The etiology of gastric antral vascular ectasia (GAVE) syndrome or gastric hyperplastic polyps (HPs) is not fully understood. We report a case of gastric HP arising in a patient treated with argon plasma coagulation (APC) for GAVE syndrome. Despite unclear etiologic progression, this and previously reported cases suggest a temporal relationship between the treatment of GAVE and HP. A 68-year-old male with a history of coronary artery disease, congestive heart failure and diabetes type II who initially presented with symptomatic anemia 2 weeks after starting aspirin and clopidogrel therapy. Diagnostic esophagogastroduodenoscopy (EGD) demonstrated diffuse GAVE. He was treated with 5 APC treatments, at 6-week intervals, over a 30 weeks period. 16 months after the initial APC treatment, an EGD performed secondary to persistent anemia demonstrated innumerable, large, bleeding polyps in the gastric antrum. Biopsy performed at that time confirmed hyperplastic gastric polyps. It has been proposed that HPs are

|i|Background|/i|. Argon plasma coagulation (APC) is useful to treat upper gastrointestinal bleeding, but its hemostatic efficacy has received little attention. |i|Aims|/i|. This investigation attempted to determine whether additional endoscopic injection before APC could improve hemostatic efficacy in treating high-risk bleeding ulcers. |i|Methods|/i|. From January 2007 to April 2011, adult patients with high-risk bleeding ulcers were included. This investigation compared APC plus distilled water injection (combined group) to APC alone for treating high-risk bleeding ulcers. Outcomes were assessed based on initial hemostasis, surgery, blood transfusion, hospital stay, rebleeding, and mortality at 30 days posttreatment. |i|Results|/i|. Totally 120 selected patients were analyzed. Initial hemostasis was accomplished in 59 patients treated with combined therapy and 57 patients treated with APC alone. No significant differences were noted between these groups in recurred bleeding, emergency surgery, 30-day

Evaporated gold and tantalum films have been bombarded with argon ions. In the case of gold films this resulted in an increase of the sheet-resistance by sputter etching to a maximum of 40 kO/[square] . The strain-gauge coefficient of resistance (gamma) (i.e. the fractional change in resistance per unit strain) was measured for films with a wide range of sheet-resistance, and was found to be almost invariant with an average of 2.6. This contrasts. greatly with the published values of gamma of up to 100 for thin island-structure evaporated films of similar sheet-resistance. The temperature coefficient of strain-gauge factor (beta) was found to be similar in magnitude but opposite in sign to the temperature coefficient of resistivity (alpha), which was measured as +12 x 104/°C. The measured values of gamma, beta and alpha agree well with values calculated assuming metallic conduction modified by reduction of the electron mean- free-path. We, therefore, conclude that a connected metallic layer ...

The effects of xenon, argon, and hydrogen on the aerobic and anaerobic metabolism of mouse liver, brain, and sarcoma slices have been investigated. Xenon was found to alter the rates of metabolism of these tissues in a manner almost identical with helium. The gas increased the rate of oxygen consumption in all three tissues and significantly depressed that of anaerobic glycolysis in brain and liver. The depression of glycolysis in sarcoma was less pronounced and not highly significant.. Although both the magnitude and statistical significance of the effects observed with argon were much smaller, there was a seeming adherence to the general pattern established by xenon and helium. Hydrogen while remaining essentially ineffective insofar as oxygen uptake was concerned, depressed glycolysis in both liver and brain slices but did not significantly affect sarcoma slices.. The following points are stressed in the Discussion: (1) the magnitude and direction of effects exerted by helium, argon, xenon, ...

Since lasers have become so powerful in dusty plasma research, it is important to determine the manner in which a laser will affect the plasma. In this work, a Verdi ™ G-Series optically pumped semiconductor laser was used in conjunction with a Langmuir probe to determine the effect (if any) that the laser has on the plasma. A Langmuir probe was used to measure and monitor various plasma parameters in a dusty argon plasma. Measurements were taken with the laser immediately beneath the probe at various plasma pressures, plasma powers, and laser powers ...

The mean age of patients was APC 65.8 ±10.03 vs. ESD 64.6 ±11.22 (p = 0.146). The mean adenoma size was 0.9 ± 0.45 cm in the APC group and 1.2 ± 0.72 cm in the ESD group (p < 0.001). The mean duration of hospital stay was significantly shorter in the APC group than the ESD group (APC 1.55 days vs. ESD 5.80 days, p < 0.001). Complication did not occur in the APC group. However, one case of perforation (0.9%) and 6 cases of bleeding (5.3%) occurred in the ESD group. Recurrence rates were 15.3% (15/97 patients) in the APC group and 3.5% (4/113 patients) in the ESD group (p = 0.003). One recurrent case of APC group was diagnosed with adenocarcinoma which was completely treated by surgery. The proportion of hospitalization was less in the APC group (43.3 %, 42/97) than the ESD group (100.0 %, 113/113) (p < 0.001). Medical expense was less in the APC group (377,172 won, 351 dollar) than the ESD group (1,430,610 won, 1,333 dollar) (p < 0.001). No complication was observed in APC treatment group by ...

AU - Kwon, Ohmyoung. PY - 2004/11. Y1 - 2004/11. N2 - A molecular dynamics study has been conducted on an external-force-field- induced isothermal crystallization process of amorphous structures as a new low-temperature athermal crystallization process. An external cyclic-force field with a dc bias is imposed on molecules selected randomly in an amorphous-phase of argon. Multiple peaks smoothed out in the radial distribution functions for amorphous states appear very clearly during the crystallization process that cannot be achieved otherwise. When the amorphous material is locally exposed to an external force field, crystallization starts and propagates from the interfacial region and crystallization growth rates can be estimated.. AB - A molecular dynamics study has been conducted on an ...

Ice bags: This type of cryotherapy makes use of simple ice bags like a plastic bag, chemical cold packs, a hot water bottle, and frozen vegetables. During this technique, first you need to dry the affected area. Place a terry cloth towel over the affected area to avoid direct contact of the ice with the skin.. Apply the ice pack for 10-15 minutes. During this process, your skin undergoes 4 stages of sensation. They include: cold, burning, aching and numbness. Immediately stop doing the therapy, whenever you feel numb.. Ice massage: This is another form of cryotherapy. Take clean tap water in a container and keep in the freezer until it is completely frozen. Take a small amount of ice and massage with it on the affected area with constant circular motion. Avoid holding the ice cube in one area for more than 3 minutes.. But, cryotherapy is not recommended for everyone. This therapy should not be used by the people who:. ...

Benign airway tumors with central airway obstruction require immediate intervention for symptoms relief. Argon Plasma Coagulation (APC) is a cheap tool readily available in hospitals.. Four patients presented for obstructing tracheal or bronchial tumor (2008 to 2011). Initial investigations included fiberoptic bronchoscopy and CT imaging of the chest. Argon plasma was set to 35 Watt and delivered in non-contact fashion through a large fiber during rigid bronchoscopy. Initially tumor coagulation was done followed by mechanical resection and finally APC was applied to tumor base. Patients were discharged next day and followed clinically by CT imaging and bronchoscopy. All patients were reevaluated one year after ablation to eliminate recurrence.. Case1: 24 years old female presented for uncontrolled asthma. Endoscopic resection with APC revealed tracheal schwannoma.. Case2: 35 years old female, 6 month pregnant, intubated for respiratory failure due to obstructive tracheal tumor. Endoscopic ...

Five patients required a second endoscopic examination because of recurrent or persistent bleeding (3.7% of cases): a man of 56 years old with Gastric Cancer who required emergency surgery, a male of 68 years old with Pancreatic cancer duodenal extension required emergency surgery, a male of 42 years with Liver Cirrhosis with a second Esophageal variceal Bleeding that was treated with another elastic band, a 31 year old female with Stomach Ulcers without new endoscopic findings, a male of 48 years old with Diabetes Mellitus type 2 had Gastric Angiodysplasia previously treated with Argon plasma without new findings (Colonoscopy revealed Angiodysplasia at Cecum and was treated with Argon Plasma coagulation). During the first half of 2012 Upper Gastrointestinal Bleeding was the indication 5.2% of all endoscopies and 8.7% of the Gastroscopies, being relevant [4].. In terms of demographic characteristics, associated medical conditions and current or recent medication it was no difference with those ...

This paper discusses the spectral features of the amplification of narrow-band radiation of atomic nitrogen in the excimeric media of inert gases, including helium, argon, krypton, and xenon. Appreciable short-wavelength shifts (up to 0.026 nm) are detected in the spectra of the amplified radiation relative to the atomic emission lines of nitrogen that initiate this radiation. The observed shifts exceeded the instrumental resolution of the spectrometer that we used, were determined by the composition of the amplifying medium, and were independent of its excitation parameters under the experimental conditions. An explanation of the observed effect is proposed.. © 2012 OSA. PDF Article ...

By the use of a closed chamber and a continuous flow of gas through this chamber a controllable welding atmosphere has been provided for experimental work. The atmosphere may be varied from 100% argon, 99.95% pure, to 100% 0(2), N(2), or any combination of these or other gases. The chamber provide a fresh gas shield in an atmosphere of the same composition as the shield. Using the controlled atmosphere chamber, welds in carbon deoxidized arc cast molybdenum are shown to be subject to hot short cracking when the oxygen content in the argon atmosphere around the arc exceeds 0.2%. The ductility of these welds was drastically reduced by the presence of more than 0.05% oxygen in the welding atmosphere. Oxygen in sintered molybdenum is shown to produce porosity and hot short cracking. However, crack and porosity free welds have been produced by using deoxidizing agents in sintered molybdenum.

BACKGROUND: In recent years, argon has been shown to exert neuroprotective effects in an array of models. However, the mechanisms by which argon exerts its neuroprotective characteristics remain unclear. Accumulating evidence imply that argon may exert neuroprotective effects via modulating the activation and polarization of microglia/macrophages after ischemic stroke. In the present study, we analyzed the underlying neuroprotective effects of delayed argon application until 7 days after reperfusion and explored the potential mechanisms. METHODS: Twenty-one male Wistar rats underwent transient middle cerebral artery occlusion or sham surgery randomly for 2 h using the endoluminal thread model. Three hours after transient middle cerebral artery occlusion induction and 1 h after reperfusion, animals received either 50% vol Argon/50% vol O2 or 50% vol N2/50% vol O2 for 1 h. The primary outcome was the 6-point neuroscore from 24 h to d7 after reperfusion. Histological analyses including infarct ...

1. Total arsenic The method described in this manual assesses arsenic exposure by analyzing urine through the use of inductively coupled-plasma dynamic reaction cell-mass spectrometry (ICP-DRC-MS). Urine is analyzed because urinary excretion is the major pathway for eliminating arsenic from the mammalian body. This method achieves rapid and accurate quantification of total urinary arsenic. Total urine arsenic concentrations are determined by using ICP-DRC- MS. This multielement analytical technique is based on quadrupole ICP-MS technology and includes DRC™ technology, which minimizes or eliminates much argon-based polyatomic interference. Coupling radio frequency power into a flowing argon stream seeded with electrons creates the plasma, the heat source, which is ionized gas suspended in a magnetic field. Predominant species in the plasma are positive argon ions and electrons. Diluted urine samples are converted into an aerosol by using a nebulizer inserted within a spray chamber. A portion of ...

Argon (Greek ἀργόν, neuter singular form of ἀργός meaning lazy or inactive), is named in reference to its chemical inactivity. This chemical property of this first noble gas to be discovered impressed the namers.[12][13] An unreactive gas was suspected to be a component of air by Henry Cavendish in 1785.[14] Argon was first isolated from air in 1894 by Lord Rayleigh and Sir William Ramsay at University College London by removing oxygen, carbon dioxide, water, and nitrogen from a sample of clean air.[15][16][17] They first accomplished this by replicating an experiment of Henry Cavendishs. They trapped a mixture of atmospheric air with additional oxygen in a test-tube (A) upside-down over a large quantity of dilute alkali solution (B), which in Canvendishs original experiment was potassium hydroxide,[14] and conveyed a current through wires insulated by U-shaped glass tubes (CC) which sealed around the platinum wire electrodes, leaving the ends of the wires (DD) exposed to the ...

Abstract Glow discharges are used in a large number of applications, and it is one of the most common plasmas used in industry. The most important application of glow discharges is probably in microelectronic

A method for coagulating tissue during endoscopic surgery by using argon plasma coagulation is described. An endoscope is used having a flexible, hollow tube inserted through one of the working channels of the endoscope. Inside the tube an electrode is arranged stationarily being offset from the exit opening at the distal end of the tube in such a manner that the electrode cannot come into contact with the tissue. Argon or another inert gas is supplied from a source of gas through the tube to the exit opening with such a low flow rate that gas exiting through the exit opening is a non laminar stream which forms an inert gas atmosphere between the distal end of the tube and the region of the tissue to be coagulated, while the exit is maintained at a distance from the tissue to be coagulated, whereby the area of tissue to be coagulated is positioned sidewardly of the extended longitudinal axis of the protruding end portion of the tube.

Ultra high purity gases usually cost more than gases of lower purities due to the process involved in making the gases. One such method of purification uses filters of decreasing pore size to remove larger particles as the gas enters, and smaller particles as the gas continues through, such that enough impurities are removed from the gas to achieve Ultra High Purity.. Speciality Gases provides certified ultra pure gases i.e. Nitrogen, Argon, Helium, Zero Air, Hydrogen to be used as carrier gas in Gas Chromatographs (GCs) and other analytical instruments.. Our ultra pure gases have stringent high-purity specifications. We achieve consistent high-purity through extensive gas cylinder preparation, dedication of gas cylinders for gas service and quality control at every step.. By using our High purity Gases you will optimize cost and quality of analytical results, regardless of application and significantly extend the life of GC columns, detectors and instruments.. ...

Guided by CALPHAD (Calculation of Phase Diagrams) modeling, the refractory medium-entropy alloy MoNbTaV was synthesized by vacuum arc melting under a high-purity argon atmosphere. A body-centered cubic solid solution phase was experimentally confirmed in the as-cast ingot using X-ray diffraction and scanning electron microscopy. The measured lattice parameter of the alloy (3.208 Å) obeys the rule of mixtures (ROM), but the Vickers microhardness (4.95 GPa) and the yield strength (1.5 GPa) are about 4.5 and 4.6 times those estimated from the ROM, respectively. Using a simple model on solid solution strengthening predicts a yield strength of approximately 1.5 GPa. Thermodynamic analysis shows that the total entropy of the alloy is more than three times the configurational entropy at room temperature, and the entropy of mixing exhibits a small negative departure from ideal mixing.

Calculations were carried out to study the effectiveness of a gas curtain for mitigating contamination form hydrocarbon gases in extreme UV (EUV) lithography tools. The momentum, energy and mass transport in the curtain and surrounding regions were calculated using a 2D finite volume model of a lithography tool. Argon was used for the gas curtain. The results from the calculations quantify the relationship between the argon flow rate and the hydrocarbon partial pressure in the region of the optical elements. In general, the hydrocarbon partial pressure decreases as the mass transfer Peclet number, Pe equals Vh/D, increases, where V is the velocity of the argon, h is the thickness of the gas curtain and D is the mass diffusivity. An argon flow rate of 12.2 torr 1/s is required to reduce the hydrocarbon partial pressure from 10-7 to 10-10 torr in the specific lithography tool considered here. The EUV transmission in the tool with the gas curtain is 0.93. This is a large improvement over the 0.5 ...

0025] All preparations and manipulations of catalysts were carried out under hydrogen or argon atmospheres with the use of standard Schlenk, vacuum line and glove box techniques in dry, oxygen-free solvents. Tetrahydrofuran (THF), toluene, dichloromethane, diethyl ether (Et2O) and hexanes were purified and dried using an Innovative Technologies solvent purification system. Methanol, ethanol and 2-propanol were dried by refluxing and distilling over the respective magnesium alkoxide, and collecting and storing the solvent over activated molecular sieves. Chiral diphosphines were obtained from Kanata Chemical Technologies Inc. Deuterated solvents were degassed and dried before use. NMR spectra were recorded on a Varian Unity Inova 300 MHz spectrometer (300 MHz for 1H, 75 MHz for 13C and 121.5 for 31P). All 31P chemical shifts were measured relative to 85% H3PO4 as an external reference. The 1H and 13C chemical shifts were measured relative to partially deuterated solvent peaks but are reported ...

A mixture of styrene (44.2 g, 424 mmol) and Rh2(S-DOSP)4 (1.58 g, 0.85 mmol) in pentane (350 mL) was stirred at -78° under an argon atmosphere. To this solution was added methyl (E)-2-diazo-4-phenyl-3-butenoate (17.2 g, 84.8 mmol) in pentane (0.12 M) over 30 minutes, and the reaction mixture was then stirred at -78° for 24 hours. The mixture was then concentrated in vacuo, and the residue was purified on silica using ether/petroleum ether (0:100 to 10:90) as the eluent to give (1S,2S)-methyl 2β-phenyl-1β-[2-(Z)-styryl]cyclopropane-1α-carboxylate (16.05 g, 68%) as a white solid (mp 57-60°; 98% ee); IR ( CHCl3) 3110, 3090, 3060, 2980, 2950, 2880, 1735 cm-1; 1H NMR (148) ( CDCl3) 1.85 (dd, J = 7.3, 5.1 Hz, 1 H), 2.05 (dd, J = 9.1, 5.1 Hz, 1 H), 3.04 (dd, J = 9.1, 7.3 Hz, 1 H), 3.77 (s, 3 H), 6.15 (d, J = 15.9, 1 H), 6.37, (d, J = 15.9 Hz, 1 H), 7.12-7.28 (m, 10 H); 13C NMR ( CDCl3) 18.5, 33.2, 34.9, 52.3, 124.0, 126.1, 126.7, 127.2, 127.9, 128.3, 129.0, 133.0, 135.4, 137.0, 174.1; [α]25D - ...

A study was made of the effects of laser radiation on the structure and function of the primate retina. The program encompasses the ocular effects of pulsed and CW laser radiation through: (1) Anatomical studies of laser-exposed and non-exposed tissue at the resolution of both light and electron optics. These are directed toward studies of the chemical morphology of retinal structures through enzyme and other staining techniques. (2) Analysis of bioelectric potentials in the visual system. The electroretinogram recorded from the intact eye is used to follow long-term effects of laser radiation. The LERG (localized electroretinogram) will be used to study localized effects of laser radiation. Single unit recording from the fourth-order neurons (LGN) of the visual system will be used to study photochemical effects of laser radiation. (3) Laser-induced changes in retinal metabolism are being investigated through autoradiographic studies of C14 labeled vitamin A. (4) Laser exposures of the macula

Residence timescales of silicic magma chambers in the earths crust are poorly known. Some recent determinations of these timescales, based on 40Ar/39Ar analysis of quartz hosted melt inclusions, may be flawed due to the problem of excess argon (40ArE) in trapped melt. In order to quantitatively assess the influence of 40ArE on estimated magma chamber ages, we sampled melt inclusion bearing quartz (MIBQ) from plinian pumice deposits of the Bishop Tuff (0.76 ± 0.01 Ma) in Long Valley, California, and the Lower (1.61 ± 0.01 Ma) and Upper Bandelier Tuffs (1.22 ± 0.02 Ma) from the Jemez Mountains west of Los Alamos, New Mexico. Three types of glass are observed in the MIBQ. First, non-vesicular glass adhered to the outside of the crystal; second, hourglass inclusions (inclusions that are not fully enclosed within the crystal and may have been in free exchange with atmosphere at the time of eruption); and third, fully trapped melt inclusions. Each sample was prepared for analysis in three ways: ...

We report on the application of a novel all-solid-state violet laser diode source to confocal microscopy. The source has the potential to replace argon ion lasers in a range of fluorescence based imaging systems. Improvements in system performance and image quality through the use of anamorphic prisms to modify the beam profile have been characterised. These modifications have permitted high quality, optically sectioned images to be obtained from laser diodes operating around 406nm. Living mammalian cells stained with a range of biologically significant fluorophores have been imaged. In addition, it has been shown that at this wavelength it is possible to image dyes that normally require excitation with UV argon laser lines.. ...

Titanium and its alloys-including e.g., the wellproven TiAl6V4 alloy or multi-element beta titanium (β-Ti) alloys such as β-TiNb35Zr7Ta5, are lightweight, strong and stable materials used in many industries as well as in biomedical applications. However, they suffer from inferior friction and wear resistance, and this is why a variety of surface modification techniques such as thermal and anodic oxidation, gas nitriding and ion implantation have been subject to numerous studies in connection with surface treatments of titanium materials. In particular, nitriding is seen as a promising (and already proven) method applied to improve the surface (mainly, tribological) properties and corrosion resistance of these materials. An advanced technique adopted to introduce nitrogen into the titanium surface is ion implantation; it can be performed even at low temperatures and is effective when fluences higher than ca. 5·1016 cm−2 are employed. A mixed surface layer containing nitride is formed which ...

Essentially the concept exploits a natural phenomenon we see taking place in space, said Walker. When the solar wind - a plasma of electrified gas released by the Sun - hits the magnetic field of the Earth, it creates a boundary consisting of two plasma layers. Each layer has differing electrical properties and this can accelerate some particles of the solar wind across the boundary, causing them to collide with the Earths atmosphere and create the aurora.. The new ESA study confirms the earlier Australian findings by showing that under carefully controlled conditions, the double layer could be formed and remains stable, allowing the constant acceleration of charged particles in a beam. ESA also confirmed that stable double layers could be created with different propellant gas mixtures.. The double layer was created using a radio antenna wound around a tube. A continuous supply of argon gas was pumped into the tube and the antenna transmitted radio waves which ionized the argon, creating a ...

Successful fabrication by the semiconductor industry of the sophisticated devices that are now ubiquitous depends on highly reliable processing; fundamental to these processes is accurate doping using ion implantation. Industry has well-established methods for validation of a limited number of processes, but research labs need to be able to accurately reproduce a much larger range of processes for a wide variety of purposes. Some examples of these purposes include, in no particular order: establishing processes for the fabrication of new types of devices,1 or devices in new materials;2 simulating defect production in nuclear materials;3 controlled surface modification to improve biofouling behaviour;4 creating new materials impossible to make by equilibrium methods which can involve very different processes such as high fluence implantation5,6 or defect engineering.7 Ion implantation is an intrinsically controllable process, involving ion beams of well-defined energies: the physics of the ...

Our study has several limitations. Few articles were included in the analysis. However, this is because of the small number of RCTs published on this subject. All included studies were conducted in Egypt, which has one of the highest cirrhosis-related death rates in the world [51]. Nonetheless, our results were consistent with previous observational studies conducted in other countries as well [32,33,35]. Not all outcomes were evaluated in every trial. Significant heterogeneity was identified among the studies, which might be explained by the following reasons: the severity of the liver disease varied among the studies, as shown in Supplementary Table 4, and different APC settings along with a variable number of endoscopic bands applied in each session. These factors may have influenced the outcomes. One of the included studies was performed in children with liver disease [39]. However, the results were consistent with those of other studies, probably due to the same pathophysiology in patients ...

Purpose: : To investigate the effect of panretinal photocoagulation on the crystalline lens anterior capsula and lens epithelial cells. Methods: : This prospective, histological, mono-blind study was performed on 20 consecutive cases (20 eyes) who undergone to uncomplicated phacoemulsification surgery for senile nuclear sclerosis (P-1 or less, N-V, C-1 or less according to LOCS). Age of patients varied between 60 to 75 years. They had no complicating systemic or ocular disease except type-2 diabetes mellitus (DM) and hypertension. They were divided into groups according to (1) presence of DM, (2) severity of diabetic retinopathy (DR), and (3)argon laser panretinal photocoagulation (PRP) performed at least 6 months earlier. Lens anterior capsula materials taken from all the patients during phacoemulsification operation were examined with transmission electron microscopy (TEM) by the same treatment-blind histologist.

The causative agent is known to be Human Papilloma Virus infection which can lead to dysplastic changes in the anus, detectable by High Resolution Anoscopy with biopsies. The analysis of the abnormal tissue can then be graded as Anal Intraepithelial Neoplasia 1 to 3, with AIN 2 or 3 considered as high grade dysplasia. These lesions are cancer precursors, but the proportion of lesions progressing to invasive anal cancer and the time to event are unknown. There is currently no recognized treatment to offer as standard of care although it is of general belief that treating these lesions, as it is done for women with CIN 2 and 3 (Cervical Intraepithelial Neoplasia) could help decrease the number of progressions to invasive anal cancer in MSM ...

TY - GEN. T1 - Degradation of dye waste Remazol Brilliant Red using the contact glow discharge electrolysis method in a circulation reactor by air injection and NaCl solution. AU - Coan, Chantika Putri Febianty. AU - Cendian, Novy. AU - Saksono, Nelson. PY - 2020/9/3. Y1 - 2020/9/3. N2 - Contact Glow Discharge Electrolysis is a process of electrolysis with DC current to form electric sparks due to the electrons that undergo plasma excitation in the electrolyzed solution. Plasma electrolysis produce hydroxyl radicals, a powerful oxidant, with greater amount than other advanced oxidation method. This method is used to degrade much weight organic compounds such as dye. This research aims to evaluate the degradation of dye waste Remazol Brilliant Red (RBR) using Contact Glow Discharge Electrolysis method with air injection. The injection of air can increase hydroxyl radicals production and can decrease energy consumption. The condition used are dye concentration is 100 mg/L, NaCl 0,03 M, in addition ...

Before going incommunicado behind the Sun for a month, NASA¿s Mars Curiosity rover sent Earth evidence that the Red Planet has lost much of its original atmosphere. The findings, announced by Jet Propulsion Laboratory, bolster the idea that the Martian atmosphere was once much thicker than it is today, less than a month after the rover drilled its first rock and found signs Mars was once hospitable to life. Curiosity¿s Sample Analysis at Mars instrument tasted a sample of Martian atmosphere and counted up the abundance of isotopes of argon in the air. The researchers looked at two isotopes of argon, the heavier argon-38 and the lighter argon-36. They found that while there was four times as much argon-36 as argon-38, this ratio wasn¿t nearly as much as expected, based on data from other parts of the solar system.

Results Fifty SSc patients were diagnosed with GAVE. Seventeen patients (34%) suffered of symptomatic anemia and were treated with argon plasma coagulation (APC) for a mean (SD) of 4.5 (4.3) sessions per patient. The mean (SD) hemoglobin was 9.4 (1.7) gr% in the group who required endotherapy compared to 11.5 (1.3) in the group which did not need any intervention. Four patients needed more than 6 sessions of treatment. Mean (SD) follow up was 4.1 (2.4) years. Nine patients required a total of 73 packed blood cells units and another 4 had intravenous iron replacement. Four patients died during the first 2 years after diagnosis, none of them due to bleeding complications. None of the patients that survived more than 2 years required further endotherapy or blood transfusions. No significant complications of APC occurred. Interestingly, all those who survived,had received immunotherapy with cyclophosphamide or mycophenolate mofetil due to multisystem involvement and disease activity. ...

Noble gases such as xenon and argon have been reported to provide neuroprotection against acute brain ischemic/anoxic injuries. by xenon was mimicked by two noncompetitive antagonists of NMDA glutamate receptors, memantine and ketamine. Each of them potentiated xenon-mediated neuroprotection when used at concentrations providing suboptimal rescue to cortical neurons but most surprisingly, no rescue at all. The survival-promoting effects of xenon persisted when NMDA was used instead of PDC to trigger neuronal death, indicating that NMDA receptor antagonism was probably accountable for xenons effects. An excess of glycine failed to invert xenon neuroprotection, hence excluding a competitive connections of xenon using the glycine-binding site of NMDA receptors. Noticeably, antioxidants such as for example N-acetylcysteine and Trolox decreased PDC-induced neuronal loss of life but xenon itself lacked free of charge radical-scavenging activity. Cholinergic neurons were rescued efficaciously by xenon ...

Aims: To describe the long-term risk of bullous keratopathy following argon laser iridotomy (ALI) in Japan and to compare it with other centres in the world.. Methods: We retrospectively reviewed the case records of all patients with ALI-induced bullous keratopathy that underwent penetrating keratoplasty at Kyoto Prefectural University of Medicine (KPUM) from January 2001 to December 2004. The results were compared with the other representative centres in Singapore and the UK.. Results: Thirty-nine eyes of 33 patients were included in the study. The mean age of patients was 73.3±6.9 years (range, 58 to 87 years). Patients developed bullous keratopathy at a mean duration of 6.9±4.9 years (range, 0.2 to 16 years) after the laser iridotomy procedure. The majority of eyes that developed bullous keratopathy (59.0%) occurred following prophylactic ALI. KPUM had the highest percentage of ALI-induced bullous keratopathy cases that underwent penetrating keratoplasties, as compared with other centres in ...

Our series appears to demonstrate that combination PDT with intravitreal triamcinolone and/or systemic immunosuppression achieved angiographic closure of the neovascular complex in all patients with concomitant improvement of vision in the majority (83%) at latest follow up. This compares favourably with the natural history of CNV in younger patients with POHS1 and PIC.2. Until recently, treatment options for inflammatory CNV were limited to observation, argon laser photocoagulation, corticosteroids, and surgical removal. Argon laser photocoagulation of subfoveal CNV is unacceptable owing to the ensuing immediate profound iatrogenic visual loss and the role of corticosteroids alone is not definitive. Flaxel et al7 demonstrated stabilisation or improvement of vision in 10 of 12 eyes with inflammatory CNV secondary to PIC or multifocal inner choroiditis following steroid therapy alone. Stabilisation of vision at 3 months has also been achieved from the use of steroids for CNV in a series of 18 ...

abstractNote = {A critical analysis of the main theories of condensation, which are due to Zwanzig, Cabrera, Mc Caroll and Ehrlich, Wanlass, Armand, and Yu and Soo, is made. A condensation coefficient equal to unity is expected from these theories, except Armand and Yu and Soo, when the temperature of the gas impinging on its own solid phase is equal or less than 300 K. Using a resonating quartz microbalance the sensitivity of which is 10{sup -9} g. cm{sup 2} the experimental data agree with these theories when the temperature of the solid is less than 20 K. However the agreement must be interpreted for the more sophisticated theories of Armand and Yu and Soo. Regarding the sublimation of the rare gases one is faced with the theories of Salter, Eyring, Goodman and Armand. Within an order of magnitude the experimental data given here agree with the expected values. Moreover Armand theory is able to give the physical meaning of the observed results for argon sublimation from a krypton or a xenon ...

An RF plasma deposition apparatus for depositing a film of material on substrates positioned in a vertical plane and electrically floating within the glow discharge. For deposition of silicon nitride films, the apparatus is adapted to introduce silane gas in a substantially uniform and laminar flow into a coating cavity containing substrates, a ground screen electrode, and a hot RF electrode, within which a glow discharge is ignited. Elemental nitrogen may be delivered to the coating cavity after being dissociated in a local, separate RF plasma called an atomizer cavity. During coating, elemental nitrogen combines with elemental silicon and deposits silicon nitride upon the substrate surface.

N2 - The cold atmospheric pressure plasma jet interaction with the bio-target is studied in the plasma experiment, 2D fluid model simulations, and with MTT and iCELLigence assays of the viability of cancer cells. It is shown, for the first time, that the use of the grounded substrate under the media with cells considerably amplifies the effect of plasma cancer cell treatment in vitro. Plasma devices with cylindrical and plane geometries generating cold atmospheric plasma jets are developed and tested. The sequence of the streamers which forms the plasma jet is initiated with a voltage of 2.5-6.5 kV applied with the frequency 40 kHz. We suggest using the grounded substrate under the ...

Chemists at Rice University have identified a chemical process for cutting carbon nanotubes into short segments. The new process is said to yield nanotubes that are suitable for a variety of applications, including biomedical sensors small enough to migrate through cells without triggering immune reactions.. The chemical cutting process involves fluorinating the nanotubes, essentially attaching thousands of fluorine atoms to their sides, and then heating the fluoronanotubes to about 1,000 Celsius in an argon atmosphere. During the heating, the fluorine is driven off and the nanotubes are cut into segments ranging in length from 20-300 nanometers.. We have studied several forms of chemical scissors, including other fluorination methods and processes that involve ozonisation of nanotubes, said John Margrave, the E.D. Butcher Professor of Chemistry at Rice University. With most methods, we see a random distribution among the lengths of the cut tubes, but pyrolytic fluorination results in a ...

Both thin films and nanowires of silver selenide were synthesized by electrodeposition from an aqueous acid electrolyte containing silver ion complexed with SCN- and selenium dioxide at room temperature. Orthorhombic Ag2Se films with Ag slightly in excess were obtained. After annealing in argon atmosphere, the films are highly (002) oriented. A positive transverse magnetoresistance of about 20-25% at T = 5 K, and 10-13% at T = 300 K, in fields of H=50 kOe were observed in the electrodeposited films. Furthermore, silver selenide nanowires were synthesized from the same aqueous system by electrodeposition in porous anodic alumina templates. X-ray diffraction (XRD), Transmission electron microscopy (TEM), and Energy dispersive absorption X-ray (EDAX) characterization results showed that the nanowires are highly crystalline with (002) growth direction after annealing. In addition, the atomic ratio of Ag/Se in the films and the nanowire samples can be controlled from about 3.0 to 2.1 by adjusting the ...

To a stirred suspension of sodium hydride (41 mg of 60% dispersion in mineral oil, 1.02 mmol) in dry dimethoxyethane (1.5 mL) under an argon atmosphere was added dropwise propofol (200 µl of 97%, 1.04 mmol) over 5 minutes and the resulting mixture was stirred for an additional 15 minutes. The resulting homogeneous solution was added dropwise to a stirred solution of chloroiodomethane (4.0 mL, 53 mmol) in dry dimethoxyethane (4 mL) over 15 minutes. This reaction mixture was stirred for two hours, filtered, and then the solvent and the excess of chloroiodomethane were evaporated. The residual oil was dissolved in toluene (HPLC-grade, 10 mL) . To this solution was added silver dibenzylphosphate (400 mg, 1.04 mmol), and the resulting mixture was refluxed for 10 minutes. After the reaction mixture was cooled down to room temperature and filtered, the solvent was evaporated in vacuo. The oily residue was purified by silica gel flash column chromatography (9:1 hexane/ethyl acetate and then 1:1 ...

2015 CSIC. Phsophogypsum is a by-product from the processing phosphate rock. Before the use of it in cement industry such as setting regulator is necessary a study of dehydration reaction of phosphogypsum to avoid the false setting during the milling. The aim is to study the thermal behavior of two different phosphogypsum sources (Spain and Tunisia) under non-isothermal conditions in argon atmosphere by using Thermo-Gravimetriy, Differential Thermal Analysis (TG-DTA) and Differential Scanning Calorimetry (DSC). DSC experiments were carried out at temperatures ranging from ambient to 350 °C at different heating rates. The temperatures of conversion from gypsum to hemihydrate and anhydrite states and heat of dehydration were determined. Various methods were used to analyze the DSC data for reaction kinetics determination. The activation energy and frequency factor were calculated for dehydration of phosphogypsum. Activation energy values of the main dehydration reaction of phosphogypsum were ...

Non-thermal atmospheric pressure plasma has drawn more and more attention to the field of wound healing research during the last two decades. It is characterized by a unique composition, which includes amongst others free radicals, ions and electrons. Furthermore, non-thermal plasma exhibits temperatures that are below those inducing thermal cell damage. Next to its well-established anti-bacterial properties, plasma can have lethal as well as stimulating effects on mammalian cells. Therefore, the medical application of non-thermal plasma on chronic wounds seems to be a promising tool to enable healing processes. However, less is known about the plasma-mediated induction of intracellular signaling pathways in human immune cells, which play a leading part in the process of wound recovery and removal of pathogens. Therefore, this thesis examined the cellular effects of a non-thermal atmospheric pressure plasma treatment on human immune cells using the argon plasma jet kinpen 09. Here, the CD4+ T ...

We report on the effect of different gaseous environments (air, argon and Ar/H2) on the structural and magnetic properties of Zn0.98Co0.02O synthesized by the solid state reaction route. We have also studied the effect of different annealing times and temperatures on the as synthesized samples. M-H curves of the air sintered and the argon annealed samples show paramagnetic behavior whereas the samples annealed in the hydrogenated argon (Ar/H2) environment exhibit ferromagnetic property at room temperature. Based on the structural and magnetic properties it has been found that Co metal clusters are responsible for the observed room temperature ferromagnetism (RTFM) in the hydrogenated samples.. ...

Experimental and analytical studies were conducted in order to extend previous knowledge of the thermal performance and gas evacuation characteristics of three selected multilayer insulation (MLI) composites. Flat plate calorimeter heat flux measurements were obtained for 20- and 80- shield specimens using three representative layer densities over boundary temperatures ranging from 39 K (70 R) to 389 K (700 R). Laboratory gas evacuation tests were performed on representative specimens of each MLI composite after initially purging them with helium, nitrogen, or argon gases. In these tests, the specimens were maintained at temperatures between 128 K (230 R) and 300 K (540 R). Based on the results of the laboratory-scale tests, a composite MLI system consisting of 112 unperforated, double-aluminized Mylar reflective shields and 113 water preconditioned silk net spacer pairs was fabricated and installed on a 1.22-m-(4-ft-) diameter calorimeter tank.

Fig. 1. Schematic illustration of proteome analysis by 2DE and mass spectrometry. In part I, proteins are separated by 2DE, stained spots are excised and subjected to in-gel digestion with trypsin, and the resulting peptides are separated by on-line capillary high-performance liquid chromatography. In part II, a peptide is shown eluting from the column in part I. The peptide is ionized by electrospray ionization and enters the mass spectrometer. The mass of the ionized peptide is detected, and the first quadrupole mass filter allows only the specific mass-to-charge ratio of the selected peptide ion to pass into the collision cell. In the collision cell, the energized, ionized peptides collide with neutral argon gas molecules. Fragmentation of the peptide is essentially random but occurs mainly at the peptide bonds, resulting in smaller peptides of differing lengths (masses). These peptide fragments are detected as a tandem mass (MS/MS) spectrum in the third quadrupole mass filter where two ion ...

Low-pressure sodium (LPS) lamps have a borosilicate glass gas discharge tube (arc tube) containing solid sodium, a small amount of neon, and argon gas in a Penning mixture to start the gas discharge. The discharge tube may be linear (SLI lamp)[3] or U-shaped. When the lamp is first started, it emits a dim red/pink light to warm the sodium metal; within a few minutes as the sodium metal vaporizes, the emission becomes the common bright yellow. These lamps produce a virtually monochromatic light averaging a 589.3 nm wavelength (actually two dominant spectral lines very close together at 589.0 and 589.6 nm). The colors of objects illuminated by only this narrow bandwidth are difficult to distinguish. LPS lamps have an outer glass vacuum envelope around the inner discharge tube for thermal insulation, which improves their efficiency. Earlier LPS lamps had a detachable dewar jacket (SO lamps).[4] Lamps with a permanent vacuum envelope (SOI lamps) were developed to improve thermal insulation.[5] ...

Can cryotherapy help to relieve physical pain? Cryotherapy treatment can relieve, stop, and prevent physical pain and swelling by treating the underlying cause of the issue or by helping to reduce or eliminate pain. Cryotherapy means cold therapy. Have you ever placed a bag of frozen peas on an injury such as a swollen ankle? Then youve applied a very basic form of cryotherapy! Treatment by cryotherapy is the I part of RICE (rest, ice, compression, elevation). The benefits of using cryotherapy treatment to reduce pain include reduction of nerve activity, pain and swelling reduction, and lower skin temperature. But why does decreasing skin temperature work? It depends if its applied in a highly targeted way or to trigger your whole body to react in a certain way. For example, skin conditions can be very painful, itchy, and embarrassing, so localised (or partial body) cryotherapy treatment can be used. Application of liquid nitrogen (or argon gas) to affected areas of the skin, results in ...

The interaction of nitrogen, oxygen, and hydrogen plasmas with spin-coated arrays of colloidal cobalt-platinum particles was investigated with a large variety of microscopic and spectroscopic techniques. It could be demonstrated that the organic ligands of the nanoparticles can be completely removed. Yet, due to the short (∼1.6 nm) interparticle distances within the layers, strong degradation and sintering effects are observed after hydrogen and nitrogen plasma treatments. In the case of oxygen plasma, the shape and size of the individual particles are unaffected and can be preserved, even if a short hydrogen plasma is subsequently applied to reduce the particles back to their metallic state. Nevertheless, the mesoscopic order of the particle arrays is slightly decreased as observed by the breakup of larger ordered areas into smaller domains forming island-trench structures. Probing the surface chemistry of the particles with temperature programmed desorption, a rather complex surface ...

Recent research has shown amounts of krypton are enhanced relative to those of argon and helium in CO2 captured from a nitrate fertiliser plant in Brazil. This enrichment is due to the greater solubility of the heavier noble gases, so they are more readily dissolved into the solvent used for capture. This fingerprint has been shown to act as an effective means of tracking CO2 injected into Brazilian and USA oil fields to increase oil production. Similar enrichments in heavy noble gases, along with high helium concentrations are well documented in coals, coal-bed methane and in organic rich oil and gas source rocks. As noble gases are unreactive, these enrichments will not be affected by burning the gas or coal in a power station and hence will be passed onto the flue gases. Samples of CO2 obtained from an oxyfuel pilot CO2 capture plant at Lacq in France which contain helium and krypton enrichments well above atmospheric values confirm this ...

A new method is demonstrated for optically trapping micron-sized absorbing particles in air and obtaining their single-particle Raman spectra. A 488-nm Gaussian beam from an Argon ion laser is transformed by conical lenses (axicons) and other optics into two counter-propagating hollow beams, which are then focused tightly to form hollow conical beams near the trapping region. The combination of the two coaxial conical beams, with focal points shifted relative to each other along the axis of the beams, generates a low-light-intensity biconical region totally enclosed by the high-intensity light at the surface of the bicone, which is a type of bottle beam. Particles within this region are trapped by the photophoretic forces that push particles toward the low-intensity center of this region. Raman spectra from individual trapped particles made from carbon nanotubes are measured. This trapping technique could lead to the development of an on-line real-time single-particle Raman spectrometer for ...
