Factors influencing the analytical performance of an atmospheric sampling glow discharge ionization source as revealed via ionization dynamics modeling. (1/24)

A kinetic model is developed for the dynamic events occurring within an atmospheric sampling glow discharge that affect its performance as an ion source for analytical mass spectrometry. The differential equations incorporate secondary electron generation and thermalization, reagent and analyte ion formation via electron capture and ion-molecule reactions, ion loss via recombination processes, diffusion, and ion-molecule reactions with matrix components, and the sampling and pumping parameters of the source. Because the ion source has a flow-through configuration, the number densities of selected species can be estimated by applying the steady-state assumption. However, understanding of its operation is aided by knowledge of the dynamic behavior, so numerical methods are applied to examine the time dependence of those species as well. As in other plasma ionization sources, the ionization efficiency is essentially determined by the ratio of the relevant ion formation and recombination rates. Although thermal electron and positive reagent ion number densities are comparable, the electron capture/ion-molecule reaction rate coefficient ratio is normally quite large and the ion-electron recombination rate coefficient is about an order of magnitude greater than that for ion-ion recombination. Consequently, the efficiency for negative analyte ion formation via electron capture is generally superior to that for positive analyte ion generation via ion-molecule reaction. However, the efficiency for positive analyte ion formation should be equal to or better than that for negative analyte ions when both ionization processes occur via ion-molecule reaction processes (with comparable rate coefficients), since the negative reagent ion density is considerably less than that for positive reagent ions. Furthermore, the particularly high number densities of thermal electrons and reagent ions leads to a large dynamic range of linear response for the source. Simulation results also suggest that analyte ion number densities might be enhanced by modification of the standard physical and operating parameters of the source.  (+info)

Millisecond pulsed radio frequency glow discharge time of flight mass spectrometry: temporal and spatial variations in molecular energetics. (2/24)

The internal energy distributions, P(epsilon), of a millisecond pulsed radio frequency glow discharge plasma were investigated using tungsten hexcarbonyl W(CO)(6) as a "thermometer molecule". Vapor of the probe molecule, W(CO)(6), was introduced into the plasma and subjected to various ionization and excitation processes therein. The resultant molecular and fragment ions were monitored using a Time-of-Flight mass spectrometer. Ion abundance data were utilized in combination with the known energetics of W(CO)(6) to construct the P(epsilon) plots. The P(epsilon) of W(CO)(6) exhibited strong temporal dependence over the pulse cycle: Distinct internal energy distributions were found at the discharge breakdown period (prepeak), the steady state period (plateau), and the post-pulse period (afterpeak). Spatial variation in P(epsilon) was also observed, especially during the plateau regime. The observations suggest that this pulsed glow discharge affords excellent energy tunability that can be used to perform selective ionization and fragmentation for molecular, structural, and elemental information. Parametric studies were performed to evaluate the effects of discharge pressure and operating power on P(epsilon). These studies also provided insight into the correlation of the observed P(epsilon)s with the fundamental ionization and excitation mechanisms in the plasma. The temporal and spatial variations in P(epsilon) were hence attributed to changes in the dominant energy transfer processes at specific times in specific regions of the plasma. These data will be useful in future efforts to optimize the analytical performance of this source for chemical speciation.  (+info)

Comparison of electrospray ionization, atmospheric pressure chemical ionization, and atmospheric pressure photoionization for the analysis of dinitropyrene and aminonitropyrene LC-MS/MS. (3/24)

The only relevant source for human exposure to dinitropyrenes is diesel engine emissions. Due to this specificity, dinitropyrenes may be used as biomarkers for monitoring human exposure to diesel engine emissions. Only few analytical methods have been described for the quantitation of dinitropyrenes and their metabolites, aminonitropyrenes, and diaminopyrenes. Therefore, for dinitropyrenes, aminonitropyrenes, and diaminopyrenes were selected as model compounds for the development of a sensitive HPLC-MS/MS method (high performance liquid chromatography coupled to triple quadrupole mass spectrometry) was to quantify polyaromatic amines and nitroarenes in biological matrices was developed optimal methods by comparing electrospray ionization (ESI), atmospheric pressure chemical ionization (APCI), and atmospheric pressure photoionization (APPI) sources. Dinitropyrene was not effectively ionized and diaminopyrene yielded mainly [M(.)](+) ions by electrospray ionization. With APCI and APPI, precursor ions of diaminopyrene and aminonitropyrene were [M + H](+) and [M(.)](-) for dinitropyrene. Precursor ions with [M - 30(.)](-) for dinitropyrene and [M - 30 + H](+) for aminonitropyrene were observed. Reversed and normal phase HPLC-MS/MS with ESI, APCI and APPI were optimized separately with respect to unequivocal analyte identification and sensitivity. Normal phase HPLC coupled to APPI-MS/MS gave the highest precision and sensitivity for aminonitropyrene (6%/0.2 pg on column) and dinitropyrene (9%/0.5 pg on column). The limit of detection in spiked rat plasma was 5 pg/100 microL for aminonitropyrene (accuracy 82%) and 10 pg/100 microL for dinitropyrene (accuracy 105%). In plasma of rats treated with dinitropyrene by oral administration, no detectable levels of dinitropyrene but higher aminonitropyrene levels compared with intratracheal instillation were observed. These findings clearly demonstrate that dinitropyrene was absorbed after oral and intratracheal application and that a reduction of nitro groups occurs to a high extent in the reductive environment of the intestine. To our knowledge, this is the first time that aminonitropyrene was observed in plasma after intratracheal or oral administration directly demonstrating the reductive metabolism of dinitropyrene in vivo.  (+info)

Studies on the effects of ionization on bacterial aerosols in a burns and plastic surgery unit. (4/24)

The effect of the ionization of the air on the decay of bacterial aerosols was studied in a Burns and Plastic Surgery Unit. Ions were generated by free corona needles. The air content of bacteria measured by settle plates was found to be smaller during the ionization period than during the controls period. The number of individual phage typed Staph. aureus strains was especially found to be lower during ionization. The opposite potential increased the disappearance of bacteria from the air. The size of skin particles carrying bacteria is not optimum, but the results obtained show that the ionization may have applications in controlling airborne infection.  (+info)

Reduced flavin: NMR investigation of N5-H exchange mechanism, estimation of ionisation constants and assessment of properties as biological catalyst. (5/24)

BACKGROUND: The flavin in its FMN and FAD forms is a versatile cofactor that is involved in catalysis of most disparate types of biological reactions. These include redox reactions such as dehydrogenations, activation of dioxygen, electron transfer, bioluminescence, blue light reception, photobiochemistry (as in photolyases), redox signaling etc. Recently, hitherto unrecognized types of biological reactions have been uncovered that do not involve redox shuffles, and might involve the reduced form of the flavin as a catalyst. The present work addresses properties of reduced flavin relevant in this context. RESULTS: N(5)-H exchange reactions of the flavin reduced form and its pH dependence were studied using the 15N-NMR-signals of 15N-enriched, reduced flavin in the pH range from 5 to 12. The chemical shifts of the N(3) and N(5) resonances are not affected to a relevant extent in this pH range. This contrasts with the multiplicity of the N(5)-resonance, which strongly depends on pH. It is a doublet between pH 8.45 and 10.25 that coalesces into a singlet at lower and higher pH values. From the line width of the 15N(5) signal the pH-dependent rate of hydrogen exchange was deduced. The multiplicity of the 15N(5) signal and the proton exchange rates are little dependent on the buffer system used. CONCLUSION: The exchange rates allow an estimation of the pKa value of N(5)-H deprotonation in reduced flavin to be >or= 20. This value imposes specific constraints for mechanisms of flavoprotein catalysis based on this process. On the other hand the pK asymptotically equal to 4 for N(5)-H protonation (to form N(5)+-H2) would be consistent with a role of N(5)-H as a base.  (+info)

Hospital-acquired legionnaires disease in a university hospital: impact of the copper-silver ionization system. (6/24)

We evaluated the impact of the copper-silver ionization system in a hospital where hyperendemic nosocomial legionellosis and was present and all previous disinfection measures had failed. After implementation of the copper-silver ionization system, environmental colonization with Legionella species decreased significantly, and the incidence of nosocomial legionellosis decreased dramatically, from 2.45 to 0.18 cases per 1000 patient discharges.  (+info)

Bactericidal action of positive and negative ions in air. (7/24)

BACKGROUND: In recent years there has been renewed interest in the use of air ionisers to control of the spread of airborne infection. One characteristic of air ions which has been widely reported is their apparent biocidal action. However, whilst the body of evidence suggests a biocidal effect in the presence of air ions the physical and biological mechanisms involved remain unclear. In particular, it is not clear which of several possible mechanisms of electrical origin (i.e. the action of the ions, the production of ozone, or the action of the electric field) are responsible for cell death. A study was therefore undertaken to clarify this issue and to determine the physical mechanisms associated with microbial cell death. RESULTS: In the study seven bacterial species (Staphylococcus aureus, Mycobacterium parafortuitum, Pseudomonas aeruginosa, Acinetobacter baumanii, Burkholderia cenocepacia, Bacillus subtilis and Serratia marcescens) were exposed to both positive and negative ions in the presence of air. In order to distinguish between effects arising from: (i) the action of the air ions; (ii) the action of the electric field, and (iii) the action of ozone, two interventions were made. The first intervention involved placing a thin mica sheet between the ionisation source and the bacteria, directly over the agar plates. This intervention, while leaving the electric field unaltered, prevented the air ions from reaching the microbial samples. In addition, the mica plate prevented ozone produced from reaching the bacteria. The second intervention involved placing an earthed wire mesh directly above the agar plates. This prevented both the electric field and the air ions from impacting on the bacteria, while allowing any ozone present to reach the agar plate. With the exception of Mycobacterium parafortuitum, the principal cause of cell death amongst the bacteria studied was exposure to ozone, with electroporation playing a secondary role. However in the case of Mycobacterium parafortuitum, electroporation resulting from exposure to the electric field appears to have been the principal cause of cell inactivation. CONCLUSION: The results of the study suggest that the bactericidal action attributed to negative air ions by previous researchers may have been overestimated.  (+info)

The detection of airborne transmission of tuberculosis from HIV-infected patients, using an in vivo air sampling model. (8/24)

BACKGROUND: Nosocomial transmission of tuberculosis remains an important public health problem. We created an in vivo air sampling model to study airborne transmission of tuberculosis from patients coinfected with human immunodeficiency virus (HIV) and to evaluate environmental control measures. METHODS: An animal facility was built above a mechanically ventilated HIV-tuberculosis ward in Lima, Peru. A mean of 92 guinea pigs were continuously exposed to all ward exhaust air for 16 months. Animals had tuberculin skin tests performed at monthly intervals, and those with positive reactions were removed for autopsy and culture for tuberculosis. RESULTS: Over 505 consecutive days, there were 118 ward admissions by 97 patients with pulmonary tuberculosis, with a median duration of hospitalization of 11 days. All patients were infected with HIV and constituted a heterogeneous group with both new and existing diagnoses of tuberculosis. There was a wide variation in monthly rates of guinea pigs developing positive tuberculin test results (0%-53%). Of 292 animals exposed to ward air, 159 developed positive tuberculin skin test results, of which 129 had laboratory confirmation of tuberculosis. The HIV-positive patients with pulmonary tuberculosis produced a mean of 8.2 infectious quanta per hour, compared with 1.25 for HIV-negative patients with tuberculosis in similar studies from the 1950s. The mean monthly patient infectiousness varied greatly, from production of 0-44 infectious quanta per hour, as did the theoretical risk for a health care worker to acquire tuberculosis by breathing ward air. CONCLUSIONS: HIV-positive patients with tuberculosis varied greatly in their infectiousness, and some were highly infectious. Use of environmental control strategies for nosocomial tuberculosis is therefore a priority, especially in areas with a high prevalence of both tuberculosis and HIV infection.  (+info)

We investigated this study to generate a patient related verification procedure for Rapid Arc treatment plans.. Before we started to generate the verification protocol we investigated measurements to analyse the potential of the MatriXX for unblocked photon arc fields. The MatriXX response showed good agreements between calculated and measured dose distribution for field sizes of 7 cm × 7 cm and 24 cm × 24 cm with a passing rate between 99% and 100%. Higher aberrations were found for smaller field sizes than 7 cm × 7 cm and for larger field sizes than 24 cm × 24 cm. During Rapid Arc verification measurement we measured the whole dose distribution which consists of 177 control points (177 beam directions with different MLC shapes and gantry speeds between each beam direction). 2/177 beams irradiated perpendicular through the MatriXX. In addition a range of control points irradiated near lateral through the MatriXX. The advantage of the MatriXX is cylindrical parallel plate chambers. Our ...
Parents of kids with allergies should use environmental control measures to reduce their childs exposure to allergy triggers. Some are easy to do, but others can be costly or fairly time-consuming.. Talk with your doctor or health care provider about starting with environmental control measures that will limit the allergens and irritants causing immediate problems.. Because allergies develop over time with continued exposure to allergens, the doctor also may suggest taking precautions now so your child doesnt develop new allergies. For example, dust mites might not be a trigger, but could become one with continued exposure - so controlling them now could help prevent them from becoming an allergy trigger.. Here are suggested environmental control measures for different allergens and irritants:. ...

Cecil replies: Maybe its just me, but when I hear somebody go on about revolutionary discoveries, negative high energy, or anything to do with ions (which are what a corona discharge device produces), I make sure Ive got a firm grip on my wallet.

The study shows that krypton-85 from nuclear fission enhances air ionization and, thus, interferes with the atmospheric-electrical system and the water balance of the earth atmosphere. This is reason for concern: There are unforeseeable effects for weather and climate if the krypton-85 content of the earth atmosphere continues to rise. There may be a krypton-specific greenhouse effect and a collapse of the natural atmospheric-electrical field. In addition, human well-being may be expected to be impaired as a result of the diminished atmospheric-electrical field. There is also the risk of radiochemical actions and effects caused-by krypton-85-containing plumes in other air-borne pollutants like the latters transformation to aggressive oxidants. This implies radiation smog and more acid rain in the countries exposed. This study summarizes findings gained in these issues by various sciences, analyses them and elaborates hypotheses on the actions and effects of krypton-85 on the air, the atmosphere ...
Consumer Reports, a non-profit US-based product-testing magazine, reported in October 2003 that air ionisers do not perform to high enough standards compared to conventional HEPA filters. The exception was a combination unit that used a fan to move air while ionizing it. In response to this report, The Sharper Image, a manufacturer of air ionisers (among other products), sued Consumers Union (the publishers of Consumer Reports) for product defamation. Consumer Reports gave the Ionic Breeze and other popular units a fail because they have a low Clean Air Delivery Rate (CADR). CADR measures the amount of filtered air circulated during a short period of time, and was originally designed to rate media-based air cleaners. The Sharper Image claimed that this test was a poor way to rate the Ionic Breeze, since it does not take into account other features, such as 24-hour-a-day continuous cleaning, ease of maintenance, and silent operation. The United States District Court for the Northern District ...

Surfaces of hydrophobic polymers are treated to reduce their friction resistance characteristics when in contact with an aqueous environment by exposing the surfaces to an oxidation treatment, preferably by use of radio frequency glow discharge. This oxidation is followed by exposure to atmospheric air, until there is a substantial reduction in the air-water contact angle of the surfaces. The reduced friction resistance characteristics are important in aqueous applications where there is movement between the surfaces of two polymeric materials, such as in double slideable catheters and similar medical products. This process also provides lower coefficients of friction for general polymeric products in contact with water and aqueous solutions.

In the last decade, diverse strategies in surface modification have been applied on implantable biomaterials such as hydroxyapatite (HA) [1], low-density polyethylene (LDPE) [2] and poly(l-lactic-co-glycolic acid) (PLGA) [3] to improve their intended functions in the body. One of the main purposes for surface modification is to enhance or inhibit protein adsorption on the surface of biomaterials. For example, plasma surface-modification (PSM) techniques such as radio frequency glow discharge have been tested to alter the surface functionalities and, therefore modulate protein adsorption [4] and cell adhesion to biomaterials [5]. Higher reproducibility in surface treatment and flexibility to obtain different surface characteristics, such as surface charge [6], energy [7] and chemistry [8] were achieved using PSM.. The interactions between proteins and surface of biomaterials are mainly energetic. In particular, the van der Waals, electrostatic, hydrogen bonding and hydrophobic interactions are ...

It is our belief that the first line of defense against allergy is environmental control. Scientific studies over the last several years have shown which environmental control measures are effective and which are not. The advice given here is based on those studies. By following a simple plan, you can significantly decrease your exposure to allergy-causing substances, and significantly improve your health. In some cases, exposure can be eliminated or decreased to the point that no other treatment is necessary. In other cases exposure can be decreased only partially, making other types of treatment necessary. But even in those situations, less treatment will be required, and it will work better if you have first decreased exposure. If an individual is allergic to one or more substances, the sum total of exposures at a given time (the total allergen load) determines whether or not the persons threshold has been reached and will cause symptoms..

Allergen immunotherapy is prescribed for patients with allergic rhinitis (nasal allergies or hay fever) who may or may not have asthma. Immunotherapy is given as injections under the skin or as rapidly dissolving tablets under the tongue (known as sublingual allergen immunotherapy or SLIT). Immunotherapy is the only medical treatment that can potentially cure or improve allergic disease long-term. In patients who have nasal allergies, injectable immunotherapy might prevent them from developing asthma. Research is ongoing to see if this holds true for SLIT as it is a newer form of immunotherapy.. SLIT is considered for long-term control of allergen- induced rhinitis with or without conjunctivitis when the symptoms are not adequately controlled by environmental control measures and/or medications.. SLIT is contraindicated in individuals with severe, unstable, or uncontrolled asthma. ...

A beautiful plasma image is a very artsy-craftsy thing and can stun and gratify the down-at-heel public at public exhibition. Scientifically, in the fusor biz, it contains no significant information related to the fusion process, nor is it a signature that fusion is even taking place! We now know that almost no fusion is taking place within it. It just a visible signature that electron orbitals are being messed with en-mass in their comings and goings in the level shift game ...

To further explore the composition and distribution of secondary organic aerosol (SOA) components from the photo-oxidation of light aromatic precursors (toluene, m-xylene, and 1,3,5-trimethylbenzene (1,3,5-TMB)) and idling gasoline exhaust, a vacuum ultraviolet photoionization mass spectrometer (VUV-PIMS) was employed. Peaks of the molecular ions of the SOA components with minimum molecular fragmentation were clearly observed from the mass spectra of SOA, through the application of soft ionization methods in VUV-PIMS. The experiments comparing the exhaust-SOA and light aromatic mixture-SOA showed that the observed distributions of almost all the predominant cluster ions in the exhaust-SOA were similar to that of the mixture-SOA. Based on the characterization experiments of SOA formed from individual light aromatic precursors, the SOA components with molecular weights of 98 and 110 amu observed in the exhaust-SOA resulted from the photo-oxidation of toluene and m-xylene; the components with a ...

The difference in the air pressure in your house and the outdoors can be negative or positive. Neither is particularly beneficial. Lets discuss negative air pressure as it relates to your home and specifically to your fireplace. Keep reading to see why this subject is important.
Atmospheric Pressure Chemical Ionisation (APCI) is an ionisation method used in mass spectrometry utilising gas-phase ion-molecule reactions at atmospheric pressure. Ionisation is effected using a corona discharge. This is a method of soft ionisation, where little fragmentation occurs in the source of the mass spectrometer.. Mass Spec uses APCI for trace analysis - primarily for drugs detection, but can be used for a wide range of other substances.. ...

Yet the results are contradictory. The objective of the present study was t
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.
Part I - Fluorinated Compounds A method has been developed for the extraction, concentration, and determination of two unique fluorinated compounds from the sediments of Lake Ontario. These compounds originated from a common industrial landfill, and have been carried to Lake Ontario by the Niagara River. Sediment samples from the Mississauga basin of Lake Ontario have been evaluated for these compounds and a depositional trend was established. The sediments were extracted by accelerated solvent extraction (ASE) and then underwent clean-up, fractionation, solvent exchange, and were concentrated by reduction under nitrogen gas. The concentrated extracts were analyzed by gas chromatography - electron capture negative ionization - mass spectrometry. The depositional profile determined here is reflective of the operation of the landfill and shows that these compounds are still found at concentrations well above background levels. These increased levels have been attributed to physical disturbances of ...
Electric field distributions and discharge properties of rod-rod contact electrodes were studied under the condition of DBD for the steady generation of atmospheric pressure glow discharge plasma (APGD) in air. We found that under the effect of the initial electrons generated in a nanometer-scale gap, the rod-rod cross-contact electrodes yielded APGD plasma in air. Regarding the rod-rod cross-contact electrodes, increasing the working voltage expanded the strong electric field area of the gas gap so that both discharge area and discharge power increased, and the increase in the number of contact points kept the initial discharge voltage unchanged and caused an increase in the plasma discharge area and discharge power. A mesh-like structure of cross-contact electrodes was designed and used to generate more APGD plasma, suggesting high applicability. ...

Atmospheric pressure chemical ionization (APCI) is an ionization method used in mass spectrometry which utilizes gas-phase ion-molecule reactions at atmospheric pressure (105 Pa), commonly coupled with high-performance liquid chromatography (HPLC). APCI is a soft ionization method similar to chemical ionization where primary ions are produced on a solvent spray. The main usage of APCI is for polar and relatively less polar thermally stable compounds with molecular weight less than 1500 Da. The application of APCI with HPLC has gained a large popularity in trace analysis detection such as steroids, pesticides and also in pharmacology for drug metabolites. A typical APCI usually consists of three main parts: a nebulizer probe which can be heated to 350-500oC, an ionization region with a corona discharge needle, and an ion-transfer region under intermediate pressure. The analyte in solution is introduced from a direct inlet probe or a liquid chromatography (LC) eluate into a pneumatic nebulizer ...
In 2004, the National Tree Seed Centre started collecting ash seed for genetic conservation.. Natural ash populations have adapted to their environments. Preserving germplasm from a significant number of these populations will facilitate the reintroduction of ash species once adequate environmental control measures for EAB are developed or trees resistant to the insect are bred and introduced. The easiest way to assemble breeding material is to collect seed from native stands. The seed will not transmit EAB to non-infested areas.. When properly handled and stored, ash seed will remain alive for many decades. Seed can be easily distributed to scientists and growers to produce seedlings for EAB research, breeding, genetics projects, other scientific study and future reintroduction efforts.. We encourage organizations as well as the general public to assist us in this effort by locating ash stands and populations and collecting seed to send to us.. To ensure the proper identification, collection ...

The Effect of Radio Frequency Discharge Plasma on Surface Properties and Biocompatibility of Polycaprolactone Matrices written by TPU researchers together with their colleagues from Kemerovo Research Institute for Complex Issues of Cardiovascular Diseases (NII KPSSZ) studies the effect of surface modification of bioresorbable polymer material (polycaprolactone, PCL) with abnormal glow discharge, initiated during radio-frequency magnetron sputtering of a hydroxyapatite target.. TPU scientists analyzed plasma exposure of PCL surface on bone marrow multipotent mesenchymal stromal cells behavior (BM MSCs). It was identified that modification of polymer surface with abnormal glow discharge stimulated adhesion and subsequent proliferation of BM MSCs. This type of plasma modification did not affect cell viability (apoptosis, necrosis). Thus, the surface modification with abnormal glow discharge, initiated during radio-frequency magnetron sputtering of a hydroxyapatite target, appeared to be a promising ...
Recently, hard X-ray high kinetic energy photoelectron spectroscopy has lead to a break-through due to its non destructive way of investigating the bulk electronic properties of materials. However, due to the relatively new development of this technique there is a lack of information concerning the photoionization cross sections at high energies. Whenever compound materials are investigated or when estimating signal levels and the feasibility of an electron spectroscopy experiment the knowledge of cross sections is essential. In the present work the experimentally determined relative sub-shell photoionization cross sections of shallow levels of nickel metal in the energy range of 2-9 keV will be shown. The data are compared with calculated sub-shell photoionization cross sections.. ...

TY - JOUR. T1 - Acid-base equilibria in aqueous solutions of 2-aminopurine radical cations generated by two-photon photoionization. AU - Shafirovich, Vladimir. AU - Dourandin, Alexander. AU - Luneva, Natalia P.. AU - Geacintov, Nicholas E.. PY - 2000/2. Y1 - 2000/2. N2 - The acid-base equilibria of the nucleic acid analogue 2-aminopurine (2AP) and 2-aminopurine riboside (2-APr) radicals generated by two-photon photoionization of the 2AP residues with intense 308 nm XeCl excimer laser pulses (fwhm = 12 ns, ca. 70 mJ cm-2 pulse-1) have been investigated using transient absorption spectroscopy techniques. It is of interest to investigate the properties of these radicals as a function of pH because of their abilities to undergo proton-coupled electron transfer reactions with other nucleic acid bases. Pronounced differences in the 2AP and 2APr radical absorption bands are observed in the 330-550 nm spectral region within the pH range of 1 to 12. These differences are attributed to the deprotonation ...
We report TOFMS investigations on the effects of hydrogen added to a dc GD argon plasma, in detail over the most likely concentration range occurring in analytical work (0-0.10% v/v), together with an overview to 0.8% v/v; typical GD-OES discharge conditions were used. Many previous studies on the effects of hydrogen in analytical GD-MS used much higher hydrogen concentrations. In this paper, we report for the first time the hydrogen effect on relative ion signal intensities of matrices, plasma and added gas, for very low but analytically important hydrogen concentrations. We investigate the behavior of doubly charged argon ions (Ar++), dimer ions (Cu2+, Fe2+, Ti2+, Ar2+) and polyatomic ions (ArH+, CuH+, FeH+, TiH+), which can play important roles in plasma processes. We discuss the probable discharge mechanisms in order to gain a greater understanding of the fundamental processes involved in the ionization of the species observed in this study and their likely effects on analytical results. ...
HORIBA Scientific novel Plasma Profiling TOFMS (PP-TOFMS) instrument provides the chemical composition as a function of depth of solid materials. This depth profiling technique consists of a glow discharge plasma source that erodes and ionizes sample material coupled to an ultra fast time of flight mass spectrometer.. High-throughput and universal depth profiling tool. The high ionic density of the glow discharge plasma results in a high sputtering rate. In addition the pre-analysis time is very much reduced as sample does not need to be transferred to a high vacuum chamber. As a result, sub-micron thin films can be analyzed in a few minutes.. The use of a radio frequency excitation signal allows analysis of all types of inorganic materials ranging from conductive to non-conductive (e.g. thin films on thick glass substrates). A quick sample preparation permits the analysis of coatings on flexible substrates.. High dynamic range. Mass Spectrometry coupled to a high intensity plasma source results ...

The results are presented of an intensive study of a railway tunnel environment under conditions of fully dieselized train traffic. Atmospheric sampling tests were conducted around the clock on an B-HR working shift basis for three days. More than 2000 observations were made to determine the fluctuations and range of occurrence of contaminant concentration under a variety of traffic conditions. There were no abnormal health effects on participants during exposure in the tunnel atmosphere, with the exception of minor cases of eye and throat irritation. However, nitrogen dioxide, aldehydes, smoke, and particulate matter attained high levels during periods of peak train activity. Therefore, installation of appropriate forced-draft ventilation is recommended for the tunnel before full dieselization is introduced to replace electrical operation of trains.. ...
Press release from Leeds University Study: New weapon to fight hospital infections - January 2, 2003 A potential new weapon in the fight against hospital acquired infections has been discovered by researchers at the University of Leeds. The scientists studied the effect of negative air ionizers on infections caused by acinetobacter; a pathogen responsible for increasing numbers of sometimes fatal infections amongst hospital patients. Ionizers were placed in the intensive care unit at St Jamess University Hospital, which, like similar wards across the UK, has had recurrent problems with infections caused by acinetobacter. For the first six months the researchers, from the aerobiological research group in the Universitys school of civil engineering, monitored the normal situation in the unit, taking samples from surfaces, patients and from the air to monitor bacteria levels, and logging the number of patient infections. During the second half of the year-long trial, the ionizers were switched ...
Theoretical analysis of the mechanism of action of chemical aerial disinfectants reveals that the rapid killing action which is obtained cannot be accounted for by a collision process between germicidal aerosol particles and the air-borne bacteria. However, a mechanism involving condensation of germicide molecules in the vapor state on to the bacteria-containing droplets results in a theoretical velocity of the correct order of magnitude.. Experimental tests of this theory show that pure germicide vapors free of aerosol droplets are almost instantly lethal to air-borne bacteria. Conversely, pure germicidal aerosols in the absence of vapor, had no effect on air-borne bacteria within 20 minutes or more. Therefore, it may be concluded on both theoretical and experimental grounds that rapid air sterilization requires the existence of the germicide in the vapor state.. ...

However, In order to better understand the roots of this movement, we need to take a step back and be introduced to a wonderful non-profit organization called Urban Farming. Triscuit partnered with Urban Farming to help support the construction of 65 community-based farms across the country. Urban Farming began with just 3 farms in Detroit, Michigan in 2005 and today they have created and planted the equivalent of 3,800 community and residential gardens across the globe. The organization sounds amazing to me.. It is for obvious reasons that big names, (like Ellen DeGeneres) and corporations want to get involved with Urban Farming; their message is so pure and heart felt. Through their work, Urban Farming encourages an awareness of diversity, community, non-violence, health, wellness, sustainable living, and education.. After discovering Urban Farming my attitude was warmed a bit towards Triscuits involvement. They are helping to spread community-based farms to 20 U.S urban centers and many to ...

Hi mum2000,. I dont have much experience of bosniak cysts either but my surgery for cancer was delayed for a few weeks as they were concerned about my potentially having sleep apnoea because of my weight. I was tested and found to have the condition and then had to successfully learn how to sleep using a variable positive air pressure machine that blows air into my lungs if I stop breathing when I sleep. I had to take the machine with me when I went for my surgery and was advised that rather than being taken to a surgical recovery ward after my operation I would be going to intensive care where I could be more closely monitored. I understand that the rationale behind this was that if I had breathing difficulties during the operation I could die very quickly whilst not operating on the kidney cancer it would take a number of years for it to become terminal.. As the cyst is classed as small and there are some concerns about your lungs it is likely to be similar concerns that are at work here. ...

The HR Del nova remnant was observed with the IFU-GMOS at Gemini North. The spatially resolved spectral data cube was used in the kinematic, morphological, and abundance analysis of the ejecta. The line maps show a very clumpy shell with two main symmetric structures. The first one is the outer part of the shell seen in Hα, which forms two rings projected in the sky plane. These ring structures correspond to a closed hourglass shape, first proposed by Harman & OBrien. The equatorial emission enhancement is caused by the superimposed hourglass structures in the line of sight. The second structure seen only in the [O III] and [N II] maps is located along the polar directions inside the hourglass structure. Abundance gradients between the polar caps and equatorial region were not found. However, the outer part of the shell seems to be less abundant in oxygen and nitrogen than the inner regions. Detailed 2.5-dimensional photoionization modeling of the three-dimensional shell was performed using the
