Conformations of Gly(n)H+ and Ala(n)H+ peptides in the gas phase. (1/1495)

High-resolution ion mobility measurements and molecular dynamics simulations have been used to probe the conformations of protonated polyglycine and polyalanine (Gly(n)H and Ala(n)H+, n = 3-20) in the gas phase. The measured collision integrals for both the polyglycine and the polyalanine peptides are consistent with a self-solvated globule conformation, where the peptide chain wraps around and solvates the charge located on the terminal amine. The conformations of the small peptides are governed entirely by self-solvation, whereas the larger ones have additional backbone hydrogen bonds. Helical conformations, which are stable for neutral Alan peptides, were not observed in the experiments. Molecular dynamics simulations for Ala(n)H+ peptides suggest that the charge destabilizes the helix, although several of the low energy conformations found in the simulations for the larger Ala(n)H+ peptides have small helical regions.  (+info)

Renal and hemodynamic effects of losartan in conscious dogs during controlled mechanical ventilation. (2/1495)

In 12 conscious dogs, we investigated whether the angiotensin II-receptor antagonist losartan increases renal sodium excretion and urine volume during controlled mechanical ventilation (CMV) with positive end-expiratory pressure. In four experimental protocols, the dogs were extracellular volume (ECV) expanded (electrolyte solution, 0.5 ml. kg-1. min-1 iv) or not and received losartan (100 micrograms. kg-1. min-1 iv) or not. They breathed spontaneously during the 1st and 4th hour and received CMV with positive end-expiratory pressure (mean airway pressure 20 cmH2O) during the 2nd and 3rd hours. In the expansion group, dogs with losartan excreted approximately 18% more sodium (69 +/- 7 vs. 38 +/- 5 micromol. min-1. kg-1) and 15% more urine during the 2 h of CMV because of a higher glomerular filtration rate (5.3 +/- 0.3 vs. 4.5 +/- 0.2 ml. min-1. kg-1) and the tubular effects of losartan. In the group without expansion, sodium excretion (2.0 +/- 0.6 vs. 2.6 +/- 1.0 micromol. min-1. kg-1) and glomerular filtration rate (3.8 +/- 0.3 vs. 3.8 +/- 0.4 ml. min-1. kg-1) did not change, and urine volume decreased similarly in both groups during CMV. Plasma vasopressin and aldosterone increased in both groups, and plasma renin activity increased from 4.9 +/- 0.7 to 7.8 +/- 1.3 ng ANG I. ml-1. h-1 during CMV in nonexpanded dogs without losartan. Mean arterial pressure decreased by 10 mmHg in nonexpanded dogs with losartan. In conclusion, losartan increases sodium excretion and urine volume during CMV if the ECV is expanded. If the ECV is not expanded, a decrease in mean arterial blood pressure and/or an increase in aldosterone and vasopressin during CMV attenuates the renal effects of losartan.  (+info)

Spike generation from dorsal roots and cutaneous afferents by hypoxia or hypercapnia in the rat in vivo. (3/1495)

The present study aimed at investigating the responsiveness of different parts of the primary afferent neurones to a brief hypoxia, hypercapnia or ischaemia under in vivo conditions. Action potentials were recorded in separate groups of anaesthetized rats from (i) the peripheral end of the central stump of the cut L3, L4 or L5 dorsal root (dorsal root preparation); (ii) the central end of the peripheral stump of the cut saphenous nerve (saphenous-receptor preparation); (iii) the distal end of a segment of the saphenous nerve cut at both ends (axon preparation). In paralysed animals interruption of artificial ventilation for 20-60 s elicited or increased the frequency of action potentials in both the dorsal root and saphenous-receptor preparations. Activation of these preparations was also achieved by inspiration of gas mixtures containing 10-0% oxygen (mixed with nitrogen) or 20-50% carbon dioxide (mixed with oxygen) which elicited in the blood a decrease in PO2 or an increase in PCO2 with a fall in pH. Occlusion of the femoral artery for 3 min also caused spike generation in the saphenous-receptor preparations with little alteration in blood pressure. All these stimuli failed to evoke action potentials in the axon preparations. Systemic (300 mg kg-1 s.c.) or perineural (2%) capsaicin pretreatment failed to inhibit the effect of hypoxia, hypercapnia or ischaemia, indicating a significant contribution of capsaicin-insensitive neurones to the responses. It is concluded that central and peripheral terminals but not axons of primary afferent neurones are excited by a brief hypoxia or hypercapnia and the peripheral terminals by a short local ischaemia as well. Excitation of central terminals by hypoxia or hypercapnia revealed in this way an antidromic activation of dorsal roots in response to natural chemical stimuli.  (+info)

Exercise gas transport determinants in elderly normotensive and hypertensive humans. (4/1495)

This study examined the effect of the phenylalkylamine calcium channel blocker verapamil, on resting left ventricular (LV) function and O2 uptake rate (VO2) during exercise at maximal and submaximal work rates. Nine older hypertensive (71 years; OH), 10 older sedentary normotensive (69 years; OS), 10 older active (71 years; OA) and 10 young (24 years; Y) individuals volunteered. Studies were completed in the control condition and 4-6 h following 240 mg verapamil SR per os. Resting LV systolic (fractional shortening; FS) and diastolic (early: late (E/A) flow velocity ratio and isovolumic relaxation time (IVRT) were measured by Doppler echocardiography. Maximal oxygen uptake (VO2,max) and, on subsequent test days, four transitions to and from a 6 min square wave exercise perturbation at a sub-anaerobic threshold intensity of 40 W (OH, OS, OA) or 100 W (Y) for determination of VO2 kinetics were performed on a cycle ergometer. Breath-by-breath VO2 transients were fitted with a monoexponential equation, starting at phase 2 of the response, while heart rate (HR) was fitted from phase 1, for the determination of the time constant of VO2 (tau VO2) and HR (tau HR). Baseline left ventricular FS was significantly greater in the OS (32%), OA (34%) and Y (34%) than in the OH (23%) groups, while E/A was significantly greater in the OA (1.16) and Y (2.34) than in the OH (0.9) and OS (0.82) groups (P < 0.05). Baseline VO2,max was higher and tau VO2 faster in the young (41.4 ml kg-1 min-1; 25.2 s) than in the older groups and in the OA (28.8 ml kg-1 min-1; 44.3 s) than in both OH (20.8 ml kg-1 min-1; 71.3 s) and OS (22.0 ml kg-1 min-1; 59.5 s) groups (P < 0.05). Heart rate kinetics showed similar differences to VO2 kinetics among the groups. After verapamil, no significant changes in FS, E/A or IVRT were observed in the OA and Y groups. In the OH group, FS (32%) and E/A (1.15) increased while IVRT decreased significantly (from 0.103 to 0.07; P < 0.05). In the OS group, only E/A increased significantly (0.82 to 1.0; P < 0.05). None of the exercise variables (VO2,max, tau VO2 or tau HR) were altered for the OA or Y groups. VO2,max increased (from 20.8 to 22.8 ml kg-1 min-1) in the OH and (from 22.0 to 24.1 ml kg-1 min-1) in the OS (P < 0.05). tau VO2 was accelerated from 71.3 to 49.2 s in the OH group and from 59.5 to 48.2 s in the OS group (P < 0.05). These results suggest that VO2 responses at maximal and submaximal work rates may be dependent upon the initial cardiac pump function of the study population.  (+info)

Development of in-vitro-derived bovine embryos cultured in 5% CO2 in air or in 5% O2, 5% CO2 and 90% N2. (5/1495)

To evaluate the effects of a three gas mixture of 5% O2, 5% CO2 and 90% N2 (OCN) on preimplantation embryo development, bovine in-vitro fertilization (IVF) oocytes were cultured in a defined medium (mBECM) with various supplements either under 5% CO2 in air or under OCN. When cultured in mBECM alone, embryo development was significantly stimulated in OCN compared to 5% CO2 in air (experiment 1). In the OCN atmosphere, blastocyst formation was further increased after addition of fetal bovine serum (FBS; 10%) or FBS + cumulus granulosa cells (CGC) to mBECM. The ratio of blastocysts to 8-cell embryos, number of hatched blastocysts and embryo diameter were markedly increased, and zona thickness was decreased after FBS addition. However, development up to the morula stage was fully supported by mBECM alone. There was no significant effect of beta-mercaptoethanol (ME; 10 microM) in OCN. In the 5% CO2 atmosphere, embryo development was significantly (P < 0.05) enhanced after addition of FBS + CGC + ME. In experiment 2, in OCN, FBS added at 60 h post-insemination was effective in stimulating blastocyst formation, but changes in medium volume per oocyte from 13.6 to 1.36 microliters had only a marginal effect. In conclusion, OCN gas mixture provides a suitable atmosphere for early embryo growth in vitro and mBECM + FBS in the optimal culture medium under this atmosphere.  (+info)

Theoretical calculations of glycine and alanine gas-phase acidities. (6/1495)

The gas-phase acidities of glycine and alanine were determined by using a variety of high level theoretical methods to establish which of these would give the best results with accessible computational efforts. MP2, MP4, QCISD, G2 ab initio procedures, hybrid Becke3-LYP (B3LYP) and gradient corrected Becke-Perdew (BP) and Perdew-Wang and Perdew (PWP) nonlocal density functionals were used for the calculations. A maximum deviation of approximately 13 and 18 kJ/mol from experimental data was observed for the computed delta Hacid and delta Gacid values, respectively. The best result was obtained at G2 level, but comparable reliability was reached when the considerably less time consuming B3LYP, BP, and PWP density functional approaches were employed.  (+info)

Elevation of blood pressure by genetic and pharmacological disruption of the ETB receptor in mice. (7/1495)

Exogenously administered endothelin (ET) elicits both pressor and depressor responses through the ETA and/or the ETB receptor on vascular smooth muscle cells and ETB on endothelial cells. To test whether ETB has pressor or depressor effects under basal physiological conditions, we determined arterial blood pressure (BP) in ETB-deficient mice obtained by crossing inbred mice heterozygous for targeted disruption of the ETB gene with mice homozygous for the piebald (s) mutation of the ETB gene (ETBs/s). F1 ETB-/s and ETB+/s progeny share an identical genetic background but have ETB levels that are approximately (1)/(8) and (5)/(8), respectively, of wild-type mice (ETB+/+). BP in ETB-/s mice was significantly higher, by approximately 20 mmHg, than that in ETB+/s or ETB+/+ mice. Immunoreactive ET-1 concentration in plasma as well as respiratory parameters was not different between ETB-/s and ETB+/s mice. A selective ETB antagonist, BQ-788, increased BP in ETB+/s and ETB+/+ but not in ETB-/s mice. Pretreatment with indomethacin, but not with NG-monomethyl-L-arginine, can attenuate the observed pressor response to BQ-788. The selective ETA antagonist BQ-123 did not ameliorate the increased BP in ETB-/s mice. Moreover, BP in mice heterozygous for targeted disruption of the ETA gene was not different from that in wild-type controls. These results suggest that endogenous ET elicits a depressor effect through ETB under basal conditions, in part through tonic production of prostaglandins, and not through secondary mechanisms involving respiratory control or clearance of circulating ET.  (+info)

Delayed ischemic preconditioning is mediated by opening of ATP-sensitive potassium channels in the rabbit heart. (8/1495)

Cardioprotection from preconditioning reappears 24 h after the initial stimulus. This phenomenon is called the second window of protection (SWOP). We hypothesized that opening of the ATP-sensitive potassium (KATP) channel mediates the protective effect of SWOP. Rabbits were preconditioned (PC) with four cycles of 5-min regional ischemia each followed by 10 min of reperfusion. Twenty-four hours later, the animals were subjected to sustained ischemia for 30 min followed by 180 min of reperfusion (I/R). Glibenclamide (Glib, 0.3 mg/kg ip) or 5-hydroxydecanoate (5-HD, 5 mg/kg iv) was used to block the KATP channel function. Infarct size was reduced from 41.2 +/- 2. 6% in sham-operated rabbits to 11.6 +/- 1.0% in PC rabbits, a 71% reduction (n = 11, P < 0.01). Treatment with Glib or 5-HD before I/R increased the infarct size to 43.4 +/- 2.6 and 37.8 +/- 1.9%, respectively (P < 0.01 vs. PC group, n = 12/group). Sham animals treated with either Glib or 5-HD had an infarct size of 39.0 +/- 3.4 and 37.8 +/- 1.5%, respectively, which was not different from control (40.0 +/- 3.8%) or sham (41.2 +/- 2.6%) I/R hearts. Monophasic action potential duration (APD) at 50% repolarization significantly shortened by 28.7, 26.6, and 23.3% in sham animals during 10, 20, and 30 min of ischemia. However, no further augmentation in the shortening of APD was observed in PC hearts. Glib and 5-HD significantly suppressed ischemia-induced epicardial APD shortening, suggesting that 5-HD may not be a selective blocker of the mitochondrial KATP channel in vivo. We conclude that SWOP is mediated by a KATP channel-sensitive mechanism that may have occurred because of the opening of the sarcolemmal KATP channel in vivo.  (+info)

The gas-phase acidities and proton affinities of analogs of protein amino acids were investigated. The gas-phase acidities of the lysine homologues were measured by the extended kinetic method in a quadrupole ion trap mass spectrometer. Deprotonation entropy changes were also measured. For ornithine, 2,4-diaminobutyric acid, and 2,3-diaminopropionic acid, the gas-phase acidities measured were 1416 ± 17 kJ/mol, 1420 ± 8 kJ/mol, and 1405 ± 24 kJ/mol. Their changes in entropy were measured to be -19 J/mol K, 1 J/mol k, and -24 J/mol K, respectively. The gas-phase acidities and entropies of two structural analogs of arginine, citrulline and canavanine, were measured by the extended kinetic method. The gas-phase acidity of citrulline was measured to be 1366 ± 11 kJ/mol, and the gas-phase acidity of canavanine was measured to be 1401 ± 13 kJ/mol. The proton affinity and protonation entropy change for citrulline was measured as well. The proton affinity was determined to be 984 ± 11 kJ/mol with an
Structural characterization of ions in the gas phase is facilitated by measurement of ion collision cross sections (CCS) using techniques such as ion mobility spectrometry. Further information is gained from CCS measurement when comparison is made between measurements and accurately predicted CCSs for model ion structures and the gas in which measurements are made. While diatomic gases, namely molecular nitrogen and air, are being used in CCS measurement with increasingly prevalency, the majority of studies in which measurements are compared to predictions use models in which gas molecules are spherical or non-rotating, which is not necessarily appropriate for diatomic gases. Here, we adapt a momentum transfer based CCS calculation approach to consider rotating, diatomic gas molecule collisions with polyatomic ions, and compare CCS predictions with a diatomic gas molecule to those made with a spherical gas molecular for model spherical ions, tetra-alkylammonium ions, and multiply charged ...
Male pattern baldness (MPB), an observable trait, has been reported to be associated with various diseases, such as prostate cancer and cardiovascular disease. Oral sulfur-containing gases have also been suggested to be useful as markers of systemic health condition. However, there are no known reports regarding the associations among MPB, and oral sulfur-containing gases, and systemic health conditions in males. We studied 170 male subjects aged either 60 or 65 years old. The degree of MPB was assessed using the Norwood-Hamilton Baldness scale. Oral sulfur-containing gases were measured using a compact-designed device. All subjects completed physical and laboratory blood examinations, a face-to-face medical questionnaire, and an oral examination. There were significant differences between the levels of CH3SCH3 and baldness patterns, independent of age. When we analyzed whether the association was linked to systemic health condition, a strong significant association was observed between the level of

We present a high-level theoretical study on the gas-phase reaction between formaldehyde and hydroperoxyl radical carried out using the DFT-B3LYP, QCISD, and CCSD(T) theoretical approaches in connection with the 6-311+G(d,p), 6-311+G(2df,2p), and aug-cc-pVTZ basis sets. The most favorable reaction path begins with the formation of a pre-reactive complex and produces the peroxy radical CH2(OO)OH in a process that is computed to be exothermic by 16.8 kcal/mol. This reaction involves a process in which the oxygen terminal of the HO2 moiety adds to the carbon of formaldehyde, and, simultaneously, the hydrogen of the hydroperoxyl group is transferred to the oxygen of the carbonyl in a proton-coupled electron-transfer mechanism. Our calculations show that this transition state lies below the sum of the energy of the reactants, and we computed a rate constant at 300 K of 9.29 × 10-14 cm3 molecule-1 s-1, which is in good agreement with the experimental results. Also of interest in combustion chemistry, ...

N2 - The stereoselectivities for hydrogen abstraction in the electron impact induced loss of acetic acid from three 1,2-disubstituted ethyl acetates as well as the loss of water from three acyclic secondary alcohols have been determined. This information was sought in an attempt to (1) help define the general limits for conformational analysis in the study of gas-phase ions and (2) determine the structural relationships, fundamental to conformation, among the various gas-phase ions and accessible phase molecules studied. In each case, i.e., elimination of acetic acid and loss of water, the results are stereochemically comparable to the analogous thermal reactions, i.e., formation of olefins from the pyrolysis of the subject acetates and 1,4-hydrogen abstraction by the alkoxy radicals derived from the alcohols ...

Due to the existence of numerous isomers, the in-depth analysis of glycans represents a major challenge. Currently, the majority of glycans are analysed using mass spectrometry (MS)-based techniques, which can provide information on regioisomers but usually fail to differentiate stereoisomers. A promising approach to overcome this limitation is to implement ion mobility spectrometry (IMS) as an additional gas-phase separation dimension. This review highlights recent developments in which IM-MS was used as a tool for comprehensive glycan analysis or as rapid screening method for glycan feature analysis. Furthermore, we summarize a series of very recent investigations in which gas-phase spectroscopy is applied to study glycans and discuss the potential of the hyphenation between IM-MS and infrared (IR) spectroscopy as a future tool for glycomics and glycoproteomics. ...

In an article in the December 2003 issue of Gut, Eamonn Quigley, MD, discusses the role of intestinal gas in IBS and its relationship to IBS symptoms. Patients with IBS do not appear to produce more gas than do individuals not suffering from IBS. They do appear, however, to suffer from abnormal gas transit, which result in gas retention in the small intestine. This gas retention, combined with visceral hypersensitivity, is likely to cause symptoms (ie, gas retention causes bloating and distension, whereas hypersensitivity causes patients with IBS to experience greater discomfort than is experienced by persons without IBS at the same level of retention). Gas content and transit appear to conspire with the motor and sensory responses of the gut to produce gas-related symptoms in patients with IBS as well as in individuals not suffering from IBS, according to Dr. Quigley ...

In other instances, molecular interactions between gas molecules previously adsorbed on a solid surface form significant interactions with gas molecules in the gaseous phases. Hence, adsorption of gas molecules to the surface is more likely to occur around gas molecules that are already present on the solid surface, rendering the Langmuir adsorption isotherm ineffective for the purposes of modelling. This effect was studied in a system where nitrogen was the adsorbate and tungsten was the adsorbent by Paul Kisliuk (1922-2008) in 1957.[10] To compensate for the increased probability of adsorption occurring around molecules present on the substrate surface, Kisliuk developed the precursor state theory, whereby molecules would enter a precursor state at the interface between the solid adsorbent and adsorbate in the gaseous phase. From here, adsorbate molecules would either adsorb to the adsorbent or desorb into the gaseous phase. The probability of adsorption occurring from the precursor state is ...
Abstract: Samples of unfractionated forage, isolated NDF and residue insoluble in 90% Ethanol were fermented in vitro and gas production was monitored. The gas volume associated with the ethanol soluble (A fraction) was determined as the difference between the gas from the whole forage and from the ethanol residue.The gas yield associated with the fraction insoluble in 90% ethanol but soluble in neutral detergent soluble (B1 fraction) was determined by subtracting the isolated NDF gas curve from the corresponding ethanol residue curve. This experiment included untreated Corn Silage (CS) and chemically treated corn silage. The rate of gas formation from the A fraction was approximately rather than (p,0.05) the B1 fraction. The gas production of A fraction was less than (p,0.05) the B1 fraction. The CS was treated with urea (10g kg-1) or formaldehyde (4g kg-1). Cumulative gas production was recorded at 2, 4, 8, 12, 16, 24, 36, 48, 72 and 96 h of incubation and McDonald equation was used to ...

The functions of some gas vesicle genes are conserved between species and have been well characterized, such as and sp. ATCC 39006 cell. Gas vesicles increase the buoyancy of cells and, when present in sufficient quantity, facilitate upward flotation in static water columns [3]. Gas vesicles collapse when exposed to pressure that exceeds ...
An inert gas is a gas which does not undergo chemical reactions under a set of given conditions. The noble gases often do not react with many substances, and were historically referred to as the inert gases. Inert gases are used generally to avoid unwanted chemical reactions degrading a sample. These undesirable chemical reactions are often oxidation and hydrolysis reactions with the oxygen and moisture in air. The term inert gas is context-dependent because several of the noble gases can be made to react under certain conditions. Purified argon and nitrogen gases are most commonly used as inert gases due to their high natural abundance (78% N2, 1% Ar in air) and low relative cost. Unlike noble gases, an inert gas is not necessarily elemental and is often a compound gas. Like the noble gases the tendency for non-reactivity is due to the valence, the outermost electron shell, being complete in all the inert gases. This is a tendency, not a rule, as noble gases and other inert gases can react to ...
Major ion chemistry and dissolved inorganic carbon system (DIC, mainly HCO3- and gaseous CO2) in the Luodingjiang River, a mountainous tributary of the Zhujiang (Pearl River), China, were examined based on a seasonal and spatial sampling scheme in 2005. The diverse distribution of lithology and anthropogenic impacts in the river basin provided the basic idea to assess the effects of lithology vs. human activities on water chemistry and carbon biogeochemistry in river systems. Major ions showed great spatial variations, with higher concentrations of total dissolved solids (TDS) and DIC in the regions with carbonate rocks and clastic sedimentary rocks, while lower in the regions with metamorphic sandstones and schists as well as granites. pCO2 at all sampling sites was oversaturated in June, ranging with a factor from 1.6 to 18.8 of the atmospheric concentration, reflecting the enhanced contribution from baseflow and interflow influx as well as in situ oxidation of organic matter. However, in ...
CVD is a thermal process because a certain thermal energy is needed to decompose the gas precursors and reassemble them in the material to be deposited. Processing conditions in a CVD should avoid gas-phase reactions (homogenous deposition) and should favor that the deposited layer is assembled in the substrate as a surface process (heterogeneous deposition). This can be achieved at atmospheric pressure (APCVD) by heavily diluting the active gases. When these gaseous precursors are let to react in a rarefied the process is termed Low Pressure CVD (LPCVD). The partial vacuum avoids gas-phase reactions. The low pressure also favors larger diffusivity of the species so that an LPCVD process can decorate cavities and led to conformal coatings when a topography is present. The conformality is also spurred by the process temperature which favors movement of the species along the surface. Pressures are usually in the millitorr-torr range and temperatures range from 400-800C (depending on the energy ...
This is because the ignition systems are general purpose devices used in Class 1 Zone 2 areas.

For some reason, reactor1 gets heated up once Tepco stops nitrogen gas injection.. In order to purge hydrogen gas that may cause hydrogen gas explosion, Tepco is injecting nitrogen gas into reactor1.. However, it also causes radioactive material to leak out of the vessel, so Tepco decreased the nitrogen gas volume to inject to reactor1 RPV by 20% on 10/9/2013 as an attempt.. 26 hours later, they observed the temperature rise by approx. 8℃. Having this increase, they increased the nitrogen gas volume to inject to PCV by 4%, but its still stably high.. Tepco announced they are not injecting liquid nitrogen as air-cooling, but the relationship between nitrogen gas injection and reactor temperature hasnt been identified.. ...
Inert gas is produced on board crude oil carriers (above 8,000 tonnes)(from Jan 1, 2016) by using either a flue gas system or by burning kerosene in a dedicated inert gas generator. The inert gas system is used to prevent the atmosphere in cargo tanks or bunkers from coming into the explosive range.[6] Inert gases keep the oxygen content of the tank atmosphere below 5% (on crude carriers, less for product carriers and gas tankers), thus making any air/hydrocarbon gas mixture in the tank too rich (too high a fuel to oxygen ratio) to ignite. Inert gases are most important during discharging and during the ballast voyage when more hydrocarbon vapor is likely to be present in the tank atmosphere. Inert gas can also be used to purge the tank of the volatile atmosphere in preparation for gas freeing - replacing the atmosphere with breathable air - or vice versa. The flue gas system uses the boiler exhaust as its source, so it is important that the fuel/air ratio in the boiler burners is properly ...
A hybrid structure gas sensor of reduced graphene oxide (RGO) decorated graphene (RGO-Gr) is designed for ultra-low concentration ammonia detection. The resistance value of the RGO-Gr hybrid is the indicator of the ammonia concentration and controlled by effective charge transport from RGO to graphene after ammonia molecule adsorption. In this hybrid material, RGO is the adsorbing layer to catch ammonia molecules and graphene is the conductive layer to effectively enhance charge/electron transport. Compared to a RGO gas sensor, the signal-to-noise ratio (SNR) of the RGO-Gr is increased from 22 to 1008. Meanwhile, the response of the RGO-Gr gas sensor is better than that of either a pristine graphene or RGO gas sensor. It is found that the RGO reduction time is related to the content of functional groups that directly reflect on the gas sensing properties of the sensor. The RGO-Gr gas sensor with 10 min reduction time has the best gas sensing properties in this type of sensor. The highest sensitivity is

Hydrocarbon gas in a sample is measured by a double beam detector responding to the transmission of absorption properties of the gas in response to applied radiation from a laser source. Monochromatic light from the laser source is split into two radiation beams, a sample path beam and a reference path beam, and directed to a radiation detector which sequentially responds to the reference energy and the sample energy. A difference in the absorption by the sample path energy with respect to the reference path energy produces two, different level, output signals from the detector. The sample energy signal and reference energy signal are respectively directed to a sample channel circuit and a reference channel circuit. Outputs from the individual circuits are amplified logarithmically and applied to inputs of a differential amplifier wherein the ratio of the sample signal to the reference signal produces a voltage for actuating a meter indicator. For a hydrocarbon gas content in a sample in excess of a

Hydrocarbon gases, primarily methane but also the c2 through c5 paraffins, the c2 and c3 olefins, and possibly the c4 and c5 olefins, are byproducts of coal formation. Although it is generally believed that coal formation occurred at temperatures below 200 deg c, most experimental work on gas formation from coal has been performed at temperatures between 200 deg and 1,000 deg c. The objective of
We report here the generation of gas-phase complexes containing Pd(II), a ligand (deprotonated alanine, A-), and/or N-terminus derivatized peptides containing histidine as one of the amino acids. The species were produced by electrospray ionization, and their gas-phase reactions were investigated using ion-trap tandem mass spectrometry. Pd(II) forms a stable diaqua complex in the gas phase of the formula, [Pd(A-) (H(2)O)(2)]+, (where A- = deprotonated alanine) along with ternary complexes containing A- and peptide. The collision-induced dissociation (CID) patterns of the binary and ternary complexes were investigated, and the dissociation patterns for the ternary complexes suggest that: (a) the imidazole ring of the histidine side group may be the intrinsic binding site of the metal ion, and (b) the peptides fragment primarily by cleavage of the amide bond to the C-terminal side of the histidine residues. These observations are in accord with previous solution-state studies in which Pd(II) was ...

Recovery of hydrocarbon gas in micro-Darcy rock is now becoming more common-place for gas producers. As part of the reservoir characterization associated with these systems, it is required to understand parameters such as the total porosity and permeability of the system, but also the initial water saturation and the effective gas permeability at this connate water saturation. This is still under the realm of what is termed routine core analysis, but in these tight formations it is imperative to understand that these tests are actually very non-routine by nature. Current work presents a case study of core analysis that was run on plugs from a tight gas producing formation, and illustrates some of the pitfalls and corrections associated with measurements of this low permeability rock. The case study combines low field NMR measurements with core flooding measurements of porosity and permeability. Cores are initially tested at their connate water saturations: NMR measures the initial water ...

To date, no targeted therapeutic treatments for the ongoing COVID-19 outbreak have been identified. Antiviral combined with adjuvant therapies are currently under investigation. The clinical spectrum of the infection is wide, ranging from mild signs of upper respiratory tract infection to severe pneumonia and death.. In the patients who progress, the time period from symptoms onset to development of dyspnea is reported to be between 5 to 10 days, and that one to severe respiratory distress syndrome from 10 to 14 days. Globally, 15 to 18% of patients deteriorates to the need of mechanical ventilation, despite the use of non-invasive ventilatory support in the earliest phases of the disease. Probability of progression to end stage disease is unpredictable, with the majority of these patients dying from multi-organ failure. Preventing progression in spontaneously breathing patients with mild to moderate disease would translate in improved morbidity and mortality and in a lower use of limited ...
Among them, irritant gases include chlorine, phosgene, diphosgene, sulfur dioxide, nitrogen oxides, formaldehyde, ammonia, and ozone. The action of irritating gases on the body is characterized by a strong irritant effect on the skin and mucous membranes, some of which also have a strong corrosive effect. The degree of damage to the body by irritating gases is related to its solubility in the water and the site of action. In general, water-soluble chemicals, such as chlorine, ammonia, and sulfur dioxide, rapidly stimulate the eyes and upper respiratory tract, causing eye and upper respiratory tract irritation; and water-soluble chemicals such as light. Gas, nitrogen dioxide, and other effects on the lower respiratory tract and alveoli are more obvious. The severity of lesions caused by irritant gases, in addition to the nature of the chemical itself, is most closely related to the concentration and timing of exposure to chemicals.

The gas condenser-GC/MS analysis identified concentrations of 56 VOCs in the breath exhaled by the test population of 136 volunteers (107 patients with lung cancer and 29 controls), and selected four target VOCs, nonanal, acetoin, acetic acid, and propanoic acid, for use with the condenser, GC, and sensor-type prototype system. The prototype system analyzed exhaled breath samples from 101 volunteers (74 patients with lung cancer and 27 controls). The prototype system exhibited a level of performance similar to that of the gas condenser-GC/MS system for breath analysis.

Introduction. Animal/Plant Gas Exchange Our planet is lively in many ways. Everything on Earth is part of one system, so Gas Exchange could be discussed under Cycles, Interliving, or under Balance. Everything really is connected to everything else. Every living organism must exchange gases to stay alive. We each take in a gas (breathing) we need from the atmosphere, use it to make food or transform food, and release the leftover part of the gas, which the living cells have chemically changed into a different gas. Animals take in oxygen gas, transfer it to their blood, and carry it to every cell, where it is used to transform food into energy, where carbon dioxide gas is created as a by-product or leftover. more. Middle. The diagram below show the circle of gas exchange between photosynthetic life and animal life. Giving/Receiving: Gas Exchange is a system of Giving. Plants give oxygen to animals (including you), and animals give carbon dioxide to plants. Gas Exchange is also a system of ...
MUCHACHAS experiments were carefully designed to separate initial SOA formation from subsequent exposure to OH radicals in an aging step, and to ensure that substantial concentrations of OH were produced during that step. The results confirm dramatic aging effects and strongly suggest that the major effect of gas-phase OH reactions is to enhance SOA concentrations by a factor of 2-4 (Fig. 1B). The fundamental result is that gas-phase reactions of semivolatile SOA vapors are clearly an important part of OA evolution, and these experiments substantially extend the timescale of the chamber studies.. Model-measurement agreement varies between experiments. It is best for the AIDA and PSI experiments, with the highest and most intense OH exposure relative to wall losses. The fresh SOA prediction (t ≤ 0 in Fig. 2) is based on the scavenger-free SOA mass yields in Fig. 1A (40). SOA production is known to vary with conditions [VOC∶NOx, UV light, etc. (4)] that were not kept constant in different ...
micro carbon monoxide Gas Concentration 160 Detector.Product description. Item Number: BWGAMIC3M The Gas Alert Micro 3 is perfect for home and building inspectors. It allows the advantage of protection without the liability of having to inspect and locate every potential gas leak. By approaching gas detection from a safety standpoint rather than leak detection, inspectors can reduce their liability without sacrificing safety.
The sum of these two frequencies is the cyclotron frequency, which depends only on the ratio of electric charge to mass and on the strength of the magnetic field. This frequency can be measured very accurately and can be used to measure the masses of charged particles. Many of the highest-precision mass measurements (masses of the electron, proton, 2H, 20Ne and 28Si) come from Penning traps. Buffer gas cooling, resistive cooling, and laser cooling are techniques to remove energy from ions in a Penning trap. Buffer gas cooling relies on collisions between the ions and neutral gas molecules that bring the ion energy closer to the energy of the gas molecules. In resistive cooling, moving image charges in the electrodes are made to do work through an external resistor, effectively removing energy from the ions. Laser cooling can be used to remove energy from some kinds of ions in Penning traps. This technique requires ions with an appropriate electronic structure. Radiative cooling is the process by ...
Intestinal gas is best explained by dividing the subject into upper intestinal gas and lower intestinal gas. Upper intestinal gas consists primarily of swallowed air & lower intestinal gas is produced normally by the fermentation of undigested complex sugars.

At the end of the 1970s, WITT pioneered the development of gas mixing systems and was the first company to offer a gas mixer for modified atmosphere packaging. For the first time, users were able to create the specific gas mixtures they required. The use of gas mixers offers several benefits compared to pre-mixed gases. Gas mixers create high quality gas mixtures without strata. Furthermore, they offer highest flexibility in terms of mixing ratios and flow rates at the point of use, and ensure the most economic use of the component gases. To this day, the heart of many WITT gas mixers is the mechanical proportional mixing valve. This enables the reliable creation of gas mixtures from almost all technical gases - precisely and stably. The valve has 2 gas inlets and one outlet for the mixture. Adjustment of the valve in turn engages the orifice and piston to proportionally regulate the flow rate of the individual gases to create the required gas mixture. Using all of its know-how, WITT offers the ...
