Exposure of medical personnel to methylmethacrylate vapor during percutaneous vertebroplasty. (1/834)

The occupational exposure to methylmethacrylate (MMA) vapor during percutaneous vertebroplasty was determined. During five vertebroplasty procedures, air-sampling pumps were attached to medical personnel. MMA vapor levels in the samples were then quantified using gas chromatography. The samples collected yielded MMA vapor levels of less than five parts per million (ppm). The MMA vapor concentrations measured were well below the recommended maximum exposure of 100 ppm over the course of an 8-hour workday.  (+info)

Characterization of inhaled alpha-methylstyrene vapor toxicity for B6C3F1 mice and F344 rats. (2/834)

alpha-Methylstyrene (AMS) is a chemical intermediate used in the synthesis of specialty polymers and copolymers. Inhalation studies of AMS were conducted because of the lack of toxicity data and the structural similarity of AMS to styrene, a toxic and potentially carcinogenic chemical. Male and female B6C3F1 mice were exposed to 0, 600, 800, or 1000 ppm AMS 6 h/day, 5 days/week, for 12 days. After 1 exposure, 21% (5/24) of female mice were found dead in the 1000-ppm group, 56% (10/18) in the 800-ppm group, and 6% (1/18) in the 600-ppm concentration group. After 12 exposures, relative liver weights were significantly increased and relative spleen weights were significantly decreased in both male and female mice at all concentrations. No microscopic treatment-related lesions were observed. A decrease in hepatic glutathione (GSH) was associated with AMS exposure for 1 and 5 days. Male and female F344 rats were exposed to 0, 600 or 1000 ppm AMS for 12 days. No mortality or sedation occurred in AMS-exposed rats. Relative liver weights were significantly increased in both males and females after 12 exposures to 600 or 1000 ppm. An increased hyaline droplet accumulation was detected in male rats in both concentration groups; no significant microscopic lesions were observed in other tissues examined. Exposure of male and female F344 rats and male NBR rats to 0, 125, 250 or 500 ppm AMS, 6 h/day for 9 days resulted in increased accumulation of hyaline droplets in the renal tubules of male F344 rats in the 250 and 500 ppm concentration groups. Although AMS and styrene are structurally very similar, AMS was considerably less toxic for mice and more toxic for male rats than styrene.  (+info)

Quantitative analysis of styrene monomer in polystyrene and foods including some preliminary studies of the uptake and pharmacodynamics of the monomer in rats. (3/834)

A variety of food containers, drinking cups and cutlery, fabricated from polystyrene (PS) or polystyrene-related plastic, were analyzed for their styrene monomer content. Samples of yogurt, packaged in PS cups, were similarly analyzed and the leaching of styrene monomer from PS containers by some food simulants was also determined. Blood level studies with rats, dosed with styrene monomer by various routes, illustrated uptake phenomena that were dependent on the dose and route of administration and were also affected by the vehicle used to convey the styrene monomer.  (+info)

Dose-dependent fate of vinyl chloride and its possible relationship to oncogenicity in rats. (4/834)

Studies on the fate of 14C-labeled vinyl chloride (VC) following oral administration and inhalation exposure in rats demonstrated that the disposition of VC in the body is a function of the dose. More importantly, from the data available, it appears that a correlation exists between doses of VC which cause tumors and those that saturate metabolic or detoxifying pathways. Additional studies characterized the depression of liver non-protein sulfhydryl content (primarily GSH) with the duration and concentration of exposure to VC. The results of these investigations indicate that statistical projections utilizing data collected from rats exposed to high doses of VC are invalid for predicting the hazard of low level exposure, because such projections violate a priori assumption that the dynamics governing the fate of VC in the body are unaltered.  (+info)

Health aspects of the curing of synthetic rubbers. (5/834)

A commonly used tread rubber formulation was cured in the laboratory under conditions simulating vulcanization in the Bag-O-Matic press. Volatile emissions were collected on charcoal and analyzed by combined GC-mass spectrometry. The compounds identified were either contaminants present in the raw material or reaction products. Some of these compounds were also identified in charcoal tube samples collected in the atmosphere of the industrial operations. Estimates based on the loss of weight of rubber during curing were used to predict airborne concentrations and compared to the concentrations actually found. The literature of the toxicity of raw materials and effluents was reviewed, and no acute or chronic toxicological effects would be anticipated. Information concerning potential carcinogenicity was not available and could not be evaluated.  (+info)

Transurethral prostate vaporization using an oval electrode in 82 cases of benign prostatic hyperplasia. (6/834)

OBJECTIVE: To present our initial experience in transurethral vaporization of the prostate (TVP) using an oval electrode for the treatment of benign prostatic hyperplasia (BPH). METHODS: A total of 82 patients underwent TVP procedures with the oval electrode. The newly designed oval-shaped electrode can work with a High Frequency Electrosurgery Unit. Prostate gland tissue was vaporized through an Fr 24 percutaneous nephroscope transurethrally. The operation procedure was similar to transurethral resection of the prostate (TURP) or transurethral laser prostatectomy (TULP). Power setting ranged from 240 W to 320 W. Local vaporization temperature reached 120 degrees C. RESULTS: Urination was recovered in all 82 patients after TVP. Mean post-treatment International Prostate Symptom Score (I-PSS) reduced from 27.10 to 5.05; mean bladder residual urine volume dropped from 147.71 ml to 33.2 ml; and mean urine flow rate (MFR) increased from 4.45 ml/s to 14.57 ml/s (P < 0.01). The initial results of short-term follow-up were excellent. CONCLUSIONS: TVP with the oval electrode is easy to perform and causes less hemorrhage and few complications. It especially benefits elderly and/or critically-ill patients. We believe that TVP with our oval electrode is feasible with low risk.  (+info)

Estimation of the dermal absorption of m-xylene vapor in humans using breath sampling and physiologically based pharmacokinetic analysis. (7/834)

A physiologically-based pharmacokinetic model, containing a skin compartment, was derived and used to simulate experimentally determined exposure to m-xylene, using human volunteers exposed under controlled conditions. Biological monitoring was conducted by sampling, in exhaled alveolar air and blood, m-xylene and urinary methyl hippuric acid concentrations. The dermal absorption of m-xylene vapor was successfully and conveniently studied using a breath sampling technique, and the contribution to m-xylene body burden from the dermal route of exposure was estimated to be 1.8%. The model was used to investigate the protection afforded by an air-fed, half-face mask. By iteratively changing the dermal exposure concentration, it was possible to predict the ambient concentration that was required to deliver the observed urinary excretion of methylhippuric acid, during and following inhalation exposure to 50 ppm m-xylene vapor. This latter extrapolation demonstrates how physiologically-based pharmacokinetic modeling can be applied in a practical and occupationally relevant way, and permitted a further step not possible with biological monitoring alone. The ability of the model to extrapolate an ambient exposure concentration was dependent upon human metabolism data, thereby demonstrating the mechanistic toxicological basis of model output. The methyl hydroxylation of m-xylene is catalyzed by the hepatic mixed function oxidase enzyme, cytochrome P450 2E1 and is active in the occupationally relevant, (<100 ppm) exposure range of m-xylene. The use of a scaled-up in vitro maximum rate of metabolism (Vmaxc) in the model also demonstrates the increasingly valuable potential utility of biokinetic data determined using alternative, non-animal methods in human chemical-risk assessment.  (+info)

Environmental exposure to volatile organic compounds among workers in Mexico City as assessed by personal monitors and blood concentrations. (8/834)

Benzene, an important component in gasoline, is a widely distributed environmental contaminant that has been linked to known health effects in animals and humans, including leukemia. In Mexico City, environmental benzene levels, which may be elevated because of the heavy traffic and the poor emission control devices of older vehicles, may pose a health risk to the population. To assess the potential risk, portable passive monitors and blood concentrations were used to survey three different occupational groups in Mexico City. Passive monitors measured the personal exposure of 45 workers to benzene, ethylbenzene, toluene, o-xylene and m-/p-xylene during a work shift. Blood concentrations of the above volatile organic compounds (VOCs), methyl tert-butyl ether, and styrene were measured at the beginning and the end of a work shift. Passive monitors showed significantly higher (p > 0.0001) benzene exposure levels among service station attendants (median = 330 microg/m3; range 130-770) as compared to street vendors (median = 62 microg/m3; range 49-180) and office workers (median = 44 microg/m3, range 32-67). Baseline blood benzene levels (BBLs) for these groups were higher than those reported for similar populations from Western countries (median = 0.63 microg/L, n = 24 for service station attendants; median = 0.30 microg/L, n = 6 for street vendors; and median = 0.17 microgr;g/L, n = 7 for office workers). Nonsmoking office workers who were nonoccupationally exposed to VOCs had BBLs that were more than five times higher than those observed in a nonsmoking U.S. population. BBLs of participants did not increase during the work shift, suggesting that because the participants were chronically exposed to benzene, complex pharmacokinetic mechanisms were involved. Our results highlight the need for more complete studies to assess the potential benefits of setting environmental standards for benzene and other VOCs in Mexico.  (+info)

The fate and transport of nitrogen compounds in urea-fertilized soils has historically been a topic of great interest. At present, several models exists for simulating the various transformations involved. A major constraint in the application of these models is the assignment of numerical values to the coefficients that quantify these transformations. This study attempts to characterize the processes linked to the hydrolysis of urea, adsorption and volatilization of ammonia, and nitrification in agricultural soils. We followed the temporal sequence of volatilization of ammonia in two different soils fertilized with urea under controlled conditions in the laboratory. The amounts of nitrate and ammonia in soil were also measured at the end of each trial. Several modeling alternatives were analyzed in order to accurately reproduce the results. Among these alternatives, the most successful approaches included the kinetics of urea hydrolysis and ammonia adsorption and desorption processes. Urea ...

A study was set up to investigate the environmental effects of anaerobic digestion and separa-tion of slurry. Volatilisation of odour and ammonia from treated and untreated slurry were compared both during storage and following land application. It was found that ammonia volatilisation was higher from uncovered stores of anaerobically digested and separated slurry than from untreated slurry, however, when slurry stores were covered efficiently, the loss rate was low and equal for treated and untreated slurry. Ammonia volatilisation following land application was found to be lower from both anaerobically digested and separated slurry compared to untreated slurry. Treatment of slurry by anaerobic digestion and separation did not reduce odour nuisances during storage, however, odour nuisance from slurry stores was found to be efficiently reduced by an artificial crust cover of the slurry stores. During land application the odour nuisances were found to be lower for anaerobically digested and ...

Thermodynamics of vaporization of 3-isopropylbiphenyl. to an equation on temperature dependence of vaporization enthalpies // Journal of Thermal Analysis and Calorimetry. - 2015. - Vol. 120, no. 2. - P. 1375-1381. Abstract Enthalpies of vaporization,ΔglH∘m,were determined for 3-isopropylbiphenyl in the temperature range from 323 to 373 K. Measurements were performed on an isothermal heat conducting Calvet microcalorimeter according to the standard procedure with an estimated accuracy of 0.7 per cent. The average values of the standard enthalpies of vaporization were adjusted to 298.15 K. The latter has been used to calculate the standard formation enthalpy for 3-isopropylbiphenyl in the gaseous state. A second-order group additivity method has been applied to predict the vaporization enthalpies of some cyclic compounds. The contributions of tert-butyl, methyl, and isopropyl group to the vaporization enthalpies of the aromatic hydrocarbon derivatives are ...

Common Questions at Vapor Intrusion Sites: Minnesota Dept. of HealthCommon Questions at Vapor Intrusion Sites: Minnesota Dept. of Health
Contaminants in indoor air resulting from vapor intrusion are often estimated using the concentrations in a sub-slab sample multiplied by an attenuation factor (AF). An AF accounts for the reduction in concentration that occurs when vapors enter a building and mix with indoor air. The Minnesota Pollution Control Agency (MPCA) is using a very protective AF of 0.1, (or 10% of the soil vapor found in the sub-slab will be in indoor air). The amount of soil vapor that enters a building is different for every building, but this AF overestimates indoor air concentrations in most homes.. EPA recently recommended an AF of 0.03 for screening sub-slab soil vapor at vapor intrusion sites throughout the U.S. (USEPA, 2015). EPA derived the AF of 0.03 after looking at data from numerous homes across the country. 95 percent of the homes studied had (basement) indoor air concentrations less than or equal to 0.03 times the sub-slab concentration, and 50 percent of the homes had (basement) indoor air ...

Annual and Seasonal Mean Net Evaporation Rates of the Red Sea Water during Jan 1958 - Dec 2007Annual and Seasonal Mean Net Evaporation Rates of the Red Sea Water during Jan 1958 - Dec 2007
Data set including sea level, temperature, salinity, and current from Simple Ocean Data Assimilation (SODA) is used in this study to estimate the mean net annually and seasonally evaporation rates. Then wind data is used to examine its impact on the evaporation. This work calculated the seasonal and annual evaporation rates based on assumption of that there is no net mass transport (balanced). Hence, the difference in the transport supposed to be equal to the water that has evaporated. Therefore data of water in-flow and out-flow used to examine the net mass transport with the obtained evaporation rate. Results revealed that the net annual mean evap- oration was 1.24 m/yr and the net seasonal mean was 1.3 m/yr and the evaporation rate in winter months was permanently higher than summer and autumn with min- imum value in August. The annual wind impact is masked but, it is clearer for the monthly, particularly in June and October. The monthly water exchange through Bab al-Mandeb Strait accompanied ...

Electrically and optically active polyaniline films doped with (1R)-(-)-10-camphorsulfonic acid were successfully deposited on nonconductive substrates via chemical vapor phase polymerization. The above polyaniline∕R-camphorsulfonate films were characterized by electrochemical and physical methods, such as cyclic voltammetry (CV), UV-vis spectroscopy, four-point probe conductivity measurement, Raman spectroscopy, circular dichroism spectroscopy, and scanning electron microscopy. The poly aniline films grown by this method not only showed high electrochemical activity, supported by CV and Raman spectrum, but also exhibited optical activity corresponding to the polymer chains as observed by circular dichroism spectra.

The important role of water in growth of monolayer transition metal dichalcogenidesThe important role of water in growth of monolayer transition metal dichalcogenides
Author(s): Kastl, C; Chen, CT; Kuykendall, T; Shevitski, B; Darlington, TP; Borys, NJ; Krayev, A; Schuck, PJ; Aloni, S; Schwartzberg, AM | Abstract: © 2017 IOP Publishing Ltd. 2D transition metal dichalcogenides (TMDs) are commonly grown by chemical vapor deposition using transition metal oxides as solid precursors. Despite the widespread use of this technique, challenges in reproducibility, coverage, and material quality are pervasive, suggestive of unknown and uncontrolled process parameters. In this communication, we demonstrate the impact of water vapor on this growth process. Our results show a direct correlation between gas phase water content and the morphology of TMD films. In particular, we show that the presence of water enhances volatilization, and therefore the vapor transport of tungsten and molybdenum oxide. Surprisingly, we find that water not only plays an important role in volatilization but is also compatible with TMD growth. In fact, carefully controlled humidity can consistently

The core experiments in this work were conducted in an experimental microcosm, or flux chamber. The chamber was constructed of 1 in anodized aluminum blocks, 30 cm long by 9 cm wide to which a sediment chamber measuring 10 cm long, 3 cm wide and 2 cm deep is attached. An air gap of about 0.2 cm is used to pass air of varying relative humidities. The contaminants that may vaporize into this moving air phase arecollected on an adsorbent trap in the effluent. Inoculated or field-contaminated sediment may be placed in the flux chamber and the potential for volatilization of contaminants measured. The observed vaporization rates were compared to models of the process. The experiments were able to reproduce a wide range of conditions that may apply in the field, from air-side to sediment-side mass transfer resistance controlled, to moisture content controlled volatilization. To illustrate, the air emissions of two polycyclic aromatic hydrocarbons (pyrene and phenanthrene) and one heterocyclic compound ...

Acute oral toxicity (acute toxic class method, method B1 of directive 2004/73/EC) and acute dermal toxicity (method B3 of directive 2004/73/EC) were determined in the rat. In both studies the test substance was administered neat at 2000 mg/kg bwt. Both studies were GLP-compliant, and the information is reliable and fully adequate for evaluation. There were no deaths, unusual clinical signs or necropsy findings in either study. The acute inhalation toxicity of a series on C9-C13 n-alkanes was investigated in male SD rats following a single 8-hr exposure to vapour. A calculated LC50 of 4467 ppm (equivalent to 23.4 mg/l) was determined for n-nonane. Given the extended duration of exposure used in these studies, the 4 -hr LC50 is likely to exceed this value. No mortality was recorded for C10 -C13 n-alkanes after exposure to the maximum achievable vapour concentration in air. The maximum saturated vapour concentration decreased in a predictable manner with increasing C-number. It is concluded, based ...

Our work explores the volatility of particles produced from two diesel low temperature combustion (LTC) modes proposed for high-efficiency compression ignition engines. It also explores mechanisms of particulate formation and growth upon dilution in the near-tailpipe environment. Moreover, the number distribution of exhaust particles from low- and mid-load dual-fuel reactivity controlled compression ignition (RCCI) and single-fuel premixed charge compression ignition (PPCI) modes were experimentally studied over a gradient of dilution temperature. Particle volatility of select particle diameters was investigated using volatility tandem differential mobility analysis (V-TDMA). Evaporation rates for exhaust particles were compared with V-TDMA results for candidate pure n-alkanes to identify species with similar volatility characteristics. The results show that LTC particles are mostly comprised of material with volatility similar to engine oil alkanes. V-TDMA results were used as inputs to an ...

Nicotinamide - Registration Dossier - ECHANicotinamide - Registration Dossier - ECHA
Manufacturing of Niacinamide and use may result in its release to the environment through various waste streams. Nicotinamide (vitamin B3) is a precursor of the coenzymes NAD and NADP. If released to air, an estimated vapor pressure of 0.00045 Pa at 25 °C indicates nicotinamide will exist in both the vapor and particulate phases in the atmosphere. Particulate-phase nicotinamide will be removed from the atmosphere by wet or dry deposition. If released to soil, nicotinamide is expected to have very high mobility based upon an estimated Koc of 15. Volatilization from moist soil surfaces is not expected to be an important fate process based upon an estimated Henrys Law constant of 2.9E-12 atm-cu m/mole. Nicotinamide was determined to be readily biodegradable in an aerobic screening test. If released into water, nicotinamide is not expected to adsorb to suspended solids and sediment based upon the estimated Koc.

Herein, an approach for simulating phase diagrams of binary mixtures is presented, where a bulk liquid and its corresponding vapour phase are simulated by means of molecular dynamics using explicit polarisation. Time-averaged density profiles for the pure compounds and mixtures at different mole fractions provide information about the spatial distribution in the bulk liquid and the amount of evaporated species in the adjacent vapour phase. The activities in the liquid phase are calculated from the mean vapour phase densities at a given composition, providing a good qualitative agreement compared to experimental data and the precision of the method follows a previously developed Poisson model of evaporation. With the Redlich-Kister approach for the activities in a binary mixture, the directly obtained activities are fitted providing corrected activity coefficients of the two species. This method is applied to ethanol water mixtures at different mole fractions. The obtained structural data are in good

Two experiments using calves fed 176 days from November to May (WINTER) and yearlings fed 117 days from May to September (SUMMER) were conducted to compare conventional CP levels to phase-fed diets balanced for degradable intake protein and undegradable intake protein on performance and N volatilization. Phase fed diets were formulated to balance degradable intake protein and metabolizable protein. Phase feeding resulted in greater ADG and better F:G in WINTER and similar performance in SUMMER than traditional feeding methods. Nitrogen excretion was significantly reduced in both WINTER and SUMMER which translated into significantly less N volatilization without impacting N removed in manure.

Sensitivity Analysis of CPPs for Solvent Removal Process of a API-Protein Bonded Nano-SuspensionSensitivity Analysis of CPPs for Solvent Removal Process of a API-Protein Bonded Nano-Suspension
Solvent extraction and evaporation is a widely used unit operation in the manufacturing of micro and nano-particles.. Due to the weak bond of the API to the protein, the product is highly sensitive to temperature, mechanical mixing and extraction/evaporation rate. A slow extraction/evaporation rate leads to changes of the particle size, which may result in blockage of the sterile filter and failure of the batch. In situations similar to this one, mathematical modeling is becoming a promising tool to improve the understanding and control of the CPPs and reduce the development time and cost.. The purpose of this work is to determine the sensitivity of different process parameters related to the solvent extraction/evaporation unit operation. A mathematical model was developed and applied to predict the duration required to accomplish the solvent extraction/evaporation process.. Turbulent Flow and Rotating Machinery physics interfaces in the CFD Module of COMSOL Multiphysics® were used to ...

Forecasting realized volatility: a Bayesian model-averaging approachForecasting realized volatility: a Bayesian model-averaging approach
Downloadable! How to measure and model volatility is an important issue in finance. Recent research uses high-frequency intraday data to construct ex post measures of daily volatility. This paper uses a Bayesian model-averaging approach to forecast realized volatility. Candidate models include autoregressive and heterogeneous autoregressive specifications based on the logarithm of realized volatility, realized power variation, realized bipower variation, a jump and an asymmetric term. Applied to equity and exchange rate volatility over several forecast horizons, Bayesian model averaging provides very competitive density forecasts and modest improvements in point forecasts compared to benchmark models. We discuss the reasons for this, including the importance of using realized power variation as a predictor. Bayesian model averaging provides further improvements to density forecasts when we move away from linear models and average over specifications that allow for GARCH effects in the innovations to

Abstract: This study presents new analytic approximations of the stochastic-alpha-beta-rho (SABR) model. Unlike existing studies that focus on the equivalent Black-Scholes (BS) volatility, we instead derive the equivalent volatility under the constant-elasticity-of-variance (CEV) model, which is the limit of the SABR model when the volatility of volatility approaches 0. Numerical examples demonstrate the accuracy of the CEV volatility approximation for a wide range of parameters.

Abstract: This study presents new analytic approximations of the stochastic-alpha-beta-rho (SABR) model. Unlike existing studies that focus on the equivalent Black-Scholes (BS) volatility, we instead derive the equivalent constant-elasticity-of-variance (CEV) volatility. Our approach effectively reduces the approximation error in a way similar to the control variate method because the CEV model is the zero vol-of-vol limit of the SABR model. Moreover, the CEV volatility approximation yields a finite value at a zero strike and thus conveniently leads to a small-time asymptotics for the mass at zero. The numerical results compare favorably with the BS volatility approximations in terms of the approximation accuracy, small-strike volatility asymptotics, and no-arbitrage region ...

Generalized dynamic factor models and volatilities: recovering the market volatility shocks - LSE Research OnlineGeneralized dynamic factor models and volatilities: recovering the market volatility shocks - LSE Research Online
Decomposing volatilities into a common market-driven component and an idiosyncratic itemspecific one is an important issue in financial econometrics. This, however, requires the statistical analysis of large panels of time series, hence faces the usual challenges associated with highdimensional data. Factor model methods in such a context are an ideal tool, but they do not readily apply to the analysis of volatilities. Focusing on the reconstruction of the unobserved market shocks and the way they are loaded by the various items (stocks) in the panel, we propose an entirely non-parametric and model-free two-step general dynamic factor approach to the problem, which avoids the usual curse of dimensionality. Applied to the S&P100 asset return dataset, the method provides evidence that a non-negligible proportion of the market-driven volatility of returns originates in the volatilities of the idiosyncratic components of returns.. ...

In this paper, Reversed-Flow Gas Chromatography (RF-GC) is utilized to investigate the evaporation of low molecular weight alcohol. Evaporation rates as well as the diffusion rates of methanol are determined with a surfactant monolayer on the surface of the liquid; while nitrogen acts as carrier gas, at 313 K. The precision (,99.9) and accuracy of this investigation demonstrates the potential of current methodologies for environmental impact studies; this is further verified when the results are compared with the available literature. The varying evaporation rates of methanol in the presence of varying amounts of Triton X-100 reflects that application of surfactants do damper the evaporation rates of liquid pollutants; without interference with the formers diffusion coefficients. High amounts of Triton X-100 are required for retardation of evaporation rates, suggesting the formation of a densely packed surface monolayer or the formation of an insoluble monolayer.. ...

Droplet lasing spectroscopy has been applied to the measurement of droplet size and evaporation rate in a spray. A single droplet, doped with laser dye, was injected along the centerline of a liquid spray. Filters were used to block the strong elastic-scattering signal. The lasing emission from the doped droplet could be detected against the background with mass loadings of liquid in the spray as high as 20%. An analysis of the spectrum of droplet lasing was used to evaluate the droplet diameter. The evaporation rate of the droplet was obtained from consecutive lasing spectra that were obtained from the same droplet. An error analysis of the drop size and drop evaporation measurements was carried out and showed that accurate measurements of evaporation rates were feasible.. © 1998 Optical Society of America.

The influence of the k-factor (0 and 1.5) of a single-hole axial-disposed injector (0.100 mm diameter and 10 L/d ratio) has been studied by spraying fuel in an optically-accessible constant-volume combustion vessel.A high-speed imaging system, capable of acquiring Mie-scattering and Schlieren images in a near simultaneous fashion mode along the same line of sight, has been developed at the Michigan Technological University using a high-speed camera and a pulsed-wave LED system. The time resolved pair of schlieren and Mie-scattering images identifies the instantaneous position of both the vapor and liquid phases of the fuel spray, respectively.

We reexamine this relationship in the context of globalization-a term typically used to describe the phenomenon of growing international trade and financial integration that has intensified since the mid-1980s. We employ various econometric techniques and a comprehensive new dataset to analyze the link between growth and volatility. Our findings suggest that, while the basic negative association between growth and volatility has been preserved during the 1990s, both trade and financial integration attenuate this negative relationship. Specifically, countries that are more open to trade appear to face a less severe tradeoff between growth and volatility. We find a similar, although slightly less robust, result for

Gases2
  • In TG-FTIR, gases evolved by volatilization or thermal decomposition are qualitatively analyzed, which allows you to track changes in the generated amount along with the temperature change. (rigaku.com)
  • however paramonochlorophenol was unable to exert antibacterial activity from the volatilization of its gases. (bvsalud.org)
Water3
  • Although the substance is found to be not readily biodegradable, the abiotic (volatilization and hydrolysis) processes are important and can indicate that the substance will not remain in water phase. (europa.eu)
  • Other sources of population exposure include drinking-water, tobacco smoke, and volatilization from building materials and consumer products. (who.int)
  • Chemicals (including disinfection byproducts) in drinking water or in recreational water that cause health effects either through water exposure or by volatilization leading to poor air quality are included. (cdc.gov)
