The effect of acute voluntary exercise session on pain threshold and tolerance in middle-aged tennis players

Aim: The purpose of this study is to examine the alterations in pain threshold and tolerance of middle-aged persons those who regularly play tennis at rest and following acute voluntary exercise. Methods: Fifty-nine recreationally-active persons aged 30-60 years participated in this study. Women and men separately were divided into 10-years groups, with 30-39, 40-49 and 50-59 years of age. Pressure pain threshold (PPT) and pain tolerance (PPT) measurements were recorded at rest and immediately following an acute exercise. PPT and PPTO values were measured from the biceps muscle of dominant arm by using a digital algometer. Singles tennis match was used as an acute voluntary exercise session, the duration of each tennis match (min) and rate of perceived exertion (RPE) were recorded. Results: No statistical differences were found in exercise duration or RPE scores among groups. RPE scores showed that tennis match played by participants was corresponded a strenuous exercise session. In all age groups, no statistical differences were found in baseline PPT or PPTO results in women or men. PPT and PPTO values were increased following exercise both in women and men. Although post-exercise PPT results were similar among age groups of women and men, PPTO values of men were found to be higher in all age groups of men in comparison with the same age groups of women. Conclusion: In conclusion, the present study revealed that one bout of voluntary exercise session resulted in gender-dependent differences in pain tolerance in middle-aged participants, and those middle-aged men were tolerated of pain at higher pressure levels following exercise in comparison with women at the same age.
ESA as a Significant Tool for Intensification of Structural Elements of Pipe Systems

Complex mechanical systems intended for gas transport are formed by complicated technological piping units. Their main components are gas pipelines, compressor stations, connection and distribution nodes, etc. As a part of their operation, monitoring but especially within long-term intensification of their technical competence, it is necessary to solve a variety of complex technical problems. These are mainly related to monitoring and prediction of lifespan of critical system elements, then also to monitoring corrosion damaged pipeline and related repairs and eventually to rectification of older bridges and other temporary or unsatisfactory technical solutions. Important interacting negative factors in the process are gradual degradation of used material, presence of residual stresses, etc. Solving these problems is unthinkable without active application of experimental modeling, relevant experimental methods and corresponding hardware and software. This mainly includes means of modal analysis and analysis of deformation and mechanical stresses. The article also presents relevant conclusions from solving environment of specific technical problems in the conditions of gas piping transport system in the Slovak Republic.
Empirical Comparison of the In Situ Methods for Determining Sound Power of Typical Embroidery Machine Located in Industrial Workroom

Sound power is considered as an excellent measure for evaluating the efficiency of noise controls as well as for comparing noise sources in workrooms. This parameter can be determined by sound pressure or intensity based methods in real conditions of workrooms. This paper aims empirically to compare these in situ methods in relation to a typical industrial machine located in workroom in terms of accuracy, applicability. Determination of sound power of a typical model of noisy embroidery machine located in enclosed workroom was performed in the interested frequency range of 125 Hz to 4000 Hz. Field measurement of sound power was conducted using the BSWA sound analyzer according to ISO 9614 and ISO 3746, respectively. The results showed SWL spectrum of the source was relatively high with flat noise spectrum. Operation speed was one of the most important features which could influence the noise of embroidery machine. In regard to uncertainty values, the sound power spectra, obtained using the two methods, showed acceptable agreement from the viewpoint of applicability. The higher value for pressure methods can be due to fluctuations in background noise and method limitations. Direct measurement of reverberation time compared with approximate method could improve the accuracy of the pressure method. Hence, pressure method can be employed by occupational health experts as an alternative to intensity method. Due to its direct and more accurate measurements, intensity method is considered to be a more preferred technique in order to describe any noise sources and to evaluate noise controls at sources.
Analytical Decision Supports System for Urban Air Quality Management in Tehran: Meteorological and Photochemical models

A new analytical air pollution modeling system is introduced in this paper to estimate concentrations of primary and secondary air pollutants and using it for further studies in order to improve the knowledge of pollutants emission and dispersion over Tehran, and developing a decision support system. For this purpose, WRF/CAMx modeling system was used to simulate the gas-phase pollutants concentrations including primary and secondary pollutants, over Tehran during a wintertime episode, which is characterized by very high concentrations of pollutants. Pollutants were triggered by meteorological conditions leading to a forced holiday imposed on citywide operations to protect the health of citizens. Based on calculated Values of NMB error, WRF performs acceptable in predicting temperature and wind speed. Generally, time series plots show that WRF performs acceptable in mild selected episode. Also, the daily trends of pollutant concentrations are greatly affected by changes in local meteorological conditions such as planetary boundary layer (PBL) height, temperature, wind, and relative humidity over the Tehran area. An underestimation in prediction of all pollutants concentrations episode at Poonak and Aghdasyeh sites show due to the insufficient emission data at the site position used for the simulation were seen. Results showed that WRF/CAMx modeling system proved to be a useful tool for analyzing urban environmental problems, investigating the impact of air quality control policies, and predicting critical conditions. However, there were weaknesses in input data and modeling system calibration that should be improved before using the system for further studies.
Metabolomic and Proteomic Analysis of Moringa oleifera L . Cultivated with Vermicompost and Phosphate Rock under Water Stress Conditions

Interest in the plant gender Moringa oleifera has grown in recent years as it is a plant that can potentially provide a good amount of nutrients necessary for human consumption. Thus, humans could benefit from nutrient enrichment in this plant and produce foods with high protein content. Protein and metabolite content is influenced by soil type, organic input and frequency of irrigation. For this reason we evaluated the effect of different culture conditions on the metabolomic profile and protein concentration leaf of M. oleifera. The cultivation of Moringa oleifera with organic inputs was conducted in a greenhouse. Nutrient sources were vermicompost nitrogen at a fertilization rate of 150 kg/ha, phosphate rock as a source of phosphorus at a rate of fertilization of 96 kg P/ha and urea (control) at a rate of 150 kg N/ha. The experimental design was a split plot with randomized complete block. The frequency of irrigation was monitored for each of the levels of water holding capacity (WHC), low (25% WHC), medium (40% WHC) and high (55% WHC). The application of soil-rock phosphate-vermicompost increases morphometric parameters significantly at 45 and 90 days. UPLC-ESI-MS/MS analysis of leaf extracts revealed that the most abundant metabolites were flavonoids, alkaloids and terpenes. Thus, water stress induced changes in the metabolomic profile and the morphometric variables of Moringa oleifera. These results are important for Moringa industrialization for metabolite production culture in different crop conditions. © 2019 Friends Science Publishers
Mnemic neglect and self-threat: Trait modifiability moderates self-protection

The mnemic neglect effect is the phenomenon of disproportionately poor recall for threatening (rather than non-threatening) feedback that refers to the self (rather than another person). Does trait modifiability moderate mnemic neglect? We hypothesized that mnemic neglect will be present for feedback on unmodifiable traits, but absent for feedback on modifiable traits. In the latter case, the feedback would be lower in threat potential because its consequences are fleeting and steps to prevent its reoccurrence are possible. Participants received mixed (threatening and non-threatening) feedback that referred either to the self or another person. The feedback pertained to (central and peripheral) self-conceptions that were either unmodifiable or modifiable. In support of the hypothesis, mnemic neglect emerged for feedback on unmodifiable, but not modifiable, traits. The findings illustrate the selective and strategic nature of self-protection.
Emissions of NO, NO 2 , and PM from inland water transportation

Particulate matter (PM) and nitrogen oxides NOx (NOx = NO2 + NO) are key species for urban air quality in Europe and are emitted by mobile sources. According to European recommendations, a significant fraction of road freight should be shifted to waterborne transport in the future. In order to better consider this changed emission pattern in future emission inventories, in the present study, inland water transport emissions of NOx, CO2 and PM were investigated under 10 real world conditions at the river Rhine, Germany in 2013. An average NO2/NOx emission ratio of 0.08 ± 0.02 was obtained, which is indicative of ship diesel engines without after-treatment systems. For all measured motor ship types and operation conditions overall weighted average emission indices of EINOx = 54  4 g kg -1 and a lower limit EIPM1 =  2.0  0.3 g kg -1 were obtained. EIs for NOx and PM1 were found to be in the range of 20–161 g kg -1 and  0.2–8.1 g kg -1 , respectively. A comparison with threshold values of national German guidelines shows that the NOx emissions of all investigated motor ship 15 types are above the threshold values, while the obtained lower limit PM1 emissions just within. To reduce NOx emissions to acceptable values, implementation of after-treatment systems is recommended.
GHGT-12 Heat of absorption of carbon dioxide ( CO 2 ) into aqueous N-methyldiethanolamine ( MDEA ) and N , N-dimethylmonoethanolamine ( DMMEA )

In this work the heat of absorption of CO2 into aqueous solutions of N-methyldiethanolamine (MDEA) and N,Ndimethylmonoethanolamine (DMMEA) has been investigated in a reaction calorimeter. The experiments were conducted at the concentrations 2M and 4.2M, and the temperatures 313 K, 353 K and 393 K. The resulting differential heats of absorption were plotted as a function of liquid CO2 loading. An effect of temperature on the heat of absorption was observed for MDEA. This effect was larger at low loadings and the lower amine concentration. This was also observed for DMMEA but here the effect of temperature was larger. The heat of absorption of CO2 into aqueous DMMEA is slightly larger than for MDEA. © 2013 The Authors. Published by Elsevier Ltd. Selection and peer-review under responsibility of GHGT.

The survival of velvet mesquite (Prosopis juliflora var. velutina) after fire

Fire can affect plant distribution through the differential effect it has on the various species and lifeforms found in a plant community. On this basis many ecologists have concluded that natural wildfires were formerly a major factor in controlling brush species and preventing their spread over the grasslands they have invaded in so many places in recent times. Various opinions exist, however, on the importance of fire as a factor in the control of the original range of mesquite within the desert grassland. In recent times, broadcast burning has been developed as a valuable tool in controlling many noxious plants on the range. But again little is definitely known concerning the effect of fire on mesquite or the possible value of fire as a tool in clearing mesquite-infested grasslands. The role of fire in restricting mesquite to its original range along the drainages in much of the desert grassland has been discussed by many authors. As early as the beginning of the last century Michaux (1805), based on his experience from travels in the Midwest, mentions the possibility of wildfires as the cause of the treeless prairies of New Mexico. At the beginning of this century several investigators in the southwestern United States concluded that fires were a factor in keeping mesquite
Crowdsourcing for rangeland conditions—Process innovation and beyond

Rangeland forage conditions are so closely associated with the wellbeing of pastoralists that they are frequently used by humanitarian agencies to monitor for coming disasters (Luseno et al. 2003; Aboud et al. 2006). Information on forage conditions is also necessary for rangeland management programs, and is used by development and government programs working to mitigate the risks that pastoral households face (Kurtz et al. 2010; Kadi et al. 2011, Fernández‐Gimenez et al. 2012; Chantarat et al. 2013).
Observation and modeling of stable water isotopes as diagnostics of rainfall dynamics over southeastern Australia

[1] A unified approach of observation and modeling was applied to the investigation of three circulation types that typically bring rain to southeastern Australia. Observations from the Melbourne University Network of Isotopes in Precipitation of high-resolution variations in the ratios of 18O and 2H were collected for (1) mixed frontal, (2) convective, and (3) stratiform precipitation events. Isotopic content of precipitation varied over both high and low frequencies because of influences from local variations in rain intensity and rainout by large-scale precipitation. Deuterium excess showed a weak relationship with rainfall amount on intraevent time scales but was stronger under convective rainfall conditions. As a supplement to the observations, a version of the National Center for Atmospheric Research Community Atmosphere Model running an isotope hydrology scheme simulated the mixed frontal and stratiform events by nudging with reanalyses. The simulations represented well the evolution of vapor profiles of 18O and deuterium excess. Trajectories for the mixed frontal case illustrated the structure of the vapor profiles, revealing a convergence of air masses from different source regions. Deuterium excess in precipitation was represented less accurately by the model, indicating a possible shortcoming in the parameterization of postcondensation processes in the general circulation model. By combining observations and modeling in this way, detail of the structure and history of the events was provided that would be unavailable from the sampling of precipitation alone.
ADDIS ABABA UNIVERSITY SCHOOL OF GRADUATE STUDIES TRADE LIBERALIZATION , INEQUALITY AND POVERTY IN ETHIOPIA : A DYNAMIC COMPUTABLE GENERAL EQUILIBRIUM MICROSIMULATION ANALYSIS

This study examines the short run and long run impacts of unilateral trade liberalization, in terms of a complete and instantaneous import tariff removal, on sectors of the Ethiopian economy and household poverty and inequality. The study utilized a dynamic sequential CGE model, employing a ‘top-down’ approach to carry out the microsimulation analysis of poverty and inequality. We used WB SAM of 1999/2000 and CSA household survey of 1999/2000 that comprises of 17332 households. The main findings of the analysis are complete and instantaneous tariff removal in the Ethiopian economy would lead to a worsening of poverty in the short run, and contraction of the initially protected industry, particularly industry and services. In the long run, trade liberalization combined with capital accumulation reduces poverty and swells sectors that were contracted in the short run. The growth effect captured by the model contributes to the expansion of all sectors, particularly agriculture and reduces poverty. The decomposition of changes in poverty indicates growth is pro-poor.
Verification and analysis of a climate simulation of temperature and pressure fields over Norway and Svalbard

The monthly mean 2 m temperature and sea-level pressure (SLP) fields from the most recent integration (GSDIO) with the Max Planck Institute's global coupled climate model ECHAM4/OPYC3 are compared to historical data over Norway including Svalbard. For temperature, observations from selected stations are directly compared to values at grid points nearby. For SLP, modelled and observed gridded fields over the area 20° W-40° E, 50-85° N are compared by means of empirical orthogonal function (EOF) analysis. Finally, the connections between SLP and tempera- ture over Norway are deduced for both historical data and results from the GSDIO integration and then compared to each other. The GSDIO 'control climate' grid point temperatures over Norway are in most cases found to be realistic, whenever it is possible to find stations with similar altitude and dis- tance from the coast. The GSDIO 'future climate' indicates an annual mean warming of 0.2 to 0.5°C decade -1 on the Norwegian mainland, and 0.8°C decade -1 at the Svalbard grid point up to 2050. The strongest warming is simulated in winter, in the inland, and at high latitudes. The GSDIO 'control cli- mate' SLP gradients imply on average westerly winds over Norway that are too weak. The GSDIO 'future climate', however, indicates an increase in the westerly wind component. Observations after 1960 show an increase in the westerly field of the same magnitude as in the GSDIO results during the same period. The observed connections between atmospheric circulation and temperatures in Nor- way are satisfactorily reproduced in the GSDIO integration, especially in winter. The winter warm- ing in the GSDIO integration may partly be explained by the increase in the westerly wind compo- nent. On the Norwegian mainland, a linear regression model based on atmospheric circulation indices accounts for 1 ⁄3 to 2 ⁄3 of the 'scenario' warming in January. In July, the linear regression model does not account for any warming at all. The warming which is not accounted for by the linear regres- sion model may be caused by non-linear processes (e.g. air-sea-ice interactions) or directly connected to changes in the climate forcing.
A novel and widely accessible HPLC method for determination content of homosalate in sunscreen products on the market

Introduction: Considering that the research has shown that homosalate act as endocrine-active substance, it is very important to develop quick and sensitive method for tracking its concentrations in sunscreen products. The aim of this paper is to develop and validate the method for determining homosalate in sunscreen preparations and controlling the content of the products found on the market of Bosnia and Herzegovina. Methods: A high pressure liquid chromatography (HPLC) method for determination homosalate in sunscreen products has been developed and validated. Samples of six different manufacturers have been analyzed. HPLC method is method of choice for this type of investigation. Results: According to the calibration curve it has been found that the proposed analytical method in a given range of concentration is linear and that the correlation coefficient is R2=0.9998. Accuracy of the method is in range 94.26% -121.53%. The results have shown that the homosalate concentration in the tested samples did not exceed the maximally permissible concentration (10%). In the sample AV50 homosalate was not declared as an active ingredient, but it was identified and quantified at a concentration of 0.143%. Conclusion: Results of investigation of cosmetic products that are widely present on the market show the need of developing a sufficiently sensitive, easily accessible, analytical method for controlling the content of organic UV filters since the exceeding of the maximally permissible concentration can have a harmful effect on people who use these kinds of products. The results show that developed method meets conditions and is suitable for wide application.
