Abstract:
This experiment was conducted on the 4 years old Eucalyptus plantation in Beihai of Guangxi, southern China. From January to December 2013, in the spring, summer, autumn and winter, seasonal variation and diurnal variation of the soil respiration and its environmental factors had been observed, respectively. The results showed that: (1) Soil respirations has obvious seasonal characteristics, the soil respiration rate in each seasons showed that: summer> spring > autumn > winter. The heterotrophic respiration rate was higher than the autotrophic respiration rate. The contribution of autotrophic respiration rate in winter was higher than that in other three seasons. (2) Soil respiration has obvious diurnal characteristic, it could be expressed as a single-peak curve. But the maximum value of soil respiration appeared in different times in different seasons. (3) There existed positive correlation index exponential relationships between the soil temperature and the soil respiration rate and its components. Soil temperature changes could explain soil respiration, autotrophic respiration and heterotrophic respiration by 90.2%, 27.5% and 92.8%. Temperature sensitivity showed following order: the heterotrophic respiration rate> the soil respiration rate> the autotrophic respiration rate, in terms of affected by temperature, the heterotrophic respiration was higher than the autotrophic respiration. (4) There were notable positive correlations between soil moisture content and soil respiration rate. Obviously, soil moisture content could promote soil respiration in a certain range.

Abstract:
The influence of a 24-week program including running exercises and endogenous hypoxic respiration method on the parameters of external respiration was studied. After 8 and 16 weeks a spectrum of volume and speed parameters of external respiration improved. The changes in the above mentioned parameters are an indication of the better spare capacity of external respiration system and better functional capacity of respirational muscles. Positive changes in speed spirometry parameters characterize improved air passage through different sections of bronchi.

Abstract:
Breathing or respiration has been essential in human life since ancient times. Philosophers and physicians of ancient times such as Hippocrates, Galen, and others had already written about breathing in literature. These antiquated viewpoints established the foundation for contemporary respiratory physiology and medicine. The Hippocratic literature established the importance of breath in maintaining the body's humour balance, whereas Galen elaborates on the anatomical and functional elements of respiration. Literature related to respiration is surveyed from various Unani classical books and their translations, commentaries, previous dissertations, journals, proceedings, etc. Hippocrates and Ibne Sina mentioned ten and seventeen types of respiration respectively. Ibne Sina also explained five special types of respirations. This research paper aims to explore and analyse the understanding and significance of respiration in the Unani system of medicine. And also provides a comprehensive overview of how ancient philosophers understood respiration.

Abstract:
Both soil temperature and soil water condition are important factors that influence soil respiration at different forest. In this study, a throughfall exclusion experiment was carried out to explore effects of increased soil temperature and decreased soil water content on soil respirations in the bamboo forest in North Zhejiang of China. The results showed that 1) monthly variation in soil respiration ranges from 2.00 to 0.63μmol·m-2·s-1 and 2.20 to 0.66μmolm-2s-1in throughfall exclusion and control plots respectively. The soil respiration monthly variation following the monthly variation of soil temperature and in contrast to the monthly soil water content. 2) Soil temperature can explain 65.5%and 73.9% of the variance of soil respiration in throughfall exclusion and control plots respectively. Multivariate linear model based on temperature and soil water content explained 66.9% and 73.4% of the variance of soil respiration in throughfall exclusion and control plots respectively. Soil water content had no significant relationship with soil respiration. Q10 values of throughfall exclusion and control plots were 5.99 and 4.44.

Abstract:
In this study were compared heterotrophic respiratory potential (VDS/VMAX) expressing an increase in C mineralisation rate after drying and re-wetting the soil to 60% soil water content (v/w)(VDS) in relation to maximum respiration rate (VMAX) after glucose addition, and VMAX in organomineral soil (Ah horizon) of mod­erately mown and for 11 years abandoned mountain meadows in Moravian-Silesian Beskids Mts. VDS/VMAX and VMAX were assessed in soil samples taken in 30-day intervals throughout the period of May–September 2004. The results obtained showed higher VDS/VMAX on the abandoned meadow throughout the whole experiment except the last sampling occasion, and higher VMAX throughout the whole experiment. Significantly (P < 0.05) higher VDS/VMAX on the abandoned meadow was found in May and July, VMAX was significantly higher on the same meadow (P < 0.05) only in September. From the parameters studied, the time of sampling had no significant (P > 0.05) effect on VMAX when the data from the moderately mown meadow were evaluated. On the abandoned meadow, VMAX found was significantly (P < 0.05) different when the samples from May and September or July and September were compared. A significant (P < 0.05) effect of the sampling time on VDS/VMAX on the moderately mown meadow was presented by differences between May and other sampling times, on the abandoned meadow differences between September and other times of sampling except May were significant (P < 0.05).

Abstract:
The effects of two herbicides on soil respiration, the activity of catalase and the activity of urease were studied in laboratory. The results showed that effects of atrazine and nicosulfuron on soil respiration were different. The soil respirations were in inhibition when soils were treated with atrazine, while soil respirations were in promotion-inhibition-recover when soils were treated with nicosulfuron. The soil respirations were different at different herbicide concentrations. According to coefficient of injury, herbicides atrazine and nicosulfuron both belong to low toxicity herbicides or no toxic herbicides. The effects of herbicides on the activities of catalase and urease were same, which were inhibition-recovery. The activity of unease was inhibited by atrazine and nicosulfuron before 21d. Half dosage of nicosulfuron has a significant inhibitory effect. The different concentrations of atrazine and nicosulfuron had no obvious effect on the catalase activity.

Abstract:
Ce qui est en jeu, c' est l' expérience temporelle de l' oeuvre dans laquelle la conscience du spectateur engage sa propre temporalité au moment même ou il en fait l' expérience vécue à la fois physiquement et métaphysiquement. Cette réalité expérimentale dans une certaine durée et un certain espace, comme un événement de la vie est un élément spécifique de notre travail «Sculpture-Installation ». Dans cette idée de l' oeuvre, des spectateurs sont invités dans un espace plein de vitalité et d'imagination. Par conséquent l' espace de l' oeuvre se transforme en un dispositif où les rapports entre l' artiste et Ie spectateur sont plus dynamiques que statiques. Ce type de création concernant l' espace est un effort pour créer une autre réalité, qui soit la métaphore d'une réalité profonde de notre vie, un espace comme lieu d' expérience, comme un dispositif de vie. Cette extension des limites du lieu et de l' espace nous amènera à ces interrogations: l' oeuvre est-elle pour le spectateur un objet qui anime le lieu, ou est -ce l' espace qui est modifié par la présence d' un objet artistique ? Le but de notre thèse est de se livrer à une recherche sur la production artistique concernant la problématique de l' espace et de l' oeuvre, et l' expérience temporelle du spectateur. La question de l' « habitation» de l' oeuvre consiste à proposer en un lieu des itinéraires multiples, le long desquels alternent objets naturels et objets issus des nouvelles technologies.

Full text
Abstract:

Several bacterial species are capable to use perchlorate and/or chlorate as an alternative electron acceptor in absence of oxygen. Microbial respiration of oxochlorates is important for biotreatment of effluent from industries where oxochlorates are produced or handled. One of these species, the Gram-negative Ideonella dechloratans, is able to reduce chlorate but not perchlorate. Two soluble enzymes, chlorate reductase and chlorite dismutase, participate in the conversion of chlorate into chloride and molecular oxygen. The present study deals with the electron transport from the membrane-bound components to the periplasmic chlorate reductase. Soluble c cytochromes were investigated for their ability to serve as electron donors to chlorate reductase. The results show that a 6 kDa c cytochrome serves as electron donor for chlorate reductase. This cytochrome also serves as electron donor for a terminal oxidase in the reduction of oxygen that is produced in the course of chlorate respiration. A gene encoding a soluble c cytochrome was found in close proximity to the gene cluster for chlorate reduction. This gene was cloned and expressed heterologously, and the resulting protein was investigated as a candidate electron donor for chlorate reductase. Electron transfer from this protein could not be demonstrated, suggesting that the gene product does not serve as immediate electron donor for chlorate reductase.

Abstract:
Abstract Patients with SMID (severe motor and intellectual disabilities) have severe limb disorders and severe mental disabilities. More than half of their deaths are due to respiratory disorders. Therefore, respiratory rehabilitation is important. The effect of respiratory rehabilitation is generally determined by measuring respiratory volume and rate with an expired gas analyzer. However, the equipment is expensive and requires direct contact, making it difficult to use. The purpose of this research is to develop a non-contact measurement system for respiratory function to assess the effect of respiratory rehabilitation in patients with SMID. The proposed method detects respiration by depth change of the abdomen measured using a three-dimensional camera designed to identify body tremor /motion and respiration based on respiratory parameters and individually adapted parameters. Finally, we verify the rehabilitation effect of an RTX respirator on patients with SMID and the effectiveness of the proposed method in an experiment.

Full text
Abstract:
Forest ecosystems of different tree species participate actively in climatic and biotic processes, such as photosynthesis, plant and soil respiration, therefore knowledge of soil respiration, especially of CO2 emissions to the atmosphere is of great importance. The aim of the study was to determine soil respiration rate of stands of deciduous (Betula pubescens Ehrh., Quercus robur L.) and coniferous (Larix eurolepis Henry, Thuja occidentalis L.) tree species as well as impact of abiotic (soil temperature, humidity, electrical conductivity, pH) and biotic (abundance of undergrowth, shrub, herbs) factors. Measurements of CO2 emissions, temperature, moisture and electrical conductivity were performed in-situ in the stands of different tree species with portable ADC BioScientific LCpro+ system and digital electrochemical device “Wet” (Delta-T). Soil samples were collected for the physicochemical analysis simultaneously. Chemical analysis of soil samples was done at the lab of the Environmental Research of the Aleksandras Stulginskis University by standard methods. Soil respiration was highest in the stand of Thuja occidentalis and lowest in the stand of Betula pubescens. Soil respiration intensity of the tree stands increased as follow: Thuja˂ Quercus˂ Larix˂ Betula. In the coniferous tree stands, the soil respiration was lower on average 27% comparing to deciduous tree stands. Soil respiration rate increased with increase of herbaceous vegetation cover and temperature. Soil respiration rate was mostly influenced by abundance of herbaceous vegetation (r = 0.91) of all biotic factors investigated, while soil temperature (r = 0.75) of abiotic factors. 60 years old stands of different tree species formed specific conditions what influenced different soil respiration rates.

Abstract:
Subarctic and Arctic environments are sensitive to warming temperatures due to climate change. As soils warm, soil microorganisms break down carbon and release greenhouse gases such as methane (CH₄) and carbon dioxide (CO₂). Recent studies examining CO₂ efflux note heterogeneity of microbial activity across the landscape. To better understand carbon dynamics, our team developed a predictive model, Dynamic Representation of Terrestrial Soil Predictions of Organisms’ Response to the Environment (DRTSPORE), to estimate CO₂ efflux based on soil temperature and moisture estimates. The goal of this work was to acquire respiration rates from a boreal forest located near the town of Fairbanks, Alaska, and to provide in situ measurements for the future validation effort of the DRTSPORE model estimates of CO₂ efflux in cold climates. Results show that soil temperature and seasonal soil thaw depth had the greatest impact on soil respiration. However, the instrumentation deployed significantly altered the soil temperature, moisture, and seasonal thaw depth at the survey site and very likely the soil respiration rates. These findings are important to better understand the challenges and limitations associated with the in situ data collection used for carbon efflux modeling and for estimating soil microbial activity in cold environments.
