Effect of Relative Humidity on the Growth, Transpiration Rate and Respiration Rate of Cucumber Fruit
The respiration rate of green capsicum cv. ‘Swarna’ fruits harvested at mature green stage were determined under closed system at 10, 15 and 20 oC temperatures. A simple Michaelis-Menten kinetic model coupled with Arrhenius-type equation, which describes temperature as a function of respiration rate, was used to model the respiration rate of capsicum. The respiration rate model parameters at de...
Recent human isolated muscle fiber studies suggest that phosphocreatine (PCr) and creatine (Cr) concentrations play a role in the regulation of mitochondrial respiration rate. To determine whether similar regulatory mechanisms are present in vivo, this study examined the relationship between skeletal muscle mitochondrial respiration rate and end-exercise PCr, Cr, PCr-to-Cr ratio (PCr/Cr), ADP, ...
در این تحقیق، مدل دینامیکی جذب ذرات در ریه (شش ها) بر اساس دیدگاه اویلری-اویلری تدوین شده است. شبیه سازی مدل در طول کل ریه انجام شده و مقدار جذب در هر نسل از ریه بوسیله حل عددی معادله gde بدست آمده است. همه مکانیزم های مختلف جذب ذرات منظور شده و تأثیر هر مکانیزم با توجه به اندازه ذرات تحلیل شده است. معادله gde به صورت یک بعدی و با استفاده از روش مقاطع برای بدست آوردن توزیع ذرات تنفس شده در طول ...
Temperature is an important factor regulating microbial activity and shaping the soil microbial community. Little is known, however, on how temperature affects the most important groups of the soil microorganisms, the bacteria and the fungi, in situ. We have therefore measured the instantaneous total activity (respiration rate), bacterial activity (growth rate as thymidine incorporation rate) a...
A L T H O U G H there is considerable evidence that carbohydrate metabolism plays an important part in the process of cell division (see Bullough, 1952), conclusions have differed regarding the relative importance of glycolysis and catabolism involving respiration. In the adult mouse epidermis Bullough & Johnson (1951) found that cell division was dependent upon the respiratory oxidation of pyr...
The kinetics of regulation of mitochondrial respiration by endogenous and exogenous ADP in muscle cells in situ was studied in skinned cardiac and skeletal muscle fibres. Endogenous ADP production was initiated by addition of MgATP; under these conditions the respiration rate and ADP concentration in the medium were dependent on the calcium concentration, and 70-80% of maximal rate of respirati...
Information on the respiration rate and the low O2 limit (LOL) is important for optimization of packaging and storage systems for fresh fruit and vegetables. In this study, a small and flexible sensor-based respirometer was developed for real-time determination of the respiration rate, respiratory quotient (RQ), and LOL of fresh produce. The respirometer consisted of a wide mouth 1-L glass jar ...
