Several controversies currently dominate the fields of arthropod metabolic rate, gas exchange and water balance, including the extent to which modulation of gas exchange reduces water loss, the origins of discontinuous gas exchange, the relationship between metabolic rate and life-history strategies, and the causes of Palaeozoic gigantism. In all of these areas, repeated calls have been made fo...

abstract the aim of this study, is to evaluate the effect of loss methods application on run-off volume and hydrograph shape used by hydrologic models. in this research, four loss methods including constant loss (φ index), initial loss-loss rate, scs and constant fraction approach were applied to be evaluated. to do this, clark rainfall-runoff model was applied for 24 storm events from kasilain...

the aim of this study was to compare the effect of one swimming session in different water temperatures (23, 33 and 38̊ c) on the appetite, calorie intake, calorie consumption, food liking, and the amount of blood lactate in female students. the research design was semi-experimental and 12 female volunteers (mean age 20.83 ± 1.3 yr, bmi 20.46 ± 2.68 kg/m², weight 53.6 ± 5.46 kg) from university ...

Measurements of heat collection rate and heat loss coefficient are crucial for the evaluation of in service water-in-glass evacuated tube solar water heaters. However, conventional measurement requires expensive detection devices and undergoes a series of complicated procedures. To simplify the measurement and reduce the cost, software based on artificial neural networks for measuring heat coll...

Global nitrogen (N) deposition and climate change have been identified as two of the most important causes of current plant diversity loss. However, temporal patterns of species turnover underlying diversity changes in response to changing precipitation regimes and atmospheric N deposition have received inadequate attention. We carried out a manipulation experiment in a steppe and an old-field ...

The hygric hypothesis postulates that insect discontinuous gas exchange cycles (DGCs) are an adaptation that reduces respiratory water loss (RWL), but evidence is lacking for reduction of water loss by insects expressing DGCs under normal ecological conditions. Larvae of Erynnis propertius (Lepidoptera: Hesperiidae) naturally switch between DGCs and continuous gas exchange (CGE), allowing flow-...
