The improvement of probabilistic assessments extreme air temperature events is a major goal for agrometeorological studies. regional frequency analysis based on L-moments (RFA-Lmom) has been successfully used to improve the study hydrometeorological variables such as rainfall events. This investigated hypothesis that RFA-Lmom can be applied maximum (Tmax) and minimum (Tmin) data. RFA-Lmon was c...
126 abstract: in this research we studied the effects of cyclic hydration and dehydration of cysts of artemia urmiana and artemia parthenogenetica on the hatching percentage, survival and growth. the experiment was carried out in 3 treatments (1-3 hydration/dehydration cycles) with 3 replicates for each treatment. later effects of cold preservation at -20°c during three time periods were ...
Apple cultivars in Korea have been experiencing poor fruit sets due to early spring low temperatures and global warming. Therefore, the present study aimed investigate effects of temperature on setting select apple tolerant extreme based response their pollen. The effect pollen germination percentage (PGP) tube length (PTL) was determined under laboratory conditions using ten cultivars. two par...
This study evaluates the skills of 30 CMIP5 GCMs and Multimodel Ensemble (MME) in reproducing characteristics observed precipitation (Pr), minimum (Tmin), maximum (Tmax) temperature over Middle Awash sub-basin (MASB) Ethiopia. The MME climate variables was generated using simple arithmetic mean method. entire analysis performed on raw historical GCM simulations (before bias correction) data for...
Abstract The diurnal temperature range (DTR) as measured by the difference between daily maximum (Tmax) and minimum (Tmin) temperatures is of great importance to human health, ecology, agriculture. link its long-term change anthropogenic forcing still unclear. This study shows evidence influence on changes in DTR over globe, five continents, China during past century (1901–2014). Using multiple...
With global warming, recent winters in Switzerland have been milder than previous decades, and this trend is predicted to continue. Survival during the cold season could increase for insect species sensitive winter events. Forest pests, such as pine processionary moth (Thaumetopoea pityocampa) green spruce aphid (Elatobium abietinum), well some crop southern stink bug (Nezara viridula), overwin...
We present a heuristic, semiphenomenological model of the anomalous temperature (T) dependence of resistivity ρxx recently observed experimentally in the quasi-one-dimensional (Q1D) organic conductors of the (TMTSF)2X family in moderately strong magnetic fields. We suggest that a Q1D conductor behaves like an insulator (dρxx/dT < 0), when its effective dimensionality is one, and like a metal (d...
Based on monthly precipitation (P), temperature (T) data, and remote sensing images collected from March 2000 to February 2019, this article was constructed reveal the synergistic effect between P T for NDVI in northern China qualitatively quantitatively by using a one-variable linear regression, coefficient of variation, multivariate correlation coefficients, geodetector. The results show that...
