Based on the daily minimum air temperature (Tmin) data from China Meteorological Data Network and NCEP/DOE reanalysis data, intra-seasonal circulation characteristics evolution of extreme cold events (ECEs) in Northeast–North (NE-N) during winter 1979–2018 are explored, synergistic effects key systems mid-high latitude ECEs discussed. The results show that: (1) Tmin NE-N region presents a signi...

The response of the citrus crop to environmental supply largely determines speed and intensity plant's ecophysiological processes, which affect development production crop. main objective was analyze effects climatic conditions on productivity ‘Valencia’ orange agroecosystems (Citrus sinensis L. Osbeck) previously typified in department Meta, Colombia. climatological variables precipitation (PP...

Two dimensional correlation spectroscopy is a powerfull tool for spectral analysis. It is able to reveal correlations between spectral changes and to deconvolve overlapping peaks. It is easily applicable in a study of biomolecules. Here presented program was created for easy accessibility of all necessary operations. Presented algorithm was deeply tested on regular spectra as well as on a spect...

The ability of a natural enemy to tolerate a wide temperature range is a critical factor in the evaluation of its suitability as a biological control agent. In the current study, temperature-dependent development of the two-spotted ladybeetle A. bipunctata L. (Coleoptera: Coccinellidae) was evaluated on Myzus persicae (Sulzer) (Hemiptera: Aphididae) and a factitious food consisting of moist bee...

BACKGROUND To analyze protective/regenerative effects of adipose tissue-derived mesenchymal stem cells (ADMSC) on 131I-Radioiodine (RAI)-induced salivary gland damage in rats. MATERIALS AND METHODS Study population consisted of controls (n:6) and study groups (n:54): RAI (Group 1), ADMSC (Group 2), amifostine (Group 3), RAI+amifostine (Group 4), concomitant RAI+ADMSC (Group 5) and RAI+ADMSC a...

Abstract Cover crops planted in the offseason are subjected to uncontrollable weather variables that limit agro‐ecological services through modifications growth and development. The of five cover crop species was investigated response an array day/night temperatures, 17/9, 22/14, 27/19, 32/24, 37/29 °C. Shoot root parameters were measured 33 d after planting. Quadratic functions best described ...

Global warming has become a major threat to life on the earth, and recognizing its impacts can definitely be useful in controlling mitigating adverse effects. In this study, time series variations air temperature indices (frost days, Tmin, Tmax, Tmean, Tminmin, Tmaxmax, Tsoil-min), De Martonne aridity index (IDM), total precipitation were investigated using long-term meteorological data (1960–2...

The Tibetan Plateau (TP) plays a crucial role in the climate change of China as well global change. It is therefore great practical significance to study vegetation and its dynamic changes for regional ecological protection. combination dry notable temperature disparities can lead intricate effects on region’s vegetation. However, there are few studies exploring complex diurnal variations growt...

Having an extreme topography and heterogeneous climate, the Upper Indus Basin (UIB) is more likely to be affected by climate change it a crucial area for climatological studies. Based on monthly minimum temperature (Tmin), maximum (Tmax) precipitation from nine meteorological stations, spatiotemporal variability of were analyzed monthly, seasonal, annual scales. Results show widespread signific...

We report on the self-catalyzed growth of InAs nanowires on InP substrate by metal-organic chemical vapor deposition. At a moderate V/III ratio, tapered nanowires are obtained, suggesting a strong surface diffusion effect. Dense twin faults are observed perpendicular to the nanowire growth direction due to the fluctuation of In atoms in the droplet originating from the surface diffusion effect....
