Timing of reproduction in birds is important for reproductive success and is known to depend on environmental cues such as day length and food availability. However, in equatorial regions, where day length is nearly constant, other factors such as rainfall and temperature are thought to determine timing of reproduction. Rainfall can vary at small spatial and temporal scales, providing a highly ...

The aim of the present study was to assess the pharmacokinetics and the efficacy of a shorter than usual 5-day quinine treatment given orally to children in Cameroon with malaria caused by Plasmodium falciparum. Quinine (8.3 mg of base per kg of body weight every 8 h) was administered as a 2% formiate salt syrup for 5 days to 30 children (age range, 0.55 to 6.7 years) with uncomplicated falcipa...

Crop water productivity modeling is an increasingly popular rapid decision making tool to optimize resource management in agriculture for the makers. This work aimed model, predict, and simulate crop (CWP) grain yields of both wheat maize. Climate datasets were collected over period from 1969 2019, including: mean temperature (Tmean), maximum (Tmax), minimum (Tmin), relative humidity (H), solar...

Due to the considerable biases in general circulation models (GCMs) simulation, bias correction methods are required and widely applied reduce model for impact studies. This study evaluated performance of two methods, quantile delta mapping (QDM) scaled distribution (SDM), generating high-resolution daily maximum temperature (Tmax) minimum (Tmin) projections Canada using latest GCMs from Couple...

In this work, the position-controlled growth of GaN nanowires on sapphire wafers and on N-polar GaN templates is presented using selective area vapor-liquid-solid growth in a metalorganic vapor phase reactor. Misoriented sapphire wafers and TMIn acting as surfactant are applied in order to achieve N-polar GaN buffer layers with high crystal and surface quality, suitable for a subsequent nano-pa...

Estimating actual vapor pressure (ea) without relative humidity (RH) data continues to draw research attention. One of the accurate ways estimate ea is through estimation dew point temperature (Tdew) from minimum (Tmin) or mean (Tmean). Two existing methods have been largely used ea. The first method (method I) assumes that Tdew close Tmin. other one II) adjusts Tmin with piecewise correction f...

Evapotranspiration is sensitive to climate change. The main objective of this study was examine the response reference evapotranspiration (ET0) under various change scenarios using artificial neural networks and Canadian Earth System Model Second Generation (CanESM2). Hargreaves method used calculate ET0 for western, central, eastern parts Prince Edward Island their two input parameters: daily ...

Air temperature is a key variable in wide range of environmental applications, including land–atmosphere interaction, climate change research and hydrology crop growth models, among others. The objective this study was to estimate daily maximum (Tmax) minimum (Tmin) temperatures, based on MODIS AQUA/TERRA land surface (LST), NDVI, extraterrestrial solar radiation precipitation data. Artificial ...

Since the 1950s, East Asian diurnal temperature range (DTR), defined as difference between daily maximum (Tmax) and minimum temperatures (Tmin), has gradually decreased. Precipitation changes have often been cited a primary cause of change. However, DTR change before 1950 its relationship with precipitation remain unclear. Here, we used newly developed China Meteorological Administration-Land S...

Abstract The study is conducted to examine the climate change impact on rice Crop Water Requirement (CWR) and Net Irrigation (NIR) using NASA Earth Exchange Global Daily Downscaled Projection (NEX-GDDP) coupled with CROPWAT 8.0 model. maximum temperature (Tmax), minimum (Tmin), rainfall projections for baseline (years 1981–2015) future 2030 2040) under Representative Concentration Pathway (RCP)...
