the aim of this study was to evaluate the effect of different potassium (k) and nitrogen (n) concentrations in nutrient solution and their interaction on growth and quality of tomato transplants. a full factorial experimental design was carried out with three potassium concentrations (1.5, 3 and 6 meql-1) and three nitrogen concentrations (1.5, 3 and 6 meql-1) for 27 days after seed germination...

The leaf area-to-sapwood area ratio (LA:SA) is a key plant trait that links photosynthesis to transpiration. The pipe model theory states that the sapwood cross-sectional area of a stem or branch at any point should scale isometrically with the area of leaves distal to that point. Optimization theory further suggests that LA:SA should decrease toward drier climates. Although acclimation of LA:S...

background: to evaluate the association of apolipoprotein b (apob), apolipoprotein a (apoa), and apob/apoa ratio with the body fat indicators in patients with stable angina pectoris (sa). materials and methods: one hundred and twenty two participants aged 40-60 years old, with a mean age of 52.1 ± 7.2 years and sa, were recruited for the present study. body weight, height, and waist circumferen...

Preterm delivery increases the risk of infant mortality and morbidity, and therefore developing reliable methods for predicting its likelihood are of great importance. Previous work using uterine electromyography (EMG) recordings has shown that they may provide a promising and objective way for predicting risk of preterm delivery. However, to date attempts at utilizing computational approaches ...

In human visual cortex, the primary visual cortex (V1) is considered to be essential for visual information processing; the fusiform face area (FFA) and parahippocampal place area (PPA) are considered as face-selective region and places-selective region, respectively. Recently, a functional magnetic resonance imaging (fMRI) study showed that the neural activity ratios between V1 and FFA were co...

The Iowa landscape has been drastically transformed due to agricultural practices, causing population declines in many grassland bird species. Of greatest concern are bird species that are considered to be area sensitive. The Iowa State Preserve System is composed of tracts of prairies, wetlands, and woodlands that can provide habitat for many grassland bird species. This study provides an inve...
