this study investigated the effectiveness of heat treatment (50°c, 60°c and 70°c for 1 h and 2h at 75-80% rh) and cold treatment (0°c and-5°c for 24h and 48h) in the control of storage pests in zahedi and piyarom dates. before and after each treatment, the number of surviving adults, larvae, pupae and eggs were recorded and the percentage of infestation was calculated. the dates were treated at...

The performance of the adaptive projection receiver (PR), a recently proposed joint detector for CDMA with error control coding, is investigated. It is shown that the adaptive version of the PR performs better than the algebraic PR. A close approximation of the error probability for the adaptive PR is derived. The performance improvement of the adaptive PR, which is of the order of 1-2dB in Eb=...

While the conditions for successful technology integration finally appear to be in place including ready access to technology, moderately trained teachers, and a favorable policy environment, high-level technology use is still surprisingly low. This suggests that additional barriers, specifically related to teachers’ pedagogical beliefs, may be at work. Previous researchers have noted the influ...

Graph-based semi-supervised learning methods have shown to be efficient and effective on network data by propagating labels along neighboring nodes. These methods can also be applied to general data by constructing a graph where the nodes are the instances and the edges are weighted by the similarity between feature vectors of instances. However, whereas a natural network is often sparse, a net...

OBJECTIVE The aim of this study was to understand how and why young people drink less or not at all when with their peers. Understanding the subjective experiences of moderate or non-drinkers may help identify protective processes facilitating resilience to cultural norm and influences that encourage excessive alcohol consumption among young people. DESIGN Semi-structured interviews were cond...

Ashwagandha, commonly known as the Indian Ginseng (Withania somnifera) is an ingredient in many herbal preparations used for healing various ailments. It is cultivated in semi-arid regions of India as rain-fed crop. The response of this crop (cv. JA-134) to progressive soil moisture deficit on growth, physiology and content of phytochemicals was studied. At the end of treatment period, soil wat...

Two sets of rate coefficients for low-energy inelastic potassium-hydrogen and rubidiumhydrogen collisions were computed for each collisional system based on two model electronic structure calculations, performed by the quantum asymptotic semi-empirical and the quantum asymptotic linear combinations of atomic orbitals (LCAO) approaches, followed by quantum multichannel calculations for the non-a...
