The influence of VAM fungi and bacterial biofertilizer (BBF) with 50% reduction in the recommended dose of (N and P) chemical fertilizers on leaf quality traits of mulberry variety (S-13) and its impact on silkworm (PM ? NB4D2) growth and cocoon characters were studied under semi-arid conditions. Four different treatments were imposed i.e., T1: Control (only 100% NPK); T2: VAM (50% cut in P); ...

We test the impact of a reciprocal adult labor program, Ajuda Mútua (AM), on child and schooling. AM was introduced into province Nampula in Mozambique, an area where farm production relies labor, potentially due to financial market failures. Using difference differences, we estimate that reduces by eight percentage points. argue providing low-cost increasing productivity. benchmark results aga...

Cleft Palate (CP) assessments based on phonetic transcription are the "gold standard" therapy outcome measure, despite reliability difficulties. Here we propose a novel perceptual evaluation, applied to ultrasound-visual biofeedback (U-VBF) therapy and therapy using visual articulatory models (VAMs) for two children with repaired submucous CP. Three comparisons were made: post VAM, post U-VBF a...

in order to understanding of the vam effects on functions and nutrition of the corn, a research was conducted in agricultural research center of safi abad, khouzestan. the experiment was carried out based randomized complete block design at four replications. the treatments contain mycorrhiza fungi and phosphorous includes: a: phosphorus according to soil test. b: vam + phosphorus according to ...

A virtual environment (VE) has been designed for functioning as a threedimensional interface to a repository of images and sounds. This paper attempts to study design interface in VEs. This study first examines the characteristics of VEs. The difference between physical and virtual environments is also studied. The relationship between both is classified as three types, i.e. complement, replace...

Internet access services based on cellular technology have grown significantly over the years. Regarding total number of users, Brazil does not have global stand-out participation yet. However, recent data reveals significant growth in the adoption of those services in Brazil. This study intends to assess the relative influence of the relevant factors that affect the adoption of mobile Internet...

In this policy brief we argue that there is little debate about the statistical properties of value-added model (VAM) estimates of teacher performance, yet, despite this, there is little consensus about what the evidence about VAMs implies for their practical utility as part of high-stakes performance evaluation systems. A review of the evidence base that underlies the debate over VAM measures,...
