China is the largest peanut producer in the world and peanut therefore an essential economic product earning significant income for China’s farmers. Major provinces for peanut production are located in the middle and eastern provinces. In these regions, drought stress between germination and pod setting, could be severe and yield decline because of uneven rainfall and climate variability. Four ...
BACKGROUND Assessment of patients with suspected interstitial lung disease (ILD) includes surgical lung biopsy (SLB) when clinical and radiological data are inconclusive. However, cryobiopsy is acquiring an important role in the ILD diagnostic process. The objective of this study was to evaluate the diagnostic yield, safety and economic costs of the systematic use of cryobiopsy in the assessmen...
Trimax is a new insecticide from Bayer CropScience specifically for use on cotton for control of major sucking/piercing insects in cotton. In addition, significant yield enhancement benefits have been observed even in situations without economic insect thresholds. However, information is lacking on how Trimax affects plant growth and thereby enhances yield. The current study was designed to und...
Experiments were conducted with two commonly grown mungbean varieties viz., M-28 and 6601, in open top chambers and ambient field conditions with the aim of ascertaining the effects of air pollution on yield. The 8-h daily mean ozone concentrations were 41-73 nl litre. A considerable reduction of 47.06% and 51.12% in seed yield for M-28 and 6601, respectively were found which are substantially ...
climate change is a phenomenon that has made the most concern in communities and decision making centers. this phenomenon has important effects on different aspects of human life. one of the most important crops that are affected by climate change is wheat. accordingly, data and information of northern khorasan have been used to study the effects of climate change on rain-fed wheat yield. for t...
to study the effect of planting pattern and water quantity on potato yields under drip irrigation, this research was conducted using a split plot based on a randomized complete block design with four replications in three regions (mashhad, ardebil and damavand, iran) during 2003-2004. nine treatments were used. the main-plots were three levels of irrigation: 100%(i1), 80%(i2), and 60%(i3) of cr...
The existence of common factors in international bond markets is an important cause for modelling different term structures of interest rates jointly. This paper investigates the common factors of US and UK treasury yields in the period of 1983 to 2012. A principal component analysis motivates the type of joint ATSM for modelling the yield curves of two distinct economies. In sum, two common fa...
49 Introduction Most yield loss is caused by random defects and systematic process errors. For the 130 nm design-rule generation, random defects and parametric process errors are roughly equal contributors to yield loss. At the 90 and 65 nm nodes, parametric losses are expected to dominate. Factory managers will be forc e d to make an economic trade-off between yield and density in order to ach...
