Increasing crop biodiversity, such as by adjacent managed crops, is recognized an effective biological control measure. However, few studies have focused on the mechanisms involved in how crops increase natural enemy populations, leading to reduced pest numbers. This study investigated hypothesis that cotton grown sorghum would positively influence feeding and oviposition preferences of ladybug...

Background To determine whether IMRT could decrease skin toxicities in patients undergoing PMRT of chest wall, supra/infraclavicular (SCV), and internal mammary nodes (IMN) as compared to conventional technique. Materials and Methods Between 2009 and 2013, 106 patients treated with IMRT and 138 treated with conventional technique were followed up regularly. The skin toxicities were graded acc...

مراتع حدود نیمی از خشکی های جهان را در بر دارند و پوشش گیاهی آن در نتیجه تأثیر متقابل محیط و موجودات زنده به وجود آمده است و به عنوان یک اکوسیستم طبیعی مدیریت می شوند. علاوه بر مراتع، راه ها در عصر حاضر نیز از اجزا مهم و زیرساخت های اصلی زندگی نوین و توسعه کشورها به شمار می روند. جاده ها ساخته دست بشر هستند و جوامع گیاهی کنار جاده تحت تأثیر ساخت و ساز قرار دارند. پوشش "رودرال" به مجموعه ای از پ...

Agricultural practices can result in differences in organic matter (OM) and agricultural chemical inputs in adjacent ditches, but its indirect effects on OM composition and its inherent consequences for ecosystem functioning remain uncertain. This study determined the effect of agricultural practices (dairy farm grasslands and hyacinth bulb fields) on OM degradation by microorganisms and invert...

While auditory cortex in non-human primates has been subdivided into multiple functionally specialized auditory cortical fields (ACFs), the boundaries and functional specialization of human ACFs have not been defined. In the current study, we evaluated whether a widely accepted primate model of auditory cortex could explain regional tuning properties of fMRI activations on the cortical surface ...

Abstract The study of Gaussian Markov Random Fields has attracted the attention a large number scientific areas due to its increasing usage in several fields application. Here, we consider construction from graph and positive-definite matrix, which is closely related problem finding Maximum Likelihood Estimator covariance matrix underlying distribution. In particular, it simultaneously required...

The organo-phosphate experimental nematicide, O-ethyl S,S-di-sec-butyl phosphorodithioate (FMC 67825), provided yield increases of corn comparable to carbofuran. Both the emulsifiable concentrate and granular formulations of FMC 67825 were equally effective. The evaluations, duplicated in two adjacent fields, clearly demonstrated the importance of the type of plant pathogenic nematodes infestin...
