Water and fertilizer applications management should be improved due to scarce resources and environmental protection aspects. An analysis of crop yield production and profit maximization was conducted to determine the optimal water and nitrogen allocation. In this study, maize grain yields were predicted for 25 different amounts of irrigation water (350-1700 mm) and 46 different rates of nitrog...
In the south of Bahia state, a large part native Atlantic Forest areas has been modified for cultivation cocoa (Theobroma cacao). These crops are cultivated under shade canopy trees, system locally known as “cabruca” agroforestry system. This study aimed to evaluate relationship Odonata assemblages (adults and larvae) in farming identify relationships these species with local spatial environmen...

پیش بینی وضعیت اشتغال و بیکاری کشور به صورت کمی می تواند حدود بازار کار در چشم انداز 20 ساله را رقم بزند.در این مقاله با استفاده از مدل arima سهم اشتغال به سه بخش کشاورزی،صنایع و معادن و خدمات برای سالهای 1386-1404 پیش بینی می شود.نتایج نشان می دهد که سهم اشتغال بخشهای کشاورزی،صنایع و معادن و خدمات در طی 50 سال گذشته(1385-1336) به دترتیب کاهشی،افزایشی(با نرخ کم) و افزایشی بوده که پیش بینی انجا...
In this study, we propose an automatic diagnostic algorithm for detecting otitis media based on otoscopy images of the tympanic membrane. A total 1336 were assessed by a medical specialist into three groups: acute media, with effusion, and no effusion. To provide proper treatment care limit use unnecessary antibiotics, it is crucial to correctly detect membrane abnormalities, distinguish betwee...
BACKGROUND Various options exist for collecting biospecimens and biomarkers from cohort study participants, and these have important logistic, resource and scientific implications. Evidence on how different collection methods affect participation and data quality is lacking. This parallel-design randomised trial, the Link-Up Study, involved blood sample donation and other data collection among ...
