A cultura do amendoim pode fazer parte sistema de rotação culturas anuais no estado Mato Grosso, o mais importante na produção grãos país. Para tanto, devem ser desenvolvidas cultivares adaptadas e produtivas para os produtores. Este trabalho teve como objetivo avaliar as características agronômicas genótipos região sudeste Grosso. O experimento foi desenvolvido ano agrícola 2021/22, área exper...
Sayısız araştırma, öğretmen ve öğrencilere ait bilişsel üstbilişsel süreçlerin öğrencilerin akademik başarısında kritik bir rol oynadığını göstermektedir. Çalışma öncelikle öğretmenlerin kendi, kendi öğrencilerinin bilişine dair hedef, izleme kontrol süreçlerini içeren “eğitimde çok düzeyli düzenleme modeli” önermeyi amaçlamıştır. İkinci olarak, önerilen model çerçevesinde envanteri (EÜDE)”nin ...
Abstract We present a thermal history of the Kedougou Kenieba Inlier (eastern Senegal), western-central outcropping part West African Craton, based on 40Ar/39Ar analyses performed hornblende, biotite, and K-feldspar minerals from Paleoproterozoic plutonic rocks. age spectra obtained for hornblendes biotites range between 2055 ± 26 2028 ± 28 Ma, in very good consistency. They suggest that magmat...
Abstract Climate change has adverse impacts on Arctic natural ecosystems and threatens northern communities by disrupting subsistence practices, limiting accessibility, putting built infrastructure at risk. In this paper, we analyze spatial patterns of permafrost degradation associated risks to due loss bearing capacity thaw subsidence in regions the Arctic. Using a subset three Coupled Model I...
Conservation and natural resource management are frequently hampered by poor understanding of how species distributions have changed over time. Species Distribution Models (SDMs) correlate known occurrences with environmental variables to predict a species’ potential range. These models can then be projected unsurveyed areas or time periods overcome gaps in data on distribution. The eastern quo...
PurposeTo determine the reliability of subjective and objective quantification mitral annular calcification (MAC) in elderly patients with severe aortic stenosis, to define quantitative sex- age-related reference values MAC, correlate MAC valve disease.MethodsIn this retrospective, IRB-approved study, we included 559 (268 females, median age 81 years, inter-quartile range 77–85 years) stenosis ...
تکنیک تداخل سنجی راداری(d-insar) به عنوان یک روش مناسب جهت آشکار سازی تغییرات بوجود آمده در سطح زمین می باشد. محاسبه جابجایی های رخ داده در سطح زمین با استفاده از تکنیک d-insar شامل قابلیت های منحصر بفردی در ابعاد هزینه، زمان و دقت نسبت به تکنیکهای دیگر سنجش است. در مطالعه حاضر نرخ و دامنه فرونشست در سطح دشت مرند، با استفاده از تکنیک d-insar در بازه زمانی خرداد 1383- بهمن 1389 محاسبه و تعیین گش...
i) BB16 (1) provide no evidence that J15’s (2) cost, demand flexibility, or electrification assumptions are aggressive. Further, J15’s cost ranges are neither confidence intervals nor narrow (e.g., underground storage capital costs span over an order of magnitude), and, by far, most technologies proposed are commercial or extant for years. ii) BB16 (1) provide no evidence that J15’s (2) results...
Synoptic weather and larger scale circulation patterns are closely coupled have a major influence on regional extreme events. This study examines the role of circulations meteorology events for present future years over Asia with WRF model driven by HadGEM2 global boundary conditions that includes RCP4.5 scenarios based bicentennial transient simulation. The analysis was derived from 40 outputs...
