Botrytis cinerea is one of the most common plant pathogenic fungi that affects a wide range of greenhouse horticultural products and decreases their market value. B. cinerea can strongly decrease yield and post-harvest quality through latent infections. It is a highly water dependent fungus and a certain leaf wetness duration seems necessary for spore germination. However, during germination be...
We consider adaptive mortar edge element discretizations in the numerical solution of the quasi-stationary limit of Maxwell’s equations, also known as the eddy currents equations, in three space dimensions. The approach is based on the macro-hybrid variational formulation with respect to a geometrically conforming, non overlapping decomposition of the computational domain. Using adaptively gene...
stable pile depth in the Snowy River study (SKM 2005) is outlined. The inputs used in the run of the LLP99 model were: • single soil layer, • very high flexural stiffness of pile (1,000,000 kN/m). • pile width = 0.3 m (i.e. wooden pile), • shear strength in the absence of lateral stress (for unconsolidated sand 150 kN/m was used), • effective unit weight of soil (15 kN/m), • active lateral effe...
Abstract. For understanding Arctic climate change, it is critical to quantify and address uncertainties in data records on clouds radiative fluxes derived from long-term passive satellite observations. A unique set of observations collected during the PS106 expedition research vessel Polarstern (28 May 16 July 2017) by OCEANET facility, exploited here for this purpose compared with CERES SYN1de...
تحقیقات صورت گرفته در دهه های گذشته نشان می دهد که شرایط آب و هوایی اثر مهمی بر عملکرد روسازی های آسفالتی دارد. عوامل محیطی بیرونی مانند بارش، دما، سیکل های ذوب و یخ و سطح آب زیرزمینی بر روی تمام خرابی های روسازی تاثیر می گذارند. با پیدایش ابزارهای محاسبه سریع، توجه به این اثرات که در گذشته به دلیل طولانی بودن محاسبات و نبود ابزارهای مناسب برای تحلیل و طراحی، نادیده گرفته می شد، بیشتر شد. به ه...
چکیده مقدمه :در حال حاضر حوادث ناشی از کار به عنوان سومین عامل مرگ و میر در جهان ، دومین عامل مرگ و میر در ایران و یکی از مهمترین ریسک فاکتورهای مهم بهداشتی ،اجتماعی و اقتصادی در جوامع صنعتی و در حال توسعه می باشد. هدف از این مطالعه، بررسی حوادث ناشی از کار با استفاده از شاخص های osha در صنعت چوب و کاغذ مازندران بود. مواد وروش کار:این مطالعه ازنوعطولیبود.برای بررسی حوادث ناشی ازکار، فرمهای ثبت ...
During Ocean Drilling Program (ODP) Leg 204, we will drill a transect of sites through the gas hydrate stability zone on the southern part of Hydrate Ridge on the Cascadia accretionary margin offshore Oregon. Massive hydrates are present at the seafloor there, and high-resolution threedimensional seismic data indicate a complicated subsurface plumbing system. The transect will cover two distinc...
Brown eye spot (Cercospora coffeicola) is one of the main fungal diseases coffee, leading to a significant drop in crop productivity and beverage quality Brazil. The identification potential risk areas for development disease provides promising information management pathogen. This study aimed elaborate an agroclimatic zoning incidence brown on coffee under climate change scenarios, as suggeste...
In British Columbia, Canada, over a century of forest harvesting has severely degraded many streams and as a consequence has contributed to the impairment of some other valuable forest resources, especially salmon. Recognition of the problem of land-use alteration on stream channels resulted in efforts to protect and restore stream channels to bring back stream and riparian ecosystems to their ...
