Few investigations have examined the structural controls of bark on its water storage and influence stemflow, despite being considered a critical component that determines time magnitude this process. This study seeks to answer question: Do absorbability wettability estimates correlate with stemflow yield? We hypothesized (1) are correlated, is, greater implies wettability, (2) high rates has s...
Atmospheric rainfall is one of the major sources water and nutrient inputs in forest stands. Understanding atmospheric partitioning hydrochemical fluxes stands critical for management monitoring regional pollution, especially high N deposition regions. In this study, annual collections were implemented to investigate partitioning, element concentrations, an evergreen coniferous (ECF) stand, a d...
زمینه و هدف : نارسایی مزمن کلیه و همودیالیز، باعث تغییرات عمده در سبک زندگی بیماران شده که کیفیت زندگی آنها را تحت تاثیر قرار می دهد. هدف این پژوهش، بررسی کیفیت زندگی در بیماران همودیالیزی می باشد. روش کار : این پژوهش توصیفی تحلیلی در بیمار ان همودیالیزی درسال 1391 انجام گرفت. تعداد 245 بیمار از 4 بیمارستان آموزشی وابسته به دانشگاه علوم پزشکی تبریز و مراغه بر اساس روش نمونه گیری در دسترس به ع...
The size of stemflow infiltration areas around the boles trees is currently a topic interest and debate within hydrologic community. There gap in our knowledge many wooded ecosystems need for more than few studies that have examined directly. Hence, this field study was specifically undertaken to mitigate existing data by providing direct measurements from high stemflow-producing American beech...
Stemflow from Japanese red cedar (Cryptomeria japonica) enters forest soil at a low pH. We evaluated the responses of the root system of Japanese red cedar saplings to acidic conditions, used to simulate this situation, in two different growth media, a brown forest soil (BS) and a Yahagi sand (YS). Soils were acidified by the addition of solutions at pH 2.0, 3.0 and 5.5 (control). Root morpholo...
The interception of precipitation by plant canopies can alter the amount and spatial distribution water inputs to ecosystems. We asked whether canopy could locally augment shrubs their crowns funneling (freshwater) as stemflow bases, in a wetland where relict overstory trees are dying persisting only grow on small hummocks that sit above mesohaline floodwaters. Precipitation, throughfall, were ...
