BACKGROUND Limited data on a short series of patients suggest that lymphocytic enteritis (classically considered as latent coeliac disease) may produce symptoms of malabsorption, although the true prevalence of this situation is unknown. Serological markers of coeliac disease are of little diagnostic value in identifying these patients. AIMS To evaluate the usefulness of human leucocyte antig...
مقدار تبخیر و تعرق حقیقی مزرعه یونجه واقع در باجگاه بوسیله روش تعادل آبیاری در 9 کرت آزمایشی و دولیسمتر از نوع وزنی بمنظور تعیین آب مصرفی گیاه یونجه تعیین شد. در طول مدت آزمایش مقدار آب موجود در خاک بوسیله نمونه برداری وزنی از خاک و دستگاه نوترون متر تعیین و مقدار تشعشع رسیده از خورشید بزمین و ساعات آفتابی روز نیز اندازه گیری شد. مقدار تبخیر و تعرق پتانسیل بوسیله روشهای modified blaney-criddle ...
مقدمه و هدف: مطالعات اندکی در کشورهای غرب آسیا در مورد شیوع بیماری سلیاک صورت گرفته است و در ایران تنها یک مطالعه به بررسی شیوع بیماری سلیاک در اهداء کنندگان خون پرداخته است. هدف این مطالعه بررسی شیوع بیماری سلیاک در شهر ساری است. مواد و روش ها: این مطالعه توصیفی در سال 1382 روی 1438 نفر (686 مرد و 752 زن، متوسط سن 35.5 سال از محدود سنی 18-66 سال) افراد اهل شهر ساری به روش تصادفی لایه ای انجام ...
Characteristics of Ponds Used by Breeding Mottled Ducks on the Chenier Plain of the Texas Gulf Coast
Mottled ducks Anas fulvigula are nonmigratory and primarily depend on habitats associated with coastal marshes of the Gulf Coast for their entire life cycle. Much of remaining available coastal marsh habitats of the Texas Gulf Coast are managed by state and federal agencies. The Texas Gulf Coast breeding population of mottled ducks has recently declined dramatically. To aid in development of ma...
Armoring shorelines to prevent erosion is a long-standing global practice that has well-documented adverse effects on coastal habitats and organisms. A relatively new form of shoreline protection, referred to as hybrid stabilization, incorporates created marsh in combination with a stabilizing structure such as a low-profile stone sill and is being implemented in many US coastal states as a mea...
—Little is known about the population status of many marsh-dependent birds in North America but recent efforts have focused on collecting more reliable information and estimates of population trends. As part of that effort, a standardized survey protocol was developed in 1999 that provided guidance for conducting marsh bird surveys throughout North America such that data would be consistent amo...
Coastal highways along narrow barrier islands are vulnerable to flooding due ocean and bay-side events, which create hazardous travel conditions may restrict access surrounding communities. This study investigates the vulnerability of a segment highway passing through Pea Island National Wildlife Refuge in Outer Banks, North Carolina, USA. Publicly available data, computational modeling, field ...
We performed pollen analysis and accelerator mass spectrometry (AMS) radiocarbon dating on cored sediments (KS0412-3) from Kashibaru Marsh, located in the western part of the Sefuri Mountains in northern Kyushu, southwestern Japan, to investigate environmental change around the marsh. Sediment accumulation began in this marsh around cal AD 1200 and continued with an estimated average sedimentat...
