We use hedonic analysis of home transaction data from the Minneapolis–St. Paul metropolitan area to estimate the effects of proximity to open space on sales price. We allow the effects of proximity to vary with demographic and location-specific characteristics and include fixed effects to control for observed and unobserved neighborhood characteristics. We find that the value of proximity to op...
Migration is considered a pathway out of poverty for many rural households in developing countries. National policies can discourage households from exploiting external employment opportunities through the distortion of capital markets. Studies in China show that the presence of state and collectively owned land creates inefficiencies in the labor market. We examine the extent restrictions on l...
Neuronal cell death at late stages of Alzheimer’s disease (AD) causes the release cytosolic proteins. One most abundant such proteins, glyceraldehyde-3-phosphate dehydrogenase (GAPDH), forms stable aggregates with extracellular amyloid-β (Aβ). We detect these in cerebrospinal fluid (CSF) from AD patients levels directly proportional to progressive AD. found that GAPDH a covalent bond Q15 Aβ is ...
cases found that 11 patients (61.1%) had a homozygous deletion of a 200‐kb fragment of the DPY19L gene, two (11.1%) had a homozygous nonsynonymous mutation in exon 8 (p.R298C), one (5.6%) had a homozygous new splice site mutation at the junction of exon‐intron 16 (c.1579_1580 + 4delAGGTAAinsTCAT), and four (22.2%) had no mutations in DPY19L2, SPATA16, or PICK1.4 In humans, the DPY19L2 gene is l...
BACKGROUND Periventricular heterotopia (PH) is an etiologically heterogeneous disorder characterized by nodules of neurons ectopically placed along the lateral ventricles. Most affected patients have seizures and their cognitive level varies from normal to severely impaired. At present, two genes have been identified to cause PH when mutated. Mutations in FLNA (Xq28) and ARFGEF2 (20q13) are res...
وسعت مراتع ایران از یکسو و وابستگی دامداری به این منابع از سوی دیگر بر نحوهی مدیریت مراتع تاثیر گذاشته و سبب شده است که مدیریت آن بهگونهای باشد تا مناسبترین اندازهی واحد بهرهبرداری در چارچوب مدیریت علمی مراتع و با توجه به ارتباط انسان، دام و مرتع با هدف افزایش درآمد، پایداری بهرهبرداری از مراتع و بازگشت سرمایه انتخاب شود. در تحقیق حاضر هدف انتخاب نظام بهرهبرداری با بالاترین اولویت د...
