Hydraulic coefficients of a porous media such as hydraulic conductivity K(θ) and diffusivity D(θ) have a controlling role in the evaluation of groundwater flow and pollutant transport behavior. Therefore, successful porous media flow evaluation depends on the accurate determination of its hydraulic coefficients. But it is hard and time consuming to measure. Values for these coefficients accurat...
تعیین مدل تراوایی نسبی جهت استفاده در نرمافزارهای شبیهسازی مخزن یکی از بنیادیترین موضوعات در مطالعات مخزن است. در این مطالعه تراوایی نسبی آب- نفت با انجام آزمایشات در حالت ناپایا و در شرایط مخزن بر روی نمونه سنگهای کربناته سه مخزن B ،A وC با استفاده از روش JBN محاسبه شده و سپس با استفاده از این دادهها مدلهای مختلف تراوایی نسبی با یکدیگر مقایسه گردیده است.با بررسی نتایج آزمایشات، میتوان ن...
Capillary pressure (Pc) curves acquired using the Magnetic Resonance Imaging (MRI) technique, call GIT-CAP, have 70-100 data points. This extra data, when compared with traditional porous plate or centrifuge techniques, allows for the interpretation of more information from the Pc curve. In particular, the pore throat size and relative permeability can be extracted. The pore throat size can be ...

The failure to establish midline body pattern and left-right asymmetry properly is an important cause of congenital malformations. These defects are associated with considerable morbidity and mortality secondary to complex congenital heart defects (CHD), immune dysfunction caused by abnormalities of spleen position or number, gut malrotation, and midline central nervous system (CNS) defects. ZI...
پدیده نشت در سد های خاکی فقط از جنبه محاسبه دبی نشت مطرح نمی باشد، بلکه در پایداری ساختمان سد نقش بنیادی دارد. دقت در آنالیز پایداری با محاسبات نشت ارتباط مستقیم دارد. به طور طبیعی در مسائل نشت پایدار و ناپایدار در سد های خاکی می توان سه ناحیه کاملاً اشباع، نیمه اشباع و ناحیه خشک را از هم تفکیک کرد. در این تحقیق تأثیر نفوذ پذیری ناحیه غیر اشباع در موقعیت خط نشت و دبی نشت به صورت عددی و آزمایشگاه...
Diagnosis and Recommendation Integrated System (DRIS) norms were derived for crisphead lettuce (Lactuca sativa L.) from field fertility experiments conducted over the past 20 years on mineral and organic soils in Florida. Preliminary testing indicates that DRIS diagnoses generally agree with diagnoses using the sufficiency range approach, with the advantage of predicting the degree of nutrient ...
It is known that the three important parameters: resistivity, capillary pressure, and relative permeability, are all a function of fluid saturation in a porous medium. This implies that there may be a correlation among the three parameters. There have been many papers on the approach to inferring relative permeability from capillary pressure data. However the literature on the interrelationship...
•Patients with RASopathy present variable symptoms and have poor therapeutic options•We established 13 Drosophila models, each expressing a human variant•Models displayed variability in deregulated pathways, mirroring heterogeneity•Screening identified drug classes broadly active across subtypes RASopathies represent family of mostly autosomal dominant diseases that are caused by missense varia...
Dysregulated transforming growth factor TGF-β signaling underlies the pathogenesis of genetic disorders affecting connective tissue such as Loeys-Dietz syndrome. Here, we report 12 individuals with bi-allelic loss-of-function variants in IPO8 who presented a syndromic association characterized by cardio-vascular anomalies, joint hyperlaxity, and various degree dysmorphic features developmental ...
