Common methods to determine the soil infiltration need extensive time and are expensive. However, the existence of non-linear behaviors in soil infiltration makes it difficult to be modeled. With regards to the difficulties of direct measurement of soil infiltration, the use of indirect methods toestimate this parameter has received attention in recent years. Despite the existence of various th...
Epidermal proliferation, inflammatory changes and microvascular augmentation are prominent features of chronic cutaneous psoriatic lesions. The objective of this study was the investigation of blood and lymphatic microvascular changes in relation to epidermal changes and inflammatory infiltration in dermis. Immunohistochemical analysis with antibodies to CD34, podoplanin, vascular endothelial g...
soil infiltration characteristics affect the design, evaluation and management of furrow irrigation over afield. on the other hand, different variables influence furrow infiltration, making infiltration modeling for afield a complex process. this study was conducted to investigate the direct and indirect effects of allvariables affecting furrow infiltration. the blocked furrow method was used t...
BACKGROUND Infiltration is a key process in determining the water balance, but so far effects of earthworms, soil texture, plant species diversity and their interaction on infiltration capacity have not been studied. METHODOLOGY/PRINCIPAL FINDINGS We measured infiltration capacity in subplots with ambient and reduced earthworm density nested in plots of different plant species (1, 4, and 16 s...
OBJECTIVES The objectives of our study were as follows: 1) to analyze the prognostic value of macrophage infiltration in primary IgA nephropathy (IgAN) and 2) to study the relationship between macrophages and other factors associated with the development of renal fibrosis, including mast cells, TGF-β1, α-SMA and NF-kB. METHODS We analyzed 62 patients who had been diagnosed with IgAN between 1...
DDesigned and undersigned fires in rangelands affect vegetation and soil, and then are necessary to give enough knowledge about them. Infiltration is one characteristic that have predict had affected by fire but had not studied enough yet. So spot fire have been seen in Artemisia aucheri type in Charat sub watershed at Mazandaran province, in this research were investigated primary, final infil...
OBJECTIVE To investigate the significance of the dynamic contrast enhanced magnetic resonance imaging (DCE-MRI) parameters of diffuse spinal bone marrow infiltration in patients with hematological malignancies. MATERIALS AND METHODS Dynamic gadolinium-enhanced MR imaging of the lumbar spine was performed in 26 patients with histologically proven diffuse bone marrow infiltration, including mul...
Closed-end furrows are commonly used to irrigate crop in northern part of China. The irrigation performance of furrow in this area is often low. The objectives of this paper are to verify reliability of infiltration parameters and Manning roughness estimated with SIPAR_ID software and present an optimized method for design of closed-end furrow system. The study consisted of field experiments an...
