Background & objective: Breast cancer is the most common cancer in women. Lymph node involvement is the most important prognostic factor in this cancer. Since there is no consensus about the relationship between lymphocytic infiltration and breast cancer prognosis, this study was conducted to investigate the correlation between stromal lymphocytic reaction and lymph node involvement in grade 1 ...
The variation in moisture content between subsequent irrigations determines the use of infiltration equations that contain representative physical parameters soil when irrigation begins. This study analyzes reliability hydrodynamic model to simulate advanced phase border irrigation. For solution model, a Lagrangian scheme implicit finite differences is used, while for infiltration, Kostiakov eq...
Infiltration is the process by which water enters the earth’s surface. Although contribution of soil water to total water present on earth surface is negligible, but it is of prime importance for plant life. Very recently, dimensionless form of Kostiakov equation was proposed for precise estimation of Kostiakov model parameters. The present paper is an assessment of accuracy of proposed dimensi...
Virus-induced gene silencing (VIGS) is an attractive tool for determining gene function in plants. The present study constitutes the first application of VIGS in S. pseudocapsicum, which has great ornamental and pharmaceutical value, using tobacco rattle virus (TRV) vectors. Two marker genes, PHYTOENE DESATURASE (PDS) and Mg-chelatase H subunit (ChlH), were used to test the VIGS system in S. ps...
PURPOSE Computed tomography (CT) has become popular in the diagnosis of acute pyelonephritis (APN) and its related complications in adults. The aim of this study was to investigate the relationship between uncommon CT findings and clinical and laboratory data in patients with APN. MATERIALS AND METHODS From July 2009 to July 2012, CT findings and clinical data were collected from 125 female p...
OBJECTIVES The purpose of this study was to determine interobserver agreement for interpretation of magnetic resonance imaging (MRI) examinations of arrhythmogenic right ventricular dysplasia (ARVD) and to determine sensitivity and specificity of fat detection versus functional parameters measured by MRI. BACKGROUND The interobserver variability of MRI and the relative importance of different...
infiltration rate is one of the most important soil physical parameters and is a basic input data in irrigation and drainage projects. although, a number of theoretical or experimental based equations are presented to describe this phenomenon but the evaluation of some new sciences such as artificial neural networks, for prediction of the phenomenon can be investigated. generally, the infiltrat...
Soil heterogeneity and the lack of detailed site characterization are two ubiquitous factors that render predictions of flow and transport in the vadose zone inherently uncertain. We employ the Green–Ampt model of infiltration and the Dagan– Bresler statistical parameterization of soil properties to compute probability density functions (PDFs) of infiltration rate and infiltration depth. By goi...
At present, soil surface characteristics (SSC) are recognised as key parameters controlling infiltration rates, runoff generation and erosion. Microtopography of surface among SSC is the main one. The work presented in this paper is based on a set of digital elevation models (DEMs) supplied by two different methods: Laser roughness-meter and photogrammetry method. We used two maquettes. The use...
