Background: Small photon fields are increasingly used in modern radiotherapy especially in intensity modulated radiation therapy (IMRT) and stereotactic radiosurgery (SRS) treatments. Accurate beam profile and central axis depth doses measurements of such beams are complicated due to the electron disequilibrium. Hence the EBT2 (external beam therapy) Gafchromic film was used for dosimetry of sm...

Drought stress causes severe metabolic dysfunctions by formation of oxidative stress that may lead to damage in DNA, inactivation of enzymes, and lipid peroxidation. Plants have developed different morphological, physiological, and biochemical mechanisms to withstand the drought stress. Plant growth regulators (PGRs) are...

original article   evaluation of lymphadenopathy is of clinical significance as the underlying disease may range from a treatable infectious etiology to malignant neoplasm. the aim and objective of the present study was to evaluate palpable lymph nodes of population working in small to medium scale industries represented as group a by fine needle aspiration cytology (fnac) and to compare the re...

background: many studies reported that follicle size has an essential role in developmental potential of oocytes. also, the brilliant cresyl blue (bcb) test is one of the most important criteria in selection of more competent oocytes. objective: selection of developmentally competent bovine oocytes. materials and methods: a total of 1730 bovine cumulus oocyte complexes (cocs) were recovered fro...

We present a method to compute and visualize the curvature and torsion scalar fields derived from a vector field defined on a multi-block curvilinear grid. In order to compute the curvature and torsion fields, we define a uniform Cartesian grid of points in the volume occupied by the curvilinear grid and interpolate from the curvilinear grid to the Cartesian grid to get the vector field at the ...

An integral-differential equation is derived for the self-consistent (effective) field in the medium consisting of many small bodies randomly distributed in some region. Acoustic and electromagnetic fields are considered in such a medium. Each body has a characteristic dimension a ≪ λ, where λ is the wavelength in the free space. The minimal distance d between any of the two bodies satisfies th...

Background: Adiponectin is an adipocytokines which is secreted from the adipose tissue of human and domestic animals. No information is available regarding the follicular fluid adiponectin concentrations in dairy cows. Therefore, the aim of the present study was to determine the follicular fluid adiponectin concentrations in different-sized follicles in the luteal phase of the estrous cycle in ...
