Consider small particles of varying size being transported by a fluid. If we allow these particels to coalesce their evolution may be described by the coagulation model ft + p m .∇xf = Q(f) . Here f denotes the particle density f(t, x, m, p) of particles with mass m ∈ R+, momentum p ∈ R3, at time t > 0 and position x ∈ R3. For a general class of collion operators Q we prove existence of solutio...

sodium iodide-131 is administrated for treatment of hyperthyroidism and thyroid cancer. iodine-131 has multiple routs of excretion (urine, saliva, sweat, milk, feces, exhalation) from the body. patients receiving sodium iodide-131 therapy exposes other persons and the environment to unwanted radiation and contamination. the major source of radiation dose from administration of iodine-131 is ext...

background: the dose rate distribution delivered by a low dose rate 137cs pellet source, a spherical source used within the source trains of the selectron gynecological brachytherapy system, was investigated using the mcnp4c monte carlo code. materials and methods: the calculations were performed in both water and plexiglas and the absolute dose rate distribution for a single pellet source and ...

This article discusses the perioperative management of antithrombotic therapy and is part of the American College of Chest Physicians Evidence-Based Clinical Practice Guidelines (8th Edition). The primary objectives of this article are the following: (1) to address the perioperative management of patients who are receiving vitamin K antagonists (VKAs) or antiplatelet drugs, such as aspirin and ...

BACKGROUND Application of less toxic normoxic polymer gel of N-isopropyl acrylamide (NIPAM) for radiation therapy has been studied in recent years. AIM In the current study the optical and NMR properties of NIPAM were studied for radiation therapy dosimetry application. MATERIALS AND METHODS NIPAM normoxic polymer gel was prepared and irradiated by 9 MV photon beam of a medical linac. The o...

The investigation was carried out with the aim to identify specific yield limiting nutrients through response of rice nutrient omission in pot culture under completely randomized design 3 replications and 11 treatments during kharif season 2017 demonstrate optimum use identified wheat crop at field level Kondagaon district rabi 2017-18. were formulated by keeping one treatment application all o...

Dissipation and transformation of cyantraniliprole, a new diamide class insecticides, were investigated under greenhouse conditions, using snapdragon (Antirrhinum majus) as the model plant. cyantraniliprole in treated leaves was found to be dependent upon application methods (foliar spray versus soil drench) doses (high low dose), with parent insecticide being major residue at various sampling ...

high-dose extended-interval dosage (hded) regimen of aminoglycosides is now considered as the standard dosage strategy in sepsis. although safety and efficacy of this dosing regimen is well studied, but new experiments show increased the risk of resistance development associated with %t>mic less than 60% of the dosing interval following extended interval dosing. moreover, limited information is...

background: the aim of this study was to measure137cs levels in soil and brick samples to set the baseline data and an indicator of fallout radioactivity for this part of the world. this study will help to probe, if there is any health threat posed by 137cs exposure to the residents of the area. materials and methods: twenty five samples of soil and 6 samples of bricks were collected from diffe...
