objective: a secondary ectopic pregnancy is defined as continuing development of a fetus in the abdominal cavity after rupture of the uterine wall, which may be associated with a history of trauma. methods: a cat was referred to the veterinary teaching hospital of the university of tehran with history of anorexia and vaginal bleeding. in clinical examination some masses werepalpated in abdomina...

introduction: dacryocystorhinostomy (dcr), a popular surgical procedure, has been performed using an endoscopic approach over recent years. excellent anatomical knowledge is required for this endoscopic surgical approach. this study was performed in order to better evaluate the anatomical features of the lacrimal apparatus from cadavers in the isfahan forensic center as a sample of the iranian ...

In a prospective survey, 200 cases of operated chronic dacryocystitis were divided into three groups according to the kind of operation, and the respective results are as follows: Group I includes 100 cases in whom the lacrimal bone was removed (8mm x 8mm) and a 6mm diameter catheter was used (as a duct between the lacrimal sac and nasal cavity). The recurrence rate within one year was 24 ...

Removal of sulfur from gasoline is one of the major processes in refineries. Designing of removal process requires phase equilibrium data of the sulfur with various hydrocarbon systems. 3-Methylthiphene is an organic sulfur compound found in gasoline. In the present work VLE data of 3-Methylthiophene with various hydrocarbons were modeled using genetic algorithm. VLE data were modeled using Wil...

Solid-liquid equilibria for binary mixtures of {Methyl palmitate (1) + Naphthalene (2)} were measured using differential scanning calorimeter (DSC). Simple eutectic behaviours for this system are observed. The experimental results were correlated by means of the NRTL, Wilson, UNIQUAC and ideal models. The root-mean-square deviations of the solubility temperatures for all measured data vary from...

In order to reduce global CO2 emissions, capture based on absorption in an amine/water mixture is established method. To develop such processes, correct physicochemical properties like densities and viscosities are important.The first objective of this work explore mathematical correlations for fitting viscosity data aqueous Monoethanolamine (MEA) Methyldiethanolamine (MDEA). A second evaluate ...
