  Community satisfaction has often been linked to the level of satisfaction with a community’s infrastructure, job opportunities and social support networks. Apart from concern over population decline, there is another important reason for wanting to have a better understanding of what factors influence “community satisfaction.” Community development practitioners, community leaders, and other local stakeholders see “community cohesion”, “a strong sense of community” and similar concepts as having both intrinsic and instrumental value associated with their work and responsibilities. Yet, most empirical analyses of community and residential satisfaction have focused on only one aspect of the available theory to predict the satisfaction of individuals. However there are some similarities in those definitions which stems from this notion that there is a core in all of those interpretations. Those cores need to be portrayed clearly to make this concept more understandable in multidisciplinary activities. Residential satisfaction reflects the degree to which individuals’ housing needs are fulfilled. RS is a subjective dependent variable which depends on many physical and social parameters. However, the propriety of those parameters could vary for different people with different social cultural and professional back grounds. Housing is a mixed used element that satisfies several needs. The failures of many housing projects stems from lack of knowledge on the determinants of Residential Satisfaction (RS) concept. Results of most studies indicate that housing satisfaction is affected by an array of individual, housing and neighborhood attributes. Nonetheless it’s also important to take into account the effect of social interactions. RS has been an important factor for policy makers during the preparation of their guide line of housing construction for the variety of people. RS for policy makers means that the habitants and resedents needs have been met and that they are happy in their dwelling unit. Residential Satisfaction and its effective relationship with Quality of Life are of those concepts into consideration in recent decades. Not recognizing RS in designing projects leads to a severe problems. These problems includes projects do not satisfy the occupant’s needs, in terms of comfort, social, cultural and religious needs. Consequently, it influences the quality of life and affects the psychosocial aspects of the inhabitants. This study has aimed to investigate the residential satisfaction of Mehrshahr, which had once been consisted of low-rise single house units, settling high-income residents and in recent years has modified to a composite dense structure. So assessing changes occurred in this region is the main point of the study. To achieve this goal,after research several attributes in subjective and objective dimensions were evaluated, applying several regression analysis and a model attributed to Amerigo and Aragones in 1997. Previous models in community satisfaction have included many different categories of variables, but no model has yet incorporated all of them simultaneously. The data were collected through field inquiry and the results indicate low residential satisfaction(below average) in this region, which regarding their length of residents, with significant percentage dwelling less than 10 years, infer the lack of sense of place among individuals.

  Stomach cancer destroys the tissues of the digestive system. This cancer is one of the deadliest diseases. Endoscopic imaging is used to diagnose cancer. In endoscopy, the diagnosis of gastric cancer is difficult due to the similarity of the tissues, the low contrast of the image and the background. In order to overcome these problems, discrete wavelet transform has been used to detect stomach cancer. In the proposed method, there are data registration, data preprocessing, feature extraction, dimensionality reduction, and classification. The features are extracted with the help of discrete wavelet transform and then dimension reduction is done with the help of principal component analysis. The proposed approach was evaluated on datasets collected from five classes, including gastritis, ulcer, esophagitis , bleeding, and healthy. Jungle Tassafi has a value above 99% in all evaluation criteria, which represents the advantages of this category. The results of this research show that this method is accurate and reliable in diagnosis. Manuscript profile

       This study was carried out to determine the process of formation, development and topographic characteristics of different parts of stomach and extent of their rotation in sheep fetuses. For this purpose, 14 ovine fetuses at the age of 38,40,45,47,52,58,66, 75, 80,88,103,110,130 and 150 days of gestation were examined. The uteri of 50 pregnant ewes were collected from the abattoir and after determination of the age of the fetuses, they were fixed in 10% buffered formalin solution and following necropsy, the topography of stomach was studied. At 30-day of gestation, the omasum was seen opposite the reticulum and results indicated that its development takes place along the vertical axis. At 38 days rumen was the largest part of the stomach situated cranial to reticulum, while at 47 days of gestation, the size of rumen and reticulum was approximately equal. The enlarged rumen moves caudally and the reticulum moves forward from underneath the rumen at about 52 days of gestation. At 66 days, rumen was the largest chamber in comparison to other parts of the stomach and the reticulum was located completely in front of the other parts. The abomasum was massive at 103 days and it was the largest part of stomach at 110 days of gestation. The results indicated that at the beginning of the developmental process, the rumen is situated cranially and abomasum caudally. Gradually as the rumen enlarges it migrates dorsal and caudal to the abomasum. Finally, the reticulum moves forward underneath the rumen and forms the most cranial part of the stomach.

  Upper gastrointestinal tract contrast study commonly refers to administration of contrast media orally. Determination of normal gastric emptying time and small intestinal transit time are useful in detecting gastrointestinal motility disorders and partial obstructions of the pylorus or small intestine. This study was conducted to evaluate radiographic anatomy and function of stomach by using contrast media in the New Zealand White Rabbit. Ten clinically healthy adult rabbits were prepared and kept for two weeks prior to study. After twenty four hour fasting, plain lateral and ventrodorsal radiographs were obtained. Ten milliliter per kilogram body weight of Iohexol was administered orally to the rabbits. Lateral and ventrodorsal radiographs were taken at zero, 10, 20 and 30 minutes after administration of contrast media and then in 30 minutes intervals until stomach completely been cleaned. Early gastric emptying time was started at 7.35±4.15 minutes. Delay gastric emptying time was started at 418.00±97.23 minutes. Manuscript profile

  Bats play a special role in the earths ecosystem by eating harmful insects, helping in pollination of trees and producing precious fertilizer. Due to their ecologic and economic importance, and to get a better understanding of bats, the differencebetween histology of gastric tissue in two species of bats namedRhinopoma hardwickii and Rousettus aegyptiacusis studied. In this research five insectivorous bats and five flying fox were chosen from Jahrom in the province of Fars, tissues of their stomach were prepared, and sections were compared regarding presence or absence of perez, type of muscle cells, type of glands, type of gland secretions, types of cells, existence or lack of serous membrane, and presence or absence of pits were examined by light microscopy.The results showed that the stomach tissue in both species were similar to mammals and had 3 areas: cardia, body and pylorus; however, the lining mucosa and sub-mucosa in fruit-eating species were thicker and specific and had more collagen fiber than the insectivorous species. Based on the present study, in general, the stomach layers in flying fox species are thicker than that of Insectivorous bats; that is probably because of bigger stomach of flying fox comparing with the insectivorous species which is probably due to the greater size of the stomach in flying fox species which is due to the necessity of more time for digesting the cellulosic materials in flying fox species stomach.

  Today, microplastics are among the most important environmental pollutants that have attracted the attention of scientists. These plastic particles enter the food chain by being swallowed by animals and cause serious damage to humans and animals. The purpose of this research is to investigate the effect of polystyrene microplastics on the digestive system of mammals. The rats were divided into 3 groups of 6; the sham group received 200 microliters of distilled water once a day for 30 days. The first group received 200 microliters of nano-styrene once a day with a dose of 0.1mg⁄kg for 30 days. The second group received 200 microliters of nano-styrene once a day. He received a dose of 0.5 mg⁄kg for 30 days. The day after the last gavage, the animal was anesthetized with chloroform, and the intestinal and stomach samples were stained for histological examination in 10% buffered formalin solution with hematoxylin-eosin staining method. TUKEY test was used for statistical analysis and comparison between groups. All the calculations were done using Prism software and the significance level of the tests P was considered less than 0.05. The statistical findings show a decrease in the diameter of the submucosa, the number of lining cells, and the number of epithelial cells in the experimental group 2 compared to the control group. The height of the intestinal villi and The stomach showed an increase in experimental group 2 compared to the sham group. The results of this study show that the effects of nano-styrene depend on the concentration and as the concentration increases, it will leave more destructive effects on the intestines and stomach.

  Background & Purpose: Bezoar is an intraluminal mass in the gastrointestinal tract that is formed by the accumulation of indigestible materials. Trichobezoar is the accumulation of hair and fur that passes through the esophagus and becomes a foreign body in the stomach or intestines. The pyloric region is a frequent site of obstruction which can block the gastric outlet. The notability of diet in rabbits is so high that poor nutrition with low fiber, protein, carbohydrates and high fat result in bloating and accumulation. Materials & Methods: In the studied animal, clinical signs, graphs and blood analysis revealed an accumulation of gas in the stomach and intestines and an aggregation of foreign body. The Exploratory laparotomy technique was approved to correct the complication. Results: After induction of anesthesia and a ventral midline incision, the furry and greasy masses were removed and the incision area was sutured. The animal began to gain weight after 14 days by correcting the diet and kept on living. Conclusion: It is recommended that to preparing starter feed due to a limited capacity for hydrolysis of several components at early ages, high amounts of digestible foods which are rich in fat and protein, with low fiber should be used to prevent disorders such as bloating and obstruction.
