Investigando o efeito destrutivo do terremoto em paisagens urbanas (estudo de caso: Ahar City)

This research has been conducted to determine the vulnerability of Ahar city spaces due to geographical location and other influential conditions. Using the results of previous researches and presenting combinational components and the modern indexes using the AHP model, this issue has been addressed and, finally, the output of data has been provided. In general, the results of the vulnerability analysis of the spaces of Ahar town indicate that most of the constructed parts of the city are in the moderate vulnerability area; marginal settlements are in the area of high vulnerability and central and historical parts are classified in the area of highly vulnerable zones. However, in the zoning of the whole city’s vulnerability, which includes built and arid spaces, the city is placed in the very low vulnerable classification. Accordingly, preventing the unauthorized separation and construction in marginal neighborhoods, the construction of neighborhood parks, the construction and completion of the main road network, the preparing restoration and renovation projects of worn-out and marginal textures, prevention the unauthorized separation outside the legal boundaries of the city, the transformation of abandoned cemeteries into public spaces such as the green space and cultural spaces, wall-laying and channeling of the rivers and river sides and dredging and updating them, are priorities of planning and implementation to rehabilitate the city of Ahar in response to the earthquake.Esta pesquisa foi realizada para determinar a vulnerabilidade dos espaços da cidade de Ahar devido à localização geográfica e outras condições influentes.

Em geral, os resultados da análise de vulnerabilidade dos espaços da cidade de Ahar indicam que a maioria das partes construídas da cidade está na área de vulnerabilidade moderada; assentamentos marginais estão na área de alta vulnerabilidade e partes centrais e históricas são classificadas na área de zonas altamente vulneráveis. No entanto, no zoneamento da vulnerabilidade de toda a cidade, que inclui espaços construídos e áridos, a cidade é colocada na classificação muito baixa e vulnerável. Assim, impedir a separação e construção não autorizadas em bairros marginais, a construção de parques de bairro, a construção e conclusão da rede rodoviária principal, a preparação de projetos de restauração e renovação de texturas desgastadas e marginais, impedir a separação não autorizada fora dos limites legais da cidade, a transformação de cemitérios abandonados em espaços públicos como o espaço verde e espaços culturais, colocação de muro e canalização dos rios e fluviais e dragagem e sua atualização, são prioridades de planejamento e implantação para reabilitar a cidade de Ahar em resposta ao terremoto.Esta pesquisa foi realizada para determinar a vulnerabilidade dos espaços da cidade de Ahar devido à localização geográfica e outras condições influentes.

Investigating the Impact of Stock Price Index on Credit Risk of Banks Listed in the Stock Exchange Market

Purpose: Full employment has a mysterious meaning, full employment certainly does not mean employment of any member of the active population of the society who is of working age.one reason is that there are probably always people who find themselves unemployed due to various disabilities. Another reason is that at any time you can find workers who want to change jobs and remain unemployed during the job change period. Methodology: The method of descriptive correlation research was used and in terms of purpose, type of research It is applied and the library method is used to complete the literature and research background and the field data is collected through the archives and documents of the Central Bank website and the data of the Stock Exchange and Securities Organization to facilitate the analysis of data from Excel spreadsheet and regression method and Eviews statistical software are used to test research. Findings: The results show that the effect of stock index on variable risk and software use and comprehensive statistics of our research includes all banks and credit institutions listed on the stock exchange. Originality/Value: The available statistics show that the developed stock exchanges are located in developed countries and in these countries, more than anything, investment security is provided for the entry of domestic and foreign investors in the stock exchange. Market security is affected by various factors such as political, economic, and social and others. But in this study we intend to analyze macroeconomic variables

The Relationship Between Ankle-Brachial Index and Number of Involved Coronaries in Patients with Stable Angina

<p class="abstract"><strong>BACKGROUND:</strong> Atherosclerosis is the commonest cause of vascular disease which can involve peripheral and/or cardiac vessels. This study was conducted to evaluate the possible link between Ankle-Brachial Index (ABI) and coronary vessel involvement in patients with stable angina.</p> <p class="abstract"><strong>&nbsp;&nbsp; METHODS:</strong><strong> </strong>This cross-sectional study was conducted in 2008 on 120 individuals who were hospitalized in Chamran Heart Center and underwent coronary angiography. A questionnaire was completed to obtain demographic information, history of previous heart disease and smoking. Body height and weight, as blood pressure on hand and foot were measured. The patients underwent angiography and the extent of coronary involvement (&gt; 75%) was determined. After12-14-hour of fasting, blood sugar was obtained to measure total cholesterol, triglyceride, low-density lipoprotein cholesterol (LDL-C) and high-density lipoprotein cholesterol (HDL-C). The Ankle Brachial Pressure Index (ABI) was calculated as the ratio of the blood pressure in the ankles to the blood pressure in the arms. The data were analyzed by SPSS-15 using ANOVA, T-Student test, Spearman's rank correlation coefficient, and discriminant analysis.</p> <p class="abstract"><strong>&nbsp;&nbsp; RESULTS:</strong> Samples were 46 women (38.33%) and 74 men (61.67%) with a mean age of <br /> 55.50 &plusmn; 10.49. Mean and SD of ABI in men and women was 0.72 &plusmn; 0.20 and 0.80 &plusmn; 0.19 with no significant difference (p = 0.012). The correlation between ABI and extent of coronary involvement was 0.47 (p &lt; 0.0001). The group with lower ABI had the highest levels of coronary involvement (triple vessel, p &lt; 0.05).<strong>&nbsp;</strong></p> <p class="abstract"><strong>&nbsp;&nbsp; </strong><strong>CONCLUSION:</strong> ABI had a significant relationship with the degree of coronary involvement and a significant predictive value. Therefore ABI seems to be a reliable indicator of high coronary risk.</p> <p class="abstract">&nbsp;</p><table cellspacing="0" cellpadding="0" align="left"><tbody><tr><td width="35" height="12"><br /></td></tr> <tr><td><br /></td> <td>&nbsp;</td></tr></tbody></table><p class="abstract">&nbsp;</p> <br /> <p class="abstract"><strong>Keywords:</strong> Ankle to brachial index, Coronary involvement, Stable angina.</p> <p class="abstract">&nbsp;</p

The Predictive Factors of Recurrent Deep Vein Thrombosis

<p><strong>BACKGROUND:</strong> About 2-5% of people experience deep-vein thrombosis (DVT) during their lives. Death, disease recurrence, post-thrombotic syndrome, and excessive bleeding due to coagulant medications are among the most important DVT complications. Recent research found a high incidence of DVT recurrence after the first attack. Disease recurrence has a multifactorial pathogenesis and its probability is related with the number and severity of risk factors. The present study aimed to investigate DVT recurrence and the associated risk factors.</p> <p><strong>METHODS:</strong> This retrospective cross-sectional study evaluated all DVT patients hospitalized in Alzahra Hospital, Isfahan, Iran, during April 2000 to April 2011. The risk factors were obtained from patients' records including smoking, intravenous drug abuse, having a history of surgery in last four weeks, immobility, obesity, history of cardiac disease, and cancer. <strong>&nbsp;</strong></p> <p><strong>RESULTS:</strong> A total number of 2550 DVT patients were hospitalized in Alzahra Hospital during the study period. It was only possible to extract the data from 385 patient records. A history of DVT was reported in 48 individuals (12.5%). The comparison between the risk factors in patients with a first time DVT and those experiencing a recurrent DVT revealed significant differences solely in the prevalence of blood disorders and immobility. Applying stepwise regression indicated immobility (OR: 4.57; 95% CI: 1.26-16.57; P &lt; 0.021) and coagulopathy (OR: 0.33; 95% CI: 0.13-0.81; P &lt; 0.016) with DVT recurrence.</p> <p><strong>CONCLUSION: </strong>Based on our findings, DVT patients are suggested to be mobilized as soon as possible. In addition, they should be advised to increase their activity after discharge.</p> <p>&nbsp;</p> <strong>Keywords: </strong>Deep Vein Thrombosis, Immobility, Risk Facto

Contribution to the knowledge of Entomobryomorpha (Hexapoda: Collembola) from Northeastern Iran with new records and a key to the species

Soil-dwelling Entomobryomorphan Collembola from the Northeast of Iran were sampled for the first time as part of a biodiversity surveying study with the aim of improving ecosystem conservation. Materials were obtained by sampling in three different ecosystems including forest, rangeland and agricultural fields between 2018 and 2019. The specimens were cleared using either Nesbitt’s fluid or lactic acid and permanent microscopic slides were prepared using Hoyer’s medium. As the result of this study, twenty-nine species belonging to twenty-two genera and five families of the order Entomobryomorpha were identified. Among them, two genera and eight species are recorded for the first time from Iran. The new records are Desoria trispinata (MacGillivray, 1896), Drepanosira hussi Neuherz, 1976, Heteromurtrella sp., Orchesella flavescens (Bourlet, 1839), Willowsia bartkei Stach, 1965, Agrenia sp., and Isotomiella gracilimucronata Rusek, 1981. Micrographs of their important features and a key to the species are also provided. © 2022, Mehrafroz Mayvan et al
