Abstract: 

Shotori Mountains located in east of Iran are important from geologic, geomorphologic and physical morphologic perspectives. These mountains formed by Naiband flat consist of geologic formation from Denovian to lower Kertacae, which mostly include lime stone and dolomite.Shotori Mountains result from coming up drifting on the Tabas plate through Austrian and Laramian orogenesis. This drift leads to asymmetric eastern and western hillsides, therefore hydrographic drainage lean to western hillside and rainfall flews to the Tabas plate which causes agricultural development in Tabas.Remained climate is observed everywhere in vallies and outside of the mountains (e.g. alluvial trases, alluvial cones, etc). Interesting landscapes observed make Shotori Mountains as a “geo top” which can attract tourists and cause economic development.

Abstract: 

Kurdish, a northwestern Iranian language (Dabir Moghaddam, 2012, p. 598), holds a unique position among Iranian languages. Some scholars (McCarus 2009, p. 587) argue that Kurdish does not belong to a single, uniform group within Iranian languages, while they agree that this language occupies an intermediate position between the western, northern, and southern Iranian dialects. As such, the term “Kurdish” can be seen as a cover term for closely related language varieties in the western group of Iranian languages. Three main dialects of Kurdish are Northern Kurdish (Kurmanji), Central Kurdish (Sorani), and Southern Kurdish (Kalhori) (Blau, 1989, pp. 542-544 and McCarus, 2009, p. 587; Dabir Moghaddam, 2012, p. 601).The present study investigates whether compensatory lengthening exists in the Kurdish language. If compensatory lengthening does occure, the deletion of a mora-bearing consonant in the coda position would result in a stray mora. This stray mora would then reconnect to its preceding vowel in languages where the coda consonant triggers Compensatory Lengthening (CL) and the vowel is the target. In Kurdish, there are tautosyllabic clusters with CL, such as /ʃahɾ/: [ʃɑɾ] ‘city’ and /taʕm/: [tɑm] ‘taste’, as well as heterosyllabic clusters with CL, like /lah.ʤa/:[lɑ.ʤa] ‘accent’ and /maʕ.nɑ/: [mɑ.nɑ] ‘meaning’. The primary focus of this study is to determine whether these two consonants are moraic in Kurdish and to identify the threshold for moraicity in this language. It is also important to note that these words are not native, so they can be seen as a nativization process adapted by native speakers of Kurdish.CL has been extensively studied in many languages, including Persian and Kurdish. In Persian, this process has been examined from various perspectives; Darzi (1993) and Kord Zafaranlu Kambuziya (2000) conducted general investigations; Bijankhan (2000) and Sadeghi (2007; 2019) adopted a perceptual viewpoint, while Shademan (2005) approached it phonetically, and Safaie-Qalati (2013) used a cognitive approach. Among these works, only Mahdavi et al. (2019) investigated this process within the framework of Stratal OT (STOT).In terms of Moraic theory, compensatory lengthening was studied by Alinezhad & Zahedi (2009) in Sorani Kurdish, Badakhshan & Zamani (2015) in Kalhori Kurdish, Sobati (2018) in Ilami Kurdish and Ahmadi Varmazani & Fattahi (2019) in Kermanshahi Farsi.

Abstract: 

Introduction: Infection by M. tuberculosis can be demonstrated by tuberculin testing. On sequential PPD some person show a marked increase in the size of their skin reactions which may not be due to recent or past tuberculous infection. This phenomenon (booster effect) can occur as soon as a week after the initial test and persist for as long as a year.Methods and Materials: The purpose of this research is studying the size of induration following repeated PPD tests (booster effect) that studied in children who came to our clinic or imbedded in pediatric unit and the group of student in grades 4 and 5 at elementary school (totally 80 cases) for one year.Results: Increase of induration in 25% of all (20 cases) was 5 mm or more and in 75% of all (60 cases) was less than 5 mm and between these two groups, differences was meaning full (P<0.05). The increase of induration in 12.5% was 7 mm or more.Conclusion: Because there is not shown definite increase of induration (more than 5mm) on sequential PPD in children, we must to consider to new infection.

Abstract: 

BACKGROUND & OBJECTIVE: Ophthalmological complications in transplanted patients are often due to underlying disorders or drug use and consists anterior segment and posterior segment complications that central serous chorioretinopathy among the posterior complications is related to high dose steroid, stress or cyclosporine and usually has a good outcome. In this paper, we report a case with CSCR as an ophthalmologic complication of renal transplantation.CASE: A 36-year-old man hospitalized for treatment of rejection, suffered from severe visual loss in both eyes that after exam and fluorescin angiography CSCR (due to high dose steroid use for rejection) was diagnosed. With tapering of the drug and after about 3 months, visual acuity became normal.CONCLUSION: Visual acuity changes must be followed carefully in all transplanted patients but CSCR usually has a good prognosis and after tapering of dose steroid, improvementmay be seen.

Abstract: 

The present study was conducted by examining the views of relevant experts and their exposure to child labor in Shiraz. Data were obtained through in-depth interviews and analyzed based on grounded theory. Ten axial categories and one core category were extracted from the coding process. The core category was developed under the title of "institutional passivity and sectoralism". The results of the research showed that the causal conditions such as incompatibility and institutional and managerial confusion, diversity of perspectives to the phenomenon of child labor and non-governmental organizations and indifference towards child labor has caused the emergence of this phenomenon. Intervening conditions include: negative representation and conflicting media activities, Inhibition of some domestic and international rules and laws and child labor of nationals and the problem of identification and identity. This central phenomenon is located in special conditions and contexts due to family pressure and starting the work process in childhood, child labor as an income generating industry, child labor as a source of financial support for the family and the unique opportunity for working children, and Shiraz's oppurtunities for immigrants. The type of encounter with working children in Shiraz has caused numerous consequences that can be seen Unreasonable increase of child labor of nationals, Failure to contain and control the problem of working children, lack of proper organization and social support of working children, Anonymity of working children and persuasion and encouragement of nationals to immigrate to Shiraz.

Abstract: 

در این مقاله، بهینه سازی خواص مکانیکی آلومینا با استفاده از افزودنی ها مورد بررسی قرار گرفت. آزمایش ها به روش Central Composite و با انتخاب سه متغیر مستقل، دمای پخت، نیروی فشردن و درصد افزودنی (CaO + SiO2) انجام گرفت. دو عامل چگالی و استحکام خمشی نمونه ها اندازه گیری شد و ترکیب بهینه. مطابق نتایج به دست آمده در مورد چگالی، با توجه به اثر تک تک این عوامل، دما و نیروی فشردن به ترتیب بیشترین تاثیر را بر افزایش چگالی دارند. با افزایش مقدار افزودنی به بالاترین حد، مقدار چگالی کمی افت می کند. به نظر می رسد بیشترین مقدار چگالی در وضعیت صفر یعنی مقدار افزودنی در حدود 0.125 درصد مولی به دست می آید. در مورد استحکام خمشی مشاهده که دمای پخت بیشترین تاثیر را بر افزایش استحکام دارد، به طوری که با این عامل به تنهایی (دو عامل دیگر در پایینترین حد یعنی وضعیت 1- باشند) می توان مقدار استحکام را به حدود 70 درصد استحکام نهایی رسانید. پس از آن، نیروی فشردن بیشترین تاثیر و عامل مقدار افزودنی کمترین تاثیر را بر روی افزایش استحکام دارد. نتایج نشان داد که بهترین ترکیب دارای بالاترین دمای پخت (1650oC) بالاترین نیروی فشردن (130MPa) و بالاترین مقدار افزودنی (0.25mol%) است.

Abstract: 

Purpose: To present the second case of photopigment bleaching phenomenon in fluorescein angiography (FA) and the first case of this phenomenon due to impending central retinal vein occlusion (CRVO). Case Report: A 32-year-old healthy female noticed blurred vision in her right eye one day before presentation. Despite the 20/20 visual acuity at presentation, mild increased retinal vascular tortuosity and unilateral photopigment bleaching phenomenon in FA was observed in the right eye. Three weeks later, she developed a complete CRVO with visual acuity reduction to 20/40 that responded well to the intravitreal injection of aflibercept. Conclusion: Impending CRVO can cause unilateral photopigment bleaching phenomenon in FA that may be due to retinal ischemia.

Abstract: 

در آوریل سال 2005 در طی بازدید و کارگاه آموزشی اکتشاف کانسارهای پورفیری در شیلی مرکزی (که در کشور شیلی برگزار گردید)، از چهار معدن مهم (World Class) پورفیری شیلی، بازدید گردید. این چهار معدن در واقع متشکل از سه سیستم پورفیری می باشند که شامل معادن ال تنینت (El-Teniente)، ریوبلانکو – لوس برونسز (Rio Blanco-Los Bronces) و لوس پلامبراس (Los Pelambres) می باشند. این کانسارها در غنی ترین ایالت مس دار دنیا در سلسه کوه های آند قرار دارند. این کمربند به تنهایی دارای ذخیره ای بالغ بر 490 میلیون تن (با احتساب تولیدات قبلی) مس خالص می باشد که در 63 کانسار پورفیری شناخته شده وجود دارد.بطور کلی کانسارهای پورفیری آند در 5 کمربند متالوژنی از مرکز شیلی تا جنوب پرو و شمال غرب آرژانتین تشکیل گردیده اند که به لحاظ زمانی متعلق به کرتامه فوقانی و پلیوسن می باشند. کانسارهای شیلی مرکزی عمدتا بسیار جوان می باشند و متعلق به اواخر میوسن و پلیوسن می باشند.با توجه به اینکه یکی از کمربندهای مهم کانی سازی نوع پروفیری در ایران قرار دارد بر آن شدیم تا مقایسه ای بین معادن و کانسارهای پروفیری ایران و شیلی مرکزی انجام دهیم. در ایران در حدود 53 سیستم پورفیری بزرگ و کوچک شناخته شده است که در این میان تنها سرچشمه به عنوان بزرگترین کانسار از این نوع در ایران در مقیاس جهان (World Class) قابل توجه است. بهر حال مقایسه می تواند از بسیاری جهات بویژه از نظر اکتشاف مفید واقع گردد.

Abstract: 

A B S T R A C TToday, all officials involved with the challenges of city sustainability have accepted the idea of a smarter city, using more technologies, creating better living conditions and protecting the environment for a better quality of life. The central part of the metropolis of Tabriz is based on Region 8 and part of Region 10, a historical-cultural area with an area of 286 hectares and a population of about 40 thousand people in 8 neighbourhoods. This research was compiled to evaluate and explain the regeneration of the central part of Tabriz city with the approach of smart growth and in line with the sustainable development of problematic neighbourhoods in the 8th district of Tabriz metropolis. The present review is methodologically practical, to describe and analyze the goals of regeneration based on library studies. The statistical population of the research includes experts and people living in the central context. In the first part, the Delphi method was used by asking experts. In the second part, the structural equation method of SPSS and AMOS software is used. According to the results of using the scales of design, pedestrian-oriented, intergenerational justice in the actual situation and 3 indicators of management and productivity, stable and value-creating jobs are in the potential situation. Also, two environmental indicators with the most direct and indirect effects and a cultural index have been decisive in the regeneration with the smart growth approach in the central part of Tabriz city. Therefore, in the regeneration of the central part, the studied indicators should be used simultaneously and integrated into the reconstruction projects of the central fabric of the city to lead to smart sustainabilityExtended AbstractIntroductionSmart growth is considered a lever for revitalizing neighborhoods and urban centers. In a general scenario of smart growth, knowing the time and resources of investment provides a new and sustainable life in the city center and worn-out and old textures. Moreover, finally, it will improve the quality of urban neighborhoods, especially worn-out ones, and revive them. Tabriz metropolis, one of the most important and largest cities in the country, with a long history of settlement, especially the central and old texture, due to developments in information and communication technology, extensive environmental, social, and economic changes in terms of time requirements, the traditional texture of roads, Deterioration of residential units, lack of equipment, infrastructure and urban services and environmental problems have caused the failure and physically turned into inefficient and problematic textures. Urban planning and development science must adopt a new decision and approach to face the existing and complex issues of worn-out texture. The main problem of the research is to evaluate and explain the regeneration of the central texture and strengthen them in line with the sustainable development of the problematic neighborhoods of Tabriz metropolis according to the solutions and principles of smart urban growth. Therefore, the main goal of this research is to answer the following question:- What are the effective indicators and components in the regeneration of the central texture of Tabriz metropolis with a smart growth approach? MethodologyThis research is applied and fundamental in terms of purpose and descriptive-analytical. The collection methods are based on documentary and library studies, surveys, and interviews. In the first part, qualitative data was prepared with an open questionnaire and through interviews, as well as the review of documents and quantitative data used in this research numerically and through the weighting of Delphi questionnaires based on the consensus index model to determine importance, certainty, and priority. The panel members were 19 people (including 5 university faculty members, 7 field research experts, 4 executive experts, and 3 graduate students) selected based on the non-probability (targeted) method. In the second part, Cronbach's alpha method was exerted to measure the reliability of the questions, which was obtained as 0.89. In order to evaluate the validity of the questionnaire, the Lawshe method was exploited. The statistical population of the second part includes District 8 of Tabriz, which is the central texture of the city and is equal to 34,231 people. According to Cochran's formula, the sample size was equal to 379 people. Results and discussionIn the next step, path analysis was performed using AMOS 23 software to compare the integrated model with the hypotheses. The results of the path analysis, while verifying the structures, show that the value of the index of the critical ratio to the degree of freedom (CMIN/DF) is equal to 4.01, which is an optimal value for the model fit. Also, the goodness of fit index (GFI) is 0.952, which indicates the acceptability of this amount for the optimal fit of the model. The value of the root means the square error of estimation (RMSEA) is 0.065, which is acceptable because it is smaller than 0.08 and indicates the confirmation of the research model. Also, the Tucker-Lewis index (TLI) is 0.917, the comparative fit index (CFI) is 0.92, and the normalized parsimonious fit index (PNFI) is 0.882, which all indicate that the fit and verification of the research model are desirable.Therefore, none of the objects are removed and remain in the model. Therefore, it is confirmed that the factor structure of regeneration indicators with the smart growth approach has reliability and construct validity. Also, the second-order factor analysis shows that the factor loadings of all regeneration indicators with the smart growth approach are greater than 0.4 and are significant at the 95% probability level. According to the results, the environmental dimension with a factor loading of 0.94 has the most significant effect on urban regeneration with the smart growth approach in the central texture of Tabriz city. After that, quality of life with a factor loading of 0.92, social dimension with a factor loading of 0.88, economic dimension with a factor loading of 0.83, physical dimension with a factor loading of 0.81, transportation dimension with a factor loading of 0.74 and cultural dimension in order with a factor loading of 0.72, are in the following ranks.According to the final structural model results, the environmental index has the highest value, with a direct effect of 0.594 and an indirect effect of 0.275. Moreover, after that, respectively, the quality of life index with a direct effect of 0.513 and an indirect effect of 0.236, a social index with a direct effect of 0.476 and an indirect effect of 0.217, an economic index with a direct effect of 0.451 and an indirect effect of 0.222, Physical with the direct effect of 0.435 and indirect effect of 0.205, mobility index with the direct effect of 0.373 and indirect effect of 0.182 and cultural index with the effect of direct values of 0.295 and indirect effect of 0.153 are influential in regeneration with smart growth approach in the central part of Tabriz city. ConclusionIn this research, seven main indicators related to the subject were investigated. The results showed that the environmental index with the most significant direct and indirect effect is the focus of the evaluation. After that, dimensions and indicators of quality of life, social index, economic index, physical index, mobility index, and cultural index have been influential. According to the results, the urban environment index was analyzed as the most important factor at a high level, and this means that for urban regeneration with a smart growth approach, improving the environmental and physical conditions in the worn-out and central texture of Tabriz city in the current situation is a priority. It is first. This is the most well-known part of regeneration with a smart growth approach. The analysis results show that this is not the case only in the case of transportation infrastructure. However, more comprehensive urban infrastructure such as the urban landscape, open spaces, green and parks, etc. are also crucial in improving the physical conditions of the infrastructure. Also, this study's results show that the economic sector's importance is as important as improving the physical conditions of the infrastructure. In addition, in the worn-out texture of District 8 of Tabriz city, the sociocultural sector is essential, and the revival of historical and cultural resources is considered one of the urban regeneration options. Funding There is no funding support. Authors’ Contribution All of the authors approved the content of the manuscript and agreed on all aspects of the work.  Conflict of Interest Authors declared no conflict of interest. AcknowledgmentsWe are grateful to all the scientific.
