The Deh-Chah metamorphic complex is situated approximately 265 km east of the town of Shiraz and 62 km east of the town of Nayriz, Fars province, in the south of Iran. The age of the metamorphic rocks is middle Paleozoic and the initial granite intrude into the micaschists and amphibolites and cause the garnet and tourmaline mineralization. There are In the massive outcrops of gneiss in north of Deh-Chah that are located in Sanandaj-Sirjan metamorphic zone. In this paper we conducted microscopic and macroscopic genesis and related mineralization were investigated. Microscopic studies indicate that main minerals are quartz, feldspar and biotite, which is evidence of the transformation of motion as Gneissosity, mylonitic texture in microcline and orthoclase become certified, also accessory minerals are sphene and zircone. \nThe results of chemical analysis and diagrams related geochemical ICP.MS indicate that Dehchah granite gneisses of which is formed in calc-alkaline volcanic arc (VAG). Also, the primary types of granite gneiss of Dehchah is magmatic type (I). In some cases garnet frequency is more than 35%, with regarding the 10% of economica, so the garnet frequency is important.

Stability of soil slope in geotechnical engineering is one of the most important issues and since the earthquake is an essential factor in stability of soil slopes, assessment and dynamic analysis of soil slopes is always important. The homogeneous earth dams which prevent penetration of water by geomembrane are very suitable to store water and other liquids. Some dams do not need complex engineering calculations, their cost is low and they are not difficult to build. To ensure the geotechnical safety of dam, slopes embankments must be designed and built carefully. In this paper a number nomogram has been prepared in accordance with the geometry of the earth dams to calculate safety factor. The finite element method was used to calculate stability. The finite element method requires careful study of the mechanical properties of materials and calculating the stress and body displacement. ANSYS software modeling was used to model and examine the stability of the earth dam . To ensure the accuracy of the modeling and validation of the results, first the natural frequency of the system was studied using modal analysis and was compared with the results obtained from analytical relations. The results showed that the main contribution in improving the behavior of a reinforced earth slope is increasing the horizontal stiffness of the soil mass and the reinforcement significantly reduced vertical, horizontal, and shear strains. Also reinforcement reduced deformation of the slope outside surface. The amount of this deformation reduction depends on reinforcement spacing, slope angle, hardness of the soil and reinforcement, and foundation hardness. Generally use of reinforcements enhances the stability, protects the slope against coastal erosion, creates internal drainage in the dam and results in better performance. By increasing the height, the embankment reinforcement will consume the greater percentage of their resistance potential

Mycobacterium avium subsp. paratuberculosis (MAP) causes Johne’s disease, chronic progressive enteritis in ruminants. The organism has also been isolated from primates, including humans. The disease is economically important in the cattle industry but its control is hampered by the lack of accurate rapid diagnostic tests. Range of diagnostic tests is available, but all have inborn limitations. In the present study, a loop-mediated isothermal amplification (LAMP) assay for the rapid and simple detection of Mycobacterium avium subsp. paratuberculosis (MAP) was developed. Six primers were specially designed for recognizing eight distinct sequences of insertion sequence 900 (IS900). Optimization of LAMP reaction was performed. Time and temperature conditions for amplification of MAP were optimized as 60 min at 63°C. LAMP produces extremely large amounts of amplified products and enables simple detection methods such as visual judgment by the turbidity or fluorescence of the reaction mixture, which is kept in the reaction tube. The visual detection eliminates the need for time-consuming electrophoresis and costly specialized equipment. The performance of LAMP was compared to that of a highly sensitive Nested PCR. The sensitivity of LAMP assay for detection of MAP was 4 fg and the specificity was 100%. The sensitivity was 1000 times greater than the Nested-PCR. Furthermore, the LAMP assay described in this report is simple to use, inexpensive, highly sensitive, and particularly well suited for the early diagnosis of MAP in less well equipped laboratories and in rural settings where resources are limited.

In this article, the generalized inverted Rayleigh distribution (GIRD) is presented. Some of the mathematical properties of this distribution are studied. We derive the quantile function, shape of hazard rate function, moments, mode, harmonic mean, skewness and kurtosis. Also, order statistics, mean deviations about mean and median are obtained. Other important properties including entropy (Shannon and Rényi) which are measures of the uncertainty in this distribution are also presented.

La teoría de juegos es una herramienta que permite examinar el comportamiento estratégico de los participantes, a partir de sus tres características básicas: Reglas, Estrategias y recompensas o resultados, los integrantes del juego actúan precisamente motivados por la maximización de sus utilidades, y supone que los adversarios son racionales, se toma en cuenta el comportamiento esperado del otro, se considera el reconocimiento mutuo de la interdependencia. Su aplicación en el mundo real se manifiesta en situaciones en las que, al igual que en los juegos, el resultado de una acción depende de la decisión o conjunto de decisiones que cada participante toma en el transcurso de un determinado lapso. El objetivo del presente ensayo es analizar el enfoque del estándar mínimo seguro como principios operativos que soporta algunas decisiones institucionales y estatales relacionadas con el desarrollo sostenible a través del modelo del dilema del prisionero y el modelo Halcón o Paloma de la teoría de juegos, estableciendo en ambos casos la condición de equilibrio de John Nash desarrollado en la misma teoría, realizando un análisis económico en cuanto a la incertidumbre que involucra la destrucción irreversible de recursos ambientales no cuantificables en el presente pero si se evidencian su impacto en el futuro

This paper presents an overview of research design and sampling as a sine qua non for conducting researches in the area of social and management sciences (SMS). Ineffective research design and sampling are usually the bane of successful and logical conclusion of researches with valid useful findings and inferences for decision making. The paper was motivated by the desire to provide a study and/or teaching/training materials on research design and sampling procedures in the 21st century that will be easily understood and applied by researchers, including undergraduate and postgraduate students, trainers, trainees, teachers and a wide non-specialist audience. Through intuitive and qualitative reasoning, the paper explores the conceptual, theoretical and empirical technical issues on the requirements, classification, types, methods and processes of research design and sampling. Data collected from 98 research experts and analyzed with one-way ANOVA at 5% level of significance show that researches before and during the 21st century are the same. Also SMS researches in the 21st century are usually Information and Communication Technology (ICT) driven. Technological advances need to be incorporated in the research process in order to facilitate and expedite conducting researches for the realization of objective functions. Review of research design and sampling procedure prior to implementation, exploring and application of latest computer software and adherence to specifications are advocated for timely, quality and cost effective completion of researches in the 21st century.
