Panj-Kuh granitoid intrusion with an area of 15 Km2 is intruded into the Eocene volcano-sedimentary sequence, in south-east of Damghan city. Syenite is the main composition of the pluton. It has converted to monzonite wherever subjected to sodic-calcic alteration. The presence of albite-scapolite veins (from mm to some hundred meters in width) are the main evidences of the Na-Ca alteration in the mentioned pluton. Present study investigates the result of magnetic fabric in the Panj-Kuh pluton and defines the emplacement mechanism according to the lineation and foliation patterns and microstructural observations. The pluton belongs to the ferromagnetic granites due to high mean bulk magnetic susceptibility (Km>400mSI) and presence of magnetite. The highest anisotropy values were observed in the regions with high deformation. High plunging lineation and foliations associated with negative value of shape parameter show the magma feeder zones. According to the present study, it seems that the pluton has two different types of fabric patterns. The first pattern belongs to the magmatic liniation and foliation that are arranged parallel to the long axis of the pluton with NE-SW trend. The second fabric is related to the regions that were subjected to Na-Ca alteration and cross cutting the first pattern as three parallel corridors. This fact is confirmed by magmatic to low temperature solid state microstructures as well. Compiling all data implies that the mentioned pluton was emplaced in a sinistral shear zone.

The Challu granitoidic pluton composes of two monzodiorite and quart diorite units, injected into the Eocene volcanic rocks in south of Damghan. Emplacement mechanism of this pluton has been investigated by the anisotropy of magnetite susceptibility method. The measured mean value of bulk susceptibility (Km in mSI) in fresh quart zdiorites and monzonites are 31608 and 33726, respectively and then the pluton belongs to the ferromagnetite granites. In this granitoidic body, magnetite is the main carrier of magnetic susceptibility and biotite and pyroxene are the other accessory factors of magnetite nature. The field observation along with petrographical and magnetic fabric investigations reveal that the mentioned pluton emplaced at two stages with two different mechanisms. Monzodioritic unit with dominant porphyroidic texture and NS lineation trend and foliation strike parallel to the margin of the pluton emplaced along tensional gash of one dextral shear zone. Quartz dioritic unit at the same time or a time after monzodiorite emplaced as dyke. The magnetic fabric pattern, oblate ellipsoid shape as well as predominance of trachytoidic texture in this unit correspond with the inverse fabric dyking pattern and the orientation of plagioclase show magma flow. The magnetic susceptibility has been decreased in the stations that subjected to the hydrothermal alteration either by reduction of size of magnetite crystals or conversion of magnetite to hematite. The microstructures in the pluton are mainly magmatic and show high melt fraction to crystal during the emplacement or absence of tectonic stress after full crystallization.

Background and Aims: Disc displacement is the most common temporomandibular joint disorder and magnetic resonance imaging (MRI) is the gold standard in its diagnosis. This disorder can lead to changes in signal intensity of magnetic resonance (MR). The purpose of this study was evaluation of correlation between relative signal intensity of MR images of retrodiscal tissue, superior and inferior head of lateral ptrygoid muscle with type of anterior disk displacement and condylar head flattening in patients with temporomandibular disorder (TMD).Materials and Methods: In this retrospective study, 31 MR images of patients who had anterior disc displacement were evaluated. After relative signal intensity measurement for retrodiscal tissue, superior and inferior head of lateral ptrygoid muscle, the correlation between relative signal intensity and type of anterior disc displacement was evaluated with repeated measure ANOVA test. In each of these 3 areas, t-test was used to compare the groups with and without condylar head flattening.Results: The correlation between relative signal intensity of MR images and type of anterior disc displacement in retrodiscal tissue, superior and inferior head of lateral ptrygoid muscle was not significant. There was also no statistically significant correlation between relative signal intensity of MR images and flattening of condylar head in retrodiscal tissue, superior and inferior head of lateral ptrygoid muscle (P>0.05).Conclusion: According to findings of this study, relative signal intensity of MR images in retrodiscal tissue, superior and inferior head of ptrygoid muscle is not a good predictor for type of anterior disc displacement and flattening of condylar head. It seems that this cannot be used as a diagnostic marker for TMD progression.

The aim of this study is to investigate the optimum replacement of glass fabric with carbon fabric in epoxy matrix composites, focusing on achieving comparable mechanical properties while reducing manufacturing costs. The glass and carbon fabric-reinforced epoxy matrix hybrid composites are prepared with varying hybrid ratios of reinforcements (ratio of carbon fabric to total fabric) using the vacuum pump-assist hand lay-up technique. The composite samples are made in the shape of a plate. To analyze the tensile and flexural strengths of the fabricated composite samples, they are cut into corresponding dimensions as per ASTM standards. The effect of varying sequences of laminas and numbers of glass fabric and carbon fabric laminas on the mechanical properties of the composite is studied and compared, respectively. The improvements of 53.82% and 98.67% in the tensile strength and flexural strength, respectively, are noticed with an increment of the hybrid ratio from 0 to 1. The obtained results of the composites with various hybrid ratios can be used to select an optimal flexural strength as well as tensile strength in relation to a specific application and cost.

Cretaceous mafic dykes in the Moyar Shear Zone (MSZ) area, north Kerala, India, provide signatures to probe into the nature of their source and thereby the evolution of the Mesozoic lithospheric mantle beneath the South Indian Granulite Terrain (SIGT). Bulk of the dykes in northern parts of Kerala is broadly in spatial association with the shear system. Mafic dykes striking NE-SW, NWSE, NNW-SSE and ENE-WSW are widespread in the MSZ and surrounding areas. Width of these dykes varies from 30cm to 5m in general, while dykes wider than 10m also occur. These mafic dykes are olivine/quartz normative tholeiites showing strong correlation to N-Type MORB and within plate basalt affinity. Anisotropy of Magnetic Susceptibility (AMS) data imply normal magnetic fabrics nearly parallel to dyke trends, but with highly variable plunge of magnetic lineation. The compositions of the least altered and least metamorphosed dykes help to define the properties of their mantle source region, as well as the nature of the crust through which the magma traveled. The present contribution on the mafic dyke swarms in Moyar Shear Zone (MSZ) provides new interpretations on the temporal relations of magmatism and tectono-metamorphic evolution of the south Indian high grade terrain.

Themain purpose of this research is to analyze status of resilience indicesin the worn out and old fabricof Farujcity. Inthis regard, 32 indicators in four dimensions of physical-environmental, social, economic and institutional-managerial were selected based on theoretical studies of the research. In the next step, a questionnairebased on these indicators was designed and distributed among the residents of the study area. A total of 380 households participated in completion of questionnaires. Then, the collected data were entered into SPSS and analyzed by single sample t-test. Four dimensions of resilience were compared with each other and based on average scores. The results indicated that resilience in the institutional-management dimension with the average score of 2. 70 is ranked first. Thesecond rank of resilience was for the physical-environmental dimension with a mean score of 2. 47. Finally, social and economic dimensions were ranked third and fourth, respectively. Inanother section of the study, the importance coefficient of each indicator was estimated based on expertschr('39') opinions. Then, the results were integrated and indicators with higher priorities were identified. In this method, we are looking for indicators with a low average score but a high coefficient of importance. Based on the analysis, we found nine indicators with these characteristics, of which we can refer to indicators such as access to temporary accommodation, awarenessabout the occurrence of natural and human disasters in the neighborhood, the level of awareness about reactions, how to behave appropriately during the crisis, job security, financial strength of residentsto participate in resolving the crisis, and the extent to which the insurance organizations support the residents.

This study focuses on the tensile modulus and Poisson’s ratio variations of woven fabric in nonlinear region of load-extension curve. This region of the curve can play as a control approach on the secondary modulus/primary modulus ratio. For this purpose, the fabric modulus and Poisson’s ratio were determined for three different weave structures (plain, 1/3 twill, and 1/7 twill) in the warp and weft directions. The experimental results were analysed statistically to obtain the primary and secondary linear regions and also the nonlinear region of fabrics moduli. The analysis explain that the geometry of fabric structures such as the float and diagonal parts of yarn and also the yarn crimp in both warp and weft yarns have important role on the modulus and Poisson’s ratio of fabrics in the nonlinear region. It was found that the greatest range of the nonlinear region in the warp direction is for plain then, 1/3 and 1/7 twill weaves, respectively, by reason of the increase of diagonal part of yarn and the decrease of float part of yarn in fabric structures, simultaneously. But, due to the buckling of the float part of yarn in the weft direction, the 1/7 twill weave has the greatest range of the nonlinear region and the plain weave has the least one.

Flexible electronic printing devices have drawn significant attention due to the economic approach. Cotton fabric’s porosity and high surface roughness avoid electrically conductive printed patterns on the fabrics. In this study, the cotton fabric was pretreated with carboxylated styrene-butadiene latex (XSBL) with the pad-dry-cure process for in situ solution deposition of silver free particles inkjet ink. The pretreating process did not have an adverse effect on thermal behavior and colorimetric properties and improved the fabric’s crease recovery angle and hydrophobicity. The pretreated and untreated fabrics were printed through the HP Deskjet inkjet printer with one, five, and ten printing layers of formulated water-based silver free-particles ink for comparison. XRD analysis illustrated the crystal structure of silver nanoparticles on the printed pretreated cotton fabric. FE-SEM and EDS analysis indicated that the presence of silver nanoparticles increased by increasing the number of printing runs. Repetition printing sequences increased average particle size, growing grain size (52 nm to 90 nm). It was determined that the presence of XSBL on the fabric surface provides a suitable structure, with resistance (25 ohms) and antibacterial activity against gram-positive and gram-negative bacteria for use in multi-purpose inkjet printing cotton fabric. The printed pretreated fabrics exhibited appropriate washing fastness properties due to the cross-linked structure between free carboxylic groups of XSBL resin and hydroxyl groups of cellulose. It is the first time using an economical polymer layer on cotton fabrics to provide robust, flexible electronic inkjet printed fabric with great potential for commercial mass production.

In the last decade, a significant progress has been made in the wearable medical devices. Scientists are extensively involved in the design of the flexible instruments equipped with garments to fulfill the daily needs and requirements. The fulfillment of this demand particularly needs a conductive fabric substrate with a high level of homogeneity, and the lowest barrier against electrical current. In this study, textile based ECG electrode was prepared by screen printing of activator followed by electro less plating of copper particles. The data acquisition showed the best outcome with pH=8.5 and the plating temperature of 70 ˚C. The electrical resistance showed a range around 0.08 W/sq, which sounds quite proper for ECG signal acquisition since the potential difference according to heart activity on skin surface is in milivolt range. We tested the cardiac signal with a reference electrode of Electroshock monitoring system and the results revealed a very high quality receiving signal. Employing of these types of sensors in textile surface due to their flexibility can bring the users more freedom of action.
