Abstract

This paper analyzes the Magnetohydrodynamic unsteady convective flow of a viscous incompressible electrically conducting fluid past a vertical porous plate through a porous medium in presence of time dependent permeability, oscillatory suction and heat source. Employing perturbation technique, the solutions for velocity and temperature field are obtained. The effects of the pertinent parameters on velocity and temperature distribution of the flow field are studied analytically and discussed with the aid of figures for Grashof number, G_r > 0 corresponding to cooling of the plate. It is of interest to note that a growing magnetic parameter decelerates the velocity of the flow field at all points due to the action of Lorentz force on the flow field and an increase in heat source parameter leads to enhance the velocity of the flow field at all points. The effect of growing Grashof number for heat transfer/permeability parameter is to accelerate the velocity of the flow field in presence of heat sink while the effect reverses in presence of heat source, while the effect of increasing Prandtl number is to diminish the temperature of the flow field at all points.

Abstract

Odisha occupies 480 km of seacoast in eastern part of India where fish processing industries have been established. About 60,000 people depend upon the fish processing industries where they use small sharp knife and their fingers come in contact with different sharp body parts of fishes. Different activities like peeling, head and tail separation, grading are mostly done by female workers. They mostly work in squatting posture which is tedious and drudgerious. A participatory survey work was conducted for 107 no of female workers in two fishing industries with age in the range of 18 - 50 years. The main problems reported to be blanching of fingers (83%), pain in joints (81%), hand injury (86%), hand numbness (85%), head ache (43%), eye irritation (29%), and respiratory irritation (42%) in most of the subjects. The body parts feeling discomfort are reported to be knee (92%), shoulder (77%), lower back (78%), neck (90%) etc. Generally injuries in thumb, pointer and middle finger are more and infections take in the gap between fingers due to salty water and chemicals. Protective measures like eye goggles, apron, hand gloves, shoes, and use of sitting platform can reduce the musculoskeletal disorder and fatigue during the work.

Abstract

Around Salumbar in the Udaipur district, Rajasthan, the Banded Gneissic Complex (BGC). the Aravalli metasedimentary rocks, the Dudar Gneiss and the Lakapa Granite Gneiss have been involved in the same style and sequence of muhiple deformation. The oldest rocks are the migmatites forming the BGC, which underlie the Aravalli metasediments with an unconformity marked by a conglomerate. Rare relict pre-Aravalli structures in the BGC, and the conglomerate containing gneissic pebbles provide incontrovertible evidence for a part of the BGC being the original basement. Identical structural style and sequence of the basement gneisses wilh those of the metasedimentary cover rocks, however, point to mobilization so that they could take part in the earliest deformation affecting the metasediments in a ductile manner. The Dudar Gneiss has formed by migmatization of the Aravalli rocks synkinematically with the first deformation, whereas the Lakapa Granite Gneiss has been emplaced as a syn-to late-tectonic intrusion.

Abstract

In the Precambrian terrane of central India the question of the relation between different gneiss and schist belts has not been solved. Eventhough the Tirodi gneiss is generally considered to be the basement of the Sausar Group, unequivocal sedimentological criteria are not supplemented to confirm this view. A conglomerate which belongs to the Sausar Group has been mapped at the contact of a gneissic roc in the Mansar area of Nagpur district, Maharashtra, during the present investigation. Occurrence of gneiss pebbles in this conglomerate suggests that the gneissic unit was the source of the pebbles and acted as the basement to the Sausar Group.

Abstract

The Precambrian rocks of the Mansar area, Nagpur district, Maharashtra, belong to the Sausar Group and the Tirodi Gneiss. Both these lithological units show an unconformable relation in the area, marked by a conglomerate at the base of the Sausar Group. The metasediments of the Sausar Group bear imprints of polyphase deformation. The folds of the first generation (F₁) are isoclinal with high amplitude to wavelength ratios and pervasive axial planar cleavage (S₁). The structures of the second generation are represented by WNW-ESE trending upright isoclinal folds (F₂) and axial planar crenulation cleavage (S₂). Gentle upright folds with NE-SW striking axial planes represent structures of the third generation (F₃) Superposition of F₂ folds on F₁ folds is marked by mushroom shaped interference pattern in small-scale. Because of upright isoclinal nature of F₂ folds on WNW-ESE striking axial planes, the metasedimentary bands extend in E-W direction. Slight arcuate geometry of the metasedimentary bands is the result of superposition of F₃ folds on F₁/F₂ folds.

Abstract

Metastasis, a major cause of death in cancer patients, involves the spread of a tumor or cancer to distant parts of the body as primary cancer, invasion of surrounding tissue, spread through circulation, re-invasion and proliferation in distant organs. KiSS1 is a metastasis-suppressor protein that suppresses metastases in malignant melanomas and in some breast carcinomas, without affecting tumorigenicity and also may be mediated in part by cell cycle arrest and induction of apoptosis in malignant cells. To understand the operational mechanism, structural model is always important. Therefore, in present study a complete structural analysis and three- dimensional (3D) modeling of KiSS-1 receptor, with a molecular weight of 42,586 kDa, of Homo sapiens was carried out. The 398 amino acid sequence of the KiSS-1 receptor protein was retrieved from Uniprot KB database (Acc. no: Q969F8). Based on the PDB Blast result and analysis the three-dimensional structure of KiSS-1R was predicted by using the SWISS MODEL, ESyPred 3D protein comparative modeling server. The predicted model was further assessed by Rampage, VERIFY-3D and PROCHECK graph with acceptable scores. The overall result provides evidence of good quality of model and furnishes an adequate foundation for functional analysis of experimentally derived crystal structures and also helps in understanding metastasis.

Abstract

Palaeoproterozoic rocks of the Sausar Group, central India, are exposed on the southern flank of the Satpura Mountain Belt. Mapping in different parts of this belt indicates complex evolutionary history. The presence of a volcanosedimentary unit in the basal part of the Sausar Group is reported here. The sedimentological characters of the overlying unit indicate its glaciogenic origin. Association of volcanogenic and glaciogenic rocks in the Sausar Group could be used as tectonostratigraphic tool for supercontinent assembly during Palaeoproterozoic.

Abstract

Precambrian metasediments of Parseoni area belong to the Sausar Group. These comprise of quartzite, mica schist with manganese ore and marble. The metasediments of the area show evidence of three phases of folding. The early folds (F₁) are isoclinal with an axial planar cleavage (S₁). The second folds (F₂) are tight to isoclinal with axial planar crenulation cleavage (S₂). Thcse F₂ folds have EW striking vertical axial planes and congruous pucker axis lineations. The third folds (F₃) are open upright with NS striking axial planes. An antiformal F₂ fold plunging E is mapped in the area. In the absence of any primary top-and-bottom criteria the stratigraphic succession for the area suggested by earlier workers is debatable.

Abstract

The aim of this study was to develop commercial polylactic acid (PLA), PLA + polyethylene glycol (PEG) and PLA + polybutylene adipate terephthalate (PBAT)-based biodegradable films using blown film extrusion technology. The films produced were characterized for morphological, structural, optical, mechanical and thermal properties. The haze %, tensile strength, oxygen transmission rate (OTR), water vapour transmission rate (WVTR) parameters were varied from 10.65% to 28%, 48.3 to 56.49 MPa, 194.55 to 318.25 cc/m²/day and 175 to 318.18 (gm/m²/day) respectively for developed films. The study showed that better haze properties in biofilm are achived by compatibilizing with PEG. Thermal degradation of virgin PLA takes place in a single weight loss step with degradation peak at 349.77°C compared to PLA + PBAT blended that took two weight loss step. Fouriertransform infrared spectroscopy study was used to monitor the absorption peak shifts in specific regions to determine the known functional group interactions of the PLA with various types of materials. In all the films the absorbtion peaks appeared at 1451.2–1451.7 and 2921.2–2944.3 cm^–1 corresponding to asymmetrical deformation of C–H bond. The stretching of C=O band vibration appeared at 1745.2–1745.7 cm^–1 in PLA, PLA + PEG and PLA + PBAT film. From the fracture scanning electron microscope micrographs, there was smooth surface texture for films, and no interfacial differences were visible indicating the presence of a single phase and structural integrity of the films. The developed packaging films were subjected to MA packaging study with capsicum and found to be at par with low-density polyethylene + linear low-density polyethylene in maintaining the texture, colour and overall market quality.
