In order to solve the reliability assessment of repairable systems, this article, based on two-component system, provides the maximum likelihood estimation. The system can be restored through proper repairing even from Common Cause Shock (CCS) failure. We derived M L estimates of availability for series and parallel systems. The approach used is empirical one with Monte Carlo simulation.

Lifestyle of Kaani tribes encompasses a variety of aspects. The scope of the present study was to find out the socioeconomic status of the community living within the forest and those who have moved out to the surrounding villages and towns. Kaani women are involved in selling of herbs and plants that are available near forest boundaries. Organic compost is used for the agriculture. The forest serves as valuable sources for the economic activity. Collection of minor forest produce is a daily routine for them. Although agriculture was seen to be the most major employment, very few adult women were occupied in agriculture for their source of income. The present study was confined to adults’ age range 25 – 45 as it would reflect the influence of their food culture and environmental factors. Special attention is required to know their current situation to focus on development of the tribal areas and tribal peoples.

Soret effect on unsteady MHD flow past an impulsively started inclined oscillating plate with variable temperature and mass diffusion is studied here. The fluid taken is electrically conducting. The Governing equations involved in the present analysis are solved by the Laplace-transform technique. The velocity and concentration profile is discussed with the help of graphs drawn for different parameters like thermal Grashof number, mass Grashof Number, Prandtl number, soret parameter, phase angle, the magnetic field parameter and Schmidt number.

This article presents the Marital Psycho-Spiritual Intervention (MP-SI), which provides the married couples and helping professionals with knowledge and skills for strengthening marriage relationships. MP-SI is an intervention that specifically developed to help Muslim married couples build a close relationship with Allah SWT, with themselves, and with their respective couples. This intervention is a structured format. In each session, the participants are exposed to the knowledge of Islamic marriage. The content of this intervention takes into account the content of the Holy Quran on man’s creation, which consisted of four important elements, nafs (soul), aql (intellect), qalb (heart), and ruh (spirit). The participants are exposed to effective communication skills, worked as teams to resolve problems, managed conflicts without decreasing closeness, preserved, and enhanced attachment through communication elements, conflict resolutions, forgiveness, sakinah (tranquility), mawaddah (love with passion), and rahmah (mercy). This intervention may be applied in counseling and coaching interventions, as well as relationship education, couples’ workshops and retreats.

The structural and tectonic analysis of Okposi and environs, Lower Benue Trough using Landsat-TM data was carried out with the aim of carrying out a detailed structural interpretation of the study area by identifying the lineaments associated with the study area and inferring their effect on the economic potentials of the study area. In addition, this study was aimed at determining whether the Okposi Brine Lake in the study area is structurally controlled. Several GIS softwares which include the ILWIS 3.1 Academic were used to analyze the data. Simple digital image processing techniques were applied on the data to enhance edges of linear features, followed by computer aided visual interpretation. Results revealed that high lineament frequencies/density were obtained in areas where basement rocks outcrop or are closer to the surface whereas low lineament frequencies are characteristics of areas with deeply buried basement rocks. Similarly, the absence of visible lineaments in parts of the area may not be indicative of complete absence of geological structures. Trend analysis of the lineaments computed by plotting the strikes and lengths of all the lineaments revealed on the image on a rose diagram revealed structural trends in the E-W, N-S, NW-SE and NE-SW directions with the NW-SE and NE-SW directions as the dominant trends. The NE-SW linear structures observed from the study are believed to be the continental extension of the known pre-Cretaceous trans-Oceanic Fracture Zones viz. Charcot and Chain Fracture Zones. The numerous lineaments in the study area make the region viable for mineral prospecting. Finally, the presence of a lineament zone around Okposi area may be responsible for the formation of the Okposi Brine Lake. It is believed that this linear feature must have cut through the basinal brine of the Asu River group of the Benue Trough.

The spin coating method was used for the preparation of ZnS, Mn doped ZnS (MZS) and Cobalt doped ZnS (CZS) thin films and their structural and optical properties were studied. The ZnS thin films were grown on well cleaned glass substrates by spin coating method from aqueous solution of Zinc Sulphide and Thiourea with two different dopants Mn and Co. The properties of ZnS, MZS and CZS thin films and their growth mechanisms were studied using x-ray diffraction, UV-Visible spectroscopy, photoluminescence and VSM studies. Effect of dopants on structural, optical and magnetic properties was reported. Keywords: ZnS, Spin Coating, Dopants, Structural, Optical and magnetic properties.

Bio-metric identification systems are widely used for unique identification of humans mainly is verification and identification .It is used as a form of identity access management and access control. Fingerprint identification is one of the best biometric technique. The biometric fingerprints identification are secure to use and mainly unique for every person and do not change in one’s lifetime. This paper is to identify each and every student of the department as well as the college.

In this work Cadmium Sulphide/Porous Silicon (CdS/PS) nanocomposite structure was successfully synthesized by depositing CdS film over PS substrate at room temperature. CdS was incorporated into the pores of PS and thereby making a protecting layer. The XRD, SEM, FTIR and PL analysis were carried out to characterize the CdS/PS structure. XRD result suggests the formation of CdS hexagonal structure on PS surface. The diffraction peaks pertaining to PS along with those corresponding to CdS were observed. The surface morphology of the prepared CdS/PS layer was studied by SEM analysis. The information about the vibration and rotation of molecular groups and the bonding of inorganic molecules on silicon surfaces are confirmed by transmission FTIR spectra. The PL measurements on CdS/PS structure show emission peaks at around 620 & 660 nm with 2.0 & 1.9 eV band gap respectively. These results show the incorporation of CdS into the pores of PS and capable of utilizing for device applications. Keywords: CdS/PS, XRD, SEM, FTIR, PL

The term “producer” rather than “farmer” because it covers all aspects of agricultural production, including livestock and fisheries, and the processing of agricultural products on-farm or in the rural areas (such as the women’s cottage industries). The producer organizations (POs) considered are formal rural organizations whose members organized themselves with the objective of improving farm income through improved production, marketing, and local processing activities. POs deal with: policies on issues such as pricing and export and import of agricultural products; improvement of agricultural production practices; access to inputs and services, including agricultural credit; marketing of agricultural production; and local processing of agricultural production and its marketing. Collectivization of producers, especially small and marginal farmers, into producer organizations has emerged as one of the most effective pathways to address the many challenges of agriculture but most importantly, improved access to investments, technology and inputs and markets. Department of Agriculture and Cooperation, Ministry of Agriculture, Govt. of India has identified farmer producer organization registered under the special provisions of the Companies Act, 1956 as the most appropriate institutional form around which to mobilize farmers and build their capacity to collectively leverage their production and marketing strength. It has been argued that rural producer organizations (RPOs) are an effective tool for solving problems in rural areas and promoting agricultural development. The empirical evidence of the effectiveness of POs on serving their members is scarce at best.

We have studied the relationship between suicide in Slovakia and various Solar, Interplanetary and Geomagnetic Activity parameters, such as Sunspot Numbers (SSN), Solar Flare Index (SFI), Sudden Storm Commencements (SSC), and planetary Ap, Kp and Dst Indices observed during the period of 1986 to 2010. The data shows that the number of deaths due to suicide of males and females is well correlated with the yearly mean of Sunspot Numbers (SSN), Solar Flare Index (SFI), Sudden Storm Commencements (SSC), and planetary Ap, Kp and Dst Indices. We have calculated a large positive correlation, with correlation coefficients of 0.72, 0.64, and 0.62, between the yearly total number of male deaths due to suicide and the Planetary Kp, Ap, and Dst (magnitude) Indices. In addition, we have found a large negative correlation, with correlation coefficients -0.77, -0.68, and -0.60, between the yearly total number of female deaths due to suicide and the Planetary Kp, Ap, and Dst (magnitude) Indices. A large positive correlation, with a correlation coefficient of 0.60, and a good medium positive correlation, with correlation coefficient 0.57, has been found between the yearly total number of male deaths due to suicide and the yearly mean of the SSN and SFI. A good medium negative correlation, with correlation coefficients -0.49 and -0.40, has been found between the yearly total number of female deaths due to suicide and the SSN, SFI. From the statistical analysis of sudden storm commencements (SSC), and death due to suicide, we have obtained a positive correlation, with correlation coefficient of 0.51, between the yearly total number of male deaths due to suicide and Sudden Storm Commencements (SSC), as well as a negative correlation, with a correlation coefficient of -0.38, between the yearly total number of female deaths due to suicide and Sudden Storm Commencements (SSC).
