The FMI (Fullbore formation microimager) log provides clear identification of wells geological characteristics. In this study, the identification and interpretation of the structures, texture, lithology, porosity, bedding, lamination, diagenetic processes, porous/non porous layers and determination of facies, sequence stratigraphy and reservoir characteristics in kangan formation, are discussed using FMI logs, thin section, core photograph and porosity logs. The Kangan lower Triassic aged carbonates formation, was deposited in the giant South Pars gas field in the Persian Gulf Basin and consists of limestone, dolomite, anhydritic dolomite, and thin shaly layers facies. The aim of this study is to provide the FMI farcies, sequence stratigraphy and subunits reservoir characteristics changes of Kangan Formation. Based on FMI logs and comparing with thin section, core photograph and porosity logs introduced 12 FMI facies(FF) in kangan formation (Table1). Three major composite depositional sequences have then been defined: K1A, K1B and K2A. They have been further subdivided into 12 depositional units, 6 tight (low reservoir characteristics) and 6 conductive (high reservoir characteristics).

The Kunbi of Uttara Kannada District are divided into two endogamous groups namely Kunbi and Atte Kunbi. They have migrated from Goa and entered Karnataka State through the Coastal region. They are settled down in the five taluks of Uttara Kannada District namely Yellapur, Joida, Karwar, Ankola and Haliyal. They live in the remote parts of the forest. When the somatometric measurements of Kunbi males compared with males of the local population of the present study show significant differences in the majority of the measurements. Thus, Kunbi somatometrically represent different groups in Karnataka.

This paper focuses on reviewing the various Steganography techniques that have been reported by researchers and scientists in the literature. The motivation of this paper is to overview the past and current Steganography techniques to embed the Stego image which bypass the human visual system without being detected. The techniques which operate both on text and image are considered. The focus is also given for the use and future scope of these techniques. The techniques are reviewed on the parameters of security, peak signal to noise ratio of stego image, mean square error and the capacity of data that can be carried out on the network without being detected. The paper is divided in three major sections which are the implementation in spatial domain, frequency domain, adaptive or mixed technique

Phytochelatins (PCs), are enzymatically synthesized Cys-rich peptides, found widely distributed in the plant kingdom and was the functional equivalent of metallothioneins (MTs). Synthesis of PC was activated by the exposure to heavy metal ions like cadmium. PC may have a role in the metal ion detoxification and help in phytoremediation approach. Hence this study was focused on the structural aspects of phytochelatin protein isolated from Cynodon dactylon. Protein sequence was retrieved from NCBI protein database with gene bank id AAO138102. Various bioinformatics online tools like GOR 4, Geno3D, ProtParam, ProtScale, TmPred, EsyPred3D analysis and GlobPlot were used to predict the structure and properties of the protein. An unstable protein with 504 amino acid residues and of molecular weight of 55803.5 Daltons was identified by In Silico studies. Further analysis using a wide range of tools revealed that the protein is a structural variant of the phytochelatin protein.

Recent investigation was performed to explore the cytotoxic activity of various extracts from the leaves of Adina Cordifolia against Ehrlich Ascites Carcinoma (EAC) cell lines using different In-vitro cytotoxic assay at 200µg/ml. Results found that acetone and ethanol extract exhibited significant cytotoxic activity, but higher cytotoxic activity was found in acetone extract.

Nowadays traffic are very high near the signals to overcome long time IR sensors are used. These IR sensors are placed near the junction it senses the heavy traffic in that signals switches to green to make move on that heavy traffic vehicles. By implementing this the wastage of time can be reduced on the roads.

Abstract: The generation of solid waste has become an increasing environmental and public health problem everywhere in the world, particularly in the developing countries. The problem of inadequate solid waste management is a major environmental challenge all over the world and Tiptur town is no exception. The problem has become compounded due to technical, financial and institutional constraints and landfill sites have further contributed to environmental degradation. The present study was to investigate the heavy metal contamination of ground water sources in and around Tiptur Town . Heavy metals like Fe++, Cd, Zn, Mn, Cr, Pb and Hg estimated to analyze ground water pollution load with respect to human health concern ,since Tipturians depend on ground water for drinking purpose. In the present investigation observed result showed that iron concentration varied between a minimum of 0.03 mg/l to a maximum of 2.9 mg/l. Other trace metals Zn, Mn and Cr were within the permissible limit and Pb, Hg and Cd were below detectable level.

We have studied LRS Bianchi type-I magnetized cosmological models in the presence of scalar tensor theory proposed by Saez Ballester [1]. We assume that the dark energy (DE) is minimally interacting, has dynamical energy- density, anisotropic equation of state parameter (EoS). Exact solutions of Einstein’s field equations are obtained by assuming a special law of variation for the mean Hubble parameter, which yields a constant value of the deceleration parameter. The geometrical and physical aspects for the models are also studied.

The power dissipation in a system-level attributes to buses is increasing in VLSI circuits. Therefore reduce of power consumption in switching activity at the I/O ports can save significant save of power. Change of voltage level on the wires significant power consumptions. As the technology scaled down, the increased wire aspect ratio (height/width) reduce the spacing between individual bus wires. This resulted in the domination of coupling capacitance. There are so many techniques have been proposed to reduce the coupling activity along with the self-switching activity. Initially, Bus invert method can be applied to encode buses without prior knowledge of data statistics. Another encoding technique called “Sequence Switch Coding for low-power data transmission” (SSC) was proposed by Myungchul Yoon to minimize Self Transition activity in buses. Among the Bus Invert method and Sequence Switch Coding, the Bus Invert method has gained popularity because of its better energy reduction (upto25.45%). However, both Bus Inver and SSC bus encoding techniques reduce only self transitions and do not consider the effect of coupling transitions. Therefore, it is important to minimize the power dissipation and cross talk delay by minimizing the both self transitions and coupling transitions on bus for the fast and safe VLSI circuits. A new technique isintroduced by doing some modifications to existing SSC technique given by Myungchul Yoon et.al, to reduce the energy dissipation and delay on DSM bus through encoding the data on the bus.

Background: MammoSite Radiation Therapy System with a high dose rate brachytherapy ¹⁹²Ir source is used to deliver partial breast irradiation after a lumpectomy for early stage breast cancer to treat the tissue immediately surrounding the lumpectomy cavity.Materials and Methods: The spherical balloons with 4 cm to 6 cm radius have been considered filled with different mixtures of water and contrast solution in our simulation. We have used MCNP4C code to study the effect of the increased attenuation on absorbed dose value for the different glandular fraction of breast tissues.Results and discussion: We have calculated Heterogeneity Correction Factor (HCF) for various balloon diameters from 4 to 6 cm, for 0%, 20%, 50%, 70% and 100% breast glandular fraction phantom with 0%, 25%, 50%, 75% and 100% contrast concentration inside the balloon.Conclusion: The result can be used in treatment planning systems and also for computation of model dependent parameters. The calculated HCF for the Mammosite breast brachytherapy applicator are agree quite well with Clinical results which obtained by others.
