The electric sector contributes substantially to both greenhouse gas(GHG)and non-greenhouse gas(NGHG)emissions,which means that both conventional and thermal generation companies(GENCOs)must follow certain environmental guidelines to address various emission *** paper presents a methodology to investigate the feasibility of both GHG and NGHG emission reduction in a deregulated electricity *** proposed model takes into consideration the effect of NGHG emission cost constraints in conjunction with classical GHG emission constraints for the scheduling aspects of GENCO.A profit based self-scheduling problem with conventional fossil fueled generators and renewable energy technologies(RETs)is formulated including emission penalties and avoidance costs of GHG and NGHG emissions,***,a set of pareto solutions is evaluated for different possible scheduling scenarios.A simple,effective optimality criteria is also postulated to identify the tradeoff ***,a sensitivity analysis of various technical,environmental,as well as economic aspects is presented to examine the effect of NGHG consideration and RET inclusion in *** simulation results are presented and discussed in detail to examine the effect of NGHG consideration in self-scheduling practices of GENCO in the electricity market,thus reflecting the benefits of the proposed approach over classical emission handling approaches.

Bianchi type I string dust cosmological models in the presence and absence of magnetic field in the frame work of Lyra geometry are investigated. To get the deterministic model of the universe, we assume that the eigenvalue （σ^11） of shear tensor （σ^ii） is proportional to expansion （θ）. This leads to A = （BC）^n, where A, B, C are metric potentials and n is a constant. To discuss the results in terms of cosmic time t, we have considered n = 1. The physical and geometrical aspects＇ of the models and singularities in the models are also discussed.

BACKGROUND： With the given diversity and abundance of several targets of miRNAs, they functionally appear to interact with several elements of the multiple cellular networks to maintain physiologic homeostasis. They can function as tumor suppressors or oncogenes, whose under or overexpression has both diagnostic and prognostic significance in various cancers while being implicated as prospective regulators of age-related disorders （ARD） as well. Establishing a concatenate between ARD and cancers by looking into the insights of the shared miRNAs may have a practical relevance. METHODS： In the present work, we performed network analysis of miRNA-disease association and miRNA-target gene interaction to prioritize miRNAs that play significant roles in the manifestation of cancer as well as ARD. Also, we developed a repository that stores miRNAs common to both ARD and cancers along with their target genes. RESULTS： We have comprehensively curated all miRNAs that we found to be shared in both the diseases in the human genome and established a database, miRACA （Database for microRNAs Associated with Cancers and ARD） that currently houses information of 1648 miRNAs that are significantly associated with 38 variants supported with pertinent data. It has been made available online at http：//***/miraca/for easy retrieval and utilization of data by the scientific community. CONCLUSION： To the best of our knowledge, our database is the first attempt at compilation of such data. We believe this work may serve as a significant resource and facilitate the analysis of miRNA regulatory mechanisms shared between cancers and ARD to apprehend disease etiology.

In this paper, performance of space-time trellis-code (STTC), space-time block code (STBC), and space-time trellis-code concatenated with space-time block code (STTC-STBC) for multi-carrier code-division multiple-access (MC-CDMA) system are studied. These schemes are considered by employing different detection techniques with various multi input multi output (MIMO) antenna diversity for different number of states in multi-path fading channel. The corresponding bit error rate (BER) is obtained using simulation for minimum mean-square error (MMSE), maximum-ratio combining (MRC), and equal-gain combining (EGC) receivers employing Viterbi decoder. The simulation results show that the STTC-STBC MC-CDMA system perform better compared to other schemes considered in this paper using MMSE detection and it is also observed that the performance can also be enhanced by increasing diversity using more transmitter and receiver antennas. However, this improvement in performance comes at the cost of increased computational complexity, which is calculated for different transmitting and receiving antennas.

An approach to optimize the processing parameters to get superior ridging resistance and mechanical properties in commercial production of 430 ferritic stainless steel has been studied. Attention was also paid to improve productivity and energy saving without hampering the surface and mechanical property aspects of the material. Hot rolled coils annealed by slow cooling under insulated cover exhibit better ridging resistance than bell annealing treatment with a minor decrease in ductility. Soaking temperature prior to hot rolling has a significant effect on ridging resistance.

A simple statistical mechanical theory based on compound formation model (compound Aμ Bv formed by the preferential arrangement of A and B constituent atoms of the alloy AB, μA + νB ≒ Aμ Bv) has been used to investigate the phenomena of compound formation in NaCd liquid alloys through the study of concentration fluctuation in the long wavelength region [Scc(0)] and chemical short range order parameter (α1). The study explains the observed asymmetry successfully and suggest the existence of Cd2Na complex in the melt. The tendency of compound has been found to be weak. A tendency of inversion from segregation to order although very small, has been observed, in NaCd liquid alloys.
