    The modern heuristic techniques mainly include the application of the artificial intelligence approaches such as genetic algorithm, particle swarmoptimization algorithm, ant colony optimization, stochastic diffusion search, differential evolution, etc. The main aspect of these techniques is theirflexibility for solving the optimization problems that have different mathematical constraints. In a power system area, the competition between theelectric utilities is gradually increased due to the deregulation of the electrical markets. For this reason, the generation expansion problem presentsitself as an important issue that needs to be considered in order to achieve reasonable economic decisions.Keywords: Genetic algorithm, Particle swarm optimization, Artificial intelligence

    Background: The study is being carried out mainly to understand the prevention of coagulation of blood after a patient undergoing various types of cardiac surgeries, using different anticoagulation therapies suitable to particular types of cardiac surgery. This study was conducted to know the types of anticoagulants prescribed to patients who have undergone different types of cardiac surgeries along with the prescribed anticoagulants. Methods: The study method used was a retrospective and prospective observational study carried out on 50 patients who underwent cardiac surgeries in the department of cardiology and medicine. Results: A total of 50 patients were enrolled for this study who satisfied the inclusion criteria, out of which 64% of patients were males, and 36% were females. The highest number of patients were found to be in between the age group of 61-70 yrs (34%), whereas age group between 51-60 yrs (28%), age group 71 and above (18%), 41-50 (14%), 21-30 yrs (4%) and 18-20 yrs (2%) respectively. Most of the patients had undergone Coronary Artery bypass grafting. It was seen that the highest Anticoagulant being prescribed was Heparin in most of the post-cardiac surgeries. Whereas drugs like dalteparin, acenocoumarol, and warfarin were prescribed the majority in valvular heart surgeries. Conclusions: Various cardiac surgeries were taken into consideration for the study. The most common anticoagulants prescribed were heparin, dalteparin, acenocoumarol, and warfarin in coronary artery bypass surgery and valvular heart surgeries respectively

    Seroma: an interesting case report

    Get PDF
    A seroma is defined as a sterile accumulation of serum in a circumscribed location in the tissue. Seromas can occur after surgeries, especially those that are extensive or involve significant tissue disruption viz. hernia repairs, plastic surgeries such as breast augmentation or reconstruction, abdominoplasties (tummy tucks)and removal of large intra-abdominal space occupying lesions like huge fibroids/ovarian masses. The literature citing the exact incidence of seromas following removal of large intra-abdominal masses is scant. Seromas at times become severely symptomatic. The best way to prevent a seroma is not to give it any place to form. It's easier said than done. Here is an interesting case report of postoperative seroma following removal of a large broad ligament fibroid

    Intrauterine insemination: a retrospective review on determinants of success

    Get PDF
    Background: To determine the prognostic factors such as female patient’s characteristics and of semen parameters on the pregnancy rate following intrauterine inseminationMethods: This study was done at Assisted Reproduction Centre, KLE’s Hospital and Medical Research Centre, Belgaum, India between June 2011 to May 2012. A total of 264 IUI cycles in which clomiphene citrate with or without human menopausal gonadotropin was used for ovarian stimulation were analysed retrospectively to identify prognostic factors regarding treatment outcome.Results: In this study the pregnancy rate was 17.25%. The logistic regression analysis of variables showed that number of follicles and total IUI cycles were significantly associated with success rate but age of the couple, duration of infertility, endometrial thickness, size of the follicles, sperm count and sperm motility did not show significant differences between pregnant and non pregnant women.Conclusions: The findings of this study showed that age of the couple, duration of infertility, endometrial thickness, size of the follicles, sperm count and sperm motility did not correlate with pregnancy occurrence in an IUI cycle but number of follicles and total IUI cycles correlated with the occurrence of pregnancy.

    Studies on the Energy Band Discontinuities in SnS/ZnMgO Thin Film Heterojunction

    AbstractTin sulfide (SnS), with a direct energy band gap of 1.3eV and high absorption coefficient >104cm-1 is a promising candidate for application as an absorber material for solar cell fabrication. Although several research groups have fabricated SnS-related solar cells, the reported efficiencies were low (< 3.0%). One of the reasons for this low efficiency is the mismatch at the band edges in the heterojunction. In the present work, SnS films have been synthesized by sulfurization of Sn layers deposited by evaporation and RF sputtering onto SnO2 coated glass. The structural properties of the layers were discussed. All RF sputtered Zn0.8Mg0.2O (ZMO) and ZnO:Ga were coated on SnS as buffer and window layers respectively. The band offsets at the SnO2/SnS and ZMO/SnS heterojunctions were evaluated using X-ray photoelectron spectroscopy measurements. The conduction band (ΔEc) and valence band (ΔEv) discontinuities were determined as approximately 1.0eV and 3.5eV for SnO2/SnS and 0.4eV and 1.7eV for ZMO/SnS junction. The related energy band diagram was constructed and the results discussed

    Objective: This work was aimed to investigate the prophylactic and therapeutic role of Indian shrimp in aluminum chloride-induced Alzheimer’s disease (AD) in rats. Methods: The male Wistar rats were selected and divided into six groups. Group I received distilled water, Group II received AlCl3 ( 100 mg/kg, p.o.), Group III received rivastigmine (1 mg/kg, p.o.), Group IV received AlCl3 + shrimp powder (200 mg/kg, p.o), and Group V received AlCl3 + shrimp powder (400 mg/kg, p.o) for 60 days. At the end of the study, various parameters such as behavioral and biochemical investigations were assessed. Results: The result of the study shows that the shrimp (400 mg/kg) has better effect on the treatment of aluminum chloride-induced AD in rats. It showed a remarkable improvement in the behavioral and biochemical parameters, and the result of histopathology study shows that the hippocampus region of brain tissue recovered as compared with control. Conclusion: From this study, it is evident that dietary intake of shrimp can help to inhibit oxidative stress produced due to the accumulation of AlCl3 in the brain and used as a prophylactic for AD

    Plasmepsin inhibitors: design, synthesis, inhibitory studies and crystal structure analysis

    Get PDF
    Plasmepsin group of enzymes are key enzymes in the life cycle of malarial parasites. As inhibition of plasmepsins leads to the parasite's death, these enzymes can be utilized as potential drug targets. Although many drugs are available, it has been observed that Plasmodium falciparum, the species that causes most of the malarial infections and subsequent death, has developed resistance against most of the drugs. Based on the cleavage sites of hemglobin, the substrate for plasmepsins, we have designed two compounds (p-nitrobenzoyl-leucine-β -alanine and p-nitrobenzoyl-leucine-isonipecotic acid), synthesized them, solved their crystal structures and studied their inhibitory effect using experimental and theoretical (docking) methods. In this paper, we discuss the synthesis, crystal structures and inhibitory nature of these two compounds which have a potential to inhibit plasmepsins
