Energy Efficient Cluster Head Selection Method in Wireless Sensor Network

Wireless Sensor Network consists of sensor nodes deployed in a network. Each node is used to send and receive the information. Sensor nodes which having the skills to sense the surroundings, to perform the computation and to interact with other sensor nodes or to the Base station .Distinctive routing protocols and algorithms are introduced to locate manner to lessen the energy consumption in most of the research . This paper gives review at synchronous transit algorithm named Ridge Method Cluster Head Selection (RMCHS), which selects efficient Cluster Heads (CHs) to the sensor network. Also the well known routing protocol LEACH is discussed in terms of its strength and limitations. In this paper our goal is to make network energy efficient by using an enhanced Cluster Head selection method based upon weight and our proposed scheme achieve quiet efficient results than previous techniques. This paper is divides into some sections

Changes in behavioural and locomotory activities of freshwater fish, Cirrhinus mrigala (Hamilton) in response to sublethal exposure of Chlorpyrifos

The aim of the present study was to analyze the impact of sub-lethal toxicity of chlorpyrifos, one of the largest market selling agrochemical on physiological parameters of teleost fish, Cirrhinus mrigala addressing the possible causative involvement in behavioural and locomotion responses. Primarily, the acute toxicity (96h LC50) test was carried out and the value calculated by probit analysis was found to be 0.44 mg L-1. Further, one-fifth, one-tenth and one-twentieth of 96 h LC50 were selected as sublethal concentrations for sub acute studies. The experiment was carried out for 21 days and the alternative behaviour was recorded in terms of Air Ingulping (AI), Operculum Beat Frequency (OBF), Surfacing Movement (SM), Vertical Hanging (VH) and Tail Beat Frequency (TBF) on duration day 2, 4, 7, 14 and 21. Significant effect of both the concentrations and duration was observed in fishes treated with selected doses of chlorpyrifos. It was found that AI, OBF, SM, VH, TBF was highest on day 7 at 0.08 mg L-1 concentration of Chlorpyrifos. The findings revealed that there is a need to control the use of chlorpyrifos because of its toxicity. All the fish avoidance tests proved to be an important predictive and sensitive biomarker in aquatic monitoring and pollution management

Characterization of sperm heparin binding proteins (HBPs) using polyclonal antibodies raised against seminal plasma HBPs: Application in buffalo bull fertility

26-33This study aimed to evaluate rabbit polyclonal antibodies raised against purified seminal plasma sperm membrance extracts (SP) heparin binding protein (HBP) for identifying HBPs in buffalo bull spermatozoa by western blotting. Anti-SP-HBP recognized 11 polypeptides in SDS-sperm membrance extracts (SME) of 31 tested bulls. Thirty one bulls were divided into G-1 (>40%) and G-II (≤40%) based on acrosome reaction. Immunoblotting revealed that HBPs of 24, 30, 38 and 43 kDa were present in 3%, 7.02%, 1.16% and 4.83% more bulls of G-I, whereas, 20 and 46 kDa HBPs were present in 13.2 and 9.65% more bulls of G-II. Immunoblotting of anti-HBP with sperm extracts of 10 bulls (22-31) indicated that 31 kDa positive bulls had 10.9% higher conception rate than 31 kDa negative bulls. Although 24 kDa HBP was detected in 10 bulls, but its expression was very weak in bull number 22, 23 and 26, which had 10.7% lower conception rate than the bulls with strong expression of 24 kDa HBP. In the present study, 17/20 kDa positive bulls exhibited 4.46% and 8.67% low conception rate than 17/20 kDa negative bulls. Mass spectrometry analysis revealed matching of 24, 31, 33 and 38 kDa proteins with MHC class 1 antigen, tRNA methyl transferase 11 homolog partial, parvalbumin alpha-like and cilia- and flagella-associated protein 99. This study suggests that buffalo bull fertility can be predicted from sperm HBP

Misdiagnosed Spontaneous Carotid Cavernous Sinus Fistula

A 63-year-old female presented to the emergency department with worsening left-sided blurry vision and diplopia. She had previously seen several physicians and had been diagnosed with common ocular conditions – keratoconus and dry eye. However, despite treatment her symptoms were worsening. By the time her true underlying diagnosis was treated, she was left with permanent vision loss. This case report discusses the presentation, diagnosis, and treatment of her rare condition

A positive depression screen Is associated with emergency medicine resident burnout and is not affected by the implementation of a wellness curriculum

Introduction: While burnout is occupation-specific, depression affects individuals comprehensively. Research on interventions for depression in emergency medicine (EM) residents is limited. Objectives: We sought to obtain longitudinal data on positive depression screens in EM residents, assess their association with burnout, and determine whether implementation of a wellness curriculum affected the rate of positive screens. Methods: In February 2017, we administered the Maslach Burnout Inventory and the Primary Care Evaluation of Mental Disorders Patient Health Questionnaire two-question depression screen at 10 EM residencies. At five intervention sites, a year-long wellness curriculum was then introduced while five control sites agreed not to introduce new wellness initiatives during the study period. Study instruments were re-administered in August 2017 and February 2018. Results: Of 382 residents, 285 participated in February 2017; 40% screened positive for depression. In August 2017, 247/386 residents participated; 27.9% screened positive for depression. In February 2018, 228/386 residents participated; 36.2% screened positive. A positive depression screen was associated with higher burnout. There were similar rates of positive screens at the intervention and control sites. Conclusion: Rates of positive depression screens in EM residents ranged between 27.9% and 40%. Residents with a positive screen reported higher levels of burnout. Rates of a positive screen were unaffected by introduction of a wellness curriculum
