ALBAR-H: Load Balancing Around Holes in Wireless Sensor Networks

In wireless sensor networks the formation of hole is inevitable because of the structure of the sensor networks. When a hole is formed reliability is decreased. With the formation of holes in sensor networks Quality of service decreases eventually. Network Coverage is an important factor to detect a specified area. In order to maintain the coverage quality of the sensor networks, we propose a light weight protocol, ALBAR-H which is a variant of ALBA-R mechanism to detect localization errors in the sensor networks. In this algorithm , healing is performed with the nodes which are located at a right distance from the hole. Performance results through ns2 show that ALBAR-H shows a better performance by finding the localization errors. DOI: 10.17762/ijritcc2321-8169.150713

Evolutionary dynamics on strongly correlated fitness landscapes

We study the evolutionary dynamics of a maladapted population of self-replicating sequences on strongly correlated fitness landscapes. Each sequence is assumed to be composed of blocks of equal length and its fitness is given by a linear combination of four independent block fitnesses. A mutation affects the fitness contribution of a single block leaving the other blocks unchanged and hence inducing correlations between the parent and mutant fitness. On such strongly correlated fitness landscapes, we calculate the dynamical properties like the number of jumps in the most populated sequence and the temporal distribution of the last jump which is shown to exhibit a inverse square dependence as in evolution on uncorrelated fitness landscapes. We also obtain exact results for the distribution of records and extremes for correlated random variables

Ethnomedicinal Observations among Forest Dwellers of the Daitari Range of Hills of Orissa, India

Studies on hill tribes’ dependence on forest for their livelihood security are few for Orissa. Ethno medicinal observations in the state with a rich diversity of medicinal plants are still meager. The present study enumerates 21 plant species belonging to 18 families used in the treatment of various diseases among the tribes of Daitari Hill ranges of Orissa. The forest dwellers usually collect those rare plants from the nearby forest which is easily accessible and the medicines are prepared under the guidance of Vaidya or the village medicine man and are applied according to the dosage prescribed by the Vaidya. So this article gives an idea about the application of traditional medicines against various common and serious diseases

Incremental Prognostic Value of Echocardiographic Strain and Its Association with Mortality in Cancer Patients

Background Left ventricular global longitudinal systolic strain (GLS) has been shown to be superior to ejection fraction in detecting subclinical dysfunction in patients with cancer and predicting mortality in patients with cardiovascular disease. Cancer-related fatigue is common in the later stages of neoplastic malignancies and may be indicative of nonovert heart failure. The aim of this study was to determine whether reduced strain by echocardiography was associated with all-cause mortality in a cancer cohort. Methods In this retrospective study, 120 patients with cancer undergoing or scheduled to undergo chemotherapy and with normal ejection fractions (>50%) underwent assessments of GLS. GLS was derived by averaging all speckle-tracking strain segments of the left ventricle. Results Over an average follow-up period of 21.6 ± 13.9 months, 57 of 120 patients died. Univariate predictors of all-cause mortality (P < .10) were Eastern Cooperative Oncology Group performance status, male sex, hematologic malignancy, β-blocker use, and GLS. Multivariate analysis of all significant univariate variables showed that Eastern Cooperative Oncology Group performance status (hazard ratio, 2.12; 95% confidence interval, 1.54–2.92; P < .001), male sex (hazard ratio, 1.93; 95% confidence interval, 1.14–3.27; P = .014), and GLS (hazard ratio, 0.89; 95% confidence interval, 0.81–0.97; P = .012) were significantly and independently associated with mortality. Stepwise analysis of the multivariate associations showed an increase in the global χ2 value after adding GLS (P = .011) to significant clinical variables. Conclusions Eastern Cooperative Oncology Group performance status, male sex, and GLS were significantly associated with all-cause mortality in patients with cancer with normal ejection fractions receiving chemotherapy. Adding GLS to significant clinical variables provided incremental prognostic information

Reverse complex predicates or something else?: The case of Hindi de ‘give’ and jaa ‘go’

“Aspectual” complex predicates (ACPs) in Hindi are formed by a sequence of two verbs that together describe a single event. The main verb is realised in root form and contributes lexical meaning, followed by a light verb which carries TAM morphology and somehow modifies the event (VMAINVLIGHT ordering). However, it has been noted that some verb-verb combinations allow a “reverse” order in which a light verb in root form precedes the main verb inflected for TAM (VLIGHTVMAIN ordering). In this paper we take the light verbs de ‘give’ and jaa ‘go’ as case studies and trace their use in standardly ordered complex predicates, as well as what look like cases of reversal. We present our initial findings and argue that the unusual VLIGHTVMAIN sequences are not simply a reordered variant of a standard complex predicate but, in fact, exhibit interpretational differences (e.g., intentionality) that stem from the initial placement and lexical semantics of directed-action de ‘give’ and directed-motion jaa ‘go’

Circle grid fractal plate as a turbulent generator for premixed flame: an overview

This review paper focuses to ascertain a new approach in turbulence generation on the structure of premixed flames and external combustion using a fractal grid pattern. This review paper discusses the relationship between fractal pattern and turbulence flow. Many researchers have explored the fractal pattern as a new concept of turbulence generators, but researchers rarely study fractal turbulence generators on the structure premixed flame. The turbulent flow field characteristics have been studied tand investigated in a premixed combustion application. In terms of turbulence intensity, most researchers used fractal grid that can be tailored so that they can design the characteristic needed in premixed flame. This approach makes it extremely difficult to determine the exact turbulent burning velocity on the velocity fluctuation of the flow. The decision to carry out additional research on the effect circle grid fractal plate as a turbulent generator for premixed flame should depends on the blockage ratio and fractal pattern of the grid. 1

Remdesivir use in pregnant women with severe COVID-19

Numerous therapeutic strategies are proposed and tested for SARS CO-V2 infection. Remdesivir is researched and proposed by various societies. Studies about efficacy and safety in pregnancy are limited. A case series of 22 pregnant women effected with severe COVID disease and who received remdesivir, over a period of 1 year from May 2020 to May 2021 is presented. The 12 antenatal and 10 post-partum women were included. Demographic factors, baseline, day 3 and day 7 blood values of haemoglobin, total leukocyte count, platelets, liver enzymes, serum creatinine and D-dimers were collected. Adverse events were reported. Pregnancy complications and foetal and neonatal complications were studied. Pre-eclampsia was the most common comorbidity. The 99% of pregnant women and 100% of postpartum women recovered from COVID disease after remdesivir use. Lab investigations did not change considerably during the week of remdesivir use, suggesting its safety. Incidence of adverse events reported is 36.3%, of these 9% are serious adverse events. There are no antenatal or post-natal complications. No incidence of teratogenicity, foetal or neonatal complications. Incidence of feto-maternal transmission was 9%. Remdesivir is effective in treating severe SARS-CoV2 infection and has safety profile in pregnancy with regard to maternal and foetal effects

Studies on biosorption of nickel using immobilized fungus, Rhizomucor tauricus

Rhizomucor tauricus, an industrial fungus, was immobilized in sodium alginate and used as adsorbent for the removal of nickel from aqueous solutions. The biosorption capacity of Ni(II) was found to be 394 mg/g of immobilized biomass. It was observed that an increase in pH from 3 to 6 increased the percent adsorption, and an increase in liquid-to-solid ratio from 2 to 10 increased the metal uptake. The percent adsorption was increased when increasing the initial metal concentration from 25 to 100 mg/L. The equilibrium biosorption data was evaluated by Langmuir, Freundlich, and Langmuir-Freundlich (L-R) isotherm models, and was best described by the Langmuir and Freundlich isotherms. FTIR analysis revealed that –NH (bending), C–H (stretching), C=O (stretching), and –OH functional groups were mainly responsible for Ni(II) biosorption. Thus, this study demonstrated that the immobilized Rhizomucor tauricus biomass could be used as an adsorbent for the treatment of Ni(II) from aqueous solution

Molecular detection of Mycobacterium tuberculosis complex in bovine blood samples

Bovine tuberculosis (bTB), predominantly caused by Mycobacterium bovis, is one of the most neglected zoonotic diseases of cattle. The lack of documented information on bTB is one of the most important hurdles in controlling the disease. The present study was carried out to detect the presence of Mycobacterium tuberculosis complex (MTBC) from blood samples of cattle presented for slaughter, using polymerase chain reaction. The study revealed presence of MTBC in seven out of 50 animals (fourteen per cent) with symptoms suggestive of bTB. The detection of the organism emphasises the need of further prevalence studies in Kerala, to implement proper control strategies
