A modified approach to the new lossless data Compression method

This paper proposed the modified approach to the new lossless data compression method. It is developed based on hiding data reversibly with a location map. It performs same as the earlier algorithm but it stands on lossless strategy where as the former approach could not do it. It can compress any kind of symbols as it operates on binary symbols. It is faster than many algorithms as it does not have any complex mathematical operations. Experimental results proved that when the symbol probability increases the algorithm shows good compression ratio

Three Dimensional Casson nanofluid Flow with Convective Boundary Layer via Stretching Sheet

The present work examined Casson nanofluid in a three-dimensional boundary layer motion via stretching sheet. The study focuses on analyzing the behavior of a Casson nanofluid, which is one type of non-Newtonian fluid. The study appears to involve solving partial differential equations related to fluid flow, heat transfer, and mass transfer. These PDEs are transformed into ordinary differential equations using standard similarity variables. To solve the ODEs, the researchers employ the Runge-Kutta-Fehlberg (R-K-F) 4th order iterative scheme. It appears that higher values of the Biot number can significantly affect the temperature and concentration profiles in the Casson liquid flow

Markets and marketing research on poverty and its alleviation: Summarizing an evolving logic toward human capabilities, well-being goals and transformation

Marketing practitioners and business scholars now view some of the world’s poorest communities as profitable growth markets. Hence a market-based approach to poverty alleviation has gathered momentum. This article traces the evolution of such a market-based approach over four decades and highlights a gradual trend away from a deficit-reduction approach (focused on constraints and justice) towards an opportunity-expansion approach (focused on capabilities and well-being). This trend is summarized in an analytical framework of human capabilities, well-being goals and transformative impact evolved from the literature. The framework is then used to analyse the practice of sanitation marketing, which has emerged as a key method in one of the highest priority domains in international development discourse – sanitation. The article concludes with a discussion of how contemporary work can further take forward the key tenets of the framework and guide the development of ‘good markets’ for the poor

Loss and grief response and perceived needs of parents with the experience of having their newborn at neonatal care units

Objective: To determine and assess the loss and grief response, and perceived needs of parents who are having their newborns in neonatal care units. Material and Methods: Qualitative, phenomenological, hermeneutic study was conducted at Neonatal care units (neonatal intensive care unit NICU/ neonatal surgical intensive care unit NSICU) AIIMS, New Delhi. Sixteen parents participated in study In-depth interview of twenty to seventy five minutes duration were conducted and documented systematically. The data were analyzed following 12 steps based on Van Manen's analysis. Results: The study found that the loss of parents was 'Anticipated' and 'Actual' related to separation from baby, loss of baby etc. Grief responses were 'psychological' e.g. tension, anger, crying, denial, bargaining, confusion, preoccupation, and 'physical' e.g. loss of appetite, sleep etc. The perceived needs were mainly, to have a 'Friendly visiting policy', 'Proper information' and 'Communication'. Conclusion: The parents of neonates admitted to neonatal care units do have loss and grief reaction, and special needs, which a nurse needs to identify and meet in order to help parents cope with the grief

Three dimensional conformal radiation therapy in prostate adenocarcinoma: Survival and rectal toxicity

Technological advances in radiation beam planning and linear accelerator based radiation delivery have led to the development of three dimensional conformal radiation therapy (3D-CRT). The 3D-CRT clinical treatment in our hospital was started in September 1998 and till December 2002, 51 patients with M0 stage prostate carcinoma were treated. Treatment method consisted of pelvis and leg immobilization, planning CT scan, marking of planning target volume and organs at risk and 3D beam plan using multileaf collimated beam shaping through beam\u2032s eye view display. Network controlled 3D conformal radiation therapy was delivered with portal image verification. The median 3D-CRT dose was 72 Gy. Of the 51 patients, 35 were followed-up till December 2002 (minimum follow-up 2 years) in whom 32 were disease free and 3 had progressive disease. Eleven patients died, 8 of progressive disease, one due to second malignancy and two of intercurrent illness. Five patients were lost for follow up during 0 - 29 months period, after 3D-CRT. The acute rectal reaction (RTOG criteria) in 51 patients was grade 0 in 4, grade I in 31 and grade II in 16. None had greater than grade II rectal toxicity. The late rectal toxicity in 49 patients who had a minimum 6 months follow-up was grade 0 in 41, grade I in 3 and grade II in 5. Our experience suggests that a dose of 72 Gy by 3D-CRT can be safely delivered to the prostate and gastrointestinal tolerance during treatment and follow-up period was excellent

Acute outcome of treating patients admitted with electrical storm in a tertiary care centre

AbstractBackgroundElectrical storm (ES) is a life threatening emergency. There is little data available regarding acute outcome of ES.AimsThe study aimed to analyze the acute outcome of ES, various treatment modalities used, and the factors associated with mortality.MethodsThis is a retrospective observational study involving patients admitted with ES at our centre between 1/1/2007 and 31/12/2013.Results41 patients (mean age 54.61 ± 12.41 years; 86.7% males; mean ejection fraction (EF) 44.51 ± 16.48%) underwent treatment for ES. Hypokalemia (14.63%) and acute coronary syndrome (ACS) (14.63%) were the commonest identifiable triggers. Only 9 (21.95%) patients already had an ICD implanted. Apart from antiarrhythmic drugs (100%), deep sedation (87.8%), mechanical ventilation (24.39%) and neuraxial modulation using left sympathetic cardiac denervation (21.95%) were the common treatment modalities used. Thirty-three (80.49%) patients could be discharged after a mean duration of 14.2 ± 2.31 days. Eight (19.5%) patients died in hospital. The mortality was significantly higher in those with EF < 35% compared to those with a higher EF (8 (42.11% vs 0 (0%), p = 0.03)). There was no significant difference in mortality between those with versus without a structural heart disease (8 (21.1% vs 0 (0%), p = 0.32)). Comparison of mortality an ACS with ES versus ES of other aetiologies (3 (50%) vs 5 (14.29) %, p = 0.076)) showed a trend towards significance.ConclusionWith comprehensive treatment, there is reasonable acute survival rate of ES. Hypokalemia and ACS are the commonest triggers of ES. Patients with low EF and ACS have higher mortality

A novel sarsasapogenin glycoside from Asparagus racemosus elicits protective immune responses against HBsAg

The aim of the present investigation was to evaluate the adjuvant potential of a novel sarsasapogenin glycoside (immunoside) isolated from Asparagus racemosus in combination with hepatitis B surface antigen(HBsAg). Various in vitro and animal derived protocols were used to determine the response of immunoside adjuvanted with HBsAg and the results were compared with alum adjuvanted with HBsAg.Several biomarkers such as antibody titre (IgG, IgG1/IgG2a) were measured in mice sera. Cell proliferation, cytokines (IL-2, IFN-� and IL-4), and lymphocyte sub-populations (CD4/CD8, CD3 and CD19)were determined in splenocytes from mice administered subcutaneously with test substances. In these cells CD4/CD8 derived IFN-� release was also determined. Macrophage preparations were used for the determination of IL-12, IFN-� and nitrite content. Seroconversion potential was compared with a standard vaccine. Acute safety evaluation of immunoside was done in mice. Effect of immunoside on red blood cell haemolysis was determined. The results have suggested that immunoside potentially enhanced anti-HBsAg immune response via augmenting Th1/Th2 response in a dose dependent manner
