Ileal tuberculosis presenting with bleeding per rectum followed by perforation peritonitis: A rare presentation

Here, I present a rare case of ileal tuberculosis who was admitted with bleeding per rectum associated with fever for 4‑5 days.His Widal test was positive so was treated in the lines of enteric fever, but subsequently patient developed perforation peritonitis.On exploratory laparotomy, the whole abdominal cavity was filled with hemorrhagic fluid along with perforation at ileal segmentaround half a feet proximal to ileocecal junction and site was filled with blood clot. Ileostomy was performed but the patient hadpersistent fever beside higher antibiotics. Latter chest X‑ray of the patient showed pleural effusion on the left side, and pleural fluidanalysis showed the evidence of tuberculosis. Histopathological report of ileal segment confirmed the diagnosis of tuberculosis.The patient is responding well to antituberculosis treatment and now waiting for ileostomy closure

Shaping Employee Oriented Human Resource Policies Through Analyzing Motivational Needs

Managing Human resources is not uncommon, but what variables and factors may be really motivating an employee at workplace may be an area of interest for researchers. We have tried to explore the items which play key role in determining HR policies. With intensive literature review, researchers have laid down foundation to the conceptual and theoretical aspect of motivation and human resource management. They enlisted some variables for effective motivational techniques and sorted them in two factors, one determines human resource policies in an organization and other one determines the variables related to motivation status of the employees. The objectives of the research paper are to find out the key variables/items for effective motivational techniques to determine human resource polices and to find out whether motivational techniques may help the managers to lay down employee oriented policies.  The researchers have collected the data by random sampling technique in academic sector and scaled their responses on the 5 point Likert Scale. The data thereafter has been analyzed with the reduction of factor analysis by SPSS-12.0 Version. Key words: Employee oriented policies, effective motivation techniques, HR policies, Likert Scal

Obstructive Sleep Apnea: Beyond Obesity

Sleep disorders are of growing concern and are a major public health problem. The obstructive sleep apnea (OSA) is the most common among different sleep-related breathing disorders (SRBDs). Obesity is a known associated risk factor for the OSA but is not limited to them. OSA is also recognized in nonobese population. The description of OSA in non obese patients in the literature is sparse. The clinical presentation is similar as in obese but has few differences as far as pathophysiology and polysomnographic features are concerned. The severity of OSA in nonobese has less severe manifestations thus requires early recognition and different treatment strategy to prevent mismanagement of these patients

Improved Critical Current Density of MgB2 Carbon Nanotubes (CNTs) Composite

In the present study, we report a systematic study of doping/ admixing of carbon nanotubes (CNTs) in different concentrations in MgB2. The composite material corresponding to MgB2+ x at.%CNTs (35 at.% > x > 0 at.%) have been prepared by solid-state reaction at ambient pressure. All the samples in the present investigation have been subjected to structural/ microstructural characterization employing XRD, SEM and TEM techniques. The magnetization measurements were performed by PPMS and Tc & Jct measurements have been done by the four-probe technique. The microstructural investigations reveal the formation of MgB2-CNTs composites. A CNT connecting the MgB2 grains may enhance critical current density due to its size (~ 5-20 nm diameter) compatible with coherence length of MgB2 (~ 5-6 nm) and ballistic transport current carrying capability along the tube axis. The Jct of MgB2 samples with varying CNTs concentration have been found to vary significantly e.g. Jct of the MgB2 sample with 10 at.% CNT addition is ~2.3 x 10^3 A/cm2 and its value for MgB2 sample without CNT addition is ~7.2x10^2 A/cm2 at 20K. The optimum result on Jc is obtained for 10 at.% CNTs admixed MgB2 sample at 5K, the Jc reaches ~5.2 x10^6 A/cm2 in self field, ~1.6 x 10^6 A/cm2 at 1T, ~2.9 x 10^5 A/cm2 at 2.6T and \~3.9 x 10^4 A/cm2 at 4T. The high value of intragrain Jc in 10 at.% CNTs admixed MgB2 superconductor has been attributed to the incorporation of CNTs into the crystal matrix of MgB2, which are capable of providing effective flux pinning centres. A feasible correlation between microstructural features and superconducting properties has been put forward.Comment: 8 pages, 6 figures. To be published in J. Nanoscience and Nanotechnolog

Sustainable Operations in Reverse Supply Chain of Shipbuilding Business - Benefits of Green Practices

Sustainable operations have become extremely important for survival of present day shipbuilding business wherein triple bottom-line criteria – profit, planet and people, needs to be satisfied. This paper discusses about recapturing value at the end-of-life of a ship and reintroducing it to the value chain through reverse supply chain channel, thereby reducing environmental impact and also benefitting humans and ecology.  It also describes about the advantages of recycling ship vis-à-vis scrapping it in terms of environmental and human impact

Enhancement of flux pinning and high critical current density in graphite doped MgB2 superconductor

We report the synthesis and characterization of graphite (C) doped MgB2-xCx (x = 0.0, 0.1, 0.2 and 0.3) samples. The crystal structure and microstructural characterization have been investigated by x-ray diffractometer and transmission electron microscopic (TEM) analysis. The superconducting properties especially Jc and Hc2 have been measured by employing physical property measurement system. We found that the graphite doping affects the lattice parameters as well as the microstructure of MgB2 superconductor. In case of optimally doped (x=0.1) sample, the critical current density at 5K corresponds to 1.1 x 10^6 and 5.3 x 10^4 A/cm^2 for 3T and 5T fields respectively. The upper critical field has been enhanced nearly two times after doping. The flux pinning behavior has been investigated by flux pinning force density curve and it reveals that the flux pinning behaviour has improved significantly by doping. TEM micrographs show the graphite nanoparticles of size ~5-10 nm which are invariably present in MgB2 grains. These nanoparticles act as flux pinning centre and are responsible for enhancement of superconducting properties of MgB2.Comment: Accepted in "Journal of Applied Physics

Vitamin A Administered with measles vaccine to nine-month-old infants does not reduce vaccine immunogenicity

After a report of reduced seroconversion to measles in infants, aged 6 mo, given vitamin A with their measles vaccination, serious concerns were raised regarding the safety of the WHO's recommendation that infants be supplemented with vitamin A at the time of measles immunization. To determine the impact of coadministered vitamin A on the antibody response to measles vaccine given to infants aged 9 mo, the more common age for immunization in developing countries, we conducted a randomized, double-blind, placebo-controlled trial in an urban slum community in Delhi. Infants (618) were randomly allocated to receive 30 mg vitamin A or a placebo with the measles immunization. Antibodies to measles were measured by ELISA in serum samples obtained at before (baseline) and 12 wk after immunization. Overall, the seroconversion rates did not differ between vitamin A (89.5%) and placebo (87.6%) groups. There were no significant differences in the geometric mean titers in the two groups (ratio of geometric means, 1.19; 95% confidence interval, 0.97-1.46). Among malnourished infants, the geometric mean titer was significantly greater in the vitamin A group compared to the placebo group (ratio of geometric means, 1.57; 95% confidence interval, 1.18-2.0), but seroconversion rates did not differ. There were no differences in seroconversion rates and geometric mean titers in the two study groups among the well-nourished children. These results indicate that 30 mg vitamin A does not reduce the immune response to the coadministered vaccine and, therefore, can be continued to be given safely in public health programs
