^25Mg NMR study of the MgB_2 superconductor

^25Mg NMR spectra and nuclear spin-lattice relaxation time, T_1, have been measured in polycrystalline ^25MgB_2 with a superconducting transition temperature T_c = 39.0 K in zero magnetic field. From the first order and second order quadrupole perturbed NMR spectrum a quadrupole coupling frequency nu_Q = 222(1.5) kHz is obtained. T_1T = 1090(50) sK and Knight shift K_c = 242(4) ppm are temperature independent in the normal conducting phase. The ^25Mg Korringa ratio equals to 0.95 which is very close to the ideal value of unity for s-electrons. The comparison of the experimental nu_Q, T_1T, and K_c with the corresponding values obtained by LDA calculations shows an excellent agreement for all three quantities.Comment: 4 pages including 4 eps-figures, revtex

Role of Dashamoola Shatphala Ghrita in the management of Vataja Kasa w.s.r. to Tropical Pulmonary Eosinophilia - A Clinical Study

Kasa is a very common disease of Pranavaha Srotas. When Adhoga Gati of Vata is obstructed by Dusta Doshas, it attains the Urdhva Gati and takes Sthanasamshraya in Urah Pradesha and producing to Kasa. Vataja Kasa is one among the types of Kasa, where Shuska Kasa is prominent symptom. Vataja Kasa is taken as special reference to Tropical Pulmonary Eosinophilia because of similarities of signs and symptoms. India being one of the tropical country, the prevalence of Vataja Kasa vis-à-vis Tropical Pulmonary Eosinophilia is remarkably high. The syndrome is particularly endemic in India, Sri Lanka, South East Asia and Africa and has been reported from filarial epidemic areas worldwide. In this present study an attempt is made to evaluate the efficacy of Dashamoola Shatphala Ghrita in Vataja Kasa vis-à-vis Tropical Pulmonary Eosinophilia. A minimum of 30 subjects who fulfilled the diagnostic & inclusion criteria was subjected to the intervention. The overall results in the study revealed statistically highly significant result

Embodied Energy Audit of Residential Building

Buildings consume a vast amount of energy during the life cycle stages of construction, use and demolition. Total life cycle energy use in a building consists of two components: embodied and operational energy. Embodied energy is expended in the processes of building material production, on-site delivery, construction, maintenance, renovation and final demolition. Operational energy is consumed in operating the buildings. In this paper the review is given about energy consumption of the residential building. Energy required for various materials is calculated and energy efficient alternatives are suggested. Studies have revealed the suggestion of energy efficient alternatives materials and comparison of energy consumed by using each material. Current interpretations of embodied energy are quite unclear and vary greatly as change in site source of raw materials and embodied energy databases suffer from the problems of variation and incomparability

DNA Authentication of St John’s Wort (Hypericum perforatum L.) Commercial Products Targeting the ITS Region

open access articleThere is considerable potential for the use of DNA barcoding methods to authenticate raw medicinal plant materials, but their application to testing commercial products has been controversial. A simple PCR test targeting species-specific sequences within the nuclear ribosomal internal transcribed spacer (ITS) region was adapted to screen commercial products for the presence of Hypericum perforatum L. material. DNA differing widely in amount and extent of fragmentation was detected in a number of product types. Two assays were designed to further analyse this DNA using a curated database of selected Hypericum ITS sequences: A qPCR assay based on a species-specific primer pair spanning the ITS1 and ITS2 regions, using synthetic DNA reference standards for DNA quantitation and a Next Generation Sequencing (NGS) assay separately targeting the ITS1 and ITS2 regions. The ability of the assays to detect H. perforatum DNA sequences in processed medicines was investigated. Out of twenty different matrices tested, both assays detected H. perforatum DNA in five samples with more than 103 ITS copies µL−1 DNA extract, whilst the qPCR assay was also able to detect lower levels of DNA in two further samples. The NGS assay confirmed that H. perforatum was the major species in all five positive samples, though trace contaminants were also detected

Epididymal Cyst - A Case Study

Cysts of the epididymis are usually congenital and derived from an embryonic remnant. These cysts are due to cystic degeneration of remnants of the paramesonephric or Mullerian duct and Remnants of the mesonephric duct or Wolffian duct system. Here we report a case of bilateral Epididymal cysts in a middle aged man with a complaint of scrotal lump and infertility since 15 years. He was treated with excision of the cysts under local anaesthesia and had a marked improvement in scrotal discomfort and urgency of micturition after the treatment

Maternal and foetal outcome in term patients with previous one lower segment cesarean section

Background: In modern day obstetric practice we encounter increasing number of patients with history of caesarean section because of rise in primary caesarean due to changing trends in their indications. There is increasing fear and anxiety by obstetricians for managing these cases from medico legal point of view. Present study was done to look at the feto-maternal outcome and for   appropriate mode of delivery and overall  to conduct the proper management of patients with previous one  lower segment caesarean section so as to achieve the goal of healthy mother and baby at the end of pregnancy.Methods: This is a Retrospective observational study carried out at G S Medical College and KEM Hospital, Parel Mumbai 12 Maharashtra India from January 2015 to December 2015. All patients enrolled in study were with H/O previous lower segment caesarean section. Classical CS, inverted T incision other medical complications were excluded. Patients were evaluated thoroughly by history and examination and mode of delivery was decided. Informed consent was taken of the patients who were fit for VBAC ie Vaginal Birth after caesarean section. Antenatal, intrapartum and post-partum records were evaluated. Women who were given trial of VBAC, progressed into labour spontaneously. Labour was constantly supervised by competent staff and meticulously monitored by CTG.Results: All the patients were counselled throughout their ANC period for VBAC Out of 7680 confinements 588 patients with previous one LSCS were encountered and among these patients 311 consented for vaginal birth and 277 underwent elective LSCS. From the 311 patients who consented for VBAC 165 delivered successfully 146 required Emergency LSCS. In VBAC group, 8 patients required foceps and in 2 patients required vaccum .There were 42 patients who underwent emergency LSCS for scar tenderness from which 10 patients had scar dehiscence and one patient had rupture uterus.Conclusions: Successful vaginal delivery in patients with history of previous caesarean is associated with better outcomes than emergency caesarean section and hence proper counseling in ANC period and selection of patients for trial of VBAC is necessary, especially in underdeveloped nations where limited resources and facilities of feto-maternal monitoring are available
