Knudsen Type Vacuum Evaporation Source

Various types of resistively-heated evaporation sources are used for the vacuum deposition of materials in thin film form. However, the life of such boats or crucibles is short. This paper describes a versatile crucible for Knudsen type effusion process of evaporation for the preparation of thin films of sublimating materials, which have high vapour pressures at temperatures below 1000 degree centigrade. One representative micrograph of a thin film of CdSe obtained by vacuum evaporation from this crucible is also reported

Transmission Electron Microscope Studies of Thin Films of CdSe Vacuum Evaporated from Knudsen-Type Source

A Knudsen-type evaporation source was used for the vacuum deposition of thin films of CdSe to study their growth and microstructure on to air-cleaved KCI and mica substrates under different rates of evaporation and substrate temperatures. The conditions for the growth of epitaxial films of this material onto mica have also been established and their photoconducting properties evaluated. CdSe films prepared by this source retain their stoichiometry and compare well with those prepared by other sources of vacuum evaporation

Village Baseline Study: Site Analysis Report for Rupandehi, Madhuri Village, Nepal

This is the report of the village baseline study of Madhuri Village in the CCAFS benchmark site of Rupandehi, Nepal conducted from June 5-9, 2011 to complement an earlier household baseline survey done in the same village. Madhuri is located in the fertile area of the Indo-Gangetic Plain in Nepal yet faces challenges due to increasing populations, encroachment on forests, decreasing soil fertility, limited agriculture and animal productivity, lack of opportunities, and variable climatic conditions. Its circumstances present manageable opportunities to prevent an increase in food insecurity and further degradation natural resources. Madhuri has yet to incur any food or environmental crises

Mesonephric-like adenocarcinoma of the ovary with co-existent endometriosis: A case report and review of the literature

© 2020 The Authors Introduction: Mesonephric-like adenocarcinoma (MLA) is a rare malignant gynecologic neoplasm occurring in the uterine corpus and ovary. The morphological and immunohistochemical characteristics of MLA closely resemble that of cervical mesonephric adenocarcinomas, but whether they share a common histogenesis remains unclear. Two main theories for histogenesis of MLAs include the origination of these neoplasms from mesonephric remnants, as is the case for cervical mesonephric adenocarcinoma, versus the differentiation along a mesonephric pathway from Mullerian lesions. Case: A 67-year-old presented after a right salpingo-oophorectomy for a complex ovarian mass revealed a mesonephric-like adenocarcinoma of the ovary and endometriosis. She underwent a total abdominal hysterectomy, pelvic lymphadenectomy, and infra-colic omentectomy, and diagnosed with Stage IA mesonephric-like adenocarcinoma of the ovary. At 18 months post-operatively, the patient developed flank and abdominal pain and was found to have multiple sites of recurrent disease. She was referred to medical oncology for chemotherapy as she was not a candidate for surgical cytoreduction. Discussion: This case demonstrates the aggressive nature of ovarian MLA and the need for a multidisciplinary approach when determining the treatment. In addition, this case provides further evidence to support the theory that at least a subset of MLAs arises from a Mullerian lesion which then differentiates down a mesonephric pathway

Thyroid profile in newly diagnosed male HIV patients: a study from North Western part of India

Background: The aim of this study was to determine proportion of newly diagnosed male HIV cases with thyroid dysfunction at different levels of CD4 counts.Methods: 195 newly diagnosed male HIV patients attending medical OPD, ART centre and medical wards of SMS Medical College and Hospital, during a period of May 2012 to April 2013 were enrolled in the study. These patients were divided in three groups on the basis of CD4 cell counts. Group A: CD4 counts 500/mm3.Results: We concluded a negative correlation between the CD4 counts and serum TSH level (r = -0.382) which was significant (p-value <0.05). Overall 32 (16.41%) patients had increased TSH, 4 (2.05%) patients had decreased and 159 (81.53%) patients had normal TSH level. Plasma TSH values in group A were higher than group B and C and they were highly significant (p<.001). Mean plasma TSH values in patients of group A, B and C was 4.56±3.60 µIU/mL (range: 1.10-17.74), 2.20±1.02 µIU/mL (range:0.24-4.22) and 2.23±1.06 µIU/mL (range:0.28-4.25) respectively. (Reference normal value = 0.4-4.0 µIU/mL). There was significantly positive correlation (p-value < 0.01) found between the CD4 counts and serum free T4 levels (r = +0.378).Conclusions: This study has demonstrated a high prevalence of thyroid dysfunction in HIV infected patients of this part of country. High prevalence of thyroid dysfunction may contribute to the morbidity of the patients and have a bearing on quality of life of the HIV infected patients. Severity of hypothyroidism was correlated with decreasing CD4 cell count

Collapse dynamics of a 176Yb {}^{176}\textrm{Yb}\,-174Yb{}^{174}\textrm{Yb} Bose-Einstein condensate

In this paper, we present a theoretical study of a two-component Bose-Einstein condensate composed of Ytterbium (Yb) isotopes in a three dimensional anisotropic harmonic potential. The condensate consists of a mixture of ${}^{176}\textrm{Yb}$ atoms which have a negative s-wave scattering length and ${}^{174}\textrm{Yb}$ atoms having a positive s-wave scattering length. We study the ground state as well as dynamic properties of this two-component condensate. Due to the attractive interactions between ${}^{176}\textrm{Yb}$ atoms, the condensate of ${}^{176}\textrm{Yb}$ undergo a collapse when the particle number exceed a critical value. The critical number and the collapse dynamics are modified due to the presence of ${}^{174}\textrm{Yb}$ atoms. We use coupled two-component Gross-Pitaevskii equations to study the collapse dynamics. The theoretical results obtained are in reasonable agreement with the experimental results of Fukuhara {\em et al.} [PRA{\bf 79}, 021601(R) (2009)].Comment: 6 pages, 5 figure

Comparative effectiveness of S-adenosylmethionine and etoricoxib in newly diagnosed patients of knee osteoarthritis

Background: Knee osteoarthritis is an important cause for morbidity in elderly people. Therapy is largely symptomatic with nonsteroidal anti-inflammatory drugs which pose risk in the elderly. Methionine is natural body constituent with novel property of blunting S-adenosylmethionine (SAMe) inflammatory process and cartilage degradation. The aim of this study was to compare effectiveness of SAMe, with standard etoricoxib therapy in newly diagnosed knee osteoarthritis cases.Methods: 127 newly diagnosed knee osteoarthritis patients were randomized into two groups. 55 participants received treatment  of etoricoxib 600 mg extended release once daily for 90 days (group 1) and 72 received  etoricoxib 600 mg extended release once daily and SAMe 400 mg twice daily  for initial 15 days followed by SAMe once daily 400 mg as maintenance dose for next 75 days  (group 2). The outcomes were measured by knee injury and osteoarthritis outcome score (KOOS). Pre and post treatment KOOS scores of all cases were separately pooled to define the median for whole as well as components of KOOS parameters. Relative frequencies of cases with values around respective medians were compared by MOODS median test. Patient characteristics, disease characteristics were also examined for bearing on outcomes besides the treatment.Results: SAMe treatment was associated with significantly greater improvement in symptoms, activities of daily life, spontaneous recreational activities and the quality of life compared to etoricoxib therapy. The therapy was well-tolerated.Conclusions: The study confirms SAMe as superior therapeutic option in osteoarthritis. SAMe indeed has been reported to have specific anti-arthritic effects and promotive to general well-being
