Sedimentology and Paleocurrent Study of the Early Triassic Rocks in the Ruhuhu Basin, SW Tanzania

The sedimentary succession ranging in age from Permian to Early Triassic in Ruhuhu basin was subdivided into eight informal lithostratigraphic units, identified by the symbols from K1 to K8. Manda Formation (K8) belongs to Early Triassic age and comprises two Members, i.e., Lower Kingori Member and Upper Lifua Member (150-200 m thickness). The implications of present study relate to inter and intra basinal correlations which may provide regional depositional framework from a mass of local details. Present investigation connoting the lithofacies studies in conjunction with palaeocurrent and grain size analysis of the early Triassic strata aims at interpreting the depositional environment of Lifua Member. Based on the present study, five lithofacies have been identified, namely (i) Massive matrix supported paraconglomerate (Gmm), (ii) Massive sandstone (Sm), (iii) Parallel-horizontal laminated sandstone (Sh), (iv) Planar cross-bedded sandstone (Sp) and (v) Fine silt, mud and clay (Fl). Sandstone facies (Sm, Sh, and Sp) exhibit normal grading and unimodal palaeocurrent direction. Grain size analysis indicated that the sandstones were moderately sorted, finely skewed, mesokurtic and most of the grains were silty-sand. Bivariate scatter plots suggest that the Lifua Member sandstone is of riverine environment. Lithofacies, palaeocurrent and grain size studies suggest fluvial environment dominated by sand channel deposits.

Small bowel obstruction due to subserosal endometriosis: an elusive condition

The bowel is involved in 3.8 to 37% of women with endometriosis, out of which nearly 1% present with signs of bowel obstruction to the surgeon. This report describes a case of acute small bowel obstruction in a 23 years old woman. The patient gave a history of intermittent episodes of pain abdomen and abdominal distension for the past 1 year with significant loss of weight. The menstrual cycles were normal. Although there was no history of Tuberculosis, a positive history of contact was present. The clinical and biochemical picture was suggestive of peritonitis. CECT of the abdomen revealed a long segment distal ileal stricture. With a provisional diagnosis of Tubercular Ileo-Caecal stricture perforation, a midline exploratory laparotomy was performed. The procedure consisted of right limited hemicolectomy and primary ileo-ascending anastomosis with a proximal loop ileostomy. Ileostomy was done to allow the healing of distal anastomosis and closure was done after 4 weeks. Histopathology of the resected segment of ileum revealed subserosal endometriosis. Postoperatively, the patient was not given any hormonal therapy and recovery has been uneventful over the past 1 year of follow up

Health-care-associated infection in a pediatric intensive care unit

Introduction: Health-care-associated infection (HAI) is a major cause of concern in pediatric intensive care units (PICUs) all over the world and represents an important cause of mortality and financial burden for health-care systems. Objective: The objective of this study was to describe the epidemiologic profile of children with HAI. Methods: This was a prospective surveillance study conducted in a pediatric intensive care unit of a tertiary care hospital, India. Children, admitted to PICU between December 1, 2015, and November 30, 2016, were monitored for the development of bloodstream infection (BSI), ventilator-associated pneumonia, andurinary tract infection. Results: A total of 430 patients were admitted during the study period. Of 250 eligible patients, 15 children(6%) developed 19 episodes of HAI with patient prevalence of six infections per 100 patients. Only Gram-negative bacteria were identified, Klebsiella pneumoniae was the most common organism (68.42%). Bloodstream was the most common site of HAI (n=11, 58%) followed by respiratory tract (n=6, 32%) and urinary tract (n=2, 10%). In a univariate analysis, survivors of cardiac arrest or trauma, malnourished children had an increased risk of acquiring HAI. The presence of lymphopenia (≤1000/mm3), hypercarbia (Pco2 >65 mmHg), sodium imbalance (<130 meq/L or >150 meq/L), organ dysfunctions, and length of stay before acquiring infection was all associated with an increased risk of developing HAI (p<0.05). Conclusions: BSI is the most common HAI and only Gram-negative organisms were identified in our unit

Event Driven Application Specific Prioritized Data Transmission Approach for Underwater Wireless Sensor Networks

276-282The paper presents a novel framework based on prioritized event detection for Underwater Wireless Sensor Network (UWSN). The proposed approach named Event Driven Energy Balanced Routing (EDEBR) takes the routing decision based on oceanic environment parameters (temperature, density, salinity and pressure). The approach of EDEBR considers two routing phase based on annotated parameters of Critical and Non-critical event priority. Here critical data routing phase focuses on fast and reliable delivery of data and Non-critical data routing phase focuses on the network lifetime through energy balancing technique. The proposal is evaluated and compared against the standard state-of-art protocol on the basis of following three evaluation parameters i) end to end delay, ii) Network lifetime and iii) Throughput of the network. Here in case of critical data the end to end delay is reduced this satisfies the condition for fast delivery. In case of non-critical data, the energy is conserved this enhances the overall life time. Lastly the maximum throughput is achieved in cases of critical and non-critical. Thus the proposal describes a novel routing mechanism for different priority data based on annotated critical and non-critical priorities in underwater environment. The viability of proposal for both cases critical and non-critical is validated through the simulation

Search for new particles in events with energetic jets and large missing transverse momentum in proton-proton collisions at root s=13 TeV

A search is presented for new particles produced at the LHC in proton-proton collisions at root s = 13 TeV, using events with energetic jets and large missing transverse momentum. The analysis is based on a data sample corresponding to an integrated luminosity of 101 fb(-1), collected in 2017-2018 with the CMS detector. Machine learning techniques are used to define separate categories for events with narrow jets from initial-state radiation and events with large-radius jets consistent with a hadronic decay of a W or Z boson. A statistical combination is made with an earlier search based on a data sample of 36 fb(-1), collected in 2016. No significant excess of events is observed with respect to the standard model background expectation determined from control samples in data. The results are interpreted in terms of limits on the branching fraction of an invisible decay of the Higgs boson, as well as constraints on simplified models of dark matter, on first-generation scalar leptoquarks decaying to quarks and neutrinos, and on models with large extra dimensions. Several of the new limits, specifically for spin-1 dark matter mediators, pseudoscalar mediators, colored mediators, and leptoquarks, are the most restrictive to date.Peer reviewe

Combined searches for the production of supersymmetric top quark partners in proton-proton collisions at root s=13 TeV

A combination of searches for top squark pair production using proton-proton collision data at a center-of-mass energy of 13 TeV at the CERN LHC, corresponding to an integrated luminosity of 137 fb(-1) collected by the CMS experiment, is presented. Signatures with at least 2 jets and large missing transverse momentum are categorized into events with 0, 1, or 2 leptons. New results for regions of parameter space where the kinematical properties of top squark pair production and top quark pair production are very similar are presented. Depending on themodel, the combined result excludes a top squarkmass up to 1325 GeV for amassless neutralino, and a neutralinomass up to 700 GeV for a top squarkmass of 1150 GeV. Top squarks with masses from 145 to 295 GeV, for neutralino masses from 0 to 100 GeV, with a mass difference between the top squark and the neutralino in a window of 30 GeV around the mass of the top quark, are excluded for the first time with CMS data. The results of theses searches are also interpreted in an alternative signal model of dark matter production via a spin-0 mediator in association with a top quark pair. Upper limits are set on the cross section for mediator particle masses of up to 420 GeV
