This work was carried out to determine the incidence of
Campylobacter jejuni
in selected food products in Imo state, Nigeria. Unprocessed Chicken meat, Beef and processed salad vegetables (diced ...Carrots and cabbage) were assessed for the incidence of
Campylobacter jejuni
. 600 samples were collected between August, 2017-December, 2017 from selected local Markets. The
Campylobacter jejuni
was characterized using relevant biochemical test, growth characteristics and antimicrobial susceptibility and the results were read off using ABIS online showing 99% similarity with 65% accuracy. Results show that chicken samples isolated from Ihiagwa and relief markets were positive to
Campylobacter jejuni
with a 96% and 95% incidence respectively. More beef samples from Relief market were positive compared to those from Ihiagwa market with 56% and 43% incidence respectively. On the other hand higher incidence was reported for the salad vegetables from Relief market than those from Ihiagwa market with values of 22% and 16% respectively. Also most samples from Relief Market had higher microbial load than samples from Ihiagwa market. This work stresses the need for routine checks on meat sold in markets and also recommends proper processing of meat and vegetable samples before consumption.
A 84-day study was conducted to determine the effect of combination of whole millet feeding and mannan oligosaccharides (MOS) supplementation on growth performance, serum biochemistry and relative ...organ weights of growing guinea fowl. 192 One-day-old, male guinea fowls were randomly allocated to four treatment groups of 48 guinea fowl split over six replicates of eight birds. Dietary treatments were arranged in a 2×2 factorial arrangements of two diet forms (whole millet diets (WMD) and completely ground diets (CGD)) supplemented with and without 1g/kg MOS. WMD contained similar feed ingredients as CGD except that certain quantity of millet grains (150g/kg for 1–29 days and 450g/kg for 29–84 days birds) were progressively removed and fed whole for WMD-fed group. Birds fed WMD had reduced (P<0.05) feed intake and improved (P<0.05) feed to gain ratio when compared to group fed CGD. Supplementation of MOS in diets for growing guinea fowl (29–84 days) notwithstanding the feed form resulted in increased (P<0.05) total serum protein, reduced (P<0.01) serum uric acid and cholesterol concentration. Birds fed WMD had higher (P<0.05) gizzard and thymus weights while dietary supplementation of MOS showed reduced (P<0.05) liver weights and increased (P<0.05) spleen weight. It was concluded that whole millet feeding when combined with MOS supplementation in growing guinea fowls showed improved growth performance, gizzard development, serum chemistry and positive influence on organ weights.
This work deals with the seasonal daily variation of the operating temperature of silicon solar panels under tropical atmospheric conditions, including high turbidity (Harmattan dust particles). Data ...was collected from March 2010 to July 2012 at Legon (0°11′08″ W, 5°39'04″ N) using a Davis wireless Vantage Pro2 Plus weather station monitored with the software WeatherLink®. While the 'common outdoor' operating temperature is usually set at 45 °C, it has been observed that during the harmattan season, the operating temperature of a solar panel can rise beyond 70°C.
► We modeled the NIRR-1 HEU and LEU core with two additional control rods. ► The worth of the rods is adequate to shut down the reactor. ► The inclusion of the rods does not affect the neutron flux ...in withdrawn position.
A Monte Carlo simulation of additional safety rods for NIRR-1 HEU and LEU cores was carried out using the MCNP5 version 1.6 code. Two additional safety control rods having the same material composition as the main central control rod except for the surface area were studied. The following reactor core physics parameters were determined; neutron flux distribution within the core with safety rods withdrawn, control rod (CR) worth for each rod, core excess reactivity, shutdown margin and some kinetic parameters. Results obtained indicate that it would be feasible to include two additional safety control rods to improve safety level of the MNSR with little or no modification to the existing core configuration.
BackgroundTwo randomised trials assessing the effectiveness of decompressive craniectomy (DC) following traumatic brain injury (TBI) were published in recent years: DECRA in 2011 and RESCUEicp in ...2016. As the results have generated debate amongst clinicians and researchers working in the field of TBI worldwide, it was felt necessary to provide general guidance on the use of DC following TBI and identify areas of ongoing uncertainty via a consensus-based approach.MethodsThe International Consensus Meeting on the Role of Decompressive Craniectomy in the Management of Traumatic Brain Injury took place in Cambridge, UK, on the 28th and 29th September 2017. The meeting was jointly organised by the World Federation of Neurosurgical Societies (WFNS), AO/Global Neuro and the NIHR Global Health Research Group on Neurotrauma. Discussions and voting were organised around six pre-specified themes: (1) primary DC for mass lesions, (2) secondary DC for intracranial hypertension, (3) peri-operative care, (4) surgical technique, (5) cranial reconstruction and (6) DC in low- and middle-income countries.ResultsThe invited participants discussed existing published evidence and proposed consensus statements. Statements required an agreement threshold of more than 70% by blinded voting for approval.ConclusionsIn this manuscript, we present the final consensus-based recommendations. We have also identified areas of uncertainty, where further research is required, including the role of primary DC, the role of hinge craniotomy and the optimal timing and material for skull reconstruction.
