Colonisation with extended-spectrum -lactamase-producing Enterobacteriaceae in pregnant/post-partum women: Systematic review and meta-analysis

Objectives: Maternal colonisation with extended-spectrum β-lactamase (ESBL)-producing microorganisms can lead to transmission of such pathogens to neonates, resulting in considerable morbidity. The aim of this study was to determine the global prevalence of maternal colonisation with ESBLproducing Enterobacteriaceae (ESBL-E). Methods: A systematic review of PubMed, Embase, Scopus, Web of Science and ProQuest databases as well as the grey literature was performed. Studies reporting the prevalence of ESBL-E colonisation during pregnancy or postpartum period were included. Prevalence data were grouped by geographic region. The pooled prevalence and 95% confidence interval (CI) was estimated by meta-analysis using a randomeffects model. Results: Nineteen studies with reports from 16 countries (seven studies from Africa, one study from South America, two studies from Asia and nine studies from Europe) reporting data for 7352 pregnant/ postpartum women were included. The pooled prevalence of ESBL-E colonisation was 8% (95% CI 5–10%). Prevalence estimates were 15% (95% CI 5–24%) in Africa, 6% (95% CI 4–10%) in South America, 5% (95% CI 4–6%) in Asia and 4% (95% CI 2–5%) in Europe. The pooled prevalence was higher in studies with low risk of bias (10%; 95% CI 7–13%) compared with those with high risk of bias (3%; 95% CI 2–3%). Conclusion: There was heterogeneity regarding ESBL-E colonisation rates in different continents. The pooled prevalence rate was higher in Africa compared with other areas. Given that the highest rate was observed in Africa, implementing screening efforts for ESBL-E colonisation during pregnancy may be justified. © 2019 International Society for Antimicrobial Chemotherapy.

Influence of Different Roof Design Parameters on Classrooms’ Thermal Performance in Tropical Savannah Climate of Nigeria

Hot weather conditions, seasonal rainfall, intense solar radiation and low relative humidity are the characteristics of tropical savannah climate. Building interiors become overheated in this climatic region due to the effect of heat transfer through the roofs, walls and the openings (doors and windows). The roof is one of the critical components that constitutes about 70% of the overall heat gain in buildings. In classroom buildings, uncomfortable indoor conditions affect staff and students’ teaching and learning, performance and healthy well-being. The purpose of this study is to evaluate and compare the influence of different roof design parameters on the thermal performance of classrooms within the tropical savannah climate of Bauchi city. The study will provide vital information on how to improve the indoor comfort conditions of the secondary school classrooms for better teaching and learning. The studied classrooms have the same dimensions but varied roof design parameters roof (material, colour, angle and room height). Field experiments and observation were used as tools for data collection. Measurements of indoor air temperature and relative humidity were conducted in 3 different case studied classrooms using onset HOBO data loggers (UX100-011) during the lesson periods. Physical characteristics of the classroom buildings such as; types and sizes of doors and windows, walling materials and floor finishes were observed and mapped out to better understand the role of other contributing factors. The data collected were analyzed using MS Excel software. The result indicated that the indoor temperature of the studied classrooms range from 26.890C to 29.560C. This shows that the studied classrooms were thermally uncomfortable and therefore require improvement.
Morphological variations in anatomy of suprascapular notch and its clinical significance

Introduction:Scapula is a flat triangular bone that lies on the posterior chest wall between the second and seventh ribs.The aim of this study was to determine the variations in suprascapular notch morphology and correlate it clinically. Material & Methods:The study included 150 dried adult scapulae (75 right and 75 left) irrespective of age and sex from Department of Anatomy, King George's Medical University, Lucknow, Uttar Pradesh, India.The study was done by naked eye examination carefully. With the help of a digital Vernier calipers various parameters were measured i.e. superior length of suprascapular notch, inferior length of suprascapular notch,depth of the suprascapular notch. Based on shape and size of suprascapular notch it was classified as U-shaped, V-shaped, J-shaped, suprascapular notch converted into foramen. Results:Out of 150 scapulae, 59% of suprascapular notch were ‘U’ shaped, 11 % were J shaped, 8% were V shaped, 2% were completely ossified to form suprascapular foramina. In 20% cases, no suprascapular notch was observed. Conclusion:In the present study, U shaped suprascapular notch was found to be maximum. A narrow suprascapular notch in combination with an anomalous superior transverse scapular ligament causes constriction to be considered as a risk factor for suprascapular nerve entrapment.
Bifurcations due to transition from continuous conduction mode to discontinuous conduction mode in the boost converter

We investigate the bifurcations that occur when a power-electronic converter moves from continuous conduction mode (CCM) to discontinuous conduction mode (DCM) due to on-load parameter fluctuations. We derive the discrete map and show that the map is piecewise smooth, with the special property that on one side of the borderline, the determinant is less than -1, and on the other side the determinant is zero. We develop the theory of border collision bifurcations for this special condition, and explain the bifurcations observed at the CCM-DCM transition in the current mode controlled boost converter in the light of this theory.
Spacecraft-level current-injection testing to investigate discharge coupling models

The response of a spacecraft to a surface electrostatic discharge was predicted using lumped-element modeling. Current-injection testing on an actual satellite verified the predications and characterized the transient pulses coupled into electronics boxes. These tests duplicated, very closely, and ESD (electrostatic discharge) stimulus on one of the solar panels. This work makes extensive use of STARSAT SGEMP methodology. Its ultimate objective is to develop a spacecraft-level test for engineering development of spacecraft systems and for qualification tests on fully assembled spacecraft. >
On the use of linear-prediction techniques to improve the computational efficiency of the FDTD method for the analysis of resonant structures

Linear-prediction (LP) techniques are used to accurately and efficiently compute the frequencies and damping factors of microwave resonant structures from their transient response, which was previously obtained by using the finite-difference time-domain (FDTD) method. The LP equations are formulated in terms of a total least squares (TLS) problem and are solved by using the singular-value decomposition (SVD) algorithm. This approach confers robustness to the LP method, improves the spectral resolution, and provides a simple criterion for selecting the order of the LP model. We illustrate these characteristics of the LP method by applying it to two types of problems: the determination of the propagation constants of waveguides loaded with lossy dielectrics, and the calculation of the resonant frequencies of cylindrical cavities loaded with dielectric ring resonators.
MORPHOLOGY OF CORACOID PROCESS AND GLENOID CAVITY IN ADULT HUMAN SCAPULAE

Present study carried out on the 129 dry scapulas (67 right and 62 left sides) of unknown age and sex. In scapula, the coracoid process is arising from the antero-lateral aspect of the scapula, superior and medial to the glenoid fossa. The mean value of the coracoids length was found 41.0 mm in total scapulae. The coracoids width was found 7.4 mm in total scapulae. The mean of the coraco-glenoid distance was found 23.1 in total scapulae. The Glenoid cavity is the head of the scapula. The mean value of vertical length of the glenoid cavity was found 35.0 mm in total samples. The mean value of the maximum width of the glenoid cavity was found 24.9 mm in total scapulae. The width taken of the glenoid cavity from its upper half segment was found 16.6 mm in total. Knowledge of the normal anatomy and morphometry of the shoulder joint's variant is important in the diagnosis and management of diseases of the shoulder joint.
Assessing Integrity of Weather Data for Reference Evapotranspiration Estimation

Procedures and guidelines are recommended for assessing integrity, quality, and reasonableness of measured weather data and equipment calibration for automated and electronic agricultural weather stations. The procedures include calculation of hourly and 24-h clear sky envelopes for solar radiation, validation of net radiation measurements using calculation equations, and evaluation of expected trends and relationships between air vapor content and air temperature. The procedures for creating clear sky solar radiation envelopes include equations to account for the effects of atmospheric water vapor content and sun angle. Procedures for adjusting air temperature and air vapor content data are introduced to compensate for the aridity of the weather station environment. All of the guidelines are simple and straightforward, and can serve as preliminary “filters” by which to scrutinize weather measurements and as near real-time data flagging procedures for agricultural weather networks.
Mechanisms of stress-induced voids in multi-level Cu interconnects

One of the most serious problems in Cu-based multilevel integration is the failure in stacked vias caused by stress-induced voids. In this paper, the failure mechanism of the stacked via resistance is evaluated by analyzing the effects of the conditions of deposition and annealing in electroplated-Cu (EP-Cu) and the damascene structure scheme in a 64-bit RISC microprocessor with 7 copper layers. The stress-induced void is closely related to the stress change and the volume shrinkage of EP-Cu generated during deposition and annealing. The stacked via failures can be effectively suppressed with the application of two-step deposition and annealing in the EP-Cu process at the relatively low temperature of about 200/spl deg/C and the single damascene scheme for the layer of Via-5/Metal-6.
Model and algorithms for a decision support system on the application of rescue intends in case of a beyond design-basis rapid accident of a river passenger vessel

The problem of determination of threshold values of changes in stability characteristics of a river displacement ship is studied. A model and a data preparation scheme are being developed for the algorithmic implementation of the construction of curves of threshold values of lateral stability characteristics until the moment corresponding to the command given by the ship’s captain to bring life-saving appliances to a state of readiness or to use them. For the case of flooding of two adjacent hull compartments of a three-deck river passenger motor ship under the action of an external static inclining moment, illustrating data of calculations of hydrostatic characteristics and ship trim are presented, and an ensemble of diagrams of its static stability with threshold values is built. The results of the studies performed are intended for the software and hardware implementation of a digital system for active monitoring of the ship’s hull condition, predicting the development of a dangerous situation, supporting decision-making by the captain of a river vessel on the use of standard rescue equipment in the event of the threat of the ship being flooded and overturned.
Preliminary Evaluation of Effects of Herbicide Types and Rates on Growth and Yield of Cassava (Manihot esculenta Crantz)

A field experiment was conducted at the University of Uyo Teaching and Research Farm, located at Use-Offot, Uyo, Akwa Ibom State of Nigeria between September, 2007 and August , 2008.cropping season. to evaluate the effects of type and rate of herbicides on growth and yield of cassava (Manihot esculenta Crantz). The experiment was laid out in a randomized complete block design with a split plot arrangement and replicated three times. The main treatments were types of herbicides viz: Primextra (Atrazine +Metolachlor) (2-chloro-4(ethylamino-6-(isopropylamino-s-triazine and 2-chloro-N-(-2-ethyl-6-methy-phenyl-N-(2-methozylmethylethyl acetamide), Atrazine (2-chloro-4-(ethylamino)-6-(isopropylamino) s-triazine) and Diuron (N-(3,4-dichlorophenyl)-N, Ndimethlurea, while the sub-treatments were rates of application of the herbicides (1.0, 2.0, 3.0, and 4.0 kga.i ha ◌ ¹ applied as preemergence as well as control treatments where no herbicide was applied. Results showed that type and rate of herbicides had significant effects on , stand establishment, plant height leaf area index, number of tubers /stand, tuber length(cm), weight of tuber per plant and tuber yield(t/ha) at (P<0.05). Primextra at 2.0kga.i/ha had the significantly superior growth and yield (19.8tha) than Atrazine (17.3t/ha) and Diuron (16. 8t/ha). Based on the findings, this study suggests that Primextra at 2.0kga.i/ha is effective for weed control in cassava due to low phytotoxicity, better crop growth, and higher storage root yield.
Dry And Wet Seasons' Dynamics In Concentrations Of Ni, V, Cd, Pb, Mn, Fe, Co And Zn In Soil Samples Within Farm Lands In Ibeno Coastal Area, Akwa Ibom State, Niger Delta, Nigeria.

Increase in demand for crude oil, petrochemicals and natural gas have resulted in exploration for more oil wells in Niger Delta Region of Nigeria with consequent pollution of the environment. The terrestrial ecosystem and shorelines in the oil producing communities are under continuous cultivation. Environmental pollution by the industrial and domestic activities may therefore have far reaching implication on the agricultural productivity of the area and multiplier effect on the socio-economic wellbeing of people. It is on this background that this investigation ―Dry and wet season's dynamics in concentrations of Ni, V, Cd, Pb, Mn, Fe, Co and Zn in soil samples within farmlands in Ibeno Coastal Area, were investigated using atomic absorption spectrophotometer Unicam 939 model was carried out. The rank profile of mean concentrations of the heavy metals in mg kg -1 in the soil samples during dry and wet seasons was : Fe (12.09±4.98) > Mn (9.66 ± 2.18) > Zn (0.50±0.26) > Co (0.27±0.27) > Pb (0.26±0.39) > Ni (0.05±0.03) > V (0.04±0.01) > Cd (0.04±0.02) and Fe (12.09±4.98) > Mn (9.66 ± 2.18) > Zn (0.50±0.26) > Co (0.27±0.27) > Pb (0.26±0.39) > Ni (0.05±0.03) > V (0.04±0.01) > Cd (0.04±0.02) respectively. The concentrations of iron ranked the highest in both seasons. The amounts of the heavy metals in soil samples were higher in dry season than wet season. The pollution consequences of investigated heavy metals as well as their attendant health hazards on humans, livestock and economic crops have been discussed based on the results obtained, international standards, controls and available related literatures. All the metals investigated showed a significant increase in concentrations when compared to control samples but within maximum permissible range as recommended by World Health Organization (WHO) and Department of Petroleum resources (DPR) limits. This implies that the level of pollution of the soil of the studied area as regard the investigated heavy metals is insignificant. Hence, domestic animals, plants and human being are not at risk of contamination.
Design, Analysis and In-orbit Performance of the BILSAT-1 Microsatellite Twin Control Moment Gyroscope Experimental Cluster

Small Satellites have become useful and intelligent spacecraft with sophisticated attitude control and determination systems. However, near future missions will require for from these platforms a higher degree of agility with a simultaneous need for better efficiency. Control Moment Gyros are an ideal candidate technology with a unique capability to efficiently produce large torques and angular momentum with a small power consumption and savings in mass. The paper describes the design of an experimental payload of a two CMG cluster for an earth observation microsatellite, BILSAT-1. The two CMG cluster is analysed and simulations detail the performance features of the CMGs. Initial in-orbit results on the CMGs are presented along with a plan on future manoeuvres/experiments.
Novel read disturb failure mechanism induced by FLASH cycling

The read disturb failure mechanism reported causes unselected erased bits residing on selected wordlines to gain charge under low field conditions, causing them to appear programmed. This failure appears to be due to electron tunneling barrier lowering by positive charge trapped during program/erase cycling. The Si-SiO/sub 2/ barrier in failing bits is reduced from 3.0 eV to under 1.0 eV at 70 degrees C. The FLASH EPROM array failure rate dependence on cycling, stress voltage, temperature, and duty cycle is characterized. A low failure rate has been found for the fabrication process studied. <<ETX>>

Improvement of lithium-ion rechargeable battery (LIRB) for Electric Ships

The rapid improvement of lithium-ion rechargeable battery (LIRB) has given a powerful impetus to the development of environmentally friendly, powerful and universal for use on ships and underwater vehicles. The practice of building electric ships for many years has confirmed the effectiveness of electric propulsion for many types of vessels. Organically, electric propulsion fits into icebreakers and those vessels whose operation is associated with increased maneuvering modes and variable loads on propellers. LIRB has been actively used on ferries operating in a wide range of outdoor temperatures. On diesel-electric submarines (DES), the use of rechargeable batteries is traditional and is the main source of electricity. The subsequent development of new sources of electricity, the improvement of power semiconductor devices and microelectronics has led to the successful implementation of ideas for the construction of fully electric offshore facilities.
Status of the THALES High Efficiency Multi Stage Plasma Thruster Development for HEMP-T 3050 and HEMP-T 30250

High Efficiency Multi Stage Plasma Thrusters (HEMP-Ts) developed by THALES Electron Devices GmbH represent a new concept for ion thrusters with unique operational and performance characteristics. The particular magnetic field topology of HEMP-Ts provides stable and erosion-free operation up to high specific impulses with a low amount of thermal losses and allows for a compact a nd robust design. The instant-on properties and the absence of discharge instabiliti es strongly facilitate the propulsion system layout. Therefore HEMP-Ts are an ideal basis for cost-effective, reliable and long-life electric propulsion systems. In the past three year s, THALES has addressed two main development axes directed towards HEMP thrusters with nominal specific impulses of 3000 s: the medium power HEMP-T 3050 and the high power HEMP-T 30250 with nominal thrust and input powers of 50 mN and 1500 W and 250 mN and 7.5 kW, respectively. The activities have been performed under support form German and European Space Agency DLR and ESA. Product development is focused on the HEMP-T 3050 capable for position and orbit control of small, mid and large-size tele com satellites. Currently, a radiation cooled HEMP-T 3050 engineering model is being developed, which represents the basic design for the HEMP-T 3050 qualification and flight models. The HEMP-T 30250 has been developed to breadboard level and demonstrates the scalability of the HEMP thruster concept towards high power and thrust levels. This paper reviews the development status, operational and performance characteristics of both HEMP-T 3050 and HEMP-T 30250 thrusters and outlines further activities towards s pace-qualification.
