Resistance genes to sulphonamide in commensal Escherichia coli isolated from stool of patients in Mansoura University Children Hospital

Commensal bacteria have a great impact on the emergence and spread of antibiotic resistance. This emphasizes a great need to underscore the magnitude of this problem in our locality, and children are taken as a sector in this research because they are usually subjected to heavy load of antibiotic usage. This study aimed at determining sulphonamide resistance genes presence among fecal isolates of commensal Escherichia coli detected in patients attending Mansoura University Children Hospital (MUCH) and to check the value of these commensals in the appearance and transmission of antimicrobial resistance. Forty five (45) co-trimoxazole resistant E. coli were haphazardly chosen for detection of resistant determinant to sulphonamide. The methods used were antibiotic sensitivity tests by disc diffusion, detection of sul and int1 genes by PCR and conjugation assay. Co-trimoxazole resistance was found in 80.3% of the examined fecal commensal E. coli. sul2 gene recorded the highest prevalence in the examined co-trimoxazole resistant E. coli strains (73%). int1 gene was found in 62% of those isolates. 35.5% of the studied isolates had the ability to transmit genes of resistance to the recipient susceptible isolates by conjugation experiment. The recorded great prevalence of resistance genes to sulphonamide in commensal isolates of E. coli among children seems to be alarming which may indicate the future increase in the prevalence of those resistant genes in our community. This problem underlines the necessity of limitation of antibiotic usage, particularly among children. Key words: Sulphonamide resistance, Escherichia coli, sul genes, integrons.

Risk and accountability: Drivers for change in network governance. The case of school restaurants governance in a Swiss city

Abstract Growing requirements for accountability and risk management put decentralized models of public governance under pressure. This article investigates the drivers for change from a completely decentralized, network-oriented model to a more centralized, and procedural governance model of school restaurants in a Swiss city. It focuses on the pressures and challenges that this municipality faces in terms of risks and accountability in order to identify the conditions in which network governance can be successful. We applied a qualitative approach that combined conducting 25 semi-structured interviews of main stakeholders and analyzing documentation. We found that increased demand for school meals from families, the perception of increasing exposure to insufficiently managed risks associated with growing accountability requirements constitute the main drivers for change to the centralization of certain risk-sensitive, costly, and low social purpose activities, thus providing the municipality authorities with more control over the system while preserving the associative function.
Modelling Growth Of Dual-purpose Sasso Hens In The Tropics Using Different Algorithms

This study was embarked upon to evaluate body weight (BW) from age (weeks) of Sasso hens in Nasarawa State, Nigeria. A total of one hundred and eight (108) Sasso hens aged 30 weeks were randomly selected from a larger stock kept at the Livestock Farm. Fifty-four of these birds were kept on deep litter while another fifty-four were reared in battery cages. The birds in each system of management were replicated three times with eighteen birds per replicate in a completely randomized design. In both deep litter and battery cage systems, data were collected on weekly body weights of birds from week 31-52 of rearing. Only data from forty (battery cage) and forty-three (deep litter) surviving birds were eventually used for further analyses. Effect of housing system on BW was subjected to T-Test. Phenotypic correlation between body weight (BW) and age of birds was established in both systems of rearing. Linear, Quadratic, Gompertz, Artificial Neural Network (ANN) and the Classification and Regression Tree (CRT) models were used to predict BW from the age (including housing system for CRT model) of birds. There was no significant (P=0.558) difference in the total average weekly BW of birds on deep litter (3.38 ± 0.12 kg) and those in cages (3.37 ± 0.12 kg). The prediction of BW from age was best fitted using the ANN model in both the deep litter (R2 , adjusted R2 , RMSE and significance level were 87.0%, 87.0%, 0.04 and 0.000) and battery cage (R2 , adjusted R2 , RMSE and significance level were 99.0%, 99.0%, 0.01 and 0.000) systems. The CRT model, however, predicted the optimal BW to be greater than 32.5, but not above 47.5 weeks of age with R2 value of 93.4%. The present findings may be exploited in mapping out appropriate management practices geared towards increased production.

Modal Analysis of 27 mm Piezo Electric Plate for Small-Scale Underwater Sonar-Based Navigation

This work presents progress towards the development of a small-scale, purely sonar-based navigation device for a robotic fish (~394 mm long). Aperture overloading of small (5 mm diameter) ultrasonic transmitters does not allow them to be used effectively inside water. A test on a 27 mm diameter buzzer piezo plate shows promising performance under water at frequencies from 4.5 kHz to 80 kHz. ANSYS-based simulation was therefore used to find modal frequencies at higher frequencies so as to optimize this encouraging result. The simulation process also discovered several antiresonant frequencies such as 38.5 kHz, 54 kHz, and 57.5 kHz. All frequencies above the 8th harmonic (10,589.02 Hz) are out of phase with the input load except a resonance frequency of 42.5 kHz and an antiresonance frequency of 56.5 kHz. Also, the first harmonic (1,648.73 Hz) is the only frequency that gave a nodal deformation.
AN ADAPTIVE SHIP DETECTION ALGORITHM FOR HRWS SAR IMAGES UNDER COMPLEX BACKGROUND: APPLICATION TO SENTINEL1A DATA

Abstract. Real-time ship detection using synthetic aperture radar (SAR) plays a vital role in disaster emergency and marine security. Especially the high resolution and wide swath (HRWS) SAR images, provides the advantages of high resolution and wide swath synchronously, significantly promotes the wide area ocean surveillance performance. In this study, a novel method is developed for ship target detection by using the HRWS SAR images. Firstly, an adaptive sliding window is developed to propose the suspected ship target areas, based upon the analysis of SAR backscattering intensity images. Then, backscattering intensity and texture features extracted from the training samples of manually selected ship and non-ship slice images, are used to train a support vector machine (SVM) to classify the proposed ship slice images. The approach is verified by using the Sentinl1A data working in interferometric wide swath mode. The results demonstrate the improvement performance of the proposed method over the constant false alarm rate (CFAR) method, where the classification accuracy improved from 88.5 % to 96.4 % and the false alarm rate mitigated from 11.5 % to 3.6 % compared with CFAR respectively.
Novel elastomer dye-functionalised POSS nanocomposites: Enhanced colourimetric, thermomechanical and thermal properties

Nanocomposites consisting of poly(styrene-b-butadiene-b-styrene) (SBS) and polyhedral oligomeric silsesquiox- anes (POSS) were prepared using a solvent dispersion method. POSS molecules were functionalised with two dichlorotri- azine reactive dyes (CI Reactive Blue 4, CI Reactive Red 2) prior to compounding. Infrared spectroscopy confirmed func- tionalisation. Scanning electron microscopy revealed an increase in filler aggregation with concentration, with preferential phase selectivity. Ultraviolet spectroscopy and colourimetry confirmed colour uniformity and suggested that colour inten- sity could be controlled. Functionalised POSS improved thermal stability by imparting restrictions on SBS chain motions. Tensile stress-strain analysis revealed an increase in modulus with filler concentration, while creep deformation decreased and permanent strain increased with POSS content. Storage modulus, loss modulus and glass transition temperature increased with filler content due to effective SBS-POSS interaction. Nanocomposite properties were influenced by the phase the filler was dispersed throughout and the structure of the dye chromophore.
High Performance and Compact 1×3 Beam Splitter Based on Parallel Silicon Waveguide

We propose a novel and compact broadband 1×3 beam splitter (BS), which is based on optical tunneling between neighbor and parallel waveguides; thus, it is used to couple energy from one waveguide to another. This device consists of three parallel planar waveguides, in which the energy is transferred in a coherent fashion, so that the direction of propagation is maintained. For complete energy transfer to occur between the neighbor waveguides, they must have identical propagation constants. Thus, indices and height of the waveguide layers are controlled very carefully to provide matching propagation constants. The total length of BS is only about 7 μm. The simulation and analysis show that the BS for transverse magnetic (TM) light at a wavelength of 1.55 μm is designed to split incident light into three beams, whose power is 20, 34, and 18%, respectively. The wavelength bandwidth reaches up to 52 nm with an increase in wavelength from 1.49 to 1.542 μm, in which the maximum power difference of three output ports is less than 10%; moreover, the minimum is nearly 0. BS designed here particularly suits for optical communication and optical information processing.
Effects of Morphology and Topology on the Effective Stiffness of Chiral Cellular Materials in the Transverse Plane

The present study investigates the influence of topology and morphology on the effective stiffness of chiral cellular materials in the transverse plane by means of a homogenization method. For this purpose, finite element models of representative volume elements for regular hexagonal and hexagonal-chiral configurations are used and simulations are conducted to quantify how cell topology—that is, chirality inside the cell—and cell wall slenderness affect the effective stiffness. Closed form solutions for regular hexagonal square and triangular RVEs provided in the literature are then taken as a basis for model validation. The results indicate that there are drastic differences between regular hexagonal and hexagonal-chiral configurations, which can be explained in terms of deformation mechanism transformations between bending and stretching. The investigations also reveal the positive impact of cell wall slenderness on stiffness due to volumetric increase in the cell wall material resisting the deformation.
MEASURING SENSORY CONSONANCE BY AUDITORY MODELLING

A current model of pitch perception is based on cochlear filtering followed by a periodicity detection. Such a computational model is implemented and then extended to characterise the sensory consonance of pitch intervals. A simple scalar measure of sensory consonance is developed, and to evaluate this perceptually related feature extraction the consonance is computed for musical intervals. The relation of consonance and dissonance to the psychoacoustic notions of roughness and critical bandwidth is discussed.
Comparing the lipid levels of pregnant women and their neonates according to presence or absence of environmental tobacco exposure

We aimed to study lipid levels in pregnant women and their neonates according to the presence or absence of environmental tobacco exposure (ETS). The study was performed in 150 pair of mothers and neonates subjects who were divided into 2 groups: those who were exposed to ETS and those who were not. 300 blood samples were analyzed for total cholesterol, triglycerides, apolipoproteins A (Apo A) and B (Apo B), and C-reactive protein (CRP). Statistically significant differences were found in TG (60 ± 229 vs. 46 ± 204 mg/dl) and Apo A (30 ± 213 vs. 33 ± 192 mg/dl) levels between the mothers in the case group and the control group (p=0.036 and p=0.02, respectively). Apgar scores in neonates of mothers exposed to ETS were significantly lower (8 ± 1) than those for neonates of mother not exposed (9 ± 0.5) (p=0.038). Expose of pregnant women to ETS causes significant increases of their serum triglyceride and Apo A, while also increasing serum CRP and decreasing Apgar scores in their neonates.
A WATT‐level 2.3‐GHz GaAs MESFET power amplifier with gap‐coupled microstrip‐line matching topology

A one‐stage hybrid power amplifier integrated with gap‐coupled microstrip lines for impedance matching is demonstrated in this work. The gap‐coupled microstrip line amplifier module realized here can provide 15‐dB power gain, 33.5‐dBm output power, and 42% power‐added efficiency (PAE) at 2.3 GHz. The demonstrated topology is suitable in monolithic IC technology, especially in the millimeter‐wave frequency because the gap‐coupled microstrip lines can be easily compacted into small size. © 2004 Wiley Periodicals, Inc.

Unique substrate preference of Ostrea denselamellosa Lischke, 1869 (Mollusca: Ostreidae) at Haechang Bay, on the south coast of Korea

In the present study, we observed a unique association of the flat oyster, Ostrea denselamellosa obtained from a muddy substrate at Haechang Bay, the south coast of Korea in the spring of 2013. Fossilized or semi-fossilized veneriid clam shells, possibly Ruditapes philippinarum, were found adhering to the umbonal area of the flat oyster valves. This unique association of the flat oyster shells with the fossilized clam shells suggested that the flat oyster larvae utilized the clam shells as substrate during settlement. Since availability of clam shells in the muddy subtidal environment is limited, this unique substrata for the flat oyster larvae may limit recruitment of the flat oysters in the bay.
Phenology of Daphnia in a Northern Italy pond during the weather anomalous 2014

This note reports a comparison between Daphnia phenology in the weather anomalous 2014 and a previous three years period (2011-2013), in a shallow water body of Northern Italy (Bodrio del pastore III) where we recorded D. pulex. In 2011-2013, Daphnia population showed 1-2 density peaks from mid spring to early summer, it declined in July-August and did not recover, from ephippia, until the following spring. The seasonal dynamics was probably related to the species thermal tolerance. Males and ephippial females appeared at the beginning of growth season according to a typical feature of Daphnia populations from temporary habitats. The presence of the Chaoborus larvae resulted in juvenile adaptive predator-avoidance cyclomorphosis. In 2014, in the study area, mean winter air temperature was much warmer than average recorded during the past three years while it was much colder than average in July and August. This reflected the relatively rainy and cloudy summer months: the winter and summer precipitations total was above the previous three years average. In 2014, Daphnia was found all over the year and showed a maximum peak of density in November. The general increase of Daphnia was related to a shift in D. pulex population phenology, seasonal growth started earlier and lasted longer, and to the occurrence of D. longispina . Both species were identified by genetic markers and phylogenetic analyses of ND5 sequences placed isolates from the Bodrio del pastore III into the European D. pulex group. Both populations reproduced by cyclical parthenogenesis and showed cyclomorphosis. However, D. pulex produced more males and ephippial females than D. longispina. Their seasonal dynamics were quite different: D. longispina dominated in late summer while D. pulex showed the highest density in November. The presence of D. pulex in the Bodrio is important in the framework of conservation ecology especially because we have showed that it is native European strain instead of the invasive North American clone that replaced native D. pulex throughout Africa and was already recorded in Italy. We provide some indications and discuss how Daphnia phenology of shallow lakes of temperate areas may be susceptible to inter-annual variability in weather conditions.
A Study on the Volatility and Return with Reference to Stocks of Bank Nifty

Study on stock market trends has been an area of vast interest both for who wish to make profit by trading stock in the stock market. India is one of the emerging economies, which has witnessed significant developments in the stock markets during the liberalization policy initiated by the government. However, investing in banking shares include high risks which can be guided but not controlled. The banking sector is the backbone of country’s economy. This sector has given very good return to the investors in the past. But the recent financial crisis has proved, that the Banking stocks tend to be more volatile than other stocks. This paper is a humble attempt to measure the volatility of the Bank index stocks and compare it with that of the volatility of NIFTY. Stock markets, in general, are considered volatile and volatility plays a key role in measuring the riskreturn trade-offs. Estimating volatility enables the pricing of securities and, understanding stock market volatility or individual stock price volatility enables good decisions on the part of investors. Investors who are risk-averse would not be happy to invest in a highly fluctuating stock, whereas those with a thirst for riskiness would happily invest in a highly volatile market. The study evaluates the performance of banking stocks mainly to identify the required rate of return and risk of a particular stock based upon different risk elements prevailing in the market and other economic factors.

Keywords: diabetic retinopathy, fundus camera, diabetes mellitus
Food Price Shocks and Government Expenditure Composition: Evidence from African Countries

The delicacy of socio-political consequences during the recent commodities’ prices spikes has given rise to stabilising measures that might have had repercussions on public policy alternatives. This effect may be worrying for developing countries, which because of the importance of the share of imports in their households’ basket, have observed a remarkable increase of their food import bills. This paper attempts to evaluate the effect of food price shocks on public expenditure in level and composition on 47 African countries between 1980 and 2011. After solving for endogeneity issues, our results show that food price shocks positively and significantly affect total government expenditure and the share of current government consumption in the total government expenditure. More precisely, an additional one standard deviation of the food price shock increase is associated to an increase of 0.06 standard deviation of the percentage of current government consumption in the total government expenditure. Interestingly, this effect highly depends on the vulnerability level. Future studies will use more disaggregated data of fiscal variables, including those on revenue, to better assess food security policies.
