The accuracy rate of laboratory reports of typhoid fever

Aims: Salmonellae organisms are a large group of enteric bacteria and their infections present an important public health problem worldwide particularly in developing countries. Regretfully, Diagnosis and laboratory report of Salmonellae organisms is not performed correctly, due to a variety of reasons. This study was designed to determine the accuracy of laboratory reports of typhoid fever in Tehran during a two year period. Methods: This descriptive study was carried out on clinical samples diagnosed as Salmonella typhi received from a number of hospital laboratories in Tehran in years 2007 and 2008. Bacterial strains were diagnosed and identified by standard differential biochemical and serology tests using poly and mono specific Salmonella antisera. Results were then compared to those reported from the hospital laboratories. Results: Among 161 samples which were suspected to contain Salmonella typhi , 60 were reported as Salmonella typhi . Standard biochemical and serology test results revealed that although samples belonged to serogroup D of Salmonella , none of them had reacted with specific Salmonella antiserum; therefore, all non-typhoidal group D Salmonella strains had been misdiagnosed as Salmonella typhi. Conclusion: The precise laboratory identification of Salmonella typhi should be emphasized, because laboratory reports with misdiagnosed Salmonella typhi may prevent physicians from taking proper supportive and curative measures and impair the treatment process.
On the implementation of a primal-dual algorithm for second order time-dependent Mean Field Games with local couplings

We study a numerical approximation of a time-dependent Mean Field Game (MFG) system with local couplings. The discretization we consider stems from a variational approach described in [14] for the stationary problem and leads to the finite difference scheme introduced by Achdou and Capuzzo-Dolcetta in [3]. In order to solve the finite dimensional variational problems, in [14] the authors implement the primal-dual algorithm introduced by Chambolle and Pock in [20], whose core consists in iteratively solving linear systems and applying a proximity operator. We apply that method to time-dependent MFG and, for large viscosity parameters, we improve the linear system solution by replacing the direct approach used in [14] by suitable preconditioned iterative algorithms.
Fuzzy Inference System Optimization by Evolutionary Approach for Mobile Robot Navigation

The problem in the autonomous navigation of a mobile robot is to define a strategy that allows it to reach the final destination and avoiding obstacles. Fuzzy logic is considered as an important tool to solve this problem. It can mimic reasoning abilities of the human being in navigation tasks. However a major problem of fuzzy systems is obtaining their parameters which are generally specified by human experts. This process can be long and complex. In order to generate optimal parameters of fuzzy controller, this work propose a learning and optimization process based on ant colony algorithm ACO and genetic algorithm operators (crossover and mutation). We present a comparison between inference system for autonomous navigation based on fuzzy logic before and after learning. The simulated results show clearly the impact of the optimization approach improves the fuzzy controller performance mainly in obstacle avoidance and detection of the shortest path.
Développements expérimentaux et numériques pour la caractérisation des champs cinématiques de la coupe de l’acier 100 CrMo 7 durci pour la prédiction de l’intégrité de surface

Aujourd'hui, les methodes de correlation d'images sont largement utilisees pour la caracterisation et le suivi temporel des essais mecaniques. Cependant dans le domaine de l'usinage, ces methodes sont tres peu employees pour l'etude en pointe d'outil de la coupe par manque d'accessibilite, de la faible taille de la zone observee et des fortes deformations dans la zone de coupe. Dans cette these, nous mettons en application la technique de correlation d'images pour l'etude et la caracterisation des champs cinematiques induits dans la matiere usinee, durant des essais de coupe conduits avec des conditions operatoires representatives des operations industrielles. Ces conditions nous ont permis de developper, en premier lieu, des outils experimentaux et numeriques. Puis, les performances du dispositif experimental ainsi que les incertitudes de correlation ont ete quantifiees. Differentes strategies d'exploitation des images ainsi que des outils numeriques pour la mesure des caracteristiques de la coupe sont proposes. Ensuite, nous avons developpe un outil de correlation d'images integree pour la mesure des efforts dynamiques grâce a un modele analytique. Pour valider l'ensemble des methodes, des essais de rabotage, d'abord dans un alliage d'aluminium, puis dans un acier 100~CrMo~7 traite thermiquement, ont ete conduits. Ils ont permis de quantifier les champs cinematiques ainsi que les caracteristiques de la coupe. Enfin ces outils ont ete appliques pour la prediction de l'integrite de surface engendree par une geometrie 3D d'outil de coupe dans le materiau dur.

Construction of an engineered strain producing cis-4L-hydroxyproline and optimization of its biotransformation

[Objective] To obtain an engineered strain producing cis-4-L-hydroxyproline and optimize the related transformation conditions. [Methods] The DNA sequence encoding cis-4-proline hydroxylase (cis-P4H) was adjusted based on the codon bias of Escherichia coli and mRNA secondary structure, an engineered strain expressing the optimized cis-P4H gene was constructed. The cis-P4H was purified by Ni-NTA column and its activity and stability were analysed. 1888 微生物学通报 Microbiol. China 2016, Vol.43, No.9 Tel: 010-64807511; E-mail: tongbao@im.ac.cn; http://journals.im.ac.cn/wswxtbcn Whole-cell catalysis was used for the production of cis-4-Hyp, then the related transformation conditions were optimized by single factor experiment and orthogonal experiment. [Results] An engineered strain was obtained to produce cis-4-Hyp. The specific activity of cis-P4H was 2.65 U/mg and the half-life period of cis-P4H was 2.32 h. When the optical density (OD600) of the cells reached up to 0.9, IPTG was added for inducing protein expression, then the cells were used for transformation system. The transformation rate from L-proline to cis-4-Hyp was more than 83.33% at the optimized condition (pH 6.5, 31 °C, 60 h). [Conclusion] The engineered strain and related transformation conditions have a good prospect for industrial application.
Mutagenesis of the tal gene-encoding transaldolase in the Cyanobacterium, Anabaena sp PCC7120

The transaldolase gene (tal) of Anabaena sp. PCC7120 was interrupted by the insertion of the interposon W. Transaldolase assays showed that the tal mutant strain possessed the same activity as the wild-type, indicating that the second copy of the gene complements the enzyme activity. Being coded by a gene (zwf) downstream of tal and probably in the same operon, glucose-6-phosphate dehydrogenase (G6PDH) activity was also analysed. Only 34% of wild-type G6PDH activity was retained in the tal mutant strain. This may have due to the polar affect of tal mutation on the transcription of the zwf gene. Growth of the tal mutant was not different than that of the wild-type in the presence of combined nitrogen, but the mutant reached the stationary phase faster than the wild-type in the absence of combined nitrogen. This was probably because of the reduction of G6PDH activity, resulting in less production of reductant and energy in heterocysts, which negatively affects nitrogen fixation and growth.
Feminism in schools: Exploring the prevention of sexual assault in school communities

This article is co-written by women from multiple Victorian Centres Against Sexual Assault (CASAs) who have been working together to implement the Sexual Assault Prevention Program for Secondary Schools (SAPPSS) in our respective regions in Melbourne. We work in long-term partnership with secondary schools to achieve one of feminism's main goals: to prevent violence against women (VAW). In this article we aim to share the lessons of working with schools and we also aim to contribute to the debate within feminism about what makes 'best practice' prevention education.
Does ridesourcing increase or decrease vehicle kilometers traveled (VKT)? A simulation approach for the case of Santiago, Chile

Many authors have pointed out the importance of determining the impact of ridesourcing on vehicle kilometers traveled (VKT), and thus on transport externalities like congestion. However, to date there is scant evidence on this subject. In this paper we use survey results on Uber use by residents of Santiago, Chile, and information from other studies to parameterize a model to determine whether the advent of ridesourcing applications increases or decreases the number of VKT. Given the intrinsic uncertainty on the value of some model parameters, we use a Monte Carlo simulation for a range of possible parameter values. Our results indicate that unless ridesourcing applications substantially increase average occupancy rate of trips and become ridesharing, the impact is an increase in VKT. We discuss these results in light of current empirical research in this area.
DYNAMICS OF BOUNDED TRAVELING WAVE SOLUTIONS FOR THE MODIFIED NOVIKOV EQUATION

In this paper, we study the bifurcations and dynamics of bounded traveling wave solutions for the modified Novikov equation by combining the factorization technique and the method of dynamical systems. We show that the corresponding traveling wave system is a singular planar dynamical system with two singular straight lines, and obtain all possible phase portraits of the system. Then we show the existence and dynamics of several types of bounded traveling wave solutions including solitary wave solutions, periodic wave solutions, compacton solutions, kink-like and antikink-like solutions. The dynamics of these new bound traveling wave solutions will significantly facilitate nonlinear wave theories. AMS Subject Classification: 35C07
Impact of drifts in edge plasma of small size divertor tokamak

The effect of poloidal E × B and diamagnetic drifts in edge plasma of Small Size Divertor (SSD) Tokamak is studied with two-dimensional B2SO- LPS-0.5. 2D fluid transport code. The simulation results show the following: 1) For normal toroidal magnetic field, the increasing of core plasma density leads to large divertor asymmetries due to poloidal E × B and diamagnetic drifts. 2) Switching on the E × B and diamagnetic drifts leads to large change in poloidal distribution of radial electric field and induced counter-clockwise circulation (flow) around the x-point. 3) Switching on the E × B and diamagnetic drifts leads to the structure of poloidal distribution of radial electric field is nonmonotonic which responsible for negative spikes. 4) Switching on the E × B and diamagnetic drifts in vicinity of separatrix leads to the structure of poloidal distribution of radial electric field that has viscous layer. 5) Switching on the E × B and diamagnetic drifts results in torque generation. This torque spins up the toroidal rotation. 6) The E × B drift velocity depends on the plasma temperature heating and doesn't depend on plasma density.
Malicious Code Detection using the Effective Preprocessing Method Based on Native API

In this paper, we propose an effective Behavior-based detection technique using the frequency of system calls to detect malicious code, when the number of training data is fewer than the number of properties on system calls. In this study, we collect the Native APIs which are Windows kernel data generated by running program code. Then we adopt the normalized freqeuncy of Native APIs as the basic properties. In addition, the basic properties are transformed to new properties by GLDA(Generalized Linear Discriminant Analysis) that is an effective method to discriminate between malicious code and normal code, although the number of training data is fewer than the number of properties. To detect the malicious code, kNN(k-Nearest Neighbor) classification, one of the bayesian classification technique, was used in this paper. We compared the proposed detection method with the other methods on collected Native APIs to verify efficiency of proposed method. It is presented that proposed detection method has a lower false positive rate than other methods on the threshold value when detection rate is 100%.
Selecting for Polychronicity: Bringing Out the Best in People

A popular means of predicting multitasking success is measuring individuals’ polychronicity, which is the preference for multitasking instead of focusing on single tasks in a linear fashion. An experimental investigation of the potential problems of using polychronicity measures for personnel selection purposes was conducted. The present study discovered that measures of polychronicity are seriously flawed for use in personnel selection. Due to the ease with which the intention behind the questions can be determined, individuals are able to distort their responses to match what the job requires. Practical issues and implications for personnel selection are discussed.
Vanadium in foraminiferal calcite as a tracer for changes in the areal extent of reducing sediments

We have used the vanadium concentration in cleaned foraminiferal calcite as a tracer of seawater V changes in the past. Since the benthic flux of vanadium is sensitive to the redox po- tential of sediments, changes in the vanadium concentration of seawater should be a reflection of changes that control the redox state of sediments. V/Ca in'G. sacculifer from an eastern equatorial Atlantic core (ENO66-17GGC) is 21.6 (+_2.8) nmol V/mol Ca. This value does not change over 35 kyr, indicating that there was no measurable change in seawater vanadium levels over this period. Potential artifacts from partial dissolution are not significant based on low, constant values for foraminiferal fragmentation (6-7%) in the top 50 cm of the core: A.minor correction to account for vanadium associated with Mn carbonate overgrowths, estimated from two Caribbean cores where this mixed phase dominates the deeper V/Ca Values, - has been applied. Changes in the areal extent of anoxic and suboxic sediments are thus constrained by this constant value and the standard deviation of the measurement, +_12%. Based on a mass balance for vanadium where suboxic sedi- ments are a source and anoxic sediments are a sink to the ocean' suboxic sediments are predicted to have changed by no more than 0.5-1.5 times the current value, assuming no changein the areal extent of anoxic sediments. This correspondsto 1.3-3.5% of total ocean Sediments. Given a con- stant area of suboxic sediments, the areal extentof anoXic Sediments didonot increase by more than fivefold, or 1.5% of the ocean floor over th e past 35 kyr. The significant reductions in deep water oxygen levels and consequent changes in sedimen t redox conditions required by polar nutrient de- pletion scenarios are not reflected in the foraminiferal vanadium data over the past 35 kyr. This suggests that models which call on less or no changes in deep Water oxygen are more likely alternatives.
EFFECT OF DIFFERENT DIETARY SUPPLEMENTS ON SELECTED QUALITY INDICATORS OF CHICKEN MEAT

The aim of the study was to evaluate the effect of different feed additives (bee pollen extract, propolis extract, and probiotic) on meat quality of broiler chickens. A total of 180 one day-old broiler chicks of mixed sex (Ross 308) were randomly divided into 3 groups. Dietary treatments were as follows: basal diet, free of supplements (control group; C); basal diet plus 400 mg bee pollen extract per 1 kg of feed mixtures and 3.3 g probiotic preparation added to drinking water (group E1); basal diet plus 400 mg propolis extract per 1 kg of feed mixtures and 3.3 g probiotic preparation added to drinking water (group E2). In the experiment, the probiotic preparation based on Lactobacillus fermentum (1.10 CFU.g of bearing medium) was used. Fattening period lasted for 42 days. Feed mixtures were produced without any antibiotic preparations and coccidiostatics. Meat quality was evaluated by following technological properties: cooling, freezing and roasting loss; colour parameters based on CIELab system; and shear force. Both dietary supplementations led to decrease in cooling (p ≤0.05) and freezing (p ≥0.05) losses compared with control. On the contrary, the supplemented diet tended to increase roasting losses (p ≤0.05) and shear force values in thigh muscle (p ≤0.05). Significantly higher L* values (p ≤0.05) in breast and thigh muscles, as well as the b* values in thigh muscle, were found when broiler chickens were fed the supplements, especially bee pollen extract and probiotics. In addition, the supplements improve redness (a*) of meat. The redness of breast muscle appeared to be the most affected (p ≥0.05) by propolis extract plus probiotics supplementation, while thigh muscle had the highest value (p ≤0.05) in bee pollen extract plus probiotics supplemented group. These findings suggested that the supplements have a beneficial effect on quality of chicken meat due to positive changes in most of quality indicators investigated in the study.
Promoting human capital through social entrepreneurship:a comparative study of Indonesia and China

The hybrid model of social and profit-making enterprise has been the hallmark of social entrepreneurship. Yet, unlike the conventional entrepreneurs, social entrepreneurs seek to alter the “status quo” of mainly rural, marginalized, disadvantaged and poor citizens. Due to their relatively large proportion of rural population, Indonesia and China were selected as case studies. Even though Indonesian and Chinese social entrepreneurial activities have increased over the years and their share in economic output has been significant, their overall development and growth are encumbered by numerous barriers. Thus, it is critical to examine the supportive and suppressive factors of social entrepreneurship in these two major Asian countries. Specifically, this article focuses on social, political, cultural and economic intricacies and their implications on social entrepreneurship. This article reviews several case studies and uses secondary data to make comparison based on the theory of social entrepreneurship put forward by Dees (2001). The similarities between Indonesia and China in terms of social entrepreneurship are as follows: (a) the limited success of social entrepreneurship, (b) the prevalence of government control over micro-economic activities, (c) strong bureaucratic red tape, (d) lack of education and training, and (e) lack of resources. However, there are unique differences between Indonesia and China. Social entrepreneurs in Indonesia focused on micro-enterprises in the non-formal sector and microfinance; whereas social entrepreneurs in China put emphasis on social efficiency, autonomy and the search for better modus operandi.
An evaluation of the Goertzel Algorithm for low-power, embedded systems

The Goertzel Algorithm provides an efficient mechanism for tone detection in signal processing. However, on Wireless Sensor Network nodes, there is often not sufficient processing power to implement this using floating-point arithmetic, so fixed-point implementations are used. In this paper we compare the quality of the results for a typical audio application with different resolutions of fixed-point support using MATLAB. We also provide performance figures based on implementing this on a representative sensor node platform. Our results show that, for this application-space, 16-bit fixed-point arithmetic provides the best tradeoff of accuracy against performance. No previous work has addressed this specific aspect of implementating the Goertzel algorithm.
What is Corporation? : The Corporate Personality Controversy and Comparative Corporate Governance

The law speaks of a corporation as a 'legal person' -- as a subject of rights and duties capable of owning real property, entering into contracts, and suing and being sued in its own name separate and distinct from its shareholders. For many centuries there have been a heated controversy between corporate nominalists and corporate realists as to the 'essence' of this soulless and bodiless person. The first purpose of this paper is to end this age-old 'corporate personality controversy' once and for all. It is, however, not by declaring victory for one side or the other, but by declaring victory for both. The key to this claim is the observation that an incorporated firm is composed of not one but two ownership relations: the shareholders own the corporation and the corporation in turn owns the corporate assets. The corporation thus plays a dual role of a 'person' and a 'thing' in the system of law. This paper then shows how this person/thing duality of corporation is capable of generating two seemingly contradictory corporate structures -- one 'nominalistic' and the other 'realistic. ' The second purpose of this paper is to reexamine the theory of corporate governance. The fact that an incorporated firm is characterized by two-tier ownership structure implies that corporate managers cannot be regarded as agents of shareholders. They are instead 'fiduciaries' of the corporation. Indeed, this paper advocates the return to the pre-Law&Economics orthodoxy, maintaining that the foundation of every corporate governance system should be the managers' fiduciary duties to the corporation and that the law governing these duties should be essentially mandatory. It also argues that a variety of corporate governance systems across countries is due to the difference in governance mechanisms that supplement the costly implementation of fiduciary law by courts.
Application of Surface Electromagnetic Wave for Wireless Communication in Arctic

The article demonstrates that the conditions of LF-MF-HF radio wave propagation over the “ice-sea” structure with highly inductive impedance are more favorable than over the sea without ice because of the appearance of surface electromagnetic waves (SEW). It was determined that the conditions of radio wave propagation over ice paths depend on a frequency, ice thickness and distance from the transmitter within the 100 kHz – 5 MHz range on the paths with ice thickness from 0.6 to 2.7 meters.
Adsorption of Iron and Synthesis of Iron Nanoparticles by Aspergillus Species Kvp 12

Biosorption technology has gained tremendous importance in bioremediation and microbes could become the cheapest tool in detoxification of effluent streams. Aspergillus sp. isolated from the soil sample collected from the area near Hyderabad Metal Plating Industry, I.D. A, Balanagar, Hyderabad, India have been investigated in this study. The growth kinetics of Aspergillus sp. was studied by growing the fungi at different concentration of iron ranging between 0.2mM – 12 mM (Ferrous sulphate). The culture showed considerable inhibition of growth with iron when compared to the metal free controls. The maximum amount of iron was observed in the medium containing 3.0 mM concentration and further increase in the metal concentration was found to increase metal adsorption. Transmission Electron Microscopy analysis revealed the adsorption of iron nanoparticles on the cellwall.
