Impact and efficacy of Child Psychiatric Rehabilitation Services on Children ’ s Functional Outcomes , Qatar

Behavioral interventions are recommended as treatments for children with psychiatric disorders. Recent policies relating to child mental health in many countries appear to focus more on policing and assessing the numbers of children affected, and supporting the needs of child in this era. Relatively little is known about the management effectiveness and functional outcomes of child rehabilitation. This study was conducted to gain knowledge of changes of functioning and disability over time at rehabilitation services provided to children with psychiatric elements and compare functional gains by age and diagnosis. A prospective multicenter cohort design was used. Children presented at rehabilitation center and received management during the period from December 2010 to July 2016 were enrolled. Statistical analyses were used to compare functional gains across impairment groups and to examine the relationship between timing of intervention and functional gains. A total of 227 patients (171 males and 56 females) were enrolled in the current study. Their mean age was 8.66 ± 2.81 years (Range, 1 to 17 years). The majority 150 (66.1%) were from age group 6 to 10 years. The pattern of psychiatric disorder were variable. Chi square revealed significant differences in functional gains among patients with Asperger’s syndrome, Learning disability, Attention Deficit Hyperactivity Disorders (ADHD), and Autism as p values were p=0.000, p=0.009, p=0.01, and p=0.03 respectively. Children less than 11 years of age had made significantly larger gains in all areas of function (p=000). The value of this study’s analyses on educational experiences and outcomes of children with special educational needs. The majority of children receiving rehabilitation improve in the area of self-care, mobility, and cognition.
D ec 2 01 0 Engineering Optimisation by Cuckoo Search

A new metaheuristic optimisation algorithm, called Cuckoo Search (CS), was developed recently by Yang and Deb (2009). This paper presents a more extensive comparison study using some standard test functions and newly designed stochastic test functions. We then apply the CS algorithm to solve engineering design optimisation problems, including the design of springs and welded beam structures. The optimal solutions obtained by CS are far better than the best solutions obtained by an efficient particle swarm optimiser. We will discuss the unique search features used in CS and the implications for further research. Reference to this paper should be made as follows: Yang, X. -S. , and Deb, S. (2010), “Engineering Optimisation by Cuckoo Search”, Int. J. Mathematical Modelling and Numerical Optimisation, Vol. 1, No. 4, 330–343 (2010).
Innovative method of experimental identification of the deformation of vehicle tyres

The state of the art in the field of transducers and tyre deformation measurement methods tells of the high importance of this issue. The “tyre deformation” may be analysed from the point of view of both the global deformation of the tyre structure and the local deformation of single tread lugs. So far, there is no all-purpose transducer that would be capable of identifying simultaneously all the tyre deformation components that would be interesting for researchers in all the above aspects. If it is considered sufficient to define the tyre deformation by the value of displacement of a selected tyre point in relation to the wheel rim, then the deformation can be measured with the use of a device built in accordance with the original concept presented in this article, i.e. a mechanical contacting transducer. The transducer is intended to measure the tyre deformation by separately determining the three principal (tangential, lateral, and radial in relation to the wheel disc) deformation components, which are to be recorded at the same time. The article presents a general mathematical model of the device, with highlighting the diversity of methods of describing the model in a formal way and illustrating them by possible examples. Illustrative different paths of implementing the concept of the device have been shown as well. A measuring device built in accordance with the idea may constitute a tool for identifying the mechanical tyre characteristics, which might be then used inter alia as input data at simulation research on vehicles, e.g. for modelling the vehicle body vibrations or for analysing the energy absorption at vehicle motion.
Design of a cascade planar transformer for electrostatic precipitator use

The traditional high-voltage high-frequency transformer has a drawback of low power density due to the rigorous requirements of high voltage insulation. This paper proposes a new configuration for the magnetic core based on planar EE cores. The parallel connection of planar cores was adopted as a unit, and several units were cascaded to form the high-voltage transformer. The electrical potential distribution of the proposed transformer is more uniform than a traditional transformer, and enables a decrease in the insulation distances. The mechanical configuration of a laboratory prototype is discussed, as well as the electrical, parasitic, and thermal behaviors. A prototype transformer has been designed and built with the following characteristics: 30 kV output voltage, 30 kW output power, and 20 kHz inverting frequency. The transformer was tested and found to have an efficiency of better than 96%. Compared with traditional high-voltage transformers, this transformer has good thermal behavior, good line insulation properties and a high power density.
Analysis and experiments for high-efficiency class-F and inverse class-F power amplifiers

This paper presents analytic and experimental comparisons for high-efficiency class-F and inverse class-F amplifiers. The analytic formula of the efficiencies, output powers, dc power dissipations, and fundamental load impedances of both amplifiers are derived from the ideal current and voltage waveforms. Based on the formula, the performances are compared with a reasonable condition: fundamental output power levels of class-F and inverse class-F amplifiers are conditioned to be identical. The results show that the inverse class-F amplifier has better efficiency than that of class-F amplifiers as the on-resistance of the transistor increases. For experimental comparison, we have designed and implemented the class-F and inverse class-F amplifiers at I-GHz band using a GaAs MESFET and analyzed the measured performances. Experimental results shows 10% higher power-added efficiency of the inverse class-F amplifier than that of the class-F amplifier, which verifies the waveform analysis.
Pediatric T-Cell Acute Lymphoblastic Leukemia

T-cell acute lymphoblastic leukemia is identified in 10-25% of all newly diagnosed acute lymphoblastic leukemia's in children. The disease results from cytogenetic and molecular abnormalities which disrupt key oncogenic, tumor suppressor, and developmental pathways which control normal thymocyte development. Disruption of key pathways alter normal control of cell growth and proliferation, along with survival and differentiation. This paper provides an update on the cytogenetic and molecular basis of pediatric T-cell acute lymphoblastic leukemia.
An Alternative Coding Theorem for Posterior Matching via Extrinsic Jensen – Shannon Divergence

This paper considers the problem of coding over a discrete memoryless channel (DMC) with noiseless feedback. The paper provides a stochastic control view of a variable-length version of the posterior matching scheme which is analyzed via a recently proposed symmetrized divergence, termed Extrinsic Jensen–Shannon (EJS) divergence. In particular, under the variable-length posterior matching scheme, the EJS divergence can be lower bounded by the Shannon capacity of the DMC, which can be used for a relatively simple proof that the variablelength posterior matching scheme achieves capacity.
Trace Elements Status and Antioxidants Profile in Ill-thrift Buffalo Calves -

The goal of the present study was to evaluate some trace element concentrations and the activity of antioxidant systems in ill-thrift calves. A total number of (52) buffalo-calf was subjected to study. Out of them, (37) buffalo-calves had poor coat, poor general body condition score which constituted the ill-thrift group. The remained animals (15) were clinically healthy and kept as control group. Complete blood picture, trace elements profile, serum calcium , phosphorus & magnesium , blood urea nitrogen (BUN) , creatinine , some liver function parameters and total antioxidants capacity were evaluated. Results showed a significant reduction in the blood serum concentration of copper, cobalt, iron, selenium and zinc associated with normocytic normochromic anemia. Also a significant reduction in the activity of total antioxidants value was evident in ill-thrift calves. While levels of serum calcium , phosphorus & magnesium ,blood urea nitrogen , creatinine and liver function parameters showed non - significant changes. In conclusion, a state of sub-optimal growth (ill-thrift) in buffalo-calves was largely attributed to trace element deficiency, in particular copper, cobalt, iron, selenium and zinc deficiency that may cause reduction in the total antioxidant capacity, with a lower ability to reduce oxidative compounds.
Size-scaling of macromolecules and chemical energy content in the eukaryotic microalgae

The macromolecular composition and cell size of microalgae can influence their competitive interactions for nutrients and food quality for predators. Here we quantify the cell volume and dry weight based size-scaling of protein, lipid, carbohydrate and chemical energy content of eukaryotic microalgae from data extracted from the scientific literature. Across all the microalgae examined, cell size is an excellent predictor of macromolecular and chemical energy content with size-scaling exponents ranging from 0.8 to 0.93 for cell volume and 0.96 to 1.1 for dry weight. There are secondorder taxonomic differences in the size scaling of macromolecular and chemical energy content. Relative to the green algae and dinoflagellates, the diatoms have lower cell volume size-scaling exponents for protein, lipid and chemical energy content due to their larger increase in vacuole volume with increasing cell volume. The dinoflagellates have a lower size-scaling exponent for carbohydrate relative to the diatoms and green algae and the green algae have a relatively high size-scaling exponent for protein as compared to the diatoms. Differences in the size-scaling of macromolecular and chemical energy content across the diatoms, green algae and dinoflagellates appear to reflect fundamental differences in cellular architecture and growth and storage allocation strategies across these microalgal phyla.
Development of the Tourist Function Within Areas of Lower Silesian Landscape Parks

Abstract Subject and purpose of work: The aim of the study was to present the development of the tourist function in the areas of Lower Silesian landscape parks. The subject of the study were the communes associated with Lower Silesian landscape parks. Materials and methods: The study covered 59 communes of the Lower Silesia Voiovodeship where 12 landscape parks are located. In this research six indicators of the level of tourism development were listed - three in the field of conditions of tourism development and three in the field of tourist traffic. Results: A significant dependency between the surface area of a landscape park and the state of tourismoriented land development was established. It turned out that among the 59 surveyed communes in 14 of them there are no tourist accommodation facilities. Conclusions: Based on the conducted surveys, it was found that the highest level of tourist function development occurs in the communes associated with the following landscape parks: Śnieżnik, the Sudety Wałbrzyskie, the Owl Mountains, Książ and Bóbr Valley Landscape Park.
Extraction-preconcentration Mercury ion by Ghezeljeh montmorillonite nanoclay as a new native adsorbent from food and water samples

Ghezeljeh montmorillonite nanoclay or “Geleh-Sar-Shoor” (means head-washing clay) used as a native adsorbent to extraction-preconcentration mercury ions from a variety of real water and fish samples have been investigated in a batch system followed by atomic absorption spectroscopy (AAS) with vapor generation accessory (VGA) system. The clay was characterized by using FT-IR, SEM-EDS, XRF, XRD, CEC, Specific surface area and Zeta potential. The results of XRD, FT-IR, Zeta potential and CEC of the Ghezeljeh clay confirm that montmorillonite is the dominant mineral phase. On the basis of on SEM images, the distance between the layers is in nm level. The outcome of varying parameters and interfering ions were studied. Detection and quantification limits, preconcentration factor, and adsorption capacity were calculated. The Langmuir and Freundlich equations showed the finest fit to the equilibrium data. The adsorption procedure follows a pseudo-second-order reaction pattern. Calculation of ΔG0, ΔH0 and ΔS0 displayed that the nature of Hg(II) ions adsorption is endothermic and favorable at upper temperature.
IS A GOOD OFFENSE : C OUNTERING BLACK BOX ATTACKS BY PREDICTING SLIGHTLY WRONG LABELS

Black-Box attacks on machine learning models occur when an attacker, despite having no access to the inner workings of a model, can successfully craft an attack by means of model theft. The attacker will train an own substitute model that mimics the model to be attacked. The substitute can then be used to design attacks against the original model, for example by means of adversarial samples. We put ourselves in the shoes of the defender and present a method that can successfully avoid model theft by mounting a counter-attack. Specifically, to any incoming query, we slightly perturb our output label distribution in a way that makes substitute training infeasible. We demonstrate that the perturbation does not affect the ordinary use of our model, but results in an effective defense against attacks based on model theft.
Risk of Nitrate in Groundwaters of the United StatesA National Perspective

Nitrate contamination of groundwater occurs in predictable patterns, based on findings of the U.S. Geological Survey's (USGS) National Water Quality Assessment (NAWQA) Program. The NAWQA Program was begun in 1991 to describe the quality of the Nation's water resources, using nationally consistent methods. Variables affecting nitrate concentration in groundwater were grouped as “input” factors (population density and the amount of nitrogen contributed by fertilizer, manure, and atmospheric sources) and “aquifer vulnerability” factors (soil drainage characteristic and the ratio of woodland acres to cropland acres in agricultural areas) and compiled in a national map that shows patterns of risk for nitrate contamination of groundwater. Areas with high nitrogen input, well-drained soils, and low woodland to cropland ratio have the highest potential for contamination of shallow groundwater by nitrate. Groundwater nitrate data collected through 1992 from wells less than 100 ft deep generally verified the risk p.
Robustness Against Disturbances in Power Systems Under Frequency Constraints

The wide deployment of renewable generation and the gradual decrease in the overall system inertia make modern power grids more vulnerable to transient instabilities and unacceptable frequency fluctuations. Time-domain simulation-based assessment of the system robustness against uncertain and stochastic disturbances is extremely time-consuming. In this paper, we develop an alternative approach, which has its roots in the input–output stability analysis for Lur’e systems. Our approach consists of a mathematically rigorous characterization of the external disturbances that the power system is transiently stable and the frequency constraints are not violated. The derived certificate is efficiently constructed via convex optimization and is shown to be nonconservative for different IEEE test cases.
Geographic variation in temperature tolerance as an indicator of potential population 1 responses to climate change 2 3 Cascade

27 The temperature tolerances of individuals in geographically separated populations of a 28 single species can be used as indicators of each population’s potential to persist or become 29 extinct in response to climate change. We evaluated the population-level variation in temperature 30 tolerance in populations of several marine invertebrate taxa, including bryozoans, tunicates, 31 bivalves, and gastropods, separated by distances of <200 km to >5,000 km. We then combined 32 physiological thermotolerance data with current temperature data and climate change predictions 33 to predict which of these populations may be most vulnerable to future changes. In a trans34 continental comparison of four subtidal epibenthic species, we show that populations on the east 35 coast of the United States, which experienced higher habitat temperatures than those on the west 36 coast, had higher thermal tolerances but lived closer to individuals’ tolerance limits. Similarly, 37 temperature tolerances varied between western and eastern Atlantic populations of the mussel 38 Mytilus edulis; however, these differences only emerged after repeated exposures to high 39 temperatures. Furthermore, the less thermotolerant M. edulis population in the western Atlantic 40 was more susceptible to temperature increases, as evidenced by a recent range contraction. Thus, 41 for both the subtidal epibenthic and intertidal mussel species, we identified the western Atlantic 42 as a ‘hot spot’ of populations susceptible to climate change compared to those in the eastern 43 Pacific and eastern Atlantic, respectively. Finally, because current tolerances are not the sole 44 indicators of individuals’ abilities to cope with temperature increases, we also assessed the 45 possibility for acclimatization to facilitate the persistence of populations via the buffering of 46 temperature effects. We show that, for four populations of intertidal Littorina snail species in the 47 northwest Atlantic, most populations were able to overcome geographic differences in 48 temperature tolerance via acclimation. When acclimation capacity is low, the potential for 49

G R ] 2 2 O ct 2 01 8 SIMPLE GROUPS SEPARATED BY FINITENESS PROPERTIES

We show that for every positive integer n there exists a simple group that is of type Fn−1 but not of type Fn. For n ≥ 3 these groups are the first known examples of this kind. They also provide infinitely many quasi-isometry classes of finitely presented simple groups. The only previously known infinite family of such classes, due to Caprace– Rémy, consists of non-affine Kac–Moody groups over finite fields. Our examples arise from Röver–Nekrashevych groups, and contain free abelian groups of infinite rank.
Student Attendance Management System

DOI: 10.21276/sjet.2018. 6.2. 1 Abstract: Attendance management is important to every single organization; it can decide whether or not an organization such as educational institutions, public or private sectors will be successful in the future. Organizations will have to keep a track of people within the organization such as employees and students to maximize their performance. Managing student attendance during lecture periods has become a difficult challenge. The ability to compute the attendance percentage becomes a major task as manual computation produces errors, and wastes a lot of time. For the stated reason, an efficient Web-based application for attendance management system is designed to track student’s activity in the class. This application takes attendance electronically and the records of the attendance are storing in a database. The system design using the Model, View, and Controller (MVC) architecture, and implemented using the power of Laravel Framework. JavaScript is adding to the application to improve the use of the system. MySQL used for the Application Database. The system designed in a way that can differentiate the hours of theoretical and practical lessons since the rate of them is different for calculating the percentages of the students’ absence. Insertions, deletions, and changes of data in the system can do straightforward via the designed GUI without interacting with the tables. Different presentation of information is obtainable from the system. The test case of the system exposed that the system is working enormously and is ready to use to manage to attend students for any department of the University.

The Effect of Student Gender on Teacher Perceptions of Social , Emotional , and Behavioral Concerns

The Effect of Student Gender on Teacher Perceptions of Social, Emotional, and Behavioral Concerns Erin Williams Department of Counseling Psychology and Special Education, BYU Educational Specialist Students at risk for social, emotional and behavioral concerns (SEBC) are likely to experience a variety of negative outcomes if not identified and provided with appropriate interventions in a timely manner. Males tend to be identified more frequently than females for SEBC (Young, Sabbah, Young, Reiser, & Richardson, 2010), and there are many variables that may contribute to this disproportionate identification. This study specifically examined the influence of student gender on secondary education teachers’ referral decisions for students at risk for SEBC. This study additionally examined the influence of teachers’ prior referral experience, confidence in the mental health services available at their schools, perceived severity of problematic behaviors, and teacher gender as other variables potentially influencing teacher likelihood of referral. A sample of 229 secondary teachers was given vignettes about hypothetical male and female students with internalizing and externalizing concerns followed by a questionnaire. Findings from this study indicate that males with internalizing concerns were the most likely to be referred. Additionally, teachers’ prior referral experiences and their confidence in the mental health services available at their schools influenced their likelihood of making a referral. Results from this study can be used to inform and improve screening and identification processes in secondary settings.
