EFFECT OF GAME INSTRUCTIONAL APPROACH ON CHEMISTRY STUDENTS’ ACHIEVEMENT AND RETENTION IN PERIODICITY

This paper investigated the effect of games teaching approach on chemistry students’ achievement and retention in periodicity. The research designed employed was pretest -post test control quasi experimental design. Multi-stage random sampling technique was used to select 96 students who participated in the study. Periodicity Achievement Test (PAT), used as Pre-Test (PREPAT), Post-Test (POSTPAT), and Post-Post-Test (PPPAT) was developed by the researcher and validated by experts. The reliability coefficient of the instrument obtained using spearman-brown prophecy formula was 0.77. Five hypotheses were formulated and tested at 0.5 level of significance. The pretest was administered to subjects in both groups to measure their knowledge in periodicity. The control group was taught periodicity for four weeks using only the conventional method while the experimental group was also taught periodicity for four weeks with games method. POSTPAT was administered to all the subjects at the end of the fourth week. Two weeks after the administration of POSTPAT, the PPPAT was administered to both groups. The results show that the students taught periodicity using game method achieve and retain better than those taught with conventional method. It was also discovered that gender has no influence on the achievement and retention of those exposed to treatment.
THE IMPACT OF SALINITY WATER ON GROWTH AND YIELD OF TWO OATS CULTIVARS (AVENA SATIVA L.)

A field experiment was conducted in one of the farms in Babylon governorate during winter season. (2015-16) and (2016-2017) to know the effect of salinity water in growth and yield of three varieties of oats. were used. RCBD distribution with (split-plot design) with three replication. The result showed a significant effect of salt water irrigation all studied qualities. Where decreased values of studied characteristics by increasing salinity water more than 3ds.m -1 and showed no significant differences with comparative coefficient (irrigation by river water) in all studied characteristics. While salinity level 9ds.m -1 give the least average number of Tillers (457,422) per/m -2 and number of panicles (376, 355) per/m and number of grain in panicle (28.54 and25.97) per/m,waght of 1000 grain (26.77, 26.48) gm, grain yield (3.96, 3.71) ton/h, biological yield (17.53, 16.43) ton/h, average of plant growth (12.30, 11.55) gm.m -2 , harvest Index (22.52, 23.08)% both of season. The result of statistical analysis showed a significant differences between genotypes, where plant gave varieties ALshafa and Hamel high average for number of tillers, biological yield, plant growth yield and grin yield both of season . thus we conclude salt stress is a negative effect on the stage of plant growth which is reflected negatively on grin and its components.
Task-specific performance fatigability and the bilateral deficit during isokinetic leg extensions

Objectives: The purpose of the present study was to compare the fatigue-induced changes in performance fatigability, bilateral deficit, and patterns of responses for the electromyographic (EMG) and mechanomyographic (MMG) amplitude (AMP) and mean power frequency (MPF), during unilateral and bilateral maximal, fatiguing leg extensions. Methods: Nine men (Mean±SD; age =21.9±2.4 yrs; height =181.8±11.9 cm; body mass =85.8±6.2 kg) volunteered to perform 50 consecutive maximal, bilateral (BL), unilateral dominant (DL), and unilateral non-dominant (NL) isokinetic leg extensions at 180°·s-1, on 3 separate days. Electromyographic and MMG signals from both vastus lateralis (VL) muscles were recorded. Repeated measures ANOVAs were utilized to examine mean differences in normalized force, EMG AMP, EMG MPF, MMG AMP, MMG MPF and the bilateral deficit. Results: The results demonstrated a Condition × Repetition interaction for normalized force (p=0.004, η2p=0.222) and EMG MPF (p=0.034, η2p=0.214) and main effects for Repetition for EMG AMP (p=0.019, η2p=0.231), MMG AMP (p<0.001, η2p=0.8550), MMG MPF (p=0.009, η2p=0.252), and the bilateral deficit (p<0.001, η2p=0.366). Conclusions: The findings demonstrated less performance fatigability during the BL than the unilateral tasks, likely due to a reduced relative intensity via interhemispheric inhibition that attenuated the development of excitation-contraction coupling failure during the BL task.
Food and Feeding Habitats of the Mullet Fish, Liza abu from Musa Estuary, Persian Gulf

Liza abu is very important in term of economically and ecologically in the estuaries around the Persian Gulf. Studies on the feeding ecology of Liza abu are very important for our better understanding of the biology and the ecological role of this fish for assess reserves and species conservation. The influence of sex and season on the feeding habit of Liza abu from Musa estuary in Khozestan province, was examined. The first, the biometry features were measured then the stomach of each sample was surveyed. Ten different groups of prey were identified, belonging, in order of abundance, to detritus, organic matter, seaweed, Chlorophyceae, Myxophyceae, Bacillariophyceae, Copepods, Insect larvae, Nematodes and other. The comparison indicated that there was striking difference between the contents of male and female stomachs. There were significant differences in the preference for food items in the different season (P<0.05).
Effects of reaction conditions on laccase-catalyzed α-naphthol polymerization

Enzymatic oxidative polymerization of α-naphthol was carried out batch-wise with the laccase enzyme, produced by Trametes versicolor (ATCC 200801). The polymerization reaction was conducted in a closed, temperature controlled system containing acetone (solvent) and sodium acetate buffer for pH control. The effects of the organic solvent (acetone) composition, monomer (α-naphthol) and enzyme concentrations, buffer pH and temperature on the polymerization rate were investigated with respect to initial reaction conditions and depletion rate of dissolved oxygen. The optimum acetone composition, pH, monomer, dissolved oxygen and enzyme concentrations were determined as 50% (v/v), 5, 3409 gm−3, 20.3 gm−3 and 0.173 U cm−3, respectively; these values provided the most desirable conditions for initial reaction rate. Temperature rise supported the rate increase up to 37 °C, after which the rate tended to be stable due to a drop in dissolved oxygen concentration. The product polymer, poly(α-naphthol), with an average molecular weight of 4920 Da was soluble in common organic solvents. © 2000 Society of Chemical Industry
Monopolistic Screening under Narrow Framing: Applications to Product and Credit Markets

We extend the standard model of monopolistic screening to allow for some consumers who engage in narrow framing, a prominent behavioral bias. Narrow framing generates a bias toward high quality-price ratios, which induces even high-type consumers to choose the menu that targets low-type consumers. To strategically account for narrow framing, when the monopolist induces the high-type consumers to stay with the more expensive menu, there arises a downward quality distortion even at the top and a smaller downward distortion at the bottom. We also apply our analysis to optimal loan contracts to screen heterogeneous borrowers with different default risks.
POSSIBLE SOCIAL, ECONOMIC AND SECURITY-POLITICAL CAUSES OF TERRORISM: VIEW OF EXPERTS FROM THE CZECH REPUBLIC

An integral part of the issue of terrorism is not only the consequences of committed terrorist acts which lead to subsequent security measures but also the causes of terrorist activities which determine the reasons why people are motivated for these activities. The paper focuses on the social factors (social inequality in society, citizen’s standards of living, level of citizens education, religion), economic factors (economic performance of state, unemployment, inflation) and security-political factors (corruption, criminality, political instability, government ineffectiveness, war conflicts) which potentially generate future terrorist activities. The main target is to analyze opinions of 98 Czech respondents on importance of individual factors. Experts from military, police and academic institutions in the Czech Republic were selected as respondents for the questionnaire. Based on this analysis we made summarized statement about possible causes of terrorism. According the respondents, securitypolitical area is the most important (especially current national and international war conflict), followed by social area (Islam religion) and economic area (youth and adult unemployment).
Effects of oil enriched diets on growth, feed conversion ratio and fatty acid content of Nile tilapia (Oreochromis niloticus) in biofloc system

The effect of oil enriched diets to increase omega-3 fatty acids in the flesh of Nile tilapia (Oreochromis niloticus) by biofloc technology (BFT) system cultivation was investigated. Six feed diets containing 30% protein were added with different types of oil; control diet added with soybean oil, feed diet added with fish oil (FO), feed diet added with fish oil and soybean oil 1:1 (FO:SO), feed diet added with lard oil (LO), feed diet added with lard oil and soybean oil 1:1 (LO:SO) and feed diet added with fish oil and lard oil 1:1 (FO:LO). Each treatment was done in triplicate. Nile tilapia (initial weight 30±1.20 g) larvae were cultured in glass tanks and reared for 8 weeks. Tilapia fed with FO diet showed highest growth and weight gain (62.7±0.18 g) (p>0.05). However, there were no differences in the survival rate (95-97%) and feed conversion ratio in every treatment (1.41.5) (p>0.05). The fatty acids profile of flesh fed with 6 oil supplemented diets was studied. Fatty acid composition of FO was highest in total omega-3 (21.49%), followed by LO:SO (11.28%). FO treatment had the highest total omega-6 (52.78%), followed by control treatment (46.94%). This study demonstrated the efficacy of omega-3 fatty acids supplementation of fish fed in biofloc system that could be meet commercially valuable in the future.
The Subsistence Economy of Qela Gap; Lurestan, Iran: From the Late Neolithic to the Iron Age

Tepe Qela Gap (also known as Ghala Gap ) in Azna: Lurestan, was excavated in 2009 aiming to establish the chronological sequence for the Azna Plain located eastern of Central Zagros, which had been scarcely studied archaeologically until now. Considering the ecological diversity surrounding the plain, Tepe Qela Gap seems to have been an ideal place for the settlement of permanent villages but could also be suitable for nomadic and seminomadic people. The archaeozoological study of a large faunal assemblage, approximately 6500 items from this site, has provided evidence on the evolution of the subsistence economy of the site during various periods of occupation. The faunal spectra of Qela Gap from different periods, indicates that domesticated sheep/goat and cattle were the major source of animal resources. Among these domesticates it should be noted that cattle ratios are important and together with evidences of kill off patterns and osteological pathologies, we can hypothesise that these animals were used not only for food but also as draught animals, most probably, used for agricultural activities. This is a feature especially visible during the Bronze Age. The wild species, although not abundant (6%), were also part of the subsistence economy. Remains of wild sheep (Ovis orientalis), red deer (Cervus elaphus) or persian fallow deer (Dama mesopotamica), boar (Sus scrofa) and gazelle (Gazella subgutturosa) have been found and indicate that different ecosystems were exploited. Another important feature of the Qela Gap fauna is the discovery of a horse (Equus caballus) bone within the Neolithic Levels. In parallel to the archaeozoological analysis, the archaeobotanical studies are on-going and will provide a more complete picture of the subsistence economy of the site during the 5000 years of occupation.
Similarities and Dissimilarities Between Child and Adult L 2 Language Acquisition From a Morphological Perspective

Under the assumption that acquiring a second language (L2) is intrinsically different from acquiring a first language (L1), all L2 learners, both children and adults, are expected to exhibit a similar acquisitional pattern, which differs from children acquiring an L1. This paper discusses the expected similarities and differences between child and adult L2 learners based on the deliberation of a morphological phenomenon.
Removal of Phenol from Water by Adsorption Using Zeolites

Adsorption has been investigated to remove phenol from an aqueous solution (concentration range from 0.1 to 1.6 g·L-1). Zeolites were used as adsorbents, and adsorption properties were compared to those of an activated carbon. To adsorb phenol selectively from water, adsorbents must be hydrophobic, i.e., zeolites owning a high Si/Al ratio. Thus, purely siliceous BEA zeolite (Si/Al = ∞) was used with success; the adsorption capacity was slightly higher at low phenol concentration (≤1.6 g·L-1) than the one of activated carbon (surface area close to 1150 m2·g-1). Furthermore, siliceous BEA zeolite appears as an efficient adsorbent able to be easily regenerated while keeping these initial properties.
Building an Ontology structure in deep learning model of recommender systems

Nowadays, most of developments in deep learning have been proved extremely beneficial for several Medication and Healthcare Tasks. Most of re-searches in deep learning are focus on figuring out the structured specialities under the data and creating the models to learn how to demonstrate them from raw and unfiltered data. And now, Ontology is a popular vocabulary structure to describe data meaning. In this article, we mention to the possibility of creating Ontology structure of training data in Deep learning Model. More precisely in this paper we summarize the advances in both deep learning and semantic data mining for Health And Medical Sciences Task in recently. We illustrate how learning model with ontology-based deep learning that can extract better data representations to provide more information for the learning process. Using the framework of pattern structures and Formal Concept Analysis algorithms to build a pattern concept lattice in deep learning model. Finally, we present our intentions in building a diagnostic application that uses Ontology-based deep learning.
The study of fetal weight and various fetal parameters during the late gestational period (27-40 weeks) in the Gujarati population by autopsy method

DOI: 10.5455/ijmsph.2020. 07106202010122020 importance to monitor the adequate fetal growth. The clinical use of ultrasonography in obstetrics was introduced by Ian Donald in 1958 which has become gold standard now for the dating of the pregnancy during all three trimesters. [1] Although it is said to be not a reliable method for the age estimation. [1] Obstetricians use weight as well as various morphometric parameters to calculate the age of the fetus such as crown to rump length (CRL), crown to heel length (CHL), and head circumference (HC).

Improving FIFA Free Kicks Player Agent Performance through Object Detection Techniques

—Video games stand out as an important case study in the Machine Learning and Computer Vision based researches for the following reasons: in addition to presenting challenging technical difﬁculties, they have a high impact on the current economic scenario. Although several of these researches use Deep Reinforcement Learning (DRL) algorithms as a learning approach, few of them use Object Detection Techniques (ODTs) to improve their state representation strategy. Motivated by these arguments, the present paper proposes two DRL + ODT based agents to cope with free kicks in the FIFA digital game. The main contributions here are: to test the performance of the enhanced ODT version named MobileNetV2 in dynamic environments; and improving the performance of the free kicks agents through the inclusion of the barrier element as a new object to be detected by MobileNetV2 ODT. The results conﬁrm the efﬁciency of MobileNetV2 in terms of the performance of the agents in dynamic environments.
Opacity of Networked Supervisory Control Systems Over Insecure Communication Channels

In this article, we investigate security and privacy issues in networked supervisory control systems over multiple channel networks. We consider a networked discrete-event system controlled by a supervisor that receives information from sensors and sends control decisions to actuators via observation channels and control channels, respectively. The security problem is studied for the scenario where some of the communication channels are insecure in the sense there exists a passive intruder (eavesdropper) that can access the information-flow in those insecure communication channels. We adopt the concept of opacity, an information flow security property, to characterize the security status of the supervisory control system. Specifically, we assume that the system has a secret and the system is said to be opaque if the intruder can never determine the secret of the system unambiguously based on the information-flow in the insecure channels. We consider the notions of current-state opacity, $K$-step opacity, and infinite-step opacity in the networked control setting. New network observers are proposed to estimate the state of the system with two-side incomparable channel information. We show that the opacity verification problems for the networked setting can be effectively solved using the proposed network observers.
Corporate Social Responsibility and bank capital adequacy

We examine the relationship between superior corporate social responsibility (CSR) and firm value, and CSR and capital adequacy for global banking industry firms for the period after the Global Financial Crisis. We find a positive relationship both between CSR and firm value, and between CSR and capital adequacy. Because superior CSR is associated with higher trust, better corporate reputation, and relationships with regulators, investors, and depositors, we ascribe our results to superior CSR banks being able to raise capital more easily, enabling them to maintain appropriate levels of capital that lead to higher firm values. We provide evidence consistent with this channel.
Evaluation of knowledge, attitude and practices of university students towards rational use of medicines

Background: Rational use of medicines (RUM) requires that individuals get the correct medication, in the accurate dose, for an adequate period and at the lowest cost. Irrational drug use has a negative impact both on health and the economy. Hence, this study aimed to assess the knowledge, attitude and practice for the rational use of medicine among university students in a public university in Malaysia. Methods: The cross-sectional descriptive study was piloted using a validated self-administered questionnaire to collect the needed data from students. All data were checked for completeness and accuracy and then coded for analysis. Descriptive statistics were used to present the data on demographic characteristics, knowledge, attitudes, and practice towards RUM. The influence of demographic characteristics on knowledge and attitude was tested using Fishers exact tests or Chi-square, Mann-Whitney test and Kruskal-Wallis test wherever appropriate considering a p value <0.05 as statistically significant. Results: Overall, 418 questionnaires were distributed to university students. The results of the study revealed that 54.9% of the students had a moderate; 38.2% had poor and only 6.9% had a good level of knowledge towards RUM. A high percentage (64.4%) knew that all medicines have side effects; however, (66.4%) thought that multivitamins are safe without any side effect. Half of the respondents could not differentiate a medicine by either its generic or brand name. Most of the respondents (77.9%) incorrectly stop taking medicines when they feel better. Respondents (67.9%) purchased medications only upon physicians' prescriptions. Conclusion: The ANALYSIS 24(106), November December, 2020 Medical Science ISSN 2321–7359 EISSN 2321–7367
Giang Binh Tran Combining of text-based semantics and vision-based semantics

Learning and representing semantics is one of the most important tasks that significantly contribute to some growing areas, as successful stories in the recent survey of Turney and Pantel (2010). In this thesis, we present an innovative (and first) framework for creating a multimodal distributional semantic model from state of the art text-and image-based semantic models. We evaluate this multimodal semantic model on simulating similarity judgements, concept clustering and the newly introduced BLESS benchmark. We also propose an effective algorithm, namely Parameter Estimation, to integrate textand imagebased features in order to have a robust multimodal system. By experiments, we show that our technique is very promising. Across all experiments, our best multimodal model claims the first position. By relatively comparing with other text-based models, we are justified to affirm that our model can stay in the top line with other state of the art models. We explore various types of visual features including SIFT and other color SIFT channels in order to have preliminary insights about how computer-vision techniques should be applied in the natural language processing domain. Importantly, in this thesis, we show evidences that adding visual features (as the perceptual information coming from images) is comparable (and possibly better) than adding further text features to the advanced text-based model; and more interestingly, the visual features can capture the semantic characteristics of (especially concrete) concepts and they are complementary with respect to the characteristics captured by textual features.
Tuning Nanoparticle Properties—The X‐ray Absorption Spectroscopic Point of View

Abstract A key requirement for the realization of nanotechnology's technological potential is the ability to produce nanoparticles with well defined, tailored properties in a cheap and reproducible way. For numerous materials, wet‐chemical approaches with scale‐up potential exist which allow to synthesize stabilized particles of a given size, but it turns out that control of these two parameters is not sufficient to control particle properties completely. This suggests that the exact way of stabilization and the course of the synthesis may exert notable influence on particle properties. This work reviews experimental evidence for such influence with a focus on the perspective of x‐ray absorption spectroscopy. The thus obtained results indicate that not only size‐dependent phase transitions, but also chemical interaction between the core of the nanoparticle and its surfactant molecules are responsible for the observed spectral changes, which can be explained when constructing detailed models of core‐surfactant interaction. Also, it is observed that the surfactant can influence the course of the synthesis of a given nanoparticle notably. All of these results suggest a possibility to refine the finetuning of particle properties by exerting influence on synthesis and surface‐matrix interaction by suitable choice of surfactant molecules.
Many‐electron explicitly correlated Gaussian functions. II. Ground state of the helium molecular ion He+2

Explicitly correlated Gaussian functions have been used to compute variationally the Born–Oppenheimer (B–O) potential energy curve for the ground 2Σ+u state of He+2. The energy values are much lower than all previously reported over the whole range of the internuclear distance R. The strict lower bound for the binding energy De amounts to 2.4730 eV and the true value (within the B–O approximation) is estimated to be 2.4742±0.0006 eV.
