Abstract: The palm grove is a great ensemble of ph�nicicols gardens, as different from each other. Each orchard has its particular characteristics, as floristically that faunal. We are witnessing in previous decades to continual degradation of ecosystems "palm grove" whose main cause is anthropogenic. Our study would be to protect non-functional biotopes, based on biological indices. Thus, we generally distinguish maintained orchards, moderately maintained and non-maintained. The diagnosis of a biotope health status was assessed through its biocenotic composition. Significant differences both from the point of view floristic that faunistic were identified by comparing two ph�nicicol environments; one maintained grouping 33 floristic species and 45 faunistic species, other non-maintained with 13 plant species and 17 faunistic species. Floristic richness increased the number of trophic categories of which 11 are registered in maintained environment. We stipulate that the biocenosis present in an environment can be a source of information on the state of an ecosystem and its functioning. Keywords: Palm grove, fauna, flora, trophic regime, biological balance.

Abstract: Since the period of economic reforms in the Republic of Kazakhstan, we have not witnessed an effective system of chemical safety, and as a result, measures to ensure chemical safety are chaotic, fragmented and often not fully funded. Analysis of the current state of the Republic of Kazakhstan legislation shows that it lacks a comprehensive approach towards the legality of chemical safety, and only a few rules, sometimes scattered, regulate the grounds and procedures for the use of various kinds of chemical substances and preparations. In view of the many aspects of chemical safety to ensure it is interdisciplinary, including various types of law regulation nature. In this context, the most relevant are the investigations of chemical safety as a matter of civil regulation, the study of concepts and certain types of civil legal means to ensure chemical safety. Therefore, the aim of the research is develop the conceptual foundations of the civil-law provision of chemical safety of the Republic of Kazakhstan and offer proposals, suggestions to improve legislation in this area and its practical application. Scientific novelty of this paper is complex research maintenance of chemical safety in the conditions of the state independence and economy.

Abstract: This case study aimed to find out in-service Life Sciences teachers understanding of core concepts of the nature of science (NOS) in the context of Biological Evolution and Religion for teaching. Teachers understanding of NOS is crucial for their understanding and acceptance of Evolution and for their effective teaching of topics such as Evolution that underpins Life Sciences. Qualitative data was obtained from VNOS-C questionnaires and semi-structured individual interviews from three high-school teachers. The data from the two sources were coded into the seven NOS predetermined broad categories. Inductive analysis was then performed to obtain further distinct ways of understanding each NOS category. The results revealed that although all three teachers understood some of the concepts of NOS, they could not adequately integrate content knowledge of Evolution into all seven categories of NOS to the same extent in planning to teach. Of significance, they were not necessarily influenced by scientific understandings of NOS conceptions but influenced by a particular set of personal beliefs incorporating religion and everyday experiences. The study has implications of the significance of teachers beliefs for the enhanced development of in-service and pre-service teachers in the teaching of NOS in Evolution in Life Sciences.

Abstract: Striostrea prismatica (Gray, 1825) represents one of the most popular and artisanal fisheries in the rocky coast, but now cultivation of stone oyster in a call channel for shrimp is a new method to calculate their growth, condition index and survival. A total of 1 500 juveniles were seeded with a length of 19.1 ± 3.2 mm, width of 16.2 ± 3.19 mm, height of 3.97 ± 1.36 mm and 1.0 ± 0.54 g weight. They were placed in 70-60 organisms Nestier type baskets, seeds were collected from the oyster shells which were discarded by fishermen. Temperature was the most important variable, combined with salinity and food availability in seasons, coupled with low concentrations of seston which had a negative correlation with growth and consistent with the increase in the condition index and rates high growth. Survival rate was 73.03%. The model parameters von Bertalanffy growth are L∞ = 142.63; k = 0.0489 and t0 = -2.198. At the end, height and average weight was 73.53 ± 15.38 mm and 31.56 ± 17.17 g, which although is less than the minimum catch size proposed in NOM 90 mm, the results show that the fattening of juvenile oyster is appropriate for the fishery resource, applicable and effective for strategy management.

Abstract: Code-mixing and code-switching in bilingual countries including Pakistan, are very common phenomena. We can observe this in media, and in our daily use of language. The aim of this research is to highlight the case of code mixing of English with Urdu in Pakistan which has actually replaced the words from Urdu, and the vocabulary from Urdu is endangered due to the over-use of certain English words. For this study the data was collected from different resources i.e. through media news channels, F.M Radio, newspapers, questionnaires, and interviews. This research might help in spreading awareness among the linguists, language teachers, the common man, and the authorities involved in making language policies. The study highlights a very important socio-linguistic phenomenon that due to the excessive use of English words Urdu might loose a considerable number of vocabulary items from Urdu forever.

Abstract: When facing a natural disaster of great magnitude and social significance, the population needs to reduce its vulnerability through timely, truthful, and contextualized information. In this context, media’s role is tested, since they have to face scarcity of data, lack of coordination between different sectors of a country and breaks in their routine. This paper analyzes, describes and compares the coverage made in two Latinamerican countries, Guatemala and Chile, by the three most-watched broadcast television newscasts of the earthquakes suffered respectively in 2012 and 2010. Based on a quantitative content analysis, it concludes that, despite the differences of contexts, certain professional standards, as the proper selection of sources, respect for ethical standards and the use of different frames are deficient in the television coverage of the affected places as a result of ethical and informative challenges faced by editors and journalists during the coverage of major disasters. This work analyzes specifically the work done in television, because it is one of the main sources of data during natural disasters, especially in Latin America, with a great ability to convene people and it is one of the media that needs higher quality and quantity of human and technical resources to broadcast content.

Abstract: It is known that sialolithiasis is the most prevalent disease among salivary pathology. Based on different authors, it accounts for 20.5-78% of all cases. Even early detection of this disease doesn't guarantee the patient a complete recovery as the therapy of sialolithiasis, as a rule, is limited to surgical intervention (removal of the concrement or the salivary gland itself) without follow up impact on to the organ or the whole body. Quite frequently chronic inflammation of dystrophic process in the salivary gland after numerous cases of recurrence, becomes in indication to its removal . In many cases such outcome could have been prevented by administering adequate treatment, targeted at prevention of recurrence of salivary stone formation. Management of these issues formed the foundation of the work, defining is goals and objectives. Concrements mostly developed in submandibular (90-95%) and most rarely in parotis (5-8%). They were tested to establish chemical composition and the structure of such concrements in salivary glands, with the objective of identification of their development mechanisms. The total of 11 stones were removed from Wharton ducts of patients with sialolithiasis. Testing salivary stones yielded in following results: the major part of salivary stones (80%) consists of apatite and the remaining (20%) � of apatite and vitlocite. The prevention approach based on the mineral composition of stones had significantly reduced the formation of oxalatecalcium stones over three years. Nevertheless, it is desirable to continues such studies to confirms the efficiency of prevention of sialolithiasis by such method of treatment and collect more information on principles of action of such method.

Abstract: One benefit of vegetation is litter produced that play an important role in improving and sustaining the soil quality. In addition, the litter decomposition process also produces nutrients that improve soil fertility and can be used by plants. The purpose of this study was to evaluate the production of litter and the contribution of nutrients from litter of five dominant tree species in the Sub-watershed Tondano, Minahasa, North Sulawesi. The study was conducted in October 2010 - May 2011. Litter production is measured using the net litter container that is placed under the canopy of the five tree species, with each tree 15 observations and repeated three times. Litter collection is done every day. Litter is analyzed in the laboratory of the University of Sam Ratulangi, Manado, to determine content of macronutrients and micronutrients. The results showed that litter in the wet season were produced by Elmerellia celebica that is equal to 16.11 Mg ha-1 year-1. The dominant macronutrients of litter is C. The C content is highest in the litter of Eugenia aromaticum, that is equal to 50.24%. The dominant micronutrients are Fe and Mn. The highest content of Fe and Mn are in litter of Elmerellia celebica, which amounted to 416.4 mg kg-1 and 132.5 mg kg-1, respectively.

Abstract: An exploration into youthful African masculinities by examining the role of gender in the spread of HIV/ AIDS provides insights into the pliable nature of the heterosexual matrix. An empowering methodology was employed to enable young African men to serve as co-researchers, to explore the nexus between HIV/AIDS and sexualities. The co-researchers engaged in a photovoice activity, interviews and reflective journal writing, and through these activities, they ruptured pre-established ideas about hegemony, young Africans and masculinities. Analytical frames of dominant, complicit and resistant masculinities were used to chart the micromovements of young African men as they engaged in doing African masculinities in diverse ways, and illuminated spaces for transformative social action within the context of HIV/AIDS.

Abstract: Since personality disorders, including narcissistic disorder are on the rise, this disorder may have a negative impact on the various spheres of life, such as employment, education, family and marital status. Therefore, this study attempts to evaluate the effect of narcissistic disorder on marital discontent. The research is descriptive and correlational; 20 couples cooperated in the study. In order to determine the amount of narcissism, Mz narcissistic questionnaire NPI16 was used; also to determine the amount of marital satisfaction, ENRICH47 marital satisfaction questionnaire was used. Bivariate (simple) regression correlation analysis was used for the analysis of data. The effect of couple's narcissistic disorder on marital discontent f = 62/53 was significant (P <0/0001); it explains the discontent of couples with respect to the percentage of variance. In other words, narcissistic disorder of couples has a significant negative impact on marital satisfaction; dissatisfaction increases with an increase in narcissism and vice versa. Conclusion: The results suggest that there is a negative and significant relationship between narcissistic personality disorder and marital satisfaction. Thus, it is suggested that managers and directors of mental health diagnose and treat narcissistic people to achieve marital satisfaction. Keywords: narcissism, marital satisfaction

Abstract: Culture is a very valuable part of society. The study of a foreign language not only teaches the language itself, but it also introduces information on another culture, moral values and attitudes. Improving the quality of foreign language education is important. Demanding course content, low proficiency and foreign language learning anxiety discourage students from learning. Difficulty in communicating in the target language reduces their self-confidence. The use of drama could be one of the possible means to increase motivation and self-esteem and to improve foreign language skills and cultural awareness. The authors share their experience in using drama in extracurricular activities with students studying English as a foreign language at the Institute of Non-Destructive Testing, National Research Tomsk Polytechnic University.

Abstract: This paper is based on a study which explored the use of visual reasoning by successful mathematics teachers. Nationally and internationally, mathematicians have been searching for ways to improve on the ways that learners understand mathematics. Contrary to the view that mathematics is a set of formal rules that must be presented in a sequential manner, mathematics is a discourse which requires a multidimensional approach in its teaching. Visual reasoning is an indispensable tool in the teaching of mathematics. Despite the poor results in mathematics, there are still groups of very successful teachers who, despite all odds, are achieving success in their classrooms. This study examined the teaching of a group of successful mathematics teachers. The study showed a strong tendency of the participants to engage with visual reasoning in their classrooms.

Abstract: The paper identifies the level and nature of differentiated instruction (DI) implementation in Indonesian primary schools. Teachers reported their level of DI adoption and reacted to five vignettes reflecting key dimensions of DI. Research data revealed overall DI implementation is significantly below the mastery learning benchmark (80%). Nevertheless, teachers feel they are able to cope with student diversity and have basic ideas about DI implementation. Research implications point at educational policies to invest in initial teacher training and professional development, next to a need for parent involvement. Future research could centre on studying actual teacher behavior in classrooms, next to experimenting with particular DI-strategies.

Mean initial body weight and length were: sub-adults 117.7±39.2 g with 18.7±2.5 cm, juveniles 79.0 ±32.2 g with 16.8±2.3 cm, and small juveniles 8.7±4.9 g with 7.7±1.5 cm; The final weight and length of sub-adults were 556.8±132.g and 32.6±2.9 cm, juveniles 477.4±134.5 g and 31.1±3.1 cm, and sub-juveniles 230.9±81.4 g and 24.1±2.9 cm. Absolute growth and specific growth rate reached for sub-adults was 1.8±1.4 g/day and 0.7±0.5 %/day, for juveniles 1.6±0.9 g/day and 0.8±0.5%/day, and for small juveniles 0.9±0.8 g/day and 1.4±0.7 %/day. Weight gain was of 445.5±93.2 g, 398.0±102.3 g, and 222±76.5 g for the three sizes stocked. Feed conversion factor was 1.7±0.4, 1.5±0.4, and 1.0±0.4 for the three stocks. Conditions factor was of 1.6±0.2 for adults, 1.7±0.2 for small juveniles. Overall survival rate was 98.9%. Daily temperature ranged from 3 to19°C, dissolved oxygen was from 5 to 6.4 mg/L and salinity from 32 to 35‰. The stocked densities had no adverse effect on growth and survival. This species has potential for aquaculture due to its growth rates and it is resistant to handling and confinement.

Abstract: Modern organizations provide their needed goods and primary materials from other organizations in other countries and the only resource which can not be exchanged in its ideal form easily is human force so that it can be said the most important competitive capital of a country is efficient or standard human force. The main purpose of current research is to study the relationship of personality and motivational traits of managers with evaluation of their success rate in non-governmental organization of Tehran city. The population studied in this research includes the managers of non-governmental organization of Tehran city that are 400 persons and 120 persons were selected as the statistical population sample by using of statistical orders. The required information were collected by using of library and field methods (questionnaire tool). In order to analyze the data, spss software was used. The analysis of the research findings indicated that there is meaningful relationship between neuroticism and occupational success of managers in non-governmental organizations of Tehran city, and the relationship between two variables is reversed. Also there is positive and meaningful relationship between extroversion and occupational success of managers, sense of duty and occupational success of managers, compliance and occupational success of managers, openness to the experiences and occupational success of managers in non-governmental organizations of Tehran city.

Abstract: One problem of internet telephone networks which is expected to create some problems such as email spams for telephone systems is SPITs (Spam Over Internet Telephone). The detection of SPITs in internet telephone networks must be done immediately, irrespective of content and prior to the initiation of a session. On the other hands, process of disruptive contacts is exactly same as the process of healthy contacts which this can make the detection of SPITs challenging. Therefore, by introducing a new method which concentrates on users� behavior and a look at susceptibilities existing in Voice over Internet Protocol (VOIP) which can lead to SPITs, present paper attempts to introduce an anti-SPIT system which is able to detect simultaneous disruptive contacts in signaling stage. Taking into account the susceptibilities leading to SPITs, the proposed system identifies users� suspicious behaviors, and following examining contact characteristics, using a response/challenge method allow only entrance of users who have made a normal contact. The evaluation of the proposed method is done using its simulations, and the resultant detection rate and incorrect alarm rate indicate the success of this method in preventing the entrance of SPITs into a network.
