Optimization Of Diving With “Nitrox” Over-Oxygenated Breathing Mixtures, To Depths Of 15 ÷ 50 Metres
Authors: Degeratu Mircea , Rus Simona , Ion Ana 
Published: November 2015

Abstract
The efficiency of diving activities carried out by divers should be increased. Improving the efficiency of interventions made with divers at depths greater than 15m has brought into focus the problem of increasing underwater working time by using over-oxygenated synthetic breathing mixtures in order to optimize the relation between working time and duration of decompression. The “NITROX” binary mixture best meets the requirements of diving at depths within the range of 15 to 50 meters. NITROX is used for depths in the range of 15 to 50 m. When this mixture is used, the decompression time shortens and the respiratory resistance decreases. Therefore, the use of NITROX leads to an improvement in diving efficiency, by increasing underwater working time, and by reducing the decompression time.

Authors: Andronie Mihai 
Published: November 2015

Abstract
All types of economic institutions have the potential to gather large data volumes related to the activities they are performing. Usually it is possible for the management of such an institution to take advantage of the volume of data that is available and to take informed decisions, based on the knowledge gathered over extended periods of time, instead of taking decisions only by the experience of the management team. In such a way, success on the long term can be attained and the institutions can further improve the quality of their offer to the customers.
Decision support data is usually stored in specialized databases or data warehouses that are hosted on specialized servers. These servers must be secured against all types of events that can impede their correct functioning.
The present paper is focused on modelling and describing a work frame with the requirements that ensure the security of data used by economic organizations. Among these requirements can be mentioned: the existence of business continuation and disaster recovery plans, the existence of escalation paths for solving problems in a timely manner, preserving the uniformity of data in order to make analysis processes more straightforward, in a shorter period of time.

Authors: Virca Ioan , Dascălu Viorel , Grigoraş Constantin 
Published: November 2015

Abstract
The current maintenance system, preventively planned and applied to the military equipment according to the necessities, involves the rigorous execution of maintenance operations, which results in high costs and volume of work. These causes generally determine the formality of planned repairs and maintenance, with detrimental effects for the availability of vehicles. Moreover, the constructive-functional level of the current technical systems leads to the reorientation of adopting maintenance strategies that correspond to the availability level of the constructive kits to computerized diagnosis operations, such as the maintenance based on operational reliability. For some types of vehicles, the periodical technical inspection, besides allowing for regular traffic on public roads, can offer significant data for the managerial and technical implementation of the maintenance based on operational reliability within the military units. The paper aims at offering viable and efficient solutions for executing maintenance activities and for making vehicles available by turning to good account the data resulting from the technical diagnosis process, correlated with an optimal management of maintenance.

Published: November 2015

Abstract
The business-life related competition established in modern communities has also brought about some other problems. The attacks and intimidation attempts have introduced the term of “mobbing” which is defined as regular and continuous psychological violence faced by people always trying to produce and win from those who they work with. The term of “mobbing” has recently become a popular academic issue which has been sophisticatedly handled in relevant literature. Mobbing is defined as the act of continuous and systematic intimidation purposefully performed by either some employees or employers on some employees through emotional violence. As mobbing is considered to be significant for both corporate and employee, the starting point of this study was to investigate how mobbing acts are reflected on newspapers as they are mass communication means. One of the most important means of media is print media. Print media is the first means of media when mentioned about media. Newspapers are means through which people are always kept up to date about the latest news in civilized societies. With this regard, the most basic purpose of this study is to investigate the news about the mobbing events experienced in higher education system under the light of national policy documents and reports. The study was carried out based on a qualitative approach. The news released in print media was chosen purposefully as print media means report news in a detailed way, have an evidential value and can be read again on demand. The research group in this study consists of the mobbing news released on Hurriyet, Sabah and Zaman which are newspapers published in Turkey between the years of 2009-2013. These newspapers were purposefully chosen based on criterion sampling method. The most basic understanding underlying this sampling method is to study on all cases which meet the standards set prior to the start of the study. The newspapers mentioned above were chosen considering that they are published nationally, reference newspapers and belong to different publication groups. The data used in this study was taken from the archive of the three newspapers. When the archives of the newspapers was scanned, the word “mobbing” was taken as key word for the search. In qualitative researches, newspapers are considered to be public archive and used as reference documents. The data obtained was grouped depending on the newspapers which it was taken from, on the year of publication, on where they took place, on the gender of the victims and on who the sufferers are.

Authors: Soriano-Ayala Encarnación , Cala Verónica C. 
Published: November 2015

Abstract
Introduction: Globalization has favored intra-European Commission (EC) and extra-EC migration to Spain. One of the most numerous cultural groups that have settled in the southern Spain is from Romania. Coexistence, especially in schools, has made us become interested in knowing the eating habits at breakfast of Romanian and Spanish populations. Numerous studies show that the food intake at breakfast, mostly made before leaving home, has an incidence on the physic wellbeing of adolescent throughout the day. The processes of acculturation are also inseparable from the eating habits, health and life, that maintain the migrant teenagers. Breakfast is analyzed as one of the habits more associated with diet quality; paradoxically, one of the findings of our study, many adolescents do not take a proper breakfast every day.
Objectives: The study analyzes the characteristics and the main cultural and gender differences in the implementation of breakfast: its maintenance or omission in young autochthonous and immigrants of Romanian origin in the southeast Spanish schools. Design. This is a cross-sectional study with a cluster sampling in two Primary schools and seven Secondary schools. The instrument applied was an adaptation of the KIDSCREEN-27 questionnaire. Sample. It has been formed by 1472 students between 11 and 18 years old; nationality: 1315 were Spanish and 157 were Romanians. Data analysis. Descriptive and differential analyses using the chi-square and U of Mann-Whitney statistics.
Results: In the study we identified 1.2% of Spaniards and 3.3% of Romanians who either skip breakfast or do not eat foods throughout the morning. The main breakfast foods of the Spanish students are dairy, bread and cereals, cookies, juice and olive oil; for the Romanian students the basic foods at breakfast are cereals, dairy products, juices, biscuits and jams. We have found significant differences between the two compared cultural groups. We also found significant differences between the food eaten by men of the two cultural groups (Spanish and Romanian) and by the food eaten by women (Spanish and Romanian) in the breakfast food.
Conclusions: The results show the need to further promote and implement educational programs that encourage students to make breakfast before leaving home. Also, it is necessary, they take care of the intake of the right foods to start the day and contemplate this habit from a transcultural and gender approach. Significant differences were identified in the breakfast practice food by both genders and cultural groups.

Published: November 2015

Abstract
Nowadays new education technologies and e-communication devices give new measuring and assessing tools for researchers. Eye-tracking is one of these new methods in education. In our study we assessed 4 figures from the anti-smoking heath issues of National Institute for Health Development. In the study 22 students were included from a 7th grade class of a Kecskemét primary school. Our results show that students concentrate on the text-part of the figures except if the picture is frightening. However if the text and the picture are not both frightening enough, the message will not be transferred to young students.

Thermal insulating epoxy composite coatings containing sepiolite/hollow glass microspheres as binary fillers: morphology, simulation and application
Authors: Wang Jinwei , Tian Yunpei , Zhang Jin 
Published: November 2015

Abstract
Sepiolite and hollow glass microspheres (HGMs) are used as binary fillers to prepare thermal insulating composites to improve the protecting durability of epoxy composites on Mg alloy. Sepiolite can be evenly dispersed inside epoxy at around 10% (vol.%), while HGMs are also found evenly distributed in this matrix with content up to 45% (vol.%), as shown in the scanning electron microscope pictures. Their thermal stability and thermal insulation ability improve simultaneously with the increase of the inorganic filler, as shown in the thermal gravimetric analysis results and thermal insulting tests. According to the three-dimensional finite element analysis using ANSYS software (ANSYS Inc., USA), their thermal conductivity coefficients are found to decrease linearly with the increase in HGMs volume fractions. The tested temperature changes on the opposite side of the Mg alloy coated with sepiolite/HGMs/epoxy composites match well with those on the stimulant curves, indicating the reliability of the models and the thermal insulating functions provided by the fillers.

Authors: Krivchenkov Aleksandr , Sedykh Dmitry 
Published: November 2015

Abstract
The networks with wireless links for automation control applications traffic transmission when packets have small size and application payload is predictable are under consideration. Analytical model for packets delay on their propagation path through the network is proposed. Estimations for network architectures based on WiFi and Bluetooth wireless technologies are made. The specifications for physical layer 802.11 a/b/g/n and 802.15.1 are under consideration. Analytical and experimental results for delivered network bandwidth for different network architecture, traffic structure and wireless technologies were compared to validate that basic mechanisms are correctly taken into account in the model. It is shown that basic effects are taken into account and further accuracy “improvement” of the model will give not more than 5%. As a result that is important for automation control applications we have reliably received the lowest possible level for packets delay in one wireless link. For 802.11 it is of order of 0.2 ms, for 802.15.1 it is 1.25 ms and is true when application packet can be transferred by one data frame.

Published: November 2015

Abstract
In this paper, the determinant representation of the n-fold binary Darboux transformation, which is a 2×2 matrix, for the Ablowitz–Kaup–Newell–Segur equation is constructed. In this 2×2 matrix, each element is expressed by (2n+1)-order determinants. When the reduction condition r=–q̅ is considered, we obtain one of binary Darboux transformations for the nonlinear Schrödinger (NLS) equation. As its applications, several solutions are constructed for the NLS equation. Especially, a new form of two-soliton is given explicitly.
Reptilia, Squamata, Leptotyphlopidae, Leptotyphlops, Ecuador: re-evaluation of the species cited for the country
Authors: Cisneros-Heredia Diego F. 
Published: November 2015

Upon analysis of the information supporting the inclusion of different Leptotyphlops taxa as part of the herpetofauna of Ecuador, I conclude that Leptotyphlops anthracinus, L. guayaquilensis, and L. subcrotillus are the only species with confirmed records from the country. Leptotyphlops anthracinus and L. guayaquilensis are Ecuadorian endemics and the presence of L. subcrotillus is supported herein by publication of data about the first vouchered specimen. Leptotyphlops signatus and L. tenellus should be excluded from the reptile fauna of Ecuador because all previous records where based on misidentified specimens or specimens of uncertain origin. Studies on the ly needed. Several unidentified specimens are deposited in museum collections and may correspond to new distributional records or unnamed taxa.

Authors: Molkenova Anara , Kato Seitaro , Taniguchi Izumi 
Published: November 2015

ABSTRACTNano-sized SiOx/C composite was successfully prepared by drip combustion in a fluidized bed reactor. A mixture of tetraethyl orthosilicate (TEOS) ant kerosene at a 2:3 volume ratio was used as a precursor solution. The synthesis was carried out between 600 °C and 900 °C. The as-prepared powder (600 °C) consists of SiOx and carbon particles which are approximately ranged from 30 to 80 nm. For the nano-sized SiOx/C composite sample, the heat treatment process was introduced to remove incomplete combustion materials and the dry ball milling was performed to homogenize the distribution of carbon inside the sample. The final sample (nano-sized SiOx/C nanocomposite) was used as an electrode active material and then electrochemical testing was performed. The cell exhibited discharge and charge capacities of 1158 and 533 mAh g-1, respectively, at current density of 50 mAh g-1 in the voltage range between 0.01-3 V versus Li/Li+.
Factors on Zakat (Tithe) Preference as a Tax Deduction in Aceh, Indonesia
Authors: Nurhayati Sri , Siswantoro Dodik 
Published: November 2015

This paper aims to analyze the variables that affect zakat preference as a tax deduction. Samples are also analyzed and grouped to see some characteristics and patterns of specific issues. Structural Equation Model (SEM) is based on variance. SmartPLS is used to evaluate which variables affect the zakat preference. Samples are distributed to zakat institutions and the University in Aceh, Indonesia. Crosstab analysis can enrich the analysis of the paper. Very few people are aware of zakat as a tax deduction; however, the other permitted regulation of zakat as a taxable income deduction has not been approved by local government. In addition, only a few people have tax numbers that are used to claim overpaid tax (restitution). Surprisingly, motivation factor significantly affects zakat preference in a negative way. On the other hand, satisfaction factor is similar to Siswantoro and Nurhayati’s 2012 findings, which is negative and insignificant. Motivation factor is positive, but insignificant.
