Diagnostic hystero-laparoscopy in work-up of female infertility
Authors: Rai Amrita , Mishra Manju G.
Published: June 2017

Background: Infertility is a growing concern of the society. In many cases the exact cause of infertility may not be elucidated, whether it is tubal, ovarian, uterine, or a combination of factors. This paper aims to understand the role of diagnostic hystero-laparoscopy in evaluation of cases of infertility.Methods: This prospective study included 200 infertile women and it was conducted at department of Obstetrics and Gynaecology, MGM Hospital, during the period between January 2016 to December 2016. All the infertile patients either with primary or secondary infertility were included after thorough evaluation.Results: Out of 200 cases, 118(59%) patients had primary infertility and 82(41%) had secondary infertility. While laparoscopy detected abnormalities in 49% of the cases, significant hysteroscopy findings were noted in only 23.5% of cases. The most common laparoscopic abnormalities were endometriosis (32%) and unilateral tubal lockage (24%). On hysteroscopy, periosteal adhesions were the commonest abnormality in both the groups.Conclusions: Diagnostic hystero-laparoscopy is a safe and cost-effective method and should be considered when there are abnormal HSG results, a past history of pelvic infection, pelvic surgery and /or unexplained secondary infertility during management of infertile couple. Evaluation of certain significant and correctable tubo-peritoneal and intrauterine pathologies which are usually missed by other imaging modalities, can be diagnosed as well as managed in some cases by hystero-laparoscopy.

Published: June 2017

Background: The misuse of licit and illicit substances has continued to constitute a profound effect and harm across various societies. This study examined the nature of substance use, abuse and dependence in a community setting in Jos, Plateau State and the ease of carrying out screening, brief intervention and referral for substance use problems.Methods: Data for this study was gathered through a community-based medical outreach with a total of 1170 residence (M=36.97, SD=15.33), within the research area in participation. A cross-sectional research design was used to examine the prevalence and correlates of psychoactive substance consumption (excluding alcohol).Results: Analysis revealed that tobacco 51%, marijuana 22%, opioids 15%, sedatives 6%, and amphetamine 2%, were the current most significant substances used within the population. The ASSIST and MINI diagnostic criteria noted a significant rate of substance abuse and dependence (p<0.05) for tobacco, marijuana, amphetamine, inhalants, sedatives, hallucinogens, and opioid. Brief intervention based on the FRAMES techniques as employed in this study, was used in a total of 211 participants among whom 36 further received counseling for substance abuse and 60 were referred for specialized drug treatment therapy due to substance dependence. Gender, living environment, employment status and occupation were significant predictors of substance use across the participants. Specifically, male, participants who have stable accommodation, those with regular employment and students were found to be the group with the most significant rates of substance and substance use disorders.Conclusions: This study concludes among others, that the ASSIST, MINI and Brief Intervention were indeed effective for substance-related diagnosis in community-based medical programs and can be effectively incorporated into routine services with adequate planning, training and execution.

Authors: Balasankar Soundaiyan , Balasubramanian Jeyaraman
Published: June 2017

Background: Tuberculosis (TB) is a chronic infectious disease caused by mycobacterium tuberculosis and one of the major disease affecting children throughout the world. Prevalence of active disease in adults in India is 18 per 1000 population. The aim of the current study was to see whether reading Mantoux test at 24 hours can predict Mantoux positivity at 48 hours.Methods: A Prospective observational study was conducted in Tertiary care hospital which caters for people in and around Madurai, Tamil Nadu, India. Total 6560 children in the age group of 6 months to 12 years with suspicion of Tuberculosis. (Positive contact history or Low weight for age or persistent fever for more than 2 weeks or cough for more than two weeks or significant lymphadenopathy) were given Mantoux test. Of these 5904 (90%) children turned up for 24hours and 48 hours reading. Transverse diameter of the induration was measured. More than 10mm was considered as Mantoux positivity. The size of induration at 24 hours and 48 hours were compared.Results: Out of 5904 children, 206 (3.48%) children had Mantoux positivity at 48 hours. Of these 206 children, 131 (63.6%) children had more than 10 mm at 24 hours. Remaining 75 (36.4) showed less than 10 mm at 24 hours, but become more than >10 mm at 48 hours. Overall tuberculin positivity is 3.5%.Conclusions: Positivity of tuberculin test must be confirmed at 48 hours only. There is no standard reading at 24 hours which can be presumed to become positive at 48 hours.
Prospective lines of improving the process of evaluating the technical condition of aircraft hydraulic system working fluid
Authors: Koptev A. N. , Gareyev A. M. , Popelnyuk I. A.
Published: June 2017

The article is devoted to the evaluation of the technical condition of aircraft hydraulic system working fluids. Working fluid parameters (concentration of impurities, viscosity, density, anti-oxidation, anti-wear and thermal properties) determining its technical condition are selected on the basis of a study of scientific and technical literature. The peculiarities of the existing process of its evaluation are discussed. A structural grapho-analytical model reflecting the condition of the working fluid was developed. The model takes into account the influence of the fluids basic parameters as well as reachability and counter-reachability matrices. Analyzing the results, it was found that the graph components are strongly interconnected. Viscosity is closely linked with anti-wear and thermal properties, while variations in mechanical impurity content in the working fluid cause variations in the rest of its parameters. Thus, we can say that the assessment of the working fluids condition based on measuring only its purity and viscosity is not quite reliable. We substantiate the future line of research with the aim of developing new methods to assess the condition of the working fluid, namely, development of mathematical models of the working fluid condition taking all its components into account.
Types of aeroelastic vibrations of turbomachinery bladed discs
Authors: Koskin A. O. , Seleznev V. G.
Published: June 2017

A real process was analyzed for presence of self-oscillations. Absence of self-oscillations was revealed as its attributes such as progressive wave and beating were not discovered. A model of oscillatory process was proposed on the basis of the kind of oscillograms and the linear superposition theory for several simultaneously excited oscillation modes. In accordance with the theory two vibrations with frequencies equal to 919 and 469Hz were summed up. As a result of addition of these frequencies and comparison of the derived oscillograms with the real process it was found that the proposed model agrees with the original well enough. Moving further into the process, a third frequency component equal to 1002Hz originates in addition to those of 465 and 918 Hz. Addition of three frequencies carried out similarly to the first example also yields a satisfactory result. Oscillograms of real and model processes have a similar appearance. The frequency components calculated on the basis of the oscillogram of the model process practically coincided with the real process frequencies. Classification of aeroelastic oscillations was analyzed in order to determine the oscillatory type of the process under investigation. Three main phenomena were distinguished: forced oscillations, flutter and non-synchronous oscillations. Almost all foreign engine companies faced the latter phenomenon, sometimes mistaken for flutter. The analyzed example was labeled as non-synchronous oscillations according to features of non-synchronous oscillations, namely, aliquant rotation frequency and resonant behavior of oscillations.
On the efficiency of a radiant heating regenerative system
Authors: Panchenko V. V.
Published: June 2017

A scheme of a radiant heating regenerative system is developed on the basis of a two-flow heat generator, a system and form of heat-radiating air ducts is proposed. It is shown that the system of radiant heating is more efficient as compared to the conventional convection system. The climatic conditions in Samara Region make it necessary to provide heating of houses for at least 200 days a year. Traditionally, the convective scheme of heating is used wherein radiators installed near the floor are used. Water serves as the working fluid in the radiators. The proposed radiant heating regenerative system is based on the transfer of heat in the form of infrared electromagnetic radiation. Air acts as the working fluid in the system. A microclimate with the required level of moisture and content of oxygen is created inside closed premises. Ways of using the systems described are suggested and recommendations on the necessity of conducting further research are given.
Selection of reference specimens for assessing the efficiency of part surface nitriding
Authors: Sazanov V. V.
Published: June 2017

The use of corset reference specimens for carrying out fatigue tests and smooth reference specimens for determining residual stresses in a surface layer to assess the sufficiency of nitriding (thermochemical processing) is substantiated in the paper. The calculations are carried out by finite element simulation using the ANSYS and PATRAN/NASTRAN software complexes. The ANSYS complex is used to determine the stress concentration factor for the case of corset specimen bending. The employed models with harmonic axisymmetric finite elements make it possible to find the stress concentration factors in the case of tension- and- compression and bending of body-of-rotation parts. The obtained value of the influence of the coefficient of residual stresses on the endurance limit increase is in quite good agreement with its experimental values for nitriding and other types of thermochemical treatment of corset specimens. The PATRAN/NASTRAN complex is used to calculate the stress-strain state in corset specimens depending on residual stresses arising on a part surface under nitriding. Modeling is performed by the thermoelasticity method, with experimental diagrams of residual stresses in smooth specimens used as initial data. It is established that the distribution of axial residual stresses in the dangerous (smallest) section of a corset specimen practically does not differ from the distribution in smooth specimens. The results obtained provide the basis for determining average integral residual stresses by the distribution of residual stresses in smooth specimens and using them to calculate the endurance limit for hardened corset specimens. The results of the study allow making a conclusion that the most optimal nitriding practices are those wherein the average integral residual stresses are maximal.

Authors: Golyakov A. D. , Fominov I. V. , Korolev S. Yu.
Published: June 2017

The article presents the results of analysis of the accuracy of autonomous navigation of a space robot in solving tasks of remote diagnostics of the technical condition of an orbital object in coplanar orbits. The angle between the stellar line and the direction of the orbital object, the distance to the orbital object and the rate of its change are taken as the primary navigation parameters measured onboard of a space robot. The space robot navigation accuracy is assessed on the basis of an analytical method. Assumptions of the normal law of distribution of measurement errors with known characteristics, the motion of the space robot and the orbital object in the central gravitational field of the Earth and the equality of the heights of their reference orbits are introduced. As a result of research covariance matrices of errors of determining the parameters of space robot center-of-mass motion were obtained in analytical form. The analysis of the accuracy of autonomous navigation carried out in the present paper can be used at the stage of feasibility study of the conceptual design of the control and navigation system of a space robot, for example, when solving the problem of choosing the composition of the onboard equipment, determining the accuracy specifications of onboard measuring devices and the amount of measurements carried out within the navigation mode.

Published: June 2017

The geographic location of the Russian Federation determines regional apartness of the Arctic and Far East territories which are mostly isolated. The necessity of development of the Russian North Polar regions calls for the development of transport infrastructure and specifies requirements to flight characteristics of regional airplanes, which requires new research and development solutions. Positioning the Arctic territory as an exclusive economic zone on the world political arena necessitates the development of the regional transport network including all-cargo and passenger services for sustainable development of the region. An up-to-date approach to aircraft design should be based on Arctic exploiation requirements, infrastructure-climate limitations and design methods that include methods of moment-inertia analysis, structural-parametric analysis of Arctic-based aircraft taking into account the choice of rational moment-inertia configuration. Synthesizing the limitations and required operation characteristics we designed an Arctic-based airplane that can perform transport operations in the Russian Arctic zone safely and successfully.

Authors: Berestovitskiy E. G. , Kizilov P. I. , Kruchkov A. N. , Pialov N. V.
Published: June 2017

We present the results of modeling a feed water control system. The system contains two regulatory devices the feed valve to control the flow rate, with electrohydraulic control, and the throttle valve to maintain constant pressure differential on the feed valve, with hydromechanical control. The valves have perforated flow parts to reduce hydrodynamic noise and vibration, which necessitates checking the dynamical characteristics of the system. The model was developed on the basis of equations describing the electrohydraulic converter dynamics, a differential pressure meter, a servo drive and flow parts with the use of Matlab Simulink. The modeling of dynamical processes caused by various disturbance inputs and control actions showed the compliance of the system with the requirements imposed on it.

Published: June 2017

The article considers the influence of different tolerance values on the stiffness of elastic rings in squeeze film dampers. This type of damper is widely used in gas turbine engine supports. The available analytical solutions have a number of limitations. A parametric finite-element model of an elastic ring, a set of two interconnected elastic rings and a simplified segment is presented. The results obtained show the discrepancy between values of compliance for different numerical models as compared to analytical approaches. The effect of assembly tolerances on the value of compliance is shown.

Authors: Nasihatkon Banafsheh , Kheiri Jamal , Miralbell Oriol
Published: June 2017

Celem badań ilościowych była analiza roli mediów społecznościowych w marketingu hoteli irańskich za pośrednictwem Internetu. Zastosowano technikę kwestionariuszową na próbie 149 marketerów zatrudnionych w dziale marketingu sieci Parsian International Hotels. Do oceny danych zastosowano program SPSS. Przeprowadzono testy Kolmogorowa-Smirnowa, Cochrana, regresji, według współczynników niestandaryzowanych i standardowych. W oparciu o wyniki możemy stwierdzić, że media społecznościowe nadal nie stanowią istotnego narzędzia marketingowego w hotelach irańskich. Facebook i YouTube są mediami najczęściej wykorzystywanymi do celów marketingowych, jako że filmy oraz zdjęcia mogą być używane na ich stronach w większym stopniu niż na innych. Wyniki pokazują, że możliwości marketingowe Parsian Hotels rosną wraz z powszechniejszym korzystaniem z mediów społecznościowych, jednakże sektor marketingu hotelarskiego na razie nie traktuje Internetu jako odgrywającego najistotniejszą rolę narzędzia marketingowego.

Authors: Jadav Mehul M. , Kumar Niranjan , Das Bhupamani , Solanki Jaesh B.
Published: June 2017

The objective of the present work was to standardize and evaluate indirect plate and dot- enzyme linked immunosorbent assay (ELISA) using purified Paramphistomum epiclitum homologous antigens in the small ruminants. Electrophoretic separation of somatic antigen (PeSAg) in reducing condition on 15% polyacrylamide gel resolved into 16 proteins of the molecular weight ranging from 14 -100 kDa. Two step ethanolic precipitation of supernatant of in-vitro culture of the fluke yielded P. epiclitum excretory-secretory antigen (PeESAg) of molecular weight 28 kDa. The animals (Goats=123; Sheep=91) were broadly kept into post-mortem and faecal examined groups. At many occasion the PeSAg found to cross reacts with other helminths parasites thus minimizing the specificity of the tests and antigens. There was no any direct correlation between the parasites load and ELISA reactivity pattern. The noted prevalence rate after combining the results of post-mortem examination and PeESAg based ELISA (plate and paper/ dot) was 30.08% (37/123) in goats and 28.57% (26/91) in sheep. While using PeESAg, the calculated overall sensitivity% was 92.86 (goats)/ 100 (sheep) in both plate and dot-ELISA, specificity% was 91.58 (goats)/ 91.55 (sheep) in plate ELISA while 88.42 (goats)/ 92.96 (sheep) in dot-ELISA, positive predictive value% was 76.47 (goats)/ 76.92 (sheep) in plate ELISA while 70.27 (goats)/ 80 (sheep) in dot-ELISA and negative predictive value% was 97.75 (goats)/ 100 (sheep) in plate ELISA while 97.67 (goats)/ 100 (sheep) in dot-ELISA, these values were optimum for the field sera sample so the tests and PeESAg can be recommended for the detection P. epiclitum infection in the small ruminants.
Permanent Peace Amid The Warlike World
Authors: Babasyan Tigran
Published: June 2017

Until now the dichotomy of war and peace has tracked two paths: one in tune with the Roman maxim «In peace prepare for war» and the other begotten by the ongoing apocalyptic craze for the end of the world and could be tentatively worded like this: “Wage wars to get peace.” Meanwhile there is a flexible and fairly feasible construct to operate in order to reach the balance in war- and -peace things. It is the cause-and- effect relation where war always stands for the effect that, weirdly enough, stems from peace. Does it mean that the real cause of war is engendered in peace? It usually is that way if the peace is established on a loose soil: but when built on the solid ground it devours all those who are in the way of peace. We mean the river of eternal life flowing between the two dichotomic banks: “I will send peace flowing over her (Jerusalem) like a river, and the wealth of nations like a stream in flood.” (Isaiah 66:12) (The New English Bible,1970). How to reach the banks of this river of disambiguation will be the thrust of our deliberations below.

Authors: Garza Gaspar Eduardo Fuentes
Published: June 2017

The objective of this article is to analyze the performance evaluation of the service area in an organization. There are differences in the results based on the self-evaluation of the performance of its employees and a final evaluation by its leader (direct supervisor). In carrying out this work, the information of more than 3,000 employees was obtained from the Human Resources area. The result of this comparison shows that 62.5% of the employees had a self-evaluation that does not coincides with the one carried out by their leader. For 37.5% with coincidence which demands more training for the writing of the objectives, there is a greater participation of the leader in the process of performance management. This is achieved by clearly communicating the objectives of the organization and also reporting how performance management is managed.
The Relationship Between NATO and Russia Through the Prism of Mutual Cooperation and Confrontation
Authors: Temelkovska-Anevska Elena
Published: June 2017

The aim of this paper is to analyze the relationship between NATO and Russia, to explain the historical background of their relationship, to detect challenges of their relation and to specify the potential future areas of cooperation. Some of their policy objectives are overlapping, so the cooperation enables them to accomplish these important objectives. Although NATO became the most powerful military international organization in the world, over the years, it confronts strategic challenges and dilemmas divided in two groups: existing and new. These challenges included Russia’s aspiration for dominance, developments in Afghanistan, terrorism as an international risk, the Arab Spring, China as a global player and turn of the United States foreign policy toward the Asia-pacific region. This paper will focus on one of these challenges: Russia’s ambitions for dominance and its influence on NATO-Russia relationship, identifying specific areas and issues of cooperation and confrontation. In the foreseeable future, NATO needs to focus on challenges and developments of a strategic importance for the Alliance, such as the innovative efforts for enhanced relationships, limited missions, operations and a realistic combination of solutions that can serve the principles and values of all NATO allies, including the most influential.
Situación Del Emprendimiento Y Sus Alcances En El Ecuador
Authors: Borja René Mesías Villacrés
Published: June 2017

Entrepreneurship, over the last 20 years, has been of vital importance throughout the world. Also, many educational institutions have been concerned with creating careers in these areas, especially when a serious research such as the GEM was followed due to several years of entrepreneurship activity. Many countries have sought to promote the entrepreneurial spirit through actions aimed at providing training, incentive for business start-ups, and financing. This, however, is based on the fact that entrepreneurship is considered as the motor of a country's development, especially in times of crisis. In Ecuador, entrepreneurship plays an important role in the generation of employment, investment, production, consumption, and income for the state. These roles are attributable to the fact that Ecuador is a country where entrepreneurship is generated by opportunity and necessity. The present research is of a bibliographical character since it uses documents which were based on statistical information and other sources in which the situation of the enterprise was analyzed. Analytical method was used to obtain real information based on observation and analysis. It is also based on the inductive part of a particular situation. In general, it derives knowledge that are proposed. The deductive method starts from general data and through logical reasoning, it comes to a particular consideration and conclusion. The objective of the research is to analyze the beginning of entrepreneurship in the current situation in Ecuador.

Published: June 2017

This work aims at diagnosing the Moroccan high school students’ difficulties in perceiving and mobilizing the time and space parameters, particularly through the study of the concepts of fossils. To attain our objective, first, an analysis was carried out on Life and Earth Science programs in Moroccan high school. Then, the results achieved by the Nominal Group Technique (NGT) have enabled us to elaborate a questionnaire related to the concept of fossils. These investigation tools affirm that the students have difficulties in assimilating and mobilizing the time and space parameters, particularly while overvaluing the time factor at the expense of the space one, a confusion in the mobilization of the temporal scales and inability to imagine the succession in time and space of the different stages of the fossilization. To reduce the difficulties faced by the learners, we suggest some pedagogical solutions.

Authors: Ikyanyon Darius N. , Ode Egena
Published: June 2017

Due to the importance of knowledge transfer in enhancing competitive advantage of firms, organizations are increasingly developing strategies for effective knowledge transfer. This study examined the relationship between high-performance HRM and knowledge transfer as well as the mediating effect of affective commitment on this relationship. The study is based on data from 136 mangers drawn from six banks in Nigeria. Through the use of regression analysis and mediation analysis using PROCESS macros, we report a positive relationship between highperformance HRM and knowledge transfer. We also found a positive relationship between affective commitment and knowledge transfer. In turn, affective commitment mediated the relationship between high-performance HRM and knowledge transfer. The study therefore concluded that highperformance HRM contributes to knowledge transfer directly and indirectly through affective commitment.

Information and communication technology (ICT) in education has currently become an unavoidable pedagogical tool in any educational system of high standards. Its integration signifies a change in the learning processes and knowledge transmission and acquisition. In this article, we present the results of an exploratory research that we led with engineering science teachers of the Mechanical Science and Technology stream in high schools belonging to two regional Moroccan academies (Grand Casablanca, Settat and the Oriental). Our study focuses on the identification of the unknown current state of affairs and related to the integration of ICT in this subject of secondary education of the Mechanical Science and Technology stream in Moroccan high schools. The results have shown that 95% of the interrogated teachers displayed a big interest towards the usage of ICT in their teaching practices whilst only 22.5% of them already integrate it regularly in the classroom. This paradox is chiefly due to a shortage of equipment within the institution, the lack of software and applications suitable for E.S as well as teachers’ qualification and training. We also estimate that this research’s results could prove useful to other streams while the integration of ICT in the training of future teachers and in the practices of the classroom still remains problematic.
The Terrorism of ‘Counterterrorism’: The Use and Abuse of Anti-Terrorism Law, The Case of Ethiopia
Authors: Kibret Zelalem
Published: June 2017

Since its enactment on July 2009, Ethiopia’s anti-terrorism proclamation was/is at the very center of almost every political discourse in the nation. Many dissidents fall into its trap and by day its effect is becoming more far-reaching and resonating. The widely written provisions of the law make it susceptible to misapplication and prone to abuse. Whilst the state is staunchly firing back to the detractors of the law and its mis(application), however, it doubled down its implementation by every new day. This paper, after examining one hundred twenty three terrorism charges against nearly one thousand individuals―in a sixty-six months period of time―concludes that: Ethiopia’s anti-terrorism law is a colossal failure for counterterrorism, which only exemplifies how not to counter terrorism.

Published: June 2017

The article aims to analyze the degree of professional motivation of the teachers of primary schools in the periphery of zone B in the development of their teaching activities, in a population of 271 subjects and a final sample of 200 teachers and 4 directors. To carry out this research, a questionnaire was applied to teachers that follow a Likert scale, with 71 variables related to professional motivation. Interviews were also conducted with members of the selected schools. Different statistical analyzes were carried out for the processing of the collected information, such as the application of the test of the two halves of Guttmann and the coefficient of Spearman Brown, with a reliability of the results showing the internal consistency of the instruments used in this study (0.993). The results indicate that teachers outside schools have a professional motivation level lower than school teachers in urban areas, given the numerous labor difficulties they face daily in schools. From the perspective of teachers, their level of job satisfaction can improve when they see that the basic problems that have to do with their professional success are solved, including among these solutions the decrease in the number of students in the classes.

Le Droit À L’eau: Un Droit Fondamental Des Autres Droits De L’homme
Authors: Tak Ziad
Published: June 2017

The right to water is a right for all and must be implemented in a nondiscriminatory manner in accordance with the conditions and limits laid down by some particular laws and regulations. In order to make the right to drinking water and sanitation a reality, water and sanitation services must be made affordable to the population as a whole. Property and access to other human rights such as the right to housing, food or health services should also be made available to the population. Internationally, several countries have recognized the right to drinking water and sanitation, but have not actually implemented it at the national level. The objective of this study is to show the importance of the implementation of the right to drinking water, so that it can be made available to all. Since the most widely traded studies on human rights were dominated by political and judicial character, I tried in this study to broaden the meaning of human rights and to provide more Rights. This is despite the fact that it has not been compensated by specific legal texts. As a result, the problem of the study is focused on water as a fundamental need of human, and access to water is part of its fundamental rights.
Study of the Effect of RCS on Radar Detection
Authors: Ali Haitham Kareem
Published: June 2017

Objectives: To study the effect of the radar cross section (RCS) area for the target on the radar operation, and to show its performance on radar detection by taking samples from the RCS. Methods/Statistical Analysis: In this paper, we tested the effect of RCS on radar detection under two features of RCS using radar lab. These features are: (i) shapes with constant area and (ii) shapes with different areas. Findings: Experimental testing of the radar delectability in order to know its capability in detecting targets under and above two features( by measuring the power of echo signal) shows that whenever the power of echo signal is high (i.e. RCS is an excellent reflector), the radar detection range is high and vice versa. Application/Improvements: This proposed approach can be used in designing the target bodies using different shapes (i.e. reflectors) to dispute the transmitted signal and to weaken it. This makes the detection of targets extremely hard.

Objective: To assess the effect of vegetation cover on soil macrofauna, a study focused on the diversity of soil macrofauna inside and outside reforestation plots of the Great Green Wall in Senegal was carried out. Methodology: The sampling of macrofauna was performed according to the method recommended by the TSBF network (Tropical Soil Biology and Fertility). It involves isolating 10 ground plots along a transect of 50 meters chosen at random in each plot and outside of each plot. The macrofauna was sampled between February and July 2016 during the dry season Results: The results show, in order of importance Hymenoptera, Isoptera, Coleoptera, the Spiders, the isopods and springtails are the taxonomic groups of the study area. The density of each of these taxa is larger inside and outside of the plots. The vertical distribution of macrofauna shows that the 0-10 cm layer is more densely populated than the deeper layers. Conclusion: This study showed a low diversity of soil macrofauna in the area. It also shows that the vegetation cover affects the density of the macrofauna.

The mineralogical investigation of sand fraction of different sectors of filling of Montgaudier deposit revealed that heavy minerals are mainly composed of amphiboles and disthene in all analyzed samples. The other mineralogical species encountered appear having only a secondary role in the composition of heavy mineral processions. These minerals are: Andalusite, brookite, chlorite, epidote, garnet, pyroxene, rutile, sillimanite and sphene. The opaque minerals are relatively numerous in all the studied samples which they are in different stages of alteration, associated with other minerals presenting a fresh appearance. The light minerals consist mainly of hyaline or translucent quartz grains and milky or opalescent grains. The study of clay minerals generally showed a predominance of kaolinite in all sectors, followed by illite and chlorite. Smectite comes in only fourth place. This cortege is complemented by interstratified smectite-chlorite, which are very poorly represented. The mineralogical study of the deposits at the different parts of the layers filling of the Montgaudier deposit and the sediments in the immediate vicinity permitted to determine the origin of these deposits. Their procession is largely influenced by the geological nature of the Tardoire watershed but also of the mineralogical composition of the surrounding rock in which this cave was.
An Improved Multi-Hop-Enabled Energy Efficient MAC Protocol for Underwater Acoustic Sensor Networks

Published: June 2017

Packet collisions occurred by hidden and local nodes in multi-hop enabled underwater acoustic sensor networks (UWASNs) have effect on throughput, energy efficiency and end-to-end delay. Existing Multi-HopEnabled Energy Efficient MAC Protocol for Underwater Acoustic Sensor Networks (MHEE MAC) utilized a double-phase contention resolution mechanism, which causes visit multiple time slot and energy overhead. In this paper, we propose a MAC protocol that use contention resolution mechanism with unique priority to provide energy efficiency. First, local nodes are eliminated comparing their priority and later, hidden nodes are mitigated. A simulation of proposed protocol is also developed to analyze the performance. Results obtained through simulation show that the proposed protocol achieves significantly lower energy consumption, reserve more energy and more stable throughput compared to MHEE-MAC, T-Lohi and slotted floor acquisition multiple access (S-FAMA).

Trichloroisocyanuric acid is a swimming pool disinfectant and is readily accessible. As a result, there is the need to use it as a substitute for conventional disinfectants in in vitro culture. Nodal explants of Alchornea cordifolia, harvested in a natural environment, have been rinsed abundantly with Dettol under running water. Then it was soaked in Talo Plus (550 g/l carbendazim and 100 g/l Chlorothalonil) at 5 ml/liter, which is a broad spectrum fungicide. After then, it was immersed in 70% alcohol for 10 minutes before being soaked in different solutions of trichloroisocyanuric acid to: 6, 4, 3, 2, 1, 0.3, 0.1, and 0.08%. The explants were disinfected completely of all contaminating bacterial and fungal exogenous. This was after a treatment in solutions of acidic trichloroisocyanurique of 6 to 0.08%. The results showed that the losses of active chlorine remained low during storage at temperatures of 4 to 18 ± 2°C. They reach only 5.29% after 72 hours. At room temperature of 27 ± 2 ° C, these losses are more than 30% after three days. Concentrations of 0.1 to 0.3% are effective for the disinfection of explants. This protocol of explants disinfection in vitro culture could therefore be advantageously substituted using the hypochlorite of calcium or the chloride of mercury.

Minimal Intervention Dentistry (MID), a concept that aims to minimize the interventional procedures applied on teeth affected by dental caries, emphasizes the importance of prevention and detection of lesions in early stage. The white spot lesion (WSL) is the first visible stage of the carious process, affecting the enamel. Their detection and treatment has been significantly improved in the last decade through new technology available. Our paper describes a non-invasive detection method, using a lighttransmission device (transillumination of the teeth using Diagnocam, by Kavo) , combined with a resin infiltration technique (using Icon, by DMG) of the WSL.
