Using the Equivalent Fiber Approach in Two-Scale Modeling of the Elastic Behavior of Carbon Nanotube/Epoxy Nanocomposite
Authors: Javadinejad Mahdi , Mashayekhi Mohammad , Karevan Mehdi , Hadavinia Homayoun
Published: September 2018

In this study, the mechanical behavior of epoxy/carbon nanotubes (CNTs) nanocomposite is predicated by a two-scale modeling approach. At the nanoscale, a CNT, the interface between the CNT and the matrix and a layer of the matrix around the CNT are modeled and the elastic behavior of the equivalent fiber (EF) has been identified. The CNT/epoxy interface behavior is modeled by the Park–Paulino–Roesler (PPR) potential. At the microscale, the EFs are embedded in the matrix with the extracted elastic properties from the nanoscale model. The random pattern has been used for the dispersing of EFs in the representative volume element (RVE). The effect of CNTs agglomeration in the epoxy matrix has also been investigated at the micro level. The Young’s modulus of the nanocomposite was extracted from simulation of the RVE. CNT/epoxy nanocomposites at four different volume fractions were manufactured and the modeling results were validated by tensile tests. The results of the numerical models are in good agreement with the experiments and micromechanics theory, and by considering agglomeration of CNT in the model, the modeling results match with the experiments.
She’s Electric—The Influence of Body Proportions on Perceived Gender of Robots across Cultures
Authors: Trovato Gabriele , Lucho Cesar , Paredes Renato
Published: September 2018

The assignment of gender to robots is a debatable topic. Subtle aspects related to gender, in a robot’s appearance, may create biased expectations of the robot’s abilities and influence user acceptance. The present research is a cross-cultural study involving more than 150 participants to investigate the perception of gender in robot design by manipulating body proportions. We are focusing specifically on the contrast between two extremely different cultures: Peruvian and Japanese. From the survey based on stimuli varying in the proportion between chest, waist, and hips, the results indicate the importance of chest-to-hip ratio and waist-to-hip ratio in the attribution of gender to robots.
Comment on Tompalski et al. Combining Multi-Date Airborne Laser Scanning and Digital Aerial Photogrammetric Data for Forest Growth and Yield Modelling. Remote Sens. 2018, 10, 347
Authors: Vauhkonen Jari
Published: September 2018

Tompalski et al. (2018) propose “template matching” as a (required) intermediate step to use remote sensing-based predictions of forest attributes as inputs of the Growth and Yield Projection System (GYPSY) for the simulations of forest stand dynamics in Alberta, Canada. Yet, the feasibility of the approach can be criticized for many points that call for experimental verification. The approach cannot be fully replicated based on the description of the paper. Nevertheless, an experimental implementation with synthetic data indicates that the quality of the projections may vary considerably depending on parameter assumptions for the templates, and the projections may include discontinuities between the observed and projected forest attributes. The approach is poorly motivated given that the effects described above are largely avoidable, if the underlying GYPSY models are run without the template matching step. The R-codes used for the analyses are provided as supplementary data for an interested reader wishing to evaluate the conclusions made above. A semantic analysis indicates further problems with multi-date data on a wall-to-wall grid. The projections obtained by template matching should be exposed to criticism for their realism and benchmarked against other approaches prior to using template matching as proposed by Tompalski et al.
An Exploration of Circular Economy Practices and Performance Among Romanian Producers
Authors: Botezat Elena Aurelia , Dodescu Anca Otilia , Văduva Sebastian , Fotea Silvia Liana
Published: September 2018

Economic growth is the mandate of the global economy and with our planet’s population poised to reach 10 billion people, economists are searching for sustainable economic growth approaches that do not increase raw materials consumption nor deplete and damage our environment. This mandate is the heart of the Circular Economy (CE), a challenge to theoreticians and practitioners alike to continue global economic growth, but with fewer resources and protective methods for our environment. The European Union (EU) economies were early adopters of CE and are now demanding similar adoptions from its recently integrated members from the East. Romania is one of the laggard states in this transition, given its heritage and lack of economic sophistication. Our paper identifies the practices and performance of Romanian producers regarding the implementation of the CE principles, so future recommendations can be formulated. In surveying the Romanian firms, we applied a cluster analysis based on their level of green-oriented supply chain cooperation (GSCC) practices. The respondents were grouped into two clusters: “low green-oriented supply chain cooperation (GSCC) scorers” and “high green-oriented supply chain cooperation (GSCC) scorers’. The results suggest that cluster membership partially influence CE practices and fully influence CE-targeted performance.
PUBLIC SECTOR WAGE PREMIUM AND OUTPUT VOLATILITY IN THE EUROPEAN UNION
Authors: Vilerts Karlis
Published: September 2018

This study seeks to uncover the role played by the public sector wage premium in explaining the output volatility. Furthermore, the study also explores the factors that might substantiate the cross-country differences in the volatility of the public sector wage premium. Using cross-sectional regression analysis for the European Union countries, the findings indicate that more volatile public sector wage premium is associated with higher fluctuations in the private sector employment and less stable growth. Findings also suggest that volatility of the public sector wage premium tends to be larger in countries with smaller governments and in countries where collective bargaining is the predominant regime for public sector wage setting.

Assignment of Virtual Networks to Substrate Network for Software Defined Networks
Authors: Nasiri Ali Akbar , Derakhshan Farnaz
Published: September 2018

Assigning multiple virtual network resources to physical network resources, called virtual network embedding (VNE), is known to be non-deterministic polynomial-time hard (NP-hard) problem. Currently software-defined networking (SDN) is gaining popularity in enterprise networks to improve the customizability and flexibility in network management service and reduced operational cost. A central controller in SDNs is an important factor that we need to take care of when we want to assign virtual networks to physical resources. In this work, we address virtual network embedding problems for SDNs. Indeed, our objective is to propose a method to assign virtual networks in the substrate network with minimum physical resources, and also minimizing delays between the virtual network controller and the switches in the virtual network. Our proposed algorithm considers the link and node constraints such as CPU and bandwidth constraints which is necessary to consider when we try to solve virtual network embedding problems.

Published: September 2018

The expenses in the sustenance of IT investments has become a major ledger item in businesses to the extent that in some cases business priorities had to be changed for sustaining IT systems. Cloud computing, a disruptive technology, is changing the sustenance model with on-demand and metered service approach. However, the adoption of this technology has not been consistent across sectors due to fear on loss of control and changes required in application development and deployment. Authors propose KIET (Knowing, Initiating, Evolving and Transforming) framework based on diffusion theory for adoption of cloud computing in organizations that have strong regulatory framework. Authors implemented the proposed framework on the Indian Banking sector, with majority of the banks being in the public sector. After the implementation of the framework, 49.4% of the banks have adopted cloud computing and another 27.8% of the banks have started the initial steps for adoption.
A Novel ‘Game Design' Methodology for STEM Program
Authors: Viswanathan Shekar , Radhakrishnan B.
Published: September 2018

A novel approach to teaching concepts using game design in the graduate sustainability and engineering management programs is illustrated. These student-built games tied to demonstrate the course learning outcomes (CLOs) were tested in a classroom environment. This pilot study's impact on student learning, motivation, creativity, engagement, innovation, team interactions, and instructor leadership, and its contribution towards the achievement of CLOs were assessed in multiple courses. The results from this pilot study involving students indicated that the game design, creation, and play is an effective and innovative pedagogical tool that could promote student engagement, motivation, critical thinking, and learning skills with minimal educational tools. In addition, this innovative teaching tool could help change the declining and waning interest in STEM+ programs at the graduate level.
Real-Life Contexts in Learning Games
Authors: Moseley Alex
Published: September 2018

The use of real contexts in learning has been of central interest to educational developments such as experiential learning, case studies, work placements and simulations. They centre around the benefits of putting students in realistic situations, using real tools to solve real/realistic problems. A growing number of learning games are making use of context in this way: initially focused around serious games (many close in character to simulations) and most recently distilled into immersive and pervasive games, which mix real and imagined contexts for apparently deep learning experiences. This article reviews the existing literature around the use of context in learning, considers the applicability to learning games, and proposes new theoretical developments through the consideration of four models for the integration of context into learning experiences, based on a typology of existing contextual learning experiences and games. To illustrate the models and begin to strengthen the typology, a number of existing case studies are referenced, and further research needs highlighted.
Modelling the Dynamics of Cow-Calf Dyadic Behavior
Authors: Macedo de Toledo Luciandra , Fernandes Thayná Barcelos , Paranhos da Costa Mateus José Rodrigues , Ambrósio Luis Alberto
Published: September 2018

The dynamics of the first suckling is critical for the formation of the complex cow-calf dyad system, where interactions occur among animals and natural and anthropic environments. In this study, the system dynamics method was applied to build conceptual and computational models to better understand the dynamics of dyadic behavior and its interactions with the environment. The model showed that dyadic behavior is manifested by reinforcing feedback loops in which the calf stimulates the cow's maternal functions, which in turn results in caring stimuli towards the calf. Moreover, ecological factors affect the performance of the animals' behavioral system by influencing the rate of direct events for both, cow and calf. The cow-calf dyad model can be used in silico experiments involving animal behavior, which allows computational verification of dynamic ex-ante hypotheses in vivo experiments, thus reducing costs and honoring the ethical principle of minimizing the experimental use of animals.
Approaches on Physical Education Management and Sports Lessons
Authors: Marin Finichiu
Published: September 2018

Physical and sports education, as an institutionalized activity, involves choosing from the multitude and variety of exercises of the most effective and appropriate methods and forms that are based on perceptions, pedagogical, physiological and hygienic criteria according to age, sex and educational objectives. An unmistakable reality in the life of the university youth, physical education activity involves a multitude of manifestations and a large number of gifted students, willing to advance their physical condition, motor capacities and motor experience in current and systematic practice of the physical education lessons or through the organization system of the student sporting competitions. The practice of exercising has as its objective, regardless of the place, the way or the methods used, the learning, formation, consolidation or improvement of the concerned skills and motor skills. Physical and sport education addresses predominantly the physical education of the human body, but also establishes social links and culture between the participants. Physical and sport education lessons appear in different forms of organization, contributing to the increase of its emotional character, which in turn determines the development of creativity, the spirit of self-denial, of struggle, and of the team.
Review of school vision screening guidelines
Authors: Metsing Ingrid T. , Hansraj Rekha , Jacobs Wanda , Nel Elsabe W.
Published: September 2018

Background: Vision screenings are important in identifying visual anomalies likely to disrupt the physical, intellectual, social and emotional development of children. School health services globally include vision screenings, complementing a variety of associated screening services.Aim: This review article provides evidence for content, provision and efficacy of the vision screening services for children of school-going age and reports on the current practice of children’s vision screenings worldwide including in South Africa.Methods: Studies were identified from PubMed, Ebscohost and Science Direct with the search terms utilised during the selection of electronic articles and journals for the review. The target population includes children of school-going age from 6 to 19 years without previously known conditions associated with visual anomalies and learning-related problems. The quality of vision screening programmes and policies for the school-going age children in different countries were evaluated using Wilson and Jungner criteria.1Results: Vision screening programmes worldwide appear to support comprehensive vision screening methods among pre-schoolers (from birth to ≤ 6 years vs. children of school-going age). The development of vision screening procedures in some countries in the United States of America (USA) was found to be grounded on epidemiologic findings and principles. These may have contributed towards the formulation of national vision screening guidelines for pre-schoolers that supported the detection of amblyopia and its associated conditions such as strabismus, anisometropia and myopia. School-going children’s vision screenings are not supported worldwide as research has shown that there is lack of benefits for detecting other visual anomalies such as vergence and accommodative dysfunctions. This is despite evidence provided by the literature reviewed that an association exists between prevalent accommodation and vergence dysfunctions including poor ocular motilities and poor near-vision, among children of school-going age with poor academic performance.Conclusion: The guidelines worldwide support school vision screenings, especially for the pre-schoolers by the school health nurses, with other programs having considered the teachers, optometrists or orthoptists as the appropriate personnel to conduct the school vision screenings. There is still a need for the effectiveness of the school vision-screening programmes to be investigated related to the importance of detecting convergence and accommodative dysfunctions for the school going age children.

Longitudinal Strain Versus Exercise Treadmill Testing in Chronic Stable Angina
Authors: Bala Renu , Iyer V. Ramnath , Dash Prabhat Kumar , Sola Srikanth
Published: September 2018

Background:

Longitudinal strain analysis has been shown to be useful in patients with acute coronary syndromes and in stress echocardiography. The objective of this study is to identify the incremental diagnostic value of longitudinal strain analysis at rest, when added to routine treadmill testing (TMT), in identifying the presence of coronary artery disease in patients presenting with chronic stable angina (CSA).

Methodology:

We conducted a prospective study in which adult patients presenting with CSA and normal systolic function were enrolled. All patients were examined by 2-D echocardiography, longitudinal strain analysis, TMT, and either conventional coronary angiography and/ or coronary computed tomography angiography.

Results:

We enrolled a total of 150 subjects (54±7.8 years, 63% male). The sensitivity and specificity of TMT was 60.2% and 65.5% respectively. In comparison, global longitudinal strain (GLS) alone had better sensitivity (72.7%) and specificity (74.2%). Post-systolic shortening (PSS) had similar sensitivity for early detection of significant CAD. The combination of TMT and GLS provided the best overall diagnostic accuracy with a sensitivity of 85.4% and specificity of 87.5%, respectively. The optimal cut off for GLS for identification of coronary artery disease was −17.75%.

Conclusions:

In patients presenting with chronic stable angina and normal systolic function, global longitudinal strain and post systolic shortening assessed at rest have excellent diagnostic accuracy for coronary artery disease. Longitudinal strain analysis is superior to conventional TMT and adds to its diagnostic performance.

Role of eyewall and rainband eddy forcing in tropical cyclone
intensification

Published: September 2018

Abstract. The fundamental mechanism underlying tropical cyclone (TC) intensification may be understood from the conservation of absolute angular momentum, where the primary circulation of a TC is driven by the torque acting on air parcels resulting from asymmetric eddy processes, including turbulence. While turbulence is commonly regarded as a flow feature pertaining to the planetary boundary layer (PBL), intense turbulent mixing generated by cloud processes also exists above the PBL in the eyewall and rainbands. Unlike the eddy forcing within the PBL that is negative definite, the sign of eyewall/rainband eddy forcing above the PBL is indefinite and thus provides a possible mechanism to spin up a TC vortex. In this study, we show that the Hurricane Weather Research & forecasting (HWRF) model, one of the operational models used for TC prediction, is unable to generate appropriate sub-grid-scale (SGS) eddy forcing above the PBL due to lack of consideration of intense turbulent mixing generated by the eyewall and rainband clouds. Incorporating an in-cloud turbulent mixing parameterization in the PBL scheme notably improves HWRF's skills on predicting rapid changes in intensity for several past major hurricanes. While the analyses show that the SGS eddy forcing above the PBL is only about one-fifth of the model-resolved eddy forcing, the simulated TC vortex inner-core structure and the associated model-resolved eddy forcing exhibit a substantial dependence on the parameterized SGS eddy processes. The results highlight the importance of eyewall/rainband SGS eddy forcing to numerical prediction of TC intensification, including rapid intensification at the current resolution of operational models.

Published: September 2018

Abstract. Compared to the other continents and lands, Antarctica suffers from a severe
shortage of in situ observations
of precipitation. APRES3 (Antarctic Precipitation, Remote Sensing from
Surface and Space) is a program dedicated to improving the observation of
Antarctic precipitation, both from the surface and from space, to assess
climatologies and evaluate and ameliorate meteorological and climate models.
A field measurement campaign was deployed at Dumont d'Urville station at the
coast of Adélie Land in Antarctica, with an intensive observation period
from November 2015 to February 2016 using X-band and K-band radars, a snow
gauge, snowflake cameras and a disdrometer, followed by continuous radar
monitoring through 2016 and beyond. Among other results, the observations
show that a significant fraction of precipitation sublimates in a dry surface
katabatic layer before it reaches and accumulates at the surface, a result
derived from profiling radar measurements. While the bulk of the data
analyses and scientific results are published in specialized journals, this
paper provides a compact description of the dataset now archived in the
PANGAEA data repository (https://www.pangaea.de,
https://doi.org/10.1594/PANGAEA.883562) and made open to the scientific community to
further its exploitation for Antarctic meteorology and climate research
purposes.
Nuevo marco legal para el reconocimiento como organización de productores de frutas y hortalizas de entidades jurídico-empresariales
Authors: Cañabate Pozo Rosario
Published: September 2018

La necesidad constatada de mecanismos de integración y de concentración de la producción en el sector agroalimentario aconseja reflexionar sobre la peculiaridad de las Organizaciones de Productores de Frutas y Hortalizas (en adelante OPFH), a raíz de la publicación del Real Decreto 532/2017, de 26 de mayo, por el que se regula el reconocimiento y funcionamiento de las Organizaciones de Productores del sector de Frutas y Hortalizas, con el que se adapta nuestra legislación al nuevo marco normativo de la Unión Europea. Dichas OPFH pese a que proporcionan múltiples ventajas, tanto para los productores de frutas y hortalizas como para la ordenación del mercado, sin embargo, no han logrado todavía el éxito esperado.Del nuevo marco legal, y como objeto principal de estudio, se analizan los elementos vertebradores para su reconocimiento como OPFH destacando sus principales novedades, así como las carencias presentes en el mismo. En parte, tales carencias pueden considerarse motivadoras de la falta de consolidación plena de la figura, por lo que se ofrecen propuestas de mejora al recién instaurado régimen jurídico de las OPFH. En todo caso, las cooperativas se erigen como una forma jurídica muy adecuada para el logro de los objetivos asociados a la producción y comercialización en común por parte de los productores de frutas y hortalizas, como finalidad básica y esencial de las OPFH, aunque otras formas jurídicas de organización empresarial como las Sociedades Agrarias de Transformación (en adelante SAT) y las sociedades mercantiles puedan ser reconocidas, igualmente, como OPFH.

Introduction:

Socioeconomic factors such as poverty may mediate racial disparities in health outcomes after total hip arthroplasty (THA) and confound analyses of differences between blacks and whites.

Methods:

Using a large institutional THA registry, we built models incorporating individual and census tract data and analyzed interactions between race and percent of population with Medicaid coverage and its association with 2-year patient-reported outcomes.

Results:

Black patients undergoing THA had worse baseline and 2-year pain and function scores compared with whites. We observed strong positive correlations between census tract Medicaid coverage and percent living below poverty (rho = 0.69; P < 0.001). Disparities in 2-year Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) pain and function were magnified in communities with high census tract Medicaid coverage. For blacks in these communities, 2-year WOMAC function scores were predicted to be −5.54 points lower (80.42 versus 85.96) compared with blacks in less deprived communities, a difference not observed among whites.

Conclusion:

WOMAC pain and function 2 years after THA are similar among blacks and whites in communities with little deprivation (low percent census tract Medicaid coverage). WOMAC function at 2 years is worse among blacks in areas of higher deprivation but is not seen among whites.

The Relationship Between Non-Territorial Minority and Territorial Local Self-Government // Odnos između neteritorijalne manjinske i teritorijalne lokalne samouprave
Authors: Đurić Vladimir , Vranješ Nevenko
Published: September 2018

This paper deals with the relationship between non-territorial minority and territorial local self-government. In many countries where non-territorial minority arrangements exist, they are established at the local level, which opens issues of the organizational structure and ways of their constitution, legal position, powers and relations between such bodies and local self-government bodies. The conclusion is that such bodies, unlike local authorities, do not have a complete representative character and that there are inherent limitations to the powers that can be assigned to them, which is particularly relevant for regulatory powers.

They were systematized for the first time in a special group called: “Criminal offenses against legal traffic” according to the object of their criminal protection. Depending on the type of documents: private, public or official, different forms and types of manifestation of these crimes are often distinguished, which often represent the means or means for the commission of others, primarily commercial or official (corruption) crimes, or for their concealment and difficult proof . In this paper, from the aspect of legislation, legal theory and case law, the concept, elements, characteristics and forms of manifestation of certain criminal offenses against legal traffic in the Republic of Serbia are analyzed.
Tax (Un)Certainty: From Axiom of Taxation to Dimension of Tax Policy Design // (Ne)određenost poreza: od aksioma oporezivanja do dimenzije dizajna poreske politike
Authors: Antić Dinka
Published: September 2018

Principle of tax certainty belongs to legal-technical principles of taxation. It requires that the tax paid by tax payers should be certain, not determined arbitrary. Application of principle of tax certainty is of great importance not only for tax administration because of predictable collection of revenues, but also for taxpayers due to minimising cash flow risks and realization of planned business activities. Classical financial theory considers principle of tax certainty as axiom that should not be explained additionally. However, its application in modern states is jeopardised, since tax systems have become more complex, not only in the sphere of legislation, but also in the field of implementation of tax laws. In the era of globalisation and expansion of cross-border business, taxpayers are facing with problem of tax compliance in more than one jurisdiction, and tax administrations with problem of determination of proper tax treatment. Tax uncertainty seriously affects liquidity, business and business strategies of taxpayers, and, at the macro level, investment, trade and revenue collection. Modern financial flows request a redefinition of principle of tax certainty and an achievement of the balance between tax certainty and desirable degree of tax uncertainty, which is needed for implementation of tax reforms and greater flexibility of tax policy, as strong instrument in the time of economic crisis.

Until the beginning of the twentieth century the reform of criminal procedural laws in Bosnia and Herzegovina from the decision of the public prosecutor to reject the criminal complaint and to give up the prosecution during the investigation, which he was dissatisfied with, the injured party could be protected by peicing criminal prosecution. The prosecution investigation was accepted by the reform. The concept of the injured party as a subsidiary prosecutor has been abandoned and for the first time we received the complaint as a new legal remedy against the orders of the public prosecutor on non-implementation and suspension of the investigation. Although a significant legal remedy, it is relatively rare and superficially addressed in our professional literature. Some issues were raised. The issue of its effectiveness is particularly questioned, ie whether it is an appropriate replacement for an earlier decision by which the injured party had the right to take over prosecution. In order to respond to this, but also some other allegations, the author conducted a comprehensive survey that included complaints against orders for non-implementation and suspended investigations in the District Public Prosecutor’s Office in Banja Luka in the period from 2011 to 2017. Reviewing this issue should contribute to a better understanding of the complaint, its more correct application, and new legal solutions that better suit our conditions, practical needs and theoretical settings.

The Influence of Modern Technical Systems in Vehicles on Road Safety
Authors: Glamočić Ljubo
Published: September 2018

A vehicle is a very complex technical system with several aspects. The basic purpose of each motor vehicle, is its primary goal to ensure the safety of the vehicle and, therefore, the safety of all traffic users. In order to achieve the basic goal, in the latest motor vehicle engineer development, during the development itself to the ultimate serial production, considerable attention is paid to the development and improvement of technical systems that help and improve vehicle management, and improve the control of the dynamic movement of vehicles. The ABS system (Anti-lock Braking System) is a precursor to the development of these systems, based on which a whole spectrum of active management systems has been developed. There is an overview of positive impacts of some system on the vehicle safety.  Influence of the system of the active safety of traffic is presented through the correlative interaction between the number of traffic accidents with light bodily injuries, number of the light injured persons and number of vehicles possessing ABS and/or ESP system and number of traffic accidents and their consequences in the Republic of Srpska. The results showed that there is a strong correlation between the number of traffic accidents with light bodily injuries, number of light bodily injuries and number of vehicles possessing ABS and/or ESP system. Furthermore, the results showed that the increase of number of the registered vehicles increases the percentage of vehicles possessing the mentioned systems. Safety of vehicles is a very important factor of the traffic safety. Decrease of the average age of the fleet contributes to the great extent to the decrease of a number of the traffic accidents and their consequences.

Wild cyclamen tubers (Cyclamen purpurascens Mill.) (mountain Kukavica, Southeast Serbia) were used as material for extraction in this study. Aqueous extract was obtained by reflux extraction on boiling temperature with hydromodulus 1:20 m/v during 180 minutes. The total phenolic content was determined spectrophotometrically by the method of Folin-Ciocalteu, and the total flavonoids content by method with AlCl3. The antioxidant activity of extract was investigated spectrophotometrically by DPPH and ABTS test. Disc-diffusion method was used for antimicrobial activity investigation on the following pathogenic microorganisms: Staphylococcus aureus, Bacillus cereus, Enterococcus faecalis, Pseudomonas aeruginosa and Klebsiella pneumoniae. The content of total phenols was 8.27 mg GAE/g dry extract while the total flavonoid content was 11.51 mg RE/g dry extract. The extract concentrations required to neutralize 50% of the initial concentration of DPPH radicals (EC50) after 20 minutes incubation and immediately after adding DPPH radical solution were 0.413 and 2.0 mg/ml, respectively, while concentrations of extract required to neutralize 50% of the initial ABTS radicals concentration is 0.743 mg/ml. The extract showed the highest antimicrobial activity on bacteria Staphylococcus aureus. The presented results indicate that cyclamen tubers extract is a potential source of natural antioxidants and antimicrobial agents.

Published: September 2018

Noise pollution, as a major environmental problem, is present in Banja Luka. The measured values exceeded the level of noise allowed, which is a great problem. Evaluation of the noise levels was carried out in the streets in the area with health institutions. Objectives of this research were to evaluate the environmental noise pollution in the City of Banja Luka due to traffic noise and to compare the measured noise levels in the city with legislation and to establish the connection between noise and the number of vehicles. Correlation between the noise level and number of vehicles was positive and significant during the study period (r=0.89). It is confirmed that, with the increase of the number of vehicle, the noise level increases, i.e. the decrease in the number of vehicle decreases the noise level.

Aim is to analyze environmental load with aluminium packaging, used in food industry. especially with aluminium cans. LCA shows origin of materials, aluminium production, as basic materials, emission to air, water and soil and quantitz of wasting materials, as a result of production of 1000 aluminium cans.This study includes:raw material for aluminium productionaluminium productionaluminium cans productionusage and recycling of aluminium cans.For this study we gathered data for fuel and energy consumption, amount of raw materials, products and byproducts, emission to air, water and soil, and a quantity of waste material. Within a metode of calculation of influences to environment as indicators was used:global warming (kg CO2-ekv.), eutrophication (kg P-ekv), acidification (kg SO2-ekv.), ekotoksicity (kg 1,4 DB-ekv.), reserves shortage of nonrenewable resources (kg), water consumption (kg), toksicity for humans (kg 1,4 DB-ekv.), oyone layer destruction (kg R11-ekv.) soil occupation (m2·god.). LCA model is made by GaBi 4 software system (verzion GaBi 4.3) [8].In order to have relevant estimation of influence to environment, we defined cut-off proces value. In this case as cut-off value was used value of weight ratio less than 5%, and in that case proces disregarded.

This paper investigates the impact of accidental release of chlorine gas in surrounding areas consequences of chlorine gas leak studying the negative effects on both the environment and individuals. Chlorine and its consequences have a far more reaching effect in society that one may have imagined. The ALOHA software has been used in this paper to modelling of chlorine release. The modelling was performed for an accidental release of 3.373 tons chlorine gas from unsheltered single storied for one hour. For a typical average atmospheric condition in location, this accidental chlorine release would cause a red zone of 3.0 kilometres (AEGL-3=20 ppm), orange zone of 7.1 kilometres (AEGL-2=2 ppm) and yellow zone stretching to greater than 10.0 kilometres (AEGL-1=0.5 ppm) to downwind from the source.
