http://ijaers.com/ Open Access international Journal to publish research paper en-us October 2018 The problem of signalized intersection is caused by the traffic volume continually increasing each year, automatically contributing high delay and frequent congestion and One indicator of traffic congestion at the roundabout is a decrease in vehicle speed [1]. Today’s operated traffic lights have not yet capable of overcoming congestion which often occurs in the peak hours. The existing condition on intersection has not yet been able to accommodate the populous traffic volume; it can be seen from each of intersection foot while experiencing the vehicles daley. The imprecised existing condition on the Antasari intersection in Banjarmasin, is seen from the 4-phase control with the cycle time at 177 seconds, the degree of saturation is ≥ 0.85, and the delay is ≥ 60 seconds; making it categorized as the intersection with F-level of service (the worst). This research aims to analyse the existing condition of the Antasari intersection’s performance, and to obtain some handling alternatives of Antasari intersection, with some approaches. To increase the performance of Banjarmasin’s Antasari intersection, some handling alternatives are executed, such as: the control of Cycle Time, the control of phase direction (phase simulation), and the phase change by using KAJI program. Based on the field data, obtained the performance of Banjarmasin’s Antasari intersection in existing condition: the cycle time is 177 seconds, degree of saturation is 2,879 or ≥ 0.85, delay is 963 seconds/pcu or ≥ 60 seconds/pcu, and the worst service level (F-level). In some intersection handling alternative results, there comes one alternative that is able to increase the intersection performance: through the phase simulation stages, with the phase adjustment of the north – south of KolonelSugiono streetamd the east – west of PangeranAntasari street, then the acquired results of the Service Level-C are: the delay value (D) is 23.33 seconds/pcu or ≤ 25 seconds/pcu, the degree of saturation (DS) is 0.671 or ≤ 0.85, and the cycle time (CT) is 67 seconds or ≤ 80 seconds. http://ijaers.com/detail/evaluation-and-performance-improvement-of-antasari-intersection-banjarmasin-city/ M.

Diet plays a key role in the etiology of breast cancer and breastfeeding is associated with a lower incidence of breast cancer. On the other hand, the improvement of the therapeutic properties of bioactive compounds through their incorporation into microcarriers is an important strategy in obtaining new therapies, since cyclical changes in concentration are eliminated; there is biological availability of the compound as well as the reduction in toxicity, number dose and suppression of adverse reactions. Studies using hormones such as melatonin extracted from human milk adsorbed onto polyethylene glycol (PEG) microspheres showed that the controlled release of this compound was able to reduce viability and induce apoptosis in MCF-7 cell lines. Colostrum differs from most of the secretions because it contains viable leukocytes during the first days of lactation with a quantity and activity comparable to blood leukocytes, and has several defense components such as antibodies and hormones, such as melatonin (MLT). This review details the influence of the soluble and cellular components present in human colostrum, such as the MLT hormone, as the modified release systems influence the action of MLT and the possible mechanisms involved that contribute to the hypothesis of reduction of breast cancer in women who breastfed. http://ijaers.com/detail/melatonin-bioengineered-a-new-possible-strategy-for-treatment-of-breast-cancer/ Rubian Trindade da Silva Fernandes, Aron Carlos de Melo Cotrim, Eduardo Luzía França, Adenilda Cristina Honorio-França, Inês Aparecida Tozetti http://ijaers.com/uploads/issue_files/2-IJAERS-SEP-2018-39-Melatoninbioengineered.pdf Objective: To analyze the quality of groundwater potentially impacted by nitrate (NO3-), before and after the flooding of the Madeira River, in two urban areas of Rondônia on the Brazil / Bolivia border.

Method: This work made use of research in secondary bases as well as in primary bases. The tabulation of qualitative and quantitative data was performed in Excel (2010) and for their processing performance index construction purposes were calculated following the factorial analysis techniques presented by Hair et al. [19] Santana [20, 21]; and Choi [22]. For this, we made use of the statistical tool SPSS (Statistical Package for Social Sciences) for the construction of the indices of social capital. The correlation analysis process was done in Excel. results: It was observed that the capital reached regular levels in Guajará-Mirim neighborhoods not observable, so correlations between the studied parameters, however, it needs to be further studied as factors such as the flooding of the Mamore river may have interfered in any way in the implementation process of the field survey to the residents of the city. It became clear that the municipality of Guajará-Mirim suffers from serious social problems and that most problems are correlated with the increase in alcoholic beverage market in the city and use drugs. However, was not observed as the institutional arrangements are dealing with this problem, that is, as public bodies are relating to discuss actions for concrete solutions to this evil that plagues large portion of the population of Guajará-Mirim, mainly young teenagers residents of Guajá-Mamim.

In this paper, a characterization of a copper powder for heat pipe wick applications was experimentally done. The copper powder manufacturing method was atomization. This metallic powder was characterized by Scanning Electron Microscopy (SEM), X-Ray Fluorescence Spectrometry (ED-XRF), and Laser Diffraction Granulometry. As a result, the purity and the shape are compatible with the powder manufacturing method and great for wicks. Also, the copper powder has a unimodal distribution that is excellent for capillary structures. http://ijaers.com/detail/characterization-of-a-copper-powder-for-heat-pipe-wick-applications/ Guilherme Antonio Bartmeyer, Larissa Krambeck, Robson Couto da Silva, Davi Fusão, Thiago Antonini Alves http://ijaers.com/uploads/issue_files/7-IJAERS-SEP-2018-38-Characterizationofa.pdf The study with the penitentiary agents that work in the female prison system of Porto Velho aimed to analyze the level of job satisfaction and the level of mental suffering of these workers. It is a descriptive and cross-sectional study. This study was performed with 34% of the penitentiary agents who carry out their activities at the Porto Velho Women's Penitentiary, Rondônia. For the data collection, three structured instruments were used: The Sociodemographic Questionnaire; the Self-Report-Questionnaire (SRQ-20), and the Occupational Stress Indicator (OSI), measured using a Likert scale. Satisfaction in the work had similar indexes to those found in the literature, presenting the highest proportion in the intermediate variables, that is, their higher frequencies are in the range of some dissatisfations, with 40%; and 35% with some satisfactions. The highest level of dissatisfaction is in the variable to the form by which changes and innovations are implemented, with 55%. The results showed that the prison staff had lower psychiatric disturbances (19.59%), in the following order of determination: decreased energy (23.33), depressed mood (23.33%), somatic symptom (21.25%), other symptoms of SRQ-20 20%) and depressive thoughts (10%), considered as indicators of evidence of mental suffering.

The heat transfer, over the course of laser-metal interplay, has a great importance in metal forming. In this study, different types of materials were investigated in order to designate the temperature distributions inside material and on the material surface versus the thermodynamic properties of the material used and then the temperature distributions obtained from the analysis were compared each other. In addition, the heat transfer is occurring during the interaction of the laser power of 1.1010 W/m2 and 5.1010 W/m2 with laser power intensity in two main groups using different materials these are steel, nickel, tantalum and titanium, and numerical results are obtained using the finite-difference method. In the first step, a solution is obtained by electron kinetic theory according to the basic heat transfer. In the second step, since heat convection is formed after material has reached the melting point. Using electron kinetic theory model for convection solutions have been obtained. Moreover, the temperature distribution that occurs during the laser metal interaction was studied by variation of the time chart and the material depth. As a result of the study, material's surface at the correct temperature of liquid phase change material and increased depth in the direction perpendicular to the electro-kinetic theory approach is further demonstrated by the decrease in the first manner and then remains constant in exponential phase change temperature. In addition to this the analysis results, the substrate temperature increases, the change in phase in the material becomes smaller and smaller. http://ijaers.com/detail/analysis-of-heat-transfer-in-the-material-during-pulsed-laser-metal-interaction-by-using-kinetic-theory/ Yıldız Koç, Ertuğrul Baltacıoğlu http://ijaers.com/uploads/issue_files/9-IJAERS-SEP-2018-43-AnalysisofHeat.pdf The step response characteristics of first and second order systems are well known. On the other hand, the step response of fractional order systems (FOSs) with 2-term fractional denominator is like those of first and second order systems. But there are important differences between the two types of characteristics. Considering the step response, the behavior of simple FOS with a denominator polynomial having unity term and the other involves fractional power is investigated in this paper comparatively with 1st and 2nd order systems.

The Scientific Approach includes “5M” activities namely observing, questioning, experimenting, associating, and communicating. In implementing this approach in Indonesia, the teachers only use two kinds of books: teacher’s and student’s book; as a reference in the process of learning. One of the learning methods with the scientific characteristics is the Project Based Learning. Project Based Learning is a learning method that uses problems, as the first step to collect and integrate new knowledge, which is based on the real-life experience. The purpose of this research is to improve the students' analytic skill and responsiveness with the application of Scientific Approach-based learning using Project Based Learning Model. In the development of Scientific Approach-based resources with Project Based Learning model to improve the students' analytic skill, it was found that the average point of 3 validators for the lesson plan (RPP) was 4.66%, for the students’ worksheet (LKDP) was 4.6% and for the achievement test (THB) was 4.66%; which have met the criteria of valid.

Recently the scope of legged locomotion changed from static stability to dynamical stability, in which the dynamics of the system plays an important role in the development of control algorithms that have as a main goal the construction of a stable limit cycle. This article projects a periodic control for trot without the air phase for a quadruped though the multiple shooting method with Hermite-Simpson direct collocation. The algorithm was first tested in a monopod where the control for hopping and forward hopping was searched, such that the optimization occurred after finding the periodic gait and for each case the stability of the control was determined through the Floquet Multipliers from Poincare's map. The quadruped system could not be wholly analyzed because the search for the periodic gait failed for the initial estimation, leaving this analysis for future researches. http://ijaers.com/detail/search-and-optimization-of-the-periodic-gait-of-leg-locomotion-systems/ Nicolas Ives Roque Pacheco, Pedro Américo de Almeida Magalhães Júnior, Júlia Maria de Carvalho Vale http://ijaers.com/uploads/issue_files/12-IJAERS-SEP-2018-47-Searchand.pdf In this article we explore the transformation of a family company into an anonymous society, or rather, a joint-stock company, and the importance of the leader in this transformation process.

The developed technology permits to widen raw stuff basis of producing artificial porous aggregates for lightweight concretes. The investigations have demonstrated that granulated slags which are a by-product and are obtained through making non-ferrous metals, can be utilized as a basic starting raw material for manufacturing an artificial porous aggregate. From the results of the investigations expansion intervals of a mass based on the studied slags of metallurgical plants are determined. The technology of obtaining an artificial porous aggregate with the prescribedphysico-mechanical characteristics has been worked out. The main physico-mechanical characteristics of the produced aggregate have been studied. It has been revealed that the obtained artificial porous aggregate meets the requirements of the acting standard GOST 9757-90 “Gravel, Crushed Stone and Sand, Artificial Porous” by its physico-mechanical characteristics. It is found that the strength of the obtained aggregate 1.5-2.0 times exceeds that of the well-known aggregate- keramzit gravel. Using porous sand lightweight concrete of B7.5-B40 strength class with density of 1100-1600kg/cu.m has been produced on the base of the obtained gravel and high-strength lightweight concrete of strength class B25-B50 with density of 1500-1800 kg/cu.m has been manufactured with the use of dense sand and plasticizing additives. http://ijaers.com/detail/an-artificial-lightweight-aggregate-based-on-non-ferrous-metallurgy-slags/ Huseyn Mammadov, Irada Suleymanova, Tahirov Bahadur http://ijaers.com/uploads/issue_files/16-IJAERS-OCT-2018-1-AnArtificial.pdf Research on Nonlinear Transmission Lines (NLTLs) has long been carried out to produce oscillating pulses. The radiofrequency (RF) pulses generated by the NLTLs can be radiated by antennas connected to the output of the lines. Possible applications of NLTLs as an RF generator include aerospace radars, telecommunications, battlefield communication disruption, and medical devices. There have been relatively few articles that presented experimental results regarding the extraction and the radiation of the RF signal from NLTLs. This article reports the excellent results obtained with a low voltage lumped capacitive NLTL in which oscillations of the order of 230 MHz were produced and radiated using Double-Ridged Guide (DRG) antennas. The RF signal was extracted using a decoupling circuit based on a Chebyshev high-pass filter. The NLTL was evaluated through time domain and frequency domain analyses of the pulsed RF signal measured on a resistive load connected to the output of the line, as well as on transmitting and receiving by antennas. The LT-SPICE model of the line was implemented and the comparison of simulation and experimental results presented a good agreement. http://ijaers.com/detail/study-of-pulsed-rf-signal-extraction-and-irradiation-from-a-capacitive-nonlinear-transmission-line/ Leandro C.

Most of the overhead tanks have a fundamental frequency which includes a series of resonance of greatest earthquake ground motions. It is an operative way to reduce the response of an isolation system used for storage of water tanks under a sturdy earthquake. However, it is problematic to implement in preparation with common isolation bearings The research is directed with study of existing studies in the field of seismic behavior of intz water tank. Base isolation is one of the technologies applied to decrease the consequence of earthquake effect. The principle is to separate the base of the overhead water tank from footing ground. The problematic is taken as Intz water tank design to survive water tank against seismic accomplishment. three categories of base are used to analyses and compare overhead first is manual design of intz water tank with fixed base + response by SRSS and second case is intz water tank with fixed base by sap2000 and Third case with is intz water tank with triple friction pendulum on sap2000.

The use of this technology for EAC/FM is being widely investigated. In the scope of dam safety, the constant analysis of concrete behavior is mandatory, searching for clues of pathologies such as cracks. Cracks are relatively common in concrete structures, nevertheless they need to be surveilled due to the risks they offer. The surveillance of cracks involves exhaustive tasks, and for dams, it consists in the execution of a set of complex tasks that demands access to accumulated data and information. Augmented reality can contribute with the visualization process of this information, diminishing the mental workload demand.

The mechanical system includes two main mechanisms which are rack and pinion gear mechanism and reciprocating four bar linkage mechanism. The rack and pinion arrangement is used to move whole mechanical system up and down for cleaning the cylindrical tank. The rack is fixed on the motor and the four-bar mechanism is attached to the motor shaft. PVC brushes are attached to the ends of the four-bar linkage. Four bar linkage is made in such a way that it can be adjusted according to inside diameter of the tank. When the motor is started the linkage rotates and with the help of brushes, cleaning of wall and base of tank takes place. The purpose of this project is to reduce the human efforts and to avoid the chemical influence on health of person entering the tank for cleaning. In this modern world, cleaning of overhead tanks manually is a tedious job. To overcome this we have aimed at tackling the disadvantages of cleaning overhead tanks, so an automatic system overhead tank cleaning is designed to provide high safety, high efficiency, less time for cleaning and to avoid environmental pollution problems. Purpose of this paper is to clean domestic cylindrical water tank with the help of mechatronics system. The mechatronics system consists of a grooved gear rod attached to two arms with brushes at ends. The two arms are connected to the gear rod by nut. By rotating the gear rod, the up and down motion of the two arms is achieved. The gear rod is rotated with the help of a D.C gear motor. The main grooved shaft is powered by an A.C motor. The motor and the shaft are connected by a rubber belt. The clockwise rotation of the main shaft will make the arms move and vice versa. The whole operation is controlled by a circuit consisting of relay switches, buttons, and PIC microcontroller. The number of times for the operation to repeat can be fed into the circuit. The achievement of this project is reduction of cost and manual labour because there will be harmful diseases for the person who will go inside and it will affect the health as well as the other human being who consumes water from the tank. http://ijaers.com/detail/automatic-overhead-water-tank-cleaning-system-a-review-and-an-approach/ Rohit R.

Its influence on the emergence of other sciences and applications, whose developments in the post-war period contributed to the increased rationalization of modern society are evident. Given this context, this article aims to trace an analytical reconstruction on the philosophical and methodological aspects that mark the history of operations research. Such reconstruction will be developed based on a historical method using bibliography and documents. The refinement of Operations Research techniques was a determining factor for its success, and its methodological and philosophical aspects have revered thinkers such as John Dewey, Churchman, and Capra, who are references to understand modern men's thought. It turns out that World War II was determinant for science in general and more specifically for the great advance of operations research. The achievements of the OR, largely, result from the formation of multidisciplinary groups that allowed the evolution of the area in several directions, providing an interdisciplinary dialogue. http://ijaers.com/detail/philosophical-and-methodological-aspects-of-operations-research-the-evolution-of-an-interdisciplinary-area/ Viviane Hengler Corrêa Chaves, Cristiane Hengler Corrêa Bernardo http://ijaers.com/uploads/issue_files/26-IJAERS-OCT-2018-10-Philosophical.pdf This paper exposes characteristics from an evaluated cover layer (0.6 m height) from the experimental Muribeca landfill of Urban Solid Residues (SUR), located in Jaboatão of Guararapes, Brazil. Through laboratory experiments of suction, grain size distribution, and permeability, those parameters were analyzed based in the existing technical standard Brazilian for this procedure. The soil was studied by the division of a cover layer, after 5 years from its completion, of 0,6m, in depth the upper half (0.1 m to 0.3 m) and lower half (0.4 m to 0.6 m), looking for differences of leaching through the upper to lower part. Therefore, the consequences to be presented from the leaching of the materials, after 5 years of finalization of the landfill, making its permeability increase. Concerning its water retaining, it is the most retained in the upper part, which comprises the compost, with a difference in the order of 7 per cent the superior half to inferior half, retaining the least suction from the surface. Leaching was detected through permeability procedure of worthless difference between upper and lower part of the cover layer. Nevertheless, results revealed the efficiency of the cover layer in retaining the rainwater, offering this layer as an alternative solution for the appropriate waste disposal. http://ijaers.com/detail/suction-water-retention-capacity-and-permeability-assessment-of-compacted-and-unsaturated-cover-layer/ Nayara Torres Belfort, Daniela dos Santos Santana, João Paulo Sá Neves, Antonio Rodrigues de Brito, José Fernando Thomé Jucá http://ijaers.com/uploads/issue_files/27-IJAERS-JUN-2018-25-SuctionWater.pdf One of the greatest challenges facing rural producers stems from the difficulties in accessing markets majority controlled by the major distribution chains. The small quantities under production and the low level of investment capacity ensure that smallholders in particular encounter an asymmetric relationship with the retail sector. The European Union (EU), through means of the Common Agricultural Policy (CAP),has adopted strategies to overcome these obstacles through stimulating farmers to concentrate their own supply through Producer Organisations (POs).These POs, in addition to concentrating supply, also act to improve productivity and guarantee reasonable prices to consumers. The objectives of this article include analysing challenges faced by the concentration of the agricultural product supply chain through a study of POs in Portugal. The research findings arise from analysis of both primary and secondary sources of information. The research techniques applied were documental analysis and holding interviews with six key players. The research results demonstrate how the average level of PO participation in the EU stands at 46% but falls back to 25% in Portugal. The results are also below those presented at the EU level despite accelerated growth taking place in the horticultural sector, which more than doubled its level of participation over the last decade (10% in 2005 rising to 26% in 2014). We conclude that, on the one hand, POs respond positively to the challenges of supply chain concentration; on the other hand, this has lacked the impact necessary to reversing the ongoing rural desertification in Portugal. http://ijaers.com/detail/the-challenges-of-concentration-in-the-agricultural-product-supply-chain-a-study-of-producer-organizations-in-portugal/ Dimas de Oliveira Estevam, Maria João dos Santos http://ijaers.com/uploads/issue_files/28-IJAERS-OCT-2018-17-Thechallengesof.pdf At present, information and communication technology (ICT) impacts every aspect of life. They play essential roles in the workplace, business, education, and entertainment. Changes in working conditions, information management and interchange, educational approaches, learning strategies, academic research, and accessibility of information communication technology are all seen as catalysts for change by many people. ICT in the classroom is crucial for learners to study and establish appropriate 21st-century skills in this digital age. ICT enhances teaching and learning, and instructors must fulfill their role as pedagogical environment designers. ICT enables the teacher to communicate instruction in an appealing and easy-to-understand manner for students at all levels of schooling. Currently, in the Philippines, teaching instructions are becoming more valuable and appealing due to ICT usage. ICTs, such as the world wide web and interactive multimedia, are critical for future education and should be seamlessly incorporated into formal teaching-learning, especially in teacher education institutions. In today's world, information and communication technology (ICT) is critical in education. It uses information and communications technology to support, enhance, and optimize information delivery. Research results show that ICT can improve student learning and better teaching methods. http://ijaers.com/detail/innovative-teaching-learning-process-through-ict-integration/ Bren C.
