http://ijaers.com/ Open Access international Journal to publish research paper en-us December 2017 The construction of knowledge today requires a new posture of the researcher, requires a broader and holistic view, with the interaction of the various areas, both in the expansion and in the deepening in the treatment of complex studies. Thus, the objective of this work is to identify the pedagogical practices for the development of the critical scientific spirit in the student in the learning environment. With this research, it was possible to conclude that with pedagogical practices based on the practice of inter, multi and transdisciplinarity, it is possible to contribute to an autonomous society, transforming tacit knowledge into explicit knowledge to serve as a basic tool for social development, with capacity to share and incorporate new technologies and disseminate them to society to make its economic and social transformation. http://ijaers.com/detail/the-use-of-multidisciplinarity-interdisciplinarity-and-transdisciplinarity-to-develop-the-critical-and-scientific-spirit-in-the-student/ Vanessa Cristhina Gatto Chimendes, Adriano Carlos Moraes Rosa, Yara C. Costa Rocha Miranda, Herlandí de Souza Andrade http://ijaers.com/uploads/issue_files/1 IJAERS-OCT-2017-25-The use of Multidisciplinarity.pdf Tunisia has limited primary energy resources and produces only fossil fuels. The technology of biogas production by anaerobic digestion or biomethanation is very little known and poorly applied in Tunisia. Indeed biogas is very neglected among the main sources of energy in the country. The use of biogas technology can solve a number of ecological and economic problems. Today, its prospects for the future appear promising, justifying the need for a judicious awareness, followed by pilot experiments with a view to the further popularization of biogas technology and its interests. In Tunisia, the poultry sector produces a large quantity of laying inches, abandoned without any recycling or recovery, which can constitute a potential source of an environmental contamination in general, although it is an organic source that can be valued and has important energy and agronomic interests. This study aims to optimize and to follow the experimental biometanation of the poultry litter. Physicochemical and microbiological evaluation of the substrates was carried out. As for the energy side, the anaerobic digestion chosen is in discontinuous (batch), mesophile (35 ° C) and wet (8% DM of digester) mode. The main results show that poultry excreta is rich in organic matter and bacterial load, which favors the production of biogas, in particular with the addition of inoculum and activator. It should also be noted that anaerobic digestion resulted in a decrease in microorganisms and that the activator (especially with 18%) improved the speed of the hydrolysis phase and favored the production of biogas and especially methane. http://ijaers.com/detail/experimental-anaerobic-digestion-of-poultry-droppings-and-microbiological-and-energetic-monitoring-of-the-process-under-study/ I.

In the identification of the physical characteristics, the centers of mass and moments of inertia of the twin rotor parts were identified separately, by means of an easel designed for such task. Still in the identification of the physical characteristics, the equation that relates the applied voltage in the direct current motor with the thrust force produced by the propellers was obtained. The mathematical model of the twin rotor was obtained by means of the identification of the physical characteristics allied to the virtual prototyping with the aid of ADAMS and SolidWorks software. The implemented control system uses state feedback and complete eigenstructure assignment. The ease and usefulness of the proposed methodology was presented through the plant instrumentation, simulation and control in MATLAB/Simulink environment. http://ijaers.com/detail/virtual-prototyping-identification-and-control-of-a-twin-rotor-with-3dof/ Bruno M.

Besides protecting the weld pool and influencing the bead geometry, fluxes also melt in a specific temperature range, refine the weld metal, as well as take part in slag metal reaction before finally being removed as slag. Welding flux constitutes nearly half of the cost in SAW process. Over the years, development of better welding flux compositions in terms of mechanical properties and productivity, which are economically cost effective too, has caught the eye of many researchers. In the present review paper, research work carried out by various researchers in the field of welding flux development has been reviewed. http://ijaers.com/detail/effect-of-flux-in-submerged-arc-welding-a-review/ Uma Gautam http://ijaers.com/uploads/issue_files/8 IJAERS-DEC-2017-9-Effect of Flux in Submerged.pdf The Network Packet Flow is analyzed and defined by the network administers in the company to assure the exact data flow in the networked systems.

In a three-dimensional virtual environment, the features of objects such as shape, color, movement, etc. are digitized and simulated using basic computer graphics techniques. In addition to the above characteristics, objects can contain content which changes in the form of images or text, with diverse information. The problem is that these content should be rendered on the virtual object, so that both the content and the real time of the application can be satisfied. In this paper we present an approach for updating and rendering content on objects in a three-dimensional virtual environment based on GPU architecture. http://ijaers.com/detail/updating-and-rendering-content-on-objects-in-a-three-dimensional-virtual-environment/ Le Anh, Nguyen Trung Kien http://ijaers.com/uploads/issue_files/12 IJAERS-DEC-2017-17-Updating and Rendering Content.pdf The Barremian succession in the present study is represented by the Zubair Formation which the most significant sandstone reservoir in Iraq.The area of study is located in the Southern part of Iraq at the Luhaisand Rachi oil fields, within the Mesopotamian basin. The thickness of the Zubair Formation is about 450 m in the studied area. It is divided into three lithofacies:- The upper unit is composed mostly of shale layers, the middle unit is consists of thick layers of sandstone rocks and the lower ones is consists mainly of Shale with less sandstone layers. These units are characterized by three types of petrophysical features according to total porosity/effective porosity: - High-moderate effective porosity rocks (type I), moderate effective porosity rocks (type II) and low-non pores rocks (type III). The upper unit of theZubair Formation at the Luhais oil field is characterized by two horizons. The first is showing high resistivity-high gamma ray which represents the upper part; while the lower ones is shown low resistivity-low gamma ray. There are two good reservoir horizones with high oil saturation (low water saturation) in this unit at the Rachi oil field and Lu-3 borehole, while at the Lu-12 is appeared as one uncontaneoushorizon. The middle is characterized by two subzones in the southwestern part of Luhais oil field (Lu-12). The upper one characterized by high- moderate effective porosity while the lower one characterized by moderate effective porosity because of presence a low volume of shale. This unit is dominated by low resistivity-low gamma ray with three susbended bands of high resistivity-low gamma ray, these appeared in both studied oil fields. The high percentage of water saturation in this unit caused the lack of clarity of the oil saturation, which appears in narrow bands The lower unit is represented the shale – dominated member of Zubair Formation, with low to non-pores rocks. This appeared in all studied wells. There are limit presences for the high- moderate effective porosity of rock within the sand bands lithofacies appears in these wells. This unit is characterized by alternative the high resistivity-high gamma ray horizon with the low resistivity-low gamma ray horizon as four cycles. There are two good reservoir horizons with high oil saturation (low water saturation) in this unit with a distribution similar to that found in the upper part. From the reservoir geology which represent by property modelling, preparing data, construction of three-dimension clump and scale up for the studied oil fields. The Rachi oil field is appeared the better hydrocarbon saturation compared to Luhais oil field, although the Luhais oil field (Lu-3 and Lu-12) is the best of pertophysicalproperties. This indicates that the Rachi oil field was affected by the structural position as indicated by the model, while the model did not show any structural properties in the field of Lahis. Therefore, the structural and/or stratigraphic positions have the greatest influence on the hydrocarbon accumulation, regardless of petrophysical properties. http://ijaers.com/detail/petrophysical-evaluation-and-reservoir-characterization-of-the-zubair-formation-in-the-luhais-and-rachi-oil-fields-southern-iraq/ Aiad Ali Al-Zaidy, Kamal Salim Mohammed http://ijaers.com/uploads/issue_files/13 IJAERS-DEC-2017-14-Petrophysical Evaluation.pdf Suspended sediment estimation is important to the water resources management and water quality problem. In this article, artificial neural networks (ANN), M5tree (M5T) approaches and statistical approaches such as Multiple Linear Regression (MLR), Sediment Rating Curves (SRC) are used for estimation daily suspended sediment concentration from daily temperature of water and streamflow in river. These daily datas were measured at Iowa station in US. These prediction aproaches are compared to each other according to three statistical criteria, namely, mean square errors (MSE), mean absolute relative error (MAE) and correlation coefficient (R). When the results are compared ANN approach have better forecasts suspended sediment than the other estimation methods. http://ijaers.com/detail/forecasting-of-suspended-sediment-in-rivers-using-artificial-neural-networks-approach/ Bestami Taşar, Yunus Ziya Kaya, Hakan Varçin, Fatih Üneş, Mustafa Demirci http://ijaers.com/uploads/issue_files/14 IJAERS-DEC-2017-18-Forecasting of Suspended Sediment.pdf This paper presents a methodology to facilitate the development of a Fuzzy Logic Controller (FLC). The process is done through the use of model rule base, in addition to the adjustment of the membership functions and the universe of discourse related to the system variables. This adjustment is accomplished by refinement rules similar to those used in a classical control technique. In this way, PID control system designers can use their knowledge of parameter tuning to obtain the desired performance in the Fuzzy system. This knowledge allied to the model rule base contributes to decrease the controller development time. Therefore, as an application of the method, a non-linear model of a submarine is used to evaluate the performance of the FLC. A model rule base developed by MacVicar-Whelan and the basic rules of refinement elaborated by Procyk and Mandani are applied for the development of the FLC. The simulations are performed through MATLAB software and the FLC is developed with the Fuzzy Logic Toolbox. http://ijaers.com/detail/control-of-non-linear-equation-of-submarine-using-pi-like-fuzzy-controller/ Matheus F.

Sport massage has the effect of relieving stress, improving tissue elasticity, and eliminating the buildup of lactic acid. In the general population of Indonesia, Sport massage is considered as the most powerful means for stimulating the decrease of lactic acid inside the muscle. Sport massage with Swedish techniques has major applications in the form of Eflleurage, Petrissage, Vibration, Tapotement, Friction, Shaking in accordance with anatomical of the athlete's body. The type of research used in this study is quantitative research with experimental method that is quasi experiment. Experimental method is a way to express the relationship between two or more variables to understand the influence of a variable on other variables. Based on these methods, the design research used nonequivalent control group design. In the design of this study, the experimental group and the control group were not chosen randomly, thus the subject division in this study using ordinal pairing technique. So from the design can be known correctly the difference from the treatment result given. Author is using E-Views 5 software to test the correlation between the dependent variable and the independent variable.

The mathematical model of the ball and beam is obtained through the equations of Newton-Euler and the equations were linearized. The system is controlled using the hardware-in-the-loop technique with MATLAB/Simulink.It is applied a tracking control system with entire eigenstructure assignment to control the position of the cart. The actuator used is a DC motor, and a PID(proportional, integral and derivative) control is used to perform the angular position control of beam.The simulation results and the experimental results are compared to validate the mathematical model.

Ltd. (ISDEMIR)'s No:1 Blast Furnace Aspiration Concrete Chimneys were examined. These reinforced concrete chimneys were built according to the Russian standard in 1975. For reinforced concrete chimney concrete and reinforcing rebar, Russian Norm standards have been translated into norms that used in Turkey. For years, industrial dynamic effects, occurring in the region through strong winds and heavy industrial dust circulation in the chimney consisted of visible damage to the chimney. For the determination of the current status of the chimney infrared detection devices were used for the location, identification of reinforcement steel bars. Tensile tests were used on reinforcing bars to determine the material properties of steel rebar. Compressive tests were performed on concrete core samples. After a detailed investigation a concrete jacketing method is utilized to strengthened the 59.2 m long chimney.

In this study, the free vibration analysis of the cross-ply laminated composite cylindrical shallow shells has been studied using shear deformation shallow shell theory (SDSST). First, the kinematic relations of strains and deformation are given. Then, using Hamilton’s principle, governing differential equations are developed for a general curved shell. Finally, the stress-strain relation for the laminated, cross-ply composite shells are obtained. By using some simplifications and assuming Fourier series as a displacement field, the governed differential equations are solved by the matrix algebra for shallow shells. Employing the computer algebra system called MATHEMATICA; a computer program has been prepared for the solution [1]. The results obtained by this solution are compared with the results obtained by (ANSYS) programs. In this article, regression method’s and SDSST method’s abilities in estimating the free vibration with the laminate number, aspect ratio, thickness ratio, curvature ratio and orthotropic ratio variables, are compared with different and similar aspects. In comparing with linear, interaction, quadratic and pure quadratic models, which are constructed with multiple linear regression approach, the quadratic model provides better results. http://ijaers.com/detail/investigation-of-multi-linear-regression-methods-on-estimation-of-free-vibration-analysis-of-laminated-composite-shallow-shells/ Ali Dogan, Omer Faruk Cansiz, Kevser Unsalan, Nurullah Karaca http://ijaers.com/uploads/issue_files/19 IJAERS-DEC-2017-24-Investigation of Multi Linear.pdf This paper presents the development of an instrumentation kit of voltage and current measurement for identification of the dynamic model and control of direct current (DC) motors.

The objective of this study is to conduct a literature review of environmental effects of surface water pollution. The method used for this study is a review of academic journal articles, internet materials, textbooks, bulletins, conference papers, project reports and publicly available materials on the environmental effects of surface water pollution. All previous authors whose works were reviewed agreed that anthropogenic activities greatly contributed to surface water pollution and spatial variation of physicochemical parameters over time and location more than other sources in terms of both chemical and physical water pollutants that indicated elevated values of major chemical parameters (lead, cadmium, chromium, copper and some anions) beyond the permissible/threshold limits set by regulatory bodies. They also had a unity of opinion that the parameters have adverse effects on human plants, aquatic and physical environment. From the review and based on the results of the previous studies, this study concludes that most surface waters across the globe are polluted and as such must be treated before use both for domestic and industrial purposes to avoid the spread of epidemics that can lead to deaths of humans who are the most precious of all creatures. Recommendations of the study include: (1) regular review of environmental effects of surface water pollution by researchers to indicate the trend in pollutional loads of rivers and streams across the globe; (2) strict enforcement of regulations water quality standards and (3) regular monitoring of the environments of water bodies by regulators and the locals. http://ijaers.com/detail/a-review-of-environmental-effects-of-surface-water-pollution/ Igwe P.U., Chukwudi C.C., Ifenatuorah F.C., Fagbeja I.F., Okeke C.A. http://ijaers.com/uploads/issue_files/21 IJAERS-DEC-2017-33-A Review of Environmental.pdf Soil erosion is a global environmental problem influenced by both natural and human factors. Modeling provides a quantitative and consistent approach to estimate soil erosion and sediment yield under a wide range of conditions, and is needed to guide the comprehensive control of soil erosion. Over the years various soil erosion models have been developed. The application of these models is dependent on the soil type and climate of the given area because models differ in complexity and input requirements. This paper reviews various soil erosion models and their applications, focusing more on the most widely applied models which are: Universal Soil Loss Equation (USLE), Revised Universal Soil Loss Equation (RUSLE) and Water Erosion Prediction Project (WEPP). The method used for this research is a review of academic articles, bulletins, conference papers, textbooks, research reports and publicly available materials on soil erosion models and their applications. The results of this study revealed that most soil erosion models have been developed for the assessment of rill and interill erosion at plot or catchment scale on agricultural lands and watersheds in terms of estimating mostly soil loss, sediment yield, erodibility (K) values, rainfall factor (R) factors, runoff rates and forecasts of likely impacts. Again, the study indicated that most previous authors on soil erosion assessment used the empirical models due to their limited data and parameter inputs. Recommendations of this study include: (1) expansion of the USLE and RUSLE models for the simulation of gully erosion and sediment processes; (2) researchers should be encouraged through grants to develop empirical models (that make use of limited data) based on rainfall (R) factor and erodibility (K) factor that provide two opposing forces in soil erosion processes; and (3) management of soil erosion based on the indigenous knowledge of the affected people and land holders. http://ijaers.com/detail/soil-erosion-a-review-of-models-and-applications/ Igwe P.U., Onuigbo A.A., Chinedu O.C., Ezeaku I.I., Muoneke M.M. http://ijaers.com/uploads/issue_files/22 IJAERS-DEC-2017-34-Soil Erosion A Review.pdf With the scarcity of fresh water, desalination is an important instrument to be considered for the production of non-salinized water through waste heat in the dual use of nuclear reactors.

Under physical properties, milling parameters (such as brown rice content, husk content and total milling recovery), hardness and dimensions (length, width & thickness) including water absorption capacity (by dipping at 70°C for four hours) were measured. Amylose content of each rice variety was determined by measuring the optical density of amylose-iodine complex using spectrophotometer, while amylopectin content was obtained using the relationship equation. Results revealed, brown rice content, husk content, total milling recovery, hardness and water absorption capacities of these rice varieties were within the range of 76-78%, 20-23%, 69-72% & 28-30% respectively. Statistical analysis also indicated, those physical properties of fourteen rice varieties were significantly different to each other (p0.05). http://ijaers.com/detail/identification-of-important-physical-properties-and-amylose-content-in-commercially-available-improved-and-traditional-rice-varieties-in-sri-lanka/ G.C.

Some properties of these new concepts are studied and the relation between them is revealed. http://ijaers.com/detail/on-fuzzy-length-spaces-and-fuzzy-geodesics/ Ugur Gozutok, Yasemin Sagiroglu http://ijaers.com/uploads/issue_files/29 IJAERS-DEC-2017-23-On Fuzzy Length Spaces.pdf Dam-break flows can cause major destructions in case settlements located atthe downstream area. Since many people live in the settlements, investigations regarding the dam-break flow have great importance.Dam break flow characteristics can become variousbased on different downstream conditions. In this study, an investigation was made relating tothe dam break flow in a channel with symmetrical triangular-shaped bottom obstacle using Finite Element Method (FEM) formulation. Numerical results of the present study were compared with experimental results. It was concluded that numerical and experimental results are in good agreement. http://ijaers.com/detail/numerical-investigation-of-dam-break-flowovera-bottom-obstacle-using-eulerian-finite-element-method/ Ada Yilmaz, Kaan Dal, Mustafa Demirci, Selahattin Kocaman http://ijaers.com/uploads/issue_files/30 IJAERS-DEC-2017-36-Numerical Investigation of.pdf In this study, a comparison was made between experimental and numerical analysis results using the classical dam-break test case over dry bed. DualSPHysics software based on Smoothed Particle Hydrodynamics (SPH) method was used to make the numerical analysis. Experimental data were obtained from Kocaman [1]’s laboratory setup through image processing technique. It was observed that the numerical and experimental results are in good agreement. http://ijaers.com/detail/validation-of-dam-break-problem-over-dry-bed-using-sph/ Kaan Dal, Stefania Evangelista, Ada Yilmaz, Selahattin Kocaman http://ijaers.com/uploads/issue_files/31 IJAERS-DEC-2017-38-Validation of Dam-Break.pdf As the name implies, the trichobezoar is a consolidation of hair, which, due to its structural properties, it is resistant to digestive enzymes and accumulates in the folds of the gastric mucosa, impacting with food remains and mucus. The starting frame is usually nonspecific and late, patients may remain asymptomatic for several years. Thus, the initial manifestations can range from symptoms common symptoms, such as epigastric discomfort, abdominal pain, nausea and vomiting, to severe cases of malnutrition and anemia due to ulceration of the gastric mucosa or abdomen acute, by intestinal occlusion or viscera perforation. The objective examination highlights in 80% of patients a palpable abdominal mass, typically epigastric, but without distinctive features on palpation, which makes it difficult to differentiate between a possible hepatomegaly or chorda colic, as initially seen in this patient. Halitosis or alopecia can coexist, which often go unnoticed, and require a more detailed anamnesis and subsequent investigation. Because of this presentation, the diagnosis can become difficult, as verified in the clinical case exposed, which eluded the initial clinical and imaging evaluation. http://ijaers.com/detail/cystic-intestinal-pneumatosis-in-the-context-of-gastric-trichobezoar/ Leandro Jaime Barreto Costa, Mário Gissoni de Carvalho, Ana Paula Nogueira Machado, Marcelo Fagundes Rocha http://ijaers.com/uploads/issue_files/32 IJAERS-DEC-2017-49-Cystic.pdf
