Sustainable development and environmentally friendly energy systems Omer, Abdeen Mustafa Energy efficiency Environment Renewable energy Sustainable development Technologies People are relying upon oil for primary energy and this will continue for a few more decades. Other conventional sources may be more enduring but are not without serious disadvantages. The renewable energy resources are particularly suited for the provision of rural power supplies and a major advantage is that equipment such as flat plate solar driers, wind machines, etc., can be constructed using local resources. Without the advantage results from the feasibility of local maintenance and the general encouragement, such local manufacture gives to the buildup of a small-scale rural-based industry. This communication comprises a comprehensive review of energy sources, the environment, and sustainable development. It includes the renewable energy technologies, energy efficiency systems, energy conservation scenarios, energy savings in greenhouses environment and other mitigation measures necessary to reduce climate change. This study gives some examples of small-scale energy converters, nevertheless, it should be noted that small conventional, i.e., engines are currently the major source of power in rural areas and will continue to be so for a long time to come.

Deflection of laminated composite plates using dynamic relaxation method Suleiman, Osama Mohammed Elmardi Deflection program Deflection Dynamic relaxation method Laminated composite plates Orthotropic shear First – order orthotropic shear deformation equations for the nonlinearly elastic bending response of rectangular plates are introduced. Their solution using a computer program based on finite differences implementation of the Dynamic Relaxation (DR) method is outlined. The convergence and accuracy of the DR solutions for elastic large deflection response of isotropic, orthotropic, and laminated plates are established by comparison with various exact and approximate solutions. The present Dynamic Relaxation method (DR) coupled with finite differences method shows a fairly good agreement with other analytical and numerical methods used in the verification scheme. It was found that: The convergence and accuracy of the DR solution are dependent on several factors including boundary conditions, mesh size, and type, fictitious densities, damping coefficients, time increment and applied load. Also, the DR large deflection program using uniform finite differences meshes can be employed in the analysis of different thicknesses for isotropic, orthotropic, or laminated plates under uniform loads. All the comparison results for simply supported (SS4) edge conditions showed that deflection is almost dependent on the direction of the applied load or the arrangement of the layers.

A correlational analysis of academic stress in adolescents in respect of socio-economic status Jain, Paras Billaiya, Roshni Malaiya, Soman Academic performance Academic stress Adolescents Correlational analysis Respect of socio- economic status For students, the adolescent is a major transition in their lives since they make various decisions regarding all aspects of their lives such as academics, social life, and leisure activities. They have to struggle to meet the expectations of their parents which include desires related to their academic performance. In addition, society believes that studies with a high-rank from the reputed institute are a “passport” to a good job, high salaries, and high social status which is expected from students. As a result, the students are indirectly subjected to a variety of stressors mainly linked to academic success.

Aquifers selection to aid geoelectrical methods on drilled well building near the beach Simpen, I Nengah Redana, I Wayan Pujianiki, Ni Nyoman Umratul, Ika Aquifer Drill well Geoelectric method Near beach Sea water The aquifer was a rock form wherein the water was collected and as well as able to release water economically. The aquifers near the beach were susceptible to intruded sea water, especially areas that have a lot of groundwater taking, therefore, if building a well, should be chosen aquifer that had not been intruded sea water. It was needed a way thus, the water taken is not salt water or brackish water. This study has a long-term goal of finding a way to choose aquifer by geoelectric method aid. In order to build a drilled well, for getting the right aquifer. The research had been conducted in Candidasa Karangasem Bali with the geoelectric method. The results showed that there were two aquifers types, i.e. free aquifer with resistivity was 33.9 ohm.m and distressed aquifer with a resistivity was 70 ohm.m. Taking into account the two resistivity magnitudes, then, the free aquifer was thought to have been intruded by the sea water, while the distressed aquifer was thought to have not been intruded by sea water.

Use of concrete debris: Sub-base material for road structures Calderero, Ramona Panchana De Panchana, María José Calderero Lectong, Danny Moreira Hernández, Eduardo Humberto Ortiz Construction Earthquake Recycle Roads Sustainable Natural disasters in a very short time are capable of destroying what man has built using different types of resources, the construction of buildings, houses, etc. In their construction processes, they use different materials in a separate way that mixes and this process give them hardness and resistance to these materials. When they are destroyed they lose their individual properties and become waste; this research aims to make a study of the NEVI-12-MTOP standards, to be able to reuse the debris materials generated by the destruction of the earthquake on April 16. A bibliographic search was carried out related to the use given to waste caused by earthquakes in different countries. In the city of Portoviejo, the largest amount of debris was a concrete waste, and it can be concluded that these materials can be used as sub-base material in the road structures, so the reuse method was proposed. In particular, the characteristics of the residual materials were obtained as a result of the analysis of environmental, economic and material safety feasibility.

Aquifers selection based on geoelectric method data in the framework of drilling wells: A case study on international hospital project in Nyitdah Tabanan Bali Simpen, I Nengah Redana, I Wayan Umratul, Ika Aquifers Constructing drilling Drill well Geoelectricity method Unconfined aquifer The selection of aquifers based on Geoelectric Method data in constructing drilling wells was discussed in the present study. The research was conducted at the International Hospital Project in Nyitdah Tabanan Bali. The research position was around 8,5736 LS 115,1215 LE. Before the study was conducted, a well drill (well 1) has been made. The results showed that there were two types of aquifers, namely unconfined aquifers and unconfined aquifers. Related to this study, well 1 took water in the unconfined aquifers of 4 m depth. If the water kept taken for a long period, the quality and quantity of the water would be worse since well 1 was unconfined aquifers that took surface water. This would adversely affect the hospital building being built. The land around the building would be hollow due to the water loss, and the building would become unstable. Another drill well (well 2), based on geoelectricity data, can be made on 5,25 m - 18,75 m. In-depth 23 m, it was suspected that unconfined aquifers would have been found in well 2. After being drilled, aquifers were found in 23 m depth. Drilling was kept doing to 55 m depth.

The concentration of radon gas in air-conditioned indoor: Air quality can increase the potential of lung cancer Ratnawati, I Gusti Agung Ayu Sutapa, Gusti Ngurah Ratini, Ni Nyoman Air quality Air-conditioned room Gypsum Lung cancer Radon gas radiation Research has been conducted on the concentration of radon gas in air quality in air-conditioned rooms that can increase the potential for lung cancer. Indoor air quality is influenced by factors such as room occupants, material buildings, equipment and furniture in the room, contamination of pollutants from the outdoor air, seasonal influences, lighting, temperature, humidity, indoor noise, and ventilation. In addition, indoor air quality can be affected by radon gas. The concentration of radon gas is relatively high compared to other natural radionuclides. It is estimated that around 55% of the radionuclide concentration in nature comes from radon gas and is the largest source of radiation received by the world population, which is around 1.3 mSv/year. Based on the Risert of the National Institute of Occupational Health and Safety (NIOSH), America in 1997 as many as 52% of respiratory diseases associated with sick building syndrome stemmed from a lack of ventilation in the room and poor AC room performance, thus increasing the potential for lung cancer. The method used in this study is to determine the physical quantity and concentration of the radiation dose of radon gas in the room. The results show that air quality in terms of temperature, humidity, and noise is significantly still in compliance with environmental health requirements according to Kepmenkes No. 1405/Menkes/SK/XI/2002. But the lighting in the room has not been significantly fulfilled. Rooms with gypsum ceilings increase radiation doses and air-conditioned rooms can accumulate radiation doses evenly in the room.

Challenges and technical requirements for integration of renewable energy sources in Cuban electric system Fernandez, Miguel Castro Lanes, Miriam Vilaragut Rozas, Miriam Lourdes Filgueiras Sains de Fuentefria, Ariel Santos Gamez, Maria Rodriguez Distributed generation Microgrids Renewable energy sources Sustainable development Weather conditions The decision of the Cuban Government to massively introduce Renewable Energy Sources (RES) as a way to change the energy matrix, and in particular, the electricity matrix, is presented as an opportunity to introduce not only sources of energy friendly with the environment, but also make the contributions that, without limiting the development of the country, respond to the UN Millennium Development Goals (UNMDG). However, the large-scale use of RESs in an electrical system such as Cuba, isolated and not interconnected to other systems, can have a group of challenges that must be taken into consideration when it is exploited, since it does not incorporate only new technologies, some of which depend on weather conditions such as solar, wind and hydro technology for the production of electricity, but allow us to think about the introduction of emerging technologies that can increase the penetration of RES in the electrical system and introduce new management concepts, both territorially and nationally. The present work reflects on this, from some experiences that have been analyzed in different research works carried out at CIPEL, plus other international experiences.

Transposition of medium and long transmission lines Jurado, Washington Colon Castillo Fernandez, Miguel Castro Arauz, Wilber Manuel Saltos Chilan, Julio Cesar Hernandez line transposition matlab Sim Power Systems structure geometry transmission lines The transmission lines must be balanced electric circuits, theoretically, it must be an equivalent circuit that takes into account the uniform distribution of the parameters along the line. When it comes to transporting energy over long distances it is necessary to consider the effect of the capacitance, since each phase has a different capacitance causing each line to introduce an imbalance to the electrical system, for this reason, it is necessary to study the transposition of the cables. In the present work, several simulations of transmission lines with and without transposition are made, and the voltage unbalance that occurs as the line is longer has been verified. The simulations have been carried out under conditions of balanced load and fixed voltage in the arrival bar. Using the Sim Power Systems tool from Matlab, it was possible to check the behavior of the parameters of the line, depending on the geometric layout of the structure and its length. By applying this software, the objective is achieved by checking the stress unbalance problems suffered by a transmission line when transposition is not made.

Harmonics influence on power and energy measurements Trujillo, Armando E. Garcia energy control harmonics MATLAB simulation measurement nonlinear loads To carry out the control and trade of electric energy, power and energy meters are used profusely. This article discusses the differences in the power and energy readings of the measuring instruments of different types and their use for the control of the quality of the supply and consumption of electrical energy. The contradictions of these readings are analyzed when measured in consumers of non-linear loads, generators of harmonics, and of linear loads, consumers of them. Simulation methods are used to show how harmonic propagation occurs in the system. MATLAB Simulink is used as a method of simulation with generating harmonics loads and linear loads. It analyzes how the parameters of the energy quality of the consumers can be affected and it is proposed to use the measurement of the active power of the harmonics as a means of control and penalization.

The method used is a solid state reaction. The phase formation of the sample Ba1-xLaxFe12O19 was carried out at 1200oC for 2 hours. The results of the X-ray diffraction pattern analysis show that all sample compositions have a single phase BaFe12O19. The results of magnetic properties testing using VSM showed that the best coercivity field and remanent magnetization values were obtained at the composition of x = 0.04. The effect of substitution of lanthanum into the barium atom can increase the number of magnetic domains which are indicated by the increase in the coercivity value of the material along with the increasing composition of x. It was concluded that the composition of Ba1-xLaxFe12O19 is a permanent magnet with the best product energy.

Technical-economic impact of low voltage secondary lines to pre-assembled Giler, Steven Ruben Briones Loor, Carlos Javier Sailema Moreira, Jean Carlos Maciás Zambrano, Bryan Alexander Muñoz energy low voltage materials pre-assembled technical-economic Distributed generation is understood as all those sources of electrical energy that are connected in the electricity distribution networks. These distribution networks have been planned with wide operating margins, which together with the characteristic that energy flows are unidirectional (from the substation to consumers) allow them to be operated passively. This means that they are not subject to constant monitoring of the network status variables (ie voltages, flows), so these networks are managed with little supervision since that is more economical. The objective of this research is to investigate the economic impact that is presented within the university for a better presetting in the low voltage lines for them, the causes and effects that can be committed when installing them have been investigated, in addition to making a bibliographic review of how in other countries and within our city Portoviejo is distributed in low voltage and its consequences or benefits.

The linearity of x-ray devices radiation output and its relationship with patient thickness Ratnawati, I Gusti Agung Ayu Suandayani, Ni Komang Tri Sutapa, Gusti Ngurah devices radiation output linearity patient thickness quality control-QC X-ray Utilization of X-rays in the medical field is one way to improve public health. X-rays are one of the applications of radiation for radio diagnostics. X-ray examination using X-rays can provide information about the human body without the need for surgery. In the use of radiation technology it is realized that in addition to its use for radio diagnostics, X-rays harm the environment and living things around them, especially radiation workers. The impact that can result in cancer due to the accumulation of radiation dose exposure received by the body exceeds the specified threshold dose. Therefore safety standard guidelines that contain basic requirements for quality control (Quality Control -QC) must be obeyed. One of the test activities included in the QC program is the linearity test of X-ray radiation output.

Analysis of working conditions to which the triaduct is subjected in Roca Fuerte route - Manta Mendoza, Ana Valeria Palacios Viteri, Carlos Gustavo Villacreses Menendez, Edgar Antonio Menendez bridge sewer triaduct working conditions hydraulic flow In the work, the working conditions to which the triaduct is located in the Rocafuerte - Manta road are analyzed, with vehicle service conditions similar to those of a bridge since they share the same scenario. Despite their similarities, these two civil works, bridges and sewers, have a different structural behavior and design; The bridge sits on supports that are placed from end to end or in an intermediate way, while the sewer has a base that covers the entire area on which it will settle under a concept similar to that of a shoe or foundation slab, it also has with walls on its sides fulfilling the function of walls, which gives a drawer shape to this structure and hence its name. The working conditions of the aforementioned triaduct are analyzed, which are caused by vehicular traffic, earth thrusts, hydraulic flow, seismic load and a filler load that could be placed on the upper road slab that is not present on a bridge and corresponds to a dead load distributed because of the filling.

Impact of distributed generation in the electrical system of Ecuador Sumba, Edison Fabián Sumba Sumba, Angel Victor Sumba Castillo, Guillermo Antonio Loor Rodríguez, Jesus Alberto Pérez benefits distributed generation electric systems power renewable energy Decentralized generation today assumes a very important role in the stability of electric power, especially in rural areas where electric power supplied by large Power plants, is delivered to points of consumption with a poor quality of energy this due to the distance that is found, from the generation to the final consumer, the implementation of the GD is directly related to the increase in the quality of electric energy as well as providing flexibility to the electrical distribution system. The deployment of distributed generation in electricity distribution networks can potentially increase their reliability and reduce the cost of power, by installing energy sources closer to the demand or consumption points. This type of generation involves a great variety of energy sources, such as; wind, solar, hydraulic, fossil fuels, biomass, among others.

Obtaining biogas product from biological residues vaccines in Chone city Mantuano, Janner Leonel Santos Macías, Manuel Enrique Vergara Toapanta, Erik Sebastian Sanchez Palma, Klever Steven Tubay Giraldo, María Fernanda Vivas anaerobic fermentation biodigester biogas biological wastes renewable energy In this research, we studied the use of cattle biological waste to obtain biogas through a biodigester in the city of Chone, considered the livestock capital of Ecuador. Biogas is a mixed gas produced by the fermentation (anaerobic digestion) of organic materials in the absence of oxygen. It is mostly composed of methane and carbon dioxide. The biogas production process takes place in a container called a digester, in which the anaerobic fermentation process occurs. Obtaining biogas is one of the most used alternative sources for the production of renewable energy, so it can be evidenced by its importance as a tool against the fight of the environmental problem that exists today. The use of biogas of bovine origin has a high calorific value so it can be used for the production of heat, electricity or biofuel. This initiative seeks to manage and sustainably reduce organic waste, reduce the amount of greenhouse gas emitted into the atmosphere and reduce dependence on fossil fuels.

Rare earth ion contribution in barium hexaferrite structure to a change of magnetocrystalline anisotropy to improving its magnetic properties Adnyana, I Gusti Agung Putra Sukarasa, I Ketut Adi, Wisnu Ari barium hexaferrite coercivity magnetic rare earth structure Rare earth ion contribution in barium hexaferrite structure to a change of magneto-crystalline anisotropy to improving its magnetic properties has been investigated. A series of simples of Ba1-xCexFe12O19 with the variation of x (x = 0.0-0.5) were prepared by solid-state reactions using mechanical deformation techniques. The oxide materials used for sample preparation are BaCO3, Fe2O3, and CeO2 with the ratio of material used is adjusted to the stoichiometric calculation for variations of Ce4+ substitution. The phase identification results show that the reaction took place perfectly and successfully formed a single-phase Ba1-xCexFe12O19 namely at the composition x = 0 and x = 0.1.  while for the composition x> 0.1, it is formed in three phases. Particle morphology in the composition x = 0 and x = 0.1 has very good and uniform particle homogeneity across the surface of the sample in the form of polygonal particles. So the substitution of Ce atoms into the barium hexaferrite structure is only able at the composition limit x = 0.1. In the composition x = 0.1 has been able to increase the coercivity and magnetization fields. It can be concluded that the permanent magnet with the composition Ba0,9Ce0.1F12O19 gives the best results.

Potential risk of cancer in body organs as result of torak CT-scan exposure Suryatika, Ida Bagus Made Anggarani, Ni Kadek Nova Poniman, S. Sutapa, Gusti Ngurah body organs breast cancer risk CT-scan lung A concise and factual abstract Computed Tomography (CT)-Scan is a radiological diagnostic tool using a computer to reconstruct data from the absorption of a particular tissue or organ that has been penetrated by X-rays to form an image (imaging). The use of scanning equipment (scan) that emits radiation has the potential to cause quite serious impacts. According to researchers from Canada, Britain, and the United States published in The Lancet Medical Journal (2012), it is stated that children who are exposed to CT-Scans can be up to three times more likely to develop blood, brain, or bone cancer later in life. It further states a potential cancer risk exists due to the ionizing radiation used in CT-Scans, especially in children who are more sensitive to radiation than adults. A chest CT-Scan is one of the most frequently performed parts of the examination because this section contains many vital organs. The analysis showed that the effective dose of the liver was 0.241 mGy, breast, and lung was 0.724 mGy. The risk of cancer in each of the liver, breast, and lung organs reaches 0.038%, 1.160%, and 1,200%.

Spectral reflectance and principal component analysis on the distribution of clove vegetation using Landsat 8 Yuliara, I Made Ratini, Ni Nyoman Windarjoto, Windarjoto Suandayani, Ni Komang Tri clove distribution Landsat 8 normalized difference vegetation index (NDVI) principal component analysis (PCA) spectral reflectance This paper discusses the distribution of clove vegetation in Buleleng Regency, Bali using a vegetation index extracted from Landsat 8 imagery based on spectral reflectance and Principal Component Analysis (PCA). Data analysis used the Normalized Difference Vegetation Index (NDVI) transformation and PCA band transformation. Adjustment of the position of clove vegetation in the image is determined by the measurement results of the clove coordinate sample in the field. The results showed that the accuracy of the area of ?? clove vegetation distribution as measured as a percentage comparison to the area data of the Forestry and Plantation Service, Buleleng Regency, Bali in 2014, was 97.066% for the spectral reflectance-based vegetation index (NDVIref) and 97.072% for those based on PCA ( NDVIpca). The distribution class category with the dominant area identified into heavy class (NDVIref) of 7841.25 ha and moderate class (NDVIpca) of 7591.77 ha. There is a difference in the two determinant coefficient values ?? (R2), which is 0.2407% and at 5% significance, the variants of the B4 and B5 spectral reflectance image variable data variants, as well as the C1 and C2 component image variables simultaneously, can affect the NDVI vegetation index.

Telecommunications and virtualization in times of pandemic: impact on the electrical engineering career Intriago, Carlos Zambrano Posligua, Tony Ivan Quijije electrical engineering higher education pandemic TIC virtualization With the surprise arrival of Covid-19 at the end of 2019, the course of the world has undergone a 360° change, directly hitting the commercial, business, tourism, and especially the sector educational. This “pandemic” has forced the transfer of classrooms to the homes of students and teachers, bringing with it problems and at the same time solutions to the different aspects and points of their lives outside the student and work environment. Some of these problems lie in personal and family relationships. During all the chaos of the pandemic, Higher Education Institutions have had to adapt to what is known as “virtualization”, leaving aside tasks and face-to-face tasks completely. Thus, a mapping of the strengths and weaknesses of the University sector has been achieved, allowing these strengths to be enhanced to reduce weaknesses and be prepared for the next health emergency. This article tries to highlight the different difficulties that have appeared throughout the migration process from face-to-face to virtual. For this, it has been chosen to carry out surveys to certain students of the electrical engineering career, taking into account their point of view to establish a precedent within the investigation.

Temporal analysis on spectral reflectance of clove vegetation based on landsat 8 imagery Yuliara, I Made Ratini, Ni Nyoman Kasmawan, I Gde Antha clove vegetation Buleleng Regency Landsat 8 spectral reflectance temporal analysis This study aims to analyze temporally the spectral reflectance of clove vegetation using Landsat 8 multitemporal imagery data in Buleleng district, Bali. The analysis method uses the conversion of raw data from Landsat 8 images to the spectral reflectance value at the Top of Atmosphere (TOA). This conversion scales back the pixel values ??of the Landsat 8 image in the visible spectrum, namely bands 2, 3, 4 and infrared bands 5, 6, and 7 into percentage units. The temporal analysis technique is carried out by grouping the time series of Landsat 8 image data for 1 period, in 2015, into 4 quarterly groups based on the acquisition time, namely Quarter I (January, February, March), Quarter II (April, May, June), Quarter III (July, August, September) and Quarter IV (October, November, December). The results showed that the graph pattern of the average percentage of spectral reflectance in each quarter was the same and in the infrared spectrum was greater than the visible spectrum. The average value of the largest spectral reflectance was found in the second Quarter which was acquired by band 5 of 28.143%, while the smallest in the first Quarter which was acquired by band 2 was 2.503%.

Numerical study of frictional drag reduction using micro-bubbles in a vertical Couette-Taylor system Javadpour, Seyed Morteza Maryami, Reza Kadivar, Erfan Couette-Taylor system discrete-phase model drag reduction friction drag micro-bubbles In this work, we numerically study the reduction of frictional drag in a vertical Couette-Taylor system by using micro-bubbles. The silicon flow is in the annular gap between two concentric cylinders as the internal cylinder is rotating while the outer cylinder is stationary. Taylor vortices are formed between the cylinders and the rotational Reynolds number also varies from 700 to 4500. The carrier flow is silicone while air bubbles are constantly injected into the carrier phase at the bottom of cylinders and rise through the flow. By employing a discrete phase model and Euler-Lagrange approach, we investigate a two-phase turbulent flow. In this way, we study the distribution of the bubbles through the flow, which is acquired using numerical modeling. Our numerical results are in good agreement with the experimentally reported data for different values of Reynolds numbers. We also investigate the effect of injected air with a constant flow rate on the skin friction drag and on the drag coefficient ratio. Our numerical results illustrate a reduction of drag about 36% when microbubbles are injected into the system. This reduction can be achieved by the effect of the bubbles on the density of the fluid and transformed momentum.

Technical-economic analysis of the implementation of a microgrid with integration of renewable energies in the Esmeraldas Canton, Ecuador Chere-Quiñónez, Byron Fernando Martínez-Peralta, Alejandro Javier Mercado-Bautista, Jorge Daniel distributed generation renewable energies implementation microgrid technical-economic The integration of renewable energy technologies and the consequent reduction in investment costs has led to an increase in the use of distributed energy resources (DER), which has allowed the deployment of more and more microgrids. Despite the many benefits that can be derived from microgrids, they still face many barriers to participating in the electricity industry compared to traditional grids. This paper proposes to address the implications of installing renewable energy in the parish 5 de Agosto, Stone Mine Sector of the city of Esmeraldas, through a technical-economic analysis of the implementation of a microgrid using the HOMER network software. The analysis shows that implementing a microgrid for renewable energy production significantly reduces total costs, unit energy costs and carbon dioxide emissions over the entire project life cycle. Finally, it is concluded that the photovoltaic matrix produces 82.3%, wind turbines 15.3% and the contribution from the grid is 2.45% of the total energy, respectively.  The percentage of renewable energies in the system is 100%.
