The study adopted a methodology widely disseminated in scientific research and income evaluations for the economic analysis. Through the economic indexes, we could evaluate the efficiency of the administrator and his workforce. Hierarchical clustering and Principal component analysis were used as multivariate analysis. The result of the economic analysis revealed that, on average, the total gross revenue from conventional management exceeded by 2.24 times the total gross income from agroecological management. However, the production costs of the conventional management exceeded by 2.15 times agroecological management. The multivariate analysis revealed that the variables are divided into three distinct groups formed between the equilibrium price and the profitability index, which do not correlate with each other or with the others, and by the subgroup formed by the return rate index, total operating profit and gross income, which are correlated with each other and not correlated with the others. We conclude that the multivariate analysis confirmed that the methodology used in the composition of all the economic indexes studied was correct. http://ijaers.com/detail/economic-and-multivariate-analysis-of-banana-production-musa-sp-cultivated-in-the-semi-arid-region-of-northeast-brazil/ José Aluisio de Araújo Paula, Eudes de Almeida Cardoso, Vander Mendonça, Roberto Pequeno de Sousa, Stefeson Bezerra de Menezes, Hugo Sarmento Gadelha, Patricio Borges Maracaja, Aline Carla de Medeiros http://ijaers.com/uploads/issue_files/3-IJAERS-JUN-2018-15-Economicandmultivariate.pdf Applying several economic indexes commonly used in national scientific research, we assessed the productive efficiency of banana crops in commercial areas of the Brazilian semi-arid region. The analysis of income, through economic indexes, provided an overview of the effectiveness of administration and workforce. The result of the multivariate analysis revealed (i) three independent groups composed by the total net profit, and (ii) a subgroup joined by the opportunity cost, the interest rate for the period from planting to harvest, and the leveling point. The best options for net return on banana propagation in the Brazilian semiarid region were (i) the use of conventional management, (ii) the cultivation of Pacovan cultivar propagated by rhizome without "ceva" and, (iii) use of the Dwarf Prata cultivar propagated by rhizome with "ceva". The economic resources applied to the banana production provided the best output among those evaluated since it exceeded four folds the obtained with the capital remuneration in the financial application. http://ijaers.com/detail/economic-indexes-of-banana-production-musa-sp-in-the-brazilian-semiarid-region/ José Aluisio de Araújo Paula, Eudes de Almeida Cardoso, Roberto Pequeno de Sousa, Stefeson Bezerra de Melo, Fabio Martins Queiroga, Hugo Sarmento Gadelha, Patricio Borges Maracaja, Aline Carla de Medeiros http://ijaers.com/uploads/issue_files/4-IJAERS-JUN-2018-17-Economicindexes.pdf The aim of this thesis work 'Design of electric vehicle including different power train components' is to design an energy model of electric vehicle including different power train components with the application of a design and  simulation tool, which in this thesis work would be MATLAB Simulink software. With this design and simulation, we expect to find the energy consumption by a vehicle by virtue of different types of forces acting on vehicle when subjected to different standard driving cycles.

Method: It has been used a construction method of Environmental Education Perception Index (IPEA) which has followed the logic of factorial analysis. Results: In general, the IPEA (Teachers) submitted a result considered "good". About the students, the result was troubling due to 75% of the of the schools studied submitted results considered only "regular". The average IPEA of formal public education at the fundamental level was considered "regular" at the IPEA of 0.597. Final Considerations:It does not notice an educational coherence for what is the strongest point in Guajará-Mirim: environmental preservation. It was possible to observe that the Guajaramirense society is experiencing a moment of institutional crisis, of values, ethics and behavior which reflects directly on the citizens’ attitudes that do not correspond to the status of a region with a strong environmental policy. http://ijaers.com/detail/environmental-education-perception-index-ipea-headed-for-sustainable-development-a-study-in-elementary-schools-in-the-city-of-guajar-mirim-rond-nia-brazil/ Carlos Alberto Paraguassu-Chaves, Fábio Robson Casara Cavalcante, Paulo Cesar Gastaldo Claro, Monica David Fischer, Paulo de Tarso Carvalho de Oliveira, Inarê Roberto Rodrigues Poeta e Silva, Zerisson de Oliveira Neto, Izan Fabrício Neves Calderaro, F http://ijaers.com/uploads/issue_files/6-IJAERS-JUN-2018-45-EnvironmentalEducation.pdf In recent years there has been great interest in studying parallel manipulators, mainly applied in flight simulators, with six degrees of freedom. The interest in parallel kinematic structures is motivated by its high stiffness and excellent positioning capability in relation to serial kinematic structures. This work presents the kinematic and dynamic modeling, design, development and identification of the parameters of motion platform with six degrees of freedom, electrically powered, for studies of flight simulators, is known as a Stewart Platform. It also presents the design of an H infinity controller with output feedback. The actuator model was obtained by a step voltage input to the engines and measuring its displacement by the encoders coupled, in each of the respective axes of the motors. Knowing the relation of motion transmission mechanism between the motor shaft and each actuator is obtained by the displacement rod from the rotation of motor which are measured by the corresponding encoder. The kinematics and dynamics platform’s data compose the whole systems models simulations that are applied in the Stewart platform to validate the model and show the effectiveness of control techniques in which was applied to control the position and orientation of the platform were performed. An inertial sensor Xsens MTi-G measurement of the Euler angles of the platform was performed. The result obtained by the controller was satisfactory and illustrate the performance and robustness of the proposed methodology. http://ijaers.com/detail/optimal-h-infinity-controller-applied-to-a-stewart-platform/ Ricardo Breganon, Marcio A.

Method: This is a descriptive, quantitative and transverse study. We used a structured instrument containing a series of variables, such as gender, age, histological types, more frequent neoplasms, lymphomas, leukemias, among others. We asked The Comitê de Ética em Pesquisa em Seres Humanos (Research Ethics Committee) to dispense the Informed Consent Form because the study did not require intervention on the patient or collection of biological material, and no possibility of constraints on patients and their relatives. Results: From 75 cases, 32 (42.7%) were female and 43 (57.3%) were male. Regarding the distribution of patients according to the age group, 21 (28.0%) were younger than 4 years, 12 (16.0%), 5 to 9 years, 17 (22.6%) from 10 to 14 and 25 (33.4%) from 15 to 19. The most frequent histological types by gender were leukemias of myeloproliferative diseases and myelodysplastic diseases with 30% and 50% new cases in the period, followed by lymphomas and reticuloendothelial neoplasms with 16.65% and 20, 0% of the histological types in the period. Leukemia in the hematopoietic and reticuloendothelial system (C42) is the most frequent cancer in both, female and male gender, with 47.5% of cancers in the biennium. The second group of cancers in children from 0 to 19 years old and location of the primary tumor is the encephalon carcinoma (C71), with 11.25% of the new cases. Conclusions: The results presented with their proper nuances are in agreement with the data of studies carried out in Brazil and in other countries. http://ijaers.com/detail/analysis-of-histological-frequency-and-pediatric-cancer-in-rond-nia-western-amazonia-brazil/ Carlos Alberto Paraguassú-Chaves, Rafael Ayres Romanholo, Laurindo Pereira de Souza, Rodrigo Rodrigues Aguiar, Fabrício Moraes de Almeida http://ijaers.com/uploads/issue_files/8-IJAERS-JUL-2018-5-Analysisofhistological.pdf Much effort is now being made to reduce the emissions of internal combustion engines (ICE) to comply with increasingly stringent environmental regulations. In parallel with this objective several studies are conducted with the objective of making ICE increasingly energy efficient, thus reducing the consumption of fossil fuels. This article proposes to present a new concept that can work together with others to reduce the emissions and improve the efficiency of small engines that operate in partial loads.

The use of motion platforms together with a virtual simulation is what is most recent in this field, due to its global approach to a flight. However, these flight simulators generate a great added value, so that for trivial trainings and entertainment their use becomes impracticable. With this in mind, in this work was presented a low cost project of a new model of flight simulator containing both simulations, visual and motion. More specifically, this work aims to demonstrate an analytical method for calculating the drives of the designed simulator, so that it supports the loads of the structure and user, in addition to the dynamic torque required by the simulation platform. Furthermore, it was shown how to obtain the inertia of a complex structure as designed using SolidWorks software and also how to acquire magnitudes such as acceleration and angular velocities using Flight Simulator X and Link2FS Multi software. Finally, with the torque and power values ​​required to perform the pitch and roll movements, a commercial selection of the motors was made for platform so that these drives would supply the demand of both torque and power. http://ijaers.com/detail/analytical-calculation-of-the-drives-of-a-flight-simulator-platform-with-2-degrees-of-freedom/ Weslei Patrick Teodósio Sousa, Túlio Pinheiro Duarte, Bruno Rodrigues Castro, Tarcísio Flávio Umbelino Rego, Pedro Américo Almeida Magalhães Júnior http://ijaers.com/uploads/issue_files/10-IJAERS-JUN-2018-20-AnalyticalCalculation.pdf Direct shear (DS) tests with controlled shear rates were performed in two soils from the Baixada Fluminense region, in the city of São João do Meriti – Rio de Janeiro, Brazil. The first soil characterized as Inorganic Clay of high plasticity (CH) was located in a hillside region. The second soil characterized as medium plasticity clay (CL) was located in a central region of the studied area with a slight slope. The soils in question are deposited on non-compacted soft soil with the addition of Municipal Solid Waste (MSW). Both samples of compacted soil were excavated at a depth of 1.0 m, and undisturbed samples were collected. In addition to the previously mentioned tests, oedometric tests and soil physical classification tests were carried out to evaluate geotechnical parameters. In both tests the shear rate of 0.043 mm / min was adopted. The tests presented coherent results with probabilistic accuracy greater than 95% inreliability compared to three tests with compacted tropical soils. http://ijaers.com/detail/determination-of-resistance-parameters-of-contaminated-compacted-tropical-soils-in-the-state-of-rio-de-janeiro/ Fernando B.

The fibres of oil palm EFB has been treated using seawater from Pulau Tiga, at day-3 until day-30, the different filler loading of 1%, 3% and 5% of untreated and treated composites were prepared using casting method. The thermal properties of the composites of untreated and seawater treated were analysed using Thermogravimetric Analysis (TGA). Based on the thermal effect, Pulau Tiga composites have the good thermal stability due to the highest onset temperature. The morphological examined using Scanning Electron Microscopy (SEM). The morphological changes enhanced with the seawater treatment, however, at the filler loading of 5%, the composites easily cracked with more voids detected. In conclusion, seawater treatment significantly improved an extra enhancement in thermal stability and the morphological changes improved with the seawater treatment at 1% of the fibre loading. http://ijaers.com/detail/the-effect-of-the-seawater-treatment-on-the-thermal-and-morphological-properties-of-oil-palm-empty-fruit-bunches-filled-poly-vinyl-alcohol/ Siti Ayu Aziz, Mohd Sani Sarjadi http://ijaers.com/uploads/issue_files/12-IJAERS-JUN-2018-48-The EffectOf.pdf This is a documental research, whose main objective is to present indicators for a new mapping of Local Productive Arrangements (APLs) in Rondonia and, specifically, discuss the dynamics of reference data and its importance to the investment policies with a view to regional development. he data were calculated from tables of the Annual List of Social Informations (RAIS, 2012), presented by the Regional Secretariat of the Ministry of Labor and Employment (MTE) (BRAZIL, 2014), and by census of vegetal extraction, agriculture and sylviculture available on the IBGE website, relative to 2013. It was observed that most of the APLs identified in previous studies have not been confirmed by the data of the RAIS and of the IBGE. From these data, we identified more than 100 potential APLs in the State, while are currently presented only 18. The cattle breeding, for example, appears in the previous studies restricted to a microregion only, but it is significant in seven of the eight microregions of the State. Are also quite significant the production data of fruit and fish, among other products, confirming a diversified economy in the agricultural sector; in the secondary sector, however, there are few references, most notably in larger businesses involving wood, civil construction, and strictly in Porto Velho, electricity. It is suggested to be made larger investments for APLs studies in the State, including for full mapping not only per Microregion, but also by the city, in order to identify best opportunities, fill the gaps, offer support and strengthen the endeavors. There is much that can be allocated as resource in the Multi-Annual Plans of State. http://ijaers.com/detail/regional-development-and-the-indicators-for-mapping-of-local-productive-arrangements-of-rond-nia-brazil/ Sergio Francisco Loss Franzin, Fabrício Moraes de Almeida http://ijaers.com/uploads/issue_files/13-IJAERS-MAY-2018-22-RegionalDevelopment.pdf The term experimental design is characterized by the manner in which the portions are distributed in a given experiment. The completely randomized design is the most commonly used among experimental designs because the principles of randomization and repetition provide authenticity of the conclusions due to guarantee that the experimental units (plots), even if distinct and exhibit equal probability of being distributed to the groups. It is widely used in experiments have uniform conditions as the experimental conditions are critical in obtaining a good experimental design. It offers a wide experimental application, but must pay attention to the test, that even homogeneous, can present experimental conditions that will harm the experiment. So in order to get a good design, an early collection of information to evaluate the homogeneity of the experimental conditions is critical.

This study proposes the use of this type of material to attenuate noise of medium frequencies (100 – 600 Hz), predominant in structure-borne noise, complementing the existing ones, in order to refine the vibroacoustic behavior of the vehicle. Sound absorption materials are easy to handle, have a lower cost and require a short time for implementation.For the development of this work, a car cabin prototype was built using tubes and steel plates for the experimental tests.A finite element numerical model was created to obtain the vibrational behavior of the panels in this frequency range through modal analysis test. Experimental tests were performed on vibroacoustic frequency response function (FRF). It was observed in the tests performed that the application of sound absorption material attenuates significantly the vibration noise of panels in the range of medium frequencies, from 100 to 600 Hz. This methodology will allow the development of proposals for noise attenuation solutions and refinement of acoustic comfort with lower time and costs. http://ijaers.com/detail/methodology-to-vibrational-noise-attenuation-of-panels-in-vehicles-through-sound-absorption-materials/ Rogério Gondim Costa, Tiago Simão Ferreira, Claysson Bruno Santos Vimieiro http://ijaers.com/uploads/issue_files/17-IJAERS-JUL-2018-6-MethodologytoVibrational.pdf The learning process at first only lasted one direction or just focused on teachers (teacher centered), such as the concept of behaviristic.

Cooperatives contain the meaning of "cooperation". From an economic point of view, "cooperation" can be "profit oriented" and can also be "non-profit oriented". Profit-oriented cooperation is cooperation in capital. This partnership grow up as business entities whose main purpose is to foster capital to gain maximum profit as applicable to the company. While non-profit oriented is the cooperation that forms a business entity that is not solely emphasized to profit but more strived to serve of its members. Because the cooperative is a business entity consisting of people, a cooperative or legal entity, with the basis of its activities based on the principle of cooperatives as well as the people's economic movement, which is based on the principle of kinship.

It has many uses in medicinal, culinary and ayurvedic purposes. Garlic peeling is a tedious, time consuming and laborious work. So far, traditional peeling methods are used for garlic peeling. These methods are observed to be unhygienic, laborious and caused high damage to garlic segments. Mechanical peelers available are costly and not affordable to small scale industries. Since, the traditional methods are laborious and mechanical methods are costly there is a need to develop low cost, mechanical peeler that will reduce the drudgery. Angular iron and flat iron was used for main frame and supporting the main units. A food grade rubber and mild steel pipe was used for rubber roller. Iron bar was used for shaft. A wire mesh was used as screen. Dimensions of garlic segments were measured using digital vernier callipers and weight of each garlic segment was measured using electronic balance. Moisture content, orthogonal dimensions, weight, geometric mean diameter, sphericity, equivalent mean diameter, shape factor, terminal velocity and drag coefficient of garlic segments were found. Moisture content of garlic segments was 59.36±0.87% (w.b). At this moisture content, average length, width and thickness of garlic segments were found to be 25.818 3.743 mm, 10.116 2.209 mm and 7.34 1.638 mm, respectively. Average weight of individual garlic segments were found to be 1.159 g. Geometric mean diameter, sphericity, equivalent mean diameter and shape factor of garlic segments were found out to be 12.422 mm, 0.481, 13.03 mm and 0.218, respectively.

Srujana http://ijaers.com/uploads/issue_files/24-IJAERS-JUL-2018-11-Designand.pdf In Brazil the fruit growing is becoming more and more technified, obtaining with this better quality and productivity. As fruit varieties are regionalized and harvested at different times of the year, they need post-harvest conservation techniques to be offered in different regions of the country during the off-season. For these reasons, management of the Cold Chain (CC) logistic process in post-harvest refrigeration and preservation of fruits is the way to overcome these problems. In this context, the research aimed to analyze how the TODIM Method of Multicriteria Decision Support contributes to the process of comparing forced air pre-cooling (24hs) and cold storage (30 Days and 60 Days, CAT1 - 80 and CAT1 - 198) in Normal Atmosphere (NA) and Controlled Atmosphere (CA) 24hs. The methodological procedures adopted were: exploratory and descriptive research, with qualitative approach and field research. In the field research carried out at the Cooperserra cooperative, the following results were identified: (1) feasibility of the implantation of the rapid precooling process to the hydrocooling by immersion proving to be efficient in the application of the system, in relation to the precooling for forced-air cooling in the chamber combined with storage; (2) the management of the Cold Chain (CC) logistic process in the pre-cooling and storage stages maintains the quality of the Fuji apple (Malus Communis). In addition to contributing to academic research, the study corroborated the development of best practices in the management of the Cold Chain (CC) logistics process and commercialization, providing elements for companies to plan the logistics processes incorporating the precooling and storage stages of the Fuji apple (Malus Communis). It was concluded that in the pre-cooling to the cold water, it does not need that the apple stays for 24 hours in the cold chamber to reach the appropriate temperature of 2º C, it was verified that in 25 minutes of cooling the fruit reaches the temperature of 5ºC , maintaining the quality of the fruit and optimizing the energy expenditure of the cold room. http://ijaers.com/detail/comparison-of-pre-cooling-and-storage-processes-for-fuji-apple-quality-maintenance-using-the-decision-support-method/ Joaquim Rodrigo de Oliveira, Cristina Keiko Yamaguchi, Stéfano Frizzo Stefenon, Reny Aldo Henne, Cassandro Albino Devenz, Matheus de Oliveira http://ijaers.com/uploads/issue_files/25-IJAERS-JUL-2018-23-ComparisonOf.pdf To solve the problem of the economic emission load dispatch (EELD) is necessary minimize the total cost of fuel consumption and carbon emission.

To evaluate this assumption,we asssed the potential use of nine wild types of pyocyanin-producing P. aeruginosain bioremediation. They exhibit concentrations of pyocyanin ranging from 0.08 to 28.68 μg/mL.Hydrocarbonoclastic activity in the presence of pyocyanin was determined by two protocols. First, ahigh correlation was found between the synthesis of pyocyanin and the emulsification index of lubricating oil. Second, two strains were tested for their ability to degrade anthracene and pyrene in soil by the concentration of pigment produced.Microcosms were filled with 250g of sterile sandy soil, supplemented with glycerin and then contaminated with a 20 mg/kg of mixture of the two compounds. The volume of the inoculum suspension (≈108 CFU/mL) was equivalent to 5% of the soil mass contained in the microcosms. Static incubation lasted 60 days at 25°C. A roughly 60-fold difference between the pigment concentrations produced by the two strains resulted in an increase of 65 and 45% in the pyrene and anthracene biodegradation, also indicating that the molecule served as a co-substrate of pyrene degradation. http://ijaers.com/detail/correlation-between-pyocyanin-production-and-hydrocarbonoclastic-activity-in-nine-strains-of-pseudomonas-aeruginosa/ Andrwey Augusto Galvão Viana, Bianca Teixeira Morais de Oliveira, Thiago Gonçalves Cavalcanti, Kally Alves de Sousa, Elisângela Afonso de Moura Mendonça, Ian Porto Gurgel do Amaral, Ulrich Vasconcelos http://ijaers.com/uploads/issue_files/28-IJAERS-JUL-2018-32-Correlationbetween.pdf The present work analyses the administration within a school organization from a pedagogical perspective, understanding that pedagogical coordination acts with the management, being responsible for coordinating the progress of the work in the organization, ensuring the articulation of interpersonal relations, the conditions for the personal and professional development of the people of the school. The research was carried out in one school maintained by Brazil’s federal government, located in the city of Rio de Janeiro that is attended exclusively by students in the initial years of fundamental education. As instruments of data collection, a structured interview and a semi-open questionnaire were used.

The aim of this research is to assess and compare the treatment performance of existing community based technologies which are affordable, manageable and climate compatible in Tanzania. The selected existing decentralized technologies for this study were Anaerobic Baffled Reactor (ABR) found in Kigamboni, Dar es Salaam and Constructed Wetland (CW) found in Mbagala, Dar es Salaam. Wastewater samples in and out of these systems were collected and analyzed for physical, chemical and biological parameters. The observed average effluent concentration of BOD5 (67.5, 90 mg/L), NH3-N (276.6, 115.7 mg/L), PO4-P (13.2, 17.7 mg/L) and FC (9 x106, 4.2x106 counts/100mL) in ABR and CW, respectively testified to an inferior standard of treatment caused by mismanaged operation and maintenance. Both ABR and CW with slight adjustment were found to be effective in removal of all physical, chemical and biological parameters. http://ijaers.com/detail/performance-analysis-of-anaerobic-baffled-reactor-and-constructed-wetland-for-community-based-wastewater-in-dar-es-salam-tanzania/ Anesi Satoki Mahenge, Michael Duncan Malabeja http://ijaers.com/uploads/issue_files/30-IJAERS-JUL-2018-27-PerformanceAnalysis.pdf In this work, an approach to implement a simplified fuzzy inference model for monitoring the conditions of workings of power generators through the pressure values ​​of combustion temperature and engine water pressure is displayed.

The objective is to analyze and compare the evacuation times of a fire drill and a computer simulation in an educational building. The method consisted of a fire drill with prior notice of a 4-floor building with classrooms in a public university. A computational model was developed for the same building and population using the evacuation simulation software Pathfinder. The results were that the evacuation times observed in the computer simulation were slightly lower than the times of the fire drill because people covered smaller distances due to the random distribution performed by the Pathfinder software and because in the drill some time was spent for the start of the movement toward the exit, which was estimated at around 30 seconds, while the software was configured for a pre-movement time equal to zero. The use of the computer simulation, therefore, proved to be an effective solution to replace the fire drill, since it allows for the identification of design failures and for the simulation of different scenarios in less time and without the need to mobilize people. http://ijaers.com/detail/computer-simulation-and-fire-drill-in-an-educational-building/ Fábio Corrêa Gasparetto, Sílvio Edmundo Pilz, Roberto Carlos Pavan, Marcelo Fabiano Costella http://ijaers.com/uploads/issue_files/32-IJAERS-JUL-2018-18-ComputerSimulation.pdf The objective of this study was to investigate the changes caused by a program of physically-based physical exercises in the arterial blood pressure (SBP) values of elderly, hypertensive and sedentary women undergoing pharmacological treatment. Two study groups were formed, totalizing 33 subjects with ages ranging from 60 to 75 years, which were constituted as follows: a) an experimental group (EG), composed of 18 hypertensive and sedentary students, under pharmacological treatment and attending the Center of Physical Activity of the Banco do Brasil Athletic Association of Itaberaí, Goiás, Brazil, which during the experiment were regularly submitted to physical exercise routines (Age: 63.8 ± 14.8, Body Weight: 74.7 ± 13.8, Height: 165.8 ± 12.6); and b) a control group (CG), composed of 15 students also hypertensive and sedentary, under pharmacological treatment, who during the study were not submitted to physical training routines (Age: 71.6 ± 15.1; Body Weight: 68, 3 ± 13.8, Height: 160.3 ± 12.8). The experimental procedure had a total duration of 10 weeks, in which the EG was submitted to aerobic physical exercises controlled by the perceived effort index, associated with resistance exercises aimed at localized muscular resistance, and the training sessions were performed on Mondays, Wednesdays and Fridays 60 minutes each. At the end of the procedures the statistical analysis allowed to observe that the PASS scores presented by the SG and GC accounted for p = 0.000 and p = 0.150, indicating statistical significance only for SG, whose mean values ​​were reduced by 6.5 mmHg, differently from the scores of CG, which decreased by only 0.5 mmHg, representing 5.16% and 0.36% of functional improvement in the variable in question. A similar behavior was found when analyzing the PASD values, which at the end of the experimental procedure had a p = 0.017 and p = 0.051 for the EG and CG, respectively. Likewise, statistical significance was detected only in the EG, whose mean scores decreased numerically by 4.0 mmHg, distinct from the CG that involved only 0.7 mmHg, meaning 4.60% and 0.82 %% of physiological improvement in the variable under discussion. These findings suggest that a physical exercise program built on a scientific basis may be a valuable tool in nonpharmacological therapy for arterial hypertension. http://ijaers.com/detail/effects-of-an-exercise-program-on-the-levels-of-arterial-blood-pressure-older-women-hypertension-and-sedentary-in-pharmacological-treatment-process/ Helio Franklin Rodrigues de Almeida, Leonardo Severo da Luz Neto, Fabrício Moraes de Almeida, Luiz Carlos Cavalcanti de Albuquerque, MarcuceAntonio Miranda dos Santos, Liliane Lellis, Eunice Ribeiro Beltrão http://ijaers.com/uploads/issue_files/33-IJAERS-JUL-2018-36-EffectsofanExercise.pdf Strawberry cultivation is appreciated in many countries because of the fruit's well-defined, attractive and nutritional sensorial characteristics. As such, it is of great commercial value. The flavor and nutritional properties of the fruit are characteristics that have been developed and gaining importance, both in breeding programs and in productive systems. In this sense, this work proposes the application of nanotechnology for the improvement of the physicochemical characteristics of strawberry crops, with the main objective of analyzing the influence on nutritional performance of different fruit treatment doses with zinc oxide nanoparticles. The physicochemical analyses of the strawberry pseudofruitswere carried out from November to June 2016. The experimental design was in randomized complete blocks, in a factorial scheme, with 7 replicates. The collected data were submitted to analysis of variance with the F-test and the differences between means were compared by the Tukey test (P≤0.05).The treatment process of the strawberry crop with zinc oxide nanoparticles was shown to be efficient for anthocyanin nutrients and soluble solids. The method for analyzing vitamin C, which consisted in freezing the raw material, was ineffective, probably because of the reduction of ascorbic acid levels by the freezing and crystallization of the sample. Climatic factors significantly influence the nutritional composition of anthocyanins and soluble solids. The application of nanoparticles at 100% of the recommended dose proved to be more effective than zinc oxide in its natural form in increasing the soluble solids values. http://ijaers.com/detail/physical-chemical-properties-of-strawberry-pseudofruits-submitted-to-applications-of-zinc-oxide-nanoparticles/ Carlesso L.C, Luz G.L D, Lajus C.R, Silva L.L, Fiori M, Rossoni C, Fernandes S.C, Riella H http://ijaers.com/uploads/issue_files/34-IJAERS-JUL-2018-19-Physical-Chemical.pdf Humbang Hasundutan Regency is one of the regencies in North Sumatera, has 10 (Ten) subdistricts, 153 villages 1 (one) Urban Village.
