http://ijaers.com/ Open Access international Journal to publish research paper en-us May 2018 The necessity of production involving the applicability of mathematics in the management decision-making process stimulates the elaboration of this article. This approach seeks to develop under a new profile of Mathematical Science, now as another tool of technological management, while it allows to understand the diverse deductive paradigms of this knowledge of support to the administrative process. In this way, the general objective is to deal with the application of mathematics as a tool in technological management; (1), to evaluate the applicability of these tools in the management of small and medium enterprises (2), to propose a mathematical model that contributes to the innovation of the business enterprise (3). The theoretical foundation is in the Taxonomy of Bloom, prescribed for the development of abilities and cognitive attitudes of the individual. There will be no doubt that mathematical problem-solving procedures advance significantly, especially to the demands of complex solutions. The Content Analysis Method and related procedures apply to this task. As a result .... Therefore, the study of mathematical and statistical application, in addition to computer resources to identify the possible trend in the index of technological management, the present article states that mathematics as a tool has its widespread applicability within the most diverse types of technological management, regardless of their size and showing how mathematics is associated in different areas of knowledge as a trend for technological management, since it is still considered for some as a difficult element among managers. http://ijaers.com/detail/mathematics-as-a-supporting-tool-for-technological-management/ Gilson Francisco Contreiras Diogo, Flávio de São Pedro Filho, Sued Santos Rocha de Souza, Gelson Barros Cardoso, Judes Gonçalves dos Santos http://ijaers.com/uploads/issue_files/1-IJAERS-APR-2018-49-Mathematics.pdf Use of nanomaterials in cementitious nanocomposites is a possibility to improving mechanical properties as well as increased durability. In this research the insertion of multi-walled carbon nanotubes (MWCNT) and particles of Calcium Silicate Hydrate (C-S-H) with Ca/Si=0.8 and Ca/Si=1.2 ratios were used in microconcrete specimens. The effects on the compressive and tensile strength were tested, besides analysis of the porous structure by mercury intrusion, as well as the microstructure by scanning electron microscopy. Nanocomposites were produced by varying NTCPM insertions at 0.1% and 0.2% and C-S-H inserts at 1% and 2%, all of them based on cement mass. The results showed that the nanocomposites with C-S-H insertion with Ca/Si=0.8 ratio were the least porous and presented the highest tensile and compressive strengths, reaching strength increases in the order of 30% compared to the control material because C-S-H insertion with Ca/Si=0.8 ratio is reactive and causes reduction of the total porosity. http://ijaers.com/detail/carbonic-nanoparticles-and-c-s-h-insertion-into-cementitious-nanocomposite/ Marcelo Adriano Duart, Oscar Endrigo Dorneles Rodrigues, Sérgio Roberto Mortari http://ijaers.com/uploads/issue_files/2-IJAERS-APR-2018-26-Carbonic.pdf This study investigated the implications of documentation of nursing interventions in the clinical settings. Documented nursing actions for 264 clients in the medical, surgical and maternity units of six health care facilities were obtained for the study using purposive and simple random sampling techniques. One research question and four null hypotheses guided the study. Checklist on nursing documentations in the clinical setting was used for data collection. Descriptive statistics of frequency, means and standard deviation (SD) were used to summarize the variables. Pearson Product moment correlation was used to answer the research question, while analyses of variance (ANOVA) was used to test the null hypotheses at 0.05 level of significance. The result showed that the core principles of nursing documentation significantly apply to all nursing documentations. In addition, significant differences existed across the units of the health care institutions with regard to the legal implications and the impacts of nursing documentation on quality assurance and science of nursing. http://ijaers.com/detail/nursing-interventions-in-the-clinical-settings-and-implications-of-the-documentations/ Edith N.

Currently one of the main problems faced is the occurrence of diseases, responsible for a worldwide economic loss, equivalent to US $ 9 billion per year. Aiming to increase resistance to diseases, increasing growth rates and food efficiency in intensive crops, some strategies have been developed, one of them is the use of probiotic bacteria. These, when in contact with the digestive tract of the host generates a series of benefits, among them, the modulation of the immune system, developing defense mechanisms and increasing resistance to stress. However, there are few documented reports on the efficiency of probiotics in native species, such as tambaqui (Colossoma macropomum). This species shows some resistance to stress, through physiological mechanisms of adaptation, such as lip expansion when subjected to hypoxia situations, which added to the positive effects of using probiotics would represent an increase in its resistance. The purpose of this work is to review the literature on the use of probiotics in aquaculture in order to provide a comprehensive synthesis of the current knowledge about its use in aquaculture, with emphasis on the intensive cultivation of tambaqui. http://ijaers.com/detail/probiotics-in-aquaculture-review-current-status-and-application-in-tambaqui-cultivation-colossoma-macropomum/ Valéria Maria de Melo Lima, Aloisio Freitas Chagas Júnior, Gessiel Newton Scheidt, Emerson Carlos Soares e Silva, Augustus Caeser Franke Portella http://ijaers.com/uploads/issue_files/4-IJAERS-APR-2018-43-Probiotics.pdf In Altas literaturas (High Literatures), Leyla Perrone Moisés reminds us that in the scope of Catholicism the canon acquired the meaning of a "list of saints recognized by the papal authority" which "by extension came to mean the set of literary authors recognized as masters of tradition" (1988, p. 61) .That, undoubtedly, guided the literary studies in Brazil until very recently. These studies ignored non-canonical literary works. In other words, the canonical thinking was oblivious to a rich literary production which was not in accordance with a colonialist view of the academic studies developed in our universities. In this work, we intend to study the literary production of some poets in Recife (Brazil), in the 1980s in relation to the established canon. We focus on the Movement, known as “Independent Writers of Pernambuco” aiming to bring to light a literary movement forgotten by Brazilian academic community.. Our study has a postcolonial perspectives we explore the need to pay attention to literary production by writers who do not always belong to “traditional canon” (Said, 2004). The poetical works of the movement we study may play a vital role in the context of Brazil and Pernambuco. By considering the emerging social responsibilities of writers and intellectuals in an ever more interdependent world, we suggest that studying the movement and its authors who are not much explored by Brazilian scholars we may be decolonizing the knowledge on literature in Brazil. Wetake into account the movement´s relations with Brazilian Northeastern culture and its program of action, dating from 1981, the beginning of the so-called "Lost Decade." The movement had an important voice against the most conservative and traditionalist criticism at that time. We believe that by studying the movement we are offering the opportunity to rethink our Brazilian and Pernambucan literary canon. http://ijaers.com/detail/space-city-and-post-colonialism-in-the-poetic-discourse-of-the-independent-writers-of-pernambuco/ Maria Elizabete Sanches, Miguel Nenevé, José Eduardo Martins de Barros Melo http://ijaers.com/uploads/issue_files/5 IJAERS-APR-2018-44-Space.pdf The Mishrif Formation represents an important succession in the southern Iraq and has extensive distribution in the Middle East. The present study is focused upon the stratigraphic sequence and basin development of Mishrif Formation in three important oil fields in the Mesopotamian Zone of Iraq are:- Halfaya oil field (Hf-1, Hf-272, Hf-316), Noor oil field (No-1) and Buzurgan oil field (Bu-2, Bu-3, Bu-4).There are several types of microfacies were recognized in the succession of the Mishrif Formation. Their characteristic grain types and depositional texture enabled the recognition of six facies associations (depositional environments) were distinguished in this Formation, they are: Basinal, Slope, Shoal, Biostorm, Back Shoal (restricted) and Lagoon associations facies.The microfacies analysis and reconstructed the paleoenvironments of the Cenomanian-Early Turonian basin in the studied area; there are three stages of the deposition: -First stage:- during this stage the basin of Rumaila Formation was continued to deposition the lower part of Mishrif within the basinal environment. The end of this basin (Rumaila basin) marked by appeared the open marine associated facies to the northwest basin which represent the mfs surface. The Highstand system distinguished by sequential the open sea facies to the shoal facies and biostorm. The first stage was finished by widespread of shoal facies in all studied area to marked a sequence boundary type II (prograde stage A).Second stage:- is represented by the developed the basin from the shoal to biostorm dominated facies with slow sea level rise. The presence of the open marine associated facies within the biostorm-shoal sequence marked the mfs surface. The final step of this stage was shown the shallowing up-ward by appeared the lagoon/restricted association facies overlying the biostorm. At the end of this period, the lagoon/restricted facies were spread in the studied area to mark the prograde stage B as sequence boundary type II.Third stage:- the sea level was raised from the northwest direction as open sea association facies, while to the southeast the biostorme and shoal facies was dominated. The first appeared for the shoal facies upon the open sea facies marked the mfs surface to start the final highstand deposition within the restricted and biostorm/shoal facies. This stage is represent the prograde stage C for the Mishrif Formation, where the deposition has ended to mark the unconformable surface (SBI) with Khasib Formation. http://ijaers.com/detail/stratigraphic-sequence-and-basin-development-of-the-mishrif-formation-in-selected-oil-fields-in-the-mesopotamian-zone-southeastern-iraq/ Madhat E.

This may resize behaviors in individuals and affect the perception of the subject in relation to themselves and others. New technologies, consumption and media influence shape and build the contemporary psyche. Thus, it becomes essential to consider the force with which the new messaging serving media plays in order to socialize and in the individual subjectivity.

In this context, Municipal Law 15,374 prohibited the free distribution of plastic bags in the city of São Paulo / Brazil, as of April 2015, and brought as an alternative the use of returnable bags and biodegradable bags in an attempt to reduce environmental impact caused by improper disposal of the plastic. Therefore, the purpose of this research was to analyze the impact of said Law on the reduction of the purchase of plastic bags made by the grocery retail in the city of São Paulo. A survey was conducted with data from two grocery retail stores in the city of São Paulo, between January and December 2015. The results showed that the implementation of the law reduced the volume of plastic bags provided by supermarkets without compromising the flow of people and financial income. http://ijaers.com/detail/impacts-of-the-plastic-bag-law-in-the-grocery-retail-in-the-city-of-s-o-paulo-brazil/ Karina Tonelli Silveira Dias, Acácia Ocerio da Silva, Wagner Luiz Lourenzani, Sergio Silva Braga Junior http://ijaers.com/uploads/issue_files/9-IJAERS-MAY-2018-7-Impacts.pdf The present study addresses the problems brought by the lack of preventive and corrective maintenance.

This study focuses on the Theory U, with the objective of studying the perception of stakeholders in the face of learning in the corporation. Its specific objectives are: (1) To raise stakeholders' perceptions regarding the learning tools and practices in the organization; (2) To characterize the possibility of organizational learning in the application of the Theory U; (3) Propose measures to modernize organizational learning tools and practices. The scenario is a military corporation in the Capital of Rondônia, Brazilian Amazon. The study of case method is applied, with procedures in search of qualitative and quantitative results. The collection of the stakeholders' perception was done through ethical protocol; interviews and in loco observation. A report was generated that points out the existence of a confrontation between corporate interests, indicating that managers do not promote the means to bring knowledge to their employees in the institution, while they become sceptical about their reality due to the emergence of a confrontation between theory and practice. The result suggests modernizing the organizational environment to support learning demands. It points that the tools and practices should be reoriented with the purpose of innovating the environment with organizational learning resizing, from now on to be integrative with new technologies, with collaborative focus, through redesigns of processes and procedures following advanced technological standards.

Measurements of the decision variables related to the routes, vehicles and passengers are made in order to determine the existing public transport system. These decision variables include the number of vehicles leaving service during the day, the passenger carrying capacity of the vehicles, the starting and ending times of the laps, the length of the public transport line, the number of laps made during the day, the number of passengers per vehicle, and the total number of passengers. By using these variables, the structure of the existing public transportation system is determined. Increasing the quality of public transport services in metropolitan cities and raising the quality of users in more economical conditions is only possible by incorporating business activities into an institutional structure, integrating public transportation enterprises into one and planning and managing them in a unified way.

This study was designed to determine whether this occurrence can have a severe impact to imbalance the daily nutrient intakes by the individuals in the mentioned social segment, which increase the tendency of having nutrition related chronic diseases. In a hierarchy range from junior executives to CEOs of private sector organizations, 800 individuals were selected by disproportionate stratified random sampling. Selected individuals are interviewed using a structured questionnaire to assess their daily food combinations and their consumed portion sizes. Frequently consumed meal combinations were then analyzed for their macronutrient composition, to compare with world Health organizations’ (WHO) Reference Dietary Intake (RDI) levels of nutrients. The results reveal of significantly (p<0.05) higher daily fat (45.3 ±1.7 g/day) and protein (65.2 ±1.4 g/day) intakes than the WHO recommendation levels and significantly (p<0.05) lower in dietary fibre (22.3 ±1.1 g/day) contents by selected participants. Carbohydrate intake (133.1 ±2.2 g/day) was higher than reference levels but was not significant (p>0.05). This indicates of a considerable risk for many individuals in the concerned social segment, of having non-communicable diseases, if observed dietary patterns are continued. http://ijaers.com/detail/investigation-of-daily-macronutrient-intakes-by-sri-lankan-managerial-level-employees-working-in-the-private-sector/ M.

The area of study is located in the Southern part of Iraq at Majnoon oil field, 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 consisting of thick layers of sandstone rocks and the lower ones is consisting 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 the Zubair Formation at Majnoon oil field is characterized by two horizons. The first is showing high resisitivity-high gamma ray which represent the upper part, while the lower part show low resisitivity-low gamma ray. There is a good reservoir horizon with high oil saturation (low water saturation) in this unit at the Majnoon oil field is appeared as a non-continuous horizon. The middle member is dominated by low resistivity-low gamma ray. The high percentage of water saturation in this unit caused the lack of clarity of the oil saturation, which appears in a narrow band. The lower member of Zubair Formation is distinguished by shale dominated rocks and poor sorted sandstone. This shows high resisitivity-high gamma ray. There are many sub horizons as bands within the lower horizon as high resistivity-low gamma ray.

This crop is extremely appreciated by the Brazilian population and an important source of protein. Usually the small farmers are responsible by the largest production of the bean in Brazil. This work deals with the analysis of the effect of different water regimes (35, 28, 21 and 14%) on the porous system of a soil cropped with two distinct cultivars (Campos Gerais and Tuiuiú). Soil water retention curve (SWRC) and its derivative were utilized with the aim of investigating the changes in the porous system. Pore size distribution was also evaluated. The experiment was carried out at a greenhouse and the soil water content for the different water regimes was monitored by means of a TDR. Four undisturbed samples were collected from each wooden bed (eight) for the physic-hydrical characterization. Discrepancies in the SWRC were noticed for the region of small pressure heads. Differences were not observed between bean cultivars to SWRC. However, the water capacity function was sensitive to show differences in the soil porous system due to the treatments and cultivars. The lowest water regimes promoted the highest volume of fissures (big pores >250 µm) and, consequently, the highest ones had the largest volume of storage pores (<25 µm). http://ijaers.com/detail/water-regimes-and-bean-cultivar-effects-on-the-soil-porous-system-characteristics/ Rafael Domingues, Luiz Fernando Pires, André Belmont Pereira, Eduardo Augusto Agonellos Barbosa, Luis Miguel Schiebelbein, André Carlos Auller http://ijaers.com/uploads/issue_files/19 IJAERS-MAY-2018-4-Water.pdf The cladding welding analysis with pulsed flux cored arc welding (FCAW) process, were carried over a AISI 1020 base metal (thickness 12,7 mm, width 63,5 and length 185mm) with an CA6NM steel wire with diameter of 1.2mm. Was performed only one weld cord in the flat position. For experimental design was used the method of Taguchi L9 to determinate the parameter to be analyzed through the application of the analysis of variance (ANOVA) method. The response signals in RMS (Root Mean Square) analyzed were the voltage, current and acceleration. The procedure is based on a non-parametric domain-selective ANOVA for functional data, which results in the selection of the intervals of the domain presenting the most statistically significant effects of each factor over the selected response signals. The statistical results presented by ANOVA show that not all the selected variables have influenced the results.

Part of these properties have online devices to do measurements while another part can only be measured in the laboratory, an activity that sometimes require more time than a production of one entire jumbo roll or generate waste until fix the production. The advantage to use mathematical modeling as the neural networks is the ability to 'predict' online the product final properties through the machine’s information such as speed, flow of pulp, coating weight and the quality of fiber as degree of refining and whiteness. One of the properties used for assessing the quality of paperboard is the mottling that describes a marbled appearance on the paperboard surface. Mottling is determined using the method STFI™ Mottling who is characterized by a coefficient of variation of reflectance or standard deviation - defined by the methodology of the equipment. This property when out of parameters affects the quality of the final printed package, giving unsightly appearance. The focus of this study is to determine parameters by mathematical modeling that influence the mottling in order to provide conditions for machine’s operators to perform the process, reducing the variation of this property and keep the values inside the specified limits. The model was developed from historical data of 6 months of paperboard machine operation. The results indicated that mottling is mainly influenced by the temperature of the dryer after coating process. Application—Statement: A further understanding of the mechanisms that cause mottling would help to optimize the paperboard quality. http://ijaers.com/detail/analysis-of-the-behavior-of-mottling-in-coated-board-using-neural-networks/ Danielle Garcia, Luiz Fernando de Lima Luz Junior, Osvaldo Vieira http://ijaers.com/uploads/issue_files/22-IJAERS-APR-2018-42-Analysis.pdf <p>In this study we investigate how environmental education can be connected with the regional sustainable development We perceive that the dialogues surrounding Environmental Education in formal education have been dividing opinions over the last two decades. This does not happen only in relation to the conceptual precepts, but mainly in relation to the field of activity. Our theoretical support comes from authors engaged with the Critical Environmental Education, signaling for the construction of what we call Reference Framework. Our research is developed from a qualitative perspective, having as a strategy the exploratory case study. For the analysis of the documents we make reference to the methodology of content analysis proposed by Bardin (2011) and reflective application of the Reference Framework. We argue that so far in Brazil, environmental education is divided into two major theoretical trends that reflect the practices of environmental educators. On the one hand, supporting a behaviorist / liberal / conservative tendency of Environmental Education (CARVALHO, 2001; GUIMARÃES, 2000; LOUREIRO, 2008), understand environmental practices from its immediate resolution dimension, focusing actions that situate environmental practices through changes in social behaviors, mostly promoted by environmental activism.

The methodology was observational, descriptive and transversal. The sample had 391 young people. The data collection instruments were the WHOQOL-Bref and a socioeconomic questionnaire. Resulting in a total average score of 52.37 points, the highest for the Social Relations Domain and the lowest for the Environment. When compared to the variables "Sex", "Income" and "Age", the one with the highest statistically significant association among the domains was "Income", followed by "Sex" and "Age". It was concluded that the QoL of young people is smaller when compared with other studies, being relevant investments in public policies. http://ijaers.com/detail/quality-of-living-perceived-of-the-young-people-of-the-vale-do-sinos-rs-brazil/ Gustavo Roese Sanfelice, Francieli Machado de Souza, Márcio José Testolin, Aline Belem Machado, Daiane Bolzan Berlese http://ijaers.com/uploads/issue_files/24-IJAERS-MAY-2018-20-Quality.pdf The objective of this article is to present, in the form of a bibliographic review, the main characteristics and functionalities of probiotics, highlighting their importance in the dietary management of country chickens and the innumerable benefits that the inclusion of this additive in the diet can provide for animal health. The use of antimicrobial additives (antibiotics) contributed to the development of industrial and colonial poultry; however, the reflection of the indiscriminate use of these additives has raised concerns regarding the development of bacterial resistance in birds. Probiotics emerged as a viable and reliable alternative, to promote sanitation and poultry production, which favored its application in the feeding management of large or small batches of poultry. http://ijaers.com/detail/characteristics-and-functionality-of-probiotic-bacteria-s-supplemented-in-the-ration-of-country-chickens/ Tony dos Reis Loss Franzin http://ijaers.com/uploads/issue_files/25-IJAERS-MAY-2018-12-Characteristics.pdf The water is an indispensable natural resource for life, economic development, and the conservation and maintenance of ecosystem services. It is known that the quantity and quality of water available for consumption is decreasing considerably and the increasing scarcity of this resource may be associated with factors such as the irregular distribution of water, waste and irrational use of it, socioeconomic and environmental problems, pollution of resources inadequate disposal of sewage, lack of basic sanitation and treatment of sewage, among others. In this way, the environmental problems have gained relevant space in the current discussions due to their importance, making the debates of these questions in the society necessary. Because of the anthropic activities that have been developed in a disorderly way and without planning, it reflects drastically in the environmental degradation, especially in this case, in the quality of the waters, which compromises this natural resource, whatever the purpose of its use. Thus, the objective of this work is to evaluate the water quality of Querer Beach in Santa Rosa-TO, promoting a water bathing condition study. Therefore, to investigate the effects of anthropogenic interferences on water quality, the water quality was evaluated by means of monitoring. The analyzes of the bathing conditions, show the percentages obtained for the situations in which the beach is classified as suitable for bathing, the investigations followed the criteria established by the CONAMA resolution nº 274/00. The water quality at a specific point of the beach was evaluated and monitored for a determined period of six weeks, and the microbiological indicator of water quality according to the Collilert technique according to the methodology described by Standard Methods was used as a parameter. In this way, it was possible to verify the tolerances of the Brazilian parameters for the water bathing conditions indicators of Querer Beach. http://ijaers.com/detail/evaluation-of-water-quality-for-water-bathing-conditions-on-querer-beach-in-the-municipality-of-santa-rosa-tocantins/ Rubens Oliveira Lustosa, Angelo Ricardo Balduíno, Diogo Pedreira Lima, Polyana Lopes da Silva http://ijaers.com/uploads/issue_files/26-IJAERS-MAY-2018-16-Evaluation.pdf The behavior of employees in the workplace is influenced by intervening variables, among them are the feelings, passions and emotions.

System stability can be assessed either by transfer function or by state-space method. Both will arrive at matrix transformation and further decision approach. Both can be considered for diagonalization of matrix. It is a proven fact that when the matrix is diagonalized the elements of the principle diagonal are the Eigen values and these Eigen values are closed loop poles from which stability can be assessed. The feature of such a diagonal matrix is that its principle diagonal elements contain gains of all the feedback paths. Singular value decomposition is used here for diagonalization. Singular value decomposition technique has been demonstrated by many authors but, application of PCA with Euclidian norm has not been paid attention so far. The systems numerical array is fed to a digital processing tool such as Mat lab and SVD-PCA (Singular Value Decomposition- Principal Component Analysis) is applied to determine the reduction of disturbance or noise and to provide minimum sensitivity and error correction.

Net of a single exception (a routine named "structure reduction"), the whole method is based on a series of harmonic transformations. The above-mentioned transformations, named CAT (the acronym stands for Cataldo Advanced Transformations), turn out to be nothing but inverse chord substitutions characterized by specific conditions and restrictions. The method arises from the analysis of a considerable number of chord progressions, devoting particular (although not exclusive) attention to traditional jazz compositions: in this regard, it is worth highlighting how a significant improvement of CAT has been achieved by conducting an extremely thorough analysis of the so-called LEGO Bricks (public domain harmonic patterns). http://ijaers.com/detail/music-algebra-harmonic-progressions-analysis-and-cat-cataldo-advanced-transformations/ Carmine Cataldo http://ijaers.com/uploads/issue_files/29-IJAERS-MAY-2018-27-MusicAlgebra.pdf The hearing protection of workers is of great concern to occupational health and safety professionals because of the irreversible damage caused by prolonged exposure to noise. This work seeks to determine whether the hearing protection equipment used in the construction industry today is adequate, considering that, in addition to the intense noise, other risk factors are present in the typical environment of a construction site. For this, a survey was conducted on how workers in the industry recognise and prevent exposure to noise and how they use hearing protection. Subsequently, laboratory experiments were used to study, how the main contaminants interact with the material of which this equipment is composed. In laboratory tests, both foam and silicone plugs gained weight when exposed to contaminants typically found in construction. This fact evidenced the need for training regarding the hygiene of hearing protectors. Regarding the performance of the foam earplugs in the tests, it was verified that, even though they went through the cleaning process, the equipment also increased in mass. This fact demonstrates that cleaning helps but does not eliminate the contamination of the hearing protection devices (HPD). Finally, it was concluded that the both types of earplugs are efficient in relation to noise attenuation and protection of the hearing of the workers. However, the way they are used and cleaned can influence the contamination of these protectors and the research detected both a lack of information from the manufacturers and little or no training of the workers. http://ijaers.com/detail/critical-evaluation-of-individual-hearing-protectors-of-workers-in-civil-construction/ Fernando B.

In this work, the possibility of applying these two coatings in the ABNT 52100 steel of a stretch bending roll, with the addition or not of an intermediate NiAl layer, using the thermal spray process HVOF (High Velocity Oxygen fuel), since this process has a small thermal input and allows the possibility of applying a great variety of coatings, including non-metallic ones. It was proposed to evaluate the performance of the samples in situations of high abrasive wear, also evaluating the role of the intermediate layer to improve adhesion of the coating to the substrate. For the evaluation of the resistance to abrasive wear and adhesive, the pin-on-disc tests (ASTM G99-17) and tensile tests (ASTM E8E8M-16a), respectively, were used. The surfaces of the samples were also evaluated by optical microscopy and electronic scanning. In addition, the hardness of each sample was also evaluated. With the tests, it was concluded that the samples with higher hardness and the presence of intermediate layerpresented faults in the interface of thesubstrate with coating, and the resistance to abrasive wear did not deviate much from the values in the literature. http://ijaers.com/detail/adhesive-and-abrasive-wear-resistance-evaluation-of-a-abnt-52100-steel-from-a-stretch-bending-roll-coated-with-wc-co-and-niccr-applied-by-the-hvof-process/ Wender Pereira de Oliveira, Pedro Américo Almeida Magalhães Junior, José Rubens Gonçalves Carneiro http://ijaers.com/uploads/issue_files/32-IJAERS-MAY-2018-13-Adhesive.pdf Resistance spot welding was used to joint AISI 316L austenitic stainless steel and AISI 1020 low carbon steel. During the welding process, temperature measurements were taken to obtain the temperature curves. Because of the different chemical compositions of the carbon steel and stainless steels, their thermal conductivity values are also different. Electrical resistivity is also an important parameter when carbon steel is spot welded to stainless steel. Differences in the thermal conductivity and in the electrical resistivity of metals lead to an asymmetrical weld nugget in the dissimilar joints. Dissimilar resistance spot welding can be more complex than similar welding due to different thermal cycle experienced with each metal. http://ijaers.com/detail/resistance-spot-welding-of-dissimilar-steels-temperature-curves/ Diego Fonseca Silva, Pedro Paiva Brito, Pedro Américo Almeida Magalhães Júnior, Thaís Roberta Campos http://ijaers.com/uploads/issue_files/33-IJAERS-MAY-2018-34-Resistance.pdf Obesity in school-aged children has reached epidemic levels, which is considered a chronic disease.

To increase the competitiveness of Brazilian companies to an international level, products must have high standards of quality and high added value. Thus, the mathematical modeling and simulation of industrial processes ensures the stability of production. This study presents the fit of mathematical models for the Oxygen Delignification process of eucalyptus pulp of the industry Klabin Monte Alegre. The mathematical model estimates the kappa number after the reactor, based on two kinetic models given by the literature, one of these models considers oxygen excess in the reaction medium. The models showed a mean relative error of 10 %. The adjustment of the kinetic parameters equations was done in Matlab software, using classical methods of optimization, such as BFGS, DFP, Steepest Descent, Gauss Newton, Simplex and Levenberg Marquardt. The models were incorporated in the commercial simulator CADSIM Plus to provide an optimization tool to the pulp industries. The simulator predicts the kappa number after the Oxygen Delignification reactor. The results of the phenomenological models indicate that possibly there is excess of oxygen in the reaction media. Only the model that considered the presence of the oxygen in the kinetic equation was able to be implemented in the simulator CADSIM Plus, generating consistent results, with an absolute error of ± 2 kappa number. Application: The kinetic model applied to the CADSIM Plus software in this study may be used to optimize the Oxygen Delignification process either by reducing chemical consumptions or by testing different process conditions without changing production.</p> http://ijaers.com/detail/modeling-and-simulation-of-an-oxygen-delignification-industrial-process-of-cellulosic-pulp-using-kinetic-expressions-and-the-software-cadsim-plus/ Viridiane Vianna, Carlos I.

On the basis of the long-term data of Baku meteorological station during 1830-2014, the water level changes in the Caspian Sea was analyzed, calculations on ground water level fluctuations on the sea influence zone with the application of the selected calculation method were performed. It was determined that due to the changes in the Caspian Sea level between-28,9 m (minimum) and -26,13 m (maximum) interval, the ground water tables at the 25 km influence coastal zone, changes between 0,5- 1,93 m. These values are less than an accepted for the zone value of hesk=2,2 m. An analysis of the data shows that due to the fluctuations, especially rising of the Caspian sea water level, the normal working regime of the hydro-reclamation network (collector and drainage system, different type of the irrigation canals and rivers) under operation have been disturbed in the side zones, including in Mugan-Salyan massive.

From these procedures the micronutrients are available for the seeds before and during the germination stages. One high challenge is make efficient these treatment processes and to ensure the adsorption and the incorporation of these micronutrients in the seeds and to improve its performance in the germination phase. In this work studies explored the optimization of the incorporation process and the characteristics of the zinc oxide clusters adsorbed on the surface of the seed. The results were associated with the agronomic responses during the germinations stages of the seeds of corn. The seeds were treated in suspensions containing different concentrations of nanoparticles of zinc oxide and during different treatment times. The adsorptions in the corn surface and the absorption of the nanoparticles for the inner of the seeds were studied together with its antibacterial characteristics and correlated with the germinations indicators. The results showed that is possible to incorporate nanoparticles of zinc oxide in inner of the seeds of corn and improve the germinations indicators. Antibacterial protection was aggregated on the seeds of corn. It´s possible to incorporate 0.280 mg of zinc oxide nanoparticle per seed mass in inner of seeds with the optimal treatment conditions with nanoparticle concentration of 50 mg/L in the suspension and with treatment time of 180 minutes.

Filter material which is widely used in Ä°skenderun is chosen for the freight. Highway, maritime and railway transport types are used in route scenarios. The costs of the route scenarios are calculated. Cost calculations are based on 5, 10 and 14 freight tonnage. For the value of the 5 ton freight is 40 000 TL, for the value of the 10 ton freight is 145 000 TL and for the value of the 14 ton freight is 250 000 TL. After the cost analysis is done, the most appropriate route for each province is selected and entered into the geographic information system (GIS). Thus, for freight from Iskenderun, the cheapest mode of transportation can be chosen. It is seen that railway and multimodal transport is widespread in general when the cheapest routes are examined.

This work gathers data from a study conducted in a slaughterhouse for birds in the production of turkey leg quarters. An improvement opportunity was identified in the water consumption of the sanguine fluid removal process of the turkey leg quarters with a particular technological chiller. The area of intervention was chosen because of its history of higher-than-expected water consumption in relation to the acceptable limit negotiated with the local Federal Inspection Service. The evaluated criteria were water flow per kilo of leg quarter and the structure of the adsorption equipment used in the industry. The results of these analyses were directly linked to water savings and changes in equipment, increasing knowledge about the implementation of cleaner production in the slaughterhouse industry, aligned to the continuous improvement of the process. The control of the water flow and the direct changes made in the chiller resulted in water savings of 83,435 L/week and 1,001,220 liters/year, based on the production of the slaughterhouse under study, in addition to savings of R$ 289.52 per week or R$72,959.04 per year. http://ijaers.com/detail/operational-improvement-of-a-chiller-to-reduce-water-usage-in-the-cooling-of-turkey-cuts/ Fernanda Bianchet, Pamela Fagundes, Debora Merisio, Josiane Maria Muneron de Mello, Francieli Dalconton, Sideney Becker Onofre http://ijaers.com/uploads/issue_files/48-IJAERS-APR-2018-16-Operational.pdf Solid waste management is one among the fundamental and essential services provided by municipal authorities in the developed as well as developing countries to keep urban areas clean.
