Authors: Barbosa Fabiana Maria , Martins Andre Rosa
Published: January 2021

This work discusses methods of preparing iron oxide for the Fenton reaction, using methylene blue as a model molecule. The solids were prepared by precipitation, complexation, combustion, and decomposition and characterized by Fourier transform infrared spectroscopy, X-ray diffraction, scanning electronic microscopy, energy dispersive X-ray spectroscopy, specific surface area measurement and were evaluated for methylene blue removal. The method influenced the structural and surface properties of the solids, and consequently the catalytic performance of the solids. The solid prepared by precipitation showed the highest area, amorphous phase, and the best performance in the adsorption test. On the other hand, the combustion method favored the formation of hematite and traces of magnetite.  The solid prepared by this method showed higher values of the methylene blue dye oxidation./Este trabalho discute métodos de preparação de óxido de ferro para a reação de Fenton, utilizando o azul de metileno como molécula modelo. Os sólidos foram preparados por precipitação, complexação, combustão e decomposição e caracterizados por espectroscopia de infravermelho por transformada de Fourier, difração de raios-X, microscopia eletrônica de varredura, espectroscopia de energia dispersiva de raios-X, medição de área superficial específica e foram avaliados para remoção de azul de metileno. O método influenciou as propriedades estruturais e superficiais dos sólidos e, consequentemente, o desempenho catalítico dos sólidos. O sólido preparado por precipitação apresentou a maior área, fase amorfa e melhor desempenho no teste de adsorção. Por outro lado, o método de combustão favoreceu a formação de hematita e vestígios de magnetita.  O sólido preparado por este método apresentou valores mais altos de oxidação do azul de metileno.

Authors: Silva Josemar Pereira da , Neto Márcio Ribeiro Vianna , Almeida Gustavo Matheus , Oliveira Eder Domingos de
Published: January 2021

Os mapas de curvas residuais são muito úteis para interpretar o desempenho da destilação azeotrópica de sistemas homogêneos. Esses mapas são obtidos através de um sistema de equações diferenciais, comumente resolvido em duas etapas, a saber, um equilíbrio líquido-vapor e um sistema de equações diferenciais. Uma solução alternativa trata ambas as etapas como um único sistema de equações. O objetivo do presente trabalho é comparar as duas abordagens de solução. Os sistemas ternários, nomeadamente etanol/metil-cicloexano/3-metil-pentano e acetato de etila/n-hexano/acetona, são usados para este fim. O coeficiente de fugacidade da fase de vapor foi calculado pela equação de Virial (truncada no segundo coeficiente), e o coeficiente de atividade da fase líquida, através dos modelos WILSON, NRTL, UNIQUAC e UNIFAC. Os resultados mostraram o potencial do método alternativo em comparação à abordagem convencional. Isso diz respeito ao tempo computacional despendido para a obtenção dos mapas das curvas residuais, igual a 4 e 25 segundos em média, respectivamente. Outra questão diz respeito à detecção da borda de destilação, que pode ser obtida sem o cálculo dos pontos de azeótropo.

Published: January 2021

Industry 4.0 is a topic little discussed today, especially in relation to the possible negative risks generated by it. In this way, this work aims to raise and discuss the risks of the Fourth Industrial Revolution currently found in the literature from a sustainability perspective and develop a theoretical framework to represent them. For this, a methodology of systematic analysis of the literature was used to relate the relevant works to the theme and thus to discuss them. Two databases (Scopus and Web of Science) were used in which 7772 articles were evaluated, of which 66 were used for the discussion. The 28 risks found were grouped into four dimensions (Economic Risks, Social Risks, Environmental Risks, and Technological Risks) where their relationships were studied and represent in the theoretical framework constructed. In this way, in addition to contributing to the academy building more theoretical contribution to the theme, the risks raised can help managers and companies to checkpoints of attention before implanting technologies and concepts of industry 4.0

Authors: Aquino Nayara Bach Franco de , Morais Daniel Branco de , Aquino Andriélli Corrêa de , Barbosa Graciele Vieira , Cavalheiro Alberto Adriano
Published: January 2021

There are several purposes for investigating hydrotalcite clays and one of them is due to its importance as an anionic adsorbent and ion exchanger, which make them capable of removing various pollutants from water. The most common hydrotalcite structure is based on double lamellar hydroxide of magnesium and aluminum, containing carbonate anions in the interlayer space. However, it is common to investigate the co-substitution of aluminum with other trivalent cations, especially transition metal cations, due to their binding properties. In this work, it was investigate the co-substitution of chromium (III) and aluminum in a sample of magnesium-aluminum carbonated hydrotalcite, comparing it with the same composition without this co-substitution. Thermal stability, crystallinity and morphology were investigated, showing that chromium contributes to the adsorptive capacity at low temperature.

Published: January 2021

Background: The intensive rearing systems of goats needs dietary formulations that will meet animal requirements, mainly the protein and energy to allow optimum growth rate. Alternative systems to attain 15-20 kg body weight by three months of age with better meat quality is need of the hour. Broiler goat production system is most suitable system of rearing for meat goat production. The current study was conducted to examine the impact of broiler goat production system on the carcass traits and meat quality characteristics of Malabari male kids. Methods: Fourteen pre-weaned kids were randomly allotted to two treatments. Treatment-I (T1) kids were allowed to suckle thrice a day during four weeks and twice in a day during consequent weeks. Whereas in Treatment-II (T2), kids were reared intensively by providing finely ground concentrate feed mixed with equal quantity of rice gruel from a feeding bottle after 7 days of colostrum feeding from the mother. The animals were slaughtered at an age of three months and the final body weight, carcass traits like dressing percentage, weight of different body parts and meat quality parameters like pH, color, cooking loss and shear force were analysed. The proximate composition and sensory evaluation was performed. Result: Broiler goat production system could produce significantly (P less than 0.01) higher final average body weight compared to natural system. All the carcass traits were significantly (P less than 0.01) higher in T2. The broiler goat production system could double the net live weight during the same period compared to natural suckling system with higher dressing % and the chevon produced was tender with less cooking loss. Hence, this system can be recommended for chevon production in shorter period with higher dressing % and lesser cooking loss in Malabari male kids.

Background: The Ultrasonograph of spleen in live goats were studied using a convex probe 2.5 to 5 MHz Colour Doppler Mylab onevet (e-saote) German Ultrasound Scanner in Veterinary Clinical Complex, Veterinary College and Research Institute, Namakkal. Methods: The extent of spleen in live goats when examined by USG revealed differences from the usual gross anatomical observations made in the embalmed or exsanguinated goats. The parietal surface of spleen was in direct contact with the pulmonary diaphragm while the ventral visceral surface lay over the cranial part of dorsal sac of the rumen. Result: The capsule was highly echogenic while the parenchyma consisted of numerous weak echoes distributed homogenously. The splenic vessels were anechoic with hyperechoic walls and appeared as longitudinal or cross sections. The greatest length was found at 11th intercostal space during the post-natal age of three to five months which was about 6 cm. The greatest length was found at 10th intercostal space during the post-natal age of eight to twelve months which was about 7 cm. The greatest length was found at 9th intercostal space during the post-natal age above one year which was about 9 to 15 cm. During the post-natal age above one year the smallest length was found to be behind the last rib which was about 4 cm in adult goats.
Social capital for socio-economic mobility of disadvantaged women: Limitations and opportunities connected to diversity in social networks
Authors: Boyagoda Kumidika
Published: January 2021

Using a differentiation between â€˜social supportâ€™ and â€˜social leverageâ€™ networks, this paper emphasizes recognizing the heterogeneity of social capital when considered a tool for upward socioeconomic mobility of women. The specific aims are to: a) asses if types of social capital women have access to, is similar; b) examine whether access to different types of social capital is connected to demographic and socioeconomic characteristics; and c) analyse the implications of different types of social capital on socio-economic mobility. The paper is based on quantitative and qualitative data from a purposive sample covering urban, rural and estate sectors in Sri Lanka. A survey of 534 women and in-depth interviews with 32 women were used for data collection. Ninety-nine percent had support networks, but less than half had leverage networks. Women with primary or no education/ in the poorest income group/in lower-level jobs had lesser access to leverage networks compared to the rich/ tertiary or higher educated/professionals and managers. The role played by leverage networks for women originating from lower socioeconomic strata to achieve upward mobility were clear. Leverage networks provided advice and information on financial management and physical asset acquisition, skill development and training, finding stable employment etc. which facilitated upward mobility.
Charity, Philanthropy and Development in Colombo: An Overview of a Research Project
Authors: Stirrat Roderick
Published: January 2021

This paper is a history of a developmentlinked research project into philanthropy in Colombo. It presents the background to the research, considers the reasons for the project being designed in a specific way, and summarises the conclusions the researchers arrived at. Whilst being of interest in themselves, the argument of this paper is that it is doubtful whether the research conclusions have had or will have any major impact on development practice nor have they contributed much if anything to poverty alleviation which was the desired impact of the project as far as the funder was concerned. This raises the more general question what are the preconditions which would lead to academic research having a more effective role in development.

Published: January 2021

This study aimed to understand the reasons that encouraged student teachers who are following the Bachelor of Education (B.Ed.) Degree at the Faculty of Education, University of Colombo to join the teaching profession. A purposive sample of thirty undergraduates were selected for study. Data gathering was done using semi-structured interviews. The reasons presented by the student teachers were categorized into intrinsic, extrinsic and altruistic reasons. Belief in oneâ€™s personal characteristics as being suited for a career in teaching and personal interest were among the intrinsic reasons identified. Extrinsic reasons included reasons such as admiration for the physical appearance of teachers, social position attributed to teaching as a â€˜nobleâ€™ profession, secured job with an adequate income, opportunities offered for career advancement and benefits for a balanced family life. Altruistic reasons were among the least mentioned reasons. Some participants mentioned a desire to contribute towards the wellbeing of children. The study also found that joining the B.Ed. programme with the sole intention of securing a job could lead to the recruitment of less suitable (though qualified) individuals to the profession. The findings of this study could be used to increase the quality of the process of producing and recruiting teachers.

Preço de transferência em empresas exportadoras brasileiras: adoção para avaliação de desempenho financeiro de divisões
Authors: Schafer Joice Denise , Gasparetto Valdirene , Ferreira Luis Felipe
Published: January 2021

Este estudo tem o objetivo de verificar fatores contingenciais que levam empresas exportadoras brasileiras a utilizar preço de transferência com abordagem gerencial. Pesquisa de levantamento foi realizada com noventa empresas exportadoras brasileiras, sendo aplicada aos dados a análise fatorial e a regressão logística. Os resultados mostram que, para a amostra, os fatores contingenciais investigados - descentralização, tecnologia, estratégia, tamanho da empresa e estabilidade do ambiente – não apresentaram relação significativa com o uso de preço de transferência, revelando que, mesmo empresas que adotam, normalmente empregam métodos que não permitem avaliação do desempenho financeiro das divisões. Apesar da relevância deste instrumento, mencionada pela literatura pesquisada, ele é pouco empregado na prática das organizações brasileiras pesquisadas, o que pode ser decorrente do uso de outros indicadores, e não o resultado financeiro das divisões, para avaliação do desempenho dessas unidades descentralizadas.

Este trabalho descreve e analisa os elementos potencialmente desencadeadores da Síndrome de Burnout na profissão médica, baseando-se na teoria da Psicodinâmica do Trabalho e na percepção dos profissionais que atuam no serviço de atendimento de urgência e emergência de Belo Horizonte. A pesquisa descritiva de abordagem qualitativa foi realizada com 10 médicos, que responderam a uma entrevista estruturada baseada na teoria da Psicodinâmica do Trabalho e no instrumento de pesquisa MBI (Maslach Burnout Inventory). Os dados submetidos à Análise de Conteúdo categorial indicam risco de acometimento pela Síndrome devido a: intensa pressão no trabalho; rotina intensa e exaustiva; imprevisibilidade do trabalho; rigor no cumprimento da escala de plantões; inadequação e escassez de equipamentos; condições inadequadas e inseguras para realização do trabalho; falta de segurança pública na execução do trabalho externo. No que tange às dimensões da Síndrome de Burnout, os riscos decorrem de: grande esforço físico, emocional e relacional; sentimento de exaustão, desgaste e angústia; recorrente ideia de abandono da profissão; absorção de sentimentos negativos que emergem do relacionamento com o paciente; medo de não conseguir fazer o que é demandado; sentimento de que a remuneração não é compatível com a expectativa e esforço profissional.
Innovative organization dimensions and the adoption of modern management accounting practices
Authors: Frigo Souza Fabiana , Gasparetto Valdirene
Published: January 2021

Purpose: The objective of this study was to analyze the relationship between the innovative organization dimensions and the adoption of modern management accounting (MA).Design: A sample of 79 companies, obtained through a survey, was submitted to descriptive analysis, exploratory factor analysis and logistic regression.Originality: The studies that evaluated the relationship between innovation and management accounting sought to verify how MA practices influenced the innovation capacity of organizations. This work seeks a relationship in another sense, based on the premise that innovations influence the way in which MA is designed.Findings: The results indicate a more intense usage of the traditional second stage MA practices. Regarding to modern MA practices, it has been identified that the innovation dimensions that influence its adoption are people, environment, team work and organizational structure, and these dimensions are those that have a significant relationship with the adoption of these practices, indicating that innovation may be a factor influencing the adoption of modern MA practices.Theoretical contributions: Research on the topic has identified factors that may influence the adoption or diffusion of modern MA practices, such as decentralization and the size of the company. In this regard, it is possible to see that in addition to these factors already identified, innovation, through the dimensions analyzed, may be another factor that influences the adoption of modern MA practices.

Conditions d’élevage des palmipèdes à foie gras : des demandes sociétales à une démarche de progrès
Authors: LITT Joanna , LETERRIER Christine , FORTUN-LAMOTHE Laurence
Published: January 2021

La pratique du gavage des palmipèdes consiste à introduire un tube (embuc) dans l’œsophage des animaux pour y déposer de l’aliment en quantité croissante afin de produire du foie gras. Cette pratique est remise en question et fortement contestée par des associations de protection animale et une partie de la société. En l’absence d’une alternative efficace, elle reste toutefois la seule façon de produire du foie gras à grande échelle, produit auquel reste attachée une majorité de français. Cette synthèse replace la production de foie gras au sein des questions sociétales autour du bien-être des animaux et fait le point sur les données scientifiques sur l’impact du gavage au sens large (introduction de l’embuc, charge alimentaire, mode d’hébergement) sur différents indicateurs de l’état de l’animal. Il apparaît ainsi notamment que i) le gavage et l’hypertrophie hépatique ne sont probablement pas nociceptifs en conditions normales de gavage ; ii) les animaux sont sensibles à la capture et à la contention ; iii) la fonction hépatique et la structure histologique sont préservées et l’hypertrophie hépatique est réversible ; iv) le gavage induit des modifications comportementales : augmentation de la fréquence d’abreuvement et de halètement sans apparition d’hypoxie ; diminution de la fréquence du toilettage ; v) ces comportements varient par ailleurs en fonction des conditions climatiques et de la configuration des logements ; vi) le gavage peut générer des blessures spécifiques (blessure de l’œsophage) lorsqu’il est mal réalisé et les conditions d’hébergement des animaux tendent à aggraver les lésions préexistantes (lésions des pattes) ; vii) la mortalité augmente pendant la période de gavage. Cet article synthétise aussi les connaissances et ressources disponibles pour mettre au point une méthode d’évaluation de l’état de l’animal, qui soit multicritère, adaptée aux palmipèdes pendant la phase de gavage et utilisable en ferme. Une telle évaluation permettrait d’objectiver l’état de confort ou d’inconfort des animaux et d’accompagner la filière de production de foie gras dans une démarche de progrès.

Published: January 2021

The study aims to identify the difference in communication needs of women giving birth and women during puerperium. An additional goal includes the analysis of the experience and communication needs through the context of a woman's approach to childbirth. The study is a prospective, cross-sectional, self-report survey. 521 women between 5 and 10 days after birth participated in the study. Women perceived information provided by the medical staff as the most helpful aspect of verbal communication both during labour and puerperium. Maintaining eye contact with the medical staff was perceived as the most helpful aspect of non-verbal communication. Women were more satisfied with communication during labour and birth than in the maternity ward and those after non-instrumental childbirth were more satisfied with communication compared to the instrumental birth group. Women perceiving childbirth as the natural, physiological process considered verbal and non-verbal communication during and after childbirth as less helpful than women perceiving birth as more risky and requiring interventions. The results of the study emphasize the importance of verbal and non-verbal communication during birth and puerperium and different communication needs during labour and early postpartum. It also showed that women who perceive labour as a physiological process seem to be less dependent on the communication with the medical staff than women who accept medical interventions during labour and birth as necessary.
The Dead-Alive Physicist Gedankenexperiment Debunked
Authors: Pushp Amal
Published: January 2021

We refute a recently proposed thought experiment namely the Dead-Alive Physicist (DAP) whose authors claim it to be the falsification of the von Neumann interpretation in Quantum Mechanics. We discover major flaws in their model and our justification serves the purpose of disregarding further claims and assertions made in the paper at various stages. Thus, in a yet another situation, it is proven that the formalism advanced by von Neumann is non-trivial and non-falsifiable.

Published: January 2021

Pigeons have accompanied humans since ancient time because they are used as a source of food, pets, hobby, and religious symbols. Pigeons have shown high prevalence rate of infection with gastrointestinal helminths and protozoan. This study was conducted to evaluate the prevalence of parasitic infections in the domestic pigeon (Columba livia domestica) from October, 2017 to April, 2018, purchased from bird market of Zakho City, Kurdistan region. The samples were taken from 50 adult pigeons (28 males and 22 females). The birds were transferred to Parasitology Laboratory, Faculty of Science, Zakho University. In the laboratory, each bird was sacrificed and immediately the feather and skin of under wings, chest and the rest of the body was examined for ectoparasites. The collected ectoparasites were preserved in 70% alcohol for further study. The sacrificed birds were dissected and their intestine and contained were examined for the presence of parasites. The results revealed a total rate of 76% of infection with ectoparasites, which included three species of lice, namely: Columbicola columbae (56%), Companulotes compar (36%) and Hohorstiella lata (10%). Regarding helminths, cestodes were the only helminths found in this study with a rate of 16% (8/50). Three species of cestodes were recorded, they included: Raillietina cesticillus(14%), Raillietina echinobothrida(4%) and Choanotaenia infundibulum (2%). Further studies are required to evaluate the effect of the recovered parasites on this host and their transmission to other poultry flocks and human.

Authors: EL-Sheekh Mostafa Mohamed , Dewidar Samha , Hamad Azza
Published: January 2021

Light is an important factor that influences the growth and photosynthetic efficiency of microalgae; however, little is known about how light intensity together with the wavelength affect the photosynthetic capacity and growth of marine microalgae. In the present study, the growth of the marine green microalga Dunaliella parva was studied and optimized under different light intensities (25 ~ 70 μmol m-2 s-1) and qualities (blue, green, and red) in comparison with white light at 40 μmol m-2 s-1 as a control. The growth was monitored by counting the cell number, pigment content, Chl a, Chl b, and carotenoids concentrations. The optimal growth and highest photosynthetic efficiency (Fv/Fm) were recorded at a light intensity of 40 μ mol m-2 s-1, white light, and 1.25 M NaCl (1.47 and 0.678×106 cell mL-1, respectively). The activity of antioxidant enzymes, including catalase and peroxidase, as well as ascorbate content, showed the highest values of 0.190 µM/min.mg Chl, 0.434 and 13.3 mg/g f.wt. respectively, under the green light, which confirmed the presence of environmental stresses.

A New Methodology to Find Private Key of RSA Based on Euler Totient Function
Authors: Somsuk Kritsanapong
Published: January 2021

The aim of this paper is to present a new methodology to find the private key of RSA. A new initial value which is generated from a new equation is selected to speed up the process. In fact, after this value is found, brute force attack is chosen to discover the private key. In addition, for a proposed equation, the multiplier of Euler totient function to find both of the public key and the private key is assigned as 1. Then, it implies that an equation that estimates a new initial value is suitable for the small multiplier. The experimental results show that if all prime factors of the modulus are assigned larger than 3 and the multiplier is 1, the distance between an initial value and the private key is decreased about 66%. On the other hand, the distance is decreased less than 1% when the multiplier is larger than 66. Therefore, to avoid attacking by using the proposed method, the multiplier which is larger than 66 should be chosen. Furthermore, it is shown that if the public key equals 3, the multiplier always equals 2.

THERMODYNAMIC, THERMAL AND ELASTIC PROPERTIES OF TITANIUM NITRIDE TiN: COMPARISON OF VARIOUS DATA AND DETERMINATION OF THE MOST RELIABLE VALUES
Authors: Kozma Anton
Published: January 2021

The analysis of literary data on thermodynamic, thermal and elastic properties of titanium nitride TiN which included values Debye temperature θD, volume coefficient of thermal expansion αV and bulk modulus B under standard conditions is carried out. It has been shown that the known data have a significant spread of values from 20 to 43 %. The 8 most rational variants of optimizing calculations are proposed, which make it possible to reveal the most reliable values of some TiN parameters. At the same time, the minimum and maximum values of θD and αV were used from literary sources, as well as the least contradictory data on isobaric heat capacity Cp, melting temperature Tm.p and density d of TiN. To improve the calculated results, the values of θD(TiN) determined using the methods of Magnus ‒ Lindeman and Debye were also used. The Mayer’s relation was the basic test expression. The obtained values of the bulk modulus were compared with the literature data. This made it possible to distinguish the least and most reliable values of αV and θD, as well as make a refinement correction for the last value. As a result, it was found that under standard conditions, the value of θD(TiN) close to the optimal should be within 746‒769 K, and for its isochoric heat capacity CV ‒ in the range 36.55‒37.19 J/(mol×K). The range of values, after optimization, does not exceed 3 %, unlike the 20 % available in the literature. A more accurate definition of Debye temperature for TiN needs to radically refine the values of its αV and B

Published: January 2021

This descriptive review presents current knowledge about the bioengineering use of a zirconium dioxide, the advantages and disadvantages of the material, and the prospects for research in this direction. The work reflects the success of the practical application of the zirconium dioxide as a material for dental structures and biological implants. Such practical characteristics, such as color-stability, chemical stability, good aesthetics, biocompatibility and durability, allowed to actively use the zirconium dioxide as a material for producing various dental structures. In comparison with other ceramics, the presence of high-performance of strength and fracture toughness of the zirconium dioxide enables the use of this material as an alternative material for the reconstructions in the readings with considerable loads. High hardness determines the zirconium dioxide as an excellent material for articular prostheses, because of its hardness, provides a low level of wear and excellent biocompatibility. However, along with positive characteristics, a widespread practical problem of using the zirconium dioxide in dentistry is a chip or fracture of veneering ceramics. It has also been reported that there is a shortage of orthopedic implants such as hydrothermal stability. The solution of such problems is indicated and the use of composite materials based on the zirconium dioxide, which allows to solve a similar problem, as well as to increase the service life and reliability of orthopedic implants by providing a higher fracture toughness and mechanical strength. The existence of such composite materials based on the zirconium dioxide provides a significant increase in the wear resistance of orthopedic implants, which is essential for successful prosthetics
STUDY OF POSSIBILITIES OF JOINT APPLICATION OF PARETO ANALYSIS AND RISK ANALYSIS DURING CORRECTIVE ACTIONS
Authors: Haievskyi Volodymyr
Published: January 2021

Continuous improvement in the quality management system is based on corrective action. Corrective actions require the identification of priority defects that require priority elimination of the causes of occurrence. The traditional method of prioritization can be considered a Pareto chart, built by the number of identified inconsistencies. This technique makes it possible to prioritize the most frequently detected defects. However, defects that are rare can significantly outweigh those that are often encountered in their consequences. The defect risk is a complex indicator that simultaneously takes into account both the number of detected defects and their impact. Failure Mode and Effects Analysis (FMEA) can be used to quantify risk. This technique allows to determine the risk priority number (RPN), taking into account the number of detected defects (O), the consequences of the appearance of a defect (S) and the possibility of timely detection of a defect or cause before the onset of undesirable consequences (D). The priority number of risks numerically characterizes the risks of a defect and can be used as a criterion for determining priority defects. Based on the values of the priority number of risks, a Pareto chart can be built and defects that form 80% of the risk area can be identified. These defects require urgent corrective action. According to the data taken from production, it is shown that the Pareto analysis by the priority number of risks gives results that differ from the analysis by the number of identified inconsistencies. Application of the proposed approach will allow introducing risk-oriented methods into the procedures for carrying out corrective actions. This will make it possible to direct the resources of the enterprise to eliminate the causes of defects that are actually detected and can have the most significant consequences for consumers of products

Published: January 2021

Activated carbon is a black color solid compound which is fabricated using naturally occurring materials such as woods and species of coal that composed of the majority in carbon. The activated carbon is highly remarkable compound in the catalytic activities in most of chemical industries and water treatment activities because of the significant performances of such activated carbon due to the sufficiency of the surface property which is called as the adsorption with the couple of high porosity. The manufacturing of activated carbon from disposable coconut shells and the investigations of the physic-chemical characteristics of such activated carbon were the expectances of the existing research. Domestically collected coconut shells were burnt in the range of different temperatures 390°C–300°C after removing unnecessary constituents. The chemical composition of the powdered activated carbon was inspected using an X-ray fluorescence (XRF) spectrophotometer and the surfaces of prepared activated carbon were examined using an optical microscope. As the outcomes of the above experiments, it seems that the most adequate burning temperature for the manufacturing of that batch of coconut shells was in the range of 330°C–350°C, 68.85% of ferrous and 31.15% of potassium as the composed metallic element apart from the non metallic carbon and the pure black color non- composite surfaces were observed under the microscopic studies. It is encouraged to develop this production using cost effective materials such as the shells of fesults which are belonging to the palm cast while utilizing the productions through the various applications in chemical industries
