Published: August 2017

Uranium materials are needed for the uranium fuel production of research reactors and radioisotope. Before the uranium material is used, it is stored in the storage facility. One of the prerequisites for uranium material storage facilities is that it must be in the sub-critical condition. The purpose of this study is to analyze the criticality condition of uranium material storage facility located in PT. Inuki (Persero) and to ensure that the criticality condition is always in sub-critical state. Criticality analysis was performed using MCNP-5 program to determine the level of criticality of the three uranium material storage facilities at initial conditions and conditions after adding the storage racks. For analysing storage facilities 1 and 2, three scenarios of container on the storage rack formations were considered. Meanwhile, for analysing the storage facility 3, one scenario was considered. The results confirm that all strorages at initial condition and after adding storage racks formation were still in sub-critical condition (k-eff<1). These results are then used as the basis for the uranium materials management. It is also used as a basis for issuing an operational license by the nuclear energy regulatory body (BAPETEN).Keywords : criticality, uranium storage facility, k-eff ANALISIS KRITIKALITAS DI FASILITAS PENYIMPANAN BAHAN URANIUM DENGAN FORMASI PENGATURAN RAK. Bahan uranium dibutuhkan untuk produksi bahan bakar reaktor penelitian dan radioisotop. Bahan uranium sebelum digunakan terlebih dahulu disimpan pada fasilitas penyimpanan. Salah satu prasyarat fasilitas penyimpanan bahan uranium adalah fasilitas tersebut harus dalam kondisi sub-kritis. Bila kondisi kritis terjadi mengakibatkan proses fissi pada bahan uranium tidak terkendali, sehingga akan menimbulkan suhu yang sangat tinggi. Tujuan dari penelitian ini adalah untuk menganalisa kondisi kritikalitas dari fasilitas penyimpanan bahan uranium yang berada di PT. INUKI (Persero) untuk menjamin fasilitas tersebut dalam kondisi sub-kritis. Analisis kritikalitas dilakukan menggunakan program MCNP-5 untuk mengetahui tingkat kritikalitas dari tiga fasilitas penyimpanan bahan uranium untuk kondisi awal dan kondisi setelah ditambahkan rak penyimpanan. Untuk fasilitas penyimpanan 1 dan 2 dibuat tiga skenario pengaturan container pada rak penyimpanan, sedangkan pada fasilitas penyimpanan 3 dilakukan 1 skenario. Hasil ini menunjukkan seluruh fasilitas penyimpanan pada kondisi awal dan setelah ditambah rak penyimpanan dalam kondisi sub-kritis (k-eff<1). Hasil tersebut selanjutnya dipergunakan sebagai dasar untuk menyusun manejemen pengelolaan bahan uranium. Selain itu juga digunakan sebagai dasar untuk pembuatan ijin dari badan pengawas (BAPETEN).Kata Kunci : kritikalitas, fasilitas penyimpanan berbahan uranium, k-eff

PENGARUH PENGEROLAN PANAS TERHADAP KARAKTER PADUAN Zr-0,6Nb-0,5Fe-0,5Cr. Paduan Zr-0,6Nb-0,5Fe-0,5Cr hasil pengerolan panas telah diteliti karakternya. Tujuan penelitian ini adalah mendapatkan data pengaruh pengerolan panas terhadap karakteristik mikrostruktur, kekerasan dan fasa yang terbentuk dalam paduan Zr-0,6Nb-0,5Fe-0,5Cr. Proses pengerolan panas paduan Zr-0,6Nb-0,5Fe-0,5Cr dilakukan pada temperatur 800 oC dengan waktu penahanan (soaking time) 1,5 dan 2 jam dan reduksi ketebalan 5–25 %. Hasil penelitian menunjukkan bahwa paduan Zr-0,6Nb-0,5Fe-0,5Cr memiliki struktur Widmanstätten dengan evolusi mikrostruktur menjadi kolumnar terdeformasi dan batang pipih terdeformasi seiring dengan semakin besarnya reduksi ketebalan. Selain itu, semakin lama waktu penahanan pada temperatur 800 oC maka ukuran butir relatif lebih besar dan terjadi pembentukan fasa a-Zr dan Zr3Fe. Kekerasan paduan Zr-0,6Nb-0,5Fe-0,5Cr mempunyai kecenderungan yang sama yaitu semakin besar reduksi ketebalan maka semakin tinggi kekerasannya. Paduan Zr-0,6Nb-0,5Fe-0,5Cr mampu menerima deformasi besar berupa pengerolan panas dengan reduksi ketebalan 25 % dan terbentuknya fasa a-Zr dan Zr3Fe dapat meningkatkan kekerasan dan kekuatan paduan Zr-0,6Nb-0,5Fe-0,5Cr.Kata kunci: Paduan, pengerolan panas, reduksi ketebalan, mikrostruktur, kekerasan, fasa.

Published: August 2017

Experimental power reactor (RDE) which is planned to be constructed by BATAN is a kind of High Temperature Gas Cooled Reactor (HTGR) with 10 MWth power. HTGR is a helium gas-cooled reactor with TRISO-coated fuel that is able to confine fission products remained in the core. Although the fission products released into the environment are very small, in order to comply the regulations the study about environmental radiation on normal or routine operation condition need to be performed. Estimation of radiology in the environment involves the source term released into the environment under routine operation condition. The purpose of this study is to estimate the source term released into the environment based on postulation of normal or routine operations of RDE. The research approach starts with an assumption that there are defects and impurities in the TRISO fuel because of limitation during the fabrication. Mechanism of fission products release from the fuel to the environment was created based on the safety features design of RDE. Radionuclides inventories in the reactor were calculated using ORIGEN-2 whose library has been modified for HTGR type, and the assumptions of defects of the TRISO fuel and release fraction for each compartment of RDE safety system used a reference parameter. The results showed that the important source terms of RDE are group of noble gases (Kr and Xe), halogen (I), Sr, Cs, H-3, and Ag. Activities of RDE source terms for routine operations have no significant difference with the HTGR source terms with the same power.Keywords: routine discharge, radionuclide, source term, RDE, HTGR

Published: August 2017

Os problemas ambientais têm gerado novas oportunidade de negócios para as organizações, como a preocupação com a consciência ecológica e com o comportamento dos consumidores, que estão mais atentos às questões ambientais e sociais e às suas consequências. Assim, neste estudo quantitativo, a partir de um questionário adaptado da escala de Comportamento do Consumidor Ecologicamente Consciente (Ecologically Conscious Consumer Behavior) (ECCB)), de Straughan e Roberts (1999) e Lages e Vargas Neto (2002), teve-se como objetivo discutir os fatores que podem influenciar a consciência ecológica dos consumidores capixabas no momento em que estão realizando suas compras. Os principais resultados mostram que o novo modelo mental dos consumidores capixabas tem implicado a adoção de um comportamento verde somente para alguns hábitos. E quanto maior a escolaridade e a idade, maior a consciência ecológica dos consumidores. Já a renda não impacta tal comportamento, o que é bom para o Estado do Espírito Santo, que tem disparidades sociais e econômicas.Palavras-chave: Consumo ecologicamente correto. Marketing verde. Legislação. Abstract Environmental problems have generated new business opportunities for organizations, such as concern for ecological awareness and consumer behaviour, which are more conscious to environmental and social issues, and its consequences. Thus, this quantitative study, from the questionnaire of Ecologically Conscious Consumer Behavior of Straughan and Roberts (1999) and Lages and Vargas Neto (2002), aims to discuss the factors that may influence the ecological consciousness of consumers in the State of Espírito Santo when they are shopping. Findings show that consumers’ new mental model of this region has implied in adopting a green behavior only for some habits. In addition, the greater the education degree and age, the greater the ecological awareness of consumers. Income does not affect such behavior, which is good for the State of Espírito Santo, which has social and economic disparities.Keywords: Ecologically conscious consumer. Green marketing. Legislation.

Resumo Neste estudo teve-se por objetivo identificar quais os principais fatores de resistência estavam presentes no processo de implantação do Conhecimento de Transporte Eletrônico (CT-e) em duas grandes empresas de transportes de cargas da região de Chapecó, SC. A pesquisa classifica-se como qualitativa em relação ao problema e como descritiva quanto aos objetivos, empregando na coleta de dados um questionário padronizado aplicado aos administradores e contadores das duas transportadoras. Foi investigado sobre seis possíveis categorias de fatores de resistência na implementação do CT-e: poder institucional, insegurança ontológica, confiança, inércia, falta de conhecimento e aceitação de rotinas. As respostas coligidas demonstraram que dos fatores analisados somente o aspecto relacionado ao poder institucional não foi identificado como presente nas duas empresas por ocasião da adoção do CT-e e que houve maior resistência no âmbito administrativo, se comparado ao setor contábil dessas companhias. Como limitações, cabe apontar o fato de ter suas conclusões circunscritas à realidade das duas transportadoras e de abranger somente seis tipos de fatores de resistência.Palavras-chave: Fatores de resistência. Conhecimento de Transporte Eletrônico (CT-e). Transportadora rodoviária de cargas. Abstract The study aimed to identify what are the main resistant factors to the implementation of the Electronic Bill of Lading system (BL-e) in two big highway cargo shipping companies in the region of Chapecó, SC. The research can be classified as qualitative in relation to the problem and as descriptive in relation to the objectives, employing in the data collection a standard quiz applied to the administrators and accountants of two shipping companies. It was investigated about six possible categories of resistant factors to the implementation of the BL-e: institutional power, ontological insecurity, confidence, inertia, lack of knowledge, and acceptance of routines. The collected answers showed that from the analyzed factors only the aspects related to the institutional power were not identified as present in the two companies by occasion of adoption of BL-e that there was a great resistance in the administrative scope, if compared to the accounting sector of these companies. As limitations, it is worth pointing the fact of having their conclusions limited to the reality of the two shipping companies and including only six types of resistance factors.

Os consórcios empresariais portugueses: análise estatística da vertente económica
Authors: Machado de Almeida Bruno José 
Published: August 2017

As relações de colaboração entre as empresas são frequentes, sendo o modelo de cooperação um dos fatores mais determinantes. O seu pressuposto básico é, sobretudo, económico e enfatiza a otimização das sinergias em projetos partilhados. No entanto, os consórcios empresariais analisados contratualizam exclusivamente a vertente jurídica e organizacional e ocultam a vertente económica subjacente às alianças. Desse modo, o objetivo com este trabalho está centrado na procura e explicitação das componentes da dimensão económica que as empresas melhor identificam quando adotam a figura jurídica do consórcio empresarial. Para isso, foi construído um inquérito em escala Likert e remetido a um conjunto de empresas com acordos de cooperação, no sentido de indagar o pensamento dos seus responsáveis. Em seguida, as respostas foram submetidas a uma análise estatística apropriada (média, desvio padrão, testes de Kolmogorov-Smirnov, Shapiro-Wilk e Alfa de Cronbach, etc.). Os resultados obtidos sugerem que a inovação e a sustentabilidade são os fatores mais bem percecionados pelos consorciados.Palavras-chave: Cooperação empresarial. Economia. Eficiência. Internacionalização. Portugal. Abstract The relations of collaboration between the companies are frequent, and the model of cooperation one of the most crucial. His basic premise is mainly economic and emphasizes the optimization of synergies in projects that are shared. However, the business consortiums analyzed exclusively hire the legal aspect and organizational change and hide the economic aspect behind the alliances. To do so, we created a questionnaire in Likert’s scale which was given to companies with cooperation agreements to find out their managers’ thought. Subsequently, the answers were submitted to an appropriate statistical analysis (mean, standard deviation, Kolmogorov-Smirnov, Shapiro-Wilk and Alfa de Cronbach tests, etc.). The result suggests that innovation and sustainability are the factors most identified by the partners.Keywords: Business cooperation. Economics. Efficiency. Internationalisation. Portugal.

Published: August 2017

The widespread pornography has yielding enormous negative effects for especially women and their born children ranging from diseases, abortion, death, unhealthy sexual life, and so on. These excesses generate from the crisis of sexual ethics that degrade sexual acts as merely for temporary and biological objectives. Using both hermenutics and mainly discourse analysis, this paper seeks to find out the representation of sexual ethics in Qurrah al-‘Uyun and the ways subject being subjectivated in the discourse. This paper finds out that sexual regimentation in Qurrah al-‘Uyun is constituted based on the benefit of sexual act and its danger. The religious and medical precautions are established in order that subjects will follow the recommendations and avoid the cautions to hinder harmful effects the sexual acts may generate for them and their progeny. The goals of sexual acts, favorable times for progeny and pleasure and ritual for sexual acts are so much determined in line with natural, rational and religious arguments. Within this context, they have to apply self restriction and stylizing their sexual behavior according to the determined regimen either alimentary or sexual to gain benefit for future.Copyright (c) 2017 by KARSA.
