Published: November 2017

As indústrias de cal são caracterizadas pelas altas emissões de dióxido de carbono (CO2) na atmosfera. Isto se deve ao fato das indústrias atuarem com tecnologias ultrapassadas, resultando em alto consumo de combustível, baixa eficiências energéticas e grandes impactos ambientais. Para diminuir os danos ambientais causados pela indústria de cal é necessário o conhecimento do processo produtivo, das tecnologias empregadas e dos impactos ambientais. Por essa razão, este trabalho tem por objetivo fazer uma análise do processo produtivo da cal, desde as jazidas até o produto final, mostrando as tecnologias empregadas em cada etapa do processo.Palavras-chave: Indústrias de cal. Processo produtivo. Impacto ambiental.State-of-the-art on the manufacturing process of lime in mid west region of Minas GeraisAbstractThe lime industries are characterized by high emissions of CO2 in the atmosphere. This is because the industries are using outdated technology, resulting in high fuel consumption, low energy efficiencies and high environmental impacts. To reduce the environmental damages caused by the lime industry, it is necessary to know the manufacturing process, the technologies used and the environmental impacts. Therefore this paper aims to analyze the manufacturing process of lime, from the limestone quarries to the final product, showing the technologies used in each step of the process.Keywords: Lime Industries.

Usando splines cúbicas na modelagem matemática da evolução populacional de Pirapora/MG
Authors: Domingues José Sérgio , Gonçalves Marcela Carvalho , Braz Suélem Costa , Pereira Flávio Júnio
Published: November 2017

O objetivo desse trabalho é obter um modelo matemático para a evolução populacional da cidade de Pirapora/MG, baseando-se apenas nos dados de censos e contagens populacionais do Instituto Brasileiro de Geografia e Estatística (IBGE). Para isso, é utilizada a interpolação por splines cúbicas, pois as técnicas de interpolação linear e polinomial, e também o modelo logístico, não se ajustam bem a essa população. Os dados analisados não são equidistantes, então, utiliza-se como amostra anos separados com passo h de 10 anos. Os valores descartados inicialmente e as estimativas populacionais para esse município, descritos pela Fundação João Pinheiro, serviram para validação do modelo construído, e para a estimativa das diferenças percentuais de previsão, que não ultrapassaram os 2,21%. Ao se considerar que o padrão de evolução populacional de 2000 a 2010 se manterá até 2020, estima-se as populações da cidade de 2011 a 2020, cuja diferença percentual média foi de apenas 0,49%. Conclui-se que o modelo se ajusta muito bem aos dados, e que estimativas populacionais em qualquer ano de 1970 e 2020 são confiáveis. Além disso, o modelo permite a visualização prática de uma aplicação dessa técnica na modelagem populacional, e, portanto, também pode ser utilizada para fins didáticos.Palavras-chave: Splines cúbicas. Interpolação. Modelagem matemática. Evolução populacional. Pirapora.Using cubic splines on mathematical modeling of the population evolution of Pirapora/MGThe main objective of this paper is to obtain a mathematical model for the evolution of the population in Pirapora/MG, based only on data from censuses and population counts from Brazilian Institute of Geography and Statistics (IBGE). For this, the cubic spline interpolation is used because the technique of linear and polynomial interpolation, and also the logistic model do not fit well with this population. The analyzed data are not equidistant, then, it is used as sample, years apart with step h of 10 years. The values initially dropped and population estimates for this city, described by Fundação João Pinheiro, served to validate the constructed model, and to estimate the percentage differences of prediction, which did not exceed 2.21%. Considering that the pattern of population evolution from 2000 to 2010 will remain until 2020, it is estimated the population of the city from 2011 to 2020, whose average percentage difference was only 0.49%. The conclusion is that the model fits well to the data, and population estimates in any year from 1970 to 2020 are trustfull. Beyond, the model allows practical visualization of an application of this technique in population modeling, and therefore, it can also be used for teaching purposes.Keywords: Cubic splines.

CUDA vs. OpenCL: uma comparação teórica e tecnológica
Authors: De Paula Lauro Cássio Martins
Published: November 2017

Apresenta-se neste trabalho uma comparação entre duas arquiteturas para computação paralela: Compute Unified Device Architecture (CUDA) e Open Computing Language (OpenCL). Alguns trabalhos na literatura apresentaram uma comparação de desempenho computacional entre as duas arquiteturas. Entretanto, ainda não existe algum artigo recente e completo que destaca claramente qual arquitetura pode ser considerada a mais eficiente. O objetivo deste trabalho é realizar uma comparação apenas em nível de hardware, software, tendências tecnológicas e facilidades de utilização, evidenciando aquela que pode apresentar o melhor desempenho de uma maneira geral. Para tal, descreve-se os principais trabalhos que já fizeram uso de pelo menos uma das arquiteturas. Observou-se que, por ser um sistema heterogêneo, a escolha do OpenCL pode parecer mais óbvia. No entanto, foi possível concluir que CUDA, apesar de poder ser utilizada apenas nas placas gráficas da NVIDIA®, tem sido uma referência e mais utilizada ultimamente.Palavras-chave: CUDA. OpenCL.

To this end, we describe the main works that have used at least one of the architectures. It was observed that the choice of OpenCL may seem more obvious for being a heterogeneous system. Nevertheless, it was concluded that CUDA, although it can be used only in graphics cards from NVIDIA®, has been a reference and more used recently.Keywords: CUDA. OpenCL. GPU.

Authors: Moreira Bruno César de Melo , Costa Daniel Fonseca , Andrade Lélis Pedro , Pedrosa Guilherme Henryque
Published: November 2017

Este trabalho procurou investigar se a independência dos Conselhos de Administração apresenta-se como fator condicionante da estrutura de capital de empresas de capital aberto, transacionadas na BOVESPA. Para alcançar o objetivo proposto, utilizou-se da modelagem de dados em painel estimados a partir da abordagem dos Efeitos Fixos (EF) e dos Efeitos Aleatórios (EA), para um horizonte temporal compreendido entre 2007 e 2011. Para se mensurar a independência dos Conselhos de Administração, foram levantados e analisados os seguintes dados: tamanho do Conselho de Administração; se o presidente do Conselho de Administração e o presidente da empresa são pessoas distintas; e se o Conselho de Administração possui apenas membros externos. Com relação à estrutura de capital das empresas, definiu-se como variáveis a serem analisadas: a relação Capital de Terceiros e Capital Próprio; relação Capital de Terceiros/Passivo Total; relação entre Dívida Bruta e Patrimônio Líquido; e Dívida Total Bruta. Os resultados demonstraram que, no período analisado (2007 a 2011), em média, 40,49% das empresas estudadas possuíam seu Conselho de Administração caracterizado como independente. Entretanto, para o período em questão, o modelo de dados em painel não apresentou evidências que pudessem comprovar uma relação estatisticamente significante entre a independência do Conselho de Administração e a estrutura de capital adotada pelas empresas analisadas.Palavras-chave: Conselhos de Administração.

Estrutura de Capital.Board of directors’ independence and capital structure composition in firms listed: an analysis for BM&FBovespaThis work aims to investigate if the board of directors’ independence is one of the capital structure’s determinants in Brazilian listed firms at BM&FBOVESPA. To this end, we used Panel Data models using Fixed Effects (FE) and Random Effects (RE), during 2007 to 2011 period. To measure the board of directors’ independence we collected and analyzed data related to: Board’s size, duality of leadership between Chairman and CEO positions, and, if there is only outside members in Board of Directors. In regarding to firms’ capital structure, we defined as following: the debt/equity ratio, debt / Total Liabilities ratio; Relationship between Gross Debt and Equity, and Total Gross Debt. The results showed that in the period analyzed, we find, on average, that 40.49 % of the firms studied have characterized its Board of Directors as being independent; however, for the period deemed in this study, the panel data model suggests no evidence statistically significant in relationship between Board of Directors’ independence and Capital Structure for firms deemed in this study.Keywords: Boards of Directors.

Análise matemática de um modelo para crescimento de células-tronco cancerígenas em tumores
Authors: Gouvea Maria Elizabeth de , Santos Hoyama Maria , Fernandes Luís Ricardo , Duque Thais Oliveira
Published: November 2017

Apresenta-se um modelo matemático baseado na hipótese de que o crescimento de tumores tem sua origem nas células-tronco cancerígenas (CTCs). No entanto, o próprio conceito de célula-tronco cancerígena (CTC) tem sido alvo de controvérsias na literatura e uma das questões abertas à discussão se refere à proporção de CTCs em um tumor. O modelo apresentado, baseado no comportamento do sistema hematopoiético, tem uma estrutura hierárquica composta de dois compartimentos: o de células-tronco (CT) e o de células diferenciadas ou progenitoras (CPs). Admite-se que um tumor seja constituído por uma população de células que se tornaram anormais por adquirirem mutações durante o processo de mitose. Para o modelo matemático proposto, mostramos que as CTCs podem ser células anormais que residem no compartimento de células-tronco, mas também podem ser CPs que, através de mutação adquirida na mitose, se tornam capazes de se autorrenovarem. Mostramos, em concordância com resultados experimentais, que a proporção de CTCs em um tumor pode variar de acordo com a mutação que o originou. Nosso modelo sugere que os tumores mais agressivos são aqueles em que a proporção de CTCs é grande.Palavras-chave: Modelo matemático. Célula-tronco cancerígena. Tumor. Mathematical analysis of a model for the cancer stem cells growing in tumors We present a mathematical model based on the hypothesis that the growing of a tumor is driven by the cancer stem cells (CSC). However, the concept of CSC and the proportion of this subpopulation in a tumor remain as topics of considerable controversy. Our model, based on the known behavior of the hematopoietic system, has a hierarchical structure with only two compartments: one for the stem-cells (SC) and another for the differentiated or progenitor cells (PC). We admit that a tumor is constituted by a population of abnormal cells, that is, cells that, during mitosis, acquired a mutation. Our mathematical model suggests that a CSC can either be a cell residing in the stem cell compartment or a differentiated cell that, due to the mutation, became able of self-renewal. In accordance to some experimental results, our model shows that any proportion of CSC is possible in a tumor. However, the bigger this proportion is, the more aggressive is the tumor.Keywords: Mathematical model.  Cancer stem cell. Tumor.

A Reliable Measure of Information Security Awareness and the Identification of Bias in Responses
Authors: McCormac Agata , Calic Dragana , Butavicius Marcus , Parsons Kathryn , Zwaans Tara , Pattinson Malcolm
Published: November 2017

The Human Aspects of Information Security Questionnaire (HAIS-Q) is designed to measure Information Security Awareness. More specifically, the tool measures an individual’s knowledge, attitude, and self-reported behaviour relating to information security in the workplace. This paper reports on the reliability of the HAIS-Q, including test-retest reliability and internal consistency. The paper also assesses the reliability of three preliminary over-claiming items, designed specifically to complement the HAIS-Q, and identify those individuals who provide socially desirable responses. A total of 197 working Australians completed two iterations of the HAIS-Q and the over-claiming items, approximately 4 weeks apart. Results of the analysis showed that the HAIS-Q was externally reliable and internally consistent. Therefore, the HAIS-Q can be used to reliably measure information security awareness. Reliability testing on the preliminary over-claiming items was not as robust and further development is required and recommended. The implications of these findings mean that organisations can confidently use the HAIS-Q to not only measure the current state of employee information security awareness within their organisation, but they can also measure the effectiveness and impacts of training interventions, information security awareness programs and campaigns. The influence of cultural changes and the effect of security incidents can also be assessed.
Refugee Claims and Criminalization of Same-Sex Intimacy: The Case of Sebastiao
Authors: Hersh Nicholas
Published: November 2017

This article reviews the decision of Sebastiao v Canada (Minister of Citizenship and Immigration), in which the Federal Court upheld the decision of the Refugee Appeal Division (RAD) of the Immigration and Refugee Board (IRB) to reject Sebastiao's claim for refugee protection because his fear of persecution on account of his sexual orientation in Angola was not well founded. The case of Sebastiao attempted to advance the RAD's understanding of properly reviewing documentary evidence in refugee claims based on sexual orientation. The record included helpful resources like the United Nations High Commissioner for Refugees' Guidelines on International Protection No 9: Claims to Refugee Status based on Sexual Orientation and/or Gender Identity within the Context of Article 1A(2) of the 1951 Convention and/or its 1967 Protocol Relating to the Status of Refugees, international human rights cases setting out important legal principles, and published works of international legal experts on sexual minority refugees. Nevertheless, the Federal Court found that it was open to the RAD to expect proof that laws criminalizing sexual minorities are actively applied in Angola.

Layoutplanung und -umsetzung unter volatilen Materialflussumgebungen
Authors: Dombrowski Uwe , Ernst Stefan , Fochler Simon
Published: November 2017

Kurzfassung

Der Teiledienst des After Sales Service ist gekennzeichnet durch volatile Nachfrageschwankungen mit sporadischen und kaum planbaren sowie saisonal beeinflussten Kundenbedarfen. Folglich sind bei der Ersatzteil-Intralogistik volatile Materialflüsse bei gleichzeitig hohen Kundenanforderungen hinsichtlich Termintreue und Verfügbarkeit zu berücksichtigen. Für die Layoutplanung bedeutet dies eine erhöhte Unsicherheit und Komplexität. Ein Ansatz zum Umgang mit diesem volatilen Projektumfeld stellt die agile Methode Scrum dar. Es hat sich gezeigt, dass Scrum durch verschiedene Anpassungen erfolgreich in der Layoutfeinplanung und -umsetzung für die Ersatzteil-Intralogistik eingesetzt werden kann.

Published: November 2017

Background:

Papillary renal cell carcinoma (pRCC) is associated with EGFR expression and activation of MET signaling pathway. A randomized multicenter parallel two-stage phase II trial of MET inhibitor tivantinib alone or in combination with EGFR inhibitor erlotinib was conducted in patients with pRCC.

Methods:

Patients with advanced pRCC and 0-1 prior systemic therapy were randomly assigned to tivantinib 360 mg BID (Arm 1) or tivantinib 360 mg BID plus erlotinib 150 mg daily (Arm 2). Target max accrual was 70 patients (35 per arm) with interim analysis planned after enrollment of 20 patients per arm.

Results:

Six % of patients had type 1 pRCC, 42% had type 2, and 52% had no subtype assigned. The study was closed after the first stage when both arms yielded RR of 0%. Median progression free survival (PFS) was 2.0 and 3.9 months, and OS was 10.3 and 11.3 months in Arms 1 and 2 respectively. Treatment was well tolerated. Exome of tumor tissue from 16 patients were successfully sequenced using Agilent SureSelect probes. Only 1 of 16 samples harbored MET mutation. Other mutations associated primarily with type 2 pRCC were noted and included CDKN2A, PBRM1, SETD2, KDM6A, FAT1 and NF2.

Conclusions:

Tivantinib - either alone or in combination with erlotinib has no clinical activity in patients with advanced pRCC. The S1107 cohort had a low proportion of patients with MET alterations. MET remains a reasonable therapeutic target in pRCC, but selection of patient subsets exhibiting MET activation may be required to better benefit from therapy with MET inhibitors.
Non-Clear Cell Renal Cell Carcinoma: Current Management and Best Practice
Authors: Salgia Meghan , Adashek Jacob , Bergerot Paulo , Pal Sumanta K.
Published: November 2017

The treatment of metastatic renal cell carcinoma (mRCC) has evolved markedly over the past several decades; first with the introduction of targeted therapies and more recently with data supporting checkpoint inhibition. However, the vast majority of studies to date have explored the benefit of agents specifically in the context of clear cell disease. For the estimated 15–20% of patients with non-clear cell histology, there is little consensus around best practice. Herein, we discuss emerging datasets providing biologic characterization of non-clear cell RCC and identify trials that exploit this biology.

Published: November 2017

This experiment was conducted to evaluate the efficacy of garlic (Allium sativum) extracts supplementation in drinking water as a growth promoter of broiler chicken. A total of 60 one-day-old male Lohman meat broiler chicks were distributed over two groups of 30 chicks with three replicates of 10 birds. Group B was supplemented with garlic extract from water and Group A kept as a control. Weekly observations were recorded for live body weight gain up to 4th weeks and hematological tests were performed at 30th days. Live weight and weight gain of the treatment group were significantly (p<0.05) higher than that of the control group. Significant (p<0.05) higher values also observed in terms of weight of heart, liver, spleen, and pancreas for the treatment group. The value of TEC and PVC of treatment group showed significant (p<0.05) differences. The results suggest that better growth performance could be achieved in broilers with feed supplemented with garlic extract.Asian J. Med. Biol. Res. September 2017, 3(3): 317-322

Peste des petits ruminants (PPR) is a devastating and killer disease of domesticated small ruminants particularly goats. The present study was conducted on the serosurveillance of PPR in goats in different areas of Bangladesh. Blood samples were collected apparently from different years of age of goats in different areas of Bangladesh. All sera were subjected to serological test by competitive ELISA. For sero-surveillance of PPR virus total 200 serum samples were collected at different areas of Bangladesh such as Bogra18/60 (30%), Sirajganj 26/30 (86.67%), Mymensingh 5/50 (10%) and Rangpur 7/60 (11.67%). Among those 56 were seropositive and 144 were seronegative. The mean positive antibody titer ±SD of goat serum samples was 26.03 and the mean negative antibody titer was 77.76 The highest antibodies was detected in Sirajganj that was vaccinated flock whereas the lowest antibodies was found Mymensingh that was non vaccinated goat. It may be concluded that, in absence of vaccination, the presence of PPRV antibodies indicated that PPR viruses were circulating among the goats population but the vaccinated goat’s have protective level of antibodies against PPRV. So that preventive measures should be taken in goats against PPR virus by vaccination with proper maintain of cool chain.Asian J. Med. Biol. Res. September 2017, 3(3): 347-351

Published: November 2017

A 2.5 year old male horse was presented to Teaching Veterinary Hospital, VCRI, Namakkal, India with the history of lacrimation, impaired vision and progressive corneal opacity in left eye. Clinical examination revealed movement of a thread like worm in the anterior chamber of the eye. For removal of the worm, affected eye was prepared for surgery by deep sedation with xylazine hydrochloride. Then general anaesthesia was done with Ketamine hydrochloride and maintained by isoflurane. After induction, worm was removed by needling technique. Topical antibiotic and steroid were administered postoperatively to check secondary bacterial infection and corneal opacity. After surgery, the vision was restored and corneal opacity was reduced gradually. Morphologically, the worm was identified as Setaria spp. This is a common case in India due to vector prevalence.Asian J. Med. Biol. Res. September 2017, 3(3): 398-404

The study was conducted to investigate the heavy metal contamination in water, sediment and fishes from the Passur river in the Mongla port area near Sundarbans mangrove during the period from January to June 2013. The water samples were collected from five different sampling stations as St-1 (upstream- 1km upper from port area), St-2 (port area), St-3 (downstream-1km lower from port area), St-4 (tributary) and St-5 (1 km lower from tributary). Sediment samples were collected monthly from Station-1, 2 and 3 during the study period. The concentrations of heavy metals (Cu, Zn, Fe and Cr) in water were found from water much lower than the permissible level. The concentrations of five heavy metals (Cr, Cu, Ni, Pb and Fe) in the sediment samples were Fe at 23481.61 to 15339.4 mg/kg, while other metals were much lower and found little difference among different months. The result indicated that passerious pollution in the Passur river is due to heavy metals; whereas the concentrations of elements found could mainly be attributed to geological sources. To maintain the sound environment and healthy ecosystem of the river and the surrounding areas, need proper management and monitoring of water quality of the river.J. Environ.

The study was conducted to investigate the heavy metal contamination in fishes and shrimps from the Passur River near the world famous Sundarban mangroves located in the southwestern part of Bangladesh, during the period from January to June 2013. The fish (Liza parse) and shrimp (Penaeus monodon) samples were collected from two stations as St-1 (Katakhali-1 km upper from port area- upstream) and St-2 (Amtola-1 km lower from port area- downstream) monthly for three months in January (winter), March (pre monsoon) and May (Monsoon). Before analysis, a bit of muscle, the whole liver and two gill arches from each fish and shrimp were removed. Samples of tissues from each fish and shrimp were removed, weighed and dried. A microwave digestion system was used to prepare the samples for analysis. After digestion residue diluted with 25 ml 2.5% HNO3. The water used was deionized and distilled. The metal analyses of samples (Cd, Cr, Cu, Pb and Zn) were carried out by using UNICAM-929 atomic absorption spectrophotometer (AAS) in SGS Bangladesh Limited, Dhaka-1205, Bangladesh. Among the heavy metals studied Cd, Cr, Cu, Pb and Zn were detected in fish and shrimp species were within acceptable limits by FAO standards. The results of this study indicated that a general absence of serious pollution in the Passur River is due to heavy metals; whereas the concentrations of elements found could mainly be attributed to geological sources. In this regard, to maintain the water and sediment qualities as well as the sound and safe aquatic life of the river need proper monitoring and management by the relevant authorities of the Government of Bangladesh.J.

Fire safety and security system in high-rise buildings has been a significant issue from the last century. However, there are numerous provisions for safety measures from such fires and the magnitude and nature of the problem of this hazard has been unknown. This study identifies the location of high-rise buildings in Tangail pourashava through an extensive survey and then identifies the unique fire safety problems of those buildings and their associated fire risk. As it turns out, most of those buildings are highly vulnerable to fire risk due to lack of major fire fighting equipments and defiance of related laws and regulations. The study then addresses the means to provide fire safety in those buildings from both design and codes perspectives. It elaborates on the need to provide both building and occupant based protection to achieve the best results. It concludes with an overview of the special problems associated with high-rise buildings combined with specific use and occupancy-related requirements, employee training and response.J. Environ.

Published: November 2017

Salinity induced changes in root length and weight under salt tolerant condition. To examine the effect of different degrees of salinity on the root growth of rice, a total of 127 rice genotypes including mostly traditional, cultivated in the coastal regions of Bangladesh and some improved genotypes were used in the study. The study was conducted in petri dish providing 0, 6, 9, 12 and 15 dS m-1 (deci Siemens) salinity. Based on the performances, genotypes were scored and grouped as highly tolerant (score 1), tolerant (score 3), moderately tolerant (score 5), susceptible (score 7) and highly susceptible (score 9). Salinity stress reduced the root length and weight of rice genotypes. But the extent of root length and weight, varied with genotypes and levels of salinity. Generally in control condition root length and weight was found higher and it gradually decreased with increasing salt concentration. Based on decrease of root dry weight at 15 dS m-1 salinity, 8 genotypes scored 1, 28 scored 3, 40 scored 5, 35 scored 7, and 16 scored 9. Regarding root length, 14 genotypes were found highly tolerant, 18 were tolerant, 27 moderately tolerant, 38 susceptible and 30 were highly susceptible. Based on the score, the relationship between salinity level and tolerances of the different rice genotypes can be understood.J. Environ. Sci. & Natural Resources, 10(1): 45-53 2017

This study was carried out on estimation of inedible part (waste) of fruit and screening for potential pectin content (calcium pectate) in fruit wastes with respect to type, location and maturity. Fruit waste generation was significantly different in different fruit type, variety and maturity. In a whole fruit, amount of fruit waste (peel & core) was significantly higher than amount of fruit pulp. Among the waste evaluated the overall calcium pectate producing potential in order of merit were lemon, dragon fruit, guava, mango, jackfruit, banana, pomegranate, papaya, watermelon and pineapple. Unused fruit waste could be potential sources of pectin production.J. Environ. Sci. & Natural Resources, 10(1): 65-70 2017

The study examines the food security analysis of households of tribal people at three villages of Mohadevpur Upazila of Naogoan District. Data were collected from a random sample of 63 where the total tribal people were 252. A structured interview schedule and focus group discussion were used for collecting data during July to September 2016. Food security condition of households of tribal people was measured on the basis of their per capita calorie consumption per day. Pearson’s Product Moment Coefficient Correlation (r) was computed to explore relationship of the respondents’ selected characteristics and their food security condition. The major findings of the study were that education level, house land size, cultivable area, annual household income, training experience, credit received and perceived strategies to increase food security had significant positive impact on food security (calorie intake) but age had significant negative impact on their household food security (calorie intake). Most of the households were (71percent) moderately food secured, 21 percent household had food secured and 8 percent households were low food secured per year. Government and NGOs should provide various types of training on agriculture and non-agriculture of tribal people. Government should take some safety net programs during climatic events such as drought, river erosion etc. Government, different NGOs and development agencies should give attention to improve their income through adopting some income generating activities.J.

Harvesting is one of the major costs for rice production. Although the use of machine for harvesting rice in Bangladesh is increasing day by day and the machines are either combine harvester or reaper and thresher. Farmers of Bangladesh don’t have specific information to the choice of these machines. So to determine the cost of use of each machine, a study was conducted in Doyalsara, Bogra and Mymensingh region. Data were collected for rice in the Aman and Boro season of 2015 to determine the cost of harvesting by combine harvester and reaping and threshing by reaper and thresher. It was found for combine harvester operational cost and for carrying rice bag and straw to the plot side was Tk.10,447/ha. On the other hand, for reaper and thresher, the reaping, binding, carrying the rice to the plot side, threshing and cleaning required Tk.6,940/ha. The percentage of cost of combine harvester in relation to reaper and thresher for the same work is higher by 50.53%. In the socio-economic condition of Bangladeshi farmers, harvesting and threshing operations done by using self-propelled reaper and close drum thresher is cost effective and reasonable.J. Environ.
