The discovering process of new morbid genes and new target proteins for drugs have been shown to be very costly and laborious. Having in view cutting costs and speeding up this process, we propose, in this work, a new method to determine the gene druggability score and morbidity score, the probabilities of the protein encoded by the gene have the characteristics that make it a new target for drugs and in case of an alteration in that gene, we observed a phenotype that characterizes a genetic based illness. To determine these characteristics, we built, analyzed and determined the characteristics of the topology of the integrated molecular interactions network among human genes containing physical interactions between proteins, metabolic interactions and interactions of transcriptional regulation, and included other data such as level of gene transcription and cellular localization of the protein encoded by the gene. We tested our model in training sets and achieved results equal or better than the ones achieved by similar methods in the literature. Finally, with the purpose of investigating whether the assigned scores resembles the potential druggabilities and morbities of the previously unclassi ed genes, we looked for evidences in biomedical literature supporting the potential druggability and morbidity status of genes with the 10 highest scores. We found clear evidences for 73% and 90% of potential druggable and morbid genes respectively

Because of the constant increasing global competition, companies increasingly need to develop new competitive advantages and in this context a good logistics system can be both an opportunity for cost reduction and a differential on the client. The system starts at its base, which is formed by the inventory policies. These policies were created to address the strategic issues such as: How much to keep in inventory? How often placing orders? What is the optimal order size? This paper presents a model applied to a real situation of the industry in order to demonstrate the impacts of these policies on costs, as well as a literature review of existing literature related to the subject, for the construction limits and conditions of the model. By applying these concepts the model has been formatted and applied to three different policies, providing a simulation of the results. Finally a comparison is made between the three policies shown and the policy that bests fits the companies’ requirements is indicated

The civil construction is an industrial sector of great economic importance and that it comes exponentially growing in the country. However, this activity is deficient in its management processes, and in this context that the management of construction as a way of organizing and controlling all the technical and construction of an enterprise. The literature shows that the manager has a key role throughout the process of planning, execution and analysis of the results of the work being of prime importance that all steps have its due attention in order to avoid any technical problems or lack information. The management’s main objective is the transparency of technical and financial information to investors and their assessments of physical and financial performances of the work intervened positively in quality, deadlines and costs. In this sense, this paper aims to present consideration about the proper management of a residential development in vertical construction

The need for affordable housing and the high cost of today's building materials make necessary to look for useful and affordable technologies for these house buildings. In this context, this study aimed to evaluate the technical and economic feasibility of construction technology called Earthbag for use in public housing. Technical assessments were based on Kiffmeyer and Hunter's book (2004), academics dissertations and construction standards for the technology. The result allowed a positive evaluation towards the feasibility proposal and showing the possibility of replace the use of structural concrete blocks in public housing. The economic viability was performed an economical compared to a project Housing Project Bom Retiro 2 with one of Earthbag which have been shown considerable savings between the techniques. For the construction of masonry, build with purchased sand, 13% lower budget was found in comparison of a concrete masonry block. With the use of sand from the work site itself, there is a saving of 18%. Although earthbag has proven to be a technically and economically feasible for application in the construction of affordable housing, the shortage of technical and scientific studies and Brazilian regulations on this technology has limited its large-scale use

The building budgeting quickly and accurately is a challenge faced by the companies in the sector. The cost estimation process is performed from the quantity takeoff and this process of quantification, historically, through the analysis of the project, scope of work and project information contained in 2D design, text files and spreadsheets. This method, in many cases, present itself flawed, influencing the making management decisions, once it is closely coupled to time and cost management. In this scenario, this work intends to make a critical analysis of conventional process of quantity takeoff, from the quantification through 2D designs, and with the use of the software Autodesk Revit 2016, which uses the concepts of building information modeling for automated quantity takeoff of 3D model construction. It is noted that the 3D modeling process should be aligned with the goals of budgeting. The use of BIM technology programs provides several benefits compared to traditional quantity takeoff process, representing gains in productivity, transparency and assertiveness

O setor da construção tem evoluído ao longo dos anos, quer em termos de processos construtivos, quer em termos de materiais aplicados, tendo sempre em conta a relação custo/prazo/qualidade. Atualmente existe uma grande quantidade de edifícios cujo tempo de vida útil está a chegar ao fim e cujas estruturas e materiais se vêm a degradar progressivamente. É então necessário proceder à sua demolição e posterior construção de uma edificação nova ou então recorrer a processos de reabilitação, que visam conservar o património arquitetónico e procurar corresponder às solicitações e exigências regulamentares requeridas. Isto leva a outro ponto, que é a análise do investimento e a verificação da rentabilidade do projeto. A presente dissertação, inserida no Mestrado em Conservação e Reabilitação do Edificado, tem como objetivos fazer uma análise económica e financeira a vários edifícios intervencionados, verificando a viabilidade do projeto e determinando o período de retorno do investimento. O caso de estudo é um conjunto de quatro edifícios de custos controlados que foram reabilitados pelo exterior com o objetivo de melhorar o comportamento térmico, bem como as condições interiores das habitações, a nível de instalações e acústica. Por sua vez, os objetivos da presente dissertação incidem especificamente no isolamento térmico dos edifícios, na substituição das caixilharias e das janelas, das caixas de estore e dos estores. Foram realizadas medições de temperatura e humidade relativa antes, durante e após a reabilitação, através de um aparelho medidor Hygropalm, da Rotronic. Foram também registados os consumos energéticos (eletricidade, água e gás) antes e após a reabilitação. Posteriormente procedeu-se à análise e comparação de resultados em termos de custos para os moradores, bem como a análise de investimento para o dono dos edifícios. Foram também registadas as rendas que os moradores poderão pagar, estando divididas em três tipos: renda mínima, renda média e renda máxima e depois procedeu-se a uma análise financeira para cada uma delas. Considerando o investimento feito na reabilitação e analisando quatro cenários diferentes e sua receita respectiva (lucros expectáveis), sendo a receita correspondente à poupança energética e a cada tipo de renda, verificou-se que o investimento tinha retorno passados muitos anos.
