Kitchen robot prod. line development. Proj. of Bowden cables cutting and thermal forming machine.

This document presents particular description of work done during student’s internship in PR Metal company realized as ERASMUS PROJECT at ISEP. All information including company’s description and its structure, overview of the problems and analyzed cases, all stages of projects from concept to conclusion can be found here. Description of work done during the internship is divided here into two pieces. First part concerns one activities of the company which is robotic chefs (kitchen robot) production line. Work, that was done for development of this line involved several tasks, among them: creating a single-worker montage station for screwing robots housing’s parts, improve security system for laser welding chamber, what particularly consists in designing automatically closing door system with special surface, that protects against destructive action of laser beam, test station for examination of durability of heating connectors, solving problem with rotors vibrations. Second part tells about main task, realized in second half of internship and stands a complete description of machine development and design. The machine is a part of car handle latch cable production line and its tasks are: cutting cable to required length and hot-forming plastic cover for further assembly needs.

Health-Related Quality of Life Impact of a Triple Combination of Olmesartan Medoxomil, Amlodipine Besylate and Hydrochlorotiazide in Subjects with Hypertension

BACKGROUND: A post-hoc analysis was performed on the data from a 54 weeks phase III study (ClinicalTrials.gov identifier: NCT00923091) to measure changes in the health-related quality of life (HRQoL) of 2,690 patients aged ≥18 with moderate-to-severe hypertension who received one of six doses of olmesartan/amlodipine/hydrochlorothiazide (OLM/AML/HCTZ), using the MINICHAL and EQ-5D instruments. METHODS: Descriptive statistics were used to assess blood pressure and HRQoL scores over the study period. Analysis of covariance (ANCOVA) was used to identify those factors that could possibly have influenced HRQoL. Linear regression was used to assess the relationship between changes in blood pressure and HRQoL scores. RESULTS: Patients' baseline MINICHAL mood and somatic domains scores were 5.5 and 2.6. Over the study period HRQoL improved as both MINICHAL scores decreased by 31-33%. Patients' baseline EQ-5D index and VAS scores were 0.9 and 73.4 respectively, increasing by 6% and 12% over the study period. Patients' QALY gain over the 54 weeks study period was estimated to be 0.029 QALYs. The ANCOVA showed that changes in patients' HRQoL was likely to have been influenced by patients' achievement of blood pressure control, the amount of concomitant medication and patients' last used dosage strength of antihypertensive. Linear regression showed that blood pressure improvement may have been associated with improved HRQoL. CONCLUSIONS: This study showed that OLM/AML/HCTZ reduced blood pressure and significantly increased blood pressure control whilst improving patients' HRQoL. Achieving blood pressure control, amount of concomitant medication and dosage strength of antihypertensive impacted on patients' HRQoL.

Triple Regimen with Rituximab, Plasmapheresis and Intravenous Immunoglobulin in the Treatment of Dialysis Dependent Acute Humoral-Mediated Rejection in Kidney Grafts

Introduction: The clinical importance of humoral-mediated acute rejection has been progressively recognised. Early recognition and treatment with plasmapheresis and intravenous immunoglobulin have recently improved short term prognosis. Case report: In this report we describe the clinical features of three 2nd transplant patients developing severe acute humoral rejection during the first week post-transplant while on anti-thymocyte globulin therapy. Treatment with plasmapheresis/ intravenous immunoglobulin/rituximab resulted in rapid reversal of oliguria,and recovery of renal function within the 1st week of treatment in 2/3 patients. Diagnosis was confirmed by graft biopsies revealing peritubular neutrophiles and C4d deposits. Sequential graft biopsies in all three patients revealed complete histological recovery within two weeks. One patient never recovered renal function, and one patient lost his graft at three months following hemorrhagic shock. After 2 years follow up, the remaining patient maintains a serum creatinine of 1.1mg/dl. Conclusion: The regimen using plasmapheresis plus intravenous immunoglobulin and rituximab was effective in rapidly reversing severe acute humoral rejection.

Produção e facilitação da visualização on-line de uma carta de desporto de natureza

Os Sistemas de Informação Geográfica detêm um papel de crescente importância para a tomada de decisão ao nível do ordenamento do território, conforme o que a própria legislação evidencia. Existe uma carência de uniformização da informação para que possa existir um cruzamento eficiente e uma disponibilização mais facilitada à população e às diversas entidades. As instituições públicas, como é o caso do Instituto de Conservação e Florestas (ICNF I.P.), reconhecem esta necessidade, pelo que se propôs uma série de tarefas, para a concretização deste estágio, no sentido de a colmatar. Este instituto detém um papel de especial relevo na conservação do património natural assim como no ordenamento das áreas protegidas para que se possa usufruir das mesmas, sob um ponto de vista cada vez mais ecológico e promotor de desenvolvimento sustentável. A elaboração de um instrumento de gestão territorial, como se pode classificar a Carta de Desporto de Natureza (CDN), acarreta grande responsabilidade e exige um forte empenho, não apenas no envolvimento da população e das entidades que dele fruirão, mas no cumprimento da legislação existente quer para as atividades quer para o próprio território, no sentido da sua proteção, preservação e promoção de usos adequados. Neste trabalho procurou-se cumprir todas estas disposições sempre com o objetivo de, ao se construir normas de uniformização e ao se elaborar um exemplo de CDN para um território com tanto valor como é a Reserva Natural do Estuário do Tejo, tornar acessível a informação sobre esta área protegida. A intensão é também promover a motivação para a prática de um desporto natureza, saudável e em equilíbrio com o ambiente. O desafio não se ficou por aqui, havendo também a procura de utilização de Free Open Source Software, para que o processo de utilização e disponibilização informação SIG seja cada vez mais acessível e direta.

SMEs engaging at the bottom of the pyramid: Exploring drivers of business strategies

This research paper investigates how the market conditions at the base of the pyramid (BOP) influences South African small and medium sized enterprises (SMEs) to take certain business decisions in the townships and rural areas. It takes a qualitative approach to explore how SMEs with social objectives develops mitigating strategies to successfully engage with and in poor communities. The research suggests that prevailing BOP strategies are lacking certain aspects to successfully realize them on the ground. It advices firms to take a more practical hands-on approach to identify a sustainable business model by testing, experimenting, learning and adjusting, eventually being eligible for up-scaling.
