PHYTOPLANKTON CHLOROPHYLL a ALONG SIX BIGHTS USED FOR MUSSEL CULTURE IN THE LITTORAL OF SANTA CATARINA.

A biomassa do fitoplâncton em seis enseadas do litoral catarinense utilizadas para o cultivo de moluscos marinhos foi avaliada por meio da clorofila a com a utilização da técnica de cromatografia líquida de alta eficiência (CLAE) ao longo de um ano. Os valores médios de Cla a foram relativamente baixos, variando entre 1,63 e 3,36 µg.l-1, com o máximo de 10,57 µg.l-1, observado na Praia Alegre, no município de Penha. O resultados indicam um grau geral de trofia moderado e similar para as enseadas estudadas.Phytoplankton biomass, as chlorophyll a was quantified along 6 bights used for mussel culture in the coastal area of Santa Catarina State. Chlorophyll a, determined by high performance liquid chromatography (HPLC), showed similar mean values among the sites, ranging from 1,63 to 3,36 µg.l-1, with a maximum for 10.57 µg.l-1 found in Praia Alegre, Penha, SC. The results indicates that all bight show a similar biomass and a moderate trophic grade

Direct Percutaneous Endoscopic Jejunostomy Using Single-Balloon Enteroscopy without Fluoroscopy: a Case Series

BACKGROUND: Direct percutaneous endoscopic jejunostomy (DPEJ) is a useful method to provide enteral nutrition to individuals when gastric feeding is not possible or contraindicated. The aim of this study was to analyze the efficacy and safety of DPEJ tube placement with the Gauderer-Ponsky technique by the pull method, using single-balloon enteroscopy (SBE) without fluoroscopy. METHODS: This is a retrospective analysis of patients undergoing SBE for DPEJ placement in a referral hospital between January 2010 and March 2016. Technical success, clinical success and procedure related complications were recorded. RESULTS: Twenty-three patients were included (17 males, median age 71 years, range 37-93 years). The most frequent indications for DPEJ were gastroesophageal cancer (n = 10) and neurological disease (n = 8). Eighty-seven percent of the patients had a contraindication to percutaneous endoscopic gastrostomy (PEG) and PEG was unsuccessful in the remaining patients. The technical success rate was 83% (19/23), transillumination was not possible in three patients and an accidental exteriorization of the bumper resulting in a jejunal perforation occurred in one patient. The clinical success was 100% (19/19). The median follow-up was five months (range 1-35 months). Apart from the case of jejunal perforation and the two cases of accidental exteriorization, there were no other complications during follow-up. The 6-month survival was 65.8% and the 1-year survival was 49.3%. CONCLUSION: DPEJ can be carried out successfully via SBE without fluoroscopy with a low rate of significant adverse events. Although, leaving the overtube in place during the bumper pulling can be useful for distal jejunal loops, it can be safely removed in proximal loops to minimize complications.info:eu-repo/semantics/publishedVersio

Requisitos preliminares para um sistema de apoio à decisão no planeamento da produção por encomenda

Um dos objectivos do escalonamento das ordens deprodução é garantir que as encomendas que as originamsejam concluídas o mais próximo possível da sua datade entrega. Os efeitos de uma situação de produçãoatrasada têm implicações a montante do sistema deprodução, enquanto que ordens de produção concluídasantecipadamente podem ser prejudiciais se o espaço dearmazenamento é uma limitação. A dificuldade doplaneamento e controlo da produção aumenta à medidaque as famílias de produtos aumentam e as suasquantidades diminuem.Este artigo identifica em primeiro lugar algumas dasdesvantagens existentes nos sistemas de planeamento econtrolo da produção tradicionais e apresenta aespecificação preliminar de um sistema de apoio àdecisão para o planeamento de produção num ambientemake-to-order. O sistema apresentado destina-se àindústria automóvel de componentes e tem comofinalidade principal apoiar o processo de planeamentode encomendas por forma a optimizar globalmente oprocesso de produção. Por outro lado, pretende-se queseja igualmente uma ferramenta de decisão que permitanão apenas determinar a data de conclusão daencomenda como também analisar o impacto de um reescalonamentoda produção assim como detectarestrangulamentos e avaliar o desempenho dos recursos

Quantification of humic acids in surface water: effects of divalent cations, pH, and filtration

Humic acids (HAs) content of raw water is an important analytical parameter in water treatment facilities because HAs in the presence of chlorine may lead to the formation of dangerous by-products (e.g., trihalomethanes). The concentration of HAs in water is not directly accessible by common analytical methods due to their heterogeneous chemical structure. The aim of this study was to compare two methods to assess humic acids (HAs) in surface water namely absorbance of ultraviolet light at 254 nm (UV254) and total organic carbon (TOC), as well as to evaluate the effects of calcium and magnesium concentrations, pH and sample filtration on the methods’ results. An aqueous solution of a commercial HA with 10 mg L1 was used in the present work. Quantification of the HA was carried out by both UV254 and TOC (combustion-infrared method) measurements. UV254 results were converted to TOC using a calibration curve. The effects of calcium (0–136.3 mg L1) and magnesium (0–34.5 mg L1) concentrations, pH (4.0, 7.0 and 9.0) and sample filtration on UV254 and TOC measurements of the HA suspension were evaluated. More accurate TOC values of HA suspensions were obtained by the combustion-infrared method than by the UV254 absorbance method. The higher differences of TOC values between unfiltered and filtered samples were detected in the presence of calcium at pH 9.0 using the spectrophotometric method.The work described in this paper was financially supported by FCT-Foundation for Science and Technology (Portugal)-by the PhD student grant SFRH/BD/18565/2004.
