Prototype and methodology for the characterization of the polymer-calibrator in...

The extrusion of technical thermoplastics profiles generally uses a dry calibration/cooling system, composed by one or several calibrators in series. One of the major difficulties to be faced when modelling this important stage is an adequate prescription of the heat transfer coefficient, hinterface, between the plastic profile surface and the cooling medium, which must include the effect of the interface conta...

THE ROLE OF TAX AGENTS IN TAXPAYERS’ TAX COMPLIANCE

This paper aims to analyze the role of tax agents in tax compliance. The works that analyze this phenomenon can be divided into two major groups. Firstly, those that examine the role of tax agents, from the perspective of taxpayers, which indicate that their perception of tax complexity is the great motive to use tax agents’ service. Secondly, studies which analyze the tax agents' attitude. A first subgroup ana...

Nephrogenic diabetes insipidus associated with tenofovir administration: report...

Tenofovirrenal toxicity, particularly when associated with other antiretrovirals, has been reported in the adult HIV-positive population. Reports in HIVpositive children are very rare. The authors report a paediatric case of nephrotoxicity associated with tenofovir and didanosine, emtricitabine and lopinavirritonavir coadministration. A 12-year-old girl with AIDS (clinical stage C) with a multidrug-resistant v...

CFD simulation and experimental measurement of gas holdup and liquid interstiti...

This paper documents experiments and CFD simulations of the hydrodynamics of our two-phase (water, air) laboratory internal loop airlift reactor (40 l). The experiments and simulations were aimed at obtaining global flow characteristics (gas holdup and liquid interstitial velocity in the riser and in the downcomer) in our particular airlift configurations. The experiments and simulations were done for three dif...

Single-laboratory validation of determination of acetaldehyde, ethyl acetate, m...

This work presents the determination of principal volatile compounds (acetaldehyde, ethyl acetate, methanol, 2-butanol, 1-propanol, 2-methyl- 1-propanol, 2-propen-1-ol, 1-butanol, 2-methyl-1-butanol and 3-methyl-1-butanol) in wine spirits, brandies and grape marc spirits by GC-FID. The method was evaluated in terms of suitability of chromatographic system, accuracy, precision, linearity and detection and quanti...

Crescimento e produção de gérbera fertirrigada com solução nutritiva

Este trabalho foi conduzido com o objetivo de avaliar as características de crescimento e produção de quatro cultivares de gérbera de vaso fertirrigadas com duas soluções nutritivas. O experimento foi realizado em casa-de-vegetação, durante o período de maio a julho de 2006, na UNESP-FCA em Botucatu-SP. O delineamento experimental foi de blocos casualizados e constituído em esquema fatorial 4x2, sendo 4 cultiva...

Mastite em pequenos ruminantes no Brasil

Este artigo objetivou revisar as informações recentes sobre mastite em pequenos ruminantes, abrangendo etiologia, epidemiologia, aspectos de controle e profilaxia. Houve a preocupação em reunir resultados de estudos desenvolvidos no Brasil, uma vez que a mastite tem a interferência de uma série de fatores, como fatores ambientais e outros decorrentes dos sistemas de manejo empregados, condições essas determinan...

Clinical presentation of leptospirosis: a retrospective study of 201 patients i...

INTRODUCTION: leptospirosis is a zoonosis of worldwide importance. The disease is endemic in Brazil. This study was conducted to describe the clinical and laboratory presentation of leptospirosis in a metropolitan city of Brazil. METHODS: this is a retrospective study including 201 consecutive patients with leptospirosis admitted to tertiary hospitals in Fortaleza, Brazil, between 1985 and 2006. All patients ha...

Specific recommendations for PROs and HRQoL assessment in allergic rhinitis and...

The GA(2)LEN taskforce on Patient-Reported Outcomes (PROs) and Health-Related Quality of Life (HRQoL) published in 2009 a position paper concerning PROS and HRQoL assessment in clinical trials on allergy. Because of the specificity of this topic in asthma and rhinitis, specific recommendations are needed. The aim of this position paper is to define PROs and their meaning in asthma and rhinitis research, explore...
