1. Desenvolvimento de protótipo de coletor automático destinado à coleta de amostras de água em corpos aquáticos para análise em laboratório
O objetivo deste estudo é desenvolver e apresentar um protótipo de coletor automático de amostras de água. Nos últimos anos, tem havido uma crescente necessidade no uso de equipamentos automáticos no monitoramento de variáveis hidro-climáticas, tanto em ambientes rurais como urbanos. Esses equipamentos são normalmente usados para gerar informação

2. A new rapid method for automatic complement-fixation tests
Several automatic methods have been described for complement-fixation tests. However, each of these methods presents some inconvenience either due to cross contamination or to limited sensitivity. The new method consists basically in separating clearly the fixation stage from the haemolytic stage by using two different sampler plates placed on the same sampl

3. Microtiter assay for interferon: microspectrophotometric quantitation of cytopathic effect.
This report describes an accurate, reproducible, and efficient microassay for human interferon, using a dye-uptake method to quantitate cytopathogenicity. The antiviral activity was measured by using a Gilford 300-N microsepctrophotometer, with the automatic programmer, sampler, and data lister. Two hundred interferon samples, each in a final volume of 1.0 m

4. An evaluation of the Fisher Hem-Alyzer
The Fisher Hem-Alyzer is a multitest sequential discrete analyser with automatic printout of digitized results on paper tape. The instrument is well designed, soundly constructed, and reliable in routine use. Cross contamination from the sampler probe or between the cuvettes is minimal. Accuracy and precision are both highly satisfactory. Although the standa

5. Semiautomated Method for Microbiological Vitamin Assays
A semiautomated method for microbiological vitamin assays is described, which includes separate automated systems for the preparation of the cultures and for the measurement of turbidity. In the dilution and dosage unit based on the continuous-flow principle, vitamin samples were diluted to two different dose levels at a rate of 40 per hr, mixed with the ino

6. Analysis of lectin binding to glycolipid complexes using combinatorial glycoarrays
Glycolipids are major components of the plasma membrane, interacting with themselves, other lipids, and proteins to form an array of heterogeneous domains with diverse biological properties. Considerable effort has been focused on identifying protein binding partners for glycolipids and the glycan specificity for these interactions, largely achieved through
