1. Assessment and incidence of fish associated bacterial pathogens at hatcheries of Azad Kashmir, Pakistan
Resumo O peixe é a fonte mais indispensável de proteínas para os indivíduos e tem alto valor nutricional. Por outro lado, a cultura dos peixes levantou questões sobre a saúde dos peixes devido ao próximo contato entre o ambiente aquático e os agentes patogênicos desses peixes. Assim, o objetivo do presente estudo foi identificar os patógenos bacter

2. MEASURING THE CONDUCTIVITY OF VERY DILUTE ELECTROLYTE SOLUTIONS, DROP BY DROP
Undergraduate experiments on ionic conductivity are common practice in general chemistry and advanced physical chemistry laboratories. Often, the conductivities are measured for solutions prepared for various salts, in a range of concentrations, and the relationship between solution conductivity and concentration is interpreted in terms of the Kohlrausch law

3. Efficiency of treatments for controlling Trichoderma spp during spawning in cultivation of lignicolous mushrooms
Trichoderma spp is the cause of the green mold disease in mushroom cultivation production. Many disinfection treatments are commonly applied to lignocellulose substrates to prevent contamination. Mushroom growers are usually worried about the contaminations that may occur after these treatments during handling or spawning. The aim of this paper is to estimat

4. Monitoramento temporal e espacial de contaminações bacterianas na produção de bioetanol: caracterização molecular por T-RFLP e detecção quantitativa por qPCRde comunidades formadoras de biofilmes / Temporal and spatial monitoring of bacterial contamination in bioethanol production: a molecular characterization by T-RFLP and quantitative detection by qPCR of community-formers biofilms
Bacterial contamination by Lactobacillus, Bacillus and Leuconostoc and other lactic acid bacteria is one of the main factors that affects the yield in alcoholic fermentation process. Biofilm formation protects the bacteria community and it is a permanent source of contamination. For characterization of these contaminations in (1) biofilms from centrifuge, ta

7. Determinação de resíduos dos pesticidas pirimetanil, pirimicarbe e buprofezina em águas ambientais por SPME e GCMS
The aim of the work was to develop method for determining pyrimethanil, pirimicarb and buprofezin residues in environmental water using solid-phase microextraction and gas chromatography-mass spectrometry. To perform the SPME, a 100 μm polydimethylsiloxane (PDMS) fiber was used for the extraction of the pesticides from water samples. Using univariate op
