13. Sobrevivência e viabilidade de escleródios de Botrytis squamosa no solo
RESUMO Em experimento de campo quantificou-se a sobrevivência e a viabilidade de escleródios de Botrytis squamosa no solo. Cem escleródios multiplicados pela técnica de esfregaço de micélio em meio de cultura BDA foram colocados em saquinhos feito de tecido voal. Em armação de madeira contendo solo, colocaram-se 12 repetições respectivamente na sup

17. Evaluation of various soaking agents as a novel tool for heavy metal residues mitigation from spinach
Abstract Heavy metals pollution is a global threat to the environment and ecosystem due to various human and natural activities. Heavy metal intake through vegetables and diet leads to numerous ailments such as nervous disorder, kidney damage tubular growth and bone disease. The present study was conducted to mitigate the residue of heavy metals Hg, Pb, Zn

18. A Water Soluble Naphthalimide-Based Chemosensor for Fluorescent Detection CN- in Pure Water and Its Application in Practical Samples
By rationally introducing aromatic carboxyl functionalized 1,8-naphthalimide, a water soluble fluorescent chemosensor (DA) was successfully synthesized. It could selectively and sensitively detect CN- in pure water via an intramolecular charge transfer to twisted intramolecular charge transfer (ICT-TICT) state change mechanism. The detection limit of the che

19. Ion specificity in determining physico-chemical properties of drinking water
Abstract Drinking water plays a key role in regulating the daily salt intake, thus potentially affecting (either in positive or in negative direction) the incidence of diet-related pathologies, including nephrolithiasis. Being regarded as wholesome, bottled water is increasingly preferred to tap water. However, its physico-chemical characterization, as repo

20. A Novel Sensitive Bulk Optode Based on 5-Br Salophen as an Ionophore for Determination of Zinc Ion in Real Samples
An optical sensing film was fabricated for sensitive determination of zinc ion in aqueous solutions. The optical sensor was prepared by synthesized ionophore, 5-Br salophen, dioctyl sebacate (DOS) as a plasticizer, sodium tetraphenyl borate (NaTPB) as a lipophilic anionic additive in a poly(vinyl chloride) membrane. The optode response is based on the cation

21. Biocorrosion on Surface of ASTM A283 Carbon Steel, Exposed in Diesel S10 and Tap Water
This paper sets out to evaluate the corrosion and biocorrosion of carbon steel ASTM A283 exposed to a Diesel S10 oil/tap water system under static conditions for 90 days. The following analyzes were performed: physico-chemical in tap water, sulfur content in Diesel S10 and quantification of sessile microorganisms in the biofilm formed on the metal. To monito

22. STATISTICAL PROCESS CONTROL IN THE ASSESSMENT OF DRIP IRRIGATION USING WASTEWATER
ABSTRACT The aim of this study was to evaluate drip irrigation as a process, by monitoring the average flow applied by the emitter using tools of statistical quality control. Four kinds of drippers were selected, two inline labyrinth type and two online where one of the inline emitters was not self-compensating and the other, self-compensating emitter. The s

24. Development of Manual Shaking and Ultrasound-Assisted Surfactant-Enhanced Emulsification Microextraction for Analysis of Organophosphorus Pesticides in Aqueous Samples
A novel, rapid and efficient manual shaking and ultrasound-assisted surfactant-enhanced emulsification microextraction (M-UASEME) combined with gas chromatography-flame photometric detection (GC-FPD) was developed for the extraction and determination of eight organophosphorus pesticides (OPPs) in tap water and honey samples. The main parameters that affected
