1. INTERACTIONS BETWEEN ADJUVANTS AND THE FUNGICIDE AZOXYSTROBIN+BENZOVINDIFLUPYR IN HYDRAULIC SPRAYING
ABSTRACT Adjuvants are tools to maximize pesticide spray quality. This study aimed to evaluate the interaction effects between adjuvants and the fungicide azoxystrobin + benzovindiflupyr on the physicochemical characteristics, droplet evaporation time, and spray droplet size. The experiment was carried out using a 2×6 factorial scheme, in which the first fa

2. EFFECT OF NOZZLES, APPLICATION RATES, AND ADJUVANTS ON SPRAY DEPOSITION IN WHEAT CROPS
ABSTRACT The use of insecticides is common in pest management in wheat crops but may lead to higher production costs and environmental contamination. Therefore, a more comprehensive and uniform distribution of plant protection products in the desired target is recommended. The objective of this study is to evaluate the effect of different spray nozzles, appl

3. Development and Characterization of Synthetic Chalcones-Loaded Eudragit RS 100 Microparticles for Oral Delivery
Eudragit® RS100 microspheres of two chalcones were prepared by solvent evaporation technique. A simple and rapid high-performance liquid chromatography (HPLC) method was developed and validated to determine the encapsulation efficiency, drug loading and release profiles of these chalcones in a microparticulate system. The mean EE values for the two chalcone

4. ADJUVANTS IN FUNGICIDE SPRAYING IN WHEAT AND SOYBEAN CROPS
ABSTRACT The objective of this study was to determine whether the combination of adjuvants to fungicides significantly alters the spray physicochemical characteristics, and potentiates the chemical control of foliar diseases, in that it may affect yield components in wheat (Triticum aestivum) and soybean (Glycine max). The experimental design was completely

5. Physical stability and clinical efficacy of Crocodylus niloticus oil lotion
ABSTRACT The stability and the anti-ageing, skin hydrating and anti-erythema effects of a commercialized Crocodylus niloticus Laurenti, 1768, Crocodylidae, oil lotion was determined. The lotion was stored at controlled conditions over six months during which several stability tests were performed. For the clinical efficacy studies lotion was applied on volar

6. Preparation of an Injectable Macroporous α-TCP Cement
Abstract One of the most important characteristics of calcium phosphate cements is their resorbability when implanted in the body. However, the in vivo resorption rate is slow due to the lack of intrinsic open porosity. In this study, macroporous structures were obtained by mixing alpha-tricalcium phosphate (α-TCP) cement with a foamed liquid phase containi

7. Characterization of biotechnologically relevant extracellular lipase produced by Aspergillus terreus NCFT 4269.10
Abstract Enzyme production by Aspergillus terreus NCFT 4269.10 was studied under liquid static surface and solid-state fermentation using mustard oil cake as a substrate. The maximum lipase biosynthesis was observed after incubation at 30 °C for 96 h. Among the domestic oils tested, the maximum lipase biosynthesis was achieved using palm oil. The crude lipa

8. Surface treated fly ash filled modified epoxy composites
Fly ash, an inorganic alumino silicate has been used as filler in epoxy matrix, but it reduces the mechanical properties due to its poor dispersion and interfacial bonding with the epoxy matrix. To improve its interfacial bonding with epoxy matrix, surface treatment of fly ash was done using surfactant sodium lauryl sulfate and silane coupling agent glycidox

9. Time-resolved fluorescence quenching studies of sodium lauryl ether sulfate micelles
Números de agregação (N Ag) de micelas do detergente aniônico lauril éter sulfato de sódio (SLES), com duas subunidades de óxido de etileno, foram determinados a 30 e 40º C por supressão de fluorescência resolvida no tempo, utilizando pireno como sonda fluorescente e o íon N-hexadecilpiridíneo como o supressor. O crescimento das micelas de SLES i

10. Effects of precursor on the morphology and size of ZrO2 nanoparticles, synthesized by sol-gel method in non-aqueous medium
Pure zirconium oxide (ZrO2) nanoparticles with diameters 10-25 nm were synthesized from ZrOCl2.8H2O and Zr(SO4)2.H2O with benzyl alcohol as non-aqueous solvent medium using sol-gel method. Sodium lauryl sulfate was added as surfactants to control the particle size. The synthesized ZrO2 nanoparticles have a mixture of tetragonal and monoclinic structure. The

11. Cefuroxime axetil loaded gastroretentive floating tabletsbased on hydrophilic polymers: preparation and in vitro evaluation
The aim of this work was to study the formulation and in vitro characterization of hydro dynamically balanced floating matrix tablets using Cefuroxime axetil (CA) as model drug. Different excipients such as hydroxy propyl methyl cellulose (HPMC) K15M, E5LV (gelling agent), sodium bicarbonate (gas generating agent) and sodium lauryl sulfate (SLS) (solubility

12. Evaluating the effect of soil flushing with surfactant on the biodegradation of soil contaminated by diesel oil. / Avaliação do efeito da lavagem com surfactante na biodegradação de um solo contaminado por óleo diesel.
Diesel fuel is one of the most petroleum derivates consumed in Brazil and responsible with large numbers of contaminated areas. While there are consecrated techniques for the removal of diesel oil-free phases, vapor and dissolved, the solutions to remove the residual phase still need greater efficiency and/or lower cost. This work shows the results of a labo
