This research studies the application of a specific nanoemulsion as anti-Escherichia coli agent. The mixture was generated by simplex-centroid design. Physicochemical parameters such droplet average diameter, pH, viscosity, density, turbidity, whitening index, refractive stability (thermal, physical, and osmotic stability), antibacterial activity kinetic, have been assessed. nanoemulsions had d...

To reduce the environmental impacts and costs of production biolubricant, this work proposes use vegetable oil mixtures that have not been chemically modified. Formulations biolubricants were proposed with jatropha curcas, castor, macauba kernel, pulp oils since these potential physical-chemical properties to generate a high-performance biolubricant. A simplex centroid quaternary mixture design...

BACKGROUND AND AIMS Current agricultural practices are based on growing monocultures or binary mixtures over large areas, with a resultant impoverishing effect on biodiversity at several trophic levels. The effects of increasing the biodiversity of a sward mixture on dry matter yield and unsown species invasion were studied. METHODS A field experiment involving four grassland species [two gra...

Aim : This study was aimed to formulate a transdermal matrix patch using green tea leaf extract. Materials and methods The formulation optimized by the simplex lattice design method. correlation between responses analyzed chemometrics. observed were: 1. physical properties of patch, 2. percentage dissolution efficiency catechins, caffeine, epigallocatechin gallate released from patch. determina...

This experiment was carried out to study the effect of humic acid and growth promoting bacteria on uptake of cadmium heavy metal by annual alfalfa (Medicago scutellata L.). The experiment was arranged in pot experiment conditions in Isfahan, Iran in 2011. A factorial design was used based on completely randomized block design with four replications. Experimental treatments were humic acid and g...

tuberose (polianthes tuberosa l.) is one of the most important cut flowers in iran. this research was conducted to investigate the effects of spraying a mixture of amino acids on the physiological and morphological characteristics of tuberose. the experiment was carried out in two successive years (2009 and 2010) using two tuberose cultivars ‘dezfuli’ and ‘mahallati’. the experiment was arrange...

three hundred and sixty broiler chicks (ross 308) were employed in an experiment from 6 to 49 days of age to evaluate the effect of replacing canola meal for soybean meal either with or without enzyme supplementation. dietary treatments included 5 substitution levels (0, 25, 50, 75 and 100%) at two enzyme concentrations of: 0 and 400 g/ton in a 5×2 factorial layout experiment. the enzyme mixtur...

This paper presents the results of a parasitological study on internal parasitic infections in saposhnikovi shad, Alosa saposchnikowii, from the southern part of the Caspian Sea. In this regard 30 fish were studied for abdominal cavity parasites in February 2014. Results showed all of the specimens were infected at least with one kind of parasite and there was no significant difference in paras...
