this paper presents a method for generating a digital management map to apply cyanazine pre-emergence herbicide. the main objective was to develop a precision method to generate management maps for the variable rate application of herbicide to reduce the amount of herbicide applied and its adverse impact on the environment. first, local and utm coordinates of a field were determined using total...

This study aimed to model the habitat suitability for an invasive clam Corbicula fluminea in a coastal shallow lagoon in the southern Neotropical region (-30.22, -50.55). The lagoon (19km2, maximum deep 2.5m) was sampled with an Ekman dredge in an orthogonal matrix comprising 84 points. At each sampling point, were obtained environmental descriptors as depth, organic matter content (OMC), avera...

The research explores the possibilities of biogas extraction from aquaculture waste. Samples fish-farming pool sludge were taken a fish farm, which is located in Krāslava district, Kalnieši rural municipality. Prior to experimental fermentation and biogas, samples analyzed order determine their moisture organic matter content (OMC). For purpose increasing OMC available for fermentation, was mix...

abstract saturated water content is one of the important parameters which its measurement is necessary in estimation of soil water retention and unsaturated hydraulic conductivity curves. in several researches, saturated water content is assumed to be equal to soil total porosity. in some others, its value is estimated by pedotransfer functions using readily available parameters, such as bulk d...

Soil vapor extraction (SVE) and bioremediation (BR) are two of the most common soil remediation technologies. Their application is widespread; however, both present limitations, namely related to the efficiencies of SVE on organic soils and to the remediation times of some BR processes. This work aimed to study the combination of these two technologies in order to verify the achievement of the ...

Objective To determine and compare the SPF (Sun Protection Factor) and moisturizing effects of the liposomal and conventional lotion formulations containing octyl methoxycinnamte (OMC) as a sunscreen by in vivo methods. Materials and Methods The multilamellar liposomes (MLVs) containing OMC were prepared by fusion method and o/w emulsion was prepared as FDA standard sunscreen method. The SPF...

It is well known that soil fertility poor in most newly reclaimed land, which has been developed as an effective way to compensate farmland occupation. In order ameliorate the quality of this study investigated effect commercial organic fertilizer (COF) (0.45, 0.90, 1.35 and 1.80 kg/m2), sheep manure (SM) 0.75, 1.05 mushroom residue (MR) (1.50, 2.25, 3.00 3.75 chemical compound (CCF) (0.075 kg/...

The use of pesticides in modern agriculture is unavoidable because they are required to control weeds. Pesticides are poisonous; hence, they are dangerous if misused. Understanding the fate of pesticides will be useful to use them safely. Therefore, contaminations of water and soil resources could be avoided. The fates of pesticides in soils are influenced by their sorption, decomposition and m...

Recently most farmers in developing country like Nigeria has resulted to the use of solid wastes as compost replenish deteriorated soils while some are farming on abandoned waste dumpsite due their richness organic matter. This study assessed soil nutrient and fertility status by investigating influence (if any) physical chemical properties around Lapite for environmental sustainability. Ten sa...

This study examines the functional implications of postnatal changes in the expression of the mitochondrial transporter protein, 2-oxoglutarate-malate carrier (OMC). Online (13)C nuclear magnetic resonance ((13)C NMR) measurements of isotope kinetics in hearts from neonate (3-4 days) and adult rabbits provided tricarboxylic acid cycle flux rates and flux rates through OMC. Neonate and adult hea...
