In recent years, both in the Republic and in the CIS and far abroad are developing low-intensity stationary systems of irrigation, consisting of Micro Sprinklers, impulsive actions, aerosol auto oscillatory action sprinkling irrigation, auto oscillatory action auto oscillatory action combined, the drip, drip pulsing and a number of others. This is because low irrigation system has a number of significant advantages over other methods of irrigation. Especially promising the creation of automated sprinkling systems impulse machines, combined, auto oscillatory action stepper auto oscillatory action rocker type, pulse-airborne apparatus auto oscillatory action, etc.

The Researchers proved that the process of soil erosion is also closely linked to climatic conditions of the region. Therefore, depending on the climatic conditions of the erosive processes are different in both forms of its manifestation, and the quantitative indicators of development. For example, in the north-eastern part of the Greater Caucasus Highlands powerful deposition of snow cover, high intensity of spring melting of snow and summer rain water rainfalls the calling intensive lavages and size of its development areas. But here, against a backdrop of high air temperatures during the growing season, pronounced wind regime and extremely low relative humidity of the air is wind erosion. Climate also affects the surface configuration. Humid areas where vegetation cover protects the soil from severe manifestations of water and wind erosion, characterized by soft, rounded slopes.

In this study, a method of water leakage detection system was investigated using acoustic emission device, AQUA M 300D. It is used to pinpoint leakage sources for underground pipelines system. The leakage is detected by analyzing the feedback frequency, where leakage area produces higher frequency due to the vibration resulting from a high-pressure liquid that flows through the crevice. The method is successful to detect underground pipelines system leakage with 90% accuracy.

Lupine Publishers-Soil Science Open Access Journals



Before the advent of modern industry, nature had tangible additions in the composition of atmospheric water vapor natural evaporation from transpiration of plant and natural emissions, in particular, from the respiration of creatures, animal worlds. Every living being, every plant in its secretions, at the molecular level, in its secretions creates information about itself. It is known that in the exhalation of a living being in the moisture of breathing, in any secretions, information is contained. It is proved by the fact that animals determine their victims and the opposite sex by smells. Plants allocate their personal phytoncides.

A Mechanics-Based Procedure for Predicting Groundwater-Rise-Induced Slope Displacements: (OAJESS)- Lupine Publishers


A procedure for predicting cumulative slope displacements induced by groundwater table changes is proposed. The proposed procedure incorporates a back-calculation technique for the soil strength parameter based on the records of slope displacement and ground water table changes. The analytical tool for the back-calculation is a limit-equilibrium-based finite displacement method (FFDM) requiring force and moment equilibrium, displacement compatibility, and a hyperbolic shear stress-displacement constitutive law. The analyzed potential sliding mass is a statically determinate system, providing a closed-form solution for the displacement of the slope. Two well documented case histories of periodic rainfall-induced slope displacements are used to validate the proposed analytical procedures. The hyperbolic soil strength parameters back-calculated from the first event of slope displacement can be used as operational soil strength parameters for predicting subsequent slope displacements caused by rainfall-induced groundwater table elevation changes. The proposed method alleviates possible difficulties associated with the evaluation of soil strength using undisturbed soil sampling of colluviums in foothill areas. The proposed method requires little computer time in deriving useful information of slope displacement which cannot be achieved using conventional limit equilibrium methods or advanced numerical analyses. The proposed analytical procedure is valid only for simulating instantaneous sliding where time-dependent viscous (or creep) deformation is not dominant.

Evaluation of Host Associated Genetic Markers for Rapid PCR Based Identification of Fecal Contamination Sources in Water: (OAJESS)-Lupine Publishers


The water quality of many waterways in the state of Alabama, and in the nation as a whole, is deteriorating due to point and nonpoint source pollution from human and animal waste. Accurate identification of contamination sources is essential if we are to develop cost-effective pollution control strategies. The direct detection of host specific genetic markers by Polymerase Chain Reactions (PCR) has been widely used in identifying sources of fecal contamination in environmental waters. In this study, we conducted experiments to validate genetic markers associated with deer/elk, Canada goose, dog, and cattle for Microbial Source Tracking (MST) in Alabama. End point PCR was performed on 10 raw sewage samples and 133 fecal samples from nine animal species. Our results showed that CowM3, GFD (goose), and deer/elk associated markers have acceptable specificity and sensitivity, making them suitable for MST studies. However, the dog marker and one of the cattle markers (CowM2) exhibited cross reactions with other fecal samples. The performance of these host associated markers in environmental water was evaluated using both end point and quantitative PCR (qPCR). Human, goose, and dog markers were detected in several water samples by end point PCR; the human marker and CowM2 marker were also detected by qPCR. Samples collected after a significant rainfall event showed the highest frequency of genetic marker detection. Both human and Canada geese contributed to fecal pollution in samples from Parkerson Mill Creek.
