ABSTRACT The issue of environmental protection has led researchers to pay serious attention to waste tires. Civil engineers have found that waste tires can increase bearing capacity, earth slope stability, and other useful applications in civil engineering. In this paper, a series of experimental modeling have been performed to investigate the effect of waste tires on increasing the stabi...
The issue of slope stability is one the most important and yet difficult geotechnical problems. Assessing particularly because many uncertainties involved in process. To take these into account, probabilistic methods are used, reliability approach adopted. There for assessment earth stability. However, there no system that would organize all an unambiguous way. In fact, can be classified differ...
The effects of lagomorph grazing on the Orthoptera a small hill in Mistley (southeast England) were studied during summer 2020. Transect counts revealed low sward height with abundant bare earth due to high wild rabbit Oryctolagus cuniculus slopes. This intensive led only field grasshopper Chorthippus brunneus (Thunberg, 1815) adults being found any number slopes, perhaps utilizing short swards...
two poly(oxyethylene) derivatives 1.10-bis(2'-benzoic acid)-1,4,7,1-tetradecane (l1) and 1,7-bis(2'-benzoic acid)-1,4,7-trioxaheptane (l2) were used as suitable ionophores for the preparation of potassium-selective pvc-membrane electrodes. the resulting electrodes based on l1 and l2 exhibit linear responses to the activity of k+ ions within the concentration ranges of 3.1´10-5 -2.7´10-2 m and 2...
Introduction The human need for energy is continually increasing and the limited sources of fossil energy are reducing. The indiscriminate use of fossil fuels pollute the environment and threaten life on the earth. Besides, because of difficult terrain, unfavourable topographical conditions and inaccessibility of some mountainous roads to national electricity network or high costs of these s...
Large ripples form striking patterns on the slopes of martian sand dunes which can be mapped and tracked using high-resolution optical images. The vary in orientation, wavelength, plan-view morphology, rates migration. variations ripple are recognized to signal effects regional local winds feedbacks between dune topography. We examine motion these interpret airflow dynamics around field at Nili...
Much uncertainty remains in measuring the inter-annual and longer-term dynamics of vegetation gross net primary productivity (GPP, NPP) connected land carbon sink. Potential for better GPP estimation lies newer satellite products representing different processes or states, but how they capture interannual to be explored. Here, we differentiate shorter- their drivers several Earth-observation-ba...
