Over-parameterization is a well-known and often described problem in hydrological models, especially in distributed models. Therefore, using special methods to reduce the number of parameters via sensitivity analysis is important to achieve efficiency. This paper describes a sensitivity analysis strategy that graphically assigns for each parameter a relative sensitivity index and relationship o...
one of the most commonly used techniques to reduce the corrosion rate of rebar in concrete is addition substances named corrosion inhibitors into the concrete. corrosion inhibitor is chemical compounds that were added to concrete to prevent corrosion of steel in concrete. sodium nitrate is a type of anodic inhibitors that this study investigatesthe effect of this inhibitor on the properties of ...
This paper describes the planning, design and construction of a permeable pavement as a practical demonstration of the benefits of eco-paving in Australian environmental management. The paper addresses the use of permeable pavements as part of a Water Sensitive Urban Design that allows infiltration of stormwater, reduction of pollutants and slow reticulation of the stormwater to an ecologically...
loss of arable land and irrigation water quality was evident in many parts of the country in recent years, and certainly this non-living stress will be one of the main challenges various crop will be confronted. soil and water salinities’ effects on agricultural production can be studied from different aspects. physiological disturbances in nutrients’ absorption are one of the main disadvantage...
gol-e-gohar iron ore mine of sirjan in southern part of iran is a large open pit that operates below the groundwater table and during mining operation, dewatering is required to prevent operation processes from flooding. current operation is going on by digging wells in or out of the pit and pumping to prevent flooding. as a result of the former dewatering operation a vast deep cone of depressi...
rivers and runoff have always been of interest to human beings. in order to make use of the proper water resources, human societies, industrial and agricultural centers, etc. have usually been established near rivers. as the time goes on, these societies developed, and therefore water resources were extracted more and more. consequently, conditions of water quality of the rivers experienced rap...
a novel, simple, sensitive and effective method has been developed for preconcentration of hg(ii) on nano-fe3o4-dop-ed solid-phase extraction adsorbent. in this paper, dioctyl phthalate (dop) was used to encapsulate nano-fe3o4 and produce a nano-fe3o4-dop sorbent based new sorbent was prepared. this was treated with ethylenediamine (ed) in another solvent-free procedure for the formation of a n...
Conjectural search queries (is python case sensitive, is millennium stadium heated) embody attempts by Web users to verify whether a particular property (soluble in water?, case sensitive?, heated?) does or does not apply to a particular instance (iodine, python, millennium stadium). This paper considers such queries to be a data source of attributes of open-domain classes. Conjectural attribut...
Background & Aim: The purpose of present study was to examine and validate the folk's claim of inhalation of Monechma ciliatum seeds powder by traditional African natives for cold and allergic conditions, so as to formulate a useful therapeutic agent to respiratory tract infections. Experimental: Different extracts were bio-assayed in vitro for their bioactivity to inhibit th...
In this paper, CN-DPA was prepared as an effective colorimetric and fluorescent probe for copper ions (Cu(2+)) in aqueous solution. It exhibits good sensitivity and selectivity for Cu(2+) over other metal ions both in aqueous solution and on a simple colorimetric paper-made test kit. Upon addition of Cu(2+), a remarkable color change from purple to colorless was easily observed by the naked eye...
