Aquagenic urticaria (AQ) is a rare physical urticaria induced by contact with water. It may be distinctive clinically, evident as 1-2 mm folliculopapular urticaria, a pattern also characteristic of cholinergic urticaria. AQ has a truncal and upper extremity distribution within 20-30 minutes after contact with water, regardless of its temperature or source. AQ is usually symptomatic with mild to...

this interdisciplinary paper aims at guangzhou’s development and its effects on surface andgroundwater quality taking the new city axis as an example. qualitative morphological analyses, field mappings, interviews and water sampling of standard in-situ and various hydrochemical parameters were conducted between 2007 and 2009 in order to examine the following research questions: which types of l...

the soil water retention curve (swrc) is a basic characteristic of the determination of soil hydraulic properties, including unsaturated hydraulic conductivity. measurement of this curve is essential to research, thus scientists have focused on indirect methods such as pedotransfer functions and empirical relationships to estimate swrc easily. since there is a close relationship between swrc an...

abstract climate change means a significant change in the long-term weather of a region in comparison with what has been observed during a long term period. precipitation and minimum and maximum temperature are three variables which are affected directly by the climate change. furthermore, the water yield of a river is one of the most important hydrological variables of a basin which is affecte...

Measuring sensitivity of hydraulic structures is considered as an approach for evaluation of water projects performance, due to lower distribution efficiency in Irrigation and Drainage project schemes. Sensitivity analysis approach for irrigation structures is one of flow analysis methods which are developed in recent years in order to measure the behavior of flow in hydraulic structures in an ...
