In experiments on 11 normal subjects and on three dogs it has been observed that mercurial diuret-ics do not prevent the stimulation of water absorption and formation of hypertonic urine which characteristically follows the infusion of Pitressin. Furthermore mercurial diuretics only rarely increase urine flow when administered in the course of maximal water diuresis. These two facts are interpr...

While mapping algal blooms from space is now well-established, mapping undesirable algal blooms in eutrophicated coastal waters raises further challenge in detecting individual phytoplankton species. In this paper, an algorithm is developed and tested for detecting Phaeocystis globosa blooms in the Southern North Sea. For this purpose, we first measured the light absorption properties of two ph...

Chronic stress plays an important role in the development and exacerbation of symptoms in functional gastrointestinal disorders. To better understand the mechanisms underlying this relationship, we aimed to characterize changes in visceral and somatic nociception, colonic motility, anxiety-related behavior, and mucosal immune activation in rats exposed to 10 days of chronic psychological stress...

This paper presents the investigations conducted on three types of fibre-reinforced epoxy-resin hybrid composites with different structures, manufactured using midrib long fibres date palm (Phoenix dactylifera L.) and Calotropis procera fibres. The two were formed into flat sheets, without adding other chemicals or resins, employed as reinforcing layers in structure multi-layered laminate compo...

Improving winter wheat grain yield and water use efficiency (WUE) with minimum irrigation is very important for ensuring agricultural and ecological sustainability in the Northern China Plain (NCP). A three-year field experiment was conducted to determine how single irrigation can improve grain yield and WUE by manipulating the "sink-source" relationships. To achieve this, no-irrigation after s...

The Lake Warden wetland system (LWWS), on the south coast of Western Australia (WA), is a wetland of international importance for waterbirds. It occurs at the bottom of a heavily cleared agricultural catchment. Rising water levels associated with clearing have been identified as a threat to waterbird diversity. Different species of waterbird are typically found in specific ranges of water depth...

An efficient method for the determination of nanogram levels of zinc in waters (potable, irrigation, waste and sea waters) is described. Acidified water samples were analyzed by an accurately optimized time/temperature program for electrothermal atomic absorption spectrometry. The samples were previously treated with a matrix modifier consisting of 0.1% Mg(NO3)2 in 0.5 M HNO3 and injected throu...

The appraisal of the suitability some selected granite deposits for aggregate stone production within basement complex Mista Ali Jos Plateau state road construction was carried out. Aggregate samples obtained from were analyzed in laboratory to determine their mechanical properties by a series composite testing parameters using abrasion value (AAV), impact (AIV), crushing (ACV), specific gravit...
