Rivers can absorb certain amounts of contamination relying on different factors such as: river discharge, the primary conditions of the river, the river depth, discharge and the river viscosity of the offloaded wastes in the river. From parameters of water quality point of view, it is recom-mended to determine some parts of the river which are lower than the standard level in order to find out ...

[The] understanding which is relevant to the sciences of man is something more than this implicit grasp on things. It is related rather to the kind of understanding we invoke in personal relations when we say, for instance: ‘I find him hard to understand’; or at last I understand her’. To switch for a minute to another language, it is the kind of understanding one invokes in French when one say...

T esticular germ cells are clingy, adhering to the cells that nurture them. Huang and Stanley (1) reveal a protein whose activity promotes this togetherness by making glycoproteins on the germ cells’ surface stickier. Many proteins sport carbohydrate attachments called N-glycans (2). Cells affi x and modify N-glycans as a glycoprotein wends its way through the secretory pathway (3). How a prote...

Now, when, according to recent Web evolution trends, a human becomes a very dynamic and proactive player in a large highly heterogeneous and distributed environment with a huge amount of different kind of data, services, devices, etc., it is quite necessary to provide a technology and tools for easy and handy human information access and manipulation. Context-awareness and intelligence of user ...

This article examines general trends in teacher-reported conflict and closeness among 878 children from kindergarten through sixth grade, and examines early childhood characteristics that predict differences in initial levels and growth of conflict and closeness over time. Results indicated modest stability of teacher-perceived conflict and closeness through sixth grade, with relatively greater...

Karkheh river is located in southwestern of Iran. Industrial and agricultural activities around the river contaminate it through its path. Water quality modeling from upstream of Shoosh city to downstream was simulated by QUAL2K model. In this study, we investigated how best to manage the quality of Karkheh river to be done. Nine parameters including BOD, COD, DO, PH, turbidity, nitrate, phosph...

This study examined connections between pitch-class set-theoretical abstract concepts, set-classes, and perceptual estimations of chords derived from the set-classes. The study had two aims, the first of which was to compare theoretical resemblance with perceived closeness. Another aim was to illuminate and analyze both factors relevant for perceptual estimations of chords and factors relevant ...

Fluoride is one of the parameters which is non-degradable and naturally occurring inorganic anion found in many natural streams, lakes, and groundwater. Serious problems are faced in several parts of India due to the high consumption of fluoride through drinking water. These may cause dental and skeletal fluorosis to humans. This study aims to examine the level of fluoride in both Bharalu river...
