Floods are one of the most destructive natural hazards in Pakistan, causing significant damage. During monsoons, when westerly winds and concentrated rainfall occur rivers’ catchments, floods become unmanageable. Given limited resources there has been minimal effort to quantify amount runoff generated by ungauged catchments. In this study, ten hill torrents Koh e Suleiman (District Rajanpur DG ...

Cellulose based polymers have shown tremendous potential as drug delivery carrier for oral drug delivery system (DDS). Hydroxyethyl cellulose (HEC) and hydroxypropyl cellulose (HPC) are widely explored as excipients to improve the solubility of poorly water soluble drugs and to improve self-life of dosage form. This work is an attempt to modulate the physicochemical properties of these cellulos...

Flash flood disaster ranks top among all the natural hazards across world due to its high frequency, severity and fatality. However, flash simulation is still challenging in small medium-sized catchments with complex orography, flashy hydrological responses poor observations. Three distributed models, i.e., TOPModel, HEC CNFF, are selected simulate floods seven humid six semi-humid China, consi...

For decades, performance has driven the high-end computing (HEC) community. However, as highlighted in recent exascale studies that chart a path from petascale to exascale computing, power consumption is fast becoming the major design constraint in HEC. Consequently, the HEC community needs to address this issue in future petascale and exascale computing systems. Current scientific benchmarks, ...

We have examined the effect of the virulent Leptospira interrogans strain Teramo, serotype icterohemorrhagiae, on the adherence of human neutrophilic polymorphonuclear leukocytes (PMN) to cultured human umbilical vein endothelial cells (HEC). Selective pretreatment of HEC with intact or sonicated leptospires caused a dose- and time-dependent increase of HEC-PMN adhesion (13.2% +/- 2.5% adherenc...

land use change is one of the main factors in the process of changing the regime of flood in watersheds. taleghan watershed has been subjected to many land use changes over years, which probably effects on flood characteristics of taleghan river. in present study the effects of land use change on some parameters including peak flow, volume and flood base time, in part of taleghan basin, was inv...

Hydroxyethyl cellulose (HEC) is used as a neutral excipient in microbicides used against sexually transmitted pathogens. However, HEC inhibits the infection of cervical epithelial cells by Chlamydia trachomatis at pH 5 in a concentration-dependent manner. At pH 7, infection is inversely dependent on the concentration of HEC, possibly due to pH-dependent calcium sequestration.

Bridges are crucial for transporting people and goods, but their failures can be catastrophic, resulting in loss of life property. This study assessed the flood stage selected bridges (Alaafin Avenue, Seven-Up, Oluyole) along Ona River, Ibadan, Nigeria, using a one-dimensional model called Hydraulic Engineering Center-River Analysis System (HEC-RAS). The requires two major input data: geometric...

Recent multimodel studies have shown that if one attempts to cancel increasing CO2 concentrations by reducing absorbed solar radiation, the hydrological cycle will weaken if global temperature is kept unchanged. Using a global climate model, we investigate the hydrological cycle response to “cirrus cloud thinning (CCT),” which is a proposed climate engineering technique that seeks to enhance ou...
