A laboratory investigation of bed-load transport of gravel sediments under dam break flow

Dam break flows and resulting river bed erosion can have disastrous impacts on human safety, infrastructure, and environmental quality. However, there is a lack of research on the mobility of non-uniform sediment mixtures resulting from dam break flows and how these differ from uniform sized sediment. In this paper, laboratory flume experiments revealed that coarse and fine fractions in non-uniform sediment had a higher and a lower bed-load parameter, respectively, than uniform sediments of the same size. Thus, the finer fractions were more stable and the coarser fractions were more erodible in a nonuniform bed compared to a uniform-grained bed. These differences can be explained by the hiding and protrusion of these fractions, respectively. By investigating changes in mobility of the mixed-size fractions with reservoir water levels, the results revealed that at low water levels, when the coarser fractions were only just mobile, the bed-load parameter of the finer fractions was higher than the coarser fractions. The opposite was observed at a higher water level, when a significant proportion of the coarsest fractions was mobilized. The higher protrusion of these grains had an important effect on their mobility relative to the finer grains. The transported sediment on these mixed-sized beds was coarser than the initial bed sediment, and became coarser with an increase in reservoir water level.

Study of Physical, Chemical and Morphological Alterations of Smectite Clay upon Activation and Functionalization via the Acid Treatment

引用

World Journal of Nano Science and Engineering 2013年第4期3卷 161-168页

作者： mahmood Torabi Angaji amir Zamani Zinali Nader Taheri Qazvini School of Chemical Engineering College of Engineering University of Tehran Tehran Iran School of Chemistry College of Science University of Tehran Tehran Iran

The present study was carried out on the effect of acid leaching on the modification and structure alteration of montmorillonite. A nanostructured, activated material was prepared by selective leaching of pure smectite clay with different concentrations of sulfuric acid (1 - 10 N/L) at 85°C for 120 min using a solid/liquid ratio of 1:20 and a reflux system. The Fourier transform infrared (FTIR), scanning electron microscopy (SEM), transmission electron microscopy (TEM) and X-Ray diffraction (XRD) techniques were used for the characterization and study of the acid-treated montmorillonite clay. Chemical structure of specimens was distinguished by FTIR. The results showed that the formation of Si-OH bonds and leaching of Al3+ ions increased progressively with severity of the acid treatment. As the FTIR studies indicated, acid treatment led to the removal of the octahedral Al3+ cations and an increase in the Si-OH bonds. The morphological alteration of the untreated and treated montmorillonite was investigated by using TEM and SEM. X-ray fluorescence (XRF) analysis revealed a considerable decrease in the relative content of Al by increasing the acid strength. Moreover, the XRD results showed that the treatment using highly concentrated acid resulted in the formation of an amorphous silica phase.

Dielectric Properties of Multi-Layers Hexagonal Boron Nitride

引用

Materials Sciences and Applications 2020年第6期11卷 339-346页

作者： M. Fazail Khalid Ibtisam Riaz Rashid Jalil Usamah mahmood Rehan Rahat Mir Hafiz amir Sohail Department of Physics University of Engineering and Technology Lahore Pakistan Centre of Excellence in Solid State Physics University of the Punjab Lahore Pakistan

A higher value of the dielectric constant of h-BN makes it quite favourable material in energy storing device. The variation in dielectric constant was observed as a function of thickness. In this research work multilayers of Hexagonal Boron Nitride (h-BN) was fabricated by using the Chemical exfoliation method. Two solvents Dimethylformamide (DMF) and Isopropyl Alcohol (IPA) were used for the exfoliation of h-BN. Successful sonication of hexagonal boron nitride led to the formation of Boron Nitride nanosheets (BNNs). The stable dispersibility of h-BN in Dimethylformamide and Isopropyl Alcohol was confirmed by UV Visible Spectroscopy, X-ray diffraction (XRD) and Scanning electron microscopy (SEM) confirm the mono crystallite structure (002) and nanoflakes like morphology of h-BN respectively. This appropriate strategy offered a feasible route to produce multilayer of hexagonal boron nitride. After the successful fabrication of h-BN multilayers its dielectric properties were calculated by using LCR meter. Profilometer revealed the variation in thickness and value of Dielectric constant was calculated by using its formula.

Health 2012年第9期4卷 607-611页

作者： Khalid mahmood Hasan Salman Siddiqi Ashif Sajjad Sohail Shoukat Zahid Mehmood amir Wasim Alia B. Munshi Center for Environmental Studies PCSIR Labs Complex Karachi Pakistan Department of Chemistry University of Baluchistan Quetta Pakistan Department of Medicine Sandeman Provincial Hospital Quetta Pakistan Institute of Biochemistry University of Baluchistan Quetta Pakistan

Risk factors for iron deficiency anemia among the adult population of the Quetta valley have been investigated. Anemic adult patients, both males and females, who were admitted in the Sandeman Provincial Hospital, Quetta, were invited to participate in this study. After detailed history and examination, preliminary blood tests including full blood counts, platelets count, retics count, absolute blood values and blood film examination were done. A clinical diagnosis was made based upon the findings of history, examination and blood tests. In patients suspected to have iron deficiency anemia, serum iron studies (i.e. serum iron, Total iron binding capacity (TIBC) and serum ferritin) were done to confirm the diagnosis. Among the selected anemic patients, 60% were iron deficiency anemic, while 40% were non-iron deficiency anemic. Iron deficiency anemia was more common among females than males, as 70% patients were female and 30% were male. The risk factors were found to be pregnancy (40%), nutritional inadequacy (17%), menorrhagia (9%), hemorrhoids (9%), hook worms (8%), hematuria (2%) and blood loss due to various gastro-intestinal pathologies (15%).
