synopsis-in this research, possible usage of eaf dust on cement is investigated. therefore, effects of addition of different percentages of eaf dust on the most important properties of cement such as hydration heat, water coefficient, viscosity, initial and final setting times, strength development and leachability of heavy metals were studied. results showed that eaf dust alters the characteri...
in this work, the waste stone sludge obtained from the granite and marble stone processing factories was used for the manufacture of artificial stones using vibratory compaction in a vacuum environment. the results obtained showed that water absorption and density increased, and the flexure, compressive, and tensile strengths decreased with increase in the content of the waste stone sludge. the...
wastewater contains a variety of chemical substances owing to the different sources that contribute to affluent into sewage treatment plants. raw and wastewater samples were obtained from the surface of the water bodies at depths of 50 and 100 metres but at different locations in each sampling site. the water samples were subjected to extraction of polychlorinated biphenyls (pcbs) using quecher...
aims: sludge is an inescapable component of all wastewaters that originated from their treatment. dissolved air flotation (daf) process as an alternative clarifier is used in treatment of drinking water, pretreatment of wastewater, and as a phase separator in sludge activation processes. this study aimed to calibrated the usage of daf process in a laboratory scale and under various conditions, ...
the purpose of the present study was to investigate the effect of task-based instruction of vocabulary on the receptive and oral productive acquisition of english vocabulary and compare the results with those obtained from the traditional method. the method and procedure applied in this study was as follows: after the implementation of opt, a group of sixty female students were chosen. the stu...
the present study sought to examine whether a task-based approach could have an impact on raising awareness of collocations. moreover, it sought to investigate the facilitative role of consciousness-raising tasks of collocations in the communicative instances of use. to this end, 68 intermediate learners of english were selected via a placement test. the participants were taught with classroom ...
in this thesis, a structured hierarchical methodology based on petri nets is used to introduce a task model for a soccer goalkeeper robot. in real or robot soccer, goalkeeper is an important element which has a key role and challenging features in the game. goalkeeper aims at defending goal from scoring goals by opponent team, actually to prevent the goal from the opponent player’s attacks. thi...
Department of Environmental Engineering, Faculty of Civil Engineering, Universiti Teknologi Malaysia, 81310 UTM Skudai, Malaysia Corresponding Author: Johan Sohaili ___________________________________________________________________________ Abstract From the use of renewable resources and environmental protection viewpoints, recycling of waste printed circuit boards (PCBs) receives wide concern...
Sorting and recycling of endocytosed proteins are required for proper cellular function and growth. Internalized receptors either follow a fast constitutive recycling pathway, returning to the cell surface directly from the early endosomes, or a slow pathway that involves transport via perinuclear recycling endosomes. Slow recycling pathways are thought to play a key role in directing recycling...
The small GTPase rab6A but not the isoform rab6A' has previously been identified as a regulator of the COPI-independent recycling route that carries Golgi-resident proteins and certain toxins from the Golgi to the endoplasmic reticulum (ER). The isoform rab6A' has been implicated in Golgi-to-endosomal recycling. Because rab6A but not A', binds rabkinesin6, this motor protein is proposed to medi...
