The Role of Student and School Variables in Reading Performance among Those Participated in PIRLS 2006 M. S. Reza'ee A.R. Kiamanesh, Ph.D. Z. Naghsh, Ph.D. To determine the role of student and school variables in reading performance, the data on Iranian fourth graders who participated in PIRLS 2006 were analyzed. The sample had included 3978 students from 208 schools. At the stu...

Lithium ion batteries are among the most used rechargeable batteries in the world. Carbon nanostructures including carbon nanotubes (CNTs) are considered as important electrode materials for this kind of batteries. Therefore improving the performance of these carbon based electrodes in Lithium ion batteries is an important issue and attracts much attention in the battery community. In this manu...

In Wireless Rechargeable Sensor Networks, one or more special mobile entities (called the Mobile Chargers) traverse the network and wirelessly replenish the energy of sensor nodes, using wireless power transfer technology. In this paper, we present some state of the art algorithms that apply to characteristic problems in such networks, namely efficient use of wireless power transfer using i) on...

India has entered in the field of spent fuel reprocessing as early as sixties by way of R&D studies and finalising the process flow sheet. India's first spent fuel reprocessing plant was commissioned in the year 1965 at Trombay to reprocess spent fuel arising from research reactors. The recovered plutonium is being utilised to feed various programmes of the department. With the passage of time,...

The goal of this project is to predict how much time a physician should be spending with a patient, given the patient’s injury, referral status, and other reported, nonidentifiable medical information. This may be used as an additional factor for measuring and predicting physician efficiency alongside existing methodology. We implement linear regression and a variety of classification technique...

The disposal of spent refiactory materials has become a major problem for metals producers. The main issue surrounding refractory disposal is the elimination of the hazardous components of refractories, most commonly chrome-bearing materials and fluoride and cyanide in spent pot-liners. The various approaches to pollution prevention involve re-design to eliminate or significant reduction in was...

Introduction Rechargeable batteries are present in a variety of devices. The act of recharging them generally involves a charger wired to a wall outlet being plugged into the device. The charger can determine the type of charge the batteries receive and therefore determine the cycle life of the batteries. Wireless power transfer is on the cutting edge of the battery charging world. There are el...

background: the interaction between serum neuron-specific enolase (nse), biogenic amino-acids and neurobehavioral function with blood lead levels in workers exposed to lead form lead-acid battery manufacturing process was not studied. objective: to evaluate serum nse and biogenic amino-acids (dopamine and serotonin) levels, and neurobehavioral performance among workers exposed to lead from lead...

in this paper we present our studies using pauling electrostatic bond strength (esb) rules forstructural behaviour, cation vacancies, relation between x, y, and the valence of cations and coordinationin spinel compounds lixmn2o4, 0

background: hematological effects and digestive and neuro-psychological signs and symptoms are some manifestations of lead toxicity. however, there are conflicting reports of their prevalence among lead exposed workers and their relationship with blood lead levels (bll). this case- control study assessed the relationship between bll and hematological indexes and digestive (abdominal colic, iron...
