a total number of 67 workers of teheran battery workshops were investigated for probable lead absorption due to the working with lead storage batteries. twenty workers with other occupations were selected as control group. blood and urine analysis were carried out for both groups. lead content of the urine in about 95.5% of the subjects was below 10 μg/100 ml. two subjects showed higher concent...

Output power in a hybrid power system is constant while the input power with variable characteristics that is generated by different sources. Using Hybrid Electrical Energy Storage (HEES) systems, is growing rapidly since there is an obvious need for clean energy. This paper introduces different parts of a HEES system and then proposes HEES systems which employ battery, ultracapacitor and f...

The Energy Storage System (ESS) is an expensive component of an E-bike. The idea of Hybrid Energy Storage System (HESS), a combination between battery and Ultra-Capacitor (UC), can moderate the cost of E-bike ESS. In this paper, a cost function is developed to use for optimal sizing of a HESS. This cost function is consisted of the HESS (battery, UC and DC/DC converter) cost and the cost of bat...

Theoretical explorations have revealed that quantum batteries can exploit correlations to achieve faster charging, thus promising exciting applications in future technologies. Using NMR architecture, here we experimentally investigate various aspects of with the help nuclear spin systems a star-topology configuration. We first carry out numerical analysis study how charging battery depends on r...

the satellite battery pack is one of the important and vital parts that are required for conducting special design with multiple capabilities. some parameters like the minimum weight, lack of outgassing of parts, avoiding from short- circuit in batteries inside battery pack, the possibility for making series connection in batteries, and prevention from destroying battery pack structure caused b...

objective: as domestic violence becomes increasingly recognized a widespread social problem, judicial system has begun playing larger roles in providing legal protection to these victims. one way they are doing this in the united states is through the use of protective restraining orders or injunctions. the purpose of this research was to determine if permanent injunctions for protection provid...

Among the power drills ( Electrical/ Pneumatic/Battery ) used in Orthopedic surgery, battery drill has got several advantages. Surgeons in low resource settings could not routinely use Orthopedic battery drills (OBD) due to the prohibitive cost of good drills or poor quality of other drills. “Hardware” or Engineering battery drill (HBD) is a viable alternative to OBD. HBD is easy to procure, ru...

the present study was designed to develop a preliminatory cognitive screeting test battery for differentiating brain damaged patients, from psychiatric patients and normal subjects.based on previous researches, the items scales, administraion and scoring instructions for the test battery were prepared. the test included the following scales: attention, memory, construction ability, receptive la...

This paper investigates the effect of temperature on a hybrid energy storage system with various energy management systems. The hybrid energy storage system consists of a fuel cell, ultracapacitor and battery with associated DC/DC and DC/AC converters. The energy management strategies employed are the state machine control strategy, fuzzy frequency/logic decoupling strategy, minimization strate...
