The device has a sensor that periodically measures and records the ambient light level. Following retrieval of the device, the light level records are converted into latitudes and longitudes, which allows the geographic position of the animal to be estimated twice daily. The instrument is also configured to detect and record the history of time spent in water against time spent flying or on lan...

The periodic broadcasting of frequently requested data can reduce the workload of uplink channels and improve data access for users in a wireless network. Since mobile devices have limited energy capacities associated with their reliance on battery power, it is important to minimize the time and energy spent on accessing broadcast data. The indexing and scheduling of broadcast data play a key r...

The aim of this study was to determine the association of levels of physical activity (PA), physical fitness (PF), sedentary lifestyle and life satisfaction with the intention to be physically active after secondary school graduation, in teenagers of both genders. A total of 1986 Spanish adolescents (12-16 years) participated in this cross-sectional study. PA, sedentary lifestyle, life satisfac...

Lead citrate is a key precursor for the green recycling of spent lead acid battery paste in a citric acid/sodium citrate (CA/SC) solution. In this study, the main paste component, PbSO4, was leached and crystallized to yield lead citrate. Results showed that the leaching of PbSO4 in citric acid/sodium citrate solution was remarkably enhanced by an increase in temperature from 35 ◦C to 95 ◦C and...

Extreme response style (ERS) refers to the tendency to overuse the endpoints of Likert-type scales. This study examined the extent to which ERS is accounted for by measures of personality, specifically, intolerance of ambiguity, simplistic thinking, and decisiveness. One hundred and sixteen pairs of undergraduate students and one of their respective peers completed a battery of questionnaires a...

The open field and swimming maze tests are frequently used as part of a behavioural assessment battery in reproduction or developmental toxicology studies in the rat. Interpretation of the results of these tests is very difficult when the body weight of the rats is not similar in the various treatment groups. In order to better understand this problem, data from approximately 500 untreated rats...

Battery electric vehicles offer many advantages in terms of performance and zero-emission pollutants, but their limited range for long-distance trips compromises large-scale market penetration. The problem can be solved with a dense network fast-charging stations an increase embedded battery capacity. Simultaneously, improvements high-power charging point units gains hundreds kilometers mere 20...

A Wireless Sensor Network (WSN) is a collaboration of a large number of sensor nodes. The sensor node operates on small batteries with limited lifetime. Some sensors, acting as source nodes, transmit their sensed data to a sink node via multi-hop communication. Often nodes nearer to the sink expend more energy than the nodes farther from the sink. Therefore, it is highly desirable to have an ef...

Neuropsychological studies have consistently reported cognitive dysfunctions associated with multiple sclerosis. One-hundred fifteen subjects with relapsing-remitting multiple sclerosis (RRMS) were compared with forty health controls according to a neuropsychological test battery, which included digit span, trail making, cancellation and stroop test. Both groups were matched for age, sex and ed...

Batteries are omnipresent, and with the uprise of the electrical vehicles will their use will grow even more. However, the batteries can deliver their required power for a limited time span. They slowly degrade with every charge-discharge cycle. This degradation needs to be taken into account when considering the battery in long lasting applications. Some detailed battery models that describe t...
