The worldwide prevalence of overweight and obesity have increased drastically in recent years in both developed and developing countries, making obesity prevention an international public health priority.
Methods
A descriptive cross-sectional study aimed to determine the prevalence of overweight and obesity among students aged 13–17 years was carried out for the three month period starting from February 2011 in a southern rural Palestinian community, and to compare the prevalence by gender, age-group and family income.
Measurements
Anthropometric measurements and demographic data were taken from all students by the researcher. The body weight of the students in light clothes was measured to the nearest 0.1 kg using a digital scale calibrated daily. Height was measured to the nearest 1.0 cm using a metric measuring tape affixed on the wall. Students were weighed on a digital scale twice and the average was recorded.
Results
In a cross sectional study sample of 720 school students the prevalence of overweight (body mass index ≥ 85th percentile Ë‚ 95th percentile) and obesity (body mass index ≥ 95th percentile) was 27.8% (18.6% overweight and 9.2 % obese) and was significantly higher among male students, students with moderate income families and those aged 13 years old or younger.
Conclusion
This high prevalence of overweight and obesity is a serious concern for public health in Palestine. This health problem is rapidly increasing in developing countries including Palestine to alarming levels, which indicate an urgent need for effective intervention to deter or to curb this trend.
Ancient Potteries are among the oldest and most significant technological innovations in the history of human achievement, and were the first truly synthetic material. Spectroscopic techniques are very useful tools to achieve a detailed knowledge of the art works. In the present study thermogravimetry (TG) and differential thermal analysis was carried out for pottery samples recovered from the ancient settlements of kaveripakkam, Vellore Dist, Tamilnadu to estimate the firing temperature. The TG–DTG curves were obtained in the temperature range 0–1000°C. The results are discussed and the conclusion is drawn.
To interpret palaeoclimatology of Vestfold Hills region, an inland lake sediment core of 47 cm length was studied with respect to its diatom population. A total of 13 diatom species was identified and used for the Q-mode cluster analysis. Cluster analysis delineates five major clusters, including two sub-clusters. These clusters and sub-clusters are represented by typical diatom assemblages, arranged along the length of the core. Increasing trend of Diploneis crabro and decreasing trend of Fragilariopsis curta and Achnanthes taylorensis towards the top of the core reveals colder climatic condition during early to mid-Holocene which changed to warmer climatic condition and nutrient-rich lacustrine environment during late Holocene. It also implies the ice cover of the lake was melt not less than late Holocene. However, the continuous presence of marine diatom reveals that the lake was constantly in contact with the marine water inlet.
It is essential to provide an enabling environment (particularly temperature control) for premature born babies to minimize the neonatal deaths. Solar thermal energy can be utilized to keep neonates warm. This paper presents the design of solar thermal incubator system (viz., solar water heating unit and water-air heat exchanger) for accommodating five babies, which was successfully tested in a leading hospital in Mumbai, India.
Hybrid energy power system is built in many rural areas where the limited non-conventional energy sources are available due to higher transportation cost. Higher maintenance cost is one of the most reasons for diesel generators are very expensive for this area. This paper investigates cost and size optimization model for hybrid (solar, wind and diesel) power system demonstrate with Hybrid Optimization for Electric Renewable (HOMER) software. We present hybrid power system contain solar, wind and diesel power generation with battery storage for Jamnya Van village dist. Barwani in Madhya Pradesh, India. System designed based on site empirical weather and load data. We optimize a problem to minimize total net present cost, operating and running cost of the hybrid system.
Global atmospheric electrical parameters like as atmospheric conductivity, air-earth current density, electric field, and atmospheric potential have been estimated over 220 orographicaly important different places of China assuming fair weather conditions. Calculations have also been made for total cloud condensation nuclei for these places of China. Atmospheric electrical conductivity and current density have been found to increase with height from sea level, while electric field and atmospheric potential decrease in Chinese orography. New best fit regression lines along with various statistical parameters like as mean, median, average deviation, and different coefficients such as correlation, kurtosis, pearson and skewness have been obtained between the atmospheric electrical parameters and height from sea level for the orography of China in clean and clear atmosphere. The results show that the orographic feature is more important than the latitudinal behavior over China in the lower troposphere.
