This study was conducted to investigate the relationship between food balance and diabetes mellitus, using published data on food balances in the Kingdom of Saudi Arabia during 2005-2007, published by the Ministry of Agriculture in 2012 and Medical Technical papers and Scientific Reports published on Diabetes Mellitus in Saudi Arabia in an explanatory study. Food balance was calculated per capita and then its level of change was compared with changing of diabetes mellitus in the country. Results illustrated that Saudi citizen daily protein consumption （DPC） during 2005-2007 （g/capita/day） is higher than the average global consumption level of protein with 15.27%, daily fat consumption （DFC） with 24.56% and daily energy consumption （DEC） with 16.93% and increases than recommended level by International Nutrition Organizations （INO） with 56% for protein, 60.49% for fat and 27.37% for energy. On the other hand, DPC per capita in Saudi Arabia decreased during the period 2008-2010 from 88.3 g/day to 82.36 g/day. Moreover, DFC per capita in Saudi Arabia decreased during the period 2008-2010 from 3,247.90 Cal/capita/day to 3,176.43 Cal/capita/day, and daily energy consumption （DEC） of Saudi citizen increases than world consumption with 16.93%, while increases with 27.37% than INO. Despite this, DPC, DFC and DEC per capita in Saudi Arabia were still higher than world mean. On the other side, results illustrated that the number of diabetic patients in Saudi Arabia during the same period （2005-2010）. The curve of diabetic patient＇s number in Saudi Arabia during 2005-2010 is regular ascending with increasing level ranged between 7.10% in 2005 and 12.44% in 2010. It is essential to devise Saudi National Programme to educate the public about the relation of food balances and diabetes, so it could be avoided, and provide citizens with healthy dietary balances tables.展开更多

The lack of experimental verification of performance is not conducive to voltage/var management or full utilization of device capaci- ties. In order to solve the above problems, the compensation device performance test was performed. The test items and procedures were selected based on related national standards with the consideration for different grid structures and wind farm operation modes. The testing contents included dynamic regulating range, active power loss, dynamic response time, and harmonic voltage level. Three types of compensation devices installed in different wind farms, namely SVG, TCR and MCR, were chosen and tested. The performances were compared and analyzed according to the field test results.展开更多
