Ibuprofen is one of the most widely used drugs in the world, which affects the health of living organisms by causing pollution in water sources. Therefore, this study was conducted with the aim of determining the effectiveness of modified carbon of straw and sesame stubble in removing ibuprofen from aqueous solutions. For this purpose, ammonium chloride, zinc chloride, and phosphoric acid were used to optimize the adsorbent. Also, the changes in the absorbent surface and its characteristics were studied using a scanning electron microscope (SEM) and infrared spectroscopy (FTIR) technique. After determining the optimal conditions of pH variables, contact time, temperature, and adsorbent dose, the surface adsorption process was investigated under three Langmuir, Freundlich, and Dubinin-Radoshkevich models. On the other hand, first-order and pseudo-second-order kinetic models were used to process the adsorption data. The results showed that the surface adsorption process followed the Freundlich isotherm model pseudo-second-order kinetics. pH, contact time, initial concentration of ibuprofen, and optimal adsorbent dose were 3, 120 min, 50 mg/l, and 0.10 g/l respectively at 25°C. The results of this study showed that agricultural residues such as straw and sesame stubble can be used as effective and cost-effective adsorbents to remove the remaining pharmaceutical compounds from aqueous solutions.

One of the most important health indicators is the death rates. In fact, death data by age and sex are the main inputs to measure the health status of the community and with other epidemiological information, they are stone of economic and social decision making. Aim of this study was to investigate the causes and the 5-year trend of mortality from 2007 to 2011.
This study is a cross-sectional study that was conducted on the death death of Ilam province by urban and rural areas from 2007 to 2011. Is done, the data collected by the costructed form.
Findings: The results of this study showed that The mortality rate respectively in urban and rural areas of Ilam province in 2007 years, 3.3 and 5.2 and about 4.6 and 3.6 per thousand was reported in 2011 years, The mortality rate of women during these years from 3.1 to 3.6 and from 4.8 to 4.9 in the men reached. The highest number of deaths in urban and rural areas in the age group 70 years and older. In all the years of study in cardiovascular disease is the largest cause of death.
The results of this study showed that respectively, in urban and rural areas, 43/9 percent and 36 percent in year 2011, 52/9 and 39/1 percent percent is caused by cardiovascular diseases. During the study period 86 to 90, trend of mortality due to: cardiovascular diseases increased, cancers decreased, accidents have decreased somewhat fluctuating but overall, somewhat lower suicide; reduce aging and other cases were almost constant. Given that the incidence of this disease is largely dependent on life style, It seems planning to improve lifestyles through education and laws and regulations on risk factors such as smoking, lack of exercise, diet, stress, and sonon provide basis for reducing these diseases.
