Activated carbons (AC) prepared from rice husk by KOH activation in inert atmosphere at 750 and 850 0C were modified with nitric acid. Activation at 850 0C resulted in better pore development and was confirmed by SEM, Boehm titration and BET. The modification by nitric acid could reduce the particle size while enhance the amount of hydroxyl and carbonyl groups on the surface of AC samples. Bath adsorption of benzene, toluene and m-xylene (BTX) as well as dynamic adsorption of m-xylene were measured in order to evaluate the performance of AC for removing volatile organic compounds (VOCs). The results showed that AC sample prepared at 850 oC (RH-850) exhibited the best benzene adsorption capacity of 11.62 mmol g-1 in bath adsorption and m-xylene adsorption capacity of 9.140 mmol g-1 in dynamic adsorption at 50 0C.

Construction and development of classifier that work with more accuracy and perform efficiently for large database is one of the key task of data mining techniques [l7] [18]. Secondly training dataset repeatedly produces massive amount of rules. It’s very tough to store, retrieve, prune, and sort a huge number of rules proficiently before applying to a classifier [1]. In such situation FP is the best choice but problem with this approach is that it generates redundant FP Tree. A Frequent pattern tree (FP-tree) is a type of prefix tree [3] that allows the detection of recurrent (frequent) item set exclusive of the candidate item set generation [14]. It is anticipated to recuperate the flaw of existing mining methods. FP –Trees pursues the divide and conquers tactic. In this paper we have adopt the same idea of author [17] to deal with large database. For this we have integrated a positive and negative rule mining concept with frequent pattern (FP) of classification. Our method performs well and produces unique rules without ambiguity

Chemistry of natural product has contributed significantly towards the improvement of modern medicine. Custard apple (Annona squamosa ) is a nutritional rich fruit and is largely valued for its taste. It is known to have some active ingredients which kills lung, colon, breast and pancreatic cancer cells. Therefore, consumption of this fruit is known to have aided in anti-cancer activities. The investigation is carried out to find the chemical composition, phytochemical analysis and evaluation of crust, pulp and the seed of custard apple. The chemical characteristics such as pH, titratable acidity, total sugar and lipids are also verified. The results revealed that seed, pulp and crust contains adequate amount of vitamin C, citric acid, carbohydrate, protein etc. The phytochemical analysis revealed that custard apple contains tannins, flavonoids, cardiac glycosides and steroids. Standard GC analysis of seed oils contain certain types of essential oils which are mainly aiding in anti-inflammatory, anti-cancer and anti-microbial properties. The antioxidant activity is evaluated using DPPH (2,2-diphenyl-1-picryl-hydrazyl-hydrate) assay. The presence of anthocyanins may also offer anti-cancer, anti-inflammatory and anti-viral benefits of custard apple.

The personal background factors that influenced the seniors’ health promoting lifestyle are gender, living status. Family relationship has a significantly positive correlation with health promoting lifestyle.. Conclusions: A health promoting lifestyle will help prevent diseases and promote health, and can improve the quality of life. From the results of this study, it can be seen that the relationship between the elderly and their families will affect the health promoting lifestyle. The older the elderly, the more they need to care about their family relationships. We need to pay more attention to the family relationships of illiterate elderly people, divorced or widowed elderly people and elderly people living alone. We need to encourage more male elderly people, elderly people living with spouse and elderly people living alone to implement health-promoting lifestyles.

Game-theoretic approach is common in supply chain management to analyze the effect of controllable factors on the decision parameters. This study examines a combination of a long-term contract and a penalty contract for multiple periods between a single supplier and a retailer. Demand is stochastic but uniformly distributed over the selling seasons of periods. Supplier’s capacity decision is required to be taken at the beginning of period before the retailer placing the order. The supply chain performance is observed by analyzing committed order quantity and the sole total profits of supplier and retailer.

Abrus precatorius Linn. (Fabaceae) is a climbing shrub widely distributed in most of the districts of the country in hedges and among bushes on open lands. The objective of this work is to evaluate and compare anthelmintic activity of ethanolic extract of red seeds of Abrus precatorius. Earth worms were used for anthelmintic activity. Albendazole was used as standard drug. Time required for paralysis and death of animals were noted for each sample.

Desertification is a phenomenon that happens in arid, semi arid and sub-humid areas. Iran is an arid and semi arid country and has two deserts: Lut desert and Kavir plain. Sistan plain is a part of Lut desert and has a very dry territory which impress by driest situation. In Sistan plain, desertification is considered as the main cause of soil lose and biomass decreasing and cause to a fragile environment. The MEDALUS1 model is one of the most important projects that were provided by European commission for desertification assessment. One of the advantages of this model is its high precision. More over particular weighing of layers and usage of geographic information system (GIS) in overlying of indices maps are the other superiorities of this model that increase subtlety and speed of evaluation and preparation of desertification map as well as reducing expert's mistakes. In this research, the MEDALUS methodology was used to assess desertification rate in GHORGHORI region of Sistan plain. In first step, main indices and parameters in desertification process identified. Then, two main indices according to local conditions were selected: wind and water erosions. In second step, considering the main indicators in wind and water erosions, every indicator was quantified according to its quality and was given a weighting based on MEDALUS methodology. In next step, the quality maps of wind and water erosions were prepared using geometric mean of indicators using ArcGIS software. Ultimately, the final desertification map was developed by integration of wind and water erosion quality maps using GIS. Results shows that wind erosion index with average value of 2.84 and water erosion index with average of 1.86 take the high and medium class of desertification. Among main indicators of indices, land use with average of 3.25, percent of plant crown cover with 3.16, dusty days indicator with 2.98 and wind erosion intensity with 2.93 have the highest effects. Water erosion intensity with average of 1.01 has the lowest effect on desertification process. Desertification intensity for studied area was 2.3 that show the critical class (C3).

The cactus plant (Beles) grows profusely in Ethiopia and has adapted perfectly to the arid zones of the country characterized by droughty conditions, erratic rainfall, and poor soils subject to erosion. Cactus can be used for several purposes like sources of food, feed, as wind break, fence for crop and soil conservation for the people of the area. Although it is an important fruit and forage plant, there is no clear cut information about its current status, utilization, income contribution and marketing constraints in Bale Zone, South Eastern Ethiopia. To this end, the objective of this research was to assess the Current status, utilization, income contribution and marketing constraints of Cactus pear (Opuntia spp.) in selected districts of Bale Zone. In this study, three districts, namely, Sinana, Agarfa and Gasera were purposively selected based on their potential in cactus production and utilization. In addition, two kebeles from each district were selected purposefully based on their potential in cactus production. A total of 400 Cactus Grower and Non grower Households were selected to achieve the objectives of the study. Both qualitative and quantitative types of data were collected from sampled households. The quantitative type of data gathered from the respondents was analyzed using SPSS 20 versions whereas the data generated from group discussion and key informant interview were narrated and interpreted in the form of word. The descriptive result of the study indicated that Cactus feeding management includes the practices of cutting, scrubbing and chopping of young cladodes from branches of the stand for their animals and grazing. Regarding Cactus utilization in the study districts, farmers uses cactus pear for consumption (18.4%), live fence for crop field (13.7%), soil conservation (13.2%), and backyard live fence, (10.8%), for food security motive (9.9%), for forage (9.4%) and for wind break (8.5%) in the entire cactus growing areas of the study districts. Despite the fact that the vast majority of the respondents which accounts 61.3. % of the cactus growers reports they get unreasonable price from the sale of cactus due to lack access to potential market and low quality Cactus production, they obtained an average of 1007.9 Ethiopian Birr per annum. The study revealed that the income obtained from Cactus production was benefited 30.7% of farmers to cover their domestic consumables and purchase closes for their children. Also about 15.6% and 11.3% of the respondents were used the income obtained from the sale of cactus to cover costs of sending children to school and purchase improved crop varieties respectively. Regarding marketing constraints, the farmers indicated that Absence of Transportation facilities (20.3%), absence of market place (12.3%), low bargaining power (15.1%), perishability problem (17%), fluctuation of market price (9.4%) and availability of illegal brokers (14.2%) are the major problems they faces while selling their produce to the market. Regarding the income share of cactus grower and non grower Households it was found that the annual average income earned by cactus owner households were 13,910.6 birr whereas 12,371.3 birr for non cactus grower households with maximum earnings of up to Birr 30, 900 for non cactus grower and 35,960 for cactus grower households. Econometric result also reveals that the “average treatment effect on the treated” (ATT) for household income suggested, due to pure effect of cactus, the cactus owners obtain 1433.2049 birr of total income higher than non-owners; among which the mean difference of income between these two group is statistically significant at 5% probability level after matching. Considering the above mentioned fact, local government and other development partners should improve Access to market for cactus fruit so that farmers can get the best benefits from the cultivation of the crop.
