Aziz Khan, Fazal Munsif, Kashif Akhtar, Muhammad Zahir Afridi, Zahoor  , Zahoor Ahmad, Shah Fahad, Rizwan Ullah, Faheem Ahmed Khan, Mairaj Din
American Journal of Plant Sciences (AJPS) , 2014, DOI: 10.4236/ajps.2014.515246
Abstract:

Nitrogen (N) and Phosphorus (P) are of the most important and complex nutrients for the crop plants in particular for grain yield and quality. The field trials were laid out in randomized complete block design having three replications. Research trial plots were located at Agricultural Research Farm of Agricultural University Peshawar (Ameer Mohammad Khan Campus Mardan) during kharif season in 2012 to investigate the response of maize variety (Jalal) to three phosphorus rates (60, 90 and 120 kg·ha-1) and four nitrogen rates (90, 120, 150, 180 kg·ha-1) for agronomical traits. These traits investigated included number of plant per m2 (NP m2), plant height (PH), number of leaves plant-1 (NLP), leaf area plant-1·cm2 (LAP), fresh weight of plants kg·ha-1 (FW) and dry weight of plant kg·ha-1 (DW), were investigated. Results of the study showed that application of N @ 180 and P @ 120 kg·ha-1 significantly increased fodder yield of maize. The linear increase in biomass yield clearly indicated that N was a limiting nutrient factor and that N demand along with P has a positive response. At higher application rates, N fertilizer significantly

Modeling Municipal Solid Waste Management in Africa: Case Study of Matadi, the Democratic Republic of Congo  [PDF]
Gregory Yom Din, Emil Cohen
Journal of Environmental Protection (JEP) , 2013, DOI: 10.4236/jep.2013.45052
Abstract:

The purpose of this article is to present the key elements for best performance and profitability of Municipal Solid Waste (MSW) management in a low-income city. The research provides an overview of methods and models for integrated planning of a two-phase program: MSW collection and transportation, and MSW treatment. We present the case study of Matadi (the Democratic Republic of Congo) that has a low level of the MSW management compared to other African cities. We develop a spreadsheet model for collection and transportation of MSW which is relevant for low-income cities and enables determining the waste collection fee. A CDM decay model is used to predict the GHG emissions in disposal site. The MSW treatment plant in case of Matadi is evaluated. For the anaerobic digestion technology selected as appropriate for this plant, the key factors that ensure profitability of the plant are as follows: tipping fee from the municipality (19% of total revenue), amount of carbon credits which can sum up to 16% of the total revenue, expansion of waste collection range from 25 to 50 km. The methods of this study can be used for solving waste problem in other low-income cities where the budget for municipal services is scanty, particularly when starting from a very low level of MSW management.

Adaptation of generalized Hill inequalities to anisotropic elastic symmetries

International Journal of Engineering, Science and Technology , 2011,
Abstract: Mechanical and elastic behaviors of anisotropic materials are investigated in an innovative way. This is based on generalized Hill inequalities. From different type of anisotropic elastic symmetries, numerical examples are given. Constructing bounds on effective eigenvalues provides a deeper understanding about mechanical behavior of anisotropic materials. Generalized Hill inequalities are adapted to all anisotropic elastic symmetries. The materials selected from the same symmetry type which have larger interval between the bounds, are more anisotropic whereas smaller interval between the bounds, are closer to isotropy. Besides it is proved that there are relations between bulk and shear modulus and eigenvalues of cubic and isotropic symmetry and by these relations, two linear invariants are found out.
The two sector model of learning-by doing and productivity differences

Panoeconomicus , 2012, DOI: 10.2298/pan1205583d
Abstract: This paper proposes that even when all countries have access to common technology frontier and can use the technologies which are fully appropriate to their needs, there will still be productivity differences across countries depending on their relative skill endowments. To illustrate this view, we have constructed a two sector model of productivity differences in which the level of technology is determined endogenously depending on the aggregate capital externalities. The relative supply of skilled and unskilled labor determines the direction of technical choices of the countries and differences in these relative factor supplies lead to cross-country income differences combined with the fact that capital is more productive in the advance of the skilled labor complement technologies than in the unskilled labor complement technologies.

Abstract: As shown by the ideas that are scattered to a wide spectrum, of ordinary people and academicians, who come from a variety of socialization backgrounds, defining Europe and the Europeans is not easy. Still, analyses on the historical and current shaping of European Identity, based upon views of the politicians, thinkers and academicians, information and views of the ordinary citizens collected through surveys, are necessary. This study aims for a better understanding of European Identity, by drawing attention to the views of experts and current anxieties of Europeans. The proposed models for creating a stronger European Identity and different perspectives with regard to the current problems are touched upon in order to show how European Identity is perceived from within and outside of Europe. Given the very different views of key figures and ordinary citizens with regard to the desired form of European Identity, it could be concluded that the glue keeping Europe together is not a shared identity but shared projects and targets.

Pakistan Journal of Biological Sciences , 2008,
Abstract: The present study was designed to evaluate different honey samples obtained from local market for their quality parameters for assessment of their feasibility for foreign export by comparing it with international standards. The study was conducted at PCSIR laboratories complex, Peshawar, during 2006. The tested samples were evaluated for moisture content, Ash percentage, acid content, HMF and reducing sugars percentage. The moisture content of locally produced honey was in the range of 14.5 to 18.23%. The ash content of locally produced honey samples ranged between 0.047-0.35 which is within the standard limits. The acid content of the honey samples ranged between 19.5 and 38.0 meq kg-1. The HMF contents of locally produced honeys ranged from 5.3 to 23.20 mg kg-1. The content of reducing sugar of the tested samples ranged between 43.14 and 81.40% for the tested samples of locally produced honey. All of the samples were found to be in acceptable range of international standards for all of the tested parameters except for only one sample with lower reducing sugars. These samples were marked to be according to the international standards and are healthy for human consumption.
Assessment of different crop nutrient management practices for yield improvement

Australian Journal of Crop Science , 2008,
Abstract: Food security could only be attained with increasing crop productivity. One of the major crop productivity constraints is the unavailability of crop nutrients. Both macro and micro nutrient deficiencies have been reported in most of the soils, which could be provided through various nutrient management practices. Different nutrient application measures were studied for their impact on crop yield and yield-related parameters in a series of experiments, conducted at agricultural research farm, NWFP Agricultural University Peshawar, Pakistan from 2004 through 2007. FYM application was observed to improve crop growth and yield of different wheat cultivars. Nutrient seed priming resulted in better early growth of maize. At field level, nutrient seed priming improved performance of wheat. Similarly for maize crop, nutrient seed priming resulted in more number of cobs plot-1, grains cob-1, 1000-grain weight and biological yield of maize crop even at lower soil application. Soil application of P improved yield and yield components. Better results were obtained from combined use of priming and soil P application. Foliar application of macro and micro nutrients also produced better crop yield and yield components. Similarly, foliar application of micro nutrients (zinc and boron) improved yield over two years. Our results show that all of these crop nutrients management practices has a positive impact on crop performance and call for an integrated approach of crop nutrient management. Such integrated approach must be evaluated at farm level for their economic impact. Adoption of integrated crop nutrient management techniques could be more economical and environmental friendly to achieve higher yields and thus food security.

Abstract: The objectives of this study were to use the dry thyme leaves as source of nonhaeme iron and evaluate the effects of calcium, phosphorus and calcium + phosphorus on nonhaeme iron absorption and haematogenic characteristics in rats. Thirty adult male albino rats, weighing 150 ± 5 g were divided into five groups. The first group fed basal diet, the second group fed thyme diet, the third group fed thyme diet + calcium, the fourth group fed thyme diet + phosphorus and the fifth group fed thyme diet + calcium + phosphorus. All groups fed experimental diets for six weeks. Hemoglobin (Hb), haematocrit (Ht), red blood cell (RBC), mean corpuscular volume (MCV), serum iron (SI), serum ferritin (SF), total iron–binding capacity and transferrin saturation were determined at the beginning and the at end of the experiment. Iron in diet, Fe intake, Fe feces and Fe absorption were also evaluated. The results indicated that the lowest Fe absorption was observed in rats fed the thyme diet + calcium and thyme diet + calcium + phosphorus. Supplementation the thyme diet with calcium or calcium + phosphorus decreased the values of Hb, Ht, RBC, SI and SF. However, supplementation the thyme diet with phosphorus did not affect in Ht, RBC and MCV but Hb, SI and SF increased. The results suggest that supplementation the diet with calcium or calcium + phosphorus interfere with iron absorption.

Agricultural Sciences (AS) , 2010, DOI: 10.4236/as.2010.11006
Abstract: The present study was conducted to analyze cotton cultivar and location differences in motes, and to determine the relationships among these and ginning outturn. Therefore, the seed cotton of five promising hybrids namely; G.77 × Pima S6 and G.84 × (G.74 × G.68) growing in [Kafr El-Sheikh - Kafr El-Dawar - Etay El-Barood - Damietta], G.89 × Pima S6 growing in [El-Sharkia - El-Gharbiya - El-Dakahliya - El-Monofiya], G.83 × (G.75 × 5844) × G.80 and G.90 × Australian growing in [Sohag - El-Minia - Beni-Sueif - El-Faium] were used in this study. The results obtained indicate that the varieties exhibited different behavior responses to environmental conditions. On the whole, environmental factors associated with differences in place of growth, appeared to have much more influence on the number of motes than did varietal factors. Most of the locks for the promising hybrids at the different locations tend to cluster around the mean of 6 or 7 seeds per lock. There is a fairly marked tendency for the lock index, lint weight and lint percentage to decrease as the motes percentage increase. On the other hand, most of the promising hybrids under study tend to increase in the seed index as the motes percentage increase. However, the increasing in seed index as a result of the increasing in motes percentage for some cotton cultivars growing at different environments could be explain the difference in behavior for these cotton cultivars in lint percentage.
