Abstract: Decisions making play a major role in the success of any organisation and individual. Business professionals are faced with making decisions that are predominately based on uncertain projections. Optimisation techniques have become key tools in making important business decisions that increase competitive advantage. Optimisation, through the use of mathematics and computer science techniques, is used to assist organizations with solving their complex business problems in areas such as productions, manufacturing, distribution, finance, and scheduling. The success of optimisation projects depends on many different factors such as which modeling tools are used, integration with corporate data, and the selection of the most efficient solution algorithms available for the problem. In this paper, we formulated and implemented a linear programming (hence forth LP) model for a small scale production company. Our model is good benchmark for effective managerial decision making for Production Company to foster optimal profitability. Our model was implemented with Java applet for portability.
Keywords: Optimization, Decision, Constraint, objective function, Linear programming.

Author(s): Nor Liyana Arif, Ahmad Makmom Abdullah, Hafizan Juahir, Loi Kok Chng
Pages: 7-14 Paper ID: 113905-1302-7272-IJBAS-IJENS Published: April, 2013
Abstract: Haze pollution has become a transboundary problem to the South East Asian region, especially Malaysia, Indonesia and their adjacent countries. Meteorological condition, particularly temperature, is severely affected during the haze episode which occurred between 1 August 2005 and 15 August 2005 in Klang Valley, Malaysia. This paper reports on the use of MM5 modelling system to predict the hourly temperature distribution during the haze period. Meteorological simulation was conducted to spatially and temporally analyse the temperature distribution during haze episode in Klang Valley. Domain resolution of 27km, 9km, 3km and 1km (innermost) have been employed for this study. Urban areas in Klang Valley experience higher temperature during the haze episode simulation. Highest daily maximum temperature for each day was recorded during late afternoon. Evaluation of the model performance was also conducted with a measured data through a range of statistical measures. The model tends to under predict the temperature distribution of the simulation period. The paper discusses the spatial and temporal distribution of temperature during the haze episode in Klang Valley and also the model performance in predicting the meteorological condition of the study area.
Keywords: MM5, Atmospheric Modelling, Urban meteorology, Haze.

Title: Study of Phytochrome Mediated Seed Germination of Cucurbita pepo L and Citrullus Vulgaris Thunb found in Balochistan
Author(s): Afroz R. Khan, Muhammad Anwar, Muhammad Javed Khan
Pages: 28-35 Paper ID: 137102-6969-IJBAS-IJENS Published: April, 2013
Abstract: The role of temperature and light has long been appreciated in the seed germination of plants; especially the control of seed germination by red and far-red light is one of the earliest documented phytochrome mediated processes. The seeds of Cucurbita pepo L germinated = 15 % when imbibed at constant temperatures of 15, 20, and 25 °C. The seeds were indifferent to far-red light. While seeds of Citrullus Vulgaris Thunb germinated = 10 % when imbibed at constant temperatures of 15, 20, and 25 °C. The seeds were indifferent to far-red light. Rate of germination was much reduced under far-red light. Mean value of seed germination % of Cucurbita pepo was high (36% ±16.09) at 25Co under dark, while it was lowest (14% ±6.26) at 15 oC under light. Conversely, germination % of Citrullus Vulgaris was high (21% ±9.39) at 25 oC under light, while it was lowest (2% ±0.89) at 15 oC under far red. At single pulse mean germination % of Cucurbita pepo at constant temperature (i.e. 20Co) was high (24% ±10.73) under red light, at intermittent Pulses while it was lowest (13% ±5.81) under red light.Alternatively, at single pulse mean germination % of Citrullus Vulgaris at constant temperature (i.e. 20Co) was high (26% ±11.62) under red followed by far- red light, but it was lowest (16% ±7.15) under dark.

Abstract: Background: Consumption of traditional foods high in fiber is on the decrease due to urbanization and westernization in Nigeria. Objective: The aim of this study was to formulate and develop nutritious snacks for urban diabetics using Afzelia africana and Detarium microcarpium seed flour. The nutrients, phytochemical composition and the sensory test were evaluated. Methods: The seeds of Afzelia and Detarium were purchased from the South Eastern Nigeria. The seeds were sorted and cleaned. Afzelia flour was produced using soaking and roasting method while detarium flour produced by boiling, soaking and milling. Recipes were formulated based on the soluble non-starch polysaccharide (s-NSP) content of the wheat flour and Afzelia and Detarium flour. The proximate composition, vitamin, mineral and phytochemical contents of the snacks were determined using standard methods. Sensory evaluation of the snacks was also evaluated. Data generated were analysed using Statistical Package for Social Sciences (SPSS) version 17. Results: The fibre content of snacks were; Afzelia (2.58-2.88%) and Detarium (2.34-2.49%). . The carbohydrate content was 47.18-50.18% (afzelia) and 57.63-59.35% (detarium). Retinol content was 2.63-7.87mg/100g and 5.24-5.26mg/100g for afzelia and detarium respectively. The tannin content was 0.63-1.03mg/100g and 0.60-0.62mg/100g; while the saponin content was 0.76-0.88mg/100g and 0.74-0.88mg/100g for afzelia and detarium respectively. Detarium snacks were more accepted for texture (7.62-7.70), colour (7.69-7.75), taste (7.31-7.70), crispness (6.89-7.35) and flavor (7.67-7.79) than afzelia snacks.

Title: Using Natural Clays and Spent Bleaching Clay as Cheap Adsorbent for the Removal of Phenol in Aqueous Media
Author(s): Bakhtyar K. Aziz, Fuad H. Shareef
Pages: 45-49 Paper ID: 137402-2626-IJBAS-IJENS Published: April, 2013
Abstract: Clay samples of six different locations of Kurdistan region were characterized. Chemical compositions of the clays were found using XRF technique for the clay powders. The mineralogy of the samples by XRD shows that the clay samples are mostly mixed layer type of Chlorite/Smectite composition with different types and quantities of mineral impurities. Specific surface area (SSA) and cation exchange capacity (CEC) for the clay samples were determined by methylene blue adsorption method. Although the de-oiled spent clays have less SSA and CEC compared with their virgin samples, but their adsorption efficiency is 70-80 % higher than their virgin clays due to the increase in the organophilic character of the de-oiled spent clays, while acid activation of the natural clays has no significant effect on the adsorption efficiency. Charcoal, the universal adsorbent, has removed 58% of 50 ppm phenol solution, while de-oiled spent clays have removed 80-95 % of the phenol concentration.
Keywords: Removal of phenol, de-oiling of clay, spent bleaching clay, adsorption efficiency.

Author(s): Aitkaly Nurseiit, Nurlan Nurseiit
Pages: 50-60 Paper ID: 138702-6565-IJBAS-IJENS Published: April, 2013
Abstract: The rapid developing of small and medium-sized business (SMBs) is an important condition for creating a stable and dynamic modern economy, especially in a transition country such as Kazakhstan, where since soviet era have been dominated super-large enterprises. The world experience shows that, if the government wants to make the growth of own economy more stable, it should create favorable conditions for the development of SMBs. In Kazakhstan, despite the measures of authorities, SMBs are still not performing that role that they have to play in the modern economy.

Title: Fabrication and Characteristics of Porous Silicon for Photoconversion
Author(s): Uday Muhsin Nayef
Pages: 61-65 Paper ID: 138602-3737-IJBAS-IJENS Published: April, 2013
Abstract: Porous silicon (PS) layers are prepared by anodization for etching time densities. The samples are then characterized the nanocrystalline porous silicon layer by X-Ray Diffraction (XRD), Atomic Force Microscopy (AFM), Fourier Transform Infrared (FTIR), Raman and electrical properties. PS layers were formed on a p-type Si wafer. Anodized electrically with a 10, 20 and 40 min etching times for fixed 20 mA/cm2 current density. We have estimated crystallites size from X-Ray diffraction about nanoscale for porous silicon and AFM confirms the nanometric size and therefore optical properties about nanocrystalline silicon yields a Raman spectrum showing a broadened peak shifted below 520 cm-1. The electrical properties of prepared PS; namely current density-voltage (J-V) characteristics under dark, and illuminations show that the pass current through the PS layer decreased by increasing the etching time, due to increase the resistivity of PS layer. The photosensitivity measurements of prepared PS layer showed the peak value in visible region at (400-600 nm) increased with increasing the etching time.
Keywords: Porous silicon, X-Ray Diffraction, Raman, morphological properties, Raman, J-V, Photosensitivity.

Title: Study of Radiation and Matter Epochs of the Universe
Author(s): Mariwan A. Rasheed, Mohamad A. Brza
Pages: 66-69 Paper ID: 1311302-4848-IJBAS-IJENS Published: April, 2013
Abstract: Some basic properties of the universe at two different epochs of radiation and matter were calculated depending on lambda cold dark matter model. WMAP satellite data and a computer program code used for solving Friedmann equations and calculating radiation density, matter density and temperature at different ages of the universe from the Big Bang to the present day. It was found that the value of radiation, matter and dark energy densities were different in the same value of the age of the universe, except approximately at years the density parameter of radiation and matter were equal. Also it came to be known that when the age of the universe is increased, temperature decreased so matter dominated in the universe. At temperature 3K the cosmic microwave background radiation separated freely all over the space.

Abstract: In analogous to classical ordinary differential equations, we study and establish results on converse variational stability of solution of quantum stochastic differential equations (QSDEs) associated with the Kurzweil equations. The results here generalize analogous results for classical initial value problems. The converse variational stability guaranteed the existence of a Lyapunov function when the solution is variationally stable.
