Determinants of equity return: Syariah and Non-Syariah complaint firms the case of Pakistan
The study investigates the significant determinants of stock returns of all non-financial listed companies in Karachi Stock Exchange (KSE), Pakistan from 1998-2011 by using panel data techniques. In addition, this study further categorized into Syariah and Non-Syariah compliant firms to examine the significant differences of stock determinants. All listed stocks in Karachi Meezan Index (KMI) are entitled as Syariah complaint firms, rest of the firms listed in KSE all index are identified as non-Syariah complaint firms. As Syariah complaint firms don’t use any unethical means to cater its stock prices, so, it was hypothesized that Syariah stocks follow the fundamental of the companies. Size, book to market, leverage, dividend yield, earning to price, cash flow to price and discretionary accrual represents the fundamentals while market premium, stock price volatility and trading volume indicates the stock market variables. Fixed effect model and Random effect model is applied for statistical estimations. Hausman test is further used to find the most significant model. Modified wald test find the heteroskedasticity, final results were robust to counter the heteroskedasticity issue. The results of all non-financial listed firms confirmed the significant positive market premium, size, stock price volatility and trading volume whereas significant negative book to market ratio. Market premium, leverage and stock price volatility are the only significant determinants of Syariah complaint firms. Insignificance of BM and TV confirms that Syariah stocks follow the fundamentals instead of noise trading. In a nutshell, Syariah complaint firms respond to fundamentals although non-Syariah complaint firms follow noise trading in Pakistani context.

Diagnosis of learning difficulties in English: the Arabic bilingual context
Education in general and language education in particular usually poses great problems to those who don’t have a favourable academic environment. The case of ESL/EFL/ESOL is always a challenging task. English in most Arabic speaking countris serves a very limited purpose. Yet, it is very important for social as well as technological development. Therefore, English language teaching (ELT) in such countries also catches attention of many researchers. ELT generally starts at the school level. Despite good overall planning, purposive curriculum, integrated textbooks, qualified teachers, the achievement is below the expectations. Therefore, diagnostic studies should better be undertaken in different language areas: sound system, vocabulary, meaning, grammar and various skills so that the teacher may know the types of the problems and the corresponding factors. Such attempts are expected to be helpful in possible evolution of some fruitful and compatible strategies in order to yield the maximum academic output.

Digitalis toxicity during acute renal failure associated with multiple myeloma: A considerable risk
Digitalis (cardiac glycosides) is a naturally occurring substance in various plants (digitalis, squill). They are mainly used in the treatment of heart failure and cardiac rhythm disorders. They induce a positive inotropic effect by inhibiting NA+/K+-ATPase which results in an increase in the amount of calcium released from the sarcoplasmic reticulum in each cycle of contractions. Digitalis toxicity is a rare drug complication, but potentially serious. This is rare when good rules of drug prescription are respected, though this is not often the case. This highlights on the need for further information to physicians and their patients about the risk involved, including renal failure and electrolyte imbalance (hypercalcemia, hyperperkalemia, hypokalemia etc.).

Do we still have an impact of global crisis in Indian economy today?
The global financial crisis, brewing for a while, really started to show its effects in the middle of 2007 and into 2008. Around the world stock markets have fallen, large financial institutions have collapsed or been bought out, and governments in even the wealthiest nations have had to come up with rescue packages to bail out their financial systems. Indian economy began to slow down in 2007-08 (April-March) after reaching a GDP growth of 9.8 per cent in the last quarter of 2006-07. In fact, Indian economy grew at an annual average rate of 8.8 per cent during the five years ending 2007-08. In the first half of the financial year 2008-09, the growth rate dropped to 7.8 per cent. The global crisis has hit India through a “sudden stop” of capital inflows and a collapse of both external and domestic demand. The growth of the economy dropped to 6.7 per cent in 2008-09 from 9.0 per cent in the previous year and is slowly increased to 8% in 2009-10 and 8.5% for the financial year 2010-11. The present paper is an attempt to analyze the impact of global recession on Indian economy, how the Indian economy recovered and also analyze whether the global crisis still influencing the Indian economy

Dye Removal Using Some Surface Modified Silicate Minerals
The objective of this work is to study the efficiency of some surface modified phyllosilicate minerals (bentonite and glauconite) in the removal of dyes from textile waste water. It is found that complete dye removal was achieved by using (10-25) g modified glauconite from solutions having a dye concentration of 10-50 mg/L. Adsorption data were modeled using Langmuir, Freundlich, Temkin and Dubinin-Radushkevich isotherms. Adsorption capacities and optimum adsorption isotherms were predicted by linear regression method. The analysis of experimental isotherms showed that Langmuir isotherm reasonably fit the experimental data in the studied concentration range for the adsorption of dye onto glauconite mineral surface where Freundlich isotherm fit the experimental data for the adsorption of dye onto bentonite mineral surface.

Effect of cassava peel ash on lateric soil stablized with bitumen
The effect of cassava peel ash on Lateritic Stabilized with Bitumen was investigated. The lateritic solid was collected from Umuma-Isiaku in Ideato South LGA of Imo State. The Bitumen was collected from New Idea Construction Company Ltd in Owerri. The Cassava peel was collected from Ohaji in Egbema LGA OF Imo State. The Cassava Peel was burnt in a furnace and sieved with 150% sieve to obtain the ahs used in the experiment. The lateritic soil was classified as A-2-7 on AASHITO classification chart. The percentage replacement level of soil by Bitumen and Bitumen/cassava peel ash 0-10% by weight of dry soil. The investigation was carried out with respect to compaction Characteristic and California Bearing Ratio (CBR) tests. The result obtained indicated a decrease in maximum Dry Density (MDD) when the soil was stabilized with bitumen and increases when cassava peel ash was incorporated for 0-10% replacement level of soil with bitumen and bitumen/cassava peel ash respectively. The result of the optimum moisture content (OMC) increases when bitumen was used in stabilizing the soil and decreases when cassava peel ash was incorporated. The result of the MDD when bitumen was used in stabilizing the soil ranges from 2.16-1.76gkmcm3 for 0-10% replacement of dry soil with bitumen and 2.16-4.20g/cm3 when cassava peel ash was incorporated. The results of OMC ranges from 11.20 -21.90% and 11.20-8.80% for 0-10% replacement of dry soil with bitumen and bitumen/cassava peel ash respectively. The result of CRR text ranges from 22.66-85.75% and 22.66-18.10% for the same replacement level of bitumen and bitumen/cassava peel ash respectively. These results shows that the high shear strength of soil which was achieved by stabilizing the soil with bitumen was reduced by the incorporation of cassava peel ash.

Effect of Poultry Manure and Planting Arrangement on the Soil Physico-chemical Properties and Yield of Sesame/Groundnut Mixture
In recent time, there is increasing interest in diversified agricultural production systems to obtain higher yields per unit area through better use of natural resources, minimizing the incidence of insect pests and diseases, greater stability and crop insurance offered by intercropping systems. Field experiment was conducted during the rainy seasons of 2011 and 2012 at the Teaching and Research Farm of the Faculty of Agriculture, Nasarawa State University, Keffi – Lafia Campus to study the effect of poultry manure and planting arrangement on the soil physico-chemical properties and yield of Sesame/groundnut mixture. The experiment consisted of four rates of poultry manure (0, 3.0, 6.0 and 9.0 t ha-1) and two planting arrangement (single alternate row and double alternate row planting arrangement). The eight treatment combinations were laid out in randomized complete block design with four replications. The results obtained showed that the soil physical structure was slightly improved; total N, available P and organic carbon of the experimental soil were increased by 20, 62 and 6% respectively after the experiment. Yield and yield characters of the two crops were significantly increased by the application of 6 t ha-1 of poultry manure and double row planting arrangement. Land equivalent ratio was greater than unity indicating that the intercropping system was advantageous.

Evaluation of novel Semicarbazones as corrosion inhibitors for mild steel in acidic solutions
Corrosion is the primary means by which metals deteriorate. Most metals corrode in contact with water and also moisture in the air, acids, bases, salts, aggressive metal polishes and other corrosive solids and liquid chemicals. A suitable, effective and economical method has to be adopted depending upon the metal and its environment. Mild steel is of high industrial value. Metals, when subjected to surface treatment such as painting, enameling etc. should have clean surface, free from rust or oxide scales. For removing these rusts and scales, metals are immersed in acid solutions known as acid pickling bath. Generally hydrochloric acid is used in pickling bath. However, now- a- days sulphuric acid has replaced hydrochloric acid as pickling solution due to its economic advantage.
