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.).

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

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.

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.

The study was designed to evaluate the effects of moist heat on the nutritional, anti-nutritional and phytochemical composition of the nuts of Tetracarpidium conophorum (African walnut). African walnut was subjected to cooking at 100oC. The raw and boiled nuts were chopped and air-dried. The nutritional composition of Tetracarpidium conophorum investigated on shows: protein(%) 26.83, 25.90 and 26.23; crude fibre (%) 1.50, 1.20 and 1.10; fat(%) 16.36, 16.43 and 16.43; carbohydrate (%) 42.33, 43.60 and 44.63; moisture (%) 9.17, 9.33 and 8.92; ash (%) 3.80, 3.53 and 3.33 for all the samples of raw air dried, boiled air dried and boiled oven dried respectively. Evaluation of anti-nutritional factors (mg/100) revealed, phytates 31.67, 16.67 and 13.33; oxalates 12.17, 7.83 and 5.33 for raw air dried, boiled air dried and boiled oven dried respectively. Analysis on the phytochemical composition of the walnut (mg/100) revealed, alkaloid 12.32, 7.33 and 6.67; saponin 21.67, 13.33 and 8.33; flavonoids 2.33, 2.47 and 2.50; terpenoids 7.67, 9.23 and 6.40; steroids 12.30, 12.37 and 12.10; phenolics (GAEG) 35.10, 28.37 and 20.17; ORAC (% inhibition) 46.30, 32.50 and 25.10 respectively on the raw air dried, boiled air dried and boileded oven dried. With respect to the findings, there were significant (p>0.05) decrease in all the samples on the nutritional, anti-nutritional and phytochemical compositions of the samples except the fat and carbohydrates that showed increment on the compositions through raw air dried, boiled air dried and boiled oven dried processing. The moisture content of boiled air dried recorded highest among the samples, while the phytochemical compositions revealed the steroids to be stable in all the samples.

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.

A study on electro less plated yarn charactertics through Box Behnken Design by various the sliver nitrate amount, temperature and time has been reported. The cotton and polyester yarns were plated with sliver nitrate by electroless plating at various concentration, temperature and time. The surface morphology, antimicrobial activity, electrical conductivity, strength and elongation have been measured for cotton and polyester silver plated yarn. It is observed from SEM image that deposition and firm attachment of sliver particle over the surface of yarn structure. It is also observed that the sliver plated yarns have better antimicrobial activity, electrical conductivity and strength than normal yarn.

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.

The main aim of present study is to examine the impact of environmental uncertainty (market ) , the investments and the quality of information available to the authority of the investments of accepted Tehran Stock Exchange listed companies , as well as the increasing introduction of a new theory named the actual authority .The investment authority in asset capital also like authority is on financial assets with the difference that these authorities appear on the real assets such as the land , building , machinery and other physical assets. By using the traditional methods of assessing projects such as the method of cash flow reduction (net present value and internal rate of return). With regard to the elements of environmental uncertainty, managerial authority and flexibility in projects and investments lead unrealistic assessment. So with regard to these drawbacks to use theory of investment authority and its effects in the value of the company and determining its value could be a great help to the better and more real assessment of projects and investments. So in case this question arises that with regard to this point that managers have such authority, how they regard the structure and the logic of investments authority in the analysis and designing their projects with a view to environmental uncertainty, the cost of investment, riskless interest rate and the quality of the information available for the company ?. For this purpose by using public formula of Cochrane a sample including 163 financial directors of the corporate (manufacturing) of Tehran Stock Exchange reviewed their views and opinions about the investments authorities. And also to analyze the data the linear regression was used. By regarding the conducted surveys it become clear that based on the above - mentioned managers points of view the independent variables ( environmental uncertainty , riskless interest rate, cost of investment and the quality of the information available ) have a significant impact on investment authority .
