The study was conducted at the Horticultural Farm of Sher-e-Bangla Agricultural University, Dhaka, Bangladesh during the period from May 2013 to February, 2014. The experiment consisted three levels of mulch: M0 - control, M1 -Rice straw mulch and M2 - water hyacinth mulch. The experiment was laid out in a Randomized Complete Block Design (RCBD) with five replications. Application of different mulches showed significant variations on most of the parameters. The highest yield of spike (3,46,290/ha) was found from M2 and the lowest (3,07,140 /ha) from M0. So, water hyacinth mulch was found suitable for growth and yield of tuberose. Key word: Tuberose, mulching materials, growth and yield.

The agricultural sector is vital in economies of all countries all over the world, not only that agriculture sector provides food stuffs but also inputs to manufacturing sector and outputs to consumers and in all spheres at large. The agriculture sector contributes about 40% of worldwide employment and a 100% food production increase will be required in developing countries to feed the 2050 population, investment in agriculture sector is critical for driving global economic growth. The aim of this paper: The aim of the research was to investigate the contribution of agriculture finance in boosting agricultural yield in Gakenke district of Rwanda. Materials and methods: Data were collected using android mobile phone with application designed for data collection as the best quicker tool superior to paper based. A number of 66 respondents were selected proceeding snowball technique from two sectors of Gakenke district sampled by multistage sampling procedure with two stages, this method was employed due to it reduces cost and lessen the impossibility of getting list of respondents units. Results: Findings revealed a positive relationship between agriculture finance and agricultural yield whereby analysis of data showed that after acquiring agriculture credits, agricultural yield was tripled compared to the production before acquiring credits to invest in agriculture activities. Conclusion: In nutshell, as findings pointed out a positive relationship between agriculture finance and agricultural yield with a tremendous increase in agriculture yield than ever before investing in agriculture activities. The research recommended sensitization and encouragement to invest in agriculture activities to keep boosting agricultural yield and maintain welfare of farmers and nation at large. Keywords: Agriculture finance, Agriculture yield, Boosting agricultural yield.

In this paper investigations on a fixed speed wind farm with squirrel cage induction generators (SCIG) directly connected to the grid in combination with a STATCOM based Indirect Torque Control (ITC) under unbalanced grid voltage fault are given by means of theory and simulations and also different kinds of control methods are discussed. Under unbalanced grid voltage dips causes additional generator torque oscillations. The simulation results clarify the effect of voltage compensation by a STATCOM on the operation of a SCIG wind farm which inference the improvement of voltage stability and reduction of torque oscillation. Keywords: Voltage Stability, SCIG, Wind farm, low voltage Capability, STATCOM, Indirect Torque Control (ITC).

In this study, parameters for photocatalytic oxidation of reactive blue dye with zinc oxide as photo catalyst was optimized. Dye solution (10 mg/l) was used to contact with the zinc oxide catalyst under UV light at various reaction conditions viz; contact time; pH; and catalyst dose. The degradation of the dye was followed by measurement of absorbance of the solution using a UV Spectrophotometer adjusted at a maximum wavelength (λmax) of 629 nm with distilled water as the blank. The optimum conditions established for degradation were; catalyst dose of 5.0 g/l, a neutral pH of solution at 7.0, and contact time of 180 minutes (3.0 hours). Keywords: photocatalytic, oxidation, photocatalyst, degradation, reactive blue dye.

NoC is a scalable and flexible communication medium for the design of multi-core based SoC. Communication performance of NoC depends seriously on efficient routing algorithms. Fault-tolerant routing algorithm is the ability to survive failure of individual components. We evaluated a deterministic fault-tolerant, deadlock-free routing algorithm in two-dimensional (2D) mesh based topology on Fault-Tolerant-Routing (FTR) to increase performance of the messages over the on-chip interconnection networks. The FTR algorithm is a wormhole-switched routing for 2-D mesh networks and has been used for block faults. This algorithm uses virtual channels to pass faulty regions. We have evaluated the FTR algorithm by two different traffic patterns, hotspot and local, to show message delays and performance in the network which led to an Improved-Fault-Tolerant-Algorithm (i-FTR). Moreover, to simulate FTR and i-FTR algorithms, same network conditions namely network size, message length and number of generated messages has been considered. It can be deduced from results that i-FTR performance is better compared to FTR algorithm. Furthermore, results show that the interconnection network of NoC which has been used for i-FTR can deal with higher message rates and can tolerate higher traffic loads with higher utilization. Keywords: routing algorithm; wormhole switching; 2D-mesh interconnection networks; virtual channel

Scientific forecasting plays a vital role in financial markets for many decades. Forecasting methods of financial market were broadly classified into fundamental analysis and technical analysis. Fundamental analysis involves analyzing economic and firm specific factors while technical analysis is concerned with the price movements and trading volume in the market. Both approaches have been applied in forecasting share prices and stock returns. However, only a limited number of studies have been done on Sri Lankan share market. Existing forecasts made mainly based on Capital Asset Pricing Model has been proved unreliable in the Sri Lankan context. This study aimed to test the suitability of linear models, non-linear models and univariate causal models for forecasting share prices based on the data during 1994-2011 on randomly selected three banks listed in Colombo Stock Exchange (CSE). Findings suggest that univariate causal models were the most suitable in forecasting share prices of individual companies listed in CSE.

The study was conducted at Department of Seed Science and Technology, Tamil Nadu Agricultural University, Coimbatore during the period from July to October, 2007 to find out the effects of rainfall on physiological seed quality of grain amaranthus (Amaranthus hypochondriacus L.) cv. Suvarna. The results revealed that, grain amaranthus crop should be sown from early sowing in Kharif season harvesting higher seed yield with physiological seed quality. Between the crops, Kharif season was better than late sowing as the seeds would be exposed to rain and the rain discolored the seed and reduced its physiological seed quality of grain amaranthus.
