Pigeon pea [Cajanus cajan (L.) Millsp.] is the rich sources of dietary protein, carbohydrate & certain minerals but its poor yield needs to formulate a nutrient management practices for higher productivity in upland alfisols of Tripura and to combat it, an experiment was conducted during three consecutive kharif seasons at College of Agriculture, Lembucherra, Tripura comprising of two levels of Lime (150 and 200 kg ha-1) in main plot and two levels of molybdenum seed treatment (0 and 4g kg-1 of seed) in sub plot and 4 levels of recommended doses, viz 0% of RDF ha-1, 50% of RDF ha-1, 75% of RDF ha-1 and 100% of RDF ha-1 (Recommended dose @ 20:60:40 of NPK). It was revealed that by the use of 100% RDF ha-1 with 150 kg ha-1 lime and 4g kg-1 of molybdenum seed treatment leads to higher yield and return per rupee respectively. But by the use of 100% RDF ha-1 with 200 kg ha-1 lime and 4g kg-1 of molybdenum seed treatment, return per rupee was recorded at 2.98. The investigation reflects that by the use of 75% RDF ha-1 return per rupee (3.78) was less compared to 100% RDF ha-1 but significant with saving the cost of 25% RDF ha-1 and soil health from the excessive use of fertilizer for sustaining the agricultural growth.

Security has become the greatest problem within and outside the organizations. User ID, passwords and firewalls are the common steps that organizations take to secure their computers. However, these are not so effective mediums in current context of unsecure eon. Intruders and attackers are so advanced that they access the computer and manipulate it, so they cannot be traced easily. Through this contribution objective is to find out & present existing intrusion detection system (IDS) with their pros and cons that will be helpful to select the best one and provide the secure environment so that system will be protected from instrusion and attacks.

In this paper we have investigated the steady plane poiseuille flow of viscous incompressible fluid between two porous parallel plates in magnetic field. We have studied the velocity, average velocity, shearing stress, skin frictions, the volumetric flow, drag coefficients and stream lines.

We have studied the velocity, average velocity, shearing stress, skin frictions, the volumetric flow, drag coefficients and stream lines.

Speech act theory is a widely disputed field and issues such as what speech acts are and how they are classified seem to be culture specific, and not as universal as some of the studies presented above have described. Evidence on speech act production and recognition from different cultures have demonstrated that more research needs to be done in order to provide a theory that has an integrated approach to speech acts. Thus, besides carefully defining the term used in the research and creating an appropriate taxonomy, social, cultural, and pragmatic influences on the meaning, perception, and production of speech acts need to be considered. This study aims at comparing the strategies used by Native English speakers and Iranian EFL learners for expressing promising in different situations. The participants of this study were 27 among whom 20 were Iranian EFL learners and 7 were native English speakers. The participants were both male and female, aging from 18 to 31 years old. An open-ended data collection technique (DCT) was employed for studying participants' responses and verbal reactions to different situations. Iranian EFL learners’ sensitivity to L1 made them use inappropriate expressions and strategies in their English responses. It suggested that Persian learners of English transfer some of their L1 pragmatic norms to L2 because they perceive these norms to be universal.

This study explored the impact of resiliency and protective factors in academic achievement among primary school pupils from refugee camps in Dadaab, Kenya. The data was collected from 188 pupils (132 males and 56 females) and 22 teachers selected from standard five to eight classes in 22 refugee primary schools. Both school and participants were selected randomly.A questionnaire was used to measure resiliency and the mean mark (MM) of the first term to measure the academic performance of the participants. The data was analyzed using descriptive and inferential statistics. T-test was used to compare male and female participants in resiliency and academic achievement. The ANOVA was used to compare the relationship between resiliency and academic achievement. The results of the study showed that there was significant differences between male and female pupils resiliency and academic achievement. Similarly, there was significant differences between pupils’ resiliency and educational class levels. Further results revealed that most pupils in refugee schools achieved poorly in academics, while most girls dropped out of school due to cultural barriers. Majority of the pupils were ignorant of protective factors to safeguard perceived risks such as family and society related risks. From the findings, it was recommended that different authorities from UNHCR and related humanitarian assistance organizations or counseling services at the schools ought to improve pupils’ psychological resiliency and provide support to help overcome risks and focus on academics with high level of self-efficacy to achieve.

Seaweeds are the potential marine living resources in the world. More than 20,000 seaweeds are distributed throughout the world, of which only 221 (1.1%) are commercially utilized, which includes 145 species for food and 110 species for phycocolloid production (Sahoo, 2000). During September 2011 to March 2013, extensive field surveys were conducted to Kerala coast and a total of 137 species of seaweed were recorded. Based on the review of available literature, totally 42 species were found economically important. Of these, 29 species are edible for humans, 24 species are suitable for industrial sector to extract the phycocolloides (agar-agar, agaroids, algin, carageenans etc.), 14 species used as fodder for domestic animals, 11 species for the production of manures in the form of Seaweeds Liquid Fertilizers (SLF) and 7 species suitable for various medicinal purposes. The red seaweeds are dominant with 19 species, followed by green seaweeds with 14 species and brown seaweeds with 9 species. The rich diversity and luxuriant growth of seaweeds were recorded at Mullur Kadalapuram, Vizhinjam, Kovalam, Varkala, Edava, Thangassery, Thirumullavaram, Baypore, Thikkodi, Mahe, Ezhimala Manjeshwar and Hosabettu coasts. The presence of natural rocks, bedrocks, the artificially made cement boulders and laid stones along the coast support the growth of a large number of seaweeds.

Life is a journey. The way time flies. Three decades of academics, research and charity packed life. From 1984 – 2014 the pedestal has been on to shape tropical agriculture, capture temperate agriculture, and serve humanity in all spheres of life. Most rewarding is the metamorphosis in academics and charity at local and cross-country levels. There can be no better tribute to my lecturers, supervisors, students, bosses, schools, colleges and universities than to review this personal three decades of experimentation in tropical Nigeria.

Data worldwide is growing 40 percent per year, a rate of growth that is daunting for any organization. Big Data Analytics is becoming an increasingly important part of every aspect, batch processing system like Hadoop had evolved for excellent offline data processing platform for Big Data. There are many use cases across various domains which require real-time / near real-time response on Big Data for faster decision making. This paper describes beyond batch processing system towards Real-Time and Streaming.

This work was carried out in order to optimize the friction phase parameters, of friction welding of M2 high speed steel, to AISI 1040 medium carbon steel, namely; rotational speed, friction pressure and friction time. The experiments were designed as per Taguchi method. The optimization of the experimentally obtained results was carried out by trying three mathematical models, namely; a multiple linear regression model without interaction effect, a multiple linear regression model with interactions effect, and a second-order polynomial regression model. The three models were evaluated using the experimental data, the coefficient of multiple determination R2, and Standard error of the regression (S), were used as the evaluation criteria of the models. The polynomial model was chosen, and optimized using a Genetic Algorithm. The optimal value of the joint strength of 411 MPa was obtained at the highest value of the time ( 44.9 sec.) and the pressure of 112 MPs and the speed of 1349 r.p.m.
