Information and communication technologies (ICT) have become commonplace entities in all aspects of life. Across the past twenty years the use of ICT has fundamentally changed the practices and procedures of nearly all forms of endeavour within business and governance. Within education, ICT has begun to have a presence but the impact has not been as extensive as in other fields. Education is a very socially oriented activity and quality education has traditionally been associated with strong teachers having high degrees of personal contact with learners. The use of ICT in education lends itself to more student-centered learning settings and often this creates some tensions for some teachers and students. But with the world moving rapidly into digital media and information, the role of ICT in education is becoming more and more important and this importance will continue to grow and develop in the 21st century. This paper highlights the various impacts of ICT on contemporary higher education and explores potential future developments. The paper argues the role of ICT in transforming teaching and learning and seeks to explore how this will impact on the way programs will be offered and delivered in the universities and colleges of the future.Keywords: Information and communication technology (ICT), constructivism, conventional teaching, education curriculum.
In this paper the Proposed new scheme in order to implement an MMSE Channel estimator for an OFDM System we know that the time domain maximum likelihood estimators (MSE) Can achieve highly accurate impulse response estimation by using time domain long preamble of an OFDM frame. The Least Square algorithm is easier for the channel estimation. The impulse response estimation based on the minimum mean square error (MMSE) Criterion can achieve superior channel estimation in low SNR conditions.Keywords: Channel Estimation, OFDM, Training Symbol, Pilot Structure, Bit error rate.
Collaborative learning is essential because higher mental functions such as reasoning, critical thinking and reflection originate in social interactions and are then internalised by the individuals in the group. The purpose of this study was to investigate the effectiveness and affectiveness of collaborative learning in the elementary mathematics classrooms and to designate studentsâ€™ perception on the process of collaborative learning. The sample of the study was 207 Class VII students in 5 (2 Govt. and 3 private) schools of Delhi. It was an experimental study with controlled group taught with traditional teacher led individual learning technique whereas the experimental group was provided with Collaborative learning Technique using Jigsaw model of grouping. In the study, the Collaborative Learning Process Scale and the Mathematics Achievement Test were used to collect data. In the light of the findings, it can be put forward that cooperative learning has a positive effect on student achievement. The cooperative learning activities done in the experimental group have meaningfully increased the student achievement, social skills, interpersonal relations as well as readiness to participate, share and initiate in learning process.Keywords: Affectiveness ,Collaborative Learning, Effectiveness ,Jigsaw Technique, Mathematics Achievement.
The steeping time and water temperature is very important in determining ideal taste of tea. The optimum water temperature and steeping time only gives good quality tea liquor. Lesser steeping time and lower water temperature adversely affects the liquor quality. Higher steeping time also result in low quality. Medium steeping time with higher water temperature gives good liquor quality, with higher theaflavin, thearubugin and total liquor colour.Keywords: Theaflavin, Thearubigin, liquor, colour, time and temperature.
The construction of any types of roads paved/unpaved roads over the weak subgrade soil is challenging task to civil engineering within the economic cost. The weak subgrade soil associated with poor properties such as high swelling, shrinkage, compressibility, and settlement. The properties of this soil are encounter as a Black cotton soil (BC). Due to the lower shear strength of the BC soil, the failures are the caused in the low-volume roads such as rutting, fatigue and reflecting and the high settlement. To arrest this problem in the pavement many of the conventional Stabilization techniques were adopted in the pavement engineering. In the present study, an attempt is made in the laboratory to evaluate the performance of the coir geotextile fiber to enhance the weak subgrade soil by the stabilization method by using the cement. The Stabilization is a process to change the soil properties to enhance strength and bearing capacity of the weak sub-grade soil. From the last three decades, several studies are done on the usage of natural fiber material to improve the characteristics of weak soils. The coir fibers serve as functions like Reinforcement, erosion control etc. In this paper, the present investigation conducted with a sub-grade as black cotton soil with adding of various percentages of coir fiber (0.25, 0.5, 0.75 and 1 %) and percentage of cement (5 %) by weight of the soil. The CBR test is conducted at the soaked and un-soaked condition with adding of cement and curing period of 0, 7, and 28 days. The study was also conducted along with cement and adding of coir fiber in both the test. The study results are concluded that the coir percent (1 %) in both un-soaked and soaked conditions. Similarly, the CBR test found that maximum compressive strength also obtained at coir (1 %), the inclusion of coir improved the compressive strength and bearing capacity and also the increase in CBR values with increasing the percent of coir fiber and found that (1%) of coir is optimum in un-soaked and soaked condition. The use of coir fiber along with the cement gives additional reinforcement to the Low-volume roads and improved the service life of the pavement.Keywords: Stabilization, Reinforcement, Coir fiber, CBR.
An investigation consisting ten treatments with focus to identify the effect of intercropping and tillage on carbon sequestration under soybean-pigeonpea cropping system was formulated during 2014-15 at Research Farm of Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola (MH). The experiment has stressed on soil microbial biomass carbon, dehydrogenase activity (DHA), potassium oxidizable carbonunder minimum tillage and intercropping with green manure crop (sunhemp). Based on the data generated it was noticed that significantly increased the carbon dynamics. Similarly, other relevant soil properties were also significantly influenced. The maximum amount of soil microbial biomass carbon and DHA was found in treatment where, pigeonpea intercrroped with sunhemp under minimum tillage compared to sole pigeonpea under conventional tillage.Keywords: Organic carbon, microbial biomass, carbon, DHA.

The purpose of this study was to examine the effect of organizational culture on organizational commitment at public hospitals in Addis Ababa. Organizational Culture Index and Organizational Commitment Questionnaire instruments were used to measure the independent and dependent variables of the study respectively. The gathered data was statistically analyzed with SPSS version 20. Out of the 405 questionnaires distributed, 365 copies were returned and 305 copies (90.12% response rate) were valid and used for analysis. The study revealed that bureaucratic culture was the most dominant culture type prevailing at public hospital in Addis Ababa, Ethiopia. The analysis of organizational commitment showed that the level of affective and normative commitment was low, whereas the level of continuance commitment was moderate. Finally, public hospitals in Addis Ababa are recommended to give more emphasis on improving the innovative and supportive culture instead of bureaucratic culture as the later showed no significant effect on employee commitment.Keywords: bureaucratic culture, organizational commitment, public hospitals.
