Field experiment was conducted to assess the effect of nitrogen and farmyard manure (FYM) on leaf content of pear cv. Punjab Beauty. The 15 treatments comprised of nitrogen levels i.e. 0, 200, 400, 600 and 800 g per plant and farmyard manure i.e. 30, 60 and 90 kg/plant. The nitrogen leaf content of pear increased with increasing doses of nitrogen whereas phosphorus and potassium leaf content decreased. The pear leaves nitrogen content was 2.43% with 800 g nitrogen/plant. The nitrogen, phosphorus, and potassium nutrient content of leaves increased with increasing doses of FYM. The maximum leaves nitrogen 2.41%, phosphorus 0.20% and potassium 1.37% nutrient content with application of 90 kg of manure/plant. The interaction between nitrogen and FYM is positive impact on leaves nutrient content. The nitrogen 2.51%, phosphorus 0.19% and potassium 1.35% was recorded with 600 g nitrogen and 90 kg/plant. Further, regression analysis revealed that leaf nitrogen content (R2 = 0.979) influenced the fruit yield and fruit weight significantly. It is concluded from this study that 600 g nitrogen along with 90 kg FYM was optimum doses for Japanese pear for better leaves nutrient status, higher fruit weight, and yield of pear fruit crop.

This study investigated the influence of ambient temperature on academic performance of a cohort of 259 students of Kashim Ibrahim College of Education, Maiduguri over a three year period i.e. from the year of their matriculation to completion. The students were randomly selected from four departments of the college. The achievements of these students (GPA) at the end of each semester examination that roughly coincided with hot and cool seasons were collected beginning from their matriculation year in 2010 through 2013 (graduation year). Additionally questionnaires instrument was used to gauge the perceptions of the students’ performance in the two seasons at the end of the final year. Student’s t – test statistic was used to compare the performance of students in the two semesters. Results generally showed significant differences between the two seasons in terms of students’ performance in the first and third years (p <0.001) while no significant differences could be established in the second year (p >0.001). Disaggregated data on the basis of departments however showed significant difference only with respect to the two science courses (Agriculture and Integrated Science) while the two humanities courses (Social Studies and English Language) showed no significant difference (p >0.001). Although most students preferred academic activities during cool season, chi squared test of the association between sex, place of origin and duration of stay in Maiduguri and performance did not show any significant difference (p >0.05). It was recommended that academic activities be staggered to emphasise early morning and evening activities during hot weather to improve teaching and learning. Other measures recommended include decongestion of classrooms, provision of adequate ventilation, the use of white colour paint in school buildings and improvement in electricity supply to schools.

Gamma radiation dose rate was measured at the base of 11 KV, 33 KV, 132 KV and 330 KV high tension lines (power lines) from different locations in Kaduna including Mando transmission sub-station using Radex 1503+ model. A total of about 187 measurements were taken and calculated. Radiation dose rate was also measured from a control site, an area that has no power line for comparison. Results show that the highest radiation dose rate from power lines within the city and the control site were about 1.46 mSv and 1.52 mSv respectively, which are greater than the ICRP guideline of 1mSv for public exposure by about 46% and 52% respectively. The results also show inconsistent relationship between the radiation dose rate and distance from the base of the power line. Results from the power sub-station was a little above that from the control site, about 0.84 mSv which comparing to ICRP guideline of 20 mSv for occupational exposure, the measured data is about 4.2% of ICRP guideline. Though the power lines show no significant evidence of emitting ionizing radiation, the high radiation dose rate (above the guidance level for the public), including the control site may probably result from beta radiation from 40K, a known beta radiation emitter constituent of fertilizer use in farming that is very common in the area, since Radex radiation meter also measures beta radiation.

As a result of the rapid changes in information and communication technology (ICT), the world has become a small village where people from all over the world connect with each other in dialogue and communication via the Internet.  Also, communications have become a daily routine activity due to the new globalization where companies and even universities become global residing cross countries’ borders. As a result, translation becomes a needed activity in this connected world. ICT made it possible to have a student in one country take a course or even a degree from a different country anytime anywhere easily. The resulted communication still needs a language as a means that helps the receiver understands the contents of the sent message. People need an automated translation application because human translators are hard to find all the times, and the human translations are very expensive comparing to the translations automated process.  Several types of research describe the electronic process of the Machine-Translation. In this paper, the authors are going to study some of these previous researches, and they will explore some of the needed tools for the Machine-Translation. This research is going to contribute to the Machine-Translation area by helping future researchers to have a summary for the Machine-Translation groups of research and to let lights on the importance of the translation mechanism.

The bio-chemical activity in eight sugarcane varieties was studied in a poly bag experiment at Agricultural Research Station, Basanthpur, Medak, India. The anti-oxidant enzyme activity in terms of superoxide dismutase and peroxidase activity in sugarcane genotypes increased upon exposure to moisture stress for 20 days at formative stage (120 DAP) and the maximum was found in the varieties Co 95020 and Co 87025 ranging from 109 to 122 and 20 to 21 eu/100 ml/gram fresh weight, respectively. The relative water content ranged from 10.92 to 37.72% among the varieties due to water stress with maximum reduction in Co 8014 (37.72%). Moisture stress at formative stage has also reduced the cane yield by 19.62 per cent as compared to irrigated treatment. The least reduction in cane yield was noticed in Co 87025 (11.76%) and Co 95020 (11.21%). The increase in anti-oxidant enzyme activity during stress was also found significant and positively correlated with relative water content and cane yield up to 78 and 63%, respectively.

Parental influence on the student’s mathematics interest development process cannot be neglected if achievement in mathematics is connected to the student’s’ interest in mathematics. The advances in research regarding parental association to their children interest in terms of achievement, attitude and beliefs proves that parental values and beliefs system shape the student’s values and performance. The study aims at exploring the effect of parent’s level of education, parent’s mathematics interest, as well as determining the role parental motivation play towards the student’s mathematics interest development. In addition, the study also determined the effect of student’s agent of motivation on student interest in mathematics. The study randomly selected 1,263 participants from ten randomly selected secondary schools in Ghana. Survey questionnaires were used to investigate parental involvement in student’s interest in mathematics. We used SPSS version 16 to generate all statistics and tables. The non- parametric Chi-square test of independence was used to investigate the effect of parental factors on students’ interest in mathematics. The findings suggest that students’ interest in mathematics is influenced by their parents’ educational background, parents’ interest in mathematics, and agent of student motivation but independent on parental motivation. The study concluded that parental involvement is very essential in the interest development process, and could improve performance when taken seriously.
