Effect of Pre-sowing Treatments on Vegetative Growth and Production of Graftable Rootstocks in Mango

The present investigations “Studies on the effect of pre-sowing treatment and time of wedge grafting on production of saleable grafts in mango” were carried out in the nursery block of Fruit Science Department. The study was conducted using wild mangoes seeds. The seeds were divided in two equal halves, one half of seeds were sown with intact seed coat (K1) while, in other half the mango kernels were extracted (K2), both type of seeds were then soaked in 6 different chemicals of varying concentrations viz. C1- KNO3 @ 0.5%, C2- KNO3 @ 1%, C3- KNO3 @ 1.5%, C4- BA @ 50 ppm, C5- BA @ 100 ppm, C6- GA3 @ 100 ppm, C7- GA3 @ 200 ppm, C8- beejaaumrit @ 2%, C9- beejaaumrit @ 3%, C10- panchgavya @ 2%, C11- panchgavya @ 3% for 12 hours and C12- Control. The germination and vegetative parameters were observed. The results of study revealed that the e×tracted kernels pre-soaked with GA3 @ 100 ppm produced earliest germination, 50 % germination, high rate of germination, germination percentage, number of leaves, maximum leaf area, highest seedling vigour index, while, on pre-soaking extracted kernel with KNO3 @ 0.5% produced maximum seedling diameter. The Seedling raised from extracted kernels pre-soaked in KNO3 @ 0.5% (C1K2) attained graftable diameter within 210 days of sowing. The present investigation was conducted during 2019-2020 at the nursery block of College of Horticulture and Forestry, Neri Hamirpur (H.P) to study the effect of pre-sowing treatments on germination, growth and production of graft-able seedlings.

Web Portal for Student and Teacher Management

The aim is to make an online web portal for Computer Science Department, so that everyone can get information about department, students can easily communicate with teachers from anywhere. Teachers can easily communicate with students, and can keep records of every student easily and efficiently. The proposed system could be accessed from any corner of the world on net.

Large scale services for connecting and integrating hundreds of linked datasets

Michalis Mountantonakis is a Postdoctoral Researcher of the Information Systems Laboratory at FORTH-ICS (Greece) and a Visiting Lecturer in the Computer Science Department at University of Crete (CSD-UoC), Greece. He obtained his PhD degree from the CSD-UoC in 2020. His research interests fall in the areas of large-scale semantic data integration, linked data and semantic data management. The results of his research have been published in more than 20 research papers. For his dissertation, he awarded a) the prestigious SWSA Distinguished Dissertation Award 2020, which is given to the PhD dissertation from the previous year with the highest originality, significance, and impact in the area of semantic web, and b) the Maria Michael Manasaki Legacy's fellowship, which is awarded to the best graduate student of CSD-UoC, once a year. In his dissertation, supervised by Associate Professor Yannis Tzitzikas (Computer Science Department at University of Crete), Michalis Mountantonakis dealt with the problem of Linked Data Integration at large scale, which is a very big challenging problem. He factorized the integration process according to various dimensions, for better understanding the overall problem and for identifying the open challenges, and proposed novel indexes and algorithms for providing core services, which can be exploited for several tasks related to Data Integration, such as: for finding all the URIs and all the available information for an entity, for producing connectivity analytics, for discovering the most relevant datasets for a given task, for dataset enrichment, and many others.

Exploring Investigation of the Impact of Studying Statistics at Enhancing Mathematical Skills during Years of Faculty

Subject of statistics has always known as field related to mathematics and because statistics is commonly taught in schools as part of the mathematics curriculum, it is regarded as a mathematical. In Salahaddin University, entering to department of statistics is limited to students who graduated from science department at high school. Thus, we anticipating students with good knowledge in mathematical level. Students from all stages of the department were encouraged to participate in the exam and their scores were recorded. The objective of this study are to explore whether there is substantial difference between male and female as well as to discover whether the more higher stages enhance their mathematical level of knowledge. Normality test was done on the dataset and if failed to meet it, non-parametric test such as Mann-Whitney U and Kruskal-Wallis test at significant level 0.05.

THE EPISTEMIC ROLE OF DESIGN EDUCATION IN AN ENGINEERING SCIENCE DEPARTMENT

Design courses in engineering education provide the space in the curriculum to synthesizetheoretical and technical knowledge gained from coursework. As students gain new knowledge and acquire skillsets, there is a need to demonstrate how the learning connects to their professional actions. With practice and rehearsals, students realize the values and dispositionsthey need to possess to be deemed a disciplinary member. In this paper, through semi-structured interviews of six design instructors, we report what instructors think is the epistemic role of design courses in instilling disciplinary values in an Engineering Science program.
