Extension of Shelf Life of Raw Milk in Transit by Use of Lactoferrin and Lysozyme

Cathrine L. Watama, Wishmore Gwala, Felix M. Mujuru and Raphael Kwiri · March 2022 · pp. 01-06

The aim of the study was to extend the shelf life of raw milk in transit by use of lysozyme and lactoferrin. The effects of temperature, lysozyme concentration and lactoferrin concentration on milk in transit were evaluated by measuring pH, titratable acidity and methylene blue reduction time for eight hours. From the screening tests the Pareto plots indicated lysozyme concentration and lactoferrin concentration as factors of high influence. Further experiments were carried out focusing on the two factors to determine the optimum concentrations of lysozyme and lactoferrin to maintain a constant pH and titratable acidity for 8hours. A 3D Response Surface Methodology (RSM) was used to graphically map and optimise conditions. Optimum conditions were found to be 0.5g/l and 4g/l of lactoferrin and lysozyme and lactoferrin respectively, to maintain pH at 6.7 – 6.9, titratable acidity at 0.12 and methylene blue reduction time at 10.25 hours.615minutes.

Organizations are increasingly appreciating the importance of performance appraisal as a veritable tool for promoting employee growth and development, as well as enhancing productivity. To achieve this, organizations require a comprehensive and routine workforce performance appraisal, to enable it position the right skilled manpower for productivity attainment, improvement and sustainability. Descriptive research design was adopted for this study, where primary and secondary data garnered from 500 level results from five consecutive academic sessions, were used to assess teaching performance and service delivery of lecturers, within the department of a University, South East Nigeria. Results showed the student scores of 50 marks and above in 500 level courses, were used to deduce the overall performances of lecturers (79.76, 53.37, 61.16, 73.33, 59.13, 72.73, 66.12, 79.60, 83.49, 76.85, 87.50, 71.96, 84.00, 88.91, 75.86, 76.48, 72.41, 80.90, 71.93) based on course participation and students’ percentage performances in taught courses.

Implementation of Robotic Process Automation Rpa in Education domain

Dr. Prakash K R, Nidish S · March 2022 · pp. 14-18

Automation is the future for organizational processes. Robotic Process Automation (RPA) is the solution for software automation in various domains like Supply chain Finance, IT and accounting, and so on. In this paper we propose RPA solution for education domain. This paper shows the automation process for result analysis of student’s examination results. The automation process takes the university result in pdf form as the input. We performed automation on this input file using Automation anywhere tool. Our result shows that all the work is error free. Also, time required for this analysis is around 94.44% less as compared to manual analysis by human.

Assessment of Suitability of Coating Systems for Subsea Systems

Franklin Okoro; Precious Chisom Jumbo-Egwurugwu · March 2022 · pp. 19-28

A comprehension of the variables that assist with the actualization of good adhesion is of vast scientific and technological significance in order to gain control over the phenomenon of adhesion. To improve protection, operators should commence with the critical analysis of the materials to be deployed and their suitability for the site/field specific conditions. Till date, there are relatively few reported studies relating to coating functional chemistry, mechanical properties and performance. This paper thus evaluated in-depth, the different types of coating materials with respect to their suitability for subsea operations and identified the best practices to expand the life of coatings, and coated structures. The assessment of the economic and technical problems of coating materials, their application, and their service behavior for subsea/deepwater operations have been conducted using the Technique for Order Preference by Similarity to Ideal Solution (TOPSIS). From the TOPSIS analysis, the best coating material considering the several criteria including: durability, resistance to stress, strength, adhesion, ductility, compatibility with cathodic protection and cost is Organic Coating which scored 0.653 followed by Nickel Alloy, with a value of 0.623 and the third best is Non-Ferrous Alloys.

Impact of Stakeholders on the Success of Project Cost Management in Construction Industry

Okeagu Fredrick Nnaemeka, Akintona Ezekiel Oluwadamilare, Nnamani Blessing · March 2022 · pp. 29-37

The construction industry is all important and unavoidable to the economic development of most nations in the world, stakeholders as an individual or a group of individuals who are influenced by or able to influence a project. Project cost management is a method that uses technology to measure cost and productivity through the full life-cycle of enterprise level projects. In Nigeria construction industry, the impact of stakeholders on the success of project cost management is not well understood in creating greater awareness of the value that stakeholders provide for projects. The result of this is lack of proper build team with the right skills of project cost management leading to failure of projects. This study assesses the impact of stakeholders on the success of project cost management. A quantitative approach was adopted for this study with a well-structured questionnaire. The tools employed for data analysis were mean item score and relative importance index. The study finds out that strong relationship of stakeholders is necessary for project cost management success, since a project can be considered a temporary organization of stakeholders pursuing an aim together. It was therefore recommended that there should be an effective awareness of stakeholders on the success of project cost management.

Improving Crimson Seedless grape quality

El Shaima M. El Botaty · March 2022 · pp. 44-49

The present study was executed at Behaira Governorate, Egypt during two consecutive seasons 2019 and 2020 on Crimson Seedless grape which is still ranking well among favorable cultivars in Egypt thus it’s worthy to raise its quality; definitely the coloration. For this purpose, ethephon and ethanol at various combinations were sprayed on clusters at two stages; pre veraison (a week earlier) and at veraison to determine the optimum treatment. Results show that the pre veraison sprays did not affect coloration or even enhanced berries physical or chemical characteristics so it was ignored later. As for veraison stage sprays, the physical characteristics except for berry firmness did not influenced by different treatments; however, the high concentrations reduced berries adherence force (AF). Regarding chemical characteristics, soluble solids content (SSC) and anthocyanin content were significantly affected by the treatments. The best results of the study characteristics such as; SSC, SSC/acid ratio, firmness and anthocyanin content were gained from combining ethephon and ethanol sprays at veraison stage. Whereas, treatments that contains either solely ethephon or ethanol, as well the highest concentrations combination (500 ppm ethephon +400 ml L-1 ethanol), have recorded lower values for almost studied characteristics. At the end, presence of ethanol at a moderate dose of 200 ml L-1 in the formula boost 250 ppm of ethephon role in enhancing berries physical and chemical characteristics especially coloration.
