Adoption of Digital Learning Technology: An Empirical Analysis of the Determinants in Telecom Sector []

Technology has advanced significantly from the analogue period to the digital era. Digital Learning Technology (DLT) is a learning paradigm based on the use of ubiquitous latest technologies, by using smart devices. It can be described as a learning environment that is assisted in daily life by wireless networks, mobile, and embedded computers. It aims to offer content and interaction to students wherever they are, at any time. The learning process has advanced thanks to the technology revolution, which has also fundamentally altered how knowledge is shared and learned. At present, there exist other frameworks too, but they are centered towards different paradigms, and point of view pertaining to DLT with its emphasis on Telecommunication Sector has not been taken into consideration. As, existing frameworks are centered towards different environments hence there exists a need to add dimensions of Empowered Learner, Digital Citizen, Knowledge Curator, Innovative Designer, Computational Thinker and Creator, Communicator & Global Collaborator. These have not been integrated together in existing available research. The study will ascertain level of knowledge of DLT and examine factors which affect the adoption rate, use, and role of DLT in telecoms setups. The results of this research will help create a framework that, if used in any academic or learning setting in a technology-based firm.

Effect of Mass Recovery time on a Three-Bed Adsorption Chiller []

In this paper, the effect of mass recovery time on a three-bed adsorption chiller has been numerically studied. In the present numerical solution, the heat source temperature variation is taken from 50°C to 90°C along with coolant inlet temperature at 30°C and the chilled water inlet temperature at 14°C. The configuration of beds in the three-bed chiller with mass recovery were taken as uniform in size. The performances in terms of cooling capacity (CC) and coefficient of performance (COP) are compared with those of conventional three-bed without mass recovery scheme. Results show that three-bed adsorption chiller with mass recovery scheme provides more CC values than those provided by the three-bed system without mass recovery scheme while it provides better COP values for 85°C heat sources temperature.

The Effect of Grinding Process on Surfaces After Cutting Processes []

The paper is a review of the effect of the grinding process on surfaces after cutting. Grinding is a critical process in manufacturing because it increases the precision and durability of products. The review was based on evidence from published studies about the benefits and challenges of grinding. As a finishing process, grinding is applied to workpieces to improve accuracy, surface quality, texture, and value. Accuracy is critical for the machination of large and small parts while improvement of surface quality and texture helps to increase the functionality and efficiency of products. However, while grinding was linked to these benefits, some challenges were reported. The challenges were attributed to thermal damage resulting from the heat generated from the frictional resistance when the workpiece met the grinding wheel. The drawbacks of the process were oxidation burn, re-hardening burn, and residual stress. These challenges reduced the quality and functionality of workpieces. Key Words: Grinding, Oxidation Burn, Residual Stress, Re-Hardening Burn

The immune system comprises White Blood cells, antibodies, the lymphatic system, and more. Apart from just fighting off infections, the immune also remembers the microbe, which makes it easier for our body to fight it off the next time we are infected by the same microbe. As our immune system plays a crucial role in our lifestyle, it is important to understand what impacts the functioning of our immune system.

Optimization of Glucose Yield from Acid, Alkali and Microbial Hydrolysis of Agricultural Wastes. []

In this study, agricultural waste materials such as cassava, yam, and potato peels, as well as maize, millet, and sorghum brans, were used. These materials were ground into fine powder using a disc mill and sieved to ensure a consistent particle size. The resulting powders were labeled as cassava peel powder (CPP), yam peel powder (YPP), potato peel powder (PPP), maize bran powder (MaBP), millet bran powder (MiBP), and sorghum bran powder (SBP). Chemical hydrolysis of the samples was carried out using Sulphuric acid and Sodium hydroxide, and the effect determined by evaluating the percentage contents of lignin, hemicellulose and cellulose as well as glucose yields. The effect of microbial hydrolysis, using Bacillus amyloliquefaciens, was also investigated. Acid and alkali hydrolysis was performed using five different concentrations ranging from 0.01 M to 0.25 M. Optimization of microbial hydrolysis was carried out by varying pH values (5 to 9), substrate concentration (0.02% to 0.1%), temperature (30oC to 50oC) and duration of saccharification (over a period of 48 hours). Results of the acid hydrolysis indicated an increase in the lignin and cellulose contents of the samples with increasing acid concentration. Lignin contents ranged from 8.50% (in SBP) to 45.16% (in MaBP), cellulose ranged from 61.80% (in CPP) to 78.57% (in SBP). The hemicellulose contents, however, reduced during acid hydrolysis as acid concentration increased, from 21.88% (in PPP) to 10.71% (in SBP). Results of the alkali hydrolysis indicated a reduction in lignin, cellulose and hemicellulose contents of samples as concentration increased. For lignin values ranged from 16.08% (in PPP) to 9.10% (in SBP), cellulose values ranged from 36.89% (in SBP) to 20.27% (in MiBP), while hemicellulose values ranged from 16.40% (in CPP) to 10.16% (in PPP). Glucose yields for both acid and alkali hydrolysis increased with increasing concentrations of hydrolytic agents. In the microbial hydrolysis, the gravimetric results show a gradual increase in percentage lignin and cellulose contents, while hemicellulose did not show defined trend. The glucose yields increased with rise in incubation temperature, with higher yields between 35oC and 40oC. Glucose yields were higher at pH 7 than at acid or alkaline pH. Increase in substrate concentration improved glucose yields, with highest yields recorded in 1% substrate concentration. Glucose yields also increased with incubation time. Highest yield of 0.237 mg/ml was observed with CPP with substrate concentration of 1%, a starting pH 7, incubated at 35oC for 48 hours.

Flexural response of bolted lapped connections in multi-span cold formed steel purlins []

The In the last 50 years, cold-formed steel structural members such as Z-section purlins have been widely utilized in the metal building construction sector, e.g., pre-engineered buildings. The popularity of these products has risen dramatically in recent years because of their wide applications, low cost, excellent strength-to-weight ratios, and simplicity in fabrication. Plain Z-section purlins are the most common cold-formed steel purlins used for roof systems across the world. Two Z-section purlins are connected so that they function as continuous members of a pre-engineered building with a larger bay span. The purlins model was made with two spans. Dimension of each span was 8.250m c/c and the spacing between each row of purlin 1.170m c/c, while cleats are used to connect purlins with the supporting beam. For analysis of purlin model, SAP2000 Software was used and found the vertical deflection at intervals (i.e. 0.00mm, 3300mm, 3467mm, 4783mm & 8250mm) under applied loading of 4 increments sequentially. Parallel to the analytical work, an experimental test was also performed to understand the flexural rigidity behaviour of lapped connections over the internal support in multi-span. For experimental work, full-scale two-span purlins were used while the exterior ends were pinned connections while the interior was lapped connections, and the vertical deflections were measured at the same intervals mentioned above by using SOKIA Auto Level-B20, under applied loading at intervals of 4 increments. Comparisons were made between vertical deflections obtained from analysis using SAP2000 software, experiments, and code IBC-2009.
