From Individual Guides to a more diverse group and from varied expertise/domains to many podia of massive open online courses (MOOCs) now are most commonly readily available to access. Some of them even recommend pre-courses if required before commencing with the MOOC. Although India as a developing country leads involvement in MOOCs in Asia, some factors that could challenge the feasibility of MOOCs in India could include: the traditional mindset of examination, habit of attending classes for records, network, access to hardware due to economic constraints, diversity of languages, the habit of memory-based learning, low involvement in self/research-based learning/skill-based learning, ethnicity, the credibility of employability quotient after MOOC, (Rai & Chunrao) only collecting, storing data but also reading, lack of guidance on the utility of material, increased interest in Audio - Visual and ppt rather than reading, lack of face to face learning atmosphere, lack of hands-on experience, etc. However, research studies indicate that even where the resources were present, the willingness to learn using MOOCs was negligible. This study is based on primary data collected via random sampling method from 150 respondents [students and faculties]. The literature reviews help to understand that there have been studies in past but not much on the current crisis of pandemic. Thus, such a study would help to examine the student engagement on these diversifies MOOC platforms. This study is explorative in nature, which outcomes demonstrating challenges and probable solutions to the student engagement on MOOC platforms in Universities. [ABSTRACT FROM AUTHOR]

The Almajiri system over the years has been linked indirectly with radicalization, unemployment and other social vices in Nigeria. This negates the initial ideals of the system as introduced a long time ago. This study focused on harnessing the potentials of Almajiri cohorts for entrepreneurship development. The study was conducted in two states in the northern part of Nigeria using focus group discussion. The findings reveal that the Almajiri system is undesirable as majority of discussants were tired of the system. The findings also show that a lot of the cohorts have entrepreneurship potentials in them. Therefore, the study recommends that government of states involved should make concerted efforts to equip the cohorts with entrepreneurship skills and values in order to harness entrepreneurship potentials in them.

• Tannins are important natural bioactive compounds found them in different forms. • Tannins are categorized into two types, i.e., condensed and hydrolyzable tannins; the sources of tannins are mainly barks, leaves, seeds and stems. However, tannins are also available in foodstuffs, i.e., tea, grape etc. • Condensed tannins are the most dominant one in the world market. • Wide range of solvents, i.e., water, methanol, ethanol, acetone and ionic liquids, and technologies, i.e., water, pressurized hot water, gamma assisted, infrared assisted and ultrasonic extraction are used for extracting tannins. • Tannins have many different applications largely in tanning industry, but they have some other advanced applications, such as, 3D printing, food supplement, medicines. Tannins are found in most of the species throughout the plant kingdom, where their functions are to protect the plant against predation and might help in regulating the plant growth. There are two major groups of tannins, i.e., hydrolyzable and condensed tannins. The tannins are being used as important and effective chemicals for the tanning of animal hides in the leather processing industry since the beginning of the industry. Additionally, the tannins have been using as mineral absorption and protein precipitation purposes since 1960s. These are also used for iron gall ink production, adhesive production in wood-based industry, anti-corrosive chemical production, uranium recovering chemical from seawater, and removal of mercury and methylmercury from solution. Presently, tannins are considering as bioactive compound in nutrition science. It has also been considered for advanced applications, i.e., 3D printing and biomedical devices. The application of tannins as medicine is another new dimension in medical science. This paper outlines the general information about tannins followed by their extraction process. The utilization of tannins has also been presented in a broader scale. Depending on all these information, the article also describes the impending utilization of tannins for ensuring high-sustainability and better environmental performance. [ABSTRACT FROM AUTHOR]

Favorable geographical position of municipality of Trstenik, which is located in a fertile valley of the West Morava river, would enable the local people to deal with rural tourism which lacks attention despite potentially positive effects which would be created due to its development. The primary aim of this research paper was the insight into the potentials of the municipality, which would contribute to a rural tourism development. The research was performed during the period from July 20 to September 2 of 2017 on a sample of 138 respondents. For the research purposes the following methods were available: quantitative approach by questioning public opinion via questionnaires close-ended and anonymous type, method of analysis, method of sample, as well as method of description. The results of the research showed the following: the territory of this municipality possesses potential for rural tourism development despite deficiency of accommodation facilities and insufficient motivation of the local people to deal with tourism, whereas social networks could contribute to its promotion and development. The limit of the research paper is reflected in a small extent of the target group of respondents, which leaves the possibility for widening of research outside the boundaries of the territory of this municipality.

The inversion symmetry of the components of the displacement vector and stress tensor in the solution of the first boundary-value problem of elasticity for a half-space is studied. The case where one component of loading on the half-space boundary has inversion symmetry and the other two components are equal to zero is considered. Inversion symmetry is also studied for the mixed problem where normal forces act and tangential forces are equal to zero one part of the half-space boundary, while the conditions of smooth contact are prescribed on the other part, and the problem of the torsion of an elastic half-space with tangential stresses given on its boundary.

The study was aimed at identifying the potentials of and barriers to the Smart School Project (SSP). Through the use of a mixed methods design, data were garnered from 746 school teachers, principals, and information technology experts, semi-structured interviews with 21 key informants and two researcher-designed questionnaires on the potentials of and barriers to SSP. The qualitative data were analyzed using three-stage coding and quantitative data were analyzed using exploratory factor analysis. The findings from the three data collection tools indicate 8 potentials and 9 barriers. SSP potentials include improving teachers', principals', and students' knowledge, skills and attitudes toward using information and communication technology (ICT), access to quality e-content, increasing school facilities, potentials available in the social environment, developing curriculum beyond schools, student participation in the learning process, enhancing school and parent relationship, and social supports and enacted laws. Further, SSP development barriers are comprised of 9 themes including teachers', principals' and students' lack of access to ICT and using it, vagueness in policies, missions, and goals of ICT integration into school curriculum, lack of support system and supervision, lack of specialized training for principals and teachers, barriers concerned with the nature of ICT, incompatibility of curriculum structure with ICT, structural and organizational barriers, cultural conditions and barriers, and lack of space and equipment.

Multi material design (mmd) represents the ideal compromise for the automotive lightweight design of the future with its capability of weight-reduced components at acceptable costs and practicability in large-scale production. At present, there are only limited selection strategies available for the goal-oriented identification of potential multi material areas in the vehicle. In order to develop a selection strategy for potential areas of application of the design method, the properties and conversion factors of existing components in hybrid construction methods from the automotive industry and research were investigated. In this contribution, the relevant influencing factors from component design, material selection, production and joining technology as well as cost planning are identified and their interaction is investigated. Based on a Pareto-Analysis in combination with the evaluation of a component study, significant effects could be identified regarding structural automotive components in mmd. The identified effects and their interaction are classified into a network of dependent variables. The "Network of mmd potentials" serves as a result of this contribution the basis for the development of an regression model for the indication of the feasibility of components in mmd.

As opposed to traditional laboratory testing, Molecular Dynamics (MD) offers an atomistic scale method to estimate the mechanical properties of metals. However, there is limited literature that shows the effect of interatomic potentials when determining mechanical properties. Hence, the present research was conducted to investigate the accuracy of various interatomic potentials in estimating mechanical properties of aluminium. Several types of potentials, including Embedded Atom Method (EAM), Modified EAM (MEAM) and Reactive Force Field (ReaxFF) were compared with available experimental data for pure aluminium to determine the most accurate interatomic potential. A uniaxial tensile test was performed at room temperature using MD simulations for nanoscale aluminium. Results demonstrated that those potentials parameterised with elastic constants at physically realisable temperatures were consistently more accurate. Overall, the Mishin et al. EAM potential was the most accurate when compared to single-crystal experimental values. Regardless of the potential type, the error was significantly higher for those potentials that did not consider elastic constants during development. In brief, the application of the interatomic potentials to estimate mechanical properties of a nanoscale aluminium was investigated. [ABSTRACT FROM AUTHOR]

We consider a class of Lévy-type processes derived via a Doob transform from Lévy processes conditioned by a control function called potential. These ground state transformed processes (also called P (ϕ) 1 -processes) have position-dependent and generally unbounded components, with stationary distributions given by the ground states of the Lévy generators perturbed by the potential. We derive precise upper envelopes for the almost sure long-time behavior of these ground state-transformed Lévy processes, characterized through escape rates and integral tests. We also highlight the role of the parameters by specific examples. [ABSTRACT FROM AUTHOR]

Tiger nut flour extracted from (black, brown and yellow) cultivars using attrition milling process was investigated. Tiger nut flours labeled Ab, Bb and Cy for black, brown and yellow cultivars were produced respectively. Proximate composition, mineral elements contents, functional properties of the tiger nut flours were determined. There was significant (p<0.05) difference between the moisture, ash, crude fat, crude fiber, crude protein and carbohydrate content of the flour samples which ranged 4.77 - 4.99%, 1.95 - 2.05%, (5.62 - 8.16%, 19.03 - 22.06%, 5.62 - 6.23%, 58.94 - 62.94% respectively. The least and the most moisture content of tiger nut were related to brown color (4.47%) and black color (4.99%) respectively. Flour crude protein value from brown Bb colored tiger nut flour 6.23% was higher than the black 6.28%. There was also significance (p<0.05) differences in the bulk density, water and oil absorption capacity and foam capacity which ranged from (0.76 - 0.79) g/ml, (1.76 - 1.79) ml/g, (1.43 - 1.79) ml/g, (4.72 - 9.9.0) % among cultivars; However, flour from brown color had better swell ability index and water absorption capacity. The flours from black color sample indicated high values in oil absorption and foaming capacities. There were no significant (p<0.05) difference in the swelling index of the flour samples which ranged between 2.22 - 2.57 g/ml. The mineral content of the tiger nut flours differed (p<0.05) significantly. Flour from black color tiger nut had excellent mineralization, Zn (2.14), Ca (93.75), P (10.14), K (121.95), Na (105.6) and Fe (4.04). This work revealed that tiger nut flour is a potential source of food ingredient for supplementation, in particular, local cereal food for all age groups and could be an excellent source of raw material for our growing functional food industries.
