The influence of electric loading on crack paths in ferroelectrics
(2020-05-30)
Ferroelectric materials are widely used in our daily life and many advanced industrial products. The understanding of their fracture behavior has been in the focus of research for decades, since the success of their application requires reliability and durability. For ferroelectric fracture behavior, different fracture criteria have been proposed and the influence of various mechanical-electric loading combinations on crack propagation have been investigated. However, the crack path and the deflection of crack ...

A systematic literature review exploring uncertainty management and sustainability outcomes in circular supply chains
(2021)
The circular economy (CE) has inspired the emergence of circular supply chains (CSCs) to reduce the environmental impacts of linear production systems. However, the transition to CSCs faces numerous challenges and uncertainties, which in turn impact the sustainability performance of CSCs. Following a systematic review process, this paper aims to identify the uncertainties that CSCs entail and the uncertainty management strategies which can be used to mitigate them to enhance their sustainability performance. A ...

Implementing Distributed Practice in Statistics Courses: Benefits for Retention and Transfer
(2020-11-18)
The present study investigated the effect of distributed versus crammed practice before a course deadline on the retention and transfer of knowledge, and whether learner characteristics moderate the effect. In Experiment 1, only 41% (N = 38) of the initially enrolled students worked the voluntary but recommended practice tasks. Moreover, markedly fewer students did so in the distributed condition (12%) than the crammed practice condition (29%). In Experiment 2, working the practice tasks was mandatory and more students ...

Influencing factors of adopting solar irrigation technology and its impact on farmers’ livelihood. A case study in Bangladesh
(2021-12-15)
Sustainable irrigation access is considered critical for agricultural growth in Bangladesh, which vindicates the food and livelihood security. Solar powered irrigation system had emerged as promising technology to make sustainable irrigation in Bangladesh. This study examines the factors affecting the adoption of solar powered irrigation system and the impact of this technology on livelihood of farmer. To conduct this analysis, data were collected from Meherpur district of Bangladesh. Simple random sampling technique ...

Food rescue and donation in socioenvironmental policies on tackling food loss and waste: a systematic review
(2021-12-20)
In recent years, there has been an increasing concern among governments about food loss and waste – FL&W and, in this context, the food rescue and donation – FR&D has emerged in the scenario of socioenvironmental policies as a strategic factor for FL&W reduction. Despite FR&D have potential to establish a “win-win” arrangement between the spheres of waste management and demands of food security, it still has been perceived as a less attractive alternative than forwarding the surplus food to the waste treatment system. ...

Decontamination of Pineapple (Ananas comosus) juice using Ozone as a Non-thermal Sterilization method
(2021-12-15)
Ozone is a non thermal preservation technology used for enhancing shelf life and the safety of the food products. The objective of this study was to evaluate the effect of gaseous ozone on microbial decontamination and on some physicochemical characteristics (soluble solids content, pH, titratable acidity and color), bioactive compounds and total antioxidant activity of Pineapple juice. Ozone treatments were applied for Pineapple juice at 4 different exposure times as 15 mins, 30 mins, 45 mins and 60 mins at 250C and ...

Antioxidant activity of a mixture of water-soluble tempeh extract with whey powder that has undergone a Maillard reaction
(2021-12-20)
High amino acid content in tempeh and lactose in whey powder can be combined to perform Maillard reaction. So, it can be used to produce functional food products. This is caused by the formation of Amadori and melanoidin as water-soluble compounds which are reported to have high antioxidant capacity and produce a preferred flavor. The general objective of the study was to obtain an optimum process condition in a mixture of water soluble tempeh extract and whey powder with the highest antioxidant capacity (100 mL). ...

Preliminary assesment on drought tolerant oil palm in semi-arid area
(2021-12-15)
The evaluation of oil palm growth performance and their corresponding effect on drought very crucial in selection of proper parent’s tree. The parent palm that showed drought tolerance and have less effect on oil yield is important for optimisation semi-arid lands usage in future. The Split plot with two replications in a randomized complete block design (RCBD) were conducted and mixed stand with an adjacent control plot. All 19 progenies was evaluated and interaction effects are estimated using split plots analysis. ...

Caught in the Act: Predicting Cheating in Unproctored Knowledge Assessment
(2020-05-20)
Cheating is a serious threat in unproctored ability assessment, irrespective of countermeasures taken, anticipated consequences (high vs. low stakes), and test modality (paper-pencil vs. computer-based). In the present study, we examined the power of (a) self-report-based indicators (i.e., Honesty-Humility and Overclaiming scales), (b) test data (i.e., performance with extremely difficult items), and (c) para data (i.e., reaction times, switching between browser tabs) to predict participants’ cheating behavior. To ...

The effects of grain storage technologies on maize marketing behaviour of smallholder farmers in Zimbabwe
(2020-01-13)
This study investigated the effects of grain storage practices on smallholder farmers’ maize marketing behaviour using primary data collected from 413 random households in Makoni and Shamva Districts of Zimbabwe. The data was analysed using the ordered probit model and the study results revealed that storage practices had significant effects on the maize marketing behaviour of smallholder farmers. Storage using insecticide and traditional granary increased the chances of farmers to become net sellers of maize. Using ...
