Process Influences in the Combined Compacting and Back-Injection Process to Produce Back-Injected Self-Reinforced Composites (SRCs) – Analysis via Multiple Regression Modelling
(2021-11-21)
A new process to produce back-injected self-reinforced composites (SRCs) is presented. In contrast to other investigations on back-injection of SRCs, a process is presented which allows compacting and back injection of SRCs in one step where the SRCs are partly consolidated only via melt pressure inside the cavity. The mechanical properties of SRCs depend to a large extent on the process parameters of temperature and pressure during manufacture. These parameters are not yet known for back-injected areas. Sensors ...

Leveraging Biodiversity Action From Plural Values: Transformations of Governance Systems
(2021-06-04)
In this paper, we argue that leveraging plural values into action for biodiversity requires a focus on transforming the biodiversity governance system. We draw on Donella Meadows’ concept of Leverage Points, which outlines the “depth” of intervention in order to shift a system toward sustainability. Engaging with deep leverage points (system intent and goals) is argued to lead to greater transformation than engaging with shallow leverage points (system design and materials). We outline how embracing plural values of ...

Bridge over troubled water: managing compatibility and conflict among thought collectives in sustainability science
(2021-12-01)
Sustainability transformations call forth new forms and systems of knowledge across society. However, few tools and processes exist for promoting dialogue among different interests and normative stances in knowledge co-creation. In this article, we build on the notion of thought collectives to argue that understanding and moderating normative tensions are necessary if sustainability science is to provide successful solutions. Drawing on an analysis of the normative tensions between rival high-tech and low-tech thought ...

Using Moringa Oleifera Seed Cake and Compost as Organic Soil Amendments for Sustainable Agriculture in Valencia Orange Orchard
(2021-09-24)
This work was conducted during two consecutive seasons of 2016/2017 and 2017/2018 at the Experimental Research Station of National Research Centre at Nubaria, El Behiera governorate, Egypt. Twelve year old Valencia orange trees (Citrus sinensis L. Osbeck) budded on Volkamer lemon rootstock, grown in sandy soil under drip irrigation system as plant materials to study the effect of six organic soil amendment treatments on soil hydrophysical properties, soil water retention, soil water movement, plant nutrient contents, ...

Food Enhancers Usage in Home Food Preparation among the Young Working Women in Malaysia: A Qualitative Study
(2021-11-29)
This paper explores the usage of food enhancers in food preparation among young working women in Malaysia. In this qualitative study, the study informants were drafted using purposive snowball strategy to take part in a semi-structured interview. The data were recorded and analysed accordingly to the research aims. Majority of the informants claimed that they used food enhancer to enhance the flavour and taste of the food while reducing cooking time, minimise preparation processes and time spent in the kitchen. As ...

Determination of fat, salt and sodium contents of selected fast food items available for sale in Colombo city, Sri Lanka: An approach to colour coding of fast foods
(2021-11-29)
Fast food has become a popular trend among Sri Lankan consumers. However, the nutritional facts of these food items that aid consumer awareness are scantly found in Sri Lanka. This study aimed to examine fat, salt and sodium contents of selected fast food types sold in Colombo city. A questionnaire-based survey was conducted to identify the fast food consumption patterns of the target population. Fat, salt and sodium contents of highly preferred fast food types selected based on the survey, namely; Chinese fish roll ...

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 ...

Effect of Crystallographic Orientation and Grain Boundaries on Martensitic Transformation and Superelastic Response of Oligocrystalline Fe–Mn–Al–Ni Shape Memory Alloys
(2021-07-26)
In situ tensile tests employing digital image correlation were conducted to study the martensitic transformation of oligocrystalline Fe–Mn–Al–Ni shape memory alloys in depth. The influence of different grain orientations, i.e., near-〈001〉 and near-〈101〉, as well as the influence of different grain boundary misorientations are in focus of the present work. The results reveal that the reversibility of the martensite strongly depends on the type of martensitic evolving, i.e., twinned or detwinned. Furthermore, it is ...
