An investigation of the aspects affecting non-Muslim customers’ purchase intention of halal food products in Jakarta, Indonesia
(2021-05-25)
The international trade market of halal food products is huge and has become a fast-growing segment. People that consume food and beverage will also consider if it is good for health, well-being, nutrition, and physical fitness. Nowadays, halal products are requested by Muslim and non-Muslim customers due to safety and quality concern. Even though several studies have been conducted for Muslim customers, but there is a lack of data by foregoing studies which exploring non-Muslim customers about their intention in ...

On the Impact of Build Envelope Sizes on E-PBF Processed Pure Iron
(2021-11-17)
In additive manufacturing, the thermal history of a part determines its final microstructural and mechanical properties. The factors leading to a specific temperature profile are diverse. For the integrity of a parameter setting established, periphery variations must also be considered. In the present study, iron was processed by electron beam powder bed fusion. Parts realized by two process runs featuring different build plate sizes were analyzed. It is shown that the process temperature differs significantly, ...

On the Microstructural and Cyclic Mechanical Properties of Pure Iron Processed by Electron Beam Melting
(2021-03-10)
Additive manufacturing (AM) processes such as electron beam melting (EBM) are characterized by unprecedented design freedom. Topology optimization and design of the microstructure of metallic materials are enabled by rapid progress in this field. The latter is of highest importance as many applications demand appropriate mechanical as well as functional material properties. For instance, biodegradable implants have to meet mechanical properties of human bone and at the same time guarantee adequate cytocompatibility ...

Nutrient and oil profile of Escamol, an edible larva of ants (Liometopum apiculatum Mayr)
(2021-05-25)
The objective of this study was to evaluate proximal chemical analysis, oil and fatty acids in escamol dehydrated and butter-fried that are commercially available in Mexico. In order to measure the escamol and oil quality, a chemical analysis were performed. The identification fatty acids was by refractive index. The proximal chemical analysis results in escamol fresh and deshydrated indicated that moisture (56.00-1.89 %), protein (15.30-34.78 %), lipids (20.05-45.57 %), ash (1.91-4.35 %) and carbohydrates (6.73-13.41 ...

CuCrZr processed by laser powder bed fusion — Processability and influence of heat treatment on electrical conductivity, microstructure and mechanical properties
(2021-06-16)
CuCrZr parts were fabricated by laser beam powder bed fusion (LB-PBF) technique and subjected to different heat treatments. As a result, four different conditions were considered for further investigations, that is, the as-built condition, conditions of maximum hardness (MH) and maximum electrical conductivity (MC), and a condition representing a compromise between hardness and conductivity (H&C). Microstructural evolution and performance under monotonic and cyclic loading were studied. Fracture surfaces revealed ...

Trust and the clean food imaginaries: an analysis of a short food supply chain from Romania
(2021-05-25)
As concerns about food safety and environmental issues gain more attention in the public eye, organic labels are growing in popularity, being presented as the solution for a more sustainable and conscious food system. Yet, organic certificates did not manage to actively change the food system but merely created a niche to be exploited, thus many of the environmental-friendly practices being co-opted by corporations without addressing the larger issues of concern. This paper looks at how small producers, who are ...

Thermal Stability of Residual Stresses in Differently Deep Rolled Surface Layers of Steel SAE 1045
(2021-05-07)
The stability of compressive residual stresses generated by deep rolling plays a decisive role on the fatigue behavior of specimens and components, respectively. In this regard, deep rolling at elevated temperature has proven to be very effective in stabilizing residual stresses when fatigue analysis is conducted at ambient temperature. However, since residual stresses can be affected not only by plastic deformation but also when thermal energy is provided, it is necessary to analyze the influence of temperature and ...

Finding alternatives: Canadian attitudes towards novel foods in support of sustainable agriculture
(2021-09-29)
Global agriculture and farming practices account for roughly a quarter of total atmospheric emissions. Protein agricultural is especially prone to green-house gas emissions. There is a need to find alternatives, both in the form of protein and sustainable practices in providing alternative protein sources. However, sustainable agricultural practices must consider consumer behaviour and attitude towards switching protein sources. In this study, we carried out a survey of 993 Canadians in order to better understand the ...

Additive Manufacturing of Compositionally-Graded AISI 316L to CoCrMo Structures by Directed Energy Deposition
(2021-08-30)
In the present study, compositionally-graded structures of AISI 316L and CoCrMo alloy are manufactured by powder-based laser-beam directed energy deposition (DED-LB). Through a process-integrated adjustment of powder flow, in situ alloying of the two materials becomes feasible. Thus, a sharp and a smooth transition with a mixture of both alloys can be realized. In order to investigate the phase formation during in situ alloying, a simulation approach considering equilibrium calculations is employed. The findings ...

Reasons for consuming rasi as a staple food for the Cireundeu indigenous people: a qualitative study
(2021-09-29)
Rasi (made from cassava) are used as staple food by the Cireundeu indigenous people. This food culture is considered different from the food culture of Indonesian people who generally make rice as their staple food. Therefore, this study aimed to show the reasons Cireundeu indigenous people consume rasi as their staple food. This qualitative research was conducted in Cireundeu Village, Cimahi City, West Java Province, Indonesia. Data was collected from the Cireundeu indigenous people through in-depth interviews and ...
