The effects of weather factors on titrating acids accumulation in sweet cherry fruits
(2022-12-29)
During the fruit formation, the weather conditions have a decisive influence on the organic acids accumulation. In the context of global climate change, this issue has become new. The study of the titrated acids content in sweet cherry fruits was carried out for 12 years. Cherry fruits of three ripening groups were selected for the study. The average and strong correlation dependence between 11 weather factors and the titrated acids content for the sweet cherries varieties of early, middle, late ripening periods were ...

Effect of Cell Morphology on Flexural Behavior of Injection-Molded Microcellular Polycarbonate
(2022-05-19)
The quantitative study of the structure and properties relationship in cellular materials is mostly limited to cell diameter, cell density, skin layer thickness, and cell size distribution. In addition, the investigation of the morphology is generally carried out in two dimensions. Therefore, the
interrelation between morphological properties and mechanical characteristics of the foam structure has remained in an uncertain state. In this study, during the physical foaming process, a foam morphology is locally created ...

Hydrogen absorption of ultra-high strength aluminum-silicon coated 22MnB5 steels
(2022-12-30)
The hot forming process allows to produce safety-relevant structural components in the automotive industry with strengths of 1500 MPa and higher. Generally, high strengths make material sensitive to hydrogen embrittlement. The heat treatment in the hot forming process chain is a potential source of diffusible hydrogen for hot-dipped aluminum-silicon coated boron-manganese steels. In the present work, the influence of different process gases and furnace dwell times during the heat treatment was investigated. Humidified ...

Identification of socio-economic characteristics and farmers’ practices affecting rice (Oryza spp.) yields in Benin (West Africa)
(2022-12-28)
Rice (Oryza spp.) is one of the major staple foods in Benin. Benin has increased rice production through the expansion of cultivation area rather than increasing rice yields. To better understand the factors affecting rice yields, a thorough understanding of the current rice production system characteristics and constraints is required. The present study identifies socio-economic characteristics and farmers’ practices affecting rice yields and suggests improved cultivation practices in the sector. Data were collected ...

Income and price elasticities of animal food demand and welfare in Indonesian urban: an application of the LA-AIDS
(2022-12-30)
Protein consumption can be a measure of the welfare of society. Developed countries consume more protein than developing countries. This study analyzes the effect of rising prices and income on demand and welfare in urban Indonesia. The research data use the 2018 Household National Socio-Economic Survey (Susenas) data in household consumption and expenditure data collected by the Central Statistics Agency (BPS). The number of samples is 133,873 households. The demand systems approach uses the Almost Ideal Demand ...

Sustainable Eating Futures: A Case Study in Saudi Arabia
(2022-10-25)
Food systems are central to human societies. Developing sustainable, nutritious, and healthy food systems will be crucial to accomplishing sustainable development goals. The multifarious politics underlying food production, distributions as well as consumption are often ignored. The present paper analyses different factors affecting food consumption in the local population of Saudi Arabia and relates them to the supply chain. Different futuristic scenarios are discussed to develop sustainable food consumption practices ...

Microstructural and mechanical properties of AlSi10Mg: Hybrid welding of additively manufactured and cast parts
(2022-12-07)
Welding and joining of hybrid components consisting of additively manufactured (AM) parts and conventionally processed parts offer new opportunities in structural design. In the present study, AlSi10Mg specimens were fabricated using two different manufacturing processes, i.e., laser-based powder-bed fusion of metals (PBF-LB/M) and casting, and welded by means of friction stir welding (FSW). Material strength of dissimilar welded joints was found to be governed by the as-cast material, which is characterized by a ...

Additive Manufacturing of Binary Ni–Ti Shape Memory Alloys Using Electron Beam Powder Bed Fusion: Functional Reversibility Through Minor Alloy Modification and Carbide Formation
(2022-11-30)
Shape memory alloys (SMAs), such as Ni–Ti, are promising candidates for actuation and damping applications. Although processing of Ni–Ti bulk materials is challenging, well-established processing routes (i.e. casting, forging, wire drawing, laser cutting) enabled application in several niche applications, e.g. in the medical sector. Additive manufacturing, also referred to as 4D-printing in this case, is known to be highly interesting for the fabrication of SMAs in order to produce near-net-shaped actuators and ...

Electrochemical polarization behavior and superelastic properties of a Fe–Mn–Al–Ni–Cr shape memory alloy
(2022-10-22)
The present study investigates the corrosion behavior of a Fe–Mn–Al–Ni–Cr shape memory alloy in a 5.0 wt% NaCl solution in combination with the functional properties. In a single crystalline condition, the investigated alloy shows a superior superelastic response with a maximum recovery strain of 5.2%. Furthermore, the results of the potentiodynamic polarization and impedance spectroscopy show that the addition of chromium generally improves corrosion resistance by increasing the resistance to localized corrosion. ...

Consumers ’ perception of sustainable packaging in the food industry: An online experiment
(2022-01)
Consumers evaluate products and make purchasing decisions based on packaging and its sustainable aspects. This research investigated how different packages and their quality, eco-friendliness, expensiveness, and convenience affected consumers’ intentions to purchase. Our sample comprised 299 French consumers of muesli cereals. We conducted an online choice experiment to analyze and measure consumers’ perception of sustainable packaging, comparing three distinct experimental groups. Findings revealed that quality and ...
