Agripreneurial drive among women shea butter processors in Kwara State, Nigeria: the motivating factors and efficiency
(2022-10-12)
This study examined agricultural entrepreneurship among women shea butter processors in Kwara State Nigeria. It assessed their motivation factors, level of efficiencies, determinants of output and challenges faced in the entrepreneurial drive by the women. Primary data, collected using a semi-structured questionnaire, were collected from randomly selected 120 shea butter women processors. The data obtained were analysed with descriptive statistics, index ranking and the stochastic frontier function. The results showed ...

Taste masking in vegan food processing with natural substitutes
(2022-12-29)
Climate change, sustainability issues, increased risks of meat diet on both ecology and human health cause changes in the eating habits of individuals. Plant-based foods supply protein sources with health-promoting compounds. The bitterness of plant-based foods is a challenge for both food manufacturers and consumers. So far, artificial taste blockers, salt, sugar, and fat have been applied to mask the bitterness of plant-based products. However, people are conscious of "clean labelling " and "natural " ingredients ...

The potential of cabbage waste extract as a bio-stimulant for enhancing growth, biochemical constituents, and oil quality of thyme (Thymus vulgaris)
(2022-12-29)
Thyme (Thymus vulgaris L.) is an important cultural aromatic plant, whose herb and essential oils (EOs) have been used in many industrial and medicinal applications. Herb and EO yields are often negatively influenced by various factors, so it is important to keep finding new growing procedures that increase the quantitative content of herbs and EOs. Therefore, this paper is focused on the effects of applying cabbage extract (CE) at different concentrations on morphological parameters, mineral contents, total ...

Physiological response of some canola genotypes to proline concentration under saltwater irrigation conditions
(2022-12-29)
A pot experiment was conducted in split-split plot design with four replications to study proline foliar application with 0, 50, and 100 ppm and four canola genotypes cultivated under irrigation of tap water and salinity irrigation water at 4500 ppm and their interactive effects on growth characters, yield, and yield components and some chemical composition of the canola plants. Results indicated that a higher salinity level at 4500 ppm reduced growth, photosynthetic pigments, yield, and yield attributes as well as ...

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 ...

Characterisation of the lactation curve of Gyr and Sardo Negro cattle
(2023-07)
The objectives were to characterize the lactation curves (LC) of tropical Gyr and Sardo Negro (SN) cattle from Mexico for the design of breeding and management programs for these breeds. A total of 3561 records of 504 lactations and 3927 records of 449 lactations were used for Gyr and SN, respectively. Three lactation lengths (LL) were evaluated, namely 240 (240d), 270 (270d), and 300 (300d) days, with five non-linear models (NLM): Wood, Wiltmink, Cobby, Brody, and Sikka. Milk production was obtained at the beginning ...

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 ...

Mechanics of colloidal supraparticles under compression
(2021-10-13)
Colloidal supraparticles are finite, spherical assemblies of many primary particles. To take advantage of their emergent functionalities, such supraparticles must retain their structural integrity. Here, we investigate their size-dependent mechanical properties via nanoindentation. We find that the deformation resistance inversely scales with the primary particle diameter, while the work of deformation is dependent on the supraparticle diameter. We adopt the Griffith theory to such particulate systems to provide a ...

On data-driven nonlinear uncertainty modeling: Methods and application for control-oriented surface condition prediction in hard turning
(2020-10-16)
In this article, two data-driven modeling approaches are investigated, which allow an explicit modeling of uncertainty. For this purpose, parametric Takagi-Sugeno multi-models with bounded-error parameter estimation and nonparametric Gaussian process regression are applied and compared. These models can for instance be used for robust model-based control design. As an application, the prediction of residual stresses during hard turning depending on the machining parameters and the initial hardness is considered.

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 ...
