On the Reliability of Automated Analysis of Fracture Surfaces Using a Novel Computer Vision-Based Tool
(2023-08-05)
Fracture surface analysis is of utmost importance with respect to structural integrity of metallic materials. This especially holds true for additively manufactured materials. Despite an increasing trend of automatization of testing methods, the analysis and classification of fatigue fracture surface images is commonly done manually by experts. Although this leads to correct results in most cases, it has several disadvantages, e.g., the need of a huge knowledge base to interpret images correctly. In present work, an ...

Cyclic Superelastic Behavior of Iron-Based Fe-Ni-Co-Al-Ti-Nb Shape Memory Alloy
(2023-01-03)
Iron-based shape memory alloys came into focus as promising candidate materials for large-scale structural applications owing to their cost-efficiency. In the present work, the superelastic properties of a recently introduced Fe-Ni-Co-Al-Ti-Nb shape memory alloy are investigated. For 〈001〉-oriented single-crystalline material in aged condition (650 °C/6 h), an incremental strain test reveals excellent superelasticity at −130 °C with fully reversible strains up to about 6%. Under cycling loading at different test ...

Continuous Feature Networks: A Novel Method to Process Irregularly and Inconsistently Sampled Data With Position-Dependent Features
(2023-12-30)
Continuous Kernels have been a recent development in convolutional neural networks. Such kernels are used to process data sampled at different resolutions as well as irregularly and inconsistently sampled data. Convolutional neural networks have the property of translational invariance (e.g., features are detected regardless of their position in the measurement domain), which is unsuitable if the position of detected features is relevant for the prediction task. However, the capabilities of continuous kernels to ...

Partial purification of tannase enzyme produced by Bacillus licheniformis isolated from local soils
(2023-12-28)
Tannase is an enzyme that causes hydrolysis of a group of tannins (gallo-tannins) to gallic acid and glucose. This enzyme is of importance due to its numerous applications in many fields, such as in the food industry by enhancing tea and coffee flavour and improving the quality of fruit juices rich in tannins. Gallic acid is applied in the drug industry, and production of antioxidants is used in the oil industry. In this study, Tannase was produced by locally isolated Bacillus licheniformis using spent tea as substrate ...

Who Plays the Role? Is it Millennial Farmers? A Case Study in Pagelaran District, Malang Regency, Indonesia
(2023-12-28)
The Ministry of Agriculture is initiating the birth of millennial farmers as an alternative to accelerate farmer regeneration, including through the Youth Entrepreneurship and Employment Support Services Programme (YESS Programme). After seeing the background of youth unemployment, one of the issues that can be identified in the stakeholder analysis of the YESS program is the effectiveness of the program in addressing youth unemployment. Research related to stakeholder role analysis has been widely used for various ...

Association between metabolic and immunological changes during the transition period of dual-purpose cows in the Veracruz tropic, Mexico
(2023-12-30)
The objective of this study was to identify changes and associations in body condition score (BCS), serum glucose and β-hydroxybutyrate (BHB) concentrations, and white blood cell populations in dual-purpose cows during the transition period in the Veracruz tropic. BCS was evaluated and blood samples were taken weekly to determine white blood cell populations, serum glucose and BHB concentrations of 30 multiparous dual-cows (Bos taurus × Bos indicus) from 3 weeks before the expected date of calving to 3 weeks postpartum. ...

Determination of consumer milk price in the informal dairy market in Bangladesh: A district level analysis of vertical system linkage
(2023-12-30)
The objective of this study was to identify the determinants of consumer milk prices and test the hypothesis that input prices, e.g., rice straw and wheat bran, as well as the farmgate milk price exert an influence on the consumer milk price. A unique panel dataset from July 2018 to June 2021 was obtained from the Integrated Dairy Research Network (IDRN) Bangladesh Monthly Dairy Sector database and was analysed using the Generalized Methods of Moments (GMM) methodology. The data collection and validation were done ...

Effect of different levels of fluted pumpkin leaf (Telfairia occidentalis) in grower rabbit diets: Assessing growth parameters, haematological profiles, and serological responses
(2023-12-31)
The effect of fluted pumpkin leaf (FPL) on the growth performance, haematology, and serology of growing rabbits were examined. Seventy-five weaned rabbits of Dutch breed, with a mean weight of 513 g, and different sexes were allotted into 5 treatments with 3 replicates and each replicate housing five weaned rabbits. The five treatment diets were formulated to contain FPL at inclusion levels of 0 % (control), 30 %, 50 %, 70 % and 100 % in a completely randomized design. The animals were fed twice daily and given water ...

Delaying Ripening of Cantaloupe fruits by Various Treatments During Storage
(2023-12-28)
This study was conducted for two seasons 2021 and 2022 to investigate the influence of Putrescine (PUT) at 0.1 or 0.2% and Spermine (SPM) at 0.1 or 0.2% and Chitosan (CS) at 1000 or 2000 ppm and in addition untreated control on quality attributes and delaying ripening of cantaloupe fruits (cv. Primal) during storage at 5º C for 28 days. The results indicated that all treatments were effective in reduced weight loss and color changes and maintained, fruit firmness, TSS, sugar content, total carotenoids and overall ...

Effect of mulberry (Morus alba L.) leaf enrichment on antioxidant, textural, and sensory properties of cassava pasta
(2023-12-28)
Mulberry leaf is usually employed for sericulture in various parts of the world; however, its potential utilization for human consumption is not widely recognized. This study aimed to determine the suitability of using mulberry leaf powder (MLP) as a novel ingredient for the improvement of the nutritional and bioactive profile of cassava pasta while maintaining favorable textural and sensory attributes. Three pasta formulations containing 2, 4, and 6 % MLP were developed. Positive relationships between the level of ...
