Using 3d Models And Virtual Reality To Foster Learning Of Carcass Anatomy, Renae Sieck

UCARE: Research Products

In meat science and carcass anatomy, an often-debated topic is the methodology educators should follow for effective and efficient learning of carcass anatomy among students. Many traditional learning environments utilize monolithic methods for teaching anatomy that fail to engage students or pedagogically enhance their cognitive development to the fullest potential. Access is also limited because of the need for specialized facilities’ and equipment. We are interested in understanding and measuring the success of learning tools such as Virtual Reality (VR) and 3D Visualization in student learning. Our study’s results would be useful to indicate if student attitudes and student performance …

Ethically Sourced Vanilla: Certifications In The Production Of Vanilla In The Sava Region Of Madagascar, Maisie Campbell

Independent Study Project (ISP) Collection

Vanilla is an orchid whose beans are harvested after ten months on the vine. About eighty percent of the world’s vanilla is produced in Madagascar and the SAVA region is the capital of vanilla production within the country. The changing demand of vanilla, damage from cyclones, and the three-year development of the vanilla plants before they begin producing beans causes a boom and bust cycle of prices of vanilla. Some organizations have tried to ameliorate the problems these cycles and low prices pose to vanilla farmers by creating certifications for companies that promise that they will not pay less than …

Study Of Rheological, Chemical, And Microbiological Properties Of Chami, A Traditional Emirati Soft Cheese, Aysha Othman Abdullah Al Katheeri

Theses

In this work, ten Emirati Chami cheese samples were collected and analyzed to determine their chemical composition, texture, rheology, and microbiological properties. Chami cheeses showed large variations in moisture (60.9–84.1%), protein (7.5–14.6%), fat (0.5–7.8%), and ash (3.4–8.0%) contents as well as in pH (3.6–4.4), and water activity (0.977–0.999%). The variation in fat content of samples suggested that extra fat was added; this added fat was either butter or vegetable oil as indicated by the fatty acid composition. The different samples showed peaks of variable size for fat melting. The sodium content in the 10 cheese samples varied from 223–2410 mg/kg, …

Food Waste Diversion Programming In Post-Secondary Education, Manar Arica Alattar

Dissertations and Theses

The urgent need for reform of USA and global food systems is evident in the pervasiveness of both food waste and food insecurity. Such an inefficient system strains the environmental, social, and economic systems on which it relies. Although policy and infrastructure changes are essential, consumers can play a significant role by decreasing their food waste, given that consumer waste represents 60% of the waste along the food cycle in developed countries. Incorporation of food literacy and food waste education in school curricula may provide a meaningful entry point for promoting food waste reduction skills.

This dissertation presents context on …

However, due to the perilla oil was …

The Influence Of Online Meal Ordering On Food Safety And Its Legal Regulation, Chen Li

Food and Machinery

Because of the big difference between the network ordering mode of operation and the traditional food and beverage industry, the current “food safety law” has made special provisions on its food safety. However, due to the existing time of network ordering is not long, it still has some hidden trouble on food safety, such as administrative supervision vacancy, the lack of the necessary food safety audit and management mechanism for third party platform, the lack of consumer awareness of food safety. It is necessary to take some legal regulation measures, including establishing a supervision system based on food and Drug …
