Selected papers on Hands-on Science II

This second volume of the "Selected Papers on Hands-on Science" the Hands-on Science Network is publishing, reunites some of the most relevant works presented at the 2008, 2009, 2010 and 2011 editions of the annual International Conference on Hands-on Science. From pre-school science education to lifelong science learning and teacher training, in formal non-formal and informal contexts, the large diversified range of works that conforms this book surely renders it an important tool to schools and educators and all involved in science education and on the promotion of scientific literacy.info:eu-repo/semantics/publishedVersio

2021 Student Symposium Research and Creative Activity Book of Abstracts

The UMaine Student Symposium (UMSS) is an annual event that celebrates undergraduate and graduate student research and creative work. Students from a variety of disciplines present their achievements with video presentations. It’s the ideal occasion for the community to see how UMaine students’ work impacts locally – and beyond. The 2021 Student Symposium Research and Creative Activity Book of Abstracts includes a complete list of student presenters as well as abstracts related to their works

Special oils for halal and safe cosmetics

Three types of non conventional oils were extracted, analyzed and tested for toxicity. Date palm kernel oil (DPKO), mango kernel oil (MKO) and Ramputan seed oil (RSO). Oil content for tow cultivars of dates Deglect Noor and Moshkan was 9.67% and 7.30%, respectively. The three varieties of mango were found to contain about 10% oil in average. The red yellow types of Ramputan were found to have 11 and 14% oil, respectively. The phenolic compounds in DPKO, MKO and RSO were 0.98, 0.88 and 0.78 mg/ml Gallic acid equivalent, respectively. Oils were analyzed for their fatty acid composition and they are rich in oleic acid C18:1 and showed the presence of (dodecanoic acid) lauric acid C12:0, which reported to appear some antimicrobial activities. All extracted oils, DPKO, MKO and RSO showed no toxic effect using prime shrimp bioassay. Since these oils are stable, melt at skin temperature, have good lubricity and are great source of essential fatty acids; they could be used as highly moisturizing, cleansing and nourishing oils because of high oleic acid content. They are ideal for use in such halal cosmetics such as Science, Engineering and Technology 75 skin care and massage, hair-care, soap and shampoo products

Australian agricultural restructuring and farmers’ responses: a case study of the Illawarra region, New South Wales

Rural geography has become an increasingly important subdiscipline of human geography since the 1980s. Over the past decades, farming in most developed countries has been transformed at a speed and to an extent that is unprecedented. Much of rural Australia has been experiencing constant financial difficulties which drove the restructuring of agricultural industries. Despite the importance of supporting family farmers and rural communities in terms of food security and sovereignty, there is still very limited theoretical and empirical knowledge regarding how the multiple forces over the past decades have intertwined and impacted farm development pathways. By focusing on dairy farmers‘ (in the Illawarra region, New South Wales) experiences of and responses to agricultural restructuring, this thesis aims to characterise and interpret change in contemporary agriculture. Conceptually, agricultural restructuring has been researched from political economy and socio-cultural perspectives, which have alternately dominated the research agenda of human geography, and are both deployed in this study. Dairy farming dominates Illawarra agriculture, and has been constantly pressured by neoliberal policy reform (especially nationwide deregulation of the dairy industry in 2000), industry restructuring and the inflow of urban middle-class groups into rural areas. To maintain the century-long tradition of family farming, Illawarra dairy farmers do not just work hard but seek to improve their business from various angles. This process drives continued productivism, the rise of alternative agri-food networks, and the multifunctional transition of local agriculture. The thesis brings together scholarship examinng the pathways of agricultural transformation, changing perspectives of farming businesses, and on-farm development

Challenges for engineering students working with authentic complex problems

Engineers are important participants in solving societal, environmental and technical problems. However, due to an increasing complexity in relation to these problems new interdisciplinary competences are needed in engineering. Instead of students working with monodisciplinary problems, a situation where students work with authentic complex problems in interdisciplinary teams together with a company may scaffold development of new competences. The question is: What are the challenges for students structuring the work on authentic interdisciplinary problems? This study explores a three-day event where 7 students from Aalborg University (AAU) from four different faculties and one student from University College North Denmark (UCN), (6th-10th semester), worked in two groups at a large Danish company, solving authentic complex problems. The event was structured as a Hackathon where the students for three days worked with problem identification, problem analysis and finalizing with a pitch competition presenting their findings. During the event the students had workshops to support the work and they had the opportunity to use employees from the company as facilitators. It was an extracurricular activity during the summer holiday season. The methodology used for data collection was qualitative both in terms of observations and participants’ reflection reports. The students were observed during the whole event. Findings from this part of a larger study indicated, that students experience inability to transfer and transform project competences from their previous disciplinary experiences to an interdisciplinary setting
