Happy Sports is a teaching method that focuses on the future, faces all students, starts from students' interests and sports needs, and gradually cultivates students' ability to carry out physical exercise spontaneously through curriculum design. This paper discusses the definition, connotation, characteristics and implementation principles of happy physical education teaching method through the methods of literature, expert interview and logical analysis, and analyzes the application of happy physical education teaching method in college physical education.

In this study, the producing of conical parts through backward extrusion has been numerically investigated. The finite element method has been used in order to extract the deformation behavior of 7075 aluminum alloy under this process for manufacturing of conical parts. The effect of friction on the process load has been investigated. The strain distribution has been studied and it was observed that in this process, the amount of plastic strain applied to the deforming part has reached above 2, which indicates that in this process, suitable mechanical properties can be expected from the manufactured part.

Social media is recognized by the innovatively minded, as an excellent means to increase business, as the ever-increasing use of social media by populations around the world presents many points of engagement with existing and new customers. The outreach may an imperative for businesses to increase consumer engagement as an additional communication channel to market products and services, as the disruptions with inflation, decreased consumer confidence, and the ravages of the pandemic have wreaked significant losses to businesses worldwide. The barrier to consumer engagement however may be sub-optimal, when social media marketing (SMM) strategies fail to innovatively and unreservedly lag in the adeptness to engage consumers, which may present missed opportunities for small business managers (SBMs) to generate sales. Keeping pace with technological and consumer trends is vital to increase business success and lower risks in sustainability, reinforced by the theoretical lens that the theory of diffusion of innovation (DOI), provided, the purpose of this qualitative exploratory multiple case study was to study the strategies that SBMs use to develop and effectively implement SMM strategies, in increasing existing and prospective customer engagement. The sample purposively drawn from the study population, was six business managers and owners from six different successful small businesses in Maryland. The participation criteria of study participants were demonstrable and verifiable success in using social media marketing strategies successfully for five years, in marketing to existing and new customers. Semi-structured interviews were used in data collection, and with the invocation of a multiple case study design, the analysis also involved the examination of financial and other documents of industry and company respectively. The findings of this study may be of value to SBMs as the knowledge of the SMM strategies discerned from the study may provide insights into formulating and executing social media business and marketing strategies, which advance customer engagement. Business knowledge and the judicious implementation of it can contribute to economic success, which usually translates into positive benefits for society

The originality of a design is directly proportional to the time taken to make it, but from the financial perspective this can cost the organisation a fortune, owing to the competition that it has to face in the live market. It is for this reason that many organisations tend to look for designs that are already available to be used as a reference so that they can build their design on those lines. What matters is the originality of the reverse-engineered design. It is indeed a challenge that shall be attempted to be presented through this paper. The paper shall introduce certain basic concepts like reverse engineering, originality of designs, customer specific mindset and shall thereafter elaborate certain factors that greatly affect reverse engineering, which include technical, commercial and practical aspects. The output of reverse engineering thus done maintaining originality shall be understood from the viewpoints of technical feasibility, commercial viability and manufacturability from the practical perspective. This paper shall stress upon the challenges that a designer needs to face while carrying out reverse engineering and the balance that needs to be maintained between cost, originality and optimum parameters. In addition to these topics, this paper shall also try to present certain risk and opportunity analyses so that a complete picture of the concept can be drawn. The paper shall conclude with the summary of challenges and the means to mitigate the same so as to ensure that a reverse-engineered product does not happen to be a replica of another design but becomes an optimised design by itself.

The goal objective of this study is to propose a new double ARA transform (DARAT). We employ this transform to prove the convolution, existence and other relevant theorems as well as derivatives properties. Subsequently, this transform is applied to solve some illustrative integral- differential equations. This approach was shown to be a powerful and efficient means to tack integral- differential equations.

Crohn's disease is a chronic disabling inflammatory disease affecting the entire digestive tract. The development of biotherapy, in the forefront of which are the anti-TNF alpha drugs, has led to changes in the management of this disease, particularly in terms of improving fistulising forms of the disease outside the anoperineal lesions. We report on the evolution of fistulising Crohn's disease excluding APL under biotherapy.

Soft cheese, often referred to as “Wagashi” in Ghana and parts of West Africa, was produced from cow milk using sodom apple, lime juice and rennet as coagulants. The effects of these coagulants on the yield, physicochemical properties and sensory properties were evaluated. With 3000 ml of milk, the percentage of cheese yield was 23.58%, 21.8% and 19.8% for sodom apple, lime and rennet, respectively. The volume of whey obtained using sodom apple extract was 2100 millilitres, while lime juice and rennet produced 2000 ml and 2200 ml of whey, respectively. The average pH of sodom apple cheese was 5.02, while that of lime juice and rennet was 5.10 and 5.35, respectively. Total titratable acidity values recorded were low, ranging from 0.0072% to 0.00965%, with no significant difference between all the treatments. The moisture content was high in rennet cheese (62.18%), while that of lime and sodom apple were 59.45% and 52.33%, respectively. For free fatty acids, rennet cheese was highest at 12.95%, and lime samples recorded the lowest at 4.65%. Sensory acceptance of samples revealed an acceptance for lime as a coagulant, with the least mean rank of 43.9 over rennet (63.3). The implication of lime acceptance is the readily commercial use and production of soft cheese.
