Chicken feather particles reinforced rubber seed oil based polyurethane composites were produced and the physico-mechanical and microstructural analyses were studied. Casting method was used to produce the composites with varied weights of Chicken feather particles from 5 to 25wt% in steps of 5 wt%. The composites produced were analyzed for hardness, impact strength, tensile strength, density and water absorption properties according to ASTM standards. The density and impact strength were observed to decrease with increase in percentage weight of the chicken feather particles and this was attributed to the fact that the feathers have lower density than RSO-Polyurethane. Tensile strength and hardness of the composites were found to decrease at the intial stage (0 to 10 wt%) and later started to increase with percentage increase(15 to 25 wt%) of reinforment added. The microstructure reveals that there was a reasonable uniform distribution and bonding of chicken feather particles in the RSO-Polyurethane matrix.

This paper aims to prepare new modified alkyd resins and use it as an antimicrobial binder for surface coating applications.

Various modified alkyd resins were prepared by partial replacement of 3,6-dichloro benzo[b]thiophene-2-carbonyl bis-(2-hydroxy ethyl)-amide as a source of polyol with glycerol and confirmed by acid value, FT-IR, 1H-NMR. The modified alkyd resins were covering a wide range of oil lengths and hydroxyl content (0%, 10%, 20% and 30% excess-OH). The antimicrobial activity of the prepared alkyds was also investigated. The coatings of 60 ± 5 µm thickness were applied to the surface of glass panels and mild steel strips by means of a brush. Physico-mechanical tests, chemical resistance and antimicrobial activities were investigated.

The obtained results illustrate that the introduction of benzo[b]thiophene derivative as a modifier polyol within the resin structure improved the film performance and enhanced the physico-mechanical characteristics, chemical resistance and the antimicrobial activities.

The modified alkyd resins can be employed as antimicrobial binders in paint compositions for a variety of surfaces, particularly those that are susceptible to a high number of bacteria.

Modified alkyd resins based on antimicrobial heterocyclic compounds have the potential to be promising in the manufacturing of antimicrobial coatings and development of paints, allowing them to function to prevent the spread of microbial infection, which is exactly what the world requires at this time. Also, they can be applied in different substrates for industrial applications.

This chapter explores geopolitics, garbage cans, the need for interdisciplinary insight, and the lures and limitations of one-sided mono-disciplinary conceptual models in understanding strategic decision making. We argue that a combination of the garbage can model and Nathan Leites’ psycho-cultural approach to decision making might be useful in giving insights for events and for organizational behavior. As a decision making case, we consider the 1941 decision of the Empire of Japan to declare war on the Allied Powers. We find that there could be useful lines of integration between the garbage can framework and other perspectives in geopolitical decision making. In using a historical example to illustrate the possible integration, we argue that there are inherent limits to single-model decision making approaches. Developing interdisciplinary frameworks for understanding foreign policy decision making may lead to better insights in real-world processes and seems like a step in a fruitful direction.

Sociological studies of entrepreneurship focus on social and technical innovations in business. Using an illustration from molecular plant biology and the historical evolution of the term “entrepreneur,” I make a case for the theoretical and methodological importance of studying entrepreneurs and their ventures outside the scope of traditional business. Then, considering the scientific lab as a self-consciously entrepreneurial venture, I use the population of molecular biology labs studying the plant Arabidopsis thaliana to demonstrate a relationship less directly measurable among start-ups in business: diverse sources of funding accompany original activities and ideas within a venture. This is not, however, what predicts lab success. Lab size drives success, but hinders originality. Moreover, I show that established institutions in science are usually the ones that become innovations in business.
