Saving Global Fisheries: Reducing Fishing Capacity to Promote Sustainability
The Earth’s oceans are overfished, regardless of greater than fifty years of cooperation one of the world’s fishing international locations. There are too many boats chasing too few fish. In Saving worldwide Fisheries, J. Samuel Barkin and Elizabeth DeSombre examine the matter of overfishing and provide a provocative thought for a world regulatory and coverage strategy.

Polyurethane is generally synthesized from the isocyanate reaction with polyol. Polypropylene glycol (PPG) is a polyol, is basically derived from the petrochemical industry [3]. High rising costs of petrochemical feedstock’s and enhanced public desire for environmentally friendly green products, utilization of renewable resources to manufacture the rigid polyurethane is a work necessary at the present time [4-6]. Castor oil is one of the major natural vegetable oil that contains a hydroxyl group and so it is widely used in many chemical industries, especially in the production of polyurethanes [10].
The presence of larger organic chains in castor oil mixed polyurethanes resulted in a larger oxidative thermal stability, over pure PPG polyurethanes. A slower cell formation was also observed in mixed polyurethanes, exhibiting a controlled synthesis. Further studies will be done to enhance the mechanical properties by applying nanofillers.

Introduction Pearlescent pigment is one of the color effect materials which composed of a highly reflective platelet-shaped substrate encapsulated with a low index of refraction material [1]. It is widely applied in plastics, printing ink, cosmetic and ceramic materials due to its unique decorative optical color effects and weather-resistance effects [2]. The common substrates of traditional pearlescent pigment were mica or synthetic mica [3]. The defect of the mica or synthetic mica based pearlescent pigment are these: 1.
