Adhesives can be used as sealing agents, to eliminate the effect of self-loosening caused by dynamic loads, areas prevent oxidation and corrosion, waterproofing, so on. The aim present study is prepare an adhesive from fresh cassava roots evaluate its physicochemical properties such density, viscosity, pH. are prepared mixing starch, hydrochloric acid, borax. Three samples adhesives were variou...

Polyurethanes with water expansion properties are manufactured by incorporating polyurethane resins and superabsorbent polymers. This study aimed to present an optimal mixing ratio of a polymer that can express the effective waterproofing performance material properties. The evaluation results confirmed was exerted at more than 10% 150% or more, which were then set as minimum standard value for...

With the expansion of robots, researchers have focused on robot tasks with waterproof functions. Although numerous underwater-robot studies been published recently, there has minimal research waterproofing robotic hands. The aim this study is to develop an underwater gripping control strategy for a hand using glove. By silicone-rubber-based glove, finished task. However, error occurred during t...

Urban heat islands (UHI) represent increase of temperature inside cities in regard to their rural environment. Causes formation are diverse and multiple: reduced amount vegetation waterproofing surfaces, changed radiation thermal characteristics materials, urban geometry. Consequences also significant: increasing consumption energy for cooling, negative impact on human health, deterioration air...
