A new type of waterproofing composite emulsion with high silane content and good economic efficiency was synthesized by sol synthesis. The effects the amount proportion compound emulsifier, tetraethyl orthosilicate, mixing time on properties emulsifier were investigated. optimum conditions for synthesis a orthosilicate/isobutyl triethoxysilane determined. characterized infrared spectroscopy, th...

The article considers using a single-layer reinforced ten-centimeter layer of concrete on stress cement instead the traditional multilayer construction waterproofing bridges. proposed design will ensure water tightness bridge deck due to self-stress in stressing cement, value which is proportional deformations and reinforcement. Concrete are uneven over height, resulting depends reinforcement c...

Oenocytes are large secretory cells present in the abdomen of insects known to synthesize very-long-chain fatty acids produce hydrocarbons and pheromones that mediate courtship behavior adult flies. In recent years, oenocytes have been implicated regulation energy metabolism. These hepatocyte-like accumulate lipid droplets under starvation can non-autonomously regulate tracheal waterproofing ad...

Background: The security of the state is a priority task in science modern conditions. Transportation area as one most important areas for sustainable functioning, requires special attention. It very to research scientific approaches and their implementation providing at transport. Due large concentration passengers station complexes, attention should be paid keeping them working condition.&#x0...

Ground water tank atau dalam bahasa Indonesia yang sering disebut dengan tangki air bawah tanah, merupakan salah satu bentuk bak penampungan dirancang berada di permukaan tanah. biasanya menggunakan material pelat beton bertulang dilapisi waterproofing non-toxic (tidak beracun). Sulitnya memonitoring sebuah pada ground karena letaknya maka dari itu muncul inovasi sistem monitoring ketinggian be...
