This control is always needed before the service of machines and equipment. For 0.5 hours evaluate the work of oils, prevent their late change and accident.
Means of verification

The crucible 75.100 ml, thermometer 250 °С, device for the slow controlled heating of the oil to 220 – 235 °С, filter paper.Determine the temperature of the beginning and end of crackling/foaming/boiling oil when it is watered, flash point, decreasing due to loss of viscosity. An oil stains (“drip sample”, Figures 1&2) on filter paper after 15 - 20 minutes characterizes the contamination, washing, dispersing properties, water cut and overheating of the oil.

Gully Erosion and Landslides in Southeastern Nigeria: Causes, Consequences and Control Measures

Image
  Abstract In southeastern Nigeria, soil and gully erosion and landslides are responsible for the widespread destructions of human, animal and plant lives, domestic, industrial and commercial property, transportation and communication systems, degradation of arable lands, contamination of surface and groundwater supplies, isolation of settlements and migration of communities. This account presents some of the results of research and studies of gully erosion and landslides carried out over the years in parts of southeastern States of Abia, Anambra, Enugu, Ebonyi and Imo States. Gully erosion is attributed to natural and anthropogenic causes, with the latter being most prevalent. Gully initiation is the result of localized erosion by surface runoff and soil eluviation associated with rainfall events of high intensity. Erosion is frequently concentrated where the forest cover has been removed for agricultural, urbanization and construction purposes and also at sites of u...

  Biological Processes In Urban Mines Authored by Navarro Hidalgo Keywords: Critical elements; Microorganisms; Urban mines; Biological processes; Recycling Introduction The innovation and development of high technology have demanded the exploration of some chemical elements in greater quantity. These elements have physicochemical properties of high economic interest. Some countries have larger amounts of the reserves of these elements, creating an imbalance in world supply. An example of the use of these materials are rare earth elements widely used in equipment with greater energy efficiency and magnets in wind generators. They are also present in increasingly modern computers, cell phones and televisions. Given this reality, thiswork proposes to recover critical elements from alternative sources (electronic waste - REE) using a biological process as a tool for  solubilization of waste elements with subsequent recovery. The proposed technique is bio-hydrometallurgy, already...

Importance of technology acceptance assessment for successful implementation and development of new technologies

Introduction It is significant to note that user acceptance and confidence are crucial for further development of any new technology [1,2]. Businesses have facilitated or planning to facilitate their business platform to increase personnel efficiency, marketing improvement, cost reduction and increase profitability. Therefore, recognition the needs and acceptance of individuals is the beginning stage of any businesses and this understanding would be helpful to find the way of future development [3-5]. In general, acceptance is defined as “an antagonism to the term refusal and means the positive decision to use an innovation” [6-8]. Decision makers need to know the issues that influence on users’ decision to use a particular system, so they would be able to take them into account during the development phase [7,8]. Several researches developed theories and models to describe and analyze user acceptance and each of these models determines different factors to explain user acceptance ...
