The efficiency of the anti - erosion agricultural operations is one of the main objectives of the designers for machinery and soil working tools on slopes. Mathematical modelling that using a systemic approach of the phenomena and processes and realistic assumptions, allows the optimum constructive-functional parameters for soil working tools, in order to achieve a properly working with low energy consumption. Storage capacity of the sediment profiles achieved by ground shaping is properly estimated according to the geo - climatic conditions of the area. Previous researches (Cardei, Cota, 2008) led to the establishment of a calculation model in this respect. The method of calculation for choosing the geometry of profiles is the application of the final investigations, in conditions to assure a satisfactory storage capacity of sediments and a minimum energy consumption for the soil working processes.

High comfort and low energy consumption communities have become an important topic for community planning & design in China. Considering the special situation in China, the meaning of high comfort and low energy consumption communities lies in three aspects: making utmost use of natural climatic conditions, providing enjoyable indoor and outdoor living environments in circumstances of high-rise and high-density development, and holistic design of adjacent dwelling units to provide utmost flexibility. This paper uses design proposals for two real projects in two different cities in China - one in Yixing in South China and another one in Harbin in north China - as examples of how to design high comfort and low energy consumption communities by following local climatological factors and by respecting occupants’ needs in the long run. This paper shows that such communities can be planned in two steps, with special attention to the local climate. First, climatically responsive site planning determines building layout, height of each part, and also the design of open spaces. Second, detailed planning & design addresses the disadvantages of the site, improving space quality. Following local climatological conditions is also one of the key issues in housing design for high comfort & low energy consumption communities. In the housing design of the Harbin project, besides consideration to climate, special attention was also given to flexible/variable dwelling unit design according to occupants’ long-term needs. The “1+1 mode” is put forward to provide utmost flexibility for families with 3 generations for their current and future lives.

This paper studies the use of bipolar-particles-electrodes in the decolorization of dyeing effluents. Treatment of highly colored solutions of various soluble dyes (such as direct, reactive, cationic or acid dyes) and also samples of dyeing effluents gave rise to an almost colorless transparent liquid, with removal of CODcr and BOD5 being as high as over 80%. The method is characterized by its high efficiency, low energy consumption and long performance life. A discussion of the underlying principle is given.

Recent market studies show that the market for remote monitoring devices of different medical parameters will grow exponentially. Globally, more than 4 million individuals will be monitored remotely from the perspective of different health parameters by 2023. Of particular importance is the way of remote transmission of the information acquired from the medical sensors. At this time, there are several methods such as Bluetooth, WI-FI, or other wireless communication interfaces. Recently, the communication based on LoRa (Long Range) technology has had an explosive development that allows the transmission of information over long distances with low energy consumption. The implementation of the IoT (Internet of Things) applications using LoRa devices based on open Long Range Wide-Area Network (LoRaWAN) protocol for long distances with low energy consumption can also be used in the medical field. Therefore, in this paper, we proposed and developed a long-distance communication architecture for medical devices based on the LoRaWAN protocol that allows data communications over a distance of more than 10 km.
