The capital of Guinea, Conakry, faces a notable difficulty due to a water shortage, which is worsened by the rapid increase in population and urban development. The Guinean Water Company (sEG) faces challenges in supplying water to the entire city due to its limited area of approximately 420 kmsup>2sup> and a population of 2 million. Moreover, the population growth rate is anticipated to increase dramatically, exacerbating the difficulty of fulfilling future water requirements. As a result, this study employs data from the Knoema website and the Institute of National statistics of Guinea (INs) to examine the water production and distribution process by the sEG. The study examines the challenges related to water scarcity in Conakry and suggests strategies to assist the city in managing the present circumstances and planning for the future. The primary objective is to get a long-lasting water supply and uphold water quality to advance public health.

This study aims to identify the causes of sensor jams and its impact on the operation of vending machines. The vending machine is a machine that automatically dispenses products such as drinks, tickets, sandwiches and biscuits, by inserting change or credit card into the machine. This technological feat is due to the advent of sensors. A sensor is a part of the measurement chain, it receives the quantity to be measured and provides information directly linked to this quantity. However, these vending robots are faced with malfunctions linked to sensor jams. The identification of the jam phenomenon was possible thanks to the inspection and monitoring of the various sensors installed on the vending robot. And Cadence software was used to model, control and locate the jammed sensor(s). The various tests were carried out by setting the robot in motion to better understand the causes of the phenomenon. The jam is therefore the phenomenon which triggers the sensors permanently, which causes the automatic vending robot to stop functioning. And this jam was due to the presence of water droplets on the sensor or dirt. This presence of water droplets on the sensor is linked to an increase in temperature. Controlling the temperature and locating the jammed sensor has made it possible to considerably reduce jamming and its harmful effects on the vending machine robot.

合成了一种非离子-阴离子Bola型智能表面活性剂,通过pH-响应可以在非离子型CH_(3)O(EO)_(5)-R_(11)-COOH(pHpKa)之间转换。单独使用时,非离子型和Bola型分别表现为不良乳化剂和优良乳化剂。与纳米siO_(2)颗粒复配使用时,非离子型能与siO_(2)颗粒协同稳定O/W(正癸烷)型Pickering乳状液,其中表面活性剂通过氢键作用吸附到颗粒表面产生原位疏水化作用,提高了颗粒的表面活性,并且这种Pickering乳状液具有pH-和温度-双重响应性,能够通过改变pH或者温度使乳状液在稳定和破乳之间实现多次转换。另一方面,Bola型CH_(3)O(EO)5-R_(11)-COONa能够与纳米siO_(2)颗粒协同稳定分散液包油(oil-in-dispersion)乳状液,该乳状液具有良好的耐温性,但对调节pH时产生的盐较为敏感。然而与破乳后能完全返回水相便于回收再利用的同系物CH_(3)O(EO)7-R_(11)-COOH相比,具有较短EO链的CH_(3)O(EO)_(5)-R_(11)-COOH无论处于非离子型还是Bola型状态仍具有相当的油溶性,破乳后不能完全返回水相,表明EO数大小对这类新型智能表面活性剂的性能有显著的影响。

Geotopes or geological sites provide information on the evolution, structure and properties of the Earth's crust and on the geological past. They also represent the great variety of features that characterize a landscape, For this reason, their preservation is of special concern to geosciences. As early as in the 19th century, outstanding rock formations became important tourist sites although the modern terms ""geosites"" and ""geotourism"" were unknown. The paper describes the German initiatives on geotope conservation and the implementation of National GeoParks in Germany and their use for education and tourism.
