“…The results were strongly agreement with the findings of Abo-Elkasem et al, 1 Farahbod et al, 16 and Mousazadeh et al 22 as they reported that the distilled water prepared through collector was free from the impurities and the results were similar with the present study results. The results were in agreement with the findings of Soteris 50 and Vivar et al 51…”

The distilled water production by the application of the parabolic trough solar collector technology has its significant importance that still needs further exploration. The current study represents the modification of parabolic trough solar collector, with the using of solar tracking tilt sensor with the continuous water circulation rate of 0.22 kg/s to enhance the productivity of the parabolic trough solar collector, and the tracking system consisting of low-speed 12 V motor units of 0.75 r/min and torque of 50 N m was found suitable for the tracking mechanism. The collector received 476 W/m2 with the highest amount of distilled water up to 6675 ml/h m2 during the months of August and the 121°C temperature was recorded during the experiment. The efficiency was noted 31% for the month of August due to the highest absorbing solar irradiance. It was concluded from the results that the tested values of pH and EC in distilled water were decreased from the initial values with the process of distillation through parabolic trough solar collector. Further, from the results, it was concluded that the PTSC was working efficiently with the highest amount of distilled water with the solar tracking tilt sensor and higher efficiency from 08:00 AM to 16:00 PM during the daytime. Furthermore, recommended by the results of the experiment that the amount of distilled water produced significantly depends on the amount of energy input on the concentrator. At last, the distilled water quality was measured and the results were found acceptable for the standard of the Environmental Protection Agency.

“…In our web service, there are six indices; the Accumulated Growing Degree Days (AGDD) is the index for predicting the growing stage of fruit; the Growing Season Temperature (GST) is the index for deciding the species suitable in the temperature of the place; the Coolnight Index (CI) is the index that indicates how much secondary metabolite is contained in the wine grape; the Heliothermal Index (HI) is the index which uses the daily temperature and solar irradiance to evaluate the mass of photosynthetic products; the Biologically Effective Degree Days (BEDD) is the index which uses the daily temperature difference between highest and lowest in addition to the daily temperature as parameter to predict maturity of the wine grape; and the Dryness Index (DI) is the index which uses the temperature, relative humidity, precipitation, wind speed and solar duration as parameters to recognize the soil dryness state [11]. In addition to these indices, our service provides the solar duration data using the algorithmic program invented by Slob and Monna [12]. …”

We have tried to develop the guidance system for farmers to cultivate using various phenological indices. As the sensing part of this system, we deployed a new Wireless Sensor Network (WSN). This system uses the 920 MHz radio wave based on the Wireless Smart Utility Network that enables long-range wireless communication. In addition, the data acquired by the WSN were standardized for the advanced web service interoperability. By using these standardized data, we can create a web service that offers various kinds of phenological indices as secondary information to the farmers in the field. We have also established the field management system using thermal image, fluorescent and X-ray fluorescent methods, which enable the nondestructive, chemical-free, simple, and rapid measurement of fruits or trees. We can get the information about the transpiration of plants through a thermal image. The fluorescence sensor gives us information, such as nitrate balance index (NBI), that shows the nitrate balance inside the leaf, chlorophyll content, flavonol content and anthocyanin content. These methods allow one to quickly check the health of trees and find ways to improve the tree vigor of weak ones. Furthermore, the fluorescent x-ray sensor has the possibility to quantify the loss of minerals necessary for fruit growth.

“…Fossil fuels detrimentally affect the natural environment and introduce about 20 9 10 12 kg of carbon dioxide into the atmosphere [1,2]. The world is increasing, often turning, towards renewable energy [3][4][5], and more specifically towards solar radiation [6][7][8][9][10]. At present, silicon-based photovoltaic panels are the most commonly used [11][12][13].…”

Among many chemical compounds synthesized for third-generation photovoltaic applications, quinoline derivatives have recently gained popularity. This work reviews the latest developments in the quinoline derivatives (metal complexes) for applications in the photovoltaic cells. Their properties for photovoltaic applications are detailed: absorption spectra, energy levels, and other achievements presented by the authors. We have also outlined various methods for testing the compounds for application. Finally, we present the implementation of quinoline derivatives in photovoltaic cells. Their architecture and design are described, and also, the performance for polymer solar cells and dye-synthesized solar cells was highlighted. We have described their performance and characteristics. We have also pointed out other, non-photovoltaic applications for quinoline derivatives. It has been demonstrated and described that quinoline derivatives are good materials for the emission layer of organic light-emitting diodes (OLEDs) and are also used in transistors. The compounds are also being considered as materials for biomedical applications.
