IoT deals with interconnection of devices and LiFi is a medium to achieve networking. Hence Light Fidelity (Li-Fi) is the biggest facilitator of IoT and Big Data. Li-Fi is a wireless technology which enables bi-directional and high speed data transfer. LiFi could be installed anywhere users might like light and data services: bus shelters, train stations, street lights, tourist information kiosks could all provide data transmission as well as light. As the market for IoT devices grows and sensors are added to more and more things and places, faster and heavier data transmission will be required. Our current infrastructure simply cannot handle the quantity of data that will need to be transmitted if the IoT continues to grow at predicted rates. LiFi may be the only viable solution if we want Big Data and the IoT to continue to grow

with the advent of the information communication technology , world have become a town , the demand of the technology is uprising vertically and horizontally in terms of development of the nation and its economy. Today if we look on the retails market or any other traditional and professional business or service, we find the integrated role of the communication technology, and its proportionate relationship with the business development.Service sector with the use of ICT are more profitable and tangible benefits in terms of the returns and the sustainability. To prototype the frame work of national communication channel to meet the demand of the service of ICT by the society and the requirement of Energy to meet and sustain the frame work of communication Technology , LI-Fi may play an important and vital role. The national mission of digital India may bring the fruits with the development of the LI-Fi Communication Technology.Present paper enlight the issues and solution to prove the LI-Fi as one of the pioneer technology which is clean and green.

The aims of this study to estimate the concentration of nitrates in different types of fresh leafy vegetables in Tripoli (Janzour). The study included several samples (cabbage, spinach, watercress, paper lettuce, romaine lettuce, dill, coriander, parsley, celery and celery). Nitrate was determined in the samples using a NitraVer 5 high range test, where nitrate ion (NO3 -) is reduced to nitrite ion (NO2 -) by cadmium, and nitrite ions reacts with Sulfanilic acid to be the diazione salt. Diaconium salt, which combines with gentisic acid Hermany, and the intensity of the color depends on the concentration of nitrate solution in the sample. Samples were measured using a device (Spectrophotometer DR1900), The analysis results were compared to each other, as well as the results obtained of previous studies of other countries.

Author Keywords:- Nitrates, Spectrophotometer, Vegetables, Diaconium salt, Sulfanilic acid.

This study has two methods, which are applied to the PV system to protect it and cool it from overheat. PV system in Saudi Arabia faces high temperatures and dust which is available at the most days of the year. In addition, a high weather temperature affects the efficiency of the PV system; the method of cooling PV panels will improve and increase the efficiency of the PV system. Two methods were used to PV system, the first method, is hydro-cooling by using water to cool PV panels and the second method, is the Nano Ceramic isolation. The results show that hydro-cooling module is suitable for PV systems in KSA, and it can increase the efficiency of the PV systems on one side, and decrease the temperature of the system on the other side. Nano isolation is protecting the PV systems and would be suitable for weather condition in KSA but would reduce the efficiency of the PV system as a side effect, which is not suitable for mass production or industrial production.

Author Keywords:- PV system, Water cooling-cleaning, Nano ceramic isolation, Digital Multi Meter (DMM), Vision 2030.

Directional microphones are used in popular car multimedia systems, such as CAR PLAY and ANDROID AUTO. The driver can command the microphone to control the car multimedia system. The directional microphone can also improve speech recognition accuracy and prevent the microphone from receiving noise from outside the car. This research improves array microphone directivity. Delay-and-sum beamforming method is used in most systems to achieve the desired directional microphone array effect. However this study used 57 circular array microphones with delay-and-sum beamforming combined with the
optimization method to control the directivity of the microphone array. The results show that the proposed method significantly improves microphone array directivity.

Author Keywords:- Directional microphone; microphone directivity; delay-and-sum beamforming; optimization method.
