Title : Inhibition of the growth of Pseudomonas aeruginosa bacteria by extract of Bassia muricata L.

In the present study, the test of the susceptibility of the plant Bassia muricata L., through the effect of the extract of hot water on the bacteria (Pseudomonas aeruginosa). Where the plant was collected from Baghdad and different areas along the banks of the Tigris River. The histological sections of the stem were examined and studied. The stems of the young plant were characterized by thick Sclerenchyma. Soil samples were collected from different areas on the banks of the Tigris River after soil examination was isolated and diagnosed with Pseudomonas aeruginosa.

Results showed laboratory study, the hot water extract of Bassia muricata L. was highly effective in inhibiting the growth of Pseudomonas aeruginosa. The objectives of the study are the need to look for alternatives to antibiotics for diseases; given the risks posed by the use of antibiotics; the development of microbial resistance; and the inefficiency of traditional methods to control disease elimination. There is a need to encourage researchers to find plant alternatives and less toxicity, less toxic, less dangerous, and cheap and effective, not as polluting to the environment as possible, for this reason, this study of the effect of hot water for Bassia muricata L. extract on the growth of bacteria in the laboratory. This plant has been selected for its abundance as a wild plant prevalent in Baghdad. The main objective of this study is to use alternative medicines, which will be available, safe, and cheap instead of the high costs and somewhat harmful drugs.

Title : Tidal Head Early Warning System Using LoRa

The surge of water flow (SWF) in a river is a dangerous phenomenon that occurs along the water stream. SWF can create an even more dangerous situation called tidal head (TH). High rainfall rates cause river water levels to rise, with high currents leading to TH. Heavy downpour at the upstream creates sudden increase in river water and brings along silts, rocks, branches, and logs, where it rams everything in its path as water travels downstream. In tropical countries, rivers are one of the most popular recreational spots. Tourists engaged in activities such as swimming are unaware of the presence of TH, and they have no time to evacuate. This situation can cause injuries and even fatality. One of the ways to prevent the catastrophic effects of TH is to detect it early. Hence, a TH warning system based on LoRa network technology is developed to prevent accidents or death risks. The system is designed to provide early warning to tourists and the safety personnel monitoring the river and the waterfall. The warning comes in the form of a physical siren and an alert notification via a website accessible through a computer or smartphone. The system prototype consists of LoRa module that remotely transmits warning data with the help of Arduino and water sensors. The prototype is designed to monitor part of the river where the sensors are mounted to the distance where the siren can be heard, and a web application is monitored by the safety personnel or forest wardens to alert the tourists about the occurrence of a TH.
