Density Functional Theory (DFT) and Time-Dependent Density Functional Theory (TD-DFT) were treated according to Becke’s three Lee–Yang–Parr (B3LYP) correlation potential due to its less error value than other functionals. This molecule has biological studies are useful for fields, due to its thermal stability and less energy bang gap of probe has luminescence applications.

Monitoring technology has advanced dramatically in recent years in various locations, both urban and rural. The Internet of Things (IoT) enables the remote control and collecting of data from sensors for their subsequence analysis. Thus, LiFi was proposed as an enabling technology for IoT in indoor environments. This enables the supermarket automation through the use of IoT topology. However, the absence of mutual trust can create a barrier to implementation. To conduct cryptocurrency transactions, blockchain technology has been widely employed. It has recently shown to be effective in establishing confidence in the Internet of Things (IoT) domain. This paper offered a method for integrating IoT features into supply chains. While strengthening the security of IoT-based supply chain management, our suggested architecture streamlines data sharing and decreases computational, storage, and latency needs.

The objective of this study was to evaluate the agricultural performance in monocropping and in association of tomatoes affected by a few diseases in the city of Kisangani. The study was done following a non-randomized block device comprising two blocks of 6 plots each. Two types of crops were used namely tomato and spinach. The treatments consisted of tomatoes in pure culture and tomatoes in combination with spinach. Observations focused on the evolution of tomato diseases and the number of inflorescences, flowers, fruits, fruit weight, fruiting and yield per plant. The results obtained reveal that the combination of spinach with tomatoes reduces the spread of tomato diseases and increases tomato yield under the conditions of our study. information retrieval systems.

The authors report one case of anorectal malignant melanoma, seen and managed in EFD-HGE Unit, Ibn Sina Hopital . It’s a very uncommun affection of bad pronostic. At the present time, the surgical management is the only therapeutical attitude.

In this research, phytochemical screening and antibacterial properties of Phyllanthus muellerianus were investigated to confirm the potency of the plant on the basis of ethno medicinal significance. The percentage yield of crude methanolic leave extract of Phyllanthus muellerianus was 12.58% while the phytochemical screening of crude methanolic leave extract of Phyllanthus muellerianus revealed the presence of anthraquinone, carbohydrates, tannins, alkaloids, flavonoids, cardiac glycosides, saponin and lipids. The result of the antibacterial activities showed that the crude methanolic leave extract of the plant exhibits high potency against all the tested organisms. These properties above may be the reason Phyllanthus muellerianus plant has been reported to be useful in the treatment of several ailments.

Water is a very essential product in life and has always been the subject of special attention because of its capital importance in the life of man, in terms of its use or consumption. Hence the need for more studies and research in this vital area. Thus, in the context of this study, we also wanted to pay particular attention to the waters of undeveloped wells which proliferate everywhere in the city of Kisangani and which are often used by the population in case of need during rupture. of drinking water supply by Regideso and especially those who do not yet benefit from this water service in their communities.This study concerns the bacteriological and physico-chemical analysis of the water of the wells of the commune of Mangobo and aims to determine the quality of the waters of these wells. The waters from these two wells (1 and 2) were analyzed in the field and in the laboratory. After analysis and processing of the data, the results proved that, compared to the physico-chemical parameters, these waters were out of standard for temperature (?29.1°C), pH (?6.01) and did not contain chlorine (0). These waters therefore do not undergo any treatment and are true culture media in relation to their temperature. From a microbiological point of view, the water from well 1 is of suspect quality (contains an average of 30,000 total germs per 100 ml and 1,300 total coliforms per 100 ml) and is not given for human consumption, while that from well 2 is of fairly good quality. The contamination of these waters is of strictly human origin, therefore coming from its users.This study underlines the importance of carrying out physico-chemical and microbiological analyzes of well water before any consumption by the population of Mangobo because drinking water must not contain pathogenic microorganisms or toxic substances.

Cassia fistula Linn. Belongs to family Leguminosae, Sub – family Caesalpineae, a very common Indian plant is known for its medicinal properties. C. fistula is known to be an important source of secondary metabolites notably phenolic compounds like tannins, flavonoids and glycosides. Pharmacological activities include antibacterial, antidiabetic, antifertility, anti-inflammatory antioxidant, hypatoprotective, antitumor, antifungal activities. This article provides glimpses on morphology, traditional uses and its phytochemical and pharmacological activities.

In this paper we characterized a vertex whose removal increases the perfect domination number of a graph. We also consider the pendent vertices whose removal decreases the perfect domination number.

The field experiment on the influence of three legumes (groundnut, cowpea and soybean) on the agricultural yield and monetary income of an association of six crops (cassava, plantain, sweet potato, maize, rice and/or groundnut, cowpea, soybean), was conducted during two successive cropping seasons in a forest region of the DRC (Bengamisa). The results show that: - The crop association with cowpea numerically improved the agricultural yield of the components, the overall agricultural yield of the association and induced a better overall LER compared to the association with groundnut and soybean. - The crop association with groundnut, on the other hand, yielded a much higher gross margin of $2645.4/Ha, compared to the gross margin achieved by the association with cowpea ($1872.4/Ha) and that with soybean ($1847.6/Ha). - In the crop associations in this environment, cowpea is considered to be a factor in improving crop yields, while groundnuts are considered to be a factor in improving cash income.
