L’objectif de notre étude a été de mettre en relief l’efficacité du phénomène d’adsorption en utilisant comme matériau adsorbant l’argile pour éliminer les eaux contaminées par la Lévofloxacine. Des billes d’argile environ 0,3 cm de diamètres ont été fabriquées et activées thermiquement. Diverses matrices telles que l'eau ultra pure et l'eau de rivière contaminée par la Lévofloxacine à des concentrations différentes ont été prises en compte. Deux expériences ont été réalisées à savoir, l’adsorption par hydrolyse et l’adsorption par l’argile.

It Synthesis of 2-phenyl benzimidazole derivatives by oxidative condensation reaction with o-phenylenediamine (1.05 mmol), substituted benzaldehyde (1 mmol), catalyst cobalt (II) acetylacetoneand solvent CH3OH stirring at room temperature for 4 hours. Solubility experiments showed that the cobalt (II) acetylacetone is miscible with methanol and relatively readily soluble in polar solvents such as ethanol, and they are partially immiscible with no-polar solvents such as ethyl acetate, and tetrahydrofuran. The efficiency of the reaction was mainly affected by the amount of the catalyst.

Indian Knowledge System (IKS) is a vast body of knowledge deeply rooted in Indian culture, encompassing disciplines such as philosophy, spirituality, science and medicine. It is evidenced by its massive collection of intellectual texts, manuscripts and its well-documented heritage of texts, thinkers and philosophical schools in a wide range of subject areas. The IKS emphasize holistic well-being by using knowledge for self-purification, liberation and addressing contemporary challenges through ancient wisdom.

Higher education institutions continuously seek innovative approaches to track and assess alumni employability to improve academic programs and career support services. This study explores the use of predictive analytics in higher education, specifically employing the Autoregressive Integrated Moving Average (ARIMA) model to forecast alumni employability trends at Pamantasan ng Lungsod ng Pasig (PLP).

In [22], Kumar introduced the notion of b2-multiplicative metric space. Czerwik [2] generalized the concept of metric space and put the idea and terminology of b-metric space. In [15] B. Surender Reddy et al presented the concept of 2-multiplicative metric space. In this paper we introduce the concept of R-weakly commutative mappings on b2-multiplicative metric space. Also we prove a common coincidence point theorem for two pairs of R-weakly commutative mappings on b2-multiplicative metric space.

Cooking is a transformation technique (preparation) by exposure to heat. This heat generally comes (in our regions) from wood, thus causing deforestation. To this can be added diseases due to the soot produced during the combustion of wood. The sun, this source of available and free energy can be used to replace wood for cooking. The development of solar cookers is proving to be a necessity for countries with strong sunshine. This work consists of setting up a solar cooker type reflector box and determining its performance in the city of Ouagadougou.

It is well-known that entangled particles have stronger correlations than what is permissible in classical scenario. Entanglement is exploited in the field of quantum computation and quantum technologies. In this era of Noisy Intermediate-Scale Quantum (NISQ) machines one is concerned with tackling quantum noise in order to establish their advantage overclassical digital computers. Here we study the performance of IBM open access 7-qubit quantum processor ibmq_nairobifor Bell state tomography.

HID attacks have gradually made up as one of the major cyberspace threats that currently exist as far as current exploitations by decent operating systems are concerned, intended only for trusting USB devices. The attacks included the use of compromised USB devices for payload delivery using applications such as BadUSB and Rubber Ducky in commands to avoid security mechanisms and gain unauthorized access to the system's mechanisms.

In this work, thanks to 3D modelling, we were able to express the effective broadcast length as a function of dimensions (x, y) of crystal, loss rate at the limits of x and y, temperature and magnetic field, based on the distribution of carriers in the base volume, obtained from the minority carrier continuity equation. The effective broadcast length and short circuit current were calculated as a function of grain size, magnetic field and temperature.

This Naturopathy is a form of healthcare that combines modern treatment with traditional methods. It includes alternative, natural therapies to modern medicine. Naturopathy, is a system that uses natural substances to treat the patient. It also considers the environmental factors involved which on the whole disturbs the normal functioning of the body. The techniques of naturopathy are a blend of modern and traditional methods. Naturopathic treatment includes diet and clinical nutrition, homeopathy, physical medicine, pharmaceuticals and minor surgery.
