Phytochemical Screening and in Vitro Antimicrobial Activities of Euphorbia Lateriflora on Selected Pathogens
...Show More Authors

     Euphorbia lateriflora is a popular traditional medicinal plant whose leaves are used in Africa, especially Nigeria, to treat wounds and many diseases. This study investigated the preliminary phytochemical constituents, secondary metabolites by High-Performance Liquid Chromatography “HPLC” technique, and antimicrobial potentials (Minimum Inhibitory Concentration “MIC”, Minimum Fungicidal Concentration “MFC” and disc diffusion assay) of various concentrations (100 mg/mL, 50 mg/ml, and 25 mg/mL) of the solvents (ethyl acetate and n-hexane) extracts of E. lateriflora against Staphylococcus aureus, Escherichia coli and Candida albicans. The phytochemical screening revealed that out of the thirteen constituents screened for, n-hexane extract contained seven components, including flavonoids, coumarin, steroid, glycosides, triterpenes, terpenoids, and alkaloids. In contrast, the ethyl acetate extract contains saponin, flavonoids, coumarin, steroid, glycosides, triterpenes, terpenoids, and alkaloids. The HPLC chromatogram of n-Hexane and ethyl acetate extracts of E. lateriflora detected numerous unidentified compounds along with a potential antimicrobial compound identified as caffeic acid. The low MIC (6.25 - 50 mg/mL), shown by the n-hexane extract signified a greater antimicrobial activity than ethyl acetate extract. This was further implicated by the varying concentrations levels, rather than the strain-dependent zone of inhibitions obtained. The highest diameter of zone of inhibition (14.23 mm) was obtained at 100 mg/mL by n-hexane extract against E. coli and S. aureus, respectively, while the lowest zone of inhibition (6.00 mm) was obtained by n-hexane at 25 mg/mL concentrated tested against S. aureus. However, the diameter of the zone of inhibition of Ciprofloxacin (50 mg/mL) ranged between 10-16 mm for E. coli and 6-10 mm for S. aureus. At the same time, 14.00 mm was obtained by itraconazole (antifungal agent) against C. albicans. Thus, this study shows that E. lateriflora harbors active compounds and supports the claim that its extract may be effective against infections caused by the test organisms, as practiced for years among rural dwellers in Nigeria.

Common Fixed Point of a Finite-step Iteration Algorithm Under Total Asymptotically Quasi-nonexpansive Maps
...Show More Authors

      Throughout this paper, a generic iteration algorithm for a finite family of total asymptotically quasi-nonexpansive maps in uniformly convex Banach space is suggested. As well as weak / strong convergence theorems of this algorithm to a common fixed point are established. Finally, illustrative numerical example by using Matlab is presented.

The Biological Effect of ZnO Nanoparticles Produced by Using Petroselinum crispum Extract against Candida spp
...Show More Authors

Non-thermal or cold plasma create many reactive species and charged particles when brought into contact with plant extracts. The major constituents involve reactive oxygen species, reactive nitrogen species and plasma ultra-violets. These species can be used to synthesize biologically important nanoparticles. The current study addressed the effect of the green method-based preparation approach on the volumetric analysis of Zn nanoparticles. Under different operating conditions, the traditional thermal method and the microwave method as well as the plasma generation in dielectric barrier discharge reactor were adopted as a preparation approach in this study. The results generally show that the type of method used plays an important role in d

Photosensitivity of Nb2O5/Si Thin Films Produced via DC Reactive Sputtering at Different Substrate Temperatures
...Show More Authors

This study thoroughly investigates the potential of niobium oxide (Nb2O5) thin films as UV-A photodetectors. The films were precisely fabricated using dc reactive magnetron sputtering on Si(100) and quartz substrates, maintaining a consistent power output of 50W while varying substrate temperatures. The dominant presence of hexagonal crystal structure Nb2O5 in the films was confirmed. An increased particle diameter at 150°C substrate temperature and a reduced Nb content at higher substrate temperatures were revealed. A distinct band gap with high UV sensitivity at 350 nm was determined. Remarkably, films sputtered using 50W displayed the highest photosensitivity at 514.89%. These outstanding optoelectronic properties highlight Nb2O5 thin f

MCD (LOS MARCADORES DISCURSIVOS) The pragmatic analysis of discourse markers (The argumentative texts of the ABC newspaper as a model): El análisis pragmático de los marcadores discursivos (Los textos argumentativos del periódico ABC como modelo)
...Show More Authors

When writing a text, such as a newspaper article, various types of discourse markers are frequently used to group sentences into paragraphs and parts in order to establish a discourse with certain functions, such as coordination, orientation, emphasizing the concepts presented, etc. It should also be noted that this type of mark exists in both written and spoken language. Therefore, it is convenient to dedicate a chapter to these linguistic elements to clarify their use and their classification, which is mainly based on Jose Portolés (2001), as well as the main features, specifically their features (prosodic, morphological, semantic and pragmatic).

Fixed Point Theorem for Set Valued Mapping with Rational Condition
...Show More Authors

In this paper, we generalized the principle of Banach contractive to the relative formula and then used this formula to prove that the set valued mapping has a fixed point in a complete partial metric space. We also showed that the set-valued mapping can have a fixed point in a complete partial metric space without satisfying the contraction condition. Additionally, we justified an example for our proof.

GEOMETRIC NONLINEAR TIME DOMAIN SPECTRALMATCHING SEISMIC ANALYSIS OF BASE ISOLATED HIGHRISE BUILDINGS INCLUDING P-DELTA EFFECT
...Show More Authors

Time-domain spectral matching commonly used to define seismic inputs to dynamic analysis in terms of acceleration time history compatible with a specific target response spectrum is used in this study to investigate the second-order geometric effect of P-delta on the seismic response of base-isolated high-rise buildings. A synthetic time series is generated by adjusting reference time series that consist of available readings from a past earthquake of the 1940 El Centro earthquake adopted as an initial time series. The superstructure of a 20-story base isolated building is represented by a 3-D finite element model using ETABS software. The results of the base isolated building show that base isolation technique significantly reduces inter-s
