GRAMMATICAL GENDER AND OBJECT PERCEPTION OF ENGLISH-ARABIC BILINGUAL CHILDREN

The main purpose of this study was to investigate the possible effects of grammatical gender on objects perception. It examined how Arabic grammatical gender system can affect objects’ perception of Arabic native speakers. The sample of the study consisted of ninety eight English-Arabic bilingual children. A cognitive experiment was carried out in order to investigate gender effects (picture similarity task followed by confidence scale). The result of this study revealed that there was no effect of Arabic grammatical gender on object perception of the participants. The study revealed that Arabic-English bilingual speakers end up thinking about objects which are grammatical gender in Arabic as neutral depending on the object’s grammatical gender in their second language.  Article visualizations

Olive Leaf Extracts for a Green Synthesis of Silver-Functionalized Multi-Walled Carbon Nanotubes

Green biosynthesis, one of the most dependable and cost-effective methods for producing carbon nanotubes, was used to synthesize nonhazardous silver-functionalized multi-walled carbon nanotubes (SFMWCNTs) successfully. It has been shown that the water-soluble organic materials present in the olive oil plant play a vital role in converting silver ions into silver nanoparticles (Ag-NPs). Olive-leaf extracts contain medicinal properties and combining these extracts with Ag-NPs is often a viable option for enhancing drug delivery; thus, this possibility was employed for in vitro treating cancer cells as a proof of concept. In this study, the green technique for preparing SFMWCNTs composites using plant extracts was followed. This process yielded various compounds, the most important of which were Hydroxytyrosol, Tyrosol, and Oleuropein. Subsequently, a thin film was fabricated from the extract, resulting in a natural polymer. The obtained nanomaterials have an absorption peak of 419 nm in their UV–Vis. spectra. SEM and EDS were also used to investigate the SFMWCNT nanocomposites’ morphology simultaneously. Moreover, the MTT assay was used to evaluate the ability of SFMWCNTs to suppress cancer cell viability on different cancer cell lines, MCF7 (human breast adenocarcinoma), HepG2 (human hepatocellular carcinoma), and SW620 (human colorectal cancer). Using varying doses of SFMWCNT resulted in the most significant cell viability inhibition, indicating the good sensitivity of SFMWCNTs for treating cancer cells. It was found that performing olive-leaf extraction at a low temperature in an ice bath leads to superior results, and the developed SFMWCNT nanocomposites could be potential treatment options for in vitro cancer cells
