Cu-Doped TiO2 Nanopowders Synthesized by Sonochemical-assisted Process (Serbuk Nano Cu-terdop TiO2 Disediakan Melalui Proses Sonokimia Terbantu)

Cu-doped TiO2 nanopowders were prepared by sonochemical-assisted process via a precursor solution of titanium isopropoxide, copper nitrate trihydrate and sodium hydroxide in the presence of polyvinyl alcohol in combination with calcinations process. The as-synthesized products were calcined at various temperatures ranging from 500-1000°C. The physical microstructures, morphologies and chemical ...

Using Concept Mapping and Mind Mapping in Descriptive and Narrative Writing Classes

This study was an attempt to investigate the comparative impact of concept map and mind map instruc- tion on EFL learners’ descriptive and narrative writing. To fulfill this purpose, 60 intermediate EFL learners were selected from among a total number of 100 through their performance on a pretest, i.e., a piloted sample Cambridge Preliminary English Test (PET).

Mapping the mind

Modular mind mapping

Concept maps, or mind maps as learning tools mirror the knowledge constructed through observation of events or objects in relation to the concepts already known. Different types of computer based concept mapping tools allow various forms of expressions and the versatility of some special tools promote their use from providing course maps for users to adaptations of learners knowledge maps. Modu...

Cytotoxic effect of γ-sitosterol from Kejibeling (Strobilanthes crispus) and its mechanism of action towards c-myc gene expression and apoptotic pathway

Metode: Penelitian in vitro ini menggunakan kultur sel kanker kolon manusia (Caco-2), sel kanker hepar manusia (HepG2), sel kanker payudara tergantung hormon (MCF7) dan kultur sel normal hepar manusia (Chang Liver). Efek sitotoksik diukur melalui uji MTT melalui penentuan kadar yang membunuh 50% sel (IC50). Mekanisme sitotoksik dipelajari dengan menentukan pengaruh penambahan γ-sitosterol pada ...
