Abstract Background Cancer is a significant public health problem worldwide and constitutes the second leading cause of death after cardiovascular disease. This study was thus designed to identify new natural compounds from Malagasy medicinal plants traditionally used treat cancer. Methods In silico analyses by molecular docking model ligand–protein interactions, SwissADME ADMET webservers establish pharmacokinetic profile four investigated in interaction with angiogenesis target protein...
The current study focuses on alkali-assisted roasting, dissolution, and recovery of mixed oxides niobium (Nb) tantalum (Ta) from a ferro-columbite concentrate collected Jos Plateau in Nigeria. Alkali-assisted roasting water-based leaching to extract Nb Ta using guanidine carbonate salt were adopted for sustainable extraction. was roasted with caustic potash (KOH) as flux at optimized conditions (250 °C, 100% mass flux-to-concentrate ratio, 1 h) leached water. This resulted dissolution 97-96%...
In this work, mineralogical and physical characterization of low-grade tantalum-tin ore-samples from Ntunga Kamonyi Rwanda were carried out using various techniques. The classified as non-radioactive ores they contained less than 0.1% Ta2O5 Nb2O5, the percentage radioactive oxides below critical value 0.5%. characteristic elements associated with tantalum detected quantified by Inductively Coupled Plasma-Optical Emission Spectroscopy expressed for their natural occurrence included Ta2O5,...
The current study explores students’ reflection and conception towards the utilization of web-based discussion in teaching learning organic chemistry. seeks to investigate influence on performance A total 153 senior three students were involved study. mixed research approach was used collect data whereby an achievement test quantitative while open-ended questionnaire qualitative data. paired t-test analyze interpretive analysis results revealed that a is powerful tool enhances chemistry (p˂...
This study aimed to investigate the use of formative assessment rubrics for supporting learning organic chemistry in secondary schools Rwanda.A mixed research approach was used collect and analyze data.The target population 210 senior five students 15 teachers.However, 140 10 teachers were purposively selected participate study.The qualitative data obtained from interview while quantitative survey questionnaire.The analyzed by discourse interpretive approaches checked descriptive statistics.
