Both primed in situ labeling (PRINS) and peptide nucleic acid (PNA) technologies have emerged as research techniques, but they have quickly evolved to applications in biological diagnosis assays. The two procedures present several features (specificity, discriminating ability, rapidity) that make them very attractive for cytogenetic purposes. The combined use of PRINS and PNA for in situ chromo...

The study estimated the difficulty, discrimination, and vulnerability to guessing 2016 National Examination Council (NECO) Mathematics multiple-choice test items. employed an ex-post facto design with 276,338 samples. research instruments used for were Optical Marks Record Sheets NECO June/July objectives responses of testees scored dichotomously. Data collected calibrated using four parameters...

Three new distance—based topological indices are described; two of them, D and D1 (mean distance topological indices, for any graphs, and for acyclic graphs, respectively) have a modest discriminating ability but may be useful for correlations, e. g. with octane numbers. The third index, J (average distance sum connectivity) is the least degenerate single topological index proposed till now. Th...

This paper proposes color invariant moment features based on color clustering. Similarity measure method based on the color invariant moment descriptors is given. This method is applied in a practical application system. The experimental result shows that, the proposed feature has both a wider and steadier invariant and a stronger ability in color based image region similarity discriminating th...

This study aims to find out the procedure and assess quality of developing test instruments measure students' mathematical connection abilities. Students seemed lacking in answering questions develop their ability, therefore it is necessary practice research a development under formative model that conducted through four sreps. The data collection this were validation sheets instruments. subjec...
