AbstrakKalsium merupakan mikronutrien penting dalam ASI. Jumlahnya yang sedikit dan dapat berkurang karena preparasi sampel menjadi sebab perlunya dilakukan uji presisi agar diketahui ketelitian hasil laboratorium. Tujuan Penelitian ini adalah mengetahui pengukuran kalsium pada Air Susu Ibu (ASI). Metode digunakan penelitian eksperimen menggunakan alat Spektrofotometer Serapan Atom (SSA). dimul...

Microteaching lesson study, that is a variation of study applied by student teachers in microteaching course, provides the environment for EFL to collaborate, engage, and reflect on their ideas, beliefs, teaching experiences. Such condition fertile ground enables teachers' beliefs language learning change. Recent studies show some education programs have changed teachers. However, no discussed ...

The fabrication, optimization and validation of measurement using a modified carbon paste electrode (CPE) with dibenzo-18-crown-6 were carried out for the determination paracetamol in commercial products. pH, concentration paste, scan rate parameters optimized. Validation was observed from linear range, LoD, LoQ, precision, percentage recovery. result showed that optimum pH at 2, 0.6%, rates 35...

This study aimed to find out the level of students' self-confidence and willingness communicate in English. Furthermore, main purpose this was correlation between their The researcher adapted questionnaire from Park Lee (2004) cited Ningsi (2020).

Slicing is a widely-used technique with applications in e.g. compiler technology and software security. Thus verification of algorithms in these areas is often based on the correctness of slicing, which should ideally be proven independent of concrete programming languages and with the help of well-known verifying techniques such as proof assistants. After verifying static intraprocedural and d...

• Dopamine (3,4 dihydroxyphenylethylamine), a biochemical precursor of levarterenol and epinephrine, has been shown in previous studies in intact animals to be pressor in the eat, depressor in the rabbit and guinea pig, and to have a variable, but predominantly pressor effect in the intact dog. Dopamine has been shown by Fowler, Shabetai, and Holmes to produce contraction of the rabbit aortic s...

Social stress models are the predominant theoretical frame for studies of the relationship between social statuses and mental health (Dressler, Oths, & Gravlee, 2005; Horwitz, 1999). These models propose that prejudice, discrimination and related social ills exert an added burden on socially disadvantaged populations (populations subjected to stigma, prejudice and discrimination) that can gener...

Taxol®, an antitumor drug with significant activity, is the first microtubule stabilizing agent described in the literature. This short review of the mechanism of action of Taxol® emphasizes the research done in the Horwitz' laboratory. It discusses the contribution of photoaffinity labeled analogues of Taxol® toward our understanding of the binding site of the drug on the microtubule. The impo...
