Tea tree oil (TTO) merupakan minyak esensial yang berasal dari Melaleuca alternifolia mengandung terpinen-4-ol. TTO memiliki aktivitas sebagai antimikroba. gel bersifat hidrofobik sehingga membutuhkan sistem penghantaran untuk bisa berpenetrasi melewati stratum korneum. Tujuan penelitian ini adalah membuat nanoemulgel TTO, menggunakan Carbopol 940 dan Tween 80 digunakan surfaktan. Optimasi form...

solid lipid nanoparticles of atovaquone (atq-sln) were prepared by high shearhomogenization method using tripalmitin, trilaurin, and compritol 888 ato as the lipidmatrices and phospholipon 90h, tween 80, and poloxamer 188 as the surfactants. optimizationof the formulations was conducted using 6 sets of 24 full-factorial design based on fourindependent variables that were the number of homogeniz...

This chapter focuses on stated preferences obtained from discrete choice experiments (DCEs also known as SPDCEs), as opposed to data that reflect real market choices (revealed preferences (RP) as discussed in Chapter 9). DCEs try to simulate the essential elements of real market options that consumers might face in the future. Unlike real market choice data, DCEs rely on constructed markets in ...

full factorial experimental design (23) for the evaluation of slurry ethylene polymerization in the presence of an industrial ticl4/mgcl2 ziegler-natta catalyst was employed. the following parameters were used as independentvariables: al/ti molar ratio, reaction temperature and hydrogen partial pressure. the total polymerization pressure was 9 bar. catalyst activity, mfi (melt flow index) and m...

OBJECTIVE To translate the Perceived Stress Scale into Brazilian Portuguese, and to assess its validity for measuring perceived stress of Brazilian elderly. METHODS The scale was translated and tested in its full version including 14 questions and in a shortened version including ten questions. The whole translation process consisted of translation, back-translation and committee review. The ...

OBJECTIVE To examine the factor structure of the 144-item Chinese version of the Temperament and Character Inventory (TCI) and its association with age and gender in a large non-clinical population. METHOD We recruited 1966 non-clinical participants in China who completed the TCI Chinese version. They were randomly divided into two independent samples. One sample (n=983) was used for explorat...
