1. MAXIMIZATION OF ESSENTIAL OIL ANTIOXIDANT CAPACITY VIA STAR ANISE HYDRODISTILLATION
Abstract Chinese star anise essential oil (EO) is prized for its pleasant aroma and mainly due to its antioxidant capacity (AC), which can combat cancer and treat neurodegenerative diseases. This study shows the innovative approach of optimizing not only EO yield, but also to therapeutic activity. The product obtained follows the principle of the Pure Food a

2. OPTIMIZATION OF HIGH-CONCENTRATION TRANS-ANETHOLE PRODUCTION THROUGH HYDRODISTILLATION OF STAR ANISE
Abstract Illicium verum Hook essential oil (EO) is composed mainly of trans-anethole (TA), which has therapeutic potential. The extraction is usually by hydrodistillation, taking long hours, leaving the process costly and product with lower quality. Thus, the present study sought to optimize dehydrated fruit fragmentation by Box-Wilson central composite desi

3. Development of sunscreen products containing passion fruit seed extract
Abstract Application of sunscreen is the most established method of protecting skin from premature aging and photoaging. In this study, the passion fruit seed extract, enriched with biologically beneficial phenolics, was formulated into sun-protective makeup product. The UVB protection of concealer mousse was found have twofold higher sun protection factor (

4. Drying of α-amylase by spray drying and freeze-drying - a comparative study
This study is aimed at comparing two traditional methods of drying of enzymes and at verifying the efficiency of each one and their advantages and disadvantages. The experiments were performed with a laboratory spray dryer and freeze-dryer using α-amylase as the model enzyme. An experimental design in star revealed that spray drying is mainly influenced by

7. Quantization of non-Lagrangian systems and noncommutative quantum mechanics / Quantização de sistemas não-Lagrangianos e mecânica quântica não-comutativa
Nesta tese apresentamos três problemas interligados: a quântização de teorias não-Lagrangianos, a mecânica quântica não-comutativa (MQNC) e a construção do produto estrela atravéz do ordenamento de Weyl. No contexto do primeiro problema foi elaborada uma abordagem da quantização canônica de sistemas com as equações de movimento não-Lagrangia

11. The classical and commutative limits of noncommutative quantum mechanics: a superstar * Wigner-Moyal equation
We are interested in the similarities and differences between the quantum-classical (Q-C) and the noncommutative-commutative (NC-Com) correspondences. As one useful platform to address this issue we derive the superstar Wigner-Moyal equation for noncommutative quantum mechanics (NCQM). A superstar *-product combines the usual phase space * star and the nonco

12. Analise do processo de extrusão na industria de "PET-FOOD" para a aplicação de tecnicas de controle avançado / Review of the extrusion industry in the "PET-FOOD" for the application of advanced techniques of control
The present study informs about the main features of extrusion control processes, based on product-wet density and moisture. To comprehend the study, some background of the classic control theory is provided. The process complexity, provided by formation of a bio-polymer from carbohydrate-lipid-protein raw materials, requires analysis using statistical conce
