2. Alcoholmeter as a Simple and Accessible Way for Ethanol Determination in Alcohol-Based Hand Sanitizers
Expensive and complex methodologies are available to determine the ethanol concentration in alcohol gel samples. The aim of this article was to demonstrate that alcoholmeter could be used as an alternative method to determine ethanol in gel formulations. Alcohol gel samples were produced using: hydroxypropylmethylcellulose (HPMC), hydroxyethylcellulose (HEC)

3. Using static, kinetic and metal mobility procedures to evaluate possibilities of coal waste land disposal at Moatize Mine, Mozambique
Abstract Coal mine waste rocks produced during mining and beneficiation can affect the environment due to land degradation and acid mine drainage generation. However, proper characterization and treatment of mineral processing wastes creates options for safe disposal, enhancing the environmental performance. The aim of this study was to use static and kineti

4. Lutein as a functional ingredient in sheep milk yogurt: development, characterization and extraction recovery
Abstract The research aimed to evaluate the behavior of different concentrations of lutein added in sheep milk yogurt. The work verified the effect on acidity, pH, color, lutein degradation, and recovery during storage. Different added lutein concentration into yogurt were compared: 0.00 mg; 3.0 mg; 3.45 mg; and 3.9 mg (·100 mL-1). Analyzes were performed o

5. Liquid whey protein concentrates as primary raw material for acid dairy gels
Abstract The replacement of dehydrated products such as whey protein concentrates and isolates (WPC and WPI) by liquid whey protein concentrates (LWPC) obtained by ultrafiltration can be an excellent alternative for the production of innovative dairy products. Thus, the aim of this work is to study the gelation properties of LWPC as raw material for acid-ind

8. The Role of ß-Mannanase (Hemicell) in Improving Poultry Productivity, Health and Environment
ABSTRACT The poultry nutritionists constantly attempt to identify and alleviate the factors responsible for adverse effects on nutrient utilization and production performance in avian species, which are necessary for successful productivity of poultry. Enhanced feed utilization can reduce levels of some nutrients in the diet with concomitant mitigation in nu

10. Valorização de resíduos de ágata em argamassas e concretos: avaliação do ciclo de vida
RESUMO O uso de resíduos oriundos do processo de beneficiamento de ágata (pó de ágata) em argamassas e concretos de cimento Portland é viável tecnicamente por suas propriedades mecânicas e de durabilidade. Porém, não existem pesquisas que avaliem o perfil ambiental dos materiais produzidos. O presente estudo visa avaliar os impactos ambientais poten

11. Water acidification causes death of marine ornamental fish (Perciformes: Pomacentridae) during transport: contributing to the conservation of wild populations
ABSTRACT Pomacentridae is a common family in the aquarium fish trade. Most species are harvested from nature. Here we evaluate the following water parameters in the pomacentrid sergeant major, Abudefduf saxatilis (Linnaeus, 1758), to assess their stress level during a 24, 48, and 72 hours transport: dissolved oxygen (DO), total ammonia, and pH. In addition,
