1. Investigation of PRL-RsaI and HaeIII gene polymorphisms in Anatolian water buffaloes bred by using PCR-RFLP method
ABSTRACT The objective of this study was to investigate polymorphisms both in exons 1 and 3 of prolactin (PRL) gene for milk productivity of Anatolian water buffalo breed in Sivas province in Turkey. Blood samples were collected from 129 male and female water buffaloes and DNA was isolated by using phenol/chloroform method. Samples of DNA were amplified and

2. In Situ Photoactivated Plasmonic Ag3PO4@silver as a Stable Catalyst With Enhanced Photocatalytic Activity Under Visible Light
Silver orthophosphate (Ag3PO4) had been reported as an excellent candidate to split water or decompose pollutants with high efficiency in visible light region, yet is not stable due to the reduction of silver ion. In this work, an easy-fabricated method (in situ photoinduced reduction) was provided to enhance the stability of Ag3PO4 for its possible applicat

3. Desenvolvimento e aplicação de técnicas miniaturizadas de preparo de amostra na determinação de fármacos no ambiente / Development and application of microextraction sample preparation techniques to determine pharmaceutical drugs in the environment
The occurrence of pharmaceutical drugs in the environment is a worldwide problem caused by the genotoxicity and ecotoxicity activities of those compounds. Water is one of most used natural resource in human activities which explain the presence of emerging contaminants. Those compounds affect not only humans but also aquatic animals that spend the whole life

4. PreparaÃÃo e utilizaÃÃo de uma argila organofÃlica como adsorvente de Fenol
This research had as main objective the attainment of organophilic clay with capacity to promote the separation of phenol, found in effluent the watery ones of petrochemical industries. The experimental procedure objectifying the attainment of the organoclay was initiated by a treatment of natural clay with sodium carbonate. This treatment had as goal to int

5. Separation of binary mixtures by pervaporation and reverse osmosis / Separação de misturas binarias por pervaporação e osmose inversa
In this work, the modelling and simulation of pervaporation and reverse osmosis processes for binary mixtures were carried out. The development of prediction methodologies for process variables of pervaporation and reverse osmosis without the necessity of experimental data was the general guideline followed; the experimental data used in these methodologies

6. Experimental determination and thermodynamic modeling of equilibrium phase data of binaries and ternary mixtures containing acetone, water and cumene / Determinação experimental e modelagem termodinamica de dados de equilíbrio de fases de misturas binarias e ternaria contendo acetona, agua e cumeno
On projecting separation processes it is essential the knowledge of the behavior of the phases in equilibrium. The present work involved the study of the phase equilibrium of mixtures containing acetone, water and cumene, which are very important in the phenol industry. The components water and cumene are partially miscible, and in the distillation of the mi

7. Extração, purificação e caracterização de polissacarídeos da biomassa do fungo ascomiceto Botryosphaeria rhodina MAMB-05
The composition of the polysaccharides constituting the biomass of the ascomyceteous fungus, Botryosphaeria rhodina MAMB-05, cultivated on glucose as carbon source was investigated following separation of the exopolysaccharides (EPS). Fungal mycelial biomass was exhaustingly washed with water at room temperature until no residual sugars could be detected (ph

8. Desenvolvimento de modelagens de não equilibrio para caracterização e aplicação em simulação de colunas de destilação complexas / Development of nonequilibrium models for characterization and application in simulation of complex distillation columns
Distillation is, certainly, the most applied process in the separation of liquid mixtures. Although this is a very known unit operation, still nowadays some difficulties persist in the proposal of appropriate distillation schemes. Thus, the objective of this work was to apply more realistic models in the characterization of mixtures and in the simulation of

9. Separation process of complex mistures / Projeto de processos de separação de sistemas complexos
The separation process of homogeneous and non ideal mixtures is a common problem in chemical industries. The complex mixture separations may happen at low pressure to prevent thermal degradation or using reactive distillation to eliminate existing azeotropes and/or in order to increase the rei ative volatility of the components to be separated. Reactive dist

10. Experimental study and thermodynamic modeling of phase equilibrium (liquid-liquid and liquid-vapor) of systems regarding phenol industry / Estudo Experimental e modelagem termodinamica do equilibrio de fases (liquido-liquido e liquido-vapor) de sistemas de interesse da industria de fenol
Studies concerning physical and chemical phenomena are very important for the chemical industry, form the early stages of design up to full plant operation. Among the many units that make up a chemical plant, the last steps of separation and purification stands as the most expensive. Phenol, used to produce resins as well as other products, is an important f

12. Desenvolvimento de um programa para geração de mapas de curvas residuais e aplicação a processos de destilação azeotropica e extrativa
Despite the development of new separation processes, the predominant unit operation used in chemical industries is, still, distillation, especially for large-scale separation of non-ideal mixtures. Many papers have dedicated special attention to the study of azeotropic mixtures, looking for the development of design and synthesis tools. Residue curve maps pl
