1. MODELO ESTOCÁSTICO PARA A EXCLUSÃO PELO TAMANHO DURANTE O TRANSPORTE DE SUSPENSÕES PARTICULADAS EM MEIOS POROSOS / STOCHASTIC MODEL FOR SIZE EXCLUSION MECHANISM DURING SUSPENDED PARTICLE SUSPENSION TRANSPORT IN POROUS MEDIUM
Deep bed filtration of water with particles occurs in several industrial and environmental processes like water filtration and soil contamination. In petroleum industry, deep bed filtration occurs near to injection wells during water injection, causing injectivity reduction. It also takes place during well drilling, sand production control, produced water di

2. Modelling and simulation of the biological and physical processes of slow sand filtration
Slow sand filtration (SSF) is the earliest form of engineered potable water treatment and remains one of the most efficient processes for improving the physical, biological and chemical quality of water. However, whilst widely used throughout the world, knowledge of the filtration mechanisms remains limited. This is important in understanding and managing th

3. Mapping leptin-interacting sites in recombinant leptin-binding domain (LBD) subcloned from chicken leptin receptor
The binding domain of the chicken leptin receptor [chLBD (chicken leptin-binding domain)], subcloned from the full-size chicken leptin receptor and prepared in an Escherichia coli system, was subjected to site-directed mutagenesis to identify the amino acids involved in leptin binding. A total of 22 electrophoretically pure, >90% monomer-containing mutants w

4. FliG and FliM distribution in the Salmonella typhimurium cell and flagellar basal bodies.
Salmonella typhimurium FliG and FliM are two of three proteins known to be necessary for flagellar morphogenesis as well as energization and switching of flagellar rotation. We have determined FliG and FliM levels in cellular fractions and in extended flagellar basal bodies, using antibodies raised against the purified proteins. Both proteins were found pred
