Here, we synthesize zwitterionic polymer brushes on polyester fabrics by atom transfer radical polymerization (ATRP) after a prefunctionalization step involving an aminolysis reaction with ethylenediamine. Aminolysis is an easy method to achieve homogeneous distributions of functional groups on polyester fibers (PET) fabrics. Varying the polymerization time and the prefunctionalization conditions of the reaction, it is possible to tune the amount of water retained over the surface and study its effect on protein adhesion. This study revealed that the polymerization time plays a major role in preventing protein adhesion on the PET surface.

This research is experimental research. The population in this study was all students of Class VIII SMP Negeri 1 Sumarorong. Samples of 42 people consisting of class VIII A of 24 people and class VIII B as many as 18 people taken in random sampling. In this study used test instrument study results, learning model implementation sheet, and student activity sheet. The Data obtained is analyzed using descriptive statistical analysis and inferential statistical analysis. Based on data analysis results, both groups are normal and homogeneous distributions, so that hypothesis testing is performed using Test-t statistics. Based on the test-T statistics obtained: 1) The median value of the experimental class pretests 54.94 while the control class is 53.80, and the average Postest experimental class is 78.17, while the control class is 68. 2) for the implementation of the Inkuiri model's execution sheet after analyzed was obtained an average of 94%, as well as the activity sheet of students for the experimental class obtained 61% while the control class was 38%. and test-T acquired significant 0.024 < 0.05 This indicates that H0 was rejected and H1 received. Thus, it can be concluded that the Learning model inquiry affect the outcome of mathematics for students of class VIII SMP Negeri 1 sumarorong.

Here, the propagation of vector-borne diseases is modeled by using a probabilistic cellular automaton. Numerical simulations considering distinct spatial distributions and time variations of the vector abundance are performed, in order to investigate their impacts on the number of infected individuals of the host population. The main conclusion is as follows: in the clustered distributions, the prevalence is lower, but the eradication is more difficult to be achieved, as compared to homogeneous distributions. This result can be relevant in the implementation of preventive surveillance measures.
