The present studies were focused on the formation and characterization of sterically stabilized archaeosomes made from a synthetic PEGylated archaeal lipid. In a first step, a synthetic archaeal tetraether bipolar lipid was functionalized with a poly(ethylene glycol), PEG, and (PEG45-Tetraether) with the aim of coating the archaeosome surface with a sterically stabilizing hydrophilic polymer. In a second step, Egg-PC/PEG45-Tetraether (90/10 wt%) archaeosomes were prepared, and their physicochemical characteristics were determined by dynamic light scattering (size, polydispersity), cryo-TEM (morphology), and by high-performance thin layer chromatography (lipid composition), in comparison with standard Egg-PC/PEG45-DSPE formulations. Further, a fluorescent dye, the carboxyfluorescein, was encapsulated into the prepared archaeosomes in order to evaluate the potential of such nanostructures as drug carriers. Release studies have shown that the stability of Egg-PC/PEG45-Tetraether-based archaeosomes is significantly higher at 37∘C than the one of Egg-PC/PEG45-DSPE-based liposomes, as evidenced by the slower release of the dye encapsulated into PEGylated archaeosomes. This enhanced stability could be related to the membrane spanning properties of the archaeal bipolar lipid as already described with natural or synthetic tetraether lipids.

This research activity is development research using the ADDIE development model and the Tessmer evaluation method. The development stages include analysis, design, development, implementation, and evaluation. The prototype evaluation was carried out in stages: self-evaluation, expert reviews, one-to-one evaluation, small group evaluation, and field test evaluation. The results showed that the HOTS-based 2013 curriculum assessment instrument developed was declared valid, with a percentage of 89.5%. The trial results in the one to one and small group stages showed that the assessment instrument (HOTS questions) had a very good level of practicality, namely 84.3% for the one to one stage, and 83.2% for the small group stage. The effectiveness of the HOTS-based 2013 curriculum assessment instrument is at a low level, with an average score of 50. This means that the HOTS questions developed are still not effective in helping students think at higher levels, in this case, the ability to analyze, evaluate and create. This is as a note for researchers to review by carrying out further research.

<p>In order to recruit and train students to participate in Olympiads of Informatics (OI), the Olympic Programming Project group of IFPB Campina Grande Campus (POP-CG) has started to perform OI simulations. For this purpose, an online judge was used to create programming competitions, ForCode (https://github.com/ LADOSSIFPB/POP-Judge). Mining students’ performance data (number of submissions and hits, programming language used) from the code repository generated by ForCode may reveal what programming skills should be improved. Associating this information with holistic data about students (eg.: schooling, socioeconomic status, and so on) may indicate which factors impact (positively or negatively) on the performance of these students. In this article, we joined performance data of 47 students participating in the OI simulation, conducted in November 2015, to holistic data collected from the IFPB academic management system: the year of schooling. Then, we evaluated statistically the relation between the performance’s simulated OI with year of schooling. The results point out that, regardless of programming language used, the “trial and error” learning strategy is the one that prevails among the students with the best performance. When considering schooling, the average score of the students in the 2nd year is 15% higher than the average of the students in the 1st year, while the average score of the students in the 4th year is 78% higher than those of the students of the 2nd year 105% higher than those obtained in the 1st year</p>
