A Relay Race on the Evolutionary Adaptation Spectrum
Adaptation is the process in which organisms improve their fitness by changing their phenotype using genetic or non-genetic mechanisms. The adaptation toolbox consists of varied molecular and genetic means that we posit span an almost continuous "adaptation spectrum." Different adaptations are characterized by the time needed for organisms to attain them and by their duration. We suggest that o...
متن کاملBata Positioning System - A real time tracking system for the world's largest relay race
Modern technology makes it possible to develop applications that determine the position of any object. Using affordable off-the-shelf components combined with internet-based applications, we developed the Bata Positioning System (BPS), a real time system for tracking moving objects. It has a focus on accessibility to the user and system scalability. BPS combines the power and flexibility of sat...
متن کاملNutritional behavior of cyclists during a 24-hour team relay race: a field study report
BACKGROUND Information about behavior of energy intake in ultra-endurance cyclists during a 24-hour team relay race is scarce. The nutritional strategy during such an event is an important factor which athletes should plan carefully before the race. The purpose of this study was to examine and compare the nutritional intake of ultra-endurance cyclists during a 24-hour team relay race with the c...
متن کاملCopper-catalyzed N-alkylation of amides and amines with alcohols employing the aerobic relay race methodology.
By employing aerobic oxidation to aldehydes as a more effective alcohol activation strategy, we developed a green Cu-catalyzed N-alkylation method for various amides and amines with alcohols. This reaction is more advantageous than the literature methods for it uses a ligand-free copper catalyst, can be readily carried out under milder aerobic conditions and generates water as the only byproduc...
متن کاملRelay race of practice: integrating technological tools into teaching and learning scenarios
Even though integrating technological tools into teaching and learning scenarios is an agreed upon goal it is still far from being fully implemented. This study examines a process of integration of a technological tool, to which a group of teachers participated. The technological tool was developed to enhance dialogism and argumentation, in one Grade 9 class. The question we focused on concerns...
