Computer based systems, methods, software and databases are presented in which correlations between web item preferences and pangenetic attributes of individuals are used for pangenetic based web item recommendation in which a user can request and receive personalized online recommendations of web items that are based on the user’s pangenetic makeup. Then, the positioning spring releases energy to rotate the locking element in an opposite direction, and thus the protruding pillar is moved to a guiding concave to be accommodated and fixed. The transmission is protected from respective peak loads applied on the front wheel and the rear wheel. User selection of a particular video mosaic then initiates a playback of corresponding video frames. The heat spreading cap comprises a single high-K graphite layer supported by a copper frame for increased stability and reduced thermal warpage during handling and operation while minimizing thermal penalty by reducing the amount of material having a relatively low heat conductivity that is needed in conventional heat spreading caps. The flame retardants exhibit high compatibility with textile materials and are stable in aqueous solutions.
