Prior qualitative descriptions have claimed coordinated movements of the limbs in a manner similar to tetrapod vertebrates, but this has not been evaluated quantitatively. It is uncertain whether the ring-shaped nervous system, which lacks an ana...

A fact crudely recognised by the inhabitants of the many countries through which Arab traders travel, would lead one to expect that their mother country should prove no exception to the rule.

متن کاملBerberine in Malaria. A Preliminary Note
tj ^Kopra (1933) has pointed out that berbenne, .^J^active principle of berberine-containing plants, has some remarkable properties in its behaviour towards the parasites of malaria. Its sulphate has been found to liberate the parasites into the peripheral circulation from the internal organs, so that, whereas blood films taken before the administration of berberine are negative, those taken af...
متن کاملA New Approach in Preliminary Design of Closed Loop Solar Thermal Systems (RESEARCH NOTE)
In this paper, a model for closed loop solar system is presented and an attempt is made to generalize the model to be utilized for primary design of any solar active thermal system. This model may be used for systems in which gas or a liquid are fluids that flow. Two new parameters, namely, the system heat delivery factor and the system heat absorption factor are introduced in the model. These ...
متن کاملOn the Popularity of GitHub Applications: A Preliminary Note
GitHub is the world’s largest collection of open source software. Therefore, it is important both to software developers and users to compare and track the popularity of GitHub repositories. In this paper, we propose a framework to assess the popularity of GitHub software. We also propose a set of popularity growth patterns, which describe the evolution of the number of stars of a system over t...
