Governance of both poles.
AT THE END OF THIS MONTH, THE ANTARCTIC TREATY SUMMIT IN WASHINGTON, DC, WILL CELEBRATE the 50th anniversary of an international agreement that has been centered around science, promoting cooperation to manage nearly 10% of Earth for peaceful purposes since 1 December 1959 (see www.atsummit50.aq). As the world moves toward negotiating effective policies related to climate change, lessons from t...
متن کاملInformation Security governance: COBIT or ISO 17799 or both?
This paper investigates the coexistence of and complementary use of COBIT and ISO 17799 as reference frameworks for Information Security governance. The investigation is based on a mapping between COBIT and ISO 17799 which became available in 2004, and provides a level of 'synchronization' between these two frameworks.
متن کاملA caudal proliferating growth center contributes to both poles of the forming heart tube.
Recent studies have shown that the primary heart tube continues to grow by addition of cells from the coelomic wall. This growth occurs concomitantly with embryonic folding and formation of the coelomic cavity, making early heart formation morphologically complex. A scarcity of data on localized growth parameters further hampers the understanding of cardiac growth. Therefore, we investigated lo...
متن کاملFocusing on spindle poles.
Spindle poles are discernible by light microscopy as the sites where microtubules converge at the ends of both mitotic and meiotic spindles. In most cell types centrosomes are present at spindle poles due to their dominant role in microtubule nucleation. However, in some specialized cell types microtubules converge into spindle poles in the absence of centrosomes. Thus, spindle poles in centros...
متن کاملPoles of regular quaternionic functions
This paper studies the singularities of Cullen-regular functions of one quaternionic variable, as defined in [7]. The quaternionic Laurent series prove to be Cullen-regular. The singularities of Cullenregular functions are thus classified as removable, essential or poles. The quaternionic analogues of meromorphic complex functions, called semiregular functions, turn out to be quotients of Culle...
