121 COVER Skeletons of turtle, chicken, and mouse. The turtle body plan is unusual in that the ribs are transformed into a carapace, and the scapula, situated outside the ribs in other animals, is found inside the carapace. A report on page 193 explains the evolutionary origin of this inside-out skeletal morphology.

Aims: To design energy-saving control system of electrical system in office buildings; Methods: discusses the structure and function of electric control system of construction equipment, and points out the energy saving mode of the electrical automation control system of construction equipment.

In this paper, we propose a scheme for double-layered mobile P2P systems that enhances energy efficiency by modifying PSM(Power Saving Mode) defined in 802.11. The proposed scheme lengthens the beacon interval adaptively and adopts a known power saving scheme for more power saving. The experimental results showed that the proposed scheme improved 58.3% in terms of the average energy saving and ...

A according to a widely shared view of science, scientific theories predict and explain facts about "observables": objects and properties which can be perceived by the senses, sometimes augmented by instruments. In the tradition associated with logical positivism, this view receives an influential formulation in terms of a supposed distinction between two kinds of vocabularies and an allied cla...

In the triennium 2006–2008, 261 women in the UK died directly or indirectly related to pregnancy. The overall maternal mortality rate was 11.39 per 100,000 maternities. Direct deaths decreased from 6.24 per 100,000 maternities in 2003–2005 to 4.67 per 100,000 maternities in 2006–2008 (p = 0.02). This decline is predominantly due to the reduction in deaths from thromboembolism and, to a lesser e...

The Internet goose has laid countless golden eggs, along with a growing number of rotten ones. But it's the rotten ones that now tempt commercial, governmental, and consumer interests to threaten the Internet's uniquely creative power. The expediently selected, almost accidentally generative properties of the Internet - its technical openness, ease of access and mastery, and adaptability - have...
