reproductive age.3 However, other empirical evidence has indicated that state abortion restrictions have no such impact.4 The relationship between state-level abortion policies and birthrates is even murkier. Since the birthrate is the product of the pregnancy rate and the ratio of births to pregnancies, state abortion policies may affect birthrates by influencing one or both of these factors. ...

HYRAX versus HAAS EXPANSION APPLIANCES

The present study evaluated rapid maxillary expansion (RME) periodontal effects by means of computed tomography (CT), comparing the tooth-tissue-borne and the tooth-borne expanders. The sample comprised 8 girls aged between 11 to 14 years, presenting with Class I or II malocclusions with unilateral or bilateral posterior crossbite. The sample was randomly divided into two treatment groups (Haas...

In this paper, we present a theory of synchronous data-ow languages. Our theory is supported by both some heuristic analysis of applications and some theoretical investigation of the data-ow paradigm. Our model covers both behavioural and operational aspects, and allows both synchronous and asynchronous styles of implementation for synchronous programs. This model served as a basis to establish...

Quantum Einstein-de Haas effect

The classical Einstein-de Haas experiment demonstrates that a change of magnetization in a macroscopic magnetic object results in a mechanical rotation of this magnet. This experiment can therefore be considered as a macroscopic manifestation of the conservation of total angular momentum and energy of electronic spins. Since the conservation of angular momentum is a consequence of a system's ro...
