There are compelling reasons for teaching a philosophy of science course to undergraduate life science students. The main reason is to help them understand that modern science is not based upon a single, consistent philosophical system; nor is it based upon common sense, or a method, set of rules or formulas that can be used to make unerring predictions. Rather, science is a dynamic process tha...

The modern world is the product of two momentous changes: the Industrial Revolution of 1800, which brought sustained efficiency advances in economies, and the Demographic Transition of 1900, which channeled those efficiency advances mainly into increased income per capita, instead of increases in population. How these revolutions were connected has been a persistent unsolved puzzle in the histo...

While resistance and rebellion have remained core themes in anthropology at least since the 1960s, anthropologists have paid much less attention to the study of political revolutions as real historical events. Yet there are compelling real-world reasons why they should orient their analytical apparatus and A N T H R O P O L O G Y O F P O L I T I C A L R E V O L U T I O N S 705

LDAP directories have recently proliferated with the growth of the Internet, and are being used in a wide variety of network-based applications. In this paper, we propose the use of generalized queries, referred to as query templates, obtained by generalizing individual user queries, as the semantic basis for low overhead, high beneet LDAP directory caches for handling declarative queries. We p...

Wonderful opportunities await particle physics over the next decade, with the coming of the Large Hadron Collider to explore the 1-TeV scale (extending efforts at LEP and the Tevatron to unravel the nature of electroweak symmetry breaking) and many initiatives to develop our understanding of the problem of identity and the dimensionality of spacetime. PACS: 12.15.-y 13.85.-t 12.60.-i 14.80.Bn F...

RNA structure formation is hierarchical and, therefore, secondary structure, the sum of canonical base-pairs, can generally be predicted without knowledge of the three-dimensional structure. Secondary structure prediction algorithms evolved from predicting a single, lowest free energy structure to their current state where statistics can be determined from the thermodynamic ensemble. This artic...

We address the disparity between the intellectual preparation that is expected in traditional engineering as compared to that accepted in software engineering. Any beginning student of a traditional engineering discipline realizes that their first courses will be steeped in mathematics–calculus and physics in particular. These foundational tools underlie the practical aspects of their future ca...

Zonal separation of particles in density gradients contained in hollow or tubeless rotors has been explored with the aim of developing a preparative counterpart of the analytical ultracentrifuge. A rotor with a capacity of 1625 milliliters has been tested up to 22,500 revolutions per minute, with sucrose density gradients used. Excellent separation of subcellular particles has been achieved as ...

the paper presents the methodology for obtaining the level of noise in three-phase induction motors with squirrel cage rotor. Investigations include a single-speed motor with 3000 r/min and a two-speed motor with 750 and 1500 r/min. The investigated motors (manufactured by a Romanian company) were placed in a semi-anechoic chamber in order to determine the noise-to-frequency characteristics (sp...
