The traditional presentation about historical time-passing consists in a linear succession of facts in which some aspects of the life world evolve from others in an irreversible manner. The presentation of change is connected to the presentation of gradual or revolutionary linear changes that are irrevocable. I believe that this presentation could be considered correct for living organisms, but do

Christopher Polhem (1661-1751), called the father of Swedish mechanics, is the most famous figure in Swedish history of technology and our nation's foremost inventor ever. Remarkably enough, a close survey in a monograph has never been written on this inventor who in many ways initiated the technical and industrial development of Sweden. In this project will Polhem for the first time get a broad a

The concept “Broken Technologies” is related to the question: “Which is the benefit of humanity studies?” Of course the question is rhetorical because, how could this question be answered if the benefit was not obvious? Any answer supposes that we understand what we are asking for and the study of “what we mean” is one of the axes of the epistemology of the humanities. Anyway, we can also put the

Movements of individual articulators are analyzed to elucidate principles of gestural organization in vowels. Procedures for tracking articulator gestures from x-ray motion films, and results obtained on coarticulation in Swedish, Bulgarian, and Greenlandic are reported in Wood [J. Phon. 19, 281–292 (1991); Proc. 3rd Congr. I. C. P. L. A. 191–200, Helsinki (1994); Proc. 13th I. C. Ph. Sc. 1, 392–3

The changing notions of tourism are analyzed by example of Swedish package tours in the 1950s and 1960s, when the dominant means of transportation for package tours changed from buses to airplanes. Simultaneously, Swedish mass tourism developed explosively so that the package tour markets of Scandinavia in the mid-1960s were the largest per capita in Europe. While package tours by bus, dominating

CCD observations of V538 Cas have been made on nine nights during three weeks using the AAVSO Bright Star Monitor. No significant variations were found.

A study on guided waves in a. layered half-space with large velocity contrasts and a decreasing velocity with depth is presented. Multiple mode dispersion curves are calculated in the complex wave number domain, taking into consideration the attenuation caused by leakage into the underlying half-space. The excitability of the modes by a vertical point force on the surface is also calculated. Resul

Movement data are analyzed to elucidate principles of articulator coordination. Procedures for tracking articulator gestures from x-ray motion films, and results obtained from Swedish and Bulgarian work are reported in Wood [J. Phon. 19, 281–292 (1991), Proc. 3rd Congress I.C.P.L.A., 191-200, Helsinki (1994), Proc. 13th I.C.Ph.Sc., Vol. 1, 392–395, Stockholm (1995), J. Phon. (in press)]. Coarticul

Structural flexibility is an essential attribute, without which few proteins could carry out their biological functions. Much information about protein flexibility has come from x-ray crystallography, in the form of atomic mean-square displacements (AMSDs) or B factors. Profiles showing the AMSD variation along the polypeptide chain are usually interpreted in dynamical terms but are ultimately gov

Hereditary cystatin C amyloid angiopathy is a dominantly inherited disorder, characterized by dementia, paralysis, and death from cerebral hemorrhage in early adult life. A variant of the cysteine proteinase inhibitor, cystatin C, is deposited as amyloid in the tissues of the patients and their spinal-fluid level of cystatin C is abnormally low. The disease-associated Leu-68-->Gln mutant (L68Q) cy

To minimize radiation damage, crystal structures of biological macromolecules are usually determined after rapid cooling to cryogenic temperatures, some 150-200 K below the normal physiological range, The biological relevance of such structures relies on the assumption that flash-cooling is sufficiently fast to kinetically trap the macromolecule and associated solvent in a room-temperature equilib
