Three methods are presented to calculate the load distribution in a chain drive containing two sprockets and one chain. The rollers, which are in contact with the sprockets, can move along the tooth flanks and their positions are given by force equilibrium. Since the positions of the rollers, and thereby also the load distribution, depend on the two connecting spans, it has been necessary to inclu
A systematic study of cell membrane morphologies whose structure is governed by cubic symmetries has been performed. It is suggested that they are described by periodic cubic surfaces for which space filling surface foliations given by truncated Fourier series defined by the space groups is used as structural representations. Using this a method is developed which enables a direct ultrastructural
This paper examines how social relations and norms contribute to the emergence of generalized trust in economic action. Our core proposition is that the more positive the local social exchange relationship, the greater an actor’s propensity to place trust in strangers. Our research design integrates behavioral measures elicited by incentivized experimental trust games with survey data using a rand
The Gas in scattering media absorption spectroscopy (GASMAS) technique provides new opportunities to nondestructively study gas in highly scattering natural and man-made porous materials. In this paper, we report applications of the GASMAS method on wood samples using diode-laser-based spectroscopy on molecular oxygen. And the integrated oxygen absorption for wood of different densities and the an

Ökar världens befolkning snabbare än tillgången på mat? Är lösningen på världens livsmedelsproblem att omfördela maten mellan fattiga och rika länder? Göran Djurfeldt svarar nej på båda frågorna. Mera mat handlar om produktionen snarare än om fördelningen av livsmedel: världens jordbruk måste bli effektivare för att kunna mätta en växande befolkning. Boken analyserar jordbruket i ett globalt pers
Atherosclerosis as a disease is postulated to stem from a response to injury of the arterial wall by various stimuli. The inflammatory response is proposed to mediate intimal formation after injury. One pathway of cellular response to injury is through transcription factor NF-kB. We show that balloon injury of rat arteries leads to increased NF-kB activity and ICAM-1 expression, associated with i
The (dynamic) frame model, originating in artificial intelligence and cognitive psychology, has recently been applied to change-phenomena traditionally studied within history and philosophy of science. Its application purpose is to account for episodes of conceptual dynamics in the empirical sciences (allegedly) suggestive of incommensurability as evidenced by “ruptures” in the symbolic forms of h
