A seismic approach is used to estimate the thickness and elastic stiffness constants of asphalt or concrete slabs. The overall concept of the approach utilizes the robustness of the multichannel seismic method. A multichannel-equivalent data set is compiled from multiple time series recorded from multiple hammer impacts at progressively different offsets from a fixed receiver. This multichannel si
Microsomal membrane preparations from the immature cotyledons of safflower (Carthamus tinctorius) catalysed the interconversion of the neutral lipids, mono-, di-, and triacylglycerol. Membranes were incubated with neutral lipid substrates, 14C-labelled either in the acyl or glycerol moiety, and the incorporation of radioactivity into other complex lipids determined. It was clear that diacylglycero
We use semiconductor (Si) and metallic (Al, Zr) transmission filters to shape, in amplitude and phase, high-order harmonics generated from the interaction of an intense titanium sapphire laser field with a pulsed neon gas target. Depending on the properties of the filter, the emitted attosecond pulses can be optimized in bandwidth and/or pulse length. We demonstrate the generation of attosecond pu
Pineal evolution is envisaged as a gradual transformation of pinealocytes (a gradual regression of pinealocyte sensory capacity within a particular cell line), the so-called sensory cell line of the pineal organ. In most non-mammals the pineal organ is a directly photosensory organ, while the pineal organ of mammals (epiphysis cerebri) is a non-sensory neuroendocrine organ under photoperiod contro
A kinetic study of the reduction of nitric oxide by ammonia in the presence of oxygen on a novel catalyst prepared as a physical mixture of V2O5-WO3/TiO2 catalyst and a natural silicate (sepiolite) was carried out. The steady-state differential reactor data were fitted to several equations using a discriminating method based on physical and statistic criteria. The best fit was obtained from a mode
This article is an interdisciplinary study of CCP military decision making at the outset of the Civil War. The historical phenomenon of the Communists’ invocation of “Madrid” is studied in the context of the Chinese civil war in Manchuria, particularly the battle of Sipingjie. The strategic culture of the Communist leaders is discussed thematically in terms of their desire for a decisive battle, t

This thesis links biogeochemical cycling to classical ecology. Predictions derived from food chain theory, based on Lotka-Volterra type of interactions, were tested in aquatic environments with the main hypothesis that consumers affect lower levels of organization by both predation and excretion of limiting nutrients. From tank experiments it was concluded that predation may affect prey populatio
This study is about the agrarian reforms and policies of the military regime in Ethiopia in the period of its rule between 1974 and 1991. It is a descriptive and qualitative study of a set of agrarian policies which seeks to establish both the unrealized potential of the early and baisc reforms such as the 1975 Land Reform and Peasant Associations and the limitations of subsquent policies of colle
Analys av Michael Hanekes Pianisten (La Pianiste, 2001).
The natural isotope oxygen-18 and artificially injected tritium are used for studying the percolation of soil water. Particle velocity, progression rate and soil moisture flux are distinguished from each other. Water particle velocities and seasonal groundwater recharge are determined in glacio-fluvial deposits and in till soils. In the glacio-fluvial deposits of the Uppsala Esker it is found that
This paper is an informal collection of observations on how established rewriting techniques can be applied to or need to be adapted for use in non-associative algebras, operads, and PROPs.
Antigenicity, the ability to bind to members of repertoire of diverse immune receptors, is a concept that is poorly characterised with respect to its defining parameters. To learn more about its makeup, we have investigated the ability of two peptides with highly related sequences, derived from the tumour-associated antigen mucin-1, to recruit in vitro members from a large naive repertoire of synt
