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

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
The present state of extreme value theory for queues is surveyed. The exposition focuses on the regenerative properties of queueing systems, which reduces the problem to the study of the tail of the maximum $overline X( au)$ of the queueing process ${X(t)}$ during a regenerative cycle $ au$. For simple queues, methods for obtaining the distribution of $overline X( au)$ both explicitly and asymptot
Moisture transport and sorption in wood may not be accurately described by Fick's law of diffusion. The problem of making a model of non-Fickian behaviour (NFB) for wood is discussed. Some measurements in which NFB in wood is clearly seen are also reviewed. Four criteria, which must be satisfied by a model describing sorption in wood cell walls, are presented: (1) the model should not only describ
Popular Abstract in Swedish Syftet med avhandlingen är att analysera den tekniska och organisatoriska ut¬vecklingen inom svensk banksektor under perioden 1975-2003 samt att se hur för¬ändringar i dessa två variabler påverkat produktivitetsutvecklingen. Utgångspunkten för analysen av den tekniska och organisatoriska förändringen är att det föreligger ett komplementärt förhållande mellan informationThe purpose of this thesis is to investigate the relation between technological and organizational change in the Swedish banking sector from 1975 to 2003. Besides analyzing the changes in these two variables the effects of the interaction on productivity changes in the sector are examined. The use of the concept of complementarity as a basis for analyzing the interaction between technological and
Introduction The aim of this work was to study the effects of restricted diffusion in a biological phantom consisting of green asparagus stems using q-space MRI at a clinical scanner. Method Measurements of the full width at half maximum (FWHM) of the displacement distribution were performed with varied diffusion time (T d). The accuracy of the measurements was investigated with respect to the deg
The accuracy of theoretical calculations on models of the blue copper proteins is investigated using density functional theory (DFT) Becke's three-parameter hybrid method with the Lee–Yang–Parr correlation functional (B3LYP) and medium-sized basis sets. Increasing the basis set to triple-zeta quality with f-type functions on all heavy atoms and enlarging the model [up to Cu(imidazole-CH3)2(SC2H5)
This dissertation studies the historical relation between the Muslim minority and the non-Muslim majority in Yunnan with a combined method: historical criticism supplemented by ethnological interpretation. This relation manifests in history dynamic and dialectical characteristics: concord and conflict. Concord can be found in the stable and balanced periods in the relevant socio-cultural aspects o
