In this work the Arrhenius parameters and heat of reaction for the esterification of acetic anhydride by methanol and the esterification of propionic anhydride by 2-butanol were determined using a CPA 202 reaction calorimeter (ChemiSens). Three reaction rate models were tested for each of the esterification reactions, two of which assumed autocatalytic behaviour. The autocatalytic models were base

By collecting distances from the literature, a set of 73 planetarynebulae with mean distances of high accuracy is derived. This sample isused for recalibration of the mass-radius relationship, used by manystatistical distance methods. An attempt to correct for a statisticalpeculiarity, where errors in the distances influences the mass-radiusrelationship by increasing its slope, has been made for t

This paper addresses an important but so far neglected episode in the post-1949 history of China – the impact of the so-called 'Cultural Revolution' on the country's ethnic minority populations. Specifically, it attempts to deal with the movement as it unfolded in the province of Yunnan where, at one stage, it became an attempt by a political leadership in the provincial capital, dominated by mili

We give a proof of the Nirenberg-Treves conjecture: that local solvability of principal-type pseudo-differential operators is equivalent to condition (Psi). This condition rules out sign changes from - to + of the imaginary part of the principal symbol along the oriented bicharacteristics of the real part. We obtain local solvability by proving a localizable a priori estimate for the adjoint opera

The essence of the bromodeoxyuridine (BrdUrd)-flow cytometry (FCM) technique is that cells are labelled with the thymidine analogue BrdUrd. They are then allowed to progress through the cell cycle in a BrdUrd-free environment during the postlabelling time period. At a postlabelling time shorter than the length of the S phase (Ts), cells are fixed and prepared for FCM-mediated analysis of BrdUrd an

The article is based on the string-hypothesis, which has important scientific consequences. Science has meant to associate the notion of number with the strict operation of counting. However, recent account of string-theoretical approaches is sharply distinguishing ”number” from ”magnitude”. In studying ”spinning” strings in the context of language, it is shown that rotation is a valid concept. Fo

I samband med byggandet av den nya järnvägssträckningen mellan Landskrona och Helsingborg byggdes kring år 2000 flera nya pågatågsstationer både längs den nya järnvägssträckningen men även längs med den tidigare järnvägen. Dessa nya stationer som placerades på orter som tidigare helt saknat tågtrafik ger en möjlighet att jämföra utvecklingen på dessa orter med utvecklingen på andra liknande orter.

1. A new methodological approach for detailed study of the organization of the cerebellar corticonuclear projection was evaluated in barbiturate-anaesthetized cats. Extracellular field potentials were simultaneously recorded in nucleus interpositus anterior and in the forelimb area of the C3 zone, at the cerebellar surface. On electrical and natural stimulation of the forelimb skin, the evoked pos

BACKGROUND: Insulin resistance was found in some but not in all previous studies of non-diabetic first degree relatives of Type 2 diabetic patients. Small study groups, ethnic differences and/or non-optimal techniques may explain the conflicting results. AIM: To study the impact of a family history of Type 2 diabetes on insulin action in a large group of non-diabetic Europeans using the 'gold stan

Intractable conflicts are by definition difficult to resolve. This study ventures into the identity dynamics of those conflicts and argues that those identity aspects must be addressed in order to locate constituencies for change. Through the employment o theories of conflict transformation, identity and narrative, the dissertation forwards thoughts regarding the importance of inside actors formul

Induced neurons (iNs) offer a novel source of human neurons that can be explored for applications of disease modelling, diagnostics, drug screening and cell replacement therapy. Here we present a protocol for highly efficient generation of functional iNs from fetal human fibroblasts, and also demonstrate the ability of these converted human iNs (hiNs) to survive transplantation and maintain their
