1 The study was performed to clarify if apomorphine at the level of the rat corpus cavernosum can produce erectile responses or interfere with nerve-induced penile erection. 2 Apomorphine ( 10(-9) - 10(-4) M) exhibited a 10-fold higher potency to relax phenylephrine ( Phe)-than endothelin-1 ( ET-1)-induced contractions. Relaxant effects of apomorphine in Phe-activated corpus cavernosum did not cha

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

Eae5 in rats was originally identified in two F-2 intercrosses, (DA x BN) and (E3 X DA), displaying linkage to CNS inflammation and disease severity in experimental autoimmune encephalomyelitis (EAE), respectively. This region overlaps with an arthritis locus, Pia4, which was also identified in the (E3 X DA) cross. Two congenic strains, BN.DA-Eae5 and BN.DA-Eae5.R1, encompassing the previously des

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

The evaporative gas turbine (EvGT) pilot plant has been in operation at Lund University in Sweden since 1997. This project has led to improved knowledge of evaporative techniques and the concept of introducing fuel into gas turbines by evaporation. This results in, amongst others, power augmentation, efficiency increase and lower emissions. This article presents the experimental and theoretical re

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

This article examines whether there exists any causal relationship between foreign trade and declining pollution in developed countries. In other words, do developed countries outsource their problems to less developed countries rather than solve them? The case study is the Swedish economy and the two environmental indicators employed are energy consumption and CO2 emissions. No causal relationshi

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
