Cis- and trans molybdenum oxo complexes of a prochiral tetradentate aminophenolate ligand : Synthesis, characterization and oxotransfer activity

Reaction of [MoO2Cl2(dmso)2] with the tetradentate O2N2 donor ligand papy [H2papy = N-(2-hydroxybenzyl)-N-(2-picolyl)glycine] leads to formation of the dioxomolybdenum(VI) complex [MoO2(papy)] (1) as a mixture of cis and trans isomers. Recrystallization from methanol furnishes solid cis-1, whereas the use of a dichloromethane-hexane mixture allows for the isolation of the trans-1 isomer. Both isom

Explaining decoupling in high income countries : A structural decomposition analysis of the change in energy footprint from 1970 to 2009

The decoupling of energy use from economic growth is an essential element in the transition to a sustainable future. However, little is known about the long-term drivers of decoupling, especially considering the possibility that it is at least partially due to increased trade. This study uses structural decomposition analysis to examine the main factors that contribute to changes in the energy foo

Visions of a Martian future

As we look beyond our terrestrial boundary to a multi-planetary future for humankind, it becomes paramount to anticipate the challenges of various human factors on the most likely scenario for this future: permanent human settlement of Mars. Even if technical hurdles are circumvented to provide adequate resources for basic physiological and psychological needs, Homo sapiens will not survive on an

Quantitative landscape reconstruction and erosion history during the past 1,100 years in the Skogaryd Research Catchment, southern Sweden

A sediment sequence from a small forest lake in southwestern Sweden was investigated to explore the effects of forestry and land-use on catchment erosion and delivery of organic and minerogenic matter to the lake. Catchment-scale vegetation changes during the last 1,100 years were reconstructed quantitatively at 50-year resolution using pollen analysis and the Landscape reconstruction algorithm (L

Multiple Nonfamilial Unilateral Trichoepitheliomas : Report of a Case-Mini Review of the Literature

Trichoepitheliomas are benign skin tumors with follicular differentiation that present most commonly as solitary lesions. They can also present as multiple centrofacial papules due to several mutations in the CYLD gene. Multiple unilateral trichoepitheliomas in a linear or dermatomal distribution may rarely be seen. Herein, we report a case of multiple unilateral trichoepitheliomas on the face of

Cold war television diplomacy : The German Democratic Republic on Finnish television

Following the formal diplomatic recognition of the German Democratic Republic (GDR) by the Nordic countries in 1972, an intensive collaboration over the Baltic Sea was initiated in a number of societal fields (Almgren, 2009; Hentilä, 2006; Linderoth, 2002; Åkerlund, 2011), one of which was broadcasting, particularly public service television. As an accommodating yet non-aligned neighbour of the So

Elevated plasma tyrosine kinases VEGF-D and HER4 in heart failure patients decrease after heart transplantation in association with improved haemodynamics

Receptor tyrosine kinases (RTKs) are implicated in cardiovascular growth and remodelling. We aimed to identify the plasma levels of RTKs and related proteins and their association with haemodynamic alterations in heart failure (HF) and related pulmonary hypertension (PH) following heart transplantation (HT). Using proximity extension assay, 28 RTKs and related proteins were analysed in plasma from

Master protocols in clinical trials : a universal Swiss Army knife?

Master protocols combine several sub-trials, each with their own research objectives, which is usually presented as one single clinical trial application. Master protocols have become increasingly popular in oncology and haematology, as either basket, umbrella, or platform trials. Although master protocols are intended to accelerate drug development and to reduce futility, their use poses challeng

Interfacial properties and interaction between beer wort protein fractions and isohumulone

It is well known that both protein and iso-humulone, originating from barley malt and hops respectively, play important roles in beer foam stability. In this study, we hypothesize that the interaction of iso-humulone and different beer proteins will give rise to adsorbed layers with different characteristics at hydrophobic surfaces. The properties of these adsorbed layers are likely to play a cruc

A simple wavelet-based test for serial correlation in panel data models

Hong and Kao (2004) proposed a class of general applicable wavelet-based tests for serial correlation of unknown form in the residuals from a panel regression model. The tests can be applied to both static and dynamic panel models. Their test, however, is computationally difficult to implement, and simulation studies show that the test has poor small-sample properties. In this paper, we extend GenHong and Kao (2004) proposed a class of general applicable wavelet-based tests for serial correlation of unknown form in the residuals from a panel regression model.

Limiting conditions for a sustained flame over condensed fuels : Analysis by experiments and stagnant layer theory

Ignition and extinction characteristics of a material determine whether a fire will be initiated and grow. In fire safety engineering, where modellers deal with a multitude of materials, simplified thresholds are commonly used to determine when ignition and extinction occur.Such a threshold is the critical mass flux, which describes when sufficient fuel vapour is produced to support sustained flam
