Regioselectivity in C-H activation: reagent control in cyclometallation of 2-(1-naphthyl)-pyridine.

2-(1-Naphthyl)-pyridine () possesses sp(2) C-H bonds in both the γ- and δ-positions and is therefore a suitable substrate for studying the cyclometallation selectivity with different reagents and conditions. Such selectivity studies are reported. Based on deuterium-exchange experiments it is concluded that cycloruthenation with RuCl2(p-cymene) dimer is reversible with kinetic and thermodynamic pre

Optical anisotropy of InAs/GaSb broken-gap quantum wells

We investigate in detail the optical anisotropy of absorption of linearly polarized light in InAs/GaSb quantum wells grown on GaSb along the [001] direction, which can be used as an active region of different laser structures. The energy level positions, the wave functions, the optical matrix elements, and the absorption coefficients are calculated using the eight-band k center dot p model and the

Influence of stray fields on the switching-field distribution for bit-patterned media based on pre-patterned substrates

Using a direct imaging method, we experimentally investigate the reversal of magnetic islands in a bit-patterned media sample based on a pre-patterned substrate. Due to systematic variation of the island distances in the media, we are able to study the influence of the dipolar interaction on the switching-field distribution of the island ensemble. The experimental findings are explained by an anal

Choices of Crisis

This comment on Larner's (2011) article deals with the political power of certain conceptualisations of neoliberalism and questions the Anglo-American ways of reading the history of neoliberalism. The inclusion of key moments of neoliberalisation and crisis outside the Anglo-American world would provide different readings of the processes of neoliberalisation. The ‘choice’ of crises matters for ou

Label-free protein quantification in freshly ejaculated versus post-mating spermatophores of the noble crayfish Astacus astacus.

Crayfish spermatophores are deposited on the body surface of the female during mating and remain there for a period of time before fertilization ensues. Post-mating changes in protein expression level in the noble crayfish Astacus astacus spermatophore were quantified. In-gel digestion and high resolution mass spectrometry were used for label-free protein quantification. One hundred twelve protein

Living in transition - experiences of health and well-being and the needs of adolescents with cerebral palsy.

Transition to adulthood for adolescents in general is a multifaceted process, and for adolescents with cerebral palsy (CP) it also involves transition from child- to adult-oriented support. CP entails a variety and combination of disabilities, which in association with external factors may make the transition to adult health services difficult. The aim of this study was to gain a deeper understand

Effects of predator specialization, host plant and climate on biological control of aphids by natural enemies: a meta-analysis

Aphids are among the most severe invertebrate pests of crops and cause high economic losses. The control of aphids by natural enemies is an essential ecosystem service with high relevance to management strategies applied in agricultural plant production and horticulture. However, the current knowledge on the effectiveness of specialist and generalist predators in aphid control with respect to host

Glucose tolerance and beta-cell function in islet autoantibody-positive children recruited to a secondary prevention study.

AIMS: Children with type 1 diabetes (T1D) risk and islet autoantibodies are recruited to a secondary prevention study. The aims were to determine metabolic control in relation to human leukocyte antigen (HLA) genetic risk and islet autoantibodies in prepubertal children. METHODS: In 47 healthy children with GADA and at least one additional islet autoantibody, intravenous glucose tolerance test (Iv

Iron phthalocyanine on Cu(111): Coverage-dependent assembly and symmetry breaking, temperature-induced homocoupling, and modification of the adsorbate-surface interaction by annealing.

We have examined the geometric and electronic structures of iron phthalocyanine assemblies on a Cu(111) surface at different sub- to mono-layer coverages and the changes induced by thermal annealing at temperatures between 250 and 320 °C by scanning tunneling microscopy, x-ray photoelectron spectroscopy, and x-ray absorption spectroscopy. The symmetry breaking observed in scanning tunneling micros

No increased sperm DNA fragmentation index in semen containing human papillomavirus or herpesvirus

It remains unknown whether human papillomaviruses (HPVs) or human herpesviruses (HHVs) in semen affect sperm DNA integrity. We investigated whether the presence of these viruses in semen was associated with an elevated sperm DNA fragmentation index. Semen from 76 sperm donors was examined by a PCR-based hybridization array that identifies all HHVs and 35 of the most common HPVs. Sperm DNA integrit

Influence of pH-dependent aquatic toxicity of ionizable pharmaceuticals on risk assessments over environmental pH ranges.

Due to variation in pH, ionizable pharmaceuticals entering aquatic environments experience different degrees of ionization, which may affect toxicity. Using data from toxicity testing at only neutral pH may potentially under- or overestimate actual toxicity at pH ranges found in natural aquatic environments. Here we show relative pH-dependent acute toxicity to Daphnia magna for the pharmaceutical

Ultra Low Energy Design Exploration of Digital Decimation Filters in 65 nm Dual-VT CMOS in the Sub-VT Domain

This paper presents an analysis of energy dissipation of a decimation filter chain of four half band digital (HBD) filters operated in the sub-threshold (sub-VT) region with throughput constraints. To combat speed degradation due to scaling of supply voltage, various HBD filters are implemented as unfolded structures. The designs are synthesized in 65 nm CMOS technology with low-power and three th

Physical planning in place-making through design and image building

This paper discusses how physical planning works with place-making through urban design to support image creation in a municipality that aims to create a new image for its city. Two large-scale urban development projects in Sweden are analysed. The analysis focuses on official plans and documentation, and expert interviews. It distinguishes how place-making by physical planning happens through aes

Is there a potential application of a fermented nutraceutical in acute respiratory illnesses? An in-vivo placebo-controlled, cross-over clinical study in different age groups of healthy subjects.

The role of oxidants in viral diseases is fairly complex because it includes metabolic regulation both of host metabolism and viral replication. However, a role for reactive oxygen species (ROS) and reactive nitrogen species (RNS) as mediators of virus-induced lung damage is supported by studies and antioxidants can thus be expected to act at many different levels. The aim of the present pilot stu

High Survivin Levels Predict Poor Clinical Response to Infliximab Treatment in Patients with Rheumatoid Arthritis

Objective: To evaluate if the measurement of survivin in the blood of patients with rheumatoid arthritis (RA) undergoing infliximab treatment has predictive value for treatment response. Methods: The study included 87 consecutive RA patients (age 24-89 years, disease duration 18-526 months) treated with regular infusions of influximab. Survivin levels were measured by enzyme-linked immunosorbent a

Vélomobility and the politics of transport planning

Cycling as a transport mode has gradually become more attractive in cities during the last 10 years. However, not all cities give due consideration to cycling issues in the planning process. In many transport systems, cycling and issues of vélomobility are still neglected. Recent research considers several aspects of cycling, however, few studies have shown why differences in for example modal spl

The divided city – a space for frictional peacebuilding

Through the concept of friction, this article critically examines how the liberal peace travels across differences, accommodates, as well as is accommodated by the spaces it engages, and how it transforms, enables or constrains local as well as international agency. As the liberal peace interplays with the post-conflict realities three sites of friction are identified and examined in the divided c

Hyperparathyroidism and new onset diabetes after renal transplantation.

Secondary hyperparathyroidism persists after renal transplantation in a substantial number of patients. Primary hyperparathyroidism and secondary hyperparathyroidism are both associated with abnormalities in glucose metabolism, such as insufficient insulin release and glucose intolerance. The association of hyperparathyroidism and diabetes after renal transplantation has, as far as we know, not be
