Photovoltaics with Piezoelectric Core-Shell Nanowires

We report on a theoretical discovery of a generic piezoelectric held in strained core shell compound semiconductor nanowires. We show, using both an analytical model and numerical simulations based on fully electroelastically coupled continuum elasticity theory, that lattice-mismatch-induced strain in an epiraxial core shell nanowire gives rise to an internal electric held along the axis of the na

Beroendevård i socialtjänst och sjukvård - En svensk modell att utmana.

Addiction treatment often requires medical, psychosocial and social expertise - and benefits from collaboration. The pronounced role of social authorities in evaluation and treatment is unique to the addiction field. Unified responsibility for evaluation and treatment of addiction is under consideration. Treatment of psychiatric and physical co-morbidity benefits from a unified responsibility with

Cardioprotective treatment strategies

In myocardial ischemia-reperfusion (I/R) injury, complement activation, tissue plasminogen activator (t-PA) and extracellular adenosine triphosphate (ATP) release contribute to myocardial injury. ATP is degraded into adenosine by the enzyme apyrase, and adenosine possesses cardioprotective properties. ADC-1004 is an antagonist of the receptor to the activated complement factor C5a. Hypothermia has

Nanoindentation of thin copper coatings

The structure of interest is a thin, metallic coating of fcc copper, of thickness down to a few nanometers only, resting on a stiffer substrate. The elastic and plastic properties of the thin coating using nanoindentation under different geometrical features such as size of the indenter and coating thickness are determined. The force-displacement curve is monitored during indentation and the preci

Polysulfones with highly localized imidazolium groups for anion exchange membranes

In order to promote phase separation and properties of anion-exchange membranes (AEMs)we have prepared polysulfones with an exceptionally high local concentration of imidazolium groups. Statistical copolymers containing single dioxyphenylene rings directly functionalized with four cationic groups were synthesized by polycondensations of 4,4’-dichlorodiphenylsulfone, 4,4′-isopropylidenediphenol and

Lilla Harrie Mölla

The mill in Lilla Harrie vas belonging to noble families in the medieval period. It was confiscated by the king in 1502 and sold to the archbishop in 1509. By the reformation in the 1530:ies it again came to be owned by the king. It belonged to the castle in Landskrona and in the royal archives it is possible to follow the developement of the mill in detail up to the swedish conquest in 1658. Then

Pulse transmission using leaky lens antenna and RTD-MOSFET wavelet generator

A leaky lens antenna system for short pulse applications is designed, fabricated and characterized. The antenna has very good phase center stability over large bandwidths. The leaky lens antenna is connected to an in-house wavelet generator to transmit 100 ps pulses centered at 57.5 GHz. It is shown that the antenna preserves the reference pulse shape and has very low dispersion.

Problemen förgår, lösningarna består : Organisering av kommunala insatser för unga arbetslösa med försörjningsproblem

In the beginning of the 1990s, Sweden experienced an economic recession. The unemployment rate increased significantly and the proportion of young adults receiving social assistance rose dra-matically. In response, municipalities initiated local intervention programs aimed at reducing the number of young social assistance recipients. In 2005, this population had decreased. However, the organizatio

High preoperative blood levels of HE4 predicts poor prognosis in patients with ovarian cancer

The aim of this study was to assess the clinical value of preoperative blood levels of HE4 as a predictor of overall survival in patients with ovarian cancer and to validate previous data of HE4 and the ROMA algorithm including HE4 and CA125 in discriminating benign and malignant ovarian tumors. Experimental design: The preoperative plasma levels of HE4 and CA125 were analyzed with ELISA in 312 pa

The status of the Nordic populations of the Mallard (Anas platyrhynchos) in a changing world

Dabbling ducks (Anas spp.) are important migratory quarry species, protected as a shared resource under international legislation. However, there is a lack of sufficient high-quality data on vital demographic rates and long-term trends in numbers to judge the conservation status of many duck populations at the flyway level. In response to reported declines in the North-West European flyway populat

Nuclear Genomic Sequences Reveal that Polar Bears Are an Old and Distinct Bear Lineage

Recent studies have shown that the polar bear matriline (mitochondrial DNA) evolved from a brown bear lineage since the late Pleistocene, potentially indicating rapid speciation and adaption to arctic conditions. Here, we present a high-resolution data set from multiple independent loci across the nuclear genomes of a broad sample of polar, brown, and black bears. Bayesian coalescent analyses plac

Competence integration in creative processes

Research on creativity focuses extensively on it as a personal skill or discusses how an organization can contribute to a creative environment for its staff. Rather than referring to the organization as the environment, this paper concerns interorganizational and intraorganizational interaction between different creative individuals who together shape the creative process and output. Specifically,
