Method for producing cyclic carbonates

Linear or cyclic carbonates as potential monomers for isocyanate-free polyurethanes and polycarbonates were prepared from polyols and dialkylcarbonatesor diphenyl carbonates. This invention was developed to produce linear or cyclic carbonates with or without using catalysts. Polyol compounds were reacted with carbonates such as dimethylcarbonate and diethylcarbonate to produce thecorresponding lin

Analysis of complexes formed by small gold nanoparticles in low concentration in cell culture media

New nanomaterials are constantly developed with applications in everything from cosmetics to high tech electronics. Assessing their biological impact has been done by analysis of their adsorbed protein corona, in vitro cell assays, and larger scale ecotoxicological studies. This has proved to be a huge challenge due to the wide range of available nanomaterials and their unpredictable behaviour in

Aquatic environment monitoring using a drone-based fluorosensor

A drone-based system for monitoring of laser-induced fluorescence from the aquatic environment was constructed. Fixed-range remote-sensing demonstration measurements were performed, and field recordings of natural river water fluorescence, oil-slicks as well as dye-marked natural water volumes were taken at drone flying heights of about 10 m. Our fluorosensor, weighing only 1.5 kg, and carried by

Feature analysis and prediction of ice regime in the source region of the Yellow River

The Yellow River is a river where serious ice disasters frequently take place in winter. In recent years, the stable frozen period has decreased and the frequency of intermittent freeze periods has increased. After analysing the main factors influencing the ice regime, the prediction factors can be selected. Using multiple linear regression (MLR) and artificial neural network (ANN) methods, this p

Second Primary Cancers in Patients with Invasive and In Situ Squamous Cell Skin Carcinoma, Kaposi Sarcoma, and Merkel Cell Carcinoma : Role for Immune Mechanisms?

Second primary cancers (SPCs) are becoming a common cancer entity, which may interfere with survival in relatively benign first primary cancers. We examined the hypothesis that immune dysfunction may contribute to SPCs by assessing SPCs associated with known immune responsive skin cancers, invasive and in situ squamous cell carcinoma, Kaposi sarcoma, and Merkel cell carcinoma. Cancers were identif

Online validation of combined mood induction procedures

Film clips, music, and self-referential statements (termed Velten, after their originator) have been successfully used to temporarily induce sadness and happiness. However, there is little research on the effectiveness of these procedures combined, particularly in internet-based settings, and whether Velten statements contribute to alter mood beyond the effect of simple instructions to close one’s

Aortic effects of thyroid hormone in male mice

It is well established that thyroid hormones are required for cardiovascular functions; however, the molecular mechanisms remain incompletely understood, especially the individual contributions of genomic and non-genomic signalling pathways. In this study, we dissected how thyroid hormones modulate aortic contractility. To test the immediate effects of thyroid hormones on vasocontractility, we use

Securitizing the “Other” in the European Far-Right Imaginary

Europe is in the midst of a generational transformation that is as much rooted in a complex constellation of socio-economic crises, as it is the product of an ideological revolution, championed by the far-right, in which the Western Balkans, in particular, have become a veritable totem for real and imagined problems confronting the EU and “the West” more broadly.

Artificial intelligence-based versus manual assessment of prostate cancer in the prostate gland : a method comparison study

Aim: To test the feasibility of a fully automated artificial intelligence-based method providing PET measures of prostate cancer (PCa). Methods: A convolutional neural network (CNN) was trained for automated measurements in 18F-choline (FCH) PET/CT scans obtained prior to radical prostatectomy (RP) in 45 patients with newly diagnosed PCa. Automated values were obtained for prostate volume, maximal

Scoliosis in cerebral palsy

Cerebral pares (CP) är den vanligaste orsaken till motorisk funktionsnedsättning hos barn och ungdomar och årligen föds ca 200 barn med CP i Sverige. Symtomen vid CP varierar, men karaktäriseras av bland annat nedsatt rörelseförmåga och nedsatt förmåga att stabilisera kroppen. Nästan åtta av tio vuxna med CP besväras av korta och spända muskler, snedställda leder och smärta som påverkar deras funkBackgroundIndividuals with cerebral palsy (CP) have an increased risk for scoliosis, especially those with low gross motor function, affecting both quality of life and overall function. The aims were to increase the knowledge on the development of, and predictors for scoliosis and the use of spinal orthoses in individuals with CP, and also to evaluate the Caregiver Priorities and Child Health Inde

Den skandinaviska myntunionen – vad säger den om EMU?

Mellan 1873 och 1924 ingick Sverige i en valutaunion tillsammans med Danmark och Norge – den skandinaviska myntunionen (SMU) byggd på den gemen- samma valutaenheten – kronan. Denna artikel belyser tillkomsten, effekterna och upplösningen av den skandinaviska myntunionen samt jämför den med EMU. Ett medlemskap i EMU kräver mer av ekonomisk och politisk anpassning än vad ett medlemskap i SMU gjorde

Federative Organizations: : The Effects of Double Binding Contracts

A distinguishing feature of the federative organization is the ownership relationship. The owners are simultaneously both the providers of risk capital and the main suppliers (or customers) in relation to the unit owned. In other words there is a double binding contractual relation between owners and owned. In this paper the effects of the double binding contract are discussed, as well as the part

Geographical proximity and the transmission of drug abuse among siblings : Evaluating a contagion model in a Swedish National Sample

AimsCan drug abuse (DA) be transmitted psychologically between adult siblings consistent with a social contagion model?MethodsWe followed Swedish sibling pairs born in 1932-1990 until one of them, sibling1 (S1), had a first DA registration. We then examined, using Cox regression, the hazard rate for a first registration for DA in sibling2 (S2) within 3 years of a first DA registration in S1 as a f
