Revisiting the dissolution of cellulose in H3PO4(aq) through cryo-TEM, PTssNMR and DWS

Cellulose can be dissolved in concentrated acidic aqueous solvents forming extremely viscous solutions, and, in some cases, liquid crystalline phases. In this work, the concentrated phosphoric acid aqueous solvent is revisited implementing a set of advanced techniques, such as cryo-transmission electronic microscopy (cryo-TEM), polarization transfer solid-state nuclear magnetic resonance (PTssNMR)

Luminescent PhotoCORMs : Enabling/Disabling CO Delivery upon Blue Light Irradiation

The new luminescent carbonyl compounds [Mn(Oxa-H)(CO)3Br] (1) and [Mn(Oxa-NMe2)(CO)3Br] (2) were synthesized and fully characterized. Complexes 1 and 2 showed CO release under blue light (λ453). Spectroscopic techniques and TD-DFT and SOC-TD-DFT calculations indicated that 1 and 2 release the Oxa-H and Oxa-NMe2 coligands in addition to the carbonyl ligands, increasing the luminescence during photo

Cortical thickness and surface area of left anterior temporal areas affects processing of phonological cues to morphosyntax

Lack of methods to experimentally assess the perceptual processing of sound features and allow one to measure differences in phonological proficiency has been a limitation for speech processing studies in native speakers. Tonal features associated with Swedish word-stems, word accents, which cue grammatical suffixes, constitute, however, such sound features that can be exploited to generate measur

Respiratory burst oxidases and apoplastic peroxidases facilitate ammonium syndrome development in Arabidopsis

Ammonium-nitrogen (NH4+) nutrition is linked to metabolic over-reduction for plants. The characteristic symptom of sole NH4+ nutrition is growth suppression, signifying this condition as the ammonium syndrome. In the present study, we investigated the mechanism of perception of high NH4+ conditions in Arabidopsis thaliana plants by examining apoplastic reactive oxygen species (ROS) metabolism. Maj

Using Confidence Intervals to Determine Adequate Item Sample Sizes for Vocabulary Tests : An Essential but Overlooked Practice

The last three decades have seen an increase of tests aimed at measuring an individual’s vocabulary level or size. The target words used in these tests are typically sampled from word frequency lists, which are in turn based on language corpora. Conventionally, test developers sample items from frequency bands of 1000 words; different tests employ different sampling ratios. Some have as few as 5 o

Background: Since 2015 operations performed in the field of endocrine surgery have been entered into the European registry EUROCRINE®. The aim of this analysis was a description of the current healthcare situation for adrenal surgery in a homogeneous healthcare environment corresponding to the German-speaking countries—or to the presence of the working group on surgical endocrinology (CAEK) of the

Invigning av två ombyggda skolgårdar

Forskningsprojektet Equalizer 2.0 syftade till att förändra skolgårdar utifrån ett inkluderande och normkritiskt perspektiv, detta för att skapa större möjlighet till fysisk aktivitet och rörlighet hos unga människor. Dessa invigdes det angivna datumet på Fäladsgårdens skola och Östratornskolan i Lund.

Genomic and Transcriptomic Analyses of Osteogenic Tumours of Bone

Primary tumours of bone are heterogenous and infrequent neoplasms. Distinguishing between benign, intermediate and malignant entities can in some instances pose a clinical challenge. For some tumour types, there is still much to be learned about the genetic mechanisms that give rise to and drive these tumours forward. With the hope of improving diagnostic accuracy and treatment outcomes on the lon

4E cognition and musical instruments: Modes of Access

In this presentation, I will discuss how the role of instruments in musical practice can be under- stood, through a theoretical framework drawing upon the emerging paradigm of 4E cognition. Ani- mating the discussion are two studies, an interview study and a co-operative inquiry, together forming the empirical basis of my PhD-project. The case here is the simple-system flute, an in- strument that

Opioids for newborn infants receiving mechanical ventilation

Objectives: This is a protocol for a Cochrane Review (intervention). The objectives are as follows:. To determine the benefits and harms of opioid analgesics in neonates (term or preterm) receiving mechanical ventilation, compared to placebo, no drug, other opioids, other analgesics or sedatives.

The impact of occupational and personal factors on musculoskeletal pain - A cohort study of female nurses, sonographers and teachers

Background: Musculoskeletal pain is common in the general population and constitutes a major public health problem. A large proportion of these conditions may be work related. The aim of this study was to explore the relative importance of physical, psychosocial and personal factors, in number of pain sites and in five specific pain sites, among women in common professions with a broad variety of

Epigenetic markers associated with metformin response and intolerance in drug-naïve patients with type 2 diabetes

Metformin is the first-line pharmacotherapy for managing type 2 diabetes (T2D). However, many patients with T2D do not respond to or tolerate metformin well. Currently, there are no phenotypes that successfully predict glycemic response to, or tolerance of, metformin. We explored whether blood-based epigenetic markers could discriminate metformin response and tolerance by analyzing genome-wide DNA

Impact of Octane Number and Injection Timing on Autoignition Behaviour of Gasoline and PRF in PPC

Partially premixed combustion (PPC) is one of the advanced combustion concepts that is being actively investigated. A joint experimental and numerical investigations were conducted to explore the effects of octane number and injection timing on the autoignition behaviour with primary reference fuel (PRF) and gasoline fuels under PPC mode in a light-duty DICI engine. In this study, the start of inj

Influence of Injection Timing on Equivalence Ratio Stratification of Methanol and Isooctane in a Heavy-Duty Compression Ignition Engine

CO2 is a greenhouse gas that is believed to be one of the main contributors to global warming. Recent studies show that a combination of methanol as a renewable fuel and advanced combustion concepts could be a promising future solution to alleviate this problem. However, high unburned hydrocarbon (UHC) and carbon monoxide (CO) emissions can be stated as the main drawback in low load operations whe
