Climate Variability Impact on the Spatiotemporal Characteristics of Drought and Aridityin Arid and Semi-Arid Regions

Investigating the spatiotemporal distribution of climate data and their impact on the allocation of the regional aridity and meteorological drought, particularly in semi-arid and arid climate, it is critical to evaluate the climate variability effect and propose sufficient adaptation strategies. The coefficient of variation, precipitation concentration index and anomaly index were used to evaluate

Inflammatory bowel disease and biomarkers of gut inflammation and permeability in a community with high exposure to perfluoroalkyl substances through drinking water

Perfluoroalkyl substances (PFAS) can act as surfactants and have been suggested to be capable of affecting gut mucosa integrity, a possible factor in the pathogenesis of inflammatory bowel disease (IBD). So far, only PFOA has been shown to have a positive association with ulcerative colitis. The present study aimed to investigate the association of PFAS and clinically diagnosed IBD in the Ronneby

Search for non-resonant Higgs boson pair production in the bbℓνℓν final state with the ATLAS detector in pp collisions at s=13 TeV

A search for non-resonant Higgs boson pair production, as predicted by the Standard Model, is presented, where one of the Higgs bosons decays via the H→bb channel and the other via one of the H→WW⁎/ZZ⁎/ττ channels. The analysis selection requires events to have at least two b-tagged jets and exactly two leptons (electrons or muons) with opposite electric charge in the final state. Candidate events

Investigating drivers of microbial activity and respiration in a forested bog

Northern peatlands store nearly one-third of terrestrial carbon (C) stocks while covering only 3% of the global landmass; nevertheless, the drivers of C cycling in these often-waterlogged ecosystems are different from those that control C dynamics in upland forested soils. To explore how multiple abiotic and biotic characteristics of bogs interact to shape microbial activity in a northern, foreste

Kan man lita på kamratgranskning?

I en grundkurs i programmering har tidigare delmålskontroller (diagnostiskt prov som kamraträttats) använts. Om delmålskontrollen utförs väl får studenten bonuspoäng som gäller vid första ordinarie tentamenstillfället. I en kurs med många deltagare blir det tidskrävande och kostsamt om läraren skall rätta alla lösningarna för att dela ut bonuspoäng. Syftet med denna undersökning är att se hur bra

Cerebral Oximetry in Syncope and Syndromes of Orthostatic Intolerance

Cerebral autoregulation is crucial for maintaining cerebral blood flow and perfusion. In recent years, the importance of cerebral oxygenation in syncope and orthostatic intolerance (OI) has received increased attention. Cerebral tissue oxygenation can be measured by using near-infrared spectroscopy (NIRS), which determines the ratio of oxygenated hemoglobin to total hemoglobin in cerebral tissue.

Efficacy and safety of inhaled α1-antitrypsin in patients with severe α1-antitrypsin deficiency and frequent exacerbations of COPD

Patients with inherited α1-antitrypsin (AAT) deficiency (ZZ-AATD) and severe chronic obstructive pulmonary disease (COPD) frequently experience exacerbations. We postulated that inhalation of nebulised AAT would be an effective treatment. We randomly assigned 168 patients to receive twice-daily inhalations of 80 mg AAT solution or placebo for 50 weeks. Patients used an electronic diary to capture

Germaine de Staël’s Réflexions sur le procès de la reine : An act of compassion?

In the foreword to the Mercure de France edition of Réflexions sur le procès de la reine, (1996 [1820, 1793]), Chantal Thomas, French historian and writer, writes that this apology in favour of Marie-Antoinette did not help the queen nor the author herself; on the contrary it only made the latter more unpopular. So why did Germaine de Staël write it? Mme de Staël and Marie-Antoinette did not shareIn the foreword to the Mercure de France edition of de Staël. (1996 [1793]. Réflexions sur le procès de la reine.

Scanning probe techniques as an investigation tool for semiconductor nanostructures and devices

Semiconductor nanostructure based devices provide new opportunities for contributing to a sustainable energy usage. This includes harvesting of energy (solar cells) and saving of energy, e.g. in lighting (light-emitting diodes, LEDs) and transfer of energy (power devices). However, development and improvement of nanostructure devices requires thorough characterization and understanding on a singleSemiconductor nanostructure based devices provide new opportunities for contributing to a sustainable energy usage.

Reactions between Grignard reagents and heterocyclic N-oxides : Stereoselective synthesis of substituted pyridines, piperidines, and piperazines

In this perspective we discuss the recent developments of stereoselective synthesis of substituted pyridines, piperidines, and piperazines from cheap and commercially readily available starting materials. Pyridine N-oxides and pyrazine N-oxides are reacted with alkyl, aryl, alkynyl and vinyl Grignard reagents to give a diverse set of heterocycles in high yields. Optically active substituted pipera

Broad modulation of neuropathic pain states by a selective estrogen receptor beta agonist

The effects of estrogens on pain perception remain controversial. In animal models, both beneficial and detrimental effects of non-selective estrogens have been reported. ERb-131 a non-steroidal estrogen receptor beta ligand was evaluated in several pain animal models involving nerve injury or sensitization. Using functional and binding assays, ERb-131 was characterized as a potent and selective e

Claiming Human Rights: The Reflexive Identity of the People

In this chapter I try to discern the shape of a phantom. The phantom is the people in a democracy. The first argument which will be put forward is that democracy cannot exist without such a phantom. But this phantasmagorical presence of the people in society can threaten the very democracy which it makes possible, in two ways. First, the phantom can prove to be no more than that – a mere figment o
