The purpose of this study is to examine the optimal hedge ratio for the currency exposure of foreign investments. The optimal hedge ratio is determined after evaluating our portfolios from the three perspectives; ex-ante, ex-post and profit/loss. The ex-ante perspective is examined by the usage of historical simulation to calculate VaR on 11 portfolio pairs. Each pair consists of a portfolio with
Acoustophoresis, i.e., the contactless manipulation of small cells or particles via acoustic waves is a gentle and label-free method that can, amongst others, be used to isolate rare cells such as circulating tumor cells from blood. To isolate enough cells, a large amount of sample needs to be processed in a reasonable amount of time. In a clinical setting, usually around 10 mL of blood can be col
In January of 2021, the former President of the United States was banned from nearly every social media platform as a result of his actions during the January 6th attack on the U.S. Capitol. After a year of development, Trump’s company, Trump Media and Technology Group, released Truth Social, a Trump-centric social media platform, in February 2022. Although Trump’s bans from social media have most
The paper analyses the legal framework for the collection and distribution of remote sensing data, particularly in the field of sustainable development and environmental protection at the European level. The research firstly focuses on the historical evolution of space law at the international, European, and national levels, starting from the 1970s. In parallel, environmental law has rapidly devel
A supercritical fluid extraction methodology was used to extract flavoring and bioactive compounds from truffles. Some parameters such as CO2 flow rate (1–3 mg/mL), extraction time (15–90 min) and different trapping food matrices (grape seed oil, gelatin, agar agar and water) were optimized using response surface methodology to enhance extraction and trapping yields. The optimal conditions (2.27 m
Objectives Peak exercise systolic blood pressure (SBP) is associated with future cardiovascular disease (CVD) and mortality. We aimed to evaluate the predictive value of different SBP patterns at the end of exercise with these outcomes. Methods We studied 6329 adults (45% women) referred for exercise testing, with test duration of 6-14 min, maximal effort and valid SBP measurements at the end of e
Loss of soil organic carbon (SOC) from farmland is a key threat to the capacity of soils to provide ecosystem services and exacerbates climate change. In alignment with a published protocol, we conducted a review and meta-analysis of time series of SOC measurements in long-term agricultural experiments to study absolute SOC changes under different agricultural management regimes. Our results show
The present study aims at evaluating the role of protein kinase C (PKC) in the development of acute lung injury, production of inflammatory mediators and expression of adhesion molecules on leukocytes after induction of acute pancreatitis (AP). AP was induced by the intraductal infusion of 5% sodium taurodeoxycholate in the rat. The animals had the PKC inhibitor polymyxin B administered intraperit
Objectives: To identify characteristics of older adult emergency department (ED) patients aged ≥65 with suicidal ideation and/or behavior. Methods: A single center retrospective chart review analyzed 392 patients (≥65) with suicidal ideation and/or behavior (2013–2019). Comprehensive full-text searches were used. Subgroup analyses for age and gender were conducted. Results: Depressive disorder was
Implementation av ozonering som teknik på avloppsreningsverk är en av de lösningar som har visat sig effektiv för att avlägsna läkemedelsrester och andra mikroföroreningar och förhindra att de hamnar i naturliga vattendrag. Uppkomsten av transformationsprodukter till följd av ozonering och hur väl ett efterföljande biologiskt reningssteg kan ta hand omdem ett område där mer kunskap behövs. I dettaThe implementation of ozonation technology in sewage treatment plants is a solution that has proven efficient in removing residual pharmaceutical substances and other micropollutants to prevent their spreading in natural water bodies. The appearance of transformation products originating from micropollutants as a result of ozonation, and how well biological post treatment can remove these is a res
In photonuclear experiments precise location of the photon beam relative to the experimental sample is critical. Previously used techniques such as using photographic film to identify the position, intensity and centroid of the beam is time-consuming and a faster method is required. PILATUS is a single-photon-counting pixel detector developed at the Paul Scherrer Institute (PSI), Switzerland. It i
CEREBRAL ISCHEMIA ASSOCIATED with subarachnoid hemorrhage may have severe consequences for neuronal functioning. The excitatory amino acid neurotransmitters glutamate and aspartate have been shown to he of particular importance for ischemia and ischemic neuronal damage. For seven patients who underwent early surgery for ruptured intracranial aneurysms, intracerebral microdialysis of glutamate and
In this study, a two-dimensional numerical model for water flow and solute transport, Hydrus-2D, was used to investigate the impact of landfill cover thickness and the antecedent water content (Ө) of the soil beneath the landfill on the chloride percolation below the landfill. Series of simulation scenarios were performed using season varying climatic data during a 30-year period including two var
Two reactors, initially operated at 14 and 23 +/- 1 degrees C (RA and RB, respectively), were inoculated with a bacterial consortium enriched and acclimatized to the respective temperatures over 4 months. The biofilms, formed in the reactors, were studied using scanning electron microscopy, cultivation of the biofilm microflora, and physiological analysis of the isolates. Two bacteria able to mine
Intravenous infusions of 750 and 1000 ml 2.2% sodium citrate were given over a 60 min period to 17 pigs to study its effect on aortic pressure, electrocardiogram, ionised calcium, and citrate clearance. In group 1 (seven pigs) the animals did not receive calcium and the median survival time was 30 min (range 20-70 min). In groups 2 and 3 (five in each group) the pigs were treated with calcium chlo
Lipoprotein lipase activity in intact epididymal adipose tissue of fasted rats increased rapidly after treatment with insulin in vivo. In contrast, lipoprotein lipase activity in adipocytes isolated from the contralateral fat pads remained essentially unchanged. When adipocytes were incubated for 30 min at ambient temperature in vitro, about 2 times more lipoprotein lipase activity was found in th
Objective: To explore the role of MTNR1B rs10830963 and G6PC2 rs560887 variants in the pathogenesis of impaired fasting glucose (IFG) in obese adolescents. Methods: A total of 346 Caucasians, 218 African-Americans, and 217 Hispanics obese children and adolescents underwent an oral glucose tolerance test (OGTT) and 518 underwent the evaluation of insulin secretion by the oral minimal model (OMM). A
Risk-taking can be either adaptive or maladaptive depending on the context, but maladaptive risk-taking sometimes has serious consequences. Understanding how self-control and other aspects of personality are related to risk-taking is important, as self-control can be improved through training. We examined how the regulative temperamental trait Activation control interacts with the reactive traits
Incorporation of nanoscale catalysts into porous structures of SOFC has been proven highly successful in increasing active sites and catalyst utilization. In addition, electrochemical reactions as well as heat transfer process in porous anode are strongly affected by complex porous structures. It is believed that study of anode thermal properties are critical for SOFC design and operation. In this
