Three standard approaches of finding Value at Risk; age weighted historical simulation, volatility weighted historical simulation and t – distribution were compared with Value –at – Risk calculated using generalized extreme value theory during the period 2000 to 2010 to see which approach that would give the most accurate forecast of actual losses during the two volatile times within the time fram

UNICEF reports and daily newspaper reports suggest that street children are excluded from existing child rights facilities in Bangladesh. To examine the situation of social exclusion of street children, this paper examined the development policies for children in Bangladesh to understand how the existing policies can protect street children‟s rights and how they could enjoy country‟s currently ava

The purpose of this report is to develop a model that identifies and reveals the total carbon dioxide emissions generated throughout in- and outbound freight transport made by Höganäs Sweden. The developed model is to be used for future environmental calculations and also act as a tool for discovering new areas of environmental improvements. During the developing process of the model a key issue

The growing interest in using population balance modeling to describe emulsification processes has spurred an interest in experimentally measuring the breakup frequency. This contribution classifies, compares, and critically reviews the different methods that have been suggested for measuring the breakup frequency, applicable to emulsification devices. Two major approaches can be seen in previous

Large drop towers let you experience a couple of seconds of nearly free fall before stopping gracefully in magnetic brakes or bouncing a number of times on compressed air, as in the Turbo Drop tower considered in this work, where many complementary representations are used. An accelerometer taken along on the ride captured the forces experienced by the body, and a pressure sensor provided a simult

Pandemics such as Covid-19 have posed a set of questions concerning safe space usage given the risk of virus transmission in confined and open spaces. In this context, this report presents a risk analysis methodology for the use of crowd modelling tools as an aid to assess safety in confined and open spaces. Crowd models can be used to investigate people movement in the built environment, thus the

Purpose: To assess the performance of a 4-step algorithm for neurological prognostication after cardiac arrest recommended by the European Resuscitation Council (ERC) and the European Society of Intensive Care Medicine (ESICM). Methods: Retrospective descriptive analysis with data from the Target Temperature Management (TTM) Trial. Associations between predicted and actual neurological outcome wer

The objective of this critical review was to provide a comprehensive summary of paralytic shellfish toxins(PSTs) producing species and knowledge gaps in detecting PSTs in drinking water resources, with a focuson recent development of PSTs monitoring methods and tools for drinking water monitoring. PSTs, whichare also called Saxitoxins (STXs), are a group of neurotoxins not only produced by marine

The sexes may have different optima in cognitive traits due to differences in life history strategies and the expense of investing in metabolically costly brain tissue. However, given genetic correlations, each sex could be constrained from reaching its cognitive optimum due to intralocus sexual conflict. We compared learning performance of two male alternative reproductive tactics and females fro

Vegetation responds to drought through a complex interplay of plant hydraulic mechanisms, posing challenges for model development and parameterization. We present a mathematical model that describes the dynamics of leaf water-potential over time while considering different strategies by which plant species regulate their water-potentials. The model has two parameters: the parameter λ describing th

Radionuclide molecular imaging of cancer-specific targets is a promising method to identify patients for targeted antibody therapy. Radiolabeled full-length antibodies however suffer from slow clearance, resulting in high background radiation. To overcome this problem, a pretargeting system based on complementary peptide nucleic acid (PNA) probes has been investigated. The pretargeting relies on s

Lactone flavors with fruity, milky, coconut, and other aromas are widely used in the food and fragrance industries. Lactones are produced by chemical synthesis or by biotransformation of plant-sourced hydroxy fatty acids. We established a novel method to produce flavor lactones from abundant non-hydroxylated fatty acids using yeast cell factories. Oleaginous yeast Yarrowia lipolytica was engineere

In this work, atmospheric pollutant emissions of NOx, SOx, CO, particulate matter (PM), total organic compounds (TOC), and CO2 from larger stationary sources of pollutants in Brazil were inventoried and spatialized over the whole Brazilian territory for the base year 2011. The developed inventory comprises a total of 16 refining units, 1730 thermoelectric power plants (TPPs), 96 cement industries,

Background: Gallbladder cancer (GBC) has a poor prognosis. The aim was to develop and validate a preoperative risk score for incidental gallbladder cancer (IGBC) in patients scheduled for cholecystectomy. Methods: Data registered in the nationwide Swedish Registry for Gallstone Surgery (GallRiks) was analyzed, including the derivation cohort (n = 28915, 2007–2014) and the validation cohort (n = 78

Climate change researchers argue that a residual domain exists beyond the limits of adaptation to prevent deleterious climate change impacts: this has been labeled as “loss and damage.” Over the last 8 years, there has been significant growth in loss and damage scholarship thus making it imperative to take stock of what we know already and directions for future research. We undertook a quantitativ

The concept of critical performativity–efforts to make critical research more relevant for groups outside academia and develop and communicate action-relevant critical insights with some potential effect–has received considerable interest. Much of this has focused on debates about the core concept and principles. This paper argues for the need to “do”–more than talk about–critical performativity a

Background: Since its discovery in 2007, the importance of the human gut bacterium Prevotella copri (P. copri) has been widely recognized with its links to diet and health status and potential as next generation probiotic. Therefore, precise, convenient and cost-effective diagnostic tools for the detection and quantification of P. copri from clinical and environmental samples are needed. Results:

The aim of the present investigation was to test the Lysholm knee scoring scale from 1985 for sensitivity and reliability. Thirty-one patients with one of four different diagnoses: anterior cruciate ligament rupture (ACL), meniscus tear (MT), patello-femoral pain syndrome (PFPS) and lateral ankle sprain (LAS) participated in the study. None of the patients were in the acute phase of injury, and no

Silver particle-free inks display immense superiority and potential over silver nanoparticle-based inks in the aspect of synthesis, flexibility and low-temperature processing, which has attracted considerable research interest as an alternative for fabricating conductive structures in recent years. Although recent research on silver particle-free inks has led to beneficial results, there are still
