Abstract A radar study was performed to compare flight parameters between sparrowhawks and common buzzards during autumn migration at the Falsterbo peninsula, Sweden. Common buzzards had higher flight altitudes and were more selective for wind, yet their air - and cross-country speeds were lower than those of sparrowhawks. Furthermore, common buzzards had higher glide ratio, but lower airspeed w
The fall of the Berlin Wall in 1990 signified a new era in European history. Most of the former socialist countries started a process of transition from centrally planned to the market economy already in 1990. Many studies have been undertaken with the aim of analyzing the effects of privatization and transition in former Soviet countries, but there is significantly less literature about privatiza
The purpose of this study was to analyze selected passages of the short story The South Wind by the Iraqi writer Abd el-Malik Nuri, which was done in order to find out how the description of characters, setting, and events, are related to class. The main research questions dealt with how the use of word choice and imagery are used in connection to the setting and characterization, but also how the
Allmänna pensionsfonderna, oftast omnämnda som AP-fonderna, är de största förvaltarna id et allmänna inkomstpensionsystemet. Fonderna har i uppdrag att investera pensionssystemets buffertkapital och eftersträva en hög långsiktig avkastning för att bidra till en hög pension för framtida generationer. För att uppfylla sitt uppdrag investerar fonderna i tusentals företag runt om i världen. Under de sThe Swedish Public Pension Funds, also known as the AP-funds, are the biggest trustees of Swedish pension payments. Their mission is to invest the buffer capital of the pension system and ensure growth that will provide pension disbursements for generations to come. To fulfil this mission investments are made in thousands of companies all over the world. During the last years the AP-funds have bee
The flow field generated by the flow into a jet engine air-intake, with near ground effects, is considered. The axial inflow in the neighborhood of the ground generates a system of unsteady vortices. Some of these vortices extend from the air-intake towards the ground. Some of these vortices are strong enough to dislocate and even lift small objects from the ground up to the air-intake. The dynami
In this chapter a system for tracking the motion of box jellyfish Tripedalia cystophora in a special test setup is investigated. The goal is to measure the motor response of the animal given certain visual stimuli. The approach is based on tracking the special sensory structures - the rhopalia - of the box jellyfish from high-speed video sequences. The focus has been on a real-time system with sim
Popular Abstract in Swedish Under de senaste årtiondena har vattenfärgen i många svenska sjöar och vattendrag ökat. Detta innebär att vattnet blir brunare, och detta fenomen benämns därför brunifiering. Brunifiering är inget unikt för Sverige, utan förekommer på åtskilliga ställen på norra halvklotet. Brunifieringen påverkar det akvatiska ekosystemet och vattnets potentiella samhällsnytta. Ur en eThe term brownification refers to the trend of increasing water color, i.e. the water becoming browner, which has been observed throughout the northern hemisphere over the last decades. Brownification has both ecological and societal implications. From an ecological point of view the impaired light climate may e.g. reduce aquatic primary production and affect predator-prey interactions within the
This article studies a hitherto unexplored dimension of the Chinese Civil War: the disparity between modern military technology and the conceptual and logistical capacities of the two warring sides. The author argues that the advanced weaponry, received by the Nationalists from their ally, the United States, but often captured on the battlefield by the Chinese Communist Party (CCP) forces, proved

Coronavirus disease (COVID-19) booster doses decrease infection transmission and disease severity. This study aimed to assess the acceptance of COVID-19 vaccine booster doses in low, middle, and high-income countries of the East Mediterranean Region (EMR) and its determinants using the health belief model (HBM). In addition, we aimed to identify the causes of booster dose rejection and the main so
The Earth is experiencing unprecedented climate change. Vegetation phenology has already showed strong response to the global warming, which alters mass and energy fluxes on terrestrial ecosystems. With technology and method developments in remote sensing, computer science and citizen science, many recent phenology-related studies have been focused on macrophenology. In this perspective, we 1) rev
The magnitude, direction and cause of precipitation changes across the Indo-Pacific Warm Pool (IPWP) during the Last Glacial Maximum (LGM) remain elusive. In particular, it is still inconclusive whether tropical or extra-tropical factors controlled such precipitation changes. Determining the spatio-temporal distribution of precipitation in the IPWP during the LGM is a valid strategy to address thi
Future global temperature change will have significant effects on society and ecosystems. Earth system models (ESM) are the primary tools to explore future climate change. However, ESMs have great uncertainty and often run at a coarse spatial resolution (usually about 2°). Accurate high-spatial-resolution temperature dataset are needed to improve our understanding of temperature variations and for
Dissolved Organic Carbon (DOC) in inland waters plays an essential role in the global carbon cycle and has significant public health effects. Machine learning (ML) together with remote sensing has emerged as a powerful and promising combination to quantify water quality parameters from space. However, inland water sample data for DOC is limited. Hence, little is known about the potential to quanti
