In 2022, the Yangtze River Basin in China experienced an unprecedented extreme drought, induced by high temperatures and precipitation deficits. Accurate monitoring of such extreme drought events is vitally significant for disaster mitigation under global warming. This study evaluated the effectiveness of two satellite-based precipitation products: the latest Integrated Multi-satellitE Retrievals
Little academic research has been done in the field of energy and conflict with regard to the Russian invasion of Ukraine in 2022. The aim of this thesis is to try to fill this gap by analysing the relationship of energy and conflict in this ongoing war. A further goal is to relate the findings back to the theoretical framework provided by Månsson (2014), in which the different roles that energy c
In this paper, a customized image convolution processor with three level memory hierarchy is implemented on Xilinx VirtexE FPGAs. Due to its fully pipelined datapath for calculations and streamlined data flow architecture, the processor has the performance close to that of TI highest performance C64x processor at less than 1/8 of the clock frequency with substantial I/O bandwidth reductions. Furth
In the generalization of the cranking model from rotation about a principal axis [one dimensional (1D)] to tilted rotation (2D and 3D), the mapping of the lowest total routhian on the yrast band is broken. In tilted rotation the single-particle energy diagrams cannot alone be used to construct the yrast band, because they lack information of the spin component perpendicular to the rotation axis. I
Using Multinational Time Use Study data from France and US, the effect of parental educational level on time spent with children is analyzed. Regressions in which the depent variables are the minutes used in total childcare, household work, leisure, basic childcare, educational childcare and recreational childcare are estimated. The pattern of total childcare is compared to household work and leis
Bakgrund: Utbrändhet har blivit ett populärt ämne som det forskas allt mer på. Internationellt har många studier om läkares utbrändhet gjorts och de har visat att läkare har en hög nivå av utbrändhet. Dessa studier samt andra studier inom stressforskningen har visat på att det finns många olika orsaker som kan leda till stress och utbrändhet. Mycket lite forskning är dock gjord på svenska läkare fTheory: Burnout has become a popular research field with lots of studies being done within the area. Internationally, many studies on physician burnout have been made and they show that physicians have a high level of burnout. These studies as well as other studies within stress research have shown that there are many different factors that can lead to stress and burnout. However, very little rese

Philipp Kaldis är professor i metabolism och leversjukdomar vid Lunds universitet. Han leder en forskargrupp som strävar efter att öka förståelsen för hur metabola sjukdomar utvecklas. Här skriver han själv om sin forskning. "Jag inledde min forskningsbana med att studera celldelning, ett väldigt fascinerande område. Tänk att alla vi människor börjar som en enkel befruktad cell, för att sedan utve

Popular Abstract in Swedish Två av de viktigaste polyaminerna påträffades redan i slutet av 1600-talet, som kristaller i tjursperma och har därför fått namnen spermin och spermidin. Dessa aminer bildas från en annan substans, putrescin, som först isolerades från ruttnande kött. Namnet putrescin kommer från engelskans putrefaction, som betyder förruttnelse. Polyaminer, som kemiskt sett är positivt The polyamines putrescine, spermidine and spermine are essential for cell growth and differentiation. The biosynthesis of polyamines are tightly regulated by feedback mechanisms involving two enzymes, namely ornithine decarboxylase (ODC) and S-adenosylmethionine decarboxylase (AdoMetDC). This thesis deals with the mechanisms behind the polyamine-mediated feedback control of these enzymes. The poly
We report on a large scale calculation concerning the 5s(2) S-1 and 5s5p P-1,P-3 levels in Sr-88 I, using multiconfiguration Dirac-Fock methods. Our focus is on the P-3(2) meta-stable level, which has been shown to be extremely useful in atom cooling and trapping experiments. The lifetime for this level from our work (1071 s) agrees very well with a previous theoretical value, but not with the ava
Thirty-three groups of guinea pigs, consisting of five animals in each group, were exposed to a simulated impact noise with peak levels ranging between 119.5 and 134.5 dB SPL. By varying the repetition rate, different equivalent levels could be set at each peak level. The equivalent levels ranged from 96 to 117 dB SPL, and the exposure duration was 1.5 to 24 hours. The compound action potential th
This chapter compares active inclusion strategies in five European cities with high problem pressure. The focus is on minimum income protection with particular attention paid to social assistance as well as to activation policies and the role of the third-sector in providing support and services. The local active inclusion strategies studied diverge substantially regarding the level of market-orie
The development of tools to help cities and water utility authorities communicate and plan for long-term sustainable solutions is of utmost importance in the era of a changing and uncertain climate. This study introduces a hybrid modeling concept for the cosimulation of mesoscale blue-green stormwater systems and conventional urban sewer networks. The hybrid model successfully introduces the reten
Increasing soft error rates for semiconductor devices manufactured in later technologies enforces the use of fault tolerant techniques such as Roll-back Recovery with Checkpointing (RRC). However, RRC introduces time overhead that increases the completion (execution) time. For non-real-time systems, research have focused on optimizing RRC and shown that it is possible to find the optimal number of
2-(2-nitro-1H-imidazol-1-yl)-N-(2,2,3,3,3-pentafluoropropyl)-acetamide labeled with [F-18]-fluorine ([F-18]EF5), a promising tracer for tumor hypoxia, has previously been synthesized in low yields and low specific radioactivity. In pharmacokinetic evaluations, in the presence of non-radioactive EF5, a uniform and low background uptake and high in vivo stability of [F-18]EF5 have been demonstrated.
The macroscopic properties of metallic materials depend on the state of the grain microstructure. Recrystallization acts as one of the most important mechanisms in the evolution of the microstructure and hence also of the macroscopic properties. This paper presents a mesoscale model of microstructure evolution due to recrystallization, based on a level set formulation employed in a finite element
Background: Little is known of the association between thyroid hormones in the central nervous system and Alzheimer's disease (AD). We determined thyroid hormone levels in serum and cerebrospinal fluid (CSF) in a well-defined homogeneous mono-center population. Methods: Fifty-nine consecutive patients under primary evaluation for cognitive impairment were recruited. The participants included patie
Adsorption of titanyl phthalocyanine (TiOPc) on rutile TiO2(110) modified by a set of pyridine derivatives (2,2'-bipyridine, 4,4'-bipyridine, and 4-tert-butyl pyridine) has been investigated using synchrotron radiation based X-ray photoelectron spectroscopy (XPS). For the unmodified TiOPc/TiO2 system, a strong charge transfer is observed from the first layer TiOPc into the substrate, which leads t
