Urban water systems and, in particular, wastewater treatment facilities are among the major energy consumers at municipal level worldwide. Estimates indicate that on average these facilities alone may require about 1% to 3% of the total electric energy output of a country, representing a significant fraction of municipal energy bills. Specific power consumption of state-of-the-art facilities shoul
Background: Umbilical and epigastric hernia repairs are frequently performed surgical procedures with an expected low complication rate. Nevertheless, the optimal method of repair with best short- and long-term outcomes remains debatable. The aim was to develop guidelines for the treatment of umbilical and epigastric hernias. Methods: The guideline group consisted of surgeons from Europe and North
Current large-scale deforestation poses a threat to ecosystems globally, and imposes substantial and prolonged changes on the hydrological and carbon cycles. The tropical forests of the Amazon and Indonesia are currently undergoing deforestation with catastrophic ecological consequences but widespread deforestation events have occurred several times in Earth's history and these provide lessons for
Artikel om den amerikanska historiens betydelse som politisk kraft.
This book discusses in detail how Orthodox Christianity was involved in and influenced political transition in Ukraine, Serbia, and Georgia after the collapse of communism. Based on original research, including extensive interviews with clergy and parishioners as well as historical, legal, and policy analysis, the book argues that the nature of the involvement of churches in post-communist politic
Perovskite solar cells are among the most exciting photovoltaic systems as they combine low recombination losses, ease of fabrication, and high spectral tunability. The Achilles heel of this technology is the device stability due to the ionic nature of the perovskite crystal, rendering it highly hygroscopic, and the extensive diffusion of ions especially at increased temperatures. Herein, we demon
This paper deals with the real-time implementation of feedback controllers. In particular, it provides an analysis of the stability property of closed-loop systems that include a controller that can sporadically miss deadlines. In this context, the weakly hard m-K computational model has been widely adopted and researchers used it to design and verify controllers that are robust to deadline misses
The article is a comparative inquiry into the roles of Ilia Chavchavadze (1837-1907) and Taras Shevchenko (1818-1861) as national poets and anti-tsarist intellectuals within the context of their respective national traditions (in Georgia and Ukraine). During the period of their activity (19th and the beginning of 20th century), both Ukraine and Georgia were under tsarist imperial rule (albeit the
Since the Rose Revolution (2003), Georgia has encountered an unprecedented scale of institutional reforms concomitant with the rise of American and European involvement in the “democratization” process. Various scholars have suggested that Georgian nationalism developed from an ethno-cultural basis to a more civic/liberal orientation after the Rose Revolution. This paper analyzes Georgian national
In their natural environments, organisms are unlikely to be distributed randomly but instead they are constantly faced with multiple and variable threats. In order to maximise survival, they need to be able to perceive the present threat level and respond accordingly. In aquatic ecosystems, two common threats for crustacean zooplankton are predation and ultraviolet radiation (UVR). Despite the gro
Purpose of ReviewIt is important to examine what effect sleep has after an emotional experience. More knowledge about this topic could help inform us whether there are any potential sleep interventions that could help make sure that memories of negative emotional experiences are processed in the most adaptive manner possible.Recent FindingsFindings on the role of sleep in altering reactivity to em
The Learning with Errors (LWE) problem is one of the main mathematical foundations of post-quantum cryptography. One of the main groups of algorithms for solving LWE is the Blum-Kalai-Wasserman (BKW) algorithm. This paper presents new improvements for BKW-style algorithms for solving LWE instances. We target minimum concrete complexity and we introduce a new reduction step where we partially reduc
Protein-based drugs often require targeted drug delivery for optimal therapy. A successful strategy to increase the circulation time of the protein in the blood is to link the therapeutic protein with an albumin-binding domain. In this work, we characterized such a proteinbased drug, GA-Z. Using asymmetrical flow field-flow fractionation coupled with multi-angle light scattering (AF4-MALS) we inve
Evidence-based software engineering (EBSE) aims to improve research utilization in practice. It relies on systematic methods (like systematic literature reviews, systematic mapping studies, and rapid reviews) to identify, appraise, and synthesize existing research findings to answer questions of interest. However, the lack of practitioners' involvement in the design, execution, and reporting of th
Kompendiet är framtaget för att användas som lärobok i murverkskonstruktion på grundnivå på civil- och högskoleingenjörsutbildningar. Kompendiet behandlar dimensionering och konstruktiv utformning av murverkskonstruktioner i enlighet med Eurokod 6 samt den svenska nationella bilagan EKS 11 och kan därmed även användas av yrkesverksamma konstruktörer. För en mer uttömmande hantering av konstruktion
Strengthening of masonry walls is a means to improve the energy performance of modern external masonry walls without further increasing their total thickness. The present paper evaluates the feasibility - here refer-ring to ease-of-application and structural performance - of several techniques aimed at strengthening mason-ry walls subjected to eccentric axial loading. Four full scale walls made of
EUs Energieffektiviseringsdirektiv innebär en skärpning av kraven på byggnaders energiprestanda. För murverksbranschens del har man identifierat ett behov av att utveckla ytterväggskonstruktioner med 30 procent lägre U-värde jämfört med idag vanligt förekommande murade ytterväggslösningar. Utveckling av välisolerade murade ytterväggskonstruktioner med tunna, ytförstärkta bärande delar förefaller v
