A study was undertaken to measure the efficiency with which carbon dioxide was stripped from freshwater (0 parts per thousand) and saline water (35 parts per thousand NaCl) passing through an air-lift at 15 degrees C. The air-lift was constructed of 50 mm (OD) PVC pipe submerged 95 cm in a tank, had an adjustable air injection rate, and could be adjusted to three lifting heights: 11,16 and 25 cm.

Currently, we are experiencing biodiversity loss on different spatial scales. One of the best studied taxonomic groups in decline is the butterflies. Here, we review evidence for such declines using five systematic studies from southern Sweden that compare old butterfly surveys with the current situation. Additionally, we provide data on butterfly and burnet moth extinctions in the region’s counti

The use of energy gases with renewable origins will become important with diminishing fossil resources. This as the infrastructure of the gaseous fuels is well built out and the distribution networks already exist. LPG is one of the most versatile fuels around, perfect for rural areas and in many other applications. The fossil origin of the fuel will, in today’s climate and environmental debate, h

This dissertation deals with the conflict between the World Alliance of Reformed Churches (WARC) - the worldwide Reformed movement - and the Dutch Reformed Church in South Africa (DRC) regarding the latter's support for and theological legitimizing of apartheid. One of the strongest measures possible was taken when the issue in 1982 was declared a Status Confessionis and the Dutch Reformed Church

Popular Abstract in Swedish Sedan introduktionen av transistorn och den integrerade kretsen har teknologin inom halvledarindustrin utvecklats i en mycket hög takt. Genom att bygga allt mindre och snabbare transistorer har en exponentiell förbättring av prestanda bibehållits sedan 1960-talet, ett fenomen känt som Moores Lag. Fram tills nyligen har utvecklingen mot högre prestanda och fler transistoSince the introduction of the transistor and the integrated circuit, the semiconductor industry has developed at a remarkable pace. By continuously fabricating smaller and faster transistors, it has been possible to maintain an exponential increase in performance, a phenomenon famously described by Moore’s Law. Today, billions of transistors are integrated on a single chip and the size of a transi

Flood risk is a great global concern that is not only affecting developing countries, but threatens to undermine sustainable development also in the most affluent advanced liberal democracies. While political inertia is delaying much needed global change, efforts to reduce risk and adapt to a changing climate are growing on more local levels. However, floods tend not to be bounded by geopolitical,

Complex formation between Pd(H2O)(4)(2+) and maleic acid (H(2)A) has been studied at 25 degrees C and 2.00 M ionic strength in acidic aqueous solution. Reaction takes place with 1:1 stoichiometry. The kinetics has been followed by use of stopped-flow spectrophotometry under pseudo-first-order conditions with maleic acid in excess. In the concentration ranges 0.01 less than or equal to [H(2)A](tot)

Background: Ethiopia is one of the sub-Saharan countries hit hard by the HIV epidemic. Previous studies have shown that subtype C dominates the Ethiopian HIV-1 epidemic, but the evolutionary and temporal dynamics of HIV-1 in Ethiopia have not been closely scrutinized. Understanding the evolutionary and epidemiological pattern of HIV is vital to monitor the spread, evaluate and implement HIV preven

Popular Abstract in Swedish Antibiotikaresistens hos pneumokocker har utvecklats till ett problem i hela världen. Interkontinental spridning av ett fåtal resistenta kloner verkar stå för den snabba ökningen av förekomsten av pneumokocker med nedsatt känslighet för penicillin (PNSP). Förekomst av PNSP har reducerat behandlingsalternativen för såväl vanliga luftvägsinfektioner som invasiva infektionPneumococcal resistance to antibiotics has become a worldwide problem. The rapid increase in frequency seems to be caused by intercontinental spread of a few resistant clones. Resistance to antibiotics in pneumococci has reduced the therapeutic arsenal for common respiratory tract infections as well as for invasive infections. Problems of specific clinical concern are meningitis due to penicillin-

Background: Informal caregivers may experience high levels burden. Prior to COVID-19, loneliness and social isolation, and especially the discordance between them, were recognized for rapid aging-related cognitive decline. The COVID-19 has significantly increased social isolation and loneliness in caregivers. Thus, we aimed to explore the variables that were associated with higher care burden amon

Understanding monthly runoff variability, its spatio-temporal characteristics, and key drivers under climate change and human impacts is crucial for long-term water resource management. However, current knowledge remains limited, especially in high-elevation, seasonally cold regions. Focusing on 10 sub-basins along an elevation gradient (1000 to 5900 ma.s.l.) in the hydrologically complex Yalong R

Medical research generates a large number of publications with the PubMed database already containing >35 million research articles. Integration of the knowledge scattered across this large body of literature could provide key insights into physiological mechanisms and disease processes leading to novel medical interventions. However, it is a great challenge for researchers to utilize this informa

The world is currently facing a biodiversity and climate crisis which are globally interlinked. Nature-based solutions (NBS), defined as “actions to protect, sustainably manage, and restore natural and modified ecosystems that address societal challenges effectively and adaptively, simultaneously benefiting people and nature” is part of the solution to these challenges. Here we give a status overv

Background: The human cerebellum has a large, highly folded cortical sheet. Its visualization is important for various disorders, including multiple sclerosis and spinocerebellar ataxias. The derivation of the cerebellar cortical surface in vivo is impeded by its high foliation. Purpose: To image the cerebellar cortex, including its foliations and lamination, in less than 20 minutes, reconstruct t

Background: Chronic kidney disease (CKD) is linked to an increased cardiovascular disease (CVD) burden. Albeit underappreciated, sex differences are evident in CKD with females being more prone to CKD development, but males progressing more rapidly to kidney failure (KF). Cardiovascular remodelling is a hallmark of CKD with increased arterial and valvular calcification contributing to CKD. However

A large and rapidly growing population in Kenya together with increasing demands put heavy pressure on the country’s resources. Primary to produce enough food but also to meet other needs such as access to timber and firewood. A large part of the population relies on yields from their own farming for their survival. The farms are generally small and the needs many which makes it important to get o

Syftet med uppsatsen är att undersöka hur familjevåld påverkar bedömningen av barnets bästa i frågor om vårdnad, boende och umgänge. Med våld avses våld riktat mot någon annan i familjen än barnet. Jag har använt mig av tre frågeställningar för att lyfta fram vilken betydelse våldet har för barnet. Den första frågeställningen är mer övergripande och handlar om hur våldet påverkar barnets bästa. DeThe aim of this thesis is to examine how domestic violence affects the decision of what is in the best interest of the child with regards to parental authority judgments. In this thesis the term domestic violence refers to all violence towards another family member except the child himself. The thesis is built upon three questions in order to highlight the impact domestic violence has upon the dec

Issue of study For the past ten years there has been a remarkable growth in the wind power industry. During 2003 - 2010 the production capacity increased by 456 % in Sweden, corresponding to total capacity of 2019 MW. An additional 754 MW was installed in 2011, and there is a planned capacity installation of 950 MW for 2012. This will, according to a prognosis from Svensk Vindenergi, generate a po

På senare år har utvecklingen av artificiell intelligens (AI) gått i raketfart och AI-verktyg som kan användas för avancerade kognitiva och perceptuella uppgifter dyker upp i alla områden av livet. Det tog inte lång tid innan det även insågs att AI kunde användas inom litteraturen och konsten. På sekunder kan avancerade litterära och konstnärliga verk numera åstadkommas med ett enkelt knapptryck,
