Populärvetenskaplig sammanfattning: En sedimentsekvens från sjön Svartkälstjärn i Västerbotten provtogs för pollen- och sporanalys samt kolpartikelanalys. Sedimentens ålder bestämdes med 14C-dateringar och spår av radioisotopen 137Cs, som indikerar modern tid då de återspeglar provsprängningarna av kärnvapen under senare delen av 1900-talet. Dateringarna visar att sedimentationen i sjön började föA 2.1-m sediment sequence retrieved from Lake Svartkälstjärn, located at 260 m a.s.l. in the province of Västerbotten, Sweden, was subsampled for pollen and spore analysis, charcoal analysis, and influx calculations. The aim was to establish the local environmental development during the Holocene with focus on forest composition, fire frequency, soil erosion, aquatic production, and human impact.

Objective. Our hypothesis states that the reactivity of the cutaneous microcirculation is reduced in patients with hypertension compared with healthy subjects. The objective was to verify the hypothesis by measuring microvascular function in hypertensive patients. Design. The study was a controlled trial with two arms: 15 hypertensives and 15 normotensives were enrolled, aged 30-60 years, and in h

This article deals with Gerhard Oestreich's concept of 'Sozialdisziplinierung' and its possible status as a challenger to the two main schools within the Swedish state of research concerning the Early Modern state-building process. These main streams in Swedish historical research concists of the Interventionists, who argue for the state's more or less brutal intervention in the local autonomous s

With timely allocated movement phases, mobile organisms can match their space-use with the seasonality of the environment and thereby optimise their resource utilisation over time. Long-distance avian migrants are known to move with the seasonal dynamics on an annual basis, but how individuals respond to seasonality within their tropical non-breeding range has been less studied. Here we analyse th

Background: Temperature is considered as a significant determinant of skeletal muscle function and also a predisposing factor for muscular mechanical performance. Yet, the effects of local cooling on neuromuscular function and performance during gait remain unexamined.Objectives: To investigate the effects of local cooling on lower leg muscles’ isometric maximal force production, electromyography

OBJECTIVES:: Individuals with chronic pain often report increased pain sensitivity compared to pain free individuals, so it is crucial to determine if and how different pain characteristics influence or interact with pain sensitivity. An alternative to experimental pain sensitivity testing is the self-reported pain sensitivity questionnaire (PSQ), that captures pain sensitivity in various body are

Ecotourism is the concept of traveling responsibly to natural areas where the environment and the well-being of the local people are sustained, where the economic profit is reinvested in the area and where knowledge is communicated to decrease visitor impact and maintain the local environment. Ecotourism is the fastest growing segment of the global tourism industry and therefore it is important to

This research aims to bring a better understanding on the challenges of the current education policy in Ethiopia. The current education policy in Ethiopia has been developed to bring a desirable quality education, yet education quality in Ethiopia is getting worse. Here one can assume that there are several factors contributing to the education policy gaps which quensiquently end up in low educati

This thesis offers a cultural analysis of climate change, modernisation and sustainable development in the pastoral landscape of Baringo, Northern Kenya. For the majority of the pastoralists living there, life is defined by crippling poverty, ethnic violence and an increasingly erratic and unpredictable climate. In response, a growing number of people have moved away from the traditional reliance

Rapid development in urban areas of maritime countries may need solutions to address scarcity of land for development and infrastructure. Land reclamation has been an option in many maritime countries, including in Malaysia to overcome this problem. Tanjung Tokong Land Reclamation Project is an ongoing development project in Penang, Malaysia, where housing and commercial properties are constructed

Context. Tidal interactions between massive galaxies and their satellites are fundamental processes in a universe with a λ cold dark matter (λ CDM) cosmology, and they redistribute material into faint features that preserve records of past galactic interactions. While stellar streams in the Local Group impressively demonstrate satellite disruption, they do not constitute a statistically significan

Purpose: Direct percutaneous access to the carotid artery (diPerCa) during endovascular aortic arch repair (EVAAR) can potentially present a minimally invasive access with lesser local adverse events. Techniques: A retrospective review of consecutive EVAAR between January 2018 and January 2024, in a tertiary referral center, was performed to identify cases, in which diPerCa was used. Patients who

BACKGROUND: In patients with non-invasive urothelial carcinoma of the prostatic urethra (PUC), treatment with Bacillus Calmette-Guérin (BCG) could be beneficial. OBJECTIVE: To assess the response rates to BCG in the different tumor stages, to describe the clinical impact of transurethral resection of the prostate (TURP) before BCG treatment, and to review the side effects of BCG treatment for PUC.

Climate change is estimated to increase the risk of the bark beetle (Ips typographus L.) mass outbreaks in Norway Spruce (Picea abies (L.) Karst) forests. Habitats that are thermally suitable for bark beetles may expand, and an increase in the frequency and intensity of droughts can promote drought stress on host trees. Drought affects tree vigor and in unison with environmental features it influe

Purpose: Childhood cancer is rare, and treatment is frequently associated with long-term morbidity. Disparities in survival and long-term side effects encourage the establishment of networks to increase access to complex organ-conservative strategies, such as brachytherapy. We report our experience of an international cooperation model in childhood cancers. Methods and Materials: We examined the o

Transurethral resection of the prostate, or other methods to decrease outlet resistance usually leads to relief of symptoms in patients with bladder outlet obstruction (BOO). If symptoms of underactivity persist after normalization of outflow conditions, treatment options are limited. In this review, we hypothesize, based on results from basic research, what might become treatment options for such

The drinking water and sanitation systems (WSS) in rural Kazakhstan have since its independence in 1991 been challenged with deteriorating implemented centralized systems where the population has been forced to explore individual, decentralized options to ensure a drinking water supply. With a limited documentation and classification of current WSS operating in rural settlements, the large-scale w

Freshwater ecosystems in the central Andes provide critical ecosystem services (ES), including water purification, baseflow regulation, groundwater recharge, and cultural and recreational benefits. However, these high-mountain systems are increasingly threatened by changing land use, climate variability, and accelerating pressure on water resources.
