In this paper, I put forward an argument that sustainability science can make objectively grounded normative claims about what courses of action society should pursue in order to achieve sustainability. From a survey of the philosophy of science, social theory and sustainability science literature, I put forward an approach to justifying these normative arguments. This approach builds on the insig

The IEEE 802.11 standard, often referred to as Wi-Fi, underpins wireless networking applications around the world that impact our daily lives, such as wireless access to the Internet from offices, homes, airports, hotels, restaurants, trains, and aircraft. Today's laptops, tablets, and smartphones are typically equipped with at least one IEEE 802.11 radio. IEEE 802.11 standards have enabled a whol

Engaging students in active participation and collaborative learning is an important pedagogical component of teaching and learning in higher education. Teachers use a variety of activities to engage students, such as interactive lectures, presentations, group activities, and projects. A metaphorical understanding of the teaching-learning process may help in the implementation of innovative and gr

Wooden casks were used extensively to transport goods in medieval Europe but have beenlargely overlooked in Scandinavian marine archaeological studies. We present a study ofcasks recovered from the Danish-Norwegian royal flagship Gribshunden, which sank inthe summer of 1495 outside Stora Ekö Island in southeastern Sweden. Duringexcavations in 2020–2021, archaeologists recovered 135 wooden staves a

Study objectives: Following traumatic events, people frequently experience distressing, involuntary memories of them (i.e., intrusions). Accumulating evidence suggests that sleep facilitates voluntary memory retrieval by supporting memory consolidation, but it is less clear what effect sleep has on intrusions. Recent research has used distressing film clips as a proxy for traumatizing events and e

Interactions between biomolecules are ubiquitous in nature and crucial to many applications including vaccine development; environmentally friendly textile detergents; and food formulation. Using small angle X-ray scattering and structure-based molecular simulations, we explore protein–protein interactions in dilute to semi-concentrated protein solutions. We address the pertinent question, whether

Background: Quantification of tumor burden from bone scan in the form of automated Bone Scan Index (aBSI) has been validated as an imaging biomarker for patients with prostate cancer. Positron emission tomography combined with computed tomography (PET/CT) is more sensitive and accurate compared to conventional imaging such as bone scan. The evaluation of medical images including PET/CT is challeng

The significance of systemic chemotherapy (SCT) combined with hepatic arterial infusion (HAI) chemotherapy in the treatment of pancreatic ductal adenocarcinoma with liver metastases (PACLM) remains unclear. Based on previous studies, this single-center propensity score matching (PSM) study aimed to explore the efficacy of SCT with or without HAI for PACLM.

We studied the effect of the human diving response, defined as bradycardia and reduced peripheral blood flow, on arterial hemoglobin desaturation. We induced a diving response of different magnitudes by using apnea in air and apnea with face immersion. Each of 21 subjects performed five apneas in air and five apneas with face immersion in 10 degrees C water. Periods of apnea in both conditions wer

The aim of this study was to compare apneic time with the human diving response, defined as heart rate (HR) reduction and reduced skin blood flow, in groups with varying degrees of breath-hold diving experience. Apneic time and HR reduction at apneas in air and apneas with face immersion in cold water were thus recorded in nine groups. Skin capillary blood flow was recorded in six of the groups. A

The effects of lung volume and involuntary breathing movements on the human diving response were studied in 17 breath-hold divers. Each subject performed maximal effort apnoeas and simulated dives by apnoea and cold water face immersion, at lung volumes of 60%, 85%, and 100% of prone vital capacity (VC). Time of apnoea, blood pressure, heart rate, skin capillary blood flow, and fractions of end-ex

Human breath-hold divers usually perform a series of dives with short intervals. Repeated apneas prolong apneic time, and an accentuated diving response has been suggested to be the cause. The aim of this study was to investigate the effect of repeated apneas on apneic time and diving response in humans. Forty-one subjects performed a series of five apneas with face immersion in water of 10 degree

Universal Design for Learning (UDL) is considered an approach to include all students in the university. UDL is based on three main principles providing multiple means of Engagement, multiple means of representation, and multiple means of action and expression. It is relevant for teachers and departments to focus on more flexibility for students to get the required information, expressing their th

The present dissertation explores students’ perception of their own readiness for higher education and students’ study related relations and the effect on academic outcome. The complexity of student engagement and academic success means that it is relevant to conduct in-depth studies of particular student populations, to explore how certain factors play out in that specific context. First, student

In this paper, we present a simple theoretical, steady-state equilibrium, predator-prey model for the joint management of marine mammals and a fish species. As an empirical case, we choose cod and grey seals in the Nordic-Baltic Sea countries, and several benefits and costs related to the latter are considered. We show that the optimal grey seal population is much lower than the actual population,
