Evaluation air void content of drilled porous asphalt mixture cores using non-destructive X-ray computed tomography

Tomography technology is not usual when investigating drilled asphalt cores properties. Currently, there is no internationally recognised standard tomography method for asphalt pavements. Tomography provides, however, a non-destructive alternative to traditional, usually destructive, testing of drilled cores. Furthermore, tomography offers possibilities, which traditional laboratory analyses do no

The Tenure Track Model : Its Acceptance and Perceived Gendered Character

This article is concerned with the tenure track (TT) model, which has become increasingly used to extend the period of early career academics’ probation from one to five years across the EU. This article focuses on the TT in Trinity College Dublin (TCD), the oldest and most prestigious university in Ireland, one where gender equality has been embedded more consistently and where the pace of change

Clean water using solar and wind : Outside The power grid

Solar photo-voltaic (PV) and wind offer to bring both clean energy and clean water to remote regions and peri-urban areas in the world, outside the conventional electric grids. One out of seven people has no electric power available that would bring light to the home, cook the food, pump to access water and purify or re-use it. Off-grid systems are scalable and can be designed to any size, from ho

The Complete Larval Development of the Pedunculated Barnacle Capitulum mitella (Crustacea: Cirripedia) Using a Standardized Terminology

We describe the complete larval development of the pedunculated barnacle Capitulum mitella, using both light microscopy and scanning electron microscopy. This includes all six naupliar instars and the final cypris stage. Many previous accounts on the development of barnacle larvae suffer from a shortage in detail and habitually use terminologies that are either inconsistent or hard to compare with

Influence of rotation speed and frequency on the decision of Columba livia domestica (homing pigeon) to cross the rotor-swept area of paper blades mimicking a wind turbine

To reduce bird collisions with wind turbines, automatic detection systems have been developed to slow the blades down when a bird is approaching. We experimentally tested whether blade rotational speed (i.e., number of rotations per min) and frequency (i.e., number of times a blade passes a point per min) affected the decision time (i.e., time to take-off), path choice (i.e., the position in the a

Female reed warblers in social pairs with low MHC dissimilarity achieve higher MHC dissimilarity through random extra-pair mating

Major Histocompatibility Complex (MHC) polymorphism is maintained by balancing selection through host-pathogen interactions and mate choice. MHC-based mate choice has been investigated across a wide range of vertebrates, and an established concept is that females should choose a mate with an MHC genotype that is dissimilar to her own to ensure high MHC divergence in her offspring. Here we present

Achieving a healthy indoor environment by using an emissions barrier to stop the spread of chemicals from a building into the indoor air

An emissions barrier was used in a premises due to complaints about the indoor air quality (IAQ) as a result of emissions from the building in question. The emissions comprised chlorophenols/chloroanisoles and polycyclic aromatic hydrocarbons (PAH) from treated wood and volatile organic compounds (VOCs), mainly 2-ethylhexanol, from polyvinyl chloride (PVC) flooring and the glue used to paste the f

Ontology and Social Influence in Language Learning Psychology : A Theoretical Review Through the Lens of Dialogical Self Theory

In applied psychology, ontological assumptions are rarely subjected to scrutiny. Yet ontological positionings will affect all aspects of a research undertaking. Assumptions about what is real—and what is not—will affect conceptualization, study design, and analytical focus. In the investigation of social influence, failure to engage with ontological positionings has resulted in a default ontology

THE BORG SCALE IS SAFE AND EFFICACIOUS FOR PRESCRIBING AND MONITORING SELF-ADMINISTERED BALANCE AND RESISTANCE EXERCISE IN PATIENTS WITH CHRONIC KIDNEY DISEASE : A POST-HOC ANALYSIS OF RENEXC, A RANDOMIZED CONTROLLED TRIAL

Objective: To evaluate the safety, adherence, and efficacy of self-administered balance and resistance exercise using the Borg scale in patients with chronic kidney disease, and to examine relationships between exercise intensity or duration and baseline measures, and relationships between change in physical performance and baseline measures, intensity, or duration. Design: Post-hoc analysis of a

Thiazole orange : a complement to established methods for diagnosing inherited dense granule defects

What is the context?: Platelets contain three major types of granules (alpha granules, dense granules and lysosomal granules) that carry distinct cargo. Dense granules store small molecules such as calcium, serotonin and adenosine 5′-diphosphate (ADP) that are essential for platelet activation and aggregation. Impaired production or release of dense granules can affect blood clotting and cause inc

Characterizing the onset and progression of Alzheimer’s pathologies using amyloid and tau PET imaging and plasma p-tau217

Characterizing the onset and progression of Alzheimer’s disease pathologies relative to one another is important for biological staging and clinical trial design. Recent advances in blood plasma assays of Alzheimer’s disease amyloid and tau pathology have enabled detection of Alzheimer’s disease pathophysiology during life, but it remains unclear when plasma biomarker abnormalities are detectable

Multi-Objective MILP Models for Optimizing Makespan and Energy Consumption in Additive Manufacturing Systems

Additive manufacturing (AM) is revolutionizing industrial production by enabling the fabrication of complex, customized components with reduced material waste. However, the scheduling of AM machines presents significant challenges in terms of optimizing both time-related performance and energy consumption. This paper introduces a novel multi-objective mixed-integer linear programming (MILP) model

Exploring the Relationship Between Rescue Service Response Times, Citizen Satisfaction and Ownership of Fire Safety Equipment in Sweden

This study investigates how rescue service response times and staffing solutions relate to both citizen satisfaction with rescue services and the adoption of individual fire safety measures in Sweden. Data were drawn from Statistics Sweden's satisfaction index, rescue service response times from KOLADA, and survey data from the Swedish Civil Contingencies Agency on ownership of functional smoke de

Evolutionary Social Sciences—An Interdisciplinary Fringe Project or a Small Revolution?

In many research fields of the social sciences, attempts have been and are being made to integrate Darwinian evolutionary theory into their own work. The motivation and benefits of integration can vary from field to field and range from considering biological foundations for social phenomena to the application of methods and study designs from outside the field. Furthermore, Darwinian evolutionary

Intestinal Lymphangiectasia

Endoscopically, the villi of the small bowel in intestinal lymphangiectasia typically appear white and may be swollen. Less commonly, tiny white spots are visible in the mucosa. The whitish discoloration of the villi is caused by chylomicrons, which accumulate in and obstruct the dilated lymphatic capillaries. These changes can also be demonstrated histologically. Lymphangiectasia is characterized

Network Analysis

Network analysis has been recently adopted by the field of psychology to explore networks of symptoms in psychopathology, and wider interactive networks of biological, behavioral, and psychological factors influencing mental health. The network theory of psychopathology conceptualizes symptoms of mental disorder as causally connected, rather than being caused by disease or an underlying latent var

Integrating sustainability assessments to facilitate decision making in sustainable water management in agriculture

Agricultural production necessitates sustainable practices to ensure long-term and sustained food security. Water is a key ingredient for food production. Ensuring sustainable water management in agriculture is thus essential for global wellbeing. But how do we make sure that our practices are sustainable? A large variety of sustainability assessments abound. Their results may even show conflictin

BIOLOGILÄRARES FÖRSTÅELSE AV DET NORMMEDVETNA ARBETET I SEXUALUNDERVISNINGEN

Sex and social norms have always existed throughout human history, and are communicated through institutions such as schools, religion, and culture, making them an integral part of everyday life. However, this does not necessarily mean that we are aware of the different kinds of norms and sexuality. This study aims to explore the experiences of biology teachers in grades 7-9 who work in sexuality
