Cement är ett viktigt byggmaterial inom anläggnings- och geoteknik. Men dess tillämpningar för stabilisering av marina sediment behöver ytterligare undersökas. Denna artikel undersöker effekterna av olika mängder portlandcement tillsatt till sedimentprover vid urlakning av tributyltenn (TBT) från det förorenade marina sedimenterar och utvärderar pH-nivån. Identifiera de bästa kombinationerna av Po
Att vara soldat är väldigt fysiskt krävande, det viktigt att upprätthålla en god fysisk kapacitetsnivå för att klara sin tjänst. Vid militära operationer arbetar soldater på lägre fysiska kravnivåer under lång tid för att ibland gå upp på intensiva kravnivåer. Framgång vid militära operationer är ofta beroende på soldaternas fysiska kapacitet, rörlighet och förmågan att bära sin utrustning. Det är
Resilience and gender have become new buzzwords for expressing renewal in peacebuilding. This article unpacks the gender-resilience nexus in theory and analyses global trends and variation in peacebuilding policy and practice. It advances an analytical framework based on three central pillars of peacebuilding: process, outcome, and expertise. A comprehensive analysis of 49 international peacebuild
In delay eye blink conditioning, the conditioned stimulus (CS) ends at the time of the unconditioned stimulus (US). If the CS duration is decreased, there will be a 'trace' period with no ongoing CS before the onset of the US. During this period some neural activity has to continue after the CS offset to: (i) permit association between the CS and the US; and (ii) elicit a conditioned response appe
1. Lesions of the cerebellar cortex can abolish classically conditioned eyeblink responses, but some recovery with retraining has been observed. It has been suggested that the recovered responses are generated by the intact contralateral cerebellar hemisphere. In order to investigate this suggestion, bilaterally acquired conditioned responses were studied after the unilateral blockade of cerebella
To fulfill the increasing demand for high-speed electronics used for computation or communication is one everlasting challenge for the semiconductor industry. Emerging fields such as quantum computation also has a need for circuits operating at cryogenic temperatures. The metal-oxide-semiconductor field-effect transistor (MOSFET) is the main component in modern electronics, traditionally fabricate
Climbing fibers, which originate in the inferior olive and project to Purkinje cells and Golgi cells in the cerebellar cortex, were activated at low (0.4-Hz) and high (4-Hz) frequencies by peri-orbital stimulation in decerebrate ferrets. Climbing fiber responses were recorded as field potentials from the c3 zone of the cerebellar surface. When periorbital stimulation was applied at high frequency,
The aim of these experiments was to obtain a detailed knowledge of how the orbicularis oculi muscle is activated during the execution of a conditioned eyeblink response (CR). This is the first critical step to understand the underlying neural mechanisms involved in the control of the CR. Decerebrate ferrets were trained in a classical conditioning paradigm. The conditioned stimulus (CS) was a trai
To study the role of the mossy fiber afferents to the cerebellum in classical eye-blink conditioning, in particular the timing of the conditioned responses, we compared the effects of varying a peripheral conditioned stimulus with the effects of corresponding variations of direct stimulation of the mossy fibers. In one set of experiments, decerebrate ferrets were trained in a Pavlovian eye-blink c
Pulmonary arterial hypertension (PAH) is a life-threatening disease characterized by vasoconstriction and remodeling of the pulmonary vessels. Risk stratification in PAH could potentially be improved by including novel biomarkers related to PAH pathobiology. We aimed to investigate the relationship between extracellular matrix (ECM)-related proteins, survival, and European Society of Cardiology an
Background: Patients with chest pain may have normal coronary arteries and suffer from microvascular angina (MVA). The aim of this study was to determine if patients with suspected MVA have lower global myocardial perfusion (global MP) during adenosine stress compared with healthy controls and coronary artery disease (CAD) patients and to determine if there are sex differences in global MP. Method
A new laboratory reactor to perform in situ studies of structural changes in wood during soda pulping using synchrotron X-ray tomography is presented. The reactor is of recirculation type to provide stable reaction conditions and mimic the industrial situation. Experiments have been performed using this reactor in situ at a synchrotron microtomography beamline to provide sequences of 3D images fro
Smart vision sensor systems enable many computer vision applications such as autonomous drones and wearable devices. These battery-powered gadgets have very stringent power consumption requirements. Close-to-sensor feature extraction compressing the full image into descriptive keypoints, is crucial as it allows for several design optimizations. First, the amount of necessary on-chip memory can be
Background: Using genetically modified plants as natural dispensers of insect pheromones may eventually become part of a novel strategy for integrated pest management. Results: In the present study, we first characterized essential functional genes for sex pheromone biosynthesis in the rice stem borer Chilo suppressalis (Walker) by heterologous expression in Saccharomyces cerevisiae and Nicotiana
Background: In hereditary angioedema (HAE), low levels (type 1) or defect in function (type 2) of the serine-protease inhibitor C1 Inhibitor protein results in activation of the classical pathway of the complement system as well as the contact system. Here, we investigated the risk of comorbidities in HAE. Methods: Individuals with HAE (n = 239; identified through a physician made diagnosis) and a
Objective: Previous research has suggested an association between physical activity (PA), joint function, and molecular biomarkers, but more studies are needed. The aim of this study was to explore the associations between PA or self-reported joint function and molecular biomarkers of cartilage and inflammation in individuals with hip and/or knee osteoarthritis (OA). Specific objectives were to ex
The bioactivity, biological fate and cytotoxicity of nanomaterials when they come into contact with living organisms are determined by their interaction with biomacromolecules and biological barriers. In this context, the role of symmetry/shape anisotropy of both the nanomaterials and biological interfaces in their mutual interaction, is a relatively unaddressed issue. Here, we study the interacti
