Book Review: Animal Rights Activism: A Moral–Sociological Perspective on Social Movements

In recent social movement studies a symbolic framework emphasizing rituals, symbols and master frames has contributed with important insights into the diverse communicative and socio-cultural aspects of contemporary social movements (Alexander, 2006; Benford and Snow, 2000; Jasper, 1997). With the publication of Animal Rights Activism: A Moral–Sociological Perspective on Social Movements a complem

Cognitive and neural mechanisms of inflectional morphology processing : Studies of native speakers and second language learners of Swedish

The present dissertation investigates inflectional morphology processing in native speakers and second language (L2) learners of Swedish. Results of Study 1 suggest that two separate neural mechanisms might be available for native comprehension of inflected words, as reflected in event-related brain potentials obtained for visually presented verb forms. Overregularized verbs (e.g. *bär+de ‘bear +

Heat flux in metal cutting : Experiment, model, and comparative analysis

In this paper, a proof of time-dependent behavior of heat flux into a cutting tool is built. Its implementation calls for a new method for estimating heat flux, which was developed using an inverse problem technique. A special experimental setup was designed and manufactured to implement the method. A series of dry machining experiments were conducted with high speed steel and cemented carbide too

Predictable evolution towards larger brains in birds colonizing oceanic islands

Theory and evidence suggest that some selective pressures are more common on islands than in adjacent mainland habitats, leading evolution to follow predictable trends. The existence of predictable evolutionary trends has nonetheless been difficult to demonstrate, mainly because of the challenge of separating in situ evolution from sorting processes derived from colonization events. Here we use br

Hole-quality evaluation in drilling fiber-reinforced composites

This paper presents a novel approach for a complex evaluation of the quality of drilled holes in fiber-reinforced composite materials. The proposed methodology is based on non-destructive quantification of visible defects based on the numerical analysis of drilled hole images. Automatic contour definition and profile formation for the uncut fibers and delamination were implemented via modularized

Modulation of antibiotic resistance and induction of a stress response in Pseudomonas aeruginosa by silver nanoparticles

The objective of this study was to characterize the effects of silver nanoparticles on Pseudomonas aeruginosa. Their interactions with several conventional antibiotics and ability to induce a stress response were examined. Interactions between silver nanoparticles (AgNPs) and antibiotics against free-living cells and biofilm of P. aeruginosa were studied using the chequerboard method and time-kill

Place-based innovation policy for industrial diversification in regions

New industrial innovation policies like smart specialization aim at boosting economic growth by diversification towards more complex and higher value economic activities. This paper proposes a conceptual and analytical framework to support the design and implementation of such policies considering place-specific preconditions, particularly the differentiation of the regional system of innovation a

The spatial range of protein hydration

Proteins interact with their aqueous surroundings, thereby modifying the physical properties of the solvent. The extent of this perturbation has been investigated by numerous methods in the past half-century, but a consensus has still not emerged regarding the spatial range of the perturbation. To a large extent, the disparate views found in the current literature can be traced to the lack of a ri

Rice starch particle interactions at air/aqueous interfaces-effect of particle hydrophobicity and solution ionic strength

Starch particles modified by esterification with dicarboxylic acids to give octenyl succinic anhydride (OSA) starch is an approved food additive that can be used to stabilize oil in water emulsions used in foods and drinks. However, the effects of the OSA modification of the starch particle on the interfacial interactions are not fully understood. Here, we directly measured the packing of films of

Measurement of inclusive jet and dijet cross-sections in proton-proton collisions at √s=13 TeV with the ATLAS detector

Inclusive jet and dijet cross-sections are measured in proton-proton collisions at a centre-of-mass energy of 13 TeV. The measurement uses a dataset with an integrated luminosity of 3.2 fb−1 recorded in 2015 with the ATLAS detector at the Large Hadron Collider. Jets are identified using the anti-kt algorithm with a radius parameter value of R = 0.4. The inclusive jet cross-sections are measured do

Nanoparticle-supported polymer brushes for temperature-regulated glycoprotein separation : Investigation of structure-function relationship

In this work, we synthesized a series of nanoparticle-supported boronic acid polymer brushes for affinity separation of glycoproteins. Polymer brushes were prepared by surface-initiated atom transfer radical polymerization of glycidyl methacrylate and N-isopropylacrylamide, followed by stepwise modification of the pendant as well as the end functional groups to introduce boronic acid moieties thro

The Earth's Magnetic Field and Visual Landmarks Steer Migratory Flight Behavior in the Nocturnal Australian Bogong Moth

Like many birds [1], numerous species of nocturnal moths undertake spectacular long-distance migrations at night [2]. Each spring, billions of Bogong moths (Agrotis infusa) escape hot conditions in different regions of southeast Australia by making a highly directed migration of over 1,000 km to a limited number of cool caves in the Australian Alps, historically used for aestivating over the summe

Improved Prognosis and Low Failure Rate with Anticoagulation as First-Line Therapy in Mesenteric Venous Thrombosis

Background Monotherapy with anticoagulation has been considered as first-line therapy in patients with mesenteric venous thrombosis (MVT). The aim of this study was to evaluate outcome, prognostic factors, and failure rate of anticoagulation as monotherapy, and to identify when bowel resection was needed.Methods Retrospective study of consecutive patients with MVT diagnosed between 2000 and 2015.RBACKGROUND: Monotherapy with anticoagulation has been considered as first-line therapy in patients with mesenteric venous thrombosis (MVT).

Consumer Perspectives on longevity and Reliability : A National Study of Purchasing Factors Across Eighteen Product Categories

Increasing global demand for durable goods prevents the decoupling of economic growth from natural resource use required to achieve sustainable consumption and production. Presently, most consumers in the United Kingdom (UK) exhibit a strong preference for purchasing new durable goods. Therefore, short-to-medium term strategies that seek to engender sustainable consumption of durable goods should
