Wave activity on the sea-bed of the english channel
No full textLong-term surface wave records from various parts of the English Channel are used to determine the percentage of time during a year for which waves disturb the sea-bed. Most of the bottom sediments are rarely disturbed by waves (<1% of the time), due to water depth and sediment grain size. The coastal zones (<30 m), including the embayments, experience significant wave disturbance at the sea-bed (i.e. >5–10%). The general distribution of surficial sediments can be explained in terms of tidally-induced processes alone. Even in areas where wave activity is high, fine-grained sediment transport is controlled by the same mechanisms
Price Personalization versus Contract Terms Personalization: Mapping the Complexity
No full textThe chapter aims to map the place of price personalization against the broader
conceptual backdrop of personalization practices in consumer law. In so doing, it looks both into the general theoretical framework of personalization and into some
specific instances where other contract terms intertwine with price personalization

Postanal lateral groups of setulae with distalmost seta longer than others; in distalmost groups, length of setulae less than width of postabdominal claw base; unlike in most Aloninae, distalmost group of setulae located at significant distance from the end of postabdomen. Postabdominal claw moderately long, almost straight, with long basal spine. Antennule without lateral aesthetascs, all terminal aesthetascs of similar length. Antennal seta without basal peg. Antenna with thin seta on basal segment of endopodite. Spine on basal segment of exopodite of similar length than middle segment. Spines on apical segments longer than apical segments. IDL of limb I with three setae (Fig. 15 M), seta 1 short, setae 2–3 thin, armed with thin setulae. Single species, Oxyurella singalensis (Daday, 1898) (Fig. 15 I–M). Length of adult 0.55–0.85 mm. Common species, found in lakes, ponds, reservoirs, slow rivers and paddy fields. Littoral species, associated with vegetation. Indo-Malaysian species.

Turbulent and macro-turbulent structures developed in the benthic boundary layer downstream of topographic features
No full textThe characteristics and effects of large-scale flow structures developed in the benthic boundary layer downstream from large topographic features were analysed throughout a tidal cycle. The observed signature of the macro-turbulent features consisted of streamwise modules of low horizontal velocity and high suspended sediment concentration (SSC), alternating with modules of high horizontal velocity and low SSC. These modules extended 10 to 20 m streamwise and exceeded 1 m vertically, and are believed to be related to flow separation effects over large bedforms upstream of the deployment site. The macroscale flow modules intensified the ‘ burst-like ’ turbulent events and favoured sediment transport. ‘ Ejection-like ’ events were magnified during modules of decreasing horizontal velocity and increasing turbidity, whereas ‘ sweep-like ’ events were magnified during modules of increasing horizontal velocity and decreasing SSC. The enhanced turbidity of the macroscale modules may be the result of enhanced upward diffusion of sediment by ejection events, whereas the low-turbidity modules may be induced by increased downward transport of suspended sediment by sweep events. These hypotheses were supported by cross-spectral analysis performed on velocity and suspended sediment concentration time-series recorded at the site. An enhanced (negative) contribution of outward and inward interaction events to the Reynolds stress, compared to those reported in uniform BBLs, resulted in ‘ abnormally ’ low stress values

Algorithmic Transparency and Explainability for EU Consumer Protection: Unwrapping the Regulatory Premises
No full textThe principles of transparency and explainability are landmarks of the current EU approach to artificial intelligence. Both are invoked in the policy guidelines as values governing algorithmic decision-making, while providing rationales for existing normative provisions, on information duties, access rights and control powers. This contribution addresses the debate on transparency and explainability from the EU consumer market perspective. The consumers’ position relative to algorithmic decision-making is considered, and their risks concerning mass surveillance, exploitation, and manipulation are discussed. The concept of algorithmic opacity is analyzed, distinguishing technology-based opacity that is intrinsic to design choices, from relational opacity toward users. The response of EU law is then considered. The emerging approach to algorithmic transparency and explainability is connected to the broader regulatory goals concerning transparency in consumer markets. It is argued that EU law focuses on adequate information being provided to lay consumers (exoteric transparency), rather than on understandability to experts (esoteric transparency). A discussion follows on the benefits of transparency, on its costs, and on the extent to which transparency can be implemented without affecting performance. Finally, the merits of a transparency-based regulation of algorithms are discussed and insights are provided on regulating transparency and explainability within the EU law paradigm
Algorithmic Price Discrimination and Consumer Protection. A Digital Arms Race?
No full textOnline market players are gradually gaining the capacity to adapt prices dynamically based on knowledge generated through vast amounts of data, so that, theoretically, every individual consumer can be charged the maximum price he or she is willing to pay. This has downsides for markets and society. European Union law insufficiently addresses these issues. Consumer-empowering technologies may help counter algortihmic price discruimination. We advocate for regulation to make the arms race between conumers and sellers more balanced by strengthening the digital tools available to consumer protection actors and to limit the battlefield by clarifying and refining the applica- ble rules and defining clearer categories of impermissible behaviours
The effect of plant protein-based diet supplemented with dipeptide or free amino acids on digestive tract morphology and PepT1 and PepT2 expressions in common carp (Cyprinus carpio L.)
No full textCommon carp (Cyprinus carpio) of average body mass 0.07+/-0.02 g were fed three formulated diets: wheat gluten protein-based diet supplemented with Lys-Gly dipeptide (PP), wheat gluten protein-based diet supplemented with free lysine and glycine (AA), and a wheat gluten protein-based control diet without lysine supplementation (CON), frozen zooplankton (Z) (restricted diet), and a commercial starter food Aglo Norse (AN). After 4 weeks of experimental feeding, fish fed AN diet showed the highest body mass and length. Significantly lower mass occurred in groups fed PP, AA, CON, and Z. Fish fed CON diet showed the lowest intestinal folds and the highest number of mucous cells. Fish fed PP diet showed a significantly higher number of gastrin/cholecystokinin (CCK) positive cells. The diameter of lipid vacuoles in hepatocyte cytoplasm of fish fed formulated diets (PP, AA and CON) was significantly higher than in fish fed zooplankton (Z) and the commercial diet (AN). Hepatocytes of fish fed AA and CON showed a higher nucleus proliferation rate than in the other experimental groups. The quantitative analysis of the number of proliferating cell nuclear antigen (PCNA) and caspase-3(rabbit polyclonal antibody CPP-32)-positive cells showed that the highest proliferation rate was accompanied by the high apoptosis in the intestine of fish fed AA and CON. After 4 weeks of experimental feeding the highest relative expression of PepT1 gene was observed in fish fed PP diet, while the lowest expression occurred in fish fed CON. Feeding carp plant protein-based diet supplemented with Lys-Gly dipeptide (PP) had a beneficial influence on fish growth and metabolism in the digestive tract as compared to fish fed control diet without lysine supplementation (CON)
