Midlatitude shelf seas in the Cenomanian‐Turonian greenhouse world: Temperature evolution and North Atlantic circulation

Abstract: [1] An 8 million year record of subtropical and midlatitude shelf-sea temperatures, derived from oxygen isotopes of well-preserved brachiopods from a variety of European sections, demonstrates a long-term Cenomanian temperature rise (16–20°C, midlatitudes) that reached its maximum early in the late Turonian (23°C, midlatitudes). Superimposed on the long-term trend, shelf-sea temperatures vary at shorter timescales in relation to global carbon cycle perturbations. In the mid-Cenomanian and the late Turonian, two minor shelf-sea cooling events (2–3°C) coincide with carbon cycle perturbations and times of high-amplitude sea level falls. Although this evidence supports the hypothesis of potential glacioeustatic effects on Cretaceous sea level, the occurrence of minimum shelf-sea temperatures within transgressive beds argues for regional changes in shelf-sea circulation as the most plausible mechanism. The major carbon cycle event in the latest Cenomanian (oceanic anoxic event 2) is accompanied by a substantial increase in shelf-sea temperatures (4–5°C) that occurred ∼150 kyr after the commencement of the δ13C excursion and is related to the spread of oceanic conditions in western European shelf-sea basins. Our oxygen isotope record and published δ18O data of pristinely preserved foraminifera allow the consideration of North Atlantic surface water properties in the Cenomanian along a transect from the tropics to the midlatitudes. On the basis of fossil-derived δ18O, estimated δw ranges, and modeled salinities, temperature-salinity-density ranges were estimated for tropical, subtropical, and midlatitude surface waters. Accordingly, the Cenomanian temperate shelf-seas waters have potentially the highest surface water density and could have contributed to North Atlantic intermediate to deep waters in the preopening stage of the equatorial Atlantic gateway.

Curcumin and Liver Disease: from Chemistry to Medicine

Abstract: Curcumin, the natural yellow-colored active principle, also called turmeric yellow, extracted from the perennial herb Curcuma longa L., has potent biological and pharmacological properties such as antioxidant, anti-inflammatory, antifungal, antibacterial, anti-ischemic, antitumor, and anticancer actions. The molecular mechanism of the hepatoprotective action of curcumin is due to its antioxidant properties and inhibitory activity against nuclear factor (NF)-κB that regulates different proinflammatory and profibrotic cytokines. Overall, scientific reports demonstrate that curcumin has high therapeutic ability for treating hepatic disorders. Here is a systematic discussion of the hepatoprotective activity of curcumin and its possible mechanisms of actions.

Learning Programming at the Computational Thinking Level via Digital Game-Play

Abstract: This paper outlines an innovative game model for learning computational thinking (CT) skills through digital game-play. We have designed a game framework where students can practice and develop their skills in CT with little or no programming knowledge. We analyze how this game supports various CT concepts and how these concepts can be mapped to programming constructs to facilitate learning introductory computer programming. Moreover, we discuss the potential benefits of our approach as a support tool to foster student motivation and abilities in problem solving. As initial evaluation, we provide some analysis of feedback from a survey response group of 25 students who have played our game as a voluntary exercise. Structured empirical evaluation will follow, and the plan for that is briefly described.

Islamic marketing – a challenger to the classical marketing canon?

Abstract: Purpose – The purpose of this paper is to debate what (if anything) is Islamic marketing? And link developments in this field to the wider marketing paradigm.Design/methodology/approach – A phenomenological antipositivist review of key case examples, drawing from 40 years of the authors' collective professional experiences; and field notes investigating approximately 1,000 brand marketing media reports, and 32 in‐depth interviews – as industry active academic practitioners. Supporting this, literature searches covered the fields of marketing, cultural studies, anthropology, contemporary religion, post‐structuralism and natural philosophy.Findings – Marketing is both a concept and lived experience, manifest in the competitive exchange of commoditised thoughts, feelings, actions and objects – between engaged individuals and collectives. For many reasons, Islamic and Brand agendas/imperatives have risen in the consciousness and practises of Muslims and non‐Muslims globally, through social interactions. These...
