The archaeological site of Heraqla in Raqqa represents a particular example of the Abbasid architecture; the Caliph Harun Al Rashid started reconstructing it as a commemorative monument but after his death it was never completed. The Directorate General of Antiquities and Museums DGAM excavated in the site, constructed furnace to produce bricks similar to the ancient material for restorations and,
The role of mutations have been subject to many controversies since the formation of the Modern Synthesis of evolution in the early 1940ties. Geneticists in the early half of the twentieth century tended to view mutations as a limiting factor in evolutionary change. In contrast, natural selection was largely viewed as a “sieve” whose main role was to sort out the unfit but which could not create a
Mitochondria are central organelles in the homeostasis of the cardiovascular system via the integration of several physiological processes, such as ATP generation via oxidative phosphorylation, synthesis/exchange of metabolites, calcium sequestration, reactive oxygen species (ROS) production/buffering and control of cellular survival/death. Mitochondrial impairment has been widely recognized as a
The technological evolution and widespread availability of wearables and handheld ECG devices capable of screening for atrial fibrillation (AF), and their promotion directly to consumers, has focused attention of health care professionals and patient organizations on consumer-led AF screening. In this Frontiers review, members of the AF-SCREEN International Collaboration provide a critical apprais
Despite various criticisms, Ian Barbour's fourfold classification of the possible relationships between religion and science remains influential. I compare Barbour's taxonomy with the theories of four authors who, in the last four decades, have addressed the relationship between science and religion from a Muslim perspective. The aim of my analysis is twofold. First, I offer a comparative perspect
How the Internet spawns community and gets its features into offline life is a recurring problem met in searches for “impacts” of its successive iterations in the Middle East and arises particularly in assessing equivocal findings most recently about social media in the Arab Spring uprisings. But the problem is more methodological than ontological: it lies in viewing the Internet through a media l
Features below the first conductance plateau in ballistic quantum point contacts (QPCs) are often ascribed to electron interaction and spin effects within the single mode limit. In QPCs with a highly asymmetric geometry, we observe sharp resonance peaks when the point contacts are gated to the single mode regime, and surprisingly, under certain gating conditions, a complete destruction of the 2e(2
We report on a setup for the investigation of proton acceleration in the regime of target normal sheath acceleration. The main interest here is to focus on stable laser beam parameters as well as a reliable target setup and diagnostics in order to do extensive and systematic studies on the acceleration mechanism. A motorized target alignment system in combination with large target mounts allows fo
Chronic myeloid leukemia (CML) is characterized by a specific chromosome translocation, and its pathobiology is considered comparatively well understood. Thus, quantitative analysis of CML and its progression to blast crisis may help elucidate general mechanisms of carcinogenesis and cancer progression. Hitherto, it has been widely postulated that CML blast crisis originates mainly via cell-autono
This article examines what image of Russia is being projected in official rhetoric about the Sochi Olympics. It is argued that the imagined community being displayed is a diverse, inclusive and tolerant nation, even an international example of ethnic conviviality. The article puts this narrative in historical perspective, relating it to the mnogonatsionalnost policies of tsarist, Soviet and post-S
Popular Abstract in Swedish Wnt-5a-genens betydelse för bröstcellernas normala funktion och för uppkomsten av bröstcancer I min avhandling har jag studerat en i bröstcancersammanhang hittills föga undersökt gen, Wnt-5a. Benämningen Wnt har bildats genom en sammanslagning av "Wingless" (den första identifierade Wnt-genen som orsakar vinglöshet hos bananflugan) och "Int" (från "Integration site" föThe Wnt-5a gene encodes a secreted protein that regulates several normal processes in embryonic and adult tissues by as yet unknown mechanisms. Expression of Wnt-5a protein does not cause cell transformation, but it instead counteracts the effects induced by transforming Wnts. Inasmuch as Wnt-5a can activate the Wnt/beta-catenin signalling pathway, we performed experiments to determine whether mol
The ability to understand packaging and how it contributes to the establishment of efficient logistics and the creation of individualised values for consumers is becoming increasingly important. This licentiate thesis stresses the importance of applying a holistic view of packaging in order to be able to understand how to adapt the distribution channel to meet consumer demands. The study focuses o
Critical infrastructures provide society with services that are essential for its functioning and extensive disruptions of these give rise to large societal consequences. Vulnerability analysis gives important decision information concerning improving their ability to withstand strains. To analyze vulnerabilities in infrastructures models for estimating consequences due to failures are needed. Con
