Observations made on the museums in Portici and on the Vesuvian sites by two Swedish professionals in 1756 and 1768, respectively

This article presents two formerly unedited travelaccounts, transcribed from the Swedish manuscripts and translated into English, narrating visits to Herculaneum, the Herculanense Museum and Pompeii, by Georg Fröman, Royal maçon, and Johan Tobias Sergel, sculptor, respectively. The texts are commented and put in historical context. Sergel's thorough accout of the Museum is read in parallel with th

Piranesi’s Grande Cheminée, virtually recreated for John Wilton-Ely

This text presents a virtual reconstruction of an exceptional chimneypiece, made during the very last days of Giovanni Battista Piranesi’s activity in the marble business. After its export to Sweden, the marble double frame (jambs and architraves) from which it was constituted were divided, and reused for two distinct chimneypieces, located in two different Royal residences. The origins of these p

Calibration of the carbon isotope composition (δ13C) of benthic foraminifera

The carbon isotope composition (δ13C) of seawater provides valuable insight on ocean circulation, air-sea exchange, the biological pump, and the global carbon cycle and is reflected by the δ13C of foraminifera tests. Here more than 1700 δ13C observations of the benthic foraminifera genus Cibicides from late Holocene sediments (δ13CCibnat) are compiled and compared with newly updated estimates of t

Metal-dielectric transition in Sn-intercalated graphene on SiC(0001)

The Sn intercalation into a buffer layer graphene grown on 4H-SiC(0001) substrate has been studied with spectroscopic photoemission and low energy electron microscope. Both SnSix and SnOx interfacial layers are found to form below the buffer layer, converting it into a quasi-free-standing monolayer graphene. Combining the various operation modes of the microscope allows a detailed insight into the

A bimetallic nanocoral Au decorated with Pt nanoflowers (bio)sensor for H2O2 detection at low potential

In this work, we have developed for the first time a method to make novel gold and platinum hybrid bimetallic nanostructures differing in shape and size. Au-Pt nanostructures were prepared by electrodeposition in two simple steps. The first step consists of the electrodeposition of nanocoral Au onto a gold substrate using hydrogen as a dynamic template in an ammonium chloride solution. After that,

Short communication : Weak associations between mastitis control measures and bulk milk somatic cell counts in Swedish dairy herds

Despite the fact that control programs have been available for several decades, mastitis remains an important problem in dairy herds around the world. Possible reasons for this include poor uptake and application of recommended mastitis control measures; poor or variable compliance; or variability in the effects of these measures. The objective of this study was to evaluate the associations betwee

Academic knowledge and economic growth : Are scientific fields all alike?

The article elaborates and tests the hypothesis that there are different types of aca demic knowledge that exert different effects on economic growth. Knowledge items differ with respect to the specificities of both their generation and exploitation pro cesses. Building upon these bases, the article articulates the crucial distinction between knowledge as a capital good, necessary to produce all t

Which cloud auto-scaler should i use for my application? Benchmarking auto-scaling algorithms : [Poster paper]

Rapid elasticity is one of the essential characteristics of cloud computing identified by NIST [17]. Elasticity allows resources to be provisioned and released to scale rapidly out ward and in ward according to demand. Tens - if not hundreds - of algorithms have been proposed in the literature to automatically achieve elastic provisioning [15, 23, 14, 21, 13, 20, 6, 12, 16, 10]. These algorithms a

Deblending seismic data by directionality penalties

In conventional seismic surveys, there is a waiting time between sequentially fired shots. This time is determined such that the deepest reflection of interest is recorded before the following source is fired. In a survey with simultaneous or blended sources, the waiting time between the firing of shots is not dependent on the deepest reflection of interest, it is usually much shorter and/or can h

Transporting Inequalities: On Transport in Urban and Regional Inequalities

Despite a surge in critical urban studies, the role of transport infrastructure and its material and virtual aspects is still underdeveloped in studies of urban and regional inequalities. Transport infrastructure involves processes of everyday mobility in and to the city, including accessibility to work, services and green areas. Moreover, transport infrastructure guides processes of urban and reg

On the diversity and richness of understory bryophytes at Nectandra Cloud Forest Reserve, Costa Rica

Background A survey of the understory bryophytes in the Nectandra Cloud Forest Preserve yielded 1083 specimens distributed among 55 families, represented by 74 genera of mosses, 75 genera of liverworts and 3 of hornworts. We studied and analyzed the bryophytic distribution on six types of substrates: 1) corticolous, 2) epiphyllous, 3) saxicolous, 4) terricolous, 5) aquatic and 6) lignicolous. The

Production of π0 and η mesons up to high transverse momentum in pp collisions at 2.76 TeV

The invariant differential cross sections for inclusive π0 and η mesons at midrapidity were measured in pp collisions at s=2.76 TeV for transverse momenta 0.4 < pT< 40 GeV/c and 0.6 < pT< 20 GeV/c, respectively, using the ALICE detector. This large range in pT was achieved by combining various analysis techniques and different triggers involving the electromagnetic calorimeter (EMCal). In particul

Azimuthally Differential Pion Femtoscopy in Pb-Pb Collisions at sNN =2.76 TeV

We present the first azimuthally differential measurements of the pion source size relative to the second harmonic event plane in Pb-Pb collisions at a center-of-mass energy per nucleon-nucleon pair of sNN=2.76 TeV. The measurements have been performed in the centrality range 0%-50% and for pion pair transverse momenta 0.2
