This study explores the meaning of the two expressions 'times of refreshing' and 'time to restore everything' in Acts 3:19.21. These two eschatological motifs appear in a speech that the apostle Peter made, according to Luke's presentation, in the Jerusalem temple in the beginning of the 30s. The study is historical, and the meaning of the two expressions is sought in the contemporary world. It i
Experiments on dry face turning offunctionallygraded heat treatable steel are conducted. The workpieces have a hardened zone of approx. 60 HRC and a non-hardened zone of approx. 30 HRC. PCBN tools are used with different feeds, cutting speeds and depths of cut. Measurements of residual stresses in the surface layer reveal compressive stresses in the hardened zone and tensile stresses in the non-ha
We have previously shown synovial fluid (SF) proteoglycan concentrations to be sensitive markers of altered cartilage metabolism in arthritis. We determined the proteoglycan concentrations in sera and SF from 23 patients with juvenile chronic arthritis and in sera from 30 healthy children by a specific enzyme linked immunosorbent assay. In both groups of children, decreasing concentrations of prot

An algorithm specific digital signal processor is a powerful alternative to a general purpose signal processor for demanding specifications such as high throughput, low power, small size, etc. These properties are achieved as the processor architecture is tailored to the algorithm as opposed to the general purpose architecture which must suit a wide range of algorithms. The increased performance i
HD 129590 is a stellar system with a directly imaged debris disk located in the Scorpius–Centaurus association, approximately 420 light years away. With an estimated age of 15 Myr, young systems like HD 129590 have been ideal for studying the development and evolution of exocomets and planetary disks at early epochs of star formation, at a time when such structures are just emerging. Consequently,

Abstract Title: A holistic study of the factors influencing the co-creation process in the B2B market from two perspectives v Date of the seminar: 25.05.2016 Course: ENTN39 Master‘s Corporate Entrepreneurship and Innovation Internship and degree project (Master‘s thesis 15 ECTS) Supervisor: Joakim Winborg Research questions: What factors influence the co-creation process in a B2B context from
Esters of phosphoric acid constitute a sizable fraction of the total phosphorus supply in the environment and thus play an important role in the global phosphorus cycle. Enzymatic hydrolysis of these esters to produce orthophosphate is often a required reaction preceding phosphorus uptake by plants and microorganisms. Generally, adsorption to environmental particles is assumed to limit this proces
Heading towards a full automation of next-to-leading order (NLO) QCD corrections, one important ingredient is the analytical integration over the one-particle phase space of the unresolved particle that is necessary when adding the subtraction terms to the virtual corrections. We present the implementation of these integrated dipoles in the MadGraph framework. The result is a package that allows a
The current study demonstrates through experiment the effect of solid lubricant assisted minimum quantity lubrication (MQL) on the machining performance when turning Alloy 718 with cemented carbide tools. A powder of nanosized (~30 nm) graphite nanoplatelets (GnP) was dispersed (0.2% vol.) in a vegetable oil-based lubricant “ECOLUBRIC E200L” and used in MQL-assisted machining. The effect of cuttin
This work provides new insights into the presence of 239Pu, 240Pu, 241Pu, and 236U in the Southern Hemisphere through the study of peat bog cores from marshlands in Madagascar (19°S). 210Pb, 238Pu and 239+240Pu activities were characterized by alpha spectrometry in previous studies. Here, Pu from alpha-spectrometry discs corresponding to 10 peat-bog cores (85 samples) was reassessed for the aim of
We report a new design of an acoustophoretic trapping device with greatly increased capacity and throughput, compared to current commercial systems. Acoustic trapping enables nanoparticle and exosome enrichment without the need for ultracentrifugation. The commercial acoustic trapping technology, AcouTrap (AcouSort AB), typically operates at flow rates < 50 μl/min which limits processing of larger
We report magnetic properties and relative paleointensity (RPI) proxies from a suite of 10 conventional piston cores and Kasten cores from the SW Iberian Margin collected during cruise JC089 of the RSS James Cook in August 2013. Mean sedimentation rates are in the 10–20 cm/kyr range. Age models were acquired by correlation of Ca/Ti and Zr/Sr XRF core-scanning data to L* reflectance from the Cariac
A system consisting of a high-pressure tolerant microfluidic glass chip, high-speed absorbance imaging, and image processing has been developed to study rapid dynamic events like pH change in a multiphase flow. The system gives both kinetic and quantitative equilibrated information. By tracking the interactions of aqueous additive mixtures and liquid CO2, at 80 bar and 24 °C, under flow, measureme
QmeQ is an open-source Python package for numerical modeling of transport through quantum dot devices with strong electron-electron interactions using various approximate master equation approaches. The package provides a framework for calculating stationary particle or energy currents driven by differences in chemical potentials or temperatures between the leads which are tunnel coupled to the qu
