Module Development for the Phase-2 ATLAS ITk Pixel Upgrade
No full textFor the high luminosity era of the Large Hadron Collider (HL-LHC) it is foreseen to replace the current inner tracker of the ATLAS experiment with a new, all-silicon detector to cope with the occurring increase in occupancy, bandwidth and radiation damage. It will consist of an inner pixel and outer strip detector aiming to provide tracking coverage up to |η|=4. The layout of the pixel detector is foreseen to have five layers of pixel silicon sensor modules in the central region and several ring-shaped layers in the forward region. This results in up to 14 m² of silicon depending on the selected layout. Detector requirements in terms of radiation hardness and occupancy, as well as thermal performance depend strongly on the distance from the interaction region. Therefore, the innermost layer will feature 3D silicon sensors, due to their inherent radiation hardness and low power consumption, while the remaining layers will employ planar silicon sensors with thickness ranging from 100µm to 150µm. All hybrid detector modules will be read out by novel ASICs, implemented in 65nm CMOS technology and thinned to 150µm, which will be connected to the silicon sensors using bump bonding. With about 4 104 pixels per cm² the bump bond density is a much higher than in previous hybrid detectors. With the recent availability of the first prototype readout chip, the RD53A, module development for the ITk Pixel Detector is entering a new phase. Numerous modules will be assembled to test the performance of bump bonding of objects of realistic area, very small thickness and high bump bond density, as well as to finalize studies of the module performance with pixel pitches of 50x50µm² and 25x100µm² on the sensors. The stack-up of these hybrid pixel modules can be seen in Fig. 1. Flex circuits are glued on top of the modules for connection and routing of services which have to be qualified too. Moreover, tests of the new serial powering scheme for low voltage supply of the modules will be done as part of the prototyping program. The quality assurance criteria for the production of the final detector modules are verified, including mechanical properties like module flatness as well as electrical tests of the functionality of the modules and the bump bond quality. We will present the latest results from the assembly and characterization of the prototype modules. Important qualification steps of the module design will be discussed

POLA KALIMAT PADA KUMPULAN DONGENG GADIS KOREK API KARYA H.C. ANDERSEN (SUATU KAJIAN SINTAKSIS)
No full textThis study described syntactic structure on fairy-tale collection of Gadis Korek Api by H.C. Andersen. The study which seen from syntactic structure is sentence pattern based on function category, category, and syntactic role. This study aimed to describe syntactic structure on fairy-tale collection of Gadis Korek Api by H.C. Andersen and it’s distribution towardh Indonesian language. This research used qualitative method and note method was employed for collecting the data. In analysing the data, the researcher used Agih method by applying Immediate Constituent Analysis technique (ICA) as a basic technique. A book entitled Gadis Korek Api and others fairy-tale are the work of danish author, H.C. Andersen that used Indonesian standard. The analysis showed syntactic structure of fairy-tale language which form of sentence pattern based on the user, the pattern of imperative sentence, sentence pattern contains conjunction, and sentence pattern of complex sentences. Keywords: Sentence Pattern; Fairy-tale; Syntactic.</p

General H.C. Pratt, Commanding General of Western Defense Command, statement on releasing incarcerees
No full textStatement by General H.C. Pratt, Commanding General of the Western Defense Command about releasing incarcerees from camps and it being under his jurisdiction rather than the WRA's. Pratt states that he has the intelligence records from the various agencies and is equipped to make the decisions on safely releasing incarcerees.The War Relocation Authority (WRA), together with the Wartime Civil Control Administration (WCCA), the Civil Affairs Division (CAD) and the Office of the Commanding General (OFG) of the Western Defense Command (WDC) operated together to segregate and house some 110,000 men women and children from 1942 to 1945. The collection contains documents and photographs relating to the establishment and administrative workings of the (WDC), the (WRA) and the (WCCA) for the year 1942
Induced surface proteins of Streptococcus epidermidis adhering to titanium implant substrata
No full textStaphylococcus epidermidis, as a primary colonizer, is strongly associated with infections of (dental) implants (i.e., peri-implantitis), but little is known about the surface proteome of this bacterium. For the identification of bacterial adhesins, this study investigated the surface proteome of S. epidermidis adhering directly to titanium implant substrata. S. epidermidis strain ATTC 35984 was cultured either planktonically or on titanium implant specimens. The surface proteomes were isolated by mutanolysin digestion, and proteins were separated by 2D gel electrophoreses to reveal highly expressed proteins only. Protein spots were visualized by silver staining and proteins were identified by mass spectrometry. Surface proteome analyses of S. epidermidis on titanium identified six expressed proteins. Three proteins were highly expressed on the titanium implants including accumulation-associated protein Q8CQD9. These specific proteins could be potential pathogenicity factors of bacteria in peri-implant biofilms. For the first time, our study identified S. epidermidis surface proteins, which are expressed after adhesion to titanium implant materials. Our study reveals possible candidates for a newly protein-based vaccine against peri-implantitis

Light-promoted synthesis of highly-conjugated crystalline covalent organic framework
No full textLow electrical conductivity caused by low degree of π-conjugation and structural disorders induces critical limitations in electronic applications of covalent organic frameworks (COFs). Here we focus on improving the electrical properties of COFs by synthesis of highly conjugated and crystalline COF (hcc-COF). Addition of a small amount of water and acetic acid induces the efficient reversible dynamic imine condensation reaction that is required to obtain uniform and crystalline products. Also, simulated sunlight irradiation facilitates the reversible imine condensation reaction, and achieves formation of hcc-COF with high-yield within short reaction time. The obtained hcc-COF has an extended π-conjugated structure along the lateral direction and an inclined stacking structure. The intrinsic electron transport properties along the in-plane direction are evaluated using a hcc-COF film grown on a water surface from a polarity-controlled precursor solution. To the best of our knowledge, our hcc-COF film shows the highest reported electrical conductivity for highly conjugated organic porous polymers. © 2019, The Author(s).11Ysciescopu
H.C. Andersens København - Når Kina møder Danmark
No full textWe have made a prototype of an application for Chinese tourists in the city of Copenhagen. A marked research by Chinavia, a pilot project for Wonderful Copenhagen, pointed that there is an opening in the Scandinavian marked regarding tourist information in Chinese. Furthermore the research showed that 82 pct. of the Chinese tourists in Scandinavia uses their smartphones during travels. The Danish author Hans Christian Andersen is a great brand in China and therefor we saw this as an opportunity for making an application for Chinese tourist in Copenhagen witch conveys the fairytales of Andersen in Chinese while experiencing the city. During the development of the application we have used a variety of theories and methods, including: Design Thinking, the theory of Affordance, Usability Testing, Explanatory Design Theory. C.R.A.P design, Data Flow Diagram, Context Diagram and the Gestalt principles.We have made a prototype of an application for Chinese tourists in the city of Copenhagen.
