The acoustic emission that is detectable in the forming of complex thin part plates contains information about the quality of the pressed plates. The information can be used as process control and to filter out advanced thin plates with defects such as cracks. The article describes the results obtained in a try-out pressing process in special developed punch-die pairs with different pressing

Artikeln söker förklara varför de svenska tjänstemännen organiserade sig i egna fackförbund och centralorganisationer (Sverige har världes mest socialt segregerade fackliga rörelse genom uppdelning på särskilda fackföreningar för arbetare, akademiker och övriga tjänstemän)

Objectives: A potential role in cancer biology is suggested for YKL-40 (CHI3L1, HC gp-39). The purpose of this study was to evaluate the clinical value of serum YKL-40 (sYKL-40) in multiple myeloma (MM) and to examine YKL-40 expression in malignant plasma cells (MM PCs). Methods: sYKL-40 was measured by enzyme-linked immunosorbent assay (ELISA) in 82 patients with newly diagnosed MM. YKL-40 expres

Background: Few studies have described how neurohormonal activation is influenced by treatment with beta-receptor antagonists in patients with heart failure after acute myocardial infarction. The aims were to describe neurohormonal activity in relation to other variables and to investigate treatment effects of a beta, receptor-antagonist compared to a partial beta, receptor-agonist. Methods: Doubl

The airway resistance, compliance of the respiratory system, transfer factor, and alveolar volume of 33 healthy rabbits were studied before and after exposure to diluted diesel exhaust generated in an experimental motor. Three diesel fuels and two particle traps were tested. Subsequent to the post-exposure lung function measurements, the animals were sacrificed and the lungs were processed for mor

The aim of this study was to evaluate the changes caused by chronic diabetes in the rat ventral prostate and to establish a correlation between diabetes and the development of prostatic lesions. Male rats received alloxan (42 mg/kg b.w.) to induce diabetes. Ninety days after diabetes diagnosis, animals were sacrificed and the ventral prostate was removed and prepared for general and immunohistoche

The name 'Acinetobacter venetianus' has been used previously to designate three marine hydrocarbon-degrading Acinetobacter strains, of which strain RAG-1 (=ATCC 31012) has industrial applications for the production of the bioemulsifier emulsan. However, to date, the name of this taxon has not been validly published. In this study, five strains were examined to corroborate the delineation of this t

We studied clinical performance of serum TRACP 5b and other bone turnover markers, including S-CTX, U-DPD, S-PINP, S-BALP, and S-OC, for monitoring alendronate treatment. TRACP 5b had higher clinical sensitivity, area under the ROC curve, and signal-to-noise ratio than the other markers. INTRODUCTION: The purpose of this study was to compare the clinical performance of serum TRACP 5b (S-TRACP5b) w

Lipoprotein-associated phospholipase A2 (Lp-PLA2) is today considered a novel specific vascular inflammatory biomarker. The general aim of this thesis was to study the role and impact of Lp-PLA2 as cardiovascular (CV) risk marker in an epidemiologic perspective. Specific aims were to explore the cross-sectional association of Lp-PLA2 with traditional CV risk factors, to asses the genetic influence

The Medipix detector is the first device dedicated to measuring mixed-field radiation in the CMS (Compact Muon Solenoid) experiment cavern and able to distinguish between different particle types. Medipix2-MXR chips bump bonded to silicon sensors with various neutron conversion layers developed by the IEAP CTU in Prague were successfully installed for the 2008 LHC start-up in the CMS experimental

Aim. The aim of this paper was to evaluate short-term outcome of the use of endoanchors to secure the primary migrated endograft and additional extender cuffs to the aortic wall in patients with previous failed endovascular aortic aneurysm repair. Methods. Consecutive patients who needed proximal repair of a primary failed endograft due to migration (with or without type IA endoleaks) were treated

Popular Abstract in Swedish En amfifil molekyl har två delar; en del som dras till olja och en del som dras till vatten. Dessa två delar benämns vanligen huvudgrupp respektive svans. Amfifila molekyler kallas ofta tensider (på engelska surfactants), och är de aktiva beståndsdelarna i bland annat tvättmedel och hårschampo. Amfifila molekyler i vattenlösning formar sig så att vattendelarna dras tillThe formation of highly ordered mesoporous silica materials, using PEO-PPO-PEO amphiphilic triblock copolymers (so-called Pluronics) as structure directing agents, has been studied. The materials are formed through the addition of a silica source to a polymer solution of low concentration (2.5 wt ) under acidic conditions. The products have BET surface areas of approximately 800 m2/g. The unit cel

One significant environmental impact from assembly operations includes packaging material use and subsequent waste generation. Although current practice involves reduction of unnecessary materials handling, there is potential to adapt packaging material in order to simultaneously improve the environmental performance and reduce cost in a “lean and green” mindset. Hence, with increased emphasis on

The aim of this work was to investigate and quantify the effects of system noise, nodule location, anatomical noise and anatomical background on the detection of lung nodules in different regions of the chest x-ray. Simulated lung nodules of diameter 10 mm but with varying detail contrast were randomly positioned in four different kinds of images: 1) clinical images collected with a 200 speed CR s

This paper attempts to address the failings of a predominant paradigm in IS research and practice that emphasises technological determinism. This paradigm makes use of a false belief in the power of rationality in organizational decision-making, and a mythology in which organizational actors can be viewed as passive ‘users’ of technology. We wish to create a discussion of the nature and role of pr

The paper reviews a number of cellular neural network implementations on a field-programmable gate-array. It illustrates experimentally, how these implementations can be used to measure from images or to create dynamic, autonomous processes that facilitate measurements within topographic maps. Applications range from image understanding to robot navigation

Mycobacterium tuberculosis (Mtb) employs various strategies to modulate host immune responses to facilitate its persistence in macrophages. The Mtb cell wall contains numerous glycoproteins with unknown role in pathogenesis. Here, by using concavalinA and LC-MS analysis we identified a novel mannosylated glycoprotein phosphoribosyl- transferase, encoded by the Rv3242c, from Mtb cell walls. Homolog

A high energy supply and appropriate amount of polyunsaturated fatty acids is crucial for proper growth and development in neonates. The capacity for fatty acid absorption in newborns is however hampered due to an undeveloped pancreatic function combined with a low bile output. This seems in particular to limit fatty acid absorption in babies given infant formulas. Since interaction between the li
