In precision hard turning, tool flank wear is one of the major factors contributing to the geometric error and thermal damage in a machined workpiece. Tool wear not only directly reduces the part geometry accuracy but also increases the cutting forces drastically. The change in cutting forces causes instability in the tool motion, and in turn, more inaccuracy. There are demands for reliably monito
We report extensive relativistic multiconfiguration Dirac-Hartree-Fock calculations of oscillator strengths and hyperfine structures for a large number of electric dipole transitions in In II. Results for the 5s(21)S(0)-5s5p P-3(0)o hyperfine induced transition are also presented. Core polarization is accounted for by means of explicit CI. To describe spin-polarization effects configuration state
Abstract Purpose – The purpose of this paper is to examine the way organizational actors argue to obtain a license to operate for new ventures. Design/methodology/approach – The design, which addresses the issue at the industry level, consists of a case study of the ways in which power developers argue for the development of wind energy in Sweden. Findings – The study shows that wind power develop
Stopped-flow kinetics showed that the inhibition of the lysosomal cysteine proteinase, cathepsin B, by its endogenous inhibitor, cystatin C, occurs by a two-step mechanism, in which an initial, weak interaction is followed by a conformational change. The initial interaction most likely involves binding of the N-terminal region of the inhibitor to the proteinase. Considerable evidence indicates tha
Has the 'Swedish model' forced Sweden into stagnating economic growth? And has this caused Sweden to lag behind other comparable OECD-countries from the 1970s and onwards, i.e. since Sweden chose a welfare path different from many other countries? This has been the subject of a more than twenty year long controversy between Walter Korpi, professor of sociology and social policy, and leading Swedis
The physical phenomenon of what is now called p-n-luminescence has been known for more than 100 years. However, the effect as such was not understood until 1951 after the invention of the p-n-junction in 1947. The paper presents a brief survey of the development of LEDs in the visible region up to the early 1960s by not only focusing on the history of LEDs but also taking into account material sci
Resonant states can have an important influence on the electronic transport, noise and optical properties of heterostructure devices. We have used a non-variational method to study the resonant states formed by shallow donors inside and outside of quantum wells. The method allows us the evaluation of the position and the width (lifetime) of the resonant states and also of matrix elements such as o
New continental, national, provincial and state records of 34 species of Ptiliidae reported from North America are briefly listed, 20 of which belong to Acrotrichis Motschulsky. Eight European/Palaearctic species (Oligella foveolata (Allibert), Ptiliolum fuscum (Erichson), Ptiliola kunzei (Heer), Ptinella aptera (Guerin-Meneville), P. britannica Matthews, P. Johnsoni Rutanen, Acrotrichis parva Ros
Psoriasis is a frequently occurring inflammatory skin disease characterized by thickened erythematous skin that is covered with silvery scales. It is a complex genetic disease with both heritable and environmental factors contributing to onset and severity. The CD18 hypomorphic PL/J mouse reveals reduced expression of the common chain of beta(2) integrins (CD11/CD18) and spontaneously develops a s
We present photon correlation measurements performed on single self-assembled InP quantum dots in a GaInP barrier. Correlation measurements done under continuous excitation reveal a pronounced antibunching dip for the emission from the single exciton, the bi-exciton, and the tri-exciton. Cross-correlations between the different emission lines are used for line identification. We have correlated th
Agile methods emerged from small, contract-driven projects. This study describes lessons learned from integrating agile methods with traditional stage-gate project management models at three large, product-driven companies. The study results support the feasibility of combining these approaches and suggests some adjustments to ease the integration.
In this paper, we investigate the finite-sample distribution of the recursively mean-adjusted panel data unit root test of Shin et al. [Shin, D. W., Kang, S. and Oh, M.-S., 2004, Recursive mean adjustment for panel unit root tests. Economics Letters, 84, 433-439.]. More precisely, we provide response surface parameters that can be used to calculate small-sample critical values for the test. Furthe
OBJECTIVE: To investigate the function and morphology of endothelial cell (EC) seeded grafts. DESIGN: Experimental, open study. CHIEF OUTCOME MEASURES: Endoluminal release of prostacyclin (6-Keto-PGF1 alpha) and thromboxane B2 (TxB2), patency, EC coverage and cell identity. MATERIALS: In 12 sheep, segments of both carotid arteries were excised. On one side a seeded and on the other an unseeded dac
The violaxanthin de-epoxidase (VDE) gene from spinach (Spinacia oleracea) was cloned, sequenced (GenBank AJ 250433), and expressed in Escherichia coli. The highest obtained conversion rate of violaxanthin was 86 nmol s-1 per litre of growth medium, corresponding to an amount of active enzyme of 0.4 mg l-1. Sequence comparison between VDE from different species were made and particular interest was
Excited states of Cd-103 were studied in the reaction Ni-58(Cr-50,4pn)Cd-103. The NORDBALL array with neutron and charged particle detectors was employed for the detection of gamma rays and light evaporated particles. The level scheme of Cd-103 was significantly extended. A strong cascade of E2 transitions connecting negative parity states was found, Shell model calculations were performed and pos
