Purpose - With the help of Slavoj Zizek's concept of interpassivity, this paper seeks to illustrate the frantic activities performed by employees to maintain a separation between the idea of an authentic self and the idea of a corporate self. Furthermore, this paper aims to illustrate these activities empirically. Design/methodology/approach - The empirical example is based on a case study of thre

The motivation for using a zero-dispersion monochromator as a band-pass filter with a Fourier transform spectrometer is discussed, and the design of such an instrument is presented. Benefits in performance over commercial band-pass filters are demonstrated. In addition the advantages of using the second optical output of the spectrometer are discussed, particularly with respect to absorption spect

We report on the production and characterization of polymer-based ultra-thin (sub 10 nm) foils suited for experiments on laser-ion acceleration in the regime of radiation pressure acceleration. Beside the remarkable mechanical stability compared with commonly used diamond-like-carbon foils, a very homogeneous layer thickness and a small surface roughness have been achieved. We describe the technic

Currently, the habitat of many species is fragmented, resulting in small local populations with individuals occasionally dispersing between the remaining habitat patches. In a solitary bee metapopulation, extinction probability was related to both local bee population sizes and pollen resources measured as host plant population size. Patch size, on the other hand, had no additional predictive powe

OBJECTIVES: To gain an improved understanding of fatigue in Parkinson's disease (PD) by exploring possible predictors among a wide range of motor and non-motor aspects of PD. METHODS: 118 consecutive PD patients (54% men; mean age, 64 years) were assessed regarding fatigue, demographics and a range of non-motor and motor symptoms. Variables significantly associated with fatigue scores in bivariate

Background and purpose Although decreasing with the development of effective pharmacological regimes, joint surgery has improved the function and quality of life of patients with rheumatoid arthritis (RA). Few studies have assessed patient-reported outcomes after RA surgery to the lower extremities. Here we report patient-relevant outcome after RA-related surgery based on the first data from the S

We report on growth and characterization of wurtzite InP-In1-xGaxAs core-shell nanowire heterostructures. A range of nanowire structures with different Ga concentration in the shell was characterized with transmission electron microscopy and X-ray diffraction. We found that the main part of the nanowires has a pure wurtzite crystal structure, with occasional stacking faults occurring only at the t

Purpose: In a prospective study, we assessed if a diagnosis of osteoporosis and periodontitis could predict hip and hand fractures in older persons. Materials and methods: Bone density was assessed by a Densitometer. Periodontitis was defined by evidence of alveolar bone loss. Results: 788 Caucasians (52.4% women, overall mean age: 76 years, S.D. +/- 9.0, range: 62 to 96) were enrolled and 7.4% ha

We studied the microbial communities in maize (Zea mays) rhizosphere to determine the extent to which their structure, biomass, activity and growth were influenced by plant genotype (su1 and sh2 genes) and the addition of standard and high doses of different types of fertilizer (inorganic, raw manure and vermicompost). For this purpose, we sampled the rhizosphere of maize plants at harvest, and an

Single photons detected by the DELPHI experiment at LEP2 in the years 1997-2000 are reanalysed to investigate the existence of a single extra dimension in a modified ADD scenario with slightly warped large extra dimensions. The data collected at centre-of-mass energies between 180 and 209 GeV for an integrated luminosity of similar to 650 pb(-1) agree with the predictions of the Standard Model and

We study the effects of a phase difference on Yu-Shiba-Rusinov (YSR) states in a spinful Coulomb-blockaded quantum dot contacted by a superconducting loop. In the limit where charging energy is larger than the superconducting gap, we determine the subgap excitation spectrum, the corresponding supercurrent, and the differential conductance as measured by a normal-metal tunnel probe. In absence of a

Childhood Acute Lymphoblastic Leukaemia (ALL) has a unique place in the history of oncology, as it was the first cancer to be cured by drugs. It is therefore an important model upon which concepts of chemotherapy in other malignancies have been developed. Methotrexate is a major component of most contemporary childhood ALL treatment protocols. The main objectives of this thesis were to investigat

In the presence of excess hydrogen peroxide (H2O2), ferrous (Fe(+2)) human hemoglobin (Hb) (α2β2) undergoes a rapid conversion to a higher oxidation ferryl state (Fe(+4)) which rapidly autoreduces back to the ferric form (Fe(+3)) as H2O2 is consumed in the reaction. In the presence of additional H2O2 the ferric state can form both ferryl Hb and an associated protein radical in a pseudoperoxidative

The increasing size of the population results in that unbuilt spaces needing to be used for the construction of new facilities. Large construction sites can generate disturbing vibrations to nearby buildings, both while construction is underway and afterwards through the operation of subways, for example. The establishment of new areas close to, for example, motorways and railways increases the ri

Homogeneous Charge Compression Ignition (HCCI) is a promising internal combustion engine concept. It holds promise of combining low emission levels with high efficiency. However, as ignition timing in HCCI operation lacks direct actuation and is highly sensitive to operating conditions and disturbances, robust closed-loop control is necessary. To facilitate control design and allow for porting of

The work presented here is based on two papers, both pertaining to perturbation-based control strategies in industrial fed-batch fermentation processes. The first paper describes a new control strategy for avoiding overflow metabolism in the exponential growth phase of a fermentation, based on analysis of the frequency spectrum of the dissolved oxygen measurement following a periodic perturbation

Popular Abstract in Swedish Varje år insjuknar omkring 300 barn i cancer. Förbättrade behandlingsmetoder under de senaste decennierna har lett till att mer än tre av fyra barn idag faktiskt botas från sin sjukdom. Tyvärr drabbas en stor andel av de som överlever sin cancer av så kallade sena komplikationer till följd av den tuffa behandling de har utsatts för. Bland annat har man sett en livslång The etiology of childhood cancer is largely unknown. Approximately 1-10% of all childhood tumors are associated with known cancer predisposition syndromes. However, the contribution may be underestimated due to the failure to detect patients with genetic susceptibility for cancer when relying on known family pattern and anomalies. Growing evidence indicates that patients with genetic susceptibilit
