Developing TQEM in SMEs : Management Systems Approach

Small and medium sized enterprises (SMEs) play an important role in all economies today and although their individual environmental impact is often limited, their total impact can be said to be significant due to their sheer number. Environmental management is a way to reduce the impact, but the results obtained by implementing ISO 14001 vary. The point of departure for this dissertation is the hy

Narcissus's new mirror: Body images and meaning

The wish to see beyond the horizon of the human biological eye is one of the major driving forces in the development of medical imaging technology. This essay discusses the implications technology has on the ability to see, and consequently know, more about the body. Further, the potential of merging art, rehabilitation engineering and medicine to develop and use images specifically designed to cr

Detecting and correcting capabilities of convolutional codes

A convolutional code can be used to detect or correct infinite sequences of errors or to correct infinite sequences of erasures. First, erasure correction is shown to be related to error detection, as well as error detection to error correction. Next, the active burst distance is exploited, and various bounds on erasure correction, error detection, and error correction are obtained for convolution

Automatic segmentation of myocardium at risk from contrast enhanced SSFP CMR: validation against expert readers and SPECT.

Efficacy of reperfusion therapy can be assessed as myocardial salvage index (MSI) by determining the size of myocardium at risk (MaR) and myocardial infarction (MI), (MSI = 1-MI/MaR). Cardiovascular magnetic resonance (CMR) can be used to assess MI by late gadolinium enhancement (LGE) and MaR by either T2-weighted imaging or contrast enhanced SSFP (CE-SSFP). Automatic segmentation algorithms have

Human IgG/FcgammaR Interactions Are Modulated by Streptococcal IgG Glycan Hydrolysis.

BACKGROUND: The human pathogen Streptococcus pyogenes produces an endoglycosidase, EndoS that hydrolyzes the chitobiose core of the asparagine-linked glycan on the heavy chain of human IgG. IgG-binding to Fc gamma receptors (FcgammaR) on leukocytes triggers effector functions including phagocytosis, oxidative burst and the release of inflammatory mediators. The interactions between FcgammaR and th

Mental health first aid for the elderly: A pilot study of a training program adapted for helping elderly people.

Epidemiological studies have shown a high prevalence of mental illness among the elderly. Clinical data however indicate both insufficient detection and treatment of illnesses. Suggested barriers to treatment include conceptions that mental health symptoms belong to normal aging and lack of competence among staff in elderly care in detecting mental illness. A Mental Health First Aid (MHFA) trainin

Uplink power-based admission control in multi-cell WCDMA networks with heterogeneous traffic

Wideband code division multiple access (WCDMA) is an interference-limited system. When the system operates at nearly full capacity, admitting another user may affect the stability of the system. Therefore, proper Call Admission Control (CAC) is crucial and should balance between Quality of Service (QoS) requirements for the new user and also for the existing users and at the same time keep the acc

Om Queerfeministisk politik

This article discusses queer feminist politics in relation to leftist politics, and argues against the neoliberal co-optation of radical leftist political notions.

How speakers of different languages extend their turns : Word-linking and glottalisation in French and German

A speaker who issues a confirming turn starting with particles like yes, oui, ja, and so on, may mean to extend it and provide further material. This study shows that French and German speakers employ the same phonetic contrast to indicate the nature of that turn continuation. In spite of the typological difference between the German use of glottalization and the French use of linking phenomena fo

Transfer Function Parameter Identification by Modified Relay Feedback

This paper proposes a transfer function parameter identification method, applicable to SISO systems of any order. Parameter identification is posed as a (non-convex) squared output error minimization problem, numerically solved utilizing Newton-Raphson iteration with back tracking line search. Focus lies on computing the cost function gradient and Hessian with respect to the parameter vector and o

Kontrollen av brandskydd har allvarliga brister

Slutsatserna från en nyligen avslutad studie av ett fyrtiotal brandskyddsdokumentationer är oroväckande. Studien visar på allvarliga brister när det ska visas – verifieras – att samhällets krav på brandsäkerhet uppfyllts. Bristerna har inte heller uppmärksammats vid kontroll av brandskyddsdokumentationerna, vilket är både anmärkningsvärt och oroväckande.

Fast CMOS nonbinary divider and counter

A new kind of nonbinary CMOS divider and counter is presented. The divider directly gives a nonbinary dividing ratio without any decoder and, therefore, no speed degradation. They can be directly cascaded to form a nonbinary ripple chain and can be programmable. The principle is particularly useful for a nonbinary prescaler. A synchronous nonbinary counter using this principle is also presented. S

Laparoscopic extraperitoneal inguinal hernia repair versus open mesh repair: long-term follow-up of a randomized controlled trial.

BACKGROUND: We have conducted a randomized controlled trial of totally extraperitoneal hernia repair (TEP) versus tension-free open repair (Lichtenstein repair); we have presented the results previously up to 1 year after the operation. The aim of this study was to compare patient outcome in both groups at a median follow-up of 7.3 years after operation. METHODS: Of 168 patients included in a pros

A computational model for understanding stem cell, trophectoderm and endoderm lineage determination

Background. Recent studies have associated the transcription factors, Oct4, Sox2 and Nanog as parts of a self-regulating network which is responsible for maintaining embryonic stem cell properties -- self renewal and pluripotency. In addition, mutual antagonism between two of these and other master regulators have been shown to regulate lineage determination. In particular, an excess of Cdx2 over
