RELATIONSHIP BETWEEN CYTOGENETIC FINDINGS AND HISTOPATHOLOGY IN NON‐HODGKIN LYMPHOMA

The cytogenetic findings in 70 patients with non‐Hodgkin lymphoma have been correlated with tumor histopathology according to the Kiel classification. Certain chromosome aberrations displayed a nonrandom association with the grade of malignancy: 4 lymphomas out of 6 with 1p+, 5 out of 7 with del(6)(q15), 7 out of 11 with 14q+, and 5 out of 8 with +18 belonged to the high grade malignancy group, wh

Prognostic implication of cytogenetic findings in 106 patients with non-Hodgkin lymphoma

The cytogenetic findings in samples from 106 patients with non-Hodgkin lymphomas (NHL), histopathologically classified according to the Kiel classification, have been correlated with survival time. Clonal chromosomal abnormalities were found in 60 patients, and only normal karyotypes in ten. The chromosome analysis of the remaining samples failed. The failures did not differ in survival compared w

Normal frequency of structural chromosome aberrations in fibroblasts from patients with non‐Hodgkin's lymphoma

The incidence of chromosome aberrations, i.e., chromatid and chromosome gaps, breaks, and exchanges, was studied in cultured skin fibroblasts from 25 untreated patients with non‐Hodgkin's lymphoma (NHL) and 26 controls. The mean frequencies of aberrant cells, and gap, break, and gap+break events per 100 metaphases were 4.2, 1.9, 2.8, and 4.7 in the NHL group, and 5.1, 2.6, 3.2, and 5.8 in the cont

Influence of left atrial size on P-wave morphology : differential effects of dilation and hypertrophy

Aims: Chronic left atrial enlargement (LAE) increases the risk of atrial fibrillation. Electrocardiogram (ECG) criteria might provide a means to diagnose LAE and identify patients at risk; however, current criteria perform poorly. We seek to characterize the potentially differential effects of atrial dilation vs. hypertrophy on the ECG P-wave. Methods and results: We predict effects on the P-wave

Lumped-parameter grey-box modelling of traction machines for low-speed operation

This paper presents a procedure to derive a thermal lumped-parameter grey-box model of an electric machine built for traction. The procedure includes experimental data logged under overload conditions for accurate temperature prediction at high currents, and features a relatively simple loss estimation approach. Validation of the model shows a good fit between measured and simulated results. Possi

Model of air cooled windings for traction machine

This article presents a concept of direct cooled windings for electrical machines, pumping air through hollow rectangular copper windings. The thermal constraints pose a serious limitation in the performance of many applications of electrical machines, not least in electrical vehicles. The difference between temporary maximum output and continuous output is often substantial. This difference can b

Power Losses and Heat Extraction in a Stator with Directly Air-Cooled Laminated Windings

This paper explores and assesses power loss generation and heat extraction in a stator with directly air-cooled laminated winding. An electrical machine winding made of an electric conducting sheet, which have slotted structure for accommodating a magnetic core, is denoted a laminated winding. A space is introduced between the conducting sheets so that the heating power is removed right where it i

Direct Conductor Cooling in Concentrated Windings

This paper presents and assesses the cooling integration of electrical machines with concentrated windings. A conventional coil in a concentrated winding with forced cooling applied on the exterior coil surfaces is replaced by an alternative solution where the coil is opened up in a laminar structure with the intention of the coolant fluid penetrating the coil and removing the interior heat. This

Urban form, demographic and socio-economic correlates of walking, cycling, and e-biking : Evidence from eight neighborhoods in Beijing

This paper explores the urban form, demographic and socio-economic dependencies of walking, cycling and e-biking in Beijing based on a survey (N = 1427) of daily travel among residents in eight neighborhoods, enriched with urban form variables. The results show that walking is most frequently used, followed by cycling, which in turn is more frequent than e-biking. Walking and cycling are preferred

Key Performance Indicators in Manufacturing Operations Management : A Case Study of the IS022400-Standard Applied at Volvo Cars

The ISO 22400 has defined a set of Key Performance Indicators (KPIs) to evaluate the performance of manufacturing operation. Though the calculation formulas and tendency analysis of KPIs are given in the standard, it is important to evaluate how the standard performs when implemented in an industrial setting. Based on analyzing the production process in Volvo car, an aggregation KPI evaluation sys

Bicycle-friendly infrastructure planning in Beijing and Copenhagen - between adapting design solutions and learning local planning cultures

Cities around the world are constructing bicycle infrastructure to increase cycling. However, identifying efficient design solutions and determining how bicycle infrastructure planning knowledge can be integrated into comprehensive policy remains a challenge. The objective of this paper is to shed light on the strengths and weaknesses of current bicycle infrastructure planning in both an experienc

Peer engagement for teaching and learning: competence, autonomy and social solidarity in academic microcultures

University teachers’ engagement in teaching is a crucial aspect for the quality of student learning. In this article, we explore where such engagement comes from. We use a sociocultural perspective to investigate how teachers’ colleagues and leaders, in what we call academic microcultures, influence such engagement.

Continuous experimentation scenarios : A case study in e-commerce

Controlled experiments on software variants enable e-commerce companies to increase sales by providing user-adapted functionality. Our goal is to understand how the context of experimentation influences tool support. We performed a case study at Apptus that develops algorithms for e-commerce. We investigated how the case company uses experiments through five semi-structured interviews. We identifi

The Spatio-Temporal Development of Copenhagen’s Bicycle Infrastructure 1912-2013

Cycling plays an important role in low-carbon transitions. Around the globe, cities are constructing bicycle infrastructure. The city of Copenhagen has a bicycle-friendly infrastructure celebrated for its fine-meshed network. This study documents the spatio-temporal development of Copenhagen’s bicycle infrastructure and explores how the development corresponds to other processes of urban transform

Understanding the preconditions for revitalizing bicycle transport in Beijing, with a reference study from Copenhagen

Rapid urbanization and the growth in the number of motorized vehicles has dramatically marginalized cycling in Chinese cities since the end of the 1990s. The deterioration in air quality and the urban environment is severely challenging urban livability and public health. The cities are seeking effective policies to alleviate these problems, and revitalizing bicycle transport has received increasi
