To accomplish timing recovery/synthesis in high-speed communication systems, a 24-b numerically controlled oscillator (NCO) IC using a circuit design technique called true single-phase clock (TSPC) pipelined CMOS has been fabricated in a standard 1.2-μm CMOS process. The device achieves a maximum tested input clock rate of 700 MHz, which results in an output frequency tuning range from DC up to 35

The aim of this study was to validate the Edholm scale (Edholm, 1966) and the ISO 8996 standard (International Organization for Standardization [ISO], 1990) by comparing the metabolic rates estimated for both methods with the actual measured metabolic rate (MMeas) in 6 manual material handling tasks simulated under laboratory conditions. The metabolic rate was calculated from oxygen consumption VO

Objective – The role of the academic librarian has become increasingly educative in nature. In this study, the critical friend method was introduced among teaching librarians in an academic setting of medicine and health sciences to ascertain whether this approach could be implemented for feedback on teaching of these librarians as part of their professional development. Methods – We used a singl

The optical spectra of a quantum cascade laser structure under nonequilibrium conditions is studied using the technique of nonequilibrium Green functions. We focus on the impact of Coulomb corrections and their dependence on the operating conditions. The role of the static mean field due to the charge distribution by electrons and ioninzed donors is investigated.

Objective: Compare perioperative course and long-term mortality after liver resection for colorectal cancer (CRC) metastases between patients who had preoperative treatment with portal vein embolization (PVE) and chemotherapy or chemotherapy alone. Methods: Among patients undergoing liver resection for CRC metastases following preoperative chemotherapy treatment, 17 patients who had received pre

Controlled resistive loads can contribute to damping of electro-mechanical oscillations. This paper presents an on-off damping controller for a single machine system. It was used at a field test in Southern Sweden to damp oscillations of a 0.9 MW hydro power generator. The controller used estimated machine frequency as input and controlled a 20 kW resistive load via thyristor switches. The field m

INTRODUCTION: As more patients survive coronary events, the prevalence of patients with refractory angina pectoris is increasing. The aim was to evaluate the effects of enhanced external counterpulsation (EECP) and spinal cord stimulation (SCS) and compare with optimal medically treated patients with refractory angina. METHODS: 153 patients with refractory angina were treated with either EECP, SCS

n this study, Jordanian feldspar from Wadi Al-Jayshiah area was invested to evaluate its applicability as raw material for ceramic and industries. The chemical analysis indicated that the average Fe2O3 content is 2.33%, which is very high, compared to commercial ceramic and glass grades feldspar. The SiO2 content in the Wadi Al-Jayshiah feldspar (67.96%) lies within the required amount in commerci

The importance of the nurse's role in the management of patients with type 2 diabetes has long since been emphasized. The aim of this study was to test the hypothesis that a structured organization of type 2 diabetes care, with a diabetes nurse working more independently of the general practitioner, has a significant impact on the patient's self-management and quality of care. The test consisted o

Standing postural stability relies on input from visual, vestibular, proprioceptive and mechanoreceptive sensors. When the information from any of these sensors is unavailable or disrupted, the central nervous system maintains postural stability by relying more on the contribution from the reliable sensors, termed sensory re-weighting. Alcohol intoxication is known to affect the integrity of the v

This paper describes the development of two test formats, COLLEX and COLLMATCH, measuring receptive recognition knowledge of English verb +NP collocations, and reports findings from pilots and initial test administrations involving Swedish upper-secondaryschool and university level learners. Administrations of the test formats produced highly reliable scores and the performance of native speakers

Disorders affecting the central nervous system have proven particularly hard to treat and disappointingly few of novel therapies have reached the clinics in the last decades. A better understanding of the physiological processes in the brain underlying various symptoms could therefore greatly improve the rate of progress in this field. We here show how systems level descriptions of different brain

Schumpeter, Dahmén, Schön, Freeman, and other evolutionary scholars have shown that economic transformation and technological change are necessary prerequisites for long-term economic growth. However, for the Swedish case the exact sectoral and regional anatomy of the technology shift taking place since 1978 has not yet been disentangled. In this thesis, a disaggregation of the national process is
