A fully integrated digitally controlled phase-locked loop (PLL) used as a clock multiplying circuit is designed and fabricated. The PLL has no off-chip components and it is made from standard cells found in most digital standard cell libraries. The design is, therefore, portable between technologies as an IP block. Using a 0.35-mum standard CMOS process and a 3.0-V supply voltage, the PLL has a fr
The Children’s Revised Impact of Event Scale (CRIES) is a brief child-friendly measure designed to screen children at risk for Posttraumatic Stress Disorder (PTSD). It has good face and construct validity, a stable factor structure, correlates well with other indices of distress, and has been used to screen very large samples of at-risk-children following a wide range of traumatic events. However,

We conducted a first pilot study on healthy women living in two countries with different dietary habits, Granada in the south of Spain and Malmo in the south of Sweden, in order to compare their levels of plasma phospholipid fatty acids, and to examine the relationship between the differences in food consumption. This study is part of a pilot study which is nested in the European Prospective Inves
The purpose of this work is to address the issue of applicability of single-molecule spectroscopy (SMS) results for conjugated polymers to "bulk" samples, e.g. conjugated polymer films. Also, some apparent inconsistencies in the literature on SMS regarding the photoluminescence spectral position of conjugated polymers are discussed. We present a series of photoluminescence spectra of thin films of
The field of biosensors for measuring biochemical oxygen demand (BOD) is reviewed. Particularly, BOD sensors constructed on the biofilm configuration are discussed regarding performance characteristics like linearity, response time, precision, agreement between BOD values obtained from the biosensors and the conventional 5-days test, as well as toxic resistance to various compounds and operational

To define the early cytogenetic events important in esophageal carcinogenesis, we immortalized normal esophageal epithelial cells by overexpression of human papillomavirus type 16 E6/E7 (HPV16E6/E7) and human telomerase reverse transcriptase (hTERT), and characterized the chromosomal abnormalities serially before and after Cellular immortalizaiton. During crisis. most cells had simple nonclonal ka
Measurement of S-phase fraction by DNA flow cytometry is widely used in the analysis of human tumors. The calculation of fraction of S-phase cells is performed either by means of curve-fitting techniques or by more simple planimetric methods. Estimates by the latter often suffer from subjectivity or poor adaptation to complex DNA histograms. We describe a variant which is based on the rectangular
Phylogenetic analyses were carried out on 23 samples representing 10 cetrarioid taxa from Europe and North America, representing 10 cetrarioid taxa; they were compared in parsimony analyses. The study is focused on ITS sequences of the ribosomal DNA. Intervening sequences, most likely representing group I introns, were found in four taxa. The results from the phylogenetic analysis are congruent wi
Electrochemical properties of two multiforms of laccase from Trametes pubescens basidiomycete (LACI and LAC2) have been studied. The standard redox potentials of the T1 sites of the enzymes were found to be 746 and 738 mV us. NHE for LACI and LAC2, respectively. Bioelectroreduction of oxygen based on direct electron transfer between each of the two forms of Trametes pubescens laccase and spectrogr
Flow cytometric (FCM) DNA ploidy measurements on frozen fresh samples of soft tissue sarcomas were compared with the corresponding analyses on preoperative fine needle aspirates and postoperative formalin-fixed archival tissues from the same tumors. A concordance in ploidy status (diploid versus non-diploid) was obtained for 63% of the fresh tissue-fine needle aspiration (FNA) sample comparisons a
This study aimed to describe and analyse self-rated health in relation to sense of coherence and socioeconomic and health-related factors and to explore the associations between self-rated health and these factors in order to identify health resources and health limitations in a group of healthy middle-aged women. Healthy middle-aged women from a defined geographical area in Southern Sweden ( n =5
Popular Abstract in Swedish Laser Doppler metoder avsedda för mätning av blodflöde baserar sig på det faktum att fotoner skiftar i våglängd när de träffar blodkroppar i rörelse. Den förändrade våglängden registreras och signalen bearbetas varefter resultatet uttrycks i en godtycklig enhet och anses utgöra ett mått på blodflöde. Laser Doppler Perfusion Monitoring (LDPM) är en metod med vilken blodThe operating principle of all laser Doppler methods is based on the fact that incident photons shift in wavelength when interacting with moving blood cells passing through the microvascular network. After photodetection and further signal processing, the recorded parameter can be considered an arbitrary measure of tissue blood flow, and this is referred to as ?perfusion?. Laser Doppler perfusion
A theoretical model is established for diffusion of different types of ions in pore solution of concrete and the coupling to moisture flow and moisture content. Mass exchanges between ions in pore solution and solid hydration products in the concrete are also considered. The basic concepts behind the so-called mixture theory are used.
