Opis:
It is known that the procedure called Grade Correspondence Analysis (GCA) transforms any bivariate contingency table into an approximation of table with a very regular positive dependence, called total positivity of order two (TP2). This fact is reminded in Sections 2 and 3, illustrated there by the GCA transformation of an artificial contingency table [T_8x6]. A search for rows and/or columns of table [T_8x6], which most strongly outlie from the TP2 pattern, is described in Section 4. Section 5 presents the outliers found in three large contingency tables, containing the occupational mobility data from Britain and Poland and the parliamentary election data from Poland.

Opis:
This study focused on developing a new approach to seated work positions as conducted on 67 office workers who use a Visual Display Terminal (VDT) as a major function of their working day. Muscle tension was measured by surface electromyography (sEMG) while participants were asked to adopt 4 selected working postures. Pain was measured before and after ergonomic intervention on the Nordic scale, which was modified for this study. Adjustable workstations were used to place participants in desired positions during the clinical testing sessions and the extended intervention period. Results indicate the effects of this ergonomic intervention may have positive effects on muscle tension and pain, significant enough to encourage employers to implement training and workstation modifications following these guidelines.

Opis:
A new method for the fabrication of field emission arrays (FEA) based on bulk/surface silicon micromachining and diamond-like-carbon (DLC) coating was developed. A matrix of self-aligned electron field emitters is formed in silicon by mean anisotropic etching in alkali solution of the front silicon film through micro holes opened in silicon oxide layer. The field emission of the fabricated emitter tips is enhanced by a diamond-like-carbon film formed by chemical vapor deposition on the microtips. Back side contacts are formed by metal patterning. Detailed Raman, Auger and TEM investigations of the deposited DLC films (nanocrystalline diamond smaller than 10 nm) will be presented. In this paper we discuss the problems related to the development of field emission arrays technology. We also demonstrate examples of devices fabricated according to those technologies.

Opis:
The in vitro protein biosynthesis has the potentials to become a powerful technology for biochemical research. Beside the determination of structure and function the in vitro evolution of proteins is also of great interest. The system described was used to produce bovine heart fatty acid binding protein (FABP) and bacterial chloramphenicol acetyltransferase (CAT) with and without fusion of the Strep-tag II affinity peptide. The proteins were purified after and during protein biosynthesis by using a StrepTactin Sepharose matrix. No significant influence of the Strep-tag and the conditions during the affinity chromatography on maturation or activity of the protein was observed. The in vitro evolution of proteins is feasible by means of ribosome display. The selection of a specific mRNA coding for a shortened FABP with a N-terminal His-tag via the accompanying protein property was shown. Goal of the selection was to bind the FABP via the His-tag on Ni(II)-IDA-agarose. After nine cycles of transcription, translation, affinity selection and RT-PCR the protein with the His-tag could be enriched 108-fold. In order to correlate a possible relationship between changes in protein population and biological function studies were initiated in which 2-dimensional protein patterns of the total in vitro system were compared after 0 and 2 h reaction time. The very interesting findings are that a number of proteins disappear, while others are newly formed during protein synthesis.

Opis:
Augmented Reality uses Head Mounted Displays (HMD) to overlay the real word with additional virtual information. Virtual Retinal Displays (VRD), a new display technology, no longer requires Liquid Crystal Displays (LCD). VRD technology addresses the retina directly with a single laser stream of pixels. There are no studies on the user’s informational strain in this new VRD technology. Various papers have shown that Heart Rate Variability (HRV) is a valid indicator for the user’s informational strain. An empirical test revealed no difference in the user’s HRV between VRD technology and LCD technology. Consequently, there seems to be a comparable user informational strain regarding the display types.

Opis:
The systemic inflammatory reaction (acute phase response) is induced by many noxious stimuli but in all cases the inflammatory cytokines, such as interleukin-1-beta (IL-1β) and interleukin-6 (IL-6), are involved. Liver cell response to inflammation manifested by a characteristic change in the profile of synthesized plasma proteins (acute phase proteins) has been extensively studied. Here we describe a model system of cultured human hepatoma HepG2 cells stimulated with IL-1β to evaluate the transcriptome induced by this cytokine during 24 h of treatment. By using differential display analysis we found IL-1β-induced upregulation of several genes coding for cellular trafficking/motor proteins, proteins participating in the translation machinery or involved in posttranscription/posttranslation modifications, proteases, proteins involved in cellular metabolism, activity modulators, proteins of the cell cycle machinery and also some new proteins so far functionally not classified.

Opis:
This paper introduces preventive measures against Deep Vein Thrombosis (DVT) during Visual Display Units (VDU) work. Four experiments were conducted in order to address this issue. The effectiveness of the preventative measures was evaluated by measuring foot swelling. The results indicated that the following 3 methods would be particularly effective: (a) occasionally adopting a reclining posture with a footrest, (b) 10-min walking every 50–60 min of VDU work, and (3) stretching. In addition we predicted that taking a deep breath could sometimes be effective. DVT is likely to occur in daily life and its incidence can be related to the long-term postures associated with VDU work. This paper suggests that VDU workers should be aware of the risk of DVT and take preventative measures.

Implementation of new services in the network requires appropriate methods and tools for checking correctness of interworking between terminals and exchanges. In this article the methodology and test procedures prepared for testing terminals handling FSK protocol transmitted over the local loop for display and related services was described. Methodology presented here is based on ETSI standards. Test procedures were developed for services offered in Polish network. Tests cover all levels of FSK protocol. For two lower layers, separate procedures for ^on-hook" and "off-hook" loop states were prepared. The procedure for "on-hook" state contains tests related to data transmission "associated" and "not associated with ringing". These procedures cover normal cases with parameter values and sequence elements complying with standards and exceptional procedures with the extreme values of the parameters and with modified elements of the sequences.

Opis:
A phage-displayed random 7-mer disulfide bridge-constrained peptide library was used to map the surface of the RhoA GTPase and to find peptides able to recognize RhoA switch regions. Several peptide sequences were selected after four rounds of enrichment, giving a high signal in ELISA against RhoA-GDP. A detailed analysis of one such selected peptide, called R2 (CWSFPGYAC), is reported. The RhoA - R2 interaction was investigated using fluorescence spectroscopy, chemical denaturation, and determination of the kinetics of nucleotide exchange and GTP hydrolysis in the presence of RhoA regulatory proteins. All measurements indicate that the affinity of the R2 peptide for RhoA is in the micromolar range and that R2 behaves as an inhibitor of: i) GDP binding to the apo form of RhoA (Mg2+- and nucleotide-free form of the GTPase), ii) nucleotide exchange stimulated by GEF (DH/PH tandem from PDZRhoGEF), and iii) GTP hydrolysis stimulated by the BH domain of GrafGAP protein.

The era of maps and the World Wide Web spans less than a decade and a half and it is already characterized by widely divergent, almost polarizing, areas of development. These sharp contrasts are evident in the available file formats for online maps, sever/client relationships, commercial vs. open source software, desktop vs. mobile Internet access, and the widely divergent savvy of the user audience. To better understand how maps are being transformed for the Internet, and what future developments might be, it is necessary to recognize these sharply contrasting areas of development.

Opis:
PDZ domains are ubiquitous protein-protein interaction modules which bind short, usually carboxyterminal fragments of receptors, other integral or membrane-associated proteins, and occasionally cytosolic proteins. Their role in organizing multiprotein complexes at the cellular membrane is crucial for many signaling pathways, but the rules defining their binding specificity are still poorly understood and do not readily explain the observed diversity of their known binding partners. Two homologous RhoA-specific, multidomain nucleotide exchange factors PDZRhoGEF and LARG contain PDZ domains which show a particularly broad recognition profile, as suggested by the identification of five diverse biological targets. To investigate the molecular roots of this phenomenon, we constructed a phage display library of random carboxyterminal hexapeptides. Peptide variants corresponding to the sequences identified in library selection were synthesized and their affinities for both PDZ domains were measured and compared with those of peptides derived from sequences of natural partners. Based on the analysis of the binding sequences identified for PDZRhoGEF, we propose a sequence for an 'optimal' binding partner. Our results support the hypothesis that PDZ-peptide interactions may be best understood when one considers the sum of entropic and dynamic effects for each peptide as a whole entity, rather than preferences for specific residues at a given position.

Subject performance in reading characters on mobile phone liquid crystal displays was researched by using (a) English sentences with 3 or 4 different sizes of characters on 2 types of displays with different resolutions (n = 23; age = 31.0 ± 6.0 years), (b) Japanese characters in 3 different sizes and 2 types of font (n = 98; age = 44.5 ± 18.5 years), and (c) Japanese characters vertically enlarged 1–4 times (n = 120; age = 46.9 ± 18.6 years). Subjective evaluation, reading speed, number of reading errors, and viewing distance were recorded. Readability was higher with higher resolution displays, and with Gothic than with Mincho font in Japanese. Young subjects shortened the viewing distance as characters became smaller, whereas elderly subjects increased the viewing distance irrespective of the size of characters. Characters of 3–5 mm are appropriate for the young but inadequate for the elderly. Readability of Japanese characters improved when they were vertically enlarged to approximately twice the width.
