Photopyroelectric spectroscopy of polyaniline films (2000)

Photopyroelectric spectroscopy (PPES), in the 400 < λ < 900 nm wavelength range, was used to study thermal properties of differently doped polyaniline (PAN) films. The photopyroelectric intensity signal Vn(λ) and its phase Fn(λ) were independently measured, as well as the intensity Vn(f) and the phase Fn(f) (f being the chopping frequency) for a given λ of the saturation part of the PPES spectrum. Equations of both the intensity and the phase of the PPES signal, taking into account the thermal and the optical characteristics of the PAN films and the pyroelectric detector, were used to fit the experimental results. From the fittings we obtained, with great accuracy, the values of thermal conductivity k and thermal diffusivity coefficient α of PAN films of different doping degrees. It was observed that, in contrast with the strong doping-dependence of the electrical conductivity, the thermal parameters of PAN films remained practically unchanged under doping. This apparent discrepancy is explained by the granular metal model of doped PAN. © 2000 John Wiley & Sons, Inc. J Polym Sci B: Polym Phys 38: 1294–1300, 2000
Keratinolytic potential of<i>Bacillus licheniformis</i>RG1: structural and biochemical mechanism of feather degradation (2005)

Keratinolytic Bacillus licheniformis RG1 was used to study the mechanism of keratinolysis. Scanning electron microscopy studies revealed that bacterial cells grew closely adhered to the barbules of feathers, completely degrading them within 24 h. Biochemical studies indicated that the Bacillus strain produced an extracellular protease, which had keratinolytic potential. The extracellular keratinolytic activity (425 U) was synergistically enhanced by the addition of intracellular disulfide reductases (1712 U). However, these enzymes alone (keratinase and disulfide reductase), without live bacterial cells, failed to degrade the feather. Complete feather degradation was obtained only when living bacterial cells were present, emphasizing that bacterial adhesion plays a key role during the degradation process. The bacterial cells probably provide a continuous supply of reductant to break disulfide bridges. In addition, sulfite detected in the extracellular broth during feather degradation indicated that sulfitolysis may also play a role in feather degradation by the bacterium.
Staffing and management of e-commerce programs and projects (2005)

Electronic commerce (e-commerce) personnel are instrumental in developing and maintaining electronic commerce programs and projects within firms. In spite of the dot-com bust, the number of firms developing and using e-commerce for interactions with customers and suppliers is growing. Personnel competence as individuals and as a group can be a decisive force in determining the level of success of e-commerce projects. This paper used in-depth interviews toward creating a better understanding of broad concepts and values in this area. More specifically, it examines the management and staffing of e-commerce projects in terms of how work is organized, which organizational unit governs e-commerce programs and management, how staff are assigned to projects and what skills are critical, and how outcomes are measured. Significant variance was identified in each of these areas.
Modelling of steric structure of a periplasmic molecular chaperone Caf1M of Yersinia pestis, a prototype member of a subfamily with characteristic structural and functional features (1995)

Steric structure of Caf1M, a periplasmic molecular chaperone of Yersinia pestis, was reconstructed by computer modelling based on a statistically significant primary structure homology between Caf1M and PapD protein from Escherichia coli, and using the known atomic coordinates obtained by the X-ray crystallography for PapD. In the three-dimensional model of Caf1M an accessory sequence between F1 and G1 β-strands (as compared to PapD) can form a strain-specific part of the binding pocket of surface organell subunits. This accessory sequence decreases the depth of the binding pocket. The characteristic structural feature of the subfamily of periplasmic molecular chaperones with the accessory sequence (Caf1M subfamily) is the existence of exposed to a solvent Cys residues in F1 and G1 β-strands which can form disulfide bond in the putative binding pocket. The characteristic functional feature of Caf1M subfamily is the chaperoning of more simple compositions of virulence-associated surface organells (in the case of Y. pestis a capsule consists of only F1 protein). Highly conserved R82 and D93, located at the domain surface remote from the putative subunit binding pocket, can participate in direct contacts with the conserved portion of molecular usher proteins.
[Abrasion reducing polyethylene ceramic-metal compound hip prosthesis head]. (1995)

There are two specific problems in using metallic or ceramic heads for hip prostheses: (1) the amount of polyethylene abrasions in the cup caused by the heads (especially a metal head). (2) the polyethylene abrasions caused by Al2O3 ceramic heads is far less than metal heads, but its ability to adapt geometrically is limited due to its being less strong. The abrasions appear because of geometric differences in the prosthetic joint, local problems in the surface architecture and physical/chemical interactions between the different materials. In this study we compare the new "Titan-Niob Ceramic Multilayer Sandwich Head" (built three layers of microsegregation phases and three in-between layers of ultrathin metal, 8-10 microns thick, and a surface with integrated grease holes) with the common CoCrMo heads and Al2O3 ceramic heads. Testing 2,000,000 cycles in a bodylike liquid under permanent loads of 90 kPa, periodically increasing up to 250 kPa, simulating normal stress situations (i.e., walking), the "Titan-Niob Ceramic Multilayer Sandwich Head" showed major advantages over the metal heads and also over the ceramic heads even though the ceramic head has been accepted so far to have the best friction coefficient. Furthermore, there has been no problem in surface fracture with the "Titan-Niob Ceramic Multilayer Sandwich Head".
Des‐gamma‐carboxyprothrombin detection by immunoblotting after polyacrylamide gel affinoelectrophoresis in human plasmas (1991)

In the absence of vitamin K or in the presence of the vitamin K antagonists, abnormal nonfunctional forms of prothrombin circulate in the blood. A reliable and reproducible technique, derived from traditional crossed affinoimmunoelectrophoresis in presence of calcium lactate, was developed and optimized. The technique is based on nondenaturing polyacrylamide gel affinoelectrophoresis, with calcium lactate, of plasma samples, followed by immunoblotting with rabbit anti-human prothrombin serum and detection with an anti-rabbit immunoglobulin peroxidase conjugate. Depending on the plasmas, one or two bands were visualized and quantified by densitometry of the immunoblots. The technique was able to detect abnormal des-gamma-carboxylated prothrombins at concentration of 0.1 microgram/mL.
HIV and employee benefits: where to from here? (1997)

The HIV epidemic is well-established in South Africa. It is even possible that the prevalence of HIV could reach higher levels in South Africa than in most other countries due to the combination of poor communities living in a country with highly developed patterns of urbanization, labor mobility, civil unrest, and an efficient transport infrastructure. About 10% of South Africa's adult population is infected with HIV and there could be more than 100,000 AIDS cases before the year 2000. Since most AIDS cases occur among young adults, there will definitely be an impact upon the employed. The normal mortality rate for working adults will double over the next 5 years. Employee benefits, labor relations, and the risk for retirement funding are discussed. The author concludes that until cost-effective treatment for HIV/AIDS becomes available, most South African employees can expect a continuous reduction in the value of their employee benefits. It is up to the retirement funding industry to find creative solutions to escalating employee benefit costs without being unfairly discriminatory.
Differential Effect of 5-Bromodeoxyuridine on the Concentrations of Specific Enzymes in Hepatoma Cells in Culture (1971)

Growth of cultured rat hepatoma cells in the presence of 5-bromodeoxyuridine results in a rapid inhibition of the synthesis of adrenal steroid-inducible tyrosine aminotransferase (EC 2.6.1.5) and slower decreases in the concentrations of lactate dehydrogenase (EC 1.1.1.27), alcohol dehydrogenase (EC.1.1.1.1), and glucose-6-phosphate dehydrogenase (EC 1.1.1.49). During the same period, neither overall cell growth nor the concentrations of malate dehydrogenase (EC 1.1.1.37), acid phosphatase (EC 3.1.3.2), or alanine aminotransferase (EC 2.6.1.2) were significantly decreased by the base analog. Addition of thymidine to the growth medium rapidly counteracts the inhibition of tyrosine aminotransferase synthesis but restores the normal concentrations of lactate-, alcohol-, and glucose-6-phosphate dehydrogenases much more slowly. Growth of the cells for only one generation in the presence of bromodeoxyuridine, followed by the addition of thymidine, produces transient decreases in the concentrations of the three "late-responding" dehydrogenases, beginning 2-3 generations after exposure to the analog.It is concluded that the selective inhibitory effects of the analog could result from a mechanism in which bromodeoxyuridine is uniformly incorporated into cellular DNA, but inhibits the transcription of only certain genes into messenger RNA. A mathematical model is derived to account for the observed differences in the kinetics of the inhibition of synthesis of the gene products that are sensitive to the analog.

Chikungunya in Southeast Asia: understanding the emergence and finding solutions (2011)

In the last few years, chikungunya has become a major problem in Southeast Asia, with large numbers of cases being reported in Singapore, Malaysia, and Thailand. Much of the current epidemic of chikungunya in Southeast Asia is being driven by the emergence of a strain of chikungunya virus that originated in Africa and spread to islands in the Indian Ocean, as well as to India and Sri Lanka, and then onwards to Southeast Asia. There is currently no specific treatment for chikungunya and no vaccine is available for this disease. This review seeks to provide a short update on the reemergence of chikungunya in Southeast Asia and the prospects for control of this disease.

Synthesis of glycoconjugates derived from various lipopolysaccharides of the Vibrionaceae family (1989)

Conjugation of simple ketoses (such as 3-deoxy-D-manno-2-octulosonic acid and N-acetylneuraminic acid) and of various O-specific polysaccharides (from Aeromonas hydrophila and Aeromonas salmonicida) to the bifunctional spacer 1,6-hexanediamine, was achieved by reductive amination. The saccharide--1-(6-amino)-hexane alkyamines obtained were converted into the corresponding isothiocyanate derivatives and coupled to the free epsilon-amino group of lysine residues of the protein carrier bovine serum albumin. In similar manner, the aldehyde group introduced by selective periodate oxidation into the partially O-deacylated lipopolysaccharide of Vibrio anguillarum was conjugated to 1,6-hexanediamine, converted into the corresponding isothiocyanate and covalently attached to bovine serum albumin.

Dual-band filter based on non-degenerate dual-mode slow-wave open-loop resonators (2009)

This paper presents a new class of dual-band filters based on non-degenerate dual-mode microstrip slow-wave open-loop resonators, which support two non-degenerate modes that do not couple. Different feed schemes that affect the filtering characteristics are investigated. Examples of dual-band filters of this type are described with simulation and experiment results.
‘Looking Away’: Private Writing Techniques as a Form of Transformational Text Shaping in Art & Design and the Natural Sciences (2016)

Despite their long history and wide-spread use, the private writing techniques of journaling and freewriting remain largely underexploited in the field of academic writing instruction. They are seen only as forms of pre-writing, and are criticised by some for being under-theorised, vague and asocial. Contextualizing them within a writing-as-social-practice approach, and drawing on a conceptual framework including a notion of looking-away developed by Derrida, Vygotsky’s conception of learning development, and Ivanic’s notion of writer identity, this paper aims to throw new light on these private writing techniques and argues they can be transformational in developing students’ learning and identity, as well as written and non-written outputs. In this paper we theorise these practices through reflection on two instances of teaching in which they played an important part. The teaching interventions were in different disciplinary contexts (Architectural Design and Natural Sciences), with writers of different levels of expertise/competence (undergraduate and PhD), in both L1 and multilingual settings. In both interventions, we found that these private writing techniques were transformational due to the space they allowed writers to self-reflect, and to look away from their public-facing outputs. The techniques provided significant developmental benefits and moved the students along a continuum towards a more expert-like identity.

Conventions collectives et extension juridique (2014)

Après avoir brièvement fait l'exposé de l'évolution historique de la Loi de la convention collective depuis son adoption en 1934 et de la Loi des relations ouvrières de 1944, l'auteur examine successivement la matière, l'autorité et l'application de ces deux lois. Toutes deux présentent des difficultés de fait dans leur application et amènent ainsi des divergences de vue patronales-ouvrières. Comment concilier ces deux régimes ? Là réside le problème. Le lecteur trouvera dans cet article une solution possible envisagée en regard de la loi, des nécessités syndicales et de certains aspects économiques et deux remèdes d'application immédiate possible.
La sociedad de la información: ¿fenómeno derivado del cambio social o mito? (2004)

En los ultimos diez anos pocos conceptos han despertado tanta admiracion a la hora de hablar de sociedad, economia y tecnologia como “la sociedad de la informacion”. Los expertos hablan de las maravillosas posibilidades que ofrece el sector de las telecomunicaciones y de la informatica. Las nuevas tecnologias hacen variar nuestro nivel de vida permitiendo que siempre se nos pueda localizar, ofrecen puestos de trabajo y aseguran asi la continuidad del bienestar. Pero, ?cumple la sociedad de la informacion sus promesas? Para resolver esta cuestion hay que tratar primero lo extraordinario del concepto en si. ?Que es la sociedad de la informacion en realidad? ?Han desencadenado los avances tecnologicos un cambio social? ?En que consiste dicho cambio? Parece ser que tanto la informacion como la comunicacion han cobrado mayor importancia en nuestras vidas. La informacion y la comunicacion han sido siempre muy importantes para la humanidad. Pero entonces, ?que tienen las nuevas tecnologias del sector de las telecomunicaciones y de la informatica para despertar tal fascinacion capaz de provocar una transformacion social? A simple vista, se entiende la sociedad de la informacion en primer lugar como el desarrollo de las tecnologias de las comunicaciones. Debido a que cada vez se emplean mas las tecnologias digitales, se han ido sustituyendo las estructuras comunicacionales ya existentes por otras nuevas. Pero, ?comprende esto la esencia de la sociedad de la informacion?, ?sabemos hacia donde nos lleva o estamos dando vueltas en circulo?

Problem decomposition and subgoaling in artificial neural networks (2002)

A general principle of problem decomposition and subgoaling is proposed for designing an artificial neural network (ANN) and its learning algorithms. The basic idea is divide-and-conquer. The principle is explored systematically, and it is shown through several examples that it should benefit the design of ANN and its learning algorithms in general. Three types of subgoal decomposabilities are identified: serial, parallel, and diameter-limited. It is shown that the scaling-up difficulties and that of decoding what structure to use for a problem may be solved or alleviated using the subgoal decomposition principle. A learning algorithm based on the principle is developed for training multilayer perceptrons to classify any nonlinearly separable clusters. Convergence to the correct classification is guaranteed if the patterns are separable. The algorithm simultaneously learns the structure and connection weights of the network. >
Computational Approach to Investigate Similarity in Natural Products Using Tanimoto Coefficient and Euclidean Distance (2010)

Both capsicum and ginger are hot spices. Capsaicin present in the capsicum is responsible for its spiciness. The characteristic odor and flavor of ginger is due to the presence of zingerone. Vanillin is the principal compound responsible for flavor and aroma in vanilla. Eugenol has applications in perfumeries, flavorings and in medicine as a local antiseptic and anesthetic. The structures of all the four substances look remarkably similar. According to similarity property principle, structurally similar molecules tend to have similar properties. Similar molecules exert similar biological activities. However, there is no hard and fast rule that the similar chemical structure compounds will have similar functions. There are several similar chemical structure compounds which demonstrate that chemically similar compounds may have significantly different biological actions and activities. Structure similarity study of capsaicin and vanillin, capsaicin and eugenol, zingerone and vanillin, zingerone and eugenol, vanillin and eugenol, and capsaicin and zingerone investigated using Tanimoto Coefficient (TC) and Euclidean Distance (ED) measurements showed that vanillin and eugenol have highest similarity, while capsaicin and vanillin have least similarity. To investigate TC and ED measurements, first all the four molecules are decomposed into smaller fragments. A dictionary of the fragments is prepared. Using this dictionary 2D fingerprints are formed and using the fingerprints TC and ED are quantified by a program code implemented in MATLAB3 R2007b.
