Achieving Rapid Knowledge Acquisition in a High- Volume Call Centre (2005)

Ripple Down Rules (RDR) has been applied to a number of domains. In this paper we consider a new application area that presents a number of new challenges. Our application is a high-volume call centre that provides a service / help desk function in a complex problem domain. We propose that the combined use of multiple classification ripple-down-rules (MCRDR) together with a web-enabled hyperlinkrich browser front-end will provide an effective tool to help call-centre knowledge workers cut through the potential information overload presented by both intraand inter-nets; speed up the processes of knowledge acquisition and re-use; and assist with decision support and problem resolution. We consider the implementation issues faced by corporations in their transition from a simple call / defect-tracking model to a much enriched knowledge-centered model and we examine the role MCRDR can play in the call-centre context including workflow integration, accessibility, usability, and incentives. In order to improve the fit with our application area, we suggest a number of variations to the MCRDR theme. Our implementation and evaluation of these ideas is ongoing.
Advance selling and internet intermediary (2007)

We investigate two challenges advance of e-commerce creates for traditional practice of travel distribution. First, we explore whether travel providers benefit from strategically controlling the timing to start advance selling. Second, we study when should travel providers use Internet intermediaries, in particular, should they promote or limit Internet intermediaries' distribution power? We find that the best timing for travel providers to start advance selling depends on the type of demand uncertainty they face. When the key uncertainty is spot demand, travel providers should not start advance selling too early if they expect higher advance selling price in later period. When travel providers face demand uncertainty in both advance and spot periods, they are worse off not using the advance channel; whether they should start advance selling early depends on advance and spot price, and demand ration between advance and spot periods. In studying travel providers' strategic position of whether to promote or limit Internet intermediary's distribution power, we find that when both parties possess the same quality of demand information, travel providers should always limit intermediary's distribution power under pure forwards contract; when the two parties possess different quality of information, the informational advantages of one party over the other plays a critical role. Surprisingly, in our model setting, travel providers should limit intermediary's distribution power when the latter has more accurate demand information or when the former have a slightly better informational advantage over the intermediary. Otherwise, when travel providers have a huge informational advantage over the intermediary, they should promote the intermediary.
Tolerances of barley cultivars to post-emergence herbicides (1986)

Sixteen spring barley cultivars were tested in southern New South Wales for their tolerances to 12 post-emergence herbicides applied at the recommended rates and at three times those rates. Examples of unsafe combinations of cultivars and herbicides (at recommended rates) that have a risk of crop damage in this environment include: Shannon with bromoxynil at 0.42 kg/ha; Panvan with bromoxynil plus MCPA at 0.42 + 0.42 kg/ha; Bandulla, Beecher, Clipper, Malebo, Panvan and Weeah with dicamba at 0.08 kg/ha; and Clipper, Galleon, Lara and Shannon with dicamba plus MCPA at 0.11 + 0.48 kg/ha. Severe damage occurred to barleys from diclofop-methyl at 0.56 kg/ha and from chlorsulfuron at 0.01 8 kg/ha. Cultivars which showed tolerance were Grimmett, Lara, Stirling and Shannon with chlorsulfuron, and Shannon and Weeah with diclofop-methyl. The use of rates three times those recommended by the manufacturers in these experiments identified the susceptibility of additional cultivars which could be at risk of crop damage from overdosing, incorrect timing of application, or adverse environmental conditions. For example, Lara and Corvette with bromoxynil at 1.26 kg/ha; Corvette and Shannon with bromoxynil plus MCPA at 1.26 + 1.26 kg/ha; Corvette, Cutter, Galleon, Lara, Panvan, Schooner, and Shannon with dicamba plus MCPA at 0.33 + 1.44 kg/ha. The grain yields ofall cultivars were unaffected by both rates of difenzoquat, diuron, linuron, methabenzthiazuron or 2,4-D. The risks of crop damage v. the benefits of weed control are discussed. Seasonal variation was observed in the herbicidexcultivar interactions and this variation was sometimes of a greater magnitude than the differences between the cultivars. An interaction was observed between the incidence of barley leaf scald (Rhynchosporium secalis) and treatment with chlorsulfuron or diclofop-methyl. Routine screening of herbicides and crop cultivars for dangerous interactions is recommended, and we need a greater understanding of the effects of environmental factors on plant responses to herbicides.
CHEMICAL VAPOR DEPOSITION OF TiB<sub>2</sub>FOR TiN-TiB<sub>2</sub>LAMINAR COMPOSITES (1991)

Abstract TiB2 is a material with very interesting properties with respect to erosion and corrosion resistance. Deposition on metallic substrates using TiCI4, BBr3 or BCI3 and H2 at temperatures around 900° C results in coronation of the substrate, which is most severe when using BBr3. Therefore, a TiN diffusion barrier is applied. Here we discuss the deposition of TiB2 using BCI3 on molybdenum and TiN and compare the results with those of the thermodynamically more favorable reaction with BBr3. Smooth TiB2 layers are formed when using BCI3, with faceting occurring above 900° C. The morphology seems to be independent of the BCI3/TiCl4 ratio in the gas phase for values between 0·5 and 4. With an excess of boron in the gas phase - BCI3/TiCl4 = 8, depletion occurs already at 800° C. An apparent activation energy of 210 KJ/mol has been determined for a stoichiometric gas phase with BCl3/TiCI4 = 2. When the supply of boron is limiting - BCl3/TiCl4 = 0·5, the activation energy is 120 KJ/mol.
Contact and photocontact allergy in persistent light reactivity (1984)

The patient group consisted of 18 elderly male patients with persistent light reactivity who were subjected to extensive phototesting with different wavelengths, including patch and photopatch testing. All reacted adversely to ultraviolet light and some also to longer wavelengths when tested on normal appearing skin. 17 patients showed contact or photocontact reactions, of which 12 were positive photopatch test reactions and 11 were plain contact reactions. Contact allergy to constituents of oak moss and different lichen compounds was twice as common as allergy to Compositae oleoresins. 72 patients with chronic polymorphic light eruption were used as a control group. 10 of these patients had either a positive photopatch test reaction or a plain contact allergy. Patients with persistent light reactivity are characterized by a particular susceptibility to develop a delayed-type hypersensitivity. They frequently have both photo and plain contact allergy, often to substances used in cosmetics. In 13 of 16 patients in whom a biopsy was carried out, the histology supported the clinical diagnosis. In none of the biopsies was the picture diagnostic in itself. This underlines the inadequacy of light microscopy as the only diagnostic procedure.
Geography in German Literature (1951)

The reflection of the natural environment in the literature of different lands fascinates the geographer and lover of literature. Every writer has to live somewhere and rare is the author who does not receive messages from nature, mountains, seas, brooks, rivers, hills, meadows, woods, trees, flowers, and animals. These live again in his writings; they may be frankly described or modified by poetic mood, hidden or apparent as mainsprings of characters or events. Most natural events are tied so much to a certain location that the description of a fog, a snowstorm, the arrival of spring, the beginning of fall, the morning in the forest, the moonlight by a lake to mention just a few will vary in tone and even in vocabulary with different regions of the world. One does well to know the country of a literature in order to understand the literature of a country.
Generation of hollow conic beams using a metal axicon mirror (2007)

We propose and demonstrate generation of hollow conic beams using a new element—a metal axicon mirror. A good-quality hollow conic beam was generated from a Gaussian laser beam with high conversion efficiency. We also show that by focusing the hollow conic beam with suitable lenses, it is possible to obtain a weakly converging hollow beam for which the diameter remains between 1 and 3 mm over a propagation distance of about 10 cm, which should be of interest for atom-guiding applications. In the focal region, a nearly nondiffracting central spot of size 13 µm (FWHM) was observed for a propagation distance of 8 mm.
Effect of rearing substrate on growth performance, waste reduction efficiency and chemical composition of black soldier fly (<scp><i>Hermetia illucens</i></scp>) larvae (2018)

Vegetable and fruit wastes and winery by-products can be used as rearing substrates for BSF larval mass production. Brewery by-products led to very promising larval performance and nutritional composition. However, given BRE limited availability, low BRE dietary inclusion levels could be used with the purpose of increasing larval performance. © 2018 Society of Chemical Industry.

In this paper, we present, Kaleidoscope, a cloud platform for multimedia streaming on mobile devices, enhanced with textual and touch-display interactions for a rich user experience. We evaluate the Kaleidoscope system on two different clouds at different locations, testing the streaming quality, and CPU and memory usage, using different numbers of clients.
Matrix Tablets of Carrageenans. II. Release Behavior And Effect of Added Cations (1999)

Carrageenans are hydrocolloids in the rubbery state at standard conditions. They are useful excipients for controlled-release tablets. Three carrageenans, two kappa-carrageenans (Gelcarin GP-812 NF and GP-911 NF) and one iota-carrageenan (Gelcarin GP-379 NF), are analyzed regarding their release behavior in combination with sorption, swelling, and rheology. The iota-carrageenan has a higher substitution by sulfate groups. The kappa-carrageenan Gelcarin GP-812 NF contains a small amount of potassium chloride left over from processing. Water sorption of the pure materials was studied gravimetrically, and the rheology of different solutions (2% and 5% w/w) was studied by cup-cylinder rotation viscosimetry. Swelling was determined as the vertical expansion of the tablets with a specially designed swelling apparatus. Drug release from the tablets was performed by the USP paddle method for 8 hr. The data indicate that drug release increases when water sorption and swelling extent decrease and as viscosity increases. The order of release is nearly zero-order kinetics for theophylline monohydrate, a nonionic drug. Diffusion of the anionic drug diclofenac sodium is anomalous. In addition, the influence of the added salts potassium and calcium chloride on swelling and release was studied. Before tableting, physical mixtures of these salts with and without theophylline monohydrate were prepared. Swelling and release change in the same order, but this is only valid when the ionic interactions responsible for this are strong enough. Besides this, physical mixing of salts with the carrageenans can result in an increased release of drug caused by decreased cohesion of the matrix during drug release, mainly for calcium chloride.
Experimental Statistics in Entomology. F. M. Wadley. Washington, D. C.: Graduate School Press: U.S. Department of Agriculture, 1967. viii, 132 pp. $6.50. (2017)

Excerpt: This book "is intended to help entomological workers who have a real interest, but little training. in applying statistical methods to research problems." The author has proceeded under the false assumption that removal of all mathematical precision and the elimination of the rationale behind statistical techniques results n simplification and clarification. This presents an insoluble dilemma to the statistically uninformed reader.
Spezifische Einsatzgebiete von PC’s in Kreditinstituten (1991)

Der Einsatz modernster Computertechnologie ist für die Abwicklung der zumeist transaktionsorientierten und schnellen Handelsgeschäfte von großer Bedeutung.1 Dies gilt vor allem im internationalen Bankgeschäft, weil dort der Wettbewerb zwischen den Banken am stärksten ausgeprägt ist und die Kunde-Bank-Verbindung nur durch eine günstige Konditionsgestaltung aufrechterhalten werden kann.2

Natal Homing in a Marine Fish Metapopulation (2001)

Identifying natal origins of marine fishes is challenging because of difficulties in conducting mark-recapture studies in marine systems. We used natural geochemical signatures in otoliths (ear bones) to determine natal sources in weakfish (Cynoscion regalis), an estuarine-spawning marine fish, in eastern North America. Spawning site fidelity ranged from 60 to 81%, comparable to estimates of natal homing in birds and anadromous fishes. These data were in contrast to genetic analyses of population structure in weakfish. Our findings highlight the need for consideration of spatial processes in fisheries models and have implications for the design of marine reserves in coastal regions.
Creating a Safe Passage: The Meaning of Engagement for Nurses Caring for Children and their Families (1994)

The purpose of this study was to uncover the meaning of engagement for nurses who care for children and their families. This study employed a hermeneutic-phenomenological methodology as specified by van Manen (1984, 1990) and Ray (1991). A convenience sample consisted of eight nurses who worked in a pediatric ambulatory care setting. Data were generated from audiotaped interviews and journaling. The first level of reflection revealed the themes and metathemes of the meaning of engagement: Making Connection: Becoming Aware of the Person; Perceiving the Other: Developing and Nurturing the Relationship; A Sense of Investment: Unfolding From Commitment; and Remaining Distant: Choosing Not To Engage. In the second level of reflection selected literature further illuminated the meaning of engagement. Through deeper reflection, the metaphor Creating a Safe Passage surfaced to capture the meaning of engagement. This research supports the transformation of health care delivery toward a greater emphasis on the caring relationship. Findings illuminate specific characteristics of an engaged relationship. Implications for sensitizing health care professionals in practice, education, and research are described.
Botnet Research Survey (2008)

Botnets are emerging threat with hundreds of millions of computers infected. A study shows that about 40% of all computers connected to the internet in the world are infected bots and controlled by attackers. This article is a survey of recent advances in botnet research. The survey classifies the botnet research into three areas: understanding botnets, detecting and tracking botnets, and defending against botnets. While botnets are widespread, the research and solutions for botnets are still in their infancy. The paper also summarizes the existing research and proposes future directions for botnet research.
A Case of NSAID Induced Small Bowel Ulcer Bleeding Diagnosed by Capsule Endoscopy. (2003)

The small intestine has always been a problematic segments for endoscopic exploration in patients with obscure gastrointestinal bleeding. Recent emergence of capsule endoscopy has entailed a relevant diagnostic imaging advance for gastrointestinal conditions. Capsule endoscope can be used to detect small bowel bleeding. Some studies report that capsule endoscopy has the high diagnostic yield and is superior to enteroscopy and other diagnostic methods. We report here the first case of small bowel bleeding detected by using capsule endoscope in Korea, in woman with hematochezia and a history of aspirin ingestion.

Preparation and Characterization of Active SiO2 from Cymbopogon citratus Ash Calcined at Different Temperature (2016)

Cymbopogon citratus or lemon grass, is a potential renewable herbaceous biomass alternative. Lemon grass contains silica, which is available for extraction as a filler for various applications. Lemon grass ash is produced at calcination temperatures of 0, 400, 525, 600, and 700 ˚C. The silica content of the lemon grass ash was characterized by X-ray fluorescence (XRF), X-ray powder diffraction (XRD), scanning electron microcopy (SEM), and Fourier transform infrared (FTIR) analysis. The shape and texture of the lemon grass ash were studied by SEM. The highest silica content recorded was 24.00% for lemon grass calcined at 400 °C. The porosity of the lemon grass ash increased as the calcination temperature increased from 0 °C to 700 °C. XRD analysis showed that the crystallinity of silica in the lemon grass ash increased with increasing calcination temperature. FTIR analysis confirmed the presence of organic structure in lemon grass without calcination and the inorganic structure of siloxane and silanol bonds present in lemon grass calcined at different temperatures.

Unfolding intermediates of the extracellular domain of the interferon gamma receptor. (1992)

Reduction of proteins which require disulfide bonds to be stable in the folded state is accompanied by step-wise unfolding. A soluble human interferon gamma receptor produced in Escherichia coli was used to investigate the kinetics of formation of unfolding intermediates. The protein includes 8 cysteine residues forming four disulfide bonds. It was reduced by using either dithiothreitol or the thioredoxin reduction system. Reduction with dithiothreitol resulted in formation of mainly four monomeric unfolding species as visualized by sodium dodecyl sulfate-polyacrylamide gels. The enzymatically catalyzed reaction produced only small amounts of two monomeric products and mostly delivered oligomeric and polymeric forms. In both cases, the ligand binding capacity of the receptor was significantly reduced immediately after appearance of the first intermediate. The intermediates involved interchange of disulfide bonds and did not show ligand binding capacity. Some of them were recognized by specific antibodies which detect conformational epitopes on the native interferon gamma receptor. On the basis of the antibody binding, a preliminary characterization of the formed intermediates was attempted. When the soluble receptor was reduced in the presence of denaturing agents, the reduction products were different from the unfolding intermediates generated in the absence of denaturants.
Suppression of Hard Bubbles in Magnetic Garnet Films by Ion Implantation (1972)

Hard bubbles are cylindrical magnetic domains which differ from normal bubbles in their static and dynamic properties. <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">1–3</sup> They form and collapse at fields considerably higher than normal bubble domains (hence the name “hard bubbles”) and, under the action of a gradient in the perpendicularly directed magnetic field, they have a component of motion either to the right or to the left rather than straight down the gradient (right- and left-handed hard bubbles). Under the influence of a small alternating field superimposed on the dc bias field, normal bubbles oscillate in size or strip out in a random manner, whereas hard bubbles tend to strip out in an S-shape and rotate in either a counterclockwise direction for the normal S-shape or clockwise for the reverse S-shape. It has been found that high-speed propagation using permalloy overlay circuits is impossible in materials which are prone to hard bubble formation.
Association of the <i>angiotensinogen</i> M235T polymorphism with recurrence after catheter ablation of acquired atrial fibrillation (2015)

The M allele of M235T might be associated with an increased risk of AF recurrence after CA. Genotyping may thus be helpful on identifying patients with higher risks of AF recurrence after CA and developing optimal follow-up strategies. These strategies may differ and should be individualized according to patients' genotype. Future studies are warranted to validate the potential effect of AGT M235T on AF recurrence post CA.
[Effect of cobalamin derivatives on DNA synthesis in cells of Propionibacterium freudenreichii subsp. shermanii]. (1987)

The increase of DNA-synthesis rate (according incorporation [8-14C]adenine) in B12-deficient cells Propionibacterium shermanii as a result of different cobalamines adding into the cell suspension including metoxyethyladenile analog of adenozilcobalamin and some components of vitamin B12 molecule has been found. The DNA-synthesis rate in B12-deficient cells is nearly twice lower as compared with one in B12-normal cells. Considerable stimulative effect (80-100%) was provided with coenzyme forms of cobalamin. The data confirm the participation of vitamin B12 in DNA-synthesis in Propionibacterium cells.
