Até onde sabemos, este é o primeiro relato de cirurgia para paresia do reto medial na síndrome de Lambert-Eaton.

Gaps of free-space optics beams with the Beer-Lambert law.

Science.gov (United States)

Lacaze, Bernard

2009-05-10

Lasers used in free-space optics propagate a beam within a truncated cone. Because of this shape, the intensity cannot follow the Beer-Lambert law. In the case of a homogeneous atmosphere, we calculate the gap from the cylinder case. We will see that the gap exists but is generally very weak and, therefore, that the use of the Beer-Lambert law is a justified approximation.

Plant protection based on novel alternative strategies is a major concern in agriculture to sustain pest management. The marc extract of red grape cultivars reveals plant defence inducer properties. Treatment with grape marc extract efficiently induced hypersensitive reaction-like lesions with cell death evidenced by Evans Blue staining of tobacco leaves. Examination of the infiltration zone and the surrounding areas under UV light revealed the accumulation of autofluorescent compounds. Both leaf infiltration and a foliar spray of the red grape extract on tobacco leaves induced defence gene expression. The PR1 and PR2 target genes were upregulated locally and systemically in tobacco plants following grape marc extract treatment. The grape extract elicited an array of plant defence responses making this natural compound a potential phytosanitary product with a challenging issue and a rather attractive option for sustainable agriculture and environmentally friendly practices.

Unified Lambert Tool for Massively Parallel Applications in Space Situational Awareness

Science.gov (United States)

Woollands, Robyn M.; Read, Julie; Hernandez, Kevin; Probe, Austin; Junkins, John L.

2018-03-01

This paper introduces a parallel-compiled tool that combines several of our recently developed methods for solving the perturbed Lambert problem using modified Chebyshev-Picard iteration. This tool (unified Lambert tool) consists of four individual algorithms, each of which is unique and better suited for solving a particular type of orbit transfer. The first is a Keplerian Lambert solver, which is used to provide a good initial guess (warm start) for solving the perturbed problem. It is also used to determine the appropriate algorithm to call for solving the perturbed problem. The arc length or true anomaly angle spanned by the transfer trajectory is the parameter that governs the automated selection of the appropriate perturbed algorithm, and is based on the respective algorithm convergence characteristics. The second algorithm solves the perturbed Lambert problem using the modified Chebyshev-Picard iteration two-point boundary value solver. This algorithm does not require a Newton-like shooting method and is the most efficient of the perturbed solvers presented herein, however the domain of convergence is limited to about a third of an orbit and is dependent on eccentricity. The third algorithm extends the domain of convergence of the modified Chebyshev-Picard iteration two-point boundary value solver to about 90% of an orbit, through regularization with the Kustaanheimo-Stiefel transformation. This is the second most efficient of the perturbed set of algorithms. The fourth algorithm uses the method of particular solutions and the modified Chebyshev-Picard iteration initial value solver for solving multiple revolution perturbed transfers. This method does require "shooting" but differs from Newton-like shooting methods in that it does not require propagation of a state transition matrix. The unified Lambert tool makes use of the General Mission Analysis Tool and we use it to compute thousands of perturbed Lambert trajectories in parallel on the Space Situational

A novel implementation of mARC treatment for non-dedicated planning systems using converted IMRT plans

International Nuclear Information System (INIS)

Dzierma, Yvonne; Nuesken, Frank; Licht, Norbert; Ruebe, Christian

2013-01-01

The modulated arc (mARC) technique has recently been introduced by Siemens as an analogue to VMAT treatment. However, up to now only one certified treatment planning system supports mARC planning. We therefore present a conversion algorithm capable of converting IMRT plans created by any treatment planning system into mARC plans, with the hope of expanding the availability of mARC to a larger range of clinical users and researchers. As additional advantages, our implementation offers improved functionality for planning hybrid arcs and provides an equivalent step-and-shoot plan for each mARC plan, which can be used as a back-up concept in institutions where only one linac is equipped with mARC. We present a feasibility study to outline a practical implementation of mARC plan conversion using Philips Pinnacle and Prowess Panther. We present examples for three different kinds of prostate and head-and-neck plans, for 6 MV and flattening-filter-free (FFF) 7 MV photon energies, which are dosimetrically verified. It is generally more difficult to create good quality IMRT plans in Pinnacle using a large number of beams and few segments. We present different ways of optimization as examples. By careful choosing the beam and segment arrangement and inversion objectives, we achieve plan qualities similar to our usual IMRT plans. The conversion of the plans to mARC format yields functional plans, which can be irradiated without incidences. Absolute dosimetric verification of both the step-and-shoot and mARC plans by point dose measurements showed deviations below 5% local dose, mARC plans deviated from step-and-shoot plans by no more than 1%. The agreement between GafChromic film measurements of planar dose before and after mARC conversion is excellent. The comparison of the 3D dose distribution measured by PTW Octavius 729 2D-Array with the step-and-shoot plans and with the TPS is well above the pass criteria of 90% of the points falling within 5% local dose and 3 mm distance

Full Text Available The LIBER MARC Harmonization Task Force has its origins in an initiative of the past President of LIBER, Professor Elmar Mittler from the Göttingen State and University Library. Professor Mittler asked Dr Elisabeth Niggemann from Die Deutsche Bibliothek to take part in the meeting of the MARC Harmonization Coordinating Committee in Ottawa in May 2001. Following that meeting the LIBER MARC Harmonization Task Force was founded at the LIBER Annual Conference in July 2001 in London. The LIBER MARC Harmonization Task Force held its first meeting on 14 January 2002 at Die Deutsche Bibliothek Frankfurt am Main, with the aim of gaining an overview of format activities in Europe. The group's aim was to concentrate on European developments and to build up stronger cooperation in the library world in order to strengthen Europe's international influence. The LIBER MARC Harmonization Task Force held a second meeting at the IFLA 2002 Conference in Glasgow and discussed the first draft of its report and recommendations to LIBER. After final discussion within the group, this report has been further revised and was submitted to LIBER. The aim of the report is to give an overview of format activities in European countries and to make recommendations to LIBER regarding the use and development of data formats in Europe. The annex includes reports on migration activities from different countries. The report is based on information on data formats collected and compiled on the basis of a questionnaire distributed to the Conference of European National Librarians (CENL. Cataloguing issues were further discussed at the 1st IFLA Meeting of Experts on an International Cataloguing Code held in Frankfurt in July 2003. Further meetings will be held at the IFLA conferences in Buenos Aires (2004 and Seoul (2006.

Can the Lamberts and Lambert Submaximal Cycle Test Reflect Overreaching in Professional Cyclists?

Science.gov (United States)

Decroix, Lieselot; Lamberts, Robert P; Meeusen, Romain

2018-01-01

The Lamberts and Lambert Submaximal Cycle Test (LSCT) consists of 3 stages during which cyclists cycle for 6 min at 60%, 6 min at 80%, and 3 min at 90% of their maximal heart rate, followed by 1-min recovery. To determine if the LSCT is able to reflect a state of functional overreaching in professional female cyclists during an 8-d training camp and the following recovery days. Six professional female cyclists performed an LSCT on days 1, 5, and 8 of the training camp and 3 d after the training camp. During each stage of the LSCT, power output and rating of perceived exertion (RPE) were determined. Training diaries and Profile of Mood States (POMS) were also completed. At the middle and the end of the training camp, increased power output during the 2nd and 3rd stages of the LSCT was accompanied with increased RPE during these stages and/or the inability to reach 90% of maximal heart rate. All athletes reported increased feelings of fatigue and muscle soreness, while changes in energy balance, calculated from the POMS, were less indicative of a state of overreaching. After 3 d of recovery, all parameters of the LSCT returned to baseline, indicating a state of functional overreaching during the training camp. The LSCT is able to reflect a state of overreaching in elite professional female cyclists during an 8-d training camp and the following recovery days.

Gravity discharge vessel revisited: An explicit Lambert W function solution

Science.gov (United States)

Digilov, Rafael M.

2017-07-01

Based on the generalized Poiseuille equation modified by a kinetic energy correction, an explicit solution for the time evolution of a liquid column draining under gravity through an exit capillary tube is derived in terms of the Lambert W function. In contrast to the conventional exponential behavior, as implied by the Poiseuille law, a new analytical solution gives a full account for the volumetric flow rate of a fluid through a capillary of any length and improves the precision of viscosity determination. The theoretical consideration may be of interest to students as an example of how implicit equations in the field of physics can be solved analytically using the Lambert function.

On the Validity of Beer-Lambert Law and its Significance for Sunscreens.

Science.gov (United States)

Herzog, Bernd; Schultheiss, Amélie; Giesinger, Jochen

2018-03-01

The sun protection factor (SPF) is the most important quantity to characterize the performance of sunscreens. As the standard method for its determination is based on clinical trials involving irradiation of human volunteers, calculations of sunscreen performance have become quite popular to reduce the number of in vivo studies. Such simulations imply the calculation of UV transmittance of the sunscreen film using the amounts and spectroscopic properties of the UV absorbers employed, and presuppose the validity of the Beer-Lambert law. As sunscreen films on human skin can contain considerable concentrations of UV absorbers, it is questioned whether the Beer-Lambert law is still valid for these systems. The results of this work show that the validity of the Beer-Lambert law is still given at the high concentrations at which UV absorbers occur in sunscreen films on human skin. © 2017 The American Society of Photobiology.

2012-01-01

We present a new grid of model photospheres for the SDSS-III/APOGEE survey of stellar populations of the Galaxy, calculated using the ATLAS9 and MARCS codes. New opacity distribution functions were generated to calculate ATLAS9 model photospheres. MARCS models were calculated based on opacity sampling techniques. The metallicity ([M/H]) spans from –5 to 1.5 for ATLAS and –2.5 to 0.5 for MARCS models. There are three main differences with respect to previous ATLAS9 model grids: a new corrected H 2 O line list, a wide range of carbon ([C/M]) and α element [α/M] variations, and solar reference abundances from Asplund et al. The added range of varying carbon and α-element abundances also extends the previously calculated MARCS model grids. Altogether, 1980 chemical compositions were used for the ATLAS9 grid and 175 for the MARCS grid. Over 808,000 ATLAS9 models were computed spanning temperatures from 3500 K to 30,000 K and log g from 0 to 5, where larger temperatures only have high gravities. The MARCS models span from 3500 K to 5500 K, and log g from 0 to 5. All model atmospheres are publicly available online.

Three-dimensional protein shape rendering in magnetized solution with Lambert-Beer law.

Science.gov (United States)

Gu, HongYan; Chang, WeiShan

2012-07-10

When monochromatic light passes through a homogeneous absorbing medium, the absorbance is proportional to the growth of concentration and thickness of the medium, which is the Lambert-Beer law. The shade selection of protein solution magnetized for a certain time from different angles makes different absorbance, which does not meet the Lambert-Beer law. Accordingly, we derive that the absorbance A is not only proportional to the concentration and thickness of the medium but also proportional to the light area S(S) of a certain direction. For the same protein solution, we can obtain the absorbance A of six directions and thus get six values for S(S) the relative ratio of which will inevitably reveal plentiful information of the protein shape. The conformation of the protein can be easily drawn out by software (MATLAB 7.0.1). We have drawn out the molecular shape of lysozyme and bovine serum albumin. In brief, we have developed the Lambert-Beer law A=K·C·b·S(s) and a new method of exploring protein spatial structure.

Highlights: • BioMethane Potential of grape marcs was investigated. • Grape marcs were characterized to realize a micro-scale energy recovery. • Comparative BMP batch-tests utilizing lab-scale reactors were performed. • Biogas valorization by grape marcs anaerobic digestion at small scale is evaluated. - Abstract: The BiochemicalMethanePotential (BMP) of winery organic waste, with reference to two Italian red and white grapes (i.e. Nero Buono and Greco) by-products was investigated. The study was carried out to verify the possibility to reduce the production impact in a green-waste-management-chain-perspective. The possibility to efficiently utilize wine-related-by-products for energy production at a micro-scale (i.e. small-medium scale winery production plant) was also verified. Results showed as a good correlation can be established between the percentage of COD removal and the biogas production, as the winery can produce, from its waste methanization, about 7800 kW h year −1 electrical and 8900 kW h year −1 thermal. A critical evaluation was performed about the possibility to utilize the proposed approach to realize an optimal biomass waste management and an energetic valorization in a local-energy-production-perspective

Efficient Underwater RSS Value to Distance Inversion Using the Lambert Function

Directory of Open Access Journals (Sweden)

Majid Hosseini

2014-01-01

Full Text Available There are many applications for using wireless sensor networks (WSN in ocean science; however, identifying the exact location of a sensor by itself (localization is still a challenging problem, where global positioning system (GPS devices are not applicable underwater. Precise distance measurement between two sensors is a tool of localization and received signal strength (RSS, reflecting transmission loss (TL phenomena, is widely used in terrestrial WSNs for that matter. Underwater acoustic sensor networks have not been used (UASN, due to the complexity of the TL function. In this paper, we addressed these problems by expressing underwater TL via the Lambert W function, for accurate distance inversion by the Halley method, and compared this to Newton-Raphson inversion. Mathematical proof, MATLAB simulation, and real device implementation demonstrate the accuracy and efficiency of the proposed equation in distance calculation, with fewer iterations, computation stability for short and long distances, and remarkably short processing time. Then, the sensitivities of Lambert W function and Newton-Raphson inversion to alteration in TL were examined. The simulation results showed that Lambert W function is more stable to errors than Newton-Raphson inversion. Finally, with a likelihood method, it was shown that RSS is a practical tool for distance measurement in UASN.

We present an asymmetric step–barrier potential for which the one-dimensional stationary Schrödinger equation is exactly solved in terms of the confluent hypergeometric functions. The potential is given in terms of the Lambert W-function, which is an implicitly elementary function also known as the product logarithm. We present the general solution of the problem and consider the quantum reflection at transmission of a particle above this potential barrier. Compared with the abrupt-step and hyperbolic tangent potentials, which are reproduced by the Lambert potential in certain parameter and/or variable variation regions, the reflection coefficient is smaller because of the lesser steepness of the potential on the particle incidence side. Presenting the derivation of the Lambert potential we show that this is a four-parametric sub-potential of a more general five-parametric one also solvable in terms of the confluent hypergeometric functions. The latter potential, however, is a conditionally integrable one. Finally, we show that there exists one more potential the solution for which is written in terms of the derivative of a bi-confluent Heun function. - Highlights: • We introduce an asymmetric step-barrier potential for which the 1D Schrödinger equation is exactly solved in terms of confluent hypergeometric functions. • The potential is given in terms of the Lambert-function, which is an implicitly elementary function also known as the product logarithm. • This is a four-parametric specification of a more general five-parametric potential also solvable in terms of the confluent hypergeometric functions. • There exists one more potential the solution for which is written in terms of the derivative of a bi-confluent Heun function.

Correction to the Beer-Lambert-Bouguer law for optical absorption.

Science.gov (United States)

Abitan, Haim; Bohr, Henrik; Buchhave, Preben

2008-10-10

The Beer-Lambert-Bouguer absorption law, known as Beer's law for absorption in an optical medium, is precise only at power densities lower than a few kW. At higher power densities this law fails because it neglects the processes of stimulated emission and spontaneous emission. In previous models that considered those processes, an analytical expression for the absorption law could not be obtained. We show here that by utilizing the Lambert W-function, the two-level energy rate equation model is solved analytically, and this leads into a general absorption law that is exact because it accounts for absorption as well as stimulated and spontaneous emission. The general absorption law reduces to Beer's law at low power densities. A criterion for its application is given along with experimental examples. (c) 2008 Optical Society of America

2015-01-01

Pressurized thermal decomposition of two marine algae, Pinus radiata chip residue and grape marc using high temperature, high pressure reactions has been studied. The yields and composition of the products obtained from liquefactions under CO of a mixture of biomass and H 2 O (with or without catalyst) were compared with products from liquefaction of dry biomass under N 2 , at different temperatures, gas pressures and for CO runs, water to biomass ratios. Thermochemical reactions of algae produced significantly higher dichloromethane solubles and generally higher product yields to oil and asphaltene than Pinus radiata and grape marc under the reaction conditions used. Furthermore, the biofuels derived from algae contained significant concentrations of aliphatic hydrocarbons as opposed to those from radiata pine and grape marc which were richer in aromatic compounds. The possibility of air transport fuel production from algae thus appears to have considerable advantages over that from radiata pine and grape marc. - Highlights: • Liquefaction of algae gave more oil than that of Pinus radiata and grape marc. • Reactions under CO/H 2 O produced higher yields of oil than N 2 . • Water to biomass ratio had little effect on the yields. • Bio-oil from algae contained substantial amounts of aliphatic hydrocarbons. • Pinus radiata oil was low in N but high in O

Generalized Beer-Lambert model for near-infrared light propagation in thick biological tissues

Science.gov (United States)

Bhatt, Manish; Ayyalasomayajula, Kalyan R.; Yalavarthy, Phaneendra K.

2016-07-01

The attenuation of near-infrared (NIR) light intensity as it propagates in a turbid medium like biological tissue is described by modified the Beer-Lambert law (MBLL). The MBLL is generally used to quantify the changes in tissue chromophore concentrations for NIR spectroscopic data analysis. Even though MBLL is effective in terms of providing qualitative comparison, it suffers from its applicability across tissue types and tissue dimensions. In this work, we introduce Lambert-W function-based modeling for light propagation in biological tissues, which is a generalized version of the Beer-Lambert model. The proposed modeling provides parametrization of tissue properties, which includes two attenuation coefficients μ0 and η. We validated our model against the Monte Carlo simulation, which is the gold standard for modeling NIR light propagation in biological tissue. We included numerous human and animal tissues to validate the proposed empirical model, including an inhomogeneous adult human head model. The proposed model, which has a closed form (analytical), is first of its kind in providing accurate modeling of NIR light propagation in biological tissues.

Results showed as a good correlation can be established between the percentage of COD removal and the biogas production, as the winery can produce, from its waste methanization, about 7800 kW h year{sup −1} electrical and 8900 kW h year{sup −1} thermal. A critical evaluation was performed about the possibility to utilize the proposed approach to realize an optimal biomass waste management and an energetic valorization in a local-energy-production-perspective.

An EPR measure of phenolic content in various wine grapeseeds from marc and grapeseed meals left after oil extraction

International Nuclear Information System (INIS)

Jordan, R.

2002-01-01

Full text: Marc is the leftover material (skins, pulp, seeds, stems) from the fermentation mainly of red wines. Owing to the increase in Australian wine production for home and export, and the decrease in Spirits consumption, marc could be in surfeit- Marc seeds for example, still contain oil and tannins which are useful products. So the titular study by EPR was undertaken. Grapeseeds of various varieties were collected on the vine, and from marc after fermentation. The meal remaining from marc seeds after oil extraction was also collected, and climate was taken into account. From this very limited trial, there appears to be no obvious effect of climate on phenolic content. In most cases, the phenolic content of grapeseeds post-winemaking is lower than that pre-winemaking, consistent with the winemaking process significantly affecting phenolic content. For grapeseed meal, in most cases the phenolic content is lower than that of the seeds used to produce the meal. This 'negative' effect of the oil extraction process is consistent with our previously unpublished work (commercial - in - confidence), but is not necessarily economically significant

Branchial cleft anomaly, congenital heart disease, and biliary atresia: Goldenhar complex or Lambert syndrome?

Science.gov (United States)

Cohen, J; Schanen, N C

2000-01-01

The features of Goldenhar complex have been well-described and classically include branchial arch abnormalities, epibulbar dermoid and vertebral abnormalities. We have identified an infant with these features in association with complex congenital heart disease and intrahepatic biliary atresia. Although Lambert described an autosomal recessive disorder with an association of biliary atresia and branchial arch abnormalities, none of those cases had epibulbar dermoid. Diagnostic considerations in this case include inclusion of biliary atresia as a new feature in the expanding spectrum of the Goldenhar complex, versus Lambert syndrome with epibulbar dermoid.

Delay differential equations via the matrix Lambert W function and bifurcation analysis: application to machine tool chatter.

Science.gov (United States)

Yi, Sun; Nelson, Patrick W; Ulsoy, A Galip

2007-04-01

In a turning process modeled using delay differential equations (DDEs), we investigate the stability of the regenerative machine tool chatter problem. An approach using the matrix Lambert W function for the analytical solution to systems of delay differential equations is applied to this problem and compared with the result obtained using a bifurcation analysis. The Lambert W function, known to be useful for solving scalar first-order DDEs, has recently been extended to a matrix Lambert W function approach to solve systems of DDEs. The essential advantages of the matrix Lambert W approach are not only the similarity to the concept of the state transition matrix in lin ear ordinary differential equations, enabling its use for general classes of linear delay differential equations, but also the observation that we need only the principal branch among an infinite number of roots to determine the stability of a system of DDEs. The bifurcation method combined with Sturm sequences provides an algorithm for determining the stability of DDEs without restrictive geometric analysis. With this approach, one can obtain the critical values of delay, which determine the stability of a system and hence the preferred operating spindle speed without chatter. We apply both the matrix Lambert W function and the bifurcation analysis approach to the problem of chatter stability in turning, and compare the results obtained to existing methods. The two new approaches show excellent accuracy and certain other advantages, when compared to traditional graphical, computational and approximate methods.

Filamentous fungi isolated from grape marc as antagonists of Botrytis cinerea

2016-01-01

Full Text Available In this paper we report on the isolation and identification of three filamentous fungi from grape marc, and antifungal effect of their cell-free culture filtrates on the growth of Botrytis cinerea, causal agent of gray mold. Grape marc is a waste material that has been used as soil amendment in sustainable agriculture. Isolates originating from grape marc were identified on the basis of morphological features and internal transcribed spacer rDNA or β-tubulin gene sequencing. The presence of three different species, Penicillium paneum, Penicillium chrysogenum and Aspergillus fumigatus has been detected expressing different effect on the growth of B. cinerea. The effect of crude culture filtrates of selected fungi on B. cinerea growth was tested. Heat sensitivity of the established inhibition effect was examined by autoclaving the crude culture filtrate prior to testing. Additional aim was to determine whether antifungal effect was influenced by previous exposure to B. cinerea in dual liquid cultures. Crude culture filtrate of A. fumigatus K16/2 showed the lowest suppression of B. cinerea growth. A maximal percentage inhibition achieved within the study was 38.2%, 39.8% and 23.8 for crude filtrates of P. paneum K7/1, P. chrysogenum K11/1 and A. fumigatus K16/2, respectively. Presence of B. cinerea in dual liquid culture induced significant increase in antifungal capacity of the culture filtrates in comparison to pure culture filtrates of the chosen isolates. The antifungal activity of all of the isolates’ culture filtrates retained after heat treatment suggesting the presence of some thermostable antifungal metabolites. The results indicate the complexity and specificity of the interaction between filamentous fungi and B. cinerea. Grape marc is a good source for isolation od B. cinerea fungal antagonists and their antifungal metabolites. Specificity of fungal-fungal interactions suggests that further research on the antagonistic mechanisms and

Baker, Wesley B; Parthasarathy, Ashwin B; Busch, David R; Mesquita, Rickson C; Greenberg, Joel H; Yodh, A G

2014-11-01

We develop and validate a Modified Beer-Lambert law for blood flow based on diffuse correlation spectroscopy (DCS) measurements. The new formulation enables blood flow monitoring from temporal intensity autocorrelation function data taken at single or multiple delay-times. Consequentially, the speed of the optical blood flow measurement can be substantially increased. The scheme facilitates blood flow monitoring of highly scattering tissues in geometries wherein light propagation is diffusive or non-diffusive, and it is particularly well-suited for utilization with pressure measurement paradigms that employ differential flow signals to reduce contributions of superficial tissues.

Secondary Aroma Compounds in Fresh Grape Marc Distillates as a Result of Variety and Corresponding Production Technology

2011-01-01

Full Text Available In order to investigate the composition of secondary aroma compounds of fresh grape marc distillates as a result of variety and production technology, 30 samples (6 varieties×5 samples were analysed. White grape marc samples from Malvazija istarska, Chardonnay and Muscat Blanc were obtained as by-products in standard white wine production, while red grape marc samples from Teran and Cabernet Sauvignon were obtained after standard red wine production procedures. Marc from red grape variety Muškat ruža porečki was obtained during the production of rosé wines. All fermented marc samples were distilled using a traditional copper alembic. The obtained distillates were subjected to GC/MS and GC/FID analyses. Malvazija istarska distillates exhibited exceptionally high methanol content. Distillates from white grape varieties were found to be characterized by higher C6 alcohol and 1-propanol concentrations, while red grape distillates contained higher amounts of the majority of alcohols, acids, and esters. In Muškat ruža distillates intermediate concentrations of many important aroma compounds were found. It was concluded that differences in the production technology parameters, depending on the variety, resulted in differences in secondary aroma profiles, most evident between distillates from white and red varieties. These findings were confirmed applying stepwise linear discriminant analysis (SLDA, which resulted in 100 % correct classification of distillates according to the variety and corresponding production technology.

Etica ed evoluzionismo: la proposta di Marc Hauser

Directory of Open Access Journals (Sweden)

Irene Pilloni

2013-11-01

Full Text Available Le recenti scoperte nell’ambito della psicologia evoluzionistica potrebbero offrire una risposta al dibattito sull’origine evoluzionistica della facoltà morale dell’Homo sapiens. In passato, il tentativo di spiegare il comportamento morale a partire dalla teoria dell’evoluzione è stato intrapreso dal padre fondatore dell’evoluzionismo Charles Darwin, successivamente da T.H. Huxley e da H. Spencer e infine dal sociobiologo E. Wilson a metà degli anni ‘70 del Novecento. Oggi questa impresa è stata ereditata dallo psicologo evoluzionista Marc Hauser, le cui indagini prendono avvio da un’analogia tra facoltà morale e facoltà linguistica. Questa analogia gli consente di affermare che la pluralità di codici morali adottati dagli uomini nelle differenti culture dipende da un numero limitato di principi morali, nello stesso modo in cui la varietà di lingue con cui gli uomini si esprimono, dipende da un numero limitato di principi linguistici universali. Dunque, sembrerebbe che l’evoluzione biologica abbia plasmato dei principi morali universali e uniformi che si presentano costanti in tutti gli uomini a prescindere dalla loro appartenenza culturale. Come vadano intesi i principi morali universali e quale rapporto intercorre tra di essi e i vari codici morali sarà l’argomento di questo saggio, il quale tenterà di analizzare la proposta di Marc Hauser all’interno della cornice dei rapporti tra etica ed evoluzionismo.

The Lambert-Beer law holding for pulsed lights transmitted through a scattering medium was examined using a streak camera. The Lambert-Beer law dynamic range is found to be limited by floor levels that are caused by scattered photons and are controllable by the use of a temporal gate on the transmitted pulse. The dynamic range improvement obtained for a scattering medium of 2.8 cm -1 scattering coefficient of a thickness of 80 mm by a temporal gate of 60 ps was as much as 50 dB and the Lambert-Beer law dynamic rang reached to 140 dB.

2010-06-23

To investigate the varietal aroma compound composition of monovarietal grape marc distillates made from six different varieties (Vitis vinifera L.) in the region of Istria (Croatia), 30 samples were subjected to GC/MS and GC/FID analysis. A total of 73 compounds were identified: 45 monoterpenes, 20 sesquiterpenes, 3 diterpenes, and 5 C(13)-norisoprenoids. The largest number and the highest concentration of monoterpenes were found in Muscat Blanc, followed by Rose Muscat of Porec (Muskat ruza porecki) distillates, which were both characterized as highly aromatic. Lower, but still significant monoterpenol content was determined in distillates made from Istrian Malvasia (Malvazija istarska) grape marc. Chardonnay, Cabernet Sauvignon, and Teran distillates exhibited poorer monoterpene profiles, while Teran distillates contained elevated sesquiterpene concentrations. It was concluded that investigated monovarietal grape marc distillates significantly differ in varietal aroma compound composition. Stepwise linear discriminant analysis provided efficient discrimination models, and extracted various monoterpenes, sesquiterpenes and C(13)-norisoprenoids as important differentiators of distillates according to varietal origin.

Using Lambert W function and error function to model phase change on microfluidics

Science.gov (United States)

Bermudez Garcia, Anderson

2014-05-01

Solidification and melting modeling on microfluidics are solved using Lambert W's function and error's functions. Models are formulated using the heat's diffusion equation. The generic posed case is the melting of a slab with time dependent surface temperature, having a micro or nano-fluid liquid phase. At the beginning the solid slab is at melting temperature. A slab's face is put and maintained at temperature greater than the melting limit and varying in time. Lambert W function and error function are applied via Maple to obtain the analytic solution evolution of the front of microfluidic-solid interface, it is analytically computed and slab's corresponding melting time is determined. It is expected to have analytical results to be useful for food engineering, cooking engineering, pharmaceutical engineering, nano-engineering and bio-medical engineering.

Bash, Frank N.

2005-12-01

David Stanley Evans died on 14 November 2004 in Austin, Texas. He was a noted observational astronomer whose career was divided between South Africa and Texas. He also used the extensive historical collections at the University of Texas to write several books on the history of astronomy. He was born in Cardiff, Wales on 28 January 1916. David received his BA degree in mathematics in 1937 from Kings College, Cambridge. He became a PhD student at Cambridge Observatory in 1937, and was one of Sir Arthur Eddington's last surviving students. He received his PhD degree in 1941 with a dissertation entitled, "The Formation of the Balmer Series of Hydrogen in Stellar Atmospheres." He was a conscientious objector to war and, thus, spent the war years at Oxford working with physicist Kurt Mendelssohn on medical problems, involving cadavers, relating to the war. During these years, David was scientific editor of "Discovery", and he was editor of "The Observatory". David left England in 1946 in order to take up the position of Second Assistant at the Radcliffe Observatory, Pretoria, South Africa. He and H. Knox Shaw were the entire staff after R. O. Redman left, and they aluminized and installed the mirrors in the 74-inch telescope. His notable scientific contribution was to use lunar occultations to measure stellar angular diameters during the 1950s. He succeeded in determining the angular diameter of Antares and determined that Arcturus was not circular but had an elliptical shape. The elliptical shape was later shown to be an instrumental artifact, but the utility of using lunar occultations to measure stellar diameters and stellar multiplicity was conclusively demonstrated. T. Gold presented David's paper on lunar occultation angular diameters at the January 1953 meeting of the Royal Astronomical Society. For the rest of his life, David resented Gold's remarks, because he felt that he had been ridiculed. By 1953, David Evans was Chief Assistant at the Royal Observatory

It is with great sadness that we learned that our friend and former colleague, David Warner, passed away on Christmas Eve. The funeral was held the following Monday. David was a "linac man". His career centred around linacs, but with a multitude of different subjects. He began at CERN by building the 3 MeV linac in the extension of the South Hall. He did pioneering work on this machine, which paved the way towards the design of the Alvarez cavities for the CERN Linac 2, for which he was responsible. After this challenge was successfully finished, David was the first member of the small but growing team, that was in charge of building the LEP Injector Linacs (LIL). After having been recognised as a proton linac expert, he quickly converted to electron linacs where he soon became the respected key expert for the design, parameters and ultimate performance of LIL.

Full Text Available There were investigated grape marc spirits regarding their safety on consumers. Major volatile compounds which present risk to human health (such as methanol, furfural, and acetaldehyde and ethyl alcohol content were compared to European Union Regulation and other values found in previous studies.  The aim of our study was to evaluate the safety of grape marc spirits considering their content in major volatile compounds by comparison with the requirements of European Union Regulation. We investigated the ethyl alcohol content by electronic densimetry and 10 major volatile compounds (acetaldehyde, ethyl acetate, methanol, 1-propanol, 1-butanol, 2-butanol, isobutyl alcohol, isoamyl alcohol, amyl active alcohol and furfural by Gas Chromatography coupled with Flame Ionization Detector. We used reference chemicals to identify these compounds and 3-pentanol as internal standard to quantify the volatiles. Results were compared with the requirements of European Union Regulation. All major volatile compounds registered values in accordance to EU Regulation and the grape pomace spirits samples do not present any kind of risk for consumption.

Employing Theories Far beyond Their Limits-The Case of the (Boguer-) Beer-Lambert Law.

Mayerhöfer, Thomas G; Mutschke, Harald; Popp, Jürgen

2016-07-04

For spectroscopists, the (Bouguer-)Beer-Lambert law is unquestionably an essential principle, since it is inseparably linked with one of the most important quantities in spectroscopy, the absorbance. In spite of its importance, a quantitative discussion of the legitimacy of relating the transmittance, the quantity that is usually measured, to the absorbance by assuming a logarithmic relation between both quantities cannot be found in literature. In this contribution, we quantitatively discuss, based on examples, the errors that can be introduced by disregarding the exact solution based on Maxwell's equations and show that these errors can easily exceed one order of magnitude. We also re-derive the Beer-Lambert law, thereby providing guidance as how to convert transmittance into absorbance properly. © 2016 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.

Multiple Revolution Solutions for the Perturbed Lambert Problem using the Method of Particular Solutions and Picard Iteration

Science.gov (United States)

Woollands, Robyn M.; Read, Julie L.; Probe, Austin B.; Junkins, John L.

2017-12-01

We present a new method for solving the multiple revolution perturbed Lambert problem using the method of particular solutions and modified Chebyshev-Picard iteration. The method of particular solutions differs from the well-known Newton-shooting method in that integration of the state transition matrix (36 additional differential equations) is not required, and instead it makes use of a reference trajectory and a set of n particular solutions. Any numerical integrator can be used for solving two-point boundary problems with the method of particular solutions, however we show that using modified Chebyshev-Picard iteration affords an avenue for increased efficiency that is not available with other step-by-step integrators. We take advantage of the path approximation nature of modified Chebyshev-Picard iteration (nodes iteratively converge to fixed points in space) and utilize a variable fidelity force model for propagating the reference trajectory. Remarkably, we demonstrate that computing the particular solutions with only low fidelity function evaluations greatly increases the efficiency of the algorithm while maintaining machine precision accuracy. Our study reveals that solving the perturbed Lambert's problem using the method of particular solutions with modified Chebyshev-Picard iteration is about an order of magnitude faster compared with the classical shooting method and a tenth-twelfth order Runge-Kutta integrator. It is well known that the solution to Lambert's problem over multiple revolutions is not unique and to ensure that all possible solutions are considered we make use of a reliable preexisting Keplerian Lambert solver to warm start our perturbed algorithm.

Quantitative photoplethysmography: Lambert-Beer law or inverse function incorporating light scatter.

Science.gov (United States)

Cejnar, M; Kobler, H; Hunyor, S N

1993-03-01

Finger blood volume is commonly determined from measurement of infra-red (IR) light transmittance using the Lambert-Beer law of light absorption derived for use in non-scattering media, even when such transmission involves light scatter around the phalangeal bone. Simultaneous IR transmittance and finger volume were measured over the full dynamic range of vascular volumes in seven subjects and outcomes compared with data fitted according to the Lambert-Beer exponential function and an inverse function derived for light attenuation by scattering materials. Curves were fitted by the least-squares method and goodness of fit was compared using standard errors of estimate (SEE). The inverse function gave a better data fit in six of the subjects: mean SEE 1.9 (SD 0.7, range 0.7-2.8) and 4.6 (2.2, 2.0-8.0) respectively (p < 0.02, paired t-test). Thus, when relating IR transmittance to blood volume, as occurs in the finger during measurements of arterial compliance, an inverse function derived from a model of light attenuation by scattering media gives more accurate results than the traditional exponential fit.

Transcranial direct current stimulation (tDCS) reveals a dissociation between SNARC and MARC effects: Implication for the polarity correspondence account.

Science.gov (United States)

Di Rosa, Elisa; Bardi, Lara; Umiltà, Carlo; Masina, Fabio; Forgione, Margherita; Mapelli, Daniela

2017-08-01

The concept of stimulus response compatibility (SRC) refers to the existence of a privileged association between a specific stimulus feature and a specific response feature. Two examples of SRC are the Spatial Numerical Association of Response Codes (SNARC) and the Markedness Association of Response Codes (MARC) effects. According to the polarity correspondence principle, these two SRC effects occur because of a match between the most salient dimensions of stimulus and response. Specifically, the SNARC effect would be caused by a match between right-sided responses and large numbers, while a match between right-sided responses and even numbers would give rise to the MARC effect. The aim of the present study was to test the validity of the polarity correspondence principle in explaining these two SRC effects. To this end, we applied transcranial direct current stimulation (tDCS) over left and right posterior parietal cortex (PPC), which is thought to be the neural basis of salience processing, during a parity judgement task. Results showed that cathodal tDCS over the PPC significantly reduced the MARC effect but did not affect the SNARC effect, suggesting a dissociation between the two effects. That is, the MARC would rely on a salience processing mechanism, whereas the SNARC would not. Despite this interpretation is in need of further experimental confirmations (i.e., testing different tasks or using different tDCS montages), our results suggest that the polarity correspondence principle can be a plausible explanation only for the MARC effect but not for the SNARC effect.

2014-01-01

Interferometric Synthetic Aperture Radar (InSAR) is one of the most promising remote sensing technologies and has been widely applied in constructing topographic information and estimating the deformation of the Earth's surface. Ice velocity is an important parameter for calculating the mass balance and modelling ice shelve dynamics. Ice velocity is also an important indicator for climate changes. Therefore, it plays an important role in studying the global climate change and global sea level rise. In this paper, the ERS-1/2 tandem data and the ASTER GDEM are combined together to obtained the deformation in line of sight by using the differential Interferometric SAR for the Lambert Amery glacier in Antarctica. Then the surface parallel assumption is adopted in order to achieve the ice flow velocity. The results showed that ice velocity would be increased along the Lambert glacier; the maximum ice velocity would be reach about 450m/year in the study area

2013-01-01

Henry David Thoreau was wholeheartedly in love with nature and he devoted almost all his life time to observation, appreciation and study of nature. Thus he formed a deep understanding of nature. In 1845, Thoreau began a two-year and two-month residence at Walden Pond. His life was lonely but full of fragrance. He wanted to live meaningfully, confront the essential facts of life and live a simple life. Based on the review of the literature related to this topic, this paper aims to study Henry David Thoreau’s spiritual world, especially reflected in his famous book-Walden.

Identifying FRBR Work-Level Data in MARC Bibliographic Records for Manifestations of Moving Images

Directory of Open Access Journals (Sweden)

Lynne Bisko

2008-12-01

Full Text Available The library metadata community is dealing with the challenge of implementing the conceptual model, Functional Requirements for Bibliographic Records (FRBR. In response, the Online Audiovisual Catalogers (OLAC created a task force to study the issues related to creating and using FRBR-based work-level records for moving images. This article presents one part of the task force's work: it looks at the feasibility of creating provisional FRBR work-level records for moving images by extracting data from existing manifestation-level bibliographic records. Using a sample of 941 MARC records, a subgroup of the task force conducted a pilot project to look at five characteristics of moving image works. Here they discuss their methodology; analysis; selected results for two elements, original date (year and director name; and conclude with some suggested changes to MARC coding and current cataloging policy.

Herbal distillates: A new era of grape marc distillates with enriched antioxidant profile.

2018-07-01

Grape marc distillates are traditional alcoholic beverages, produced mostly in the Mediterranean countries. The present study proposes the enrichment of a Greek traditional grape marc distillate (tsikoudia) with selected herbs to enhance its natural antioxidants and functional properties. Total phenolic content, the antiradical and antioxidant activities, as well as the phenolic and sugar profiles using NMR and FT-IR spectroscopy were evaluated. The enrichment of distillates with Syzygium aromaticum L., Jasminum officinale L. and Eucalyptus globulus Labill. exhibited the highest total phenolic content as well as the highest antioxidant and antiradical activities, whereas the lowest values were observed with Hippophae rhamnoides L. and Lycium Barbarum Mill. The implementation of NMR and FT-IR spectroscopies attested to the presence of phenolic compounds and of specific carbohydrates in herbal distillates, postulating their migration from selected herbal species to tsikoudia and probably contributing to their organoleptic characteristics. The target of this approach leads to new added-value distillates with enhanced characteristics. Copyright © 2018 Elsevier Ltd. All rights reserved.

Multiple-scattering corrections to the Beer-Lambert law

International Nuclear Information System (INIS)

Zardecki, A.

1983-01-01

The effect of multiple scattering on the validity of the Beer-Lambert law is discussed for a wide range of particle-size parameters and optical depths. To predict the amount of received radiant power, appropriate correction terms are introduced. For particles larger than or comparable to the wavelength of radiation, the small-angle approximation is adequate; whereas for small densely packed particles, the diffusion theory is advantageously employed. These two approaches are used in the context of the problem of laser-beam propagation in a dense aerosol medium. In addition, preliminary results obtained by using a two-dimensional finite-element discrete-ordinates transport code are described. Multiple-scattering effects for laser propagation in fog, cloud, rain, and aerosol cloud are modeled

Recent developments of the MARC/PN transport theory code including a treatment of anisotropic scatter

International Nuclear Information System (INIS)

Fletcher, J.K.

1987-12-01

The computer code MARC/PN provides a solution of the multigroup transport equation by expanding the flux in spherical harmonics. The coefficients of the series so obtained satisfy linked first order differential equations, and on eliminating terms associated with odd parity harmonics a second order system results which can be solved by established finite difference or finite element techniques. This report describes modifications incorporated in MARC/PN to allow for anisotropic scattering, and the modelling of irregular exterior boundaries in the finite element option. The latter development leads to substantial reductions in problem size, particularly for three dimensions. Also, links to an interactive graphics mesh generator (SUPERTAB) have been added. The final section of the report contains results from problems showing the effects of anisotropic scatter and the ability of the code to model irregular geometries. (author)

OBTAINING OF PROTEIC BIOMASS BY CULTIVATION OF LACTIC ACID BACTERIA ON GRAPE MARC DIFFUSION SOLUTION

Directory of Open Access Journals (Sweden)

Marian BUTU

2013-08-01

Full Text Available In this article are presented the researches made in order to obtain protein biomass with the aid of lactic bacteria grown on an economically medium, achieved by using secondary products from the winery: marc and wine yeast. Therefore, there were cultivated two strains of Lactobacillus sp. on five different growth medium. The protein biosynthesis and evolution of lactic fermentation were monitored by determining the optical density (OD of the culture at a wavelength λ = 600 nm and by counting the colony forming units (CFU by serial dilutions and seeding on plates and by determination of lactic acid obtained. The results showed that the fermentation medium represented by diffusion solution of the marc, enriched with peptone is economically profitable compared to other culture media containing peptone, yeast extract, glucose, minerals, amino acids and vitamins presented in the literature.

Properties of slate mining wastes incubated with grape marc compost under laboratory conditions.

Paradelo, Remigio; Moldes, Ana Belén; Barral, María Teresa

2009-02-01

The effect of the addition of spent grape marc compost (GMC) and vermicompost (GMV) as amendments to slate mining wastes was evaluated in a laboratory incubation experiment. Mixtures of slate processing fines (SPF), with three doses of each amendment (4%, 8% and 16% compost, dry weight), plus a control were incubated at 25 degrees C in the laboratory for 90 days. The changes in the chemical and biological properties of the mixtures (pH, total C, total N, inorganic N, available nutrients, microbial biomass carbon and dehydrogenase activity) were investigated during the incubation period, and once it was finished, the phytotoxicity of the mixtures was determined by the germination of Lolium multiflorum Lam. seeds. The addition of the amendments significantly increased the nutrient concentrations of the SPF and enhanced biological activity by increasing microbial biomass and enzymatic activity. Results improved with higher doses; within the composts, GMV showed a better performance than GMC. These results prove the suitability of grape marc-derived amendments for the biochemical amelioration of mining wastes, and highlight the benefits of organic amendment in restoration projects.

Glycoprotein 5 of porcine reproductive and respiratory syndrome virus strain SD16 inhibits viral replication and causes G2/M cell cycle arrest, but does not induce cellular apoptosis in Marc-145 cells

Cell apoptosis is common after infection with porcine reproductive and respiratory syndrome virus (PRRSV). PRRSV GP5 has been reported to induce cell apoptosis. To further understand the role of GP5 in PRRSV induced cell apoptosis, we established Marc-145 cell lines stably expressing full-length GP5, GP5 Δ84-96 (aa 84-96 deletion), and GP5 Δ97-119 (aa 97-119 deletion). Cell proliferation, cell cycle progression, cell apoptosis and virus replication in these cell lines were evaluated. Neither truncated nor full-length GP5 induced cell apoptosis in Marc-145 cells. However, GP5 Δ97-119 , but not full-length or GP5 Δ84-96 , induced a cell cycle arrest at the G2/M phase resulting in a reduction in the growth of Marc-145 cells. Additionally, GP5 Δ84-96 inhibited the replication of PRRSV in Marc-145 cells through induction of IFN-β. These findings suggest that PRRSV GP5 is not responsible for inducing cell apoptosis in Marc-145 cells under these experimental conditions; however it has other important roles in virus/host cell biology. - Highlights: • Marc-145 cell lines stable expression PRRSV GP5 or truncated GP5 were constructed. • GP5 Δ97-119 expression in Marc-145 cell induced cell cycle arrest at G2/M phase. • Expression of GP5 and truncated GP5 could not induce Marc-145 cells apoptosis. • PRRSV replication in Marc-145-GP5 Δ84-96 was significantly inhibited

Benchmarking the mARC performance. Treatment time and dosimetric linearity

The mARC technique is a hybrid rotational IMRT modality operating in ''burst mode''. While it is generally assumed that it will be slower than VMAT, the real limits of operation have not been defined so far. We here present the first systematic study of the technical limits on mARC treatment. The following scenarios are considered: 18, 30, 36 or 45 arclets per rotation (spacing between 20 and 8 ), flat and flattening-filter-free (FFF) energy, arclet width 4 or 2 , from 1 MU/arclet to 1000 MU/plan. All scenarios are irradiated, treatment times are measured and treatment parameters reported. Dose linearity was assessed by point dose measurements of the 18 arclet plans with 1-30 MU per arclet. Minimum treatment times (no MLC movement, few MUs) depend strongly on the number of arclets per rotation (1 minute for 18 arclets to 1:50 min for 45 arclets), and rise linearly with MU/arclets after a given cut-off value depending on scenario, arclet width and available maximum dose rate. MLC movement adds up to 2 minutes of treatment time, but generally less (ca. 45 seconds in realistic plans). The rules by which irradiation parameters are selected by the firmware can be partly discovered. The choice of dose rate is most clearly defined. For the flat 6 MV energy, the highest available dose rate (300 MU/min) is always applied. For FFF 7 MV dose rate is reduced for arclets with few MUs, so that an arclet is irradiated in no less than 0.3 s. Only for the case of 1 MU/arclet can this constraint not be met (the technical limit on the dose rate if 500 MU/min for FFF 7 MV). In this case, dosimetric linearity is reduced. In all other instances, deviations from linearity at low MU remain below 2%. Treatment times of down to 90 seconds are technically achievable for treatment with FFF beams using up to 36 arclets per rotation (arclet spacing every 10 ) for up to 900 MU/plan, comparable to VMAT treatment times. The values provided here are meant to serve as a reference

Identification of a new cell line permissive to porcine reproductive and respiratory syndrome virus infection and replication which is phenotypically distinct from MARC-145 cell line

Directory of Open Access Journals (Sweden)

Provost Chantale

2012-11-01

Full Text Available Abstract Background Airborne transmitted pathogens, such as porcine reproductive and respiratory syndrome virus (PRRSV, need to interact with host cells of the respiratory tract in order to be able to enter and disseminate in the host organism. Pulmonary alveolar macrophages (PAM and MA104 derived monkey kidney MARC-145 cells are known to be permissive to PRRSV infection and replication and are the most studied cells in the literature. More recently, new cell lines developed to study PRRSV have been genetically modified to make them permissive to the virus. The SJPL cell line origin was initially reported to be epithelial cells of the respiratory tract of swine. Thus, the goal of this study was to determine if SJPL cells could support PRRSV infection and replication in vitro. Results The SJPL cell growth was significantly slower than MARC-145 cell growth. The SJPL cells were found to express the CD151 protein but not the CD163 and neither the sialoadhesin PRRSV receptors. During the course of the present study, the SJPL cells have been reported to be of monkey origin. Nevertheless, SJPL cells were found to be permissive to PRRSV infection and replication even if the development of the cytopathic effect was delayed compared to PRRSV-infected MARC-145 cells. Following PRRSV replication, the amount of infectious viral particles produced in SJPL and MARC-145 infected cells was similar. The SJPL cells allowed the replication of several PRRSV North American strains and were almost efficient as MARC-145 cells for virus isolation. Interestingly, PRRSV is 8 to 16 times more sensitive to IFNα antiviral effect in SJPL cell in comparison to that in MARC-145 cells. PRRSV induced an increase in IFNβ mRNA and no up regulation of IFNα mRNA in both infected cell types. In addition, PRRSV induced an up regulation of IFNγ and TNF-α mRNAs only in infected MARC-145 cells. Conclusions In conclusion, the SJPL cells are permissive to PRRSV. In addition, they are

INTRODUCTION: David Sherrington as a mentor of young scientists

Goldbart, Paul M.

2008-08-01

How deeply honoured I am to have the opportunity to express my thoughts at this delightful celebration of David's achievements, so far, in his remarkable career. I have been asked to center my remarks on David's contributions to the mentoring and professional development of scientists early in their careers. This is a topic that I am more than happy to reflect on, because it gives me the opportunity to recall the exciting period I spent as one of David's postgraduate students at Imperial College in the early 1980s. It also gives me the chance to publicly express my gratitude to David for the opportunities he created for me at that time, as well as for the interest and care he has shown in my career and well-being ever since, as we have met up and exchanged news and ideas around the world: in New Mexico and Colorado, in Cancun, Paris and Trieste, at numerous March Meetings of the American Physical Society and, of course in London, Oxford, and my home town, Champaign-Urbana, location of the University of Illinois. I have been a member of David's circle for 25 years now, and I would like to tell you a little about how this came to be. Not because of what this says about me, but, rather, because of what it tells you about David and the rich generosity of his spirit and effort when it comes to supporting the underdog. I was indeed one such underdog—and that's putting it charitably—when I first met David in September of 1982, not long before the academic year was to begin. I had heard about the exciting circle of physical and mathematical ideas swirling around the spin glass question during the previous year, which I had spent at the University of California's Los Angeles campus, through an opportunity kindly arranged, as it happens, by Sam Edwards. But I was eager to return to the UK for postgraduate studies and to work on spin glasses, so I simply showed up at David's Imperial College office, unannounced (if I remember correctly). And with his characteristic

Relationship between time-resolved and non-time-resolved Beer-Lambert law in turbid media.

Nomura, Y; Hazeki, O; Tamura, M

1997-06-01

The time-resolved Beer-Lambert law proposed for oxygen monitoring using pulsed light was extended to the non-time-resolved case in a scattered medium such as living tissues with continuous illumination. The time-resolved Beer-Lambert law was valid for the phantom model and living tissues in the visible and near-infrared regions. The absolute concentration and oxygen saturation of haemoglobin in rat brain and thigh muscle could be determined. The temporal profile of rat brain was reproduced by Monte Carlo simulation. When the temporal profiles of rat brain under different oxygenation states were integrated with time, the absorbance difference was linearly related to changes in the absorption coefficient. When the simulated profiles were integrated, there was a linear relationship within the absorption coefficient which was predicted for fractional inspiratory oxygen concentration from 10 to 100% and, in the case beyond the range of the absorption coefficient, the deviation from linearity was slight. We concluded that an optical pathlength which is independent of changes in the absorption coefficient is a good approximation for near-infrared oxygen monitoring.

Lambert-Beer law in ocean waters: optical properties of water and of dissolved/suspended material, optical energy budgets.

Science.gov (United States)

Stavn, R H

1988-01-15

The role of the Lambert-Beer law in ocean optics is critically examined. The Lambert-Beer law and the three-parameter model of the submarine light field are used to construct an optical energy budget for any hydrosol. It is further applied to the analytical exponential decay coefficient of the light field and used to estimate the optical properties and effects of the dissolved/suspended component in upper ocean layers. The concepts of the empirical exponential decay coefficient (diffuse attenuation coefficient) of the light field and a constant exponential decay coefficient for molecular water are analyzed quantitatively. A constant exponential decay coefficient for water is rejected. The analytical exponential decay coefficient is used to analyze optical gradients in ocean waters.

This paper describes an uncertainty analysis of MARC calculations of the consequences of accidental releases of radioactive materials to atmosphere. A total of 98 parameters describing the transfer of material through the environment to man, the doses received, and the health effects resulting from these doses, was considered. The uncertainties in the numbers of early and late health effects, numbers of people affected by countermeasures, the amounts of food restricted and the economic costs of the accident were estimated. This paper concentrates on the results for early death and fatal cancer for a large hypothetical release from a PWR

A case of Eaton-Lambert syndrome with small cell carcinoma of the lung responding favorably to chemotherapy and radiation was described. The patient, 56-year-old man, began to feel weakness of the upper limbs in 1982 (age 52). His condition deteriorated gradually, followed by weakness of the lower limbs, dysphagia and bilateral ptosis. He was admitted to our hospital in Janualy 1984. We started radiation therapy for the lung mass and his neurological findings improved slightly. In June 1984, he complained of pain in the left elbow accompanied by increased ptosis and weakness in the limbs. The biopsy of left elbow lymphnode revealed the metastasis of intermediate cell type small cell carcinoma of the lung, and the diagnosis of Eaton-Lambert syndrome was confirmed. Metastases were also found at the right parietal bone and cervical lymphnode. We started a combination chemotherapy consisting of ACNU, vincristine, methotrexate and cyclophosphamide, adding prophylactic irradiation to the cranium and metastatic regions. After treatment, the metastases disappeared completely and no abnormal findings were found except for decreased tendon reflexes of the upper limbs. Post-treatment electromyography showed marked reduction of waxing and post-tetanic facilitation. We have intermittently continued a combination chemotherapy for consolidation. The patient is living well 21 months after the distant metastases became apparent, and is showing marked improvement of Eaton-Lambert syndrome through chemotherapy and radiation. We propose that anti-neoplastic treatment is the first choice for the treatment of Eaton-Lambert syndorame associated with small cell carcinoma of long. (J.P.N.).

David de Wied: Eminent scientist and academic leader: A personal note.

Science.gov (United States)

Gispen, Willem Hendrik

2010-01-10

David de Wied was a natural leader with many a talent. He was the director of the Rudolf Magnus Institute at Utrecht University and president of the Royal Netherlands Academy of Arts and Sciences. He coached over 75 Ph.D. students and hosted some 200 foreign scientists who joined him in his multidisciplinary neuropeptide research. Many of them became lifelong friends, frequenting the home of Liedje and David de Wied. Born in Deventer (The Netherlands) on January 12th, 1925, David de Wied's early boyhood first in Deventer and later in Leeuwarden appears to have been no different from that of any other provincial Dutch boys in pre-war Holland. After the war David enrolled at Groningen University to study medicine. Subsequently he specialized in experimental pharmacology. To understand the determination of David de Wied is to understand the drive of a Jewish young man, who during the war, had been forced to go underground and unable to develop in a free and independent manner. Therefore, later in life, time became very precious to him and everything that came across his path had to be taken seriously. In this short sketch of David de Wied I will try to highlight his outstanding scientific accomplishments as well as his personality as both have inspired a generation of young scientists. It is a great honour and a pleasure to be part of this meeting in memory of David de Wied.

The present paper discusses the Lambert-Beer' s law application in the terahertz spectrum, studies the single amino acid tablet sample (glutamine) and two kinds of amino acids mixture tablet (threonine and cystine) under the condition of different concentrations. Absorbance and absorption coefficient was analyzed in the description of the terahertz optical properties of matter. By comparing absorption coefficient and absorbance value of the single component in the vicinity of 1. 72 THz, we verified the material under two kinds of absorption characterization of quantity of THz wave absorption along with the change in the concentration. Using the index of goodness of fit R , it studied the stand or fall of linear relationship between the terahertz absorption quantity of material and concentration under two kinds of representation. This paper analyzes the two components mixture under two kinds of absorption characterization of quantity of terahertz absorption in 0. 3-2. 6 THz. Using the similarity co- efficient and the estimate concentration error as evaluation index, it has been clear that the absorbance of additivity instead of the absorption coefficient should be used during the terahertz spectrum quantitative test, and the Lambert-Beer's law application in the terahertz wave band was further clarified.

A 10-mL graduated cylinder was used to construct a colorimeter to investigate the relationship between absorbance and path length found in the Beer-Lambert law. Light-emitting diodes (LEDs) were used as the light sources and filter monochromators. The experiments were conducted on intensely colored permanganate and tetraamminecopper(II) solutions. The device also was useful for demonstrating the relationship between absorbance and concentration.

ECONO-MARC: A method for assessing the cost of emergency countermeasures after an accident

International Nuclear Information System (INIS)

Clark, M.J.; Dionian, J.

1982-12-01

A method is proposed for assessing the cost of emergency countermeasures taken to reduce radiation exposures after an accidental release of radionuclides into the environment. The cost is estimated as the potential loss of goods and services due to the imposition of countermeasures, measured by a lost contribution to the nation's Gross Domestic Product (GDP). A primary aim in developing such a method is to provide the basis for clear quantitative inputs to difficult decisions in emergency planning; decisions on whether to apply countermeasures, and on the extent to which they should be applied. The method should also provide useful inputs to nuclear siting policy and to safety design assessments. While the method should aid decision-making, it does not measure all the costs; other major costs of nuclear accidents, such as the loss of nuclear plant capacity and the social disruption caused by countermeasures require separate additional assessment. The models in the MARC procedure for accident assessment are under continuing review. This memorandum records the method currently included in ECONO-MARC; additional models and improved procedures will be incorporated, as appropriate, in the future. (author)

Comparison of the MARC and CRAC2 programs for assessing the radiological consequences of accidental releases of radioactive material

CERN Document Server

Hemming, C R; Charles, D; Ostmeyer, R M

1983-01-01

This report describes a comparison of the MARC (Methodology for Assessing Radiological Consequences) and CRAC2 (Calculation of Reactor Accident Consequences, version 2) computer programs for assessing the radiological consequences of accidental releases of radioactive material. A qualitative comparison has been made of the features of the constituent sub-models of the two codes, and potentially the most important differences identified. The influence of these differences has been investigated quantitatively by comparison of the predictions of the two codes in a wide variety of circumstances. Both intermediate quantities and endpoints used as a measure of risk have been compared in order to separate the variables more clearly. The results indicate that, in general, the predictions of MARC and CRAC2 are in good agreement.

In April 1852 in Cape Town, South Africa, Dr David Livingstone, then 39 years of age and yet to commence the explorations of Africa which would bring him to public attention, underwent the surgical procedure of uvulectomy. This article reviews the history of Livingstone's uvulectomy and its indications and outcome, as documented by his own writings. The practice of uvulectomy in indigenous African societies and some contemporary ideas about uvulectomy are also considered in order to try to ascertain why Livingstone elected to undergo this procedure.

Comparison of the foodchain transport models of WASH-1400 and MARC using the accident consequence model UFOMOD

International Nuclear Information System (INIS)

Steinhauer, C.

1985-04-01

Within the frame of the contract with the European Community 'Methods for Assessing the Radiological Impact of Accidents' (CEC-MARIA) comparative accident consequence assessments were performed with the computer code UFOMOD, replacing the currently implemented foodchain transport model of the WASH-1400 study by the dynamic transport model of the MARC methodology. The calculations were based on the release category FK2 of the German Risk Study with meteorological data representing four different regions of the Federal Republic of Germany. The study of seasonal variations was carried out with the MARC data for four representative times of deposition with an agricultural practice adopted in the UK. In this report the differences are presented which are observed in the potential doses due to ingestion, the areas affected by food-bans and the late health effects when using both models and taking the influence of seasonal effects into account.

The modified Beer-Lambert law revisited.

Science.gov (United States)

Kocsis, L; Herman, P; Eke, A

2006-03-07

The modified Beer-Lambert law (MBLL) is the basis of continuous-wave near-infrared tissue spectroscopy (cwNIRS). The differential form of MBLL (dMBLL) states that the change in light attenuation is proportional to the changes in the concentrations of tissue chromophores, mainly oxy- and deoxyhaemoglobin. If attenuation changes are measured at two or more wavelengths, concentration changes can be calculated. The dMBLL is based on two assumptions: (1) the absorption of the tissue changes homogeneously, and (2) the scattering loss is constant. It is known that absorption changes are usually inhomogeneous, and therefore dMBLL underestimates the changes in concentrations (partial volume effect) and every calculated value is influenced by the change in the concentration of other chromophores (cross-talk between chromophores). However, the error introduced by the second assumption (cross-talk of scattering changes) has not been assessed previously. An analytically treatable special case (semi-infinite, homogeneous medium, with optical properties of the cerebral cortex) is utilized here to estimate its order of magnitude. We show that the per cent change of the transport scattering coefficient and that of the absorption coefficient have an approximately equal effect on the changes of attenuation, and a 1% increase in scattering increases the estimated concentration changes by about 0.5 microM.

Sudden cardiac death is the most common cause of unnatural death in football. To prevent and urgently manage sudden cardiac arrest on the football field-of-play, F-MARC (FIFA Medical and Research Centre) has been fully committed to a programme of research, education, standardisation and practical implementation. This strategy has detected football players at medical risk during mandatory precompetition medical assessments. Additionally, FIFA has (1) sponsored internationally accepted guidelines for the interpretation of an athlete's ECG, (2) developed field-of-play-specific protocols for the recognition, response, resuscitation and removal of a football player having sudden cardiac arrest and (3) introduced and distributed the FIFA medical emergency bag which has already resulted in the successful resuscitation of a football player who had a sudden cardiac arrest on the field-of-play. Recently FIFA, in association with the Institute of Sports and Preventive Medicine in Saarbrücken, Germany, established a worldwide Sudden Death Registry with a view to documenting fatal events on the football field-of-play. These activities by F-MARC are testimony to FIFA's continued commitment to minimising sudden cardiac arrest while playing football. Published by the BMJ Publishing Group Limited.

To examine short-term and midterm outcomes after the David and Bentall procedures in patients with an acute type A aortic dissection. Between 2001 and 2017, patients (n = 135) with acute type A aortic dissection underwent an aortic root replacement with either the David (n = 40) or Bentall (n = 95) procedure. Perioperative outcome, reoperation rate, aortic valve function, and long-term survival were evaluated. The median age of the entire cohort was 56 years. Rates of malperfusion (21%), shock (16%), history of renal failure (4%), and extent of surgery were similar between David and Bentall groups. However, the David group was significantly younger (45 versus 61 years) with less hypertension (45% versus 66%), coronary artery disease (0% versus 17%), valvulopathy (5% versus 19%), and prior cardiac surgery (5% versus 21%). Overall operative mortality was 9.6% (David 3% and Bentall 13%). Composite outcome comprising myocardial infarction, stroke, new-onset renal failure, and operative mortality was 18% in the entire cohort (David 5% and Bentall 23%). In the David group, the freedom of moderate aortic insufficiency was 95% at 10 years. The rate of reoperation for pathology of the proximal aorta or aortic valve was 0% and 2% for the David and Bentall groups, respectively. Ten-year Kaplan-Meier survival was 66% (95% confidence interval: 51% to 77%) for the entire cohort, with 98% (95% confidence interval: 84% to 99%) survival in the David group and 57% (95% confidence interval: 42% to 70%) survival in the Bentall group. Both the David and Bentall procedures are appropriate surgical approaches for aortic root replacement in select patients with an acute type A aortic dissection.

Vincent Lambert, Dignity in Dying and the European Court: A Critical Evaluation and the Global Reflections.

Kishore, R R

2016-04-01

In this article I analyse the verdict of the European Court of Human Rights in the Case of Lambert and Others v. France, delivered on 5 June 2015, affirming the Conseil d'État's decision holding that the withdrawal of artificial nutrition and hydration from Vincent Lambert, a French national lying in tetraplegia and persistent vegetative state, was consistent with French domestic law and the European Convention for the Protection of Human Rights and Fundamental Freedoms. In order to make a comparative evaluation I give an account of judicial decisions across the world and find that the European Court's decision is an affirmative pronouncement, in the prevailing milieu of judicial heterogeneity, as it recognizes a person's right to die with dignity in the face of conflicting claims and arguments, by giving supremacy to a person's autonomy and right of self-determination over the deep-rooted religious beliefs and undue paternalistic postures. I conclude that right to die with dignity is a profound area where judge-made law is not the answer. The situation calls for greater consensus and uniformity by evolving suitable legislative strategies.

2014-12-01

Phenolic compounds (benzoic and cinnamic acid derivatives) were determined by high-performance liquid chromatography with multiple wavelength detector (HPLC- -MWD) in grape marc distillates aged in Quercus petraea , Quercus robur and Quercus alba wooden barrels. In addition to colour indices and evaluable polyphenols, all samples were described by sensorial analysis. There were significant differences in the mean concentrations of the majority of phenolic compounds among the samples. Gallic and benzoic acids were the most abundant and samples aged in Q. robur from Galicia (NW of Spain) had the highest concentration of most of the determined phenols. Grape marc distillates aged in Q. robur obtained the highest values of all sensorial attributes, whereas samples aged in Q. petraea and Q. alba obtained similar scores. Principal component analysis accounted for 88.32% of total variance, showing a good separation of aged distillates in terms of phenolic compounds and colour characteristics, according to the species and origin of the oak wood used in the ageing process.

Do Père David's deer lose memories of their ancestral predators?

Directory of Open Access Journals (Sweden)

Chunwang Li

Full Text Available Whether prey retains antipredator behavior after a long period of predator relaxation is an important question in predator-prey evolution. Père David's deer have been raised in enclosures for more than 1200 years and this isolation provides an opportunity to study whether Père David's deer still respond to the cues of their ancestral predators or to novel predators. We played back the sounds of crows (familiar sound and domestic dogs (familiar non-predators, of tigers and wolves (ancestral predators, and of lions (potential naïve predator to Père David's deer in paddocks, and blank sounds to the control group, and videoed the behavior of the deer during the experiment. We also showed life-size photo models of dog, leopard, bear, tiger, wolf, and lion to the deer and video taped their responses after seeing these models. Père David's deer stared at and approached the hidden loudspeaker when they heard the roars of tiger or lion. The deer listened to tiger roars longer, approached to tiger roars more and spent more time staring at the tiger model. The stags were also found to forage less in the trials of tiger roars than that of other sound playbacks. Additionally, it took longer for the deer to restore their normal behavior after they heard tiger roars, which was longer than that after the trial of other sound playbacks. Moreover, the deer were only found to walk away after hearing the sounds of tiger and wolf. Therefore, the tiger was probably the main predator for Père David's deer in ancient time. Our study implies that Père David's deer still retain the memories of the acoustic and visual cues of their ancestral predators in spite of the long term isolation from natural habitat.

To determine the net economic impact of switching from low-osmolar contrast media (LOCM) to iso-osmolar contrast media (IOCM; iodixanol) in patients undergoing inpatient coronary or peripheral angioplasty in the United States (US). A budget impact model (BIM) was developed from a hospital perspective. Nationally representative procedural and contrast media prevalence rates, along with MARCE (major adverse renal cardiovascular event) incidence and episode-related cost data were derived from Premier Hospital Data (October 2014 to September 2015). A previously estimated relative risk reduction in MARCE associated with IOCM usage (9.3%) was applied. The higher cost of IOCM was included when calculating the net impact estimates at the aggregate, hospital type, and per hospital levels. One-way (±25%) and probabilistic sensitivity analyses identified the model's most important inputs. Based on weighted analysis, 513,882 US inpatient angioplasties and 35,610 MARCE cases were estimated annually. Switching to an "IOCM only" strategy from a "LOCM only" strategy increases contrast media cost, but prevents 2,900 MARCE events. The annual budget impact was an estimated saving of $30.71 million, aggregated across all US hospitals, $6,316 per hospital, or $60 per procedure. Net savings were maintained across all univariate sensitivity analyses. While MARCE/event-free cost differential was the most important factor driving total net savings for hospitals in the Northeast and West, procedural volume was important in the Midwest and rural locations. Switching to an "IOCM only" strategy from a "LOCM only" approach yields substantial net global savings to hospitals, both at the national level and within hospital sub-groups. Hospital administrators should maintain awareness of the factors that are likely to be more influential for their hospital and recognize that purchasing on the basis of lower contrast media cost may result in higher overall costs for patients undergoing inpatient

Comments on the Bagger-Lambert theory and multiple M2-branes

International Nuclear Information System (INIS)

Raamsdonk, Mark Van

2008-01-01

We study the SO(8) superconformal theory proposed recently by Bagger and Lambert as a possible worldvolume theory for multiple M2-branes. For their explicit example with gauge group SO(4), we rewrite the theory (originally formulated in terms of a three-algebra) as an ordinary SU(2) x SU(2) gauge theory with bifundamental matter. In this description, the parity invariance of the theory, required for a proper description of M2-branes, is clarified. We describe the subspace of scalar field configurations on which the potential vanishes, correcting an earlier claim. Finally, we point out, for general three-algebras, a difficulty in constructing the required set of superconformal primary operators which should be present in the correct theory describing multiple M2-branes.

Parameters extraction for perovskite solar cells based on Lambert W-function

Directory of Open Access Journals (Sweden)

Ge Junyu

2016-01-01

Full Text Available The behaviors of the solar cells are decided by the device parameters. Thus, it is necessary to extract these parameters to achieve the optimal working condition. Because the five-parameter model of solar cells has the implicit equation of current-voltage relationship, it is difficult to obtain the parameters with conventional methods. In this work, an optimized method is presented to extract device parameters from the actual test data of photovoltaic cell. Based on Lambert W-function, explicit formulation of the model can be deduced. The proposed technique takes suitable method of selecting sample points, which are used to calculate the values of the model parameters. By comparing with the Quasi-Newton method, the results verify accuracy and reliability of this method.

The finite element analysis program MSC Marc/Mentat a first introduction

CERN Document Server

Öchsner, Andreas

2016-01-01

Based on simple examples, this book offers a short introduction to the general-purpose finite element program MSC Marc, a specialized program for non-linear problems (implicit solver) distributed by the MSC Software Corporation, which is commonly used in academia and industry. Today the documentation of all finite element programs includes a variety of step-by-step examples of differing complexity, and in addition, all software companies offer professional workshops on different topics. As such, rather than competing with these, the book focuses on providing simple examples, often single-element problems, which can easily be related to the theory that is discussed in finite element lectures. This makes it an ideal companion book to classical introductory courses on the finite element method.

Merkel cell carcinoma is a rare cutaneous, aggressive tumor. Although it shares many neuroendocrine features with small cell lung carcinoma, it has only occasionally been reported with paraneoplastic neurological syndromes. A healthy 67-year-old man developed acute ataxia, vertigo, and nausea. Subsequently he also developed dysarthria, diplopia, xerostomia, fatigability and progressive anorexia. He underwent a full diagnostic workup and was found to have a high titer of voltage-gated calcium channel antibodies in serum and cerebrospinal fluid, neurophysiological findings compatible with Lambert-Eaton myasthenia and neurological signs compatible with cerebellar degeneration. A positron emission tomography study revealed a hypermetabolic lesion in the axilla, subsequently biopsied and consistent with Merkel cell carcinoma. In most previous reports, neurological symptoms preceded the Merkel cell carcinoma diagnosis, and the primary localization was in lymph nodes. This tumor should be considered in patients with paraneoplastic syndrome, and particularly Lambert-Eaton myasthenia after exclusion of small cell lung carcinoma.

Full Text Available Phenolic compounds (benzoic and cinnamic acid derivatives were determined by high-performance liquid chromatography with multiple wavelength detector (HPLC-MWD in grape marc distillates aged in Quercus petraea, Quercus robur and Quercus alba wooden barrels. In addition to colour indices and evaluable polyphenols, all samples were described by sensorial analysis. There were signifi cant diff erences in the mean concentrations of the majority of phenolic compounds among the samples. Gallic and benzoic acids were the most abundant and samples aged in Q. robur from Galicia (NW of Spain had the highest concentration of most of the determined phenols. Grape marc distillates aged in Q. robur obtained the highest values of all sensorial attributes, whereas samples aged in Q. petraea and Q. alba obtained similar scores. Principal component analysis accounted for 88.32 % of total variance, showing a good separation of aged distillates in terms of phenolic compounds and colour characteristics, according to the species and origin of the oak wood used in the ageing process.

Fall with linear drag and Wien's displacement law: approximate solution and Lambert function

International Nuclear Information System (INIS)

Vial, Alexandre

2012-01-01

We present an approximate solution for the downward time of travel in the case of a mass falling with a linear drag force. We show how a quasi-analytical solution implying the Lambert function can be found. We also show that solving the previous problem is equivalent to the search for Wien's displacement law. These results can be of interest for undergraduate students, as they show that some transcendental equations found in physics may be solved without purely numerical methods. Moreover, as will be seen in the case of Wien's displacement law, solutions based on series expansion can be very accurate even with few terms. (paper)

Technical variations of the David reimplantation valve-sparing aortic root replacement (V-SARR) procedure have been proposed to be advantageous in patients with connective tissue disease, such as the Marfan syndrome (MFS). We report results of a Marfan cohort treated exclusively with the non-modified David I procedure. Forty-eight Marfan patients (25 males, mean age 33 ± 12 years, range 15-62 years) underwent the original variant of the David V-SARR (David I) between 1997 and 2013. Forty-two operations (88%) were performed as elective procedures for aortic root aneurysms and six for acute dissections (12%). Seventeen had aortic regurgitation (AR) grades ≥2+ preoperatively, and 3 had AR >2+. No patients with severe AR (4+) were selected for V-SARR. Three full or hemi-arch replacements were performed. Patients who were operated on using a variation of the David I or David II procedure were excluded. Mean prosthesis size was 28 ± 3 mm (18-30 mm). Mean clinical and echocardiographic follow-up (98% complete) was 3.8 ± 3.7 years with a cumulative follow-up of 178 patient-years. The early mortality rate was 2% (one hospital death). The survival rate was 98% (95% confidence 84-99%) at 4 years and 90% (57-98%) at 8 years with 5 patients at risk at 10 years. The rate of freedom from root or valve reoperation was 97% (79-99%) and 97% (79-99%) at 4 and 8 years, respectively. Only one patient required mechanical aortic valve replacement for progression of AR. Despite potential theoretical drawbacks of the David I V-SARR technique without neo-sinuses or a neo-sinotubular junction, it results in a favourable mid-term outcome in Marfan patients and compares well with reported results of different modifications of David V-SARR. © The Author 2014.

During heating, the optical properties of biological tissues change with the coagulation state. In this study, we propose a technique, which uses these changes to monitor the coagulation process during laser-induced interstitial thermotherapy (LITT). Untreated and coagulated (water bath, temperatures between 35 degrees C and 90 degrees C for 20 minutes.) samples of bovine liver tissue were examined using a Nd:YAG (lambda = 1064 nm) frequency-domain reflectance spectrometer. We determined the time integrated intensities (I(DC)) and the phase shifts (Phi) of the photon density waves after migration through the tissue. From these measured quantities, the time of flight (TOF) of the photons and the absorption coefficients of the samples were derived using the modified microscopic Beer-Lambert law. The absorption coefficients of the liver samples decreased significantly with the temperature in the range between 50 degrees C and 70 degrees C. At the same time, the TOF of the investigated photos was found increased indicating an increased scattering. The coagulation dynamics could be well described using the Arrhenius formalism with the activation energy of 106 kJ/mol and the frequency factor of 1.59 x 10(13)/second. Frequency-domain reflectance spectroscopy in combination with the modified microscopic Beer-Lambert (MBL) is suitable to measure heat induced changes in the absorption and scattering properties of bovine liver in vitro. The technique may be used to monitor the coagulation dynamics during local thermo-coagulation in vivo. Copyright 2005 Wiley-Liss, Inc.

The Lambert-Beer law in time domain form and its application.

Science.gov (United States)

Mosorov, Volodymyr

2017-10-01

The majority of current radioisotope gauges utilize measurements of intensity for a chosen sampling time interval using a detector. Such an approach has several disadvantages: temporal resolution of the gauge is fixed and the accuracy of the measurements is not the same for different count rate. The solution can be the use of a stronger radioactive source, but it will be conflicted with ALARA (As Low As Reasonably Achievable) principle. Therefore, the article presents an alternative approach which is based on modified Lambert-Beer law. The basis of the approach is the registration of time intervals instead of the registration of counts. It allows to increase the temporal resolution of a gauge without the necessity of using a stronger radioactive source and the accuracy of the measurements will not depend on count rate.

Denudation and uplift of the Mawson Escarpment (eastern Lambert Graben, Antarctica) as indicated by apatite fission track data and geomorphological observation

Science.gov (United States)

Lisker, F.; Gibson, H.; Wilson, C.J.; Läufer, A.

2007-01-01

Analysis of three vertical profiles from the southern Mawson Escarpment (Lambert Graben) reveals apatite fission track (AFT) ages ranging from 102±20 to 287±23 Ma and mean lengths of 12.2 to 13.0 μm. Quantitative thermal histories derived from these data consistently indicate onset of slow cooling below 110°C began sometime prior to 300 Ma, and a second stage of rapid cooling from paleotemperatures up to ≤100°C to surface temperatures occurred in the Late Cretaceous – Paleocene. The first cooling phase refers to Carboniferous – Jurassic basement denudation up to 5 km associated with the initial rifting of the Lambert Graben. The presence of the ancient East Antarctic Erosion Surface and rapid Late Cretaceous – Paleocene cooling indicate a second denudational episode during which up to 4.5 km of sedimentary cover rocks were removed, and that is likely linked to the Cretaceous Gondwana breakup between Antarctica and India and subsequent passive continental margin formation.

Fernández-Bayo, Jesús D; Nogales, Rogelio; Romero, Esperanza

2007-05-25

Batch sorption experiments of the insecticide imidacloprid by ten widely different Spanish soils were carried out. The sorption was studied for the active ingredient and its registered formulation Confidor. The temperature effect was studied at 15 degrees C and 25 degrees C. The addition of a vermicompost from spent grape marc (natural and ground), containing 344 g kg(-1) organic carbon, on the sorption of imidacloprid by two selected soils, a sandy loam and a silty clay loam, having organic carbon content of 3.6 g kg(-1) and 9.3 g kg(-1), respectively, was evaluated. Prior to the addition of this vermicompost, desorption isotherms with both selected soils, were also performed. The apparent hysteresis index (AHI) parameter was used to quantify sorption-desorption hysteresis. Sorption coefficients, K(d) and K(f), for the active ingredient and Confidor(R) in the different soils were similar. Sorption decreased with increasing temperature, this fact has special interest in greenhouse systems. A significant correlation (R(2)=0.965; Pcharacteristics of soils could contribute to the retention capacity as well. The spent grape marc vermicompost was an effective sorbent of this insecticide (K(f)=149). The sorption of imidacloprid increased significantly in soils amended with this vermicompost. The most pronounced effect was found in the sandy loam soil with low OC content, where the addition of 5% and 10% of vermicompost increased K(f) values by 8- and 15-fold, respectively. Soil desorption of imidacloprid was slower for the soil with the higher OC and clay content.

Full Text Available Food industry produces significant amount of waste that represents a problem for the sector. However, by-products are also promising sources of compounds which may be reused for their nutritional properties. The aim of this work is to exploit wine-making by-products, obtaining an extract by ultrasound-assisted extraction only using water as solvent. The characteristics of spaghetti enriched with grape marc were assessed and compared to control samples. In particular, total phenolic and flavonoids contents, the antioxidant activity, the cooking quality, and the sensory acceptability were evaluated at various steps of pasta production. The enriched spaghetti showed higher total phenolic and flavonoids contents and higher antioxidant activity than the control pasta. In addition, low cooking losses were found. In terms of sensory properties fortified pasta is acceptable as the traditional product, thus demonstrating that it is possible to exploit food waste to better satisfy consumer demand for healthy food products in a more sustainable perspective.

Lambert W-function based exact representation for double diode model of solar cells: Comparison on fitness and parameter extraction

International Nuclear Information System (INIS)

Gao, Xiankun; Cui, Yan; Hu, Jianjun; Xu, Guangyin; Yu, Yongchang

2016-01-01

Highlights: • Lambert W-function based exact representation (LBER) is presented for double diode model (DDM). • Fitness difference between LBER and DDM is verified by reported parameter values. • The proposed LBER can better represent the I–V and P–V characteristics of solar cells. • Parameter extraction difference between LBER and DDM is validated by two algorithms. • The parameter values extracted from LBER are more accurate than those from DDM. - Abstract: Accurate modeling and parameter extraction of solar cells play an important role in the simulation and optimization of PV systems. This paper presents a Lambert W-function based exact representation (LBER) for traditional double diode model (DDM) of solar cells, and then compares their fitness and parameter extraction performance. Unlike existing works, the proposed LBER is rigorously derived from DDM, and in LBER the coefficients of Lambert W-function are not extra parameters to be extracted or arbitrary scalars but the vectors of terminal voltage and current of solar cells. The fitness difference between LBER and DDM is objectively validated by the reported parameter values and experimental I–V data of a solar cell and four solar modules from different technologies. The comparison results indicate that under the same parameter values, the proposed LBER can better represent the I–V and P–V characteristics of solar cells and provide a closer representation to actual maximum power points of all module types. Two different algorithms are used to compare the parameter extraction performance of LBER and DDM. One is our restart-based bound constrained Nelder-Mead (rbcNM) algorithm implemented in Matlab, and the other is the reported R_c_r-IJADE algorithm executed in Visual Studio. The comparison results reveal that, the parameter values extracted from LBER using two algorithms are always more accurate and robust than those from DDM despite more time consuming. As an improved version of DDM, the

Hypotension due to Chemotherapy in a Patient with Small Cell Lung Cancer and Lambert-Eaton Myasthenic Syndrome Undergoing Hemodialysis: A First Case Report

Directory of Open Access Journals (Sweden)

Taiji Kuwata

2012-01-01

Full Text Available We present the first case of small cell lung cancer with Lambert-Eaton myasthenic syndrome during hemodialysis (HD. A 72-year-old male patient receiving HD experienced progressive muscle weakness. He was diagnosed with small cell lung cancer with Lambert-Eaton myasthenic syndrome due to an increased serum level of anti-voltage-gated calcium channel antibody and aspiration cytology on endobronchial ultrasonography for the swelling of a subcarinal lymph node. He received chemotherapy consisting of carboplatin (300 mg/m2 and etoposide (50 mg/m2, to which he had a partial response. However, the second therapy course could not be administered because of the unexpected development of severe hematological adverse events, which also prevented him from undergoing further HD. This case indicates that caution should be taken when using chemotherapy for such patients because of hypotension due to chemotherapy, with which it is impossible to undergo HD.

Anachronism in the writing of History: ¿Error or Possibility? Some reflections about the concept of time in Carlo Ginzburg, Marc Bloch and Georges Didi-Huberman

Directory of Open Access Journals (Sweden)

Maria Eugenia Chaves Maldonado

2016-01-01

Full Text Available In his unfinished and posthumously published book Apologie pour l’histoire, Marc Bloch bestowed on future historians a seminal legacy of critical reflections on the concept of time as the object of historical analysis. During the last decades, the concept of time in History has experienced a renewed interest by professional historians, in particular in reference to the category of anachronism. The Italian historian Carlo Ginzburg and the French art historian Georges Didi-Huberman are among those engaged in this debate. This article offers a reading of two works by these historians with the purpose of underlying the fundamental influence that Marc Bloch’s ideas on time had in Ginzburg and Didi-Hubermans’ critical interventions.

Atomistic simulations of ultra-short pulse laser ablation of aluminum: validity of the Lambert-Beer law

2018-05-01

Based on hybrid molecular dynamics/two-temperature simulations, we study the validity of the application of Lambert-Beer's law, which is conveniently used in various modeling approaches of ultra-short pulse laser ablation of metals. The method is compared to a more rigorous treatment, which involves solving the Helmholtz wave equation for different pulse durations ranging from 100 fs to 5 ps and a wavelength of 800 nm. Our simulations show a growing agreement with increasing pulse durations, and we provide appropriate optical parameters for all investigated pulse durations.

Advanced finite element simulation with MSC Marc application of user subroutines

CERN Document Server

Javanbakht, Zia

2017-01-01

This book offers an in-depth insight into the general-purpose finite element program MSC Marc, which is distributed by MSC Software Corporation. It is a specialized program for nonlinear problems (implicit solver) which is common in academia and industry. The primary goal of this book is to provide a comprehensive introduction to a special feature of this software: the user can write user-subroutines in the programming language Fortran, which is the language of all classical finite element packages. This subroutine feature allows the user to replace certain modules of the core code and to implement new features such as constitutive laws or new elements. Thus, the functionality of commercial codes (‘black box’) can easily be extended by linking user written code to the main core of the program. This feature allows to take advantage of a commercial software package with the flexibility of a ‘semi-open’ code. .

David Lukens Reasoner, former head of NASA's Ionospheric Physics branch, died on April 21, 1992. Reasoner was born July 1, 1941. He worked tirelessly to expand NASA's Space Physics Division, bringing his deep experience and personal expertise to bear on the challenges of growth.During the magical period of the late 1950s and early 1960s when America turned its eyes toward space and the Moon, David Lukens Reasoner journeyed north from the nearby Texas town of Dickinson to Rice University with an idea of getting involved in exploring the frontiers of space. He pursued a course of study in electrical engineering and received a bachelor's degree in 1963 and a master's degree in 1964. In the early 1960s, the Space Science Department at Rice was formed, and President John Kennedy visited to say that America chose to go to space not because it is easy but because it is hard and because it would require the very best talents of our nation to succeed. Dave Reasoner was one of those talented people. His excellence in electrical engineering and physics, combined with his natural abilities in the laboratory, suited him ideally for building the machines of space. As a student, he built sounding rocket payloads and multiple instruments for satellites and experiment packages that were placed on the Moon by the Apollo astronauts. He completed his doctoral degree in space science in 1968. It was in these early thrilling days of space exploration that I first met Dave, beginning a friendship and collegial relationship that was to last 27 years.

David Bowie’s Influence on JoJo’s Bizarre Adventure

Francesco-Alessio Ursini

2017-03-01

Full Text Available This article analyses the influence of David Bowie’s work in JoJo’s Bizarre Adventure, a manga known for its wealth of references to western popular culture. It is argued that David Bowie’s cultural reception can be attested via the presence of three narrative themes featuring in this manga series. The first theme is the exploration of diverse genres and an innovative, genre-defying attitude. The second theme is the use of avant-garde, flamboyant and gender-ambiguous aesthetics for its fictional characters. The third theme is a self-reflexive approach to the creation of fictional characters, intended as an awareness of the temporary, transient nature of their role as reluctant heroes in their own stories.

DAVID Knowledgebase: a gene-centered database integrating heterogeneous gene annotation resources to facilitate high-throughput gene functional analysis

Directory of Open Access Journals (Sweden)

Baseler Michael W

2007-11-01

Full Text Available Abstract Background Due to the complex and distributed nature of biological research, our current biological knowledge is spread over many redundant annotation databases maintained by many independent groups. Analysts usually need to visit many of these bioinformatics databases in order to integrate comprehensive annotation information for their genes, which becomes one of the bottlenecks, particularly for the analytic task associated with a large gene list. Thus, a highly centralized and ready-to-use gene-annotation knowledgebase is in demand for high throughput gene functional analysis. Description The DAVID Knowledgebase is built around the DAVID Gene Concept, a single-linkage method to agglomerate tens of millions of gene/protein identifiers from a variety of public genomic resources into DAVID gene clusters. The grouping of such identifiers improves the cross-reference capability, particularly across NCBI and UniProt systems, enabling more than 40 publicly available functional annotation sources to be comprehensively integrated and centralized by the DAVID gene clusters. The simple, pair-wise, text format files which make up the DAVID Knowledgebase are freely downloadable for various data analysis uses. In addition, a well organized web interface allows users to query different types of heterogeneous annotations in a high-throughput manner. Conclusion The DAVID Knowledgebase is designed to facilitate high throughput gene functional analysis. For a given gene list, it not only provides the quick accessibility to a wide range of heterogeneous annotation data in a centralized location, but also enriches the level of biological information for an individual gene. Moreover, the entire DAVID Knowledgebase is freely downloadable or searchable at http://david.abcc.ncifcrf.gov/knowledgebase/.

This study aimed at using grape marc for the growth of lactic acid bacteria and bifidobacteria with the perspective of producing a functional ingredient having antioxidant activity. Lactobacillus plantarum 12A and PU1, Lactobacillus paracasei 14A, and Bifidobacterium breve 15A showed the ability to grow on grape marc (GM) based media. The highest bacterial cell density (>9.0 CFU/g) was found in GM added of 1% of glucose (GMG). Compared to un-inoculated and incubated control fermented GMG showed a decrease of carbohydrates and citric acid together with an increase of lactic acid. The content of several free amino acids and phenol compounds differed between samples. Based on the survival under simulated gastro-intestinal conditions, GMG was a suitable carrier of lactic acid bacteria and bifidobacteria strains. Compared to the control, cell-free supernatant (CFS) of fermented GMG exhibited a marked antioxidant activity in vitro. The increased antioxidant activity was confirmed using Caco-2 cell line after inducing oxidative stress, and determining cell viability and radical scavenging activity through MTT and DCFH-DA assays, respectively. Supporting these founding, the SOD-2 gene expression of Caco-2 cells also showed a lowest pro-oxidant effect induced by the four CFS of GMG fermented by lactic acid bacteria and bifidobacteria.

MSC Software is leading developer of CAE-software in the world, so behaviour of fuel elements modeling with MSC.MARC use is of great practical importance. Behaviour of fuel elements usually is modeled in the elastic-viscous-plastic statement with account on fuel swelling during irradiation. For container type fuel elements contact interaction between fuel pellets and cladding or other parts of fuel element in top and bottom plugs must be in account. Results of simulated behaviour of various type fuel elements - container type fuel elements for PWR and RBMK reactors, dispersion type fuel elements for research reactors are presented. (authors)

Morphological characterization of diesel soot agglomerates based on the Beer–Lambert law

International Nuclear Information System (INIS)

Lapuerta, Magín; Expósito, Juan José; Martos, Francisco J

2013-01-01

A new method is proposed for the determination of the number of primary particles composing soot agglomerates emitted from diesel engines as well as their individual fractal dimension. The method is based on the Beer–Lambert law and it is applied to micro-photographs taken in high resolution transmission electron microscopy. Differences in the grey levels of the images lead to a more accurate estimation of the geometry of the agglomerate (in this case radius of gyration) than other methods based exclusively on the planar projections of the agglomerates. The method was validated by applying it to different images of the same agglomerate observed from different angles of incidence, and proving that the effect of the angle of incidence is minor, contrary to other methods. Finally, the comparisons with other methods showed that the size, number of primary particles and fractal dimension (the latter depending on the particle size) are usually underestimated when only planar projections of the agglomerates are considered.

Presents an obituary for David L. Rosenhan (1929-2012). A distinguished psychologist and professor emeritus at Stanford University, Rosenhan died February 6, 2012, at the age of 82, after a long illness. Born in Jersey City, New Jersey, on November 22, 1929, he received a bachelor's degree in mathematics (1951) from Yeshiva College and a master's degree in economics (1953) and a doctorate in psychology (1958) from Columbia University. A professor of law and of psychology at Stanford University from 1971 until his retirement in 1998, Rosenhan was a pioneer in applying psychological methods to the practice of law, including the examination of expert witnesses, jury selection, and jury deliberation. A former president of the American Psychology-Law Society and of the American Board of Forensic Psychology, Rosenhan was a fellow of the American Association for the Advancement of Science, of the American Psychological Association, and of the American Psychological Society. Before joining the Stanford Law School faculty, he was a member of the faculties of Swarthmore College, Princeton University, Haverford College, and the University of Pennsylvania. He also served as a research psychologist at the Educational Testing Service. As generations of Stanford students can attest, David Rosenhan was a spellbinding lecturer who managed to convey the sense that he was speaking to each individual, no matter how large the group. To his graduate students, he was consistently encouraging and optimistic, always ready to share a joke or story, and gently encouraging of their creativity and progressive independence as researchers. The lessons he cared most about offering, in the classroom as in his research, were about human dignity and the need to confront abuse of power and human frailties. © 2013 APA, all rights reserved.

Antibiotic-Mediated Inhibition of Porcine Reproductive and Respiratory Syndrome Virus (PRRSV Infection: A Novel Quinolone Function Which Potentiates the Antiviral Cytokine Response in MARC-145 Cells and Pig Macrophages

Directory of Open Access Journals (Sweden)

William A. Cafruny

2008-01-01

Full Text Available Porcine reproductive and respiratory syndrome virus (PRRSV is an economically significant agent for which there currently are no effective treatments. Development of antiviral agents for PRRSV as well as many other viruses has been limited by toxicity of known antiviral compounds. In contrast, antibiotics for non-virus microbial infections have been widely useful, in part because of their acceptable toxicity in animals. We report here the discovery that the quinolonecontaining compound Plasmocin™, as well as the quinolones nalidixic acid and ciprofloxacin, have potent anti-PRRSV activity in vitro. PRRSV replication was inhibited by these antibiotics in both cultured MARC-145 cells and cultured primary alveolar porcine macrophages (PAMs. Furthermore, sub-optimal concentrations of nalidixic acid synergized with antiviral cytokines (AK-2 or IFN-γ to quantitatively and qualitatively inhibit PRRSV replication in MARC-145 cells or PAMs. The antiviral activity of Plasmocin and nalidixic acid correlated with reduced actin expression in MARC-145 cells. Replication of the related lactate dehydrogenase-elevating virus (LDV was also inhibited in primary mouse macrophages by Plasmocin. These results are significant to the development of antiviral strategies with potentially reduced toxicity, and provide a model system to better understand regulation of arterivirus replication.

The Will to Touch: David Copperfield’s Hand

Directory of Open Access Journals (Sweden)

Pamela K. Gilbert

2014-10-01

Full Text Available In the nineteenth century, touch was considered to be a more privileged sense than has been generally noted, and the hand was pre-eminently the site of active touching. The hand comes newly to rival the face in descriptive significance in mid-nineteenth-century fiction, and reflects contemporary notions of the role of touch in the exercise of the will and the development of the sensorium. This article explores medical and philosophical understandings of embodied touch within the period, and examines why the hand emerged as a focal point for scientific, poetic, and popular discussion. Such scientists as Charles Bell, Herbert Spencer, and Alexander Bain tend to work within two paradigms: the hand as a site of sensory input that forms a conduit between inner and outer worlds, and the hand as an instrument of the will. The article explores Dickens's use of these ideas about touch and development in his 1850 'Bildungsroman', 'David Copperfield'. David struggles to establish his proper status as a middle-class male, in part by learning to use his hands to impose his own will and to resist the dominance of inappropriate others through touch.

2017-01-01

Panax ginseng marc is produced from fresh ginseng roots during processing and is generally treated as industrial waste. The primary aim of this study was to improve its utilization in the dairy industry as a potential high-value resource. Yogurt was prepared from 11% skim milk powder, 0.1% pectin, 10% sucrose, and ginseng marc ethanol extract (GME, 0.5% and 1.0%) in milk, and was inoculated with a 0.02% yogurt culture (Lactobacillus acidophilus, Bifidobacterium longum, and Streptococcus thermophilus). After fermentation at 40°C for 6-8 h, the physicochemical properties of samples were analyzed by the AOAC, Kjeldahl, and Soxhlet methods. Sensory evaluation was performed based on consumer acceptability scores with a 7-point scale, and antimicrobial effects were measured by the agar plate method. The moisture, crude protein, crude fat, and ash contents of yogurt supplemented with 1% GME were 85.06±0.06%, 4.41±0.01%, 4.30±0.05%, and 0.81±0.03%, respectively, with no significant changes noted from those of yogurt without GME (control), except for an increase in the crude fat content. The sensory scores of color, flavor, texture, overall taste, and overall acceptance of yogurt supplemented with below 1% GME did not differ significantly (pyogurt. In addition, the growths of Staphylococcus aureus, Bacillus cereus, Listeria monocytogenes, Escherichia coli, and Enterobacter sakazakii were inhibited during fermentation and storage. These results suggest that GME could be used in dairy products as a supplement and in the food industry as an antimicrobial material. PMID:29147103

Combining linear polarization spectroscopy and the Representative Layer Theory to measure the Beer-Lambert law absorbance of highly scattering materials.

Science.gov (United States)

Gobrecht, Alexia; Bendoula, Ryad; Roger, Jean-Michel; Bellon-Maurel, Véronique

2015-01-01

Visible and Near Infrared (Vis-NIR) Spectroscopy is a powerful non destructive analytical method used to analyze major compounds in bulk materials and products and requiring no sample preparation. It is widely used in routine analysis and also in-line in industries, in-vivo with biomedical applications or in-field for agricultural and environmental applications. However, highly scattering samples subvert Beer-Lambert law's linear relationship between spectral absorbance and the concentrations. Instead of spectral pre-processing, which is commonly used by Vis-NIR spectroscopists to mitigate the scattering effect, we put forward an optical method, based on Polarized Light Spectroscopy to improve the absorbance signal measurement on highly scattering samples. This method selects part of the signal which is less impacted by scattering. The resulted signal is combined in the Absorption/Remission function defined in Dahm's Representative Layer Theory to compute an absorbance signal fulfilling Beer-Lambert's law, i.e. being linearly related to concentration of the chemicals composing the sample. The underpinning theories have been experimentally evaluated on scattering samples in liquid form and in powdered form. The method produced more accurate spectra and the Pearson's coefficient assessing the linearity between the absorbance spectra and the concentration of the added dye improved from 0.94 to 0.99 for liquid samples and 0.84-0.97 for powdered samples.

Full Text Available The groundbreaking English language translation of Tirant lo Blanc by New York poet and academic David Rosenthal remains dominant three decades after its initial, and celebrated, release. Rosenthal’s controversially fluid and concise rendering of the Valencian classic survived a serious challenge 20 years ago by a more literal version from a well-meaning amateur translator and journeyman academic backed by a leading U.S.-based Catalan scholar. The article reviews the controversy and compares the two versions, adding comments from some of the key critics.

DAVID: A new video motion sensor for outdoor perimeter applications

International Nuclear Information System (INIS)

Alexander, J.C.

1986-01-01

To be effective, a perimeter intrusion detection system must comprise both sensor and rapid assessment components. The use of closed circuit television (CCTV) to provide the rapid assessment capability, makes possible the use of video motion detection (VMD) processing as a system sensor component. Despite it's conceptual appeal, video motion detection has not been widely used in outdoor perimeter systems because of an inability to discriminate between genuine intrusions and numerous environmental effects such as cloud shadows, wind motion, reflections, precipitation, etc. The result has been an unacceptably high false alarm rate and operator work-load. DAVID (Digital Automatic Video Intrusion Detector) utilizes new digital signal processing techniques to achieve a dramatic improvement in discrimination performance thereby making video motion detection practical for outdoor applications. This paper begins with a discussion of the key considerations in implementing an outdoor video intrusion detection system, followed by a description of the DAVID design in light of these considerations

Eisenman, R; Girdner, E J; Burroughs, R G; Routman, M

1993-01-01

The attitudes of 211 students at a university in Mississippi were investigated both before and after seeing the Public Broadcasting Film Who Is David Duke? The film provided evidence of Duke's current racism, anti-Semitism, and pro-Nazi leanings. In a previous study with university students in Louisiana, the majority did not change their attitudes after watching the film (Eisenman, 1993). However, in the present study, students' attitudes showed change in an anti-Duke direction. The findings are discussed and reasons given for the differences between the two samples, and for the popularity of Duke, a former leader of the Ku Klux Klan.

Multiple scattering corrections to the Beer-Lambert law. 2: Detector with a variable field of view.

Science.gov (United States)

Zardecki, A; Tam, W G

1982-07-01

The multiple scattering corrections to the Beer-Lambert law in the case of a detector with a variable field of view are analyzed. We introduce transmission functions relating the received radiant power to reference power levels relevant to two different experimental situations. In the first case, the transmission function relates the received power to a reference power level appropriate to a nonattenuating medium. In the second case, the reference power level is established by bringing the receiver to the close-up position with respect to the source. To examine the effect of the variation of the detector field of view the behavior of the gain factor is studied. Numerical results modeling the laser beam propagation in fog, cloud, and rain are presented.

Phototransduction early steps model based on Beer-Lambert optical law.

Science.gov (United States)

Salido, Ezequiel M; Servalli, Leonardo N; Gomez, Juan Carlos; Verrastro, Claudio

2017-02-01

The amount of available rhodopsin on the photoreceptor outer segment and its change over time is not considered in classic models of phototransduction. Thus, those models do not take into account the absorptance variation of the outer segment under different brightness conditions. The relationship between the light absorbed by a medium and its absorptance is well described by the Beer-Lambert law. This newly proposed model implements the absorptance variation phenomenon in a set of equations that admit photons per second as input and results in active rhodopsins per second as output. This study compares the classic model of phototransduction developed by Forti et al. (1989) to this new model by using different light stimuli to measure active rhodopsin and photocurrent. The results show a linear relationship between light stimulus and active rhodopsin in the Forti model and an exponential saturation in the new model. Further, photocurrent values have shown that the new model behaves equivalently to the experimental and theoretical data as published by Forti in dark-adapted rods, but fits significantly better under light-adapted conditions. The new model successfully introduced a physics optical law to the standard model of phototransduction adding a new processing layer that had not been mathematically implemented before. In addition, it describes the physiological concept of saturation and delivers outputs in concordance to input magnitudes. Copyright © 2017 Elsevier Ltd. All rights reserved.

Constructing history on television: Marc Ferro and newsreels in Histoire Parallèle

Sheila Schvarzman

2014-01-01

Full Text Available In 1989, when Europe was being transformed after the fall of the Berlin Wall and the expansion of satellite communications, La Sept, a Franco-German TV channel, came into being. Histoire Paralèlle, a TV show hosted by Marc Ferro with newsreels shown in both countries, 50 years before, became the most watched program of the station, comparing the images the ways in which German and French started the war, as it should be seen and experienced by their fellow citizens. The program became a socialized process of understanding and historical rewriting, besides standing before the conflict between memory and history, a question that guided the historiography of the 1990s. This article analyzes Histoire Paralèlle, examining the relationship that it established with the historiography and filmic production of the historian. Therefore, its theoretical assumptions are re-discussed and historicized in the context of Ferro's works and through the analysis of three of his programs.

Full Text Available In April 1973 David Bowie released 'Aladdin Sane'. The cover of 'Aladdin Sane' features an iconic image of David Bowie, a close-up shot of the artist with brightly colored orange hair and asymmetrical lightning bolt make-up on the right side of his face. This article argues that the cover image for 'Aladdin Sane' uses the Close-Up Eye Asymmetry (CUE-A pictorial device (i.e., close-up view of David Bowie, asymmetrical make-up around his eye and that CUE-A was adopted into Comic Book Visual Language by first providing evidence that CUE-A is used in comic book art. A link is then established between comic book art and music album art by showing that: (1 David Bowie was familiar with Comic Book Visual Language and could make a contribution to the language, and (2 comic book artists are influenced by music album art. I then make a case that the adoption of CUE-A into Comic Book Visual Language was specifically due to the cover image for 'Aladdin Sane' by analyzing: (1 the use of CUE-A by influential artists in the 1990s and (2 the different rates of adoption of CUE-A for the depiction of established versus newer comic book characters.

Aortic valve-sparing David procedure has gained broad acceptance. However, few long-term results have been published. We present our results. More than 450 David procedures have been performed in our institution so far. Of these, 126 patients were operated between July 1993 and December 2000. Median age was 57 (8-83) years and 46 (36.5%) were female. As many as 26 (20.6%) had Marfan syndrome, 21 (16.7%) had acute aortic dissection type A (AADA) and 67 (53.2%) had additional procedures. There were six (4.8%) deaths in 30 post-operative period (POD), four of whom had AADA. In the follow-up, there were 32 (25.4%) late deaths, 11 (34.4%) of these were caused by cardiac or underlying disease or op-related. As many as 15 (11.9%) patients were re-operated; six (40%) were Marfan patients and two (13.3%) had early endocarditis. Follow-up echocardiography of 76 (60.3%) event-free patients showed valve insufficiency (AI)≤AI I° in 68 (89.5%) and grade II in 7 (9.2%) patients. Leaflet degeneration due to proposed leaflet contact with the straight Dacron graft was not observed. A total of 36 (47.4%) patients were in New York Heart Association (NYHA) class I, 33 (43.4%) in NYHA II, and five (6.6%) were in class III. During the entire follow-up of 790 patient-years, there was no stroke or major bleeding. Survival at 1, 5 and 10 years was 93%, 85% and 70%, respectively. Freedom from valve replacement at 1, 5 and 10 years was 96%, 91% and 87%, respectively. Regardless of the underlying pathology, valve-sparing David I procedure has acceptable long-term results. Valve-related complications such as stroke or major bleeding is exceedingly low.

A polychromatic adaption of the Beer-Lambert model for spectral decomposition

Science.gov (United States)

Sellerer, Thorsten; Ehn, Sebastian; Mechlem, Korbinian; Pfeiffer, Franz; Herzen, Julia; Noël, Peter B.

2017-03-01

We present a semi-empirical forward-model for spectral photon-counting CT which is fully compatible with state-of-the-art maximum-likelihood estimators (MLE) for basis material line integrals. The model relies on a minimum calibration effort to make the method applicable in routine clinical set-ups with the need for periodic re-calibration. In this work we present an experimental verifcation of our proposed method. The proposed method uses an adapted Beer-Lambert model, describing the energy dependent attenuation of a polychromatic x-ray spectrum using additional exponential terms. In an experimental dual-energy photon-counting CT setup based on a CdTe detector, the model demonstrates an accurate prediction of the registered counts for an attenuated polychromatic spectrum. Thereby deviations between model and measurement data lie within the Poisson statistical limit of the performed acquisitions, providing an effectively unbiased forward-model. The experimental data also shows that the model is capable of handling possible spectral distortions introduced by the photon-counting detector and CdTe sensor. The simplicity and high accuracy of the proposed model provides a viable forward-model for MLE-based spectral decomposition methods without the need of costly and time-consuming characterization of the system response.

Modeling systematic errors: polychromatic sources of Beer-Lambert deviations in HPLC/UV and nonchromatographic spectrophotometric assays.

Science.gov (United States)

Galli, C

2001-07-01

It is well established that the use of polychromatic radiation in spectrophotometric assays leads to excursions from the Beer-Lambert limit. This Note models the resulting systematic error as a function of assay spectral width, slope of molecular extinction coefficient, and analyte concentration. The theoretical calculations are compared with recent experimental results; a parameter is introduced which can be used to estimate the magnitude of the systematic error in both chromatographic and nonchromatographic spectrophotometric assays. It is important to realize that the polychromatic radiation employed in common laboratory equipment can yield assay errors up to approximately 4%, even at absorption levels generally considered 'safe' (i.e. absorption <1). Thus careful consideration of instrumental spectral width, analyte concentration, and slope of molecular extinction coefficient is required to ensure robust analytical methods.

Modern 3D scanning technologies allow to reconstruct 3D digital representations of Cultural Heritage artifacts in a semi-automatic way, characterized by very high accuracy and wealth of details. The availability of an accurate digital representation opens several possibilities of utilization to experts (restorers, archivists, museum curators), or to ordinary people (students, museum visitors). 3D scanned data are commonly used for the production of animations, interactive visualizations, or virtual reality applications. A much more exciting opportunity is to use these data in the restoration of Cultural Heritage artworks. The integration between 3D graphic and restoration represents an open research field where many new supporting tools are required; the David restoration project has given several starting points and guidelines to the definition and development of innovative solutions. Digital 3D models can be used in two different but not subsidiary modes: as an instrument for the execution of specific investigations and as a supporting media for the archival and integration of all the restoration-related information, gathered with the different studies and analysis performed on the artwork. In this paper we present some recent work done in the framework of the Michelangelo's David restoration project. A 3D model of the David was reconstructed by the Digital Michelangelo Project, using laser-based 3D scanning technology. We have developed some tools to make those data accessible and useful in the restoration. Preliminary results are reported here together with some directions for further research.

1992-01-01

SeaMARC IA sidescan sonar images of the distal reaches of a depositional lobe on the Mississippi Fan show that channelized rather than unconfined transport was the dominant transport mechanism for coarse-grained sediment during the formation of this part of the deep-sea fan. Overbank sheet flow of sands was not an important process in the transport and deposition of the sandy and silty sediment found on this fan. The dendritic distributary pattern and the high order of splaying of the channels, only one of which appears to have been active at a time, suggest that coarse-grained deposits on this fan are laterally discontinuous.

Eurydice at Euston?: Walter Benjamin and Marc Augé Go Underground

Directory of Open Access Journals (Sweden)

Graeme Gilloch

2014-01-01

Full Text Available Taking as its point of departure Walter Benjamin’s repeatedly unsuccessful attempt to give spatial form to his past, this paper suggests that it is perhaps the contemporary French anthropologist, Marc Augé, who provides the most appropriate envisioning of a ‘map of memories’ in his brief writings on the Parisian métro system. For Augé, the labyrinthine subway network constitutes nothing less than a ‘memory machine’ in which lines and station names serve as mnemonics, recalling long-forgotten childhood encounters and experiences. Mirroring the cityscape above, places themselves unexplored, unknown, the serried toponyms of the métro become an incantation summoning forth the shades of the past. As Augé points out, those stations that provide opportunities to change lines are felicitously termed ‘correspondences’, a Baudelairean term that fascinated Benjamin and informed his key historiographical notion of the ‘dialectical image,’ the intersection and mutual illumination of past and present moments. For me, Augé’s highly suggestive reflections bring to mind my own memories of a London childhood around 1970. Looking at the London underground map today, I cannot but see the sites of many past meetings and partings, dots connected by lines forming complex figures, constellations of memory.

2013-01-01

This chapter has two emphases, one is about the men who influenced the visual representations that David Ferrier (1843-1928) used to illustrate his work on localization of brain functions during the years 1873-1875, namely, Alexander Ecker, John C. Galton, and Ernest Waterlow, and the other is about the nature of medical representations and of Ferrier's illustrations in particular. Medical illustrations are characterized either as pictures, line drawings, or brain maps. Ferrier's illustrations will be shown to be increasingly sophisticated brain maps that contrast with early nineteenth-century standards of medical illustrations, as exemplified by John Bell (1763-1829). © 2013 Elsevier B.V.

Full Text Available The purpose of this study is to understand which bibliographic data are the core elements of the user’s queries? What users’ viewpoints about resource descriptions using different metadata standards? What kinds of value-added items are the users’ favorite when they conduct a bibliographic search? What are users’ viewpoints about bibliographic records integrated with the Digital Archival and Institutional Repository resources through metadata interoperability methods? This research adopted experiments, observation and interviews. The sample subjects are drawn from 14 students of The Graduate Institute of Library and Information Science and College of Agriculture and Natural Resources. First of all, the researcher displayed the bibliographic records using original MARC from the library. Secondly, users compared the images of OPAC from the library with the format of DC and MODS transformed through the MarcEdit software. Additionally, the researcher conducted interviews to understand users’ viewpoints about using three metadata schemas to describe the same book. Finally, the researcher asked the degree of users’ satisfaction about using bibliographic records alone and bibliographic records integrated with the Digital Archival and Institutional Repository resources. The findings suggest that libraries could provide more value-added and comprehensive services of bibliographic records and information retrieval, in order for all kinds of resources to be fully utilized, which helps to meet the users’ information needs.

The development of technologies that combine the advantages of nanomedicine with natural medicine represents a versatile approach to improve the safety and efficacy of drugs. Glycyrrhizinic acid (GA) is a natural compound that has a wide range of biological activities for the treatment of diseases. To establish a safe nanotransport system for this drug, two different nanoparticles with glycyrrhizinic acid, solid lipid nanoparticles (SLN-GA) and polymeric nanoparticles (PNPS-GA) were elaborated to obtain nanostructure sizes between 200 and 300 nm. The nanoparticles were evaluated at concentrations of 1.25-100 μl/ml using the MARC-145 cell line to determine the effects on cell morphology, cellular structure (actin filaments) and cell viability (mitochondrial and lysosomal) at 24 and 72 h post-exposure. The safety range of the nanoparticles was 50 µl/ml, to determine that PNPs-GA had an optimal safety profile and no cytotoxic effects, as there was no evidence of changes in morphology, internal cellular structures (stress fibers and the cell cortex formed by actin filaments) or viability under the experimental concentrations and conditions employed.

Full Text Available The EURO – The Politics of the New Global Currency, written by David Marsh and published in both English and German, is a very thorough chronicle of the birth of the European common currency, from its early days, almost half a century before, and of its development until nowadays and even beyond, as it includes considerations on short term dynamics. David Marsh describes the story of the euro in a very complex manner, through a detailed, comprehensive and up to date analysis of the gathered data, making a substantial contribution to understanding the linkages between the political, historical, economic, financial, monetary, strategic and personal determinants of the evolution of the single currency.

Determination of the total attenuation coefficient for six contact lens materials using the Beer-Lambert law.

Science.gov (United States)

Hull, C C; Crofts, N C

1996-03-01

The Beer-Lambert law has been used to determine the total attenuation coefficient, mu t, of three hard and three soft contact lens materials. The three hard contact lens materials were PMMA, Polycon II and Boston IV whereas the 3 soft materials were chosen with differing water contents of 38, 55 and 70%, respectively. The total attenuation coefficients of all six materials were obtained from measurements of the axial transmission at 632.8 nm of a series of plano powered lenses varying in axial thickness from 0.5 to 3.5 mm. The value of the total attenuation coefficient depends on both scattering and absorption and hence PMMA and Boston IV, which both incorporated a handling tint, showed significantly higher values (P 0.5) was found between any of the hydrated soft contact lens materials tested.

OBJECTIVE Aortic valve-sparing David procedure has gained broad acceptance. However, few long-term results have been published. We present our results. METHODS More than 450 David procedures have been performed in our institution so far. Of these, 126 patients were operated between July 1993 and December 2000. Median age was 57 (8–83) years and 46 (36.5%) were female. As many as 26 (20.6%) had Marfan syndrome, 21 (16.7%) had acute aortic dissection type A (AADA) and 67 (53.2%) had additional procedures. RESULTS There were six (4.8%) deaths in 30 post-operative period (POD), four of whom had AADA. In the follow-up, there were 32 (25.4%) late deaths, 11 (34.4%) of these were caused by cardiac or underlying disease or op-related. As many as 15 (11.9%) patients were re-operated; six (40%) were Marfan patients and two (13.3%) had early endocarditis. Follow-up echocardiography of 76 (60.3%) event-free patients showed valve insufficiency (AI) ≤ AI I° in 68 (89.5%) and grade II in 7 (9.2%) patients. Leaflet degeneration due to proposed leaflet contact with the straight Dacron graft was not observed. A total of 36 (47.4%) patients were in New York Heart Association (NYHA) class I, 33 (43.4%) in NYHA II, and five (6.6%) were in class III. During the entire follow-up of 790 patient-years, there was no stroke or major bleeding. Survival at 1, 5 and 10 years was 93%, 85% and 70%, respectively. Freedom from valve replacement at 1, 5 and 10 years was 96%, 91% and 87%, respectively. CONCLUSIONS: Regardless of the underlying pathology, valve-sparing David I procedure has acceptable long-term results. Valve-related complications such as stroke or major bleeding is exceedingly low.

Marc-Antoine Laugier’s aesthetic postulates of architectural theory

Directory of Open Access Journals (Sweden)

Kuletin-Ćulafić Irena

2010-01-01

Full Text Available Views on architecture that hold a significant position in architectural theory are the ones by Marc-Antoine Laugier, a French theoretician from the 18th century. The research on his architectural theory that have been carried out so far are quite stereotypical and concern Laugier’s concept of primitive hut as his only significant contribution to architectural theory. It is well-known that the concept of primitive hut plays an important role in Laugier’s theory and it is what actually maintained his reputation up to now. However, by singling out this concept as an independent one, one actually neglects all the other aspects of Laugier’s theory. The aim of this paper is to present multidimensionality of Laugier’s architectural aesthetics by crossing the borders of architecture and viewing Laugier’s ideas in cultural, philosophical, religious and historical context, as well as applying the integrative process and considering the spiritual paths of the enlightenment movement in the mid-18th century. A special attention is paid to considering the aesthetic aspect which represents the gist and an inevitable part of Laugier’s architectural theory. His aesthetic theory is important in forming the classicist style, and despite its radical character, it influenced many architects in France and the rest of Europe. We may see Laugier as one of the first modernists considering his structuralist logic of the constructive circuit of architecture and aesthetic modesty of decoration. Laugier’s functionalist attitude that the constructive circuit should at the same time represent a decorative element of architecture confirms the thesis that modernist approach has its roots in the 18th century.

The extended Beer-Lambert theory for ray tracing modeling of LED chip-scaled packaging application with multiple luminescence materials

Science.gov (United States)

Yuan, Cadmus C. A.

2015-12-01

Optical ray tracing modeling applied Beer-Lambert method in the single luminescence material system to model the white light pattern from blue LED light source. This paper extends such algorithm to a mixed multiple luminescence material system by introducing the equivalent excitation and emission spectrum of individual luminescence materials. The quantum efficiency numbers of individual material and self-absorption of the multiple luminescence material system are considered as well. By this combination, researchers are able to model the luminescence characteristics of LED chip-scaled packaging (CSP), which provides simple process steps and the freedom of the luminescence material geometrical dimension. The method will be first validated by the experimental results. Afterward, a further parametric investigation has been then conducted.

Intercomparison of the terrestrial food chain models FOOD-MARC and ECOSYS

International Nuclear Information System (INIS)

Proehl, G.; Friedland, W.; Paretzke, H.G.

1985-12-01

Time-dependent food chain models, FOOD-MARC and ECOSYS, have been developed independently at the NRPB and at the GSF respectively. Both models are compared with respect to the model assumptions and the parameters used. A further point of this study is the analysis of the influence of actual differences in agricultural conditions in the United Kingdom and the Federal Republic of Germany on the results. A single deposition of 1 Bq/m 2 was assumed of selected radionuclides on an area in agricultural use. The endpoints considered are the resulting activity concentrations in plant and animal foodstuffs as a function of time after deposition. The cumulative concentrations integrated over 50 years are calculated. A deposition in winter (January 1) and another one in summer (July 1) are considered separately to point out the seasonal influence on the contamination of foodstuffs. In this comparison, the products vegetables, grain, roots, milk, meat, and the radionuclides Sr-89/90, Ru-106, Cs-134/137, I-129/131/133, and Pu-239 are taken into account. The activity concentrations in food products are calculated for the times 7 d, 30 d, 100 d, 200 d, 1 a, 2 a, 5 a, 10 a, 20 a, and 50 a after the single deposition on January 1 or July 1. (orig./HP)

Dinner at Orazio's--David Triggle the model of a mentor.

Smith, Susan L

2015-11-15

What does it mean to be a mentor in science? Definitions of mentorship are freely spouted in publications and include concepts such as academic support, professional development, role modeling, interaction, impartment of knowledge, evaluation of work, demonstration of methodology, etc. Perhaps most of us would agree with the duties listed. But just what does it mean, for example, to offer academic support? How might one facilitate professional development for a mentee? While we may agree to the general obligations of a mentor the specifics of what these entail would prove more controversial. This article will illustrate how easy it is to pick out a bad mentor. There are certain elements of conduct that, if practiced, undoubtedly put you in the "bad mentor" category. However, it is very difficult to explain just what it means to be not only an adequate mentor but also a stellar one. It may be easy to list the roles and responsibilities of a mentor but just how should they be performed/carried out? David Triggle is the model of an extraordinary mentor. The conclusion of this paper will focus on some specific mentorship activities David Triggle carried out that illustrate some of the intangible aspects of excellence in mentorship.

An account is given of the life, scientific contributions, and passing of Laurance David Hall (1938-2009), including his early history and education at the University of Bristol, UK, and the synthesis and NMR spectroscopy of carbohydrates and other natural products during ∼20 years of research and teaching at the University of British Columbia in Vancouver, Canada. Lists of graduate students, post-doctoral fellows, and sabbatical visitors are provided for this period. Following a generous endowment by Dr. Herchel Smith, Professor Hall built a new Department of Medicinal Chemistry at Cambridge University, UK, and greatly expanded his researches into the technology and applications of magnetic resonance imaging (MRI) and zero quantum NMR. MRI technology was applied both to medical problems such as the characterization of cartilage degeneration in knee joints, the measurement of ventricular function, lipid localization in animal models of atherosclerosis, paramagnetic metal complexes of polysaccharides as contrast agents, and studies of many other anatomical features, but also to several aspects of materials analysis, including food analyses, process control, and the elucidation of such physical phenomena as the flow of liquids through porous media, defects in concrete, and the visualization of fungal damage to wood. Professor Hall's many publications, patents, lectures, and honors and awards are described, and also his successful effort to keep the Asilomar facility in Pacific Grove, California as the alternating venue for the annual Experimental NMR Conference. Two memorial services for Professor Hall are remembered. Copyright © 2011 Elsevier Inc. All rights reserved.

THE UTILISATION OF GRAPE MARC FOR OBTAINING FEED PROTEIN WITH ETHANOL CONSUMING YEASTS

Full Text Available The research presented in this work has been directed to achieve an optimal and economic medium, for the protein biosynthesis. The carbon source and the mineral elements are provided by the fresh marc diffusion solution and the source of organic nitrogen and growth factors are provided by proteic wine yeast extract. For the alcoholic fermentation it was used a strain of Saccharomyces ellipsoideus and for obtaining the biomass, a strain of Candida robusta. There were performed two series of experiments in which the alcoholic fermentation progress was monitored as follows: by titration of the carbohydrates, at the beginning and respectively at the end of the fermentation; by determining the optical density of the culture medium and by the determination of alcohol in the fermented solution. Protein biosynthesis was monitored by measurement of the alcohol concentration at the beginning and end of the process, by the determination of the optical density of the culture medium, by the determination of residual sugar, and by determining wet and dry biomass. The wet biomass was used for the protein titration. At the termination of the bioprocess was determined the dry matter in the culture medium.

In electron tomography, accurate alignment of tilt series is an essential step in attaining high-resolution 3D reconstructions. Nevertheless, quantitative assessment of alignment quality has remained a challenging issue, even though many alignment methods have been reported. Here, we report a fast and accurate method, tomoAlignEval, based on the Beer-Lambert law, for the evaluation of alignment quality. Our method is able to globally estimate the alignment accuracy by measuring the goodness of log-linear relationship of the beam intensity attenuations at different tilt angles. Extensive tests with experimental data demonstrated its robust performance with stained and cryo samples. Our method is not only significantly faster but also more sensitive than measurements of tomogram resolution using Fourier shell correlation method (FSCe/o). From these tests, we also conclude that while current alignment methods are sufficiently accurate for stained samples, inaccurate alignments remain a major limitation for high resolution cryo-electron tomography.

The aortic valve-sparing David procedure has been applied to the elective treatment of patients with aortic aneurysms with excellent results. The use of this technique in patients with acute aortic dissection type A (AADA) is still a matter of debate. We present our long-term experience with 109 patients with AADA who had the valve-sparing David I procedure. Between July 1993 and October 2015, 109 patients with AADA had the valve-sparing David I procedure at our centre. We conducted a retrospective review with follow-up. The mean age was 54 ± 12 years; 78 (72%) patients were men. Marfan syndrome was present in 6 (5%) patients and bicuspid aortic valve in 3 (3%). Only 4 (4%) patients received the isolated David procedure; 50 (46%) underwent additional proximal, 13 (12%) subtotal and 42 (39%) total aortic arch replacement. The in-hospital mortality rate was 11% ( n  = 12). Intraoperative/discharge echocardiography showed aortic insufficiency ≤ I° in 93 of 97 patients (96%). Mean follow-up time was 8.3 ± 5.7 years. The survival rate after discharge at 1, 5 and 10 years was 94%, 90% and 78%, respectively. Thirteen percent ( n  = 13) of patients underwent valve-related reoperation. Freedom from valve-related reoperation at 1, 5 and 10 years was 96%, 88% and 85%, respectively. Compared to patients who underwent the David I procedure for any reason other than AADA, there were no significant differences in long-term survival rates ( P  = 0.29) and freedom from a valve-related reoperation ( P  = 0.39). The valve-sparing David I procedure has acceptable long-term results even in emergent operations for AADA and is not inferior when performed in elective settings. © The Author 2017.

David Hume filósofo e historiador

Directory of Open Access Journals (Sweden)

Sara Albieri

2004-12-01

Full Text Available Among all the great philosophers, David Hume has the rare merit of joining to a properly philosophical work an equally important output as historian. According to him, the interpretation of history by means of the general principles of political theory must not be guided by ethical or normative considerations, as when judging historic events according to what things ought to be, for instance, in view of the best government, but it should be restricted to explain the exercise of power in the different times, just as it can be established by the testimony of the sources. Only this methodological attitude allows us to avoid the partisan interpretations that try to justify the present by the past, instead of investigating it to corroborate the most appropriate explanation.

Bad-good constraints on a polarity correspondence account for the spatial-numerical association of response codes (SNARC) and markedness association of response codes (MARC) effects.

Science.gov (United States)

Leth-Steensen, Craig; Citta, Richie

2016-01-01

Performance in numerical classification tasks involving either parity or magnitude judgements is quicker when small numbers are mapped onto a left-sided response and large numbers onto a right-sided response than for the opposite mapping (i.e., the spatial-numerical association of response codes or SNARC effect). Recent research by Gevers et al. [Gevers, W., Santens, S., Dhooge, E., Chen, Q., Van den Bossche, L., Fias, W., & Verguts, T. (2010). Verbal-spatial and visuospatial coding of number-space interactions. Journal of Experimental Psychology: General, 139, 180-190] suggests that this effect also arises for vocal "left" and "right" responding, indicating that verbal-spatial coding has a role to play in determining it. Another presumably verbal-based, spatial-numerical mapping phenomenon is the linguistic markedness association of response codes (MARC) effect whereby responding in parity tasks is quicker when odd numbers are mapped onto left-sided responses and even numbers onto right-sided responses. A recent account of both the SNARC and MARC effects is based on the polarity correspondence principle [Proctor, R. W., & Cho, Y. S. (2006). Polarity correspondence: A general principle for performance of speeded binary classification tasks. Psychological Bulletin, 132, 416-442]. This account assumes that stimulus and response alternatives are coded along any number of dimensions in terms of - and + polarities with quicker responding when the polarity codes for the stimulus and the response correspond. In the present study, even-odd parity judgements were made using either "left" and "right" or "bad" and "good" vocal responses. Results indicated that a SNARC effect was indeed present for the former type of vocal responding, providing further evidence for the sufficiency of the verbal-spatial coding account for this effect. However, the decided lack of an analogous SNARC-like effect in the results for the latter type of vocal responding provides an important

Frost, Darrel R.; McDiarmid, Roy W.; Mendelson, Joseph R.

2009-01-01

The Point of View by Gregory Pauly, David Hillis, and David Cannatella misrepresents the motives and activities of the anuran subcommittee of the Scientific and Standard English Names Committee, contains a number of misleading statements, omits evidence and references to critical literature that have already rejected or superseded their positions, and cloaks the limitations of their nomenclatural approach in ambiguous language. Their Point of View is not about promoting transparency in the process of constructing the English Names list, assuring that its taxonomy is adequately reviewed, or promoting nomenclatural stability in any global sense. Rather, their Point of View focuses in large part on a single publication, The Amphibian Tree of Life, which is formally unrelated to the Standard English Names List, and promotes an approach to nomenclature mistakenly asserted by them to be compatible with both the International Code of Zoological Nomenclature and one of its competitors, the PhyloCode.

David Bohm : causality and chance, letters to three women

CERN Document Server

2017-01-01

The letters transcribed in this book were written by physicist David Bohm to three close female acquaintances in the period 1950 to 1956. They provide a background to his causal interpretation of quantum mechanics and the Marxist philosophy that inspired his scientific work in quantum theory, probability and statistical mechanics. In his letters, Bohm reveals the ideas that led to his ground breaking book Causality and Chance in Modern Physics. The political arguments as well as the acute personal problems contained in these letters help to give a rounded, human picture of this leading scientist and twentieth century thinker.

An important area of applied mathematics is the Chemical reaction network theory. The behavior of real world problems can be modeled by using this theory. Due to applications in theoretical chemistry and biochemistry, it has attracted researchers since its foundation. It also attracts pure mathematicians because it involves interesting mathematical structures. In this report, we compute newly defined topological indices, namely, Arithmetic-Geometric index (AG1 index), SK index, SK1 index, and SK2 index of the dominating David derived networks [1, 2, 3, 4, 5].

Green Extraction from Pomegranate Marcs for the Production of Functional Foods and Cosmetics

Directory of Open Access Journals (Sweden)

Raffaella Boggia

2016-10-01

Full Text Available The aim of this study was to investigate the potential of retrieving polyphenolic antioxidants directly from wet pomegranate marcs: the fresh by-products obtained after pomegranate juice processing. These by-products mainly consist of internal membranes (endocarp and aril residues. Even if they are still edible, they are usually discharged during juice production and, thus, they represent a great challenge in an eco-sustainable industrial context. Green technologies, such as ultrasound assisted extraction (UAE and microwave assisted extraction (MAE, have been employed to convert these organic residues into recycled products with high added value. UAE and MAE were used both in parallel and in series in order to make a comparison and to ensure exhaustive extractions, respectively. Water, as an environmentally friendly extraction solvent, has been employed. The results were compared with those ones coming from a conventional extraction. The most promising extract, in terms of total polyphenol yield and radical scavenging activity, has been tested both as a potential natural additive and as a functional ingredient after its incorporation in a real food model and in a real cosmetic matrix, respectively. This study represents a proposal to the agro-alimentary sector given the general need of environmental “responsible care”.

Corpses of Metaphor. Images of Death in David Leavitt and Jamaica Kincaid

Directory of Open Access Journals (Sweden)

Fiorenzo Iuliano

2010-10-01

Full Text Available This essay analyzes two works, My Brother by Jamaica Kincaid, and "Saturn Street" by David Leavitt, investigating the construction of homosexuality as a process accomplished by resorting to illness (AIDS and death. In both works, indeed, the slow and dramatic course of AIDS amounts to the progressive unveiling of homosexuality as a social threat or a cause of anxiety and repulsion. The two works are set in different contexts: whereas Jamaica Kincaid refers to the problematic situation of homosexuality in the Caribbean, David Leavitt explores the social and cultural scenario of the 1990s Los Angeles, in the wake of a by now ended utopian confidence in science and technology.  This comparative approach helps us understand the political dynamics through which, in different and, to some extents, opposite realities, the social stigma of AIDS worked as a means to construct homosexual identity and set it apart from the sanitized spectrum of normal and sanctioned sexual behaviors. The point I want to make in this essay is that the corpse is used as an effective metaphor for a dehumanized depiction of male homosexual and ill subjects.

Decay of postexercise augmentation in the Lambert-Eaton myasthenic syndrome: effect of cooling.

Science.gov (United States)

Maddison, P; Newsom-Davis, J; Mills, K R

1998-04-01

The effect of local cooling on surface recorded compound muscle action potential (CMAP) amplitude was studied in five patients with the Lambert-Eaton myasthenic syndrome (LEMS). The time course of decay of postexercise augmentation of CMAP amplitude characteristically seen in patients with LEMS was determined. We recorded the CMAP from abductor digiti minimi (ADM) in response to supramaximal stimulation of the ulnar nerve. Thirty consecutive stimuli were delivered at 1 Hz immediately after a 10-second period of maximal voluntary contraction. Skin surface temperature was recorded throughout. Initial testing at approximately 30 degrees C was repeated after cooling the hand and forearm by 6 to 12 degrees C. The effects of blood flow on temperature were counteracted by the application of a sphygmomanometer cuff, inflated above systolic blood pressure. The CMAP amplitude following contraction decayed in an exponential manner both during warm and cold conditions. The mean time constant for decay (1/b) in all patients was increased by approximately 25% after cooling. This prolongation of the period of postexercise augmentation of CMAP amplitude in LEMS after cooling concurs with patient reports of symptomatic improvement in cold weather. The mechanism for this benefit is thought to be due to reduction in the rate of removal of calcium ions from the nerve terminal following stimulation, similar to that seen in animal models of short-term synaptic enhancement.

Cross talk in the Lambert-Beer calculation for near-infrared wavelengths estimated by Monte Carlo simulations.

Science.gov (United States)

Uludag, K; Kohl, M; Steinbrink, J; Obrig, H; Villringer, A

2002-01-01

Using the modified Lambert-Beer law to analyze attenuation changes measured noninvasively during functional activation of the brain might result in an insufficient separation of chromophore changes ("cross talk") due to the wavelength dependence of the partial path length of photons in the activated volume of the head. The partial path length was estimated by performing Monte Carlo simulations on layered head models. When assuming cortical activation (e.g., in the depth of 8-12 mm), we determine negligible cross talk when considering changes in oxygenated and deoxygenated hemoglobin. But additionally taking changes in the redox state of cytochrome-c-oxidase into account, this analysis results in significant artifacts. An analysis developed for changes in mean time of flight--instead of changes in attenuation--reduces the cross talk for the layers of cortical activation. These results were validated for different oxygen saturations, wavelength combinations and scattering coefficients. For the analysis of changes in oxygenated and deoxygenated hemoglobin only, low cross talk was also found when the activated volume was assumed to be a 4-mm-diam sphere.

The application of extended modified Lambert Beer model for measurement of blood carboxyhemoglobin and oxyhemoglobin saturation

2014-05-01

Full Text Available This work presents the use of extended Modified Lambert Beer (MLB model for accurate and continuous monitoring of percent blood carboxyhemoglobin (COHb (SCO and oxyhemoglobin (OxyHb saturation (SO2 via a fitting procedure. This quantification technique is based on the absorption characteristics of hemoglobin derivatives in the wavelength range of 520–600 nm to give the best estimates of the required parameters. A comparison of the performance of the developed model and MLB law is made using attenuation data from Monte Carlo simulations for a two-layered skin model. The results revealed a lower mean absolute error of 0.4% in the values estimated by the developed model as compared to 10% that is given by the MLB law. This study showed that the discussed approach is able to provide consistent and accurate measurement of blood SO2 and SCO across different skin pigmentations suggesting that it may potentially be used as an alternative means for clinical diagnosis of carbon monoxide (CO poisoning.

The influence of temperature and time on the stability of the antioxidant activity and colour parameters of grape marc ethanolic extract

Directory of Open Access Journals (Sweden)

Elena CRISTEA

2015-12-01

Full Text Available The interest to replace synthetic food colorants, preservatives and antioxidants in beverages with natural ones is leading researchers to explore the polyphenols of winery wastes. It is of great interest to see if these compounds could replace synthetic dyes in drinks. However, it is still necessary to study the stability of extracts containing grape phenolics during various technological treatments. This paper presents the study of the stability of the 50% ethanolic extract of marc resulting from the winemaking process. The extract was subjected to the following temperatures: -2oC for 12 hours; 4oC for 12 hours; 40oC for 15 minutes, 60oC for 15 minutes, 80oC for 15 minutes and 100oC for 2 minutes; after that the antioxidant activity and the colour parameters (CIELab were measured. Three sets of extracts were kept for 2 weeks at -2oC, 4oC, and 25-30oC and afterwards the parameters mentioned above were measured once again. Furthermore, the total content of polyphenols and the content of tannins were determined using the Folin-Ciocalteu method. The results were expressed in mg gallic acid equivalents per litre and mg tannic acid equivalents per litre, respectively. The antioxidant activity was determined using the method based on the interaction with the ABTS radical, the results being expressed in % inhibition. The results have shown that the colour (CIELab parameters and the antioxidant activity of the ethanolic extract of marc are relatively stable during thermal processes. High temperatures as well as prolonged storage at room temperature increased the values of antioxidant activity, chroma, and redness. However, they also produced the most significant effect of the overall colour of the extract, leading to the degradation of blue pigments and a shift towards orange hues.

New software for computer-assisted dental-data matching in Disaster Victim Identification and long-term missing persons investigations: "DAVID Web".

Clement, J G; Winship, V; Ceddia, J; Al-Amad, S; Morales, A; Hill, A J

2006-05-15

In 1997 an internally supported but unfunded pilot project at the Victorian Institute of Forensic Medicine (VIFM) Australia led to the development of a computer system which closely mimicked Interpol paperwork for the storage, later retrieval and tentative matching of the many AM and PM dental records that are often needed for rapid Disaster Victim Identification. The program was called "DAVID" (Disaster And Victim IDentification). It combined the skills of the VIFM Information Technology systems manager (VW), an experienced odontologist (JGC) and an expert database designer (JC); all current authors on this paper. Students did much of the writing of software to prescription from Monash University. The student group involved won an Australian Information Industry Award in recognition of the contribution the new software could have made to the DVI process. Unfortunately, the potential of the software was never realized because paradoxically the federal nature of Australia frequently thwarts uniformity of systems across the entire country. As a consequence, the final development of DAVID never took place. Given the recent problems encountered post-tsunami by the odontologists who were obliged to use the Plass Data system (Plass Data Software, Holbaek, Denmark) and with the impending risks imposed upon Victoria by the decision to host the Commonwealth Games in Melbourne during March 2006, funding was sought and obtained from the state government to update counter disaster preparedness at the VIFM. Some of these funds have been made available to upgrade and complete the DAVID project. In the wake of discussions between leading expert odontologists from around the world held in Geneva during July 2003 at the invitation of the International Committee of the Red Cross significant alterations to the initial design parameters of DAVID were proposed. This was part of broader discussions directed towards developing instruments which could be used by the ICRC's "The Missing

Subject in Tractatus according to David Pears

Directory of Open Access Journals (Sweden)

M Hoseinzadeh Yazdi

2013-02-01

Full Text Available Subjectivism is viewed as one of the most fundamental underpinnings of modern philosophy. In modern philosophy, subject takes up a new position in human knowledge. The formation of the concept of subject is a decisive turn with which the modern philosophy starts. Considering the centrality of subjectivism in modern philosophy, this article attempts to explain subject in Tractatus according to David Pears. A review of Wittgenstein’s earlier teachings reveals that he considers a fundamental limitation for language. The subject serves as a point of view from which the language can be understood. The subject is the presupposition of understanding. Another way of putting this would be to say that any experience is understood from a point of view which is not represented in that experience. Regarding this, it seems that earlier Wittgenstein is somehow subjectivist. This specific form of subjectivism is different from Kantian subjectivism.

2017-10-01

Samples of Satsuma mandarin (Citrus unshiu Marc.) nectar, honey sac content and honey were analyzed by FTIR-ATR spectroscopy and reference methods. The spectral analysis allowed detection of the major chemical constituents in C. unshiu nectar-to-honey transformation pathway thus providing information on the intensity and location of the compositional changes occurring during this process. The preliminary results showed that in average more than one-third of sugar-related nectar-to-honey conversion takes place directly in the honey sac; the average sugar content (w/w) was 17.93% (nectar), 47.03% (honey sac) and 79.63% (honey). FTIR-ATR results showed great spectral similarity of analyzed honey samples and small degree variations in both sugar and water content in nectar samples. The spectral data revealed distinctive differences in the chemical composition of individual honey sac contents with the most intensive and complex absorption envelope in the spectral region between 1175 and 950cm -1 (glucose, fructose and sucrose absorption bands).

Photon path distribution and optical responses of turbid media: theoretical analysis based on the microscopic Beer-Lambert law.

Science.gov (United States)

Tsuchiya, Y

2001-08-01

A concise theoretical treatment has been developed to describe the optical responses of a highly scattering inhomogeneous medium using functions of the photon path distribution (PPD). The treatment is based on the microscopic Beer-Lambert law and has been found to yield a complete set of optical responses by time- and frequency-domain measurements. The PPD is defined for possible photons having a total zigzag pathlength of l between the points of light input and detection. Such a distribution is independent of the absorption properties of the medium and can be uniquely determined for the medium under quantification. Therefore, the PPD can be calculated with an imaginary reference medium having the same optical properties as the medium under quantification except for the absence of absorption. One of the advantages of this method is that the optical responses, the total attenuation, the mean pathlength, etc are expressed by functions of the PPD and the absorption distribution.

Also, the log of the ratio of PMFs from the peel (ExExEm was significantly correlated with the SS:acid ratio (R2 = 0.8207. While the latter correlation was not as strong as the former, it does demonstrate the opportunity to develop a non-destructive field measurement of fluorescent peel compounds as an indirect index of fruit maturity.

Discrimination and risk assessment due to the volatile compounds and the inorganic elements present in the Greek marc distillates Tsipouro and Tsikoudia

Full Text Available Tsipouro and Tsikoudia are two denominations with geographic indications of the traditional Greek marc distillate, which is produced in continental Greece and in the island of Crete respectively. It is produced by the Greek winegrowers as well as by the professional distillers. To provide data on the safety of domestic Tsipouro and Tsikoudia distillates for human consumption and to draw conclusions from any essential results, which might have an impact on the quality of this product, 23 samples were analysed for: (a Volatile compounds by the use of gas chromatography, (b Inorganic elements, using atomic absorption spectrometry and (c the pH values through-out using standard methods. Data revealed differences between these two denominations, which have been confirmed by the application of a statistic analysis and a PCA. Thus, Tsikoudia was found to contain statistically higher amounts of acetalde-hyde. However, the levels that have been observed did not exceed the official limits. Most of the Tsipouro and Tsikoudia samples also contained low concentrations of estragol, an anise compound, lead and copper, which do not represent a risk to consumer health due to their toxicity. On the other hand, the total concentration of higher alcohols was higher than the official minimum limit (140 g.hl-1 Absolute Alcohol-AA, while the amylic alcohols rarely exceeded 300 g.hl-1 AA. The high concentrations of ethyl acetate (>300 g.hl-1 AA and ethyl lactate in a few samples showed the necessity of limiting unwanted fermentations in the grape pomace. The analytical study showed that the quality of the marc distillate is, generally, satisfactory. However, it revealed great differences between Tsipouro and Tsikoudia even among the samples of each denomination and, con-sequently, these domestic distillates need standardization and a more systematic production.

I claimed that if the nature of the world is such that every event and phenomenon which occurs has a cause of some sort, then probability must be defined subjectively; that is, “as a measure of our uncertainty about the likelihood of occurrence of some event or phenomenon, based upon evidence that need not derive solely from past frequencies of ‘collectives’ or ‘classes.’” I further claimed that the nature of the world is indeed such that all events and phenomena have prior causes, and that this fact compels us to adopt a subjective definition of probability.David Howden has recently published what he claims is a refutation of my argument in his article “Single Trial Probability Applications: Can Subjectivity Evade Frequency Limitations” (Howden 2009. Unfortunately, Mr. Howden appears to not have understood my argument, and his purported refutation of my subjective definition consequently amounts to nothing more than a concatenation of confused and fallacious ideas that are completely irrelevant to my argument. David Howden has thus failed in his attempt to vindicate Richard von Mises’s definition of probability.

Robust yeasts with high inhibitor, temperature, and osmotic tolerance remain a crucial requirement for the sustainable production of lignocellulosic bioethanol. These stress factors are known to severely hinder culture growth and fermentation performance. Grape marc was selected as an extreme environment to search for innately robust yeasts because of its limited nutrients, exposure to solar radiation, temperature fluctuations, weak acid and ethanol content. Forty newly isolated Saccharomyces cerevisiae strains gave high ethanol yields at 40°C when inoculated in minimal media at high sugar concentrations of up to 200 g/l glucose. In addition, the isolates displayed distinct inhibitor tolerance in defined broth supplemented with increasing levels of single inhibitors or with a cocktail containing several inhibitory compounds. Both the fermentation ability and inhibitor resistance of these strains were greater than those of established industrial and commercial S. cerevisiae yeasts used as control strains in this study. Liquor from steam-pretreated sugarcane bagasse was used as a key selective condition during the isolation of robust yeasts for industrial ethanol production, thus simulating the industrial environment. The isolate Fm17 produced the highest ethanol concentration (43.4 g/l) from the hydrolysate, despite relatively high concentrations of weak acids, furans, and phenolics. This strain also exhibited a significantly greater conversion rate of inhibitory furaldehydes compared with the reference strain S. cerevisiae 27P. To our knowledge, this is the first report describing a strain of S. cerevisiae able to produce an ethanol yield equal to 89% of theoretical maximum yield in the presence of high concentrations of inhibitors from sugarcane bagasse. This study showed that yeasts with high tolerance to multiple stress factors can be obtained from unconventional ecological niches. Grape marc appeared to be an unexplored and promising substrate for the

Sequential fluctuating paraneoplastic ocular flutter-opsoclonus-myoclonus syndrome and Lambert-Eaton myasthenic syndrome in small-cell lung cancer.

LENUS (Irish Health Repository)

Simister, Robert J

2011-03-01

Paraneoplastic cerebellar degeneration may occur in association with Lambert-Eaton myasthenic syndrome (LEMS), but to our knowledge, the co-occurrence of paraneoplastic opsoclonus-myoclonus syndrome and LEMS has not been previously reported. A 67-year-old woman presented with a complex partial seizure and evolving ocular flutter, opsoclonus, myoclonus and \\'cerebellar\\' signs, all of which improved spontaneously within 6 weeks. Approximately 8 weeks after symptom onset, the patient became encephalopathic, she had a further complex partial seizure, and she became areflexic with potentiation of deep tendon reflexes. Radiological, bronchoscopic and histological investigations revealed small-cell lung cancer, and neurophysiological investigations confirmed a diagnosis of LEMS. High-titre anti-P\\/Q-type voltage-gated calcium-channel antibodies were identified in the serum, which increased as the signs of opsoclonus and myoclonus resolved. The encephalopathy and clinical features of LEMS responded dramatically to chemotherapy and radiotherapy. Spontaneous improvement of paraneoplastic opsoclonus-myoclonus syndrome may occur, and this syndrome may occur in association with LEMS. Antivoltage-gated calcium-channel antibodies are not implicated in the pathogenesis of paraneoplastic opsoclonus-myoclonus syndrome.

LeBlanc, Serge Emile; Atanya, Monica; Burns, Kevin; Munger, Rejean

It is well known that red blood cell scattering has an impact on whole blood oximetry as well as in vivo retinal oxygen saturation measurements. The goal of this study was to quantify the impact of small angle forward scatter on whole blood oximetry for scattering angles found in retinal oximetry light paths. Transmittance spectra of whole blood were measured in two different experimental setups: one that included small angle scatter in the transmitted signal and one that measured the transmitted signal only, at absorbance path lengths of 25, 50, 100, 250 and 500 µm. Oxygen saturation was determined by multiple linear regression in the 520-600 nm wavelength range and compared between path lengths and experimental setups. Mean calculated oxygen saturation differences between setups were greater than 10% at every absorbance path length. The deviations to the Beer-Lambert absorbance model had different spectral dependences between experimental setups, with the highest deviations found in the 520-540 nm range when scatter was added to the transmitted signal. These results are consistent with other models of forward scatter that predict different spectral dependences of the red blood cell scattering cross-section and haemoglobin extinction coefficients in this wavelength range.

A closed-form solution for steady-state coupled phloem/xylem flow using the Lambert-W function.

Science.gov (United States)

Hall, A J; Minchin, P E H

2013-12-01

A closed-form solution for steady-state coupled phloem/xylem flow is presented. This incorporates the basic Münch flow model of phloem transport, the cohesion model of xylem flow, and local variation in the xylem water potential and lateral water flow along the transport pathway. Use of the Lambert-W function allows this solution to be obtained under much more general and realistic conditions than has previously been possible. Variation in phloem resistance (i.e. viscosity) with solute concentration, and deviations from the Van't Hoff expression for osmotic potential are included. It is shown that the model predictions match those of the equilibrium solution of a numerical time-dependent model based upon the same mechanistic assumptions. The effect of xylem flow upon phloem flow can readily be calculated, which has not been possible in any previous analytical model. It is also shown how this new analytical solution can handle multiple sources and sinks within a complex architecture, and can describe competition between sinks. The model provides new insights into Münch flow by explicitly including interactions with xylem flow and water potential in the closed-form solution, and is expected to be useful as a component part of larger numerical models of entire plants. © 2013 John Wiley & Sons Ltd.

Masculinity and violence in David Fincher’s "Fight Club"

Directory of Open Access Journals (Sweden)

Leire Ituarte Pérez

2017-12-01

Full Text Available In this article we address a hermeneutic approach to David Fincher’s Fight Club. Inspired by some of the methodological principles of Psychoanalysis and Queer Theory the study tries to thresh the details of the representation of Masculinity in the film. Departing from the hypothesis that such representation in the film is closely linked to the masculine castration anxiety, the essay traces the recurrent and more or less parodic, more or less subliminal allusions to emasculation as well as the fetishistic compensatory strategies displayed. The analysis concludes that the overwhelming mise en scène of the masculine Oedipal scenario in the film pursues to underpin an hegemonic discourse of Masculinity threatened by the taboo of Homosexuality. Hence, the prominent erotisization of masculine masochism reveals itself, in all its ambivalence, as a performative strategy to institutionalise a heteronormative sexual regime.

Effect of the concentration of magnetic grains on the linear-optical-absorption coefficient of ferrofluid-doped lyotropic mesophases: deviation from the Beer-Lambert law.

Science.gov (United States)

Cuppo, F L S; Gómez, S L; Figueiredo Neto, A M

2004-04-01

In this paper is reported a systematic experimental study of the linear-optical-absorption coefficient of ferrofluid-doped isotropic lyotropic mixtures as a function of the magnetic-grains concentration. The linear optical absorption of ferrolyomesophases increases in a nonlinear manner with the concentration of magnetic grains, deviating from the usual Beer-Lambert law. This behavior is associated to the presence of correlated micelles in the mixture which favors the formation of small-scale aggregates of magnetic grains (dimers), which have a higher absorption coefficient with respect to that of isolated grains. We propose that the indirect heating of the micelles via the ferrofluid grains (hyperthermia) could account for this nonlinear increase of the linear-optical-absorption coefficient as a function of the grains concentration.

The continent of Antarctica has approximately the same surface area as the continental United States, though we know significantly less about its underlying geology and seismic activity. In recent years, improvements in seismic instrumentation, battery technology, and field deployment practices have allowed for continuous broadband stations throughout the dark Antarctic winter. We utilize broadband seismic data from a recent experiment (TAMNNET), which was originally proposed as a structural seismology experiment, for seismic event detection. Our target is to address fundamental questions about regional-scale crustal and environmental seismicity in the study region that comprises the Transantarctic Mountain area of Victoria and Oates Land. We identify most seismicity emanating from David Glacier, upstream of the Drygalski Ice Tongue, which has been documented by several other studies. In order to improve the catalog completeness for the David Glacier area, we utilize a matched-filter technique to identify potential missing earthquakes that may not have been originally detected. This technique utilizes existing cataloged waveforms as templates to scan through continuous data and to identify repeating or nearby earthquakes. With a more robust catalog, we evaluate relative changes in icequake positions, recurrence intervals, and other first-order information. In addition, we attempt to further refine locations of other regional seismicity using a variety of methods including body and surface wave polarization, beamforming, surface wave dispersion, and other seismological methods. This project highlights the usefulness of archiving raw datasets (i.e., passive seismic continuous data), so that researchers may apply new algorithms or techniques to test hypotheses not originally or specifically targeted by the original experimental design.

Full Text Available There is a strong relationship between the chemical characteristics of chemical compounds and their molecular structures. Topological indices are numerical values associated with the chemical molecular graphs that help to understand the physical features, chemical reactivity, and biological activity of chemical compound. Thus, the study of the topological indices is important. M-polynomial helps to recover many degree-based topological indices for example Zagreb indices, Randic index, symmetric division idex, inverse sum index etc. In this article we compute M-polynomials of dominating David derived networks of the first type, second type and third type of dimension n and find some topological properties by using these M-polynomials. The results are plotted using Maple to see the dependence of topological indices on the involved parameters.

Explicit Expressions for Solar Panel Equivalent Circuit Parameters Based on Analytical Formulation and the Lambert W-Function

Directory of Open Access Journals (Sweden)

Javier Cubas

2014-06-01

Full Text Available Due to the high dependence of photovoltaic energy efficiency on environmental conditions (temperature, irradiation..., it is quite important to perform some analysis focusing on the characteristics of photovoltaic devices in order to optimize energy production, even for small-scale users. The use of equivalent circuits is the preferred option to analyze solar cells/panels performance. However, the aforementioned small-scale users rarely have the equipment or expertise to perform large testing/calculation campaigns, the only information available for them being the manufacturer datasheet. The solution to this problem is the development of new and simple methods to define equivalent circuits able to reproduce the behavior of the panel for any working condition, from a very small amount of information. In the present work a direct and completely explicit method to extract solar cell parameters from the manufacturer datasheet is presented and tested. This method is based on analytical formulation which includes the use of the Lambert W-function to turn the series resistor equation explicit. The presented method is used to analyze commercial solar panel performance (i.e., the current-voltage–I-V–curve at different levels of irradiation and temperature. The analysis performed is based only on the information included in the manufacturer’s datasheet.

Basis material decomposition in spectral CT using a semi-empirical, polychromatic adaption of the Beer-Lambert model

Following the development of energy-sensitive photon-counting detectors using high-Z sensor materials, application of spectral x-ray imaging methods to clinical practice comes into reach. However, these detectors require extensive calibration efforts in order to perform spectral imaging tasks like basis material decomposition. In this paper, we report a novel approach to basis material decomposition that utilizes a semi-empirical estimator for the number of photons registered in distinct energy bins in the presence of beam-hardening effects which can be termed as a polychromatic Beer-Lambert model. A maximum-likelihood estimator is applied to the model in order to obtain estimates of the underlying sample composition. Using a Monte-Carlo simulation of a typical clinical CT acquisition, the performance of the proposed estimator was evaluated. The estimator is shown to be unbiased and efficient according to the Cramér-Rao lower bound. In particular, the estimator is capable of operating with a minimum number of calibration measurements. Good results were obtained after calibration using less than 10 samples of known composition in a two-material attenuation basis. This opens up the possibility for fast re-calibration in the clinical routine which is considered an advantage of the proposed method over other implementations reported in the literature.

In valve-sparing aortic root replacement (VSARR), how to reproduce Valsalva sinus has been an issue. In the original David V procedure, they put plication stitches at sinotubular junction level, although the reefing effect is limited and distal graft remains larger than native. Other modified techniques are two-grafts technique and ready-made Valsalva graft. However, the former needs graft-graft anastomosis and may not be cost-effective, while in the latter, the shape of sinus is fixed and minor adjustment is difficult. David V University of Tokyo modification (David V-UT) is our original solution to that, creating pseudosinus with one straight graft by longitudinal size-reduction running sutures above each pseudosinus. The purpose of the present study is to investigate long-term outcome of David V-UT. We analyzed 59 David V-UT patients from February 2004 to February 2013 and long-term outcomes were investigated by Kaplan-Meier methods. Risk factors for adverse events "death or recurrent aortic insufficiency (AI) with or without aortic valve reoperation" were analyzed by using Cox proportional hazard models. Mean age was 33.1±14.5 years, and 38 patients (64%) were male. Marfan syndrome (MFS) accounts for 47 patients (80%). Only one patient was with bicuspid aortic valve. No in-hospital mortality was observed. Mean follow-up was 4.9±2.4 years. Estimated survival was 94.0±3.4% at 5 years. Freedoms from aortic valve reoperation and recurrent AI greater than mild were 95.7±3.0% and 88.9±4.7% at 5 years, respectively. In Cox proportional hazard analysis, preoperative AI greater than mild and Z score of annular diameter were significant risks for adverse events (p=0.027 and 0.045, hazard ratio 6.084 and 1.432, 95% C.I. 1.225-30.21 and 1.008-2.035, respectively). Even in Marfan-characterized population, David V-UT provided satisfactory long-term outcome, comparable to other VSARR modifications.

Infinite potential the life and times of David Bohm

CERN Document Server

Peat, David

1997-01-01

Throughout his life, David Bohm felt himself to be different, and this was reflected in his lifestyle and in his physics. His life was one of unfulfilled searching. If one compares mainstream physics to the church, with a solid hierarchy of cardinals, archbishops and bishops, Bohm was an ascetic hermit who would occasionally come in from the wilderness with a compelling message, only to disappear again. Bohmian quantum mechanics is not part of mainstream physics, but for those who do cross over, like John Bell, the commitment can be rewarding. In the post-war 'Un-American Activities' purge, Bohm lost a prestigious job at Princeton and t emporarily his US citizenship, and his nomadic career took him to Brazil, Israel and Bristol before he finally settled in London's Birkbeck College. A sensitive-written book about a gifted, unusual and sometimes provocative figure. The interaction between Bohm and Oppenheimer is especially interesting, while Bohm's later life was bizarre.

EN LA TEORÍA ECONÓMICA DE DAVID RICARDO

Full Text Available Este artículo tiene como objetivo central analizar el papel del recurso tierra en la teoría económica de David Ricardo como primer acercamiento al análisis económico de los recursos naturales. Esto se realiza mediante una revisión bibliográfica analítica de la obra de Ricardo y de otros autores en torno a la misma. En este sentido, se examina el concepto de renta de la tierra, así como los planteamientos en torno a la llamada ley de los rendimientos decrecientes. Asimismo, se establecen algunas reflexiones críticas con relación al enfoque de la renta de la tierra. Un resultado importante del trabajo es que en el análisis de la renta de Ricardo está ausente el concepto de costo de oportunidad, lo cual implica una reconsideración del concepto de renta para abordar el análisis económico de recursos naturales.

A Staged Reading of the Play: TRANSCENDENCE: Relativity and Its Discontents by Robert Marc Friedman

Science.gov (United States)

Friedman, Robert Marc

2015-04-01

TRANSCENDENCE explores aspects of Einstein's life and his general theory of relativity at the time of the theory's creation and initial reception. While being faithful to historical scholarship, the play creates its own theatrical reality aiming to engage emotions and intellect. Those who strive for transcendence must nevertheless also confront the harsh realities of living in specific time-bound social contexts. Universal constants that anchor physical theory in an objective reality, as Einstein believed, do not readily have equivalents in notions of identity, duty, loyalty, and excellence. In November 1915 after toiling for years in Zurich, Prague, and now Berlin, Einstein achieved his general theory of relativity. When in 1919 British astronomers announced evidence for the bending of starlight by the sun as Einstein had predicted, he soon surprisingly found himself an international celebrity. Expectations arose that he would be called to Stockholm. But the Nobel Committee for Physics refused to acknowledge ``speculations'' such Einstein's. The dismissal of relativity entailed principled and biased opposition, and not simply mistakes in evaluation. Several committee members agreed that Einstein must not receive a Prize. Join us for a dramatic staged reading of TRANSCENDENCE, a play by the science historian Robert Marc Friedman (http://www.hf.uio.no/iakh/english/people/aca/robertfr/index.html) and directed by James Glossman, Lecturer in Directing and Shakespeare, Johns Hopkins University. After the performance, the playwright, director and actors will be available for a talk-back audience discussion.

2015-12-01

Full Text Available David Roberts' views of Córdoba were carried out in 1833 and later redrafted as lithographs, engravings, and oils. These artworks enjoyed great commercial success and international diffusion due to their thematic and undoubted artistic value. The authors analyze their documentary value as a graphic record -prior to the advent of photography- of the urban landscape and architecture of Cordoba, a city now denominated a World Heritage Site. These images are studied here for the first time as a group, since they are either virtually untraceable or dispersed in museums throughout the world. In addition, these views have been contextualized with information concerning the artist and his Spanish journey, including a letter that he wrote from Córdoba. The documentary reliability of every image is also assessed, while the significant transformations of the places represented are indicated.Las vistas realizadas en Córdoba por David Roberts en 1833, reelaboradas como litografías, grabados y óleos, han gozado de gran éxito comercial y difusión internacional por su temática e indudable interés artístico. Esta investigación profundiza en su valor documental como registros gráficos previos a la aparición de la fotografía, del paisaje y la arquitectura de una ciudad hoy considerada Patrimonio de la Humanidad. Las imágenes presentadas se analizan por primera vez como conjunto, pues algunas son de difícil localización o están dispersas en museos de todo el mundo, y se contextualizan con datos sobre el pintor y su viaje por España, considerando una carta que éste escribió desde Córdoba. También se valora la fiabilidad documental de cada vista, a la vez que se detectan significativas transformaciones de los lugares representados.

Optical quantitation of absorbers in variously shaped turbid media based on the microscopic Beer-Lambert law. A new approach to optical computerized tomography.

Science.gov (United States)

Tsuchiya, Y; Urakami, T

1998-02-09

To determine the concentrations of an absorber in variously shaped turbid media such as human tissue, we propose analytical expressions for diffuse re-emission in time and frequency domains, based on the microscopic Beer-Lambert law that holds true when we trace a zigzag photon path in the medium. Our expressions are implicit for the scattering properties, the volume shape, and the source-detector separation. We show that three observables are sufficient to determine the changes in the concentration and the absolute concentrations of an absorber in scattering media as long as the scattering property remains constant. The three observables are: the re-emission, the mean pathlength or group delay, and the extinction coefficient of the absorber. We also show that our equations can be extended to describe photon migration in nonuniform media. The validity of the predictions is confirmed by measuring a tissue-like phantom.

Thinking outside the Chinese Box: David Mitchell and Murakami Haruki’s subversion of stereotypes about Japan

Directory of Open Access Journals (Sweden)

Chikako Nihei

2009-12-01

Full Text Available Japan has often been portrayed by orientalist stereotypes, as famously framed by Edward Said, that were mainly constituted within Europe and North America. There are two distinct streams of orientalist discourse around Japan: traditional Orientalism and techno-Orientalism. Here the West speaks of the Other/the non-West rather than allowing it to speak for itself. In regards to the discourse of ‘Otherness’, another interesting phenomenon is Japan’s self-Orientalising: through the internalisation of the Western Orientalist discourse, Japan identifies itself and constructs its own subjectivity. In his literary works, the author David Mitchell attempts to subvert the conventional orientalist approach to describe Japan while concurrently maintaining his position as a British observer. He makes use of Western perspectives to cater to his Western readers’ preference for Japan’s traditional and cultural elements, and yet at the same time attempts to subvert stereotypes. Mitchell’s approach is reminiscent of Japanese author Murakami Haruki’s use of both ‘Japaneseness’ and ‘un-Japaneseness’ in his works. Mitchell also learnt the importance of the use of the subjective narrative voice from Murakami. In this article, I examine how David Mitchell, as a western author, attempts to go beyond orientalist stereotypes, and how his writing is influenced by Murakami Haruki.

Automated georeference of the 1: 20,000 Romanian maps under Lambert-Cholesky (1916-1959) projection system

Before the 1918 Union, the Romanian territories were subject of several dominations, for which reason the cartographic data base for each Romanian province was different from an area to another. Starting from the second half of the 19th century, Valachia, Moldavia and Dobrogea (Dacia Pontica or Scitia Minor) field mapping was made, implicitly cartographic representations, different as structure. The projection systems used, the chosen geoid, the nomenclature and the distribution of the map pages were not uniform. For an example, the Bessel ellipsoid and the Cassini cross cylindrical projection were used especially to the eastern side of the Zimnicea central meridian (23 degree east from Paris), while to its western side the Bonne conic equivalent projection was used, as defined on the Clarke ellipsoid (Năstase, 1975, pages 86-87). In the other Romanian provinces, such as Transylvania, Romanian Banat, Bessarabia (Moldavia Republic) and Southern Bucovina, the major part of the cartographic products (surface contour maps) were made as polyhedral projections. During the World War I, when artillery was a redoubtable weapon a necessary idea was born to articulate an unitary cartographic projection concerning the entire Romanian territory, which should respond to the principle of conformity. Between 1916-1917, pursuant to the above argumented measure, a new datum/location surface, a new projection system and a new nomenclature were introduced. The Lambert projection system was used as modified by the French land surveyor, the mathematician and officer Andre Louis Cholensky. He was born in 1875 in Mont Guyon and passed away on the battle field in Northern France in the month of August 1918. During September 1916 up to February 1918, following the Franco-Romanian military convention, he was a Commander of the Geographic Department of the Romanian Army (Brezinsky-Gross-Cholensky, 1996). The calculations for passing from the various projections (as previously mentioned

In early 1970s first personal desk-top computers started to be available in hospitals. Mr Price was one of the pioneers introducing his own software to identify Marmarou's model of CSF space during infusion studies to diagnose patients suffering from hydrocephalus. His closed-loop control system for infusion of mannitol to manage patients at risk of intracranial hypertension was designed in 1977. The system worked successfully for 10 years in Pinderfields Hospital in Wakefield, UK. In the middle 1980's he initiated international cooperation with Children's Health Centre in Poland in long-term computer-assisted monitoring and analysis of ICP. Software designed in a course of this cooperation paved the way for contemporary package of ICM+ (Intensive Care Monitor, University of Cambridge, UK). Our scientific portfolio from these years (1985-1995) contains hundreds of head injured patients with waveform ICP analysis, introduction of compensatory reserve index RAP, few highly cited papers. Now, we understand ICP much better thanks to David's personal passion and extremely friendly support.

David Stafford-Clark (1916-1999): Seeing through a celebrity psychiatrist.

Science.gov (United States)

Miller, Gavin

2017-04-26

This article uses the mass-media career of the British psychiatrist David Stafford-Clark (1916-1999) as a case study in the exercise of cultural authority by celebrity medical professionals in post-war Britain. Stafford-Clark rose to prominence in the mass media, particularly through his presenting work on medical and related topics for BBC TV and Radio, and was in the vanguard of psychiatrists and physicians who eroded professional edicts on anonymity. At the height of his career, he traded upon his celebrity status, and consequent cultural authority, to deliver mass media sermons on a variety of social, cultural, and political topics. Stafford-Clark tried to preserve his sense of personal and intellectual integrity by clinging to a belief that his authority in the public sphere was ultimately to be vindicated by his literary, intellectual, and spiritual significance. But as his credibility dwindled, he came to distrust the cultural intermediaries, such as broadcasters and publishers, who had supported him.

Full Text Available The American Dream is a recurrent theme in American literature. In this response, this paper is an attempt to expose the destructive effects of the dream on the human spirit. It is also shown, through the analysis of David Mamet’s glengarry Glen Ross, that despite the promise of the dream it contains many contradictions. Beneath the seeming simple surface of the play lies a deep current of meanings that reflect the calamities of modern American life, and in a broader sense, the modern world. This article indicates how capitalism inculcates ideologies in the mind of individuals in order to facilitate the exploiting process and unquestioning subordination. Ragged individualism, for instance, as  the most prominent of these ideologies, disrupts all communal bonds and even exceeds to the disintegration of friendship and family life.

Mind-modelling with corpus stylistics in David Copperfield.

Science.gov (United States)

Stockwell, Peter; Mahlberg, Michaela

2015-05-01

We suggest an innovative approach to literary discourse by using corpus linguistic methods to address research questions from cognitive poetics. In this article, we focus on the way that readers engage in mind-modelling in the process of characterisation. The article sets out our cognitive poetic model of characterisation that emphasises the continuity between literary characterisation and real-life human relationships. The model also aims to deal with the modelling of the author's mind in line with the modelling of the minds of fictional characters. Crucially, our approach to mind-modelling is text-driven. Therefore we are able to employ corpus linguistic techniques systematically to identify textual patterns that function as cues triggering character information. In this article, we explore our understanding of mind-modelling through the characterisation of Mr. Dick from David Copperfield by Charles Dickens. Using the CLiC tool (Corpus Linguistics in Cheshire) developed for the exploration of 19th-century fiction, we investigate the textual traces in non-quotations around this character, in order to draw out the techniques of characterisation other than speech presentation. We show that Mr. Dick is a thematically and authorially significant character in the novel, and we move towards a rigorous account of the reader's modelling of authorial intention.

Full Text Available Dans la Chronique du roi David (1991 , Stefan Heym (1913-2001 propose une perspective favorable sur le potin, nonobstant la censure biblique de cette activité (ex : Proverbe 11:13. La réécriture satirique de Heym de l'histoire biblique se concentre sur le personnage d’Ethan, un écrivain-historien nommé par le roi Salomon pour composer un rapport officiel sur la vie et l’arrivée au pouvoir du roi David. À un moment donné les deux fils d’Ethan, Sem et Sheleph, reviennent du marché et racontent à Ethan certaines rumeurs «savoureuses» qu'ils y ont entendues. Ces rumeurs, tandis qu’elles sont un peu exagérées et embellies, fournissent toutefois des aperçus de la situation politique qui sont beaucoup plus fidèles à la vérité que les inventions des porte-parole officiels. Pour justifier le portrait littéraire de Heym du potin comme une voie pour communiquer la vérité subversive dans les régimes autoritaires, je cite la recherche historique systématique de Robert Darnton au sujet des voies diverses pour communiquer les nouvelles de Paris au dix-huitième siècle (Darnton, 2000. In The King David Report (1972, Stefan Heym (1913-2001 offers a favorable view of gossip, notwithstanding biblical censuring of that activity (e.g. Proverb 11:13.

At one point Ethan's two sons, Shem and Sheleph, come back from the market, telling Ethan of some "juicy" rumors they heard there. These rumors, while using some exaggerations and added embellishments, nevertheless provide insights into the political situation much more faithful to the truth than the fabrications of official spokespersons. To substantiate Heym's literary portrayal of gossip as a channel for communicating subversive truth in authoritarian regimes, I cite Robert Darnton

Full Text Available This article discusses Michael Berkeley’s first opera, Baa Baa Black Sheep: A Jungle Tale. Premiered under the baton of Paul Daniel on July 3rd 1993 at the Cheltenham International Festival of Music, this opera is based on two texts by Rudyard Kipling: The Jungle Books (1894-1895 and “Baa, Baa, Black Sheep” from the short story collection Wee Willie Winkie and Other Stories, first published in 1888. The libretto was penned by the Australian poet, novelist, playwright and librettist, David Malouf. After a brief survey of some of the earliest transpositions of The Jungle Books, I analyse the way David Malouf deals with both texts. “Baa Baa Black Sheep” is used as the central element of his libretto, and episodes and characters from The Jungle Books are incorporated to draw parallelism between the main topics of the two texts. Both Malouf’s endeavour and Berkeley’s, through the music, aims at deconstructing the preposterous oldest transpositions of The Jungle Books and at focusing on the key elements of Kipling’s famous book, notably identity and hybridism, two important themes of colonial and postcolonial literature. The aim of David Malouf and Michael Berkeley is to address an adult audience and show that The Jungle Books are not only aimed at children as Disney’s or Baden Powell’s appropriations of the work could wrongly make us believe.Cet article porte sur Baa Baa Black Sheep: A Jungle Tale, le premier opéra de Michael Berkeley.

In 1759 Johann David Michaelis won a prize from the Prussian Royal Academy for his essay Beantwortung der Frage von dem Einfluss der Meinungen in die Sprache, und der sprache in die Meinungen. The essay was published in the following year and translated into French in 1762, into English in 1769, and into Dutch in 1771. The work has two major themes--linguistic relativity and language change--with ancillary discussions of language in general and of homonymy. Its most significant contribution to the theory of language is its discussion of linguistic relativity, especially in its manifestations in the influence of language on thought. Given the intellectual milieu of the work where inquiry was centered on the origin of language and language universals, it stands as one of the few discussions of this topic and it is also one of the most fruitful discussions of linguistic relativity for any period of history.

Fairness and Respect in Obesity Prevention Policies: A Response to David Buchanan

Directory of Open Access Journals (Sweden)

Katherine King

2014-01-01

Full Text Available In his response to our article (1,2, David Buchanan introduces some useful and important distinctions in the concepts of equality and autonomy. He highlights, for example, the distinction between inequality and inequity, which captures the insight that not all differences between people are unjust. Unjust inequalities are a subset of differences between people, and theories of justice can be defined by how they determine which of these differences are unjust. In addition, he points out that autonomy is not simply a matter of negative liberty, but also about a positive capacity to act. This understanding of autonomy is consistent with the account we offered in the paper, which underlines the importance of both the capacity to understand available options, and the capacity to act on the choices that one makes.

David Barker: the revolution that anticipates existence

Directory of Open Access Journals (Sweden)

Italo Farnetani

2014-01-01

Full Text Available David Barker is the man who “anticipated" the existence of babies by focusing attention on the importance of the fetus and what takes place during intrauterine life. Barker was one of the physicians who in the last decades brought about the greatest changes in medicine, changes so important as to represent a veritable revolution in medical thought. According to Barker's studies, the embryo obviously has a genetic complement coming from the mother and father, but from the very first stages of development it begins to undergo the influence of the outside environment, just as occurs for adults whose biological, psychological and pathological aspects are influenced by the environment to a not well-established percentage between genetic complement and epigenetics. Much of our future lives as adults is decided in our mothers' wombs. If Barker's discovery was revolutionary from the cultural standpoint, it was even more so from the strictly medical one. Barker's research method was rigid from the methodological standpoint, but innovative and speculative in its working hypotheses, with a humanistic slant. Barker's idea has another practical corollary: it is evident that the role of obstetricians, perinatologists and neonatologists is more and more relevant in medicine and future prevention. Unquestionably, besides the enormous merits of his clinical research, among the benefits that Barker has contributed there is that of having helped us to see things from new points of view. Not only is the neonate (and even more so the fetus not an adult of reduced proportions, but perhaps the neonate is the "father" of the adult person.

Comments on the Lambert case: the rulings of the French Conseil d'État and the European Court of Human Rights.

Veshi, Denard

2017-06-01

This study examines the decisions of the French Conseil d'Etat (Supreme Administrative Court) and the European Court of Human Rights in the Lambert case concerning the withdrawal of life-sustaining treatments. After presenting the facts of this case, the main legal question will be analyzed from an ethical and medical standpoint. The decisions of the Conseil d'État and then of the European Court of Human Rights are studied from a comparative legal perspective. This commentary focuses on the autonomous will of an unconscious patient and on the judicial interpretation of the right to life as recognized in article 2 of the European Convention on Human Rights. Furthermore, it medically classifies artificial nutrition and hydration (ANH) as a "treatment" which has ethical and legal implications. While the majority of the bioethical community considers ANH a medical treatment, a minority argues that ANH is basic care. This classification is ambiguous and has conflicting legal interpretations. In the conclusion, the author highlights how a French lawmaker in February 2016, finally clarified the status of ANH as a medical treatment which reconciled the different values at stake.

Reconstructing apology: David Cameron's Bloody Sunday apology in the press.

McNeill, Andrew; Lyons, Evanthia; Pehrson, Samuel

2014-12-01

While there is an acknowledgement in apology research that political apologies are highly mediated, the process of mediation itself has lacked scrutiny. This article suggests that the idea of reconstruction helps to understand how apologies are mediated and evaluated. David Cameron's apology for Bloody Sunday is examined to see how he constructs four aspects of apology: social actors, consequences, categorization, and reasons. The reconstruction of those aspects by British, Unionist, and Nationalist press along with reconstructions made by soldiers in an online forum are considered. Data analysis was informed by thematic analysis and discourse analysis which helped to explore key aspects of reconstruction and how elements of Cameron's apology are altered in subsequent mediated forms of the apology. These mediated reconstructions of the apology allowed their authors to evaluate the apology in different ways. Thus, in this article, it is suggested that the evaluation of the apology by different groups is preceded by a reconstruction of it in accordance with rhetorical goals. This illuminates the process of mediation and helps to understand divergent responses to political apologies. © 2013 The British Psychological Society.

Full Text Available The Unshiu mandarin (Citrus unshiu Marc. is the major Citrus crop in Croatia. Limiting factors for longer consumption of Unshiu mandarin are low storage performance and the appearance of chilling injuries during storage. Previous studies indicated that oxidative stress might be involved in cold-induced peel damage of harvested Citrus fruit. The aim of the present study was to investigate peroxidase distribution, isoenzyme pattern and activity in the peel of Unshiu mandarin fruit. Special goal of our study was to investigate the changes of peroxidase activity in respect to two different hot water dipping (HWD treatments (3 min at 48 and 52 °C and two different storage temperatures (1 and 3 °C combined. Peroxidase activity was detected at the border of oil glands, in the peel surface and in the conducting elements positioned in the inner part of the peel. Electrophoretic analysis revealed the presence of two peroxidase isoenzymes. There were no differences in the electrophoretic pattern after the HWD treatments and cold storage. Lowering of both total and specific peroxidase activity was measured in HWD-treated samples in comparison with the control ones. However, it appeared that significant decrease in total peroxidase activity was influenced by the storage temperatures, while the increase in total soluble protein content was influenced by the HWD pretreatment.

Professor Samuel David Gross (1805-1884) is considered as one of the founders of American surgery. He was a skillful surgeon who could excellently perform a lithotomy, an amputation, and a cataract surgery. He introduced many new surgical techniques and designed new surgical and medical instruments. He expertise was not limited to surgery alone; he also published studies concerning internal medicine, pathology, experimental physiology, and pharmacology. His most important treatise was his 2-volume work, A System of Surgery, Pathological, Diagnostic, Therapeutic and Operative (1861), which was a standard reference book in surgery in the United States during the second half of 19th century. Gross received many honors during his life. He was active in the operating room until his death.

Memory, Identity and Desire: A Psychoanalytic Reading of David Lynch’s Mulholland Drive

Directory of Open Access Journals (Sweden)

Murat Akser

2012-12-01

Full Text Available This is a reading of David Mulholland Drive through psychoanalytic approach of Lacan from the perspective of formation of fantasy and shifting identities. Lynch constructs his films consciously choosing his themes from the sub(versive/conscious side of human mind. Previous attempts to read Lynch's films are fixed around the idea that Lynch is using film genres to create postmodern pastiches. Mulholland Drive has been analyzed several times from different approaches ranging from gender (Love, 2004, narratology (Lentzner, 2005; McGowan, 2004; Cook, 2011. Elements of film noir, musical, caper films can be identified in Lynch’s films. This detailed textual analysis intends to rationalize Lynch’s narrative structure through Lacanian terms in reference to Zizekian terminology.

O texto baseia-se em relatos, documentos, cartas de viajantes, filme e romances de autoria de homens ou mulheres, que visitaram Angerona em épocas diferentes. Ao contrário do filme “Roble de Olor” (2003 que festeja a relação amorosa de Cornelio com Ursula, o autor se interessa pela reconstrução da vida do imigrante e da fazenda, cujas ruínas transformadas em monumento nacional pelo Patrimônio Histórico cubano. Com efeito, a descrição minuciosa de diversos aspectos da fazenda, da casa do senhor e de sua relação com os escravos, não tem outro objetivo senão evidenciar o quanto o humanismo rígido de Cornélio e seu calculo racional contribuíram para a maior eficiência do sistema de dominação da fazenda.

Influence of cutaneous and muscular circulation on spatially resolved versus standard Beer-Lambert near-infrared spectroscopy.

Messere, Alessandro; Roatta, Silvestro

2013-12-01

The potential interference of cutaneous circulation on muscle blood volume and oxygenation monitoring by near-infrared spectroscopy (NIRS) remains an important limitation of this technique. Spatially resolved spectroscopy (SRS) was reported to minimize the contribution of superficial tissue layers in cerebral monitoring but this characteristic has never been documented in muscle tissue monitoring. This study aims to compare SRS with the standard Beer-Lambert (BL) technique in detecting blood volume changes selectively induced in muscle and skin. In 16 healthy subjects, the biceps brachii was investigated during isometric elbow flexion at 70% of the maximum voluntary contractions lasting 10 sec, performed before and after exposure of the upper arm to warm air flow. From probes applied over the muscle belly the following variables were recorded: total hemoglobin index (THI, SRS-based), total hemoglobin concentration (tHb, BL-based), tissue oxygenation index (TOI, SRS-based), and skin blood flow (SBF), using laser Doppler flowmetry. Blood volume indices exhibited similar changes during muscle contraction but only tHb significantly increased during warming (+5.2 ± 0.7 μmol/L·cm, an effect comparable to the increase occurring in postcontraction hyperemia), accompanying a 10-fold increase in SBF. Contraction-induced changes in tHb and THI were not substantially affected by warming, although the tHb tracing was shifted upward by (5.2 ± 3.5 μmol/L·cm, P < 0.01). TOI was not affected by cutaneous warming. In conclusion, SRS appears to effectively reject interference by SBF in both muscle blood volume and oxygenation monitoring. Instead, BL-based parameters should be interpreted with caution, whenever changes in cutaneous perfusion cannot be excluded.

Animals and nature: mapping storylines and metaphors in David Kramer’s narratives

Directory of Open Access Journals (Sweden)

M. Slabbert

2011-06-01

Full Text Available This article discusses the representation of animals and nature in selected lyrics from the oeuvre of singer, songwriter and producer David Kramer and considers his engagement with historical and contemporary discourses about human-animal and human-nature interaction in relation to ecological awareness within a South African context. I trace the socio-political commentary voiced through his depiction of animals in the folksongs he wrote during apartheid, especially in lyrics from the album “Baboondogs” (Kramer, 1986. Kramer also employs intertextual references to traditional South African folksongs and tales in his music. Furthermore, the social and environmental significance of Kramer’s representations of nature in a selection of his postapartheid lyrics is investigated. I argue that the pedagogical value of Kramer’s cultural commentary can contribute significantly to the challenge of teaching animal studies and ecocriticism in South African context.

The moral status of the embryo: an attempt at an analysis with the aid of David Hume's ethics.

Engel, J B; Hönig, A; Segerer, S; Häusler, S F M; Dietl, J; Djakovic, A

2010-12-01

This article applies the moral sentimentalism founded by David Hume to the moral status of the embryo. It will attempt to explain the paradoxical fact that in Germany abortion is common and socially accepted while preimplantation genetic diagnosis is banned with the aid of an approach based on moral sentimentalism. David Hume established the thesis that the human being is guided by the emotions and not by reason when making moral decisions. Scientific innovations often create a feeling of anxiety. Consequently, the initial moral judgment about it is negative. Due to this habit, the innovation is often accepted after a phase of indifference. This phenomenon has been observed in the case of heart transplantation, as well as for IVF. Consequently, the apparent contradiction in the varying degrees of the embryo's worthiness of protection in the womb and in the Petri dish is due to the simple fact that these are different stages of habituation. Therefore, the ethics of Hume cannot stipulate the embryo's moral status for once and for all; however, they can paradoxically raise the ongoing current debate to a more rational level through the insight that the underlying moral concepts are not based on reason alone.

Decay of Ethics in David Mamet’s American Buffalo

2013-09-01

Full Text Available The American Dream is a recurrent theme in American literature. In this response, this paper is an attempt to expose the destructive effects of the dream on human spirits and relations and how it is contradicted in different ways through the analysis of his brilliant play, American Buffalo by David Mamet. Beneath the seeming simple surface of the play lies a deep current of meanings that reflect the calamities of modern American life, and in a broader sense, the modern world. This article indicates how capitalism inculcates ideologies in the mind of individuals in order to facilitate the exploiting process and unquestioning subordination. Ragged individualism, as one of these ideologies, disrupts all communal bonds and even exceeds to the disintegration of friendship and family life. On the other hand, this individualism, as an ideology, is sustained by other capitalist ideologies such as advertising, consumerism and emulation. It will also be discussed that monetary interests are all one seeks in a highly competitive atmosphere and nothing is privileged over business ethics. In brief, this reading of the play tries to illuminate that we live in a dream-like world of ideologies that block logical thinking and forge our relationship with our real existence through less suspected ways.

“Silencio”: hearing loss in David Lynch's Mulholland Drive

Directory of Open Access Journals (Sweden)

Allister Mactaggart

2014-11-01

Full Text Available In a filmmaking career replete with extraordinary images and sounds, David Lynch's Mulholland Drive (2001 stands out for attention as a striking and seemingly inexhaustible resource for analysis. In this article, this film is used to examine the specific ways in which Lynch uses pre-existing pop songs to wrap the spectator within the filmic soundscape. Nowhere is the complexity and uncanniness of pop music made more explicit than in Rebekah Del Rio's stunning performance of “Llorando (Crying” in the Club Silencio scene. The split between the singer's powerful performance and her subsequent collapse with the sound of the voice left hanging in the air marks a pivotal point in the film. This scene, coupled with other examples of feminine jouissance, is contrasted with the deadening roar of the master's voice, which solely demands obedience but is deaf to any reply. At the core of this article is an analysis of the status of the voice (and the gaze as examples of the Lacanian object a and its relationship to Marx's concept of surplus value. Mulholland Drive provides a powerful demonstration of how these concepts can be seen, heard, and felt in relation to film, and how sound can reverberate into the spaces and silences beyond the screen.

A novel HURRAH protocol reveals high numbers of monomorphic MHC class II loci and two asymmetric multi-locus haplotypes in the Père David's deer.

Directory of Open Access Journals (Sweden)

Qiu-Hong Wan

Full Text Available The Père David's deer is a highly inbred, but recovered, species, making it interesting to consider their adaptive molecular evolution from an immunological perspective. Prior to this study, genomic sequencing was the only method for isolating all functional MHC genes within a certain species. Here, we report a novel protocol for isolating MHC class II loci from a species, and its use to investigate the adaptive evolution of this endangered deer at the level of multi-locus haplotypes. This protocol was designated "HURRAH" based on its various steps and used to estimate the total number of MHC class II loci. We confirmed the validity of this novel protocol in the giant panda and then used it to examine the Père David's deer. Our results revealed that the Père David's deer possesses nine MHC class II loci and therefore has more functional MHC class II loci than the eight genome-sequenced mammals for which full MHC data are currently available. This could potentially account at least in part for the strong survival ability of this species in the face of severe bottlenecking. The results from the HURRAH protocol also revealed that: (1 All of the identified MHC class II loci were monomorphic at their antigen-binding regions, although DRA was dimorphic at its cytoplasmic tail; and (2 these genes constituted two asymmetric functional MHC class II multi-locus haplotypes: DRA1*01 ∼ DRB1 ∼ DRB3 ∼ DQA1 ∼ DQB2 (H1 and DRA1*02 ∼ DRB2 ∼ DRB4 ∼ DQA2 ∼ DQB1 (H2. The latter finding indicates that the current members of the deer species have lost the powerful ancestral MHC class II haplotypes of nine or more loci, and have instead fixed two relatively weak haplotypes containing five genes. As a result, the Père David's deer are currently at risk for increased susceptibility to infectious pathogens.

Eli Hecksher as a Portrait Maker

Full Text Available Eli Heckscher was not only author of extensive investigations into economic history. He was also skillful in depicting phenomena in small format in encyclopædias, journals and newspapers. This article presents Heckscher as portrait maker of economic scholars. In these portraits—what he emphasized, what he praised, what he criticized—one can discern the stance of the portrait maker himself. Overall, his portraits are permeated by admiration of sharp theoretical analyses and massive economic historical investigations. He admires the founding fathers of political economy, Adam Smith and David Ricardo, stresses continuity in the development of economic thought, praises humble innovators like David Davidson, Knut Wicksell and Alfred Marshall and denounces (what he perceives as pretentious innovators like Gustav Cassel and John Maynard Keynes. He is critical towards economists who attempt to break out of the classical and neoclassical tradition, especially representatives of the German historical school, and what he judges to be a new type of mercantilism, represented by Bertil Ohlin and Keynes. At the same time he appreciates voluminous and solid investigations into economic history, even if performed without theoretical beacons, by scholars like William Cunningham, William Ashley, John Clapham, Marc Bloch, Richard Ehrenberg and Werner Sombart.

Hacking the aesthetic: David Haines and Joyce Hinterding's new ecologies of signal

Directory of Open Access Journals (Sweden)

Andrew Murphie

2012-06-01

Full Text Available Award winning Australian electronic artists David Haines and Joyce Hinterding's installation work is discussed as “signal-work.” Their work reconfigures signal within original assemblages involving subtle audio, high resolution video (both recorded and animated, kilometers of coiled copper wire, antennae or home-built electronics, electrostatic disturbances, the like of very low frequency radiation from the Milky Way, and cross-signal processing. The article develops a context for thinking about the work in terms of Whitehead's process philosophy, as this is relevant to media theory, as well as concepts of plural ecology and ongoing differentiation drawn from Bateson and Guattari. Signal processing is seen as key to all this. The article argues that in Hinterding and Haines’ signal-work new sensations are produced, outside of the normal “syntax” of some models of aesthetic experience. This challenges some aspects of thinking about both aesthetics and political ecology.

Writing a study of psychologist David Boder's 1946 displaced persons (DP) interview project gave me a chance to further document the substantial early response to the Holocaust. This was clearly one important piece of my study, and one that was eminently straightforward. Yet much of the research on Boder's project at the point in time that I carried it out was elliptical, partly because the primary interview materials were coming to light at an astonishing pace, partly because the archive collections were virtually untapped, and partly because of the misconception of Boder and his interview project itself.

Commentary on "Asynchronous Preparation of Tonally Fused Intervals in Polyphonic Music" by David Huron

Directory of Open Access Journals (Sweden)

James Wright

2008-05-01

Full Text Available In his most recent contribution to an important and well-framed series of papers on auditory grouping and the perception of polyphonic music, David Huron seeks further evidence for his working hypothesis that J.S. Bach controls the employment of perfect consonances by desynchronizing their onsets, thereby inhibiting the perceptual fusion of polyphonic voices. However the more novel contribution of the present study would seem to be its demonstration that Bach also regulates the employment of dissonant tones by consistently desynchronizing their onsets. This finding provides the first concrete evidence for Wright and Bregman’s otherwise untested hypothesis that the control and salience of dissonance in polyphonic music are closely related to principles of auditory stream segregation (Wright, 1986; Wright & Bregman, 1987.

The reconstitution of political theory: David Easton, behavioralism, and the long road to system.

Science.gov (United States)

Gunnell, John G

2013-01-01

During the last half of the twentieth century, the concept of system was arguably the most important concept in the theoretical repertoire of the discipline of American political science. Although systems analysis was broadly employed in the behavioral sciences, David Easton's work was particularly influential in the study of politics. This is in part because he attempted to develop a distinct account of the political system that was not theoretically subservient either to general systems theory or to conceptions of the social system such as that advanced by Talcott Parsons. Although a great deal of attention has been devoted to Easton's theory, the origins and evolution of the system concept in his work have not been carefully reconstructed and analyzed. © 2013 Wiley Periodicals, Inc.

Preferential Consideration: Bartleby, Class, and Genocide in David Foster Wallace’s “Consider the Lobster”

Directory of Open Access Journals (Sweden)

Martin Paul Eve

2017-12-01

Full Text Available This article presents the case for reading Herman Melville’s “Bartleby the Scrivener” as a key intertext for David Foster Wallace’s 2004 essay, “Consider the Lobster”. Focusing upon Wallace’s assertion that “it may well be that an ability to form preferences is the decisive criterion for real suffering” the piece reads Wallace’s work through the lenses of capital, class, political aesthetics, ecology, and genocide. Ultimately, though, this article argues that Wallace’s essay ends with ethical stalemate since Wallace is unwilling to commit to a political stance. It is, as I here argue, as though Wallace’s essay would “prefer not to” make an actual decision.

Full Text Available The recent death of David Bowie activated a memorial process which incites to retrace the cultural, social, aesthetic, of costume, fashion and art history of the last forty years. It’s impossible, therefore, not reflect on the mechanisms that led to the creation of he who in the collective imaginary is reductive to consider just a symbol of modern rock.Several books, prestigious magazines and important exhibitions devoted space to the infinite nuances of he who is defined not only icon but also idol, star, legend and myth. These terms have subtle interferences between them as Jean Jacques Wunenburger underlined and all refer to the concept of Mythology. Even if many authors stated the “disappearance of the myth” in the postmodern epoch (Jewett and Lawrence, the myth is one of those phenomena which involves the everyday life, also in the contemporary time.Certainly the ever closer relations between art, mass media and advertisement played a decisive role in restructuring the concept of myth, but didn’t essentially change its meaning. Actually, the mass reproducibility of images, instead of provoking the “fall of aura”, as stated by Walter Benjamin, seems to have increased the "sacred" magnetism of the images.The icon David Bowie is the result of a multifaceted and outstanding personality which involved and influenced every possible contemporary language - fashion, music, theatre, film, performance, video and more recently internet. As always the photographic gaze captured and crystallized over time the different visions making them eternal and “biting” in the meaning which Barthes clarified in his famous book.The intense collaboration with “the man who photographed the Seventies”, the English Mick Rock, produced images intended to write an important piece of the history of contemporary photography. Ziggy Stardust, the character masterfully interpreted and documented by Mick Rock, is the symbol of Bowie’s fascinating ability

Full Text Available Satsuma (Citrus unshiu Marc. is one of the most abundantly produced mandarin varieties of citrus, known for its seedless fruit production and as a breeding parent of citrus. De novo assembly of the heterozygous diploid genome of Satsuma (“Miyagawa Wase” was conducted by a hybrid assembly approach using short-read sequences, three mate-pair libraries, and a long-read sequence of PacBio by the PLATANUS assembler. The assembled sequence, with a total size of 359.7 Mb at the N50 length of 386,404 bp, consisted of 20,876 scaffolds. Pseudomolecules of Satsuma constructed by aligning the scaffolds to three genetic maps showed genome-wide synteny to the genomes of Clementine, pummelo, and sweet orange. Gene prediction by modeling with MAKER-P proposed 29,024 genes and 37,970 mRNA; additionally, gene prediction analysis found candidates for novel genes in several biosynthesis pathways for gibberellin and violaxanthin catabolism. BUSCO scores for the assembled scaffold and predicted transcripts, and another analysis by BAC end sequence mapping indicated the assembled genome consistency was close to those of the haploid Clementine, pummel, and sweet orange genomes. The number of repeat elements and long terminal repeat retrotransposon were comparable to those of the seven citrus genomes; this suggested no significant failure in the assembly at the repeat region. A resequencing application using the assembled sequence confirmed that both kunenbo-A and Satsuma are offsprings of Kishu, and Satsuma is a back-crossed offspring of Kishu. These results illustrated the performance of the hybrid assembly approach and its ability to construct an accurate heterozygous diploid genome.

Herbal liqueurs are alcoholic beverages produced by the maceration or distillation of aromatic and medicinal plants in alcohol, and are also highly valued for their medicinal properties. The process conditions, as well as the number and quantity of the plants employed, will have a great influence on the quality of the liqueur obtained. The aim of this research was to optimize these important variables. A Box-Benhken experimental design was used to evaluate the independent variables: alcohol content, amount of plant and time during the experimental maceration of plants in grape marc distillate. Four plants were assessed, with the main compound of each plant representing the dependent variable evaluated with respect to following the evolution of the maceration process. Bisabolol oxide A in Matricaria recutita L., linalool in Coriander sativum L. and eucalyptol in Eucalyptus globulus Labill. were quantified using a gas chromatography-flame ionization detector. Glycyrrhizic acid in Glycyrrhiza glabra L was determined using a high-performance liquid chromatography-diode array detector. Other dependent variables were also evaluated: total phenolic content, color parameters and consumer preference (i.e. appearance). The experimental designs allowed the selection of the optimal maceration conditions for each parameter, including the preference score of consumers: 70% (v/v) of ethanol, 40 g L -1 plant concentration and a maceration process of 3 weeks. © 2016 Society of Chemical Industry. © 2016 Society of Chemical Industry.

Emotional intelligence as an aspect of general intelligence: what would David Wechsler say?

Science.gov (United States)

Kaufman, A S; Kaufman, J C

2001-09-01

R. D. Roberts, M. Zeidner, and G. Matthews (2001) have carefully examined the controversial issue of whether emotional intelligence (EI) should be classified as an intelligence and whether EI's constructs meet the same psychometric standards as general intelligence's constructs. This article casts their efforts into the framework of both historical and modern IQ-testing theory and research. It details David Wechsler's attempts to integrate EI into his tests and how his conception of a good clinician would be that of an emotionally intelligent clinician. Current theories and research on IQ also have a role in EI beyond what Roberts et al. described, including J. L. Horn's (1989) expanded model and A. R. Luria's (1966) neuropsychological research, and better criteria than the Armed Services Vocational Aptitude Battery should be used in future EI studies. The authors look forward to more research being conducted on EI, particularly in future performance-based assessments.

The Contrasting Soundscapes of Hull and London in David Bowie’s Ziggy Stardust and the Spiders from Mars

In this article I apply the concept of the urban soundscape as developed by Long and Collins (2012) in an analysis of the impact musicians from Hull had on the evolution of David Bowie’s seminal 1972 work The Rise and Fall of Ziggy Stardust and the Spiders from Mars. I argue that the performance of Ziggy Stardust, both on record and on stage, is doubly coded in relation to place and space.

Full Text Available The book Rethinking Social Inquiry, edited by Henry E. BRADY and David COLLIER, is a response to a book by KING, KEOHANE and VERBA (1994 that aimed to introduce quantitative standards to qualitative research. The authors of the book reviewed here criticize many of the suggestions made there because they argue that qualitative research requires other tools. Nevertheless, they agree that the foundations of research design are similar. The book comprises a comprehensive critique of mainstream quantitative techniques, describes a set of qualitative tools for research, and addresses issues of how to combine qualitative and quantitative approaches to maximize analytical leverage. It is an excellent contribution to the methodological debate in the social sciences. URN: urn:nbn:de:0114-fqs0602309

[Recurrent depressive disorder in Caspar David Friedrich. A pathographical approach with operationalized diagnosis].

Science.gov (United States)

Spitzer, C; Dahlenburg, B; Freyberger, H J

2006-07-01

Caspar David Friedrich (1774 - 1840) is one of the most important German Romantic painters. In his paintings, he prototypically represents the melancholy, which has been mentioned by his contemporaries and later biographers. Art scientists have also referred to his melancholy for the interpretation of his work. From a medical point of view, there are only two pathographies which remain inconclusive. Having applied diagnostic criteria for psychiatric disorders to his letters and publications, to statements of his contemporaries and to his art, we propose that he had suffered from a recurrent major depression which occurred in 1799 for the first time. At least three depressive episodes followed before he was struck by a stroke in 1835. There are epidemiological, psychodynamic and personality-typological reasons supporting our diagnostic assumption. The course of his depression corresponds to phases of reduced creativity, to the chosen techniques and motives. Finally we discuss the implications of our approach for the pathographical method in general.

The David aortic valve-sparing reimplantation (AVr-D) operation is increasingly being used in patients with aortic root aneurysmal disease and pliable aortic cusps. The objective of this study was to assess our early and medium-term outcomes with the AVr-D operation. Between 2003 and 2011, a total of 179 patients underwent AVr-D procedures. The mean patient age was 49.7 ± 15.1 years, and 23.5% (n = 42) were females. Marfan syndrome was present in 17.3% of patients (n = 31), and acute Type A aortic dissection in 15.6% (n = 28). Clinical follow-up was 100% complete and was 1.8 ± 1.6 years (0 days to 7.5 years) long. Echocardiographic follow-up was performed 2.2 ± 1.5 years (0 days to 7.5 years) postoperatively and was 77% complete. Early mortality was 1.1% (n = 2), with both deaths occurring in patients with Type A dissection. Pre-discharge echocardiography revealed no patients with >2+ aortic insufficiency (AI), 19.6% of patients (n = 34) with 1+ or 2+ AI and 80.4% of patients (n = 145) with trace or no AI. Left ventricular end-diastolic diameters decreased significantly from 5.6 ± 0.9 to 5.1 ± 0.8 cm early postoperatively (P valve re-replacement during follow-up, two due to early endocarditis and two due to non-coronary leaflet prolapse in Marfan patients. Five-year freedom from aortic valve reoperation was 95.9 ± 2.0%. AVr-D is associated with a low mortality and morbidity rate, even in patients with Type A aortic dissection. Although a slightly higher rate of recurrent AI may be present in patients with Marfan syndrome, freedom from recurrent AI and reoperation remains excellent during medium-term follow-up. The David operation should be considered the gold standard for patients with proximal aortic root pathology (aneurysm or dissection) and pliable aortic cusps.

Sir David Brewster's changing ideas on the plurality of worlds

Science.gov (United States)

de Asúa, Miguel

2006-06-01

In the course of his long life the Scottish physicist David Brewster wrote copiously about the plurality of worlds. More Worlds than One (1854), perhaps his strongest statement on the question, was written as an answer to William Whewell's On the Plurality of Worlds (1853), which argued that life was a privilege of the Earth. Brewster's ideas changed drastically along the years in many crucial issues such as the habitability of the Sun and the Moon, the possibility that extraterrestrials could be different from humans, and the occupation of the Earth by intelligent races in the distant past. This paper succinctly surveys Brewster's main lines of thought about the plurality of worlds underlining the significance of his first two articles devoted exclusively to this topic. They were published in 1838 in The Monthly Chronicle, and affirm the habitability of the planets while denying that of the Moon. As is the case with many Victorian scientists, belief in pluralism was for Brewster part and parcel of a complex of ideas and attitudes in which it is hard to distinguish science from religion. I shall argue that a fair number of the shifting opinions and inconsistencies detectable in Brewster's ideas on the plurality of worlds can be attributed to the fact that these were used as pliable apologetic instruments in his scientific writings, many of which are permeated by strong religious concerns.

Full Text Available O objetivo deste artigo é fundamentar a escolha pela perspectiva teórica do materialismo histórico-geográfico, desenvolvida pelo geógrafo David Harvey para compreender uma região. Para tanto, apresentamos e discutimos também os referenciais predominantes nas análises sobre regiões, com o intuito de demonstrar os limites desses referenciais e as possibilidades abertas pela perspectiva de Harvey. Assim, apresentamos alguns dos principais conceitos que têm orientado as ações de governos dos mais diversos matizes; a abordagem de David Harvey bem como seus pressupostos teóricos e históricos; e uma análise comparativa em que demonstramos as limitações dos referenciais predominantes e as possibilidades da perspectiva do último autor. Ao final, conclui-se que o materialismo histórico-geográfico permite compreender que as dinâmicas sociais e econômicas de uma região se caracterizam em processos conflituosos e contraditórios e resultam em uma configuração regional específica e transitória.

Simultaneous determination of sample thickness, tilt, and electron mean free path using tomographic tilt images based on Beer-Lambert law.

Cryo-electron tomography (cryo-ET) is an emerging technique that can elucidate the architecture of macromolecular complexes and cellular ultrastructure in a near-native state. Some important sample parameters, such as thickness and tilt, are needed for 3-D reconstruction. However, these parameters can currently only be determined using trial 3-D reconstructions. Accurate electron mean free path plays a significant role in modeling image formation process essential for simulation of electron microscopy images and model-based iterative 3-D reconstruction methods; however, their values are voltage and sample dependent and have only been experimentally measured for a limited number of sample conditions. Here, we report a computational method, tomoThickness, based on the Beer-Lambert law, to simultaneously determine the sample thickness, tilt and electron inelastic mean free path by solving an overdetermined nonlinear least square optimization problem utilizing the strong constraints of tilt relationships. The method has been extensively tested with both stained and cryo datasets. The fitted electron mean free paths are consistent with reported experimental measurements. The accurate thickness estimation eliminates the need for a generous assignment of Z-dimension size of the tomogram. Interestingly, we have also found that nearly all samples are a few degrees tilted relative to the electron beam. Compensation of the intrinsic sample tilt can result in horizontal structure and reduced Z-dimension of tomograms. Our fast, pre-reconstruction method can thus provide important sample parameters that can help improve performance of tomographic reconstruction of a wide range of samples.

Last Words: David's Mars Disarmed by Venus and the Graces (1824. Subjectivity, Death, and Postrevolutionary Late Style

Directory of Open Access Journals (Sweden)

Padiyar, Satish

2011-06-01

Full Text Available Completed as he was approaching death in 1825, Jacques-Louis David's final refractory history painting is an intricate summation of a life in politics and painting. The article attempts to re-interpret the canvas in relation to the dual problem of 'late style' and the condition of exile. I argue that this history painting invokes the metaphor of non-sex for the condition of exile; and as a late gesture stages an anomalous return to a pre-lapsarian eighteenth century. The painting, I conclude, reveals less the transcendent subjectivity of an artist approaching biological death, than the critical disarming of a once-radical neoclassical aesthetic itself, in its tragic late phase.

Theory of Money of David Ricardo: Quantity Theory and Theory of Value

Directory of Open Access Journals (Sweden)

Susumu Takenaga

2003-01-01

Full Text Available En lo que es necesario enfatizar, al caracterizar la teoría cuantitativa de David Ricardo, es en que ésta es una teoría de determinación del valor del dinero en una situación particular en la cual se impide que el dinero, sin importar cual sea su forma, entre y salga libremente de la circulación. Para Ricardo, la regulación del valor del dinero por su cantidad es un caso particular en el cual el ajuste del precio de mercado al precio natural requiere un largo periodo de tiempo. La determinación cuantitativa es completamente inadmisible, pero solo cuando el período de observación es más corto que el de ajuste. En todo caso, la determinación del valor del dinero rara vez es vinculada a su teoría del valor de las mercancías. Contrario a la interpretación aceptada comúnmente, Ricardo no aplicó a la determinación del valor del dinero una teoría del valor distinta de aquélla aplicada a las mercancías en general.

El enigma de las montañas reales: propuesta narrativa de David Toscana

Directory of Open Access Journals (Sweden)

Iwona Kasperska

2013-01-01

Full Text Available The objective of this paper is to reflect on some features of David Toscana’s novel Los puentes de Königsberg. In this contribution by the Northern Mexican writer there are unusual parallelisms between different realities of the cities of Monterrey (Mexico and Königsberg (East Prussia, which become the basis of the structure of the novel. In this framework the author situates certain eccentric characters, providing them with a “double life”, a real Mexican one and an imaginary East-Prussian one, in order to contrast the cities and validate the superiority of Königsberg, the actual protagonist of the novel. Toscana uses selected criteria, such as scientific and cultural contributions by the cities, their different historical fates, and the moral attitudes of their inhabitants towards discrimination, war crimes and gender violence, which implies a severe critique of Monterrey’s society. The set of parallelisms between the cities is totally convincing as a fictional structure and emphasizes the most prominent quality of Toscana’s analysed prose.

Full Text Available Travel and cultural exchange between the United Kingdom and the United States of America became a key feature of the 1960s, shaping the world view of many a British artist, curator, architect, writer, film-maker, and academic. Against that wider backdrop, I offer here a focused reading of David Hockney’s 1965 painting, Rocky Mountains and Tired Indians. With its faux-naive idiom and overt but quirkily un-modern American theme, the work conveys the artist’s singular take on what it felt like to be a Brit at large in the US, an environment at once wondrously exotic and at times strikingly banal. Close analysis discloses Hockney’s rich repertoire of artistic and literary allusions in Rocky Mountains, and the meanings and associations these may have encapsulated.

Full Text Available Este texto tem por objetivo ressaltar um aspecto que não tem sido tratado com a devida profundidade na literatura que estuda a formalização da Teoria Geral do Emprego, dos Juros e da Moeda de John Maynard Keynes (1936. Mais precisamente, o texto destaca a estratégia de formalização adotada por David G. Champernowne em seu artigo intitulado "Unemployment, Basic and Monetary: the classical analysis and the keynesian", publicado em 1935-36 na Review of Economic Studies. Chamamos a atenção para o fato dele distinguir a teoria clássica da teoria de Keynes não apenas pelos pressupostos adotados por cada teoria, mas principalmente pela construção de subsistemas a partir de um sistema geral, com características recursivas (relações de causalidade distintas. As explicações "em prosa", a descrição algébrica das funções comportamentais e condições de equilíbrio e a ilustração por meio de diagramas, além da escolha de conjuntos específicos de variáveis para representar cada uma das teorias e suas diferentes versões são aspectos deste artigo de Champernowne que merecem uma análise mais minuciosa.

Quantum mechanics in the cold war; Quantenmechanik im Kalten Krieg. David Bohm und Richard Feynman

Energy Technology Data Exchange (ETDEWEB)

Forstner, C.

2007-07-01

In the middle of the 20th century David Bohm and Richard Feynman developed two fundamentally different approaches of modern quantum mechanics: Bohm a realistic interpretation by means of hidden parameters and Feynman the path-integral formalism. This is by this more remarakable, because both physicists started from similar conditions and originated from similar connections. By its comparing approach this study presents more than a contribution to the history of the quantum theory. By the question for the social and cultural conditions of the formation of theories it is furthermore of science-sociological and science-theoretical interest. The in the beginning similar and later different binding of both scientists into the scientific community allows furthermore to study, which adapting pressure each group puts on the individual scientist and the fundamental parts of his research, and which new degrees of freedom in the formation of theories arise, when this constraint is cancelled.

2nd Ralf Yorque Workshop

These are the proceedings of the Second R. Yorque Workshop on Resource Management which took place in Ashland, Oregon on July 23-25, 1984. The purpose of the workshop is to provide an informal atmosphere for the discussion of resource assessment and management problems. Each participant presented a one hour morning talk; afternoons were reserved for informal chatting. The workshop was successful in stimulating ideas and interaction. The papers by R. Deriso, R. Hilborn and C. Walters all address the same basic issue, so they are lumped together. Other than that, the order to the papers in this volume was determined in the same fashion as the order of speakers during the workshop -- by random draw.

Obituary: David Q. Wark, 1918-2002

2003-12-01

David Q. Wark, a research meteorologist at the National Environmental Satellite, Data, and Information Service of the National Oceanic and Atmospheric Administration (NOAA/NESDIS) and its predecessor organizations for 55 years, died of cancer 30 July 2002. He will be long remembered for his seminal contributions to the weather satellite program. A pioneer in the use of satellite sensors to provide observations of the Earth's environment for application to weather forecasting and atmospheric science, Dr. Wark was noted for his brilliant insights, dedication, and exceptional scientific achievements. He developed many of the theoretical and experimental techniques on which NOAA's current multi- billion-dollar meteorological satellite program is based. In the 1960's and early 1970's, he and his NOAA colleague Donald Hilleary were the motivating force and principal investigators for the first satellite instruments dedicated to sounding the atmosphere for temperature and water-vapor. These instruments included the Satellite Infra-Red Spectrometer (SIRS)-A and -B and the Vertical Temperature Profile Radiometer (VTPR), which were flown on NASA's Nimbus satellites and NOAA's ITOS-D satellites, respectively. With colleague Henry Fleming, he formulated the radiative transfer equation that quantifies the spectral radiances of the Earth and its atmosphere (measured at satellite altitude) and inverted that equation mathematically to infer the atmospheric temperature profile from satellite-based measurements of those radiances. A difficulty they had to overcome was that the mathematical problem is ill-posed, i.e., it admits of an infinite number of solutions. They arrived at a unique solution via an innovative application of a-priori information on the atmospheric state. This work was described in the landmark 1965 Wark and Fleming paper in the American Meteorological Society's Monthly Weather Review. From that early period until just weeks before his death, Dr. Wark continued

This study sought to compare the diagnostic accuracy of visual and quantitative analyses of myocardial perfusion cardiovascular magnetic resonance against a reference standard of quantitative coronary angiography. Visual analysis of perfusion cardiovascular magnetic resonance studies for assessing myocardial perfusion has been shown to have high diagnostic accuracy for coronary artery disease. However, only a few small studies have assessed the diagnostic accuracy of quantitative myocardial perfusion. This retrospective study included 128 patients randomly selected from the CE-MARC (Clinical Evaluation of Magnetic Resonance Imaging in Coronary Heart Disease) study population such that the distribution of risk factors and disease status was proportionate to the full population. Visual analysis results of cardiovascular magnetic resonance perfusion images, by consensus of 2 expert readers, were taken from the original study reports. Quantitative myocardial blood flow estimates were obtained using Fermi-constrained deconvolution. The reference standard for myocardial ischemia was a quantitative coronary x-ray angiogram stenosis severity of ≥70% diameter in any coronary artery of >2 mm diameter, or ≥50% in the left main stem. Diagnostic performance was calculated using receiver-operating characteristic curve analysis. The area under the curve for visual analysis was 0.88 (95% confidence interval: 0.81 to 0.95) with a sensitivity of 81.0% (95% confidence interval: 69.1% to 92.8%) and specificity of 86.0% (95% confidence interval: 78.7% to 93.4%). For quantitative stress myocardial blood flow the area under the curve was 0.89 (95% confidence interval: 0.83 to 0.96) with a sensitivity of 87.5% (95% confidence interval: 77.3% to 97.7%) and specificity of 84.5% (95% confidence interval: 76.8% to 92.3%). There was no statistically significant difference between the diagnostic performance of quantitative and visual analyses (p = 0.72). Incorporating rest myocardial

sufficiently close to any corrugated—and/or any smooth—surface and thus enforce a strong vdW-type adhesion; it exploits what is then essentially a contact force (dominated by the attraction exerted in the near-surface regions) to defy the pull of gravity on its own bulk. This Journal of Physics: Condensed Matter special issue is dedicated to the memory of David C Langreth. David is a dearly missed friend and mentor who inspired many of us. He was an outstanding condensed matter theorist and a scholar who greatly influenced us through his many-particle-physics based insights into density functional theory (DFT), surface science and related areas. His seminal works range from conserving formulations of interacting nonequilibrium transport [1] and formal-scattering theory [2] to an explicit formulation [3] of the exact DFT exchange-correlation energy in the adiabatic connection formula (ACF), the latter also being derived independently by Gunnarsson and Lundqvist [4]. David's portfolio also includes an analysis [5] that helped catalyze and guide the development of DFT from the local-density approximation (LDA) to the formulations of generalized gradient approximations (GGAs). Another salient contribution of David's is in the area of vdW interactions in materials. He was a key architect of the vdW density functional (vdW-DF) method [6, 7]. This method was developed in a long-standing Rutgers-Chalmers collaboration between David's group and that of Bengt I Lundqvist, later extending to a wider group of researchers on both sides of the Atlantic. Plasmons are collective excitations that depend on electron-density variation. The plasmon response can be seen as defining the nature of the LDA [4] and their description can thus also be seen as contributing to the success of GGA. The vdW-DF method is a regular constraint-based density functional (for ground-state DFT) which is derived within the ACF framework and which emphasizes the electrodynamical nature of the coupling between

The marcs of two red grape (V. vinifera L.) varieties (Boğazkere and Oküzgözü), grown in eastern Anatolia (Elazig), were evaluated for their fatty acid composition, and antioxidant and antibacterial activities. The hexane extracts of both varieties were found to contain linoleic, palmitic, stearic and oleic acids by GC-MS analyses. The major fatty acid (linoleic acid) was detected relatively as 57.13% in Oküzgözü and 59.07% in Bogazkere in methylated hexane extracts. In addition, myristic and palmitoleic acids were observed in Boğazkere as minor components. The free radical (DPPH) scavenging activity of Oküzgözü was higher than that of Bogazkere. The IC50 values were calculated as 403.0 +/- 7.8 microg/mL for Oküzgozü and 552.0 +/- 23.6 microg/mL for Bogazkere. The extracts were found to be effective on the four gram (+) and four gram (-) test bacteria, but not as good as standard antibiotic, gentamycine by MIC method.

The possibility of obtaining marketing authorization of orphan pharmaceutical compounding preparations: 3,4-DAP for Lambert-Eaton Myasthenic Syndrome.

Pharmaceutical compounding preparations, produced by (hospital) pharmacies, usually do not have marketing authorization. As a consequence, some of these pharmaceutical compounding preparations can be picked-up by a pharmaceutical company to obtain marketing authorization, often leading to price increases. An example is the 3,4-diaminopyridine slow release (3,4-DAP SR) tablets for Lambert-Eaton Myasthenic Syndrome (LEMS). In 2009 marketing authorization was given for the commercial immediate release phosphate salt of the drug, including a fifty-fold price increase compared to the pharmaceutical compounding preparation. Obtaining marketing authorization for 3,4-DAP SR by academia might have been a solution to prevent this price increase. To determine whether the available data of a pharmaceutical compounding preparation with long-term experience in regular care are adequate to obtain marketing authorization, 3,4-DAP SR is used as a case study. A retrospective qualitative case-study was performed. Initially, document analysis was executed by collecting the required data for marketing authorization in general and whether data of Firdapse® and 3,4-DAP SR met these requirements. Secondly, the (non-) available data of the two formulations were compared with each other to determine the differences in availability. At the time of approval, almost all data were available for both Firdapse® and 3,4-DAP SR. Conversely, much of the data used for the approval of Firdapse® originated from the 3,4-DAP immediate release (3,4-DAP IR) formulation. Only two bioequivalence studies and one pharmacology safety study was performed with Firdapse® before marketing authorization application. In conclusion, at time Firdapse® obtained approval, the data available did not differ substantially from 3,4-DAP SR, indicating that approval with 3,4-DAP SR would have been possible. We make a plea for approval of orphan medicinal products developed and manufactured by academic institutions as to

Full Text Available The pedagogical work with mathematical modeling assumes investigate situations of reality. However, mental models formed from the contact with the experiential world are generally incompatible with the conceptual models. So David Hestenes supports the view that one of the biggest challenges of teaching and learning in science and mathematics is to coordinate conceptual models with mental models, which led to the elaboration of a didactic in mathematical modeling: Modeling Instruction. Our goal is to present a proposal for thematic modeling cycle drawn up in hestenesianos assumptions and discuss possibilities for scientific literacy. The main question was to know how to emerge indicators for scientific literacy for the proposed cycle. This is a bibliographic research in order to identify the available literature contributions on the subject and raise the possibility and challenges for the brazilian teaching science and mathematics. Preliminary results indicate that the proposed modeling cycle can develop indicators for scientific literacy of different natures.
