The use of low‐temperature crystallisation in the determination of component acids of liquid fats. II. Fats which contain linolenic as well as linoleic and oleic acids (1946)

Abstract The mixed fatty acids are first separated into sovorul groups by crystallisation from appropriate solvents at low temperatures. In each group the proportions of linolenic, linoleic, oleiu and saturated acids are determined spectrographically after isomerisation with alkali, 1 Palmitic acid and other saturated acids may be determined by fractional distillation of the completely hydrogenated methyl eaters of the total mixed fatty acids, or from direct ester‐fractionation of the methyl esters of each group of the mixed acids obtained by low temperature crystallization. The accuracy of the determination depends largely on the degree to which, by low temperature crystallisations, the mixed fatty acids are resolved into (i) portions rich in olcic and/or saturated acids (with only minor amounts of linoleic and linolenic acid) and (ii) portions rich in linoleic and/or linolenic acid (with relatively small proportions of oleic and saturated acids). The procedure is illustrated by determination of the component acids of linseed oil, of wheat germ oil, and of two specimens of rubber seed oil. The propects of rubber seed oil as a drying oil for the paint industry are briefly discussed.
Parallelizing a PDE solver: experiences with PISCES-MP (2002)

The paper presents a methodology for adapting dusty deck PDE solvers for parallel execution. Our approach minimizes changes to existing code and data structures, thereby preserving the value captured within dusty decks. This scheme uses the single program multiple data programming paradigm on message passing distributed memory architectures. To demonstrate the viability of our methodology the commercially available, dusty deck semiconductor device modeling program, PISCES, has been adapted for parallel execution. Simulating realistic complex device structures, we have achieved excellent performance gains over high performance serial workstations. Also, the scalability of the parallel simulator allows the simulation of structures too large for our existing serial computers.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
High speed cryogenic operation of sub-micron pseudomorphic InGaAs/GaAs FETs (2002)

Comprehensive DC and high frequency measurements of submicron pseudomorphic AlGaAs/InGaAs MODFETs, InGaAs/GaAs MESFETs, and AlGaAs/InGaAs MISFETs at cryogenic temperatures are discussed. Devices with gate lengths from 0.8 mu m to 0.3 mu m over a temperature range from 300 K to 110 K were measured. Similar variation in the measured extrinsic current gain cutoff frequency, f/sub T/, and similar dependences of the effective electron velocity, V/sub eff/, with reduced lattice temperature for the different field-effect transistors were determined. These results provide direct experimental evidence that the saturated velocity of electrons is the most important parameter for high speed operation, and with proper design these different pseudomorphic InGaAs/GaAs field-effect transistors provide similar potential for high speed operation.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Identifying and Classifying Suspicious Network Behavior Using Passive DNS Analysis (2015)

Global Domain Name System (DNS) traffic provides a unique perspective on domain names usage by both legitimate users and suspicious applications. Beyond conventional DNS analysis queries and responses altogether, in this paper we investigate domain name queries to identify suspicious network traffic at.br country code Top-Level Domain (ccTLD) authoritative name servers. By monitoring and modeling three DNS components into a direct graph, we expect that network operators are able to understand communication patterns between hosts and domain names, and the real purpose for a name resolution such as in mass Spam or in network reconnaissance attacks. This paper identifies relevant hosts for analysis among network traffic, reducing the number entities to be investigated.
Sporulation of Streptomyces Venezuelae in Submerged Cultures (1990)

Shaken cultures of Streptomyces venezuelae ISP5230 in minimal medium with galactose and ammonium sulphate as carbon and nitrogen sources, respectively, showed extensive sporulation after 72 h incubation at 37 degrees C. The spores formed in these cultures resembled aerial spores in their characteristics. The ability of the spores to withstand lysozyme treatment was used to monitor the progress of sporulation in cultures and to determine the physiological requirements for sporulation. In media containing ammonium sulphate as the nitrogen source, galactose was the best of six carbon sources tested. With galactose S. venezuelae ISP5230 sporulated when supplied with any of several nitrogen sources; however, an excess of nitrogen source was inhibitory. In cultures containing galactose and ammonium sulphate, sporulation was suppressed by a peptone supplement. The onset of sporulation was accompanied by a drop in intracellular GTP content. When decoyinine, an inhibitor of GMP synthase, was added to a medium containing starch and ammonium sulphate, a slight increase in sporulation was seen after 2 d. The suppression of sporulation by peptone in liquid or agar cultures was not reversed by addition of decoyinine. A hypersporulating mutant of S. venezuelae ISP5230 was altered in its ability to assimilate sugars. In cultures containing glucose the mutant sporulated more profusely than did the wild-type and did not acidify the medium to the same extent. However, the suppressive effect of glucose on sporulation was not merely a secondary result of acid accumulation.
Guest editor's preface (2002)

4-6 October 2000.The ESORICS symposia have been held every two years since 1990 and represent the main European forum for security research.Several papers presented at the ESORICS 2000 Symposium were invited for submission to the Journal.Submitted papers were revised for journal publication and subjected to the normal rigorous review process of the Journal.This issue contains four papers selected for publication through this process."Manageable access control for CORBA", by Gerald Brose presents a language and its support for specifying and managing access control policies.This language provides a formal notation that allows the security administrators to express a wide range of practical security policies.This language called VPL for View Policy Language is based on the concept of role already widely used in the RBAC model.In this paper, roles have a strictly functional interpretation and groups are used to model organizational structure.VPL also uses the concept of view that is introduced as a grouping concept for providing a more comprehensive specification of access control policies.This paper then shows how to combine these concepts in the context of CORBA.Gerhard Schellhorn and colleagues, in "Verified formal security models for multiapplicative smart cards", present two security models that are extensions of the classical Bell/LaPadula and Biba models.The first model is designed at a very abstract level and the second refines the first by inserting more practical issues that are useful for multiapplicative smart cards.These models include requirements for authentication and intransitive noninterference, and avoid the need for trusted processes that is generally viewed as a drawback of the Bell/LaPadula model.An interesting and useful contribution is that, unlike several theoretical papers on noninterference previously published, this paper describes how to use such a model in developing a practical system."Checking secure interactions of smart card applets: extended version", by Pierre Bieber and colleagues is a paper on a similar topic.In the context of a multiapplicative smart card, this paper shows how to verify that applets interact in a secure way.The suggested security policy is a MAC policy that associates labels to applet attributes and methods.The main contribution is then to define a technique based on model checking to verify that actual information flows between applets are authorized.This approach is illustrated in the context of an electronic purse running on Java Card.
Abstract 106: A Novel Small Molecule Protects Against Myocardial Ischemia and Doxorubicin-Induced Cardiomyopathy Through Heat Shock Response and Proteostasis Regulation In Vivo (2012)

Background: A potentially new non-cell-based therapy is the systemic delivery of small molecules to revive or protect injured myocardium. By screening a drug library, we identified a novel small molecule, sk421, and tested its effectiveness in two myocardial injury models in vivo: a myocardial infarction model and doxorubicin (DOX)-induced cardiomyopathy model. Results: Sk421 significantly increased cellular viability of DOX-injured cardiomyocytes by preventing apoptosis in vitro, demonstrated by assays for MTT (p=0.042), annexin-V, and active caspase-3 (p=0.004). Sk421 increased the concentrations of the GATA4 and the heat shock proteins (HSPs) in cardiomyocytes (by 1.5-fold), and fibroblasts (by 1.2-fold), but was unable to rescue DOX-injured fibroblast cells depleted of HSPs. Sk421 maintained the total proteosome by a 3.5-fold inhibition of ubiquitinized GATA4 degradation, as shown by immunoprecipitation assays. Oral administration of sk421(4mg/kg) rescued DOX-injured mice by significantly preserving cardiac function, weight gain, cardiomyocyte lesion size and abundance, and by reducing overall mortality (20% in treated groups) compared to control DOX-injured mice (80% in untreated groups, p<0.03). The levels of GATA4 and HSPs were increased in the sk421-rescued mice. In the MI model, (n=5/group), sk421 reduced myocardial infarct size, and protected heart function evaluated by ejection fraction 45.8 ± 2.4 vs. 34.8 ± 3.3, p=0.005 (day7), and 44.3 ± 2.8 vs. 34.4 ± 4.1, p=0.011 (day28). Sk421 treatment of MI rats resulted in a higher fraction of viable tissue (within the LV (70.20 ± 0.5024, n=3) as compared to only MI group (56.38 ± 3.879%, n=3) and the infiltration of CD68+ cells was found to be more in the infarct region of LV of MI group rats as compared to MI+CEL. Quantitative analysis showed a significantly higher proportion of TUNEL positive cells and mRNA levels of IL-1β, IL-6, TNF-α and MMP2 in the myocardium of MI rats compared to MI+SK421 rats. Conclusion: This study demonstrates the broad therapeutic benefit of sk421 in animal model of myocardial injury by mechanism of inducing the heat shock response and preserving GATA levels. The ease of oral delivery makes sk421 a potentially clinically useful adjunct for myocardial preservation.

Representation of Spectral Profiles in the Auditory System. Part 1. Detection of Spectral Peak Shapes and Ripple Phases (1992)

Abstract : This paper explores the question of how spectral profiles are represented in the auditory system. Using profile analysis methods, listeners' sensitivities to changes in spectral peak shapes and ripple phases were measured. Peak shapes were uniquely described in terms of two parameters: a symmetry factor (SF) which roughly measures the local evenness or oddness of a peak, and a bandwidth factor (BWF) which reflects the tuning or sharpness of a peak. Thresholds to changes in these parameters (defined as delta-SF and delta-BWF/BWF) were measured together with the effects of several manipulations such as using different peak levels, varying spectral component densities, and randomizing the frequencies of the peaks. The basic result that emerges is that delta-SF and delta-BWF/BWF thresholds are largely constant regardless of the standard's peak shape. The only exception occurs for the narrowest peaks (smallest BWF's) where delta-SF thresholds rise. A fundamental conclusion arising from these data is that peak profiles are represented along two sensitive and largely independent axes: peak bandwidth and symmetry factors. More generally, it is conjectured that for an arbitrary spectral profile these two axes correspond to the magnitude and phase of a Fourier transformation of the profile. In this light, the last set of experiments measured listeners' sensitivity to ripple phase changes in sinusoidal ripple stimuli. The thresholds obtained are similar in value and trends to delta-SF thresholds.
An analysis of the probability distributions of charge in electrical trees generated by needle tests (2002)

The problem of the stochastic description of the time to tree growth in insulation systems is addressed in this paper. Resorting to tests performed by the classic needle-plane configuration, it is shown that, depending on the amplitude of applied voltage and the growth time, data fit well either a two-parameter or a five-parameter Weibull function, but the former can be considered as the most representative of the investigated phenomenon. The values of the parameters of the Weibull function are connected with the shape of the tree, as well as its time evolution and applied electrical field, thus providing a useful tool for insulation characterization.
H NMR Imaging and Spectroscopy Studies of the Polymerization of Acrylamide Gels (1996)

1H nuclear magnetic resonance spectra and images have been acquired during polymerization of a mixture of soluble reactive methacrylamide (monomer) and N,N‘-methylenebisacrylamide (cross-linking molecule). The mixture was polymerized by adding ammonium persulfate (initiator) and tetramethylethylenediamine (accelerator) to form long-chain, cross-linked polymers. Study of the time-varying spin−lattice relaxation times (T1) during the polymerization was conducted at 25 and 35 °C and the variation of spectra and T1 with respect to the extent of polymerization was determined. To verify homogeneous polymerization, multidimensional 1H NMR imaging was utilized for in-situ monitoring of the process. The intensities from the images are modeled and the correspondence shows a direct extraction of T1 data from the images.

Disinfection of Wastewater Effluents with Electron Radiation (1989)

A full scale electron irradiation unit is being tested at the Virginia Key Wastewater Treatment Plant in Miami, Florida. On-going experimentation is evaluating the use of high energy electrons for treatment of water wastewater and hazardous wastestreams at a flow of 120 gallons per minute. The electron irradiator used in this study is a 1.5 Mev Insulated Core Transformer electron accelerator. Preliminary testing has focused on secondary effluent, both chlorinated and unchlorinated, from the treatment plant in Miami, Florida. Measurements have been made to define bacterial inactivation. It has been seen that the degree of inactivation of indicator microorganisms is a function of applied dose, and approximately four logs of inactivation have been measured at a dose of approximately 600 kilorads.

UPTAKE BY AND FATE OF LYSOZYME IN ROOTS OF IASIONE MONTANA (CAMPANULACEAE) (1974)

A basic protein, lysozyme, labeled with fluorescein isothiocyanate, is readily taken up by roots of lasione montana. Most of the protein taken up is tightly bound to cell walls of the roots. Fluorescent protein is diluted in the growing region of a root as cells elongate and divide. Fluorescence remains in mature nongrowing regions and root cap cells for one to two weeks. Redistribution and translocation of the protein within the root is minimal or nil. A layer of chloroform‐soluble material that prevents lysozyme from interacting with stem cell walls exposed to fluorescent lysozyme was found on stems of germinating Iasione montana.
Characteristics of diodes prepared using epitaxial CoSi2 as a boron diffusion source (2000)

The effect of formation temperature of epitaxial CoSi2 in the Co/Ti/Si system on electrical characteristics of a p+n junction diode has been investigated. When the silicide formation temperature was 800 °C, a very low reverse leakage current density of 11 nA/cm2 at a bias of −5 V was obtained. However, when the temperature was 900 °C, the reverse leakage current was increased by more than three orders of magnitude. This was attributed to the formation of a Ti-rich phase at the surface by the reaction between the Co–Ti–Si phase and CoSi2 at 900 °C. The Ti-rich phase acted as a dopant sink, and suppressed the diffusion of boron to the CoSi2/Si interface. This caused very shallow junction depth with a low boron concentration at the region directly below the Ti-rich phase, followed by generation of a large reverse leakage current.
Incidence of Perioperative Myocardial Ischemia Detected by Different Electrocardiographic Systems (1990)

To determine the extent to which different electrocardiographic systems account for differences in reported incidence of perioperative myocardial ischemia, the authors simultaneously recorded in 109 patients undergoing coronary artery bypass grafting (CABG) the V5 or modified CM5 lead on five ECG systems by means of a specially constructed common V5 lead. The systems included a Spacelabs Alpha 14 Model Series 3200 ECG Cardule at bandwidths of 0.05-125 Hz and 0.5-30 Hz (a typical operating room monitor), a Marquette Electronics MAC II ECG at 0.05-40 Hz and 0.05-100 Hz (a standard ECG), and a Del Mar Holter recorder at 0.1-100 Hz. Relative ST-segment position and incidence of new ischemia compared to the preoperative ECG were determined in 109 sets of preinduction traces and 877 sets of intraoperative traces. ST-segment position on the three recording systems conforming with the American Heart Association (AHA) low-frequency response recommendations (0.05 Hz) were similar. Compared to the standard ECG, ST-segment position on the Spacelabs at 0.5-30 Hz was consistently more negative. Displacement on the Holter was consistently less negative and less positive. By the 0.1-mV displacement criterion for diagnosis of myocardial ischemia on any one ECG system, 16.5% of patients on arrival and 32.1% of patients intraoperatively suffered new myocardial ischemia. Based on the operating room monitor, arrival and intraoperative ischemia were present in 15.6 and 27.5% of patients, respectively. Ischemia at the same periods was less frequent by the standard ECG system (5.5 and 12.8%, respectively) and least frequent by the Holter recorder (4.6 and 8.3%, respectively).(ABSTRACT TRUNCATED AT 250 WORDS)

Measurement and Evaluation of Noise and Discomfort (1968)

<div class="htmlview paragraph">The engineer is often faced with the problem of forecasting the effects on human beings of the sound produced by equipment operating within the environment in which they live or work. A detailed measurement of sound pressure levels throughout the frequency spectrum is necessary for a complete analysis, but the standard sound level meter is probably adequate for most purposes and nearly as accurate as more complex computations. This paper provides useful criteria for specifying performance of equipment or for limiting the exposure of human beings to noise in certain acoustical environments.</div>

Studies on the sites in histones phosphorylated by adenosine 3':5'-monophosphate-dependent and guanosine 3':5'-monophosphate-dependent protein kinases. (1976)

Adenosine 3':5'-monophosphate-dependent protein kinase (protein kinase A) purified from silkworm pupae phosphorylated five major fractions of calf thymus histone, whereas guanosine 3':5'-monophosphate-dependent protein kinase (protein kinase G) purified from the same organism reacted preferentially with H1, H2A, and H2B histones. Amino acid analysis of the phosphopeptides which were obtained by proteolytic digestion revealed that both protein kinases A and G showed the abilities to phosphorylate the same serine hydroxyl groups in H1 and H2B histones. Both protein kinases reacted with Ser-38 in H1 histone. With H2B histone as substrate protein kinase A phosphorylated Ser-32 as well as Ser-36, whereas protein kinase G reacted preferentially with Ser-32 and the reaction with Ser-36 was very slow. H3 and H4 histones were practically inactive substrates for protein kinase G. Although H2A histone has not been analyzed, the evidence has raised a possibility that protein kinase G utilizes a portion of the substrate proteins for protein kinase A.
