Log-normal distribution of equiefective doses of norepinephrine and acetylcholine in several tissues. (1972)

Frequency distributions of equieffective doses of norepinephrine in the rat vas deferens, the perfused artery of the rabbit ear, the aortic strip of the rabbit, the nietitating membrane of the spinat cat and the guinea-pig atrium and of acetylcholine in the rat vas deferens are presented. In all six, the distributions on an arthmetic scale tended to deviate from normal but the distributions on a log scale did not. In the three groups of data with the larger N 's, this deviation from normal of the arithmetic frequency distribution was significant by the Kolmogorov-Smirnov test. It is concluded that the distribution of equieffective doses of agonists is generally normal on a log scale but not on an arithmetic scale. Therefore, the means of equieffective doses and the statistical tests of their significance should be based on mean logs or their antilogs, the geometric means, not on arithmetic means.
Noise Control Using Coconut Coir Fiber Sound Absorber with Porous Layer Backing and Perforated Panel (2010)

Problem statement: Noise control was one of the major requirements to improve the living environment. One of the methods to do that is provided by sound absorber. Commonly, multi-layer sound absorbers are applied to absorb broadband noise that was composed of perforated plates, air space and porous material. However, multi-layers sound absorbers effectiveness depends on their construction. This study was conducted to investigate the potential of using coconut coir fiber as sound absorber. The effects of porous layer backing and perforated plate on sound absorption coefficient of sound absorber using coconut coir fiber were studied. Approach: Car boot liners made from woven cotton cloth were used as type of porous layer in the study. This material has been used widely in automotive industry. Perforated plate used was machined with perforation ratio of 0.20, thickness of 1 mm and holed diameter of 2 mm. The samples were tested at the acoustic lab of the Faculty of Engineering and Built Environment, University Kebangsaan Malaysia, according to ASTM E 1050-98 international standards for noise absorption coefficient. Results: The experiment data indicates that porous layer backing can improve noise absorption coefficient at low and high frequencies with significant increasing. 20 mm thick layer coconut coir fiber with porous layer backing exhibit peak value at frequencies between 2750-2825 Hz with maximum value of 0.97. The experimental results also found that the coconut coir fiber with perforated plate gives higher value for lower frequencies range from 600-2400 Hz. The optimum value for coconut coir fiber with perforated panel is around 0.94-0.95 for the frequency range 2600-2700 Hz. Conclusion: Noise absorption coefficient of coconut coir fiber was increased at all frequency when they were backing with Woven Cotton Cloth (WCC). At low frequency, the NAC have significant increasing. This is because WCC have higher flow resistivity than coconut coir fibers, so that sound can be dissipated as it travels through material significantly. The results from the experimental tests show that it has good acoustic properties at low and high frequencies and can used to be an alternative replacement of synthetic based commercial product. By using the porous layer and perforated plate backing to coconut coir fiber, the sound absorber panel shows a good potential to be an environmentally friendly product. This innovative sound absorption panel has a bright future because they are cheaper, lighter and environmentally compare to glass fiber and mineral based synthetic materials.
A Modification to the Complex-Valued MRF Modeling Filter of Interferometric SAR Phase (2014)

This letter focuses on a modified complex-valued Markov random field (CMRF) modeling filter to improve the performance in the filtering of the synthetic aperture radar interferometric phase. In the reference CMRF modeling phase map filter, the CMRF model was employed to update residues and their neighbors. By this, the residues were reduced, and phase jumps were preserved simultaneously. However, residue reduction was still insufficient. Furthermore, incorrect model parameter estimation leads to wrong filtering in some blocks. To solve the two aforementioned problems, we propose a modified CMRF modeling filter, where the original interferogram is divided into overlapped blocks. In addition, the adaptive weighted neighbor values are used to estimate the CMRF model parameters. Both simulated and real data experiments are performed to validate this method.
Modulation by cytokines of leukocyte-endothelial cell interactions. Implications for thrombosis (1990)

Endothelial cells play an important role in the regulation of thrombosis. Normal resting (i.e. unstimulated) endothelial cells exhibit antithrombotic activity. This property is due to an active participation of endothelial cells in the inhibition of platelet adhesion and aggregation, in the inhibition of thrombin generation, in the direct inactivation of thrombin, and in clot lysis through the fibrinolytic system. When endothelial cells are stimulated by cytokines such as tumor necrosis factor (TNF) or interleukin 1 (IL-1), they may switch to an active procoagulant state. On the one hand, thrombin generation can be regulated on the endothelial cell surface by thrombomodulin, which allows the activation by thrombin of protein C which subsequently acquires and expresses potent anticoagulant properties. On the other hand, after activation, the same endothelial cell can express tissue factor on its surface, which will lead to the triggering of the coagulation cascade resulting in the generation of thrombin. TNF has been shown both to induce tissue factor gene expression and to suppress transcription of the thrombomodulin gene in endothelial cells. Many cytokines induce tissue factor gene expression and procoagulant activity in the monocyte/macrophage lineage; they also stimulate adhesion of leukocytes to endothelial cells. Cytokines such as IL-1 or TNF can thus be characterized as important intercellular messengers during the onset of coagulation. The role of these compounds can be schematized as: 1) agents of the stimulation of endothelial cells by leukocytes, 2) agents of stimulation of leukocytes by endothelial cells, 3) localization of the coagulation response through the initiation of endothelial cell-leukocyte interactions. Pharmacological modulation of these responses is possible along two pathways: 1) inhibition of the activation of endothelial cells or leukocytes responsible for cytokine release, 2) inhibition of the cytokine-induced cellular activation responsible for potentiation of procoagulant activity.

Adaptive RTP-compatible audio streaming for handheld clients (ARCASH) (2006)

In developing applications that target more than one platform with varying sizes and capabilities, interoperability is an important issue to consider. To address this, protocols are established and standards are defined. For real-time multimedia streaming, the standard real-time protocol (RTP) could be used. Application development libraries for this protocol are readily available for desktop and for more powerful computing systems. However, despite the advancement of mobile technologies and handheld computing devices, there is still lack of support for the development of mobile applications that utilize this protocol.
Risk factors and prevalence of Demodex mites in young adults (2011)

Demodex mites are ectoparasites often found in follicles of facial skin. Their role in human diseases is under investigation, and a growing number of studies indicated that they contribute to chronic inflammatory conditions of the skin, such as rosacea, blepharitis, otitis externa, alopecia and folliculitis. In our study we tested 96 healthy adults for the presence of Demodex mites. Risk factors influencing presence of mites and skin types of the tested individuals were evaluated. We found Demodex folliculorum or Demodex brevis in 17.7% of the samples, more frequently in males (21.9%) and in older adults (20%). Use of make-up seems to reduce the likelihood of Demodex carriage, while pet ownership, use of shared items and living in close contact with older adults had no significant influence of presence of mites. Demodex positive individuals described their skin to be drier, more prone to erythema, but less for folliculitis compared to Demodex negative subjects.
Cryopreservation of pig embryos. (1997)

The changing global needs for food and animal products require the development of breeding strategies for maximizing genetic improvement while maintaining genetic diversity. Genetic diversity can be conserved by using separate breeding herds; however, they may be expensive to maintain and inbreeding becomes a major concern. Alternative methods are needed to preserve valuable genetic resources in a reasonable and economic manner. Embryo cryopreservation allows indefinite storage in vitro at subambient temperatures where metabolism and other cellular functions are greatly reduced or cease, and upon recovery from storage, normal developmental competence can be resumed. Storage and transportation require little maintenance and there is no expense in animal care and little concern about disease transmission. Although there are methods for routine cryopreservation of germplasm and embryos of most livestock species, development of this technology in the pig industry is far behind and has abated improvements in genetic potential. Pig embryos are very sensitive to hypothermic conditions, and this limits their ability to withstand many conventional methods of preservation. Much research has focused on the high lipid content of pig embryos, and its role in hypothermic sensitivity and cryosurvival. Many studies have reported the conventional freezing of pig embryos, and vitrification has shown promise of eluding the difficulties associated with cooling sensitivity and ice crystallization. Recent research suggests that the embryonic cytoskeleton is susceptible to damage during cryopreservation, and this cellular disruption may be averted by using cytoskeletal stabilizers before preservation. Embryos cryopreserved by conventional freezing and vitrification under the influence of cytoskeletal stabilization have resulted in pregnancies or live offspring from recipient females after surgical transfer. Although cryopreservation technology is less advanced in pigs than in other livestock species, promising research shows evidence that researchers are close to achieving a methodology for preserving pig embryos.

TWO CHROMOSOMAL GENES REQUIRED FOR KILLING EXPRESSION IN KILLER STRAINS OF <i>SACCHAROMYCES CEREVISIAE</i> (1976)

The killer character of yeast is determined by a 1.4 X 10(6) molecular weight double-stranded RNA plasmid and at least 12 chromosomal genes. Wild-type strains of yeast that carry this plasmid (killers) secret a toxin which is lethal only to strains not carrying this plasmid (sensitives).--We have isolated 28 independent recessive chromosomal mutants of a killer strain that have lost the ability to secrete an active toxin but remain resistant to the effects of the toxin and continue to carry the complete cytoplasmic killer genome. These mutants define two complementation groups, kex1 and kex2. Kex1 is located on chromosome VII between ade5 and lys5. Kex2 is located on chromosome XIV, but it does not show meiotic linkage to any gene previously located on this chromosome.--When the killer plasmid of kex1 or kex2 strains is eliminated by curing with heat or cycloheximide, the strains become sensitive to killing. The mutant phenotype reappears among the meiotic segregants in a cross with a normal killer. Thus, the kex phenotype does not require an alteration of the killer plasmid.--Kex1 and kex2 strains each contain near-normal levels of the 1.4 x 10(6) molecular weight double-stranded RNA, whose presence is correlated with the presence of the killer genome.
Formation and removal of B[a]P diol epoxide — DNA adducts in human fibroblasts (1982)

Using xeroderma pigmentosum fibroblasts, deficient in excision repair, as controls to measure the initial rate of (+/-)7 beta,8 alpha-dihydroxy-9 alpha,10 alpha-epoxy-7,8,9,10-tetrahydrobenzo[a]pyrene (B[a]PDE)--DNA adducts removal in normal human fibroblasts, it was found that the maximum amount of carcinogen DNA adducts occurred 1 h after the addition of B[a]PDE, and that during the first hour approximately 12% of the DNA--carcinogen adducts had already been removed. Thus the formation and removal of DNA--carcinogen adducts occurred simultaneously within the first hour after B[a]PDE addition to confluent fibroblasts. Examination of excision repair over an extended period showed that during a further 6 h, DNA adducts were removed at a rate four times slower than that observed during the first hour. Since the maximum level of B[a]PDE--DNA adducts was observed 1 h after the addition of B[a]PDE to the cells in culture, this suggested that the rate of breakdown of B[a]PDE was much slower than that observed in vitro. Further experiments indeed indicated that the rate of hydrolysis of B[a]PDE within the cell was significantly decreased. Thus, the stability of B[a]PDE inside the cell is governed by very different parameters than those observed in vitro.
Effective Transfer of Technology from Research to Development (1977)

A model is developed to illustrate an effective way of transferring technology, particularly one that is new to a corporation, by overlapping a declining research effort with an increasing engineering and manufacturing effort. This transition stage, when a project has visibility but is competing for company resources, allows all groups to become involved while the project develops. Project leadership is critical during this phase of overlap and allows either a single- or multiple-leader approach to be effective. New research talent, which is often added at the start of a product cycle, can follow a planned interaction program that includes long-range planning, technological forecasting, budgeting, and a research survey to develop a research portfolio ready to be transferred to the development phase.

Synthesis of<i>N</i>-aryl-2-amino-4-oxo-3,4-dihydrothieno[2,3-d]pyrimidine-6-carboxamides (2005)

Synthetic routes for the preparation of methyl 2-amino-4-methoxythieno[2,3-d]pyrimidine-6-carboxylate (4) - useful intermediate for lipophilic and classical antifolates from 2-amino-4,6-dichloropyrimidine-5-car-baldehyde (1) have been studied. It has been shown that more efficient synthesis of compound 4 includes the preparation of 4-methoxy derivative 7 and subsequent tandem substitution/annulation reaction with methyl mercaptoethanoate in dimethylformamide in the presence of potassium carbonate and molecular sieves 4 Å. Compound 4 was used for the synthesis of N-aryl 2-amino-4-oxo-3,4-dihydrothieno[2,3-d]-pyrimidine-6-carboxamides 10a-c, including an analog of folic acid with amide bridge - N-(4-{[(2-amino-4-oxo-3,4-dihydrothieno[2,3-d]pyrirnidin-6-yl)carbonyl]amino}-benzoyl)-L-glutamic acid (10c).
Web personalization integrating content semantics and navigational patterns (2004)

The amounts of information residing on web sites make users' navigation a hard task. To address this problem, web sites provide recommendations to the end users, based on similar users' navigational patterns mined from past visits. In this paper we introduce a recommendation method, which integrates usage data recorded in web logs, and the conceptual relationships between web documents. In the proposed framework, the usage-oriented URI representation of web pages and users' behavior is augmented with content-based semantics expressed using domain-ontology terms. Since the number of multilingual web sites is constantly increasing, we also propose an automatic method for uniformly characterizing a web site's documents using a common vocabulary. Both methods are integrated in the semantic web personalization system SEWeP.
Modification of lignin and its application as char agent in intumescent flame‐retardant poly(lactic acid) (2012)

Abstract Urea‐modified lignin was prepared according to the Mannich reaction and well characterized by Fourier transform infrared spectrometer, elemental ananlyses, and scanning electron microscopy (SEM). Ammonium polyphosphate (APP) and urea‐modified lignin were added into poly(lactic acid) (PLA) as a novel intumescent flame‐retardant (IFR) system to improve flame retardancy of PLA. The flammability of IFR–PLA composites was studied using limiting oxygen index, UL‐94 vertical burning method and cone calorimeter test, and their thermal stability was evaluated by thermogravimetric analysis. The results showed that the urea‐modified lignin combined with APP exhibited much better flame retardancy and thermal stability than that of the combination of virgin lignin and APP. The improvement may be attributed to the better char morphology with more phosphoric char evidenced by SEM and X‐ray photoelectron spectroscopy. POLYM. ENG.

Protection against remote code execution exploits of popular applications in Windows (2014)

The objective of Malicious Remote Code Execution Exploits is to remotely execute code transparently to the user, and without relying on user interaction, in order to infect targeted machines. This comparative study examines the effectiveness of different proactive exploit mitigation technologies included in popular endpoint security products and specialized anti-exploit tools. The study focuses on exploits of popular applications running on Windows XP SP3 with Internet Explorer (IE8). As such, the Microsoft Enhanced Mitigation Experience Toolkit (MS-EMET) is used as a reference standard for all exploit mitigation solutions. The study compares the effectiveness of endpoint security products and anti-exploit tools by separating measurements of protections in common with MS-EMET from measures of protections supplemental to MS-EMET. This is done in order to understand not just the relative competitive effectiveness of the individual products and tools but also to understand the overall capabilities of the Windows endpoint security solutions to combat the remote code execution exploit capabilities of the overall Windows malware ecosystem.
On traceability for safety critical systems engineering (2005)

Traceability is the common term for mechanisms to record and navigate relationships between artifacts produced by systems development processes. It is especially vital for critical systems which must satisfy a range of functional and non-functional requirements, including safety, reliability and availability. Regulation normally requires critical systems are certified before entering service. This involves submission of a safety case - a reasoned argument and supporting evidence that such requirements have been met and that the system is acceptably safe. Safety engineers use a range of analysis techniques to gather evidence for a safety case. Most have tool support, although poor integration limits traceability between their respective data sets. This paper proposes a framework that enables links to be established and consistency maintained across data from disjoint safety analysis tools.

Introduction (2013)

Abstract This chapter introduces Olivia Mannging as an English woman who was a member of the English colony, which was composed principally of British embassy staff, businessmen, and journalists. It was a time when the daily news was full of the domino collapse of Europe. Olivia Manning was a wry and witty observer of the political and social scene in Bucharest, and the author of several short stories and one well-received novel, The Wind Changes, published in 1937, whose setting is the Irish ‘Troubles’ and whose theme is the eventual futility of political protest. This chapter also confirms that her novel impressed critics with its seamless integration of historical actuality into fictional narrative.
