NMR spectroscopic investigations with ethyl 1‐(hetero)aryl‐5‐hydroxy‐1<i>H</i>‐pyrazole‐4‐carboxylates (1995)

Abstract The synthesis of a series of ethyl N ‐1‐(hetero)aryl‐5‐hydroxy‐1 H ‐pyrazole‐4‐carboxylates by reaction of diethyl ethoxymethylenemalonate with the appropriate hydrazines is described. According to nmr‐spectro‐scopic investigations ( 1 H‐ and 13 C‐nmr) the title compounds exist as 5‐hydroxy tautomers in deuteriochlo‐roform as well as in deuteriodimethyl sulfoxide solution.
Virologic and serologic studies of zoo birds for Marek's disease virus infection (1975)

One hundred and eleven zoo birds representing 49 species in 14 orders were examined for Marek's disease (MD) herpesvirus (MDHV) infection. MDHV was isolated from 10 birds, all belonging to genus Gallus. The precipitating antibodies against MDHV were demonstrated only in the Gallus birds, when 51 selected birds including 34 Galliformes and 17 other birds representing 12 species from nine orders were examined. The 10 MDHV isolates all induced morphologically similar plaques in cell cultures closely resembling those of HN strain, a low pathogenic isolate of MDHV. Six of the 10 isolates, when inoculated into an experimental line of chickens highly susceptible to MD, caused only a minimal degree of histologic lesions without causing clinical MD, gross MD lesions, or deaths from MD. Natural hosts of MD are probably Galliformes, primarily affecting Gallus and less often other genera of Galliformes.
Het inrichten van een SOA governance levenscyclus (2008)

De verspreiding van diensten in een Service-Oriented Architecture (SOA) maakt het moeilijk om deze omgeving in controle te houden. Diensten worden op verschillende plekken in de organisatie beheerd, waardoor de samenhang verloren kan gaan. Het concept van SOA governance is ontstaan om een oplossing te bieden voor het sturingsprobleem in SOA’s. In dit artikel wordt een levenscyclus benadering gebruikt om een praktische aanpak voor SOA governance op te stellen. Deze aanpak bestaat uit het definiëren van strategische SOA doelen, het klaarmaken van de organisatie, het beheer van de dienstenportefeuille, beheer van de levenscyclus van diensten, toepassing van reguleringen en het beheer van service niveau’s. Door het gebruik van een volwassenheidsmodel is het mogelijk om efficiente sturing toe te passen zonder te verzanden in bureaucratische procedures. Op basis van interviews kan geconcludeerd worden dat de meeste SOA projecten – zelfs in hun beperkte omvang – problemen geven op sturingsgebied.

The mutation identified in exon 5 of the IkappaBalpha gene in Hodgkin lymphoma may play a role in the pathogenesis of Hodgkin lymphoma.
Influenzal Meningitis The Relation of Age Incidence to the Bactericidal Power of Blood Against the Causal Organism (1933)

Summary 1.Influenzal meningitis is rarely seen under two months of age or beyond six years of age. About 80 per cent of the cases occur between the ages of two months and three years. 2.The bactericidal power of whole defibrinated blood in various age groups for a meningitic strain of B. influenzae has been studied. 3.Cord blood and the blood of infants under two months of age has considerable bactericidal power. 4.With rare exceptions the blood of children between the ages of two months and three years has practically no bactericidal power. 5.After three years the bactericidal power gradually rises and appears to be permanent in adult life.
A new standard for sulphur collection systems with integrated degassing(RSC-D)~(TM) (2010)

Degassing to w(H_2S) less than 0.001%is generally recommended for safety and improved grinding and forming operations.The six most prominent commercial degassing technologies capable of meeting the specification are described.All degassing technologies employ a combination of agitation and gas stripping and some also utilize a liquid or solid-bed catalyst,and/or cooling.The emphasis is put on WorleyParsons' new Rameshni Sulphur Collection-Degassing(RSC-D)~(TM) system.The system uses a liquid jet pump or eductor for colloting sulphur instead of gravity,allowing to maintain everything above grade and a more distant sulphur pit from the sulphur plant.The new invention eliminates the gravity flow constrains and plugging problems while improving the reliability and operability of sulphur collection.
Sign language interpreter using a smart glove (2014)

Sign language is the communication medium for the deaf and the mute people. It uses hand gestures along with the facial expressions and the body language to convey the intended message. This paper proposes a novel approach of interpreting the sign language using the portable smart glove. LED-LDR pair on each finger senses the signing gesture and couples the analog voltage to the microcontroller. The microcontroller MSP430G2553 converts these analog voltage values to digital samples and the ASCII code of the letter gestured is wirelessly transmitted using the ZigBee. Upon reception, the letter corresponding to the received ASCII code is displayed on the computer and the corresponding audio is played.
Polish language modelling for speech recognition application (2017)

The article presents statistical word-based and phoneme-based language models for automatic speech recognition application in Polish. Appropriate orthographic and phonemic language corpora allow to perform statistical analysis of the language and to develop statistical word-based and phoneme-based language models. Development of statistical language models helps to predict a sequence of recognized words and phonemes. Developed statistical language models have been compared and the best of them has been proposed as the best suited for automatic speech recognition application for Polish. Word-based and phoneme-based language models can be used to develop hybrid language models and effectively contribute to improve speech recognition effectiveness based on statistical methods. The achieved research results and conclusions can also be applied to speech recognition application for other languages.
Pennsaid therapy for osteoarthritis of the knee: a systematic review and metaanalysis of randomized controlled trials. (2006)

Pennsaid is an effective topical NSAID in patients with OA of the knee. Apart from minor localized skin reactions, Pennsaid was as safe as VCP. It is not known whether the favorable results of Pennsaid can be extrapolated to other topical NSAID preparations. Pennsaid deserves further consideration when the existing treatment guidelines for OA of the knee are updated.
Inverter Nonlinear Error Compensation Using Feedback Gains and Self-Tuning Estimated Current Error in Adaptive Full-Order Observer (2015)

The performance of a speed-sensorless induction motor drive is poor at low-speed range. This is because the inverter nonlinear error, such as inaccurate motor parameters, deadtime, turn on/off delay, and on-state voltage drop of power switches, has strong influence on the speed estimation at low-speed range. In this paper, the feedback gains of an adaptive full-order observer are designed to guarantee the stability of speed estimation and to reduce the influence of the inverter nonlinear error on the speed estimation. In addition, the estimated current error caused by the inverter nonlinear error is identified offline. It is stored in the lookup table to compensate for the influence of the inverter nonlinear error on the speed estimation. The feasibility of the proposed method is verified by experiments.

About Our Cover (1971)

Abstract The seedless triploid hybrid watermelon is still relatively new to Horticulture. The seedless watermelon became a potential reality when it was learned that colchicine could be used to convert diploid strains into reproducible tetraploids for purposes of production (2). For the early beginning we must go back to 1889 (3), when B. Pernice of Palermo, Sicily, published unmistakable evidence that colchicine causes metaphasic-arrest among actively mitotic cells (10).

Disease Backs Cancer Origin Theory (2004)

Almost all cancer cells have gained or lost entire chromosomes. Despite the genetic turmoil this causes, scientists have disagreed for nearly a century about whether this abnormality and other types of genomic instability, such as that caused by DNA repair defects, are the starting gun for cancer or merely a result of it. A study published online in Nature Genetics this week provides the strongest evidence yet for the starting gun theory by showing that mutations in a gene involved in ensuring proper chromosome number result in childhood cancer.
Control of yellow stem borer,<i>Scirpophaga incertulas</i>(Lepidoptera: Pyralidae) by mating disruption on rice in India: effect of unnatural pheromone blends and application time on efficacy (1996)

Abstract Single applications of slow-release pheromone formulations were used to control yellow stem borer, Scirpophaga incertulas Walker, by mating disruption in two trials on rice in India. The first trial compared the efficacy of two formulations containing 1:10:1 and 1:10:0 ratios of (Z)-9-hexadecenal, (Z)-ll-hexadecenal and (Z)-9-octadecenal, components of the S. incertulas pheromone, and a commercially-available formulation, Selibate CS, containing the related Chilo suppressalis Walker pheromone, a 1:10:1 blend of (Z)-9-hexadecenal, (Z)-ll-hexadecenal and (Z)-13-octadecenal, with farmers' practice plots treated with insecticides. Pheromone trap catches indicated that in each of the pheromone-treated plots the catches of male moths were reduced by up to 98% compared with catches in the insecticide-treated plots suggesting that pheromone-mediated communication was disrupted. Larval damage ranged from 5.7 to 8.1% white heads (WH) in the insecticide-treated plots compared to a significantly reduced range of 2.1 to 2.4% WH in the pheromone-treated plots. There was no significant difference between the damage estimates recorded for each of the different pheromone treatments. A second trial compared the effect on efficacy of applying the two-component pheromone formulation on different dates, 9–12 and 39–44 days after transplanting. Both pheromone treatments gave significantly lower levels of WH damage compared to equivalent insecticide treated plots; 1.8, 2.0, and 6% respectively. In both trials rice grain yields increased by between 5 and 12% in pheromone-treated plots compared to insecticide treated plots, which was due, at least in part, to the cumulative effect of reduced stem borer damage in both the tillering and reproductive stages of the crop cycle. The formulations exhibited pseudo-zero order release rates with field lives of between 70 and 90 days.
The Salutary Effects of DHA Dietary Supplementation on Cognition, Neuroplasticity, and Membrane Homeostasis after Brain Trauma (2011)

The pathology of traumatic brain injury (TBI) is characterized by the decreased capacity of neurons to metabolize energy and sustain synaptic function, likely resulting in cognitive and emotional disorders. Based on the broad nature of the pathology, we have assessed the potential of the omega-3 fatty acid docosahexaenoic acid (DHA) to counteract the effects of concussive injury on important aspects of neuronal function and cognition. Fluid percussion injury (FPI) or sham injury was performed, and rats were then maintained on a diet high in DHA (1.2% DHA) for 12 days. We found that DHA supplementation, which elevates brain DHA content, normalized levels of brain-derived neurotrophic factor (BDNF), synapsin I (Syn-1), cAMP-responsive element-binding protein (CREB), and calcium/calmodulin-dependent kinase II (CaMKII), and improved learning ability in FPI rats. It is known that BDNF facilitates synaptic transmission and learning ability by modulating Syn-I, CREB, and CaMKII signaling. The DHA diet also counteracted the FPI-reduced manganese superoxide dismutase (SOD) and Sir2 (a NAD+-dependent deacetylase). Given the involvement of SOD and Sir2 in promoting metabolic homeostasis, DHA may help the injured brain by providing resistance to oxidative stress. Furthermore, DHA normalized levels of calcium-independent phospholipase A2 (iPLA2) and syntaxin-3, which may help preserve membrane homeostasis and function after FPI. The overall results emphasize the potential of dietary DHA to counteract broad and fundamental aspects of TBI pathology that may translate into preserved cognitive capacity.
Molecular Analysis of Carbon Monoxide-Oxidizing Bacteria Associated with Recent Hawaiian Volcanic Deposits (2004)

Genomic DNA extracts from four sites at Kilauea Volcano were used as templates for PCR amplification of the large subunit (coxL) of aerobic carbon monoxide dehydrogenase. The sites included a 42-year-old tephra deposit, a 108-year-old lava flow, a 212-year-old partially vegetated ash-and-tephra deposit, and an approximately 300-year-old forest. PCR primers amplified coxL sequences from the OMP clade of CO oxidizers, which includes isolates such as Oligotropha carboxidovorans, Mycobacterium tuberculosis, and Pseudomonas thermocarboxydovorans. PCR products were used to create clone libraries that provide the first insights into the diversity and phylogenetic affiliations of CO oxidizers in situ. On the basis of phylogenetic and statistical analyses, clone libraries for each site were distinct. Although some clone sequences were similar to coxL sequences from known organisms, many sequences appeared to represent phylogenetic lineages not previously known to harbor CO oxidizers. On the basis of average nucleotide diversity and average pairwise difference, a forested site supported the most diverse CO-oxidizing populations, while an 1894 lava flow supported the least diverse populations. Neither parameter correlated with previous estimates of atmospheric CO uptake rates, but both parameters correlated positively with estimates of microbial biomass and respiration. Collectively, the results indicate that the CO oxidizer functional group associated with recent volcanic deposits of the remote Hawaiian Islands contains substantial and previously unsuspected diversity.

Palladium-Catalysed Heck Reactionsof Alk-1-en-3-ones with Aryl Bromides: A Very Simple Access to (<i>E</i>)-1-Arylalk-1-en-3-ones (2009)

When appropriate reaction conditions are used, very high yields of (E)-1-arylalk-1-en-3-one derivatives can be obtained by palladium-catalysed reactions of alk-1-en-3-ones with aryl bromides. The tetraphosphine cis,cis,cis-1,2,3,4-tetrakis(diphenylphosphinomethyl)cyclopentane in combination with [Pd(C3H5)Cl]2 was found to be a very efficient catalyst for this reaction. In general, higher reaction rates were observed with electron-poor aryl bromides, but the electron-rich aryl bromides 1-bromo-4-(dimethylamino)benzene and 4-bromoanisole also led to the arylated enones in high yields. Even with sterically very congested aryl bromides such as 9-bromoanthracene, 1-bromo-2,4,6-trimethylbenzene or 1-bromo-2,4,6-triisopropylbenzene, the expected (E)-1-arylalk-1-en-3-ones were obtained in moderate to good yields. These enones appear to be unstable under the reaction conditions, and the addition of a small amount of hydroquinone to the reaction mixture was found to be crucial, especially for the vinylation of electron-deficient aryl bromides. A variety of alk-1-en-3-ones has been employed, and better results in terms of substrate/catalyst ratios were obtained when oct-1-en-3-one or hex-1-en-3-one was used than when but-1-en-3-one or pent-1-en-3-one was used. It should be noted that several reactions can be performed with as little as 0.1-0.001 mol% catalyst.
Revealing Trends Based on Defined Queries in Biological Publications Using Cosine Similarity (2012)

Extracting valuable information in terms of number and content of published papers in any field of research will simplify decision making for future researches and investments. A novel and simple text mining approach, called TrendFinder, has been developed in this paper to reveal the content-based trends of expert-defined queries in selected biological published papers during the last five decades. So, in order to evaluate the results, three different data sets were collected and four vectors of selected keywords were considered as the four queries. "Title", "Published date" and the "Abstract" were downloaded for three series of journals namely, "Conservation Biology", "Ecology", and "The American Naturalist" as data sets, including total number of 19,010 papers. In order to show the trend between each query and the Abstract of each paper, Cosine similarity method was used by TrendFinder. Afterwards, three diagrams were demonstrated content-based trends of the four defined queries on the three provided data sets.

GENETIC ANALYSIS OF THE MITOTIC SPINDLE (1996)

Much of our understanding of the molecular basis of mitotic spindle function has been achieved within the past decade. Studies utilizing genetically tractable organisms have made important contributions to this field and these studies form the basis of this review. We focus upon three areas of spindle research: spindle poles, centromeres, and spindle motors. The structure and duplication mechanisms of spindle poles are considered as well as their roles in organizing spindle microtubules. Centromeres vary considerably in their size and complexity. We describe recent progress in our understanding of the relatively simple centromeres of the yeast Saccharomyces cerevisiae and the complex centromeres that are more typical of eukaryotic cells. Microtubule-based motor proteins that generate the characteristic spindle movements have been identified in recent years and can be grouped into families defined by conserved primary sequence and mitotic function.

MR Imaging and Osteoporosis: Fractal Lacunarity Analysis of Trabecular Bone (2006)

We develop a method of magnetic resonance (MR) image analysis able to provide parameter(s) sensitive to bone microarchitecture changes in aging, and to osteoporosis onset and progression. The method has been built taking into account fractal properties of many anatomic and physiologic structures. Fractal lacunarity analysis has been used to determine relevant parameter(s) to differentiate among three types of trabecular bone structure (healthy young, healthy perimenopausal, and osteoporotic patients) from lumbar vertebra MR images. In particular, we propose to approximate the lacunarity function by a hyperbola model function that depends on three coefficients, alpha, beta, and gamma, and to compute these coefficients as the solution of a least squares problem. This triplet of coefficients provides a model function that better represents the variation of mass density of pixels in the image considered. Clinical application of this preliminary version of our method suggests that one of the three coefficients, beta, may represent a standard for the evaluation of trabecular bone architecture and a potentially useful parametric index for the early diagnosis of osteoporosis.

[Studies of sound condition in the reconstructed middle ear with a hydrophone. Initial results]. (1994)

The acoustic result following reconstruction of the middle ear is often disappointing and unpredictable. Apart from biologic factors, this is due to insufficient knowledge of the mechanism of sound transmission through the operated middle ear. Therefore, temporal bone experiments with simulated middle ear operations were set up to investigate the sound transmission following different prosthesis' designs, materials, etc. We developed a tiny hydrophone which has a frequency range from 100 Hz to 10 kHz in order to measure the sound pressure in the cochlear fluid. By comparing the sound pressure in the inner ear with the sound pressure at the drum membrane, we were able to analyze the transfer function of the manipulated middle ear. First results with different reconstruction techniques, prosthesis' designs and attachments demonstrated the usefulness of this measuring technique for the development of acoustically better middle ear reconstructions.
