Homologous cysteine proteinases of pathogenic and nonpathogenic Entamoeba histolytica. Differences in structure and expression. (1991)

A cDNA clone derived from the gene encoding a cysteine proteinase of pathogenic Entamoeba histolytica was isolated using an antiserum to the purified enzyme. This clone was used to identify the homologous clone in a cDNA library from nonpathogenic E. histolytica. Sequence analysis and comparison of the predicted amino acid sequences revealed a sequence divergence of 16%. Southern blot analyses indicated that (i) pathogenic isolates may contain more genes coding for these or related enzymes than nonpathogenic isolates, (ii) the structure and organization of these genes are conserved within each group of amoebae, and (iii) none of the genes is found in both pathogenic and nonpathogenic E. histolytica, underlining the notion that the two groups are genetically distinct. Northern blot analyses suggested that the cysteine proteinase is expressed by pathogenic isolates in substantially higher amounts than by nonpathogenic isolates. Overexpression of this enzyme may be an important factor in the pathogenicity of E. histolytica.
A QoS adaptive multimedia transport system: design, implementation and experiences (1997)

The long awaited `new environment' of high speed broadband networks and multimedia applications is fast becoming a reality. However, few systems in existence today, whether they be large scale pilots or small scale test-beds in research laboratories, offer a fully integrated and flexible environment where multimedia applications can maximally exploit the quality of service (QoS) capabilities of supporting networks and end-systems. In this paper we describe the implementation of an adaptive transport system that incorporates a QoS oriented API and a range of mechanisms to assist applications in exploiting QoS and adapting to fluctuations in QoS. The system, which is an instantiation of the Lancaster QoS Architecture, is implemented in a multi ATM switch network environment with Linux based PC end systems and continuous media file servers. A performance evaluation of the system configured to support video-on-demand application scenario is presented and discussed. Emphasis is placed on novel features of the system and on their integration into a complete prototype. The most prominent novelty of our design is a `distributed QoS adaptation' scheme which allows applications to delegate to the system responsibility for augmenting and reducing the perceptual quality of video and audio flows when resource availability increases or decreases.
Towards the historical dynamics of a european public sphere? Searching for “Europe” and “European issues” in polish post-war studies on media contents (2011)

This article starts from the premise that rather than being a solely contemporary notion or a concept related to the development of the European Union, European Public Sphere (EPS) should be viewed as a historically conditioned process, which draws on a longue durée of European perceptions and imaginaries constructed and disseminated in the national contexts. By looking at existent analyses of national media contents, this article, which draws on the analysis of over a hundred media studies, provides an extensive and critical examination of post-War Polish media discourses on “Europe” and “European issues” (including definitions of “Europe”, “Europeanness”, “European identity”, and “European values”). Seeing the role that those issues played in Polish media discourses during the period between 1945 and 2005 (i.e. from the end of World War II, through the development and fall of the Communism, up until and including Polish accession to the EU), the article locates when and where ethical notions related to the idea of Europe were negotiated and appropriated within media discourses. The article also attempts to find examples of (possibly) transnational and event-specific aspects of reporting in order to discover the historical development of either Polish or transnational media constructions of a European Public Sphere.
Site-Specific Recombination of Temperate <i>Myxococcus xanthus</i> Phage Mx8: Genetic Elements Required for Integration (1999)

Like most temperate bacteriophages, phage Mx8 integrates into a preferred locus on the genome of its host, Myxococcus xanthus, by a mechanism of site-specific recombination. The Mx8 int-attP genes required for integration map within a 2.2-kilobase-pair (kb) fragment of the phage genome. When this fragment is subcloned into a plasmid vector, it facilitates the site-specific integration of the plasmid into the 3' ends of either of two tandem tRNAAsp genes, trnD1 and trnD2, located within the attB locus of the M. xanthus genome. Although Int-mediated site-specific recombination occurs between attP and either attB1 (within trnD1) or attB2 (within trnD2), the attP x attB1 reaction is highly favored and often is accompanied by a deletion between attB1 and attB2. The int gene is the only Mx8 gene required in trans for attP x attB recombination. The int promoter lies within the 106-bp region immediately upstream of one of two alternate GTG start codons, GTG-5208 (GTG at bp 5208) and GTG-5085, for integrase and likely is repressed in the prophage state. All but the C-terminal 30 amino acid residues of the Int protein are required for its ability to mediate attP x attB recombination efficiently. The attP core lies within the int coding sequence, and the product of integration is a prophage in which the 3' end of int is replaced by host sequences. The prophage intX gene is predicted to encode an integrase with a different C terminus.
Bremsstrahlung from a Plasma (1962)

The effect of correlations on bremsstrahlung from a plasma is studied by using in Kirchhoff's law an absorption coefficient obtained from a Boltzmann-Fokker-Planck equation. A simple derivation of the Fokker-Planck coefficients is given by relating them to familiar dc coefficients. A dispersion formula giving the principal behavior of the absorption coefficient is obtained from a first iterate solution of the Fokker-Planck equation, treating the scattering of electrons by ions as a perturbation. The absorption coefficient reduces to the incoherent radiation result at frequencies much higher than the plasma frequency. At the plasma frequency it is greater than the incoherent absorption coefficient by a factor of O[(nλD3)12], where n is the electron density and λD is the Debye length. The effect of surface reflections on the net emission is discussed.
Transformation of Penicillium chysogenum with selection for increased resistance to benomyl (1989)

Incubation of protoplasts of Penicillium chrysogenum with the plasmid pBT-3 permitted selection of transformants on the basis of increased resistance to the anti-fungal agent benomyl. Transformants were obtained at a frequency of 1-2 per microgram of DNA. Southern analysis revealed that transformation had occurred by integration of vector sequences into the host genome.

Calculation of the thermodynamic properties of aqueous silica and the solubility of quartz and its polymorphs at high pressures and temperatures (1977)

Regression of experimental solubility data with theoretical equations providing for the intrinsic properties of SiO/sub 2/ and the calorimetric consequences of electrostriction collapse and solvation affords close approximation of the thermodynamic behavior of aqueous silica to 5 kb and 600/sup 0/C. The standard molal volume of aqueous silica (V/sup 0/) decreases as a sigmoid function of temperature at constant pressure but increases as pressure increases at constant temperature. In contrast, the standard molal heat capacity (C/sup 0//sub p/) maximizes with increasing pressure at intermediate temperatures. C/sup 0//sub p/, which is negative at low temperatures, exhibits a maximum also as a function of temperature at constant pressure. Owing to the behavior of the partial derivatives of the dielectric constant of H/sub 2/O with respect to pressure and temperature, both V/sup 0/ and C/sup 0//sub p/ approach -infinity at the critical point of H/sub 2/O, but at low temperatures where V/sup 0/ is positive, C/sup 0//sub p/ is negative and decreases dramatically with decreasing temperature at constant pressure. The broad extrema exhibited by curves representing the solubility of ..cap alpha..-quartz as a function of temperature at pressures less than or equal to a kilobar are a consequence of these variations in V/supmore » 0/ and C/sup 0//sub p/. At high temperatures and low pressures, changes in the thermodynamic properties of aqueous silica are controlled primarily by the electrostatic properties of H/sub 2/O, but at low temperatures the local solvent structure dominates the temperature and pressure dependence of V/sup 0/ and C/sup 0//sub p/. The geologic consequences of the thermodynamic behavior of aqueous silica can be predicted by combining the theoretical equations and regression coefficients with thermodynamic data for minerals and other aqueous species, which permits calculation of the distribution of SiO/sub 2/ among silicates and H/sub 2/O-rich hydrothermal solutions at high pressures and temperatures.« less
How Well are Mathematics Common Core Standards Reflected in Mathematics College Readiness Expectations?--RESEARCH (2013)

On February 10, 2010, Kentucky made history by being the first state to adopt the Common Core State Standards (CCSS). The CCSS were designed to be more rigorous, focused, and applicable (Holiday, 2010) than previous standards. The adoption of these standards was predicated by Senate Bill 1, Unbridled Learning. This bill required legislative bodies to develop a unified strategy to reduce the high college remediation rates of recent high school graduates by at least fifty percent before 2014. Along with high schools being required to address underprepared college students, state universities were to align their remediation courses with the new standards. This research study compares content assessed on course finals from Kentucky public universities in highest-level remedial mathematics courses and content assessed on college placement examinations. The study addressed the following two research questions: (1) what mathematical prerequisite knowledge do state universities consider necessary to be college ready? Specifically, 1a) What content domains do the state universities emphasize in their remediation courses?; 1b) Is there consistency across the state public universities with regard to the content domains?; and (2) Is there consistency between Kentucky’s mathematics placement assessments (ACT, COMPASS, and KYOTE) and with four-year universities’ Kentucky Mathematics College Readiness Expectations (KM-CRE)? Findings suggested that consistency across universities and placement examinations in content emphasis exists. Examinations were heavily weighted in Algebra readiness (Expressions and Equations, Functions, and Algebra).
Organotin(IV) Derivatives of N-Tolyl-m-methoxybenzohydroxamic Acid: Synthesis and Structural Elucidation (2009)

A series of organotin (IV) complexes of the type R2SnL2, where R = phenyl, butyl and methyl and HL = NTolyl-m-methoxybenzohydroxamic acid were synthesized and characterized by physico-chemical (elemental analysis,and electrolytic conductance) and spectral Infrared and (1H , 13C and 119Sn NMR) techniques. Monomer structures forthe complexes, bidentate and octahedral geometry was proposed for the complexes prepared.
An Array Antenna for Both Long- and Medium-Range 77 GHz Automotive Radar Applications (2017)

A novel array antenna with a flat-shoulder shaped radiation pattern is proposed as the transmitting antenna for 77 GHz automotive radar application. When it is used in an automotive radar comprising one transmitter and multiple identical receivers, it can meet the demands of both long-range and medium-range detections without switching the operation mode back and forth between the long-range radar scenario and the medium-range radar scenario. The proposed antenna concept is fully introduced to explain its mechanism. An unconventional array was synthesized to achieve the desired flat-shoulder shaped radiation pattern. Prototype of the proposed array antenna was also designed according to the array synthesis result, which consists of several linear series-fed patch arrays and a substrate-integrated waveguide power and phase distributing network. Fabrication and measurement of the prototype array antenna were completed, showing a good agreement between the measured data and the synthesized as well as the simulation results, thereby validating the design.
[Cytochrome p450 genes and their application in plant improvement]. (2003)

Cytochrome P450s are heme-containing mixed-function oxidases,involving in lots of biochemical reactions. They play an important role in preventing plants from pathogen and insect attacks and environmental stress. Sequence analysis of genomes has revealed that P450 is a gene super-family. Many cytochrome P450s have been characterized and cloned. Some of them have been used in plant genetic improvement. A great progress has been made in using these P450 genes to create the transgenic plants with multiple resistances,male sterility, higher capability to dissolve toxic chemicals and pollutants and effective productivity of high valuable compounds,indicating P450 genes have a broad prospect with great potential application.
Selection and Prioritization of Test Cases by Combining White-Box and Black-Box Testing Methods (2013)

In this paper, we present a methodology that combines both white-box and black-box testing, in order to improve testing quality for a given class of embedded systems. The goal of this methodology is generation of test cases for the new functional testing campaign based on the test coverage information from the previous testing campaign, in order to maximize the test coverage. Test coverage information is used for selection of proper test cases in order to improve the quality of testing and save available resources for testing. As an output, a set of test cases is produced. Generated test cases are processed by the test Executor application that decides whether results have passed or failed, based on the results of image grabbing, OCR text extraction, and comparison with expected text. The presented methodology is finally validated by means of a case-study targeting an Android device. The results of the case study are affirmative and they indicate that the proposed methodology is applicable for testing embedded systems of this kind.
The involvement of extracellular proteinases and proteinase inhibitors in mammalian fertilization (1994)

Extracellular proteinases and proteinase inhibitors have been known to play many important roles in various biological systems. They are also important for reproductive functions of the mammals. Kallikrein stimulates human sperm motility. Porcine antithrombin III (AT III) has been identified to be a sperm-motility-stimulating protein and a chemoattractant for boar sperm. AT III-immunoreactive molecules are also detected on the zona pellucida of ovulated porcine eggs and are suggested to act as a sperm receptor. Proteinase inhibitors in the seminal plasma act as decapacitation factors. Both the proteinase inhibitors in the seminal plasma and the trypsin-like protein(s) on the surface of the sperm head play important roles in the sperm-egg interaction. The trypsin-like protein(s) are also involved in the induction of acrosome reaction. Plasminogen activator was demonstrated to be a trigger of the zona reaction. In summary, the roles of extracellular proteinases and proteinase inhibitors in the mammalian fertilization process are diversified and worthy of further investigation.
A Method for Obtaining Skeletons Using a Quasi-Euclidean Distance (1968)

The problem of obtaining the skeleton of a digitized figure is reduced to an optimal policy problem. A hierarchy of methods of defining the skeleton is proposed; in the more complicated ones, the skeleton is relatively invariant under rotation. Two algorithms for computing the skeleton are defined, and the corresponding computer programs are compared. A criterion is proposed for determining the most significant skeleton points.
A simple method of ATM ABR congestion control (2003)

We present a method to avoid congestion of ABR (available bit rate) traffic in ATM (asynchronous transfer mode) networks using the end-to-end delay experienced by resource management (RM) cells. When the forward RM cells leave the source, the source records the departure time and when they return to the source after traversing the network from source to destination and back, the source records the arrival time. The difference of these two is the round trip time (RTT). The RTT is used to control the cell admission rate by the source. In contrast to other work, this method does not need any measurement inside the network. We have studied the performance of the controller via simulations on OPNET.
[The 3-wall plastic repair of the inguinal canal in the surgical treatment of inguinal hernia]. (1993)

The method of plasty of the inguinal canal consisting in strengthening of its inferior wall achieved by means of placement of the sutures embracing the inguinal ligament permitting to prevent the development of its disfibration dissection and rupture of the fibers is suggested. One hundred and forty-one operation was performed. The long-term results were studied at the period of from 2 to 10 years. Disease recurrence was noted in 1 (0.7%) patient.
Human marrow cells capable of erythropoietic differentiation in vitro: definition of three erythroid colony responses (1977)

A systematic study has been undertaken to analyze the spectrum of erythropoietic colonies obtained in cultures of human marrow cells plated in methyl cellulose. Colonies were identified as erythropoietic on the basis of the appearance in them of hemoglobin-containing erythroblasts. As found previously in mouse marrow cultures, three sequentially appearing types of colonies which differed in their ultimate cluster content could be readily distinguished. Small erythroid colonies containing 1-2 clusters reached a peak after 7-8 days; small bursts containing 3-8 clusters reached a peak after 10-12 days; and large bursts containing greater than 16 clusters reached a peak after 17-20 days. The previously reported enhancing effect of human leukocyte conditioned medium on burst formation seen in cultures of human nonadherent cells was found to be due largely to an effect on the formation of the largest, late appearing type of burst. By analogy with the mouse, the progenitors of such bursts would represent a primitive cell type which has a close relationship with pluripotent stem cells, as well as a second and independent close relationship to the progenitors of granulopoietic colonies.
Rapid <i>In Vitro</i> Propagation of Bioenergy Crop Miscanthus Sacchariflorus (2012)

Miscanthus sacchariflorus is an important perennial bioenergy feedstock, but no information is available regarding plant rapid propagation from in vitro seed grown plantlets. The present study investigates the effects of the types and combination of plant growth regulators on tissue culture system of M. sacchariflorus. Shoot apices from in vitro germinated seedling explants were tested for adventitious shoot proliferation. The highest level of proliferation (proliferation coefficient 11.66) was obtained when shoot apices were cultured on Murashige and Skoog (MS) medium supplemented with 0.5 mg L−1 6-benzyladenine (BA), 0.05 mg L−1 α–naphthalene acetic acid (NAA), 3% sucrose, and 0.8% agar. The highest root number (13.33) and root length (9.67 cm) were obtained when adventitious shoots were cultured on half-strength MS medium supplemented with 0.4 mg L−1 NAA, 3% sucrose, and 0.8% agar. The efficient plant regeneration system developed here will be helpful for rapid propagation and further genetic improvement in M. sacchariflorus.
Impact of Sampling Parameters on the Radical Scavenging Potential of Olive (Olea europaea L.) Leaves (2009)

The impact of sampling parameters, that is, cultivar, leaf age, and sampling date, on the radical scavenging potential of olive leaf extracts was examined via the DPPH(*) and other assays. Total phenol content was estimated colorimetrically and by fluorometry, whereas phenol composition was assessed by RP-HPLC coupled with diode array, fluorometric, and MS detection systems. Oleuropein was not always the major leaf constituent. Considerable differences noted in individual phenol levels (hydroxytyrosol, oleuropein and other secoiridoids, verbascoside, and flavonoids) among samples were not reflected either in the total phenol content or in the radical scavenging potential of the extracts. It can be suggested that olive leaf is a robust source of radical scavengers throughout the year and that differentiation in the levels of individual components depends rather on sampling period than on cultivar or age. The latter does not present predictable regularity. Exploitation of all types of leaves expected in an olive tree shoot for the extraction of bioactive compounds is feasible.
Flexible electrode for long-life rechargeable sodium-ion batteries: effect of oxygen vacancy in MoO<sub>3−x</sub> (2016)

A long-life sodium ion cathode based on MoO<sub>3−x</sub> exhibits near theoretical capacity, excellent rate capability, and much enhanced cycling stability through careful control of the oxygen vacancy in MoO<sub>3−x</sub>.
DCT coefficient-based error detection technique for compressed video stream (2002)

In the process of transmission of digital encoded video bit streams over a physical network, the data is corrupted by random bit errors, which has a severe effect on the decoded video quality. The success of an error concealment algorithm depends heavily on the detection of the corrupted regions. We propose a new error detection algorithm for discrete cosine transform based video coding. Our algorithm detects thus far undetectable erroneous regions with a very little increase in computational complexity. We show that erroneous blocks in the decoded frames can be detected by monitoring the variation of average energy from block to block. To avoid false detection due to the presence of strong edges we employ a very fast DCT coefficient based edge detection algorithm. Computer simulation shows that the quality of the recovered image is significantly improved in comparison to well-known methods.
