Thermal analysis of multilevel grid side converters for 10 MW wind turbines under Low Voltage Ride Through (2011)

As the power level of a single wind turbine is continuously pushed up even to 7 MW, the wind power generation system are required to be more reliable, and able to withstand extreme grid disturbances. Moreover, it is becoming a need that the wind power generation system should be more active, and able to contribute to the grid recovery by injecting reactive current during grid faults. Consequently, the full-scale power converter solutions are becoming more and more popular to fulfill the growing challenges in the wind power application. Nevertheless, the loading of the power devices in full-scale power converters, especially during grid faults may compromise the reliability performance and further increase the cost of the system. In this paper, three promising grid side multilevel converter topologies for the next generation 10 MW wind turbines are proposed and basically designed as case study. The operation status, as well as loss and thermal distributions of power devices are investigated, simulated and compared aimed at various Low Voltage Ride Through (LVRT) conditions. It is found that the all of the proposed converter topologies will suffer from higher junction temperature in some heavy loaded power devices especially the diodes under LVRT, and both of the three-level and five-level H-bridge topologies show more potential to reduce the device stress than the well-known three-level Neutral Point Clamped topology.
중학생들의 목표인식과 수학학업성취도 관계에 대한 수학수업요인의 종단매개효과 (2019)

This study examines the longitudinal effect of goal perception, mathematics class factors(perceptions about mathematics teachers (PMT), mathematics classroom attitude), and mathematics academic achievement. This study consists of three research models. First, we examined the longitudinal change of goal perception, perceptions about mathematics teachers (PMT), mathematics classroom attitude, and mathematics academic achievement using latent growth curve modeling. Secondly, the slope of PMT is a critical mediator between the slope of goal perception and the slope of mathematics academic achievement. Finally, the slope of mathematics classroom attitude is a critical mediator between the slope of goal perception and the slope of mathematics academic achievement.
Data were extracted from Seoul Education Longitudinal Study from 2010 to 2012 (in three waves), and the analysis used by middle school students, measured by 4163 students of the three-wave surveys. Latent growth modeling was applied to verify the research problems. The results of the research are as follows. First, the slope of goal perception had positive and significant effects on the slope of PMT and mathematics classroom attitude, respectively. Second, the slope of PMT and mathematics classroom attitude had positively significant effects on the slope of mathematics academic achievement. Finally, it was confirmed that the slopes of PMT and mathematics classroom attitude are critical mediators between the slope of goal perception and the slope of mathematics academic achievement.

Marketing costs, margins and price spread of wheat in Banaskantha district of Gujarat state (2014)

The present study aimed to examine and compute the marketing costs, margins and price spread of wheat and to analyse the movement of wheat prices and arrivals. It is based on data collected from 108 farmers selected from six randomly selected villages and 60 market functionaries in two market areas of Banaskantha district of Gujarat State. The percentage of marketable and marketed surplus increased with increase in size of holdings. The small farmers sold their produce more than marketable surplus either due to distress sale or due to failure of farmers in prediction on-farm requirement. Most of the farmers sold their produce in peak period i.e., April to July. They did not hold stock to lean period because lack of storage facilities and poor financial position of the farmers. Among all the channels, channel-I (Producer-Wholesaler-Retailer-Consumer) was found more efficient to the farmers, because of 94.79 per cent of the produce sold to this channel. Net price received by the grower was Rs.1115 per quintal, which accounted for 73.36 per cent producer's share in consumer's rupees.

Integration Site Selection by Retroviral Vectors: Molecular Mechanism and Clinical Consequences (2008)

Retroviral DNA integration into the host cell genome is an essential feature of the retroviral life cycle. The ability to integrate their DNA into the DNA of infected cells also makes retroviruses attractive vectors for delivery of therapeutic genes into the genome of cells carrying adverse mutations in their cellular DNA. Sequencing of the entire human genome has enabled identification of integration site preferences of both replication-competent retroviruses and retroviral vectors. These results, together with the unfortunate outcome of a gene therapy trial, in which integration of a retroviral vector in the vicinity of a protooncogene was associated with the development of leukemia, have stimulated efforts to elucidate the molecular mechanism underlying integration site selection by retroviral vectors, as well as the development of methods to direct integration to specific DNA sequences and chromosomal regions. This review outlines our current knowledge of the mechanism of integration site selection by retroviruses in vitro, in cultured cells, and in vivo; the outcome of several of the more recent gene therapy trials, which employed these vectors; and the efforts of several laboratories to develop vectors that integrate at predetermined sites in the human genome.
Electronic tuneability of a structurally rigid surface intermetallic and Kondo lattice:CePt5/Pt(111) (2015)

We present an extensive study of the structure, composition, electronic, and magnetic properties of Ce-Pt surface intermetallic phases on Pt(111) as a function of their thickness. The sequence of structural phases appearing in low-energy electron diffraction may invariably be attributed to a single underlying intermetallic atomic lattice. Findings from both microscopic and spectroscopic methods prove compatible with ${\mathrm{CePt}}_{5}$ formation when their characteristic probing depth is adequately taken into account. The intermetallic film thickness serves as an effective tuning parameter which brings about characteristic variations of the cerium valence and related properties. Soft x-ray absorption (XAS) and magnetic circular dichroism (XMCD) prove well suited to trace the changing Ce valence and to assess relevant aspects of Kondo physics in the ${\mathrm{CePt}}_{5}$ surface intermetallic. We find characteristic Kondo scales of the order of ${10}^{2}$ K and evidence for considerable magnetic Kondo screening of the local Ce $4f$ moments. ${\mathrm{CePt}}_{5}/\mathrm{Pt}(111)$ and related systems therefore appear to be promising candidates for further studies of low-dimensional Kondo lattices at surfaces.

Effects of .BETA.-free layer of sub strate on properties of cemented carbide coated with titanium carbide by CVD process. (1985)

The transverse-rupture strength and cutting performance of TiC coated cemented carbide were investigated as a function of thickness of β-free layer of substrate. The WC-β (N)-Co alloy (β(N) = (W, Ti, Ta) (C, N)) was used as the substrate.The transverse-rupture strength of the coated alloy increased with increasing thickness of β-free layer, and it attained a constant value when the thickness was over about 15μm. On the other hand, the results of interrupted turning tests showed that the resistance to impact-failure was improved with increasing thickness. Discussions on the difference in the dependencies of the strength and cutting performance on the thickness of β-free layer were given.
Graphene-Oxide-Coated CuO Nanoparticles for Functionalization of Acetylsalicylic Acid and Diclofenac (2020)

A single-step ultrasonic method (20 kHz, 18 W/cm2) is demonstrated for the functionalization of pristine nonsteroidal anti-inflammatory drugs: acetylsalicylic acid and diclofenac with preformed graphene-oxide-coated CuO nanoparticles. These nanoparticles are positively charged and have a flower-like morphology with a mean size of <340 nm consisting of a pure CuO phase. Ultrasound causes complexation of each drug with these nanoparticles, and as a consequence, new advanced pharmaceutical nanocomposites, acetylsalicylic-acid–graphene-oxide-coated CuO and diclofenac–graphene-oxide-coated CuO, are formed. The surface composition and electronic molecular structure of these nanocomposites are modified at pH values from 1 to 8 through the specific interactions involving Cu–O, C–H, and H-bond formation with the carboxylic and carbonyl groups of acetylsalicylic acid, diclofenac, and graphene oxide.
Antivimentin Autoantibodies in Angioimmunoblastic Lymphadenopathy (1984)

We evaluated the prevalence and specificity of smooth-muscle autoantibodies in 20 serum samples obtained from patients with angioimmunoblastic lymphadenopathy. Smooth-muscle antibodies in high titers were detected in 75 per cent of the samples. No such antibodies were found in 30 normal control serum samples or in 10 samples from patients with non-Hodgkin's lymphoma and 1 of 12 from patients with other types of polyclonal hypergammaglobulinemia were positive. The antibodies were polyclonal and belonged to the IgM, IgG, and IgA classes. They reacted with vimentin, the major polypeptide of the intermediate-filament cytoskeleton of mesenchymal cells. The pattern of tissue reactivity and absorption experiments both show that these antibodies recognize special antigenic determinants of the vimentin polypeptide that are shared by vimentin and other classes of intermediate-filament proteins - namely, keratin and desmin. The frequency of this unusual autoantibody activity in angioimmunoblastic lymphadenopathy suggests that, like hypergammaglobulinemia and a positive Coombs' test, it may represent a useful serologic marker for the disease.
Conserved polynucleotide sequences among the genomes of papillomaviruses (1979)

The DNAs of different members of the Papillomavirus genus of papovaviruses were analyzed for nucleotide sequence homology. Under standard hybridization conditions (Tm - 28 degrees C), no homology was detectable among the genomes of human papillomavirus type 1 (HPV-1), bovine papillomavirus type 2 (BPV-2), or cottontail rabbit (Shope) papillomavirus (CRPV). However, under less stringent conditions (i.e., Tm - 43 degrees C), stable hybrids were formed between radiolabeled DNAs of CRPV, BPV-1, or BPV-2 and the HindIII-HpaI A, B, and C fragments of HPV-1. Under these same conditions, radiolabeled CRPV and HPV-1 DNAs formed stable hybrids with HincII B and C fragments of BPV-2 DNA. These results indicate that there are regions of homology with as much as 70% base match among all these papillomavirus genomes. Furthermore, unlabeled HPV-1 DNA competitively inhibited the specific hybridization of radiolabeled CRPV DNA to bpv-2 DNA fragments, indicating that the homologous DNA segments are common among these remotely related papillomavirus genomes. These conserved sequences are specific for the Papillomavirus genus of papovaviruses as evidenced by the lack of hybridization between HPV-1 DNA and either simian virus 40 or human papovavirus BK DNA under identical conditions. These results indicate a close evolutionary relationship among the papillomaviruses and further establish the papillomaviruses and polyoma viruses as distinct genera.
Comparison of tailored and empiric scan delays for CT angiography of the abdomen. (1996)

Tailoring the scan delay for CT angiography of the abdomen in patients considered to have normal cardiac function requires additional IV contrast agent, time, and patient imaging and does not improve the extent or uniformity of aortic enhancement over that obtained with a standard, empiric scan delay.
Comparison of compensation strategies of structural effects (2012)

High dynamics of machine tool centers lead to high acceleration forces, which deform the machine structure and result in force coupling effects. In order to achieve high productivity combined with high path accuracy at existing machine tools, a numerical compensation of these dynamic effects is desirable. A model of an existing machine tool system allowed the evaluation of various compensation algorithms. The expected deviations of the uncompensated system can be gathered by simulation or measurement and further be used as set trajectory for the NC (offline compensation). Since this compensation values are subjected to the influence of the set point generation and the machine structure, only a marginal reduction of the deviations can be observed. Better results can be achieved by real time calculation of the compensation values based on actual velocity and jerk values (online compensation). Online compensation opens a broad range of possibilities for access points and compensation models. Good results on a model based evaluation of compensation strategies have been reached with compensation superposed directly on the torque feed forward input of the drives evaluated from set acceleration and jerk
GuaA and GuaB Are Essential forBorrelia burgdorferiSurvival in the Tick-Mouse Infection Cycle (2009)

Pathogens lacking the enzymatic pathways for de novo purine biosynthesis are required to salvage purines and pyrimidines from the host environment for synthesis of DNA and RNA. Two key enzymes in purine salvage pathways are IMP dehydrogenase (GuaB) and GMP synthase (GuaA), encoded by the guaB and guaA genes, respectively. While these genes are typically found on the chromosome in most bacterial pathogens, the guaAB operon of Borrelia burgdorferi is present on plasmid cp26, which also harbors a number of genes critical for B. burgdorferi viability. Using molecular genetics and an experimental model of the tick-mouse infection cycle, we demonstrate that the enzymatic activities encoded by the guaAB operon are essential for B. burgdorferi mouse infectivity and provide a growth advantage to spirochetes in the tick. These data indicate that the GuaA and GuaB proteins are critical for the survival of B. burgdorferi in the infection cycle and highlight a potential difference in the requirements for purine salvage in the disparate mammalian and tick environments.
Programmable motion and patterning of molecules on solid surfaces (2004)

Adsorbed on a solid surface, a molecule can migrate and carry an electric dipole moment. A nonuniform electric field can direct the motion of the molecule. A collection of the same molecules may aggregate into a monolayer island on the solid surface. Place such molecules on a dielectric substrate surface, beneath which an array of electrodes is buried. By varying the voltages of the electrodes individually, it is possible to program molecular patterning, direct an island to move in a desired trajectory, or merge several islands into a larger one. The dexterity may lead to new technologies, such as reconfigurable molecular patterning and programmable molecular cars. This paper develops a phase field model to simulate the molecular motion and patterning under the combined actions of dipole moments, intermolecular forces, entropy, and electrodes.
Expected total thyroxine (TT4) concentrations and outlier values in 531,765 cats in the United States (2014–2015) (2019)

TT4 concentrations >3.5ug/dL represent outliers from the expected distribution of TT4 concentration. Furthermore, age has a strong influence on the proportion of cats. These findings suggest that patients with TT4 concentrations >3.5ug/dL should be more closely evaluated for hyperthyroidism, particularly between the ages of 7 and 14 years. This finding may aid clinicians in earlier identification of hyperthyroidism in at-risk patients.
Possible participation of polymorphonuclear cells stimulated by microbial immunomodulators in the dysregulated cytokine patterns of AIDS patients (1997)

Macrophages and polymorphonuclear cells (PMN) play a major role as cells primarily responsive to microbial biological response modifiers (BRM). Although much attention has been given to macrophages, PMN have been relatively underinvestigated. We have recently studied the responses of PMN from HIV- and HIV+ subjects after stimulation with a powerful immunomodulatory fraction from the cell wall of Candida albicans (MP-F2) and compared this to bacterial lipopolysaccharide (LPS). Both cytokine patterns and PMN anticandidal activity were investigated. MP-F2, like LPS, was an active inducer of interleukin-8 (IL-8), tumor necrosis factor alpha (TNF-alpha), IL-6, and IL-1 beta production by PMN and monocytes from all subjects. IL-12 was also produced by MP-F2-stimulated PMN in the presence of interferon-gamma (IFN-gamma). PMN from HIV+ subjects showed increased in vitro expression of TNF-alpha and IL-6 genes as determined by semiquantitative reverse transcriptase-polymerase chain reaction. In all subjects, cytokine gene expression was strongly stimulated by MP-F2 or LPS and inhibited by IL-10. Production of IL-6 and TNF-alpha protein (measured by ELISA) was higher in PMN from HIV+ subjects in at least one of the conditions tested (unstimulated or stimulated by LPS or MP-F2). However, the amount of the C-X-C chemokine IL-8 was equal in PMN from HIV- and HIV+ subjects. PMN from HIV+ subjects were at least as active in inhibiting candide growth as PMN from HIV- controls. In both groups PMN were equally stimulated by MP-F2 and LPS. Only in severely neutropenic subjects was there some reduction in the anticandidal activity but not in cytokine responses. When appropriately stimulated by microbial BRM, PMN are active producers of pro-inflammatory and immunomodulatory cytokines. This production is not only totally preserved in HIV+ subjects but may be higher than in PMN from HIV- subjects and may be coupled with an efficient anticandida activity. We suggest that during common bacterial or fungal infections PMN may contribute to the dysregulated production of inflammatory cytokines in AIDS patients.
