Inertia Estimation of Wind Power Plants Based on the Swing Equation and Phasor Measurement Units (2018)

High penetration of wind power plants may have an adverse impact on power systems’ stability by reducing the inertia, and problems like frequency stability could appear due to total inertia in the system being reduced, making the power system more vulnerable to disturbances. However, most recent grid codes include an emulation inertia requirement for wind power plants, because modern wind turbines are capable of providing virtual inertia through power electronic converter controls to improve frequency stability issues. Because of this, it is necessary that the inertia estimation analyze and quantify the impact of the inertia reduction in power systems. In this paper, an implementation of a methodology for the inertia estimation of wind power plants is presented. It is evaluated through synchrophasor measurements obtained from a Real-Time Digital Simulator (RTDS) implementation, using industrial Phasor Measurement Units (PMUs). This methodology is based on the swing equation. Furthermore, a comparison of the results obtained between two professional tools RSCAD and DIgSILENT PowerFactory is performed, in order to evaluate the accuracy and the robustness of the methodology. This methodology is applied for the inertia estimation of an equivalent of the southeast zone of the Mexican power system, where there is a large-scale penetration of wind power plants. The results demonstrate that this methodology can be applied in real power systems using PMUs.

Active microwave tomographic imaging of isolated, perfused animal organs (1985)

The relative transparency of biological materials to high-frequency electromagnetic waves has encouraged the development of new systems for imaging. This report describes experiments of microwave tomography conducted on a prototype. The object to be analyzed is submerged in water and is illuminated by a plane wave. The total electric field is analyzed by a microwave camera. The recorded data are then processed numerically in order to reconstruct the image that corresponds to the distribution of equivalent currents in a defined plane of a section. Experiments have been conducted on isolated kidneys with and without perfusion. The influence of the perfusing solution temperature has also been studied. These experiments show the potential of this system, especially through the correlation between microwave images and the biological structures. They also confirm previous results concerning spatial resolution and depth of exploration. Finally, the results demonstrate the influence of temperature and support the applicability of this imaging system in non-invasive thermometry, especially for clinical hyperthermia.

Recent Advances in the Chemical Recycling of Polymers (PP, PS, LDPE, HDPE, PVC, PC, Nylon, PMMA) (2012)

recycled resin is reduced due to chain scission reactions caused by the presence of water and trace acidic impurities. Strategies for maintaining the polymer average molecular weight during reprocessing include intensive drying, reprocessing with degassing vacuum, the use of chain extender compounds, etc. 3. Chemical or Feedstock recycling (tertiary recycling) has been defined as the process leading in total depolymerization of PET to the monomers, or partial depolymerization to oligomers and other chemical substances. The monomers could subsequently repolymerized to regenerate the original polymer. 4. Energy recovery (Quaternary recycling) refers to the recovery of plastic's energy content.
The Local Structure of Turbulence in Incompressible Viscous Fluid for Very Large Reynolds' Numbers (1941)

§1. We shall denote by uα ( P ) = uα ( x 1, x 2, x 3, t ), α = 1, 2, 3, the components of velocity at the moment t at the point with rectangular cartesian coordinates x 1, x 2, x 3. In considering the turbulence it is natural to assume the components of the velocity uα ( P ) at every point P = ( x 1, x 2, x 3, t ) of the considered domain G of the four-dimensional space ( x 1, x 2, x 3, t ) are random variables in the sense of the theory of probabilities (cf. for this approach to the problem Millionshtchikov (1939) Denoting by Ᾱ the mathematical expectation of the random variable A we suppose that ῡ 2 α and (d uα /d xβ )2― are finite and bounded in every bounded subdomain of the domain G .
Liquid crystal tunable filters and polarization controllers for biomedical optical imaging (2008)

Liquid crystal (LC) devices exhibit fast and strong tuning and switching capabilities using small voltages and can be miniaturized thus have a great potential to be used with miniature optical imaging systems for biomedical applications. LC devices designed specifically for integration into biomedical optical imaging systems are presented. Using a combination of one or two LC retarders we obtained polarimetric imaging of the skin. LC tunable filters with high dynamic range and large throughput are designed for hyperspectral imaging and for spectral domain optical coherence tomography. The designs are based on several concepts both using the classical stack of retarders and using more modern designs based on single layer in a waveguide or in a Fabry-Perot cavity.
Scheduling coprocessor for enhanced least-laxity-first scheduling in hard real-time systems (2003)

Scheduling time impact on system performance increases especially when using dynamic priority algorithms, because of the enlarged computational effort at runtime. This overhead can be reduced by using dedicated hardware that does the time consuming computations necessary for scheduling. This can be a coprocessor capable of implementing dynamic scheduling algorithms which are, until now, rarely used because of their complex computations at schedule time. One of these algorithms is Least-Laxity-First (LLF). This is an optimal scheduling methodology that allows detection of time constraint violations ahead of reaching a task's deadline, but has the disadvantage of showing poor runtime behavior in some special situations ("thrashing"). In this paper, we present a universal deterministic scheduling coprocessor that implements the newly developed Enhanced Least-Laxity-First-algorithm (ELLF) which eliminates this disadvantage of LLF. Computation time of this device is rather a matter of time resolution than of the number of tasks.

Collaborative transmit diversity with adaptive radio resource and power allocation (2005)

We consider optimized collaborative transmit diversity schemes for the situation when the source and the relay know the magnitudes of all channel gains in the system. We demonstrate how one can optimally allocate not only transmit power but also the time and bandwidth used by the different nodes. Numerical examples illustrate the possible performance gain over nonadaptive collaboration.
Blockade of Leukotriene B4 Signaling Pathway Induces Apoptosis and Suppresses Cell Proliferation in Colon Cancer (2007)

We investigated whether leukotriene B(4) (LTB(4)) and its signaling pathway play an important role in the progression of human colon cancer via a direct stimulation of cancer cell proliferation. Remarkable expression of LTB(4) receptor 1 (BLT1) in human colon cancer tissues was detected by immunohistochemistry, and Western blot analysis revealed the BLT1 expression in cultured human colon cancer cell lines, Caco2 and HT29. The 5-lipoxygenase inhibitor AA-861 and LTB(4)-receptor antagonist U75302 showed negative effects on survival and proliferation of both Caco2 and HT-29 cells. The inhibition of cell proliferation is due to the apoptosis because nuclear condensation and increased annexin V expression were observed in the cells treated with AA-861 and U75302. Knockdown of BLT1 by small interfering RNA caused the suppression of BLT1 protein, resulting in the inhibition of cancer cell proliferation. Blockade of BLT1 by the receptor antagonist significantly suppresses the LTB(4)-stimulated extracellular signal-regulated kinase (ERK) activation in colon cancer cells. These results indicate that the blockade of the LTB(4)-signaling pathway induces apoptosis via the inhibition of ERK activation in colon cancer cells. The LTB(4)-signaling pathway might be a new therapeutic target for colon cancer.
The JPEG2000 standard for medical image applications (2004)

A new standard of still image compression is characterised in the context of medical applications. Wide spectrum of JPEG2000 features is analysed with respect to its application potential to improve the performance of modern medical services (i.e. telemedicine, PACS, radiology information systems, wireless personal/home health care systems). Image data security techniques, error resilience technologies, client-side interactive Region of Interest (ROI) transmission and decoding (e.g. for teleconsultation with very large radiography exams), and storage of multiple image data sets are considered in detail. Selected tests of coders realized according to parts I and II of JPEG2000 for different modality test images are presented to evaluate the compression efficacy of this standard. Exemplary results of encoding process optimisation by wavelet transform and subband decomposition selection and screen-shots of software interfaces designed for these tests are also presented.
Robertsonian translocations in wheat arise by centric misdivision of univalents at anaphase I and rejoining of broken centromeres during interkinesis of meiosis II (2005)

The mechanism of origin of Robertsonian translocations was investigated in plants monosomic for chromosome 1A of wheat and 1H(t) of Elymus trachycaulus by GISH. Chromosomes 1A and 1H(t) stayed univalent in all metaphase I cells analyzed, suggesting that Robertsonian translocations do not originate from meiotic recombination in centromeric regions with shared DNA sequence homology. At ana-/telophase I, the 1H(t) and 1A univalents underwent either chromosome or chromatid segregation and misdivided in 6-7% of the pollen mother cells. None of the ana-/telophases I analyzed had Robertsonian translocations, which were only observed in 2% of the "half tetrads" at ana-/telophase II. The frequency of Robertsonian translocations observed at ana-/telophase II corresponds well with the number of Robertsonian translocations (1-4%) detected in progenies derived from plants monosomic for group-1 chromosomes of wheat (1A, 1B, and 1D) and 1H(t) of E. trachycaulus. Our data suggest that Robertsonian translocations arise from centric misdivision of univalents at ana-/telophase I, followed by segregation of the derived telocentric chromosomes to the same nucleus, and fusion of the broken ends during the ensuing interkinesis.
Bouncer, the bouncing baby umbrella cockatoo (1988)

Of all the various species of psittacines I have kept, the genus Cacatua will probably always be my favorite. My very first cockatoo was purchased in 1981 from a pet shop, a beautiful citron hen. She was very tame and loving and I was hooked. I named her Aphrodite, as she appeared to me to be a goddess of love and beauty. Aphrodite just produced her first baby in May of 1988. This story is of my very first cockatoo baby; the traumas I went through as a novice, learning many things the hard way. I hope from this that others w i l l learn as I relate my experiences, both good and bad.
Training Direction-Discrimination Sensitivity Remediates a Wide Spectrum of Reading Skills (2007)

Background: This study investigated whether timing deficits in the motion pathways represent a core deficit in inefficient readers who are dyslexic. Methods: Inefficient and efficient readers in grades 2 and 3 in four public elementary schools were studied. Component literacy skills were measured before and after training. In the training task of interest, participants judged the direction of motion (left vs. right) of a vertically oriented sinusoidal grating, surrounded by one of five different background frequencies. The threshold contrast for direction discrimination was measured. Results: Direction discrimination improved the most for inefficient readers following training. Moreover, following training the time to complete the task decreased significantly, showing that the timing of direction discrimination improves, as does the gain. For inefficient readers, training on direction discrimination resulted in significant improvements in reading efficiency and fluency. Inefficient readers in control conditions showed minimal improvement. Conclusions: Significant improvements in reading performance were found following training on direction discrimination. This study provides evidence that timing deficits in inefficient readers represent a core deficit.
Preoperative Mobilization of Circulating Dendritic Cells by Flt3 Ligand Administration to Patients With Metastatic Colon Cancer (2000)

Flt3L is capable of mobilizing DCs into the peripheral blood of patients with metastatic colon cancer and may be associated with increases in DC infiltration in the peritumoral regions. Flt3L mobilization is associated with a trend toward increased DTH responses to recall antigens in vivo. The use of Flt3L to increase circulating DCs for cancer immunotherapy should be considered.
Functional characterization of a human receptor for neuropeptide FF and related peptides (2001)

1. Neuropeptides FF (NPFF) and AF (NPAF) are involved in pain modulation and opioid tolerance. These peptides were known to act through uncharacterized G protein-coupled receptors (GPCR). We describe here, using an aequorin-based assay as screening tool, that an orphan GPCR, previously designated HLWAR77, is a functional high affinity receptor for NPFF and related peptides. This receptor is further designated as NPFFR. 2. Binding experiments were performed with a new radioiodinated probe, [(125)I]-EYF, derived from the EFW-NPSF sequence of the rat NPFF precursor. Chinese hamster ovary (CHO) cell membranes expressing NPFFR bound [(125)I]-EYF with a K(d) of 0.06 nM. Various NPFF analogues and related peptides inhibited [(125)I]-EYF specific binding with the following rank order (K(i)): human NPAF (0.22 nM), SQA-NPFF (0.29 nM), NPFF (0.30 nM), 1DMe (0.31 nM), EYW-NPSF (0.32 nM), QFW-NPSF (0.35 nM), 3D (1.12 nM), Met-enk-RF-NH(2) (3.25 nM), FMRF-NH(2) (10.5 nM) and NPSF (12.1 nM). 3. The stimulatory activity of the same set of peptides was measured by a functional assay based on the co-expression of NPFFR, G(alpha 16) and apoaequorin. The rank order of potency was consistent with the results of the binding assay. 4. Membranes from NPFFR expressing CHO cells bound GTP gamma[(35)S] in the presence of SQA-NPFF. This functional response was prevented by pertussis toxin treatment, demonstrating the involvement of G(i) family members. 5. SQA-NPFF inhibited forskolin induced cyclic AMP accumulation in recombinant CHO cells in a dose dependent manner. This response was abolished as well by pertussis toxin pre-treatment. 6. RT -- PCR analysis of human tissues mRNA revealed that expression of NPFFR was mainly detected in placenta, thymus and at lower levels in pituitary gland, spleen and testis.
Screening for breast atypias using exfoliative cytology (1979)

A sample of 1744 self-selected, mostly asymptomatic women was used to evaluate exfoliative cytology of nipple secretions as a screening technique for breast atypias. Results indicated: 1) overall frequency of breast fluid recovery was 49%, and related to age, phase of reproductive life, parity, history of lactation and birth control pill use at the time of sampling. 2) Frequency of satisfactory smears was 36% of breast fluid specimens, and related to subject's phase of reproductive life. 3) 2.8% of all satisfactory smears exhibited atypical cells. Biopsy of 4 subjects with atypical smears indicated 3 with nonmalignant epithelial atypias and 1 with early ductal carcinoma. Follow-up of women who did not have atypical smears indicated 12/1092 (1.1%) with non-malignant epithelial atypias and none with carcinoma. 4) The number of cases of malignant (1) and nonmalignant (7) breast disease detected was close to the expected number in the population sampled (1.98 and 7.25, respectively).
Invasive breast carcinoma (2013)

The breast does not have a blood supply from a single artery. Perforating branches from the internal mammary artery supply the medial and deep parts of the breast. These branches anastomose with branches from the axillary artery and the lateral thoracic artery. Branches from the thoracoacromial trunk and some intercostal vessels supply the deeper aspects of the gland. The venous drainage of the breast generally corresponds to the arterial supply. Veins beneath the areola form an anastomotic circle (circulus venosus), which together with deeper veins carries blood to the periphery of the gland where venous outfl ow is via the internal thoracic, lateral thoracic, and upper intercostal veins.
PLANEJAMENTO AMBIENTAL COMO SUBSÍDIO PARA O ORDENAMENTO TERRITORIAL DA APA DE BALBINO-CASCAVEL-CEARÁ (2011)

As politicas ambientais ao longo do percurso historico sofreram alteracoes de acordo com a necessidade do meio ambiente, assim as unidades de conservacao referenciadas na Lei do Sistema Nacional de Unidades de Conservacao (SNUC) propoe a necessidade da realizacao do Plano de Manejo como forma de planejamento do territorio. Porem existem areas que nao se desenvolvem com o que se e proposto, a exemplo da APA de Balbino-Cacavel, CE. A Area de Protecao Ambiental de Balbino em Cascavel-CE foi estabelecida pela Lei No 479 de 21 de setembro de 1988, tendo como finalidade proteger, conservar e melhorar o meio ambiente, mantendo seu ecossistema natural alem do valor historico e paisagistico. Partindo dessas iniciativas pretende-se  propor acoes ordenadas para o territorio, para que assim os orgaos competente estabelecam o Plano de Manejo em âmbito socioambiental. Nesse sentido a Geoecologia da Paisagem permite estudar a integracao entre a natureza e a sociedade, em seus aspectos estruturais e funcionais,  tendo na teoria e metodologia subsidios para elaboracao do planejamento ambiental, sendo uma forma de gestao e ordenamento territorial, direcionado principalmente para areas propicias ao uso inadequado.
A rotating light table to measure the lustre of fibres and fabrics (2013)

The Rotating Light Table (RLT) is a light-reflective device developed to measure the surface luster of fibers in various forms - as bundles containing many parallel fibers (e.g., in top form), as small groups of parallel fibers, or even as single fibers. Such fibers may be un-dyed (white/cream), dyed, or naturally colored. The device can compare the relative luster of fiber bundles before and after undergoing surface modification. Comparing the surface luster of cotton sliver before and after mercerization exemplifies the technique. Surface reflectance profiles from < 20 parallel-mounted human hairs orientated root-to-tip, and from single black or light-colored fibers, further exemplify the precision and sensitivity of the technique.

Lateral encroachment of Ni-silicides in the source/drain regions on ultrathin silicon-on-insulator (2005)

Lateral growth of Ni silicide towards the channel region of metal-oxide-semiconductor transistors (MOSFETs) fabricated on ultrathin silicon-on-insulator (SOI) is characterized using SOI wafers with a 20-nm-thick surface Si layer. With a 10-nm-thick Ni film for silicide formation, p-channel MOSFETs displaying ordinary device characteristics with silicided p+ source/drain regions were demonstrated. No lateral growth of NiSix under gate isolation spacers was found according to electron microscopy. When the Ni film was 20 nm thick, Schottky contact source/drain MOSFETs showing typical ambipolar characteristics were obtained. A severe lateral encroachment of NiSix into the channel region leading to an increased gate leakage was revealed, while no detectable voiding at the silicide front towards the Si channel was observed.

2′-Epi-uscharin from the Latex of Calotropis gigantea with HIF-1 Inhibitory Activity (2014)

Two stereoisomeric cardenolides, uscharin (1) and a new compound, 2'-epi-uscharin (2), were isolated from the latex of Calotropis gigantea (Asclepiadaceae). Their structures were fully elucidated based on their spectroscopic data, X-ray crystallographic data and chemical evidences. Both epimers (1 and 2) exhibited strong inhibitory effects on HIF-1 activity with different magnitudes. Compound 1 showed much more potent activity than 2 and digoxin, a well-known HIF-1 inhibitor. Discrepancy in potencies between 1 and 2 revealed the contribution of a β-configuration of 2' hydroxyl moiety for HIF-1 inhibitory activity. This is a first report of the activity of HIF-1 inhibition of thiazoline ring-containing cardenolides.
