Indirect Torque and Stator Reactive Power Control of Doubly Fed Induction Machine Connected to Unbalanced Power Network

The paper deals with the methods of either stator current or rotor current vector control of doubly fed induction machine connected to the unbalanced power network. Several alternative control targets, such as fixed electromagnetic torque, symmetrical stator current, or symmetrical rotor current, have been achieved. In spite of the selected target, the stator current is sinusoidal, however in some cases, it is unbalanced. The proposed vector control methods do not use separate negative sequence calculation and control. In some targets, filtration of signals is required in order to achieve symmetrical reference variables (positive sequence), which can be either stator or rotor current depending on the assumed target. Laboratory tests results have been presented in the steady state, as well as in transients. Short comparison of stator and rotor current controllers has been made on the basis of the laboratory test results.
Detection of maternal cells in human fetal blood during the third trimester of pregnancy using allele‐specific PCR amplification

Using a highly sensitive allele‐specific PCR amplification method, we have previously shown that maternal cells could be detected in all 10 cord bloods tested. This raised the question of whether maternal cells are released into cord blood during the process of delivery or whether they are already present during pregnancy. We have now used the same PCR method to detect the presence of maternal cells in nine fetal blood samples collected at different gestational ages. Maternal cells were detected in eight samples obtained between 24 and 35 weeks of gestation. They were estimated to amount between 10−4 and 10−5 of nucleated fetal blood cells. In two cases mononuclear and polymorphonuclear cell fractions were separated by Ficoll gradient centrifugation and maternal cells were detected as comparable levels in both fractions. Maternal cells could not be detected in the one fetal blood sample obtained at 20 weeks of gestation, suggesting that maternal cells could appear at detectable levels in fetal blood during the third trimester of pregnancy. These results are discussed in terms of materno‐fetal immune tolerance and of transmission of viruses (and more specifically of the human immunodeficiency virus) from mother to child.
Favorable Neurological Outcome in 7 Cases of Perinatal Intracranial Hemorrhage Due to Immune Thrombocytopenia

Neonatal intracranial hemorrhage secondary to immune thrombocytopenia has been uniformly associated with neurological sequelae in survivors. These sequelae are seizures, hydrocephalus, mental retardation, and developmental delay. We report 7 survivors of intracranial hemorrhage who were prospectively evaluated regarding their long-term outcome at a mean of approximately 5 years of age. Five children were completely normal. One was delayed in speech, and one had a ventriculoperito-neal (VP) shunt in place and a residual hemiparesis. Four children had had seizures including the two with sequelae (speech delay and hemiparesis); only the patient with the VP shunt was still taking anticonvulsant medication. This latter patient was also the only one who required special education classes in which she was maintaining her grade level. In summary, a good long-term outcome can be expected in at least some patients with neonatal intracranial hemorrhage in cases of severe neonatal thrombocytopenia caused by maternal antiplatelet antibodies. This good outcome may be a result of, and should encourage, early diagnosis and vigorous supportive care in the neonatal intensive care unit.
Multifrequency interferometer and radio continuum monitoring observations of CTA 102

This paper represents the work of several years of observation of CTA 102 with both single dish telescopes and interferometric arrays, covering wavelengths from 1.2 cm to 1.3 mm. The resolution of the maps covers an order of magnitude from 0.5 mas to 50 μ as. The images presented demonstrate the rapid structural changes in this source. These rapid structural changes correlates with the outbursts seen in the total flux, turnover frequency and in the spectral index. We have calculated the Brightness Temperatures of the components ( T B ) directly from the determined component sizes and also using the logarithmic variability amplitudes and timescales to calculate the $T_{\mathrm{B}}$s. Both the methods yielded measurements of source frame T B s no higher than ~a $\rm few\times 10^{12}$ K. We find that the observed average proper motion is ~$0.4 \pm 0.07$ mas/yr, which corresponds to an apparent transverse velocity of $11 \pm 2$ c.
Characterization of Halobacterium halobium mutants defective in taxis

Mutant derivatives of Halobacterium halobium previously isolated by using a procedure that selected for defective phototactic response to white light were examined for an array of phenotypic characteristics related to phototaxis and chemotaxis. The properties tested were unstimulated swimming behavior, behaviorial responses to temporal gradients of light and spatial gradients of chemoattractants, content of photoreceptor pigments, methylation of methyl-accepting taxis proteins, and transient increases in rate of release of volatile methyl groups induced by tactic stimulation. Several distinct phenotypes were identified, corresponding to a mutant missing photoreceptors, a mutant defective in the methyltransferase, a mutant altered in control of the methylesterase, and mutants apparently defective in intracellular signaling. All except the photoreceptor mutant were defective in both chemotaxis and phototaxis.
Expression of a Dominant Negative FGF Receptor in Developing GNRH1 Neurons Disrupts Axon Outgrowth and Targeting to the Median Eminence1

Abstract During development, neurons that synthesize and release gonadotropin-releasing hormone (GNRH1) extend their axons to the median eminence (ME) to establish neurosecretory contacts necessary for hormone secretion. Signals that coordinate this process are not known, but could involve the activation of fibroblast growth factor receptors (FGFRs) expressed on developing GNRH1 neurons. Using both whole-animal and cell culture approaches, this study examines the direct role of FGFR signaling in the extension and guidance of GNRH1 axons to the ME. In vivo retrograde labeling with fluorogold (FG) first showed a significant reduction in the projections of GNRH1 axons to the circumventricular organs (including the ME) in transgenic mice expressing a dominant negative FGF receptor (dnFGFR) in GNRH1 neurons. Using a primary GNRH1 neuronal culture system, we examined if compromised axon extension and directional growth led to the reduced axon targeting efficiency seen in vivo. Primary cultures of GNRH1 neurons were established from Embryonic Day 15.5 embryos, an age when GNRH1 neurons are actively targeting the ME. Cultured GNRH1 neurons expressing dnFGFR (dnFGFR neurons) exhibited attenuated activation of signaling pathways and reduced neurite outgrowth in response to FGF2. Further, dnFGFR neurons failed to preferentially target neurites toward cocultured ME explant and FGF2-coated beads, suggesting a defect in axon pathfinding. Together, these findings describe a direct role of FGFR signaling in the elongation and guidance of GNRH1 axons to the ME.
Digital cellular implementation of Morris-Lecar neuron model

The detailed biological neuron models such as Morris-Lecar cannot be easily implemented using conventional digital or analog Euler-based methods due to the presence of nonlinear functions and complex operations in their equations. This study presents an efficient cellular-based digital architecture for implementing Morris-Lecar neuron model. Digital hardware post synthesis results show that this hardware model is able to reproduce various responses of the biological model. The proposed architecture is not dependent on the complexity of the equations, and applies no function approximation method to deliver implementable equations. This implies that all other detailed neuron models can also be implemented by this structure. High programmability of the proposed hardware model also enables it to be applied to embedding neuromorphic hardware and real-time applications.
Deletion of microsomal prostaglandin E synthase-1 augments prostacyclin and retards atherogenesis

Prostaglandin (PG) E2 is formed from PGH2 by a series of PGE synthase (PGES) enzymes. Microsomal PGES-1−/− (mPGES-1−/−) mice were crossed into low-density lipoprotein receptor knockout (LDLR−/−) mice to generate mPGES-1−/− LDLR−/−s. Urinary 11α-hydroxy-9, 15-dioxo-2,3,4,5-tetranor-prostane-1,20-dioic acid (PGE-M) was depressed by mPGES-1 deletion. Vascular mPGES-1 was augmented during atherogenesis in LDLR−/−s. Deletion of mPGES-1 reduced plaque burden in fat-fed LDLR−/−s but did not alter blood pressure. mPGES-1−/− LDLR−/− plaques were enriched with fibrillar collagens relative to LDLR−/−, which also contained small and intermediate-sized collagens. Macrophage foam cells were depleted in mPGES-1−/− LDLR−/− lesions, whereas the total areas rich in vascular smooth muscle cell (VSMC) and matrix were unaltered. mPGES-1 deletion augmented expression of both prostacyclin (PGI2) and thromboxane (Tx) synthases in endothelial cells, and VSMCs expressing PGI synthase were enriched in mPGES-1−/− LDLR−/− lesions. Stimulation of mPGES-1−/− VSMC and macrophages with bacterial LPS increased PGI2 and thromboxane A2 to varied extents. Urinary PGE-M was depressed, whereas urinary 2,3-dinor 6-keto PGF1α, but not 2,3-dinor-TxB2, was increased in mPGES-1−/− LDLR−/−s. mPGES-1-derived PGE2 accelerates atherogenesis in LDLR−/− mice. Disruption of this enzyme retards atherogenesis, without an attendant impact on blood pressure. This may reflect, in part, rediversion of accumulated PGH2 to augment formation of PGI2. Inhibitors of mPGES-1 may be less likely than those selective for cyclooxygenase 2 to result in cardiovascular complications because of a divergent impact on the biosynthesis of PGI2.
Modular curves and arithmetic

1,190,418. Screw extruders. EGAN MACHINERY CO. 8 Aug., 1967 [29 Sept. , 1966], No. 36402/67. Heading B5A. [Also in Division F2] In a fluid thrust bearing of an extruder, fluid is supplied to a gap between an end of a thrust screw 42 and end member 56 by rotation of screw 42 in the bore 41 of barrel 40. The fluid returns to the other end of the bore 41 through passage 60. A roller bearing 58 takes the thrust at low speeds of the screw 42. In Fig. 2 an extruder has a pair of extruder screws in a barrel 17 each feeding plastics material to a die 20. Each extruder screw is connected with a respective thrust screw in barrel 40, the connected screws being coaxial but having threads of the opposite hand. The axial thrust on the extruder screws during operation is balanced by that on the thrust screws produced at the bearing. The temperature of the bearing fluid is controlled by a heating or cooling fluid flowing through a jacket around barrel 40. The bearing fluid temperature may be controlled by the speed of the extruder screws.
Effects of rapid tryptophan depletion on brain 5-HT2 receptors: a PET study

Background The mechanism by which rapid tryptophan depletion (RTD) paradigm induces depressive relapse in recently remitted patients with depression is unknown. Aims To determine the effects of RTD on brain 5-HT2 receptors using positron emission tomography (PET) and 18F-labelled setoperone. Method Ten healthy women underwent two PET scans. Each scan was done 5 h after the ingestion of either a balanced or a tryptophan-deficient amino acid mixture, and the two test sessions were separated by at least 5 days. Results The RTD decreased plasma free tryptophan levels significantly but it had no significant effects on mood. Subjects showed a significant decrease in brain 5-HT2 receptor binding in various cortical regions following the RTD session. Conclusions When taken with the evidence that antidepressant treatment is associated with a decrease in brain 5-HT2 receptors, these findings suggest that a decrease in 5-HT2 binding following RTD might be an adaptive response that provides protection against depressive symptoms.
Sea Ice: Physics and Remote Sensing

Sea Ice: Physics and Remote Sensing addresses experiences acquired mainly in Canada by researchers in the fields of ice physics and growth history in relation to its polycrystalline structure as well as ice parameters retrieval from remote sensing observations. The volume describes processes operating at the macroand microscale (e.g., brine entrapment in sea ice, crystallographic texture of ice types, brine drainage mechanisms, etc.). The information is supported by high-quality photographs of ice thin-sections prepared from cores of different ice types, all obtained by leading experts during field experiments in the 1970s through the 1990s, using photographic cameras and scanning microscopy. In addition, this volume presents techniques to retrieve a suite of sea ice parameters (e.g. ice type, concentration, extent, thickness, surface temperature, surface deformation, etc.) from space-borne and airborne sensor data. The breadth of the material on this subject is designed to appeal to researchers and users of remote sensing data who want to develop quick familiarity with the capabilities of this technology or detailed knowledge about major techniques for retrieval of key ice parameters.
Metabolic and thermoregulatory responses to exercise during the human menstrual cycle.

Metabolic and thermoregulatory responses to exercise during the human menstrual cycle. Med. Sci. Sports Exercise, Vol. 14, No. 4, pp. 270-275, 1982. Six healthy adult females with presumptively normal menstrual cycles volunteered to exercise on a bicycle ergometer on five separate days (days 2, 8, 14, 20, and 26 of the menstrual cycle; day 1 = onset of menstruation). On each experimental day each subject exercise at four submaximal exercise intensities and at an exercise intensity that elicited a peak oxygen uptake. At rest and at each exercise intensity metabolic and thermoregulatory measurements were made. There were no changes at rest or at any exercise intensity relative to cycle day in absolute oxygen uptake (l . min-1). Similarly, mean peak oxygen uptake and average work time to exhaustion were not different during the various phases of the menstrual cycle. The mean core temperature (Tre) at each exercise intensity was elevated on days 14 and 20 above that observed during flow (day 2) and the follicular phase (day 8). This implied a dissociation of metabolic responses from thermoregulatory responses to exercise during the human menstrual cycle similar to that previously observed in exercising febrile males.
SYNCHRONOUS-REFERENCE – FRAME BASED CONTROL METHOD FOR UPQC UNDER DIFFERENT LOAD CONDITIONS

A new synchronous-reference-frame (SRF)-based control method is proposed in this project . It compensate power-quality (PQ) problems through a three-phase four-wire unified PQ conditioner (UPQC) under unbalanced and distorted load conditions. The proposed UPQC system can improve the power quality at the point of common coupling on power distribution systems under unbalanced and distorted load conditions. The main problem in the power distribution system is voltage sag, voltage swell and load reactive power compensation, to compensate these problems we are using in this project a power electronic device i.e., UPQCS(Unified power quality conditioner). S means complex power. i.e., vector sum of active and reactive power. UPQC is a flexible ac transmission system. It is combination of series and shunt converters.
Heat Shock Protein 90 c-Terminal Inhibitors in Cancer Treatment

Editorial Heat shock protein 90 (Hsp90) is 90 kDa highly conserved dimeric chaperone protein in prokaryotic and eukaryotic cells and it is localized in different parts of the cell. Hsp90AA1 (inducible) and Hsp90AB1 (constitutive) are available in the cytosol; Grp94 and TRAP1 exist in endoplasmic reticulum and mitochondria; respectively. In unstressed cells, expression level of Hsp90 corresponds to 1-2% of total cellular protein, and Hsp90 is responsible for protein folding, maintenance and degradation of misfolded proteins, cell cycle control, and cellular signaling. Hsp90 is composed of three domains: N terminal domain (NTD), middle domain (MD), and C terminal domain (CTD). Hsp90 needs ATP hydrolysis energy to perform chaperone functions. NTD has ATP binding sites and ATP hydrolysis leads to large conformational changes for interaction between substrate proteins and Hsp90. CTD contains a conserved EEVD motif and the dimerization interface to regulate ATPase process and binding of co-chaperones (i.e. Hop, CHIP) in protein folding process [1-1.

Aortic stiffness: prime time for integration into clinical practice?

T he arterial system has a dual function: first, to deliver blood to the periphery and second, to transform the periodical left ventricular ejection into a continuous flow. The second (cushioning) function is accomplished through a sophisticated arterial structure, which allows the arterial system to act like an elastic buffer; part of the energy released with every heartbeat is temporarily stored during systole in the aorta and other great arteries and is then released with the elastic recoil of arteries during diastole. The vessel with the greatest cushioning capacity is the aorta, which accommodates approximately 50% of blood volume ejected during each systole. Thus, the elastic behaviour of the aorta (quantified by various measures including aortic stiffness) is of paramount importance for proper tissue perfusion and cardiovascular performance.
ULOGA BIOLOŠKE TERAPIJE U LIJEČENJU EKSTRAINTESTINALNIH MANIFESTACIJA I KOMPLIKACIJA UPALNIH BOLESTI CRIJEVA

Zahvaćenost drugih organa i organskih sustava kao i drugih autoimunih poremećaja česta je pojava u bolesnika s upalnim bolestima crijeva – javlja se u oko 35 % bolesnika (1,2). Također se čini da pojava jedne povećava rizik od razvoja drugih ekstraintestinalnih manifestacija. Može biti zahvaćen gotovo svaki organ, no ipak najčešće su zahvaćeni koštano-zglobni sustav, koža, oči, jetra i žučni sustav. Točan mehanizam nastanka ovih ekstraintestinalnih manifestacija nije do sada u potpunosti razjašnjen.
JPEG 2000 wireless image transmission system using encryption domain authentication

In this paper, we propose a wireless high resolution video transmission system with encryption and authentication. The proposed system is implemented by JPEG 2000 coding. We implement JPEG 2000 coder by GPU in CUDA which is an integrated development environment for GPU, or by JPEG 2000 codec LSI. Moreover, the authentication system can check the user information in encrypted domain using Paillier encryption. Therefore, this system is more secure than conventional systems. We show that the proposed system can achieve 4K size coding by 2.34fps with CUDA, and HD size coding by 29.98 fps with LSI codec. In addition, we demonstrate that the authentication using Paillier encryption is successful.
Suture-related Complications Following Keratoplasty: A 5-Year Retrospective Study

Purpose. To study the incidence of suture-related complications following penetrating keratoplasty (PK) and their effect on the success of corneal grafting. Methods. The records of 332 patients receiving 361 grafts in 1993 and 1994 were reviewed, and suture-related complications were recorded. These complications were divided into five groups: suture erosions, infiltrates at the suture sites, infectious keratitis, loose sutures with imminent wound dehiscence, and wound dehiscence after suture removal. Results. Occurrence rates were suture erosions, 10.8%; infiltrates, 9.4%; infectious keratitis related to sutures, 3.3%; loose sutures with imminent wound separation in need of surgical repair, 8.3%; and wound dehiscence following suture removal, 2.4%. Conclusions. Suture-related complications frequently occur after PK. Infectious keratitis and wound separations needing surgical repair may lead to loss of best-corrected visual acuity due to scarring, induced allograft reactions, and/or increased astigmatism. Recommendations for post-PK suture management are proposed.
Spaces or Scenes: Map-based Orientation in Urban Environments

Abstract Two experiments examined people's strategies when orienting with a map in outdoor scenes within unfamiliar urban environments. We investigated how the 3D visual scene and the 2D layout geometry influenced people's choices of features when matching the scene and the map, and studied the problems they encountered when doing so. Results support previous evidence that in geographically realistic contexts, visible salient landmarks bias people away from using optimal geometry-matching strategies. This implies that prediction of orientation difficulty merely from analysing the spatial layout (e.g., with space syntax isovist measures) may be highly problematic. Implications for future map design are discussed.
Young Adults’ Attitudes and Reasoning About Gender Roles in the Family Context

Although the roles of men and women in society and the workplace have undergone dramatic change, there has been comparatively less change in the family roles of men and women. This study investigated young adults’ endorsements of and reasoning about gender roles in the context of the family. Participants (N = 224) indicated their level of agreement with six different family roles and provided open-ended reasons to support their views. Social cognitive domain theory was used as a framework to interpret their open-ended reasoning. Results showed that participants applied reasoning based on ideas of morality (fairness and well-being), social conventions, and personal choice in ways that varied by participants’ gender, ethnic background (Asian or European Canadian), and the particular gender role to which they were responding. When supporting egalitarian role divisions, women were more likely to base their reasoning on morality, whereas men were more likely to rely on social conventions. In contrast, stereotypes and issues of well-being (regarding women’s roles), and social conventions (regarding men’s traditional roles) were used to support the maintenance of traditional role divisions. The results have implications for educators and policy makers and are discussed with a focus on how attitudes about family roles may be changed most effectively to increase egalitarian attitudes. Implications for the measurement of gender-role attitudes are also discussed.
HIV drug resistance

Submit Manuscript | http://medcraveonline.com with nonnucleoside reverse inhibitors (NNRTIs). Pre-therapy resistance is associated with first-line therapy failure. The most common viral mutations in HIV/AIDS patients with ARV drug resistance are M184/V, K103N, and M230L. Detection of new mutations is associated with higher HIV-1 RNA levels during persistent low-level viremia. The reduction in new HIV infections associated with earlier use of ART is predicted to decrease the risk of increasing TDR. Future TDR levels are estimated to be decreased by improving ART-regimen switching practices to the second-line and third-line regimens.
