    As congenital anatomic variants of venous drainage, developmental venous anomalies (DVA) represent up to 60% of all cerebral vascular malformations. The prior term "venous angioma" is a misnomer implicating an abnormal vascular structure with an increased bleeding risk. They are often found incidentally and are hardly ever symptomatic. Their morphologic characteristics are dilated vessels in the white matter, which converge on a greater collector vein, forming the typical caput medusae. They drain into the superficial or deep venous system. The frequent association with other, potentially bleeding-prone vascular malformations is clinically relevant, in particular cavernous angioma, which might require therapeutic action. Therefore, coincident vascular lesions need to be actively sought by appropriate additional imaging techniques.

    This study was conducted to assess dynamic visual acuity (DVA) under pupil dilation. Pupil dilation may negatively affect driving performance. Thirty healthy young adults (mean age 29.4 years) with pupil dilation participated in this study as the Mydrin P group. In addition to them, 15 healthy young adults (mean age 28.5 years) without pupil dilation were enrolled as the control group. DVA was measured binocularly with free-head viewing at 0, 30, 60, 120, and 360 min after mydriatic drop instillation in both eyes. Pupil size was measured at each time. In the Mydrin P group, DVA significantly improved at 30, 60, and 120 min (ANOVA; p DVA did not significantly change at all measured times (ANOVA; p > .9). DVA was significantly (p DVA was related to the enlargement of the pupil. This study suggests that the pupil size is one factor that may affect DVA. Potential applications of this study include useful information to assess the effect of pupil dilation on driving performance.

    The Dish Verification Antenna 1 (DVA-1) is a 15m aperture offset Gregorian radio telescope featuring a rim-supported single piece molded composite primary reflector on an altitude-azimuth pedestal mount. Vibration measurements of the DVA-1 telescope were conducted over three days in October 2014 by NSI Herzberg engineers. The purpose of these tests was to measure the first several natural frequencies of the DVA-1 telescope. This paper describes the experimental approach, in particular the step-release method, and summarizes some interesting results, including unexpectedly high damping of the first mode over a narrow range of zenith angles.

    The identity of each neuron is determined by the expression of a distinct group of genes comprising its terminal gene battery. The regulatory sequences that control the expression of such terminal gene batteries in individual neurons is largely unknown. The existence of a complete genome sequence for C. elegans and draft genomes of other nematodes let us use comparative genomics to identify regulatory sequences directing expression in the DVA interneuron. Using phylogenetic comparisons of multiple Caenorhabditis species, we identified conserved non-coding sequences in 3 of 10 genes (fax-1, nmr-1, and twk-16) that direct expression of reporter transgenes in DVA and other neurons. The conserved region and flanking sequences in an 85-bp intronic region of the twk-16 gene directs highly restricted expression in DVA. Mutagenesis of this 85 bp region shows that it has at least four regions. The central 53 bp region contains a 29 bp region that represses expression and a 24 bp region that drives broad neuronal expression. Two short flanking regions restrict expression of the twk-16 gene to DVA. A shared GA-rich motif was identified in three of these genes but had opposite effects on expression when mutated in the nmr-1 and twk-16 DVA regulatory elements. We identified by multi-species conservation regulatory regions within three genes that direct expression in the DVA neuron. We identified four contiguous regions of sequence of the twk-16 gene enhancer with positive and negative effects on expression, which combined to restrict expression to the DVA neuron. For this neuron a single binding site may thus not achieve sufficient specificity for cell specific expression. One of the positive elements, an 8-bp sequence required for expression was identified in silico by sequence comparisons of seven nematode species, demonstrating the potential resolution of expanded multi-species phylogenetic comparisons.

    Small GTPases of the recently discovered Ras-dva family are specific to the Vertebrate phylum. In Xenopus laevis, Ras-dva-1 is expressed during gastrulation and neurulation in the anterior ectoderm where it regulates the early development of the forebrain and cranial placodes (Tereshina et al., 2006). In the present work, we studied the expression of Ras-dva-1 at later developmental stages. As a result, the Ras-dva-1 expression was revealed in the eye retina, epiphysis (pineal gland), hypophysis (pituitary), branchial arches, pharynx, oesophagus, stomach and gall bladder of swimming tadpoles. Additionally, we investigated for the first time the expression pattern of Ras-dva-2. This gene encodes a protein belonging to a novel sub-group of Ras-dva GTPases that we identified by phylogenetic analysis within Ras-dva family. In contrast to Ras-dva-1, Ras-dva-2 is not expressed before the swimming tadpole stage. At the swimming tadpole stage, however, Ras-dva-2 transcripts can be detected in the eye retina and brain. Later in development, the expression of Ras-dva-2 can also be revealed in the mesonephros and stomach. Copyright © 2010 Elsevier B.V. All rights reserved.

    The current study was undertaken to evaluate the clinical utility of DVA, a system for imaging the lateral spine on the Lunar Prodigy densitometer. DVA images were obtained and bone density of the lumbar spine and proximal femur measured in 297 subjects (272 women), aged 64+/-13 years. The images were classified as: normal (N) if no fractures were detected and all vertebrae between T6 and L4 were visualized, fracture (F) if any vertebra had a fracture (defined as 25% or more reduction in the vertebral height) even if some of the other vertebrae could not be visualized, and un-interpretable (U) if at least one of the vertebra between T6 and L4 could not be classified and no fractures were detected in the visualized vertebrae. A subset of 66 patients also had standard radiographs of the thoracic and lumbar spine. Compared to radiographs, DVA had a 95% sensitivity to detect fractures and 82% specificity (to exclude them). Among all 297 subjects studied, DVAs were interpretable in 87%. They were classified as N in 204 (68%), F in 55 (19%) and U in 38 (13%). The reasons for un-interpretability were: scoliosis, scapular or rib shadow, severe arthritic changes and multiple vertebral compression fracture with severe spinal deformities. Only 11% of F subjects gave a history of a vertebral fracture, and only 56% of F subjects met the BMD criteria for osteoporosis (T score DVA, a low radiation and relatively low cost "point of service" procedure, to BMD measurement provides the clinician with a more comprehensive fracture risk assessment than that afforded by clinical evaluation and BMD measurement alone.

    DVA is primarily subserved by the vestibulo-ocular reflex mechanism. Individuals with vestibular hypofunction commonly experience highly debilitating illusory movement or blurring of visual images during daily activities possibly, due to impaired DVA. Even without pathologies, gradual age-related morphological deterioration is evident in all components of the vestibular system. We examined the construct validity to detect age-related differences and test-retest reliability of DVA measurements performed during walking. METHODS: Healthy adults were recruited into 3 groups: 1. young (20-39years, n=18), 2. middle-aged (40-59years, n=14), and 3. older adults (60-80years, n=15). Randomly selected seven participants from each group (n=21) participated in retesting. Participants were excluded if they had a history of vestibular or neuromuscular pathologies, dizziness/vertigo or >1 falls in the past year. Older persons with MMSE scores 0.05). The post hoc analyses for DVA measurements demonstrated that each group was significantly different from the other two groups for Near as well as FarDVA (p<0.001-p=0.031). The effect of speed was significant for both NearDVA (p=0.012) and FarDVA (p=0.014), however, there was no age group x speed interaction (FarDVA p=0.607, NearDVA p=0.343). The ICCs for Near and FarDVA ranged between 0.85- 0.88 and 0.71-0.87, respectively. CONCLUSIONS: Differences in DVA between the three age groups were detected by using both Near and FarDVA protocols irrespective of the walking speed. Therefore, age group-specific reference values should be used for detecting malfunction. Further, consistency in walking speed is critical for comparing between studies. NearDVA at all walking speeds and FarDVA at the speed of 1.2 m/s demonstrated excellent testretest reliability. FarDVA at 0.8 m/s and 1.0 m/s demonstrated good test-retest reliability (ICCs 0.71 and 0.77, respectively).

    Within the Rh blood group, the partial D phenotype is a well known RhD variant, that induces Rh-incompatible blood transfusion and hemolytic diseases in the newborn. The partial D category DVa phenotype (DVa Kou.) results from a hybrid of RhD-CE-D transcript. We demonstrated a genomic organization of the hybrid RHD-CE-D gene leading to the DVa phenotype, and showed that the DVa gene were generated from gene conversion between the RHD and the RHCE genes in relatively small regions. This study also revealed that the presence of a new partial D associated with the DVa phenotype, which we termed the DVa-like phenotype. In this phenotype, five RHD-specific nucleotides were replaced with the corresponding RHCE-derived nucleotides on the exon 5 of the RHD gene. In addition, two variants of the mutated RHD genes at nucleotide 697 were revealed in the RhD variant samples. These results will provide useful information for future research into the diversification of the Rh polypeptides. Copyright 1999 Academic Press.

    To examine the clinical and radiologic findings of patients with developmental venous anomaly (DVA) associated with intracranial haemorrhage but unrelated to cavernoma. Computed tomography (CT) was used to obtain intracranial images from seven patients ranging in age from 6 to 51 years. Magnetic resonance imaging (MRI) was then performed on six patients, and two patients were further examined via CT angiography. Finally, digital subtraction angiography (DSA) was performed to confirm the initial diagnosis. CT showed intraparenchymal supratentorial haemorrhage in all patients. The combined imaging modalities eventually confirmed a diagnosis of arterialized DVA in four patients and arterialized DVA associated with arteriovenus malformation (AVM) in three. Two patients were managed symptomatically, two underwent radiosurgery, one underwent surgery, one underwent combined embolisation plus radiosurgery and the remaining patient underwent combined embolisation plus surgery. Two patients died, one as a result of re-bleeding, and the other due to radiation necrosis. The mean follow-up period was 33 months (6 months to 6 years) for the remaining five patients with favourable outcome. DVA associated with intraparenchymal haemorrhage, but not related to cavernoma, was confirmed. Though very rare, DVA may present with non-cavernoma-related haemorrhage in the form of arterialized DVA or DVA with AVM.

    Dynamic vibration absorbers (DVAs) with nonlinear damping are often modelled using a power-law equivalent viscous damping relationship. There is currently not a method available to predict the peak response of this type of nonlinear DVA without resorting to computationally expensive nonlinear simulations. Since the peak response of the DVA is required during the design process, it is advantageous to have a simplified method to estimate the peak response. In this study, statistical linearization is employed to represent the nonlinear damping as amplitude-dependent viscous damping and predict the rms response of the structure-DVA system. Subsequently, statistical nonlinearization is used to describe the probability density function of the DVA response amplitude. A probability density function is developed, which enables the peak response expected during an interval of time (e.g. 1-h) to be estimated from the rms response of the structure-DVA system. Higher power-law damping exponents are shown to result in smaller peak factors. Results of nonlinear simulations reveal that the model can estimate the peak structural and DVA responses with acceptable accuracy. A plot is developed to show the peak factors for nonlinear DVAs as a function of the number of system cycles for several power-law damping exponents. This plot can be used to estimate the peak response of a nonlinear DVA as a function of its rms response.

    Having reported high adherence to court-mandated disulfiram treatment, we hypothesized that other Department of Veterans Affairs (DVA) medical centers would report frequent use of this modality. Telephone interviews with DVA substance abuse clinics in 48 of the 50 states matched the national DVA frequencies. Phone survey responders reported disulfiram prescription as never/rarely 63%, sometimes 32%, and often 5%, while court-ordered disulfiram was used never/rarely 95%, sometimes 3%, and often 2%. Nationally, disulfiram prescriptions covered only 0.07% of all veterans seen. These data suggest a need for a re-evaluation of disulfiram as an underused treatment for alcohol dependence.

    A graphical user interface (GUI) has been developed which enables interactive feedback and control to the real-time diminishing variance algorithm (DVA). This interactivity allows the user to set scan parameters, view scan statistics, and view image updates during the course of the scan. In addition, the DVA has been extended to simultaneously reduce motion artifacts in three dimensions using three orthogonal navigators. Preliminary in vivo studies indicate that these improvements to the standard DVA allow for significantly improved consistency and robustness in eliminating respiratory motion artifacts from MR images, particularly when imaging the coronary arteries.

    2007-01-01

    An analysis of amino acid sequences of small GTPases of the Ras-dva family allowed us to determine the C-terminal prenylation motif, which could be responsible for the membrane localization of these proteins. We demonstrated using in vivo EGFP tracing that the Ras-dva small GTPases from Xenopus laevis embryo cells and NIH-3T3 fibroblasts are localized on both plasma membranes and endomembranes (the endoplasmic reticulum, the Golgi apparatus, and vesicles). At the same time, the replacement of the Cys residue, the SH group of which must be theoretically farnesylated, in the C-terminal prenylation motif of the Ras-dva small GTPase by the Ser residue prevented the membrane localization of the protein. These results indicate that the C-terminal prenylation site is critical for the membrane localization of small Ras-dva GTPases.

  14. Developmental Venous Anomalies (DVA): What are they really?

    2011-03-29

    The aim of this paper is to analyse the pathophysiology of 3 DVA cases from our institution, review the literature and propose a classification of these lesions. The pathophysiology of DVAs were analysed with CT perfusion (CTP), 4 dimensional dynamic computed tomography angiography (4D CTA) and catheter digital subtraction angiography. Symptomatic DVAs may be caused by associated lesions and compression of neural structures by the DVAs. The imbalance between the inflow and outflow of these lesions, including venous ischaemia, has also been postulated as a cause. Our analysis showed that increased cerebral blood flow (CBF) and cerebral blood volume (CBV) and decreased mean transit time (MTT) and time to peak (TTP) were found in DVAs with micro arteriovenous shunting. DVAs without shunting had raised MTT and TTP instead. We postulate that the arteriovenous shunting resulted in arterial steal and chronic hypoxia which could be a pathophysiological mechanism for symptomatic DVAs. CTP and 4D CTA are effective non invasive tools to study DVAs. A classification is proposed.

    Developmental venous anomaly (DVA), formally known as venous angioma, is a congenital anatomic variant of the venous drainage of the brain. Although they typically have a benign clinical course and a low symptomatic rate, thrombosis of a drainage vein may occur, leading to potentially debilitating complications. We report a unique case of spontaneous thrombosis of a posterior fossa developmental venous anomaly with cerebellar infarct in a 61-year-old man who presented with acute onset cerebellar ataxia. DVA thrombosis was well-depicted on CT and MR studies. Patient was put on anticoagulant therapy and complete recanalization was seen on follow-up imaging.

    The DVa(Hus) was previously investigated through cDNA analysis, which revealed an RHD-CE(5)-D hybrid allele. However, the 5' and 3' breakpoints remain unknown. In this article, gene recombinations between the RHD and RHCE alleles were investigated by a combination approach of a sequence-specific primer PCR (PCR-SSP) and an RHD full-length coding region sequencing method on two Chinese subjects with weak D phenotypes. The hybrid Rhesus box of each individual was also investigated through an established PCR-based method. As a result, two partial D phenotypes, DVa(Hus) and DVI type III, were identified, each carrying one hybrid RHD-CE-D allele. The two samples were also serotyped with Rh phontypes of DccEe and DCcee, respectively. Other sequencing analyses of the DVaHus sample showed that the sequence of intron 4 is identical with RHD, whereas the whole sequence of exon 5 and intron 5 is identical with RHCE except for seven polymorphisms in the intron 5. We may concluded that in the case of this Chinese DVa(Hus), the whole exon 5 and complete intron 5 of a total segment of 1801 nucleotides were replaced by RHCE suggesting that the breakpoints of the replaced region are the 5' end of the exon 5 and the 3' end of the intron 5.

  17. Ras-dva is a novel Pit-1- and glucocorticoid-regulated gene in the embryonic anterior pituitary gland.

    Glucocorticoids play a role in functional differentiation of pituitary somatotrophs and lactotrophs during embryogenesis. Ras-dva was identified as a gene regulated by anterior neural fold protein-1/homeobox expressed in embryonic stem cells-1, a transcription factor known to be critical in pituitary development, and has an expression profile in the chicken embryonic pituitary gland that is consistent with in vivo regulation by glucocorticoids. The objective of this study was to characterize expression and regulation of ras-dva mRNA in the developing chicken anterior pituitary. Pituitary ras-dva mRNA levels increased during embryogenesis to a maximum on embryonic day (e) 18 and then decreased and remained low or undetectable after hatch. Ras-dva expression was highly enriched in the pituitary gland on e18 relative to other tissues examined. Glucocorticoid treatment of pituitary cells from mid- and late-stage embryos rapidly increased ras-dva mRNA, suggesting it may be a direct transcriptional target of glucocorticoids. A reporter construct driven by 4 kb of the chicken ras-dva 5'-flanking region, containing six putative pituitary-specific transcription factor-1 (Pit-1) binding sites and two potential glucocorticoid receptor (GR) binding sites, was highly activated in embryonic pituitary cells and up-regulated by corticosterone. Mutagenesis of the most proximal Pit-1 site decreased promoter activity in chicken e11 pituitary cells, indicating regulation of ras-dva by Pit-1. However, mutating putative GR binding sites did not substantially reduce induction of ras-dva promoter activity by corticosterone, suggesting additional DNA elements within the 5'-flanking region are responsible for glucocorticoid regulation. We have identified ras-dva as a glucocorticoid-regulated gene that is likely expressed in cells of the Pit-1 lineage within the developing anterior pituitary gland.

  18. DVA as a Diagnostic Test for Vestibulo-Ocular Reflex Function

    2010-01-01

    The vestibulo-ocular reflex (VOR) stabilizes vision on earth-fixed targets by eliciting eyes movements in response to changes in head position. How well the eyes perform this task can be functionally measured by the dynamic visual acuity (DVA) test. We designed a passive, horizontal DVA test to specifically study the acuity and reaction time when looking in different target locations. Visual acuity was compared among 12 subjects using a standard Landolt C wall chart, a computerized static (no rotation) acuity test and dynamic acuity test while oscillating at 0.8 Hz (+/-60 deg/s). In addition, five trials with yaw oscillation randomly presented a visual target in one of nine different locations with the size and presentation duration of the visual target varying across trials. The results showed a significant difference between the static and dynamic threshold acuities as well as a significant difference between the visual targets presented in the horizontal plane versus those in the vertical plane when comparing accuracy of vision and reaction time of the response. Visual acuity increased proportional to the size of the visual target and increased between 150 and 300 msec duration. We conclude that dynamic visual acuity varies with target location, with acuity optimized for targets in the plane of rotation. This DVA test could be used as a functional diagnostic test for visual-vestibular and neuro-cognitive impairments by assessing both accuracy and reaction time to acquire visual targets.

  19. Optical information for car following: the driving by visual angle (DVA) model.

    2007-10-01

    The present study developed and tested a model of car following by human drivers. Previous models of car following are based on 3-D parameters such as lead vehicle speed and distance information, which are not directly available to a driver. In the present paper we present the driving by visual angle (DVA) model, which is based on the visual information (visual angle and rate of change of visual angle) available to the driver. Two experiments in a driving simulator examined car-following performance in response to speed variations of a lead vehicle defined by a sum of sine wave oscillations and ramp acceleration functions. In addition, the model was applied to six driving events using real world-driving data. The model provided a good fit to car-following performance in the driving simulation studies as well as in real-world driving performance. A comparison with the advanced interactive microscopic simulator for urban and nonurban networks (AIMSUN) model, which is based on 3-D parameters, suggests that the DVA was more predictive of driver behavior in matching lead vehicle speed and distance headway. Car-following behavior can be modeled using only visual information to the driver and can produce performance more predictive of driver performance than models based on 3-D (speed or distance) information. The DVA model has applications to several traffic safety issues, including automated driving systems and traffic flow models.

  20. Ras-dva, a member of novel family of small GTPases, is required for the anterior ectoderm patterning in the Xenopus laevis embryo.

    Ras-like small GTPases are involved in the regulation of many processes essential for the specification of the vertebrate body plan. Recently, we identified the gene of novel small GTPase Ras-dva, which is specifically expressed at the anterior margin of the neural plate of the Xenopus laevis embryo. Now, we demonstrate that Ras-dva and its homologs in other species constitute a novel protein family, distinct from the previously known families of small GTPases. We show that the expression of Ras-dva begins during gastrulation throughout the anterior ectoderm and is activated by the homeodomain transcription factor Otx2; however, later on, Ras-dva expression is inhibited in the anterior neural plate by another homeodomain factor Xanf1. Downregulation of Ras-dva functioning by the dominant-negative mutant or by the antisense morpholino oligonucleotides results in severe malformations of the forebrain and derivatives of the cranial placodes. Importantly, although the observed abnormalities can be rescued by co-injection of the Ras-dva mRNA, they cannot be rescued by the mRNA of the closest Ras-dva homolog from another family of small GTPases, Ras. This fact indicates functional specificity of the Ras-dva signaling pathway. At the molecular level, downregulation of Ras-dva inhibits the expression of several regulators of the anterior neural plate and folds patterning, such as Otx2, BF-1 (also known as Foxg1), Xag2, Pax6, Slug and Sox9, and interferes with FGF8 signaling within the anterior ectoderm. By contrast, expression of the epidermal regulator BMP4 and its target genes, Vent1, Vent2b and Msx1, is upregulated. Together, the data obtained indicate that Ras-dva is an essential component of the signaling network that patterns the early anterior neural plate and the adjacent ectoderm in the Xenopus laevis embryos.

    This study examined effects of aging, head-trunk coupling (HTcoupling) and walking speed on dynamic visual acuity (DVA) at near and far viewing distances. Ten healthy participants were recruited in 3 groups; young: 20-33 years, Older1: 65-74 years, Older2: 75-85 years. The binocular DVA was measured while walking on a treadmill at 0.75 and 1.5 m/s speeds. The optotype display was placed at 0.5 m for NearDVA and at 3.0 m for FarDVA. On randomly selected trials, HTcoupling was achieved by using a collar. A mix-factor ANOVA (age-group x HTcoupling x speed) was performed separately for the Near and FarDVA. NearDVA declined with HTcoupling (p=0.021). Additionally, NearDVA worsened at the faster speed (p< 0.001). At 1.5 m/s speed the differences between Young and Older2 groups were significant (p=0.012) and those between Older1 and Older2 were marginal (p=0.085). FarDVA declined at the faster speed (p< 0.001) with no effect of HTcoupling or age-group. NearDVA is more sensitive to normal aging process. These age-related deficits become more apparent at higher walking speeds. Effect of HTcoupling on NearDVA suggests a possible additive effect of insufficient dampening of the vertical movement of the overall head-trunk complex and inability of the linear vestibulo-ocular reflex to compensate for the consequent high discrepancy.

    The study was purposed to analyze DNA and allele structure of the partial D phenotypes D(Va) and D(VI) of the Rhesus blood group in Chinese. Through polymerase chain reaction (PCR) and direct genomic DNA sequencing, the RHD gene was detected in three weak D individuals identified serologically. The results showed that among the three weak D individuals, one was identified as partial D phenotype D(Va) (Hus) type and genotyped DccEe; another two were testified as D(VI) III type and genotyped DCcee. Moreover, the breakpoints of the replaced region by RHCE in D(Va) (Hus) were 5' end of the exon 5 and 3' end of the intron 5, and there were 7 novel polymorphisms in intron 5: 23-25(GCA)2, 98G>A, 168-169insG, 205-206insT, 494-495insA, 1256-1257insC, 1347G>T. In conclusion the whole exon 5 and intron 5 are replaced by RHCE in D(Va) (Hus) detected in Chinese.

  5. Ras-dva1 small GTPase regulates telencephalon development in Xenopus laevis embryos by controlling Fgf8 and Agr signaling at the anterior border of the neural plate

    Full Text Available We previously found that the small GTPase Ras-dva1 is essential for the telencephalic development in Xenopus laevis because Ras-dva1 controls the Fgf8-mediated induction of FoxG1 expression, a key telencephalic regulator. In this report, we show, however, that Ras-dva1 and FoxG1 are expressed in different groups of cells; whereas Ras-dva1 is expressed in the outer layer of the anterior neural fold, FoxG1 and Fgf8 are activated in the inner layer from which the telencephalon is derived. We resolve this paradox by demonstrating that Ras-dva1 is involved in the transduction of Fgf8 signal received by cells in the outer layer, which in turn send a feedback signal that stimulates FoxG1 expression in the inner layer. We show that this feedback signal is transmitted by secreted Agr proteins, the expression of which is activated in the outer layer by mediation of Ras-dva1 and the homeodomain transcription factor Otx2. In turn, Agrs are essential for maintaining Fgf8 and FoxG1 expression in cells at the anterior neural plate border. Our finding reveals a novel feedback loop mechanism based on the exchange of Fgf8 and Agr signaling between neural and non-neural compartments at the anterior margin of the neural plate and demonstrates a key role of Ras-dva1 in this mechanism.

    To determine the effects of surgical IOP reduction (trabeculectomy) on retinal blood flow parameters in glaucoma patients using Dynamic Vessel Analysis (DVA). 26 eyes of 26 patients with progressive primary open-angle glaucoma (POAG) despite maximal topical therapy were examined before and after trabeculectomy. The responses of the retinal vessels to flickering light provocation were measured with DVA the day before surgery and 4 to 6 weeks after trabeculectomy. Between 3 and 4 weeks before surgery all local therapies were stopped and a systemic therapy with acetazolamide and conservative free topic steroidal eye drops was started. In 19 patients (73%), an inadequate response to the flicker stimulation was measured preoperatively. In these patients, the maximum dilation of arteries and veins was reduced significantly as compared to healthy eyes. In this group, the maximum dilation of the arteries following the flicker provocation improved from 1.4% before to 3.8% following trabeculectomy (p<0.01). In retinal veins, this parameter increased from 3.1% to 4.6% (p<0.05). In the 7 patients whose arterial and venous reactions to flickering light provocation preoperatively did not differ from healthy eyes, there was no significant change after surgery. The initial baseline values of arteries and veins (MU) did not deviate significantly in both groups. POAG patients with progressive disease and impaired vascular regulation profit from IOP lowering trabeculectomy concerning vascular reactivity and dilative reserve, indicating a possible improvement of retinal perfusion following effective IOP control. Future studies with long-term follow-up must determine the clinical importance of these findings for the treatment of glaucoma patients.

    This paper will give an overview of the unique mechanical and optical design of the DVA-1 telescope. The rim supported carbon fibre reflector surfaces are designed to be both low cost and have high performance under wind, gravity, and thermal loads. The shaped offset Gregorian optics offer low and stable side lobes along with a large area at the secondary focus for multiple feeds with no aperture blockage. Telescope performance under ideal conditions as well as performance under gravity, wind, and thermal loads will be compared directly using calculated radiation patterns for each of these operating conditions.

  9. Extraction of Structural System Matrices from AN Identified State-Space System Using the Combined Measurements of Dva

    A time domain method for the extraction of the structural system matrices (mass, damping and stiffness matrices) from an identified state-space system is proposed in this paper using the combined measurements of displacement, velocity and acceleration (DVA) together with the input excitations. The method is based on the invariance of continuous-time Markov parameters. An explicit expression of the relationship between the continuous-time Markov parameters, the structural system matrices, and the influence matrices for output DVA as well as the input force has been derived. The determination of structural system matrices is also valid when only the displacement, velocity or acceleration responses are measured. In this paper, the equivalent state system matrices are obtained by an algorithm, which combines the eigensystem realization algorithm (ERA) and the autoregressive with exogeneous (ARX) model. The ARX model provides the necessary discrete-time Markov parameters from the measured input and output data, and then the equivalent state system matrices are identified from discrete-time Markov parameters by using the ERA. A lumped mass model with three degrees of freedom is employed to illustrate the accuracy and feasibility of the presented method.

    2014-12-01

    Full Text Available No contexto da discussão sobre a evidenciação de informações contábeis de ser tratada de forma voluntária ou obrigatória, um dos argumentos favoráveis à obrigatoriedade consiste no caráter menos verificável da informação voluntária, em razão de não ser submetida a procedimentos de confirmação mais rigorosos, estando sujeita a vieses e a depender do julgamento de seus investidores. De outra parte, argumentos contrariam tal visão, no sentido de que incentivos econômicos e informacionais seriam suficientes para divulgar informações contábeis de forma eficiente. Neste sentido, a pesquisa investigou em que medida a obrigatoriedade de divulgação da DVA, instituída pela Lei nº 11.638/07, pode ter impactado a propriedade informacional de indicadores financeiros de análise da geração e da distribuição do valor adicionado. A amostra da pesquisa foi composta por 81 companhias listadas na BM&FBOVESPA, que divulgavam a DVA voluntariamente antes do advento da nova legislação contábil. O estudo envolveu os períodos de 2005 a 2007, antes da obrigatoriedade, e 2008 a 2012, após a obrigatoriedade de divulgação. Os dados foram obtidos no sítio da BM&FBOVESPA e foram submetidos a testes paramétricos e não paramétricos de diferença entre médias e a análise por regressão logística. Os resultados apontaram haver mudanças estatisticamente significantes em apenas dois dos indicadores analisados que relacionam geração de valor adicionado e receita e que mostram a parcela do valor adicionado destinada a acionistas. Pode-se inferir, assim, que o processo regulatório adotado na contabilidade brasileira não afetou de forma generalizada os números divulgados pela DVA.

    Developmental venous anomalies (DVAs) are common congenital venous drainage anomalies. Although they typically have a benign clinical course and a low symptomatic rate, thrombosis of a drainage vein may occur, leading to potentially debilitating complications. We report imaging findings of posterior fossa DVA with a thrombosed drainage vein in a patient with nonhemorrhagic cerebellar infarct. We also review the relevant literature on the subject.

    Clinical epidemiology studies suggest the majority of lower limb amputations were preceded by a minor traumatic event, often footwear-related, and lower limb ulcers. To reduce foot trauma and ulcers, the diabetic patient with foot insensitivity has unique footwear needs. To address these needs for patients not requiring custom shoes, the DVA/Seattle Footwear System was developed. The six components of this system include: 1) a specially designed shoe last based on the geometry of the diabetic foot and research findings on foot regions at highest risk of ulceration, 2) a depth-inlay shoe, "Custom Stride by PRS," designed to be paired with either a custom-fabricated cork insole or a preformed polyurethane insole, 3) a laser digitizing system that captures 3-D plantar foot contours, 4) DVA/Seattle ShapeMaker software adaptation for modifying plantar surface contours and applying free-form and template modifications to increase or relieve loading, 5) software that translates files into code used by a milling machine to define the cutting path and carve cork blockers into custom insoles, and 6) a preformed polyurethane insole thicker than a typical insole to accommodate the extra volume and the interior dimensions of the shoe. A 6-month pilot cross-over trial of 24 diabetic male veterans without prior foot ulcers was conducted to determine the feasibility of producing, and the safety of wearing, these depthinlay shoes and both types of insoles. During the first 4 weeks, patients were assigned to the study shoes and one type of insole. During the next 4 weeks, they wore the other type of insole, and during the final 4 months, they chose which pair of insoles to wear with the study shoes. Over 150 person-months of footwear observation revealed no breaks in the cutaneous barrier with use of either cork or polyurethane insoles and the study shoes. Patient compliance with the footwear was 88%. Patients were highly satisfied with the appearance, stability, and comfort of the

    Full Text Available Pri ispitivanju modela u "rafalnom" aerotunelu sa prekidnim dejstvom T-38, na Mahovim brojevima većim od 2, moraju se uzeti u obzir prelazne pojave koje se javljaju na početku i na kraju rada aerotunela. To su stanja kada su model i aerovaga izloženi velikim aerodinamičkim silama i momentima. Ova kombinovana opterećenja mogu oštetiti modele i aerovage, pa bi bilo potrebno unapred znati kolike se vrednosti očekuju za pojedine konfiguracije modela, kako bi se izvršio pravilan izbor aerovage i odgovarajućih materijala za izradu modela. U tu svrhu postoje dijagrami koji pružaju mogućnost procene ovih opterećenja. Dijagrami su dobijeni na osnovu ispitivanja nekoliko različitih modela na Mahovim brojevima većim od 2. U radu su prikazana merenja prelaznih opterećenja na još dva modela, a rezultati su upoređeni sa već postojećim dijagramima. / The T-38 wind tunnel is a blow down, intermittent-run type of wind tunnels. During model testing in the this type of wind tunnels, at Mach numbers higher than 2, transient loads which appear during the starting and stopping of the wind tunnel runs must be taken into consideration. These are the conditions when a model and the wind tunnel balance are exposed to large aerodynamic forces and moments. These combined loads can damage models and wind tunnel balances, and, for this reason, it is very important to determine them in advance for any particular model configuration so that an appropriate wind tunnel balance and materials for model manufacturing can be chosen. For that purpose there are graphs which give possibilities to estimate these loads. The graphs are based on experiments with a number of different models at Mach numbers higher than 2. This paper gives the measurements of transient loads on two more models and the results are compared with the already existing graphs.

    Blood donors whose red blood cells (RBCs) exhibit a partial RhD phenotype, lacking some D epitopes, present as D+ in routine screening. Such phenotypes can exhibit low-frequency antigens (LFAs) of clinical significance. The aim of this study was to describe the serologic and genetic profile for a blood donor with an apparent D+ phenotype carrying a variant RHD gene where D Exons 5 and 6 are replaced by RHCE Exon (5-6). Anti-D monoclonal antibodies were used to characterize the presentation of RhD epitopes on the RBCs. RHD exon scanning and DNA sequencing of short- and long-range polymerase chain reaction amplicons were used to determine the RHD structure and sequence. Extended phenotyping for LFAs RH23 (D(W) ) and Rh32 was performed. The donor serology profile was consistent with partial RhD epitope presentation. The donor was hemizygous for an RHD variant allele described as RHD*D-CE(5-6)-D hybrid. The RHCE gene insert is at least 3.868 kb with 5' and 3' breakpoints between IVS4 + 132-c.667 and IVS6 + 1960-IVS6 + 2099, respectively. The sequence for this hybrid was assigned GenBank Accession Number KT099190.2. The RBCs were RH23 (D(W) )+ and Rh32-. A novel RHD*D-CE(5-6)-D hybrid allele encodes a partial RhD epitope and carries the LFA RH23 (D(W) ). This and the epitope profile resemble the partial DVa phenotype. Given that RBCs from this individual lack some RhD epitopes, there is an alloimmunization risk if the donor is exposed to D+ RBCs. Conversely, transfusions of RH23 (D(W) )+ cells to RH23 (D(W) )- recipients also pose an alloimmunization risk. © 2016 AABB.

    Full Text Available This study explores the fundamental traits of Adorno’s conceptual understanding of modernity. In Czech sociology, there has not been a serious discussion of Adorno’s seminal oeuvre, this article aims to fill that gap. The aim is to reconstruct the very basis of Adorno’s sociological method: firstly, the essay turns its attention to the historically specific mode of subsumption of human action to the conceptual totality of class domination. In this process, an individual adopts a positive identity within which its suppressed, ontologically negative complement – its dynamic non-identity, persists. Secondly, the study deals with Adorno’s derivation of the concept of social essence. In this respect, he draws on Marx’s Capital, but Adorno’s critical reading introduces an important conceptual innovation: under the conditions of Keynesianism, Adorno challenges the validity of Marx’s theorization of law-like objectivity of value and replaces it with the concept of exchange as the universal model of social activity. However, the study argues that Adorno ’ s reconstruction of Marx’s critique of political economy has reified Keynesian management of the capitalist economy.

    Full Text Available A new mode of religious conflict has emerged in Indonesia following the fall of the old regime in the country. The conflict in point is that between the fundamentalists and the liberals, one that means that the nuance of the conflict is no longer organizational any more than it is ideological. We now rarely hear about the conflicts between the traditionalists and the modernists, just as we now rarely are capable of differentiating their basic tenets. The difference between the two has now become to a large extent vague. In the meantime, conflicts are now taking place between the fundamentalists and the liberals on almost regular basis. Hence, we hear the conflict for example between the FUUI and Ulil Abshar Abdalla who received death threat from the afro-mentioned organization. And also the so-called Monas Tragedy, which for some reflects the real tension between the two currents of thought. This paper is designed to analyze this conflictual phenomenon and the implication that may emerge thereof by using the Poststructural theory, which is the continuation of the structuralist theory of Levi-Strauss. What we mean by the Post-structural theory is that which is developed by Michel Foucault (d. 1984 where he speaks of the archeology of knowledge and the genealogy of power. In Foucault’s theory, the former is to do with the organization of documents, their classification, their distribution and management in an orderly manner so as to enable us to differentiate between which are relevant and which are not. This theory is also about describing the so-called relations among elements of social phenomena. The latter in the meantime is to do with the analysis of the historical relationship between power and discourse. It concerns with the analysis of the trajectories of a discourse and its practices, and its relationship with what he calls the regime of truth that claims to have the pseudonaturalistic and global implication. This theory deals with the mode of relationship between these two domains. Hence, while this paper is mainly concerned with the religious thought, it is inevitably related to the notion of politics and power.

Methodology/methods: First we outline the principal theories of the statement of comprehensive income, secondly we concentrate the research to obtain the empirical data. The research is developed in the following steps: selection of the companies surveyed; selection of the documents to be analysed; election of the empirical aspects to be studied. Scientific aim: The aim of the research is to define which format has been adopted by companies listed on the Czech Republic Stock Exchange for the new Income Statement to be prepared according to the International Accounting Standards – IAS 1 revised in 2007. In particular, we examine the Consolidated Financial Statements 2010 published online. Findings: This article illustrates the two choices that have the companies to present items of net income, items of other comprehensive income and total comprehensive income: they can create one continuous statement of comprehensive income or two separate consecutive statements. Conclusions: The results show that the Czech financial statements have not a firms’ propensity to separate the section of the income statement in two statements rather than to integrate it into a single one, while the reclassification of the income statements privileges the reclassification by nature.

The model is verified using the post-Soviet Solntsevskaya and Chechenskaya mafias. This is accomplished by using case study analysis and basic descriptive/analytical methodology with an implicit comparative approach. The basic typologies used come from the Anglo-American academic environment, and the main goal of the study is to explore their application to the post-Soviet region.

    Full Text Available William Shakespeare’s “Romeo and Juliet” reveals modern feelings – love and friendship – and their sociogenesis. Love and friendship emerge here as the feelings of a modern person. “Don Quixote of La Mancha”, the great novel by Miguel de Cervantes Saavedra, to this day keeps providing new insights and hot moral and philosophical issues for debate. “Don Quixote” is closely related to the great paradoxes of life: how to sustain our moral code in a world where morality is vanishing; how to sustain noble-mindedness and noble behaviour in a world that mocks and despises an individual precisely because he tries to sustain such behaviour. The novel depicts a dramatic crossroads of two epochs – the end of the Middle Ages and the beginning of modern times. In doing so, it offers philosophical, moral and political implications for societal existence: the loss of the moral code of chivalry and the end of medieval idealism. The psychogenesis and sociogenesis of the most intimate aspects of human exchanges – love and friendship – is approached, in the article, from the perspective of the history of consciousness.

    Dynamic visual acuity (DVA) thresholds are among the few visual functions predictive of automobile crashes. DVA is also sensitive to alcohol and aging. However, measuring DVA is awkward because there is no standardized, efficient, flexible apparatus for DVA assessment. In this project, we developed a prototype of an automated, portable DVA system using a low-energy laser, and we compared this laser DVA with the traditional device in two within-subjects, repeated measures designs. The two studies included 48 participants (22 males and 26 females with an average age of 18.33 years). The most important findings were that: (1) retest reliabilities of the two DVA devices were comparable and higher with the laser; (2) average correlations between the two devices were r=0.62 (pDVA laser device can be developed to measure the same construct as the more traditional bulky DVA device.

    To determine the feasibility of the dynamic visual acuity test (DVA) in children who are preschoolers. Thirty-three preschoolers [3 years old (n = 11), 4 years old (n = 6), 5 years old (n = 8), and 6 years old (n = 8)], performed a static visual acuity test (SVA), a passive horizontal DVA (hDVA) at 1 and 2 Hz, and a DVA on treadmill at three age-specific walking speeds (slow/medium/high). The DVA scores, the difference between SVA and hDVA, were used to determine false positive results. The SVA was performed by 31/33 children, the hDVA and DVA on treadmill at slow and medium speed by 27/33 and the DVA on treadmill at high speed by 25/33. Except for one 5 years old, all drop-outs were 3 years old. The hDVA at 2 Hz was administered in only six children because of difficulties with focusing on reading the symbols at this frequency. False positive results for the hDVA at 1 Hz were found in 3/27 children, all 3 years old, and 2/6 for the hDVA at 2 Hz. The DVA on treadmill seems useful for preschoolers from age 5, but this should be further investigated in children with underlying pathologies.

    Full Text Available The current article introduces the issue of race and racism in the United States of America with focus on two specific contemporary concepts that have a big attention and have formed the discussion in the last years. The first one is laissez-faire racism from Lawrence D. Bobo who stresses the reluctance of government and political parties to engage in racial questions. The second one is concept of white privilege of Peggy McIntosh who points at advantages and privileges of white race. Both concepts attempt to raise awareness about still present racial discrimination in the United States of America, although in the last years this topic has begun to be perceived as clichet and for some the problem is considered to be solved.

    To investigate the effect of altering testing position on dynamic visual acuity (DVA) in vestibulopathic adults. Quasiexperimental research. Outpatient vestibular program. Twelve vestibulopathic adults with impaired DVA in the sitting position. DVA scores were collected during (1) sitting, (2) standing comfortably, and (3) semitandem standing as subjects viewed a vision (E) chart 3.48 m in front of them. DVA was obtained as the head was passively moved by the evaluator at a frequency of 1.5 Hz in both horizontal and vertical directions. A further subgroup of subjects (n=5) was retested after performing the "viewing x1" gaze stability home exercise four times daily (1 minute duration in the horizontal direction while sitting) for 2 months. Noncomputerized DVA score. The DVA score remained constant independent of testing position as the Friedman test did not reveal any significant differences in the DVA scores in the horizontal or vertical direction. Subjects who improved after performing the viewing x1 exercise in the horizontal direction in the sitting position tended to have the same improvement in DVA in all three positions. The results of this study show that DVA score is independent of testing position. This is clinically important since it shows that the results of DVA testing in one position are valid for other positions and that subjects can be trained to improve their DVA in a sitting posture while having carry-over effects to other, more challenging postures.

    Developmental venous anomalies (DVAs) are congenital anatomical variants of normal venous drainage of normal brain. Although DVAs are often discovered on the occasion of a seizure, their involvement in epilepsy is poorly studied. Our objective was to determine whether DVA can cause seizures, in the cases where there is no associated lesion, including no cavernoma or dysplasia. Based on clinical history, cerebral MRI, EEG recording, and 18 F-FDG PET, we report 4 patients with DVA revealed by seizures. The first patient had a convulsive seizure caused by a hemorrhagic infarction due to thrombosis of her DVA. The second patient had a left temporo-parietal DVA next to a nonspecific lesion, possibly a sequelae of a venous infarction. The last two patients disclosed an isolated and uncomplicated DVA with a concordant epileptic focus confirmed on ictal video EEG recording. We reviewed literature and identified 21 other published cases of seizures caused by complications of a DVA and 9 patients that may have a direct link between epilepsy and an isolated and uncomplicated DVA. Seizures are linked to a DVA in two main situations: presence of an associated epileptogenic lesion, such as cavernoma or dysplasia, and occurrence of a complication of the DVA. Before concluding that a seizure is caused by a DVA, it is essential to perform full MRI protocols to search them. It remains rare and uncertain that isolated and uncomplicated DVA can cause seizures. In this last situation, physiopathological processes are probably different in each patient.

  8. Health professionals responding to men for safety (HERMES): feasibility of a general practice training intervention to improve the response to male patients who have experienced or perpetrated domestic violence and abuse.

    To evaluate a training intervention for general practice-based doctors and nurses in terms of the identification, documentation, and referral of male patients experiencing or perpetrating domestic violence and abuse (DVA) in four general practices in the south west of England. Research suggests that male victims and perpetrators of DVA present to primary care clinicians to seek support for their experiences. We know that the response of primary care clinicians to women patients experiencing DVA improves from training and the establishment of referral pathways to specialist DVA services. The intervention consisted of a 2-h practice-based training. Outcome measures included: a pre-post, self-reported survey of staff practice; disclosures of DVA as documented in medical records pre-post (six months) intervention; semi-structured interviews with clinicians; and practice-level contact data collected by DVA specialist agencies. Results show a significant increase in clinicians' self-reported preparedness to meet the needs of male patients experiencing or perpetrating DVA. There was a small increase in male patients identified within the medical records (6 pre- to 17 post-intervention) but only five of those patients made contact with a specialist DVA agency identified within the referral pathway. The training increased clinicians' confidence in responding to male patients affected by DVA. The increase in recorded identification of DVA male patients experiencing or perpetrating DVA was small and contact of those patients with a specialist DVA support service was negligible. We need to better understand male help seeking in relation to DVA, further develop interventions to increase identification of male patients experiencing or perpetrating DVA behaviours, and facilitate access to support services.

    Some studies reported that cerebral developmental venous anomaly (DVA) is often concurrent with cavernous malformation (CM). But there is lack of statistical evidence and study of bulk cases. The factors associated with concurrency are still unknown. The purpose of this study was to determine the prevalence of concomitant DVA and CM using observational data on Chinese patients and analyze the factors associated with the concurrency. The records of all cranial magnetic resonance imaging (MRI) performed between January 2001 and December 2012 in Beijing Tiantan Hospital were reviewed retrospectively. The DVA and CM cases were selected according to imaging reports that met diagnostic criteria. Statistical analysis was performed using the Pearson chi-square statistic for binary variables and multivariable logistic regression analysis for predictors associated with the concurrent CM. We reviewed a total of 165,230 cranial MR images performed during the previous 12 year period, and identified 1,839 cases that met DVA radiographic criteria. There were 205 patients who presented concomitant CM among the 1,839 DVAs. The CM prevalence in DVA cases (11.1%) was significantly higher than that in the non-DVA cases (2.3%) (PDVA. There is a higher chance of concurrent CM with DVA when the DVA has three or more medullary veins in the same MRI scanning section, when the DVA is infratentorial, and when there are multiple DVAs. When diagnosing DVA cases, physicians should be alerted to the possibility of concurrent CM.

    The standard type of dynamic vibration absorber (DVA) called the Voigt DVA is a classical model and has long been investigated. In the paper, we will consider an optimization problem of another model of DVA that is called three-element type DVA for damped primary structures. Unlike the standard absorber configuration, the three-element DVA contains two spring elements in which one is connected to a dashpot in series and the other is placed in parallel. There have been some studies on the design of the three-element DVA for undamped primary structures. Those studies have shown that the three-element DVA produces better performance than the Voigt DVA does. When damping is present at the primary system, to the best knowledge of the authors, there has been no study on the three-element dynamic vibration absorber. This work presents a simple approach to determine the approximate analytical solutions for the H∞ optimization of the three-element DVA attached to the damped primary structure. The main idea of the study is based on the criteria of the equivalent linearization method in order to replace approximately the original damped structure by an equivalent undamped one. Then the approximate analytical solution of the DVA's parameters is given by using known results for the undamped structure obtained. The comparisons have been done to verify the effectiveness of the obtained results.

    We evaluated the mid-term outcome of distal venous arterialization (DVA) and the role of a combined free flap as a bridgehead for blood supply. In the past 5 years, nine patients with extensive tissue loss and lacking graftable distal arteries underwent DVA. These consisted of four primary DVAs, three combined DVA and free flap procedures, and two adjuvant DVAs for hemodynamically failed distal bypasses. After nine primary DVAs, three redo DVAs were performed for early failure. Etiologies were four Buerger disease and five arteriosclerosis obliterans, including three dialysis patients. Among the nine DVA cases, there were five primary failures: two underwent amputation, two had successful redo DVA, and the remaining one did not require redo DVA. Primary patency, secondary patency, and limb salvage rates were 44.4%, 55.6%, and 77.8%, respectively. The postoperative period was 1-36 months (median 12). Angiography demonstrated DVA was effective in the early period, and development of collaterals or a capillary network from the free flap replaced the DVA function in the intermediate period. DVA can be effective as a procedure for limb salvage in patients without graftable distal arteries, and a combined free flap is effective and functions as a bridgehead for blood supply to the ischemic zone.

    Deer velvet antler (DVA) is one of the most popular medicines in China. Numerous studies have demonstrated that velvet antler possess biological effects. However, data regarding its anti-migration activity on prostate cancer is scarce. In this study, we investigated the inhibitory effect of top DVA (T-DVA) on the expression of prostate-specific antigen (PSA) and migration-related genes in the human prostate cancer cell, LNCaP. The T-DVA down-regulated the expression of PSA. In addition, the Radius(TM) assay revealed that T-DVA inhibited the migration behavior of prostate cancer cells. Furthermore, the expression of matrix metalloproteinase (MMP)-9 and vascular endothelial growth factor (VEGF) was also decreased with T-DVA. On the contrary, T-DVA increased the tissue inhibition of metalloproteinase (TIMP)-1 and (TIMP)-2. Taken together, our findings indicate that the T-DVA possesses anti-migration activity on prostate cancer cells. This is the first study of DVA to report the anti-migration activity on prostate cancer.

    This prospective randomized study reported early results of the treatment of 36 unreconstructable patients with critical lower limb ischemia. The patients were divided into two groups: 12 were treated with distal venous arterialization (DVA) and 24 were conservatively (CT) using antiplatelet drugs. There were seven men and five women with an average age 64.3 ± 9.9 in DVA and 13 men and 11 women with a average age 67.1 ± 10.8 in CT groups of patients. The aim of this study was to estimate the validity of DVA as the limb salvage procedure. During the period of monitoring, morbidity and mortality rates were 50 and 0 per cent at DVA versus a mortality rate in the CT group of 33.3 per cent (P DVA was 4.8 ± 3.9 months (range, 1 to 14 months) versus 4.9 ± 2.4 months (range, 1 to 9 months) for the CT group (P > 0.05). Graft patency was 83.3 per cent with two early graft thromboses. There were significant differences between the two groups in limb salvage (91.7% DVA vs 12.5% CT, P DVA vs 8.3% CT, P DVA vs 0% CT, P DVA may improve the outcome of the treatment of the patients for whom the conventional bypass procedure mainly was not possible.

    A passive dynamic vibration absorber (DVA) moving along a pendulum can cause the nonlinear Coriolis damping to reduce the pendulum swing. This paper proposes a simple semi-active on-off damping controller to improve the passive Coriolis DVA. The aim of the on-off damping control is to amplify the DVA resonance motion to increase the energy dissipated. Moreover, the paper finds the analytical solution of the harmonic vibration of semi-active controlled system. The accuracy of the analytical formulas and the superior performance of the semi-active DVA are verified by numerical simulations.

  1. Help-seeking amongst women survivors of domestic violence: a qualitative study of pathways towards formal and informal support.

    Informal and formal support for women experiencing domestic violence and abuse (DVA) can improve safety and health outcomes. There has been little qualitative work on the role of both pathways to support and women's experiences of disclosing their experience of DVA in different contexts. This qualitative study used repeat interviews with women survivors of DVA to explore their pathways to support and their experiences of barriers and facilitators to disclosure and help-seeking. Thirty-one women seeking help from specialist DVA agencies in the UK were interviewed twice over 5 months. Women recounted long journeys of ambivalence, often only disclosing abuse after leaving the perpetrator. Access to specialist support rarely came via general practitioners, despite high levels of consulting for anxious and depressed feelings, and was more often facilitated by police or housing agencies following a crisis such as assault. Informal disclosure only led to specialist help if the family member or friend themselves had experience or knowledge of DVA. Women experiencing DVA need earlier access to specialized DVA services. Many women needed an 'enabler' to facilitate access, but once this contact was made, disclosure to other professionals or to family and friends was legitimized in the eyes of the women. Safely accessible publicity about DVA services and an appropriate response from social and health-care professionals should be promoted, including support for women disclosing DVA to take action on the information they receive about services. © 2014 John Wiley & Sons Ltd.

    Dynamic visual acuity (DVA) is defined as the ability to discriminate the fine parts of a moving object. DVA is generally better in athletes than in non-athletes, and the better DVA of athletes has been attributed to a better ability to track moving objects. In the present study, we hypothesized that the better DVA of athletes is partly derived from better perception of moving images on the retina through some kind of perceptual learning. To test this hypothesis, we quantitatively measured DV...

    Background Women experiencing domestic violence and abuse (DVA) are more likely to be in touch with health services than any other agency, yet doctors and nurses rarely ask about abuse, often failing to identify signs of DVA in their patients. Aim To understand women’s experience of disclosure of DVA in primary care settings and subsequent referral to a DVA advocate in the context of a DVA training and support programme for primary care clinicians: Identification and Referral to Improve Safety (IRIS). Design and setting A service-user collaborative study using a qualitative study design. Recruitment was from across IRIS trial settings in Bristol and Hackney, London. Method Twelve women who had been referred to one of two specialist DVA advocates (based at specialist DVA agencies) were recruited by a GP taking part in IRIS. Women were interviewed by a survivor of DVA and interviews were recorded and transcribed verbatim. Analysis was thematic using constant comparison. Results GPs and nurses can play an important role in identifying women experiencing DVA and referring them to DVA specialist agencies. GPs may also have an important role to play in helping women maintain any changes they make as a result of referral to an advocate, by asking about DVA in subsequent consultations. Conclusion A short time interval between a primary care referral and initial contact with an advocate was valued by some women. For the initial contact with an advocate to happen as soon as possible after a primary care referral has been made, a close working relationship between primary care and the third sector needs to be cultivated.

    Hemifacial spasm (HFS) is caused by tortuous offending vessels near the facial nerve root exit zone. However, the definitive mechanism of offending vessel formation remains unclear. We hypothesized that vascular angulation and tortuosity, probably caused by uneven vertebral artery blood flow, result in vascular compression of the facial nerve root exit zone. The authors observed two anatomical characteristics of the vertebrobasilar arterial system in 120 subjects in the surgical group and 188 controls. The presence of the dominant vertebral artery (DVA) and laterality of the vertebrobasilar junction (VBJ) were observed. We also analyzed the morphological characteristics of the surgical group showing the presence of DVA. The morphological characteristics were classified into three types: type I had the VBJ and DVA on the same side, type II had the VBJ within 2 mm of the midline, and type III had the VBJ opposite the DVA. The DVA was more prevalent in the surgical group than in the control group (71 % versus 54 %, P DVA on the left (P DVA on the right (P DVA, which corresponds with the laterality of the HFS. In the surgical group with the DVA and HFS on the same side, type I was predominant, but in the surgical group with a contralateral DVA and HFS, type III was predominant. The presence of a DVA and shifting of the VBJ on the same side plays a role in the angulation and tortuosity of vessels in the perivertebrobasilar junction, resulting in neurovascular compression of the facial nerve root exit zone and thereby causing HFS.

    Cerebral developmental venous anomaly (DVA) is considered a benign anatomical variant of parenchymal venous drainage; it is the most common vascular malformation seen in the adult brain. Despite its assumed congenital origin, little is known about DVA in the neonatal brain. We report here the first cohort study of 14 neonates with DVA. Fourteen infants (seven preterm) with DVA diagnosed neonatally using cranial ultrasound (cUS) and magnetic resonance imaging (MRI) from three tertiary neonatal units over 14 years are reviewed. DVA was first detected on cUS in 6 and on MRI in 8 of the 14 infants. The cUS appearances of DVA showed a focal fairly uniform area of increased echogenicity, often (86 %) adjacent to the lateral ventricle and located in the frontal lobe (58 %). Blood flow in the dilated collector vein detected by Doppler ultrasound (US) varied between cases (venous flow pattern in ten and arterialized in four). The appearance on conventional MRI was similar to findings in adults. Serial imaging showed a fairly constant appearance to the DVAs in some cases while others varied considerably regarding anatomical extent and flow velocity. This case series underlines that a neonatal diagnosis of DVA is possible with carefully performed cUS and MRI and that DVA tends to be an incidental finding with a diverse spectrum of imaging appearances. Serial imaging suggests that some DVAs undergo dynamic changes during the neonatal period and early infancy; this may contribute to why diagnosis is rare at this age. (orig.)

    Dynamic visual acuity (DVA) is a relatively independent parameter for evaluating the ability to distinguish details of a moving target. The present study has been designed to discuss the extent to which age-related cataract impacts DVA in elderly individuals and to determine whether it could be restored after bilateral phacoemulsification combined with intraocular lens implantation surgery. Twenty-six elderly cataract patients scheduled for binocular cataract surgery and 30 elderly volunteers without cataract were enrolled in the study. DVA at 15, 30, 60 and 90 degree per second (dps) was assessed, and velocity-dependent visual acuity decreases between consecutive speed levels were calculated. Compared with the control group, the patient group exhibited significantly worse DVA performance at all speed levels (pDVA performance at every speed level in the patient group clearly improved (pDVA was more pronounced than the improvement in static visual acuity (p15 dps = 0.001 and pDVA was more severe than its effects on static visual acuity. After cataract surgery, not only static vision of the patients was restored markedly, but also the dynamic vision. DVA could be an important adjunct to the current evaluation system of functional vision, thereby meriting additional attention in clinical assessment.

    This study aims to effectively and robustly suppress the vibration of tension-stabilized structures (TSSs) using a smart dynamic vibration absorber (DVA). In recent years, a strong need has emerged for high-precision and high-functionality space structural systems for realizing advanced space missions. TSSs have attracted attention in this regard as large yet lightweight structural systems with high storage efficiency. A fundamental issue in the application of TSSs is vibration control of strings, of which TSSs are predominantly composed. In particular, the suppression of microvibrations is difficult because the deformation is almost perpendicular to the direction of vibration. A DVA is an effective device for suppressing microvibrations. However, the damping performance is sensitive to changes in dynamic properties. Furthermore, aging degradation and temperature dependence negatively affect DVA performance. This study aimed to develop a smart, active DVA with self-sensing actuation to improve robustness. A small cantilever with a piezoelectric transducer was utilized as a smart DVA. Numerical simulations and experiments showed that a passive DVA and the smart DVA suppressed vibrations but that the smart DVA showed improved effectiveness and robustness.

    Formation of cavernous malformations (CMs) has been recognized to be associated with developmental venous anomaly (DVA) by many authors. Hemodynamic stress due to venous outflow restriction could be hypothesized as a cause. On the other hand, a rare subgroup of DVA with an arterial component has been reported as likely to hemorrhage or be symptomatic. Cases of arterialized DVAs reported previously have not been associated with the presence of CM. We present herein a case report of arterialized DVA in the brainstem with repeated cerebellar hemorrhage. The 49-year-old patient was treated with surgical evacuation of hematoma. A surgical specimen from the hematoma cavity demonstrated CMs on histological examination. To the best of our knowledge, this represents the first report of CM associated with an arterialized DVA. In addition to venous congestion due to outflow obstruction, bleeding from the arterial component of the DVA might be considered as a cause of CM formation.

    Developmental venous anomalies (DVA) are found incidentally but sometimes patients with these anomalies present with varying degrees of neurologic manifestations. We report a patient with early onset complex partial epilepsy and associated DVA and discuss the natural history, neuroimaging and clinical characteristics, and management. A 21-year-old man presented with a history of complex partial epilepsy with secondary generalization which started at the age of 4 years. An electroencephalogram (EEG) was performed which demonstrated spike and wave discharges predominantly in the left frontotemporal region. A magnetic resonance imaging (MRI) was performed which demonstrated a linear flow void suggestive of a DVA. The angiogram demonstrated DVA that connected with the left transverse venous sinus and an anastomotic vein between the straight sinus and the transverse venous sinus traversing the brain parenchyma. He was started on carbamezipine for the treatment of complex partial seizures. Temporal lobe DVA may be associated with complex partial seizures and can be diagnosed by MRI and angiographic findings.

    A developmental venous anomaly (DVA) associated with cerebral cavernous malformation (CCM) is the most common combined vascular malformation. Microsurgical resection of the CCM and avoidance of damage to the adjacent DVA is an overall accepted treatment regimen. Several publications have demonstrated serious consequences that possibly occur after damage of the associated DVA. Conversely, some authors have reported cases of injured DVAs without any relevant postoperative complications. This study compared the clinical and radiologic outcome in patients with and without occlusion of an associated DVA, following microsurgical removal of intracerebral cavernomas. In this single-center evaluation, all consecutive CCM surgical patients from January 1, 2006, to December 31, 2011, were reviewed in a retrospective cohort study. Follow-up was from 12 months to 7 years. The patients were divided into three groups: group I, CCM without associated DVA; group II, damage and occlusion of the associated DVA during CCM removal; and group III, preservation of the associated DVA following CCM removal. Preservation and damage, respectively, of the DVA were defined by evaluation of the corresponding pre- and postoperative magnetic resonance (MR) image sequences. The clinical and radiographic findings in all three groups were evaluated and compared. A total of 38 patients underwent microsurgical resection of a CCM. Overall, 24 patients (63%) had no associated DVA (group I), in 10 patients (26%) the associated DVA was impaired and occluded (group II), and in 4 patients (11%) the associated DVA was surgically not impaired and confirmed as preserved (group III). The rate of postoperative neurologic deficits was 37.5% in group I, 10% in group II, and 75% in group III (p = 0.05). Subgroup analysis in patients with preserved DVA (group III) showed a higher incidence of new postoperative neurologic deficits than in patients with impaired DVA (group II) (p = 0.041). However, no

    Background Domestic violence and abuse (DVA) are associated with increased risk of mental illness, but we know little about the mental health of female DVA survivors seeking support from domestic violence services. Objective Our goal was to characterise the demography and mental health of women who access specialist DVA services in the United Kingdom and to investigate associations between severity of abuse and measures of mental health and health state utility, accounting for important confounders and moderators. Design Baseline data on 260 women enrolled in a randomized controlled trial of a psychological intervention for DVA survivors were analysed. We report the prevalence of and associations between mental health status and severity of abuse at the time of recruitment. We used logistic and normal regression models for binary and continuous outcomes, respectively. The following mental health measures were used: Clinical Outcomes in Routine Evaluation – Outcome Measure (CORE-OM), Patient Health Questionnaire, Generalised Anxiety Disorder Assessment, and the Posttraumatic Diagnostic Scale to measure posttraumatic stress disorder (PTSD). The Composite Abuse Scale (CAS) measured abuse. Results Exposure to DVA was high, with a mean CAS score of 56 (SD 34). The mean CORE-OM score was 18 (SD 8) with 76% above the clinical threshold (95% confidence interval: 70–81%). Depression and anxiety levels were high, with means close to clinical thresholds, and more than three-quarters of respondents recorded PTSD scores above the clinical threshold. Symptoms of mental illness increased stepwise with increasing severity of DVA. Conclusions Women DVA survivors who seek support from DVA services have recently experienced high levels of abuse, depression, anxiety, and especially PTSD. Clinicians need to be aware that patients presenting with mental health conditions or symptoms of depression or anxiety may be experiencing or have experienced DVA. The high psychological

    The objectives of this study are threefold: 1) to examine the effect of frequency of head motion on the clinical dynamic visual acuity (DVA) score in subjects with unilateral vestibular hypofunction (UVH); 2) to compare DVA scores between subjects with UVH and subjects with a complete unilateral vestibular deficit; and 3) to establish whether a relationship exists between the extent of the vestibular deficit and the DVA score. Experimental study. Vestibular outpatient rehabilitation program. A convenience sample of 10 subjects with UVH. Dynamic visual acuity scores were recorded using 2 standard acuity charts: Snellen and E-chart. The DVA scores were obtained at slow (0.5 Hz), moderate (1 and 1.5 Hz), and fast (2.0 Hz) frequencies of head motion in the horizontal and the vertical planes. Percentage of caloric weakness was compared with DVA scores in each subject to test whether a relationship exists between the two. As the frequency of head motion increased, the number of UVH subjects with an abnormal DVA score increased. Subjects with an abnormal DVA score at 1 Hz had the same or higher score as the frequency of the head motion was increased. Spearman correlation analyses revealed low-correlation coefficients between percentage of vestibular paresis at the caloric test and DVA scores (horizontal direction: r = 0.31, p = 0.38 for Snellen chart and r = -0.33, p = 0.35 for the E-chart; vertical: r = 0.05, p = 0.91 for the Snellen chart and r = -0.28, p = 0.50 for the E-chart). Subjects with UVH manifest impaired DVA. The frequency of head motion has an impact on clinical DVA scores in UVH subjects.

    Domestic Violence and Abuse (DVA) is associated with a range of psychosocial and mental health problems. Having a psychiatric illness increases likelihood of being a victim of DVA. Despite the evidence of a high risk for DVA and the serious effects of violent victimization in psychiatric patients, detection rates are low and responses are inadequate. The aim of the BRAVE (Better Reduction trough Assessment of Violence and Evaluation) study is to improve detection of and response to DVA in psychiatric patients. In this article, we present the protocol of the BRAVE study which follows the SPIRIT guidelines. The BRAVE study is a cluster randomized controlled trial. We will include 24 community mental health teams from Rotterdam and The Hague. Twelve teams will provide care as usual and 12 teams will receive the intervention. The intervention consists of 1) a knowledge and skills training for mental health professionals about DVA, 2) a knowledge and skills training of DVA professionals about mental illness, 3) provision and implementation of a referral pathway between community mental health and DVA services. The follow up period is 12 months. Our primary outcome is the rate of detected cases of recent or any history of DVA in patients per team in 12 months. Detection rates are obtained through a systematic search in electronic patient files. Our secondary aims are to obtain information about the gain and sustainability of knowledge on DVA in mental health professionals, and to obtain insight into the feasibility, sustainability and acceptability of the intervention. Data on our secondary aims will be obtained through structured in depth interviews and a questionnaire on knowledge and attitudes on DVA. This study is the first cluster randomized controlled trial to target both male and female psychiatric patients that experience DVA, using an intervention that involves training of professionals. We expect the rate of detected cases of DVA to increase in the

    Zhang, Hui; Shi, Yang; Saadat Mehr, Aryan

    2011-02-01

    In this paper, the design problem for non-fragile dynamic vibration absorbers (DVAs) is investigated. Due to the imprecision of the manufacturing process or the variation during the operation, uncertainty in the parameters of the DVA is unavoidable. The uncertainty may degrade the performance of the designed DVA or even deteriorate the system. Hence, it is practically demanding to propose a design method for a non-fragile DVA, i.e., when the parameters of the DVA vary in an admissible range, an expected vibration suppression level should be guaranteed. The uncertainty of the DVA is feasibly assumed to be norm-bounded. Then, the design problem for the DVA is converted into a static output feedback (SOF) control problem. Sufficient condition for the existence of the non-fragile DVA with a prescribed H∞ level is derived by using a bilinear matrix inequality (BMI). An iterative linear matrix inequality (ILMI) method is employed to solve the BMI condition. Finally, a design example is given to show the effectiveness of the proposed approach.

    Advances in dialysis vascular access (DVA) management have changed where beneficiaries receive this care. The effectiveness, safety, quality, and economy of different care settings have been questioned. This study compares patient outcomes of receiving DVA services in the freestanding office-based center (FOC) to those of the hospital outpatient department (HOPD). It also examines whether outcomes differ for a centrally managed system of FOCs (CMFOC) compared to all other FOCs (AOFOC). Retrospective cohort study of clinically and demographically similar patients within Medicare claims available through United States Renal Data System (USRDS) (2010-2013) who received at least 80% of DVA services in an FOC (n = 80,831) or HOPD (n = 133,965). Separately, FOC population is divided into CMFOC (n = 20,802) and AOFOC (n = 80,267). Propensity matching was used to control for clinical, demographic, and functional characteristics across populations. FOC patients experienced significantly better outcomes, including lower annual mortality (14.6% vs. 17.2%, pDVA-related infections (0.16 vs. 0.20, pDVA services) ($1486 vs. $1533, pDVA services can impact patient clinical and economic outcomes. This research confirmed that patients who received DVA care in the FOC had better outcomes than those treated in the HOPD. The organizational culture and clinical oversight of the CMFOC may result in more favorable outcomes than receiving care in AOFOC.

    Persistent diarrhea is commonly observed after solid organ transplantation (SOT). A few cases of mycophenolate mofetil (MMF)-induced duodenal villous atrophy (DVA) have been previously reported in kidney-transplant patients with chronic diarrhea. Herein, we report on the incidence and characteristics of DVA in SOT patients with chronic diarrhea. One hundred thirty-two SOT patients with chronic diarrhea underwent an oesophago-gastroduodenoscopy (OGD) and a duodenal biopsy after classical causes of diarrhea have been ruled out. DVA was diagnosed in 21 patients (15.9%). It was attributed to mycophenolic acid (MPA) therapy in 18 patients (85.7%) (MMF [n = 14] and enteric-coated mycophenolate sodium [n = 4]). MPA withdrawal or dose reduction resulted in diarrhea cessation. The incidence of DVA was significantly higher in patients with chronic diarrhea receiving MPA compared to those who did not (24.6% vs. 5.1%, p = 0.003). DVA was attributed to a Giardia lamblia parasitic infection in two patients (9.5%) and the remaining case was attributed to azathioprine. In these three patients, diarrhea ceased after metronidazole therapy or azathioprine dose reduction. In conclusion, DVA is a frequent cause of chronic diarrhea in SOT recipients. MPA therapy is the most frequent cause of DVA. An OGD should be proposed to all transplant recipients who present with persistent diarrhea. ©2011 The Authors Journal compilation©2011 The American Society of Transplantation and the American Society of Transplant Surgeons.

  19. H-infinity optimization of a variant design of the dynamic vibration absorber—Revisited and new results

    Cheung, Y. L.; Wong, W. O.

    2011-08-01

    The H∞ optimum parameters of a dynamic vibration absorber (DVA) with ground-support are derived to minimize the resonant vibration amplitude of a single degree-of-freedom (sdof) system under harmonic force excitation. The optimum parameters which are derived based on the classical fixed-points theory and reported in literature for this non-traditional DVA are shown to be not leading to the minimum resonant vibration amplitude of the controlled mass. A new procedure is proposed for the H∞ optimization of such a dynamic vibration absorber. A new set of optimum tuning frequency and damping of the absorber is derived, thereby resulting in lower maximum amplitude responses than those reported in the literature. The proposed optimized variant DVA is also compared to a ground-hooked damper of the same damping capacity of the damper in the DVA. It is proved that the proposed optimized DVA has better suppression of the resonant vibration amplitude of the controlled system than both the traditional DVA and also the ground-hooked damper if the proposed design procedure of the variant DVA is followed.

    Mechanisms that lead to de novo formations of nonfamilial-type cavernomas are not well understood. One of the interesting hypotheses is the causative relationship between developmental venous anomaly (DVA) and cavernoma formation. We report a unique case in which serial imaging demonstrated the evolution of de novo formation of a cavernoma in association with a thrombosed DVA. A detailed review of the causal hypothesis between a DVA and cavernoma is also provided. We report a 37-year-old female patient in whom a cavernoma-like lesion arose 1 year after the progressive thrombosis of a medullary (or caput medusa) vein of a DVA. The presence of an acute angulation in the draining vein may have prompted an intrinsic outflow restriction. Possible worsening of venous disequilibrium led to subsequent thrombus progression, venous congestion, and occlusion of the vein with venous dilation and signs of stasis on follow-up magnetic resonance imaging. Finally, this developed into a lobulated lesion with salt-and-pepper appearance at the converging region of medullary tributaries, which typified the classic features of a cavernoma. Compared with other published cases of de novo cavernoma formation in relation to a DVA, our case, for the first time, allows us to witness the temporal evolution from a thrombosed DVA to the birth of a cavernoma around it. This supports the hypothesis that the cavernoma can be an acquired disease that arises from a DVA.

    The coexistence of cavernous malformations (CMs) and developmental venous anomalies (DVAs) in the cerebellopontine angle (CPA) is exceedingly rare. To the authors' knowledge, only one case of CPA CM with concurrence of a neighboring DVA has been reported to date. The authors presented such vascular malformations in a 36-year-old man with progressive CPA syndrome during the course of six weeks. Preoperative neuroimaging suggested the diagnosis of an extra-axial hemorrhagic lesion in the CPA cistern with a cerebellar DVA in the close vicinity. The lesion was totally removed with the DVA untouched and was confirmed to be extra-axial in intimate contact with only the VII-VIII complex and the draining veins of DVA. Pathology revealed a CM. The patient underwent partial improvement in neurological function postoperatively. The radiographic follow-up at one year revealed no recurrence. CMs should be considered in the differential diagnosis of any extra-axial hemorrhagic mass, especially with a DVA in the proximity. The coexistence of CM and DVA in CPA, although maybe just a coincidence, suggests the possibility of a new subtype of extra-axial CPA CM secondary to a preexisting DVA. A long-term follow-up is justified in discovering the potential mechanism and biology of such uncommon vascular malformations. Copyright © 2012 Elsevier Inc. All rights reserved.

    Dynamic visual acuity (DVA) is the ability to resolve fine spatial detail in dynamic objects during head fixation, or in static objects during head or body rotation. This ability is important for many activities such as ball sports, and a close relation has been shown between DVA and sports expertise. DVA tasks involve eye movements, yet, it is unclear which aspects of eye movements contribute to successful performance. Here we examined the relation between DVA and the kinematics of smooth pursuit and saccadic eye movements in a cohort of 23 varsity baseball players. In a computerized dynamic-object DVA test, observers reported the location of the gap in a small Landolt-C ring moving at various speeds while eye movements were recorded. Smooth pursuit kinematics—eye latency, acceleration, velocity gain, position error—and the direction and amplitude of saccadic eye movements were linked to perceptual performance. Results reveal that distinct eye movement patterns—minimizing eye position error, tracking smoothly, and inhibiting reverse saccades—were related to dynamic visual acuity. The close link between eye movement quality and DVA performance has important implications for the development of perceptual training programs to improve DVA. PMID:28187157

  3. Origins of superior dynamic visual acuity in baseball players: superior eye movements or superior image processing.

    Full Text Available Dynamic visual acuity (DVA is defined as the ability to discriminate the fine parts of a moving object. DVA is generally better in athletes than in non-athletes, and the better DVA of athletes has been attributed to a better ability to track moving objects. In the present study, we hypothesized that the better DVA of athletes is partly derived from better perception of moving images on the retina through some kind of perceptual learning. To test this hypothesis, we quantitatively measured DVA in baseball players and non-athletes using moving Landolt rings in two conditions. In the first experiment, the participants were allowed to move their eyes (free-eye-movement conditions, whereas in the second they were required to fixate on a fixation target (fixation conditions. The athletes displayed significantly better DVA than the non-athletes in the free-eye-movement conditions. However, there was no significant difference between the groups in the fixation conditions. These results suggest that the better DVA of athletes is primarily due to an improved ability to track moving targets with their eyes, rather than to improved perception of moving images on the retina.

    The objective was to determine risk factors associated with difficult venous access (DVA) in the emergency department (ED). This was a prospective, observational study conducted in the ED of an urban tertiary care hospital. Adult patients undergoing intravenous (IV) placement were consecutively enrolled during periods of block enrollment. The primary outcome was DVA, defined as 3 or more IV attempts or use of a method of rescue vascular access to establish IV access. Univariate and multivariate analyses for factors predicting DVA were performed using logistic regression. A total of 743 patients were enrolled, of which 88 (11.8%) met the criteria for DVA. In the adjusted analysis, only 3 medical conditions were significantly associated with DVA: diabetes (odds ratio [OR] 1.72, 95% confidence interval [CI] 1.1-2.8), sickle cell disease (OR 3.8, 95% CI 1.5-9.5), and history of IV drug abuse (OR 2.5, 95% CI 1.1-5.7). Notably, age, body mass index, and dialysis were not. Of patients who reported a history of requiring multiple IV attempts in the past for IV access, 14% met criteria for DVA on this visit (OR 7.7 95% CI 3-18). Of the patients who reported a history of IV insertion into the external jugular, ultrasound-guided IV placement, or a central venous catheter for IV access, 26% had DVA on this visit (OR 16.7, 95% CI 6.8-41). Nearly 1 of every 9 to 10 adults in an urban ED had DVA. Diabetes, IV drug abuse, and sickle cell disease were found to be significantly associated with DVA. Copyright © 2014 Elsevier Inc.

    Domestic violence and abuse (DVA) is a leading contributor to the physical and mental ill health of women. Recent international guidance recommends that undergraduate medical curricula should include DVA. We do not know what is currently taught about DVA to medical students in the UK. Recent international guidance recommends that undergraduate medical curricula should include DVA METHOD: Teaching leads from all UK medical schools (n = 34) were invited to participate in an 18-item online survey about what DVA education is provided, their views of this provision and any feedback provided by students. Descriptive statistics were used to analyse the data. A total of 25 out of 34 medical schools participated in the survey (74%). All respondents felt that there should be formal teaching on DVA in the medical curriculum. Eighty-four per cent of respondents reported that there was some formal teaching in their medical school, and 90% of these reported that it was mandatory. Of those who delivered some teaching, 52% reported that the provision was 0-2 hours in total. Most commonly content was delivered in year 4. DVA teaching was delivered in different modules, by different methods and delivered by a range of different providers. Seventy-five per cent of respondents reported that they felt the provision at their medical school was inadequate or not enough. Barriers to providing DVA education identified included time constraints, failure to perceive it as a medical problem and the assumption that it will be covered elsewhere. Most medical students in the UK receive a small amount of teaching on DVA towards the end of the curriculum. This is perceived as inadequate. © 2017 John Wiley & Sons Ltd and The Association for the Study of Medical Education.

Che cosa ha in comune la simmetria degli antichi, fondata sulla proporzione e sull’armonia, con la simmetria dei moderni e della scienza contemporanea? Il rapporto tra simmetria e natura apre una prospettiva privilegiata per intendere il concetto di simmetria nelle sue caratteristiche essenziali.

  16. Dynamic visual acuity during transient and sinusoidal yaw rotation in normal and unilaterally vestibulopathic humans.

    Tian, J R; Shubayev, I; Demer, J L

    2001-03-01

    The vestibulo-ocular reflex (VOR) stabilizes gaze to permit clear vision during head movements. It has been supposed that VOR function might be inferred from dynamic visual acuity (DVA), the acuity during imposed head motion. We sought to determine effectiveness of DVA for detection and lateralization of unilateral vestibulopathy, using rigorous psychophysical methods. Seventeen normal and 11 unilaterally vestibulopathic subjects underwent measurement of optically best corrected DVA during head motion. A variable size letter "E" 6 m distant was displayed in oblique random orientations to determine binocular DVA by a computer controlled, forced choice method. Three types of whole-body yaw rotation were delivered by a servo-controlled chair synchronized with optotype presentation. Two types of motion were predictable: (1) steady-state 2.0-Hz rotation at 10-130 degrees/s peak velocity with repetitive optotype presentation only during head velocity exceeding 80% of peak; and (2) directionally predictable transients at peak accelerations of 1000, 1600 and 2800 degrees/s2 with optotype presentation for 300 ms. For neither of these predictable motions did DVA in vestibulopathic subjects significantly differ from normal, with suggestions from search coil recordings that this was due to predictive slow and saccadic eye movements. Unilaterally vestibulopathic subjects experienced a significant decrease in DVA from the static condition during ipsilesional rotation for all three peak head accelerations. Only during directionally unpredictable transients with 75 ms or 300 ms optotype presentation was the sensitivity of DVA in unilaterally vestibulopathic subjects significantly abnormal during ipsilesional rotation. The ipsilesional decrease in DVA with head motion was greater for 75 ms than 300 ms optotype presentation. Search coil recordings confirmed hypometric compensatory eye movements during DVA testing with unpredictable, ipsilesional rotation. Receiver

    Developmental venous anomalies (DVA) are common neuroimaging abnormalities that are traditionally diagnosed by contrast-enhanced T1-weighted images as the gold standard. We aimed to evaluate the sensitivity of SWI in detecting DVA and associated cavernous malformations (CM) and microhemorrhages in children in order to determine if SWI may replace contrast-enhanced MRI sequences. Contrast-enhanced T1-weighted images were used as diagnostic gold standard for DVA. The presence of DVA was qualitatively assessed on axial SWI and T2-weighted images by an experienced pediatric neuroradiologist. In addition, the presence of CM and microhemorrhages was evaluated on SWI and contrast-enhanced T1-weighted images. Fifty-seven children with DVA (34 males, mean age at neuroimaging 11.2 years, range 1 month to 17.9 years) were included in this study. Forty-nine out of 57 DVA were identified on SWI (sensitivity of 86%) and 16 out of 57 DVA were detected on T2-weighted images (sensitivity of 28.1%). General anesthesia-related changes in brain hemodynamics and oxygenation were most likely responsible for the majority of SWI false negative. CM were detected in 12 patients on axial SWI, but only in six on contrast-enhanced T1-weighted images. Associated microhemorrhages could be identified in four patients on both axial SWI and contrast-enhanced T1-weighted images, although more numerous and conspicuous on SWI. SWI can identify DVA and associated cavernous malformations and microhemorrhages with high sensitivity, obviating the need for contrast-enhanced MRI sequences. (orig.)

    To report a retrospective series of 84 cerebral developmental venous anomalies (DVAs), focusing on associated parenchymal abnormalities within the drainage territory of the DVA. DVAs were identified during routine diagnostic radiological work-up based on magnetic resonance imaging (MRI) (60 cases), computed tomography (CT) (62 cases) or both (36 cases). Regional parenchymal modifications within the drainage territory of the DVA, such as cortical or subcortical atrophy, white matter density or signal alterations, dystrophic calcifications, presence of haemorrhage or a cavernous-like vascular malformation (CVM), were noted. A stenosis of the collecting vein of the DVA was also sought for. Brain abnormalities within the drainage territory of a DVA were encountered in 65.4% of the cases. Locoregional brain atrophy occurred in 29.7% of the cases, followed by white matter lesions in 28.3% of MRI investigations and 19.3% of CT investigations, CVMs in 13.3% of MRI investigations and dystrophic calcification in 9.6% of CT investigations. An intracranial haemorrhage possibly related to a DVA occurred in 2.4% cases, and a stenosis on the collecting vein was documented in 13.1% of cases. Parenchymal abnormalities were identified for all DVA sizes. Brain parenchymal abnormalities were associated with DVAs in close to two thirds of the cases evaluated. These abnormalities are thought to occur secondarily, likely during post-natal life, as a result of chronic venous hypertension. Outflow obstruction, progressive thickening of the walls of the DVA and their morphological organization into a venous convergence zone are thought to contribute to the development of venous hypertension in DVA.

    Developmental venous anomaly (DVA) is a common congenital venous malformation characterized by dilated medullary veins in caput medusa configuration and a draining vein. Despite the high incidence of DVAs, they are benign anatomic variations and rarely cause symptoms. Here, we report computed tomography and magnetic resonance imaging findings with perfusion images of acute infarction from underlying DVA in a 63-year-old female patient who presented with acute onset of neurologic symptoms and recovered without any neurologic deficit.

    Recent literature on exposure to domestic violence (DV) highlights the need for increased understanding of the dynamics of domestic violence and abuse (DVA). The current aims were to explore whether two separate dimensions, physical and psychological DVA, were evident in adult children's reports of their exposure to DVA in their family of origin, and whether these dimensions affected psychological well-being and perceived satisfaction with emotional support (hereafter referred to as social support satisfaction). Young adults ( N = 465, aged 17-25, 70% female) reported their experiences of DVA as perpetrated by their parents/caregivers, as well as psychological well-being and social support satisfaction, in an online survey. Using confirmatory factor analysis (CFA), we verified the presence of a two-factor model (physical and psychological DVA). Hierarchical linear regression analysis demonstrated the differing impact of these two factors: Specifically, although exposure to psychological DVA (domestic abuse [DA]) was related to reduced psychological well-being, there was no significant effect of exposure to physical DVA (DV). However, mediation analysis suggested the presence of a suppression effect; there was a magnification of the negative relationship between exposure to psychological DA and social support satisfaction when exposure to physical DV was accounted for. Although findings are preliminary, they provide strong evidence to support theoretical arguments regarding the need for future research to conceptualize exposure to DVA in terms of both physical and psychological dimensions. Our findings also highlight that to improve service response and provide effective interventions, it is essential to include exposure to psychological DA in risk assessments of such young adults.

    This study evaluated morphological features of developmental venous anomalies (DVAs) based on magnetic resonance imaging (MRI) findings. The study also evaluated the factors affecting the visibility of DVAs on MRI. We reviewed contrast-enhanced MRIs of 75 patients with DVA. The images were selected from 1,165 consecutive cranial MRIs. The images were examined for the DVA location, the number of collecting veins, the collecting vein diameter, drainage veins and sinuses, any accompanying parenchymal abnormalities or lesions, and the DVA visibility on MRI. DVAs prevalence was determined as 6.4 %. A total of 88 DVAs were observed. Single DVAs were observed in 65 patients, two were observed in 7 patients and three were observed in 3 patients. The DVA caputs had deep localization most frequently in 54.5 % of patients. A total of 98 collecting veins were identified, with a single vein identified in 80 DVAs. A statistically significant difference (p = 0.000) was found in the diameter of the collecting veins between DVAs that were the visible and nonvisible on noncontrast MRI. Most frequently, a single DVA was observed in the patients. A DVA caput could be located in the deep, subcortical, juxtacortical or deep + subcortical and juxtacortical + subcortical regions. Increasing collecting vein diameter increased visibility on noncontrast MRI, and small DVAs could be overlooked, even with contrast-enhanced MRI series if the images were not examined carefully.

    This study compares efficacy and safety of divalproate extended release (DVA-ER) and amitriptyline (AMT) in migraine. Three hundred migraineurs having >4 attacks monthly were randomized into DVA-ER or AMT. The primary end points were >50% reduction in frequency, ≥1 grade improvement in the severity, and >50% improvement in a visual analogue scale (VAS). Secondary end points were functional disability, rescue medication, and adverse events. The median age was 32 years, and 241 were women. 150 patients each received DVA-ER and AMT. At 3 months, 74.7% in DVA-ER and 62% patients in AMT group improved in headache frequency (P = 0.02) and at 6 months, 65.3% and 54%, respectively (P = 0.90). At 3 months, the VAS score improved by >50% in 80.7% in DVA-ER and 64% in AMT (P = 0.005). At 6 months, there was no significant difference between the two groups in VAS score (69.3% vs 56%; P = 0.47) and other outcome parameters. The composite side effects were also not different between the two groups (68% vs 81%); however, hair fall, menstrual irregularity, polycystic ovary, and weight gain were commoner in DVA-ER group. Divalproate extended release is more effective at 3 months than AMT; however, at 6 months, both are equally effective in migraine prophylaxis. © 2013 John Wiley & Sons A/S.

    Despite the low annual risk of hemorrhage associated with a cavernous malformation (CM) (0.6%-1.1% per year), the risk of rehemorrhage rate and severity of neurologic deficits is significantly higher; therefore, we aimed to evaluate the rupture risk of CMs depending on various factors. We retrospectively analyzed medical records of all patients with CM admitted to our institution between 1999 and April 2016.

    Discrimination between atrioventricular node reentry tachycardia (AVNRT) and orthodromic reciprocating tachycardia (ORT) during an electrophysiological study is sometimes challenging. This study aimed to investigate if the difference in the local VA (ventricle-atrium) interval during ventricular entrainment pacing and during tachycardia (DVA, defined as the shortest local VA interval of coronary sinus [CS] during entrainment minus the shortest local VA interval of CS during tachycardia) was different in patients with AVNRT and patients with ORT.Diagnoses of AVNRT or ORT through a concealed accessory pathway (AP) were made according to conventional electrophysiological criteria and ablation results. Entrainment by right ventricular (RV) pacing was performed in each patient before ablation and patients with successful entrainment were included in the study. The DVA was compared between patients with AVNRT and patients with ORT. The DVA in patients with AVNRT was significantly longer than that in patients with ORT (120 ± 20 versus 5.7 ± 9; P DVA was more than 48 ms. In each patient with ORT using a left free wall accessory pathway (AP), right free wall AP, and septal AP, the DVA was less than 20 ms.DVA was found to be a rapid, useful test in distinguishing patients with AVNRT from those with ORT.

    The goal of the present work is to assess the performances of dynamic vibration absorbers (DVA) in suppressing the vibrations of a simply supported beam subjected to an infinite sequence of regularly spaced concentrated moving loads. In particular, several types of DVA are considered: linear, cubic, higher odd-order monomials and piecewise linear stiffness; linear, cubic and linear-quadratic viscous damping. The purpose is to clarify if nonlinear DVAs show improvements with respect to the classical linear devices. The dynamic scenario is deeply investigated in a wide range of operating conditions, spanning the parameter space of the DVA (damping, stiffness). Nonlinear stiffness can lead to complex dynamics such as quasi-periodic, chaotic and sub-harmonic responses; moreover, acting on the stiffness nonlinearity no improvement is found with respect to the linear DVA. A nonlinear non-symmetric dissipation in the DVA leads to a great reduction of the beam response, the reduction is larger with respect to the linear DVA.

    Background: Trigeminal neuralgia (TN) is mostly caused by vascular compression of the nerve's root entry zone due to an ectatic artery. Rarer causes include compression from tumors, vascular malformations or multiple sclerosis plaques. Developmental venous anomalies (DVAs) are benign, aberrantly appearing venous structures that drain normal cerebral tissue. DVAs are a rare etiology of TN. The management of TN caused by a DVA is controversial as disruption of the DVA can be catastrophic. Methods: We report a case of a young man with severe medically refractory TN related to a brachium pontis DVA who was successfully treated by gamma knife stereotactic radiosurgery (GKSR) to the trigeminal nerve. Results: Within 2 weeks of GKSR, the patient reported experiencing 60% pain relief; 5 years postoperatively, he remains completely pain free with some mild sensory loss in the V2 and V3 areas. Conclusions: GKSR has an established role in the management of TN. This is the first reported case of using GKSR to treat TN caused by a DVA. In the setting of a DVA, GKSR should be an initial consideration for TN therapy after medical failure because of the high surgical risk related to disrupting the DVA. © 2015 S. Karger AG, Basel.

    The purpose of the study was to investigate the test-retest reliability and response stability of the Dynamic Visual Acuity (DVA) and Gaze Stabilization Test (GST) in patients with vestibular disorders. Twenty-nine patients with vestibular disease (16-78 years) participated. Subjects performed the GST and DVA in pitch and yaw planes, twice in one session and once after 7-10 days. The GST output is the maximum head velocity at which the patient was able to identify orientation of the letter E. The DVA output is the change in visual acuity when moving the head compared to static acuity. Subjects indicated their level of dizziness and visual blurring using a visual analog scale. Within- and between-sessions intraclass correlation coefficients ranged between 0-0.5 for the DVA and GST measures, with better correlations for within-session assessments. Response stability (standard error of measurement / mean) of the GST ranged between 21-32% and the DVA ranged between 25-69% with vertical DVA being most influenced by measurement error. Subjects' symptoms did not correlate with performance on either test. The current test protocol needs refinement to enhance reliability and stability in persons with vestibular disorders.

    Developmental venous anomalies (DVAs) are associated with epileptic seizures; however, the role of DVA in the epileptogenesis is still not established. Simultaneous interictal electroencephalogram/functional magnetic resonance imaging (EEG/fMRI) recordings provide supplementary information to electroclinical data about the epileptic generators, and thus aid in the differentiation of clinically equivocal epilepsy syndromes. The main objective of our study was to characterize the epileptic network in a patient with DVA and epilepsy by simultaneous EEG/fMRI recordings. A 17-year-old woman with recently emerging generalized tonic-clonic seizures, and atypical generalized discharges, was investigated using simultaneous EEG/fMRI at the university hospital. Previous high-resolution MRI showed no structural abnormalities, except a DVA in the right frontal operculum. Interictal EEG recordings showed atypical generalized discharges, corresponding to positive focal blood oxygen level dependent (BOLD) correlates in the right frontal operculum, a region drained by the DVA. Additionally, widespread cortical bilateral negative BOLD correlates in the frontal and parietal lobes were delineated, resembling a generalized epileptic network. The EEG/fMRI recordings support a right frontal lobe epilepsy, originating in the vicinity of the DVA, propagating rapidly to both frontal and parietal lobes, as expressed on the scalp EEG by secondary bilateral synchrony. The DVA may be causative of focal epilepsies in cases where no concomitant epileptogenic lesions can be detected. Advanced imaging techniques, such as simultaneous EEG/fMRI, may thus aid in the differentiation of clinically equivocal epilepsy syndromes.

    Developmental venous anomalies (DVA) are considered as variant patterns of cerebral venous drainage. Although generally not rare in the cerebellum, DVA of the brain stem or of the cerebellum with drainage through the brain stem are exceptional findings. Because it is not clear whether DVA may sometimes be of clinical significance, we try to correlate the clinical findings of the patients with the course of the variant vessels. We reviewed the literature and report three additional cases. All patients were examined by MRI and digital subtraction angiography. In particular, we discuss the drainage route as compared with the established patterns of posterior fossa blood drainage, which is directed to the dural sinuses, the petrosal vein or the vein of Galen. In one of our patients suffering from trigeminal neuralgia, the close topical relation of the DVA and the trigeminal nucleus and trigeminal nerve entry zone suggests a causal relationship. In a second case the brain stem symptoms were due to haemorrhage of a concomitant cavernoma. It remains unclear if the occurrence of dysarthria and dysaesthesia in the third patient with brain stem DVA was purely coincidental. The only clinical symptom directly attributable to a DVA with transpontine drainage in our series was trigeminal neuralgia. (orig.). With 3 figs., 1 tab

    Previously, cavernous angiomas(CAs)have been thought to be only congenital in origin. Recently, however, a few cases of de novo CAs have been reported in the literature. We present a case of a de novo CA and discuss the etiology of the newly appeared CA. A 29-year-old man was presented to a local clinic because of hypersomnia. MRI demonstrated a heterogeneous mass peripherally located, which was in contact with a developmental venous anomaly(DVA)at the left thalamus. Six years before the presentation, he visited the same clinic because of faintness, and MRI results indicated no abnormality except for the DVA. Three weeks later, he suddenly experienced difficulty in speech, and the MRI revealed an increase in the size of the mass. Subsequently, he was admitted at our institution, and neurological examination revealed aphasia and right hemiparesis. A left carotid angiogram on venous phase showed a narrowing of the DVA, which was seen as it entered the internal cerebral vein. The diagnosis of a de novo CA was made. The mass was completely resected through the transcallosal transventricular approach to avoid injuring the DVA. The DVA could not be found during surgery. The pathological diagnosis was in line with the findings of CA. Postoperatively, the patient continued having difficulty in speech and was transferred to another institution for speech rehabilitation. Although the association of CA and DVA has been described with increasing frequencies recently, the etiology of de novo CA in the case of this association has been a matter of debate. In the present case, it was speculated that a narrowing of the DVA resulted in increased venous pressure and caused the development of de novo CA.

    To analyze the inter-methods agreement in arteriovenous ratio (AVR) evaluation between spectral-domain optical coherence tomography (SD-OCT) and Dynamic Vessel Analyzer (DVA). Healthy volunteers underwent DVA and SD-OCT examination. AVR was measured by SD-OCT using the four external lines of the optic nerve head-centered 7-line cube and by DVA using an automated AVR estimation. The mean AVR was calculated, twice, separately by two independent readers for each tool. Twenty-two eyes of 11 healthy subjects (five women and six men, mean age 35) were included. AVR analysis by DVA showed high inter-observer agreement between reader 1 and 2, and high intra-observer agreement for both reader 1 and reader 2. With regard to AVR analysis on SD-OCT, we found high inter-observer agreement between reader 1 and 2, and low intra-observer agreement for reader 2 but high intra-observer agreement for reader 1. Overall, the mean AVR measured on SD-OCT turned out to be significantly higher than mean AVR measured through DVA (reader 1, 0.9023 ± 0.06 vs 0.8036 ± 0.08; p DVA and SD-OCT). We found significant difference in the two noninvasive methods for AVR measurement, with a tendency for SD-OCT to overestimate retinal vascular caliber in comparison to DVA. This may be useful for achieving greater accuracy in the evaluation of retinal vessel in ocular as well as systemic diseases.

    Government and professional guidance encourages general practice clinicians to identify and refer children who experience domestic violence and abuse (DVA) but there is scant understanding of how general practice clinicians currently work with DVA in families. The study explored general practice clinicians' practice with children and their parents experiencing DVA and reflected on the findings in the light of current research and policy guidelines. Semi-structured interviews with 54 clinicians (42 GPs and 12 practice nurses/nurse practitioners) were conducted across six sites in England. Data were analysed using current literature and emerging themes. Data presented here concern clinicians' perspectives on engaging with family members when a parent discloses that she is experiencing DVA. When a parent disclosed DVA, clinicians were more likely to consider talking to abusive fathers than talking to children about the abuse. Perspectives varied according to whether consultation opportunities arose, risks, consent and confidentiality. Perceptions of 'patienthood', relationships and competence shaped clinicians' engagement. Perpetrators were seen as competent informers and active service users, with potential for accepting advice and support. Clinicians were more hesitant in talking with children. Where this was considered, children tended to be seen as passive informants, only two GPs described direct and ongoing consultations with children and providing them with access to support. Clinicians appear more inclined to engage directly with abusive fathers than children experiencing DVA. Clinician skills and confidence to talk directly with children experiencing DVA, in child sensitive ways, should be developed through appropriate training. © The Author 2015.

    Domestic violence and abuse (DVA), defined as threatening behavior or abuse by adults who are intimate partners or family members, is a key public health and clinical priority. The prevalence of DVA in the United Kingdom and worldwide is high, and its impact on physical and mental health is detrimental and persistent. There is currently little support within healthcare settings for women experiencing DVA. Psychological problems in particular may be difficult to manage outside specialist services, as conventional forms of therapy such as counseling that do not address the violence may be ineffective or even harmful. The aim of this study is to assess the overall effectiveness and cost-effectiveness of a novel psychological intervention tailored specifically for survivors of DVA and delivered by domestic violence advocates based in third-sector organizations. This study is an open, pragmatic, parallel group, individually randomized controlled trial. Women ages 16 years and older experiencing domestic violence are being enrolled and randomly allocated to receive usual DVA agency advocacy support (control) or usual DVA agency support plus psychological intervention (intervention). Those in the intervention group will receive eight specialist psychological advocacy (SPA) sessions weekly or fortnightly, with two follow-up sessions, 1 month and then 3 months later. This will be in addition to any advocacy support sessions each woman receives. Women in the control group will receive usual DVA agency support but no additional SPA sessions. The aim is to recruit 250 women to reach the target sample size. The primary outcomes are psychological well-being and depression severity at 1 yr from baseline, as measured by the Clinical Outcomes in Routine Evaluation-Outcome Measure (CORE-OM) and the Patient Health Questionnaire (PHQ-9), respectively. Secondary outcome measures include anxiety, posttraumatic stress, severity and frequency of abuse, quality of life and cost

    Developmental venous anomalies (DVA) consist of dilated intramedullary veins that converge into a large collecting vein. The appearance of these anomalies was evaluated on whole-brain computed tomography (CT) digital subtraction angiography (DSA) and CT perfusion (CTP) studies. CT data sets of ten anonymized patients were retrospectively analyzed. Five patients had evidence of DVA and five age- and sex-matched controls were without known neurovascular abnormalities. CT angiograms, CT arterial-venous views, 4-D CT DSA and CTP maps were acquired on a dynamic volume imaging protocol on a 320-detector row CT scanner. Whole-brain CTP parameters were evaluated for cerebral blood flow (CBF), cerebral blood volume (CBV), time to peak (TTP), mean transit time (MTT), and delay. DSA was utilized to visualize DVA anatomy. Radiation dose was recorded from the scanner console. Increased CTP values were present in the DVA relative to the unaffected contralateral hemisphere of 48%, 32%, and 26%; and for the control group with matched hemispheric comparisons of 2%, -10%, and 9% for CBF, CBV, and MTT, respectively. Average effective radiation dose was 4.4 mSv. Whole-brain DSA and CTP imaging can demonstrate a characteristic appearance of altered DVA hemodynamic parameters and capture the anomalies in superior cortices of the cerebrum and the cerebellum. Future research may identify the rare subsets of patients at increased risk of adverse outcomes secondary to the altered hemodynamics to facilitate tailored imaging surveillance and application of appropriate preventive therapeutic measures.

  19. Integration Design and Optimization Control of a Dynamic Vibration Absorber for Electric Wheels with In-Wheel Motor

    2017-12-01

    Full Text Available This paper presents an integration design scheme and an optimization control strategy for electric wheels to suppress the in-wheel vibration and improve vehicle ride comfort. The in-wheel motor is considered as a dynamic vibration absorber (DVA, which is isolated from the unsprung mass by using a spring and a damper. The proposed DVA system is applicable for both the inner-rotor motor and outer-rotor motor. Parameters of the DVA system are optimized for the typical conditions, by using the particle swarm optimization (PSO algorithm, to achieve an acceptable vibration performance. Further, the DVA actuator force is controlled by using the alterable-domain-based fuzzy control method, to adaptively suppress the wheel vibration and reduce the wallop acting on the in-wheel motor (IWM as well. In addition, a suspension actuator force is also controlled, by using the linear quadratic regulator (LQR method, to enhance the suspension performance and meanwhile improve vehicle ride comfort. Simulation results demonstrate that the proposed DVA system effectively suppresses the wheel vibration and simultaneously reduces the wallop acting on the IWM. Also, the alterable-domain-based fuzzy control method performs better than the conventional ones, and the LQR-based suspension exhibits excellent performance in vehicle ride comfort.

    The authors report a case of a developmentally normal child with a congenital complex torcular dural arteriovenous fistula (DAVF) who later, in his teenage years, developed several vermian cavernomas within a large cerebellar developmental venous anomaly (DVA). The patient had initially presented with an abnormally large head circumference but no neurological deficits. He underwent several partial embolization procedures in an attempt to decrease the blood supply of the fistula over the course of 8 years. Nine years following initial presentation, he presented with a fourth ventricular hemorrhage, due to development of a new vermian cavernoma adjacent to a previously known vermian DVA and suffered subsequent mild left-sided hemiataxia from which he later recovered. CT angiographic images demonstrated that the vermian DVA drained into the left transverse sinus, which also drained the torcular arteriovenous fistula. A routine follow-up MRI examination 10 years following initial presentation demonstrated interval development of several large cavernomas in the cerebellum, all within the DVA. The patient had no new symptoms at that time and was neurologically intact. This case report highlights the de novo development of multiple cavernous malformations potentially secondary to DAVF-induced venous congestion in a preexisting DVA.

    Domestic violence and abuse (DVA) and child safeguarding are interlinked problems, impacting on all family members. Documenting in electronic patient records (EPRs) is an important part of managing these families. Current evidence and guidance, however, treats DVA and child safeguarding separately. This does not reflect the complexity clinicians face when documenting both issues in one family. To explore how and why general practice clinicians document DVA in families with children. A qualitative interview study using vignettes with GPs and practice nurses (PNs) in England. Semi-structured telephone interviews with 54 clinicians (42 GPs and 12 PNs) were conducted across six sites in England. Data were analysed thematically using a coding frame incorporating concepts from the literature and emerging themes. Most clinicians recognised DVA and its impact on child safeguarding, but struggled to work out the best way to document it. They described tensions among the different roles of the EPR: a legal document; providing continuity of care; information sharing to improve safety; and a patient-owned record. This led to strategies to hide information, so that it was only available to other clinicians. Managing DVA in families with children is complex and challenging for general practice clinicians. National integrated guidance is urgently needed regarding how clinicians should manage the competing roles of the EPR, while maintaining safety of the whole family, especially in the context of online EPRs and patient access. © British Journal of General Practice 2017.

    A major topic of current research in aging has been to investigate ways to promote healthy aging and neuroplasticity in order to counteract perceptual and cognitive declines. The aim of the present study was to investigate the benefits of intensive, sustained judo and karate martial arts training in young and older athletes and nonathletes of the same age for attenuating age-related dynamic visual acuity (DVA) decline. As a target, we used a moving stimulus similar to a Landolt ring that moved horizontally, vertically, or obliquely across the screen at three possible contrasts and three different speeds. The results indicated that (1) athletes had better DVA than nonathletes; (2) the older adult groups showed a larger oblique effect than the younger groups, regardless of whether or not they practiced a martial art; and (3) age modulated the results of sport under the high-speed condition: The DVA of young karate athletes was superior to that of nonathletes, while both judo and karate older athletes showed better DVA than did sedentary older adults. These findings suggest that in older adults, the practice of a martial art in general, rather than the practice of a particular type of martial art, is the crucial thing. We concluded that the sustained practice of a martial art such as judo or karate attenuates the decline of DVA, suggesting neuroplasticity in the aging human brain.

The issue is seen in the context of modernis synesthesia, which was strongly present in the literary ideology of the modernist discourse, and it is analyzed with the help of the theories of ekphrasis of Murray Krieger. In Darío’s canonical works painting plays an important role, both in the form of literary references, and the so called “transpositions of art”, in its intent to create a total art.

    To test the hypothesis that the prevalence of cerebral cavernous malformation (CCM) associated with developmental venous anomalies (DVAs) increases with age, we studied the age-related prevalence of DVA-associated CCM among patients with DVAs. Patients with DVAs on contrast-enhanced MRI exams performed over a 2-year period were included in this study. A single neuroradiologist reviewed all imaging exams for the presence of CCMs. Baseline demographic data collected included age, gender, presence of CNS neoplasm, history of cranial radiation, and history of seizure. Patients were divided into age groups based on decade of life. Cochran-Armitage trend tests were performed to determine if increasing age was associated with CCM prevalence. A total of 1689 patients with DVAs identified on contrast-enhanced MRI were included. Of these patients, 116 (6.9%) had a cavernous malformation associated with the DVA. There was a significant positive association between age and the prevalence of DVA-associated CCM (P = 0.002). The prevalence of DVA-associated CCM was 0.8% for the 0-10 age group, 1.6% for the 11-20 age group, 7.5% for the 21-30 age group, 9.5% for the 31-40 age group, 6.1% for the 41-50 age group, 6.3% for the 51-60 age group, 7.4% for the 61-70 age group, and 11.6% for the >70 age group (P DVA-associated cavernous malformations among patients with DVAs. These findings suggest that DVA-associated cavernous malformations are acquired lesions.

    Full Text Available PURPOSE: Dynamic visual acuity (DVA is a relatively independent parameter for evaluating the ability to distinguish details of a moving target. The present study has been designed to discuss the extent to which age-related cataract impacts DVA in elderly individuals and to determine whether it could be restored after bilateral phacoemulsification combined with intraocular lens implantation surgery. METHODS: Twenty-six elderly cataract patients scheduled for binocular cataract surgery and 30 elderly volunteers without cataract were enrolled in the study. DVA at 15, 30, 60 and 90 degree per second (dps was assessed, and velocity-dependent visual acuity decreases between consecutive speed levels were calculated. RESULTS: Compared with the control group, the patient group exhibited significantly worse DVA performance at all speed levels (p<0.001, and the decreases in velocity-dependent visual acuity were more serious in the patient group at the intervals of 0-15 dps (p<0.001, 15-30 dps (p = 0.007 and 30-60 dps (p = 0.008. Postoperatively, DVA performance at every speed level in the patient group clearly improved (p<0.001 and recovered to levels compatible to the control group. The decrease in visual acuity with increasing speed was less pronounced than during the preoperative phase (p0-15 dps = 0.001, p15-30 dps<0.001 and p30-60 dps = 0.001 and became similar to that of the control group. The postoperative visual benefit regarding DVA was more pronounced than the improvement in static visual acuity (p15 dps = 0.001 and p<0.001 at 30 dps, 60 dps and 90 dps. CONCLUSIONS: The impact of age-related cataract on DVA was more severe than its effects on static visual acuity. After cataract surgery, not only static vision of the patients was restored markedly, but also the dynamic vision. DVA could be an important adjunct to the current evaluation system of functional vision, thereby meriting additional attention in clinical assessment.

    Sexual health and gynaecological problems are the most consistent and largest physical health differences between abused and non-abused female populations. Sexual health services are well placed to identify and support patients experiencing domestic violence and abuse (DVA). Most sexual health professionals have had minimal DVA training despite English National Institute for Health and Care Excellence recommendations. We sought to determine the feasibility of an evidence-based complex DVA training intervention in female sexual health walk-in services (IRIS ADViSE: Identification and Referral to Improve Safety whilst Assessing Domestic Violence in Sexual Health Environments). An adaptive mixed method pilot study in the female walk-in service of two sexual health clinics. Following implementation and evaluation at site 1, the intervention was refined before implementation at site 2. The intervention comprised electronic prompts, multidisciplinary training sessions, clinic materials and simple referral pathways to IRIS ADViSE advocate-educators (AEs). The pilot lasted 7 weeks at site 1 and 12 weeks at site 2. Feasibility outcomes were to assign a supportive DVA clinical lead, an IRIS ADViSE AE employed by a local DVA service provider, adapt electronic records, develop local referral pathways, assess whether enquiry, identification and referral rates were measurable. Both sites achieved all feasibility outcomes: appointing a supportive DVA clinical lead and IRIS ADViSE AE, establishing links with a local DVA provider, adapting electronic records, developing local referral pathways and rates of enquiry, identification and referral were found to be measurable. Site 1: 10% enquiry rate (n=267), 4% identification rate (n=16) and eight AE referrals. Site 2: 61% enquiry rate (n=1090), a 7% identification rate (n=79) and eight AE referrals. IRIS ADViSE can be successfully developed and implemented in sexual health clinics. It fulfils the unmet need for DVA training. Longer

    Single-segment saphenous vein remains the optimal conduit for infrainguinal revascularization. In its absence, prosthetic conduit may be used. Existing data regarding the significance of anastomotic distal vein adjunct (DVA) usage with prosthetic grafts are based on small series. This is a retrospective cohort analysis derived from the regional Vascular Study Group of New England as well as the Brigham and Women's hospital database. A total of 1018 infrainguinal prosthetic bypass grafts were captured in the dataset from 73 surgeons at 15 participating institutions. Propensity scoring and 3:1 matching was performed to create similar exposure groups for analysis. Outcome measures of interest included: primary patency, freedom from major adverse limb events (MALEs), and amputation free survival at 1 year as a function of vein patch utilization. Time to event data were compared with the log-rank test; multivariable Cox proportional hazard models were used to evaluate the adjusted association between vein cuff usage and the primary end points. DVA was defined as a vein patch, cuff, or boot in any configuration. Of the 1018 bypass operations, 94 (9.2%) had a DVA whereas 924 (90.8%) did not (no DVA). After propensity score matching, 88 DVAs (25%) and 264 no DVAs (75%) were analyzed. On univariate analysis of the matched cohort, the DVA and no DVA groups were similar in terms of mean age (70.0 vs 69.0; P = .55), male sex (58.0% vs 58.3%; P > .99), and preoperative characteristics such as living at home (93.2% vs 94.3%; P = .79) and independent ambulatory status (72.7% vs 75.7%; P = .64). The DVA and no DVA groups had similar rates of major comorbidities such as hypertension chronic obstructive pulmonary disease, diabetes mellitus, coronary artery disease, and dialysis dependence (P > .05 for all). Likewise, they had similar rates of distal origin grafts (13.6% vs 12.5%; P = .85), critical limb ischemia indications (P = .53), and prior arterial bypass (58% vs 47%; P = .08

    After prolonged exposure to a given gravitational environment the transition to another is accompanied by adaptations in the sensorimotor subsystems, including the vestibular system. Variation in the adaptation time course of these subsystems, and the functional redundancies that exist between them make it difficult to accurately assess the functional capacity and physical limitations of astro/cosmonauts using tests on individual subsystems. While isolated tests of subsystem performance may be the only means to address where interventions are required, direct measures of performance may be more suitable for assessing the operational consequences of incomplete adaptation to changes in the gravitational environment. A test of dynamic visual acuity (DVA) is currently being used in the JSC Neurosciences Laboratory as part of a series of measures to assess the efficacy of a countermeasure to mitigate postflight locomotor dysfunction. In the current protocol, subjects visual acuity is determined using Landolt ring optotypes presented sequentially on a computer display. Visual acuity assessments are made both while standing and while walking at 1.8 m/s on a motorized treadmill. The use of a psychophysical threshold detection algorithm reduces the required number of optotype presentations and the results can be presented immediately after the test. The difference between the walking and standing acuity measures provides a metric of the change in the subject s ability to maintain gaze fixation on the visual target while walking. This functional consequence is observable regardless of the underlying subsystem most responsible for the change. Data from 15 cosmo/astronauts have been collected following long-duration (approx. 6 months) stays in space using a visual target viewing distance of 4.0 meters. An investigation of the group mean shows a change in DVA soon after the flight that asymptotes back to baseline approximately one week following their return to earth. The

    To evaluate a novel test for dynamic visual acuity (DVA) that uses an adaptive algorithm for changing the size of Landolt rings presented during active or passive head impulses, and to compare the results with search-coil head impulse testing. Prospective study in healthy individuals and patients with peripheral vestibular deficits. Tertiary academic center. One hundred neuro-otologically healthy individuals (age range, 19-80 years) and 15 patients with bilateral (n = 5) or unilateral (n = 10) peripheral vestibular loss (age range, 27-72 years). Testing of static visual acuity (SVA), DVA during active and passive horizontal head rotations (optotype presentation at head velocities >100 degrees/s and >150 degrees/s), and quantitative horizontal head impulse testing with scleral search coils. Difference between SVA and DVA, that is, visual acuity loss (VA loss), gain of the high-acceleration vestibulo-ocular reflex. Passive head impulses and higher velocities were more effective than active impulses and lower velocities. Using passive head impulses and velocities higher than 150 degrees/s, the DVA test discriminated significantly (P test sensitivity was 100%, specificity was 94%, and accuracy was 95%, with search-coil head impulse testing used as a reference. In healthy individuals, VA loss increased significantly with age (P testing with Landolt rings that are adaptively changed in size enables detection of peripheral vestibular dysfunction in a fast and simple way.

    To better suppress the structural vibration in the micro vibration and harsh environment, a new type of damper, tuned particle damper (TPD), was designed by combining the advantage of classical dynamic vibration absorber (DVA) and particle damper (PD). An equivalent theoretical model was established to describe the dynamic behavior of a cantilever system treated with TPD. By means of a series of sine sweep tests, the dynamic characteristic of TPD under different excitation intensity was explored and the damping performance of TPD was investigated by comparing with classical DVA and PD with the same mass ratio. Experimental results show that with the increasing of excitation intensity TPD shows two different dynamic characteristics successively, i.e., PD-like and DVA-like. TPD shows a wider suppression frequency band than classical DVA and better practicability than PD in the micro vibration environment. Moreover, to characterize the dynamic characteristic of TPD, a simple evaluation of the equivalent dynamic mass and equivalent dynamic damping of the cantilever system treated with TPD was performed by fitting the experimental data to the presented theoretical model. Finally, based on the rheology behaviors of damping particles reported by the previous research results, an approximate phase diagram which shows the motion states of damping particles in TPD was employed to analyze the dynamic characteristic of TPD and several motion states of damping particles in TPD were presented via a high-speed camera.

    Domestic violence and abuse (DVA) is a major clinical challenge and public health issue. Sexual health services are an important potential site of DVA intervention. The Assessing for Domestic Violence in Sexual Health Environments (ADViSE) intervention aimed to improve identification and management of DVA in sexual healthcare settings and is a modified version of the Identification and Referral to Improve Safety (IRIS) general practice programme. Our qualitative evaluation aimed to explore the experiences of staff participating in an IRIS ADViSE pilot. Interviews were conducted with 17 sexual health clinic staff and DVA advocate workers. Interviews were audio recorded, transcribed, anonymised and analysed thematically. Staff prioritised enquiring about DVA and tailored their style of enquiry to the perceived characteristics of patients, current workload and individual clinical judgements. Responding to disclosures of abuse was divided between perceived low-risk cases (with quick onwards referral) and high-risk cases (requiring deployment of institution safeguarding procedures), which were viewed as time consuming and could create tensions with patients. Ongoing training and feedback, commissioner recognition, adequate service-level agreements and reimbursements are required to ensure sustainability and wider implementation of IRIS ADViSE. Challenges of delivering and sustaining IRIS ADViSE included the varied styles of enquiry, as well as tensions and additional time pressure arising from disclosure of abuse. These can be overcome by modifying initial training, providing regular updates and stronger recognition (and resources) at policy and commissioning levels. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

    To compare therapy-induced reading and distance visual acuity (dVA) increases in neovascular age-related macular degeneration (nAMD) and uveitis-associated cystoid macular edema. This longitudinal study included 68 treatment-naive eyes: 39 subfoveal nAMD eyes with disrupted photoreceptor layers treated with monthly ranibizumab and 29 uveitis-associated cystoid macular edema eyes with intact photoreceptor layer treated with 1 triamcinolone injection. Patients were examined with high-definition optical coherence tomography, Early Treatment Diabetic Retinopathy Study dVA (logarithm of the minimum angle of resolution), reading acuity (logRADscore), and maximum reading speed (words per minute) over 3 months of therapy. In uveitis-associated cystoid macular edema, logarithm of the minimum angle of resolution and logRADscore improved 1 day post treatment, from 0.49 ± 0.28 to 0.39 ± 0.3 (P = 0.018) and 0.71 ± 0.53 to 0.56 ± 0.49 (P = 0.012), respectively. In nAMD, logarithm of the minimum angle of resolution improved 1 week after anti-vascular endothelial growth factor therapy from 0.59 ± 0.29 to 0.49 ± 0.24 (P = 0.002), with no change in logRADscore. One month after treatment, logRADscore improved from 1.09 ± 0.65 to 0.90 ± 0.60 (P = 0.002). In uveitis-associated cystoid macular edema, the recovery course of reading and dVA was comparable, and in nAMD, reading acuity recovery was delayed. Irrespective of disease, a small reduction in dVA resulted in a larger reading acuity decrease. Cystoid macular edema resolution was associated with rapid synchronous reading and dVA improvement, whereas nAMD was followed by faster recovery of distance than reading acuity. In both conditions, reading acuity expressed by critical angular resolution was more suppressed by active disease and recovered relatively more than distance acuity. These discrepancies indicate that reading acuity might be a more sensitive measure for vision decrease in macular diseases than dVA. Reading

Secondly, the sizing optimization of the dynamic vibration absorber is proceeded to search an optimal damping effect based on the optimal parameters (g, m, z, f. And such the damping effect is simulated in a flat structure, and the results show that the working frequency band and damping effect of the DVA after optimization won 20 % of the effect of ascension compared with that before optimization.

    Vascular malformations are the cause of nearly all non-traumatic intracranial hemorrhage in children beyond the neonatal stage. Therefore, any child presenting with spontaneous intracranial hemorrhage should be evaluated for child abuse and for vascular malformations. Intracerebral malformations of the cerebral vasculature include vein of Galen malformations, arteriovenous malformation (AVM), cavernomas, dural arteriovenous fistulas, venous anomalies (DVA), and capillary teleangiectasies. Although a few familial vascular malformation have been reported, the majority are sporadic. Clinical symptoms, diagnostic and therapeutic options are discussed. (orig.) [German] Vaskulaere Malformationen sind die haeufigste Ursache einer intrakraniellen Blutung im Saeuglings- und Kindesalter. Deswegen sollte jedes Kind mit einer intrakraniellen Blutung auf eine vaskulaere Malformation und Kindesmisshandlung untersucht werden.

    A driving simulator was used to examine the relationship between motion perception and driving performance. Although motion perception test scores have been shown to be related to driving safety, it is not clear which combination of tests are the best predictors and whether motion perception training can improve driving performance. In experiment 1, 60 younger drivers (22.4 ± 2.5 years) completed three motion perception tests (2-dimensional [2D] motion-defined letter [MDL] identification, 3D motion in depth sensitivity [MID], and dynamic visual acuity [DVA]) followed by two driving tests (emergency braking [EB] and hazard perception [HP]). In experiment 2, 20 drivers (21.6 ± 2.1 years) completed 6 weeks of motion perception training (using the MDL, MID, and DVA tests), while 20 control drivers (22.0 ± 2.7 years) completed an online driving safety course. The EB performance was measured before and after training. In experiment 1, MDL (r = 0.34) and MID (r = 0.46) significantly correlated with EB score. The change in DVA score as a function of target speed (i.e., "velocity susceptibility") was correlated most strongly with HP score (r = -0.61). In experiment 2, the motion perception training group had a significant decrease in brake reaction time on the EB test from pre- to posttreatment, while there was no significant change for the control group: t(38) = 2.24, P = 0.03. Tests of 3D motion perception are the best predictor of EB, while DVA velocity susceptibility is the best predictor of hazard perception. Motion perception training appears to result in faster braking responses.

    Full Text Available OBJETIVO: Investigou-se a associação entre deficiência de vitamina A (DVA e condições sociodemográficas em 291 puérperas de diferentes estratos socioeconômicos e seus respectivos recém-nascidos (RN, atendidos em uma maternidade pública do município do Rio de Janeiro, Brasil. MÉTODOS: Os níveis séricos de retinol materno e no sangue de cordão umbilical foram determinados segundo o método Bessey et al. modificado. RESULTADOS: As prevalências de DVA (retinol sérico BACKGROUND: Retinol was determined spectrophotometrically in the blood of 291 mothers at delivery and in the umbilical cord of the newborn. The mothers came from different socioeconomic strata in Rio de Janeiro. METHODS: Levels of retinol were determined using spectrophotometry (Bessey et al. RESULTS: The circulation levels of retinol were low (below 1.05 µmol/L in 22.0% of the mothers and in 54.2% of the newborn. A close association was found between low levels in the mothers' serum and those in the children's' umbilical cord (p <0.0001. There was no association between maternal vitamin A deficiency (DVA and socioeconomic stratum, family income or level of education. CONCLUSIONS: DVA is a distressing health problem among mothers and newborns and its diagnosis must be included in antenatal care. This reinforces the concept that intervention programs must emphasize changes in feeding practices and focus on the most vulnerable groups, of which pregnant women warrant special attention, regardless of socioeconomic stratum.

    This paper considers two systems based on a magnetorheological elastomer (MRE): a MRE isolator under a frequency varying harmonic excitation and a MRE Dynamic Vibration Absorber (DVA) mounted on a frequency-varying structure under a random excitation. It is shown that the commandability of the elastomer improves the isolation performances in the first case, and decreases the stress level in the structure in the second case.

  1. Single-particle measurements of bouncing particles and in situ collection efficiency from an airborne aerosol mass spectrometer (AMS) with light-scattering detection

    A light-scattering module was coupled to an airborne, compact time-of-flight aerosol mass spectrometer (LS-AMS) to investigate collection efficiency (CE) while obtaining nonrefractory aerosol chemical composition measurements during the Southeast Nexus (SENEX) campaign. In this instrument, particles scatter light from an internal laser beam and trigger saving individual particle mass spectra. Nearly all of the single-particle data with mass spectra that were triggered by scattered light signals were from particles larger than ˜ 280 nm in vacuum aerodynamic diameter. Over 33 000 particles are characterized as either prompt (27 %), delayed (15 %), or null (58 %), according to the time and intensity of their total mass spectral signals. The particle mass from single-particle spectra is proportional to that derived from the light-scattering diameter (dva-LS) but not to that from the particle time-of-flight (PToF) diameter (dva-MS) from the time of the maximum mass spectral signal. The total mass spectral signal from delayed particles was about 80 % of that from prompt ones for the same dva-LS. Both field and laboratory data indicate that the relative intensities of various ions in the prompt spectra show more fragmentation compared to the delayed spectra. The particles with a delayed mass spectral signal likely bounced off the vaporizer and vaporized later on another surface within the confines of the ionization source. Because delayed particles are detected by the mass spectrometer later than expected from their dva-LS size, they can affect the interpretation of particle size (PToF) mass distributions, especially at larger sizes. The CE, measured by the average number or mass fractions of particles optically detected that had measurable mass spectra, varied significantly (0.2-0.9) in different air masses. The measured CE agreed well with a previous parameterization when CE > 0.5 for acidic particles but was sometimes lower than the minimum parameterized CE of 0.5.

    Full Text Available Background: The effect of correcting static vision on sports vision is still not clear. Aim: To examine whether sports vision (depth perception [DP], dynamic visual acuity [DVA], eye movement [EM], peripheral vision [PV], and momentary vision [MV], were different among soft tennis adolescent athletes with normal vision (Group A, with refractive error and corrected with (Group B and without eyeglasses (Group C. Setting and Design: A cross-section study was conducted. Soft tennis athletes aged 10–13 who played softball tennis for 2–5 years, and who were without any ocular diseases and without visual training for the past 3 months were recruited. Materials and Methods: DPs were measured in an absolute deviation (mm between a moving rod and fixing rod (approaching at 25 mm/s, receding at 25 mm/s, approaching at 50 mm/s, receding at 50 mm/s using electric DP tester. A smaller deviation represented better DP. DVA, EM, PV, and MV were measured on a scale from 1 (worse to 10 (best using ATHLEVISION software. Statistical Analysis: Chi-square test and Kruskal–Wallis test was used to compare the data among the three study groups. Results: A total of 73 athletes (37 in Group A, 8 in Group B, 28 in Group C were enrolled in this study. All four items of DP showed significant difference among the three study groups (P = 0.0051, 0.0004, 0.0095, 0.0021. PV displayed significant difference among the three study groups (P = 0.0044. There was no significant difference in DVA, EM, and MV among the three study groups. Conclusions: Significant better DP and PV were seen among soft tennis adolescent athletes with normal vision than those with refractive error regardless whether they had eyeglasses corrected. On the other hand, DVA, EM, and MV were similar among the three study groups.

    Hypertension (HT) strongly affects the vascular endothelium, resulting in chronic inflammatory disease. Dynamic vessel analysis (DVA) is a modern methodological approach to analyze vascular function in the retinal microcirculation. The aim of this study was to examine whether a defective retinal vessels response is associated with HT-induced endothelial dysfunction. Retinal vessel reactions to flicker stimulation were examined by DVA in both eyes of 37 hypertensive and 41 healthy control subjects. Plasma concentrations of C-reactive protein (CRP), interleukin-6, and tumor necrosis factor alpha (TNFɑ) were measured using the enzyme-linked immunosorbent assay. Both arterial and vein responses to flicker stimulation were significantly decreased in patients with HT compared with the healthy controls (dilatation of the arteries was lower in the HT group by, on average, 1.31, p = 0.001 and dilatation of the veins was lower in the HT group by, on average, 1.32, p = 0.002) after independent adjustment for age, sex, body mass index, and pressure values. In the hypertensive group, there was a negative correlation between the arterial response to flicker stimulation and the plasma CRP concentration (Spearman's Rank-order Coefficient (Rs) = -0.29, p = 0.07). Similarly, the plasma TNFα concentrations negatively correlated with the arterial response to flicker stimulation (Rs = -0.39, p = 0.02). Our results indicate that DVA directly reflects the actual metabolic status of the retinal endothelium. DVA might be used as an early noninvasive screening tool to detect vascular dysregulation and pan-endothelial dysfunction in patients with HT.

    Vascular malformations are infrequent causes of aqueductal stenoses, developmental venous anomaly (DVA) being the rarest among them. DVAs, also known as venous angiomas, are congenital in origin and characterized by dilatation of vessels in the superficial and deep venous system. Although they are usually clinically silent, they can be complicated by hemorrhage, seizures and neurologic deficits. Herein, we report MR imaging findings of a 7-year-old girl whose hydrocephalus was due to an abnormal vein coursing through the aqueduct. (orig.)

  10. Parametric study on a collocated PZT beam vibration absorber and power harvester

    The parametric effects of a PZT beam that is simultaneously used as a vibration absorber and a power harvester were investigated in this study. A cantilever beam paved with PZT layers and with added tip mass has been widely used as a harvester or sometimes as a Dynamic vibration absorber (DVA). However, the beam is rarely considered a collocated device. In this study, the first step was theoretical derivation of a distributed beam covered with bimorph PZT layers. Then, the beam was attached to a 1DOF vibratory main system. Two indicators for vibration absorption and power harvesting were defined. Numerical results demonstrated that the lumped mass ratio favored both of the abilities, but that the DVA mass ratio influenced these two abilities in exactly the opposite way. The conjunction of a harvester circuit into a DVA shifted its resonance frequency up to 5 % (an extreme case of open circuit R→∞). Simultaneous power harvesting diminished the absorption capability up to 35 % for each set of mass ratios. To achieve the maximum degree of power harvesting, a corresponding load resistance that somewhat increases with the lumped mass ratio is applied. Experimental results verified the existence of the best load resistance, but the measured harvested curve was lower than the theoretical calculation because of structure damping and deviations of PZT material properties.

  11. Parameters Optimization for a Kind of Dynamic Vibration Absorber with Negative Stiffness

    Directory of Open Access Journals (Sweden)

    Yongjun Shen

    2016-01-01

    Full Text Available A new type of dynamic vibration absorber (DVA with negative stiffness is studied in detail. At first, the analytical solution of the system is obtained based on the established differential motion equation. Three fixed points are found in the amplitude-frequency curves of the primary system. The design formulae for the optimum tuning ratio and optimum stiffness ratio of DVA are obtained by adjusting the three fixed points to the same height according to the fixed-point theory. Then, the optimum damping ratio is formulated by minimizing the maximum value of the amplitude-frequency curves according to H∞ optimization principle. According to the characteristics of negative stiffness element, the optimum negative stiffness ratio is also established and it could still keep the system stable. In the end, the comparison between the analytical and the numerical solutions verifies the correctness of the analytical solution. The comparisons with three other traditional DVAs under the harmonic and random excitations show that the presented DVA performs better in vibration absorption. This result could provide theoretical basis for optimum parameters design of similar DVAs.

    Intracranial developmental venous anomalies (DVAs) are considered benign vascular dispositions; they are asymptomatic in the vast majority of cases. They represent extreme variations of the venous drainage and may rarely be responsible for focal venous ischemia leading to neurological dysfunction. The aim of the study is to analyze a group of patients with symptomatic DVAs with capillary stain at angiography. We retrospectively reviewed the clinical and radiological features of patients in which a DVA was considered the cause of a neurological event. In all the patients, the DVA was suspected by angio-CT or MRI and conventional angiography was performed to detail the angioarchitecture of the DVA. A total of 7 patients and 11 DVAs were identified; three patients had multiple DVAs. Three DVAs were frontal, two were parietal, two were thalamic, one was in the midbrain, and three were cerebellar. Patients presented with progressive neurological deficits, seizures, or cerebral hemorrhage. All these DVAs were associated with a peculiar capillary stain at angiography. Although being normal anatomical variations, DVAs may create, because of hemodynamic unbalance, venous ischemia that induces angiogenic phenomena. MRI shows the suffering of the brain and angiography witnesses this angiogenesis under the form of capillary stain. Conventional angiography can thus provide useful information to recognize ''atypical'' symptomatic DVAs. (orig.)

  13. Reducing symbolic-violence in the research encounter: collaborating with a survivor of domestic abuse in a qualitative study in UK primary care.

    2016-03-01

    This paper explores ideas of symbolic violence inherent in the research encounter (Bourdieu 1999). After defining symbolic violence and how the concept enters into domestic violence and abuse (DVA) research, we discuss the challenges arising from a (DVA) survivor taking on the role of interviewer in a qualitative study nested within a UK primary care based trial: IRIS (Identification and Referral to Improve Safety). KS, a survivor of DVA, conducted interviews with 12 women who had been referred to a domestic violence agency by primary care clinicians taking part in the IRIS trial in two UK cities (Bristol and east London) during 2009. Field notes were kept during all of the research meetings with KS and these were included in analysis. Our analysis maps the research pathway of 'non-violent communication' and discusses the role of social symmetry and proximity in the research encounter. We conclude that while a welcoming disposition, empathy and active listening are all generic skills to qualitative research; if a researcher can enter fieldwork with a claim of social proximity and symmetry, their use of these generic skills is enhanced through a process of shared objectification and empowerment talk. We explore the limitations of social proximity, its relationship to feminist and anthropological theories of 'insider' research and its relevance to primary care research. © 2015 Foundation for the Sociology of Health & Illness.

  14. Experimental vibration analysis for a 3D scaled model of a three-floor steel structure

    Directory of Open Access Journals (Sweden)

    Ernesto F. Castillo

    Full Text Available In this paper we present an experimental study of a three dimensional physical model of a three-floor structure subjected to forced vibrations by imposing displacements in its support. The aim of this work is to analyze the behavior of the building when a dynamic vibration absorber (DVA is acting. An analytic simplified analysis and a numerical study are developed to obtain the natural frequencies of the structure. Experiments are carried out in a vibrating table. The frequency range to be experimentally analyzed is determined by the first natural frequency of the structure for which the DVA damping effects are verified. The equipment capabilities, i.e. the frequencies, amplitudes and admissible load, limit the analyses. Nevertheless, satisfactory results are obtained for the study of the first mode of vibration. The effect of different amplitudes of the imposed support motion is also analyzed. In addition, the damping effect of the DVA device is evaluated upon varying its mass and its location in the structure. The characteristic curves in the frequency domain are obtained computing the Fast Fourier Transformation (FFT of the acceleration history registered with piezoelectric accelerometers at different checkpoints for the cases analyzed.

    Seo, Kwang Su

    The objective of this research was to design and synthesize multifunctional poly(ethylene glycol)s (PEG)s using enzyme-catalyzed reactions for multivalent targeted drug delivery. Based on computer simulation for optimum folate binding, a four-arm PEG star topology with Mn = 1000 g/mol was proposed. First, a four-functional core based on tetraethylene glycol (TEG) was designed and synthesized using transesterification and Michael addition reactions in the presence of Candida antarctica lipase B (CALB) as a biocatalyst. The four-functional core (HO)2-TEG-(OH)2 core was successfully prepared by the CALB-catalyzed transesterification of vinyl acrylate (VA) with TEG and then Michael addition of diethanolamine to the resulting TEG diacrylate with/without the use of solvent. The functional PEG arms with fluorescein isothiocyanate (FITC) and folic acid (FA) were prepared using both traditional organic chemistry and enzyme-catalyzed reactions. FITC was reacted with the amine group of H2N-PEG-OH in the presence of triethylamine via nucleophilic addition onto the isothiocyanate group. Then, divinyl adipate (DVA) was transesterified with the FITC-PEG-OH product in the presence of CALB to produce the FITC-PEG vinyl ester that will be attached to the four-functional core via CALC-catalyzed transesterification. For the synthesis of FA-PEG vinyl ester arm, DVA was first reacted with PEG-monobenzyl ether (BzPEG-OH) in bulk in the presence of CALB. The BzPEG vinyl ester was then transesterified with 12-bromo-1-dodecanol in the presence of CALB. Finally, BzPEG-Br was attached to FA exclusively in the gamma position using a new method. The thesis also discusses fundamental studies that were carried out in order to get better understanding of enzyme catalyzed transesterification and Michael addition reactions. First, in an effort to investigate the effects of reagent and enzyme concentrations in transesterification, vinyl methacrylate (VMA) was reacted with 2-(hydroxyethyl) acrylate (2

    Full Text Available Se sabe que la deficiencia de vitamina A (DVA ha existido en América Latina y el Caribe desde mediados de los años sesenta. No obstante, si se exceptúan algunas iniciativas tempranas del Instituto de Nutrición de Centro América y Panamá, había escaso interés en controlarla debido a la detección infrecuente de signos clínicos. En época más reciente, las consecuencias de la DVA para la salud y la supervivencia infantiles ha suscitado gran interés en evaluar el problema y despertado un mayor empeño por controlarlo. La información que estaba disponible a mediados de 1997 sobre la frecuencia de la DVA en países de la Región se revisó minuciosamente. Se aplicaron métodos y puntos de corte aceptados mundialmente para la estimación de la prevalencia a fin de recopilar infomación obtenida de estudios alimentarios, bioqu��micos y clínicos efectuados entre 1985 y 1997 con muestras de 100 personas como mínimo. La DVA en la Región de América Latina y el Caribe es eminentemente subclínica. La prevalencia nacional de la forma subclínica de DVA (retinol sérico < 20 µg/dL en niños menores de 5 años oscila de 6% en Panamá a 36% en El Salvador. El problema es grave en cinco países, moderado en seis y leve en cuatro. No hay datos recientes para Chile, Haití, Paraguay, Uruguay, Venezuela y el Caribe de habla inglesa. En total la población afectada se aproxima a 14,5 millones de niños menores de 5 años (25% de ese grupo de edad. Los escolares y las mujeres en edad adulta también pueden tener una frecuencia elevada de DVA. Las medidas que actualmente están en marcha para controlar la DVA incluyen, entre otras, a la suplementación dirigida a toda la población o a grupos particulares, con elevadas tasas de cobertura logradas durante los días en que se efectúan las inmunizaciones de alcance nacional en algunos países; b la fortificación del azúcar, que ya se ha instaurado en El Salvador, Guatemala y Honduras (se ha

    Full Text Available Vitamin A deficiency (VAD and iron deficiency anemia (IDA have been recognized as public health problems in Honduras for over 30 years. This paper, based on the 1996 National Micro nutrient Survey on 1 678 children 12–71 months of age, presents the results for vitamin A status and anemia prevalence, as well as the level of vitamin A in sugar at the household level. The results showed that 14% of the children were subclinically vitamin A deficient (plasma retinol En Honduras, la deficiencia de vitamina A (DVA y la anemia ferropénica (AF han sido problemas de salud pública reconocidos desde hace más de 30 años. Este trabajo, que se basa en la Encuesta Nacional de Micronutrientes de 1996 aplicada a 1678 niños de 12 a 71 meses de edad, presenta los resultados relacionados con la situación de la vitamina A y la prevalencia de anemia, así como con las concentraciones de vitamina A en el azúcar de consumo domiciliario. Según los resultados, 14% de los niños tenían deficiencia subclínica de vitamina A (retinol plasmático < 20myg/dL y 32% estaban en riesgo de DVA (retinol en plasma 20-30myg/dL. Estos datos indican que en Honduras la DVA es un problema de salud pública de importancia moderada. Un análisis de regresión logística demostró que los niños de 12-23 meses de edad que no vivían en la zona rural del sur del país corrían el mayor riesgo de DVA subclínica. El tener una infección, reflejada en una elevación de las concentraciones de alfa-1-glucoproteína ácida, aumentó más de tres veces el riesgo de DVA subclínica. Los niños de hogares con agua extraída de ríos, arroyos o lagos mostraron un riesgo doble de DVA subclínica, en comparación con otros niños. Ese mismo riesgo doble se encontró en niños de hogares con el baño situado en el exterior. La VDA puede controlarse mediante la fortificación del azúcar. Las concentraciones de retinol en el azúcar de consumo domiciliario fueron de alrededor de 50% de las

    Resolving ambiguous results of D antigen typing is crucial for appropriate and rational administration of anti-D immunoprophylaxis and transfusion practice in obstetric population. The aim of the study was to establish selection criteria of anti-D reagents for our population. A total of 12 689 samples from primiparous women in Split-Dalmatia County, Croatia, were typed for RhD antigen during the period of 5 years. Ambiguous results were submitted to additional serologic investigation and genotyping. RHD genotyping was performed by commercial genotyping kits (Ready Gene weak D ® and Ready gene CDE, Inno-Train, Kronberg, Germany). Relative frequencies and accompanying 95% confidence intervals were used to estimate the prevalence of variants. The prevalence of D variants was 0.42% (95% CI 0.31; 0.53). The most common partial D variant was D Va (RHD*05.05), with the prevalence of 0.08% (95% CI 0.03; 0.13). All weak D variants were weak D types 1, 2 and 3 (RHD*weak D type 1, RHD*weak D type 2, RHD*weak D type 3). Weak D samples were distinguishable from partial D in routine typing due to the difference in reactivity of partial D samples with clones D7B8 and RUM-1. Cell line RUM-1 gives weak or negative reactions with partial DVa category. The most common partial D variant in our population is DVa. It is recommended to use cell lines which do not strongly agglutinate DVa variant in routine RhD typing. The appropriate choice of reagents will enable the serology methods to recognize the cases in which RHD genotyping is required. © 2017 Wiley Periodicals, Inc.

    Highlights: ► Cd tolerance and accumulation are constitutive traits in D. viscosa. ► The physiological mechanisms involved in Cd stress differed between clones. ► The metallicolous clone was more Cd tolerant than the non-metallicolous one. ► Antioxidant enzymes had important roles in each clone, especially peroxidases. -- Abstract: Two clones of Dittrichia viscosa (L.) Greuter from contrasting populations, DV-A (metallicolous) and DV-W (non-metallicolous), were studied to compare Cd accumulation and tolerance. After 10 days of hydroponic culture with 0, 5, 10, and 15 mg Cd L{sup −1}, metal accumulation and plant growth were measured as well as other stress markers such as decrease in the content of photosynthetic pigments, lipid peroxidation, phenols, H{sub 2}O{sub 2}, and free proline. We also analyzed the activity of the antioxidant enzymes guaiacol and ascorbate peroxidases, catalase, superoxide dismutase, and glutathione reductase as well as their isoform patterns. Our results confirmed a high Cd tolerance and accumulation in both clones of D. viscosa, which suggests that these traits are constitutive in this species. However, when the Cd concentration in solution exceeded 10 mg Cd L{sup −1}, DV-A was more tolerant than DV-W. The physiological mechanisms involved in Cd tolerance also differed between them, although phenols and guaiacol peroxidase played an important role in both clones. The effective Cd detoxification of DV-A consisted mainly in a promoted ascorbate peroxidase activity and better efficiency of catalase and glutathione reductase enzymes.

    Full Text Available Dizziness and imbalance are clinically poorly defined terms, which affect ~30% of people over 65 years of age. In these people it is often difficult to define the primary cause of dizziness, as it can stem from cardiovascular, vestibular, psychological and neuromuscular causes. However, identification of the primary cause is vital in determining the most effective treatment strategy for a patient. Our aim was to accurately identify the prevalence of: Benign Paroxysmal Positional Vertigo (BPPV, peripheral, and central vestibular hypofunction in people aged over 50 years who had experienced dizziness within the past year. Seventy six participants aged 51 to 92 (mean ± SD = 69 ± 9.5 years were tested using the Head Thrust Dynamic Visual Acuity (htDVA test, Dizziness Handicap Inventory (DHI, as well as sinusoidal and unidirectional rotational chair testing, in order to obtain data for: htDVA score; DHI score; sinusoidal (whole-body, 0.1 - 2 Hz with peak-velocity at 30deg/s Vestibulo-Ocular Reflex (VOR gain and phase; transient (whole-body, acceleration at 150deg/s/s to a constant velocity rotation of 50deg/s VOR gain and time constant; OptoKinetic Nystagmus (OKN gain and time constant (whole-body, constant velocity rotation at 50deg/s. We found that BPPV, peripheral and central vestibular hypofunction were present in 38% and 1% of participants respectively, suggesting a likely vestibular cause of dizziness in these people. Of those with a likely vestibular cause, 63% had BPPV; a figure higher than previously reported in dizziness clinics of ~25%. Our results indicate that htDVA, sinusoidal (particularly 0.5 - 1 Hz and transient VOR testing were the most effective at detecting people with BPPV or vestibular hypofunction, whereas DHI and OKN were effective at only detecting non-BPPV vestibular hypofunction.

    Full Text Available Getaran banyak terjadi pada mesin-mesin di industri. Salah satu solusi untuk mereduksi getaran berlebih adalah dengan menambahkan Dynamic Vibration Absorber (DVA. Prinsip kerja dari Dynamic Vibration Absorber adalah penambahan massa absorber dan pegas pada sistem utama. DVA akan mereduksi getaran sistem utama dengan menghasilkan getaran yang arahnya berlawanan dengan arah getar dari sistem utama. Berdasarkan penelitian yang dilakukan oleh Pachpute [1], penggunaan DVA telah terbukti dapat mereduksi getaran dari sistem utama yang dioperasikan di frekuensi natural secara signifikan. Dalam penelitian Tugas Akhir ini telah dirancang sebuah mekanisme alat vibration absorber dan energy harvesting metode Cantilever Piezoelectric Vibration Absorber (CPVA. Sistem utama yang digunakan dalam penelitian ini adalah plat datar yang ditopang oleh empat pegas. Plat tersebut akan menerima gaya eksitasi dari pegas dibawahnya yang dihubungkan dengan massa eksentris pada motor DC. Koefisien pegas yang digunakan untuk menumpu plat datar memiliki nilai yang sama, yaitu sebesar 300 N/m. Sehingga eksitasi yang terjadi pada plat datar hanya ke arah translasi. Pada penelitian ini, dilakukan analisa dengan variasi amplitudo massa eksentris sebesar 0.025 m, 0.030 m, dan 0.035 m. Kecepatan putaran motor sebesar 20.61 rad/s (frekuensi natural, 22.05 rad/s (frekuensi panen, dan 25 rad/s (frekuensi lembah. Sedangkan variasi jumlah cantilever piezoelectric yang digunakan adalah 2600, 2800, dan 3000 buah. Dari simulasi yang telah dilakukan, daya bangkitan dan nilai persentase reduksi terbesar dari CPVA terjadi ketika sistem dioperasikan di frekuensi naturalnya, yaitu sebesar 3.52E-7 watt dan 20.36%. Selain itu, dari simulasi juga didapatkan karakteristik CPVA dengan memvariasikan jumlah piezoelectric, didapatkan rentang jumlah piezoelectric optimum adalah 1400 hingga 2400 buah.

    Shape memory alloy (SMA) springs have been used as actuators in many applications although their use in the vibration control area is very recent. Since shape memory alloys differ from conventional alloy materials in many ways, the traditional design approach for springs is not completely suitable for designing SMA springs. Some vibration control concepts utilizing unique characteristics of SMA's will be presented in this paper.A dynamic vibration absorber (DVA) using shape memory alloy (SMA) actuator is developed for attenuation of vibration in a cantilever beam. The design procedure of the DVA is presented. The system consists of a cantilever beam which is considered to generate the real-time vibration using shaker. A SMA spring is used with a mass attached to its end. The stiffness of the SMA spring is dynamically varied in such a way to attenuate the vibration. Both simulation and experimentation are carried out using PID controller. The experiments were carried out by interfacing the experimental setup with a computer using LabVIEW software, Data acquisition and control are implemented using a PCI data acquisition card. Standard PID controllers have been used to control the vibration of the beam. Experimental results are used to demonstrate the effectiveness of the controllers designed and the usefulness of the proposed test platform by exciting the structure at resonance. In experimental setup, an accelerometer is used to measure the vibration which is fed to computer and correspondingly the SMA spring is actuated to change its stiffness to control the vibration. The results obtained illustrate that the developed DVA using SMA actuator is very effective in reducing structural response and have great potential to be an active vibration control medium.

    In this study, the authors used preoperative simulation employing 3D computer graphics (interactive computer graphics) to fuse all imaging data for brainstem cavernous malformations. The authors evaluated whether interactive computer graphics or 2D imaging correlated better with the actual operative field, particularly in identifying a developmental venous anomaly (DVA). The study population consisted of 10 patients scheduled for surgical treatment of brainstem cavernous malformations. Data from preoperative imaging (MRI, CT, and 3D rotational angiography) were automatically fused using a normalized mutual information method, and then reconstructed by a hybrid method combining surface rendering and volume rendering methods. With surface rendering, multimodality and multithreshold techniques for 1 tissue were applied. The completed interactive computer graphics were used for simulation of surgical approaches and assumed surgical fields. Preoperative diagnostic rates for a DVA associated with brainstem cavernous malformation were compared between conventional 2D imaging and interactive computer graphics employing receiver operating characteristic (ROC) analysis. The time required for reconstruction of 3D images was 3-6 hours for interactive computer graphics. Observation in interactive mode required approximately 15 minutes. Detailed anatomical information for operative procedures, from the craniotomy to microsurgical operations, could be visualized and simulated three-dimensionally as 1 computer graphic using interactive computer graphics. Virtual surgical views were consistent with actual operative views. This technique was very useful for examining various surgical approaches. Mean (±SEM) area under the ROC curve for rate of DVA diagnosis was significantly better for interactive computer graphics (1.000±0.000) than for 2D imaging (0.766±0.091; pcomputer graphics than with 2D images. Interactive computer graphics was also useful in helping to plan the surgical

    Robust and reliable covariance estimates play a decisive role in financial and many other applications. An important class of estimators is based on factor models. Here, we show by extensive Monte Carlo simulations that covariance matrices derived from the statistical Factor Analysis model exhibit a systematic error, which is similar to the well-known systematic error of the spectrum of the sample covariance matrix. Moreover, we introduce the Directional Variance Adjustment (DVA) algorithm, which diminishes the systematic error. In a thorough empirical study for the US, European, and Hong Kong stock market we show that our proposed method leads to improved portfolio allocation. PMID:23844016

    This paper presents the new architecture of 2-DOF (degree-of-freedom) drive mode and 1-DOF sense mode gyroscope with the concept of additional anchoring that retains all the advantages of the Dynamic Vibration Absorber (DVA) concept while being operated at high frequencies. These concepts allow reduction of the bandwidth by varying the coupling parameter during the design, thereby increasing the mechanical sensitivity. In the present design, the anchoring concept has been implemented by adding a central anchor for the sense mass. The steady state response and design concept have been devised using analytical modeling.

Staranje se začne z začetkom individualnega življenja s spočetjem. Potek staranja določata dva procesa in sicer: evolucijski, v katerem človek in vsa ostala živa bitja rastejo, se razvijajo in krepijo ter involucijski, ko živi organizem v celoti kvantitativno in kvalitativno peša in propade.

    Exposure of children to domestic violence and abuse (DVA) is a form of child maltreatment with short- and long-term behavioural and mental health impact. Health care professionals are generally uncertain about how to respond to domestic violence and are particularly unclear about best practice with regards to children's exposure and their role in a multiagency response. In this systematic review, we report educational and structural or whole-system interventions that aim to improve professionals' understanding of, and response to, DVA survivors and their children. We searched 22 bibliographic databases and contacted topic experts for studies reporting quantitative outcomes for any type of intervention aiming to improve professional responses to disclosure of DVA with child involvement. We included interventions for physicians, nurses, social workers and teachers. Twenty-one studies met the inclusion criteria: three randomised controlled trials (RCTs), 18 pre-post intervention surveys. There were 18 training and three system-level interventions. Training interventions generally had positive effects on participants' knowledge, attitudes towards DVA and clinical competence. The results from the RCTs were consistent with the before-after surveys. Results from system-level interventions aimed to change organisational practice and inter-organisational collaboration demonstrates the benefit of coordinating system change in child welfare agencies with primary health care and other organisations. Implications for policy and research are discussed. © 2015 The Authors. Child Abuse Review published by John Wiley & Sons Ltd. 'We searched 22 bibliographic databases and contacted topic experts'. We reviewed published evidence on interventions aimed at improving professionals' practice with domestic violence survivors and their children.Training programmes were found to improve participants' knowledge, attitudes and clinical competence up to a year after delivery.Key elements of

    Full Text Available Come strategia per ridurre lo sprawl e la cementificazione della valle del Sarno concentriamo gli interventi in un sistema discontinuo di cluster di residenze attrezzate, sul criterio “low rise – high density”. L’obiettivo è una città verde in estensione, formata da parti di residenze, serre produttive e attrezzature, separate da aree coltivate e parchi. La discontinuità delle nuove parti che si alternano con le aree verdi è finalizzata a contrastare la saturazione edilizia e la saldatura tra centri urbani esistenti. Il fiume Sarno diventa un importante elemento ordinatore del disegno territoriale, incrementando le molteplici relazioni tra gli insediamenti rurali e quelli moderni. / Looking for a strategy avoiding sprawl and soil cementing in the Sarno plain, we compact new buildings in a discontinuous system of multifunction residential clusters with greenhouse, following the criterion “low rise – high density”. The aim is a green extended city, built up by urban parts with residential and productive structures and by utilities separated by rural areas and parks. The discontinuity of new parts alternating with agricultural plots allows that green and unbuilt areas avoid the building saturation of span among the detached cities. The Sarno river should become an element to order the next plans, increasing the multifold relationships among rural and modern settlements.

Data utama digali dari para informan yang dipilih secara purposif, yakni mereka yang secara formal maupun informal memimpin kelompok-kelompok keagamaan Islam seperti Ahmadiyah, Salafi, Jama’ah Tabligh, Syi’ah, dan juga kelompok tradisionalis (Nahdlatul Wathan dan modernis (Muhammadiyah. Hasil kajian menunjukkan bahwa konstruksi sosial mereka muncul lewat tiga momen dialektik yang membentuk realitas subjektif sekaligus objektif tentang the others. Hal itu menentukan cara mereka selaku elit kelompok dalam memaknai dan menyikapi the others. Tipefikasinya menunjukkan, penyikapan mereka tentang the others cenderung eksklusif, dalam batas-batas tertentu inklusif, sementara tendensi pluralistik cenderung absen. Berdasar itu solusi berupa format ideal pengelolaan keragaman bagi penciptaan koeksistensi antarkelompok keagamaan di Kota Mataram diajukan.

    Background To evaluate the incidence, the consequences, and the prevention strategy of anti-D alloimmunizations of D variant carriers in the obstetric population of Split-Dalmatia County, Croatia. Methods RhD immunization events were evaluated retrospectively for the period between 1993 and 2012. Women were tested for RhD antigen and irregular antibodies. Those with anti-D antibody who were not serologically D- were genotyped for RHD. They were evaluated for their obstetric and transfusion history and their titer of anti-D. The neonates were evaluated for RhD status, direct antiglobulin test (DAT), hemoglobin and bilirubin levels, transfusion therapy as well as phototherapy and outcome. Results Out of 104,884 live births 102,982 women were tested for RhD antigen. Anti-D immunization occurred in 184 women which accounts for 0.9% of individuals at risk of anti-D formation. 181 cases occurred in women serologically typed as D-. Three women were partial D carriers (DVa n = 2, DNB n = 1), initially typed RhD+, and recognized as D variant carriers after the immunization occurred. Anti-D titer varied from 1:1 to 1:16. Six children were RhD+, four had positive DAT, and two underwent phototherapy. Conclusion Anti-D immunization occurred in pregnant partial D carriers (DVa, DNB). RhD+ children had serologic markers of hemolytic disease of the fetus and newborn (HDFN), with no cases of severe HDFN. PMID:27994529

    Full Text Available Introduction and objective: To maintain gaze on a stationary target despite rapid cephalic movements we make in our everyday life, it is necessary that the vestibular system detects the velocity of the head and through the vestibular-ocular reflex (VOR induce a movement of the eye of equal magnitude and opposite direction. If this mechanism fails, as happens with the vestibular hypofunction, the patient complains of blurred vision (oscillopsia. One way of checking the operation of this reflex is through quantification of visual acuity during head movements. In this paper, we will describe tests that allow its valuation. Method: Narrative review. Results: There are two types of tools that allow us to measure the dynamic visual acuity (DVA, the clinical tests, and the computerized. Reliability can be increased if in the clinical evaluation we add some system that allows us to control the frequency and the amplitude of the movement which we induce to the head. Discussion: Clinical tests are more simple, accessible and cost-effective, and however, the computerized are more accurate, but require more expensive and less close instruments. Conclusion: Even featuring a variety of objective procedures, the clinical determination of the DVA remains useful for screening the vestibular function and to measure the degree of compensation, during rehabilitation.

  18. Differential voltage analysis as a tool for analyzing inhomogeneous aging: A case study for LiFePO4|Graphite cylindrical cells

    2017-11-01

    In this work the differential voltage analysis (DVA) is evaluated for LiFePO4|Graphite cylindrical cells aged in calendaric and cyclic tests. The homogeneity of the active lithium distribution and the loss of anode active material (LAAM) are measured by the characteristic shape and peaks of the DVA. The results from this analysis exhibit an increasing homogeneity of the lithium-ion distribution during aging for all cells subjected to calendaric aging. At 60 °C, LAAM is found additionally and can be associated with the deposition of dissolved Fe from the cathode on the anode, where it finally leads to the clogging of pores. For cells aged under cyclic conditions, several phenomena are correlated to degradation, such as loss of active lithium and local LAAM for 100% DOD. Moreover, the deactivation of certain parts of anode and cathode due to a lithium-impermeable covering layer on top of the anode is observed for some cells. While the 100% DOD cycling is featured by a continuous LAAM, the LAAM due to deactivation by a covering layer of both electrodes starts suddenly. The homogeneity of the active lithium distribution within the cycled cells is successively reduced with deposited passivation layers and with LAAM that is lost locally at positions with lower external pressure on the electrode.

    The impulse excitation of mechanism causes transient vibration. In order to achieve adaptive transient vibration control, a method which can exactly model the response need to be proposed. This paper presents an analytical model to obtain the response of the primary system attached with dynamic vibration absorber (DVA) under impulse excitation. The impulse excitation which can be divided into single-impulse excitation and multi-impulse excitation is simplified as sinusoidal wave to establish the analytical model. To decouple the differential governing equations, a transform matrix is applied to convert the response from the physical coordinate to model coordinate. Therefore, the analytical response in the physical coordinate can be obtained by inverse transformation. The numerical Runge-Kutta method and experimental tests have demonstrated the effectiveness of the analytical model proposed. The wavelet of the response indicates that the transient vibration consists of components with multiple frequencies, and it shows that the modeling results coincide with the experiments. The optimizing simulations based on genetic algorithm and experimental tests demonstrate that the transient vibration of the primary system can be decreased by changing the stiffness of the DVA. The results presented in this paper are the foundations for us to develop the adaptive transient vibration absorber in the future.

    Full Text Available Background: Venous vascular malformations, also known as venous angiomas or, more exactly, developmental venous anomalies (DVAs, represent congenital, anatomically variant pathways in the normal venous drainage of the brain area. In general neurological practice, DVAs are not considered epileptogenic, therefore, in conducting neuroimaging as a rule, not taken into account. A positive correlation, however, between the location of the DVAs and the electroencephalographic seizure focus is debated. Materials and Methods: The present study provides a complete analysis of clinical and MRI characteristics of symptomatic epilepsies associated with cerebral venous malformations in children and adults. Patients were selected after a retrospective search through the database of the Neurological Center of Epileptology, Neurogenetics and Brain Research of the University Clinic into which, since 2016, patients were prospectively entered. To date (February 2016, there is a total of 5,856 patients with epilepsy of which there are 105 patients with congenital malformations of the brain, and 32 of them were found to have principal diagnosis of DVA. Results: Cavernous angiomas prevailed among venous anomalies (53.1%; DVAs were registered in 46.9% of cases. The associated analysis of DVA localization and the epileptic seizure types showed a direct relationship in 60.0% cases. Conclusion: DVAs as a cause of seizures are important to consider when examining patients with epileptic seizures.

    This study aims to effectively and robustly suppress the low-frequency vibrations of floating slab tracks (FSTs) using dynamic vibration absorbers (DVAs). First, the optimal locations where the DVAs are attached are determined by modal analysis with a finite element model of the FST. Further, by identifying the equivalent mass of the concerned modes, the optimal stiffness and damping coefficient of each DVA are obtained to minimise the resonant vibration amplitudes based on fixed-point theory. Finally, a three-dimensional coupled dynamic model of a metro vehicle and the FST with the DVAs is developed based on the nonlinear Hertzian contact theory and the modified Kalker linear creep theory. The track irregularities are included and generated by means of a time-frequency transformation technique. The effect of the DVAs on the vibration absorption of the FST subjected to the vehicle dynamic loads is evaluated with the help of the insertion loss in one-third octave frequency bands. The sensitivities of the mass ratio of DVAs and the damping ratio of steel-springs under the floating slab are discussed as well, which provided engineers with the DVA's adjustable room for vibration mitigation. The numerical results show that the proposed DVAs could effectively suppress low-frequency vibrations of the FST when tuned correctly and attached properly. The insertion loss due to the attachment of DVAs increases as the mass ratio increases, whereas it decreases with the increase in the damping ratio of steel-springs.

    Superior Canal Dehiscence Syndrome (SCDS) causes auditory and vestibular symptoms. Following surgical repair of the dehiscence, patients often experience dizziness and imbalance. This case report describes a postoperative vestibular exercise program, focusing on the principles of central compensation and habituation, and how it was modified for a patient with delayed progress secondary to strabismus and visual vertigo. A 63-year-old male with history of strabismus eye surgery, right hearing loss, aural fullness, and sensitivity to loud sounds was referred for vestibular rehabilitation (VR). He was seen for one preoperative and six postoperative PT visits over eight months. Outcome measures two weeks postoperative were as follows: Dizziness Handicap Inventory (DHI) 38/100; Timed Up & Go (TUG) 9.92 seconds; Dynamic Gait Index (DGI) 16/24; and a 3-line difference in Dynamic Visual Acuity (DVA). Improved outcomes at discharge included: DHI 18/100; TUG 6.87 seconds; DGI 23/24; and 1-line difference in DVA. He was able to return to work and previously enjoyed recreational activities. Postoperative vestibular rehabilitation programs are functionally and symptomatically beneficial following surgical repair for SCDS. Deviations from expected recovery should be addressed to achieve optimal outcomes as demonstrated in this complicated case report.

    Inducing and manipulating the magnetism in two-dimensional materials play an important role for the development of the next-generation spintronics. In this letter, the effects of the biaxial strain on magnetic properties of vacancy-doped phosphorene are investigated using first-principles calculation. We find although only SV956 doping induces magnetism for unstrained phosphorene, the biaxial strain induces nonzero magnetic moment for SV5566 and DVa doped phosphorene. The biaxial strain also modulates the magnetic state for SV956, SV5566 and DVa doped phosphorene. The local magnetic moment derives from the spin polarization of the dangling bonds near the vacancy. The biaxial strain influences the local bonding configuration near the vacancy which determines the presence of dangling bonds, and then modulates the magnetic state. Our findings promise the synergistic effect of strain engineering and vacancy decoration is an effective method for the operation of phosphorene-based spintronic devices. - Highlights: • Investigation of the magnetic moment of vacancy-doped phosphorene by DFT calculation. • The modulation of the magnetic moment by the biaxial strain. • The analysis of the bonding configuration with the biaxial strain. • The analysis of the electronic structures to explain the evolution of the magnetic moment. • The effects of the biaxial strain on the band gap and doping levels.

    F. communis and D. viscosa are perennial Mediterranean weeds that have been used for different therapeutic purposes in traditional pharmacopeia. Plant extracts were obtained from air dried D. viscosa young shoots (DvA) and F. communis aerial part (FcA) and roots (FcR) with n-hexane. The chemical compositions of the extracts were analyzed by HPLC-DAD, LC-MS (ESI) and LC-Q-TOF techniques. Two sesquiterpene lactones (inuviscolide, tomentosin) and three sesquiterpene acids (costic acid, hydroxycostic acid, ilicic acid) were identified from the D. viscosa extract, while in F. communis extracts three daucane sesquiterpenes (acetoxyferutinin, oxojaeskeanadioyl anisate, fertidin) and one coumarin (ferulenol) derivates were found. Biological activities of plant extracts were studied in in vitro experiments on the colonies and conidia of Botryotinia fuckeliana, Penicillium digitatum, P. expansum, Monilinia laxa, M. fructigena and Aspergillus spp. Extracts showed varying degree of antifungal activities on colony growth and conidia germination. The extract from FcA showed the least effect, while DvA extract had the strongest fungitoxic effects. FcR extract presented a fungitoxic effect on the colony growth, but it was not able to inhibit the conidia germination. These distinctions can be attributed to the differences in chemical composition of plant extracts.

FcR extract presented a fungitoxic effect on the colony growth, but it was not able to inhibit the conidia germination. These distinctions can be attributed to the differences in chemical composition of plant extracts.

    Full Text Available Introdução: A angina de Plaut-Vincent é uma afecção úlcero-necrótica causada pela simbiose de um bacilo fusiforme (Fusobacterium necrophorum e um espirilo (Borrelia vincenti. Ambos são agentes saprófitas habituais da cavidade oral, porém, quando associados, determinam o caráter patogênico da doença. Casuística: Trata-se do caso de uma paciente do sexo feminino, 4 anos de idade, que deu entrada no pronto socorro com choque séptico descompensado não responsivo a volume com necessidade de drogas vasoativas (DVA, além de má conservação dentária, e amigdalas necrosadas. Em 48h evoluiu com piora hemodinâmica refratária a DVA e introdução de hidrocortisona, com crises convulsivas e hemiplegia à esquerda. Foi solicitada TC crânio a qual evidenciou AVC isquêmico. Discussão: Ocorre geralmente em condições de desnutrição e má higiene oral, tendo sua maior incidência entre os adultos-jovens e adolescentes. Cursa com necrose das amigdalas, halitose intensa e disfagia. Conclusão: Considerando que a Angina de Plaut-Vincent acomete principalmente adultos jovens, torna-se de grande relevância relatar o caso de uma paciente pediátrica, que evoluiu de forma incomum, apresentando lesões isquêmicas cerebrovasculares.

    Full Text Available The article deals with the wind-powered drive location and functioning pecularities of agricultural airplane special equipment. The data on the advantages and prospects of the use of the wind-powered drive on agricultural aircraft as well as the experimental and analytical data on discontinuity of the wind stream in the zone of the wind-powered drive installa- and parameters of its operation at aerial spraying on the example of specially equipped An-2 are presented. A mathe- matical model of a wind propeller in discontinuous wind stream is developed. Software package to comprehensively assess wind-powered drive conditions and performance indicators is generated and tested taking into account experimental data, as well as airplane performance and flight modes. The typical data on the wind propeller and the wind-powered drive in the spraying process are received; specific features of the dynamics at the wind-powered drive turning-on and the wind propel- ler rotation at zero load are determined and the data on the wind-propeller blades load imbalance at spraying and transient processes are defined. The author made a quantitative estimation of how the standard change of flight parameters and the operation of the aircraft power plant at spraying influence on the factors of wind-powered drive operation and working liq- uids suppey. The main tendencies, qualitative and quantitative aspects of a wind-powered drive use are defined when per- forming aerial works and the proposals and recommendations for improving and using it in the future are made. The find- ings of the work can be used in the wind-powered drive of agricultural airplane special equipment designing and moderni- zation and drilling of the operational and technological procedures of aerial works performance in agriculture and forestry.

    Full Text Available C. elegans undergoes periods of behavioral quiescence during larval molts (termed lethargus and as adults. Little is known about the circuit mechanisms that establish these quiescent states. Lethargus and adult locomotion quiescence is dramatically reduced in mutants lacking the neuropeptide receptor NPR-1. Here, we show that the aroused locomotion of npr-1 mutants results from the exaggerated activity in multiple classes of sensory neurons, including nociceptive (ASH, touch sensitive (ALM and PLM, and stretch sensing (DVA neurons. These sensory neurons accelerate locomotion via both neuropeptide and glutamate release. The relative contribution of these sensory neurons to arousal differs between larval molts and adults. Our results suggest that a broad network of sensory neurons dictates transitions between aroused and quiescent behavioral states.

    To achieve a much more extensive intake air flow range of the diesel engine, a variable-geometry compressor (VGC) is introduced into a turbocharged diesel engine. However, due to the variable diffuser vane angle (DVA), the prediction for the performance of the VGC becomes more difficult than for a normal compressor. In the present study, a prediction model comprising an elliptical equation and a PLS (partial least-squares) model was proposed to predict the performance of the VGC. The speed lines of the pressure ratio map and the efficiency map were fitted with the elliptical equation, and the coefficients of the elliptical equation were introduced into the PLS model to build the polynomial relationship between the coefficients and the relative speed, the DVA. Further, the maximal order of the polynomial was investigated in detail to reduce the number of sub-coefficients and achieve acceptable fit accuracy simultaneously. The prediction model was validated with sample data and in order to present the superiority of compressor performance prediction, the prediction results of this model were compared with those of the look-up table and back-propagation neural networks (BPNNs). The validation and comparison results show that the prediction accuracy of the new developed model is acceptable, and this model is much more suitable than the look-up table and the BPNN methods under the same condition in VGC performance prediction. Moreover, the new developed prediction model provides a novel and effective prediction solution for the VGC and can be used to improve the accuracy of the thermodynamic model for turbocharged diesel engines in the future.

    2015-06-15

    Purpose: To determine the impact benchmarks and pre-treatment reviews have on improving the quality of submitted clinical trial data. Methods: Benchmarks are used to evaluate a site’s ability to develop a treatment that meets a specific protocol’s treatment guidelines prior to placing their first patient on the protocol. A pre-treatment review is an actual patient placed on the protocol in which the dosimetry and contour volumes are evaluated to be per protocol guidelines prior to allowing the beginning of the treatment. A key component of these QA mechanisms is that sites are provided timely feedback to educate them on how to plan per the protocol and prevent protocol deviations on patients accrued to a protocol. For both benchmarks and pre-treatment reviews a dose volume analysis (DVA) was performed using MIM softwareTM. For pre-treatment reviews a volume contour evaluation was also performed. Results: IROC Houston performed a QA effectiveness analysis of a protocol which required both benchmarks and pre-treatment reviews. In 70 percent of the patient cases submitted, the benchmark played an effective role in assuring that the pre-treatment review of the cases met protocol requirements. The 35 percent of sites failing the benchmark subsequently modified there planning technique to pass the benchmark before being allowed to submit a patient for pre-treatment review. However, in 30 percent of the submitted cases the pre-treatment review failed where the majority (71 percent) failed the DVA. 20 percent of sites submitting patients failed to correct their dose volume discrepancies indicated by the benchmark case. Conclusion: Benchmark cases and pre-treatment reviews can be an effective QA tool to educate sites on protocol guidelines and to minimize deviations. Without the benchmark cases it is possible that 65 percent of the cases undergoing a pre-treatment review would have failed to meet the protocols requirements.Support: U24-CA-180803.

    Full Text Available A Petrobras tem, notadamente, grande participação no Produto Interno Bruto brasileiro, de modo que variações bruscas na riqueza gerada pela estatal podem repercutir na formação do PIB do país. O presente estudo, por meio da metodologia de pesquisa bibliográfica e de estudo de caso, tem como objetivo geral responder ao seguinte questionamento: houve variação do coeficiente de correlação do PIB brasileiro versus o Valor Adicionado da Petrobras em função do reconhecimento das perdas causadas pela corrupção, evidenciadas nas demonstrações de 2014 da companhia? Para encontrar a resposta, realizou-se, no primeiro momento, uma análise da Demonstração do Valor Adicionado (DVA da companhia referente aos exercícios de 2008 a 2013. Em seguida, como ponto de referência, adicionou-se a DVA do exercício de 2014 para uma análise comparada. Por meio do cruzamento de dados e com o apoio de ferramentas estatísticas, concluiu-se que houve expressiva variação do coeficiente de correlação entre o PIB brasileiro e o Valor Adicionado da Petrobras no exercício de 2014, possivelmente em função do reconhecimento das perdas por corrupção e desvalorização de seu ativo.

    Jurassic sedimentary rocks of the Telekesvölgy Complex (Bódva Series), Telekesoldal Complex (Telekesoldal Nappe) and the Csipkés Hill olistostrome in Rudabánya Hills (NE Hungary) were sampled for microfacies studies and interpretation of the depositional environments. The Telekesvölgy Complex is made up of reddish to greenish marl, occasionally containing limestone olistoliths — gradually progresses from the Norian Hallstatt Limestone of the Bódva Series — then grey marl, which may correspond to the latest Triassic Zlambach Formation. This variegated marl progresses into grey marl and calcareous marl, containing crinoid fragments. It may be interpreted as a hemipelagic facies, relatively close to submarine highs. Bajocian to Lower Bathonian black shales, rich in radiolarians and sponge spicules representing typical deep pelagic facies, are also assigned to the Telekesvölgy Complex. The Telekesoldal Complex represents a mélange-like subduction-related complex that consists of black shales, sandstone turbidites and olistostrome beds, and deposited by gravity mass flows. A relatively deep marine basin in the proximity of a submarine slope is likely to be the depositional environment of this unit. The clasts of the olistostromes are predominantly Middle to Upper Triassic pelagic limestones, rhyolite and basalt. Subduction related nappe stacking of the ocean margin during the Middle to Late Jurassic may have created suitable conditions for this sedimentation pattern. Bajocian-Callovian age of the complex was proved by the revision of the radiolarian fauna and new palynological data, the first from the Jurassic of the Aggtelek-Rudabánya Hills. The Csipkés Hill olistostrome consists of carbonate turbidite beds containing Jurassic platform derived foraminiferal and olistostrome horizons with Middle-Upper Triassic limestone clasts of red Hallstatt facies.

Específicamente en el sistema inmune, esta vitamina tiene efectos muy importantes sobre componentes específicos tanto de la respuesta inmune innata como de la adaptativa. En la inmunidad innata, el ácido retinoico (AR participa en la regeneración de las mucosas y epitelios, promueve la diferenciación de células como los neutrófilos y eosinófilos y potencia la fagocitosis. Además, ayuda a la migración de las diferentes células inmunes promoviendo la producción de metaloproteinasas de matriz extracelular. Aunque sus efectos en las células NK son más controversiales, se ha encontrado que el número y la función lítica de estas células disminuyen cuando hay deficiencia de vitamina A (DVA. Por otra parte, el AR influencia el desarrollo de la inmunidad adaptativa alterando el perfil de producción de citoquinas por parte de las células presentadoras de antígeno, lo que influye en la diferenciación de los linfocitos T ayudadores. En general, se ha observado que el AR amplifica la proliferación de las células T y potencia el desarrollo de células plasmáticas a partir de los linfocitos B maduros. Todos estos efectos tienen repercusiones importantes en la adecuada defensa contra las infecciones, especialmente en la infancia en la cual la DVA es un problema importante de salud pública, no solo en Colombia sino también en aproximadamente otros 60 países.

    Chemical composition, size distributions, and degree of oligomerization of secondary organic aerosol (SOA) from α-pinene (C10H16) ozonolysis were investigated for low-temperature conditions (223 K). Two types of experiments were performed using two simulation chambers at the Karlsruhe Institute of Technology: the Aerosol Preparation and Characterization (APC) chamber, and the Aerosol Interaction and Dynamics in the Atmosphere (AIDA) chamber. Experiment type 1 simulated SOA formation at upper tropospheric conditions: SOA was generated in the AIDA chamber directly at 223 K at 61 % relative humidity (RH; experiment termed cold humid, CH) and for comparison at 6 % RH (experiment termed cold dry, CD) conditions. Experiment type 2 simulated SOA uplifting: SOA was formed in the APC chamber at room temperature (296 K) and warm dry, WD) or 21 % RH (experiment termed warm humid, WH) conditions, and then partially transferred to the AIDA chamber kept at 223 K, and 61 % RH (WDtoCH) or 30 % RH (WHtoCH), respectively. Precursor concentrations varied between 0.7 and 2.2 ppm α-pinene, and between 2.3 and 1.8 ppm ozone for type 1 and type 2 experiments, respectively. Among other instrumentation, a chemical ionization mass spectrometer (CIMS) coupled to a filter inlet for gases and aerosols (FIGAERO), deploying I- as reagent ion, was used for SOA chemical composition analysis. For type 1 experiments with lower α-pinene concentrations and cold SOA formation temperature (223 K), smaller particles of 100-300 nm vacuum aerodynamic diameter (dva) and higher mass fractions (> 40 %) of adducts (molecules with more than 10 carbon atoms) of α-pinene oxidation products were observed. For type 2 experiments with higher α-pinene concentrations and warm SOA formation temperature (296 K), larger particles ( ˜ 500 nm dva) with smaller mass fractions of adducts (climate models.

O diagnóstico preciso da demência vascular (Dva é difícil e nossos conhecimentos sobre a organização neuropsicológica do cérebro em estados de doença e a evolução da doença são precários, tornando penosa a avaliação das respostas a diferentes intervenções. MÉTODOS: São discutidos os critérios diagnósticos, os instrumentos de avaliação do curso da Dva e as diferentes intervenções terapêuticas atualmente em estudo. RESULTADOS: O uso de critérios diagnósticos estritos e a otimização dos métodos de avaliação evolutiva são passos importantes para otimizar o tratamento dos pacientes com DVa. A prevenção de novos eventos cerebrovasculares é a única medida comprovadamente eficaz para promover estabilização e talvez regressão das alterações cognitivas e comportamentais nestes pacientes. As evidências de possível benefício de estimulantes inespecíficos do metabolismo cerebral e de drogas neuroprotetoras não são suficientes para indicar seu uso rotineiro. Medidas de estruturação do ambiente, o uso racional e parcimonioso de medicamentos em geral, e a definição através de testes neuropsicológicos de rotas terapêuticas adaptadas às necessidades de cada paciente são também importantes. CONCLUSÕES: Critérios diagnósticos e de acompanhamento evolutivo da DVa são ainda inadequados. A prevenção de novos episódios cerebrovasculares é a base do tratamento dos pacientes com DVa. O uso criterioso de drogas psiquiátricas, uma abordagem neurocognitiva dirigida aos déficits de cada paciente e a estruturação do ambiente para reduzir demandas desnecessárias e cansaço são importantes medidas complementares, mas deixam grande margem para otimização do tratamento.BACKGROUND: Treatment of vascular dementia

În legătură cu domeniul nostru de studiu, paradoxurile concepţiei politice ale lui Rousseau se referă la contradicţia dintre aspiraţiile modernităţii şi criticile violente ale progresului social. El pune accentul pe contradicţia dintre încrede-rea deplină în ,,contractul social”, ca pattern cultural şi lipsa de încredere în ,,educaţia socială”. Unicul mod de a depăşi aceste contradicţii este abordarea noului model al filosofiei educaţiei bazat pe reforme radicale pentru a facilita autodezvoltarea individului.   THE PARADOXES OF POLITICAL CONCEPTION IN THE WORK OF JEAN-JACQUES ROUSSEAUHis ideas have a big impact on the society at the end of the 18th century and the whole 19th century period. These ideas transform his spirit into a modern one, as well as a political ideologist, main voice of the French Revolution and pioneer of the Romantic Movement. Related to our article subject, Rousseau's political conceptual paradoxes refer to the contradiction between moderni-ty aspiration and the violent critic of the social progress. He emphasizes the contradiction between full trust of the "social contract", as a cultural pattern and the distrust of the "social education." The only way to leave the contradictions behind is his new education philosophy pattern based on a radical reform in order for the individual to develop himself.

  2. Aspetti deontologici e giuridici della Responsabilità professionale del chirurgo in Italia. Evoluzione storica a partire dal '900.

    È pleonastico ricordare che ogni individuo raziocinante delle essere responsabile delle sue azioni: deve agire con la coscienza degli scopi che si propone evitando possibili conseguenze negative dei suoi atti. In ambito medico questo tipo di responsabilità è codificata con le norme della "deontologia". Per secoli l'arte terapeutica è stata praticata da individui dotati di una particolare vocazione ed una particolare cultura acquisita da Maestri dell'arte ancor prima che dalla propria esperienza, con nozioni di erboristeria e di elementari conoscenze anatomiche e di fisiologia, circondati da un'aura sacerdotale e da un rispetto derivante dal timore e dall'ammirazione per il coraggio e auspicabilmente dai successi, e facendo riferimento nell'occidente mediterraneo alle regole operative fissate nel Giuramento di Ippocrate, di significato tra il sacro ed il deontologico. Lo sviluppo delle tecniche anestesiologiche a partire dalla seconda metà dell'800 ha determinato l'ampliamento delle iniziative chirurgiche di tipo elettivo, a fianco con gli storici interventi in emergenza per la cura di lesioni traumatiche, ancor prima delle acquisizioni riguardanti le infezioni. Con l'espansione del campo di azione della chirurgia, le possibili complicanze ed i possibili insuccessi hanno fatto da contrappeso ai sentimenti di rispetto e di fiducia nei confronti dei chirurghi, giungendo a far assimilare in tali casi la loro opera quale causa all'origine di danni, provocati rientrando quindi nella categoria dei reati sottoposti alla Legge penale. Così, al termine deontologico di "responsabilità" valido per ogni iniziativa ed ogni professione, per i medici è venuto ad associarsi la qualifica di "professionale", con un significato di presunta colpevolezza. Da una parte le regole deontologiche si sono ampliate, ed hanno coinvolto direttamente il paziente nella fase decisionale delle terapie chirurgiche, formalizzate programmaticamente in moderni codici deontologici ed

    The Veterans Health Administration (VHA) serves the health care needs of an adult, predominantly male, and aging population. The aging profile of VHA patients is 25% greater than the civilian sector (DVA 2001). Aged patients are at higher risk for falls. In February 2002, 6 VHA medical centers profiled their inpatients' fall risk profile as one aspect of program initiatives targeted at reducing veterans' fall risk and fall-related injuries, participating in a one-day collection of fall risk measurement using the Morse Fall Scale (MFS) for all inpatients (n = 1819), acute and long-term care units. Data results are reported for age, MFS score, and the relationship between age and score, and by type of ward/unit, ie, predominately acute and critical care or long-term care. The results of this prevalence study documented that the veteran inpatient population are at high-risk for anticipated physiological falls. This Veteran Integrated Services Network-wide Deployment of an Evidence-based Program to Prevent Patient Falls study was completed as part of a nationally funded clinical initiative, National Program Initiative 20-006-1.

    Matthew D Nelson

    Full Text Available Neuropeptides signal through G-protein coupled receptors (GPCRs to regulate a broad array of animal behaviors and physiological processes. The Caenorhabditis elegans genome encodes approximately 100 predicted neuropeptide receptor GPCRs, but in vivo roles for only a few have been identified. We describe here a role for the GPCR FRPR-4 in the regulation of behavioral quiescence and locomotive posture. FRPR-4 is activated in cell culture by several neuropeptides with an amidated isoleucine-arginine-phenylalanine (IRF motif or an amidated valine-arginine-phenylalanine (VRF motif at their carboxy termini, including those encoded by the gene flp-13. Loss of frpr-4 function results in a minor feeding quiescence defect after heat-induced cellular stress. Overexpression of frpr-4 induces quiescence of locomotion and feeding as well as an exaggerated body bend posture. The exaggerated body bend posture requires the gene flp-13. While frpr-4 is expressed broadly, selective overexpression of frpr-4 in the proprioceptive DVA neurons results in exaggerated body bends that require flp-13 in the ALA neuron. Our results suggest that FLP-13 and other neuropeptides signal through FRPR-4 and other receptors to regulate locomotion posture and behavioral quiescence.

    Full Text Available Based on the Rayleigh beam theory, the forced transverse vibrations of a closed double single-walled carbon nanotube (SWCNT system containing a fluid with a Pasternak layer in-between are investigated. It is assumed that the two single-walled carbon nanotubes of the system are continuously joined by a Pasternak layer and both sides of SWCNTs containing a fluid are closed. The dynamic responses of the system caused by arbitrarily distributed continuous loads are obtained. The effect of compressive axial load on the forced vibrations of the double single-walled carbon nanotube system is discussed for one case of particular excitation loading. The properties of the forced transverse vibrations of the system are found to be significantly dependent on the compressive axial load. The steady-state vibration amplitudes of the SWCNT decrease with increasing of length of SWCNT. Vibrations caused by the harmonic exciting forces are discussed, and conditions of resonance and dynamic vibration absorption are formulated. The SWCNT-type dynamic absorber is a new concept of a dynamic vibration absorber (DVA, which can be applied to suppress excessive vibrations of corresponding SWCNT systems.

    Full Text Available V članku so obravnavani praktični ukrepi za vključevanje rezultatov ocene tveganja zaradi izrednih vremenskih dogodkov v postopek prostorskega načrtovanja. Na primerih ocene tveganja zaradi žleda za prenosno in distribucijsko elektroenergetsko omrežje ter za vetrne elektrarne je predstavljen postopek, ki vnaša rezultate ocene tveganja v analizo ustreznosti prostora. Najprej je izdelana ocena tveganja za prenosno in distribucijsko omrežje zaradi žleda. Rezultati ocene tveganja so uporabljeni kot podlaga za presojo predlaganih različic tras visokonapetostnega daljnovoda in kot vhodni podatek za analizo ustreznosti prostora za umestitev vetrnih elektrarn. Različici za umestitev vetrnih elektrarn z upoštevanjem tveganja in brez tega smo primerjali z gospodarskega vidika in ugotovili, da lahko škode zaradi izrednih vremenskih dogodkov pomembno vplivajo na gospodarsko upravičenost načrta. Ugotavljamo, da lahko rezultate ocene tveganja na dva načina vključimo v načrtovanje elektroenergetske infrastrukture, in sicer s posodobitvijo inženirskih standardov in izogibanjem območjem, na katerih bi lahko nastale največje škode na infrastrukturi zaradi izrednih vremenskih dogodkov. Ocena tveganja je pomembna informacija, ki lahko vpliva na odločitve v zvezi z rabo prostora in tehničnimi ukrepi za povečanje odpornosti infrastrukture.

    Full Text Available The aim of this study was to search for the partial D phenotype in Moroccan blood donors with weak D expression. The study included 32 samples with weak D phenotype, and partial D category red blood cells were detected with the D-Screen Diagast kit, which consists in 9 monoclonal anti-D antibodies specific for the most common categories of partial D. Among the 32 samples studied, we identified 13 specific reactions to a partial D antigen (3 DVI, 2 DVa, 2 DIII(a,b,c, and 6 DVII, with 8 reactions suggesting a weak D and 11 reactions providing no formal argument in favor of a partial D antigen. This work can be used to validate the performance of the anti-D reagent and to improve the safety of transfusion of red blood cells from donors expressing the partial D antigen by integrating the finding into the recipient file with a recommendation concerning the appropriate care.

  16. The effects of drift and displacement motion on Dynamic Visual Acuity

    Directory of Open Access Journals (Sweden)

    2005-01-01

    Full Text Available Dynamic Visual Acuity (DVA can be measured from two types of equivalently considered movement referred to as drifting-motion and displacement-motion. Displacement motion can be best described as the horizontal displacement of a stimulus, thus implying pursuit eye movements, and involves moving the stimulus from the fixation point of gaze towards the periphery. The drifting motion of a Gabor patch, for example, avoids pursuit eye movements, since the gaze is fixed in a point of the patch. Our data shows that in both types of movement visual acuity (VA, expressed in terms of spatial frequency, diminished as the velocity of the target increased. However, the slope of the regression equation indicated that this impairment is more than two-fold in the case of drifting-motion when compared to displacement motion. As the greater impairment took place when pursuit eye movements did not exist, our data suggests that these two types of motions correct differently for retinal slip. Retinal slip appears to be less efficiently compensated for in the case of drifting motion having adverse consequences on VA, while retinal slip has a higher tolerance in the case of displacement motion exhibited by the performance in VA.

Oziroma natančneje, kako naj uporabnikom in urbanitom določimo vlogo v projektih javnih parkov? Naša hipoteza je, da imajo družbene vede v povezavi s krajani dve vlogi – spoznavno vlogo, ki v civilni družbi opisuje rabo in družbeno dinamiko na delovnem mestu, ter vlogo posrednika (mediatorja med prebivalci in projektanti, predstavniki gradbene industrije ter vzdrževalci parkov. Obe vlogi sta med seboj tesno povezani, in sicer zaradi velike pozornosti, posvečene lokacijam. To pa zahteva empirično obravnavo. Ta je v tem članku etnografska. Metodologijo, ki jo v Parizu uporabljajo že več let, preverjamo z različnimi ameriškimi tehnikami. V članku bomo obravnavali dva primera, in sicer parka Parc Floral de Paris in Les Jardins d’Eole. Sociologijo so vsakič uporabili drugače. Modeli, ki so jih družboslovci uporabili pri obravnavanju parkov, kažejo, da bi morali razmisliti o novi »razdelitvi nalog« med različnimi udeleženci projekta, tudi med prebivalci, ki so hkrati uporabniki in državljani.

Neavtorski pristop je po izkušnjah osnova za dobro vodenje projekta, za ustvarjanje pogojev za konstruktivno sodelovanje interdisciplinarne delovne skupine in vseh preostalih sodelujočih pri projektu. Predstavljena sta dva konkretna primera. Posebno zanimiva je njuna primerjava, saj je v prvem primeru projekt zaradi dobrega sodelovanja med naročniki, investitorji in projektanti ter zaradi kooperativne zainteresirane javnosti pridobil kakovost, v drugem pa je (zaradi in tudi na škodo javnosti precej izgubil. Za tolikokrat omenjeno nujnost participacije javnosti v projektih ocenjujemo, da je je pravzaprav dovolj.

Problem je pogosto na drugi strani – kako pred eno javnostjo (npr. sosedje, neposredno prizadeti zavarovati skupni, javni interes.

    Full Text Available Prihodnja osvetlitev na podlagi polprevodniških virov svetlobe bo spremenila nočno podobo mest. Možnosti njihove umestitve in uporabe v urbanem prostoru so številne. V članku zato proučujemo, ali bi njihova prihodnja uporaba v splošni zunanji razsvetljavi pozitivno vplivala na človekovo sprejemanje tako osvetljenega urbanega prostora. Na podlagi inovativne uporabe omenjenih virov svetlobe smo izoblikovali dva različna koncepta osvetlitve. Prvi koncept temelji na ploskovni osvetlitvi, drugi pa na detajlnem prikazu arhitekturno–urbanih elementov. Predlogi za osvetlitev so bili narejeni na petih različnih lokacijah mesta. Poleg izpolnjevanja funkcionalnih potreb upoštevajo tudi urbanistični in arhitekturni vidik osvetljevanja. Z ocenami afektivne kakovosti slikovnih prikazov smo predstavili in proučevali temeljna afektivna stanja anketiranih. Ugotovitve kažejo, da so se anketiranci pri večini predlogov strinjali pri ocenah spremenljivk »prijetnost« in »pozornost. Statistika pokaže med konceptoma značilne razlike pri ocenah obeh spremenljivk. Pri neposredni primerjavi obeh konceptov smo ugotovili, da je naklonjenost anketirancev do določenega osvetlitvenega koncepta odvisna tudi od mestne lokacije. S člankom želimo poudariti pomen nočne podobe mesta pri razvoju prihodnjih strategij osvetlitve, ki temeljijo na polprevodniških virih svetlobe.

    Full Text Available This study aimed to analyze the cost/benefit of tax incentives and performance indicators of Grendene S/A footwear company in the period of 2010 to 2014. The research is justified by the importance of companies seeking techniques and methodologies that are more advantageous corporately to achieve better performance. In this sense, the accounting is shown as an important tool, acting as a source of information for decision-making and wealth measurement of their investors. The methodology will be through case study in a company in the footwear sector, listed on the BM & FBovespa, with data in the periods of 2010 to 2014 available at the base of Economatica and the Financial Statements. Having the data has been identified, the modalities of tax incentives that the company benefited during the study, as well as the traditional performance indicators. To analyze the cost/benefit of tax incentives was used data from DVA and tax subsidies provided in the notes to DFPs. The results show that the company needs a constant and effective monitoring of the costs and benefits of tax waiver. Also identifies that the value of tax incentives received does not equal proportion the generation of net wealth. The results of this study confirm the theoretical basis that the benefits brought by tax incentives outnumber the costs of tax waiver, but may represent a dangerous dependence as to jeopardize the continuity of the company if they were removed.

  5. Application of Three Bioinspired Optimization Methods for the Design of a Nonlinear Mechanical System

    Directory of Open Access Journals (Sweden)

    Romes Antonio Borges

    2013-01-01

    Full Text Available The present work focuses on the optimal design of nonlinear mechanical systems by using heuristic optimization methods. In this context, the nonlinear optimization problem is devoted to a two-degree-of-freedom nonlinear damped system, constituted of a primary mass attached to the ground by a linear spring and a secondary mass attached to the primary system by a nonlinear spring. This arrangement forms a nonlinear dynamic vibration absorber (nDVA, which is used in this contribution as a representative example of a nonlinear mechanical system. The sensitivity analysis of the suppression bandwidth, namely, the frequency range over which the ratio of the main mass displacement amplitude to the amplitude of the forcing function is less than unity, with respect to the design variables that characterize the nonlinear system based on the first order finite differences is presented. For illustration purposes the optimization problem is written as to maximize the suppression bandwidth by using three recent bioinspired optimization methods: Bees Colony Algorithm, Firefly Colony Algorithm, and Fish Swarm Algorithm. The results are compared with other evolutionary strategies.

    The aim of the study was to assess the usefulness of bedside examination for screening of vestibular and balance system for occupational medicine purposes. Study group comprised 165 patients referred to Audiology and Phoniatric Clinic due to vestibular and/or balance problems. Caloric canal paresis of 19% was the cut off value to divide patients into 43 caloric-positive vestibular subjects and 122 caloric-negative patients. The latter group comprised 79 subjects revealing abnormalities of videonystagmographic (VNG) oculomotor tests (central group) and 43 subjects with normal VNG. Vestibular and balance symptoms were collected. Five tests were included to bedside examination: Romberg and Unterberger tests, Head Impulse Test (HIT), Dynamic Visual Acuity (DVA) and gaze nystagmus assessment. Vestibular and balance symptoms were reported by 82% of vestibular, 73% of central and 40% of VNG-normal patients. Thirteen out of 18 VNG-normal but symptomatic subjects (73%) had abnormal tests in clinical assessment. The sensitivity of bedside test set for vestibular pathology was 88% as compared to caloric test and 68% for central pathology as compared to VNG oculomotor tests. The combination of 5 bedside tests reveal satisfactory sensitivity to detect vestibular abnormalities. Bedside examination abnormalities are highly correlated with vestibular/balance symptoms, regardless the normal results of VNG. Thus, this method should be recommended for occupational medicine purposes. This work is available in Open Access model and licensed under a CC BY-NC 3.0 PL license.

    The imaging and surgical literature has confusing association rates for the association between sporadic intracranial cavernous malformations (CMs) and developmental venous anomalies (DVAs). In this study, our purpose was to determine the association rate using ultra-high-resolution C-arm flat-detector CT angiography (FDCTA) and compare it with literature. Fifty-eight patients with 60 sporadic intracranial CMs that underwent an FDCTA study were included in our retrospective study. Re-evaluation of radiological data was performed based on the criteria defined by authors. Isotropic volumetric reconstructions with ultra-high resolution (voxel size of 102 μm{sup 3} for initial; 67 μm{sup 3} and 32 μm{sup 3} for further evaluation) were used for assessment. Sixteen patients underwent surgery for excision of their CMs. Fifty-one of all patients (87.9 %) were associated with a DVA. Undefined local venous structures (UD-LVSs) were observed in the remaining 7 patients (12.1 %). The strength of interobserver agreement was excellent [kappa(k) coefficient = 0.923]. Ultra-high-resolution FDCTA evaluation of CMs and DVAs reveals 3-fold higher association rate compared to the literature. FDCTA for patients with sporadic CMs could help identify the associated DVAs that remained undetected or unclear with other imaging modalities, which can be useful in decision-making processes, planning surgery, and during operation.

    Full Text Available Le présent texte étudie les formes d’expansion urbaine dans les provinces européennes de l’Empire ottoman depuis la moitié du xixe siècle. Dans le cadre des réformes entreprises par l’Empire, l’octroi de droits civiques et politiques à tous les sujets ottomans, le “décollage économique” et la croissance démographique encouragent l’émergence de nouveaux comportements socio-économiques : grâce à la réforme du droit foncier et l’afflux d’investissements dans le secteur immobilier de la part des particuliers, des communautés ou des organismes publics, l’espace urbain est réaménagé et “modernisé”. L’expansion des villes préoccupait les officiers ottomans de bonne heure. La première réglementation moderne d’urbanisme mise en place entre 1848 et 1891 définit les règles selon lesquelles de nouveaux quartiers urbains peuvent être formés. D’après des études sur les villes côtières, ainsi que sur la plupart des villes de l’intérieur des provinces européennes de l’Empire, l’accroissement urbain s’accompagne d’une forte activité de groupes minoritaires pour leur installation résidentielle dans de nouveaux quartiers, très souvent encouragée par les autorités locales. L’installation prend des formes variées, parfois créant des quartiers non pas étanches mais à dominante chrétienne ou juive, parfois parfaitement mixtes. Les variantes rencontrées évoquent les particularités historiques et géographiques de chaque ville ; elles s’expliquent aussi par des stratégies des autorités locales et des besoins ou aspirations des groupes sociaux et ethniques qui les revendiquent. On étudiera l’extension planifiée de trois villes côtières et fortifiées : Volos et Kavala, petites villes dotées d’une importante fonction portuaire où la communauté grecque orthodoxe suscita la création de nouveaux quartiers ; Salonique (Thessalonique qui connut une expansion

    Full Text Available Il trasporto di animali all'interno dello stesso paese e tra paesi, regioni e continenti si incrementa significativamente e si evolve nella sua natura. Le statistiche dell'International Trade Centre of the United Nations Conference on Trade and Development and the World Trade Organization mostrano che il valore del commercio mondiale di animali vivi ammontava a 8,7 bilioni di dollari americani nel 2000 e a 12,1 bilioni di dollari americani nel 2005. Questa cifra già enorme aumenterebbe se fossero presi in considerazione gli animali degli zoo, la fauna selvatica e il traffico illecito.La storia del trasporto animale risale a migliaia di anni fa. Resta tutt'oggi molto praticato però con le misure appropriate a tutela del benessere degli animali. Nel 21mo secolo, quello che cambia è la natura stessa del trasporto (terra, aria e mare, il volume di traffico e la coscienza sociale a proposito di tematiche come il benessere e la richiesta che gli animali vengano trattati in maniera umana e conformemente ai più opportuni sistemi moderni. Questo ha incrementato i volumi dei trasporti creando una condizione senza precedenti per quanto riguarda il rischio di diffusione di malattie infettive, incluse quelle trasmissibili all'uomo.Il centro dell'interesse pubblico sul benessere animale riguarda fattori come la carenza di infrastrutture e di investimenti per quando riguarda la formazione, la ricerca e il miglioramento degli standard, così come l'indifferenza e la negligenza. Le ditte per il trasporto di animali vivi vengono diffidate quando non provvedono a queste mancanze.Fortunatamente, un numero di paesi ha anticipato queste problematiche ed ha introdotto una serie di attività a supporto di pratiche atte a migliorare il benessere degli animali. Molti hanno ammesso la chiara connessione tra benessere animale, sanità e pratiche d'allevamento, ed hanno istituito una politica adatta a ricomprendere queste attività all'interno di un servizio pubblico

    The Carbonaceous Aerosols and Radiative Effects Study (CARES) took place in the Sacramento Valley of California in summer 2010. We present results obtained at Cool, CA, the T1 site of the project ({approx}40 km downwind of urban emissions from Sacramento), where we deployed an Aerodyne high resolution time-of-flight aerosol mass spectrometer (HR-ToF-AMS) in parallel with complementary instrumentation to characterize the sources and processes of submicron particles (PM1). Cool is located at the foothill of the Sierra Nevada Mountains, where intense biogenic emissions are periodically mixed with urban outflow transported by daytime southwesterly winds from the Sacramento metropolitan area. The particle mass loading was low (3.0 {micro}gm{sup -3} on average) and dominated by organics (80% of the PM1 mass) followed by sulfate (9.9 %). Organics and sulfate appeared to be externally mixed, as suggested by their different time series (r2 = 0.13) and size distributions. Sulfate showed a bimodal distribution with a droplet mode peaking at {approx}400nm in vacuum aerodynamic diameter (Dva), and a condensation mode at {approx}150 nm, while organics generally displayed a broad distribution in 60-600nm (Dva). New particle formation and growth events were observed almost every day, emphasizing the roles of organics and sulfate in new particle growth, especially that of organics. The organic aerosol (OA) had a nominal formula of C{sub 1}H{sub 1.38}N{sub 0.004}O{sub 0.44}, thus an average organic mass-to-carbon (OM/OC) ratio of 1.70. Two different oxygenated OA (OOA, 90% of total OA mass) and a hydrocarbon-like OA (HOA, 10 %) were identified by Positive matrix factorization (PMF) of the high resolution mass spectra. The more oxidized MO-OOA (O/C = 0.54) corresponded to secondary OA (SOA) primarily influenced by biogenic emissions, while the less oxidized LO-OOA (O/C = 0.42) corresponded to SOA associated with urban transport. The HOA factor corresponded to primary emissions mainly

    Mineral surfaces exposed to moist air stabilize nanometer- to micrometer-thick water films. This study resolves the nature of thin water film formation at multifaceted hematite (α-Fe2O3) nanoparticle surfaces with crystallographic faces resolved by selected area electron diffraction. Dynamic vapor adsorption (DVA) in the 0-19 Torr range at 298 K showed that these particles stabilize water films consisting of up to 4-5 monolayers. Modeling of these data predicts water loadings in terms of an "adsorption regime" (up to 16 H2O/nm(2)) involving direct water binding to hematite surface sites, and of a "condensation regime" (up to 34 H2O/nm(2)) involving water binding to hematite-bound water nanoclusters. Vibration spectroscopy identified the predominant hematite surface hydroxo groups (-OH, μ-OH, μ3-OH) through which first layer water molecules formed hydrogen bonds, as well as surface iron sites directly coordinating water molecules (i.e., as geminal η-(OH2)2 sites). Chemometric analyses of the vibration spectra also revealed a strong correspondence in the response of hematite surface hydroxo groups to DVA-derived water loadings. These findings point to a near-saturation of the hydrogen-bonding environment of surface hydroxo groups at a partial water vapor pressure of ∼8 Torr (∼40% relative humidity). Classical molecular dynamics (MD) resolved the interfacial water structures and hydrogen bonding populations at five representative crystallographic faces expressed in these nanoparticles. Simulations of single oriented slabs underscored the individual roles of all (hydro)oxo groups in donating and accepting hydrogen bonds with first layer water in the "adsorption regime". These analyses pointed to the preponderance of hydrogen bond-donating -OH groups in the stabilization of thin water films. Contributions of μ-OH and μ3-OH groups are secondary, yet remain essential in the stabilization of thin water films. MD simulations also helped resolve crystallographic

Dokumenti iz arhiva franjevačkog samostana u Cresu svjedoče da je 1441. godine „Ser Andrea Moisenich“ mijenjao vrt za kuću s „Nobilis Ser Stefano de Petris“ koji je palaču Petris izgradio prije 1405. godine, prema čemu bi današnja kuća Moise mogla biti starija palača Petris. Građevina nosi grbove obije obitelji iz istog razdoblja pa je mogla funckionirati kao dvo-obiteljska, što je čest slučaj i u Veneciji na primjerima većih palača s dva rezidencijalna kata i dva dvorišta, elementima koje posjeduje i kuća Moise. Kuća Moise najveća je stambena građevina renesansnog Cresa, u gabaritima usporediva s istaknutim primjerima većih palača u dalmatinskim gradovima. Zbog velikih preinaka, slabije očuvanosti izvornih značajki i umanjene reprezentativnosti nije bila predmetnom znanstvenih i stručnih istraživanja te nisu bile poznate njezine osnovne karakteristike.

    Full Text Available The usefulness of financial statements depends, fundamentally, on the degree of relevance of the information they disclose to users. Thus, studies that measure the relevance of accounting information to the users of financial statements are of some importance. One line of research within this subject is in ascertaining the relevance and importance of accounting information for the capital markets: if a particular item of accounting information is minimally reflected in the price of a share, it is because this information has relevance, at least at a certain level of significance, for investors and analysts of the capital markets. This present study aims to analyze the relevance, in the Brazilian capital markets, of the information content of the Value Added Statement (or VAS - referred to in Brazil as the Demonstração do Valor Adicionado, or DVA. It analyzed the ratio between stock price and Wealth created per share (WCPS, using linear regressions, for the period 2005-2011, for non-financial listed companies included in Melhores & Maiores ('Biggest & Best', an annual listing published by Exame Magazine in Brazil. As a secondary objective, this article seeks to establish whether WCPS represents a better indication of a company's result than Net profit per share (in this study, referred to as NPPS. The empirical evidence that was found supports the concept that the VAS has relevant information content, because it shows a capacity to explain a variation in the share price of the companies studied. Additionally, the relationship between WCPS and the stock price was shown to be significant, even after the inclusion of the control variables Stockholders' equity per share (which we abbreviate in this study to SEPS and NPPS. Finally, the evidence found indicates that the market reacts more to WCPS (Wealth created per share than to NPPS. Thus, the results obtained give some indication that, for the Brazilian capital markets, WCPS may be a better proxy

    The complement factor H (CFH) tyrosine 402 histidine (Y402H, rs1061170) variant is known to be significantly associated with age-related macular degeneration (AMD). Whether this genetic variant may impact retinal blood flow regulation is largely unknown. This study investigated whether flicker-induced vasodilation, an indicator for the coupling between neural activity and blood flow, is altered in subjects carrying the rs1061170 risk allele. One hundred healthy subjects (aged between 18 and 45 years) were included in this study. Retinal blood flow regulation was tested by assessing retinal vessel calibres in response to stimulation with diffuse flicker light. Retinal vascular flicker responses were determined with a Dynamic Vessel Analyzer (DVA). In addition, genotyping for rs1061170 was performed. Eighteen subjects were homozygous for the risk allele C, 50 were homozygous for the ancestral allele T, and 31 subjects were heterozygous (CT). One subject had to be excluded from data evaluation, as no genetic analysis could be performed due to technical difficulties. Baseline diameters of retinal arteries (p = 0.39) and veins (p = 0.64) were comparable between the three groups. Flicker-induced vasodilation in both retinal arteries (p = 0.38) and retinal veins (p = 0.62) was also comparable between the three studied groups. Our data indicate that homozygous healthy young carriers of the C risk allele at rs1061170 do not show abnormal flicker-induced vasodilation in the retina. This suggests that the high-risk genetic variant of CFH polymorphism does not impact neuro-vascular coupling in healthy subjects. © 2014 The Authors.

    Full Text Available BACKGROUND: This study assessed whether the number of comorbid conditions unrelated to diabetes was associated with a delay in therapeutic progression of diabetes treatment in Australian veterans. METHODOLOGY/PRINCIPAL FINDINGS: A retrospective cohort study was undertaken using data from the Australian Department of Veterans' Affairs (DVA claims database between July 2000 and June 2008. The study included new users of metformin or sulfonylurea medicines. The outcome was the time to addition or switch to another antidiabetic treatment. The total number of comorbid conditions unrelated to diabetes was identified using the pharmaceutical-based comorbidity index, Rx-Risk-V. Competing risk regression analyses were conducted, with adjustments for a number of covariates that included age, gender, residential status, use of endocrinology service, number of hospitalisation episodes and adherence to diabetes medicines. Overall, 20,134 veterans were included in the study. At one year, 23.5% of patients with diabetes had a second medicine added or had switched to another medicine, with 41.4% progressing by 4 years. The number of unrelated comorbidities was significantly associated with the time to addition of an antidiabetic medicine or switch to insulin (subhazard ratio [SHR] 0.87 [95% CI 0.84-0.91], P<0.001. Depression, cancer, chronic obstructive pulmonary disease, dementia, and Parkinson's disease were individually associated with a decreased likelihood of therapeutic progression. Age, residential status, number of hospitalisations and adherence to anti-diabetic medicines delayed therapeutic progression. CONCLUSIONS/SIGNIFICANCE: Increasing numbers of unrelated conditions decreased the likelihood of therapeutic progression in veterans with diabetes. These results have implications for the development of quality measures, clinical guidelines and the construction of models of care for management of diabetes in elderly people with comorbidities.

    Given that meticulous implant prosthodontic procedures are recommended to obtain the best possible intraoral fit, the die systems used for multi-implant casts warrant further investigation. PURPOSE. The purpose of this in vitro study was to compare the accuracy of implant casts fabricated from 3 conceptually different die systems at the solid, sectioned, and repeated stages. Thirty direct transfer implant impressions were made of the master cast with a polyether impression material. Ten experimental implant casts were fabricated for each of the 3 different die systems tested: double-pour (Pindex), plastic base (DVA), and die tray (KO Tray). The solid experimental casts were sectioned and then removed from the die system 30 times. Linear distances between steel balls placed on each abutment replica were measured with a traveling microscope to determine the accuracy of the experimental casts at different stages. Data were analyzed with repeated-measures analysis of variance (alpha=.05) and the post hoc Ryan-Einot-Gabriel-Welsch multiple-range test (REGWQ). Repeated-measures analysis of variance revealed a significant interaction between the die systems and different stages (P=.0432). REGWQ showed the die tray system to be significantly more accurate at the solid than at the sectioned and repeated stages. The die tray system was significantly less accurate than the double-pour and plastic base systems at the sectioned stage. Within the limitations of this study, the use of a double-pour or plastic base die system is recommended when sectioned dies are needed for a multi-implant-retained prosthesis.

    Many patients requiring antiviral treatment of chronic hepatitis C (HCV) have a background of significant injection drug use (IDU). In a proportion of patients, IDU results in difficulty with blood collection from conventional sites. We audited patients from the Liver Clinics and Drug Health Pharmacotherapy Service of The Royal Prince Alfred Hospital (RPAH) to determine the incidence of difficulty with blood collection. This survey identified the need for an innovative venous access strategy to better manage this group of patients. An external jugular venepuncture (EJV) protocol and education package was developed in collaboration with the Department of Anaesthetics, Gastroenterology and Liver Centre and HCV clinical nurse consultants (CNC). RPAH policy and procedure committee approved the protocol and patient information sheet. Patients with a history of difficulty with blood collection were eligible for the protocol. Patient satisfaction surveys were conducted. The initial survey of patients from the liver clinics and pharmacotherapy service identified that 48 percent had difficulty with blood collection from conventional sites. In the period October 2002 to July 2006, 29 patients (89 percent with history of IDU) were referred for EJV assessment. Major indications for EJV were for blood testing for initiation and monitoring of antiviral therapy and ongoing assessment of HCV infected patients. No adverse events resulted from the procedure. All patients surveyed report high levels of satisfaction with the technique compared to previous venous access attempts. EJV improves access to antiviral therapy and is a safe and effective technique for patients with difficult venous access (DVA). In addition, we have utilised EJV for post-transplant care of patients and used external jugular vein cannulation as vascular access for contrast imaging in hepatocellular carcinoma (HCC) assessment.

U vezi s tim moguće je delovati u dva smera: zamenom konvencionalnih goriva alternativnim i konstrukcionim izmenama na motorima radi smanjenja emisije i potrošnje goriva. Jedna od mogućnosti konstrukcionog poboljšanja motora je i smanjenje mehaničkih gubitaka, koji kod današnjih konstrukcija još uvek imaju znatan udeo u gubicima, pogotovo na parcijalnim režimima. Treba naglasiti da kompleksni problemi smanjenja potrošnje goriva i emisije izduvnih gasova motora (vozila mogu da se reše samo spregom razvoja automobilske i naftne industrije. / Ecological trends and movements in the modern world grow stronger and more active, due to a real danger of Earth pollution. One of the main sources of pollution are IC engines and their influence on environment is significant. However, conventional combustion engines still are and will be dominant powering systems for numerous future applications. Two solutions are possible answers to this problem: first, the replacement of conventional fuels by alternative ones and second, modifications on the IC engine design in order to decrease fuel emission and consumption. One of the solutions for the improvement of IC engine design is the modification of engine parts or their design, with great influence on the decrease of mechanical losses, especially on partial rating. Therefore, it is important to say that complex problems of engine (automotive decrease of fuel consumption and exhaust gas emission can be solved only by simultaneous development of oil and engine (automotive industry.

    Wei and Hemmings [2000: Nat Genet 25:376-377], using 80 British parent-offspring trios, identified a number of NOTCH4 variants and haplotypes that showed statistically significant evidence of association to schizophrenia. Specifically, the 10 repeat allele of a (CTG)(n) marker and the 8 repeat allele of a (TAA)(n) marker demonstrated excess transmission to affected individuals; SNP21 and haplotypes SNP2-(CTG)(n) and SNP12-SNP2-(CTG)(n) also showed significant associations. In an attempt to replicate these findings, we tested for linkage and association between the same five markers used by Wei and Hemmings in 166 families collected from a multi-center study conducted by the Department of Veterans Affairs (DVA) Cooperative Study Program (CSP). The families include 392 affected subjects (schizophrenia or schizoaffective disorder, depressed) and 216 affected sibling pairs. The families represent a mix of European Americans (n = 62, 37%), African Americans (n = 60, 36%), and racially mixed or other races (n = 44, 27%). We identified moderate evidence for linkage in the pooled race sample (LOD = 1.25) and found excess transmission of the 8 (P = 0.06) and 13 (P = 0.04) repeat alleles of the (TAA)(n) marker to African American schizophrenic subjects. The 8 and 13 repeat alleles were previously identified to be positively associated with schizophrenia by Wei and Hemmings [2000: Nat Genet 25:376-377] and Sklar et al.

    The amplitude of spontaneous retinal venous pulsations (SRVP) is known to be affected by intraocular pressure (IOP), retinal venous pressure, and intracranial pressure (ICP). This study characterized SRVPs adjacent to the disc and quantified changes in the amplitude of these pulsations during IOP manipulation in normal subjects. The study included 12 subjects (40 ± 15, 4 females, 8 males). Baseline IOP (range 10-25 mmHg) was measured and SRVP recorded using the dynamic retinal vessel analyzer (DVA). IOP was lowered using aproclonidine 0.5% and measured every 15 min, followed by dynamic recording of SRVP. Two subjects were also tested with timolol 0.5%, and three were treated with a placebo drop. Mean amplitude of SRVP was determined within each sample at the same site. Blood pressure and heart rate were tracked continuously. Amplitude of SRVP decreased in all subjects with reduction of IOP with aproclonidine and timolol. Mean SRVP amplitude was 8.5 ± 6 μm at baseline and reduced to 2.5 ± 1.8 μm after 45 min (p blood pressure, and heart rate did not change significantly from the baseline. Analysis of waveforms showed a slight phase shift only (150 ± 78.5 ms, p = 0.93) between disc veins and adjacent retinal vein. SRVPs in the peripapillary retina have similar waveform characteristics to those at the disc. SRVP amplitudes are reduced by manipulation of IOP downwards with pharmacological intervention. The relationship was consistent in all individuals tested for two classes of drugs and was independent of BP or heart rate changes.

Njihovu djelatnost na otoku potvrđuju kako suvremene matične knjige, tako i spomenici – prikazi zidarskih i klesarskih alata na nadgrobnoj ploči u crkvi sv. Marka te na nadvratniku kuće majstora Franića Lorencina iz 1660. godine. Analiza katastarskih i topografskih nacrta iz 1824. i 1833. godine pokazuje da južni zid crkve istočno od prigrađene kapele Gospe od Ružarija zasebnim usmijerenjem odstupa od pravca ostalog dijela zida, što upućuje na zaključak da je ovaj dio strukture pripadao ranijem, po svemu sudeći srednjovjekovnom sloju građevine koja bi pregradnjom, dokumentiranoj u vizitaciji iz 1670. godine, bila proširena i produžena prema zapadu. Ovu mogućnost, koju bi trebala potvrditi neka buduća arheološka istraživanja lokaliteta, osnažuje učestalost takvih pregradnji na primjerima crkava XVII. i XVIII. stoljeća na otoku Ugljanu, a posebno situacija na tipološki analognom primjeru crkve sv. Lovre u Lukoranu na istom otoku iz 1632. godine. Otvorena predvorja također su osobitost ovih crkava, s tom razlikom da su na hrvatskom priobalju karakteristične upravo za područja Istre i Kvarnera kojemu otok Silba i zemljopisno gravitira. Silbenska je „lopica“ bila specifično izduženog tlocrta te je na pročelju imala dva simetrična niza od po tri nosača s aksijalnim glavnim ulazom u trijem, odnosno crkvu. Radi neposredne prijetnje od upada turskih gusara trijem vjerojatno nije bio prigrađen prije kraja 17. stoljeća kada ove prijetnje prestaju. Naime, toranj zvonika zasigurno je korišten kao obrambena kula, kojoj bi takva prigradnja umanjivala fortifikacijski značaj i vizualnu kontrolu ulaza u crkvu. Uvidom u arhitektonsku strukturu zvonika zapažena su dva različita građevna sloja od kojih starijem pripada trup zvonika, dok se drugi odnosi na strukturu piramide osovljene na plitkom kvadratnom tamburu.

    In order to determine which areas of cancer screening are currently receiving greatest emphasis in different parts of the world a Medline search of the literature for the period 2000-2002 was performed, concentrating attention on research into all aspects of efforts for early detection of tumours, with especial attention to methodology, motivation (including awareness of utility in the general populace and in minority groups), and intervention (professional training and general education). Focus on the skin, lung, cervix, breast, ovary + endometrium, oral cavity-oesophagus, gastric, colorectal, kidney + urinary tract and prostate, demonstrated large numbers of journals to be publishing papers in the field, with 10, 33, 130, 53, 24, 21, 6, 81, 12 and 58, respectively, in the period investigated, the grand total being 259. The average numbers of papers/journal ranged from 1.0-2.4 with only 15-35% appearing in journals with wide coverage. With the exception of oral, oesophageal and gastric cancer screening, an approximately 50% contribution in all areas was made by scientists in the US, followed by Europe (31% overall,) Asia (11%) then Australasia, Central and South America and Africa (3%, 2% and 1%, respectively). Clear differences were evident with the organ regarding specific topics receiving attention, most publications concerning the lung, ovary and urological tract dealing with detection methods. With the cervix and colorectum this topic accounted for half of the papers with especial attention to the relative advantages of the PAP smear, HPV testing and direct visual acetic acid (DVA) in the one, and FOBT and endoscopy in the other. Another major focus was found to be minority attitudes to breast, prostate and cervical screening in the US, whereas only few papers were found dealing with practical intervention, targeting professionals or screenees to increase participation in screening programs.

    Full Text Available Prostorni položaj težišta vozila i rotacije karoserije značajni su za analizu dinamike, ponašanje na putu, oscilatornu udobnost vozila, bezbedno odvijanje saobraćaja i sl. Pomenuti parametri se u fazi projektovanja vozila određuju metodama dinamičke simulacije, a kod izvedenih vozila merenjima u stvarnim eksploatacionim uslovima. Problem koji je u ovom radu razmotren odnosi se na praktična merenja parametara kretanja vozila. Naime, translatorne koordinate težišta vozila se, uobičajeno, utvrđuju na osnovu registrovanih linearnih ubrzanja težišta vozila (koja se kasnije, jednom ili dva puta, integrale radi izračunavanja brzine ili pomeranja, a uglovi rotacije karoserije se najčešće, mere žiroskopski stabilisanim platformama. Problem koji se pri tome javlja je cena pomenutih platformi (do sto hiljada evra, pa je retko koja institucija njima opremljena. U ovom radu nastojano je da se utvrde parametri kretanja vozila na osnovu šest registrovanih linearnih ubrzanja karakterističnih tačaka vozila. / Spatial position of vehicle C.G. as well as angular parameters of body rotation are of major importance for analysis of vehicle dynamics, handling vibrational comfort, safe service in traffic etc. The mentioned parameters are determined by use of methods of dynamic simulation in phase of development, and by means of test measurement for vehicles in real service conditions. The problem that is to be taken into consideration here is related to practical measurement of vehicle motion parameters. Translational coordinates of vehicle C.G. are usually measured on the basis of registered linear accelerations of vehicle C.G.

Riječ je o „greškama u koracima“ koje dovode do ništetnosti odluka skupštine d.o.o.-a o kojima se u domaćoj pravnoj književnosti do sada nije sustavno raspravljalo. Ishodište za razradu ove problematike temelji se na okolnosti da je u odredbi članaka 448. ZTD-a propisano da se na ništetnost odluka skupštine d.o.o.-a na odgovarajući način primjenjuju odredbe o ništetnosti odluka glavne skupštine d.d.-a. Kako su procesnopravne razlike djelovanja glavne skupštine d.d.-a i skupštine d.o.o.-a jedna su od temeljnih razlika ova dva tipa društava kapitala spomenuto pozitivnopravno uređenje dovodi do pravne nesigurnosti i pogrešnih tumačenja. U prvom dijelu rada daje se kronološki pregled normativnog uređenja ništetnosti odluka skupštine d.o.o-a. Potom se doktrinarno razgraničavaju ništetne odluke od drugih odluka s nedostatkom. Zatim se svaka odredba o ništetnosti odluka glavne skupštine d.d.-a testira u kontekstu d.o.o.-a i potom izrijekom formulira odredba koja vrijedi samo za d.o.o. Osim domaćeg prava analiziraju se i rješenja iz poredbenog prava (osobito njemačkog jer se domaće pravo u velikoj mjeri preklapa s rješenjima iz poredbenih prava. U zaključku se daju smjernice za praktičnije de lege ferenda uređenje ZTD-a u pogledu ništetnosti odluka skupštine d.o.o.-a.

Zanimljivo je da se politička tolerancija ne može objasniti razvojem različitih dimenzija građanske svijesti učenika.To bi moglo značiti da se ona kod mladih razvija kao modus vivendi u društvu, a ne kao osmišljeno razumijevanje svijesti o ljudskim pravima i demokratskim normama. Dalje je pokazano da spol učenika i “školsko učenje” (zadaci odgoja daju važan doprinos razvoju dimenzija građanske svijesti, ali ne i prakse građanstva, dok SES-učenika i “školska klima” imaju važan utjecaj na razvoj dimenzija prakse građanstva. To znači da školski uvjeti djeluju diferencirano na razvoj različitih dimenzija građanstva kod učenika. Taj rezultat na određen način razjašnjava uočenu dilemu u literaturi oko utjecaja školske klime. Jasno je da bi ova istraživanja trebalo nastaviti i još sustavnije razraditi školske uvjete i neke druge strukturalne karakteristike mladih.

    Highlights: • The test bed allows for the validation of real-time image processing techniques. • Offers FPGA (FlexRIO) image processing that does not require CPU intervention. • Is fully compatible with the architecture of the ITER Fast Controllers. • Provides flexibility and easy integration in distributed experiments based on EPICS. - Abstract: Image diagnostics are becoming standard ones in nuclear fusion. At present, images are typically analyzed off-line. However, real-time processing is occasionally required (for instance, hot-spot detection or pattern recognition tasks), which will be the objective for the next generation of fusion devices. In this paper, a test bed for image generation, acquisition, and real-time processing is presented. The proposed solution is built using a Camera Link simulator, a Camera Link frame-grabber, a PXIe chassis, and offers software interface with EPICS. The Camera Link simulator (PCIe card PCIe8 DVa C-Link from Engineering Design Team) generates simulated image data (for example, from video-movies stored in fusion databases) using a Camera Link interface to mimic the frame sequences produced with diagnostic cameras. The Camera Link frame-grabber (FlexRIO Solution from National Instruments) includes a field programmable gate array (FPGA) for image acquisition using a Camera Link interface; the FPGA allows for the codification of ad-hoc image processing algorithms using LabVIEW/FPGA software. The frame grabber is integrated in a PXIe chassis with system architecture similar to that of the ITER Fast Controllers, and the frame grabber provides a software interface with EPICS to program all of its functionalities, capture the images, and perform the required image processing. The use of these four elements allows for the implementation of a test bed system that permits the development and validation of real-time image processing techniques in an architecture that is fully compatible with that of the ITER Fast Controllers

    Full Text Available Uma série de 95 crianças hidrocefálicas foram submetidas à derivação ventriculoperitoneal (DVP com válvula no período de dezembro de 1965 a novembro de 1969. Os resultados obtidos são analisados e comparados com os obtidos mediante derivação ventriculoatrial (DVA. Das crianças operadas, 54 estão vivas e com a hidrocefalia compensada, 9 faleceram, não sendo possível estabelecer as condições atuais das 32 restantes. Com a derivação para o peritônio foram evitadas as severas complicações vasculares e cardiopulmonares observadas com a derivação para a cvidade cardíaca. O número de revisões cirúrgicas é menor nos pacientes submetidos à DVP com válvula. Além disso, as infecções no sistema de drenagem ventriculoperitoneal provocam quadros menos graves e de mais fácil solução, que os observados na derivação ventriculoatrial. A análise das condições pré-operatórias, das complicações e dos resultados finais permitiram algumas conclusões: 1 o uso de válvula unidirecional, no sistema de derivação ventriculoperitoneal, dificulta a oclusão da extremidade distal do sistema de drenagem; 2 pode-se esperar bons resultados, sem necessidade de revisão cirúrgica, em cêrca de 42,35% das crianças hidrocefálicas submetidas à DVP com válvula; 3 as derivações ventriculoperitoneais com válvula, quando comparadas às derivações ventriculoatriais, considerando um grupo de crianças hidrocefálicas operadas nos mesmos Serviços, em condições semelhantes, com mesmo tempo de seguimento — foram as que proporcionaram melhores resultados; 4 os casos estudados permitem constatar, portanto, que a DVP com válvula, constitui atualmente a terapêutica cirúrgica mais apropriada da hidrocefalia infantil.

    The purpose of this study was to analyze the effects of fatigue driving and drunk driving on drivers' physical characteristics; to analyze the differences in drivers' physical characteristics affected by different kinds of fatigue; and to compare the differences in the effects of the 2 driving states, fatigue driving and drunk driving. Twenty-five participants' physical characteristics were collected under 5 controlled situations: normal, tired driving, drowsy driving, drowsiness + tired driving, and drunk driving. In this article, fatigue driving refers to tiredness and drowsiness and includes 3 situations: tired driving, drowsy driving, and drowsiness + tired driving. The drivers' physical characteristics were measured in terms of 9 parameters: systolic blood pressure (SBP), heart rate (HR), eyesight, dynamic visual acuity (DVA), time for dark adaption (TDA), reaction time to sound (RTS), reaction time to light (RTL), deviation of depth perception (DDP), and time deviation of speed anticipation (TDSA). They were analyzed using analysis of variance (ANOVA) with repeated measures. Binary logistical regression analysis was used to explain the relationship between drivers' physical characteristics and the two driving states. Most of the drivers' physical characteristic parameters were found to be significantly different under the influence of different situations. Four indicators are significantly affected by fatigue driving during deep fatigue (in decreasing order of influence): HR, RTL, SBP and RTS. HR and RTL are significant in the logistical regression model of the drowsiness + tired driving situation and normal situations. Six indicators of the drivers' physical characteristics are significantly affected by drunk driving (in decreasing order of influence): SBP, RTL, DDP, eyesight, RTS, and TDSA. SBP and DDP have a significant effect in the logistical regression model of the drunk driving situation and the normal situation. Both fatigue driving and drunk driving

    Full Text Available Dans la Basse Vallée du Cañete, comme sur l'ensemble de la Côte péruvienne, les entreprises associatives installées par la Réforme Agraire au début des années 70, ont été parcellisées entre les coopérateurs, transformant ainsi profondément la structure agraire. L'article analyse l'origine et les causes de ce processus de démembrement, résultat à la fois d'une nette volonté politique, d'une conjoncture économique défavorable, des difficultés d'organisation rencontrées par les coopératives, de la volonté des coopérateurs d'avoir accès à la propriété privée, mais aussi de la confrontation des systèmes de production: grande coopérative/moyenne propriété modernisée/petite propriété diversifiée. La mise en place du nouveau système de production parcellaire montre une inégale efficacité des nouveaux agriculteurs et des nouvelles structures que sont les coopératives de services. Les perspectives qui s'ouvrent à l'agriculture de la Vallée et à son organisation laissent entrevoir la possibilité d'un changement lent mais profond vers une intensification de la production si les conditions globales (stabilité du cadre légal, recherche et assistance technique au producteur, crédit et prix rémunérateurs, etc. sont favorables. En conclusion, l'article propose quelques orientations allant dans ce sens. En el Valle de Cañete, como en la Costa peruana en general, las empresas asociativas instauradas por la Reforma Agraria, al inicio de la década de los 70, fueron parceladas entre los socios, transformándose así profundamente la estructura agraria. El artículo analiza el origen y las causas de este proceso de parcelación, resultado a la vez de una voluntad política definida, de una coyuntura económica adversa, de las dificultades de organización encontradas por las cooperativas, de la voluntad de los socios de tener acceso a la 'parcela propia' pero más aún, de la confrontación de los sistemas de

V zgodnjem povojnem obdobju sta bila v Zagrebu realizirana dva velika urbanistična projekta: Ulica grada Vukovara, reprezentativni center pomembnih vladnih, administrativnih in kulturniških stavb, ter razstaviščni kompleks Zagrebškega velesejma, s katerim je bil storjen radikalen korak v širitvi mesta v južni smeri in izgradnji Novega Zagreba na desnem bregu Save. Ta dva revolucionarna projekta sta morala funkcionirati v okviru aktualnega političnega diskurza, hkrati pa je bilo potrebno sprejetje s strani najširše družbene sfere – delavskega razreda. Abstraktna arhitekturna govorica modernizma je bila za večji del te družbene sfere (ki je bila do nedavnega pretežno ruralnega značaja težko sprejemljiva. Manjši del prebivalstva je imel drugačno socialno poreklo – to so bili meščani, ki so živeli v starem mestnem jedru. To je zanje predstavljalo »pravi« Zagreb, zato so bili do novonastalih urbanističnih projektov zadržani iz drugačnega razloga. Naloga široko zastavljene medijske kampanje je bila torej nove podobe Zagreba približati obema skupinama in vzpodbuditi proces prepoznavanja novih urbanističnih projektov kot njunega mesta – spodbujati identifikacijo prebivalcev s konceptom mesta, ki je vpeto v sodobne urbanistične tokove. Da bi uspešno implementirali nove simbolične podobe Zagreba v družbeno zavest meščanov, so njihovi snovalci uporabili preizkušene mehanizme medijske propagande. Prizadevali so si, da bi postale čim bolj vidne tudi za tiste, ki ne

    Full Text Available BACKGROUND: In hippotherapy, in comparison to equitation, it is assumed that the rider is a passive element, only stimulated by mechanical impulses produced by the moving horse's back. OBJECTIVE: The aim of the study was to determine the influence of the rider on the horse's movement in hippotherapy. METHODS: Two sound thoroughbreds with a similar body shape and size (age: 19 and 14 years, withers height: 1.65 m both, weight: 548 and 500 kg participated in the study. The test group of riders consisted of twelve healthy young women (age: 23.3 ± 2.8, weight: 59.2 ± 5.3, height: 167.3 ± 4.2 without any previous horse riding experience. For each rider 36 trials in total (6 strides in 6 hippotherapy sessions held during the course of five weeks were evaluated. The movement was recorded by 4 videocameras (frequency 50 Hz. Spatiotemporal variables, the vertical displacement of selected points on the horse's limbs and the back and angle displacement of tarsus joint were analyzed by the APAS programme. Statistical processing was performed by the Statistica programme (one way ANOVA. RESULTS: In our study, we didn't find any statistically significant difference (p CONCLUSIONS: In hippotherapy, basic spatiotemporal variables of a horse's natural walking aren't influenced by the rider. As for the vertical displacement of points on the limbs and the horse's back, the results are not explicit. A larger number of horses is necessary for future study. The patient and the horse in hippotherapy are to be rather considered as interactive elements than as passive and active elements.[VÝCHODISKA: V hipoterapii je, na rozdíl od jezdectví, jezdec považován za pasivní prvek, který je stimulován impulsy, které vycházejí z pohybujícího se hřbetu koně.

    Full Text Available La Révolution Libérale prétend dès 1895 construire une éducation nationale laïque et modernisée, et s´appuie dans ce but sur les Écoles Normales qu’elle crée en 1901 et qui doivent devenir le fer de lance d´un corps enseignant laïc d´État, homogène et uni. Le processus est lent et disparate, mais respecte toujours trois orientations: une formation professionnelle uniforme censée homogénéiser le profil des enseignants, la création d´espaces de rencontres pédagogiques (assemblées, conférences, revues, bibliothèques pédagogiques devant susciter une identification de l´enseignant avec sa mission professionnelle, la valorisation sociale de la profession considérée comme rebutante. À la chute du régime libéral, en 1925, les résultats sont peu satisfaisants, même s´il existe un corps enseignant en germe. Les régimes post-libéraux, notamment la Révolution Julienne, reprennent les axes libéraux. Cependant, les graves difficultés économiques et des gouvernements souvent autoritaires, voire répressifs, à l’égard des enseignants rendent le projet difficilement réalisable. Les Écoles Normales fonctionnent laborieusement, de nouvelles filières leur ôtent le monopole de la formation, les conférences pédagogiques se font rares et si les revues pédagogiques se multiplient, elles intéressent essentiellement la minorité d´un corps enseignant désorganisé. Paradoxalement, ce sont les difficultés sociales et les abus des pouvoirs arbitraires qui rapprochent les enseignants équatoriens. Une organisation syndicale nationale voit le jour à la fin des années 1930 qui permet aux enseignants d’entrer sur la scène politique et de jouer un rôle non négligeable dans la vie du pays dans les années 1940. Le corps enseignant existe bien en 1946, moins de par l´identification avec sa mission pédagogique que de par la précarité de son statut et de la nécessité de se défendre.

    , un passato però quanto mai presente e del quale proprio un succinto esame del problema-popolo consente di illuminare alcuni aspetti rilevanti.Si dirà che la sottolineatura del carattere impolitico del moderno fa parte di una posizione di pensiero, tutto sommato, non certo nuova: minoritaria sicuramente, ma non inedita né particolarmente originale. E, per documentarlo – si aggiungerà – basta evocare i nomi dei cosiddetti nostalgici della polis, da Arendt, a Strauss, a Voegelin, e via procedendo. Saremmo alla solita contrapposizione tra sostenitori di modelli normativi di politica in alternativa l’uno rispetto all’altro, ognuno dei quali accusa l’avversario di fallacia o di tentazione ideologica. Così, però, almeno in questo saggio, non dovrebbe essere. E non solo perché queste poche pagine sono all’insegna della convinzione che argomentare (e non solo contrapporre dogmaticamente è possibile. Ma soprattutto perché l’obiettivo non è tanto di mettere a confronto modelli, quanto di operare entro quelli che la modernità ci offre e di criticarli iuxta propria principia, facendone risaltare la contraddittorietà o i vari aspetti problematici a partire dal loro interno, dalla loro logica, dalla loro struttura, più o meno sistematica. La critica di impoliticità può quindi esercitarsi in un confronto diretto con i “classici” moderni della politica e può tentare di porre in luce l’impasse nella trama teorica che essi, pur in diverso modo e anche spesso con intenti molto differenti, elaborano.Diciamo, allora, che prima di cimentarsi sul piano normativo, questo saggio si muove sul piano ermeneutico, che certo, come ben sappiamo tutti, privo di presupposti normativi non è mai. Ma chi si colloca su tale piano cerca (o dovrebbe farlo di avvicinarsi, per quanto possibile, all’oggetto e di comprenderlo in profondità, assottigliando il più possibile le pretese normative – con la consapevolezza, comunque, che, come ci ha insegnato prima di tutti

    Full Text Available Teoretiziranje o konceptu muškosti, kao karakteristike koja se pridodaje određenim vizualnim proizvodima pristupačno je u prvom redu putem proučavanja medija, kulture i praksi označavanja. Te prakse konstruiraju imaginarij s raznim posljedicama koje se manifestiraju ponajviše u načinu gledanja na pojedinu kulturu, spol, rod i slično. Melly (1986 i Mort (1988 ponajviše su govorili o novom načinu vizualnog kodiranja. George Melly je pridonio kratkim pregledom određenog seta oglasa u kojima je vidio “novo korištenje spola“ unutar kojeg su se „muškarci koristili kao pasivni seksualni objekti'“ (Melly, 1986:41. S druge strane, u tradiciji kulturnih studija, Frank Mort (1988 tvrdi da su muška tijela koja se pojavljuju u oglasima za traperice Levis prezentirana modnim kodovima i kulturom stila. Sean Nixon (1997, navodeći u svom tekstu ta dva primjera i nastavljajući se na njih, istraživao je kulturnu značajnost stvaranja slika „novog muškarca“ koje su povezane s muškim tržištem kojemu su te slike namijenjene. Slike je stavio u vezu sa stvorenim (ili bolje rečeno konstruiranim slikama muškosti i muške kulture. Nadalje, Nixon (1997 navodi knjigu The Sexuality of Men (Metcalf and Humphries, 1985, koja konceptualizira pojam muškosti govoreći da je karakteriziran slikama agresivnosti, kompetitivnosti, emocionalne neprilagođenosti i hladnoće koje su ovisne o pretjeranu naglašavanju penetrativnog seksa. Muškarci su, prema autorima, počeli kritički promišljati o muškosti, iskazivali su strah i anksioznost prema konstrukciji „muškosti“ iz tih reklama. Sukladno tome sva muška tijela izvan konstruirane „muškosti“ postaju ugrožena. Taj se koncept dalje razvijao u popularnoj kulturi, a konzumenti su ga, napadnuti takvim slikama, prihvaćali stvarajući želju prema takvu obliku muškosti, osjećajući anksioznost, strah i depresiju zbog toga što ne pripadaju toj slici ili zadovoljstvo spoznajom da oni jesu

Zvláště nás zajímalo, zda převládají zprávy o sportovcích a zda existují rozdíly ve způsobu, počtu a stylu článků o sportovcích a sportovkyních. Analyzovali jsme dva deníky a porovnávali rozsah, počet článků a fotografie. Články jsme rozřadili do tří skupin: články o sportovcích, články o sportovkyních a články o obojích současně. Podrobněji jsme sledovali jejich styl. Velkou úlohu rovněž hrají fotografie. Srovnávali jsme proto množství, typ, velikost a statický/dynamický charakter fotografií. Výsledky této studie potvrzují některé z předběžných závěrů o tom, že noviny sportovkyním poskytují méně místa, publikují o nich méně článků a věnují jim menší pozornost. Zkoumáním fotografií jsme došli k závěru, že fotografie sportovců jsou lépe umisťovány a že jsou častěji barevné. Sportovkyně jsou zobrazovány tak, aby vynikal jejich tělesný vzhled a nikoli sportovní role. The aim of our research was to establish how Slovene media report on sporting events. We were especially interested if there is a prevalence of reports about male athletes, and if there are differences in manner, amount and style of reporting between the articles about male and female athletes. We analysed two daily newspapers and compared the size, the number of articles, and the photographs. We have classified the articles into three groups; articles about male athletes, articles about female athletes and articles about both. We took a closer look at the style of writing. The photographs also play an important role. Therefore, we also compared the amount, type, size and static/dynamics of photographs. The results of this study confirm some of the preliminary conclusions that the newspapers offer less space, publish less articles and pay less attention to female athletes. By

A análise das condições pré-operatórias, das complicações e dos resultados finais permitiram algumas conclusões: 1 o uso de válvula unidirecional, no sistema de derivação ventriculoperitoneal, dificulta a oclusão da extremidade distal do sistema de drenagem; 2 pode-se esperar bons resultados, sem necessidade de revisão cirúrgica, em cêrca de 42,35% das crianças hidrocefálicas submetidas à DVP com válvula; 3 as derivações ventriculoperitoneais com válvula, quando comparadas às derivações ventriculoatriais, considerando um grupo de crianças hidrocefálicas operadas nos mesmos Serviços, em condições semelhantes, com mesmo tempo de seguimento — foram as que proporcionaram melhores resultados; 4 os casos estudados permitem constatar, portanto, que a DVP com válvula, constitui atualmente a terapêutica cirúrgica mais apropriada da hidrocefalia infantil.From December-1965 to November-1969, 95 hydrocephalic infants have been operated upon using ventriculoperitoneal shunt with valve (88 cases with a Spitz-Holter valve, 6 cases with a Hakim valve and one case with a

    Full Text Available U radu je prikazano delovanje sile prednaprezanja na armiranobetonski ram (u daljem tekstu AB ram. Posmatrani sistem je statički neodređen sa dva ukleštenja. Na njega deluje opterećenje prednaprezanje kablom silom Nk=600 kN, kao i sopstveno opterećenje. Visina rama je 6.00 m, a osovinski razmak 20.00 m. Opterećenje od sopstvene težine elemenata je od rigle i stuba. Opterećenje konstrukcije usled prednaprezanja spada u unutrašnja opterećenja, koja zamenjujemo ekvivalentnim opterećenjem koje predstavlja spoljašnje opterećenje. Proračun je izvršen metodom sila i metodom deformacija, kao i u softverskom programu 'Tower'. Metodom sila se uklanja ukleštenje i preseku se omogućava obrtanje. Statički neodređena veličina tada je moment ukleštenja. Kod metode deformacije sve statičke i deformacijske veličine izražavaju se putem izvesnog broja međusobno nezavisnih deformacijskih veličina, koje su određene iz uslova ravnoteže sistema. Broj nezavisnih deformacijskih neodređenih veličina predstavlja deformacijsku neodređenost nosača. Sve deformacijski neodređene veličine mogu se svrstati u dve grupe: prvu grupu čine uglovi obrtanja na krajevima kruto vezanih štapova, a drugu grupu komponente pomeranja čvorova. / The effects of prestressing forces on a reinforced concrete frame are shown in the paper. The structure is a statically indeterminate frame with two fixed supports. The load is due to tendon prestressing with Nk = 600 kN and due to self-weight of columns and beam. The columns height is 6.00 m and the beam span is 20.00 m. Effects of prestressing can be replaced by an external equivalent load. Calculations are performed by the force method, by the direct stiffness method and using the 'Tower' software. The rotational restraints are released at fixed supports and the restraint moments are calculated by the force method. The direct stiffness method uses the members' stiffness relations for computing member forces and

Poređenje ova dva sistema pokazalo je da rešenje sa mašinom sa podržavajućim vektorima (SVM prijemnik poboljšava robustnost sistema po cenu smanjenja brzine procesiranja. Međutim, ostvarljivi protok bita kod prijemnika sa korelatorom bio je dva puta veći nego kod prijemnika koji koristi mašinu sa podržavajućim vektorima.

    Full Text Available BACKGROUND: The one handed catching of a ball is a complex coordination ability. It requires the spatial and time adjustment of the hand according to the speed of the approaching ball. OBJECTIVE: Two main objectives were exposed in the course of the present research; namely whether and why children with Down's syndrome (DS have problems with one handed ball catching compared to the children with no impairment in motor task such as the one handed catching of a ball. METHODS: Eleven children with DS, aged 8, and 16 with no impairment, also aged 8, were required to catch 45 balls (small, medium, and large. No spatial uncertainty regarding the trajectory of the ball was present and therefore only time judgements were required to catch the ball. RESULTS: The results of the present research showed that children with DS missed more balls than the children from the control group; the children with DS missed 30% of the balls vs. the children from the control group, who missed 7% of the balls. In addition, children with DS missed more small balls. The kinematic analysis of the time characteristics of one handed catching revealed that the difference in timing occurs at the time of grasping the ball. When examining the time of the catch in relationship to the time window, it can be seen that most children with DS tended to finish their catch too late. CONCLUSIONS: Since differences were not found for the time of initiation and the time of maximal aperture, the present experiment suggests that it is not so much the anticipatory control but a slowness of movement that causes the higher percentage of catching failures in the children with DS.[VÝCHODISKA: Chytání míče jednou rukou je dovednost s obtížnou koordinací.

Vežba srpskih i ruskih pilota BARS 2016, nametnula se kao osnovni zadatak nakon nabavke dva aviona MIG-29 i helikoptera MI-17. Ne samo radi upoznavanja letnih i borbenih osobenosti tih letelica, već i radi ovladavanja taktičkom upotrebom u složenim borbenim dejstvima. Nesumnjivo je da ruski piloti poseduju veoma dragoceno iskustvo u presretačkim dejstvima sa letelicom MIG-29, kao i u vazdušnoj borbi. Ovaj avion ima izuzetne letne mogućnosti i pod veštom pilotskom rukom može da izvede veoma složene manevre kojima se ostvaruje prevlast u vazdušnom prostoru i pobeda u vazdušnoj bici. Zbog toga se vežba ruskih i srpskih pilota BARS 2016 može posmatrati, a valja je prvenstveno i razumeti kao značajan napredak u ovladavanju osnovnim savremenim borbenim postupcima u obezbeđivanju vlastitog vazdušnog prostora, kontrole i suprotstavljanju agresivnim dejstvima eventualnog protivnika.

OBJECTIVE: The aims of this study were twofold: firstly to analyze moderate physical activity and walking within the leisure time, domestic, occupational and transport related domains of the inhabitants of the Czech Republic aged 55–69, and secondly, to investigate the socio-demographic and environmental factors which can influence meeting physical activity recommendations in leisure time, domestic, occupational and transport related domains. METHODS: The long version of the International Physical Activity Questionnaire (IPAQ was used to assess physical activity in 320 randomly selected inhabitants of the Czech Republic aged 55–69. They also answered additional questions on socio-demographic and environmental factors. RESULTS: Meeting moderate physical activity recommendations was significantly associated with elementary education, the age group 55–59 (compared to the age group 65–69, living in a house and non smoking whereas the likelihood of meeting the walking recommendation was connected only with having an occupation. Different socio-demographic and environmental factors were associated with moderate physical activity and walking within different domains.

Delší doba každodenního sezení rodičů je asociována (rS = 0,28–0,42; p < 0,006 s delší dobou sezení jejich dětí. Děti, dcery i synové, a jejich matky, které se dva a vícekrát týdně účastní organizované PA, vykazují signifikantně delší dobu provádění intenzivní PA (p < 0,02; eta2 > 0,05 než děti a jejich matky bez účasti v organizované PA. Na základě zjištěných vztahů mezi pohybovou aktivitou, sezením a účastí v organizované PA lze souhlasit s tvrzením, že "pohybově aktivnější rodiče vychovávají pohybově aktivnější děti" (zřetelněji u synů. A naopak "pohybově méně aktivní rodiče vychovávají pohybově méně aktivní děti" (zřetelněji u dcer. Účast v organizované PA se u dětí a matek příznivě podílí na celkově vyšší úrovni realizované PA, zvláště pak u intenzivní PA. Next to genetic predispositions, performance of physical activity (PA in children is influenced by a variety of variables including the parents' PA. The aim of this study is to describe

Po Olympijských hrách v roce 2000 bylo tradiční přeskokové nářadí nahrazeno moderním přeskokovým stolem. V současné době nejsou známy komplexní biomechanická data o přeskocích při použití nového přeskokového stolu a je otázkou, jaké je současné provedení přemetových přeskoků u vrcholových sportovních gymnastek. CÍLE: Cílem studie je určit, které biomechanické faktory se podílejí na úspěšném provedení přemetových skoků. METODIKA: Výzkumu se účastnilo osm vrcholových sportovních gymnastek. Pro 3D prostorovou analýzu byly použity dva digitální kamkordéry se snímkovací normou 50 půlsnímků/s. Data byla digitalizována pomocí softwaru Simi motion. Metoda podle Hay a Reid (1988 byla použita pro identifikaci biomechanických proměnných, které ovlivňují průběh přemetových skoků. Pro posouzení závislosti mezi biomechanickými proměnnými a bodovým hodnocením byla použita korelační analýza. Hladina statistické významnosti byla nastavena na hladinu p < 0,05. VÝSLEDKY: Z 23 vyšetřovaných proměnných byly u pěti zjištěny signifikantní korelace s bodovým hodnocením. Signifikantní korelace byla zjištěna u vertikální výšky těžiště těla při odrazu z přeskokového stolu (r = 0,86, maximální výšky těžiště těla ve druhé letové fázi (r = 0,83, změně horizontální rychlosti ve fázi odrazu z přeskokového stolu (r = -0,69, u horizontální složky rychlosti při odrazu z přeskokového nářadí (r = 0,75 a doby trvání druhé letové fáze (r = 0,69.

U ovom radu su opisane metode prikupljanja digitalnih dokaza u elektronskoj pošti i njihova analiza. Uvod Elektronska pošta se kao dokazni materijal pojavljuje u velikom broju kako građanskih tako i kriminalnih forenzičkih istraga. Elektronska pošta i elektronska pošta zasnovana na internet serverima  širi se veoma brzo, pa lako i brzo završi i na računaru korisnika kome nije namenjena. Prvu elektronsku poruku poslao je Ray Tomilson 1971. godine, a deset godina kasnije u kombinaciji sa personalnim računarima i internetom prerasta u globalni način komuniciranja i personalnog i poslovnog. Takođe se koristi i u svrhu zabave, načina razmene podataka, ali predstavlja i nezamenjiv izvor digitalnih dokaza, kada dodje do računarskog incidenta. Analiza elektronske pošte Svaka elektronska poruka sastoji se od dva dela: zaglavlja i teksta poruke. Iz zaglavlja je moguće saznati izvorišnu i odredišnu adresu, pošiljaoca i namenjenog primaoca, a telo poruke sadrži tekst poruke. Ekstenzije dokumenata elektronske pošte U slučajevima kada je potrebno otkriti samo dokumente potrebne za pregled elektronskih poruka, ili kopirati pojedinačni dokument sačuvan unutar elektronske pošte, moguće je koristiti sistem na istraživanom računaru ili specijalizovani softver kao što je Outlook Extract Pro ili Outlook Export. Mnogo ispravniji, sigurniji i jednostavniji način je korišćenje forenzičkih alata kao što su EnCase ili FTK, sa ugrađenim pregledačima koji omogućavaju pregled i snimanje sadržaja baze podataka kao i njihovo kopiranje na druge medije za dalju analizu. Forenzički alati automatizuju proces skidanja i kopiranja

    Full Text Available Low Back Pain (LBP is one of the most common incidences all over the world. For the assessment of LBP, descriptive medical scores are widely used. Nevertheless, there is a need for the quantitative assessment of LBP by appropriate physiological and kinematic measurements. Quantitative assessment methods are of interest since they might provide reliable and repeatable measures related to low back pain in both everyday clinical practice and at home or work. In this paper, we proposed simple measurements of the trunk angle and the activity of back muscles during simple flexion/relaxation task for an improved assessment of LBP (Low Back Pain. The application of the proposed instrumentation and signal processing is evaluated in three healthy subjects and in two individuals with LBP.The presented data analysis indicates that angle velocity might be a promising parameter in a combination with electromyography profiles for differentiation between healthy subjects and in individuals with LBP for improved medical diagnostics and assessment. / Bol u leđima je jedan od najčešćih zdravstvenih problema ljudi u celom svetu.

One mogu biti locirane unutar poznatog diskretnog skupa potencijalnih lokacija skladišta, pod uslovom da budu zadovoljena minimalna bezbednosna rastojanja između odabranih lokacija. Minimalno bezbednosno rastojanje je posledica postojanja verovatnoće da opasne materije neželjeno deluju na objekte u okolini. Cilj je da se istovremeno maksimizira uskladištena količina različitih opasnih materija, vodeći računa o minimalnim bezbednosnim rastojanjima. Za neke opasne materije minimalno bezbednosno rastojanje je konstantna vrednost, koja zavisi samo od karakteristika opasnih materija. Sa druge strane, minimalno bezbednosno rastojanje može da varira u zavisnosti od količine opasne materije i njenih ostalih karakteristika. Za ova dva tipa minimalnih bezbednosnih rastojanja predloženi su modeli mešovitog celobrojnog programiranja. Ovi modeli zasnovani su na lokacijskom problemu nepokrivanja, pa se mogu tretirati i kao njegova modifikacija i proširenje.

Rezultati simulacije pokazuju da na dinamičko ponašanje sistema utiču pritisak u vazdušnom jastuku, prečnik ventila, koeficijent prigušenja i mehanička krutost opruge. Metodologija poluaktivnog upravlјanja sistemom oslanjanja zasniva se na kontroli prečnika ventila korišćenjem dva stanja jednog on-off prekidača, na

Prvi rad autorice A. Gilliland pod naslovom Razvoj teorije, prakse i istraživanja o zaštiti i pristupu arhivskom gradivu u digitalnom svijetu bavi se izazovima koji su stavljeni pred nove generacije arhivista, knjižničara i mnogih drugih znanstvenika pojavom i naglim razvojem novih tehnologija i novih mogućnosti umnažanja i proizvodnje potencijalnog arhivskog gradiva. Postavlja se pitanje što sačuvati, koji su kriteriji selekcije elektroničkih dokumenata i njihovih inačica i sl. Autorica daje pregled promjena koje su se dogodile u arhivističkim istraživanjima, otvara pitanja novih područja kojima se bave arhivisti uzimajući u obzir, tj. stavljajući ih u odnos s tzv. tradicionalnim zadaćama arhivista. Autorica također pokazuje i ukazuje na dodirne točke arhivističkih i informacijskih/ knjižničarskih istraživanja u kontekstu bavljenja digitalnom građom i dokumentima. Autori drugoga rada D. Hasenay, M. Krtalić i I. Gobić Vitolović pod naslovom Zaštita i konzervacija starih knjiga bave se problemima zaštite na strateškoj razini, vrstama materijala stare građe, njihovim oštećenjima te metodama i postupcima zaštite i konzervacije oštećene građe i restauracije. U kontekstu novih tehnologija autori promatraju digitalizaciju kao jedan od postupaka zaštite stare građe. Posljednja cjelina pod naslovom Upravljanje zbirkama stare građe (Old book collection management sadrži opsežan rad autorice L. Miletić-Vejzović pod naslovom Upravljanje zbirkama posebne vrste građe s naglaskom na projekte digitalizacije. U svome radu autorica se bavi svim aspektima upravljanja jednom zbirkom

Sistem manipulacije  projektovan je tako da istovremeno rotiraju alat i substrati oko svoje ose. Ovako složeno kretanje omogućava ravnomerno čišćenje transferovanim lukom i ravnomerno deponovanje praha po celoj površini substrata. U ovom istraživanju su urađene tri grupe uzoraka sa tri odstojanja depozicije praha 270, 295 i 320 mm. Prevlake su formirane sa debljinama od 0,15 do 0,20 mm. Ostali parametri bili su konstantni. Prevlaka najboljih strukturnih i mehaničkih karakteristika je testirana na oksidaciju u peći za termičku obradu  bez  zaštitne atmosfere na 11000C u trajanju od 240 sati. Rezultati i diskusija Vrednosti mikrotvrdoće slojeva su u direktnoj vezi sa odstojanjem depozicije praha. Najveću vrednost mikrotvrdoće od 615 HV0.3 su imali slojevi sa najmanjim udelom pora koji su deponovani na  supstratu sa najmanjim plazma sprej odstojanjem  od 270mm. Slojevi prevlake deponovani sa najvećim odstojanjem od 320 mm imaju najnižu vrednost mikrotvrdoće od  490HV0.3. Veliko odstojanje supstrata je uticalo na pothlađenje i smanjenje brzine istopljenih čestica praha. Poređenjem vrednosti zatezne čvrstoće spoja, ustanovljeno je da su se za sva tri plazma sprej odstojanja dobile dobre vrednosti čvrstoće spoja. Čvrstoća spoja prevlaka je bitno zavisila od plazma sprej odstojanja. Niža vrednost zatezne čvrstoće spoja od 52MPa, prevlake deponovane sa najvećim plazma sprej odstojanjem od 320mm uticala je na manji stepen stapanja čestica praha u odnosu na druga dva deponovana sloja. Najveću vrednost čvrstoće spoja od 78MPa su imali slojevi, koji su deponovani sa najmanjim plazma sprej odstojanjem. Ti slojevi su se pokazali najgušćim. Ispitivanje zatezne čvrstoće spoja je pokazalo da se za sve deponovane prevlake mehanizam razaranja odvijao na interfejsu između substrata i prevlake. Pošto je udeo pora i neistopljenih

    rezultati su bili  usrednjeni. Testovi zatezne čvrstoće rađeni su na sobnoj temperaturi na hidrauličnoj opremi sa brzinom od 10 mm/min. Korišćena su dva uzoraka u paru, od kojih je prevlaka deponovana samo na jednom od njih. Za svaku grupu WC17Co prevlaka ispitano je po pet uzoraka, a dobijeni rezultati su usrednjeni. Metalografska procena udela pora (image analiza u slojevima WC17Co prevlaka urađena je tehnikom svetlosne mikroskopije u skladu sa standardom Pratt & Whitney (Turbojet Engine – Standard Practices Manual (PN 582005, 2002, Pratt & Whitney, East Hartford, USA. Morfologija čestica praha urađena je na SEM-u (skening elektronskom mikroskopu. Depozicija praha Proces deponovanja slojeva na metalne osnove urađen je plazma-sprej postupkom na atmosferskom pritisku (APS firme Plasmadyne. Depozicija praha urađena je plazma pištoljem SG-100 koji se sastojao od katode tipa K 1083A -129 , anode tipa A 2083-175 i gas-injektora tipa  GI 1083-113. Kao gas korišćen je argon u kombinaciji sa helijumom i snaga napajanja od 40 KW. Protok plazma gasa helijuma bio je osnovni parameter za deponovanje praha. U eksperimentu su korišćena tri različita protoka helijuma od 12 l/min, 22 l/min i 32 l/min. Slojevi su deponovani na supstratima ukupne debljine od 0,020 do 0,025 mm sa plazma pištoljem brzine 500 mm/s. Rezultati i diskusija Vrednosti mikrotvrdoće i čvrstoće spoja deponovanih slojeva su u direktnoj vezi sa protocima helijuma kao plazma gasa. Svi deponovani slojevi imaju vrednosti mikrotvrdoće u propisanim granicama od 850 do 1300 HV0.3 (Material Product Data Sheet, 2011, (Turbojet engine-standard practices manuel TURBOMECA.  Najravnomerniju raspodelu mikrotvrdoće imali su slojevi deponovani sa protokom plazma gasa od 22 l/min.He. Ti slojevi su imali najmanju razliku  mikrotvrdoće između maksimalnih i minimalnih vrednosti (289 HV0.3. Najveću raspodelu mikrotvrdoće pokazali su slojevi  deponovani sa najvećim protokom plazma gasa od 32 l/min He. Ti
