    2016-07-01

    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.

    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 reliability. RESULTS: The three age groups were not different in their height, weight and normal walking speed (p>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 (preliability. FarDVA at 0.8 m/s and 1.0 m/s demonstrated good test-retest reliability (ICCs 0.71 and 0.77, respectively).

    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.

    2014-01-01

    In this essay, we discuss words and images in sixteenth-century Venice in two forms: the prose commentary and woodcuts in Cesare Vecellio's Degli habiti antichi et moderni di diverse parti del mondo (Venice, 1590), and the paintings of Paulo Veronese from 1550 to 1578. Our theoretical framework is the analysis of ideology as it is materialized in the making, wearing and representation of clothing. We study three kinds of dress in Venice: the red silks worn by wealthy merchants, the black wool...

  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

    2014-07-01

    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.

    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.

    Directory of Open Access Journals (Sweden)

    Khoirul Huda

    2014-01-01

    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.

    This publication summarises the assessment results from the VTT Digitalo case. VTT Digitalo is a new office building built for the use of VTT research and development. The building was assessed from the viewpoints of sustainable construction and sustainable workspaces. The study analysed the case considering it as an achievement and a stage in a long-term process that is taking place between VTT as the user and Senate Properties as the owner of the building. This process aims at developing high-quality facility services, which are in accordance with the user needs, and based on understanding the strategic goals of the user. Additionally, these services should follow the principles of sustainable construction. The VTT's user needs concern first of all (a) good indoor environment in terms of indoor climate, acoustics and illumination, (b) ability of the workspace to support interaction and innovative way of working, (c) ability of the whole building to indicate VTT's image as a supplier of innovation services. VTT acts as a client, which sets performance and conformity requirements based on the planned use of spaces. The aims of Senate Properties as the owner and the provider of facility services concern the ability to understand and realise user needs, and to manage investment costs and life cycle efficiency of the building. The research defines sustainable construction in accordance with (ISO 2006): Sustainable construction brings about the required performance with the least unfavourable environmental impact, while encouraging economic, social, and cultural improvement at a local, regional, and global level. Accordingly, the study defined as a premise that a comprehensive analysis of the sustainability of an office building should be based on the assessment of the following aspects: user satisfaction, building performance and environmental impacts, and life cycle costs and life cycle economy.

    Full Text Available Purpose of the article: The article examines the IAS 1 revised that allows the company to choose between a reclassification of items by nature or by function (destination, it also provides two alternative presentations of the income statement: a single statement of comprehensive income or two statements, the first containing the components of net income, and the second that, starting from net income, shows the other components of expanded income. 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.

    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 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.

  19. Optimal design of a beam-based dynamic vibration absorber using fixed-points theory

    Science.gov (United States)

    Hua, Yingyu; Wong, Waion; Cheng, Li

    2018-05-01

    The addition of a dynamic vibration absorber (DVA) to a vibrating structure could provide an economic solution for vibration suppressions if the absorber is properly designed and located onto the structure. A common design of the DVA is a sprung mass because of its simple structure and low cost. However, the vibration suppression performance of this kind of DVA is limited by the ratio between the absorber mass and the mass of the primary structure. In this paper, a beam-based DVA (beam DVA) is proposed and optimized for minimizing the resonant vibration of a general structure. The vibration suppression performance of the proposed beam DVA depends on the mass ratio, the flexural rigidity and length of the beam. In comparison with the traditional sprung mass DVA, the proposed beam DVA shows more flexibility in vibration control design because it has more design parameters. With proper design, the beam DVA's vibration suppression capability can outperform that of the traditional DVA under the same mass constraint. The general approach is illustrated using a benchmark cantilever beam as an example. The receptance theory is introduced to model the compound system consisting of the host beam and the attached beam-based DVA. The model is validated through comparisons with the results from Abaqus as well as the Transfer Matrix method (TMM) method. Fixed-points theory is then employed to derive the analytical expressions for the optimum tuning ratio and damping ratio of the proposed beam absorber. A design guideline is then presented to choose the parameters of the beam absorber. Comparisons are finally presented between the beam absorber and the traditional DVA in terms of the vibration suppression effect. It is shown that the proposed beam absorber can outperform the traditional DVA by following this proposed guideline.

    2016-02-01

    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.

    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.)

    Full Text Available 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

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

    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

  3. A broadband frequency-tunable dynamic absorber for the vibration control of structures

    A passive-type dynamic vibration absorber (DVA) is basically a mass-spring system that suppresses the vibration of a structure at a particular frequency. Since the natural frequency of the DVA is usually tuned to a frequency of particular excitation, the DVA is especially effective when the excitation frequency is close to the natural frequency of the structure. Fixing the physical properties of the DVA limits the application to a narrowband, harmonically excited vibration problem. A frequency-tunable DVA that can modulate its stiffness provides adaptability to the vibration control device against non-stationary disturbances. In this paper, we suggest a broadband frequency-tunable DVA whose natural frequency can be extended by 300% to the nominal value using the magnetorheological elastomers (MREs). The frequency adjustability of the proposed absorber is first shown. The real-time vibration control performance of the frequency-tunable absorber for an acoustically excited plate having multiple resonant peaks is then evaluated. Investigations show that the vibration of the structure can be effectively reduced with an improved performance by the DVA in comparison to the conventional passive- type absorber. (paper)

    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

    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.

    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.

  19. 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 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.

    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.

    From March 1981 to January 1984, 116 patients with advanced non-small-cell carcinoma of the lung (NSCCL) were randomly assigned to 3 combinations as follow: CDDP+DVA, CDDP+VP16 and DXR+CTX. 94 patients were evaluable for response, 106 for toxicity and survival. Of 31 patients, 15 (48%; 3 CRs and 12 PRs) responded to CDDP+DVA; of 33 patients, 12 (36%, 2 CRs and 10 PRs) responded to CDDP+VP16: OF 30 patients, 3 (10%) obtained a PR with DXR+CTX (CDDP+DVA vs DXR+CTX, P<0.005; CDDP+VP16 vs DXR+CTX, P<0.05; CDDP+DVA vs CDDP+VP16, P=NS). The median duration of response was 22 weeks in the CDDP-DVA group, 17 weeks in the CDDP-VP16 group, and 16 weeks in the DXR+CTX group. No significant difference in survival was observed among the 3 groups (median: 43, 47, 41 weeks, respectively). Hematologic and neurologic toxicites were significantly higher in the DVA-containing regimen. Despite the lack of improvement of overall survival with the CDDP-containing combinations over the DXR+CTX control group, the good response rate makes them suitable to be used in combined therapeutic strategies

    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.

    Adequate function of the peripheral vestibular system, specifically the vestibulo-ocular reflex (VOR; a network of neural connections between the peripheral vestibular system and the extraocular muscles) is essential for maintaining stable vision during head movements. Decreased visual acuity resulting from an impaired peripheral vestibular system may impede balance and postural control and place an individual at risk of falling. Therefore, sensitive measures of the vestibular system are warranted to screen for the tendency to fall, alerting clinicians to recommend further risk of falling assessment and referral to a falling risk reduction program. Dynamic Visual Acuity (DVA) testing is a computerized VOR assessment method to evaluate the peripheral vestibular system during head movements; reduced visual acuity as documented with DVA testing may be sensitive to screen for falling risk. This study examined the sensitivity and specificity of the computerized DVA test with yaw plane head movements for identifying community-dwelling adults (58-78 years) who are prone to falling. A total of 16 older adults with a history of two or more unexplained falls in the previous twelve months and 16 age and gender matched controls without a history of falls in the previous twelve months participated. Computerized DVA with horizontal head movements at a fixed velocity of 120 deg/sec was measured and compared with the Dynamic Gait Index (DGI) a gold standard gait assessment measurement for identifying falling risk. Receiver operating characteristics (ROC) curve analysis and area under the ROC curve (AUC) were used to assess the sensitivity and specificity of the computerized DVA as a screening measure for falling risk as determined by the DGI. Results suggested a link between computerized DVA and the propensity to fall; DVA in the yaw plane was found to be a sensitive (92%) and accurate screening measure when using a cutoff logMAR value of >0.25.

    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.

    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.

    Full Text Available The article examines the relationships between literature and painting in the works of Rubén Darío. 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.

  16. Magnetic resonance angiography of cerebral developmental venous anomalies: its role in differential diagnosis

    1993-01-01

    CT, MRI and contrast angiography of 20 patients with 21 developmental venous anomalies (DVAs), so-called venous angiomas, were compared with magnetic resonance angiography employing a two-dimensional time-of-flight technique (2D-MRA). MRA was diagnostic in 17 DVAs, when both the primary 2D slices and the maximum-intensity-protection images were read. Contrast angiography still provides the best visualization of both DVA components: dilated medullary veins and transcerebral draining vein; however, it is an invasive procedure and delivers no information about brain parenchyma. We regard MRI as necessary in cases with a suspected DVA because of the high rate of association with cavernomas: 33% in this study. Acute neurological symptoms were caused by haemorrhage from an associated cavernoma and not from the DVA in 4 such cases. Thus MRA combined with MRI obviates angiography in most cases and offers a noninvasive diagnostic strategy adequate for DVAs. (orig.)

    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

  18. Effectiveness of off-the-shelf footwear in reducing foot pain in Australian Department of Veterans’ Affairs recipients not eligible for medical grade footwear: study protocol for a randomized controlled trial

    2013-01-01

    Background Foot pain is highly prevalent in older people, and in many cases is associated with wearing inadequate footwear. In Australia, the Department of Veterans’ Affairs (DVA) covers the costs of medical grade footwear for veterans who have severe foot deformity. However, there is a high demand for footwear by veterans with foot pain who do not meet this eligibility criterion. Therefore, this article describes the design of a randomized controlled trial to evaluate the effectiveness of low cost, off-the-shelf footwear in reducing foot pain in DVA recipients who are currently not eligible for medical grade footwear. Methods One hundred and twenty DVA clients with disabling foot pain residing in Melbourne, Australia, who are not eligible for medical grade footwear will be recruited from the DVA database, and will be randomly allocated to an intervention group or a ‘usual care’ control group. The intervention group will continue to receive their usual DVA-subsidized podiatry care in addition to being provided with low-cost, supportive footwear (Dr Comfort®, Vasyli Medical, Labrador, Queensland, Australia). The control group will also continue to receive DVA-subsidized podiatry care, but will not be provided with the footwear until the completion of the study. The primary outcome measure will be pain subscale on the Foot Health Status Questionnaire (FHSQ), measured at baseline and 4, 8, 12 and 16 weeks. Secondary outcome measures measured at baseline and 16 weeks will include the function subscale of the FHSQ, the Manchester Foot Pain and Disability Index, the number of DVA podiatry treatments required during the study period, general health-related quality of life (using the Short Form 12® Version 2.0), the number of falls experienced during the follow-up period, the Timed Up and Go test, the presence of hyperkeratotic lesions (corns and calluses), the number of participants using co-interventions to relieve foot pain, and participants’ perception of

    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

    The authors report a series of 16 patients with venous anomalies or abnormalities of the posterior fossa studied by angiography, CT and/or MRI. We believe that so-called 'venous angioma' are extreme anatomic variants that drain normal territories, and we prefer to call them developmental venous anomalies (DVA). Posterior fossa DVA, like the supra-tentorial ones are classified according to their drainage into deep and superficial type. They are exclusively located in the cerebellum or tectum. In 4 cases DVA was an incidental finding, in 3 an associated cerebral venous malformation (CVM) was found and felt to be the cause of the symptoms and only in one (Trigeminal pain) was a link between both suspected. Cavernous venous malformation (CVM) were found in frequent association with DVA (27%). 4 cases were single and 2 multiple. 5 CVM were located in the brain stem and 3 in the cerebellum. The clinical and radiological files were reviewed and a direct relationship between symptoms and localization was found in all patients with CVM. In 2 cases venous dysplasia was found: 1 Sturge-Weber and 1 First branchial arch syndrome. Both posterior fossa venous abnormalities were incidental findings. (orig.)

    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.

    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.

We measured static, kinetic, and dynamic visual acuity (SVA, KVA, and DVA, respectively of Japanese professional baseball players to ascertain whether there would be any difference in SVA, KVA, and DVA among player groups stratified according to their performance level. Methods: The subjects were 102 male professional baseball players with a mean age of 26 years who were members of a Japanese professional baseball club from 2000 to 2009. They were stratified into three groups according to their performance level: A (players who were on the roster of the top-level team all the time throughout the study period, B (players who were on the roster of the top-level team sometimes but not all the time, and C (players who were never on the roster of the top-level team. They were interviewed for the use of corrective visual aids, and examined for SVA, KVA, and DVA. The measurements of these parameters were compared among groups A, B, and C. We also investigated and analyzed the association of KVA or DVA with player position (pitchers or fielders and with hand dominance for batting. KVA was compared between the pitchers and the fielders because they each require different playing skills. DVA was compared between the right-handed and the left-handed batters. Results: There was no statistically significant difference among groups A, B, and C. There was a statistically significant difference in

    2016-01-01

    This article explores the challenges of providing a quantitative measure of domestic violence and abuse (DVA), illustrated by the Composite Abuse Scale, a validated multidimensional measure of frequency and severity of abuse, used worldwide for prevalence studies and intervention trials. Cognitive "think-aloud" and qualitative interviewing with a sample of women who had experienced DVA revealed a tendency toward underreporting their experience of abuse, particularly of coercive control, threatening behavior, restrictions to freedom, and sexual abuse. Underreporting was linked to inconsistency and uncertainty in item interpretation and response, fear of answering truthfully, and unwillingness to identify with certain forms of abuse. Suggestions are made for rewording or reconceptualizing items and the inclusion of a distress scale to measure the individual impact of abuse. The importance of including qualitative methods in questionnaire design and in the interpretation of quantitative findings is highlighted.

    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.)

Cross-sectional questionnaire-based study conducted between September 2010 and June 2011. 16 general practices in the south west of England. Male patients aged 18 or older, attending alone, who could read and write English. A total of 1403 of eligible patients (58%) participated in the survey and 1368 (56%) completed the questions relevant to this paper. 97% of respondents reported they were heterosexual. Lifetime occurrence of negative behaviour consistent with DVA, perceived health impact of negative behaviours, associations with anxiety and depression symptoms, and cannabis use in the past 12 months and binge drinking. 22.7% (95% CI 20.2% to 24.9%) of men reported ever experiencing negative behaviour (feeling frightened, physically hurt, forced sex, ask permission) from a partner. All negative behaviours were associated with a twofold to threefold increased odds of anxiety and depression symptoms in men experiencing or perpetrating negative behaviours or both. 34.9% (95% CI 28.7% to 41.7%) of men who reported experiencing negative behaviour from a partner, and 30.8% (95% CI 23.7% to 37.8%) of men who perpetrated negative behaviours said they had been in a domestically violent or abusive relationship. No associations with problematic drinking were found; there was a weak association with cannabis use. DVA is experienced or perpetrated by a large minority of men presenting to general practice, and these men were more likely to have current symptoms of depression and anxiety. Presentation of anxiety or depression to clinicians may be an indicator of male experience or perpetration of DVA victimisation. Published by the BMJ Publishing Group Limited.

    The vestibulo-ocular reflex (VOR) generates eye rotation to compensate for potential retinal slip in the specific plane of head movement. Dynamic visual acuity (DVA) has been utilized as a functional measure of the VOR. The purpose of this study was to examine changes in accuracy and reaction time when performing a DVA task with targets offset from the plane of rotation, e.g. offset vertically during horizontal rotation. Visual acuity was measured in 12 healthy subjects as they moved a hand-held joystick to indicate the orientation of a computer-generated Landolt C "as quickly and accurately as possible." Acuity thresholds were established with optotypes presented centrally on a wall-mounted LCD screen at 1.3 m distance, first without motion (static condition) and then while oscillating at 0.8 Hz (DVA, peak velocity 60 deg/s). The effect of target location was then measured during horizontal rotation with the optotypes randomly presented in one of nine different locations on the screen (offset up to 10 deg). The optotype size (logMar 0, 0.2 or 0.4, corresponding to Snellen range 20/20 to 20/50) and presentation duration (150, 300 and 450 ms) were counter-balanced across five trials, each utilizing horizontal rotation at 0.8 Hz. Dynamic acuity was reduced relative to static acuity in 7 of 12 subjects by one step size. During the random target trials, both accuracy and reaction time improved proportional to optotype size. Accuracy and reaction time also improved between 150 ms and 300 ms presentation durations. The main finding was that both accuracy and reaction time varied as a function of target location, with greater performance decrements when acquiring vertical targets. We conclude that dynamic visual acuity varies with target location, with acuity optimized for targets in the plane of motion. Both reaction time and accuracy are functionally relevant DVA parameters of VOR function.

  5. 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.

    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.)

    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.

    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.

  13. 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.

    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.)

  16. Agent Orange exposure and attributed health effects in Vietnam veterans.

    2011-07-01

    Serum dioxin studies of Vietnam (VN) veterans, military historical records of tactical herbicide use in Vietnam, and the compelling evidence of the photodegradation of 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) and other aspects of environmental fate and low bioavailability of TCDD are consistent with few, if any, ground troop veterans being exposed to Agent Orange. That conclusion, however, is contrary to the presumption by the Department of Veterans Affairs (DVA) that military service in Vietnam anytime from January 9, 1962 to May 7, 1975 is a proxy for exposure to Agent Orange. The DVA assumption is inconsistent with the scientific principles governing determinations of disease causation. The DVA has nonetheless awarded Agent Orange-related benefits and compensation to an increasing number of VN veterans based on the presumption of exposure and the published findings of the Institute of Medicine that there is sufficient evidence of a "statistical association" (a less stringent standard than "causal relationship") between exposure to tactical herbicides or TCDD and 15 different human diseases. A fairer and more valid approach for VN veterans would have been to enact a program of "Vietnam experience" benefits for those seriously ill, rather than benefits based on the dubious premise of injuries caused by Agent Orange.

    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.

    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.

    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 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. Pada rentang tersebut, daya bangkitan dan persentase reduksi perpindahan massa utama terbesar yang

    To evaluate whether computerized training with a crowded or uncrowded letter-discrimination task reduces visual impairment (VI) in 6- to 11-year-old children with infantile nystagmus (IN) who suffer from increased foveal crowding, reduced visual acuity, and reduced stereopsis. Thirty-six children with IN were included. Eighteen had idiopathic IN and 18 had oculocutaneous albinism. These children were divided in two training groups matched on age and diagnosis: a crowded training group (n = 18) and an uncrowded training group (n = 18). Training occurred two times per week during 5 weeks (3500 trials per training). Eleven age-matched children with normal vision were included to assess baseline differences in task performance and test-retest learning. Main outcome measures were task-specific performance, distance and near visual acuity (DVA and NVA), intensity and extent of (foveal) crowding at 5 m and 40 cm, and stereopsis. Training resulted in task-specific improvements. Both training groups also showed uncrowded and crowded DVA improvements (0.10 ± 0.02 and 0.11 ± 0.02 logMAR) and improved stereopsis (670 ± 249″). Crowded NVA improved only in the crowded training group (0.15 ± 0.02 logMAR), which was also the only group showing a reduction in near crowding intensity (0.08 ± 0.03 logMAR). Effects were not due to test-retest learning. Perceptual learning with or without distractors reduces the extent of crowding and improves visual acuity in children with IN. Training with distractors improves near vision more than training with single optotypes. Perceptual learning also transfers to DVA and NVA under uncrowded and crowded conditions and even stereopsis. Learning curves indicated that improvements may be larger after longer training.

    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.

  6. Experimental Studies on Dynamic Vibration Absorber using Shape Memory Alloy (NiTi) Springs

    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

  13. Directional variance adjustment: bias reduction in covariance matrices based on factor analysis with an application to portfolio optimization.

    Directory of Open Access Journals (Sweden)

    Daniel Bartz

    Full Text Available 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.

  17. Dynamic Visual Acuity and Landing Sickness in Crewmembers Returning from Long-Duration Spaceflight

    Science.gov (United States)

    Rosenberg, M.J.F; Peters, B.T.; Reschke, M. F.

    2016-01-01

    Long-term exposure to microgravity causes sensorimotor adaptations that result in functional deficits upon returning to a gravitational environment. At landing the vestibular system and the central nervous system, responsible for coordinating head and eye movements, are adapted to microgravity and must re-adapt to the gravitational environment. This re-adaptation causes decrements in gaze control and dynamic visual acuity, with astronauts reporting oscillopsia and blurred vision. Dynamic visual acuity (DVA) is assessed using an oscillating chair developed in the Neuroscience Laboratory at JSC. This chair is lightweight and easily portable for quick deployment in the field. The base of the chair is spring-loaded and allows for manual oscillation of the subject. Using a metronome, the chair is vertically oscillated plus or minus 2 cm at 2 Hz by an operator, to simulate walking. While the subject is being oscillated, they are asked to discern the direction of Landolt-C optotypes of varying sizes and record their direction using a gamepad. The visual acuity thresholds are determined using an algorithm that alters the size of the optotype based on the previous response of the subject using a forced-choice best parameter estimation that is able to rapidly converge on the threshold value. Visual acuity thresholds were determined both for static (seated) and dynamic (oscillating) conditions. Dynamic visual acuity is defined as the difference between the dynamic and static conditions. Dynamic visual acuity measures will be taken prior to flight (typically L-180, L-90, and L-60) and up to eight times after landing, including up to 3 times on R plus 0. Follow up measurements will be taken at R plus 1 (approximately 36 hours after landing). Long-duration International Space Station crewmembers will be tested once at the refueling stop in Europe and once again upon return to Johnson Space Center. In addition to DVA, subjective ratings of motion sickness will be recorded

    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'.

    Bertolak dari urgensi pelibatan pandangan masing-masing kelompok tentang the others dalam setiap inisiasi perdamaian, studi ini mengkaji (1 konstruksi sosial para elit kelompok-kelompok keagamaan di Kota Mataram tentang the others sekaligus menentukan (2 tipologinya berdasar tiga model utama keberagamaan, yakni eksklusivisme, inklusivisme, dan pluralisme. Para elit dipilih sebagai subjek karena mereka berperan signifikan dalam kelompok masing-masing. Dalam dinamika sosial masyarakat Muslim Kota Mataram, mereka kurang-lebih adalah ulama yang berperan sebagai “makelar budaya” sekaligus kreator aktif perubahan sosial. Untuk memahami konstruksi sosial para elit tentang the others, studi ini menerapkan teori konstruksi sosial Berger. 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.

    South Africa's first democratic government passed the Domestic Violence Act (DVA) into law in 1998 as part of local and international commitments to protecting the human rights of women. Although the Act was welcomed as groundbreaking legislation, delays in implementing it led to increasing frustration. This paper describes an advocacy campaign conducted by the Soul City Institute for Health and Development Communication in partnership with the National Network on Violence against Women, to ensure the effective implementation of the DVA. Lessons from the campaign stress the importance of coalition building to draw on diverse strengths, and the use of a combination of advocacy tools, including lobbying, media advocacy and social mobilisation to achieve campaign goals. Given the critical role NGOs dealing with victims/survivors of domestic violence and the justice system played in lobbying for change and drafting the new law, their exclusion from the implementation process was ironic. While many advocacy efforts focus on the development of policy and legislation, ongoing efforts are needed to ensure effective implementation, the commitment of adequate resources and monitoring to identify gaps and propose new solutions. Our experience highlights the important role of policy advocates in connecting the multiple streams at play in the policy and legislative arena.

    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. 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. 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. 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.

    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.

    Over the past three decades, a growing body of research has focused on experiences of domestic violence and abuse (DVA) among people of diverse genders and/or sexualities. Missing, however, has been a focus on what is known as "the link" between DVA and animal cruelty with regard to people of diverse genders and/or sexualities. The present article reports on a study of 503 people living in either Australia or the United Kingdom, who reported on both their intimate human relationships and their relationships with animals, including relationships that were abusive. In terms of "the link," a fifth of respondents who had experienced violence or abuse also reported that animal cruelty had been perpetuated by the violent or abusive partner. Statistical interactions were found between having witnessed animal cruelty perpetrated by a partner, gender and sexuality, and both psychological distress and social connectedness. Female participants who had witnessed animal cruelty reported greater psychological distress and lower levels of social support, and both lesbian and bisexual participants who had witnessed animal cruelty reported lower levels of social support. The article concludes by considering the implications of these findings for future research and service provision.

  12. Fund allocation within Australian dental care: an innovative approach to output based funding.

    2005-12-01

    Over the last 15 years in Australia the process of funding government health care has changed significantly. The development of dental funding models that transparently meet both the service delivery needs for data at the treatment level and policy makers' need for health condition data is critical to the continued integration of dentistry into the wider health system. This paper presents a model of fund allocation that provides a communication construct that addresses the needs of both policy makers and service providers. In this model, dental treatments (dental item numbers) have been grouped into eight broad dental health conditions. Within each dental health condition, a weighted average price is determined using the Department of Veterans Affairs' (DVA) fee schedule as the benchmark, adjusted for the mix of care. The model also adjusts for the efficiency differences between sectors providing government funded dental care. In summary, the price to be applied to a dental health condition category is determined by the weighted average DVA price adjusted by the sector efficiency. This model allows governments and dental service providers to develop funding agreements that both quantify and justify the treatment to be provided. Such a process facilitates the continued integration of dental care into the wider health system.

    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.

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

    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.

    Full Text Available La mobilità veicolare rappresenta senza dubbio l’attività che più di ogni altra caratterizza i moderni assetti urbani. Tale funzione, che ha contribuito a liberare il cittadino dai vincoli della prossimità funzionale ed ha modellato la metropoli contemporanea, si pone oggi come principale fattore entropico urbano. La mobilità veicolare rappresenta infatti la seconda causa di emissioni di gas serra nell’atmosfera, contribuisce all’incremento del riscaldamento globale e dell’alterazione del micro-clima urbano, produce un sensibile abbattimento dei livelli di qualità della vita urbana, etc.. Molte città stanno implementando azioni per arginare il traffico veicolare all’interno centro urbano attraverso iniziative di dissuasione, tassazione o uso responsabile del veicolo privato. Probabilmente quest’ultima via può rappresentare la scelta più idonea in quanto agisce non in maniera coercitiva sul cittadino ma lo induce ad adottare nuovi comportamenti di responsabilità e una nuova etica dello spostamento. Il car-sharing promuove l’uso condiviso del medesimo veicolo che viene utilizzato da più utenti, secondo le diverse necessità, senza che questi ne detengano il possesso. L’articolo descrive le caratteristiche di tale sistema, segnala alcuni esempi virtuosi ma rileva anche come in realtà urbane quale Napoli, ove la mobilità veicolare rappresenta un consistente e storico problema per il quotidiano funzionamento della città ed ove molti anni fa si erano avviate innovative sperimentazioni di mobilità condivisa con autovetture a propulsione elettrica, oggi si continua a sopravvivere alla congestione da traffico veicolare e non esiste ancora alcuna possibilità concreta di utilizzare il car-sharing.

    To compare the demographic, socioeconomic, and medical characteristics of patients who had a General Practitioner Management Plan (GPMP) with those for patients without GPMP. Cohort study of patients with chronic diseases during the time period 1 July 2006 to 30 June 2008 using the Australian Department of Veterans' Affairs (DVA) claims database. Of the 88 128 veterans with chronic diseases included in the study, 23 015 (26%) veterans had a GPMP and 11 089 (13%) had a Team Care Arrangement (TCA). Those with a GPMP had a higher number of comorbidities (P<0.001), and a higher use of services such as health assessment and medicine review (P<0.001) than did those without GPMP. Diabetes was associated with a significantly increased use of GPMP compared with all other chronic diseases except heart failure. GPMPs are used in a minority of patients with chronic diseases. Use is highest in people with diabetes.

    The current study examined the nature of deficits in emotion recognition from facial expressions in case LG, an individual with a rare form of developmental visual agnosia (DVA). LG presents with profoundly impaired recognition of facial expressions, yet the underlying nature of his deficit remains unknown. During typical face processing, normal sighted individuals extract information about expressed emotions from face regions with activity diagnostic for specific emotion categories. Given LG’s impairment, we sought to shed light on his emotion perception by examining if priming facial expressions with diagnostic emotional face components would facilitate his recognition of the emotion expressed by the face. LG and control participants matched isolated face components with components appearing in a subsequently presented full-face and then categorized the face’s emotion. Critically, the matched components were from regions which were diagnostic or non-diagnostic of the emotion portrayed by the full face. In experiment 1, when the full faces were briefly presented (150 ms), LG’s performance was strongly influenced by the diagnosticity of the components: His emotion recognition was boosted within normal limits when diagnostic components were used and was obliterated when non-diagnostic components were used. By contrast, in experiment 2, when the face-exposure duration was extended (2000 ms), the beneficial effect of the diagnostic matching was diminished as was the detrimental effect of the non-diagnostic matching. These data highlight the impact of diagnostic facial features in normal expression recognition and suggest that impaired emotion recognition in DVA results from deficient visual integration across diagnostic face components.

    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 La vitamina A desempeña un papel fundamental en el desarrollo de los tejidos y órganos gracias a su capacidad de promover la diferenciación celular y regular la apoptosis. 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.

  18. A prediction model of compressor with variable-geometry diffuser based on elliptic equation and partial least squares.

    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.

    In order to increase the flux and experimental potentials of the RA reactor, properties of the reactor operating in the forced regime have been inspected four times, twice with the spent fuel (core C), and twice with partly fresh fuel (cores E and F). Forced regime means power higher than nominal 6.5 MW. From the analyses of technology parameters during operation in the forced regime at power levels of 7 and 11 MW, state and behaviour of the components, efficiency of the biological protection and other parameters it was concluded that the reactor operation is possible at power levels of 10 MW during a whole year, and under certain conditions even longer operation at power levels up to 15 MW. This paper examines the reactor operation conditions in the forced regime and gives conclusions related to real increase of the experimental possibilities, isotope production and economic factors. Radi povecanja fluksa i eksperimentalnih mogucnosti reaktora RA, cetiri puta su proverene osobine reaktora u forsiranom rezimu, tj. na snagama vecim od nominalne (6,5 MW) i to dva puta sa istrosenim gorivom (jezgro C) i dva puta sa delimicno svezim (jezgra E i F). Iz analize tehnoloskih parametara u toku eksperimentalno rada reaktora u forsiranom rezimu na snagama od 7 do 11 MW, stanja i ponasanja opreme, efikasnosti bioloske zastite i ostalih parametara, zakljucuje se da je moguc permanentan rad reaktora tokom cele godine na snagama do 10 MW, a pod izvesnim uslovima i duzi rad na snagama do 15 MW. U radu su diskutovani uslovi rada reaktora u forsiranom rezimu i donose se zakljucci o realnom povecanju eksperimentalnih mogucnosti, proizvodnje radioizotopa i o ekonomskim faktorima (author)

    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 (models.

    Left ventricular (LV) function is dependent on load, intrinsic contractility and relaxation with a variable impact on specific mechanics. Strain (ε) imaging allows the assessment of cardiac function however the direct relationship between volume and strain is currently unknown. The aim of this study was to establish the impact of preload reduction through head-up tilt (HUT) testing on simultaneous left ventricular (LV) longitudinal and transverse function and their respective contribution to volume change. A focused transthoracic echocardiogram was performed on 10 healthy male participants (23 ± 3 years,) in the supine position and following 1 min and 5 min of HUT testing. Raw temporal longitudinal ε (Ls) and transverse ε (Ts) values were exported and divided into 5% increments across the cardiac cycle and corresponding LV volumes were traced at each 5% increment. This provided simultaneous LV longitudinal and transverse ε and volume-loops (deformation-volume analysis - DVA). There was a leftward- shift of the ε -volume loop from supine to 1 min and 5 min of HUT, ptransverse thickening from supine to 1min, which was further augmented at 5min (p=0.018). Preload reduction occurs within 1 minute of HUT but does not further reduce at 5 minutes. This decline is associated with a decrease in longitudinal ε and concomitant increase in transverse ε. Consequently, augmented transverse relaxation appears to be an important factor in the maintenance of LV filling in the setting of reduced preload. DVA provides information on the relative contribution of mechanics to a change in LV volume and may have a role in the assessment of clinical populations. © 2018 The authors.

La questione della sottorappresentazione politica delle donne è stata sinora affrontata prevalentemente in termini tecnico-legali (politiche di pari opportunità ed azione positiva, o di teoria politica (la dicotomia pubblico-maschile e privato-femminile come fondamento del contratto sessuale della politica. Mancano invece contributi che guardino ai partiti come organizzazioni largamente responsabili dei processi di selezione e promozione delle carriere politiche, dunque come luoghi di quotidiana produzione di pratiche e culture di genere, più o meno egualitarie o, viceversa, discriminatorie. Sulla base di tale vuoto di ricerca e riflessione, il presente articolo si propone di mettere in luce le pratiche e le culture di genere che emergono dai racconti di uomini e donne all'interno di due organizzazioni partitiche, una di destra e una di sinistra, situate nel contesto territoriale della provincia di Trento. La ricerca è stata condotta attraverso lo strumento dell'intervista semi-strutturata, coinvolgendo quattro donne e quattro uomini, divisi per coppie di età (un uomo ed una donna giovani ed un uomo ed una donna da lungo presenti nel partito, accostabili per quanto concerne ruolo e posizione nelle organizzazioni partitiche considerate.

    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

    Full Text Available Ideile lui Rousseau au avut un impact major asupra societăţii la sfârşitul sec. al XVIII-lea şi pe parcursul întregii perioade a sec. al XIX-lea. Aceste idei au imprimat un suflu modern cugetului său, fiind considerat şi un ideologist politic, o voce puternică a Revoluţiei Franceze şi un pioner al curentului romantic. 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.

Bagaimana mungkin seorang yang anti tasawuf   juga adalah seorang aktivis tasawuf ? Bagaimana posisi Ibn Taymiyyah seharusnya dipetakan?  Bagaimana pula sikapnya yang terlihat kontradiktif ini dapat dijelasakan? Dengan mengkaji karya-karyanya dan mempertimbangkan pengalaman hidup Ibn Taymiyyah yang ditelisik melalui perspektif psikosufistik penulis akan menjawab persoalan tersebut. Tulisan ini menyatakan bahwa kritikan dan penolakannya atas jenis tasawuf tertentu (nazharī-falsafī didasarkan kerancuan dalam pemaknaan istilah dan paradigma yang berbeda dari objek yang dikritiknya.

    The purpose of this report is to present separately for black and white patients with advanced glaucoma 7-year results of two alternative surgical intervention sequences. A randomized controlled trial. A total of 332 black patients (451 eyes), 249 white patients (325 eyes), and 10 patients of other races (13 eyes) participated. Potential follow-up ranged from 4 to 7 years. Eyes were randomly assigned to either an argon laser trabeculoplasty (ALT)-trabeculectomy-trabeculectomy (ATT) sequence or a trabeculectomy-ALT-trabeculectomy (TAT) sequence. The second and third interventions were offered after failure of the first and second interventions, respectively. Average percent of eyes with decrease of visual field (APDVF), average percent of eyes with decrease of visual acuity (APDVA), and average percent of eyes with decrease of vision (APDV) are the outcome measures. Decrease of visual field (DVF) is an increase from baseline of at least 4 points on a glaucoma visual field defect scale ranging from 0 to 20, decrease of visual acuity (DVA) is a decrease from baseline of at least 15 letters (3 lines), and decrease of vision (DV) is the occurrence of either DVF or DVA. The averages are of percent decreases observed at 6-month intervals from the first 6-month visit to the end of the specified observation period. In both black and white patients throughout 7-year follow-up, the mean decrease in intraocular pressure was greater in eyes assigned to TAT, and the cumulative probability of failure of the first intervention was greater in eyes assigned to ATT. In black patients, APDVF, APDVA, and APDV are less for the ATT sequence than for the TAT sequence throughout the 7 years. In white patients, APDVF also favors the ATT sequence but only for the first year, after which it favors the TAT sequence through the seventh year; APDVA also favors the ATT sequence, but the ATT-TAT difference progressively diminishes over 7 years; and APDV favors ATT over TAT initially, but after 4

    The possibility of increasing the neutron flux in the RA reactor was considered for a number of years. The possibilities of reactor reconstruction are not realistic and they should be disregarded. The possibility that remains is to achieve higher neutron flux by improving the fueling scheme and above all by introducing highly enriched fuel into the reactor core. Decision to purchase highly enriched fuel was quicker due to the fact that the 2% enriched uranium fuel is not fabricated any more. There are two procedures for exchanging the fuel in the reactor core: a) removal of partially spent 2% enriched fuel and formation of the core with fresh highly enriched fuel; b) gradually introducing the new fuel into the existing RA reactor core according to a special transfer regime. This report includes some comparative analyses of these two procedures from both economic point of view and the needs of users, as well as some technical conditions. These results are in favour of gradual introducing of new fuel into the reactor core. relevant direct savings amount to 3 000 000 dinars. Some of the most important advantages cannot be estimated in this way. This report does not cover the safety analyses results which are presented in a series of other papers.

    2016-01-01

    A novel dynamic vibration absorber (DVA) configuration is introduced for simultaneous vibration suppression and energy harvesting from oscillations typically exhibited by large-scale low-frequency engineering structures and structural components. The proposed configuration, termed energy harvesting-enabled tuned mass-damper-inerter (EH-TMDI) comprises a mass grounded via an in-series electromagnetic motor (energy harvester)-inerter layout, and attached to the primary structure through linear spring and damper in parallel connection. The governing equations of motion are derived and solved in the frequency domain, for the case of harmonically-excited primary structures, here modelled as damped single-degree- of-freedom (SDOF) systems. Comprehensive parametric analyses proved that by varying the mass amplification property of the grounded inerter, and by adjusting the stiffness and the damping coefficients using simple optimum tuning formulae, enhanced vibration suppression (in terms of primary structure peak displacement) and energy harvesting (in terms of relative velocity at the terminals of the energy harvester) may be achieved concurrently and at nearresonance frequencies, for a fixed attached mass. Hence, the proposed EH-TMDI allows for relaxing the trade-off between vibration control and energy harvesting purposes, and renders a dual-objective optimisation a practically-feasible, reliable task.

    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.

    Full Text Available Recently developed parameterizations for the sea spray aerosol source flux, encapsulating wave state, and its organic fraction were incorporated into the aerosol–climate model ECHAM-HAMMOZ to investigate the direct and indirect radiative effects of sea spray aerosol particles. Our simulated global sea salt emission of 805 Tg yr−1 (uncertainty range 378–1233 Tg yr−1 was much lower than typically found in previous studies. Modelled sea salt and sodium ion concentrations agreed relatively well with measurements in the smaller size ranges at Mace Head (annual normalized mean model bias −13% for particles with vacuum aerodynamic diameter Dva Da Da Da −2, in contrast to previous studies. This positive effect was ascribed to the tendency of sea salt aerosol to suppress both the in-cloud supersaturation and the formation of cloud condensation nuclei from sulfate. These effects can be accounted for only in models with sufficiently detailed aerosol microphysics and physics-based parameterizations of cloud activation. However, due to a strong negative direct effect, the simulated effective radiative forcing (total radiative effect was −0.2 W m−2. The simulated radiative effects of the primary marine organic emissions were small, with a direct effect of 0.03 W m−2 and an indirect effect of −0.07 W m−2.

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.

The alarmingly high rate of recurrence of ulcerations in diabetic foot requires a change in our approach to care and to the vernacular in the medical literature. With its high rates of morbidity and recurrence, care of the complex diabetic foot may be aptly comparable to many forms of cancer. Therefore, our efforts should be not only in rapid healing of open wounds but also in maximizing ulcer-free days for the patient in diabetic foot remission. One facet of the multidisciplinary approach in managing wounds is achieved by reducing peak plantar pressures by offloading the foot with various conservative and surgical techniques aimed at reducing areas of stress caused by ambulation and improper shoe gear. Evidence supports the use of total contact casts as the gold standard for offloading open wounds; however, other methods have gained popularity as well. Novel approaches in surgical techniques and advances in wearable technology appear to show promise in measuring and modulating dangerous pressure and inflammation to extend remission and improve quality of life for these most complex patients.

  12. FRPR-4 Is a G-Protein Coupled Neuropeptide Receptor That Regulates Behavioral Quiescence and Posture in Caenorhabditis elegans.

    Directory of Open Access Journals (Sweden)

    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.

    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.

    In the working environment at the RA reactor, the level of gamma radiation is measured continuously by the built-in stationary system. According to the needs, measurement are done in the reactor hall every day. The level of gamma radiation is measured separately in typical points when the reactor is operated at nominal power and during intervals between two operating campaigns. The level of neutron radiation is measured according to the needs by means of a mobile spherical neutron detector. These measurements are done in the reactor hall around the horizontal experimental channels. Measured values of neutron radiation are three times lower than the relevant levels of gamma radiation. [Serbo-Croat] Na reaktoru RA vrsi se stalna kontrola nivoa gama zracenja po tehnoloskim i radnim prostorijama, pomocu ugradjenog stacionarnog sistema. Svakodnevno se vrse merenja u reaktorskoj hali, prema ukazanim potrebama. Posebno se mere nivoi gamma zracenja u karakteristicnim tackama pri radu reaktora na nominalnoj snazi i u pauzama izmedju dva kampanje. Merenje nivoa neutronskog zracenja vrsi se diskontinualno pomocu mobilnog sfernog neutronskog dozimetra. Merenja se obavljaju u hali oko horizontalnih eksperimentalnih kanala. Izmerene vrednosti su u proseku tri puta manje od odgovarajucih nivoa gama zracenja.

    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.

    It was concluded that reactor the reactor operation is very dangerous for the reactor installation as well as safety of the staff under conditions of heavy water increased activity. Two fundamental arguments in favour of this conclusion are: insufficient possibility of reactor components inspection during maintenance and operation in the future period; difficulties in prevention of accidents that could occur is equally dangerous for the reactor facility and the environment. Cleaning and decontamination of the complete heavy water system is needed before the reactor operation starts in order to avoid possible failures or accidental events. [Serbo-Croat] Zakljuceno je da je eksploatacija reakora u uslovima postojece aktivnosti teskovodnog sistema veoma opasna po sam reaktor i po personal. Dva osnovna razloga u prilog ovog zakljucka su: nedovoljna mogucnost kontrole ispravnosti svih elemenata reaktora u toku remonta i ekspolatacije u predstojecem periodu; teskoca borbe sa udesima, koji bi se eventualno dogodili podjednako je opasna po instalaciju i okolinu. Pre no sto se nastavi sa daljom ekspolatacijom reaktora potrebno ciscenje, dekontaminacija sistema teske vode kako bi se izbegla moguca ostecenja ili akcidentalne situacije.

    Full Text Available L’abandon unilatéral du système de protection tarifaire en 1986 et la signature, en 1992, de l’Accord de libre-échange nord-américain ont profondément marqué l’économie mexicaine. Orientée vers l’exportation, tournée vers les États-Unis et le marché nord-américain, celle-ci s’est modernisée, au prix toutefois d’importantes restructurations. Le cas du secteur automobile est à cet égard exemplaire. L’article qui suit analyse les transformations dans ce secteur dans le District fédéral. L’auteure utilise les données des recensements et s’appuie sur les résultats d’une enquête menée auprès des entreprises. Il en ressort que, malgré certaines difficultés, les grandes et moyennes entreprises sont en condition de fournir directement les usines de montage lorsqu’elles sont en mesure de s’adapter et répondre à leurs exigences. Le texte met en évidence le cas de la micro-entreprise TIER 1 qui travaille pour Volkswagen. Cette entreprise a démontré sa capacité d’apprentissage technologique sans avoir reçu l’appui de cette compagnie.Starting in 1986 with the unilateral withdrawal from the protective tariff system, and reinforced in 1994 when the North American Free Trade Agreement (NAFTA came into force, the policy of reorienting the Mexican economy toward the outside world was accelerated, especially towards the US and North America. The automotive industry in particular has gone through significant transformations, both in terms of modernization and relocation. This paper discusses the changes that have been taking place in the automotive industry established in Mexico City based on existing statistic data from the Census and evidence collected from a survey of industry companies. This article makes the argument that in spite of many difficulties, not only large or medium-sized companies can be direct suppliers of automobile assembly plants, given that this is dependent upon the ability to respect

    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

    observasi dan wawancara dengan para aktivis organisasi ekstra kampus di Purwokerto. Kemudian, penulis melakukan analisis-reflektif dengan menggunakan data-data dari sumber utama dan data pustaka. Ideologi Islam memiliki peranan yang amat penting sebagai pedoman, nilai, keyakinan dan arah untuk menggerakkan kegiatan-kegiatan dakwah. Ideologi tersebut dalam operasionalisasinya terjadi fragmentasi yang mengarah pada fundamental, modernis, liberal, dan tradisional. Proses terjadinya ideologi dipengaruhi oleh beberapa faktor di antaranya: latar belakang sejarah organisasi, memiliki hubungan ideologis dengan organisasi kemasyarakatan, berkembangnya organisasi-organisasi Islam transnasional, tuntutan dan kebutuhan mahasiswa era modern, serta adanya media informasi yang semakin massif. Implikasi dari fragmentasi ideologi Islam berdampak pada ragamnya kegiatan-kegiatan yang dilakukan oleh mahasiswa muslim pasca reformasi. Mereka tidak hanya melakukan kegiatan keagamaan melalui mentoring saja seperti yang terjadi pada era Orde Baru, melainkan juga menghadirkan kegiatan-kegiatan yang mengarah pada perdebatan teologi Islam, politik mahasiswa,pemberdayaan masyarakat, kepedulian pada masalahmasalah kemanusiaan dan global, serta responsif terhadap perkembangan ilmu dan teknologi.Adanya fragmentasi ideologi tidak perlu disikapi secara negatif dan tidak bisa disatukan dalam satu warna. Tugas kita adalah bagaimana memelihara dan mengembangkan ideologi tersebut secara kritis-konstruktif

    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

Od tri zaustavljanja ciji je uzrok bila oprema, dva su bila zbog otkazivanja novih elektronskih cevi. Od dva zaustavljanja koja je izazvalo pogonsko osoblje, jedno je bilo usled nepazljivog ukljucivanja pomocnog potrosaca, a drugo je ucinio operator jer se cinilo da snaga reaktora naglo raste. Kracih prekida rada bilo je tri, usled najavljenog iskljucenja napona. Ukupna doza ozracivanja ljudstva bila je manja nego prethodnih godina. Nije bilo ni jednog akcidenta. Dekontaminirano je znatno manje povrsina nego ranijih godina, i sakupljeno manje otpada nego prethodnih godina, dok tecnih efluenata nije bilo.

    2001-09-01

    To compare in eyes of black and white patients the progression of glaucoma after failure of medical therapy and upon start of surgical intervention. Cohort study analysis of data from a randomized clinical trial. This multicenter study included open-angle glaucoma patients who had failed medical therapy: 451 eyes of 332 black patients, 325 eyes of 249 white patients. Eyes were randomly assigned to an argon laser trabeculoplasty (ALT)-trabeculectomy-trabeculectomy (ATT) sequence or a trabeculectomy-ALT-trabeculectomy (TAT) sequence; they had been followed for 7 to 11 years at database closure. Main outcome measures were decrease of visual field (DVF), sustained decrease of visual field (SDVF), decrease of visual acuity (DVA), sustained decrease of visual acuity (SDVA), and failure of first surgical glaucoma intervention. Statistical methods included logistic regression to obtain average adjusted black-white odds ratios for binary outcomes, and Cox regression to estimate adjusted black-white risk ratios for time-to-event outcomes. In the ATT sequence blacks were at lower risk than whites of failure of first intervention (ALT, RR = 0.68, P = 0.040). In the TAT sequence blacks were at higher risk than whites of failure of the first intervention (trabeculectomy, RR = 1.79, P = 0.033), of intraocular pressure > or =18 mm Hg (average OR = 1.41, P = 0.026), and of DVF (average OR = 1.78, P = 0.007). In both treatment sequences, the average number of prescribed medications was greater for blacks than whites (P < or = 0.002). The results support the hypothesis that after failure of medical therapy and upon initiation of surgical intervention, an initial intervention with trabeculectomy retards the progression of glaucoma more effectively in white than in black patients. The data provide a weak suggestion that an initial surgical intervention with ALT retards the progression of glaucoma more effectively in black than in white patients.

  15. Analysis of the Relevance of Information Content of the Value Added Statement in the Brazilian Capital Markets

    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

    Full Text Available Abstract Background Peripheral vestibular hypofunction is a major cause of dizziness. When complicated with postural imbalance, this condition can lead to an increased incidence of falls. In traditional clinical practice, gaze stabilization exercise is commonly used to rehabilitate patients. In this study, we established a computer-aided vestibular rehabilitation system by coupling infrared LEDs to an infrared receiver. This system enabled the subjects’ head-turning actions to be quantified, and the training was performed using vestibular exercise combined with computer games and interactive video games that simulate daily life activities. Methods Three unilateral and one bilateral vestibular hypofunction patients volunteered to participate in this study. The participants received 30 minutes of computer-aided vestibular rehabilitation training 2 days per week for 6 weeks. Pre-training and post-training assessments were completed, and a follow-up assessment was completed 1 month after the end of the training period. Results After 6 weeks of training, significant improvements in balance and dynamic visual acuity (DVA were observed in the four participants. Self-reports of dizziness, anxiety and depressed mood all decreased significantly. Significant improvements in self-confidence and physical performance were also observed. The effectiveness of this training was maintained for at least 1 month after the end of the training period. Conclusion Real-time monitoring of training performance can be achieved using this rehabilitation platform. Patients demonstrated a reduction in dizziness symptoms after 6 weeks of training with this short-term interactive game approach. This treatment paradigm also improved the patients’ balance function. This system could provide a convenient, safe and affordable treatment option for clinical practitioners.

This system enabled the subjects' head-turning actions to be quantified, and the training was performed using vestibular exercise combined with computer games and interactive video games that simulate daily life activities. Three unilateral and one bilateral vestibular hypofunction patients volunteered to participate in this study. The participants received 30 minutes of computer-aided vestibular rehabilitation training 2 days per week for 6 weeks. Pre-training and post-training assessments were completed, and a follow-up assessment was completed 1 month after the end of the training period. After 6 weeks of training, significant improvements in balance and dynamic visual acuity (DVA) were observed in the four participants. Self-reports of dizziness, anxiety and depressed mood all decreased significantly. Significant improvements in self-confidence and physical performance were also observed. The effectiveness of this training was maintained for at least 1 month after the end of the training period. Real-time monitoring of training performance can be achieved using this rehabilitation platform. Patients demonstrated a reduction in dizziness symptoms after 6 weeks of training with this short-term interactive game approach. This treatment paradigm also improved the patients' balance function. This system could provide a convenient, safe and affordable treatment option for clinical practitioners.

    Full Text Available Ekološki pokreti u svetu su sve aktivniji, zbog stvarne ugroženosti Zemlje Mnogobrojni su oblici i izvori zagađenja, a jedan od najvećih su motori sa unutrašnjim sagorevanjem, za koje se pretpostavlja da će još dugo dominirati kao pogonski agregati u mnogim oblastima primene. 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.

Interrupted time-series analysis using the Department of Veterans' Affairs (DVA) claims dataset from 1 January 2002 to 31 August 2010. We examined the use of antithrombotics in people with atrial fibrillation and in those who had had a stroke, and the use of echocardiography and spironolactone in the population with heart failure. All veterans and their dependants in Australia who had received cardiovascular medicines or health services related to the targeted intervention. NPS MedicineWise national programs to improve cardiovascular management in primary care, which included prescriber feedback, academic detailing, case studies and audits as well as printed educational materials. Changes in medication and health service use before and after the interventions. All national programs were positively associated with significant improvements in related prescribing or test request practice. The interventions to improve the use of antithrombotics resulted in a 1.27% (95% CI, 1.26%-1.28%) and 0.63% (95% CI, 0.62%-0.64%) relative increase in the use of aspirin or warfarin in the population with atrial fibrillation 6 and 12 months after the program, respectively, and in a 1.51% (95% CI, 1.49%-1.53%) relative increase in the use of aspirin as monotherapy for secondary stroke prevention 12 months after the intervention. The heart failure programs resulted in a 3.69% (95% CI, 3.67%-3.71%) relative increase in the use of low-dose spironolactone and a 4.31% (95% CI, 4.27%-4.35%) relative increase in the use of echocardiogram tests 12 months after the intervention. NPS MedicineWise programs were effective in achieving positive changes in medicine and health service use for patients with cardiovascular diseases.

    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.

    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.

Devido a esses fatores, muitos têm sido os esforços pela sobrevivência no mercado a qual estão inseridas. Como forma de sobrevivência, muitas têm procurado atingir um melhor desempenho global, especialmente no que se refere à qualidade, custo e flexibilidade, procurando dessa forma obter uma vantagem competitiva em relação aos concorrentes e conseqüentemente tornar-se atraente para os consumidores. Assim diversas são as formas de se mensurar o desempenho das entidades. Os caminhos a serem seguidos podem ser de ordem financeira, econômica ou social, não sendo mutuamente excludentes, muito pelo contrário, se complementam na busca de uma maior evidenciação do desempenho gerencial. Neste sentido, temos a Demonstração do Valor Adicionado, que é um importante componente do Balanço Social, pois tem como principal objetivo evidenciar a capacidade da entidade de gerar riqueza bem como a forma de como esta é distribuída para os vários agentes sociais que contribuíram para a sua formação. À medida que uma entidade desenvolve suas atividades empresariais, produz fluxos de natureza econômica, apropriados mediante a confrontação das receitas com as despesas para determinar sua magnitude econômica, ou seja, o excedente produzido durante o período. Tradicionalmente, o resultado contábil (lucro líquido tem sido considerado um dos melhores indicadores para avaliar a gestão. No entanto, esse resultado não significa, fielmente, aumento de riqueza, porque evidencia a riqueza patrimonial sob a perspectiva dos proprietários ou acionistas.

    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.

    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

Foram realizados testes da função respiratória, incluindo espirometria, oscilometria de impulso e estudo da Capacidade de difusão alvéolo-capilar pelo CO. Os resultados foram comparados com os de outra população de igual número de mulheres, do mesmo grupo etário, consideradas normais no aspecto respiratório, com cargos administrativos, não sujeitas a agressão acústica detectável. Realizou-se um estudo estatístico dos resultados obtidos comparando as duas populações, tendo sido calculado para cada um dos parâmetros, escolhidos a partir do estudo funcional respiratório, os valores médios, o desvio-padrão e o grau de significância (pVibroacoustic disease is a pathology caused by long occupational exposure to large pressure amplitude and low frequency noise. It is a systemic disease, with evolvement of respiratory structures. The exposure workers to this noise of textile industry may favour alterations in lung function. We studied 28 women working more than ten years in cotton-mill rooms to evaluate their lung function, including Spirometry, forced oscillation technique (I.O.S. and Diffusion capacity. These results were compared with those of 30 women of similar ages not exposed to similar noise and not presenting respiratory disease. Statistical significance (p <0.05 was found with FEV25, R5 and D Rs5-Rs20. There was a resistance frequency dependence in 36% of the population exposed to noise, not statistically confirmed. Neither restriction nor changes in diffusing capacity where detected. Conclusion: The analysis of global alterations of lung function parameters suggests small airways aggression by noise.

    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 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.

    years of operation as well as purification of heavy water. [Serbo-Croat] Reaktor RA je u 1969. godini radio na nominalnoj snazi 200 dana i 15 dana na manjim snagama. Ukupni rad iznosio je 31131 MWh odnosno 3.77% vise od planiranog. Reaktor je koriscen za ozracivanja i eksperimenta prema zahtevima 463 korisnika iz Instituta i 63 izvan Instituta. Ovaj izvestak sadrzi detaljne podatke o snazi na kojoj je reaktor radio tokom 1969. godine i o uradjenim eksperimentima. Zakljuceno je da je reaktor RA uspesno radio prema planu rada. Da nije bilo problema sa napajanjem elektricnom energijom tokom poslednja tri meseca i niskog vodostaja Dunava u septembru i oktobru protekle godine bila bi to najuspesnija godina od pustanja reaktora u pogon. Broj sigurnosnih zaustavljanja nije bio veci u odnosu na prethodne dve godine i pored poteskoca u poslednjem kvartalu. Osoblje je bilo izlozeno povecanim dozama zracenja usled tri incidenta. Jedan je bio raspadanje kenera sa srebrom (zbog duzeg stajanja u aktivnoj zoni), sto je uzrokovalo kontaminaciju radne platforme, tako da je fon porastao za 10 do 100 puta od normalnohg Druga dva slucaja su bila otkazivanje uredjaja za mesanje goriva u tehnoloskim kanalima. Zamena goriva je radjena cetiri puta u toku godine, utroseno je 499 svezih gorivnih elemenata. Primenjena je metoda mesanja svezih gorivnih elemenata sa koriscenim gorivnim elementima u gorivnom kanalu. Dekontaminacija povrsina bila je na nivou prethodnih godina i pored problema sa srebrom. Kako su sa reaktora tokom godine otisla dva saradnika sa visokom spremom broj ljudi je opao na neophodan minimum za pogon i odrzavanje reaktora. Navrsavajuci u ovoj godini deset godina rada moze se reci da su rad i stanje opreme na tehnicki solidnom nivou. Kako bi se posle deset godina rada izvrsila kontrola vaznih komponenti reaktora i obavila rekoncentracija teske vode, za 1970. godinu je planirano da se proizvodnja smanji na 25000 MWh, a baziran je na istim principima kao i planovi za prethodne

    2012-10-01

    , 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

  9. La difficile constitution du corps enseignant équatorien: 1895-1946

    Directory of Open Access Journals (Sweden)

    2000-01-01

    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.

    A central objective of the Carbonaceous Aerosol and Radiative Effects Study (CARES) was to characterize unequivocally all aspects related to organics in aerosols. To this end, a range of instruments measured loadings, size distributions, compositions, densities, CCN activities, and optical properties of aerosol sampled in Sacramento, CA over the month of June 2010. We present the results of measurements conducted by our single particle mass spectrometer, SPLAT. SPLAT was used to measure the size, composition, and density of individual particles with diameters between 50 to 2000 nm. SPLAT measured the vacuum aerodynamic diameters (dva) of more than 2 million particles and the compositions of ~350,000 particles, each day. In addition, SPLAT was used in combination with a differential mobility analyzer to measure the density, or effective density of individual particles. These measurements were typically conducted twice per day: in the morning, and mid-afternoon. Preliminary analysis of the data shows that under most conditions, the particles were relatively small (below 200 nm), and the vast majority of them were composed of oxygenated organics mixed with various amounts of sulfates. Analysis of the mass spectra shows that the oxygenated organics in these particles are the oxidized products of biogenic volatile organic precursors. In addition to particles composed of SOA mixed with sulfates, we detected and characterized fresh and processed soot particles, biomass burning aerosol, organic amines, sea salt - fresh and processed - and a small number of dust and other inorganic particles, commonly found in urban environment. SOA mixed with sulfates were the vast majority of particles at all times, while the other particle types exhibited episodic behavior. The data shows a reproducible diurnal pattern in SOA size distributions, number concentrations, and compositions. Early in the morning the particle number concentrations are relatively low, and the particle size

These are (in alphabetical order the premier leagues in the Austrian, Czech, Hungarian, and Ukrainian soccer/football divisions. Static balance shows how teams in the league tables of each year differ from each another. It is determined by a calculation of determinant divergences in the percentages of winnings. The results of this work provide graphic illustrations of the development of the competitive balance in the aforementioned contests over the latest forty-two years. They identify the development trend of this phenomenon. Of the contests studied, it is the Czech premier league which used to show the highest static balance. However, nowadays, the Austrian and Hungarian leagues are more balanced in the short term. On the contrary, it is the Ukrainian league which is the least balanced. There is an apparent longterm decline of competition balance within all of the analyzed competitions. However, this decline varies a lot within the group.

Do ovog podatka moze se doci samo putem normalnog rada reaktora u toku vremena znatno duzeg od vremena u kome se uspostavlja ravnotezno zatrovanje, kao vremena izmedju dva prelivanja D{sub 2}O kondenzata u aktivnu zonu RA. U tom smislu je planirana desetodnevna eksperimentalna kampanja u decembru 1976. U ovom izvestaju izlozeni su oni najznacajniji rezultati sigurnosnih analiza i priprema koji ukazuju na potpunu sigurnost rada reaktora tokom ove eksperimentalne kampanje, sa aspekta postovanja ogranicenja najvaznijih parametara koji uticu na sigurnost reaktora, kao sto su reaktivnost, toplotna i temperaturska ogranicenja za gorivo i za reaktor, itd. Podaci koji budu dobijeni iz ove eksperimentalne kampanje su od znacaja jer ce se na osnovu njih konacno definisati dalji protok svezeg novog goriva, tokom prelaznog rezima (author)

    Full Text Available U Muzeju primijenjenih umjetnosti (Iparművészeti Múzeum u Budimpešti čuva se vezeni gotički antependij podrijetlom iz crkve benediktinskog samostana Sv. Krševana u Zadru. Antependij je u nepoznato vrijeme postao dijelom zbirke biskupa, povjesničara umjetnosti i kolekcionara Zsigmunda Bubicsa (biskup u Košicama u današnjoj Slovačkoj od 1887. do 1906. godine a u Muzeju primijenjenih umjetnosti je od 1909. godine. Dimenzije mu iznose 94 x 190 centimetara. Najveću površinu antependija zauzimaju svetački likovi pod trima zašiljenim gotičkim lukovima. U središnjem polju prikazana je Bogorodica s Djetetom na prijestolju, s lijeve strane je Sv. Krševan, a s desne Sv. Benedikt. U gornjem su dijelu dva dopojasno prikazana sveca koji bi se mogli identificirati kao Sv. Grgur Papa i Sv. Donat. ''Triptih'' sa svecima s lijeve je i desne strane flankiran bordurama u čijem su središnjem dijelu umetnute niše s dvama manjim stojećim likovima okrunjenih svetica (Sv. Katarina Aleksandrijska i Sv. Margareta. Lik donatora koji kleči s rukama sklopljenim u molitvi s lijeve strane Bogorodičina prijestolja nažalost nije popraćen nikakvim natpisom, no sasvim je jasno da je odjeven u benediktinski habit, s ponešto prenaglašenom kapuljačom koja mu pada preko leđa. Identitet benediktinca-donatora mogao bi se prepoznati u nekome od opata samostana Sv. Krševana. Pomišlja se da bi mogla biti riječ o Ivanu de Ontiacu (Joannes de Onciache iz lionske biskupije, koji je bio opatom samostana Sv. Krševana od 1345. do 1377. godine. Argumentira se da je antependij nastao u nekoj od venecijanskih vezilačkih radionica i to krajem šestog odnosno početkom sedmog desetljeća XIV. stoljeća, a na temelju usporedbi sa onovremenim slikarskim djelima te proizvodima umjetničkog (vezilačkog, tkalačkog i zlatarskog obrta. Na temelju zastupljenoga ikonografskog programa te podataka poznatih iz arhivskih izvora, pretpostavlja se da je antependij izrađen za

  15. Purists, Partisans, and the Aesthetic Dimension of Sport

    Full Text Available Purists, Partisans, and the Aesthetic Dimension of Sport Stephen Mumford, in his book Watching Sport, identifies two types of sports spectator – partisans and purists. Partisans are more concerned to see their team win, whether they do so in an aesthetically pleasing way or not, while purists have no such irrational commitment, and instead pursues the higher aesthetic experience of sport. The purist, Mumford argues, is superior because she watches sport for aesthetic and intellectual reasons and sees the game, it seems, more objectively, whereas the partisan is emotional and victoryseeking, experiencing the game through the lens of their desire for victory. But this distinction, I argue, doesn’t do justice to the actual experience of spectators. Whilst Mumford is correct to suggest that the aesthetic dimension is vital in our enjoyment of sport, there is no reason to suppose that the partisan cannot partake in the aesthetic appreciation of sport. Furthermore, whilst winning is obviously hugely important in judging the quality of sports teams, they are likely to be more fondly regarded if they do so through the demonstration of virtues that are aesthetic in nature. Even the most vociferous of partisans are capable of appreciating such teams. Puristé, partyzáni a estetická dimenze sportu Ve své knize Watching Sport Stephen Mumford identifikuje dva typy sportovních diváků – partyzány a puristy. Partyzáni se zajímají spíše o výhru svého týmu, ať už je jejich hra estetická, nebo ne, zatímco puristé nemají tento iracionální zájem a zajímá je vyšší estetický sportovní zážitek. Mumford považuje puristy za nadřazenější, protože sledují sport z estetických a intelektuálních důvodů, a zdá se, že vidí hru objektivněji, zatímco partyzáni jsou emocionální a sledují hru skrze touhu po vítězství. Moje argumenty ukazují, že toto pojetí adekvátně nepopisuje zážitek diváků. Zatímco Mumford

Aprila i septembra, integralna doza bila je veca nego u ostalim mesecima zbog akcidenta pri radu na izmeni goriva. Nije bilo znacajnijih kontaminacija povrsina pa su dekontaminirane povrsine izrazito male. U 1968, godini izradjen je uredjaj za mesanje goriva (stari i svezi gorivni elementi). Zahvaljujuci mesanju goriva postignuto je preko 50% bolje iskoriscenje goriva u odnosu na prethodni period. Prosecni zaposlenih broj ljudi bio je za 7 manji od preosecnog broja u prosloj godini. Plan rada za 1969. godinu bazira se na proizvodnji od 30 000 MWh a napravljen je na istim principima kao za prethodne tri godine.

    zahvat, koji se odnosi na zamenu celokupne instrumentacije je u toku, ali njegova realizacija u 1991. godini kasni zbog zastoja u isporuci opreme koja se izradjuje u Sovjetskom savezu. Izradu ove opreme finansira Medjunarodna agencija za atomsku energiju kroz ugovor sklopljen decembra 1988. godine sa moskovskom firmom Atomenergoexport. Prema tom ugovoru trebalo je da celokupna nova instrumentacija za reaktor RA bude isporucena Institutu u Vinci do kraja 1990. godine, ali je do septembra 1991. godine isporuceno svega 56% od predvidjene kolicine. Od tada je svaka isporuka obustavljena, a razlog je privremena zabrana na sve isporuke opreme za Jugoslaviju izrecena od strane ove organizacije Ujedinjenih nacija. U 1991. godini na reaktoru RA je demontirana postojeca instrumentacija u maksimalno mogucem obimu, kako bi se zadrzala neka osnovna merenja neophodna i u uslovima kada reaktor nije u pogonu. Pri kraju je izrada odredjenih konstrukcionih elemenata za novu instrumentaciju, koju je prihvatio da realizuje Institut u Vinci, kako bi se ubrzala realizacija ovog projekta. Ako sva predvijena oprema ne bude isporucena do kraja marta 1992. godine, nece moci da se otpocne sa probnim radom reaktora u prvoj polovini 1993. godine, kako je planirano. Na realizaciji projekta u 1991. godini ucestvovalo je efektivno 53 radnika, sto je dovoljan broj u uslovima remontnih i investicionih radova. Godisnji izvestaj o radu nuklearnog reaktora RA za 1992. godinu sastoji se od dva dela: prvi deo obuhvata pogon i odzavanje reaktora RA, a drugi poslove zastite od zracenja na reaktoru RA.

    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

    Full Text Available Godina 2017. u svjetskim je razmjerima bila iznimno dinamična godina. Obilježila su je različita zbivanja koja u našem globalnom selu imaju posvemašnji utjecaj bilo da je riječ o prirodnim katastrofama (uragani, požari, poplave i potresi ili onima na koje je znatno više utjecaja imala ljudska ruka, od terorističkih samoubilačkih napada, nuklearnog mahnitanja sjevernokorejskog vođe Kim Jong Una, neobičnog predsjednikovanja Donalda Trumpa ili, ako pogledamo bliže našem dvorištu, migrantskih valova, pokretanja postupka britanskog izlaska iz Europske unije te pokušaja katalonske vlade da izbori neovisnost od Španjolske. Istodobno tu su godinu u Hrvatskoj obilježile duboke društvene podjele, ideološke svađe te iseljavanje znatnog broja građana. Nezadovoljstvo koje hrvatski građani osjećaju i izražavaju prema stanju u državi, funkcioniranju njezinih institucija i pravcu u kojem zemlja ide daje nam pravo, ali nas i obvezuje, svakog pojedinačno i društvo u cjelini, upitati se što smo učinili u proteklih nemalih dva i pol desetljeća, odnosno jesmo li učinili dovoljno kako bismo opravdali stečenu neovisnost o kojoj su brojne generacije prije nas sanjale. Upravo je protek čak četvrt stoljeća od stjecanja neovisnosti bio poticaj prof.

    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

Na reaktoru RA uspesno su izvrseni eksperimentalni i teorijski radovi u oblasti sigurnosnih analiza za prevodjenje reaktora RA na novo 80% obogaceno gorivo, krunisani eksperimentalnom kampanjom reaktora RA u decembru 1976, kojom se zavrsava 17-to godisnji period koriscenja 2% obogacenog goriva i otpocinje period koriscenja novog 80% obogacenog goriva u reaktoru RA. Ovaj uspeh je od izuzetnog znacaja za reaktor RA i njegove korisnike, jer ce rezultovati u povecanju osnovne proizvodnje neutronskog fluksa od 50%, pri porastu cene kostanja rada reaktora od oko 4%. Podnet je zahtev za konacno odobrenje prelaznog rezima za uvodjenje ovog goriva, kojim se postize usteda od najmanje 2 200 000 dinara. Ovim se obezbedjuje da u 1977. godini i dalje, rad reaktora ne bude vise ometan ''kriticnim'' ili drugim eksperimentima u vezi sa uvodjenjem novog goriva u reaktor. Izvrsen je obiman program remontnih i drugih radova veoma akutne prirode, koji takodje omogucuju nesmetan rad u 1977. godini. Neki od ovih radova nisu radjeni nikad ranije, a drugi nisu radjeni u proteklih 6 godina. Najzacajniji zahvati ove vrste bili su: nabavka Al-cevi od specijalne legure, izrada i montiranje tehnoloskoh kanala; obimno ispitivanje uzroka curenja spoljasnjeg suda; remont teskovodne pumpe; zamena dva vertikalna tehnoloska kanala. Nabavljena je osnovna oprema za izgradnju sistema za hladjenje u slucaju udesa. Izvrseno je opremanje vrucih komora reaktora RA.

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

    Full Text Available Vibroacoustic disease is a pathology caused by long occupational exposure to large pressure amplitude and low frequency noise. It is a systemic disease, with evolvement of respiratory structures. The exposure workers to this noise of textile industry may favour alterations in lung function. We studied 28 women working more than ten years in cotton-mill rooms to evaluate their lung function, including Spirometry, forced oscillation technique (I.O.S. and Diffusion capacity. These results were compared with those of 30 women of similar ages not exposed to similar noise and not presenting respiratory disease.Statistical significance (P 10 anos com amplitude elevada e baixa frequência, susceptível de causar doença vibro-acústica (DVA.

    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.

    Full Text Available BACKGROUND: The assessment of multiple domains of physical activity is considered to be necessary for global physical activity surveillance and might be useful for the recognition of the effects of physical activity on health. 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.

Razvoj vojne opreme u svetu, naoružanja i druge tehnike zahteva nova shvatanja odbrane zemlje a zaostajanje se može sprečiti osavremenjavanjem naših oružanih snaga, kao i uvežbavanjem pripadnika Vojske Srbije u novim taktičkim postupcima i pripremanjem za eventualne nove forme suprotstavljanja agresiji. Uz međunarodnu saradnju i sticanje novih iskustava naša vojska osposobljena za učešće u multinacionalnim vojnim snagama. 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. Uz to, ovo je bila izvanredna prilika da se naši pripadnici RV i PVO obučavaju za spašavanje oborenih pilota. Vežba „Slovensko bratstvo 2016”, koja je usledila nakon zajedničkog uvežbavanja pilota Rusije i Srbije, doprinela je vojno-taktičkom osposobljavanju pripadnika Vojske Srbije za efikasno delovanje u protiv-terorističkoj borbi. Na toj vežbi učestvovali su pripadnici ruskih i beloruskih specijalnih snaga, kao i

    ční ve věku 61,95 ± 11,02 let. Podle metodiky kontroly PA byli pacienti rozděleni do tří skupin. Skupina 1 (G1 používala krokoměr, skupina 2 (G2 monitor srdeční frekvence a skupina 3 (G3 oba přístroje současně. Pacienti zapisovali počet kroků, trvání cvičení (G1 a G3 nebo průměrnou srdeční frekvenci (G2 a G3 do záznamových archů. Kontrola sledovaných laboratorních a klinických ukazatelů probíhala po 3, 6 a 12 měsících. VÝSLEDKY: Adherence k programu byla velmi variabilní (60-360 dní, nejnižší byla u pacientů skupiny G2 a nejvyšší ve skupině G3. Program dokončili pouze dva pacienti ze skupiny G3 (10 % z celkového počtu intervenovaných pacientů. Mezi jednotlivými skupinami jsme nezaznamenali statisticky významný rozdíl v žádném ze sledovaných ukazatelů kvality pohybové intervence (počet kroků, doba cvičení, odhad energetické spotřeby při cvičení. ZÁVĚRY: Jako nejvíce akceptovaný prostředek ke kontrole objemu PA se jevil krokoměr. Velmi nízká adherence vyplývá z pevné fixace většinou několik desítek let trvajícího sedavého životního stylu a často má psychologické a sociální příčiny.

    the pool. Refuelling was done three times by 'mixing' the irradiated fuel slugs with 5 to 6 fresh ones. Total exposure of the staff was increased due to activities during the shut-down period. Individual maximum exposure dose was not higher than 3.5 R. Cooperation with the French partner, concerned with the possibility of using 93% enriched fuel instead of the present low enriched, was continued. This would enable achievement of higher neutron flux, order of magnitude of 10{sup 14} n/cm{sup 2} sec. It is mentioned that there is doubt whether the plan for 1971 could be fulfilled for financial difficulties. [Serbo-Croat] Reaktor RA je u 1970. godini radio na nominalnoj snazi 160 dana i 40 dana na manjim snagama. Ukupni rad iznosio je 25968 MWh odnosno 3.87% vise od planiranog. Plan rada razlikovao se od prethodnih godina zbog slanja teske vode na rekoncentraciju u Francusku. Izotopski sastav teske vode je opao na 99.05% a posle rekoncentracije iznosi 99,96%. Odstupanje od plana rada u septembru mesecu bilo je izazvano kasnjenjem prispeca teske vode usled administrativnih teskoca i transporta. Pocetak kampanje odlozen je i zbog posledica ostecenja kosuljice jednog gorivnog elementa, sto se dogodilo odmah po pocetku rada pa je reaktor bio zaustavljen. U oktobru i novembru reaktor je radio 28 odnosno 25 dana respektivno sto je omogucilo da se nadoknadi izgubljeno vreme. Reaktor je koriscen za ozracivanja i eksperimente za 390 korisnika od cega 340 iz Instituta i 50 za korisnika izvan Instituta. Ovaj izvestaj sadrzi detaljne podatke o radu i eksperimentima koji su obavljani. Zakljucuje se da je reaktor radio uspesno prema planu rada. Kracih zastoja u radu bilo je samo zbog teskoca sa cevovodima tehnicke vode kao posledica klizanja zemljista. Reaktor je samo dva puta sigurnosno zaustavljan zbog neispravnosti opreme odnosno laznog signala elektronske aparature sistema upravljanja. Vreme dok reaktor nije radio iskorisceno je za inspekciju unutrasnjosti reaktorskog suda. Pomocu

Basandose en los resultados obtenidos con un solo elemento intensificador, se construyeron intensificadores de dos y tres etapas y se efectuaron experimentos para estudiar sus caracteristicas con diferentes resistencias montadas en paralelo. Con el intensificador de tres etapas se obtuvo una amplificacion del orden de 400, para una radiacion de entrada igual a 0,3 rdlux. Estos resultados sugieren la posibilidad de obtener un mayor aumento para una radiacion de entrada menor.

    Full Text Available U studiji pod tim naslovom autor razmatra postanak i razvoj tzv. Smjene ili alternacije morfema (tal. alternanza morfematica, engl. morphemic alternance u prezentu talijanskih glagola, od starotalijanskog do suvremenog talijanskog jezika. Dok u starom talijanslmm jeziku opažamo bujnost i koegzistenciju različitih tipova alternacije, suvremeni ju je jezik u velikom broju glagola ukinuo (generalizacijom jednog alomorfa. J edan od bitnih faktora ne samo postanka morfematske alternacije nego i njezina ukidanja jest i analogija, tj. težnja prema predvidivosti ili pretkazivosti glagolskih oblika na osnovu morfematskog sistema. Autor razlikuje tri tipa analogičkih utjecaja: utjecaj jednog člana neke paradigme na druge (intraparadigmatski u., utjecaj odrectenih članova jedne paradigme na članove druge paradigme istoga glagola (interparadigmatski u. i napokon utjecaj određenih oblika jednog glagola na oblike drugog glagola (interverbalni u.. U razvoju prezentskih obliika talijanskog glagola zastupana su sva tri tipa. Za razliku od nekih lingvista, autor razlikuje samo dva tipa morfematske alternacije: automatsku alternaciju, određenu mogućnostima fonematskog sistema i prema torne predvidivu, i leksičku alternaciju, tj. onu koja nije podređena restrikcijama fonematskog sistema i zbog toga nije predvidiva, odnosno predvidiva je samo nakon što prethodno utvrdimo odsječke leksika (u konkretnom slučaju glagole u kojima dolazi. Morfematska alternacija obaju tipova sudjeluje u izraža vanju morfosintaktiičkih opozicija, ali ona nije o njima ovisna u smislu predvidivosti, jer ne dolazi u s vi m glagolima. U glavnom dijelu priloga autor studira najprije one morfematske alternacije koje se osnivaju na alternaoiji vokala (altemanza, vocalica, što je opet posljedica nekih fonematskih procesa (diftongacije vokala /e/, /o/, razvoja diftonga /aw/, zaobljivanje nenaglašenoga fonema /e/ u dodiru s labijalnim konsonantima itd..

Ils donnent des indications techniques detaillees sur plusieurs systemes d'avertissement relativement simples. (author) [Spanish] El autor de la memoria examina toda la gama de los procesos de mezcla en la atmosfera, transporte y evacuacion. Ciertas mediciones indican que el aire estratosferico se renueva aproximadamente cada dos anos, lo que hace todavia menos atractiva de lo que se suponia la evacuacion de desechos radiactivos a gran altitud. Hasta cierto punto la precipitacion de materias radiactivas no es sistematicamente uniforme, y los niveles admisibles de radiactividad atmosferica deberian basarse en los riesgos probables en las regiones de maxima exposicion, es decir, aquellas regiones montanosas en que las precipitaciones son muy abundantes. En conexion con la medicion de la radiactividad atmosferica, se hace observar que los sistemas de muestreo deberian tener en cuenta los efectos probables del cambio gradual del tamano de las particulas y la eliminacion de particulas por precipitacion, colision y absorcion en las plantas, edificios, etc. En la memoria se examinan los problemas meteorologicos relacionados con el monitoraje de la radiacion y los sistemas de alarma en conexion con el funcionamiento de reactores.

    taille des echantillons et le degre de controle sont determines en fonction des risques inherents a la premiere et a la deuxieme condition. Bien que cette methode soit applicable, elle est fort peu pratique quand il s'agit de controler des pieces de reacteurs, car les echantillons qu'elle exige sont de dimensions excessives. Le memoire expose une methode analogue a celle de Cave mais qui consiste a etablir un double echantillonnage dans lequel la taille moyenne de l'echantillon est beaucoup plus reduite. (author) [Spanish] La fabricacion de componentes que han de ser empleados en reactores nucleares presenta dos caracteristicas fundamentales que condicionan el proceso: la exigencia de una calidad muy elevada que limita a valores muy bajos el porcentaje de piezas defectuosas admisibles, y el coste muy alto de cada uno de los componentes. Estas dos condiciones obligan a que el control durante la fabricacion posea una curva de operacion con potencia muy elevada, y, por otra parte, a que el numero de piezas destruidas en cada inspeccion sea un pequeno como se pueda, siempre que se cumpla la condicion anterior. Los metodos usuales de control, basados en fijar el riesgo de primera especie, no son aplicables, ya que en general su eficacia no es suficiente. Cave ha desarrollado un metodo en que, tanto el tamano de las muestras como los limites de control, se fijan en funcion de los riesgos de primera y segunda especie. Este metodo, si bien es aplicable, resulta poco practico en el control de componentes para reactores, ya que se necesitan muestras de un tamano excesivamente grande. En el presente trabajo se desarrolla un metodo semejante al de Cave, pero en el que se establece un muestreo doble, con lo que el tamano medio de la muestra es mucho mas reducido.

Realizacija programa probnog rada zapoceta je 15. septembra 1981. godine uz postupno povecanje snage tako da je u novembru i decembru reaktor radio na snazi od 2 MW u trajanju od 15 dana. Na reaktoru je u toku 1981. godine ostvaren rad od ukupno 1698 MWh. To je omogucilo da se reaktor u poslednja dva meseca koristi i za proizvodnju radioizotopa. Kontrola i odrzavanje celokupne opreme, kao i remontni radovi izvrsavani su redovno i efikasno u granicama koje su diktirane raspolozivoscu repromaterijalom i rezervnim delovima. Najvecu poteskocu pricinjava odrzavanje instrumentacije. Reaktor je u toku 1981. godine radio potpuno bezbedno i sigurno kako po osoblje tako i po ostalo ljudstvo u zgradi reaktora i van nje. Nije se dogodio ni jedan akcident vezan za rad reaktora. Probni rad ce biti nastavljen i u 1982. godini a dosadasnji rezultati pokazuju da ce ceo program biti uspesno realizovan.

    choix. Les theories sur la retrodiffusion permettent d'expliquer ces resultats. (author) [Spanish] El metodo se basa en el principio recientemente descrito por Failla y sus colaboradores: En un recinto en que se ha hecho el vacio se disponen paralelamente y a poca distancia entre si dos electrodos planos del mismo material. Sobre uno de ellos se deposita la fuente que se ha de medir. La retrodispersion en el electrodo portador de la fuente queda compensada por la reflexion en el otro electrodo. Un campo magnetico o electrico permite eliminar el efecto de los electrones secundarios de escasa energia.

(IVP’s scientists developed the lubricant eye drops (Can-C™ designed as 1% N-acetylcarnosine (NAC prodrug of L-carnosine containing a mucoadhesive cellulose-based compound combined with corneal absorption promoters in a sustained drug delivery system. Only the natural L-isomeric form of NAC raw material was specifically synthesized at the cGMP facility and employed for the manufacturing of Can-C™ eye drops.Objective and study design: In the present clinical study the authors assessed vision before and after 9 month term of topical ocular administration of NAC lubricant eye drops or placebo in 75 symptomatic patients with age-related uncomplicated cataracts in one or both eyes, with acuity in one eye of 20/40 or worse (best-corrected distance, and no previous cataract surgery in either eye and no other ocular abnormality and 72 noncataract subjects ranged in age from 54 to 78 years.Setting: Subjects in these subsample groups have reported complaints of glare and wanted to administer eye drops to get quick eye relief and quality of vision for their daily activities including driving and computer works. Following 9 months of treatment with NAC lubricant eye drops, most patients’ glare scores were improved or returned to normal in disability glare tests with Halometer DG. Improvement in disability glare was accompanied with independent improvement in acuity. Furthermore, patients with the poorest pretreatment vision were as likely to regain certain better visual function after 9

    ,996 y 2,0032, respectivamente. El estudio de la regeneracion por recocido del primer radical en el intervalo 60 Degree-Sign -170 Degree-Sign C revela la existencia de una cinetica con un solo rellano correspondiente a una recombinacion total de los radicales. Se ha podido establecer, para cada isoterma, la ecuacion correspondiente utilizando la funcion de errores deducida por Fletcher y Brown considerando el modelo de recombinacion de pares inicialmente correlacionados (y luego liberados) segun un proceso aleatorio. La concordancia entre los resultados experimentales y la funcion se obtiene corrigiendo esta mediante un factor alfa. La curva compuesta de recocido se ajusta muy bien a la funcion de errores corregida. Aplicando el metodo fenomenologico de Fletcher y Brown para calcular la energia de activacion, se ha hallado el valor de 1,594 eV, correspondiente al primer radical en el (NH{sub 4}){sub 2}SO{sub 4}. Basandose en la variacion del coeficiente de difusion con la temperatura, se ha determinado el valor de 1,592 eV para la misma energia de activacion. Aplicando el metodo de Vand-Primack se ha hallado el valor de 1,45 eV, menor que los dos anteriores. Se estima, en conclusion, que el modelo de recombinacion de pares correlacionados segun un proceso aleatorio es aplicable en la formula dada por la teoria cuando la interaccion de las especies formadas con la red es bastante debil; en esas condiciones, los pares correlacionados inicialmente pueden liberarse.

    Full Text Available U najopštijem smislu digitalna forenzika može se definisati kao skup metoda za prikupljanje, analizu i prezentaciju digitalnih dokaza koji se mogu pronaći na računarima, serverima, u računarskim mrežama, bazama podataka, mobilnim uređajima i svim drugim elektronskim uređajima na kojima se čuvaju podaci. 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

En ausencia de viento, una proporcion considerable del agua caliente retornaba a la central al cabo de tres o cuatro horas, circulando por la superficie del deposito. Ello puso de manifiesto que el sistema de admision del agua se habia proyectado incorrectamente, por lo que hubo de modificarse. El autor describe asimismo un estudio del esquema de circulacion de las soluciones de azucar bruto en un tanque Bach de sedimentacion. Despues de haber sido tratada con cal, la solucion caliente penetra en el tanque por una tuberia de alimentacion que desemboca en la parte superior del mismo, en tanto que la solucion clarificada se estrae por tuberias situadas a seis niveles distintos. Los solidos precipitados se extraen por la parte inferior. Se inyecto una solucion conteniendo 5 milicuries de bromo-82 en la tuberia de alimentacion y el paso del indicador se midio cuantitativamente a medida que aparecia en las seis tuberias de salida, utilizando detectores de centelleo blindados.

    observation; the level of dash performance mostly decreased. However, the last measurement in 2006 indicates some tendency of increasing performance as well as concavity of polynomial functions (trend function at the end of the observed time period. [VÝCHODISKA: Komplex sociálních změn, vzrůstající inaktivity a obezity a dalších negativních faktorů se dle našeho názoru přirozeně projevuje také ve změnách úrovně motorické výkonnosti budoucích vysokoškolských studentů. Dlouhodobý trend motorické výkonnosti proto považujeme za vhodný obraz současného životního stylu uvažované populace. CÍLE: Hlavním cílem této práce bylo popsat dlouhodobý trend dvou vybraných motorických předpokladů u populace uchazečů o vysokoškolské studium TV. METODIKA: Soubor tvořilo 2 012 mužů a 1 705 žen (uchazečů o vysokoškolské studium TV ve věku Mdn = 19 let. Úroveň plavecké a sprinterské výkonnosti byla zjišťována dvěma motorickými testy (plavání 100 m a běh 100 m u příležitosti přijímacího řízení v letech 1991 až 2001 a v roce 2006. VÝSLEDKY: Ve čtyřech případech (dva motorické testy, dvě pohlaví analýza ukazuje na nenulový trend výkonnosti (ve všech případech byl alespoň jeden meziroční rozdíl signifikantní na p = 0,05. V případě sprinterské a plavecké (pouze muži výkonnosti vykazují polynomické funkce trendu v počátku konvexní, později konkávní průběh (změna průběhu v letech 1998–1999. Trend plavecké výkonnosti žen je rostoucí v celé periodě. Konkávnost polynomické funkce naznačuje možnost opětovného nárůstu výkonnosti, jež byla v období 1993–2001 (sprint a 1996–1999 (plavání převážně klesající. ZÁVĚRY: Na základě našich zjištění zamítáme výzkumnou hypotézu a konstatujeme tak existenci významných změn v úrovni plavecké a sprinterské výkonnosti v průběhu sledované periody.

    : infiltracion del agua a traves de los sectores mas permeables del estrato, a velocidades comprendidas entre 10 y 30 m por dia, y avance del contorno basico de agua bombeada en una parte relativamente homogenea del estrato, a una velocidad de 2 m por dia. Este ultimo desplazamiento corresponde a las velocidades (1,9 a 2,2 m por dia) calculadas teoricamente para un estrato homogeneo. Es posible evaluar cuantitativamente el flujo en los desplazamientos de ambos tipos. Se ha ideado un metodo que emplea tritio para observar la comunicacion entre las aguas presentes en los distintos sectores intercalados en el estrato productivo de una vena petrolifera. Los autores proponen un metodo nuevo para controlar la explotacion de yacimientos petroliferos gracias al tritio natural contenido en las aguas superficiales inyectadas en el estrato, tanto en el interior como en el exterior del contorno. El lento desplazamiento del contorno de yacimientos petroliferos grandes, en los que se hayan realizado pocas perforaciones, puede ser estudiado durante periodos largos (unos 10 anos). De la cantidad de tritio desintegrado que contenga el agua subyacente a 1a. capa petrolifera de un pozo en explotacion pueden deducirse los tiempos y velocidades de desplazamiento del agua de contorno con una exactitud de {+-} 1 ano. Basta un numero reducido de analisis (no mas de 300 a 500 analisis por ano en un gran yacimiento) para seguir el desplazamiento del contorno. Se ha ideado un aparato sumamente sensible para medir el tritio en las aguas superficiales con contadores contrastados llenos de liquido. La mayor parte de las organizaciones industriales puede disponer de aparatos de este tipo.

    efecto combinado de un filtro de Be y un selector con una curva de transmision estrecha. En este espectrometro, lo mismo que en el de Estocolmo, el selector se coloca delante de la muestra para poder registrar simultaneamente datos a diferentes angulos de observacion. En el reactor R2 se encuentra tambien instalado un espectrometro triaxial de cristal. Los autores describen diversas caracteristicas de los instrumentos, tales como las intensidades y los poderes de resolucion alcanzados, e indican en que medida se adaptan a ciertas determinaciones. Demuestran con datos numericos que un aumento relativamente pequeno del poder de resolucion ocasiona una elevada perdida de intensidad. Cuando se comparan los reactores RI y R2 como fuentes neutronicas para experimentos en el orificio de haz, es interesante observar que, si bien el flujo neutronico del reactor R2 es 100 veces mayor, el rendimiento en neutrones es unas 10 veces menor. El fenomeno se debe a la estrechez de los orificios de haz y a los filtros que son necesarios para reducir los flujos gamma y de neutrones rapidos. Como ilustracion, la memoria discute brevemente datos de dispersion en H{sub 2}O obtenidos con los diversos instrumentos. La comparacion demuestra que, para experimentos con el orificio de haz, el reactor de agua pesada presenta ventajas innegables.

El sondeo radial del plasma acusaba un aumento considerable de la corriente colectada hacia el centro, con una disminucion simultanea del tiempo de decrecimiento. Las mediciones sugieren que, durante la inyeccion, se acumula una carga espacial positiva en el centro, que va llenando continuamente la region exterior, mas adiabatica, de la cuspide. Despues de interrumpir el haz, el numero de particulas de la region no adiabatica disminuye con rapidez, mientras que las particulas de la region adiabatica desaparecen mas lentamente (50 {mu}s).

    Full Text Available Donošenje odluka o prostornom raspoređivanju opasnih materija neophodno je zbog minimiziranja rizika po okolinu. U ovom radu razmatran je problem lociranja različitih vrsta opasnih materija (sa različitim karakteristikama. 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. Verifikacija modela sprovedena je i ilustrovana na generisanom hipotetičkom primeru čiji su rezultati prikazani. / Making decisions about dangerous goods positioning is crucial when it is necessary to minimize environmental risks. In this paper, a specific problem of locating various kinds of dangerous goods (with different characteristics has been considered. Such goods should be located in a known discrete set of potential storage sites, under condition of the minimum safety distance (MSD between selected locations. The existence of the MSD is a consequence of the possibility that dangerous goods transfer their undesirable effects to the objects in the neighborhood. The objective here is to maximize the quantity of different kinds of dangerous goods stored meanwhile

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.

    annotacii my podvodim itog nedavnej raboty po izucheniju vzaimodejstvija jelektronnogo puchka s plazmoj, prodelannoj v Massachuzetskom tehnologicheskom institute. Kogda jelektronnyj puchok prohodit cherez plazmu, on vozbuzhdaet kolebanija na plazmennoj chastote. Jeti mikrovolnovye kolebanija podderzhivajut mikrovolnovyj razrjad, i my nazvali ves' process ''puchkovym razrjadom'. Ionizacija okruzhajushhego gaza osushhestvljaetsja jelektronami vysokoj jEhnergii iz plazmy, kotorye uskorjajutsja poljami kolebanij. Rezul'tatom javljaetsja obrazovanie gorjachej jelektronnoj plazmy vnutri ustanovki s magnitnymi probkami. Poskol'ku parametry razrjada puchka v plazme predstavljajutsja neblagoprijatnymi dlja neposredstvennogo ionnogo nagreva vzaimodejstviem puchka s plazmoj, my pristupili k jeksperimentam, v kotoryh dopolnitel'naja radiochastotnaja jenergija nakladyvaetsja s cel'ju vozbuzhdenija ciklotronnyh kolebanij ionov dlja ionnogo nagreva. Rassmotreniju podlezhat ustojchivost' plazmy; plotnost', srednjaja jenergija i maksimal'naja jenergija jelektronov plazmy; i predvaritel'nye rezul'taty po ionnomu nagrevu. Provodjatsja jeksperimenty s pul'sirujushhim jelektronnym puchkom v 10-15 kv i 10 - 15 A, kotoryj inzhektiruetsja vdol' osi magnitnyh probok v'oblast' drejfa, soderzhashhuju H{sub 2} np 10{sup -5}-10{sup -4} torr. Plotnost' jelektronov plazmy ob{sup e}mom v 1 litr obychno sostavljaet 10{sup 12}-10{sup 13} sm{sup -3} i plotnost' poperechnoj jEhnergii obychno sostavljaet 10{sup 15} jev/sm{sup 3}, chto sootvetstvuet temperature poperechnyh jelektronov v 10{sup 2}-10{sup 3} jev. Izmerenie jenergij rentgenovskih luchej ukazyvaet na sushhestvovanie' jelektronov s jenergiej 50-100 kjev. Spad plazmy posle vykljuchenija puchka proishodit v dva jetapa: otnositel'no bystraja poterja jelektronov nizkoj jEhnergii, {tau} Less-Than-Or-Equal-To 1000 mksek, i medlennyj spad jelektronov vysokoj jEhnergii s {tau} = 10-50 msek.

    řipomínkovým řízením. V rubrice Informace uvádíme dva příklady dobré praxe zařazené do tzv. EU Inventory of innovative good practice on education for sustainable development; pokud se zajímáte o ekonomii životního prostředí, všimněte si analytického pohledu na tři kurzy Aleše Lisy a Petra Šauera. Až nakonec se dostáváme k vlajkové lodi našeho časopisu – recenzovaným textům, které jsme pro vás do tohoto čísla připravili. Pavel Žďárský píše o Frommově interpretaci dvou cest člověka, které se manifestují buď v aktivním „biofilním“ postoji a orientaci ke světu, nebo opačné „cestě smrti“. Karol Herian uvažuje nad proměnami ekologického myšlení v souvislosti s vývojem systémových konceptů organického světa; hledá přístupy neredukující jeho složitost a specifika. Jan Činčera se věnuje dvěma protikladným přístupům environmentální výchovy; na základě svých teoretických úvah vyvozuje také závěry pro konkrétní vzdělávací strategie. Tento text těsně souvisí s nerecenzovaným (protože převzatým článkem Marie Öhman & Johan Öhman: Power in action... který se na rozpory ve vzdělávacích konceptech dívá zase z jiné strany. Jiří Nečas znovu klade otázku Opravdu chceme trvale udržitelný rozvoj? Můžeme ji číst s důrazem na jednotlivá slova (Chceme? Trvale? Udržitelný? Rozvoj?, ale má i další dimenzi (Chceme-li opravdu, tedy jak?. Odpovídá (běžným sice, ale nepříliš praktikovaným názorem, že rozvoj se nám děje tak trochu nezávisle na našem chtění; a je třeba se opřít o etické imperativy, abychom jej usměrnili. Článek navíc doplňuje velmi podrobná recenze Ivana Ryndy, kterou zahajuje dialog na dané téma. Měli byste dále vědět, že článek Kateřiny Jančaříkové z minulého čísla Žákovské portfolio – vhodná forma hodnocení environmentální výchovy (3/2007 byl úspěšně recenzován a je tedy přeřazen do

    korozije. U vakuum komori nalazi se: obrtni sto, planetarni sistem sa 48 alata, šestoosni robot i veštačka ruka. 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

    indica en la memoria, se puede conseguir la estabilizacion incluso en el caso limite de barras muy cortas, en el cual se las puede considerar como un sistema de 2n dipplos magneticos puntiformes, situados en, el plano central de la trampa de espejos, en una circunferencia de radio a y dirigidos en sentido radial desde el eje (o hacia el eje - las direcciones alternan). Estos sistemas, que hemos considerado a propuesta de Artsimovich, pueden ofrecer muy buenas perspectivas, ya que su estructura simplifica el acceso al plasma y permite instalar un equipo complementario para el diagnostico o el calentamiento del plasma.

    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.
