    Because of the design and specific implantation technique of the stentless Freedom SOLO bioprosthesis, patient selection is crucial. The aim of the study was to discuss the contraindications to this prosthesis based on the authors' implant experience. Between April 2005 and February 2015, one surgeon at the authors' center performed 292 aortic valve replacements using a bioprosthesis, with the initial intention of implanting a SOLO valve in every patient. A search was conducted for all of these patients and data collected on whether a SOLO valve was used, or not. A SOLO valve was implanted in 238 patients (82%), and a stented bioprosthesis in 54 (18%). The predominant reasons not to implant a SOLO valve were asymmetric commissures (26%) and a large aortic annulus (24%). Only one patient had structural valve deterioration, and none of the patients had to undergo reoperation because of aortic valve insufficiency or paravalvular leakage. Asymmetric commissures, large aortic annulus (>27 mm), calcified aortic sinuses, dilated sinotubular junction, aberrant location of coronary ostia and whenever the stent of a stented bioprosthesis is useful, were contraindications to implant a SOLO valve. When these contraindications were taken into account, a very good durability could be achieved with the SOLO valve during mid-term follow up.

    This study reviews a single institution experience with the Freedom SOLO (Sorin Group, Saluggia, Italy) aortic bioprosthesis. Between October 2006 and February 2010, 128 patients (64 men, 64 women; mean age, 75.8 ± 5.1 years) underwent aortic valve replacement using the Freedom SOLO stentless aortic valve. The follow-up time was 36.7 ± 1.2 months and 100% complete. Concomitant procedures were performed in 77 patients (60%). The mean standard European System for Cardiac Operative Risk Evaluation was 9 ± 2.7. Grade 3 aortic stenosis was present in 73% of patients, mixed aortic stenosis and regurgitation were present in 40% of patients, and mitral regurgitation was present in 46% of patients. The mean crossclamp time was 53 ± 12 minutes for isolated Freedom SOLO aortic valve implantation and 80 ± 28 minutes for concomitant procedures, and the mean cardiopulmonary bypass time was 103 ± 31 minutes. The mean implanted valve size was 22.6 ± 1.4 mm. The mean intensive care unit and hospital stays were 2.4 ± 1.1 days and 8.8 ± 2.6 days, respectively. Three patients underwent reoperation for bleeding. The 15-day, 30-day, and perioperative mortality were all 4.6%. The 36-month survival was 95.4% ± 1.6% for the cohort with a low European System for Cardiac Operative Risk Evaluation (9). Echocardiographic data preoperatively, immediately postoperatively, and at 3, 6, and 12 months postoperatively showed peak transvalvular gradients of 75 ± 23, 17 ± 6, 18 ± 6.5, 16 ± 6, and 16 ± 9 mm Hg, respectively (P SOLO stentless aortic valve has excellent early and intermediate-term results.

    This paper examines human-nature interaction and how therapeutic this relationship is by investigating the efficacy of structured outdoor experience. Two walking and solo experience (WSEs) explored university students' (aged 20-43 years) perceptions of walking through and being with nature. The first was a 5-day journey (n = 4; 3 females and 1 male) and the second (n = 5; 3 females and 2 males) took place over two weekends, with a 2-week interval in-between. Pre- and post-experience interviews, journal writing, group discussions and a 9-month follow-up interviews were used to collect data and thematic analysis [Braun and Clarke (Using thematic analysis in psychology. Qual Res Psychol 2006;3:77-101.)] was applied. Both WSEs were considered together during analysis, as well as comparisons made between the two, in order to evaluate implications for practice. Benefits of the WSE that contributed to a general sense of well-being were: (i) gaining a sense of freedom and escape; (ii) gaining a sense of awareness and sensitivity to one's environment and its influence (iii) gaining confidence in being able to cope and take action; (iv) gaining a sense of perspective on and appreciation for life. Furthermore, the meaning participants formed in relation to their environment before, during and after the WSE, and the activity within that environment, played a role in their sense of well-being and in their motivations to re-access nature in other places. Findings suggest that WSEs are a cost effective way to give rise to beneficial and durable experiences, but a more holistic approach to policy is needed. © The Author 2016.

    Full Text Available Abstract. The linkage among information-intensive era, technology, and tourism industry build inseparable genetic relationship which is supposed to be realized in practice. Let alone in this digital era, the urgency to exploit information to the next level resulted in the need to bring a higher game on the technology in order to manage information effectively and efficiently. Tourism industry is categorized as complex system regarding the components substituted it. The diverse elements which interact with dynamics pace give birth to complex tasks to manage by the responsible parties and consequently enhance experience in tourism industry. Competing with complex situation, computerized decision system is urgently needed to collect and also distribute accurate knowledge of tourism industry, collaborate with both supporting public and private sectors, and gain rationality for all stakeholders in the system. Solo city, known also as Surakarta and located in Central Java (Indonesia, is obliged to do its tourism industry justice as it is an important vehicle for regional development of the city. Tourism industry of Solo city represents the major and significant contributor to the local economy to the point where tourism is the brand of Solo city. Taking the prior research finding, value orchestration platform to promote tourism in batik Solo industrial cluster into the reference, this study improves the model by highlighting the duality function the tourism website supposed to have using hashtag (# minings principle as the latest user interface technology. This study proposes a collaborative website platform as a co-created decision support system to enhance tourism experience for tourist as consumer and optimize management process for Department of Culture and Tourism of Solo city as provider.

    Freedom Solo is a stentless biological aortic valve which is implanted supra-annularly with a single suture line. An increased risk of postoperative thrombocytopenia in the early postoperative period has been reported in recent studies. In our study we evaluated postoperative haemodynamic performance and thrombocyte-levels. Thirty seven patients who underwent valve implantation of the Sorin Freedom Solo stentless valve were included. The haemodynamic performance of the valve was evaluated by transthoracic echocardiography postoperatively at the fourth day (mean) and after a median of 4.2 months. The mean gradient (mmHg) of Freedom Solo was 7.5 at four days and 8.6 at 4.2 months. Postoperatively no patient had more than grade 1 leakage. Seven percent of the patients had a reduction of thrombocytes to less than 20% of the preoperative level. Seventy six percent had a minimum postoperative thrombocyte level less than 100*10(9)/L. The 30 days mortality in our patient material was zero. Implantation of the Freedom Solo valve was uncomplicated in our experience. Favourable transvalvular gradients and no significant leaks were found. In accordance with the literature, we found a high percentage of patients having a postoperative level of thrombocytes less than 100*10(9)/L after implantation of Freedom Solo.

    Full Text Available Objective: Burnout is conceptualized as a syndrome that consists of emotional exhaustion, depersonalization, and decreased personal accomplishment. Despite the increased frequency and severity of burnout in the Western world, there is limited published research regarding the experiences of clinical psychologists who have had burnout. The present study examines clinical psychologists’ different experiences of burnout in Australia.Design and Methods: In the year 2015, six privately practicing and solo-employed clinical psychologists provided rich qualitative data by participating in semi-structured interviews. Thematic analysis was the method used to analyze clinical psychologists’ natural accounts of their burnout experiences. Using NVivo, emerging themes were identified through coding ‘first order constructs’ and then axial code ‘second order constructs.’Findings: Clinical psychologists indicated that their roles are demanding and a diverse range of symptoms, including the enduring effects of burnout, mental stress, fatigue, decreased personal accomplishment, negative affect, depersonalization, reduced productivity and motivation, and insomnia. They identified precursors of burnout, including excessive workload and hours of work, life stresses, mismanaged workload, and transference. Clinical psychologists suggested that protective factors of burnout include knowledge and years worked in direct care, and trusting and long-term relationships. They indicated that the barriers to overcoming burnout include the fallacy that their clients’ expectations and needs are more important than their own, the financial cost of working in private practice, contemporary knowledge and inadequate education regarding self-care, and time constraints.Discussion and Conclusion: The findings presented in this study provide psychologists and other health professionals with an insight about the burnout experience and inform professionals of the mental

    To report our institutional experience and long-term results with the Freedom Solo bovine pericardial stentless bioprosthesis (Sorin Group, Saluggia, Italy). Between January 2005 and November 2009, 149 patients (mean age, 73.6 ± 8.7 years; 68 [45.6%] female) underwent isolated (n = 75) or combined (n = 74) aortic valve replacement (AVR) using the Solo in our institution. Follow-up was 100% complete with an average follow-up time of 5.9 ± 2.6 years (maximum, 9.6 years) and a total of 885.3 patient years. Operative (30-day) mortality was 2.7% (1.3% for isolated AVR [n = 1] and 4.0% for combined procedures [n = 3]). All causes of death were not valve-related. Preoperative peak (mean) gradients of 74.2 ± 23.0 mm Hg (48.6 ± 16.3 mm Hg) decreased to 15.6 ± 5.4 mm Hg (8.8 ± 3.0 mm Hg) after AVR, and remained low for up to 9 years. The postoperative effective orifice area was 1.6 ± 0.57 cm(2), 1.90 ± 0.45 cm(2), 2.12 ± 0.48 cm(2), and 2.20 ± 0.66 cm(2) for the valve sizes 21, 23, 25, and 27, respectively, with absence of severe prosthesis-patient mismatch and 0.7% (n = 1) experienced moderate prosthesis-patient mismatch. During follow-up, 26 patients experienced structural valve deterioration (SVD) and 14 patients underwent explantation. Kaplan-Meier estimates for freedom from death, explantation, and SVD at 9 years averaged 0.57 (range, 0.47-0.66), 0.82 (range, 0.69-0.90), and 0.70 (range, 0.57-0.79), respectively. The Freedom Solo stentless aortic valve is safe to implant and shows excellent early and midterm hemodynamic performance. However, SVD was observed in a substantial number of patients after only 5-6 years and the need for explantation increased markedly, suggesting low durability.

    Eighteen tumors of the pineal region were treated at Thomas Jefferson University Hospital since 1957. Preoperative evaluation included CT scan in 11 patients and cerebrospinal fluid cytology in four. Histologic diagnosis was obtained in nine patients. Diagnosis in two other patients was based on CT scan response at 2,000 cGY. Fifteen patients received whole-brain irradiation with a boost, one each with limited-field and whole-brain irradiation only. One patient with melanoma received craniospinal irradiation. Median pineal dose was 55 Gy; range, 50-60 Gy. Five treatment failures occurred, four local and one distant. Actuarial survival was 80%, 70%, and 65% at 5, 10, and 20 years. Median follow-up was 8.8 years. Cranial radiotherapy alone appears to control the majority of pineal tumors

    The Solo Smart pericardial aortic valve has been widely used in Europe as an option for aortic valve replacement (AVR). We are reporting early and midterm clinical outcomes of AVR with the Solo Smart valve in a single North America center. This is a retrospective study of 270 consecutive patients who had AVR at Mazankowski Alberta Heart Institute from February 2011 to March 2015. Follow-up and echocardiographic data were collected retrospectively from electronic and paper charts. Univariate and multivariate analysis were performed to evaluate the results. The mean age was 71.2±10.0 years, 67.4% were male, and 79.3% had combined procedures. Mean STS Score was 4.18±3.91. Early mortality was 3.7% for the entire group and 0% for isolated aortic valve replacement group. Mean cross-clamp time for isolated AVR and AVR with concomitant procedure was 70.8±12.7min and 117.0±45.0min, respectively. Permanent pacemaker implantation was necessary in 2.2% of patients. Echocardiography demonstrated a reduction in mean gradients from 40.8±17.4mmHg to 7.6±3.7 mmHg and peak gradient from 72.5 ± 48.8 mmHg to 15.5±7.5 mmHg. The 1-, 3-, and 5- year overall survival was 93.0%, 86.5% and 75.9%, respectively. At 5 years, freedom from valve-related death was 92.4%, freedom from structural valve deterioration and freedom from aortic valve reoperation were 96.4% and 98%, respectively. The Solo Smart valve is safe and has excellent hemodynamic performance. Aortic valve reoperation and rates of valve-related adverse events during midterm follow-up were low.

Estudaram-se a produção total do ano, de junho a dezembro, e a parcial dos primeiros meses de colheita, junho a julho, quando é maior o valor do produto. A variedade utilizada foi a Campinas IAC-2712, a mais cultivada no Estado de São Paulo. O delineamento do ensaio foi o de blocos ao acaso, com oito tratamentos e cinco repetições. As coberturas do solo foram as seguintes: plástico preto, com 0,0762 mm de espessura, e cobertura morta, da qual experimentaram-se as seguintes: casca de arroz, restos de plantas de arroz picados, capim-favorito (Rhynchelitrum roseum picado e seco, bagaço de cana-de-açúcar picado, restos de madeira de marcenaria picados. Foram estudados mais dois tratamentos, sem cobertura do solo: a com escarificação do solo até cerca de dois centímetros de profundidade, cada 14 dias, para facilitar a penetração de água de irrigação; b sem escarificação do solo. A cobertura do solo aumentou sensivelmente a produção total, além de evitar que os frutos se sujassem de terra. Considerando a produção total, os tratamentos com cobertura morta não diferiram entre si; o tratamento com plástico preto e aquele sem cobertura do solo, porém escarificado cada 14 dias, não diferiram entre si, mas foram inferiores a todos os outros tipos de cobertura morta (Tukey 5%. O tratamento com plástico preto foi superior somente ao tratamento sem cobertura do solo e sem escarificação (Tukey 5%.

  6. Pipe failure probability - the Thomas paper revisited

    International Nuclear Information System (INIS)

    Lydell, B.O.Y.

    2000-01-01

    Almost twenty years ago, in Volume 2 of Reliability Engineering (the predecessor of Reliability Engineering and System Safety), a paper by H. M. Thomas of Rolls Royce and Associates Ltd. presented a generalized approach to the estimation of piping and vessel failure probability. The 'Thomas-approach' used insights from actual failure statistics to calculate the probability of leakage and conditional probability of rupture given leakage. It was intended for practitioners without access to data on the service experience with piping and piping system components. This article revisits the Thomas paper by drawing on insights from development of a new database on piping failures in commercial nuclear power plants worldwide (SKI-PIPE). Partially sponsored by the Swedish Nuclear Power Inspectorate (SKI), the R and D leading up to this note was performed during 1994-1999. Motivated by data requirements of reliability analysis and probabilistic safety assessment (PSA), the new database supports statistical analysis of piping failure data. Against the background of this database development program, the article reviews the applicability of the 'Thomas approach' in applied risk and reliability analysis. It addresses the question whether a new and expanded database on the service experience with piping systems would alter the original piping reliability correlation as suggested by H. M. Thomas

Beginning in the 20th century, doctors and scientists have looked to others for ideas, suggestions, innovations, and new technologies. Probably no one in the past hundred years has done so much to change the world than Thomas Edison. This article will discuss eight principles of Edison and how they may apply to our profession and our practices.

Median time to failure was 7 years. Patients were high risk (mean STS/Logistic EuroScore 10.6 15.8, respectively). FS valves ranged from 21 to 25 mm. Successful ViV-TAVI was achieved in 4/6 patients (67%). Of the unsuccessful cases, (patient 1 and 2 of series) patient 1 underwent BAV with simultaneous aortography which revealed left main stem occlusion. The procedure was stopped and the patient went forward for repeat surgery. Patient 2 underwent successful ViV-TAVI with a 26-mm CoreValve with a guide catheter in the left main, but on removal coronary obstruction occurred, necessitating valve snaring into the aorta. Among the successful cases, (patients 3, 4, 5, 6) the TAVIs used were CoreValve Evolut R 23 mm (n = 3), and Lotus 23 mm (n = 1). In the successful cases the peak gradient fell from 83.0 to 38.3 mm Hg. No patient was left with >1+ AR. One patient had a stroke on Day 2, with full neurological recovery. Two patients underwent semi-elective pacing for LBBB and PR >280 ms. ViV-TAVI in stentless Freedom Solo valves is high risk. The risk of coronary occlusion is high. The smallest possible prosthesis (1:1 sizing) should be used, and strategies to protect the coronary vessels must be considered. © 2016 Wiley Periodicals, Inc. © 2016 Wiley Periodicals, Inc.

  10. A novel self-expanding fully retrievable intracranial stent (SOLO): experience in nine procedures of stent-assisted aneurysm coil occlusion

    The endovascular treatment of large and broad-necked aneurysms may require the use of a remodelling balloon or a stent system to achieve proper occlusion while maintaining the patency of the parent vessel. With the advent of self-expanding stents that can be delivered through a microcatheter, this kind of treatment has improved and problems with the previously used balloon expandable stents have largely been overcome. However, rigidity, insufficient trackability, and limited or non-existent retrievability may still restrict the application of self-expanding stents in some situations. Recently, a stent system with a new and different design has been introduced. This stent is highly flexible, fully retrievable, and can be delivered through a standard 0.021-inch microcatheter without a wire. We describe the first nine cases of stent-assisted coil occlusion of intracranial aneurysms with the use of this stent system. Between May and June of 2004, nine patients with large or broad-necked aneurysms were treated in two endovascular centres. The anatomy of the aneurysms and parent vessels, technical details of the procedure, performance of the stent system, and follow-up results were evaluated. In all procedures, the SOLO stent could be introduced without difficulty, in one procedure after positioning of a different self-expanding stent system had failed due to vessel tortuosity. Overlapping stents were placed in one patient and stent retrieval or repositioning was successfully performed in two procedures. There was no interference or limitation of subsequent coil occlusion after stenting. With regard to the stent, immediate postprocedure and follow-up angiograms were unremarkable in terms of thromboembolic events and signs of intimal hyperplasia. From our experience, we conclude that the SOLO stent shows satisfactory performance overall. Its unique design gives the stent properties that may help overcome some of the difficulties experienced with other self

    observed. Firstly, solo livers emphasize independence from others as important. Several of the informants have had negative experiences with living together with a partner, and they like the feeling of being independent. At the same time, most informants also keep a door open for the possibility of moving...... together with "the right one", which indicates that ambiguity is related to the situation of solo living. Secondly, some of the solo livers spend more time outside home (occupied by leisure activities or together with friends) compared to people living in family households in general, which suggests...... a different balance between time at home and outside home for some solo livers....

    A three-dimensional density-functional molecular-dynamics code is developed for the Thomas-Fermi density functional as a prototype for density functionals using only the density. Following Car and Parrinello [Phys. Rev. Lett. 55, 2471 (1985)], the electronic density is treated as a dynamical variable. The electronic densities are verified against a multi-ion Thomas-Fermi algorithm due to Parker [Phys. Rev. A 38, 2205 (1988)]. As an initial application, the effect of electronic polarization in enhancing ionic diffusion in strongly coupled plasmas is demonstrated

    Introduction. Solo practices have generally been viewed as forming a homogeneous group. However, they may differ on many characteristics. The objective of this paper is to identify different forms of solo practice and to determine the extent to which they are associated with patient experience of care. Methods. Two surveys were carried out in two regions of Quebec in 2010: a telephone survey of 9180 respondents from the general population and a postal survey of 606 primary healthcare (PHC) practices. Data from the two surveys were linked through the respondent's usual source of care. A taxonomy of solo practices was constructed (n = 213), using cluster analysis techniques. Bivariate and multilevel analyses were used to determine the relationship of the taxonomy with patient experience of care. Results. Four models were derived from the taxonomy. Practices in the "resourceful networked" model contrast with those of the "resourceless isolated" model to the extent that the experience of care reported by their patients is more favorable. Conclusion. Solo practice is not a homogeneous group. The four models identified have different organizational features and their patients' experience of care also differs. Some models seem to offer a better organizational potential in the context of current reforms.

    Science.gov (United States)

    White, Judith B

    2008-09-01

    When everyone in a group shares a common social identity except one individual, the one who is different from the majority has solo status. Solo status increases one's visibility and performance pressure, which may result in stress. Stress has divergent effects on performance, and individuals' response to stressful situations is predicted by their cognitive appraisal (challenge or threat) of the situation. Two experiments test the hypothesis that cognitive appraisal moderates the effect of solo status on performance. Experiment 1 finds that at relatively high appraisal levels (resources exceed demands), solo status improves men's and women's performance; at relatively low appraisal levels, solo status hurts performance. Experiment 2 replicates this effect for solo status based on minimal group assignment. Results suggest that for individuals who feel challenged and not threatened by their work, it may help to be a solo.

    We consider a particle dressed with boundary gravitons in three-dimensional Minkowski space. The existence of BMS transformations implies that the particle’s wavefunction picks up a Berry phase when subjected to changes of reference frames that trace a closed path in the asymptotic symmetry group. We evaluate this phase and show that, for BMS superrotations, it provides a gravitational generalization of Thomas precession. In principle, such phases are observable signatures of asymptotic symmetries.

    issue. I have since narrowed the likely source of the error down to a Software Development Kit released by the camera supplier PixeLink. I have since developed a workaround in order to build star grids for calibration until the software bug can be isolated and fixed. I was also tasked with building a Hardware in the Loop test stand in order to test the full Op-Nav system. A 4k screen displays simulated Lunar and Terrestrial images from a possible Orion trajectory. These images are then projected through a collimator and then captured with an Op-Nav camera controlled by an Intel NUC computer running flight software. The flight software then analyzes the images to determine attitude and position, this data is then reconstructed into a trajectory and matched to the simulated trajectory in order to determine the accuracy of the attitude and position estimates. In order for the system to work it needs to be precisely and accurately aligned. I developed an alignment procedure that allows the screen, collimator and camera to be squared, centered and collinear with each other within a micron spatially and 5 arcseconds in rotation. I also designed a rigid mount for the screen that was machined on site in Building 10 by another intern. While I was working in the EOL we received a $500k Orion startracker for alignment procedure testing. Due to my prior experience in electronics development, as an ancillary duty, I was tasked with building the cables required to operate and power the startracker. If any errors are made building these cables the startracker would be destroyed, I was honored that the director of the lab entrusted such a critical component with me. This internship has cemented my view on public space exploration. I always preferred public sector to privatization because, as a scientist, the most interesting aspects of space for me are not necessarily the most profitable. I was concerned that the public sector was faltering however, and that in order to improve human

A grande concentração populacional em centros urbanos cada vez maiores tem dirigido a atenção de diferentes profissionais para o recurso solo, no sentido de entender sua dinâmica para minimizar sua degradação. No entanto, a falta de conhecimento sobre as propriedades, bem como sobre a aptidão dos solos sob uso urbano tem provocado o seu mau uso, resultando em processos como compactação, erosão, deslizamentos e inundações, assim como poluição com substâncias orgânicas, inorgânicas e patógenos, aumentando os custos do desenvolvimento afetando toda a sociedade. Neste sentido, este texto discute como o conhecimento pedológico pode diminuir os efeitos negativos provocados pelo processo de urbanização.The strong pressure caused by the disordered urban expansion over the natural resources, mainly the soils, has caused damages, many times difficult to repair.

    An Act of Parliament in 1540 uniting the barbers and surgeons to form the Barber-Surgeons' Company represented an important foundation stone towards better surgery in England. Thomas Vicary, who played a pivotal role in promoting this union, was a leading surgeon in London in the middle of the 16th century. While Vicary made no direct contribution to surgical knowledge, he should be remembered primarily as one who contributed much towards the early organization and teaching of surgery and to the consequent benefits that flowed from this improvement.

    Nonextensive Thomas-Fermi model was father investigated in the following directions: Heavy atom in strong magnetic field. following Shivamoggi work on the extension of Kadomtsev equation we applied nonextensive formalism to father generalize TF model for the very strong magnetic fields (of order 10e12 G). The generalized TF equation and the binding energy of atom were calculated which contain a new nonextensive term dominating the classical one. The binding energy of a heavy atom was also evaluated. Thomas-Fermi equations in N dimensions which is technically the same as in Shivamoggi (1998) ,but behavior is different and in interesting 2 D case nonextesivity prevents from becoming linear ODE as in classical case. Effect of nonextensivity on dielectrical screening reveals itself in the reduction of the envelope radius. It was shown that nonextesivity in each case is responsible for new term dominating classical thermal correction term by order of magnitude, which is vanishing in a limit q->1. Therefore it appears that nonextensive term is ubiquitous for a wide range of systems and father work is needed to understand the origin of it.

    Thomas J. Ahrens, a leader in the study of high-pressure shock wave and planetary impact phenomena, died at his home in Pasadena, Calif., on 24 November 2010 at the age of 74. He was the California Institute of Technology's Fletcher Jones Professor of Geophysics, emeritus since 2005 but professionally active to the end. He had been president of AGU's Tectonophysics section, editor of Journal of Geophysical Research, founding member of both the Mineral and Rock Physics and Study of the Earth's Deep Interior focus groups, and editor—more like key driving force—for AGU's Handbook of Physical Constants. Tom was a pioneer in experimental and numerical studies of the effects of projectiles hitting a target at velocities exceeding the speed of sound (hypervelocity impact), arguably the most important geophysical process in the formation, growth, and, in many cases, surface evolution of planets. As a professor at Caltech, he established the foremost university laboratory for shock wave experiments, where students and research associates from around the world pursued basic research in geophysics, planetary science, and other disciplines. Previously, high-pressure shock experiments were conducted primarily in national laboratories, where they were initially associated with the development of nuclear weapons.

Although the tinfoil phonograph’s first decade has been well documented by media historians, literary critics have singled out 1888 as the noteworthy year since that is when Edison’s improved phonograph made it possible to record prominent figures including Alfred Tennyson and Robert Browning. Taking Edison’s original tinfoil phonograph as an alternative starting point reveals how the 1878 phonograph demonstrations, despite technological limitations, undertook acoustic experiments that enabled audiences to discern new forms of meaning, pleasure, and pathos in even the most well-known material. The recordings considered here include ‘Mary Had a Little Lamb’ as well as scripts by Tennyson, Caroline Norton, Edgar Allan Poe, Shakespeare, and others. Such recitals illustrate the extent to which Edison’s talking machine influenced the reception of texts while at the same time giving rise to performances unheard of in previous cultures.

The authors include also a self-interaction of the scalar meson field and the Coulomb repulsion of the protons. The parameters of the model are constrained by the average nuclear properties. The Thomas-Fermi equations are solved numerically for finite, stable nuclei. The particular case of 208 82 Pb is considered in more detail. (Auth.)

  9. Safety Performance Improvement for Nuclear Power Plants Utilizing THOMAS

    International Nuclear Information System (INIS)

    2005-01-01

    THOMAS (Thermal Hydraulics Online Monitoring Advisory System) is equipped with a couple of salient features compared with existing monitoring systems. The first has to do with the three-dimensional (3D) visualization technique to support the nuclear power plant (NPP) operators and personnel using the virtual reality (VR) technology. VR depicts an environment simulated by a computer. Most of the VR environments primarily include visual experiences, displayed either on a monitor or though special stereoscopic goggles. Users can often interactively manipulate a VR environment, either through standard input devices like a keyboard, or through specially designed devices like a cybergloves. Additional devices were not applied the in THOMAS. The visualized model file is brought to the VR space from the computer-aided design (CAD) tool. In the VR space, using mapping, the component color is changed with linked value of the safety variables. Operators thus can easily recognize the plant condition. This is related with the human factor engineering. The second is the function of decision making using the influence diagram logic. The influence diagram logic is based on the total probability and Bayesian theory. The accident modeling is rooted in the emergency operating procedure (EOP). The final goal of this system is, in the accident situation, to present a success path to the operator for the recovery of the NPP system. At the current developing level, the database signals THOMAS. In other words, a spectrum of system analysis codes provides the safety parameter values to the database, which are subsequently supplied to THOMAS through the network

Os níveis mais elevados de QS foram alcançados nos tratamentos com plantio direto e consórcio de gramíneas e leguminosas tropicais, devido à cobertura do solo e às elevadas adições de C e N via resíduos culturais.The soil quality (SQ evaluation is an important part of agricultural planning. It allows the identification and improvement of high-yielding management systems with characteristics of environment preservation. This study was carried out in two long-term soil management experiments (10 and 15 years in Rio Grande do Sul State, Brazil. The main objective of this study was to evaluate the effectiveness of the Soil Quality Kit (SQK developed by the Soil Quality Institute - ARS - USDA, compared to traditional soil science methods. Twelve treatments of cropping and tillage systems in a range of different tillage intensities, biomass input amounts and urea-N fertilization (0 to 144 kg ha-1 were evaluated. A native vegetation field close to each experimental area was sampled as reference treatment. The following SQ indicators: water infiltration, soil respiration, soil density, N-NO3- + N-NO2-, water aggregate stability and pH were evaluated. The correlation between the SQK and soil science methods was generally high. The highest correlation was observed with pH (r = 0.98 and the lowest for infiltration (r = 0.42. The soil management treatments were theoretically classified by crescent SQ order. The carbon pool index (CPI was obtained dividing soil organic carbon stock of each treatment by native vegetation soil organic carbon 0 to 5 cm deep. The CPI reproduces the SQ classification efficiently. Aggregate stability, soil respiration and N-NO3- + N-NO2- were the most efficient indicators at discriminating SQ.

    1973-01-01

    The author has identified the following significant results. The boundaries of application of ERTS-1 and aircraft data are established for St. Thomas harbor within which useful water quality information can be obtained. In situ physical, chemical, and biological water quality and benthic data were collected. Moored current meters were employed. Optical measurements of solar irradiance, color test panel radiance and water absorption were taken. Procedures for correlating in situ optical, biological, and chemical data with underflight aircraft I2S data and ERTS-1 MSS scanner data are presented. Comparison of bulk and precision CCT computer printout data for this application is made, and a simple method for geometrically locating bulk data individual pixels based on land-water interface is described. ERTS spacecraft data and I2S aircraft imagery are correlated with optical in situ measurements of the harbor water, with the aircraft green photographic and ERTS-1 MSS-4 bands being the most useful. The biological pigments correlate inversely with the optical data for inshore areas and directly further seaward. Automated computer data processing facilitated analysis.

  6. Cholera in Thomas Mann's Death in Venice.

    Science.gov (United States)

    Rütten, Thomas

    2009-01-01

    The article sets the cholera motif in Thomas Mann's famous novella Death in Venice against the historical context from which it partially originates. It is shown that this motif, while undoubtedly appropriated to serve Mann's own poetic ends, has a solid grounding in historical and autobiographical fact, thus blurring the boundaries between fact and fiction. The article illustrates the verifiable events of the outbreak of the Venetian cholera epidemic in May 1911, which Mann partly witnessed himself, during a holiday trip to Brioni and Venice, and partly heard and read about. It is established that Thomas Mann's account of the cholera in Venice in his novella is characterised by a rare and almost preternatural insightfulness into an otherwise murky affair that was marked by rumours, speculations and denials.

    2007-12-01

    The astronomy community lost a good friend when Tom Metcalf was killed in a skiing accident on Saturday, 7 July 2007, in the mountains near Boulder, Colorado. Tom was widely known for prolific work on solar magnetic fields, hard-X-ray imaging of solar flares, and spectral line diagnostics. He was often characterized as "one of the nicest guys in science." Born October 5, 1961 in Cheverly, Maryland, to Fred and Marilyn, Thomas R. Metcalf joined his sister, Karen, two years his elder, in a close family that loved sailing, inquisitiveness, and the natural world. Sibling rivalry (usually a Tonka truck intruding on Barbie's sub-table "castle") melted when Tom and Karen collaborated on elaborately engineered room-sized blanket-forts. Tom confidently signed up at age of three to crew for his family's sailboat; when the family moved to California in 1966, as Tom's father took a Professor of Mathematics position at the University of California Riverside, Tom's love for sailing was well-established. Week-long cruises or short trips in the harbor were all fun; when school friends came aboard, it was even better--if "only slightly too crowded" from the adults' points of view. Tom's introduction to astronomy began one cold, very clear, December night in the early 1970s, on a family camping trip to Death Valley. The "Sidewalk Astronomers of San Francisco" had lined the sidewalk near the visitors' center with all sorts of telescopes for public viewing. Soon after, Tom and his boyhood friend Jim O'Linger were building their own scopes, attending "Amateur Telescope Makers" conferences, and Tom was setting up his scope on a sidewalk for public viewing. In 1986, Tom set up his telescope on the bluffs above Dana Point Harbor, and gave numerous strangers a stunning view of Halley's Comet. His interest in physics and mathematics became evident during Tom's last years in high school (Poly High in Riverside), and as a senior he qualified to take freshman Physics at the University of

    2018-03-01

    To report our experience with solo-surgeon, single-port laparoscopic anterior resection (solo SPAR) for sigmoid colon cancer. Data from sigmoid colon cancer patients who underwent anterior resections (ARs) using the single-port, solo surgery technique (n = 31) or the conventional single-port laparoscopic technique (n = 45), between January 2011 and July 2016, were retrospectively analyzed. In the solo surgeries, making the transumbilical incision into the peritoneal cavity was facilitated through the use of a self-retaining retractor system. After establishing a single port through the umbilicus, an adjustable mechanical camera holder replaced the human scope assistant. Patient and tumor characteristics and operative, pathologic, and postoperative outcomes were compared. The operative times and estimated blood losses were similar for the patients in both treatment groups. In addition, most of the postoperative variables were comparable between the two groups, including postoperative complications and hospital stays. In the solo SPAR group, comparable lymph nodes were attained, and sufficient proximal and distal cut margins were obtained. The difference in the proximal cut margin significantly favored the solo SPAR, compared with the conventional AR group (P = .000). This study shows that solo SPAR, using a passive camera system, is safe and feasible for use in sigmoid colon cancer surgery, if performed by an experienced laparoscopic surgeon. In addition to reducing the need for a surgical assistant, the oncologic requirements, including adequate margins and sufficient lymph node harvesting, could be fulfilled. Further evaluations, including prospective randomized studies, are warranted.

  16. Solo status and self-construal: being distinctive influences racial self-construal and performance apprehension in African American women.

    Sekaquaptewa, Denise; Waldman, Andrew; Thompson, Mischa

    2007-10-01

    A preliminary study and main experiment tested the hypothesis that racial solo status (being the only member of one's race in a group) increases racial self-construal among African Americans. The preliminary study showed that African American men and women reported greater collectivist (i.e., group-based) over individualist self-construal under solo compared to nonsolo status, whereas Whites did not. The main experiment showed that the increased collectivism among African American solo women appears to be strongly reflected in racial identity becoming a salient aspect of self-construal. African American participants were also more likely than Whites to perceive that their anticipated performance would be generalized to their race, to feel like representatives of their race, and to show greater performance apprehension (indirectly evidenced by increased self-handicapping) when in racial solo status. The implications of solo status for African Americans in evaluative situations (such as academic testing sessions) are discussed. 2007 APA

    Full Text Available Para estudar o efeito de doses crescentes de nitrogênio, fósforo e potássio sôbre a produção da soja em solo derivado do arenito Botucatu, com vegetação de campo cerrado, foram instalados, em 1961-62, dois ensaios fatoriais em áreas vizinhas, uma das quais recebeu calcário dolomítico. Nos canteiros do último ensaio, semeou-se feijão em 1962-63, para verificar o efeito residual dos adubos aplicados na soja. As respostas ao nitrogênio e ao potássio, bem como as interações, não foram significativas. O efeito do fósforo, porém, foi significativo e linear, tanto na cultura da soja como na do feijão. Conquanto grande nas duas áreas, êsse efeito foi muito maior naquela que recebeu prévia calagem. Comparando os resultados dos dois ensaios, verificou-se que o efeito do calcário só se tornou grande na presença do fósforo. Na área com calcário a produção de soja, em média dos tratamentos que receberam 120 kg/ha de P2O5, atingiu cêrca de 1.800 kg/ha, equiparando-se às obtidas, no Estado de São Paulo, em terras consideradas férteis.In this paper are reported the results of two factorial experiments on poor soil derived from the Botucatu sandstone, to study the effects of three levels of nitrogen, phosphorus, and potassium on the yields of soybeans. The experiments were located in neighboring areas, one of which was previously limed with dolomitic lime. The plots of the latter were sown with dry beans in the following year, to study the residual effect of the fertilizers applied to the soybeans. The responses to nitrogen and potassium, as well as the interactions, were insignificant. The effect of phosphorus, however, was significant and linear with both crops. Although high in the two areas, this effect was much higher in the limed one. Comparing the results of the two experiments, it was concluded that the response to lime was negligible in absence of phosphorus but increased considerably in its presence. On the limed

    Thomas J. Ahrens, a leader in the use of shock waves to study planetary interiors and impact phenomena, died at his home in Pasadena, California on November 24, 2010, at the age of 74. He was the California Institute of Technology's Fletcher Jones Professor of Geophysics, formally emeritus since 2005 but professionally active to the end. Tom was a pioneer in experimental and numerical studies of the effects of hypervelocity impact, arguably the most important geophysical process in the formation, growth and - in many cases - surface evolution of planets. As a professor at Caltech, he established the foremost university laboratory for shock wave experiments, where students and research associates from around the world pursued basic research in geophysics, planetary science and other disciplines. Previously, high-pressure shock experiments were primarily conducted in national laboratories, where they were initially associated with development of nuclear weapons. The shock wave laboratory at Caltech was noted for key measurements addressing major questions in planetary geophysics. Equation-of-state studies on silicate melts showed that magma deep in Earth's mantle could be denser than the coexisting crystals, implying downward transport of melts (and associated heat) rather than the upward eruption of lavas observed in volcanic regions at Earth's surface. Shock-melting experiments on iron at pressures of Earth's core provide a crucial constraint on the temperature at the center of our planet. And studies of hydrous, carbonate and sulphate minerals under shock compression document how climate-altering molecules can be released by major impacts, such as the K/T event associated with the most recent mass extinction of biota in Earth history. In addition, Tom was a leader in numerical simulation of cratering, bringing the most recent laboratory measurements into the modeling of planetary impacts. Tom's training was in geophysics and applied experimental physics, as

    2015-06-01

    Although recent typologies of female sexual offenders have recognized the importance of having a co-offender, the clinical characteristics of solo and co-female sexual offenders remain poorly understood. The aim of this study was to compare solo (n = 20) and co- (n = 20) female sexual offenders on a variety of clinical characteristics. It was found that although solo and co-offenders reported similar developmental experiences and psychological dispositions, differences were found in environmental niche, offense preceding, and positive factors. Specifically, solo offenders demonstrated a greater presence of personal vulnerabilities including mental health and substance abuse difficulties. Co-offenders reported a greater presence of environmentally based factors, including a current partner who was a known sex offender and involvement with antisocial peers. It is suggested that these results have implications for understanding assessment and intervention needs for these groups of sexual offenders. © The Author(s) 2014.

    Thomas Szasz's original critique of the concept of 'mental illness' is almost 50 years old. Over that half century Szasz has maintained a consistent campaign against the 'Therapeutic State', challenging the paternalism of coercive psychiatry and defending liberty and autonomy. Despite his widespread celebrity Szasz continues to be misread and misrepresented. In this paper we review some of Szasz's key ideas, in the light of Clarke's recent critique, setting this within the context of 'mental health nursing' and the problems in living affecting persons worldwide.

    Data on the distribution of reduced partial neutron widths and on the distribution of total gamma decay widths disagree with the Porter-Thomas distribution (PTD) for reduced partial widths or with predictions of the statistical model. We recall why the disagreement is important: The PTD is a direct consequence of the orthogonal invariance of the Gaussian Orthogonal Ensemble (GOE) of random matrices. The disagreement is reviewed. Two possible causes for violation of orthogonal invariance of the GOE are discussed, and their consequences explored. The disagreement of the distribution of total gamma decay widths with theoretical predictions cannot be blamed on the statistical model.

    Full Text Available I am delighted to be invited to attend upon this launch of the International Review of Law, conceived and now delivered into the world by the College of Law of the University of Qatar under Dr. Jon Truby’s leadership. This new and most welcome contribution to global academic writing and contemporary legal criticism, should be of the greatest interest outside Qatar, if only for its provenance. The State of Qatar has become widely known and respected for its vision, its progressive outlook, and its determination to look beyond Arab culture and traditions for new ways of working with the rest of the world for the good of the region as a whole. It has made a bold commitment to engage with the accepted legal principles and processes that have served the needs of global mercantile and commercial activity so well over the last two centuries. his is demonstrated by the generous support given by His Highness the Emir to the Qatar Law Forum 2009, to be repeated in May this year, in which jurists and lawyers of great eminence are brought together in Doha to expound, explain and exchange ideas upon the importance of the rule of law, the universal key to principled and effective government, and the protection of individual freedom and dignity. One may also cite the recently established Civil and Commercial Court, served by appointed judges of international repute from many jurisdictions, that has opened its doors in Doha for dispute resolution and adjudication. I am privileged to chair the Regulatory Tribunal, an independent statuy body composed of lawyers from overseas with specialist experience in market regulation, to which incoming investors can appeal any disputes they make with Qatar Financial Centre (QFC Institutions such as the QFC Regulatory Authority and QFC Authority In the same way, the founding of Qatar University College of Law in 2006 has shown Qatar’s determination to train future generations of Qataris to build on the best of legal

    Full Text Available Para estudar o efeito da aplicação de nitrogênio, fósforo, potássio e calcário na cultura do milho em solo da série Tumirim, realizaram-se três experiências em São José dos Campos. O calcário foi aplicado a lanço; os adubos, nos sulcos de plantio. Como numa das experiências o coeficiente de variação foi elevado, as conclusões se baseiam principalmente nos resultados das outras duas. Em nenhum caso o nitrogênio aumentou a produção o o efeito médio do potássio foi muito pequeno. Para isso parece terem concorrido a utilização de áreas que estiveram como pastagem por muitos anos, a elevada acidez dos solos, o modo de aplicação dos adubos e o emprêgo do nitrogênio na forma amoniacal. Entretanto, o efeito do fósforo foi grande, sendo que a presença do calcário exalçou o das suas maiores doses. Quanto ao do calcário, foi satisfatório na presença de quantidades elevadas de fósforo, mas nulo ou negativo na de doses moderadas dêsse elemento ou na sua ausência.Three experiments were conducted at São José dos Campos, State of São Paulo, in an area of the Tumirim soil series, to study the effects of nitrogen, phosphorus, potassium, and lime on the corn crop. As one of the trials showed a high variation coefficient, the conclusions are mainly based on the results of the other two. Nitrogen did not increase the yields and the effect of potash was wery small. These results are perhaps due to the location of the trials in areas fallowed for a long time, the strong acidity of the soils, the placement of the fertilizers in contact with the seed, and the use of ammonia-N. The effect of phosphorus was high, and the presence of lime enhanced that of its larger rates of application. As for lime, its effect was satisfactory in the presence of the higher quantities of phosphorus but none or negative in the presence of moderate rates of that nutrient or in its absence.

    The Bo (meaning 'ox' in the Venetian dialect) is the historic seat of the University of Padua, founded in 1222. A full-length portrait of Thomas Linacre stands in its prestigious Sala dei Quaranta (Hall of the Forty), so called because of the portraits of forty great foreign scholars of the University, painted by Giacomo dal Forno in 1942. Thomas Linacre came to Italy in 1485, following an embassy by Henry VII to the Vatican. Linacre visited Bologna, Florence, Rome, Venice, Vicenza and Padua, where he took his degree in medicine in 1496 with great distinction. During his stay in Italy he met illustrious humanists and physicians, including Poliziano, Hermolaus Barbarus and Aldus Manutius Romanus, and Nicolaus Leonicenus who further stimulated him to the translation of classic works by Hippocrates and Galen. In 1518 Linacre played a pivotal role in the foundation of the Royal College of Physicians in London which, as first President, he organized on the basis of Italian models. With his portrait, the University of Padua celebrates the life and work of an astonishing figure linking the Italian and English medical cultures.

  11. Temporal changes on the effect of rock fragments in interrill soil loss: a simulation experiment and a simple descriptive model Variação temporal do efeito da cobertura pedregosa na perda de solo por erosão interssulcos: simulação experimental e modelo descritivo

    Full Text Available Soils with rock fragments have been studied under several aspects in the last years. Research shows that a single pattern in the erosional response of these soils to rainfalls is not always found. In order to contribute to the understanding of this topic, an experiment was carried out, simulating interrill areas covered by rock fragments. This paper specifically aims at presenting and discussing temporal changes on sediment exported from such areas, also introducing a simple descriptive model to represent soil loss temporal evolution. Small bottom perforated boxes, 612 cm² area, were filled with a silt-loam fine earth, very poor in organic matter, covered with simulated rock fragments and leaned at 10% slope gradient. The experiment comprised the exposure to 240 mm natural rainfall of 48 boxes corresponding to selected combinations, 4 replicates each, of rock fragments cover (0, 17, 30 and 66%, size (2, 4 and 10 cm, form (rectangular and circular and position (resting on top and embedded. During the experiment boxes were kept under near saturation soil water conditions. Water and soil exported from the boxes as infiltration, runoff, wash and splash were measured after each period of precipitation. Recorded values of soil loss plotted against precipitation, both expressed in cumulative terms, follow a sigmoid curve. This pattern of response was interpreted as a result of crust formation on soil surface exposed to rainfalls, a hypothesis suggested by observations during the experiment and confirmed at its end. Parameters of this model were related with rock cover and characteristics. The effect of rock fragments on soil loss varies with time, a conclusion that must be taken into account when interpreting either results from experiments with different durations or the evolution of stoniness on eroding surfaces.Os solos pedregosos vêm sendo estudados sob diversos aspectos nos últimos anos.

    Thomas K. Jeffers has made many significant contributions to our understanding of the biology of the parasite Eimeria, the cause of coccidiosis in poultry. His work has had direct practical application for the control of this widespread disease. Topics discussed include Jeffers' pioneering work concerned with genetics of the host response to infection, the nature of biological and immunological intraspecific variation, drug resistance and discovery, field surveys of resistance, and his most recognized achievement-the demonstration that the lifecycle of coccidia may be altered by artificial selection. Parasites so modified are attenuated but retain their immunogenicity, a discovery that has led to the development of live vaccines that are inherently non-pathogenic. This article provides a brief biography and describes the contributions that Jeffers has made to our knowledge of coccidiosis.

    Thomas Schwencke (1694-1767) was Professor of Anatomy and Surgery and Lecturer in Obstetrics at the Surgical School in The Hague, the Netherlands. In 1743 he published the very first textbook on haematology. Furthermore, he described his observations on the variolation of smallpox, and published the design of a new obstetric instrument. Schwencke was physician of the city of The Hague and also physician at the court of the princes van Nassau-Weilburg. In 1765 Princess Caroline of Nassau-Weilburg invited the young Wolfgang Amadeus Mozart to perform concerts. During his Dutch tour the young Mozart fell seriously ill, probably from typhoid fever. At the request of the court Mozart was seen for a second opinion and thereafter successfully treated by Schwencke. Mozart could continue his concert tour and Schwencke's reputation as Mozart's physician was established.

    A wealth of different expressions for the frequency of the Thomas precession (TP) can be found in the literature, with the consequence that this issue has been discussed over a long period of time. It is shown that the correct result was obtained in the works of several authors, which were published more than forty years ago but remained unnoticed against the background of numerous erroneous works. Several TP-related physical paradoxes formulated primarily to disprove the special relativity theory are shown to be fallacious. Different techniques for deriving the correct expression are considered and the reasons for the emergence of the main incorrect expressions for the TP frequency are analyzed.

    Studies have highlighted differences in the victim choice, offender, and offense characteristics of female and male sexual offenders. However, little is known about how solo and co-offending females differ from solo male sexual offenders. We compared the characteristics of 20 solo and 20 co-offending females (co-offended with a male and/or female accomplice), and 40 male sexual offenders against children. We found that solo female offenders showed the most evidence of personal problems, including depression and sexual dissatisfaction. Compared with male offenders, female co-offenders showed poorer self-management, but better sexual self-regulation. Male offenders had a greater history of offending and showed more evidence of sexual abuse supportive cognitions relative to both solo and co-offending females. These results are consistent with the need for a gender-specific approach to working with sexual offenders and may have implications for understanding the often complex treatment needs of these clients.

    Changes in health care are having a dramatic effect on the practice of medicine. In 2005, a National Center for Health Statistics survey showed that 55%-70% of physicians are in small/solo practices. These data also demonstrated that 70% of physicians identified themselves as owners. Since passage of the Affordable Care Act (ACA) in 2010, neurologists report an 8% increase in academic practice settings, a 2% decrease in private practice settings, and a 5% decrease in solo practice settings. Surveys of family physicians showed that 60% are now employees of hospitals or larger groups. A survey by The Physicians Foundation showed that 89% of physicians believed that the traditional model of independent private practice is either "on shaky ground" or "a dinosaur soon to go extinct." With the changes expected from the ACA, solo/small practices will continue to face challenges and therefore must pay close attention to business and clinical metrics.

  10. Thomas Piketty’s capitalism revisited

    Directory of Open Access Journals (Sweden)

    Milovanović Milić

    2015-01-01

    Full Text Available Thomas Piketty’s international best selling Capital in the Twenty-First Century lays out his theory of a long-run rise in income inequality under capitalism. It is written as a manifesto urging reintegration of social sciences. A number of reviewers judged it on ideological grounds, labeling it either as a revolution in economic thinking, or dismissing it offhandedly. Piketty’s theory of rising inequality is based on the two Fundamental Laws of Capitalism, developed after the Solow growth model. However, this model is inconsistent with Piketty’s own characterization of modern capitalism. Moreover, his sole justification for the constant discrepancy between rate of return and rate of income growth (r > g is based on the high elasticity of substitution between capital and labor. However, that is just one factor that can have an influence on factor income shares. By failing to offer a consistent theory of rising inequality, his piece can hardly be considered as a useful founding stone for a new social science.

  11. The nuclear Thomas-Fermi model

    International Nuclear Information System (INIS)

    Myers, W.D.; Swiatecki, W.J.

    1994-08-01

    The statistical Thomas-Fermi model is applied to a comprehensive survey of macroscopic nuclear properties. The model uses a Seyler-Blanchard effective nucleon-nucleon interaction, generalized by the addition of one momentum-dependent and one density-dependent term. The adjustable parameters of the interaction were fitted to shell-corrected masses of 1654 nuclei, to the diffuseness of the nuclear surface and to the measured depths of the optical model potential. With these parameters nuclear sizes are well reproduced, and only relatively minor deviations between measured and calculated fission barriers of 36 nuclei are found. The model determines the principal bulk and surface properties of nuclear matter and provides estimates for the more subtle, Droplet Model, properties. The predicted energy vs density relation for neutron matter is in striking correspondence with the 1981 theoretical estimate of Friedman and Pandharipande. Other extreme situations to which the model is applied are a study of Sn isotopes from 82 Sn to 170 Sn, and the rupture into a bubble configuration of a nucleus (constrained to spherical symmetry) which takes place when Z 2 /A exceeds about 100

    The FT 648 type portable absolute radon meter has been developed and the designing principle of this instrument is introduced. The absolute radon meter differs from relative radon meter. By using structure parameters, operating parameters and readout of this instrument, the radon content of measured gas is obtained directly without calibration in advance. Normally, the calibration is done by a standard radioactive gaseous source of which the radon concentration is known. The systematic error is removed by adding filter-efficiency Σ, α self-absorption correction β, energy spectrum correction S, geometric factor Ω of probe and gravity dropping correction factor G to the Thomas formula for radon measurement of two-filter method. The atmosphere radon content, which is given in hour-average, in Beijing area was measured by FT 648 type absolute radon meter. The measurement lasted continuously for several days and nights and a 'saddle shape' of radon content-time curve was observed. The day's average radon content was 8.5 Bq·m -3

    2016-08-01

    The aim of this study was to assess the contributions of Thomas Waters's work in the field of health care ergonomics and beyond. Waters's research of safe patient handling with a focus on reducing musculoskeletal disorders (MSDs) in health care workers contributed to current studies and prevention strategies. He worked with several groups to share his research and assist in developing safe patient handling guidelines and curriculum for nursing students and health care workers. The citations of articles that were published by Waters in health care ergonomics were evaluated for quality and themes of conclusions. Quality was assessed using the Mixed Methods Appraisal Tool and centrality to original research rating. Themes were documented by the type of population the citing articles were investigating. In total, 266 articles that referenced the top seven cited articles were evaluated. More than 95% of them were rated either medium or high quality. The important themes of these citing articles were as follows: (a) Safe patient handling is effective in reducing MSDs in health care workers. (b) Shift work has negative impact on nurses. (c) There is no safe way to manually lift a patient. (d) Nurse curriculums should contain safe patient handling. The research of Waters has contributed significantly to the health care ergonomics and beyond. His work, in combination with other pioneers in the field, has generated multiple initiatives, such as a standard safe patient-handling curriculum and safe patient-handling programs. © 2016, Human Factors and Ergonomics Society.

The other findings were the city of Solo was constructed by a-three-concept of urban design as follows: the organic concept which was conducted by native people; the colony concept which was conducted by the Dutch; and the cosmology concept which was conducted by the Javanese Kingdom. In 1500s-1750s, initially the city of Solo was a settlement grew at the bank of Bengawan Solo. Afterwards, in 1750s-1850s it developed into a combined water- and land- based urban fabric Since 1850s, the city of Solo has left the river transportation and changed into the land transportation. Moreover, in 1900s the city of Solo built the new technology of transportation and urban utilities as follows: train, tram (streetcar, electricity and water city

  19. Electron-electron Thomas peak in fast transfer ionization

    International Nuclear Information System (INIS)

    Tolmanov, S. G.; McGuire, J. H.

    2000-01-01

    ''Thomas process'' is a name used for a family of singular two-step processes that can lead to electron transfer. The Thomas process of the ''second kind,'' occurring in reactions with both transfer and ionization, utilizes the e-e scattering in the second step, so this Thomas process requires the dynamics of the electron-electron interaction. We calculate numerically the second order element of an S matrix and corresponding cross sections for the transfer ionization process. We find that the position and shape of the Thomas peak depend on both electron-electron and the electron-nucleus interaction. Also the direct and exchange amplitudes are equal at the peak position. We test the peaking approximation used for transfer ionization. Our results can be compared to experimental results for p + +He→H+He 2+ +e - . (c) 2000 The American Physical Society

    Faussurier, Gérald

    2017-11-01

    We investigate the relativistic finite-temperature Thomas-Fermi model, which has been proposed recently in an astrophysical context. Assuming a constant distribution of protons inside the nucleus of finite size avoids severe divergence of the electron density with respect to a point-like nucleus. A formula for the nuclear radius is chosen to treat any element. The relativistic finite-temperature Thomas-Fermi model matches the two asymptotic regimes, i.e., the non-relativistic and the ultra-relativistic finite-temperature Thomas-Fermi models. The equation of state is considered in detail. For each version of the finite-temperature Thomas-Fermi model, the pressure, the kinetic energy, and the entropy are calculated. The internal energy and free energy are also considered. The thermodynamic consistency of the three models is considered by working from the free energy. The virial question is also studied in the three cases as well as the relationship with the density functional theory. The relativistic finite-temperature Thomas-Fermi model is far more involved than the non-relativistic and ultra-relativistic finite-temperature Thomas-Fermi models that are very close to each other from a mathematical point of view.

    2017-01-01

    This study aimed to evaluate the feasibility and efficacy of solo-surgeon retroauricular thyroidectomy. For solo-surgery, we used an Endoeye Flex Laparo-Thoraco Videoscope (Olympus America, Inc.). A Vitom Karl Storz holding system (Karl Storz GmbH & Co.) composed of several bars connected by a ball-joint system was used for fixation of endoscope. A snake retractor and a brain-spoon retractor were used on the sternocleidomastoid. Endoscopic thyroidectomy using the solo-surgeon technique was performed in 10 patients having papillary thyroid carcinoma. The mean patient age was 36.0 ± 11.1 years, and all patients were female. There were no postoperative complications such as vocal cord paralysis and hematoma. When compared with the operating times and volume of drainage of a control group of 100 patients who underwent surgery through the conventional retroauricular approach between May 2013 and December 2015, the operating times and volume of drainage were not significantly different (P = .781 and .541, respectively). Solo-surgeon retroauricular thyroidectomy is safe and feasible when performed by a surgeon competent in endoscopic thyroidectomy.

  10. American Connections: The Early Works of Thomas Bang

    Directory of Open Access Journals (Sweden)

    Ring Petersen, Anne

    2015-09-01

    Full Text Available The Danish artist Thomas Bang spent his early years in the USA. The works he created in this formative period were thus profoundly shaped by the contemporary movements in American art of the 1960s and 1970s when sculpture, or to be more precise, three-dimensional work became a hotbed of expansive experiments. This article traces how Bang made a radical move from painting to sculpture, which was characteristic of that time, and how he developed his artistic idiom by taking an active part in some of the seminal new departures in American art, in particular process art and post-minimalism. By leaping forward to Bang's later works produced after his return to Denmark, the article also demonstrates how the sculptural syntax and working principles developed in the early works still underlie and structure the artist's more allegorical sculptures and installations from the 2000s, thus testifying to the lasting impact of Bang's American period, which remains the key to understanding his works.

    2014-04-01

    The sensational "reactome array" paper published in Science in 2009 was investigated in Spain by the Ethics Committee of Consejo Superior de Investigaciones Cientificas (CSIC) after Science issued an editorial expression of concern. The paper was retracted in 2010 because of "skepticism" due to "errors" in chemistry. The "errors" were so profound that many readers expressed doubt that they were really errors, but part of an elaborate hoax. I conducted a forensic analysis of mass spectrometry data in the paper's Supporting Online Material (SOM) and was able to prove that thousands of data values were in fact fabricated. The SOM contains signatures of improper extensive spreadsheet manipulations of incorrect atomic and molecular mass values as well as impossibly repetitive deviations of found molecular mass values from their expected values. No evidence of real mass spectrometry data was detected. Both CSIC and Science have been content to retract the paper without acknowledging the fabrications or assigning responsibility for them. Neither CSIC nor Science has expressed interest in having an independent investigation determining how the paper came to be written, reviewed and published. Their weak response to this episode is a daunting signal that there is an impending crisis in research integrity and science journalism.

    Full Text Available Nella prolusione al suo corso al Collège de France, pronunciata il 6 aprile 2006, Thomas Pavel si interroga sugli aspetti emotivi ed etici dell'attività della lettura, sull'“abbandonarsi” di chi legge all'opera letteraria. Come avviene la trasfigurazione del quotidiano nel mondo finzionale? Come si svolge il processo di identificazione dell'io nell'opera? Lo studioso rintraccia il fondamento di tale processo nella non coincidenza di principio tra io e vita, quindi nella facoltà del lettore di accogliere e riconoscere il senso dell'opera. Un senso che tuttavia non si palesa una volta per tutte nella sua interezza e trasparenza, ma che diviene oggetto di continuo dialogo fra i lettori, un senso quindi affidato alle loro cure.During the opening lecture of his course at Collège de France, held on April 6th 2006, Thomas Pavel talks about the emotional and ethical aspects of reading and about «completely surrending» to literature. How is everyday life transfigured into poetic invention? How is our ego identified in the literary work? The scholar traces the origin of this process to the radically different principles governing ego and life. Because of this, the reader is able to grasp and understand the real meaning of the book. This, however, is never completely revealed in a clear way. Instead, it becomes the object of a never-ending dialogue among the readers: it is therefore their care the meaning is entrusted to.Во вступлении к своему курсу лекций во Французском Колледже, произнесенном 6-го апреля 2006-го года, Томас Павел размышляет о эмоциональных и этических сторонах чтения, о том, как читатель «отдается» литературному произведению.

    Energy Technology Data Exchange (ETDEWEB)

    Michaud, E. C. (Nuclear Engineering Division)

    2010-01-01

    Over the years, I've daydreamed about stealing a Vermeer, a Picasso, or Rembrandt. It tickles me, as much as watching the reboot of The Thomas Crown Affair. Why is it, do you suppose, so much fun to think about stealing a world renowned piece off the wall of a major metropolitan museum? Is it the romantic thoughts of getting away with it, walking past infrared detectors, and pressure sensors ala Indiana Jones with the sack of sand to remove the idol without triggering the security system? Is it the idea of snatching items with such fantastic prices, where the romance of possessing an item of such value is less intoxicating than selling it to a private collector for it to never be seen again? I suspect others share my daydreams as they watch theater or hear of a brazen daylight heist at museums around the world, or from private collections. Though when reality sets in, the mind of the security professional kicks in. How could one do it, why would one do it, what should you do once it's done? The main issue a thief confronts when acquiring unique goods is how to process or fence them. They become very difficult to sell because they are one-of-a-kind, easy to identify, and could lead to the people involved with the theft. The whole issue of museum security takes up an ironic twist when one considers the secretive British street artist 'Banksy'. Banksy has made a name for himself by brazenly putting up interesting pieces of art in broad daylight (though many critics don't consider his work to be art) on building walls, rooftops, or even museums. I bring him up for a interesting take on what may become a trend in museum security. In March of 2005, Banksy snuck a piece of his called 'Vandalized Oil Painting' into the Brooklyn Museum's Great Historical Painting Wing, plus 3 other pieces into major museums in New York. Within several days, 2 paintings had been torn down, but 2 stayed up much longer. In his home country of the UK, a

    Physiological changes during pregnancy affect routine tests for iron deficiency. The reticulocyte haemoglobin equivalent (RET-He) and serum-soluble transferrin receptor (sTfR) assay are newer diagnostic parameters for the detection of iron deficiency, combined in the Thomas diagnostic plot. We used this plot to determine the iron status of pregnant women presenting for their first visit to an antenatal clinic in Bloemfontein, South Africa. Routine laboratory tests (serum ferritin, full blood count and C-reactive protein) and RET-He and sTfR were performed. The iron status was determined using the Thomas plot. For this study, 103 pregnant women were recruited. According to the Thomas plot, 72.8% of the participants had normal iron stores and erythropoiesis. Iron-deficient erythropoiesis was detected in 12.6%. A third of participants were anaemic. Serum ferritin showed excellent sensitivity but poor specificity for detecting depleted iron stores. HIV status had no influence on the iron status of the participants. Our findings reiterate that causes other than iron deficiency should be considered in anaemic individuals. When compared with the Thomas plot, a low serum ferritin is a sensitive but nonspecific indicator of iron deficiency. The Thomas plot may provide useful information to identify pregnant individuals in whom haematologic parameters indicate limited iron availability for erythropoiesis. © 2015 John Wiley & Sons Ltd.

    Vivien Thomas (1910-1985) was an African-American scientist, pioneer, and renowned educator. Thomas's contributions to cardiovascular surgery were unequivocal, and yet it was only after his death that he gained more widespread recognition. Thomas's more notable work involves aiding in the discovery of the cause of traumatic shock, designing and guiding the first operation to treat Tetralogy of Fallot, carrying out the first atrial septectomy, and helping develop the electrical defibrillator. Thomas struggled amidst the adversities of racism and the Great Depression (1929-1941), armed merely with a high school degree. Nevertheless, his genius and determination eventually led him to receive an honorary doctorate from John Hopkins University. His story inspired the creation of the award winning PBS documentary in 2003 Partners of the Heart and also the 2004 Emmy Award-winning HBO film Something the Lord Made. This article will aim to provide an overview to the more notable events in Thomas's amazing tale, with a particular focus on his work on the Tetralogy of Fallot.

    2004-12-01

    Thomas M. Donahue, one of the nation's leading space and planetary scientists and a pioneer of space exploration, died Saturday October 16, 2004, from complications following heart surgery. The Edward H. White II Distinguished University Professor of Planetary Science at the University of Michigan, Tom shaped space exploration through his scientific achievements and policy positions. His work started with the first use of sounding rockets following World War II and continued for almost 60 years. Tom was born in Healdton, Oklahoma on May 23, 1921 to Robert Emmet and Mary (Lyndon) Donahue. His father was a plumber in the oil fields when Tom was born (Healdton OK was an oil town) and worked as a plumber in Kansas City for a time. Tom grew up in Kansas City, graduating in 1942 from Rockhurst College in that city with degrees in classics and physics. His graduate work in physics at Johns Hopkins University was interrupted by service in the Army Signal Corps. He obtained his PhD degree in atomic physics from Hopkins in the fall of 1947. After three years as a post-doctoral research associate and assistant professor at Hopkins, Tom joined the University of Pittsburgh Physics Department in 1951. At Pittsburgh he organized an atomic physics and atmospheric science program that led to experimental and theoretical studies of the upper atmosphere of the Earth and other solar system planets with instruments flown on sounding rockets and spacecraft. He became Professor of Physics in 1959 and eventually Director of the Laboratory for Atmospheric and Space Sciences and the Space Research Coordination Center at the University. In 1960 he spent a sabbatical year on a Guggenheim Fellowship at the Service d'Aeronomie in Paris, which began collaborations with French colleagues that flourished for more than 40 years. In 1974 he became the Chairman of the Atmospheric and Oceanic Science Department, University of Michigan, a position he held until 1981. In 1986, he was named the Henry

    Two corrections to the Thomas-Fermi theory of atoms are studied. First the correction for exchange, that is the effect of the Pauli principle in the interaction energy, is considered. The defining variational problem is non-convex and standard technique to prove existence of a minimizing solution do not apply. Existence and uniqueness of solutions are established by convexifying or relaxing the energy functional. Properties of the minimizing solution are studied. A second correction due to von Weizsaecker is also discussed. Finally the dual principle to the Thomas-Fermi variational problem is studied (only in the neutral case). A dual principle is suggested for the ionic case. Also, a review of recent rigorous results concerning Thomas-Fermi theory is presented

  3. Thomas Henry Huxley et la Bible Thomas Henry Huxley and the Bible

    Directory of Open Access Journals (Sweden)

    2009-10-01

    Full Text Available Thomas Henry Huxley devoted several essays to the study of the Bible. This interest can only be accounted for if his ideas on history, religion as well as epistemology are examined. According to him, a struggle between free thought and supernaturalism was culminating during the Victorian era, hence the need for a “New Reformation” which was heir to the ideals of freedom defended by the humanists of the Renaissance. This movement opposed the principles of the supporters of what he called “ecclesiasticism”. The advocates of the “New Reformation” could rely on the progress of modern science, and agnosticism, which Huxley identified with scientific method, became its epistemological foundation. As a result, Huxley thought that the authority of physical science was in conflict with the infallibility of the Scriptures and with the theological arguments which rested on it, and this notably led him to the conclusion that the biblical narrative of the Flood was unhistorical. The naturalisation of the Scriptures seems then logically to follow his philosophical views based on the limits of human knowledge.It appears that it was the question of authority which underlay Huxley’s interest in the Bible. He thought that the authority of the Scriptures must be replaced by that of science.

    We show that the partition functions which enumerate Donaldson-Thomas invariants of local toric Calabi-Yau threefolds without compact divisors can be expressed in terms of specializations of the Schur measure. We also discuss the relevance of the Hall-Littlewood and Jack measures in the context of BPS state counting and study the partition functions at arbitrary points of the Kaehler moduli space. This rewriting in terms of symmetric functions leads to a unitary one-matrix model representation for Donaldson-Thomas theory. We describe explicitly how this result is related to the unitary matrix model description of Chern-Simons gauge theory. This representation is used to show that the generating functions for Donaldson-Thomas invariants are related to tau-functions of the integrable Toda and Toeplitz lattice hierarchies. The matrix model also leads to an interpretation of Donaldson-Thomas theory in terms of non-intersecting paths in the lock-step model of vicious walkers. We further show that these generating functions can be interpreted as normalization constants of a corner growth/last-passage stochastic model.

    We show that the partition functions which enumerate Donaldson-Thomas invariants of local toric Calabi-Yau threefolds without compact divisors can be expressed in terms of specializations of the Schur measure. We also discuss the relevance of the Hall-Littlewood and Jack measures in the context of BPS state counting and study the partition functions at arbitrary points of the Kähler moduli space.

    In the Thomas-Fermi approximation to theories of coupled fermions and scalars, the equations for spherically-symmetric non-topological solitons have the form of potential motion. This gives a straightforward method for proving the existence of non-topological solitons in a given theory and for finding the constant-density, saturating solutions

  8. Obituary: Thomas Gold, 1920-2004

    Dermott, Stanley F.

    2004-12-01

    Thomas "Tommy" Gold died of heart disease at Cayuga Medical Center, Ithaca NY on 22 June 2004 at the age of 84. He will be remembered as one of the most interesting, dynamic and influential scientists of his generation. Tommy's paradigm-changing ideas in astronomy and planetary science, while original and bold, were also highly controversial. With his radical work on the origin of natural gas and petroleum, the controversy is likely to continue. Tommy was born in Vienna, Austria on 22 May 1920, moving with his family to Berlin at age 10 and then, after the rise of Hitler in 1933, to England. His parents were Josephine (nee Martin) and Maximillian Gold, a successful steel magnate. Tommy was educated at Zuoz College in Switzerland where he became an expert skier and developed an athletic prowess that he maintained throughout his life, winning a NASTAR gold medal for skiing at the age of 65. He studied Mechanical Sciences at Trinity College, Cambridge, but much to his disgust his education was interrupted because of internment by the British as a suspected enemy alien. That unfortunate period (I remember him saying to me "Can you believe the stupidity, interring people like me who had fled from Nazi Germany?") had one good outcome: on his first night in camp he met Hermann Bondi who had an important influence on his early development as a scientist. They were both born in Vienna, their parents knew each other, and they were fellow students at Trinity, but this was their first meeting. On release, he went immediately into top-secret radar research for the British Admiralty, working as a team with Bondi and Fred Hoyle in a farm cottage in Dunsfold, Surrey. Tommy's first published research, which was a Nature paper with R.J. Pumphrey in 1947, was not in astronomy but physiology. He applied his engineer's understanding of positive feedback to develop and test a resonance model for how the human ear determines pitch. His conclusion that pitch discrimination occurs

  11. "Ring" in the solo child singing voice.

    Science.gov (United States)

    Howard, David M; Williams, Jenevora; Herbst, Christian T

    2014-03-01

    Listeners often describe the voices of solo child singers as being "pure" or "clear"; these terms would suggest that the voice is not only pleasant but also clearly audible. The audibility or clarity could be attributed to the presence of high-frequency partials in the sound: a "brightness" or "ring." This article aims to investigate spectrally the acoustic nature of this ring phenomenon in children's solo voices, and in particular, relating it to their "nonring" production. Additionally, this is set in the context of establishing to what extent, if any, the spectral characteristics of ring are shared with those of the singer's formant cluster associated with professional adult opera singers in the 2.5-3.5kHz region. A group of child solo singers, acknowledged as outstanding by a singing teacher who specializes in teaching professional child singers, were recorded in a major UK concert hall performing Come unto him, all ye that labour, from the aria He shall feed his flock from The Messiah by GF Handel. Their singing was accompanied by a recording of a piano played through in-ear headphones. Sound pressure recordings were made from well within the critical distance in the hall. The singers were observed to produce notes with and without ring, and these recordings were analyzed in the frequency domain to investigate their spectra. The results indicate that there is evidence to suggest that ring in child solo singers is carried in two areas of the output spectrum: first in the singer's formant cluster region, centered around 4kHz, which is more than 1000Hz higher than what is observed in adults; and second in the region around 7.5-11kHz where a significant strengthening of harmonic presence is observed. A perceptual test has been carried out demonstrating that 94% of 62 listeners label a synthesized version of the calculated overall average ring spectrum for all subjects as having ring when compared with a synthesized version of the calculated overall average nonring

    Full Text Available O objetivo deste trabalho foi avaliar a relação entre a estrutura anatômica das raízes de milho e os atributos físicos de solo submetido a diferentes graus de compactação. O estudo foi realizado em campo, no Município de Dourados, MS, em Latossolo Vermelho distroférrico, textura muito argilosa. O delineamento experimental foi o de blocos ao acaso, com cinco repetições. O solo utilizado apresentava histórico de oito anos com plantio direto. A compactação adicional do solo foi realizada por meio de tráfego com trator, com uma (PDc1, duas (PDc2, quatro (PDc4 e seis passadas (PDc6 sucessivas, sobre toda a área da parcela. Houve aumento na razão entre o córtex e o cilindro vascular da raiz com o aumento na compactação do solo. Essa razão correlacionou-se negativamente com a macroporosidade e positivamente com a densidade do solo e com a resistência do solo à penetração. O grau de compactação afeta a anatomia radicular do milho, e a resistência do solo à penetração é o indicador físico que melhor expressa esse efeito.The objective of this work was to evaluate the relationship between maize root anatomy and physical attributes of soil subjected to levels of compaction. The experiment was carried out in field conditions, in Dourados, Mato Grosso do Sul state, Brazil, in a clayed Latossolo Vermelho (Rhodic Acrustox. A randomized complete block design was used, with five replicates. The soil was cultivated for eight years under no-tillage. The additional compaction of the soil was done by tractor traffic in one (PDc1, two (PDc2, four (PDc4 and six successive passes (PDc6, in the entire area of the experimental plots. Ratio between the cortex and vascular cylinder of the root increased with soil compaction. This ratio was negatively correlated to macroporosity, and positively to soil density and soil penetration resistance. Soil compaction level affects the anatomy of maize roots, and its penetration resistance is the best

    Advancement in both surgical technique and medical equipment has enabled solo surgery. ViKY ® Endoscope Positioning System (ViKY ® ) is a robotic system that remotely controls an endoscope and provides direct vision control to the surgeon. Here, we report our experience with ViKY ® -assisted solo surgery. We retrospectively examined 25 cases of solo surgery TAPP with ViKY ® . ViKY ® was setup by the surgeon alone, and the setup duration was determined as the time at which the side rail was positioned and that when the endoscope was installed. For assessing the control unit, the number of false movements was counted. We compared the operative results between ViKY ® -assisted solo surgery TAPP and the conventional method with an assistant. The average time to set up ViKY ® was 7.9 min. The average number of commands for ViKY ® during surgery was 98.3, and the average number of errors and no response of control unit was 7.9. The mean duration of surgery was 136 min for the ViKY ® group, including the setup time, and 117 min for the conventional method. No case required an assistant during the operation. There was also no difference between the two groups with regard to postoperative complications and the rate of recurrence. ViKY ® proved reliable in recognizing orders with very few failures, and the operations were performed safely and were comparable to the conventional operations with assistants. Solo surgery with ViKY ® was beneficial in this clinical evaluation.

    Disclosure of donor conception to children was compared between solo mother and two-parent families with children aged 4-8 years conceived since the removal of donor anonymity in the UK. Semi-structured interviews were conducted with 31 heterosexual solo mothers and 47 heterosexual mothers with partners to investigate their decisions and experiences about identifiable donation and disclosure to their children. No significant difference was found in the proportion of mothers in each family type who had told their children about their donor conception (solo mothers 54.8%; partnered mothers 36.2%). Of those who had not told, a significantly higher proportion of solo mothers than partnered mothers intended to disclose (P parents will tell their children about their origins or their entitlement to request the identity of their donor at the age of 18 years. Further qualitative research would increase understanding of solo mothers' attitudes towards disclosure. Copyright © 2016 The Authors. Published by Elsevier Ltd.. All rights reserved.

  3. Duet function in the yellow-naped amazon, Amazona auropalliata: evidence from playbacks of duets and solos.

    Dahlin, Christine R; Wright, Timothy F

    2012-01-01

    The question of why animals participate in duets is an intriguing one, as many such displays appear to be more costly to produce than individual signals. Mated pairs of yellow-naped amazons, Amazona auropalliata, give duets on their nesting territories. We investigated the function of those duets with a playback experiment. We tested two hypotheses for the function of those duets: the joint territory defense hypothesis and the mate-guarding hypothesis, by presenting territorial pairs with three types of playback treatments: duets, male solos, and female solos. The joint territory defense hypothesis suggests that individuals engage in duets because they appear more threatening than solos and are thus more effective for the establishment, maintenance and/or defense of territories. It predicts that pairs will be coordinated in their response (pair members approach speakers and vocalize together) and will either respond more strongly (more calls and/or more movement) to duet treatments than to solo treatments, or respond equally to all treatments. Alternatively, the mate-guarding hypothesis suggests that individuals participate in duets because they allow them to acoustically guard their mate, and predicts uncoordinated responses by pairs, with weak responses to duet treatments and stronger responses by individuals to solos produced by the same sex. Yellow-naped amazon pairs responded to all treatments in an equivalently aggressive and coordinated manner by rapidly approaching speakers and vocalizing more. These responses generally support the joint territory defense hypothesis and further suggest that all intruders are viewed as a threat by resident pairs.

  4. Choir versus Solo Singing: Effects on Mood, and Salivary Oxytocin and Cortisol Concentrations.

    2017-01-01

    The quantification of salivary oxytocin (OXT) concentrations emerges as a helpful tool to assess peripheral OXT secretion at baseline and after various challenges in healthy and clinical populations. Both positive social interactions and stress are known to induce OXT secretion, but the relative influence of either of these triggers is not well delineated. Choir singing is an activity known to improve mood and to induce feelings of social closeness, and may therefore be used to investigate the effects of positive social experiences on OXT system activity. We quantified mood and salivary OXT and cortisol (CORT) concentrations before, during, and after both choir and solo singing performed in a randomized order in the same participants (repeated measures). Happiness was increased, and worry and sadness as well as salivary CORT concentrations were reduced, after both choir and solo singing. Surprisingly, salivary OXT concentrations were significantly reduced after choir singing, but did not change in response to solo singing. Salivary OXT concentrations showed high intra-individual stability, whereas salivary CORT concentrations fluctuated between days within participants. The present data indicate that the social experience of choir singing does not induce peripheral OXT secretion, as indicated by unchanged salivary OXT levels. Rather, the reduction of stress/arousal experienced during choir singing may lead to an inhibition of peripheral OXT secretion. These data are important for the interpretation of future reports on salivary OXT concentrations, and emphasize the need to strictly control for stress/arousal when designing similar experiments.

    We compare the Bakamjian-Thomas (BT) formulation of relativistic few-body systems with light-front field theories that maintain closer contact with Feynman diagrams. We find that Feynman diagrams distinguish Melosh rotations and other kinematical quantities belonging to various composite subsystem frames that correspond to different loop integrals. The BT formalism knows only the rest frame of the whole composite system, where everything is evaluated. (author)

    Affective and cognitive image are two main factors that influence destination in Solo. The purpose of this research is to examine the two main factors of Solo towards tourist attraction. The research method is quantitative. Data collected from observation and survey. A total of 113 respondents obtained from accidental sampling method. The results indicate based on cognitive and affective image. Cognitive consists of culture, batik, city tagline, and community. While, affective consists of tradition, culinary, purposes, climate, and welcoming. The findings show that image has weak correlation towards tourist attraction of Solo. It means most of the tourists are not influenced by city image when they choose Solo as one of their travel destination. The differences between primary and minor image are also examined. Research implication is directed for local government to pursue continuous improvement particularly for the branding of Solo.

    Research on mass murder is limited due to differences in definitions (particularly with respect to victim count), as well as categorizations based on motive. These limitations restrict our understanding of the offending, adjudication, and outcome patterns of these offenders and can obscure potential underlying similarities to comparable types of offenders (e.g., lone actors or terrorists). To address some of these limitations, this research study, which includes an international sample of 434 cases (455 total offenders), uses descriptive and empirical analyses of solo male, solo female, and partnered mass murderers (teams of two or more) to explore offending, adjudication, and outcome patterns among these different types offenders. While the results from this research study support much previous mass murder research, the findings also emphasize the importance of large international sample sizes, objective categorizations, and the use of empirically based analyses to further advance our understanding of these offenders.

    Full Text Available A compreensão e a quantificação do impacto do uso e manejo do solo na qualidade física são fundamentais no desenvolvimento de sistemas agrícolas sustentáveis. Com o objetivo de avaliar o efeito de sistemas de manejo de solo e de rotação de culturas sobre alguns atributos físicos de solo em um experimento instalado em 1985, em Latossolo Vermelho Distrófico típico argiloso, em Passo Fundo (RS, estudou-se a variação desses atributos entre 2001 e 2005. Os tratamentos consistiram de quatro modos de manejo de solo: 1 plantio direto (PD; 2 cultivo mínimo (CM; 3 preparo convencional de solo com arado e grade de discos (PCD e 4 preparo convencional de solo com arado de aivecas e grade de discos (PCA, e três sistemas de rotação de culturas: I (trigo/soja, II (trigo/soja e ervilhaca/milho ou sorgo e III (trigo/soja, aveia branca/soja e ervilhaca/milho ou sorgo. O delineamento experimental foi em blocos completos ao acaso, com parcelas subdivididas e três repetições. A parcela foi constituída pelos sistemas de manejo de solo, e as subparcelas, pelos sistemas de rotação de culturas. Amostras de solo também foram coletadas em um fragmento de floresta subtropical adjacente ao experimento, como testemunha da condição original do solo. Os sistemas de manejo e de rotação de culturas influenciaram os atributos físicos do solo quando comparados entre si e com a condição sob floresta subtropical. Em quatro anos (2001 a 2005 ocorreram alterações significativas nos atributos físicos dos solos entre os distintos tipos de manejo. No sistema PD houve maior densidade de solo e microporosidade em comparação aos demais, principalmente na camada subsuperficial, e os sistemas de rotação de plantas não afetaram positivamente os atributos físicos de solo independentemente do tipo de manejo.Evaluation and quantification of soil use impact on its physical quality are important to achieve sustainable cropping systems.

    A phoniatrist analyzes the professional's voice at the beginning of his vocal studies or career but also later, in cases of voice disorder. Phoniatric examination of professional singers must be done according to "all inclusive" protocols of examination. Such protocols must establish the status of basic elements of phonatory system: activator, generator and resonator of voice and articulatory space. All patients requiring phoniatric examination no matter if they are candidates for professional singers, need to provide anamnestic data about their previous problems regarding voice or singing. This examination is necessary and it must include: examination of nose, cavum oris, pharynx, ears and larynx. This analysis is based on evaluation of physiological and pathophysiological manifestations of voice. Determination of musical voice range during phoniatric examination does not intend to make any classification of voice, nor to suggest to vocal teacher what he should count upon from future singers. Musical range can be determined only by a phoniatrist skilled in music or with musical training, but first of all vocal teacher. These methods are used for examination of phonatory function, or laryngeal pathology. They are not invasive and give objective and quantitative information. They include: laryngostroboscopy, spectral analysis of voice (sonography) and fundamental parameters of voice signal (computer program). Articulation is very important for solo singers, because good articulation contributes to qualitative emission of sound and expression of emotions. Tonal-threshold audiometry is performed as a hearing test. They include rhinomanometry, vital capacity measurements, maximal phonation time and phonation quotient. Phoniatric examination is a necessary proceeding which must be performed before admission to the academy of solo singing, and then during singers' education and career. The phoniatric protocol must include a minimal number of parameters, which can be

    2012-09-01

    This NREL technical report utilizes a development framework originated by NREL and known by the acronym SROPTTC to assist the U.S. Virgin Islands in identifying and understanding concrete opportunities for wind power development in the territory. The report covers each of the seven components of the SROPTTC framework: Site, Resource, Off-take, Permitting, Technology, Team, and Capital as they apply to wind power in the USVI and specifically to a site in Bovoni, St. Thomas. The report concludes that Bovoni peninsula is a strong candidate for utility-scale wind generation in the territory. It represents a reasonable compromise in terms of wind resource, distance from residences, and developable terrain. Hurricane risk and variable terrain on the peninsula and on potential equipment transport routes add technical and logistical challenges but do not appear to represent insurmountable barriers. In addition, integration of wind power into the St. Thomas power system will present operational challenges, but based on experience in other islanded power systems, there are reasonable solutions for addressing these challenges.

  19. Parallel Directionally Split Solver Based on Reformulation of Pipelined Thomas Algorithm

    1998-01-01

    In this research an efficient parallel algorithm for 3-D directionally split problems is developed. The proposed algorithm is based on a reformulated version of the pipelined Thomas algorithm that starts the backward step computations immediately after the completion of the forward step computations for the first portion of lines This algorithm has data available for other computational tasks while processors are idle from the Thomas algorithm. The proposed 3-D directionally split solver is based on the static scheduling of processors where local and non-local, data-dependent and data-independent computations are scheduled while processors are idle. A theoretical model of parallelization efficiency is used to define optimal parameters of the algorithm, to show an asymptotic parallelization penalty and to obtain an optimal cover of a global domain with subdomains. It is shown by computational experiments and by the theoretical model that the proposed algorithm reduces the parallelization penalty about two times over the basic algorithm for the range of the number of processors (subdomains) considered and the number of grid nodes per subdomain.

  20. Solo and keratin filaments regulate epithelial tubule morphology.

    Epithelial tubules, consisting of the epithelial cell sheet with a central lumen, are the basic structure of many organs. Mechanical forces play an important role in epithelial tubulogenesis; however, little is known about the mechanisms controlling the mechanical forces during epithelial tubule morphogenesis. Solo (also known as ARHGEF40) is a RhoA-targeting guanine-nucleotide exchange factor that is involved in mechanical force-induced RhoA activation and stress fiber formation. Solo binds to keratin-8/keratin-18 (K8/K18) filaments, and this interaction plays a crucial role in mechanotransduction. In this study, we examined the roles of Solo and K8/K18 filaments in epithelial tubulogenesis using MDCK cells cultured in 3D collagen gels. Knockdown of either Solo or K18 resulted in rounder tubules with increased lumen size, indicating that Solo and K8/K18 filaments play critical roles in forming the elongated morphology of epithelial tubules. Moreover, knockdown of Solo or K18 decreased the level of diphosphorylated myosin light chain (a marker of contractile force) at the luminal and outer surfaces of tubules, suggesting that Solo and K8/K18 filaments are involved in the generation of the myosin II-mediated contractile force during epithelial tubule morphogenesis. In addition, K18 filaments were normally oriented along the long axis of the tubule, but knockdown of Solo perturbed their orientation. These results suggest that Solo plays crucial roles in forming the elongated morphology of epithelial tubules and in regulating myosin II activity and K18 filament organization during epithelial tubule formation.

Simultaneous measurements of soil water content and pressure head are made along a 125 m transect within an irrigated field during the internal drainage process. Calculations of the soil hydraulic conductivity were made using the instantaneous profile method (Watson, 1966 and the unit gradient method (LIBARDI et al., 1980. The spatial variability of the soil hydraulic conductivity manifested along the transect indicates the need to develop a field method to measure K(theta within prescribed fiducial limits, taking into account quantitative evaluation of spatial and temporal variances associated with the mathematical model, instrument calibration and soil properties.São apresentados dados experimentais de condutividade hidráulica do solo, para uní Alfisol (terra roxa estruturada do Município de Piracicaba,SP - Brasil.

    2010-01-01

    In the present article, the 'pasta' phase is studied at finite temperatures within a Thomas-Fermi (TF) approach. Relativistic mean-field models, both with constant and density-dependent couplings, are used to describe this frustrated system. We compare the present results with previous ones obtained within a phase-coexistence description and conclude that the TF approximation gives rise to a richer inner ''pasta'' phase structure and the homogeneous matter appears at higher densities. Finally, the transition density calculated within TF is compared with the results for this quantity obtained with other methods.

    Eigenvectors have been calculated for the A=18, 19, 20, 21, and 26 nuclei in an sd shell basis. The decomposition of these states into their shell model components shows, in agreement with other recent work, that this distribution is not a single Gaussian. We find that the largest amplitudes are distributed approximately in a Gaussian fashion. Thus, many experimental measurements should be consistent with the Porter-Thomas predictions. We argue that the non-Gaussian form of the complete distribution can be simply related to the structure of the Hamiltonian

    We use the continuum shell model approach to explore the resonance width distribution in unstable many-body systems. The single-particle nature of a decay, the few-body character of the interaction Hamiltonian, and the collectivity that emerges in nonstationary systems due to the coupling to the continuum of reaction states are discussed. Correlations between the structures of the parent and daughter nuclear systems in the common Fock space are found to result in deviations of decay width statistics from the Porter-Thomas distribution.

    Understanding practice behaviors of solo/dual physician ownership and associated factors at the national level is important information for policymakers and clinicians in response to the Affordable Care Act (ACA) of 2010, but poorly understood in the literature. We analyzed nationally representative data (n = 4,720). The study results reveal nearly 33% of the sample reported solo/two-physician practices. Male/minority/older physicians, psychiatrists, favor small practices. Greater market competition was perceived and less charity care was given among solo/two-physician practitioners. The South region was favored by small physician practitioners. Physicians in solo or two-person practices provided fewer services to chronic patients and were dissatisfied with their overall career in medicine. Small practices were favored by international medical graduates (IMGs) and primary care physicians (PCPs). Overall our data suggest that the role of solo/dual physician practices is fading away in the delivery of medicine. Our findings shed light on varied characteristics and practice behaviors of solo/two-physician practitioners, but more research may be needed to reevaluate the potential role of small physician practitioners and find a way to foster a private physician practice model in the context of the newly passed ACA of 2010.

    Recent shell model calculations have yielded width amplitude distributions which have apparently not agreed with the Porter-Thomas distribution. This result conflicts with the present experimental evidence. A reanalysis of these calculations suggests that, although correct, they do not imply that the Porter-Thomas distribution will fail to describe the width distributions observed experimentally. The conditions for validity of the Porter-Thomas distribution are discussed

    1993-01-01

    Fluctuations associated with stretched E2 transitions from high-spin levels in nuclei around 168 Yb are investigated by a cranked shell model extended to include residual two-body interactions. In the cranked mean-field model without residual interactions, it is found that gamma-ray energies behave like random variables and the energy spectra show Poisson fluctuation. With two-body residual interactions included, the discrete transition pattern with unmixed rotational bands is still valid up to around 600 keV above yrast, in good agreement with experiments. At higher excitation energy, a gradual onset of rotational damping emerges. At 1.8 MeV above yrast, complete damping is observed with GOE-type fluctuations for both energy levels and transition strengths (Porter-Thomas fluctuations). (orig.)

    We construct noncommutative Donaldson-Thomas invariants associated with abelian orbifold singularities by analyzing the instanton contributions to a six-dimensional topological gauge theory. The noncommutative deformation of this gauge theory localizes on noncommutative instantons which can be classified in terms of three-dimensional Young diagrams with a colouring of boxes according to the orbifold group. We construct a moduli space for these gauge field configurations which allows us to compute its virtual numbers via the counting of representations of a quiver with relations. The quiver encodes the instanton dynamics of the noncommutative gauge theory, and is associated to the geometry of the singularity via the generalized McKay correspondence. The index of BPS states which compute the noncommutative Donaldson-Thomas invariants is realized via topological quantum mechanics based on the quiver data. We illustrate these constructions with several explicit examples, involving also higher rank Coulomb branch invariants and geometries with compact divisors, and connect our approach with other ones in the literature.

  19. Some notes on time dependent Thomas Fermi approximation

    Holzwarth, G.

    1979-01-01

    The successful use of effective density-dependent potentials in static Hartree-Fock calculations for nuclear ground-state properties has led to the question whether it is possible to obtain significant further simplification by approximating also the kinetic energy part of the ground state energy by a functional of the local density alone. The great advantage of such an approach is that its complexity is independent of particle number; the size of the system enters only through parameters, Z and N. The simple 'extended Thomas Fermi' functionals are based on the assumption of a spherically symmetric local Fermi surface throughout the nucleus and they represent the 'liquid drop' part of the static total energy. Given this static formalism which is solved directly for the local density without considering individual particles one might ask for a possible dynamical extension in the same sense as TDHF is a dynamical extension of the static HF approach. The aim of such a Time Dependent Thomas Fermi (TDTF) approximation would be to determine directly the time-dependent local single-particle density from given initial conditions and the single-particle current density without following each particle on its individual orbit

This short story tells about two female character have closerelationship to the same man. The man comes from upper class. The first woman from lower class has a son of his, but they do not live together. Then, the second one is his new young wife. This short story takes rural area, Dorset as the setting of place where the society has intimate relationships and setting of time is in Victorian era. It applied feminism theory that focuses on male and female positions in society. Beauvoir (1949 considered that the male in French and Western societies defines what it means to be human and what it means to be female. The female becomes subordinate to the male. It applies qualitative analysis method. The text is analyzed relating to the female characters‘ position in society. Their positions make them get discrimination which society created. Thomas Hardy‘s short story will be analyzed on discrimination to female characters. The data shows that the two female characters are oppressed on their conditions. Although they do not get physical harassment, the oppression comes from social injustice that women do not get equal benefit and opportunities. Both of them survive to obtain what they need. These characters use their ways as the survivors because of unfair condition.

Pero poco se ha hablado del papel y condiciones necesarias del comerciante como agente que hizo posible que los primeros Estados-Nación se convirtieran en las futuras potencias económicas del mundo occidental. Thomas Mun fue uno de aquellos escritores mercantilistas que destacó el papel del comerciante en el auge del sistema mercantilista. El estudio de sus ideas permite concluir que sus recomendaciones acerca de lo que debería ser un comerciante de éxito siguen vigentes hoy en día. La razón de tal afirmación estriba en que sus recomendaciones eran adecuadas en un marco en que se estaba presentando una transformación significativa del sistema de organización comercial con la presencia de la Joint-Stock Company. Independientemente de que muchas de las funciones que Thomas Mun le atribuía al comerciante hoy en día son especializadas, su dominio sigue siendo la clave del éxito de una política comercial que emprenda cualquier nación.

  3. Thomas Willis: the faculties and his two cognitive frameworks.

    2014-11-01

    Thomas Willis' 1664 study The anatomy of the brain is widely regarded as one of the first clinical studies of the brain. In Theanatomy, Thomas Willis explicitly connected the cognitive faculties and the nerves. Willis' later, 1672 work, The two discourses concerning the soul of brutes, severely undermined the materialism of Willis' first study: he affirmed dualism and cognitive immateriality; changed the anatomical locations of cognition; and reasserted a division between the rational and sensitive souls. His exact motive to return to orthodoxy is unclear, but contemporary scholarship of Willis has compounded the confusion with by relying predominantly on The soul of brutes instead of The anatomy. We trace Willis' career and examine his methodological practices, which help explain the historical practices and pressures. A closer examination of Willis' Anatomy of the brain reveals a much more materialistic account of the brain, the faculties, and nervous system. In this article, we present our own analysis of Willis' concept of rationality in the Anatomy and explain its importance for nervous physiology and understanding the analytic techniques for first defining faculty localizations. We then explain the role of the imagination and the immortal soul in the rearticulated anatomical concepts from The soulof brutes. Copyright © 2014 Elsevier Inc. All rights reserved.

  4. Philosophical Creationism: Thomas Aquinas’ Metaphysics of Creatio ex Nihilo

    Full Text Available All philosophers, beginning with the pre-Socratics, through Plato and Aristotle, and up to Thomas Aquinas, accepted as a certain that the world as a whole existed eternally. The foundation for the eternity of the world was the indestructible and eternal primal building material of the world, a material that existed in the form of primordial material elements (the Ionians, in the form of ideas (Plato, or in the form of matter, eternal motion, and the first heavens (Aristotle. The article outlines the main structure of the philosophical theory of creation ex nihilo developed by St. Thomas Aquinas and indebted to his metaphysical thought. It shows the wisdom-based and ratiocinative foundation of the rational cognition of reality—reality that comes from the personal creative act of God. It concludes that the perception that the beings called to existence by the personal act of God the Creator are intelligible is the ultimate rational justification for the fact that our human cognition, love, and spiritual creativity are rational.

  5. Obituary: Thomas C. Van Flandern (1940-2009)

    Dunham, David; Slabinski, Victor

    2011-12-01

    Dr. Thomas Charles Van Flandern, an expert in celestial mechanics and cosmology, died January 9, 2009 in Seattle, Washington, of colon cancer. He was 68. Van Flandern was an astronomer at the U.S. Naval Observatory from 1963 to 1983. He developed software to predict and analyze lunar occultations to improve lunar orbital and fundamental star catalog data. In later years he championed increasingly controversial theories. But his 1978 prediction that some asteroids have natural satellites, which was almost universally rejected, was verified when the Galileo spacecraft photographed Dactyl, a satellite of (243) Ida, during its flyby in 1993. Besides astronomy and computers, he had strong interests in biochemistry and nutrition, and he ran a business selling personal computers in the 1980s. Tom Van Flandern was born June 26, 1940 in Cleveland, Ohio, the first child of Robert F. Van Flandern and Anna Mary Haley. His father, a police officer, left the family when Tom Van Flandern was 5. His mother died when he was 16; he and his siblings then lived with their grandmother, Margery Jobe, until he went to college. Tom Van Flandern became interested in astronomy as a child. He used his first telescope, purchased with newspaper delivery earnings, to observe lunar occultations, and then learned how to predict them, sparking a life-long passion for dynamical astronomy. While attending St. Ignatius High School, Van Flandern and fellow student Thomas Petrie organized the Cleveland Moonwatch team to observe the first artificial satellites, the only team without an adult organizer. In 1958, Tom Van Flandern entered Xavier University where he led the Cincinnati Moonwatch team. He learned computer programming at a summer job with General Electric and wrote software to calculate "look angles" from orbital elements. The Cincinnati team became a top producer of observations using these predictions. Tom obtained a B.S. in mathematics from Xavier in 1962. He spent the next year at

  6. Visual Composition of Bodily Presence. A Phenomenological Approach to Paul Thomas Anderson’s The Master

    Full Text Available The description and interpretation of the visual composition of a film is crucial in understanding the effects of moving images and their specific role in the contemporary context of intermediality. The phenomenological approach, based on the precise depiction of the lived perceptual experience and its integration in the process of interpretation, offers a powerful tool for critical analysis. Although this theoretical framework opens up many different approaches, in this paper I will focus on Merleau-Pontyʼs phenomenological account of perception and on the viewer experience described by Vivian Sobchack with the self-contradictory term “a filmʼs body.” After studying this concept and its role in film analysis, as used by Sobchack, based on the term double-sided and fissured experience the paper offers an alternative approach which, compared to the earlier ones, seems to be more fruitful in understanding the act of vision and the embodied viewer experience constructed by a moving picture. The last part of the paper demonstrates, through the example of Paul Thomas Andersonʼs The Master (2012, how crucial the embodied viewer experience can be in the understanding of moving images. The analysis of the visual system of this film will show how the main problem of the whole story is re-created, re-presented in the visually triggered bodily experience of the viewer.

    2016-03-01

    To investigate the feasibility and safety of solo surgery with single-port laparoscopic appendectomy, which is termed herein solo-SPLA (solo-single-port laparoscopic appendectomy). This study prospectively collected and retrospectively analyzed data from patients who had undergone either non-solo-SPLA (n = 150) or solo-SPLA (n = 150). Several devices were utilized for complete, skin-to-skin solo-SPSA, including a Lone Star Retractor System and an adjustable mechanical camera holder. Operating times were not significantly different between solo- and non-solo-SPLA (45.0 ± 21.0 minutes vs. 46.7 ± 26.1 minutes, P = 0.646). Most postoperative variables were also comparable between groups, including the necessity for intravenous analgesics (0.7 ± 1.2 ampules [solo-SPLA] vs. 0.9 ± 1.5 ampules [non-solo-SPLA], P = 0.092), time interval to gas passing (1.3 ± 1.0 days vs. 1.4 ± 1.0 days, P = 0.182), and the incidence of postoperative complications (4.0% vs. 8.7%, P = 0.153). Moreover, solo-SPLA effectively lowered the operating cost by reducing surgical personnel expenses. Solo-SPLA economized staff numbers and thus lowered hospital costs without lengthening of operating time. Therefore, solo-SPLA could be considered a safe and feasible alternative to non-solo-SPLA.

    luxR genes encode transcriptional regulators that control acyl homoserine lactone-based quorum sensing (AHL QS) in Gram negative bacteria. On the bacterial chromosome, luxR genes are usually found next or near to a luxI gene encoding the AHL signal synthase. Recently, a number of luxR genes were described that have no luxI genes in their vicinity on the chromosome. These so-called solo luxR genes may either respond to internal AHL signals produced by a non-adjacent luxI in the chromosome, or can respond to exogenous signals. Here we present a survey of solo luxR genes found in complete and draft bacterial genomes in the NCBI databases using HMMs. We found that 2698 of the 3550 luxR genes found are solos, which is an unexpectedly high number even if some of the hits may be false positives. We also found that solo LuxR sequences form distinct clusters that are different from the clusters of LuxR sequences that are part of the known luxR-luxI topological arrangements. We also found a number of cases that we termed twin luxR topologies, in which two adjacent luxR genes were in tandem or divergent orientation. Many of the luxR solo clusters were devoid of the sequence motifs characteristic of AHL binding LuxR proteins so there is room to speculate that the solos may be involved in sensing hitherto unknown signals. It was noted that only some of the LuxR clades are rich in conserved cysteine residues. Molecular modeling suggests that some of the cysteines may be involved in disulfide formation, which makes us speculate that some LuxR proteins, including some of the solos may be involved in redox regulation.

  13. Paired Synchronous Rhythmic Finger Tapping without an External Timing Cue Shows Greater Speed Increases Relative to Those for Solo Tapping.

    2017-03-09

    In solo synchronization-continuation (SC) tasks, intertap intervals (ITI) are known to drift from the initial tempo. It has been demonstrated that people in paired and group contexts modulate their action timing unconsciously in various situations such as choice reaction tasks, rhythmic body sway, and hand clapping in concerts, which suggests the possibility that ITI drift is also affected by paired context. We conducted solo and paired SC tapping experiments with three tempos (75, 120, and 200 bpm) and examined whether tempo-keeping performance changed according to tempo and/or the number of players. Results indicated that those tapping in the paired conditions were faster, relative to those observed in the solo conditions, for all tempos. For the faster participants, the degree of ITI drift in the solo conditions was strongly correlated with that in the paired conditions. Regression analyses suggested that both faster and slower participants adapted their tap timing to that of their partners. A possible explanation for these results is that the participants reset the phase of their internal clocks according to the faster beat between their own tap and the partners' tap. Our results indicated that paired context could bias the direction of ITI drift toward decreasing.

    2018-03-01

    The purpose of this descriptive report is to provide the first representative information on the sociodemographic profile and the prevalence of mental and physical health conditions of two "at-risk" groups of Latino caregivers: solo grandparent caregivers and single parents. The 2012 Behavior Risk Factor Surveillance System was used to compare five dimensions of health on a sample of Latino solo grandparents and Latino single parents, raising their grandchildren/children alone. Bivariate and logistic regression comparative analyses were conducted on study measures. Latino solo grandparents have a high prevalence of chronic health conditions, including arthritis (51%), depression (40%), diabetes (34%), and asthma (34%). Latino single parents have lower but troubling health risks, including depression (22%), diabetes (14%), and asthma (14%). Differences between the two groups were largely due to the grandparents older age. Latino solo grandparents have a high prevalence of several chronic medical conditions. The prevalence of disorders is much lower for Latino single parents, although they too have disturbing health risks. Latino solo grandparents perform their parenting role under intense physical and emotional strain. Health professionals can be instrumental in facilitating interventions that affect the well-being of this expanding family group.

  11. Green leviathan? Thomas hobbes, joel bakan and Arnold schwarzenegger.

    Science.gov (United States)

    Evans, Robert G

    2007-02-01

    Thomas Hobbes postulates that men are driven by "a perpetual and restless desire of power after power, that ceaseth only in death." The miserable consequences of this drive for power and the competing "desire of ease and sensual delight" and "fear of death and wounds" lead them to establish and obey. Substituting "profit" for "power" yields a description of the modern corporation, but without the desires or fears of natural persons. Such "unnatural persons" lack the Hobbesian ground of obligation, yet have appropriated the privileges and protections of natural persons. They challenge or undermine the sovereign wherever it limits their profits. Governor Schwarzenegger's re-election in California, however, on a strong anti-CO(2) program, suggests a willingness by threatened natural persons to re-empower Leviathan.

    The SPIRES database was created in the late 1960s to catalogue the high energy physics preprints received by the SLAC Library. In the early 1990s it became the first database on the web and the first website outside of Europe. Although indispensible to the HEP community, its aging software infrastructure is becoming a serious liability. In a joint project involving CERN, DESY, Fermilab and SLAC, a new database, INSPIRE, is being created to replace SPIRES using CERN's modern, open-source Invenio database software. INSPIRE will maintain the content and functionality of SPIRES plus many new features. I describe this evolution from the birth of SPIRES to the current day, noting that the career of Tony Thomas spans this timeline.

  16. Whistles, bells, and cogs in machines: Thomas Huxley and epiphenomenalism.

    Science.gov (United States)

    Greenwood, John

    2010-01-01

    In this paper I try to shed some historical light upon the doctrine of epiphenomenalism, by focusing on the version of epiphenomenalism championed by Thomas Huxley, which is often treated as a classic statement of the doctrine. I argue that it is doubtful if Huxley held any form of metaphysical epiphenomenalism, and that he held a more limited form of empirical epiphenomenalism with respect to consciousness but not with respect to mentality per se. Contrary to what is conventionally supposed, Huxley's empirical epiphenomenalism with respect to consciousness was not simply based upon the demonstration of the neurophysiological basis of conscious mentality, or derived from the extension of mechanistic and reflexive principles of explanation to encompass all forms of animal and human behavior, but was based upon the demonstration of purposive and coordinated animal and human behavior in the absence of consciousness. Given Huxley's own treatment of mentality, his characterization of animals and humans as "conscious automata" was not well chosen.

In external potentials, VWK passes through the average of the quantal values of the accumulated level density and total energy as a function of the Fermi energy. However, there is a problem of overbinding when the energy per particle is displayed as a function of the particle number. The situation is analyzed comparing spherical and deformed harmonic oscillator potentials. In the self-consistent case, we show for Skyrme forces that VWK binding energies are very close to those obtained from extended Thomas-Fermi functionals of h 4 order, pointing to the rapid convergence of the VWK theory. This satisfying result, however, does not cure the overbinding problem, i.e., the semiclassical energies show more binding than they should. This feature is more pronounced in the case of Skyrme forces than with the relativistic mean field approach. However, even in the latter case the shell correction energy for e.g., 208 Pb turns out to be only ∼-6 MeV what is about a factor two or three off the generally accepted value. As an ad hoc remedy, increasing the kinetic energy by 2.5%, leads to shell correction energies well acceptable throughout the periodic table. The general importance of the present studies for other finite Fermi systems, self-bound or in external potentials, is pointed out

    Creating curriculums that develop physical therapy (PT) students into evidenced-based, critically reflective, entry-level practitioners is one of the primary goals for PT programs. Academic faculty partnering with neurologic residency programs to design learning environments that capitalize upon the strengths of both can create insightful educational experiences for students during their didactic training. These partnerships support the development of critical thinking skills and provide mentorship for residents transitioning from their role as a clinician to that of an educator. Using the SOLO (structure of observed learning outcomes) taxonomy as a framework for developing learning experiences, Seton Hall University neurologic academic faculty and program directors from the Kessler Institute for Rehabilitation Residency in Neurologic Physical Therapy have built a partnership that seeks to develop critical reflection skills in both the neurologic resident and entry-level PT students. While integration of residents into entry-level PT curriculum may not be novel, we believe that utilizing the SOLO model within this partnership is unique. This paper describes the partnership and learning experiences rooted in the SOLO taxonomy theoretical framework and discusses perceived benefits of this learning experience across professional health science programs.

    The objective of this study was to present the initial operative experience of solo surgeon single-port laparoscopic surgery (SPLS) in the laparoscopic treatment of benign gynecologic diseases and to investigate its feasibility and surgical outcomes. Using a novel homemade laparoscope-anchored instrument system that consisted of a laparoscopic instrument attached to a laparoscope and a glove-wound retractor umbilical port, we performed solo surgeon SPLS in 13 patients between March 2011 and June 2012. Intraoperative complications and postoperative surgical outcomes were determined. The primary operative procedures performed were unilateral salpingo-oophorectomy (n = 5), unilateral salpingectomy (n = 2), adhesiolysis (n = 1), and laparoscopically assisted vaginal hysterectomy (n = 5). Additional surgical procedures included additional adhesiolysis (n = 4) and ovarian drilling (n = 1).The primary indications for surgery were benign ovarian tumors (n = 5), ectopic pregnancy (n = 2), pelvic adhesion (infertility) (n = 1), and benign uterine tumors (n = 5). Solo surgeon SPLS was successfully accomplished in all procedures without a laparoscopic assistant. There were no intraoperative or postoperative complications. Our laparoscope-anchored instrument system obviates the need for an additional laparoscopic assistant and enables SPLS to be performed by a solo surgeon. The findings show that with our system, solo surgeon SPLS is a feasible and safe alternative technique for the treatment of benign gynecologic diseases in properly selected patients.

    In 1978 a sample of 158 solo mothers was interviewed by third year psychology students under the supervision of the author to obtain data both on their child rearing practices (for comparison with data obtained the year before from a sample of dual parents) and on their social circumstances. These data indicate that in the case of women who had previously been married, most aspects of their life, with the exception of finance, are now improved. Freedom from conflict and greater independence are cited as the advantages of being a solo parent; loneliness and responsibility are the major disadvantages. Parents and friends are the chief sources of support.

  4. The light bulb, cystoscopy, and Thomas Alva Edison.

    Moran, Michael E

    2010-09-01

    Thomas Alva Edison was an icon of American achievement who literally invented the 20th century. Although best known as the inventor of the electric light bulb, the phonograph, and motion pictures, he also left a lasting legacy via peripheral developmental applications, such as endoscopes. A review of published urologic writings about incandescent cystoscopes was cross-referenced to writings about or from Edison. Important events that allowed transference of technology from the Edison laboratory to clinical practice were emphasized. Edison was born in 1847 while Lincoln was serving in Congress; he died in 1931 when Hoover struggled with the Great Depression. Edison's life spanned the formative period of America that Henry Adams called the "coming of age." Edison received a Sprengel vacuum device in late 1879, and as usual, he was able to tweak the machine to better performance. For 5 days in October, 16 to 21, he improved the vacuum from 1/100,000 to 1/1,000,000 atm, and his first incandescent bulb burned softly. On December 21, 1879, he leaked the story to N.Y. Herald journalist Marshall Fox, and the world was notified of the light bulb. Special Christmas light visits started in Menlo Park just 4 days later. Edison patented the screw cap for easy changes, and the first bulbs sold for 40 cents (cost $1.40). 100,000 bulbs sold in 1882, 4 million by 1892, and 45 million in 1903. Immediately, competitors and specialty manufacturers entered the market. Dr. Henry Koch and Charles Preston in Rochester, N.Y., developed a smaller, low amperage bulb that could be fitted to medical devices. No discussion of electricity and modern applications would be complete without some discussion of Thomas Alva Edison and his sentinel contributions. The first church, post office, and ship were illuminated in 1892. The first hotel, theater, and electric sign were in 1893. The rapidity of dispersal and secondary applications of Edison's inventions is typified by the rise of cystoscopes

    2012-08-01

    The fact that a significant percentage of dentists employ dental hygienists raises an important question: Are dental practices that utilize a dental hygienist structurally and operationally different from practices that do not? This article explores differences among dental practices that operate with and without dental hygienists. Using data from the American Dental Association's 2003 Survey of Dental Practice, a random sample survey of U.S. dentists, descriptive statistics were used to compare selected characteristics of solo general practitioners with and without dental hygienists. Multivariate regression analysis was used to estimate the effect of dental hygienists on the gross billings and net incomes of solo general practitioners. Differences in practice characteristics--such as hours spent in the practice and hours spent treating patients, wait time for a recall visit, number of operatories, square feet of office space, net income, and gross billings--were found between solo general practitioners who had dental hygienists and those who did not. Solo general practitioners with dental hygienists had higher gross billings. Higher gross billings would be expected, as would higher expenses. However, net incomes of those with dental hygienists were also higher. In contrast, the mean waiting time for a recall visit was higher among dentists who employed dental hygienists. Depending on personal preferences, availability of qualified personnel, etc., dentists who do not employ dental hygienists but have been contemplating that path may want to further research the benefits and opportunities that may be realized.

  8. "Telling a Story." On the Dramaturgy of Monophonic Jazz Solos

    2016-07-01

    Full Text Available The metaphor of storytelling is widespread among jazz performers and jazz researchers. However, little is known about the precise meaning of this metaphor on an analytical level. The present paper attempts to shed light on the connected semantic field of the metaphor and relate it to its musical basis by investigating time courses of selected musical elements and features in monophonic jazz improvisations. Three explorative studies are carried out using transcriptions of 299 monophonic jazz solos from the Weimar Jazz Database. The first study inspects overall trends using fits of quadratic polynomials onto loudness and pitch curves. The second study does the same using selected features related to intensity, tension and variability over the course of phrases in the solos. The third study examines the distribution of the relative positions of various improvisational ideas in a subset of 116 solos. Results show that certain trends can be found, but not to a large extent. Significant trends most often display arch-shaped curves as expected from classical dramatic models. This is also in accordance with the fact that expressive improvisational ideas are more often found in the last part of a solo, while more relaxed ideas occur earlier. All in all, jazz improvisations show a wide range of variation and no single overarching dramatic model could be identified.

  13. Musicality as an Aesthetic Process of Filtering in Thomas W. Shapcott's Poetry

    Directory of Open Access Journals (Sweden)

    Muslim Abbas Eidan Al-Ta'an

    2017-11-01

    Full Text Available How does music transcend individual experience? Is music the filter to purify everything? How does everything in the poet become music? Such questions are raised, now and then, by the conscious reader of poetry in general and that of the Australian poet Thomas W. Shapcott in particular. My present research-paper attempts to present an answer for these questions via probing the individuality of Shapcott's poetic experience and how does the poet's personal and experimental musicality as an artistic motif and aesthetic perspective play a key role in purifying language of its lies and its daily impurities. In the first place, my account is apt to find an aesthetic meaning for the action of transcending the individual experience in selected poems written by Shapcott. The philosophical and ritual thought of musicality is interplayed with the aesthetic power of poetry. Both aesthetic energies stem from the individual experience of the poet to transcend the borders of individuality and being absorbed and saturated in the wide pot of human universality. In other words, the poem after being filtered and purified musically and aesthetically is no longer an individual experience owned by its producer only, rather it becomes a human experience for its conscious readers. Music as a motif and meaning, regardless of its technical significance, is controversial in Shapcott's poetic diction. Music, here, is not a mere artistic genre; rather it is a ritualistic and philosophical thought. The paper is to investigate how Shapcott's musicality is constructed on aesthetics of balance and conformity in poetry and life.

This happens in many communities in cities of Indonesia, including Solo. With a population of 500 thousand at night and 1.5 million during the day, it is a potential market for global products. Therefore, it is obvious if the Solo people's tastes are no different than other communities, because of the consumer behaviour and global economy that are intertwined. The value of the meaning of products have also shifted, such as with cars. Cars that usually function as a vehicle no different than a wagon, have changed into a symbol of social class for the modern society, even for the people of Solo. The functions and facilities of the Various brands and types of cars, and elements that are related to automotive technology, are not too different. What makes the difference between these cars lays on the design of the form and image. This form design is able to create an image for certain social class for its user and its product brand. The most interesting phenomenon from automotive products in Indonesia is what happened with Toyota Kijang. Since its launch on 1977, Toyota Kijang, which is on its fifth generation this year, has succeeded in becoming the number one choice for cars for Indonesians.

  15. Physicians’ Perceptions of Autonomy across Practice Types: Is Autonomy in Solo Practice a Myth?

    2013-01-01

    Physicians in the United States are now less likely to practice in smaller, more traditional, solo practices, and more likely to practice in larger group practices. Though older theory predicts conflict between bureaucracy and professional autonomy, studies have shown that professions in general, and physicians in particular, have adapted to organizational constraints. However, much work remains in clarifying the nature of this relationship and how exactly physicians have adapted to various organizational settings. To this end, the present study examines physicians’ autonomy experiences in different decision types between organization sizes. Specifically, I ask: In what kinds of decisions do doctors perceive autonomous control? How does this vary by organizational size? Using stacked “spell” data constructed from the Community Tracking Study (CTS) Physician Survey (1996–2005) (n=16,519) I examine how physicians’ perceptions of autonomy vary between solo/two physician practices, small group practices with three to ten physicians, and large practices with ten or more physicians, in two kinds of decisions: logistic-based and knowledge-based decisions. Capitalizing on the longitudinal nature of the data I estimate how changes in practice size are associated with perceptions of autonomy, accounting for previous reports of autonomy. I also test whether managed care involvement, practice ownership, and salaried employment help explain part of this relationship. I find that while physicians practicing in larger group practices reported lower levels of autonomy in logistic-based decisions, physicians in solo/two physician practices reported lower levels of autonomy in knowledge-based decisions. Managed care involvement and ownership explain some, but not all, of the associations. These findings suggest that professional adaptation to various organizational settings can lead to varying levels of perceived autonomy across different kinds of decisions. PMID:24444835

  17. Thomas Hardy, Provincial Geology and the Material Imagination

    Directory of Open Access Journals (Sweden)

    Adelene Buckland

    2008-04-01

    Full Text Available This essay explores the nineteenth-century traffic and exchange of fossils and natural-historical objects between province and metropolis as represented by two very different geological writers of the period, the fossil collector Gideon Mantell and the novelist Thomas Hardy. The men are connected through Mantell's 'The Wonders of Geology', the sixth edition of which (1848 Hardy read and utilised for his descriptions of the geological past in his third novel, 'A Pair of Blue Eyes' (1873. These two texts demonstrate a powerful investment in determining the meaning of the geological object according to the social and geographical spaces in which it is discovered, displayed, and discussed, so that the scientific object becomes the site around which complex cultural politics coalesce and sit in tension. In its consideration of the relationship between place and meaning in science, and in its focus on scientific material culture, this essay attempts to disrupt the current spotlight on the interrelationships between scientific law and narrative pattern in Victorian literary studies. Instead, it hopes to contribute to a discussion of the ways in which the novel's attention to scientific objects rather than narratives made it an important site of epistemological enquiry into the basis of scientific knowledge and the inseparability of that knowledge from the discourses and spaces which produced it.

  18. THEOLOGY AS CREATIVE LANGUAGE. THE CASE OF THOMAS BROOKS

    Directory of Open Access Journals (Sweden)

    Ciprian SIMUȚ

    2015-12-01

    Full Text Available The problem of theological language has been a hindrance in coming closer to God, ever since complex patterns of thought have combined with the theological inquiry. The conclusion that helped Protestantism gain ground was bringing the theological message of the Bible to the understanding of every-day believer. An effort was made to explain how God works in history, and how to become more like Christ in one’s every-day life. However, mere copying was not the foundation of Christianity. Inner conviction born out of understanding the explanation from the Biblical message was crucial. Thomas Brooks was one of the protestant theologians who aimed to explain how the Devil and evil work against the believer, in order to create chaos, disorder, sorrow, hatred, deception, and ignorance. He did this by transforming the theological message into creative language, using every-day images in order to create a relation between theology and praxis. This paper will analyze some of the aspects found in Brooks’ theological presentation, in order to show how theology could be used for the benefit of the individual believer, as well as for the benefit of society.

  19. "The Leviathan" as automaton: method and politics in Thomas Hobbes

    Directory of Open Access Journals (Sweden)

    Diego Fernández Peychaux

    2014-02-01

    Full Text Available This article points out the tension between the normative purpose of Thomas Hobbes’s political texts, and the identification of the resolutive-compositive method of science as it is applied in those texts. In order to solve this difficulty one should appeal to Hobbes’s epistemological texts to read the example of the clock from a new perspective. Thus, if the Hobbesian method responds to the need for normative innovation, it not only denies an apologetic intentionality for a completely ignored historical reality, but also makes it possible to describe the relationship between the individual and the State in a manner different from traditional understandings. According to these conclusions, man ceases to be simply a mechanical part but rather becomes a cause, and therefore, a measure of the effectiveness and functionality of a State. Man’s savage individualism while in the state of nature is not the model, but the cause that justifies a Leviathan capable of turning the homo homini lupus into homo homini deus.

  20. A modified Thomas-Fermi treatment of nuclei

    Swiatecki, W.J.

    1992-01-01

    An improved nuclear Thomas-Fermi theory is studied in which, rather than adding density-gradient corrections to the standard expression for the kinetic energy density (proportional to ρ 5/3 , where ρ is the density) one simply modifies this ρ 5/3 function to reflect the fact that the kinetic energy density becomes negative for small values of ρ when, in a typical nuclear problem, one is dealing with the outer fringes of the surface region. The net result of this study is simply stated: In order to find the density associated with a given nuclear potential, one exponentiates this potential instead of raising its depth with respect to the chemical potential to the three-halves power, as in the standard treatment. An improved description of the nuclear surface profile is obtained, including the quantal halo in the classically forbidden region. But since density derivatives are not involved, there is no need to solve a partial differential equation in order to find the density. (orig.)

    1992-01-01

    I want to tell you about an improved Thomas-Fermi method for calculating shell-averaged nuclear properties, such as density distributions, binding energies, etc. A shell-averaged statistical theory is useful as the macroscopic component of microscopic-macroscopic theories of nuclei, such as the Strutinsky method, as well as in theories of nuclear matter in the bulk, relevant in astrophysical applications. In nuclear physics, as well as in atomic and molecular problems, the following question often has to be answered: you are given a potential well, say a deformed Woods-Saxon potential, into which you put N quantized fermions into the lowest N eigenstates, up to a ''Fermi energy'' To. You square the wave functions of the particles and add them up to get the total density ρ( r → ) = Σ i N |ψ i | 2 . Is there some simple way of estimating ρ( r → ) without going through the misery of numerically solving N partial differential Schroedinger equations for the N particles?

  2. Nietzche's echo--a dialogue with Thomas Altizer.

    2010-03-01

    Prophets provoke psychological unrest, especially when exposing accepted beliefs as profound deceptions. The biblical prophets exemplify such confrontation as do certain atheists ardently opposed to the images of God created by those seers. The German philosopher Friedrich Nietzsche dramatically illustrates this type of counterforce to the Judeo-Christian tradition. His prophet Zarathustra is intended to be a model for the modern mind, one free of superstitions inflicted by antiquated religious dogma. Nietzsche's credo "God is dead" served as a declaration for the nineteenth century. In the twentieth century, it became a theological diagnosis. As a "movement," or "tenor," the death of God or radical theology was spearheaded by Thomas Altizer, a well-published young professor center-staged during the turbulent 1960s. His work foreshadows a new strain of atheism currently represented by biologist Richard Dawkins (2006, The God delusion.

O objetivo deste trabalho foi avaliar as condições hidráulicas e as relações de desagregação do solo e de resistência ao escoamento com a presença de resíduos vegetais na erosão em entressulcos. O experimento foi realizado no laboratório, com um Argissolo Vermelho distrófico típico, em parcelas com 0,10 m m-1 de declive sob chuva simulada. O solo foi coberto por resíduos vegetais de palha de soja, nas doses de 0, 0,05, 0,1, 0,2, 0,4 e 0,8 kg m-2. O aumento na cobertura do solo (CS com resíduos vegetais elevou a altura da lâmina de escoamento e a rugosidade hidráulica e reduziu a velocidade média do escoamento, provocada pelo aumento das forças viscosas promovida pela interposição física dos resíduos ao escoamento. O resultado é a redução na taxa de desagregação do solo (Di. A Di foi de 5,35x10-4 kg m-2 s-1 para solo descoberto e 1,50x10-5 kg m-2 s-1 em solo com 100% de cobertura na maior dose de palha.

    Full Text Available A calagem do solo altera o pH e, conseqüentemente, influencia no processo de redução dos solos submetidos ao alagamento para o cultivo do arroz irrigado, alterando a disponibilidade de nutrientes na solução do solo. Entretanto, a recomendação de calcário para o arroz irrigado é variável, implicando em diferentes quantidades a aplicar, dependendo da situação. Assim, o objetivo deste trabalho foi avaliar a liberação de nutrientes para a solução do solo após o alagamento, em três solos de várzea com diferentes valores de pH, resultantes da aplicação de diferentes quantidades de calcário. Amostras de solos de várzea foram coletadas da camada de 0 a 20 cm em áreas de produção de arroz nos municípios de Cachoeirinha/RS (Gleissolo, Faxinal do Soturno (Planossolo 1 e Santa Maria (Planossolo 2, as quais foram misturadas com calcário para comporem os seguintes tratamentos: zero; ½ SMP e 1 SMP para pH 5,5 e 1 SMP para pH 6,0. Após 90 dias de incubação, as amostras foram acondicionadas em vasos plásticos com um dispositivo para coleta da solução do solo e alagadas. Aos 2, 8, 15, 22, 28, 42 e 56 dias de alagamento foram retiradas amostras da solução do solo e determinados os teores de Fe, Ca, Mg, K e P. Com os maiores valores de pH, diminuíram os teores de ferro na solução, aumentaram os de cálcio e magnésio e não afetaram os teores de fósforo e potássio. As concentrações dos nutrientes e as mudanças provocadas pela calagem foram diferentes nos três solos.Liming changes soil pH, reduction process and nutrient availability in flooded soils used for rice production.

Nos demais cinco tratamentos, o solo foi preparado por meio de uma operação conjugada (escarificador equipado com rolo destorroador. Na testemunha e em um dos tratamentos sob preparo conjugado, não foram realizadas adaptações na semeadora-adubadora. Nos demais tratamentos, foram adaptados discos de corte ondulados, ou secções de rolos destorroadores, na frente das linhas da semeadora. A percentagem de cobertura do solo, dois dias após a semeadura, foi significativamente menor (Tukey ao nível de 5% na testemunha, enquanto nos demais tratamentos, caracterizados como conservacionistas, não se perceberam diferenças. O diâmetro médio geométrico (DMG dos agregados do solo não apresentou diferenças significativas entre os tratamentos, porém os agregados coletados nas linhas apresentaram DMG significativamente menores do que aqueles encontrados nas entrelinhas. A velocidade de absorção de água pelas sementes, o comprimento médio ponderado das radículas, o índice de velocidade de emergência e o estande inicial de plantas de milho não variaram significativamente em função dos tratamentos.

  5. The Balance of Faith and Reason: The Role of Confirmation in the Thought of St. Thomas Aquinas

    Directory of Open Access Journals (Sweden)

    Benjamin M. Block

    2015-09-01

    Full Text Available The evidentialist objection against Christianity, which states that the Christian faith does not have sufficient evidence to justify belief, can be troubling for Christians, for they do not wish to say that their beliefs are founded upon mere human evidence, and yet, they also wish to affirm that “those who place their faith in this truth, for which human reason offers no experience, do not believe lightly, as those following unlearned fables” (SCG I.6. St. Thomas Aquinas offers a unique and compelling solution to the evidentialist objection—a solution that confirms the Christian belief that faith is a gift from God, but which also respects the proper place of human reason within the believing life of men. St. Thomas teaches that God provides both internal and external confirmation of what He reveals, although only the internal confirmation of the work of the Holy Spirit is necessary to justify Christian belief. Aquinas’s teaching concerning the role of divine confirmation of revealed truths provides at least one important key to understanding the delicate balance between faith and reason within the Christian life.

  6. Raviart–Thomas-type sources adapted to applied EEG and MEG: implementation and results

    International Nuclear Information System (INIS)

    Pursiainen, S

    2012-01-01

    This paper studies numerically electroencephalography and magnetoencephalography (EEG and MEG), two non-invasive imaging modalities in which external measurements of the electric potential and the magnetic field are, respectively, utilized to reconstruct the primary current density (neuronal activity) of the human brain. The focus is on adapting a Raviart–Thomas-type source model to meet the needs of EEG and MEG applications. The goal is to construct a model that provides an accurate approximation of dipole source currents and can be flexibly applied to different reconstruction strategies as well as to realistic computation geometries. The finite element method is applied in the simulation of the data. Least-squares fit interpolation is used to establish Cartesian source directions, which guarantee that the recovered current field is minimally dependent on the underlying finite element mesh. Implementation is explained in detail and made accessible, e.g., by using quadrature-free formulae and the Gaussian one-point rule in numerical integration. Numerical results are presented concerning, for example, the iterative alternating sequential inverse algorithm as well as resolution, smoothness and local refinement of the finite element mesh. Both spherical and pseudo-realistic head models, as well as real MEG data, are utilized in the numerical experiments. (paper)

  7. Which Way Is Up? Thomas S. Kuhn's Analogy to Conceptual Development in Childhood

    Science.gov (United States)

    Levine, Alexander T.

    In the Preface to his Structure Of Scientific Revolutions, Thomas S. Kuhn let it be known that his view of scientific development was indebted to the work of pioneering developmental psychologist Jean Piaget. Piaget's model of conceptual development in childhood, on which the child passes through several discontinuous stages, served as the template for Kuhn's reading of the history of a scientific discipline, on which mutually incommensurable periods of normal science are separated by scientific revolutions. The analogy to conceptual change in childhood pervades Kuhn's corpus, serving as the central motif in his well-known essays, A Function for Thought Experiments and Second Thoughts on Paradigms. But it is deeply problematic. For as a careful student of Piaget might note, Piaget, and the developmental psychologists he inspired, relied on the same analogy, but with the order of epistemic dependencies reversed. One begins to worry that Kuhn's use of the analogy, and its subsequent re-use by developmental psychologists, sneaks a vicious circularity into our understanding of important processes. This circularity is grounds for some concern on the part of science educators accustomed to employing such Kuhnian notions as incommensurability and paradigm.

    The original goal of this proposal was to study frozen spin polarized targets (HD target and other technologies) and produce a conceptual design report for the implementation of such a target in the HALL B detector of the Thomas Jefferson National Accelerator Facility (JLab). During the first two years of the proposal, we came to the conclusion that the best suited target for JLab was a frozen spin target and helped with the design of such a target. We have not only achieved our original goal but have exceeded it by being involved in the actual building and testing of parts the target. The main reason for this success has been the hiring of a senior research associate, Dr. Oleksandr Dzyubak, who had more than 10 years of experience in the field of frozen spin polarized targets. The current grant has allowed the USC nuclear physics group to strengthen its role in the JLab collaboration and make important contribution to both the detector development and the scientific program

    Full Text Available When I assumed the post as Director of the School of Distance Learning and Virtual Education in March 2000, my first task was to define a strategy to follow. In a context where trends indicated a dramatic increase in the application of new information and communication technologies used to support distance learning, there was a need for new institutional policies to provide a framework to support our activity. In short, I had to decide how to organize an academic unit to support distance learning. This task called for an analysis of all educational technologies available at the time, in order to develop the courses which were to be included in our educational offer. Costs were clearly an important consideration.By recalling this three-year-old experience, I am now in a position to assert that, as stated by Hilary Perraton in the Introduction, Thomas Hülsmann’s book is an effective tool for decision makers in the field of open and distance learning.

    Thomas-Nicolas Larcheret, teacher in singing, declamation, guitar or lyre and violin, author of music and books, but also inventor of the universal elixir by his name, is a good example of quack of the 19th century. His book Larcheregium ou Dictionnaires spéciaux de mon élixir, ainsi que toute ma doctrine et de mes adhérens (Larcheregium or special Dictionaries of my elixir, as well as all my doctrine and my adherents), published in 1819, deserves a deep study to show the most frequently used arguments by the ones who emphasize the value of their secret remedy. The opportunities are there to present themselves as victims of medical authorities, experts and authorities as a whole, that do not recognize the value of their product. The only acceptable judge for them is the experience reported by the patients who are able to demonstrate the efficacy of the product since they do buy it (probably at a very high price). From this viewpoint, the book of Larcheret is a good example of turning the authorities down and of diatribe against physicians and pharmacists. It is also the demonstration that, even with the Empire's new regulations against secret remedies and quacks, they will still persist for a large part of the 19th century in France.

Launched March 8, 2001, STS-102's primary cargo was the Leonardo, the Italian Space Agency-built Multipurpose Logistics Module (MPLM). The Leonardo MPLM is the first of three such pressurized modules that will serve as the ISS's moving vans, carrying laboratory racks filled with equipment, experiments, and supplies to and from the Station aboard the Space Shuttle. The cylindrical module is approximately 21-feet long and 15- feet in diameter, weighing almost 4.5 tons. It can carry up to 10 tons of cargo in 16 standard Space Station equipment racks. Of the 16 racks the module can carry, 5 can be furnished with power, data, and fluid to support refrigerators or freezers. In order to function as an attached station module as well as a cargo transport, the logistics module also includes components that provide life support, fire detection and suppression, electrical distribution, and computer functions. NASA's 103rd overall mission and the 8th Space Station Assembly Flight, STS-102 mission also served as a crew rotation flight.

    little sister: An Afro-Temporal Solo-Play is at once a memory-scape and a mytho-biography set to poetry, movement, and mixed media. A performance poem spanning from the Antebellum South to present-moment Chicago, it tells the story of a nomadic spirit named little-she who shape-shifts through the memories and imaginings of her sister, the narrator. Through the characters little-she and the narrator, the solo-performance explores embodied ways to rupture and relieve the impact of macro forms of violence in the micro realm of the everyday. To this end, little sister witnesses and disrupts the legacy of violence in the lives of queer Black women through a trans-temporal navigation of everyday encounters within familial, small groups and intimate partner spaces.

  15. Interplay between Solo and keratin filaments is crucial for mechanical force–induced stress fiber reinforcement

    2016-01-01

    Mechanical force–induced cytoskeletal reorganization is essential for cell and tissue remodeling and homeostasis; however, the underlying cellular mechanisms remain elusive. Solo (ARHGEF40) is a RhoA-targeting guanine nucleotide exchange factor (GEF) involved in cyclical stretch–induced human endothelial cell reorientation and convergent extension cell movement in zebrafish gastrula. In this study, we show that Solo binds to keratin-8/keratin-18 (K8/K18) intermediate filaments through multiple sites. Solo overexpression promotes the formation of thick actin stress fibers and keratin bundles, whereas knockdown of Solo, expression of a GEF-inactive mutant of Solo, or inhibition of ROCK suppresses stress fiber formation and leads to disorganized keratin networks, indicating that the Solo-RhoA-ROCK pathway serves to precisely organize keratin networks, as well as to promote stress fibers. Of importance, knockdown of Solo or K18 or overexpression of GEF-inactive or deletion mutants of Solo suppresses tensile force–induced stress fiber reinforcement. Furthermore, knockdown of Solo or K18 suppresses tensile force-induced RhoA activation. These results strongly suggest that the interplay between Solo and K8/K18 filaments plays a crucial role in tensile force–induced RhoA activation and consequent actin cytoskeletal reinforcement.

Sob o cultivo do feijoeiro, foram avaliados os efeitos dos drenos torpedo e de "camas" na drenagem e de cobertura morta (palha de arroz na retenção de água do solo. Os resultados indicaram que os drenos torpedo foram mais eficientes se construídos com solo menos úmido, porém sua longevidade foi menor que um ano. Sob o feijoeiro, os drenos torpedo e cobertura morta mantiveram o lençol freático mais profundo e o solo com menor tensão de umidade, mas esses efeitos ocorreram abaixo da zona radicular (15 cm, resultando em baixa produtividade.

    To assess the usefulness of percutaneous treatment of abnormalities of the venous tree in extending the survival of external Thomas shunts (TS). Twelve cases of TS were included in a hemodialysis access fistula dysfunction monitoring program and were followed for up to 48 months. The abnormalities found were treated by percutaneous transluminal angioplasty (PTA) or thrombolysis and PTA. Survival curves and the Kaplan-Meier method were used to calculate the likelihood of primary patency (P1), secondary patency (P2), and overall patency (OP). A total of 61 interventions were performed during the period of follow-up. On 12 occasions the fistula was thrombosed; in the rest, increased venous pressure to 150 mmHg or higher was detected during dialysis. Fistulography was performed after washing the thrombosed fistulas with urokinase, and revealed one or more of the following angiographic signs: 1) a short reduction of more than 50% in lumen caliber in the femoral vein adjacent to the anastomosis, present in 52% of the cases (fig. 1); 2) imaging a "jet" of contrast material at the site of entry of the shunt into the femoral vein (fig. 2), present in 22% of the cases; and 3) a filling defect or "flap" at the same site, owing to hyperplastic tissue or piece of thrombus adhering to the intima, present in 34% of the cases (figs. 3-5). This last-mentioned finding ordinarily gave rise to a "valve" effect, whereby injection into the venous branch was feasible but aspiration from the venous branch was difficult or impossible. PTA was carried out and attained anatomical and functional success in 100% of cases. PI was 58%, 33%, 8%, and 0% at 6, 12, 24, and 36 months, respectively; P2 was 100%, 75%, 58%, and 25%; respectively, at those same times. The comparison of the PI and P2 curves was statistically significant; p < 0.001 (table 1). OP was 83%, 66%, 50% and 41% at 12, 24, 36 and 48 months. The comparison of the PI surgical and OP curves was statistically significant; p < 0

    Full Text Available O preparo mecânico do solo é uma das práticas agrícolas que contribuem para o aumento da perda de carbono via emissão de CO2 do solo (FCO2. Com este trabalho objetivou-se investigar o efeito de três sistemas de preparo do solo na FCO2, temperatura e umidade do solo em área de reforma da cultura de cana-de-açúcar. A área experimental foi constituída de três parcelas, cada uma recebendo um dos preparos do solo: preparo convencional (PC, subsolagem convencional (SC e subsolagem localizada (SL. A FCO2, temperatura e a umidade do solo foram avaliadas durante o período total de 17 dias. A FCO2 foi maior no preparo PC (0,75 g CO2 m-2 h-1. A temperatura do solo não diferiu (p > 0,05 entre as subsolagens: SL (26,2 ºC e SC (25,9 ºC. A umidade do solo foi maior na SL (24%, seguida pela SC (21,8% e preparo PC (18,3%. Apenas no preparo PC foi observada correlação significativa (r = –0,71; p < 0,05 entre FCO2 e a temperatura do solo. O preparo PC apresentou emissão total (2.864,3 kg CO2 ha-1, superior às emissões nas subsolagens: SC (1.970,9 kg CO2 ha-1 e SL (1.707,7 kg CO2 ha-1. A conversão do sistema de preparo PC para a SL diminuiu as emissões de CO2 do solo, reduzindo a contribuição da agricultura para o aumento dos gases de efeito estufa na atmosfera.

    Llewellyn Hilleth Thomas was born in 1903 and died in 1992 at the age of 88. His name is known by most for only two things, Thomas precession and the Thomas-Fermi atom. The many other facets of his career - astrophysics, atomic and molecular physics, nonlinear problems, accelerator physics, magnetohydrodynamics, computer design principles and software and hardware - are largely unknown or forgotten. I review his whole career - his early schooling, his time at Cambridge, then Copenhagen in 1925-26, and back to Cambridge, his move to the US as an assistant professor at Ohio State University in 1929, his wartime years at the Ballistic Research Laboratory, Aberdeen Proving Grounds, then in 1946 his new career as a unique resource at IBM's Watson Scientific Computing Laboratory and Columbia University until his first retirement in 1968, and his twilight years at North Carolina State University. Although the Thomas precession and the Thomas-Fermi atom may be the jewels in his crown, his many other accomplishments add to our appreciation of this consummate applied mathematician and physicist. )

    There are many cardioplegia solutions currently in use for pediatric cardiopulmonary bypass (CPB). The most common being del Nido solution. Another common cardioplegia solution used for pediatric CPB is St. Thomas. In October 2014, Children's Mercy Kansas City changed from the use of modified St. Thomas to del Nido. This study compared rates of post cross-clamp fibrillation requiring defibrillation between del Nido solution and modified St. Thomas solution stratified by weight at Children's Mercy Kansas City. This retrospective study consisted of 394 patients who underwent cardiac surgery requiring cardioplegia between January 1, 2014 and July 31, 2015. The outcome measured was defibrillation upon cross-clamp removal. Statistical significance was determined using Fishers exact test with a two-sided significance level of .05. Incidence of defibrillation post cross-clamp removal was 4.4% in the del Nido group and 26.8% in the St. Thomas group (p Thomas group (p Thomas group (p Thomas group (p 60-kg category had an incidence of defibrillation of 16.7% in the del Nido group and 63% in the St. Thomas group (p Thomas and del Nido cardioplegia solutions. Analyses of weight stratifications demonstrate a decrease in the rate of defibrillation post cross-clamp removal in all categories within the del Nido group.

Em seguida, cultivaram-se as espécies indicadoras de resíduo dos herbicidas no solo: sorgo (Sorghum bicolor para o trifloxysulfuron-sodium e soja (Glycine max para o tebuthiuron. Estas plantas foram colhidas 20 dias após a semeadura, época em que se avaliaram a altura, a MSPA e o grau de intoxicação delas pelos herbicidas. Canavalia ensiformis não sobreviveu até a época de avaliação (60 DAS em solo contaminado pelo tebuthiuron, independentemente do nível de umidade mantido no solo. S. aterrimum sobreviveu quando cultivada em solo com teor de água entre 0,287 e 0,358 kg kg-1 e, quando comparada a C. ensiformis, foi mais eficiente na descontaminação do solo com residual do tebuthiuron. Nos solos contaminados com trifloxysulfuron-sodium ou com tebuthiuron, com o cultivo prévio das espécies remediadoras, o crescimento do sorgo e da soja foi melhor se comparado ao daquelas plantas cultivadas no solo onde não foi feito o cultivo das espécies remediadoras. De maneira geral, a variação da umidade não interferiu no processo de remediação, sendo os efeitos observados no desenvolvimento das espécies remediadoras. O melhor desenvolvimento de C. ensiformis e S. aterrimum foi observado em solo com teor de água mantido em torno de 0,431 kg kg-1; contudo, nesse teor de água, o tebuthiuron é mais facilmente disponibilizado para a solução do solo.This paper aimed to evaluate the effect of soil humidity on Canavalia ensiformis and Stizolobium aterrimum capacity of remediating soil contaminated with tebuthiuron and trifloxysulfuron-sodium.

    Full Text Available Resumo Este artigo analisou o albedo do solosolo abaixo do dossel considerando duas etapas no ciclo hidrológico, a primeira em que o solo estava inundado e a segunda em que o solo estava coberto por serrapilheira acumulada sobre o solo em área inundável de Vochysia divergens Pohl no Pantanal, Brasil. Os valores de αsolo foram calculados pela relação entre as radiação solar global refletida e a incidente medidas abaixo do dossel por meio de estações meteorológicas. A inundação da área ocorreu durante fevereiro a junho e posteriormente houve um aumento gradativo de serrapilheira acumulada sobre o solo. O αsolo variou sazonalmente com maiores valores durante o período seco em que houve um aumento de aproximadamente 42% do αsolo em relação ao período com inundação. Análises de correlação cruzada entre o αsolo e precipitação, umidade do solo e a serrapilheira acumulada sobre o solo explicam em parte a influência direta e/ou indireta sobre o αsolo. A precipitação não influenciou diretamente sobre o αsolo do mês atual, enquanto que a umidade do solo influenciou diretamente sobre o αsolo no mês atual e nos seguintes meses, e a serrapilheira acumulada do solo correlacionou-se positivamente com o αsolo indicando influência direta no mês atual.

O presente trabalho objetivou avaliar o crescimento da mamoneira em solos degradados. Os tratamentos consistiram de solos degradados: subsolo degradado-1, subsolo degradado-2 e área desmatada; quatro doses de fósforo (0, 100, 200, 300 mgkg-1 P, com três repetições. As testemunhas absolutas, sem fósforo, corresponderam ao solo salinizado não corrigido, solo-1 não degradado, solo-2 não degradado e solo de caatinga não desmatada. O solo degradado por sais, o subsolo-2, recebeu correção com gesso agrícola, foi incubado e lavado. Os resultados demonstraram que a análise do subsolo degradado revelou alta salinidade e baixos teores de fósforo e matéria orgânica, o subsolo degradado salino exige correção com gesso para tornar possível o cultivo da mamona em caatinga desmatada e subsolos degradados. As doses de fósforo não promoveram desenvolvimento significativo em mudas de mamona.

    1998-01-01

    The authors extend previous results of a Fermi-Thomas model, describing self-gravitating fermions in their ground state, to a relativistic gravitational theory in Minkowski space. In such a theory the source term of the gravitational potential depends both on the pressure and the density of the fluid. It is shown that, in correspondence of this relativistic treatment, still a Fermi-Thomas-like equation can be derived for the self-gravitating system, though the non-linearities are much more complex. No Fermi-Thomas-like equation can be obtained in the General Relativistic treatment. The canonical results for neutron stars and white dwarfs are recovered and also some erroneous statements in the scientific literature are corrected

    Full Text Available The English Separatist movement provided the background for which John Smyth and Thomas Helwys emerged to reconstitute a biblical ecclesiology. Through the study of the New Testament, they came to the position that infant baptism and covenantal theology could not be the foundation for the New Testament church. Both men embraced believer’s baptism as the basic foundation in which a recovered church should be built. Unfortunately, Smyth defected to the Mennonites, leaving Thomas Helwys to continue the fledging work known as Baptists. This article will examine the life of Thomas Helwys and his contribution to Baptist ecclesiology; it will also review selected literary works that contributed to the recovery of a New Testament church and the founding of Baptist ecclesiology.

    Full Text Available Soil management influences soil cover by crop residues and plant canopy, affecting water erosion. The objective of this research was to quantify water and soil losses by water erosion under different soil tillage systems applied on a typical aluminic Hapludox soil, in an experiment carried out from April 2003 to May 2004, in the Santa Catarina highland region, Lages, southern Brazil. Simulated rainfall was applied during five soybean cropstages, at the constant intensity of 64.0 mm h-1. Treatments were replicated twice and consisted of: i conventional tillage on bare soil - control treatment (CTBS, ii conventional tillage on cultivated soil (CTCS, iii no-tillage on non tilled soil with burned crop residue (NTRB, iv no-tillage in non tilled soil with crop residue desiccated (NTRD, and v no-tillage on four-years interrupted soil tillage with crop residue desiccated - "traditional no tillage" (NTRT. Regardless of soybean cropstages, water losses were the highest for the CTCS than for the untilled soils, while soil losses were considerably higher in the CTCS treatment only until cropstage 3, in cultivated soil treatments. The NTRT was most effective treatment in terms of both water and soil loss reduction. Water infiltration should also be considered, when considering the soil erosion process caused by rainfall and its associated runoff, due to the management systems usually adopted in cultivated fields.O manejo do solo influencia a cobertura superficial pelo resíduo cultural e, juntamente com a cobertura do solo pela copa das plantas, afeta a erosao hídrica.

    Full Text Available O morangueiro é uma cultura importante em vários países, principalmente nos Estados Unidos e na Europa, por suas características sensoriais, propriedades nutritivas e por sua rentabilidade. O cultivo comercial sem solo de morangueiro está bem desenvolvido na Europa, onde tem permitido um aumento da produtividade e qualidade da produção assim como a ampliação da oferta do produto ao longo do ano. Predomina o sistema aberto, em sacolas ou vasos com diferentes tipos de substratos, utilizando-se densidades de 8 a 12plantas m-2. As produtividades obtidas estão entre 5 e 10kg m-2. Para isolar as plantas do solo e facilitar o manejo da cultura, os vasos ou sacolas são suspensos a uma altura entre 0,8 e 1m da superfície do solo. A composição da solução nutritiva é variável, refletindo as diferentes condições produtivas. As mudas são produzidas principalmente em bandejas com substrato, a partir de pontas de estolões obtidas da multiplicação de plantas matrizes provenientes da propagação in vitro. No Brasil, o cultivo sem solo de morangueiro é ainda incipiente e os resultados produtivos e econômicos têm sido insatisfatórios, principalmente por falta de informações de pesquisas capazes de indicar sistemas apropriados de cultivo para as condições locais. É necessário desenvolver sistemas sustentáveis, preferencialmente fechados, combinando alta produtividade e elevada eficiência de utilização da água e dos nutrientes. No presente trabalho, são revisados os principais aspectos da produção em sistemas de cultivo sem solo de mudas e fruta de morangueiro. São descritos a produção de mudas, os sistemas e as soluções nutritivas empregadas em diferentes países. Ao final, são feitas inferências sobre a possibilidade de adoção e geração do sistema de cultivo sem solo apropriado para as condições brasileiras.Strawberry is a very important crop in Europe and USA due to its nutritional and sensorial

    2009-10-01

    Full Text Available Thomas Hardy is usually considered a Victorian writer. Nonetheless, his last novel Jude the Obscure, announced the era of modernity which started with the twentieth century, just before he abandoned fiction to concentrate on poetry. With modernity looming in the background, Jude the Obscure allowed for the rewriting of tragedy. Urban settings have replaced the countryside and all signs of transcendence have vanished from society. This defeat of the divine is nevertheless accompanied by a great number of biblical references. Thomas Hardy quotes and uses the Divine Letter as if to rewrite it rather than to appear faithful to the Word. The text keeps offering itself to the spell of voice: it does so when Job utters words of revolt and then worship, when Jude lets his imagination flow from his lips so that he seems to live on in the text after he is dead, or when the voice of the novelist becomes the voice of a poet.

    Full Text Available The goal of this literature review is to discuss some of the major aspects of the soil seed bank, from its characteristics down to methodological aspects of its determination. Soil seed bank is the reservoir of viable seeds or of vegetative propagules that are present in the soil and that are able to recompose a natural vegetation. In the agroecossystems the soil seed bank is related to weeds, and the knowledge of its size and composition in terms of species can be used in the prediction of future infestations, to built simulation models of population establishment through time and also the definition of soil and cultural management programs, in order to have a rational use of herbicides.O objetivo desta revisão é discorrer sobre alguns pontos importantes no estudo do banco de sementes no solo, desde as sua características até aspectos metodológicos para sua determinação. Denomina-se de banco de sementes a reserva destas ou de propágulos vegetativos viáveis presentes no solo e que são capazes de recompor uma vegetação. Nos sistemas agrícolas o banco está relacionado com o estudo das plantas daninhas; o conhecimento do seu tamanho e das espécies que o compõem poderá ser utilizado na previsão de infestações futuras, na construção de modelos de estabelecimentos populacionais no tempo e consequentemente na definição de programas de manejo de solo e culturais, visando racionalizar a utilização de herbicidas.

    1992-01-01

    The variational extreme condition with respect to statistical distribution of nucleons in momentum space is applied to derive the Euler equation of the nuclear density profile. The resultant Euler equation of the nuclear density profile is proven to be identical with that obtained in the usual Thomas-Fermi theories of a hot nuclear system where the variation is made with respect to the nuclear density profile. A Fermi-Dirac-type distribution appears as a result of variation in the present approach, while it is used as a given expression in obtaining the variation of the nuclear density profile in the usual Thomas-Fermi theories

    2004-01-01

    A simple semiclassical approach, based on the investigation of anti-Stokes line topology, is presented for calculating Regge poles for nonsingular (Thomas-Fermi type) potentials, namely potentials with singularities at the origin weaker than order -2. The anti-Stokes lines for Thomas-Fermi potentials have a more complicated structure than those of singular potentials and require careful application of complex analysis. The explicit solution of the Bohr-Sommerfeld quantization condition is used to obtain approximate Regge poles. We introduce and employ three hypotheses to obtain several terms of the Regge pole approximation

    Full Text Available A análise ambiental, com base nos processos de morfogênese e pedogênese, possibilita informações importantes para a elaboração de políticas públicas visando o uso e ocupação da paisagem de maneira sustentável. Com isso, objetivou-se identificar os diferentes níveis de vulnerabilidade natural à perda de solo do município de Silveira Martins, RS. Foi elaborado um banco de dados espaciais em um ambiente de Sistemas de Informações Geográficas (SIG com auxílio do software Spring. O zoneamento da vulnerabilidade natural à perda de solo foi elaborado com base nas informações referentes à declividade, geomorfologia, geologia e solos de acordo com o grau de vulnerabilidade de cada informação, por meio da álgebra de mapas. Para o território municipal de Silveira Martins identificou-se a ocorrência de cinco classes. Destacam-se as unidades estáveis com predomínio dos processos formadores do solo (38,08% da área municipal, e as unidades moderadamente vulneráveis, prevalecendo os processos erosivos (53,67%. As áreas classificadas como moderadamente vulnerável e vulnerável (8,25%, correspondem a áreas com inclinações superiores a 25º e com formação geológica e geomorfológica menos estáveis. Nas unidades em que predominou a vulnerabilidade natural, sugere-se especial atenção em relação ao meio natural e aos agentes que o influenciam, visando boas práticas sociais associadas às políticas ambientais no processo de tomada de decisões econômicas, possibilitando a valorização e proteção do meio natural.

    Surgeon Major Thomas Heazle Parke (1857-1893) was a doctor from Drumsna, County Roscommon, who after completing his education at the Royal College of Surgeons in Ireland joined the British army as a medical officer. After several years of serving in Ireland and Egypt, he volunteered to be medical officer of the Emin Pasha Relief Expedition of 1887-1889. This was to become Henry Morton Stanley's largest, longest and most controversial African expedition. The epic journey saw Stanley, his eight European officers and 800 African porters take almost 3 years to cross the African continent from West to East via the Congo River, Southern Sudan and Uganda. During this time, Parke had to single-handedly deal with the myriad diseases and injuries that beset the expedition's members. Barely 200 of the Zanzibari, Sudanese and Somali porters survived, and two British officers also perished. In completing the expedition, Parke became the first Irishman to cross Africa, and he had also become the first European to lay eyes on the ' Mountains of the Moon ' or ' Ruwenzori '. He returned home to great acclaim, and was bestowed copious honours and fellowships. His account of the expedition, My Experiences in Equatorial Africa , was a bestseller. However, his own health never recovered from the hardships of his time in Africa, and he died suddenly in 1893. His statue stands outside the Natural History Museum in Dublin. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017. All rights reserved.

A qualidade física do solo é afetada negativamente na posição rodado sob o manejo com amendoim forrageiro e nas posições rodado e entrerodado no manejo tradicional da vegetação espontânea com herbicida pós-emergente.The traffic of agricultural machinery and soil compaction occur near the canopy of citrus trees, which increases soil physical restrictions to root growth. Soil management strategies include the use of permanent groundcover in the interrows of orange tree plantations, although the effects of these practices on the soil physical quality are largely unknown. The objective of this study was to assess the impact of groundcover management systems on some indicators of soil physical quality for orange tree orchards. The study was performed in a long-term experiment with 'Pêra' orange grafted onto 'Rangpur' lime combined with groundcover systems, established in 1993, in the Alto Paraná county, northwestern Paraná state, Brazil, in a Typic Paleudult with a sandy surface horizon. Bahiagrass (Paspalum notatum or perennial peanut (Arachis pintoi groundcover treatments were compared with the usual management in which weeds are controlled by post-emergence herbicide. The experimental design consisted of randomized blocks with three replications. In May 2003, soil samples were collected from under and between the wheel tracks. The following indicators were assessed in undisturbed soil samples from the mid 0-15 cm layer: water content at field capacity, total porosity and bulk density. The data were used to estimate soil aeration and water storage capacity indicators. Disturbed soil

    Full Text Available O conhecimento do comportamento de herbicidas no ambiente, sobretudo no solo, permite a predição de possíveis impactos do seu uso em sistemas agrícolas. Com o intuito de avaliar a sorção do herbicida imazapyr no solo, foi realizado um experimento, utilizando sorgo (Sorghum bicolor como planta bioindicadora. A sorção do imazapyr foi avaliada em areia lavada e em três solos, com as seguintes texturas: muito argilosa, franco-argilo-arenosa e areia-franca, provenientes, respectivamente, das cidades de Sete Lagoas, João Pinheiro e Rio Casca, em Minas Gerais. Foram determinados: o valor de I50 (dose que inibiu 50% no acúmulo de massa seca da planta-teste e a relação de sorção [RS = (I50 solo -I 50 areia/I50 areia]. Os valores de I50 observados foram: 29,41; 10,20 e 7,33 mg kg-1, e a relação de sorção (RS: 9,77; 2,73 e 1,68, respectivamente para os solos muito argiloso, franco-argilo-arenoso e areia franca. O herbicida imazapyr apresentou a seguinte ordem de sorção nos substratos: muito argiloso > franco-argilo-arenoso > areia-franca > areia lavada. Em solos arenosos e com baixos teores de matéria orgânica, a baixa sorção do imazapyr predispõe o produto à lixiviação no perfil do solo, podendo contaminar mananciais de águas subterrâneas.Knowledge about herbicide behavior in the environment, especially in soil, allows predicting possible impacts caused by its use in agricultural systems. An experiment using Sorghum bicolor as a bio-indicator was carried out to evaluate imazapyr sorption in soil. Sorption was evaluated in washed sand and in soils of 3 different textures: very clayed, sandy clayed loam and sandy loam, respectively from Sete Lagoas, João Pinheiro and Rio Casca - Minas Gerais. The value of I50, which inhibits 50% of dry biomass accumulation of the test-plant, and sorption relation (SR = I50 soil - I50 sand/I50 sand were determined. I50 values observed were 29.41, 10.20 and 7.33 mg kg-1 and SR values were 9

  3. Urbanization and the Resulting Peripheralization in Solo Raya, Indonesia

    2018-02-01

    Dynamic urbanization in Solo Raya, a local term for Surakarta Metropolitan, amongst rapid regional based-urbanization in Indonesia, shows the unbalance pattern of growth. A number of Surakarta City’s peripherals become the newly growing area which is characterized by a well-facilitated region, while the former urbanized areas next to the city center present the declining process. Different socioeconomic development triggers a unique mosaic of socio-spatial pattern, on which the phenomena of peripheralization could be investigated. Urban investment that boosted by the political will of both the national and local government has led to a shift in demographic condition. A relatively massive in-migration has been attracted to the peripheral and creates the new landscape of urban-rural society. Complex dynamic of metropolitan growth and the resulting peripheralization reminds that socio-spatial pattern calls the challenges for managing the rapid change of land use and space use. The pattern of urbanization that differs upon the surrounding areas of Surakarta City would be interesting to be explored. This paper will discuss the conceptual framework of peripheral urbanization and the methodological approach. It is actually the part of ongoing research on peripheralisation in Solo Raya.

    The incidence of postoperative thrombocytopenia after aortic valve replacement with the Freedom Solo bioprosthesis remains unclear. This propensity-matched study was carried out to evaluate the incidence and clinical impact of thrombocytopenia in patients receiving the Freedom Solo bioprosthesis. Patients who underwent aortic valve replacement with a Freedom Solo or Carpentier-Edwards Perimount pericardial prosthesis at our institution between 2006 and 2008 were screened retrospectively. Exclusion criteria included double valve replacement, redo surgery, and active endocarditis. Two hundred six patients were considered eligible for this analysis. Using propensity scores 36 matched pairs of patients with a Freedom Solo or Perimount bioprosthesis were obtained. The primary end point was the occurrence of postoperative thrombocytopenia. Secondary end points were postoperative thromboembolic or hemorrhagic events and 30-day mortality. Before matching, severe thrombocytopenia (Solo bioprosthesis and 1% with a Perimount bioprosthesis (p Solo (p Solo and Perimount bioprostheses, respectively (p Solo implantation.

Objetivou-se com este trabalho avaliar os teores de K não-trocável, K trocável e K solúvel em doze solos do Estado da Paraíba, na ausência e na presença de fertilização potássica, e correlacioná-los com as características químicas, físicas e mineralógicas desses solos. O estudo constou de 60 tratamentos, sendo 12 solos e cinco doses de K (0; 50; 100; 200 e 300 mg dm-3 na forma de cloreto de potássio, com três repetições. Após receberem os tratamentos, os solos foram incubados por um período de 21 dias, e em seguida, uma sub-amostra de 0,2 dm³ de cada solo foi retirada para determinação dos teores de K não-trocável, K trocável e K solúvel. Os solos formados sob clima semiárido foram os solos que apresentaram as maiores reservas de K não-trocável. Solos com maior proporção de mica e minerais do tipo 2:1 na fração argila apresentaram os maiores teores de K não-trocável e K trocável. Independente do grupo de solos, os teores de silte apresentaram correlação elevada com os teores de K não-trocável e de K trocável. Nos solos mais desenvolvidos, não foi evidenciada fixação de K proveniente do fertilizante. Porém, nos solos menos desenvolvidos, a fixação de K ficou evidenciada pela pequena quantidade de K recuperada pelo extrator acetato de amônio nos solos mais argilosos e, principalmente, naqueles com predominância de minerais do tipo 2:1 e mica.

    2017-11-01

    Peter of Tilleberi (Tilbury), later known as bishop Thomas of Wroclaw, after completing his studies (in Bologna or in Montpellier) worked as a physician in northern Italy and probably in Spain. Later through Germany and Bohemia, he came to Wroclaw in 1336 where he joined the Order of St. Dominic. In 1352, Thomas was made an auxiliary bishop of the diocese of Wroclaw. After the episcopal consecration, Thomas stopped living in the abbey, but all the time he was well known both as a priest and physician. He is known as an author of several treatises on medical sciences. His most important work entitled Michi competit (i.e. It suits me) is composed of four parts: Regimen sanitatis (i.e. Hygiene), Aggregatum (i.e. Aggregation), Antidotarium (i.e. Medicine directory) and Practica medicinalis (i.e. Medical practices). Moreover, he is the author of other treatises including, for example, De phlebotomia et de iudiciis cruoris (i.e. On phlebotomy and blood content) and De urinis (i.e. On urine). Some Polish scientists claim that bishop Thomas of Wroclaw with his knowledge and industriousness functioned as a university faculty of medicine even though the University of Cracow had not been established yet.

    2014-01-01

    We describe a case of a 76-year old male who presented with progressive dyspnoea. He underwent an aortic valve replacement with a Freedom SOLO bioprosthesis 6 years ago. Transthoracic echocardiography showed a moderate-to-severe leakage of the Freedom SOLO bioprosthesis. During surgical reintervention, a partial tear of the left coronary cusp was seen from the commissure of the right coronary cusp to its base. After radiographic and microscopic examination, no clear cause was found for the failure of this Freedom SOLO bioprosthesis. To our knowledge, this is the third failure of a Freedom SOLO bioprosthesis reported in the literature. When the long-term follow-up of the Freedom SOLO bioprosthesis is available, it has to be compared with other bioprosthesis for long-term durability.

    2017-04-01

    The objective of this study is to document the health profile of 252 African-American grandparents raising their grandchildren solo, compared with 1552 African-American single parents. The 2012 Behavior Risk Factor Surveillance System is used to compare the specific physical and mental health profiles of these two family groups. The findings suggest solo grandparents have prevalence of many health conditions, including arthritis (50.3 %), diabetes (20.1 %), heart attack (16.6 %) and coronary heart disease (16.6 %). Logistic regression analyses suggest that solo grandparents have much higher odds of several chronic health disorders in comparison with single parents, but this difference is largely explained by age. Although solo grandparents have good access to health care insurance and primary care providers, a substantial percentage (44 %) rate their health as fair or poor. Practice interventions to address African American solo grandparents' health needs are discussed.

  19. Interplay between Solo and keratin filaments is crucial for mechanical force-induced stress fiber reinforcement.

    Mechanical force-induced cytoskeletal reorganization is essential for cell and tissue remodeling and homeostasis; however, the underlying cellular mechanisms remain elusive. Solo (ARHGEF40) is a RhoA-targeting guanine nucleotide exchange factor (GEF) involved in cyclical stretch-induced human endothelial cell reorientation and convergent extension cell movement in zebrafish gastrula. In this study, we show that Solo binds to keratin-8/keratin-18 (K8/K18) intermediate filaments through multiple sites. Solo overexpression promotes the formation of thick actin stress fibers and keratin bundles, whereas knockdown of Solo, expression of a GEF-inactive mutant of Solo, or inhibition of ROCK suppresses stress fiber formation and leads to disorganized keratin networks, indicating that the Solo-RhoA-ROCK pathway serves to precisely organize keratin networks, as well as to promote stress fibers. Of importance, knockdown of Solo or K18 or overexpression of GEF-inactive or deletion mutants of Solo suppresses tensile force-induced stress fiber reinforcement. Furthermore, knockdown of Solo or K18 suppresses tensile force-induced RhoA activation. These results strongly suggest that the interplay between Solo and K8/K18 filaments plays a crucial role in tensile force-induced RhoA activation and consequent actin cytoskeletal reinforcement. © 2016 Fujiwara et al.

    Solo and small practices are facing growing pressure to consolidate. Our objectives were to determine (1) the percentage of family physicians in solo and small practices, and (2) the characteristics of and services provided by these practices. A total of 10,888 family physicians seeking certification through the American Board of Family Medicine in 2013 completed a demographic survey. Their practices were split into categories by size: solo, small (2 to 5 providers), medium (6 to 20 providers), and large (more than 20 providers). We also determined the rurality of the county where the physicians practiced. We developed 2 logistic regression models: one assessed predictors of practicing in a solo or small practice, while the other was restricted to solo and small practices and assessed predictors of practicing in a solo practice. More than one-half of respondents worked in solo or small practices. Small practices were the largest group (36%) and were the most likely to be located in a rural setting (20%). The likelihood of having a care coordinator and medical home certification increased with practice size. Physicians were more likely to be practicing in small or solo practices (vs medium-sized or large ones) if they were African American or Hispanic, had been working for more than 30 years, and worked in rural areas. Physicians were more likely to be practicing in small practices (vs solo ones) if they worked in highly rural areas. Family physicians in solo and small practices comprised the majority among all family physicians seeking board certification and were more likely to work in rural geographies. Extension programs and community health teams have the potential to support transformation within these practices. © 2016 Annals of Family Medicine, Inc.

  1. The poor in the Epistle of James and the Gospel of Thomas

    1997-12-01

    Full Text Available This study explores similarities in the thought world of the Epistle of James and the Gospel of Thomas. Particular attention is devoted to the role that the 'poor' and 'poverty' play in both documents. For the Epistle of James it is 'the poor in the world that God has chosen to be rich in faith and heirs of the kingdom' (Ja 2:5.  In a similar vein, in the Gospel of Thomas the kingdom is promised to those who have embraced the poverty of a radical life-style: 'Blessed are the poor, for yours is the kingdom of heaven' (GTh 54. This outlook betrays a basic ethos adopted toward the world. In both the Epistle of James and the Gospel of Thomas the relationship to the world ultimately determines one's relationship to the kingdom or to God. For the Epistle of James the very definition of religion demands that one keep 'oneself unstained from  the world' (Ja 1 :27 and that 'friendship with the world' is enmity with God (Ja 4:4. For the Gospel of Thomas the rejection of the world involves a radical ethos that embraces an intinerant life ('Be passersby' [GTh 42J, which includes a rejection of wealth (GTh 63.'If you do not abstain from the world, you will not find the kingdom' (GTh 27. It is argued that the Gospel of Thomas and the Epistle of James reflect traditional sayings that endorse a similar ethos of radical discipleship.

    The measurement of the neutron electric form factor, GEn, will allow us to solve indirectly for the quark charge distribution inside of the neutron. With the equipment at Jefferson Lab we have measured GEn at four momentum transfer values of Q**2 at 1.3, 2.4 and 3.4 (GeV/c)**2 using a polarized electron beam and polarized Helium target. The scattered electrons off of the Helium target are detected in the BigBite spectrometer and the recoiling neutrons from the Helium are detected in the Neutron Arm, which is composed of an array of scintillators. The main focus of this thesis will be devoted to the geometry, timing and energy calibrations of the Neutron Arm

    The aim of the current trial was to evaluate the learning curve of access creation through solo ultrasonography (US)-guided percutaneous nephrolithotomy (PCNL), and clarify the technical details of the procedure. We evaluated the first 240 solo US-guided PCNLs performed by one surgeon at our institution. The data including the puncture procedure, access characteristics, access-related complications and stone-free rates were assessed in four sequential groups. The puncture duration and number of times decreased from a mean of 4.4 min and 2.1 times for the first 60 patients to 1.3 min and 1.2 times for the last 60 patients. There was a significant decrease from 3.7 min and 1.8 times for the 61th-120th patients to 1.5 min and 1.3 times for the 121th-180th patients. All of the access-related severe bleeding appeared in the first 120 patients, while perforations only occurred in the first 60 patients. The stone-free rates were 68.3, 83.3, 90.0, and 93.3% for the four sequential groups. The increase in experience lead to an improvement in the puncture duration and times, which accompany with better stone-free rates and lower complications. We propose that 60 operations are sufficient to gain competency, and a cutoff point of 120 operations will allow the surgeon to achieve excellence in the solo US-guided PCNL.

    2015-02-01

    For the purpose to measure a rotation angle around the axis of an object, a non-contact rotation angle measurement method based on solo camera was promoted. The intrinsic parameters of camera were calibrated using chessboard on principle of plane calibration theory. The translation matrix and rotation matrix between the object coordinate and the camera coordinate were calculated according to the relationship between the corners' position on object and their coordinates on image. Then the rotation angle between the measured object and the camera could be resolved from the rotation matrix. A precise angle dividing table (PADT) was chosen as the reference to verify the angle measurement error of this method. Test results indicated that the rotation angle measurement error of this method did not exceed +/- 0.01 degree.

We aimed to evaluate the effects of coating propolis extract on the physicochemical characteristics of papaya stored at room temperature. Solo papayas cv. 'Golden' were randomly divided into five postharvest treatment groups, three forms of dip-coating (70% alcohol, hydroalcoholic extract of propolis to 2.5%, and hydroalcoholic extract of propolis to 5% and two controls (one uncoated and one with refrigerated uncoated fruits. The weight loss, firmness, soluble solids (SS, titratable acidity (TA, SS/TA, and hydrogen potential (pH were evaluated at the intervals of 4 days every 12th storage day. Sensory analysis was performed on the 4th day of storage of papayas and evaluated by untrained through the acceptance testing. Treatments “refrigerated”, “propolis 2.5%”, and “5% propolis” presented with the lowest weight loss. The firmness level for treatment propolis 5% was superior to that of control, alcohol, and 2.5% propolis treatments. The SS was greater for propolis 5% treatment, which only differed from the alcohol treatment. The TA and SS/TA did not vary with the treatments, but with the storage time. The pH of refrigerated papaya showed significant differences in relation to other treatments. The fruits subjected to refrigerated treatment presented with chilling injury. Papayas coated with propolis extract showed sensory acceptability similar to that in other treatments on the 4th day of storage. The coating of propolis extract is a promising alternative for the control of weight loss and for the maintenance of firmness in Solo papaya cv. 'Golden'.

Internal (self-contempt, positive self-evaluation and external criteria (musical rewards, successful solo performances, successful auditions of efficiency of solo music performance were taken into consideration. The research was grounded on studies from the field of sports psychology and on the few studies that were carried out in the field of psychology of music. The research was conducted on 94 students of Music Academy, grouped by gender and field of study (instrumentalists, solo vocalists and composers vs. students of music teaching. The symptoms of performance anxiety were measured by a part of the Performance Anxiety Questionnaire, and efficiency of solo music performance by the Efficiency of Music Performance Questionnaire. Both questionnaires were developed for the purpose of the study. The results reveal the interrelationship between the internal criteria of efficiency in solo music performance and performance anxiety. On the other hand, only trends of correlation were established between performance anxiety and the external criteria of solo music performance. The research findings imply the important role of cognition as a mediator between performance anxiety and performance efficiency.

Foi verificado que a aplicação do composto de lixo promoveu o aumento da CE dos solos. Todavia, esse efeito foi inferior àquele causado pelos adubos minerais. Os maiores valores de CE (> 2 dS m-1 foram causados pelas aplicações do composto + calcário + adubo nos solos ácidos e do composto + adubo + gesso nos solos alcalinos. Porém, quanto maior a capacidade de troca catiônica (CTC inicial dos solos ácidos e pH inicial dos solos alcalinos, menores foram os efeitos dos tratamentos sobre o incremento da CE. A aplicação do composto promoveu, também, o aumento do pH e a redução da acidez potencial. Esse efeito do composto foi, em média, superior àquele causado pela aplicação do calcário. A aplicação conjunta do composto e calcário promoveu um efeito aditivo de seus efeitos isolados sobre o pH e acidez potencial do solo. A adição dos adubos minerais tendeu a reduzir o pH por causa da acidificação residual da uréia. Esse efeito foi bem evidente nos solos alcalinos. O aumento do pH e da CE foi acompanhado por uma diminuição na diferença entre os valores de pH medido em CaCl2 e em água, notadamente nos solos ácidos. A aplicação do composto de lixo para melhorar a acidez do solo, manejando-se adequadamente o calcário e adubos minerais nos solos ácidos ou gesso nos solos alcalinos, parece ser uma prática agrícola viável.

    Full Text Available City of Surakarta, known as Solo City is one of cities in Central Java Province traversed by Bengawan Solo River. Heavy rainfall in upstream area of Bengawan Solo River causes increase in high water level at downstream. Bengawan Solo River will be higher than water level in drainage system which may induce a backwater flow. Since Colonization era, the government has built dikes and barrages against backwater flow and inundation problem. One of the barrages was Demangan Barrage dividing river flow into Bengawan Solo River and Pepe River. It was equipped with total capacity pump of 12,3 m3/s. The inundation is not only caused by the backwater flow coming from Bengawan Solo River, but also surface runoff as the result of the excess rainfall which cannot be drained gravitationally to the main river if the gate was closed. Therefore, comprehensive study combining hydrology and hydraulics analysis is highly needed in order to achieve more effective flood control management. Hydrology analysis was done to estimate the direct runoff hydrograph from catchment area in Solo City to downstream of Pepe River. While in hydraulics case, hydraulic parameter in downstream of Pepe River influenced by Bengawan Solo River stream was analyzed. Both studies were simulated using software HEC-RAS 4.1.0 version. The simulation considered drainage channel, gate, pump system and dike in Pepe River downstream. Simulation using 10 years of return period in Solo City and average annual water level in Bengawan Solo River showed that Pepe River can flow through the gate, while the highest water level is still below the dike. Simulation considering 10 years of return period, water level hydrograph of Bengawan Solo River, existing pump, and gate operation inferred that Pepe River surpassed top of dike. Capacity of required pump should be more than 168,3 m3/s in order to pass 10 years of return period. By combining operational of existing pump and dike elevated up to +87,63 m

Utilizando a câmara de membrana de pressão de Richards, foram determinados os teores de sódio deslocado a diferentes tensões. Uma baixa correlação entre a condutividade hidráulica e a porcentagem de sódio intercambiável foi encontrada. A aplicação da solução de sulfato de cálcio apresentou um efeito benéfico sobre a condutividade hidráulica do solo saturado, exceto quando processos irreversíveis de dissolução mineral ocorreram. Este efeito esteve associado ao pH ou ao conteúdo de carbonatos na solução percolante.The purpose of this work was to evaluate the effect of exchangeable sodium percentage and electrolite concentration of percolating water, on the hydraulic conductivity of a Noncalcic Brown Soil of the region of the River Salitre-Ba, Brazil.

  2. Thomas Mann's "Tobias Mindernickel" in Light of Sartre's "Being-for-Others"

    Directory of Open Access Journals (Sweden)

    Beth Bjorklund

    1978-01-01

    Full Text Available Sartre's analysis of "Being-for-Others" in Being and Nothingness describes the Self-Other relationship as essentially one of conflict, with the Self attempting either to dominate or to be dominated by the Other. Subject-Object relations are a common theme also in the early works of Thomas Mann, who gives artistic expression to many of the same problems which Sartre later formalized in a philosophical theory. The sado-masochistic character, which is portrayed in several of Thomas Mann's narratives, receives its strongest expression in the story "Tobias Mindernickel," which is here singled out for analysis. Humiliation gives rise to aggression, as the protagonist feels both an attraction and a repulsion for his surrogate lover, a dog. The interpersonal relationships revealed here serve as paradigmatic illustration of Sartre's theory of "Concrete Relations with Others."

    A recently completed Thomas-Fermi model of nuclei is described. Six adjustable parameters of the effective nucleon-nucleon interaction were fitted to the shell-corrected binding energies of 1654 nuclei and to the diffuseness of the nuclear surface. The model is then successful in reproducing nuclear sizes, and only small deviations are found between calculated and measured fission barriers of 36 nuclei. The model is applied to the prediction of fission barriers of light elements, to drip-line nuclei like 82 Sn and 170 Sn, to the properties of nuclear and neutron matter and to nuclear bubble configurations with Z 2 /A ∼ 100. The relation of a Thomas-Fermi theory to the Droplet and Liquid Drop models is illustrated

    The charge transfer process in the collision of fast protons with hydrogen molecules is theoretically investigated using the second-order Born approximation with correct boundary conditions. In addition to two first-order terms, the present calculations include the three second-order terms which correspond to the Thomas two-step scattering mechanisms. The interference effects, due to the scattering of the particles from two atomic centres, on the electron capture differential cross sections vary significantly with the orientation of the molecule and with the impact energy. After the averaging over all molecular orientations the interference patterns disappear but the Thomas peak becomes more pronounced. These patterns are also apparent in the differential cross sections as a function of the angle between the molecular axis and the incident beam direction. The integrated cross sections are calculated and the results are compared with available experimental data.

    This new edition of Thomas Kuhn's Revolution marks the 50th anniversary of the publication of Kuhn's most influential work. Drawing on the rich archival sources at MIT, and engaging fully with current scholarship, James Marcum provides the historical background to the development of The Structure of Scientific Revolutions. Exploring the shift Kuhn makes from a historical to an evolutionary philosophy of science and examining Kuhn's legacy in depth, Marcum answers key questions: What exactly was Kuhn's historiographic revolution and how did it come about? Why did it have the impact it did? What will its future impact be for both academia and society? Marcum's answers build a new portrait of Kuhn: his personality, his pedagogical style and the intellectual and social context in which he practiced his trade. Thomas Kuhn's Revolution shows how Kuhn transcends the boundaries of the philosophy of science, influencing sociologists, economists, theologians and even policy makers and politicians.

  8. Thomas Aquinas on the Soul: Old problems, New Solutions. Guiding Premises for a Thomistic Synthesis

    Yevgeniy Shilov

    2012-12-01

    Full Text Available This article examines two main approaches to the doctrine of the soul: that of Plato and that of Aristotle. Each of these approaches had its own development and its own interpretations. Plato and his school was more important during the Middle Ages. Through the neo-platonic philosophers it reached Saint Augustine and became a part of the western cultural and religious heritage until finally it was taken up by member of the Franciscan order - Roger Bacon and Bonaventure. But this paradigm could not solve a host of problems connected with the soul and many of them remained unresolved. The end of the twelfth century brought the growth of the universities and the teaching of Aristotle - a new paradigm - transmitted by the Arabic philosophers which was rediscovered by the West. Two commentators on Aristotle - Averroes and Avicenna -were the most important for the West, especially since Avicenna exerted a great influence on Albert the Great. But both Plato and Aristotle, when taken separately, proved to be quite useless in resolving certain problems. But Thomas Aquinas was able to splice the Gordian knot concealing a solution to the problem of the soul. By combining the psychology of Plato with the metaphysics of Aristotle, Thomas succeeded in creating a new concept of the human person. The author of this article has tried to explain the difficulties which faced Thomas and the way in which Thomas was able to resolve a problem which had troubled philosophy through the ages - the problem of reconciling Plato with Aristotle and finding a way to make their conflicting philosophies agree with each other

    We study the ionization problem in the Thomas-Fermi-Dirac-von Weizsäcker theory for atoms and molecules. We prove the nonexistence of minimizers for the energy functional when the number of electrons is large and the total nuclear charge is small. This nonexistence result also applies to external potentials decaying faster than the Coulomb potential. In the case of arbitrary nuclear charges, we obtain the nonexistence of stable minimizers and radial minimizers.

    2012-05-01

    Full Text Available This paper aims to present some considerations about the importance of reading to the development of the ethics conceptions of Thomas Aquinas (1224 - 5? / 1274. At the dawn of the thirteenth century, the townspeople of Medieval West created a new institution designed for knowledge and education: the University. In it, teachers and disciples were debating key issues for the new society using mainly texts of Ancient Philosophy and Christians, but also Arab and Jewish writings. The literacy forms used encompassed mainly lectio and disputatio , and counteracted by distinct theoretical bases, those thinkers eventually recreated the summa , in a original and fundamental form to the philosophical elaboration of that time. To discuss the importance of reading in the formulation of the concept of ethics in the medieval university, we will present some characteristics of the production of knowledge in the thirteenth century linked to its historical context and then discuss some ethical considerations of Thomas Aquinas, one of the most prominent authors of that period. Considering the limits of this article, only one text, “The object of charity” based on Aquinas major work, the Summa of Theology, will be discussed in depth. Preliminarily, it is possible to state that as well as the reading of classical authors by Thomas Aquinas and other masters of the thirteenth century, helped them develop knowledge about ethics conforming to their time, historical reading of these authors helps in the understanding of today.

    The linear and nonlinear properties of dust-acoustic waves are investigated in a collisionless Thomas-Fermi magnetoplasma, whose constituents are electrons, ions, and negatively charged dust particles. At dust time scale, the electron and ion number densities follow the Thomas-Fermi distribution, whereas the dust component is described by the classical fluid equations. A linear dispersion relation is analyzed to show that the wave frequencies associated with the upper and lower modes are enhanced with the variation of dust concentration. The effect of the latter is seen more strongly on the upper mode as compared to the lower mode. For nonlinear analysis, we obtain magnetized Korteweg-de Vries (KdV) and Zakharov-Kuznetsov (ZK) equations involving the dust-acoustic solitary waves in the framework of reductive perturbation technique. Furthermore, the shock wave excitations are also studied by allowing dissipation effects in the model, leading to the Korteweg-de Vries-Burgers (KdVB) and ZKB equations. The analysis reveals that the dust-acoustic solitary and shock excitations in a Thomas-Fermi plasma are strongly influenced by the plasma parameters, e.g., dust concentration, dust temperature, obliqueness, magnetic field strength, and dust fluid viscosity. The present results should be important for understanding the solitary and shock excitations in the environments of white dwarfs or supernova, where dust particles can exist.

    The linear and nonlinear properties of dust-acoustic waves are investigated in a collisionless Thomas-Fermi magnetoplasma, whose constituents are electrons, ions, and negatively charged dust particles. At dust time scale, the electron and ion number densities follow the Thomas-Fermi distribution, whereas the dust component is described by the classical fluid equations. A linear dispersion relation is analyzed to show that the wave frequencies associated with the upper and lower modes are enhanced with the variation of dust concentration. The effect of the latter is seen more strongly on the upper mode as compared to the lower mode. For nonlinear analysis, we obtain magnetized Korteweg-de Vries (KdV) and Zakharov-Kuznetsov (ZK) equations involving the dust-acoustic solitary waves in the framework of reductive perturbation technique. Furthermore, the shock wave excitations are also studied by allowing dissipation effects in the model, leading to the Korteweg-de Vries-Burgers (KdVB) and ZKB equations. The analysis reveals that the dust-acoustic solitary and shock excitations in a Thomas-Fermi plasma are strongly influenced by the plasma parameters, e.g., dust concentration, dust temperature, obliqueness, magnetic field strength, and dust fluid viscosity. The present results should be important for understanding the solitary and shock excitations in the environments of white dwarfs or supernova, where dust particles can exist

    Full Text Available O uso do solo nem sempre dá lugar a um novo sistema ecológico sustentável, seja de lavouras, seja de pastagens. Com isso, solos utilizados intensamente e de forma inadequada são levados à degradação. Nesse sentido, este trabalho teve como objetivo estudar a influência do lodo de esgoto na recuperação de propriedades físicas de um Latossolo Vermelho degradado, cultivado há 2,5 anos com eucalipto (Eucalyptus citriodora Hook e braquiária (Brachiaria decumbens no município de Selvíria, MS. O delineamento experimental utilizado foi em blocos casualizados com seis tratamentos e quatro repetições. Os tratamentos foram: 1-vegetação de Cerrado; 2-solo exposto sem tratamento para recuperação; 3-solo cultivado com eucalipto e braquiária sem uso do lodo de esgoto e adubação mineral; 4-solo cultivado com eucalipto e braquiária com adubação mineral; 5-solo cultivado com eucalipto e braquiária com uso de 30 Mg ha-1 de lodo de esgoto; e 6-solo cultivado com eucalipto e braquiária com uso de 60 Mg ha-1 de lodo de esgoto. Nas camadas do solo de 0,00-0,05; 0,05-0,10; 0,10-0,20; e 0,20-0,30 m, foram estudadas as propriedades físicas do solo: macroporosidade, microporosidade; porosidade; e densidade do solo. Na braquiária foram avaliadas as matérias verde e seca e, no eucalipto, a altura média de planta e o DAP (diâmetro à altura do peito. Concluiu-se que o solo estudado está sendo recuperado por meio dos tratamentos estabelecidos. Dentre eles, destacam-se os tratamentos com a utilização do lodo, que influenciaram as propriedades físicas do solo, proporcionaram mais rendimentos de matérias verde e seca da braquiária e promoveram maior crescimento das plantas de eucalipto. O crescimento vegetal, a densidade do solo, a porosidade total e a macroporosidade foram os melhores indicadores da recuperação do solo.The soil use not always result in an ecological sustainable system.

A extração da silica com solução 0,0025M de cloreto de cálcio evitou a dispersão dos solos e forneceu resultados em média apenas 8% menores do que a silica solúvel em água. Os resultados variaram de 2,2 a 92,2 ppm de SiO2. Verificou-se que, para solos com teores semelhantes de argila, os teores de silica solúvel foram maiores para solos com horizonte B textural, quando comparados com solos de horizonte B latossólico. Dentro dos agrupamentos de solos com horizonte B textural e horizonte B latossólico, os teores de silica solúvel foram maiores para os solos mais argilosos. Não foi observada relação entre silica solúvel e o pH dos solos.The extraction of soluble silica of soils with 0.0025M calcium chloride solution avoided dispersion of clay and results were on the average only 8% lower than water soluble silica. The results for surface and B2 horizons of 44 soil profiles of the State of São Paulo varied between 2.2 and 92.9 ppm of SiO2. For soils with similar clay contents, soluble silica was higher for soil with argillic B horizons as compared with soils with oxic B horizons. Within each group of soils, higher soluble silica results were associated with higher clay contents. Soluble silica apparently was not related to soil pH.

    Full Text Available The modified Thomas test was developed to assess the presence of hip flexion contracture and to measure hip extensibility. Despite its widespread use, to the authors’ knowledge, its criterion reference validity has not yet been investigated. The purpose of this study was to assess the criterion reference validity of the modified Thomas test for measuring peak hip extension angle and hip extension deficits, as defined by the hip not being able to extend to 0º, or neutral. Twenty-nine healthy college students (age = 22.00 ± 3.80 years; height = 1.71 ± 0.09 m; body mass = 70.00 ± 15.60 kg were recruited for this study. Bland–Altman plots revealed poor validity for the modified Thomas test’s ability to measure hip extension, which could not be explained by differences in hip flexion ability alone. The modified Thomas test displayed a sensitivity of 31.82% (95% CI [13.86–54.87] and a specificity of 57.14% (95% CI [18.41–90.10] for testing hip extension deficits. It appears, however, that by controlling pelvic tilt, much of this variance can be accounted for (r = 0.98. When pelvic tilt is not controlled, the modified Thomas test displays poor criterion reference validity and, as per previous studies, poor reliability. However, when pelvic tilt is controlled, the modified Thomas test appears to be a valid test for evaluating peak hip extension angle.

    Selective memorising of isolated facts or reproducing what is thought to be required - the surface approach to learning - is not the desired outcome for a dental student or a dentist in practice. The preferred outcome is a deep approach as defined by an intention to seek understanding, develop expertise and relate information and knowledge into a coherent whole. The aim of this study was to investigate whether the structure of observed learning outcome (SOLO) taxonomy could be used as a model to assist and promote the dental students to develop a deep approach to learning assessed as learning outcomes in a summative assessment. Thirty-two students, participating in course eight in 2007 at the Faculty of Odontology at Malmö University, were introduced to the SOLO taxonomy and constituted the test group. The control group consisted of 35 students participating in course eight in 2006. The effect of the introduction was measured by evaluating responses to a question in the summative assessment by using the SOLO taxonomy. The evaluators consisted of two teachers who performed the assessment of learning outcomes independently and separately on the coded material. The SOLO taxonomy as a model for learning was found to improve the quality of learning. Compared to the control group significantly more strings and structured relations between these strings were present in the test group after the SOLO taxonomy had been introduced (P SOLO taxonomy is recommended as a model for promoting and developing a deeper approach to learning in dentistry.

    Stentless biological valves have proven advantages in hemodynamic performance and left ventricular function compared to stented biological valves. Following a marked postoperative fall in the platelet count of patients after implantation of the Freedom SOLO valve, the study aim was to confirm clinical observations that this effect was more severe in patients receiving Freedom SOLO valves than in those receiving St. Jude Medical (SJM) mechanical aortic valves. Preoperative and postoperative platelet counts were compared in two groups of patients who underwent aortic valve replacement (AVR) without any concomitant procedures between January and December 2007. Patients received either a Freedom SOLO valve (n = 28) or a SJM mechanical valve (n = 41). Mean values of platelet counts were compared using three multiple linear regression models. Platelet counts were significantly lower in the Freedom SOLO group than in the SJM group from the first postoperative day (POD 1) up to POD 6 (p SOLO group the platelet count fell below 30x10(9)/l, while the lowest level in the SJM group was 75x10(9)/l. Based on multiple linear regression models, the type of valve implanted had a statistically significant influence on postoperative platelet counts on POD 1, POD 3, and POD 5 (p SOLO group.

    Sister chromatid cohesion is essential to maintain stable connections between homologues and sister chromatids during meiosis and to establish correct centromere orientation patterns on the meiosis I and II spindles. However, the meiotic cohesion apparatus in Drosophila melanogaster remains largely uncharacterized. We describe a novel protein, sisters on the loose (SOLO), which is essential for meiotic cohesion in Drosophila. In solo mutants, sister centromeres separate before prometaphase I, disrupting meiosis I centromere orientation and causing nondisjunction of both homologous and sister chromatids. Centromeric foci of the cohesin protein SMC1 are absent in solo mutants at all meiotic stages. SOLO and SMC1 colocalize to meiotic centromeres from early prophase I until anaphase II in wild-type males, but both proteins disappear prematurely at anaphase I in mutants for mei-S332, which encodes the Drosophila homologue of the cohesin protector protein shugoshin. The solo mutant phenotypes and the localization patterns of SOLO and SMC1 indicate that they function together to maintain sister chromatid cohesion in Drosophila meiosis.

    Full Text Available Machinery-based farming operations used for perennial fruit crops often damage soils, particularly if the soil is wet and prone to compaction. We hypothesized that perennial vegetation growing in the interrows of orange orchards can mitigate the soil physical degradation from machinery traffic. The objective of this study was to investigate the effects of different groundcover management systems on the soil physical quality indicators including the least limiting water range (LLWR. An experiment was started in 1993 in a Typic Paleudult to evaluate three groundcover management systems: Bahia grass (Paspalum notatum with mowing, perennial peanut (Arachis pintoi, and natural regrowth in which weeds were controlled by herbicide. The experimental design was randomized complete block with three replications. In May 2003, 216 undisturbed soil samples were collected at 0-0.15-m depths under and between wheel tracks in the orchard interrows. The soil bulk density, soil organic carbon content, resistance to penetration, soil water retention curve and soil resistance to penetration curve were determined in order to estimate the LLWR. The higher LLWR under wheel tracks in Bahia grass compared to perennial peanut or natural regrowth suggest that a better soil physical quality was achieved with Bahia grass.Operações motomecanizadas utilizadas no manejo das entrelinhas dos pomares de frutas com freqüência causam a degradação física do solo, especialmente quando realizadas com o solo úmido e suscetível à compactação.

    Full Text Available O paclobutrazol (PBZ é um regulador de crescimento utilizado em sistemas agrícolas com o propósito de controlar o crescimento vegetativo, estimulando a capacidade reprodutiva das plantas. Esse regulador de crescimento permanece ativo no solo por muito tempo, e sua meia-vida varia com o tipo de solo e as condições climáticas, podendo afetar severamente o desenvolvimento dos cultivos subseqüentes e, por lixiviação, contaminar os aqüíferos. Este trabalho teve como objetivo estudar os mecanismos envolvidos no transporte e na sorção do PBZ em colunas, utilizando amostras de um Argissolo Amarelo eutrófico e de um Vertissolo Háplico órtico, ambos da região do Vale do Rio São Francisco. Os ensaios de deslocamento miscível do traçador (solução de KBr e do paclobutrazol foram realizados considerando duas vazões (0,4 e 1,6 cm³ min-1 para ambos os solos. As variáveis hidrodispersivas foram obtidas pelo ajuste do modelo convecção dispersão (CDE às curvas de eluição experimentais do KBr, e as variáveis do modelo CDE-2 sítios de sorção, às curvas de eluição experimentais do PBZ por intermédio do programa CXTFIT 2.0. O paclobutrazol foi mais facilmente transportado no Vertissolo Háplico que no Argissolo Amarelo. A taxa de recuperação foi menor para a menor vazão para ambos os solos. A quantidade de PBZ não recuperada pode ser atribuída, sobretudo, à histerese no processo de sorção irreversível. O modelo CDE a dois sítios de sorção representa adequadamente os dados experimentais das curvas de eluição do paclobutrazol. Os resultados obtidos evidenciam que o paclobutrazol, utilizado em pomares com manga irrigada cujos solos são o Argissolo Amarelo e o Vertissolo Háplico, oferece risco real de contaminação das águas subterrâneas da região.Paclobutrazol (PBZ is a post-emergence plant growth regulator used in agricultural systems with the objective of vegetative control growth, thereby increasing the

    The purpose of this study was to evaluate the safety and performance of the Freedom Solo valve in aortic valve replacement by clinical and hemodynamic outcomes. Six hundred sixteen patients underwent aortic valve replacement in 18 European centers; mean age was 74.5 ± 5.9 years, 54.1% of the patients were male, and concomitant procedures were performed in 43.2% of the patients. The majority (69%) of the implanted sizes were 23 mm and 25 mm. At 1 year, overall survival was 94.0%, whereas freedom from valve-related death was 98.6%. There were 9 (1.5%) early (≤ 30 days) and 27 (4.4%) late (>30 days) deaths. Early and late valve-related mortality was 0.3% (n = 2) and 1.1% (n = 7), respectively. Freedom from explant was 97.6%; 10 valves were explanted for endocarditis and 4 for paravalvular leak. There were 10 (1.6%) early and 5 (0.8%) late strokes. Atrioventricular block requiring pacemaker implant occurred in 8 (1.3%) and 1 (0.2%) patients in the early and late postoperative period, respectively. Thrombocytopenia was seen in 27 cases (4.4%) in the early postoperative period. Preoperatively, 93.8% of patients were in New York Heart Association functional classes II through IV, whereas at 1 year 96.9% of patients were in New York Heart Association functional classes I and II. At 1-year follow-up, mean and peak pressure gradients were 7.2 and 14.6 mm Hg, respectively. Indexed left ventricular mass decreased by 12% from 138 g/m(2) at discharge to 122 g/m(2) at 1 year. At 1-year follow-up after Freedom Solo implantation, we found acceptable clinical results with low mortality and morbidity and good hemodynamic performance, confirming safety and effectiveness in this multicenter experience.

    Cerro Solo, located in Chubut, Argentina, is a sandstone type uranium-molybdenum deposit. Good recovery of both elements can be achieved by acid leaching of the ore but the presence of molybdenum in pregnant liquors is an inconvenient to uranium separation and purification. A two steps process is developed. A selective alkaline leaching of the ore with sodium hydroxide allows separating and recovering of molybdenum and after solid-liquid separation, the ore is acid leached to recover uranium. Several samples averaging 0,2% uranium and 0,1% molybdenum with variable U/Mo ratio have been used and in both steps, leaching and oxidant reagents concentration, temperature and residence time in a stirred tank leaching have been studied. In alkaline leaching molybdenum recoveries greater than 96% are achieved, with 1% uranium extraction. In acid leaching up to 93% of the uranium is extracted and Mo/U ratio in solvent extraction feed is between 0,013 and 0,025. (author)

  13. Mediamania? Contemporary German Poetry in the Age of New Information Technologies: Thomas Kling and Durs Grünbein

    Erk Grimm

    1997-01-01

    Full Text Available The essay examines the preoccupation with information technologies as a dominant theme of German poetry in the 1980s and 1990s. Outlining the historical shift from a critique of mass media to the ironic affirmation of hi-tech media, the investigation seeks an understanding of its driving forces. The analysis of Enzensberger's polemical essays on the culture industry shows the parallels and the difference in attitude between him and younger poets of the 1980s. A concise account of their publications illuminates the development of an aesthetically demanding poetry that kept aloof from the mass media. In their rejection of a common quotidian or sentimental tone, poets such as Thomas Kling and Durs Grunbein created new idioms and challenging forms while concentrating on hi-tech media as an epochal phenomenon. The sober reflection and technical terminology originate in a materialistic attitude, driven by the desire to regain the power of sophisticated aesthetic expression and to compensate for the loss of experience caused by the simulation of the past.The essay closes with a critical interpretation of the "mediamania" of the 1990s by giving heed to the fashionable remixing of poetic idioms that leaves the false impression of a new school of media poets.

    Full Text Available Com o objetivo de avaliar o potencial de resíduos de duas espécies vegetais em alterar a acidez do solo e a atividade do herbicida flumetsulam, foi conduzido um experimento em casa de vegetação no Departamento de Solos da Universidade Federal do Rio Grande do Sul, em novembro de 1998. Amostras da camada superficial (0-20cm de um cambissolo húmico distrófico foram colocadas em vasos, com capacidade de 1,0kg, onde se aplicou na superfície: 0, 5 e 10t ha-1 de resíduos de aveia-preta e de ervilhaca comum, com e sem aplicação do herbicida. Utilizou-se aveia-branca como cultura reagente. O delineamento experimental foi o inteiramente casualizado com três repetições. O resíduo da ervilhaca aumentou o pH do solo e ambos os resíduos diminuíram o alumínio trocável na camada de 0-3cm de profundidade, sendo o efeito da ervilhaca mais pronunciado. O decréscimo do alumínio trocável foi relacionado a dois mecanismos: complexação pela matéria orgânica e aumento do pH. Os resíduos vegetais aplicados sobre a superfície do solo aumentaram a eficiência do herbicida flumetsulam, especialmente quando o herbicida foi aplicado sobre os resíduos da leguminosa, que teve maior efeito na elevação do pH do solo.An experiment was conducted in the greenhouse of the Soils Department of the Federal University of Rio Grande do Sul, in November of 1998, to evaluate the potential of two crop residues to modify the acidity of the soil and the activity of the flumetsulam herbicide. The experimental units consisted of pots containing an Haplumbrept soil from the surface layer (0-20cm in with it was applyed 0, 5 and 10t ha-1 of black oat and of common vicia residues, with and without the herbicide application in the soil surface, and arranged in a complete randomized design, with three replications. White oat was used as test culture. Vicia residues increase soil pH and both residues decreased exchangeable Al in the 0-3cm layer, with the effect of vicia

    Full Text Available Muitas pesquisas conferem maior peso na alta declividade do terreno como fator decisivo no processo hidro-erosivo. Porém, foi avaliado que baixas declividades (~4º já são suficientes para se iniciar o escoamento superficial. A pesquisa teve como objetivo fazer uma caracterização físico-química de solo degradado, monitorar o seu potencial matricial e o processo de formação de escoamento em uma sub-bacia do rio Maranduba - Ubatuba/SP, em encosta com baixa declividade. O trabalho se baseou na instalação de parcelas de erosão em solo sem cobertura vegetal para analisar as perdas de solo e água, bem como as propriedades físicas e químicas do solo (Porosidade, textura, densidade, pH e matéria orgânica. As parcelas se localizam na parte intermediária de um morrote com encosta retilínea, esse sofreu alteração em sua morfologia original por meio de um corte de encosta (UTM: 0474211/7395934.  O solo do local é um Latossolo que apresenta o horizonte B exposto. Cerca de 6,9 t/ha de solo foram perdidos durante o monitoramento (01 agosto 2013-20 dezembro 2014 e mais de 5.354,7 m3 de água foram escoados superficialmente. Salienta-se a fragilidade dos ambientes degradados de baixa declividade frente às altas taxas de perdas de solo e água, que, no período de 17 meses de monitoramento e com chuvas dentro da normalidade para o município, totalizaram 63 dias com ocorrências de escoamento, em solos que tendem à saturação por períodos prolongados. Portanto, o transporte das partículas de solo superficialmente está atrelado à baixa drenagem do terreno e à perda da resistência do solo, corroborando em períodos longos de umidade antecedente, sendo este um dos fatores decisivos para se iniciar o escoamento superficial.

    Full Text Available O uso de fertilizantes que contêm baixos teores de enxofre (S, em solos com baixos teores de matéria orgânica, pode resultar em limitação desse nutriente para as culturas. O uso do S-elementar como fertilizante, isoladamente ou associado a fórmulas comerciais, pode reduzir os custos de adubação em solos deficientes de S. Os objetivos deste estudo foram: a verificar se, em dois solos tropicais, ocorre oxidação de S-elementar; b avaliar se o período de incubação de seis dias sugerido por Janzen & Bettany (1987a é adequado para estimar a oxidação do S-elementar e c medir o efeito da oxidação do S-elementar sobre o pH do solo. Para isso, foi realizado um experimento com amostras de um ARGISSOLO VERMELHO AMARELO eutrófico abruptíco e de um LATOSSOLO VERMELHO DISTRÓFICO típico. As amostras dos dois solos foram incubadas com seis doses de enxofre (0, 1,5, 3,0, 6,0 9,0 e 12g de So kg-1 de solo por períodos entre 0 e 70 dias. A incubação foi feita em estufa, a uma temperatura de 27o + 1o C. Ambos os solos tiveram capacidade para oxidar o S-elementar para S-sulfato, forma disponível à planta. No argissolo, o teor de S-sulfato resultante da oxidação do S-elementar foi 563mg dm-3 de solo, enquanto que, no latossolo, foi de 207mg dm-3 de solo, indicando capacidade diferenciada de ambos para oxidar o S-elementar. Em ambos os solos houve diminuição do pH, sendo mais acentuada para o argissolo. O período de incubação para avaliação da oxidação do S-elementar de seis dias sugerido por Janzen & Bettany (1987a parece ser insuficiente.

    Full Text Available Soil porosity, especially pore size distribution, is an important controlling factor for soil infiltration, hydraulic conductivity, and water retention. This study aimed to verify the effect of secondary-treated domestic wastewater (STW on the porosity of a sandy loam Oxisol in the city of Lins, state of São Paulo, Brazil. The two-year experiment was divided into three plots: soil cultivated with corn and sunflower and irrigated with STW, soil cultivated and irrigated with sodic groundwater, and non-irrigated and non-cultivated soil (control. At the end of the experiment, undisturbed core samples were sampled from 0 to 2.0 m (8 depths. The water retention curves were obtained by tension plates and Richard's pressure plate apparatus, and the pore size distribution inferred from the retention curves. It was found that irrigation with treated wastewater and treated groundwater led to a decrease in microporosity (V MI, defined as the pore class ranging from 0.2 to 50 μm diameter. On the other hand, a significant increase in cryptoporosity (V CRI (A porosidade do solo, principalmente a distribuição dos poros, é um fator importante que controla a infiltração de água, condutividade hidráulica e retenção da água no solo.
