Spatially continuous predictions of seabed hardness are important baseline environmental information for sustainable management of Australia’s marine jurisdiction. Seabed hardness is often inferred from multibeam backscatter data with unknown accuracy and can be inferred from underwater video footage at limited locations. In this study, we classified the seabed into four classes based on two new seabed hardness classification schemes (i.e., hard90 and hard70). We developed optimal predictive models to predict seabed hardness using random forest (RF) based on the point data of hardness classes and spatially continuous multibeam data. Five feature selection (FS) methods that are variable importance (VI), averaged variable importance (AVI), knowledge informed AVI (KIAVI), Boruta and regularized RF (RRF) were tested based on predictive accuracy. Effects of highly correlated, important and unimportant predictors on the accuracy of RF predictive models were examined. Finally, spatial predictions generated using the most accurate models were visually examined and analysed. This study confirmed that: 1) hard90 and hard70 are effective seabed hardness classification schemes; 2) seabed hardness of four classes can be predicted with a high degree of accuracy; 3) the typical approach used to pre-select predictive variables by excluding highly correlated variables needs to be re-examined; 4) the identification of the important and unimportant predictors provides useful guidelines for further improving predictive models; 5) FS methods select the most accurate predictive model(s) instead of the most parsimonious ones, and AVI and Boruta are recommended for future studies; and 6) RF is an effective modelling method with high predictive accuracy for multi-level categorical data and can be applied to ‘small p and large n’ problems in environmental sciences. Additionally, automated computational programs for AVI need to be developed to increase its computational efficiency and

Treatment with paramunity inducers Pind avi and Pind orf resulted in general in a smaller number of tumor takes as compared to BCG, Levamisol or untreated controls. Tumor growth curves were independent of treatment. Each experiment was replicated three times. A comparison of pooled results showed significant differences between Pind avi treatment and untreated controls for each level of tumor cells. When pooling levels of tumor cells and testing each replication separately there was a highly significant difference between Pind avi and controls and Pind orf and controls. BCG and Levamisole showed no significant difference to controls. Pind avi and Pind orf considerably raised the number of tumor cells needed to results in 50% takes. For BCG on the other hand less cells were needed. The TD 50 with Levamisole was somewhat higher than the TD 50 of controls. The formation of metastases was infrequent (0,65%), and only seen in lung tissue. (orig./MG) [de

At present, China's economic development faces energy challenge, and the appropriate solution of energy bottleneck is the key to healthy, rapid and sustainable development. China's gross amount of hydraulic resource ranks first in the world; however, because of low level of development, hydraulic resource has a broad development prospect. Now, China's hydropower development is in its peak period. By the end of 2004, the gross installed hydropower capacity of China broke through 100 million kW. From there, it has remained in the top slot worldwide. The vigorous development of hydropower is necessary because of the energy shortage and environmental pollution in China in order to attain sustainable development of China's economy. Abundant hydraulic resource, huge market demands, the strategy of western development and the favorable environment of economic development provide hydropower construction with unprecedented advantages and opportunities. Chins hydropower development aims at an installed hydropower capacity of up to 194 million kW by 2010, accounting for 23.1% of the gross installed power capacity and 35% of hydropower resource. Finally, we present the general condition of Three Gorges project as well as the new mode of hydropower development of Three Gorges Project Corporation, i.e., cascade development. (author)

This year the joint FAO/IAEA Division of Atomic Energy in Food and Agriculture celebrates its 10th anniversary. The aim of these two United Nations organizations is to ensure that the technical services of both FAO and IAEA are fully co-ordinated and their programmes are designed to assist developing Member States to apply isotopes and radiation techniques to the solution of food and agricultural problems. More precisely, the medium-term objectives of the Joint Division are to exploit the potential of nuclear techniques in research and development for increasing and stabilizing agricultural production, improving food quality, protecting agricultural products from spoilage and losses and minimizing pollution of food and the agricultural environment. This account of what radioisotopes can do for man in the agricultural field is therefore to a great extent a review of the activities of the Joint Division and a prediction of its future fields of emphasis, especially in the light of the present long-range and world-wide food crisis.

The gas turbine is the most widely used prime mover all over the world for either power generation or mechanical drive applications. The above fact is due to the recent great improvements that have been done especially in terms of efficiency, availability and reliability. The future for gas turbine technological development looks very promising. In fact, although tremendous growth has already taken place, there is still the potential for dramatic improvements in performance. Compared with the competitive prime movers (conventional steam power plants and reciprocating piston engines) the gas turbine technology is younger and still following a strong growth curve. The coming decades will witness the continued increasing in turbine inlet temperature, the development of new materials and refrigeration systems and the commercialization of inter cooled system and steam cooled turbines. With the very soon introduction of the G and H technology, expected single and combined cycle efficiencies for heavy duty machines are respectively 40% and 60%, while maintaining 'single digit' levels in pollutant emissions. In this report are given wide information on gas turbine present technology (Thermodynamics, features, design, performances, emission control, applications) and are discussed the main lines for the future developments. Finally are presented the research and technological development activities on gas turbine of Italian National Agency for new Technology Energy and the Environment Energy Department

Origin of the color of Cv. rhapsody in blue rose and some other so-called "blue" roses.

Science.gov (United States)

Gonnet, Jean-François

2003-08-13

Flowers of the rose cultivar Rhapsody in Blue display unusual colors, changing as they age, from a vivid red-purple to a lighter and duller purple, which are based on tonalities corresponding to hue angles between 340 and 320 degrees in the CIELAB scale. Unexpectedly, the chemical basis of these colors is among the simplest, featuring cyanin (cyanidin 3,5-di-O-glucoside), the most frequent anthocyanin in flowers, as the sole pigment and quercetin kaempferol glycosides as copigments at a relatively low copigment/pigment ratio (about 3/1), which usually produces magenta or red shades in roses. This color shift to bluer shades is coupled with the progressive accumulation of cyanin into vacuolar anthocyanic inclusions (AVIs), the occurrence of which increases as the petals grow older. In addition to the normal lambda(max) of cyanin at approximately 545 nm, the transmission spectra of live petals and of epidermal cells exhibit a second lambda(max) in the 620-625 nm range, the relative importance increasing with the presence of AVIs. In petals of fully opened flowers, the only pigmented structures in the vacuoles of epidermal cells are AVIs; their intense and massive absorption in the 520-640 nm area produces a much darker and bluer color than measured for the vacuolar solution present at the very first opening stage. Cyanin is probably "trapped" into AVIs at higher concentrations than would be possible in a vacuolar solution and in quinonoidal form, appearing purple-blue because of additional absorption in the 580-630 nm area. Quite similar pigmentation features were found in very ancient rose cultivars (cv. L'Evêque or Bleu Magenta), also displaying this type of so-called "blue" color.

Full Text Available Com o incremento exponencial da avicultura no Brasil, a disponibilidade de dejetos de aves e de cama de aviário tem aumentado de maneira semelhante. A proibição de uso desses produtos na ração animal tem feito com que eles sejam direcionados para a produção agrícola como fertilizantes. Ainda há na literatura carência de informação sobre lixiviação de bases no perfil do solo em conseqüência do efeito de ânions inorgânicos acompanhantes, como cloreto, nitrato e sulfato, e do efeito complexante de ácidos orgânicos de baixa massa molecular. O objetivo deste trabalho foi estudar o efeito da aplicação de cama de aviário na lixiviação de Ca, Mg, K e Na em solos e sua associação com ânions inorgânicos e ácidos orgânicos de baixa molecular. Amostras de dois Latossolos Vermelho-Amarelos, um de textura média e outro de textura argilosa, foram colocadas em colunas de PVC constituídas de cinco anéis, cada um com 10 cm de altura e 5 cm de diâmetro, ligados entre si com fita adesiva. O solo colocado no anel superior recebeu, homogeneamente, cinco tipos de camas de aviário: casca de café, casca de arroz, sabugo de milho, capim-napier e maravalha, totalizando 160 t ha-1 de material seco, comparado à testemunha (sem a cama de aviário. O experimento constituiu um fatorial 5 x 2, com cinco camas e dois solos, dispostos em blocos casualizados com três repetições.

Developing a "clinical presentation" curriculum at the University of Calgary.

Mandin, H; Harasym, P; Eagle, C; Watanabe, M

1995-03-01

Currently, medical curricula are structured according to disciplines, body systems, or clinical problems. Beginning in 1988, the faculty of the University of Calgary Faculty of Medicine (U of C) carefully evaluated the advantages and disadvantages of each of these models in seeking to revise their school's curriculum. However, all three models fell short of a curricular structure based on current knowledge and principles of adult learning, clinical problem solving, community demands, and curriculum management. By 1991, the U of C had formulated a strategic plan for a revised curriculum structure based on the way patients present to physicians, and implementation of this plan has begun. In creating the new curriculum, 120 clinical presentations (e.g., "loss of consciousness/syncope") were defined and each was assigned to an individual or small group of faculty for development based on faculty expertise and interest. Terminal objectives (i.e., "what to do") were defined for each presentation to describe the appropriate clinical behaviors of a graduating physician. Experts developed schemes that outlined how they differentiated one cause (i.e., disease category) from another. The underlying enabling objectives (i.e., knowledge, skills, and attitudes) for reaching the terminal objectives for each clinical presentation were assigned as departmental responsibilities. A new administrative structure evolved in which there is a partnership between a centralized multidisciplinary curriculum committee and the departments. This new competency-based, clinical presentation curriculum is expected to significantly enhance students' development of clinical problem-solving skills and affirms the premise that prudent, continuous updating is essential for improving the quality of medical education.

Self-presentation, a central element of young people's identity development, now extends from face-to-face contexts to social networking sites. Online self-presentation may change when youth transition to college, faced with the need to reclaim or redefine themselves in the new environment. Drawing on theories of self-presentation and self development, this study explores changes in youth's online self-presentation during their transition to a residential college. It also examines associations between online self-presentation and students' self-esteem and self-concept clarity. We surveyed 218 college freshmen (M age = 18.07; 64 % female, 79 % White) at the beginning and again at the end of their first semester. Freshmen's Facebook self-presentation became less restricted later in the semester. Broad, deep, positive, and authentic Facebook self-presentation was positively associated with perceived support from the audience, which contributed to higher self-esteem contemporaneously, though not longitudinally. Intentional Facebook self-presentation engaged students in self-reflection, which was related to lower self-concept clarity concurrently but higher self-esteem longitudinally. Findings clarified the paths from multifaceted online self-presentation to self development via interpersonal and intrapersonal processes during college transition.

Williams, Dustyn E; Surakanti, Shravani

2016-01-01

Oral case presentation is an essential skill in clinical practice that is decidedly varied and understudied in teaching curricula. We developed a curriculum to improve oral case presentation skills in medical students. As part of an internal medicine clerkship, students receive instruction in the elements of a good oral case presentation and then present a real-world case in front of a video camera. Each student self-evaluates his/her presentation and receives evaluations from his/her peers. We expect peer and self-evaluation to be meaningful tools for developing skills in oral presentation. We hope to not only improve the quality of oral case presentations by students but also to reduce the time burden on faculty.

Full Text Available ResumoA reciclagem energética de resíduos pode ser feita com o objetivo de geração de calor ou de gás combustível. Assim, este trabalho buscou viabilizar a utilização do resíduo chamado manipueira juntamente com os sólidos da cama de aviário evidenciando o potencial deste para a obtenção de biogás por meio de biodigestores. Foi desenvolvido para esse experimento um sistema exclusivo de biodigestão de biomassa formados por biodigestores batelada e gasômetros de cúpula móvel. Os resultados obtidos mostram que a cama de frango apresenta uma boa produção de biogás. A manipueira não foi obteve sucesso na mistura, pois fez com que a qualidade e quantidade do gás caíssem de acordo com o aumento na mistura.AbstractThe recycling of waste can be made for the purpose of generating heat or gas fuel. Thus, this project seeks to enable the use of cassava wastewater with poultry litter, emphasizing its potentiality for biogas production through anaerobic digesters. To accomplish this experiment a unique biomass digestion system formed of batch digesters and mobile gasometers was developed. The preliminary results showed that poultry litter offers a good production of biogas, but cassava wastewaters were not a good mixing option, because it affects adversely both the quantity and the quality of the biogas production.

Williams, Randi

This study was designed to explore elementary STEM professional development viewed from the presenters' and participants' perspectives. Numerous committees and educational organizations recommend investing in STEM professional development at the local, state, and national level. This investment must begin with research that inquires how STEM professional development is structured and what is needed for teacher and student success. Since there is a recent STEM education push in schools, elementary teachers need effective professional development in order to gain the necessary content, skills, confidence, and pedagogy required for those changing demands. This qualitative study embraced. Yin's case study methodology by observing short-duration STEM professional development for elementary teachers within a large metropolitan school system and an educational professional development agency. The study discussed the analysis and findings in the context of Bandura's sources of efficacy and Desimone's critical features of professional development. Data were gathered form professional development observations, presenter interviews, and participant interviews. The research questions for this study included: (a) based on Desimone's (2009) framework for professional development, what does content focused, active learning, coherence, duration, and collective participation look like in initial STEM professional development for elementary teachers? (b) are Bandura's (1997) four sources of self- efficacy: mastery experiences, vicarious experiences, social persuasion, and affective states evidenced within the short duration professional development? and (c) how do these two frameworks align between presenter and participant thoughts and actions? This study uncovered additional sources of efficacy are present in short-duration STEM professional development. These found sources include coherence, content, and active learning delivered in a definitive order. The findings of this study

To understand the present status and characteristics of Dendrobium officinale industry and to provide a rationale for the sustainable industrial development. Based on references and an on-site investigation of main Dendrobium officinale-producing enterprises and market, to analyze main existing problems and to propose suggestions for sustainable development. More than 10 provinces and regions are involved in the production around the center of Zhejiang and Yunnan provinces. These two provinces are different from each other in development pattern. Yunnan adopts a mode of companies minus farmer households but Zhejiang mainly employs a mode that a leading company establishes a production base with production, processing and marketing combined together. Zhejiang mode is characterized by high tech, high investment, high risk and high return. Existence of non-genuine species, stagnancy in development and application of varieties and techniques for quality control and a narrow channel for marketing are the key problems limiting sustainable development of the industry. The key to sustainable development of the industry is to establish a technological alliance to speed up development of common techniques and application of integrated innovations, to strengthen self-discipline and monitoring of production, and to expand sales market.

2013-01-01

Abstract Disorders of sex development (DSD) present in different forms but, in most cases, with visible anomalies of the external genitalia. The diagnosis of DSD can have a vast impact on an individual; in addition to concerns about fertility and a higher risk of neoplasia, it may have severe...... psychosocial impact on the patient. This report presents two apparently healthy cases referred for operation because of unilateral undescended testis. In these two patients, uterine remnants were found during the operation, and underlying DSD conditions were unexpectedly diagnosed. One patient had a 45,X/46,XY...... mosaic karyotype, while the second patient had persistent müllerian duct syndrome, probably due to an anti-müllerian hormone receptor defect. Both conditions are extremely rare, but the findings reinforce that DSD should be considered in patients with cryptorchidism, especially if other clinical signs...

Klebsiella pneumoniae Carbapenemase-2 (KPC-2), Substitutions at Ambler Position Asp179, and Resistance to Ceftazidime-Avibactam: Unique Antibiotic-Resistant Phenotypes Emerge from β-Lactamase Protein Engineering.

The emergence of Klebsiella pneumoniae carbapenemases (KPCs), β-lactamases that inactivate "last-line" antibiotics such as imipenem, represents a major challenge to contemporary antibiotic therapies. The combination of ceftazidime (CAZ) and avibactam (AVI), a potent β-lactamase inhibitor, represents an attempt to overcome this formidable threat and to restore the efficacy of the antibiotic against Gram-negative bacteria bearing KPCs. CAZ-AVI-resistant clinical strains expressing KPC variants with substitutions in the Ω-loop are emerging. We engineered 19 KPC-2 variants bearing targeted mutations at amino acid residue Ambler position 179 in Escherichia coli and identified a unique antibiotic resistance phenotype. We focus particularly on the CAZ-AVI resistance of the clinically relevant Asp179Asn variant. Although this variant demonstrated less hydrolytic activity, we demonstrated that there was a prolonged period during which an acyl-enzyme intermediate was present. Using mass spectrometry and transient kinetic analysis, we demonstrated that Asp179Asn "traps" β-lactams, preferentially binding β-lactams longer than AVI owing to a decreased rate of deacylation. Molecular dynamics simulations predict that (i) the Asp179Asn variant confers more flexibility to the Ω-loop and expands the active site significantly; (ii) the catalytic nucleophile, S70, is shifted more than 1.5 Å and rotated more than 90°, altering the hydrogen bond networks; and (iii) E166 is displaced by 2 Å when complexed with ceftazidime. These analyses explain the increased hydrolytic profile of KPC-2 and suggest that the Asp179Asn substitution results in an alternative complex mechanism leading to CAZ-AVI resistance. The future design of novel β-lactams and β-lactamase inhibitors must consider the mechanistic basis of resistance of this and other threatening carbapenemases. IMPORTANCE Antibiotic resistance is emerging at unprecedented rates and threatens to reach crisis levels. One key

TAS2R38 and CA6 genetic polymorphisms, frequency of bitter food intake, and blood biomarkers among elderly woman.

Science.gov (United States)

Mikołajczyk-Stecyna, Joanna; Malinowska, Anna M; Chmurzynska, Agata

2017-09-01

Taste sensitivity is one of the most important biological determinants of food choice. Three SNPs of the TAS2R38 gene (rs713598, rs1726866, and rs10246939) give rise to two common haplotypes: PAV and AVI. These haplotypes, as well as an SNP within the CA6 gene (rs2274333) that encodes carbonic anhydrase VI (CA6), correlate with bitterness perception. The extent of consumption of bitter food may influence some health outcomes. The aim of this study is thus to investigate the impact of the TAS2R38 and CA6 genetic polymorphisms on the choice of bitter food, BMI, blood lipoprotein, and glucose concentrations as well as systemic inflammation in elderly women. The associations between the TAS2R38 diplotype, CA6 genotype, and the intake of bitter-tasting foods were studied in a group of 118 Polish women over 60 years of age. The intake of Brassica vegetables, grapefruit, and coffee was assessed using a food frequency questionnaire. Biochemical parameters were measured using the spectrophotometric method. Genotyping was performed using the high resolution melting method. We found a correlation between lipid profile, glucose and CRP levels, and frequency of bitter food intake. The AVI/AVI subjects drank coffee more frequently than did the PAV/PAV homozygotes, as did the A carriers of CA6 in comparison with the GG homozygotes. We also observed that simultaneous carriers of the PAV haplotype and A allele of TAS2R38 and CA6, respectively, choose white cabbage more frequent and had lower plasma levels of CRP and glucose than did AVI/AVI and GG homozygotes. In elderly women, the TAS2R38 and CA6 polymorphisms may affect the frequency of consumption of coffee and white cabbage, but not of other bitter-tasting foods. Copyright © 2017 Elsevier Ltd.

Monitoring osseointegration and developing intelligent systems (Conference Presentation)

Science.gov (United States)

Salvino, Liming W.

2017-05-01

Effective monitoring of structural and biological systems is an extremely important research area that enables technology development for future intelligent devices, platforms, and systems. This presentation provides an overview of research efforts funded by the Office of Naval Research (ONR) to establish structural health monitoring (SHM) methodologies in the human domain. Basic science efforts are needed to utilize SHM sensing, data analysis, modeling, and algorithms to obtain the relevant physiological and biological information for human-specific health and performance conditions. This overview of current research efforts is based on the Monitoring Osseointegrated Prosthesis (MOIP) program. MOIP develops implantable and intelligent prosthetics that are directly anchored to the bone of residual limbs. Through real-time monitoring, sensing, and responding to osseointegration of bones and implants as well as interface conditions and environment, our research program aims to obtain individualized actionable information for implant failure identification, load estimation, infection mitigation and treatment, as well as healing assessment. Looking ahead to achieve ultimate goals of SHM, we seek to expand our research areas to cover monitoring human, biological and engineered systems, as well as human-machine interfaces. Examples of such include 1) brainwave monitoring and neurological control, 2) detecting and evaluating brain injuries, 3) monitoring and maximizing human-technological object teaming, and 4) closed-loop setups in which actions can be triggered automatically based on sensors, actuators, and data signatures. Finally, some ongoing and future collaborations across different disciplines for the development of knowledge automation and intelligent systems will be discussed.

Fond, G; Franc, N; Purper-Ouakil, D

2012-02-01

The aim of this article is to provide an overview of existing studies on gay and lesbian parenthood and child development. Although 200,000 to 300,000 children could be concerned in 2010 in France, there is a lack of research on this issue in our country. Research among children raised by homosexual parents involves methodological issues, such as defining homosexual families, sampling cases and controls, and choosing structured or semi-structured evaluations. The fact that homosexual marriage, adoption and insemination are not presently legal in France could explain that only one study has been conducted in France in 2000 among 58 children raided by homosexual parents. This study concluded that these children did not show an increased rate of behavior or anxiety disorders. Concerns about lesbian parenting have focused on the absence of a father, the homosexual orientation of the mother, and their negative consequences on the development of the children. Research on parenting and child rearing has repeatedly compared lesbian and heterosexual families, and in the last 30 years a growing body of studies on lesbian parents and the development of their children has been published. Studies about child development, sexual orientation, gender identity, gender role behavior, emotional/behavioral development, social relationships and cognitive functioning showed no difference between children of lesbian mothers and those of heterosexual parents. Likewise, parental functioning, the mothers' psychological health and maternal skills were not significantly different among lesbian mothers than among heterosexual mothers. In studies concerning gay fathers, findings generally indicate no differences in sexual orientation, socialization, or psychological outcomes in children of gay fathers compared to children of heterosexual fathers. However, the first study on the adult attachment style dimensions of adult women who had gay or bisexual fathers suggested that they were

2004-01-01

A present Japanese national project for SMES development focuses on the development of cost reduction technologies for a small-scale SMES for power system control. Optimal SMES system concepts were developed for power system stabilization and for load fluctuation compensation or frequency regulation. Performance of the designed superconductors was analyzed through fabrication and tests of short sample superconductors. Then, two kinds of model coil systems were manufactured and tested for evaluation of the design concepts and cost reduction technology developments. A multi-pole solenoid coil set as a model coil system for load fluctuation compensation SMES was successfully tested, for example, in 10 000-pulse iterative charge-discharge operations. In addition, application of high-T C superconductors to SMES has been studied for further cost reduction, more reliable operation, etc

Nakamura, K.; Abe, T.; Obara, K.; Murakami, Y.

1986-01-01

In the JT-60 at JAERI, TiC-coated molybdenum and TiC-coated Inconel tiles are currently used as plasma interactive components. They have already been subjected to initial ohmic heating experiments and exhibited good adhesion characteristics under high heat flux conditions. The present article reviews a JAERI's coating development program for JT-60 experiments currently under way and for the next-step experiments. The program includes development and performance tests of the TiC-coated tiles, development of an in-situ coating technique for the repair of damaged surface of the tiles, and research on carbonization. Stress is laid on thermal shock and thermal fatigue tests of these coatings. In the thermal tests, adhesion between low-Z coatings and bulk materials have been investigated under high heat irradiation. TiC and TiN are used as coating material while Mo and Inconel 625 are employed as bulk material. Results are shown in this report concerning calculated temperature elavation of TiC/TiN/Mo due to hydrogen beam irradiation. As regards the irradiation time required for the melting of the substrate, experimental results mostly agree with calculations. Almost all coatings investigated are not exfoliated from the substrate until the melting of the substrate. (Nogami, K.)

In the present paper, the current situation of the Cuban nuclear medicine, after its introduction in the country in the 40s of the 20 th century and its expansion since 1962 and, particularly, from the installation of the first gamma camera in 1980, is analyzed. Nowadays, there is a total 14 Nuclear Medicine Departments or Services in our country within the National Oncology Networks and national Health System (SNS), which provide medical attention to the population depending on the nuclear equipment available A Program for the medical and technical personnel's training is proposed, as well as for gradual development of nuclear medicine department's (including the installation of gamma cameras, divided into two stages: 2003-2004 and 2005-2006). The prospective results of the proposed program are analyzed, as well as the impact on the populations health

Engaging the audience: developing presentation skills in science students.

Science.gov (United States)

Stuart, Ann E

2013-01-01

This article describes a graduate class in presentation skills ("PClass") as a model for how a class with similar objectives, expectations and culture might be mounted for undergraduates. The required class is given for students in neuroscience and physiology programs at the University of North Carolina at Chapel Hill; I describe the class in the years I led it, from 2003-2012. The class structure centered on peer rehearsal, critiquing of PowerPoint, and chalk talks by the students; video-recording of student talks for later review by the student with the instructor; and presentation of polished talks in a formal setting. A different faculty visitor to the class each week gave the students a variety of perspectives. The students also gained insight into their own evolving skills by discussing the strengths and weaknesses of seminars given by visitors to the campus. A unique feature of the class was collaboration with a professional actor from the University's Department of Dramatic Arts, who helped the students develop techniques for keeping the attention of an audience, for speaking with confidence, and for controlling nervousness. The undergraduate campus would be expected to lend itself to this sort of interdisciplinary faculty cooperation. In addition, students worked on becoming adept at designing and presenting posters, introducing speakers graciously and taking charge of the speaker's question session, and speaking to a lay audience.

Directory of Open Access Journals (Sweden)

Phung Khanh Lam

Full Text Available To identify risk factors and develop a prediction model for the development of profound and recurrent shock amongst children presenting with dengue shock syndrome (DSS.We analyzed data from a prospective cohort of children with DSS recruited at the Paediatric Intensive Care Unit of the Hospital for Tropical Disease in Ho Chi Minh City, Vietnam. The primary endpoint was "profound DSS", defined as ≥2 recurrent shock episodes (for subjects presenting in compensated shock, or ≥1 recurrent shock episodes (for subjects presenting initially with decompensated/hypotensive shock, and/or requirement for inotropic support. Recurrent shock was evaluated as a secondary endpoint. Risk factors were pre-defined clinical and laboratory variables collected at the time of presentation with shock. Prognostic model development was based on logistic regression and compared to several alternative approaches.The analysis population included 1207 children of whom 222 (18% progressed to "profound DSS" and 433 (36% had recurrent shock. Independent risk factors for both endpoints included younger age, earlier presentation, higher pulse rate, higher temperature, higher haematocrit and, for females, worse hemodynamic status at presentation. The final prognostic model for "profound DSS" showed acceptable discrimination (AUC=0.69 for internal validation and calibration and is presented as a simple score-chart.Several risk factors for development of profound or recurrent shock among children presenting with DSS were identified. The score-chart derived from the prognostic models should improve triage and management of children presenting with DSS in dengue-endemic areas.

[Ecology and health in Chile: present and future development].

Oyarzún, M

1997-09-01

In response to the progressive environmental deterioration, the Ecological Society of America has made a proposal, called "Sustainable Biosphere Initiative", to do research, teaching and decision making processes on biodiversity, global change and the effects of human activities on environment. The goal of appropriate environmental protection and welfare for mankind includes health and quality of life. Presently, Chile faces a number of environmental problems such as pollution, excessive urban growth, loss of agricultural areas, disposal of solid waste and species extinction. The lack of education and information in Chile, on these problems, is worrisome. The role of universities to overcome this deficit should be crucial in the future sustainable development of Chile.

To improve the detection and quality of care of patients who attend the emergency department (ED) with confirmed or suspected domestic abuse (DA). A quality improvement report on the design, implementation and evaluation of a specialised service and structured training programme to detect and manage DA presentations within an emergency medicine department. The study was set in the ED at the Northern General Hospital, Sheffield, UK. Key measures for improvement included introducing a service within the ED to help staff manage DA and coordinate responses; improve staff confidence in detecting DA; develop a structured and consistent process by which to manage DA presentations. An Independent Domestic Violence Advocate service was introduced into the department in July 2011 through a multiagency agreement. A structured training and education programme was delivered to ED staff. A 'communications form' was developed for DA risk assessment and case management. The process was reviewed quarterly. One hundred and seventy-two referrals were made to the service (121 distinct clients) over a 12-month period. Staff reported greater confidence in detecting DA, and community partners highlighted the role the service had in improving DA detection and care quality within the city. Strong leadership and prioritising the issue within the department has facilitated the development of the process and contributed substantially to its success. Support from community partners has been invaluable in tailoring the service and education programme to the needs of staff and patients within the department.

Development and Presentation of the Drigg Post-Closure Safety Case

International Nuclear Information System (INIS)

Kelly, Eugene; Watts, Len; Grimwood, Paul

2001-01-01

Drigg is an operational facility for the near-surface disposal of solid low level radioactive waste (LLW). The disposal facility is located in Cumbria, north-west England, near the Sellafield nuclear site, and is owned and operated by British Nuclear Fuels plc (BNFL). Disposals at Drigg are carried out under the terms of an authorisation granted by the UK Environment Agency. Periodically the Drigg authorisation is subject to formal regulatory review. The current regulatory guidance, 'Disposal Facilities on Land for Low and Intermediate Level Radioactive Wastes: Guidance on Requirements for Authorisation' (the GRA) was published in 1997 and contains guidance on the principles and requirements against which the Environment Agency will consider applications for disposal authorisation. BNFL has undertaken to produce an updated Drigg postclosure safety case (PCSC) in September 2002 to support the next authorisation review. In preparation for this, BNFL published a 'Status Report on the Development of the 2002 Drigg PCSC' in March 2000. This paper discusses the main components of the Drigg PCSC and how they relate to each other. Central to the safety case will be a systematic, post-closure radiological safety assessment (PCRSA). However the main focus of this paper is on the other main components of the PCSC which are presented in conjunction with the PCRSA to make a complete and integrated safety case. In addition other confidence building activities which are key to developing and presenting the safety case are discussed, in particular communications with the stakeholders

The last year was the 50th year from the discovery of the nuclear fission of uranium in 1939. The utilization of atomic energy made the unfortunate start as atomic bombs, but after the 'Atoms for Peace' declaration of President Eisenhauer, it has become to contribute to the development of mankind as nuclear power generation and radiation utilization. In Japan, the Atomic Energy Act was instituted in 1955, and the utilization of atomic energy has been eagerly promoted. As to nuclear power generation, as of the end of June, 1989, 423 power plants were in operation in the world, which generated 333 million kW, equivalent to 17 % of the total generated electric power. The nuclear power plants under construction and at planning stage were 199 with 190 million kW capacity, in this way, the development is advanced actively. At present in Japan, 38 nuclear power plants are in operation, generating 29.46 million kW, which has reached 30 % of the total generated electric power. The social environment surrounding atomic energy and the basic way of thinking on atomic energy development are discussed. The demand and supply of electric power in 21st century and atomic energy, and the policy of electric power companies to cope with it are explained. (K.I.)

Science.gov (United States)

Gu, Kaiyun; Chang, Yu; Gao, Bin; Wan, Feng; Loisance, Daniel; Zeng, Yi

2014-08-01

The growing number of heart failure patients and the scarcity of organ donors account for the huge need for the development of mechanical circulatory systems, including ventricular assist devices (VADs) and artificial hearts, in China. Several research programmes on blood pumps have been under way for the last three decades. However, unlike in other countries, the development of VADs has been extremely slow, and no system is currently approved and available for clinical application. There are many reasons for this situation. This article provides an overview of the present development of experimental and clinical research on VADs in China. In addition, the challenges for the clinical development of mechanical circulatory support in China are discussed. © The Author 2014.

Evolution and development of the concept of partitioning of high-level liquid wastes (HLLW) in nuclear fuel reprocessing are reviewed historically from the early phase of separating useful radioisotopes from HLLW to the recent phase of eliminating hazardous nuclides such as transuranium elements for safe waste disposal. Since the criteria in determining the nuclides for elimination and the respective decontamination factors are important in the strategy of partitioning, current views on the criteria are summarized. As elimination of the transuranium is most significant in the partitioning, various methods available of separating them from fission products are evaluated. (auth.)

Nuclear power in the world. Its present status and development trends

International Nuclear Information System (INIS)

Bennett, L.

1994-01-01

A summary of the most important data about the nuclear power reactors in operation and under construction as of the end of 1993 is given: their capacity, share of world capacity, growth of nuclear electricity generation since 1970 and its distribution by country. Nuclear prospects in the medium (2015) and long term (2025) are connected with a broad range of factors: development of advanced reactors ensuring high level of safety, implementation of high level waste repositories, enhancing the public acceptance of nuclear power. The issue of the cost of electricity generation is also discussed. Nuclear capacity projections to 2015 by region are given with 'low' and 'high' estimates. The low case reflects the continuation of the present trend of stagnation in nuclear power development due to public opposition and low economic growth in OECD countries, uncertainties in Eastern Europe and lack of finding in developing countries. The high case reflects a moderate revival of nuclear power development in the light of a more comprehensive assessment of the macro-economic and environmental aspects of the different options available for electricity generation. 7 figs., 5 tabs.

Transapical (TA) aortic valve implantation (AVI) has evolved as an alternative procedure for high-risk patients. We evaluated the second-generation SAPIEN XT™ prosthesis in a prospective multicentre clinical trial. A total of 150 patients (age: 81.6 ± 5.8 years; 40.7% female) were included. Prosthetic valves (diameter: 23 mm (n = 36), 26 mm (n = 57) and 29 mm (n = 57)) were implanted. The ASCENDRA-II™ modified delivery system was used in the smaller sizes. Mean logistic EuroSCORE was 24.3 ± 7.0%, and mean STS score 7.5 ± 4.4%. All patients gave written informed consent. Off-pump AVI was performed using femoral arterial and venous access wires as a safety net. All but two patients received TA-AVI, as planned. The 29-mm valve showed similar function as the values of two other diameters did. Three patients (2%) required temporary cardiopulmonary bypass support. Postoperative complications included renal failure requiring long-term dialysis in four, bleeding requiring rethoracotomy in four, respiratory complication requiring reintubation in eight and sepsis in four patients, respectively. Thirty-day mortality was 13 (8.7%) for the total cohort and 2/57 (3.5%) for patients receiving the 29-mm valve, respectively. Echocardiography at discharge showed none or trivial aortic incompetence (AI) in 71% and mild-AI in 22% of the patients. Post-implantation AI was predominantly paravalvular and ≥ 2+ in 7% of patients. One patient required reoperation for AI within 30 days. The PREVAIL TA multicentre trial demonstrates good functionality and good outcomes for TA-AVI, using the SAPIEN XT™ prosthesis and its second-generation ASCENDRA-II™ delivery system, as well successful introduction of the 29-mm SAPIEN XT™ valve for the benefit of high-risk elderly patients.

Coordinating Permit Offices and the Development of Utility-Scale Geothermal Energy (Presentation)

2013-10-01

Permitting is a major component of the geothermal development process. Better coordination across government agencies could reduce uncertainty of the process and the actual time of permitting. This presentation highlights various forms of coordinating permit offices at the state and federal level in the western United States, discusses inefficiencies and mitigation techniques for permitting natural resource projects, analyzes whether various approaches are easily adaptable to utility-scale geothermal development, and addresses advantages and challenges for coordinating permit offices. Key successful strategies identified include: 1. Flexibility in implementing the approach (i.e. less statutory requirements for the approach); 2. Less dependence on a final environmental review for information sharing and permit coordination; 3. State and federal partnerships developed through memorandum of understanding to define roles and share data and/or developer information. A few of the most helpful techniques include: 1. A central point of contact for the developer to ask questions surrounding the project; 2. Pre-application meetings to assist the developer in identifying all of the permits, regulatory approvals, and associated information or data required; 3. A permit schedule or timeline to set expectations for the developer and agencies; 4. Consolidating the public notice, comment, and hearing period into fewer hearings held concurrently.

1990-08-01

Present detectors for digital radiography are of two classes: real time detectors and storage (non real time) types. Present real time detectors consist of image intensifier tubes with an internal cesium iodide layer x-ray converter. Non real time detectors involve linear sweep arrays or storage detectors such as film. Future detectors discussed here can be of both types utilizing new technologies such as hydrogenated amorphous silicon photodiode arrays coupled to thin film transistor arrays. 17 refs., 10 figs

Full Text Available Telepathology which is the diagnostic work of a pathologist at a distance has been developed to routine application within the last ten years. It can be classified in relation to application, technical solutions, or performance conditions. Diagnostic pathology performance distinguishes primary diagnosis (for example, frozen section statement from secondary diagnosis (for example, expert consultation and quality assurance (diagnostic accuracy, continuous education and training. Applications comprise (a frozen section service; (b expert consultations; (c remote control measurements; and (d education and training. The technical solutions distinguish active (remote control, live imaging systems from passive (conventional microscope handling, static imaging, and the performance systems with interactive (on‐line, live imaging use from those with passive (off‐line, static imaging practice. Intra‐operative frozen section service is mainly performed with remote control systems; whereas expert consultations and education/training are commonly based upon Internet connections with static imaging in an off‐line mode. The image quality, transfer rates, and screen resolution of active and passive telepathology systems are sufficient for an additional or primary judgment of histological slides and cytological smears. From the technical point of view, remote control telepathology requires a fast transfer and at least near on‐line judgement of images, i.e., image acquisition, transfer and presentation can be considered one performance function. Thus, image size, line transfer rate and screen resolution define the practicability of the system. In expert consultation, the pixel resolution of images and natural color presentation are the main factors for diagnostic support, whereas the line transfer rate is of minor importance. These conditions define the technical compartments, especially size and resolution of camera and screen. The performance of

The roles of taste and astringent properties, food choice motives and health concerns in liking of bilberry and crowberry samples were studied using a sensory panel prescreened for the hTAS2R38 taste receptor genotype. The subjects rated the intensity of sourness, bitterness and two astringent properties (soft, velvety and rough, puckering) of all berry samples. They also scored the liking of juice fractions and completed a food choice motive and health concern questionnaire. Regression models were used to combine different data sets and to predict liking of the extracts. Sourness contributed positively to the liking of berry fractions, and bitterness and rough astringency were negative factors. The hTAS2R38 genotype affected the liking of polyphenol-rich extracts, which were significantly bitter and astringent. Based on the genotype grouping of subjects, PAV homozygotes gave lower ratings to the attributes than AVI homozygotes. In contrast, PAV homozygotes were predicted to dislike the extracts notably more than AVI homozygotes. Health concern and food choice motives related to health and weight control had significant roles in individual liking of juice fractions. Our results indicate that mood was more important to the PAV homozygotes than to the AVI homozygotes. Copyright © 2012 Elsevier Ltd. All rights reserved.

Present status of nuclear energy development and utilization in Japan 1994

International Nuclear Information System (INIS)

1994-03-01

Today, world energy demands continue to increase, and over the middle and long-term, access to petroleum supplies may become difficult. At the same time, such serious environmental problems as global warming and acid rain, which are caused by the burning of fossil fuels, have drawn great public attention, and the international community has urged that solutions to them should be found. Because nuclear power offers an economically efficient, stable supply of energy whose production has little adverse effect on the environment, the world has recognized the necessity of continuing to develop and use it. The changing international political situation, however, has complicated nuclear energy matters. In Japan, particularly the collapse of the former Soviet Union and North Korea's announcement of its intention to withdraw from the Nuclear Weapons Non-Proliferation Treaty have been cause for concern. Under these circumstances, it has become increasingly important for Japan to secure stable sources of energy, since Japan is dependent on imports for its energy supply. To that end, Japan has steadily promoted the development and utilization of nuclear energy. In fiscal 1992, nuclear power accounted for 28.2 % of the total power generated by Japanese electric utilities. Japan has also worked steadily to develop a nuclear fuel cycle, which is important to the long-term stability of the energy supply. This publication describes the present status of nuclear energy development and utilization in Japan. (J.P.N.)

Modern textile industry seeks to produce textiles as little defective as possible since the presence of defects can decrease the final price of products from 45% to 65%. Automated visual inspection (AVI) systems, based on image analysis, have become an important alternative for replacing traditional inspections methods that involve human tasks. An AVI system gives the advantage of repeatability when implemented within defined constrains, offering more objective and reliable results for particular tasks than human inspection. Costs of automated inspection systems development can be reduced using modular solutions with embedded systems, in which an important advantage is the low energy consumption. Among the possibilities for developing embedded systems, the ARM processor has been explored for acquisition, monitoring and simple signal processing tasks. In a recent approach we have explored the use of the ARM processor for defects detection by implementing the wavelet transform. However, the computation speed of the preprocessing was not yet sufficient for real time applications. In this approach we significantly improve the preprocessing speed of the algorithm, by optimizing matrix operations, such that it is adequate for a real time application. The system was tested for defect detection using different defect types. The paper is focused in giving a detailed description of the basis of the algorithm implementation, such that other algorithms may use of the ARM operations for fast implementations.

Development of an efficient signal amplification strategy for label-free enzyme immunoassay using two site-specific biotinylated recombinant proteins

Highlights: • An efficient signal amplification strategy for label-free EIA is proposed. • Divalent biotinylated AP and monovalent biotinylated ZZ were prepared via Avitag–BirA system. • The above site-specific biotinylated fusion proteins form complex via SA–biotin interaction. • The mechanism relies on the ZZ–Avi-B/SA/AP–(Avi-B) 2 complex. • The analytical signals are enhanced (32-fold) by the proposed strategy. - Abstract: Constructing a recombinant protein between a reporter enzyme and a detector protein to produce a homogeneous immunological reagent is advantageous over random chemical conjugation. However, the approach hardly recombines multiple enzymes in a difunctional fusion protein, which results in insufficient amplification of the enzymatic signal, thereby limiting its application in further enhancement of analytical signal. In this study, two site-specific biotinylated recombinant proteins, namely, divalent biotinylated alkaline phosphatase (AP) and monovalent biotinylated ZZ domain, were produced by employing the Avitag–BirA system. Through the high streptavidin (SA)–biotin interaction, the divalent biotinylated APs were clustered in the SA–biotin complex and then incorporated with the biotinylated ZZ. This incorporation results in the formation of a functional macromolecule that involves numerous APs, thereby enhancing the enzymatic signal, and in the production of several ZZ molecules for the interaction with immunoglobulin G (IgG) antibody. The advantage of this signal amplification strategy is demonstrated through ELISA, in which the analytical signal was substantially enhanced, with a 32-fold increase in the detection sensitivity compared with the ZZ–AP fusion protein approach. The proposed immunoassay without chemical modification can be an alternative strategy to enhance the analytical signals in various applications involving immunosensors and diagnostic chips, given that the label-free IgG antibody is suitable for

Molecular markers, due to their stability, cost-effectiveness and ease of use provide an immensely popular tool for a variety of applications including genome mapping, gene tagging, genetic diversity diversity, phylogenetic analysis and forensic investigations. In the last three decades, a number of molecular marker techniques have been developed and exploited worldwide in different systems. However, only a handful of these techniques, namely RFLPs, RAPDs, AFLPs, ISSRs, SSRs and SNPs have received global acceptance. A recent revolution in DNA sequencing techniques has taken the discovery and application of molecular markers to high-throughput and ultrahigh-throughput levels. Although, the choice of marker will obviously depend on the targeted use, microsatellites, SNPs and genotyping by sequencing (GBS) largely fulfill most of the user requirements. Further, modern transcriptomic and functional markers will lead the ventures onto high-density genetic map construction, identification of QTLs, breeding and conservation strategies in times to come in combination with other high throughput techniques. This review presents an overview of different marker technologies and their variants with a comparative account of their characteristic features and applications.

Engineering tendon and ligament tissues: present developments towards successful clinical products.

Musculoskeletal diseases are one of the leading causes of disability worldwide. Among them, tendon and ligament injuries represent an important aspect to consider in both athletes and active working people. Tendon and ligament damage is an important cause of joint instability, and progresses into early onset of osteoarthritis, pain, disability and eventually the need for joint replacement surgery. The social and economical burden associated with these medical conditions presents a compelling argument for greater understanding and expanding research on this issue. The particular physiology of tendons and ligaments (avascular, hypocellular and overall structural mechanical features) makes it difficult for currently available treatments to reach a complete and long-term functional repair of the damaged tissue, especially when complete tear occurs. Despite the effort, the treatment modalities for tendon and ligament are suboptimal, which have led to the development of alternative therapies, such as the delivery of growth factors, development of engineered scaffolds or the application of stem cells, which have been approached in this review.

2017-01-01

Pharmaceutical medical writing has grown significantly in India in the last couple of decades. It includes preparing regulatory, safety, and publication documents as well as educational and communication material related to health and health-care products. Medical writing requires medical understanding, knowledge of drug development and the regulatory and safety domains, understanding of research methodologies, and awareness of relevant regulations and guidelines. It also requires the ability to analyze, interpret, and present biomedical scientific data in the required format and good writing skills. Medical writing is the fourth most commonly outsourced clinical development activity, and its global demand has steadily increased due to rising cost pressures on the pharmaceutical industry. India has the unique advantages of a large workforce of science graduates and medical professionals trained in English and lower costs, which make it a suitable destination for outsourcing medical writing services. However, the current share of India in global medical writing business is very small. This industry in India faces some real challenges, such as the lack of depth and breadth in domain expertise, inadequate technical writing skills, high attrition rates, and paucity of standardized training programs as well as quality assessment tools. Focusing our time, attention, and resources to address these challenges will help the Indian medical writing industry gain its rightful share in the global medical writing business. PMID:28194338

Full Text Available The habenular neural circuit is attracting increasing attention from researchers in fields as diverse as neuroscience, medicine, behavior, development and evolution. Recent studies have revealed that this part of the limbic system in the dorsal diencephalon is involved in reward, addiction and other behaviors and its impairment is associated with various neurological conditions and diseases. Since the initial description of the Dorsal Diencephalic Conduction system (DDC with the habenulae in its center at the end of the 19th century, increasingly sophisticated techniques have resolved much of its anatomy and have shown that these pathways relay information from different parts of the forebrain to the tegmentum, midbrain and hindbrain. The first part of this review gives a brief historical overview on how the improving experimental approaches have allowed the stepwise uncovering of much of the architecture of the habenula circuit as we know it today. Our brain distributes tasks differentially between left and right and it has become a paradigm that this functional lateralization is a universal feature of vertebrates. Moreover, task dependent differential brain activities have been linked to anatomical differences across the left-right axis in humans. A good way to further explore this fundamental issue will be to study the functional consequences of subtle changes in neural network formation, which requires that we fully understand DDC system development. As the habenular circuit is evolutionarily highly conserved, researchers have the option to perform such difficult experiments in more experimentally amenable vertebrate systems. Indeed, research in the last decade has shown that the zebrafish is well suited for the study of DDC system development and the phenomenon of functional lateralization. We will critically discuss the advantages of the zebrafish model, available techniques and others that are needed to fully understand habenular circuit

As for the FBR development in Japan, the Atomic Energy Commission revised the long term plan on the research, development and utilization of atomic energy in June, 1994, and under the basic policy that through the considerable period of using LWRs together, FBRs will be adopted as the main nuclear power plants in future, it was decided to establish FBR technology system so that the practical use of FBRs becomes feasible by about 2030 through two demonstration FBRs following the experimental FBR 'Joyo' and the prototype FBR 'Monju'. The Monju started power generation and transmission in August, 1995, but secondary sodium leak accident occurred in December, 1995, and at present it is stopped. The demonstration FBR No. 1 is a top entry type loop reactor, and the power output is about 660 MWe. The start of construction is scheduled at the beginning of 2000s. The research on the whole plant design is carried out as the research on the optimization of demonstration FBR plant for three years from fiscal year 1994. The design of the demonstration FBR No. 1, the research and development for it, the prospect of the practical use and the research and development for the practical use are reported. (K.I.)

46,XY pure gonadal dysgenesis (Swyer syndrome) is characterized by normal female genitalia at birth. It usually first becomes apparent in adolescence with delayed puberty and amenorrhea. Rarely, patients can present with spontaneous breast development and/or menstruation. A fifteen-year-old girl presented to our clinic with the complaint of primary amenorrhea. On physical examination, her external genitals were completely female. Breast development and pubic hair were compatible with Tanner stage V. Hormonal evaluation revealed a hypergonadotropic state despite a normal estrogen level. Chromosome analysis revealed a 46,XY karyotype. Pelvic ultrasonography showed small gonads and a normal sized uterus for age. SRY gene expression was confirmed by multiplex polymerase chain reaction. Direct sequencing on genomic DNA did not reveal a mutation in the SRY, SF1 and WT1 genes. After the diagnosis of Swyer syndrome was made, the patient started to have spontaneous menstrual cycles and therefore failed to attend her follow-up visits. After nine months, the patient underwent diagnostic laparoscopy. Frozen examination of multiple biopsies from gonad tissues revealed gonadoblastoma. With this report, we emphasize the importance of performing karyotype analysis, which is diagnostic for Swyer syndrome, in all cases with primary or secondary amenorrhea even in the presence of normal breast development. We also suggest that normal pubertal development in patients with Swyer syndrome may be associated with the presence of a hormonally active tumor.

Comprehensive Care Plan Development Using Resident Assessment Instrument Framework: Past, Present, and Future Practices

Directory of Open Access Journals (Sweden)

Mary Ellen Dellefield

2015-10-01

Full Text Available Development of the comprehensive care plan (CCP is a requirement for nursing homes participating in the federal Medicare and Medicaid programs, referred to as skilled nursing facilities. The plan must be developed within the context of the comprehensive interdisciplinary assessment framework—the Resident Assessment Instrument (RAI. Consistent compliance with this requirement has been difficult to achieve. To improve the quality of CCP development within this framework, an increased understanding of complex factors contributing to inconsistent compliance is required. In this commentary, we examine the history of the comprehensive care plan; its development within the RAI framework; linkages between the RAI and registered nurse staffing; empirical evidence of the CCP’s efficacy; and the limitations of extant standards of practices in CCP development. Because of the registered nurse’s educational preparation, professional practice standards, and licensure obligations, the essential contributions of professional nurses in CCP development are emphasized. Recommendations for evidence-based micro and macro level practice changes with the potential to improve the quality of CCP development and regulatory compliance are presented. Suggestions for future research are given.

Present status and future development of the European Community rapid information system

International Nuclear Information System (INIS)

Fraser, G.

1990-01-01

Following the Chernobyl reactor accident it was rapidly appreciated that, in addition to upgrading national radiological monitoring systems, action was required to facilitate international communication of the results obtained. The first such system was established by the Vienna Convention, drawn up under the auspices of the IAEA, which came into force in September, 1986. Subsequently the EC Council of Ministers decided in December, 1987, to set up a Community system which in many ways parallels that established by the Convention but differs significantly in certain aspects concerning its legal basis, initiation criteria, data provisions and communications requirements. The present paper describes the present status of the Community system and foreseeable future developments. It is a matter of policy that, to avoid unnecessary complications, this system should be, to the maximum extent practicable, fully compatible with that established by the Convention. Where appropriate, therefore, reference is also made to the latter system

Reduced-activation steels: present status and future development

International Nuclear Information System (INIS)

Klueh, R.L.

2007-01-01

Full text of publication follows: Reduced-activation steels for fusion reactor applications were developed in the 1980's to replace the commercial elevated- temperature steels first considered. In the United States, this involved replacing Sandvik HT9 and modified 9Cr-1Mo steels. Reduced-activation steels, which were developed for more rapid radioactivity decay following exposure in a fusion neutron environment, were patterned after the commercial steels they were to replace. The objective for the reduced-activation steels was that they have strengths (yield stress and ultimate tensile strength from room temperature to 600 deg. C) and impact toughness (measured in a Charpy test) comparable to or better than the steels they were replacing. That objective was achieved in reduced-activation steels developed in Japan, Europe, and the United States. Since the reduced-activation steels were developed in the 1980's, reactor designers have been interested designs for increased efficiency of future fusion plants. This means reactors will need to operate at higher temperatures-above 550 deg. C, which is the upper-temperature limit for the reduced-activation steels. Although the tensile and impact toughness of the reduced-activation steels exceed those of the commercial steels they were patterned after, their creep-rupture properties are inferior to some of the commercial steels they replaced. furthermore, they are much inferior to commercial steels that have been developed since the 1980's. Reasons for why the creep-rupture properties for the new commercial ferritic/martensitic steels are superior to the earlier commercial steels and the reduced-activation steels were examined. The reasons involve compositional changes that were made in the earlier commercial steels to give the new commercial steels their superior properties. Computational thermodynamics calculations were carried out to compare the expected equilibrium phases. It appears that similar changes in composition

Present status of food irradiation and trend of its development

International Nuclear Information System (INIS)

Maha, Munsiah

1998-01-01

Food irradiation has been studied, tested and evaluated intensively for more than 40 years, and at present, this technology has been taking-off for commercial use in many countries. Some 40 countries have approved its application for various food items on groups of food, and about 60 commercial irradiators have been providing irradiation service for food in 29 countries. In 1983, Codex General Standard for Irradiated Food with average irradiation dose limit not exceeding 10 kGy. The latest WHO press release on September 1997 stated that the maximum 10 kGy limit should not be there, since scientific evidences indicated that food irradiated even up to 75 kGy was safe to be consumed, as long as the sensory quality was acceptable and pathogenic organisms had been killed. The development of food irradiation in advanced countries, especially in USA is very significant lately, and hopefully this will be followed by other countries. In Indonesia, application of this technology has been approved since 1987, and six items or groups of food have been cleared for commercial irradiation. Further development and introduction of the technology are still needed to widen its application and to increase public awareness through harmonization of regulations among countries and dissemination of information. In addition, irradiation techniques for some specific purpose using either low dose, medium or high doses should be established to support effective, efficient and economical application. (author)

Under the VAEC, there are three institutes and one center. Status of main facilities, such as TRIGA MARK II, neutron generator, electron accelerator MT-17, and irradiation facilities are outlined in the paper. At present, the VAEC has a total staff of about 540 persons. The number of staff appears adequate to fulfill the present task on application of isotopes and nuclear techniques. When Vietnam decides to develop nuclear power program, the demand for human resources will be significantly high. During the last five years, Vietnam has been developing and implementing a national regulatory program on Radiation Protection and Nuclear Safety. The Ministry of Science, Technology and Environment (MOSTE) have established independent Vietnam Radiation Protection and Nuclear Safety Authority (VRPA) in 1994. If the Vietnamese Government approves the proposed nuclear power program, human resources training should be a key point for all research and development directions at all revel of personnel. When looking back in the history of formation and development of nuclear science and technology in Vietnam, the international cooperation has played an extremely important role in promoting the program. The exchange of information and direct participation in concrete cooperation activities under the framework of the Forum are expected. (Tanaka, Y.)

Pleiotropic effects of a methyl donor diet in a novel animal model.

Directory of Open Access Journals (Sweden)

Kimberly R Shorter

Full Text Available Folate and other methyl-donor pathway components are widely supplemented due to their ability to prevent prenatal neural tube defects. Several lines of evidence suggest that these supplements act through epigenetic mechanisms (e.g. altering DNA methylation. Primary among these are the experiments on the mouse viable yellow allele of the agouti locus (A(vy. In the Avy allele, an Intracisternal A-particle retroelement has inserted into the genome adjacent to the agouti gene and is preferentially methylated. To further test these effects, we tested the same diet used in the Avy studies on wild-derived Peromyscus maniculatus, a native North American rodent. We collected tissues from neonatal offspring whose parents were fed the high-methyl donor diet as well as controls. In addition, we assayed coat-color of a natural variant (wide-band agouti = A(Nb that overexpresses agouti as a phenotypic biomarker. Our data indicate that these dietary components affected agouti protein production, despite the lack of a retroelement at this locus. Surprisingly, the methyl-donor diet was associated with defects (e.g. ovarian cysts, cataracts and increased mortality. We also assessed the effects of the diet on behavior: We scored animals in open field and social interaction tests. We observed significant increases in female repetitive behaviors. Thus these data add to a growing number of studies that suggest that these ubiquitously added nutrients may be a human health concern.

Predictive information processing is a fundamental learning mechanism present in early development: evidence from infants.

Science.gov (United States)

Trainor, Laurel J

2012-02-01

Evidence is presented that predictive coding is fundamental to brain function and present in early infancy. Indeed, mismatch responses to unexpected auditory stimuli are among the earliest robust cortical event-related potential responses, and have been measured in young infants in response to many types of deviation, including in pitch, timing, and melodic pattern. Furthermore, mismatch responses change quickly with specific experience, suggesting that predictive coding reflects a powerful, early-developing learning mechanism. Copyright © 2011 Elsevier B.V.

In Canada, there exists a mature research programme directed towards resolving the nuclear safety and licensing questions surrounding fission product iodine. This integrated programme has had the long term objectives of developing a mechanistic understanding of the important aspects of iodine behaviour in containment, and of producing a mechanistic computer code to predict iodine behaviour under conditions of interest. The research is funded by Canadian Utilities and AECL through the CANDU Owners Group. In parallel with the research, an applications effort is underway to put existing research results into service for the resolution of reactor safety and licensing issues, as well as to identify and develop solutions for more comprehensive problems, such as chemical mitigation strategies to control post-accident iodine release. The present paper describes (a) the present status and objectives of R and D on iodine, its recent evolution and its significant achievements, (b) the analytical tools that are emerging from this programme and (c) existing and planned future applications of the results of the iodine R and D programme. The author concludes with an assessment of the impact that the iodine programme has had on reactor safety and licensing questions in Canada

Present status of computational tools for maglev development

Wang, Z.; Chen, S.S.; Rote, D.M.

1991-10-01

High-speed vehicles that employ magnetic levitation (maglev) have received great attention worldwide as a means of relieving both highway and air-traffic congestion. At this time, Japan and Germany are leading the development of maglev. After fifteen years of inactivity that is attributed to technical policy decisions, the federal government of the United States has reconsidered the possibility of using maglev in the United States. The National Maglev Initiative (NMI) was established in May 1990 to assess the potential of maglev in the United States. One of the tasks of the NMI, which is also the objective of this report, is to determine the status of existing computer software that can be applied to maglev-related problems. The computational problems involved in maglev assessment, research, and development can be classified into two categories: electromagnetic and mechanical. Because most maglev problems are complicated and difficult to solve analytically, proper numerical methods are needed to find solutions. To determine the status of maglev-related software, developers and users of computer codes were surveyed. The results of the survey are described in this report. 25 refs.

Present state of research and development of atomic energy in five Asian countries

Energy Technology Data Exchange (ETDEWEB)

1981-01-01

The survey group for Asian atomic energy cooperation was dispatched by the Japanese government, and toured Philippines, Indonesia, Malaysia, Thailand and Bangladesh from September 7 to 19, 1980. The present state of atomic energy development and the energy situation in respective countries were surveyed through the exchange of opinion and the inspection of related facilities. The Regional Cooperative Agreement for Research, Development and Training Related to Nuclear Science and Technology was concluded in June, 1972, and 12 countries have participated in it. It was impressive that respective countries have the peculiar energy policies corresponding to their objective conditions. They regard atomic energy as the important substitute energy for petroleum, but the fear about the safety of atomic energy and the movement against nuclear power generation have been growing considerably. The research and development on atomic energy are carried out very actively in respective countries, and the construction of large-scale research centers was commenced in Indonesia, Malaysia and Bangladesh. Research reactors have been operated in Philippines, Indonesia and Thailand since about 20 years ago, and the utilization of radioisotopes and radiation has been studied. The cooperation of Japan with these countries is far behind that of other advanced countries.

This paper reports that Japan lacks fossil fuel resources. Consequently, almost all fossil fuels are imported from abroad. Therefore, change in international affairs affects on Japan's politics and social life, as learned from experience of economic social life, as learned from experience of economic confusion caused by the oil crisis of 1973. For this reason, research and development (R and D) of alternative energy technologies was initiated in July 1974, which was promoted as one of national energy development programs called Sunshine Project. Presently, their technical developments are being continued to put practical use under this project. However, Japan's dependency of primary energy resources on oil is still high among major advanced countries and energy supply structure is significantly weak. Furthermore, from indetermination of the recent political condition in the Middle East, the importance of security against supply and demand of petroleum in middle and long term is generally recognized with the increasing cost of oil

A {sup 129}Xe comagnetometer designed for the measurement of neutron electric dipole moment (nEDM) as precisely as 1 × 10{sup −27}e cm is presented. Highly nuclear spin polarized {sup 129}Xe are introduced into an EDM cell where the {sup 129}Xe spin precession is detected by means of the two-photon transition. The geometric phase effect (GPE) which generates the false nEDM was quantitatively discussed and the systematic error of nEDM from the GPE was estimated considering the buffer-gas suppression due to Xe atomic collisions. Research and development are in progress to construct the {sup 129}Xe comagnetometer with a field sensitivity of 0.3 fT. At present, about 70 % nuclear spin polarized {sup 129}Xe atoms have been obtained in a spin exchange opitial pumping cell, that are in the process of being transferred into the EDM cell via a cold trap.

2013-12-01

In a partnership last Spring with Arizona Public Service, the National Optical Astronomy Observatory (NOAO) created the 'Dark-Skies Energy Education Program: Energy Awareness for a Sustainable Future'. In this program, experienced science and technology education specialists from NOAO led 2 one-day professional development workshops for thirteen 6th grade teachers on dark skies and energy education. The workshops focused on three foundational, scaffolding activities and a final student research project. This in turn culminated in a Family Science Night where students presented their projects. In between these events, our NOAO team provided support for teachers through real-time video conferencing using FaceTime. In addition to the professional development, each teacher received a kit full of resource materials to perform the activities and research project. The kit was at no cost to the teacher, school, or district. Each kit contained the latest version of a tablet, which was used to facilitate communication and support for the teachers, as well as provide all the program's written teaching materials. The activities are in accordance with state, Common Core and Next Generation Science Standards. Our NOAO instructors gave firsthand experiences on how best to use these materials in a classroom or public setting. They also discussed opportunities on how they can incorporate, adapt and expand upon the activities and research projects in the classroom. Evaluation reports from the program's independent evaluator showed that the students enjoyed learning from the three foundational activities and research projects. The project presentations by the Yuma students were outstanding in their creativity, level of effort, and scientific accuracy. To summarize the evaluations, significant changes in knowledge and attitude were made with the teachers and students (from one-on-one interviews and surveys), but behavioral changes (albeit only over a semester) seemed minimal.

Boiler recirculation pumps are important components of modern power stations. The development of large recirculation pumps up to a driving power of 1,500 kW was faced with some problems in meeting the plant requirements. In this paper, the present state of development is dealt with. The development problems in the fields of hydrodynamics, cavitation, corrosion and erosion are dealt with as well as the problems of the design of the casing with regard to thermodynamics and strength. Finally, operational experience with the boiler recirculation pump for 600 MW power stations will be reported on. (orig./AK) [de

Women’s Participation in Africa’s Nuclear Development-Challenges and Opportunities (Poster Presentation)

International Nuclear Information System (INIS)

Mkhosi-Motsaathebe, M.

2015-01-01

Expansion of nuclear technologies and plans for new plants in Africa makes this an exciting time for more women to be involved in the nuclear sector and there are lots of opportunities across the nuclear value chain for women to be involved. In recent decades, more and more women are are now entering the nuclear field and many people are starting to recognise opportunities for women, since the role played by women in the nuclear field enhances the development goals for many countries. In developing countries and in Africa in particular, however, there is a greater need for awareness of women’s involvement in STEM fields in general, and to change prevailing attitudes about women’s participation in the nuclear science and technology in particular. This paper will look at various opportunities women have in the expanding nuclear sector in the continent, and how these opportunities can be utilised, not only for those in sciences but also in business disciplines. The approaches organizations and countries can take in broadening participation of the female gender in the nuclear development in Africa; will also be presented, as well as how to address the challenges faced by women in the dynamic nuclear field.

Development of Molecularly Imprinted Polymers to Target Polyphenols Present in Plant Extracts

Directory of Open Access Journals (Sweden)

Catarina Gomes

2017-11-01

Full Text Available The development of molecularly imprinted polymers (MIPs to target polyphenols present in vegetable extracts was here addressed. Polydatin was selected as a template polyphenol due to its relatively high size and amphiphilic character. Different MIPs were synthesized to explore preferential interactions between the functional monomers and the template molecule. The effect of solvent polarity on the molecular imprinting efficiency, namely owing to hydrophobic interactions, was also assessed. Precipitation and suspension polymerization were examined as a possible way to change MIPs morphology and performance. Solid phase extraction and batch/continuous sorption processes were used to evaluate the polyphenols uptake/release in individual/competitive assays. Among the prepared MIPs, a suspension polymerization synthesized material, with 4-vinylpyridine as the functional monomer and water/methanol as solvent, showed a superior performance. The underlying cause of such a significant outcome is the likely surface imprinting process caused by the amphiphilic properties of polydatin. The uptake and subsequent selective release of polyphenols present in natural extracts was successfully demonstrated, considering a red wine solution as a case study. However, hydrophilic/hydrophobic interactions are inevitable (especially with complex natural extracts and the tuning of the polarity of the solvents is an important issue for the isolation of the different polyphenols.

NATURE CONSERVATION MOVEMENT IN THE WORLD: ITS HISTORICAL DEVELOPMENT AND PRESENT SITUATION

2007-04-01

Full Text Available Although nature conservation is a well recognized topic at present, it is not a new phenomenon. Throughout history, there are numerous examples of efforts made by governments, rulers, or individual land owners to protect certain land areas that possessed unique natural values. While many of these areas were actually isolated as game preserves for hunting, they were also designed to conserve wildlife. The establishment of Yellowstone National Park in 1972 marks the modern concept of a national park as it was designed on a very large protected natural area. Presently, one of the most efficient ways for nature protection is “area conservation approach” that many organizations have been developing various systems and categories about. Unfortunately, in spite of such improvements and the extension of the protected area network, many of these areas are not properly protected and/or managed in some countries. This study summarizes the historical evolution of nature conservation systems and strategies in the world with the related international legislative aspects as well. As it stated in this paper, USA and Europa have a well known history on nature conservation and show great concern in respect to participating to the international convention and arrangements.

The past, present, and future of health development campaigns: reflexivity and the critical-cultural approach.

Science.gov (United States)

Dutta, Mohan Jyoti; de Souza, Rebecca

2008-07-01

In contemporary society, health issues have gained increasing urgency in both political and academic spheres. Looking back at the failure of the modernist development initiatives, there is the need to realize that we live in a time of increasing sociopolitical complexity. The present moment is perhaps best understood in terms of a complex tension and linkage between the past and present, global and local, modern and postmodern. The critical-cultural approach to health campaigns is an approach that, through the reflexive interrogation of modernist assumptions underlying health communication campaigns, attempts to foreground the tensions inherent in the practice of health campaigns. This essay discusses the manner in which the critical-cultural approach interrogates modernist assumptions and provides an alternative paradigm for approaching the theory and practice of health campaigns by suggesting the necessity for reflexivity. Specifically, we discuss how the perspective interrogates the role of the media in development, the significance of culture, the locus of health responsibility, the impact of structural conditions, and the politics of knowledge, providing examples of campaigns that illustrate this reflexivity.

The development of halophyte-based agriculture: past and present.

Science.gov (United States)

Ventura, Yvonne; Eshel, Amram; Pasternak, Dov; Sagi, Moshe

2015-02-01

Freshwater comprises about a mere 2·5% of total global water, of which approximately two-thirds is locked into glaciers at the polar ice caps and on mountains. In conjunction with this, in many instances irrigation with freshwater causes an increase in soil salinity due to overirrigation of agricultural land, inefficient water use and poor drainage of unsuitable soils. The problem of salinity was recognized a long time ago and, due to the importance of irrigated agriculture, numerous efforts have been devoted towards improving crop species for better utilization of saline soils and water. Irrigating plants with saline water is a challenge for practitioners and researchers throughout the world. Recruiting wild halophytes with economic potential was suggested several decades ago as a way to reduce the damage caused by salinization of soil and water. A range of cultivation systems for the utilization of halophytes have been developed, for the production of biofuel, purification of saline effluent in constructed wetlands, landscaping, cultivation of gourmet vegetables, and more. This review critically analyses past and present halophyte-based production systems in the context of genetics, physiology, agrotechnical issues and product value. There are still difficulties that need to be overcome, such as direct germination in saline conditions or genotype selection. However, more and more research is being directed not only towards determining salt tolerance of halophytes, but also to the improvement of agricultural traits for long-term progress. © The Author 2014.

Ando, Takekazu; Tsuchiya, Yuichiro; Kodera, Yoshie

2005-04-01

When network distribution of movie files was considered as reference, it could be useful that the lossy compression movie files which has small file size. We chouse three kinds of coronary stricture movies with different moving speed as an examination object; heart rate of slow, normal and fast movies. The movies of MPEG-1, DivX5.11, WMV9 (Windows Media Video 9), and WMV9-VCM (Windows Media Video 9-Video Compression Manager) were made from three kinds of AVI format movies with different moving speeds. Five kinds of movies that are four kinds of compression movies and non-compression AVI instead of the DICOM format were evaluated by Thurstone's method. The Evaluation factors of movies were determined as "sharpness, granularity, contrast, and comprehensive evaluation." In the virtual bradycardia movie, AVI was the best evaluation at all evaluation factors except the granularity. In the virtual normal movie, an excellent compression technique is different in all evaluation factors. In the virtual tachycardia movie, MPEG-1 was the best evaluation at all evaluation factors expects the contrast. There is a good compression form depending on the speed of movies because of the difference of compression algorithm. It is thought that it is an influence by the difference of the compression between frames. The compression algorithm for movie has the compression between the frames and the intra-frame compression. As the compression algorithm give the different influence to image by each compression method, it is necessary to examine the relation of the compression algorithm and our results.

Full Text Available Romania's participation in the implementation of EU regional policy means, first opportunity to benefit from a system of values that can be found between economic efficiency, environmental protection,ensuring minimum standards of existence, the definition of a "European lifestyle, urban values, qualified human resources. Moreover, European integration and openness to the EU internal market and the challenge involves increasing competitiveness, which can negatively affect the process of building an economy, like Romania. In this context, structural instruments are the most important resource that Romania will have to face the challenges of change and integration. However, regional development policy can not solely be the key to overall development of a state, especially in terms of its actual effects on growth are difficult to assess. A critical dimension of this is represented on the nature of economic and quality of other public policies that form the core of economic policy mix of a state: the legal protection of property rights and market economy, taxation, antitrust, etc.

A framework for visualization of battlefield network behavior

Science.gov (United States)

Perzov, Yury; Yurcik, William

2006-05-01

An extensible network simulation application was developed to study wireless battlefield communications. The application monitors node mobility and depicts broadcast and unicast traffic as expanding rings and directed links. The network simulation was specially designed to support fault injection to show the impact of air strikes on disabling nodes. The application takes standard ns-2 trace files as an input and provides for performance data output in different graphical forms (histograms and x/y plots). Network visualization via animation of simulation output can be saved in AVI format that may serve as a basis for a real-time battlefield awareness system.

Within the European Union, the two major breeding blanket concepts presently being developed are the helium cooled pebble bed (HCPB), and the helium cooled lithium lead (HCLL) blankets. For both concepts, different conceptual designs are being discussed with temperature windows in the range 250-550 deg. C for conservative approaches based on reduced activation ferritic-martensitic (RAFM) steels, and in the range 250-650 deg. C for more advanced versions, taking into account oxide dispersion strengthened (ODS) steels. As a final result of a systematic development of RAFM-steels in Europe, the 9% CrWVTa alloy EUROFER was specified and produced in an industrial scale with a variety of product forms. A large characterisation program is being performed including irradiation in materials test reactors between 60 and 450 deg. C ({<=}15 dpa), and in a fast breeder reactor at 330 deg. C up to 30 dpa. EUROFER is resistant to high temperature ageing, and the existing creep-rupture data ({approx}30,000 h, 450-600 deg. C) indicate long-term stability and predictability. The ODS variant of EUROFER shows superior tensile and creep properties compared to EUROFER. Applying a new production route has diminished the problem of lower ductility and inferior impact properties. A reliable joining technique for ODS and RAFM steels employing diffusion welding was successfully developed.

The development of FBRs in Japan now reached the stage to conclude on the development organization for a demonstration reactor positioning one step before a practical reactor. FBRs can be operated while converting uranium-238 existing in natural uranium by 99.3% to fissile plutonium-239, as the result, the nuclear fuel more than that consumed can be produced. However, there are various technical difficulties in FBRs, and the construction cost is estimated to be considerably higher as compared with that of LWRs. Also the plutonium obtained by reprocessing spent fuel is used for FBRs, accordingly, the development of FBRs is inseparable from the establishment of nuclear fuel cycle. In order to get rid of the burden of enormous development cost for FBRs, the trend of international joint development is conspicuous. The Superphenix with 1200 MWe output under construction centering around SERENA is expected to attain the criticality in the spring of 1985. For the development of a demonstration reactor, it is necessary to increase the role of private businesses, and the smooth transfer of know-how accumulated in Power Reactor and Nuclear Fuel Development Corp. to civilian side is an important problem.

European Cooperation For the Development of Advanced PWR : Present Status and Future Objective

This agreement is above all an expression of the confidence in the future role of nuclear energy as an important energy source in electricity generation despite the present difficult situation in this market. This situation is today characterized by a saturation in many industrialized countries and by stretching or even postponing nuclear programs in many developing and newly industrialized countries under the impression of the Chernobyl accident and the related wave of anti-nuclear movements and due to the fact that the financing requirements of such nuclear power programs simply exceeded the available possibilities. However, a number of well-known facts justify the expectation that a revival of the nuclear market will take place in the foreseeable future. On the one hand it is evident that the electricity consumption will continue to increase significantly due to the population growth and the urgently needed improvement in the standard of living in many countries. On the other hand the extension of the use of fossil fuels increasingly raises concerns about the environmental consequences as well as about the future price development of such fuels. In addition it becomes more and more clear, that the dreams of phasing-out nuclear without several countries and political parties cannot be fulfilled. One of the important positive signs may be the justified hope of a revival of the nuclear market in the United States of America which in turn will certainly have a positive effect on the nuclear business in other areas. Thus we believe that the market is presently undergoing a difficult transition phase during which the suppliers have to prepare themselves for the challenge of the future. This assessment and the general trend of cooperation and concentration of the world's power plants industry was the basis for the cooperation between Fumarate and Siemens

2007-01-01

Topics of computer-aided detection (CAD) are reviewed. Commercially available, Food and Drug Administration (FDA)-approved CAD systems are for fields of breast cancer (mammography), chest (flat X-ray and CT imaging) and colon (polyp detection). In Japan, only mammography CAD is approved. Efficacy of CAD is controversial, for which reliable database is important, and its construction is under development in various medical fields. Digitalized image is now popularized, which conceivably leads to improve the cost-effectiveness of diagnosis with CAD. For incentive, approval for health insurance would be the case as seen in the increased CAD sale by R2 Technology Co., and MHLW actually assists facilities to introduce the reading-aid system of mammography by sharing a half of its cost. There are 2 big projects for CAD study supported by MECSST, which the author concerns. One is the development of diagnostic aid for the multi-dimensional medical images where the multi-organ, multi-disease CAD system is considered. The other involves the CAD in brain MRI, in breast US and in eyeground picture. It is not in so far future for patients and doctors to fully enjoy the benefit of CAD. (R.T.)

As for other imaging sensor markets, whatever is the technology, the commercial spread of terahertz (THz) cameras has to fulfil simultaneously the criteria of high sensitivity and low cost and SWAP (size, weight and power). Monolithic silicon-based 2D sensors integrated in uncooled THz real-time cameras are good candidates to meet these requirements. Over the past decade, LETI has been studying and developing such arrays with two complimentary technological approaches, i.e. antenna-coupled silicon bolometers and CMOS Field Effect Transistors (FET), both being compatible to standard silicon microelectronics processes. LETI has leveraged its know-how in thermal infrared bolometer sensors in developing a proprietary architecture for THz sensing. High technological maturity has been achieved as illustrated by the demonstration of fast scanning of large field of view and the recent birth of a commercial camera. In the FET-based THz field, recent works have been focused on innovative CMOS read-out-integrated circuit designs. The studied architectures take advantage of the large pixel pitch to enhance the flexibility and the sensitivity: an embedded in-pixel configurable signal processing chain dramatically reduces the noise. Video sequences at 100 frames per second using our 31x31 pixels 2D Focal Plane Arrays (FPA) have been achieved. The authors describe the present status of these developments and perspectives of performance evolutions are discussed. Several experimental imaging tests are also presented in order to illustrate the capabilities of these arrays to address industrial applications such as non-destructive testing (NDT), security or quality control of food.

Applied and industrial activities at the ESRF: Present status and future development

CERN Document Server

Doucet, J

2003-01-01

Be it proteins, new superconductors, polymers or ferro-magnetic compounds, fundamental research is laying foundations for possible technical applications as well as industrial exploitation. At the ESRF, industrial companies can be involved in two main ways, depending on the type of research they are interested in. The first concerns beam time allocation for non-proprietary and fully-published research, the procedure is the same as for public laboratories. The second concerns the proprietary research, for which a fee is charged and where results are kept confidential. The use of synchrotron radiation for the characterisation of materials is certain to play a crucial role in the development of new materials in the close future. It is a policy of the ESRF that European industry should share the benefit of its facilities.

Massive migration and increasing population in Malaysia has contributed to the increasing demand of quality and affordable housing. Over the past 50 years, the Malaysian housing industry has seen the growth of using conventional construction system such as reinforced concrete frame structures and bricks. The conventional system, as agreed by many researchers, causes delays and other disadvantages in some of the construction projects. Thus, the utilization of interlocking loadbearing hollow block (ILHB) system is needed to address these issues. This system has been identified as an alternative and sustainable building system for the construction industry in Malaysia which the PUTRA block system is the latest example of the ILHB developed. The system offers various advantages in terms of speed and cost in construction, strength, environmentally friendly and aesthetic qualities. Despite these advantages, this system has not been practically applied and develop in Malaysia. Therefore, this paper aims to review the past and present development of the interlocking loadbearing hollow block (ILHB) system that available locally and globally.

The Earth Clouds, Aerosols and Radiation Explorer (EarthCARE) mission is joint mission between Europe and Japan for the launch year of 2018. Mission objective is to improve scientific understanding of cloud-aerosol-radiation interactions that is one of the biggest uncertain factors for numerical climate and weather predictions. The EarthCARE spacecraft equips four instruments such as an ultra violet lidar (ATLID), a cloud profiling radar (CPR), a broadband radiometer (BBR), and a multi-spectral imager (MSI) and perform complete synergy observation to observe aerosols, clouds and their interactions simultaneously from the orbit. Japan Aerospace Exploration Agency (JAXA) is responsible for development of the CPR in this EarthCARE mission and the CPR will be the first space-borne W-band Doppler radar. The CPR is defined with minimum radar sensitivity of -35dBz (6dB better than current space-borne cloud radar, i.e. CloudSat, NASA), radiometric accuracy of 2.7 dB, and Doppler velocity measurement accuracy of less than 1.3 m/s. These specifications require highly accurate pointing technique in orbit and high power source with large antenna dish. JAXA and National Institute of Information and Communications Technology (NICT) have been jointly developed this CPR to meet these strict requirements so far and then achieved the development such as new CFRP flex-core structure, long life extended interaction klystron, low loss quasi optical feed technique, and so on. Through these development successes, CPR development phase has been progressed to critical design phase. In addition, new ground calibration technique is also being progressed for launch of EarthCARE/CPR. The unique feature of EarthCARE CPR is vertical Doppler velocity measurement capability. Vertical Doppler velocity measurement is very attractive function from the science point of view, because vertical motions of cloud particles are related with cloud microphysics and dynamics. However, from engineering point of

Based on the Long-term Program for Development and Utilization of Nuclear Energy which was revised in 1987, the Japan Atomic Energy Research Institute (JAERI) has carried out the Research and Development (R and D) on the High Temperature Gas-cooled Reactors (HTGRs) in Japan. The JAERI obtained the installation permit of the High Temperature Engineering Test Reactor (HTTR) from the Government in November 1990 and started the construction of the HTTR facility in the Oarai Research Establishment in March 1991. The HTTR is a test reactor with thermal output of 30MW and outlet coolant temperature of 850degC at the rated operation and 950degC at the high temperature test operation, using the pin-in-block type fuel, and has capability to demonstrate nuclear process heat utilization. The reactor pressure vessel and intermediate heat exchanger were installed in the reactor containment vessel in 1994, and reactor internals were also installed in the reactor pressure vessel in 1995. The first criticality will be attained in December 1997. This report describes the design outline and construction progress of the HTTR, R and D of fuel, materials and components for the HTGR and high temperature nuclear heat application, and innovative and basic researches for high temperature technologies at the HTTR.

Present status of developing petroleum-substituting energy (EC)

Science.gov (United States)

1993-03-01

The EC has had approximately 50% of its total energy demand supplied by imports from the exterior of the Community. Hence, it is getting important to develop oil-substituting renewable energy as well as to curtail the emission of carbon dioxide. In consideration of these situations, the results of investigation on the energy policy of the European Community are described. The policy comprises three courses: European Energy Charter, formation of an open European Community energy market, and environmental conservation. Particularly, concerning the reduction of carbon dioxide emission, the EC Council has decided to introduce carbon dioxide taxation so as to suppress the carbon dioxide emission in the year 2000 to the 1990 level. The arrangement for its introduction, however, encountered with difficulties because of the opposition of various countries other than the European Community and the industrial world of the European Community. Legislation of the investment promotion law for energy saving and the construction of infrastructure footing and an information network are ineffective due to the sluggish fuel price and economic recession. A plurality of EC member countries are advancing a comprehensive activity within the framework of the joint programs of research, development, and demonstration set for the renewable energy policy ensuring energy supply and environmental harmonization.

Sreehari, R.

1993-01-01

A high-sensitivity airborne gamma-ray spectrometric and magnetic survey system, using Na(Tl) detector volume of 50,000 cc for 4π and 4195 cc for 2π geometry applications, was designed, developed, and fabricated in 1978 and was flown for airborne surveys in various parts of India for over a decade. A compact complementary metal-oxide-semiconductor (CMOS) logic circuit based high-sensitivity airborne gamma-ray spectrometric and magnetic survey system with high noise-immunity using Na(Tl) detector volume of 50,000 cc for 4π and 12,500 cc for 2π geometry applications was developed and interfaced to an Inertial Navigation System in 1988. The system currently in use was flown extensively for airborne surveys in various parts of India for the Atomic Minerals Division, Oil and Natural Gas Commission, and Nuclear Power Corporation. The design aspects of the present system have been discussed. A microprocessor based DDAS and multichannel analysers, having on-line micro terminal and on-line corrections for Compton scatter, and background radiation to obtain corrected analog profiles for the spectrometric data, are currently under development. The design aspects of these units are described and evaluated for future high-sensitivity airborne gamma-ray spectrometric surveys with Nal(Tl) detector volumes similar to those of the present system.

The Expected Net Present Value of Developing Weight Management Drugs in the Context of Drug Safety Litigation.

Science.gov (United States)

Chawla, Anita; Carls, Ginger; Deng, Edmund; Tuttle, Edward

2015-07-01

Following withdrawals, failures, and significant litigation settlements, drug product launches in the anti-obesity category slowed despite a large and growing unmet need. Litigation concerns, a more risk-averse regulatory policy, and the difficulty of developing a product with a compelling risk-benefit profile in this category may have limited innovators' expected return on investment and restricted investment in this therapeutic area. The objective of the study was to estimate perceived manufacturer risk associated with product safety litigation and increased development costs vs. revenue expectations on anticipated return on investment and to determine which scenarios might change a manufacturer's investment decision. Expected net present value of a weight-management drug entering pre-clinical trials was calculated for a range of scenarios representing evolving expectations of development costs, revenue, and litigation risk over the past 25 years. These three factors were based on published estimates, historical data, and analogs from other therapeutic areas. The main driver in expected net present value calculations is expected revenue, particularly if one assumes that litigation risk and demand are positively correlated. Changes in development costs associated with increased regulatory concern with potential safety issues for the past 25 years likely did not impact investment decisions. Regulatory policy and litigation risk both played a role in anti-obesity drug development; however, product revenue-reflecting efficacy at acceptable levels of safety-was by far the most important factor. To date, relatively modest sales associated with recent product introductions suggest that developing a product that is sufficiently efficacious with an acceptable level of safety continues to be the primary challenge in this market.

The study aimed to evaluate 1-year outcomes of the multicentre PREVAIL transapical (TA) study of TA-aortic valve implantation (AVI) in high-risk patients. From September 2009 to August 2010, a total of 150 patients, aged 81.6 ± 5.8 years, 40.7% female, were included at 12 European TA-AVI experienced sites. Patients received 23 (n = 36), 26 (n = 57) and 29 mm (n = 57) second-generation SAPIEN XT™ (Edwards Lifesciences, Irvine, CA, USA) valves. The mean logistic EuroSCORE was 24.3 ± 7.0, and mean Society Thoracic Surgeons score was 7.5 ± 4.4%. Survival was 91.3% at 30 days and 77.9% at 1 year. Subgroup analysis revealed survivals of 91.7/88.9, 86.0/70.2, 96.55/91.2% for patients receiving 23-, 26- and 29-mm valves at 30 days and at 1 year, respectively. Transthoracic echocardiography revealed preserved left ventricular ejection fraction and low gradients. Aortic incompetence was none in 41/48, trace 30/36, mild 22/12 and moderate in 7/4% at discharge and 1 year. Walking distance increased from 221 (postimplant) to 284 m (at 1 year, P = 0.0004). Three patients required reoperation due to increasing aortic incompetence during follow-up. Causes of mortality at 1 year were cardiac (n = 7), stroke (n = 1) and others (n = 5). The European PREVAIL multicentre trial demonstrates good functionality and good outcomes for TA-AVI using the second-generation SAPIEN XT prosthesis and the ASCENDRA-II delivery system. The 29-mm SAPIEN XT valve was successfully introduced and showed excellent results.

This invited keynote paper is the most recent among similar reviews published by the author, update to year 2011. In a format similar to that in past reviews, recent estimates and forecasts of the conventional fossil fuel resources and their reserve/production ratio, nuclear power, and renewable energy potential, and energy uses are surveyed. A brief discussion of the status, sustainability (economic, environmental and social impact), and prospects of fossil, nuclear and renewable energy use, and of power generation is presented. Beyond the general review, the paper focuses this year on some of the many important areas that deserve more attention: (1) the recently emerging game-changing developments of postponement of “peak oil”, nuclear power future following the disaster in Japan, and effects of the recent global economy downturn of global sustainability, (2) the potential and impacts of electric cars (3) the often neglected energy status and promising potential of Africa. Some ways to resolve the problem of the availability, cost, and sustainability of energy resources alongside the rapidly rising demand are discussed. The author’s view of the promising energy R and D areas, their potential, foreseen improvements and their time scale, and last year’s trends in government funding are presented.

A Systematic Review of Barriers to Breast Cancer Care in Developing Countries Resulting in Delayed Patient Presentation

Directory of Open Access Journals (Sweden)

Ketan Sharma

2012-01-01

Full Text Available Background. Within the developing world, many personal, sociocultural, and economic factors cause delayed patient presentation, a prolonged interval from initial symptom discovery to provider presentation. Understanding these barriers to care is crucial to optimizing interventions that pre-empt patient delay. Methods. A systematic review was conducted querying: PubMed, Embase, Web of Science, CINAHL, Cochrane Library, J East, CAB, African Index Medicus, and LiLACS. Of 763 unique abstracts, 122 were extracted for full review and 13 included in final analysis. Results. Studies posed variable risks of bias and produced mixed results. There is strong evidence that lower education level and lesser income status contribute to patient delay. There is weaker and, sometimes, contradictory evidence that other factors may also contribute. Discussion. Poverty emerges as the underlying common denominator preventing earlier presentation in these settings. The evidence for sociocultural variables is less strong, but may reflect current paucity of high-quality research. Conflicting results may be due to heterogeneity of the developing world itself. Conclusion. Future research is required that includes patients with and without delay, utilizes a validated questionnaire, and controls for potential confounders. Current evidence suggests that interventions should primarily increase proximal and affordable healthcare access and secondarily enhance breast cancer awareness, to productively reduce patient delay.

Technical advances in the design of medical accelerators are making possible the exploration of new treatment techniques. Technology currently available to the radiation oncologist allows the use of internal and dynamic wedges. Multileaf collimators can be used for static treatment ports, and dynamic field shaping and beam modulation using multileaf collimators has been shown to be feasible. Computer interfaces are necessary to transfer the complex treatment sequences that are possible with these devices. Such network interfaces also provide for more efficient conventional treatments. New machines such as X-band linear accelerators and advanced proton accelerators are being developed for applications such as boron neutron capture therapy and proton conformal therapy.

The Cyclicity of the Development of the Global Economic System amid Present-Day Globalization

Directory of Open Access Journals (Sweden)

Mihail N. Dudin

2014-10-01

Full Text Available The relevance of this topic is associated with the diversity of causes behind crisis processes in economics and the individuality of each particular crisis. This necessitates classifying them in a detailed fashion. The present downturn is a manifestation of the cyclicity of the development of the global economic system amid present-day globalization and the established architecture of the institutional space. The formal (legislation, contractual rules, corporate norms, etc. and non-formal institutes (rules, customs, traditions, behavior as a whole, etc., undergoing changes in their structure and mechanisms, caused the emergence of financial innovations whose yield surpassed that of the real sector of the economy multifold. This facilitated the concentration of money in financial markets and transforming them into a thing-in-itself. The theory of economic cycles is one of the theories of economic dynamics which explain the movement of the national economy. While the theory of economic growth explores factors and conditions for growth as a long-term trend, the theory of cycles deals with causes behind fluctuations in economic activity through time. Results. In accordance with the aims of this study, the authors established that crises can have the following causes: objective, which are associated with the cyclical development of the system, modernization and restructuring needs, and the impact of external factors, and subjective, which reflect errors in management, shortcomings in the organization of production, and the imperfections of innovation and investment policy. A crisis can take its course manifestly and be easily detected or can be inconspicuous and take its course in a latent form. The most dangerous are crises that affect the system as a whole. In a situation of this kind, there forms a train of complex issues resolving which depends on the timeliness of detecting them and professionalism in managing the organization, municipal

India's Integrated Child Development Services (ICDS) was established in 33 projects in 1975 and is spread over 22 states; 67 additional projects were begun in 1977, and over the next 2 years; 100 additional projects were added. By 1991=92, coverage was almost 50% of the country with 2696 projects; the expectation is for 100% coverage by the year 2000. An infrastructure chart identifies the organization and integration between level and social welfare and health departments. Objectives are clearly identified and the departments functionally linked. Linkages are achieved by shared space and activities at various levels. Over the past 17 years, services have included minimum needs programs, integrated rural development and poverty alleviation, national health policy and education policy, universal immunization, and the development of women and children in rural areas. ICDS is sponsored 100% by the status and uniquely relies on the honorary anganwadi worker (AWW), who is a woman, recruited and chosen by the community, aged 21-45 years and middle-school educated. The AWW was responsibility for 2000 households or 1000 persons in rural areas and 700 persons in tribal areas. The AWW is crucial to the functioning of the program and receives an honorarium of Rs. 225-275/month for implementing the ICDs program; AWWs have helpers who are paid Rs. 110/month. Training over a 3-year period is conducted at the Bal Sevika Training Institute by the Indian Council of Child Welfare. Additional health personnel and their role and the number of persons/per area AWWS are responsible for, equipment, and functions are also described. The AWW is responsible for nonformal preschool education, organization of supplementary nutrition feeding, health and nutrition education of women and families, immunization of women and children, treatment and referral of common illnesses, growing monitoring, and community participation. Presently, there are 2506 central sector projects and 190 state sector

The prevalence of phenotypic females with a 46,XY karyotype is low, thus current knowledge about age and clinical presentation at diagnosis is sparse even for the most frequent conditions, androgen insensitivity syndrome (AIS), and gonadal dysgenesis. To estimate incidence, prevalence, age at diagnosis, and clinical presentation at diagnosis in 46,XY females. A nationwide study covering all known females with a 46,XY karyotype in Denmark since 1960. The diagnosis of 46,XY disorder of sex development (DSD) was determined by medical record evaluation, data from the Danish National Patient Registry, and genetic testing, if available. A total of 166 females registered as 46,XY females in the Danish Cytogenetic Central Registry were identified. A total of 124 females were classified as having 46,XY DSD, 78 with AIS and 25 with gonadal dysgenesis, whereas the remaining subjects had a variety of different diagnoses. The prevalence of 46,XY females was 6.4 per 100 000 live born females, and for AIS and gonadal dysgenesis, it was 4.1 and 1.5 per 100 000, respectively. Median age at diagnosis was 7.5 years (95% confidence interval, 4.0-13.5; range, 0-34 y) in AIS and 17.0 years (95% confidence interval, 15.5-19.0; range, 0-28 y) in gonadal dysgenesis (P = .001). Clinical presentation was dependent on cause of DSD. The first estimate on prevalence of 46,XY females is 6.4 per 100 000 live born females. The presentation of AIS and gonadal dysgenesis is distinctly different, with AIS being diagnosed during childhood and gonadal dysgenesis during pubertal years. The presenting phenotype is dependent on the cause of 46,XY DSD.

This paper discusses alarm filtering and presentation in the control room of nuclear and other process control plants. Alarm generation and presentation is widely recognized as a general process control problem. Alarm systems often fail to provide meaningful alarms to operators. Alarm generation and presentation is an area in which computer aiding is feasible and provides clear benefits. Therefore, researchers have developed several computerized alarm filtering and presentation approaches. This paper discusses problems associated with alarm generation and presentation. Approaches to improving the alarm situation and installation issues of alarm system improvements are discussed. The impact of artificial intelligence (AI) technology on alarm system improvements is assessed. (orig.)

The gas turbine is the most widely used prime mover all over the world for either power generation or mechanical drive applications. The above fact is due to the recent great improvements that have been done especially in terms of efficiency, availability and reliability. The future for gas turbine technological development looks very promising. In fact, although tremendous growth has already taken place, there is still the potential for dramatic improvements in performance. Compared with the competitive prime movers (conventional steam power plants and reciprocating piston engines) the gas turbine technology is younger and still following a strong growth curve. The coming decades will witness the continued increasing in turbine inlet temperature, the development of new materials and refrigeration systems and the commercialization of inter cooled system and steam cooled turbines. With the very soon introduction of the {sup G }and {sup H }technology, expected single and combined cycle efficiencies for heavy duty machines are respectively 40% and 60%, while maintaining single digit levels in pollutant emissions. In this report are given wide information on gas turbine present technology (Thermodynamics, features, design, performances, emission control, applications) and are discussed the main lines for the future developments. Finally are presented the research and technological development activities on gas turbine of Italian National Agency for new Technology Energy and the Environment Energy Department.

Present status and further objectives of SNR fuel element development

International Nuclear Information System (INIS)

Karsten, G.

Within the scope of the fuel element development program for the fast breeder reactor SNR 300, 500 fuel pins have been irradiated since 1964, 250 of them in fast flux. Results indicate that the maximum nominal target burnup of 90.000 MWd/t of the SNR 300 Mk Ia possibly can be reached. The main problems, which arise from clad swelling and internal corrosion, can be met by special pretreatments of the austenitic stainless steel 1.4970 and a fuel stoichiometry of 1.97. Beyond this target burnup either material property improvements have to be made or burnup reductions have to be accepted. The remaining questions can be answered by the use of the SNR 300 as a test reactor. A further target is the development of a carbide fuel element, which should be very effective in a high power breeder reactor because of its low fissile inventory and high breeding gain. This development program will also be finalized in the SNR 300. (U.S.)

2014-01-01

Full Text Available Background: The literature on paediatric osteomyelitis in the developing world is scarce, and there have been calls for further characterisation of its epidemiology and the identification of factors that limit effective management in order to guide local service delivery. Our centre is a hospital serving a population of 11 million people in Tanzania. Materials and Methods: We identified patients 3 months. Twelve out of 13 with a time from symptom onset to presentation of <2 months did not develop recurrence. Conclusions: This is, to the best of our knowledge, the second largest study of paediatric osteomyelitis in the developing world. Major challenges facing this centre include a lack of availability of bacterial cultures and failure to attend follow-up. Delayed presentation of osteomyelitis to our centre is associated with recurrence of infection.

Visual rehabilitation: visual scanning, multisensory stimulation and vision restoration trainings

Directory of Open Access Journals (Sweden)

2015-07-01

Full Text Available Neuropsychological training methods of visual rehabilitation for homonymous vision loss caused by postchiasmatic damage fall into two fundamental paradigms: compensation and restoration. Existing methods can be classified into three groups: Visual Scanning Training (VST, Audio-Visual Scanning Training (AViST and Vision Restoration Training (VRT. VST and AViST aim at compensating vision loss by training eye scanning movements, whereas VRT aims at improving lost vision by activating residual visual functions by training light detection and discrimination of visual stimuli. This review discusses the rationale underlying these paradigms and summarizes the available evidence with respect to treatment efficacy. The issues raised in our review should help guide clinical care and stimulate new ideas for future research uncovering the underlying neural correlates of the different treatment paradigms. We propose that both local within-system interactions (i.e., relying on plasticity within peri-lesional spared tissue and changes in more global between-system networks (i.e., recruiting alternative visual pathways contribute to both vision restoration and compensatory rehabilitation that ultimately have implications for the rehabilitation of cognitive functions.

Osteoporosis in laying hens has been a production and welfare concern for several decades. The objective of this study was to determine whether differing opportunities for exercise during pullet rearing influences long-term bone quality characteristics in end-of-lay hens. A secondary objective was to assess whether differing opportunities for exercise in adult housing systems alters bone quality characteristics in end-of-lay hens. Four flock replicates of 588 Lohmann Selected Leghorn-Lite pullets were reared in either conventional cages (Conv) or an aviary rearing system (Avi) and placed into conventional cages (CC), 30-bird furnished cages (FC-S), or 60-bird furnished cages (FC-L) for adult housing. Wing and leg bones were collected at the end-of-lay to quantify bone composition and strength using quantitative computed tomography and bone breaking strength (BBS). At the end-of-lay, Avi hens had greater total and cortical cross-sectional area (P lay. © The Author 2017. Published by Oxford University Press on behalf of Poultry Science Association.

Vemula, Rahul; Greco, Gregory

2012-05-01

Branchial cleft cysts are congenital anomalies that arise from the aberrant embryological development of the branchial apparatus. The location of a branchial cleft cyst is determined by which branchial cleft failed to obliterate during embryological development, with the second branchial cleft cyst being the most commonly recognized lesion. Although the most common location for branchial cleft cysts is between the external auditory canal and the level of the clavicle, the literature does describe unusual locations. We present a case a 15-year-old boy who had an enlarging lesion on his back that had been present since birth. A presumptive radiologic diagnosis of lymphangioma circumscriptum was made. Upon excision of the lesion and pathologic examination, it was determined to be a branchial cleft cyst. The patient had an uneventful postoperative course, and no recurrence was noted after a 2-year follow-up. Our clinical report demonstrates a lesion on the posterior thorax that proved to be a branchial cleft cyst and should always be part of the differential diagnosis for soft tissue masses of the thorax.

The first nuclear power plant was nearing completion. However, due to change in political climate and support for the nuclear power program, this has been mothballed. There is a possibility for the introduction of nuclear power plant in the country's projected energy sources by the year 2020. The country has one research reactor, but at the present time it is undergoing repair and is not operational. The Philippine Nuclear Research Institute (PNRI), an Institute under the Department of Science and Technology (DOST), is the sole government agency mandated by the law to take charge of all matters pertaining to nuclear science and technology, and the regulation of nuclear energy. There is one another government agency, the Radiation Health Service (RHS) of the Department of Health, which is responsible for regulating the use and application of X-rays and non-ionizing radiation. The PNRI conducts national training courses in nuclear science and technology, and radiation protection to users of radioisotopes. Individual courses are outlined in the paper. Up to the present time, around 7,300 have participated in national training courses conducted by PNRI. Distributions of PNRI trainees are: 53 % for industrial, 12 % medical, 12 % for academe, and 23 % for others. Nuclear science and technology education in schools and universities are presented. The International Atomic Energy Agency (IAEA) training activities availed 77 % of the total foreign training from 1993 to 1998; Japan follows next at 20 %; and others comprise the remaining 3 %. An approach to training and human resources development, which could reach out to more target trainees, is Distance Learning.

Sex development depends on the synchronous interaction of complicated genetic and hormonal events. Sex differentiation begins with sex determination, which is the assignment of the embryonic bipotential gonads as either testes or ovaries on the basis of transcriptional regulation. Hormonal regulation then directs the development of the male or female phenotype. Disruptions of this intricate cascade of events result in disorders of sexual development. A 16-year-old female adolescent presented with primary amenorrhea. Evaluation revealed female external genitalia, XY karyotype, absent gonadal tissue, and rudimentary Müllerian structures. On the basis of her constellation of findings, the most logical diagnosis was the rare embryonic testicular regression syndrome. A careful understanding of embryonic sexual development is critical to the evaluation of patients with disorders of sexual development.

2003-04-01

For decades, the understanding of craniofacial development has been a central issue in odontology and developmental biology. As a consequence, a significant number of deformities are being studied for their variety of genotype and phenotype. Although there is little doubt about the essential roles of homeobox genes, transcription factors, and growth factors, we now know at least the fundamental strategy of craniofacial biology. The tooth as an organ performs a whole range of functions, each of which is truly indispensable for the maintenance of life. The possession of teeth is, therefore, obviously coupled with the complication of the natural structure of an individual organism. In the following, we shall focus on a brief history of tooth studies and some suggestions for obtaining a full understanding of teeth in the future. Copyright 2003 Wiley-Liss, Inc.

While presenting two programmes which respectively concern the management of surroundings and resources, and the fields of energy and of sustainable development and land planning, and commenting their financial means, their objectives and performance indicators, this report shows that these programmes are facing insufficient grants. Then, it shows that the different public operators (research laboratories, centres and institutions, public agencies) are weakened by decreasing allocations. Three examples are then studied to show the difficulties of these institutions which have to perform fundamental missions with limited means: IFREMER (in the case of oyster control), INRA (for the development of the biotechnology sector) and IRSN (for the safety of nuclear waste storage)

Stagnating liquid biofuel developments in Russia: Present status andfuture perspectives

International Nuclear Information System (INIS)

Pristupa, Alexey O.; Mol, Arthur P.J.; Oosterveer, Peter

2010-01-01

It is widely acknowledged that Russia possesses enormous biomass resources (). Its vast areas devoted to agricultural production and plentiful timber resources suggest good prospects for the development of liquid biofuel production. However, no significant advances in this direction have been reported till now. None of the numerous investment projects announced at the heydays of biofuel excitement in Russia (2006-2008) are at the moment commercially operating. There are no specialised plants for the production of bioethanol and biodiesel in Russia. Little is known of the reasons for this discrepancy between biofuel potential and actual development. In investigating this discrepancy, this article analyses national developments and investigates local dynamics through a case-study in the Omsk region. It is found that the reasons for this discrepancy are not related to technological incapabilities, but are to be found in the low policy and institutional priority given to non-fossil fuel exploitation and lack of market opportunities. Sprouts of second generation liquid biofuel technologies can be identified within the state system, but it remains to be seen how strong and how long these will be supported by the Russian state.

Stellar Presentations (Abstract)

(Abstract only) The AAVSO is in the process of expanding its education, outreach and speakers bureau program. powerpoint presentations prepared for specific target audiences such as AAVSO members, educators, students, the general public, and Science Olympiad teams, coaches, event supervisors, and state directors will be available online for members to use. The presentations range from specific and general content relating to stellar evolution and variable stars to specific activities for a workshop environment. A presentation—even with a general topic—that works for high school students will not work for educators, Science Olympiad teams, or the general public. Each audience is unique and requires a different approach. The current environment necessitates presentations that are captivating for a younger generation that is embedded in a highly visual and sound-bite world of social media, twitter and U-Tube, and mobile devices. For educators, presentations and workshops for themselves and their students must support the Next Generation Science Standards (NGSS), the Common Core Content Standards, and the Science Technology, Engineering and Mathematics (STEM) initiative. Current best practices for developing relevant and engaging powerpoint presentations to deliver information to a variety of targeted audiences will be presented along with several examples.

Enhanced Cognitive Walkthrough: Development of the Cognitive Walkthrough Method to Better Predict, Identify, and Present Usability Problems

Directory of Open Access Journals (Sweden)

Lars-Ola Bligård

2013-01-01

Full Text Available To avoid use errors when handling medical equipment, it is important to develop products with a high degree of usability. This can be achieved by performing usability evaluations in the product development process to detect and mitigate potential usability problems. A commonly used method is cognitive walkthrough (CW, but this method shows three weaknesses: poor high-level perspective, insufficient categorisation of detected usability problems, and difficulties in overviewing the analytical results. This paper presents a further development of CW with the aim of overcoming its weaknesses. The new method is called enhanced cognitive walkthrough (ECW. ECW is a proactive analytical method for analysis of potential usability problems. The ECW method has been employed to evaluate user interface designs of medical equipment such as home-care ventilators, infusion pumps, dialysis machines, and insulin pumps. The method has proved capable of identifying several potential use problems in designs.

Peng Shilu

1987-01-01

Energy resource is an essential prerequisite for realizing the strategic objectives of the national economic development in China. By the end of this century the objectives of the national economic development are as follows: the national annual gross value of industrial and agricultural output will be quadrupled as that in 1980; the annual average revenue per capita is expected to be 800-1000 U.S. dollars. For realizing these objectives, a significant discrepancy is anticipated between the energy demand and energy supplied. It is concluded, therefore, that the utilization of nuclear power should be regarded as one of the components constituting China's energy resources. From a longterm point of view, nuclear power will play an even more important role with each passing day. (author)

Present status of uranium-plutonium mixed carbide fuel development for LMFBRs

International Nuclear Information System (INIS)

Handa, Muneo; Suzuki, Yasufumi

1984-01-01

The feature of carbide fuel is that it has the doubling time as short as about 13 years, that is, close to one half as compared with oxide fuel. The development of the carbide fuel in the past 10 years has been started in amazement. Especially in the program of new fuel development in USA started in 1974, He and Na bond fuel attained the burnup of 16 a/o without causing the breaking of cladding tubes. In 1984, the irradiation of the assembly composed of 91 fuel pins in the FFTF is expected. On the other hand in Japan, the fuel research laboratory was constructed in 1974 in the Oarai Laboratory, Japan Atomic Energy Research Institute, to carry out the studies on carbide fuel. In the autumn of 1982, two carbide fuel pins with different chemical composition have been successfully made. Accordingly, the recent status of the development is explained. The uranium-plutonium mixed carbide fuel is suitable to liquid metal-cooled fast breeder reactors because of large heat conductivity and the high density of nuclear fission substances. The thermal and nuclear characteristics of carbide fuel, the features of the reactor core using carbide fuel, the chemical and mechanical interaction of fuel and cladding tubes, the selection of bond materials, the manufacturing techniques for the fuel, the development of the analysis code for fuel behavior, and the research and development of carbide fuel in Japan are described.

A Database of Historical Information on Landslides and Floods in Italy

Science.gov (United States)

Guzzetti, F.; Tonelli, G.

2003-04-01

For the past 12 years we have maintained and updated a database of historical information on landslides and floods in Italy, known as the National Research Council's AVI (Damaged Urban Areas) Project archive. The database was originally designed to respond to a specific request of the Minister of Civil Protection, and was aimed at helping the regional assessment of landslide and flood risk in Italy. The database was first constructed in 1991-92 to cover the period 1917 to 1990. Information of damaging landslide and flood event was collected by searching archives, by screening thousands of newspaper issues, by reviewing the existing technical and scientific literature on landslides and floods in Italy, and by interviewing landslide and flood experts. The database was then updated chiefly through the analysis of hundreds of newspaper articles, and it now covers systematically the period 1900 to 1998, and non-systematically the periods 1900 to 1916 and 1999 to 2002. Non systematic information on landslide and flood events older than 20th century is also present in the database. The database currently contains information on more than 32,000 landslide events occurred at more than 25,700 sites, and on more than 28,800 flood events occurred at more than 15,600 sites. After a brief outline of the history and evolution of the AVI Project archive, we present and discuss: (a) the present structure of the database, including the hardware and software solutions adopted to maintain, manage, use and disseminate the information stored in the database, (b) the type and amount of information stored in the database, including an estimate of its completeness, and (c) examples of recent applications of the database, including a web-based GIS systems to show the location of sites historically affected by landslides and floods, and an estimate of geo-hydrological (i.e., landslide and flood) risk in Italy based on the available historical information.

Presentation Technique

International Nuclear Information System (INIS)

Froejmark, M.

1992-10-01

The report presents a wide, easily understandable description of presentation technique and man-machine communication. General fundamentals for the man-machine interface are illustrated, and the factors that affect the interface are described. A model is presented for describing the operators work situation, based on three different levels in the operators behaviour. The operator reacts routinely in the face of simple, known problems, and reacts in accordance with predetermined plans in the face of more complex, recognizable problems. Deep fundamental knowledge is necessary for truly complex questions. Today's technical status and future development have been studied. In the future, the operator interface will be based on standard software. Functions such as zooming, integration of video pictures, and sound reproduction will become common. Video walls may be expected to come into use in situations in which several persons simultaneously need access to the same information. A summary of the fundamental rules for the design of good picture ergonomics and design requirements for control rooms are included in the report. In conclusion, the report describes a presentation technique within the Distribution Automation and Demand Side Management area and analyses the know-how requirements within Vattenfall. If different systems are integrated, such as geographical information systems and operation monitoring systems, strict demands are made on the expertise of the users for achieving a user-friendly technique which is matched to the needs of the human being.

Quality control in diagnostic radiology. Historical development and present status in Europe

International Nuclear Information System (INIS)

Michael Moores, B.

2007-01-01

Complete test of publication follows. Quality control is now an accepted activity within the overall radiation protection framework for diagnostic radiology. Indeed it is now a legal requirement within Member States specified in EC Directives that establish the basic requirements for radiation protection in medicine. This was not always the case and its historical development can be considered in three parts: 1) The development of test procedures and standardisation of practices; 2) Harmonisation of initiatives and the creation of a European dimension in such practices; 3) Its role and function in a changing and evolving technological environment - current status and future needs. The development of tests methods for diagnostic X-ray equipment was initially intimately related to the development of a scientific basis for the X-ray imaging process. Knowledge of the physical basis for image production in film-screen and fluoroscopic processes required the definition and specification and measurement of particular parameters within the image forming chain. The development of test methods and the necessary measuring equipment involved ongoing research and development by physical scientists throughout Europe and North America. However, the many different approaches employed meant that results of measurements could not always be compared. However, once acceptable test methods and equipment had been developed it was possible to standardise practices through the development of test protocols. In 1980 a foundation for collective European actions was established through the EC radiation protection research and development programme. This helped to establish a European wide forum for actions in the field of medical radiation protection including quality control. These initiatives were driven by EC Directives, which were concerned with protection of the worker, general public and patients from medical practices that utilised ionising radiation.

Nuclear energy, today and tomorrow. Present status of development and utilization in Japan 1995

International Nuclear Information System (INIS)

1995-01-01

The world population has exceeded 5 billion, today, and it is estimated to reach 10 billion in the middle of the twenty first century. Because of such rapid increase of population, the world energy consumption is estimated to increase tremendously. Furthermore, there are problems of limited energy resources from oil and coal down, how to respond to environment problems such as global warming, acid rain caused by fossil fuel burning, followed by carbon dioxide discharge. Under such circumstances of global scale problems, the nuclear power generation that is excellent in stable nature of supply, economic advantage, less effect to the environment, supplies about 20 % of the total power generation in the world. In our country, some 30 % of the total power generation relies on the nuclear power, as an indispensable power source. Radiation utilization, together with the nuclear power generation, is an important pillar of development and utilization of nuclear energy, and has penetrated deeply in the life of the people, in the fields of industry, agriculture, medicine and environmental protection, and it is contributing to realize affluent life to a great extent. Thus, expectations to the nuclear energy seem to grow larger and larger in future. The publication introduces present status and future potential of the development and utilization of the nuclear energy in Japan, including the basic idea and concrete plans shown in the Long-Term Program.

Lappin, Graham; Noveck, Robert; Burt, Tal

2015-01-01

Introduction Microdosing is an approach to early drug development where exploratory pharmacokinetic data are acquired in humans using inherently safe sub-pharmacologic doses of drug. The first publication of microdose data was 10 years ago and this review comprehensively explores the microdose concept from conception, over the past decade, up until the current date. Areas covered The authors define and distinguish the concept of microdosing from similar approaches. The authors review the ability of microdosing to provide exploratory pharmacokinetics (concentration-time data) but exclude microdosing using positron emission tomography. The article provides a comprehensive review of data within the peer-reviewed literature as well as the latest applications and a look into the future, towards where microdosing may be headed. Expert opinion Evidence so far suggests that microdosing may be a better predictive tool of human pharmacokinetics than alternative methods and combination with physiologically based modelling may lead to much more reliable predictions in the future. The concept has also been applied to drug-drug interactions, polymorphism and assessing drug concentrations over time at its site of action. Microdosing may yet have more to offer in unanticipated directions and provide benefits that have not been fully realised to date. PMID:23550938

This article presents a survey that has been led to study the acceptability of wind turbines by local populations. 11 families living in the neighbourhood of the Salleles wind farm (near Carcassonne, France) have been interviewed. A few recommendations can be drawn from this survey. It is necessary to organize information campaigns in order to make people consider wind farms as elements of the local economy. As for site choice any already visually polluted area should be barred, for wind turbines might be seen more as a supplementary negative element than as a positive element aimed at counterbalancing a dissatisfying situation.

Presenting quantitative information about decision outcomes: a risk communication primer for patient decision aid developers

Science.gov (United States)

2013-01-01

Background Making evidence-based decisions often requires comparison of two or more options. Research-based evidence may exist which quantifies how likely the outcomes are for each option. Understanding these numeric estimates improves patients’ risk perception and leads to better informed decision making. This paper summarises current “best practices” in communication of evidence-based numeric outcomes for developers of patient decision aids (PtDAs) and other health communication tools. Method An expert consensus group of fourteen researchers from North America, Europe, and Australasia identified eleven main issues in risk communication. Two experts for each issue wrote a “state of the art” summary of best evidence, drawing on the PtDA, health, psychological, and broader scientific literature. In addition, commonly used terms were defined and a set of guiding principles and key messages derived from the results. Results The eleven key components of risk communication were: 1) Presenting the chance an event will occur; 2) Presenting changes in numeric outcomes; 3) Outcome estimates for test and screening decisions; 4) Numeric estimates in context and with evaluative labels; 5) Conveying uncertainty; 6) Visual formats; 7) Tailoring estimates; 8) Formats for understanding outcomes over time; 9) Narrative methods for conveying the chance of an event; 10) Important skills for understanding numerical estimates; and 11) Interactive web-based formats. Guiding principles from the evidence summaries advise that risk communication formats should reflect the task required of the user, should always define a relevant reference class (i.e., denominator) over time, should aim to use a consistent format throughout documents, should avoid “1 in x” formats and variable denominators, consider the magnitude of numbers used and the possibility of format bias, and should take into account the numeracy and graph literacy of the audience.

We will present our last development of GMR-based magnetic sensors devoted to sensing application for non-destructive control application. In these first realizations, we have chosen a so-called shape anisotropy - exchange biased strategy to fulfill the field-sensing criteria in the μT range in devices made of micronic single elements. Our devices realized by optical lithography, and whose typical sizes range from 150 μm x 150 μm to 500 μm x 500 μm elements, are made of trilayers GMR-based technology and consist of several circuitries of GMR elements of different lengths, widths and gaps. To obtain a full sensing linearity and reversibility requiring a perpendicular magnetic arrangement between both sensitive and hard layer, the magnetization of the latter have been hardened by pinning it with an antiferromagnetic material. The specific geometry of the design have been engineered in order to optimize the magnetic response of the soft layer via the different magnetic torques exerted on it essentially played by the dipolar fields or shape anisotropy, and the external magnetic field to detect. The smaller dimensions in width and in gap are then respectively of 2 μm and 3 μm to benefit of the full shape anisotropy formatting the magnetic response.

[The historical background and present development of evidence-based healthcare and clinical nursing].

Evidence-based healthcare (EBHC) emphasizes the integration of the best research evidence with patient values, specialist suggestions, and clinical circumstances during the process of clinical decision-making. EBHC is a recognized core competency in modern healthcare. Nursing is a professional discipline of empirical science that thrives in an environment marked by advances in knowledge and technology in medicine as well as in nursing. Clinical nurses must elevate their skills and professional qualifications, provide efficient and quality health services, and promote their proficiency in EBHC. The Institute of Medicine in the United States indicates that evidence-based research results often fail to disseminate efficiently to clinical decision makers. This problem highlights the importance of better promoting the evidence-based healthcare fundamentals and competencies to frontline clinical nurses. This article describes the historical background and present development of evidence-based healthcare from the perspective of modern clinical nursing in light of the importance of evidence-based healthcare in clinical nursing; describes the factors associated with evidence-based healthcare promotion; and suggests strategies and policies that may improve the promotion and application of EBHC in clinical settings. The authors hope that this paper provides a reference for efforts to improve clinical nursing in the realms of EBHC training, promotion, and application.

Full Text Available O objetivo deste artigo é a aplicação da técnica de Pesquisa Operacional Análise Envoltória de Dados - DEA, por meio do índice composto das fronteiras clássica e invertida, para avaliar o custo/beneficio de aeronaves de transporte civil. Para tal, foram adotados como inputs: a preço de mercado, e b custos operacionais; e como outputs: a peso de carga paga, b velocidade de cruzeiro, e c razão máxima de subida com um único motor. Para garantir a homogeneidade das DMUs, os aviões foram divididos segundo o sistema de propulsão e segundo as categorias: regional, narrow-body e wide-body. Foram também agrupados em diferentes alcances, para que se pudessem identificar os aviões com melhor custo/beneficio em cada um. Os resultados encontrados permitem afirmar que os aviões com o melhor custo/beneficio são os que já tiveram sua produção descontinuada, mas que ainda não estão muito defasados tecnologicamente.The objective of this paper was to apply the operational research technique of Data Envelopment Analysis (DEA, through the composite index of classic and inverted borders, to evaluate the cost-benefit of civil transport aircrafts. To this end, a market price, and b operating costs were used as inputs; and, a payload, b cruise speed, and c maximum reason climb with one engine were used as outputs. To ensure homogeneity of DMUs, the planes were divided according to the propulsion system and in the following categories: regional, narrow-body and wide-body; they were also grouped into different ranges, so that the best cost-benefit for each aircraft could be identified. Results allowed for the following conclusion: the best cost-benefits were found in planes where the production had already been discontinued, but they were not very technologically outdated yet.

In this study, the effect of random vs. site-directed immobilization techniques on the performance of antibody-based HPLC columns was investigated using a single-domain camelid antibody (VHH) directed against methotrexate (MTX) as a model system. First, the high flow-through support material POROS-OH was activated with disuccinimidyl carbonate (DSC), and the VHH was bound in a random manner via amines located on the protein's surface. The resulting column was characterized by Frontal Affinity Chromatography (FAC). Then, two site-directed techniques were explored to increase column efficiency by immobilizing the antibody via its C-terminus, i.e., away from the antigen-binding site. In one approach, a tetra-lysine tail was added, and the antibody was immobilized onto DSC-activated POROS. In the second site-directed approach, the VHH was modified with the AviTag peptide, and a biotin-residue was enzymatically incorporated at the C-terminus using the biotin ligase BirA. The biotinylated antibody was subsequently immobilized onto NeutrAvidin-derivatized POROS. A comparison of the FAC analyses, which for all three columns showed excellent linearity (R(2)>0.999), revealed that both site-directed approaches yield better results than the random immobilization; the by far highest efficiency, however, was determined for the immunoaffinity column based on AviTag-biotinylated antibody. As proof of concept, all three columns were evaluated for quantification of MTX dissolved in phosphate buffered saline (PBS). Validation using UV-detection showed excellent linearity in the range of 0.04-12μM (R(2)>0.993). The lower limit of detection (LOD) and lower limit of quantification (LLOQ) were found to be independent of the immobilization strategy and were 40nM and 132nM, respectively. The intra- and inter-day precision was below 11.6%, and accuracy was between 90.7% and 112%. To the best of our knowledge, this is the first report of the AviTag-system in chromatography, and the first

1979-01-01

The Japanese steel industry consumes about 18% of total energy consumption in Japan, and 56 million tons of coking coal were imported in 1977 at the cost of approximately $3.3 billion. Securing of required quantity of coking coal, price negotiation, the transport and storage of coal, and environmental pollution are the problems concerning the steel industry. In order to solve these problems, the introduction of atomic energy to steel-making is considered. The use of high temperature gas-cooled reactors is capable of supplying large quantities of heat and electric power which are required for steel-making. The Committee on Utilization of Nuclear Energy, the Iron and Steel Institute of Japan, was established in 1968, and the research and development of nuclear steel-making were started as a national project in 1973. The outline of nuclear steel-making system is explained. The Japan Atomic Energy Research Institute is promoting the research and development on a multi-purpose HTGR with 1000 deg C outlet helium temperature. The research and development in progress now are as follows: high temperature heat exchangers, heat resistant superalloys, high temperature heat insulating materials, reducing gas-producing unit, reduced iron-producing system, and the total system for nuclear steel-making.

In the last two decades the definition of the term "virtual museum" changed due to rapid technological developments. Using today's available 3D technologies a virtual museum is no longer just a presentation of collections on the Internet or a virtual tour of an exhibition using panoramic photography. On one hand, a virtual museum should enhance a museum visitor's experience by providing access to additional materials for review and knowledge deepening either before or after the real visit. On the other hand, a virtual museum should also be used as teaching material in the context of museum education. The laboratory for Photogrammetry & Laser Scanning of the HafenCity University Hamburg has developed a virtual museum (VM) of the museum "Alt-Segeberger Bürgerhaus", a historic town house. The VM offers two options for visitors wishing to explore the museum without travelling to the city of Bad Segeberg, Schleswig-Holstein, Germany. Option a, an interactive computer-based, tour for visitors to explore the exhibition and to collect information of interest or option b, to immerse into virtual reality in 3D with the HTC Vive Virtual Reality System.

The wide spread of digital technology in the medical field has led to a demand for the high-quality, high-speed, and user-friendly digital image presentation system in the daily medical conferences. To fulfill this demand, we developed a presentation system for radiological and pathological images. It is composed of a super-high-definition (SHD) imaging system, a radiological image database (R-DB), a pathological image database (P-DB), and the network interconnecting these three. The R-DB consists of a 270GB RAID, a database server workstation, and a film digitizer. The P-DB includes an optical microscope, a four-million-pixel digital camera, a 90GB RAID, and a database server workstation. A 100Mbps Ethernet LAN interconnects all the sub-systems. The Web-based system operation software was developed for easy operation. We installed the whole system in NTT East Kanto Hospital to evaluate it in the weekly case conferences. The SHD system could display digital full-color images of 2048 x 2048 pixels on a 28-inch CRT monitor. The doctors evaluated the image quality and size, and found them applicable to the actual medical diagnosis. They also appreciated short image switching time that contributed to smooth presentation. Thus, we confirmed that its characteristics met the requirements.

The primary purpose of this study was to determine the effectiveness of implementing desktop 3-dimensional (3D) stereo images of human anatomy into an undergraduate human anatomy distance laboratory. User perceptions of 2D and 3D images were gathered via questionnaire in order to determine ease of use and level of satisfaction associated with the 3D software in the online learning environment. Mayer's (2001, p. 184) principles of design were used to develop the study materials that consisted of PowerPoint presentations and AVI files accessed via Blackboard. The research design employed a mixed-methods approach. Volunteers each were administered a demographic survey and were then stratified into groups based upon pre-test scores. A total sample size of 62 pairs was available for combined data analysis. Quantitative research questions regarding the effectiveness of 2D versus the 3D treatment were analyzed using a doubly-multivariate repeated measures (Doubly-MANOVA) design. Paired test scores achieved by undergraduates on a laboratory practical of identification and spatial relationships of the bones and features of a human skull were used in the analysis. The questionnaire designed to gather user perceptions consisted of quantitative and qualitative questions. Response frequencies were analyzed for the two groups and common themes were noted. Results revealed a statistically significant difference in group means for the main effect of the treatment groups 2D and 3D and for the variables of identification and relationship with the 3D group outperforming the 2D group on both dependent variables. Effect sizes were determined to be small, 0.215 for the identification variable and 0.359 for the relationship variable. Overall, all students liked the convenience of using PowerPoint and AVI files online. The 3D group felt their PowerPoint was more realistic than did the 2D group and both groups appreciated the detailed labeling of the online images. One third of the

Molecular markers associated with gene coding regions are useful tools for bridging functional and structural genomics. Due to their high abundance in plant genomes, single nucleotide polymorphisms (SNPs) are present within virtually all genomic regions, including most coding sequences. The objective of this study was to develop a set of SNPs for the apple by taking advantage of the wealth of genomics resources available for the apple, including a large collection of expressed sequenced tags (ESTs). Using bioinformatics tools, a search for SNPs within an EST database of approximately 350,000 sequences developed from a variety of apple accessions was conducted. This resulted in the identification of a total of 71,482 putative SNPs. As the apple genome is reported to be an ancient polyploid, attempts were made to verify whether those SNPs detected in silico were attributable either to allelic polymorphisms or to gene duplication or paralogous or homeologous sequence variations. To this end, a set of 464 PCR primer pairs was designed, PCR was amplified using two subsets of plants, and the PCR products were sequenced. The SNPs retrieved from these sequences were then mapped onto apple genetic maps, including a newly constructed map of a Royal Gala x A689-24 cross and a Malling 9 x Robusta 5, map using a bin mapping strategy. The SNP genotyping was performed using the high-resolution melting (HRM) technique. A total of 93 new markers containing 210 coding SNPs were successfully mapped. This new set of SNP markers for the apple offers new opportunities for understanding the genetic control of important horticultural traits using quantitative trait loci (QTL) or linkage disequilibrium analysis. These also serve as useful markers for aligning physical and genetic maps, and as potential transferable markers across the Rosaceae family.

Present state of research and development of MHD power generation

International Nuclear Information System (INIS)

Ikeda, Shigeru

1978-01-01

MHD power generation can obtain electric energy directly from the heat energy of high speed plasma flow, and the power generating plant of 1 million kW can be realized by this method. When the MHD power generation method is combined before conventional thermal power generation method, the thermal efficiency can be raised to about 60% as compared with 38% in thermal power generation plants. The research and development of MHD power generation are in progress in USA and USSR. The research and development in Japan are in the second stage now after the first stage project for 10 years, and the Mark 7 generator with 100 kW electric output for 200 hr continuous operation is under construction. The MHD power generation is divided into three types according to the conductive fluids used, namely combustion type for thermal power generation, unequilibrated type and liquid metal type for nuclear power generation. The principle of MHD power generation and the constitution of the plant are explained. In Japan, the Mark 2 generator generated 1,180 kW for 1 min in 1971, and the Mark 3 generator generated 1.9 kW continuously for 110 hr in 1967. The MHD generator with superconducting magnet succeeded in 1969 to generate 25 kW for 6 min. The second stage project aimes at collecting design data and obtaining operational experience for the construction of 10 MW class pilot plant, and the Mark 7 and 8 generators are planned. (Kako, I.)

Vitamin D assays: past and present debates, difficulties, and developments.

Fraser, William D; Milan, Anna M

2013-02-01

Clinical interest in Vitamin D and its purported roles not only in calcium and bone metabolism but in several other medical conditions (diabetes, cardiovascular disease, multiple sclerosis, cancer, psychiatric disorders, neuro-muscular disease) has led to a surge in laboratory requests for 25 hydroxy vitamin D and 1,25 dihydroxy vitamin D measurement. Circulating 25 hydroxy vitamin D concentration is routinely used as the best indicator of vitamin D status, but measurement of other metabolites, especially the physiologically active 1,25 dihyroxy vitamin D, are of clinical value. Over the last 40 years the development of assays for vitamin D and its metabolites from early competitive binding assays through to immunoassay and liquid chromatography aligned to mass spectrometry have demonstrated various analytical challenges, the advantages and disadvantages of each method are constantly changing with new technological developments. Immunoassay remains the predominant mode of measurement for 25-hydroxy vitamin D although problems with equimolar recovery of the D2 and D3 metabolites remain an issue. Standardisation of all assays has been improved but not resolved with the currently available reference materials as evidenced by the international vitamin D external quality assurance scheme, DEQAS. The choice of method for each laboratory remains a balance mainly between turn around time, convenience, cost and the specificity and accuracy of the information obtained. With increasing discussion and clinical interest surrounding other vitamin D metabolites the vitamin D assay debate is set to continue.

Biosynthesis of Oxytetracycline by Streptomyces rimosus: Past, Present and Future Directions in the Development of Tetracycline Antibiotics

Directory of Open Access Journals (Sweden)

Hrvoje Petković

2017-01-01

Full Text Available Natural tetracycline (TC antibiotics were the first major class of therapeutics to earn the distinction of ‘broad-spectrum antibiotics’ and they have been used since the 1940s against a wide range of both Gram-positive and Gram-negative pathogens, mycoplasmas, intracellular chlamydiae, rickett siae and protozoan parasites. The second generation of semisynthetic tetracyclines, such as minocycline and doxycycline, with improved antimicrobial potency, were introduced during the 1960s. Despite emerging resistance to TCs erupting during the 1980s, it was not until 2006, more than four decades later, that a third-generation TC, named tigecycline, was launched. In addition, two TC analogues, omadacycline and eravacycline, developed via (semisynthetic and fully synthetic routes, respectively, are at present under clinical evaluation. Interestingly, despite very productive early work on the isolation of a Streptomyces aureofaciens mutant strain that produced 6-demethyl-7-chlortetracycline, the key intermediate in the production of second- and third-generation TCs, biosynthetic approaches in TC development have not been productive for more than 50 years. Relatively slow and tedious molecular biology approaches for the genetic manipulation of TC-producing actinobacteria, as well as an insufficient understanding of the enzymatic mechanisms involved in TC biosynthesis have significantly contributed to the low success of such biosynthetic engineering efforts. However, new opportunities in TC drug development have arisen thanks to a signifi cant progress in the development of affordable and versatile biosynthetic engineering and synthetic biology approaches, and, importantly, to a much deeper understanding of TC biosynthesis, mostly gained over the last two decades.

Full Text Available Nowadays, the market of medical tourism is considered as a revenue and competitive industry throughout the world, it is also regarded as a novel field of the sophisticated tourism. Therefore, most of the developing countries have focused on the medical tourism industry and they are planning for it. In 2016, the present research was conducted with the main objective of devising a pattern for medical tourism development in the West Azerbaijan Province. The statistical population consisted of all medical tourists who referred to the hospitals located in the province. With regard to the krejcie-morgan table and statistical population, the number of the sample was estimated to be equal to 260 persons. These persons were selected based on the multi-stage sampling method. The scholar made questionnaire and studies of the Ricafort and Kazemi were employed as the instrument of collecting data. The validity of questionnaire was confirmed by the experts, professors, supervising and advising professors after applying the required amendments. The reliability was realized using factor analysis method. The PLS method was utilized for analysis of the data. The findings indicate that %82.5 of the variations linked to the medical tourism development has been realized via changes in the two predictor variables (independent variable, including hospital selection and West Azerbaijan selection. Moreover, the two main factors, including hospital selection and West Azerbaijan selection with impact factors of 0.486 and 0.469, respectively have a direct and significant impact on the development of medical tourism of the province. West Azerbaijan Province has so many potentials, and due to this fact there exist very special conditions which can contribute to the development of the medical tourism industry in this region. It can be deduced that by carrying out measures, like creating a brand for province in the medical tourism field, coordination of the corresponding

Three-day dendritic cells for vaccine development: Antigen uptake, processing and presentation

Directory of Open Access Journals (Sweden)

Schendel Dolores J

2010-09-01

Full Text Available Abstract Background Antigen-loaded dendritic cells (DC are capable of priming naïve T cells and therefore represent an attractive adjuvant for vaccine development in anti-tumor immunotherapy. Numerous protocols have been described to date using different maturation cocktails and time periods for the induction of mature DC (mDC in vitro. For clinical application, the use of mDC that can be generated in only three days saves on the costs of cytokines needed for large scale vaccine cell production and provides a method to produce cells within a standard work-week schedule in a GMP facility. Methods In this study, we addressed the properties of antigen uptake, processing and presentation by monocyte-derived DC prepared in three days (3d mDC compared with conventional DC prepared in seven days (7d mDC, which represent the most common form of DC used for vaccines to date. Results Although they showed a reduced capacity for spontaneous antigen uptake, 3d mDC displayed higher capacity for stimulation of T cells after loading with an extended synthetic peptide that requires processing for MHC binding, indicating they were more efficient at antigen processing than 7d DC. We found, however, that 3d DC were less efficient at expressing protein after introduction of in vitro transcribed (ivtRNA by electroporation, based on published procedures. This deficit was overcome by altering electroporation parameters, which led to improved protein expression and capacity for T cell stimulation using low amounts of ivtRNA. Conclusions This new procedure allows 3d mDC to replace 7d mDC for use in DC-based vaccines that utilize long peptides, proteins or ivtRNA as sources of specific antigen.

Present status of uranium-plutonium mixed carbide fuel development for LMFBR

International Nuclear Information System (INIS)

Handa, Muneo; Suzuki, Yasufumi.

One Oarai characteristic of a carbide fuel is that its doubling time is about 13 years which is only about half as long as that of an oxide fuel. The development of carbide fuels in the past ten years has been truly remarkable. Especially, through the new fuel development program initiated in 1974 in the United States, success has been achieved with respect to He- and Na-bond fuels in obtaining a 16 a/o burning rate without damage to cladding tubes. In 1984 at FFTF, a radiation of a fuel assembly consisting 91 fuel pins is contemplated. On the other hand, in Japan, in 1974, a Fuel Research Wing specializing in the study of carbide fuels was constructed in the Oarai Laboratory of the Atomic Energy Research Institute and in the fall of 1982, was successful in fabricating two carbide fuel pins having different chemical compositions

Methodological developments in searching for studies for systematic reviews: past, present and future?

Lefebvre, Carol; Glanville, Julie; Wieland, L Susan; Coles, Bernadette; Weightman, Alison L

2013-09-25

The Cochrane Collaboration was established in 1993, following the opening of the UK Cochrane Centre in 1992, at a time when searching for studies for inclusion in systematic reviews was not well-developed. Review authors largely conducted their own searches or depended on medical librarians, who often possessed limited awareness and experience of systematic reviews. Guidance on the conduct and reporting of searches was limited. When work began to identify reports of randomized controlled trials (RCTs) for inclusion in Cochrane Reviews in 1992, there were only approximately 20,000 reports indexed as RCTs in MEDLINE and none indexed as RCTs in Embase. No search filters had been developed with the aim of identifying all RCTs in MEDLINE or other major databases. This presented The Cochrane Collaboration with a considerable challenge in identifying relevant studies.Over time, the number of studies indexed as RCTs in the major databases has grown considerably and the Cochrane Central Register of Controlled Trials (CENTRAL) has become the best single source of published controlled trials, with approximately 700,000 records, including records identified by the Collaboration from Embase and MEDLINE. Search filters for various study types, including systematic reviews and the Cochrane Highly Sensitive Search Strategies for RCTs, have been developed. There have been considerable advances in the evidence base for methodological aspects of information retrieval. The Cochrane Handbook for Systematic Reviews of Interventions now provides detailed guidance on the conduct and reporting of searches. Initiatives across The Cochrane Collaboration to improve the quality inter alia of information retrieval include: the recently introduced Methodological Expectations for Cochrane Intervention Reviews (MECIR) programme, which stipulates 'mandatory' and 'highly desirable' standards for various aspects of review conduct and reporting including searching, the development of Standard Training

BATAN, started out as a governmental committee established in 1954, has a new organizational structure, based on Presidential Decree of 1998. BATAN has developed its researches in almost practically all-nuclear fields. The situation in Indonesia has been much influenced by the economic crisis, which still being faced by Indonesia. BATAN's strategic planning is described in four areas, those are: 1. Basic human needs, 2. Energy, natural resources and environment, 3. Industry, 4. Socio-cultural and institution. Priority has been given to fulfill, as well as to promote agriculture, health and the industry related to people's welfare, which may develop and improve the immediate needs of the people. In the meantime, we have made considerable investments in manpower development in anticipation of the introduction of nuclear power. BATAN, as of September 1999, has 3889 employees, 26 % of them have bachelor degree, 6 % hold master degrees, and only 2% hold doctoral degree, a total of 34 % employees with university education. Others 11 % have either non-vocational or vocational education beyond High School. The rest of 55 % have high school education or lower, they are administrative clerks (25 %) or technicians (30 %). In the human resources development, BATAN's Education and Training Center, in collaboration with some universities and other national/international institutions, is managing education and training programs for employees. To date, there are 43 BATAN employees studying in various universities in Japan, while another 42 employees are studying in six different countries. Research and Development that have more direct impact to the community will become a priority in the coming years. Without undermining the importance of basic research in advanced fields, we will expect to have more research on application to optimize utilization of research reactors and related facilities for the benefit of both the energy and non-energy sectors.

Teratology - past, present and future.

2012-12-01

Teratology is the science that studies the causes, mechanisms, and patterns of abnormal development. The authors present an updated overview of the most important milestones and stages of the development of modern teratology. Development of knowledge and society led to the recognition that causes of congenital developmental disorders (CDDs) might be caused by various mechanical effects, foetal diseases, and retarded or arrested development of the embryo and foetus. Based on the analysis of the historical development of hypotheses and theories representing a decisive contribution to this field, we present a survey of the six Wilson's fundamental principles of teratology. The aim of observing these principles is to get insight into developmental relations and to understand mechanisms of action on the level of cell populations (elementary morphogenetic processes), tissues and organs. It is important to realise that any negative intervention into the normal course of these processes, either on genetic or non-genetic basis, inevitably leads to a sequence of subsequent changes resulting in CDDs. Moreover, the classical toxicologic monotonic dose-response paradigm recently has been challenged by the so-called "low dose-hypothesis", particularly in the case of endocrine active substances. These include some pesticides, dioxins, polychlorobiphenyls (PCBs), and bisphenol A. Despite modern approaches of molecular biology and genetics, along with top diagnostic techniques, we are still not able to identify the actual cause in more than 65 to 70% of all congenital defects classified as having an unknown etiology. Today CDDs include any birth defect, either morphological, biochemical, or behavioural.

ABSTRACT Although the New York/New Jersey (NY/NJ) area is an epicenter for carbapenem-resistant Enterobacteriaceae (CRE), there are few multicenter studies of CRE from this region. We characterized patients with CRE bacteremia in 2013 at eight NY/NJ medical centers and determined the prevalence of carbapenem resistance among Enterobacteriaceae bloodstream isolates and CRE resistance mechanisms, genetic backgrounds, capsular types (cps), and antimicrobial susceptibilities. Of 121 patients with CRE bacteremia, 50% had cancer or had undergone transplantation. The prevalences of carbapenem resistance among Klebsiella pneumoniae, Enterobacter spp., and Escherichia coli bacteremias were 9.7%, 2.2%, and 0.1%, respectively. Ninety percent of CRE were K. pneumoniae and 92% produced K. pneumoniae carbapenemase (KPC-3, 48%; KPC-2, 44%). Two CRE produced NDM-1 and OXA-48 carbapenemases. Sequence type 258 (ST258) predominated among KPC-producing K. pneumoniae (KPC-Kp). The wzi154 allele, corresponding to cps-2, was present in 93% of KPC-3-Kp, whereas KPC-2-Kp had greater cps diversity. Ninety-nine percent of CRE were ceftazidime-avibactam (CAZ-AVI)-susceptible, although 42% of KPC-3-Kp had an CAZ-AVI MIC of ≥4/4 μg/ml. There was a median of 47 h from bacteremia onset until active antimicrobial therapy, 38% of patients had septic shock, and 49% died within 30 days. KPC-3-Kp bacteremia (adjusted odds ratio [aOR], 2.58; P = 0.045), cancer (aOR, 3.61, P = 0.01), and bacteremia onset in the intensive care unit (aOR, 3.79; P = 0.03) were independently associated with mortality. Active empirical therapy and combination therapy were not associated with survival. Despite a decade of experience with CRE, patients with CRE bacteremia have protracted delays in appropriate therapies and high mortality rates, highlighting the need for rapid diagnostics and evaluation of new therapeutics.

Presenting Newtonian gravitation

International Nuclear Information System (INIS)

Counihan, Martin

2007-01-01

The basic principles of the Newtonian theory of gravitation are presented in a way which students may find more logically coherent, mathematically accessible and physically interesting than other approaches. After giving relatively simple derivations of the circular hodograph and the elliptical orbit from the inverse-square law, the concept of gravitational energy is developed from vector calculus. It is argued that the energy density of a gravitational field may reasonably be regarded as -g 2 /8πG, and that the inverse-square law may be replaced by a Schwarzschild-like force law without the need to invoke non-Euclidean geometry

We describe two case reports of immune-suppressed patients receiving oral steroids and who presented lung Strongyloidiasis; later they evolved toward respiratory failure, with different clinical courses. One developed severe hypoxaemia, hemodynamic instability and death. The worst prognosis in this patient was determined by diffuse infiltrates and the resulting lung injury. The other one presented a stable clinical course and evolved to full recovery; this case presented a cavern in the chest X-ray that could represent a preliminary phase for lung extension of the infection. The difference in the evolution of these two patients is determined by the different presentation of the lung damage

The development of all-polymer-based piezoelectrically active photocurable resin for 3D printing process (Conference Presentation)

Science.gov (United States)

Baker, Evan; Chu, Weishen; Ware, Henry Oliver T.; Farsheed, Adam C.; Sun, Cheng

2017-02-01

We present in this work the development and experimental validation of a new piezoelectric material (V-Ink) designed for compatibility with projection stereolithography additive manufacturing techniques. Piezoelectric materials generate a voltage output when a stress is applied to the material, and also can be actuated by using an external voltage and power source. This new material opens up new opportunities for functional devices to be developed and rapidly produced at low cost using emerging 3D printing techniques. The new piezoelectric material was able to generate 115mV under 1N of strain after being polled at 80°C for 40 minutes and the optimal results had a piezoelectric coefficient of 105x10^(-3)V.m/N. The current iteration of the material is a suspension, although further work is ongoing to make the resin a true solution. The nature of the suspension was characterized by a time-lapse monitoring and through viscosity testing. The potential exists to further increase the piezoelectric properties of this material by integrating a mechanical to electrical enhancer such as carbon nanotubes or barium titanate into the material. Such materials need to be functionalized to be integrated within the material, which is currently being explored. Printing with this material on a "continuous SLA" printer that we have developed will reduce build times by an order of magnitude to allow for mass manufacturing. Pairing those two advancements will enable faster printing and enhanced piezoelectric properties.

Publication in scientific journals is required for academic promotion at universities. It is also the method by which most family medicine faculty members disseminate their scholarly work, establish a reputation in their field, and develop a clinical, teaching, or scholarly expertise. Publications are able to reach a broader audience than are presentations, which makes them the epitome of academic scholarship. Most academic family physicians give presentations to students, residents, or colleagues as part of their regular job duties and at regional and national meetings, but few write articles based on those presentations.

1997-01-01

Regarding to PSA CIGB- IAEA project the center will be generating a panel of monoclonal antibodies against prostatic specific antigen (PSA) free and complexed to α1 antichymotrysin, and tissue polypeptide specific (TPS) antigen as potentially useful markers for the diagnosis of prostate and breast cancer using IRMA or RIA. The panel of monoclonal antibodies would be distributed in Cuba and another countries for the development of diagnostic Kits. The detailed objectives of the contract are: 1. To obtain a panel of monoclonal antibodies against prostatic specific antigen (PSA) complexed antichymotrysin. 2. To obtain a panel of monoclonal antibodies against free PSA. 3. To study the potential use for detect free or complexed PSA in the serum of patients with benign prostatic hypertrophy or prostatic neoplasia. 4. To obtain a panel of monoclonal antibodies against TPS. 5. To develop and validate IRMA or RIA assays using the panel of monoclonal antibodies. The objectives are designed according to the present knowledge on the field of monoclonal antibodies and diagnostic kits. Basic techniques for developing monoclonal antibodies (Mabs) have been used in our division for more than 10 years. The possibility to acquire commercial PSA antigen could reduced the overall time to obtain the Mabs, according with our experience. All these aspects support the idea that the proposing Cuban institutes are able to develop this research project and that its benefits will be applicable in the country and in the region

The latter modern means of learning, the study adds live on the Internet using search engines and not least e-learning method, which allows the study of bibliographic related materials in PDF or PPT, stacked and grouped on the basis of a curriculum imposed which can be accessed on a website via a user name and password. Innovative methods come to successfully use other file types than those mentioned above. The graphics in teaching technical subjects such as descriptive geometry can be achieved using animated PowerPoint files, allowing for visualization of steps to be taken, in the case of solving by drawing a descriptive geometry. Another innovative method relies on the use of HTML files, inspired by related sites help design software packages that can be used when teaching descriptive geometry that the technical design. Through this work, the author has proposed to present a new innovative method, which is inspired by the methods listed above, but involves using AVI files to teaching of computer-assisted type graphics or info graphics.

This paper summarizes developmental activities aiming at improving, the status of the Japan's System of safeguards. The integral tests are described which are now being implemented by the Japanese Government to check the effectiveness of the State's System, which must be maintained by the Government under the Safeguards Agreement between Japan and the IAEA under the Treaty on Non-Proliferation of Nuclear Weapons, ratified by Japan in June 1976. A joint experiment has been now implemented by the Nuclear Safety Bureau and the NMCC for knowing and improving the precision and accuracy of analytical measurements used at the bulk-facilities. JAERI, is conducting various R and D work on its own, and through cooperation with NMCC, NSB etc. The authors describe the results of non-destructive γ-spectrometry for the development of isotopic correlation techniques, as well as for the identification, and also refer briefly to measurement methods using the Fast Critical Assembly in JAERI. Measurement methods used in the Pu-fabrication facility of the PNC, and the problem of spent fuels application of safeguards for the reprocessing plant are discussed. The accounting reports coming from Japanese facilities are processed by the computer at the NMCC, and converted into (a) the State's material balance, and (b) the formats to be sent to IAEA. The authors discuss the experience of such data-processing as well as the developmental works for analysing MUF. As a part of the integral test, the experiences concerning planning and performance of inspection are discussed. The present status and future plans of the system of national analytical laboratories are described

Immunomodulators are agents, which can modulate the immune response to specific antigens, while causing least toxicity to the host system. Being part of the modern vaccine formulations, these compounds have contributed remarkably to the field of therapeutics. Despite the successful record maintained by these agents, the requirement of novel immunomodulators keeps increasing due to the increasing severity of diseases. Hence, research regarding the same holds great importance. In this review, we discuss the role of immunomodulators in improving performance of various vaccines used for counteracting most threatening infectious diseases, mechanisms behind their action and criteria for development of novel immunomodulators. Understanding the molecular mechanisms underlying immune response is a prerequisite for development of effective therapeutics as these are often exploited by pathogens for their own propagation. Keeping this in mind, the present research in the field of immunotherapy focuses on developing immunomodulators that would not only enhance the protection against pathogen, but also generate a long-term memory response. With the introduction of advanced formulations including combination of different kinds of immunomodulators, one can expect tremendous success in near future.

Voice and gesture-based 3D multimedia presentation tool

Science.gov (United States)

Fukutake, Hiromichi; Akazawa, Yoshiaki; Okada, Yoshihiro

2007-09-01

This paper proposes a 3D multimedia presentation tool that allows the user to manipulate intuitively only through the voice input and the gesture input without using a standard keyboard or a mouse device. The authors developed this system as a presentation tool to be used in a presentation room equipped a large screen like an exhibition room in a museum because, in such a presentation environment, it is better to use voice commands and the gesture pointing input rather than using a keyboard or a mouse device. This system was developed using IntelligentBox, which is a component-based 3D graphics software development system. IntelligentBox has already provided various types of 3D visible, reactive functional components called boxes, e.g., a voice input component and various multimedia handling components. IntelligentBox also provides a dynamic data linkage mechanism called slot-connection that allows the user to develop 3D graphics applications by combining already existing boxes through direct manipulations on a computer screen. Using IntelligentBox, the 3D multimedia presentation tool proposed in this paper was also developed as combined components only through direct manipulations on a computer screen. The authors have already proposed a 3D multimedia presentation tool using a stage metaphor and its voice input interface. This time, we extended the system to make it accept the user gesture input besides voice commands. This paper explains details of the proposed 3D multimedia presentation tool and especially describes its component-based voice and gesture input interfaces.

2014-12-01

Full Text Available This study deals with the thorny issue of the history of our country – the Gypsy slave trade, as it was presented in the press (1837-1844. We have identified a number of advertisements that reflect the type of trade, its form, prices for slaves, and institutions involved in such transactions. All this information is presented in a variety of contexts: the writings of foreign travelers, responses of public authorities, official documents. Studied documents leave no doubt as to the intention of the authorities to assimilate the Gypsies. There is also highlighted the role of the press as an intermediary in the Gypsy slave trade. Since we are talking about semi-official publications (Cantor de Avis şi Comerţ, Vestitorul Românesc, Albina Românească, it should be understood that these transactions were carried out with the consent of the heads of the relevant state entities. The study also highlights the stages of freeing the slaves.

Present status of design, research and development of nuclear fusion reactors and problems

International Nuclear Information System (INIS)

1983-04-01

Seven years have elapsed since the publication of ''Progress of nuclear fusion research and perspective toward the development of power reactors'' by the Atomic Energy Society of Japan in August, 1976. During this period, the research and development of nuclear fusion have changed from plasma physics to reactor technology, being conscious of the realization of fusion reactors. There are the R project in the Institute of Plasma Physics, Nagoya University, and the design and construction of JT-60 in Japan Atomic Energy Research Institute, to put it concretely. Now the research and development taking the economical efficiency into account are adopted. However, the type of fusion reactors is not reduced to tokamak type, accordingly the research and development to meet the diverse possibilities are forwarded. The progress of tokamak reactor research, core plasma design, nuclear design and shielding design, thermal structure design, the design of superconducting magnets, disassembling and repair, safety, economical efficiency, the conceptual design of other types than tokamak and others are reported.

Present status on world alternative energy developments to oil

International Nuclear Information System (INIS)

Reddington, J.

1980-01-01

The IEA was established about five years ago in the OECD immediately after the oil crisis, and 20 countries have participated in it. Progress was observed in the control of the expansion of energy demand. The energy utilization in IEA member countries became efficient due to the contribution of new technologies, and owing to the improvement of productivity, the growth of energy consumption was less than 1% despite the GDP grew at the yearly rate of 2.5%. The expansion of the utilization of natural gas and coal is promising, but the projects of nuclear power generation are behind schedule. The short term prospect in petroleum market is discussed, and the price of crude oil tends to be stabilized. ''The prospect of energy in the world by 2000'' will be published by the IEA in the latter half of 1980. The scale of the development of nuclear power generation was reduced because the prediction of the rate of power generation growth was changed from 5.2% to 3.1%. The effect of new energy technologies on future energy market has been studied by the support of 15 countries, and it was recommended to give financial aid to heat pumps, coal liquefaction and the efficient recovery of oil and natural gas. Also the techniques for operating existing facilities under strict environment and safety regulations have been studied. (Kako, I.)

Since the development of quantum physics in the early part of the 1900s, this field of study has made remarkable contributions to our civilization. Some of these advances include lasers, light-emitting diodes (LED), sensors, spectroscopy, quantum dots, quantum gravity and quantum entanglements. In 1998, the NASA Langley Research Center established a quantum technology committee to monitor the progress in this area and initiated research to determine the potential of quantum technology for future NASA missions. The areas of interest in quantum technology at NASA included fundamental quantum-optics materials associated with quantum dots and quantum wells, device-oriented photonic crystals, smart optics, quantum conductors, quantum information and computing, teleportation theorem, and quantum energetics. A brief review of the work performed, the progress made in advancing these technologies, and the potential NASA applications of quantum technology will be presented.

The MQC experiment on Rome: Present status and future developments

International Nuclear Information System (INIS)

Cosmelli, C.

1998-01-01

The study of phenomena related to the quantum behavior of macroscopic systems is subjected to new efforts both from theoretical and experimental point of view. The validity in fact of the description of macroscopic systems given by Quantum Mechanics is still under test, especially for what concerns the macrorealistic interpretation of the real world and the influence of dissipation on quantum systems. Many groups tried in the last few years to realize an experimental set-up to perform an MQC experiment; the intrinsic dissipation however limited the possibility to fulfill the experimental requirements. The technology for realizing high quality Josephson Junctions is now so advanced that in principle the tests proposed in the last ten years can hopefully performed with success. In the following we will present a short description of the basic principles for an MQC experiment, with special emphasis on the experiment planned by the Rome group. (author)

Markets, Availability, Notice, and Technical Performance of Terahertz Systems: Historic Development, Present, and Trends

Science.gov (United States)

Hochrein, Thomas

2015-03-01

Although a lot of work has already been done under the older terms "far infrared" or "sub-millimeter waves", the term "terahertz" stands for a novel technique offering many potential applications. The latter term also represents a new generation of systems with the opportunity for coherent, time-resolved detection. In addition to the well-known technical opportunities, an historical examination of Internet usage, as well as the number of publications and patent applications, confirms ongoing interest in this technique. These activities' annual growth rate is between 9 % and 21 %. The geographical distribution shows the center of terahertz activities. A shift from the scientific to more application-oriented research can be observed. We present a survey among worldwide terahertz suppliers with special focus on the European region and the use of terahertz systems in the field of measurement and analytical applications. This reveals the current state of terahertz systems' commercial and geographical availability as well as their costs, target markets, and technical performance. Component cost distribution using the example of an optical pulsed time-domain terahertz system gives an impression of the prevailing cost structure. The predication regarding prospective market development, decreasing system costs and higher availability shows a convenient situation for potential users and interested customers. The causes are primarily increased competition and larger quantities in the future.

The IAEA Standards for the Radioactive Discharge Control: Present Status and Future Development

International Nuclear Information System (INIS)

Balonov, M.; Linsley, G.; Robinson, C.; Cabianca, T.

2004-01-01

The International Atomic Energy Agency (IAEA) is the organization within the UN family with a statutory mandate to establish standards for the protection of health and environment against ionizing radiation, and to provide for the application of those standards. As part of these functions, the IAEA periodically reviews the status and continued relevance of the standards to the needs of its Member States. Recent work on the development of standards for the radioactive discharge control includes development of practical guidance for setting discharge limits, elaboration on methodology for the radiation protection of non-human species, and preparation of guidance on environmental monitoring for radiation protection purposes. Development of these safety documents is influenced by recent international and regional tendencies, based on social initiatives, to reduce radioactive discharges substantially below levels justified by radiological criteria. The IAEA has developed preliminary guidance on practical aspects of setting discharge limits, which included a review of national regulatory experience in this regard. This review suggested that societal pressures and regulatory practicalities results in discharge controls that were likely to be more restrictive that those that would be implied by formal optimization techniques. Regulatory review of authorizations includes a number of considerations, including predicted doses to members of the critical group, but the suitability of abatement forms a greater part in the decision-making process than allowed for in previous safety guidance. The IAEA has, in recent years, established a programme of work specifically addressing the development of safety standards on assessing the impact of ionizing radiation on non-human species, in co-operation with other relevant international organizations. The main issues arising will be summarised in the paper with the main focus on an exploration of the possible form of future regulatory

Report to the Congress: liquid metal fast breeder reactor program--past, present, and future, Energy Research and Development Administration

International Nuclear Information System (INIS)

1975-01-01

The past, present, and future of the liquid metal fast breeder reactor (LMFBR) program, the Nation's highest priority energy program, are studied. ERDA anticipates that the operation of the first large commercial breeder will start in 1987, and that 186 commercial-size breeders will be in operation by the year 2000. The breeder program is made up of six major areas, each dealing with an important element of technology: reactor physics; fuels and materials; fuel recycle; safety; component development; plant experience; and facilities used in the LMFBR program. ERDA is implementing a new system for administering, managing, and controlling the breeder program that will provide increased program visibility and control. Federal funding for breeder development was $168 million in FY 1971, accounting for 40% of the total Federal R and D energy budget; in FY 1976 Federal funding for this program will be $474 million, only 26% of total Federal funding for energy research. Besides Federal funds, over half a billion dollars have been or will be invested by industry over the next 5 to 10 years to develop the breeder and to build a demonstration plant. Five other nations--the United Kingdom, France, Japan, West Germany, and the Soviet Union--have a high priority national energy program for developing the LMFBR. These foreign breeder programs could contribute important data and information to the U.S. program

X-ray beam micro-analysis has advanced rapidly in these years in conjunction with the development of powerful X-ray sources. Among a variety of methods being attempted, the method using a collimated narrow beam has been important because of high brightness, and of usability in both regions of soft and hard X-rays. In the soft X-ray region, the focused beam is formed by a fresnel zone plate or a Schwaltzschild mirror assembly, and can be used for scanning transmission microscope or scanning photoelectron microscope. In the hard X-ray region, the beam is formed by grazing incidence mirrors, and can be used for X-ray fluorescence micro-analysis for obtaining elemental mapping. In this report, the recent progress on the soft X-ray scanning microscopy and the X-ray microprobe has been surveyed, together with the improvement on the related optical elements. (author) 84 refs

Making your presentation fun: creative presentation techniques

What possesses someone to volunteer and go through hoops and red tape to make a presentation at a conference? For that matter, why does anyone ever present anything to anyone? Actually, presentations are a fact of life and there are many reasons for doing a presentation and doing it well. New and existing staff need training and orientation to the way things are done here. Handing all of them a manual and hoping they read it is pretty much a waste of paper. On the other hand, an effective, entertaining and upbeat presentation on the relevant topics is more likely to stick with those people. They will even have a name and face to remember and seek out when they have an issue on or with that topic. This can be a very effective beginning for networking with new peers. The presenter is seen as knowledgeable, as a source of information on company topics and possibly evaluated as a potential mentor or future manager. Project staff and/or peers benefit from clear, concise, presentations of topical knowledge. This is one way that a group working on various aspects of the same project or program can stay in touch and in step with each other. Most importantly, presentations may be the best or only door into the minds (and budgets) of management and customers. These presentations are a wonderful opportunity to address legal and compliance issues, budget, staffing, and services. Here is a chance, maybe the only one, to demonstrate and explain the wonderfulness of a program and the benefit they get by using the services offered most effectively. An interactive presentation on legal and compliance issues can be an effective tool in helping customers and/or management make good risk management decisions.

The introduction of future emission limits for marine diesel engines requires an improved understanding of the fuel injection process and mixture formation as well as the development of robust and powerful tools to calculate the emission generation. This publication presents research results of the project partners AVI Deutschland GmbH and Rostock University obtained in the associated project EMI-MINI II. Objective of the experimental part of the work is the fundamental investigation of the mixture formation at cold and evaporative conditions in a high-pressure and high-temperature chamber by means of optical methods. For the measurements, a modem, heavy fuel capable single circuit common-rail injector of a medium speed diesel engine is applied. Based on the experimental results a calibration and validation of spray break-up and evaporation models is done. The models are applied in a specific simulation approach in order to predict engine emissions. Characteristic feature of the chosen approach is the consideration of specific nozzle internal flow conditions as boundary conditions for the spray break-up models and thus for the ignition, combustion and emission generation. The presented results demonstrate that the applied models are very sufficient to calculate injection and mixture formation processes. By comparing calculated engine emissions to experimental results obtained by WTZ Rosslau gGmbH it is shown that the presented simulation approach is capable to predict the impact of varying engine parameters on NO{sub x}- and soot emissions effectively.

Mycoplasma pneumoniae is a major cause of community-acquired pneumonia. Because most children are not imaged prior to onset of clinical symptoms, the appearance of early Mycoplasma infection has not been extensively studied. We present the case of an 11-year-old boy with large pulmonary masses incidentally detected during spine MRI evaluation for scoliosis. Eight days later, the patient developed acute respiratory symptoms, and the masses seen previously had evolved into a diffuse bronchiolitis. Diagnostic testing identified Mycoplasma pneumoniae as the likely etiology. We briefly review chest CT findings of infection by Mycoplasma and compare them to this unusual presentation of Mycoplasma pneumonia with subclinical imaging findings. (orig.)

We have redesigned a tried-and-true laboratory exercise into an inquiry-based team activity exploring microbial growth control, and implemented this activity as the basis for preparing a scientific poster in a large, multi-section laboratory course. Spanning most of the semester, this project culminates in a poster presentation of data generated from a student-designed experiment. Students use and apply the scientific method and improve written and verbal communication skills. The guided inquiry format of this exercise provides the opportunity for student collaboration through cooperative learning. For each learning objective, a percentage score was tabulated (learning objective score = points awarded/total possible points). A score of 80% was our benchmark for achieving each objective. At least 76% of the student groups participating in this project over two semesters achieved each learning goal. Student perceptions of the project were evaluated using a survey. Nearly 90% of participating students felt they had learned a great deal in the areas of formulating a hypothesis, experimental design, and collecting and analyzing data; 72% of students felt this project had improved their scientific writing skills. In a separate survey, 84% of students who responded felt that peer review was valuable in improving their final poster submission. We designed this inquiry-based poster project to improve student scientific communication skills. This exercise is appropriate for any microbiology laboratory course whose learning outcomes include the development of scientific inquiry and literacy.

Theory of defects in Si and Ge: Past, present and recent developments

Estreicher, S.K.; Backlund, D.; Gibbons, T.M.

2010-01-01

Over the past few decades, considerable progress has been achieved in the theoretical predictions of a wide range of properties of defects in semiconductors. In addition to structures, energetics, spin and charge densities, theory now routinely predicts accurate vibrational properties of defects, and thus connects to the optical characterization of light impurities. However, the positions of gap levels have yet to be predicted with systemically reliable accuracy. Today, supercells much larger than in the past are being used to describe defect centers from first principles. Systems large enough to study the dynamics of extended defects can be handled near the first-principles level. This paper contains a brief review of the key developments that have rendered theory quantitatively useful to experimentalists and an overview of the current 'state-of-the-art' and ongoing developments. Some of the remaining challenges are discussed, with examples in Si and Ge.

Teratology – past, present and future

2012-01-01

Teratology is the science that studies the causes, mechanisms, and patterns of abnormal development. The authors present an updated overview of the most important milestones and stages of the development of modern teratology. Development of knowledge and society led to the recognition that causes of congenital developmental disorders (CDDs) might be caused by various mechanical effects, foetal diseases, and retarded or arrested development of the embryo and foetus. Based on the analysis of the historical development of hypotheses and theories representing a decisive contribution to this field, we present a survey of the six Wilson′s fundamental principles of teratology. The aim of observing these principles is to get insight into developmental relations and to understand mechanisms of action on the level of cell populations (elementary morphogenetic processes), tissues and organs. It is important to realise that any negative intervention into the normal course of these processes, either on genetic or non-genetic basis, inevitably leads to a sequence of subsequent changes resulting in CDDs. Moreover, the classical toxicologic monotonic dose-response paradigm recently has been challenged by the so-called “low dose-hypothesis”, particularly in the case of endocrine active substances. These include some pesticides, dioxins, polychlorobiphenyls (PCBs), and bisphenol A. Despite modern approaches of molecular biology and genetics, along with top diagnostic techniques, we are still not able to identify the actual cause in more than 65 to 70% of all congenital defects classified as having an unknown etiology. Today CDDs include any birth defect, either morphological, biochemical, or behavioural. PMID:23554558

Atypical presentations of Wolframs syndrome

Full Text Available Background: Wolfram syndrome is a rare hereditary or sporadic neurodegenerative disorder also known as DIDMOAD. The classically described presentation is of insulin-dependent diabetes, followed by optic atrophy, central diabetes insipidus, and sensory neural deafness. Also included are less well-described presentations of Wolframs syndrome. We here present three cases of atypical presentation of this syndrome. Case 1: A 15-year-old boy with insulin-dependent diabetes was presented for evaluation of depressive symptoms associated with suicidal tendency. Neuropsychiatric manifestations are described with Wolframs syndrome, and wolframin gene, in recessive inheritance, is associated with psychiatric illnesses without other manifestations of Wolframs syndrome. Case 2: A 17-year-old diabetic boy on insulin with good control of blood sugar presented for evaluation of delayed puberty. Central hypogonadism and other anterior pituitary hormone dysfunctions are the less publicized hormone dysfunctions in Wolframs syndrome. Case 3: A 23-year-old female who was on insulin for diabetes for the past 14 years, got admitted for evaluation of sudden loss of vision. This patient had developed a vitreous hemorrhage and, on evaluation, was found to have optic atrophy, sensory neural hearing loss, and diabetes insipidus, and presented differently from the gradual loss of vision described in Wolframs syndrome. Conclusion: Wolframs syndrome being a multisystem degenerative disorder can have myriad other manifestations than the classically described features. Neuropsychiatric manifestations, depression with suicidal risk, central hypogonadism, and secondary adrenal insufficiency are among the less well-described manifestations of this syndrome.

Ebola is a highly virulent pathogen causing severe hemorrhagic fever with a high case fatality rate in humans and non-human primates (NHPs). Although safe and effective vaccines or other medicinal agents to block Ebola infection are currently unavailable, a significant effort has been put forth to identify several promising candidates for the treatment and prevention of Ebola hemorrhagic fever. Among these, recombinant-virus based vectors have been identified as potent vaccine candidates with some affording both pre- and post-exposure protection from the virus. Recently, Investigational New Drug (IND) applications have been approved by the United States (U.S.) Food and Drug Administration (FDA) and Phase I clinical trials initiated for two small molecule therapeutics, 1) anti-sense phosphorodiamidate morphino oligomers (PMOs: AVI-6002, AVI-6003), and 2) lipid-nanoparticle/small interfering RNA (LNP/siRNA: TKM-Ebola). These potential alternatives to vector-based vaccines require multiple doses to achieve therapeutic efficacy which is not ideal with regard to patient compliance and outbreak scenarios. These concerns have fueled a quest for even better vaccination and treatment strategies. Here, we summarize recent advances in vaccines or post-exposure therapeutics for prevention of Ebola hemorrhagic fever. The utility of novel pharmaceutical approaches to refine and overcome barriers associated with the most promising therapeutic platforms will also be discussed. PMID:23813435

Objective The Nagasaki Kunchi Festival is one of the most famous festivals in Nagasaki. The bearers the floats that are used in this festival undergo long-term training for the performance. However, there have not been any studies on the effects of this training on the health of the float bearers. Methods Thirty-four men ranging in age from 20 to 49 years (mean age: 35.77.6 years) were included in the study. We examined the following parameters before and after the training: body weight (BW), body mass index (BMI), body fat percentage, muscle volume, systolic blood pressure (SBP), diastolic blood pressure (DBP), pulse rate (PR), pulse pressure (PP), bearing power, arterial pressure volume index (API), and arterial velocity pulse index (AVI). Results For all participants, the BW, BMI, body fat percentage, and PR were significantly decreased, and the muscle volume and bearing power were significantly increased after the training; however, there were no significant changes in the SBP, DBP, PP, API, or AVI. In the participants with hypertension, in addition to decreases in BW, BMI, body fat percentage, PR, and PP, the SBP, DBP, and API were significantly decreased after the training. Conclusion Training for bearing a float during Nagasaki Kunchi effectively improved the body structure of all participants and reduced the BP and API in participants with hypertension.

Lopez, C

1994-01-01

This address by the Peruvian delegation to the Third Preparatory Committee Meeting for the International Conference on Population and Development focuses on four points in the proposed Plan of Action that might require further development. First, the link between drug trafficking and environmental degradation should be recognized. Cultivation of narcotic plants contributes to deforestation of the tropical forest and contamination of rivers, and along with terrorism has caused considerable population movement in Peru. The second point is that widespread poverty, limited investment in human capital, insufficient institutional capacity, and the external debt burden of the developing countries are clearly interrelated with sociodemographic processes and decisively affect the capacity of the nation to implement population policies and programs as a function of current and future international commitments. The third point is that, in the area of information, education, and communication, attention should be given to the entire life cycle and the entirety of themes related to population. Finally, coordinated programs between public and private institutions and nongovernmental organizations at the national level, and between the U.N. Population Fund, the Population Commission, and the Commission on Sustainable Development at the international level, should be organized to assure effective follow-up on Plan of Action proposals and agreements. Peru has participated in a wide variety of international conferences and activities related to population, and was a major participant in the subregional preparatory conference of the Andean nations.

The present state and future of the development of dimension stone mining in Slovak conditions

2005-03-01

Full Text Available In comparing to both ores and energetical minerals there are occurences of extremly rich non-methallics minerals on the Slovak territory. These minerals represent very large-scale sortiment with a considerable amount of verified reserves. Reserves of magnesite, salt rock, dolomite, limestone, talc, bentonite, clays and another construction minerals present many possibilities of their industrial utilization. A specific case is the mining of dimension stones such as stable ingeneous,sedimentary and metamorphic rocks that are mined in the open-pit blocks. Applicable to the production of both ingeneous stone and gross stone [3].The open-pit mining and dimension stone processing by the both above mentioned stone productions forms are focused mainly to the external and internal building industry. Despite of the fact that the natural reserves of dimension stone are limited at the Slovak territory, being distributed at large numbers of open-pits mines, from the point of view of the next development of the dimension stone industry its technical and economic vitalitycan be expected. The paper deals with both the technological and ecological mining problems of dimension stone and shows the possibilities how to improve both the works productivity and quality of products including the ecological impacts by the dimension stone mining.

1997-10-20

The present situation was introduced of the geothermal power generation in Kyushu. In Kyushu, where there are lots of volcanos and abundant geothermal resources, the geothermal exploration has been made since long ago. Three non-utility use units at three geothermal power generation points and six commercial use units at five points are now in operation in Kyushu. The total output is approximately 210 MW, about 40% of the domestic geothermal power generation. At Otake and Hacchobaru geothermal power plants, the Kyushu Electric Power Company made the geothermal resource exploration through the installation/operation of power generation facilities. At the Otake power plant, a geothermal water type single flashing system was adopted first in the country because of its steam mixed with geothermal water. At the Hacchobaru power plant, adopted were a two-phase flow transportation system and a double flashing system in which the geothermal water separated from primary steam by separator is more reduced in pressure to take out secondary steam. Yamakawa, Ogiri and Takigami power plants are all for the joint exploration. Geothermal developers drill steam wells and generate steam, and the Kyushu Electric Power Company buys the steam and uses it for power generation. 5 figs., 1 tab.
