Full Text Available The article considers methodological and empirical aspects of cross-cultural communica-tions under the economic and cultural globalization that determined the free movement of labor migrants around the world though this process is accompanied by certain difficulties. The authors believe that even a theoretically prepared person that knows about the influence of cultural differences on the organizational management in different countries will experience a cultural shock when working abroad. The cultural shock is a discomfort, frustration and even depression caused by getting into an unfamiliar environment. At the applied level, the authors analyze the so-called ‘cross-cultural experiments’ - attempts of an individual (a working specialist of a certain nation to test one’s strength, skills, and professional competencies in a foreign company. The authors’ sociological study of a cultural benchmarking type consisted of two stages. At the first stage, foreigners working in the capital of the Republic of Sakha (Yakutia were inter-viewed; at the second stage, the Russians working abroad, mainly in the USA, were interviewed. The migra-tion flows from China have recently intensified in Yakutia, but the overwhelming majority of labor migrants are still from West and Central Asia, mainly from Tajikistan, Kyrgyzstan, and Armenia. The foreigners working in Yakutia and Russians working abroad experience same difficulties of adaptation in a new col-lective. Friends, relatives, members of the ethnic community, but not specially trained cross-cultural coaches and mentors, help them with adaptation. Such a personnel technology as selection, recruitment and headhunt-ing works reasonably well, while other HR technologies of cross-cultural management (motivation, feedback, etc. are still lagging behind. The authors insist on introducing courses on cross-cultural adaptation in interna-tional groups both in Russia and abroad together with a system of the so

Cultural based preconceptions in aesthetic experience of architecture

Full Text Available On a broader scale, the aim of this paper is to examine theoretically the effects a cultural context has on the aesthetic experience of images existing in perceived reality. Minimalism in architecture, as direct subject of research, is a field of particularities in which we observe functioning of this correlation. Through the experiment with the similarity phenomenon, the paper follows specific manifestations of general formal principles and variability of meaning of minimalism in architecture in limited areas of cultural backgrounds of Serbia and Japan. The goal of the comparative analysis of the examples presented is to indicate the conditions that may lead to a possibly different aesthetic experience in two different cultural contexts. Attribution of different meanings to similar formal visual language of architecture raises questions concerning the system of values, which produces these meanings in their cultural and historical perspectives. The establishment of values can also be affected by preconceptions resulting from association of perceived similarities. Are the preconceptions in aesthetic reception of architecture conditionally affected by pragmatic needs, symbolic archetypes, cultural metaphors based on tradition or ideologically constructed dogmas? Confronting philosophical postulates of the Western and Eastern traditions with the transculturality theory of Wolfgang Welsch, the answers may become more available.

2018-05-01

Women remain severely under-represented in engineering in Australia as in all Western countries. This limits the pool of talent, standpoints and approaches within the profession. Furthermore, this under-representation equates to restriction of the benefits of being an engineer mainly to men. Gendered workplace experiences have been found to contribute to women leaving the profession. In this study we explore students' experiences of gendered cultures in engineering workplaces, using interviews with a purposive sample of 13 students (4 male) recruited following a previous survey. Although the overall experience of workplace learning is positive for many students, male and female engineering students reported experiences consistent with masculine cultures. Educators and employers must proactively lead improvements to the culture in engineering workplaces, prepare students for gendered workplaces and support students to reflect during and after workplace experiences. The experiences presented here could be adapted to enhance inclusivity training.

Arundell, Fiona; Mannix, Judy; Sheehan, Athena; Peters, Kath

2018-04-01

To describe midwifery students' practice experience and to explore facilitators and barriers to positive clinical learning experiences. Practice experience is a vital component of every midwifery course. Course dissatisfaction and attrition of midwifery students has been attributed to sub-optimal practice experiences. Events or actions experienced by midwifery students that trigger dissatisfaction and attrition need to be identified. A meta-synthesis was based on that developed by Noblit and Hare. Students perceive workplaces as poorly prepared for their arrival and subsequent support. Students' experience in the practice setting is influenced by the existing workplace culture. Workplace culture influences institutional functioning and individuals within the culture. Enculturation of students into the midwifery culture and subsequent learning is affected by the support received. The practice experience of midwifery students was profoundly influenced by workplace culture. Students tended to have polarized accounts of their experience that were predominantly negative. To provide an optimal environment for midwifery students; midwifery managers and individual midwives need to be aware of the facilitators and barriers to midwifery student development in the practice setting. © 2017 John Wiley & Sons Ltd.

Concerns around organisational learning culture limit nursing student placements in aged care settings to first year experiences. Determine the impact of an extended staff capacity building program on students' experiences of the organisational learning culture in the aged care setting. Pre and post-test design. A convenience sample of first, second and third year Bachelor of Nursing students attending placements at three residential aged care facilities completed the Clinical Learning Organisational Culture Survey. Responses between the group that attended placement before the program (n = 17/44; RR 38%) and the group that attended following the program (n = 33/72; RR 45%) were compared. Improvements were noted in the areas of recognition, accomplishment, and influence, with decreases in dissatisfaction. Organisational investment in building staff capacity can produce a positive learning culture. The aged care sector offers a rich learning experience for students when staff capacity to support learning is developed.

The increase in the incidence of HIV/AIDS among minorities in the United States and in certain developing nations has prompted new intervention priorities, stressing the adaptation of efficacious interventions for diverse and marginalized groups. The experiences of Florida International University's AIDS Prevention Program in translating HIV primary and secondary prevention interventions among these multicultural populations provide insight into the process of cultural adaptations and address the new scientific emphasis on ecological validity. An iterative process involving forward and backward translation, a cultural linguistic committee, focus group discussions, documentation of project procedures, and consultations with other researchers in the field was used to modify interventions. This article presents strategies used to ensure fidelity in implementing the efficacious core components of evidence-based interventions for reducing HIV transmission and drug use behaviors and the challenges posed by making cultural adaptation for participants with low literacy. This experience demonstrates the importance of integrating culturally relevant material in the translation process with intense focus on language and nuance. The process must ensure that the level of intervention is appropriate for the educational level of participants. Furthermore, the rights of participants must be protected during consenting procedures by instituting policies that recognize the socioeconomic, educational, and systemic pressures to participate in research.

Critical experiments for large scale enriched uranium solution handling

Tanner, J.E.; Forehand, H.M.

1985-01-01

The authors have performed 17 critical experiments with a concentrated aqueous uranyl nitrate solution contained in an annular cylindrical tank, with annular cylindrical absorbers of stainless steel and/or polyethylene inside. k/sub eff/ calculated by KENO IV, employing 16-group Hansen-Roach cross sections, average 0.977. There is a variation of the calculational bias among the separate experiments, but it is too small to allow assigning it to specific components of the equipment. They are now performing critical experiments with a more concentrated uranyl nitrate solution in pairs of very squat cylindrical tanks with disc shaped absorbers and reflectors of carbon steel, stainless steel, nitronic-50, plain and borated polyethylene. These experiments are in support of upgrading fuel reprocessing at the Idaho Chemical Processing Plant

Particle Trajectories in Rotating Wall Cell Culture Devices

Ramachandran N.; Downey, J. P.

Cell cultures are extremely important to the medical community since such cultures provide an opportunity to perform research on human tissue without the concerns inherent in experiments on individual humans. Development of cells in cultures has been found to be greatly influenced by the conditions of the culture. Much work has focused on the effect of the motions of cells in the culture relative to the solution. Recently rotating wall vessels have been used with success in achieving improved cellular cultures. Speculation and limited research have focused on the low shear environment and the ability of rotating vessels to keep cells suspended in solution rather than floating or sedimenting as the primary reasons for the improved cellular cultures using these devices. It is widely believed that the cultures obtained using a rotating wall vessel simulates to some degree the effect of microgravity on cultures. It has also been speculated that the microgravity environment may provide the ideal acceleration environment for culturing of cellular tissues due to the nearly negligible levels of sedimentation and shear possible. This work predicts particle trajectories of cells in rotating wall vessels of cylindrical and annular design consistent with the estimated properties of typical cellular cultures. Estimates of the shear encountered by cells in solution and the interactions with walls are studied. Comparisons of potential experiments in ground and microgravity environments are performed.

Heavy metal incorporation in foraminiferal calcite: results from multi-element enrichment culture experiments with Ammonia tepida

Directory of Open Access Journals (Sweden)

G.-J. Reichart

2010-08-01

Full Text Available The incorporation of heavy metals into carbonate tests of the shallow water benthic foraminifer Ammonia tepida was investigated under controlled laboratory conditions. Temperature, salinity, and pH of the culture solutions were kept constant throughout the duration of this experiment, while trace metal concentrations were varied. Concentrations of Ni, Cu, and Mn were set 5-, 10-, and 20 times higher than levels found in natural North Sea water; for reference, a control experiment with pure filtered natural North Sea water was also analysed. The concentrations of Cu and Ni from newly grown chambers were determined by means of both μ-synchrotron XRF and Laser Ablation Inductively Coupled Plasma Mass Spectroscopy (LA-ICP-MS. The results of both independent analytical techniques agreed within the analytical uncertainty. In general, the concentration of the analysed elements in the tests increased in line with their concentration in the culture solutions. Potential toxic and/or chemical competition effects might have resulted in the decreased incorporation of Ni and Cu into the calcite of the specimens exposed to the highest elemental concentrations. Mn incorporation exhibited large variability in the experiment with the 20-fold increased element concentrations, potentially due to antagonistic effects with Cu. The partition coefficients of Cu and Ni were calculated to be 0.14 ± 0.02 and 1.0 ± 0.5, respectively, whereas the partition coefficient of Mn was estimated to be least 2.4. These partition coefficients now open the way for reconstructing past concentrations for these elements in sea water.

The previous experiments proved the volatility of polonium form culture medium in which microorganisms were propagated from seed of seawater, river water or pond water, therefore we did not know what kind of species are responsible to Po volatility. To search microorganisms, which concerned with Po emission we carried out culture experiments using known microorganisms. Three microorganisms were examined; Escherichia coli K-12, Bacillus subtilis and Chromobacterium violaceum. The microorganisms were pre-cultured in LB medium at 30 degree C and a small portion of the pre-cultured was transferred to a culture bottle in which LB medium and 208 Po tracer were contained. The culture was done at 30 degree C with shaking the culture bottle and air passed through a filter was introduced. The Po volatilized was transferred into the trap vials in which scintillator for liquid scintillation counting (LSC) was contained. The Po activity was measured by LSC. All of the microorganisms examined volatilized Po but their ability was quite different each other. Highest ability was observed on Chromobacterium violaceum and then Escherichia coli K-12 followed by Bacillus subtilis, the relative magnitude of the ability was 10 2 , 10, 1, respectively. Chromobacterium violaceum and Escherichia coli K-12 showed high volatility for the first 24 h but Escherichia coli K-12 showed a decrease thereafter. However high volatility was continued on Chromobacterium violaceum during the culture. The low culture temperature suppressed Po volatility, supporting biologically mediated Po emission from the culture.

[Mental health beliefs between culture and subjective illness experience].

Subjective health beliefs are representations about pathogenesis, course and treatment options of psychic as well as somatic illnesses. They are important for a psychotherapeutic interaction as well as for a stable drug adherence. However, it remains unclear whether these representations are primarily affected by the cultural background or by an individual's specific illness experiences, a question of increasing importance in our era of globalized migration. The study sample consisted of 203 Austrians (125 with schizophrenia, 78 with obsessivecompulsive disorder) and 190 Pakistanis (120 with schizophrenia, 70 with obsessive-compulsive disorder). All patients completed the "Causal Explanations of Mental Disorders" (CEMD), a 41-item self-rating questionnaire. Pakistani patients reported magic-religious oriented mental health beliefs more frequently. In contrast, Austrians' beliefs are more often in line with the bio-psychosocial explanations of Western medicine. Concerning mental health beliefs the cultural background seems to be more important than the subjective experience with a distinctive mental disorder. Although the subjective experience is of importance for the shape of illnessspecific cognitions, mental health beliefs are primarily caused by the patients' socio-cultural origin. It is a challenge for psychiatry to improve the co-operation with culture-anthropology and other social sciences.

Cultural experiences come in many different forms, such as immersion in a particular linguistic community, exposure to faces of people with different racial backgrounds, or repeated encounters with music of a particular tradition. In most circumstances, these cultural experiences are asymmetric, meaning one type of experience occurs more frequently than other types (e.g., a person raised in India will likely encounter the Indian todi scale more so than a Westerner). In this paper, we will discuss recent findings from our laboratories that reveal the impact of short- and long-term asymmetric musical experiences on how the nervous system responds to complex sounds. We will discuss experiments examining how musical experience may facilitate the learning of a tone language, how musicians develop neural circuitries that are sensitive to musical melodies played on their instrument of expertise, and how even everyday listeners who have little formal training are particularly sensitive to music of their own culture(s). An understanding of these cultural asymmetries is useful in formulating a more comprehensive model of auditory perceptual expertise that considers how experiences shape auditory skill levels. Such a model has the potential to aid in the development of rehabilitation programs for the efficacious treatment of neurologic impairments.

Regret is the prototypical decision-related emotion. Most theory and research on regret comes from the United States and Europe, but recent research has suggested potential cross-cultural differences in regret. We examined generality and cultural variation in the experience of regret. A cross-cultural study compared experiences of regret with those of disappointment and guilt as reported by participants from the United States (n = 143), the Netherlands (n = 147), Israel (n = 148), and Taiwan (n = 115). We found strong evidence for generality of the distinct emotion components of regret, compared with those of disappointment and guilt. We also found cultural variation in the frequency and intensity of regret in intrapersonal situations (regrets about outcomes affecting the self) and interpersonal regrets (regrets about outcomes affecting others). Whereas in the U.S. sample, regret was experienced more intensely in intrapersonal than interpersonal situations, both emotions were experienced more intensely in interpersonal situations in the Taiwanese sample.

Full Text Available The increasing mental demands of healthcare work call for developing complementary health promotion strategies. Cultural leisure activities have long been recognized as a source of wellbeing and coping for employees. Yet, little is known about implementation of employer-provided cultural activities—how they are encountered and experienced. In this study, a public sector hospital department offered monthly cultural events for personnel: Theater, concerts, musicals, dance-performances, museum visits and sight-seeing. A digital questionnaire was sent to hospital staff (N = 769 to ask about their participation in employer-provided cultural activities during the past 6 months. The motives and obstacles for participation, and the quality of experience of the cultural events, were explored quantitatively and qualitatively. The main motives for participation were related to well-being, content of cultural events and invitations from employer or colleagues. For some, the participation was hampered by work-shifts and missing information. The participants experienced recreation, relaxation and psychological detachment from strain, which is essential for recovery. Community participation was more common than individual participation. Shared cultural experiences among employees may increase the social capital at workplace, but equal access for all employees should be guaranteed.

Response of non-added solutes during nutrient addition experiments in streams

Rodriguez-Cardona, B.; Wymore, A.; Koenig, L.; Coble, A. A.; McDowell, W. H.

2015-12-01

Nutrient addition experiments, such as Tracer Additions for Spiraling Curve Characterization (TASCC), have become widely popular as a means to study nutrient uptake dynamics in stream ecosystems. However, the impact of these additions on ambient concentrations of non-added solutes is often overlooked. TASCC addition experiments are ideal for assessing interactions among solutes because it allows for the characterization of multiple solute concentrations across a broad range of added nutrient concentrations. TASCC additions also require the addition of a conservative tracer (NaCl) to track changes in conductivity during the experimental manipulation. Despite its use as a conservative tracer, chloride (Cl) and its associated sodium (Na) might change the concentrations of other ions and non-added nutrients through ion exchange or other processes. Similarly, additions of biologically active solutes might change the concentrations of other non-added solutes. These methodological issues in nutrient addition experiments have been poorly addressed in the literature. Here we examine the response of non-added solutes to pulse additions (i.e. TASCC) of NaCl plus nitrate (NO3-), ammonium, and phosphate across biomes including temperate and tropical forests, and arctic taiga. Preliminary results demonstrate that non-added solutes respond to changes in the concentration of these added nutrients. For example, concentrations of dissolved organic nitrogen (DON) in suburban headwater streams of New Hampshire both increase and decrease in response to NO3- additions, apparently due to biotic processes. Similarly, cations such as potassium, magnesium, and calcium also increase during TASCC experiments, likely due to cation exchange processes associated with Na addition. The response of non-added solutes to short-term pulses of added nutrients and tracers needs to be carefully assessed to ensure that nutrient uptake metrics are accurate, and to detect biotic interactions that may

Correlative light-electron microscopy of cells in a natural environment of aqueous liquid facilitates high-throughput observation of protein complex formation. ASEM allows the inverted SEM to observe the wet sample from below, while an optical microscope observes it from above quasi-simultaneously. The disposable ASEM dish with a silicon nitride (SiN) film window can be coated variously to realize the primary-culture of substrate-sensitive cells in a few milliliters of culture medium in a stable incubator environment. Neuron differentiation, neural networking, proplatelet-formation and phagocytosis were captured by optical or fluorescence microscopy, and imaged at high resolution by gold-labeled immuno-ASEM with/without metal staining.

Correlative light-electron microscopy of cells in a natural environment of aqueous liquid facilitates high-throughput observation of protein complex formation. ASEM allows the inverted SEM to observe the wet sample from below, while an optical microscope observes it from above quasi-simultaneously. The disposable ASEM dish with a silicon nitride (SiN) film window can be coated variously to realize the primary-culture of substrate-sensitive cells in a few milliliters of culture medium in a stable incubator environment. Neuron differentiation, neural networking, proplatelet-formation and phagocytosis were captured by optical or fluorescence microscopy, and imaged at high resolution by gold-labeled immuno-ASEM with/without metal staining. Fas expression on the cell surface was visualized, correlated to the spatial distribution of F-actin. Axonal partitioning was studied using primary-culture neurons, and presynaptic induction by GluRδ2-N-terminus-linked fluorescent magnetic beads was correlated to the presynaptic-marker Bassoon.

A cross-cultural experience at midnight.

Niimura, Junko

2013-04-01

This essay is a story about a cultural interaction between a Japanese mother and a Chinese young mother whose baby was premature. When I was staying in a hospital in Japan to deliver my second son, I shared a room with this mother. She delivered her baby very early-at 25 weeks of pregnancy. Her baby received extensive medical treatment in the neonatal intensive care unit. However, this Chinese young mother appeared bewildered about the communication from the Japanese hospital staff because Japanese hospital's communication about the medical care of premature infants was very different from China. One day at midnight, she spoke with me about having deep uneasiness about the situation and having many unanswered questions. After this cultural experience, I began to think more deeply about cultural differences in terms of health and illness and the influence of universal health insurance on the lives of the families of premature infants. I also recognized that the value of life is not calculated in the same fashion globally. © 2013 Wiley Publishing Asia Pty Ltd.

2007-01-01

The toxicity of two toxic elements, arsenic (As) and cadmium (Cd) (individually or in combination) on root elongation of wheat seedlings (Triticum aestivum, L.) were investigated both in hydroponics and in soils freshly spiked with the toxic elements. Median effective concentration (EC 50 ) and non-observed effect concentration (NOEC) were used to investigate the toxic thresholds and potencies of the two elements. The EC 50 for As was 0.97 μM in hydroponics and 196 mg kg -1 in soil, and 4.32 μM and 449 mg kg -1 for Cd, respectively. Toxic unit (TU) and additive index (AI) concepts were introduced to determine the combined outcomes, and different behaviors were obtained: synergism in solution culture (EC 50mix = 0.36TU mix and AI: 1.76) and antagonism in soil experiments (EC 50mix = 1.49TU mix and AI: -0.33). Furthermore, the data of soil bioavailable As and Cd cannot explain the discrepancy between the results derived from soil and hydroponics experiments

Stochastic analysis of transport of conservative solutes in caisson experiments

International Nuclear Information System (INIS)

Dagan, G.

1995-01-01

The Los Alamos National Laboratory has conducted in the past a series of experiments of transport of conservative and reactive solutes. The experimental setup and the experimental results are presented in a series of reports. The main aim of the experiments was to validate models of transport of solutes in unsaturated flow at the caisson intermediate scale, which is much larger than the one pertaining to laboratory columns. First attempts to analyze the experimental results were by one-dimensional convective-dispersion models. These models could not explain the observed solute breakthrough curves and particularly the large solute dispersion in the caisson effluent Since there were some question marks about the uniformity of water distribution at the caisson top, the transport experiments were repeated under conditions of saturated flow. In these experiments constant heads were applied at the top and the bottom of the caisson and the number of concentration monitoring stations was quadrupled. The analysis of the measurements by the same one-dimensional model indicated clearly that the fitted dispersivity is much larger than the pore-sole dispersivity and that it grows with the distance in an approximately linear fashion. This led to the conclusion, raised before, that transport in the caisson is dominated by heterogeneity effects, i.e. by spatial variability of the material Such effects cannot be captured by traditional one-dimensional models. In order to account for the effect of heterogeneity, the saturated flow experiments have been analyzed by using stochastic transport modeling. The apparent linear growth of dispersivity with distance suggested that the system behaves like a stratified one. Consequently, the model of Dagan and Bresier has been adopted in order to interpret concentration measurements. In this simple model the caisson is viewed as a bundle of columns of different permeabilities, which are characterized by a p.d.f. (probability denasity function)

Iodine uptake by spinach (Spinacia oleracea L.) plants grown in solution culture: effects of iodine species and solution concentrations.

Science.gov (United States)

Zhu, Y-G; Huang, Y-Z; Hu, Y; Liu, Y-X

2003-04-01

A hydroponic experiment was carried out to investigate the effects of iodine species and solution concentrations on iodine uptake by spinach (Spinacia oleracea L.). Five iodine concentrations (0, 1, 10, 50 and 100 microM) for iodate (IO(3)(-)) and iodide (I(-)) were used. Results show that higher concentrations of I(-) (> or =10 microM) had some detrimental effect on plant growth, while IO(3)(-) had little effect on the biomass production of spinach plants. Increases in iodine concentration in the growth solution significantly enhanced I concentrations in plant tissues. The detrimental effect of I(-) on plant growth was probably due to the excessively high accumulation of I in plant tissues. The solution-to-spinach leaf transfer factors (TF(leaf), fresh weight basis) for plants treated with iodide were between 14.2 and 20.7 at different solution concentrations of iodide; TF(leaf) for plants treated with iodate decreased gradually from 23.7 to 2.2 with increasing solution concentrations of iodate. The distribution coefficients (DCs) of I between leaves and roots were constantly higher for plants treated with iodate than those treated with iodide. DCs for plants treated with iodide increased with increasing solution concentrations of iodide, while DCs for plants treated with iodate (around 5.5) were similar across the range of solution concentrations of iodate used in this experiment. The implications of iodine accumulation in leafy vegetables in human iodine nutrition are also discussed. Copyright 2002 Elsevier Science Ltd.

The criticality station of Dijon involves three cells, shielded by concrete walls of 1.46 meter thickness. Those cells are designed to contain the criticality experiment apparatus. The engineering building is also involving: one chemical laboratory where plutonium solutions are prepared, one analysis laboratory, several activated solutions storages, several control rooms, One cell contains the B system, which is designed to study: annular cylindrical geometries, slab of 10 cm thickness, interaction between annular cylinders. This report includes the first results given by experiments on annular cylinders defined by their own geometry (outer and inner diameter of ring containing plutonium solutions). Those results have been plotted in curves, for several concentrations and for different reflection conditions (outer or inner light water reflector, cadmium screen), H{sub c} and M{sub c} = f (c) (where H{sub c} is the critical height of solution, M{sub c} is the critical mass, c is the plutonium concentration: 42,3 g/lsolutions. - an insulated annular cylinder 500 x 200: incomplete results are published the experiments on this cylinder being unfinished to the date of this present report publication. On this miscellaneous results, we have following informations know: - Screen effect of light water in central hole.

Pericellular oxygen monitoring with integrated sensor chips for reproducible cell culture experiments.

2014-04-01

Here we present an application, in two tumour cell lines, based on the Sensing Cell Culture Flask system as a cell culture monitoring tool for pericellular oxygen sensing. T-47D (human breast cancer) and T98G (human brain cancer) cells were cultured either in atmospheric air or in a glove-box set at 4% oxygen, in both cases with 5% CO2 in the gas phase. Pericellular oxygen tension was measured with the help of an integrated sensor chip comprising oxygen sensor arrays. Obtained results illustrate variation of pericellular oxygen tension in attached cells covered by stagnant medium. Independent of incubation conditions, low pericellular oxygen concentration levels, usually associated with hypoxia, were found in dense cell cultures. Respiration alone brought pericellular oxygen concentration down to levels which could activate hypoxia-sensing regulatory processes in cultures believed to be aerobic. Cells in culture believed to experience conditions of mild hypoxia may, in reality, experience severe hypoxia. This would lead to incorrect assumptions and suggests that pericellular oxygen concentration readings are of great importance to obtain reproducible results when dealing with hypoxic and normoxic (aerobic) incubation conditions. The Sensing Cell Culture Flask system allows continuous monitoring of pericellular oxygen concentration with outstanding long-term stability and no need for recalibration during cell culture experiments. The sensor is integrated into the flask bottom, thus in direct contact with attached cells. No additional equipment needs to be inserted into the flask during culturing. Transparency of the electrochemical sensor chip allows optical inspection of cells attached on top of the sensor. © 2014 John Wiley & Sons Ltd.

Development of a Continuous Phytoplankton Culture System for Ocean Acidification Experiments

Directory of Open Access Journals (Sweden)

Cathryn Wynn-Edwards

2014-06-01

Full Text Available Around one third of all anthropogenic CO2 emissions have been absorbed by the oceans, causing changes in seawater pH and carbonate chemistry. These changes have the potential to affect phytoplankton, which are critically important for marine food webs and the global carbon cycle. However, our current knowledge of how phytoplankton will respond to these changes is limited to a few laboratory and mesocosm experiments. Long-term experiments are needed to determine the vulnerability of phytoplankton to enhanced pCO2. Maintaining phytoplankton cultures in exponential growth for extended periods of time is logistically difficult and labour intensive. Here we describe a continuous culture system that greatly reduces the time required to maintain phytoplankton cultures, and minimises variation in experimental pCO2 treatments over time. This system is simple, relatively cheap, flexible, and allows long-term experiments to be performed to further our understanding of chronic responses and adaptation by phytoplankton species to future ocean acidification.

Subjective experience of architectural objects: A cross-cultural study

2016-01-01

Full Text Available The purpose of the present study was to compare Serbian and Japanese participants in their subjective experience of Serbian and Japanese architectural objects. Subjective experience was operationalized through the ratings on the bipolar scales (e.g. pleasant-unpleasant. In the Preliminary study 1, a set of twelve rating scales was generated. In the Preliminary study 2 twelve Serbian and twelve Japanese architectural objects were specified. In the main experiment two groups of participants, twenty-one Serbian and twenty Japanese, rated twelve Serbian and twelve Japanese objects. A factor analysis extracted three dimensions of subjective experience: Beauty, Firmness and Fullness. Analysis of variance have shown that both Serbian and Japanese participants agreed that Japanese architectural objects looked more beautiful and firmer than Serbian objects. These finding is generally in line with perceptualist hypothesis that stimulus constraints are more effective than culture. However, interactions revealed some cultural differences that are consistent with culturalist hypothesis: compared to Serbian participants, Japanese participants rated Japanese architectural objects as more beautiful, whereas, compared to Japanese, Serbian participants rated Serbian objects as less fragile and emptier than Japanese objects. Generaly, our study have shown that Serbian (Western and Japanese (Eastern participants show general similarity in their subjective experience of architectural objects.

The Department of Energy's Consolidated Fuel Reprocessing Program has as a goal the design of nuclear fuel reprocessing equipment. In order to validate computer codes used for criticality analyses in the design of such equipment, k-effectives have been calculated for several U + Pu nitrate solution critical experiments. As of January 1981, descriptions of 45 unpoisoned, U + Pu solution experiments were available in the open literature. Twelve of these experiments were performed with solutions which have physical characteristics typical of dissolved, light water reactor fuel. This paper contains a discussion of these twelve experiments, a review of the calculational procedure used to determine k-effectives, and the results of the calculations

Developing leaders' strategic thinking through global work experience: the moderating role of cultural distance.

To respond to the challenge of how organizations can develop leaders who can think strategically, we investigate the relation of leaders' global work experiences--that is, those experiences that require the role incumbent to transcend national boundaries--to their competency in strategic thinking. We further examine whether leaders' exposure to a country whose culture is quite distinct from the culture of their own country (i.e., one that is culturally distant) moderates these relationships. Our analyses of 231 upper level leaders reveals that the time they have spent in global work experiences positively relates to their strategic thinking competency, particularly for leaders who have had exposure to a more culturally distant country. We discuss these findings in light of the research on international work experiences and leader development. PsycINFO Database Record (c) 2014 APA, all rights reserved.

Critical experiments on low enriched uranyl nitrate solution with STACY

International Nuclear Information System (INIS)

Miyoshi, Yoshinori

1996-01-01

As the STACY started steady operations, systematic criticality data on low enriched uranyl nitrate solution system could be accumulated. Main experimental parameters for the cylindrical tank of 60 cm in diameter were uranium concentration and the reflector condition. Basic data on a simple geometry will be helpful for the validation of the standard criticality safety codes, and for evaluating the safety margin included in the criticality designs. Experiments on the reactivity effects of structural materials such as borated concrete and polyethylene are on schedule next year as the second series of experiments using 10 wt% enriched uranyl solution. Furthermore, neutron interacting experiments with two slab tanks will be performed to investigate the fundamental properties of neutron interaction effects between core tanks. These data will be useful for making more reasonable calculation models and for evaluating the safety margin in the criticality designs for the multiple unit system. (J.P.N.)

After two years of LHC data taking, processing and analysis and with numerous changes in computing technology, a number of aspects of the experiments' computing, as well as WLCG deployment and operations, need to evolve. As part of the activities of the Experiment Support group in CERN's IT department, and reinforced by effort from the EGI-InSPIRE project, we present work aimed at common solutions across all LHC experiments. Such solutions allow us not only to optimize development manpower but also offer lower long-term maintenance and support costs. The main areas cover Distributed Data Management, Data Analysis, Monitoring and the LCG Persistency Framework. Specific tools have been developed including the HammerCloud framework, automated services for data placement, data cleaning and data integrity (such as the data popularity service for CMS, the common Victor cleaning agent for ATLAS and CMS and tools for catalogue/storage consistency), the Dashboard Monitoring framework (job monitoring, data management m...

What about False Insights? Deconstructing the Aha! Experience along Its Multiple Dimensions for Correct and Incorrect Solutions Separately

Science.gov (United States)

Danek, Amory H.; Wiley, Jennifer

2017-01-01

The subjective Aha! experience that problem solvers often report when they find a solution has been taken as a marker for insight. If Aha! is closely linked to insightful solution processes, then theoretically, an Aha! should only be experienced when the correct solution is found. However, little work has explored whether the Aha! experience can also accompany incorrect solutions (“false insights”). Similarly, although the Aha! experience is not a unitary construct, little work has explored the different dimensions that have been proposed as its constituents. To address these gaps in the literature, 70 participants were presented with a set of difficult problems (37 magic tricks), and rated each of their solutions for Aha! as well as with regard to Suddenness in the emergence of the solution, Certainty of being correct, Surprise, Pleasure, Relief, and Drive. Solution times were also used as predictors for the Aha! experience. This study reports three main findings: First, false insights exist. Second, the Aha! experience is multidimensional and consists of the key components Pleasure, Suddenness and Certainty. Third, although Aha! experiences for correct and incorrect solutions share these three common dimensions, they are also experienced differently with regard to magnitude and quality, with correct solutions emerging faster, leading to stronger Aha! experiences, and higher ratings of Pleasure, Suddenness, and Certainty. Solution correctness proffered a slightly different emotional coloring to the Aha! experience, with the additional perception of Relief for correct solutions, and Surprise for incorrect ones. These results cast some doubt on the assumption that the occurrence of an Aha! experience can serve as a definitive signal that a true insight has taken place. On the other hand, the quantitative and qualitative differences in the experience of correct and incorrect solutions demonstrate that the Aha! experience is not a mere epiphenomenon. Strong Aha

Constantine, Madonna G; Kindaichi, Mai; Okazaki, Sumie; Gainor, Kathy A; Baden, Amanda L

2005-05-01

This qualitative study explored the cultural adjustment experiences of 15 Asian Indian, Japanese, Korean, and Vietnamese international college women through semistructured interviews. By using consensual qualitative research methodology (C. E. Hill, B. J. Thompson, & E. N. Williams, 1997), 6 primary domains or themes related to these women's cultural adjustment experiences were identified via data analysis: their feelings and thoughts about living in the United States, perceived differences between their country of origin and the United States, their English language acquisition and use, their prejudicial or discriminatory experiences in the United States, their peer and family networks, and their strategies for coping with cultural adjustment problems. Implications of the findings for mental health practice are discussed. Copyright (c) 2005 APA, all rights reserved.

Cultural differences in emotion regulation during self-reflection on negative personal experiences.

Science.gov (United States)

Tsai, William; Lau, Anna S

2013-01-01

Reflecting on negative personal experiences has implications for mood that may vary as a function of specific domains (e.g., achievement vs. interpersonal) and cultural orientation (e.g., interdependence vs. independence). This study investigated cultural differences in the social-cognitive and affective processes undertaken as Easterners and Westerners reflected on negative interpersonal and performance experiences. One hundred Asian Americans and 92 European-American college students were randomly assigned to one of three conditions: interpersonal rejection, achievement failure, or a control condition. Results revealed that Asian Americans experienced greater distress than European Americans after self-reflecting over a failed interpersonal experience, suggesting cultural sensitivity in the relational domain. Consistent with theoretical predictions, analysis of the social cognitive and affective processes that participants engaged in during self-reflection provided some evidence that self-enhancement may buffer distress for European Americans, while emotion suppression may be adaptive for Asian Americans.

Omu, Onutobor; Reynolds, Frances

2012-01-01

The aim of this study was to investigate the perceptions of health professionals who treat stroke patients in Kuwait regarding cultural influences on the experience of stroke and rehabilitation in Kuwait. Health professionals interviewed were from a variety of cultural backgrounds thus providing an opportunity to investigate how they perceived the influence of culture on stroke recovery and rehabilitation in Kuwait. Semi-structured interviews were carried out with 12 health professionals with current/recent stroke rehabilitation experience in Kuwait, followed by thematic analysis of the verbatim transcripts. The health professionals identified several features of the Kuwaiti culture that they believed affected the experiences of stroke patients. These were religious beliefs, family involvement, limited education and public information about stroke, prevailing negative attitudes toward stroke, access to finances for private treatment, social stigma and the public invisibility of disabled people, difficulties identifying meaningful goals for rehabilitation, and an acceptance of dependency linked with the widespread presence of maids and other paid assistants in most Kuwaiti homes. To offer culturally sensitive care, these issues should be taken into account during the rehabilitation of Kuwaiti stroke patients in their home country and elsewhere.

The paper presents the main results of several sets of critical experiments with two interacting similar slab tanks filled with aqueous solution of uranyl nitrate with uranium of 90% enrichment. These experiments were carried out at the RF-GS facility, Obninsk, Russia. Tanks with the thickness of 15 cm, width of 100 cm and height of 120 cm were used in these experiments. The experiments were conducted with partitions made of concrete, brick, polyethylene, cadmium, borated polyethylene. Consideration was given to the dependence of critical volume in each tank on the distance between the tanks and on the partition thickness. The tanks were filled with solutions of highly enriched uranium with its concentrations of 75 g/L and 250 g/L. Critical experiments were analysed with the MCNP 4A code based on the Monte-Carlo method and with the ENDF/B-V library. (author)

Park, Elyse R; Betancourt, Joseph R; Kim, Minah K; Maina, Angela W; Blumenthal, David; Weissman, Joel S

2005-09-01

An Institute of Medicine report issued in 2002 cited cross-cultural training as a mechanism to address racial and ethnic disparities in health care, but little is known about residents' training and capabilities to provide quality care to diverse populations. This article explores a select group of residents' perceptions of their preparedness to deliver quality care to diverse populations. Seven focus groups and ten individual interviews were conducted with 68 residents in locations nationwide. Qualitative analysis of focus-group and individual interview transcripts was performed to assess residents' perceptions of (1) preparedness to deliver care to diverse patients; (2) educational climate; and (3) training experiences. Most residents in this study noted the importance of cross-cultural care yet reported little formal training in this area. Residents wanted more formal training yet expressed concern that culture-specific training could lead to stereotyping. Most residents had developed ad hoc, informal skills to care for diverse patients. Although residents perceived institutional endorsement, they sensed it was a low priority due to lack of time and resources. Residents in this study reported receiving mixed messages about cross-cultural care. They were told it is important, yet they received little formal training and did not have time to treat diverse patients in a culturally sensitive manner. As a result, many developed coping behaviors rather than skills based on formally taught best practices. Training environments need to increase training to enhance residents' preparedness to deliver high-quality cross-cultural care if the medical profession is to achieve the goals set by the Institute of Medicine.

Christian Spiritual Experience as a Model of a Culture of Dialogue

Directory of Open Access Journals (Sweden)

Rybicki Adam

2016-12-01

Full Text Available A space for dialogue between people and the cultures is a focus of this article. To start with, the biblical basis for analysing spiritual experience is presented, followed by the components of Christian spiritual-religious experience. It is also explored whether it is possible to cross-reference the said components with the culture of dialogue. A particular focus is made on the spirituality of encounter and mysticism that leads to a conclusion that a reliable and continuously deepening reflection on Christian spirituality shows its value not only on a “vertical” (upright plane, i.e. a dialogue with God, but also on a horizontal, flat plane. It shapes the overall attitude of a person, both towards other people and towards themselves, as well as towards the world around them. Certain elements may play a major role in shaping the culture of dialogue between people and the communities of people. These elements are: relational character, desire of getting to know “the other you”, emphasizing the dignity of “the other you”, mutual respect, shared search for and acceptance of the truth and a communal dimension (communion. The ethical aspects of spiritual experience – including a mystical experience – such as conscience, virtue or value, have also been regarded because the ethical elements play a very important role in the dialogue of people and communities.

Transcultural healthcare immersion: a unique interprofessional experience poised to influence collaborative practice in cultural settings.

Science.gov (United States)

Morton, Jennifer

2012-01-01

This paper describes a model for interprofessional and transcultural learning established by the author and supported by the University of New England and Ghana Health Mission, Inc. The model for interprofessional immersion in cultural settings represents a guiding framework predicated on a conceptual "brick and mortar" process for building cultural proficiency among individuals and within teams. It encompasses social, clinical and behavioral components (brick) and personal desire, cultural humility and values (mortar). The ``bounty'' aspect of the model is achieved by way of successful student learning outcomes, positive interprofessional and community-based collaborations, and finally, and to be measured over time, favorable patient and population (programmatic) outcomes. In partnership with the Ghana Health Mission, Inc and local community health workers, students and faculty from a range of health professions took part in a cultural-clinical experience known as Transcultural Immersion in Healthcare. The goal of the experience was to advance cultural proficiency and knowledge through intensive cultural immersion. An urban setting in Ghana, located in West Africa served as the setting for this unique experience. The transcultural immersion in healthcare experience achieved its ``bounty'' as seen in the enhanced cultural proficiency of students and faculty, seamless interprofessional communication and collaboration, and provision of primary care and related services to patients and the Ghanaian community. Future research is in development to test the Model for Interprofessional Immersion in Cultural Settings (MIICS) in a variety of other settings and with a cross section of health disciplines.

Diaz, V A; Mainous, A G; Pope, C

2007-02-01

In spite of the high prevalence of obesity in the Latino population, there is limited recent information that can be used by health-care providers to develop culturally appropriate weight loss strategies for this population. Therefore, we describe weight loss experiences, attitudes and barriers in overweight Latino adults. Qualitative study using focus group methodology. Twenty-one overweight adults (body mass index >/=25, age >/=20 years) self-identified as Latinos. Subjects participated in one of three focus groups. Reccurring themes within group discussions were identified by three independent investigators, one who was ethnicity concordant. Themes included the presence of mixed messages when determining one's appropriate weight, with participants' desire to lose weight to be healthy (based on professional advice and personal experience) conflicting with the cultural idea that being overweight is healthy. Participants described discordance when adapting to the mainstream, leading to the loss of healthy traditional habits. Participants expressed interest in weight loss and familiarity with dieting and weight loss interventions. They desired culturally appropriate nutrition education and reassurance regarding healthy dieting from health-care providers. The importance of interactions with peers during education was another relevant theme, and participants were overwhelmingly positive about group education. To improve health promotion for Latinos, cultural factors distinctive to this underserved population, and barriers they articulate, should be considered when developing weight loss interventions.

Cultural dissonance among generations: a solution-focused approach with East Asian elders and their families.

Science.gov (United States)

Lee, Mo Yee; Mjelde-Mossey, LeeAnn

2004-10-01

In traditional East Asian cultures, high value is assigned to family harmony and filial piety coupled with the expectation that elders will be honored and obeyed. A lifetime of such expectations shapes how elders perceive their role and status in the family. Problems can arise when younger, less traditional, generations do not share these expectations. This article describes a solution-focused approach that facilitates the family in creating a beneficial harmony in situations of cultural dissonance. Family members are empowered to draw on personal strengths in which multiple worldviews and values of individual members are recognized, incorporated, and negotiated.

A water-cooling solution for PC-racks of the LHC experiments

CERN Document Server

Vannerem, P

2004-01-01

With ever increasing power consumption and heat dissipation of todays CPUs, cooling of rack-mounted PCs is an issue for the future online farms of the LHC experiments. In order to investigate the viability of a water-cooling solution, a prototype PC-farm rack has been equipped with a commercially available retrofitted heat exchanger. The project has been carried out as a collaboration of the four LHC experiments and the PH-ESS group . This note reports on the results of a series of cooling and power measurements of the prototype rack with configurations of 30 to 48 PCs. The cooling performance of the rack-cooler is found to be adequate; it extracts the heat dissipated by the CPUs efficiently into the cooling water. Hence, the closed PC rack transfers almost no heat into the room. The measurements and the failure tests show that the rack-cooler concept is a viable solution for the future PC farms of the LHC experiments.

Skin vitrification is a promising and alternative tool for the conservation of biodiversity, especially for wild mammals, such as collared peccaries. Several factors can affect the success of this procedure, such as the cryoprotectant solution used. Therefore, this study was carried out to compare the efficiency of various vitrification solutions for recovery of viable cells after in vitro culture of cryopreserved skin tissues derived from the collared peccary, aiming to study the application in biobanking, where cellular use is not immediately required. Then, Dulbecco's modified Eagle's medium (DMEM) composed of 2.2 g/L sodium bicarbonate and 10% fetal bovine serum (FBS) was supplemented with 3.0 M ethylene glycol (EG) or 3.0 M dimethyl sulfoxide (DMSO) or 1.5 M EG plus 1.5 M DMSO with or without sucrose (SUC; 0.25 M) to produce six solutions for solid-surface vitrification. After warming, skin tissues were cultured in vitro and recovered cells were analyzed for morphology, adhesion, subconfluence, and proliferative activity for developing the growth curve and determining the population doubling time (PDT), and viability by Trypan Blue. The vitrification did not alter the ability of the tissues to adhere to the culture dish, as well as the day of all explants with cell growth, subconfluence samples, subconfluence total time, and PDT (p > 0.05). Moreover, independent of the cryoprotectant solution used, the vitrification altered the day of all attached explants (p  0.05). Additionally, for viability after the third passage, only the EG-SUC group maintained the cell quality (88.3%), when compared with the nonvitrified (97.8%, p > 0.05). In conclusion, DMEM with 10% FBS, 3.0 M EG, and 0.25 M sucrose was the most efficient solution for vitrifying collared peccary skin tissues, leading to the in vitro culture of viable cells.

Almutairi, Adel F; McCarthy, Alexandra; Gardner, Glenn E

2015-01-01

In Saudi Arabia, the health system is mainly staffed by expatriate nurses from different cultural and linguistic backgrounds. Given the potential risks this situation poses for patient care, it is important to understand how cultural diversity can be effectively managed in this multicultural environment. The purpose of this study was to explore notions of cultural competence with non-Saudi Arabian nurses working in a major hospital in Saudi Arabia. Face-to-face, audio-recorded, semistructured interviews were conducted with 24 non-Saudi Arabian nurses. Deductive data collection and analysis were undertaken drawing on Campinha-Bacote's cultural competence model. The data that could not be explained by this model were coded and analyzed inductively. Nurses within this culturally diverse environment struggled with the notion of cultural competence in terms of each other's cultural expectations and those of the dominant Saudi culture. The study also addressed the limitations of Campinha-Bacote's model, which did not account for all of the nurses' experiences. Subsequent inductive analysis yielded important themes that more fully explained the nurses' experiences in this environment. The findings can inform policy, professional education, and practice in the multicultural Saudi setting. © The Author(s) 2014.

Microfluidic model experiments on the injectability of monoclonal antibody solutions

2017-11-01

Autoinjection devices that allow patients to self-administer medicine are becoming used more frequently; however, this advance comes with an increased need for precision in the injection process. The rare occurrence of protein aggregates in solutions of monoclonal antibodies constitutes a threat to the reliability of such devices. Here we study the flow of protein solutions containing aggregates in microfluidic model systems, mimicking injection devices, to gain fundamental understanding of the catastrophic clogging of constrictions of given size. We form aggregates by mechanically shaking or heating antibody solutions and then inject these solutions into microfluidic channels with varying types of constrictions. Geometrical clogging occurs when aggregates reach the size of the constriction and can in some cases be undone by increasing the applied pressure. We perform systematic experiments varying the relative aggregate size and the flow rate or applied pressure. The mechanical deformation of aggregates during their passage through constrictions is investigated to gain a better understanding of the clogging and unclogging mechanisms.

Residual biomass from hydroponic culture of sweetpotato [Ipomoea batatas (L.) Lam.] was degraded using natural bacterial soil isolates. Sweetpotato was grown for 120 days in hydroponic culture with a nutrient solution comprised of a ratio of 80% modified half Hoagland solution to 20% filtered effluent from an aerobic starch hydrolysis bioreactor. The phytotoxicity of the effluent was assayed with `Waldmann's Green' lettuce (Lactuca sativa L.) and the ratio selected after a 60-day bioassay using sweetpotato plants propagated vegetatively from cuttings. Controlled environment chamber experiments were conducted to investigate the impact of filtrate from biological treatment of crop residue on growth and storage root production with plants grown in a modified half Hoagland solution. Incorporation of bioreactor effluent, reduced storage root yield of `Georgia Jet' sweetpotato but the decrease was not statistically significant when compared with yield for plants cultured in a modified half Hoagland solution without filtrate. However, yield of `TU-82-155' sweetpotato was significantly reduced when grown in a modified half Hoagland solution into which filtered effluent had been incorporated. Total biomass was significantly reduced for both sweetpotato cultivars when grown in bioreactor effluent. The leaf area and dry matter accumulation were significantly (P < 0.05) reduced for both cultivars when grown in solution culture containing 20% filtered effluent.

The aim of the present research was to develop a low cost and easy to perform vitrification method for in vitro-produced cattle embryos. Effect of container material was evaluated (plastic straw compared to glass capillary, experiment 1), two volume sample (1 compared to 0.5 microL, experiment 2) and warming solution composition medium (Tissue Culture Medium 199 (TCM-199) compared to phosphate buffered saline (PBS), experiment 3) as modifications of the open pulled straw (OPS) system in order to reduce embryo damage caused by exposure to cold. In all experiments, day 7 and expanded blastocysts of cattle were exposed to the vitrification solution 1 for 3 min and 30s in solution 2. After this, embryos were placed in a droplet and loaded in a narrow end container, and immediately submerged into liquid nitrogen. For warming, vitrified embryos were plunged into warming solution 1 for 3 min, and transferred into warming solution 2 for 1 min. Fresh embryos kept in culture were used as control group. Hatching rates were recorded in all cases at day 13. In experiment 1 there was no significant effect of container material on hatching rates. Postwarming survival rate of vitrified embryos was lower than control (27.5% plastic straws, 18.9% glass capillary and 80.5% control, Pstraw (OPS) procedure, and that PBS can replace TCM-199 in warming solutions, but lesser hatching rates should be expected.

Cultural affordances and emotional experience: socially engaging and disengaging emotions in Japan and the United States.

Kitayama, Shinobu; Mesquita, Batja; Karasawa, Mayumi

2006-11-01

The authors hypothesized that whereas Japanese culture encourages socially engaging emotions (e.g., friendly feelings and guilt), North American culture fosters socially disengaging emotions (e.g., pride and anger). In two cross-cultural studies, the authors measured engaging and disengaging emotions repeatedly over different social situations and found support for this hypothesis. As predicted, Japanese showed a pervasive tendency to reportedly experience engaging emotions more strongly than they experienced disengaging emotions, but Americans showed a reversed tendency. Moreover, as also predicted, Japanese subjective well-being (i.e., the experience of general positive feelings) was more closely associated with the experience of engaging positive emotions than with that of disengaging emotions. Americans tended to show the reversed pattern. The established cultural differences in the patterns of emotion suggest the consistent and systematic cultural shaping of emotion over time.

Factors influencing the adoption of self-management solutions: an interpretive synthesis of the literature on stakeholder experiences.

In a research context, self-management solutions, which may range from simple book diaries to complex telehealth packages, designed to facilitate patients in managing their long-term conditions, have often shown cost-effectiveness, but their implementation in practice has frequently been challenging. We conducted an interpretive qualitative synthesis of relevant articles identified through systematic searches of bibliographic databases in July 2014. We searched PubMed (Medline/NLM), Web of Science, LISTA (EBSCO), CINAHL, Embase and PsycINFO. Coding and analysis was inductive, using the framework method to code and to categorise themes. We took a sensemaking approach to the interpretation of findings. Fifty-eight articles were selected for synthesis. Results showed that during adoption, factors identified as facilitators by some were experienced as barriers by others, and facilitators could change to barriers for the same adopter, depending on how adopters rationalise the solutions within their context when making decisions about (retaining) adoption. Sometimes, when adopters saw and experienced benefits of a solution, they continued using the solution but changed their minds when they could no longer see the benefits. Thus, adopters placed a positive value on the solution if they could constructively rationalise it (which increased adoption) and attached a negative rationale (decreasing adoption) if the solution did not meet their expectations. Key factors that influenced the way adopters rationalised the solutions consisted of costs and the added value of the solution to them and moral, social, motivational and cultural factors. Considering 'barriers' and 'facilitators' for implementation may be too simplistic. Implementers could instead iteratively re-evaluate how potential facilitators and barriers are being experienced by adopters throughout the implementation process, to help adopters to retain constructive evaluations of the solution. Implementers need to pay

, including: • Self evaluation of safety culture; • Questioning the staff; • Independent audits of safety culture. NAEC “Energoatom” seeks to take into account international experience, and to participate in conferences (such as this one), seminars and workshops held under the auspices of the IAEA, as well as to follow the guidelines and standards of the IAEA in the organization of activities to improve the safety culture. Other sources of international experience in this field are the EU-funded projects of “soft” assistance and guidance of other authorised international nuclear industry organizations such as WANO. In this regard, it should be mentioned WANO guidance document GL 2002-02 “Principles of effective personnel organization” that identifies five fundamental principles relating to human factors, and important for the development of a sustainable safety culture in the organization: • Even the best experts make mistakes; • A situation fraught with errors is predictable, manageable and preventable; • Human behavior is determined by organizational processes and values; • Highest efficiency operation is achieved through the promotion and support; • Violations can be avoided by understanding the causes of errors and implementing lessons learned. Within the framework of the international programs of EC “soft” aid in recent years, the projects that contribute to the development of a safety culture in the NAEC “Energoatom” have been either carried out or are ongoing. These projects include the solution of certain problems (for example, in the area of human factor—the task of “no punishment for error” approach establishment), as well as more common tasks of improving overall safety culture, such as: • Implementation of programs to inform senior staff and management, including the essential features needed to create a strong culture of safety; creating conditions for the improvement of the organizational and managerial impact on the

Recrystallization Experiments of Pyrite From Circulating Hydrothermal Solution by Thermal Convection

Science.gov (United States)

Tanaka, K.; Isobe, H.

2005-12-01

Pyrite is one of the most common accessory minerals in many rocks and generally occurs in hydrothermal deposit. However, pyrite morphology and association with other sulfide minerals is not well known with respect to the solution condition, especially with the hydrothermal solution under circulation. In this study, recrystallization experiments of pyrite from circulating hydrothermal solution by thermal convection were carried out. A rectangular circuit (42.6 cm by 17.3 cm) of SUS316 pressure tubing with 5 mm in inner diameter was used as a reaction vessel. The volume of the circuit is approximately 24 ml. Long sides of the rectangular circuit were held to be 20 degrees inclination. One of the long sides was heated by an electric furnace. Solution in the circuit evaporates in the high temperature tubing and the vapor condenses in room temperature tubing. The solution backs to the bottom of the high temperature tubing. Thus, thermal convection of the solution produces circulation in the circuit. Starting material was filled in the high temperature tubing. The lower half was filled with mixture of 2 g of powdered natural pyrite and 4 g of quartz grains. The upper half was filled with quartz grains only. 9 ml of 5 mol/l NH4Cl solution was sealed in the circuit with the starting material. Temperature gradient of the sample was monitored by 6 thermocouples. Maximum temperature was controlled at 350°C. Experimental durations are 3, 5, 10 and 30 days. After the experiments, the run products are fixed with resin and cut every 2 cm. Thin sections of vertical cross-sections are made and observed by microscope and SEM. Tiny pyrite crystals occurred at the upper outside of the furnace, where temperature should be much lower than 200°C. In the lower half of the starting material, pyrite decomposed and pyrrhotite formed around pyrite grains. At higher temperature area, pyrite decomposition and pyrrhotite formation is remarkable.

Finding meaning in first episode psychosis: experience, agency, and the cultural repertoire.

Science.gov (United States)

Larsen, John Aggergaard

2004-12-01

The article examines individuals' attempts to generate meaning following their experiences with psychosis. The inquiry is based on a person-centered ethnographic study of a Danish mental health community program for early intervention in schizophrenia and involves longitudinal interviews with 15 of its participants. The article takes an existential anthropological perspective emphasizing agency and cultural phenomenology to investigate how individuals draw on resources from the cultural repertoire to make sense of personally disturbing experiences during their psychosis. It is suggested that the concept of "system of explanation" has advantages over, for example, "illness narrative" and "explanatory model" when demonstrating how some individuals engage in the creative analytic and theory-building work of bricolage, selecting, adding, and combining various systems of explanation. Delusions are equally derived from the cultural repertoire but are constructed as dogmatic explanations that are idiosyncratic to the individual who holds them.

For example, the eye movement strategies used for information extraction during a variety of face processing tasks (e.g., identification and facial expressions of emotion categorization differs across cultural groups. Currently, many of the differences reported in previous studies have asserted that culture itself is responsible for shaping the way we process visual information, yet this has never been directly investigated. In the current study, we assessed the relative contribution of genetic and cultural factors by testing face processing in a population of British Born Chinese (BBC adults using face recognition and expression classification tasks. Contrary to predictions made by the cultural differences framework, the majority of BBC adults deployed ‘Eastern’ eye movement strategies, while approximately 25% of participants displayed ‘Western’ strategies. Furthermore, the cultural eye movement strategies used by individuals were consistent across recognition and expression tasks. These findings suggest that ‘culture’ alone cannot straightforwardly account for diversity in eye movement patterns. Instead a more complex understanding of how the environment and individual experiences can influence the mechanisms that govern visual processing is required.

Highlights: • The surface tensions of MEA/DEA–ionic liquids aqueous solutions were measured. • The experiments were modeled satisfactorily by using a thermodynamic equation. • The temperature dependence of the surface tension was illustrated. • The effects of the mass fractions of MEA/DEA and ionic liquids were demonstrated. - Abstract: The surface tension (γ) of 1-butyl-3-methylimidazolium tetrafluoroborate ([Bmim][BF 4 ])–monoethanolamine (MEA), 1-butyl-3-methylimidazolium bromide ([Bmim][Br])–MEA, [Bmim][BF 4 ]–diethanolamine (DEA) and [Bmim][Br]–DEA aqueous solutions was measured by using the BZY-1 surface tension meter. The temperature ranged from (293.2 to 323.2) K. The mass fraction of amines and ionic liquids (ILS) respectively ranged from 0.15 to 0.30 and 0.05 to 0.10. A thermodynamic equation was proposed to model the surface tension of amines–ILS aqueous solutions and the calculated results agreed well with the experiments. The effects of temperature, mass fraction of amines and ILS on the surface tension were demonstrated on the basis of experiments and calculations

2012-01-01

After two years of LHC data taking, processing and analysis and with numerous changes in computing technology, a number of aspects of the experiments’ computing as well as WLCG deployment and operations need to evolve. As part of the activities of the Experiment Support group in CERN’s IT department, and reinforced by effort from the EGI-InSPIRE project, we present work aimed at common solutions across all LHC experiments. Such solutions allow us not only to optimize development manpower but also offer lower long-term maintenance and support costs. The main areas cover Distributed Data Management, Data Analysis, Monitoring and the LCG Persistency Framework. Specific tools have been developed including the HammerCloud framework, automated services for data placement, data cleaning and data integrity (such as the data popularity service for CMS, the common Victor cleaning agent for ATLAS and CMS and tools for catalogue/storage consistency), the Dashboard Monitoring framework (job monitoring, data management...

Supporting students of diverse cultures and faiths - Experiences from a University perspective.

University of Bedfordshire is a large University with over 24000 students from over 100 countries. The main religions recorded are Christianity, Islam, Hinduism, Buddhism, Jewish and Sikhism amongst others. Around 45% of them do not have any recorded religion. The Mental Health Advisor will come across a wide range of students from different backgrounds each with their own unique presentation of mental health distress. It is well known that people of different communities and cultures experience signs and symptoms of mental distress in different ways. This is very important for clinicians to be aware of the nuances around cultures and traditions in the context of mental illness in order to assist clinicians more accurately diagnose, support and manage them. In an effort to improve diagnosis and care to people of all backgrounds, the 5 th edition of the Diagnosis and Statistical Manual of Mental Disorders (DSM-5) incorporates a greater cultural sensitivity throughout the manual. This includes a reflection of cross-cultural variations in presentations and cultural concepts of distress. The mental Health Advisor is available to help with practical support to assist students to manage their mental health and study. This includes support with an initial assessment, structures support, assisting with making reasonable adjustments under the Equality Act (2010), support students to access Disabled Student's Allowances and reasonable adjustments to enable them to study effectively and achieve their potential and where necessary, making appropriate referrals to internal and/or external services. One of the main roles of the advisor is to support students with mental health difficulties which are impacting on their studies. This support may include anxiety management, motivation, relaxation techniques, study plans and understanding the impact of medication. This paper will look at some of the experiences faced by the mental health advisor and will also reflect on

Characteristics of accumulation and tolerance of cadmium (Cd) in Bidens tripartite L. were investigated to identify Cd-accumulating properties. In this study, pot culture experiment and site sampling experiments were conducted to assess whether this plant is a heavy metal hyperaccumulator or accumulator. The results indicated that the Cd enrichment factor (concentration in plant/soil) and Cd translocation factor (concentration in shoot/root) of B. tripartite was principally >1 in pot culture and concentration gradient experiments. Shoot biomass was not reduced significantly (p -1 , the threshold concentration for a Cd-hyperaccumulator. In the site sampling experiment, B. tripartite also showed Cd-accumulator properties. Based on these results, B. tripartite could be identified as a Cd-accumulator. Thus, B. tripartite should only be considered as a Cd-accumulator.

Learning in the clinical environment of healthcare students plays a significant part in higher education. The greatest challenges for culturally and linguistically diverse healthcare students were found in clinical placements, where differences in language and culture have been shown to cause learning obstacles for students. There has been no systematic review conducted to examine culturally and linguistically diverse healthcare students' experiences of their learning in the clinical environment. This systematic review aims to identify culturally and linguistically diverse healthcare students' experiences of learning in a clinical environment. The search strategy followed the guidelines of the Centre of Reviews and Dissemination. The original studies were identified from seven databases (CINAHL, Medline Ovid, Scopus, Web of Science, Academic Search Premiere, Eric and Cochrane Library) for the period 2000-2014. Two researchers selected studies based on titles, abstracts and full texts using inclusion criteria and assessed the quality of studies independently. Twelve original studies were chosen for the review. The culturally and linguistically diverse healthcare students' learning experiences were divided into three influential aspects of learning in a clinical environment: experiences with implementation processes and provision; experiences with peers and mentors; and experiences with university support and instructions. The main findings indicate that culturally and linguistically diverse healthcare students embarking on clinical placements initially find integration stressful. Implementing the process of learning in a clinical environment requires additional time, well prepared pedagogical orientation, prior cultural and language education, and support for students and clinical staff. Barriers to learning by culturally and linguistically diverse healthcare students were not being recognized and individuals were not considered motivated; learners experienced the

1987-01-01

A homogeneous U-233 uranyl nitrate solution fuelled BeO reflected, low critical mass reactor has been built at the Bhabha Atomic Research Centre, India. Christened PURNIMA II, the reactor was used for the study of the variation of critical mass as a function of fuel solution concentration to determine the minimum critical mass achievable for this geometry. Other experiments performed include the determination of temperature coefficient of reactivity, study of time behaviour of photoneutrons produced due to interaction between decaying U-233 fission product gammas and the beryllium reflector and reactor noise measurements. Besides being the only operational U-233 fuelled reactor at present, PURNIMA II also has the distinction of having attained the lowest critical mass of 397 g of fissile fuel for any operating reactor at the current time. The paper briefly describes the facility and gives an account of the experiments performed and results achieved. (author)

Indigenous cultural contexts for STEM experiences: snow snakes' impact on students and the community

Science.gov (United States)

Miller, Brant G.; Roehrig, Gillian

2018-03-01

Opportunities for American Indian youth to meaningfully engage in school-based science, technology, engineering, and mathematics (STEM) experiences have historically been inadequate. As a consequence, American Indian students perform lower on standardized assessments of science education than their peers. In this article we describe the emergence of meaning for students—as well as their community—resulting from Indigenous culturally-based STEM curriculum that used an American Indian tradition as a focal context. Specifically, the game of snow snakes ( Gooneginebig in Ojibwe) afforded an opportunity for STEM and culturally-based resources to work in unison. A case study research design was used with the bounded case represented by the community associated with the snow snake project. The research question guiding this study was: What forms of culturally relevant meaning do students and the community form as a result of the snow snake game? Results indicate evidence of increased student and community engagement through culturally-based STEM experiences in the form of active participation and the rejuvenation of a traditional game. Implications are discussed for using culturally-based contexts for STEM learning.

Extraordinary experiences in its cultural and theoretical context.

Science.gov (United States)

von Lucadou, Walter; Wald, Franziska

2014-06-01

The growing complexity, opaqueness and specialization of many areas of life and - above all - a booming psychological and esoteric market create the necessity for counselling and advice for individuals who encounter so-called 'paranormal' experiences. These experiences are often interpreted as 'transpersonal' or 'spiritual', depending on the cultural background and religious traditions. The term 'spiritual crisis' has become a fashionable diagnosis with some transpersonal psychotherapists. Paranormal experiences, regardless of their acceptance of academic psychology and psychiatry, are still a taboo subject in society. The Parapsychological Counselling Office in Freiburg is a professional unit with governmental support, which helps individuals to cope with such experiences adequately. The work and responsibilities of the counselling centre are presented. A large collection of cases in the form of letters, which were sent in by individuals wanting to communicate their unusual or extraordinary experiences have been analysed. Some of the results are reported here. Finally, we discuss a special form of 'inexplicable experiences' based on a theoretical model. Its recommendations seem counter-intuitive but are ultimately successful. The model starts from a system-theoretical viewpoint and uses concepts such as complementarity and entanglement of generalized quantum theory (GQT) and the model of pragmatic information (MPI). Since it turned out that individuals who contact the counselling centre also offer their own interpretations and 'explanation', the question arises, how these resources can be used to help clients.

Geoheritage, Geotourism and the Cultural Landscape: Enhancing the Visitor Experience and Promoting Geoconservation

Directory of Open Access Journals (Sweden)

John E. Gordon

2018-04-01

Full Text Available Geotourism spans a range of visitor interests, from the specialist geotourist to the more general visitor. As well as supporting geoconservation outcomes, it provides economic, cultural, relational and social benefits for both visitors and host communities. The interconnections between geoheritage and the cultural components of the landscape have antecedents in concepts of landscape aesthetics in different cultures. These interconnections provide a range of opportunities for enhancing the geotourist experience and promoting geoconservation and geoeducation by means of activities that involve aesthetic and emotional experiences and interpretation through different cultural filters that encourage the rediscovery of a sense of wonder both about the geological stories in the landscape and the human interactions. A cultural ecosystem services framework provides a holistic approach for informing conservation policy, management and planning for geotourism, enabling assessment of multiple benefits and trade-offs for visitors and communities based on the values of the geoheritage assets. Geotourism studies could also benefit from integration of existing theory, conceptual analysis and practice from broader heritage and nature-based tourism and closer collaboration with relevant social sciences. Adhering to sound geoethical practice is an essential part of geotourism, which can also play a role in the promotion of geoethics among the public and professionals.

The Pursuit of Happiness and Its Relationship to the Meta-experience of Emotions and Culture.

Science.gov (United States)

Hofmann, Stefan G

2013-04-01

In this commentary, I provide a brief background of the meta-experience of emotions, the philosophical and psychological literature on happiness, and further discuss the influence of culture on happiness. The meta-experience of emotions implies that there are primary and secondary emotions (i.e., emotions about emotions), similar to the concept of meta-cognitions. Primary and secondary emotions are closely associated with one's cultural background and happiness. Most scholars throughout history believe that happiness per se cannot be taught. However, it is possible to teach practices that lead to the path toward happiness. Promising strategies include loving-kindness and compassion meditation. These strategies are based on Buddhist teachings, which are deeply rooted in a collectivistic culture. This illustrates the close association between emotions, approaches towards happiness, and cultural background.

Cultural Centre, Destination Cultural Offer and Visitor Satisfaction

Directory of Open Access Journals (Sweden)

Benxiang Zeng

2017-10-01

Full Text Available This paper aims to establish the link between tourists’ perceptions on cultural offers and their overall satisfaction, and explore the implication of this link for sustainable tourist destination management. Assessing online customers’ reviews, this study identifies a positive correlation between visitors’ perspectives and experiences at the on-site cultural centre and visitors’ destination satisfaction. It suggests that the on-site cultural centre plays a critical role in building up visitors’ perception on cultural attributes of the destination, and its impact on visitor satisfaction is a double-edged sword. Visitors’ positive perspectives on the cultural centre enhance visitors’ experiences and contribute to their destination satisfaction; however, not only does a negative perspective on their cultural and spiritual experience compromise visitors’ satisfaction, but also subsequent negative online reviews damage the destination image and discourage visitor return/visit. The findings help destination management organisations to better understand visitors’ preference for cultural centres and therefore to improve visitors’ cultural experience. This paper appeals for further study of on-site cultural centres’ role in forming destination cultural attributes, and of social media’s potential in enriching cultural experience.

Galdas, Paul M; Oliffe, John L; Wong, Sabrina T; Ratner, Pamela A; Johnson, Joy L; Kelly, Mary T

2012-01-01

To describe how culture underlies Canadian Punjabi Sikh men's experiences of adopting lifestyle changes following myocardial infarction (MI). Qualitative, interpretive design. In-depth, individual interviews were conducted with 27 Canadian Punjabi Sikh men post-MI. Data were analysed using constant comparative methods. Cultural influences were identified in Punjabi Sikh men's descriptions of their experience of adopting lifestyle changes. Actions related to self-care, rehabilitation and lifestyle change post-MI were embedded in collectivist family and community contexts. Three themes, derived from the data, were found to intertwine with these contexts; they related to food consumption, physical exercise and faith and religion. These findings highlight how collectivist ideals influence Canadian Punjabi Sikh men's adoption of lifestyle changes post-MI. The content and processes by which healthcare providers deliver heart health and rehabilitation to Canadian Punjabi Sikh men might be guided, at least in part, by the collectivist cultural practices underpinning our findings.

Ethical and cultural striving: Lived experiences of minority nurses in dementia care.

Science.gov (United States)

Egede-Nissen, Veslemøy; Sellevold, Gerd Sylvi; Jakobsen, Rita; Sørlie, Venke

2017-09-01

Nursing workforce in Western European health institutions has become more diverse because of immigration and recruitment from Asian, African, and East-European countries. Minority healthcare providers may experience communication problems in interaction with patients and coworkers, and they are likely to experience conflict or uncertainty when confronted with different cultural traditions and values. Persons with dementia are a vulnerable group, and the consequences of their illness challenge the ability to understand and express oneself verbally. The large number of minority healthcare providers in nursing homes underlines the importance to obtain better knowledge about this group's experiences with the care challenges in dementia care units. Can you tell about any challenges in the experiences in the encounter with persons suffering from dementia? Participants and research context: Five minority healthcare providers in a nursing home, in a dementia unit. All guidelines for research ethic were followed. Ethical consideration: The participants were informed that participation was voluntary, and they were guarantied anonymity. We used a qualitative method, conducting individual interviews, using a narrative approach. In the analysis, we applied a phenomenological-hermeneutical method, developed for researching life experiences. One theme and four subthemes: striving to understand the quality of care for persons with dementia. The subthemes: sensitivity to understand the patients' verbal and nonverbal expressions. To understand gratefulness, understand the patient as an adult and autonomous person, and understand the patient as a patient in a nursing home. Challenges comprise both ethical and cultural striving to understand persons with dementia. To care for persons with dementia in an unfamiliar context may be understood as a striving for acting ethically, when at the same time striving to adapt and acculturate to new cultural norms, in order to practice good

Used Fuel Logistics: Decades of Experience with transportation and Interim storage solutions

Energy Technology Data Exchange (ETDEWEB)

Orban, G.; Shelton, C.

2015-07-01

Used fuel inventories are growing worldwide. While some countries have opted for a closed cycle with recycling, numerous countries must expand their interim storage solutions as implementation of permanent repositories is taking more time than foreseen. In both cases transportation capabilities will have to be developed. AREVA TN has an unparalleled expertise with transportation of used fuel. For more than 50 years AREVA TN has safely shipped more than 7,000 used fuel transport casks. The transportation model that was initially developed in the 1970s has been adapted and enhanced over the years to meet more restrictive regulatory requirements and evolving customer needs, and to address public concerns. The numerous “lessons learned” have offered data and guidance that have allowed for also efficient and consistent improvement over the decades. AREVA TN has also an extensive experience with interim dry storage solutions in many countries on-site but also is working with partners to developed consolidated interim storage facility. Both expertise with storage and transportation contribute to safe, secure and smooth continuity of the operations. This paper will describe decades of experience with a very successful transportation program as well as interim storage solutions. (Author)

Forming insights: assessment of the occupational therapy practice in a cultural context from experience with indigenous people

Directory of Open Access Journals (Sweden)

Maria Daniela Corrêa de Macedo

2016-01-01

Full Text Available This article is the result of a reflection process on the issue of occupational therapy and culture through analysis of practical experiences of a extension project. It aimed to increase knowledge and reflections of occupational therapy and its technical actions in cultural contexts from the perspective of ethnicity issues. It is a documental and qualitative research was aiming to report the experience of students and an occupational therapist, obtained through their written reports between 2012 and 2014. Data were analyzed using the categorizations proposed by Bardin. The categories of analysis found are related to technical activities in occupational therapy, namely: cultural and ethnic action. The results showed that, in the experiences with the Guarani community, there are already significant and consolidated actions of occupational therapy in cultural contexts. The technical actions already performed confirm the relevance of the occupational therapist role in the cultural context and in the ethnicity context. These practices are, in turn, relevant for the production of knowledge, the theoretical and methodological scope and professional training in social and cultural contexts of occupational therapy. It is emphasized that technical procedures coherent with the ethnicity issues in a joint relationship, articulated by cultural mediation, can strengthen human doings and identity claims.

Solution High-Energy Burst Assembly (SHEBA) results from subprompt critical experiments with uranyl fluoride fuel

International Nuclear Information System (INIS)

Cappiello, C.C.; Butterfield, K.B.; Sanchez, R.G.

1997-10-01

The Solution High-Energy Burst Assembly (SHEBA) was originally constructed during 1980 and was designed to be a clean free-field geometry, right-circular, cylindrically symmetric critical assembly employing U(5%)O 2 F 2 solution as fuel. A second version of SHEBA, employing the same fuel but equipped with a fuel pump and shielding pit, was commissioned in 1993. This report includes data and operating experience for the 1993 SHEBA only. Solution-fueled benchmark work focused on the development of experimental measurements of the characterization of SHEBA; a summary of the results are given. A description of the system and the experimental results are given in some detail in the report. Experiments were designed to: (1) study the behavior of nuclear excursions in a low-enrichment solution, (2) evaluate accidental criticality alarm detectors for fuel-processing facilities, (3) provide radiation spectra and dose measurements to benchmark radiation transport calculations on a low-enrichment solution system similar to centrifuge enrichment plants, and (4) provide radiation fields to calibrate personnel dosimetry. 15 refs., 37 figs., 10 tabs

Safety goals and safety culture opening plenary. 1. WANO's Role in Maintaining and Improving Safety Culture

International Nuclear Information System (INIS)

Tsutsumi, Ryosuke

2001-01-01

Over the past several years, operators of the world's nuclear plants have compiled an increasingly impressive record of operational performance. Among the many factors that have led to this improvement are the unprecedented cooperation and information exchange among the world's nuclear operators. This paper presents the World Association of Nuclear Operators (WANO) operating experience program and WANO peer review program as examples of the kinds of interaction that are occurring around the globe to maintain and improve the nuclear safety culture. In addition, some unique features of WANO are discussed. WANO has established four programs to help its members communicate effectively with each other. These include the exchange of operating experiences, voluntary peer reviews, professional and technical development, and technical support and exchange. The operating experience program alerts members to events that have occurred at other NPPs and enables members to take appropriate actions to prevent event recurrence. When an event occurs at a plant, management at that plant analyses the event and completes an event report, which is then sent to the WANO regional center to which the plant belongs. After a regional center review and necessary iteration, the report is posted onto the WANO Web site to make it available to all WANO members. By the end of 2000, more than 1500 event reports had been posted. The WANO Peer Review Program is a unique opportunity for members to learn and share the best worldwide insights into safe and reliable nuclear operations. The peer review program has become one of WANO's most important activities containing all essential elements of WANO's mission. A WANO peer review team consists of 15 to 16 people with NPP experience; most team members are from countries outside the one that they are visiting. These teams of peers from plants around the world visit host plants upon request to identify strengths and areas for improvement, with a strong

Ethnic Swedish parents' experiences of minority ethnic nurses' cultural competence in Swedish paediatric care.

Science.gov (United States)

Tavallali, Azar G; Kabir, Zarina Nahar; Jirwe, Maria

2014-06-01

Sweden has a population of a little more than 9.4 million. The rapid growth of immigration in Sweden has resulted in an increased number of minority ethnic patients and minority ethnic nurses in the Swedish healthcare system. This also applies to paediatric care. The purpose of this study was to explore how parents with ethnic Swedish backgrounds experience minority ethnic nurses' cultural competence and the care the nurses provide in a Swedish paediatric care context. This exploratory qualitative study is of 14 parents with an ethnic Swedish background whose child was in a ward at a children's hospital in Stockholm County Council. Data were collected using semi-structured interviews to identify parents' perceptions and experiences of minority ethnic nurses' cultural competence. The interviews were analysed by qualitative content analysis. The analyses of the interviews led to four main categories: influence of nurses' ethnicity; significance of cross-cultural communication; cross-cultural skills; and the importance of nursing education. Nurses' ethnicity did not have much impact on parents' satisfaction with their child's care. The parents attached importance to nurses' language skills and to their adaptation and awareness of Swedish culture. They also attached weight to nurses' professional knowledge and personal attributes. The role of nursing education to increase nurses' cultural awareness was highlighted too. © 2013 Nordic College of Caring Science.

Culture experiments on conductive polymers

International Nuclear Information System (INIS)

Onoda, Mitsuyoshi

2012-01-01

Fibroblast L929 and myoblast C2C12 cells of the mouse connective tissue origin were sown on the surface of conductive polymer films (polypyrrole, PPy and poly(3,4-ethylenedioxythiophene), PEDOT) in the cell culture medium, and the proliferative process of these cells was observed. Without changing the form, fibroblast L929 and myoblast C2C12 cells were observed to proliferate almost similarly to the cell which cultured on a dish on the market and to maintain compatibility. In other word, it has been understood these two kinds of conductive polymers used in this study, the PEDOT films maintain the secretion function of the cell cultured on the surface of these polymers. Therefore, the PPy- and the PEDOT-coated electrode suggested the possibility usable as a nerve stimulation electrode with biocompatibility, because these polymers were effective to culture the cell.

Because of worldwide migration, the healthcare staff in general as well as in paedi"atric care specifically is challenged increasingly by people from various ethnic backgrounds. The challenge is related to providing culturally competent care and effectively communicating with people from diverse cultural and ethnic backgrounds who have different health beliefs, practices, values and languages. This also applies to the Swedish society and to Swedish paediatric care. The purpose of this study was to describe the expectations and experiences of cross-cultural care encounters among minority ethnic parents in Swedish paediatric care. A qualitative design was used in the study. Data were collected using semi-structured interviews between October 2011 and March 2012. The sample consisted of 12 parents of minority ethnic backgrounds who had their child in a ward at a children's hospital in the Stockholm County Council. The interviews were analysed using manifest content analysis. The Regional Ethical Review Committee approved the study (Ref: Nr: 2011/927-31/5). The analysis of the interviews led to three categories: fundamentals in nursing, cultural sensitivity and understanding, and influencing conditions. Generic knowledge and skills of nurses outweighed the need for the nurses to have culture-specific knowledge of their patients or relatives in cross-cultural care encounters. Language skills and the availability of bilingual nurses in a multi-ethnic society can facilitate communication and increase parents' satisfaction in cross-cultural care encounters. © 2016 Nordic College of Caring Science.

Does the Hertz solution estimate pressures correctly in diamond indentor experiments?

Science.gov (United States)

Bruno, M. S.; Dunn, K. J.

1986-05-01

The Hertz solution has been widely used to estimate pressures in a spherical indentor against flat matrix type high pressure experiments. It is usually assumed that the pressure generated when compressing a sample between the indentor and substrate is the same as that generated when compressing an indentor against a flat surface with no sample present. A non-linear finite element analysis of this problem has shown that the situation is far more complex. The actual peak pressure in the sample is highly dependent on plastic deformation and the change in material properties due to hydrostatic pressure. An analysis with two material models is presented and compared with the Hertz solution.

The increase in research and application of various phototherapy methods, especially photodynamic therapy (PDT) has created the need to study in depth the mechanisms of interaction of light with biological tissue using a photosensitizing drug in order to increase the therapeutic effectiveness. In this issue, two systems for controlled irradiation of in-vitro cell culture and temperature monitoring of the culture are presented. The first system was designed to irradiate 24 wells in a 96-well microplate. The second one was constructed for the irradiation and control of a 24-well microplate using larger volumes of cultured cells. Both systems can independently irradiate and control the temperature of each well. The systems include a module for contactless measurement of the temperature in each well. Light sources are located in an interchangeable module, so that it can be replaced to irradiate with different wavelengths. These prototypes count with various operation modes, controlled by a computer, which permits establishing specific settings in accordance with the desired experiment. The systems allow the automated experiment execution with precise control of dosimetry, irradiation and temperature, which reduces the sample-handling while, saves time. (Author)

The University of Idaho (UI) was awarded a 5-year grant titled "Adaptation to change in water resources: science to inform decision-making across disciplines, cultures and scales", from the National Science Foundation's Integrative Graduate Education and Research Traineeship (IGERT) Program. The program supports over 20 doctoral students working in interdisciplinary teams, with participation across several departments and other universities including collaboration between the UI, Universidad Católica de la Santísima Concepción, and Universidad de Concepción in Chile. Each cohort of IGERT trainees visits Chile in their first year for a 2-week course focused on interdisciplinary water resource issues in the Bío Bío River Basin. Multiple field excursions are organized by faculty of the three institutions where students see first-hand the complexities, and the environmental and social consequences of rapid modernization. They then work in cross-cultural teams to identify research needs and potential solutions. One such project is entitled "Comparing USA and Chile hydropower system vulnerability to volcanic lahars". Comparisons are made between the geologic hazards, the associated hazard mitigation, and the emergency response plans at a Cascadian volcano and a pair of Andean volcanos. Geologic variables, dam specifications, government policies and regulations, scientific institutional capacity, and corporate influence are all considered in assessing the likelihood and consequences of a lahar interacting with, or causing failure of a dam. These consequences include loss of life, infrastructure destruction, degradation of water supply and quality, harm to sensitive plant and animals, and depressed local and regional economies. Given the locations of the case studies, special attention is paid to indigenous peoples and the cultural uses of the local environments. Recommendations accounting for both physical and social factors are made to strengthen deficiencies in

In this work, bioavailability and ecotoxicity of arsenite (As(III)) and arsenate (As(V)) species were compared between solution culture and soil system. Firstly, the adsorption of As(III) and As(V) was compared using a number of non-allophanic and allophanic soils. Secondly, the bioavailability and ecotoxicity were examined using germination, phytoavailability, earthworm, and soil microbial activity tests. Both As-spiked soils and As-contaminated sheep dip soils were used to test bioavailability and ecotoxicity. The sheep dip soil which contained predominantly As(V) species was subject to flooding to reduce As(V) to As(III) and then used along with the control treatment soil to compare the bioavailability between As species. Adsorption of As(V) was much higher than that of As(III), and the difference in adsorption between these two species was more pronounced in the allophanic than non-allophanic soils. In the solution culture, there was no significant difference in bioavailability and ecotoxicity, as measured by germination and phytoavailability tests, between these two As species. Whereas in the As-spiked soils, the bioavailability and ecotoxicity were higher for As(III) than As(V), and the difference was more pronounced in the allophanic than non-allophanic soils. Bioavailability of As increased with the flooding of the sheep dip soils which may be attributed to the reduction of As(V) to As(III) species. The results in this study have demonstrated that while in solution, the bioavailability and ecotoxicity do not vary between As(III) and As(V), in soils, the latter species is less bioavailable than the former species because As(V) is more strongly retained than As(III). Since the bioavailability and ecotoxicity of As depend on the nature of As species present in the environment, risk-based remediation approach should aim at controlling the dynamics of As transformation.

The lived experience of depression among culturally Deaf adults.

Science.gov (United States)

Sheppard, K; Badger, T

2010-11-01

Culturally Deaf adults lost hearing at early ages, communicate primarily in American Sign Language (ASL), and self-identify as culturally Deaf. Communication barriers lead to isolation, low self-esteem, abuse, and inadequate health care. Screening Deaf patients for depressive symptoms poses challenge. Nurses are rarely familiar with ASL, and depression screening tools aren't easily translated from English to ASL. Consequently, Deaf adults are not adequately screened for depression. Qualitative interviews were conducted with culturally Deaf adults, and certified interpreters helped to enhance understanding. Text was generated from interview transcriptions and researcher observations. No novel depressive symptoms were described. Various ASL signs were used to represent depression; two participants used a unique gesture that had no meaning to others. Childhood experiences leading to depression included sexual or physical abuse, feeling ostracized from family and like a burden. Suicidal gestures communicated severity of depression. Adults felt interpreters were unwelcome during mental health encounters. No participants were asked about depressive symptoms despite frank manifestations of depression. Study describes antecedents and consequences of depressive symptoms among Deaf adults. Understanding symptom manifestations and challenges experienced by Deaf patients helps identify those at risk for depression, thereby reducing morbidity and mortality. © 2010 Blackwell Publishing.

Laboratory experiments on solute transport in bimodal porous media under cyclic precipitation-evaporation boundary conditions

Science.gov (United States)

Cremer, Clemens; Neuweiler, Insa

2016-04-01

Flow and solute transport in the shallow subsurface is strongly governed by atmospheric boundary conditions. Erratically varying infiltration and evaporation cycles lead to alternating upward and downward flow, as well as spatially and temporally varying water contents and associated hydraulic conductivity of the prevailing materials. Thus presenting a highly complicated, dynamic system. Knowledge of subsurface solute transport processes is vital to assess e.g. the entry of, potentially hazardous, solutes to the groundwater and nutrient uptake by plant roots and can be gained in many ways. Besides field measurements and numerical simulations, physical laboratory experiments represent a way to establish process understanding and furthermore validate numerical schemes. With the aim to gain a better understanding and to quantify solute transport in the unsaturated shallow subsurface under natural precipitation conditions in heterogeneous media, we conduct physical laboratory experiments in a 22 cm x 8 cm x 1 cm flow cell that is filled with two types of sand and apply cyclic infiltration-evaporation phases at the soil surface. Pressure at the bottom of the domain is kept constant. Following recent studies (Lehmann and Or, 2009; Bechtold et al., 2011a), heterogeneity is introduced by a sharp vertical interface between coarse and fine sand. Fluorescent tracers are used to i) qualitatively visualize transport paths within the domain and ii) quantify solute leaching at the bottom of the domain. Temporal and spatial variations in water content during the experiment are derived from x-ray radiographic images. Monitored water contents between infiltration and evaporation considerably changed in the coarse sand while the fine sand remained saturated throughout the experiments. Lateral solute transport through the interface in both directions at different depths of the investigated soil columns were observed. This depended on the flow rate applied at the soil surface and

2017-01-01

Because of the development of novel micro-fabrication techniques to produce ultra-thin materials and increasing interest in thin biological membranes, in recent years, the mechanical characterization of thin films has received a significant amount of attention. To provide a more accurate solution for the relationship among contact radius, load and deflection, the fundamental and widely applicable problem of spherical indentation of a freestanding circular membrane have been revisited. The work presented here significantly extends the previous contributions by providing an exact analytical solution to the governing equations of Föppl–Hecky membrane indented by a frictionless spherical indenter. In this study, experiments of spherical indentation has been performed, and the exact analytical solution presented in this article is compared against experimental data from existing literature as well as our own experimental results.

Min, Hyewon; Park, Cheong Soo; Kim, Dong Soo

2014-01-01

Purpose Blood culture is the most important tool for detecting bacteremia in children with fever. However, blood culture contamination rates range from 0.6% to 6.0% in adults; rates for young children have been considered higher than these, although data are limited, especially in Korea. This study determined the contamination rate and risk factors in pediatric patients visiting the emergency room (ER) or being admitted to the ward. Methods We conducted a retrospective chart review of blood cultures obtained from children who visited Yonsei Severance Hospital, Korea between 2006 and 2010. Positive blood cultures were labeled as true bacteremia or contamination according to Centers for Disease Control and Prevention/National Healthcare Safety Network definitions for laboratory-confirmed bloodstream infection, after exclusion of cultures drawn from preexisting central lines only. Results Among 40,542 blood cultures, 610 were positive, of which 479 were contaminations and 131 were true bacteremia (overall contamination rate, 1.18%). The contamination rate in the ER was significantly higher than in the ward (1.32% vs. 0.66%, P6 years, respectively). Conclusion Overall, contamination rates were higher in younger children than in older children, given the difficulty of performing blood sampling in younger children. The contamination rates from the ER were higher than those from the ward, not accounted for only by overcrowding and lack of experience among personnel collecting samples. Further study to investigate other factors affecting contamination should be required. PMID:24868215

From an epistemological point of view that aligns with the phenomenological tradition with individual and group interviews, it was monitored with a longitudinal methodology as the representation of the transit cross-cultural adaptation to the context it emerged from the interviews are associated through the dominant narrative themes. The results show how in the early stage of contact with the new culture, the group of students, both European and not, have felt a sense of disorientation associated with the loss of its cultural matrix. Over the next step of analysis is rather more clearly the difference between the group of European students, whose performances evoke an adjustment process easier and less based on feelings of ambivalence and close relationships that characterize the group of non-European students.Keywords: Cross-cultural transition; International students: Phenomenology

This study discovers, describes, and explains the personal experiences, perceptions, and care meanings of Jordanian women who have suffered postpartum depression. Most postpartum cases often are misdiagnosed as exclusively psychological and untreated by health care professionals without consideration to the cultural meanings of this problem. Understanding the experiences of these women is important, as their expressions often are contextually and culturally influenced. Using Leininger's Theory of Culture Care Diversity and Universality, a purposive sample of 22 Jordanian women diagnosed with postpartum depression, living in Sydney, were interviewed. The ethnonursing research method and data analysis procedures were used. Results revealed that Jordanian mothers experienced severe loss of control over emotions of loneliness, hopelessness, and feelings of being a bad mother. Three major themes focusing on the care meanings and experiences of Jordanian women are discussed: (a) Care means strong family support and kinship during the postpartum period, (b) care is carrying out and fulfilling traditional gender roles as mother and wife, and (c) care is preservation of Jordanian childbearing customs as expressed in the celebration of the birth of the baby.

The prototype of a miniaturized cell cultivation instrument for animal cell culture experiments aboard Spacelab is presented (Dynamic cell culture system: DCCS). The cell chamber is completely filled and has a working volume of 200 microliters. Medium exchange is achieved with a self-powered osmotic pump (flowrate 1 microliter h-1). The reservoir volume of culture medium is 230 microliters. The system is neither mechanically stirred nor equipped with sensors. Hamster kidney (Hak) cells growing on Cytodex 3 microcarriers were used to test the biological performance of the DCCS. Growth characteristics in the DCCS, as judged by maximal cell density, glucose consumption, lactic acid secretion and pH, were similar to those in cell culture tubes.

Full Text Available What does it mean to learn in a group of people from different cultures? How does one encounter people from different cultures when there is no clear ‘quantitative’ domination of any culture? By asking these questions the paper represents a hermeneutic phenomenological study that explores the phenomenon of learning in a culturally diverse group. A phenomenological study is undertaken with young people (18-30 years from different EU countries who participated in learning mobility project European Voluntary Service and had long-term volunteering experience abroad. The research concentrates on the lived moments of vis-à-vis intercultural encounters during learning process in groups. Specifically, through the descriptions of lived experience and phenomenological reflection the paper describes how young people experience self and others while they are learning in culturally diverse groups. Lived experiences of young people lead them into ‘no-man’s land’ (Waldenfels, 2011 where connection and separation simultaneously exist.

Column experiments, simulating the behavior of passive treatment systems for acid mine drainage, have been performed. Acid solutions (HCl or H{sub 2}SO{sub 4}, pH 2), with initial concentrations of Fe(III) ranging from 250 to 1500 mg L{sup -1}, were injected into column reactors packed with calcite grains at a constant flow rate. The composition of the solutions was monitored during the experiments. At the end of the experiments (passivation of the columns), the composition and structure of the solids were measured. The dissolution of calcite in the columns caused an increase in pH and the release of Ca into the solution, leading to the precipitation of gypsum and Fe-oxyhydroxysulfates (Fe(III)-SO{sub 4}-H{sup +} solutions) or Fe-oxyhydroxychlorides (Fe(III)-Cl-H{sup +} solutions). The columns worked as an efficient barrier for some time, increasing the pH of the circulating solutions from 2 to {approx}6-7 and removing its metal content. However, after some time (several weeks, depending on the conditions), the columns became chemically inert. The results showed that passivation time increased with decreasing anion and metal content of the solutions. Gypsum was the phase responsible for the passivation of calcite in the experiments with Fe(III)-SO{sub 4}-H{sup +} solutions. Schwertmannite and goethite appeared as the Fe(III) secondary phases in those experiments. Akaganeite was the phase responsible for the passivation of the system in the experiments with Fe(III)-Cl-H{sup +} solutions.

Full Text Available Katie Owens,1 Jim Eggers,2 Stephanie Keller,1 Audrey McDonald1 1HealthStream Engagement Institute, Pensacola, FL, 2Analytics, HealthStream, Laurel, MD, USA Abstract: Current uncertainty for the future of the health care landscape is placing an increasing amount of pressure on leadership teams to be prepared to steer their organization forward in a number of potential directions. It is commonly recognized among health care leaders that culture will either enable or disable organizational success. However, very few studies empirically link culture to health care-specific performance outcomes. Nearly every health care organization in the US specifies its cultural aspirations through mission and vision statements and values. Ambitions of patient-centeredness, care for the community, workplace of choice, and world-class quality are frequently cited; yet, little definitive research exists to quantify the importance of building high-performing cultures. Our study examined the impact of cultural attributes defined by a culture index (Cronbach’s alpha = 0.88 on corresponding performance with key health care measures. We mapped results of the culture index across data sets, compared results, and evaluated variations in performance among key indicators for leaders. Organizations that perform in the top quartile for our culture index statistically significantly outperformed those in the bottom quartile on all but one key performance indicator tested. The culture top quartile organizations outperformed every domain for employee engagement, physician engagement, patient experience, and overall value-based purchasing performance with statistical significance. Culture index top quartile performers also had a 3.4% lower turnover rate than the bottom quartile performers. Finally, culture index top quartile performers earned an additional 1% on value-based purchasing. Our findings demonstrate a meaningful connection between performance in the culture index and

The place of experience, culture and multimedia learning in teacher training

Full Text Available What are the challenges of training children, young people and teachers today? Speaking of knowledge and skills necessary for teachers to perform in current scenarios implies asking to what extent university degree courses and teacher training institutions are adapting to the new demands of education. By highlighting some current challenges of university education, this article emphasizes the importance of experience, cultural training and multimedia in teacher training, from a culturalistic perspective of media education. Considering that media education is a field under construction, the transversality and the contribution of multidisciplinary knowledge of science, education, communication and the arts are a “border-object”, an interface that can better interpret the current transformation of knowledge and the tools of digital culture which are not limited to school education. The text discusses the possibility of multimedia education and its skills, such as integration of knowledge and methodological contributions deriving from different areas of knowledge and from the perspective of multiple languages in school and culture. From this results the need to set up other spaces for thinking about educational and training praxis, discussing news forms of cultural mediation in contemporary settings of teachers training.

This study relates parenting of 3-month-old children to children's self-recognition and self-regulation at 18 to 20 months. As hypothesized, observational data revealed differences in the sociocultural orientations of the 3 cultural samples' parenting styles and in toddlers' development of self-recognition and self-regulation. Children of Cameroonian Nso farmers who experience a proximal parenting style develop self-regulation earlier, children of Greek urban middle-class families who experience a distal parenting style develop self-recognition earlier, and children of Costa Rican middle-class families who experience aspects of both distal and proximal parenting styles fall between the other 2 groups on both self-regulation and self-recognition. Results are discussed with respect to their implications for culturally informed developmental pathways.

Sandra Fatorić

2017-11-01

Full Text Available Climate change challenges cultural heritage management and preservation. Understanding the barriers that can impede preservation is of paramount importance, as is developing solutions that facilitate the planning and management of vulnerable cultural resources. Using online survey research, we elicited the opinions of diverse experts across southeastern United States, a region with cultural resources that are particularly vulnerable to flooding and erosion from storms and sea level rise. We asked experts to identify the greatest challenges facing cultural heritage policy and practice from coastal climate change threats, and to identify strategies and information needs to overcome those challenges. Using content analysis, we identified institutional, technical and financial barriers and needs. Findings revealed that the most salient barriers included the lack of processes and preservation guidelines for planning and implementing climate adaptation actions, as well as inadequate funding and limited knowledge about the intersection of climate change and cultural heritage. Experts perceived that principal needs to overcome identified barriers included increased research on climate adaptation strategies and impacts to cultural heritage characteristics from adaptation, as well as collaboration among diverse multi-level actors. This study can be used to set cultural heritage policy and research agendas at local, state, regional and national scales.

Experience with control valve cavitation problems and their solutions

International Nuclear Information System (INIS)

Ozol, J.

1988-01-01

Pressure reduction in control valves can induce cavitation, which has three effects on the control valve. Firstly, it modifies or changes the hydraulic performance of the control valve. Since control valves are designed for noncavitating conditions, the result is usually reduced stability of the control valve or, in extreme cavitating conditions known as supercavitation, the valve may limit the flow rate and thus be undersized. Secondly, cavitation can cause material damage to valve parts, trim, or valve body, or erodes downstream piping; consequently, the valve or piping leaks. Thirdly, cavitation causes noise and vibration, which may cause major damage or destruction to equipment such as valve positioners, actuators, pipe supports and sometimes to other downstream valves. The purpose of this paper is twofold: (1) It describes the I.S.A. valve sizing equations and how they relate to cavitation. (2) It describes experiences with these three problems, and discusses corrective actions and practical approaches to their solution. This paper discusses thirteen cavitation experiences

Within the nuclear industry there are two events which have had a significant impact on the way of thinking and attitudes to safety, although in different ways. The TMI accident at Harrisburg, USA put the focus on Man-Machine interface, the way of working and attitudes to safety. The accident at Chernobyl focused on Safety Management and Safety Culture. Before the TMI accident, technology was believed to be the solutions to all kinds of problems. Technical solutions should compensate for human behaviour. After the TMI accident the focus was put on Man-Machine issues and a lot of the resources within the Nuclear Industry was allocated to Man-Machine-Interfaces, Procedures, Training, etc. After the Chernobyl accident, safety culture (IAEA INSAG-4) became a commonly used concept which included an overall perspective on safety and an understanding of the interaction between Man, Technology and Organizational matters (MTO). The Safety Culture within an organization is the sum of all attitudes, qualities and experiences influencing safety. Safety Culture is consequently not only a single quality or a single property but a generic term representing the promotion of safety in many areas.

Critical experiments have been conducted with organically moderated mixed-oxide (MOX) fuel pin assemblies at the Pacific Northwest Lab. Critical Mass Lab. These experiments are part of a joint exchange program between the US Dept. of Energy and the Power Reactor and Nuclear Fuel Development Corp. of Japan in the area of criticality data development. The purpose of these experiments is to benchmark computer codes and cross-section libraries and to assess the reactivity difference between systems moderated by water and those moderated by an organic solution. Past studies have indicated that some organic mixtures may be better moderators than water. This topic is of particular importance to the criticality safety of fuel processing plants where fissile material is dissolved in organic solutions during the solvent extraction process. In the past, it has been assumed that the codes and libraries benchmarked with water-moderated experiments were adequate when performing design and licensing studies of organically moderated systems. Calculations presented in this paper indicated that the Scale code system and the 27-energy-group cross-section library accurately compute k/sub eff/ for organically moderated MOX fuel pin assemblies. Furthermore, the reactivity of an organic solution with a 32 vol % TBP/68 vol% NPH mixture in a heterogeneous configuration is the same, for practical purposes, as water

Fine suspended particles are typically considered to pass through streams and rivers as wash load without interacting with the bed, however experiments have demonstrated that hyporheic flow causes advective exchange of fine particles with the stream bed, yielding accumulation of fine particle deposits within the bed. Ultimately, understanding river morphodynamics and ecosystem dynamics requires coupling both fine particle and solute transport with bed morphodynamics. To better understand the coupling between these processes we analyze a novel dataset from a controlled field experiment conducted on Clear Run, a 2nd order sand bed stream located within the North Carolina coastal plain. Data include concentrations of continuously injected conservative solutes and fine particulate tracers measured at various depths within the stream bed, overhead time lapse images of bed forms, stream discharge, and geomorphological surveys of the stream. We use image analysis of bed morphodynamics to assess exchange, retention, and remobilization of solutes and fine particles during constant discharge and a short duration experimental flood. From the images, we extract a time series of bedform elevations and scour depths for the duration of the experiment. The high-resolution timeseries of bed elevation enables us to assess coupling of bed morphodynamics with both the solute and fine particle flux during steady state mobile bedforms prior to the flood and to changing bedforms during the flood. These data allow the application of a stochastic modeling framework relating bed elevation fluctuations to fine particle residence times. This combined experimental and modeling approach ultimately informs our ability to predict not only the fate of fine particulate matter but also associated nutrient and carbon dynamics within streams and rivers.

Full Text Available In the current sociocultural and commercial context, transnational companies base their communication policies on a phenomenon of expansive branding of their own brand names, converted into products of symbolic consumption. In the face of these policies, founded on the use of cultural and countercultural elements as circulation strategies, a whole series of cultural resistance movements attempt to counteract the actions of the large multinationals with strategies similar to those that these companies employ. In this article, the author analyses this game of attack-counterattack, calling attention to the “reversible” nature of such actions, founded on the commercial exploitation of the expressive experiences of their social targets.

The open raceway ponds are nowadays the most used large-scale reactors for microalgae culture. To avoid the stacking of microalgae, the paddle wheels are the most widely used to circulate and mix the culture medium. In this paper, a numerical simulation using computational fluid dynamics (CFD) was used to investigate the hydrodynamic characteristics of open raceway ponds with different types of paddle wheels (the traditional paddle wheels and the novel paddle wheels with specially inclined angle of the blades). The particle image velocimetry (PIV) was used to validate the reliability of the CFD model. The CFD simulation results showed that the novel raceway pond with 15° inclined angle of the blades had the best mixing efficiency under the same power consumption. Lastly, the results of microalgae culture experiments showed that the growth rates of Chlorella pyrenoidosa in the novel raceway pond with 15° inclined angle of the blades were higher than those in the traditional reactor. The results of the culture experiments and CFD simulations were identical with each other. Therefore, a novel paddle wheel with 15° inclined angle of the blades was obtained for better microalgae cultivation.

Critical experiments on an enriched uranium solution system containing periodically distributed strong thermal neutron absorbers

Rothe, R.E.

1996-01-01

A series of 62 critical and critical approach experiments were performed to evaluate a possible novel means of storing large volumes of fissile solution in a critically safe configuration. This study is intended to increase safety and economy through use of such a system in commercial plants which handle fissionable materials in liquid form. The fissile solution's concentration may equal or slightly exceed the minimum-critical-volume concentration; and experiments were performed for high-enriched uranium solution. Results should be generally applicable in a wide variety of plant situations. The method is called the 'Poisoned Tube Tank' because strong neutron absorbers (neutron poisons) are placed inside periodically spaced stainless steel tubes which separate absorber material from solution, keeping the former free of contamination. Eight absorbers are investigated. Both square and triangular pitched lattice patterns are studied. Ancillary topics which closely model typical plant situations are also reported. They include the effect of removing small bundles of absorbers as might occur during inspections in a production plant. Not taking the tank out of service for these inspections would be an economic advantage. Another ancillary topic studies the effect of the presence of a significant volume of unpoisoned solution close to the Poisoned Tube Tank on the critical height. A summary of the experimental findings is that boron compounds were excellent absorbers, as expected. This was true for granular materials such as Gerstley Borate and Borax; but it was also true for the flexible solid composed of boron carbide and rubber, even though only thin sheets were used. Experiments with small bundles of absorbers intentionally removed reveal that quite reasonable tanks could be constructed that would allow a few tubes at a time to be removed from the tank for inspection without removing the tank from production service

Combining universal beauty and cultural context in a unifying model of visual aesthetic experience.

Science.gov (United States)

Redies, Christoph

2015-01-01

In this work, I propose a model of visual aesthetic experience that combines formalist and contextual aspects of aesthetics. The model distinguishes between two modes of processing. First, perceptual processing is based on the intrinsic form of an artwork, which may or may not be beautiful. If it is beautiful, a beauty-responsive mechanism is activated in the brain. This bottom-up mechanism is universal amongst humans; it is widespread in the visual brain and responsive across visual modalities. Second, cognitive processing is based on contextual information, such as the depicted content, the intentions of the artist or the circumstances of the presentation of the artwork. Cognitive processing is partially top-down and varies between individuals according to their cultural experience. Processing in the two channels is parallel and largely independent. In the general case, an aesthetic experience is induced if processing in both channels is favorable, i.e., if there is resonance in the perceptual processing channel ("aesthetics of perception"), and successful mastering in the cognitive processing channel ("aesthetics of cognition"). I speculate that this combinatorial mechanism has evolved to mediate social bonding between members of a (cultural) group of people. Primary emotions can be elicited via both channels and modulate the degree of the aesthetic experience. Two special cases are discussed. First, in a subset of (post-)modern art, beauty no longer plays a prominent role. Second, in some forms of abstract art, beautiful form can be enjoyed with minimal cognitive processing. The model is applied to examples of Western art. Finally, implications of the model are discussed. In summary, the proposed model resolves the seeming contradiction between formalist perceptual approaches to aesthetic experience, which are based on the intrinsic beauty of artworks, and contextual approaches, which account for highly individual and culturally dependent aspects of aesthetics.

Inclusive cultural empathy for successful global leadership.

Science.gov (United States)

Pedersen, Paul B; Pope, Mark

2010-11-01

Empathy is reported in the research literature as a necessary factor in counseling and psychotherapy, but psychologists have historically interpreted empathy through an exclusively individual focus. Most of the research on empathy has been predicated on a definition of empathy as occurring when one person vicariously experiences the feelings, perceptions, and thoughts of another. In Western cultures, the study of empathy focuses exclusively on the individual, whereas in traditional non-Western cultures, empathy more typically involves an inclusive perspective focusing on the individual and significant others in the societal context. This article explores the reframing of "empathy," based on an individualistic perspective, into "inclusive cultural empathy," based on a more relationship-centered perspective, as an alternative interpretation of the empathic process. Psychologists are both the problem and the solution to this dilemma, and the authors call upon the field to take leadership in applying this "inclusive cultural empathy" model.

Highlights: • The viscosities of the carbonated AMP-PZ aqueous solutions were measured. • The experiments were modeled satisfactorily by using the Weiland equation. • The influence of the mass fractions of amines on the viscosity was illustrated. • The temperature and CO 2 loading dependences of the viscosity were demonstrated. -- Abstract: The viscosities (η) of carbonated 2-amino-2-methyl-1-propanol (AMP)-piperazine (PZ) aqueous solutions were measured by using a NDJ-1 rotational viscometer, with temperatures ranging from 298.15 K to 323.15 K. The total mass fraction of amines ranged from 0.3 to 0.4. The mass fraction of PZ ranged from 0.05 to 0.10. The Weiland equation was used to correlate the viscosities of both CO 2 -unloaded and CO 2 -loaded aqueous solutions and the calculated results agreed well with the experiments. The effects of temperature, mass fractions of amines and CO 2 loading (α) on the viscosities of carbonated aqueous solutions were demonstrated on the basis of experiments and calculations

Cleveland, Lisa M; Horner, Sharon D

2012-04-01

To explore the experiences of Mexican-American mothers who have had infants in the neonatal intensive care unit (NICU). A convenience sample of 15 English-speaking, Mexican-American women was interviewed. The study used an exploratory qualitative approach. Data collection was conducted through audiotaped, transcribed, semistructured, individual interviews and field notes. The 5 normative cultural values for Latino families-(1) simpatia, (2) personalismo, (3) respeto, (4) familismo, and (5) fatalismo-were used as a sensitizing framework to guide data interpretation. The women's discussions of their NICU experiences clearly reflect the 5 normative Latino cultural values. Positive and negative exemplars of these values are provided as evidence. These findings can be used to inform nursing care provided for Mexican-American mothers and their infants by assisting nurses to customize care to meet the cultural needs of this population.

Dominant Cultural Narratives, Racism, and Resistance in the Workplace: A Study of the Experiences of Young Black Canadians.

Science.gov (United States)

Hasford, Julian

2016-03-01

Although many studies have examined lived experiences of racism and resistance in various contexts, relatively little research has examined such experiences among Black youth within the workplace-particularly in the Canadian context. In this study I use qualitative analyses of narrative interviews with 24 Black Canadian youth and young adults (aged 16-35) to examine the impact of dominant cultural narratives on lived experiences of workplace racism and resistance. Findings are presented using theatrical games as a central conceptual metaphor, suggesting that: (a) dominant cultural narratives have a major impact on relational dynamics of oppression in the workplace; (b) identity performance is a critical strategy for negotiating dominant cultural narratives in the workplace; and (c) panopticism (the internalized gaze) is a significant aspect of internalized oppression. Implications for future research and action are discussed. © Society for Community Research and Action 2016.

Rare earth element Dy is one of the promising alloying elements for magnesium alloy as biodegradable implants. To understand the effect of Dy in solid solution on the degradation of Mg-Dy alloys in simulated physiological conditions, the present work studied the microstructure and degradation behavior of Mg-Dy alloys in cell culture medium. It is found the corrosion resistance enhances with the increase of Dy content in solid solution in Mg. This can be attributed to the formation of a relatively more corrosion resistant Dy-enriched film which decreases the anodic dissolution of Mg. Copyright © 2017 Elsevier B.V. All rights reserved.

Githaiga, Jennifer Nyawira

2017-10-01

This article explores the experiences of a small group of Nairobi women caring for a family cancer patient at home. On the basis of literature on women as caregivers in Africa, and on other literature more broadly, it was anticipated that issues around generational roles, gender and women's cultural role would be relevant. Seven women participated in semi-structured in-depth interviews, while thirteen women participated in four mini focus groups. Data were analysed using interpretative phenomenological analysis. Findings underscore the socio-cultural complexities of caregiving as a basis for evidence-based culturally appropriate structures to support family caregivers.

In this report, we describe the results of a rat pituitary cell culture experiment done on STS-65 in which the effect of cell feeding on the release of the six anterior pituitary hormones was studied. We found complex microgravity related interactions between the frequency of cell feeding and the quantity and quality (i.e. biological activity) of some of the six hormones released in flight. Analyses of growth hormone (GH) released from cells into culture media on different mission days using gel filtration and ion exchange chromatography yielded qualitatively similar results between ground and flight samples. Lack of cell feeding resulted in extensive cell clumping in flight (but not ground) cultures. Vigorous fibroblast growth occurred in both ground and flight cultures fed 4 times. These results are interpreted within the context of autocrine and or paracrine feedback interactions. Finally the payload specialist successfully prepared a fresh trypsin solution in microgravity, detached the cells from their surface and reinserted them back into the culture chamber. These cells reattached and continued to release hormone in microgravity. In summary, this experiment shows that pituitary cells are microgravity sensitive and that coupled operations routinely associated with laboratory cel1 culture can also be accomplished in low gravity.

Context Influences on the Subjective Experience of Aging: The Impact of Culture and Domains of Functioning.

Attitudes about aging influence how people feel about their aging and affect psychological and health outcomes in later life. Given cross-cultural variability in such attitudes, the subjective experience of aging (e.g., subjective age [SA]) may also vary, potentially accounting for culture-specific patterns of aging-related outcomes. Our study explored cultural variation in SA and its determinants. American (N = 569), Chinese (N = 492), and German (N = 827) adults aged 30-95 years completed a questionnaire that included instruments measuring basic demographic information, SA, beliefs about thresholds of old age, control over life changes, and age dependency of changes in eight different life domains (i.e., family, work). Analyses revealed consistency across cultures in the domain-specificity of SA, but differences in the amount of shared variance across domains (e.g., Chinese adults exhibited greater homogeneity across domains than did Americans and Germans). Cultural differences were also observed in levels of SA in some domains, which were attenuated by domain-specific beliefs (e.g., control). Interestingly, beliefs about aging accounted for more cultural variation in SA than did sociodemographic factors (e.g., education). Our results demonstrate that subjective perceptions of aging and everyday functioning may be best understood from a perspective focused on context (i.e., culture, life domain). Given its important relation to functioning, examination of cross-cultural differences in the subjective experience of aging may highlight factors that determine variations in aging-related outcomes that then could serve as targets of culture-specific interventions promoting well-being in later life. © The Author 2017.

Due to the rising interest in Europe to treat large cartilage defects with osteochondrale allografts, research aims to find a suitable solution for long-term storage of osteochondral allografts. This is further encouraged by the fact that legal restrictions currently limit the use of the ingredients from animal or human sources that are being used in other regions of the world (e.g. in the USA). Therefore, the aim of this study was A) to analyze if a Lactated Ringer (LR) based solution is as efficient as a Dulbecco modified Eagle's minimal essential medium (DMEM) in maintaining chondrocyte viability and B) at which storage temperature (4°C vs. 37°C) chondrocyte survival of the osteochondral allograft is optimally sustained. 300 cartilage grafts were collected from knees of ten one year-old Black Head German Sheep. The grafts were stored in four different storage solutions (one of them DMEM-based, the other three based on Lactated Ringer Solution), at two different temperatures (4 and 37°C) for 14 and 56days. At both points in time, chondrocyte survival as well as death rate, Glycosaminoglycan (GAG) content, and Hydroxyproline (HP) concentration were measured and compared between the grafts stored in the different solutions and at the different temperatures. Independent of the storage solutions tested, chondrocyte survival rates were higher when stored at 4°C compared to storage at 37°C both after short-term (14days) and long-term storage (56days). At no point in time did the DMEM-based solution show a superior chondrocyte survival compared to lactated Ringer based solution. GAG and HP content were comparable across all time points, temperatures and solutions. LR based solutions that contain only substances that are approved in Germany may be just as efficient for storing grafts as the USA DMEM-based solution gold standard. Moreover, in the present experiment storage of osteochondral allografts at 4°C was superior to storage at 37°C. Copyright © 2017

The goal of the University of Hawaii (UH) child and adolescent psychiatry telemental health (TMH) program is to train child and adolescent psychiatry fellows to provide behavioral health services for the children of Hawaii and the Pacific Islands in the cultural context of their rural communities using interactive videoteleconferencing (IVTC). The training experience balances learning objectives with community service. Learning objectives include: Understanding mental health disparities in rural communities, leveraging community resources in ongoing treatment, providing culturally effective care, and improving health care access and delivery through TMH service research and evaluation. We describe the UH experience. Several UH faculty are experienced with IVTC technology. They are triple-board trained, are recognized for their research in program evaluation and mental health disparities, and are committed to serving Hawaii's rural communities. We demonstrate the role of TMH in linking children and their families living in rural communities with multiple mental health treatment providers. The service-learning curriculum and a unique collaboration with Mayo Clinic provide the opportunity to examine the role of TMH in global service, and training, education, and research. TMH provides direct services to patients and consultation on Hawaii Island and Maui County. The collaboration with the Mayo Clinic brings further consultation in complex diagnostics, pharmacogenomics, and cross-cultural psychiatry. A curriculum provides trainees experience with IVTC with the goal of potential recruitment to underserved rural communities. The TMH program at UH is unique in its team building and workforce development by joining multiple entities through IVTC and translating expertise from the Mayo Clinic to rural communities, and strengthening collaboration with local child and adolescent psychiatrists, and primary care and other mental health providers. The UH psychiatry program is a

Reversible gelling culture media for in-vitro cell culture in three-dimensional matrices

An, Yuehuei H.; Mironov, Vladimir A.; Gutowska, Anna

2000-01-01

A gelling cell culture medium useful for forming a three dimensional matrix for cell culture in vitro is prepared by copolymerizing an acrylamide derivative with a hydrophilic comonomer to form a reversible (preferably thermally reversible) gelling linear random copolymer in the form of a plurality of linear chains having a plurality of molecular weights greater than or equal to a minimum gelling molecular weight cutoff, mixing the copolymer with an aqueous solvent to form a reversible gelling solution and adding a cell culture medium to the gelling solution to form the gelling cell culture medium. Cells such as chondrocytes or hepatocytes are added to the culture medium to form a seeded culture medium, and temperature of the medium is raised to gel the seeded culture medium and form a three dimensional matrix containing the cells. After propagating the cells in the matrix, the cells may be recovered by lowering the temperature to dissolve the matrix and centrifuging.

This paper presents a novel approach to content delivery for video streaming services. It exploits information from connected eye-trackers embedded in the next generation of VR Head Mounted Displays (HMDs). The proposed solution aims to deliver high visual quality, in real time, around the users' fixations points while lowering the quality everywhere else. The goal of the proposed approach is to substantially reduce the overall bandwidth requirements for supporting VR video experiences while delivering high levels of user perceived quality. The prerequisites to achieve these results are: (1) mechanisms that can cope with different degrees of latency in the system and (2) solutions that support fast adaptation of video quality in different parts of a frame, without requiring a large increase in bitrate. A novel codec configuration, capable of supporting near-instantaneous video quality adaptation in specific portions of a video frame, is presented. The proposed method exploits in-built properties of HEVC encoders and while it introduces a moderate amount of error, these errors are indetectable by users. Fast adaptation is the key to enable gaze-aware streaming and its reduction in bandwidth. A testbed implementing gaze-aware streaming, together with a prototype HMD with in-built eye tracker, is presented and was used for testing with real users. The studies quantified the bandwidth savings achievable by the proposed approach and characterize the relationships between Quality of Experience (QoE) and network latency. The results showed that up to 83% less bandwidth is required to deliver high QoE levels to the users, as compared to conventional solutions.

The primary aim of in vitro culture of whipworms (Trichuris ovis) is to provide artificial conditions under which the life cycle of the parasites completed outside the host under controlled conditions. The physiological solutions used for the present study were sodium chloride (0.64%), Ringer's solution, Tyrode's solution, and Lock-Lewis solution. Parasites were collected from freshly slaughtered intestine of the host. The recovered parasites were washed with running tap water after that with normal saline. After washing parasites were put in four petridishes containing different physiological solutions. Observations were recorded after interval of every 8 h. The hundred percent survival of Trichuris ovis was observed at 32, 40, and 48 h in NaCl (0.64%), Ringer's, Tyrode's, and Lock-Lewis solution, respectively in case of both male and female parasites. In sodium chloride solution (0.64%) cent percent mortality was observed after 64 h of incubation in males and in case of females it was observed 72 h. In Ringer's solution cent percent mortality was observed after 72 in males and in females it was observed 80 h. In Tyrode's solution cent percent mortality was observed after 88 h in males and 96 h in females. In Lock-Lewis solution cent percent mortality was observed after 96 h in case of both the male and female parasites. Present study could be used to understand the effects of various drugs on the above parasites and also other intra-intestinal parasites.

A healthy workplace culture enables nurses to experience valuable learning in the workplace. Learning in the workplace enables the provision of evidence-based and continuously improving safe patient care, which is central to achieving good patient outcomes. Therefore, nurses need to learn within a workplace that supports the implementation of evidence-based, professional practice and enables the best patient outcomes; the influence of workplace culture may play a role in this. The purpose of this review was to critically appraise and synthesize the best available qualitative evidence to understand both the nurses' learning experiences within the workplace and the factors within the workplace culture that influence those learning experiences. Registered and enrolled nurses regulated by a nursing and midwifery board and/or recognized health practitioner regulation agency (or their international equivalent). This review considered studies that described two phenomena of interest: the nurses' learning experience, either within an acute healthcare workplace or a workplace-related learning environment and the influence of workplace culture on the nurses' learning experience (within the workplace or workplace-related learning environment). This review considered studies that included nurses working in an acute healthcare organization within a Western culture. This review considered studies that focused on qualitative evidence and included the following research designs: phenomenological, grounded theory and critical theory. Published and unpublished studies in English from 1980 to 2013 were identified using a three-step search strategy, searching various databases, and included hand searching of the reference lists within articles selected for appraisal. For studies meeting the inclusion criteria, methodological quality was assessed using a standardized checklist from the Joanna Briggs Institute Qualitative Assessment and Review Instrument (JBI-QARI).

Flocking multiple microparticles with automatically controlled optical tweezers: solutions and experiments.

Science.gov (United States)

Chen, Haoyao; Wang, Can; Lou, Yunjiang

2013-06-01

This paper presents an efficient approach to achieve microparticles flocking with robotics and optical tweezers technologies. All particles trapped by optical tweezers can be automatically moved toward a predefined region without collision. The main contribution of this paper lies in the proposal of several solutions to the flocking manipulation of microparticles in microenvironments. First, a simple flocking controller is proposed to generate the desired positions and velocities for particles' movement. Second, a velocity saturation method is implemented to prevent the desired velocities from exceeding a safe limit. Third, a two-layer control architecture is proposed for the motion control of optical tweezers. This architecture can help make many robotic manipulations achievable under microenvironments. The proposed approach with these solutions can be applied to many bioapplications especially in cell engineering and biomedicine. Experiments on yeast cells with a robot-tweezers system are finally performed to verify the effectiveness of the proposed approach.

Multiweek cell culture project for use in upper-level biology laboratories.

Marion, Rebecca E; Gardner, Grant E; Parks, Lisa D

2012-06-01

This article describes a laboratory protocol for a multiweek project piloted in a new upper-level biology laboratory (BIO 426) using cell culture techniques. Human embryonic kidney-293 cells were used, and several culture media and supplements were identified for students to design their own experiments. Treatments included amino acids, EGF, caffeine, epinephrine, heavy metals, and FBS. Students researched primary literature to determine their experimental variables, made their own solutions, and treated their cells over a period of 2 wk. Before this, a sterile technique laboratory was developed to teach students how to work with the cells and minimize contamination. Students designed their experiments, mixed their solutions, seeded their cells, and treated them with their control and experimental media. Students had the choice of manipulating a number of variables, including incubation times, exposure to treatment media, and temperature. At the end of the experiment, students observed the effects of their treatment, harvested and dyed their cells, counted relative cell numbers in control and treatment flasks, and determined the ratio of living to dead cells using a hemocytometer. At the conclusion of the experiment, students presented their findings in a poster presentation. This laboratory can be expanded or adapted to include additional cell lines and treatments. The ability to design and implement their own experiments has been shown to increase student engagement in the biology-related laboratory activities as well as develop the critical thinking skills needed for independent research.

Despite growing evidence of the benefits of including assessment for learning strategies within programmes of assessment, practical implementation of these approaches is often problematical. Organisational culture change is often hindered by personal and collective beliefs which encourage adherence to the existing organisational paradigm. We aimed to explore how these beliefs influenced proposals to redesign a summative assessment culture in order to improve students' use of assessment-related feedback. Using the principles of participatory design, a mixed group comprising medical students, clinical teachers and senior faculty members was challenged to develop radical solutions to improve the use of post-assessment feedback. Follow-up interviews were conducted with individual members of the group to explore their personal beliefs about the proposed redesign. Data were analysed using a socio-cultural lens. Proposed changes were dominated by a shared belief in the primacy of the summative assessment paradigm, which prevented radical redesign solutions from being accepted by group members. Participants' prior assessment experiences strongly influenced proposals for change. As participants had largely only experienced a summative assessment culture, they found it difficult to conceptualise radical change in the assessment culture. Although all group members participated, students were less successful at persuading the group to adopt their ideas. Faculty members and clinical teachers often used indirect techniques to close down discussions. The strength of individual beliefs became more apparent in the follow-up interviews. Naïve epistemologies and prior personal experiences were influential in the assessment redesign but were usually not expressed explicitly in a group setting, perhaps because of cultural conventions of politeness. In order to successfully implement a change in assessment culture, firmly-held intuitive beliefs about summative assessment will need to

Men, culture and hegemonic masculinity: understanding the experience of prostate cancer.

Science.gov (United States)

Wall, David; Kristjanson, Linda

2005-06-01

Following a diagnosis of, and treatment for prostate cancer, there is an expectation that men will cope with, adjust to and accept the psychosocial impact on their lives and relationships. Yet, there is a limited qualitative world literature investigating the psychosocial experience of prostate cancer, and almost no literature exploring how masculinity mediates in such an experience. This paper will suggest that the experience of prostate cancer, the process by which it is investigated, and the way in which it is understood has been shaped by an essentialist interpretation of gender, exemplified by hegemonic masculinity as the archetypal mechanism of male adaptation. In response to this static and limiting view of masculinity, this paper will offer a reframe of hegemonic masculinity. This reframe, being more aligned with common experience, will portray masculinity as a dynamic and contextual construct, better understood as one of a number of cultural reference points around which each man organises and adopts behaviour. It will be suggested that the extant literature, in being organised around hegemonic masculinity, obfuscates the experience of prostate cancer and acts to render covert any collateral masculinities, public or private, that may also be operating.

Culture and gender shape emotion experience and regulation, in part because the value placed on emotions and the manner of their expression is thought to vary across these groups. This study tested the hypothesis that culture and gender would interact to predict people's emotion responding (emotion intensity and regulatory strategies). Chinese (n=220; 52% female) and American undergraduates (n=241; 62% female) viewed photos intended to elicit negative emotions after receiving instructions to either "just feel" any emotions that arose (Just Feel), or to "do something" so that they would not experience any emotion while viewing the photos (Regulate). All participants then rated the intensity of their experienced emotions and described any emotion-regulation strategies that they used while viewing the photos. Consistent with predictions, culture and gender interacted with experimental condition to predict intensity: Chinese men reported relatively low levels of emotion, whereas American women reported relatively high levels of emotion. Disengagement strategies (especially distancing) were related to lower emotional intensity and were reported most often by Chinese men. Taken together, findings suggest that emotion-regulation strategies may contribute to differences in emotional experience across Western and East Asian cultures.

Optimization of cell culture media based on statistical experimental design methodology is a widely used approach for improving cultivation conditions. We applied this methodology to refine the composition of an established culture medium for growth of a human hepatoma cell line, C3A. A selection of growth factors and nutrient supplements were systematically screened according to standard design of experiments (DoE) procedures. The results of the screening indicated that the medium additives hepatocyte growth factor, oncostatin M, and fibroblast growth factor 4 significantly influenced the metabolic activities of the C3A cell line. Surface response methodology revealed that the optimum levels for these factors were 30 ng/ml for hepatocyte growth factor and 35 ng/ml for oncostatin M. Additional experiments on primary human hepatocyte cultures showed high variance in metabolic activities between cells from different individuals, making determination of optimal levels of factors more difficult. Still, it was possible to conclude that hepatocyte growth factor, epidermal growth factor, and oncostatin M had decisive effects on the metabolic functions of primary human hepatocytes.

Dynamics of T-Junction Solution Switching Aimed at Patch Clamp Experiments.

Auzmendi, Jerónimo A; Smoler, Mariano; Moffatt, Luciano

2015-01-01

Solutions exchange systems are responsible for the timing of drug application on patch clamp experiments. There are two basic strategies for generating a solution exchange. When slow exchanges are bearable, it is easier to perform the exchange inside the tubing system upstream of the exit port. On the other hand, fast, reproducible, exchanges are usually performed downstream of the exit port. As both strategies are combinable, increasing the performance of upstream exchanges is desirable. We designed a simple method for manufacturing T-junctions (300 μm I.D.) and we measured the time profile of exchange of two saline solutions using a patch pipette with an open tip. Three factors were found to determine the timing of the solution switching: pressure, travelled distance and off-center distance. A linear relationship between the time delay and the travelled distance was found for each tested pressure, showing its dependence to the fluid velocity, which increased with pressure. The exchange time was found to increase quadratically with the delay, although a sizeable variability remains unexplained by this relationship. The delay and exchange times increased as the recording pipette moved away from the center of the stream. Those increases became dramatic as the pipette was moved close to the stream borders. Mass transport along the travelled distance between the slow fluid at the border and the fast fluid at the center seems to contribute to the time course of the solution exchange. This effect would be present in all tubing based devices. Present results might be of fundamental importance for the adequate design of serial compound exchangers which would be instrumental in the discovery of drugs that modulate the action of the physiological agonists of ion channels with the purpose of fine tuning their physiology.

Nonsymmetrical transition from reverse-saturable absorption (RSA) to saturable absorption (SA) caused by excited state absorption induced mass transport of the CuPcTs dissolved in dimethyl sulfoxide is observed in an open aperture Z-scan experiment with a 21-ps laser pulse. The nonsymmetrical transition from RSA to SA is ascribed neither to saturation of excited state absorption nor to thermal induced mass transport, the so-called Soret effect. In our consideration, strong nonlinear absorption causes the rapid accumulation of the non-uniform kinetic energy of the solute molecules. The non-uniform kinetic field in turn causes the migration of the solute molecules. Additionally, an energy-gradient-induced mass transport theory is presented to interpret the experimental results, and the theoretical calculations are also taken to fit our experimental results.

The movement of water and solute into and through the vadose zone is, in essence, an issue of immiscible displacement in pore-space network of a soil. Therefore, multiphase flow and transport in porous media, referring to three medium: air, water, and the solute, pose one of the largest unresolved challenges for porous medium fluid seepage. However, this phenomenon has always been largely neglected. It is expected that a reliable analysis model of the multi-phase flow in soil can truly reflect the process of natural movement about the infiltration, which is impossible to be observed directly. In such cases, geophysical applications of the nuclear magnetic resonance (NMR) provides the opportunity to measure the water movements into soils directly over a large scale from tiny pore to regional scale, accordingly enable it available both on the laboratory and on the field. In addition, the NMR provides useful information about the pore space properties. In this study, we proposed both laboratory and field experiments to measure the multi-phase flow parameters, together with optimize the model in computer programming based on the fractional partial differential equations (fPDE). In addition, we establish, for the first time, an infiltration model including solute flowing with water, which has huge influence on agriculture and soil environment pollution. Afterwards, with data collected from experiments, we simulate the model and analyze the spatial variability of parameters. Simulations are also conducted according to the model to evaluate the effects of airflow on water infiltration and other effects such as solute and absorption. It has significant meaning to oxygen irrigation aiming to higher crop yield, and shed more light into the dam slope stability. In summary, our framework is a first-time model added in solute to have a mathematic analysis with the fPDE and more instructive to agriculture activities.

How accurate are insights compared to analytical solutions? In four experiments, we investigated how participants’ solving strategies influenced their solution accuracies across different types of problems, including one that was linguistic, one that was visual and two that were mixed visual-linguistic. In each experiment, participants’ self-judged insight solutions were, on average, more accurate than their analytic ones. We hypothesised that insight solutions have superior accuracy because they emerge into consciousness in an all-or-nothing fashion when the unconscious solving process is complete, whereas analytic solutions can be guesses based on conscious, prematurely terminated, processing. This hypothesis is supported by the finding that participants’ analytic solutions included relatively more incorrect responses (i.e., errors of commission) than timeouts (i.e., errors of omission) compared to their insight responses.

Loss of drug content during cell culture transport experiment can lead to misinterpretations in permeability analysis. This study analyses drug adsorption to various plastic containers and drug retention in cultured cells under in vitro conditions. The loss of various drugs to polystyrene tubes and well plates was compared to polypropylene and glass tubes both in deionised water and buffer solution. In cellular uptake experiments, administered drugs were obtained from cultured cells by liquid extraction. Samples were collected at various time points and drug concentrations were measured by a new HPLC-MS/MS method. Acidic drugs (hydrochlorothiazide, naproxen, probenicid, and indomethacin) showed little if any sorption to all tested materials in either water or buffer. In the case of basic drugs, substantial loss to polystyrene tubes and well plates was observed. After 4.5 h, the relative amount remaining in aqueous test solution stored in polystyrene tubes was 64.7 +/- 6.8%, 38.4 +/- 9.1%, 31.9 +/- 6.7%, and 23.5 +/- 6.1% for metoprolol, medetomidine, propranolol, and midazolam, respectively. Interestingly, there was no significant loss of drugs dissolved in buffer to any of the tested materials indicating that buffer reduced surficial interaction. The effect of drug concentration to sorption was also tested. Results indicated that the higher the concentration in the test solution the lower the proportional drug loss, suggesting that the polystyrene contained a limited amount of binding sites. Cellular uptake studies showed considerable retention of drugs in cultured cells. The amounts of absorbed drugs in cellular structures were 0.45%, 4.88%, 13.15%, 43.80%, 23.57% and 11.22% for atenolol, metoprolol, medetomidine, propranolol, midazolam, and diazepam, respectively. Overall, these findings will benefit development and validation of further in vitro drug permeation experiments.

Full Text Available Xylogone ganodermophthora (Xg is an ascomycetous fungus that causes yellow rot on cultivated Ganoderma lucidum. Previously, we reported in vitro antifungal activities of a Xg culture extract against several watermelon pathogens. In 2014, we conducted greenhouse experiments to evaluate the control efficacy of a water extract of cultured Xg on watermelon powdery mildew (WPM. The test material (stock solution, ca. 4,000 µg/ml was prepared by an autoclaved Xg culture in water at a ratio of 800 g of culture per 6 liter of water, and then filtering it through filter paper. Six foliar applications of the solutions (diluted 100- and 1,000-fold significantly suppressed the formation of conidiophores and conidia. The inhibitory effect of aqueous potassium phosphonate solution on the disease and its phytotoxicity was tested. Phytotoxicity on watermelon plants was observed at concentrations of 1,000 and 2,000 µg/ml as irregular brownish spots. The control efficacies against WPM were 91.9% at 2,000 µg/ml, 64.9% at 1,000 µg/ml, and 62.2% at 500 µg/ml.

A new culture, Leuconostoc carnosum 4010, for biopreservation of vacuum-packed meats is described. The culture originated from bacteriocin-producing lactic acid bacteria (LAB) naturally present in vacuum-packed meat products. Approximately, 72,000 colonies were isolated from 48 different vacuum......-packed meat products and examined for antibacterial activity. Bacteriocin-producing colonies were isolated from 46% of the packages examined. Leuc. carnosum was the predominant bacteriocin-producing strain and Leuc. carnosum 4010 was selected for further experiments because it showed strong antilisterial...... activity corresponding to molecular sizes of 4.6 and 5.3 kDa. N-terminal amino acid sequencing showed that Leuc. carnosum 4010 produced two bacteriocins highly similar or identical to leucocin A and leucocin C.

The ISPyB information-management system for crystallography has been adapted to include data from small-angle X-ray scattering of macromolecules in solution experiments. Logging experiments with the laboratory-information management system ISPyB (Information System for Protein crystallography Beamlines) enhances the automation of small-angle X-ray scattering of biological macromolecules in solution (BioSAXS) experiments. The ISPyB interface provides immediate user-oriented online feedback and enables data cross-checking and downstream analysis. To optimize data quality and completeness, ISPyBB (ISPyB for BioSAXS) makes it simple for users to compare the results from new measurements with previous acquisitions from the same day or earlier experiments in order to maximize the ability to collect all data required in a single synchrotron visit. The graphical user interface (GUI) of ISPyBB has been designed to guide users in the preparation of an experiment. The input of sample information and the ability to outline the experimental aims in advance provides feedback on the number of measurements required, calculation of expected sample volumes and time needed to collect the data: all of this information aids the users to better prepare for their trip to the synchrotron. A prototype version of the ISPyBB database is now available at the European Synchrotron Radiation Facility (ESRF) beamline BM29 and is already greatly appreciated by academic users and industrial clients. It will soon be available at the PETRA III beamline P12 and the Diamond Light Source beamlines I22 and B21

The ISPyB information-management system for crystallography has been adapted to include data from small-angle X-ray scattering of macromolecules in solution experiments. Logging experiments with the laboratory-information management system ISPyB (Information System for Protein crystallography Beamlines) enhances the automation of small-angle X-ray scattering of biological macromolecules in solution (BioSAXS) experiments. The ISPyB interface provides immediate user-oriented online feedback and enables data cross-checking and downstream analysis. To optimize data quality and completeness, ISPyBB (ISPyB for BioSAXS) makes it simple for users to compare the results from new measurements with previous acquisitions from the same day or earlier experiments in order to maximize the ability to collect all data required in a single synchrotron visit. The graphical user interface (GUI) of ISPyBB has been designed to guide users in the preparation of an experiment. The input of sample information and the ability to outline the experimental aims in advance provides feedback on the number of measurements required, calculation of expected sample volumes and time needed to collect the data: all of this information aids the users to better prepare for their trip to the synchrotron. A prototype version of the ISPyBB database is now available at the European Synchrotron Radiation Facility (ESRF) beamline BM29 and is already greatly appreciated by academic users and industrial clients. It will soon be available at the PETRA III beamline P12 and the Diamond Light Source beamlines I22 and B21.

2017-04-01

A number of adverse events in Australia and overseas have highlighted the need to examine the workplace culture in the maternity environment. Little attention has been paid to the midwifery workplace culture in Australia. The study aimed to explore the midwifery workplace culture from the perspective of midwives themselves. A qualitative descriptive design was used. Group and individual interviews were undertaken of urban, regional and rural-based midwives in Australia. Data were analysed thematically. The study showed that both new and experienced midwives felt frustrated by organisational environments and attitudes, and expressed strategies to cope with this. Five themes were identified from the data. These were: Bullying and resilience, Fatigued and powerless midwives, Being 'hampered by the environment', and The importance of support for midwifery. The study discusses the themes in depth. In particular, discussion focusses on how midwifery practise was affected by midwives' workplace culture and model of care, and the importance of supportive relationships from peers and managers. This study illuminated both positive and negative aspects of the midwifery workplace culture in Australia. One way to ensure the wellbeing and satisfaction of midwives in order to maintain the midwifery workforce and provide quality care to women and their families is to provide positive workplace cultures.

From Awareness to Cultural Agency: EFL Colombian Student Teachers’ Travelling Abroad Experiences

Directory of Open Access Journals (Sweden)

John Jairo Viafara González

2015-01-01

Full Text Available Colombian English as a foreign language student teachers’ opportunities to grow as educators through international sojourns do not usually subsume the traditional study and residence abroad goal. This was the case for our participants who engaged mainly in working abroad with study being ancillary. Fifty student teachers from two public universities reported how their international sojourn bolstered their intercultural learning. Three different programs, disconnected from participants’ academic institutions, became vehicles for their experiences abroad. Surveys and interviews reveal that participants’ origin, selected programs, and contextual circumstances influenced their intercultural learning. As a result, intercultural development gravitated towards awareness of intercultural patterns, critical reading of culture, and pre-service teachers’ repositioning to build cultural agency. Implications suggest the need to connect traveling abroad programs to undergraduate curricula.

Chae, Duckhee; Lee, Jina; Asami, Keiko; Kim, Hyunlye

2018-05-01

This study explored the experiences of public health workers (PHWs) providing health care for migrants living in Korea and clarified needs for cultural competence training. Twenty-six PHWs from five public health centers in Gwangju city, South Korea, participated in this exploratory qualitative study. Five semi-structured focus group interviews of PHWs were conducted from September to December 2016. A directed content analysis approach was conducted using four categories: perceived characteristics of migrants, interaction between PHWs and migrants, interaction between PHWs and organizations/systems, and cultural competence training needs. PHWs perceived that migrants lacked autonomy in health decisions and awareness of health behaviors. PHWs experienced difficulties in communicating and in establishing trusting relationships. They found clients hard to reach and easy to miss, a lack of continuity in health care programs, and inadequate human and material resources. They preferred passive teaching methods to activity-based simulation. PHWs believed essential training should be provided through e-learning to all PHWs, including management. PHWs reported experiencing multiple challenges from a lack of preparedness for culturally competent care and their clients' vulnerability. Development of cultural competence training is suggested through e-learning that reflects the PHWs' experiences and provides systematic support. © 2018 Wiley Periodicals, Inc.

How to engage the public in a reflection on the most pressing ethical issues of our time? What if part of the solution lies in adopting an interdisciplinary and collaborative strategy to shed light on critical issues in bioethics? An example is Art + Bioéthique, an innovative project that brought together bioethicists, art historians and artists with the aim of expressing bioethics through arts in order to convey the "sensitive" aspect of many health ethics issues. The aim of this project was threefold: 1) to identify and characterize mechanisms for the meeting of arts and bioethics; 2) to experiment with and co-construct a dialogue between arts and bioethics; and 3) to initiate a public discussion on bioethical issues through the blending of arts and bioethics. In connection with an exhibition held in March 2016 at the Espace Projet, a non-profit art space in Montréal (Canada), the project developed a platform that combined artworks, essays and cultural & scientific mediation activities related to the work of six duos of young bioethics researchers and emerging artists. Each duo worked on a variety of issues, such as the social inclusion of disabled people, the challenges of practical applications of nanomedicine and regenerative medicine, and a holistic approach to contemporary diseases. This project, which succeeded in stimulating an interdisciplinary dialogue and collaboration between bioethics and arts, is an example of an innovative approach to knowledge transfer that can move bioethics reflection into the public space. © 2017 John Wiley & Sons Ltd.

Cultural effects on mindreading.

Perez-Zapata, Daniel; Slaughter, Virginia; Henry, Julie D

2016-01-01

People from other cultural backgrounds sometimes seem inscrutable. We identified a potential cause of this phenomenon in two experiments demonstrating that adults' mental state inferences are influenced by the cultural identity of the target. We adapted White, Hill, Happé, and Frith's (2009) Strange Stories to create matched intra-cultural and cross-cultural mindreading and control conditions. Experiment 1 showed that Australian participants were faster to respond and received higher scores in the intra-cultural mindreading condition relative to the cross-cultural mindreading condition, but performance in the control conditions was equivalent. Experiment 2 replicated this pattern in independent samples of Australian and Chilean participants. These findings have important implications for cross-cultural communication and understanding.

Few studies have examined the role of culture in a woman's experience of postpartum mood problems (PPMP). This study explored differences and similarities in experiences of PPMP between first- and second-generation Canadian women. In this exploratory qualitative study, we interviewed nine first-generation and eight second-generation women who were clients of the Women's Health Centre at St. Joseph's Health Centre in Toronto, Canada. Using semistructured interviews, we explored how women perceived and experienced PPMP. Four themes reflected cultural issues: PPMP stigma, relationship with parents/in-laws, internalization of society's expectations of motherhood, and identity issues/relationship with self. The results of this study contribute to a limited literature on possible contributing factors to PPMP and can inform development of resources for delivering culturally appropriate mental health care for women dealing with PPMP.

Modelling solute dispersion in periodic heterogeneous porous media: Model benchmarking against intermediate scale experiments

Science.gov (United States)

Majdalani, Samer; Guinot, Vincent; Delenne, Carole; Gebran, Hicham

2018-06-01

This paper is devoted to theoretical and experimental investigations of solute dispersion in heterogeneous porous media. Dispersion in heterogenous porous media has been reported to be scale-dependent, a likely indication that the proposed dispersion models are incompletely formulated. A high quality experimental data set of breakthrough curves in periodic model heterogeneous porous media is presented. In contrast with most previously published experiments, the present experiments involve numerous replicates. This allows the statistical variability of experimental data to be accounted for. Several models are benchmarked against the data set: the Fickian-based advection-dispersion, mobile-immobile, multirate, multiple region advection dispersion models, and a newly proposed transport model based on pure advection. A salient property of the latter model is that its solutions exhibit a ballistic behaviour for small times, while tending to the Fickian behaviour for large time scales. Model performance is assessed using a novel objective function accounting for the statistical variability of the experimental data set, while putting equal emphasis on both small and large time scale behaviours. Besides being as accurate as the other models, the new purely advective model has the advantages that (i) it does not exhibit the undesirable effects associated with the usual Fickian operator (namely the infinite solute front propagation speed), and (ii) it allows dispersive transport to be simulated on every heterogeneity scale using scale-independent parameters.

Undergraduate students' development of social, cultural, and human capital in a networked research experience

Science.gov (United States)

Thompson, Jennifer Jo; Conaway, Evan; Dolan, Erin L.

2016-12-01

Recent calls for reform in undergraduate biology education have emphasized integrating research experiences into the learning experiences of all undergraduates. Contemporary science research increasingly demands collaboration across disciplines and institutions to investigate complex research questions, providing new contexts and models for involving undergraduates in research. In this study, we examined the experiences of undergraduates participating in a multi-institution and interdisciplinary biology research network. Unlike the traditional apprenticeship model of research, in which a student participates in research under the guidance of a single faculty member, students participating in networked research have the opportunity to develop relationships with additional faculty and students working in other areas of the project, at their own and at other institutions. We examined how students in this network develop social ties and to what extent a networked research experience affords opportunities for students to develop social, cultural, and human capital. Most studies of undergraduate involvement in science research have focused on documenting student outcomes rather than elucidating how students gain access to research experiences or how elements of research participation lead to desired student outcomes. By taking a qualitative approach framed by capital theories, we have identified ways that undergraduates utilize and further develop various forms of capital important for success in science research. In our study of the first 16 months of a biology research network, we found that undergraduates drew upon a combination of human, cultural, and social capital to gain access to the network. Within their immediate research groups, students built multidimensional social ties with faculty, peers, and others, yielding social capital that can be drawn upon for information, resources, and support. They reported developing cultural capital in the form of learning to

2016-01-01

In Korea, a regulatory oversight program of safety culture was launched in 2012 to establish regulatory measures against several events caused by weak safety culture in the nuclear industry. This paper is intended to introduce the preliminary regulatory oversight framework, development and validation of safety culture components, pilot safety culture inspection results and lessons learned. The safety culture model should be based on a sound understanding of the national culture and industry characteristics where the model will be applied. The nuclear safety culture oversight model is being developed and built on the Korean regulatory system to independently assess the nuclear power operating organizations’ safety culture.

Four sets of micromodel nonreactive solute transport experiments were conducted with flow velocity, grain diameter, pore-aspect ratio, and flow focusing heterogeneity as the variables. The data sets were offered to pore-scale modeling groups to test their simulators. Each set consisted of two learning experiments, for which all results was made available, and a challenge experiment, for which only the experimental description and base input parameters were provided. The experimental results showed a nonlinear dependence of the dispersion coefficient on the Peclet number, a negligible effect of the pore-aspect ratio on transverse mixing, and considerably enhanced mixing due to flow focusing. Five pore-scale models and one continuum-scale model were used to simulate the experiments. Of the pore-scale models, two used a pore-network (PN) method, two others are based on a lattice-Boltzmann (LB) approach, and one employed a computational fluid dynamics (CFD) technique. The learning experiments were used by the PN models to modify the standard perfect mixing approach in pore bodies into approaches to simulate the observed incomplete mixing. The LB and CFD models used these experiments to appropriately discretize the grid representations. The continuum model use published non-linear relations between transverse dispersion coefficients and Peclet numbers to compute the required dispersivity input values. Comparisons between experimental and numerical results for the four challenge experiments show that all pore-scale models were all able to satisfactorily simulate the experiments. The continuum model underestimated the required dispersivity values and, resulting in less dispersion. The PN models were able to complete the simulations in a few minutes, whereas the direct models needed up to several days on supercomputers to resolve the more complex problems.

Finger Pricks and Blood Vials: How doctors medicalize 'cultural' solutions to demedicalize the 'broken' hymen in the Netherlands.

Science.gov (United States)

Ayuandini, Sherria

2017-03-01

This paper provides new perspectives on the scholarship on medicalization and demedicalization, building on an ethnography of hymenoplasty consultations in the Netherlands. By examining how doctors can play an active role in demedicalization, this paper presents novel insights into Dutch physicians' attempt to demedicalize the "broken" hymen. In their consultations, Dutch doctors persuade hymenoplasty patients to abandon the assumed medical definition of the "broken" hymen and offer nonmedical solutions to patients' problems. Drawing from unique ethnographical access from 2012 to 2015 to 70 hymenoplasty consultations in the Netherlands, this paper's original contribution comes from closely examining how demedicalization can be achieved through the process of medicalization. It investigates how Dutch physicians go even further in their efforts to demedicalize by medicalizing "cultural" solutions as an alternative course of action to surgery.

Full Text Available How much important and fundamental instruments, formation and information methods, different from the traditional ones in the different fields of human and experimental sciences, are today and will be in the future, is highlightened in this article. According to this, some problems typical of our instructive institutions (such as universities, public administrations, factories and their relevant possible solutions are underlined. These solutions can be achieved thanks to the introduction of the "e-learning" i.e. the possibility of learning through the web. It is important to note that the usage of data processing systems and telecom technologies could improve the access to the learning resources and to meet the different requirements. A case that can be considered emblematic, with reference to our specific experience, is represented by the cultural heritage field and by the university teledidactic and telecom courses as "Cultural heritage Operator".

In order to stimulate the criticality characteristics of a dissolver in a reprocessing plant, a critical experiment program of heterogeneous cores is under going at a Static Critical Experimental Facility, STACY in Japan Atomic Energy Research Institute, JAERI. The experimental system is composed of 5w/o enriched PWR-type fuel rod array immersed in 6w/o enriched uranyl nitrate solution. First series of experiments are basic benchmark experiments on fundamental critical data in order to validate criticality calculation codes for 'general-form system' classified in the Japanese Criticality Safety Handbook, JCSHB. Second series of experiments are concerning the neutron absorber effects of fission products related to the burn-up credit Level-2. For demonstrating the reactivity effects of fission products, reactivity effects of natural elements such as Sm, Nd, Eu and 103 Rh, 133 Cs, solved in the nitrate solution are to be measured. The objective of third series of experiments is to validate the effect of gadolinium as a soluble neutron poison. Properties of temperature coefficients and kinetic parameters are also studied, since these parameters are important to evaluate the transient behavior of the criticality accident. (author)

Decentralized cogeneration - A solution for Romania? RAEF experience

deficit should be covered using indigenous power generation sources. One could conclude, correlated with the previous discussion on financing investment, that most of the private capital is expected in the power and heat generation sector. New injection points might necessitate network reinforcement (implying additional costs and delays), may have to pass a complicated and lengthy authorizations process, etc. In conclusion, realisation of 'greenfield' large projects is likely to be cumbersome and delayed due mainly to issues related to connection to the grid. But also fuel supply issues, cooling water access, impact on communities, add to the serious siting problems for new greenfield power generation projects. A psychological impact on private investor's appetite is also given by the continuation of erection of Cernavoda 2, (3?) nuclear units, as these are modern, safe, and optimal at dispatching. In conclusion, in Romania, at present, one cannot identify large private power generation projects in advanced development phase. A solution could be decentralized power generation. Combined with covering a heat demand, it leads to distributed cogeneration. It is an EU and worldwide trend. The above, combined with the overall analysis of the experience in Romania and worldwide allow drawing the following conclusions: - Decentralised generation (cogeneration) is a solution to be considered for Romania and for the region; - The national energy strategy must consider it; - Resources should be allocated to it (not necessarily financial), thus contributing to sustainable development; - It must be promoted by appropriate legislative, regulatory fiscal, etc framework; - Periodic exchange of experience among different actors is decisive for avoiding wasting resources; - this is mainly the purpose of the present article; - Private initiative is the main driver and must be encouraged for promoting efficiency and sustainability; - The solution chosen yields better risk management while

Argonne is assisting SHINE Medical Technologies in developing SHINE, a system for producing fission-product ⁹⁹Mo using a D/T-accelerator to produce fission in a non-critical target solution of aqueous uranyl sulfate. We have developed an experimental setup for studying thermal-hydraulics and bubble formation in the uranyl sulfate solution to simulate conditions expected in the SHINE target solution during irradiation. A direct electron beam from the linac accelerator will be used to irradiate a 20 L solution (sector of the solution vessel). Because the solution will undergo radiolytic decomposition, we will be able to study bubble formation and dynamics and effects of convection and temperature on bubble behavior. These experiments will serve as a verification/ validation tool for the thermal-hydraulic model. Utilization of the direct electron beam for irradiation allows homogeneous heating of a large solution volume and simplifies observation of the bubble dynamics simultaneously with thermal-hydraulic data collection, which will complement data collected during operation of the miniSHINE experiment. Irradiation will be conducted using a 30-40 MeV electron beam from the high-power linac accelerator. The total electron-beam power will be 20 kW, which will yield a power density on the order of 1 kW/L. The solution volume will be cooled on the front and back surfaces and central tube to mimic the geometry of the proposed SHINE solution vessel. Also, multiple thermocouples will be inserted into the solution vessel to map thermal profiles. The experimental design is now complete, and installation and testing are in progress.

We establish the existence of travelling wave solutions for delayed cooperative recursions that are allowed to have more than two equilibria. We define an important extended real number that is used to determine the speeds of travelling wave solutions. The results can be applied to a large class of delayed cooperative reaction–diffusion models. We show that for a delayed Lotka–Volterra reaction–diffusion competition model, there exists a finite positive number c * + that can be characterized as the slowest speed of travelling wave solutions connecting two mono-culture equilibria or connecting a mono-culture with the coexistence equilibrium

While in general arousal increases with positive or negative valence (a so-called V-shaped relation), there are large differences among individuals in how these two fundamental dimensions of affect are related in people's experience. In two studies, we examined two possible sources of this variation: personality and culture. In Study 1, participants (Belgian university students) recalled a recent event that was characterized by high or low valence or arousal and reported on their feelings and their personality in terms of the Five-Factor Model. In Study 2, participants from Canada, China/Hong Kong, Japan, Korea, and Spain reported on their feelings in a thin slice of time and on their personality. In Study 1, we replicated the V-shape as characterizing the relation between valence and arousal, and identified personality correlates of experiencing particular valence-arousal combinations. In Study 2, we documented how the V-shaped relation varied as a function of Western versus Eastern cultural background and personality. The results showed that the steepness of the V-shaped relation between valence and arousal increases with Extraversion within cultures, and with a West-East distinction between cultures. Implications for the personality-emotion link and research on cultural differences in affect are discussed. © 2016 Wiley Periodicals, Inc.

Current uncertainty for the future of the health care landscape is placing an increasing amount of pressure on leadership teams to be prepared to steer their organization forward in a number of potential directions. It is commonly recognized among health care leaders that culture will either enable or disable organizational success. However, very few studies empirically link culture to health care-specific performance outcomes. Nearly every health care organization in the US specifies its cultural aspirations through mission and vision statements and values. Ambitions of patient-centeredness, care for the community, workplace of choice, and world-class quality are frequently cited; yet, little definitive research exists to quantify the importance of building high-performing cultures. Our study examined the impact of cultural attributes defined by a culture index (Cronbach's alpha = 0.88) on corresponding performance with key health care measures. We mapped results of the culture index across data sets, compared results, and evaluated variations in performance among key indicators for leaders. Organizations that perform in the top quartile for our culture index statistically significantly outperformed those in the bottom quartile on all but one key performance indicator tested. The culture top quartile organizations outperformed every domain for employee engagement, physician engagement, patient experience, and overall value-based purchasing performance with statistical significance. Culture index top quartile performers also had a 3.4% lower turnover rate than the bottom quartile performers. Finally, culture index top quartile performers earned an additional 1% on value-based purchasing. Our findings demonstrate a meaningful connection between performance in the culture index and organizational performance. To best impact these key performance outcomes, health care leaders should pay attention to culture and actively steer workforce engagement in attributes that

Our study examined the impact of cultural attributes defined by a culture index (Cronbach’s alpha = 0.88) on corresponding performance with key health care measures. We mapped results of the culture index across data sets, compared results, and evaluated variations in performance among key indicators for leaders. Organizations that perform in the top quartile for our culture index statistically significantly outperformed those in the bottom quartile on all but one key performance indicator tested. The culture top quartile organizations outperformed every domain for employee engagement, physician engagement, patient experience, and overall value-based purchasing performance with statistical significance. Culture index top quartile performers also had a 3.4% lower turnover rate than the bottom quartile performers. Finally, culture index top quartile performers earned an additional 1% on value-based purchasing. Our findings demonstrate a meaningful connection between performance in the culture index and organizational performance. To best impact these key performance outcomes, health care leaders should pay attention to culture and actively steer workforce engagement in attributes that

Overinclusive authorship practices such as honorary or guest authorship have been widely reported, and they appear to be exacerbated by the rise of large interdisciplinary collaborations that make authorship decisions particularly complex. Although many studies have reported on the frequency of honorary authorship and potential solutions to it, few have probed how the underlying dynamics of large interdisciplinary teams contribute to the problem. This article reports on a qualitative study of the authorship standards and practices of six National Science Foundation-funded interdisciplinary environmental science teams. Using interviews of the lead principal investigator and an early-career member on each team, our study explores the nature of honorary authorship practices as well as some of the motivating factors that may contribute to these practices. These factors include both structural elements (policies and procedures) and cultural elements (values and norms) that cross organizational boundaries. Therefore, we provide recommendations that address the intersection of these factors and that can be applied at multiple organizational levels.

To test the effect of different vitrification solutions and procedures on the morphology of human preantral follicles. Pilot study. Gynecology research unit in a university hospital. Ovarian biopsies were obtained from nine women aged 22-35 years. Ovarian tissue fragments were subjected to [1] different vitrification solutions to test their toxicity or [2] different vitrification methods using plastic straws, medium droplets, or solid-surface vitrification before in vitro culture. Number of morphologically normal follicles after toxicity testing or vitrification with the different treatments determined by histologic analysis. In the toxicity tests, only VS3 showed similar results to fresh tissue before and after in vitro culture (fresh controls 1 and 2). In addition, this was the only solution able to completely vitrify. In all vitrification procedures, the percentage of normal follicles was lower than in controls. However, of the three protocols, the droplet method yielded a significantly higher proportion of normal follicles. Our experiments showed VS3 to have no deleterious effect on follicular morphology and to be able to completely vitrify, although vitrification procedures were found to affect human follicles. Nevertheless, the droplet method resulted in a higher percentage of morphologically normal follicles. Copyright © 2011 American Society for Reproductive Medicine. Published by Elsevier Inc.

Korea and Japan are geographically very close, and a variety of cultural exchanges have taken place in recorded history. However, Korea and Japan have been enriched by the influence of Western cultures along with modernization, and mutual exchanges between the two countries have thus decreased in numerous fields including mental health and psychiatry. Prof. Masahisa Nishizono and Prof. Byun-Kun Min, who are leaders in the field of psychiatry in both Japan and Korea, have established "The Joint Workshop for Psychiatric Residents of Korea and Japan", which has been held alternately in Fukuoka or Seoul every summer since 2000. This Joint Workshop provides young psychiatrists with real experiences and many opportunities to learn about transcultural psychiatry regarding both countries. The participants are able to obtain a better mutual understanding of psychiatric epidemiology, recent developments in biological psychiatry while also learning about different concepts regarding the stigma of mental disorders. All participants could also increase their knowledge about the traditional culture and social changes related to the field of psychiatry in both countries. The workshop has helped to build friendship and mutual cooperation between both nations. Contemporary societies are continually becoming more and more diversified and complicated. For young psychiatrists who have to treat patients with modern difficulties and various complicated problems, such cross-cultural experiences may be useful for establishing potentially new and effective treatments for such patients. Psychiatrists and mental health experts have tried to reduce of stigma and discrimination against people with mental disorders, but even today such stigma and discrimination continues to strongly exist. The author thinks that such cross-cultural experiences by the psychiatrists themselves may help to reduce such notions. The author would like to explore the role of cross-cultural experiences in the field of

The purpose of this study was to examine the "lived experience" of Asian Indian (AI)-White couples in interracial marriages. Ten highly educated AI-White professional couples were individually interviewed about their subjective experience of being in an interracial marriage, the challenges and strengths of this marriage, and the potential role of culture in their marriages. Data were analyzed using the Consensual Qualitative Research methodology. Results indicated that the couples' marital experiences were influenced by a complex intersection of ecosystemic factors with significant psychological impacts. These findings highlight shortcomings in drawing simplistic conclusions regarding the success or failure of an interracial marriage and have important implications for theory, research, and clinical practice. 2011 © FPI, Inc.

2014-01-01

This article discuss the interaction of siderophores (which are low molecular weight, secreted metabolites) of microorganisms (Pseudomonas stutzeri) separately and simultaneously with Cu metal in the solution culture on the roots of 4d old seedlings of Vigna radiata. Naturally occurring bacteria play an important role in plant growth due to the release of pigment. It is a coloring compound (siderophore) showed high chemical oxygen demand (COD), lowers the pressure of oxygen. This lowers the nutrient uptake by the roots due to which reduced plant growth with metabolic disorder was observed in the whole plant. A wide range of phenomena from simple to complex interactions was observed between microorganisms and Cu metal in relation with plant root growth such as adsorption, oxidation/reduction of pigment, solubilization. Results showed that microbial strain showed a significant effect on weight of root in aqueous culture whereas nutrient medium support the root growth. Biochemical analysis reflects that lipids were main target of both abiotic and biotic stress that may utilizes to overcome the stress due to which protein contents were seemed to be unaffected at highest concentration of metal or it may also be related with the degradation of lipids due to the biotic and abiotic stress.

Full Text Available Background: Chitosan, a linear polysaccharide, has been recently used in biomedical applications. In vitro studies have demonstrated its effect on cellular growth and its stimulatory action on cellular layer formation. Aims: The present study aims to compare the proliferative effects of chitosan in two forms, membranous and solution forms, on Swiss 3T3 mouse embryonic fibroblasts. Study Design: In vitro study. Methods: Three experimental groups were formed: cells were cultured in a normal medium without chitosan (Control Group; cells were cultured either in a medium containing 2.0% chitosan in membranous form (Membrane Group or chitosan solution at a concentration of 2.0% (Solution Group.Two different methods were used in the experiments: cells cultured on the medium containing chitosan in solution or membranous forms (method 1; and chitosan solution or membranous forms were added into the medium containing previously cultured cells (method 2. Results: Scanning electron microscopic investigations of the experimental groups revealed cells with well-defined cellular projections, intact cellular membranes and tight intercellular junctions. They were especially prominent in the membrane group of method 1 and in the membrane and solution groups of method 2. Mouse monoclonal anti-collagen 1 primary antibody was used to indicate collagen synthesis. Prominent collagen synthesis was detected in the membrane groups on the 10th day of culture for both methods. Bromodeoxyuridine (BrdU and MTT assays were performed in order to assess cellular proliferation and viability, respectively. BrdU labelling tests indicated a higher proliferation index in the membrane group of method 1 on the 5th and 10th days. For the second method, the membranous form on the 10th day and solution form on the 5th day were the most effective groups in terms of cellular proliferation. MTT results reflected a high cellular viability in method 1 on the 5th day of treatment with the

Modern Warfighters often find themselves in a variety of non-combat roles such as negotiator, peacekeeper, reconstruction, and disaster relief. They are expected to perform these roles within a culture alien to their own. Each individual they encounter brings their own set of values to the interaction that must be understood and reconciled. To navigate the human terrain of these complex interactions, the Warfighter must not only consider the specifics of the target culture, but also identify the stakeholders, recognize the influencing cultural dimensions, and adapt to the situation to achieve the best possible outcome. Vcom3D is using game-based scenarios to develop culturally adaptive competency. The avatars that represent the stakeholders must be able to portray culturally accurate behavior, display complex emotion, and communicate through verbal and non-verbal cues. This paper will discuss the use of emerging game technologies to better simulate human behavior in cross-cultural dilemmas.

Studying electrochemical (EC) processes with electron microscopes offers the possibility of achieving much higher resolution imaging of nanoscale processes in real time than with optical microscopes. We have developed a vacuum sealed liquid sample electrochemical cell with electron transparent windows, microelectrodes and an electrochemical reference electrode. The system, called the EC-SEM Cell, is used to study electrochemical reactions in liquid with a standard scanning electron microscope (SEM). The central component is a microfabricated chip with a thin (50 nm) Si-rich silicon nitride (SiNx) window with lithographically defined platinum microelectrodes. We show here the design principles of the EC-SEM system, its detailed construction and how it has been used to perform a range of EC experiments, two of which are presented here. It is shown that the EC-SEM Cell can survive extended in-situ EC experiments. Before the EC experiments we characterized the beam current being deposited in the liquid as this will affect the experiments. The first EC experiment shows the influence of the electron-beam (e-beam) on a nickel solution by inducing electroless nickel deposition on the window when increasing the current density from the e-beam. The second experiment shows electrolysis in EC-SEM Cell, induced by the built-in electrodes. - Highlights: • New in-situ SEM system for electrochemistry. • In-situ Beam current measurements through liquid. • In-situ SEM E-beam-induced electroless deposition of Ni. • In-situ electrolysis

Nutrient supply and waste removal in porous tissue engineering scaffolds decrease from the periphery to the center, leading to limited depth of ingrowth of new tissue into the scaffold. However, as many tissues experience cyclic physiological strains, this may provide a mechanism to enhance solute transport in vivo before vascularization of the scaffold. The hypothesis of this study was that pore cross-sectional geometry and interconnectivity are of major importance for the effectiveness of cyclic deformation-induced solute transport. Transparent elastic polyurethane scaffolds, with computer-programmed design of pore networks in the form of interconnected channels, were fabricated using a 3D printing and injection molding technique. The scaffold pores were loaded with a colored tracer for optical contrast, cyclically compressed with deformations of 10 and 15% of the original undeformed height at 1.0 Hz. Digital imaging was used to quantify the spatial distribution of the tracer concentration within the pores. Numerical simulations of a fluid-structure interaction model of deformation-induced solute transport were compared to the experimental data. The results of experiments and modeling agreed well and showed that pore interconnectivity heavily influences deformation-induced solute transport. Pore cross-sectional geometry appears to be of less relative importance in interconnected pore networks. Validated computer models of solute transport can be used to design optimal scaffold pore geometries that will enhance the convective transport of nutrients inside the scaffold and the removal of waste, thus improving the cell survivability deep inside the scaffold.

Full Text Available The article examines the applications aspects of cultural landscape for the preparation of the classical performing arts staging. Research findings highlighted that the cultural landscape (parks, estates, castles, bastions, etc. objects occupies an increasingly important role in public recreation and classical art development programs. At the same time it is noted that event’s aesthetic and emotional quality suffers due to the fact that no specific attention was given for the preparation of the event space. More methodological materials are necessary for preparation of this type of design spaces. In Lithuania classical performing arts events in cultural landscape open spaces are based on XVI–XVII century tradition and has good prospects for modern development. A review of some of the classical art events installations, based on the importance of quality of open spaces influence on the emotional impact, that should be an integral part of the cultural event. The author summarizes his experience of ballet events in open spaces in the cultural landscape – Klaipėda, Trakai. Presented is Tchaikovsky's ballet “Swan Lake” construction in Klaipėda John Hill project that includes infrastructure and environmental design concept: audience space, stage design, stage design performance solutions. Analogous key decisions are later adapted to the ballet performance in the natural environment of the lake Trakai. Experience of this project dictated the necessity of deeper understanding and methodological basis for the classical performing arts analysis and design.

The effect of varying K supply on 137 Cs uptake by lettuce (Lactuca sativa, cv. Batavia, Gloire du Dauphine) was studied in solution culture, in a potted soil experiment and in a greenhouse lysimeter experiment under close-to-real conditions. Lettuce was grown for 13 days in nutrient solution spiked with 137 Cs. Treatments were four concentrations of potassium in solution (25, 50, 250, and 1000 μM). Yields were marginally affected by K supply. The 137 Cs concentration factor (CF, ml/g) decreased 66-fold in the shoot and 432-fold in the roots over the whole K concentration range. The decrease was most pronounced between 25 and 250 μM K. In a subsequent experiment, lettuce was grown for 20 days under the same climatic conditions in two sandy-foam soils (A, B) contaminated with 134 Cs. Both had similar characteristics but differed widely in K supply. Soil solution K concentrations were 100 μM (A) or 3000 μM (B). The radiocesium soil-to-plant Transfer Factor (TF, g plant dry weight / g soil) was 0.320 in soil A and 0.016 in soil B. The higher 137 Cs availability at the lower K supply (soil A) was contrasted by lower 137 Cs concentrations in soil solution of soil A than of soil B. Radiocesium transfer to lettuce grown to maturity was analysed on 5 different lysimeter soils under controlled climatic conditions. The soils were artificially contaminated with 137 Cs in 1994. The TF's varied between 0.032 and 0.191 and were not related to K concentrations in soil solution. The CF decreased about 100-fold with K concentrations increasing from 0.3 to 18 mM. Predictions of soil-to-plant transfer factors based on soil solution composition and nutrient solution results were qualitatively correct but underestimated the observed values

A simple computational for the analysis of 2-D solute migration experiments

A preliminary model for the simulation of 2-D migration patterns is presented. This computer model adopts a novel approach to the solution of the advection-dispersion equation in two dimensions through finite differences. The soil column is divided into a number of thin columns. The 1-D advection-dispersion equation is applied in the direction of flow and, using the same time increment, the 1-D diffusion equation is applied perpendicularly to the flow. The results thus obtained were compared to those of two migration experiments with two different soils. (author)

Humour, beauty, and culture as personal health resources: experiences of elderly Swedish women.

2007-01-01

This paper explores how a group of elderly women used humour, beauty, and cultural activities to maintain physical and mental well-being. The paper reports on one aspect of a qualitative study on women's work and health in a lifetime perspective. Interviews with 20 strategically selected Swedish women, aged 63 to 83 years, were audiotaped and analysed according to a phenomenological approach. During the interview process, the researchers became increasingly aware that the women had clear ideas about what enabled them to feel well and healthy - even when actually quite diseased. Creating and enjoying humour, beauty, and culture formed part of such strategies. Joking with workmates made hard, low-status jobs easier, helped them endure pain, and helped balance marital difficulties. Creating a nice and comfortable home gave pleasure and a little luxury in a life filled with necessities. Making articles for everyday use more beautiful was regarded as worthwhile, because it gave delight to them and their families. Gains from cultural activities were social, aesthetic, and existential - the latter through a feeling of self-recognition and being heard. Humour, beauty, and culture formed a greater part of these women's survival strategies than expected. Making everyday life more aesthetic is an undervalued aspect of women's health-creating work in the family. Through their lifelong experience as carers and homemakers, elderly women possess special knowledge regarding what may promote health, a knowledge that should be tapped. When supplying elderly women with social care, their needs for humour, beauty, and culture should be respected.

Perez, S.

2002-01-01

Promoting and Evaluating Safety Culture (S.C.) in Operating Organizations must be one of the main Nuclear Regulator goals to achieve. This can be possible only if each and every one of the regulatory activities inherently involves S.C. It can be seen throughout attitudes, values, uses and practices in both individuals and the whole regulatory organization. One among all the regulatory tools commonly used by regulators to promote and evaluate the commitment of the licensees with safety culture as a whole involves organizational factors and particular attention is directed to the operating organization. This entailed a wide range of activities, including all those related with management of safety performance. Operating Experience Feedback Programme as a tool to enhance safety operation is particularly useful for regulators in the evaluation of the role of S.C. in operating organization. Safety Culture is recognized as a subset of the wider Organizational Culture. Practices that improve organizational effectiveness can also contribute to enhance safety. An effective event investigation methodology is a specific practice, which contributes to a healthy Safety Culture. (author)

The need to consider the Middle East as a group of distinct countries and not as one single market and to tailor the services offered by companies is stressed. The cultures, political and social conditions, forms of the oil and gas industry in the countries making up the Middle East and their technology requirements are different and vary widely. The approach taken by Shell Global Solutions to these differences is described and illustrated with Shell's experiences in Oman and Saudi Arabia. Shell has found that Omanis are keen to work in their oil and gas industry, and to protect their country's natural environment. Saudi also have intense pride in their oil industry and here Shell supports refinery operators reduce costs while maintaining strict quality control. Shell has been selected to help Saudi Arabia develop its natural gas reserves; as part of the Core Venture 3 project, Shell will build a power desalination plant

Interaction between U(VI) and Fe(II) in aqueous solution under anaerobic conditions. Closed system experiments

International Nuclear Information System (INIS)

Myllykylae, E.; Ollila, K.

2011-01-01

The aim of these experiments is to investigate the potential reduction of U(VI) carbonate and hydroxide complexes by aqueous Fe(II). This reduction phenomenon could be important under the disposal conditions of spent fuel. If groundwater enters the copper/iron canister, alpha radiolysis of the water may locally induce oxidizing conditions on the surface of UO 2 fuel, leading to the dissolution of UO 2 as more soluble U(VI) species. A potential reducing agent in the intruding water is Fe(II)(aq) from anaerobic corrosion of the copper/iron canister. The reduction of U(VI) to U(IV) would substantially decrease the solubility of U as well as co-precipitate other actinides and radionuclides. The interaction experiments were conducted in 0.01 M NaCl and 0.002 M NaHCO 3 solutions using an initial uranium concentration of either 8.4 x 10 -8 or 4.2 x 10 -7 mol/L with an initial Fe(II) concentration of 1.8 x 10 -6 in the NaCl solutions and 1.3 x 10 -6 mol/L in the NaHCO 3 solutions. Only after an equilibration period for U(VI) complexation was Fe(II) added to the solutions. The reaction times varied from 1 week to 5 months. For extra protection against O 2 , even inside a glove-box (N 2 atmosphere), the plastic reaction vessels were closed in metallic containers. The concentrations of U, Fe TOT and Fe(II) were analysed as a function of time for unfiltered, micro- and ultrafiltered samples. In addition, the precipitate on the ultrafilters was analysed with ESEM-EDS. The evolution of pH and Eh values was measured. The oxidation state of U in solution was preliminarily analysed for chosen periods. The results of the tests in 0.01 M NaCl showed an initial rapid decrease in U concentration after the addition of Fe(II) to the solution. The U found on test vessel walls at the end of the reaction periods, as well as the ESEM-EDS analyses of the filtered precipitates from the test solutions, showed that precipitation of U had occurred. The oxidation state analyses showed the presence

Whilst striving to create a balanced and healthy life, individuals experience challenges across their life span. Spirituality can contribute to mental health and well-being, as can cultural constructs. In South Africa, apartheid categories are still vivid, which affect spiritual, cultural and racial mental constructs and impact on the mental health of individuals across cultural groups. This article focuses on the long-term development of spiritual and cultural concepts within a selected individual in Cape Town, South Africa, during 11 years of field work. It also explores the impact of spirituality and culture on the researcher-researched relationship. A mixed-method approach was used, including various qualitative methods of data collection as well as content analysis to analyse the data and intersubjective validation to interpret them. Findings show a strong intrapersonal interlinkage of spirituality, culture and mental health and the researcher-researched relationship having a strong impact on spiritual, cultural and mental health constructions. We are not human beings having a spiritual experience. We are spiritual beings having a human experience. (Pierre Teilhard de Chardin, 1976).

Actual technologies are changing Cultural Heritage research, analysis, conservation and development ways, allowing new innovative approaches. The possibility of integrating Cultural Heritage data, like archaeological information, inside a three-dimensional environment system (like a Building Information Modelling) involve huge benefits for its management, monitoring and valorisation. Nowadays there are many commercial BIM solutions. However, these tools are thought and developed mostly for architecture design or technical installations. An example of better solution could be a dynamic and open platform that might consider Cultural Heritage needs as priority. Suitable solution for better and complete data usability and accessibility could be guaranteed by open source protocols. This choice would allow adapting software to Cultural Heritage needs and not the opposite, thus avoiding methodological stretches. This work will focus exactly on analysis and experimentations about specific characteristics of these kind of open source software (DBMS, CAD, Servers) applied to a Cultural Heritage example, in order to verifying their flexibility, reliability and then creating a dynamic HBIM open source prototype. Indeed, it might be a starting point for a future creation of a complete HBIM open source solution that we could adapt to others Cultural Heritage researches and analysis.

To understand Chinese immigrants' experiences with mental illness stigma and mental health disparities, we integrate frameworks of 'structural vulnerability' and 'moral experience' to identify how interaction between structural discrimination and cultural engagements might shape stigma. Fifty Chinese immigrants, including 64% Fuzhounese immigrants who experienced particularly harsh socio-economical deprivation, from two Chinese bilingual psychiatric inpatient units in New York City were interviewed from 2006 to 2010 about their experiences of mental illness stigma. Interview questions were derived from 4 stigma measures, covering various life domains. Participants were asked to elaborate their rating of measure items, and thus provided open-ended, narrative data. Analysis of the narrative data followed a deductive approach, guided by frameworks of structural discrimination and "what matters most" - a cultural mechanism signifying meaningful participation in the community. After identifying initial coding classifications, analysis focused on the interface between the two main concepts. Results indicated that experiences with mental illness stigma were contingent on the degree to which immigrants were able to participate in work to achieve "what mattered most" in their cultural context, i.e., accumulation of financial resources. Structural vulnerability - being situated in an inferior position when facing structural discrimination - made access to affordable mental health services challenging. As such, structural discrimination increased healthcare spending and interfered with financial accumulation, often resulting in future treatment nonadherence and enforcing mental health disparities. Study participants' internalizing their structurally-vulnerable position further led to a depreciated sense of self, resulting in a reduced capacity to advocate for healthcare system changes. Paradoxically, the multi-layered structural marginalization experienced by Chinese

Full Text Available Daphnia (water fleas belong to the zooplankton group called Cladocerans have sexual reproduction when conditions less favorable that produce diapausing eggs are enclosed in the ephippium. Hatching ephippial eggs in the laboratory is important in ecological, toxicology, genetical, and evolutionary studies. This study aims to improve the current methods of egg hatching from ephippium. Each of 50 ephippium were treated together by placing them in a glass jar and adding 50 mL bleach solution (sodium hypochlorite. Concentrations of sodium hypochlorite used in this experiment were 0%, 0.5%, 1%, 2%, 4% and 8%. These concentration treatments were crossed with the following exposure times (1, 2, 4, 8, 16, and 32 minutes. Culturing was done in 80 mL of artificial Daphnia medium, incubated in constant light and temperatures 20°C for 25 days. There were two repetitions in this experiment that were run at the same time. Result of this experiment showed that pretreatment with 0.5-8% bleach solution significantly increases the yield of total hatch rate of Daphnia magna resting eggs by about 21% over unbleached control. However, there was no significant difference among the bleach treatments. Concentration of bleach solution 0.5%, 1% and 4% significantly accelerated the time period until the first hatching (first day hatching. Difference of exposure time (1 - 32 minutes at each concentration treatments were not influence the yield of total hatch and the time period until first hatching.

2015-01-01

The experience of the Federal Budget Institution of the Scientific and Technical Center for Nuclear and Radiation Safety in the field of expertise of the safety rationales for nuclear power plants with WWER-type reactors of new projects is disclosed. In determining the priority, in addition to the necessary time and financial resources, it also took into account the extent to which these activities significantly affect the completeness of the implementation of levels of defense in depth related to the management of beyond-design-basis accidents, including severe ones. And also, what impact does this or that measure have on reducing the likelihood of the onset of severe radiation effects. When examining the safety justification for new design solutions (including for nuclear power plants with a reactor type WWER), it is advisable to adhere to the following approach: during the examination it is necessary to study the experience in the country and the world related to the proposed new design solutions; It is preferable to take advantage of the differential approach to assessing various aspects related to nuclear and radiation safety. The result of the examination of the justification for new design solutions may be recommendations on the development of existing regulatory documents or development of the Regulatory Authority [ru

A solution-grown stilbene detector was used in several experiments with plutonium samples including plutonium oxide, mixed oxide, and plutonium metal samples. Neutrons from different reactions and plutonium isotopes are accompanied by numerous gamma rays especially by the 59-keV gamma ray of {sup 241}Am. Identifying neutrons correctly is important for nuclear nonproliferation applications and makes neutron/gamma discrimination and pile-up rejection necessary. Each experimental dataset is presented with and without pile-up filtering using a previously developed algorithm. The experiments were simulated using MCNPX-PoliMi, a Monte Carlo code designed to accurately model scintillation detector response. Collision output from MCNPX-PoliMi was processed using the specialized MPPost post-processing code to convert neutron energy depositions event-by-event into light pulses. The model was compared to experimental data after pulse-shape discrimination identified waveforms as gamma ray or neutron interactions. We show that the use of the digital pile-up rejection algorithm allows for accurate neutron counting with stilbene to within 2% even when not using lead shielding.

Pragmatic prevention, permanent solution: Women's experiences with hysterectomy in rural India.

Science.gov (United States)

Desai, Sapna

2016-02-01

Hysterectomy appears to be on the rise amongst low-income, rural women in India as routine treatment for gynaecological ailments. This paper explores the individual, household, socio-economic and health system factors that influenced women's decisions to undergo hysterectomy in rural Gujarat, with a focus on women's perspectives. Interviews were conducted with 35 rural, low-income women who had undergone hysterectomy, local gynaecologists and other key informants, alongside observation of daily life and health-related activities. Inductive, open coding was conducted within a framework analysis to identify thematic influences on the decision to undergo hysterectomy. Women underwent hysterectomy at an average age of 36, as treatment for typically severe gynaecological ailments. I argue that women, faced with embedded social inequality in the form of gender biases, lack of labour security and a maternal-centric health system, demonstrated pragmatic agency in their decision to remove the uterus. When they experienced gynaecological ailments, most sought two to three opinions and negotiated financial and logistical concerns. The health system offered few non-invasive services for non-maternal health issues. Moreover, women and health care providers believed there is limited utility of the uterus beyond childbearing. Women's responsibilities as caretakers, workers and producers drove them to seek permanent solutions that would secure their long-term work and health security. Thus, hysterectomy emerged as a normalised treatment for gynaecological ailments, particularly for low-income women with limited resources or awareness of potential side effects. In this setting, hysterectomy reflects the power structures and social inequalities in which women negotiated medical treatment--and the need to reverse a culture of permanent solutions for low-income women.

ALECTO is a critical experiment intended for the neutronic study of homogeneous aqueous multiplying media. It essentially consists of a cylindrical tank, reflected or not, where can be made critical a solution of fissionable material fed into the tank from a geometrically subcritical storage. The studies effected on this assembly concern on one hand the determination of critical masses, on the other hand the nuclear parameters used in neutron calculations. The container tested in the first series of experiments hereby described is a cylindrical tank, 324 mm diameter with a convex bottom, water reflected on the sides and on the inferior part. The minimum critical mass of this tank was determined and was found to be: M cmin = 845 ± 7 g. The decay constant of prompt neutrons as a function of reactivity was determined by the pulsed neutron technique. At the critical state, it was found to be: α c = 73 ± 6 s -1 . Furthermore, from the study of this tank, were derived a number of safety regulations for plutonium solutions. (authors) [fr

A two dimensional clinostat experiment for microalgae cultures - basic work for bio- regenerativ life support systems

Harting, Benjamin; Slenzka, Klaus

2012-07-01

To investigate the influence of microgravity environments on photosynthetic organisms we designed a 2 dimensional clinostatexperiment for a suspended cell culture of Chlamydomonas reinhardtii. A novel approach of online measurments concerning relevant parameters important for the clasification of photosynthesis was obtained. To adress the photosynthesis rate we installed and validated an optical mesurement system to monitor the evolution and consumption of dissolved oxygen. Simultaneously a PAM sensor to analyse the flourescence quantum yield of the photochemical reaction was integarted. Thus it was possible to directly classify important parameters of the phototrophic metabolism during clinorotation. The experiment design including well suited light conditions and further biochemical analysis were directly performed for microalgal cell cultures. Changes in the photosynthetic efficiancy of phototrophic cyanobacteria has been observed during parabolic flight campaign but the cause is already not understood. Explenations could be the dependency of gravitaxis by intracellular ionconcentartion or the existance of mechanosensitive ionchannels for example associated in chloroplasts of Chlamydomonas reinhardtii. The purpuse of the microalgal clinostat are studies in a qasi microgravity environment for the process design of future bioregenerative life suport systems in spaceflight missions. First results has indicated the need for special nourishment of the cell culture during microgravity experiments. Further data will be presented during the assembly.

Micro-scale NMR Experiments for Monitoring the Optimization of Membrane Protein Solutions for Structural Biology.

Horst, Reto; Wüthrich, Kurt

2015-07-20

Reconstitution of integral membrane proteins (IMP) in aqueous solutions of detergent micelles has been extensively used in structural biology, using either X-ray crystallography or NMR in solution. Further progress could be achieved by establishing a rational basis for the selection of detergent and buffer conditions, since the stringent bottleneck that slows down the structural biology of IMPs is the preparation of diffracting crystals or concentrated solutions of stable isotope labeled IMPs. Here, we describe procedures to monitor the quality of aqueous solutions of [ 2 H, 15 N]-labeled IMPs reconstituted in detergent micelles. This approach has been developed for studies of β-barrel IMPs, where it was successfully applied for numerous NMR structure determinations, and it has also been adapted for use with α-helical IMPs, in particular GPCRs, in guiding crystallization trials and optimizing samples for NMR studies (Horst et al ., 2013). 2D [ 15 N, 1 H]-correlation maps are used as "fingerprints" to assess the foldedness of the IMP in solution. For promising samples, these "inexpensive" data are then supplemented with measurements of the translational and rotational diffusion coefficients, which give information on the shape and size of the IMP/detergent mixed micelles. Using microcoil equipment for these NMR experiments enables data collection with only micrograms of protein and detergent. This makes serial screens of variable solution conditions viable, enabling the optimization of parameters such as the detergent concentration, sample temperature, pH and the composition of the buffer.

The Experiment Dashboard system provides common solutions for monitoring job processing, data transfers and site/service usability. Over the last seven years, it proved to play a crucial role in the monitoring of the LHC computing activities, distributed sites and services. It has been one of the key elements during the commissioning of the distributed computing systems of the LHC experiments. The first years of data taking represented a serious test for Experiment Dashboard in terms of functionality, scalability and performance. And given that the usage of the Experiment Dashboard applications has been steadily increasing over time, it can be asserted that all the objectives were fully accomplished.

Enhancing Oceanography Classrooms with "Captive and Cultured" Ocean Experiences

Science.gov (United States)

Macko, S. A.; Tuite, M.; O'Connell, M.

2012-04-01

Students in oceanography classes often request more direct exposure to actual ocean situations or field trips. During regular session (13 week) or shorter term (4 week) summer classes such long trips are logistically difficult owing to large numbers of students involved or timing. This new approach to such a course supplement addresses the requests by utilizing local resources and short field trips for a limited number of students (20) to locations in which Ocean experiences are available, and are often supported through education and outreach components. The vision of the class was a mixture of classroom time, readings, along with paper and actual laboratories. In addition short day-long trips to locations where the ocean was "captured" were also used to supplement the experience as well as speakers involved with aquaculture ("cultivated") . Central Virginia is a fortunate location for such a class, with close access for "day travel" to the Chesapeake Bay and numerous field stations, museums with ocean-based exhibits (the Smithsonian and National Zoo) that address both extant and extinct Earth history, as well as national/state aquaria in Baltimore, Washington and Virginia Beach. Furthermore, visits to local seafood markets at local grocery stores, or larger city markets) enhance the exposure to productivity in the ocean, and viability of the fisheries sustainability. The course could then address not only the particulars of the marine science, but also aspects of ethics, including keeping animals in captivity or overfishing of particular species and the special difficulties that arise from captive or culturing ocean populations. In addition, the class was encouraged to post web-based journals of experiences in order to share opinions of observations in each of the settings.

The experiences of African American graduate students: A cultural transition

Science.gov (United States)

Joseph, Joretta

Historically Black Colleges and Universities (HBCU) have long been an intellectual resource for the African American community. HBCUs have provided and continue to provide an educational pathway for many Black students, particularly women who seek graduate and advanced degrees. However, despite the overwhelmingly positive presence of HBCU in the African American community, the academic training of students who graduate from HBCUs may be perceived as insufficient by predominantly White graduate institutions (PWIs). As a result, African American students who are not well integrated into their respective departmental communities and cultures at PW/is are likely to leave graduate school. Thus the continuing loss of talented people, potential research, role models for society, and the next generation of African American students in the fields of math, engineering, and the sciences (STEM) create a segregated and limited university environment. Studies in the field that attempt to provide insight in to experiences of underrepresented students are ultimately beneficial. However, often such studies do not address the process of adapting to the culture of a predominantly white institution (PWI), particularly within white and male dominated fields such as mathematics and the sciences. Research has also indicated that the first two years at a predominantly white graduate institution is the crucial transitional period for students of color, and it is this transitional moment in time that is the focus of this study. I consider how students make the transition from HBCU to majority institutions, and what impact this transition has on their persistence and commitment to their discipline. The limited amount of research that does address the experiences of minority doctoral students in math and science is usually coupled with the experiences of women. However, race and gender are not linear or additive. It cannot be assumed that the same factors that effect the under representation

Meaningful experiences in science education: Engaging the space researcher in a cultural transformation to greater science literacy

Science.gov (United States)

Morrow, Cherilynn A.

1993-01-01

The visceral appeal of space science and exploration is a very powerful emotional connection to a very large and diverse collection of people, most of whom have little or no perspective about what it means to do science and engineering. Therein lies the potential of space for a substantially enhanced positive impact on culture through education. This essay suggests that through engaging more of the space research and development community in enabling unique and 'meaningful educational experiences' for educators and students at the pre-collegiate levels, space science and exploration can amplify its positive feedback on society and act as an important medium for cultural transformation to greater science literacy. I discuss the impact of space achievements on people and define what is meant by a 'meaningful educational experience,' all of which points to the need for educators and students to be closer to the practice of real science. I offer descriptions of two nascent science education programs associated with NASA which have the needed characteristics for providing meaningful experiences that can cultivate greater science literacy. Expansion of these efforts and others like it will be needed to have the desired impact on culture, but I suggest that the potential for the needed resources is there in the scientific research communities. A society in which more people appreciate and understand science and science methods would be especially conducive to human progress in space and on Earth.

The repertoire of free-living protozoa in contact lens solutions is poorly known despite the fact that such protozoa may act as direct pathogens and may harbor intra-cellular pathogens. Between 2009 and 2014, the contact lens solutions collected from patients presenting at our Ophthalmology Department for clinically suspected keratitis, were cultured on non-nutrient agar examined by microscope for the presence of free-living protozoa. All protozoa were identified by 18S rRNA gene sequencing. A total of 20 of 233 (8.6 %) contact lens solution specimens collected from 16 patients were cultured. Acanthamoeba amoeba in 16 solutions (80 %) collected from 12 patients and Colpoda steini, Cercozoa sp., Protostelium sp. and a eukaryotic more closely related to Vermamoeba sp., were each isolated in one solution. Cercozoa sp., Colpoda sp., Protostelium sp. and Vermamoeba sp. are reported for the first time as contaminating contact lens solutions. The repertoire of protozoa in contact lens solutions is larger than previously known.

2018-02-01

To investigate the potential effects of the PKC/CREB pathway on the expressions of GABA A receptor subunits α1, γ2, and δ in cultured hippocampal neurons using a model of epilepsy that employed conditions of low magnesium (Mg 2+ ). A total of 108 embryonic rats at the age of 18 embryonic days (E18)prepared from adult female SD rats were used as experimental subjects. Primary rat hippocampal cultures were prepared from the embryonic 18 days rats. The cultured hippocampal neurons were then treated with artificial cerebrospinal fluid containing low Mg 2+ solutions to generate a low Mg 2+ model of epilepsy. The low Mg 2+ stimulation lasted for 3 h and then returned to in maintenance medium for 20 h. The changes of the GABA A receptor subunit α1, γ2, δ were observed by blocking or activating the function of the CREB. The quantification of the GABA A receptor subunit α1, γ2, δ and the CREB were determined by a qRT-PCR and a Western blot method. After the neurons were exposed to a low-Mg 2+ solution for 3 h, GABA A receptor mRNA expression markedly increased compared to the control, and then gradually decreased. In contrast, CREB mRNA levels exhibited a dramatic down-regulation 3 h after terminating low-Mg 2+ treatment, and then peaked at 9 h. Western blot analyses verified that staurosporine suppressed CREB phosphorylation (p-CREB). The mRNA expression of GABA A receptor subunit α1 increased only in the presence of staurosporine, whereas the expressions of subunits γ2 and δ significantly increased in the presence of either KG-501 or staurosporine. Furthermore, phorbol 12-myristate 13-acetate (PMA) decreased the expressions of GABA A subunits α1, γ2, and δ when administered alone. However, the administration of either KG-501 or staurosporine reversed the inhibitory effects of PMA. The PKC/CREB pathway may negatively regulate the expressions of GABA A receptor subunits α1, γ2, and δ in cultured hippocampal neurons in low Mg 2+ model of

In the present study, we evaluated the cytotoxicity of anti-allergic ophthalmic solutions in cultured corneal and conjunctival cells, namely SIRC (rabbit corneal epithelium), BCE C/D-1b (bovine corneal epithelial cells), RC-1 (rabbit corneal epithelium), and Chang (human conjunctival cells). The viability of cell cultures was determined following the exposure of cells to 12 commercially available anti-allergic ophthalmic solutions for varying exposure times and at various dilutions using the MTT and neutral red assays. The cell viability score (CVS) was used to compare the toxicity of different drugs. Based on CVS data, the order of cell viability after exposure to the drugs was Zepelin ≥ Tramelas PF ≥ Cumorol PF ≥ Ketotifen PF ≥ Eyevinal = Fumarton ≥ Cumorol > Intal ≥ Rizaben ≥ Tramelas ≥ Patanol Livostin. In conclusion, cell viability was mostly affected by the concentration of benzalkonium chloride rather than the active component and/or the anti-allergic action of the drug. The CVS was useful in comparing the toxicity of different drugs.

Although collaborative, culturally competent care has been shown to increase positive health outcomes and client satisfaction with services, little is known about the ways that clinicians implement service delivery models with immigrant families having a child with a disability. The purpose of this study is to examine the experiences of clinicians working with immigrant families raising a child with a physical disability and to examine the views and experiences of clinicians providing collaborative, culturally competent care to immigrant families raising a child with a physical disability. This study draws on in-depth interviews with 43 clinicians within two pediatric centers in Toronto and Quebec. Our findings show that clinicians remove or create barriers for immigrant families in different ways, which affect their ability to provide culturally competent care for immigrant families raising a child with a physical disability. Our findings suggest that there is a need for more institutional support for collaborative, culturally competent care to immigrant families raising a child with a physical disability. There is a lack of formal processes in place to develop collaborative treatment plans and approaches that would benefit immigrant families. Implications for Rehabilitation Clinicians need greater institutional support and resources to spend more time with families and to provide more rehabilitative care in families' homes. Building rapport with families includes listening to and respecting families' views and experiences. Facilitate collaboration and culturally competent care by having team meetings with parents to formulate treatment plans.

Full Text Available The article is devoted to the main problems and perspectives in modern culture and musical education in Russia on the threshold of the 20-21 st centuries, emphasizing visible contradictions and connection between them, ways of their solution and practical realization in the sphere of musical education. The content of education is constantly updated thanks to the cultural heritage of different countries and peoples; industries are constantly evolving science, as well as life and the practical experience of the person. Thorough theoretical analysis pointed out the necessity of structural and contents reconstruction in the work of institutions of musical education, both professional and non-professional. The focus should be on preserving the long-time cultivation and experience of Russian classic academic musical tradition, on the one hand. On the other hand, musical education in the present-day Russia should develop in accordance with the main trends of the social-cultural realities and cultural policy. Musical education is the inseparable part of general education, and institutions of musical education feel responsibility in training a new generation of teachers who can cope with the task of educating a new generation within the changing realities of the contemporary world.

Clini, P.; Nespeca, R.; Ruggeri, L.

2017-05-01

Today the ICTs are favourable additions to museum exhibitions. This work aims to realize an innovative system of digital exploitation of artefacts in the National Archaeological Museum of Marche (MANaM), in order to create a shared museum that will improve the knowledge of cultural contents through the paradigm "learning by interacting" and "edutainment". The main novelty is the implementation of stand-alone multimedia installations for digital artefacts that combine real and virtual scenarios in order to enrich the experience, the knowledge and the multi-sensory perception. A Digital Library (DL) is created using Close Range Photogrammetry (CRP) techniques applied to 21 archaeological artefacts belonging to different categories. Enriched with other data (texts, images, multimedia), all 3D models flow into the cloud data server from which are recalled in the individual exhibitions. In particular, we have chosen three types of technological solutions: VISUAL, TACTILE, SPATIAL. All the solutions take into account the possibility of group interaction, allowing the participation of the interaction to an appropriate number of users. Sharing the experience enables greater involvement, generating communicative effectiveness much higher than it would get from a lonely visit. From the "Museum Visitors Behaviour Analysis" we obtain a survey about users' needs and efficiency of the interactive solutions. The main result of this work is the educational impact in terms of increase in visitors, specially students, learning increase of historical and cultural content, greater user involvement during the visit to the museum.

2015-01-01

The efficiency of activated biochar fibres obtained from Opuntia ficus indica regarding the sorption of hexavalent uranium (U(VI)) from aqueous solutions has been investigated by batch experiments, as a function of various physicochemical parameters, and FTIR spectroscopy prior and after U(VI) sorption. The experimental results show that the activated biochar fibres possess extraordinary sorption capacity for U(VI) even in acidic solutions (q max = 210 g kg -1 ), which is attributed to the formation of inner-sphere complexes with the surface carboxylic moieties, available in high density on the lamellar structures of the bio-sorbent. The adsorption process is described by a two-step exothermic reaction. (author)

Leisure Traveling for 21st Century Americans: Mass Tourism as a Cultural Trap

Directory of Open Access Journals (Sweden)

Aniculăese Ovidiu

2014-01-01

Full Text Available The majority of mass men in the American environment exhibit predictable and similar patterns of behavior as tourists. Pre-Industrial Revolution modes of traveling as liberation and exploration are now thwarted by the leveling effect of globalization and the illusion of information fueled by the all-pervasive mass media. Claims about the role of routine or the quest for authenticity are challenged as genuine motivations for mass tourism. Both the American culture and travel destinations in developing countries have authentic content that is largely ignored in favor of sensationalism and cliché. Excessive regimentation in the US creates the acute need for transcending to which popular culture finds accessible solutions through tourism: an experience of concentrated yet vague exoticism which feels liberating without yielding exploration. Travel destinations are shaped to American standards of material comfort and even adopt western popular culture icons in an effort to supply accessible familiar experiences of western entertainment. Various kinds of difficulty that once stimulated travelers are now relieved by travel agencies, rendering the experience of traveling less personal and more like TV entertainment. Old notions of space, time and reality itself are blurred in favor of a hyper-reality where fiction dominates.

In order to create a culture more open to novel problem-solving mechanisms, NASA's Human Health and Performance Directorate (HH&P) created a strategic knowledge management tool that educates employees about innovative problem-solving techniques, the Solution Mechanism Guide (SMG). The SMG is a web-based, interactive guide that leverages existing and innovative problem-solving methods and presents this information as a unique user experience so that the employee is empowered to make the best decision about which problem-solving tool best meets their needs. By integrating new and innovative methods with existing problem solving tools, the SMG seamlessly introduces open innovation and collaboration concepts within HH&P to more effectively address human health and performance risks. This commentary reviews the path of creating a more open and innovative culture within HH&P and the process and development steps that were taken to develop the SMG.

Full Text Available An experiment was conducted to identify the hydroponic culture based suitable media for the production of Zucchini Squash in the Biochemistry Laboratory, Patuakhali Science and Technology University, Dumki, Patuakhali, Bangladesh during 2014. Zucchini plant (Cucurbita pepo L. were grown in closed soilless systems to determine the effect of four different hydroponics media on plant growth, yield and nutrient contents (fruit moisture content, ascorbic acid content on fruit, fruit protein content, protein content in leaves. Three types of substrates (coconut husk, jute, cotton along with Hoagland solution were used in this experiment. Result revealed that media using Jute fiber showed significant effect on plant growth and nutritional values than the other media (media of cotton with Hoagland solution, coconut husk with Hoagland solution and only Hoagland solution. The plant grown using jute media showed the highest plant height (60.33 cm, number of leaves (17.33, yield (1.5 kg plant-1, fruit moisture content (97.33%, Ascorbic acid content in fruit (28.73 mg 100g-1, protein percentage in fruit (1.406% and percentage (1.326% in leaves than the other media. Therefore, with the controlled nutrient supply, less expense, less labor, no use of pesticides or fertilizer with controlled environment the use of jute fiber as a substrate with Hoagland solution can be an effective one.

Infants prefer the musical meter of their own culture: a cross-cultural comparison.

Soley, Gaye; Hannon, Erin E

2010-01-01

Infants prefer native structures such as familiar faces and languages. Music is a universal human activity containing structures that vary cross-culturally. For example, Western music has temporally regular metric structures, whereas music of the Balkans (e.g., Bulgaria, Macedonia, Turkey) can have both regular and irregular structures. We presented 4- to 8-month-old American and Turkish infants with contrasting melodies to determine whether cultural background would influence their preferences for musical meter. In Experiment 1, American infants preferred Western over Balkan meter, whereas Turkish infants, who were familiar with both Western and Balkan meters, exhibited no preference. Experiments 2 and 3 presented infants with either a Western or Balkan meter paired with an arbitrary rhythm with complex ratios not common to any musical culture. Both Turkish and American infants preferred Western and Balkan meter to an arbitrary meter. Infants' musical preferences appear to be driven by culture-specific experience and a culture-general preference for simplicity. Copyright 2009 APA, all rights reserved.

Previous research on the reading abilities of Deaf individuals from various cultural groups suggests that Black Deaf and Hispanic Deaf individuals lag behind their White Deaf peers. The present study compared the reading skills of Black Deaf and White Deaf individuals, investigating the influence of American Sign Language (ASL), culture, family characteristics, reading experience, and education. (The descriptor Black is used throughout the present article, as Black Deaf individuals prefer this term to African American. For purposes of parallel construction, the term White is used instead of European American.) It was found that Black Deaf study participants scored lower on measures of both reading and ASL. These findings provide implications for possible interventions at the primary, secondary, and college levels of education.

2002-01-01

The second series of critical experiments with 10% enriched uranyl nitrate solution using 28-cm-thick slab core have been performed with the Static Experiment Critical Facility of the Japan Atomic Energy Research Institute. Systematic critical data were obtained by changing the uranium concentration of the fuel solution from 464 to 300 gU/l under various reflector conditions. In this paper, the thirteen critical configurations for water-reflected cores and unreflected cores are identified and evaluated. The effects of uncertainties in the experimental data on k eff are quantified by sensitivity studies. Benchmark model specifications that are necessary to construct a calculational model are given. The uncertainties of k eff 's included in the benchmark model specifications are approximately 0.1%Δk eff . The thirteen critical configurations are judged to be acceptable benchmark data. Using the benchmark model specifications, sample calculation results are provided with several sets of standard codes and cross section data. (author)

Bhatti, S.A.N.; Arshad, N.

2016-01-01

The prevalence of a good safety culture is equally important for all kind of organizations involved in nuclear business including operating organizations, designers, regulator, etc., and this should be reflected through all the processes and activities of these organizations. The need for inculcating safety culture into regulatory processes and practices is gradually increasing since the major accident at Fukushima. Accordingly, several international fora in last few years repeatedly highlighted the importance of prevalence of safety culture in regulatory bodies as well. The utilisation of concept of safety culture always remained applicable in regulatory activities of PNRA in the form of core values. After the Fukushima accident, PNRA considered it important to check the extent of utilisation of safety culture concept in organizational activities and decided to conduct its “Safety Culture Self-Assessment (SCSA)” for presenting itself as a role model in-order to endorse the fact that safety culture at regulatory authority plays an important role to influence safety culture at licenced facilities.

Avatar in the Amazon - Narratives of Cultural Conversion and Environmental Salvation between Cultural Theory and Popular Culture

Directory of Open Access Journals (Sweden)

John Ødemark

2015-10-01

Full Text Available In 2010 the New York Times reported that '[t]ribes of Amazon Find an Ally Out of "Avatar"', James Cameron. The alliance was against the building of Belo Monte, a hydroelectricdam in the Xingu River in Brazil. Cameron made a documentary about Belo Monte, A Message from Pandora. Here he states that Avatar becomes real in the struggle against the dam. This appears to confirm U. K. Heise's observation that the 'Amazon rainforest has long functioned as a complex symbol of exotic natural abundance, global ecological connectedness, and environmental crisis'. This construal, however, downplays the 'symbols' cultural components. In this article I show that the image of an ecological 'rainforest Indian' and a particular kind of culture constitutes a crucial part of the Amazon as 'a complex' cross-disciplinary 'symbol'. Firstly, I examine how an Amazonian topology (closeness to nature, natural cultures is both a product of an interdisciplinary history, and a place to speak from for ethno-political activist. Next I analyze how Amazonian cultures have been turned into 'ethnological isolates' representing a set of grand theoretical problems in anthropology, not least concerning the nature/culture-distinction, and how environmentalism has deployed the same topology. Finally I examine how Avatar and one of its cinematic intertexts, John Boorman's The Emerald Forest, is used as a model to understand the struggle over the Belo Monte. In a paradoxical way the symbolic power of indigenous people in ecological matters here appears to be dependent upon a non-relation, and a reestablishment of clear cut cultural boundaries, where 'the tribal' is also associated with the human past. Disturbingly such symbolic exportation of solutions is consonant with current exportations of the solution of ecological problems to 'other places'.

Research towards a plasma exhaust solution for a fusion power plant aims at validating edge physics models, strengthening predictive capabilities and improving the divertor configuration. The TCV tokamak is extensively used to investigate the extent that geometric configuration modifications can affect plasma exhaust performance. Recent TCV experiments continue previous detachment studies of Ohmically heated L-mode plasmas in standard single-null configurations, benefitting from a range of improved diagnostic capabilities. Studies were extended to nitrogen seeding and an entire suite of alternative magnetic configurations, including flux flaring towards the target (X divertor), increasing the outer target radius (Super-X) and movement of a secondary x-point inside the vessel (X-point target) as well as the entire range of snowflake configurations. Nitrogen seeding into a snowflake minus configuration demonstrated a regime with strong radiation in the large region between the two x-points, confirming EMC3-Eirene simulations, and opening a promising path towards highly radiating regimes with limited adverse effects on core performance.

Transport and reaction kinetics at the glass:solution interface region: results of repository-oriented leaching experiments

1987-01-01

Repository-oriented leaching experiments involving Savannah River Laboratory (SRL) 165 type glass under a γ-radiation field (1 +/- 0.2 x 10 4 R/h) have been performed by the Nevada Nuclear Waste Storage Investigations (NNWSI) project. In this communication, they discuss glass surface analyses obtained by SEM, nuclear resonance profiling, and SIMS together with leachate solution data in relation to a mechanism that couples diffusion, hydrolysis (etching and gelation), and precipitation to qualitatively describe the release of different glass components to the leachant solutions. The release of mobile (e.g., Li) and partly mobile (e.g., B) species is controlled primarily by interdiffusion with water species across the interdiffusion zone. Glass components that are immobile in the interdiffusion zone are released to the solution by etching. For prediction of long-term steady-state concentrations of glass components with low solubility, the relative rates of release from the glass and secondary mineral precipitation must be taken into account. 20 references, 5 figures, 1 table

A safety culture is the collective effort of an institution to direct its resources toward the goal of safety. An analysis is performed on the six years of experience of the Committee on the Safety of Neonatal Patient. A mailbox was created for the declaration of adverse events, and measures for their correction were devised, such as case studies, continuous education, prevention of nosocomial infections, as well as information on the work done and its assessment. A total of 1287 reports of adverse events were received during the six years, of which 600 (50.8%) occurred in the neonatal ICU, with 15 (1.2%) contributing to death, and 1282 (99.6%) considered preventable. Simple corrective measures (notification, security alerts, etc.) were applied in 559 (43.4%), intermediate measures (protocols, monthly newsletter, etc.) in 692 (53.8%), and more complex measures (causal analysis, scripts, continuous education seminars, prospective studies, etc.) in 66 (5.1%). As regards nosocomial infections, the prevention strategies implemented (hand washing, insertion and maintenance of catheters) directly affected their improvement. Two surveys were conducted to determine the level of satisfaction with the Committee on the Safety of Neonatal Patient. A rating 7.5/10 was obtained in the local survey, while using the Spanish version of the Hospital Survey on Patient Safety Culture the rate was 7.26/10. A path to a culture of safety has been successfully started and carried out. Reporting the adverse events is the key to obtaining information on their nature, etiology and evolution, and to undertake possible prevention strategies.

A process development for the elimination of mercury and nitrates from the HEWC (high-enriched waste concentrates) solutions has been achieved. This process is based on the reduction of mercury to metal with formaldehyde. The pilot plant which has enabled to test the developed process is described as well as the experiments. The residual mercury concentration is of 25 mg/1 but the mechanism of the reduction is not yet known. During the denitration the nitrous vapors production calls for an oversized absorption column. The control instruments and the analytical methods are also described. (AF)β

Synthesis and properties of ternary (K, NH4, H3O)-jarosites precipitated from Acidithiobacillus ferrooxidans cultures in simulated bioleaching solutions

International Nuclear Information System (INIS)

Sandy Jones, F.; Bigham, Jerry M.; Gramp, Jonathan P.; Tuovinen, Olli H.

2014-01-01

The purpose of this study was to synthesize a series of solid solution jarosites by biological oxidation of ferrous iron at pH 2.2–4.4 and ambient temperature in media containing mixtures of K + (0, 1, 4, 6, 12, 31 mM) and NH 4 + (6.1, 80, 160, 320 mM). The starting material was a liquid medium for Acidithiobacillus ferrooxidans comprised of 120 mM FeSO 4 solution and mineral salts at pH 2.2. Following inoculation with A. ferrooxidans, the cultures were incubated in shake flasks at 22 °C. As bacteria oxidized ferrous iron, ferric iron hydrolyzed and precipitated as jarosite-group minerals (AFe 3 (SO 4 ) 2 (OH) 6 ) and/or schwertmannite (idealized formula Fe 8 O 8 (OH) 6 (SO 4 )·nH 2 O). The precipitates were characterized by X-ray diffraction (XRD), elemental analysis, and Munsell color. Schwertmannite was the dominant mineral product at low combinations of K + (≤ 4 mM) and NH 4 + (≤ 80 mM) in the media. At higher single or combined concentrations, yellowish jarosite phases were produced, and Munsell hue provided a sensitive means of detecting minor schwertmannite in the oxidation products. Although the hydrated ionic radii of K + and NH 4 + are similar, K + greatly facilitated the formation of a jarosite phase compared to NH 4 + . Unit cell and cell volume calculations from refinements of the powder XRD patterns indicated that the jarosite phases produced were mostly ternary (K, NH 4 , H 3 O)-solid solutions that were also deficient in structural Fe, especially at low NH 4 contents. Thus, ferric iron precipitation from the simulated bioleaching systems yielded solid solutions of jarosite with chemical compositions that were dependent on the relative concentrations of K + and NH 4 + in the synthesis media. No phase separations involving discrete, end-member K-jarosite or NH 4 -jarosite were detected in the un-aged precipitates. - Highlights: • Fe(III) precipitates formed in A. ferrooxidans culture solutions were characterized. • The monovalent cation

Research highlights: → The FEBEX experiment is a 1:1 simulation of a high level waste disposal facility in crystalline rock according to the Spanish radwaste disposal concept. → Solute transfer processes occurrs at the bentonite-granite interface. → An increase of Cl and Na is observed in granitic water of the surrounding of the experiment. → Solute transfer does not affect the sealing and thermo-hydromechanical properties of the engineered barriers. → A diffusive transport of Cl and Na simulated by 1D transport modeling with an effective diffusion coefficient of D e ≅ 5.0 E-11 m 2 /s. - Abstract: The FEBEX experiment is a 1:1 simulation of a high level waste disposal facility in crystalline rock according to the Spanish radwaste disposal concept. This experiment has been performed in a gallery drilled in the underground laboratory Grimsel Test Site (Switzerland). Two boreholes parallel to the FEBEX drift were drilled 20 and 60 cm away from the granite-bentonite interface to provide data on potential bentonite-granite solutes transfer. Periodic sampling and analysis of the major ions showed: (a) the existence of solutes transfer from the bentonite porewater towards the granite groundwater, explaining the Cl - and Na + contents of the latter; (b) that the concentration of the natural tracers coming into the granite groundwater from the bentonite porewater increased over time. This bentonite-granite solutes transfer was modelled in order to predict the increase in the Cl - and Na + concentrations of the granite groundwater. The modelled results seem to confirm that the mechanism of solute migration in this scenario is that of diffusive transport. An effective diffusion coefficient of D e = 5 x 10 -11 m 2 /s was that which best fitted the data obtained.

Culture and biology interplay: An introduction.

Causadias, José M; Telzer, Eva H; Lee, Richard M

2017-01-01

Culture and biology have evolved together, influence each other, and concurrently shape behavior, affect, cognition, and development. This special section highlights 2 major domains of the interplay between culture and biology. The first domain is neurobiology of cultural experiences-how cultural, ethnic, and racial experiences influence limbic systems and neuroendocrine functioning-and the second domain is cultural neuroscience-the connections between cultural processes and brain functioning. We include 3 studies on neurobiology of cultural experiences that examine the associations between racial discrimination and heart rate variability (Hill et al., 2016), economic and sociocultural stressors and cortisol levels (Mendoza, Dmitrieva, Perreira, & Watamura, 2016), and unfair treatment and allostatic load (Ong, Williams, Nwizu, & Gruenewald, 2016). We also include 2 studies on cultural neuroscience that investigate cultural group differences and similarities in beliefs, practices, and neural basis of emotion regulation (Qu & Telzer, 2016), and reflected and direct self-appraisals (Pfeifer et al., 2016). We discuss pending challenges and future directions for this emerging field. (PsycINFO Database Record (c) 2017 APA, all rights reserved).

Prediction of thermodynamic properties of solute elements in Si solutions using first-principles calculations

International Nuclear Information System (INIS)

Iwata, K.; Matsumiya, T.; Sawada, H.; Kawakami, K.

2003-01-01

The method is presented to predict the activity coefficients and the interaction parameters of the solute elements in infinite dilute Si solutions by the use of first-principles calculations based on density functional theory. In this method, the regular solution model is assumed. The calculated activity coefficients in solid Si are converted to those in molten Si by the use of the solid-liquid partition coefficients. Furthermore, the interaction parameters in solid Si solutions are calculated and compared with reported experimental values of those in liquid Si solutions. The results show that the calculated activity coefficients and interaction parameters of Al, Fe, Ti and Pb in Si solutions are in good agreement with the tendency of the experiments. However, the calculations have some quantitative discrepancy from the experiments. It is expected that consideration of the excess entropy would reduce this discrepancy

Digital culture as a converging paradigm for technology and culture: Challenges for the culture sector

Directory of Open Access Journals (Sweden)

Aleksandra Uzelac

2010-05-01

Full Text Available Digital culture is a new and complex concept. Digital advances are increasingly interacting with the world of culture and the arts, leading to a convergence of technologies, media and information and shaping communication modes. The new possibilities offered by the digital technologies -namely, global connectivity and the emergence of new networks- challenge our traditional understanding of culture and make it necessary for us to take on the board the concept of a digital culture. This article views digital culture as a new social system that determines experiences and opportunities for the citizens of today. Digital technologies and the networked environment have introduced new practices, opportunities and threats, and the culture sector needs to find appropriate ways for operating in this new reality.

The in vitro culture behaviour of embryonic stem cells (ESC) is strongly influenced by the culture conditions. Current culture media for expansion of ESC contain some undefined substances. Considering potential clinical translation work with such cells, the use of defined media is desirable. We have used Design of Experiments (DoE) methods to investigate the composition of a serum-free chemically defined culture medium for expansion of mouse embryonic stem cells (mESC). Factor screening analysis according to Plackett-Burman revealed that insulin and leukaemia inhibitory factor (LIF) had a significant positive influence on the proliferation activity of the cells, while zinc and L: -cysteine reduced the cell growth. Further analysis using minimum run resolution IV (MinRes IV) design indicates that following factor adjustment LIF becomes the main factor for the survival and proliferation of mESC. In conclusion, DoE screening assays are applicable to develop and to refine culture media for stem cells and could also be employed to optimize culture media for human embryonic stem cells (hESC).

Reconceptualizing Cultural Globalization: Connecting the “Cultural Global” and the “Cultural Local”

Directory of Open Access Journals (Sweden)

Stephen Magu

Full Text Available Scholars generally are in agreement that the pace of globalization is rapidly accelerating. Globalization’s impact, beyond the socio-economic and political discourses, is affecting conceptions of culture and cultural studies, and changing and restructuring spaces, global, national and personal interactions and relationships. The “texts” and artifacts borne of culture—activities, events and our conception thereof are a mechanism for the propagation of culture. Simultaneously Westernization/Americanization impacts local cultures through consumerism, which obfuscates local traditions, knowledge and experiences. This research argues that culture is a dynamic, adaptive concept and practice, “borrowing” liberally from ideological and technological innovations of other cultures and integrating these borrowed aspects into the construction and modification of culture across spatial and geographical divides to ensure particular cultures’ survival. The research shows that the local affects the global, and vice versa. It selects local communication “texts” to show that cultures are not “victims” of globalization or the proliferation of mass media. Cultures actively adopt and integrate globalization’s technological artifacts. Globalization’s positive effects are dynamic and span cultural interactions and permeate structures of authority at personal, national and global levels.

The cultural construction of emotions

Mesquita, B.; Boiger, M.; De Leersnyder, J.

A large body of anthropological and psychological research on emotions has yielded significant evidence that emotional experience is culturally constructed: people more commonly experience those emotions that help them to be a good and typical person in their culture. Moreover, experiencing these

Transport of solutes helps to regulate normal physiology and proper function of cartilage in diarthrodial joints. Multiple studies have shown the effects of characteristic parameters such as concentration of proteoglycans and collagens and the orientation of collagen fibrils on the diffusion process. However, not much quantitative information and accurate models are available to help understand how the characteristics of the fluid surrounding articular cartilage influence the diffusion process. In this study, we used a combination of micro-computed tomography experiments and biphasic-solute finite element models to study the effects of three parameters of the overlying bath on the diffusion of neutral solutes across cartilage zones. Those parameters include bath size, degree of stirring of the bath, and the size and concentration of the stagnant layer that forms at the interface of cartilage and bath. Parametric studies determined the minimum of the finite bath size for which the diffusion behavior reduces to that of an infinite bath. Stirring of the bath proved to remarkably influence neutral solute transport across cartilage zones. The well-stirred condition was achieved only when the ratio of the diffusivity of bath to that of cartilage was greater than ≈1000. While the thickness of the stagnant layer at the cartilage-bath interface did not significantly influence the diffusion behavior, increase in its concentration substantially elevated solute concentration in cartilage. Sufficient stirring attenuated the effects of the stagnant layer. Our findings could be used for efficient design of experimental protocols aimed at understanding the transport of molecules across articular cartilage. Copyright © 2016 Elsevier Ltd.

Full Text Available Culture plays an important role on human lives and it has been in four ancient civilizations of China, Iran, Egypt and Greece. The civilization achievements are normally categorized in two different groups of material and immaterial. Practical experience of the material, social objective is called as a civilization and the mental aspect of spiritual experiences, spiritual and personal is called culture. The purpose of this research is to find a framework for cross-cultural management. First, we define the cultural planning and we review the existing cultural examples in Iranian society and try to provide an overall analysis. The paper also investigates the role of government on creating adaptive culture within the society and explains that government must act as leadership in creating value added culture.

The transmission and stability of cultural life scripts: a cross-cultural study.

Science.gov (United States)

Janssen, Steve M J; Haque, Shamsul

2018-01-01

Cultural life scripts are shared knowledge about the timing of important life events. In the present study, we examined whether cultural life scripts are transmitted through traditions and whether there are additional ways through which they can be attained by asking Australian and Malaysian participants which information sources they had used to generate the life script of their culture. Participants hardly reported that they had used cultural and religious traditions. They more often reported that they had used their own experiences and experiences of relatives and friends. They also reported the use of comments of relatives and friends and the use of newspapers, books, movies and television programmes. Furthermore, we examined the stability of life scripts and similarities and differences across cultures. We found that life scripts are stable cognitive structures and that there are, besides cross-cultural differences in the content, small cross-cultural differences in the valence and distribution of life script events, with the Australian life script containing more positive events and more events expected to occur before the age of 16.

Full Text Available The internationalization of higher education has been dramatically intensified over the last fifteen years in Brazil, creating wide-ranging opportunities as well as threats and limitations in relation to foreign language teaching practices and the teaching of culture. Many linguists and anthropologists (BYRAM, 1997; KRAMSCH, 1993; MCKAY, 2003; JENKINS, 2005 have stated that for communication to be successful the use of language must be associated with other culturally appropriated behavior, not just linguistic rules in the strict sense. In this article, we discuss the problems related to internationalization, more specifically, the discussion revolves around the sociocultural challenges faced by some students of the Federal Institute of Piauí (IFPI regarding their experiences in the Science without Borders program spread through five countries. By using qualitative interviews, the results revealed that students had sociocultural problems which could be avoided if English teachers had worked in the language classroom before the execution of the exchange program.

The movement of solutes through aqueous fissures in micro-porous rock during borehole experiments

International Nuclear Information System (INIS)

Glueckauf, E.

1981-02-01

When a tracer is injected for a short period into a solution flowing through a fissure in micro-porous rock, that tracer is not only carried along by the aqueous stream, but its local concentration is also markedly affected by hydro-dynamic dispersion and by sideway diffusion and adsorption in the micro-porous rock. The process has been simulated by computer calculations and these have made it possible to obtain from the concentration-time curves observed in borehole experiments an assessment of the physical parameters involving the water velocity and the hydro-dynamic dispersion in the fissure, and the diffusion and adsorption in the micro-porous rock. With these parameters it was then possible to recalculate quantitatively the local concentration-time history. However, in actual borehole experiments, the velocity of the water stream in the fissure is not known, and numerous side effects can distort the shape of the observed tracer curves. In order to test the theoretical interpretation more thoroughly, it is therefore proposed to carry out a laboratory experiment which simulates the borehole test under strictly defined conditions.

Full Text Available This is a discussion paper which aims to contribute to the systematization of studies, concepts and practices on cultural policies which have been developed in previous years in Brazil and are orienting cultural actions and public programs in the country, also influencing the Occupational Therapy. Citizenship and Cultural Diversity are concepts under construction and are part of the of the agenda of cultural policies and as well as the reflections and practices of various occupational therapists who are acting in a constant dialogue with the cultural area by means of the formation in cultural management, cultural mapping, programs and grant projects aimed to promote inventive identities, traditional communities, native populations, urban mobility, and cultural networks and exchange initiatives, among others. The article presents the process of this conceptual construction and the constitution of experiences aiming the democratization of the culture in the history of Brazilian cultural public policies, over which are being discussed approach paths and possibilities for Occupational Therapy.

Wutich, A.; White, A. C.; White, D. D.; Larson, K. L.; Brewis, A.; Roberts, C.

2014-01-01

In this study, we examine how development status and water scarcity shape people's perceptions of "hard path" and "soft path" water solutions. Based on ethnographic research conducted in four semi-rural/peri-urban sites (in Bolivia, Fiji, New Zealand, and the US), we use content analysis to conduct statistical and thematic comparisons of interview data. Our results indicate clear differences associated with development status and, to a lesser extent, water scarcity. People in the two less developed sites were more likely to suggest hard path solutions, less likely to suggest soft path solutions, and more likely to see no path to solutions than people in the more developed sites. Thematically, people in the two less developed sites envisioned solutions that involve small-scale water infrastructure and decentralized, community-based solutions, while people in the more developed sites envisioned solutions that involve large-scale infrastructure and centralized, regulatory water solutions. People in the two water-scarce sites were less likely to suggest soft path solutions and more likely to see no path to solutions (but no more likely to suggest hard path solutions) than people in the water-rich sites. Thematically, people in the two water-rich sites seemed to perceive a wider array of unrealized potential soft path solutions than those in the water-scarce sites. On balance, our findings are encouraging in that they indicate that people are receptive to soft path solutions in a range of sites, even those with limited financial or water resources. Our research points to the need for more studies that investigate the social feasibility of soft path water solutions, particularly in sites with significant financial and natural resource constraints.

Production de minitubercules de pomme de terre par hydroponie: évaluation d'un système combinant les techniques NFT et Gravel Culture pour deux types de solutions nutritives

Full Text Available Potato minituber production through hydropony: assessment of a system combining the NFT and Gravel Culture techniques for two types of nutrient solutions. The potato minituber production is the classical intermediate stage enabling field use of potato materials with an in vitro origin. This production of minitubers may be achieved through various techniques. Most often however they are based upon bedding vitroplantlets or vitroplantlets cuttings in an organic substratum which is disinfected or not. The soilless culture of plants stemming from vitrotubers to produce minitubers with a superior health quality was tested within a hydroponic system. Two types of nutrient solutions were compared: a nitrogen rich one (NPK, mg/l, 180-40-300 and a phosphorus rich one (NPK, mg/l, 60-150-300. In order to initiate the cultures, presprouting microtubers of several varieties (Bintje, Kennebec, Spunta, Saturna, Desiree and Gasore were used. Multiplication rates ranged between 13.2 (Saturna and 3.8 (Kennebec minitubers with a grade higher than 10 mm (more than 1.5 g. As the selected density of the plants was 59 plants per square metre, the yield per square metre varied from 224 to 779 minitubers with a grade higher than 10 mm. The obtained number of minitubers depended especially on the variety. The phosphorus enrichment of the nutrient solution induced an increased number of minitubers produced with a grade higher than 15 mm (more than 5 g. The health state of the produced tubers was excellent.

The results of experiments performed in recent years on board facilities such as the Space Shuttle/Spacelab have demonstrated that many cell systems, ranging from simple bacteria to mammalian cells, are sensitive to the microgravity environment, suggesting gravity affects fundamental cellular processes. However, performing well-controlled experiments aboard spacecraft offers unique challenges to the cell biologist. Although systems such as the European 'Biorack' provide generic experiment facilities including an incubator, on-board 1-g reference centrifuge, and contained area for manipulations, the experimenter must still establish a system for performing cell culture experiments that is compatible with the constraints of spaceflight. Two different cell culture kits developed by the French Space Agency, CNES, were recently used to perform a series of experiments during four flights of the 'Biorack' facility aboard the Space Shuttle. The first unit, Generic Cell Activation Kit 1 (GCAK-1), contains six separate culture units per cassette, each consisting of a culture chamber, activator chamber, filtration system (permitting separation of cells from supernatant in-flight), injection port, and supernatant collection chamber. The second unit (GCAK-2) also contains six separate culture units, including a culture, activator, and fixation chambers. Both hardware units permit relatively complex cell culture manipulations without extensive use of spacecraft resources (crew time, volume, mass, power), or the need for excessive safety measures. Possible operations include stimulation of cultures with activators, separation of cells from supernatant, fixation/lysis, manipulation of radiolabelled reagents, and medium exchange. Investigations performed aboard the Space Shuttle in six different experiments used Jurkat, purified T-cells or U937 cells, the results of which are reported separately. We report here the behaviour of Jurkat and U937 cells in the GCAK hardware in ground

The Rhetoric and Reality of Leading the Inclusive School: Socio-Cultural Reflections on Lived Experiences

Lindy-Anne Abawi

2018-04-01

Full Text Available This paper details a cross-cultural study of inclusive leadership practices within a basic education context in each of the following countries: Australia, Canada, and Colombia. Each school was selected after district educational leaders identified the school as being inclusive of students with diverse learning needs over an extended period of time. The researchers were particularly interested in the norms and assumptions that were evident within conversations because these were viewed as indicators of the nature of the embedded school culture within each context. School leaders and teachers were interviewed to determine the link between rhetoric and reality, and what inclusion ‘looked like’, ‘felt like’, and ‘sounded like’ at each site, and whether any discernible differences could be attributed to societal culture. A refractive phenomenological case study approach was used to capture the messages within each context and the lived experiences of the participants as they sought to cater for the needs of students. Data were collected from semi-structured interviews with school leaders and teaching staff. Each researcher conducted environmental observations, documenting the impressions and insights gained from the more implicit messages communicated verbally, non-verbally, and experientially from school structures, visuals, and school ground interactions. Themes were collated from the various narratives that were recounted. Both similarities and distinct socio-cultural differences emerged.

CHALLENGES IN CROSS CULTURAL ADVERTISING

Directory of Open Access Journals (Sweden)

Yuni Retnowati

2016-04-01

Full Text Available At first, marketing practitioners and academics consider standardized approaches to marketing and advertising strategies in globalization, and then some studies proved that the standardization of advertising across culture is not valid. Therefore, cross cultural advertising takes local culture into account when conveying messages in advertisements. Cross cultural understanding is very important in order to produce successful localized advertising that would reflect the cultural values and norms of intended audience. Challenge in cross cultural advertising is the problem of communicating to people of diverse cultural background. Cross cultural solutions are applied in areas such as language, communication style, images and cultural values. Cross cultural advertising is simply about using common sense and analyzing how the different elements of an advertising campaign are impacted by culture and modifying them to best speak to the target audience. Other challenges are determining between standardization and adaptation of cultural values content of advertising when facing different people from diverse cultures. In academic side, the challenge is preparing students to design advertisements that communicate effectively to diverse cultures.

Solution preparation

Seitz, M.G.

1982-01-01

Reviewed in this statement are methods of preparing solutions to be used in laboratory experiments to examine technical issues related to the safe disposal of nuclear waste from power generation. Each approach currently used to prepare solutions has advantages and any one approach may be preferred over the others in particular situations, depending upon the goals of the experimental program. These advantages are highlighted herein for three approaches to solution preparation that are currently used most in studies of nuclear waste disposal. Discussion of the disadvantages of each approach is presented to help a user select a preparation method for his particular studies. Also presented in this statement are general observations regarding solution preparation. These observations are used as examples of the types of concerns that need to be addressed regarding solution preparation. As shown by these examples, prior to experimentation or chemical analyses, laboratory techniques based on scientific knowledge of solutions can be applied to solutions, often resulting in great improvement in the usefulness of results

A framework for the organizational assumptions underlying safety culture

International Nuclear Information System (INIS)

Packer, Charles

2002-01-01

The safety culture of the nuclear organization can be addressed at the three levels of culture proposed by Edgar Schein. The industry literature provides a great deal of insight at the artefact and espoused value levels, although as yet it remains somewhat disorganized. There is, however, an overall lack of understanding of the assumption level of safety culture. This paper describes a possible framework for conceptualizing the assumption level, suggesting that safety culture is grounded in unconscious beliefs about the nature of the safety problem, its solution and how to organize to achieve the solution. Using this framework, the organization can begin to uncover the assumptions at play in its normal operation, decisions and events and, if necessary, engage in a process to shift them towards assumptions more supportive of a strong safety culture.

Experiments with a First Prototype of a Spatial Model of Cultural Meaning through Natural-Language Human-Robot Interaction

Oliver Schürer

2018-01-01

Full Text Available When using assistive systems, the consideration of individual and cultural meaning is crucial for the utility and acceptance of technology. Orientation, communication and interaction are rooted in perception and therefore always happen in material space. We understand that a major problem lies in the difference between human and technical perception of space. Cultural policies are based on meanings including their spatial situation and their rich relationships. Therefore, we have developed an approach where the different perception systems share a hybrid spatial model that is generated by artificial intelligence—a joint effort by humans and assistive systems. The aim of our project is to create a spatial model of cultural meaning based on interaction between humans and robots. We define the role of humanoid robots as becoming our companions. This calls for technical systems to include still inconceivable human and cultural agendas for the perception of space. In two experiments, we tested a first prototype of the communication module that allows a humanoid to learn cultural meanings through a machine learning system. Interaction is achieved by non-verbal and natural-language communication between humanoids and test persons. This helps us to better understand how a spatial model of cultural meaning can be developed.

2018-02-01

The current research offers an alternative to essentialism for studying cultural variation in emotional experience. Rather than assuming that individuals always experience an emotion in the same way, our starting point was that the experience of an emotion like anger or shame may vary from one instance to another. We expected to find different anger and shame experience types, that is, groups of people who differ in the instances of anger and shame that they experience. We proposed that studying cultural differences in emotional experience means studying differences in the distribution of these types across cultural contexts: There should be systematic differences in the types that are most common in each culture. Students from the United States, Japan, and Belgium (N = 928) indicated their emotional experiences in terms of appraisals and action tendencies in response to 15 hypothetical anger or shame situations. Using an inductive clustering approach, we identified anger and shame types who were characterized by different patterns of anger and shame experience. As expected, we found that the distribution of these types differed across the three cultural contexts: Of the two anger types, one was common in Japan and one in the United States and Belgium; the three shame types were each most prevalent in a different cultural context. Participants' anger and shame types were primarily predicted by their culture of origin (with an accuracy of 72.3% for anger and 74.0% for shame) and not, or much less, by their ethnic origin, socioeconomic status, gender, self-construal, or personality.

Hayslip, Bert; Toledo, Ray M; Henderson, Craig E; Rodriguez, R Mishelle; Caballero Vela, Daniela M

2018-01-01

This study examined grandchildren's perceptions of the quality of their relationship with their grandmothers and how these perceptions relate to psychosocial outcomes. Eighty-two youth from Mexico and 99 youth from the United States aged between 13 and 16 participated. Results suggested that both cultures benefit in unique ways from positive relationship with their grandmothers. Yet, there were also differences in the relational experience of grandmother-grandchild relationships across cultures. Specifically, grandchildren in the U.S. sample reported higher relationship quality, relational competency, and self-efficacy than the grandchildren in the Mexico sample. Within the U.S. sample, relationship quality was associated with grandchildren's relational competence, while in the Mexico sample, relationship quality was associated with self-efficacy. Limitations of the present study include restricted generalizability to other age groups and to grandfathers and that only one element of the grandparent-grandchild dyad was sampled. Longitudinal research will improve our understanding of the causal dynamics of grandparent-grandchild relationships.

CANCER PATIENT’S EXPERIENCE CROSSING THE HEALTH CULTURE

2014-12-01

Full Text Available Cognitive anthropology does not predict human behavior, but tries to access principles that rule behavior. Cross-cultural communication is a skill acquired through a learning process, and it can improve doctor-patient relationship and enhance the outcomes of care. The unfulfilled expectations of a patient may influence the patient self-esteem and his perceived role in the society. For some patients living with cancer, it was found as an unforeseen benefit of learning to be closer to God. Based on a narrative communication, we tried to underline cross-cultural differences in cancer patients from different countries with various backgrounds. We described the patient reactions, his way of interpreting the things that happened to him, and his actions regarding adaptive changes in behavior. The originality of the study resides in understanding cross-cultural patterns of cancer patients. The innovative element is the use of qualitative research and its application in health care.

Music, culture and identity

Full Text Available At the time of globalization it is difficult to pretend avoiding music culture and identity from political, cultural and social developments. Thus, it is impossible for the music to be unshakable and to represent national identity by not taking and giving nothing to culture. The dynamics of life and the rapid development of technology make it impossible for the culture to remain unaffected in terms of sharing experiences social experiences. Culture represents our current course, both in terms of politics, also in the social and human aspects. Through the technology it is possible for our children to be equal with children of all other countries, to exchange information and to connect directly with all countries of the world. Musical education is one of the main factors of cultural development and preservation of national identity. Identity consists of everything we posses and reflect. We are those who distinguish from each other and have a common denominator compared to other nations.

Background. Increasing awareness in the last decade concerning environmental quality had prompted research into 'green solutions' for soil and water remediation, progressing from laboratory in vitro experiments to pot and field trials. In vitro cell culture experiments provide a convenient system to study basic biological processes, by which biochemical pathways, enzymatic activity and metabolites can be specifically studied. However, it is difficult to relate cell cultures, calli or even hydroponic experiments to the whole plant response to pollutant stress. In the field, plants are exposed to additional a-biotic and biotic factors, which complicate further plant response. Hence, we often see that in vitro selected species perform poorly under soil and field conditions. Soil physical and chemical properties, plant-mycorrhizal association and soil-microbial activity affect the process of contaminant degradation by plants and/or microorganisms, pointing to the importance of pot and field experiments. Objective. This paper is a joint effort of a group of scientists in COST action 837. It represents experimental work and an overview on plant response to environmental stress from in vitro tissue culture to whole plant experiments in soil. Results. Results obtained from in vitro plant tissue cultures and whole plant hydroponic experiments indicate the phytoremediation potential of different plant species and the biochemical mechanisms involved in plant tolerance. In pot experiments, several selected desert plant species, which accumulated heavy metal in hydroponic systems, succeeded in accumulating the heavy metal in soil conditions as well.

In vitro plant tissue cultures provide a useful experimental system for the study of the mechanisms involved in the detoxification of organic and heavy metal pollutants.

In 2010, The Korea Electric Power Corporation (KEPCO) was awarded a multi-billion dollar bid to construct the first nuclear power plant in Barakah, UAE. One must keep in mind however, that with technology transfer and international cooperation comes a host of potential problems arising from cultural differences such as language, everyday habitudes and workplace expectation. As of now, how problematic these potential issues may become is unknown. Of the aforementioned factors, communication is perhaps of foremost importance. We investigated UAE culture-related issues through analysis of operating experience reviews (OERs) and came to the conclusion that the language barrier needed utmost attention. Korean nuclear power plant operators will work in UAE and will operate the NPPs with operators and managers of other nationalities as well. The purpose of this paper is firstly to confirm that operators are put under mental stress, and secondly to demonstrate the decline in accuracy when they must work in English. Reducing human error is quite important to make nuclear power plants safer. As the mental workload of human operator is increased, the probability of a human error occurring also increases. It will have a negative influence on the plant’s safety. There are many factors which can potentially increase mental workload. We focused on communication problem which is a key factor of increasing mental workload because many Korean operators will work in UAE nuclear power plants and may work together with UAE operators. From these experiments we compared how performance of both Korean and UAE subjects were decreased when they use English. We designed experimental methods to be able to check this problem qualitatively and quantitatively. We analyzed four factors to find the communication problems from the experiments which are accuracy, efficiency, NASA-TLX, and brain wave. Accuracy, efficiency, brain wave are quantitative factors, and NASA-TLX is qualitative factor. To

Culture Wires the Brain: A Cognitive Neuroscience Perspective.

There is clear evidence that sustained experiences may affect both brain structure and function. Thus, it is quite reasonable to posit that sustained exposure to a set of cultural experiences and behavioral practices will affect neural structure and function. The burgeoning field of cultural psychology has often demonstrated the subtle differences in the way individuals process information-differences that appear to be a product of cultural experiences. We review evidence that the collectivistic and individualistic biases of East Asian and Western cultures, respectively, affect neural structure and function. We conclude that there is limited evidence that cultural experiences affect brain structure and considerably more evidence that neural function is affected by culture, particularly activations in ventral visual cortex-areas associated with perceptual processing. © The Author(s) 2010.

This study explored the following issues related to pain management among nursing home (NH) residents: 1) communication patterns between NH residents and certified nursing assistants (CNAs) about pain; 2) how race and ethnicity influence NH residents' pain experiences; and 3) CNAs' personal experiences with pain that may affect their empathy toward the resident's pain experience. The study consisted of a convenience sample of four focus groups (n = 28) from a NH in central Florida. A content analysis approach was used. Data were analyzed with the use of Atlas.ti version 6.2. The content analysis identified four main themes: 1) attitudes as barriers to communication about resident pain care; 2) cultural, religious, and gender influences of resident pain care by CNAs; 3) the role of empathy in CNAs care of residents with pain; and 4) worker strategies to detect pain. Attitudes among CNAs about resident cognitive status and perceived resident burden need to be recognized as barriers to the detection and reporting of pain by CNAs and should be addressed. In addition, NHs should consider a person-centered approach to pain that is culturally competent given the cultural influences of both residents and staff. Finally, educational programs for CNAs that include empathy-inducing scenarios could potentially improve the care provided by CNAs when dealing with residents' pain.

Solution microcalorimeter for measuring heats of solution of radioactive elements and compounds

International Nuclear Information System (INIS)

Raschella, D.L.

1978-12-01

The microcalorimeter vessel is constructed of tantalum metal, with a nominal volume of 5 cm 3 . Its energy equivalent is 24 J K -1 when containing 5 cm 3 H 2 O. The thermal leakage modulus is 0.010 min -1 . A thermistor is employed as the temperature sensor. The operating sensitivity is about 1 x 10 -5 K (300 μJ). The performance of the calorimetry system was tested using tris(hydroxymethyl)aminomethane (TRIS) and magnesium metal. The results of the TRIS experiments, at a concentration of 1 g dm -3 in 0.1 N HCl at 298 K, yielded a heat of solution of -29.606 +- 0.063 kJ mol -1 . The magnesium experiments, in 1 N HCl at 298 K, gave a heat of solution of -465.965 +- 1.136 kJ mol -1 . The heat of solution of curium-248 metal in 1 N HCl at 298 K was measured. The experiments, which should not be considered definitive, yielded a heat of solution of -606.4 +- 1.8 kJ mol -1 . A single measurement in 6 N HCl gave a heat of solution of -602.3 kJ mol -1 . From these results the heat of formation of Cm 3+ /sub (aq)/ is calculated to be -607.2 +- 2.5 kJ mol -1

Park, Mijung; Chesla, Catherine A; Rehm, Roberta S; Chun, Kevin M

2011-11-01

The aim of this study is to describe how mental healthcare providers adapted their practice to meet the unique needs of Asian Americans. As the number of ethnic minorities and multicultural patients and families rapidly increases, cultural competency becomes an essential skill for all healthcare providers. The lack of knowledge about how healthcare providers grapple with diverse cultures and cultural competency limits the ability of others to deliver patient-centred care across cultural lines. Interpretive phenomenology guided the design and conduct of this study. Twenty mental healthcare providers who treated Asian Americans were recruited. Narrative data were collected through face-to-face, in-depth interviews between 2006 and 2007. Three characteristics of culturally appropriate care for Asian Americans were identified. Cultural brokering: providers addressed issues stemming from cultural differences via bicultural skills education. Asian American patients generally received broader education than current literature recommended. Supporting families in transition: providers assisted Asian American families during transition from and to professional care. Using cultural knowledge to enhance competent care: providers' knowledge of Asian culture and flexible attitudes affected the care that they provided. Culturally competent providers were able to identify cultural issues that were relevant to the specific situation, and incorporated cultural solutions into the care provided. Culturally appropriate care is nuanced and context specific. Thus, more sophisticated and broader conceptualizations are necessary to prepare nurses for such complex practice. © 2011 Blackwell Publishing Ltd.

2014-03-01

The ageing and frail migrants who are at the end of life are an increasing share of migrants living in Australia. However, within such populations, information about end-of-life experiences is limited, particularly among Africans. This article provides some insights into the sociocultural end-of-life experiences of Africans in Australia and their interaction with the health services in general and end-of-life care in particular. It provides points for discussion to consider an ethical framework that include Afro-communitarian ethical principles to enhance the capacity of current health services to provide culturally appropriate and ethical care. This article contributes to our knowledge regarding the provision of culturally appropriate and ethical care to African patients and their families by enabling the learning of health service providers to improve the competence of palliative care systems and professionals in Australia. Additionally, it initiates the discussion to highlight the importance of paying sufficient attention to a diverse range of factors including the migration history when providing palliative and hospice care for patients from African migrant populations.

Cooperation, decision time, and culture: Online experiments with American and Indian participants.

Full Text Available Two separate bodies of work have examined whether culture affects cooperation in economic games and whether cooperative or non-cooperative decisions occur more quickly. Here, we connect this work by exploring the relationship between decision time and cooperation in American versus Indian subjects. We use a series of dynamic social network experiments in which subjects play a repeated public goods game: 80 sessions for a total of 1,462 subjects (1,059 from the United States, 337 from India, and 66 from other countries making 13,560 decisions. In the first round, where subjects do not know if connecting neighbors are cooperative, American subjects are highly cooperative and decide faster when cooperating than when defecting, whereas a majority of Indian subjects defect and Indians decide faster when defecting than when cooperating. Almost the same is true in later rounds where neighbors were previously cooperative (a cooperative environment except decision time among Indian subjects. However, when connecting neighbors were previously not cooperative (a non-cooperative environment, a large majority of both American and Indian subjects defect, and defection is faster than cooperation among both sets of subjects. Our results imply the cultural background of subjects in their real life affects the speed of cooperation decision-making differentially in online social environments.

After determining a need for organizational change informed by changes in workforce demographics, community demographics, the socio-political and economic environment, and constraints on resources, one agency sought to transform its organizational culture into that of a learning organization. An external organizational development consultant was hired to work with agency leadership to identify ways that would help move the agency's culture towards one that was conducive to learning. Specifically, the agency director sought to create a culture where communication is encouraged both vertically and horizontally, frontline level workers are engaged and their voices heard, cross-departmental problem solving is practiced, innovative ideas are supported, and evidence-informed practice regularly implemented. This case study describes the experiences of this agency and the process taken toward engaging an external consultant and moving towards the development of a culture of learning.

Discussions were given on a sterilizing effect of ozone on Fusarium bacteria in hydroponic culture, and its effect on components in the culture solution. In an experiment, dry air with O3 concentration of 3.5 ppm was sent into aqueous solution inoculated with Fusarium bacteria at a flow rate of 5 liters per minute. The Fusarium bacteria was sterilized nearly completely in about five minutes. No change was observed in pH, EC and dissolved oxygen concentration of the O3-treated culture solution. However, iron and manganese among the soluble components have been oxidized by O3 and precipitated, hence these components must be added after the O3 treatment. In spinach culture performed on a culture medium inoculated with Fusarium bacteria, ozone water containing dissolved O3 at 0.8 ppm was flown into a urethane foam medium and vegetable roots. This treatment has resulted in reduction of the number of strains occurred with a wilt symptom below that in the section flown with distilled water. The spinach has grown normally without showing an effect of the ozone water. 15 refs., 10 figs., 3 tabs.

This is a databook of TRACY ''ramp feed'' experiments. TRACY is a reactor to perform supercritical experiments using low-enriched uranyl nitrate aqueous solution. The excess reactivity of TRACY is 3$ at maximum, and it is inserted by feeding the solution to a core tank or by withdrawing a control rod, which is called as the transient rod, from the core. In the ramp feed experiment, the supercritical experiment is initiated by feeding the fuel solution to the core tank in a constant feed rate. The data in the present databook consist of datasheets and graphs. Experimental conditions and typical values of measured parameters are tabulated in the datasheet. In the graph, power and temperature profiles are plotted. Those data are useful for the investigation of criticality accidents with fissile solutions, and for validation of criticality accident analysis codes. (author)

Moving Into Communities: Developing Cultural Competence with Pre-service Educators through Community Service-Learning Experiences

Directory of Open Access Journals (Sweden)

Heather Coffey

2012-04-01

Full Text Available Research in teacher education suggests that field experiences in community settings can offer pre-service teachers a context for understanding the link between theory and practice. This paper documents the experiences of pre-service educators who participated in service-learning partnerships for thirty hours in multiple community settings in the southeast United States. Pre-service teachers not only volunteered in the community, but they also engaged in critically reflective journal writing and participated in evaluative class discussions. Students praised the benefits of a service experience in both school and community placements and discussed how interactions with the community agencies gave them the insight into how community organizations often play a significant role in the lives of the underserved students they will eventually teach. The author argues that the inclusion of a service-learning component in early pre-service teacher education field experiences has the potential to facilitate the examination of the relationships between community organizations and schools and encourage development of cultural competence among pre-service teachers. KEYWORDSservice-learning, pre-service teacher preparation, community partnerships

Karavaeva, E.N.; Molchanova, I.V.

1976-01-01

The results of experiments performed to study the behaviour of radioactive and stable isotopes of Ca in soil - solution - plant system at different soil moistening are given. The experiments have been conducted in culture pans with two soils: soddy-meadow and soddy-podzolic differing in a number of physico-chemical properties. The solution of radioactive Ca( 45 CaCl 2 ) has been applied to soddy-meadow soil at the rate of 0.2 μcurie/kg, and to soddy-podzolic soil - at the rate of 0.1 μcurie/kg. The distribution and accumulation coefficients are estimated by the ratio to the total content of stable Ca and 45 Ca in soil. A direct relationship between distribution coefficients and the rate of soil moistening is observed. It has been established that 45 Ca and the natural stable isotopes of Ca applied to the soil differ in the type of distribution in soil - soil solution system and in accumulation by plants. However, a great similarity has been observed in behaviour of radioactive and stable isotopes of Ca depending on soil moistening

Effect of Different Culture Media on Broccoli (Brassica oleracea var. italica Yield Components and Mineral Elements Concentration in Soilless Culture

Full Text Available Introduction: Broccoli is one of the valuable vegetables among brassicas which has received great attention throughout the world and is cultivated both in soil and soilless culture. Currently, we face restriction in high quality of the soils and water resources as two essential inputs in agriculture. Like other parts of the world, Iran is losing hundred hectares of its arable and fertile land annually due to salinity, alkalinity and waterlogging. One of the important strategies to overcome these adverse conditions is soilless culture systems. Among the different methods of soilless culture, substrate culture is more common and cheaper than others. Different kinds of organic and inorganic substances are used in soilless culture system, but the optimum mixture of growing medium is still a challenging issue. Physical and chemical characteristics of growing media can potentially affect the yield and product quality in direct and indirect ways. A good medium for soilless culture should have easy drainage, appropriate aeration, high water holding capacity and low price, as well as no weed seeds and pathogens. Therefore, this research was aimed to evaluate different prevalent growing media in broccoli soilless culture system. Materials and Methods: This experiment was conducted as an outdoor soilless culture system in outdoor hydroponic site in Sari Agricultural Sciences and Natural Recourses University (SANRU. To begin with, broccoli seeds were sown in transplanting tray, and after five weeks, the developed transplants were cultivated in growing bags in a soilless system. In this work, different mixtures of culture media were evaluated for yield component and mineral elements of broccoli. Ten kinds of different media comprising of cocopeat, perlite, sand, sawdust, sand+sawdust, sand+vermicompost, cocopeat+perlite, cocopeat+LECA, cocopeat+ pumice, and cocopeat+perlite+ vermicompost were compared in completely randomized design with tree replications

Full Text Available This article is an attempt to offer a conceptual understanding of various kinds of mega-events and to determine their significance as an instrument of the official international cultural policy. The article examines scientific approaches to understanding and classification of mega-events. The case studies focus on such mega-events as international cross-cultural years and cultural forums. The fact that the official foreign policy of¬ten defines and shapes the goals of mega-events proves their value in establishing and promoting a positive international image of the country. Recent Russian experience in organizing cross-cultural years is examined to discuss positive and negative socio-cultural impact.

Arcoleo, Kimberly; Zayas, Luis E; Hawthorne, April; Begay, Rachelle

2015-09-01

Patients' cultural health beliefs and behaviors may conflict with biomedical healthcare values and practices potentially leading to non-adherence with asthma treatment regimens. To optimize shared decision-making, healthcare providers should understand and be sensitive to these cultural beliefs and behaviors and negotiate an asthma management plan acceptable to parents. The purpose of this study was to obtain the perspective of Mexican mothers regarding (1) their experiences of living with a child with asthma, (2) their understanding of the nature of asthma, and (3) how their cultural beliefs influence asthma management. A qualitative, phenomenological study design was employed to assess mothers' lived experiences with and perceptions of their child's asthma. Individual in-depth interviews were conducted with a purposeful sample of 20 Mexican mothers of children ages 5-17 years with asthma. An inductive, theory-driven, phenomenological analysis approach was used to elicit thematic findings. Mothers expressed a symptomatic perception of asthma and limited understanding of the disease. Most believe the disease is present only when their child is symptomatic. Many are surprised and puzzled by the unpredictability of their child's asthma attacks, which they report as sometimes "silent". The inconsistency of triggers also leads to frustration and worry, which may reflect their concerns around daily controller medication use and preference for alternative illness management strategies. Our clinical encounters should be refocused to better understand the context of these families' lives and the cultural lens through which they view their child's asthma.

Culture's building blocks: investigating cultural evolution in a LEGO construction task.

McGraw, John J; Wallot, Sebastian; Mitkidis, Panagiotis; Roepstorff, Andreas

2014-01-01

ONE OF THE MOST ESSENTIAL BUT THEORETICALLY VEXING ISSUES REGARDING THE NOTION OF CULTURE IS THAT OF CULTURAL EVOLUTION AND TRANSMISSION: how a group's accumulated solutions to invariant challenges develop and persevere over time. But at the moment, the notion of applying evolutionary theory to culture remains little more than a suggestive trope. Whereas the modern synthesis of evolutionary theory has provided an encompassing scientific framework for the selection and transmission of biological adaptations, a convincing theory of cultural evolution has yet to emerge. One of the greatest challenges for theorists is identifying the appropriate time scales and units of analysis in order to reduce the intractably large and complex phenomenon of "culture" into its component "building blocks." In this paper, we present a model for scientifically investigating cultural processes by analyzing the ways people develop conventions in a series of LEGO construction tasks. The data revealed a surprising pattern in the selection of building bricks as well as features of car design across consecutive building sessions. Our findings support a novel methodology for studying the development and transmission of culture through the microcosm of interactive LEGO design and assembly.

Prevention of demoralization in prolonged bicultural conflict and interaction: the role of cultural receptors I - description of a natural experiment.

Science.gov (United States)

de Figueiredo, John M

2013-08-01

This article examines how symbols and sentiments are exchanged to produce a synthesis of two cultures in the context of prolonged bicultural conflict and interaction, thereby minimizing or preventing sociocultural disintegration and the resulting demoralization. This process will be shown to be anchored on the discovery of certain thematic areas (cultural receptors) in which social roles or cultural mandates are missing, unclear, ambiguous or congruent. The setting of this research is the history of Goa, a former Portuguese state on the western coast of India, where the exchange between the Portuguese and Indian cultures lasted longer than four centuries (1510-1961). Both published and unpublished sources were studied. From 1510, the year of the beginning of the Portuguese rule, until 1540, the local traditions and leadership patterns were respected. This was followed by a period of religious intolerance during which attempts were made to encourage Hindus to convert to Christianity and to wipe out the bicultural interaction. Finally a new era of tolerance and cultural integration started around 1773 and continued until 1961. The bicultural interaction persisted and a hybrid culture developed around cultural receptors. The history of Portuguese Goa is a natural experiment that allows us to examine the role played by cultural receptors in the adaptation to acculturative stress.

Increased adsorption of histidine-tagged proteins onto tissue culture polystyrene.

Holmberg, Maria; Hansen, Thomas Steen; Lind, Johan Ulrik; Hjortø, Gertrud Malene

2012-04-01

In this study we compare histidine-tagged and native proteins with regards to adsorption properties. We observe significantly increased adsorption of proteins with an incorporated polyhistidine amino acid motif (HIS-tag) onto tissue culture polystyrene (TCPS) compared to similar proteins without a HIS-tag. The effect is not observed on polystyrene (PS). Adsorption experiments have been performed at physiological pH (7.4) and the effect was only observed for the investigated proteins that have pI values below or around 7.4. Competitive adsorption experiments with imidazole and ethylenediaminetetraacetic acid (EDTA), as well as adsorption performed at different pH and ionic strength indicates that the high adsorption is caused by electrostatic interaction between negatively charged carboxylate groups on the TCPS surface and positively charged histidine residues in the proteins. Pre-adsorption of bovine serum albumin (BSA) does not decrease the adsorption of HIS-tagged proteins onto TCPS. Our findings identify a potential problem in using HIS-tagged signalling molecule in assays with cells cultured on TCPS, since the concentration of the molecule in solution might be affected and this could critically influence the assay outcome.

Li, Ming; Liu, Hong; Tong, Ling; Fu, Yuming; He, Wenting; Hu, Enzhu; Hu, Dawei

The Integrative Experimental System (IES) was established as a tool to evaluate the rela-tionship of the subsystems in Bioregenerative Life Support System, and Multibiological Life Support System Experiments (MLSSE) have been conducted in the IES. The IES consists of a higher plant chamber, an animal chamber and a plate photo bioreactor (PPB) which cultivated lettuce (Lactuca sativa L.), silkworm (Bombyx Mori L.) and microalgae (Chlorella vulgaris), respectively. In MLSSE, four volunteers took turns breathing the system air through a tube connected with the animal chamber periodically. According to the CO2 concentration in the IES, the automotive control system of the PPB changed the light intensity regulating the photosynthesis of Chlorella vulgaris to make CO2 /O2 in the system maintain at stable levels. Chlorella vulgaris grew with human urine by carrying certain amount of alga liquid out of the bioreactor every day with synthetic urine replenished into the system, and O2 was regenerated, at the same time human urine was purified. Results showed that this IES worked stably and Chlorella vulgaris grew well; The culture of Chlorella vulgaris could be used to keep the balance of CO2 and O2 , and the change of light intensity could control the gas composition in the IES; Microalgae culture could be used in emergency in the system, the culture of Chlorella vulgaris could recover to original state in 5 days; 15.6 ml of condensation water was obtained every day by the culture of Chlorella vulgaris; The removal efficiencies of N, P in human urine could reach to 98.2% and 99.5%.

Adsorption and translocation characteristics of radionuclides in the root of tomato plant were investigated. Mature tomato plant was transplanted to culture solution containing 85 Sr, 137 Cs, 131 I, 54 Mn, 60 Co and 65 Zn. Immediately after transplantation, the tomato plant was cut at 10 cm above the surface of the culture solution in order to collect bleeding sap solution (Experiment-1). Another mature tomato plant was cultured for 3 days in culture solution containing radionuclides as mentioned above and then transplanted to fresh culture solution. Bleeding sap solution was also collected in the same way as shown in Experiment-1 (Experiment-2). Activity ratios of bleeding sap to culture solution were measured for several hours. Adsorption and removement of those radionuclides in tomato plant were summarized as follows; 137 Cs was taken up by the root almost at the same speed as that of water and accumulated in the lowest among the six nuclides used in the experiments. The concentrations of 85 Sr, 54 Mn and 65 Zn in the bleeding sap of 3 days' uptake experiment were higher than the initial concentrations of the culture solution for several hours even after the tomato plant was transplanted to fresh culture solution. 131 I and 60 Co were accumulated much in the root and found extremely low in the bleeding sap during the experiment, suggesting that the nuclide were absorbed on the surface of the roots and scarcely moved.

2001-01-01

During the last decade, the need to promote and achieve high safety culture levels has been one of the priorities in the nuclear sector around the world, although it has been focused basically on nuclear power. Nevertheless, it is an important and current topic for any risk related activity, since it results in a greater involvement and commitment of managers and personnel to safety, thereby reducing the so called 'organizational failures', one of the most frequent contributors to several of the major industrial disasters in the recent years. The International Atomic Energy Agency (IAEA) has also pointed that out and in some of its recent publications and meetings has recognized the need for extending this concept to the area of radioactive source. In Cuba, the Regulatory Body has been working in this direction during several years, promoting national research and studies in this field, issuing documents and organizing events and other activities. With this it is expected to introduce new work methods and practices to be applied by management and personnel involved in the use of radioactive sources, reflecting a higher safety culture level. This paper summarizes the experience of Cuban Regulatory Body in this field. (author)

Cultural Psychiatry: A Spotlight on the Experience of Clinical Social Workers' Encounter with Jewish Ultra-Orthodox Mental Health Clients.

2017-07-01

Community is a complex issue, especially in two particular populations overlap: Haredi society, which embraces cultural codes common to closed communities, and the mental health population characterized by its own unique needs. The present study explores the encounter experience of social workers with the cultural perceptions of mental health clients in the Haredi community in light of Community Cultural Psychiatry. A qualitative-phenomenological approach was adopted. In-depth semi-structured interviews were conducted with 27 social workers, mental health professionals, who are in contact with ultra-Orthodox Jewish clients. Three major themes emerged from the data analysis: (1) Exclusion vs. grace and compassion. (2) Mental health: A professional or cultural arena? (3) Mental health help-seeking changing processes. This study shows that the attitude in the Haredi community toward mental health therapy undergoes a process of change. It is important to strengthen this process, together with preserving existing community informal structures of help.

Logging experiments with the laboratory-information management system ISPyB (Information System for Protein crystallography Beamlines) enhances the automation of small-angle X-ray scattering of biological macromolecules in solution (BioSAXS) experiments. The ISPyB interface provides immediate user-oriented online feedback and enables data cross-checking and downstream analysis. To optimize data quality and completeness, ISPyBB (ISPyB for BioSAXS) makes it simple for users to compare the results from new measurements with previous acquisitions from the same day or earlier experiments in order to maximize the ability to collect all data required in a single synchrotron visit. The graphical user interface (GUI) of ISPyBB has been designed to guide users in the preparation of an experiment. The input of sample information and the ability to outline the experimental aims in advance provides feedback on the number of measurements required, calculation of expected sample volumes and time needed to collect the data: all of this information aids the users to better prepare for their trip to the synchrotron. A prototype version of the ISPyBB database is now available at the European Synchrotron Radiation Facility (ESRF) beamline BM29 and is already greatly appreciated by academic users and industrial clients. It will soon be available at the PETRA III beamline P12 and the Diamond Light Source beamlines I22 and B21.

Hook, Joshua N; Davis, Don E; Owen, Jesse; Worthington, Everett L; Utsey, Shawn O

2013-07-01

Building on recent theory stressing multicultural orientation, as well as the development of virtues and dispositions associated with multicultural values, we introduce the construct of cultural humility, defined as having an interpersonal stance that is other-oriented rather than self-focused, characterized by respect and lack of superiority toward an individual's cultural background and experience. In 4 studies, we provide evidence for the estimated reliability and construct validity of a client-rated measure of a therapist's cultural humility, and we demonstrate that client perceptions of their therapist's cultural humility are positively associated with developing a strong working alliance. Furthermore, client perceptions of their therapist's cultural humility were positively associated with improvement in therapy, and this relationship was mediated by a strong working alliance. We consider implications for research, practice, and training. PsycINFO Database Record (c) 2013 APA, all rights reserved.

Culture Three Ways: Culture and Subcultures Within Countries.

Science.gov (United States)

Oyserman, Daphna

2017-01-03

Culture can be thought of as a set of everyday practices and a core theme-individualism, collectivism, or honor-as well as the capacity to understand each of these themes. In one's own culture, it is easy to fail to see that a cultural lens exists and instead to think that there is no lens at all, only reality. Hence, studying culture requires stepping out of it. There are two main methods to do so: The first involves using between-group comparisons to highlight differences and the second involves using experimental methods to test the consequences of disruption to implicit cultural frames. These methods highlight three ways that culture organizes experience: (a) It shields reflexive processing by making everyday life feel predictable, (b) it scaffolds which cognitive procedure (connect, separate, or order) will be the default in ambiguous situations, and (c) it facilitates situation-specific accessibility of alternate cognitive procedures. Modern societal social-demographic trends reduce predictability and increase collectivism and honor-based go-to cognitive procedures.

Quantitative and qualitative research across cultures and languages: cultural metrics and their application.

Science.gov (United States)

Wagner, Wolfgang; Hansen, Karolina; Kronberger, Nicole

2014-12-01

Growing globalisation of the world draws attention to cultural differences between people from different countries or from different cultures within the countries. Notwithstanding the diversity of people's worldviews, current cross-cultural research still faces the challenge of how to avoid ethnocentrism; comparing Western-driven phenomena with like variables across countries without checking their conceptual equivalence clearly is highly problematic. In the present article we argue that simple comparison of measurements (in the quantitative domain) or of semantic interpretations (in the qualitative domain) across cultures easily leads to inadequate results. Questionnaire items or text produced in interviews or via open-ended questions have culturally laden meanings and cannot be mapped onto the same semantic metric. We call the culture-specific space and relationship between variables or meanings a 'cultural metric', that is a set of notions that are inter-related and that mutually specify each other's meaning. We illustrate the problems and their possible solutions with examples from quantitative and qualitative research. The suggested methods allow to respect the semantic space of notions in cultures and language groups and the resulting similarities or differences between cultures can be better understood and interpreted.

Cross-cultural similarities and differences in the experience of awe.

Razavi, Pooya; Zhang, Jia Wei; Hekiert, Daniela; Yoo, Seung Hee; Howell, Ryan T

2016-12-01

Current research on awe is limited to Western cultures. Thus, whether the measurement, frequency, and consequences of awe will replicate across non-Western cultures remains unanswered. To address this gap, we validated the dispositional awe scale (Shiota, Keltner, & John, 2006) in 4 countries (United States, Iran, Malaysia, and Poland; N = 1,173) with extensive variations in cultural values (i.e., power distance) and personality profiles (i.e., extraversion and openness). Multigroup factor analyses demonstrated that, across all cultures, a 3-factor model that treats awe, amusement, and pride as 3 unique emotions is superior to a single-factor model that clusters all 3 emotions together. Structurally, the scales of awe, amusement and pride were invariant across all countries. Furthermore, we found significant country-level differences in dispositional awe, with the largest discrepancy between the United States and Iran (d = 0.79); these differences are not likely due to cultural response biases. Results are discussed in terms of possible explanations for country-level differences and suggestions for future research. (PsycINFO Database Record (c) 2016 APA, all rights reserved).

Culture Moderates Biases in Search Decisions.

Pattaratanakun, Jake A; Mak, Vincent

2015-08-01

Prior studies suggest that people often search insufficiently in sequential-search tasks compared with the predictions of benchmark optimal strategies that maximize expected payoff. However, those studies were mostly conducted in individualist Western cultures; Easterners from collectivist cultures, with their higher susceptibility to escalation of commitment induced by sunk search costs, could exhibit a reversal of this undersearch bias by searching more than optimally, but only when search costs are high. We tested our theory in four experiments. In our pilot experiment, participants generally undersearched when search cost was low, but only Eastern participants oversearched when search cost was high. In Experiments 1 and 2, we obtained evidence for our hypothesized effects via a cultural-priming manipulation on bicultural participants in which we manipulated the language used in the program interface. We obtained further process evidence for our theory in Experiment 3, in which we made sunk costs nonsalient in the search task-as expected, cross-cultural effects were largely mitigated. © The Author(s) 2015.

Professional culture brokers: Nursing faculty perceptions of nursing culture and their role in student formation.

Science.gov (United States)

Strouse, Susan M; Nickerson, Carolyn J

2016-05-01

Socialization, or formation of students to the professional nurse role, is an expectation of nursing education. This process is complex and challenging for students, who continue to experience culture shock moving from academe to practice settings. Viewing formation as enculturation is one way to address culture shock. Nursing faculty are key figures in this process, yet their views are not known. This focused ethnography study explored nursing faculty's perceptions about the culture of nursing and how they bring students into that culture. Data collected at two accredited, undergraduate pre-licensure baccalaureate nursing programs were analyzed using Leininger's four phases of data analysis. Four themes emerged: 1. The culture of nursing is multifaceted, multivalent and at times contradictory 2. Many factors interact and have influence on the culture of nursing 3. Navigating the subcultures (academia, service and organizational culture) is challenging for faculty, and 4. Nursing faculty believe that the right conditions facilitate the enculturation of students. Nursing faculty believe nursing has a professional culture and they bring students into that culture. Viewing the faculty role in enculturation to professional nursing as a culture broker can facilitate the process for students and mitigate the culture shock new graduate nurses experience.

In 2010, The Korea Electric Power Corporation (KEPCO) was awarded a multi-billion dollar bid to construct the first nuclear power plant in Barakah, UAE. One must keep in mind however, that with technology transfer and international cooperation comes a host of potential problems arising from cultural differences such as language, everyday habitudes and workplace expectation. As of now, how problematic these potential issues may become is unknown. Of the aforementioned factors, communication is perhaps of foremost importance. We investigated UAE culture-related issues through analysis of operating experience reviews (OERs) and came to the conclusion that the language barrier needed utmost attention. Korean nuclear power plant operators will work in UAE and will operate the NPPs with operators and managers of other nationalities as well. The purpose of this paper is firstly to confirm that operators are put under mental stress, and secondly to demonstrate the decline in accuracy when they must work in English. Reducing human error is quite important to make nuclear power plants safer. As the mental workload of human operator is increased, the probability of a human error occurring also increases. It will have a negative influence on the plant’s safety. There are many factors which can potentially increase mental workload. We focused on communication problem which is a key factor of increasing mental workload because many Korean operators will work in UAE nuclear power plants and may work together with UAE operators. From these experiments we compared how performance of both Korean and UAE subjects were decreased when they use English. We designed experimental methods to be able to check this problem qualitatively and quantitatively. We analyzed four factors to find the communication problems from the experiments which are accuracy, efficiency, NASA-TLX, and brain wave. Accuracy, efficiency, brain wave are quantitative factors, and NASA-TLX is qualitative factor. To

Plutonium solution storage in plastic bottles: Operational experience and safety issues

International Nuclear Information System (INIS)

Conner, W.V.

1995-01-01

Computer spread sheet models were developed to gain a better understanding of the factors that lead to pressurization and failure of plastic bottles containing plutonium solutions. These models were developed using data obtained from the literature on gas generation rates for plutonium solutions. Leak rates from sealed plastic bottles were obtained from bottle leak tests conducted at Rocky Flats. Results from these bottle leak tests showed that narrow mouth four liter bottles will seal much better than wide mouth four liter bottles. The gas generation rate and leak rate data were used to develop models for predicting the rate of pressurization and maximum pressures expected in sealed bottles of plutonium solution containing various plutonium and acid concentrations. The computer models were used to develop proposed time limits for storing or transporting plutonium solutions in sealed plastic bottles. For plutonium solutions containing 1.5 g/l plutonium, storage in sealed bottles should not be allowed. However, transportation of higher concentration plutonium solution in sealed bottles is required, and safe transportation times of 1 shift to 6 days are proposed

Within- and between-culture variation: individual differences and the cultural logics of honor, face, and dignity cultures.

Science.gov (United States)

Leung, Angela K-Y; Cohen, Dov

2011-03-01

The CuPS (Culture × Person × Situation) approach attempts to jointly consider culture and individual differences, without treating either as noise and without reducing one to the other. Culture is important because it helps define psychological situations and create meaningful clusters of behavior according to particular logics. Individual differences are important because individuals vary in the extent to which they endorse or reject a culture's ideals. Further, because different cultures are organized by different logics, individual differences mean something different in each. Central to these studies are concepts of honor-related violence and individual worth as being inalienable versus socially conferred. We illustrate our argument with 2 experiments involving participants from honor, face, and dignity cultures. The studies showed that the same "type" of person who was most helpful, honest, and likely to behave with integrity in one culture was the "type" of person least likely to do so in another culture. We discuss how CuPS can provide a rudimentary but integrated approach to understanding both within- and between-culture variation. (c) 2011 APA, all rights reserved

Using Culturally Informed Strategies to Enhance Recruitment of African Americans in Dementia Research: A Nurse Researcher's Experience

Directory of Open Access Journals (Sweden)

Fayron Recha Epps

2015-09-01

Full Text Available Decreased research participation hinders advancement in the understanding and treatment of dementia in African Americans. This article describes the experience of a nurse researcher using culturally informed strategies to enhance recruitment in the African American population in southern Louisiana, as part of a study on family involvement in health promotion activities for older adults with dementia. Strategies went beyond having minority recruiters and recruiting from churches to becoming familiar with the context and culture of southern Louisiana through engagement with the community and attaining buy-in from formal and informal contacts. The researcher kept field notes, journals, and a record of recruitment activities to assure accountability during recruitment. An analysis of the field notes revealed the salience of six themes, namely Gaining Trust, Visibility, Networking, Follow-up, Purposeful Activity, and Community Engagement. Barriers that were overcome included knowledge deficit about dementia in the target community and the cultural unsuitability of the terminology linked to dementia. Benefits included community awareness and development of community and family partnerships, and of course, the recruitment of adequate number of research participants.

Viewpoint: Cultural competence and the African American experience with health care: The case for specific content in cross-cultural education.

Science.gov (United States)

Eiser, Arnold R; Ellis, Glenn

2007-02-01

Achieving cultural competence in the care of a patient who is a member of an ethnic or racial minority is a multifaceted project involving specific cultural knowledge as well as more general skills and attitude adjustments to advance cross-cultural communication in the clinical encounter. Using the important example of the African American patient, the authors examine relevant historical and cultural information as it relates to providing culturally competent health care. The authors identify key influences, including the legacy of slavery, Jim Crow discrimination, the Tuskegee syphilis study, religion's interaction with health care, the use of home remedies, distrust, racial concordance and discordance, and health literacy. The authors propose that the awareness of specific information pertaining to ethnicity and race enhances cross-cultural communication and ways to improve the cultural competence of physicians and other health care providers by providing a historical and social context for illness in another culture. Cultural education, modular in nature, can be geared to the specific populations served by groups of physicians and provider organizations. Educational methods should include both information about relevant social group history as well as some experiential component to emotively communicate particular cultural needs. The authors describe particular techniques that help bridge the cross-cultural clinical communication gaps that are created by patients' mistrust, lack of cultural understanding, differing paradigms for illness, and health illiteracy.

1) The plants designed for extracting the plutonium of the G1, G2, G3 reactors fuel rods will produce extremely concentrated solutions of fission products. 2) Let us consider a synthetic solution of the 'G2' type: (2N NO 3 H - 2,25 meq/cm 3 AI +++ - 5.10 -3 134 Cs - 137 Cs tracer). We made various glasses and micas by adding and mixing the necessary adjuvants and baking (900 to 1400 deg. C) in a graphite crucible. 3) The products obtained had either the shape of a cylindrical pellet or were reduced into a fine powder. They were mixed with 300 cm 3 of synthetic sea water during variable periods of time in order to study leaching of the activity. 4) Experiments were first carried on caesium because of its solubility. 5) Fabrication of micas on a large scale sets many technological problems more difficult to solve (1400 deg. C) than in the case of glasses (1000 deg. C). A comparative study on both micas and glasses showed that leaching of activity was more important in the micas. (author) [fr
