The construction of the ideal three-dimensional scaffold for cell culture is one of the most intriguing topics in tissue engineering. It has been shown that cells can be cultured on most organic biomimetic materials, which now are losing popularity in favour of novel, hybrid systems. In this study, a series of photosensitive sol-gel hybrid materials, based on silicon-zirconium and silicon-titanium oxides, have been investigated for their suitability in three-dimensional scaffold fabrication. These materials can be structured by two-photon polymerization, a laser-based technique allowing the fabrication of micrometre-size structures with submicron resolution. The work presented here examined the effect of the organic/inorganic composition of the materials on cell behaviour and the establishment of a 'cell-culture friendly' environment. This is vital for cell adhesion, growth and differentiation, as the organic part of the material provides the soft matrix for cell growth, whereas the inorganic component gives the mechanical stability and rigidity of the three-dimensional structures. In addition, the use of femtosecond laser structuring permits the fabrication of a wide range of mechanically stable scaffolds of different sizes and shapes to be tested in terms of cell viability, proliferation and orientation.

This paper introduces a modified Lue chaotic system, and some basic dynamical properties are studied. Based on these properties, we present hybrid dislocated control method for stabilizing chaos to unstable equilibrium and limit cycle. In addition, based on the Lyapunov stability theorem, general hybrid projective dislocated synchronization (GHPDS) is proposed, which includes complete dislocated synchronization, dislocated anti-synchronization and projective dislocated synchronization as its special item. The drive and response systems discussed in this paper can be strictly different dynamical systems (including different dimensional systems). As examples, the modified Lue chaotic system, Chen chaotic system and hyperchaotic Chen system are discussed. Numerical simulations are given to show the effectiveness of these methods.

Three-dimensional porous scaffolds play an important role in tissue engineering and regenerative medicine. Structurally, these porous scaffolds should have an open and interconnected porous architecture to facilitate a homogeneous cell distribution. Moreover, the scaffolds should be mechanically strong to support new tissue formation. We developed a novel type of funnel-like collagen sponge using embossing ice particulates as a template. The funnel-like collagen sponges could promote the homogeneous cell distribution, ECM production and chondrogenesis. However, the funnel-like collagen sponges deformed during cell culture due to their weak mechanical strength. To solve this problem, we reinforced the funnel-like collagen sponges with a knitted poly(D,L-lactic-co-glycolic acid) (PLGA) mesh by hybridizing these two types of materials. The hybrid scaffolds were used to culture bovine articular chondrocytes. The cell adhesion, distribution, proliferation and chondrogenesis were investigated. The funnel-like structure promoted the even cell distribution and homogeneous ECM production. The PLGA knitted mesh protected the scaffold from deformation during cell culture. Histological and immunohistochemical staining and cartilaginous gene expression analyses revealed the cartilage-like properties of the cell/scaffold constructs after in vivo implantation. The hybrid scaffold, composed of a funnel-like collagen sponge and PLGA mesh, would be a useful tool for cartilage tissue engineering.

Genetic and epigenetic alterations can be invoked by plant tissue culture, which may result in heritable changes in phenotypes, a phenomenon collectively termed somaclonal variation. Although extensive studies have been conducted on the molecular nature and spectrum of tissue culture-induced genomic alterations, the issue of whether and to what extent distinct plant genotypes, e.g., pure-lines, hybrids and polyploids, may respond differentially to the tissue culture condition remains poorly understood. We investigated tissue culture-induced genetic and epigenetic alterations in a set of rice genotypes including two pure-lines (different subspecies), a pair of reciprocal F1 hybrids parented by the two pure-lines, and a pair of reciprocal tetraploids resulted from the hybrids. Using two molecular markers, amplified fragment length polymorphism (AFLP) and methylation-sensitive amplified polymorphism (MSAP), both genetic and DNA methylation alterations were detected in calli and regenerants from all six genotypes, but genetic alteration is more prominent than epigenetic alteration. While significant genotypic difference was observed in frequencies of both types of alterations, only genetic alteration showed distinctive features among the three types of genomes, with one hybrid (N/9) being exceptionally labile. Surprisingly, difference in genetic alteration frequencies between the pair of reciprocal F1 hybrids is much greater than that between the two pure-line subspecies. Difference also exists in the pair of reciprocal tetraploids, but is to a less extent than that between the hybrids. The steady-state transcript abundance of genes involved in DNA repair and DNA methylation was significantly altered in both calli and regenerants, and some of which were correlated with the genetic and/or epigenetic alterations. Our results, based on molecular marker analysis of ca. 1,000 genomic loci, document that genetic alteration is the major cause of somaclonal variation in rice

Jian Zou

2012-11-01

Full Text Available In recent years culture has become one of the most studied topicsin project management research. Some studies have investigatedthe infl uence of culture at different levels – such as nationalculture, industry culture, organisational culture and professionalculture. As a project-based industry, the construction industryneeds to have more insight concerning cultural issues at theproject level and their infl uence on the performance of constructionprojects. Few studies, however, have focused on culture at theproject level. This paper uses a questionnaire survey to determinethe perceptions of Chinese contractors about the impact of projectculture on the performance of local construction projects. This isaugmented by a series of in-depth interviews with senior executivemanagers in the industry. The fi ndings indicate that specifi c projectculture does contribute signifi cantly towards project outcomes.In particular, goal orientation and fl exibility, as two dimensionsof project culture, have a negative statistical correlation withperceived satisfaction of the process, commercial success, futurebusiness opportunities, lessons learnt from the project, satisfactionwith the relationships, and overall performance. This paper alsoindicates that the affordability of developing an appropriate projectculture is a major concern for industry practitioners.

Full Text Available The paper is based upon the research that explored the formation of hybrid cultural identities of five first-generation Turkish immigrants to the United States working in the high-technology sector. Postcolonial theoretical perspective was used to conceptualize the formation of hybrid cultural identities in the globalized world, and Interpretive Phenomenological Analysis was employed to analyze in depth the lived experiences of the participants. The research findings indicated four broad common experiences narrated in the interviews: Shifting Identities, Identities in Comparison, Identities against Power, and Transforming Self. These findings concurred with the postcolonial assumptions that challenged the generalizations of cultural identity in clinical psychology theory and research.

New Method of Selecting Efficient Project Portfolios in the Presence of Hybrid Uncertainty

Directory of Open Access Journals (Sweden)

Bogdan Rębiasz

2016-01-01

Full Text Available A new methods of selecting efficient project portfolios in the presence of hybrid uncertainty has been presented. Pareto optimal solutions have been defined by an algorithm for generating project portfolios. The method presented allows us to select efficient project portfolios taking into account statistical and economic dependencies between projects when some of the parameters used in the calculation of effectiveness can be expressed in the form of an interactive possibility distribution and some in the form of a probability distribution. The procedure for processing such hybrid data combines stochastic simulation with nonlinear programming. The interaction between data are modeled by correlation matrices and the interval regression. Economic dependences are taken into account by the equations balancing the production capacity of the company. The practical example presented indicates that an interaction between projects has a significant impact on the results of calculations. (original abstract

Cheng, Lin; Yang, Yongqing; Li, Li; Sui, Xin

2018-06-01

This paper studies the finite-time hybrid projective synchronization of the drive-response complex networks. In the model, general transmission delays and distributed delays are also considered. By designing the adaptive intermittent controllers, the response network can achieve hybrid projective synchronization with the drive system in finite time. Based on finite-time stability theory and several differential inequalities, some simple finite-time hybrid projective synchronization criteria are derived. Two numerical examples are given to illustrate the effectiveness of the proposed method.

Latino adolescents are at elevated risk for depression and suicide compared to other ethnic groups. Project goals were to gain insight from community leaders about depression risk factors particular to Latino adolescents and generate innovative suggestions to improve cultural relevance of prevention interventions. This project utilized a CBPR approach to enhance cultural relevance, acceptability, and utility of the findings and subsequent program development. Two focus groups of youth and youth-involved Latino community leaders (n = 18) yielded three overarching themes crucial to a culturally tailored depression prevention intervention: (1) utilize a multipronged and sustainable intervention approach, (2) raise awareness about depression in culturally meaningful ways, and (3) promote Latino youth's social connection and cultural enrichment activities. Findings suggest that both adaptation of existing prevention programs and development of hybrid approaches may be necessary to reduce depression/suicide disparities for Latino youth. One such hybrid program informed by community stakeholders is described.

Organized Communities as a Hybrid Form of Data Sharing: Experiences from the Global STEP Project

Full Text Available With this article, I explore a new way of how social scientists can share primary qualitative data with each other. More specifically, I examine organized research communities, which are small membership groups of scholars. This hybrid form of data sharing is positioned between informal sharing through collaboration and institutionalized sharing through accessing research archives. Using the global "Successful Transgenerational Entrepreneurship Practices" (STEP project as an example, I draw attention to the pragmatic practices of data sharing in such communities. Through ongoing negotiations, organized communities can, at least temporarily, put forward sharing policies and create a culture of data sharing that elevates the re-use of qualitative data while being mindful of the data's intersubjective and processual character.

This study describes the isolation and pathogenicity of Streptococcus iniae in cultured red hybrid tilapia (Nile Tilapia Oreochromis niloticus × Mozambique Tilapia O. mossambicus) in Malaysia. The isolated gram-positive S. iniae appeared punctiform, transparently white, catalase and oxidase negative and produced complete β-hemolysis on blood agar, while a PCR assay resulted in the amplification of the 16 S rRNA gene and lactate oxidase encoded genes. The isolate was sensitive to tetracycline, vancomycin, and bacitracin but was resistant to streptomycin, ampicillin, penicillin, and erythromycin. Pathogenicity trials conducted in local red hybrid tilapia (mean ± SE = 20.00 ± 0.45 g) showed 90.0, 96.7, and 100.0% mortality within 14 d postinfection following intraperitoneal exposure to 10 4 , 10 6 , and 10 8 CFU/mL of the pathogen, respectively. The clinical signs included erratic swimming, lethargy, and inappetance at 6 h postinfection, while mortality was recorded at less than 24 h postinfection in all infected groups. The LD 50-336 h of S. iniae against the red hybrid tilapia was 10 2 CFU/mL. The post mortem examinations revealed congested livers, kidneys, and spleens of the infected fish. This is the first report of S. iniae experimental infection in cultured red hybrid tilapia in Malaysia. Received January 20, 2017; accepted July 16, 2017.

'CosmoCult Card Game': A Methodological Tool to Understand the Hybrid and Peripheral Cultural Consumption of Young People

Directory of Open Access Journals (Sweden)

Wilson Roberto Bekesas

2018-04-01

Full Text Available This article discusses the authors’ use of a specially designed card game as part of the survey ‘Youth Cosmopolitanisms in Brazil’, a constituent part of the international project ‘Cultures Juveniles à l’ère de la globalization’, developed in France. As part of the challenges encountered in the process of applying this project in a hybrid and post-colonial context, such as that of Brazil, we experienced different manifestations of what Angela Prysthon (2002 has called ‘peripheral cosmopolitanism’. We propose to present the experiences that resulted as contributory material for research on the cultural consumption of young people in such contexts, and to discuss the value of this research tool as a way to reach and understand spontaneous cultural references, within the subjects’ own conceptions, without the bias that a Western-centered perspective might introduce. Concerning the card game as a research tool, it seems that only recently, and still modestly, have games been thought of in a broader sense of learning and research (Girard, Ecalle & Magnan, 2012; Calvillo Gámez et al., 2011. This moves us to consider the potential that it has for our and others’ research that seeks a methodological tool that reduces cultural biases and borders. Among the examples from the 12- to 24-year-old research subjects, the narratives display their relationships with global and local elements, such as the use of a Brazilian song, ‘Atoladinha’, or Harry Potter characters, used to solve situations proposed in the game.

Full Text Available Six Sigma is a project-driven methodology; the projects that provide the maximum financial benefits and other impacts to the organization must be prioritized. Project selection (PS is a type of multiple criteria decision making (MCDM problem. In this study, we present a hybrid MCDM model combining the decision-making trial and evaluation laboratory (DEMATEL technique, analytic network process (ANP, and the VIKOR method to evaluate and improve Six Sigma projects for reducing performance gaps in each criterion and dimension. We consider the film printing industry of Taiwan as an empirical case. The results show that our study not only can use the best project selection, but can also be used to analyze the gaps between existing performance values and aspiration levels for improving the gaps in each dimension and criterion based on the influential network relation map.

Projective and hybrid projective synchronization for the Lorenz-Stenflo system with estimation of unknown parameters

International Nuclear Information System (INIS)

Mukherjee, Payel; Banerjee, Santo

2010-01-01

In this work, in the first phase, we study the phenomenon of projective synchronization in the Lorenz-Stenflo system. Synchronization is then investigated for the same system with unknown parameters. We show analytically that synchronization is possible for some proper choice of the nonlinear controller by using a suitable Lyapunov function. With the help of this result, it is also possible to estimate the values of the unknown system parameters. In the second phase as an extension of our analysis, we investigate the new hybrid projective synchronization for the same system. All our analyses are well supported with numerical evidence.

An artificial three-dimensional (3D) culture system that mimics the tumor microenvironment in vitro is an essential tool for investigating the cross-talk between immune and cancer cells in tumors. In this study, we developed a 3D culture system using an electrospun poly(ε-caprolactone) (PCL) nanofibrous scaffold (NFS). A hybrid NFS containing an uninterrupted network of nano- and submicron-scale fibers (400 nm to 2 µm) was generated by deposition onto a stainless steel mesh instead of an aluminum plate. The hybrid NFS contained multiplanar pores in a 3D structure. Surface-seeded mouse CT26 colon cancer cells and bone marrow-derived dendritic cells (BM-DCs) were able to infiltrate the hybrid NFS within several hours. BM-DCs cultured on PCL nanofibers showed a baseline inactive form, and lipopolysaccharide (LPS)-activated BM-DCs showed increased expression of CD86 and major histocompatibility complex Class II. Actin and phosphorylated FAK were enriched where unstimulated and LPS-stimulated BM-DCs contacted the fibers in the 3D hybrid NFS. When BM-DCs were cocultured with mitoxantrone-treated CT26 cells in a 3D hybrid NFS, BM-DCs sprouted cytoplasm to, migrated to, synapsed with, and engulfed mitoxantrone-treated CT26 cancer cells, which were similar to the naturally occurring cross-talk between these two types of cells. The 3D hybrid NFS developed here provides a 3D structure for coculture of cancer and immune cells. PMID:27042051

Barbier, Michele

2016-04-01

Scientific Projects today have increased in complexity, requiring multidisciplinarity, and requiring a mix of diverse individuals from different countries who must be integrated into an effective project. Effective team building is one of the prime responsibilities of the project manager. When the project is supported by a funding, the integration and the implication of the different partners are quite easy. Particularly when partners are developing high-performing teams. However, management of research project requires further skills when the budget is not very high and/or when partners are from non-European countries and are not using the same vocabulary. The various cultures, values, beliefs and social usages, particularly with Mediterranean countries cause a special style of communication for an individual or group of individuals. This communication style participates in the success of the project and encompasses a lot of diplomatic skills which will be highlighted.

Full Text Available The interactions between the project manager and team members may be affected by several variables, such as culture, leadership style of the project manager, and the complexity of the developed tasks. Focused in this context, the objective of this paper is to investigate and describe how the culture issue can affect the anagement of global project teams. It is a qualitative, descriptive study conducted in a large multinational company in the automotive sector. The results of this research show that cultural issues can influence both positively and negatively the management of project global teams and the managers of these projects have to deal with several management challenges that require the adoption of certain ways of dealing with culture impacts in managing their teams to minimize potential problems in this context.

Full Text Available This article focuses on the hybrid and how it is put into perspective on Prospero’s island. First Caliban is examined as both a biological and cultural hybrid pervading the imaginary field and as the touchstone of the related dialectics of rejection and appropriation. Then, from a metaphorical point of view, Prospero’s island is regarded as a cabinet of curiosities in which hybrid creatures—of which Caliban is one—fill the castaways with either wonder or horror; Prospero’s project and that of creators of cabinets as “encyclopaedias of the visible world” (Evans’ phrase may hence be paralleled. Finally, the hybrid as revealing hubris, Prospero’s “Promethean attitude” (Hadot’s term and the irreducible quality of the hybrid are examined.

One of the goals of the HYBRID modeling and simulation project is to assess the economic viability of hybrid systems in a market that contains renewable energy sources like wind. The idea is that it is possible for the nuclear plant to sell non-electric energy cushions, which absorb (at least partially) the volatility introduced by the renewable energy sources. This system is currently modeled in the Modelica programming language. To assess the economics of the system, an optimization procedure is trying to find the minimal cost of electricity production. The RAVEN code is used as a driver for the whole problem. It is assumed that at this stage, the HYBRID modeling and simulation framework can be classified as non-safety “research and development” software. The associated quality level is Quality Level 3 software. This imposes low requirements on quality control, testing and documentation. The quality level could change as the application development continues.Despite the low quality requirement level, a workflow for the HYBRID developers has been defined that include a coding standard and some documentation and testing requirements. The repository performs automated unit testing of contributed models. The automated testing is achieved via an open-source python script called BuildingsP from Lawrence Berkeley National Lab. BuildingsPy runs Modelica simulation tests using Dymola in an automated manner and generates and runs unit tests from Modelica scripts written by developers. In order to assure effective communication between the different national laboratories a biweekly videoconference has been set-up, where developers can report their progress and issues. In addition, periodic face-face meetings are organized intended to discuss high-level strategy decisions with management. A second means of communication is the developer email list. This is a list to which everybody can send emails that will be received by the collective of the developers and managers

Improving intercultural competency in global IT projects through recognition of culture-based behaviors

Directory of Open Access Journals (Sweden)

Richard Amster

2016-01-01

Full Text Available The success of global IT projects is highly influenced by culture-based behaviors. Issues between individuals arise when behaviors are (mis-perceived, (mis-interpreted, and (mis-judged by using the perceiver’s expectations, beliefs, and values. Misperception results when the behavior is not anticipated because it would not occur in ones own culture. As a result, behavior should be the starting point for cross-cultural research. But, studies have primarily focused on belief and value systems which are more abstract and less specific than behaviors. This paper presents a study that analyzed cultural behavioral differences between Indian project managers and their counterparts in other countries. The conducted qualitative, semi-structured interviews revealed insights into cross-cultural challenges and shed light on the complex ways that culture-based behaviors impact IT projects. The study identified 127 behaviors that significantly affected project success and cross-cultural cooperation between Indian managers and managers from all over the world. These behaviors were grouped into 19 behavior clusters. Understanding these behavior clusters, and correlating these behaviors to values and beliefs, will improve project collaboration, and inform cross-cultural training strategies. In addition, existing cultural dimensions were reduced in scope, additional dimensions were defined for clarity, and new business-related dimensions were identified. Finally, based on the study’s results, the paper suggests four important components that should be added to cross-cultural training programs for international project managers.

Lowe, Andrew; Hayward, Brent (Dedale Asia Pacific, Albert Park VIC 3206 (Australia))

2006-08-15

This report documents a study with the objective of enhancing safety culture in the Swedish nuclear power industry. A primary objective of this study was to ensure that the latest thinking on human factors principles was being recognised and applied by nuclear power operators as a means of ensuring optimal safety performance. The initial phase of the project was conducted as a pilot study, involving the senior management group at one Swedish nuclear power-producing site. The pilot study enabled the project methodology to be validated after which it was repeated at other Swedish nuclear power industry sites, providing a broad-ranging analysis of opportunities across the industry to enhance safety culture. The introduction to this report contains an overview of safety culture, explains the background to the project and sets out the project rationale and objectives. The methodology used for understanding and analysing the important safety culture issues at each nuclear power site is then described. This section begins with a summary of the processes used in the information gathering and data analysis stage. The six components of the Management Workshops conducted at each site are then described. These workshops used a series of presentations, interactive events and group exercises to: (a) provide feedback to site managers on the safety culture and safety leadership issues identified at their site, and (b) stimulate further safety thinking and provide 'take-away' information and leadership strategies that could be applied to promote safety culture improvements. Section 3, project Findings, contains the main observations and output from the project. These include: - a brief overview of aspects of the local industry operating context that impinge on safety culture; - a summary of strengths or positive attributes observed within the safety culture of the Swedish nuclear industry; - a set of identified opportunities for further improvement; - the aggregated

The target of the Roadrunner Universe project at Los Alamos National Laboratory is a set of very large cosmological N-body simulation runs on the hybrid supercomputer Roadrunner, the world's first petaflop platform. Roadrunner's architecture presents opportunities and difficulties characteristic of next-generation supercomputing. We describe a new code designed to optimize performance and scalability by explicitly matching the underlying algorithms to the machine architecture, and by using the physics of the problem as an essential aid in this process. While applications will differ in specific exploits, we believe that such a design process will become increasingly important in the future. The Roadrunner Universe project code, MC 3 (Mesh-based Cosmology Code on the Cell), uses grid and direct particle methods to balance the capabilities of Roadrunner's conventional (Opteron) and accelerator (Cell BE) layers. Mirrored particle caches and spectral techniques are used to overcome communication bandwidth limitations and possible difficulties with complicated particle-grid interaction templates.

Hu Manfeng; Xu Zhenyuan; Zhang Rong; Hu Aihua

2007-01-01

This Letter further investigates the full state hybrid projective synchronization (FSHPS) of chaotic and hyper-chaotic systems with fully unknown parameters. Based on the Lyapunov stability theory, a unified adaptive controller and parameters update law can be designed for achieving the FSHPS of chaotic and/or hyper-chaotic systems with the same and different order. Especially, for two chaotic systems with different order, reduced order MFSHPS (an acronym for modified full state hybrid projective synchronization) and increased order MFSHPS are first studied in this Letter. Five groups numerical simulations are provided to verify the effectiveness of the proposed scheme. In addition, the proposed FSHPS scheme is quite robust against the effect of noise

Safety Culture in New Build Projects

International Nuclear Information System (INIS)

Reiman, T.

2016-01-01

The concept of culture emphasises the social factors that have an effect on the way hazards are perceived, risks are evaluated, risk management is conducted, the current safety level is interpreted, and what is considered normal and what abnormal. It also contributes to defining the correct ways to behave in situations and correct ways to talk about safety, risks or uncertainty. Culture is something the company has created for itself that then has an effect on the company. This effect is not necessarily perceived by the company itself, since the members of the organization consider all things that happen according to their cultural taken-for-granted assumptions (“business as usual”). Thus, safety culture can either hinder or advance nuclear safety. This depends on what the shared values and assumptions are, and how they are in line with, and influence, the organizational structures, practices, personnel and technology. Safety culture requires constant and systematic development, monitoring and review during the entire life-cycle of a nuclear facility. The pre-operational phase sets many unique requirements for nuclear safety culture. For example, some of the organizations and individuals involved in the project may have no insight on how safety culture relates to nuclear power plants. Companies that work in the conventional industry typically associate safety with occupational safety issues, not with nuclear safety. Further, it may be unclear how the construction phase affects nuclear safety of an operating plant. When workers are asked to perform their work differently than previously (e.g., in conventional construction sites), explanation has to be given. For example, structures, systems and components may have different functions during emergency that exceed or differ from their quality requirements during normal operation. The strict quality requirements and use of certain methods and procedures, documentation requirements, etc., may seem unimportant if

Navigating hybridity: investigating the dance between culture and values within the cuban national education system.

Full Text Available Hybridity is the dynamic relationship between local and global factors that push and pull on people and nations. Hybridity is deeply situated in socio-contextual factors, like cultural beliefs, education, and political systems, that aid and hinder a people’s navigation of globalized phenomena. Simply put, hybridity is how people and societies adapt to a changing world. This article examines the case of Cuba in response to hybridity. Specifically, the article’s purpose is to examine ways that the Cuban National Education System impacts how Cubans navigate the global march towards hybridity. The article reports on a focused ethnographic study of a week long education trip to Cuba during February 2013. The ethnography includes over 100 hours of data collection, including semi-structured interviews with 26 Cuban participants. The study uses Freire’s (1970 notion of “humanizing pedagogy” to analyze how the impact of the Cuban National Education System values in the context of Cuba and larger global context. The study found that three values in particular, amor, solidaridad, and conciencia de derechos y response, were deeply embedded in the Cuban National Education System and effect the way that Cubans navigate the complex hybridity that situates their island nation.

Disturbance observer-based adaptive sliding mode hybrid projective synchronisation of identical fractional-order financial systems

Science.gov (United States)

Khan, Ayub; Tyagi, Arti

2018-05-01

In this paper, we have studied the hybrid projective synchronisation for incommensurate, integer and commensurate fractional-order financial systems with unknown disturbance. To tackle the problem of unknown bounded disturbance, fractional-order disturbance observer is designed to approximate the unknown disturbance. Further, we have introduced simple sliding mode surface and designed adaptive sliding mode controllers incorporating with the designed fractional-order disturbance observer to achieve a bounded hybrid projective synchronisation between two identical fractional-order financial model with different initial conditions. It is shown that the slave system with disturbance can be synchronised with the projection of the master system generated through state transformation. Simulation results are presented to ensure the validity and effectiveness of the proposed sliding mode control scheme in the presence of external bounded unknown disturbance. Also, synchronisation error for commensurate, integer and incommensurate fractional-order financial systems is studied in numerical simulation.

Hybrid Multicriteria Group Decision Making Method for Information System Project Selection Based on Intuitionistic Fuzzy Theory

2013-01-01

Full Text Available Information system (IS project selection is of critical importance to every organization in dynamic competing environment. The aim of this paper is to develop a hybrid multicriteria group decision making approach based on intuitionistic fuzzy theory for IS project selection. The decision makers’ assessment information can be expressed in the form of real numbers, interval-valued numbers, linguistic variables, and intuitionistic fuzzy numbers (IFNs. All these evaluation pieces of information can be transformed to the form of IFNs. Intuitionistic fuzzy weighted averaging (IFWA operator is utilized to aggregate individual opinions of decision makers into a group opinion. Intuitionistic fuzzy entropy is used to obtain the entropy weights of the criteria. TOPSIS method combined with intuitionistic fuzzy set is proposed to select appropriate IS project in group decision making environment. Finally, a numerical example for information system projects selection is given to illustrate application of hybrid multi-criteria group decision making (MCGDM method based on intuitionistic fuzzy theory and TOPSIS method.

Mapping epistemic cultures and learning potential of participants in citizen science projects.

2016-06-01

The ever-widening scope and range of global change and interconnected systemic risks arising from people-environment relationships (social-ecological risks) appears to be increasing concern among, and involvement of, citizens in an increasingly diversified number of citizen science projects responding to these risks. We examined the relationship between epistemic cultures in citizen science projects and learning potential related to matters of concern. We then developed a typology of purposes and a citizen science epistemic-cultures heuristic and mapped 56 projects in southern Africa using this framework. The purpose typology represents the range of knowledge-production purposes, ranging from laboratory science to social learning, whereas the epistemic-cultures typology is a relational representation of scientist and citizen participation and their approach to knowledge production. Results showed an iterative relationship between matters of fact and matters of concern across the projects; the nexus of citizens' engagement in knowledge-production activities varied. The knowledge-production purposes informed and shaped the epistemic cultures of all the sampled citizen science projects, which in turn influenced the potential for learning within each project. Through a historical review of 3 phases in a long-term river health-monitoring project, we found that it is possible to evolve the learning curve of citizen science projects. This evolution involved the development of scientific water monitoring tools, the parallel development of pedagogic practices supporting monitoring activities, and situated engagement around matters of concern within social activism leading to learning-led change. We conclude that such evolutionary processes serve to increase potential for learning and are necessary if citizen science is to contribute to wider restructuring of the epistemic culture of science under conditions of expanding social-ecological risk. © 2016 Society for

General hybrid projective complete dislocated synchronization with non-derivative and derivative coupling based on parameter identification in several chaotic and hyperchaotic systems

International Nuclear Information System (INIS)

Sun Jun-Wei; Shen Yi; Zhang Guo-Dong; Wang Yan-Feng; Cui Guang-Zhao

2013-01-01

According to the Lyapunov stability theorem, a new general hybrid projective complete dislocated synchronization scheme with non-derivative and derivative coupling based on parameter identification is proposed under the framework of drive-response systems. Every state variable of the response system equals the summation of the hybrid drive systems in the previous hybrid synchronization. However, every state variable of the drive system equals the summation of the hybrid response systems while evolving with time in our method. Complete synchronization, hybrid dislocated synchronization, projective synchronization, non-derivative and derivative coupling, and parameter identification are included as its special item. The Lorenz chaotic system, Rössler chaotic system, memristor chaotic oscillator system, and hyperchaotic Lü system are discussed to show the effectiveness of the proposed methods. (general)

Advanced Hybrid Particulate Collector Project Management Plan

Energy Technology Data Exchange (ETDEWEB)

Miller, S.J.

1995-11-01

As the consumption of energy increases, its impact on ambient air quality has become a significant concern. Recent studies indicate that fine particles from coal combustion cause health problems as well as atmospheric visibility impairment. These problems are further compounded by the concentration of hazardous trace elements such as mercury, cadmium, selenium, and arsenic in fine particles. Therefore, a current need exists to develop superior, but economical, methods to control emissions of fine particles. Since most of the toxic metals present in coal will be in particulate form, a high level of fine- particle collection appears to be the best method of overall air toxics control. However, over 50% of mercury and a portion of selenium emissions are in vapor form and cannot be collected in particulate control devices. Therefore, this project will focus on developing technology not only to provide ultrahigh collection efficiency of particulate air toxic emissions, but also to capture vapor- phase trace metals such as mercury and selenium. Currently, the primary state-of-the-art technologies for particulate control are fabric filters (baghouses) and electrostatic precipitators (ESPs). However, they both have limitations that prevent them from achieving ultrahigh collection of fine particulate matter and vapor-phase trace metals. The objective of this project is to develop a highly reliable advanced hybrid particulate collector (AHPC) that can provide > 99.99 % particulate collection efficiency for all particle sizes between 0.01 and 50 14m, is applicable for use with all U.S. coals, and is cost-0443competitive with existing technologies. Phase I of the project is organized into three tasks: Task I - Project Management, Reporting, and Subcontract Consulting Task 2 - Modeling, Design, and Construction of 200-acfm AHPC Model Task 3 - Experimental Testing and Subcontract Consulting

Factors Influencing the Tissue Culture and the Agrobacterium tumefaciens-Mediated Transformation of Hybrid Aspen and Poplar Clones.

Science.gov (United States)

De Block, M

1990-07-01

Tissue culture conditions and transformation have been established for both aspen and poplar. The use of previously described culture conditions resulted in shoot tip necrosis in the shoot cultures and necrosis of stem and leaf explants. Shoot tip necrosis could be overcome by buffering the medium with 2-(N-morpholino)ethanesulfonic acid and Ca-gluconate and by growing the shoots below 25 degrees C. Necrosis of the explants was probably due to an accumulation of ammonium in the explants and could be overcome by adapting the NO(3) (-)/NH(4) (+) ratio of the media. Stem explants of established shoot cultures of the aspen hybrid Populus alba x P. tremula and of the poplar hybrid Populus trichocarpa x P. deltoides were cocultivated with Agrobacterium strains having chimeric bar and neo genes on their disarmed tDNAs. Transformed aspen shoots were obtained from 30 to 40% of the explants, while transformed poplar shoots were obtained from 10% of the explants. Extracts from the transformed trees contained high phosphinotricin acetyltransferase and neomycin phosphotransferase activities, and the trees contained one to three copies of the chimeric genes. The transformed trees were completely resistant to the commercial preparations of the herbicide phosphinotricin (glufosinate), while control trees were not.

Ramnarain, Umesh; de Beer, Josef

2013-02-01

In this paper, we report on the experiences of three 9th-grade South African students (13-14 years) in doing open science investigation projects for a science expo. A particular focus of this study was the manner in which these students merge the world of school science with their social world to create a hybrid space by appropriating knowledge and resources of the school and home. Within this hybrid space they experienced a deeper, more meaningful and authentic engagement in science practical work. This hybrid space redefined the landscape of the science learning experience for these students, as they could derive the twofold benefit of appropriating support when necessary and at the same time maintain their autonomy over the investigation. For South Africa and quite probably other countries; these findings serve as a guideline as to how opportunities can be created for students to do open science investigations, against prevailing school factors such as large classes, a lack of physical resources, the lack of time for practical work and the demands of syllabus coverage.

Full Text Available The Dearfield Dream Project is a collaborative research initiative to conduct historical, cultural, archaeological, and environmental studies on the early 20th Century African-American colony site of Dearfield, Colorado, USA. Because the breadth and significance of the Dearfield Project requires an interdisciplinary research team, a network of research collaborators has been assembled. This research network seeks to discover, preserve, and disseminate knowledge of the site and its surrounding farmsteads’ economic, social, political, and environmental history for better understanding and interpretation of its contributions to Colorado and U.S. history. Herein, we detail progress that has been made on this important historical/cultural research project. Further, we outline the future of the Dearfield research network along with our current and anticipated subjects of inquiry.

Culturally appropriate organization of water and sewerage projects built through public private partnerships.

Jessica A Kaminsky

Full Text Available This paper contributes to the pursuit of socially sustainable water and sanitation infrastructure for all people by discovering statistically robust relationships between Hofstede's dimensions of cross-cultural comparison and the choice of contract award types, project type, and primary revenue sources. This analysis, which represents 973 projects distributed across 24 low- and middle-income nations, uses a World Bank dataset describing high capital cost water and sewerage projects funded through private investment. The results show that cultural dimensions explain variation in the choice of contract award types, project type, and primary revenue sources. These results provide empirical evidence that strategies for water and sewerage project organization are not culturally neutral. The data show, for example, that highly individualistic contexts are more likely to select competitive contract award types and to depend on user fees to provide the primary project revenue stream post-construction. By selecting more locally appropriate ways to organize projects, project stakeholders will be better able to pursue the construction of socially sustainable water and sewerage infrastructure.

These results provide empirical evidence that strategies for water and sewerage project organization are not culturally neutral. The data show, for example, that highly individualistic contexts are more likely to select competitive contract award types and to depend on user fees to provide the primary project revenue stream post-construction. By selecting more locally appropriate ways to organize projects, project stakeholders will be better able to pursue the construction of socially sustainable water and sewerage infrastructure.

Full Text Available The article describes the genetic structure of 12-year old seedlings. They were grown in an experimental culture representing the progeny of natural hybrids of Pinus mugo Turra and Pinus sylvestris L. from the peatbog Bór na Czerwonem. The studies were carried out on seedlings, employing electrophoresis of enzymatic proteins from winter buds. Parallel isoenzymatic analyses were also conducted for trees of P. mugo Turra from Tatra Mountains and for P. sylvestris L. trees from Białowieża in order to determine similarities of the hybrids to the 'pure' species, thought to represent parental forms, and for natural hybrids from Bór na Czerwonem. The obtained electrophoretic patterns made the determination of genetic structure of the population possible, namely of the observed heterozygosity, expected heterozygosity, Wright's fixation index and coefficients of similarity according to Nei and Hedrick. Genetic distances between the populations were also estimated. The variability of 11 enzymatic loci demonstrated the highest level of variability in the population of hybrids. Coefficients of genetic differentiation (GST and of gene flow, (Nm suggested a close relationship of the hybrids to P. mugo which may indicate an introgressive type of the hybrid swarm, from which the studied trees originated. The analysis of genetic similarity coefficients, according to Nei and Hedrick, demonstrated also an extensive similarity of the two hybrid groups to P. mugo. However, upon analysis of individual enzymatic loci, some of them highly resembled P. mugo while others were similar to P. sylvestris. The closest genetic similarity was demonstrated for the group of hybrids from the peatbog and the respective of hybrides group from culture. The variable gene expression as well as asymmetric inheritance of isoenzymes provided additional evidence of the introgressive character of the studied trees from the hybrid population.

Ulla Santti

2017-08-01

Full Text Available Previous research has shown that links between organizational culture and innovativeness/performance may act as a “social glue” that helps a company develop organizational culture as a competitive advantage. In this study of three case companies, the organizational culture change due business model development projects is studied using the Competing Values Framework (CVF tool and interviews with respondents about discovered changes. To reveal intervention and implied effects between business model development project and organizational culture changes, we used CIMO logic (context, intervention, mechanism, and outcome to bridge practice and theory by explanatory, backward-looking research. Our case studies of companies in relatively short-duration business model development projects indicate that organizational culture may have some dynamic characteristics, for example, an increase of the adhocracy organizational type in all case companies or an increase in the hierarchical leadership type in one case company. Thus, the development of an organizational culture type can be partly controlled. Our results also indicated business model development projects do have a minor effect on organizational culture, even when development activities have not been put fully into practice. However, the more comprehensively business model development project activities have been put into practice, the larger the effect on organizational culture.

Research highlights: → Multi-objective optimization model of short-term environmental/economic hydrothermal scheduling. → A hybrid multi-objective cultural algorithm (HMOCA) is presented. → New heuristic constraint handling methods are proposed. → Better quality solutions by reducing fuel cost and emission effects simultaneously are obtained. -- Abstract: The short-term environmental/economic hydrothermal scheduling (SEEHS) with the consideration of multiple objectives is a complicated non-linear constrained optimization problem with non-smooth and non-convex characteristics. In this paper, a multi-objective optimization model of SEEHS is proposed to consider the minimal of fuel cost and emission effects synthetically, and the transmission loss, the water transport delays between connected reservoirs as well as the valve-point effects of thermal plants are taken into consideration to formulate the problem precisely. Meanwhile, a hybrid multi-objective cultural algorithm (HMOCA) is presented to deal with SEEHS problem by optimizing both two objectives simultaneously. The proposed method integrated differential evolution (DE) algorithm into the framework of cultural algorithm model to implement the evolution of population space, and two knowledge structures in belief space are redefined according to the characteristics of DE and SEEHS problem to avoid premature convergence effectively. Moreover, in order to deal with the complicated constraints effectively, new heuristic constraint handling methods without any penalty factor settings are proposed in this paper. The feasibility and effectiveness of the proposed HMOCA method are demonstrated by two case studies of a hydrothermal power system. The simulation results reveal that, compared with other methods established recently, HMOCA can get better quality solutions by reducing fuel cost and emission effects simultaneously.

Place and culture-based professional development: cross-hybrid learning and the construction of ecological mindfulness

Science.gov (United States)

Chinn, Pauline W. U.

2015-03-01

This paper approaches mindfulness, an awareness of internal and external realities, as a culturally-shaped habit of mind. Findings of a cross-cultural study and popular sayings that reflect America's cultural orientation to consumption and competition are contrasted with findings from Hawaiian language newspapers, traditional cultural practices, and Hawaiian sayings that indicate an orientation to ecological mindfulness that increased the resilience of fragile social ecosystems. Marginalization of indigenous culture, language, and knowledge and cultural differences between teachers and indigenous students are proposed as a contributing factor to lower science performance of Native Hawaiian students in mainstream schools. Two professional development projects designed to reduce conflicts between culture and science instruction are presented. Findings from these projects suggest alignment of science inquiry with indigenous cultural knowledge and practices oriented to sustainability supports the development of teachers' ecological mindfulness as indicated by increased awareness of, interest in, and incorporation of place and culture-based based resources into their instruction. Teacher feedback indicates that mapping technologies that enable teachers to visualize and integrate indigenous place-based Hawaiian knowledge with science inquiry are promising instructional strategies.

Approach to assessing local socio-cultural impacts using projections of population growth and composition

Energy Technology Data Exchange (ETDEWEB)

Baldwin, T. E.; Poetsch, R.

1977-08-01

All assessment of future domestic development projects assumes that the problems to be examined have been properly identified and defined before the application of a projection technique. An attempt is made to codify socio-cultural problems mentioned in literature and clarify how existing demographic projection techniques can be applied to assessing the problems. The relationship between changes in local population size and composition induced by in-migration and the potential for socio-cultural incompatibilities is described heuristically. For simplification, the problems expected to emerge from differences in demographic composition are classified into three categories: (1) service needs, such as those for housing, recreation, and education; (2) types of social organizations related to capacities for, or constraints on, reaping the benefits of rapid economic development and social changes (e.g., employment and income); and (3) attitudes, values, and cultural perspectives. These areas of concern are very broad, and quantitative projections of population size and composition are more easily related to the first than to the third. Although demographic projection provides a valuable tool for estimating future social change, the knowledge about cause and effect is not sufficient to support the quantification of socio-cultural impact. Therefore, the projections are used only as relative indicators and the assessments of socio-cultural impact based on them are qualitative only. Therefore, identification and assessment of socio-cultural impacts are a means of developing plans to overcome the expected problems.

Epistemology And The Problem Of Cultural Hybridity In Muhammad Iqbal’s Thought

Full Text Available Abstract : The hegemony of rational-positivistic paradigm of modern Western epistemology contributes greatly to  the  development  of  modern  thought.  The  paradigm,  so  far,  brings  knowledge  and  science  into mere instrumental goals. Scientism is the result of the paradigm which lost of its sacred as science. Therefore,  it  gets  philosophical  attack  from  both  Western  postmodern  thinkers  and  indigenous scholars who already experienced Western colonialism and imperialism. One of the Moslem scholars who criticized the hegemony of Western thought to Islamic culture and civilization is Muhammad Iqbal. For Iqbal, for centuries, Muslim thinkers were unable to see Islam from Quran point of view because they perceive it from the eye of rational-speculative Greek philosophy. Islamic thinking had been under its hegemony for so long that need to be deconstructed. In the postcolonial perspective, Iqbal’s  attempt  to  decolonize  Western  rational-speculative  epistemology  from  Plato  to  Descartes found  him  in  ambivalence.  British  colonialism  experienced  by  Iqbal  in  India  formed  the  hybrid culture in his project of reconstructing Islamic thought in relation to Western thought. Therefore, Iqbal’s  attempt  to  bridge  the  gap  between  rational-speculative  of  Western  thought  and  mystic- religious tendencies of Islamic thought is a process of seeking “the Third Space” through mimicry as consequence of cultural interaction between the colonizer and the colonized.

A Hybrid Instance Selection Using Nearest-Neighbor for Cross-Project Defect Prediction

Institute of Scientific and Technical Information of China (English)

Duksan Ryu; Jong-In Jang; Jongmoon Baik; Member; ACM; IEEE

2015-01-01

Software defect prediction (SDP) is an active research field in software engineering to identify defect-prone modules. Thanks to SDP, limited testing resources can be effectively allocated to defect-prone modules. Although SDP requires suffcient local data within a company, there are cases where local data are not available, e.g., pilot projects. Companies without local data can employ cross-project defect prediction (CPDP) using external data to build classifiers. The major challenge of CPDP is different distributions between training and test data. To tackle this, instances of source data similar to target data are selected to build classifiers. Software datasets have a class imbalance problem meaning the ratio of defective class to clean class is far low. It usually lowers the performance of classifiers. We propose a Hybrid Instance Selection Using Nearest-Neighbor (HISNN) method that performs a hybrid classification selectively learning local knowledge (via k-nearest neighbor) and global knowledge (via na¨ıve Bayes). Instances having strong local knowledge are identified via nearest-neighbors with the same class label. Previous studies showed low PD (probability of detection) or high PF (probability of false alarm) which is impractical to use. The experimental results show that HISNN produces high overall performance as well as high PD and low PF.

Tangible cultural heritage includes various categories of monuments and sites, from cultural landscapes and sacred sites to archaeological complexes, individual architectural or artistic monuments and historic urban centers. Such places are continuously impacted and weathered by several internal and external factors, both natural and human-induced, with rapid and/or slow onset, including natural hazards, such as earthquakes or extreme meteorological events, cumulative processes as well as the effects of humans, especially in conflict situations. A clear picture of endangered sites is not available. In particular, the list of List of World Heritage in danger mainly focuses on sites threaten by armed conflicts. New space technology based on radar interferometry (InSAR) is now capable to monitor, since 1992 and with mm precision, surface deformation for reflective targets named persistent scatterers, which consistently return stable signals to the radar satellites. Led by the Italian Institute for Environmental Protection and Research, and in collaboration with NERC British Geological Survey, Geological and Mining Institute of Spain, University of Milano-Bicocca and Cyprus University of Technology, the project PROTHEGO, co-funded in the framework of JPI on Cultural Heritage EU programme (2015-2018), will make an innovative contribution towards the analysis of geo-hazards in areas of cultural heritage in Europe. The project will apply novel InSAR techniques to monitor monuments and sites that are potentially unstable due to landslides, sinkholes, settlement, subsidence, active tectonics as well as structural deformation, all of which could be effected of climate change and human interaction. To magnify the impact of the project, the approach will be implemented in more than 400 sites on the UNESCO World Heritage List in geographical Europe. After the remote sensing investigation, detailed geological interpretation, hazard analysis, local-scale monitoring, advanced

CULTURAL IMPACT OF THE ORGANIZATIONAL VALUES IN THE ADOPTION OF PROJECT MANAGEMENT PRACTICES

Ariza-Aguilera, Dora A.

2015-12-01

Full Text Available Project management is a knowledge area that counts with the definition of best practices and methodologies, around the world. However, the use of these practices, is affected by social norms within an organization (Alavi, Kayworth & Leidner, 2005 and by the interpretation made by individuals, about the usefulness of these practices (Stare, 2012. This work seeks to establish the cultural effect of the values in the extent to which people adopt the project management practices in organizations. From the literature review, honesty, formalization, responsibility and justice were identified as values associated to behaviors that include the use of project management practices. A questionnaire was administered to a random sample of 55 companies located in Bogotá, Colombia, from various sectors of industry. Positive relationships between cultural values and the adoption of project management practices was evidenced. It was found that the extent, to which these practices are adopted, is a function of formalization. The theoretical contribution of this research is to provide empirical evidence of the relationship between cultural values and project management practices, since there are no studies about this relation. Its utility is to provide guidance to organizations on the need to promote the formalization as cultural value, to increase the use of project management practices. This integration lead to greater effectiveness (Rosenthal & Masarech, 2003.

Assessing local resources and culture before instituting quality improvement projects.

Science.gov (United States)

Hawkins, C Matthew

2014-12-01

The planning phases of quality improvement projects are commonly overlooked. Disorganized planning and implementation can escalate chaos, intensify resistance to change, and increase the likelihood of failure. Two important steps in the planning phase are (1) assessing local resources available to aid in the quality improvement project and (2) evaluating the culture in which the desired change is to be implemented. Assessing local resources includes identifying and engaging key stakeholders and evaluating if appropriate expertise is available for the scope of the project. This process also involves engaging informaticists and gathering available IT tools to plan and automate (to the extent possible) the data-gathering, analysis, and feedback steps. Culture in a department is influenced by the ability and willingness to manage resistance to change, build consensus, span boundaries between stakeholders, and become a learning organization. Allotting appropriate time to perform these preparatory steps will increase the odds of successfully performing a quality improvement project and implementing change.

Providing a controllable and definable three-dimensional (3D) microenvironment for chondrogenic differentiation of mesenchymal stem cells (MSCs) remains a great challenge for cartilage tissue engineering. In this work, poly(N-isopropylacrylamide) (PNIPAAm) polymers with the degrees of polymerization of 100 and 400 (NI100 and NI400) were prepared and the polymer solutions were introduced into the preprepared chitosan porous scaffolds (CS) to form hybrids (CSNI100 and CSNI400, respectively). SEM images indicated that the PNIPAAm gel partially occupied chitosan pores while the interconnected porous structure of chitosan was preserved. MSCs were incorporated within the hybrid and cell proliferation and chondrogenic differentiation were monitored. After 7-day incubation of the cell-laden constructs in a growth medium, the cell viability in CSNI100 and CSNI400 were 54 and 108% higher than that in CS alone, respectively. Glycosaminoglycan and total collagen contents increased 2.6- and 2.5-fold after 28-day culture of cell-laden CSNI400 in the chondrogenic medium. These results suggest that the hybrid structure composed of the chitosan porous scaffold and the well-defined PNIPAAm hydrogel, in particular CSNI400, is suitable for 3D stem cell culture and cartilage tissue engineering. © 2016 Wiley Periodicals, Inc.

Full Text Available The X-Culture project is an innovative modern form of experiential learning predominantly in International Management and International Business. Although experiential learning has some advantages, namely, developing cross-cultural competencies, cultural intelligence, intercultural communication and management skills, differences in personality or conditions also arise as a downside. X-Culture has been evolving throughout the years since 2010 when the original objective was to supplement the theoretical material and in-class teaching. Nowadays more than 4000 master, bachelor and MBA students, mostly of management and economics from more than 37 countries, take part in the project every semester. X-Culture is aimed at students of International Business college courses and training programs with the task of writing a business report or consulting propositions by offering business solutions for a hypothetical client.  This paper outlines the theoretical background of the X-culture project. It describes the evolution and practical and theoretical experience of this project since 2010.

Inhibition, Updating Working Memory, and Shifting Predict Reading Disability Symptoms in a Hybrid Model: Project KIDS.

Recent achievement research suggests that executive function (EF), a set of regulatory processes that control both thought and action necessary for goal-directed behavior, is related to typical and atypical reading performance. This project examines the relation of EF, as measured by its components, Inhibition, Updating Working Memory, and Shifting, with a hybrid model of reading disability (RD). Our sample included 420 children who participated in a broader intervention project when they were in KG-third grade (age M = 6.63 years, SD = 1.04 years, range = 4.79-10.40 years). At the time their EF was assessed, using a parent-report Behavior Rating Inventory of Executive Function (BRIEF), they had a mean age of 13.21 years ( SD = 1.54 years; range = 10.47-16.63 years). The hybrid model of RD was operationalized as a composite consisting of four symptoms, and set so that any child could have any one, any two, any three, any four, or none of the symptoms included in the hybrid model. The four symptoms include low word reading achievement, unexpected low word reading achievement, poorer reading comprehension compared to listening comprehension, and dual-discrepancy response-to-intervention, requiring both low achievement and low growth in word reading. The results of our multilevel ordinal logistic regression analyses showed a significant relation between all three components of EF (Inhibition, Updating Working Memory, and Shifting) and the hybrid model of RD, and that the strength of EF's predictive power for RD classification was the highest when RD was modeled as having at least one or more symptoms. Importantly, the chances of being classified as having RD increased as EF performance worsened and decreased as EF performance improved. The question of whether any one EF component would emerge as a superior predictor was also examined and results showed that Inhibition, Updating Working Memory, and Shifting were equally valuable as predictors of the hybrid model of RD

Energy level alignment at hybridized organic-metal interfaces from a GW projection approach

Science.gov (United States)

Chen, Yifeng; Tamblyn, Isaac; Quek, Su Ying

Energy level alignments at organic-metal interfaces are of profound importance in numerous (opto)electronic applications. Standard density functional theory (DFT) calculations generally give incorrect energy level alignments and missing long-range polarization effects. Previous efforts to address this problem using the many-electron GW method have focused on physisorbed systems where hybridization effects are insignificant. Here, we use state-of-the-art GW methods to predict the level alignment at the amine-Au interface, where molecular levels do hybridize with metallic states. This non-trivial hybridization implies that DFT result is a poor approximation to the quasiparticle states. However, we find that the self-energy operator is approximately diagonal in the molecular basis, allowing us to use a projection approach to predict the level alignments. Our results indicate that the metallic substrate reduces the HOMO-LUMO gap by 3.5 4.0 eV, depending on the molecular coverage/presence of Au adatoms. Our GW results are further compared with those of a simple image charge model that describes the level alignment in physisorbed systems.

Full Text Available Writing is considered to be the most demanding and difficult skill for many college students, since there are some steps to be followed such as prewriting, drafting, editing, revising and publishing. The interesting topic like culture including lifestyle, costume, and custom is necessary to be offered in Academic Writing class. Accordingly, this article aims to elaborate the application of a cultural project based learning to develop students’ ability in academic writing. This descriptive qualitative research was conducted in Academic Writing class consisting of 20 students of the fourth semester. The students were divided into some groups, each consisting of 4-5 people assigned to make a cultural project within 6 weeks, in the form of essay. Each member of the groups has to create his/ her own essay and then compile the essays to be a mini-journal. Therefore, one group has one mini-journal consisting of 4-5 essays. To check the content of mini-journal, the lecturer also asked the groups to present in front of the class to get some suggestions, feedback, or comments.

Full Text Available The infestation rate in Colossoma macropomum, hybrid tambacu (C. macropomum x Piaractus mesopotamicus and hybrid tambatinga (C. macropomum x Piaractus brachypomum with Perulernaea gamitanae Thatcher and Paredes, 1985 from two fish farms in Amapá State, Brazil was studied. Lernaeid parasites (n=2887 were collected mainly on the tongue and the mouth cavity and also on cartilage of gill arches and filaments. Inflammation and fibrous nodules were observed on the attachment sites of the parasites. The infestation rate varied according to the fish farm and host. The prevalence of P. gamitanae was of 100% in hosts from one fish farm and was lower in the other fish farm. Higher intensity of P. gamitanae occurred in hybrids tambacu and tambatinga, but despite the high prevalence its intensity was moderate. This is the first report on epidemiology of P. gamitanae in cultured fishes from Brazilian Amazonia, and the occurrence of this crustacean parasite in two new hosts, the hybrids tambacu and tambatinga.

This report describes a combined immunocytochemical and in situ hybridization procedure which allows visualization of cellular or viral antigens and viral RNA in the same cell. Cultures infected with visna or measles virus were fixed in periodate-lysine-paraformaldehyde-glutaraldehyde, stained by the avidin-biotin-peroxidase technique using antibodies to viral or cellular proteins and then incubated with radiolabeled specific DNA probes (in situ hybridization). This technique provides a new approach to the study of viral pathogenesis by: (1) identifying the types of cells which are infected in the host and (2) identifying points of blockade in the virus life cycle during persistent infections.

Claeyé, Frederik; Jackson, Terence

2011-01-01

The purpose of this paper is to report the findings of a broad-based study that initially investigated a possible gap in global inputs into the fight against HIV/AIDS and TB co-infection, and outputs in terms of results achieved. It is proposed that such a gap may be hypothesized to be due, at least in part, to inappropriate management regimes within the global health governance structure. The research does not simply question the effectiveness of the management of programs and projects, but rather the inappropriateness resulting from the lack of addressing cross-cultural issues. The factors facilitating or hampering project service delivery were examined, by looking at 12 case studies in Botswana and South Africa. These data were complemented with seven semi-structured interviews with donor organizations and NGOs, conducted in the North. Cultural interactions were investigated by using the concept of "interfaces". The results suggest that there is a disjuncture between the global and local level that affects project delivery. The main issues hampering project outcomes can be summarized as systemic, structural and cultural. The article's main contributions are both theoretical, looking at global project delivery from a cross-cultural management perspective, as well as to development praxis by highlighting the need to focus more critically on cross-cultural management issues within the global health governance structure, and indeed within international development as a whole.

Full Text Available Recent achievement research suggests that executive function (EF, a set of regulatory processes that control both thought and action necessary for goal-directed behavior, is related to typical and atypical reading performance. This project examines the relation of EF, as measured by its components, Inhibition, Updating Working Memory, and Shifting, with a hybrid model of reading disability (RD. Our sample included 420 children who participated in a broader intervention project when they were in KG-third grade (age M = 6.63 years, SD = 1.04 years, range = 4.79–10.40 years. At the time their EF was assessed, using a parent-report Behavior Rating Inventory of Executive Function (BRIEF, they had a mean age of 13.21 years (SD = 1.54 years; range = 10.47–16.63 years. The hybrid model of RD was operationalized as a composite consisting of four symptoms, and set so that any child could have any one, any two, any three, any four, or none of the symptoms included in the hybrid model. The four symptoms include low word reading achievement, unexpected low word reading achievement, poorer reading comprehension compared to listening comprehension, and dual-discrepancy response-to-intervention, requiring both low achievement and low growth in word reading. The results of our multilevel ordinal logistic regression analyses showed a significant relation between all three components of EF (Inhibition, Updating Working Memory, and Shifting and the hybrid model of RD, and that the strength of EF’s predictive power for RD classification was the highest when RD was modeled as having at least one or more symptoms. Importantly, the chances of being classified as having RD increased as EF performance worsened and decreased as EF performance improved. The question of whether any one EF component would emerge as a superior predictor was also examined and results showed that Inhibition, Updating Working Memory, and Shifting were equally valuable as predictors of the

The epistemic culture in an online citizen science project: Programs, antiprograms and epistemic subjects.

Kasperowski, Dick; Hillman, Thomas

2018-05-01

In the past decade, some areas of science have begun turning to masses of online volunteers through open calls for generating and classifying very large sets of data. The purpose of this study is to investigate the epistemic culture of a large-scale online citizen science project, the Galaxy Zoo, that turns to volunteers for the classification of images of galaxies. For this task, we chose to apply the concepts of programs and antiprograms to examine the 'essential tensions' that arise in relation to the mobilizing values of a citizen science project and the epistemic subjects and cultures that are enacted by its volunteers. Our premise is that these tensions reveal central features of the epistemic subjects and distributed cognition of epistemic cultures in these large-scale citizen science projects.

In this study, poplar tissue culture (hybrid black poplar, M1 genotype) was subjected to water stress influenced by polyethyleneglycol 6000 (100 and 200 mOsm PEG 6000). The aim of the research was to investigate the biochemical response of poplar tissue culture on water deficit regime. Antioxidant status was analyzed including antioxidant enzymes, superoxide-dismutase (SOD), catalase (CAT), guiacol-peroxidase (GPx), glutathione-peroxidase (GSH-Px), glutathione-reductase, reduced glutathione, total phenol content, Ferric reducing antioxidant power and DPPH radical antioxidant power. Polyphenol oxidase and phenylalanine-ammonium-lyase were determined as enzymatic markers of polyphenol metabolism. Among oxidative stress parameters lipid peroxidation, carbonyl-proteins, hydrogen-peroxide, reactive oxygen species, nitric-oxide and peroxynitrite were determined. Proline, proline-dehydrogenase and glycinebetaine were measured also as parameters of water stress. Cell viability is finally determined as a biological indicator of osmotic stress. It was found that water stress induced reactive oxygen and nitrogen species and lipid peroxidation in leaves of hybrid black poplar and reduced cell viability. Antioxidant enzymes including SOD, GPx, CAT and GSH-Px were induced but total phenol content and antioxidant capacity were reduced by PEG 6000 mediated osmotic stress. The highest biochemical response and adaptive reaction was the increase of proline and GB especially by 200 mOsm PEG. While long term molecular analysis will be necessary to fully address the poplar potentials for water stress adaptation, our results on hybrid black poplar suggest that glycine-betaine, proline and PDH enzyme might be the most important markers of poplar on water stress and that future efforts should be focused on these markers and strategies to enhance their concentration in poplar.

Diversity vs. Difference: A Critical Analysis of Hybridity and Cultural Identity Crisis in the Novels of Cheikh Hamidou Kane and Chinua Achebe

Directory of Open Access Journals (Sweden)

Alassane Abdoulaye DIA

2014-03-01

Full Text Available Hybridity has been one of the most recurrent themes of the African fiction during and after the colonial period. It is one of the complex issues of postcolonial Africa as it was difficult for many Négritude writers, such as Léopold Sédar Senghor, Aimé Césaire, and Frantz Fanon, to find a common ground on what colonization bequeathed to Africa. Hence, Senghor (1977 came up with the oxymoron of “colonization as a necessary evil”. However, to evaluate the advantages and disadvantages of colonization to Africans, in terms of impact, one should go further than expected to approve or dismantle Senghor’s position. The issues of cultural hybridity and identity crisis are still topical in African literature. Also, in the context of globalization, it is relevant to study the post-independence situation of African societies as represented by their early prominent and visionary writers such as Chinua Achebe from Nigeria and Cheikh Hamidou Kane from Senegal. Therefore, hybridity becomes a concern, through which writers address the dilemma of the African. They portray the intellectual who is entrapped in two different cultures and becomes alienated. The corpus of this article showcases this phenomenon through the characters of Obi Okonkwo in No Longer at Ease (1960 and Samba Diallo in Ambiguous Adventure (1962. Through a critical analysis and a post-colonial perspective, the article focuses on identity crisis, alongside the contentious debate over cultural diversity versus cultural difference, which is highly reflected in the novels investigated in the paper.

A new fluorescence in situ hybridization (FISH) method that uses peptide nucleic acid (PNA) probes for identification of Candida albicans directly from positive-blood-culture bottles in which yeast was observed by Gram staining (herein referred to as yeast-positive blood culture bottles) is described. The test (the C. albicans PNA FISH method) is based on a fluorescein-labeled PNA probe that targets C. albicans 26S rRNA. The PNA probe is added to smears made directly from the contents of the blood culture bottle and hybridized for 90 min at 55°C. Unhybridized PNA probe is removed by washing of the mixture (30 min), and the smears are examined by fluorescence microscopy. The specificity of the method was confirmed with 23 reference strains representing phylogenetically related yeast species and 148 clinical isolates covering the clinically most significant yeast species, including C. albicans (n = 72), C. dubliniensis (n = 58), C. glabrata (n = 5), C. krusei (n = 2), C. parapsilosis (n = 4), and C. tropicalis (n = 3). The performance of the C. albicans PNA FISH method as a diagnostic test was evaluated with 33 routine and 25 simulated yeast-positive blood culture bottles and showed 100% sensitivity and 100% specificity. It is concluded that this 2.5-h method for the definitive identification of C. albicans directly from yeast-positive blood culture bottles provides important information for optimal antifungal therapy and patient management.

A Hybrid MCDM Technique for Risk Management in Construction Projects

Directory of Open Access Journals (Sweden)

Kajal Chatterjee

2018-02-01

Full Text Available Multi-stakeholder based construction projects are subject to potential risk factors due to dynamic business environment and stakeholders’ lack of knowledge. When solving project management tasks, it is necessary to quantify the main risk indicators of the projects. Managing these requires suitable risk mitigation strategies to evaluate and analyse their severity. The existence of information asymmetry also causes difficulties with achieving Pareto efficiency. Hence, to ensure balanced satisfaction of all participants, risk evaluation of these projects can be considered as an important part of the multi-criteria decision-making (MCDM process. In real-life problems, evaluation of project risks is often uncertain and even incomplete, and the prevailing methodologies fail to handle such situations. To address the problem, this paper extends the analytical network process (ANP methodology in the D numbers domain to handle three types of ambiguous information’s, viz. complete, uncertain, and incomplete, and assesses the weight of risk criteria. The D numbers based approach overcomes the deficiencies of the exclusiveness hypothesis and completeness constraint of Dempster–Shafer (D–S theory. Here, preference ratings of the decision matrix for each decision-maker are determined using a D numbers extended consistent fuzzy preference relation (D-CFPR. An extended multi-attributive border approximation area comparison (MABAC method in D numbers is then developed to rank and select the best alternative risk response strategy. Finally, an illustrative example from construction sector is presented to check the feasibility of the proposed approach. For checking the reliability of alternative ranking, a comparative analysis is performed with different MCDM approaches in D numbers domain. Based on different criteria weights, a sensitivity analysis of obtained ranking of the hybrid D-ANP-MABAC model is performed to verify the robustness of the proposed

Hybrid renewable energy systems is one of the most promising application of renewable energy technologies in remote areas, where the cost of grid extension is prohibitive and the price of fossil fuels increase drastically with the remoteness of the location. Applications of hybrid systems range from small power supplies for remote households providing electricity for lighting or water pumping and water supply to village electrification for remote communities. The strategic objective of the HYRESS project is to remove the knowledge barriers against the installation of Renewable Energy Systems and creation of micro grids. In order to fulfill this objective, three different modular hybrid systems with the generating technologies connected to the AC side were designet, installed and evaluated in three selected remote sites far away from the grid in Egypt, Morocco and Tunisia. This paper describes the hybrid system installed in Egypt as a case study and presents first operation results. (orig.)

Foot, Kirsten

2015-01-01

The HUSK projects catalyzed innovation in the practices of providing social services that could yield useful insights both within and outside of Norway if analyzed in these two ways: (a) retrospective analysis of the development of individual HUSK projects in light of their cultural-historical contexts, and (b) comparative analysis of the efforts to advance multi-sector collaboration in some of the HUSK projects. Such analyses require a practice-based research approach that takes into account culture and history. In this article the author explains how cultural-historical activity theory provides such an approach, illustrated via several HUSK cases. The author suggests five questions for future analyses of the HUSK projects and argues that insights gleaned from such analyses could contribute significantly to research on-and the provision of-social services.

2011-05-01

Full Text Available In the summer of 2008, immediately prior to the Beijing Olympics, a massive green tide of the genus Ulva covered the Qingdao coast of the Yellow Sea in China. Based on molecular analyses using the nuclear encoded rDNA internal transcribed spacer (ITS region, the Qingdao strains dominating the green tide were reported to be included in a single phylogenetic clade, currently regarded as a single species. On the other hand, our detailed phylogenetic analyses of the clade, using a higher resolution DNA marker, suggested that two genetically separate entities could be included within the clade. However, speciation within the Ulva clade has not yet been examined. We examined the occurrence of an intricate speciation within the clade, including the Qingdao strains, via combined studies of culture, hybridization and phylogenetic analysis. The two entities separated by our phylogenetic analyses of the clade were simply distinguished as U. linza and U. prolifera morphologically by the absence or presence of branches in cultured thalli. The inclusion of sexual strains and several asexual strains were found in each taxon. Hybridizations among the sexual strains also supported the separation by a partial gamete incompatibility. The sexually reproducing Qingdao strains crossed with U. prolifera without any reproductive boundary, but a complete reproductive isolation to U. linza occurred by gamete incompatibility. The results demonstrate that the U. prolifera group includes two types of sexual strains distinguishable by crossing affinity to U. linza. Species identification within the Ulva clade requires high resolution DNA markers and/or hybridization experiments and is not possible by reliance on the ITS markers alone.

Collaboration and Crisis in Mega Projects: A Study in Cross Corporate Culture Conflict and its Resolution

Directory of Open Access Journals (Sweden)

Karen Smits

2017-06-01

Full Text Available Projects typically involve multiple partners coming together to form a temporary project organization that manages project execution. Partners begin their relationship with soaring aspirations to collaborate but as they move through the project’s various phases and they experience friction, especially those related to cultural clashes, their noble aspirations succumb to creeping, if not full blown, crisis. This, in turn, creates lost relationality and compromised execution. Thus, the question: How can project partners manage the integration of differing corporate cultures and work processes to produce the most effective and efficient outcomes?  Using the mega project of the Panama Canal Expansion Program, the authors explore how a multicultural project organization moved from dysfunctional relationality to synergistic, self-reinforcing, collaboration. A “Collabyrinth” (Smits, 2013 model explores how participants learned to collaborate in a holding environment saturated with layers of complex cultural difference.  The Collabyrinth is composed of six comingling elements: (1 Conflicting Conditions, (2 Submarining, (3 Seeking Consent, (4 Storytelling, (5 Crafting Reciprocal Relations, (6 Synergizing. Certain aspects of crisis management are employed to explain intra-collabyrinth dynamics. Those aspects are: (1 Coming of the Forerunners, (2 Acuteness in the Now, (3 Resolution Seeking, and (4 Constructing Relationality. Specific examples of the collabyrinth journey are provided and recommendations are made to harness the positive power of cross-corporate culture collaboration.

Safety culture and subcontractor network governance in a complex safety critical project

International Nuclear Information System (INIS)

Oedewald, Pia; Gotcheva, Nadezhda

2015-01-01

In safety critical industries many activities are currently carried out by subcontractor networks. Nevertheless, there are few studies where the core dimensions of resilience would have been studied in safety critical network activities. This paper claims that engineering resilience into a system is largely about steering the development of culture of the system towards better ability to anticipate, monitor, respond and learn. Thus, safety culture literature has relevance in resilience engineering field. This paper analyzes practical and theoretical challenges in applying the concept of safety culture in a complex, dynamic network of subcontractors involved in the construction of a new nuclear power plant in Finland, Olkiluoto 3. The concept of safety culture is in focus since it is widely used in nuclear industry and bridges the scientific and practical interests. This paper approaches subcontractor networks as complex systems. However, the management model of the Olkiluoto 3 project is to a large degree a traditional top-down hierarchy, which creates a mismatch between the management approach and the characteristics of the system to be managed. New insights were drawn from network governance studies. - Highlights: • We studied a relevant topical subject safety culture in nuclear new build project. • We integrated safety science challenges and network governance studies. • We produced practicable insights in managing safety of subcontractor networks

Early 2010 saw a signi cant change in adversarial techniques aimed at network intrusion: a shift from malware delivered via email attachments toward the use of hidden, embedded hyperlinks to initiate sequences of downloads and interactions with web sites and network servers containing malicious software. Enterprise security groups were well poised and experienced in defending the former attacks, but the new types of attacks were larger in number, more challenging to detect, dynamic in nature, and required the development of new technologies and analytic capabilities. The Hybrid LDRD project was aimed at delivering new capabilities in large-scale data modeling and analysis to enterprise security operators and analysts and understanding the challenges of detection and prevention of emerging cybersecurity threats. Leveraging previous LDRD research e orts and capabilities in large-scale relational data analysis, large-scale discrete data analysis and visualization, and streaming data analysis, new modeling and analysis capabilities were quickly brought to bear on the problems in email phishing and spear phishing attacks in the Sandia enterprise security operational groups at the onset of the Hybrid project. As part of this project, a software development and deployment framework was created within the security analyst work ow tool sets to facilitate the delivery and testing of new capabilities as they became available, and machine learning algorithms were developed to address the challenge of dynamic threats. Furthermore, researchers from the Hybrid project were embedded in the security analyst groups for almost a full year, engaged in daily operational activities and routines, creating an atmosphere of trust and collaboration between the researchers and security personnel. The Hybrid project has altered the way that research ideas can be incorporated into the production environments of Sandias enterprise security groups, reducing time to deployment from months and

Prevention of demoralization in prolonged bicultural conflict and interaction: the role of cultural receptors II - genesis of hybridization.

Science.gov (United States)

de Figueiredo, John M

2013-08-01

The objective of this article is to show that bicultural hybridization for the prevention of demoralization is anchored on the discovery of certain thematic areas (cultural receptors) in which social roles or cultural mandates are missing, unclear, ambiguous or congruent. The specific setting is the history of Goa, a former Portuguese territory on the western coast of India. Both published and unpublished sources of information were studied. Education, occupation and income, the three dimensions of social class, were less dominant than other aspects of the Hindu caste system, such as birth into a group viewed as a caste, observance of marriage circles, regulations of kinship and inheritance, and identification with a location. These other aspects were preserved as much as possible. The result was the conversion of the caste system into a system more akin to social class. Other examples of cultural receptors were found. A key step in the adaptation to acculturative stress is the discovery of cultural receptors in both cultures and the development of meaningful interconnections among those receptors. Psychotherapy attempts the restoration of morale. To be effective, therapists should consider the hierarchical organization of symbols and sentiments in the patient's culture.

There has been continuous progress in the development for biomedical engineering systems of hybrid muscle generated by combining skeletal muscle and artificial structure. The main factor affecting the actuation performance of hybrid muscle relies on the compatibility between living cells and their muscle scaffolds during cell culture. Here, we developed a hybrid muscle powered by C2C12 skeletal muscle cells based on the functionalized multi-walled carbon nanotubes (MWCNT) sheets coated with poly(3,4-ethylenedioxythiophene) (PEDOT) to achieve biomimetic actuation. This hydrophilic hybrid muscle is physically durable in solution and responds to electric field stimulation with flexible movement. Furthermore, the biomimetic actuation when controlled by electric field stimulation results in movement similar to that of the hornworm by patterned cell culture method. The contraction and relaxation behavior of the PEDOT/MWCNT-based hybrid muscle is similar to that of the single myotube movement, but has faster relaxation kinetics because of the shape-maintenance properties of the freestanding PEDOT/MWCNT sheets in solution. Our development provides the potential possibility for substantial innovation in the next generation of cell-based biohybrid microsystems.

Hybrid hybridomas are obtained by fusion of two cells, each producing its own antibody. Several authors have reported the construction of murine hybrid hybridomas with the aim to obtain bispecific monoclonal antibodies. The authors have investigated, in a model system, the feasibility of constructing a human hybrid hybridoma. They fused two monoclonal cell lines: an ouabain-sensitive and azaserine/hypoxanthine-resistant Epstein-Barr virus-transformed human cell line that produces an IgG1kappa antibody directed against tetanus toxiod and an azaserine/hypoxanthine-sensitive and ouabain-resistant human-mouse xenohybrid cell line that produces a human IgG1lambda antibody directed against hepatitis-B surface antigen. Hybrid hybridoma cells were selected in culture medium containing azaserine/hypoxanthine and ouabain. The hybrid nature of the secreted antibodies was analyzed by means of two antigen-specific immunoassay. The results show that it is possible, with the combined use of transformation and xenohybridization techniques, to construct human hybrid hybridomas that produce bispecific antibodies. Bispecific antibodies activity was measured by means of two radioimmunoassays.

The researchers developed the International Collaborative Project on Cultural Competence (ICPCC to help students understand the impact of cultural context on client care. Entry-level MOT students from a university in the US (N = 18 collaborated with BOT students (N = 4 and advanced MOT students (N = 9 from two universities in India using an online course management system WebCT. The study explored the impact of the ICPCC on OT students’ cultural competence and discusses students’ perceptions of culture on the OT process. The Inventory for Assessing the Process of Cultural Competence Among Health Care Professionals Revised© measured students’ cultural competence at baseline and immediately after participation in the ICPCC. Qualitative data was collected using a Self-Reflection Form. There was an increase in the cultural competence scores among all three groups of students after participating in the ICPCC at p value < .05. Three themes emerged from the qualitative data analysis: meaning of the term culture, impact of cultural on client- centered practice, and impact of cultural on OT outcomes. OT students recognized the role that cultural differences play in OT evaluation and intervention.

Full Text Available Changing demographics and an emphasis on competency-based social work education call for innovative approaches to the delivery of curricular content. In an effort to introduce BSW students to the socio-political issues facing the local Latino immigrant community, a service-learning project was developed in collaboration with the Spanish Language Department and a local middle school. An analysis of outcomes from social work student evaluations showed that students engaged with the community and issues in new and unexpected ways. Through their engagement in a cross-cultural group project, students developed greater cultural competency, honed their group practice skills in an unfamiliar context, provided a needed service to the community, and raised their awareness about the working conditions of new immigrants as part of a developing framework for social action. Details and implications of the project as a means to build student competencies are described.

The Cultural Challenges of Managing Global Project Teams: A Study of Brazilian Multinationals

Directory of Open Access Journals (Sweden)

Ivete Rodrigues

2013-04-01

Full Text Available The internationalization of Brazilian companies brings a new reality: the need for implementation of global projects that bring, in turn, the challenge of managing multicultural teams. Since this is a recent phenomenon with little theoretical development, this study sought to understand the relationships between cultural characteristics and management teams of global projects in Brazilian multinationals. To carry this discussion forward, we studied six cases of Brazilian multinational companies, with the aim of deepening the understanding of the management of global teams, involving the planning, deployment, development and management of human resources. Among the projects studied, it was found that there is very little concern with the specific issue of multiculturalism and little inter-cultural incentive to the development of team members, which ends up hindering the construction of a global mindset, important for the Brazilian multinational companies to perform successfully abroad. Faced with this situation, each of the managerial processes mentioned were presented with a number of actions to be undertaken by the project manager in three different dimensions: the project itself, the organization and the global environment. The work contributes, thus, to enable Brazilian multinational companies to manage their global teams in order to maximize the advantages of global teams, such as increased creativity and innovative capacity, but avoid the problems that multiculturalism can bring, ranging from conflicts between people to project failure.

Electric and Hybrid Vehicle System Research and Development Project: Hybrid Vehicle Potential Assessment. Volume VI. Cost analysis

Energy Technology Data Exchange (ETDEWEB)

Hardy, K.S.

1979-09-30

The purpose of the cost analysis is to determine the economic feasibility of a variety of hybrid vehicles with respect to conventional vehicles specifically designed for the same duty cycle defined by the mission analysis. Several different hybrid configurations including parallel, parallel-flywheel, and series vehicles were evaluated. The ramifications of incorporating examples of advanced batteries, these being the advanced lead-acid, nickel-zinc, and sodium sulfur were also investigated. Vehicles were specifically designed with these batteries and for the driving cycles specified by the mission. Simulated operation on the missions yielded the energy consumption (petroleum and/or electricity) over the driving cycles. It was concluded that: in the event that gasoline prices reach $2.50 to $3.00/gal, hybrid vehicles in many applications will become economically competitive with conventional vehicles without subsidization; in some commercial applications hybrid vehicles could be economically competitive, when the gasoline price ranges from $1.20 to $1.50/gal. The cost per kWh per cycle of the advanced batteries is much more important economically than the specific energy; the series hybrid vehicles were found to be more expensive in comparison to the parallel or parallel-flywheel hybrids when designed as passenger vehicles; and hybrid vehicles designed for private use could become economically competitive and displace up to 50% of the fuel normally used on that mission if subsidies of $500 to $2000 were supplied to the owner/operator.

Full Text Available This paper constitutes a reflective account of inclusive approaches in two children’s music projects, both aiming to foster group creativityalongside cross-cultural awareness and understanding. The first of these projects involved sharing songs composed by children and youngpeople from a special needs school in Mostar, Bosnia-Herzegovina, with a primary school choir in Edinburgh, Scotland. The second project, inSarajevo, Bosnia-Herzegovina, focused on group song-writing and performance involving three groups of children from ethnically separated schools, alongside a choir from a school for children with visual impairments. On reflection, we discuss cross-cultural musical collaboration as an effective means of bringing children togetheracross social and cultural divides in order to share new experiences while building respect for differences. We hope projects such as these may represent the first step towards the ultimate goal of encouraging and nurturing more inclusive friendships between children who might not otherwise have opportunities to interact with each other.

Oliveira, Kenneth; Procop, Gary W.; Wilson, Deborah; Coull, James; Stender, Henrik

2002-01-01

A new fluorescence in situ hybridization (FISH) method with peptide nucleic acid (PNA) probes for identification of Staphylococcus aureus directly from positive blood culture bottles that contain gram-positive cocci in clusters (GPCC) is described. The test (the S. aureus PNA FISH assay) is based on a fluorescein-labeled PNA probe that targets a species-specific sequence of the 16S rRNA of S. aureus. Evaluations with 17 reference strains and 48 clinical isolates, including methicillin-resistant and methicillin-susceptible S. aureus species, coagulase-negative Staphylococcus species, and other clinically relevant and phylogenetically related bacteria and yeast species, showed that the assay had 100% sensitivity and 96% specificity. Clinical trials with 87 blood cultures positive for GPCC correctly identified 36 of 37 (97%) of the S. aureus-positive cultures identified by standard microbiological methods. The positive and negative predictive values were 100 and 98%, respectively. It is concluded that this rapid method (2.5 h) for identification of S. aureus directly from blood culture bottles that contain GPCC offers important information for optimal antibiotic therapy.

A system model of the mirror hybrid reactor has been developed. The major components of the model include (1) the reactor description, (2) a capital cost analysis, (3) various fuel management schemes, and (4) an economic analysis that includes the hybrid plus its associated fission burner reactors. The results presented describe the optimization of the mirror hybrid reactor, the objective being to minimize the cost of electricity from the hybrid fission-burner reactor complex. We have examined hybrid reactors with two types of blankets, one containing natural uranium, the other thorium. The major difference between the two optimized reactors is that the uranium hybrid is a significant net electrical power producer, whereas the thorium hybrid just about breaks even on electrical power. Our projected costs for fissile fuel production are approximately 50 $/g for 239 Pu and approximately 125 $/g for 233 U

Highlights: ► Culture belief is integrated into multi-objective differential evolution. ► Chaotic sequence is imported to improve evolutionary population diversity. ► The priority of convergence rate is proved in solving hydrothermal problem. ► The results show the quality and potential of proposed algorithm. - Abstract: A culture belief based multi-objective hybrid differential evolution (CB-MOHDE) is presented to solve short term hydrothermal optimal scheduling with economic emission (SHOSEE) problem. This problem is formulated for compromising thermal cost and emission issue while considering its complicated non-linear constraints with non-smooth and non-convex characteristics. The proposed algorithm integrates a modified multi-objective differential evolutionary algorithm into the computation model of culture algorithm (CA) as well as some communication protocols between population space and belief space, three knowledge structures in belief space are redefined according to these problem-solving characteristics, and in the differential evolution a chaotic factor is embedded into mutation operator for avoiding the premature convergence by enlarging the search scale when the search trajectory reaches local optima. Furthermore, a new heuristic constraint-handling technique is utilized to handle those complex equality and inequality constraints of SHOSEE problem. After the application on hydrothermal scheduling system, the efficiency and stability of the proposed CB-MOHDE is verified by its more desirable results in comparison to other method established recently, and the simulation results also reveal that CB-MOHDE can be a promising alternative for solving SHOSEE.

Using Tradtional Ecological Knowledge to Protect Wetlands: the Swinomish Tribe's Wetland Cultural Assessment Project

Science.gov (United States)

Mitchell, T.

2017-12-01

"Traditional" wetland physical assessment modules do not adequately identify Tribal cultural values of wetlands and thus wetlands may not be adequately protected for cultural uses. This Swinomish Wetlands Cultural Assessment Project has developed a cultural resource scoring module that can be incorporated into wetland assessments to better inform wetland protections. Local native knowledge was gathered about the traditional uses of 99 native wetland plant species. A cultural scoring matrix was developed based on the presence of traditionally used plants in several use categories including: construction, ceremonial, subsistence, medicinal, common use, plant rarity, and place of value for each wetland. The combined score of the cultural and physcial modules provides an overall wetland score that relates to proscribed buffer protection widths. With this local native knowledge incorporated into wetland assessments, we are protecting and preserving Swinomish Reservation wetlands for both cultural uses and ecological functionality through the Tribe's wetland protection law.

Culture plays a crucial role in our lives. Depending on our cultural background, we judge on and react to everything that we encounter. Subtle differences in behavior can lead to misunderstandings or even culture shock. In a similar manner, virtual characters can be declined by certain user groups when showing culturally inappropriate behavior. But how can social aspects such as culture be integrated into the behavioral models of virtual characters Birgit Endrass addresses this question by carrying out a hybrid approach that is based on theoretical background from the social sciences as well a

A Hybrid Approach to Protect Palmprint Templates

Directory of Open Access Journals (Sweden)

Hailun Liu

2014-01-01

Full Text Available Biometric template protection is indispensable to protect personal privacy in large-scale deployment of biometric systems. Accuracy, changeability, and security are three critical requirements for template protection algorithms. However, existing template protection algorithms cannot satisfy all these requirements well. In this paper, we propose a hybrid approach that combines random projection and fuzzy vault to improve the performances at these three points. Heterogeneous space is designed for combining random projection and fuzzy vault properly in the hybrid scheme. New chaff point generation method is also proposed to enhance the security of the heterogeneous vault. Theoretical analyses of proposed hybrid approach in terms of accuracy, changeability, and security are given in this paper. Palmprint database based experimental results well support the theoretical analyses and demonstrate the effectiveness of proposed hybrid approach.

Principle, function, experiences, hybrid chilled ceilings; Prinzip, Funktion, Erfahrungen. Hybrid-Kuehldecken

Hybrid chilled ceilings combine a radiation chilled ceiling with thermal activations of a concrete ceiling. The activation permits the utilization of alternative and/or small cold generators for the efficient night cooling. The traditional chilled ceiling grants a speedy reaction to load variations as well as a reduction of the reverberation periods. In addition, the combination supplies a draught-free insertion of air. Beside established solutions, MWH Barcol-Air (Staefa, Switzerland) also offers project-specific hybrid chilled ceilings.

Linear equations and rap battles: how students in a wired classroom utilized the computer as a resource to coordinate personal and mathematical positional identities in hybrid spaces

Langer-Osuna, Jennifer

2015-03-01

This paper draws on the constructs of hybridity, figured worlds, and cultural capital to examine how a group of African-American students in a technology-driven, project-based algebra classroom utilized the computer as a resource to coordinate personal and mathematical positional identities during group work. Analyses of several vignettes of small group dynamics highlight how hybridity was established as the students engaged in multiple on-task and off-task computer-based activities, each of which drew on different lived experiences and forms of cultural capital. The paper ends with a discussion on how classrooms that make use of student-led collaborative work, and where students are afforded autonomy, have the potential to support the academic engagement of students from historically marginalized communities.

Full Text Available EXTENDED ABSTRACT:DEDI stands for the Digital Encyclopaedia of Natural and Cultural Heritage in Slovenia which was a result of two prototype research and development projects DEDI and DEDI II in the period between 2008 and 2010. The two projects were co-financed by the Ministry of Higher Education, Science and Technology and the European Regional Development Fund in the frame of research and development projects e-content and e-services. DEDI is the first attempt of multimediarich digital representation of Slovenian natural and cultural heritage on a common web site offering verifiable, qualitative and complex content to a wide range of general public. Digital content (text, video records, audio records, photographs is enriched by 2-dimensional and/or 3-dimensional visualisation of geographical data or even by 4-dimensional models with time component. 4D models combine 3D models with the time dimension. Thus it is possible to simulate the past, the current and the future condition of natural and cultural heritage objects, their changes, growth, deterioration or oscillation. 3D and 4D models are more explanatory, plastic and attractive to the unprofessional public thus increasing the interest in the digital encyclopaedia. Technological solutions for the project were developed by the consortium partners in the field of web technologies who succeeded to locate all immovable natural and cultural heritage objects. The Google Maps web platform is normally used for 2D representations but it is often too complex to represent a large amount of data. In order to meet the needs of the digital encyclopaedia data need to be structured and linked which is one of the main advantages of Geopedia, an interactive atlas which enables active user participation in adding and editing information on Slovenia. A 3D visualisation tool Gaea+ is used for real time visualisation of 3D models offering user-friendly presentation of any geospatial information and an

Fluorescence in situ hybridization (FISH) has been shown to be useful for the detection of Candida and Cryptococcus species in blood culture materials. FISH procedures for the detection of Histoplasma capsulatum var. capsulatum have not been reported so far. This study describes the development and evaluation of fluorescently labeled rRNA-targeting FISH probes to detect and identify H. capsulatum in blood cultures. All three analyzed H. capsulatum reference strains and clinical isolates showed positive signals with the newly designed specific oligonucleotide probes for H. capsulatum, whereas negative reactions were observed for all three nontarget yeast species and the two nontarget bacteria. The assay was also successfully applied for detections of H. capsulatum cells in pre-incubated blood culture samples of patients with clinical suspicion of histoplasmosis (n = 33). The described FISH-based assay was shown to be easy to apply, sensitive, and specific (compared to polymerase chain reaction) for the detection and identification of H. capsulatum in this proof-of-principle analysis. Larger multicentric assessments are recommended for a thorough diagnostic evaluation of the procedure. © The Author 2014.

Coca-colonization and hybridization of diets among the Tz'utujil Maya.

Science.gov (United States)

Nagata, Jason M; Barg, Frances K; Valeggia, Claudia R; Bream, Kent D W

2011-01-01

Biomedical health professionals express increasing concern that rising consumption of soft drinks and processed foods in Mayan and Latin American eating patterns may lead to detrimental nutritional and health consequences. Scholars debate whether the pervading presence of Coca-Cola and Pepsi in developing countries represents "Coca-Colonization," synonymous with cultural imperialism, or cultural hybridization. Using mixed qualitative and quantitative research methods, including participant observation and semi-structured interviews, this study explores the development of Coca-Colonization and cultural hybridization among the Tz'utujil Maya of Santiago Atitlán, Guatemala. By specifically examining biomedical perspectives, cycles of conquest, the political economy, religion, celebrations, and the physical environment through the lens of soft drinks, this study finds that Coca-Colonization and cultural hybridization are complementary rather than mutually exclusive processes that contribute to dietary transitions, economic development, and differential health beliefs related to soft drink consumption.

The aim of this pilot study was to assess if array comparative genomic hybridization (aCGH), non-invasive preimplantation genetic screening (PGS) on blastocyst culture media is feasible. Therefore, aCGH analysis was carried out on 22 spent blastocyst culture media samples after polar body PGS because of advanced maternal age. All oocytes were fertilized by intracytoplasmic sperm injection and all embryos underwent assisted hatching. Concordance of polar body analysis and culture media genetic results was assessed. Thirteen out of 18 samples (72.2%) revealed general concordance of ploidy status (euploid or aneuploid). At least one chromosomal aberration was found concordant in 10 out of 15 embryos found to be aneuploid by both polar body and culture media analysis. Overall, 17 out of 35 (48.6%) single chromosomal aneuploidies were concordant between the culture media and polar body analysis. By analysing negative controls (oocytes with fertilization failure), notable maternal contamination was observed. Therefore, non-invasive PGS could serve as a second matrix after polar body or cleavage stage PGS; however, in euploid results, maternal contamination needs to be considered and results interpreted with caution.

Developing reliable three-dimensional (3D) cell culture systems that can mimic native tumor microenvironments is necessary for investigating the mechanism of hepatocellular carcinoma (HCC) metastasis and screen therapeutic drugs. In the present study, we developed decellularized liver matrix-alginate (DLM-ALG) hybrid gel beads. DLM powder was prepared by optimized decellularization methods and liquid nitrogen grinding. DLM-ALG beads were generated by dropping alginate solution containing DLM powder into a gelling bath. DLM powder concentration in alginate solution was ≤1% (w/v) and had no effect on the sphericity and mechanical stability of the beads. In addition, HCCLM3 cells cultured in 1% (w/v) DLM-ALG beads presented gradually enhanced viability during in vitro culture. The protein expression of urokinase plasminogen activator system and activity of matrix metalloproteinases (MMPs) of HCCLM3 cells, including MMP2 and MMP9, were more significantly promoted in DLM-ALG beads compared with that in conventional ALG beads without DLM powder. Moreover, the dose-dependent increase in HCCLM3 cell MMP activities was observed along with the DLM powder concentration in 0.5% and 1% DLM-ALG groups. Therefore, DLM-ALG beads might serve as a novel 3D culture system for exploring the mechanisms of HCC metastasis and screening therapeutic drugs. Copyright © 2017 Elsevier B.V. All rights reserved.

(D,T) Driven thorium hybrid blankets

Al-Kusayer, T.A.; Khan, S.; Sahin, S.

1983-01-01

Recently, a project has started, with the aim to establish the neutronic performance and the basic design of an experimental fusionfission (hybrid) reactor facility, called AYMAN, in cylinderical geometry. The fusion reactor will have to be simulated by a (D,T) neutron generator. Fissile and fertile fuel will have to surround the neutron generator as a cylinderical blanket to simulate the boundary conditions of the hybrid blanket in a proper way. This geometry is consistent with Tandem Mirror Hybrid Blanket design and with most of the ICF blanket designs. A similar experimental installation will become operational around 1984 at the Swiss Federal Institute of Technology in Lausanne, Switzerland known under the project LOTUS. Due to the limited dimensions of the experimental cavity of the LOTUS-hybrid reactor, the LOTUS blankets have to be designed in plane geometry. Also, the bulky form of the Haefely neutron generator of the LOTUS facility obliges one to design a blanket in the plane geometry. This results in a vacuum left boundary conditions for the LOTUS blanket. The importance of a reflecting left boundary condition on the overall neutronic performance of a hybrid blanket has been analyzed in previous work in detail

Interspecific somatic hybridization between lettuce (Lactuca sativa) and wild species L. virosa.

Science.gov (United States)

Matsumoto, E

1991-02-01

Somatic hybrids between cultivated lettuce (Lactuca sativa) and a wild species L. virosa were produced by protoplast electrofusion. Hybrid selection was based on inactivation of L. sativa with 20mM iodoacetamide for 15 min, and the inability of L. virosa protoplasts to divide in the culture conditions used. Protoplasts were cultured in agarose beads in a revised MS media. In all 71 calli were formed and 21 of them differentiated shoots on LS medium containing 0.1mg/l NAA and 0.2mg/l BA. Most regenerated plants exhibited intermediate morphology. These plants were confirmed as hybrids by isoenzyme analysis. The majority of somatic hybrids had 2n=4x=36 chromosomes, and had more vigorous growth than either parent. Hybrids had normal flower morphology, but all were sterile.

Hydraulic Hybrid Parcel Delivery Truck Deployment, Testing & Demonstration

Energy Technology Data Exchange (ETDEWEB)

Gallo, Jean-Baptiste [Calstart Incorporated, Pasadena, CA (United States)

2014-03-07

Although hydraulic hybrid systems have shown promise over the last few years, commercial deployment of these systems has primarily been limited to Class 8 refuse trucks. In 2005, the Hybrid Truck Users Forum initiated the Parcel Delivery Working Group including the largest parcel delivery fleets in North America. The goal of the working group was to evaluate and accelerate commercialization of hydraulic hybrid technology for parcel delivery vehicles. FedEx Ground, Purolator and United Parcel Service (UPS) took delivery of the world’s first commercially available hydraulic hybrid parcel delivery trucks in early 2012. The vehicle chassis includes a Parker Hannifin hydraulic hybrid drive system, integrated and assembled by Freightliner Custom Chassis Corp., with a body installed by Morgan Olson. With funding from the U.S. Department of Energy, CALSTART and its project partners assessed the performance, reliability, maintainability and fleet acceptance of three pre-production Class 6 hydraulic hybrid parcel delivery vehicles using information and data from in-use data collection and on-road testing. This document reports on the deployment of these vehicles operated by FedEx Ground, Purolator and UPS. The results presented provide a comprehensive overview of the performance of commercial hydraulic hybrid vehicles in parcel delivery applications. This project also informs fleets and manufacturers on the overall performance of hydraulic hybrid vehicles, provides insights on how the technology can be both improved and more effectively used. The key findings and recommendations of this project fall into four major categories: -Performance, -Fleet deployment, -Maintenance, -Business case. Hydraulic hybrid technology is relatively new to the market, as commercial vehicles have been introduced only in the past few years in refuse and parcel delivery applications. Successful demonstration could pave the way for additional purchases of hydraulic hybrid vehicles throughout the

The marvels of modern science often fail to engage indigenous students, as the content and instructional style are usually rooted in the Western experience. This 3 year project, funded by the US Dept. of Education for the Education of Native Hawaiians, offers a curriculum that teaches science through (rather than just about) Native Hawaiian culture. The curriculum focuses on the interdependence of natural resources in our ahupuaa, or watersheds, and helps students strengthen their sense of place and self to malama i ka aina, to care for the land. Further, the curriculum is designed to: engage students in scientific study with relevant, interesting content and activities; improve student achievement of state department of education standards; increase student knowledge and skills in science, math and language arts; respond to the learning needs of Native Hawaiian and/or at-risk students. The project will be presented by a curriculum writer who created and adapted more than a year's worth of materials by teaming with kupuna (respected elders), local cultural experts and role models, educators (new, veteran, Hawaiian, non-Hawaiian, mainland, general and special education teachers), and professionals at the Center on Disability Studies at the University of Hawaii and ALU LIKE, Inc, a non-profit organization to assist Native Hawaiians. The materials created thus far are available for viewing at: www.scihi.hawaii.edu The curriculum, designed for grades 8-11 science classes, can be used to teach a year-long course, a unit, or single lesson related to astronomy, biology, botany, chemistry, geology, oceanography, physical and environmental sciences. This project is in its final year of field testing, polishing and dissemination, and therefore this session will encourage idea sharing, as does our copyright free Web site.

A retrospective critic Re-Debate on Stakeholders’ resistance checklist in software project management within multi-cultural, multi-ethnical and cosmopolitan society context: The Malaysian experience

Full Text Available Risks stemming from software projects were extensively studied. However, software project risk management has rarely researched organizational risks within multi-cultural and multi-ethnical atmospheres. The fact of the matter is that problems occur when the stakeholders’ cultural and ethnical aspects are not addressed, especially in multi-cultural, multi-ethnical, and cosmopolitan society such as Malaysia. To avoid analyzing something that has already been studied in detail, this study conducted based on in-depth literature review considering key word search in subject-specific databases. Journal articles published in reputed journals were reviewed. By employing Rumelt’s resistance to change checklist and culture gap tool source, this paper develops an organizational risk framework considering cross-cultural and cross-ethnical critical factors in order to show how can risks be better comprehended and managed. The significance of bio-cultural dimensions was scrutinized as vital criteria which should be considered in international project sphere, so that, not only the odds of project success would be increased but also the risks can be mitigated significantly. A review of the risk management process, Rumelt’s Checklist, cultural issues in international project environment allows a better understanding of the importance of cultural dimensions in project spheres.

Ornamental marine species (`OMS') provide valuable income for developing nations in the Indo-Pacific Coral Triangle, from which most of the specimens are exported. OMS culture can help diversify livelihoods in the region, in support of management and conservation efforts to reduce destructive fishing and collection practices that threaten coral reef and seagrass ecosystems. Adoption of OMS culture depends on demonstrating its success as a livelihood, yet few studies of OMS culture exist in the region. We present a case study of a land-based culture project for an endangered seahorse ( Hippocampus barbouri) in the Spermonde Islands, Sulawesi, Indonesia. The business model demonstrated that culturing can increase family income by seven times. A Strengths Weaknesses Opportunities Threats (SWOT) analysis indicated good collaboration among diverse stakeholders and opportunities for culturing non-endangered species and for offshoot projects, but complicated permitting was an issue as were threats of market flooding and production declines. The OMS international market is strong, Indonesian exporters expressed great interest in cultured product, and Indonesia is the largest exporting country for H. barbouri. Yet, a comparison of Indonesia ornamental marine fish exports to fish abundance in a single local market indicated that OMS culture cannot replace fishing livelihoods. Nevertheless, seahorse and other OMS culture can play a role in management and conservation by supplementing and diversifying the fishing and collecting livelihoods in the developing nations that provide the majority of the global OMS.

This research is intended to develop a 'hybrid compression/absorption type heat utilization system' by combining an absorption process with a compression process in one circulation cycle. This system can produce chilling heat for ice thermal storage by utilizing low-temperature waste heat (lower than 100 C) which is impossible to treat with a conventional absorption chiller. It means that this system will be able to solve the problem of a timing mismatch between waste heat and heat demand. The working fluid used in this proposed system should be suitable for producing ice, be safe, and not damage the ozone layer. In this project, new working fluids were searched as substitutes for the existing H{sub 2}O/LiBr or NH{sub 3}/H{sub 2}O. The interim results of this project in 1997, a testing unit using NH{sub 3}/H{sub 2}O was built for demonstration of the system and evaluation of its characteristics, and R134a/E181 was found to be one of the good working fluid for this system. The COP (ratio of energy of ice produced to electric power provided) of this system using R134a/E181 is expected to achieve 5.5 by computer simulation. The testing unit with this working fluid was built recently and prepared for the tests to confirm the result of the simulation. (orig.)

In this study, the methodology used is descriptive during the case study of culture project named I Ciclo de Estudos   Discutindo Direitos Históricos a partir do Documentário Índio Cidadão?, in that the film narrative, the documental research, and the bibliographic review are analyzed. It is discussed about the Brazilian native people rights which were declared by the Brazilian State since the Brasilian Constituent of 1987. It is reflected on the use of the film supply in the research and how it can be used in a specific way for the law study relating to the cultural projects. In relation to cultural project referred, it is questioned about the possible contributions that those actions can have in order to develop an awareness of academic society, including the acceptance and coexistence with cultural diversity at the University. It is concluded that the film source can contribute through cultural projects during the academic activities to promote the debate about the historical construction of rights and their effectiveness.

Fast Response, Load-Matching Hybrid Fuel Cell: Final Technical Progress Report

Energy Technology Data Exchange (ETDEWEB)

Key, T. S.; Sitzlar, H. E.; Geist, T. D.

2003-06-01

Hybrid DER technologies interconnected with the grid can provide improved performance capabilities compared to a single power source, and, add value, when matched to appropriate applications. For example, in a typical residence, the interconnected hybrid system could provide power during a utility outage, and also could compensate for voltage sags in the utility service. Such a hybrid system would then function as a premium power provider and eliminate the potential need for an uninterruptible power supply. In this research project, a proton exchange membrane (PEM) fuel cell is combined with an asymmetrical ultracapacitor to provide robust power response to changes in system loading. This project also considers the potential of hybrid DER technologies to improve overall power system compatibility and performance. This report includes base year accomplishments of a proposed 3-year-option project.

Methodological approaches in the research of organizational culture

Directory of Open Access Journals (Sweden)

Janićijević Nebojša

2011-01-01

Full Text Available In the thirty-years-long research of organizational culture, two mutually opposed methodological approaches have emerged: objectivistic quantitative and subjectivistic-qualitative. These two approaches are based on opposite ontological and epistemological assumptions: they include different types of research, and use opposite, quantitative vs. qualitative, methods of research. Each of the methodological approaches has its advantages and disadvantages. For this reason a hybrid approach emerges as a legitimate choice in organizational culture research methodology. It combines elements of both subjectivistic and objectivistic methodological approaches, according to the goals, content, and context of the research and preferences of the researcher himself/herself. Since it is possible to combine the two principal methodological approaches in various ways, there are several possible hybrid methodologies in organizational culture research. After the review of objectivistic quantitative and subjectivistic-qualitative methodological approaches, one of possible hybrid approaches in the research of organizational culture is presented in this paper.

Community-based participatory media projects form a promising new strategy for mental health promotion that can help address the mental health-gap identified by the World Health Organization. (2008b) mhGAP, Mental Health Gap Action Programme: Scaling Up Care for Mental, Neurological and Substance Use Disorders. World Health Organization, Geneva. In this article we present an ethnographic study about a participatory media project that was developed to promote mental health in selected Dutch low socio-economic status neighborhoods. Through narrowcastings (group film viewings), participant observation and interviews we mapped the ways in which the media project effected and facilitated the collective sense-making process of the audience with regard to sources of stress impacting mental health and opportunities for action. These determinants of mental health are shaped by cultural dimensions, since the cultural context shapes everyday experiences of stress as well as the resources and skills to manage them. Our analysis shows that the media project engaged cultural resources to challenge stressful social scripts. We conclude that more attention should be paid to cultural narratives in a community to understand how health promotion strategies can support social resilience. © The Author 2015.

From object to subject: hybrid identities of indigenous women in science

Science.gov (United States)

McKinley, Elizabeth

2008-12-01

The use of hybridity today suggests a less coherent, unified and directed process than that found in the Enlightenment science's cultural imperialism, but regardless of this neither concept exists outside power and inequality. Hence, hybridity raises the question of the terms of the mixture and the conditions of mixing. Cultural hybridity produced by colonisation, under the watchful eye of science at the time, and the subsequent life in a modern world since does not obscure the power that was embedded in the moment of colonisation. Indigenous identities are constructed within and by cultural power. While we all live in a global society whose consequences no one can escape, we remain unequal participants and globalisation remains an uneven process. This article argues that power has become a constitutive element in our own hybrid identities in indigenous people's attempts to participate in science and science education. Using the indigenous peoples of Aotearoa New Zealand (called Māori) as a site of identity construction, I argue that the move from being the object of science to the subject of science, through science education in schools, brings with it traces of an earlier meaning of `hybridity' that constantly erupts into the lives of Māori women scientists.

A Model to Investigate the Effect of Work Ethic Culture on Dynamics of Rework in Management of Projects

Directory of Open Access Journals (Sweden)

Hossein Kiani

2018-03-01

Full Text Available The present study aims to investigate the effect of work ethic culture on rework in construction projects through a review of literature, surveys, and interviews with project managers. The main research question is what mechanisms can project manager use to balance the costs of personnel training, financial and language incentives, and implementation costs to finish the project with more profit and less rework. In this regard, modelling and data analysis is done using System Dynamics methodology. The results show that by considering work ethic, rework in the project is reduced from 46 % to 39 %. However, the project has been completed with 10 % lower cost and 26 % lower variance. Integrating the issue of rework with the culture of work ethic in the field of project management by at least one exogenous parameter has been studied, while in this study qualitative parameters have been converted to quantitative parameters using fuzzy inference system. The change in management approach to the issue of work ethics and the formulation of human resource strategies of large projects by human resource managers is one of the applications of this study.

Heat driven heat transformers can upgrade heat from about 100-120 degrees Celsius to 180-200C. However, most of the waste heat is below 100C. The hybrid adsorption compression technology offers the possibility to upgrade by at least 50C. The hybrid concept combines a heat-driven heat transformer with a power-driven compression heat pump. As part of the HYACINT project it has been examined which components of the two heat pump technologies are the most suitable for application in a hybrid heat transformer. This is done through a literature survey, sociological research, model calculations and measurements of components [Dutch] Warmtegedreven warmtetransformatoren kunnen warmte vanaf ongeveer 100 a 120C opwaarderen tot warmte van 180 tot 200C. Het merendeel van de restwarmte bevindt zich echter onder 100C. De hybride adsorptie compressie technologie biedt de mogelijkheid om ook deze warmte met tenminste 50C te kunnen verhogen. Het hybride concept combineert een warmtegedreven warmtetransformator met een arbeid aangedreven compressie warmtepomp. Binnen het HYACINT project is onderzocht welke componenten van beide warmtepomp technologieen het meest geschikt zijn voor toepassing in een hybride warmtetransformator. Dit is gedaan door middel van literatuurstudie, sociaalwetenschappelijk onderzoek, toepassingspotentieelonderzoek, modelberekeningen en metingen aan componenten.

Fluorescence In Situ Hybridization (FISH Signal Analysis Using Automated Generated Projection Images

Xingwei Wang

2012-01-01

Full Text Available Fluorescence in situ hybridization (FISH tests provide promising molecular imaging biomarkers to more accurately and reliably detect and diagnose cancers and genetic disorders. Since current manual FISH signal analysis is low-efficient and inconsistent, which limits its clinical utility, developing automated FISH image scanning systems and computer-aided detection (CAD schemes has been attracting research interests. To acquire high-resolution FISH images in a multi-spectral scanning mode, a huge amount of image data with the stack of the multiple three-dimensional (3-D image slices is generated from a single specimen. Automated preprocessing these scanned images to eliminate the non-useful and redundant data is important to make the automated FISH tests acceptable in clinical applications. In this study, a dual-detector fluorescence image scanning system was applied to scan four specimen slides with FISH-probed chromosome X. A CAD scheme was developed to detect analyzable interphase cells and map the multiple imaging slices recorded FISH-probed signals into the 2-D projection images. CAD scheme was then applied to each projection image to detect analyzable interphase cells using an adaptive multiple-threshold algorithm, identify FISH-probed signals using a top-hat transform, and compute the ratios between the normal and abnormal cells. To assess CAD performance, the FISH-probed signals were also independently visually detected by an observer. The Kappa coefficients for agreement between CAD and observer ranged from 0.69 to 1.0 in detecting/counting FISH signal spots in four testing samples. The study demonstrated the feasibility of automated FISH signal analysis that applying a CAD scheme to the automated generated 2-D projection images.

No creative person is an island: Organisational culture, academic project-based creativity, and the mediating role of intra-organisational social ties

Directory of Open Access Journals (Sweden)

Leon AG Oerlemans

2014-02-01

Full Text Available This paper examines the relationship between perceptions of organizational culture, academics’ social embeddedness, and their creative paper project output. It argues that the extent to which researchers working on paper projects are socially embedded by having social ties with colleagues inside and outside their academic department (but within the same university is a causal step linking organizational values and norms to creative outputs. This study, however, does not find support for the proposed mediating effects. Instead, results indicate that three organizational culture dimensions – i.e. performance orientation, environmental orientation, and innovation support – affect employees’ creative project output through their social embeddedness outside the department (but within their own university. As the organizational culture and social embeddedness of employees outside the department are both contextual factors that (either indirectly or directly matter for the generation of creative project outputs by researchers, this study concludes that “no creative person and no project is an island”.

Full Text Available Background. Overcoming of reproductive isolation, identification and transfer of agronomic value genes from wild relatives into cultivated pea genomes is an important task for pea introgressive breeding. Materials and methods. Reciprocal hybridization of cultivated pea with wide set of P. fulvum accessions was conducted. Identification of hybrids was carried out with use of biochemical and morphological markers. Identification of unique protein was conducted with use of electrophoretic spectra of mature seeds. Results. Pea interspecific hybrids were obtained in two reciprocal directions of crosses. Cross efficiency in Р. sativum × P. fulvum and P. fulvum × Р. sativum combinations was 36 % and 7 %, respectively. All tested seeds in crosses Р. sativum × P. fulvum were hybrids. Crosses in direction P. fulvum × Р. sativum led to formation of puny seeds restricted in embryo growth. Protein markers of one seed derived in cross P. fulvum × Р. sativum proved its hybrid nature. Morphological markers demonstrated that plant derived from another cross was also a hybrid. Culture of immature embryos was developed for recovering plants in interspecific crosses. Morphogenic calli and regenerated plants were obtained in culture of immature embryos P. fulvum (И592589 × Р. sativum (Aest. Identification of unique protein 7 of P. fulvum was conducted. Inheritance of that protein was proved as monogenic dominant. Conclusion. Efficiency of hybridization in combination P. fulvum × Р. sativum was significantly less in compare to reciprocal one. All products of that cross combination were tested as hybrids. Unique protein 7 of P. fulvum was revealed as a result of mature seed electrophoretic spectra analysis. Inheritance of that protein was determined as monogenic dominant.

Molas Baju Wara: Hybridity in Manggarai Rap Music

2017-06-01

Full Text Available Rap music which has been popular since 2007 in Manggarai region, East Nusa Tenggara, Indonesia, gave rise to rap hybrid phenomenon. The mixture between American rap music formats and local elements of Manggarai attracted the attention of young people in the region. One of the local songs that feature hybridity in rap Manggarai is "Molas Baju Wara" created by Lipooz, one of the pioneers of rap in Ruteng, the capital city of Manggarai district. To discuss this phenomenon, the concept of hybridity in cultural territory proposed by James Lull is adopted. This concept is used particularly to analyze the forms of hybridity reflected in " Molas Baju Wara" and the ways they are used in showing the social and cultural conditions of Manggarai. "Molas Baju Wara" was selected as the object of study because the song is clearly showing the characteristics of hybridity in music. The study shows that hybridity could be perceived in Manggarai rap music specifically in the use of local musical instruments like drums, cajon, and tambourine as a substitute for percussive sounds of drums, boombox, or turn-table which are commonly used by rap musicians in their home country, the U.S.A. In addition, there are elements of local sound such as the sound of rain that represents Ruteng as the rain city. Hybridity characteristics can also be found in the use of Manggarai vernacular in the whole lyrics as well as the narration of local themes and certain sites that represent Ruteng.

Leaf mesophyll protoplasts of Lycopersicon esculentum (2n=2x=24) were fused with suspension culture-derived protoplasts of Solanum lycopersicoides (2n=2x=24) and intergeneric somatic hybrid plants were regenerated following selective conditions. A two phase selection system was based on the inability of S. lycopersicoides protoplasts to divide in culture in modified medium 8E and the partial inhibition of L. esculentum protoplasts by the PEG/DMSO fusion solution. At the p-calli stage, putative hybrids were visually selected based on their hybrid vigor and lime-green coloration in contrast to slower growing parental calli characterized by a watery, whitish-brown coloration. Early identification of the eight hybrid plants studied was facilitated by isozyme analysis of leaf tissue samples taken from plants in vitro at the rooting stage. Regenerated plants growing in planting medium were further verified for hybridity by 5 isozymes marking 7 loci on 5 chromosomes in tomato. These included Skdh-1 mapped to chromosome 1 of tomato, Pgm-2 on chromosome 4, Got-2 and Got-3 on chromosome 7, Got-4 on chromosome 8, and Pgi-1 and Pgdh-2 both on chromosome 12. Fraction I protein small subunits further confirmed the hybrid nature of the plants with bands of both parents expressed in all hybrids. The parental chloroplasts could not be differentiated by the isoelectric points of the large subunit. Seven of the eight somatic hybrids had a chromosome number ranging from the expected 2n=4x=48 to 2n=68. Mixoploid root-tip cells containing 48, 53, 54 or 55 chromosomes for two of the hybrids were also observed.

Shoemaker, S.A.; Fisher, J.H.; Scoggin, C.H.

1985-01-01

The traditional methods used in identifying mycobacteria, such as acid-fast bacillus stains and culture, are often time-consuming, insensitive, and nonspecific. As part of an ongoing program to improve diagnosis and characterization of mycobacteria, the authors have found that deoxyribonucleic acid (DNA) hybridization techniques using isotopically labeled, single-stranded, total DNA can be used to detect as little as 10(-4) micrograms of Mycobacterium tuberculosis (MTb) DNA. This amount of DNA represents approximately 2 X 10(4) genomes. They have also shown the MTb DNA is sufficiently different from the DNA of non-mycobacterial microorganisms such that cross-hybridization with MTb DNA does not occur under the hybridization conditions employed. The authors speculate that DNA hybridization techniques may allow the rapid, sensitive, and specific identification of mycobacteria

2015-02-01

The nuclear hybrid energy concept is becoming a reality for the US energy infrastructure where combinations of the various potential energy sources (nuclear, wind, solar, biomass, and so on) are integrated in a hybrid energy system. This paper focuses on challenges facing a hybrid system with a Small Modular Reactor at its core. The core of the paper will discuss efforts required to develop supervisory control center that collects data, supports decision-making, and serves as an information hub for supervisory control center. Such a center will also be a model for integrating future technologies and controls. In addition, advanced operations research, thermal cycle analysis, energy conversion analysis, control engineering, and human factors engineering will be part of the supervisory control center. Nuclear hybrid energy infrastructure would allow operators to optimize the cost of energy production by providing appropriate means of integrating different energy sources. The data needs to be stored, processed, analyzed, trended, and projected at right time to right operator to integrate different energy sources.

Complex Modified Hybrid Projective Synchronization of Different Dimensional Fractional-Order Complex Chaos and Real Hyper-Chaos

2014-11-01

Full Text Available This paper introduces a type of modified hybrid projective synchronization with complex transformationmatrix (CMHPS for different dimensional fractional-order complex chaos and fractional-order real hyper-chaos. The transformationmatrix in this type of chaotic synchronization is a non-square matrix, and its elements are complex numbers. Based on the stability theory of fractional-order systems, by employing the feedback control technique, necessary and sufficient criteria on CMHPS are derived. Furthermore, CMHPS between fractional-order real hyper-chaotic Rössler system and other two different dimensional fractional-order complex Lorenz-like chaotic systems is provided as two examples to discuss reduced order and increased order synchronization, respectively.

CULTURE, CULTURE LEARNING AND NEW TECHNOLOGIES: TOWARDS A PEDAGOGICAL FRAMEWORK

Directory of Open Access Journals (Sweden)

Mike Levy

2007-02-01

Full Text Available This paper seeks to improve approaches to the learning and teaching of culture using new technologies by relating the key qualities and dimensions of the culture concept to elements within a pedagogical framework. In Part One, five facets of the culture concept are developed: culture as elemental; culture as relative; culture as group membership; culture as contested; and culture as individual (variable and multiple. Each perspective aims to provide a focus for thinking about culture, and thereby to provide a valid and useful point of departure for thinking about the practice of culture learning and teaching with new technologies. The referenced literature draws from a broad range of disciplines and definitions of culture. In Part Two, five projects are chosen to represent relevant technologies currently in use for culture learning: e-mail, chat, a discussion forum and a Web-based project. Each project is used to illustrate facets of the culture concept discussed in Part One with a view to identifying key elements within a pedagogical framework that can help us respond effectively to the challenge of culture learning and teaching utilising new technologies. Thus the goal is to align fundamental qualities of the culture concept with specific pedagogical designs, tasks and technologies.

Sun, Lie; Hu, Danian

2017-09-01

The construction of nine high-end technical installations (hereafter Project NGI, for Nine Great Installations or ) in the 1960s and 1970s was an indispensable part of the development of China's defense and heavy industries. The project put more than 1400 machines into operation or trial operation during the Culture Revolution (1966-1976), and they served essential technical functions in sectors such as aviation, aerospace, machinery, metallurgy, and electronics, and directly advancing the development of these fields. It took more than a decade for Project NGI to go from planning to completion-a surprisingly uninterrupted and steady development while China fell into unprecedented turmoil. One important reason for Project NGI's success was the vital leadership of Shen Hong (, 1906-1998), the technical director of the project and a high-ranking official. Supported by state leaders such as Zhou Enlai and Nie Rongzhen, Shen and his colleagues adopted a suitable roadmap for technological development, coordinated the best-performing manufacturing forces in the country, and successfully manufactured the NGI machines. Project NGI is significant for the history of Chinese science, technology, and medicine during the Cultural Revolution not because it was technologically original, but because it represents an extraordinary case, in which the project's technological development seemed to be largely exempted from the interference of the turbulent Cultural Revolution. The project's national defense orientation, its pragmatism, and the contemporary dogma of self-reliance (), in addition to Shen Hong's political maneuvering, all contributed to the creation of a relatively calm and favorable environment around Project NGI. Despite the widespread turmoil in the country, Shen managed to assemble a stable and continuously productive team, which executed experiments, absorbed previously introduced Soviet technologies, stayed informed about advanced European and American technologies

Opening up the solar box: Cultural resource management and actor network theory in solar energy projects in the Mojave Desert

Science.gov (United States)

Gorrie, Bryan F.

This project considers the ways that Actor-Network Theory (ANT) can be brought to bear upon Cultural Resource Management (CRM) practices on renewable energy projects. ANT is a way of making inquiry into scientific knowledge practices and as CRM is intended to preserve environmental, historic, and prehistoric resources, it necessarily involves certain kinds of knowledge generation about regions in which projects are being developed. Because the practice of CRM is complex, involving a range of actors from developers to biologists, native peoples to academics, private landholders to environmental and cultural activists, it is imperative to account for the interests of all stakeholders and to resist devolving into the polemical relations of winners and losers, good and bad participants, or simple situations of right and wrong. This project intends to account for the "matters of concern" of various actors, both primary and secondary, by examining the case study of a single solar installation project in the Mojave Desert. A theoretical description of ANT is provided at the beginning and the concerns of this theory are brought to bear upon the case study project through describing the project, discussing the laws governing CRM on federal lands and in the state of California, and providing the points of view of various interviewees who worked directly or indirectly on various aspects of CRM for the solar project. The creators of ANT claim that it is not a methodology but it does speak to ethnomethodologies in that it insists that there is always something more to learn from inquiring into and describing any given situation. These descriptions avoid generalizations, providing instead various points of entry, from diverse perspectives to the project. There is an invitation to avoid assuming that one knows all there is to know about a given situation and to choose instead to continue investigating and thus give voice to the more obscure, often marginalized, voices in the

Williams, T.A.

1999-01-01

Hybrid power towers offer a number of advantages over solar-only power tower systems for early commercial deployment of the technology. These advantages include enhanced modularity, reduced financial and technical risks, and lower energy costs. With the changes in the domestic and world markets for bulk power, hybrid power towers are likely to have the best opportunities for power projects. This paper discusses issues that are likely to be important to the deployment of hybrid power towers in the near future. A large number of alternative designs are possible, and it is likely that there is no single approach that can be considered best or optimal for all project opportunities. The preferred design will depend on the application, as well as the unique objectives and perspectives of the person evaluating the design

Soft city culture and technology the Betaville Project

CERN Document Server

Skelton, Carl

2014-01-01

Soft City Culture and Technology: The Betaville Project discusses the complete cycle of conception, development, and deployment of the Betaville platform. Betaville is a massively participatory online environment for distributed 3D design and development of proposals for changes to the built environment– an experimental integration of art, design, and software development for the public realm. Through a detailed account of Betaville from a Big Crazy Idea to a working "deep social medium", the author examines the current conditions of performance and accessibility of hardware, software, networks, and skills that can be brought together into a new form of open public design and deliberation space, for and spanning and integrating the disparate spheres of art, architecture, social media, and engineering. Betaville is an ambitious enterprise, of building compelling and constructive working relationships in situations where roles and disciplinary boundaries must be as agile as the development process of the soft...

Participatory Methods and UCA Project: understanding technologies as culture

Magda Pischetola

2015-12-01

Full Text Available Abstract In the complex and changing context of digital culture, the media become an important space of relation, as they have the crucial role of articulating new cultural logics that lead to disruptions in the school environment. To understand this change, new methods of analysis and research have been created, the so-called Participatory Methodologies. They are action research strategies aimed at intervening in a given social situation. In the analysis proposed here, such methodologies will help us to address the challenge of involving digital technologies in school culture, through the participation of different individuals involved. Two qualitative case studies about the project Um Computador por Aluno – the Brazilian One Laptop per Child -, carried out in 2012 in the schools of Santa Catarina and Bahia, are the first of two phases of the research presented. The results concern a "vertical" form of technology insertion in schools, which led to frustration and de-motivation at several levels. Starting from these considerations, the second stage of research proposes a pedagogical intervention in one of four schools in the field. The methodologies of participatory video and photography are chosen as possibilities of action-reflection-action on the sociocultural reality of students through the experience of sharing. The results show the importance of carrying out creative activities, appropriate to a social conception of learning, as well as the centrality of children and youth as agency and a broader need to redefine the relationship between teacher and student, in a more "horizontal" perspective process of teaching and learning.

2017-07-01

Full Text Available Due to the increasing size of the population, society faces several challenges for sustainable and adequate agricultural production, quality, distribution, and food safety in the strategic project portfolio selection (SPPS. The initial adaptation of strategic portfolio management of genetically modified (GM Agro by-products (Ab-Ps is a huge challenge in terms of processing the agro food product supply-chain practices in an environmentally nonthreatening way. As a solution to the challenges, the socio-economic characteristics for SPPS of GM food purchasing scenarios are studied. Evaluation and selection of the GM agro portfolio management are the dynamic issues due to physical and immaterial criteria involving a hybrid multiple criteria decision making (MCDM approach, combining modified grey Decision-Making Trial and Evaluation Laboratory (DEMATEL, Multi-Attributive Border Approximation area Comparison (MABAC and sensitivity analysis. Evaluation criteria are grouped into social, differential and beneficial clusters, and the modified DEMATEL procedure is used to derive the criteria weights. The MABAC method is applied to rank the strategic project portfolios according to the aggregated preferences of decision makers (DMs. The usefulness of the proposed research framework is validated with a case study. The GM by-products are found to be the best portfolio. Moreover, this framework can unify the policies of agro technological improvement, corporate social responsibility (CSR and agro export promotion.

Hybrid intravenous digital subtraction angiography of the carotid bifurcation

International Nuclear Information System (INIS)

Burbank, F.H.; Enzmann, D.; Keyes, G.S.; Brody, W.R.

1984-01-01

A hybrid digital subtraction angiography technique and noise-reduction algorithm were used to evaluate the carotid bifurcation. Temporal, hybrid, and reduced-noise hybrid images were obtained in right and left anterior oblique projections, and both single- and multiple-frame images were created with each method. The resulting images were graded on a scale of 1 to 5 by three experienced neuroradiologists. Temporal images were preferred over hybrid images. The percentage of nondiagnostic examinations, as agreed upon by two readers, was higher for temporal alone than temporal + hybrid. In addition, also by agreement between two readers, temporal + hybrid images significantly increased the number of bifurcations seen in two views (87%) compared to temporal subtraction alone

Cutis laxa: reduced elastin gene expression in skin fibroblast cultures as determined by hybridizations with a homologous cDNA and an exon 1-specific oligonucleotide

Olsen, D.R.; Fazio, M.J.; Shamban, A.T.; Rosenbloom, J.; Uitto, J.

1988-01-01

Fibroblast cultures were established from six patients with cutis laxa, and elastin gene expression was analyzed by RNA hybridizations with a 2.5-kilobase human elastin cDNA or an exon 1-specific 35-base oligomer. Northern analyses using either probe detected mRNA transcripts of ∼ 3.5 kilobases, and no qualitative difference between the control and cutis laxa mRNAs was detected. However, quantitation of the elastin mRNA abundance by slot blot hybridizations revealed markedly reduced levels in all cutis laxa cell strains. Assuming equal translational activity of the control and cutix laxa mRNAs, the reduced mRNA levels could result in diminished elastin production, providing an explanation for the paucity of elastic fibers in the skin and other tissues in cutis laxa

Exponential lag function projective synchronization of memristor-based multidirectional associative memory neural networks via hybrid control

Science.gov (United States)

Yuan, Manman; Wang, Weiping; Luo, Xiong; Li, Lixiang; Kurths, Jürgen; Wang, Xiao

2018-03-01

This paper is concerned with the exponential lag function projective synchronization of memristive multidirectional associative memory neural networks (MMAMNNs). First, we propose a new model of MMAMNNs with mixed time-varying delays. In the proposed approach, the mixed delays include time-varying discrete delays and distributed time delays. Second, we design two kinds of hybrid controllers. Traditional control methods lack the capability of reflecting variable synaptic weights. In this paper, the controllers are carefully designed to confirm the process of different types of synchronization in the MMAMNNs. Third, sufficient criteria guaranteeing the synchronization of system are derived based on the derive-response concept. Finally, the effectiveness of the proposed mechanism is validated with numerical experiments.

Full Text Available This paper provides the results of an exploratory survey of construction industry managersin Singapore to isolate some of the common effects of national and organisational culture,together with the personal characteristics of managers, on the efficacy of project communication.By examination of significant correlation coefficients, the various types of influencesare identified. The results of the research suggest that the managers’ attitude andbehaviours toward communication may be guided to large extent by their level of competence.The study also provides evidence to suggest that the individuals’ understanding ofthe communication process and its barriers, the way they behave with other individualsand expect to be treated, varies according to national cultures.

Full Text Available With the revolutionary triumph I Cuba, a deep transformation of all the socio-economic, political and cultural structures is started. As part of this dynamics a process of institutionalization which finds in the scope of culture one of its higher referents in the creation of Casa de las Americas in July 1959 starts. The needs of legitimation of the new system found in the institution a mechanism to encourage and stimulate the revolutionary ideas and its projections towards Latin-America. In the period from 1959 to 1965, through its main actions, understood as its magazine and contest, the intellectual compromise as principal foundation of its discourse was authenticated.

Conceptualizing the cross-cultural gaps in managing international aid: HIV/AIDS and TB project delivery in Southern Africa.

Science.gov (United States)

Jackson, Terence

2011-01-01

There appears to be a gap between the billions of dollars inputted into fighting HIV/AIDS and TB and outcomes. This in part can be attributed to the lack of attention in International Development to managing programmes and projects within complex levels of cross-cultural interactions. International Development often ignores management issues, yet Management Studies is left wanting through a lack of engagement with development issues including the fight against disease and poverty. This paper attempts to link these two disciplines towards mutual benefit, through a critical cross-cultural approach. It provides contextualization of international development policies/strategies; conceptualization of dominant paradigms; structural analysis of how a programme/project fits into the global governance structure; analysis of complexities and levels of cross-cultural interaction and their consequences and the process and implications of knowledge transfer across cultural distances. It concludes with implications for policy and practice, as well as what is needed from cross-disciplinary research. This includes how feedback loops can be strengthened from local to global, how indigenous knowledge may be better understood and integrated, how power relations within the global governance structure could be managed, how cross-cultural interaction could be better understood, and how knowledge transfer/sharing should be critically managed.

Projective-anticipating, projective and projective-lag synchronization of chaotic systems with time-varying delays

International Nuclear Information System (INIS)

Feng Cunfang; Guan Wei; Wang Yinghai

2013-01-01

We investigate different types of projective (projective-anticipating, projective and projective-lag) synchronization in unidirectionally nonlinearly coupled time-delayed chaotic systems with variable time delays. Based on the Krasovskii–Lyapunov approach, we find both the existence and sufficient stability conditions, using a general class of time-delayed chaotic systems related to optical bistable or hybrid optical bistable devices. Our method has the advantage that it requires only one nonlinearly coupled term to achieve different types of projective synchronization in time-delayed chaotic systems with variable time delays. Compared with other existing works, our result provides an easy way to achieve projective-anticipating, projective and projective-lag synchronization. Numerical simulations of the Ikeda system are given to demonstrate the validity of the proposed method. (paper)

Hybrid vehicle assessment. Phase I. Petroleum savings analysis

Energy Technology Data Exchange (ETDEWEB)

Levin, R.; Liddle, S.; Deshpande, G.; Trummel, M.; Vivian, H.

1984-03-01

This report presents the results of a comprehensive analysis of near-term electric-hybrid vehicles. Its purpose was to estimate their potential to save significant amounts of petroleum on a national scale in the 1990s. Performance requirements and expected annual usage patterns of these vehicles were first modeled. The projected US fleet composition was estimated, and conceptual hybrid vehicle designs were conceived and analyzed for petroleum use when driven in the expected annual patterns. These petroleum consumption estimates were then compared to similar estimates for projected 1990 conventional vehicles having the same performance and driven in the same patterns. Results are presented in the form of three utility functions and comparisons of several conceptual designs are made. The Hybrid Vehicle (HV) design and assessment techniques are discussed and a general method is explained for selecting the optimum energy management strategy for any vehicle-mission-battery combination. A discussion of lessons learned during the construction and test of the General Electric Hybrid Test Vehicle is also presented. Conclusions and recommendations are presented, and development recommendations are identified.

“hubris” that is so much taken for granted in contemporary science and engineering discourses and practices with a sense of cooperation and social responsibility. The book portrays the history of science and technology as an underlying tension between hubris – literally the ambition to “play god...... an alternative approach, devoting special attention to the role played by social and cultural movements in the making of science and technology. They show how social and cultural movements, from the Renaissance of the late 15th century to the environmental and global justice movements of our time, have provided......” on the part of many a scientist and engineer and neglect the consequences - and a hybrid imagination, connecting scientific “facts” and technological “artifacts” with cultural understanding.

Converging Ideologies in William Fowler’s Hybrid Translation of Machiavelli’s Il Principe

Directory of Open Access Journals (Sweden)

Sergi Mainer

2014-02-01

Full Text Available This article explores the place of William Fowler’s translation of Machiavelli’s Prince in the Scottish Jacobean polysystem. Even if it was never finished, Fowler may have seen his rendering of Il Principe as a way of gaining King James’s favor at a time when Fowler had become a peripheral member at the sovereign’s court. Consequently, the translator’s hybrid deployment of three different sources, together with his own additions and suppressions, were aimed to conform to James VI’s political and cultural project. The ideological convergences between the king’s political thought and Fowler’s manipulated Prince supported and legitimized the existing power structures of the target culture. The unfinished/unedited state of the manuscript may suggest that a total reconciliation between James’s markedly idealized vision of kingship and government and Machiavelli’s treatise was impossible despite the translator’s intercultural and ethnocentric appropriation of the source text.

In situ detection of methanogens within the family Methanobacteriaceae is sometimes known to be unsuccessful due to the difficulty in permeability of oligonucleotide probes. Pseudomurein endoisopeptidase (Pei), a lytic enzyme that specifically acts on their cell walls, was applied prior to 16S rRNA-targeting fluorescence in situ hybridization (FISH). For this purpose, pure cultured methanogens within this family, Methanobacterium bryantii, Methanobrevibacter ruminantium, Methanosphaera stadtmanae, and Methanothermobacter thermautotrophicus together with a Methanothermobacter thermautotrophicus-containing syntrophic acetate-oxidizing coculture, endosymbiotic Methanobrevibacter methanogens within an anaerobic ciliate, and an upflow anaerobic sludge blanket (UASB) granule were examined. Even without the Pei treatment, Methanobacterium bryantii and Methanothermobacter thermautotrophicus cells are relatively well hybridized with oligonucleotide probes. However, almost none of the cells of Methanobrevibacter ruminantium, Methanosphaera stadtmanae, cocultured Methanothermobacter thermautotrophicus, and the endosymbiotic methanogens and the cells within UASB granule were hybridized. Pei treatment was able to increase the probe hybridization ratio in every specimen, particularly in the specimen that had shown little hybridization. Interestingly, the hybridizing signal intensity of Methanothermobacter thermautotrophicus cells in coculture with an acetate-oxidizing H2-producing syntroph was significantly improved by Pei pretreatment, whereas the probe was well hybridized with the cells of pure culture of the same strain. We found that the difference is attributed to the differences in cell wall thicknesses between the two culture conditions. These results indicate that Pei treatment is effective for FISH analysis of methanogens that show impermeability to the probe. PMID:16950902

Building on one of the world-leading technologies in fiber optics this project uncovers, whether it is realistic under Danish conditions to exploit opportunities within hybrid fiber illumination - i.e. systems that directly moves the sun indoors via fiber optics. Hybrid lighting is a combination of four technologies: the collection of sunlight (daylight), generation of artificial light, assembly, transportation and distribution of light where needed, and operational control of both natural and artificial light. Some of the significant findings from this project are a design of a hybrid system based on a solar optical system and LED technology, and design and development of fixtures that could combine both daylight and artificial light. The analysis showed that a system based on only LEDs could save 36% energy compared with a system based on the T5 (fluorescent lamps), which today is considered the best available technology. The analysis further indicates an energy saving of 59% when you combine a solar optical system with LED technology in a hybrid system. It is found that there is great potential for further design and applications which can be based for a hybrid lighting combined with the two technologies mentioned above (optical fibers and LEDs). It was also found that hybrid lighting systems are in a very early stage of the innovation life cycle and that one of the most important barriers for successful implementation is the considerably high price. However, this is a typical problem that arises with new technologies and, therefore, further development followed by pilot test projects could bring this technology fast to a more competitive phase, even if one as the basis selects systems based on the T5 technology. There is widespread acceptance of the hybrid system by office users in many areas where it is not possible to have windows, but to make the system work in other sectors, it is necessary to continue research in design that can provide a greater light

Non-invasive landscape investigation for archaeological purposes includes a wide range of survey techniques, most of which include in-situ methods. In the recent years, a major advance in the non-invasive surveying techniques has been the introduction of active remote sensing technologies. One of such technologies is spaceborne radar, known as Synthetic Aperture Radar (SAR). SAR has proven to be a valuable tool in the analysis of potential archaeological marks and in the systematic cultural heritage site monitoring. With the use of SAR, it is possible to monitor slight variations in vegetation and soil often interpreted as archaeological signs, while radar sensors frequently having penetrating capabilities offering an insight into shallow underground remains. Radar remote sensing for immovable cultural heritage and archaeological applications has been recently introduced to Cyprus through the currently ongoing ATHENA project. ATHENA project, under the Horizon 2020 programme, aims at building a bridge between research institutions of the low performing Member States and internationally-leading counterparts at EU level, mainly through training workshops and a series of knowledge transfer activities, frequently taking place on the basis of capacity development. The project is formed as the consortium of the Remote Sensing and Geo-Environment Research Laboratory of the Cyprus University of Technology (CUT), the National Research Council of Italy (CNR) and the German Aerospace Centre (DLR). As part of the project, a number of cultural heritage sites in Cyprus have been studied testing different methodologies involving SAR imagery such as Amplitude Change Detection, Coherence Calculation and fusion techniques. The ATHENA's prospective agenda includes the continuation of the capacity building programme with upcoming training workshops to take place while expanding the knowledge of radar applications on conservation and risk monitoring of cultural heritage sites through

The reference mirror hybrid reactor design performed by LLL and General Atomic is summarized. The reactor parameters have been chosen to minimize the cost of producing fissile fuel for consumption in fission power reactors. As in the past, we have emphasized the use of existing technology where possible and a minimum extrapolation of technology otherwise. The resulting reactor may thus be viewed as a comparatively near-term goal of the fusion program, and we project improved performance for the hybrid in the future as more advanced technology becomes available

This article is synthesis of the investigation to choose I in environment title of Master and Development of the National University of Host Colombia Medellin, on the speech, the social images and representations that emerge in the Studies from environmental Impact -EIA- from the cultural systems from communities affected by the implantation and operation. From two macro projects, that are part of the Plans of national Development, regional and local in Colombia: one, the Project Pilot of Generation of Aeolian Energy Jepirachi, in Colombian the Guajira discharge that affects indigenous communities of several establishments Wayuu in the sector of Average Moon. The other, the project of Road Connection between Valleys of the Aburra River - and the Cauca River, which it affects communities that inhabit an axis of rural transition - urban, whose cultural composition is diverse in its origin, mobility and interactions. It was left from two hypotheses: one, is that the analysis made in the cultural dimension of the EIA, is insufficient lo identify, lo evaluate and to handle the impacts on the cultural systems; second, front lo the treatment of the cultural systems is the existence of fundamental differences. There is cultural systems in Colombia which status is recognized greater and category than to others. The analysis of the speech allowed to obtain a diagnosis on semantic the rhetorical structure and - formal and textual cohesion, coherence, correlations and associations in the EIA and to identify the social images and representations that emerge on the populations taken part by the projects. Finally conclusions. That consider they leave to the debate on the cultural analyses that have been made in the EIA ,their emptiness and limitations and the different courses open that can take futures works from investigation

'The significant problems we face cannot be solved at the same level of thinking we were at when we created them.' Albert Einstein. I've identified an initial set of three perspectives important to building an integrated, comprehensive approach to managing the environment - technical, institutional, and cultural. I've constructed an holistic model (called the Environmental Trilogy) for environmental management, encompassing at least these three perspectives and their interrelationships. In this paper, I outline the model and report the results of a working session facilitated at Virginia Tech in Blacksburg, Virginia, in October 1991, involving three representatives from each of the technical, institutional, and cultural perspectives. The institutional members of this group were people who understand institutional effects, rather than those who represent institutions. The working group discussed and analyzed the technical-institutional, technical-cultural, and institutional-cultural inter- relationships of the environmental trilogy. The goals of the working group were to put structure on the environmental trilogy model, to facilitate the definition of variables, and explore relationships between and among variables. The working group members are to continue studying issues and components, perspectives, connections, and cause-and-effect in the models and report back to interested parties. The outcome is projected to be a more holistic, integrated view of the environment. (author)

The purpose of this research is to design pilot projects for introducing hybrid buses into the public transportation sector. This research also covers contents regarding hybrid buses with a trolley-collector motor and a diesel engine, to identify technical and economical problems and to analyze cost beneficiation using hybrid buses. The trolley parallel hybrid system has been employed for the feasibility study. This system has abundant operation results in Europe and the USA. Its battery is small or is not necessary, and the maintenance cost is also low. As a result of the feasibility study, reduction effects of CO2 emission were found out. When the CO2 generation at the power plant is not counted, the reduction effect was estimated to be 32% compared with the CO2 emission from diesel buses. When the CO2 generation at the power plant is considered, it was estimated to be 18%. The cost beneficiation was investigated for the cases of the transportations using trolley system surrounding a medium-scale terminal among large-scale housing development, tourist resort, and stations. The annual income is estimated to be larger than the annual payment in each case. It was found that the hybrid bus is economically established. 17 refs., 48 figs., 41 tabs.

Project Startup: Evaluating the Performance of Hydraulic Hybrid Refuse Vehicles

Energy Technology Data Exchange (ETDEWEB)

2015-09-01

The Fleet Test and Evaluation Team at the National Renewable Energy Laboratory (NREL) is evaluating the in-service performance of 10 next-generation hydraulic hybrid refuse vehicles (HHVs), 8 previous-generation HHVs, and 8 comparable conventional diesel vehicles operated by Miami-Dade County's Public Works and Waste Management Department in southern Florida. The HHVs under study - Autocar E3 refuse trucks equipped with Parker Hannifin's RunWise Advanced Series Hybrid Drive systems - can recover as much as 70 percent of the energy typically lost during braking and reuse it to power the vehicle. NREL's evaluation will assess the performance of this technology in commercial operation and help Miami-Dade County determine the ideal routes for maximizing the fuel-saving potential of its HHVs.

The NSF EarthCube Integration and Test Environment (ECITE) has built a hybrid cloud computing environment to provides cloud resources from private cloud environments by using cloud system software - OpenStack and Eucalyptus, and also manages public cloud - Amazon Web Service that allow resource synchronizing and bursting between private and public cloud. On ECITE hybrid cloud platform, EarthCube and geoscience community can deploy and manage the applications by using base virtual machine images or customized virtual machines, analyze big datasets by using virtual clusters, and real-time monitor the virtual resource usage on the cloud. Currently, a number of EarthCube projects have deployed or started migrating their projects to this platform, such as CHORDS, BCube, CINERGI, OntoSoft, and some other EarthCube building blocks. To accomplish the deployment or migration, administrator of ECITE hybrid cloud platform prepares the specific needs (e.g. images, port numbers, usable cloud capacity, etc.) of each project in advance base on the communications between ECITE and participant projects, and then the scientists or IT technicians in those projects launch one or multiple virtual machines, access the virtual machine(s) to set up computing environment if need be, and migrate their codes, documents or data without caring about the heterogeneity in structure and operations among different cloud platforms.

In recent years, some workshops and research cases have arisen in China to seek for suitable ways for heritage conservation and development of historic villages. However, the issue of multi-cooperation has not been much mentioned in research works. The case of Cangdong Project in Guangdong Province is a social enterprise. It is a center focusing on heritage education. It organizes tailor-made workshops for interested people from all over China and Hong Kong, Macao and overseas, including university courses for credits, summer/winter camps for primary and middle school students, as well as common people who are interested in heritage conservation. The purpose of the education center is to enhance heritage/cultural interest of the younger generations and common people, and try to work with local villagers to build a wealthy community. Nowadays, more and more villagers moved out for work and the countryside population in China is decreasing, this project also aims to create work opportunities for villagers through heritage conservation projects, so that the villagers can be willing to stay. The project focuses more in a sustainable way for community development. It has been five years since the project was set up in Cangdong Village. The project team worked with villagers, city people, students, scholars, different levels of local governments, investors, Medias, charitable organizations, as well as the market of tourism. As such, a platform of multi-cooperation for the above parties has formed during the past five years. This paper takes the Project experience from 2010-2015 as the case to study multi-cooperation in the field of heritage conservation in China, as well as to discuss how to co-operate the subjective initiatives of different stokeholds.

An investigation has been conducted to examine the impact of fusion-fission hybrids on world nuclear future. The primary objectives of this investigation have been: (1) to determine whether hybrids can allow us to meet the projected nuclear component of the world energy demand within current estimates of uranium resources without fast breeders, and (2) to identify the preferred hybrid concept from a resource standpoint. The results indicate that hybrids have the potential to lower the world uranium demand to values well below the resource base. However, the time window for hybrid introduction is quite near and narrow (2000-2020). If historical market penetration rates are assumed, the demand will not be met within the resource base unless hybrids are coupled to the breeders. The results also indicate that from a resource standpoint hybrids which breed their own tritium and have a low blanket energy multiplication are preferable. (orig.) [de

The authors have generated a Chinese hamster V79/380-6 HPRT minus x human leukocyte hybrid cell line (18/V79) with chromosome 18 as the only human chromosome that is retained at high frequency without specific selection. Hybrid cells were selected in HAT medium, and 164 individual colonies were isolated. Of 110 colonies screened for human DNA by PCR amplification using a primer specific for human Alu repeats 67 (61%) were positive. These were expanded in culture for large-scale DNA preparations. Retesting expanded clones by PCR with Alu and LINE primers has revealed unique patterns of amplification products. In situ hybridization of biotin labelled total human DNA to metaphase spreads from various hybrids revealed the presence of one or more human DNA fragments integrated in hamster chromosomes. The authors have generated a resource that should allow the construction of a radiation map, to be compared with the YAC contig map also under construction in their laboratory

This project completed a modeling evaluation of a hybrid gas water heater that combines a reduced capacity tankless unit with a downsized storage tank. This product would meet a significant market need by providing a higher efficiency gas water heater solution for retrofit applications while maintaining compatibility with the 1/2 inch gas lines and standard B vents found in most homes. The TRNSYS simulation tool was used to model a base case 0.60 EF atmospheric gas storage water, a 0.82 EF non-condensing gas tankless water heater, an existing (high capacity) hybrid unit on the market, and an alternative hybrid unit with lower storage volume and reduced gas input requirements. Simulations were completed under a 'peak day' sizing scenario with 183 gpd hot water loads in a Minnesota winter climate case. Full-year simulations were then completed in three climates (ranging from Phoenix to Minneapolis) for three hot water load scenarios (36, 57, and 96 gpd). Model projections indicate that the alternative hybrid offers an average 4.5% efficiency improvement relative to the 0.60 EF gas storage unit across all scenarios modeled. The alternative hybrid water heater evaluated does show promise, but the current low cost of natural gas across much of the country and the relatively small incremental efficiency improvement poses challenges in initially building a market demand for the product.

The results of a comprehensive analysis of near term electric hybrid vehicles are presented, with emphasis on their potential to save significant amounts of petroleum on a national scale in the 1990s. Performance requirements and expected annual usage patterns of these vehicles are first modeled. The projected U.S. fleet composition is estimated, and conceptual hybrid vehicle designs are conceived and analyzed for petroleum use when driven in the expected annual patterns. These petroleum consumption estimates are then compared to similar estimates for projected 1990 conventional vehicles having the same performance and driven in the same patterns. Results are presented in the form of three utility functions and comparisons of sevral conceptual designs are made. The Hybrid Vehicle (HV) design and assessment techniques are discussed and a general method is explained for selecting the optimum energy management strategy for any vehicle mission battery combination. Conclusions and recommendations are presented, and development recommendations are identified.

To construct a kind of bone healing enhancing implant with cultured chondrocytes bound to hydroxyapatite (HA). Chondrocytes were obtained from the costicartilage of rat and were cultured on the porous HA blocks, 3 mm x 3 mm x 4 mm size, for three and seven days. Scanning electron micrograph was taken to show whether the cells grew outside and inside the pore of HA block. The cells cultured on tiny glass sheet for 2 days were used to prove where the cells come from by in situ hybridization technique with alpha1 (II) cDNA probe. Scanning electron micrographs showed that the pores of the HA surface and inside of the blocks are filled with cultured cells, especially the longer cultured block. The cells were chondrocytes confirmed by in situ hybridization. The porous HA can be used as cell cultured substrate and chondrocyte can adhere and proliferate inside the porous HA block.

2017-12-01

Full Text Available Building on a case study of three animation companies in the Chinese cultural and creative industry, this study aims to understand how profit model innovation is promoted. Due to the rapidly changing environments and resource scarcity, cultural and creative companies need to select the appropriate profit model according to their own key resources. The study uncovers two critical factors that promote profit model innovation in animation projects: the quantity of consumers and their consumption intention. According to these two dimensions, the authors’ analysis shows profit model innovation in animation projects can be divided into Fans mode, Popular mode, Placement mode, and Failure mode, respectively. This study provides an empirical basis for advocating profit model innovation and discusses the resource requirements of Fan mode, Popular model, and Placement mode in China’s cultural and creative industry. The authors’ research also has managerial implications that might help firms promote profit model innovation. Finally, learning and promoting the profit model of China’s animation industry in the Northeast Asia area will be conducive to Northeast Asia’s cooperation and sustainable development.

Human nature, human culture: the case of cultural evolution.

Science.gov (United States)

Lewens, Tim

2017-10-06

In recent years, far from arguing that evolutionary approaches to our own species permit us to describe the fundamental character of human nature, a prominent group of cultural evolutionary theorists has instead argued that the very idea of 'human nature' is one we should reject. It makes no sense, they argue, to speak of human nature in opposition to human culture. The very same sceptical arguments have also led some thinkers-usually from social anthropology-to dismiss the intimately related idea that we can talk of human culture in opposition to human nature. How, then, are we supposed to understand the cultural evolutionary project itself, whose proponents seem to deny the distinction between human nature and human culture, while simultaneously relying on a closely allied distinction between 'genetic' (or sometimes 'organic') evolution and 'cultural' evolution? This paper defends the cultural evolutionary project against the charge that, in refusing to endorse the concept of human nature, it has inadvertently sabotaged itself.

Mohammadkazemi, Faranak; Faria, Marisa; Cordeiro, Nereida

2016-01-01

In this work, a simple and green route to the synthesis of the bacterial nanocellulose-calcium carbonate (BNC/CaCO 3 ) hybrid bionanocomposites using one-step in situ biosynthesis was studied. The CaCO 3 was incorporated in the bacterial nanocellulose structure during the cellulose biosynthesis by Gluconacetobacter xylinus PTCC 1734 bacteria. Hestrin-Schramm (HS) and Zhou (Z) culture media were used to the hybrid bionanocomposites production and the effect of ethanol addition was investigated. Attenuated total reflection Fourier transform infrared spectroscopy, field emission scanning electron microscopy, X-ray diffraction, energy-dispersive X-ray spectroscopy, inverse gas chromatography and thermogravimetric analysis were used to characterize the samples. The experimental results demonstrated that the ethanol and culture medium play an important role in the BNC/CaCO 3 hybrid bionanocomposites production, structure and properties. The BNC/CaCO 3 biosynthesized in Z culture medium revealed higher O/C ratio and amphoteric surface character, which justify the highest CaCO 3 content incorporation. The CaCO 3 was incorporated into the cellulosic matrix decreasing the bacterial nanocellulose crystallinity. This work reveals the high potential of in situ biosynthesis of BNC/CaCO 3 hybrid bionanocomposites and opens a new way to the high value-added applications of bacterial nanocellulose. - Graphical Abstract: Display Omitted - Highlights: • BNC/CaCO 3 hybrid bionanocomposites were produced using in situ biosynthesis process. • Ethanol and culture medium play an important role in the production and properties. • Z-BNC/CaCO 3 bionanocomposites revealed higher O/C ratio and amphoteric surface character. • CaCO 3 incorporated into the BNC decreased crystallinity.

Cadzow, Renee B; Craig, Mary; Rowe, Jimmy; Kahn, Linda S

2013-01-01

The purpose of this study was to evaluate a community-based diabetes education pilot project. The Neighborhood Health Talker project aimed to train and implement cultural health brokers primarily targeting communities of color to improve community members' diabetes knowledge and diabetes self-management skills. A secondary aim was to establish diabetes resource libraries accessible to communities that normally experience barriers to these resources. Recruited community members completed 1 week of formal training developed by a multidisciplinary team in Buffalo, NY. The effect of training was evaluated through the use of baseline surveys, a pretest/posttest covering all training content, and daily quizzes evaluating knowledge relevant to each of the five training modules. Trained NHTs then held at least five community conversations in various locations and administered anonymous postconversation surveys to participants. Descriptive statistics and qualitative analysis techniques were used to summarize test, quiz, and survey results. Twelve women and 1 man completed the training program. Working alone as well as in pairs, each held at least five community conversations reaching over 700 community members of all ages over 3 months and established 8 diabetes resource libraries in the community. All trainees increased their diabetes knowledge and confidence as well as their abilities to perform the tasks of a cultural health broker. Trainees also indicated that the goals they set at training initiation were met. The training was successful in increasing trainee knowledge and confidence about diabetes prevention and self-management. Participants not only developed proficiency in discussing diabetes, they also made important lifestyle changes that demonstrated their commitment to the cause and the project. Low-cost initiatives like this are easily reproducible in other communities of color and could be modified to meet the needs of other communities as well.

Modular supervisory controller for hybrid power systems

Energy Technology Data Exchange (ETDEWEB)

Lemos Pereira, A. de

2000-06-01

The power supply of remote places has been commonly provided by thermal power plants, usually diesel generators. Although hybrid power systems may constitute the most economical solution in many applications their widespread application to the electrification schemes of remote areas still depends on improvements in the issues of design and operation control. The main limitations of the present hybrid power systems technology, which are identified in this work, are related to the control and supervision of the power system. Therefore this thesis focuses on the modularity of supervisory controllers in order to design cost-competitive and reliable hybrid power systems. The modular supervisory controller created in this project is considered an important part of a system design approach that aims to overcome the technical difficulties of the current engineering practice and contribute to open the market of hybrid power systems. The term modular refers to a set of design characteristics that allows the use of basically the same supervisory controller in different projects. The modularization and standardisation of the controller include several issues such as interfacing components, communication protocols, modelling, programming and control strategies. The modularity can reduce the highly specialised system engineering related to the integration of components, operation and control. It can also avoid the high costs for installation, service and maintenance. A modular algorithm for supervisory controllers has been developed (a Matlab program called SuperCon) using an object-oriented design and it has been tested through several simulations using different hybrid system configurations and different control strategies. This thesis presents a complete control system design process which can be used as the basis for the development and implementation of intelligent and autonomous supervisory controllers for hybrid power systems with modular characteristics.

Akram, M.; Mohsan; Ashraf, M.Y.; Ahmad, R.; Waraich, E.A.

2010-01-01

An efficient and simple mass screening technique for selection of maize hybrids for salt tolerance has been developed. Genetic variation for salt tolerance was assessed in hybrid maize (Zea mays L.) using solution-culture technique. The study was conducted in solution culture exposed to four salinity levels (control, 40, 80 and 120 mM NaCl). Seven days old maize seedlings were transplanted in themopol sheet in iron tubs containing one half strength Hoagland nutrient solutions and salinized with common salt (NaCl). The experiment was conducted in the rain protected wire house of Stress Physiology Laboratory of NIAB, Faisalabad, Pakistan. Ten maize hybrids were used for screening against four salinity levels. Seedling of each hybrid was compared for their growth under saline conditions as a percentage of the control values. Considerable variations were observed in the root, shoot length and biomass of different hybrids at different salinity levels. The leaf sample analyzed for inorganic osmolytes (sodium, potassium and calcium) showed that hybrid Pioneer 32B33 and Pioneer 30Y87 have high biomass, root shoot fresh weight and high ratio and showed best salt tolerance performance at all salinity levels on overall basis.

Freed, J.J.

1982-03-01

An account is given of the development and application to cell-culture genetics of unique haploid cell lines from frog embryo developed in this laboratory. Since 1968, the main aim of this project has been to develop the haploid cell system for studies of mutagenesis in culture, particularly by ultraviolet radiation. In the course of this work we isolated chromosomally stable cell lines, derived and characterized a number of variants, and adapted cell hybridization and other methods to this material. Particular emphasis was placed on ultraviolet photobiology, including studies of cell survival, mutagenesis, and pathways of repair of uv-damaged DNA. Although at present less widely used for genetic experiments than mammalian cell lines, the frog cells offer the advantages of authentic haploidy and a favorable repertory of DNA repair pathways for study of uv mutagenesis

There is a need for various types of interventions when meeting needs of clients with psychiatric disabilities and complementary interventions may also influence their well-being. The Culture and Health project, based on complementary interventions with 270 clients, was created in a county in Sweden for clients with psychiatric disabilities and for professionals to carry out the interventions. The aim of this study was to investigate the professionals' expectations regarding the project and their clients' possibilities for participating, and to investigate the professionals' experiences of the project after its completion. Focus group data with a total of 30 professionals participating were collected. A qualitative content analysis revealed four categories of the professionals' expectations before entering the project: "Clients' own possibilities and limitations for their development and independence", "Professionals' possibilities for supporting the clients", "Societal prerequisites", and "Expectations of a new way of working". Furthermore, the analysis regarding professionals' experiences after working with the project revealed three categories: "Adopting the challenges", "Having ways of working that function - prerequisites and possibilities", and "Meeting the future - an ambition to continue". Working in the Culture and Health project together with the clients in group-based activities was perceived as beneficial, although challenges arose. When implementing cultural activities, support from stakeholder organisations is needed. © 2017 Australian College of Mental Health Nurses Inc.

Full Text Available Suitable project manager has a significant impact on successful accomplishment of the project. Managers should possess such skills in order to effectively cope with the competition. In this respect, selecting managers based on their skills can lead to a competitive advantage towards the achievement of organizational goals. selection of the suitable project manager can be viewed as a multi-criteria decision making (MCDM problem and an extensive evaluation of criteria, such as Technical skills, experience skills, Personal qualities and the related criteria must be considered in the selection process of project manager. The fuzzy set theory and MCDM methods appears as an essential tools to provide a decision framework that incorporates imprecise judgments and multi criteria nature of project manager selection process inherent in this process. This paper proposes the joint use of the Fuzzy DEMATEL (FDEMATEL and Fuzzy VIKOR methods for the decision-making process of selecting the most suitable managers for projects. First, with the opinions of the senior managers based on project management competency model (ICB-IPMA, all the criteria required for the selection are gathered. Then the FDEMATEL method is used to prioritize the importance of various criteria and FVIKOR used to rank the alternatives in a preferred order to select the best project managers from a number of alternatives. Next, a real case study used to illustrate the process of the proposed method. Finally, some conclusions are discussed at the end of this study.

Space Culture: Innovative Cultural Approaches To Public Engagement With Astronomy, Space Science And Astronautics

Science.gov (United States)

Malina, Roger F.

2012-01-01

In recent years a number of cultural organizations have established ongoing programs of public engagement with astronomy, space science and astronautics. Many involve elements of citizen science initiatives, artists’ residencies in scientific laboratories and agencies, art and science festivals, and social network projects as well as more traditional exhibition venues. Recognizing these programs several agencies and organizations have established mechanisms for facilitating public engagement with astronomy and space science through cultural activities. The International Astronautics Federation has established an Technical Activities Committee for the Cultural Utilization of Space. Over the past year the NSF and NEA have organized disciplinary workshops to develop recommendations relating to art-science interaction and community building efforts. Rationales for encouraging public engagement via cultural projects range from theory of creativity, innovation and invention to cultural appropriation in the context of `socially robust science’ as advocated by Helga Nowotny of the European Research Council. Public engagement with science, as opposed to science education and outreach initiatives, require different approaches. Just as organizations have employed education professionals to lead education activities, so they must employ cultural professionals if they wish to develop public engagement projects via arts and culture. One outcome of the NSF and NEA workshops has been development of a rationale for converting STEM to STEAM by including the arts in STEM methodologies, particularly for K-12 where students can access science via arts and cultural contexts. Often these require new kinds of informal education approaches that exploit locative media, gaming platforms, artists projects and citizen science. Incorporating astronomy and space science content in art and cultural projects requires new skills in `cultural translation’ and `trans-mediation’ and new kinds

Beyond eugenics: the forgotten scandal of hybridizing humans and apes.

Science.gov (United States)

Etkind, Alexander

2008-06-01

This paper examines the available evidence on one of the most radical ideas in the history of eugenics and utopianism. In the mid-1920s, the zoology professor Ilia Ivanov submitted to the Soviet government a project for hybridizing humans and apes by means of artificial insemination. He received substantial financing and organized expeditions to Africa to catch apes for his experiments. His project caused an international sensation. The American Association for the Advancement of Atheism announced its fund-raising campaign to support Ivanov's project but gave it a scandalously racist interpretation. Ivanov's own motivation remained unclear, as did the motivation of those in the Bolshevik government who supported Ivanov until his arrest in 1930. This paper discusses three hypothetical reasons for Ivanov's adventure: first, hybridization between humans and apes, should it be successful, would support the atheist propaganda of the Bolsheviks; second, regardless of the success of hybridization, Ivanov would catch and bring to Russia apes, which were necessary for the rejuvenation programs that were fashionable among the Bolshevik elite; and third, hybridization, should it be successful, would pave the way to the New Socialist Man whose 'construction by scientific means' was the official purpose of the Bolsheviks. Ivanov's ideas were arguably important for the American proponent of reform eugenics, Herman Muller, and for the Soviet anthropologist Boris Porshnev.

Vegetative and adaptive traits predict different outcomes for restoration using hybrids

Directory of Open Access Journals (Sweden)

Philip Crystal

2016-11-01

Full Text Available Abstract – Hybridization has been implicated as a driver of speciation, extinction, and invasiveness, but can also provide resistant breeding stock following epidemics. However, evaluating the appropriateness of hybrids for use in restoration programs is difficult. Past the F1 generation, the proportion of a progenitor’s genome can vary widely, as can the combinations of parental genomes. Detailed genetic analysis can reveal this information, but cannot expose phenotypic alterations due to heterosis, transgressive traits, or changes in metabolism or development. In addition, because evolution is often driven by extreme individuals, decisions based on phenotypic averages of hybrid classes may have unintended results. We demonstrate a strategy to evaluate hybrids for use in restoration by visualizing hybrid phenotypes across selected groups of traits relative to both progenitor species. Specifically, we used discriminant analysis to differentiate among butternut (Juglans cinerea L., black walnut (J. nigra L., and Japanese walnut (J. ailantifolia Carr. var. cordiformis using vegetative characters and then with functional adaptive traits associated with seedling performance. When projected onto the progenitor trait space, naturally occurring hybrids (J. ×bixbyi Rehd. between butternut and Japanese walnut showed introgression towards Japanese walnut at vegetative characters but exhibited a hybrid swarm at functional traits. Both results indicate that hybrids have morphological and ecological phenotypes that distinguish them from butternut, demonstrating a lack of ecological equivalency that should not be carried into restoration breeding efforts. Despite these discrepancies, some hybrids were projected into the space occupied by butternut seedlings’ 95% confidence ellipse, signifying that some hybrids were similar at the measured traits. Determining how to consistently identify these individuals is imperative for future breeding and species

2016-08-01

In this work, a simple and green route to the synthesis of the bacterial nanocellulose-calcium carbonate (BNC/CaCO{sub 3}) hybrid bionanocomposites using one-step in situ biosynthesis was studied. The CaCO{sub 3} was incorporated in the bacterial nanocellulose structure during the cellulose biosynthesis by Gluconacetobacter xylinus PTCC 1734 bacteria. Hestrin-Schramm (HS) and Zhou (Z) culture media were used to the hybrid bionanocomposites production and the effect of ethanol addition was investigated. Attenuated total reflection Fourier transform infrared spectroscopy, field emission scanning electron microscopy, X-ray diffraction, energy-dispersive X-ray spectroscopy, inverse gas chromatography and thermogravimetric analysis were used to characterize the samples. The experimental results demonstrated that the ethanol and culture medium play an important role in the BNC/CaCO{sub 3} hybrid bionanocomposites production, structure and properties. The BNC/CaCO{sub 3} biosynthesized in Z culture medium revealed higher O/C ratio and amphoteric surface character, which justify the highest CaCO{sub 3} content incorporation. The CaCO{sub 3} was incorporated into the cellulosic matrix decreasing the bacterial nanocellulose crystallinity. This work reveals the high potential of in situ biosynthesis of BNC/CaCO{sub 3} hybrid bionanocomposites and opens a new way to the high value-added applications of bacterial nanocellulose. - Graphical Abstract: Display Omitted - Highlights: • BNC/CaCO{sub 3} hybrid bionanocomposites were produced using in situ biosynthesis process. • Ethanol and culture medium play an important role in the production and properties. • Z-BNC/CaCO{sub 3} bionanocomposites revealed higher O/C ratio and amphoteric surface character. • CaCO{sub 3} incorporated into the BNC decreased crystallinity.

A cogenerative inquiry using postcolonial theory to envisage culturally inclusive science education

Science.gov (United States)

Adams, Jennifer; Luitel, Bal Chandra; Afonso, Emilia; Taylor, Peter Charles

2008-12-01

This forum constitutes a cogenerative inquiry using postcolonial theory drawn from the review paper by Zembylas and Avraamidou. Three teacher educators from African, Asian and Caribbean countries reflect on problems confronting their professional practices and consider the prospects of creating culturally inclusive science education. We learn that in Mozambique, Nepal and the Caribbean scientism patrols the borders of science education serving to exclude local epistemological beliefs and discourses and negating culturally contextualized teaching and learning. Despite the diverse cultural hybridities of these countries, science education is disconnected from the daily lives of the majority of their populations, serving inequitably the academic Western-oriented aspirations of an elite group who are "living hybridity but talking scientism." The discussants explore their autobiographies to reveal core cultural values and beliefs grounded in their non-Western traditions and worldviews but which are in conflict with the Western Modern Worldview (WMW) and thus have no legitimate role in the standard school/college science classroom. They reflect on their hybrid cultural identities and reveal the interplay of multiple selves grounded in both the WMW and non-WMWs and existing in a dialectical tension of managed contradiction in a Third Space. They argue for dialectical logic to illuminate a Third Space wherein students of science education may be empowered to challenge hegemonies of cultural reproduction and examine reflexively their own identities, coming to recognize and reconcile their core cultural beliefs with those of Western modern science, thereby dissipating otherwise strongly delineated cultural borders.

Highlights: • The economic, environmental, technical, social and risk criteria are considered. • Prioritization of regions for construction of solar power plants in Iran is assessed. • A hybrid MCDM approach ranked 25 scattered cities all around the country. • SWARA ranked the identified criteria, and WASPAS prioritized the alternatives. • Considering the ranked cities, a comprehensive GIS map of the country is provided. - Abstract: One of the promising ways to shift towards sustainable development has been the utilization of solar energy worldwide. Based on its geographical specifications, Iran enjoys high solar potential to implement feasible solar energy projects. However, to obtain the best productivity and payback, identification and prioritization of suitable regions for construction of expensive solar power plants is a delicate issue. In contrast with common assumptions, identifying appropriate geographical regions for implementation of such projects is not only associated with the amount of received solar radiation, but also there are many economic, environmental, technical, social and risk criteria (and their relevant sub-criteria) which must be taken into account. To address the complicated nature of the prioritization challenge caused by existence of various indicators, this paper applies a hybrid Multi-Criteria Decision Making (MCDM) approach and prioritizes 25 scattered cities all around the country for implementation of future solar power plants. For this, both quantitative and qualitative effective indicators are identified to be considered as the inputs to the utilized hybrid model. The Step-wise Weight Assessment Ratio Analysis (SWARA, proposed in 2010) method is employed to rank the identified criteria, and the Weighted Aggregates Sum Product Assessment (WASPAS, proposed in 2012) is applied to evaluate and prioritize the alternatives (cities) where Yazd city ranked first. Eventually via considering the ranked cities, a comprehensive GIS

Elements de conception d'un systeme geothermique hybride par optimisation financiere

Henault, Benjamin

The choice of design parameters for a hybrid geothermal system is usually based on current practices or questionable assumptions. In fact, the main purpose of a hybrid geothermal system is to maximize the energy savings associated with heating and cooling requirements while minimizing the costs of operation and installation. This thesis presents a strategy to maximize the net present value of a hybrid geothermal system. This objective is expressed by a series of equations that lead to a global objective function. Iteratively, the algorithm converges to an optimal solution by using an optimization method: the conjugate gradient combined with a combinatorial method. The objective function presented in this paper makes use of a simulation algorithm for predicting the fluid temperature of a hybrid geothermal system on an hourly basis. Thus, the optimization method selects six variables iteratively, continuous and integer type, affecting project costs and energy savings. These variables are the limit temperature at the entry of the heat pump (geothermal side), the number of heat pumps, the number of geothermal wells and the distance in X and Y between the geothermal wells. Generally, these variables have a direct impact on the cost of the installation, on the entering water temperature at the heat pumps, the cost of equipment, the thermal interference between boreholes, the total capacity of geothermal system, on system performance, etc. On the other hand, the arrangement of geothermal wells is variable and is often irregular depending on the number of selected boreholes by the algorithm. Removal or addition of one or more borehole is guided by a predefined order dicted by the designer. This feature of irregular arrangement represents an innovation in the field and is necessary for the operation of this algorithm. Indeed, this ensures continuity between the number of boreholes allowing the use of the conjugate gradient method. The proposed method provides as outputs the

The development of low cost solar cells has been the main focus in recent years. This has lead to the generation of photovoltaic cells based on hybrid of nanoparticle-organic polymer materials. This type of hybrid photovoltaic cells can overcome the problem of polymeric devices having low optical absorption and carrier mobilities. The hybrid cell has the potential of bridging the efficiency gap, which in present in organic and inorganic semiconductor materials. This project focuses on obtaining an hybrid active layer consisting of nanoparticles and organic polymer, to understand the parameter involved in obtaining this active layer and finally to investigate if the addition of nano particles in to the active layer could enhance the output of the hybrid solar cell. The hybrid active layer have will be deposited using the spin coating technique by using CdTe, CdS nano particles mixed with poly (2-methoxy,5-(2-ethyl-hexyloxy)-p-phenylvinylene)MEH-PPV.

A HYBRID HEURISTIC ALGORITHM FOR SOLVING THE RESOURCE CONSTRAINED PROJECT SCHEDULING PROBLEM (RCPSP

Directory of Open Access Journals (Sweden)

Juan Carlos Rivera

Full Text Available The Resource Constrained Project Scheduling Problem (RCPSP is a problem of great interest for the scientific community because it belongs to the class of NP-Hard problems and no methods are known that can solve it accurately in polynomial processing times. For this reason heuristic methods are used to solve it in an efficient way though there is no guarantee that an optimal solution can be obtained. This research presents a hybrid heuristic search algorithm to solve the RCPSP efficiently, combining elements of the heuristic Greedy Randomized Adaptive Search Procedure (GRASP, Scatter Search and Justification. The efficiency obtained is measured taking into account the presence of the new elements added to the GRASP algorithm taken as base: Justification and Scatter Search. The algorithms are evaluated using three data bases of instances of the problem: 480 instances of 30 activities, 480 of 60, and 600 of 120 activities respectively, taken from the library PSPLIB available online. The solutions obtained by the developed algorithm for the instances of 30, 60 and 120 are compared with results obtained by other researchers at international level, where a prominent place is obtained, according to Chen (2011.

2012-01-01

Monica Haage described a project for Kozloduy Nuclear Power Plant in Bulgaria which was also funded by the Norwegian government. This project included the development of guidance documents and training on self-assessment and continuous improvement of safety culture. A draft IAEA safety culture survey was also developed as part of this project in collaboration with St Mary's University, Canada. This project was conducted in parallel with an IAEA project to develop new safety reports on safety culture self-assessment and continuous improvement. A safety report on safety culture during the pre-operational phases of NPPs has also been drafted. The IAEA approach to safety culture assessment was outlined and core principles of the approach were discussed. These include the use of several assessment methods (survey, interview, observation, focus groups, document review), and two distinct levels of analysis. The first is a descriptive analysis of the observed cultural characteristics from each assessment method and overarching themes. This is followed by a 'normative' analysis comparing what has been observed with the desirable characteristics of a strong, positive, safety culture, as defined by the IAEA safety culture framework. The application of this approach during recent Operational Safety Assessment Review Team (OSART) missions was described along with key learning points

This project is in support of our national goal to reduce our dependence on fossil fuels. By supporting efforts that contribute toward the successful mass production of plug-in hybrid electric vehicles, our nation’s transportation-related fuel consumption can be offset with energy from the grid. Over four and a half years ago, when this project was originally initiated, plug-in electric vehicles were not readily available in the mass marketplace. Through the creation of a 21 unit plug-in hybrid vehicle fleet, this program was designed to demonstrate the feasibility of the technology and to help build cross-industry familiarity with the technology and interface of this technology with the grid. Ford Escape PHEV Demonstration Fleet 3 March 26, 2014 Since then, however, plug-in vehicles have become increasingly more commonplace in the market. Ford, itself, now offers an all-electric vehicle and two plug-in hybrid vehicles in North America and has announced a third plug-in vehicle offering for Europe. Lessons learned from this project have helped in these production vehicle launches and are mentioned throughout this report. While the technology of plugging in a vehicle to charge a high voltage battery with energy from the grid is now in production, the ability for vehicle-to-grid or bi-directional energy flow was farther away than originally expected. Several technical, regulatory and potential safety issues prevented progressing the vehicle-to-grid energy flow (V2G) demonstration and, after a review with the DOE, V2G was removed from this demonstration project. Also proving challenging were communications between a plug-in vehicle and the grid or smart meter. While this project successfully demonstrated the vehicle to smart meter interface, cross-industry and regulatory work is still needed to define the vehicle-to-grid communication interface.

1977-06-01

A preliminary economic analysis of a hybrid geothermal/coal power plant was completed for four geothermal resource areas: Roosevelt Hot Springs, Coso Hot Springs, East Mesa, and Long Valley. A hybrid plant would be economically viable at Roosevelt Hot Springs and somewhat less so at Coso Hot Springs. East Mesa and Long Valley show no economic promise. A well-designed hybrid plant could use geothermal energy for boiler feedwater heating, auxiliary power, auxiliary heating, and cooling water. Construction and operation of a hybrid plant at either Roosevelt Hot Springs or Coso Hot Springs is recommended. A modified version of the Lawrence Berkeley Livermore GEOTHM Program is the major analytical tool used in the analysis. The Intermountain Power Project is the reference all coal-fired plant.

Purpose: The overall goal of this study is to restore kilovoltage computed tomography (kV-CT) images which are disfigured by patients’ metal prostheses. By generating a hybrid sinogram that is a combination of kV and megavoltage (MV) projection data, the authors suggest a novel metal artifact-reduction (MAR) method that retains the image quality to match that of kV-CT and simultaneously restores the information of metal prostheses lost due to photon starvation. Methods: CT projection data contain information about attenuation coefficients and the total length of the attenuation. By normalizing raw kV projections with their own total lengths of attenuation, mean attenuation projections were obtained. In the same manner, mean density projections of MV-CT were obtained by the normalization of MV projections resulting from the forward projection of density-calibrated MV-CT images with the geometric parameters of the kV-CT device. To generate the hybrid sinogram, metal-affected signals of the kV sinogram were identified and replaced by the corresponding signals of the MV sinogram following a density calibration step with kV data. Filtered backprojection was implemented to reconstruct the hybrid CT image. To validate the authors’ approach, they simulated four different scenarios for three heads and one pelvis using metallic rod inserts within a cylindrical phantom. Five inserts describing human body elements were also included in the phantom. The authors compared the image qualities among the kV, MV, and hybrid CT images by measuring the contrast-to-noise ratio (CNR), the signal-to-noise ratio (SNR), the densities of all inserts, and the spatial resolution. In addition, the MAR performance was compared among three existing MAR methods and the authors’ hybrid method. Finally, for clinical trials, the authors produced hybrid images of three patients having dental metal prostheses to compare their MAR performances with those of the kV, MV, and three existing MAR

The advanced compressed air energy (ACAS) plant investiated operates on a partial adiabatic, partial fuel fired cycle. Only a limited advancement in state-of-the-art technology is projected for this hybrid arrangement. The A-5 hybrid systems stores the heat of compression from the low pressure and intermediate pressure compressors in a thermal energy store (TES). The heat collected in the TES is available for preheating the air from the storage cavern prior to its entering the low pressure turbine combustor. This reduces the amount of fuel consumed during power generation. The fuel heat rate for the hybrid cycle is 2660 Btu/kWh as compared to approximately 4000 Btu/kWh for a conventional CAES plant. A virtual stand-off between the hybrid plant and a conventional CAES plant at 235 mills/kWh in 1990 dollars is shown. With a lower cost and increased fuel cost projections, the hybrid system operating cost is less than that for a conventional CAES plant.

While hybrid progeny are frequently at a selective disadvantage, in some instances their increased genome size and complexity may result in greater stress resistance than their ancestors, which can be adaptively advantageous at the edges of their ancestors' ranges. While this phenomenon has been repeatedly documented in the field, the response of hybrid populations to long-term selection has not often been explored in the lab. To fill this knowledge gap we crossed the two most distantly related members of the Saccharomyces sensu stricto group, S. cerevisiae and S. uvarum, and established a mixed population of homoploid and aneuploid hybrids to study how different types of selection impact hybrid genome structure. Results As temperature was raised incrementally from 31°C to 46.5°C over 500 generations of continuous culture, selection favored loss of the S. uvarum genome, although the kinetics of genome loss differed among independent replicates. Temperature-selected isolates exhibited greater inherent and induced thermal tolerance than parental species and founding hybrids, and also exhibited ethanol resistance. In contrast, as exogenous ethanol was increased from 0% to 14% over 500 generations of continuous culture, selection favored euploid S. cerevisiae x S. uvarum hybrids. Ethanol-selected isolates were more ethanol tolerant than S. uvarum and one of the founding hybrids, but did not exhibit resistance to temperature stress. Relative to parental and founding hybrids, temperature-selected strains showed heritable differences in cell wall structure in the forms of increased resistance to zymolyase digestion and Micafungin, which targets cell wall biosynthesis. Conclusions This is the first study to show experimentally that the genomic fate of newly-formed interspecific hybrids depends on the type of selection they encounter during the course of evolution

In this work, a simple and green route to the synthesis of the bacterial nanocellulose-calcium carbonate (BNC/CaCO3) hybrid bionanocomposites using one-step in situ biosynthesis was studied. The CaCO3 was incorporated in the bacterial nanocellulose structure during the cellulose biosynthesis by Gluconacetobacter xylinus PTCC 1734 bacteria. Hestrin-Schramm (HS) and Zhou (Z) culture media were used to the hybrid bionanocomposites production and the effect of ethanol addition was investigated. Attenuated total reflection Fourier transform infrared spectroscopy, field emission scanning electron microscopy, X-ray diffraction, energy-dispersive X-ray spectroscopy, inverse gas chromatography and thermogravimetric analysis were used to characterize the samples. The experimental results demonstrated that the ethanol and culture medium play an important role in the BNC/CaCO3 hybrid bionanocomposites production, structure and properties. The BNC/CaCO3 biosynthesized in Z culture medium revealed higher O/C ratio and amphoteric surface character, which justify the highest CaCO3 content incorporation. The CaCO3 was incorporated into the cellulosic matrix decreasing the bacterial nanocellulose crystallinity. This work reveals the high potential of in situ biosynthesis of BNC/CaCO3 hybrid bionanocomposites and opens a new way to the high value-added applications of bacterial nanocellulose.

Leaf explants from field grown F1 hybrids of Lycopersicon esculentum, namely Bornia and Royesta were cultured on MS media containing 5 x 5 diallelic combinations of IAA and Kin at 0, 4, 8, 12 and 16 micro M/l each. Callogenesis, root and shoot regeneration potential of these hybrids were compared on these hormonal regimes. Royesta exhibited better callogenesis response (85%) than Bornia (72%). However, callogenesis on a given hormonal regime was genotype dependant. Root and shoot regeneration was better in case of Bornia than in Royesta. Hybrid Bornia produced shoots much more frequently (6-14%) on many diverse hormonal regimes than Royesta which produced shoots only rarely (5%) on a single hormonal regime. (author)

Investment timing under hybrid stochastic and local volatility

Kim, Jeong-Hoon; Lee, Min-Ku; Sohn, So Young

2014-01-01

Highlights: • The effects of hybrid stochastic volatility on real option prices are studied. • The stochastic volatility consists of a fast mean-reverting component and a CEV type one. • A fast mean-reverting factor lowers real option prices and investment thresholds. • The increase of elasticity raises real option prices and investment thresholds. • The effects of the addition of a slowly varying factor depend upon the project value. - Abstract: We consider an investment timing problem under a real option model where the instantaneous volatility of the project value is given by a combination of a hidden stochastic process and the project value itself. The stochastic volatility part is given by a function of a fast mean-reverting process as well as a slowly varying process and the local volatility part is a power (the elasticity parameter) of the project value itself. The elasticity parameter controls directly the correlation between the project value and the volatility. Knowing that the project value represents the market price of a real asset in many applications and the value of the elasticity parameter depends on the asset, the elasticity parameter should be treated with caution for investment decision problems. Based on the hybrid structure of volatility, we investigate the simultaneous impact of the elasticity and the stochastic volatility on the real option value as well as the investment threshold

HYBRID EDUCATION: THE ESTIMATION IN THE CATEGORIES OF INFORMATION-AXIOLOGICAL APPROACH

Directory of Open Access Journals (Sweden)

A. S. Kizilova

2018-01-01

Full Text Available Introduction: a hybrid assessment of reality is a new information-axiological level of communication between people. The term "hybrid (hybrid training" has been used as a result of the integration of digital and communication technologies in the form of online courses.Materials and methods: the main Russian forms of education are analyzed. The evaluation of the forms of education in the categories of the information-axiological approach is made on the basis of the following idea: everything is interchangeable, since everything has value. The mixing principles and models used in the process of hybrid formation are considered. Due to the fact that any mixed training requires planning, the analysis of the project and the target group, content analysis and financial analysis in this process is carried out.Results: specific educational methods are studied at the Bauman MSTU, subject to a hybrid assessment in the categories of the information-axiological approach. The analysis showed that the above explanation of the term "hybrid formation" is extremely narrow and one-sided. In particular, the search for information on volunteer education and the search for a socially-based education was conducted not only in the Bauman MSTU, but in Russia as a whole. However, the result was the portals of international student organizations with their own projects. Another example of a different interpretation of the "hybrid education" may be the assumption of quite axiologically new duties.Discussion and Conclusions: hybrid education is not limited to any temporal and territorial framework. It can manifest itself not only in the Internet-sphere, but also in the most diverse spheres of everyday life, with the interaction of various people and entire societies.

Knowledge of fish gastric emptying time is a necessary component for understanding the fish feeding rates, energy budgets and commercial production of fishes in aquaculture. The hybrid grouper Epinephelus spp. is getting popular as a culture species in Malaysia for their faster growth rate compared to commonly cultured grouper species (giant grouper Epinephelus lanceolatus and tiger grouper Epinephelus fuscoguttatus). There are data suggests that elevated sea water temperature affects gastric emptying time (GET) of fishes. Hence, this study aims to study the GET of hybrid grouper at different temperature (22, 26, 30, 34°C) in laboratory condition with commercial diet pellet. The gastric emptying times (GETs) at different temperatures were determined X-radiographically, using barium sulfate (BaSO{sub 4}) as a contrast medium food marker. The food marker and X-radiography showed that initial voidance of fecal matter began 4-6 h after feeding at all temperature. The fastest GET (13 h) was obsereved in the 30°C group, whereas the longest (17 h) GET was seen in 22°C group fed with artificial diet pellet. Not much differences in GET were recorded between the 26 and 34°C groups as 34°C groups fed lesser amount compared to 26°C groups. Nevertheless a substantial delay in GET was observed in the 22°C group. The findings of this study suggest to culture hybrid grouper between 26 to 30°C with commercial diet pellet as this temperature ranges proliferate the faster digestion process which may contribute faster growth rate of this commerical important fish species. Overall, these findings may have important consequences for optimization of commercial production of hybrid grouper.

1976-01-01

Interspecific hybridization by fusion of leaf protoplasts of Nicotiana glauca (GG) and N. langsdorffii (LL) was confirmed and extended. Enzymatic digestion of leaf tissues to obtain protoplats was followed by fusion with the aid of polyethylene glycol. The hybrid calli were selected by their better growth on defined culture media. Mature hybrid plants were identified by their morphology and tumor formation. Cytological examination revealed a range in chromosome numbers from 56 to 64 rather than the amphiploid GGLL number of 42. About 75 percent of the hybrids were fertile. The potential range in combining widely disparate genotypes by somatic cell fusion was demonstrated by fusing tobacco GGLL protoplasts with human HeLa cells. The HeLa nucleus was observed inside the plant protoplasts, thus forming an interkingdom heterokaryon.

Full Text Available Stem cells from human dental pulp have been considered as an alternative source of adult stem cells in tissue engineering because of their potential to differentiate into multiple cell lineages.Recently, polysaccharide based hydrogels have become especially attractive as matrices for the repair and regeneration of a wide variety of tissues and organs. The incorporation of inorganic minerals as hydroxyapatite nanoparticles can modulate the performance of the scaffolds with potential applications in tissue engineering. The aim of this study was to verify the osteogenic and odontogenic differentiation of dental pulp stem cells (DPSCs cultured on a carboxymethyl cellulose—hydroxyapatite hybrid hydrogel. Human DPSCs were seeded on carboxymethyl cellulose—hydroxyapatite hybrid hydrogel and on carboxymethyl cellulose hydrogel for 1, 3, 5, 7, 14 and 21 days. Cell viability assay and ultramorphological analysis were carried out to evaluate biocompatibility and cell adhesion. Real Time PCR was carried out to demonstrate the expression of osteogenic and odontogenic markers. Results showed a good adhesion and viability in cells cultured on carboxymethyl cellulose—hydroxyapatite hybrid hydrogel, while a low adhesion and viability was observed in cells cultured on carboxymethyl cellulose hydrogel. Real Time PCR data demonstrated a temporal up-regulation of osteogenic and odontogenic markers in dental pulp stem cells cultured on carboxymethyl cellulose—hydroxyapatite hybrid hydrogel. In conclusion, our in vitro data confirms the ability of DPSCs to differentiate toward osteogenic and odontogenic lineages in presence of a carboxymethyl cellulose—hydroxyapatite hybrid hydrogel. Taken together, our results provide evidence that DPSCs and carboxymethyl cellulose—hydroxyapatite hybrid hydrogel could be considered promising candidates for dental pulp complex and periodontal tissue engineering.

How can healthcare leaders build a sustainable infrastructure to leverage workforce diversity and deliver culturally and linguistically appropriate care to patients? To answer that question, two health systems participated in the National Center for Healthcare Leadership's diversity leadership demonstration project, November 2008 to December 2013. Each system provided one intervention hospital and one control hospital.The control hospital in each system participated in pre- and postassessments but received no preassessment feedback and no intervention support. Each intervention hospital's C-suite leadership and demonstration project manager worked with a diversity coach provided by the National Center for Healthcare Leadership to design and implement an action plan to improve diversity and cultural competence practices and build a sustainable infrastructure. Plans explored areas of strength and areas for improvement that were identified through preintervention assessments. The assessments focused on five competencies of strategic diversity management and culturally and linguistically appropriate care: diversity leadership, strategic human resource management, organizational climate, diversity climate, and patient cultural competence.This article describes each intervention hospital's success in action plan implementation and reports results of postintervention interviews with leadership to provide a blueprint for sustainable change.

Interspecific hybridization can generate heterosis, which is proven to be a useful tool in selective breeding programs for oyster culture. Crassostrea angulata and C. ariakensis are two important economic shellfish species in China. We conducted 2 × 2 reciprocal crosses to determine whether these two species can cross-fertilize and their hybrids can hatch, survive and perform heterosis. Fertilization was found symmetrical without delay. The rate of fertilization success of C. angulata ♀ × C. ariakensis ♂ was lower than that of C. ariakensis ♀ × C. angulata ♂, and the success rate of both hybridizations was lower than that of two intraspecific crosses each. During the planktonic period, survival rate of the progeny was lower in the hybrid crosses than in the intraspecific crosses. On day 360, mean shell height of the progeny of C. angulata ♀ × C. angulata ♂ was highest, which was followed by that of C. angulata ♀ × C. ariakensis ♂, C. ariakensis ♀ × C. ariakensis ♂ and C. ariakensis ♀ × C. angulata ♂ in a descending order. Morphology of adults produced by the hybrid crosses was similar to that of C. angulata. Both hybrids underwent normal gonad development and produced mature gametes in the mating season. This study provided new insights into the quantitative traits in interspecific crosses of Crassostrea species, thus being of guidance value for selective breeding of oyster.

Business educators have advocated that in order to build faculty's intercultural capability, it is vital to provide them with professional development in using intercultural training resources and with "community of practice" support in adapting such resources for enhancing their students' intercultural learning. This approach has been adopted in an Australian action research project titled "Internationalisation at Home" (IaH), which involved providing faculty with professional development adapted from an established intercultural training resource - the EXCELL (Excellence in Cultural Experiential Learning and Leadership) Program. In this paper, we present two case studies of the implementation of the IaH Project in business schools at the University of Canberra and at Griffith University. Lessons learned from the first study were incorporated in the design and evaluation of the second one. Faculty leaders will describe how they engage and support colleagues in adapting components of EXCELL to foster cultural inclusiveness and facilitate students' intercultural competence development. As part of project evaluation, we hypothesised that students who participated in IaH courses would report greater levels of (1) cultural inclusiveness in their educational environment, and (2) cultural learning development, compared with students who were not enrolled in IaH courses. Research participants in the Canberra case study comprised an intervention group of 140 business undergraduates enrolled in an IaH course, and a control group of 59 non-IaH undergraduates. At Griffith, participants were 211 first year management students in the intervention group and 84 students enrolled in a non-IaH first year course. In each case study, an end-of-semester survey showed that students who had completed courses with the IaH project intervention reported significantly greater levels of perceived cultural inclusiveness in multicultural classes, and of cultural learning development, than

Stability Parameters for Grain Yield and its Component Traits in Maize Hybrids of Different FAO Maturity Groups

Directory of Open Access Journals (Sweden)

2014-12-01

Full Text Available An objective evaluation of maize hybrids in intensive cropping systems requires identification not only of yield components and other agronomically important traits but also of stability parameters. Grain yield and its components were assessed in 11 maize hybrids with different lengths of growing season (FAO 300-700 maturity groups using analysis of variance and regression analysis at three different locations in Western Serbia. The test hybrids and locations showed significant differences in grain yield, grain moisture content at maturity, 1,000-kernel weight and ear length. A significant interaction was observed between all traits and the environment. The hybrids with higher mean values of the traits, regardless of maturity group, generally exhibited sensitivity i.e. adaptation to more favourable environmental conditions as compared to those having lower mean values. Regression coefficient (bi values for grain yield mostly suggested no significant differences relative to the mean. The medium-season hybrid gave high yields and less favourable values of stability parameters at most locations and in most years, as compared to mediumlate hybrids. As compared to medium-early hybrids, medium-late hybrids (FAO 600 and 700 mostly exhibited unfavourable values of stability parameters i.e. a specific response and better adaptation to favourable environmental conditions, and gave higher average yields. Apart from producing lower average yields, FAO 300 and 400 hybrids showed higher yield stability as compared to the other hybrids tested. Medium-late hybrids had higher yields and showed a better response to favourable environmental conditions compared to early-maturing hybrids. Therefore, they can be recommended for intensive cultural practices and low-stress environments. Due to their more favourable stability parameter values, medium-early hybrids can be recommended for low-intensity cultural practices and stressful environments.

Andrade, Pedro

2016-07-01

Full Text Available In this essay I will present some results of the project Public Communication of Art, which developed a seminal theory and methodology intended to cope with hybridity and new media literacy in our globalized and inter/transcultural world. Some of the methods used blend vision with touch and are called ‘hybrid methods’ or ‘hybrimethods’. Examples of these are, for instance, a Multitouch Interactive Table, a Multitouch Questionnaire, Trichotomies Game and GeoNeoLogic Novel, this last one being a hybrid novel activated by fusion of vision, touch and GPS coordinates. Another hybrimethod is a sort of discursive analysis, named Hybrid Discourse Analysis (HDA, which uses ‘semantic-logical networks’ organized by concepts and ‘relation-concepts’. HDA is here articulated with Critical Sociology and applied to the analysis of a text on Magic Realism, which is also a hybrid genre within the social field of literature.

For more than 5000 years, organic-inorganic composite materials created by men via skill and serendipity have been part of human culture and customs. The concept of ``hybrid organic-inorganic'' nanocomposites exploded in the second half of the 20th century with the expansion of the so-called ``chimie douce'' which led to many collaborations between a large set of chemists, physicists and biologists. Consequently, the scientific melting pot of these very different scientific communities created a new pluridisciplinary school of thought. Today, the tremendous effort of basic research performed in the last twenty years allows tailor-made multifunctional hybrid materials with perfect control over composition, structure and shape. Some of these hybrid materials have already entered the industrial market. Many tailor-made multiscale hybrids are increasingly impacting numerous fields of applications: optics, catalysis, energy, environment, nanomedicine, etc. In the present feature article, we emphasize several fundamental and applied aspects of the hybrid materials field: bioreplication, mesostructured thin films, Lego-like chemistry designed hybrid nanocomposites, and advanced hybrid materials for energy. Finally, a few commercial applications of hybrid materials will be presented.

To identify the presence of bacterial biofilms in nonunions comparing molecular techniques (multiplex polymerase chain reaction and mass spectrometry, fluorescent in situ hybridization) with routine intraoperative cultures. Thirty-four patients with nonunions were scheduled for surgery and enrolled in this ongoing prospective study. Intraoperative specimens were collected from removed implants, surrounding tissue membrane, and local soft tissue followed by standard culture analysis, Ibis's second generation molecular diagnostics (Ibis Biosystems), and bacterial 16S rRNA-based fluorescence in situ hybridization (FISH). Confocal microscopy was used to visualize the tissue specimens reacted with the FISH probes, which were chosen based on the Ibis analysis. Thirty-four patient encounters were analyzed. Eight were diagnosed as infected nonunions by positive intraoperative culture results. Ibis confirmed the presence of bacteria in all 8 samples. Ibis identified bacteria in a total of 30 of 34 encounters, and these data were confirmed by FISH. Twenty-two of 30 Ibis-positive samples were culture-negative. Four samples were negative by all methods of analysis. No samples were positive by culture, but negative by molecular techniques. Our preliminary data indicate that molecular diagnostics are more sensitive for identifying bacteria than cultures in cases of bony nonunion. This is likely because of the inability of cultures to detect biofilms and bacteria previously exposed to antibiotic therapy. Diagnostic Level I.

Tucci, G.; Bonora, V.; Conti, A.; Fiorini, L.

2017-08-01

Cultural heritage digitization and 3D modelling processes are mainly based on laser scanning and digital photogrammetry techniques to produce complete, detailed and photorealistic three-dimensional surveys: geometric as well as chromatic aspects, in turn testimony of materials, work techniques, state of preservation, etc., are documented using digitization processes. The paper explores the topic of 3D documentation for conservation purposes; it analyses how geomatics contributes in different steps of a restoration process and it presents an overview of different uses of 3D models for the conservation and enhancement of the cultural heritage. The paper reports on the project to digitize the earthenware frieze of the Ospedale del Ceppo in Pistoia (Italy) for 3D documentation, restoration work support, and digital and physical reconstruction and integration purposes. The intent to design an exhibition area suggests new ways to take advantage of 3D data originally acquired for documentation and scientific purposes.

The energy transition by everyone and for everyone: what potential is there for hybridization in renewable energy projects?

International Nuclear Information System (INIS)

Ruedinger, Andreas

2016-03-01

Based on an analysis of the energy transition as a collective governance issue, the notion of citizen and local buy-in has emerged as an important marker, with a view to enhance the participation of all actors in different forms. In France, this goal has been enshrined in the slogan 'the energy transition by everyone and for everyone'. In this context, the direct participation of local actors - citizens and local authorities - in the implementation of energy projects within their territories has received a great deal of attention from policy-makers. This attention is further strengthened by the more recent appetite for citizen renewable energy projects in France and lessons learned from international experiments such as in Denmark and Germany. Citizen and collaborative renewable energy models are seeing growing interest from political and industrial stakeholders, driven by an effort to promote public acceptance of these projects and redirect local savings towards transition projects. While the energy transition law explicitly calls for the promotion of innovative models, it is nevertheless necessary to have a more detailed breakdown of the numerous existing approaches. By establishing a classification based on the levels of participation in the financing and the governance of these projects, this study aims to reflect on the respective advantages and drawbacks of these models with regard to their capacity to meet the goals set out by project developers Three main types of models can be defined: projects with a conventional approach, which focus on direct financial profitability, do not include financial participation by local actors, and for which implication in the governance is limited to consultation; 'citizen' projects, which are developed around collective governance and financing managed by local actors (citizens and/or local authorities); and a variety of 'collaborative' projects, which are the outcome of different kinds of hybridization between these two

Sustainable knowledge development across cultural boundaries: Experiences from the EU-project SILMAS (Toolbox for conflict solving instruments in Alpine Lake Management)

Science.gov (United States)

Fegerl, Michael; Wieden, Wilfried

2013-04-01

Increasingly people have to communicate knowledge across cultural and language boundaries. Even though recent technologies offer powerful communication facilities people often feel confronted with barriers which clearly reduce their chances of making their interaction a success. Concrete evidence concerning such problems derives from a number of projects, where generated knowledge often results in dead-end products. In the Alpine Space-project SILMAS (Sustainable Instruments for Lake Management in Alpine Space), in which both authors were involved, a special approach (syneris® ) was taken to avoid this problem and to manage project knowledge in sustainable form. Under this approach knowledge input and output are handled interactively: Relevant knowledge can be developed continuously and users can always access the latest state of expertise. Resort to the respective tools and procedures can also assist in closing knowledge gaps and in developing innovative responses to familiar or novel problems. This contribution intends to describe possible ways and means which have been found to increase the chances of success of knowledge communication across cultural boundaries. The process of trans-cultural discussions of experts to find a standardized solution is highlighted as well as the problem of dissemination of expert knowledge to variant stakeholders. Finally lessons learned are made accessible, where a main task lies in the creation of a tool box for conflict solving instruments, as a demonstrable result of the project and for the time thereafter. The interactive web-based toolbox enables lake managers to access best practice instruments in standardized, explicit and cross-linguistic form.

The future of hybrid vehicles

Energy Technology Data Exchange (ETDEWEB)

Vangraefschepe, F.; Menegazzi, P.

2004-12-15

This new demand from the U.S. market is being taken very seriously by key players in the field. GM and Daimler Chrysler have announced an alliance for the joint development of a hybrid vehicle scheduled to reach the market by 2007. Development projects of this type will require capital investment of several hundred million dollars over the period. Given that it is now imperative to cut greenhouse gas emissions, the hybrid vehicle offers a credible alternative. It is already on the market, despite the constraints inherent to a configuration combining an electric motor and an internal combustion engine, and despite the added cost. The technical choices are complex and varied, depending on the objectives: potential CO{sub 2} emissions gains range from a few percentage points to over 45%, depending on the engine/motor architecture. The gasoline hybrid vehicle is emerging as an alternative to the diesel engine, especially in Japan and the United States, but its growth will depend on the ability of the motor industry to reduce the added cost.

Importance of including cultural practices in ecological restoration.

Wehi, Priscilla M; Lord, Janice M

Ecosystems worldwide have a long history of use and management by indigenous cultures. However, environmental degradation can reduce the availability of culturally important resources. Ecological restoration aims to repair damage to ecosystems caused by human activity, but it is unclear how often restoration projects incorporate the return of harvesting or traditional life patterns for indigenous communities. We examined the incorporation of cultural use of natural resources into ecological restoration in the context of a culturally important but protected New Zealand bird; among award-winning restoration projects in Australasia and worldwide; and in the peer-reviewed restoration ecology literature. Among New Zealand's culturally important bird species, differences in threat status and availability for hunting were large. These differences indicate the values of a colonizing culture can inhibit harvesting by indigenous people. In Australasia among award-winning ecological restoration projects, restored areas beyond aesthetic or recreational use, despite many projects encouraging community participation. Globally, restoration goals differed among regions. For example, in North America, projects were primarily conservation oriented, whereas in Asia and Africa projects frequently focused on restoring cultural harvesting. From 1995 to 2014, the restoration ecology literature contained few references to cultural values or use. We argue that restoration practitioners are missing a vital component for reassembling functional ecosystems. Inclusion of sustainably harvestable areas within restored landscapes may allow for the continuation of traditional practices that shaped ecosystems for millennia, and also aid project success by ensuring community support. © 2017 Society for Conservation Biology.

BROWN, BLACK, YELLOW, WHITE: FILIPINO MUSICIANSHIP IN HONG KONG AND THEIR HYBRIDIZED SOCIABILITY

Directory of Open Access Journals (Sweden)

Lee William Watkins

2010-06-01

Full Text Available This article addresses the issue of hybridity as one manifested in the everyday experiences of migrant Filipino musicians in Hong Kong, with a particular emphasis on their differences in a dialectic of the self and other as mobilised in performance, and, as a continuum woven into their racial colour and various social statuses. Where hybridity in music is the concern, most studies focus on hybridity as a matter of aesthetics, while in nonmusical areas, hybridity is addressed in the context of the relationship between colonized and colonizer during western imperialism, and between migrant and host in the contemporary age. This article combines these two areas: it will briefly include, but also move beyond the concern with aesthetics and propose hybridity through the cultural analysis of musical performance more as a form of social action resulting from colonialism, neocolonialism and transnationalism.

F1 hybrids can outperform their parents in yield and vegetative biomass, features of hybrid vigor that form the basis of the hybrid seed industry. The yield advantage of the F1 is lost in the F2 and subsequent generations. In Arabidopsis, from F2 plants that have a F1-like phenotype, we have by recurrent selection produced pure breeding F5/F6 lines, hybrid mimics, in which the characteristics of the F1 hybrid are stabilized. These hybrid mimic lines, like the F1 hybrid, have larger leaves than the parent plant, and the leaves have increased photosynthetic cell numbers, and in some lines, increased size of cells, suggesting an increased supply of photosynthate. A comparison of the differentially expressed genes in the F1 hybrid with those of eight hybrid mimic lines identified metabolic pathways altered in both; these pathways include down-regulation of defense response pathways and altered abiotic response pathways. F6 hybrid mimic lines are mostly homozygous at each locus in the genome and yet retain the large F1-like phenotype. Many alleles in the F6 plants, when they are homozygous, have expression levels different to the level in the parent. We consider this altered expression to be a consequence of transregulation of genes from one parent by genes from the other parent. Transregulation could also arise from epigenetic modifications in the F1. The pure breeding hybrid mimics have been valuable in probing the mechanisms of hybrid vigor and may also prove to be useful hybrid vigor equivalents in agriculture. PMID:26283378

This report summarizes the US Department of Energy's (DOE) cultural resource studies that were undertaken in support of the DOE's Uranium Mill Tailings Remedial Action (UMTRA) Project in the state of Colorado for the period of October 1, 1991, through September 30, 1992. This report fulfills the DOE's obligation to provide an annual report to the state of Colorado on the status and results of cultural resource studies conducted during the above period of record. This requirement is stated in a programmatic memorandum of agreement executed between the DOE, the Advisory Council on Historic Preservation, and the Colorado State Historic Preservation Officer in December 1984. Previous reports were based on a calendar year reporting period. However, in order to be more consistent with the programmatic memorandum of agreement, the period of record for this and subsequent annual reports has been changed to the Federal fiscal year. The current status and summaries of 1992 cultural resource surveys are provided for all UMTRA Project sites in Colorado. The sites are Durango, Grand Junction, Gunnison, Maybell, Naturita, Rifle, and Slick Rock

This paper presents the integrated methods using UAVs and geodetic techniques to monitor ground deformation within the Choirokoitia UNESCO World Heritage Site in Cyprus. The Neolithic settlement of Choirokoitia, occupied from the 7th to the 4th millennium B.C., is one of the most important prehistoric sites in the eastern Mediterranean. The study is conducted under the PROTHEGO (PROTection of European Cultural HEritage from GeO-hazards) project, which is a collaborative research project funded in the framework of the Joint Programming Initiative on Cultural Heritage and Global Change (JPICH) - Heritage Plus in 2015-2018 (www.prothego.eu) and through the Cyprus Research Promotion Foundation. PROTHEGO aims to make an innovative contribution towards the analysis of geo-hazards in areas of cultural heritage, and uses novel space technology based on radar interferometry to retrieve information on ground stability and motion in the 400+ UNESCO's World Heritage List monuments and sites of Europe. The field measurements collected at the Choirokoitia site will be later compared with SAR data to verify micro-movements in the area to monitor potential geo-hazards. The site is located on a steep hill, which makes it vulnerable to rock falls and landslides.

The Missing Hybridity: ‘Envisioning’ Ukrainian Literary Space

Directory of Open Access Journals (Sweden)

Marco Puleri

2015-05-01

Full Text Available In this paper, the author focuses on the question concerning the complex positioning of the Russophone literary phenomenon in the Ukrainian post-Soviet literary canon. Analysing the conceptualization of the hybrid cultural elements in the post-Soviet cultural area, it is possible to observe the rise of a contrast between the cultural ‘exclusivist’ and ‘inclusivist’ attitudes in the Ukrainian literary debate. It is the product of the renewed social and political clash between the Ukrainian and Russian ‘national systems’. The ideologization of the ethnolinguistic factor in the Post-Soviet area gives birth to competing ideologies, which draw new ‘imagined borders’ in the Ukrainian literary space. It is the result of the polarization of the respective national historical narratives, misused by the current political discourses, to paralyse the dialogical perspectives in the process of cultural confrontation. Listening to the ‘voices’ of contemporary cultural actors, it will be possible to draw different images in order to envision the Ukrainian literary space.

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

Directory of Open Access Journals (Sweden)

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.

Multimode Resource-Constrained Multiple Project Scheduling Problem under Fuzzy Random Environment and Its Application to a Large Scale Hydropower Construction Project

Science.gov (United States)

Xu, Jiuping

2014-01-01

This paper presents an extension of the multimode resource-constrained project scheduling problem for a large scale construction project where multiple parallel projects and a fuzzy random environment are considered. By taking into account the most typical goals in project management, a cost/weighted makespan/quality trade-off optimization model is constructed. To deal with the uncertainties, a hybrid crisp approach is used to transform the fuzzy random parameters into fuzzy variables that are subsequently defuzzified using an expected value operator with an optimistic-pessimistic index. Then a combinatorial-priority-based hybrid particle swarm optimization algorithm is developed to solve the proposed model, where the combinatorial particle swarm optimization and priority-based particle swarm optimization are designed to assign modes to activities and to schedule activities, respectively. Finally, the results and analysis of a practical example at a large scale hydropower construction project are presented to demonstrate the practicality and efficiency of the proposed model and optimization method.

Mendes, Ana C; Gorzelanny, Christian; Halter, Natalia; Schneider, Stefan W; Chronakis, Ioannis S

2016-08-20

Chitosan (Ch) polysaccharide was mixed with phospholipids (P) to generate electrospun hybrid nanofibers intended to be used as platforms for transdermal drug delivery. Ch/P nanofibers exibithed average diameters ranging from 248±94nm to 600±201nm, depending on the amount of phospholipids used. Fourier Transformed Infra-Red (FTIR) spectroscopy and Dynamic Light Scattering (DLS) data suggested the occurrence of electrostatic interactions between amine groups of chitosan with the phospholipid counterparts. The nanofibers were shown to be stable for at least 7days in Phosphate Buffer Saline (PBS) solution. Cytotoxicity studies (WST-1 and LDH assays) demonstrated that the hybrid nanofibers have suitable biocompatibility. Fluorescence microscopy, also suggested that L929 cells seeded on top of the CH/P hybrid have similar metabolic activity comparatively to the cells seeded on tissue culture plate (control). The release of curcumin, diclofenac and vitamin B12, as model drugs, from Ch/P hybrid nanofibers was investigated, demonstrating their potential utilization as a transdermal drug delivery system.

Sandberg, J. J.

1980-01-01

Phase I of the Near-Term Hybrid Vehicle Program involved the development of preliminary designs of electric/heat engine hybrid passenger vehicles. The preliminary designs were developed on the basis of mission analysis, performance specification, and design trade-off studies conducted independently by four contractors. THe resulting designs involve parallel hybrid (heat engine/electric) propulsion systems with significant variation in component selection, power train layout, and control strategy. Each of the four designs is projected by its developer as having the potential to substitute electrical energy for 40% to 70% of the petroleum fuel consumed annually by its conventional counterpart.

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.

Evaluation of Posterolateral Lumbar Fusion in Sheep Using Mineral Scaffolds Seeded with Cultured Bone Marrow Cells

2014-12-01

Full Text Available The objective of this study is to investigate the efficacy of hybrid constructs in comparison to bone grafts (autograft and allograft for posterolateral lumbar fusion (PLF in sheep, instrumented with transpedicular screws and bars. Hybrid constructs using cultured bone marrow (BM mesenchymal stem cells (MSCs have shown promising results in several bone healing models. In particular, hybrid constructs made by calcium phosphate-enriched cells have had similar fusion rates to bone autografts in posterolateral lumbar fusion in sheep. In our study, four experimental spinal fusions in two animal groups were compared in sheep: autograft and allograft (reference group, hydroxyapatite scaffold, and hydroxyapatite scaffold seeded with cultured and osteoinduced bone marrow MSCs (hybrid construct. During the last three days of culture, dexamethasone (dex and beta-glycerophosphate (β-GP were added to potentiate osteoinduction. The two experimental situations of each group were tested in the same spinal segment (L4–L5. Spinal fusion and bone formation were studied by clinical observation, X-ray, computed tomography (CT, histology, and histomorphometry. Lumbar fusion rates assessed by CT scan and histology were higher for autograft and allograft (70% than for mineral scaffold alone (22% and hybrid constructs (35%. The quantity of new bone formation was also higher for the reference group, quite similar in both (autograft and allograft. Although the hybrid scaffold group had a better fusion rate than the non-hybrid scaffold group, the histological analysis revealed no significant differences between them in terms of quantity of bone formation. The histology results suggested that mineral scaffolds were partly resorbed in an early phase, and included in callus tissues. Far from the callus area the hydroxyapatite alone did not generate bone around it, but the hybrid scaffold did. In nude mice, labeled cells were induced to differentiate in vivo and monitored

Amamentação: um híbrido natureza-cultura Breastfeeding: a nature-culture hybrid

mudanças correspondem a uma revalorização da biologia e a um aprofundamento nos processos interdisciplinares.OBJECTIVE: To contribute to the creation of a new theoretical synthesis about the relationship between the biological and social dimensions of breastfeeding, categorizing it as a nature-nurture hybrid. SOURCES OF DATA: The methodological approach of the present article was based on the qualitative health research frame, and data were analyzed on the basis of dialectic-hermeneutic principles. Primary sources, comprising historical documents, books, scientific articles and medical theses written in the 19th and 20th centuries were analyzed. SUMMARY OF THE FINDINGS: Depending on the moment in history and on the expectations that surround the act of breastfeeding, the aspects related to nature and nurture, i.e., to biology and society, sometimes separate out and sometimes intermingle. A comprehensive approach to breastfeeding makes possible to see that it had to be considered instinctive, natural and biological in order to be assimilated as a cultural habit, and thus, it is not open to any kind of questioning. On other occasions, particularly in the course of the past decade, there has been a steady tendency to supplant traditional biological reductionism, which yielded cultural interpretations that do not reduce the human being to the status of a mammal like any other. Under this point of view, breastfeeding, in addition to being biologically determined, is socially conditioned, and thus constitutes an act embedded in ideologies and determinants resulting from the concrete conditions of life. In real life, however, a process apparently so natural, so loaded with affection and emotion is, in fact, affected by the most aggressive market interests, very often presented as scientific knowledge and decked out as health provisions. CONCLUSION: Breastfeeding focused as a nature-culture hybrid symbolizes the theoretical and methodological changes in the field, especially

HOP-X aimed to combine the advantages of nanotechnology and organic electronics for application in medical X-ray imaging in order to enable more cost-effective imaging at lower dose. Solution-processing of organic semiconductors enables easy hybridization with X-ray absorbers and processing on large areas. In this project, nano-sized scintillators and quantum dots have been synthesized and characterized as X-ray absorbers. Organic semiconductor materials have been identified which allow charge carrier extraction from layers with a thickness of up to 200 μm. Hybrid-organic photodiodes have been processed and the ideal mixture of organic semiconductor and inorganic X-ray absorber was determined. This mixture provide a high X-ray absorption and an efficient charge carrier extraction at the same time. Photodiodes have been integrated on TFT-matrix backplanes in order to demonstrate the concept in X-ray imagers.

Integrating climate change criteria in reforestation projects using a hybrid decision-support system

Curiel-Esparza, Jorge; Gonzalez-Utrillas, Nuria; Canto-Perello, Julian; Martin-Utrillas, Manuel

2015-09-01

The selection of appropriate species in a reforestation project has always been a complex decision-making problem in which, due mostly to government policies and other stakeholders, not only economic criteria but also other environmental issues interact. Climate change has not usually been taken into account in traditional reforestation decision-making strategies and management procedures. Moreover, there is a lack of agreement on the percentage of each one of the species in reforestation planning, which is usually calculated in a discretionary way. In this context, an effective multicriteria technique has been developed in order to improve the process of selecting species for reforestation in the Mediterranean region of Spain. A hybrid Delphi-AHP methodology is proposed, which includes a consistency analysis in order to reduce random choices. As a result, this technique provides an optimal percentage distribution of the appropriate species to be used in reforestation planning. The highest values of the weight given for each subcriteria corresponded to FR (fire forest response) and PR (pests and diseases risk), because of the increasing importance of the impact of climate change in the forest. However, CB (conservation of biodiversitiy) was in the third position in line with the aim of reforestation. Therefore, the most suitable species were Quercus faginea (19.75%) and Quercus ilex (19.35%), which offer a good balance between all the factors affecting the success and viability of reforestation.

A Hybrid Life-Cycle Assessment of Nonrenewable Energy and Greenhouse-Gas Emissions of a Village-Level Biomass Gasification Project in China

Directory of Open Access Journals (Sweden)

2012-07-01

Full Text Available Small-scale bio-energy projects have been launched in rural areas of China and are considered as alternatives to fossil-fuel energy. However, energetic and environmental evaluation of these projects has rarely been carried out, though it is necessary for their long-term development. A village-level biomass gasification project provides an example. A hybrid life-cycle assessment (LCA of its total nonrenewable energy (NE cost and associated greenhouse gas (GHG emissions is presented in this paper. The results show that the total energy cost for one joule of biomass gas output from the project is 2.93 J, of which 0.89 J is from nonrenewable energy, and the related GHG emission cost is 1.17 × 10⁻⁴ g CO₂-eq over its designed life cycle of 20 years. To provide equivalent effective calorific value for cooking work, the utilization of one joule of biomass gas will lead to more life cycle NE cost by 0.07 J and more GHG emissions by 8.92 × 10⁻⁵ g CO₂-eq compared to natural gas taking into consideration of the difference in combustion efficiency and calorific value. The small-scale bio-energy project has fallen into dilemma, i.e., struggling for survival, and for a more successful future development of village-level gasification projects, much effort is needed to tide over the plight of its development, such as high cost and low efficiency caused by decentralized construction, technical shortcomings and low utilization rate of by-products.

Open Source Hbim for Cultural Heritage: a Project Proposal

Science.gov (United States)

Diara, F.; Rinaudo, F.

2018-05-01

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.

Large construction projects involve the functioning of a complex activity system (AS) in network format. Anomalies such as accidents, delays, reworks, etc., can be explained by contradictions that emerge historically in the system. The aim of this study was to analyze the history of an airport construction project to understand the current contradictions and anomalies in the AS and how they emerged. A case study was conducted for this purpose, combining Collective Work Analysis, interviews, observations, and analysis of documents that provided the basis for sessions in the Change Laboratory, where a participant timeline was elaborated with the principal events during the construction project. Based on the timeline, a historical analysis of the airport's AS revealed critical historical events and contradictions that explained the anomalies that occurred during the project. The analysis showed that the airport had been planned for construction with politically determined deadlines that were insufficient and inconsistent with the project's complexity. The choice of the contract modality, which assigned responsibility to a joint venture for all of the project's phases, was another critical historical event, because it allowed launching the construction before a definitive executive project had been drafted. There were also different cultures in companies working together for the first time in the context of a project with time pressures and outsourcing of activities without the necessary coordination. Identifying these contradictions and their historical origins proved essential for understanding the current situation and efforts to prevent similar situations in the future.

2006-11-01

Full Text Available The aim of this research is to develop an operational ‘project management culture’ framework, which can be used by project managers and organisations to support project work. One of the main causes of project failure is attributed to a non-supportive project management culture in organisations. A triangulation method is followed inclusive of a thorough literature review, a survey questionnaire and a concept mapping process. A project management culture framework with descriptive elements, based on Deal and Kennedy’s (1982 definition of organisational culture, comprising of four dimensions i.e. project process; people in projects; project systems and structure, and project environment was developed.

Full Text Available This article deals with the hybridity of contemporary Agusan Manobo music as evident in its repertory and in the heteroglossia of possession ritual performances, where various archaic and modern speech styles (including song and ritual dance music co-exist. This hybridity is consequent to the history of Agusan Manobo relations with outsiders, especially Visayan-speaking settlers whose markers of group identity have been incorporated into Manobo rites. Such incorporation indicates the Manobo presence to a social world that is characterized by a mix between inland Manobo and coastal Visayan cultures.

Building America Case Study: Assessment of a Hybrid Retrofit Gas Water Heater

Energy Technology Data Exchange (ETDEWEB)

2017-06-19

This project completed a modeling evaluation of a hybrid gas water heater that combines a reduced capacity tankless unit with a downsized storage tank. This product would meet a significant market need by providing a higher efficiency gas water heater solution for retrofit applications while maintaining compatibility with the half-inch gas lines and standard B vents found in most homes. The TRNSYS simulation tool was used to model a base case 0.60 EF atmospheric gas storage water, a 0.82 EF non-condensing gas tankless water heater, an existing (high capacity) hybrid unit on the market, and an alternative hybrid unit with lower storage volume and reduced gas input requirements. Simulations were completed under a 'peak day' sizing scenario with 183 gpd hot water loads in a Minnesota winter climate case. Full-year simulations were then completed in three climates (ranging from Phoenix to Minneapolis) for three hot water load scenarios (36, 57, and 96 gpd). Model projections indicate that the alternative hybrid offers an average 4.5% efficiency improvement relative to the 0.60 EF gas storage unit across all scenarios modeled. The alternative hybrid water heater evaluated does show promise, but the current low cost of natural gas across much of the country and the relatively small incremental efficiency improvement poses challenges in initially building a market demand for the product.

Polemological Paradigm of Hybrid War Research

Directory of Open Access Journals (Sweden)

Roman Dodonov

2017-09-01

Full Text Available This article is devoted to the methodological problems and manipulative mechanisms of hybrid warfare. Owing to the polemological (from πολέμιος — war and λόγος — study approach the authors managed to systematize and summarize the theories of war and peace, clarify contemporary western concepts of warfare, outline the specifi cs of the Russian view on the hybrid war concept, assess the signifi cance of information and manipulation technologies for hybrid wars, analyze a number of geopolitical and socio-cultural dimensions of modern hybrid wars. The polemology is a branch of science, which studies the nature of armed confl icts and wars, their role in time and space, cycles, intensity, scope, scale, and causative relations and their classifi cation. Polemology deals with the wars and armed confl icts of the past, present and future. Novel hybrid wars take a respective place among them. They involve using all available warfare, regular and irregular, cyber and those allowing for the use of weapons of mass destruction, and also information, psychological and propaganda war using the latest information and media technologies. According to the classical approach, the state is the only subject of military actions, but today its role has changed dramatically under the infl uence of other political and economic supranational and trans-border factors. For the purpose of studying wars and armed confl icts from the polemological perspective it means the need to focus on social changes in all the areas of human life, on considering various elements of the political, economic or even technological context, which infl uence the war as a social phenomenon.

This paper is the outcome of a small scale hybrid energy generator (hydro and photovoltaic) project. It contains the photovoltaics part of the project. The demand of energy resources is increasing day by day. That is why people nowadays tend to move on and changes their energy usage from using fossil fuels to a cleaner and green energy like hydro energy, solar energy etc. Nevertheless, energy is hard to come by for people who live in remote areas and also campsites in the remote areas which need continuous energy sources to power the facilities. Thus, the purpose of this project is to design and develop a small scale hybrid energy generator to help people that are in need of power. This main objective of this project is to develop and analyze the effectiveness of solar trackers in order to increase the electricity generation from solar energy. Software like Solidworks and Arduino is used to sketch and construct the design and also to program the microcontroller respectively. Experimental results show the effectiveness of the designed solar tracker sytem.

Near-term hybrid vehicle program, phase 1. Appendix D: Sensitivity analysis resport

Science.gov (United States)

1979-01-01

Parametric analyses, using a hybrid vehicle synthesis and economics program (HYVELD) are described investigating the sensitivity of hybrid vehicle cost, fuel usage, utility, and marketability to changes in travel statistics, energy costs, vehicle lifetime and maintenance, owner use patterns, internal combustion engine (ICE) reference vehicle fuel economy, and drive-line component costs and type. The lowest initial cost of the hybrid vehicle would be $1200 to $1500 higher than that of the conventional vehicle. For nominal energy costs ($1.00/gal for gasoline and 4.2 cents/kWh for electricity), the ownership cost of the hybrid vehicle is projected to be 0.5 to 1.0 cents/mi less than the conventional ICE vehicle. To attain this ownership cost differential, the lifetime of the hybrid vehicle must be extended to 12 years and its maintenance cost reduced by 25 percent compared with the conventional vehicle. The ownership cost advantage of the hybrid vehicle increases rapidly as the price of fuel increases from $1 to $2/gal.

The HPDP has successfully conducted four tests of the 250,000 pound thrust hybrid rocket motor at NASA's Stennis Space Center. This paper documents the test series.

Personal Rotorcraft Design and Performance with Electric Hybridization

Science.gov (United States)

Snyder, Christopher A.

2017-01-01

Recent and projected improvements for more or all-electric aviation propulsion systems can enable greater personal mobility, while also reducing environmental impact (noise and emissions). However, all-electric energy storage capability is significantly less than present, hydrocarbon-fueled systems. A system study was performed exploring design and performance assuming hybrid propulsion ranging from traditional hydrocarbon-fueled cycles (gasoline Otto and diesel) to all-electric systems using electric motors generators, with batteries for energy storage and load leveling. Study vehicles were a conventional, single-main rotor (SMR) helicopter and an advanced vertical takeoff and landing (VTOL) aircraft. Vehicle capability was limited to two or three people (including pilot or crew); the design range for the VTOL aircraft was set to 150 miles (about one hour total flight). Search and rescue (SAR), loiter, and cruise-dominated missions were chosen to illustrate each vehicle and degree of hybrid propulsion strengths and weaknesses. The traditional, SMR helicopter is a hover-optimized design; electric hybridization was performed assuming a parallel hybrid approach by varying degree of hybridization. Many of the helicopter hybrid propulsion combinations have some mission capabilities that might be effective for short range or on-demand mobility missions. However, even for 30 year technology electrical components, all hybrid propulsion systems studied result in less available fuel, lower maximum range, and reduced hover and loiter duration than the baseline vehicle. Results for the VTOL aircraft were more encouraging. Series hybrid combinations reflective of near-term systems could improve range and loiter duration by 30. Advanced, higher performing series hybrid combinations could double or almost triple the VTOL aircrafts range and loiter duration. Additional details on the study assumptions and work performed are given, as well as suggestions for future study effort.

Impact strength on fiber-reinforced hybrid composite

Firdaus, S M; Nurdina; Ariff, M Azmil

2013-01-01

Acrylonitrile-Butadiene-Styrene (ABS) has been well known composite in automotive players to have light weight with high impact strength material compared to sheet metal material which has high impact strength but heavy in weight. In this project, the impact strength properties of fabricated pure ABS were compared to the eight samples of hybrid ABS composite with different weight percentages of short fibers and particle sizes of ground rubber. The objective was to improve the impact strength in addition of short fibers and ground rubber particles. These samples were then characterized using an un-notched Izod impact test. Results show that the increasing of filler percentage yielded an adverse effect on the impact strength of the hybrid composite. The effect of the ground rubber particulate sizes however are deemed to be marginal than the effect of varying filler percentage based on the collected impact strength data from all physically tested hybrid composites

As a result of the rising requirements on the development process of modern vehicles, simulation models for the prediction of fuel efficiency have become an irreplaceable tool in the automotive industry. Especially for the design of hybrid electric drivetrains, the increasingly short development cycles can only be met by the use of efficient simulation models. At the IVK of the University of Stuttgart, different approaches to simulating the longitudinal dynamics of hybrid electric vehicles were analysed and compared within the presented project. The focus of the investigations was on urban operation. The objective was to develop a hybrid vehicle concept that allows an equitable comparison with pure battery electric vehicles. (orig.)

A considerable body of research cross-culturally examines the evolution of religious traditions, beliefs and behaviors. The bulk of this research, however, draws from coded qualitative ethnographies rather than from standardized methods specifically designed to measure religious beliefs and behaviors. Psychological data sets that examine religious thought and behavior in controlled conditions tend to be disproportionately sampled from student populations. Some cross-national databases employ standardized methods at the individual level, but are primarily focused on fully market integrated, state-level societies. The Evolution of Religion and Morality Project sought to generate a data set that systematically probed individual level measures sampling across a wider range of human populations. The set includes data from behavioral economic experiments and detailed surveys of demographics, religious beliefs and practices, material security, and intergroup perceptions. This paper describes the methods and variables, briefly introduces the sites and sampling techniques, notes inconsistencies across sites, and provides some basic reporting for the data set.

Complex and multiple barriers confront out-patient programs in promoting recovery and addressing mental health recipients' work-related goals. This article describes a focused organizational change project utilizing intensive consultation and technical assistance within five New York City outpatient psychiatric services. The project aimed to increase staff exposure to, understanding and use of work-related and recovery-based concepts to promote consumers' recovery and attainment of employment goals. Tailored assessment, curriculum delivery, and identification and implementation of change objectives were useful strategies in promoting change. This change model can serve to assist programs in their efforts to integrate new approaches and to better understand changes among leadership, staff and consumers, and changes in organizational culture and practice required to support a work and recovery-oriented service paradigm. The project experience suggests that adopting and embracing new practices takes time. Varied and incremental steps toward programmatic and operational changes can be significant and can reap authentic sustainable change occurring in the process of learning, experiencing, internalizing and adjusting to new methods of practice.

da Silva, Isaias; Horikawa, Oswaldo; Cardoso, Jose R; Camargo, Fernando A; Andrade, Aron J P; Bock, Eduardo G P

2011-05-01

In previous studies, we presented main strategies for suspending the rotor of a mixed-flow type (centrifugal and axial) ventricular assist device (VAD), originally presented by the Institute Dante Pazzanese of Cardiology (IDPC), Brazil. Magnetic suspension is achieved by the use of a magnetic bearing architecture in which the active control is executed in only one degree of freedom, in the axial direction of the rotor. Remaining degrees of freedom, excepting the rotation, are restricted only by the attraction force between pairs of permanent magnets. This study is part of a joint project in development by IDPC and Escola Politecnica of São Paulo University, Brazil. This article shows advances in that project, presenting two promising solutions for magnetic bearings. One solution uses hybrid cores as electromagnetic actuators, that is, cores that combine iron and permanent magnets. The other solution uses actuators, also of hybrid type, but with the magnetic circuit closed by an iron core. After preliminary analysis, a pump prototype has been developed for each solution and has been tested. For each prototype, a brushless DC motor has been developed as the rotor driver. Each solution was evaluated by in vitro experiments and guidelines are extracted for future improvements. Tests have shown good results and demonstrated that one solution is not isolated from the other. One complements the other for the development of a single-axis-controlled, hybrid-type magnetic bearing for a mixed-flow type VAD. © 2011, Copyright the Authors.

A novel biodegradable nano/micro hybrid structure was obtained by electrospinning P3HB or PCL nanofibers onto a twisted silk fibroin (SF) structure, with the aim of fabricating a suitable scaffold for tendon and ligament tissue engineering. The electrospinning (ES) processing parameters for P3HB and PCL were optimized on 2D samples, and applied to produce two different nano/micro hybrid constructs (SF/ES-PCL and SF/ES-P3HB).Morphological, chemico-physical and mechanical properties of the novel hybrid scaffolds were evaluated by SEM, ATR FT-IR, DSC, tensile and thermodynamic mechanical tests. The results demonstrated that the nanofibers were tightly wrapped around the silk filaments, and the crystallinity of the SF twisted yarns was not influenced by the presence of the electrospun polymers. The slightly higher mechanical properties of the hybrid constructs confirmed an increase of internal forces due to the interaction between nano and micro components. Cell culture tests with L929 fibroblasts, in the presence of the sample eluates or in direct contact with the hybrid structures, showed no cytotoxic effects and a good level of cytocompatibility of the nano/micro hybrid structures in term of cell viability, particularly at day 1. Cell viability onto the nano/micro hybrid structures decreased from the first to the third day of culture when compared with the control culture plastic, but appeared to be higher when compared with the uncoated SF yarns. Although additional in vitro and in vivo tests are needed, the original fabrication method here described appears promising for scaffolds suitable for tendon and ligament tissue engineering.

Growth and biomass components of four poplar clones were studied during four consecutive years of short-rotation culture in western Washington, U.S.A. Results confirmed previous observations indicating the high productive potential of hybrid clones. In two of the hybrid clones tested, large differences in biomass distribution among tree components and in the pattern of growth were evident, as indicated by harvest index and root/shoot ratios. Results suggest that the clonal differences shown in total biomass, in allocation to different tree components, and in harvest index, have important implications for future poplar breeding programs. 39 refs., 4 tabs., 4 figs.

Porous and pliable conduits made of biodegradable polymeric scaffolds offer great potential for the development of blood vessel substitutes but they generally lack signals for cell proliferation, survival and maintenance of a normal phenotype. In this study we have prepared and evaluated porous poly({epsilon}-caprolactone) (PCL) integrated with fibrin composite (FC) to get a biomimetic hybrid scaffold (FC PCL) with the biological properties of fibrin, fibronectin (FN), gelatin, growth factors and glycosaminoglycans. Reduced platelet adhesion on a human umbilical vein endothelial cell-seeded hybrid scaffold as compared to bare PCL or FC PCL was observed, which suggests the non-thrombogenic nature of the tissue-engineered scaffold. Analysis of real-time polymerase chain reaction (RT-PCR) after 5 days of endothelial cell (EC) culture on a hybrid scaffold indicated that the prothrombotic von Willebrand factor and plasminogen activator inhibitor (PAI) were quiescent and stable. Meanwhile, dynamic expressions of tissue plasminogen activator (tPA) and endothelial nitric oxide synthase indicated the desired cell phenotype on the scaffold. On the hybrid scaffold, shear stress could induce enhanced nitric oxide release, which implicates vaso-responsiveness of EC grown on the tissue-engineered construct. Significant upregulation of mRNA for extracellular matrix (ECM) proteins, collagen IV and elastin, in EC was detected by RT-PCR after growing them on the hybrid scaffold and FC-coated tissue culture polystyrene (FC TCPS) but not on FN-coated TCPS. The results indicate that the FC PCL hybrid scaffold can accomplish a remodeled ECM and non-thrombogenic EC phenotype, and can be further investigated as a scaffold for cardiovascular tissue engineering.

The history of fusion-fission hybrid systems based on a tokamak device as an extremely efficient DT-fusion neutron source has passed through several periods of ample research activity in the world since the very beginning of fusion research in the 1950s. Recently, a new roadmap of the hybrid program has been proposed with the goal to build a pilot hybrid plant (PHP) in Russia by 2030. Development of the DEMO-FNS tokamak for fusion and hybrid technologies, which is planned to be built by 2023, is the key milestone on the path to the PHP. This facility is in the phase of conceptual design aimed at providing feasibility studies for a full set of steady state tokamak technologies at a fusion energy gain factor Q ˜ 1, fusion power of ˜40 MW and opportunities for testing a wide range of hybrid technologies with the emphasis on continuous nuclide processing in molten salts. This paper describes the project motivations, its current status and the key issues of the design.

Conventional breeding and plant improvement increasingly become inadequate to keep up with progression and high quality demands. Thus biotechnological techniques are more and more adopted. Initially, biotechnological tools have supported conventional breeding by in vitro culture techniques......, comprising micropropagation, speeding up multiplication and improving uniformity. Also, crossing barriers of incompatible plants have been overcome using in vitro methods and embryo rescue techniques in wide hybridization approaches. Marker-assisted breeding is employed for targeted selection of DNA...... fragments from parental plants in respect to identification of desired characteristics in offspring or among hybrid plants. Phylogeny-assisted breeding and knowledge about genetic relationships support the ability to develop new hybrids. Finally, chemical and radiation induced mutagenesis are established...

INDIAN CUISINE AS A PASSING LINK FROM "CULTURE" TO "NATURE": INVERTING LÉVI-STRAUSS

Directory of Open Access Journals (Sweden)

Full Text Available According to Claude Lévi-Strauss, the cuisine constitutes a passing link from stage of nature to stage of culture. Based on ethnographic research among the Mbyá-Guarani, this article analyzes this assertion under the light of the Amerindian cosmology. However, the dichotomy between nature and culture does not apply to indigenous groups, since for these nature and culture constitute a hybrid. To this hybridism might also be added the domain of supernatural. In terms of analysis this hybrid configuration does not allow any kind of transition from one domain to another. Yet the transition is possible among the three possible conditions of life in cosmos – animality, humanity and divinity. Human beings may perform the transition to animality as well as the transition to divinity. But no matter the course of the transition, although in different conditions in cosmos, from humanity one will always achieve animality. As conceptualized by Lévi-Strauss, from culture always occurs the trasition to nature. However, in one direction ex-humans will control nature beings, in another one, they will be controlled by nature. This isn’t just about a peculiarity of indigenous groups, it may also be found in societies so-called “modern”, however under others shapes.

Chitosan (Ch) polysaccharide was mixed with phospholipids (P) to generate electrospun hybrid nanofibers intended to be used as platforms for transdermal drug delivery. Ch/P nanofibers exibithed average diameters ranging from 248 +/- 94 nm to 600 +/- 201 nm, depending on the amount of phospholipids...... used. Fourier Transformed Infra-Red (FTIR) spectroscopy and Dynamic Light Scattering (DLS) data suggested the occurrence of electrostatic interactions between amine groups of chitosan with the phospholipid counterparts. The nanofibers were shown to be stable for at least 7 days in Phosphate Buffer...... culture plate (control). The release of curcumin, diclofenac and vitamin B12, as model drugs, from Ch/P hybrid nanofibers was investigated, demonstrating their potential utilization as a transdermal drug delivery system....
