2014-01-01

In this paper, behavior of foundation plates with transverse shear deformation under time variable loading is presented using modified Vlasov foundation model. Finite element formulation of thick plates on elastic foundation is derived by using an 8-noded finite element based on Mindlin plate theory. Selective reduced integration technique is used to avoid shear locking problem which arises when smaller plate thickness is considered for the evaluation of the stiffness matrices. After comparis...

In the mid-1970s, Women Against Violence Against Women (WAVAW), the first national feminist organization to protest mediated sexual violence against women, pressured the music industry to cease using images of violence against women in its advertising. This article presents a case study of WAVAW's national boycott of Warner Communications, Inc. and documents the activists' successful consumer campaign. The study reveals that media violence was central to feminist organizing efforts, and that WAVAW and related organizations helped establish a climate of concern about violence that motivated scientific research on the relationship between exposure to media violence and subsequent aggression.

PURPOSE - The purpose of this paper is to examine the personal views and experiences of Foundation Year 2 doctors operating under the European Working Time Directive (EWTD). DESIGN/METHODOLOGY/APPROACH - In total, 36 Foundation Year 2 doctors from a single UK-based Deanery participated in this semistructured interview study. FINDINGS - Findings indicated that Foundation doctors typically welcomed a regulation of working hours, but reported frustration at the manner in which the Directive had been implemented. Participants reported concerns at reducing hours by removing out-of-hours working in order to meet EWTD requirements. Out-of-hours shifts were highly valued owing to their increased opportunities for autonomous clinical decision making. By contrast, day-shifts were regarded as heavily administrative in nature and were perceived as service provision. Foundation doctors discussed the unique nature of the out-of-hours working period which appeared to provide specific learning opportunities as doctors draw on time management and prioritisation skills. ORIGINALITY/VALUE - Given the challenges the EWTD presents, careful rota planning is essential. First, the authors would encourage the restructuring of day-shift work to provide a greater emphasis on hands-on skills experience in a supportive, supervised environment. Second, where possible, Foundation doctors might benefit from the opportunity to engage in some out-of-hours working, such as with multi-professional "Hospital at Night" teams. Third, the authors would encourage junior doctor involvement in rota design and planning which may increase their perceived autonomy and therefore buy-in of working practices.

Why the American public supports twenty-first century learning.

Aware that constituent support is essential to any educational endeavor, the AOL Time Warner Foundation (now the Time Warner Foundation), in conjunction with two respected national research firms, measured Americans' attitudes toward the implementation of twenty-first century skills. The foundation's national research survey was intended to explore public perceptions of the need for changes in the educational system, in school and after school, with respect to the teaching of twenty-first century skills. The author summarizes the findings of the survey, which were released by the foundation in June 2003. One thousand adults were surveyed by telephone, including African Americans, Latinos, teachers, and business executives. In general, the survey found that Americans believe today's students need a "basics-plus" education, meaning communication, technology, and critical thinking skills in addition to the traditional basics of reading, writing, and math. In fact, 92 percent of respondents stated that students today need different skills from those of ten to twenty years ago. Also, after-school programs were found to be an appropriate vehicle to teach these skills. Furthermore, the survey explored how well the public perceives schools to be preparing youth for the workforce and postsecondary education, which twenty-first century skills are seen as being taught effectively, and the level of need for after-school and summer programs. The survey results provide conclusive evidence of national support for basics-plus education. Thus, a clear opportunity exists to build momentum for a new model of education for the twenty-first century.

Suspended-sediment concentrations (SSCs) and turbidity were monitored within the Beaver Kill, Stony Clove Creek, and Warner Creek tributaries to the upper Esopus Creek in New York, the main source of water to the Ashokan Reservoir, from October 1, 2010, through September 30, 2014. The purpose of the monitoring was to determine the effects of suspended-sediment and turbidity reduction projects (STRPs) on SSC and turbidity in two of the three streams; no STRPs were constructed in the Beaver Kill watershed. During the study period, four STRPs were completed in the Stony Clove Creek and Warner Creek watersheds. Daily mean SSCs decreased significantly for a given streamflow after the STRPs were completed. The most substantial decreases in daily mean SSCs were measured at the highest streamflows. Background SSCs, as measured in water samples collected in upstream reference stream reaches, in all three streams in this study were less than 5 milligrams per liter during low and high streamflows. Longitudinal stream sampling identified stream reaches with failing hillslopes in contact with the stream channel as the primary sediment sources in the Beaver Kill and Stony Clove Creek watersheds.

On the Motivation and Foundation of Natural Time Analysis: Useful Remarks

2016-08-01

Since its introduction in 2001, natural time analysis has been applied to diverse fields with remarkable results. Its validity has not been doubted by any publication to date. Here, we indicate that frequently asked questions on the motivation and the foundation of natural time analysis are directly answered if one takes into account the following two key points that we have considered as widely accepted when natural time analysis was proposed: first, the aspects on the energy of a system forwarded by Max Planck in his Treatise on Thermodynamics; second, the theorem on the characteristic functions of probability distributions which Gauss called Ein Schönes Theorem der Wahrscheinlichkeitsrechnung (beautiful theorem of probability calculus). The case of the time series of earthquakes and of the precursory Seismic Electric Signals are discussed as typical examples.

Full Text Available Significant SNPs associated with Warner-Bratzler (WB shear force and sensory traits were confirmed for Hanwoo beef (Korean cattle. A Bonferroni-corrected genome-wide significant association (p<1.3×10−6 was detected with only one single nucleotide polymorphism (SNP on chromosome 5 for WB shear force. A slightly higher number of SNPs was significantly (p<0.001 associated with WB shear force than with other sensory traits. Further, 50, 25, 29, and 34 SNPs were significantly associated with WB shear force, tenderness, juiciness, and flavor likeness, respectively. The SNPs between p = 0.001 and p = 0.0001 thresholds explained 3% to 9% of the phenotypic variance, while the most significant SNPs accounted for 7% to 12% of the phenotypic variance. In conclusion, because WB shear force and sensory evaluation were moderately affected by a few loci and minimally affected by other loci, further studies are required by using a large sample size and high marker density.

2013-02-01

The tenderness and palatability of retail and food service beef steaks from across the United States (12 cities for retail, 5 cities for food service) were evaluated using Warner-Bratzler shear (WBS) and consumer sensory panels. Subprimal postfabrication storage or aging times at retail establishments averaged 20.5 d with a range of 1 to 358 d, whereas postfabrication times at the food service level revealed an average time of 28.1 d with a range of 9 to 67 d. Approximately 64% of retail steaks were labeled with a packer/processor or store brand. For retail, top blade had among the lowest (P 0.05) in WBS values between moist-heat and dry-heat cookery methods for the top round and bottom round steaks or between enhanced (contained salt or phosphate solution) or nonenhanced steaks. Food service top loin and rib eye steaks had the lowest (P food service top loin steaks received among the greatest (P food service rib eye steaks received the greatest ratings (P food service steaks were greater (P Choice, and Low Choice groups. The WBS values and sensory ratings were comparable to the last survey, signifying that no recent or substantive changes in tenderness have occurred.

Full Text Available The plastron theory was tested in adults of Neochetina eichhorniae Warner, 1970, through the analysis of the structure that coats these insects' integument and also through submersion laboratorial experiments. The tegument processes were recognized in three types: agglutinated scales with large perforations, plumose scales of varied sizes and shapes, and hairs. The experiments were carried out on 264 adult individuals which were kept submerged at different time intervals (n = 11 and in two types of treatment, natural non-aerated water and previously boiled water, with four repetitions for each treatment. The tests showed a maximum mortality after 24 hours of immersion in the previously boiled water treatment. The survival of the adults was negative and significantly correlated with the types of treatment employed and within the different time intervals. The values of oxygen dissolved in water (mg/l differed significantly within the types of treatment employed. They were positively correlated with the survival of the adults in the two types of treatment, although more markedly in the treatment with previously boiled water. The mortality of adults after 24 hours of submersion in the treatment with previously boiled water may be associated with the physical-chemical conditions of the non-tested water in this study, such as low surface tension and concentration of solutes. These results suggest plastron functionality in the adults of this species.A teoria plastrão foi testada em adultos de Neochetina eichhorniae Warner, 1970, por meio da análise da estrutura que reveste o tegumento destes insetos e em experimentos laboratoriais de submersão.

Time as a Quantum Observable, Canonically Conjugated to Energy, and Foundations of Self-Consistent Time Analysis of Quantum Processes

Directory of Open Access Journals (Sweden)

V. S. Olkhovsky

2009-01-01

Full Text Available Recent developments are reviewed and some new results are presented in the study of time in quantum mechanics and quantum electrodynamics as an observable, canonically conjugate to energy. This paper deals with the maximal Hermitian (but nonself-adjoint operator for time which appears in nonrelativistic quantum mechanics and in quantum electrodynamics for systems with continuous energy spectra and also, briefly, with the four-momentum and four-position operators, for relativistic spin-zero particles. Two measures of averaging over time and connection between them are analyzed. The results of the study of time as a quantum observable in the cases of the discrete energy spectra are also presented, and in this case the quasi-self-adjoint time operator appears. Then, the general foundations of time analysis of quantum processes (collisions and decays are developed on the base of time operator with the proper measures of averaging over time. Finally, some applications of time analysis of quantum processes (concretely, tunneling phenomena and nuclear processes are reviewed.

Estimation of Sensory Pork Loin Tenderness Using Warner-Bratzler Shear Force and Texture Profile Analysis Measurements.

2016-07-01

This study investigated the degree to which instrumental measurements explain the variation in pork loin tenderness as assessed by the sensory evaluation of trained panelists. Warner-Bratzler shear force (WBS) had a significant relationship with the sensory tenderness variables, such as softness, initial tenderness, chewiness, and rate of breakdown. In a regression analysis, WBS could account variations in these sensory variables, though only to a limited proportion of variation. On the other hand, three parameters from texture profile analysis (TPA)-hardness, gumminess, and chewiness-were significantly correlated with all sensory evaluation variables. In particular, from the result of stepwise regression analysis, TPA hardness alone explained over 15% of variation in all sensory evaluation variables, with the exception of perceptible residue. Based on these results, TPA analysis was found to be better than WBS measurement, with the TPA parameter hardness likely to prove particularly useful, in terms of predicting pork loin tenderness as rated by trained panelists. However, sensory evaluation should be conducted to investigate practical pork tenderness perceived by consumer, because both instrumental measurements could explain only a small portion (less than 20%) of the variability in sensory evaluation.

Patient Engagement: Time to Shake the Foundations.

Something big is happening in healthcare. It's not the new Apple Watch, 3D printing or the advent of personalized medicine. It's people power. And, it is starting to shake up the very foundation on which healthcare systems around the world have been built. Healthcare professionals and hospitals are iconic features on a healthcare landscape that has been purpose-built with castles, moats and defence artillery. Turf protection, often under the guise of "patient protection," has become so ingrained in the way things are that few recognize what it has become. Fooks et al. step gently into this somewhat dangerous territory for "insiders" of the system to tread; yet in my view, they do not go far enough.

Critique of the foundations of time-dependent density-functional theory

International Nuclear Information System (INIS)

Schirmer, J.; Dreuw, A.

2007-01-01

The general expectation that, in principle, the time-dependent density-functional theory (TDDFT) is an exact formulation of the time evolution of an interacting N-electron system is critically reexamined. It is demonstrated that the previous TDDFT foundation, resting on four theorems by Runge and Gross (RG) [Phys. Rev. Lett. 52, 997 (1984)], is invalid because undefined phase factors corrupt the RG action integral functionals. Our finding confirms much of a previous analysis by van Leeuwen [Int. J. Mod. Phys. B 15, 1969 (2001)]. To analyze the RG theorems and other aspects of TDDFT, an utmost simplification of the Kohn-Sham (KS) concept has been introduced, in which the ground-state density is obtained from a single KS equation for one spatial (spinless) orbital. The time-dependent (TD) form of this radical Kohn-Sham (rKS) scheme, which has the same validity status as the ordinary KS version, has proved to be a valuable tool for analysis. The rKS concept is used to clarify also the alternative nonvariational formulation of TD KS theory. We argue that it is just a formal theory, allowing one to reproduce but not predict the time development of the exact density of the interacting N-electron system. Besides the issue of the formal exactness of TDDFT, it is shown that both the static and time-dependent KS linear response equations neglect the particle-particle (p-p) and hole-hole (h-h) matrix elements of the perturbing operator. For a local (multiplicative) operator this does not lead to a loss of information due to a remarkable general property of local operators. Accordingly, no logical inconsistency arises with respect to DFT, because DFT requires any external potential to be local. For a general nonlocal operator the error resulting from the neglected matrix elements is of second order in the electronic repulsion

Madness and the Middle Passage: Warner-Vierya's Juletane as a Paradigm for Writing Caribbean Women's Identities

Directory of Open Access Journals (Sweden)

Ann Elizabeth Willey

1997-06-01

Full Text Available This article links Glissant's theory of an inherent Caribbean madness due to the originary rupture and alienation from Africa with Foucault's theory of the ritual significance and essential liminality of the madman as exemplified in the medieval figure of the "Ship of Fools." In calling the madman the "passenger par excellence," Foucault implies a connection between sanity and linear narratives, such as that of a voyage. Myriam Warner-Vierya's novel, Juletane , suggests that European paradigms of narrative and voyage are inadequate to provide a sense of self for Caribbean women. The novel takes the form of a diary that chronicles the steadily disintegrating marriage and sanity of Juletane, a Caribbean woman orphaned at ten, raised in Paris, who meets and marries an African student in an effort to find a new identity in her husband and a return to Africa. The novel suggests that the linear narrative of a return to the source in Africa denies the rupture with Africa and the immediate circumstances of Caribbean subject-hood. In her efforts, Juletane ignores the alternative narrative possibilities that the novel presents in the circular and shared narratives of women that do not depend on a sense of closure or arrival, but like the voyage of the madman, remain open to the infinite crossroads of the sea and narration.

The effects of climate-driven stressors on organismal performance and ecosystem functioning have been investigated across many systems; however, manipulative experiments generally apply stressors as constant and simultaneous treatments, rather than accurately reflecting temporal patterns in the natural environment. Here, we assessed the effects of temporal patterns of high aerial temperature and low salinity on survival of Olympia oysters (Ostrea lurida), a foundation species of conservation and restoration concern. As single stressors, low salinity (5 and 10 psu) and the highest air temperature (40°C) resulted in oyster mortality of 55.8, 11.3, and 23.5%, respectively. When applied on the same day, low salinity and high air temperature had synergistic negative effects that increased oyster mortality. This was true even for stressor levels that were relatively mild when applied alone (10 psu and 35°C). However, recovery times of two or four weeks between stressors eliminated the synergistic effects. Given that most natural systems threatened by climate change are subject to multiple stressors that vary in the timing of their occurrence, our results suggest that it is important to examine temporal variation of stressors in order to more accurately understand the possible biological responses to global change. © 2017 by the Ecological Society of America.

The Application of Foundation Pit Monitoring Technology to the Excavation

Full Text Available The foundation pit monitoring plays an important role in the foundation pit supporting projects especially in those deep foundation pit projects. Through the whole monitoring of the foundation pit construction from the excavation to the backfill, we can learn about the forcing and deforming process of the foundation pit supporting system, and grasp the impact of external condition changes on the foundation pit. This paper takes a project in Jinan as an example to establish a specific monitoring program, and then conducts the analysis and evaluation of the monitoring data; the real-time grasp of the foundation pit deformation and internal force changes can help to further ensure the security status of the foundation pit, thus better guiding the construction.

Wireless Concrete Strength Monitoring of Wind Turbine Foundations.

Perry, Marcus; Fusiek, Grzegorz; Niewczas, Pawel; Rubert, Tim; McAlorum, Jack

2017-12-16

Wind turbine foundations are typically cast in place, leaving the concrete to mature under environmental conditions that vary in time and space. As a result, there is uncertainty around the concrete's initial performance, and this can encourage both costly over-design and inaccurate prognoses of structural health. Here, we demonstrate the field application of a dense, wireless thermocouple network to monitor the strength development of an onshore, reinforced-concrete wind turbine foundation. Up-to-date methods in fly ash concrete strength and maturity modelling are used to estimate the distribution and evolution of foundation strength over 29 days of curing. Strength estimates are verified by core samples, extracted from the foundation base. In addition, an artificial neural network, trained using temperature data, is exploited to demonstrate that distributed concrete strengths can be estimated for foundations using only sparse thermocouple data. Our techniques provide a practical alternative to computational models, and could assist site operators in making more informed decisions about foundation design, construction, operation and maintenance.

Transient Monotonic and Cyclic Load Effects on Mono Bucket Foundations

DEFF Research Database (Denmark)

Nielsen, Søren Dam

Today, 80 % of all European offshore wind turbines are installed on monopiles. A cost-effective alternative to the monopile is the mono bucket foundation. For an offshore wind turbine foundation in open seas, the dominant load is often coming from waves. During storms, large waves are formed...... the foundation is sucked to the seabed, creating extra capacity during the impact. Over the life-time of an offshore wind turbine foundation will be hit by millions of waves. Each wave might lead to a permanent rotation of the foundation. Therefore, it is important to be able to estimate the total deformation...

Furthermore, environment is often not the only objective and sometimes not even processed. Our analysis shows that there are different types of foundations with regard to environmental scopes and activities. Although “attractive topics” such as biodiversity and landscape conservation seem to be more important to foundations, less visible topics such as pollution prevention remain merely a “blind spot.” Together, these findings suggest that there is only a limited potential of private foundations compared with public foundations. Nevertheless, there might be an impact on environmental awareness and local sustainability.

The degradation of onshore, reinforced-concrete wind turbine foundations is usually assessed via above-ground inspections, or through lengthy excavation campaigns that suspend wind power generation. Foundation cracks can and do occur below ground level, and while sustained measurements of crack behaviour could be used to quantify the risk of water ingress and reinforcement corrosion, these cracks have not yet been monitored during turbine operation. Here, we outline the design, fabrication and field installation of subterranean fibre-optic sensors for monitoring the opening and lateral displacements of foundation cracks during wind turbine operation. We detail methods for in situ sensor characterisation, verify sensor responses against theoretical tower strains derived from wind speed data, and then show that measured crack displacements correlate with monitored tower strains. Our results show that foundation crack opening displacements respond linearly to tower strain and do not change by more than ±5 μ m. Lateral crack displacements were found to be negligible. We anticipate that the work outlined here will provide a starting point for real-time, long-term and dynamic analyses of crack displacements in future. Our findings could furthermore inform the development of cost-effective monitoring systems for ageing wind turbine foundations.

Forced in-plane vibration of a thick ring on a unilateral elastic foundation

Wang, Chunjian; Ayalew, Beshah; Rhyne, Timothy; Cron, Steve; Dailliez, Benoit

2016-10-01

Most existing studies of a deformable ring on elastic foundation rely on the assumption of a linear foundation. These assumptions are insufficient in cases where the foundation may have a unilateral stiffness that vanishes in compression or tension such as in non-pneumatic tires and bushing bearings. This paper analyzes the in-plane dynamics of such a thick ring on a unilateral elastic foundation, specifically, on a two-parameter unilateral elastic foundation, where the stiffness of the foundation is treated as linear in the circumferential direction but unilateral (i.e. collapsible or tensionless) in the radial direction. The thick ring is modeled as an orthotropic and extensible circular Timoshenko beam. An arbitrarily distributed time-varying in-plane force is considered as the excitation. The Equations of Motion are explicitly derived and a solution method is proposed that uses an implicit Newmark scheme for the time domain solution and an iterative compensation approach to determine the unilateral zone of the foundation at each time step. The dynamic axle force transmission is also analyzed. Illustrative forced vibration responses obtained from the proposed model and solution method are compared with those obtained from a finite element model.

Buckling of Bucket Foundations During Installation

DEFF Research Database (Denmark)

Madsen, Søren

There is a great politically will to expand the green energy market in these times. A proven green technology is wind turbines. Wind turbines have been installed in great numbers on land over the last decades. However, the current development in wind turbine design leads to larger turbine sizes...... in order to reduce the cost of energy. This limits the on land application due to transportation limitations and unwillingness from prospect neighbours. Thus, offshore wind energy started developing over the last couple of years. Although installing the wind turbines offshore resolves the before men tioned...... issues, it brings up the cost of energy mainly due to increased installation and maintenance costs. A very large part—up to 30–50% using current technology—of the installation cost origins from the expenses related to the installation of foundations.

Shells on elastic foundations

International Nuclear Information System (INIS)

Das, Y.C.; Kedia, K.K.

1977-01-01

No realistic analytical work in the area of Shells on Elastic Foundations has been reported in the literature. Various foundation models have been proposed by several authors. These models involve one or more than one parameters to characterise the foundation medium. Some of these models cannot be used to derive the basic equations governing the behaviour of shells on elastic foundations. In the present work, starting from an elastic continuum hypothesis, a mathematical model for foundation has been derived in curvilinear orthogonal coordinates by the help of principle of virtual displacements, treating one of the virtual displacements as known to satisfy certain given conditions at its edge surfaces. In this model, several foundation parameters can be considered and it can also be used for layered medium of both finite and infinite thickness. (Auth.)

Pile foundation of nuclear power plant structures

1978-01-01

The subject of pile foundation used for nuclear power plant structures, considering the experience gained by the designers of the Angra Nuclear Power Plant, Units 2 and 3 in Brazil is dealt with. The general concept of the pile foundations, including types and execution of the piles, is described briefly. Then the two basic models, i.e. the static model and the dynamic one, used in the design are shown, and the pertinent design assumptions as related to the Angra project are mentioned. The criteria which established the loading capacity of the piles are discussed and the geological conditions of the Angra site are also explained briefly, justifying the reasons why pile foundations are necessary in this project. After that, the design procedures and particularly the tools - i.e. the computer programs - are described. It is noted that the relatively simple but always time consuming job of loading determination calculations can be computerized too, as it was done on this project through the computer program SEASA. The interesting aspects of soil/structure interaction, applicable to static models, are covered in detail, showing the theoretical base wich was used in the program PILMAT. Then the advantage resulting from computerizing of the job of pile reinforcement design are mentioned, describing briefly the jobs done by the two special programs PILDES and PILTAB. The point is stressed that the effort computerizing the structural design of this project was not so much due to the required accuracy of the calculations, but mainly due to the need to save on the design time, as to allow to perform the design task within the relatively tight time schedule. A conclusion can be drawn that design of pile foundations for nuclear power plant structures is a more complex task than the design of bearing type of foundation for the same structures, but that the task can be always made easier when the design process can be computerized.

A foundation for foundation phase teacher education: Making wise educational judgements

2014-12-01

Full Text Available We start our paper with a critical exploration of the current ‘back to basics’ approach in South African foundation phase teacher education with its emphasis on strengthening the teaching of subject knowledge. We claim that such a proposal first demands an answer to the question ‘what is foundational in foundation phase teaching?’ We propose an answer in three stages. First we argue that teacher education should be concerned not only with schooling or qualification (knowledge, skills and dispositions and socialisation, but, drawing on Gert Biesta’s work, also with subjectification (educating the person towards the ability to make wise educational judgements. Secondly, these three aims of education lead to five core principles, and we finish by showing how these principles inform our storied, thinking and multimodal/semiotic curriculum. Our answer to our leading question is that pedagogical ‘know-how’ and views of ‘child’ and ‘childhood’ constitute the subject knowledge that is foundational in the foundation phase curriculum.

Prototype bucket foundation for wind turbines - natural frequency estimation

Energy Technology Data Exchange (ETDEWEB)

Ibsen, Lars Bo; Liingaard, M.

2006-12-15

The first full scale prototype bucket foundation for wind turbines has been installed in October 2002 at Aalborg University offshore test facility in Frederikshavn, Denmark. The suction caisson and the wind turbine have been equipped with an online monitoring system, consisting of 15 accelerometers and a real-time data-acquisition system. The report concerns the in service performance of the wind turbine, with focus on estimation of the natural frequencies of the structure/foundation. The natural frequencies are initially estimated by means of experimental Output-only Modal analysis. The experimental estimates are then compared with numerical simulations of the suction caisson foundation and the wind turbine. The numerical model consists of a finite element section for the wind turbine tower and nacelle. The soil-structure interaction of the soil-foundation section is modelled by lumped-parameter models capable of simulating dynamic frequency dependent behaviour of the structure-foundation system.

1976-01-01

A new foundation of quantum theory is given on the basis of the formulated 'Principle of Fundamental Covariance', combining the 'Principle of General Relativity' (coordinate-covariance in space-time) and the 'Principle of Operator-Covariance' (in Hilbert space). The fundamental quantum laws proposed are: (1) time-dependent simultaneous laws of motion for the operators, general states and eigenstates, (2) commutation relations, (3) time-dependent eigenvalue equations. All these laws fulfill the Principle of Fundamental Covariance (in non-relativistic quantum mechanics with restricted coordinate transformations). (author)

Consolidation Theory for a Stone Column Composite Foundation under Multistage Loading

Directory of Open Access Journals (Sweden)

Shenggen Huang

2016-01-01

Full Text Available The consolidation theories considering instant load cannot fully reveal the consolidation mechanism of a stone column composite foundation used in the expressway embankments due to the time effect of loading; that is, the expressway embankments are often constructed in several stages for a long time. Meanwhile, owing to the special property that the pile-soil stress ratio is larger than 1, the consolidation theory for sand drain well foundation cannot be used directly in the consolidation analysis of stone column composite foundation. Based on the principle that the vertical load applied on the composite foundation is shared by the stone column and the surrounding soil, the governing solutions for the stone column composite foundation under a multistage load are established. By virtue of the separation of variables, the corresponding solutions of degree of consolidation for loading stage and maintaining load stage are derived separately. According to the Carrillo theorem, the solution for the average total degree of consolidation of entire composite foundation is also obtained. Finally, the reasonableness of the present solution has been verified by comparing the consolidation curve calculated by the present solution with that measured by site test.

Static Behaviour of Bucket Foundations

DEFF Research Database (Denmark)

Larsen, Kim André

One new foundation concept in relation to offshore wind turbines is bucket foundations. The concept is known from the oil and gas industry, though the load conditions here are significantly different. The bucket foundation can be used as monopod or e.g. tripod foundations for offshore wind turbines....... The monopod concept is investigated in this thesis, regarding the static behaviour from loads relevant to offshore wind turbines. The main issue in this concept is the rotational stiffness of the foundation and the combined capacity dominated by moments. The vertical bearing capacity of bucket foundations...... theory is proposed. The proposed expression applies to plane strain as well as axis-symmetric stress conditions for foundations with smooth or rough bases. A thorough experimental investigation of the static behaviour of bucket foundations subjected to combined loading is carried out. Laboratory tests...

Probability and sensitivity analysis of machine foundation and soil interaction

Directory of Open Access Journals (Sweden)

Králik J., jr.

2009-06-01

Full Text Available This paper deals with the possibility of the sensitivity and probabilistic analysis of the reliability of the machine foundation depending on variability of the soil stiffness, structure geometry and compressor operation. The requirements to design of the foundation under rotating machines increased due to development of calculation method and computer tools. During the structural design process, an engineer has to consider problems of the soil-foundation and foundation-machine interaction from the safety, reliability and durability of structure point of view. The advantages and disadvantages of the deterministic and probabilistic analysis of the machine foundation resistance are discussed. The sensitivity of the machine foundation to the uncertainties of the soil properties due to longtime rotating movement of machine is not negligible for design engineers. On the example of compressor foundation and turbine fy. SIEMENS AG the affectivity of the probabilistic design methodology was presented. The Latin Hypercube Sampling (LHS simulation method for the analysis of the compressor foundation reliability was used on program ANSYS. The 200 simulations for five load cases were calculated in the real time on PC. The probabilistic analysis gives us more complex information about the soil-foundation-machine interaction as the deterministic analysis.

Theoretical investigation of interaction between a rectangular plate and fractional viscoelastic foundation

Directory of Open Access Journals (Sweden)

Chengcheng Zhang

2014-08-01

Full Text Available The interaction between plates and foundations is a typical problem encountered in geotechnical engineering. The long-term plate performance is highly dependent on the rheological characteristics of ground soil. Compared with conventional linear rheology, the fractional calculus-based theory is a more powerful mathematical tool that can address this issue. This paper proposes a fractional Merchant model (FMM to investigate the time-dependent behavior of a simply supported rectangular plate on viscoelastic foundation. The correspondence principle involving Laplace transforms was employed to derive the closed-form solutions of plate response under uniformly distributed load. The plate deflection, bending moment, and foundation reaction calculated using the FMM were compared with the results obtained from the analogous elastic model (EM and the standard Merchant model (SMM. It is shown that the upper and lower bound solutions of the FMM can be determined using the EM. In addition, a parametric study was performed to examine the influences of the model parameters on the time-dependent behavior of the plate–foundation interaction problem. The results indicate that a small fractional differential order corresponds to a plate resting on a sandy soil foundation, while the fractional differential order value should be increased for a clayey soil foundation. The long-term performance of a foundation plate can be accurately simulated by varying the values of the fractional differential order and the viscosity coefficient. The observations from this study reveal that the proposed fractional model has the capability to capture the variation of plate deflection over many decades of time.

Some results of numerical calculations are presented to demonstrate the potential of the proposed approach to the mathematical simulation of spatiotemporal physicochemical reaction dynamics.

The road to Maxwell's demon conceptual foundations of statistical mechanics

CERN Document Server

Hemmo, Meir

2012-01-01

Time asymmetric phenomena are successfully predicted by statistical mechanics. Yet the foundations of this theory are surprisingly shaky. Its explanation for the ease of mixing milk with coffee is incomplete, and even implies that un-mixing them should be just as easy. In this book the authors develop a new conceptual foundation for statistical mechanics that addresses this difficulty. Explaining the notions of macrostates, probability, measurement, memory, and the arrow of time in statistical mechanics, they reach the startling conclusion that Maxwell's Demon, the famous perpetuum mobile, is consistent with the fundamental physical laws. Mathematical treatments are avoided where possible, and instead the authors use novel diagrams to illustrate the text. This is a fascinating book for graduate students and researchers interested in the foundations and philosophy of physics.

Can Innate, modular "foundations" explain morality? Challenges for Haidt's Moral Foundations Theory.

Science.gov (United States)

Suhler, Christopher L; Churchland, Patricia

2011-09-01

Jonathan Haidt's Moral Foundations Theory is an influential scientific account of morality incorporating psychological, developmental, and evolutionary perspectives. The theory proposes that morality is built upon five innate "foundations," each of which is believed to have been selected for during human evolution and, subsequently, tuned-up by learning during development. We argue here that although some general elements of Haidt's theory are plausible, many other important aspects of his account are seriously flawed. First, innateness and modularity figure centrally in Haidt's account, but terminological and conceptual problems foster confusion and ambiguities. Second, both the theory's proposed number of moral foundations and its taxonomy of the moral domain appear contrived, ignoring equally good candidate foundations and the possibility of substantial intergroup differences in the foundations' contents. Third, the mechanisms (viz., modules) and categorical distinctions (viz., between foundations) proposed by the theory are not consilient with discoveries in contemporary neuroscience concerning the organization, functioning, and development of the brain. In light of these difficulties, we suggest that Haidt's theory is inadequate as a scientific account of morality. Nevertheless, the theory's weaknesses are instructive, and hence, criticism may be useful to psychologists, neuroscientists, and philosophers attempting to advance theories of morality, as well as to researchers wishing to invoke concepts such as innateness and modularity more generally.

Effect of soil stabilized by cement on dynamic response of machine foundations

Directory of Open Access Journals (Sweden)

Al-Wakel Saad

2018-01-01

Full Text Available Machine foundations require significant attention from designers. The main goal of the design of machine foundation is to limit the amplitude displacement and not disturb the people who work near the machine. In some cases, if the design of machine foundations does not satisfy the acceptable value of the dynamic response (such as maximum amplitude of displacement, the stabilization of soil under the machine foundation may be used to decrease the amplitude of displacement. This paper outlines effect of stabilized soil under the foundation by cement on the displacement response of machine foundations. Three-dimensional analyses by using finite element method are carried out to investigate the effect of depth of stabilized layer with different percentage of cement content on the dynamic response of the machine foundation. In addition, the effect of area stabilized by cement material on the dynamic response of machine foundation is investigated. The results shown that, the dynamic response of machine foundations generally decreases with increasing the depth of soil layer stabilized with cement. A significant decrease in the displacement of machine foundations is occurred for the stabilized soil layer with a depth of two times of the width of foundation, and the optimum percentage of cement for stabilizing is 6%.

The role of foundations: Rockefeller Foundation.

Science.gov (United States)

Rockefeller, David

The consequences of climate change and the impacts of human activity on the environment have made it clearer than ever before that we must evolve our current model of public health to better account for the inextricable link between human health and the natural systems on which it depends-creating a "public health 2.0" that builds on the innovations of the twentieth century to account for a world where humans have bypassed planetary boundaries to achieve well-being. First coined at the Rockefeller Foundation's Centennial gathering in Beijing in 2013, "Planetary Health" will factor in future health and environmental harms over present-day gains, particularly those that disproportionately affect the poor and those in developing nations. To build this new field, foundations must address the challenge of information, increasing support for research to bridge knowledge gaps on the links between economic development, natural systems, and human health.

The Dynamics of Associations and Foundations in Romania. Econometric Analysis

Directory of Open Access Journals (Sweden)

2017-09-01

Full Text Available This article highlights the evolutionary trend of the associations and foundations in Romania in 1997 – 2015 period of time. We know that the NPO's activities come to cover the people's needs which cannot be supported by the state or by the private sector. More precisely, the major roles of the NPO sector are: supporting disadvantaged groups and the social causes, sustaining the role of "watchdog", and promoting the advocacy and public policy expertise. For this reason, we propose an econometric model that will be applied to establish the link between the number of the association and foundations, poverty rate, unemployment rate and the average monthly expenditure per household. We consider that the last three factors are relevant to the country’s social economy and, at the same time, they represent the main objectives of the EUROPE 2020 Strategy - a strategy for smart, sustainable and inclusive growth. The study is based on numerical data collected over a period of 12 years from 2003 to 2014. For the econometric model, we use IBM SPSS 22 software, in analyzing the collected data. After processing the data we will find a positive and significant relation between the number of associations and foundations (AF, the average monthly expenditure per household and the poverty rate. At the same time, we will find an insignificant relation between the number of associations and foundations and the unemployment rate.

Quantum non-locality has been an extremely fruitful subject of research, leading the scientific revolution towards quantum information science, in particular, to device-independent quantum information processing. We argue that the time is ripe to work on another basic problem in the foundations of quantum physics, the quantum measurement problem, which should produce good physics in theoretical, mathematical, experimental and applied physics. We briefly review how quantum non-locality contributed to physics (including some outstanding open problems) and suggest ways in which questions around macroscopic quantumness could equally contribute to all aspects of physics.This article is part of a discussion meeting issue 'Foundations of quantum mechanics and their impact on contemporary society'. © 2018 The Author(s).

A more accurate assessment of slab-on-grade foundation insulation energy savings than traditionally possible is now feasible. This has been enabled by advances in whole building energy simulation with 3-dimensional foundation modelling integration at each time step together with an experimental measurement of the site energy savings of SOG foundation insulation. Ten SOG insulation strategies were evaluated on a test building to identify an optimum retrofit insulation strategy in a zone 6 climate (Minneapolis, MN). The optimum insulation strategy in terms of energy savings and cost effectiveness consisted of two components: (a) R-20 XPS insulation above grade, and, (b) R-20 insulation at grade (comprising an outer layer of R-10 insulation and an interior layer of R-12 poured polyurethane insulation) tapering to R-10 XPS insulation at half the below-grade wall height (the lower half of the stem wall was uninsulated).

Sam Austin

2017-09-01

Full Text Available Soil-foundation-structure interaction can affect the seismic response of wind turbines. This paper studies the effects of soil-foundation-structure interaction on the seismic response of 65 kW, 1 MW, and 2 MW horizontal-axis wind turbines with truncated cone steel towers. Four types of foundations with frequency-based design were analyzed, including spread foundation, mono pile, pile group with cap, and anchored spread foundation. Soil is modeled both implicitly (subgrade reaction modulus and explicitly. The finite element model developed using the ANSYS program was first validated using experimental data. Numerical models are then analyzed in both frequency and time domains using the Block Lanczos and generalized HHT-α formulations. Recommendations were given to simplify the soil-foundation-structure interaction analysis of wind turbines subjected to seismic loading.

?A more accurate assessment of SOG foundation insulation energy savings than traditionally possible is now feasible. This has been enabled by advances in whole building energy simulation with 3-dimensional foundation modelling integration at each time step together with an experimental measurement of the site energy savings of SOG foundation insulation. Ten SOG insulation strategies were evaluated on a test building to identify an optimum retrofit insulation strategy in a zone 6 climate (Minneapolis, MN). The optimum insulation strategy in terms of energy savings and cost effectiveness consisted of two components: (a) R-20 XPS insulation above grade, and, (b) R-20 insulation at grade (comprising an outer layer of R-10 insulation and an interior layer of R-12 poured polyurethane insulation) tapering to R-10 XPS insulation at half the below-grade wall height (the lower half of the stem wall was uninsulated). The optimum insulation strategy was applied to single and multi-family residential buildings in climate zone 4 - 7. The highest site energy savings of 5% was realized for a single family home in Duluth, MN, and the lowest savings of 1.4 % for a 4-unit townhouse in Richmond, VA. SOG foundation insulation retrofit simple paybacks ranged from 18 to 47 years. There are other benefits of SOG foundation insulation resulting from the increase in the slab surface temperatures. These include increased occupant thermal comfort, and a decrease in slab surface condensation particularly around the slab perimeter.

NUMERICAL MODELLING OF CHICKEN-FOOT FOUNDATION

Directory of Open Access Journals (Sweden)

Vipman Tandjiria

1999-01-01

Full Text Available This paper presents an analysis of the chicken-foot foundation using the finite element method. The foundation is considered as a reinforced concrete slab resting on a number of reinforced concrete pipes filled with and surrounded by in-situ soil. The soil and the pipes were modelled by isoparametric solid elements while the slab was modelled by isoparametric thick-plate elements. The study was intended to illustrate the basic mechanism of the chicken-foot foundation. Three cases have been considered for the parametric studies. The parameters investigated are thickness of slab, length of pipes and spacing between pipes. It is shown that such a foundation improves the behaviour of the raft foundation. It is also found that all the parameters used in the parametric studies influence the behaviour of the chicken-foot foundation.

Full Text Available The higher education system which entered a new period with the 1980s has in the last five years entered a phase of numerical enlargement and structural transformation. Having only 19 public universities in the early 1980s, the higher education system today have turned into a broad system with 85 public and 30 foundation universities. The research aims to discuss the role of foundation universities in the higher education policies implemented between the years 1980-2007. Among the five development plans prepared between 1980 and 2008, it was suggested for the first time with the sixth five-year development plan that foundations should be supported to establish private universities and policies was formulated accordingly. Mesut Yılmaz was the prime minister and Süleyman Demirel was the president who opened the highest number of foundation universities between 1980 and 2008. While the number of students between 1986-1987 was 426 in foundation universities, this number in foundation universities reached 109.903 in the 2006-2007 aca-demic year. The annual growth rate of the number of students in foundation universities within the twenty-year period is 32%. In the 2006-2007 academic year, the number of academic staff in foundation universities is 7766, of academic fellows is 2502, and of students is 109,903. The number of students per academic staff in foundation universities in the 2006-2007 academic year is 21, whereas the number of students per academic fellow is 44.

1992-01-01

In the last 3 decades the field of mechanics has seen spectacular progress due to the demand for applications in problems of cosmology, thermonuclear fusion, metallurgy, etc. This book provides a broad and thorough overview on the foundations of mechanics. It discusses theoretical mechanics and continuum mechanics, as well as phenomenological thermodynamics, quantum mechanics and relativistic mechanics. Each chapter presents the basic physical facts of interest without going into details and derivations and without using advanced mathematical formalism. The first part constitutes a classical exposition of Lagrange's and Hamiltonian's analytical mechanics on which most of the continuum theory is based. The section on continuum mechanics focuses mainly on the axiomatic foundations, with many pointers for further research in this area. Special attention is given to modern continuum thermodynamics, both for the foundations and applications. A section on quantum mechanics is also included, since the phenomenological description of various quantum phenomena is becoming of increasing importance. refs.; figs.; tabs

Significance of foundation-soil separation in dynamic soil-structure interaction

Science.gov (United States)

Spyrakos, Constantine C.; Patel, P. N.

1987-01-01

THe dynamic response of flexible surface strip-foundations allowed to uplift is numerically obtained for externally applied forces of a transient time variation. The soil medium is represented by an isotropic, homogeneous and linear half-space. The soil is treated by a time domain boundary element method, while the flexible foundation is treated by the finite element method. It was concluded that intermediate relative stiffness leads to moderate deformations when uplift is permitted. Very flexible footings produce higher deformations in unilateral contact compared to bilateral contact, and thus should be considered in their design. Unilateral contact does not significantly increase deformations for stiff footings subjected to concentrated central loading. However, relatively large deformation differences occur when the loading is eccentric, necessitating consideration of uplift in their design.

The foundation of self-esteem.

Science.gov (United States)

Bailey, Joseph A

2003-05-01

Self-esteem is a simplistic term for varied and complex mental states pertaining to how one views oneself. It takes but little research in the voluminous literature to see the vagueness and inconsistencies in its various definitions. Even more problematic is the uncertainty concerning its foundational components. The importance of having a solid definition and specific ideas about the foundational components of self-esteem is that both pave the way to recognizing its causes; to predicting effects from those causes; and to organizing the trouble-shooting process for locating those philosophical flaws or psychological scars which lead to low self-esteem. The purpose of this paper is to offer a common ground for thinking about self-esteem at its most basic level. In order to distinguish the "basic level" from the rest of the components of self-esteem, let us liken it to a skyscraper building. Here, the focus is on the building's "underground foundation" and the base upon which that foundation rests. The base is a definition that allows for the assessment of the foundation. The underground foundation itself consists of the mental building blocks called self-meaning, self-identity, self-image, and self-concepts. To help illustrate their interactions, a few of the "masks" and "faces" of self-esteem will be mentioned. What is not being addressed is the "above ground structure"--those theories and manifestations dealt with by most mental health specialists.

The APA Ethical Principles as a foundational competency: application to rehabilitation psychology.

Science.gov (United States)

Hanson, Stephanie L; Kerkhoff, Thomas R

2011-08-01

Competence is a core component of ethical conduct as reflected in its addition as an ethical standard in the 2002 APA Ethics Code. Successfully operationalizing and assessing competence provides psychologists a means to improve education and training, advance the field of practice, and create a framework for accountability to the public. Much of the recent competency discussion has been in response to a proposed Cube Model, with its three axes being foundational competencies (practice building blocks, such as scientific knowledge, ethical standards), functional competencies (attributes of providing services, such as assessment, intervention), and developmental progression (acquiring increasing competence over the course of one's education and career). Ethics is included on the foundational competency axis and has been operationalized to the extent that subcomponents and benchmarks have been promulgated. The competency model as proposed faces multiple challenges, including gaining consensus regarding its components, addressing reliable and valid assessment over time, and creating a culture of acceptance. We propose the Ethical Principles as an alternative framework for conceptualizing ethics as a foundational competency given the Ethics Code is already time tested and includes a serial review process for broad discipline input and adaptability. We apply the Ethical Principles as foundational components to rehabilitation psychology training at internship, postdoctoral, and specialty levels to illustrate the model. Rehabilitation psychology should engage in the competency movement at the predoctoral and postdoctoral level. The application of the Ethical Principles as a foundational competency to rehabilitation psychology represents a first step in this dialog.

Seismic isolation of two dimensional periodic foundations

International Nuclear Information System (INIS)

Yan, Y.; Mo, Y. L.; Laskar, A.; Cheng, Z.; Shi, Z.; Menq, F.; Tang, Y.

2014-01-01

Phononic crystal is now used to control acoustic waves. When the crystal goes to a larger scale, it is called periodic structure. The band gaps of the periodic structure can be reduced to range from 0.5 Hz to 50 Hz. Therefore, the periodic structure has potential applications in seismic wave reflection. In civil engineering, the periodic structure can be served as the foundation of upper structure. This type of foundation consisting of periodic structure is called periodic foundation. When the frequency of seismic waves falls into the band gaps of the periodic foundation, the seismic wave can be blocked. Field experiments of a scaled two dimensional (2D) periodic foundation with an upper structure were conducted to verify the band gap effects. Test results showed the 2D periodic foundation can effectively reduce the response of the upper structure for excitations with frequencies within the frequency band gaps. When the experimental and the finite element analysis results are compared, they agree well with each other, indicating that 2D periodic foundation is a feasible way of reducing seismic vibrations.

Application of 3D Laser Scanning Technology in Complex Rock Foundation Design

Junjie, Ma; Dan, Lu; Zhilong, Liu

2017-12-01

Taking the complex landform of Tanxi Mountain Landscape Bridge as an example, the application of 3D laser scanning technology in the mapping of complex rock foundations is studied in this paper. A set of 3D laser scanning technologies are formed and several key engineering problems are solved. The first is 3D laser scanning technology of complex landforms. 3D laser scanning technology is used to obtain a complete 3D point cloud data model of the complex landform. The detailed and accurate results of the surveying and mapping decrease the measuring time and supplementary measuring times. The second is 3D collaborative modeling of the complex landform. A 3D model of the complex landform is established based on the 3D point cloud data model. The super-structural foundation model is introduced for 3D collaborative design. The optimal design plan is selected and the construction progress is accelerated. And the last is finite-element analysis technology of the complex landform foundation. A 3D model of the complex landform is introduced into ANSYS for building a finite element model to calculate anti-slide stability of the rock, and provides a basis for the landform foundation design and construction.

Three dimensional periodic foundations for base seismic isolation

International Nuclear Information System (INIS)

Yan, Y; Mo, Y L; Cheng, Z; Shi, Z; Menq, F; Tang, Y

2015-01-01

Based on the concept of phononic crystals, periodic foundations made of periodic materials are investigated in this paper. The periodic foundations can provide low frequency band gaps, which cover the main frequency ranges of seismic waves. Therefore, the periodic foundations are able to protect the upper structures during earthquake events. In this paper, the basic theory of three dimensional periodic foundations is studied and the finite element method was used to conduct the sensitivity study. A simplified three-dimensional periodic foundation with a superstructure was tested in the field and the feasibility of three dimensional periodic foundations was proved. The test results showed that the response of the upper structure with the three dimensional periodic foundation was reduced under excitation waves with the main frequency falling in the attenuation zones. The finite element analysis results are consistent with the experimental data, indicating that three dimensional periodic foundations are a feasible way of reducing seismic vibrations. (paper)

Foundation Networks and American Hegemony

Directory of Open Access Journals (Sweden)

Inderjeet Parmar

2012-02-01

Full Text Available The major American foundations constructed and sustained the rich texture of cooperative social, intellectual and political relations between key actors and institutions supportive of specific modes of thought that promoted US hegemony. Foundations also fostered and developed the attractive power-knowledge networks that not only radiated intellectual influence but also attracted some of the most creative minds. Finally, liberal internationalist foundations fostered globalism even when the American state was ‘isolationist’, and when US influence abroad unwelcome. Their significance in American hegemony building lay in their sustained, long-term cooperative relationship with the American state through which they helped build national, international and global institutions and networks. The latter process evidences the most significant impact of US foundations – the building of the domestic and international infrastructure for liberal internationalism which has transformed into a kind of “social neoliberalism”. Theoretical conclusions follow from these claims: the sustained and deep cooperation between the state and foundations suggests that we must revise our views of “how power works” in the United States and therefore influences its foreign relations. Therefore, the article shows that elite networks, consisting of state officials and private citizens are powerful means by which foreign policy shifts may be prepared, elite and mass opinion primed and mobilised, new consensus built, ‘old’ forces marginalised, and US hegemony constructed.

Foundation heat transfer analysis for buildings with thermal piles

International Nuclear Information System (INIS)

Almanza Huerta, Luis Enrique; Krarti, Moncef

2015-01-01

Highlights: • A numerical transient thermal model for thermo-active foundations is developed. • Thermal interactions between thermal piles and building foundations are evaluated. • A simplified analysis method of thermal interactions between thermal piles and building foundations is developed. - Abstract: Thermal piles or thermo-active foundations utilize heat exchangers embedded within foundation footings to heat and/or cool buildings. In this paper, the impact of thermal piles on building foundation heat transfer is investigated. In particular, a simplified analysis method is developed to estimate the annual ground-coupled foundation heat transfer when buildings are equipped with thermal piles. First, a numerical analysis of the thermal performance of thermo-active building foundations is developed and used to assess the interactions between thermal piles and slab-on-grade building foundations. The impact of various design parameters and operating conditions is evaluated including foundation pile depth, building slab width, foundation insulation configuration, and soil thermal properties. Based on the results of a series of parametric analyses, a simplified analysis method is presented to assess the impact of the thermal piles on the annual heat fluxes toward or from the building foundations. A comparative evaluation of the predictions of the simplified analysis method and those obtained from the detailed numerical analysis indicated good agreement with prediction accuracy lower than 5%. Moreover, it is found that thermal piles can affect annual building foundation heat loss/gain by up to 30% depending on foundation size and insulation level

Moral foundations vignettes: a standardized stimulus database of scenarios based on moral foundations theory.

Research on the emotional, cognitive, and social determinants of moral judgment has surged in recent years. The development of moral foundations theory (MFT) has played an important role, demonstrating the breadth of morality. Moral psychology has responded by investigating how different domains of moral judgment are shaped by a variety of psychological factors. Yet, the discipline lacks a validated set of moral violations that span the moral domain, creating a barrier to investigating influences on judgment and how their neural bases might vary across the moral domain. In this paper, we aim to fill this gap by developing and validating a large set of moral foundations vignettes (MFVs). Each vignette depicts a behavior violating a particular moral foundation and not others. The vignettes are controlled on many dimensions including syntactic structure and complexity making them suitable for neuroimaging research. We demonstrate the validity of our vignettes by examining respondents' classifications of moral violations, conducting exploratory and confirmatory factor analysis, and demonstrating the correspondence between the extracted factors and existing measures of the moral foundations. We expect that the MFVs will be beneficial for a wide variety of behavioral and neuroimaging investigations of moral cognition.

Secondary foundation species as drivers of trophic and functional diversity: evidence from a tree-epiphyte system.

Science.gov (United States)

Angelini, Christine; Silliman, Brian R

2014-01-01

Facilitation cascades arise where primary foundation species facilitate secondary (dependent) foundation species, and collectively, they increase habitat complexity and quality to enhance biodiversity. Whether such phenomena occur in nonmarine systems and if secondary foundation species enhance food web structure (e.g., support novel feeding guilds) and ecosystem function (e.g., provide nursery for juveniles) remain unclear. Here we report on field experiments designed to test whether trees improve epiphyte survival and epiphytes secondarily increase the number and diversity of adult and juvenile invertebrates in a potential live oak-Tillandsia usneoides (Spanish moss) facilitation cascade. Our results reveal that trees reduce physical stress to facilitate Tillandsia, which, in turn, reduces desiccation and predation stress to facilitate invertebrates. In experimental removals, invertebrate total density, juvenile density, species richness and H' diversity were 16, 60, 1.7, and 1.5 times higher, and feeding guild richness and H' were 5 and 11 times greater in Tillandsia-colonized relative to Tillandsia-removal limb plots. Tillandsia enhanced communities similarly in a survey across the southeastern United States. These findings reveal that a facilitation cascade organizes this widespread terrestrial assemblage and expand the role of secondary foundation species as drivers of trophic structure and ecosystem function. We conceptualize the relationship between foundation species' structural attributes and associated species abundance and composition in a Foundation Species-Biodiversity (FSB) model. Importantly, the FSB predicts that, where secondary foundation species form expansive and functionally distinct structures that increase habitat availability and complexity within primary foundation species, they generate and maintain hot spots of biodiversity and trophic interactions.

Full Text Available The Foundation of Ilija Milosavljević Kolarac (also known as Kolarac Foundation; in Serbian: Kolarčeva zadužbina was established simultaneously with the development of the most important modern cultural institutions in Serbia in the 19th century. The quality and diversity of the program, the ability to recognize important topics in the current time, as well as preservation of the old and encouragement of new ideas in almost all domains of art and science have contributed to its unquestionable reputation throughout the region. However, there have been no significant academic attempts to approach its work analytically and, in particular, its audience. The aim of this paper is to give an overview of the work of Kolarac Foundation by presenting the origin and history of the institution, followed by an analysis of the program of all its activities in the first ten seasons of the new millennium. The central part of the paper is an analysis of its cultural activity in the given period. Finally, by using empirical data, the music audence of Great Hall (Velika Dvorana of Kolarac Foundation is profiled through its basic socio-demographic characteristics and music practices. The music audience mainly consisted of women, highly educated professionals with a high material standard. The share of the oldest and those from 21 to 30 years old is the highest and, at the same time, equal. This audience is authentically fond of music, with no exceptions at all. Its members listen to music on everyday basis, and they were attending concerts in the year before the investigation. They find music to be an inevitable part of their lives, and cannot imagine emotional expression or making friendships without it. Finally, they sincerely like coming to Kolarac Foundation since they find it to be a place that has all the positive treats of a good cultural institution.

Wronski's Foundations of Mathematics.

Science.gov (United States)

Wagner, Roi

2016-09-01

Argument This paper reconstructs Wronski's philosophical foundations of mathematics. It uses his critique of Lagrange's algebraic analysis as a vignette to introduce the problems that he raised, and argues that these problems have not been properly appreciated by his contemporaries and subsequent commentators. The paper goes on to reconstruct Wronski's mathematical law of creation and his notions of theory and techne, in order to put his objections to Lagrange in their philosophical context. Finally, Wronski's proof of his universal law (the expansion of a given function by any series of functions) is reviewed in terms of the above reconstruction. I argue that Wronski's philosophical approach poses an alternative to the views of his contemporary mainstream mathematicians, which brings up the contingency of their choices, and bridges the foundational concerns of early modernity with those of the twentieth-century foundations crisis. I also argue that Wronski's views may be useful to contemporary philosophy of mathematical practice, if they are read against their metaphysical grain.

Evolution of power plant foundations in Nova Scotia

2009-07-01

Many thermal steam plants in Nova Scotia, including the first 3 units Dartmouth's Tufts Cove Generating Station, were constructed on bedrock and near the sea for easy access to cooling water. Major equipment foundations such as turbine/condenser foundations, boiler feed pump foundations and fan foundations are concrete block foundations that are designed to withstand the heavy equipment and environmental loads imposed throughout the service-life of the plant. This paper discussed the rationale for choosing different types of foundations at the 5 power generating units at the Tufts Cove Generating Station. Due to the presence of boulders, pipe piles were installed in drilled holes in 1995 for the unit 2 precipitator foundation. In 2005, micro-piles were installed for unit 1 and 3 precipitators because they were relatively non-protrusive for the congested urban site that was full of buried structures and services. Similarly, for the unit 4 and 5 sound wall foundations, the high resistance capacities for both downward and uplift loads of the micro-piles embedded into the bedrock proved to be very valuable. These tall wall structures are subject to very high wind loads and were constructed at a geotechnically challenged site. Good geotechnical investigation and consultation was shown to be the basis for good design and construction of foundation works. It was concluded that the lessons learned at Tufts Cove can be applied to other similar foundation designs. 7 refs., 10 figs.

The curator/patron: Foundations and contemporary art

Directory of Open Access Journals (Sweden)

Rebecca Coates

2008-12-01

Full Text Available This article addresses the role of private foundations in commissioning site-specific ephemeral art works: contemporary art projects of a temporary nature that are realised outside of public institutions. Though small in number, I argue that the private individuals creating and managing private foundations of this nature demonstrate a new form of patronage, creating in the process a new role of ‘curator/patron’. Equally, this process of realisation reflects the changing needs of contemporary art practice. Work of this scale and ambition would increasingly not be possible without the vision, perseverance and funding of these kinds of foundation. In Australia, this trend is demonstrated by two foundations: Kaldor Art Projects, and their commissioning of works by artists such as Christo and Jeanne-Claude, Gilbert & George and Jeff Koons; and the more recently formed Sherman Contemporary Art Foundation, whose first project was with Chinese artist Ai Weiwei. In this article, these examples are placed within the broader international context of foundation models such as Artangel, UK, Fondazione Nicola Trussardi, Milan, and The Public Art Fund, New York.

This paper attempts to place industrial foundations (IFs in the following; similar to trusts) in the tax system. An industrial foundation is a private foundation that holds a voting majority in a joint stock corporation. These IFs are probably more prevalent in Denmark than in any other country......? The paper explores the implications of treating IFs as high‐income earners (wealthy individuals) and draws the conclusion that in the current system, IFs are very leniently taxed relative to that benchmark. Lenient tax treatment relative to the norm is regularly interpreted as tax expenditures; the usual...

Energy Efficiency and Renewable Energy Research, Development, and Deployment in Meeting Greenhouse Gas Mitigation Goals. The Case of the Lieberman-Warner Climate Security Act of 2007 (S. 2191)

The U.S. federal government is considering actions to reduce greenhouse gas emissions. Renewable energy and energy efficiency technologies could help reduce greenhouse gas emissions, so the cost of these technologies could significantly influence the overall cost of meeting greenhouse gas limits. This paper examines the potential benefit of reduced technology cost by analyzing the case of the Lieberman-Warner Climate Security Act of 2007 (S.2191). This act had a goal of reducing national carbon emissions in 2050 to levels 72 percent below 2006 emission levels. In April 2008, the U.S. Department of Energy, Energy Information Administration (EIA) published an analysis of the effects of S.2191 on the U.S. energy sector. This report presents a similar analysis: both analyses examined the impacts of S.2191, and both used versions of the National Energy Modeling System. The analysis reported here used modified technology assumptions to reflect U.S. Department of Energy, Office of Energy Efficiency and Renewable Energy (EERE) program goals. The results show that achieving EERE program goals could reduce the cost of meeting greenhouse gas limits, reduce the cost of renewable electricity generation and biofuels, and reduce energy intensity.

Discrete singular convolution method for the analysis of Mindlin plates on elastic foundations

International Nuclear Information System (INIS)

Civalek, Omer; Acar, Mustafa Hilmi

2007-01-01

The method of discrete singular convolution (DSC) is used for the bending analysis of Mindlin plates on two-parameter elastic foundations for the first time. Two different realizations of singular kernels, such as the regularized Shannon's delta (RSD) kernel and Lagrange delta sequence (LDS) kernel, are selected as singular convolution to illustrate the present algorithm. The methodology and procedures are presented and bending problems of thick plates on elastic foundations are studied for different boundary conditions. The influence of foundation parameters and shear deformation on the stress resultants and deflections of the plate have been investigated. Numerical studies are performed and the DSC results are compared well with other analytical solutions and some numerical results

CALCULATION OF FOUNDATIONS WITH CIRCULAR (CLOSED IN-PLANE SHAPES

Directory of Open Access Journals (Sweden)

L. S. Khasenevich

2017-01-01

Full Text Available It has been found that four reinforced concrete flue stacks being constructed in late 80-ies and early in 90-ies of the 20th century and being operated at various thermal power stations show practically no settlement, and this fact is not taken into account by any applicable regulatory documents. Foundations of these stacks were designed at the same time and they have been protected by patents of Russian Federation and Republic of Belarus. They represent circular bases made of reinforced concrete piles buried tightly together and forming so-called “slurry wall” with common monolithic reinforced concrete grillage. The grillage presents a direct extension of the stack shaft. One of these stacks has been built in Russia, and three – in Belarus. Due to significant differences in soil conditions and loads in each case, it is a fair assumption to say about regularity of the observed phenomenon. Notwithstanding the fact that circular foundations significantly decrease steel and concrete consumption, construction period and labour input, they have not yet received adequate attention from the side of scientific community and designers. While considering specific examples of the constructed stacks the paper reveals an opportunity to apply calculations which efficiently use passive soil resistance. The presented calculations and designs of the existing foundations make it possible to assess probability of the proposed methodology for the foundations which are analogous in design and which have closed in-plane structure not only for industrial buildings and structures.

Research on horizontal displacement monitoring method of deep foundation pit based on laser projecting sensing technology

Science.gov (United States)

Liu, Peng; Xie, Shulin; Zhang, Lixiao; Zhou, Guangyi; Zhao, Xuefeng

2018-03-01

A certain level of horizontal displacement will occur during excavation or subsequent construction of deep foundation pit. If the support is improper and the horizontal displacement of the foundation pit is too large, it will cause collapse and even affect the buildings around the foundation pit, which will endanger people's life and property. Therefore, the horizontal displacement monitoring of deep foundation pit becomes more and more important. At present, the electronic total station is often used to monitor the horizontal displacement of the foundation pit, but this monitoring method is expensive, prone to accidental errors, and can not be used for real-time monitoring. Therefore, a method of monitoring the horizontal displacement of deep foundation pit by using laser projection sensing technique is proposed in this paper. The horizontal displacement of the foundation pit is replaced by the displacement of the laser spot emitted by the laser, and the horizontal displacement of the foundation pit can be obtained by identifying the displacement of the laser spot projected on the screen. A series of experiments show that the accuracy of this monitoring method meets the engineering requirements and greatly reduces the cost, which provides a new technology for the displacement monitoring of deep foundation pit.

Becoming a (male foundation phase teacher: A need in South African schools?

Nontokoza Mashiya

2014-12-01

Full Text Available This paper reports on a case study of male foundation phase pre-service students who were among the first cohort to specialise in the foundation phase since the inception of the programme at one South African university. The students reported on their experiences of teaching in a female-dominated field and their views about their preparedness to teach in the field. This qualitative study is interpretive in nature. Using purposive sampling, eighteen students were sampled from a population of twenty. Data was generated through focus group interviews and then analysed and categorised. The patterns across categories showed that the pre-service teachers had faced an unwelcoming environment in the schools at the outset, but that this changed over time. Some parents were negative about male teachers in the foundation phase. However, the pre-service teachers were able to work hard and show that they can work with foundation phase learners. The study concluded that male students who enter foundation phase teacher education programmes need a lot of encouragement to boost their self-confidence and to realise the important role they can play in working with young children in a country where many young learners grow up in fatherless homes.

Radon reduction in wood foundation system

Radon, an issue of growing concern to the building industry. Silently, invisibly, it invades existing structures as it will future foundation structures. This paper addresses the nature and causes of radon, and cost-effective prevention and retrofit techniques used for wood foundation systems. Radon also can enter homes with foundations that use the under-floor as an air distribution system. These building practices will be shown; even materials used in construction may release radon, for example, this may be a problem in a house that has a solar heating system in which its heat is stored in large beds of stone. Stone is most often used in wood foundation construction. The common radon entry points will be looked at, and the latest prevention techniques will be illustrated, such as natural and forced ventilation, sealing major radon sources and entry routes, and sub-slab and sump crock ventilations

1992-09-30

For the purpose of studying the pile foundation response in liquefiable soil deposit during earthquakes, a centrifugal loading system is employed which can reproduce the stress conditions of the soil in the actual ground, and earthquake wave vibration tests are performed in dry and saturated sand layers using a pile foundation model equipped with 4 piles. In addition, the result of the tests is analyzed by simulation using an analytic method for which effective stress is taken into consideration to investigate the effectiveness of this analytical model. It is clarified from the result of the experiments that the bending moment of the pile and the response characteristics of the foundation in the pile foundation response in saturated sand are greatly affected by the longer period of acceleration wave form of the ground and the increase in the ground displacement due to excess pore water pressure buildup. It is shown that the analytical model of the pile foundation/ground system is appropriate, and that this analytical method is effective in evaluating the seismic response of the pile foundation in nonlinear liquefiable soil. 23 refs., 21 figs., 3 tabs.

Interacting with public authorities and advocating end-stage renal disease (ESRD) patients' rights are essential services of this non-governmental organization (NGO). Over the last 30 years, keeping with the trend of chronic kidney disease (CKD) in the country, the foundation raised awareness in the population for this condition and prepared an activity road map by using statistical facts and data. Goals were set keeping in mind the local culture and traditions, debating on them with colleagues, PR agencies, and other experts in this field. The best strategy embrace the society, and all activities are made as cost-effective as possible in keeping with a tight budget. Various communication channels, especially social media, are used to communicate the message to the public, always keeping in mind that such messages are to be succinct and precise. Every effort is taken to make our foundation reliable and trustworthy in the eyes of the public at large. Reliability, credibility, and trust are the key success corner stones of our NGO. Every opportunity is taken to capitalize on participation of celebrities and real stories of people. Testimonies of real ESRD patients are always interesting and can touch the hearts of the rest of the population.

Stochastic response of rigid foundations

International Nuclear Information System (INIS)

Pais, A.L.; Kausel, E.

1986-01-01

While the study of Kinematic Interaction effects calls, in general, for advanced analytical and numerical techniques, an excellent approximation was proposed recently by Iguchi. This approximation was used by the authors to analyze embedded foundations subjected to spatially random SH-wave fields, i.e., motions that exhibit some degree of incoherence. The wave fields considered ranged from perfectly coherent motions (resulting from seismic waves arriving from a single direction) to chaotic motions resulting from waves arriving simultaneously from all directions. Additional parameters considered were the shape of the foundation (cylindrical, rectangular) and the degree of embedment. It was found that kinematic interaction usually reduces the severity of the motions transmitted to the structure, and that incoherent motions do not exhibit the frequency selectivity (i.e., narrow valleys in the foundation response spectra) that coherent motions do

Sharapov, R.; Lodigina, N.

2017-07-01

Karst processes greatly complicate the construction and operation of buildings and structures. Due to the karstic deformations at different times there have been several major accidents, which analysis showed that in all cases the fundamental errors committed at different stages of building development: site selection, engineering survey, design, construction or operation of the facilities. Theory analysis of beams on elastic foundation is essential in building practice. Specialist engineering facilities often have to resort to multiple designing in finding efficient forms of construction of these facilities. In work the calculation of stresses in cross-sections of the strip foundation evenly distributed load in the event of karst. A comparison of extreme stress in the event of karst and without accounting for the strip foundation as a beam on an elastic foundation.

Solid foundations are integral important part of any structures. Obtaining accurate and timely information on the integrity of structural foundations is essential for project progress and success. Cross-hole sonic method has been widely accepted for quality assurance and quality control on projects with deep foundations, and to assess the integrity of other civil engineering structures. Under the framework of the basic VAEC project (2003) and project VIE/8/013, the Cross-hole sonic method (CHM) was evaluated at Center for Nuclear Techniques, Hochiminh City (CNT). Background information on principle and general description of the method as is typically applied in the evaluation of deep foundations are also summarized. A suitable experimental model of the shaft foundations was prepared, where the artificial defects can be controlled for the Cross-hole sonic logging was conducted by measuring the propagation time of ultrasonic signals between two probes in vertical holes in a shaft. The purpose of the test program is to evaluate the ability of the cross-hole sonic method to identify the defects present in the experimental model, to evaluate the capabilities of the method and the equipped system Cs-97, to improve the presentation of test results to meet requirements for interpreting the quality of drilled shafts by processing the data of Cs-97. The cross-hole sonic testing program is describe. Summarizes the results and analysis of the cross-hole sonic logging are presented to highlight both the applicability and limitations of the method. The cross-hole sonic logging evaluation is a valuable non-destructive method in assessing the integrity of deep foundations. The cross-hole sonic logging tests successfully determined the location and extent of the built-in defects on experimental model shaft. Minimum sizes of defects can be detected were about ≥ 10 cm Cs-97. Effects of the directions, detectable sizes and natures of defects were studied. The apparent velocities

Foundation calculation for buildings and structures with two elastic characteristics of the foundation using features of Fourier transformsfor finite functions

Directory of Open Access Journals (Sweden)

Kurbatskiy Evgeniy Nikolaevich

2014-01-01

Full Text Available The problem of a beam resting on elastic foundation often occurs in the analysis of building, geotechnical, highway, and railroad structures. Its solution demands modeling of the mechanical behavior of the beam, the mechanical behavior of the soil as elastic subgrade and the form of interaction between the beam and the soil. The oldest, most famous and most frequently used mechanical model is the one devised by Winkler (1867, in which the beam-supporting soil is modeled as a series of closely spaced, mutually independent, linear elastic vertical springs, which, evidently, provide resistance in direct proportion to the deflection of the beam.The solution is presented for the problem of an Euler–Bernoulli beam supported by an infinite two-parameter Pasternak foundation. The beam is subjected to arbitrarily distributed or concentrated vertical loading along its length. Static response of a beam on an elastic foundation characterized by two parameters is investigated assuming, that the beam is subjected to external loads and two concentrated edge load. The governing equations of the problem are obtained and solved by pointing out that there is a concentrated edge foundation reaction in addition to a continuous foundation reaction along the beam axis in the case of complete contact in the foundation reactions of the two-parameter foundation model. The proposed method is based on the properties of Fourier transforms of the finite functions. Particular attention is paid to the problem, taking into account the deformation of soil areas outside the beam. The beam model with two foundation coefficients more realistically describes the behavior of strip footings under loading.

Full Text Available Raising of problem. In the construction of high-rise buildings with significant loads on foundations and bedding at the base of not rocky soils tend to use the most common pile foundation to reduce the deformation and correspond to regulations [1] on the maximum permissible deformation. Monitoring of the stress-strain state (SSS pile foundations constructed buildings shows the existing reserves of bearing capacity on the one hand - soil bases of the second group of limit states, on the other - the foundation of the first group of limit states by regulating the SSS foundation during construction and exploitation. Therefore, are increasingly using more progressive structure of foundations consisting of piles and of plate, as well as methods for their construction [2 - 10], however, in their design there are a number of disadvantages associated with the ambiguity of the application of methods for the calculation of such structures, which allows to do only partial conclusions and recommendations. Purpose. Is proposing the new structure of a plate-pile foundation, which overcomes the drawbacks of the existing design solutions and methods of consruction their, as well as is proposing an engineering method of a determination of basic parameters. Conclusion. Is proposes the new structure of a plate-pile foundation and the method of a determination of basic parameters his in the design of a soil base to the maximum permissible deformation Su buildings. Efficiency of application this type plate-pile foundation obtained by rational distribution resistance between a plate and piles, when under load from the building to the first work fully incorporated plate that allows maximum deformed for plate, and then the piles - due to of the hinge connection with the plate. Thus, depending on the maximum permissible deformation for buildings resistance of plate part of a full load of more than 50%, that significantly reduces the consumption of concrete.

1984-01-01

A general procedure for the determination of the spring constants and damping coeficientes which represent the foundation-structure interaction is presented. According to this procedure it is possible to determine the variation of the stiffness and damping with the frequency for flexible foundation slabs by employing the equivalent rigid slab concept. It is also possible to determine the distribution of the springs along the foundation. The results obtained for the reactor building of a NPP of 1300 MW PWR of KWU type taking into account the flexibility of the foundation slab is presented as an application example of this procedure.

A Comparative Analysis of Corporate and Independent Foundations

Directory of Open Access Journals (Sweden)

Justin Koushyar

2015-12-01

Full Text Available Notwithstanding some visible debates, systematic evidence about the implications of greater corporate involvement in the social sector is sparse. We provide some of this evidence by examining one channel of corporate influence within the nonprofit sector–company sponsorship of philanthropic foundations. Our analysis shows that corporate foundations raise more funds and distribute grants with lower overhead than similar independent (i.e., non-corporate foundations. However, their grantmaking is also more dispersed and less relational, and they tend to be governed by more ephemeral groups of officers and trustees. These findings suggest that corporate foundations benefit from having access to the resources of the companies that sponsor them but are constrained by their additional market-based motivations. The findings also update and refine what nonprofits might expect from corporate foundations relative to their more traditional independent counterparts.

Characterization of transient groundwater flow through a high arch dam foundation during reservoir impounding

Directory of Open Access Journals (Sweden)

Yifeng Chen

2016-08-01

Full Text Available Even though a large number of large-scale arch dams with height larger than 200 m have been built in the world, the transient groundwater flow behaviors and the seepage control effects in the dam foundations under difficult geological conditions are rarely reported. This paper presents a case study on the transient groundwater flow behaviors in the rock foundation of Jinping I double-curvature arch dam, the world's highest dam of this type to date that has been completed. Taking into account the geological settings at the site, an inverse modeling technique utilizing the time series measurements of both hydraulic head and discharge was adopted to back-calculate the permeability of the foundation rocks, which effectively improves the uniqueness and reliability of the inverse modeling results. The transient seepage flow in the dam foundation during the reservoir impounding was then modeled with a parabolic variational inequality (PVI method. The distribution of pore water pressure, the amount of leakage, and the performance of the seepage control system in the dam foundation during the entire impounding process were finally illustrated with the numerical results.

The effects of foundation deformation on alignment in turbine generator sets have gained significance with the transition to modern units at the limit of design possibilities. It is therefore necessary to obtain clarification about the remaining operational variations of turbine foundations. Static measurement programmes, which cover both deformation processes as well as individual conditions of deformation are described in the paper. In order to explain the deformations measured structural engineering model calculations are being undertaken which indicate the effect of limiting factors. (orig.) [de

Practical Soil-Shallow Foundation Model for Nonlinear Structural Analysis

Directory of Open Access Journals (Sweden)

Moussa Leblouba

2016-01-01

Full Text Available Soil-shallow foundation interaction models that are incorporated into most structural analysis programs generally lack accuracy and efficiency or neglect some aspects of foundation behavior. For instance, soil-shallow foundation systems have been observed to show both small and large loops under increasing amplitude load reversals. This paper presents a practical macroelement model for soil-shallow foundation system and its stability under simultaneous horizontal and vertical loads. The model comprises three spring elements: nonlinear horizontal, nonlinear rotational, and linear vertical springs. The proposed macroelement model was verified using experimental test results from large-scale model foundations subjected to small and large cyclic loading cases.

Rethinking foundations of language from a multidisciplinary perspective.

Gong, Tao; Shuai, Lan; Wu, Yicheng

2018-04-21

The issue of language foundations has been of great controversy ever since it was first raised in Lenneberg's (1967) monograph Biological Foundations of Language. Based on a survey of recent findings relevant to the study of language acquisition and evolution, we propose that: (i) the biological predispositions for language are largely domain-general, not necessarily language-specific or human-unique; (ii) the socio-cultural environment of language serves as another important foundation of language, which helps shape language components, induce and drive language shift; and (iii) language must have coevolved with the cognitive mechanisms associated with it through intertwined biological and cultural evolution. In addition to theoretical issues, this paper also evaluates the primary approaches recently joining the endeavor of studying language foundations and evolution, including human experiments and computer simulations. Most of the evidence surveyed in this paper comes from a variety of disciplines, and methodology therein complements each other to form a global picture of language foundations. These reflect the complexity of the issue of language foundations and the necessity of taking a multidisciplinary perspective to address it. Copyright © 2018 Elsevier B.V. All rights reserved.

Influence of negative interest rates on endowements and foundations functioning

Directory of Open Access Journals (Sweden)

Nikolić Dušan Ž.

2015-01-01

Full Text Available Negative interest rate exists in the case when on the basis of the deposit contract a deponent is obliged to pay to a depository (a bank a reimbursement for the money keeping (paying to save. The scientific literature indicates that the legal regulation on endowments and foundations in a vast number of countries is based on the presumption that interest rates cannot be negative and that we are encountering the phenomenon of which we have limited knowledge. The introduction of negative interest rates, thus, could endanger the functioning, if not the subsistence of some endowments and foundations. The vulnerable social groups could, thereby, be especially affected. The Law on Endowments and Foundations of the Republic of Serbia enshrines that the endowments' capital shall not fall under the minimum capital assets of30.000 EUR recalculated in dinars based on the middle exchange rate of the National Bank of Serbia on the day of establishment. Apart from that, a founder may in the Articles of Association determine the minimum value below which the capital assets of endowment may not be reduced, which may not be lower of the minimum assets value set by the Law. In Serbia negative interest rates could aggravate, and throughout the time, even prevent the accomplishment of aims of endowments and foundations which for the operation of their activities may use only the interest yields and not the means of capital assets above the legal minimum. Some endowments could even cease to exist due to the diminishment of their minimum capital assets which entirely consist of the money deposited in the banks. The Article indicates the need for reconsidering the legal norms currently in force and that the transformation of certain legal institutes shall timely commence, whereby their systematic and social functions shall be regarded, as well as the need for introducing a streamlined corrective mechanisms with the aim of protecting interests of the weaker party in

Far-field dynamic behavior of a half-space under an inertial strip foundation subjected to a time-harmonic force

Directory of Open Access Journals (Sweden)

M. Dehestani

Full Text Available Recent research works demonstrated that the interaction between the loads and the carrying structure's boundary which is related to the inertia of the load is an influential factor on the dynamic response of the structure. Although effects of the inertia in moving loads were considered in many works, very few papers can be found on the inertial effects of the stationary loads on structures. In this paper, an elastodynamic formulation was employed to investigate the dynamic response of a homogeneous isotropic elastic half-space under an inertial strip foundation subjected to a time-harmonic force. Fourier integral transformation was used to solve the system of Poisson-type partial differential equation considering the boundary conditions and the inertial effects. Steepest descent method was employed to obtain the approximate far-field displacements and stresses. A numerical example is presented to illustrate the methodology and typical results.

Stochastic analysis of uncertain thermal characteristic of foundation soils surrounding the crude oil pipeline in permafrost regions

2016-01-01

Highlights: • The influence of stochastic properties and conditions on permafrost foundation was investigated. • A stochastic analysis for the uncertain thermal characteristic of crude oil pipe is presented. • The mean temperature and standard deviation of foundation soils are obtained and analyzed. • Average standard deviation and maximum standard deviation of foundation soils increase with time. - Abstract: For foundation soils surrounding the crude oil pipeline in permafrost regions, the soil properties and the upper boundary conditions are stochastic because of complex geological processes and changeable atmospheric environment. The conventional finite element analysis of thermal characteristics for crude oil pipeline is always deterministic, rather than taking stochastic parameters and conditions into account. This study investigated the stochastic influence of an underground crude oil pipeline on the thermal stability of the permafrost foundation on the basis of a stochastic analysis model and the stochastic finite element method. A stochastic finite element program is compiled by Matrix Laboratory (MATLAB) software, and the random temperature fields of foundation soils surrounding a crude oil pipeline in a permafrost region are obtained and analyzed by Neumann stochastic finite element method (NSFEM). The results provide a new way to predict the thermal effects of the crude oil pipeline in permafrost regions, and it shows that the standard deviations in temperature increase with time when considering the stochastic effect of soil properties and boundary conditions, which imply that the results of conventional deterministic analysis may be far from the true value, even if in different seasons. It can improve our understanding of the random temperature field of foundation soils surrounding the crude oil pipeline and provide a theoretical basis for actual engineering design in permafrost regions.

Seven Foundational Principles of Population Health Policy.

Bhattacharya, Dru; Bhatt, Jay

2017-10-01

In 2016, Keyes and Galea issued 9 foundational principles of population health science and invited further deliberations by specialists to advance the field. This article presents 7 foundational principles of population health policy whose intersection with health care, public health, preventive medicine, and now population health, presents unique challenges. These principles are in response to a number of overarching questions that have arisen in over a decade of the authors' collective practice in the public and private sectors, and having taught policy within programs of medicine, law, nursing, and public health at the graduate and executive levels. The principles address an audience of practitioners and policy makers, mindful of the pressing health care challenges of our time, including: rising health-related expenditures, an aging population, workforce shortages, health disparities, and a backdrop of inequities rooted in social determinants that have not been adequately translated into formal policies or practices among the key stakeholders in population health. These principles are meant to empower stakeholders-whether it is the planner or the practitioner, the decision maker or the dedicated caregiver-and inform the development of practical tools, research, and education.

SUSTAINABLE CONCRETE FOR WIND TURBINE FOUNDATIONS.

Energy Technology Data Exchange (ETDEWEB)

BERNDT,M.L.

2004-06-01

The use of wind power to generate electricity continues to grow, especially given commitments by various countries throughout the world to ensure that a significant percentage of energy comes from renewable sources. In order to meet such objectives, increasingly larger turbines with higher capacity are being developed. The engineering aspects of larger turbine development tend to focus on design and materials for blades and towers. However, foundations are also a critical component of large wind turbines and represent a significant cost of wind energy projects. Ongoing wind research at BNL is examining two areas: (a) structural response analysis of wind turbine-tower-foundation systems and (b) materials engineering of foundations. This work is investigating the dynamic interactions in wind turbine systems, which in turn assists the wind industry in achieving improved reliability and more cost efficient foundation designs. The results reported herein cover initial studies of concrete mix designs for large wind turbine foundations and how these may be tailored to reduce cost and incorporate sustainability and life cycle concepts. The approach taken was to investigate material substitutions so that the environmental, energy and CO{sub 2}-impact of concrete could be reduced. The use of high volumes of ''waste'' materials in concrete was examined. These materials included fly ash, blast furnace slag and recycled concrete aggregate. In addition, the use of steel fiber reinforcement as a means to improve mechanical properties and potentially reduce the amount of bar reinforcement in concrete foundations was studied. Four basic mixes were considered. These were: (1) conventional mix with no material substitutions, (2) 50% replacement of cement with fly ash, (3) 50% replacement of cement with blast furnace slag and (4) 25% replacement of cement with fly ash and 25% replacement with blast furnace slag. Variations on these mixes included the addition of 1

In this paper, Improved Moving Element Method (IMEM) is used to analyze the dynamic response of Euler-Bernoulli beam structures on the dynamic foundation model subjected to the moving load. The effects of characteristic foundation model parameters such as Winkler stiffness, shear layer based on the Pasternak model, viscoelastic dashpot and characteristic parameter of mass on foundation. Beams are modeled by moving elements while the load is fixed. Based on the principle of the publicly virtual balancing and the theory of moving element method, the motion differential equation of the system is established and solved by means of the numerical integration based on the Newmark algorithm. The influence of mass on foundation and the roughness of the beam surface on the dynamic response of beam are examined in details.

1983-01-01

Comprehensive calculations were made to examine a foundation plate under static load with non-linear material behaviour. In particular, deformation and crack behaviour of the plate were observed. The calculations hereunder, made to calculate the time of rupture of the plate with the foundation exposed to high temperatures, with and without cavity formation, prove that high temperatures are not as relevant as the melt-down of the layers of armour on top of the middle of the plate. The consequences of this survey are: to protect the top armour of the plate centre and not to use it as support for any structural components. This free space could then be used to instal said multi-layer plate. (orig./HP) [de

Is Rorty’s Neopragmatism the “Real” Foundation of Medical Ethics: a Search for Foundational Principles

Science.gov (United States)

Branch, William T

2006-01-01

Principlism, the predominate approach to bioethics, has no foundational principles. This absence of foundations reflects the general intellectual climate of postmodern relativism. Even America’s foremost public philosopher, Richard Rorty, whose pragmatism might suggest a philosophy of commonsense, seems to be swimming in the postmodern swamp. Alternatively, principlism’s architects, Beauchamp and Childress, suggest a constantly evolving reflective equilibrium with some basis in common morality as a workable framework for twenty-first century bioethics. The flaw in their approach is failure to conform to real doctors’ and patients’ experiences. Real doctors adopt a scientific paradigm that assumes an objective reality. Patients experience real suffering and seek effective cures, treatments, palliation and solace. The foundation of medical ethics should be that doctors altruistically respond to their patients’ suffering using scientifically acceptable modalities. Compassion, caring, and respect for human dignity are needed as guides in addition to justice, beneficence, nonmaleficence and respect for autonomy. PMID:18528478

Full Text Available This paper focuses on the evaluation standards of factor of safety for foundation stability analysis. The problem of foundation stability is analyzed via the methods of risk analysis of engineering structures and reliability-based design, and the factor of safety for foundation stability is determined by using bearing capacity safety-factor method (BSFM and strength safety-factor method (SSFM. Based on a typical example, the admissible factors of safety were calibrated with a target reliability index specified in relevant standards. Two safety criteria and their standards of bearing capacity of foundation for these two methods (BSFM and SSFM were established. The universality of the safety criteria and their standards for foundation reliability was verified based on the concept of the ratio of safety margin (RSM.

Impact loads on beams on elastic foundations

International Nuclear Information System (INIS)

Kameswara Rao, N.S.V.; Prasad, B.B.

1975-01-01

Quite often, complex structural components are idealised as beams in engineering analysis and design. Also, equations governing the responses of shallow shells are mathematically equivalent to the equations governing the responses of beams on elastic foundations. Hence with possible applications in several technical disciplines, the behaviour of beams on elastic foundations subjected to impact loads is studied in detail in the present investigation both analytically and experimentally. The analytical methods include analysis and energy method. The effect of foundation parameters (stiffness, and damping constants) on the dynamic responses of the beam-foundation system has been analysed. In modal analysis, the free-vibration equation has been solved by replacing the applied impulse by suitable initial conditions and the solution has been obtained as the linear combination of an infinite sequence of discrete eigen-vectors. In the energy method, the beam-foundation system is treated to be under forced vibrations and the forcing function has been obtained using the Hertz's law of impact. In the case of free-free end conditions of the beam, the rigid body modes and the elastic modes have been superposed to obtain the total response. The responses predicted using modal analysis are higher than those obtained using energy method. From the present study it is observed that model analysis is preferable to energy method. (Auth.)

Development and Application of a Numerical Framework for Improving Building Foundation Heat Transfer Calculations

Science.gov (United States)

Kruis, Nathanael J. F.

Heat transfer from building foundations varies significantly in all three spatial dimensions and has important dynamic effects at all timescales, from one hour to several years. With the additional consideration of moisture transport, ground freezing, evapotranspiration, and other physical phenomena, the estimation of foundation heat transfer becomes increasingly sophisticated and computationally intensive to the point where accuracy must be compromised for reasonable computation time. The tools currently available to calculate foundation heat transfer are often either too limited in their capabilities to draw meaningful conclusions or too sophisticated to use in common practices. This work presents Kiva, a new foundation heat transfer computational framework. Kiva provides a flexible environment for testing different numerical schemes, initialization methods, spatial and temporal discretizations, and geometric approximations. Comparisons within this framework provide insight into the balance of computation speed and accuracy relative to highly detailed reference solutions. The accuracy and computational performance of six finite difference numerical schemes are verified against established IEA BESTEST test cases for slab-on-grade heat conduction. Of the schemes tested, the Alternating Direction Implicit (ADI) scheme demonstrates the best balance between accuracy, performance, and numerical stability. Kiva features four approaches of initializing soil temperatures for an annual simulation. A new accelerated initialization approach is shown to significantly reduce the required years of presimulation. Methods of approximating three-dimensional heat transfer within a representative two-dimensional context further improve computational performance. A new approximation called the boundary layer adjustment method is shown to improve accuracy over other established methods with a negligible increase in computation time. This method accounts for the reduced heat transfer

Private foundations Global Health Philanthropy: the problem of conflicts of interest. Private foundations are in a position where they are granted several privileges and are very powerful and able to influence global health. A recent article published on Plos Medicine, analyzing five of the largest health foundations highlights the network of interests and conflicts. Many private health foundations have associations with private food and pharmaceutical corporations. In some instances, these corporations directly benefit from foundations grants, and foundations in turn are invested in the corporations to which they award these grants.

The Foundation Supernova Survey aims to provide a large, high-fidelity, homogeneous, and precisely calibrated low-redshift Type Ia supernova (SN Ia) sample for cosmology. The calibration of the current low-redshift SN sample is the largest component of systematic uncertainties for SN cosmology, and new data are necessary to make progress. We present the motivation, survey design, observation strategy, implementation, and first results for the Foundation Supernova Survey. We are using the Pan-STARRS telescope to obtain photometry for up to 800 SNe Ia at z ≲ 0.1. This strategy has several unique advantages: (1) the Pan-STARRS system is a superbly calibrated telescopic system, (2) Pan-STARRS has observed 3/4 of the sky in grizyP1 making future template observations unnecessary, (3) we have a well-tested data-reduction pipeline, and (4) we have observed ˜3000 high-redshift SNe Ia on this system. Here, we present our initial sample of 225 SN Ia grizP1 light curves, of which 180 pass all criteria for inclusion in a cosmological sample. The Foundation Supernova Survey already contains more cosmologically useful SNe Ia than all other published low-redshift SN Ia samples combined. We expect that the systematic uncertainties for the Foundation Supernova Sample will be two to three times smaller than other low-redshift samples. We find that our cosmologically useful sample has an intrinsic scatter of 0.111 mag, smaller than other low-redshift samples. We perform detailed simulations showing that simply replacing the current low-redshift SN Ia sample with an equally sized Foundation sample will improve the precision on the dark energy equation-of-state parameter by 35 per cent, and the dark energy figure of merit by 72 per cent.

FIELD INVESTIGATIONS OF PILED-RAFT FOUNDATIONS WITH SHORT-LENGTH CONIC PILES IN BUILDING AREAS OF MINSK

Directory of Open Access Journals (Sweden)

V. A. Sernov

2015-01-01

Full Text Available In recent time piled foundations are extensively applied due to an increase of storeys in buildings constructed in Minsk and load increment on the soil. Preference is given to this approach even in the case when relatively firm soil occurs in the top part of the foundation bed. In this case maximum usage of the foundation bed bearing capacity and reduction of foundation cost are considered as top-priority tasks for designers. One of the ways to increase the bearing capacity of piled foundations is the necessity to take into account resistance of foundation bed soil located under raft bottom. The raft as well as a shallow foundation is capable to transfer a significant part of building load into the soil. Such approach makes it possible to reduce a number of piles in the foundation or shorten their length. Then it results in shortening of the construction period and significant reduction in zero cycle. However up to the present moment reliable calculation methods that permit to take into account soil resistance in the raft base. An analysis of previous investigations on the matter executed by various researchers and a number of field investigations have been carried out with the purpose to develop the proposed methods.The paper presents results of field investigations on foundations consisting of short stamped tapered piles which are joined together with the help of the raft fragment. Strength and deformation characteristics of the bases are increasing while making such foundations in the fill-up soil. In this case the filled-up ground layer becomes a bearing layer both for piles and rafts as well. Improvement of high-plastic clay-bearing soil properties is ensured by ramming dry concrete mix under pile foot. The paper describes an experience on application of the piled-raft foundation in complicated engineering and geological conditions while constructing the Orthodox Church in Minsk.

Periodic materials-based vibration attenuation in layered foundations: experimental validation

International Nuclear Information System (INIS)

Xiang, H J; Shi, Z F; Wang, S J; Mo, Y L

2012-01-01

Guided by the recent advances in solid-state research in periodic materials, a new type of layered periodic foundation consisting of concrete and rubber layers is experimentally investigated in this paper. The distinct feature of this new foundation is its frequency band gaps. When the frequency contents of a wave fall within the range of the frequency band gaps, the wave, and hence its energy, will be weakened or cannot propagate through the foundation, so the foundation itself can serve as a vibration isolator. Using the theory of elastodynamics and the Bloch–Floquet theorem, the mechanism of band gaps in periodic composites is presented, and a finite element model is built to show the isolation characteristic of a finite dimensional periodic foundation. Based on these analytical results, moreover, a scaled model frame and a periodic foundation were fabricated and shake table tests of the frame on the periodic foundation were performed. Ambient, strong and harmonic vibration attenuations are found when the exciting frequencies fall into the band gaps. (fast track communication)

Full Text Available The difference in moral foundations between adults living in Western or Eastern countries is well-known, but there is lack of evidence about such difference in adolescence. We tested the hypothesis about cultural differences of moral foundations in Mongolian, Russian and German adolescents. As the methodology of the study we used Moral Foundations Theory describing five basic dimensions of moral domain including Harm/Care, Fair- ness/Reciprocity, Ingroup/Loyalty, Authority/Respect, and Purity/Sanctity. The sample comprised 446 Mon- golian, 450 Russian and 117 German adolescents at the age of 12…16 years old. We used three versions of Moral Foundations Questionnaire in different languages. The results of statistical analysis showed that general analy- sis, based on relations between scales, was acceptable. The replication of factor structure was low. It was revealed that Mongolian adolescents had most conservative moral foundations. Moral foundations of Russian adolescents from Altai Republic were quite close to Mongolian ones, while German adolescents showed much more «progressive» moral foundations which were typical for western societies.

Orthopaedic research and education foundation and industry.

Science.gov (United States)

Wurth, Gene R; Sherr, Judy H; Coffman, Thomas M

2003-07-01

Members of orthopaedic industry commit a significant amount of funds each year to support research and education programs that are directly related to their product(s). In addition, industry supports organizations such as the Orthopaedic Research and Education Foundation. The relationship between the Orthopaedic Research and Education Foundation and industry began in the early 1980s. The support to the Orthopaedic Research and Education Foundation from industry primarily has come in the form of unrestricted grants. These grants best can be looked at as an investment rather than a contribution. This form of giving, once called corporate philanthropy is more accurately referred to as strategic philanthropy. Members of industry make these investments to enhance their reputations, build brand awareness, market their products and services, improve employee morale, increase customer loyalty, and establish strategic alliances. The specialty of orthopaedics is among the leaders in medicine in the amount of funding raised within the specialty for research and education programs. This is because of the amount of support from members of industry and the surgeons. During the past 15 years, 40% of the annual support to the Orthopaedic Research and Education Foundation has come from industry and the balance has come from surgeons and members of lay public. Future industry support of the Orthopaedic Research and Education Foundation and other organizations within the specialty of orthopaedics will be dependent on the continued demonstration of tangible returns in areas described.

The foundations and the benefactors of Nowodworski Schools in Krakow

Directory of Open Access Journals (Sweden)

Tomasz Graff

2013-12-01

Full Text Available Nowodworski Schools, whose current institutionalized continuator is Bartłomiej Nowodworski High School, have a legacy of a long history. The idea to found private schools was initially brought forward by the authorities and professors of the Cracovian University in 1586. The project was finally launched in 1588 mainly due to energetic steps taken by the subsequent chancellor of the Cracovian University doctor of medicine – Stanisław Pik Zawadzki. Over the first decades of its existence the schools faced numerous hardship. The institution was underfunded and both professors and students were exposed to epidemics so frequent in those times, such as for instance the plague in September 1588. Some conservative professors of the University also called for closing the academic colonies. Despite all the predicaments, the institution managed to survive. The most important benefactor for private schools in those difficult years was a Cracovian bishop Piotr Tylicki (in office: 1607–1616, who with the consent of the local chapter, donated PLN 10 000 to fund a separate professor department where the professors were obliged to give a one hour daily lecture in The Upper College as well as 2 hour classes in pronunciation and stylistic in private schools. The situation, however, did not improved significantly. In those times of crisis of private schooling there appeared the foundations of the Knight of the Maltese Order – Barłomiej Nowodworski. Nowodworski was a benefactor for numerous institutions, however, his most famous charity was his foundations for Nowodworski Schools. He donated PLN 8000 in 1612, 1617 and PLN 7000 in 1619 making it possible for those private schools to survive the difficult times. Nowodworski Schools had many benefactors, however, besides the foundation of B. Nowodworski the most prominent benefactors were Gabriel Prewancjusz Władysławski. He donated PLN 50 000. Thanks to his efforts and with the contribution from the King

Technology-Enhanced Learning (TEL) can be used to educate Foundation Programme trainee (F1 and F2) doctors. Despite the advantages of TEL, learning behaviours may be exhibited that are not desired by system developers or educators. The aim of this evaluation was to investigate how learner behaviours (e.g. time spent on task) were affected by temporal (e.g. time of year), module (e.g. word count), and individual (e.g. knowledge) factors for 16 mandatory TEL modules related to prescribing and therapeutics. Data were extracted from the SCRIPT e-Learning platform for first year Foundation trainee (F1) doctors in the Health Education England's West Midland region from 1(st) August 2013 to 5(th) August 2014. Generalised Estimating Equation models were used to examine the relationship between time taken to complete modules, date modules were completed, pre- and post-test scores, and module factors. Over the time period examined, 688 F1 doctors interacted with the 16 compulsory modules 10,255 times. The geometric mean time taken to complete a module was 28.9 min (95% Confidence Interval: 28.4-29.5) and 1,075 (10.5%) modules were completed in less than 10 min. In February and June (prior to F1 progression reviews) peaks occurred in the number of modules completed and troughs in the time taken. Most modules were completed, and the greatest amount of time was spent on the learning on a Sunday. More time was taken by those doctors with greater pre-test scores and those with larger improvements in test scores. Foundation trainees are exhibiting unintended learning behaviours in this TEL environment, which may be attributed to several factors. These findings can help guide future developments of this TEL programme and the integration of other TEL programmes into curricula by raising awareness of potential behavioural issues that may arise.

Frazier Hall: The foundation failure that didn't

International Nuclear Information System (INIS)

Robinson, L.

1994-01-01

Frazier Hall is the oldest building on the Idaho State University campus--built before scientific foundation design was common. Its footings were clearly under designed, compared with modern practice. In fact, conventional analysis of the bearing capacity of two footings of this historic building indicate a failure condition. However, this structure is 60 years old and the foundation is still functioning. Possible reasons for the discrepancy between the analysis results and reality are posed and evaluated. This exercise gives some valuable insights into the process of foundation analysis and design. 7 refs., 5 figs

Basements in climates 6 and 7 can account for a fraction of a home's total heat loss when fully conditioned. Such foundations are a source of moisture, with convection in open block cavities redistributing water from the wall base, usually when heating. Even when block cavities are capped, the cold foundation concrete can act as a moisture source for wood rim joist components that are in contact with it. Because below-grade basements are increasingly used for habitable space, cold foundation walls pose challenges for moisture contribution, energy use, and occupant comfort.

A coupled FE and scaled boundary FE-approach for the earthquake response analysis of arch dam-reservoir-foundation system

International Nuclear Information System (INIS)

Wang Yi; Lin Gao; Hu Zhiqiang

2010-01-01

For efficient and accurate modelling of arch dam-reservoir-foundation system a coupled Finite Element method (FEM) and Scaled Boundary Finite Element method (SBFEM) is developed. Both the dam-foundation interaction and the dam-reservoir interaction including the effect of reservoir boundary absorption are taken into account. The arch dam is modelled by FEM, while the reservoir domain and the unbounded foundation are modelled by SBFEM. In order to make comparison with the results available in the literature, the Morrow Point arch dam is selected for numerical analysis. The analyses are carried out in the frequency domain, and then the time-domain response of the dam-reservoir-foundation system is obtained by Inverse Fourier Transform.

Shifting liberal and conservative attitudes using moral foundations theory.

Science.gov (United States)

Day, Martin V; Fiske, Susan T; Downing, Emily L; Trail, Thomas E

2014-12-01

People's social and political opinions are grounded in their moral concerns about right and wrong. We examine whether five moral foundations--harm, fairness, ingroup, authority, and purity--can influence political attitudes of liberals and conservatives across a variety of issues. Framing issues using moral foundations may change political attitudes in at least two possible ways: (a) Entrenching: Relevant moral foundations will strengthen existing political attitudes when framing pro-attitudinal issues (e.g., conservatives exposed to a free-market economic stance) and (b) Persuasion: Mere presence of relevant moral foundations may also alter political attitudes in counter-attitudinal directions (e.g., conservatives exposed to an economic regulation stance). Studies 1 and 2 support the entrenching hypothesis. Relevant moral foundation-based frames bolstered political attitudes for conservatives (Study 1) and liberals (Study 2). Only Study 2 partially supports the persuasion hypothesis. Conservative-relevant moral frames of liberal issues increased conservatives' liberal attitudes. © 2014 by the Society for Personality and Social Psychology, Inc.

2017-08-23

In this systematic literature review, all the Shiite-Islamic documents (Quran and Hadith) without any time limitation were surveyed, analyzed and synthesized for the purpose of determining the foundations of lifelong health. The data were analyzed and combined using inductive qualitative content analysis method. Two main categories were emerged from the analysis: "prevention of health problems" and "health maintenance and promotion." In conclusion based on Islamic perspective, the foundations of comprehensive health of a person, i.e., health in all physical, mental, social, and spiritual dimensions, are begun to form at four stages: the time of marriage of his parents, the moment of their conception, when he is unborn in his mother womb, and during infancy period. Observing religion instructions in this regard is not the sufficient condition for being completely healthy; however, such instructions can provide a base for being a healthy person.

2012-12-01

Full Text Available The research reported in this article attempts to discover who holds the power in open source software foundations through the analysis of governance documents. Artificial neural network analysis is used to analyse the content of the bylaws of six open source foundations (Apache, Eclipse, GNOME, Plone, Python, and SPI for the purpose of identifying power structures. Results of the research suggest that: i the actions of an open source software foundation are centered around one of three groups: Members, Chairman/President/Executive Director, and Board of Directors; ii in only one of the six foundations is the Board of Directors responsible for both the community and the product; and iii artificial neural network analysis of the content of bylaws provides unbiased insights of the power structure of open source software foundations. These results may prove useful to those who contribute to open source foundations and use their products and services.

The instrumentation and control system for the research reactor in Research Reactor Institute, Kyoto University has been used for the safe and steady operation since the initial critical attainment in 1964. It has been modified and added many devices in the chance of increasing the reactor power from 1 MW to 5 MW, installing new experimental facilities or fitting to modified nuclear regulations. In order to avoid the unscheduled shutdown of the research reactor by cause the failure of the devices, most of instrumentation system was renewed in 1999. Operating the research reactor more safely and reliably, Supervisory Control Automation and Data Acquisition System which employed personal computers with the Windows NT operating system was added to the conventional instrumentation system, and the fieldbus system called Foundation Fieldbus was installed. Compared with conventional instrumentation system, each fieldbus system has some advantages. Many kinds of fieldbus systems have been developed and sold on the markets in some countries. Foundation Fieldbus standardizing international, which was able to use the devices made by multi-vendor was tentatively installed to study particular techniques about Foundation Fieldbus. The primary coolant flow rate, the temperature difference between the reactor tank inlet and outlet temperatures, the calorimetric power and the reactor power in nuclear instrumentation are monitored on human-machine interface devices on the fieldbus. The programmable logic controller is employed to control the information system for the reactor. This paper introduces Foundation Fieldbus installed. (author)

Mathematical foundation of quantum annealing

International Nuclear Information System (INIS)

Morita, Satoshi; Nishimori, Hidetoshi

2008-01-01

Quantum annealing is a generic name of quantum algorithms that use quantum-mechanical fluctuations to search for the solution of an optimization problem. It shares the basic idea with quantum adiabatic evolution studied actively in quantum computation. The present paper reviews the mathematical and theoretical foundations of quantum annealing. In particular, theorems are presented for convergence conditions of quantum annealing to the target optimal state after an infinite-time evolution following the Schroedinger or stochastic (Monte Carlo) dynamics. It is proved that the same asymptotic behavior of the control parameter guarantees convergence for both the Schroedinger dynamics and the stochastic dynamics in spite of the essential difference of these two types of dynamics. Also described are the prescriptions to reduce errors in the final approximate solution obtained after a long but finite dynamical evolution of quantum annealing. It is shown there that we can reduce errors significantly by an ingenious choice of annealing schedule (time dependence of the control parameter) without compromising computational complexity qualitatively. A review is given on the derivation of the convergence condition for classical simulated annealing from the view point of quantum adiabaticity using a classical-quantum mapping

Activating analytic thinking enhances the value given to individualizing moral foundations.

Science.gov (United States)

Yilmaz, Onurcan; Saribay, S Adil

2017-08-01

Two central debates within Moral Foundations Theory concern (1) which moral foundations are core and (2) how conflict between ideological camps stemming from valuing different moral foundations can be resolved. Previous studies have attempted to answer the first question by imposing cognitive load on participants to direct them toward intuitive and automatic thought. However, this method has limitations and has produced mixed findings. In the present research, in two experiments, instead of directing participants toward intuitive thought, we tested the effects of activating high-effort, analytic thought on participants' moral foundations. In both experiments, analytic thought activation caused participants to value individualizing foundations greater than the control condition. This effect was not qualified by participants' political orientation. No effect was observed on binding foundations. The results are consistent with the idea that upholding individualizing foundations requires mental effort and may provide the basis for reconciliation between different ideological camps.

2015-09-01

Full Text Available The paper focuses on the material mechanics properties of reinforced concrete and steel casing composite concrete under pseudo-static loads and their application in structure. Although elevated pile-group foundation is widely used in bridge, port and ocean engineering, the seismic performance of this type of foundation still need further study. Four scale-specimens of the elevated pile-group foundation were manufactured by these two kinds of concrete and seismic performance characteristic of each specimen were compared. Meanwhile, the special soil box was designed and built to consider soil-pile-superstructure interaction. According to the test result, the peak strength of strengthening specimens is about 1.77 times of the others and the ultimate displacement is 1.66 times of the RC specimens. Additionally, the dissipated hysteric energy capability of strengthening specimens is more than 2.15 times of the others as the equivalent viscous damping ratio is reduced by 50%. The pinching effect of first two specimens is more obvious than latter two specimens and the hysteretic loops of reinforced specimens are more plumpness. The pseudo-static tests also provided the data to quantitatively assessment the positive effect of steel casing composite concrete in aseismatic design of bridge.

Excavationless Exterior Foundation Insulation Field Study

Energy Technology Data Exchange (ETDEWEB)

Schirber, T.; Mosiman, G.; Ojczyk, C.

2014-10-01

Building science research supports installing exterior (soil side) foundation insulation as the optimal method to enhance the hygrothermal performance of new homes. With exterior foundation insulation, water management strategies are maximized while insulating the basement space and ensuring a more even temperature at the foundation wall. However, such an approach can be very costly and disruptive when applied to an existing home, requiring deep excavation around the entire house. The NorthernSTAR Building America Partnership team implemented an innovative, minimally invasive foundation insulation upgrade technique on an existing home. The approach consisted of using hydrovac excavation technology combined with a liquid insulating foam. The team was able to excavate a continuous 4" wide by 4' to 5' deep trench around the entire house, 128 linear feet, except for one small part under the stoop that was obstructed with concrete debris. The combination pressure washer and vacuum extraction technology also enabled the elimination of large trenches and soil stockpiles normally produced by backhoe excavation. The resulting trench was filled with liquid insulating foam, which also served as a water-control layer of the assembly. The insulation was brought above grade using a liquid foam/rigid foam hybrid system and terminated at the top of the rim joist. Cost savings over the traditional excavation process ranged from 23% to 50%. The excavationless process could result in even greater savings since replacement of building structures, exterior features, utility meters, and landscaping would be minimal or non-existent in an excavationless process.

Lewis Swift celebrated comet hunter and the people's astronomer

CERN Document Server

Kronk, Gary W

2017-01-01

This biography covers the life of Lewis Swift (1820-1913), who discovered 13 comets and nearly 1,200 other deep sky objects. All 13 comets found by Swift now bear his name, including three periodic comets with periods of 6 years (11P/Tempel-Swift-LINEAR), 9 years (64P/Swift-Gehrels), and 133 years (109P/Swift-Tuttle). Swift's enthusiasm and success as an amateur astronomer helped make him famous in the United States. With the help of others, Swift was able to buy a 16-inch refractor, the third largest telescope in the United States at the time. Hulbert Harrington Warner built "Warner Observatory" to house this telescope. As a prolific writer and lecturer, Swift's stories appeared in newspapers and magazines, while his lectures showed that he was able to explain anything in a way that everyone could understand.  When Warner went broke during the "Panic of 1893," Swift was forced to leave his home. Almost two dozen invitations arrived from around the United States asking him to bring his telescope to their ci...

Influence of foundation layering on soil-structure system motion

International Nuclear Information System (INIS)

Philippacopoulos, A.J.

1985-01-01

This paper is concerned with effects on structural motion due to layering of the foundation. Impedance functions for foundations which consist of a layer resting on a viscoelastic half-space are used on a simple 3-dof SSI system and transfer functions are generated. It is shown that the layering of the foundation effects the motion of the SSI system. These effects are more pronounced for shallow layers with large difference in shear wave velocity from the underlying half-space. (orig.)

Applications of the observational method in deep foundations

Directory of Open Access Journals (Sweden)

Fathi M. Abdrabbo

2012-12-01

Full Text Available The observational method was introduced into geotechnical engineering to improve both theories and construction techniques. This method was developed to avoid highly conservative assumptions about soil properties in geotechnical design when faced with unavoidable uncertainties of natural ground conditions. The assumptions involved in soil mechanics theories usually differ to a certain extent from reality. These assumptions can be improved by employing an observational database. Thus, theories of geotechnical engineering can be developed by observations during the construction stage. Moreover, precise management of construction work by close observations is essential to avoid risk and to alter the design if needed to match the real conditions. This paper sheds some light on the importance of the observational concept in deep foundations through three case studies. The first one demonstrates the effect of working hypotheses on design outputs of an open caisson of 22 m internal diameter. The other two case studies present the difference between theory and reality during construction stage of auger cast-in-place piles (ACIP in difficult subsoil conditions. Importance of merging the documented theories with the available observations is discussed. The study shows that working hypotheses and engineering models affect the cost and the time required for construction of deep foundations. Field observations are essential during installation of ACIP at a site. Some precautions should be considered when drilling ACIP through sandstone of inclined top surface. These precautions are mainly dependent upon field observations during construction. ACIP can be used effectively in soil formations that have galleries and caves using a cement–bentonite mixture to fill the holes of the unsuccessful piles. Finally, the paper shares a series of practical guidelines with engineering community all over the world that may assist in design and construction of deep

Mono pile foundation. Final report

Energy Technology Data Exchange (ETDEWEB)

Lyngesen, S.; Brendstrup, C.

1997-02-01

The use of mono piles as foundations for maritime structures has been developed during the last decades. The installation requirements within the offshore sector have resulted in equipment enabling driving of piles up to 3-4 m to large penetration depths. The availability of this equipment has made the use of large mono piles feasible as foundations for structures like wind turbines. The mono pile foundations consists of three parts; the bare pile, a conical transition and a boat landing. All parts are prefitted at the yard in order to minimise the installation work that has to be carried out offshore. The study of a mono pile foundations for a 1.5 MW wind turbine has been conducted for two locations, Horns Rev and Roedsand. Three different water depths: 5, 8 and 11 m have been investigated in the study. The on-site welding between pile and conical transition is performed by an automatic welding machine. Final testing and eventually repair of the weld are conducted at least 16 hours after welding. This is followed by final installation of J-tube, tie-in to subsea cables and installation of the impressed current system for corrosive protection of the mono pile. The total cost for procurement and installation of the mono pile using the welded connection is estimated. The price does not include procurement and installation of access platform and boat landing. These costs are estimated to 250.000 DKK. Depending on water depth the cost of the pile ranges from 2,2 to 2,7 million DKK. Procurement and fabrication of the pile are approx. 75% of the total costs. The remaining 25% are due to installation. The total costs are very sensitive to the unit price of pile steel. During the project it became obvious that ice load has a very large influence on the dimensions of the mono pile. (EG)

Special Relativity And Its Experimental Foundation

Yuan Zhong Zhang

1997-01-01

This book is divided into two parts. In the first part we introduce the foundations of special relativity, such as, the inertial frame of reference, the definition of simultaneity, and Einstein's two basic hypotheses. We give the main relativistic effects, e.g. the relativity of simultaneity,velocity addition, length-contraction, the apparent shape of a moving body, time-dilation,Doppler effect, and the Thomas precession, In particular, the simultaneity problem and slow transport of clocks are investigated in detail by means of the test theories of special relativity.In the second part, variant types of experiments performed up to now are analyzed and compared to the predictions of special relativity. This shows that the experiments are a test of the two-way speed of light, but not of the one-way speed of light

Study on monitoring of deep foundation pit with SMW engineering method plus anchor cable retaining structure

Science.gov (United States)

Chen, Wenzhao; Cui, Wenping

2018-03-01

The SMW method has many advantages, such as little influence on the surrounding environment, good watertight performance, wide range of application, short construction period, low cost and so on. In this paper, we chose the SMW engineering method combined with anchor cable to support structure in the second phase deep foundation pit of Jinan LuJinDongCheng as the research object, monitored and analysed the horizontal displacement of the pile top, Peripheral surface subsidence and internal force of the anchor cable in the foundation pit. We also discussed the displacement, internal force of anchor cable and the settlement of surrounding environment in the excavation of foundation pit and in different stages of construction. Conclusion:(1)The maximum horizontal displacement of the retaining structure is closely related to the depth and time of excavation, the construction of anchor cable can well limit the deformation of pile body; (2)Groundwater seepage caused by foundation pit dewatering will change the effective stress of soil. The change of groundwater level has an important influence on the working behavior of smw anchor cable supporting structure.

Numerical simulation of installation of skirt foundations

Energy Technology Data Exchange (ETDEWEB)

Vangelsten, Bjoern Vidar

1997-12-31

Skirt foundation has been increasingly used for permanent offshore oil installations and anchors for drilling ships. Suction is commonly used in skirt foundation installing. If a large amount of suction is applied, the soil around the foundation may fail and the foundation become useless. This thesis studies failure due to high seepage gradients, aiming to provide a basis for reducing the risk of such failures. Skirt penetration model testing has shown that to solve the problem one must understand what is going on at the skirt tip during suction installation. A numerical model based on micro mechanics was developed as continuum hypothesis was seen to be unsuitable to describe the processes in the critical phases of the failure. The numerical model combines two-dimensional elliptical particles with the finite difference method for flow to model water flow in a granular material. The key idea is to formulate the permeability as a function of the porosity of the grain assembly and so obtain an interaction between the finite difference method on flow and the particle movement. A computer program, DYNELL, was developed and used to simulate: (1) weight penetration of a skirt wall, (2) combined suction and weight penetration of a skirt wall, and (3) critical gradient tests around a skirt wall to study failure mechanisms. The model calculations agree well with laboratory experiments. 16 refs., 124 figs., 21 tabs.

Analysis of Foundation of Tall R/C Chimney Incorporating Flexibility of Soil

Science.gov (United States)

Jayalekshmi, B. R.; Jisha, S. V.; Shivashankar, R.

2017-09-01

Three dimensional Finite Element (FE) analysis was carried out for 100 and 400 m high R/C chimneys having piled annular raft and annular raft foundations considering the flexibility of soil subjected to across-wind load. Stiffness of supporting soil and foundation were varied to evaluate the significance of Soil-Structure Interaction (SSI). The integrated chimney-foundation-soil system was analysed by finite element software ANSYS based on direct method of SSI assuming linear elastic material behaviour. FE analyses were carried out for two cases of SSI namely, (1) chimney with annular raft foundation and (2) chimney with piled annular raft foundation. The responses in raft such as bending moments and settlements were evaluated for both the cases and compared to those obtained from the conventional method of analysis of annular raft foundation. It is found that the responses in raft vary considerably depending on the stiffness of the underlying soil and the stiffness of foundation. Piled raft foundations are better suited for tall chimneys to be constructed in loose or medium sand.

Numerical Modelling of Connections Between Stones in Foundations of Historical Buildings

Przewlocki, Jaroslaw; Zielinska, Monika; Grebowski, Karol

2017-12-01

The aim of this paper is to analyse the behaviour of old building foundations composed of stones (the main load-bearing elements) and mortar, based on numerical analysis. Some basic aspects of historical foundations are briefly discussed, with an emphasis on their development, techniques, and material. The behaviour of a foundation subjected to the loads transmitted from the upper parts of the structure is described using the finite element method (FEM). The main problems in analysing the foundations of historical buildings are determining the characteristics of the materials and the degree of degradation of the mortar, which is the weakest part of the foundation. Mortar is graded using the damaged-plastic model. In this model, exceeding the bearing capacity occurs due to the degradation of materials. The damaged-plastic model is the most accurate model describing the work and properties of mortar because it shows exactly what happens with this material throughout its total load history. For a uniformly loaded fragment of the foundation, both stresses and strains were analysed. The results of the analysis presented in this paper contribute to further research in the field of understanding both behaviour and modelling in historical buildings’ foundations.

1984-01-01

At the Leningrad NPP during the seren-year period four K-50a-65/3000 turbine and their foundation deformation measurements have been performed by means of a high accuracy geometric levelling. Determined are: settling values and values of residual deformations of the lower foundation plate, thermal deformations of the upper foundation structure under different turbine operation conditions, turbine shafting bearing shafting at the horizontal joint level; horizontal time required for shafting bearing stabilization upon shut-down and start-up of the turbine. Tne turbine foundation columns elongation has been determined with accuracy of 0.05-0.06 mm and 0.06-0.08 mm at the shut-down or operating turbine, respectively. For levelling a leveller has been applied, the accuracy of measurement of relative height of which is equal to 0.03 mm at the 6 m collimating ray length. The measurement accuracy is decreasing at the operating turbine up to 0.04-0.05 mm. As a result of measurements it has been revealed that relative bearing shifting occurs during the first 8-10 days after shut-down and 4-5 days after start-up and reach 2.5 and 2.0 mm, respectively. In addition, shafting bearing centers shifting has been determined at the operating and shut-down turbine. The conclusion is drawn that the number of problems of shafting bearing alignment of high power turbines arising during their mounting, operation and maintenance, one may succeed in solving by means of high accuracy geometric levelling

Peace Education: Exploring Some Philosophical Foundations

Science.gov (United States)

Page, James S.

2004-01-01

Peace education has been recognized as an important aspect of social education for the past three decades. The critical literature as well as official documents, however, have given little attention to its philosophical foundations. This essay explores these foundations in the ethics of (1) virtue, (2) consequentialism, (3) aesthetics, (4) conservative politics and (5) care. Each of these alone composes a significant element of peace education, although ultimately its solid basis can only be established through an integrative approach encouraging a culture of peace. The more complete development and articulation of the philosophical rationale of peace education is yet to be accomplished and remains a task for the future.

Manap, N.; Tan, K. Y.; Syahrom, N.

2017-12-01

Pile foundation is widely used in construction and building marine structures. This is because pile foundation is an important structure and should have long-term durability. However, in waterfront development, a lot of issues from the seawater should be considered distinctively because it consists of many problems that can affect the building structure especially the foundation of the building. Thus, a research should be conducted to identify issues of pile foundation at waterfront development and determine its prevention methods. The research was carried out through interviews with the developers and contractors from the projects of Lexis Hibiscus at Port Dickson, Negeri Sembilan and Redevelopment for Deep-Water Facilities at Quay 6 in Pasir Gudang, Johor, Malaysia. The objectives of this research are to identify issues of pile foundation and to determine the prevention methods of pile foundation issues at waterfront development. All respondents agreed that the main issues of pile foundations at waterfront development are the wave and tide condition. The prevention methods of the issue faced at waterfront development that are most frequently used for the pile foundation are coating system and concrete cover. This research is beneficial to all developers and contractors to ensure pile foundations at waterfront development can be protected by using the prevention methods.

The large-sized, high performance vibrating table in the Nuclear Power Engineering Test Center is installed on a large-scale concrete foundation of length 90.9 m, width 44.8 m and maximum thickness 21 m, weighing 150,000 tons. Through the experimental study on the behavior of the foundation, which is set on gravel ground, useful information should be obtained on the siting of a nuclear power plant on the Quaternary stratum ground. The objective of research is to grasp the vibration characteristics of the foundation during the vibration of the table to evaluate the interaction between the foundation and the ground, and to evaluate an analytical method for numerically simulating the vibration behavior. In the present study, the vibration behavior of the foundation was clarified by measurement, and in order to predict the vibration behavior, the semi-infinite theory of elasticity was applied. The accuracy of this analytical method was demonstrated by comparison with the measured results. (Mori, K.)

Science.gov (United States)

Gordon, Amanda; Coulson, Sally

2004-11-01

Cosmetic foundation products are easily transferred to clothing and other surfaces as a result of contact with such objects. Examination of past cases involving cosmetics in New Zealand has shown cosmetic foundation to be one of the more common cosmetic products encountered. The aim of this research was to determine the most discriminating method for the comparison of transferred foundation with samples obtained from a known source in forensic casework. Fifty-three foundation samples were analyzed by Fourier transform infrared spectroscopy (FTIR), gas chromatography with a flame ionization detector (GC-FID) and scanning electron microscopy-energy dispersive X-Ray analysis (SEM-EDX). It was found that a 5 mm2 section of a light smearing was enough to provide detectable results. The discriminating powers for FTIR, SEM-EDX and GC-FID were 98.3, 93.8, and 82.0% respectively. A combination of all three techniques provided a discriminating power of 99.7%, meaning that almost complete discrimination was achieved between the foundation samples.

Children and war: the work of the Children and War Foundation

Directory of Open Access Journals (Sweden)

William Yule

2013-01-01

Full Text Available The Children and War Foundation was established after the authors’ experiences following the civil war in former Yugoslavia in the mid-1990s. Many organizations tried to mitigate the effects of the war on children but few interventions were based on evidence and fewer were properly evaluated. The Foundation was established in Norway with the aim of promoting better evidence-based interventions to help children after wars and natural disasters.The Foundation has developed a number of empirically grounded manuals that aim to help children learn strategies that will lessen the stress reactions that they have developed. The manuals are designed to be delivered by personnel who are not necessarily very experienced in child mental health. They are aimed at groups of children using a public health approach to reach large numbers in a short space of time. The strategies are not intended as individual therapy.The Teaching Recovery Techniques manual has been used following a number of earthquakes and other natural disasters and data from a number of these will be discussed. A Writing for Recovery manual is aimed at helping adolescents and is based on the seminal work of James Pennebaker. It is currently being evaluated in three separate studies. A group-based manual to help children bereaved by war or disaster has recently been developed.

Al- Khwarizmi and axiomatic foundation of algebra

International Nuclear Information System (INIS)

Fares, N.

2015-01-01

This paper intends to investigate the axiomatic foundations of algebra, as they were presented in the book of algebra of al-Khwarizmi (9 th century), and as they were developed in many subsequent Arabic works. The paper gives also a description of algebra evolution towards a discipline independent ofgeometry and arithmetic: the two disciplines whosemarriage had led to its birth.By an in depth reading of some details in the text of al Khwarizmi , we concluded that this mathematician intended to lay down the axiomatic foundations of that new discipline. His resort to arithmetical and geometrical means was a way of making his theory more accessible. He used them to justify the axioms: those that were not explicitly introduced per se, and those that were remained implicit. The paper also relies on some unedited writingsof al-Khwarizmi's successors, which could shedlight on the ways they used to consolidate the foundations of algebra and improve its methods. (author)

Taxation of Foreign Foundations in Light of EU Law

DEFF Research Database (Denmark)

Werlauff, Erik

2016-01-01

a) The article analyses why it is necessary to consider European law when national tax law is to test whether a foundation (i.e., an independent institution) domiciled in another EU/EEA country can be considered as an independent tax subject. In Denmark the qualification for tax purposes...... of a foreign foundation has so far been decided on the basis purely of national tax law. The article argues that it is necessary to consider European law in the testing because it creates a restriction on the freedom of establishment and capital movement if the foundation is not approved as the ‘beneficial...... owner’ of the income received by the foundation. Such restriction must be able to be justified on the grounds of compelling reasons, suitability and proportionality. b) There has been a long-standing tradition in Denmark and undoubtedly also in many other member states, for tax law to be sceptic...

Linear Programming: Foundations and Extensions is an introduction to the field of optimization. The book emphasizes constrained optimization, beginning with a substantial treatment of linear programming, and proceeding to convex analysis, network flows, integer programming, quadratic programming, and convex optimization. The book is carefully written. Specific examples and concrete algorithms precede more abstract topics. Topics are clearly developed with a large number of numerical examples worked out in detail. Moreover, Linear Programming: Foundations and Extensions underscores the purpose of optimization: to solve practical problems on a computer. Accordingly, the book is coordinated with free efficient C programs that implement the major algorithms studied: -The two-phase simplex method; -The primal-dual simplex method; -The path-following interior-point method; -The homogeneous self-dual methods. In addition, there are online JAVA applets that illustrate various pivot rules and variants of the simplex m...

[Hospitals and other philanthropic foundations in early Byzantine period].

Science.gov (United States)

Yildirim, R Vedat; Ataç, Adnan

Early Byzantine Period includes between A.D. 330 when Constantinople was established and A.D. 518 when Justinus I became emperor. In this time period, a lot of philanthropic foundations such as hospitals, hospices, orphanages, rest homes and soup kitchens are established. Many of patriarchs and religious men opened them. In some of them, it refers to there was patients' care. The oldest hospital in Constantinople was established by Hasios Marcianos, and was next to Saint Irene Church. In addition to this Empress Flacilla wife of Theodosius the Great made hospitals restored and visited patients regularly. Hospitals were not limited in the center of Empire. Hospitals and other philanthropic foundations were established in Antiochia, Alexandria, Nikea, Adrianopolis, Castoria and Jerusalem. The concept of the modern hospital (the actual care, 'hospitality' and treatment of visitors) for the civilian masses in Europe didn't come to fruition until post Constantine and the rise of Christianity. While these early Christian hospitals were grossly over their heads regarding medical capability (they essentially served as last stops for the dying or quarantine centers), the concept of providing care to the public was the actual intent. In this regard, the first civilian hospitals were developed.

Grieveson, B; Kirton, J A; Palmer, N O A; Balmer, M C

2011-08-26

The aims of this survey were to evaluate the effectiveness of workplace based assessments (WPAs) in dental foundation training (formerly vocational training [VT]). Two online questionnaire surveys were sent to 53 foundation dental practitioners (FDPs) and their 51 trainers in the Mersey Deanery at month four and month nine of the one year of dental foundation training. The questionnaires investigated the effectiveness of and trainers' and trainees' satisfaction with the WPAs used in foundation training, namely dental evaluation of performance (D-EPs), case-based discussions (DcBD) and patients' assessment questionnaires (PAQs). The questionnaires also investigated the perceived impact of reflection and feedback associated with WPAs on clinical practise and improving patient care. A total of 41 (7.4%) FDPs and 44 (86.3%) trainers responded. Of the 41 FDPs, the majority found that feedback from WPAs had a positive effect on their training, giving them insight into their development needs. Overall 84.1% of the FDPs felt the WPAs helped them improve patient care and 82.5% of trainers agreed with that outcome. The findings from this study demonstrate the value of WPAs in dental foundation training by the use of feedback and reflection in directing the learning of foundation dental practitioners and that this can lead to improved clinical practise and patient care.

Evaluation of Thermal and Thermo-mechanical Behavior of Full-scale Energy Foundations

Science.gov (United States)

Murphy, Kyle D.

This study focuses on the thermo-mechanical and thermal behavior of full-scale energy foundations installed as part of two buildings recently constructed in Colorado. The soil stratigraphy at each of the sites differed, but both foundations were expected to function as primarily end-bearing elements with a tip socketed into rock. The heat exchanger configurations were also different amongst the foundations at both sites, permitting evaluation of the role of heat exchange. A common thread for both energy foundation case histories was the monitoring of the temperature and axial strain within the foundations during heat exchange operations. The first case study involves an evaluation of the long-term thermo-mechanical response of two full-scale energy foundations installed at the new Denver Housing Authority (DHA) Senior Living Facility at 1099 Osage St. in Denver, Colorado. Due to the construction schedule for this project, the thermal properties of the foundations and surrounding subsurface could not be assessed using thermal response tests. However, instrumentation was incorporated into the foundations to assess their long-term heat exchange response as well as the thermo-mechanical strains, stresses, and displacements that occurred during construction and operation of the ground-source heat pump system. The temperature changes within the foundations during heating and cooling operations over a period of approximately 600 days ranged from 9 to 32 °C, respectively. The thermal axial stresses in the foundations were calculated from the measured strains, and ranged from 3.1 MPa during heating to --1.0 MPa during cooling. These values are within reasonable limits for reinforced concrete structures. The maximum thermal axial stress was observed near the toe of both foundations, which is consistent with trends expected for end-bearing toe boundary conditions. The greatest thermal axial strains were observed near the top of the foundations (upward expansion during

A GLANCE AT OFFSHORE WIND TURBINE FOUNDATION STRUCTURES

Directory of Open Access Journals (Sweden)

Jianhua Zhang

2016-06-01

Full Text Available Energy poverty and climate change are crucial issues we face in our societies. Offshore wind energy has been a reliable solution to both of these problems - solving our growing energy problems while reducing CO2 emission. Innovative foundation design is one of the setbacks faced by this industry. Designing and constructing a cost effective offshore wind farm is greatly hampered by technical and infrastructural challenges, especially in foundation structures. This paper provides a detailed overview of issues related to this problem, with the aim of eliminating the frequent misunderstandings which can arise among engineers and investors working in the offshore wind energy sector. It begins by investigating the latest data and recommendations regarding the design and deployment of various kinds of offshore wind turbine (OWT foundations. It provides a framework which enables us to study the different OWT foundations, including prototypes and their limitations. Various structural failure modes are highlighted and corrosion measures are presented. Moreover, various removal methods of support structures are put forward. Finally, this paper presents the setbacks preventing the spread of offshore wind energy and the future works for offshore wind energy applications.

Innovative Retrofit Insulation Strategies for Concrete Masonry Foundations

This study was designed to test a new approach for foundation insulation retrofits, with the goal of demonstrating improved moisture control, improved occupant comfort, and reduced heat loss. Because conducting experimental research on existing below-grade assemblies is very difficult, most of the results are based on simulations. The retrofit approach consists of filling open concrete block cores with an insulating material and adding R-10 exterior insulation that extends 1 ft below grade. The core fill is designed to improve the R-value of the foundation wall and increase the interior wall surface temperature, but more importantly to block convection currents that could otherwise increase moisture loads on the foundation wall and interior space. The exterior insulation significantly reduces heat loss through the most exposed part of the foundation and further increases the interior wall surface temperature. This improves occupant comfort and decreases the risk of condensation. Such an insulation package avoids the full-depth excavation necessary for exterior insulation retrofits, reduces costs, and eliminates the moisture and indoor air quality risks associated with interior insulation retrofits. Retrofit costs for the proposed approach were estimated at roughly half those of a full-depth exterior insulation retrofit.

studies have indicated the possibility of defining foundation response using plasticity theory. Results of multiple loading tests addressing the effect of embedment on the strain-hardening behavior of shallow bucket foundations under combined loading are reported. The kinematic mechanisms accompanying pre......-failure are presented. It is argued that the drained capacity of offshore bucket foundations and the ratio of plastic increments are largely influenced by embedment depth and the preload ratio V/Vpeak....

Cost-efficient foundation structures for large offshore wind farms

International Nuclear Information System (INIS)

Birch, C.; Gormsen, C.; Lyngesen, S.; Rasmussen, J. L.; Juhl, H.

1997-01-01

This paper presents the results of the development of a cost-efficient foundation for large (1.5 MW) offshore wind farms at water depth of 5 to 11 m. Previously, medium sized wind turbines (500 kW) in Denmark have been installed offshore at water depths of approximately 5 m on concrete gravity foundations. The installation of larger turbines at greater depth does, however, hold great promise in terms of wind environment and environmental considerations. The costs of a traditional gravity foundation at these increased water depths is expected to be prohibitive, and the aim of the project has been to reduce the foundations costs in general. This paper describes the theoretical basis for the geotechnical and structural design of three alternative concepts and presents an optimised layout of each based on a research and development project. The basis has been a wind farm consisting of 100 turbines. The R and D project has been undertaken by the consulting engineers Nellemann, Nielsen and Rauschenberger A/S (Gravity foundation), LICengineering A/S (Mono pile) and Ramboell (Tripod) in co-operation with the Danish utility engineering companies Elkraft and Elsamprojekt A/S. The project was partly financed by the participants and by the Danish Energy Agency through their 1996 Energy Research Programme (EFP-96). (au) 18 refs

Geometrically nonlinear dynamic and static analysis of shallow spherical shell resting on two-parameters elastic foundations

International Nuclear Information System (INIS)

Civalek, Ö.

2014-01-01

In the present study nonlinear static and dynamic responses of shallow spherical shells resting on Winkler–Pasternak elastic foundations are carried out. The formulation of the shells is based on the Donnell theory. The nonlinear governing equations of motion of shallow shells are discretized in space and time domains using the discrete singular convolution and the differential quadrature methods, respectively. The validity of the present method is demonstrated by comparing the present results with those available in the open literature. The effects of the Winkler and Pasternak foundation parameters on nonlinear static and dynamic response of shells are investigated. Some results are also presented for circular plate as special case. Damping effect on nonlinear dynamic response of shells is studied. It is important to state that the increase in damping parameter causes decrease in the dynamic response of the shells. It is shown that the shear parameter of the foundation has a significant influence on the dynamic and static response of the shells. Also, the response of the shell is decreased with the increasing value of the shear parameter of the foundation. Parametric studies considering different geometric variables have also been investigated. -- Highlights: • Nonlinear responses of shallow spherical shells are presented. • The effects of foundation parameters are investigated. • Damping effect on nonlinear dynamic response of shells is also studied

A geometrical foundation of a unified field theory

International Nuclear Information System (INIS)

Tauber, G.E.

1983-01-01

In a series of two little known papers Einstein and Mayer proposed a formalism by which they were able to obtain a theory of gravitation and electromagnetism similar to that of Kaluza and Klein. Instead of assuming, as these authors did, the existence of a five-dimensional continuum they assumed that at each point of space-time, regarded as a Riemannian space there exists a five-dimensional vector space. The purpose of this work is to generalize the approach of Einstein and Mayer to N dimensions and to lay the geometrical foundation of a possible unified field theory of gravitation with other fields.

Qixiang Fan

2015-04-01

Full Text Available With better understanding of the quality and physico-mechanical properties of rocks of dam foundation, and the physico-mechanical properties and structure design of arch dam in association with the foundation excavation of Xiluodu arch dam, the excavation optimization design was proposed for the foundation surface on the basis of feasibility study. Common analysis and numerical analysis results demonstrated the feasibility of using the weakly weathered rocks III1 and III2 as the foundation surface of super-high arch dam. In view of changes in the geological conditions at the dam foundation along the riverbed direction, the design of extending foundation surface excavation area and using consolidating grouting and optimizing structure of dam bottom was introduced, allowing for harmonization of the arch dam and foundation. Three-dimensional (3D geomechanics model test and finite element analysis results indicated that the dam body and foundation have good overload stability and high bearing capacity. The monitoring data showed that the behaviors of dam and foundation correspond with the designed patterns in the construction period and the initial operation period.

THE PHILOSOPHICAL FOUNDATIONS OF MODERN BIOENGINEERING

Directory of Open Access Journals (Sweden)

Ibrahim A. Shogar

2017-12-01

Full Text Available This paper investigates the philosophical foundations of modern bioengineering to articulate its ethical framework. Engineering as an ultimate mechanism to transform knowledge into practice is essential for both physical and biological sciences. It reduces data, concepts, and designs to pictorial forms. The integration of engineering with the newly emerging biosciences, has presented a unique opportunity to overcome the major challenges that face the environmental and human health. To harness potentials of bioengineering and establish a sustainable foundation for green technology, modern scientists and engineers need to be acquainted with the normative questions of science. In addition to acquiring the general principles of scientific research and identifying the intrinsic goals of the endeavour, philosophy of bioengineering exposes bioengineers to both the descriptive ‘how’ questions of the physical world as well as the normative ‘why’ questions of values. Such an interdisciplinary approach is significant, not only for inspiring to acquire the genuine knowledge of the existing world, but also to expose the bioengineers to their ethical and social responsibilities. Besides introducing the conceptual framework of bioengineering, this paper has investigated the three major philosophies that have been dominating the theoretical presuppositions of scientific research method in history. Namely, (i Systems biology approach; (ii Evolutionary biology approach; and (iii Mechanical view approach. To establish the ethical foundation of modern bioengineering, the paper, also has conducted an analytical study on various branches of the emerging discipline of bioscience. The paper has concluded that adopting the interdisciplinary approach in research and education is essential to harness potentials of bioengineering and to establish foundations of green technology. To achieve the final objectives of bioengineering, both the practical and theoretical

The Karun III is a double curved concrete arch dam located in Iran which was used to investigate earthquake motions and dam responses. This paper presented the study of the Karun III dam foundation interface. Using an array of 15 accelerometers, two major events that occurred on 2007.11.20 and 2007.11.21 were recorded during dam operation with a PGA at crest of 0.312 g and 0.109.g respectively. A finite element model of Karun III dam was performed. The response of the Karun III dam during the 2007 earthquake was investigated using the NSAD-DRI program. It was found that the motion of the dam foundation interface is non-uniform. There is a time shift and amplification at the abutment compared to those at the base of the dam. The results showed that the spatially varying earthquake assumption is in good agreement with the recorded displacement of the dam.

Dyslexia is the most common form of specific learning difficulty affecting approximately 6% of the general UK population and believed to affect approximately 2% of UK medical students. The impact of dyslexia on early practice has not been studied. To develop an understanding of the challenges faced by doctors with dyslexia in the first year of practice and their support requirements. Semistructured telephone interviews were conducted with seven foundation year 1 doctors with dyslexia from Scottish hospitals between March 2013 and August 2013. Foundation doctors indicated that due to their dyslexia, they experience difficulty with all forms of communication, time management and anxiety. There were concerns about disclosure of their dyslexia to colleagues and supervisors. Coping strategies used frequently were safety-netting and planning; technology solutions did offer some assistance. Although technological interventions have the potential to offer benefits to foundation doctors with dyslexia, increased openness about a diagnosis of dyslexia with discussion between doctor and supervisors about the challenges and anxieties is likely to provide the most benefit.

Post-Foundational Discourse Analysis: A Suggestion for a Research Program

Directory of Open Access Journals (Sweden)

Tomas Marttila

2015-08-01

Full Text Available Post-foundational discourse analysis, also labeled as Essex School in Discourse Analysis, has been observed to suffer from a considerable methodological deficit that limits its applicability in empirical research. The principal aim of this article is to overcome this methodological deficit by constructing the research program of the post-foundational discourse analysis that facilitates its operationalization in empirical research. In accordance with Imre LAKATOS (1970 and David HOWARTH (2004a, a research program is referred to an internally consistent and openly scrutinizable system of theoretical, methodological and phenomenal concepts that opens up the possibility to distinguish between the "negative" and the "positive" heuristics of empirical research. The first three sections develop the positive heuristics of the post-foundational discourse analysis by elucidating its theoretical foundations, methodological position and phenomenal framework. The concluding fourth section draws on the presented positive heuristics to outline the analytical stages and strategies of the post-foundational discourse analysis and discusses suitable methods for sampling and interpreting empirical data.

Electrodynamics and Spacetime Geometry: Foundations

Science.gov (United States)

Cabral, Francisco; Lobo, Francisco S. N.

2017-02-01

We explore the intimate connection between spacetime geometry and electrodynamics. This link is already implicit in the constitutive relations between the field strengths and excitations, which are an essential part of the axiomatic structure of electromagnetism, clearly formulated via integration theory and differential forms. We review the foundations of classical electromagnetism based on charge and magnetic flux conservation, the Lorentz force and the constitutive relations. These relations introduce the conformal part of the metric and allow the study of electrodynamics for specific spacetime geometries. At the foundational level, we discuss the possibility of generalizing the vacuum constitutive relations, by relaxing the fixed conditions of homogeneity and isotropy, and by assuming that the symmetry properties of the electro-vacuum follow the spacetime isometries. The implications of this extension are briefly discussed in the context of the intimate connection between electromagnetism and the geometry (and causal structure) of spacetime.

Foundational workplace safety and health competencies for the emerging workforce☆

Science.gov (United States)

Okun, Andrea H.; Guerin, Rebecca J.; Schulte, Paul A.

2016-01-01

Introduction Young workers (aged 15–24) suffer disproportionately from workplace injuries, with a nonfatal injury rate estimated to be two times higher than among workers age 25 or over. These workers make up approximately 9% of the U.S. workforce and studies have shown that nearly 80% of high school students work at some point during high school. Although young worker injuries are a pressing public health problem, the critical knowledge and skills needed to prepare youth for safe and healthy work are missing from most frameworks used to prepare the emerging U.S. workforce. Methods A framework of foundational workplace safety and health knowledge and skills (the NIOSH 8 Core Competencies)was developed based on the Health Belief Model (HBM). Results The proposed NIOSH Core Competencies utilize the HBM to provide a framework for foundational workplace safety and health knowledge and skills. An examination of how these competencies and the HBM apply to actions that workers take to protect themselves is provided. The social and physical environments that influence these actions are also discussed. Conclusions The NIOSH 8 Core Competencies, grounded in one of the most widely used health behavior theories, fill a critical gap in preparing the emerging U.S. workforce to be cognizant of workplace risks. Practical applications Integration of the NIOSH 8 Core Competencies into school curricula is one way to ensure that every young person has the foundational workplace safety and health knowledge and skills to participate in, and benefit from, safe and healthy work.

Learning needs in clinical biochemistry for doctors in foundation years.

Science.gov (United States)

Khromova, Victoria; Gray, Trevor A

2008-01-01

Most medical school curricula have reduced the amount of time available for teaching in pathology despite the fact that junior staff in the early stages of their training were responsible for requesting the majority of pathology tests on acutely ill hospital patients. So, the lack of specific training in this area means that test requesting may be poorly performed and the results ill understood by these staff. This paper describes a questionnaire, which was designed to assist laboratory staff providing targeted teaching in this area. Doctors in Foundation year 1 (F1) and Foundation year 2 (F2) in Sheffield teaching hospitals were given a questionnaire to ascertain how confident they were in requesting and interpreting the results of clinical biochemistry tests. The doctors were also asked about which areas of laboratory medicine they would like to be taught. Responses were received from 82 doctors, about half those in F1 and F2. The survey revealed areas where juniors are less confident in requesting tests and interpreting results. Despite lack of confidence in interpreting the result, 18% were confident about requesting tests. Doctors were also unsure of the effects of common problems like haemolysis on the interpretation of results. More than 70% of the doctors requested specific teaching in these areas. Foundation doctors have learning needs in clinical biochemistry, addressing which would assist them in patient care. While better training in medical school may help in future, there are specific needs for those on the wards now that require targeted teaching.

Technology Solutions Case Study: Innovative Retrofit Foundation Insulation Strategies, Minneapolis, Minnesota

Energy Technology Data Exchange (ETDEWEB)

None

2015-07-01

Basements in climates 6 & 7 can account for a fraction of a home's total heat loss when fully conditioned. These foundations are a source of moisture, with convection in open block cavities redistributing water from the wall base, usually when heating. Even when block cavities are capped, the cold foundation concrete can act as a moisture source for wood rim joist components that are in contact with the wall. As below-grade basements are increasingly retrofitted for habitable space, cold foundation walls pose increased challenges for moisture durability, energy use, and occupant comfort. To address this challenge, the NorthernSTAR Building America Partnership evaluated a retrofit insulation strategy for foundations that is designed for use with open-core concrete block foundation walls. The three main goals were to improve moisture control, improve occupant comfort, and reduce heat loss.

Niederer, Peter F

2010-01-01

The aim of biomechanics is the analysis of the structure and function of humans, animals, and plants by means of the methods of mechanics. Its foundations are in particular embedded in mathematics, physics, and informatics. Due to the inherent multidisciplinary character deriving from its aim, biomechanics has numerous connections and overlapping areas with biology, biochemistry, physiology, and pathophysiology, along with clinical medicine, so its range is enormously wide. This treatise is mainly meant to serve as an introduction and overview for readers and students who intend to acquire a basic understanding of the mathematical principles and mechanics that constitute the foundation of biomechanics; accordingly, its contents are limited to basic theoretical principles of general validity and long-range significance. Selected examples are included that are representative for the problems treated in biomechanics. Although ultimate mathematical generality is not in the foreground, an attempt is made to derive the theory from basic principles. A concise and systematic formulation is thereby intended with the aim that the reader is provided with a working knowledge. It is assumed that he or she is familiar with the principles of calculus, vector analysis, and linear algebra.

Dynamic Analysis of Wind Turbine Towers on Flexible Foundations

Directory of Open Access Journals (Sweden)

S. Adhikari

2012-01-01

Full Text Available Offshore wind turbines are considered as an essential part to develop sustainable, alternative energy sources. The structures themselves are both slender and highly flexible, with a subsea foundation typically consisting of a single large diameter monopile. They are subject to intense wind and wave loadings, with the result that significant movement of both the exposed structure and the upper part of the monopile can occur. Although the structures are intended for design life of 25 to 30 years, very little is known about the long term behaviour of these structures. This paper characterizes the dynamic behaviour of these structures. A simplified approach has been proposed for the free vibration analysis of wind turbines taking the effect of foundation into account. The method is based on an Euler-Bernoulli beam-column with elastic end supports. The elastic end-supports are considered to model the flexible nature of the interaction of these systems with the foundation. A closed-form expression of the characteristic equation governing all the natural frequencies of the system has been derived. Theoretical developments are explained by practical numerical examples. Analytical as well as a new experimental approach has been proposed to determine the parameters for the foundation. Some design issues of wind turbine towers are discussed from the point of view of the foundation parameters.

In this paper, for the first time, a nonlocal Timoshenko beam model is employed for studying the wave dispersion of a fluid-conveying single-walled carbon nanotube on Viscoelastic Pasternak foundation under high and low temperature change. In addition, the phase and group velocity for the nanotube are discussed, respectively. The influences of Winkler and Pasternak modulus, homogenous temperature change, steady flow velocity and damping factor of viscoelastic foundation on wave dispersion of carbon nanotubes are investigated. It was observed that the characteristic of the wave for carbon nanotubes conveying fluid is the normal dispersion. Moreover, implying viscoelastic foundation leads to increasing the wave frequencies.

McGaghie, William C; Harris, Ilene B

2018-06-01

Simulation-based mastery learning (SBML), like all education interventions, has learning theory foundations. Recognition and comprehension of SBML learning theory foundations are essential for thoughtful education program development, research, and scholarship. We begin with a description of SBML followed by a section on the importance of learning theory foundations to shape and direct SBML education and research. We then discuss three principal learning theory conceptual frameworks that are associated with SBML-behavioral, constructivist, social cognitive-and their contributions to SBML thought and practice. We then discuss how the three learning theory frameworks converge in the course of planning, conducting, and evaluating SBML education programs in the health professions. Convergence of these learning theory frameworks is illustrated by a description of an SBML education and research program in advanced cardiac life support. We conclude with a brief coda.

Design, construction, and initial performance of wind turbine foundations in Antarctica

Energy Technology Data Exchange (ETDEWEB)

Oswell, J.M. [Naviq Consulting Inc., Calgary, AB (Canada); Mitchell, M.; Chalmers, G.; Mackinven, H. [Opus Internation Consultants Ltd., Christchurch (New Zealand)

2010-07-01

This article discussed the design and primary issues related to installing the foundations for 3 wind turbines established for generating electricity at research stations in Antarctica. The extreme frigidity of the climate, the unusual geotechnical subsoil conditions, and the technology constraints resulting from isolation had to be contended with in all aspects of the project, including site evaluation, design, construction, and monitoring. The foundation design required strict tolerance on differential settlement. The estimation of creep settlement over the entire life of the project was the most important aspect. The surface loads on the foundation were grouped by load duration to estimate the corresponding creep settlement. The tower foundations were proposed as multi-leg arrangement buried at a relatively shallow depth within the continuous permafrost. The creep behaviour of the soils, estimates of long-term settlement, and the development of contingency and mitigation measures for non-compliant foundation behaviour were necessary to meet the allowable differential settlement of the towers. The paper described the subsurface conditions, the foundation system, and the performance data taken after one thaw season.

Moral Foundations and Voting Intention in Italy

Directory of Open Access Journals (Sweden)

Patrizia Milesi

2017-11-01

Full Text Available Based on the view of morality proposed by the Moral Foundations Theory, this paper investigates whether voting intention is associated with moral foundation endorsement in not perfectly bipolar electoral contexts. Three studies carried out in Italy from 2010 to 2013, showed that controlling for ideological orientation, moral foundation endorsement is associated with voting intention. In Study 1 and 3, in fictitious and real national elections, intention to vote for right-wing political groups rather than for left-wing rivals was associated with Sanctity, confirming previous results obtained in the U.S. Furthermore, as a function of the specific competing political groups in each of the examined contexts other moral foundations predicted voting intention. In Study 1, Care and Authority predicted voting intention for the major political groups rather than for an autonomist party that aimed at decreasing central government’s fiscal power in favor of fiscal regional autonomy. In Study 3, Loyalty predicted the intention to vote for the major parliamentarian parties rather than for a movement that aimed at capturing disaffection towards traditional politics. In Study 2, at real regional elections, Loyalty predicted voting intention for the incumbent right-wing governor rather than for the challengers and Fairness predicted voting intention for left-wing extra-parliamentarian political groups rather than for the major left-wing party. Thus multiple moral concerns can be associated with voting intention. In fragmented and unstable electoral contexts, at each election the context of the competing political groups may elicit specific moral concerns that can contribute to affect voting intention beyond ideological orientation.

Huishang Tiandi deep foundation pit in Yiwu is a two-story basement,which is located in the downtown area and adjacent to the city center main traffic trunk. The surrounding environment is too com-plex to slope. The excavation depth is large, the formation is weak and complex, and the groundwater level is high.In order to ensure the safety of the foundation wall and the surrounding environment, the deformation of the foundation pit support is strictly controlled, and the deformation and internal force of the foundation supporting structure and the surrounding building are monitored.The deformation law of the foundation pit is obtained through the analysis of the horizontal displacement, the deformation rate of the supporting struc-ture, the surrounding environment of the foundation pit and the internal force of the anchor cable. The relia-bility and rationality of the design of foundation pit support are verified. It is of reference value for the de-sign and construction of other deep foundation pit engineering in Yiwu area.

Aseismic foundation system for nuclear power stations

International Nuclear Information System (INIS)

Jolivet, F.; Richli, M.

1977-01-01

The aseismic foundation system, as described in this paper, is a new development, which makes it possible to build standard nuclear power stations in areas exposed to strong earthquakes. By adopting proven engineering concepts in design and construction of components, great advantages are achieved in the following areas: safety and reliability; efficiency; design schedule; cost. The need for an aseismic foundation system will arise more and more, as a large part of nuclear power station sites are located in highly seismic zones or must meet high intensity earthquake criteria due to the lack of historic data.

Ishimaru, S.; Shimomura, Y.; Kawamuram, M.; Ikeda, Y.; Hata, I.; Miwa, S.

2005-01-01

To aim at progress of damping performance of foundations that will be built at soft ground, we have proposed an improved foundation work of backfilling a damping material into trenches dug along a foundation supported by improved soil medium. This damping material is a mixture of asphalt with crushed stones and rubber chips (MACSRC) and has itself high attenuation and mitigation performance. Not only to comprehend the attenuation ability of the improved foundation work quantitatively and qualitatively but also to verify the effectiveness of this work, we carried out forced vibration tests for two test blocks, which were constructed by a normal construction work and the above improved foundation work. According to the experiment results of the blocks by the normal construction work and by the improved foundation work that were excited by the vibration generator, magnitude of amplitudes of the latter became half than the former. Effectiveness in the attenuation performance of MACSRC was confirmed. When the block by the normal construction work was vibrated, the improved foundation work decreased magnitude of amplitude of the adjacent block than the normal construction work. It is expected that MACSRC would exert mitigation ability against earthquakes or other external and internal forces. (authors)

Full Text Available The development of maize foundation parents is an important part of genetics and breeding research, and applying new genetic information to produce foundation parents has been challenging. In this study, we focused on quantitative trait loci (QTLs and general combining ability (GCA of Ye478, a widely used foundation parent in China. We developed three sets of populations for QTL mapping and to analyze the GCA for some agronomic traits. The assessment of 15 traits resulted in the detection of 251 QTLs in six tested environments, with 119 QTLs identified through a joint analysis across all environments. Further analyses revealed that most favorable alleles for plant type-related traits were from Ye478, and more than half of the favorable alleles for yield-related traits were from R08, another foundation parent used in southwestern China, suggesting that different types of foundation parents carried different favorable alleles. We observed that the GCA for most traits (e.g., plant height and 100-kernel weight was maintained in the inbred lines descended from the foundation parents. Additionally, the continuous improvement in the GCA of the descendants of the foundation parents was consistent with the main trend in maize breeding programs. We identified three significant genomic regions that were highly conserved in three Ye478 descendants, including the stable QTL for plant height. The GCA for the traits in the F7 generation revealed that the QTLs for the given traits per se were affected by additive effects in the same way in different populations.

2013-12-01

Time-oriented data play an essential role in many Visual Analytics scenarios such as extracting medical insights from collections of electronic health records or identifying emerging problems and vulnerabilities in network traffic. However, many software libraries for Visual Analytics treat time as a flat numerical data type and insufficiently tackle the complexity of the time domain such as calendar granularities and intervals. Therefore, developers of advanced Visual Analytics designs need to implement temporal foundations in their application code over and over again. We present TimeBench, a software library that provides foundational data structures and algorithms for time-oriented data in Visual Analytics. Its expressiveness and developer accessibility have been evaluated through application examples demonstrating a variety of challenges with time-oriented data and long-term developer studies conducted in the scope of research and student projects.

2005-01-01

A turbine generator to be evaluated is a one with 566 MW capacity installed on a reinforced concrete supporting structure having a table deck portion where equipments are installed and columns to support on the table deck. After the initial operation of this turbine generator started, a difference from the initial setting at an installation stage was found at turbine generator in the annual inspection on 1979. The turbine generator foundation (herein after TG foundation) had expanded mainly longitudinal direction, and it was confirmed this expansion occurred due to affected by Alkali-Silica reaction (herein after ASR) according to concrete core samples tests. The measurement for TG foundation such as displacements started at this time. On the other hand, bearing metal temperatures and shaft vibration for the turbine generator have been continuously monitored by supervisory from initial operation. No abnormal alarm or trips by extraordinary metal temperature or axle vibration of the turbine generator due to TG foundation expansion affected by ASR have been arisen. However it is required to confirm sounding of this turbine generator in order to safely operation. The purpose of this paper checked and examined allowable capacity of turbine generator and TG foundation, in order to operate continuously and safely. (authors)

Foundations of Total Functional Data-Flow Programming

Baltasar Trancón y Widemann

2014-06-01

Full Text Available The field of declarative stream programming (discrete time, clocked synchronous, modular, data-centric is divided between the data-flow graph paradigm favored by domain experts, and the functional reactive paradigm favored by academics. In this paper, we describe the foundations of a framework for unifying functional and data-flow styles that differs from FRP proper in significant ways: It is based on set theory to match the expectations of domain experts, and the two paradigms are reduced symmetrically to a low-level middle ground, with strongly compositional semantics. The design of the framework is derived from mathematical first principles, in particular coalgebraic coinduction and a standard relational model of stateful computation. The abstract syntax and semantics introduced here constitute the full core of a novel stream programming language.

Cold war, quantum foundations, and East-West collaboration

Energy Technology Data Exchange (ETDEWEB)

Skaar-Jacobsen, Anja [Niels Bohr Archive, Copenhagen (Germany)

2011-07-01

It is well-known that the cultural cold war changed the ideological line in the Soviet Union from the late 1940s and that this had serious implications for the autonomy of research in genetics and quantum foundations in the East bloc. However, besides the more narrow concern from the point of view of research in quantum foundations, I suggest that the ideological impact on quantum foundations also constituted an obstacle for attempts by Western physicists to bring about a rapprochement between physics in the east and west in general. In connection with re-establishing East-West co-operation between physicists after Stalin's death in 1953 this obstacle needed to be cleared away. In my talk I discuss these issues and how the Institute for Theoretical Physics in Copenhagen came to be an important meeting place for physicists from the East and West from the mid-1950s.

Full Text Available Heavy duty computer numerical control machine tools have characteristics of large self-weight, load and. The insufficiency of foundation bearing capacity leads to deformation of lathe bed, which effects machining accuracy. A combined-layer foundation model is created to describe the pile group foundation of multi-soil layer in this paper. Considering piles and soil in pile group as transversely isotropic material, equivalent constitutive relationship of composite foundation is constructed. A mathematical model is established by the introduction of boundary conditions, which is based on heavy duty computer numerical control machine tools-composite pile foundation-soil interaction system. And then, the response of different soil and pile depth is studied by a case. The model improves motion accuracy of machine tools.

On the influence of the foundation stiffness in the structural dynamic response

International Nuclear Information System (INIS)

Halbritter, A.L.; Koishi, N.; Stukart, R.N.L.

1984-01-01

To consider the influence of the foundation on the structural dynamic analysis, it is usual to represent the foundation stiffness by springs and the damping by snubbers, in the structural model. The stiffness and the damping values of the foundation can be determined by approximate methods based on simplifying assumptions, using, for example, the formula derived from the half space theory or numerical methods. The foundation stiffness has a great influence on the dynamic characteristics of the structure (eigenvalues and eigenvectors), and together with the damping influence the structural dynamic response. In this paper the influence of the foundation stiffness on the floor response spectra of the reactor building of a NPP of 1300 MW PWR of KWU type is studied. (Author) [pt

Field Performance of Recycled Plastic Foundation for Pipeline

Kim, Seongkyum; Lee, Kwanho

2015-01-01

The incidence of failure of embedded pipelines has increased in Korea due to the increasing applied load and the improper compaction of bedding and backfill materials. To overcome these problems, a prefabricated lightweight plastic foundation using recycled plastic was developed for sewer pipelines. A small scale laboratory chamber test and two field tests were conducted to verify its construction workability and performance. From the small scale laboratory chamber test, the applied loads at 2.5% and 5.0% of deformation were 3.45 kgf/cm2 and 5.85 kgf/cm2 for Case S1, and 4.42 kgf/cm2 and 6.43 kgf/cm2 for Case S2, respectively. From the first field test, the vertical deformation of the recycled plastic foundation (Case A2) was very small. According to the analysis based on the PE pipe deformation at the connection (CN) and at the center (CT), the pipe deformation at each part for Case A1 was larger than that for Case A2, which adopted the recycled lightweight plastic foundation. From the second field test, the measured maximum settlements of Case B1 and Case B2 were 1.05 cm and 0.54 cm, respectively. The use of a plastic foundation can reduce the settlement of an embedded pipeline and be an alternative construction method.

Deep foundation rebound instrumentation at the Grand Gulf Nuclear Power Station

International Nuclear Information System (INIS)

Blendy, M.M.; Boisen, B.P.

1978-01-01

Removing an extensive amount of overburden can initiate adjustments in the foundation mass. Rebound adjustments induced by this removal include, in addition to elastic response, elements of visco-elastic and plastic response which have to be taken into account when the foundation is loaded by subsequent construction. The accurate measurement of foundation response can be important in the design and construction of deep foundations and can be essential in the construction of very deep foundations. In 1974, a large foundation excavation was undertaken for the two unit Grand Gulf Nuclear Station. Overburden removal ranged in depth from 65 feet in the turbine area to 110 feet in the containment area. Very long, rod-type Multiple Position Borehole Extensometers measured the rebound. The design of the extensometers, and the dimensions of the installed instruments, are discussed. Graphs are included which show the adjustments measured by each extensometer during the deepening of the excavation. The measured rebound for each transducer package of each extensometer is summarized. The data are compared to predicted values based on a mathematical model developed using laboratory test results and empirical methods. The resulting information forms part of the permanent record of construction for the nuclear power station

Experimental evaluation of a quasi-modal parameter based rotor foundation identification technique

Yu, Minli; Liu, Jike; Feng, Ningsheng; Hahn, Eric J.

2017-12-01

Correct modelling of the foundation of rotating machinery is an invaluable asset in model-based rotor dynamic study. One attractive approach for such purpose is to identify the relevant modal parameters of an equivalent foundation using the motion measurements of rotor and foundation at the bearing supports. Previous research showed that, a complex quasi-modal parameter based system identification technique could be feasible for this purpose; however, the technique was only validated by identifying simple structures under harmonic excitation. In this paper, such identification technique is further extended and evaluated by identifying the foundation of a numerical rotor-bearing-foundation system and an experimental rotor rig respectively. In the identification of rotor foundation with multiple bearing supports, all application points of excitation forces transmitted through bearings need to be included; however the assumed vibration modes far outside the rotor operating speed cannot or not necessary to be identified. The extended identification technique allows one to identify correctly an equivalent foundation with fewer modes than the assumed number of degrees of freedom, essentially by generalising the technique to be able to handle rectangular complex modal matrices. The extended technique is robust in numerical and experimental validation and is therefore likely to be applicable in the field.

We aimed to identify the factors influencing UK medical student applicants' choice of foundation school. We also explored the factors that doctors currently approaching the end of their 2-year program believe should be considered. A cross-sectional study was conducted during the 2013-2014 academic year. An online questionnaire was distributed to 2092 final-year medical students from nine UK medical schools and 84 foundation year-2 (FY2) doctors from eight foundation schools. Participants were asked to rank their top 3 from a list of 12 factors that could potentially influence choice of foundation school on a 5-point Likert scale. Collated categorical data from the two groups were compared using a chi-square test with Yates correction. Geographic location was overwhelmingly the most important factor for medical students and FY2 doctors with 97.2% and 98.8% in agreement, respectively. Social relationships played a pivotal role for medical student applicants. Clinical specialties within the rotations were of less importance to medical students, in comparison to location and social relationships. In contrast, FY2 doctors placed a significantly greater importance on the specialties undertaken in their 2-year training program, when compared to medical students (chi-square; p =0.0001). UK medical schools should make their foundation program applicants aware of the importance of choosing rotations based on specialties that will be undertaken. Individual foundation schools could provide a more favorable linked application system and greater choice and flexibility of specialties within their 2-year program, potentially making their institution more attractive to future applicants.

Investigation on dynamic response with foundation uplift

In order to rationalize the aseismatic design of nuclear power stations, it is necessary to elucidate the characteristics of effective input when the earthquake motion for the design is inputted in the foundations of nuclear power stations. In this study, among the research subjects concerning the reduction of effective earthquake input, regarding the uplift of foundations, its response characteristics and the method of the rational evaluation of earth contact ratio were experimentally examined, and the method of analysis which can evaluate the damping effect due to the uplift was proposed. The experimental method is reported. It was found that accompanying the uplift of foundations, vertical motion was induced, and horizontal motion showed nonlinear response. It was confirmed that the nonlinear response accompanying the uplift can be approximately evaluated by the conventional analysis technique using the S-R model. The current equation for evaluating earth contact ratio is adequate for a soft ground model, and tends to undervaluate for a hard ground model. The S-R analysis model introducing the experimentally obtained characteristics in the dampling coefficient of a nonlinear rocking spring was newly made. (Kako, I.)

Full Text Available The ATP-sensitive K+-channels (KATP are distributed in the tissues coupling metabolism with K+ ions efflux. KATP subunits are encoded by KCNJ8 (Kir6.1, KCNJ11 (Kir6.2, ABCC8 (SUR1 and ABCC9 (SUR2 genes, alternative RNA splicing give rise to SUR variants that confer distinct physiological properties on the channel. An high expression/activity of the sarco-KATP channel is observed in various rat fast-twitch muscles, characterized by elevated muscle strength, while a low expression/activity is observed in the slow-twitch muscles characterized by reduced strength and frailty. Down-regulation of the KATP subunits of fast-twitch fibres is found in conditions characterized by weakness and frailty. KCNJ11 gene knockout mice have reduced glycogen, lean phenotype, lower body fat, and weakness. KATP channel is also a sensor of muscle atrophy. The KCNJ11 gene is located on BTA15, close to a QTL for meat tenderness, it has also a role in glycogen storage, a key mechanism of the postmortem transformation of muscle into meat. The role of KCNJ11 gene in muscle function may underlie an effect of KCNJ11 genotypes on meat tenderness, as recently reported. The fiber phenotype and genotype are important in livestock production science. Quantitative traits including meat production and quality are influenced both by environment and genes. Molecular markers can play an important role in the genetic improvement of animals through breeding strategies. Many factors influence the muscle Warner-Bratzler shear force including breed, age, feeding, the biochemical and functional parameters. The role of KCNJ11gene and related genes on muscle tenderness will be discussed in the present review.

[The foundation of the Dutch Society for Tropical Medicine: an affair of national importance].

Science.gov (United States)

van Bergen, Leo

2009-01-01

The 'Nederlandsche Vereeniging voor Tropische Geneeskunde' (Dutch Society for Tropical Medicine--in short: NVTG) was founded in 1907, a time not only of colonial expansion, but also a time in which the economic interest of the Dutch East-Indies for The Netherlands grew exceptionally. This had its effect on the motivations behind medical aid. Hygienic measures were financially backed because healthy workers had a positive effect on profits. This atmosphere of economic interest and political-military expansion had its effect on the foundation of the NVTG as well. Colonialism was generally approved of, and the goal of the society apart from sociability motives--was to support research into illnesses torturing mainly the Dutch colonies. This was in line with the reasoning that the colonies were rightfully governed by the Netherlands, because the peoples living there had proven not to be able to look after themselves in a proper manner. The foundation of the Society should have been a part of the foundation of an international society for tropical medicine, but this failed. Although internationalism generally was seen as an important feature of science and certainly of medical science, it is not strange this was not seen as a major problem. For it was national and not international reasons that had led to founding the Dutch society. It was the Dutch position as a colonial power that had convinced Dutch tropical doctors a society should be called into being. A generally shared spirit of internationalism had little to do with this unless internationalism is defined as: what others have, we need to have as well, and let us see in international conferences what could be of national benefit. That nevertheless this spirit of internationalism--and not nationalism--is commonly hailed as the main reason behind the foundation, is probably due to the fact that around 1900 nationalism was such a normal state of mind and so fully incorporated in man's way of thinking and acting

2014-01-01

In this study a vibration analysis was performed of an isotropic cylindrical shell submerged in fluid, resting on Winkler and Pasternak elastic foundations for simply supported boundary condition. Love's thin shell theory was exploited for strain- and curvature- displacement relationship. Shell problem was solved by using wave propagation approach. Influence of fluid and Winkler as well as Pasternak elastic foundations were studied on the natural frequencies of submerged isotropic cylindrical shells. Results were validated by comparing with the existing results in literature. Vibration, Submerged cylindrical shell, Love's thin shell theory, Wave propagation method, Winkler and Pasternak foundations. (author)

Dynamics of large rotors on spring supported foundations

Energy Technology Data Exchange (ETDEWEB)

Puttonen, J. [IVO Power Engineering Ltd., Vantaa (Finland)] Luukkanen, P. [Imatran Voima Oy, Vantaa (Finland)

1998-12-31

This article presents some case studies relating to the dynamics of the large machines on spring isolated foundations. The studies comprise both vibration calculations and measurements also introducing the accuracy of numerical methods available in practical engineering. A summary of the pros and cons of spring isolated foundations in power plants is included. The cases described are from the lately built power plants of the IVO-group. The auxiliary feed water pump analysed consists of an electric motor (7 MW), a gear and two pumps. During the trial runs, severe vibrations were observed calling for thorough vibration measurements. The modelling of the whole vibrating entity in the rotating machinery, including the shaft train, oil films of bearings and the foundation is demonstrated by a turbine generator set of 100 MW. Finally, some results of a test comparing the acoustic emission and traditional vibration measurements for recognizing the rub between the shaft and the hydrodynamic bearing are presented.

This paper presents in-situ seismic performance tests of a bridge before its demolition due to accumulated scouring problem. The tests were conducted on three single columns and one caisson-type foundation. The three single columns were 1.8 m in diameter, reinforced by 30-D32 longitudinal reinforcements and laterally hooped by D16 reinforcements with spacing of 20 cm. The column height is 9.54 m, 10.59 m and 10.37 m for Column P2, P3, and P4, respectively. Column P2 had no exposed foundation and was subjected to pseudo-dynamic tests with peak ground acceleration of 0.32 g first, followed by one cyclic loading test. Column P3 was the benchmark specimen with exposed length of 1.2 m on its foundation. The exposed length for Column P4 was excavated to 4 m, approximately 1/3 of the foundation length, to study the effect of the scouring problem to the column performance. Both Column P3 and Column P4 were subjected to cyclic loading tests. Based on the test results, due to the large dimension of the caisson foundation and the well graded gravel soil type that provided large lateral resistance, the seismic performance among the three columns had only minor differences. Lateral push tests were also conducted on the caisson foundation at Column P5. The caisson was 12 m long and had circular cross-sections whose diameters were 5 m in the upper portion and 4 m in the lower portion. An analytical model to simulate the test results was developed in the OpenSees platform. The analytical model comprised nonlinear flexural elements as well as nonlinear soil springs. The analytical results closely followed the experimental test results. A parametric study to predict the behavior of the bridge column with different ground motions and different levels of scouring on the foundation are also discussed.

Developing and teaching the virtue-ethics foundations of healthcare whistle blowing.

Science.gov (United States)

Faunce, Thomas

2004-10-01

Healthcare whistle blowing, despite the benefits it has brought to healthcare systems in many developed countries, remains generally regarded as a pariah activity by many of the most influential healthcare professionals and regulatory institutions. Few if any medical schools or law department health law and bioethics classes, teach whistle blowing in a formal sense. Yet without exception, public inquiries initiated by healthcare whistle blowers have validated their central allegations and demonstrated that the whistle blowers themselves were sincere in their desire to implement the fundamental virtues and principles of medical ethics, bioethics and public health law. In many jurisdictions, the law, this time remarkably in advance of professional opinion, has offered legislative protection for reasonable allegations of whistleblowers made in good faith and in the public interest concerning a substantial and imminent threat to public safety. One reason for this paradoxical position, explored here, is that healthcare whistle blowing lacks a firm virtue-based theoretical bioethical and jurisprudential foundation. The hypothesis discussed is that the lack of this bioethical and jurisprudential substrate has contributed to a situation where healthcare whistle blowing suffers in terms of institutional support due to its lack of academic legitimacy. This article commences the process of redressing this imbalance by attempting to lay the theoretical foundations for healthcare whistle blowing. As a case study, this article concludes by discussing the Personal and Professional Development course at the ANU Medical School where healthcare whistle blowing is a formal part of a virtue-based curriculum that emphasises the foundational importance of conscience. Illustrative elements of that program are discussed.

Realism and Antirealism in Informational Foundations of Quantum Theory

Directory of Open Access Journals (Sweden)

Tina Bilban

2014-08-01

Full Text Available Zeilinger-Brukner's informational foundations of quantum theory, a theory based on Zeilinger's foundational principle for quantum mechanics that an elementary system carried one bit of information, explains seemingly unintuitive quantum behavior with simple theoretical framework. It is based on the notion that distinction between reality and information cannot be made, therefore they are the same. As the critics of informational foundations of quantum theory show, this antirealistic move captures the theory in tautology, where information only refers to itself, while the relationships outside the information with the help of which the nature of information would be defined are lost and the questions "Whose information? Information about what?" cannot be answered. The critic's solution is a return to realism, where the observer's effects on the information are neglected. We show that radical antirealism of informational foundations of quantum theory is not necessary and that the return to realism is not the only way forward. A comprehensive approach that exceeds mere realism and antirealism is also possible: we can consider both sources of the constraints on the information, those coming from the observer and those coming from the observed system/nature/reality. The information is always the observer's information about the observed. Such a comprehensive philosophical approach can still support the theoretical framework of informational foundations of quantum theory: If we take that one bit is the smallest amount of information in the form of which the observed reality can be grasped by the observer, we can say that an elementary system (grasped and defined as such by the observer correlates to one bit of information. Our approach thus explains all the features of the quantum behavior explained by informational foundations of quantum theory: the wave function and its collapse, entanglement, complementarity and quantum randomness. However, it does

Miah, Saiful; Pang, Karl H; Rebello, Wayne; Rubakumar, Zoe; Fung, Victoria; Venugopal, Suresh; Begum, Hena

2017-01-01

Background We aimed to identify the factors influencing UK medical student applicants’ choice of foundation school. We also explored the factors that doctors currently approaching the end of their 2-year program believe should be considered. Methods A cross-sectional study was conducted during the 2013–2014 academic year. An online questionnaire was distributed to 2092 final-year medical students from nine UK medical schools and 84 foundation year-2 (FY2) doctors from eight foundation schools. Participants were asked to rank their top 3 from a list of 12 factors that could potentially influence choice of foundation school on a 5-point Likert scale. Collated categorical data from the two groups were compared using a chi-square test with Yates correction. Results Geographic location was overwhelmingly the most important factor for medical students and FY2 doctors with 97.2% and 98.8% in agreement, respectively. Social relationships played a pivotal role for medical student applicants. Clinical specialties within the rotations were of less importance to medical students, in comparison to location and social relationships. In contrast, FY2 doctors placed a significantly greater importance on the specialties undertaken in their 2-year training program, when compared to medical students (chi-square; p=0.0001). Conclusion UK medical schools should make their foundation program applicants aware of the importance of choosing rotations based on specialties that will be undertaken. Individual foundation schools could provide a more favorable linked application system and greater choice and flexibility of specialties within their 2-year program, potentially making their institution more attractive to future applicants.

Dynamic response of beams on elastic foundations to impact loading

International Nuclear Information System (INIS)

Prasad, B.B.; Sinha, B.P.

1987-01-01

The beam considered is a Timoshenko beam in which the effects of rotatory inertia and shear deformations are included and the foundation model consists of Winkler-Zimmermann type having Hookean linear elastic springs. The analysis is very useful for predicting the dynamic response of structural components of aircraft or nuclear reactors or even runways if that component may be mathematically idealized as a beam on elastic foundation. The effect of rotatory inertia and shear deformation is very much pronounced and hence should not be neglected in solving such impact problems. In general the effect of foundation modulus is to further increase the values of frequencies of vibrations. (orig./HP)

Vibration analysis of viscoelastic single-walled carbon nanotubes resting on a viscoelastic foundation

Zhang, Da Peng; Lei, Yong Jun; Shen, Zhi Bin; Wang, Cheng Yuan

2017-01-01

Vibration responses were investigated for a viscoelastic Single-walled carbon nanotube (visco-SWCNT) resting on a viscoelastic foundation. Based on the nonlocal Euler-Bernoulli beam model, velocity-dependent external damping and Kelvin viscoelastic foundation model, the governing equations were derived. The Transfer function method (TFM) was then used to compute the natural frequencies for general boundary conditions and foundations. In particular, the exact analytical expressions of both complex natural frequencies and critical viscoelastic parameters were obtained for the Kelvin-Voigt visco-SWCNTs with full foundations and certain boundary conditions, and several physically intuitive special cases were discussed. Substantial nonlocal effects, the influence of geometric and physical parameters of the SWCNT and the viscoelastic foundation were observed for the natural frequencies of the supported SWCNTs. The study demonstrates the efficiency and robustness of the developed model for the vibration of the visco-SWCNT-viscoelastic foundation coupling system

Freshwater availability and coastal wetland foundation species: ecological transitions along a rainfall gradient

Osland, Michael J.; Enwright, Nicholas M.; Stagg, Camille L.

2014-01-01

Climate gradient-focused ecological research can provide a foundation for better understanding critical ecological transition points and nonlinear climate-ecological relationships, which is information that can be used to better understand, predict, and manage ecological responses to climate change. In this study, we examined the influence of freshwater availability upon the coverage of foundation plant species in coastal wetlands along a northwestern Gulf of Mexico rainfall gradient. Our research addresses the following three questions: (1) what are the region-scale relationships between measures of freshwater availability (e.g., rainfall, aridity, freshwater inflow, salinity) and the relative abundance of foundation plant species in tidal wetlands; (2) How vulnerable are foundation plant species in tidal wetlands to future changes in freshwater availability; and (3) What is the potential future relative abundance of tidal wetland foundation plant species under alternative climate change scenarios? We developed simple freshwater availability-based models to predict the relative abundance (i.e., coverage) of tidal wetland foundation plant species using climate data (1970-2000), estuarine freshwater inflow-focused data, and coastal wetland habitat data. Our results identify regional ecological thresholds and nonlinear relationships between measures of freshwater availability and the relative abundance of foundation plant species in tidal wetlands. In drier coastal zones, relatively small changes in rainfall could produce comparatively large landscape-scale changes in foundation plant species abundance which would affect some ecosystem good and services. Whereas a drier future would result in a decrease in the coverage of foundation plant species, a wetter future would result in an increase in foundation plant species coverage. In many ways, the freshwater-dependent coastal wetland ecological transitions we observed are analogous to those present in dryland

Foundation Trusts: economics in the 'postmodern hospital'.

Science.gov (United States)

Newbold, David

2005-09-01

Foundation Trust Hospitals are community-controlled health care providers which have increased autonomy about how they produce outcomes for the British National Health Service. Although there is a literature on hospital economics it is unclear how these innovative providers will behave, if they have to compete for scarce resources with other hospitals. This paper reviews some of the earlier theories, such as the neoclassical theory of the firm, and discusses their relevance along with 'newer' economic theories such as the transaction costs and evolutionary theory of the firm, plus organizational and human resources theory, to the performance of Foundation Trusts. Much contemporary health care provision is shaped along modernist lines, using scientific endeavour to maximize the impact on health outcomes and technical and social efficiency. However, there is an increasingly postmodern standpoint--critical of modernity--being taken by both patients and hospital staff, to deconstruct processes in the organizations that serve them. Foundation Trusts are postmodern hospitals insomuch as they (to attract scarce resources in a competitive environment), need to marshal the diverse theories of the firm together in order to provide a mass-customized, quality experience, transparently and at least cost--whilst maintaining a stable organizational culture for staff.

Particularities of flat foundations for offshore wind power plants; Besonderheiten bei Flachgruendungen fuer Offshore-Windenergieanlagen

Interest in offshore wind energy installations has increased significantly in Germany and globally. In Germany only foundation structures secured by piles are currently being constructed. However, a gravity foundation has major advantages in particular because of the self-restoring effect. In this contribution the soil mechanical behaviour of a gravity foundation is described and the currently valid standards and regulations for the dimensioning of the foundation listed. It is clear that regulations for gravity foundations in particular still require development. With regard to the test foundation, which has already been described in detail in previous publications, there follows a brief description of the laboratory programme and a short summary of the latest test foundation results.

Beste, H-J.; Clemente, P.; Conti, C.; D'Ovidio, G.; Nakamura, Y.; Orlando, L.; Rea, R.; Rovelli, A.; Valente, G.

2015-01-01

By the comparison between tests and analyses, the dynamic characterization was performed, in order to obtain the map of elastic modules for soil Colosseum interaction. The accuracy for foundations and soil is lower than for monument, due ti unknown exact geometry underground. For foundations, a high variability was found of elasticity modules, which was referred to variable damage of concrete for cracking in time. For soil layers, different definitions exist, and we are interested in the best. The vibrations produced by trains are depending on the underground geometry too. The analyses are performed with traditional convoys running on Metro B and C, for the vibrations knowledge on RA XLVII and on ground felt by pedestrians.

Analysis of raft foundations for spent fuel pool in nuclear facilities

International Nuclear Information System (INIS)

Subramanian, K.V.; Kashikar, A.V.; Nath, C.; Shintre, C.C.

2005-01-01

Foundation rafts are analysed as a plate on elastic foundation with the representation of the foundation media using the Winkler idealisation i.e. series of linear uncoupled springs. The elastic constant of the Winkler springs is derived using the sub-grade modulus. However, the Winkler approach has limitations due to incompatibility of the deflections at raft-soil interface. The deflection of the raft at the point of contact and the deformation of the foundation media at this point of contact are incompatible in this approach. This particularly influences flexible rafts and further if the foundation media is soil. This paper discusses the analysis of raft, in general, and the analysis of the foundation raft for a Spent Fuel pool facility using 'variable k approach' where deformations at a node and influencing nodes are computed using Boussinesq's theory. The limitations stated above are overcome in this approach. Some studies on the sensitivity of parameters were carried out in the form of variation of moduli of elasticity of concrete and deformation modulus of soil. Analysis is also performed with conventional method using 'Winkler' soil springs. It is concluded that the Winkler model does not correctly predict the behaviour of the mat both qualitatively and quantitatively and could lead to underestimation of soil pressures leading to unconservative design. The approach involving soil structure interaction like the one presented here is hence recommended for important structures like those involved in Nuclear facilities. (authors)

Universics: a Theory of Universes of Discourse for Metamathematics and Foundations

Directory of Open Access Journals (Sweden)

Ioachim Drugus

2016-04-01

Full Text Available A new type of structures called ``universes'' is introduced to subsume the ``von Neumann universe'', ``Grothendieck universes'' and ``universes of discourse'' of various theories. Theories are also treated as universes, ``universes of ideas'', where ``idea" is a common term for assertions and terms. A dualism between induction and deduction and their treatment on a common basis is provided. The described approach referenced as ``universics'' is expected to be useful for metamathematical analysis and to serve as a foundation for mathematics. As a motivation for this research served the Harvey Friedman's desideratum to develop a foundational theory based on ``induction construction'', possibly comprising set theory. This desideratum emerged due to ``foundational incompleteness'' of set theory. The main results of this paper are an explication of the notion ``foundational completeness'', and a generalization of well-founded-ness.

Topological Foundations of Electromagnetism seeks a fundamental understanding of the dynamics of electromagnetism; and marshals the evidence that in certain precisely defined topological conditions, electromagnetic theory (Maxwell's theory) must be extended or generalized in order to provide an explanation and understanding of, until now, unusual electromagnetic phenomena. Key to this generalization is an understanding of the circumstances under which the so-called A potential fields have physical effects. Basic to the approach taken is that the topological composition of electromagnetic field

Science.gov (United States)

Sedin, Vladimir; Bikus, Kateryna; Kovba, Vladislav

2017-12-01

Redistribution of pile foundation forces under successive loading of its elements was investigated under laboratory conditions. A segment of pile foundation model was taken for use in the case study. Load tests on the pile foundation model segment, without joining its elements (pile and plate, which turns into grillage) and based on different combinations of static loadings were conducted. This proved that the loading of a plate causes skin friction on some length of the pile side surface as well as providing additional loading and settlement. Test results have shown that application of successive elements enables the foundation to carry loads up to 13% higher than in the case of a standard pile foundation loading with the same settlement rates.

Krone, Roland; Gutow, Lars; Joschko, Tanja J; Schröder, Alexander

2013-04-01

In the light of the introduction of thousands of large offshore wind power foundations into the North Sea within the next decades, this manuscript focuses on the biofouling processes and likely reef effects. The study explores the macrozoobenthos (biofouling) colonization at an offshore platform which is comparable to offshore wind turbine foundations. A total of 183 single samples were taken and the parameters water depth and time were considered comparing biofouling masses and communities. The blue mussel Mytilus edulis, Anthozoa and the Amphipoda Jassa spp. were the dominant species. The community from the 1 m zone and those from the 5 and 20-28 m zones can clearly be differentiated. The 10 m zone community represents the transition between the M. edulis dominated 1 m and 5 m zones and the Anthozoa dominated 20-28 m zone. In the future offshore wind farms, thousands of wind turbine foundations will provide habitat for a hard bottom fauna which is otherwise restricted to the sparse rocky habitats scattered within extensive sedimentary soft bottoms of the German Bight. However, offshore wind power foundations cannot be considered natural rock equivalents as they selectively increase certain natural hard bottom species. The surface of the construction (1280 m²) was covered by an average of 4300 kg biomass. This foundation concentrates on its footprint area (1024 m²) 35 times more macrozoobenthos biomass than the same area of soft bottom in the German exclusive economic zone (0.12 kg m(-2)), functioning as a biomass hotspot. Concerning the temporal biomass variation, we assume that at least 2700 kg biomass was exported on a yearly basis. 345 × 10(4) single mussel shells of different sizes were produced during the study period. It is anticipated that the M. edulis abundance will increase in the North Sea due to the expansion of the offshore wind farm development. This will result in the enhanced production of secondary hard substrate (mussel shells

Full Text Available Statement of the problem. The review of the technical solutions of the foundation of buildings and structures revealed a number of significant shortcomings associated with the complexity of structures and a low probability of normal functioning in difficult engineering-geological conditions. When designing the building use and design measures that reduce either the amount of strain-tive effects from the base, or their impact on the structure. Experience in construction has shown that it is not always possible to completely prevent the adverse effects on structures from the base. Therefore, their effect on the structure still considered at the design stage. Purpose. On the basis of experimental and theoretical studies to justify the proposed theory of joint work the plate foundation-selfregulators (PFS with the base, including the theory of plasticity (maximum stress state and soil pressure on roofs with. Conclusion. Of all the discussed features of the joint work the PFS with the base surface is more important "arch" effect, since it is the resultant and explains the stress-strain state (SSS for PFS. Increased design resistance at 15-22% is due to the design of the PFS and the special nature of the formation of the overall limit of the SSS of the base with an increase in load to the limit values. For the construction of the PFS by more uniform distribution of the contact stresses in the ground under the foundation, regardless of the power or influence of the deformation, and large outside the proportional relationship between stress and strain. Establish the boundaries of self-regulation can be obtained by carrying out mathematical modeling of changing the compensatory possibilities of the foundation.

Effect of foundation embedment on the response of a multi-story building to earthquake excitation

2018-01-01

Full Text Available During an earthquake, the behaviour of any structure is affected not only by the superstructure response, but also by the response of the soil beneath. Recent structural failure patterns have indicated the significance of soil-structure interaction (SSI effects. The present study focuses on SSI analysis considering the embedment depth of the foundation of a symmetric six stories reinforced concrete (RCspace bare frame building resting on stiff soil and subjected to seismic loading. The finite element analysis software ANSYS v17.2 is used. Time history (TH analysis has been adopted. The Response in terms of lateral displacements, base shear forces, base moments and variation in natural time periods are calculated from the analysis of the soil foundation structure interaction (SFSI model. Results are compared with that obtained from conventional method assuming rigid support at the base (fixed base of the structure. The results show that the SFSI considering different embedment depths are significant in altering the seismic response of the multi-story building (MSB.

We also explored the factors that doctors currently approaching the end of their 2-year program believe should be considered. Methods: A cross-sectional study was conducted during the 2013–2014 academic year. An online questionnaire was distributed to 2092 final-year medical students from nine UK medical schools and 84 foundation year-2 (FY2 doctors from eight foundation schools. Participants were asked to rank their top 3 from a list of 12 factors that could potentially influence choice of foundation school on a 5-point Likert scale. Collated categorical data from the two groups were compared using a chi-square test with Yates correction. Results: Geographic location was overwhelmingly the most important factor for medical students and FY2 doctors with 97.2% and 98.8% in agreement, respectively. Social relationships played a pivotal role for medical student applicants. Clinical specialties within the rotations were of less importance to medical students, in comparison to location and social relationships. In contrast, FY2 doctors placed a significantly greater importance on the specialties undertaken in their 2-year training program, when compared to medical students (chi-square; p=0.0001. Conclusion: UK medical schools should make their foundation program applicants aware

Study on dynamic behavior of large-scale foundation on soft ground, (6)

Sawada, Yoshihiro; Yajima, Hiroshi; Esashi, Yasuyuki; Sakurai, Akio

1983-01-01

Generally, the earthquake motion in the basements of buildings and foundations shows smaller amplitude than that on ground surface. As the cause, there are two interpretations, the interaction of ground and structures and the input loss of earthquake motion due to the restriction by foundations. It is important to urgently clarify this problem in case of the aseismatic design of nuclear power stations at the location of Quaternary ground. For the purpose, the observation of earthquakes was performed with simple flat foundations and in the surrounding ground, in which the effect of locking and upper structures was negligible. The obtained data were compared with the theoretical solutions according to the above two interpretations, thus it was attempted to clarify the mechanism of restricting earthquake motion by foundations. The foundations were a foundation of 30 cm diameter and 2 cm thickness made by improving the superweak ground with nearly zero N-value by cement mixing treatment and a large concrete base of 90 x 45 x 21 m constructed in sandy gravellayer. The mecahnism of restricting vibration was due to the reflection effect of input energy at the boundary between rigid bases and the soft ground right under them, and it can be estimated by multiple reflection theory.

Philanthropy and the nation-state in global health: The Gates Foundation in India.

Science.gov (United States)

Mahajan, Manjari

2017-12-15

In recent years, philanthropic actors such as the Gates Foundation have been understood as commanding sweeping influence in global health. They have been associated with the outsourcing of public health services, shifting of policy priorities, and the eventual sidelining of national governments. This article makes a different argument about the impact of global philanthropic actors. It focuses on the work of the Gates Foundation in India over the last decade and a half, tracing how the foundation initially circumvented the national government but then moved on to a discourse of partnership. Ironically, after an early discounting of the role of the government, the foundation later sought to transition its programmes to the state. The foundation's evolving trajectory reflects its experiences on the ground and also the difficulties of realising its original ambitions. While the foundation's work in India is marked by ebbs and flows, the state's institutions remain constant. The article argues that there is not always a straightforward marginalisation of the government vis-à-vis global philanthropic actors. Actors such as the Gates Foundation, perceived as enormously powerful in global health institutions in Geneva and New York, may have a far more qualified impact in large developing countries such as India.

Theoretical computation background for transformation of foundations using pile drains

Directory of Open Access Journals (Sweden)

Ter-Martirosyan Zaven

2017-01-01

Full Text Available In the design of foundations for buildings and structures of various purposes, including improved risk, weak water-saturated clay soils with low mechanical characteristics are often found on a construction site. One of the possible ways of using them as a foundation is to seal them in various ways, including using pile drains of sand or rock stone material that are capable of both absorbing the load at the base and accelerating the process of filtration consolidation. This paper describes an analytical solution to the problem of interaction between the pile and the mattress with the surrounding soil of the foundation, taking into account the possibility of expanding the pile shaft. Solutions are obtained for determining the stresses in the shaft of the pile drain and in the soil under the mattress. The solution takes into account the influence of the pre-stressed state of the foundation after compaction on the formation of a stress-strain state during the erection and operation of structures. The solutions are relevant for consolidating pile drains made of rubble or for jet grouting piles, the rigidity of which is comparable to the rigidity of the surrounding soil. The paper describes the technique for determining the characteristics of the strength and deformability of the converted foundation and the results of large-scale tests at the experimental site for the construction of a large energy facility in Russia.

Effect of foundation flexibility on the vibrational stability of the National Ignition Facility optical system support structures

International Nuclear Information System (INIS)

McCallen, D.

1997-01-01

Alignment requirements for the National Ignition Facility (NIF) optical components will require a number of support structures which minimize the system displacements and deformations. The stringent design requirements for this facility will result in a system in which vibrations due to ambient environmental loads (e.g. foundation motion due to typical traffic loads, microseisms or nearby equipment) will have a significant, and perhaps predominant, influence on the design of the supporting structures. When considering the total deformations and displacements of the structural systems, the contribution of the foundation to the overall system flexibility must be addressed. Classical fixed-base structural analyses, which are predicated on an assumption of an infinitely rigid foundation system, neglect the influence of foundation flexibility and for the vibration regime in which the NIF structures reside, may result in significant underestimation of the system ambient vibration displacements. In the work described herein, parametric studies were performed in order to understand the potential contributions of soil-structure- interaction (SSI) to optical system displacements. Time domain finite element analyses were employed to quantify the effect of wave scattering by the mat foundation and the effects of inertial SSI due to the rocking of the massive shear wall support structures. A simplified procedure is recommended for accounting for SSI effects in the design of the special equipment structures. The simplified approach consists of applying a scale factor to displacements obtained from fixed base analyses to approximately account for the effects of soil-structure interaction and variable support input motion

Towards an arithmetical logic the arithmetical foundations of logic

CERN Document Server

Gauthier, Yvon

2015-01-01

This book offers an original contribution to the foundations of logic and mathematics, and focuses on the internal logic of mathematical theories, from arithmetic or number theory to algebraic geometry. Arithmetical logic is the term used to refer to the internal logic of classical arithmetic, here called Fermat-Kronecker arithmetic, and combines Fermat’s method of infinite descent with Kronecker’s general arithmetic of homogeneous polynomials. The book also includes a treatment of theories in physics and mathematical physics to underscore the role of arithmetic from a constructivist viewpoint. The scope of the work intertwines historical, mathematical, logical and philosophical dimensions in a unified critical perspective; as such, it will appeal to a broad readership from mathematicians to logicians, to philosophers interested in foundational questions. Researchers and graduate students in the fields of philosophy and mathematics will benefit from the author’s critical approach to the foundations of l...

Three-dimensional analysis for piled raft machine foundation embedded in sand

Directory of Open Access Journals (Sweden)

Mahmood Mahmood

2018-01-01

Full Text Available Three-dimensional analysis for the dynamic response of a piled raft foundation subjected to vertical vibration is presented in this study. The analysis considers several factors affecting the amplitude of displacement for deep foundation such as pile cap embedment, pile cap thickness, relative density of the sand and the boundary effect. A validation for an experimental piled raft model depending on a scale factor of (20 using at (Plaxis 3D computer program was performed. The sand is simulated using Mohr-Coloumb model while the concrete is simulated as linear elastic material. It has been found that embedding the pile cap in the soil and increasing its thickness lead to decrease the maximum amplitude of displacement. Furthermore, the predictions showed that increasing the distance between the foundation and the boundaries and increasing the relative density of the sand can significantly minimize the dynamic response of the foundation.

Quantum foundations in the light of quantum cryptography

International Nuclear Information System (INIS)

Brassard, G.; Fuchs, C.A.

2005-01-01

Full text: Consider the two great physical theories of the twentieth century: relativity and quantum mechanics. Einstein derived relativity from very simple principles such as: 'The speed of light in empty space is independent of the speed of its source' and 'Physics should appear the same in all inertial reference frames'. By contrast, the foundation of quantum mechanics is built on a set of rather strange, disjointed and ad hoc axioms. Why is that? Must quantum mechanics be inherently less elegant than relativity? Or is it rather that the current axioms of quantum mechanics reflect at best the history that led to its discovery by too many people (compared to one person for relativity), over too long a period of time? The purpose of this talk is to argue that a better foundation for quantum mechanics lies within the teachings of quantum information science. We postulate that the truly fundamental laws of nature concern information, not waves or particles. For example, it has been proven, from the current axioms of quantum mechanics, that 'nature allows for the unconditionally secure transmission of confidential information', but 'nature does not allow for unconditionally secure bit commitment' (these are standard classical cryptographic primitives). We propose to turn the table around, start from these two theorems and possibly a few others, upgrade them as axioms, and ask how much of quantum mechanics they can derive. This provocative talk is meant as an eye-opener: we shall ask far more questions than we shall resolve. (author)

Releveling and behavior of strap-retrofitted damaged test foundations exposed to mine subsidence

International Nuclear Information System (INIS)

Marino, G.G.

1997-01-01

Test foundation walls were constructed in an area of planned subsidence. These crawl space-sized block bearing walls were located in the tension zone of a longwall panel. The test walls were 1.2 m (40 ft) long and were vertically loaded on top with soil binds to simulate the weight of a house. As the longwall proceeded past these test foundations, subsidence movements damaged the test structures. These damaged foundations were then structurally and aesthetically repaired by using a steel strap retrofit and applying a cementitious surface coating. The repaired test foundations underwent significant subsequent subsidence as an adjacent longwall was mined beneath. The response of the repaired foundation is summarized in this paper. The steel straps were also used to relevel another set of the test foundations after they were tilted and damaged by subsidence. First, the straps were applied to the block bearing walls, and then wall jacks were used to lift the upper portion of the walls to a level position. This releveling procedure is outlined with the results

Helical piles: an innovative foundation design option for offshore wind turbines.

Science.gov (United States)

Byrne, B W; Houlsby, G T

2015-02-28

Offshore wind turbines play a key part in the renewable energy strategy in the UK and Europe as well as in other parts of the world (for example, China). The majority of current developments, certainly in UK waters, have taken place in relatively shallow water and close to shore. This limits the scale of the engineering to relatively simple structures, such as those using monopile foundations, and these have been the most common design to date, in UK waters. However, as larger turbines are designed, or they are placed in deeper water, it will be necessary to use multi-footing structures such as tripods or jackets. For these designs, the tension on the upwind footing becomes the critical design condition. Driven pile foundations could be used, as could suction-installed foundations. However, in this paper, we present another concept-the use of helical pile foundations. These foundations are routinely applied onshore where large tension capacities are required. However, for use offshore, a significant upscaling of the technology will be needed, particularly of the equipment required for installation of the piles. A clear understanding of the relevant geotechnical engineering will be needed if this upscaling is to be successful. © 2015 The Author(s) Published by the Royal Society. All rights reserved.
