Processes using fluidized bed reactors are well known since 1920, although in some processes like combustion, this equipment only started to be used in the 80's and 90's with special application to installations for electric generation. Fluidized bed process make possible the use of raw materials with quality lower than the materials normally used in similar processes. The fluidized bed technics are not spread out in Brazil yet, where the problems with energetic matrix open the options to use new processes to electric generation. Thermal generation is one of this options, which can use fluidized bed reactor to burn materials like coals and biomasses. The brazilian coals presents high ash and sulfur content fact that disable the direct use in conventional thermoelectric facilities. Therefore, the use of fluidized bed to produce hot gas for power generation is a promissing technique to overcome the use of impure raw materials with high combustion efficiency and energy savings. Mathematical models have proved their efficiency to investigate optimum operational conditions and reproduce virtually the industrial processes. The objective of this work is to develop a computational model that simulate the fluidized bed phenomena considering two phases. The model uses the multiphase concept to simulate the flow in a 3D fluidized bed reactor. Transport equations of mass, momentum and energy are solved by the finite volume method for non-orthogonal system implemented in a complex computational code written in Fortran 90/95. The phases are modeled using continuum mechanics principles where collection of particles is considered identical having a representative diameter and density. This model has been an innovation of fluidized bed study by considering 3D transient features. The results shown good agreements with experimental and computational results previously investigated.


Disclosed is the method of defoaming an aqueous amine gas purification scrubbing solution by stripping gaseous contaminants from the scrubbing solution and then passing a side stream of from about 10% to about 20% of the scrubbing solution through a carbon filter.


The ways in which the various roles of the computer (data logging, control, signal processing, interpretation and dynamic modelling) can be combined to provide powerful measurement methods are discussed with the aid of examples. Pitfalls associated with computer power are considered. The influence of the introduction of microcomputers is traced with particular reference to recent applications in scientific and medical measurements.


Aluminum is one of the primary environmental factors that limit crops production in acid soil.In this study,rice roots were respectively exposed to 0,50,100 and 150mmol·L-1 aluminum stress.The effects of aluminum on the growth of rice root were stuclied.The present results showed that roots growth(root length and fresh weight) of rice decreased with the increase of the concentration of aluminum.The level of cell death of rice root tip and the content of H2O2 in rice root increased.Treatment with dimethylthiourea(DMTU,scavenger of H2O2) decreased the content of H2O2 in rice root.Moreover,DMTU treatments partially alleviated the root cell death and growth inhibition induced by aluminum stress.These results suggested that the effect of aluminum stress on rice root growth could be partly due to the accumulation of H2O2 in roots of rice.


Within the Open Science economy, a major challenge for the practical application of the FAIR principles is represented by numerical factual data. This is a result of the overwhelming big quantity of data sets, as well as of the big variety of used data structures currently used in the different disciplines. This heterogeneity makes it difficult to compare data structures of different origins, as well as the establishment of unique standards for their description through metadata: for instance, the common metadata schema DataCite doesn't include any fields for the detailed description of the study object, other than the inclusion of free-text – thus non controlled – keywords. Under these conditions there are limited possibilities to apply even the first of the FAIR principles, Findability: a directed advanced search of data over a plurality of repositories is currently not feasible. We are seeking a solution to this problem in relation to the typical characteristics of numerical factual data, which are commonly described by reporting quantity names, units, numerical ranges, roles (measured quantity,

If G is a finite subgroup of $GL(n,K),$ K a field of characteristic 0, it is well known that the algebra ${\cal I}$ of polynomial invariants of G is Cohen-Macaulay. Consequently ${\cal I}$ has a subalgebra ${\cal J}$ of Krull dimension n so that ${\cal I}$ is a free ${\cal J}$-module of finite rank. A sequence ($f\sb1,\...,f\sb{n};g\sb1,\...,g\sb{m}$) of homogeneous invariants is a Cohen-Macaulay (or CM) basis if ${\cal J}$ = $K\lbrack f\sb1,\...,f\sb{n}$) and $\{g\sb1,\...,g\sb{m}\}$ is a basis for ${\cal I}$ as a ${\cal J}$-module. We discuss an algorithm, and an implementation using the systems GAP and Maple, for the calculation of CM-bases.


Environmental Impact Assessment (EIA) has been portrayed as a 'frontline' tool in facilitating the transition to sustainability, but research demonstrates that many German stakeholders believe it is failing to achieve its potential in practice. Rather than focusing on the more tangible limitations of EIA practices, the authors argue that the underlying reason it is failing is because the relationship between EIA and sustainable development is inadequately conceptualised. This article, therefore, aims to advance scientific understanding of their relationship by 'unpacking' what sustainable development means for the theory and practice of EIA. The lack of a consensual definition of sustainable development has been interpreted as a significant, if not intractable, barrier to interpreting how EIA can implement it. It is suggested, however, that one way in which EIA makes a significant contribution is by providing a forum in which societal interpretations of sustainability can be debated. Furthermore, a richer conception of their relationship can still be developed, by examining causation in EIA. It is argued that the breadth of ways in which EIA contributes to sustainability has been inadequately appreciated, the importance of certain forms of causation has been significantly underestimated, and that some expectations of what EIA can achieve in practice have been entirely unrealistic. It is postulated that, when such factors are taken into account, EIA can be considered to be operating as a 'frontline' tool in operationalising sustainable development, but in a markedly different manner to conventional expectations. The Contribution of EIA to Sustainable Development: Part 2 – Towards a Richer Conceptual Understanding Der Beitrag zur UVP zur nachhaltigen Entwicklung: Teil 2 – auf dem Weg zu einem umfassenderen konzeptionellen Verständnis Matthew Cashmore and Cordula Nieslony sulted in two polarised approaches to implementing sustainability, the implications of which are of considerable relevance to understanding EIA's contribution. The first approach involves expounding rigorous and comprehensive principles or decision rules for sustainable development (for example, the environmental capital model (Turner 1993)). An inescapable conclusion of such approaches, however, is that there can be no objective, technical method of establishing sustainability principles (Owens & Cowell 2002). This is because their development is inevitably a valueladen process (Bosshard 2000, Owens & Cowell 2002). Nowhere is this more evident than in decisions concerning distributional and gener-


A new method for egg crack detection was proposed on the base of image enhancement by computering gradient and image projection transform.In this method,G gray level image of all egg images were preprocessed by prewitt algorithm and segmented by OTSU algorithm,then usable information was extracted and used to judge whether the egg was cracked one after the processed image had been projection transformed into another field.The results showed that this approch was efficient to detection which its accuracy could reach 95%.


Aim: To examine the laparoscopic skill-degradation effect by investigating whether a long absence from laparoscopic surgery increases laparoscopic surgery time. Methods: Using the Japanese Diagnosis Procedure Combination database from April 2010 to March 2012, data for patients undergoing laparoscopic nephrectomy and nephroureterectomy for malignancy were collected. To regulate the hospital volume effect, the hospitals included in the study were limited to those with hospital volumes of 12-24 per year. Laparoscopic time was assessed by multivariate linear regression analysis including interval days, age, gender, comorbidity, oncological stage, nephrectomy or nephroureterectomy, hospital academic status, and hospital volume. Results: For intervals of ≥ 7 days (3057 cases), 8-14 days (1325 cases), 15-28 days (1424 cases), 29-56 days (711 cases), and ≤ 57 days (332 cases), the median laparoscopic times were 245, 247, 255, 265, and 260 min, respectively (P < 0.001). In multivariate analyses for laparoscopic time compared with interval of ≥ 7 days, 15-28 days, 29-56 days and ≤ 57 days were associated with slightly longer laparoscopic time (+10.5, +16.8, and +18.8 min, all P < 0.01, respectively). Conclusion: Absence intervals of ≤ 15 days can slightly lengthen the operation time, which suggest the existence of mild degree of a skill-degradation effect in laparoscopic surgery.


Tattooing is quite a common fashion worldwide in spite of its traumatism and the introduction of potentially toxic pigments. The most frequent complications include contact dermatitis, granulomas, infections and verrucae [1, 2]. The literature also reports cases of malignant melanoma in tattoos [3–9]. We report the case of a malignant melanoma which formed on a nevus on which a tattoo had been made.


Productive and decent work 1 is the main route out of poverty for most poor people. By making better employment outcomes an MDG target for eradicating extreme poverty, the international community has highlighted the importance of promoting employment, which is also a core objective for several international organisations including the International Labour Organisation (ILO), World Trade Organisation (WTO) and Organisation for Economic Co-operation and Development (OECD). Employment performance is therefore central to the success of poverty reduction strategies and to efforts to enhance development, but it has to be productive and decent paid employment if individuals, the economy and society are to benefit fully. Both the pace and pattern of economic growth matter as well. A rapid pace of growth and increasing labour productivity are needed to generate large numbers of new and decent jobs in developing countries while a broad-based pattern of growth is needed to maximise the participation of and benefits to poor people.


This chapter looks at the various existence of exotica in the Classical, Byzantine, and Islamic periods. Through Egyptian intermediaries, monkeys from elsewhere in Africa reached Minoan Crete and the Cyclades during the first half of the second millennium B.C.E. Dozens of them appear thereafter in wall paintings, seals, and jewelry, engaging in animal and human activities in formal and informal settings. From the seventh century on, gradually expanding colonial and commercial contacts—especially in the eastern Mediterranean—brought exotic experiences back to the Greeks. This gave rise to Greek writing on natural history. Meanwhile, the rise of imperial Rome meant that exotic fauna found themselves inextricably linked with the self-image of the state; any exceptional creatures were reserved as gifts for the emperors. Menageries also existed throughout the Arab/Islamic world from an early date.


1. Variation in spring phenology – like tree budburst – affects the structure of insect communities, but impacts of autumn phenology have been neglected. Many plant species have recently delayed their autumn phenology, and the timing of leaf senescence may be important for herbivorous insects.


The vital energy of heart and liver in physique with congenital natural endowment becomes deficient or suficient easily. The easy attack tendency of maniacal, despondent mental diseases arc the main causes of the symptoms. The common clinical manifestation of maniacal despondent mental diseases is attack of despondent and maniacal condition in turn. if the vital energy of heart, liver is deficient, the despondent symptom will arise, if suficicnt, the maniacal symptom will arise. The easy deficiency, suficiency of vital energy is heart and liver causes attack of despondent and maniacal symptoms. More over, the two types of symptoms of heart and liver take regular attributes of alternative deficiency and suficicncy as symptoms.

In Latin, the gerund and the present participle often function as the predicate of an adjunct clause. In Late Latin, the frequency of such clauses is hypothesized to increase with the ablative of the gerund and to decrease with the nominative of the present participle. This evolution leads to the "gradual replacement of the present participle by the gerund" (Pinkster 2015: 549), whereby the former is ousted from its verbal function and confined to a purely adjectival role. This process is triggered by the "semantic bleaching" of the gerund, whose original manner/instrumental value gradually "weakens" into the default value of the present participle, viz. a temporal one. This paper aims to investigate the functional competition between the two clause types in a corpus of technical texts between the 2nd c. BC and the 6th c. AD. We show that the semantic bleaching of the gerund is not significant in our corpus and hence does not confirm its functional competition with the present participle. We argue that the two clause types have different semantic and pragmatic properties and that these differences remain stable over time.


Information about future job openings for new entrants can be important for those making decisions about what education and training courses to undertake. Such information has the potential to reduce skill imbalances in the labour market. This chapter describes a method used in Australia for producing medium term forecasts of job openings by occupation and industry.


Objective To investigate and analyze the use of antibiotics during perioperative period.Methods 240 medical records in 2007 were collected,and the perioperative use of antibiotics were evaluated by Guiding Principal of the Clinical Application of Antibacterials.Results The rate of antibiotics use in perioperative period was 95.8%,and the average application time was 4.8 d.Cephalosporins was the first choice for clinicians.The preventive use of Quinolones was 36.5%.90.0% of antibiotics use was irrational.Conclusion The unreasonable application of antibiotics during perioperative period included prolonged medication duration,high level of choice and improper selection of antibiotics strategies,and the management of them should be strengthened.


By March of 1957, Hugh Everett and John Wheeler had already completed the extensive revisions that cut the long thesis down to the final, short version that was ultimately accepted. It was now time to distribute the preprint to various prominent physicists for their feedback before publication. This document is the form letter to accompany the preprints, which Wheeler asked Everett to send in a letter a few days later. Also included here is the list of physicists, with addresses, that Wheeler recommended Everett send the thesis and accompanying article to.


The problem of approximating to the fixed points of uniformly Lipschitzian asymptotically psendo-contractive mappings in an arbitrary real Banach space by the modified Ishikawa iterative sequences is investigated.


Interdisciplinary learning enables students to discuss problems and generate creative solutions in a flexible and comprehensive manner. A trend towards more interdisciplinary courses and departments exists in higher education. The use of creative design methods can help people generate many ideas. Interdisciplinary groups can generate innovative solutions through creative design methods by applying knowledge from different fields. According to past teaching experience, when engaging in group work, students were generally willing to cooperate with classmates from different departments. However, when facing the stress of final assignments, they tended to form groups with students from the same department rather than engage in interdisciplinary cooperation. In this study, the students were placed into interdisciplinary groups for the following activities: labeling (visual department labels), taking turns to be group leaders, introducing departments, setting propositions, and giving instant feedback. This increased students' interaction with other students. Students' interdisciplinary awareness was improved through practice drills. After engaging in group work, they no longer resisted interdisciplinary cooperation but were willing to engage in interdisciplinary activities, which increased creative output. The results revealed that intentional interdisciplinary grouping can (1) increase willingness to engage in interdisciplinary cooperation, increase satisfaction with teamwork, and (3) improve learning effectiveness.


Recently, the input interfaces for the PC using the EEG have been studied. The visual evoked potential (VEP) caused by the blinking light is one of waveforms observed in the EEG signal. The brain computer interfaces which based on the transient VEP (TRVEP) analysis and realized the four choices also have been studied. However, now we have been using a large amplifier and AD board. Furthermore, these two devices are expensive. In this study, in order to solve this problem we developed a small and inexpensive device. In addition, we performed comparative experiments of the conventional device and performance.


The performance of a standard model predictive controller (MPC) is directly related to its predictive model. If there are unmodeled periodic disturbances in the actual system, MPC will be difficult to suppress the disturbances, thus causing fluctuations of system output. To solve this problem, this paper proposes an improved MPC named predictive-integral-resonant control (PIRC). Compared with the standard MPC, the proposed PIRC could enhance the suppression ability for disturbances by embedding the internal model composing of the integral and resonant loop. Furthermore, this paper applies the proposed PIRC to PMSM drives, and proposes the PMSM control strategy based on the cascaded PIRC, which could suppress periodic disturbances caused by the dead time effects, current sampling errors, and so on. The experimental results show that the PIRC can suppress periodic disturbances in the drive system, thus ensuring good current and speed performance. Meanwhile, the PIRC could maintain the excellent dynamic performance as the standard MPC.


Self-penalties of the players in a two-person game are studied as a cooperative tool: by committing himself to a penalty in case he plays a particular strategy, a player may improve upon the equilibrium payoff of both players. A complete characterization of this phenomenon is given for mixed equilibria.


Periodic oscillation is observed in transient four‐wave mixing signal in strain‐induced GaAs quantum dots. The oscillation is assigned to biexcitonic beat based on its polarization dependence and its initial phase, and the biexciton binding energy is deduced. Since strain‐induced dots are produced by adding lateral confinement to a quantum well, direct comparison of the biexciton binding energy in 2D and in 0D system is possible. The beat period in quantum dots is found to be shorter than that in quantum well, and the enhancement factor by the reduced dimensionality is 1.5. Magnetic field dependence of the biexciton binding energy is also studied. It is independent of the magnetic field up to 8 T, and exciton g‐factor in the strain‐induced dots is obtained.


The Salt River Pima-Maricopa Indian Community (SRPMIC) of Maricopa County, Arizona, has determined that it needs to further the economic and social welfare of the community. The community has further determined that these needs might be most efficiently met by a profitable business that garners revenues to the community and income to the employees, furthers the community members' skills, and provides employment. The community presently has several entities that perform construction work on the reservation. Because of these successful operations, the SRPMIC believes that it can enter the market of supplying construction services to clients off the reservation. Determining the opportunities and threats in the marketplace, this study analyzes the potential for success of the community performing construction work off the reservation and outlines a strategic plan that describes the steps for implementing a business enterprise.


The Fruit of Solanum sanitwongsei has been used in southeast asia, especially in Indonesia and Thailand as traditional medicine. Ethanol Extract of Solanum sanitwongsei Craib, was evaluated its antihypertensive effect in hypertensive Wistar rats. Male Wistar rats were induced with sodium chloride 2.5% and metylprednisolone 1.5 mg/kg bw oral for 7 days. Hypertensive Wistar rats were given ethanol extract of solanum sanitwongsei for 7 days. Blood pressure elevation of the animals was significantly (p<0.05) decreased by the ethanol extract of Solanum sanitwongsei at the dose levels of 100, 150 and 150 mg/kg bw, oral. Bisoprolol, as a standard drug beta blocker at the dose of 0.0714 mg/kg bw, oral showed significantly (p<0,05) reduced in the elevated blood pressure.


CIN85 is a multidomain adaptor protein implicated in Cbl-mediated downregulation of receptor tyrosine kinases (RTKs). CIN85 binding to Cbl is increased after growth factor stimulation and is critical for targeting RTKs to clathrin-mediated endocytosis. Here we report the identification of a novel polyproline-arginine motif (PxxxPR), specifically recognized by the SH3 domains of CIN85 and its homologue CMS/CD2AP. This motif was indispensable for CIN85 binding to Cbl/Cbl-b, to other CIN85 SH3 domains' effectors, as well as for mediating an intramolecular interaction between the SH3-A domain and the proline-rich region of CIN85. Individual SH3 domains of CIN85 bound to PxxxPR peptides of Cbl/Cbl-b with micromolar affinities, whereas an extended structure of two or three SH3 domains bound with higher stoichiometry and increased affinity to the same peptides. This enabled full size CIN85 to simultaneously interact with multiple Cbl molecules, promoting their clustering in mammalian cells. The ability of CIN85 to cluster Cbl was important for ligand-induced stabilization of CIN85/Cbl/EGFR complexes, as well as for EGF receptors degradation in the lysosome. Thus, specific interactions of CIN85 SH3 domains with the PxxxPR motif in Cbl play multiple roles in downregulation of receptor tyrosine kinases. Here we identified a novel motif in the distal tail of which serves as a high affinity binding site for the SH3 domains of CIN85/CMS adaptor molecules. We also show that CIN85, its three SH3 clusters Cbl molecules, which is a critical step for oligomerization of CIN85-Cbl-EGFR complexes to internalization and efficient degradation of activated EGF can thus function alike G specific controlling receptor for each time three compared same


Cationic amino acid transporter (HGMW-approved gene symbol SLC7A9, solute carrier family 7, member 9) plays a crucial role in amino acid nutrition. In the present study, we describe the cloning and sequencing of porcine . Based on the sequence of porcine deposited in the NCBI (National Center for Biotechnological Information), we identified a putative porcine homologue. Using rapid amplification of cDNA ends (RACE), the full-length cDNA encoding porcine was isolated. The porcine cDNA was 1,680 bp long, encoding a 487 amino acid trans-membrane protein. The predicted amino acid sequence was found to have 88.9% and 87.1% identity with human and mouse , respectively. Real-time RT-PCR indicated porcine transcripts expressed in heart, kidney, muscle and small intestine. The small intestine had the highest mRNA abundance while the muscle had the lowest (p mRNA abundance while the colon had the lowest (p mRNA level was highest on day 7 and 90 in the duodenum (p0.05) and had the highest abundance on day 60 (p0.05). The strongest expression appeared on day 7 in the ileum before weaning, and then decreased till day 30 but rose gradually again from day 60 to 150 (p


The structure of a discharge across a magnetic field in a dusty plasma is analysed. The dust macroparticles are negatively charged, but are unmagnetized because of their high mass. The electrons are highly magnetized, and the ions have intermediate magnetization. This results in different transport rates of the different species across the magnetic field. Depending on the size of the magnetic field, and the relative charge on the different species, the dust grains can be the dominant current carrier. The space charge near the electrodes will then be determined by the relative mobility of the different species. The discharge can operate in one of two modes, a positive space charge (PSC) mode, characterized by a strong cathode fall, and a negative space charge (NSC) mode, characterized by a broad anode fall. Features unique to the dust particles can play a role in the structure of the discharge, such as the variable equilibrium charge on the grains, dependent on the local potential. A fluid model of the different species is used to calculate the structure of the resulting discharge.


The electrical conductivity, the magnetoresistance, the Hall coefficient and the thermoelectric power of single crystal graphite are theoretically calculated as functions of the temperature and magnetic field intensity in the region where lattice scattering is dominant. The values of the electron-phonon coupling constants which fit the theory to the experimental results best are: D 1 =16.2 eV and D 2 =3.73 eV. Here D 1 and D 2 denote the coupling constants related with the in-plane vibration (mode 1) and the out-of-plane vibration (mode 2) respectively. The field and temperature dependence of the magnetoresistance is in qualitative agreement with the measurements by Soule, while the calculated Hall coefficient has the opposite signs to the experimental results. These discrepancies may be closely related with the neglect of the trigonal symmetry of the bands (γ 3 ). The thermoelectric power calculated is positive and increases monotonously with increasing temperature, but there is no available data to be c...


Use of the business-case method to assess the viability of a new business model or an untried product category emphasizes avoiding financial risks—but forgets to consider the risk of not innovating. These authors offer instead some key principles and a methodology for measuring the performance of an innovative project.

The business-case method of proving the efficacy of design thinking is a losing proposition.


Polyacrylate/nano-SiO2 composite was synthesized via semi-continuous emulsion polymerization stabilized with polymerizable surfactant. The influence of synthetic conditions on the properties of polyacrylate/nano-SiO2 composite was investigated in details. Dynamics Laser Scattering (DLS) and Transmission Electron Microscope (TEM) analysis indicated that the latex containing polymerizable surfactant had higher stability and more uniform size. Atomic Force Microscope (AFM) images demonstrated conventional surfactants exhibited higher exudation rate than composite containing polymerizable surfactant. Application in leather finishing showed that latex stabilized with polymerizable surfactant exhibited a remarkably better resistance to water uptake and better performance of vapor permeability than that of latex containing conventional surfactants.


TV conference systems have been widely used recently. A participant of each site proceeds with a TV conference using video image on a screen and voice of a partner site. In this case, a fixed video camera shoots a scene of a site in general. The video image taken by a fixed camera, however, is lacking in changes. Also the fixed camera does not take shots efficiency that the participants of a partner site pay attention. As one of the candidates to avoid these defects, there is a method that the computer-controlled cameras shoots the scene. In this paper we propose an algorithm of shooting the best shot by computer-controlled cameras. The shooting algorithm is mainly decided by estimating an area of the image with high degree of attention, which is given by not only visual information but also auditory information. By using an experimental system, we confirm the effectiveness of our approach by examining a questionnaire from the participants of TV conferences.


The main bacteria causing the spoilage of chilled pork were isolated and identified. The initial proportion of bacteria of chilled pork from different sources were compared. The bacteria isolated and identified were three genus of Pseudomonas and Enterbacteriaceae, two genus of Lactic acid bacterium and one genus of Brochothrix thermosphacta, Micrococcus, Staphylococcal bacteria and Yeast. The proportions of these bacteria in the initial counts are Pseudomonas 25%~26%, Enterbacteriaceae 19%~25%, Lactic acid bacterium 20%~21%, Micrococcus, Staphylococcal bacteria 12%~15%, Brochothrix thermosphacta 12%~13%, Yeast and mould 5%~7%. The dominant bacteria in the initial count was Pseudomonas.


This is a research summary of Virtuosity in Computational Performance, addressing the question: How can a computer, as judged by a human audience, demonstrate virtuosity in computational performances with a physical model of a bass guitar? The proposed plan for this research is to develop a computational performance system which uses case-based reasoning and reflection to produce virtuosic performances with a physical model of an electric bass guitar. Three supporting studies are planned to investigate bass playing, collect performance data and perceptions of virtuosity.


Kidney stones disease is a common disease in human urinary system.In recent years,a method of treatment utilizing high-intensity-focused-ultrasound(HIFU) generated acoustic cavitation has attracted extensive research interest.Engineering experiences show that mechanical properties of materials have a great influence on the effect of cavitation.This article introduces an experimental research on the resistance of artificial kidney stones against acoustic cavitation generated by HIFU. Artificial stones with different mechanical properties have been made.In certain ultrasonic sound field parameters,a series of HIFU stone crushing experiments have been undertaken.Erosion rate was defined by mass/volume loss of the stones over time.Preliminary results are presented in this paper.


The study of the Nambu dynamical system has led to the con-clusion that the Nambu tensor is decomposable if the Funda-mental Identity is to be satisfied [1-9]. This has the immedi-ate consequence that there is a single multiplet and therefore,if the original dynamical system is described by N variables,then the manifold is N dimensional and irreducible exceptfor the singular points where it is zero-dimensional. This isexpressed by stating that the leaves are either of maximal di-mensionality or zero-dimensional. A complete classificationof the Nambu tensor in the neighborhood of a singular pointhas been achieved [10]. Under the conditions that define aNambu manifold, the study of this dynamical system is com-plete and this chapter of mathematical physics can be consid-ered closed.Substantial changes must be incorporated if the dynami-cal system is required to admit more than a single multiplet,so that a situation similar to the Hamiltonian scheme is con-ceived. It is by now well established [11-16] that if a de-scription admits a group of


A field experiment was conducted at Agriculture college farm Raichur, University of Agricultural Sciences, Raichur, Karnataka to study the influence of different agrochemicals on morphological parameters and yield and yield components of chilli variety. The experiment was laid out in randomized complete block design with 3 replications during kharif season 2018. The experiment consisting of 9 different agrochemicals treatment along with a control i.e., T 1 : Gibberellic Acid (GA 3 ) @10 ppm, T 2 : Naphthalene acetic acid (NAA) @10 ppm, T 3 : Methyl Jasmonates (Me JA) @ 0.5mM, T 4 : T 2 + T 3 , T 5 : Cycocel @ 1000 ppm, T 6 : Nitrobenzene @ 10 ppm), T 7 : Brassinosteroides @ 0.15%, T 8 : T 5 + T 7, T 9 : Control. Among the treatments, NAA @ 10ppm recorded significantly higher number of fruits (146.33) over all other treatments followed by GA 3 and Brassinosteroids (137.67 and 135.33). However, the treatments CCC, Nitrobenzene and combination of CCC and brassinosteriods (128.33, 106.00 and 106.67) did not differ significantly among themselves. Lowest yields (50.67) were recorded in control. However, the treatments GA 3 and brassinosteriods and CCC were on par with each other. The treatment NAA @ 10ppm recorded significantly higher number of fruits (9.42 cm) followed by GA 3 (9.13 cm) and Brassinosteriods (8.46 cm). However, the treatments CCC (8.41 cm), Nitrobenzene (8.18 cm) and combination of CCC and brassinosteriods (8.17 cm) did not differ significantly among themselves. The treatment NAA @ 10ppm recorded significantly higher yield (904 kg ha -1 ) over all other treatments followed by GA 3 and Brassinosteriods 855 and 847 kg ha -1 , respectively. However, the lowest yield (496.67 kg ha -1 ) was recorded in control.


In recent decades, abundant methods for targeted tumor cell immunotherapy have been developed. It was recently discovered that excellent curative effects observed in hematological tumors cannot be achieved in solid tumors, as serious side effects will occur. These are all derived from engineered adaptive immune cells, the use of which will bring limitations. γδT cells have a unique ability to respond to a variety of tumor cells while linking innate immunity and adaptive immunity, and thus, they are an ideal source of therapeutic allogeneic cells. This review introduces strategies that can optimize the clinical application of γδT cells to provide novel ideas for adoptive immunotherapy in the future.


This is part three of a three part article on the Value of an IT Chargeback System. Parts one and two were published in Volume 15, Number 3 and cover the IT Survey scope, project overview and purpose, and a detailed explanation of the responses. Part three focuses on summarizing the results in an attempt to create benchmarks. IT Chargeback Survey Background During my thirty years in financial management, I do not recall a single article questioning the value of general ledger and transfer pricing systems. They have always been viewed as necessary financial systems for conducting business in order to report organizational expenses and profitability. They are considered requirements for implementing "responsibility accounting", a financial discipline as sacrosanct as net present value analysis of investments. However, when discussions in the literature or office turn to responsibility accounting and transfer pricing for Information Systems (IS), there is occasionally some question about the value of such a system. This system is commonly referred to as the "chargeback" system. The value of chargeback has been questioned in terms of "Is it worth the money?" "Is it an effective (cost control) tool?" "Do we devote too much time and effort towards it?" Chargeback has been criticized for costing too much and not being understandable (and therefore ineffective). Nowhere in the literature have I ever read what it is specifically that is not understandable, other than the infamous term "EXCP". Nowhere has an author expressed in quantitative terms how much the chargeback process costs and what criterion is used to show that it is "too much". No article has ever given the slightest indication that the author understands the breadth and depth of information that companies acquire from their chargeback systems. Most authors, like many individuals in the IS client community, believe that the only use or value of chargeback is to allocate cost for responsibility accounting or cost control purposes. To satisfy this void in our industry, I conducted a survey of 213 financial institutions companies in order to shed some light on why there is a different attitude about chargeback systems. Is it valid? Should we do something about it? What can be done? Specifically, the survey attempts to: * Define "value" * Understand what value, if any, does chargeback provide * Recognize the various perceptions of chargeback value within a single company * Identify quantitative and qualitative evidence that supports or refutes the literature written to date about the value of chargeback * Provide field research on the value of chargeback for future discussions and more extensive surveys Who participated in the survey? The survey results are from a 26-question survey that was mailed to 213 companies. Sixty-seven (67) companies participated in the survey. This was a 31% response rate. Seventy-four percent (74%) of the participants were from four economic sectors-financial institutions (37%), utilities (15%), government (12%), and manufacturing (10%). Participants were mostly from large and medium size IS installations. Thirty-seven percent (37%) of the companies had annual IS budgets exceeding $80 million and 45% had IS budgets of $20-80 million. Benchmarks for Chargeback Systems What percentage of IS expenses are intentionally allocated or charged back to customers? 90% of the companies follow a full cost absorption pricing policy in that they attempt to recover 100% of their IS expenses through chargeback. One company charged back less than 65% of their cost and one company charged back more than 100% of their cost. Which of the following IS functional areas are included in the total IS expenses used for chargeback purposes: centralized operations, distributed processing, data network, voice network, and application programming? Over 75% of the companies had all five functional areas reflected in their IS expenses. …


Data compression plays a vital role in multimedia devices to present the information in a succinct frame. Initially, the DCT structure is used for Image compression, which has lesser complexity and area efficient. Similarly, 2D DCT also has provided reasonable data compression, but implementation concern, it calls more multipliers and adders thus its lead to acquire more area and high power consumption. To contain an account of all, this paper has been dealt with VLSI architecture for image compression using Rom free DA based DCT (Discrete Cosine Transform) structure. This technique provides high-throughput and most suitable for real-time implementation. In order to achieve this image matrix is subdivided into odd and even terms then the multiplication functions are removed by shift and add approach. Kogge_Stone_Adder techniques are proposed for obtaining a bit-wise image quality which determines the new trade-off levels as compared to the previous techniques. Overall the proposed architecture produces reduced memory, low power consumption and high throughput. MATLAB is used as a funding tool for receiving an input pixel and obtaining output image. Verilog HDL is used for implementing the design, Model Sim for simulation, Quatres II is used to synthesize and obtain details about power and area.

We study the Kondo effect in a single-electron transistor device realized in a single-wall carbon nanotube (NT). The $K\text{\ensuremath{-}}{K}^{\ensuremath{'}}$ double orbital degeneracy of a NT, which originates from the peculiar two-dimensional band structure of graphene, plays the role of a pseudospin. Screening of this pseudospin, together with the real spin, can result in an SU(4) Kondo effect at low temperatures. In order to have such an exotic Kondo effect it is crucial that this orbital quantum number be conserved during tunneling. Experimentally, this conservation is not obvious and some mixing in the orbital channel may occur. Here we investigate in detail the role of mixing and asymmetry in the tunneling coupling and analyze how different Kondo effects, from an SU(4) symmetry to a two-level SU(2) Kondo effect, emerge depending on the mixing and/or asymmetry. We use four different theoretical approaches to address both the linear and nonlinear conductance for different values of external magnetic field. Our results point out clearly the experimental conditions to observe exclusively SU(4) Kondo physics. Although we focus on NT quantum dots (QDs) our results also apply to vertical quantum dots. We also mention that a finite amount of orbital mixing corresponds, in pseudospin language, to having noncollinear leads with respect to the orbital ``magnetization'' axis which defines the two pseudospin orientations in the carbon nanotube QD. In this sense, some of our results are also relevant to the problem of a Kondo QD coupled to noncollinear ferromagnetic leads.


Although trees absorb part of the radiation emitted by the soil, the biomass may be itself an emitter as the aboveground portion of the plants may contain Ra. Ashes of the branches of birch, fir, spruce, larch, and other trees may contain 1.5 to 3 times more Ra than the ground. Such abnormally high Ra concentrations in the above-ground portions of trees growing in U-bearing soil may thus create gamma anomalies'' of 0.4 to 0.9 mu C/hr at a height of 40to 50 m above the ground. For calculation, the forest areas are divided in 3 horizontal layers: the crest, the trunks, and the dead ground cover. Equations were derived for determining the dose rate attributable to these layers. Three factors affect the aerial logging: specific geophysical processes, noted especially in acid forest soils, which tend to deplete the U minerals at a depth from 0.5 to 1 m; absorption of Ra in the above-ground portions of the vegetation, creating biochemical anomalies; and absorption of the gamma radiation, emitted by the soil, by the vegetation.

Under the time background of comprehensively promoting the rule of law, the historical background of alternating between old and new legal culture in rural areas, and the social background of the market economy, both opportunities and challenges coexist in rural legal construction. Under the new situation,we should raise the rights thinking to guide the rural legal construction, reconstruct the law popularization and education work mechanism, reform the rural conflict resolution mechanism, construct agriculture-related tort warning and supervision mechanism, restrict power with right, in order to promote the overall progress of rural legal construction system.


Radiative processes are substantially altered by the presence of forest canopies, further affecting snow energetics during wintertime. In situ measurements of subcanopy radiation can help improve process‐scale understanding of these complex interactions, which are needed to further constrain and improve land surface models. In this study, a custom‐made cable car was used to measure incoming and outgoing, shortwave and longwave radiation below an evergreen forest stand. Hemispherical photographs taken concurrently from the cable car measured view fractions of shaded snow, sunlit snow, and bare ground. With this setup it was possible to quantify diurnal and seasonal radiation patterns together with their potential drivers at high spatiotemporal resolution. Measurements were performed between January and May 2018, along a 48‐m transect in a discontinuous needleleaf forest in the Swiss Alps. Analysis of diurnal radiation patterns revealed a strong linear relationship (R = 0.94) between outgoing shortwave radiation and sunlit snow‐view fraction, highlighting shading as the main control on the subcanopy shortwave radiation budget. Measurements of outgoing longwave radiation were strongly controlled by the snow cover extent, with locations of diminished snow cover showing an increase in outgoing longwave radiation of up to 60 W/m2. The subcanopy radiation budget was shown to be dominated by shortwave radiation when surrounding canopy structure and the position of the sun allowed for direct insolation of the forest floor, but longwave radiation was the dominating component in the absence of direct insolation.


Simple analytical models are introduced that significantly enhance the ability to understand and rationalise the nature of bonding interactions depicted by domain-averaged Fermi hole (DAFH) analysis. The examples presented show that besides shedding new light on the role of electron-sharing in ordinary two-centre two-electron (2c-2e) chemical bonds that are well represented by the classical Lewis model, the proposed approach also provides interesting new insights into the nature of bonding interactions that go beyond the traditional Lewis paradigm. This is, for example, the case of 3c-2e multicentre bonding, but a straightforward extension of the approach also reveals for direct metal-metal bonding the existence of a completely new type of bonding interaction that involves the mutual exchange of electrons between the lone pairs on adjacent metal atoms.

The behaviors of the C/SiC composites under the space environment are introduced,including atomic oxygen and cryogenic conditions.Related researches show that the carbon phase in the C/C-SiC composites is sensitive to the atomic oxygen.The atomic oxygen has little influence on the mechanical properties of the C/SiC composites.The coupled oxidation by atomic oxygen and oxygen show a serious degradation upon the C/SiC composites.Under the cryogenic environment in the space,the tensile strength of the C/SiC composites will be reduced,and then recovered.And its damage mode is similar to that in the high temperature.Meanwhile,the weakness of the current research is put forward,and the future direction in this field is proposed.


The effect of plant growth regulators like gibberellic acid (GA 3 ), indole butyric acid (IBA) and indole acetic acid (IAA) on the soapnut (Sapindus trifoliatus Vahl.) seed germination was studied. GA3 was found to be more effective in improving the seed germination in soapnut than either IBA or IAA.


BACKGROUND
We reported previously that maternal betaine promotes hepatic IGF2 expression in F1 offspring rats through hypermethylation of IGF2/H19 imprinting control region (ICR). Yet, it remains unknown whether this acquired trait can be transmitted to F2 generation.

OBJECTIVE
This study was aimed to determine whether dietary betaine supplementation to grand dams affects the hepatic IGF2 expression in F2 rat offspring and how it is related to alterations in DNA methylation.

METHODS
F2 rat offspring derived from grand dams fed basal or betaine-supplemented diet (10 g kg ^-1) were examined at weaning. Serum IGF2 concentration was measured with ELISA. Hepatic expression of IGF2, together with other proliferation and apoptosis markers, was determined by using quantitative PCR, Western blot and immunohistochemistry. The methylation status of IGF2/H19 imprinting control region (ICR) and the promoters of IGF2 gene was detected by MeDIP-qPCR.

RESULTS
The maternal betaine-induced up-regulation of hepatic IGF2 expression in F1 rat offspring was transmitted to F2 generation. F2 rats from betaine group demonstrated enhanced hepatic IGF2 expression at both mRNA and protein levels, in association with higher serum IGF2 concentration. No alterations were observed in ICR methylation of IGF2/H19 locus, while hypomethylation was detected in promoters of IGF2 gene in betaine group.

CONCLUSIONS
These results indicate that maternal betaine enhances hepatic IGF2 expression in F2 rat offspring through modification of DNA methylation on IGF2 promoters. This article is protected by copyright. All rights reserved.


Quantum walks (QWs) are one of the fundamental concepts in quantum information science, being an essential component for various new applications. Implementing QWs using integrated photonic waveguide lattices allows for realizing long evolution times, for exploring novel lattice geometries, and even for controllable coupling to the environment. This tutorial gives an introduction to the field of on-chip QWs of single photons and photon pairs featuring non-classical two-photon correlations.


This paper aims to examine euphemisms used to evaluate the appearance and personality of characters in Korean and Chinese from a contrastive linguistic perspective. In this paper, in consideration of various factors such as culture, etiquette, religion, ethnicity, and psychology in daily communication process, any expression that prevents the other party from being offended or makes him/her/them pleasant and comfortable is defined as 'euphemism (expression)'. On the base of the notion 'euphemism', this paper contrasts and analyzes the expression methods of Korean character evaluation euphemisms and Chinese character evaluation euphemisms, and describes the common and differential points of the two languages. People react sensitively to topics related to appearance or personality, and the evaluation tends to be negative, so the main analysis target of this paper is the expressions that talk around the point. In addition, the analysis target is to express even positive evaluations better. Appearance evaluation was divided into "face," "height," "body," and "aging," and personality evaluation was divided into "talkative" "impatient" "stubborn" "good at flattering" "stupid" and "slow". In succession, it was presented by dividing it into common expressions between Korean and Chinese, expressions that exist in Korean but do not exist in Chinese, expressions that exist in Chinese but do not exist in Korean, and expressions used differently in Korean and Chinese.


This paper briefly reviews earlier as well as recent approaches of Indian Social Stratification System and there relevance in present era. Much of what is known about Social Stratification in India is based on studies conducted in early and middle part of the 20 th century. There is a lot of literature available on the theme of social stratification in India. In fact, the most researched area in the Indian sociology deals, directly or indirectly with the social stratification or caste. In this regard, the Indian society has been studied both by the local sociologists as well as the alien sociologists. The focus of these studies has been on the origin, dynamics, implications and change in the Hindu caste system excluding Muslims from their studies. Hence there is a requirement of a study of Social Stratification among Muslims in India as well as in Kashmiri society.

Purpose: Ophthalmic prisms are routinely used to measure ocular deviation. However, large measurement errors could be induced when a prism is not accurately positioned at its calibration position. We report a simple way to minimize the errors. Methods: We measured powers of prisms and plastic prisms at their calibration position and at angles the prism was rotated away from the calibration position. Glass prisms that have power of 20, 25, 30, 40, 50, and 60 prism diopters (PD) and plastic prisms that has power of 20, 25, 30, 35, 40, 45, 50 PD were used. To minimize the errors, we developed a pair of prism frame so that the prism can always be positioned accurately. Results: We have demonstrated large errors induced by rotating glass prisms and plastic prism away from their calibration position. Larger errors were recorded with glass prisms than with plastic prisms. The measurement errors are significant even with a small angle rotation for a large power glass prism. For instance, a 10-degrees rotation of a 50PD glass prism produces an error of 30PD. However, measurements errors were minimized when the prism frame was used. Conclusion: It suggests that the glass ophthalmic prism should be abandoned and the use of ophthalmic prisms in strabismus measurement should be standardized with assistance of the prism frame.


Plane LTCC substrates can be produced in zero-shrinkage technology by pressure-assisted sintering. The application of axial pressure during sintering supports densification, enhances co-firing of different materials and restrains deformation. However, the sintered surfaces are affected from the release tapes and setters used in the pressure-assisted sintering process. In this study, the effect of release tape particle size on the surface properties of sintered substrates was investigated. Moreover, the substitution of release tape by the use of a vitreous carbon setter was tested. Surface roughness and sheet resistances of metallic thin-films on the respective samples were determined. It was found, that roughness of the substrates is not directly correlated with the adequacy of the surface for thin-film deposition. Compared to a freely sintered sample with an average roughness (Ra) of 0.31 μm, pressure-assisted sintering created smoother surfaces using fine-grained tapes (Ra = 0.18 μm) and rougher surface...


. Introduction The alkali metal oxides Na2O, K2O, Li2O and Rb2O crystalizes in the cubic antifluorite (anti-CaF2-type) structure [1], which xhibits fast ion conduction, a property useful in solid-state bateries [2,3], gas detectors and fuel cells [4,5]. However, despite he role it plays in geosciences and its potential technological tility. From the experimental point of view, Li2O, Na2O, K2O nd Rb2O crystal have been extensively studied experimentally 6–17]. Various researchers have undertaken several theoretical tudies of this crystal family. From theoretical point of view, Dovesi t al. [18] calculated the lattice constants and elastic properties of i2O, Na2O and K2O at zero pressure have been reported by using artree–Fock linear combination of atomic orbital method (LCAOF). This method (LCAO) is also applied by Cancarevic et al. [19] o study the stability of the alkali metal oxides under pressure. ∗ Corresponding author at: Laboratory Physico-chemistry of Advanced Mateials, University of Djillali Liabes, BP 89, Sidi-Bel-Abbes 22000, Algeria. el.: +213 7 72 53 44 47.

All rights reserved. The electronic band structures of these materials at ambient conditions were discussed by Zhuravlev et al. [20]. and Eithiraj and co-workers [21] using the self consistent pseudopotential method (PP) and tight-binding linear muffin-tin orbitals (TB-LMTO), respectively. The Wannier function based LCAO formalism has been reported by Shukla et al. [22] on Li2O and Na2O compounds. Moakafi et al. [23] have performed a detailed investigation of structural, electronic and optical properties of alkali metal oxides at normal and under pressure conditions using FP-APW+lo method. S.M. Alay-e-Abbas et al. [24] applied the first-principles study of structural and electronic properties of alkali metal chalcogenides: M2Ch [M: Li, Na, K, Rb; Ch: O, S, Se, Te]. To the best of our knowledge, there are no earlier theoretical calculations for the elastic and thermodynamic properties under high pressures and temperature for these compounds. It is therefore timely to investigate these properties of Na2O and K2O compounds in order to provide reference data for the experimentalist and to complete exciting theoretical works on this fascinating class of materials, using the full-potential augmented plane-wave plus local orbitals (FP-APW+lo) method. The rest of the paper is arranged as follows. In Section 2 we give a brief description of computational methodology employed in this study. Section 3 deals with the results and their discussion.

ABSTRACT In order to improve the management effect of agricultural sustainable development, this paper uses the Internet of Things technology and machine learning technology as the basis to study the agricultural sustainable development platform. Simultaneously, this paper studies the architecture of wireless sensor nodes and networks oriented to complex agricultural habitat conditions. Moreover, in view of the harsh environment of data collection in agricultural production sites and the higher requirements for network robustness, this paper designs a new type of intelligent sensor network equipment. It is used to effectively reduce the number of tasks undertaken by routing and the completeness of data in a large covered agricultural base area, and to ensure the efficiency and reliability of network data. In addition, this paper combines the needs of sustainable development of smart agriculture to build a smart agriculture platform based on Internet of Things technology and machine learning, and design experiments to verify the performance of the system platform constructed in this paper. From the experimental research, it can be seen that the system constructed in this paper basically meets actual needs.

We consider a real scalar field in de Sitter background and compute its thermal propagators. We propose that in a dS/CFT context, nontrivial thermal effects as seen by an `outside' observer can be encoded in the anomalous dimensions of the d=3 Ising model. One of these anomalous dimensions, the critical exponent η, completely fixes a number of cosmological observables, which we compute.


The present author recently presented an alternative scenario for the tectonic development of the SE margin of the Bohemian Massif based on field studies of the Thaya Dome (Batik 1999). In the present paper, the tectonic evolution of the Svratka Dome is described and F. E. Suess's classic con- cept (1912) of Moldanubian nappe displacement over the Moravicum unit is discussed. The weaknesses of Suess's concept are shown, which pertain mainly to the character of the detachment planes and the amount of time assumed for all the supposed processes. An alternative tectonic scenario is that the Svratka Dome, consisting of Proterozoic granitoid and its overlying mantle, had already formed during the Cadomian orogeny. After Early Paleozoic erosion, its exposed nucleus was covered by Early Paleozoic basal siliciclastic sediments, which in turn are overlain by Devonian clastic and carbonate deposits and Early Carboniferous shales and greywackes. During the Variscan orogeny, which occurred from the Late Carboniferous to the Permian, a freshly consolidated and metamorphosed tectonic block was thrust along a steeply dipping plane over the Brunovistulicum. The Variscan phase continued by flat shears with eastern vergency. The last tectonic deformation events with western vergency affected the Svratka Dome during the Alpine orogeny.


The City of Vernon is located in the semi-arid Okanagan Valley 175 km north of the international border. Annual precipitation averages 35 cm, daily temperature averages in July and January are 20°C and-5°C, respectively, and the area has an accumulated heat sum of about 2000 degree days on a 5°C base. Vernon's frost-free growing season is about 170 days. Vernon has irrigated nearby managed and wild grasslands with treated municipal effluents for the past 16 years with little or no discharge to nearby waterways. Vernon's relatively warm, dry climate coupled with a well developed effluent irrigation system, available lands, and a need to experiment with other uses for the nutrient rich wastewater led to the establishment of a 13.6 ha demonstration and research plantation complex in 1988. Site preparation began in fall 1987 with a glyphosate spraying, followed by plowing. In spring 1988 the site was thoroughly disked and a solid set aboveground irrigation system was installed. Forty thousand cuttings of selected hybrid clones were planted in pure clonal and mixed clonal blocks at two initial spacings. Western conifer and eastern broadleaf species were also outplanted in small plots near the poplar plantings. A UBC forestry graduate student (George Nercessian) has used a portion of the poplar plantings to satisfy the following objectives: 1) to determine ground water quality characteristics under tree stands versus pasture, 2) to quantify nutrient cycling dynamics in an irrigated hybrid poplar stand, 3) to measure clonal and clonal mix growth responses to varying irrigated levels, and 4) to estimate individual tree and stand growth parameters at varying plant densities. A thesis addressing these objectives is now available. Additional objectives of the Forest Service research staff and the City of Vernon include examining the postulated advantages of fast-growing tree stands compared with pasture grass culture for the utilization of municipal effluent: 1) trees can be managed on ground topograph-ically and edaphically ill suited for forage management; 2) the deeper root system penetration of trees should improve percolation and reduce surface runoff probability; 3) a high leaf area index coupled with a large aboveground surface area (stems, branches, and foliage) should result in greater evaporation and transpiration rates and thus greater wastewater disposal/utilization rates; 4) the longer growing season of some of the fast growing hybrid 196 Ecology and Management of B.C. Hardwoods cottonwoods should result in longer irrigation seasons; and 5) irrigation system operation and maintenance …


The announcement of the discovery of Peking Man in 1927 caused great interest among scientists and produced excellent copy for newspapers, which confidently announced that the "missing link" had been discovered. Despite later discoveries, Sinanthropus pekinensis remains a respected member of the pantheon of evolutionary landmarks. But very few persons today could identify the discoverer, and fewer still would know any more about him than his name. Davidson Black was a Canadian physician, professor of anatomy at Peking Union Medical College from 1919 to his death in 1934. His diagnosis of Sinanthropus pekinensis , initially made in 1926, was based on evidence derived from two fossil teeth. Extensive training in comparative anatomy, including a course of study with Elliott Smith in Manchester, served Black well. Many scientists were hesitant to accept the anatomist's judgment based only on such scanty material. However, Black was convinced he was right, and subsequent finds at

The Rapid Upper Limb Assessment (RULA) survey is a posture-sampling tool used specifically to examine the level of risk associated with upper limb disorders of individual workers. This paper examines the relationship between RULA's postural scoring system and measures of surface electromyography (EMG), self-reports of discomfort, and job attitude questionnaires. Twenty participants each performed a 30-min typing task on a computer in 3 working postures based on RULA's scoring system. A statistically significant difference was found only in perceived discomfort. The perceived discomfort results demonstrated that RULA was able to identify "high risk" postures. The next question we need to ask is, does perceived discomfort result in tissue damage, or does tissue damage yield discomfort?


This research outlines a research study wherein an implementation of the activity-based costing (ABC) approach for cost management in a railway transport enterprise is addressed. ABC is an efficient technique for enhancing the quality of provided services and process complexity of certain railway companies, executing its activities at a regional or international scale. It is one of the new costing approaches that eliminate the inaccuracies and deficiencies of the traditional costing system. Compared to other costing techniques, considerable change lies especially in the way of assigning indirect cost units to activities based on actual causations, and subsequently, assigning activities to the very cost items by the intensity of their consumption. Furthermore, this approach allows decision-makers to identify specific cost item in terms of determining ways of how they can be managed. The main objective of this work is to elaborate a particular study with a draft application of the ABC method encompassing a description of procedure steps, along with relevant quantifications, as well as summarising the results obtained.

This study examined the effects of an instructor's use of video casting as a nonverbal emotional cue in synchronous discussion sessions on students' social presence, satisfaction, and learning achievement. A quasi-experimental design was used to evaluate the effect of video casting in a synchronous virtual classroom. The research setting was a 100% online master's degree program within a university located in the midwestern United States. Thirty-three students participated in the experiment. The results showed a significant positive effect of the video casting on students' feeling of instructor copresence. No significant effect of video casting was found on either students' satisfaction or learning achievement.


• When treating a stain, be sure to blot the area rather than scrub. Scrubbing can cause pile distortion, fiber damage and may cause the stain to spread. For semi-solids, gently scrape with a rounded spoon. Hard scraping with a sharp knife can break fiber and damage the pile. Solid spills should be broken up and vacuumed until completely removed. If the spill is still fresh, blot the area with a dry white cloth or white paper towel until you have removed as much of the spill as possible. If a stain remains, use a spot removal agent.


I'm not a big fan of musicals. I am, however, a fan of the music of Stan Rogers, the great Canadian folksinger and songwriter who was the driving force behind the Canadian folk music revival in the 1970s and early 1980s. I'm also a member of the Mulgrave Road Co-op Theatre, which is located in the town of Guysborough, in northeastern Nova Scotia, and is dedicated to creating original theatre about the part of the world that Stan Rogers' family was from, the area that he named "Fogarty's Cove". In fact, the connection is closer than that. Like Stan Rogers, and like the Mulgrave Road Co-op, I found my creative inspiration in the landscape, seascape, and people of the Chedabucto shore. Like Stan Rogers, I am from Ontario, but have family connections with that shore – the man who made Rogers his first guitar, his uncle Lee Bushell, happens to be my wife's uncle, too, by marriage. And like both Stan Rogers and many members of the Co-op, I am concerned about what it means to come from away and make art out of the "raw materials" of a picturesque and culturally rich but economically troubled area at a time when the death of the fishery threatens a whole way of life. I am concerned about the folksinger, playwright, or theatre company as offshore dragger.


Although most theoretical calculations of quantum wells with non-square profiles assume that material composition is varied continuously, it is more common in experiment to grow digital alloys. We compare the Rashba spin-orbit interaction of triangular wells using continuous, discrete, and digital alloying profiles in (001)-grown triangular InSb/Al_f(z)In_(1-f(z))Sb, finding a very large difference between digital alloying and the others, including a sign change in the Rashba spin-orbit coupling. We find that the interface contribution to the Rashba spin-orbit coupling is much larger in the continuously- and discretely-alloyed triangular quantum wells than in the digitally-alloyed triangular wells, in which it is almost completely absent. The electric field contribution, however, is quite similar in all three systems. Due to a much stronger doping dependence in all three systems, the electric field contribution dominates at higher dopings, although the very large offset due to the near absence of interface contribution in digitally-alloyed wells persists.


The expanding use and increased complexity of hydrological runoff models has given rise to a concern about overparameterization and risks for compensating errors. One proposed way out is the calibration and validation against additional observations, such as snow, soil moisture, groundwater or water quality. A general problem, however, when calibrating the model against more than one variable is the strategy for parameter estimation. The most straightforward method is to calibrate the model components sequentially. Recent results show that in this way the model may be locked up in a parameter setting, which is good enough for one variable but excludes proper simulation of other variables. This is particularly the case for water quality modelling, where a small compromise in terms of runoff simulation may lead to dramatically better simulations of water quality. This calls for an integrated model calibration procedure with a criterion that integrates more aspects on model performance than just river runoff.

"logistics talent demand" has always been one of the research hotspots in academia and industry in China since the Chinese universities began to enroll undergraduates of logistics related subject in 2001.We sort out the main literature which discussed "logistics talent demand" since 1988.The development situation of the field has been described.Two kinds of focal problems are summed up,i.e.the state of classification and demand for logistics talent and the extent of logistics talent lack.At the same time,the different points of view are compared.On this basis,the research direction which should be paid attention to in the future is put forward.


In coastal areas, even in the absence of any disturbance, ocean waves feel the effect of the seabed. This perturbation, function of the local water depth d, causes the variation of almost all their characteristic parameters. Shallow water, is divided into two areas: the intermediate zone (zone lift or area shoaling : area before the bathymetric breaking) and Swash and Surf areas (area after breaking). In the shoaling area, the wave amplitude will gradually increase and their profile is hereby amended while their wavelength decreases. To take into account nonlinear effects generated by the action of the seabed on the deformation of the free surface of the ocean, we used the Saint-Venant equations with topography term (Green Naghdi equations) to model the variations of these parameters according to the local water depth from the intermediate zone to the point of breaking depth. The results show that the amplification of the height is proportional to d− 1 4 while the remaining wavelength decreases proportional to the square root of the local water depth d. This seabed action also induces a phase delay in the wave propagation.


Acylation of amino acid beta-naphthylamides with protected (Boc) amino acidisobutylcarbonic acid mixed anhydrides resulted in each case in the formation of some undesired by-product: an isobutyloxycarbonylamino acid beta-naphthylamide. The amount of this second acylation product was particularly high, with the hindered amino acids valine and isoleucine as carboxyl-components. The nature of the amino component had no major influence on the extent of this side reaction.


Premature Ovarian Failure (POF) is a heterogeneous syndrome characterized by Hypergonadotropic Hypogonadism that affects about 1% of women younger than 40 years old, while an incidence of 1/1000 is reported in women younger than 30 years old. [1] This hormonal disorder is caused by the loss of the ovarian response towards the pituitary gonadrotropins synthesis (FSH and LH) that are secreted according to the inhibitory feedback between hypothalamus, pituitary gland and gonads.


As results of analysis the author suggests models of intrafarm relations in agricultural production co-operatives. The variety of models allows to choose those of them that to a greater extent correspond to the specific conditions of co-operative activities.

Traditional rice wine consist of Lin-fan rice wine and Tan-fan rice wine. Lin-fan rice wine is famous for cooling cooked rice with sprinkling cold water, while is famous for cooling cooked rice with spreading-cooling naturally. The traditional brewing craft of Shaoxing rice wine uses fermented mash by Lin-fan method as seed starter, and brews with Tan-fan method. This paper introduced the use of koji, wheat koji, seed starter of Lin-fan rice wine and the brewing process with Tan-fan rice wine in detail.


This paper traces the complex relationship between classical literature and Christian doctrine in the first four centuries. In the earliest period of Christianity, we can identify two attitudes of Christians towards Greek literature: the hostile attitude shown by Tatian, Theophilus, and Tertullian, and the openness to Greek culture and philosophy demonstrated by Justin the Martyr, Athenagoras of Athens, and Minucius Felix. A notable change happened in the Alexandrian milieu when Clement of Alexandria and Origen started considering Greek classics the embodiment of an authentic Christian spirit. In keeping with Origen, Basil of Caesarea realized a good synthesis between Greek thought and Christian faith. Noting germs of divine revelation in ancient Greek thought, Christian authors took the tools of Greco-Roman criticism and ancient philosophy to develop their doctrine.


Introduction: The Dried Blood Spot sampling (DBS) method gives patients and health care workers the opportunity for remote sampling using a drop of blood from a fingerprick on a sampling card which can be send to the laboratory by mail. Laboratory analysts frequently reject DBS samples because of poor sampling performance, which delays adequate monitoring of a patients' blood drug concentration. We developed a web-based application (Web-app) measuring the quality of DBS at the moment of sampling using a smartphone or computer. The patient takes a picture of the blood spot using a smartphone, uploads it into the Web-app and the Web-app determines the spot quality (sufficient or insufficient). When an insufficient spot is produced the Web-app asks the patient or health care worker to resample until a sufficient spot is produced. We hypothesize that the use of this app will reduce rejection rates of DBS samples in clinical practice. We aim to measure the performance of this Web-app before implementation of this app in clinical practice. Materials & Methods: The Dried Blood Spot App is a responsive web-based App accessible in the browser on smartphone, tablet or desktop pc. The app uses HTML5, Javascript and CSS technology. The results of the app was compared to a golden standard consisting of the combined judgment of two analysts with extensive experience in DBS analysis. Based on rejection rates observed in clinical practice performance qualification was set at 95% accurate evaluation. A samples size of at least 186 spots was required for qualification of the app. Samples were collected by a trained phlebotomist using the same sampling method the patients use at home. These samples were photographed and analyzed using the Web-app. Results: 221 samples were collected on 204 different cards from 181 different patients. The app showed a performance of 90.0% with 4.1% false positives and 5.9% false negatives. False negative results will lead to (unnecessary) patients resampling until a sufficient spot is created and therefore will not lead to delayed monitoring. False positives will lead to sending in insufficient quality spots by the patient leading to delayed monitoring. Conclusion: Although performance of 95% was not met, the current version of the Web-app will lead to a rejection rate of 4.1% DBS samples and is feasible for clinical application. The app will be implemented in clinical practice in the near future.


This study investigates how hand-held computer algebra systems may be used to complete undergraduate mathematics course work tasks. Core university mathematics courses are examined in detail using a question classification scheme that describes the style of a question, rather than the syllabus topic. The majority of the tasks examined could be completed directly using the device. Surreptitious use of the hand-held device would subvert the intentions of the course designer.


ABSTRACT In light of Levinas' conceptualization of the face of the Other, I reread the final showdown scene in Don DeLillo's White Noise. Firstly, I delineate how Jack's egoism renders Mink, who is unmistakably the Other, less human. Through the act of killing, Jack hopes to nullify Mink's otherness and incorporate it into the same as his life credit. Focusing on Jack's role change from killer to savior, I then explain how he moves out of his interiority and welcomes the face of the Other. His gaze at Mink's face helps him see the latter's vulnerability and his own as well. It is right at this Levinasian moment that he sees and is moved by the face of the Other. Finally, I point out that through his ethical relation with Mink, Jack starts to welcome the faces of many Others and embrace the forming of meaningful human relations. The witnessing of embodied vulnerability demands ethical responses to the Other, which would hopefully offset the troubling tendency of aestheticizing disasters as DeLillo observes happening in his time and dutifully represents in his writing.


The article claims that the concept of spirit or of incorporeal substance is a key concept in the thought of St. Augustine. It first recalls how the concept of spirit, which Augustine learned to conceive from the Platonists in Milan, permitted Augustine to extricate himself from Manicheism. Augustine, after all, was one of the very first in the Latin West to be able to think of God and of the soul as incorporeal The paper shows how Augustine used the concept of spirit in arguing against the corporealism of the Manichees and goes on to show from the Letters of Augustine how the bishop of Hippo used the concept of spirit against the Arians, how he held the spirituality of the soul as a fixed point of knowledge about the soul, how he used the concept of spirit to help Consentius to think correctly about God, to help Evodius to think correctly about the Trinity, to answer Volusians questions about the incarnation, and to answer Italica's question about seeing God with the eyes of the body. In conclusion, the paper claims that the concept of a spiritual substance is one of the lasting elements of Neoplatonism in the thought of Augustine.


This article exposes the striking similarities between the debate within youth work of the imposition of a curriculum and that within criminal justice of the imposition of a 'What Works' agenda, notably in relation to young offenders in Scotland . At the heart of both debates lies a perceived shift in emphasis away from the needs of young people themselves, towards a rhetorical, evidence-based professionalism based on the directives of politicians.


South-Eastern Europe was, at the beginning of the modern-day tourism, in the 1960's, a well-defined area of states. With the exception of Greece, all had communistic governments. Yugoslavia decided to open borders, invite tourists and enrich their hard currency income. According to UNWTO Yugoslavia was in 1980's listed among the 10 most visited countries of the world. Through the eyes and experiences of a tour operator and academician, the paper will elaborate on tourism characteristics in three time-frames: 1.) in the historically unified space; 2.) in the contemporary fragmented space and 3.) in the post-industrial globalized space. Personal impressions will be enriched with results of own research and from young scientists' mentorship. The Fall of the Iron Curtain, the strive for national/ethnic sovereignty, the inclusion of most of the East-European periphery into the EU, the uprising of the middle class in some Euro-Asian and Latin American countries, the change of the air travel mode, the growing cruising industry, the experience thirsty and adrenalin searching population and the health- and environment conscious social groups have again made the tourist destination South-Eastern Europe a territory worth to discover. The fragmented space of the former Yugoslavia is divided into 7 nation-states, crisscrossed by approximately 6326 km of semi-open, often not defined borders where on approximately 252 border crossings tourist must identify himself and declare custom goods. Despite it, will most countries in 2015 of the region report best economic results of the tourism industry ever. In addition to the pull-effect for the Europeans – namely the warm waters of the Mediterranean - sightseeing tourism of Asians is enriching outstanding features of cultures and nature. Historical capitols and towns, countries' outstanding natural specifics, and dominant cultural sites register Asian visitors near the top of the foreign nation's tourist list. The future of the region for the tourism industry lies in the promotion of cross-border development and in the increase of the awareness of sustainable development of tourism industries' complexity. Tourism development can only be tolerated to an extent where it would not kill the inviting nature, the authentic culture and itself. Regulating millions of visitors in protected sites of nature and UNESCO heritage places is the task for tourism developers of the future.


This second article of a two-part series gives some useful guidance for epileptics in competitive cycling, and argues that, with patience and the appropriate medication, an epileptic can race with the best cyclists. For an abstract of the first part, see IRRD E106849. The factors affecting the granting of a British Cyclists' Federation (BCF) racing cycling licence for epileptics include: (1) the causes of the epilepsy; (2) the ability to control attacks; (3) the period of time free from attacks; (4) specific factors leading to attacks; (5) regular supervision of the epileptic; and (6) good compliance with treatment. Each case is judged on its individual merits. It seems that, after long-term control has been achieved with medication, the risk to epileptics taking part in cycling sports are relatively small, and to some extent predictable and acceptable. Despite beliefs to the contrary, flashing lights, such as sunlight, and hyperventilation only rarely cause epileptic attacks during cycling. While trying to allow as many epileptics as possible to take part in cycling sports, it is equally necessary to protect other competitors from potential hazards. It is usually necessary to wait some time before granting a racing licence.


Lithium metal batteries (LMBs) have attracted wide attention due to their high energy density. However, flammable organic carbonate electrolytes are associated with severe parasitic reactions and huge safety hazards for LMBs. Herein, a smart temperature‐responsive electrolyte is presented that demonstrates two distinct polymerization behaviors in LMBs. Through an anionic polymerization triggered by lithium metal, this electrolyte forms a favorable polymer protection layer on lithium anodes at ambient temperature, leading to a reversible Li plating/stripping behavior over 2000 h, and dendrite‐free morphology even under a current density of 10 mA cm−2. On suffering from thermal abuse, this electrolyte can be rapidly transformed from liquid into solid by a thermal free radical polymerization, thus realizing significant improvements in safety performance without internal short‐circuit failures thus achieving safe operation even at a temperature of 150 °C. It is noted that no thermal runway occurs even at an extremely high temperature of 280 °C. It is believed that this study not only offers new valuable insights in interfacial chemistry of electrolytes, but also opens up new avenue to develop safe LMBs.


—Recent database research has focused on in-memory databases, which can be used in mixed workload scenarios, enabling OLTP and OLAP queries on the same database en- gine. These compressed column-oriented database systems use a differential store concept to enable fast inserting and require a merge process to compact the data periodically in a compressed main partition that is changed by the merge process only. This characteristic feature calls for a re-evaluation of the performance of inverted indices. In this paper we present a use case for an inverted index in a column-oriented in-memory database system to reduce the total costs of query processing in a mixed workload environment. We evaluate the benefits and drawbacks of using the index structure to answer queries and the costs of maintaining the index, especially during the merge process. An analytical model is introduced to compute the theoretical cost of index scans. Furthermore a comparison between different index maintenance strategies is presented. The theoretical findings are verified in a prototypic implementation within the HYRISE database system. Our contributions are an analytical framework to evaluate the benefit of an inverted index during query execution, the verification in an in-memory database system, and an evaluation of different index maintenance strategies. From the presented findings we conclude that indexing can be an efficient instrument to meet the performance requirements in a mixed-workload and main memory-based environment.


The partial cross section, the satellite branching ratio, and the angular-distribution asymmetry parameter for simultaneous photoionization and excitation to the n = 2 states of the He/sup +/ ion have been measured in the 67.5--90-eV photon-energy range. In the nonresonance regions (67.5 eV< or =h..nu..< or =69.5 eV and 75 eV < or =h..nu..< or =90 eV), the asymmetry-parameter values have been used to infer the ratio of the 2p cross section to the 2s cross section. These results indicate that the He/sup +/(n = 2) satellite is predominantly 2p near threshold, in agreement with the experimental and most of th


The observed diversity of statistical characteristics along genomic sequences is the result of the influences of a variety of ongoing processes including horizontal gene transfer, gene loss, genome rearrangements, and evolution. The rate at which various processes affect the genome typically varies between different genomic regions. Thus, variations in statistical properties seen in different regions of a genome are often associated with its evolution and functional organization. Analysis of such properties is therefore relevant to many ongoing biomedical research efforts. Similarity Plot or S‐plot is a Windows‐based application for large‐scale comparisons and 2D visualization of similarities between genomic sequences. This application combines two approaches wildly used in genomics: window analysis of statistical characteristics along genomes and dot‐plot visual representation. S‐plot is effective in detecting highly similar regions between two genomes. Within a single genome, S‐plot has the ability to i...


The approach to creation of the general theory of the University using the metaphor "university as technology" has been considered in the paper. The heuristic opportunity and contents of this metaphor has been discussed, examples of its empirical verification have been given.


An infinite capacity single server queueing system is considered, to which messages consisting of a variable number of fixed-length packets arrive at the rate of one packet per slot ('train arrivals'). Assuming geometrically distributed message lengths, an exact closed-form expression for the probability generating function (pgf) of the buffer contents is obtained.
