The response of carbonate rocks to hypervelocity impact remains a controversial subject within the impact commu-nity. Many questions remain to be answered, such as the relative importance and role of impact melting versus decomposition. Here, we present the results of an analytical SEM study of carbonate-bearing impact-melted materials from Meteor Crater, Arizona.


ABSTRACT Compound 1, which incorporates a hex-5-enyl group on a quinone methide precursor, has been used to demonstrate that NaHSO3 in 50% isopropyl alcohol exhibits electron transfer reactions. There is a signifi- cant solvent effect associated with this system since NaHSO3 in aq. NaOH showed very few products typical of an electron transfer system, while 50% isopropyl alcohol by itself at 150°C provided some of the typical products. The electron transfer ability of the 50% isopropyl alcohol/NaHSO3 system increases with increasing temperature but is less than that of aqueous anthrahydroquinone at similar temperatures.


Moving target tracking is a hot research spot of computer vision and applied in various fields. In this paper, a new tracking method base on sparse optical flow is put forward. In this method, targets are tracked through calculating the movements of Harris corner points, rather than the movements of all pixel points. Experiments results show that the tracking effect of this new method is pretty good. Tracking accuracy can reach more than 80% in most experimental conditions. And according to other peoples research production, experiments based on dense optical flow are done to compare with the new method proposed in this paper. The comparison results show that the new method has high calculation efficiency. This indicates that the method has feasibility and practical value.


This paper presents an optimization procedure for selecting the best controller gain for an adaptive optics system. The procedure uses an ARX identification of the open loop atmospheric data to model the atmospheric effects and sensor noise. The closed loop system incorporates the adaptive optics system dynamics, the identified atmosphere model and the controller. The gain is found using a parameter optimization of the closed loop system performance.


Introduction Human beings have to change their perceptions and values towards sexuality, homosexuality and means for richness through prostitution, gambling and drug trafficking if they would like to avoid many serious maladies spread among human societies in the East and West such as HIV and AIDS. Both HIV and AIDS are evidently related to the abuses of human sexuality and drug addiction. "The major causes behind HIV/AIDS epidemic that is ravaging the globe is [sic are] homosexuality, drug injecting practices and sex with multiple partners. It has become one of the major health problem worldwide. Physicians and big pharmaceutical companies are feverishly busy in finding cure for this deadly disease." (Bhat 2004: 67). Some human beings have used the vice and evil means such as prostitution, gambling and drug trafficking to gain the material prosperity and richness because they have been greatly influence by materialism rather than spiritualism. For sure, materialism is incapable of bestowing happiness to human beings and their communities.For the change to take place gradually and effectively, human beings have to turn to theological anthropology. Basically theology is the study of God and other religious topics and anthropology is the study of man or humans. The term "theological anthropology" is a combination of the two disciplines namely theology and anthropology or a combination of the two doctrines namely the doctrine of God and the doctrine of man. Professor David Norman who designed the course entitled "Theological Anthropology" described.....


The enantiomeric ligands (R,R)- and (S,S)-bis(o-anisylphenylphosphanyl)methane (R,R-22 and S,S-22) and (R,R)- and (S,S)-bis(phenyl-m-xylylphosphanyl)methane (R,R-23 and S,S-23; dppm*), were treated with [Cu(NCCH3)4](BF4) and AgBF4 to produce the binuclear complexes [Cu2(dppm*)2(NCCH3)4](BF4)2 or [Ag2(dppm*)2](BF4)2, respectively. Then, these complexes were used as building blocks to prepare the first P-chirogenic 1D coordination polymers {[M2(dppm*)2(dmb)2](BF4)2}n [dppm* = (R,R)-22, (S,S)-22, (R,R)-23, (S,S)-23, M = Cu, Ag, dmb = 1,8-diisocyano-p-menthane] where M is part of the backbone of the polymer chain. The isostructural nature of these new polymers with the achiral parent polymers, {[M2(dppm)2(dmb)2](BF4)2}n (M = Cu, Ag), was unambiguously demonstrated with a combination of methods including 1H NMR, chemical analysis, UV/Vis spectrometry, emission spectroscopy and emission lifetime measurements. The structure of the bimetallic complex [Ag2(R,R-23)2](BF4)2 was solved by X-ray crystallography, and all enantiomeric complexes and polymers were characterized by circular dichroism spectroscopy.

: The purpose of this study was to assess the effects of appearance satisfaction, self-esteem, and interpersonal relationship satisfaction of university students on employment stress. a total of 394 male and female students attending universities in Seoul, Gyeonggi, Cheonan, and Daejeon to the survey questionnaire. Two research questions were established; Research Question 1: Are there differences in appearance satisfaction, self-esteem, interpersonal relationship satisfaction, and employment stress of university students according to demographic characteristics?, Research Question 2: Do appearance satisfaction, self-esteem and interpersonal relationship satisfaction of university students affect employment stress? From the survey, appearance satisfaction, self-esteem, and interpersonal relationship satisfaction were higher on average in the 20-22-year-old group, and employment stress was lower in the 20-22-year-old group than the rest of the age groups. Moreover, appearance satisfaction and interpersonal relationship satisfaction had effects on employment stress in contrast to self-esteem, which did not affect employment stress. Therefore, this study dealt with the employment stress by evaluating the impact of appearance satisfaction, self-esteem and interpersonal satisfaction on college student's employment stress, and aimed to provide basic data on factors that affect employment stress. Despite the meaningfull results, the follow-up studies were suggested as follows. First, this was self-reported questionnaire designed in this study so that the participants were more likely to respond in socially desirable ways. In subsequent studies, the shortcomings of the self-report questionnaire need to be overcome by combining qualitative and quantitative studies. Second, since this study was conducted only on university students in certain areas, it is difficult to generalize the results, and the range of samples and areas needs to be expanded in subsequent studies.


Abstract Different experimental techniques and measures of line breadth have been employed to estimate the average crystallite size of magnesium oxide powders over a range of values. The limitations of these methods of crystallite size determination are outlined and, in particular, the validity of assumptions commonly made in line profile analysis is discussed. From a comparison of data obtained using Stokes′ correction with values given by less rigorous methods, the best correction function for the elimination of instrumental broadening is determined. Data from x-ray diffraction, electron microscope and nitrogen adsorption studies of the powders are compared and their usefulness considered.

Dallenbach layer is composed of an absorbing magnetic-dielectric layer attached to a perfect electric conductor (PEC) sheet. Under linearity and time invariance (LTI) assumptions Rozanov has established analytically a sum-rule trade-off between the absorption efficacy over a predefined bandwidth and the thickness of the layer, that is the so-called Rozanov bound. In recent years several proposals have been introduced to bypass this bound by using non-LTI absorbers. However, in practice, their implementation may be challenging. Here, we expose additional hidden assumptions in Rozanov's derivation, and thus we introduce several new sum rules for LTI layer absorbers that are not covered by the original Rozanov's criterion, and give rise to more relaxed constraints on the absorption limit. We then, demonstrate practical LTI designs of absorbing thin layers that provide absorption beyond the Rozanov's bound. These designs are based on the replacement of the original PEC boundary by various types of penetrable impedance sheet.


The novel Ever in the End of the Earth demonstrates that under the environment of the contemporary market economy, a medical graduate student's embarrassment, puzzlement, bitterness and shakings in the process of inheriting and insisting on Chinese scholars innate values and outlook on life. Finally he became a "forced nihilist". However, this kind of "forced nihilist" is really the reflection of some of the contemporary intellectuals. The works express a query to the effectiveness of the traditional spiritual resources and put forward a question of using what to save humanism.

Calligraphy is one of the most famous traditional art in China. The Calligraphy copying practice is the inevitable phase when learning Calligraphy. Calligraphy character has structure and stroke attributes, such as length of stroke and the position distribution of subpart, which can identify each certain character. In this paper, we propose a graph neural network-based algorithm which can measure the similarity between two Calligraphy characters according to structure and stoke. Experiment shows that the proposed method gives satisfied results with respect to the similarity measurement for the Calligraphy copying practice.

The concrete pump truck integrates transportation with pouring process ,which is characterized with flexibility, facility and celerity in civil engineering. As for the concrete pump truck, the arm system is the most important because the rationality of the arm directly influences the performance and pouring position of the truck in its application in civil engineering. For the arm system of the concrete pump truck, the movement of the arm system and the hydraulic cylinder are analyzed respectively with multi-body dynamic theory. By using numerical arithmetic to resolve the dynamic equation, the terminal track of the arms is analyzed. It shows that the kinetic equation built by multi-body dynamics can describe the dynamic characteristics of pump truck exactly.


Besides the wind energy resource analysis and wind turbines arrangement,the power transmission programme design was also play an important role in wind farm project. Unlike the general transmission lines project of traditional power grid,the main function of collecting power lines project for the wind power farm was to gather the power energy of all wind generators,distributed it to the low voltage winding of step-up station ,and then synchronized with the power grid by interconnecting with the system bus. Due to the wind power farm was one of distributed new energy sources,the investment of wind turbine equipments was much more expensive. It was very necessary to make a whole technology and economic analysis of collecting power lines project for economizing the cost of construction and enhancing the rationality of wind power farm project.


In recent years, thanks to a growing understanding of achievable component quality and increased design flexibility of component geometry using additive manufacturing technologies, selective laser melting (SLM) has been growing in popularity among decision-makers and technologists in various industries. In particular, manufacturers of industrial gas turbines and associated maintenance units have contributed to changes in the intended use of SLM technology. A few years ago, it was still regarded purely as a prototype technology, but is now increasingly used as a manufacturing process within industrial small-scale production. The technological and economic success of the few applications to date, for example the injection nozzle for the newest generation of Leap-1 engines by General Electric or the reconditioning process for turbine parts that arose from cooperation between General Electric and Inspire AG, are significantly based on the advantages of SLM technology outlined above. In relation to conventional manufacturing technologies, it is important to understand that the relatively small number of applications does not constitute exceptions to the rule and that profitable success of SLM technology holds in future. To this end, it is necessary to continue scientific explorations into connections in the SLM process which are yet unknown and still poorly understood. The insights obtained should be used to derive process optimisations that will contribute to the further success of SLM technology. The present thesis conveys a more profound procedural understanding of the processability of the nickel base superalloy IN738LC using SLM. Motivated by previous observations of the appearance of hot cracks in the processing of IN738LC using SLM, the mechanism for the formation of hot cracks is derived based on an empirical and a simulative study. In the core of the empirical study, the occurring hot cracks are characterised according to their position, orientation and density. It is shown that only intergranular solidification cracks occur in the SLM microstructure of IN738LC, which are always oriented transverse to the scanning direction. With increasing scanning speed, a decrease in hot crack density and an increase in porosity within the investigated microstructures are observed. By analysing the chemical composition localised at a grain boundary by means of Atom Probe Tomography, indirect knowledge about the chemical composition of a high crack surface can be derived. It can be clearly shown that of all chemical elements, the element zirconium (Zr) accumulates in particularly high concentrations on hot crack surfaces. The results of the empirical research series are supplemented by the results of two simulation studies. The element Zr can be used as a driver for the widening of the solidification

Parallel to the advancement of practical use cases in computers, the trend toward collaborative ontology engineering is accelerating. Both domain experts and ontologists must collaborate in collaborative ontology engineering processes. However, the bulk of domain experts are not computer experts (i.e. lawyers, medical doctors, bankers, etc.). Question and Answer on Linked Data (QALD) is a suggested method for noncomputer domain experts to engage with the ontology increments as they evolve. Existing QALD methods and systems, on the other hand, have a number of drawbacks, including significant setup requirements, domain dependence, and user discomfort. As a result, a new QALD algorithm and QALD system designed with the usage of First Order Logic (FOL) are presented in order to address the shortcomings of current QALD mechanisms. The suggested FOL based, QALD mechanism was tested quantitatively and qualitatively over three distinct ontology increments. This experiment had an overall acceptance rate of 79 percent from all stakeholders. Keywords—First order logic; linked data; ontologist; iterative framework


It is worth approaching how poetic creation can get out of its low. Three abuses in its creation such as shallow expressions, vulgar words and erotic writings are to be stopped. Moreover, the form and content should be continuously probed into. The content of New Verse must be close to fact, life and people themselves, and it also tries to absorb the quintessence from both traditional and foreign poetry. With the "Three Close", New Verse is sure to have a good prospect.


Given the projected growth in IT over the coming decades it is important that the supply of, and demand for, computing services be made as environmentally friendly as possible. One of the key technologies for achieving this will undoubtedly be cloud computing which opens up many new opportunities for streamlining the way computing services are delivered and used. Several research projects have therefore recently started to examine ways of improving the efficiency of cloud computing infrastructures and of understanding the energy efficiency of computing algorithms. However, to date these have mainly focused on increasing the efficiency of cloud computing services at the relatively low "platform" and "infrastructure" levels of abstraction at which they are typically offered today. In this paper we argue that to maximize the environmental benefits of cloud computing, both from the demand as well as the supply point of view, it is necessary to raise the level of abstraction at which cloud services are delivered and consumed. To this end, we introduce the vision of "Modelling as a Service (MaaS)" and explain how it provides an essential foundation for reducing the environmental impact of computing services.


The purpose of this paper is to understand the degree of fragmentation of low-carbon technology institutions by examining different functions of existing institutions to remove barriers to technology development. In order to understand the functions of existing institutions, we first identify barriers of technology development for making low-carbon society in the world, with particular consideration to Asia. We do this by extensive literature review on low-carbon technology, technology innovation as well as insights from the result of case studies. After identifying barriers, we then analyze institutional characteristics of the existing institutions working on low-carbon technology, by looking into their main purposes and actor configurations and by investigating whether and how each institution is working to overcome identified barriers to technology development. Through this analysis, we identify the directions we should follow in order to make more cooperative fragmentation regime in low-carbon technology. We argue that low-carbon technology governance may be best served through a fragmentation of governance architecture, but coordinated by a hub that is capable of quickly accessing usable information and transmitting it to the appropriate institutional nodes in the network.


Abstract A popular approach to model galaxies is Schwarzschild's method. For this method, a grid of sample orbits of stars in an external potential is calculated, and a model for the stellar system is obtained through attributing specific weights to the orbits in a superposition of them. The models created with Schwarzschild's method can fit many observed properties of the modeled stellar system with high precision. However, systems that are stationary as Schwarzschild models may therefore exhibit a strong time evolution if they are translated into more realistic self-gravitating models. The issue is highlighted with the Galactic center as an example.


This work is intended to evaluate a cavitation model based on the complete Rayleigh–Plesset (RP) equation for use in squeeze film damper calculations. The RP equation governs the variation in the radius of the cavitation bubbles at rest, surrounded by an infinite incompressible fluid and subjected to an external pressure. This equation is obtained from the momentum equation and it takes into account the ensemble of the phenomena related to the dynamics of the bubbles (surface tension, damping, and inertia). All the terms in the RP equation will be taken into account in the present work plus a dilatation viscosity introduced by Someya in 2003. Numerical results will be compared with experimental data obtained by Adiletta and Pietra in 2006. The results underline the influence of the effects contained in the RP equation on the pressure field.


Purpose To investigate environmental factors associated with corneal morphologic changes. Methods A cross-sectional study was conducted, which enrolled adults of the Han ethnicity aged 18 to 44 years from 20 cities. The cornea-related morphology was measured using an ocular anterior segment analysis system. The geographic indexes of each city and meteorological indexes of daily city-level data from the past 40 years (1980–2019) were obtained. Correlation analyses at the city level and multilevel model analyses at the eye level were performed. Results In total, 114,067 eyes were used for analysis. In the correlation analyses at the city level, the corneal thickness was positively correlated with the mean values of precipitation (highest r [correlation coefficient]: >0.700), temperature, and relative humidity (RH), as well as the amount of annual variation in precipitation (r: 0.548 to 0.721), and negatively correlated with the mean daily difference in the temperature (DIF T), duration of sunshine, and variance in RH (r: −0.694 to 0.495). In contrast, the anterior chamber (AC) volume was negatively correlated with the mean values of precipitation, temperature, RH, and the amount of annual variation in precipitation (r: −0.672 to −0.448), and positively associated with the mean DIF T (r = 0.570) and variance in temperature (r = 0.507). In total 19,988 eyes were analyzed at the eye level. After adjusting for age, precipitation was the major explanatory factor among the environmental factors for the variability in corneal thickness and AC volume. Conclusions Individuals who were raised in warm and wet environments had thicker corneas and smaller AC volumes than those from cold and dry ambient environments. Our findings demonstrate the role of local environmental factors in corneal-related morphology.


C/C-SiC braking composites were fabricated by warm compressed in-situ reacted process(WC-ISR) with short carbon fibers,graphite powder,Si powder and resin.The compressive properties and fracture mechanism of C/C-SiC braking composites were investigated.Rules about the compressive properties and fracture mechanism of the C/C-SiC composites were ascertained.The results show that the value of vertical compressive strength can reach 118.2 MPa,whose destruction belongs to toughness fraction mechanism by shear stress and is mostly destroyed on the cross.As for the parallel compressive strength,it's value can reach 86.9 MPa,whose destruction belongs to brittleness fracture mechanism and is destroyed by multilayer complex split.The compressive properties increase along with the increase of adding carbon fiber and SiC matrix separately,and carbon fiber carries more weight.However,the more the carbon matrix,the lower the compressive properties.


The Engineering Department at Cedarville University has been making great efforts in helping female engineering students succeed. With no outside funds or support, we designed a self-supporting program. Targeting the high drop-out rate during the freshman year, this mentoring program starts each semester with the new female engineering student orientation. From there, these new students are asked to form horizontal support teams among them. Then upper class female students form vertical mentoring teams with the newest students. Diverse activities are organized to help all the female students meet, communicate and encourage each other. This paper discuss how our mentoring program provides support, what kinds of activities we use to help female students build self-confidence, and our plans for expansion in the coming year. Through this self-supporting mentoring program, initial accomplishment has been seen through female students study and 55% increase in retention rate

Naturally occurring granular flows like landslides often have a gas‐like rapidly moving layer immediately adjacent to a slower quasistatic layer. Determining the nature of coupling between these regimes is critical to capturing flow behavior. Using image analysis and a rheometer, we measure dilation, acoustic energy, and velocity profiles for quartz sand sheared in a geometry that imposes multiple flow regimes at once. We show that acoustic energy resulting from grain collisions in the fastest part of flow causes (a) weakening and compaction of the transitional regime layer between quasistatic and fast flow and (b) increasing slow flow via reduced friction. Thus, the volume of the entire shear zone is governed by competing effects of dilation near the boundary and compaction in the more distant transitional layer. This understanding of the partition of volume change across the shear layer can guide models of natural shear zones and interpretation of deposits.


A slot-fed rectangular dielectric resonator antenna (DRA) with a small ground plane is investigated. By combining the radiation patterns of different resonant modes, a uniform hemispherical radiation pattern can be obtained without requiring any other element. The difference between the maximum and minimum gains is less than 3 dB in the upper half space, and moreover, the front to back ratio is as high as 30 dB.


This paper presents a control design methodology that begins to address high penetration of renewable energy sources into networked AC microgrid systems. To bring about high performing microgrid systems that contain large amounts of stochastic sources and loads is a major goal for the future of electric power systems. Alternative methods for controlling and analyzing AC microgrid systems will provide understanding into tradeoffs that can be made during the design phase. This paper utilizes a control design methodology, based on Hamiltonian Surface Shaping and Power Flow Control (HSSPFC) [1] that regulates renewable energy sources, loads and identifies energy storage requirements for an AC microgrid system. Both static and dynamic stability conditions are derived for the AC microgrid system. Numerical simulations are performed to demonstrate stability and performance. Two scenarios are considered; i) simple random stochastic renewable source and load AC Microgrid example and ii) a random variable pulse load application for Navy ship AC microgrid systems.


The three-sub-lattice approximation model calculations of the energies and magnetic parameters (Curie temperature and mean magnetic moment) were used.  The distributions of atomic species between different model sub-lattices and the thermodynamic properties depending on the s Fe-V alloy compositions at T=0K were evaluated by solving the set of equations at T=0K obtained by minimizing the functional DG with respect to the independent configuration degrees of freedom. The comparison of the calculated data on the structural properties of s-phases in Fe- (Cr, V) systems depending on composition and temperature was conducted. The consistency of the input data and the calculation results for the thermodynamic properties is obtained, namely, the dependence of the enthalpy of mixing of the s –phase of the Fe-V system on the composition relatively of the BCC phases of pure Fe and V. The input data was used to find the initial values of the model parameters. The consistency of these data proves the correctness of the found energy parameters of the model.


Abstract Future high-accuracy space astrometry missions, such as Gaia and SIM, will need a time-tagging of observations consistent with General Relativity nowadays used as standard background for global data processing scheme. In this work, we are focusing on the realization of the onboard time scale. The onboard clock, being not ideal and consequently tainted with systematic biases, has to be carefully calibrated to the ideal relativistic proper time of the satellite. We present here a modeling of this essential step to provide a reliable relation between the onboard time and TCB, a time scale suitable for global data processing.


Recently, SimRank and its variants have attracted a growing interest in the areas of data mining and information retrieval [9]. The philosophy behind SimRank is that two objects are similar if they are referenced by similar objects [3]. Based on this philosophy, the similarity score between a pair of nodes in a graph is iteratively (i.e., recursively) computed as the average of similarity scores among all possible pairs of nodes referencing them. We use the notion of pairwise normalization paradigm (PNP) for this computation manner. SimRank has been successfully applied in different applications such as citation analysis [6] and vertex join query [10].


: Hydro-kinetic turbines operate by using the kinetic energy of the water current in order to produce electric power. The kinetic energy is easily accessible on most rivers, triggering an increasing interest for such devices. Unfortunately, the low power density represents an important barrier to large-scale commercialization. Theoretical Betz law limits the extracted power coefficient to 0.59, but the real on site maximum values range from 0.4 to 0.45. However, a shroud placed around the rotor increases the power output by concentrating the flow from a larger surface and locally increasing the velocity. Thus, the design of the rotor blades is a very complex process due to the fact that the performance of these turbines depends on various parameters like number of blades, tip speed ratio, air foil type, blade pitch, chord length and twist angle along the blade. The paper aims to maximize the performance of a horizontal axis hydrokinetic turbine by assessing the blade chord length influence on the efficiency of such a turbine. The blade chord length and twist angle are firstly calculated, and then validated using Qblade software application. The computations and simulations are performed for a rotor provided with available data from previous tests achieved on site.

Abstract Efficient isolation of genetically modified cells that are phenotypically indistinguishable from the unmodified cells remains a major technical barrier for the broader utilization of CRISPR/Cas9. Here, we report a novel enrichment approach to select the genome engineered cells by co-targeting a genomically integrated GFP gene along with the endogenous gene of interest (GOI). Using this co-targeting approach, multiple genomic loci were successfully targeted in chicken (DF1) and quail (CEC-32) fibroblast cell lines by transient transfection of Cas9 and guide RNAs (gRNAs). Clonal isolation of co-targeted DF1 cells showed 75% of cell clones had deletion of GFP and biallelic deletion of the GOI. To assess the utility of this approach to generate genome modified animals, we tested it on chicken primordial germ cells (PGCs) expressing GFP by co-targeting with gRNAs against GFP and endogenous ovomucoid (OVM) gene. PGCs enriched for loss of GFP and confirmed for OVM deletion, derived by co-targeting, were injected into Hamburger and Hamilton stage 14–15 chicken embryos, and their ability to migrate to the genital ridge was confirmed. This simple, efficient enrichment approach could easily be applied to the creation of knock-out or edited cell lines or animals.

This paper introduces world largest wave energy project being developed in Wales and based on one of the leading wave energy technologies. The background for the development of wave energy, the total resource ands its distribution around the world is described. In contrast to wind energy turbines a large number of fundamentally different technologies are utilised to harvest wave energy. The Wave Dragon belongs to the wave overtopping class of converters and the paper describes the fundamentals and the technical solutions used in this wave energy converter. An offshore floating WEC like the Wave Dragon has to be scaled in accordance with the wave climate at the deployment site, which makes the Welch demonstrator device the worlds largest WEC so far with a total width of 300 meters. The project budget, the construction methods and the deployment site are also given.


ABSTRACT: We hypothesized that during chick embryo cardiac development, cycle length decrease (heart rate increase) may be associated with developmental changes in the ventricular relaxation rate constant, τ, which can be estimated from ventricular pressure decrease by the function P(t) = Poe−1/τ, where Po = pressure at the time of minimum time derivative of ventricular pressure and t = time. Natural logarithm conversion results in a linear relation between In P(t) and t with slope of −1/τ. We determined τ in Hamburger-Hamilton stage 17–27 (d 3–5) embryos (n = 35) at intrinsic cycle length and in stage 24 embryos (n = 5) during cardiac cycle length perturbations with the hot-cold probe technique. Regression analysis of In P(t) from the minimum dP/dt until t as 30 ms was used to estimate r. Intrinsic cycle length decreased during development from stage 17 to 27 and τ decreased linearly as cycle length decreased (r = 039, p < 0.005). Thus, during early development, both τ and cycle length decrease (relaxation rate and heart rate increase). In stage 24 embryos, cycle length perturbation yielded a nonlinear cycle length-dependent relation with τ, with a plateau at cycle lengths less than intrinsic, i.e. τ decreased with cycle length decrease to intrinsic cycle length, then τ plateaued with further cycle length decrease. These findings demonstrate that ventricular relaxation rate is both maturation and cycle length dependent. The plateau effect of the τ-cycle length relationship may be due to developmental limitations of the calcium transport system.


We present experimental results of thrust produced by a robotic propulsor, the design of which is inspired by the ribbon fin of the South American black ghost knifefish (Apteronotus albifrons). This remarkably nimble fish moves by oscillating its ribbon fin rays out of phase and thereby passing a traveling wave along the fin's length. Combinations of thrust from the ribbon fin and body rolls produced by the two pectoral fins enable the black ghost to swim in nearly any direction without bending its body. The fish's agile locomotor system is tightly integrated with its omnidirectional, active sensing system. The robotic ribbon fin has eight individually actuated metal rays which are linked by a thin latex sheet. The experimental results demonstrate the effect of varying the propulsive wave's frequency, amplitude and length on the robotic fin's thrust production. We found that thrust production peaks at particular combinations of the three variables and that the fin could produce steady forward thrust, despite the relatively small number of rays. The robotic ribbon fin has potential application as a propulsor for future underwater vehicles, in addition to being a valuable scientific instrument in understanding the swimming mechanics of the black ghost and similar fish


Purpose: The purpose of this article is to review the evidence surrounding similarities and differences in motor development in children of Asian and European ethnic backgrounds to ensure the appropriateness of mixed ethnicity normative comparison data. Summary of key points: A review of published studies indicates variability in rate and possibly sequence of motor development in children of European and Asian origins. Statement of conclusions and recommendations for clinical practice: Assessment tools used to discriminate motor development in children of different ethnic backgrounds should be interpreted with caution until there is sufficient information regarding the appropriateness of comparisons among children of different ethnic origins.


Background: Dipeptidyl peptidase-4 inhibitors (DPP-4i) interact with sulfonylureas (SU) to increase their risk of hypoglycemia. However, it is unclear whether this risk varies with the pharmacologic properties of DPP-4i. Thus, we compared the risk of severe hypoglycemia between concomitant use of SU and peptidomimetic DPP-4i (vildagliptin, saxagliptin) vs. non-peptidomimetic DPP-4i (sitagliptin, linagliptin, alogliptin) in patients with type 2 diabetes.
 Methods: We conducted a retrospective cohort study using the UK's Clinical Practice Research Datalink linked to hospitalization and vital statistics data of patients with type 2 diabetes initiating SU between 20 and 2020. Time-dependent Cox models estimated hazard ratios (HR) with 95% confidence intervals (CI) of severe hypoglycemia associated with current concomitant use of SU and peptidomimetic DPP-4i compared to current concomitant use of SU and non-peptidomimetic DPP-4i, adjusted for baseline confounders. Secondary analyses stratified by age (<65 vs. ≥65 years) and sex.
 Results: Our cohort included 196,138 SU initiators. The crude incidence rate of severe hypoglycemia was 7.2 per 1000/year. Compared to concomitant use of SU and non-peptidomimetic DPP-4i, concomitant use of SU and peptidomimetic DPP-4i was not associated with the risk of severe hypoglycemia (HR, 0.96; 95% CI, 0.76-1.22) . In female patients, concomitant use of SU and peptidomimetic DPP-4i was associated with a trend towards an increased risk (HR, 1.32; 95% CI, 0.97-1.81) ; in male patients, there was an association with a decreased risk (HR, 0.69; 95% CI, 0.48-0.99) . Age did not modify the association.
 Conclusion: Our population-based study showed no increased risk of severe hypoglycemia with concomitant use of SU and peptidomimetic DPP-4i compared to concomitant use of SU and non-peptidomimetic DPP-4i. Further research is needed to corroborate the observed effect modification by sex.

Some of the sources include Hebrew Bible/Old Testament, Apocrypha, Pseudepigrapha, New Testament, Dead Sea Scrolls, and Greek and Latin Works. The book sets out to construct some of the Jewish and Greco-Roman patterns of thought which were initially utilised to express the meaning of the death of Christ.Keywords: Dead Sea Scrolls; Pseudepigrapha


The booklet, grown out of lectures dating back to 1951, deals with prepositional logic in a way which is inspired mainly by Quine's XV 203 and Strawson's XVIII 273. Its first pages contain little that is new relative to these books. Later on, however, an interesting method for a systematic study of the interrelations between the truthfunctional connectives is introduced by which, among other results, the problem of finding complete bases for these connectives is elegantly solved. This method can also be used for reducing any truth-functional formula to a simplified disjunctive form called by the author its d-form, in a way which is quite different from the one employed, e.g., in Quine's XVIII 280. Finally a one-place and a two-place functor over propositional formulas are introduced, which have the properties of absolute and relative probability measures. In these terms, the notions of relevance, evidence, and consequence are defined in a way which seems to be sufficiently adequate for their restricted field of applicability. The author's approach to inductive logic through these functors does not look very promising. In the first paper, a distinction is drawn between language and discourse, approximately along the type-token axis. The author goes on to see in the analysis of the various kinds of discourse the main task of modern analytic philosophy, and more specifically sees as one sub-task the improvement of the meta-discourse of the scientists. This improvement should be achieved through the designing of wholesale models rather than through the term-wise analysis of meta-terms. The author himself discusses one such model, the molecular closure over a set of totally independent atomic propositions, which he calls a W(ittgenstein)-model. This model is further studied in the second paper. Logical probability measures in this model are what Carnap and the reviewer called, in X I X 230, £)-functions. As such they are not suitable for many situations where inductive reasoning is of importance. The author goes on to explicate the notion of information content in a way that is different from both measures introduced in X I X 230. (Whereas for cont, the "first explicatum" in XIX 230, cont(~i) = 1 — cont(i) holds, and for inf, the "second explicatum," inf(~t) = inf(t) — log2(2<) — 1) holds, the author requires for his C that C(—i) = l/C(i).) The introduction of the epistemological notion "is known" into this discussion seems to be perfectly gratuitous, as is the functor PE(H), interpreted as the probability of H when E "is known" and defined as PE(H) — P(H) + Rel(#, E), where Rel(H, E) was defined a few lines before as P(H, E) P{H), so that clearly PB(H) = P(H, E), showing that the "epistemological" notion is no different from the "relative" (or conditional) one. Strangely enough, this seems to have been missed by the author. The attempted explication of "essentially" positive properties is essentially circular and will not impress those thinkers who see here a serious ontological problem (which the reviewer does not). Other parts of the papers are rather obscure and sketchy. The author does not seem to have read X I X 230 and related papers, while writing his papers. As a curiosity, it should be added that the linguist Z. S. Harris published in 1952 a paper called Discourse analysis in Language, vol. 28 (1952), pp. 1-30, in which he laid the foundation for a new branch of descriptive linguistics, viz. one in which units longer than sentences, whole "discourses," are studied.


enter sperm cells and oocytes. More recently, the proviral DNA of bovine immunodeficiency virus was detected in association with frozen bull semen, but the transmission ofthe virus to oocytes by infected sperm during fertilisation was not investigated (Nash and others 1995). Since the swim up procedure generates a practically clean motile sperm fraction which is free of other cells, it is conceivable that BLV becomes associated with some sperm cells and is carried through the zp into oocytes during fertilisation which most likely were resistant to the viral infection. Since all IVF embryos tested negative, it can be speculated that the sensitivity of the PCR was insufficient to detect the proviral DNA associated with a single sperm cell introduced into embryos during fertilisation. It is also possible that the proviral DNA was adversely affected by the incubation conditions of embryos during the eight days after fertilisation. Although in this study, all embryos tested negative for proviral DNA, it is advisable for IVF practitioners to use semen from bulls free of BLV. Also, in view of the fact that as little as 1 [d of BLV-infected blood can be sufficient to transmit the disease (Evermann and others 1986), efforts should be made to limit the amount of aspirated blood associated with the follicular fluid during oocyte retrieval, and special attention should be paid when washing embryos (Stringfellow and Seidel 1998). In conclusion, these results indicate that IVF embryos generated in the presence of BLV do not appear to be associated with infectious BLV, as previously demonstrated for in vivo produced embryos. However, experiments involving the transfer of IVF embryos are needed to verify these studies. Further studies on the interaction of BLV with sperm cells also appear to be warranted.


Underwater image enhancement techniques are essential for improving the visual quality of images captured in underwater environments. These techniques can help researchers and scientists extract useful information from underwater images, aid in environmental monitoring, and support various underwater applications such as underwater exploration, oceanography, and marine biology.Underwater image enhancement technique involves two categories-pre-processing techniques and post processing techniques.


Beans are one of the most sown legumes on the planet due mainly to their flavor, nutrients and proteins that contribute to the daily diet of the human being.
Due to the scarce information on the agronomic behavior by ender this investigation has like general objective to determine the agronomic behavior and yield of five varieties of beans under condition of humidity to capacity of field, and the preferences in the market and final consumer; It should be noted that the varieties of beans were subjected to irrigation applications and without irrigation. In the study of the variables, no statistical differences were found between the irrigated and non-irrigated plots, except for the tumbe variety, which obtained the highest yield in the irrigation treatment than in the non-irrigated treatment, on the other hand, the bean varieties where applied irrigation obtained higher yield values in comparison to treatments where no irrigation was applied with the exception of the variety of beans Patience that registered the highest average without the application of irrigation, as far as the agronomic development of the bean plants was mostly efficient in where irrigation was applied obtaining higher plants or with greater number of pods per plant at harvest. When the economic analysis was carried out, it was obtained that the variety of Tumbe beans in irrigation application obtained the highest profitability with 87.60% reaching a net profit of $ 937.65. The most common bean is forty-year-old bean with 36% followed by pigeon's leg with 28% and the least known bean is patience with 8%, the most consumed bean is 40 year old with 54% followed by pigeon leg variety with 35%, and the least consumed is patience with 8%, respondents indicated that the consumption of beans is mostly due to the flavor, highlighting this inclination for the forty-year-old frijol 64% followed by the pigeon's leg 39 %, the custom was another option mostly chosen when consuming beans.

Key words: Varieties, irrigation, Tumbe beans, beans Patience


Abstract: P0 glycoprotein, the major protein of PNS myelin, contains approximately 1 mol of covalently bound long‐chain fatty acids. To determine the chemical nature of the fatty acid‐protein linkage, P0 was labeled in rat sciatic nerve slices with [3H]palmitic acid and subsequently treated with various reagents. The protein‐bound palmi‐tate was released by incubation with the reducing agents dithiothreitol and 2‐mercaptoethanol, and with 1M hydrox‐ylamine at pH 7.5. In addition, P0 was deacylated by treatment with 10 mM NaBH4 with the concomitant production of [3H]hexadecanol, indicating that the fatty acid is bound in a thioester linkage. This conclusion was supported further by the fact that deacylation with hydroxylamine generated free thiol groups, which were titrated with [14C]‐iodoacetamide. To identify the cysteine residue involved in the thioester linkage, [14C]carboxyamidomethylated P0was digested with trypsin and the resulting peptides analyzed by reversed‐phase HPLC. Identification of the radioactive protein fragments by amino acid analysis and amino‐terminal peptide sequencing revealed that Cys153 in rat P0 glycoprotein is the acylation site. The acylated cysteine is located at the junction of the putative transmem‐brane and cytoplasmic domains. This residue is also present in the P0 glycoprotein of other species, including human, bovine, mice, and chicken.

The "spectrum-slicing" technique employing incoherent light has been shown to be a highly practical, cheap and hence very attractive proposal for future all-optical networks. In this study, the use of Semiconductor Optical Amplifier (SOA) gain saturation for intensity noise reduction of incoherent light is studied with a view to obtaining the optimum SOA injection current and input power conditions to achieve the best possible intensity noise reduction-in terms of OSNR, BER, noise power and Q-factor. The results reported herein give designers knowledge of the best SOA operating conditions to enhance overall system performance, while still obtaining signal gain from the SOA.


The subjects of commercial bribery can be divided into several groups,such as the person who gives money or property to others and the person who accepts another person's money or property,state functionary person and non-state functionary person,the person and the unit.Criminal responsibility is borne according to the subject status and authorized strength.As to the same action,the state functionary person and state body would bear much more heavy criminal responsibility than those who are not state functionary person or state body.To those which do not work in state-owned units,even if they accept another person's much money or property,they will not be regarded as crimes,which is extremely unfavorable to punish commercial crime participated by persons in the units.


Social trust is one of the foundations for social order in society. Trust in any organization is affected by various factors such as customer satisfaction, service quality, staff skill and taking into account the customer orientation and service receivers' satisfaction principles. This research seeks to study the sociological study of social trust of the insured population of social security organization. The theoretical framework of this research is based on the Zetomka and Parasuraman theory and the research method is a survey and the research tool is questionnaires used for 364 of the insured population in West Tehran Social Security Branches selected through multistage cluster sampling. Based on the results, there is a positive and significant relationship between social trust and customer satisfaction (r = 0.70), service quality (r = 0.64), organizational performance (r = 0.73), and staff skill (r = 0.69) variables. Also, there is a relationship between customer satisfaction and organizational performance (0.85 = value), service quality (0.74 = value), and staff skills (0.82 = value).


Introduction The Zambezi Society is a Zimbabwe-based nongovernmental membership organization devoted to conserving the biodiversity and wilderness values of the Zambezi River in central-southern Africa, and to encouraging people to find ways of benefiting from the river's resources without destroying them. During the latter half of the 1990s, the society began to receive numerous complaints and concerns from various sources, implying that tourism was having a negative impact on the wilderness values of the Zambezi River. The reports were wide-ranging, including unchecked commercialization, ad hoc development, tree cutting, border violations, unauthorized road and camp building, noise pollution, littering and abuse of camping sites, and illicit tour and guide activities. The overall concern was that the special "wilderness value" of the Zambezi River was being eroded by inappropriate visitor behavior and tourism development. In order to provide visitor input, the society embarked in 1998 on a survey project aimed at reporting visitors' perceptions about wilderness values and importance in the Zambezi context as well as providing a visitor-based definition of the term wilderness.


It is essential for state-owned hospitals to construct a job evaluation system that not only highlights contribution and efficiency but also avoids evaluation system which is profit-oriented.Human resources theory and management science are applied in the construction of this evaluation system in states-owned hospitals,producing an set of integrated and feasible balanced scorecard indicators in job performance evaluation based on job ranking,service quality and working efficiency.Bi-level programming is applied in the connection of line sectors and functional sectors while analytic hierarchy process is introduced in weighing indicators.


Typical Wannier-function downfolding starts with a mean-field or density functional set of bands to construct the Wannier functions. Here we carry out a controlled approach, using DMRG-computed natural orbital bands, to downfold the three-band Hubbard model to an effective single band model. A sharp drop-off in the natural orbital occupancy at the edge of the first band provides a clear justification for a single-band model. Constructing Wannier functions from the first band, we compute all possible two-particle terms and retain those with significant magnitude. The resulting single-band model includes two-site density-assisted hopping terms with $t_n \sim 0.6 t$. These terms lead to a reduction of the ratio $U/t_{\rm eff}$, and are important in capturing the doping-asymmetric carrier mobility, as well as in enhancing the pairing in a single-band model for the hole-doped cuprates.


On 21 January 1961, the Santa Maria, a Portuguese cruise ship with over 600 passengers and a crew of 350, entered Willemsted, Curaçao island in the Caribbean so the tourists could do what tourists were supposed to do – spend money on the local economy. One of the passengers was not feeling well and requested a Protestant minister who could speak English be summoned to provide counseling and prayer. A quick search of the phone book led to a call, and the Seventh-day Adventist pastor, with his four-year-old son in tow, boarded the ship for several hours, during which the young boy played with members of the crew until the announcement was made to prepare for departure. Twenty-four hours later, the Santa Maria was taken over by the Iberian Revolutionary Directorate of Freedom (DRIL), one of several insurgent groups seeking the independence of all Portuguese colonial holdings in Africa and Asia. The ship and its hijacked passengers became a political crisis of international proportions, as Portuguese President Antonio Salazar requested aid from his NATO allies. These promptly identified the negative aspects of all possible outcomes, including support for an unpopular dictatorship, for insurgent forces, or the specter of over 900 dead tourists and crewmembers. In the end, a solution was arranged that satisfied no one except Galvão, the DRIL leader, who unloaded the ship in Recife, Brazil and promptly requested asylum in that country. The Santa Maria was returned to Salazar, who complained of not getting his hands on the hijackers. I seriously doubt the publisher who mailed a copy of Cann's book for review knew I had any connection to the events of that day. The book did trigger memories, however, as I distinctly remember being on the ship when the 'All Aboard' call was made, fearing that somehow my father and I would not make it off in time. Needless to say we were not on board when the ship left Curaçao and thus were spared the experience of those who remained on board. This is an impressive book, as Cann does a major favor to those few of us who like all things riverine by filling the volume with much more data than the title promises, and does so without overwhelming us with material. There is a logical flow of data that eases readers from the general international overview ('A New Phase of the Cold War') to the national politics of post-World War II


In order to study some properties of co-transformation,five different genes were introduced into embryogenic calluses of maize by particle bombardment.The DNAs used for co-transformation were p35sGFP and pActGus(two types of scorable mark gene),pUbiLuc(luciferase enzyme reporter gene),p35sPatPIV4(a selectable herbicide-resistance gene) and pAH2.Total 34 surviving independent transplants were obtained from B1,B2,B3 and B4 involving 73,46,80 and 109 bombarded embryos.The frequencies of B1,B2,B3 and B4 were 30.14%,17.39%,1.25% and 2.75%,respectively.One transplant generally was obtained from one event of bombarded embryo.The possibility was that more than three transplants might be obtained from the same event of bombarded embryo.There was 70% chance that three and four genes could be integrated into the genomes of the transformants for at least one copy.The chance of all five genes integrated into the genomes of the transformants was very low.The size of the transgenes and the quality of the DNAs might affect the clone frequency.The expression frequency of transgenes integrated to the genomic DNA of maize plants reached more than 50%.The non-expressional transgenes integrated to the genomic DNA might have the presence of gene silence phenomena in the transformants obtained in this study.


BACKGROUND:Raw and roasted nuts are one of the most popular snacks consumed in Iran but mishandling and poor storage conditions and practices may lead to promote the growth of microorganisms and foodborne intoxications and infections. OBJECTIVES:The purpose of this study was to investigate the microbial quality of raw and roasted (salted and unsalt- ed) nuts, distributed in commercial markets in Mazandaran province, Iran. METHODS:The moisture content, total colony counts, total coliform, fecal coliform, Staphylococcusaureus, and fungal contamination were evaluated according to procedures of Iran national standards. RESULTS: The moisture content of raw and roasted hazelnut, pistachio, almond, and cashew nut samples were above the standard limits. The moisture content of the raw peanuts was within the standard approved limit (maximum 9%). But the moisture content of the roasted peanut was higher than the permissible limit of 5%. For yeasts and moulds, except for all almond samples and 56% of cashew nut samples, all products tended to be loaded with unsatisfactory limits. The total viable count was within the standard limits in hazelnut, almond, and cashew nut samples (less than 4log cfu/gr). Satisfactory limits of coliforms (lower than 1log cfu/gr) were observed in all almond samples, 91.6% of hazelnut, and 16.7% of pistachio samples. No fecal coliforms were detected in samples. S.aureus contamination was observed in 6.5% of hazelnut, 8% of almond, 25% of cashew nut, and 33% of peanut samples. CONCLUSIONS: According to the findings, almond and hazelnut showed the least, and pistachio and peanut samples showed the highest microbial contamination.


In the research field of the intelligent transportation system (ITS) and the roving robot, the driver-support system auto-recognizing road signs and the robot control system auto-recognizing behavior-indication signs are variously suggested. Both systems use the dynamic image processing to acquire features such as the shape and design of signs. Artificial signs valid for the machine vision are sometimes used for these researches. However, in this study, the general road signs adopted in public roads are used, because machines such as robots and vehicles are supposed to live together in real environments. In this paper, nine kinds of signs one third in size such as "STOP," "NO ENTRY" and "NO PASSAGE" are prepared, and then some experiments were carried out to recognize these signs under various kinds of measurement condition.

A disposable urinating funnel for females comprises a thin, paper-like sheet which is folded in half to form two overlapping sections whose free edges are connected together and are tapered toward the fold line to form a funnel-like shape. The upper edges of the funnel-shape are curved to cover a female vaginal area, and the opposite, bottom edges form a spout-like portion. Score lines are formed midway between the fold line and connected side edges in each of the sections and extend upwardly from the bottom of the spout-forming portion toward the upper end of the funnel-like shape. Manually squeezing the fold line and connected side edges toward each other causes the otherwise flat funnel-like shape to open, by bowing the sections apart along the score lines. In addition, the tapered, connected-together edges are cut along a shallow curve which permits the funnel to be used with the fold line forwardly or rearwardly for selectively directing the flow of liquid through it.


Long-range interatomic distance restraints are critical for the determination of molecular structures by NMR spectroscopy, both in solution and in the solid state. Fluorine is a powerful NMR probe in a wide variety of contexts, owing to its favorable magnetic properties, ease of incorporation into biological molecules, and ubiquitous use in synthetic organic molecules designed for diverse applications. Due to the large gyromagnetic ratio of the 100% naturally abundant 19F isotope, interfluorine distances as long as 20 Å are accessible in magic angle spinning (MAS) dipolar recoupling experiments. Herein, we present an approach for the determination of accurate interfluorine distances in multi-spin systems, using the finite pulse RFDR (fpRFDR) at high MAS frequencies of 40–60 kHz. We use a series of crystalline "molecular ruler" solids, difluorobenzoic acids and 7F-L-tryptophan, for which the intraand intermolecular interfluorine distances are known. We describe the optimal experimental conditions for accurate distance determinations, including the choice of a phase cycle, the relative advantages of selective inversion 1D vs. 2D correlation experiments, and the appropriate numerical simulation protocols. A best strategy for the analysis of RFDR exchange curves in organic solids with extended spin interaction networks is presented, which, even in the absence of crystal structures, can be potentially incorporated into NMR structure determination.

Abstract. The Bohai Sea (BHS) is a semi-closed marginal sea impacted by one
of the most populated areas of China. The supply of nutrients, markedly that
of reactive nitrogen, via fluvial and atmospheric transport has strongly
increased in parallel with the growing population. Therefore, it is crucial
to quantify the reactive nitrogen input to the BHS and understand the
processes and determine the quantities of nitrogen eliminated in and
exported from the BHS. The nitrogen budget and in particular the internal
sources and sinks of nitrate were constrained by using a mass-based and dual
stable isotope approach based on δ15N and δ18O of
nitrate (NO3-). Samples of water,
suspended matter, and sediments were taken in the BHS in spring (March and
April) and summer (July and August) 2018. The Yellow River (YR) was sampled
in May and July to November, and Daliao River, Hai River, Luan River, and
Xiaoqing River were sampled in November of 2018. In addition to nutrient,
particulate organic carbon, and nitrogen concentrations, the dual isotopes of
nitrate (δ15N and δ18O), δ15N of
suspended matters, and sediments were determined. Based on the available mass
fluxes and isotope data an updated nitrogen budget is proposed. Compared to
previous estimates, it is more complete and includes the impact of interior
cycling (nitrification) on the nitrate pool. The main nitrate sources are
rivers contributing 19.2 %–25.6 % and the combined terrestrial runoff
(including submarine fresh groundwater discharge of nitrate) accounting for
27.8 %–37.1 % of the nitrate input to the BHS, while atmospheric input
contributes 6.9 %–22.2 % to total nitrate. An unusually active interior
nitrogen cycling contributes 40.7 %–65.3 % to total nitrate via
nitrification. Nitrogen is mainly trapped in the BHS and mainly removed by
sedimentation (70.4 %–77.8 %), and only very little is exported to the
Yellow Sea (YS) (only 1.8 %–2.4 %). At present denitrification is active
in the sediments and removes 20.4 %–27.2 % of nitrate from the pool.
However, a further eutrophication of the BHS could induce water column
hypoxia and denitrification, as is increasingly observed in other marginal
seas and seasonally off river mouths.


Training organizations in the public sector, on the other hand, have a mission to arrange training programs for human resource development at all levels. As a result, the training program's goal is to increase trainees' capacity in terms of skill, knowledge, and work behavior (attitude) so that they can offer better service to citizens.The Bangladesh Public Administration Training Centre (BPATC) and Bangladesh Public Service Administration Academy (BCSAA) are responsible for providing civil officials with training. The government has made training and development the highest priority, investing much in this domain. Motivation to the transfer of training has many folds; therefore, this study aims to identify the factors for motivation to transfer of training and find out the relationship of influencing factors for motivation to training transfer.The research took a quantitative method. The respondents have worked in the field and have received training from either BPATC or BCSAA or both training organizations. Using standardized questionnaire item scores ranging from "strongly agree" to "strongly disagree," data was collected from respondents.This study employed a purposeful random sampling approach. Because of the COVID-19 pandemic, an online questionnaire (emailing) was circulated to 1800 participants who had received training from BPATC and BCSAA. A total of 307 respondents participated in the study.A model was developed based on research hypotheses. Model and formulated hypotheses were tested by Regression and Coefficient results, some hypotheses are shown positive and significant impact on the transfer of training. The regression model is significant, according to the results. Furthermore, some factors have a positive effect on motivation to transfer training according to Standardize coefficient value and level of significance (p<.05)


This paper describes our system developed for the Social Media Mining for Health (SMM4H) 2022 SocialDisNER task. We used several types of pre-trained language models, which are trained on Spanish biomedical literature or Spanish Tweets. We showed the difference in performance depending on the quality of the tokenization as well as introducing silver standard annotations when training the model. Our model obtained a strict F1 of 80.3% on the test set, which is an improvement of +12.8% F1 (24.6 std) over the average results across all submissions to the SocialDisNER challenge.


Conventional wisdom suggests that managers should bring their full-blown possibility to work. Even though research has demonstrated positive outcomes such as increased job satisfaction, decreased turnover, or increased creativity, the current research depicts a "dark side" of integrating non-work and work identities when it comes to data-driven decision-making. More specifically, three studies and two pretests with 524 experienced marketing managers consistently show that managers' non-work identity deleteriously affects strategic marketing decisions if market research insights clash with a manager's activated identity. We show that this unfavorable effect does not happen if managers clearly distinct between private and work life, and identify the relationship norm between the decision maker and the provider of market insights as a boundary condition. Overall, this research raises the question, whether and particularly when managers should be motivated to bring their "whole selves" to work and when companies may take active steps against such an integration.

Pocket-pads or steps are often used in journal bearing design, allowing improvement of the latter's dynamic behavior. Similar "discontinuous" geometries are used in designing thrust bearing pads. A literature review shows that, to date, only isoviscous and adiabatic studies of such geometries have been performed. The present paper addresses this gap, proposing a complete thermohydrodynamic (THD) steady model, adapted to three-dimensional (3D) discontinuous geometries. The model is applied to the well-known geometry of a slider pocket bearing, operating with an incompressible viscous lubricant. A model based on the generalized Reynolds equation, with concentrated inertia effects, is used to determine the 2D pressure distribution. On this basis, a 3D field of velocities is constructed which, in turn, allows the resolution of the 3D energy equation. Using a variable-size grid improves the accuracy in the discontinuity region, allowing an evaluation of the magnitude of error induced by Reynolds assumptions. The equations are solved using the finite volume method. This ensures good convergence even when a significant reverse flow is present. Heat evacuation through the pad is taken into account by solving the Laplace equation with convective boundary conditions that are realistic. The runner temperature, assumed constant, is determined by imposing a zero value for the global heat flux balance. The constructed model gives the pressure distribution and velocity fields in the fluid, as well as the temperature distribution across the fluid and solid pad. Results show important transversal temperature gradients in the fluid, especially in the areas of minimal film thickness. This further justifies the use of a complete THD model such as the one employed.


lthough she denies it, Sister Elizabeth Davis, a member of the Congregation of the Sisters of Mercy of Newfoundland and Labrador, is becoming a Canadian icon: in education, in healthcare, in leadership development, in social policy and in religious studies, in Canada and abroad. With teaching appointments and participation on many boards and commissions, she leaves a trail of wisdom, quiet successes and vocal fans in her wake. In 2001, she won the Catholic Health Care Association of Canada's Performance Citation Award and the Canadian Healthcare Association's Award for Excellence in Distinguished Service. Those were followed by an Honorary Doctor of Laws from Memorial University of Newfoundland, induction into the Alpha Sigma Nu Honour Society of Jesuit Educational Institutions and an appointment as a Member of the Order of Canada in 2004. Recently, the University of Toronto's Department of Health Policy, Management and Evaluation selected Sister Elizabeth as Leader of the Year for 2006. Ken Tremblay caught up with Sister Elizabeth at St. Augustine's Seminary in Toronto, where she is currently teaching a course titled Introduction to the Old Testament.


This research study examined the dexterity performance of both male and female subjects at ambient temperatures of 35°, 55° and 75°F. Subjects wore typical industrial worker apparel without gloves. Four dexterity measurement methods were used. These were 1) Purdue Pegboard, 2) pencil point tapping, 3) an assembly task, and 4) a fine manipulative task. The subject's performance scores at the various tasks were correlated with the ambient temperature and the hand-skin temperature. Results indicate that females scored better than males on the Purdue Pegboard and a fine manipulative task at all temperatures, while males scored better in pencil point tapping and an assembly task.


We experimentally prove high-speed underwater optical wireless transmission over 2.5 m distance, using different bit rates and modulation schemes. The system uses two low-cost Light Emitting Diodes (LEDs) arrays as optical transmitter and an avalanche photodiode module as receiver. The measurements are taken using an outdoor water tank having 3.3 m diameter, where two waterproof boxes containing the transmitter and the receiver are fixed underwater at the inner borders. We test 6.25 Mbit/s with Manchester coding, 12.5 Mbit/s with NRZ 8b/10b coding and 58 Mbit/s with Discrete Multitone modulation. Bit Error Rate measurements are collected over several hours under typical summer sunlight illumination conditions. In all the experimental conditions we achieve error free transmission.


Mr. Wolfe's interesting, and very persuasive, paper has stimulated me to think again about this problem. As a result, the following possible counterexample to his claim that it is logically impossible to pretend to be awake has now occurred to me. Let us suppose that A is acting as subject in a study of the electrical activity of the brain during sleep. Every night electrodes are applied to his scalp and an electroencephalograph recording of his 'brain waves' is made. An experimenter (B) sits by his bedside and observes the EEG as it is recorded (perhaps in order to be able to note any changes in A's sleeping position, breathing &c. that are associated with variations in the EEG). One morning B shows A a segment of his EEG for the preceding night that indicates that, an hour before he finally woke up, some previously unrecorded form of activity was taking place in A's brain for a period of about half a minute. B asks A if he can recall any experience that might throw light on this. A, for some reason (perhaps he only agreed to act as a subject in the hope of thereby finding some way to discredit B, or electroencephalography) lyingly reports that, although he does not recall any unusual dream experience, he does remember having awakened briefly, but without moving or opening his eyes, at a time that seems to him quite probably to have been about an hour earlier than that at which he finally woke up. However A actually recalls, though he does not tell B about it, a seemingly quite brief, but unusual, dream episode that seems to him to have been part of a dream that he had some while, but not so very long, before waking up. This episode consisted in his dreaming that he was on the roof of an immensely high building and that, after looking over the edge of it for some while, some-

During the past decade, self-disclosure has gained status as a popular antidote to a variety of social and personal problems. Jourard (1964) advo cates a transparent self. Mowrer (1964) thinks we should get together and confess our sins to one another. Rogers (1961) implores us to be congruent. and for Bugental (1965) we must be authentic. In popular language, we are told that the "name of the game" is to "tell it like it is." Ostensibly an alienated generation is impatient with hypocrisy. Several varieties of group experience have become increasingly fashionable. Group efforts to improve communication and to develop sensitivity to the needs and feelings of others are indeed laudable. Unfortunately, the growth of such groups has mushroomed without adequate professional control or disciplined study. In a popular article entitled "Group Therapy: Let the Buyer Beware," Shostrum (1969) forewarns us of highly perilous groups. A few unhappy experiences have demonstrated that the "authenticity game" or if you prefer "psychological strip tease" can be as dangerous as Russian roulette. By no means are all group experiences to be viewed negatively. Some have produced demonstrably beneficial results. In contrast to the social gossip and small talk of everyday life, communication which occurs in sensitivity groups most often is experienced as deeply meaningful. The long term cor relates of analogous modes of relating and communicating have yet, how ever, to be thoroughly examined. It is to such topics that studies in self disclosure may provide some illumination. The purpose of this paper is to bring together a few significant findings from the research on self-disclosure and to consider their implications for group counseling with adolescents.


Previously, we evaluated the importance of the mechanosensitive protein ASIC2 in pressure‐induced constriction (PIC) in middle cerebral arteries in the ASIC2 mouse model. ASIC2 +/+ and −/− mice developed similar PIC (16 ± 2 and 10 ± 3%, respectively at 90 mm Hg). However, surprisingly, ASIC2 +/− mice developed less PIC (4 ± 2%). Since previous reports indicate 1) β and γENaC also mediate PIC and 2) ENaC can interact with ASIC2, the goal of our study was to determine if reductions in mechanosensitive γ and γENaC protein might contribute to loss of PIC in ASIC2 +/− mice. To address this, we used quantitative immunolabeling for ASIC2, βENaC and γENaC in VSMCs from ASIC2 +/+, +/− and −/− mice. Fluorescence intensity (FI) was normalized for α‐actin and background subtracted (Fig. 1).

This report describes the hereditary occurrence of severe laryngomalacia in three of five siblings of a Mexican‐American family. The mother, who experienced respiratory difficulties in the first year of life, may also have been affected. All three affected children required neonatal tracheostomy, and two died of pulmonary complications. Histological studies of tracheal cartilage revealed distinct hypercellularity and histochemical staining abnormalities of the cartilaginous matrix without defects in skeletal cartilage.


The potato tuberworm, Phthorimaea operculella (Zeller) (Lepidoptera: Gelechiidae), is a worldwide pest of solanaceous crops especially devastating to potatoes. In the present study, we investigated the cold hardiness profile of acclimated and non‐acclimated immature and adult stages of a field population of P. operculella. For both acclimated and non‐acclimated individuals mean supercooling point (SCP) did not differ significantly among developmental stages. Unlike supercooling capacity, acclimation at 5 °C for 5 days enhanced the ability to survive at subzero temperatures after a 2‐h exposure. Median lethal temperature (LT50) of all developmental stages (egg, late instar, pupa, and adult) decreased after acclimation, nevertheless only adults displayed a significant difference among acclimated and non‐acclimated individuals concerning their LT50 (−11.1 and −8.3 °C, respectively). Generally, pupae were the most cold‐tolerant developmental stage followed in decreasing order by the eggs and adults, whereas late instars were the least cold tolerant. Non‐freezing injury above the SCP was well‐documented for all developmental stages indicating a pre‐freeze mortality and suggesting that P. operculella is considered to be chill tolerant rather than freeze intolerant. Nevertheless, given its high degree of cold hardiness relative to habitat temperatures, winter mortality of P. operculella due to low temperatures is not likely to occur and pest outbreaks may take place following a mild winter.


Tiivistelmä-Referat-Abstract This thesis analyzes the implicit delivery option in a bond futures contract and its effect on the contract's hedging effectiveness. Bond futures are widely used in hedging of government debt securities. In this thesis, the delivery option arises from the futures seller's right to choose which bond, among several deliverable bonds, will be delivered at the delivery date. To the extent this delivery option has value it should be reflected in a reduced futures price, because the buyer of futures must be compensated for the freedom of choice the seller has in choosing the asset to be delivered. The objective of the study is to price the futures contract and its delivery option in a theoretically consistent framework. In particular, the difference in valuing the option under constant interest rate and under stochastic term structure will be emphasized. Secondly, this paper studies whether the delivery option harms or helps the hedging effectiveness of the futures contract. Also, the effectiveness of the widely used conversion factor hedging method is questioned in the stochastic interest rate environment. The base for modelling the delivery option is the formula generating value for an exchange option. This formula was first introduced by Margrabe (1978) and is an extension of the Black-Scholes solution (1973) to option pricing problem. The delivery option will be modelled in the fixed interest rate environment (Hemler 1990) and under stochastic term structure (Lin and Paxson 1995). The stochastic term structure of interest rates will be represented with a term structure model by Heath, Jarrow and Morton (1992), although only the intuition of the HJM -model will be presented. The result of this paper is that the delivery option has to be included to the futures pricing formula and the theoretical equilibrium price of the futures contract with the delivery option can be obtained on a theoretically consistent basis. Secondly, there were no evidence that the delivery option would significantly harm the hedging effectiveness of the Euro-Bund futures contract. Theoretical drawbacks of the conversion factor hedging method appeared only, when hedging short-term bonds with the 10-year Bund futures con-tract.

The events of September 11th have triggered a national reexamination of the security of airlines, drinking water supplies, nuclear plants, and other areas. Policymakers to date have inadequately addressed the public health threat posed by the use and storage of highly hazardous chemicals in our communities. Across America, thousands of industrial facilities use and store hazardous chemicals in quantities that put large numbers of Americans at risk of serious injury or death in the event of a chemical release, explosion, or fire. This article focuses on community health risks associated with the use, transport, and storage of hazardous chemicals in communities across America. The aim is to draw attention to the inadequacies of national policies regarding access to information about potentially hazardous chemicals in our neighborhoods.


Background:  Allergic diseases have risen in prevalence over recent decades. The aetiology remains unclear but is likely to be a result of changing lifestyle and/or environment. A reduction in antioxidant intake, consequent to reduced intake of fresh fruits and vegetables, has been suggested as a possible cause.


The purpose of this study is to assess the adoption of international financial reporting standards (IFRS), the benefits, challenges and critical factors affecting its adoption. The study found that Adoption of IFRS would improve the quality of accounting so as to make judgmental decision among users of accounting information. However, Lack of proper financial reporting guidance, Lack of proper instructions from regulatory bodies, additional training for professionals and modernized IT system in handling the transitions to IFRS are the main challenges of IFRS adoption.
