The Hydrogen Safety Panel brings a broad cross-section of expertise from the industrial, government, and academic sectors to help advise the U.S. Department of Energy's (DOE) Fuel Cell Technologies Office through its work in hydrogen safety, codes, and standards. The Panel's initiatives in reviewing safety plans, conducting safety evaluations, identifying safety-related technical data gaps, and supporting safety knowledge tools and databases cover the gamut from research and development to demonstration and deployment. The Panel's recent work has focused on the safe deployment of hydrogen and fuel cell systems in support of DOE efforts to accelerate fuel cell commercialization in early market applications: vehicle refueling, material handling equipment, backup power for warehouses and telecommunication sites, and portable power devices. This paper resulted from observations and considerations stemming from the Panel's work on early market applications. This paper focuses on hydrogen system components that are installed in outdoor enclosures. These enclosures might alternatively be called "cabinets," but for simplicity, they are all referred to as "enclosures" in this paper. These enclosures can provide a space where a flammable mixture of hydrogen and air might accumulate, creating the potential for a fire or explosion should an ignition occur. If the enclosure is largemore » enough for a person to enter, and ventilation is inadequate, the hydrogen concentration could be high enough to asphyxiate a person who entered the space. Manufacturers, users, and government authorities rely on requirements described in codes to guide safe design and installation of such systems. Except for small enclosures used for hydrogen gas cylinders (gas cabinets), fuel cell power systems, and the enclosures that most people would describe as buildings, there are no hydrogen safety requirements for these enclosures, leaving gaps that must be addressed. This paper proposes that a technical basis be developed to enable code bodies to write requirements for the range of enclosures from the smallest to the largest.« less


This project will examine the relationship between the degree of competition between access providers and the price of Internet access in a particular country, as well as the impact of access provider topological characteristics on price and quality. Its purpose is to understand whether greater competition will result in lower network access prices. This project uses a scatter plot to show the relationship between these variables and attempts to build a model to express this relationship. The data used in this project includes Internet access prices and topology information of Internet Service Providers (ISPs). The data set is from the author's previously published article 'Establishing a database of competition between ISPs based on Python language'. The purpose of this paper is to demonstrate the relationship between the price and the bandwidth of the Internet access and the competition among access provider by the method of data analysis. And at the end, we increase the accuracy of the model by adding the possible influence variables.


The third most common disease worldwide, colorectal cancer (CRC) is responsible for around 10% of annual cancer diagnoses. The success of personalized treatment hinges on the ability to recognize biomarkers linked with CRC longevity and forecast the prognosis of CRC patients. The goal of this research is to provide a novel approach to doing multi-attribute colorectal cancer analysis by using machine learning algorithms with multi-criteria decision-making (MCDM) methods and neutrosophic set (NS). The NS is used to overcome the uncertainty in the dataset. This paper used the neutrosophic AHP method to get the weights of features in the used dataset. Then the machine learning algorithms are used to give analysis and prediction of colorectal cancer. The decision tree (DT) and support vector machine (SVM) is used to analyze and predict colorectal cancer. The dataset has nine features like age, gender, dukes stage, location, and Disease-free survival. This paper shows the analysis of the dataset and the correlation among the features.


One of the most difficult methodological challenges in cross-cultural comparisons, especially in the field of intercultural communication, is the difficulty of interpreting and translating knowledge transmitted between cultures. New forms of participation and empowerment in the information society can only take place when the information transmitted by using codes of one culture is successfully interpreted and converted as knowledge in another culture.

Corridor preservation has become an important issue in Utah's transportation planning process. As Utah's population grows, the demand for an improved transportation infrastructure increases. To protect potential transportation corridors from increasing developmental pressures and to preserve these alignments for future use, corridor preservation techniques must be applied. This report, "Methods and Techniques of Corridor preservation: A Guide for Utah Practice", provides a comprehensive look at available corridor preservation tools and offers some guidance for application of these tools within Utah's existing legal and practical environment. While this report does not outline a specific step-by-step approach to corridor preservation, its intent is to provide a review of the many tools provided for use. Transportation planners and government decision makers can then use this report as a reference for developing an effective corridor preservation plan for improvement projects throughout Utah's transportation system. This report consists of two volumes. Volume I is a training manual and consists of the following topics: Purposes of Corridor Preservation, Summary of Available Corridor Preservation Tools, Barriers to Corridor Preservation, Use of Police Power in Corridor Preservation, Use of Advance Acquisition in Corridor Preservation, Use of Developer Agreements and Incentives in Corridor Preservation, Use of Maps of Reservation in Corridor Preservation, Access Management for Existing and Future Corridors, Environmental Issues in Corridor Preservation Programs, Legal Issues Relating to Corridor Preservation, Utah's Existing Legal Framework for Corridor Preservation Activities, and Intergovernmental Coordination and Public Involvement in Corridor Preservation. Its appendix contains a Glossary of important terms, a summary of Utah's recent corridor preservation efforts, and a copy of the National Environmental Policy Act.

Willow short rotation coppice is not very common in Romania. The first crops date from 2006 but were attempts on small areas. There haven't been reported very good results for willow Swedish clones in specific conditions of our country. This is the reason why we try to test biomass production of willow clones on a meadow alluvial soil of Bega River. In this regard, an experimental culture with seven Swedish willow hybrids (Gudrun, Inger, Klara, Stina, Olof, Tora, Tordis) have been established. The aims of this study were to quantify the biometric characters and biomass production on different willow hybrids. The results showed significant differences in terms of shoots biometric characters for all analyzed clones. There have been highlighted correlations between diameters and the height of the shots. In terms of dry biomass, satisfactory results were obtained for clones Olof and Stina.

Cognitive and social neuroscience may provide a wide range of neuroscientific tools and paradigms for the research on competitive behavior. Specifically, hyperscanning is a relatively new paradigm in neuroscience that involves capturing the brain activity of two or more participants engaged in a joint task, such as a competitive game, simultaneously. A brief overview of hyperscanning studies on competition and the intra-brain and inter-brain functional connectivity analysis have been here described. Taking inspiration from previous hyperscanning protocols, this chapter suggests that the neuroscientific study of competitive behavior could also be fruitfully explored in other real-life contexts, such as the educational field, the peer group, the sports field, and the organizational context.


The main empirical conclusion of this paper are: (i) Higher levels of debt are associated with increases in both the level and the growth rate of productivity (ii) Increases in market share are associated with falls in the level of productivity, while companies with a higher market share experience higher productivity growth. (iii) Productivity growth was higher in union firms during 1979-89, and might have been lower during 1975-78.


Channel routing is important in flood forecasting and watershed modeling. The general constant-parameter Muskingum-Cunge (CPMC) method is second-order accurate and easy to implement. With specific discretizations such that the temporal and spatial intervals maintain a unique relationship, the CPMC method can be third-order accurate. In this paper, we derive the average lateral inflow term in the second- and third-order accuracy CPMC method, and demonstrate that For spatially and temporally variable lateral inflow, the effect of lateral inflow on simulated discharge varies with spatial and temporal discretizations, the value and spatial and temporal variations of lateral inflow, wave celerity, and diffusion coefficient. Comparison of the CPMC solution with the analytical solution shows that both the second- and third-order accuracy schemes are more accurate than the simplified method by which spatial derivatives of lateral inflow are ignored. For small time steps, the third-order accuracy CPMC method results in higher accuracy than the second-order scheme even when the third-order accuracy criterion is not fully met. For large time steps, the temporal and spatial discretization of the third- and second-order scheme becomes the same, but the third-order scheme yields higher accuracy than the second-order scheme because of the third-order accurate estimation of the lateral inflow term.


Aimed at checking the signal's nonlinearity and instability of road flatness, in order to get a more convenient and significant approach to verify the pavement smoothness, a road roughness detection method on the base of Permutation Entropy (PE) algorithm is put forward. This method firstly relevantly deals with the collecting road signals, then getting Permutation Entropy (PE), and reaches relevant drawing data array. By the use of Matlab drawing, the road roughness can be proved according to the PE. The experiment turns out that Permutation Entropy (PE) algorithm has an effective and convenient effect on checking road flatness, and it is more obvious to show pavement roughness compared the method of the Holder index.


In his reading of my essay, 'Nation, duty, character, and confidence: history at Oxford, I850-I9I4', Peter Slee raises some questions about the kinds of evidence that best explain the origin and nature of disciplines within the modern university.' He appears to believe that history teachers at Oxford became increasingly specialized and that they saw their essential function as the teaching of disinterested knowledge and objective methods of historical study. Assuming that the Oxford school of modern history can be explained by the content of its teaching, he relies only on three sets of lecture notes, some examination questions, some Examiner's notebooks, and one examination script.' But it is essential that a wider variety of evidence be read critically within the context of a developing university that was part of national life. Inconsistencies between what was said and what was done and between what was expected and what actually occurred must be recognized and explained. It is necessary but not sufficient to recount the steps by which the university accepted the subject of history as part of the evolving structure of colleges and new university bodies, each of which attempted to regulate teachers and their subject. The story cannot be told adequately without an analysis of the relationship between institutional forms and the broad agreement in Oxford about the greater purposes of the university. The emergence of the modern university of Oxford was informed by a prevalent agreement that new subjects must provide a discipline, in both the widest and narrowest sense, for transforming immature young men into responsible and capable leaders, at home and within the empire.3 Although remarkably autonomous and resilient, the university community was never indifferent to internal debate or to the outside world. History developed at Oxford, from the i850s until at least I914, as an increasingly successful part of the modern English university's national commitment. Knowledge was rarely disinterested.4 History teachers or tutors, as classics teachers


In this paper, we introduce the concept of anti Q-f uzzy R-closed KU-ideals of KU-algebras, lower level cuts of a fuzzy set, lower level R-closed KU-ideals and prove some results . We show that a Q-fuzzy set of a KU-a lgebra is a R- closed KU-ideal if and only if the complement of this Q-fuzzy set is an an ti Q-fuzzy R-closed KU-ideal. Also we discussed few results of R-closed KU-ideals of KU- algebras under homomorphism and anti homomorphism. Cartesian Product of Anti Q-fuzzy KU-ideals of KU-algebras are also discussed.


This paper presents studies of multimodal turn management in a Danish corpus of video recorded conversations between two young people who meet for the first time. More specifically, we investigate multimodal behaviours by which the conversation participants indicate whether they wish to give, take or keep the turn. In this study we present quantitative analyses of such cues, as well as an investigation of the length of the individual participants' speech contributions. The quantitative studies comprise body behaviours which have not been previously investigated with respect to turn management, so that it not only confirms preceding studies on turn management in English but also provides new insight on how speech and body behaviours are used synchronously in communication. The investigation of the participants' vocal contributions shows gender differences in that male participants talked more when interacting with a female than they did when their interlocutor was a male, while female participants talked more when interacting with a female than when they interacted with a male.


This is the preface and conclusion of a new book on legal argument.

Pure cultures of a large number of fungal isolates were obtained from anthracnose symptoms developed on the olives collected from Ouazzane and Sidi Kacem regions (North and North West of Morocco). Microscopic observations, based on morphological criteria, identified some of them belonging to the genus Colletotrichum. However, high morphological similarity and sometimes identical host range were exhibited by the Colletotrichum species. Molecular taxonomy has brought the OCol1 isolate to Colletotrichum lupini with a similarity of 96.82%. The GenBank accession number for the nucleotide sequence of this isolate is SUB5832003 OCol1 MN064849 voucher RAB107302. Koch's postulates were applied to know the pathogenicity of Colletotrichum lupini encountered for the first time on the olive tree in Morocco. The leaves and olives inoculated with OCol1 showed circular lesions that were soft and dark. The diameters of the lesions developed in fruits and leaves inoculated with mycelial disks of C. lupini are respectively 1.062 and 0.78 cm. Olives and leaves inoculated by spraying a conidial suspension showed symptoms of rot that affected more than 70% of the olives and 40% of the leaves. 15 days after inoculation, these symptoms developed clusters of orange spores.


Purpose While research and adoption of servant leadership are on the increase, little is known about the mechanisms through which it affects organizational performance. Drawing on the contingency theory, this paper examines the extent to which organizational strategy and structure affect the relationship between servant leadership and organizational performance. Design/methodology/approach Survey data was collected from 336 direct reports of CEOs/GM/MDs in Australian SMEs, and multiple regression analysis was used in the hypotheses testing.  Findings The study found that the relationship between servant leadership and performance is moderated by the three-way interaction effects of differentiation and centralization as well as cost leadership and formalization. Practical implications This study shows that the positive effects of servant leadership on performance are more pronounced in organizations with minimal organizational structure that are not fixated on cost minimization. To that end, ensuring that ...

Three subtypes of alpha-2 adrenergic receptors (<X2AR) have been identified: <X2A, <X2B and <X2C. <X2ARs are known to mediate a number of functions in many tissues. It is not clear, however, what the distribution of <X2AR subtypes is in these tissues. The distribution of <X2AR sUbtypes is fundamental to understanding receptor function and the development of more effective and specific <X2-adrenergic agents for therapeutic use. The working hypothesis for this dissertation is that there are specific subtypes of a2ARs in tissues and in cells that have discrete localizations and may subserve different physiological function. To test this hypothesis two specific aims have been raised. The first aim was: the generation of subtype-specific antibodies. Experiments were conducted to express fusion proteins containing part of the third intracellular loop of each <X2AR. Chickens were immunized with fusion proteins and antibodies were purified from the yolk of the chicken eggs. The antibodies have complete subtype specificity as characterized by immunofluorescence studies on COS-7 cells transfected with DNA encoding the <X2ARs. The second aim was: the immunohistochemical localization of a2AR subtypes in the primary culture of rat spinal cord, anterior segments of human and rabbit eyes and transfected COS-7 cells. Experiments were conducted to localize the <X2AR SUbtypes in cultured cells and tissues using indirect immunofluorescence techniques. The immunofluorescence results were confirmed by alternative approaches, e.g. reverse transcription-PCR,


Robotic therapy has been shown to increase the range of motion, strength, and agility of arm movements in chronic stroke patients, and many researches in this field have been carried out. In this paper, we are proposing a new approach of active rehabilitation for upper limbs. We suppose one of the subject's hands is intact, the other one is injured, and the intact hand can direct the mechanical assistance of his injured hand with this system. We have designed a virtual force model, through manipulating the haptic effectors of haptic devices with one or two hands, a virtual object could be controlled to track a pseudorandom signal in a virtual environment, and the different tracking performance for the two conditions will be appraised. During the process of rehabilitation, the real-time vision feedback of virtual environment will be transmitted to operator's eyes, and the corresponding force feedback of haptic device will be transmitted to operator's hands. A preliminary tracking experiment was conducted wherein healthy subjects, the tracking performance with the combined efforts of two hands is testified better than one hand alone. In the further experiment, we will test the hypothesis the combined efforts of two hands can improve the rehabilitation performance


Variational quantum compiling algorithms \cite{qaqc} aim to compress quantum circuits into parameterized ansatzes utilizing a hybrid quantum-classical approach. In this article a variant of VQC named the recursive variational quantum compiling algorithm (RVQC) is proposed. In contrast with existing VQC algorithms, where one is required to execute the full target circuit in order to compile it, RVQC works by dividing the target circuit into $N$ parts and recursively compresses one part at a time into the parameterized ansatz. Since smaller parts are being compressed at a time, the circuit depth required to implement the algorithm is not dependent on the depth of the target circuit, but on the depth of the ansatz and the depth of each of the $N$ parts. We are hence able to compress the target circuit by executing circuits of smaller depths than the target circuit itself. To show that this approach has an edge over the standard VQC method for sufficiently large circuit depths, RVQC was compared with VQC on a noise model of the IBM Santiago device with the goal of compressing a randomly generated five-qubit circuit of depth 5000. It was shown that VQC was not able to converge within 500 epochs of training. On the other hand, RVQC was able to converge to a fidelity ($0.88$) within a total of 500 epochs when splitting the target circuit into $N = 5$ parts.

Three matched pairs of TAT-type cards, selected from a set described in a previous study of children's attitudes (Vaughan & Thompson, 1961), were shown to 101 firstyear students assigned at random to 2 groups. The scenes depicted were: Formal social occasion (a dance), Play (boys at play), and Vocation (job interview). One card from each of the 3 pairs, in which a central (test) figure was White, was presented to one group (N = 56); the other card of each pair, in which the test figure was Maori, was shown to the second group (N = 45). Each S was given 3 cyclostyled sets of 20 statements to be read while viewing the cards. The statements referred to possible actions by the characters depicted in the cards. Three crucial statements in each set indicated char rhe test figure was socially acceptable to the other depicted characters, e.g., the girl will get the dance, the boy will be asked to play, the girl will get the job. Ss were asked to check those statements considered to describe accurately the scenes. Results are given as the number of occasions (0 to 3) on which test figures were seen as accepted. The criterion of acceptance of a figure was S's agreement with at least one crucial statement relating to that figure. It was hypothesized that more acceptance responses nfould be made when rhe rest figure was White rather than Maori.


Gravity can become strong at the TeV scale in the theory of extra dimensions. An effective Lagrangian can be used to describe the gravitational interactions below a cutoff scale. In this work, we study the diphoton production in {gamma}{gamma}, pp(bar sign), and e{sup +}e{sup -} collisions in the model of low scale gravity. Since in the standard model photon-photon scattering only occurs via box diagrams, the cross section is highly suppressed. Thus, photon-photon scattering opens an interesting opportunity for studying the new gravity interaction, which allows tree-level photon couplings. In addition, we also examine the diphoton production at hadronic and e{sup +}e{sup -} colliders. We derive the limits on the cutoff scale from the available diphoton data and also estimate the sensitivity reach in run II at the Fermilab Tevaton and at the future linear e{sup +}e{sup -} colliders.

The low temperature luminescence and excitation, room-temperature UV-visible and infrared spectra of [Cr( (chxn=trans-1,2-cyclohexanediamine) have been measured. It is found that the zero-phonon line in the excitation spectrum splits into two components by . The eight electronic transitions due to spin-allowed and spin-forbidden are assigned. As expected, nitrogen atoms of chxn ligand have strong properties toward chromium(Ⅲ). The positions and splittings of sharp-line transitions are analyzed as a function of the Cartesian bite () and twist () angles to predict the metal-ligand geometry.


The essence of agricultural project bid is a high-dimensional nonlinear space mathematical optimization problem. In order to improve the generalization performance of SVR algorithm, intelligent algorithm is used to train the SVR parameters, which can make the parameters of SVR optimal. The improved support vector regression evaluation model is applied to the bidding area of agricultural project. The success of some project in some agricultural company proves the reliability and enforceability of the model. The improved model reduces the influence of human factors to improve the objectivity and impartiality of evaluation results.


This paper presents a real time control strategy for dynamically balancing electric demand and supply at local level, in a scenario characterized by a HV/MV substation with the presence of renewable energy sources in the form of photovoltaic generators and an electric energy storage system. The substation is connected to the grid and is powered by an equivalent traditional power plant playing the role of the bulk power system. A Model Predictive Control based approach is proposed, by which the active power setpoints for the traditional power plant and the storage are continually updated over the time, depending on generation costs, storage's state of charge, foreseen demand and production from renewables. The proposed approach is validated on a simulation basis, showing its effectiveness in managing fluctuations of network demand and photovoltaic generation in test and real conditions.


Phase‐shift masks were prepared using sputter deposited films for the phase‐shift layer and etch stop layer on fused quartz silica substrates. It has been found that the combination of SiO2 for the phase‐shift layer and HfO2 for the etch‐stop layer offers a unique combination of properties advantageous for the preparation of phase‐shift masks. The optical transmission properties of HfO2 layers with or without a SiO2 phase‐shifting layer on quartz substrates are presented.


In this contribution a generalized solution for the spectral refinement (SR) of signals is presented. SR essentially consists of a linear combination of weighted and shifted input signal segments (either in the time or the subband domain), yielding a refined (higher resolution) version of the underlying short-term spectrum. The proposed method is particularly suitable for speech processing systems with an existing analysis filterbank based on polyphase or DFT realizations. We first show that DFT-modulated filterbanks that incorporate SR in the time-domain can be seen as a specific realization of polyphase-based analysis filterbanks. Next, the polyphase-based analysis filterbanks will be combined through the proposed generalized form of SR, in the frequency domain. The resulting structure can be applied to refine either the frequencies of the short-term spectrum (or a subset thereof) or to refine the whole frequency range, including additional frequency supporting points. Lastly, as a potential application, we demonstrate the benefit of combining an existing polyphase filterbank with SR for the problem of pitch extraction/fundamental frequency estimation. Especially for lower fundamental frequencies, such combination can give a significant performance improvement compared to estimates based on the original signal spectrum.


Large enterprises are heavily relying on IT technology and infrastructure, which strives to quickly respond and remediate occurring problems, faults, and identify the underlying root causes. To automate this process, the enterprises rely on root cause analysis approach. One of the components is a component discovery module, which also provides information about the dependencies between IT components. In this thesis, we focus on building an IT component dependency graph from granular configuration data automatically. We analyze the configuration data in order to first infer the dependencies between hosts, and secondly, to find the dependencies between IT components. Furthermore, we assign each dependency a likelihood that it exists with a supervised machine learning algorithm. We show that our approach is much faster and accurate compared to the naive approach, which compares configuration parameters to each other. Moreover, we provide an extensive evaluation on the real dataset, where the evaluation takes into account the transitive property of dependencies, and specific properties of the root cause analysis. The evaluation results show that our proposed algorithm reaches 90% recall and 100% precision for discovering dependencies between generic IT components.


This paper explores how reading assessment is used to support 11to 13-year-old students in reading. Learning to be an effective reader of a wide range of texts is critical for students as they reach young adolescence. Using a socially constructed ontology, a qualitative approach was used to explore the perceptions of five principals, seven teachers and nine parents. The five case study schools were situated in low to middle socio-economic areas in New Zealand. The study found that there was a range of methods of assessing reading and analyzing the data, and the analyses of data supported decisions school-wide in supporting low progress readers. Also, students were assessed against the National Standards and this information was shared with parents.


This paper investigates how a university affects firms' location in a context of fiscal competition and how a central government may alter that outcome through the way it provides public funds. The results may be relevant for understanding firms' distributions and the way federal policies might stimulate the establishment of a science park in connection with a university. Particularly, the results may be important if we consider that spillovers of universities might benefit closely located entreprises leaving more distant areas with only low-tech firms. Our findings suggest that Rawlsian and utilitarian planners taking care of knowledge in a country do not contribute at developing science parks connected with a university.


The current study was conducted to identify the best parents with good agronomical features and contrasting characteristics for sucking pest resistance to develop a population that can be used for Quantitative Trait Loci mapping of resistance component traits. Initial attempts at this university have enabled to identify of five potential parents (viz., KC3, NDLH 1938, CO18, K12, and RG8) with improved sucking pest resistance and yield characters and they were crossed with the recently released high-yielding variety CO-17, which is also suitable for high-density planting.  All these six parents were evaluated for fiber yield and quality traits besides anatomical characters such as trichomes density, length, width, and sharpness that confers sucking pest resistance and genotyped with 200 Simple Sequence Repeats markers that span the entire genome. Efforts have been dedicated to the careful selection of optimal parents, namely CO17 and KC3, each possessing distinct traits related to resistance against sucking pests and also fiber quality characters in addition. This strategic approach aims to combine their contrasting genetic components for sucking pest resistance, to develop a new generation of plants that exhibit heightened resilience to these types of pests. CIR139, a polymorphic SSR marker of these two parents was used to fix the true hybrids which were advanced to generate an F2 mapping population.  This population is believed to be useful for QTL mapping of anatomical features that confer sucking pest resistance such as trichome length, density, breadth, and sharpness besides fiber yield and quality traits.


ABSTRACT Functional pituitary reserve in 18 patients with the amenorrhea-galactorrhea syndrome was evaluated using luteinizing hormone-releasing hormone (LH-RH), l-dopa, and chlorpromazine. Gonadotropin release after administration of synthetic LH-RH varied widely from that seen in normal women to that below the normal range; however, cases with pituitary tumor exhibited the lowest responses or no responses to LH-RH. Prolactin release in response to drugs which normally either stimulate (chlorpromazine) or inhibit (l-dopa) its secretion, also varied widely regardless of the presence or not of a pituitary tumor. It is concluded that LH-RH is a reliable test to determine the pituitary reserve in cases of galactorrhea associated with amenorrhea. These results suggest that high prolactin levels associated with a deficient secretion of gonadotropin in response to LH-RH may be indicative of an underlying pituitary tumor, even in the absence of sellar enlargement.


Issue of the treatment of mixed genital infections and prevention of reproductive health disorders caused by them has not lost medical and social significance, which is associated with a high frequency of mixed infections, absence of pathognomonic clinical manifestations, and with a constantly significant frequency of sexually transmitted infections (chlamydia, genital herpes, trichomoniasis, etc.). It should be controlled and rationally limited antibiotics use in connection with a sharp increase in microorganisms' resistance. At the same time proven antiseptics which are used to reduce the infection risk or to treat vaginal infections do not contribute to the formation of resistant pathogens. The purpose of this literature review was to analyze publications about modern antiseptic octenidine dihydrochloride for mucous membranes, skin and wounds and the prospects for it use in obstetric and gynecological practice. Octenidine dihydrochloride (octenidine) was synthesized as a multi-functional antiseptic for skin, mucous membranes and wounds. Today octenidine is an active antiseptic with a wide scope of use and is an alternative to chlorhexidine, povidone iodine, triclosan, etc. Octenidine is a cationic antiseptic of a new chemical group (derivatives of bispyridinamine), is a safe and effective antimicrobial agent with a high level and spectrum of antimicrobial activity. The antiseptic activity of octenidine is achieved within 30 seconds, it is chemically resistant, has proven low toxicity to humans and the environment and high clinical efficacy, does not cause the pathogen resistance, is approved for use from the second trimester in pregnancy and during breastfeeding. Octenidine use with or without combinations should be considered as an integral part of the standard therapy for various types of vaginitis and bacterial vaginosis. Octenidine can become a promising agent for therapeutic indications in gynecology in future, since it surpasses povidone iodine, polyhexanide and chlorhexidine in the efficiency of microorganisms' eradication from the mucous membranes.


Communication costs in providing certificate status information to those who wish to validate public key certificates have been cited as the most expensive component of operating a large scale Public Key Infrastructure. One mechanism for providing certificate status information is a Certificate Revocation List (CRL). This thesis proposes a system for cost effective distribution of CRLs using a combination of multicasting and unicasting. The proposed system for CRL distribution calls for periodic and aperiodic multicasting of Delta CRLs to reduce network bandwidth requirements and peak CRL request rates in unreliable networks. An analytical model and a simulation model are used to compare the network bandwidth requirements of the proposed system against a system which uses only unicasting for CRL distribution. Results show that the proposed MCA system which multicasts Delta CRLs aperiodically requires significantly less network bandwidth and reduces peak CRL request rates. For an example network, the communication cost of the MCA system is 89% less than that of the system which only uses unicasting. The communication costs for the MCA system is also less sensitive to the location of the CRL Repository. The MCA system may be retrofitted to legacy client programs which may only obtain CRLs using unicasting.


Modern sexualities have been studied in various ways as 'orientations', 'identities', 'forms of
existence' and ways of living. The paper explores the implications of diverse conceptualisation
of contemporary sexualities for how we might research them. In particular, it interrogates what
'queer' orientations to the study of sexualities involve, and how these could be developed to
more fully comprehend their vitality.

This paper seeks to contribute to our understanding of a spillover effects of regional social capital on private economy from empirical point of view. A model is constructed, in which an external factor using neighboring capital and remote capital is taken into account. Public investment function in terms of regional expenditure, at the same time, is applied for simultaneous estimation in order to deal with an endogenous feature. Furthermore, the influence of regionally provided social capital on the private sector, located in other area, is examined. The result shows us relatively quite high spillover effect of economically developed regions.

In many modern applications such as renewable energy sources (RESs), DC–DC step-up converters can be used to regulate the input variable and/or low voltage to achieve the desired characteristics such as amplitude and ripples at the output voltage. This article pro-poses a new transformer-less step-up DC–DC converter which, compared to previously presented converter topologies in the same class, can provide a higher variable voltage conversion ratio besides benefits such as decreased voltage stress on the switched-capacitors and power switches. Since the proposed topology is expandable, it can generate much higher voltage conversion ratios with lower, non-extreme duty-cycles which can be provided by a simple and cheap control circuit. The aforementioned advantages make the converter a suitable candidate for numerous industrial applications such as RES applications. Besides the voltage regulation applications, the proposed converter can be employed to extract the maximum power from RESs such as photovoltaic panels. To prove the converter performance, comprehensive comparisons and experiments are performed.


Therapeutic community principles have in recent years become increasingly and often enthusiastically applied. They have also attracted an extensive literature, including, among many, studies by Maxwell Jones (1952 and 1962), Cumming and Cumming (1962), and the contributions to two symposia: in Boston, edited by Greenblatt, Levinson, and Williams (1957) and in this country by Freeman (1965).

To assess the efficacy of transversus abdominis plane (TAP) block as a postoperative analgesic effectiveness. Thirty-three consecutive male patients undergoing retroperitoneal varicocele repair (Palomo technique) were enrolled in this study. Patients were randomly allocated to undergo ultrasound-guided TAP block anesthesia (case group), or conventional spinal anesthesia (control group), rescue analgesia need, nausea, and satisfaction at different time-points (6, 12, and 24 h after surgery). The post-operative evaluation, patients enrolled in the case group expressed significantly less pain on VAS score at rest and on movement at 6 (p = 0.001 and p = 0.001) and at 12 h (p = 0.004 and p = 0.01). Moreover, the need of rescue analgesia resulted significantly higher in the control group (p = 0.03). This is the first study showing that TAP block could be employed as an effective and feasible anesthesia method for the retroperitoneal varicocelectomy. Moreover, our results demonstrate that this method is more effective than spinal anesthesia in the pain control after varicocele repair.


Reaction of N-(4-pyridylcarbonylamino)-1,2,3,6-tetrahydropyridine (2a) with methyl chloroformate afforded the quaternary salt 3a whereas reaction with methyl iodide gave a mixture of 3b and 6. Sodium borohydride reduction of 3a using methanol at −65 °C gave the N-methoxycarbonyl-1,2-dihydropyridine 4a whereas reduction using ethanol at 0 °C gave the 1,2,3,6-tetrahydropyridine 4b. Reduction of 3b and 6 gave rise to a mixture of 4c and 7. Catalytic hydrogenation of 4b and 4c afforded the respective piperidyl derivatives 10 and 11. The pharmacological activities of the products are presented.


The growth of e-shopping usage has provided the new way of marketing and distribution of goods and services. While in the early days of e-shopping, gender gap has existed in using internet, and it is particularly apparent for online shopping. Female recognize high level of risk for e-shopping, and as a result they tend to hesitate to make purchase online. In the current scenario, online shopping has become a convenient medium and save time of the final users of the goods and services. It has changed the pattern of shopping by the customer through modern market. In India, the number of internet users increasing day by day with the change of technology of market for doing business. Therefore, the online shopping spread the way with a very rapid pace in Indian market. The present study focused on online shopping perception by university student's gender wise. Furthermore, we examine the factors for intension of online shopping gender difference by the students'. For the present study, the five point Likert scale has been used to measure the perception between the genders. For the analysis of the study, a structured questionnaire was designed. The sample of 200 students' from two Indian University and on the basis of their availability a convenient sampling method was used. This study reveals that male students' are more interested in online shopping than female students'.


Abstract Artificial basilar membranes made of PVDF(polyvinylidene fluoride) are manufactured using microfabrication processes. The mechanical behavior of PVDF artificial basilar membrane was measured to evaluate its performance as a mechanical frequency analyzer using scanning LDV(laser Doppler vibrometer). The experimental setup consists of the microfabricated artificial basilar membrane, a loud speaker connected to an amplifier for generating acoustic pressure of specific spectral pattern, and a scanning LDV with controlling unit for measuring the displacement of the membrane on the incoming acoustic stimulation. The microfabricated artificial basilar membrane was attached tightly upon a package containing a chamber which can be filled with silicone oil before placed on the experimental setup stage. The experiment results showed that the microfabricated artificial basilar membrane has a property as a mechanical frequency analyzer.

In this essay, I argue that we cannot adequately characterize the aims of education in terms of narrowly intellectual virtues or some formal conception of what it is to think well. Implementing any such aim requires us to rely on, and to communicate, further substantive normative commitments. To put my point another way, there is no adequate ideal of being a good thinker divorced from the content of what such a person thinks or the commitments that she has. Who would have thought otherwise? Consider a familiar debate in the philosophy of education. On the one side are those parents and teachers who understand their educational mission as that of handing on to children a particular worldview or normative outlook. Education set in the context of a religious tradition is a paradigm case, though there are cultural, political, and other versions of this approach as well. On the other side are those who object that education of this sort amounts to indoctrination and fails to respect the autonomy of the students subjected to it. Instead of trying to educate children into a single view, such objectors hold, we should aim to develop their critical thinking and reasoning skills. This latter ideal is put formally: it characterizes an educational goal specified in terms of how we should teach children to think, without reference to the content of what we should teach them to think. The thesis that no such formal ideal could be sufficient to guide education, thus, has important implications for thinking well about how to educate. It reveals that this standard contrast between what I will call, respectively , the old-fashioned and progressive views of education is confused and misleading. 1  My intention here is not to support one of these approaches against the other, but rather to argue that the familiar way of characterizing the supposed opposition mischaracterizes, and so obscures, the most important disagreements between their advocates. I aim to re-characterize the terms of the debate in a way that clarifies what is really at stake. In Section I, I begin by elaborating the two models in a way that I hope brings out the motivation for each. I conclude the section by characterizing


. Comparisons of crop production on recently reinstated soil in Northumberland have shown that the reduced yield potential of such soil may not be inevitable. Storage of soil in bunds did not greatly reduce subsequent crop yields, but failure to drain the land did. Provided an effective drainage scheme was installed, arable and grass crops could be grown successfully, responding very well to additions of nitrogen fertilizer and other normal good husbandry practices. To date it seems that neither deep cultivation nor the use of grass leys were as effective in the restoration process as had been expected.

As applications, we apply the results obtained in this paper to study the existence and uniqueness of positive solutions for a fractional boundary value problem.


Abstract In the north-eastern part of Poland, the underground gas stores are being constructed by diluting salt deposits. Brine, a by-product of the technology applied, is discharged into the coastal waters of the south Baltic Sea by a system of diffusers. To assess the intensity of brine mixing in the near-field of the discharge installation, a monitoring program was carried out. The results demonstrated that under the mildly dynamic conditions of Puck Bay, the discharge of brine (saturation 250 kg m-3, discharge 300 m3 h-1) leads to salinity excess below 0.5 PSU. For parameters of a real brine discharge, the dilution coefficient estimated by formulas derived from analytical solutions, predictive models and laboratory experiments for stagnant water conditions, varied in the range of 123÷360. The dilution coefficient value estimated on the basis of measurements was 1.27÷3.72 times higher than its value obtained by the use of predictive models, while estimated by formulas obtained from laboratory experiments was in the range of 1.41÷2.26 of the dilution coefficient based on measurements.


Key Points Question How has utilization of low-value carotid imaging for carotid bruits, preoperative evaluation, and syncope changed in the Veterans Health Administration system from 2007 to 2016? Findings In this serial cross-sectional study of 809 071 carotid imaging examinations in the national Veterans Affairs Health system, there was a modest decrease in rates of imaging for carotid bruits that predated Choosing Wisely recommendations, and no significant trends in rates of preoperative carotid imaging or imaging for syncope. Meaning These findings suggest that to reduce low-value testing and utilization cascades, interventions targeting ordering clinicians are needed to augment the impact of public awareness campaigns.


The invention discloses a tester for a reverse bubble point of a single filter core. The tester is provided with a sealing cover, wherein the sealing core is coincided with a filter core filtrate outlet and is used for packaging the filter core filtrate outlet; and an air pipe connecting opening is formed in the sealing cover. The invention also discloses a method for testing the reverse bubble point of the single filter core. The method sequentially comprises the following steps of: A, fully soaking and humidifying a membrane filter core by using sterile water; B, connecting the air pipe connecting opening of the tester with a compressed air source through a pipeline; C, connecting the sealing cover of the tester to the filtrate outlet in the membrane filter core in a sealing way, immersing the whole filter core in the sterile water, and introducing compressed air into the filter core through the compressed air source; and D, observing a testing result, if bubbles are continuously and regularly generated at a certain fixed position of the filter core, determining that the filter core is an integral unqualified filter core, and otherwise, determining the filter core is an integral qualified filter core. By the tester and the test method, the reverse osmosis integrality of the membrane filter core can be tested.


We critically discuss a recently proposed technique by Barron et al. (2008a) to estimate the remnant pressures acting on inclusions that are trapped in diamond singlecrystals, from the observed strain birefringence of the surrounding host diamond. These authors claim to have found that the extent of compressive strain in the host diamond adjacent to inclusions of other minerals, determined from the upshift of the position of the diamond LO1⁄4TO band in Raman spectra, would be proportional to the maximum strain birefringence in the diamond. Based on the (as we believe, unjustified) assumption of general pressure/strain equilibrium within the inclusion-host diamond couples, Barron et al. (2008a) propose to use this correlation as a simple means to determine remnant pressures acting on inclusions, and they claim the applicability of their technique would not be affected by the type of the included mineral or its shape and orientation. We discuss, and demonstrate, that the technique proposed by Barron et al. (2008a) is guilty of a number of serious simplifications and is likely to yield wrong, and thus misleading, results. Therefore, we suggest that this technique should not be used in the evaluation of unknown inclusions in diamond specimens. Barron et al. (2008a) have presented a spectroscopic study of a small number of mineral inclusions in diamond crystals. They use the pressure-induced shift of the main diamond Raman band, which is usually described as the LO1⁄4TO mode (optical vibrations of diamond are degenerate due to the high point-group symmetry of the crystal structure, and longitudinal– transverse splitting does not occur), to quantify compressive strain in diamond specimens adjacent to inclusions (Nasdala et al. 2003). Barron et al. (2008a) compare these data with the rarely used method of quantitative birefringence analysis, to estimate remnant pressures acting on inclusions. Any study of this kind is based upon a number of theoretical assumptions in order to quantify the elastic behaviour of both the host and mineral inclusion. Without making sure that these assumptions are valid for the samples being studied, it undermines the validity of the results obtained. In our opinion, the approach of Barron et al. (2008a) is guilty of an oversimplification. It fails to consider any of the fundamental assumptions of the principal theory, as described by many of the early studies in this field (Rosenfeld & Chase 1961; Harris et al. 1970), or the underlying photo-elastic tensor theory (Nye 1957), in dealing with stress-induced birefringence. We highlight some of these assumptions that have been overlooked, and discuss their impact on the analysis. Many of the early studies that attempted to quantify the elastic effects around solid mineral inclusions have focused on garnet inclusions in diamond, perhaps stimulated by the cubic crystallography of both the host and inclusion. Theoretically this meant that the expansion of the inclusion would be isotropic, resulting in an equal radial stress regime in the surrounding host. In contrast, if a uniaxial or biaxial mineral inclusion is studied, it is crucial to assess how it will expand and transmit the remnant pressure to the surrounding host diamond. An example is shown in Figure 1. These are images of diamond PAG12 containing a large, single-crystal graphite inclusion, from the Ekati diamond mines, Panda district, Canada. This specimen has been discussed in detail by Barron et al. (2008a), based on results of Nasdala et al. (2005). Note that the graphite singlecrystal is likely to have undergone extensive volume expansion along {001} upon pressure release, whereas expansion within the crystallographic a–b plane was perhaps almost negligible (Zhao & Spain 1989). As a


The study of stress is a very important problem especially in the case of welded structures. Very often the main causes of their failure are represented by the overlap of the stresses during operation with the remaining ones during the welding process. The article presents in the first part the experimental activity that regarding the realization of some fillet welded joints remedied by two processes that aim at reducing the internal stress. In the second part of the article, starting from the experimental part presented, a model was made by the finite element method. Based on it the different states of tension resulted in the initial structure as well as in the rehabilitated ones were simulated.


Regular and standardized integration of palliative care represents an important evolution in modern delivery of serious illness care in the intensive care unit (ICU). As clinicians, administrators, and patients place greater value on care processes to support quality of life, there is a corresponding need to ensure those processes are delivered in expected ways. Ensuring that these demands are met requires the development and validation of quality metrics to continuously evaluate the quality of palliative care delivered in ICUs. A quality metric is used to quantify the rate at which an expected care process is delivered within the population eligible for that process. To be a valid judgment of the quality of care an individual or organization provides, the metric must be measurable, controlled by the medical provider or organization, and reasonably correlated to outcomes that are valued by patients, payers, or policymakers (1). The ICU presents a unique challenge in measuring palliative care quality. Unlike many other settings in which palliative care is delivered, ICU care is uniquely multidisciplinary and collaborative, dominated by seriously ill patients, and challenged by care that is complex and often longitudinal. There is clear consensus that integrative palliative care is important in ICU care (2), which encompasses delivery by both ICU specialists and, occasionally, palliative care experts. Although enhancing various aspects of ICU-based palliative care has shown improvements for patients and families in multiple domains (3–5), there remains little consensus on the optimal outcome measures (5, 6), perhaps in part because the primary outcomes of several important clinical trials of palliative care interventions have been negative (4, 7–9). Nearly a decade ago, the Robert Wood Johnson Foundation and the Society for Critical Care Medicine put forth 18 candidate quality metrics for integrating palliative care into ICU Care (RWJF-SCCM metrics) (10). These have yet to be widely adopted, possibly as a result of unproven feasibility and a lack of evidence linking these measures to relevant outcomes. In this month's issue of AnnalsATS, Mularski and colleagues (pp. 690–698) have provided an important advancement in measuring palliative care quality in the ICU. In doing so, they endeavored to forge a crucial link between standardized palliative care processes and improved outcomes (11). They further validated the RWJF-SCCM metrics, using a structured consensus process; demonstrated the feasibility of evaluating 14 process measures of palliative care quality in routine medical documentation within the ICU; and correlated those processes with complementary outcomes using nursing and family assessments (12, 13). The authors found that the proposed measures were feasibly abstracted from the medical records of two academic ICUs, but that there was no correlation between these measures and outcomes assessed by nurses or patients. The study was powered to demonstrate a difference in the composite quality metric adherence between two affiliated hospitals, and this result was negative. However, they did find statistically significant differences in three individual processes; namely, documentation of spiritual support, documentation of decisional capacity, and transfer of key information out of the ICU. The study represents a key step in evaluating the implementation of RWJF-SCCMmetrics to evaluate delivery of palliative care in the ICU. The authors achieved their primary objective, demonstrating validity and feasibility of the metrics. These were assessed in two common electronic health record systems (Epic and CPRS/Vista), suggesting they could be implemented widely across the country. Although abstracted manually in this study, one could imagine automating the data abstraction and reporting process, thereby reducing the reporting burden and allowing units to benefit from real-time feedback. The patient-centered outcome measure is a well-validated measure of patient and family satisfaction in the ICU (FS-ICU) (13), and the nursing outcome is a measure that mapped directly to the process measures being assessed providing intrinsic face validity. Most important, the performance on process measures of palliative care demonstrates a stubborn gap between known best practices and implementation. There are important limitations to this study. First, by including only two academic ICUs sharing many staff, the generalizability of the results across different types of ICUs and different regions is uncertain. Second, the measured outcomes themselves may not be ideal. For example, the FS-ICU appears to


One of the basic principles of forest management underlines that any type of silviculturalintervention must serve the end purpose of creating stand structures able to fulfill productive orproductive and protective functions, established in detail through management planning. Althoughwood production is still the main focus, depending on the region, forests are also expected to coversociety's growing demand for non-wood products and services such as landscape services, carbonstorage, biodiversity protection or supporting community livelihood in rural areas. Thismultifunctional approach in forest management raises the challenge of creating the suitable structurethat can cover, in a sustainable way, all the demands of local or regional populations. Starting from theabove mentioned issues, the present paper considers the structure of a natural, uneven aged stand,indicated through biometric parameter analysis, as a pattern for multifunctional forestry. The studyrefers to specific conditions in a forest area administrated by "Podu Iloaiei" Forest District, part of"Iasi" County Forest Administration.


Terryl L. Givens. The Viper on the Hearth : Mormons, Myths, and the Construction of Heresy . New York: Oxford University Press, 1997. x + 205 pp., with index. $35.00. Reviewed by Richard H. Cracroft Mormon studies scholars and aficionados-and even an enlightened gentile or two-will welcome Terryl L. Givens's The Viper on the Hearth , a landmark study of anti-Mormonism and its reflections in nineteenth-century American fiction. Givens, himself a Latter-day Saint and associate professor of English at the University of Richmond, breaks new ground in his sound scholarly examination of "the long and tumultuous relationship between Mormonism and American soc iety" (p. 5). Givens' s probing of ni neteenthand twentieth-century anti-Mormon fiction in the contexts of American cultural, social, and religious hi story discovers a number of typical patterns that put us far on the way toward understanding earl y and late anti-Mormon defamation and persecution, ant i-Mormon construction of Mormon heresy, and anti-Mormon demonizing of the Mormon people. In "Mormonism, Politics, and History," part 1 of his closely and well-argued treatise, Givens establishes the Mormons as a unique people, the best example in U.S. history of an " indigenously developed ethnic minority" (p. 16). Placing Mormonism in well-elucidated contexts with other new American religions and Roman Catholicism, he chronicles the history of relig ious persecu tion and vio lence levied against the Latter-day Saints by Christian majorities as well as the aggressive anti-Mormon actions of the U.s. Presidency, Congress , and Supreme Court. In hi s examination of anti -Mormon literature, Professor Givens undertakes to answer at least five quest ions that have puzzled the much-maligned Lauer-day Saints since 1830: (I) Why was the response to Mormonism and its relatively small handful of members so disproportionate to the so-called "crimes" of Mormonism? (2) Why, in an age of general opposition to (a) Spiritualism, 48 FARMS REVIEW OF BOOKS 9(2 (1997) (b) Christian Science, (e) Mesmeri sm, (d) the Grahamites, (e) the Millerites, (f) Utopianism, or (g) Transcendentalism, was antiCatholicism the only antagonism which approached in virulence. although not in persecution and violence, the anti-Mormon crusade of 1850-90? (3) Why, in a nation which prided itself on plurali sm and religious tolerance. did America's "one nati ve re ligion" become the most glaring and anomalous exception "to the American rule of universal toleration"? (p.20)how, in other words. did nineteenth-century anti-Mormon critics reconcile their Jeffersonian religious ideology of tolerance amidst pluralism (e pluribus unum) with a rhetoric of vituperation and exclusion against minority religions in general and Catholicism and Mormonism in particular? (4) What was it in Mormonism. asks Givens, that " lifted it out of the realm of simple religious nonconformity and into the realm of heresy" (p.75)? (5) Finally, he asks why, after 160 years, Mormonism is sti ll assailed , on one hand, by detractors as "heresy," "cult," or "non-Christian," while on the other hand, soc iologists and theologians predict that the worldwide acceptance and growth of the Church of Jesus Christ of Latter-day Saints place Mormonism "on the threshold of becoming the first major faith to appear on earth since the Prophet Mohammed rode out of the desert" (p. 80). Givens addresses these questions very thoroughly, and following him through the dense complexit ies of his answers not only takes the reader on a quick but intensive march through nineteenth-century American religious hi story, but. in an age of nearly universal literacy, through a survey on the power of the Nativist and popular press in identifying. ostracizing. and demonizing more or less helpless minorities, such as the always unpopular Mormons. Just how unsavory the Mormon reputation had become by the 1880s, at the height of the anti-polygamy turmoil in Utah and Congress. is illustrated by a sermon given in Brooklyn on 2 October 1881 by the Reverend Thomas De Witt Talmage. Attempting to console his parishioners who had been shaken by the ineffectuality of their prayers in behalf of President James Garfield, who had been murdered by an assassin , Talmage, referrin g to an early report that the assassin was allegedly a Mormon, proclaimed that, "if the death of Garfield shall arouse the nation to GIVENS, VIPER ON THE HEARTH (CRACROFT) 49 more hatred of that institution of Mormonism, ... he will not have died in vain." No one knew for sure, he continued, but if the assass in were not a Mormon, the vile wretch clearly "had the ugliness of a Mormon, the licentiousness of a Mormon, the cruelty of a Mormon, the murderous spirit of a Mormon" (p.40). In fact, the popular image of the Mormon was that of a degenerate, sensual, evil, and profligate outcast, a kind of Hunchback of the Eighteenth Ward, and a threat to traditional American values of family and fireside. Givens lifts his Viper on the Hearth image from a 1911 Cosmopolitan series attacking Mormonism, in which the author attempts, as journalists had done for over fifty years, to make the Mormons appear as Strange, Other, Exotic, Immoral. Fanatic, and Alien. Givens explores what Gary Bunker and Davis Bitton refer to as a "ritually recited litany" of Mormon offenses (p. 47), a list not unlike the offenses of anti-Catholicism-with a twist: From Mormon religious peculiarities, based on ongoing revelation and additional holy scripture, through their phenomenal missionary success, communali stic economic practices, and their doctrinal exclusivity, to their claim that all other Christian churches are apostate, Mormons exasperated Christian clergy by insisting on restoration not reformation; by claiming "a monopoly on the path to salvation" (p.5); by announcing that hi storic Christian orthodoxy is heresy, while the upstart Mormon heresy is simply ur-Christian orthodoxy. Nativists, already suspicious of Catholic loyalty to Rome, found ways to transform Mormon loyalties to Salt Lake City into an implicit threat to the constitutional prinCiple of separation of church and state; and since. after all, both Catholics and Mormons sponsored secret ceremonies "of dubious repute" and encouraged "the licentious or economic exploitation of women" (p.47), it became evident that Mormons, like Catholics, were indeed "a peculiar people" and thus "Other," dismissible, and expendable . Hav ing established the contexts of his study, Dr. Givens undertakes in part 2. "Mormonism and Fiction." a consideration of the image of the Mormon as it slithers its way among a selection of the fifty-six anti-Mormon novels written between 1853 and 1900, and, gentled and di sgu ised, raises its still-ugly head amid fiction written late in the twentieth century. (I wish Givens had 50 FARMS REVIEW OF BOOKS 9fl (1997) included a bibliography of these anti-Mormon novels from both centuries-especialiy since one wonders about his exclusion of such anti-Mormon authors as Joaquin Miller, " Bill" Nye, and Marietta Holley, who, as "Josiah Allen's Wife," made devastating comic attacks on Mormon polygamy, especially in My Wayward Partner [1 880]. I also wish that Givens had treated the large and influential body of anti-Mormon fiction of Greal Britain, Ger-


This paper deals with optimized multiple-input multiple-output (MIMO) channel estimation and ensuing information throughput conveyed by pilot-based multi-antenna systems affected by both spatially colored multiple access interference (MAI) and errors in the available channel estimates. The architecture of the minimum mean square error (MMSE) MIMO channel estimator is derived and the related analytical conditions for the optimal design of space-time training sequences are provided. Afterwards, closed form expressions for the maximum information throughput sustained by the considered systems for Gaussian distributed input signals are given and, then, a novel power allocation algorithm for the asymptotical achievement of the system capacity is developed. Some final MAC considerations are pointed out.


In a previous paper the absorption of γ-rays in the K-X-ray levels of the atom in which they are emitted was calculated according to the Quantum Mechanics, supposing the γ-rays to be emitted from a doublet of moment f ( t ) at the centre of the atom. The non-relativity wave equation derived from the relativity wave equation for an electron of charge — e moving in an electro-magnetic field of vector potential K and scalar potential V is h 2∇2 ϕ + 2μ ( ih ∂/∂ t + eV + ih e/μ c (K. grad)) ϕ = 0. (1) Suppose, however, that K involves the space co-ordinates. Then, (K. grad) ϕ ≠ (grad . K) ϕ , and the expression (K . grad) ϕ is not Hermitic. Equation (1) cannot therefore be the correct non-relativity wave equation for a single electron in an electron agnetic field, and we must substitute h 2∇2 ϕ + 2μ ( ih ∂/∂ t + eV) ϕ + ih e/ c ((K. grad) ϕ + (grad. K) ϕ ) = 0. (2)


Buck Ewing (1859-1906) was regarded by contemporaries as the greatest catcher and all-around player of his era, though he is virtually forgotten today. A lifetime .300-hitter, he played every position on the diamond and led the league in fielding at two different positions. The first hitter to reach double digits in home runs, Ewing once stole six bases in a game, pioneered the snap forearm throw to catch runners napping, averaged 35 steals a season, and is the only catcher to lead his team in stolen bases (53 in 1888). Off the field, Ewing's personality proved as multifaceted as his playing skills. Considered both affable and modest, he still received criticism from fellow players for negotiating contracts directly with the National League and was accused of faking injuries. This revealing biography provides a detailed exploration of Ewing's life and career, shedding new light on one of baseball's most talented and versatile players.


long literature on housing economics has noted that a rise in mortgage rates could "lock-in" an owner to his or her current house, thereby slowing or preventing a permanent move to a new residence if mortgage interest rates rise sufficiently to make the new debt service payment unaffordable (see, for example, Quigley [1987, 2002]). Other financial frictions—such as the one arising from California's Proposition 13 property tax rules, which essentially imply an often large increase in property taxes after a move—would have similar effects on household mobility (Ferreira 2010). Negative equity, by which we mean the current value of the house is less than the outstanding mortgage balance, could also reduce mobility if the owner lacks sufficient liquidity to pay off the full loan balance, which is required for a permanent move and sale of the property if the borrower is to avoid the cost of a default (Stein 1995; Chan 2001; Engelhardt 2003). These three potential financial frictions are all associated with the sale of the house, so there is a transfer of economic ownership, not just a change of residence. Thus, the type of household mobility that may be impacted by these frictions involves permanent moves in which both physical location and economic ownership change for the previous owner. The housing literature on financial frictions does not have clear implications for temporary moves in which the owner leaves the house for a period of time—perhaps to rent it out—and


This DOE Early Career Award has enabled Dr. Michael Kohl to take on and expand his leadership roles in several projects such as TREK@J-PARC, OLYMPUS@DESY, MUSE@PSI, and in the experimental program in Hall C at Jefferson Lab. Dr. Kohl has successfully accomplished several items: (i) Preliminary results from SANE (E08-003) at Jefferson Lab: Former HU graduate student Anusha Liyanage has pursued her PhD research on SANE. Her analysis of the elastic ep scattering data has resulted in the extraction of the proton electric-to-magnetic form factor ratio from double spin asymmetries at the highest momentum transfer to date. The results are almost final and a publication is in preparation. (ii) Approval of TREK/E36 for running, preparation of simulation and analysis: the TREK experiment has been stage-II approved in fall 2013, has been mounted on the hall floor from November 2014 to April 2015, has been commissioned in April-June 2015 and is scheduled to run in fall 2015. The group has contributed significantly with simulations and magnetic field map calculations, has investigated the sensitivity of TREK to new light neutral particles, and contributed substantially to the mounting and commissioning of the experiment. (iii) Running of OLYMPUS and analysis: Under Dr. Kohl's leadership as spokesman, the OLYMPUS more » experiment has completed data taking beginning of 2013; calibrations and analysis have been well underway, with results to be expected in the course of 2015. (iv) Operation of GEM detectors at OLYMPUS and MUSE: The GEM telescopes built for OLYMPUS luminosity monitoring with forward-angle ep elastic scattering have been operated successfully, have meanwhile been relocated to PSI, and have been re-commissioned as beam particle trackers for the PSI secondary beams for MUSE. (v) Trained and prepared postdocs and graduate students for their future careers. Two postdocs from Dr. Kohl's group (Dr. Juergen Diefenbach and Dr. Peter Monaghan) have found permanent academic positions. Two former graduate students of the group have graduated and received their PhD degrees in nuclear physics (Dr. Anusha Liyanage and Dr. Ozgur Ates). In particular, this award has enabled Dr. Kohl to pursue the TREK project (Time Reversal Experiment with Kaons) at J-PARC, which he has been leading and advancing as International Spokesperson. Originally proposed as a search for time reversal symmetry violation [6], the project has evolved into a precision test of lepton flavor universality in the Standard Model along with sensitive searches for physics beyond the Standard Model through a possible discovery of new particles such as a sterile neutrino or a neutral gauge boson from the hidden sector in the mass region up to 300 MeV/c2 [7]. Experiment TREK/E36, first proposed in 2010, has been mounted between November 2014 and April 2015, and commissioning with beam has been started in April 2015, with production running anticipated in early summer and late fall 2015. It uses the apparatus from the previous KEK/E-246 experiment with partial upgrades to measure the ratio of decay widths of leptonic two-body decays of the charged kaon to µν and eν, respectively, which is highly sensitive to the ratio of electromagnetic charged lepton couplings and possible new physics processes that could differentiate between μ and e, hence breaking lepton flavor universality of the Standard Model. Through the searches for neutral massive particles, TREK/E36 can severely constrain any new physics scenarios designed to explain the proton radius puzzle [12, 13]. « less

It would be say that 1) new fields of biomassproduction and fermentation production, and 2) wastes treatment and resources recovery using with microbial functions were disussed concretely in this article.


This article examines the sacralisation of festival and rave culture. Beginning with an exploration of the British free festival as a site of countercultural ideology and alternative spirituality, it traces the spiritual and ideological lines of continuity between the free festivals that took place with increasing frequency in Britain throughout the 1970s and into the 1980s and the rave culture of the 1980s and 1990s.


This document presents a theoretical model of a non-benevolent regulator and cost heterogeneous operators where the objective function to be maximized, besides considering consumers' and producers' surpluses, includes rent seeking from at least one of the operators that directly benefits the regulator. Under these conditions, the resulting regulatory contract complies with individual rationality and incentive compatibility; however, it introduces distortions that affect the most efficient operators resulting in costs to society as a whole. The main results from this model point towards the need to evaluate the relevance of maintaining regulation under such settings.


Results of Monte Carlo simulations of the Comptonization of photons in a finite spherical Comptonizing cloud are presented. The energy dependence of the arrival times of the Comptonized photons is very different for different input photon spectra. If the delays observed in the high-frequency QPO of Cyg X-2 and GX5-1 are the result of Comptonization, multichannel time-delay measurements may constrain the energy of the input photons and thus provide important information on the accretion process in low-mass X-ray binaries.


In this paper, we use a model selection criterion to decide whether two cylinders should be merged as a single cylinder or they should be left separated. We compare and evaluate an extensive number of different model selection criteria for this purpose and examine which factors can affect their performance. We conclude that SSC, GIC, MCAIC and CAIC have a better performance (for this particular application) compared to the other criteria.


We propose a novel dimension reduction method for classification using a probability-based distance and the technique of locally linear embedding (LLE). Logistic discrimination (LD) is adopted for estimating the probability distribution as well as for classification for the reduced data. Different to the supervised locally linear embedding (SLLE) that is only used for the dimension reduction of training data, our probability-based locally linear embedding (PLLE) can be applied on both training and testing data. Five microarray data sets in high dimensional spaces, the IRIS data, and a real set of handwritten digits are experimented. The numerical results show that our method performs better, compared with the LD classifiers applied on the LLE or SLLE mapped lower dimensional data.


In this work a new algorithm to improve the performance of opti- mization methods, by means of avoiding certain local optima, is described. Its theoretical bases are presented in a rigorous, but intuitive, way. It has been ap- plied concretely to the case of recurrent neural networks, in particular to MREM, a multivalued recurrent model, that has proved to obtain very good results when dealing with NP-complete combinatorial optimization problems. In order to show its efficiency, the well-known MaxCut problem for graphs has been selected as ben- chmark. Our proposal outperforms other specialized and powerful techniques, as shown by simulations.


In the management ofthe photodermatoses it is important that the diagnosis is correct, i.e. that photosensitivity is in fact present. Often this can be suspected on clinical grounds alone but, except in those instances where the abnormal reaction to light is short-term, confirmation by phototesting is necessary. In this way the responsible wavelengths will be determined and the action spectrum defined. This will allow for the selection of an appropriate photodermatosis label and may also direct attention to specific causal factors. In reactions of exposed skin to external agents, light sensitivity is only one possible explanation and less likely to be responsible for the reaction than external irritants or allergic sensitizers. Although certain distribution characteristics strongly suggest photosensitivity, such as the involvement of the edge of the pinnae and of the mastoid area in the male, and the sparing of exposed sites partially protected by variation of hair styles in the female, other features of cutaneous photosensitivity may become obscured, particularly in photosensitivity dermatitis. The expectation that all exposed skin will react is often not fulfilled, especially in the female with polymorphic light eruption in whom the skin ofthe face may not be involved for reasons which have yet to be satisfactorily explained. Also, in those photodermatoses where the photosensitivity is marked, covered skin will react following penetration of certain modern fabrics by the responsible wavelengths. Similar involvement away from the exposed skin will occur as part of the response to contact allergens and other features of a dermatitis; once again this aspect is of particular relevance in the photosensitivity dermatitis and actinic reticuloid syndrome. Also, the eruption may not always be confined to the sunshine months atid in the photosensitivity dermatitis and actinic reticuloid syndrome in particular those affected may not show any obvious worsening during these months on account of the broad action spectrum involving UVR and light which is present all the year round. Perhaps more important still is the added


This paper describes selected effects of body contact of earthworms Dendrobaena veneta Rosa with local anaesthetic (LA) drugs used for human anesthesia (lidocaine and prilocaine) and anaesthetics for aquatic animals (MS-222). The findings showed safe and effective immobilization of earthworms with prilocaine at a concentration of 0.25-1%. At the applied concentrations lidocaine was safe, but less effective. On the other hand, MS-222, at the applied concentrations had a strongly irritating effect for earthworms and induced convulsive body movements connected with a discharge of coelomic fluid. The results may be relevant both for improving the welfare of earth worms during experiments and for the organization of research involving testing drugs on invertebrates. In this case, by using earthworms as an experimental model and by applying the method for measuring their mobility after contact with anaesthetics, which has been described in this article, it might be possible to replace experiments on guinea pigs, rabbits, rats and mice, which are expensive and require an approval of an ethics committee, with laboratory tests on earthworms.


This paper takes four state-owned commercial banks and five newly founded banks as research samples.According to the DEA,this paper computes economic efficiency of the nine commercial banks from 1997 to 2001.Then we investigate the determinants of banking efficiency in China by using a multivariable linear regression model with economic efficiency as dependent variable.The results indicate that several main factors affect banking efficiency,including bank capital adequacy,loan condition,human resource quality,and management level.


In this study, we designed and applied physical computing lessons for elementary 6th-grade students based on the software education guidelines in the Korean 2015 Revised National Curriculum (Ministry of Education, 2015a). The participants of this study were ten 6th-grade students of an elementary school in Gyeonggi-do province in Korea. The physical computing lessons used in this study supported the active interaction of the digital world and the physical world by constructing a physical model using specific media, and controlling it with a program. In order to understand the changes in the students' computational thinking after the class, we analyzed these changes in terms of computational concept, computational practice, and computational perception. Research has shown that physical computing lessons materialize students' computational concepts through computational practices, and improve their computational perspectives through the use of authentic contexts. We expect that the physical computing lessons and analysis tools developed through this study will provide educational implications for future software education.


This study involves the evaluation of the effect of certain stabilizers, that is, citric acid (CT), tartaric acid (TA) and boric acid (BA) on the degradation of ascorbic acid (AH2) in oil‐in‐water cream formulations exposed to the UV light and stored in the dark. The apparent first‐order rate constants (0.34–0.95 × 10−3 min−1 in light, 0.38–1.24 × 10−2 day−1 in dark) for the degradation reactions in the presence of the stabilizers have been determined. These rate constants have been used to derive the second‐order rate constants (0.26–1.45 × 10−2 M−1 min−1 in light, 3.75–8.50 × 10−3 M−1 day−1 in dark) for the interaction of AH2 and the individual stabilizers. These stabilizers are effective in causing the inhibition of the rate of degradation of AH2 both in the light and in the dark. The inhibitory effect of the stabilizers is in the order of CT > TA > BA. The rate of degradation of AH2 in the presence of these stabilizers in the light is about 120 times higher than that in the dark. This could be explained on the basis of the deactivation of AH2‐excited triplet state by CT and TA and by the inhibition of AH2 degradation through complex formation with BA. AH2 leads to the formation of dehydroascorbic acid (A) by chemical and photooxidation in cream formulations.


P I L o E n E c T I o N is a rudimentary and presumably worthless function in man, in contrast to its value to lower vertebrates, notably the fur bearers and the porcupine. The smooth muscle effectors (arrectores pilorum) are innervated by the sympathetic nervous system. Involvement of the pilomotor apparatus by a discharging lesion in the central nervous system is a rare event. The patient herein described is the first to our knowledge in whom paroxysmal piloerection was the principal manifestation of a cerebral tumor.


In Hong Kong, the University Grants Commission (UGC) recently asked universities to respond to a letter on how best to assess research quality and impact (UGC, 2008), making reference to a UK paper on research assessment that proposes the use of bibliometrics for evaluating research in laboratory-based disciplines, with the possibility of developing suitable bibliometrics for non laboratory-based disciplines in future (Evidence Ltd., 2007; Van Raan et al., 2007). Clearly, this will ensure that universities look carefully at how to maximize the measurable impact of their research. One possibility is to encourage open access publication. In addition, UGC is now reviewing how best to measure and increase Knowledge Transfer (KT) in Hong Kong universities. For any reasonable definition of KT, increasing public access to research done inside universities clearly increases KT and should be encouraged, which suggests another reason to encourage open access publication.


GA3 enhances the elongation growth of early dwarf rice (Oryzae sntiva cv, I-Geo-Gen) seedlings. Markedly preceding growth of the shoots is an increased RNA synthesis, as shown by total RNA determination and 32P-incorporation into RNA. But the increase in DNA content is later and is evident after treatment with GA3 for 4 days. ABA inhibits shoot elongations, nucleic acid and protein synthesis. When GA3 is added together with ABA, it is found: 1) the inhibition of shoot growth by higher concentration of ABA (above 5 x 10^(-5) M) can't be overcome by the additton of GA3 even at reasonably high concentration. 2) the inhibition of growth by ABA below the concentration of 5 x 10^(-5) M can be gradually overcome by increasing the cone, of GA3. When ABA (5 x 10^(-6)M) is added together with 5 x 10^(-4) M GA3 for 5 days, shoot length of the dwarf rice seedlings reaches the level of dist, water control. RNA content is largely reversed, but the content of DNA, protein and shoot dry weight, though increased slightly, are still markedly inhibited over 50%. These results suggest that the interaction between GA3 and ABA is partial, incomplete and non-competitive, i. e., GA3 can only overcome part of the inhibitory action of ABA, while the other part, maybe the most part, on which they both act differently and independently can't be overcome by the addition of axogenous GA3. In addition, the interaction between these 2 hormones in the control of seed germination, α-amylase synthesis in embryoless half endosperms, and root growth o f seedlings are studied and discussed.

This thesis could be a rough guide for potential investors, how to behave on the stock markets and what to focus on.


Abstract The article deals with the view of modern wheelset drive construction design in the first part. Next part deals with dynamics of the wheelset individual drive torsion system in electric traction vehicles, explained by the drive model in several variants. The basics of time simulation of the transition dynamics effects have been explained and the frequency analysis of the system has been shown. Identification of transition dynamics effects in the wheelset drive enables to evaluate precisely the loading on individual parts during the design stage, to apply the results in anti‐skid protection and probably also to disclose some effects due to wear in the wheel‐rail contact.


The use of conservation easements has risen dramatically over the past twenty years, resulting in the protection of millions of acres of conservation land and historic properties. The land trust community-a diverse collection of thousands of individual land trusts, big and smallhas helped drive this success. Unfortunately, a wave of scandals threatens to jeopardize these accomplishments. A recent series of articles by the Washington Post exposed abuses by the world's largest land trust, The Nature Conservancy (TNC), including the apparent exploitation of tax benefits garnered from donation of conservation easements that involved excessive easement appraisals or land with dubious conservation value. Subsequent investigations by Congress and the Internal Revenue Service revealed additional problems, including insufficient monitoring and enforcement of conservation easements, and sounded calls for broad legislative and regulatory reform. The Congressional Joint Committee on Taxation proposed draconian restrictions on tax deductions for gifts of land that could lead to a sharp reduction in donated conservation easements. In an effort to ameliorate these concerns and avoid federal intervention, the Land Trust Alliance (LTA) - the umbrella organization for the nation's land trusts-launched a new accreditation program for individual land trusts. The accreditation program aims to restore the public confidence, assure long-term protection of conservation easements, and deter governmental intrusion. This Comment discusses the concern among some in the land trust community that top-down oversight will drive smaller land trusts out of existence and erode or
