On 13 October 1967 Virginia P. and Robert C. Greenlease donated a walnut crucifix by French sculptor César Bagard to Rockhurst University's Jesuit community in Kansas City, Missouri. This gift initiated a collaboration of thirty years between Mrs. Greenlease and Rockhurst's president, Father Maurice E. Van Ackeren, S.J. Together they sought to enhance the university and its students' spiritual and educational experience by making fine religious works of art accessible for viewing on campus. Virginia financed the purchases that Father Van Ackeren made, the sum of which came to be known as the Van Ackeren Collection of Religious Art. Throughout their endeavor, the two took advantage of the expertise of the curators of the William Rockhill Nelson Gallery of Art in Kansas City, Missouri (now known as The NelsonAtkins Museum of Art) and employed that institution as an intermediary station for evaluating works before they were purchased. The majority of objects were acquired during the 1970s. This timing proved fortuitous for the assembly of the university's collection, as museum-quality sacred works were available at fairly reasonable prices. The result for Rockhurst was a diverse collection of exemplary objects depicting religious subjects and/or with liturgical functions that date from the late medieval through the rococo periods. The works that comprise the collection are of Italian, German, Austrian, French, and Spanish provenance and their mediums range from lindenwood, polychromed wood, alabaster, and marble statues, to paintings rendered in tempera on wood panel and in oil on canvas and copper, as well as to works on paper, furniture, textiles,


Permutation Flow shop scheduling(PFSP) is a complex combinatorial optimization problem with strong engineering background,and is of great importance in both theory and application.In this paper,a new PSO based flow shop scheduling algorithm is proposed to generate optimized PFSP schedule.First,limitation of information sharing mechanism in GPSO model is analyzed and new population based information sharing strategy is proposed.PFSP scheduling algorithm based on new information sharing strategy utilizes problem-concerned knowledge to direct its search in the local search procedure.Compared with representative PFSP scheduling algorithms,the proposed algorithm can obtain good balance between quality of schedule and computational cost.Simulation results validate its efficiency.


The analysis of vulnerability in networks generally involves some questions about how the underlying graph is connected. One is naturally interested in studying the types of disruption in the network that maybe caused by failures of certain links or nodes. In terms of a graph, the concept of connectedness is used in dierent forms to study many of the measures of vulnerability. When certain vertices or edges of a connected graph are deleted, one wants to know whether the remaining graph is still connected, and if so, what its vertex - or edge - connectivity is. If on the other hand, the graph is disconnected, the determination of the number of its components or their orders is useful. Our purpose here is to describe and analyze the current status of the vulnerability measures, identify its more interesting variants, and suggesta most suitable measure of vulnerability.


The purpose of this article is to present pedagogical practices from the perspective of discourse and, from the Vol. 11 Número 22 Jul./Dez. 2016


The text intends to roam about Clarice Lispector's work, mimicking her women's roaming about the city. Throughout, in a kind of "bricolage", it brings together quotations as fratures of meaning which it produced in the relation among woman, city and poverty. By doing this, the essay attempts to illuminate one of the blind spots of criticism.


Modern economics is filled with models using simultaneous equations to explain economic behavior. One common model, the circular flow diagram, is found in many principles-level textbooks, and is offered as the basic way in which economies function. The entrepreneur, if included at all, is relegated to being a part of the box labeled "firms." Carl Menger argued, however, that economic behavior is best under- stood using the idea of cause and effect. Further, economic behavior is temporally directional. Thus, causation and time are missing in modern analyses, leading to a su- perficial role for the entrepreneur. This article uses the example of the entrepreneur to highlight Menger's method of cause and effect.


This paper considers practical, high-order methods for the iterative location of the roots of nonlinear equations, one at a time. Special attention is being paid to algorithms also applicable to multiple roots of initially known and unknown multiplicity. Efficient methods are presented in this note for the eva-luation of the multiplicity index of the root being sought. Also reviewed here are super-linear and super-cubic methods that converge contrarily or alternatingly, enabling us, not only to approach the root briskly and confidently but also to actually bound and bracket it as we progress.


Stellar activity observed as large surface spots, radio flares, or emission lines is often found in binary systems. UX Arietis exhibits these signs of activity, originating on the K0 subgiant primary component. Our aim is to resolve the binary, measure the orbital motion, and provide accurate stellar parameters such as masses and luminosities to aid in the interpretation of the observed phenomena. Using the CHARA six-telescope optical long-baseline array on Mount Wilson, California, we obtained amplitudes and phases of the interferometric visibility on baselines up to 330 m in length, resolving the two components of the binary. We reanalyzed archival Center for Astrophysics spectra to disentangle the binary component spectra and the spectrum of the third component, which was resolved by speckle interferometry. We also obtained new spectra with the Nordic Optical Telescope, and we present new photometric data that we use to model stellar surface spot locations. Both interferometric visibilities and spectroscopic radial velocities are modeled with a spotted primary stellar surface using the Wilson–Devinney code. We fit the orbital elements to the apparent orbit and radial velocity data to derive the distance (52.1 ± 0.8 pc) and stellar masses ( , ). The radius of the primary can be determined to be and that of the secondary to be . The equivalent spot coverage of the primary component was found to be 62% with an effective temperature 20% below that of the unspotted surface.

In a model of a connected network on random points in the plane, one expects that the mean length of the shortest route between vertices at distance r apart should grow only as O(r) as r!1, but this is not always easy to verify. We give a general sucient condition for such linearity, in the setting of a Poisson point process. In a L L square, dene a subnetwork GL to have the edges which are present regardless of the conguration


A series of Pd(II) complexes containing chiral diamine ligands were investigated as asymmetric catalysts for the rearrangement of allylic imidates to allyl amides. The best catalysts were cations obtained by dechlorination of dichloro[(S)-2-(isoindolinylmethyl)-N-methylpyrrolidine]palladium(II) (17) with silver salts in CH2Cl2. Catalyst 18 was studied thoroughly and shown by 1H NMR and X-ray crystallography analysis to be a C1 symmetric dimer (Figure 1). A series of related catalysts 22−27 having various counterions and anionic ligands were also prepared and studied as asymmetric catalysts for the rearrangement of allylic N-(4-trifluorophenyl)benzimidate 29 to allylic benzamide 30 (eq 4). Rearrangement of 29 in CH2Cl2 (48 h at 40 °C) in the presence of 5 mol % of 18 affords (−)-30 in 69% yield and 55% ee. Enantioselection is increased to 60% when an isomerically pure sample of 18 is employed. Chemical correlation of allylic benzamide 30 with (R)-norvaline established that (−)-30 has the R absolute configu...

Abstract: The concept of multi-dimensional coherent spectroscopy originated in nuclear magnetic resonance (NMR) where it revolutionized NMR studies of molecular structure and dynamics and led to the Nobel Prize in Chemistry in 1991. In the past decade, the same concept has been implemented in the optical region with femtosecond lasers. In this presentation, I will introduce optical multi-dimensional coherent spectroscopy and its applications to study a potassium (K) vapor and semiconductor nanostructures. The K vapor provides a simple test model to validate the method, while the obtained 2D spectra reveal the surprising collective resonance due to the dipole-dipole interaction in a dilute gas. By extending the technique into a third dimension, 3D spectra can unravel different pathways in a quantum process and provide complete and unambiguous information to construct the full Hamiltonian of the system.

In this paper, Web service discovery involves the service selection based on parameter-based service extraction and semantic similarity-based matching. In this approach, SWSRS is considered as the Web service Retrieval System. This approach assumes that the web service interfaces are defined in WSDL files. In this approach the similarity evaluation between the two interfaces are evaluated, higher the similarity less are the difference among their interfaces. This work based on the structure of WSDL and Semantic Web documents. The proposed approach incorporates with QOS requirements. However, earlier the QOS based non-functional requirement search has not been addressed. The lack of textual information makes keyword-based search models unable to filter irrelevant search results, and therefore, become very primitive means for effectively discovering web services. Therefore, the proposed approach i.e., SWSRS not only discussed the pertinent web service, it provides the services based on functional and QOS aspects. Index Terms – Web service discovery, information search and retrieval, WSDL, OWL, QOS .


Attempts to maintain prices different from those that would otherwise be determined by supply and demand are virtually guaranteed to result in illegal behaviour, including in the case of laws that determine the salaries of civil servants. In Indonesia, private sector salaries are highly progressive with respect to increasing levels of responsibility, whereas the civil service structure is very flat, resulting in an enormous gap between private and public sector salaries at higher levels of management. As a consequence, informal--and often illegal--income generating practices are observed that make public sector careers far more attractive than formal remuneration levels would suggest. It is argued here that it is unhelpful to view endemic corruption simply in terms of unprincipled behaviour. Rather, it is best understood in terms of institutional weakness in the form of continued reliance on entrenched personnel management practices from the Soeharto era that deliberately ignored market realities.


a fully-automated data acquisition system to collect a very large number of photon trajectories at high illumination intensities, and carried out a collective photon-by-photon analysis of the transitions between the folded and unfolded states using a maximum likelihood method (Chung et al., JPC A 2011). We determined a transition-path time of ~2 microseconds for a WW domain that folds in ~100 microseconds and an upper bound of ~15 microseconds for protein GB1 that folds in ~2 seconds. The transition-path times for the two proteins differ by less than 10-fold while the folding rates differ by a factor of 20,000. This result shows that a slow-folding protein can fold almost as fast as a fast-folding protein when folding actually occurs!


A simple method is described for the preconcentration and determination of some of the atmospheric chloroHuorocarbons by using the GC−QMS method.The halogenated hy(1ro− carbons in100ml of air sample were preconcentrated into1.7ml of cold trap by using helium stream an(l were injected into a GC column.The determination of F−11and F・12 was done by electron impact mo(1e of the GC・QMS method.Recovery of this method is 100%and the results of replicate determinations are in good agreement with each other within the analytical error.


Verbalization results from human pursuit of effective transmission of messages.Being more and more widely used,it is the product of human language evolution,also the inevitable phenomenon of human language to adjust to social development and rapid rhythm of life.With various types,verbalization is a way to realize conceptual grammatical metaphor.Verbalized metaphor makes English more expressive,concise,lively,and vigorous.


Phenolic compounds were extracted from the fruits of Morus nigra and Morus alba using methanol and acetone. The sugar-free extracts (SFEs) were prepared using Amberlite XAD-16 column chromatography. All of the SFEs exhibited antioxidant potential as determined by ABTS (0.75–1.25 mmol Trolox/g), DPPH (2,2-diphenyl-1-picrylhydrazyl) (EC50 from 48 μg/mL to 79 μg/mL), and reducing power assays. However, a stronger activity was noted for the SFEs obtained from Morus nigra fruits. These extracts also possessed the highest contents of total phenolics: 164 mg/g (methanolic SFE) and 173 mg/g (acetonic SFE). The presence of phenolic acids and flavonoids in the extracts was confirmed using HPLC method and chlorogenic acid and rutin were found as the dominant phenolic constituents in the SFEs.

Although such statements from Greene have tended to discourage serious critical consideration of his entertainments, if we overlook the perfunctory tone we can see the remark revealing his understanding that such formulaic literature as spy novels demands a special structure of narrative conventions not encountered in "serious" or, to use J.A. Cawelti's term, "mimetic" fiction-conventions which, as critics like Cawelti, Robert Warshow and Ralph Harper argue, both determine and are determined by the expectations readers bring to these works. Yet, despite his labelling Stamboul Train, The Confidential Agent, The Ministry of Fear and Our Man in Havana as entertainments, and authorial comments like the one quoted above notwithstanding, I shall argue that Greene deliberately sets out to challenge-if not frustrate-reader expectations by either departing from the basic conventions of the formulaic narrative world or else utilizing these conventions in such a way as to blur the line separating formulaic from mimetic fiction. I do not wish to suggest, however, that these entertainments are mere literary games in which a clever author plays with his readers' sensibilities. Like Conrad's The Secret Agent before them, Greene's thrillers represent a serious attempt to establish the spy novel as an appropriate vehicle for exploring the tensions, ambiguities, darkness and sense of alienation which characterize the experience of modernity in the twentieth century. The most significant feature of formulaic narratives-spy novels, westerns, gothic romances, science fiction fantasies, detective thrillers-as defined by Warshow is self-referentiality:


This paper proposes to investigate the interplay between time delay and external noise in explaining the behaviour of the microbial growth in batch fermentation process. Time delay and noise are modelled jointly via stochastic delay differential equations (SDDEs). The typical behaviour of cell concentration in batch fermentation process under this model is investigated. Milstein scheme is applied for solving this model numerically. Simulation results illustrate the effects of time delay and external noise in explaining the lag and stationary phases, respectively for the cell growth of fermentation process.


The facilitating motivational effect of feedback on performance has been attributed by some to difficult goals set in response to feedback. In this article, the effect was attributed to the presence of both a difficult goal and feedback about performance in relation to that goal. Eighty families were asked to set a goal to reduce their residential electricity consumption for several weeks during the summer, half of them by 20% (a difficult goal) and half by 2% (an easy goal). Within each of these groups, half of the families were given feedback three times a week about their consumption. Twenty more families served as a control. As predicted, the 20%-feedback group conserved the most (13.0% - 15.1%) and was the only one that consumed significantly less electricity than the control. It was concluded that improved performance was a result of the joint effect of feedback and goal setting. The implications of this research for a national residential conservation strategy are discussed. 20 references, 2 tables.


Abstract The prostrate thallus of Stigeoclonium was studied under defined culture conditions. The development from zoospore to adult stage was followed in detail with the result that no more than three morphological groups (or species) can be discerned. The three groups are designated as Stigeoclonium helveticum, S. tenue, and S. farctum. Considerable intra- and intergenotypic variation exists, especially in the erect system of Stigeoclonium helveticum and in the prostrate system of S. tenue. The prostrate system of Stigeoclonium farctum is not always a closed pseudoparenchymatous disc, but may form an open star-like 'variabile' habit.


A variety of surface water systems, including a lake, a creek, and two marine embayments, were analyzed on a monthly basis for indigenous human enteroviruses and coliform bacteria. Findings are discussed in terms of the probable pollution sources to each system and their relationship to data from previous studies.

Robertson Davies's Salterton trilogy, consisting of Tempest-Tost, Leaven of Malice, and A Mixture of Frailties , is united by a religious myth of achieved freedom and spiritual growth. This myth, buttressed by Shakespeare's The Tempest and Apuleius's The Golden Asse , is developed through explorations of longing, bondage, freedom, and love, and through the search for a social order in which the individual is fulfilled rather than stifled. The characters' personal growth, both singly and in sum, allegorizes Canada's own growth to spiritual and cultural maturity.


Aim. To study the efficacy of class IC arrhythmic drugs (AAD) and catheter ablation (CA) for paroxysmal form of atrial fibrillation (AF) in patients with without structural heart disease.Material and methods. The study included 122 patients (44 men, 78 women, mean age 63 [55;68] years) with symptomatic AF paroxysms. Patients was divided into the lappaconitine hydrobromide group (LH group; n=26), the propafenone group (P group; n=25) – 25 patients, the diethylaminopropionylethoxycarbonylaminophenothiazine hydrochloride (DH group; n=23), the CA groups: radiofrequency ablation (RFA group; n=24) and cryoballoon ablation (CRYO group; n=24) groups each included 24 patients. The primary endpoint was the AF recurrence within 6 and 12 months from the onset of antiarrhythmic drug therapyand in RFA and CRYO groups – within 6 and 12 months after the end of the blinding period. Additionally, in AAD groups a composite endpoint was assessed: the frequency of recurrence of AF within 6 months and the frequency of side effects requiring drug withdrawal.Results. Within the 6 months AF recurrence was observed in 13 (50%) patients of the LH group, 11 (44%) patients of the P group, and 13 (56.5%) patients of the DH group (p=0.687). Side effects requiring drug withdrawal were observed in the LH group in 2 patients (7.7%), in the P group in 3 patients (12%) and in the DH group in 3 patients (13%) (p=0.801). The difference in frequency of reaching the composite endpoint was not significant (p = 0.581) and the incidence was 57.7%, 56%, 69.5%, respectively in groups LH, P and DH. The efficacy of CA was higher than class IC AADs: 77% vs 39% (that including the withdrawals of AADs due to side effects) (p˂0.001). At the same time, there was no significant difference in the effectiveness of RFA and CRYO: AF recurrences within 6 months after the end of the blinding period were registered in the RFA group in 29% of cases, in the CRYO group – in 16.7% of cases (p=0.247). The overall effectiveness of CA after 12 months was 69%, which was significantly higher than the effectiveness of AADs that was 38% (p˂0.001).Conclusion. Starting the AAD therapy with IC class in patients with paroxysmal AF in the absence of structural pathology, despite acceptable safety, one should take into account that, regardless of the initially prescribed drug, less than half of patients can achieve prevention of AF recurrence within 1 year. CA for AF can be considered as a first line therapy or can be recommended if one of IC class AADs is ineffective.


Abstract When enslaved people became "mad," they lost exchange value as labor capital on the Atlantic market, as neither African nor European merchants considered the mentally distressed to be valuable bondsmen. Historians of slavery in the Americas have drawn on accounts of "mad slaves" to understand how labor value was generated, and disrupted, through the transport and sale of captive Africans. But historians have yet to examine the relationship between psychological distress and enslavement in West Africa, where many of the captives in question originated. This article opens a research agenda on madness in Atlantic-era West Africa through a case study of the role of Ga shrines as spaces of mental healing in eighteenth- and nineteenth-century Gold Coast, today's coastal Ghana. Ga families confided their mentally distressed kin to shrine priests, who treated severe illnesses caused by ritual afflictions. When shrine priests healed these ailments, they engaged in spiritual pawning: converting mad persons, deemed unfit for sale due to mental incapacity, into potential subjects of enslavement. West African shrines were thus spaces of value conversion that reflected a broader monetary and ritual economy of capture, enslavement, and raiding that proliferated on the Gold Coast.

The dramatic increase in the scale of current and planned high-end HPC systems is leading new challenges, such as the growing costs of data movement and IO, and the reduced mean times between failures (MTBF) of system components. In-situ workflows, i.e., executing the entire application workflows on the HPC system, have emerged as an attractive approach to address data-related challenges by moving computations closer to the data, and staging-based frameworks have been effectively used to support in-situ workflows at scale. However, the resilience of these staging-based solutions has not been addressed and they remain susceptible to expensive data failures. Furthermore, naive use of data resilience techniques such as n-way replication and erasure codes can impact latency and/or result in significant storage overheads. In this paper, we present CoREC, a scalable resilient in-memory data staging runtime for large-scale in-situ workflows. CoREC uses a novel hybrid approach that combines dynamic replication with erasure coding based on data access patterns. The paper also presents optimizations for load balancing and conflict avoiding encoding, and a low overhead, lazy data recovery scheme. We have implemented the CoREC runtime and have deployed with the DataSpaces staging service on Titan at ORNL, and present an experimental evaluation in the paper. The experiments demonstrate that CoREC can tolerate in-memory data failures while maintaining low latency and sustaining high overall storage efficiency at large scales.


The probability distribution of the interparticle distance is obtained for the N-body boson problem where the potential is an attractive delta function. This is done for both the exact wave function and the Hartree wave function allowing the calculation of the correlation hole.


We prove a new lower bound for the Mahler measure of a polynomial in one and in several variables that depends on the complex coefficients and the number of monomials. In one variable, our result generalizes a classical inequality of Mahler. In [Formula: see text] variables, our result depends on [Formula: see text] as an ordered group, and in general, our lower bound depends on the choice of ordering.


This research aims to investigate the relative importance of four aspects (Kinesics, Proxemics, Paralanguage, and Appearance) on the basis of two sub-factors - trust and customer satisfaction - of relationship quality, in determining customer"s positive word-of-mouth and revisit intention. In order to investigate the relationship, a survey was distributed to customers who have visited luxury hotels in Seoul, from April 4th to 20th, 2016. Total 350 questionnaires were handed out and 328 questionnaires were collected, of which 285 questionnaires were valid and used to run hypothesis test. The Path Analysis method was used to test hypothesis by applying AMOSS software, in order to find out the relationships among such variables as non-verbal communications, relationship quality, positive word-of-month, and revisit intention. This study found that the four factors (Kinesics, Proxemics, Paralanguage, and Appearance) of non-verbal communication in luxury hotel services have a significant relationship with trust and customer satisfaction, as well as a positive impact on word-of-mouth and revisit intention. This research emphasizes that 1) Appearance and Paralanguage have the most significant impact on the trust of relationship quality, while Proxemics has the most significant influence on customer satisfaction; 2) trust of relationship quality has greater influence on establishment of positive word-of-mouth effects, while customer satisfaction has the greater influence on hotel revisit intention in the future. Consequently, it is necessary for luxury hotels to consider the importance of non-verbal communications in order to efficiently establish customers" word-of-mouth and increase revisit intention by maintaining good relationship quality with customers. Implications and limitations of this study were also discussed.


The invention discloses a steel-support non-cohesive steel strand lower support type prestress floor reinforcing method. The method includes: two or one steel support is disposed at the one-third-span position or half-span position of the bottom of a floor to change the single-span floor into a three-span floor or a two-span floor; certain-distance three-folding-line-shaped or two-folding-line-shaped non-cohesive steel strands are disposed at the bottom of each steel support to serve as the support points of the steel support; two ends of the non-cohesive steel strands are fixed on floor beams or ring beams through steel base plates and anchoring tools; after the non-cohesive steel strands apply prestress, upward counterforce is generated at each steel support to balance off part of floor load so as to achieve the reinforcing effect. The method has the advantages that the steel supports can be made of small I-shaped steel, and brackets at two ends of the steel supports are not needed; the method is an active reinforcing method, the stress of the reinforcing steel bars in the floor becomes small with the application of the prestress, the original cracks of the floor can be reduced and effective controlled, and floor deflection is reduced.

Meeting the translational challenge presented by complex diseases and datasets requires the use of computer-augmented, high-throughput hypothesis evaluation within an evolutionary paradigm for the propagation of biomedical knowledge. Advances in computing capability offer the biomedical research community the prospect of creating simulations at a previously unimaginable scale. A diagnostic analysis of the underpinnings of the translational dilemma suggests that the current high-throughput, data-rich research environment has led to an imbalance in the relationship between determinations of correlation and the evaluation of causality. Here I describe the use of high-performance computing technologies to facilitate high-throughput hypothesis evaluation combined with an evolutionary paradigm for the advancement of scientific knowledge. This combination provides a roadmap for closing the scientific loop between correlation and causality, a necessary step if translational endeavors are to succeed.

This study is aimed at determining selected liver enzymes functions effect of Raphia Hookeri fruits pulp extract in male wistar rats. A total of 32 apparently healthy rats of weights between 130g and 200g were involved. The rats were segregated into 4 groups, 3 groups administered orally with doses of extract at 500mg/kg, 1000mg/kg and 2000mg/kg body weight while control group fed with feed and water for 28 days. The animals were sacrificed, samples taken, laboratory test done for liver enzymes functions. SPSS version 21.0 (ANOVA) followed by Post-Hoc multiple comparison test used and p< 0.05, values were expressed as SEM for statistical analysis. Results showed AST level of groups 3 and 4 had significant decreases when compared to control and 500mg/kg group respectively. AST level of group 4 was significantly lower compared to that of group 3. ALT level indicated non-significant changes in treated groups when compared to both control and test groups. The ALP levels in groups 2 and 3 showed significantly raised levels of ALP when compared to that of control had significantly reduced level of ALP compared to that of group 2. Increased AST an indication to measure serum ALT to determine whether the increased AST is from liver Willard & twedt, 2012. So the decreased level AST has demonstrated ameliorative effect of the raphia hookeri fruit pulp on hepatic disease and any other disease that causes an increase AST in the body. Regular consumption of this fruit is recommended for those with liver issues.


In this paper, BaZrO3, which is successfully used to prepare the YBCO single crystal superconductor, is introduced into the melting of titanium alloys. The density of the home-made BaZrO3 crucible reaches 97% of theoretical density, and TiNi alloy is melted using this crucible by the vacuum induction method. It is found that the home-made BaZrO3 crucible possesses excellent thermal shock resistance. After melting, the surface of the ingot is smooth and it can be separated from the crucible easily, there is no reaction layer and elemental diffusion between the refractory and the melt is not observed, the oxygen content of the melt is about 600 ppm, and the increase of other impurity elements (i.e., Ba, Zr) is negligible. This implies that the BaZrO3 is a promising candidate for refractories for melting the TiNi alloy.


The article deploys Bauman's metaphor of the 'gardening' state to consider the imbrication of planning and the dark side of modernity. It interrogates the public production and defence of urban spaces suitable for people deemed to have value. Using empirical material from urban Zimbabwe, I frame planning as a spatial technology of the gardening state and peer into its handling of informality under two main themes: first, the perception, construction and designation of 'weeds', and second, the declaration and treatment of the 'weeds'. Situating Bauman's metaphor in the nexus between planning, the state and informality, I conclude that the metaphor paints a helpful but inadequate picture. I argue that while the metaphor is helpful with regards to the first theme, refinements are needed in its application to the second. Rather than see planning enforcement as a rational-scientific practice, a nuanced conceptualisation is needed that explicitly acknowledges the messy business of politics.

To sustain in business under the current global situation of fierce competition a company needs to reduce or eliminate the idle and/or down time of operations in addition to improvement of the current working methods. In this case study, the problems and challenges of an auto company engaged in assembling car rear window assembly are attributable to non-optimal operations with inefficient capacity planning. The whole assembly line suffers due to the absence of established standard time for activities carried out by operators, the non-value added activities involved and the inefficient methods such as manual screwing, unplanned aisle and walking distance, material wastages and imbalance in the material flow. This study is conducted through application of Maynard Operation Sequence Technique (MOST) in the rear window assembly section to capture the workflow activities using systematic and descriptive workflow data block for the value adding, value engineering and methods engineering analysis. Subsequently, new methods and work standards are developed in advance for capacity planning, workplace layout design and manning analysis. Thus through the process redesign and process flow analysis, material handling and workflow are improved. Consequently, it has been possible to reduce the production cycle time to cater the higher level of demand with shorter takt time maintaining the current level of manpower.

Conventional downhole tubing often fails due to sweet corrosion, sour corrosion or microbiologically influenced corrosion (MIC). Important factors that lead to corrosion are the presence of carbon dioxide (CO2), hydrogen sulfide (H2S) and varying levels of water cut. These types of corrosion lead to failures requiring workovers, as well as production loss and tubing replacement. Composite lined carbon steel tubing can be a great alternative to corrosion resistant alloys (CRAs) for downhole applications, which will cost effectively ensure a longer service life. Composite lined carbon steel tubing consists of a thin wall of a fiber reinforced polymer (FRP) liner inserted into the steel tubing. The thin liner only acts as a corrosion barrier while the pressure loads are carried by the host carbon steel pipe. This article is a two-part discussion illustrating the composite lined tubing as oil field tubular goods for downhole application. The article first focuses on the design and prequalification of the composite lined tubular system. Second, the field trial of composite lined carbon steel tubing in a Saudi Aramco facility is presented. The objective for the development of these prequalification criteria was to select the proper liner and avoid any unexpected failure during the service period. On the other hand, the field trial that began before the design and prequalification premises were developed showed that the tubing did not display any functional degradation since it was deployed in 2002 in an offshore downhole application. Consequently, the investigation confirmed that major cost avoidance was realized as the production tubing system can run for an extended period of time without maintenance and/or a need for replacement.


Abstract This article wants to introduce a possible definition of Public Archaeology and its adaptation to the Peruvian context based on concepts published by other specialists as well as the theoretical orientations concerning archaeological heritage management in Peru. Upon this observation, this article intends to call archaeologists' attention to the study of the general public, aiming to improve the archaeologist-public relationship.


Background One of the most prevalent clinical phenotype of osteoarthritis (OA) is hand OA (HOA), which in some patients can evolve to erosive HOA. In erosive HOA central erosions and subchondral destruction are seen, and imaging studies have indicated that in erosive HOA hand joints display more inflammatory signs than in non-erosive HOA. Autoantibodies directed against post-translationally modified proteins, such as citrullinated (ACPA) and carbamylated (anti-CarP antibodies) proteins, are a hallmark of rheumatoid arthritis (RA), and are associated with more severe joint damage and inflammation. Interestingly, these antibodies are present in a small subset of SLE patients as well, in which they associate with bone erosions. This suggests the possible involvement of autoantibodies in inflammation and joint damage in other conditions than RA. Therefore, we hypothesised that autoantibodies are present in HOA and associate with erosive disease. Objectives To investigate whether three RA-associated antibodies, Rheumatoid Factor (RF), ACPA and anti-CarP antibodies, are present in hand OA and associate with erosive OA. Methods Anti-CarP IgG, ACPA IgG and RF IgM were measured by ELISA in baseline sera of HOA patients from 3 cohorts: HOSTAS (n=510, mean age 61.0 years, 85.7% women, 27.2% EOA), ECHO (n=47, mean age 63.4 years, 89.4% women) and EHOA (n=23, mean age 57.1 years, 73.9% women), and in sera of healthy controls (HC; n=196, mean age 44.1 years, 51.0% women). The prevalence of autoantibodies was compared between HOA and HC and between erosive and non-erosive HOA. In HOSTAS, hand radiographs were scored (Kellgren-Lawrence, OARSI osteophyte and joint space narrowing scores) and C-reactive protein (CRP) levels, representing inflammation, were assessed. Groups were compared using non-parametric tests. Results In both ECHO and EHOA cohorts, only one patient was positive for RF IgM and none were positive for ACPA IgG. In all three cohorts, a low prevalence of anti-CarP IgG was detected and this was not different between HOA patients and HC (6.6% vs 3.6%, p=0.12). Moreover, in HOSTAS, the prevalence of all tested autoantibodies was low and not significantly different from HC (anti-CarP 7.1% vs 3.6%, p=0.08; ACPA 0.8% vs 1.5%, p=0.37; RF 6.1% vs 4.1%, p=0.30). Likewise, no difference was found between erosive and non-erosive HOA (anti-CarP 7.2% vs 7.1%, p=0.94; ACPA 0.7% vs 0.8%, p=0.92; RF 4.3% vs 6.5%, p=0.36). Radiographic damage and CRP levels were similar in anti-CarP positive vs negative, and RF positive vs negative HOSTAS patients. Conclusions The prevalence of autoantibodies is similar in HOA patients and healthy controls. Moreover, these autoantibodies are not associated with erosive disease, structural damage or inflammation in HOA patients, indicating that another mechanism is driving erosive disease.

We consider the N = 1 supersymmetric Korteweg–de Vries (sKdV) equation within the framework of Hirota's bilinear method. We construct a Bäcklund transformation which may be interpreted as the modified sKdV equation. Also, we find a Lax representation and a nonlinear superposition formula. By direct applications of the nonlinear superposition formula, we calculate soliton solutions for the sKdV equation.


. All spaces are metrizable. A conjecture of de Groot states that a weak inductive dimension theory beginning with the class of compact spaces will characterize those spaces which can be extended to a compact space by the adjunction of a set of dimension not exceeding zi. Nagata has proposed a variant of this conjecture as a means of finding insights into the original conjecture. (See Internat. Sympos. on Extension Theory, Berlin, 1967, pp. 157—161.) The proposed variant replaces compact with 0"-compact. The present paper concerns a study of strong inductive dimension theory beginning with an arbitrary class of spaces. The study is motivated by the above two conjectures. It indicates that a theory of kernels is a more natural by-product of inductive theory than a theory of extensions. An example has resulted which, with the aid of the developed theory and the Baire category theorem, resolves the second conjecture in the negative. The original conjecture is still unresolved. It is also shown that the notion of kernels results in a further generalization of Lelek's form of the dimension lowering map theorem (Colloq. Math. 12 (1964), 221-227


Context: This paper investigates the integration of research project objectives into student projects. The main research project aimed to develop a novel piece of equipment to address a serious social issue. Substandard housing causes respiratory ill-health that disproportionately impacts on low income individuals. This is of particular significance to the Institute involved in the research project. The main project aimed to understand the indoor air quality features of the destination environments for a climate control and air-purification device and model the proposed design of the device in these environments. Purpose: To generate student projects that effectively inform tasks on a main project, and enable students to participate in the development of a solution to a problem that affects their community. Approach: This paper contains a reflection on the mapping of project requirements to learning outcomes of the project paper. Summary information on student performance is provided. The service outcome of student work is examined, and potential for the project to be adapted to meet service learning objectives is presented. Results: Student projects supported the objectives of the main project, but solutions tended to lack novelty. Mapping the main project's requirements to the student projects' learning outcomes occurred naturally. Students were able to participate in service to their community through the projects. Conclusions: Allowing students to contribute in a small way to more than one module of a project provided for a broader experience, and enhanced development of multiple skills, including soft-skills. Because the main project involved a service component, student projects may be adjusted in future to contain a service learning element.


Increase of wear resistance of different types of tribomating which are functioning in fluid lubrication is possible due to: choosing more expensive and high quality material of samples that is not always sensible; applying some wear resistant coatings on them; selection and formation of complex composition of oil additives. Due to nanomaterials development there is a possibility of efficient use of functional additives such as geo modifiers in tribology. Due to geo modifier-based oil composites use it's not necessary to make any structural changes of machines mated parts though their wear resistance is increased. It requires the conducting of some experimental tribological research. It was found that oil media modified by a geo modifier increase the wear resistance of working surfaces of different types of tribomating. The use of geo modifier КGМF-1 (Katerynivka friction geo modifier-1) has been suggested. Samples division into 4 types of mating according to the following characteristic features: mobility, material hardness and friction area has been suggested for more accurate picture of wear resistance changes of samples tribomating which are functioning in base and modified oil. Lower friction torque of different samples couplings in modified oil by geo modifier КGМF-1 in comparison with base oil M-10G2K was recorded while using Friction machine 2070 SMT-1 with add-on module "ring-ring". The samples wear rate in modified oil by geo modifier КGМF-1 in comparison with base oil M-10G2K was studied by method of acoustic signal amplitude measurements directly from the friction zone by a commercially produced instrument of Brüel & Kjear company. Moreover, it was recorded that the maximum wear rate of samples in their functioning in modified oil M-10G2K + КGМF-1 was 2...3 times lower, and friction torque change law is similar to the wear rate change depending on the time of testing.


The HRM sphere experiences new ideas and concepts everyday due to growing labour supply and benchmarking. Moonlighting is a topic that is gaining momentum for research in India, even though moonlighting as such is not a new concept in India.  The present study is conducted as a pilot study which tried to explore the demographic profile of the moonlighting teachers in Kanchipuram district and the factors influencing their moonlighting intention. A questionnaire was circulated among 75 teaching faculty. The study found that the Financial needs play dominant role in determining moonlighting intentions of teachers.


The β4‐and β10‐thymosins, recently identified as actin monomer‐sequestering proteins, are developmentally regulated in brain. Using specific mRNA and protein probes, we have used in situ hybridization and immunohis‐tochemical techniques to investigate the distribution of the β‐thymosin mRNAs and their proteins in developing rat cerebellum. Early in postnatal development, both β‐thymosin mRNAs were expressed at highest levels in the postmitotic, premigratory granule cells of the external granular layer; expression diminished as granule cells migrated to and differentiated within the developing internal granular layer. In addition, both β‐thymosin proteins were present in bundles of cerebellar afferent fibers in the white matter at this time. Throughout the maturation period, both proteins were present in elongating parallel fibers in the upper portion of the molecular layer. Later in cerebellar development, thymosin β4, but not thymosin β10, was expressed in Golgi epithelial cells and Bergmann processes. Thymosin β4 was expressed in a small population of cells with microglial morphology scattered throughout the gray and white matter. Thymosin β10 was detected in an even smaller population of glia. Expression of thymosin β4 and thymosin β10 in premigratory granule cells and in growing neuronal processes is consistent with the possibility that both β‐thymosins are involved in the dynamics of actin polymerization during migration and process extension of neurons.


A study has been conducted on the isolation and identification of secondary metabolite compounds from methorol extract of kelor leaf (Moringa oleifera Lamk.). This study aims to isolate and identify secondary metabolite compounds from leaf kelur methanol extract. Moringa leaf was macerated with methanol and obtained a yield of 16.7% methanol extract. The extract of methanol separated by column chromatography yielded 272 fractions. The fraction was purified and analyzed by thin layer chromatography using eluent n-hexane: ethyl acetate (7: 3) and obtained stain spots with Rf (0.61) and (0.47). Phytochemical results of positive isolates on flavonoids test. The results of identification using UV-Vis spectrophotometry and infrared spectrophotometry is a flavonoid compound. The identification using UV-Vis spectrophotometry yields I absorbing bands at 250 nm wavelength. The absorption at 250 nm wavelength is suspected because of the non-bonding electron transition to the σ anti-bonding orbital (n → σ *) by an unconjugated ausochrome suspected to be a hydroxyl functional (OH) group. Identification using infrared (IR) spectrophotometry showed the presence of a bound OH function group, C = O, C = C aromatic, C-H aliphatic, C -O alcohol and = C-H aromatic.


This paper deals with a phase microscopy study on the effects of podophyllin on the tumor cells of the MTK-sarcoma III. The changes of tumor cells in response to exposure to the drug were followed in single cells with the utilization of the hanging-drop preparation made in combination of fluid paraffin and podophyllin.It was shown that podophyllin damaged the cells as a whole and exerted a visible influence on the cytoplasm. The cells were damaged by blebbing and vacuolization of the cytoplasm, followed by a pycnotic degeneration of the nucleus, or of the chromosomes.


Impacts to four sites near drill hole U20bc on Pahute Mesa in the northwestern part of the Nevada Test Site were mitigated through data recovery. The work was done during 1988 by the Desert Research Institute for the Department of Energy, Nevada Field Office (DOE/NV)- The four sites that warranted data recovery were 26NY3171, 26NY3173, 26NY5561 and 26NY5566. These sites had previously been determined eligible to the National Register of Historic Places. They were temporary camps that contained lithic debitage, projectile points, milling stones and pottery, and therefore contributed significant information concerning the prehistory of the area. The study of the archaeological remains shows that the prehistoric people subsisted on plant foods and game animals as determined by the artifacts including manos, metates, pottery, lithic scrapers, and projectile points. The time sensitive arfifacts (pottery and diagnostic points) suggest that the region was used from about 12,000 B.P. to just before the historic period, possibly 150 years ago. DOE/NV has met its obligation to mitigate adverse impacts to the cultural resources at U20bc. Therefore, it is recommended that this project proceed as planned.


Canada's program to eliminate tuberculosis from its livestock has met with great success. Administration of the program has at times presented difficulties, but these were of minor significance in terms of the overall results. Today. we only uncover tuberculosis in Canadian cattle on rare occasions, even though the level of infection in some parts of Canada was once as high as 25 per cent. The first Canadian testing of bovine livestock for tuberculosis dates back to 1897, when tuberculosis testing was offered to livestock owners free of charge on a request basis. There were no restrictions on disposal of reactors, nor were these reactors identified. Soon after, in 1905, the Supervised Herd Plan was introduced. Although this program was also voluntary, reactors were identified and had to be removed from the herd. In 1907 a national meat inspection system was introduced into Canada, via legislation known today as the Meat Inspection Act. This system produced reliable statistics on the incidence of tuberculosis in animals slaughtered under inspection. This, 'in turn, provided the impetus for development of programs aimed at control and eradication of the disease. The next phase in the history of our program began in 1914 with passage of the

Twenty-four consecutive episodes of atrial flutter in 20 patients were treated with overdrive atrial pacing after a pre-treatment with oral Amiodarone. This technique was effective in interrupting the arrhythmia in 23 instances (95,8%). Normal sinus rhythm was restored in 22 cases: in 18 of then (75%) it appeared immediately at the end of stimulation and in 4 after a short intervening period of atrial fibrillation. In accordance with the experience of other authors, the combined pharmacological and electrical treatment provides a higher rate of conversion of atrial flutter into normal sinus rhythm and a lower rate of early relapses of the arrhythmia.

In the first of T. S. Eliot's Four Quartets, 'Burnt Norton,' appear the following lines: Quick, said the bird, find them, find them, Round the corner. Through the first gate, Into our first world, shall we follow The deception of the thrush? Into our first world. …………… Go, said the bird, for the leaves were full of children, Hidden excitedly, containing laughter. Eliot returns to the image of the garden and the children in the last of this cycle, 'Little Gidding': Through the unknown, remembered gate When the last of earth left to discover Is that which was the beginning; At the source of the longest river The voice of the hidden waterfall And the children in the apple-tree Not known, because not looked for But heard, half heard, in the stillness… All manner of thing shall be well When the tongues of flame are in-folded Into the crowned knot of fire And the fire and the rose are one.


The technological grain quality traits of varieties of the Federal Scientific Rice Centre (Rapan., Rapan 2, Favorit, Nautilus, Yakhont, Olimp, Patriot) grown in the old-delta and valley agrolandscape zones of Krasnodar region (Russia) in 2017–2019 were studied. The studied rice varieties are included in the State register of breeding achievements approved for use in the North Caucasus region in 2014-2019, Rapan 2 is under state variety testing. Most of the varieties under study showed the highest values of grain quality traits in the valley agrolandscape in 2019, in the old-delta - in 2018, which indicates the reaction of the varieties to agroclimatic conditions of vegetation. The best varieties for grain quality on the basis of low variability in the aggregate of all quality traits were recognized as Favorit for the valley agrolandscape zone of Krasnodar region (predecessor – fallow field), and Rapan 2 for the old delta agrolandscape zone (predecessor - winter wheat). According to the absolute values of the traits characterizing the yield and milled rice quality, the best variety in the valley agrolandscape was Yakhont, and in the old-delta, Nautilus. The placement of rice varieties in agrolandscape zones of Krasnodar region is recommended taking into account their reaction to agroclimatic conditions of cultivation.


The effect of open orbits on helicon propagation is investigated theoretically and experimentally. At the high field limit, the damping of helicons is found to be very sensitive to the amount of open orbit current, whereas the dispersion is only slightly affected. The low rf surface impedance of a copper single crystal is measured at 4.2°K in a magnetic field up to 55 kG. The field direction is oriented along or within a few degrees of the [001] axis. The result is compared with the calculated rf susceptibility based on the knowledge of several known open orbits. The standing wave pattern is observed when B is parallel to the [001] axis. The ``effective Hall coefficient'' obtained from the dispersion relation agrees with other dc measurements. The attenuation when B tilts away from the [001] axis is interpreted to be the damping effect caused by the two‐dimensional open orbit current. The average damping effect is smaller than that calculated from open orbits of known order.


The effect of external periodic driving forces in the tunneling process of a two-level system is studied within the Floquet formalism and perturbation theory. Coherent tunneling can be increased or decreased depending on the external force parameters. In particular, the model is able to account accurately for the tunneling suppression phenomenon recently discovered


This paper describes speed control of separately excited DC motor (SEDM) adopting Chopper converter and PI as speed and current controller. The chopper firing circuit receives signal from controller and then chopper gives variable voltage to the armature of the motor for achieving desired speed. There are two control loops, the first for controlling current and the other one for speed. Modeling of separately excited DC motor is done. The complete layout of DC drive mechanism is obtained. The designing of current and speed controller is carried out. The optimization of speed controller is done using modulus hugging approach, in order to get stable and fast control of DC motor. After obtaining the complete model of DC drive system, the model is simulated using (MATLAB/SIMULINK).The simulation of DC motor drive is done and analyzed under varying speed with load torque conditions like rated speed and load torque, half the rated load torque and speed, step speed and load torque and stair case load torque and speed.

We introduce a class of sequencing problems based on some common, easily verifiable properties. Some well known members of this class are the Total weighted completion time problem and the Least cost fault detection problem, both with general precedence constraints. We present an efficient algorithm for solving these problems. It decomposes the original problem into smaller sub problems, called job-modules and sequences these in an optim al w ay. The main result of this paper is a polynomial-time algorithm for finding job modules in a general precedence graph.

AbstractRealistic truss design optimization problems are often governed by practical constraints. Because of the complexity of these constraints, usually only member constraints are taken into account during the optimization, and joint constraints are accounted for in a manual postprocessing step. This paper proposes a method to account for joint constraints in the global discrete size optimization of a steel truss structure. The design of an N-type truss girder is considered first without and then with the joint constraints specified in the Eurocode. To guarantee global optimality in both cases, the optimization problem is reformulated as a mixed-integer linear program. A statically determinate analysis model is adopted so as to ensure that all joint constraints can be reformulated as linear functions. If the joint constraints are not considered in the optimization, a design is obtained where the joints need additional strengthening. This can be done by manually selecting heavier sections, which often le...


The paper describes thefield ambient vibration testing on a prestressed concrete continuous box-girders,named Yongyang canal super bridge.The operational modal analysis(OMA) based on the frequency and spatial domain decomposition(FSDD) were used in the output-only data model identification,and the dynamic characteristics(natural frequencies and mode shapes) of the bridge were got.The complete three-dimensionalfinite element model of the bridge was established and updated based on the above results using genetic algorithm.The baseline-nite element model of the bridge were provided,which reflects the dynamic behaviors of the bridge structure and can serve as a baseline in the long-term health monitoring,condition evaluation and damage identication of the bridge in service.


In earlier studies1 we were unable to separate Nephritic Factor (Nef) from IgG by a variety of immunochemical techniques, indicating that Nef shares antigenic determinants with IgG. Purified Nef was found to bind to Protein-A-Sepharose, and could be eluted with acid. This binding was complete in three samples of Nef from patients with PLD or MPGN, but only partial in the fourth.
 We have now investigated the effects of pepsin and papain digestion on Nef structure and activity. Digestion of Nef with pepsin caused virtually no loss of activity. Before pepsin digestion this Nef preparation bound completely to Protein-A-Sepharose. After pepsin treatment 40 to 65% of the Nef was now recovered in the breakthrough peak and only 7% was eluted in the acid eluate. Digestion of Nef with papain caused some loss of activity. Approximately 30 to 80% of the activity was recovered.


There are different attitudes against criminal fine exchanged penalty system among theory circle of criminal law.Many countries have introduced this system in legislation.Although China has not set up,in recent years,there have been some cases of criminal fine exchanged penalty in judicial practice.Taken these practices under the existing legal framework they not only violate the principle of crimes and punishments stipulated by law and the principles of equality before the law,but also violate property rights of the state,confuse the methods of bearing liability and hinder the function of penalty.The judicial organs should not be allowed to put criminal fine exchanged penalty into practice before the system established in our criminal law.


The utility model relates to a hydraulic bracket, upright post and guide sleeve assembly mechanism. The mechanism comprises a base and a frame vertically arranged on the base and connected with the base through a hinge structure, wherein the frame is provided with a vertical lifting cylinder and a motor for installing an upright post and a guide sleeve and in fit connection with the lifting cylinder, a chuck is arranged below the motor, and at least one group of springs are arranged between the motor and the chuck. Because a swing arm type structure is adopted and the guide sleeve is vertically arranged, a sealing ring is prevented from being crushed by the dead weight of the upright post; meanwhile, the motor is in a floating structure, so the non-concentricity problem of the motor and the upright post is solved; and moreover, the structure of two springs is adopted, so the threaded axial displacement compensation problem of the guide sleeve is solved, and the axial abrasion is avoided. Therefore, the assembly mechanism controls the pre-pressure magnitude of the guide sleeve, and can effectively protect the guide sleeve from being crushed.


An electrodeposition of an iron-manganese alloy was made from the same conditions determined by previous research. Various addition agents were experimented with in an attempt to produce better conditions for e'lectrodeposition. It was found advantageous to add small amounts of sodium lauryl sulfate and ammonium sulfite to the electrolyte. Further experimentation revealed that the use of an insoluble anode and increased distances between the electrodes produced undesirable results.


A financial analysis of rubber (Hevea brasiliensis) plantation was made in February 2003 to determine economic profitability of rubber monoculture and rubber-agroforestry system in a rubber plantation of Sherpur district of Bangladesh. Rubber was intercropped with ginger (Zingiber officinale), turmeric (Curcuma longa), paddy (Oryza sativa), eggplant (Solanum melongena), different types of vegetables and fruits. Output was calculated on the basis of present market price. Financial indicators used were Net Present Value (NPV), Internal Rate of Return (IRR) and Benefit-Cost Ratio (BCR).  Level of profit was determined at the 15th year of the economic life of the plantings while average profit was increasing. Using 6% nominal interest rate NPV was found to be Taka 57751 for rubber-agroforestry and Taka -78043 (negative) for monoculture of rubber, IRR was 9% for rubber-agroforestry and -12% (negative) for monoculture and BCR was 1.43 for rubber-agroforestry and 0.22 for monoculture. Higher profit in rubber plantation can be achieved by practicing agroforestry. Agroforestry practice in rubber gardens has great potential in terms of profitability and enhanced environmental amelioration.


Cell Biology
In contrast to plants and fungi, animals can deform their bodies by the collective activity of contractile cells. Collective contractility underlies processes such as gastrulation and muscle-based motility. Brunet et al. report that a close relative of animals, a choanoflagellate they name Choanoeca flexa , forms cup-shaped colonies that undergo collective contractility, leading to a rapid change in colony morphology (see the Perspective by Tomancak). C. flexa colonies are each composed of a monolayer of polarized cells. In response to sudden darkness, a light-sensing protein triggers coordinated, polarized contraction of C. flexa cells, which results in colony inversion. The cellular mechanisms underlying this process are conserved between C. flexa and animals, indicating that their last common ancestor was also capable of polarized cell contraction.

Effects of setbacks on the earthquake response of multistory building structures are evaluated. As part of the study, measured responses to simulated earthquakes of a ductile moment‐resisting reinforced concrete test structure are examined. The test structure is a one‐quarter scale model of a six‐story, two‐bay by two‐bay building having a 50% setback at midheight. Experimental observations are supplemented with a series of analytical studies. Guidelines are established by which to detect configurations for which concentrations of damage in tower members are likely. A static lateral‐load design method to improve performance is proposed.

Tibial defect is very common musculoskeletal disorder which makes patient painful and uncomfortable. Many studies about bone regeneration tried to figure out fast bone healing on early phase. It is already known that low level laser therapy (LLLT) is very convenient and good for beginning of bone disorder. However, light scattering and absorption obstruct musculoskeletal therapy which need optimal photon energy delivery. This study has used an interstitial laser probe (ILP) to overcome the limitations of light penetration depth and scattering. Animals (mouse, C57BL/6) were divided into three groups: laser treated test group 1 (660 nm; power 10 mW; total energy 5 J) and test group 2 (660 nm; power 20 mW; total energy 10 J); and untreated control group. All animals were taken surgical operation to make tibial defect on right crest of tibia. The test groups were treated every 48 hours with ILP. Bone volume and X-ray attenuation coefficient were measured on 0, 14th and 28th day with u-CT after treatment and were used to evaluate effect of LLLT. Results show that bone volume of test groups has been improved more than control group. X-ray attenuation coefficients of each groups have slightly different. The results suggest that LLLT combined with ILP may affect on early phase of bone regeneration and may be used in various musculoskeletal disease in deep tissue layer.


In 15%-20% of children with severe combined immunodeficiency (SCID), the underlying defect is adenosine deaminase (ADA) deficiency. The overall goal of our research has been to identify the precise molecular defects in patients with ADA-deficient SCID. In this study, we focused on a patient whom we found to have normal sized ADA mRNA by Northern analysis and an intact ADA structural gene by Southern analysis. By cloning and sequencing this patient's ADA cDNA, we found a C-to-T point mutation in exon 11. This resulted in the amino acid substitution of a valine for an alanine at position 329 of the ADA protein. Sequence analysis revealed that this mutation created a new BalI restriction site. Using Southern analyses, we were able to directly screen individuals to determine the frequency of this mutation. By combining data on eight families followed at our institution with data on five other families reported in the literature, we established that five of 13 patients (seven of 22 alleles) with known or suspected point mutations have this defect. This mutation was found to be associated with three different ADA haplotypes. This argues against a founder effect and suggests that the mutation is very old. In summary, a conservative amino acid substitution is found in a high proportion of patients with ADA deficiency; this can easily be detected by Southern analysis.


Customers' perceptions of value have a direct impact on their overall experience and behavioral intentions of purchasing a product. Analyzing customers' intentions and motivations behind their food service experiences can shed light on the factors that influence their decision to visit specific establishments, their likelihood of revisiting, and their willingness to recommend the place to others. The purpose of this study was to explore the characteristics of food servicing and how it could influence customers to purchase accommodation. This study employed qualitative analysis to explore the experiences of customers in availing an accommodation. Customers (n=32) were interviewed about their experiences seeking information on which characteristics served as purchasing deal-breakers for them. The findings reveal that customers prioritize high-quality and appealing food products and menu offerings (healthy, local food), service quality (attitudes and behavior of the service crew), area (overall atmosphere, furniture), and pricing (discounts, low price points). These characteristics could influence their purchasing intention for an accommodation highlighting the need to meet the expectations and individual needs of the customers. These priority food servicing characteristics highlight the potential of food tourism within accommodation establishments. Understanding and addressing these factors can significantly impact consumer purchase behavior and attract more customers to the accommodation industry.


Range fires on the Hanford Site can have a long lasting effect on native plant communities. Wind erosion following removal of protective vegetation from fragile soils compound the damaging effect of fires. Dust storms caused by erosion create health and safety hazards to personnel, and damage facilities and equipment. The Integrated Biological Control Program (IBC) revegetates burned areas to control erosion and consequent dust. Use of native, perennial vegetation in revegetation moves the resulting plant community away from fire-prone annual weeds, and toward the native shrub-steppe that is much less likely to burn in the future. Over the past 10 years, IBC has revegetated major fire areas with good success. IBC staff is monitoring the success of these efforts, and using lessons learned to improve future efforts.


The stories of human creation in the biblical book of Genesis seem to place humanity at the heart of creation, but they can be and have been read in much more interesting ways. On many late ancient and medieval readings of creation, the body of a first human can be hard to tell from the body of everything else in the world, at times including god. This chapter draws on rabbinic, gnostic, and kabbalistic texts. It examines several points in the Jewish and Christian versions of these stories that displace the human from any central position, and often problematize the very notion of a center. These include the stories of a human drawn from the dust of the whole world, with the dust sometimes participating in the decision to create humans; stories of human as microcosm, where the boundaries of the cosmos turn out to be unstable; and stories of the divine light that both illuminates and conceals, sees and is seen, and wraps around and glows within worlds and bodies.

of a speech by De Gaulle communicative, apparently because of the transposition and substitution of certain phrases (p. 44). But the translation does not pass the test of equivalent effect; it is, in fact, simply a poor translation. Newmark's alternative translation is a fine example of combined semantic and communicative translation, even though he labels his own semantic. There seems to be an underlying assumption that good literature is a work of art and should be respected as such by the translator. In a sense, an artist communicates with himself, while we observe as outsiders. However, the degree to which any work of art communicates with others is what determines its acceptability. To ignore the communicative aspect of translation in favor of the purely semantic would not necessarily do justice to the writer as an artist. The author's rich experience appears to have been chiefly within the Indo-European family of languages. A heavier exposure to families with radically differing systems of morphology and syntax would have decreased Newmark's faith in the possibility of retaining artistic forms in translation. Problems such as these do not detract from the value and importance of this volume. The practical application of his principles and procedures will aid any translator in improving the product. And the theoretician and trainer will have various sets of parameters for examining and analyzing texts and translation, to say nothing of the honing effect on one's own ideas.

We propose a kinematic method for precisely measuring the top quark mass $m_t$ in $pp$ collisions using boosted top jets with light soft drop grooming. Light grooming retains a universal description of the top mass scheme and decay effects and removes soft contamination. One can obtain $m_t$ in a short distance scheme by fitting our hadron level jet mass distributions to data or by Monte-Carlo calibration. Lepton+jets and all-jet samples can be used. The peaked distributions for $pp$ and $e^+e^-$ collisions are very similar, up to sensitivity to underlying event which is reduced by soft drop.

The use of a graphite tube introduced into an air-acetylene flame for the determination of Pb in solid samples is described. A slurry of NIST SRM 2704 Buffalo River Sediment was prepared and immediately filtered to collect the solid material on a cellulose filter. Small pieces, ≈3.2 mm diameter, of the filter-paper containing the solid material were placed, by means of a thin stainless-steel spatula, inside a graphite tube. This was then introduced into the flame for atomisation and atomic absorption determination of the Pb content of the SRM. Small pieces of the NIST SRM 3087a Metals on Filter Media were also analysed for Pb in a similar fashion. The Pb concentration values determined for the Buffalo River Sediment SRM were 160±20 μg g
 –1
 (certified value 161±17 μg g
 –1
), whereas those for the Metals on Filter Media SRM were 41.54±3.55 μg per filter (certified value 40.38±0.92 μg per filter), confirming the accuracy of the results obtained. The standard deviations for the above measurements performed on the solid samples were, as expected, highly dependent on the homogeneity of the distribution of the analyte in the SRMs and on the uniformity of the layer of solid sample deposited on the filter-papers.


In a CRT high inlet culverts and low outlet valves in the dike allow a limited amount of water to enter and leave the low elevated polder area. The created tidal regime in the CRT has almost the same characteristics as the tidal regime on higher-elevated natural marshes in the estuary. In contrast, the SCS consists of a low single passage through the dike so that the full estuarine tidal range (on average 5.35 m) enters and leaves the low lying area without change of the tidal curve. It may be expected that in CRT-marshes or SCS-marshes the interaction between elevation change and consequent changes in tidal characteristics and soil properties deviate from each other and from natural tidal marshes. In this study we compare results on these variables between the systems and discuss possible underlying causes of the observed differences.


Abstract How can a developing country capture the advantages of globalization? In grappling with this question, China has played to its strengths and picked itself up by the bootstraps, though not without mounting signs of apprehension. This case offers clues to what vaults development forward in globalization. Largely overlooked in this search for a key is the range of China's internal debates. This creative dialogue could help overcome the despair of antidevelopment, a multipronged attack on the whole developmentalist paradigm. Although China's encounter with globalization is problematic and does not offer a model to be copied, it is a compelling case of a home-grown strategy of transformation, hope and self-confidence, and a large measure of self-determination. In other contexts, the Chinese narrative prompts the question of how to write a fresh script for development within the compass of neoliberal globalization.

'Addiction' denotes repetitive routines that aim to obtain chemicals and, less often, routines without that aim. The latter are behavioural addictions. They include obsessive-compulsive disorder (OCD), compulsive spending (including gambling), overeating (bulimia), hypersexuality (straight or deviant), and kleptomania. Common across dependence syndromes is: a repeated urge to engage in behaviour known to be counterproductive; mounting tension until it is completed; rapid temporary switching off of the tension by completing the behaviour; gradual return of the urge; syndrome-specific external and perhaps internal cues for the urge; secondary conditioning of the urge to external and internal cues; similar strategies for relapse prevention by cue exposure and stimulus control. The urge to complete a behaviour and discomfort if prevented from this resemble the craving and the withdrawal (WD) symptoms of substance abusers. Some WD symptoms are common to several addictive syndromes while others may be more specific. Addiction (pull) and compulsion (push) overlap and can occur sequentially or concurrently. Different addictions occur with varying amounts of pleasure at various stages. Prolonged exposure can enduringly reduce the urge and discomfort in OCD, and may help some other addictions. Conditioned cues are important and for lasting efficacy a therapist may need to know their details for each syndrome. There may be some similarities in the early management and prevention of relapse of behavioural and chemical addictions.


Lactate dehydrogenase A (LDHA) encodes an enzyme that catalyzes the inter-conversion between pyruvate and lactate in glycolysis. Here, we demonstrate that LDHA mediates a novel role in DNA repair independent of this metabolic function.

 siRNA screen, The Cancer Genome Atlas (TCGA) survival analysis, ionizing radiation (IR), g-H2AX, and chromatin assays, site-directed mutagenesis.

 In an orthogonal siRNA-informatic screen to identify genes 1) when silenced caused IR sensitivity in patient-derived glioblastoma lines and 2) lowered expression is associated with improved survival in TCGA, LDHA surfaced as the top candidate. The survival association was validated by LDHA immunohistochemical staining in an independent collection of glioblastoma samples. In vitro and in vivo, silencing of LDHA sensitized glioblastoma lines to IR and enhanced radiation-induced g-H2AX accumulation. Such sensitization was not observed after treatment with an LDHA inhibitor, suggesting the metabolic function of LDHA is distinct from its role in DNA repair. Supporting this hypothesis, truncation mutations that suppressed the LDHA glycolysis function minimally affected its role in DNA repair. Mechanistically, cytoplasmic LDHA translocates into the nucleus in response to IR. This translocation was associated with subsequent chromatin transition into an open conformation and enhanced homologous recombination.

 The novel LDHA function in DNA repair suggests intricate crosstalks between glycolytic metabolism and DNA repair, offering a new platform for glioblastoma therapeutic development.


The purpose of this work is to perform high resolution spectroscopic measurements in the terahertz region aiming at molecular parameters, derived from quantum mechanical analysis of the spectra. These parameters are the basic requirement for accurate frequency predictions and for the astronomical detections of undiscovered species. Two di erent spectrometers have been used for the spectral analysis in this work: ˆ The newly designed Supersonic Jet Spectrometer for Terahertz Applications (SuJeSTA) for the investigation of cold radicals and ions ˆ The Cologne Terahertz Spectrometer The pure rotational spectra of ve isotopomers of potassium chloride, i.e. 39K35Cl, 39K37Cl, 41K35Cl, 41K37Cl, and 40K35Cl have been recorded with the well established Cologne Terahertz Spectrometer (see e.g. [1], [2]). A special evaporation cell has been used to evaporate solid KCl. Within the scope of this thesis, a total of 295 new rotational lines have been measured in the frequency region between 170 and 930 GHz. For the isotopomers 39K35Cl and 39K37Cl 107 and 82, respectively, rotational transitions have been assigned to transitions belonging to vibrational levels up to the seventh excited state (v≤ 7) and to rotational quantum numbers as high as 127 and 129, respectively. 104 lines were measured for the less abundant isotopomers of 41K35Cl and 41K37Cl with J ≤ 128, v ≤ 6 and J ≤ 131, v ≤ 5, respectively. Two lines have been assigned to 40K35Cl, which has a natural abundance of 0.01% relative to 39K35Cl. The measured lines have been tted together with previously published millimeter wave transitions to obtain an improved set of molecular parameters for these isotopomers [3]. Besides this analysis, the isotopically invariant Dunham parameters Ui j and the Born-Oppenheimer corrections ∆01 have been determined. The re ned and extended parameter set allows precise predictions in the terahertz region. Structural parameters, such as the bond length and the moment of inertia, have been derived from the spectroscopic parameters. A main task of this work was the construction and assembly of the new Cologne Supersonic Jet Spectrometer for Terahertz Applications (SuJeSTA).

The three‐dimensional Stokes flow in a periodic domain is examined in this study. The problem corresponds closely to the flow inside internal mixers, where the flow is driven by the movement of a rotating screw; the outer barrel remaining at rest. A hybrid spectral/finite‐difference approach is proposed for the general expansion of the flow field and the solution of the expansion coefficients. The method is used to determine the flow field between the screw and barrel. The regions of elongation and shear are closely examined. These are the two mechanisms responsible for mixing. Besides its practical importance, the study also allows the assessment of the validity of the various assumptions usually adopted in mixing and lubrication problems.

Deterioration of concrete structures in the Arabian Gulf region is the major problem facing the construction industry in this region. Assessment of concrete structures is important necessity to evaluate the safety of these existing structures. To determine various physical and chemical characteristics of the concrete, core specimens must be retrieved from the structure. Determining the concrete quality along with compressive strength of structure using cores is considered the best technique at present. A review of the literature indicates that as the sample size increases, greater costs are incurred, and, more significantly, the risk of unduly weakening the structure increases. Though large specimens will ensure a reasonable ratio of specimen size to maximum aggregate size, it is impracticable to obtain such cores. Consequently, small cores may have to be adopted.


Thispaper deals withtheexperimental construction, stochastic modeling andstatistical signal processing ofanovel biosensor comprisingofbiological ionchannels. Suchnano-scale biosensors arebuilt byincorporating dimeric Gramicidin ionchannels into thebilayer membranes ofgiant unilamellar liposomes andthenexcising small patches ofthemembrane loaded withionchannels. We showthat target molecules affect thestatistics ofthegating mechanism ofthe dimeric Gramicidin ionchannels andpresent statistical verifications ontheadequacy ofaHiddenMarkovModelformodeling ofthe biosensor.

Totest thesensitivity ofthis modelwe conducted patch-clamp experiments withandwithout theMethylbenzthonium Chloride compound. Thereal-time detection algorithm wasable toaccurately detect thepresence ofthecompound fromalterations inthepatch-clamp recordings. Thisalgorithm provides the sensitive detection system forongoing development oflipid-based nano-sensors.


We investigate the ground-state phase diagram of the one-dimensional attractive Fermi-Hubbard model with spin-dependent hoppings and an on-site Rabi coupling using the density matrix renormalization group method. In particular, we show that even in the limit of one component being immobile the pair superfluidity can be resonantly enhanced when the Rabi coupling is on the order of the interaction strength just before the system starts to strongly polarize. We derive an effective spin-1/2 XXZ model in order to understand the ground-state properties in the strong attraction limit.


Abstract ISO 31000 – Risk Management Principles and Guidelines was issued in 2009 and has been widely adopted around the world by most of G20 countries, including the US and all BRICS countries. This article presents a balanced view on how the discipline of risk management is developing. It scrutinized the ISO 31000 guidance standard looking at both, positive features and aspects to watch out for. The document represents a shift from compliance-driven risk management to practical performance-driven risk management undertaken by decision makers across all sectors worldwide. A major achievement in today's environment.


In the present study, we report the identification of a new gene from the Bacillus subtilis B3 strain (aatB3), which comprises 1308 bp encoding a 436 amino acid protein with a monomer molecular weight of 49.1 kDa. Phylogenetic analyses suggested that this enzyme is a member of the Ib subgroup of aspartate aminotransferases (AATs; EC 220.127.116.11), although it also has conserved active residues and thermostability characteristic of Ia‐type AATs. The Asp232, Lys270 and Arg403 residues of AATB3 play a key role in transamination. The enzyme showed maximal activity at pH 8.0 and 45 °C, had relatively high activity over an alkaline pH range (pH 7.0–9.0) and was stable up to 50 °C. AATB3 catalyzed the transamination of five amino acids, with l‐aspartate being the optimal substrate. The Km values were determined to be 6.7 mm for l‐aspartate, 0.3 mm for α‐ketoglutarate, 8.0 mm for l‐glutamate and 0.6 mm for oxaloacetate. A 32‐residue N‐terminal amino acid sequence of this enzyme has 53% identity with that of Bacillus circulans AAT, although it is absent in all other AATs from different organisms. Further studies on AATB3 may confirm that it is potentially beneficial in basic research as well as various industrial applications.
