Stable transmission of a sub-μm-sized Ar8+ beam of 64–104-keV energy through glass tandem optics was achieved. The optics consisted of a 4-electrode tapered capillary and a sub-μm-sized tapered capillary tip, arranged in series. To actively discharge the capillary, and thus obtain stable transmission, an electrode was applied with a mechanical relay closing at a 0.01–0.1 Hz frequency. Transmitted beams were observed for tip outlets' diameters of 0.75 and 2.0 μm. When only a 4-electrode capillary was used, a beam density enhancement with a multiplicity of 14 times of the input beam density was achieved. A transmission efficiency up to 70% was observed with good reproducibility when the electrodes were biased with appropriate voltages.


Petroleum exploration activity in Western Australia over the past decade has been on the increase, boosted by the positive results of many new discoveries, mainly on the North West Shelf but also in frontier areas. Significant discoveries in 1999–2000 resulted from new exploration concepts including deep plays in the Barrow/Dampier Sub-basins, heavy oil plays in the Carnarvon Basin, a deep-water gas play west of Gorgon, large gas/condensate plays in the Browse Basin, and a new gas play in the southern Bonaparte Basin. Discovery itself is a great incentive to the industry to further exploration; however, concerns over oil price, the Australian dollar, markets, policies and perceived prospectivity impact on exploration spending. The short-term outlook for WA is good as a result of existing work commitments including an average of 50 exploration wells to be drilled each year for the next three years. Onshore, where exploration has been subdued, there are signs of increased activity. The Western Australian government is playing a key role in promoting the State through gazettals, promotional activities— conferences and publications, acquiring precompetitive data and making petroleum data more accessible. The government funded Petroleum Exploration Initiatives program is continuing and efforts are being made to facilitate exploration. Sustained high oil prices, improvements in technology and efforts to expedite access to land are just some of the factors which will assist companies in their endeavours. In the longer term, continued growth in Western Australia's petroleum industry is projected.


In Q2 2018, the Russian industrial sector managed to recover to a normal state of operation from the failed start early this year. The percentage of enterprises assessing their state as "normal standing" neared an all-time high by mid-2018 (77% compared to 78% in H2 2017).


Enlightenment affirms uniqueness of national literature and fights against external aggression.It also emphasizes diversity of national literature,and advocates equal dialogue between national literatures.It advocates the mutual permeations between national literature and world literature.The Enlightenment has brought us hints: be against cultural hegemony and stresses the jointly development of both national literature and world literature.


Abstract Remarkable consequences of maritime accident can be various, including structural damage, loss of life and marine pollution. During an accidental phenomenon, such as ship grounding, the amount of oil spillage indicates casualties' extent of surrounding sea water. Effort to provide protection for sea environment against such event has been conducted actively by developing navigational instruments, and passively using structural development and assessment. The accidental grounding is, however, a very complicated process with high sensitivity to given factors during its occurrence. Variety in ship type, location, obstruction etc. affected by advance improvement in naval technology, invites sustainable analysis for structural crashworthiness and failure to produce evaluation data. This work aims to perform an assessment on double hull tanker subjected accidental grounding with oceanic seabed as the obstruction. Fundamental concept of bottom raking is used to design grounding scenario using numerical experiment. Non-Linear Finite Element Method (NLFEM) is deployed to idealise tanker structure and obstruction geometry. The selected crashworthiness criteria in grounding are summarised to provide structural prediction in moment double hull members are experiencing crushing process. Influence of geometrical parameters' variation to progressive failure is presented with contribution of double bottom members to structural behaviour in final part. Result data of the current work can be a reasonable reference to understanding double bottom performance in grounding, especially in raking case. Insight of such accidental phenomenon is very useful in further effort to minimise grounding consequences.


Advanced maternal age pregnancies are still prevalent due to ignorance and lack of effective contraception. These pregnancies have a poorer maternal and perinatal outcome.


OBJECTIVE
To explore whether palmitate-induced apoptosis of osteoblastic MC3T3-E1 cell is mediated by an activation of nuclear factor-kappa B (NF-κB).

METHODS
Cell viability was assessed with methyl thiazolyl tetrazolium (MTT) assay and cell apoptosis by Hochest 33258 staining. Palmitate was added at different timepoints and dosages.Western blot was used to evaluate the expression levels of IκBα, p-NF-κB p65 and NF-κB p65 protein.

RESULTS
Palmitate led to a dose- and time-dependent decreases in cell viability and increase in cell apoptosis. Cell viability dropped to 54% and cleaved caspase-3 increased 3.1-fold in cells treated with 500 µmol/L palmitate compared to control. The level of p-NF-κB p65 protein markedly increased at 60 min post-stimulation and reached a 2.96-fold increase of baseline level at 120 min (P < 0.05) . The IκBα level markedly declined at 60 min post-stimulation and decreased by 57% at 120 min (P < 0.05) . Compared to the group with palmitate treatment alone, pyrrolidine dithiocarbamic acid (10/20 µmol/L) significantly inhibited the palmitate-induced increase of p-NF-κB p65 (1.39 ± 0.12, 1.25 ± 0.10 vs 1.76 ± 0.14, both P < 0.05) , restored the palmitate-induced decrease of caspase-3 (2.24 ± 0.28 vs 1.29 ± 0.27, P < 0.05) and inhibited the palmitate-induced increase of cleaved caspase-3 (0.63 ± 0.01 vs 1.13 ± 0.10, P < 0.05) .

CONCLUSION
Palmitate induces apoptosis of MC3T3-E1 cell by an activation of NF-κB.


ses of iconographical problems). The number of typographical errors makes reading an adventure (were Dante's ashes rebutted or reburied? Is it important to love beautifully or live beautifully? Surely Bronzino was Pontormo's pupil and not the other way around?). The inserted Errata slip adds new mistakes to the old. The UMI Research Press appears committed to the hasty publication of quickly revised, selected dissertations. Authors, copyeditors, and general editors must all share responsibility for the quality of production, but it is a pity to see the manuscript of a first (or any) book so badly served-.

Over the last decade, significant research effort has been put into improving the performance of hash join operation on GPUs. Over the same period, there have been significant changes to the GPU architecture. Hence in this paper, we first revisit the major GPU hash join implementations in the last decade and detail how they take advantage of different GPU architecture features. We then perform a comprehensive performance evaluation of these implementations using different generations of GPUs released over the last decade, which helps to shed light on the impact of different architecture features and to identify the factors guiding the choice of these features. We then study how data characteristics like skew and match rate impact the performance of GPU hash join implementations and propose techniques to improve the performance of existing implementations under such conditions. Finally, we perform an in-depth comparison of the performance and cost-efficiency of GPU hash join implementations against state-of-the-art CPU implementation.


Graph theory offers a false and misleading model for an electric network, a tearable orthogonal structure possessing branches only, and no nodes or planes. The unnecessary introduction of nodes and an avalanche of meaningless matrices is a smoke screen to hide the use of tensors, whose appearance is imperative and inescapable. During their analysis, graph theorists must always necessarily return by some legerdemain to the correct tensorial branch theory, which however is camouflaged with a misfit graph terminology.

In this paper we derive permanent‐transitory decompositions of non‐stationary multiple times series generated by (r)nite order Gaussian VAR(p) models with both cointegration and serial correlation common features. We extend existing analyses to the two classes of reduced rank structures discussed in Hecq, Palm and Urbain (1998). Using the corresponding state space representation of cointegrated VAR models in vector error correction form we show how decomposition can be obtained even in the case where the number of common feature and cointegration vectors are not equal to the number of variables. As empirical analysis of US business fluctuations shows the practical relevance of the approach we propose.

Received: 6 April 2018 Accepted: 10 June 2018 Petroleum is the world's primary source of energy and to fulfill the ever-growing energy demands, petroleum is transported throughout the world by various means. Transportation of petroleum through pipelines is one of the principal means of deliverance, because of its significant economic advantages. However, there persists the risk of possible oil spill and gas leakage through these pipelines which could adversely affect the life of the people, environment and can also cause economic loss. Since oil and gas pipelines exists in large networks spread across on regional scale, it is imperative to utilize Geographic Information System (GIS), a rapidly growing technology in oil and gas industry, for predicting the vulnerability of different areas to possible oil spill/gas leakage, by spatial analysis. Fulfilling most of its energy requirements from petroleum, Pakistan has a wide network of oil and gas pipelines spread across the whole country that possess the susceptibility to the concerned hazards. The present study infers to contribute towards the safety of oil and gas industry in Pakistan from future hazards.


Highly scaled (22 nm-node) capacitorless single-transistor dynamic random access memory (DRAM) cell design is investigated via technology computer-aided design (TCAD) simulations. It is found that the gate-sidewall spacer width and operating voltages can be adjusted to reduce band-to-band tunneling (BTBT) and thereby increase data retention time for bipolar junction transistor (BJT)-based operation. Read current variations due to random dopant fluctuations (RDF) are investigated via three-dimensional Kinetic Monte Carlo (KMC) simulations. It is found that BJT-based operation is more robust to RDF effects than metal–oxide–semiconductor field-effect transistor (MOSFET)-based operation.


Introduction:The prevalence of secondary polycythemia is on the rise due to increasing prevalence of obesity, sleep apnea and other chronic cardiopulmonary diseases. While polycythemia vera is well known to increase the risk of VTE, the impact of secondary polycythemia on the development of VTE is less clear. Methods: We utilized the Nationwide Inpatient Sample (NIS) database to identify all adults ≥18 years with secondary polycythemia (ICD-9-CM code 289.0) diagnosed during 2011. NIS is the largest all-payer inpatient database in the US that captures about 20% of all US hospitalizations. The outcome of interest was acute VTE identified using corresponding ICD codes for DVT or PE. We also identified the presence of the following confounding factors: malignancy, venous catheterization, long bone fracture, infection, trauma, mechanical intubation, congestive heart failure (CHF), pregnancy, length of hospital stay >5 days, stroke and prior history of VTE. Multivariate logistic regression was used to assess the impact of secondary polycythemia on the occurrence of VTE controlling the above confounding factors. Multicollinearity was assessed using variance inflation factor (VIF). All p-values were 2 sided, and the level of significance was chosen at 0.05. Statistical analysis was done using STATA 13.0 (StataCorp, College Station, TX) taking into account the complex sampling design of the database. Results: A total of 3,972 hospitalizations with a primary or secondary diagnosis of secondary polycythemia were identified out of a total of 6,840,854 hospitalizations. Concurrent diagnosis of VTE was seen in 4.8% of patients with secondary polycythemia (n=190) as opposed to 2.3% of patients without secondary polycythemia (n=161,122) (odds ratio, OR 2.07; 95% confidence interval, CI 1.75-2.45; p value 5 days. No evidence of multicollinearity was noted in the final regression model (maximum VIF of 1.13). Conclusion: Within the limitations of the study design, our retrospective study indicates an independent association between secondary polycythemia and VTE in patients admitted in the hospital, however, this does not imply causality. Further, our study does not answer whether the use of therapeutic phlebotomy reduces the risk of VTE in patients with secondary polycythemia. Disclosures No relevant conflicts of interest to declare.

Since modern industrial production is a large scale collective work, it involves the joint labour of a large number of people who assemble together in or over a place. This assembling of a large number of people also gives rise to the formation of a society and in this society, like all other societies, there are relations between workers and workers, workers and supervisors and host of other social relations. But most writers on the subject of industrial relations would, however, tend to agree on one point, that is, not all social relations in industry are industrial relations in the true sense of the term. Such a vast variety of routine personal inter actions such as the conversation between workers and workers, workers and managers, allocation of work by supervisor to workers or a gossip between workers and union representatives during a tea break are so trivial and insignificant that they will hardly be considered as a part of industrial relations.


To monitoring of the crack damage located at the bolt hole of metallic bolted-joint structure in real-time, a fatigue crack monitoring scheme based on rosette eddy current sensor is put forward. The characteristics of sensor are analyzed via semi-analytic model, and feasibility of proposed scheme is verified through monitoring experiment using constructed fatigue crack monitoring system. The result of semi-analytic model shows that the magnitude of transimpedance is more sensitive to changing of conductivity and liftoff than phase of transimpedance, and the sensitivity of magnitude increases with the frequency. The result of fatigue crack monitoring experiment of 2A12-T4 aluminum alloy under constant load indicates that viewing the break point as indication of crack position, the rosette eddy current sensor achieves quantitative-monitoring capability of fatigue crack with precision of 1mm and the sensing-channels near fatigue source are capable of qualitative-monitoring of accumulated fatigue damage.


Hamartoma is detected in the breast during screening of breast asymmetry or discovered pathologically in combination with other breast pathologies. Hamartoma should be considered one of the differential diagnoses of breast asymmetry, especially for young women, where mammogram is not frequently ordered or if the patient complains of significant breast asymmetry with no clearly evident breast mass by physical examination and normal breast ultrasound. Hamartoma is detected by mammogram as "'breast within a breast." Ultrasound can diagnose small localized hamartoma and fine-needle aspiration or core needle biopsy of no significant help in diagnosis of isolated hamartoma not assonating with other pathologies. Mammogram and breast magnetic resonance imaging (MRI) are of great help in diagnosing hamartoma especially if it is large occupying the whole breast. Awareness of isolated hamartoma as a cause of breast asymmetry with the help of mammogram or MRI of the breast will lead to early diagnosis and treatment and avoid patient suffering of undiagnosed breast hamartoma.


Abstract Recent plasma-material-interaction (PMI) studies of relevance to fusion PMI science are discussed. The results are a mix of science experiments and in situ diagnostic technology development. Scientific issues addressed include the nature of He and W atom migration in the evolution of W fuzz surfaces, understanding the nature of D retention in damaged W surfaces via modeling with the tritium migration and analysis program, and an examination of synergistic effects associated with D trapping on composite Be codeposit and W substrate surfaces. In situ diagnostic developments discussed include laser-induced desorption spectroscopy for the measurement of bulk hydrogen retention and laser-induced breakdown spectroscopy for the measurement of near-surface composition.


For stereo depth estimation using events and intensity images, we propose an end-to-end deep recurrent residual design taking advantage of a sequence of event representations and intensity images that land before the location of ground-truth depth. From the sequential event and image inputs, we create a feature tensor used for aggregating and estimating regressed depth values. Our method outperforms the baseline method in all sequences and on average for all of the utilized metrics in the competition.


The triethanolamine salt of 2,4,5-TP (Color-Set 1004) was applied at the rate of 900 gallons per acre with a concentration of 20 parts per million to McIntosh and Delicious apples in six different orchards. Spray was applied 10 to 15 days ahead of picking with McIntosh, and 28 to 37 days from picking with the Delicious variety. In orchards where dropping occurred, the spray proved highly effective, even under severe windstorm conditions. Respiration determinations, pressure tests and organoleptic evaluations indicated no increase in maturity or ripening in sprayed as compared with check fruit

Non-steroidal anti-inflammatory drugs (NSAIDs) are one of the most widely prescribed groups of medicines in clinical practice. They are particularly useful in the treatment of rheumatoid arthritis (RA) and osteoarthritis (OA), because of their anti- inflammatory, analgesic and ant-pyretic properties. The recently available cyclo-oxygenase 2 (COX-2) selective inhibitors for arthritic treatment imparts an essential means of reducing gastrointestinal (GI) adverse effects (2), but this new class of drug is not recommended for routine use in patients with RA or OA. The aim of this study was to audit prescribing of COX-2 inhibitors at St Luke's Surgery, Guilford, with the purpose of describing and measuring the nature and extent to which non-adherence to the NICE guidelines occurs.


The EFL and linguistic materials available in Taiwan exhibit a large number of transcription systems, all differing from each other in certain respects. While some of these differences are of linguistic nature, and stem from the authors' own perception of the English phonetic/phonological system, others are purely graphic, frequently having arisen through misinterpretation of the traditional transcription symbols as established by the International Phonetics Association (IPA). The multitude of transcription systems and the differences in graphics for the same phonetic symbols can be said to present a confusing picture of English sounds and their transcription to the students of English in Taiwan. In the present article, the background of the issues discussed above is investigated, and, wherever appropriate, ways to correct some of these non-standard practices are presented. The author also provides some suggestions regarding the reduction of the current multitude of transcription styles by means of standardization.

Barley is one of the oldest domesticated crops by human being and used as staple food for quite a long time (Haas et al., 2018). Over the period of time wheat and rice replaced barley from regular diets and this led to significant decrease in its area and production. However, in last two decades barley has made its place among the nutraceutical grains especially because of relatively higher content of soluble dietary fibres as compared to other cereal grains except oats (Derakhshani et al., 2020). Barley contains significantly higher levels of a soluble fibre called mixed linkage β-1-3;1-4 glucans (popularly known as beta glucans) vis-à-vis wheat and rice. Beta glucans have been shown to reduce low density lipoprotein cholesterol (LDL Cholesterol) and thus providing protective role against cardiovascular diseases (Ames et al., 2008). Regular consumption of beta glucan is also reported to reduce the blood sugar and thus helpful in prevention and management of type-II diabetes (Ames et al., 2008). Consumption of soluble fibre rich diet has been shown to protect against certain kinds of colon cancer (Madhujith et al., 2005). The health benefits of barley were probably known to ancient civilizations and some studies suggest the use of barley in management of type-II diabetes in Indo-Vedic Civilization (Sarkar et al., 2015 there in). Barley has very low glycemic index among the cereal grains. The lower glycemic index foods are considered healthy option especially in case Identification of promising sources of hulless barley (Hordeum vulgare L.) for important quality traits


Internal combustion engines in now a days is the best available reliable source of power for all domestic, large scale industrial and transportation applications. The major issue arises at the efficiency of these engines. Every attempt made to improve these engines tends to attain the maximum efficiency. Here a single cylinder four stroke petrol engine is used for study. In this present work a study about influence of the air swirl upon the performance and emission of a single cylinder four stroke petrol engine is presented. In order to achieve the swirl, diverter tube is used between carburetor and engine to intensify the swirl for better mixing of fuel and air and their effects on the performance and emission are recorded. In particular the performance parameters of engine speed, torque, brake power, volumetric efficiency, brake specific fuel consumption, brake thermal efficiency are examined. In additional the noise and emission parameters percentage of CO and HC has been measured.

High population density is the main factor in environmental problems, where the high speed of human growth caused the vegetation area became deminishing. The aims of this research was to functionized the ALOS/AVNIR-2 image satellites and GIS to calculate the percentage of vegetation in Denpasar city with three index vegetation formulas: NDVI, SAVI dan MSAVI in order to get one formula to build the distribution map based on the percentage of vegetation. This map was used to evaluate the urban planning map 2003 in Denpasar city. Result showed that there was relationships between vegetation index of ALOS/AVNIR-2 images and percentage of vegetations, where the vegetation index of NDVI and SAVI had the highest coefficient determination. The formula of "Percentage Vegetation = 132.71 (NDVI)2 + 3.461 (NDVI) + 5.6775" was used to generate the percentage distribution vegetation map. Based on that map, the dominant vegetation distribution found in settlement area (with percentage vegetation area) lower than 25%. The urban planning for green open area "KDB" 0% was dominated by the area which had a percentage of vegetation between 25-50% and 50-75%. In the other hand, the urban planning for "Tahura", was dominated by the area which had a percentage of vegetation of more than 75%.


In his attempt to challenge colonial hegemony and promote the colonized sense of identity, the Sudanese poet, Mohamed Al-Fayturi is engaged in an intercultural dialogue with his master, the African American poet, Langston Hughes, in order to reconstruct a history devastated by slavery and imperialism. Rooted in a revolutionary basis, the mutual dialogue between the two poets aims to dismantle colonial narratives about Africa and the black people by revising history and rewriting the story of slavery and colonization from the viewpoint of the colonized and the oppressed. Carrying the scars of enslavement and hegemony, Langston Hughes and Mohamed Al- Fayturi poetically engage the history of racism and colonization linking the African literary tradition with its counterpart in the United States.


A vector network analyzer (VNA) with a bulk current injection (BCI) probe is proposed to measure the transmission coe-cient of a PCB. The purpose of developing such a measurement techniques is to predict the radiated emission for good correlation with the fully-anechoic chamber measured results. In this study, the proposed method is used to determine the radiated emission from a DC supply loop. Moreover, the proposed method can be further used to accurately predict the reduction of radiated emission from the improved DC supply loop. Electromagnetic simulations is also developed to conflrm the accuracy of the proposed techniques.


The work investigated compound entities, namely spatially bound LB complexes with angular momentum, called Vortex LBs (VLBs). An experimental excitation scheme using a discrete phase plate, generating a pump beam with the desired angular momentum, is discussed, while retaining the threefold symmetric field pattern with high field overlap with the desired modal field of the discrete VLB.


We consider large-scale optimization problems whose objective function is expressed as the sum of convex functions. Such problems appear in various fields, such as statistics and machine learning. One of the solution methods for the problems is the online gradient method, which exploits gradients of a few functions in the objective function at each iteration. In this paper, we focus on sparsity of two vectors: a solution and a gradient of each function in the objective function. To get a sparse solution, we usually add the L1 regularization term to the objective function. Then, since the L1 regularization term consists of all decision variables, the usual online gradient methods update all variables even if each gradient is sparse. To reduce the computations of all variables at each iteration, we may use a lazy evaluation, which only updates the variables corresponding to the nonzero components of the gradient by ignoring the L1 regularization terms, and evaluates the ignored ones later. Since the lazy evaluation does not exploit the information of the terms at all iterations, the online algorithm with the lazy evaluation might converge slowly. In this paper, we propose a forward-backward splitting type method that exploits the L1 terms corresponding to the nonzero components of the gradient at each iteration.We show that its regret bound is O( √ T ), where T is the number of functions in the objective function. Moreover, we report numerical experiments for the proposed method, which show the proposed method is promising.


The association of acceptor cations (Fe′Ti and Mn″Ti) with oxygen vacancies in Fe- and Mn-doped SrTiO3 single crystals is investigated using in-situ EPR spectroscopy. Effective association enthalpies ΔassH0eff and entropies ΔassS0eff are determined, and ΔassH0eff is found to depend strongly on the dopant concentration. This dependence can be roughly described by a correction term in the chemical potential that is proportional to the cube root of the defect concentration. Extrapolation to infinite dilution yields an association enthalpy of −26 kJ mol−1. The association of oxygen vacancies can significantly reduce the ionic conductivity of these materials at temperatures up to ca. 200 °C (Fe′Ti) or even higher (Mn″Ti), and must therefore be taken into account in the respective defect chemical models at moderate or low temperatures.

A modular and integrated optimisation model for the design of underwater vehicles is presented. In the proposed optimisation model two modules (i.e. low fidelity and high fidelity) are incorporated and the basic geometric definition of computer aided design (CAD) is integrated with computational fluid dynamic (CFD) analysis. The hydrodynamic drag is considered as single objective with constraints on the geometric parameters of dimension, space and volume. The CAD model is implemented in MATLAB*TM and CFD model is implemented in Shipflow**TM. A real-world design example of an existing underwater vehicles is presented. The applicability of proposed optimisation model is shown. The presented results show that within given set or sets of constraints the application of optimisation model in design results into an efficient hull form.


Abstract Indigenous New Zealand members of tribe Triticeae are revised. Three genera are accepted: Elymus in preference to Roegneria; Stenostachys in preference to sectional rank in Elymus; Australopyrum in preference to Agropyron or Hystrix. Two new species of Elymus are described; E. solandri is a new combination for widespread indigenous plants. A new species in Stenostachys is described. Australopyrum is as treated recently. Natural hybrids are described, both interspecific and intergeneric. Genome analyses are discussed especially for hexaploid species.


One book, one article, and a series of archaeological finds have contributed the largest part to the progress of Cyrillo-Methodian studies in the past thirty years. The book was by Father Dvornik: Once and forever its author established the reliability of the Vitae of the Slavic Apostles—our two principal sources for their mission—by carefully fitting them into the framework of Byzantium's history in the ninth century. The article was by Fathers Meyvaert and Devos: In a few pages it demonstrated more mathematico what many foremost scholars had already suspected—that the Vita of Constantine–Cyril was in existence by 882 (before Methodius' death), and that, by this time, it existed in Slavic. The latter demonstration was a hard pill for Byzantinists to swallow. The archaeological finds were made in Southern Moravia. By unearthing several ninth-century towns, archaeologists were able to provide an explanation for the strength of the Great Moravian state; by discovering a number of early churches, they were able to demonstrate how well established Christianity was in Great Moravia even before the Cyrillo-Methodian mission had arrived.


The article reveals the essence of creativity as a mechanism of business management and the reasons for the importance of using such creative mechanisms in the enterprise. It is stated that creativity accompanies innovation, increases productivity, allows to adapt to the external environment, for example, the COVID-19 pandemic, as well as it is necessary for enterprise growth, skills that staff can obtain; it can be an integral part of the whole organization activities. The paper examines the Scamper technique, which is used as a method of brainstorming in the development and improvement of processes, ideas, products in the enterprise. Scamper technique is a system of questions in different directions, after the answers to which, companies will be able to change the situation. It is established that at the stage of replacement, you can look for a replacement for everything, any problem or task, combining will lead to a combination of existing, unrelated ideas, where the solution already exists, but from another area of experience. The modification phase may be a new look at the most important components of the concept of organizational processes, products, services, or problems, another use is often a great idea to solve more problems than before. The article represents the steps that a company and its management can use to bring a special product to market. Using Scamper's creative thinking method, the company can identify those products that need innovation, identify their functions, properties and with the help of components of the methodology to answer questions, repeat these steps several times, thus gaining more innovative product ideas. As SCAMPER can create new solutions, ideas, products and services, as well as create a new environment for thriving innovative trends in the current business environment, it is an invaluable tool for brainstorming and creativity.
Keywords: Scamper technique, creative mechanisms of business management.


We developed a mathematical model of an unstable system of set of N connected inverted pendula. We described principles of stabilization of such a system at the neighborhood of the unstable upright position. Also, we studied dynamics of this system and obtained the limiting conditions ensuring the stability of this system. Simulation results demonstrate several important features of the system's dynamics.


The article was prepared based on the results of monitorings of pedagogical universities, which were carried out by the method of self-completion by representatives of universities of the developed forms for collecting information. This study is an attempt to find out what is happening in the system of pedagogical universities, how the situation is changing related to the need to ensure the availability of higher education for people with disabilities, what organizational decisions are made by the heads of pedagogical universities to ensure that the education of students with disabilities is of high quality and competitive in the modern world labor market. Based on the data obtained, a range of problems has been identified that should be taken into account by representatives of higher educational institutions in order to provide students with disabilities with equal access to quality education. In this article, the author presents and discusses the experience of pedagogical universities in creating special conditions for teaching students with disabilities. The article shows that the formation and development of inclusive higher education requires the combined work of specialists — participants in the university inclusive community. It is concluded that the orientation of the university towards the development of inclusive processes will help ensure the availability of higher education for different categories of students.


Abstract A team from the University of Dayton, consisting of undergraduate students, a faculty facilitator, and practitioner partners, conducted an innovative oral history project documenting the experiences of ordinary people who lived through the unrest following Michael Brown's death in 2014. The Moral Courage Project sought to investigate the spectrum of stories from Ferguson that failed to fit into the extreme and polarized narratives emerging from mainstream media coverage and were, therefore, overlooked. With the testimonies collected, the team produced a multimedia exhibit featuring portraits and audio materials, as well as a podcast series and a storytelling website. This paper describes the origins and outlines of this unique program in the context of an experiential learning framework. While accounting for the project's successes, the author also reflects on ways that student outcomes could have been improved had greater focus been placed on experiential learning processes and structures.


Abstract : The Advanced Electronic Display Systems (ADEDS) task of the SST Technology Follow-On Program includes the installation and flight test of display and navigation/guidance hardware and software developed under this task. This report provides a summary photographic description of the installation in the flight test airplane- 737-100, NASA 515 and a description of the basic airplane performance and systems configuration. Primary locations for installation include the flight deck (First Officer's position), passenger cabin, forward cargo bay, and the weather radar radome cavity. A palletized installation concept was used for installing the experimental equipment except where the function to be performed specified a location not amenable to palletization or where basic airplane equipment racks provided the space required without modification.

This study is concerned with a process known as fumigation in the grain industry. During this process, fumigant is injected at the inlet of storage and is expected to distribute throughout the stored grain to kill the insects in it. The present research focuses on the study of the fumigant (phosphine) flow distribution based on mathematical modelling and numerical simulation through available Computational Fluid Dynamic (CFD) software. In particular, the mathematical modelling is translated into the CFD and simulation is ran to determine areas where insects might find refuge. Hence provide information for conducting more effective fumigation. Numerical simulation using CFD software, for example, FLUENT, is widely known as cost and time effective. However, the numerical simulation needs to be verified before conducting such studies.  For a simple case, the analytical solution exists. Therefore, the analytic solution for a simple case, can be used for verification and serve as a basis for adopting a CFD software, FLUENT for an extended geometry and boundary conditions. The numerical results are found to agree well with the analytical results. Overall, the fumigant gas flows towards the outlet regardless of the position of the outlet.


Objective: to understand the meanings of care in the hospital routine for nursing professionals working in management and care. Methods: qualitative study that adopted the Human Care Theory as a reference. 38 nursing professionals participated, including service coordinators, directors, nurse assistants and nursing technicians. Data collection took place through semi-structured interviews recorded, transcribed and submitted to Content Analysis, Thematic modality. Results: three categories emerged: possible and necessary: the rescue of meaning and subjective values of care; scientific and human potential as a determinant of care; and difficulties involved in care. Conclusion: care in the hospital routine was perceived by nursing managers and care professionals as an event monitored and influenced by operational aspects, of a more objective nature, as institutional barriers for bonding, but mainly due to subjective aspects, linked to the way of being of the heath professional which shape humanistic care. Descriptors: Nursing Care; Nursing, Team; Empathy; Health Management.

The concept of human care is an essential characteristic of nursing, with the aim of promoting the well-being of individuals, families and communities. It is understood, therefore, that, regardless of the position, the nurse's work contemplates several dimensions: care and assistance, teaching and education, research and management/administration, to a greater or lesser extent, which makes it complex(1). Nurses in management positions, like nursing directors, perform activities with the objective of achieving quality care and the success of the institution. To this end, daily actions emphasize the coordination and organization of the institution, service units, staff, and decision making. In turn, the coordinating nurses work in the direct administration of the unit, considering the provision of physical, material and human resources for care management(2). Assistants respond directly for improvements related to care, managerial activity, coordination of the nursing team and enabling the care process(3), being a reference for nursing services, which can influence team members in the way they perform care(4). In this context, the performance of the nurse's functions in the practice of care can have different meanings, depending on who performs it, receives it and the environment in which it occurs. For a group of women with breast cancer, for example, nursing care must be based on the communication process, from which they can expose their physical, emotional and spiritual needs, and they consider it essential that the professional understands, from the patient, the impact caused by falling ill(5). From the perspective of a group of nursing professionals from a pediatric inpatient unit, care was translated as the expression of affection for children, and the art of promoting a safe and affectionate environment for them(6). It is noticed that, although researched in different contexts, for professionals, the meanings of care have similarities in their meanings. Thus, when reflecting on care, it is understood that the attitudes of nursing professionals need to be constantly reassessed. Thus, considering the experiences of caring, the hospital routine and the premise that the identification of characteristics and fundamental elements for care can help in the recognition of what is really important and that makes a difference in the care routine, in addition, the perceptions about care, the different components of the nursing team (directors, in charge of the divisions of hospitalization and care, sector supervisors, nursing assistants and nursing technicians) can effectively contribute to the construction of reflection and conception about holistic/ integral care, a fact often neglected by institutions, due to difficulties in providing moments of interaction between hierarchical instances. Therefore, this study aimed to understand the meanings of care in the hospital routine for nursing professionals working in management and care.


There has been growing interest in the inclusion of almond hulls and citrus pulp in the diet of Australian dairy cows during summer when pasture availability is limited and digestibility is low. However, there is little information on the resulting milk production response. Thirty-two Holstein Friesian cows were offered one of three diets (lucerne hay, lucerne hay plus almond hulls, lucerne hay plus citrus pulp). Cows fed almond hulls had a lower mean milk yield than those on the other diets. Mean fat yields from cows did not differ between diets. Mean protein yields of cows fed almond hulls were lower than those of cows on the other diets. Methane yield (g/kg dry matter intake) from the cows did not differ between diets. Both almond hulls and citrus pulp can be fed to dairy cows as a partial replacement for high-cost purchased forage, but inclusion of almond hulls may be less desirable than citrus pulp due to reduced yields of milk and milk protein. Neither almond hulls nor citrus pulp exhibited any methane mitigation effect in dairy cows.


During 2002, occurrence of white button mushroom diseases was monitored in mushroom farms in Serbia. Etiology of dry and wet bubble disease, occurring in four mushroom farms (two located in Požarevac, one in Vracevsnica and one in Padinska Skela) was investigated. Strains of mycopathogenic fungi were isolated from the diseased mushroom tissue. Based on their pathogenic and morphological characteristics, the isolates were identified either as Verticillium fungicola or Mycogone perniciosa. The appropriate disease control was suggested in accordance with the relevant literature.


Background Down‐regulation or modulation of T cell activity by immunosuppressive drugs is an effective treatment in diseases where exaggerated T cell responses play a role. A primary effect of the anti‐inflammatory drugs (AIDs) is inhibition of the synthesis of growth factors, such as IL‐2, thereby down‐regulating T cell proliferation. However, it is still largely unknown to what extent these AIDs are able to down‐regulate specifically type‐1 or type‐2 T cell cytokine production, and whether they can down‐modulate chemokine receptor expression, thereby preventing migration of T cells to the site of inflammation.


This address was given at a forum in November J999 for practitioners in the juvenile justice, alcohol and drug, mental health and child protection services in Victoria as part of the Department of Human Services' Working Together Strategy' (WTS). The WTS is a quality improvement initiative of the DHS in partnership with adolescent mental health and drug treatment service providers. WTS provides an organisational framework for the Community Care Division, the Aged, Community and Mental Health Division and the Public Health Division (specifically in reference to the mental health, child protection and care, juvenile justice and drug treatment services programs) to achieve better outcomes for shared clients. WTS is a response to perceived deficits in cross-program collaboration and communication in cases involving high need adolescent clients.


STATUS is an extremely powerful and useful database management package. It offers very rapid response time for searches and provides for storage of free text entries.

Poly(phenylsilsesquioxane) (PPSQ) polymers that were obtained from different synthetic routes were comparatively studied. The polymers were characterized by infrared and solid-state 29Si NMR spectroscopies. According to the results of X-ray diffraction and thermogravimetric analyses, the materials richest in silanol showed a less organized network and lower weight loss temperature. The morphology of the products was influenced by the preparation conditions. PPSQ, with a morphology rich in spherical particles, was achieved with an n-hexadecyltrimethylammonium bromide template in the reaction medium, whereas the morphology of this polymer obtained in the absence of the template was featureless. Small-angle X-ray scattering analyses revealed that the PPSQ samples showed a predominance of surface-fractal behavior. © 2000 John Wiley & Sons, Inc. J Polym Sci A: Polym Chem 38: 1580–1589, 2000

Abstract This paper describes the use of 75Se-selenomethionine in the study of thyroid nodules. Making use of the different main gamma energies of 75Se and 125I and the short physical half-life of 99Tcm, sequential comparison scanning was carried out in a series of 48 patients with solitary thyroid nodules in which histology was established. Preliminary phantom studies and measurements on a biopsy specimen established that the threshold of detectability of a tumour was 1·5 cm diameter for 75Se and 0·5 cm for 125I. The absorbed dose for the activities used was estimated to be 4·5 rads to the liver and 1·05 rad to the gonads from 150 μCi of 75Se and 30–105 rads to the thyroid gland from 75 μCi of 125I. Eight out of 11 malignant conditions gave positive 75Se-selenomethonine scans. There were only four positive scans in 32 benign conditions and three of these were attributable to physiological or pathological change. The value of the complementary scans was shown in solitary nodules. Diffuse uptake of 75Se-se...


Project Management is the application of knowledge, tools, techniques and skills to any project activities to meet the requirements of the project. Usually many construction industries in India do not practice the use of project management properly. Poorly managed projects usually result in a huge amount to all stakeholders not just financially but also psychologically and emotionally as well as it also consumes a lot of time. This has greatly motivated us to carry out the working and functioning of a project using modern project management tool, one of which is MSP (Microsoft Project). This paper consists of planning and scheduling of various activities involved in a construction project using MSP. The presented work clearly gives the difference between carrying out the work using MSP and traditional planning techniques. The presented work has been carried out on a residential building in Mumbai and it clearly shows how the use of MSP software can speed up the construction making it cost effective. Methodology for the presented work includes defining the problem statement, collection of data and finally coming to the conclusion.


Pattern search is an important class of queries for time series data. Time series patterns often match variable-length segments with a large search space, thereby posing a significant performance challenge. The existing pattern search systems, for example, SQL query engines supporting MATCH_RECOGNIZE, are ineffective in pruning the large search space of variable-length segments. In many cases, the issue is due to the use of a restrictive query language modeled on time series points and a computational model that limits search space pruning. We built T-ReX to address this problem using two main building blocks: first, a MATCH_RECOGNIZE language extension that exposes the notion of segment variable and adds new operators, lending itself to better optimization; second, an executor capable of pruning the search space of matches and minimizing total query time using an optimizer. We conducted experiments using 5 real-world datasets and 11 query templates, including those from existing works. T-ReX outperformed an optimized NFA-based pattern search executor by 6x in median query time and an optimized tree-based executor by 19X.


The overall process of coal combustion takes place in two successive steps: devolatilization and char combustion. The fate of sulfur during the devolatilization of coal of different rank was investigated. The significance of the investigation is in fact that a major part of sulfur release occurs during devolatilization of coal, (i.e., emission of sulfur oxides during combustion of coal largely depends on sulfur release during devolatilization). The experimental investigations were conducted to obtain the data about the quantitative relation between sulfur content in the coal and sulfur content in the char. Standard procedures were used for obtaining the chars in a laboratory oven and determining the sulfur forms in the coal and char samples. The experiments were done with grounded coal samples ( 0.9, were noticed in the case of all coals.


Extant research consistently illustrates the positive benefits customers get from having more innovative suppliers. However, do suppliers benefit financially from positioning themselves as leading innovators? Utilizing a secondary dataset of 1039 supplier to customer base observations, and grounding our study in the structure-conduct-performance framework, we examine the extent to which suppliers are able to benefit from pursuing a more leading or lagging innovation strategy within their industry. While in general we find that suppliers employing a leading innovator strategy have higher levels of financial performance, such an effect is not universal. Rather, the ability of the supplying firm to leverage their innovation strategy into increased performance is highly contingent upon not only the innovation levels of their own industry, but also the innovation levels of the industries which they supply. Our results, therefore, suggest that it would be advantageous for suppliers to take a supply chain perspective and strategically incorporate the innovation characteristics of their customers when determining whether to pursue a leading or lagging innovation strategy.


Firms rarely supply only single product. Multiproduct firms are able to cross-subsidize among product lines which could lead to below-cost pricing on part of products. This paper develops a new model to analyze below-cost pricing by multiproduct firms. We show that below-cost pricing arises in equilibrium in the absence of any efficiency justifications stemming from asymmetric information on prices, and it serves as a discriminatory mechanism for screening consumers with heterogeneous shopping costs. In all equilibria firms earn positive profits from multi-stop shoppers who incur lower shopping costs, in spite that pure price competition dissipates its profit from one-stop shoppers. We show also that banning below-cost pricing could improve social welfare but may lead to higher prices for consumers. JEL Classification: L11, L41

The use of dioxin contaminated
 grassland for feed production or grazing is associated with the risk of
 exceeding the maximum permitted levels in feed or food. Nevertheless, there
 are some substantial arguments (e. g. flood prevention) for an ongoing use of
 these exposed areas. It is achievable to produce feed and food with dioxin
 contents below the maximum levels if the production conditions (roughage
 production, feeding and animal husbandry) are adapted to this special
 situation of exposure.
 The aim of this study was to
 investigate whether a special form of fattening of primiparous
 beef cows (so called "Farsenvornutzung") would
 allow the use of grassland which is exposed to dioxins with regards to
 maximum permitted levels. The hypothesis of this concept was: If the dioxin
 contaminated feedstuffs are substituted by uncontaminated ones before
 slaughter the dioxin body burden of the animal decreases, resulting in "safe" beef (dioxin content < maximum permitted level).
 The dioxin burden in the carcasses should be reduced by fattening with
 uncontaminated feed during the last months before the slaughter
 of the animals. Some reduction in the body burden may occur due to the dioxin
 excretion via milk, too. Therefore, a farm with eminently exposed grassland
 was chosen (Lower Saxonian Elbe Valley) as the
 subject of this field work. This farm provided 51 heifers (3 groups: F I, F
 II, F III) which initially received potentially contaminated feed: grass in
 the summer (grazing on the outer dike) and contaminated grass silage during
 winter housing. For using the partly high contaminated feed an official
 permit was necessary. For a well-founded assessment of the dioxin
 contamination of the habitat, feed and the animals, multiple matrices were
 analyzed by HRGC/HRMS for their dioxin (PCDD/F) as well as dl-PCB contents
 (LAVES, Oldenburg). These matrices included, among others, soil samples (LUFA
 Nord-West, Hameln) of the pasture (outer dike of the river Elbe) as well as
 "contaminated" feed (grass silage and grass from areas on the outer dike). To
 ensure that only uncontaminated feedstuffs were used before the slaughter,
 these feedstuffs were analyzed, too. The primiparous
 beef cow´s colostrum and milk as well as – after slaughter – muscle
 (individual samples) and liver (pooled samples) were collected. The carcasses
 only entered the food chain if the results did not exceed the maximum
 permitted level. Because the livers were discarded anyway, owing to the
 high-risk status of the farm ("Risikobetrieb"),
 individual samples were not necessary (pooled samples due to financial
 reasons). Additionally to the 51 heifers participating in this concept,
 muscle and liver samples of further animals were collected and analyzed: one
 heifer (contaminated feed until slaughter), 6 cows (5.5 months uncontaminated
 feed before slaughter), one weaning calf (3.5 months uncontaminated feed
 before slaughter) and two stillborn calves.
 Essential results
 The soil samples
 contained 44.0 - 153 ng WHO-PCDD/F-TEQ/kg DM (proof of the
 particular exposition of the pasture). The "contaminated" grass
 silages had dioxin contents of 1.71 - 4.82
 ng WHO-PCDD/F-TEQ/kg feed (88 % DM) so that all exceeded the
 maximum level (0.75 ng WHO-PCDD/F-TEQ/kg feed [88 % DM]). Two grass samples
 showed high dioxin contents (0.74 resp. 3.64 ng WHO-PCDD/F-TEQ/kg feed
 [88 % DM]), too. In all remaining grass samples, the dioxin
 contamination varied between 0.11 and 0.46 ng WHO-PCDD/F-TEQ/kg feed
 (88 % DM). The "uncontaminated" feed contained 0.09 –
 0.41 ng WHO-PCDD/F-TEQ/kg feed (88 % DM).
 The muscle sample of
 the primiparous beef cow
 F 0 (contaminated feed until slaughter) had a dioxin content of
 3.65 pg WHO-PCDD/F-TEQ/g fat (> maximum
 level: 2.50 pg WHO-PCDD/F-TEQ/g fat).
 Furthermore, the sum of PCDD/F and dl-PCB exceeded the maximum level, too.
 The heifers belonging to the group F I were
 fed with uncontaminated feed 3 / 3.5 / 4 / 5 / 5.5 resp. 10 months before the
 slaughter. The dioxin content in their muscle samples varied
 between 0.61 and 1.73 pg WHO-PCDD/F-TEQ/g fat (all
 < maximum level). The heifers belonging to the group
 F II were fed with uncontaminated feed for 5 / 7 resp. 9.5 months
 before the slaughter. The muscle samples contained 1.04 - 2.26 pg WHO-PCDD/F-TEQ/g fat (all < maximum level).
 One single sample exceeded the maximum
 permitted level for the sum of PCDD/F + dl-PCB (high dl-PCB
 content). The heifers belonging to the group F III were
 fed with uncontaminated feed for 2.75 / 4.5 / 5 resp. 5.75 months before the
 slaughter. The dioxin burden in their carcasses varied between 1.04 and 3.29 pg WHO-PCDD/F-TEQ/g fat (1 sample > maximum
 level). The pooled liver samples of these primiparous beef cows (group F I – F III) contained
 dioxin contents of 6.22 - 20.11 pg WHO-PCDD/F-TEQ/g
 fat so that all exceeded the maximum level (4.50 pg WHO-PCDD/F-TEQ/g fat).
 Conclusions
 The production of "safe" beef
 (PCDD/F content < maximum level) from animals grazing on dioxin loaded
 grassland and by feeding roughage containing notable amounts of PCDD/F is
 possible, but only if the contaminated feedstuffs were substituted by
 uncontaminated ones for a sufficient period of time before the
 slaughter of the animals. The results of this study show that if the animals
 were fed uncontaminated feed at least 3 months before slaughter and – in this
 time – their body weight increased about 10 % and additionally, some dioxins
 were excreted via milk (no absolute necessity), the dioxin burden in the
 carcasses of these animals decreased below the maximum permitted level for
 beef. In accordance with these results, it may be possible to use dioxin
 exposed grassland for the production of "safe" beef – regarding the consumer
 protection – which is of a high quality. Nevertheless, it should be noted
 that the livers of all these animals have to be excluded from the food chain
 by all means. However, the implementation of this feeding-concept would
 require a change in the current legislation: The restrictions associated with
 the universal feed ban for feeds exceeding the maximum permitted level of
 contamination would necessarily have to be eased in order to allow the use of
 feed exceeding the maximum permitted level for "undesirable substances" for a
 certain time.


In this paper, we consider a $2\times 2$ hyperbolic system originates from the
theory of phase dynamics. This one-phase problem can be obtained by using the
Catteneo-Fourier law which is a variant of the standard Fourier law in one dimensional
space. A new classical existence and uniqueness result is established by some
a priori estimates using the characteristic method. The convergence of the solutions
to the one of classical Stefan problems is also obtained.

The formalism of Analytic Multi-Regge Theory is developed as a basis for the study of abstract Critical and Super-Critical Pomeron high-energy behavior and for related studies of the Regge behavior of spontaneously broken gauge theories and the Pomeron in QCD. Asymptotic domains of analyticity for multiparticle amplitudes are shown to follow from properties of Field Theory and S-Matrix Theory. General asymptotic dispersion relations are then derived for such amplitudes in which the spectral components are described by the graphical formalism of hexographs. Further consequences are distinct Sommerfeld-Watson representations for each hexograph spectral component, together with a complete set of angular momentum plane unitarity equations which control the form of all multi-Regge amplitudes. Because of this constraint of Reggeon Unitarity'' the Critical Pomeron solution of the Reggeon Field Theory gives the only known non-trivial'' unitary high-energy S-Matrix. By exploiting the full structure of multi-Regge amplitudes as the Pomeron becomes Super-Critical, the simultaneous modification of hadrons and the Pomeron can be studies. The result is a completely consistent description of the Super-Critical Pomeron appearing in hadron scattering. Reggeon Unitarity is satisfied in the Super-Critical Phase by the appearance of a massive gluon'' (Reggeised vector particle) coupling pair-wise to the Pomeron.


Gerbera or Transvaal daisy (Gerbera jamesonii) is one of most important cut flowers in the world. One of the most problems faced the flowers is the short-life after harvest and neck bending. Producers want to increase longevity of these flowers with using chemical solutions. In this study, effects of various postharvest treatments on postharvest quality and quantity parameters of Gerbera were evaluated. The present study was carried out in Department of Horticulture, Faculty of Agriculture, Islamic Azad University of Isfahan (Khorasgan) branch. Flowers were kept in preservation solutions containing with different levels of preservatives, including, Nano-Silver ( , , ppm). Completely Randomized Factorial Designs was applied to test the significance of treatments and means were compared using Duncan's multiple range test at P = . Results showed that using postharvest treatments significantly affected vase life, stem and flower diameter, related fresh weight and carotenoids total contents. However, the effects of treatments on leaf longevity, PH and water content percentage of florets were not significant. About of using Nano-Silver the best dosage of each material was ppm. In conclusion, the best treatment to enhance postharvest factors of Gerbera, was the exact ppm Silver Nano particles. This treatment can be proposed as additional substance for Gerbera postharvest quality increasment.


Transgenerational marking enables mass-marking of larval fishes via transmission of enriched stable isotopes from mother to offspring, but potential impacts on the resultant progeny are poorly understood. We injected enriched stable isotopes (137Ba and 87Sr) into female purple-spotted gudgeon, Mogurnda adspersa, to produce multiple batch markers and examined larval morphology at hatch as well as survival and growth to 31 days posthatch in marked and unmarked offspring. Transgenerational marking had minimal effects on larval growth and survival, whereas body depth at hatch was significantly reduced in marked larvae. A meta-analysis of transgenerational marking effects on larval morphology at hatch and growth rates across multiple fish species found a nonsignificant positive effect of enriched stable barium isotopes on larval morphology at hatch, but a significant negative effect on growth. There were no significant effects of strontium on morphology or growth. Meta-regression analysis revealed that larval ...


In this work, we study the figure of the tribunus uoluptatum, a not much known official who performed his office between the Vth and VIth centuries. We examine his date of creation – shortly before year 414 – and the cities where it is mentioned – Rome and Milan. We analyze also the law of the Theodosian Code concerning this office (XV, 7, 13), as well as the letters of the Variae of Cassiodorus, mainly the formula tribuni uoluptatum (VII, 10). We finish this study with the prosopographical notices of the tribuni uoluptatum known by the moment, and with one annex of the texts of Variae where Cassiodorus cite this official.


Calyceal diverticulums are often benign and asymptomatic. On the other hand, some interventions are necessary in several symptoms. Radiological imaging is performed to made dianoses, but somehow can pose misinterpretation of radiological imaging results and mistreatment from the urologist. To present a case of a calyceal diverticulum treated with open diverticulectomy. This study reported a case of a calyceal diverticulum in a 30-year-old man with an almost 1-month history of left flank pain. The patient undergone several imaging diagnostics, before finally diagnosed calyceal diverticulum with a stone inside it. The patient had underwent open diverticulectomy. Initially, cystoscopy and insertion of Double J Stent (DJ Stent) were done, and then using the lumbotomy approach the incision that had been made. This case demonstrated the use of imaging combined with urologist interpretation and surgical management which was successfully treated the patient's clinical problems.

Text similarity measurement is the basis of natural language processing tasks, which play an important role in information retrieval, automatic question answering, machine translation, dialogue systems, and document matching. This paper systematically combs the research status of similarity measurement, analyzes the advantages and disadvantages of current methods, develops a more comprehensive classification description system of text similarity measurement algorithms, and summarizes the future development direction. With the aim of providing reference for related research and application, the text similarity measurement method is described by two aspects: text distance and text representation. The text distance can be divided into length distance, distribution distance, and semantic distance; text representation is divided into string-based, corpus-based, single-semantic text, multi-semantic text, and graph-structure-based representation. Finally, the development of text similarity is also summarized in the discussion section.


A novel design for a deep-well InP-based QC-laser structure has been realized using MOCVD growth for emission wavelengths of 4.6 mum-4.8 mum with low threshold current density (1.5 KA/cm2) at room temperature (RT) and reduced temperature sensitivity.


This paper examines the use of belief legends about witches, werewolves, and fairies at open-air festivals in Croatia today. At such events, traditions based on belief legends are invented with the idea of enriching local tourism not only as a source of income but also as a medium through which they portray their local identity. Additionally, the author argues that the concept of fear plays a significant role in the entire process. Visitors face the fear invoked by supernatural concepts, but within the monitored and controlled festival environment, which this helps them overcome their fears and learn how to control them. Furthermore, the author argues that people are increasingly turning toward learning and knowing about supernatural beings of belief legends because they offer an attractive explanation for the functioning of the current world and afterlife.

In a previous report, it was revealed that the k–ε turbulence model, which assumes an isotropic eddy viscosity, was not appropriate for the prediction of an anisotropic in–cylinder flow field. In this article, the k–ε turbulence model is modified so as to be applicable to the anisotropic in–cylinder flow, using a flux Richardson number which represents the effect of anisotropy of turbulence on turbulent diffusivity. A comparison between the prediction and the experimental data, obtained by an LDV system using a transparent cylinder engine, shows that the modified k–ε turbulence model allows successful prediction of the mean flow field but little improvement regarding the turbulence field.


Sneezes are more common than coughs in healthy individuals and cover a much larger space. Properly modeling sneezing can help understand asymptomatic transmission and aid in the optimal design of crowded indoor spaces.


Objective It is to evaluate the clinical applications of multi-slice CT(MSCT) and digital radiography(DR) and its effect factors in the diagnosis of gastric ulcerated carcinoma.Methods 34 cases patients with gastric ulcerated carcinoma proved by surgical pathology were examined by MSCT and DR in one week before operation.All the images of MSCT(including multi-planar reconstructions, CTVG,SSD,Ray sum) and DR were viewed respectively by two radiologists separately with double-blind method.The results of MSCT and DR were compared with that of postoperative pathology respectively.Results There are 38 ulcerative lesions detected by surgery and pathology,of whom 35 were detected by MSCT and 37 by DR,while 34 were localized correctly by MSCT and 37 were by DR,and 35 were diagnosed correctly by MSCT,and 36 by DR.The correct classifications of Borrmann Ⅱ and Ⅲ in 34 advanced ulcerated carcinoma were 31 on MSCT,and 22 were on DR.Conclusion There were no significant differences in the detection,location,qualitation of gastric ulcerated carcinoma between MSCT and DR,but MSCT is superior to DR in making Borrmann classification.


Objective: To explore the association of chlamydia pneumoniae (CP) infection with acute myocardial infarction (AMI) and the possible mechanism. Methods: The specific immunoglobin G (IgG) and immunoglobin M (IgM) antibody to CP were detected by micro-immunofluorescence assay and the values of blood lipid and blood glucose were determined in 30 patients with AMI and 30 healthy subjects. Results: The chronic CP infection rate in AMI patients was significantly higher than that in healthy controls ( 73.33 % vs. 33.33%, P 0.05). The levels of triglyceride (TG), total cholesterol (TC), and low density lipoprotein cholesterol (LDL-C) in patients with chronic CP infection were significantly lower than those in patients without chronic CP infection ( P 0.05 ). Conclusion: CP chronic infection may be one of the risk factors of atherosclerosis, and it may cause atherosclerosis by inducing dyslipidemia.


There are proposed a method and a device for regulating the position of a control element (1), which prevent damage to the actuating element by collision with at least one stop (25, 30) and ensure good dynamic properties simultaneously. Here, the position of the actuating element (1) is within a motion range to a target value is tracked. The adjustment range is limited by at least one stop (25, 30) for the actuating element (1). It is checked whether the distance between the target value for the position of the actuating element (1) and the at least one stop (25, 30) a first predetermined value (S1) below. Only in this case, a change of the setpoint is limited.


Today the chemical fertilizers used in agricultural applications have been an important factor pollution of environmental. Goksu Delta is an important wetland where the Goksu River reaches to sea in the eastern of the town Tasucu-Mersin. The delta is classified as a Wetland of International Importance according to the Ramsar Convention. In this area, use of excessive fertilizer effects the surface and groundwater quality negative. Because of the Delta's geological structure, soil characteristics and climatic conditions, groundwater quality is affected very easy from the surface activities. In the agricultural activities intensively used fertilizers and pesticides contain not only N and P compounds but also some heavy metals. This study aim is investigation of heavy metal pollution sourced from fertilizers in groundwater with a new approach. For this, the most widely used fertilizer in the area (ammonium nitrate) and a groundwater samples were taken at three different time periods and were analyzed (electrical conductivity (EC), salinity (Sal), temperature(T), pH, iron (Fe), copper (Cu), chromium (Cr), manganese (Mn), nickel (Ni), zinc (Zn), cadmium (Cd), lead (Pb)). The results were transferred to Scholler semi-logarithmic diagram which is a new approach in identifying pollutant sources to show the effect of fertilizer. In addition to, the results were compared with the limit values in order to determinate the quality of groundwater. Especially, samples that were taken in the rainy season (1.Period), with the effect of infiltration were detected high heavy metal concentrations. Analyzing the Scholler semi-logarithmic diagram results, fertilizer (ammonium nitrate) has been determined to be effective to heavy metal pollution in groundwater in different three periods. This diagram never before has been used to determine pollutant sources. This study will be a guide for estimating sources of soil and groundwater pollutant in agricultural areas.


With the rapid development of mobile Internet and increasing numbers of mobile devices, mobile edge computing (MEC) which offers computational capability within radio access network has become the key technology to enhance users' experience. In this paper, we investigate the computing offloading problem considering delay and energy consumption of mobile devices jointly in wireless access network. Then, the optimization problem minimizing the delay and energy consumption of mobile devices is formulated and transformed into convex optimization. To solve the optimization, a delay and energy consumption efficient offloading algorithm (DEOA) based on alternating direction method of multipliers (ADMM) is proposed. The simulation results show that the proposed algorithm significantly reduces delay and energy consumption compared to stochastic allocation. Meanwhile, compared with joint delay and energy efficient offloading scheme (JCDE) proposed in another paper, the consumption is reduced while the average speed of solution is increased by about 65% under various system parameters.


Chronic right ventricular hypertrophy (RVH) has been shown to produce changes in left ventricular diastolic properties but minimal effects on left ventricular systolic function. We studied the effects of chronic pressure overload RVH on left ventricular systolic function before and after reversible hypothermic global ischemia. RVH was induced by pulmonary artery banding (PAB) in newborn piglets (5 to 7 days). At 2 months of age the PAB group (n = 6) and a control group (n = 8) were subjected to cardiac arrest on cardiopulmonary bypass with cold crystalloid cardioplegia (10° C) for 2 hr and were reperfused for 1 hr. Left ventricular function was assessed by a conductance catheter in the left ventricle measuring the end-systolic pressure-volume relationship (Emax). Preischemic and postischemic Emax were the same in the control group (4.1 ± 0.4 mm Hg/ml before vs 4.1 ± 0.4 mm Hg/ml after ischemia), but significantly different in the PAB group (4.7 ± 0.5 mm Hg/ml before vs 2.97 ± 0.7 mm Hg/ml after ischemia, p < .05). There also was a marked drop in ATP and phosphocreatine (CP) content in the PAB group during ischemia (ATP, 20 + 2 mmol/kg dry wt before vs 10 ± 2 mmol/kg dry wt after ischemia, p < .05; PC, 26 ± 3 mmol/kg dry wt before vs 1 1 ± 1 mmol/kg dry wt after ischemia, p < .05). In the control group there was no change in ATP content and, although CP did drop by end-ischemia, there was complete recovery by 1 hr of reperfusion but minimal CP recovery in the PAB group. We conclude that isolated RVH has a profound depressive effect on both postischemic left ventricular systolic function and ATP metabolism after global ischemia. Circulation 76(suppl V), V-168, 1987. IMPAIRED CARDIAC FUNCTION in patients undergoing surgical repair of congenital cardiac lesions associated with right ventricular hypertrophy has been well documented.' We have observed that children with marked right ventricular hypertrophy have limited cardiac reserve immediately after surgical repair as assessed by volume loading Sarnoff curves. t During volume infusion, there was no rise in cardiac output, and in some cases, a deterioration in cardiac function was seen.

The purpose of the present study was to assess the effects of right ventricular hypertrophy on left ventricular systolic function and metabolism before and after cold potassium cardioplegic arrest.


This article, in the sociopsychological and clinical tradition, proposes a reflection on the practice analysis groups ; their objectives, and the contexts in which they take place. Based on the presentation of a method of analysis and the effects of its implementation within training groups, the author finally tries to show the impact of a constraining formalization of the interactions and of the analytical work upon the working situations. Then, from several difficulties met when using the method, the author develops the stakes of the development of the "subjectivation" processes within institutions and the necessity to extend the analysis beyond the group, towards institutional and dimensions of the organizations and professional groupings of the environment.


There's presently a growing demand for cw high current proton and deuteron linear accelerators based on superconducting technology to better support various fields of science. Up to now, high order modes (HOMs) studies induced by ion beams with current higher than 10 mA and even 100 mA accelerated by low beta non-elliptical Superconducting rf (SRF) cavities are very few. Peking University has recently designed and fabricated a beta=0.09 162.5 MHz HWR cavity to study the key physics problems in accelerating beam with current of about 100mA. This paper focuses on the study of the HOM-induced power in this cavity. The incoherent beam energy loss induced by 100 mA beam through the HWR SRF cavity were obtained from both time domain solver and frequency domain eigenmodes spectrum method. We also analysed the possibility of coherent excitation of this cavity considering of manufacture errors.

Background: Daily chest X-rays (CXR)s for the sole purpose of verifying the position of the endotracheal tube (ETT) have been deemed by the American Academy of Pediatrics to be one of the top 5 unnecessary tests that increase cost and utilize resources but do not increase efficacy nor safety. Restricting the frequency of CXRs is not associated with an increase in hospital mortality, increased length of stay, nor an increase in duration of mechanical ventilation. Objective: To evaluate the effectiveness of a restrictive CXR protocol in the Neonatal Intensive Care Unit (NICU) by assessing …


Convection in a low Prandtl number fluid driven by the combined mechanism of buoyancy and surface tension is investigated in the presence of a uniform vertical magnetic field. The fluid is contained in a square cavity with the upper surface open and isothermal vertical walls. The thermal conductivity k of the fluid is assumed to vary linearly with temperature The governing equations are solved using ADI and SOR numerical techniques. The heat transfer is found to decrease appreciably across the cavity with a decrease in k. The accumulation of streamlines by Lorentz force is seen for linearly varying k.


The quantity of industrially polluted waters is increasing everywhere, of which a significant part is occupied by a number of mono- and poly-aromatic compounds. Toxins enter the soil, sewage, and clean water by mixing with or seeping into them from industrial wastewater. By using 18S RNA and ITS sequences, the Penicillium commune AL5 strain that was isolated from Antarctic soil was identified. This study is dedicated to exploring its capacity to metabolize hazardous aromatic compounds. The strain showed very good potential in the degradation of hydroxylated monophenols and possessed exceptional abilities in terms of resorcinol degradation. The strain's ability to metabolize 0.3 g/L of p-cresol at 10 °C is notable. The strain is also capable of metabolizing LMW PAHs (naphthalene, anthracene, and phenanthrene) and eliminating all three tested compounds under 23 °C, respectively, 77.5%, 93.8%, and 75.1%. At 10 °C, the process slowed down, but the degradation of naphthalene continued to be over 50%. The quantity of PAH and a few significant intermediary metabolites were determined using GC–MS analysis. Sequencing of the enzymes phenol hydroxylase and catechol 1,2-dioxygenase revealed a close association with the genes and proteins in some fungal strains that can degrade the aromatic compounds examined thus far.


The crystallization of the α \|and β \|form crystals of syndiotactic polystyrene ( s PS) is determined by the crystallization temperature. Being crystallized at various temperatures from the melt, sPS forms the β form crystal at high temperatures above about 230℃, α form crystal at low temperatures below about 170℃ and a mixture of the α and β form at intermediate temperatures. The effect of different cooling rates is considered in more details. Since the β form crystallizes at high temperature from the melt.It will first crystallize during cooling.At low cooling rates,the crystalline phase of the β form has almost reached the maximum crystallinity of the sample by cooling to 230℃.So even the temperature for the α form formation is reached,there is no more crystallizable s PS portion remaining for the α form formation.That is the reason why the β form is always obtained by cooling at a slow or moderate rate.If cooling rate is high enough that the β form has almost no time to crystallize at high temperature,only the α form can crystallize at low temperature.That is the reason why only the α form crystal is obtained under quenching conditions.It clearly indicates that the crystallization temperature is the intrinsic factor controlling the formation the α \| and β \|form crystals.


Research concerning changes of chosen chemical el ements concentration in alluvial sediments was conducted in the lower cours e of the Obra river valley. The analyses of Fe, Mn, Cu, Zn, Ca, Mg and K concentration were don e in a fragment of vertical profile, which was characterized by variable lithology. On t he basis of statistical analysis (cluster analysis) an attempt was made to distinguish geoche mical groups of alluvial sediments of the Obra river valley. Six geochemical groups, which re present reductive conditions within peat deposits, the environment of flood sediments (inser ts of fine sands within peats and sandy silts in the top of the profile) and the environment of r ive bed sediments (fine sands in the bottom part of the profile), were singled out. Results of the study show that it is possible to distinguish the above mentioned depositional enviro ments on the basis of variations of sediments' chemical constitution.


Cationic guar gum and self-made chitosan were used as wet end assistants,and their effects on the Zeta potential,beating degree,dynamic filtration,single-pass retention,tensile strength and bulkness of reconstituted tobacco were studied in this paper.Results showed that compared with cationic guar gum,the influences of chitosan on Zeta potential,beating degree,dynamic filtration and single-pass retention were more obvious,and the higher of the deacetylation degree,the better of the results.All additives mentioned above could reduce reconstituted tobacco tensile strength and improve its bulkness,but the difference between them was small.Through orthogonal test,the application conditions of chitosan were optimized,as follows:the deacetylation degree of chitosan was 90%,the dosage of chitosan was 0.6%(based on bone dry stock quality),and the system pH was 6.
