In this doctoral thesis, contributions to the study and design of advanced controllers and their application to metallurgical smelting furnaces are discussed. For this purpose, this kind of plants has been described in detail. The case of study is an Isasmelt plant in south Peru, which yearly processes 1.200.000 tons of copper concentrate. The current control system is implemented on a distributed control system. The main structure includes a cascade strategy to regulate the molten bath temperature. The manipulated variables are the oxygen enriched air and the oil feed rates. The enrichment rate is periodically adjusted by the operator in order to maintain the oxidizing temperature. This control design leads to large temperature deviations in the range between 15oC and 30oC from the set point, which causes refractory brick wear and lance damage, and subsequently high production costs.
The proposed control structure is addressed to reduce the temperature deviations. The changes emphasize on better regulate the state variables of the thermodynamic equilibrium: the bath temperature within the furnace, the matte grade of molten sulfides (%Cu) and the silica (%SiO2) slag contents. The design is composed of a fuzzy module for adjusting the ratio oxygen/nitrogen and a metallurgical predictor for forecasting the molten composition. The fuzzy controller emulates the best furnace operator by manipulating the oxygen enrichment rate and the oil feed in order to control the bath temperature.
The human model is selected taking into account the operator' practical experience in dealing with the furnace temperature (and taking into account good practices from the Australian Institute of Mining and Metallurgy). This structure is complemented by a neural network based predictor, which estimates measured variables of the molten material as copper (%Cu) and silica (%SiO2) contents. In the current method, those variables are calculated after carrying out slag chemistry assays at hourly intervals, therefore long time delays are introduced to the operation.
For testing the proposed control structure, the furnace operation has been modeled based on mass and energy balances. This model has been simulated on a Matlab-Simulink platform (previously validated by comparing real and simulated output variables: bath temperature and tip pressure) as a reference to make technical comparisons between the current and the proposed control structure. To systematically evaluate the results of operations, it has been defined some original proposals on behavior indexes that are related to productivity and cost variables. These indexes, complemented with traditional indexes, allow assessing qualitatively the results of the control comparison. Such productivity based indexes complement traditional performance measures and provide fair information about the efficiency of the control system.
The main results is that the use of the proposed control structure presents a better performance in regulating the molten bath temperature than using the current system (forecasting of furnace tapping composition is helpful to reach this improvement). The mean square relative error of temperature error is reduced from 0.72% to 0.21% (72%) and the temperature standard deviation from 27.8oC to 11.1oC (approx. 60%). The productivity indexes establish a lower consumption of raw materials (13%) and energy (29%).


Professor Dunwoody regards media organizations to be community creatures; their accounts to be social constructions; and answers to, "Who's right?" to be relative.


Pseudoxanthoma Elasticum (PXE) is a rare genetic disease caused by a mutation of the ABCC6 gene, resulting in calcification of elastic fibers of the skin, eye and other organs and tissues that contain elastin. Because calcified arteries can bleed, hemorrhage from various organs is a reported complication of PXE. We conducted a literature review of all English language published articles reporting bleeding in patients with PXE. In this literature review, we identified 51 papers. Of those, 29 (57%) included at least 1 case of bleeding. Within these 30 papers, bleeding was reported in a total of 130 patients. Of the cases of bleeding, 113 occurred in the gastrointestinal tract, 12 occurred in the brain, 2 in the skin, 1 in the nose, 1 in the gums and 1 in the uterus. Clinicians and patients should be made aware of the risk of these significant complications, to facilitate preventive measures, prompt recognition and treatment.

We study the neutrino interaction rates in hot matter at high densities in the presence of uniform magnetic field. The neutrino cross-sections involving both the charged current absorption and neutral current scattering reactions on baryons and leptons have been considered. We have in particular considered the interesting case when the magnetic field is strong enough to completely polarise the protons and electrons in supernovae and neutron stars. The opacity in such a situation is considerably modified and the cross-section develops anisotropy. This has implications for phenomenon invoked in the literature to explain the observed pulsar kicks.


Google Ads is a Google's advertising system for advertisers bid on keywords in order to have their clickable ads appear in Google's search results. The quality of the selected keywords can directly affect the advertiser's bidding cost and advertising effectiveness. However, there are a few challenges for keyword selection, as listed below. First, the number of the keywords in an ad cannot be too big due to cost constraints. Second, there could be a mixture of different language in the keywords. Third, there is the imbalance issue between 'good' and 'bad' keywords. Fourth, the effect of the typical keyword classification approach cannot produce satisfactory result. In this study, the evolutionary algorithm and deep learning are combined to deal with these challenges. By using word embedding to represent the keywords, choosing the appropriate corpus to handle the problem of mixed text with different languages, re-sampling to deal with data imbalance problem, using PSO to optimize the CNN structure and adding keyword-related features to improve classification effect, these difficulties are cleverly overcome. Finally, the keyword selection problems are successfully solved. This study is of great significance to the reduction of advertising investment cost and the increase in advertising efficiency.


The purpose of this research is to understand whether the International Automotive Task Force (IATF) 16949 certification for the automotive sector facilitates the implementation of Lean Six Sigma (LSS) tools and methodologies. Moreover, the research evaluates to what extent the LSS tools and methodologies are implemented by companies through the IATF standard. The results of a seven-item questionnaire based on seven hypotheses derived from a review of the IATF 16949 standard were tested. The online questionnaire was completed by 135 Italian practitioners. Italy has about 1500 automotive-related companies that are IATF 16949 certified and has a tradition in terms of the automotive industry. The results from the questionnaire were augmented by the respondents' notes. The results indicated that 16949 does not facilitate the implementation of Design for Six Sigma and Six Sigma in general or the Single Minute Exchange of Die tool and Total Productive Maintenance methodology. On the other hand, the respondents' indicated that IATF 16949 had a strong effect on the implementation of the problem-solving methodology, and it affected 5S and other tools as well as tools for improving material flow management. Some particular considerations concerning how companies are obliged by the standard and customers to implement LSS tools and methodologies emerged.


Last year Dr. Turpin wrote to the Journal, seeking assistance in recruiting Australian doctors for his work. Because registration requirements in Hong Kong come within the ambit of the General Medical Council in Great Britain, the registration of American doctors in that city can present practical difficulties. It is much simpler for Australians, and for this eminently practical reason Dr. Turpin turned his eyes in our direction. We are not aware that the appeal brought an effective response, but perhaps "Operation Concern" this year will do better. Dr. Turpin will be visiting Australia as the guest of the Australian Junior Chamber of Commerce during the next month. He is scheduled to arrive in Perth on April 8, to make a rapid tour of all States, leaving Sydney on May 5. Details of local visits may be obtained from local Junior Chambers of Commerce, which will be pressing the claims of the operation in their own areas.


In the wonderful television series 'Yes, Minister', the buffoonish title character Jim Hacker advanced his policy responses to the crises of the day by shouting 'Something must be done! This is something. Therefore we must do it'. In terms of alcohol-related problems, particularly in the UK, there is widespread agreement that 'Something must be done'. Both the public and the newly elected coalition government are deeply concerned about alcohol's role in yobbism, auto accidents, family breakdown, and rising health care costs, amongst other problems. Many UK public health advocates believe the way forward is minimum pricing of alcohol, a proposal which very nearly passed the Scottish parliament in June 2010. Into these works comes a spanner lobbed by Dr Moore (this issue, Moore, 2010). Moore argues that alcohol-specific control policy has substantial potential to inflict more rather than less damage on society because heavy drinkers may respond by increasing consumption of other more dangerous intoxicating substances, or by switching to other forms of alcohol that are cheaper but more dangerous (e.g. from beer to fortified wine, high-strength spirits, or moonshine). In this commentary, I agree with several of Moore's central insights but question his more general pessimistic stance towards alcohol-specific control policies.

To begin with points of agreement, Moore and I are both impressed by the scientific literature establishing that policy-makers can usually put downward pressure on the level of alcohol consumption in a society by increasing price (Cook, 2007). I admire Moore's unwillingness to simply end the argument at that point a la Jim Hacker, and instead raise the question of whether there might be unintended and unappreciated consequences to such policies. He quite rightly notes that there are many intoxicants available other than alcohol, and that some drinkers use these substances as complements (something that accentuates the desired …


Democratic innovations, variously described as 'empowered participation' or 'civic innovation', are designed to increase and deepen citizen participation in the decisions that affect them directly. This chapter reviews current understanding of participatory processes such as citizens' assemblies, citizens' juries, deliberative polling, participatory budgeting, study circles, town meetings, and online dialogues; and considers their impact along with an analysis of the implications of different participatory designs on democratic qualities and policy outcomes. One of the limitations of the burgeoning literature on democratic innovations is the tendency to focus on exemplary cases, which often underplays the variety of conditions that need to be in place for the success of these forms of public engagement. Close attention is given to the different approaches taken with participatory budgeting and randomly selected mini-publics in diverse contexts, to illustrate both the substantial potential of democratic innovations to improve democratic politics and their vulnerabilities to misapplication.


Background . Usability testing of medical devices are mandatory for market access. The 39 testings ' goal is to identify usability problems that could cause harm to the user or limit 40 the device's effectiveness. In practice, human factor engineers study participants under 41 actual conditions of use and list the problems encountered. This results in a binary 42 discovery matrix in which each row corresponds to a participant, and each column 43 corresponds to a usability problem. One of the main challenges in usability testing is 44 estimating the total number of problems, in order to assess the completeness of the 45 discovery process. Today's margin -based methods fit the column sums to a binomial 46 model of problem detection. However, the discovery matrix actually observed is 47 truncated because of undiscovered problems, which corresponds to fitting the marginal 48 sums without the zeros. Margin-based methods fail to overcome the bias related to 49 truncation of the matrix. The objective of the present study was to develop and test a 50 matrix-based method for estimating the total number of usability problems. 51 Methods . The matrix-based model was based on the full discovery matrix (including 52 unobserved columns) and not solely on a summary of the data (e.g. the margins). This 53 model also circumvents a drawback of margin-based methods by simultaneously 54 estimating the model's parameters and the total number of problems. Furthermore, the 55 matrix-based method takes account of a heterogeneous probability of detection, which 56 reflects a real-life setting. As suggested in the usability literature, we assumed that the 57 probability of detection had a logit-normal distribution. 58 Results . We assessed the matrix-based method's performance in a range of settings 59 reflecting real-life usability testing and with heterogeneous probabilities of problem 60 detection. In our simulations, the matrix-based method improved the estimation of the number of problems (in terms of bias, consistency, and coverage probability) in a wide 62 range of settings. We also applied our method to five real datasets from usability testing. 63 Conclusions . Estimation models (and particularly matrix-based models) are of value in 64 estimating and monitoring the detection process during usability testing. Matrix-based 65 models have a solid mathematical grounding and, with a view to facilitating the decision- 66 making process for both regulators and device manufacturers, should be incorporated 67 into current standards.

A new integral equation for the two-body eorrelation function is derived for Fermi systems in the framework of correlated basis-function. The exchange characteristics of fermions are considered in detail according to the topological structure at the vertices of correlation bonds. The only approximation used is the Kirkwood superposition approximation and its extention. Since decomposition into various exchange parts is known, the three forms of the kinetic energy test can be obtained in this new Chakravarty-Woo formalism.


Apache Kafka, which is a high-throughput distributed message processing system, has been leveraged by the majority of enterprise for its outstanding performance. Unlike common cloud-based access control architectures, Kafka service providers often need to build their systems on other enterprises' high-performance cloud platforms. However, since the cloud platform belongs to a third party, it is not necessarily reliable. Paradoxically, it has been demonstrated that Kafka's data is stored in the cloud in the plaintext form, and thus poses a serious risk of user privacy leakage. In this paper, we propose a secure fine-grained data transmission scheme called Secure Door on Cloud (SDoC) to protect the data from being leaked in Kafka. SDoC is not only more secure than Kafka's built-in security mechanism, but also can effectively prevent third-party cloud from stealing plaintext data. To evaluate the performance of the SDoC, we simulate normal inter-entity communication and show that Kafka with SDoC integration has a lower data transfer time overhead than that of Kafka with built-in security mechanism opened.


Once upon a time, a Professor of European Institutions, at least if a lawyer by training, could simply assert that the European Communities are based on the rule of law, that they create institutions with autonomous powers, which are able to issue legislation binding as law throughout every member State of the Community, and that they create courts which have power to exercise judicial control over a complex network of relationships between the Community institutions, the member States and private citizens. While these statements are still true, however, they must now be laced in a rather more complex context. Furthermore, there is a contrast between on the one hand the intensification (to borrow a word from the Common Agricultural Policy) of certain fundamenta s of the EC legal order in the recent case law of the European Court, and on the other hand attempts by member States to escape this through non-EC forms of cooperation in the framework of the European Union, the development of the idea that not all the rules of the EC Treaty apply to all the member States, and the entry by the majority of the member States into a separate Treaty, the Schengen Agreement, dealing with matters which might be thought to fall under the EC Treaty or the Home Affairs and Justice pillar of the Treaty on European Union—all of which might generically be referred to as variable geometry. In the other direction, it may be observed that large amounts of substantive


The physical properties of rocks, in the crystalline mass of the Voronezh anteclise, were studied. The study of the physical properties of rocks is important for the improvement of geophysical methods for mapping crystalline rocks in the foundation and exploration of different geological objects which are associated with the crystalline foundation, covered by the sedimentary mantle. It is found that: (1) rocks in the crystalline foundation are very different in physical properties; (2) the physical properties are closely related to their substance composition and genesis; (3) petrographic properties give clues of rock afficiation to certain complexes; and (4) physical and magnetic properties should be examined by petrography, chemical and X-ray analysis.


Objective:To explore the application value of color Doppler tissue imaging(DTI) in children with anemia.Methods:The velocity of mitral valve ring and the left ventricular posterior myocardial wall in systole and early diastole(MVR-SV,MVR-DEV,MSV,MDV) was observed by using DTI in 25 children with anemia.The function of left ventricle include cardiac index(CI) and ejection fraction(EF) was measured combined with M-Doppler.Each was compared with the paired control group dynamically.Results:CI and MVR-SV of the first group were significantly higher than the control group(P0.05).MVR-DEV and MDV of the second group were significantly lower than the control group(P0.05).Conclusion:DTI technology could observe cardiac function of the children with anemia,and it is a sensitive and reliable referential criteria in evaluating cardiac function.


By use of monoclonal antibodies cross-reactive with Marek's disease virus and herpesvirus of turkeys, three glycoproteins (for Marek's disease virus, gp115/110, gp63, and gp50; for herpesvirus of turkeys, gp115, gp62 and gp52) related to virus neutralization were identified. Immunization of chickens or rabbits with these glycoproteins purified by affinity chromatography resulted in production of neutralizing antibodies.


Mature B cells are grouped into two major subsets, B‐1 and B‐2, believed to derive from separate lineages. We have recently shown that B‐1 cells, which are characterized by CD5 surface expression, specifically exhibit significant levels of the tyrosine kinase Lck in man. Here we show that also in mice Lck expression is restricted to B‐1 cells and address the potential role of Lck in B‐1 cell development and activation. Using as a model an Lck–/– mouse, we show that, while dispensable for B‐1 cell development, Lck is required for full and sustained activation of the tyrosine phosphorylation and MAP kinase cascades triggered by the BCR in CD5+, B‐1 cells. The data suggest a potential role for Lck in the achievement of the higher activation threshold required for productive BCR signaling in B‐1 as compared to B‐2 cells.


Abstract The turbine blades play a crucial role in the efficiency of the steam turbines system, which can also lead to safety and economic implications in a catastrophic failure. The propagation of fatigue cracks is a relevant issue, especially if there are safety issues involving human life or the environment or significant economic losses. This work investigated the failure of a turbine blade of a 25 MW cogeneration power plant. One found several deformation marks and debris in the primary crack origin at the blade's base. They were responsible for the fretting fatigue type wear. The blade material matches the composition of X20CrMo13 steel; however, the hardness shows a higher average value (250±4.7) than typical standard values of 220–240 HB.


The present investigation was carried out using 191genotypes as mini core collections of pigeonpea along with 5 check varieties to know the genetic diversity at molecular level. Significant variation was observed by the way of analysis of variance for nine characters viz., days to 50% flowering, days to maturity, plant height, number of branches per plant, pod bearing length, number of pods per plant, number of seeds per pod, seed yield per plant and hundred seed weight. Molecular diversity using 18 polymorphic simple sequence repeat (SSR) markers divided genotypes into 15 clusters, of which ICP11059 and AK-101 were solitary, indicating their distinctiveness among all genotypes. Similarly, BSMR-533, JKM-7, RVK-285, ICP-1126, ICP-348, ICP-6859 and ICP-7869 were found distinct among the genotypes. Geographical origin based diversity separated Indian and non Indian genotypes. The Un weighted Pair Group Method with Arithmetic mean (UPGMA) based dendrogram indicated distinctiveness of ICP-13633 and Bennur local, as they formed solitary cluster. The SSR marker CcM 602, as it could differentiate 4 genotypes at different base pair size can be used for identification and finger printing of genotypes.


Delinquent CRE loans began to surface soon after the pandemic started and remain elevated in 2021. Broad loan delinquencies would represent a potential threat to bank capitalization and solvency, particularly for smaller banks that tend to have higher concentrations in CRE lending. Collateral and loan performance have varied significantly by property type during the pandemic. However, regulators do not collect information on CRE exposures by property type at smaller banks, which limits our insight into the systemic implications of CRE exposures at these firms.


Socioeconomic status (SES) influences health, behaviors, and well-being. Emerging information suggests that SES effects on health may be in part be due to SES effects on brain development. We have conducted a mini review of U.S.-based studies examining SES effects on brain development to synthesize the existing knowledge on what brain structures and functions show large and consistent SES influences. We have reviewed SES effects on performance in various cognitive functions such as learning, memory, and language. Additionally, we have reviewed the emerging literature from the Adolescent Brain Cognitive Development (ABCD) study on the effects of social marginalization in reducing the effects of SES on children and youth brain development. These diminished returns of SES in minoritized youth are not due to genetics; rather, we argue that they stem from systemic and structural racism, social stratification, and marginalization that generate inequalities across the SES spectrum. As a result of these diminished returns, inequalities expand from low-SES to mid- and high SES sections of US society.


Mountain hillslopes are dynamic settings with discontinuous soils affected by a suite of variables including climate, lithology, hydrology, and vegetation. Our study seeks to understand how forest cover influences soil and rock distribution at decadal to century timescales. We focus on a series of post-glacial hillslopes in Lost Horse Creek of the Bitterroot Mountains, Montana. In this system, avalanche paths maintain parallel, topographically similar swaths of forested and non-forested slopes with uniform aspect, lithology, and climate. We combine field observations, fallout radionuclide analysis (Pbex & Cs), and remote sensing data to understand both landscapeand fine-scale patterns in soil and rock distribution. Local soil and rock measurements indicate more extensive soil cover (forest = 94.4±2.6%; non-forest = 88.3±1.9%) and thicker soils (6cm greater median) in the forested system. We compare landcover-classified rock to topographic metrics from LiDAR data and find a doubling of rock cover (from 40% to 80%) as hillslope angles transition across slopes of ~24-42o. Topographic roughness, calculated as the standard deviation of slope, is predictive of only ~60% of total landscape rock cover, but can identify large boulders and coarse-scale outcrops with higher accuracy (79%). These calibrated remote sensing metrics indicate higher rock cover in non-forested regions (34%, compared to 20% in forested areas), though with high uncertainty. Additionally, we measure fallout-radionuclide inventories in soils to explore variations in decadal transport processes and soil residence times. We find distinct Pb and Cs behaviors in forested and non-forested systems, controlled both by unique partitioning of each nuclide within organic and mineral soil horizons, but also due to depth-driven differences in their physical mobility. Average Pbex inventories in non-forested soils are 33% lower, and half as variable as soils in the forested region (10.45±0.97 and 15.49±1.91 kBq/m respectively), while Cs inventories are indistinguishable (4.04±0.34 and 3.73±0.42 kBq/m). Together, our spatial, field, and isotope analyses suggest forested systems have greater soil storage and longer residence times than non-forested soils, mediated by differences in surface erosion processes within a larger fire disturbance landscape.


Lex and Yacc are used to analyze the Lexis and grammar of the languages defined by context-free grammars,and an independent information extracting module is built to extract the information of source files for white-box testing.The whole grammar system for a tested language accorded with the criterion of Yacc is built,and the system is logically divided into two primary parts,class grammar and function grammar.Sentence structure and sentence linked list structure express the function definition using block and level when they extract function information.The structure information is put into the database to be used for other modules,thus the modules are completely independent.In this way,only need to design different information extraction modules,various context-free grammar languages for white-box testing can be realized.


This article introduces a conceptual model for understanding how young women perceive the current challenges of leadership. Numerous studies and articles claim that women are better educated, more experienced, and better suited for leadership positions than ever before. This news is encouraging, but the number of women in leadership roles in American politics gained less than one percentage point this year, hovering around 22%, while in the private sector many organizations have yet to place a single woman on their board. The proportion of women on corporate boards is 16%, with no evidence that this is likely to grow in the near future. What is even more discouraging is that these low numbers are not significantly higher than those in many developing nations. It is evident that women are underrepresented in top leadership positions and must intensely challenge the status quo. This article presents results of a study based on in-depth interviews with college women who are seeking paths to leadership. The researchers employ qualitative analytical research tools to explore the complexities of the phenomena. The findings bring a greater understanding of the antecedents and consequences that lie beneath the challenges affecting the next generation of women leaders.

Organic manures and biofertilizers application in the nutrient management programme is inevitable for achieving sustainable sugarcane production. Application of farmyard manure, cane trash, pressmud, vermicompost. and biocompost in combination with recommended inorganic fertilizers have recorded increased cane yield over inorganic fertilizer alone, besides improving the soil fertility and economizing the cane production. Intercropping and incorporation of green manures such as daincha, sunhemp and cowpea and pulses like greengram, blackgram, lentil and frenchbean have established beneficial effects of improving nitrogen use efficiency, cane yield and improving the physio-chemical properties of soil. Nitrogen fixing biofertilizers are useful to economise the nitrogenous fertilizers and to increase the cane yield. Phosphorus solubilising biofertilizers solubilize the unavailable phosphorus to available P form and increase the P use efficiency. Inclusion of biofertilizers in the nutrient management programme has found to increase the yield of sugarcane by 5–10%, besides increasing the nutrient use efficiency.


The Care Quality Commission's latest resource outlines the ways in which they expect care to be provided to meet diverse needs. Amanda Halliwell identifies what care homes need to do.


To understand what they read or hear, children and adults must create a coherent mental representation of presented information. Recent research suggests that the ability to do so starts to develop early –well before reading age- and that early individual differences are predictive of later reading-comprehension performance. In this paper, we review this research and discuss potential applications to early intervention. We then present two exploratory studies in which we examine whether it is feasible to design interventions with early readers (3 rd grade) and even toddlers (2-3 years old). The interventions employed causal questioning techniques as children listen to orally presented, age-appropriate narratives. Afterwards, comprehension was tested through question answering and recall tasks. Results indicate that such interventions are indeed feasible. Moreover, they suggest that for both toddlers and early readers questions during comprehension are more effective than questions after comprehension. Finally, for both groups higher working memory capacity was related to better comprehension.


The city of Puebla is one of the 34 sites in Mexico recognized by UNESCO under the declaration of cultural heritage of humanity, in 1987 got the recognition for its historical and cultural legacy, fulfilling 29 years in 2016; however, despite the actions taken by several government levels, faith has faced in different moments serious problems that in more than one occasion have put in predicament the designation. Some of the problems are: the lack of culture on heritage by citizenship and the lack of knowledge about the title of Puebla as a "world heritage city", which generates indifference and neglect until the conscious abuse of the monuments area; which together with the lack of public resources for the appropriate maintenance, becomes a threat to the area and its preservation for the future generations; in this sense; this research carried out an integral analysis on citizen perception of the human heritage, and concretely analyzes the case of Puebla city, Mexico; seeking information that allows to make recommendations to join the local, national and international efforts.


US treasury bonds held by China pose a key issue in the political and economic relationship between the two countries.Theoretical analyses indicate such economic factors as growth of China's GDP,expansion of China-US trade imbalance,the appreciation of RMB against US dollar and positive yield rate of US treasury bonds all cast a favorable influence on the size of US treasury bonds held by China.As is supported by the quarterly data from 2001 to 2009,there is a positive influential mechanism of the first three economic factors on US treasury bonds held by China;and once RMB revalues and the bilateral political relationship between China and the US deteriorates,the size of US treasury bonds held by China will shrink.China's decision to buy US treasury bonds is of a dual quality:economic and political.

Three-dimensional video has recently gained great popularity as it enhances the viewing experience. Streaming of 3D video over IP networks will soon become a common means of multimedia consumption, thanks to the recent standardization efforts such as MPEG-DASH and 3D-HEVC. To this end, rate adaptation techniques are required to overcome the unreliable nature of IP networks. In this paper, we propose a rate adaptation approach for streaming multiview plus depth (MVD) video by exploring the effects of the number of views and the quality of views on the quality of experience. Specifically, we show that concurrently decreasing the distance between virtual camera positions and reducing the number of views help maintain an acceptable perceptual quality level when the network resources are scarce.


The present study investigates the suitability of a HypoGel support bearing oligomeric poly(ethylene glycol) (PEG) chains to act as an insoluble carrier for grafted organotin catalysts. Through the introduction of polar spacers, an improved swelling and site accessibility in the polar media typically involved in transesterification reactions are targeted. Advanced structural investigation shows that quantitative conversion into the targeted HypoGel-supported organotin trichloride is hampered by the existence of intra- and/or intermolecular donor-acceptor OSn interactions caused by the presence of donor moieties in the PEG-linker. Support is provided to the proposal that the latter interactions are at the origin of the moderate catalytic performance displayed by these HypoGel-supported catalysts, achieving only 41% conversion after 2 hours in the transesterification of ethyl acetate and n-octanol. In contrast with similar organotin catalysts supported by an alkyl spacer, the HypoGel-supported materials appear to be poorly recyclable and display poor leaching resistance.

Cargo handling appears to be the fundamental function of ports. In this context, the question of type of equipment and capacity rate need to be tackled with respect to cargo handling principles. The purpose of this study is to discuss the types of equipment to be used in ports, relating the matter to costs and capacity. The question is studied with a basic economic theoretical approach. Various conditions like port location, size, resources, cargo traffic, ships, etc. are given parameters to dictate the type and specification of the cargo handling equipment. Besides, a simple approach in the context of cost capacity relation can be useful in deciding whether to use specialized or flexible equipment. Port equipment is sometimes expected to be flexible to handle various types of cargo as many as possible and sometimes to be specialized to handle one specific type of cargo. The cases that might be suitable for those alternatives are discussed from an economic point of view in this article. Consequently, effectiveness and efficiency criteria play important roles in determining the handling equipment in ports Keywords: Port, Flexibility, Specialization, Cargo handling equipment

The article presents the author's vision of the way to solve the problem of values' formation in future teachers in conjunction with the development of their professional competence. It is proved that inclusion of students into project activity during their teaching practice is aimed at stimulating the reflection of their own values, the awareness of the values of pedagogical work, reorientation or correction of values of some students and strengthening and development of professionally significant values in others.


Apparently everybody is keen on understanding the reasons for human conduct. However numerous researchers and the overall population embrace reasons for conduct that have coherent blemishes. Crediting conduct to mental occasions, feelings, character, or unusual character, regularly, is submitting one of various normal blunders, like reification, roundabout thinking, or ostensible paradoxes. An undeniably continuous blunder is accepting hereditary clarifications of conduct without a recognized quality.

Recent developments in bleaching with hydrogen peroxide, peracetic acid, and sodium chlorite are discussed against the background of current bleaching problems. A comparison of the properties and behaviour of the bleaching agents is given. Methods of desizing with persulphates are described, as well as a new process for bleaching cotton at a pH below 7 with a dilute solution of peracetic acid. The use of a commercially available concentrated solution of sodium chlorite is described.

In this paper, a method is proposed to automatically identify or retrieve parameters of an energetic model of servers in Internet DataCenters (IDC). Using historical measurements of power consumption and Informatics Technology (IT) load, the parameters of server model are identified as defined in previous publications. This identification is used to introduce the correct model of server in a global optimal energy management system of IDC. This work is part of a bigger three years project, called EnergeTIC, which aim is to optimize the energy consumption of a global IDC, taking into account all its components, from servers to their cooling systems.

Acrylamide was polymerized by electrochemical oxidation in glacial acetic acid medium containing sodium acetate. The influence
of monomer concentration and current density on polymerization were examined. The polymerization is possibly initiated
by the species produced by the anodic reaction of the supporting electrolyte. Introduction of hydroquinone into the
system prevents the formation of polymer, indicating a free radical mechanism. Influence on the addition of ferric salt on
polymerization was also examined. Molecular weight of the polymer has been examined by viscometry method. The chain
structure of the polymer has been identified by I R spectrum of the polymer


The general view is that the ancient Indian epic Ramayana was introduced to the Dai ethnic area of China with the introduction of Buddhism. Buddhism was introduced to the Dai ethnic area on a small scale at the beginning of the century or earlier, and Ramayana was also introduced to the Dai ethnic area at the same time or earlier. In fact, the commercial and cultural exchanges between China and ancient India were much earlier than this time. Before Buddhism was introduced, Ramayana might have been introduced to the Dai ethnic area. There are three routes for the introduction of Ramayana to the Dai ethnic area. The first route is to spread it by sea from southern India to Indonesia, Thailand, Burma, Laos and northern Vietnam, and then to the Dai ethnic area in Yunnan. The second route is from northern India to Tibet, China, and then to the Dai ethnic area through the Sichuan-Tibet highway. The third route is from the land through Bangladesh to Myanmar to the Dai ethnic area in Yunnan. The third route is the Sichuan-Yunnan-Burma-India Passage, a branch of the South Silk Road, and it is also a passage for direct exchanges between China and India without going by sea. The literature records that this passage was opened in the 4th century BC at the latest, but it didn't get the due attention in the academic circle for a long time.


There has been considerable debate in the scientific literature concerning the significance of the risks associated with exposure to chrysotile asbestos (Mossman et al., 1990; Stayner et al., 1996). This paper presents the findings from exposureresponse and risk analyses of lung cancer and asbestosis mortality based on a cohort mortality study of U.S. textile workers exposed to chrysotile asbestos.


We evaluated effects of reduced hourly variation in flow from Glen Canyon Dam on survival of age-0 rainbow trout (Oncorhynchus mykiss) in the Colorado River, Arizona, USA, based on monthly abundance estimates. The proportion of the age-0 population in low-angle shorelines, which are potentially more sensitive to flow variability, declined from 70% in June to 20% in November as fish grew and made an ontogenetic habitat shift to deeper habitat. Average daily instantane- ous mortality between August and September was 0.008 units lower in years when there was no change in the minimum flow compared with years when there was a sudden 50% reduction in the minimum flow. However, mortality was 0.006 units higher during the fall when there was no hourly variation in flow compared with years when flows fluctuated. As a re- sult of these opposing patterns, 3-month age-0 survival across steady (0.31) and unsteady (0.28) flow regimes were very similar. While additional replication is required to strengthen inferences about effects of steadier flows, we demonstrate the utility of early life history monitoring for evaluating effects of flow management on fish populations in regulated rivers.

The dark matter in Universe, its class and candidates, and the significance of observation are briefly described. The methods and results and its progress of detection for the cold dark matter particles are reviewed, in particular, the observation of DAMA collab. (Beijing-Rome) gives the new limit on WIMP search and the first annual modulation signature: [S-m] = 0.037 +/- 0.008 cpd/keV.kg, the estimated WIMP mass = 60GeV/c(2). It is possibly the hint of the existence of WIMP.


The use of a single inclined hot wire for measurments of mean flow velocity and direction in a three−dimensional turbulent flow field is presented. A constant temperature hot−wire anemometer circuit is used with and without a linearizer. The use of the linearized results were found to improve the readout ability of the instrument and also to simplify the correction for directional measurements. A study of the effect of turbulence levels on the steady calibration results has shown that if the turbulence levels and the cross correlations are known, corrections can be applied to obtain angles and velocities as reliable as those obtained from a directional pressure probe. The advantages of the use of the hot wire over a pressure probe are that the hot wire has much faster response, disturbs the flow field to a lesser degree, is easier to correct for turbulence levels, and due to its smaller dimension compared with the pressure probe is less erratic concerning mean velocity gradients. The method of measurement...

Plant organelles emit signals that regulate the expression of nuclear genes, a process known as retrograde signaling. The chlorophyll intermediate Mg-protoporphyrin IX (Mg-ProtoIX) is one such signal that accumulates under stress conditions and acts as a negative regulator of photosynthetic gene


Objective — To investigate whether isolated congenital ductus arteriosus aneurysm (DAA) is caused by loss of function of mutations in the elastin gene (ELN), we screened the elastin gene, which has been proposed as a candidate gene in DAA. Methods and results — A total of 2249 full-term neonates received echocardiographic screening. Newborns with isolated DAA were divided into two groups: those with large DAA (≥10mm) and small DAA (<10mm). ELN gene study was performed randomly for newborns with DAA. There were 186 (8.3%) newborns with DAAs. Among them, 29 had large and 157 had small DAA detected by 2DE. Maximum internal diameter of the DAAs ranged from 6.6 to 14.0mm (8.3±1.2mm). All cases were asymptomatic. Fifteen newborns with large DAA and 14 with small DAA received ELN gene analysis. Among them, 4 infants had single nucleotide variations, including nucleotide 212 C→T in 2, 278 C→T in one, and 1232 T→C in one.We considered the possibility that these might be a neutral single nucleotide polymorphism rather than a mutation. Conclusions — The incidence of congenital DAA and clinical presentations were consistent with those of our previous report. Based on our findings, the ELN gene can be excluded as a candidate gene in DAA.We consider the presence of DAA may be a normal variant of ductus arteriosus in full-term infants.

The text considers the anthropological consequences of living in the digital, postmodern age and their effects on the education system and culture. In accordance with an immeasurable role of art education in personality development, we speak of art as the highest expression of human creativity. The contemporary, dominantly technical, development of science, being detached from culture, has an important influence on both school and university education. We point to transdisciplinarity as a possibility for integrative research, reconciliation of science(s), arts and spirituality, with the aim of incarnating human beings. The unfavorable impact of the information abundance in which the generation of "digital natives" is growing up is reflected in the increasingly dangerous disproportion between technological and anthropological potentials.


Introduction: The long-term care in schizophrenia patients can cause care burdens, which will relate to the family's decision to do pasung. The perceived burden will be even heavier because of the COVID-19 pandemic. This review aims to identify the family care burden affecting pasung in schizophrenic patients during the COVID-19 pandemic.  Methods: This scoping review was conducted by searching four databases, namely ProQuest, Science Direct, and EBSCO, and Google Scholar in the past ten years. This study uses the PRISMA 2009 protocol in filtering articles from the database. Researchers summarize based on the significance value for quantitative research, based on themes' qualitative research, and discussed factors mentioned which may influence the family. Thus, we obtained 15 articles for final review.  Results: The results obtained that the subjective burden felt by the family is a feeling of worry and sadness due to the patient's aggressive behavior and the safety of the patient, family, and environment. The objective burdens most felt by families are financial burdens, both medical costs, transportation to reach mental health services, and the cost of daily living. The COVID-19 pandemic will affect both types of care burdens, thereby affecting the quality of care for families with schizophrenia patients in pasung.  Conclusion: Schizophrenia patients are one of the populations that are vulnerable to COVID-19. Nurse plays a role in the ability to overcome the burden of schizophrenia care and improve adaptation to the current pandemic to create optimal mental health in the community.


This paper describes an unsupervised algorithm, with no language-specific knowledge, which takes a list of morphological paradigms and explores crossparadigmatic structure in terms of two computational tasks: alignment and clustering. Based on complexity computation in a minimum description length approach, the proposed algorithm learns the relationship across the paradigms based purely on surface strings and formalizes the intuitive idea that, for instance, jumping and loving belong to the same morphological category – this is alignment. Moreover, the algorithm simultaneously learns morphological groupings of the paradigms akin to conjugation and declension classes – this is clustering. The clustering analysis also reveals more fine-grained hierarchical structure among the inflectional classes. The algorithm is applied to verbal paradigms from English and Spanish. The results are useful for further work on the unsupervised learning and prediction-oriented research of paradigmatic structure. We also show the value of computational techniques in linguistics for both explicitly evaluating competing analyses and rigorously implementing analyses.

Crystal structure of mono-β-alaninium chloride has been studied by single crystal X-ray diffraction. The compound crystallizes in the orthorhombic system. The space group is Pbca , with the following lattice constants: a  = 9.7414(5) A, b  = 7.4671(6) A, c  = 16.5288(11) A, V  = 1202.31(14) A 3 , Z  = 8. The asymmetric unit contains one β-alaninium cation ( + NH 3 CH 2 CH 2 COOH) and one chloride anion. The structure was shown to consist of layers stacked along the c -axis and connected with each other by weak van der Waals forces. Each layer consists of two halves linked by hydrogen bonds between carbonyl and NH 3 + groups and, also, between NH 3 + groups and Cl - anions. Fourier transform infrared spectrum of β-alaninium chloride was recorded and analyzed. The spectroscopic results were found to support the conclusions of the structural study.

Water flooding system itself is a major energy consumption.Moreover,as the moisture content of the integrated oilfield increases,the energy consumption of water injection will also rise sharply.Therefore,the energy saving of water injection system is of great significance in lowering the cost of oil production.


Abstract In a cold case investigation of a 1983 homicide, trace amounts of soil were identified on a 10-year-old victim's pyjama top. Swatch samples were cut from the pyjama top, specifically the hem, to determine the provenance of this questioned soil. A comparative study was undertaken of the questioned soil with control soils from the Onkaparinga estuary using morphological observations with the naked eye and scanning electron microscopy (SEM), chemistry, traditional laboratory X-ray diffraction (XRD) and synchrotron µ-XRD. Synchrotron µ-XRD with high-intensity X-rays provided greater sensitivity and resolution than the laboratory XRD source to identify pyrite and clay minerals on the pyjama top. SEM confirmed that these mineral particles are deeply impregnated in gaps between fibres of the fabric, which are likely to have originated under water with force being applied on the pyjama top – implying that the victim was pushed into the mud. This is substantiated by transference shaking experiments, where mineral particles are dominantly located on the surface of the fabric. The questioned soil samples have a moderately strong degree of comparability with the control hypersulphidic subaqueous soils containing pyrite in the Onkaparinga River estuary – providing evidence that the soils have similar origins. The accused was found guilty by a Supreme Court judge of murder.

The African Odyssey project focuses on studying the migration of the black stork Ciconia nigra breeding at a migratory divide. In 1995� 2001, a total of 18 black storks breeding in the Czech Republic were equipped with satellite (PTT) and VHF transmitters. Of them, 11 birds were tracked during at least one migration season and three birds were tracked repeatedly. The birds migrated either across western or eastern Europe to spend the winter in tropical west or east Africa, respectively. One of the juveniles made an intermediate route through Italy where it was shot during the first autumn migration. The mean distance of autumn migration was 6,227 km. The eastern route was significantly longer than the western one (7,000 km and 5,667 km respectively). Important stopover sites were discovered in Africa and Israel. Wintering areas were found from Mauritania and Sierra Leone in the west to Ethiopia and Central African Republic in the east and south. One of the storks migrating by the eastern migration route surprisingly reached western Africa. Birds that arrived early in the wintering areas stayed longer than those arriving later. On the average, birds migrating via the western route spent 37 d on migration compared to 80 d for birds migrating via the eastern route. The mean migration speed in the autumn was 126 km/d and the fastest stork flew 488 km/d when crossing the Sahara. The repeatedly tracked storks showed high winter site fidelity.


The ion fluctuation axial profile is measured by Thomson scattering in an inhomogeneous laser-produced plasma. The electron temperature and plasma drift velocity at the location of the measured ion waves and the plasma density profile are simultaneously measured. The measured ion fluctuation profile is compared to the profile predicted by convective growth of the stimulated Brillouin scattering instability calculated from the measured hydrodynamic profiles.


The large-scale restriction policy in the Covid-19 Pandemic has caused society activity paralyzed, it caused a serious problem in the economy. The problem occurred such as low peoples' income resulted in low purchasing power. This study utilized a qualitative descriptive method. The pre-employment card is a bridge that was able to connect people with a variety of new skills training, in addition, the government also hoped to create a society to be more capable and empowered to simultaneously reduce excessive dependence on others. Access facilities to various kinds of tutorial training videos, as well as cash assistance provided by the pre-employment card program. The Pre-employment card program was expected to be able to create jobs, so that, the income increased because of the higher a person's income, the higher his/her purchasing power and the more diverse needs to be filled, and vice versa. The result in this research affected the low purchasing power during the Covid-19 pandemic cannot be overcome through pre employment allowance due to careless society on trainings in developing skills. The people only accentuated the allowance to directly used effortlessly to add the nominal allowance.


One handred and eight heads of crossbred Duroc×Landrace×Yorkshire piglets were selected randomly and divided into 9 treatments(3 duplicates per treatment,4 piglets per duplicate with the male/female 1∶1) to evaluate the effect of wheat ratio(0%,25%,50%) and NSP enzymes supplementation(0,0.025%,0.05%) on nutrient digestibility and rectal pH and microflora of growing pigs by 2×3 factorial design.The results showed that:(1)Dietary wheat ratio had significant effects on nutrient digestibility and rectal pH and microflora of growing pigs(P0.05).Digestibility of CF,CP,DM and GE for growing pigs decreased by 23.10%(P0.05),16.50%(P0.05),13.14%(P0.05),8.66%(P0.05) and rectal Bifidobacterium and Lactobacilluys numbers decreased by 31.95%(P0.05),35.46%(P0.05),respectively,but rectal E.coli and Salmonella numbers were 173.84%(P0.05),156.81%(P0.05) higher in diet Ⅲ with 50% wheat than in diet Ⅰ without wheat respectively. There were significant differences between diets with 25% wheat and diets with 50% wheat in all the above index.(2)NSP enzymes supplementation had significant effects on nutrient digestibility and rectal pH and microflora of growing pigs(P0.05).Digestibility of CF,CP,DM and GE for growing pigs increased by 46.19%(P0.05),10.88%(P0.05),11.68%(P0.05),5.18%(P0.05) and rectal Bifidobacterium and Lactobacilluys numbers increased by 43.02%(P0.05),33.80%(P0.05),but rectal E.coli and Salmonella numbers were 52.14%(P0.05),62.11%(P0.05) lower in diets with 0.025% NSP enzymes than in diets without NSP enzymes respectively.However,there were no significant differences between the two levels(0.025% and 0.05%)of NSP enzymes in all the above index.Therefore,NSP enzymes supplementation in diet with wheat can increase nutrient digestibility and improve rectal microflora of growing pigs.Based on the above results,it is suggested that the optimum wheat ratio inclusion in swine diet is about 25%,and the optimum enzyme preparation supplementation level is 0.025%.

In this paper, based on the rescaled range analysis, the indices of Kuala Lumpur Stock Exchange (KLSE) are predicted by the popularly used backpropagation neural network. The choice of KLSE is an interesting one, as KLSE is one of the largest stock markets in the emerging economies in terms of capitalization. Using different trading strategies, a significant paper profit can be achieved by purchasing indexed stocks in the respective proportions. The experiment shows that useful predictions can be made without the use of extensive market data or knowledge.


Overall-water splitting on photocatalysts provides a direct-unassisted path in the conversion of solar energy to chemical energy. Optoelectronic properties (absorbing incident light with long excited state lifetimes) and carrier selective contacts (transporting and transferring the desired electronic carrier to the targeted redox active species) are two key parameters that govern photocatalyst behavior. However, the advantageous small geometry of the highest achieving photocatalysts makes measurement of their carrier selective contacts difficult. Additionally, several mechanisms that enable high energy-conversion efficiencies and large gradients in free energy manifest only at the nanoscale at individual nanoparticle sites. SrTiO3 has been extensively studied and shown to split water with high quantum yields when decorated with HER and OER catalysts. SrTiO3 is used, in this work, as a model system to study mechanisms for charge selectivity on overall-water splitting photocatalyst particles.
 Here, we use three sample geometries to measure local, facet, and catalyst-dependent, electrochemical driving forces and their synergistic enhancement of carrier selectivity, (single crystal planar (b), single crystal co-facet exposed planar (a), facetted nanoparticles (c) loaded with OER and HER catalysts [{Pt/CrO3, Rh/CrO3} and CoOOH respectively]). We use ex-situ conductive atomic force microscopy to individually interrogate the electrical properties of nano-scale catalyst/semiconductor junctions decorated on facet-engineered surfaces of SrTiO3. Supporting experiments of SECM and Operando AP-XPS will be used to measure the charge carrier selectivity when an electrolyte is present and connect the ex-situ characterization observations to operando conditions. In summary, these findings demonstrate the underlying mechanisms and the degree that they play, enabling directed research of photocatalyst systems under the two dominant engineering conditions, high optoelectronic properties and charge selective contacts.

The nitrogen and phosphorus loss of soil is of an important issue for polluting ecological environment and troubling the production and development of agriculture.The paper calculates the quantities of soil erosion and nitrogen and phosphorus loss in four stages during 1952 to 2010 by using RUSLE model based on the characteristics of soil and the ways of land use of Zhanghe Irrigation Area in Hubei Province.The outcomes show that: a) the soil erosion increases from 1 026 375 t/a of the first stage to 1 978 054 t/a of the fourth stage after irrigation and;b) the modulus of nitrogen and phosphorus loss increase from 9.53 kg/(hm2·a) and 11.91 kg/(hm2·a) to 13.03 kg/(hm2·a) and 16.29 kg/(hm2·a) respectively,showing the tendency of gradual increase.It shows the variation of land use of the irrigation area has a certain influence to soil loss and nitrogen and phosphorus loss.Strengthening the management of land use and fertilizer application of the irrigation area has an important significance for lightening soil erosion and reducing non-point source pollution of agriculture.


The pollution of water sources with toxic metal ions is a thoughtful subject. Numerous aquatic systems are polluted with dissimilar toxicmetal ions from various industrial effluents and anthropogenic activities. Water treatment seems to the chief environmental test. The sorption is the best effective method for metal ions elimination in water. Currently, graphene and its composite materials are attaining significance as new generation nano-sorbents. Graphene is a two dimensional nanomaterial with single layer of graphite. These have achieved a great reputation inwater treatment because of their distinctive physico-chemical features. The present chapter describes the elimination of metal ions using graphene and its composite materials. The emphasis has been made on syntheses, applications, regeneration and recycling and future perspectives. Definitely, this chapter will be valuable tool for researchers, government authorities and academicians.


— Crack growth and closure behaviour of surface cracks in 7075-T6 aluminium alloy are investigated under axial loading, noting the difference in fatigue growth behaviour at the maximum crack depth point and at the surface intersection point and also with through-thickness crack growth behaviour. The plane strain closure response at the point of maximum depth of a surface crack is monitored using an extensometer spanning the surface crack at the midpoint of its length. The plane stress closure at the surface intersection point is observed by multiple strain gauges placed at appropriate intervals ahead of the crack tip and continuously monitored without interrupting the fatigue test. The crack opening ratio is found to be about 10% greater at the maximum depth point than at the surface intersection point. Under axial loading, the difference in plane strain crack closure behaviour between the surface crack and the through-thickness crack is relatively small. Growth rates of surface cracks can be well described by the effective stress intensity factor range based on the closure measurements made in this study. The growth rates in terms of the effective stress intensity factor range seem to be slightly slower in surface cracks than in through-thickness cracks.


To the high gas-liquid ratio gas well,results of wellbore temperature distribution and bottom hole flow pressure from some methods are with low accuracy,and some methods with high accuracy could not be used conveniently.In order to solve such problems,flow characteristics and heat transfer of continuous steady production were analyzed based on heat transfer,thermodynamics and multiphase flow theory,and a computing module for bottom-hole flow pressure calculation of high gas-liquid ratio gas well was established where Beggs-Brill formula,Kelessidis-Dukler flow pattern discriminance and a temperature distribution computing method are included.The method had been applied to a gas well in Xinjiang.Comparing to test data,results of temperature distribution and bottom hole flow pressure from this theoretical model have good accuracy and the averaged error is only 3%.In the meanwhile,parameters needed for calculation can be obtained easily.


Nanolaminates of polycrystalline (tetragonal+orthorhombic) HfO2 and amorphous Al2O3 are sputter deposited on unheated fused SiO2, air annealed at 573–1273K, and analyzed by x-ray diffraction and spectrophometry. Significant O 2p→Hf 5d interband absorption occurs in all films at energy E⩾6.2eV. For E<6.2eV, films annealed below 1273K retain a featureless optical absorption edge despite further crystallization. A band with a 5.65eV onset concurrently develops with m-HfO2 crystallization after a 1273K anneal, indicating this phase and not nanocrystallinity per se is responsible for increased absorption.


In order to explore the transient characteristics of the large-scale vertical siphon axial flow pumping station during the start-up and exhaust process, numerical simulations were carried out on the start-up process of the axial flow pumping station under the two starting modes of pre-opening the vacuum breaking valve and keeping the vacuum breaking valve closed. The calculation results show that during the start-up phase of the unit, the flow separation phenomenon of the impeller channel of the pump device with the vacuum breaking valve closed is serious, the large-scale vortex in the guide vane blocks the flow channel, and the instantaneous impact on the blade surface is strong. The flow field of the pump device with pre-open vacuum failure valve is obviously less affected by the instantaneous impact characteristics during the start-up of the pump. The range of high entropy production area in the impeller channel is reduced, the duration of high entropy production area is significantly shortened, and the instantaneous impact on the blade surface is weak. Under the two starting modes, the internal flow field of the pump device is similar in the evolutionary law. The unstable flow phenomenon of the pump device is most prominent in the weir flow stage. The maximum instantaneous impact on the blade surface also mainly occurs in the weir flow stage. A very small part of the remaining gas in the siphon formation stage is difficult to discharge and takes a long time. After the pump device is exhausted and enters a stable operation state, the external characteristic parameters are in good agreement with the test results. Compared with the starting method in which the vacuum breaking valve is kept closed, the method of pre-opening the vacuum breaking valve reduces the maximum starting head by 20% and the exhaust time by 43%. The pre-open vacuum breaking valve effectively avoids the system instability caused by the start-up and exhaust of the pump device.


This essay offers an analysis of Barack Obama's official announcement speech of 2007 and his definition of "change." Contrary to critics who have separated "vernacular" and "elite" strands of republican philosophy, I argue that Obama's "change" rhetorically combined these frameworks into a threefold appeal for political leadership: the expansion of collective freedom, the necessary participation of citizens in public affairs, and the centrality of speechifying to political leadership. Understanding this characterization of change allows better comprehension of Obama's transition from politician to presidential candidate within his situational constraints, as well as the distinctive public memory attributed to Abraham Lincoln throughout the announcement speech.


The aim of this study is to present, analyze and assess the level and relations of labor costs and productivity in the OECD countries. The analyses of labor markets in European Union states or in the OECD countries show that these markets are characterized by very similar measures regarding the levels of professional activity, unemployment rate and efficiency of labor market policy programs. However, the difference in the level of wages still remains high. Among the reasons for this phenomenon we can indicate the levels of labor costs and productivity, which determine the levels of wages in particular member states. The thesis stated in the study is that the maintained differences in wages in the OECD countries may be explained by differences in the levels and relations of labor costs and productivity, which are discussed in detail in the study. In the first and in the second part of the elaboration the analysis of productivity was carried out including definition of this subject and special empirical data showing measurement of productivity. In the third part we presented labor costs and tax wedge in the same period of time. The hierarchical clustering algorithm allowed to distinguish many groups of countries with different degree of similarity in terms of compared variables. Finally, the fourth part is devoted to a statistical analysis using measures such as the correlation coefficient between presented variables. The period of analysis are years 2000-2014 and the main source of data is the OECD database available in the Internet.


Objective: To investigate the effects of Xingding Ginkgo- Dipyridamolum Injection on the treatment of retinal artery occlusion. Methods: 58 eyes of 58 patients diagnosed as retinal artery occlusion were included in this study. 18 eyes of 18 patients were branch retinal artery occlusion( BRAO),among which there were 2 patients complicated branch retinal vein occlusion( BRAOBRVO) and 2 patients complicated central retinal vein occlusion( BRAOCRVO). 40 eyes of 40 patients were central retinal artery occlusion( CRAO),among which there were 7 patients complicated central retinal vein occlusion( CRAOCRVO). The patients( 32 males and 26 females) aged from 36 to 86 years old with the average age of( 62. 12 ± 13. 79). The course of disease was ranging from 4 hours to 20 days with the average of( 5. 13 ± 5. 05) days.The visual acuity was ranging from light perception( LP) to 1. 0 with the average of( 0. 17 ± 0. 30). All patients were given20 mL Xingding Ginkgo- Dipyridamolum with 250 mL 5 % Dextrose Injection( or 0. 9% Sodium Chloride Injection) intravenous infusion once a day for 3 days to 6 weeks,with a average of( 2. 24 ± 1. 18) weeks,combined with sublingual nitroglycerin,aspirin,methycobal and ocular massage. The visual acuity,colour funds photography,optical coherence tomography( OCT) and fundus fluorescein angiography( FFA) were performed during the follow up within 1 to 6 weeks. Results: In most cases,the retinal opacification faded and cherry- red spot gradually disappeared during their follow- up,except two cases got worse. The mean BCVA was significantly improved at 1 week,2 and 3 weeks after treatment. The mean central macular thickness decreased at 2,3 weeks after treatment and statistical difference was found compared with pretreatmentduring the follow- up period( P 0. 05). 17 cases received FFA evaluation after treatment,10 at 1 week,6 at 2 weeks,1at 3 weeks post- treatment,16 of 17 cases showed shorter A- RCT and improved retinal circulation,only 1 case showed no difference. Conclusions: Xingding Ginkgo- dipyridamolum Injection works as vasodilator,which can increase retinal blood supply and visual function,and is likely to be beneficial for the treatment of retinal artery occlusion. Besides,no significant ocular and systemic adverse reactions were found during 6 weeks follow- up me.


Postnatal hamsters were examined for a metabolic response to cold by measuring oxygen consumption at ambient temperatures of 25°, 30°, 33°, and 36°C. In conjunction with this, colonic temperatures were recorded, and the animals were examined for brown adipose tissue development.

During the first ten days of postnatal development hamsters increased their O2 consumption linearly as ambient temperature was raised from 25° to 36°C. Thus, they are initially poikilothermic. Body temperatures were directly dependent on environmental temperature, and no mature brown fat deposits had yet developed.

On days 11 and 12, O2 consumption curves began to vary from a linear relation with ambient temperature, and small inflexions developed at 30° and 33°C. By postnatal days 14 and 15 maximal values were recorded at 25°C. Simultaneously, brown fat deposits developed definitive characteristics and body temperatures came to range only slightly below adult temperatures during exposure at 25°C.

During the latter stage of maturation studied in these experiments, days 17 to 21, the animals achieved homeothermic stability between 25° and 36°C. Only 25°C prompted a metabolic increase, 30° to 36°C became a zone of thermal neutrality, and body temperatures came to equal or exceed adult temperatures. The animals had gained significant weight, thereby increasing thermal insulation, and brown fat deposits had accumulated additional lipid.


Air quality monitoring data and related meteorological data from October of 2005 to October of 2006 are collected to find out the relation between air quality and the northern industrial area in Nanjing.


Three field studies were carried out on a silty clay soil - Haplaquoll (Molic Gleysol), during the 1996/99 season, at Epagri/Itajai Experimental Station in southern Brazil, 260 56' 35s S and 480 45' 37s W, to evaluate clomazone persistence in soil and water. Clomazone 500 EC (1996/97) and 360 CS (1997/98 and 1998/99) was applied in the water in post emergence of pre-germinated seed in flooded rice area. Herbicide concentration in the soil and water was quantified before and after spraying, through several samples of water and soil taken up to rice harvesting time and analyzed with gas chromatography. In the first year, clomazone formulation 500 CE was not detected either in soil or water after 8 and 32 days after application (DAA), respectively. In 1996/97, about 3% of the amount applied remained in the paddy water by 16 DAA. In the following years, clomazone residue was detected in water up to 24 DAA. Clomazone residue levels in soil were below detectable levels after 4 and 16 DAA, in 1997/98 and 98/99, respectively. The results show that after applying clomazone (formulations EC and CS) in the water, growers should hold the water in the fields during 3 to 4 weeks, without any outflow of the pesticide treated water to waterways, otherwise superficial water could be contaminated.

The traditional definition involves two key elements of topological structure: type of kinematic pairs and connection relations among links. But these two key elements are not enough to exactly describe topological structure of a mechanism. For the two mechanisms in Fig. 2.4, they have the same description if only these two key elements are used. But actually they have different topological structures.


In this article) I do not propose to trace out once again the history and development of that type of play, since labelled "sentimental comedy", which flourished at the beginning of the eighteenth Century, receded before the onslaught of Goldsmith and Sheridan, revived once more at the end of the Century in the plays of Mrs. Inchbald and Richard Cumberland, and finally died, to all appearances, in the first two decades of the next Century. That has already been done by far abier writers than myself, and can be read in their works. Professor E. Bernbaum's Drama of Sensibility still remains a classic; in more recent years Professor Allardyce Nicoll has written the history of sentimental comedy in bis three volumes Restoration Drama, Early Eighteenth Century Drama, and Late Eighteenth Century Drama, while Mr. F. W. Bateson has made a study of some of its manifestations during the Augustan Age in bis English Comic Drama, 1700—1750 (1929). All these are excellent pieces of work, but they leave several important questions undecided. When, and how did this sentimental comedy come into being? Why did it gain preeminence and popularity at the time that it did? What became of it upon its so-styled decay? What is its significance with regard to present-day drama? No writer, so far äs I am aware, has traced it any farther back than the last few years of the Restoration period, yet no-one will contend that any species of play can arise, mushroom fashion, instantaneously, and independent of the drama that has preceded it. The English drama, in spite of the Civil War, has shown one continuous stream of development, and if therefore we can find no trace of sentimental comedy in the Restoration, then the type of play to which we have given that name must have evolved


Aims. The launch of Swift has allowed many more novae to be observed regularly over the X-ray band. Such X-ray observations of novae can reveal ejecta shocks and the nuclear burning white dwarf, allowing estimates to be made of the ejecta velocity. Methods. We analyse XMM-Newton and Swift X-ray and UV observations of the nova V598 Pup, which was initially discovered in the XMM-Newton slew survey. These data were obtained between 147 and 255 days after the nova outburst, and are compared with the earlier, brighter slew detection. Results. The X-ray spectrum consists of a super-soft source, with the soft emission becoming hotter and much fainter between days ∼147 and ∼172 after the outburst, and a more slowly declining optically thin component, formed by shocks with kT ∼ 200–800 eV (corresponding to velocities of 400–800 km s −1 ). The main super-soft phase had a duration of less than 130 days. The Reflection Grating Spectrometer data show evidence of emission lines consistent with optically thin emission of kT ∼ 100 eV and place a limit on the density of the surrounding medium of log (ne/cm −3 ) < 10.4 at the 90% level. The UV emission is variable over short timescales and fades by at least one magnitude (at λ ∼ 2246–2600 A) between days 169 and 255.


Confluence is a critical property of computational systems which is related with determinism and non ambiguity and thus with other relevant computational attributes of functional specifications and rewriting system as termination and completion. Several criteria have been explored that guarantee confluence and their formalisations provide further interesting information. This work discusses topics and presents personal positions and views related with the formalisation of confluence properties in the Prototype Verification System PVS developed at our research group.


Five methods of aggregated indices,and Iwao's way(regressive relation by M-M) and power law of Taylor were used to test the spatial distribution pattern of Bemisia tabaci(Gennadius) adults in Gerbera jamesonii Bolus field.The results showed that the adults of Bemisia tabaci(Gennadius) belonged to the spatial pattern of aggregative distribution.The cause of their aggregation was tested by Blackith's method.When M2.0995,their aggregation were resulted from some environmental factors such as climate,soil humidity,plant growth and so on;when M≥2.0995,their aggregation were resulted from their mass conduct.Based on this distribution pattern,a optimum theoretical sampling model[N=t2/D2(1.1716/M+0.1377)] and a optimum sequential sampling model [T0(N)=3N±4.2728N] were proposed.


We present a practical and inexpensive method to recon struct 3D scenes that include piece-wise planar transparent objects. Our work is motivated by the need for automat ically generating 3D models of interior scenes, in which glass structures are common. These large structures are often invisible to cameras or even our human visual system. Existing 3D reconstruction methods for transparent objects are usually not applicable in such a room-size reconstruc tion setting. Our approach augments a regular depth cam era (e.g., the Microsoft Kinect camera) with a single ultra sonic sensor, which is able to measure distance to any ob jects, including transparent surfaces. We present a novel sensor fusion algorithm that first segments the depth map into different categories such as opaque/transpare nt/infinity


Human resource risk is the probability of unfavorable events' and threats' realization occurrences coming from people as a result of decision making. It plays an increasing role in the companies' activities. Threats of this type are of complex nature and are also called anthropogenic. Risk realization leads to the loss of important confidential information, commercial losses, profits' losses, and a decline in the company's goodwill. Adequate reduction of personnel risks will improve the personnel quality and, consequently, reduce the damage from the risk threats' realization.


The establishment of the new Bachelor of Engineering Technology qualification has brought many challenges for curriculum developers. In particular, the challenges pertaining to assessment of the newly developed graduate attributes require careful consideration, as the approach should be in line with what is envisaged by the Engineering Council of South Africa's standard. In this work, we analyse some of the implications of the new qualification standard on the shift in approach to assessing graduate attributes. We propose a model for assessing the graduate attributes and collection of evidence of compliance. The findings of implementation of this model for assessment of one of the graduate attributes are given. We also relate some experience with the adoption of this assessment approach.


anti-hypertensives, the same was on a nicardipine infusion, and dose steroids. Further inquiry with family unveiled a history of panic attacks, headaches, and palpitations for years, often leading to emergency room visits. Labs confirmed a high suspicion of pheochromocytoma with elevated plasma and urine normetanephrines and metanephrines. A CT scan of the abdomen showed a left adrenal mass. Phenoxybenzamine was started. She was decannulated from ECMO 72 hours later due to improved respiratory stability and cardiac function. Repeat ECHO showed an improved EF of 55%. An adrenalectomy was per- formed on hospital day 24 once hypertension and tachycardia was well controlled on the floor. Pathology confirmed pheochromocytoma. She was placed in the surgical ICU for blood pressure and glucose control after surgery. She was on carvedilol at discharge and insulin was discontinued. Results: ECMO proved to be a life-saving measure allowing time to uncover this patient's undiagnosed pathology. Manage- ment of catecholamine surges while on ECMO was a challenge, often requiring quick on-site decisions. Multiple critical care specialist were crucial for this patient to survive with no lifelong sequelae. known aortic root dila-tion of 35mm. During the initial assessment, the patient was alert, oriented and hemodynamically stable. An abdominal ultrasound revealed an aortic aneurysm. CT confirmed a 58mm by 73mm ruptured abdominal aortic aneurysm with organ and bowel displacement secondary to a large hematoma. During the CT scan he developed hypotension and altered mental status. He was intubated and fluid resuscitated. He underwent emergent repair of the aneurysm with a 14mm Dacron tube graft. Given his abdominal distention from the hematoma, he was unable to undergo primary closure until post-op day 7. He was discharged on post-op day 13. Results: There are currently no recommendations for evaluation and monitoring of the abdominal aorta in patients with MFS. The American Heart Association rec-ommends an echo at the diagnosis of MFS and six months later to evaluate aortic root diameter. If the diameter remains stable, it is recommended to repeat an echo annually. Additionally, a CT or MRI should be performed at diagnosis and repeated every 3–5 years. To the best of our knowledge, this is the first reported case of a ruptured abdominal aortic aneurysm in a child with MFS. For patients with MFS and abdominal pain, it is paramount to have a high index of suspicion for abdominal aortic abnormalities. We believe this case provides the basis for a discussion regard-ing the need to develop screening protocols for abdominal aortic pathology once a patient with MFS develops aortic root dilation. proposed and micro-vascular Diagnosis is established by characteristic echocardiogra-phy (ECHO) findings. Methods: A 73-year-old hemodynamically stable male patient presented in rapid atrial fibrillation (heart rate 156 beats-per-min). Past medical history included hypertension, diabetes mellitus, stage 3 chronic kidney disease and giant cell arteritis. ECHO demonstrated normal LV ejection fraction (LVEF) of 58% and moderately dilated left atrium. Rate control was achieved with diltiazem drip and then oral Sotalol. The patient was on intravenous Hepa-rin. Direct current (DC) was delivered for cardioversion (CV) to sinus rhythm. Within 24 hours, the patient developed shock and acute pulmonary edema and was required transfer to Intensive care unit (ICU). This was followed by Pulseless electrical activity (PEA) arrest requiring intubation and mechanical ventilation. Urgent ECHO revealed severe mid-anterior, anteroseptal and apical hypokinesis. Basal segments contracted normally and LVEF was 30% - findings characteristic of TCM. He required norepinephrine for hemodynamic support (Milrinone not well tolerated). After a week of ICU support, ECHO revealed complete recovery of LVEF (60%). The patient was successfully weaned off Norepinephrine, extu-bated and discharged to rehab. Results: We present the first male patient with CV related TCM causing acute LV failure and cardiogenic shock (with classic ECHO findings). Coronary angiogram was not performed due to acute kidney injury. TCM after DC cardioversion is a rare but serious complication. The pathophysiology remains unknown. Possible hypotheses are transient cardiac dysfunction and idiosyncratic myocardial damage from DC shock. Prognosis is generally good with supportive treatment. Further research is required to explore the underlying mechanisms.
