Many community college honors programs have seen steep budget cuts in recent years, affecting the number of honors students that can be served at the 1,200 community colleges in the United States. Many excellent, longstanding honors programs at community colleges have recently struggled with enrollment and resources. NCHC-member colleges have often described their challenges in filling honors classes and their ongoing struggles with resourcing honors programming. Especially at the community-college level, honors programs in the United States are often being asked to do more with less. These developments are certainly true in Spokane, Washington, where, prior to working with American Honors, our community colleges had struggled for many years to provide substantial honors offerings. In 2011, Spokane had approximately 16,000 full-time equivalent students enrolled in its two accredited community colleges, but fewer than twenty students per year enrolled in honors courses, which have existed in some form for over twenty years. At Spokane Falls Community College (SFCC), one of the colleges in the Spokane District, an average of twelve students per year enrolled in a section of an honors anthropology seminar. No other honors courses were offered. After a long planning process undertaken by faculty and a subsequent task force, SFCC offered four honors seminars in 2011-12, enrolling an average of only 7.5 students per section. Given recent state budget cuts, these class sizes were fiscally unsustainable, even in only standalone honors courses rather than a full-scale program. With only a handful of sections offered, the administrative and clerical oversight necessary for large-scale growth was not feasible. Honors-specific student services, including extensive transfer coaching and a full menu of coursework, were also not practical. As a result of our public-private partnership, however, CCS has been able to dedicate additional staff time and the resources of American Honors to plan and recruit for the honors program. Previous CCS honors efforts did not include a large-scale recruiting effort, which has been one of the most immediate and tangible benefits of the partnership. Since working with American Honors, Spokane's honors programming has grown tremendously, expanding our ability to serve more honors-caliber students and to serve them better. After a pilot program in 2012-13, the current academic year saw 147 honors students enrolled at Spokane's two community colleges. Over 700 applied for seats in this competitive program, suggesting that far more honors students than had been drawn to our honors offerings. Retention has been high so far: 92% of the fall 2013 students progressed into winter 2014. Their average GPA at admission was 3.6. Average SAT scores, too, were higher than among most college students: 542 (reading), 554 (math), and 529 (writing) . SAT data are only available for 60% of incoming Spokane honors students, suggesting that many did not initially see themselves as headed to four-year colleges and universities.) The high number of applications, despite the higher cost of participating in honors, suggests that many high-caliber students may consider community college honors options if they are available. The cost of full-time enrollment in American Honors at CCS is $6,700, including fees, which is approximately 40% higher than regular CCS tuition but is still lower than the cost of the closest and most affordable four-year public institution in our state. Data indicate that the AH student services model has helped Spokane's students succeed. From the day students enroll, they are paired with an honors mentor, provided by American Honors, who remains their single point of contact throughout their duration in the program. The honors mentors are hired by American Honors, but the Spokane team participates in interviews and provides input into staff selection. …


As a number system, the magic square is different from the others. Characteristic depends not only on size but also depends on numerical character in computation. This paper has redefined the term of magic square formally, by exposing the inductive general characteristics of cases to numerical ordering of numbers.

Under the tendency of integrating dispatching with control in recent years the access control of electric power SCADA system becomes more and more complicated, for this reason, the defects in traditional discretionary access control, mandatory access control and role based access control(RBAC) are analyzed, and based on existing SCADA system and traditional RBAC a multi-area access control model, in which the concept of the area of responsibility(AOR) is led in, is proposed, and the permission is split into the regional access permission and public service access permission to make the permissions enable shunted according to AOR, and based on dispatchers' requirements on production and management different dispatch responsibility range are divided to allocate different permissions in different AORs. Thus the demand of modern SCADA system on conducting differentiated management of permissions according to areas to effectively prevent the trans-domination area maloperation. The validity and reliability of the proposed model are verified by results of applying it in actual project.


Background: The efficacy of statin therapy in preventing both primary and secondary coronary heart diseases in young and middle aged people is well known and well supported by numbers of landmark clinical trials. Literatures addressing reduction of cholesterol level in elderly (septogenarians & octogenarians) as primary prevention strategy for coronary heart diseases are scarce. The elderly population rarely suffer from primary heart attack and as such routine prescribing of statin to treat dyslipidaemia as primary prevention of coronary heart disease is controversial, particularly when there are reports that statin therapy in elderly population causes cancer, haemorrhagic stroke, dementia and so on. The present study was aimed at answering these questions in order to help formulating a separate guideline for statin therapy in elderly. Methods: The present study reviewed literatures of recent and recent past origin. A systematic literature search of MEDLINE, EMBASE, CINAHL, Web of Science, CANCERLIT and the Cochrane Systematic Review Database have been used to identify randomized clinical trials of statin use with the main focus on primary or secondary end point of CHD, acute coronary syndrome (ACS), cardiac death, overall death, stroke and cancer diagnosis or cancer death. To be included in this review, (1) the entire study subjects or a sub-group were of age 55 years or more (2) had a mean (or median) duration of patient follow-up of at least 1 year, (3) enrolled a minimum of 100 patients, and (4) reported data on the incidence of either cancer diagnosis or cancer death in the elderly population. Conclusions: The study concludes that statin therapy in elderly people may not provide additional benefit in the prevention of primary cardiovascular diseases or death due to primary cardiovascular events. Though most of the studies ruled out excess risk of cancer or other noncardiovascular events, their probability cannot be entirely ignored. However, there is report that addition of statin to the existing drug schedule of elderly subjects does not cause drug interaction. Large-scale, randomized trial on truly representative population with long term follow up will provide authentic data to answer the question whether statin therapy in elderly people with dyslipidaemia can prevent primary heart diseases. Key words: Statin; primary prevention; coronary heart disease; dyslipidemia; elderly people. Ibrahim Card Med J 2011; 1(1):45-55


A display device, a driving method, and a computer program for the display device prevent burn-in by controlling a signal level of an image signal. A mean calculator inputs an image signal having a linear characteristic and calculates the means per pixel of the signal level of the image signal having the linear characteristic. A mean memory(150) successively memorizes the mean calculated by the mean calculator. A still image decision device(122) determines whether the image displayed on the current screen is the still image or not based on differential value between the mean of the mean memorized in the mean memory unit and the previously mean. If the still image decision device determines that the image displayed on the current screen is the still image, a coefficient calculator(164) calculates the coefficient for reducing the brightness of a picture displayed on the display unit. A coefficient multiplier multiplies the coefficient calculated by the coefficient calculator by the image signal.


Pasta are important foods in Europe, mainly in ltaly (25 kg/capita/year), Greece, France (6 kg) and Spain . The best products (nutritional value, cooking quality, aspect) are processed from durum wheat semolina . Because of this difference in quality, and because of the new market regulation on January 1993, that will include a free circulation between the member States of pastas made of durum wheat / common wheat mixtures, the consumers will have to know through an efficient and verifiable labelling the exact composition of the pastas that are marketed.


Zmiennośc cech tekstualnych i strukturalnych w piaskowcach turbidytowych: piaskowce cergowskie (oligocen, Karpaty Zewnetrzne)

Trends of variation determined quantitatively for bed thickness, stratification structures, grain size, and qualitatively for miscellaneous sedimentary structures, are discussed in relation to lithosome shape and inferred basin geometry. Besides downcurrent gradients of textural and structural features, there exist gradients across paleocurrent direction. In the elongated lithosome of the Cergowa sandstone marginal near-source and axial far-downcurrent zones have the same textural and structural characters.


Abstract : Open fractures require irrigation and debridement to prevent potential infection. Irrigation and debridement, however, removes the body's first healing response, such as fracture hematoma. We implemented an irrigated radius defect model intended to represent the open fracture setting with bone loss. We evaluated feasibility to investigate the role of platelet rich plasma (PRP) to restore healing response. We completed the hypothesis development protocol evaluating the separate and combined roles of irrigation and PRP augmentation in a rabbit radius defect model. Irrigation was with commercially available pulse lavage. PRP was manually prepared with centrifugation and separation. Platelet concentration was compared to whole blood platelet concentration. PRP was combined with thrombin prior to insertion in the defect. Healing was assessed radiographically, histologically and with microCT. Intended power was not achieved due to animal loss (ulnar fracture and due to unrelated intestinal causes). Platelet concentration exhibited variability across all rabbits, from 2x to 8x. Histologic scoring and radiographic evaluation did not confirm that irrigation reduced healing potential, at 3 and 6 weeks, but sample number was compromised and results were not definitive. Future work will evaluate one time point, fibrinogen will be used to avoid quick activation of thrombin, and the ulnar defect will be considered to avoid inadvertent forearm fracture.


It is necessary to identify immunologic parameters in children with latent tuberculosis infection. Immunological profile in children with v arious manifestations of tuberculosis infection isdescribedin literature not sufficiently that requires further investigation. The article presents results of the survey of 155 children aged 3 to 14 years with various manifestations of tuberculosis ( TB) and positive results ofDiaskintest® (DST) and QuantiFERON-TV Gold (QFT). Diagnostic complex included the data of clinical, radiological (multis lice computed tomography) and immunological examination methods. All children were assigned to two groups: I group - 126 patients with tuberculosis disease (TB) , II group - 29 patients with latent tuberculosis infection (LTBI). Based on results of the research it was found out a number of peculiaritiesof immune response in childr en with latent TB infection and active TB disease of the respiratory organs. In LTB I marked trend of elevation in induced production of cytokines (IL-2, IL-4, IFN-g) and changes of some indicators of phagocytic activity of neutrophils (FC and PHI) were revealed. While in development of TB activation of the humoral response was a prevailing feature(increased titers of PTOT in the complex ser ological reactions and level TB antibodies of Ig A and Gclassesbyanda-tb ELISA). This data can serve as additional diagnostic criterion for the diagnosis of LTBI in c hildren.


The wear resistance and wear mechanism of three types of ceramic microbeads, mullite composite (22.6% zirconium sili- cate, 75% mullite, 2.4% calcium carbonate, in mass), zirconium silicate and alumina, were studied by a wear test under both dry and water lubrication conditions. The results show that the wear extent of the ceramics increases with the increase of the applied load. For water lubrication conditions compared with dry friction under same load, the wear of the mullite composite and zirconium silicate is mitigated but that of alumina increases. The main wear mechanism of the ceramics is plastic deformation and microcracks at lower loads, and brittlement stripping and grains pulling out at higher loads.


Exosomes are small vesicles originating from late endosomes, 30–100 nm in diameter with typical cup‐shape morphology. They are reported to bear high levels of a narrow spectrum of molecules involved in immune response and signal transduction. Apart from removing obsolete membrane proteins, some surprising biological functions of exosomes were unveiled recently and their applications in immunotherapy of tumors are currently intensively investigated. Dendritic cell‐ (DC) and tumor‐derived exosomes have considerable anti‐tumor effects in experimental studies and several clinical trials. Despite their potential applications in eliciting a "positive" immune response, exosomes might induce some "unwanted" immune responses, such as immune tolerance and immune evasion. Therefore further investigations about the physiological functions of exosomes and the optimal way of exosome application in tumor immunotherapy are necessary. This review presents recent developments in the field of exosome research and focuses on its applications to tumor immunotherapy.


Abstract : In 1971, a long-term, deep-ocean test was started on eighteen concrete spheres, 66 inches (1, 676 mm) in outside diameter by 4,12 inches (105 mm) in wall thickness. The spheres were placed in the ocean at depths from 1,840 to 5,075 feet (560 to 1,547 m). Over a 6.4-year period, yearly inspections of the spheres by submersibles have provided data on time-depedent failure and permeability. After 5.3 years, three of the spheres were retrieved from the ocean for laboratory testing. Data on concrete compressive strength gain, short-term implosion strength of the three retrieved spheres, and permeability and durability of the concrete were obtained. This report summarizes the findings from the laboratory and ocean tests. (Author)


Person re-identification is an important task in the field of video surveillance that concentrates on identifying the same person across different cameras. Some methods cannot learn effective image representations, due to the low resolution of pedestrian image data sets. In this article, we propose a novel Siamese network architecture with layers specially designed to address the problem of re-identification. The architecture proposed in this work is applied to the edge of the cloud infrastructure, which can accelerate the speed of pedestrian retrieval. Our network outputs a similarity value when a pair of images is given as input, indicating whether the two input images show the same person. Novel elements of our architecture include a residual model layer that includes an "identity block" and a "conv" block, which considerably capture more efficient features between the two input images. A global average pooling layer is adopted to reduce the model complexity before a fully connected layer, which minimizes person retrieval time in edge computing. Our proposed method significantly improves previous on: CUHK03 by 30% in rank-1, Market-1501 by 35% in rank-1. We also demonstrate that the proposed method outperforms most state-of-the-art methods on the two public benchmarks.


Cytokines belonging to the TGF-beta family ubiquitously participate in several cellular processes and elicit cell-context specific responses in various cell types. In recent years, attention has been drawn to understand the TGF-beta1-dependent signalling cascades which alter the differentiation state of epithelial cells, especially the de-differentiation of an epithelial cell into a mesenchymal-like cell type, also referred to as EMT (epithelial-mesenchymal transition). EMT-processes, characterized by the loss of E-cadherin expression, loss of cell-cell adhesion, and an enhanced cellular mobility have originally been described as developmental processes, essential for gastrulation and mesoderm development as well as the formation of migratory neural crest cells. Nowadays, regardless of the original description known from developmental biology, the term 'EMT' is used to describe several changes of epithelial cells into fibroblastoid-like cells. Partially, this is due to the use of equivocal markers that aim to define an EMT-process. Under pathological conditions, EMT-like processes have been proposed to result in organ fibrosis and to participate in cancer progression, though this is still a matter of intense scientific debate. Nevertheless, in-vitro as well as in-vivo studies of cytokine induced EMT-associated processes have critically contributed to the identification and characterization of factors that regulate cell plasticity and to a better understanding of the complex cytokine-induced changes in epithelial differentiation. In this work, using high-throughput microarray techniques, the Forkhead factor FoxQ1 was identified as transcriptionally induced in a TGF-beta1-responsive cell culture model of cytokine-induced EMT-like progression, suggesting a potential impact of FoxQ1 expression in the modulation of epithelial plasticity. Subsequent RNAi-based functional analyses revealed that FoxQ1 influences epithelial plasticity by affecting the arrangement of cytoskeletal proteins, the formation of cell-cell contacts, and junction protein expression (e.g. E-cadherin and Occludin). In addition, FoxQ1 was found to regulate cell proliferation by affecting the expression of Cyclin-dependent kinases and to modify the migratory capacity of epithelial cells. In relation to TGF-beta1 signalling, this work provides evidence that FoxQ1 is induced in a Smad4-independent manner and is a putative downstream target of the transcription factor Zeb1. Transient repression as well as stable overexpression of FoxQ1 remodelled TGF-beta1-dependent alterations of cell morphology and provided evidence that FoxQ1 is a potent mediator of TGF-beta1 signalling. Microarray-based gene expression analyses of TGF-beta1-induced epithelial cells with an impaired FoxQ1 induction indicates that FoxQ1 is a potent mediator of TGF-beta1-dependent gene expression changes, including the differential expression of transcription factors that have previously been linked to the regulation of epithelial plasticity and EMT-like progression.


The role of education in determining the labour force participation of women in Asia is analyzed both theoretically and empirically. A household bargaining model over the labour market participation of the wife is proposed based on the Generalised Nash Bargaining Solution. The effect of education has on the wife's participation in the labour market is shown to depend on the wife's preferences over participation. Household survey data from five Asian countries are used in estimation of a reduced from model of the wife's participation. The effect of education on the wife's participation varies significantly by country with participation less likely in countries with more traditional gender roles.


Sharding technology is a promising solution for improving the scalability of blockchain systems. However, it faces the problem of allocating suitable trusted nodes into separate shards to satisfy security and efficiency requirements. Existing blockchain sharding methods fail to consider shard trust difference, communication latency difference, and node count difference among shards. This tends to increase the risk of a blockchain failure. This work proposes a novel blockchain sharding model for node allocation by considering shard trust difference. Its key idea is to allocate nodes of different trust levels to suitable shards to make shards have almost the same trust, such that shards' reliability increases and blockchain failure probability decreases. To reduce the communication delay among shards, this work considers the communication latency difference and node count difference among shards. It proposes a sharding algorithm to iteratively adjust node allocations such that an optimal or near-optimal node allocation set is obtained. Simulation results show that the proposed method can effectively improve shard security and the performance of blockchain sharding compared with two state-of-the-art methods, i.e., Monoxide and Rapidchain, in terms of throughput, latency, and blockchain failure probability.


This is a well-written paper concerning immersion freezing of water droplets triggered by coal fly ashes (CFA). This is a timely topic which fits very well into ACP. The authors compare samples from different sources concerning their ice nucleation activity. They use different set-ups (LACIS, WISDOM, SPIN, LINA) to do so. They correlate their findings with the physical-chemical properties of the particles. They conclude that CaSO4 and CaO are the crucial mineral components and that thus surface hydration of these fractions can have an important impact on the ice nucleation activity of CFA.

This paper investigates the problem of user‐centric cooperative edge caching in content delivery networks to leverage service provisioning at the network edge and to improve the quality of experience by minimizing the end‐to‐end delay. By taking advantage of the major characteristics in fifth‐generation networks, users can access contents not only from the nearest small base station (SBS) but also from other SBSs in the vicinity that have the requested precached contents. In the proposed scheme, a user‐centric delivery approach is considered in such a way that the base station can respond to the user request as long as it has enough resources. To this end, a caching algorithm is introduced whereby a group of SBSs cooperatively share storage and decide on the caching policy together aiming to cache as much contents as possible under the capacity constraint. Moreover, a modified matching theory is used for content delivery taking the bandwidth requirements into account. Simulation results show that the proposed scheme can achieve 99.5% local serve ratio when the SBS has a caching capacity of 40% the overall file size, and 20 available communication channels for content distribution.


form, the problem posed is that of monitoring a function that society trusts government to carry out itself32 when government has delegated that function to an entity that society does not trust. The obvious response, and the one that now prevails in the realm of prison privatization," is to make government the monitor. Surely the state can be trusted to monitor an activity that it is trusted to perform. Several factors suggest, however, that the state as monitor will be less reliable than the state as administrator." ' First, the costs of administrative review 5 will appear in the budget of the government that let the prison contract, perhaps with much fanfare, for the express purpose of saving corrections dollars. That entity will not allow the sum of the contract price and the cost of monitoring to exceed the costs it incurred itself in running the prison system. Monitoring expenditures are thus capped by a criterion wholly unrelated to prison quality. 6 The monitoring agency will have a similar reason not to monitor the firm too closely; the agency, or one closely allied with it, selected the firm and will be tarred with the same brush if improprieties are discovered. 37 If no ready competitive market exists to which the state can turn for another operator, the monitoring agency may recognize that the state has state, to some salaried employee. On this view, the state is simply a legal fiction, "a nexus for a set of contracting relationships among individuals." Jensen & Meckling, supra note 19, at 310 (emphasis omitted). We accept without qualm the state's prerogative so to delegate, both as a practical matter and because the constraint on the distribution of profits by the state, see supra note 25, perhaps combined with a perceived commitment to public service, see supra note 24, and a sense of greater political accountability, reassures us that the institutional arrangement is sufficient to monitor and to check the tendency of state employees to self-enrichment, and to guarantee their fidelity to societal preferences. When the organizational form changes from state hiring of private individuals to state hiring of a private firm, the problem remains the same: how to ensure that public duties are not sacrificed to private interest. Different monitoring mechanisms may be employed, but if they are as successful as those deemed acceptable under state management, the objection that the state has no authority to delegate cannot seriously be raised. 32. The trust may not be wholehearted, but it is sufficient to allow prison operation. 33. N.Y. Times, Feb. 11, 1985, at B6, ol. 3 (facilities inspected and monitored by state). 34. It remains to be demonstrated that another monitor can perform more ably. Cf Coase, The Regulated Industries-Discussion, 54 AM. ECON. REv. (Papers and Proceedings) 194, 195 (1964) (relevant comparison is "between social arrangements which are all more or less failures"). 35. Such costs are not inconsiderable. In the wake of Ruiz v. Estelle, 679 F.2d 1115 (5th Cir. 1982) (finding Texas state prison conditions to violate Eighth Amendment), "a special master with a staff of attorneys and investigators and an annual budget in excess of half a million dollars is required to monitor compliance with a judicial decree seeking merely to eradicate cruel and unusual punishment." Hearings, supra note 4, app. II at 481-82. One could expect effective general monitoring to cost more. 36. Often, the governmental entities that contract out incarceration do so because they face tight budgets and hence have few discretionary funds. See Wash. Post, Sept. 22, 1985, at F9, Col. 1. Even if the sum of immediate cost saving from privatization and the expected value of future cost-saving innovations were greater than the added costs of monitoring, such an entity might not monitor adequately if the immediate cash flow were negative. 37. For an early example of suppression by official inspectors of grievous wrongs occurring within a penitentiary, apparently because the inspectors viewed themselves as advocates of the particular penal system, see H. BARNES, THE EVOLUTION OF PENOLOGY IN PENNSYLVANIA 161-62, 306-07 (1927). The Yale Law Journal no interest in acting on the agency's findings, and the agency may therefore decline to publish, or even investigate, abuses. Furthermore, administrative monitoring is subject to the phenomenon of "capture" of the regulator by the regulated entity.3" Finally, state monitors face formidable difficulties in determining societal preferences with respect to prison operation 9 and in implementing those preferences. Governmental monitors have little incentive to push prison conditions beyond a legislated or courtimposed minimum standard.41 Their job is complete when that standard is


PbS nanoparticle aggregates were synthesized in a simple aqueous reaction at room temperature, and were tested as a lithium ion anode material, with a gravimetric capacity of 374 mAh/g at C/2, and a 0.15% capacity loss per cycle. However, its half cell initial Coulombic efficiency (ICE) was only 40%, due to a combination of irreversible Li 2 S and solid electrolyte interface (SEI) formations. A custom controlled prelithiation technique was then applied to the PbS electrodes, converting the active material to Pb/Li 2 S, and consolidating the SEI prior to coin cell assembly. This brought the ICE from 40% to >97%, and allowed for immediate cycling of the electrode at high Coulombic efficiency, without further formation cycles. Upon construction of prelithiated Pb/Li 2 S vs NCM full cells, an 82% ICE was observed, with the majority of the lithium loss from the NCM. The full cells had a combined electrode capacity of 100 mAh/g at C/2.

This project maintains the required water level in the field and throws up excess water due to heavy rain fall by controlling two pumps. A wireless system is designed to provide information to the owner of the land. To ensure the security of the pumps and other equipments, there is a password protected lock system allowing the control to the authorized person only.


Every academic year, educational institutions usually have a problem related to course timetabling solved by academic staff with/without scheduling tool. The course timetabling is known to be NP-hard problem, which means that it is often impossible to provide exact solutions within a reasonable time limit. A feasible timetable must be satisfied by all hard constraints whilst soft constraints are not absolutely essential. This paper presents simulated annealing algorithm applied to solve university course timetabling problem. The algorithm includes a repair process, which ensures that all infeasible timetables that may be produced during neighbourhood search process are rectified. The algorithm evaluates the violation of four soft constraints. The computational experiment using a dataset obtained from a collaborative university was aimed to identify the appropriate setting of the cooling schedules, neighbourhood search strategies and parameters required by the proposed method. The analysis on the experimental results indicated that some of the findings were not in agreement with previous research.

Encryption is the process of encoding messages or information in such a way that only authorized users can read it. Cryptography to achieve a higher level of security. In this algorithm it becomes possible to hide the meaning of a message in unprintable characters by converting the ASCII value below 32. The main issue is to make the encrypted message undoubtedly unprintable using several times of ASCII conversions, Radix Function and a cyclic mathematical function. Dividing the original message into packets binary matrices are formed for each packet to produce the uprintable ecrypted message through the ASCII conversions, inverse cyclic mathematical and reverse radix functions are used to decrypt the unprintable encrypted message. The final message received from six times of encryption becomes an unprintable text through which the algorithm possess higher level of security without increasing the size of data or loosing of any data. Key Words— Crytography, Encryption and Decryption, Higher Level of Security, Unprintable Encrypted Message, ASCII Conversions, Radix Base, Seed. ——————————  ——————————


The realization of hydromorphologic laboratory experiments on the propagation of aggrading or degrading sediment fronts requires simultaneous measurements of the sediment feeding rate, the profile of the free surface, and the flume bed elevation. In this study, five action cameras and different image-processing techniques were employed to measure all the needed quantities automatically and with adequate temporal resolution. The measurement of the sediment feeding rate was determined by particle image velocimetry as a surrogate, correlated quantity: the surface velocity of the sediment flow along a vibrating channel was used as an upstream feeder. The profile of the free surface was measured by shooting an array of piezometers connected to the flume. Each piezometer pipe contained a buoyant black sphere that could be recognized by using tools for particle identification, thus determining the elevation of the free surface above the piezometric probe. Finally, the bed profile along the flume was measured at any instant by edge detection, locating the transition from a water layer to a sediment layer in images taken from the side of the flume. The paper describes the instrumentation and the methods, finally presenting the results obtained from a prototypal experiment. Potentialities and limitations of the proposed methods are discussed, together with some prospects on future use in systematic experimental campaigns.


OBJECTIVE
To evaluate the effectiveness of routinely used assays for schistosomiasis diagnosis in the field.

METHODS
From late November to early December 2005, 6-65 years old inhabitants from 3 endemic villages were examined by Kato-Katz technique (3 thick smears) and nylon bag sedimentation/hatching method. At the same time, dipstick dye immunoassay(DDIA), fast enzyme linked immunosorbent assay (F-ELISA), indirect haemagglutination test A (IHA-A) and B ( IHA-B) were carried out in parallel

RESULTS
1864 people were examined by stool examination with an average positive rate of 9.7%. The missing rate of DDIA was relatively stable in medium and heavily endemic areas of schistosomiasis. The missing rate of nylon bag sedimentation/hatching method was 25% and relatively stable when the number of eggs per gram of feces(EPG) was larger than 100. The average positive rate of DDIA, F-ELISA, IHA-A and IHA-B was 47.8%, 50.0%, 66.3% and 40.1% respectively. Using stool examination as the gold standard, the sensitivity of DDIA, F-ELISA, IHA-A and IHA-B was 75.3%, 65.8%, 85.6% and 76.0%; and the specificity was 55.1%, 51.7%, 35.7% and 63.6%, respectively. Among the four sero-diagnostics, the specificity, Youden index, positive likelihood rate and coincidence of IHA-B were the highest.

CONCLUSION
Kato-Katz method is more stable and effective than nylon bag sedimentation/hatching method in medium and heavily endemic areas of schistosomiasis japonica. The sensitivity and specificity of these four diagnosis kits are lower than 90%.


MOLECULAR CHAPF_~ON'ES, as has been ex#ained Mready in this ongoing series o~ reviews, are required in a wide range oi processes including folding, oiigomerization and subceiluJar ~ocaiiz- ation of poIypeptides. These processes are in competition with other pathways open to polypeptides, such as aggre- gation. The apparently diverse func- tions of chaperones are mediated by a common ability to bind a polypeptide in the non-native state and thereby pre- clude entrance into the nonproductive pathway. The chaperone must bind rapidly, since the choice of pathway is kinetically determined. That this is the case is seen most easily if the compe- tition between proper localization of a protein and its premature folding in the cytosol are considered° The outcome of each of these processes is that the protein is folded into the energetically identical, native state. Thus the choice between the pathways cannot be thermodynamically determined. With these considerations in mind, we dis- cuss one chaperone, SecB, in the hope that the emerging principles will pro- vide insights into the molecular and kinetic basis of the ~emarkable ability of all chaperones to distinguish native from non-native polypeptides. Chaperones and protein locaHzati0n SecB is one of a class of chaperones that are involved in transferring newly made proteins across membranes to the cellular locations in which they are des- tined to function. In order for transloca- tion to occur, proteins must be in a coin- petent state; that is, they can be neither folded into their native, thermodynami- cally stable, state nor aggregated I-6. The competent state is maintained by binding of a chaperone to tim nascent or just completed polypeptide 2'7. Both folding and aggregation of pro- teins can be very rapid; thus, it is clear that the rate at which a chaperone binds must be high if the chaperone is to intercept those processes and facili- tate proper localization.

Because the proposed reconfigurable resource models are difficult to be implemented or can not make full use of the resource,a new resource model is proposed.Based on the model,a hybrid real-time schedule algorithm is proposed to schedule periodic and aperiodic tasks.The algorithm partitions periodic tasks into several groups and reserves one slot on FPGA for each group.When an aperiodic task arrives,the algorithm pre-schedules all the periodic tasks' instances in current busy period and schedules the aperiodic task guaranteeing the deadlines of periodic tasks in current busy period and without influences on the tasks' execution in the next busy period.Experimental results demonstrate that the algorithm can make full use of reconfigurable resource and meet all accepted tasks' deadlines.


Largemouth Bass (LMB) Micropterus salmoides is one of the most popular sport fish in the United States and is intensively managed across much of its range. Begin - ning in 1989, Wisconsin implemented more restrictive harvest regulations for LMB, including greater minimum length limits, reduced bag limits, and a catch-and-release-only season during the spawning period across much of northern Wisconsin. We tested for trends in LMB relative abundance, growth, and angler catch and harvest in relation to LMB management policies from 1990 to 2011. We also tested for potential sport fish community responses to changes in LMB abundances using Walleye (WAE) Sander vitreus as an example. Angler catch rates and electrofishing catch per unit effort of LMB greater than 8 and 14 in increased significantly statewide. Mean length of age-6 LMB decreased significantly statewide. Release rates of LMB increased from about 80% in 1991 and then plateaued at more than 96% from 2005 to 2011. Concurrent with increases in LMB, adult WAE densities declined in lakes containing LMB. Ongoing research is being conducted to test for interactions between LMB and WAE and to test for additional environmental drivers, such as climate warming, that may be associated with increased LMB abundances. Largemouth Bass abundances have increased in Wisconsin, possibly in response to changes in harvest regulations, angler behavior, and potentially other


UPON THE DEATH OF ESIABA IROBI (196O-2OIO) on 3 May 2010, contemporary African theatre lost a distinguished playwright, stage director, actor, literary theorist, and scholar. Educated at the University of Nigeria, Nsukka (1979-83), the University of Sheffield (1989-90), and the University of Leeds (1991-97), both in England, Irobi's specialization was in drama, film, and theatre studies. Irobi was both a theatre practitioner and a scholar, and at various times taught at the University of Nigeria, Nsukka, and Liverpool John Moores University in England (1992-97), as well as at New York University (1997-2000), Towson University in Maryland (2000-2002), and Ohio University in Athens, Ohio (2002-10), all in the USA. He was on a fellowship at the Free University of Berlin, Germany, at the time of his death. However, if Irobi's life was a restless search for new horizons, his deep anchorage in the oral tradition of his Igbo ethnic group, its rituals of self-renewal, myths and legends of enigmatic and daring deityheroes, its lore of the mysteries of life and transcendence of the human spirit, its rousing chants, masquerades, and dramaturgy remained the indispensable source of his creative imagination and critical thinking.In a tribute read at Irobi's graveside at Amapu Igbengwo Umuakpara Osisioma Ngwa in Abia State, Nigeria, on 16 July 2010, his friend and colleague, the veteran stage director Eni-Jones Umuko, highlighted Irobi's talents as actor, stage director, and playwright.2 3 Umoko described in fascinating detail Irobi's role as Elesin in a production of Wole Soyinka's Death and the King's Horseman which Umoko had directed and as Styles in Fugard's Sizwe Bansi Is Dead in a production of the play directed by the renowned theatre scholar J.A.S. Amankulor (whose extensive and engaging work on traditional Igbo performance was to have an enduring influence on Irobi). Deeply moving and explicitly panegyric as most graveside tributes generically strive to be, Umoko's oration, in describing Irobi's acting generally as "trance-like" and his role as Elesin specifically as having a "hypnotic" effect on the spectators, nonetheless offers a sober and critically insightful assessment consistent with Irobi's own account of his interpretation of that role. For Irobi himself was certain that the role of Elesin, which he played first as a final-year student at the University of Nigeria, Nsukka in 1983 and then several times more between 1985 and 1989, was clearly the most "satisfying role" he played on stage, comparable only to Shakespeare's Macbeth, which he had played as a second-year student in the university, but a greater role,because of its multidisciplinary demands on the actor. You have to dance, sing, chant, mime, tell a story in the traditional African sense, play musical instruments, act, have sexual intercourse with the young bride in scene three, fondle the breasts of market women in scene one, enter into sacred/occult moments as well as secular ones in the play. You continuously oscillate from deep tragic moods to exhilarating high comic feelings in a matter of seconds while on stage. It is an awesome role, the most transcendent and spiritual and phenomenological - not merely cerebral - that I have ever played. It is arguably the most challenging role in modern world drama.'Irobi further exalted the role as typifying "indigenous African initiatory and mythopoeic acting styles," which he considered superior to Stanislavski's "magic if." He traced to that role insights that eventually led to his own development of a theory of African performance with "entrancement" or "possession" as a distinctive feature and basic canon of his own practice not only as actor but also as stage director producing numerous plays, including his own, in Nigeria, Ireland, Hungary, the USA, Spain, Sweden, Denmark, Australia, England, Portugal, and Scotland.Irobi's articulation of an African/African diasporic aesthetic theory in his essays "The Theory of Asc"4 and "Taking the Bull by the Homs"5 covers basically the same ground, though the latter strives towards greater comprehensiveness in scope, where the former illustrates its insights primarily with the drama of August Wilson, Ntozake Shange, and Djanet Sears. …

The value tax evasion relates to three aspects: government as tax collector, goods seller and goods buyer as taxpayer. The characteristics and extent of tax evasion depend on the following factors: tax rates, hidden income or unpaid tax, probability of inspection, penalty constraints, and the degree of taxpayer's risk averse as well. Government must tackle value added tax evasion through examining not only on goods-buyer but also on goods-seller.


This paper traces the development path of Taiwan's personal computer industry. Four groups of firms are identified: decedents of the TV industry in the early 1970s, decedents of the calculator industry in the late 1970s, new entrants that pioneered Taiwan's PC industry, and follow-up entrants that concentrate on PC peripherals. The technology roots of each group of firms are examined and their roles in the industry are discussed. Vertical disintegration and de-technology are two important strategies that allow small and medium enterprises to play a central role in the industry.

The majority of Irish children between 10 and 12 years of age are smartphone users, however, there is a paucity of research investigating addiction and the negative health implications of excessive smartphone use in preadolescence. Additionally, insufficient governance pertaining to child smartphone usage exists. The current study utilised a self-report paper questionnaire to determine quality of life (QoL) in preadolescent (10 – 12 years) smartphone users and nonusers. Relationships between age, usage level, addiction proneness and QoL were explored. A statistically significant difference between smartphone users and non-users was observed, with smartphone users reporting lower Qol. Age and usage level were positively related to smartphone addiction proneness score (SAPS) and SAPS was negatively related to QoL. The findings, indicating lower QoL for smartphone users, can be utilised to assist policy makers and guardians in implementing restrictions on smartphone use in preadolescence.


Summary

Nanostructured objects, often ranging from hundreds of nanometers to few microns, support a number of functions directly linked to their structural features. They are, or they will be, protagonists in biomedical applications where miniaturized activities are required. These include the interface with living systems as tissues and cells, where targeted release of drug molecules occurs, or molecular imaging methods monitoring the drug trafficking in specific cell districts. The potentials of such devices, far to be fully understood, will be assessed only when a close correlation of their functions with their structure will be established.

In this contribution we present a dextran based microdevice responsive to temperature and biodegradable. Both thermoresponsivity and biodegradability are of relevance for the potential use as drug carrier and controlled release device. The temperature behaviour, overall structure and internal architectures have been addressed with different methods.

In Scandinavian languages there are many popular bird names, most of which have been recorded at the dialect archives in the Nordic countries. The thesis concentrates on the bird names for snipes, i.e. the common snipe, the great snipe, the jacksnipe and the woodcook, in all approx. 330 different names. Some of these are recognized in all Scandinavia, while others are only sparsely confirmed in single dialects.An especially large amount of names refers to the common snipe, mainly due to its typical vibration sound. While the sound mostly resembles a certain unobtrusive whinny from a horse or bleat from a goat or a sheep, many of the popular names contain words associating to these animals. Names describing a particular creaking sound mostly refer to the woodcock. Fairly common are names describing a protruding beak, which is a characteristic feature of all snipes.In order to present a complete semantic and etymological picture, all words forming part of the names have been identified and sorted by category, i.e. words indicating a common implicit meaning. The categories have in turn been divided into two main groups: words describing different sounds, and words describing visual impressions. In addition, names describing popular beliefs and those transferred from other bird species are presented.Factors that influence origin, formation, existence and development of bird names have especially been taken in consideration. With the etymological discussion forming the necessary background, ethnological as well as cultural influences have been added in order to complete the picture of the naming process. One important factor in this process is man's need of identification and classification of phenomena in his environment. Another main ingredient is the presence vs. lack of affect in the process. In the popular naming process a striking sound along with a particular appearence have caused many affected names, while scientific names mostly refer to visual, non-affected impressions.Due to man's present lack of everyday connection with nature many of the popular bird names presented are no longer in use. However, some of the names are proven to be fairly young, which shows that the process of popular classification and naming is still a functioning part of our language and culture.


This study aims to assess the relationship between R&D and economic growth in terms of their ability to understand R&D management. In the paper, the algorithm of actions was used, which allows ensuring interconnection, sequence of work, validity of the choice of the methods used, and defining key factors over a long period. The following methods of the empirical study were used: analysis of the provision of level development; regional analysis of the data; correlation analysis. Based on correlation analysis the impact of economic growth on R&D was investigated, which is expressed by such variables as the number of organizations engaged in R&D, internal expenditures in R&D, expenditures for technological innovations, number of employees in R&D. The data were obtained from the World Bank, the Eurasian Economic Union, and the statistical yearbook of Kazakhstan for 2009–2019. The results obtained show that all determinants correlate not only with the GDP but with each other as well. According to the findings, viewing the GDP level, there is a positive and negative correlation link between such two factors as 'the number of research organizations' and 'R&D technological innovations'. These coefficients of correlation between GDP and independent factors selected for the analysis are significant, i.e. they can significantly affect the value of the GDP. The obtained results are useful in formulating the R&D development management strategy.

Rapid development of modern communications has initiated essential requirements for providing efficient algorithms that can solve the routing and wavelength assignment (RWA) problem in satellite optical networks. In this paper, the bee colony algorithm optimization based on link cost for RWA (BCO-LCRWA) is tailored for satellite networks composed of intersatellite laser links. In BCO-LCRWA, a cost model of intersatellite laser links is established based on metrics of network transmission performance namely delay and wavelengths utilization, with constraints of Doppler wavelength drift, transmission delay, wavelength consistency and continuity. Specifically, the fitness function of bee colony exploited in the proposed algorithm takes wavelength resources utilization and communication hops into account to implement effective utilization of wavelengths, to avoid unnecessary over-detouring and ensure bit error rate (BER) performance of the system. The simulation results corroborate the improved performance of the proposed algorithm compared with the existing alternatives. key words: routing and wavelength assignment, satellite optical networks, bee colony algorithm optimization, link cost, fitness


The chemical composition of essential oil, isolated from Globularia alipum by hydrodistillation, was analysed by GC and GC/MS. A total 39 compounds representing 98.9% of the oil were identified in Boutaleb population, and 89.7% of the total oil in Khenchela population. The essential oil of G. alipum is Characterized by a high rate of hexadecanoic acid (palmetic acid), 14.64% for Boutaleb population and a rate of 29.52% for Khenchela population. Other major compounds are present in the essential oils of G. alipum, the phytol isomer (9.9-5.43%); (Z.Z)-6,9-cis-3,4-epoxy-nonadecadi (8.27-5.45%); 1,2-Benzene dicarboxylic acid-bis (4.68-6.09%); L-linalool (3.49-3.83%) and the heptadecane (2.29-3.28%) respectively for Boutaleb and Khenchela populations. To test the antibacterial activity of essential oil of G. alipum, eleven bacteria are used in this study. The oil showed a significant effect against Gram-negative bacteria, and modest antibacterial activity against Gram-positive bacteria. The populations of G. alipum studied showed a diploid chromosome number with 2n = 2x = 16, and a basic chromosome number x = 8.

This study presents a consensus region approach to designing distributed consensus protocols for multi-agent systems with general continuous-time linear node dynamics. The consensus region approach has a favourable decoupling feature, which decouples the design of the feedback gain matrices of the consensus protocols from the communication graph. Multi-step algorithms are presented to construct the fixed-gain consensus protocols, which requires the smallest non-zero eigenvalue of the Laplacian matrix. To remove this limitation, distributed adaptive protocols with time-varying coupling weights are designed for the cases with undirected and directed graphs, which can be implemented in a fully distributed fashion. The robustness issue of the adaptive protocols in the presence of external disturbances is also discussed. For the case where there exists a leader of bounded unknown control input, distributed discontinuous and continuous controllers are designed to solve the distributed tracking problem.


The main focus of this paper is the impact of efficiency losses, related to public capital stock, on the prospects of economic growth in democratic and autocratic political environments. We introduce a distinction between two types of efficiency loss: along with the loss of public capital during its accumulation, we take into account the process of capital stock depreciation. We demonstrate that the decrease in efficiency of any type makes the probability of long-run growth higher for autocracies; however, in the presence of high efficiency, democracies tend to perform better. The results were obtained by formal analysis and computational experiments, realized on the basis of an original dynamical model.


617 All nine of these essays offer full treatments of their various topics without sacrificing readability. The ability of readers to follow the text is greatly enhanced as well by the many high-quality maps that appear in the book. By bringing these essays together under a single cover, Smith and the University of Tennessee Press have performed a welcome service for students of Shiloh, its battlefield, and the history of both.


My title advertizes a paradox. The characteristic complaint of the sceptic is that others make assumptions they are not entitled to make. A philosophical sceptic is committed to a systematic refusal to accept such assumptions in the absence of the kind of justification they think is required. A sceptic who, none the less, helps himself to such an assumption, seems to be caught in a paradoxical position. This is the kind of situation in which, it seems, certain eighteenth-century sceptical philosophers were placed in relation to the 'principle' of natural order. They did not doubt that there is such a principle, that there is a source or ultimate cause of the order to be found in the universe. And yet, on their own terms, is not the existence of such a principle something we should expect them to have doubted? What I shall try to do in this lecture is to bring out why they did not doubt the existence of such a principle and how serious their failure to do so is for their sceptical position.


RAID must work. A compelling challenge in software engineering is the analysis of flexible modalities. Continuing with this rationale, the influence on hardware and architecture of this has been well-received. On the other hand, the Ethernet alone can fulfill the need for classical information. We skip a more thorough discussion due to resource constraints. Our focus in this paper is not on whether the little-known Bayesian algorithm for the exploration of the Internet by Taylor and Robinson [11] runs in Ω (n2) time, but rather on motivating an analysis of DHCP (Bub). Even though conventional wisdom states that this issue is never fixed by the analysis of linked lists, we believe that a different approach is necessary. We view cryptography as following a cycle of four phases: storage, prevention, exploration, and storage. Two properties make this approach different: Bub controls "smart" theory, and also we allow Moore's Law to control encrypted communication without the investigation of active networks. To put this in perspective, consider the fact that famous hackers worldwide entirely use A* search to accomplish this intent. The shortcoming of this type of solution, however, is that erasure coding and kernels can cooperate to realize this objective. Our contributions are twofold. We present a novel framework for the exploration of evolutionary programming (Bub), which we use to disconfirm that suffix trees can be made highly-available, certifiable, and read-write. We demonstrate that while the little-known permutable algorithm for the synthesis of expert systems by L. Zheng follows a Zipf-like distribution, journaling file systems and the transistor can synchronize to solve this grand challenge. The rest of this paper is organized as follows. To begin with, we motivate the need for linked lists. Further, we place our work in context with the prior work in this area. We confirm the construction of rasterization. Ultimately, we conclude.


The Tapinggou copper-molybdenum deposit,located in the north section of the Daxinganling polymetallic metallogenic province,is of porphyry type discovered in recent years.The deposit is medium-sized,buried in the depth of 34.6 m and more,with orebodies dominated by Mo in sulfide minerals.The Cu-Mo deposit is composed of ten molybdenum orebodies and one copper body.The grade of molybdenum ranges from 0.071% to 0.268%.The maximum extension of orebody is 930 m,with the thickest monolayer of 106.89 m.The metal content is preliminarily estimated in excess of 20000 tons.


In this paper an analysis of the nonlinear dynamic behavior and control of an atomic force microscope system is described. Phase plane trajectories, spectrum analysis, bifurcation analysis, the Poincare cross-section, the maximal Lyapunov exponent, and other numerical analysis methods were used to observe and verify the dynamic characteristics and the differential equations for the system. The results showed that at specific excitation frequencies, the system will exhibit nonlinear behavior that may be cyclic, multi-cyclic or acyclic. A Psim circuit simulation using the same parameters showed the same nonlinear behavior, as did laboratory circuit implementations. The results also showed than an understanding and control of the dynamic characteristics would not be an easy task. However, they could be used as a basis for the suppression and control of nonlinear behavior and vibration in atomic force microscope systems. A proportional-derivative system was also used, with particle swarm optimization, to find the control parameters Kp and KD and a fuzzy controller was used to compare the results. The controller simulation and hardware implementation both effectively inhibited the nonlinear behavior and were most helpful for the control and enhancement of measurement accuracy.


Grossly visible lesions of the ctenidia and occasional mortalities in Japanese oyster Crassostrea gigas from the Atlantic French coast were reported in 1992-1993. From August 1992 to March 1993, 235 living oysters were collected to determine the cause of tissue lesions and mortalities. Microscopical examination of fixed, stained sections revealed that 53 2% of these oysters had ctenidia and mantle lesions associated with irregular basophllic and Feulgen positive cytoplasmic inclusion bodies. Ultrastructurally, the infectious agent was a chlamydia-like organism. Indirect fluorescent and peroxidase conjugated antibody tests suggested that this agent might share common antigens with the prokaryotic agent Chlamydia psittaci, strain ovis


Objective To study the significance of coronary calcification by electric beam computed tomography (EBCT) in elderly patients. Methods A routine EBCT was taken in 77 patients with coronary heart disease and controlled patients. The diagnosis of coronary heart disease was depended on history of myocardial infarction or on coronary angiography greater than 50% stenosis in 44 patients.Thirty three persons with normal coronary artery on coronary angiography or normal thallium study and clinically ruled out coronary heart disease as control group.The coronary artery calcification score was calculated respectively in two groups. Results There was no difference in age, serum lipid levels and history of hypertension between two groups. The coronary artery calcification scores (median, 25% 75% quantiles) in patients with coronary heart disease were significantly higher in LAD 〔(225,87 5 444) vs (6,0 95), P 0 01〕, LCX 〔(83,9 176) vs (1,0 47), P 0 01〕〕, RCA 〔(90 5,1 5 302 5) vs (2,0 84), P 0 05〕 and TCS 〔(585,201 5 1 156) vs (75,0 425), P 0 01〕 compared with that in control group. The difference of coronary scores in LM was not significant The percentage of the total calcification score(TCS) higher than 556 were 52 3% in patients with coronary heart disease and 21 2% in the control group(χ 2=7 650, P 0 01). The sensitivity and specificity of TCS more than 556 in diagnosis of coronary heart disease are 52 3% and 78.8%. The positive predictive value and negative predictive value are 76 6% and 55 3%, respectively. Conclusions The coronary calcification score of EBCT in elderly patients with coronary heart disease is significantly higher than that in control group .It may be helpful in diagnosing coronary heart disease, but its normal ranges in the elderly still need to be further determined.


There are many ways in which a person can identify a person. Biometric authentication uses a wide variety of methods, including fingerprint, voice, face, iris, the lines of the palm, and vein distribution. Of the various authentication methods, the voice authentication method is a very effective authentication method in terms of security, convenience, and economy. Because voice signals contain a lot of information, the results of differentiating personality will vary depending on how bandwidth-limited is done. In this study, the identification rate difference according to the bandwidth-limited of the voice signal was confirmed by using a sound color marker that expresses the voice signal into seven colors. As a result of the experiment, it was possible to identify the same person or others in various cases of bandwidth-limited voice signal only by comparison of sound color marker. Also, it can be seen that, even if the bandwidth is limited to various forms, all of them have individual characteristics. As a result, the sound color marker reflects the bandwidthlimited individual characteristics, so that even if bandwidth-limited, identification of the same person or other person is possible.


In this paper,the Cohen-Grossberg neural networks with mixed delays and impulses are considered.Applying the idea of M-matrix theory and inequality technique,several new sufficient conditions are obtained to ensure global exponential stability of equilibrium point for impulsive Cohen-Grossberg neural networks with mixed delays and impulses.These results generalize a few previous known results and remove some restrictions on the neural network.Two examples are given to show the effectiveness of the obtained results.


We extend the concept of monostatic aspect diversity for improved automatic target recognition (ATR) to a bistatic synthetic aperture radar (SAR) platform. We derive the probability of error with respect to the number of aspects used for a simple two-target template-matching classification system. The validity of the error prediction is confirmed using simulated bistatic SAR images. Our results demonstrate the ATR benefits of supplementing monostatic SAR images with one or more bistatic SAR images.


Experiments have been performed to study the combustion criteria of aluminum particles at atmospheric pressure. The primary goal is to quantify the outcome for a particle into which thermal energy has been deposited. Experiments utilized instantaneous joule heating of an aluminum wire. Once the particle was generated, it fell under gravity and the flight was recorded by video; in some cases, the ignited particle quenched or fragmented, and the residue was collected for SEM and EDS imaging. This provided information related to the aluminum oxide shell which was formed when combustion occurred. These experiments produced particles of approximately 150450 microns in the arc heating tests. In a second set of experiments, particles were produced under more observable time scales. This provided observation of the oxide skin, which is known to influence the ignition process. This experiment utilized a pressure pulse to eject a small droplet of molten aluminum through a small orifice. From this experiment, particle sizes ranging 2–3 mm were produced.Copyright © 2012 by ASME


While the National Health Education Standards focused interest and attention on student (consumer) health literacy, equal attention should be given to teacher (provider) health literacy. Teacher health literacy may be defined as "the capacity of teachers to obtain, interpret, and understand basic health information and services, with the competence to use such information and services in ways that enhance the learning of health concepts and skills by school students." This paper reviews a traditional model for school health teacher preparation, then presents an alternative, university field-tested model for enhancing health literacy in teacher education. This new model presents an innovative instructional paradigm, the Child and Adolescent Health (CAH) Logic Framework. This training model (vision) illustrates and emphasizes the link between child and adolescent health research and theory, CAH information, and application to health education, public policy, medical care, and health advocacy.


The evolution of the sintering neck sizes was observed in experiments on the conductive powder particles, based on which a model that describes the distributions of the current density and the temperature increase in the spark plasma sintering (SPS) process was developed. The simulations show that the sintering neck with smaller size grows prior to the neck with larger size. The reason is that the current density at the smaller necks is higher than that at the larger necks, hence there is a higher temperature increase at the same sintering stage. As a consequence, the neck size distribution becomes homogeneous with the densification process. A unique 'self-adjusting' mechanism for the neck growth was proposed for the SPS process, which explains the advantageous features of SPS densification.


We study the global geometry of solutions to Einstein's (vacuum or matter) constraint equations of general relativity, and we establish the existence of a broad class of asymptotically Euclidean solutions. Specifically, we associate a solution to the Einstein equations to any given weakly asymptotically tame seed data set satisfying suitable decay conditions, a notion we define here. Such a data set consists of a Riemannian metric and a symmetric two-tensor prescribed on a topological manifold with finitely many asymptotically Euclidean ends, as well as a scalar field and a vector field describing the matter content. The Seed-to-Solution Method we introduce here is motivated by a pioneering work by Carlotto and Schoen on the so-called localization problem for the Einstein equations. Our method copes with the nonlinear coupling between the Hamiltonian and momentum constraints at the sharp level of decay, and relies on a linearization of the Einstein equations near an arbitrary seed data set and on estimates in a weighted Lebesgue-Holder space adapted to the problem. Furthermore, for seed data sets enjoying stronger decay and referred to as strongly asymptotically tame data, we prove that the seed-to-solution map (as we call it) preserves the asymptotic behavior as well as the ADM mass of the prescribed data. Motivated by a question raised by Carlotto and Schoen, we define an Asymptotic Localization Problem, which we solve at the sharp level of decay.


The concept of"stereotype"was introduced in China 20 years ago.In these 20 years,researches about stereotype in communication studies were focused on four fields:stereotypes in media content,the reason and the effect to use the stereotype in media content,the use of the image which was anti-stereotype,stereotype in journalistic routines.After examine all the literatures,the author argued that,there was two unresolved problems in those researches about stereotypes:what is the precise meaning of stereotype,and then,what is the relationship between the stereotype and mass communication.

A key issue when designing and implementing large-scale publish/subscribe systems is how to efficiently propagate user subscriptions among the brokers of the system. In this paper we contribute the notion of broker subscription summaries and accompanying distributed and scalable algorithms for subscription summary propagation and event filtering and routing. In addition we present a performance analysis, quantifying the associated benefits. Our results show that the proposed mechanism (i) introduces significant performance gains in terms of saved network bandwidth (up to orders of magnitude), required storage space, and processing capacity requirements at each broker, and (ii) is highly scalable, with the bandwidth required to propagate subscriptions increasing only slightly, even at huge-scales.

Glycogen depletion has frequently been shown to result in a decrease in respiratory exchange ratio (RER). However, the metabolic response to glycogen depletion has generally been studied in overnight fasted subjects or in subjects who were already fatigued, or hypoglycaemic, or both, raising the question of whether the differences seen were due to general "carbohydrate deficiency" or due specifically to muscle or liver glycogen depletion. If euglycaernia and especially hyperglycaemia is maintained, the "carbohydrate deficiency" is overcome. In addition, because insulin stimulates muscle glucose uptake and not liver glucose uptake during euglycaernia (except at very high concentrations), insulin infusion would differentiate between liver and muscle glycogen depletion, since if the decrease in RER previously observed is abolished with insulin infusion while euglycaemia is maintained, this would indicate that the decrease is specifically due to muscle glycogen depletion. Thus the aim of this study was to investigate the metabolic effect of glycogen content while an adequate amount or an excess of carbohydrate was provided in the form of an intravenous glucose infusion and when plasma insulin concentrations are raised. Thirty-two moderately trained cyclists followed an exercise protocol to deplete muscle glycogen, whereafter 21 followed a lowCHO diet (low glycogen; LG) for 48 hours and 11 maintained their normal diet (normal glycogen; NG). All subjects ingested a small meal (±30 g CHO) 3 hours before exercising at 700/o of V02 max for 145 min. During exercise, 8 LG and 6 NG received an infusion of glucose to maintain euglycaemia (LGE and NGE, respectively) and 5 LG received a euglycaemic, hyperinsulinaemic clamp (LGEI). In addition, 8 LG and 5 NG received a glucose infusion to maintain plasma glucose concentrations at ±9 mmol/1 (LGH and NGH. respectively). V~ was measured every 20 min during exercise and RER, CHO and fat oxidation were calculated. At the same time-intervals, blood was drawn via an indwelling cannula for determination of plasma concentrations of glucose (G), insulin (INS), glucagon (GG), growth hormone (GH), catecholamines.. and serum free fatty acids (FFA). A U-C-glucose tracer was used for measurement of glucose oxidation. A biopsy was taken from the vastus lateralis before and after completion of the ride for measurement of muscle glycogen content. Pre-exercise resting FF A and norepinephrine (NE) concentrations were higher and RER lower (p<0.05) after glycogen depletion. During exercise, total fat oxidation (F10,) in LGE (126±6 g (mean±SEM)) was significantly (p<0.05) higher than in NGE (76±12 g) or LGEI (88±18g) and in LGH (72±7 g) was significantly (p<0.05) higher than in NGH (33±1 l g). LGEI and LGH were similar with respect to F,otRates of glucose oxidation (R,,J increased progressively in all groups (p<0.05). Total glucose oxidation (G0 x) was significantly (p<0.05) lower (389±44 mmol) in LGE than in LGH


In this paper, a broadband Fabry-Perot cavity leaky wave antenna is proposed. It consists of a parabolic-shape reflector acted as ground plate, metallic grating-shape FSS acted as cover, and an open-ended waveguide as the feeder. Taking use of parabolic-shape reflector the performance of bandwidth for gain can be improved obviously. A prototype antenna operating at 14GHz is designed. Simulation results show that common bandwidth of 8% for gain-drop <1 dB and S11<−10dB is obtained.


This article addresses the problem of screening for variables with high correlations in high-dimensional data in which there can be many fewer samples than variables. We focus on threshold-based correlation screening methods for three related applications: screening for variables with large correlations within a single treatment (autocorrelation screening), screening for variables with large cross-correlations over two treatments (cross-correlation screening), and screening for variables that have persistently large autocorrelations over two treatments (persistent-correlation screening). The novelty of correlation screening is that it identifies a smaller number of variables that are highly correlated with others compared with identifying a number of correlation parameters. Correlation screening suffers from a phase transition phenomenon; as the correlation threshold decreases, the number of discoveries increases abruptly. We obtain asymptotic expressions for the mean number of discoveries and the phase transition thresholds as a function of the number of samples, the number of variables, and the joint sample distribution. We also show that under a weak dependency condition, the number of discoveries is dominated by a Poisson random variable giving an asymptotic expression for the false-positive rate. The correlation screening approach yields tremendous dividends in terms of the type and strength of the asymptotic results that can be obtained. It also overcomes some of the major hurdles faced by existing methods in the literature, because correlation screening is naturally scalable to high dimensions. Numerical results strongly validate the theory presented here. We illustrate the application of the correlation screening methodology on a large-scale gene-expression dataset, revealing a few influential variables that exhibit significant correlation over multiple treatments.

In an attempt to converge the benefits of preparation of mixed oxides from layered double hydroxide (LDH) precursors with the high activity of Cu-based systems in methane combustion and taking simultaneously into consideration an expected Cu-Ce synergistic effect, the first part of this work is focused on new LDH-derived Cu-Ce-MgAlO mixed oxides catalysts. Thus, a series of five Cu(x)CeMgAlO mixed oxides with different copper contents (x) ranging from 6 to 18 at. % with respect to cations, but with fixed 10 at. % Ce and Mg/Al atomic ratio of 3, was prepared by thermal decomposition at 750 °C of precursors consisting of poorly crystallized LDH and boehmite (AlOOH) phases. Powder X-ray diffraction (XRD) was used to characterize the crystalline structure and scanning electron microscopy coupled with energy dispersive X-ray spectroscopy (SEM-EDX) was used to monitor the morphology and chemical composition of both as prepared and calcined materials. Additionally, the textural properties and the reducibility of the mixed oxide catalysts were studied by nitrogen adsorption/desorption and temperature programmed reduction with hydrogen (H2-TPR) techniques, respectively. X-ray photoelectron spectroscopy (XPS) was used to determine the chemical state of the elements on the catalyst surface and the diffuse reflectance UV-Vis spectroscopy (DR UV-Vis), to obtain information about the stereochemistry and aggregation of copper in the Cu-containing mixed oxides. It has been shown that the mixed oxide catalysts have slit-like bimodal mesopores and relatively high surface areas, which regularly decrease from 169 to 108 m2 g-1 with increasing the Cu content, and consist of periclase-like Mg(Al)O mixed oxide and CeO2 fluorite phases, except for Cu(18)CeMgAlO, which also contains well developed CuO crystallites. At low Cu content, highly dispersed Cu-doped ceria crystallites coexist with oligomeric (Cu2+– O2-– Cu2+)n2+ species in the Mg(Al)O matrix, while at high Cu content larger ceria crystallites less exposed on the catalyst surface coexist with separate CuO particles enriching the surface. Their catalytic properties in the total oxidation of methane, used as a volatile organic compound (VOC) model molecule, were evaluated and compared with those of an industrial Pd/Al2O3 catalyst. Their catalytic behavior was explained in correlation with their physicochemical properties. The Cu(II)/Cu surface atomic ratio was shown to be a key factor controlling the catalytic activity of the Cu(x)CeMgAlO catalysts. Indeed, with the highest Cu(II)/Cu surface atomic ratio, the Cu(15)CeMgAlO mixed oxide was shown to be the most active catalyst in this series, with a T50 (temperature corresponding to 50 % methane conversion) value of only ca. 45 °C higher than that of an industrial Pd/Al2O3 catalyst. Its enhanced catalytic activity was attributed to an excellent dispersion of CuO, oligomeric (Cu2+– O2-– Cu2+)n2+ species coexisting with tiny not XRD-visible CuO crystallites strongly interacting with ceria, which leads to a strong synergy effect between Cu and Ce. The catalytic sites are located at the CuO-CeO2 particles interface. Decreasing the calcination temperature of the Cu(15)CeMgAl precursor from 750 to 650 and 550 °C resulted in mixed oxides with higher surface areas and, hence, higher catalytic activities in terms of T50, which for the Cu(15)CeMgAlO-550 system is only ca. 25 °C higher than that of the industrial Pd/Al2O3 catalyst. However, in terms of intrinsic reaction rates the most active catalyst was that calcined at 750 °C accounting for a strengthened Cu-Ce interaction with increasing calcination temperature. The influences of the contact time and of the methane concentration in the feed gas on the catalytic performances of the Cu(15)CeMgAlO catalyst calcined at 750 °C have also been investigated and its good stability on stream was evidenced.
In the second part of this work, in order to improve the catalytic performance of the Cu(15)CeMgAlO mixed oxide catalyst calcined at 750 °C in the total oxidation of methane reaction, it was promoted with different transition-metal cations M (M = Mn, Fe, Co and Ni), an enhanced synergy effect between Cu and Ce in their presence being expected. Thus, two series of multicationic mixed oxides were prepared by the controlled thermal decomposition at 750 °C of their corresponding LDH precursors synthesized by coprecipitation at constant pH of 10 under ambient atmosphere. The first series of catalysts consisted of four M(3)CuCeMgAlO mixed oxides containing 3 at. % M (M = Mn, Fe, Co, Ni), 15 at. % Cu, 10 at. % Ce (at. % with respect to cations) and with Mg/Al atomic ratio fixed to 3. Taking into consideration that Co was found to be the best promoter and that the content of the transition-metal promoter is known to strongly influence the trimetallic synergistic interaction and, hence, the catalytic performance of the mixed oxide, the second series consisted of four Co(x)CuCeMgAlO mixed oxides with x = 1, 3, 6 and 9 at. % Co, while keeping constant the Cu and Ce contents and the Mg/Al atomic ratio. All the mixed oxides were characterized using a battery of techniques including XRD, transmission electron microscopy (TEM), SEM-EDX, XPS, nitrogen adsorption/desorption at –196 °C, H2-TPR, and DR UV-Vis, while thermogravimetric and differential thermal analyses together with XRD were used for the LDH precursors. The latter consisted of well-crystallized LDH phase together with poorly-crystallized boehmite (AlOOH) side phase. All the mixed oxides calcined at 750 °C were mesoporous materials with surface areas lower than that of the parent CuCeMgAlO mixed oxide, in the range from 66 to 78 m2 g-1, and consisted of periclase-like Mg(Al)O mixed oxide, CeO2 fluorite, and CuO tenorite phases. The segregation of the CuO tenorite phase was shown to increase with the Co content in the Co(x)CuCeMgAlO series. The nature of the transition-metal M for the M(3)CuCeMgAlO catalysts series and the Co content for the Co(x)CuCeMgAlO series strongly influence, in a complex manner, their physicochemical characteristics and, hence, their catalytic performance in the complete oxidation of methane. No clear correlations could be observed between the catalytic performance and the physicochemical characteristics of the mixed oxide in the M(3)CuCeMgAlO series. However, their enhanced activity compared to the M-free CuCeMgAlO system was attributed to an enhanced synergistic interaction between Cu and Ce in the presence of transition-metal cations M. On the other hand, the catalytic activity in the Co(x)CuCeMgAlO series was shown to increase with increasing of both the Co3+, Cu2+ and Ce4+ surface concentrations and the catalyst reducibility, unambiguously demonstrating that the synergistic interaction between these species is a key factor controlling their catalytic behavior in the complete oxidation of methane. The Co-promoted CuCeMgAlO mixed oxide with 3 at. % Co was shown to be the most active catalyst in both series, with a T50 value of 438 °C, which is only 19 °C higher than that of a reference Pd/Al2O3 catalyst. Notably, this T50 value is ca. 25 °C lower than that observed for the unpromoted CuCeMgAlO system, accounting for the improved performance of the Co-promoted catalyst. Its enhanced catalytic activity was attributed to an excellent Cu-Co-Ce synergistic interaction. A good stability on stream of the Co(3)CuCeMgAlO catalyst was also noticed.


A stochastic model for a computer system is developed by providing hardware redundancy in cold standby. The hardware and software are considered as the two main components of the system having operative and complete failure modes. A single service facility is used to repair the hardware component and also to upgrade the software. The service facility is subjected to failure while repairing the hardware. Treatment is given to the failed service facility so that it can resume the assigned repair activities with full efficiency. The up-gradation of the software is done either at its outdated features or when it fails to follow the instructions properly in order to complete the assigned jobs. The failure times of the components and service facility follow negative exponential distribution while the distributions of hardware repair, software up-gradation and treatment time of the service facility are taken as arbitrary with different probability functions. The expressions for some reliability measures are derived in steady state by using semi-Markov process and regenerative point techniques. The graphical study of these measures has also been made for arbitrary values of the parameters.


The kinetics of initiation of metathesis polymerisation of methyl-substituted norbornenes initiated by complexes of the type [Mo(CHR1)(NC6H3Pri2-2,6)(OR2)2][R1= But, CMe2Ph; OR2= OCMe3, OCMe(CF3)2] reveal a zero-order dependence on monomer concentration in some cases; syn→anti alkylidene conversion of the initiator is proposed as the rate-limiting step.


BACKGROUND AND OBJECTIVE
This study was done to estimate the seroprevalence rate among Nigerian patients presenting to hospital with neurosurgical disease.

PATIENTS AND METHOD
We reviewed our patients' hospital records from October 1996 to October 2001 for clinical presentation and diagnosis, cranial CT findings, results of retrovirus screening and mode of management.

RESULTS
Sixteen (10 males and 6 females) out of 601 patients screened for HIV by ELISA were confirmed by Western Blot to be positive, giving a seroprevalence rate of 2.7% . Twelve of the HIV-positive patients were asymptomatic for HIV disease.

CONCLUSION
There is a low but definite risk of HIV transmission to health workers managing patients with surgical lesions of the brain in areas where HIV is prevalent. Asymptomatic seropositive HIV patients with surgically curable intracranial disease should be managed with the most minimally invasive procedure appropriate for the surgical lesion under universal protective measures.


An analysis is presented of a new bus structure, called the hierarchical bus structure. An exact analytical model of a two-level hierarchical bus is developed. The results from both the analytical model and simulation are shown. They indicate that a hierarchical bus would be a more cost-effective bus structure than the conventional multiple-bus and partial-multiple-bus structures.<<ETX>>


Abstract : An apparatus, the burner rig, used to evaluate materials for use in gas-turbine engines operating in a marine environment, is described. Testing procedures are outlined, and results are discussed in relation to gas-turbine engine tests. The rig operates by the combustion of diesel oil or jet fuels. Injected seawater and the products of combustion pass over as many as 48 test specimens. Although the rig operates at atmospheric pressure and low velocities, it can generate a test environment that results in hot corrosion as found in actual engines.


s Short Talks Akman, Murat (University of Connecticut, USA) Small perturbations of elliptic operators in uniform domains satisfying the CDC Abstract: In this talk, we study small perturbations of elliptic operators in uniform domains satisfying the capacity density condition (CDC). In particular, we focus on the following problem: suppose that we have "good estimates" for the Dirichlet problem for a uniformly elliptic operator L0, under what optimal conditions, are those good estimates transferred to the Dirichlet problem for uniformly elliptic operator L which is a perturbation of L0? We prove that if discrepancy between L0 and L satisfies certain smallness assumption then the elliptic measure ωL corresponding to L is in the reverse Hölder class with exponent 2 with respect to the elliptic measure ωL0 corresponding to L0. Our work extends the classical result of Dahlberg and Fefferman, Kenig, and Pipher in Lipschitz domains, and Milakis, Pipher, and Toro in chord-arc domains to uniform domains satisfying the CDC. This is a joint work in progress with Steve Hofmann, José Maŕıa Martell, and Tatiana Toro.

The advent of powerful computing platforms coupled with deep learning architectures have resulted in novel approaches to tackle many traditional computer vision problems in order to automate the interpretation of large and complex geospatial data. Such tasks are particularly important as data are widely available and UAS are increasingly being used. This document presents a workflow that leverages the use of CNNs and GPUs to automate pixel-wise segmentation of UAS imagery for faster image processing. GPU-based computing and parallelization is explored on multi-core GPUs to reduce development time, mitigate the need for extensive model training, and facilitate exploitation of mission critical information. VGG-16 model training times are compared among different systems (single, virtual, multi-GPUs) to investigate each platform's capabilities. CNN results show a precision accuracy of 88% when applied to ground truth data. Coupling the VGG-16 model with GPU-accelerated processing and parallelizing across multiple GPUs decreases model training time while preserving accuracy. This signifies that GPU memory and cores available within a system are critical components in terms of preprocessing and processing speed. This workflow can be leveraged for future segmentation efforts, serve as a baseline to benchmark future CNN, and efficiently support critical image processing tasks for the Military.
