This book explores how comedian Stephen Colbert's satiric views of American life have captured the imagination of viewers around the world—and sharpened these individuals' own critical interpretations and opinions on current events.
 Stephen Colbert may be "just a comedian"—one not all audiences find funny, especially among those who have been mercilessly lampooned by him—but there is no arguing that the condescending, bombastic, and largely ignorant pundit he plays on Comedy Central has brought awareness of current events and political happenings to a substantially larger portion of the American population.
 The only available biography on Stephen Colbert, this book examines his life story and details how he became one of the most influential people on current American culture. Beginning with coverage of Colbert's childhood, the chapters discuss his education, highlighting his interest in drama; describe his introduction to the world of comedy; review his contributions as a "correspondent" on The Daily Show with Jon Stewart; and focus on Colbert's accomplishments and antics as the star of his faux news program that debuted in the fall of 2005, The Colbert Report.

This report covers Quarters 8 and 9 (February 6, 1988--August 5, 1988). During this period, extensive experimentation was carried out under Task A, the Optimization of Electron Beam Precharger Geometry. Concurrently, new experiments were performed on free electron charging which essentially completed the work called for under Task B. The progress on both Tasks is briefly summarized in this section and is discussed in detail in the following sections. 24 figs., 3 tabs.


This report investigates the current state of physical (mechanical) robotics, automated warehousing approaches and assistive technologies in relation to the storage, handling and processing (particularly digitisation) of natural history collections.
 Robotics can sound futuristic, however we provide case studies that show many and growing examples of physical automation in the natural history and cultural heritage sectors, including barcodes and conveyor belts for digitisation; robots that handle multiple vials for molecular and genetic work; robots for use in in display or exhibition contexts; and automated warehousing of library collections. We provide a non-exhaustive example of an end to end workflow of storage, retrieval and processing and discuss aspects of the tools and challenges relevant to these stages. The Distributed System of Scientific Collections (DiSSCo), a new Research Infrastructure for natural science collections, should build on this, leading a future programme of pilots that develop understanding of independent stages, and can be connected to make progress towards end-to-end solutions.
 Robots, or automated systems, excel at repetitive tasks, and are developing rapidly to be able to handle more complex object types, at lower cost. High volume, high variety of objects, and considerations such as fragility are not unique to the natural history sector - they apply for example to major retail operations - however natural history collections do offer some of the more extreme examples of these challenges, and in particular are not replaceable. Increased consistency of storage units is likely to be a critical factor in enabling automated handling in future, as well as looking at automation possibilities when new collections storage spaces are developed and built. Engagement with industry and subject matter experts has been patchy and again we recommend that DiSSCo help to ensure a joined up engagement with the right incentives in place, and with clear communication of requirements and challenges for shared R&D.
 When examining return on investment for particular automation, collections-holding institutions need to consider not only time and cost of automation compared to human labour, but wider factors including: health and safety such as physical environment and repetitve strain injury; security; quality and consistency of outputs; degree of criticality in response times (e.g. if digitising on demand); effective use of spaces; and freeing up staff to conduct other tasks.
 Purely software-based automation is outside the scope of this report, but is also in increasing use and has enormous potential, for example to transform the extraction of label and specimen data at scale from images. The challenges of managing and digitising collections at scale under DiSSCo are likely to require a combination of hardware and software automation approaches.

Parallelization strategies for nonequilibrium molecular dynamics (NEMD) simulations of heat conduction in heterogeneous materials are presented. In particular, a previously published algorithm involving the pair decomposition of three-body potentials is extended for heterogeneous materials. In addition, a novel and linear scaling scheme, also based on pair decomposition of three-body terms, is introduced for the calculation of the heat flux. The distributed-computing-based implementation of this algorithm is outlined and its speed-up characteristics are demonstrated to be close to ideal. Example NEMD simulations using the new algorithm are performed for the Si/Ge superlattice based on the three-body Stillinger-Weber potential.


The competitive advantage of a destination in relation to other similar destinations should stimulate the commitment of stakeholders on the supply side to encourage more investments and actions in the tourism sector, making it more attractive, competitive and sustainable. The objective of this study is to analyze the competitive position that the tourist destination São Luís occupies in relation to the other capitals of the Brazilian northeast. The study is characterized as descriptive-explanatory, whose universe is composed of 10 destinations in the northeast region of Brazil. The methodology of quantitative nature simultaneously analyzes, in a descriptive and explanatory way, the data regarding the tourist flow and the competitiveness indicators, based on the National Tourism Competitiveness Model. Non-parametric statistical tests were used for comparison and ranking of competitors. The data indicate that the tourist destination São Luís is ranked 6th among the Northeast capitals, both in terms of performance regarding the tourist flow and regional competitiveness. However, it presents a low coefficient of variation along the analyzed period, which indicates a slow and moderate growth, however, positive. The results can contribute to the tourism industry by subsidizing managers in decision making and effective action.

$\frac{{d}^{2}\ensuremath{\sigma}}{d\ensuremath{\Omega}\mathrm{dT}}$ for ${\ensuremath{\pi}}^{+}$ mesons produced in ${\ensuremath{\pi}}^{\ensuremath{-}}p\ensuremath{\rightarrow}{\ensuremath{\pi}}^{\ensuremath{-}}{\ensuremath{\pi}}^{+}n$ was measured at seven incident energies between 203 and 357 MeV and the integrated reaction cross section was calculated. The matrix element, when extrapolated to threshold and compared with soft-pion calculations, determined the chiral-symmetry-breaking parameter $\ensuremath{\xi}=0.05\ifmmode\pm\else\textpm\fi{}0.26$, which is consistent with the Weinberg Lagrangian. The large hard-pion contributions at 203 MeV demonstrated the absolute necessity for comparing at threshold.


Two preceding papers (Crozier and Pincus, 1929-30, a, b) have described the first portion of an at tempt to explore the functional basis for quantitative relations between the average extent of upward orientation by young rats creeping geotropically upon an inclined surface, and the slope of the surface. A fundamental question has to do with the "reality" of equations purporting to describe the connection between the mean angle (0) of oriented path on the surface, during steady progression, and the inclination (~) of the substratum. We have proposed to regard t he treatment of this specific problem as illustrating a procedure which has rather general implications (cf. Crozier, 1929; Pincus and Crozier, 1929), because in an important respect it seeks to deal concretely with the otherwise troublesome matter of variation of response or performance,--and indeed to make use of it in such a way that the observations provide an automatic "internal" check upon the significance of their mean values. In certain genetically stabilized lines of rats it was found that for each such line the reproducible relationship between the angle of oriented progression on a sloping surface (0) and the inclination of the surface (a) could be expressed in terms of convenient quasi-rational coordinates providing graphs sensibly rectilinear, but that the slopes and axis intercepts of these graphs differed in the several races. I t was emphasized that the constants in the equations for such relationships should provide the kinds of heritable, dimensionally significant, units with which an analytical system of genetics must ultimately deal if the mode of action (the "nature") of genes is to be discussed. 201


A study was conducted anticipating vector control for the control of Dengue Haemmoraghic Fever ( Aedes aegypti ), malaria ( Anopheles aconitus ) and filariasis ( Culex quinguefasciatus ) using a local strain of Bacillus thuringiensis H-14 grown in local media (coconut water and soybean infusion). Tryptose Phosphate Broth chemical media (standard media) was used as a comparison to the media under investigation. Good growth was obtained in all media (local media and standard media) and local strain of B. thuringiensis H-14 was effective against the three mosquito larvae. The local strain of Bacillus thuringiensis H-14 cultured in coconut water media, killed 50% of the third instar larvae of Ae. aegypti , An. aconitus and Cx. quinquefasciatus at concentrations of 13 x 10' 5 , 31 x 10 -5 and 10 x 10 -5 concentrations for 24 hours of exposure respectively and 13 x 10 -5 , 9 x 10 -5 and 7 x 10 -5 at 48 hours exposure. Meanwhile when B. thurigiensis H-14 were cultured in soybean infusion media, they killed 50% of the third instar larvae of Ae. aegypti , An. aconitus and Cx. quinquefasciatus at concentrations of 5 x 10 -5 , 7 x 10 -5 and 4 x 10 -5 for 24 hours of exposure respectively and 3 x 10 -5 , 5 x 10 -5 and 3 x 10 -5 at 48 hours exposure. However when they were cultured in TPB media, they killed 50% of the third instar larvae of Ae. aegypti, An. aconitus and Cx. quinquefasciatus at concentrations of 12 x 10 -5 , 15 x 10 -5 and 3 x 10 -5 for 24 hours of exposure respectively and 12 x 10 -5 , 15 x 10 -5 and 2 x 10 -5 at 48 hours exposure. This investigation shows that the local strain of B. thuringiensis H-14 has potential as bioinsecticide agent.


Furthering the established association between environmental influence andfirms' performance, the study tested the mediating role of strategic planning on the connection between dynamic environment and firms' performance. Data for the researchwere collected from 245 manufacturing Small and Medium Enterprises (SMEs) operating in Khyber Pakhtunkhwa (KP), Pakistan through survey questionnaires. Statistical analysis of Confirmatory Factor Analysis (CFA), Path Analysis, and mediation analysis were carried out to test the hypotheses. The hypotheses testing revealed that environmental dynamism strongly influenced firm performance as well as strategic planning. Similarly, firm performance showed significant response to strategic planning. Deeper analysis of mediation confirmed partial mediating role of strategic planning on the association between firms' performance and environmental dynamism. The findings of the research implies that managers should consider business environment in each strategic choice making it alignedwith its strategic planning,firm goals and objectives in order to promote business.


Abstract : This thesis provides a comparative analysis of the financial management curriculum at the Naval Postgraduate School (NPS) and other graduate public financial management curricula offered in graduate college and university programs throughout the United States. MBA curriculum data were solicited from business schools, MPA curriculum data were obtained from policy school and DoD components were polled for service-sponsored graduate education data. Curricular data are compared and evaluated. The thesis concludes that the financial management curriculum at NPS is a special program that includes the best of both MBA and MPA curricula. The NPS curriculum coverage is uniquely adapted to provide public sector graduate financial management education. No other program offered in the U.S. is better designed to meet the financial management education needs of the Navy and Department of Defense. It meets the requirements of the sponsor, and is a course of study that the Navy can depend on to produce financial managers to handle present and future fiscal challenges.


Chapter 5 spotlights Benedictine nuns as intercessors, focusing especially on how they served those who were not members of their communities through offering prayers. This role—both in its idealized forms and in its lived realities—is reconstructed through the conventual and personal seals, charters, letters, mortuary rolls, prayer books, and psalters that women's communities received, produced, and used. This chapter challenges the persistent scholarly assumption that nuns' intercessory prayers depreciated in value over the central Middle Ages because, unlike their male counterparts, they could not offer the individualized forms of commemoration increasingly desired by prospective patrons—namely Masses—without the assistance of resident chaplains or visiting priests. Comparative analysis of the extant documentary sources from religious communities in Oxfordshire reveals that the nuns of Godstow Abbey rivaled neighboring monks, canons, and Templars in attracting lay donations in return for certain spiritual benefits, particularly prayers for the remission of sins and salvation.


Abstract We developed a one-dimensional, time-independent, hydrodynamic model for dusty gas flows in cometary atmospheres that accounts for a broad size distribution and fragmentation of dust. In this model, water vapor is the only constituent of the gas and the grains do not evaporate. The initial gas Mach numbers were obtained as a function of radius of nonfragmenting dust particles of a single size in the range 10 -6 to 10 +1 cm, assuming a mass ratio of dust-to-gas release rates χ = 1. It was found that particles larger than about 1 mm decelerate the initial gas flow very little. The velocities of particles with radii of 10 -6 to 1 cm were also calculated as a function of distance from the nucleus in order to find the acceleration regions for particles of different sizes when a dust size distribution is considered. The continuous dust size distribution was approximated by 21 discrete sizes with a logarithmic scale from 10 -4 to 1 cm in particle radius. The fragmentation model was applied to study the deviation of intensity profiles from the simple 1/ z relationship for dust jets in Comet Halley observed by the Giotto spacecraft, z being the radial distance from the surface of the nucleus. We found that the observed increase of I · z by a factor of 10, where I is the dust intensity, implied that a parent particle must fragment into 10 12 daughter particles within tens of seconds of release from the nucleus to counteract the strong effect of acceleration on the profile. If dust particles fragment in such a short time scale, only micrometer-sized grains are likely to have been measured by Giotto; however, millimeter-sized grains were detected beyond 600 km from the nucleus of Comet Halley. Therefore, fragmentation is not the only physical mechanism for explaining the deviation of the dust intensity profiles. Additional factors such as divergent flows from different parts of an extended surface source region, each part emitting dust into overlapping cones with nearly the same opening angle, are needed to interpret the intensity deviation.


Objective To study the effects of postoperative immune-enhancing enteral nutrition (IEEN)on the liver function and postoperative infectious complications after hepatectomy in patients with hepatocellular carcinoma.Methods Between January 2010 and December 2011,96 patients undergoing hepatectomy for hepatocellular carcinoma were randomized in a double-blind manner to receive postoperative enteral nutrition with IEEN (IEEN group,n =48) or standard enteral nutrition (control group,n =48) for 5 days,respectively.Calorie and nitrogen of the same quantity were provided for both groups from the first day after surgery.The liver function tests and routine blood tests were performed.The postoperative hospital stay and postoperative infectious complications were also compared between these two groups.Results The serum albumin,prealbumin,alanine aminotransferase,and total bilirubin levels had no significant differences between the two groups (all P > 0.05).On the 6th day after operation,the level of total lymphocyte count was significantly higher in the IEEN group than that in the control group [(2106 ± 1057) vs.(1648 ± 1079) / μL,P =0.038).The postoperative hospital stay was (10.3 ±5.6) days in the IEEN group and (13.4 ±6.7) days in the control group (P =0.016).Postoperative infectious complications were observed in 8 (16.7%) patients in the IEEN group and 17 (35.4%) patients in the control group (P =0.036).Conclusion Early postoperative IEEN can improve the clinical outcomes of liver cancer patients after hepatectomy.

Findings on gender and workplace deviance have been mixed and inconclusive; hence, there is a need to further examine gender differences in workplace deviance, especially in Local Governments where employees' deviant behaviours seem to be highly prevalent. Thus, this study examined gender difference in workplace deviance among Local Government employees in Nigeria. Two hundred employees (male = 100; female = 100) were selected from the four Local Government Areas in Akoko Ondo State, Nigeria using a purposive sampling technique. Their ages ranged from 21 to 57 years (M = 35.99; SD = 11.04). The participants responded to Workplace Deviance Scale. Results of the independent t-test revealed that male Local Government employees showed higher tendencies to exhibit workplace deviant behaviours (M = 64.12) than their female counterparts (M = 22.30). Based on this finding, we suggest that more emphasis should be placed on addressing the issue of workplace deviance among male public sector employees than their female counterparts.

To clarify the morphological and phylogenetic differentiation of Bandona boninensis Suzuki 1974 in Chichi-jima Island of the Bonin (Ogasawara) group of Islands, we studied the external morphological characters and performed sequencing of the cytochrome c oxidase subunit I (COI) gene of mitochondrial DNA (mtDNA) and 28S rRNA of nuclear DNA (nrDNA). The sequences of COI and 28S rRNA were identical among the individuals of B. boninensis. These results suggest that B. boninensis experienced a rapid expansion of its distribution in Chichi-jima Island without undergoing any morphological and molecular differentiation.


Acorus calamus Linn. dried rhizome is used as crude drug in traditional Thai medicine. The quality specification of this crude drug was investigated. The rhizomes were collected from 15 different areas throughout Thailand. The macroscopic characters were pale brown with longitudinal furrows and circular, with pitted scars of rootlets, internally whitish and spongy and aromatic odor. The microscopic characterization revealed starch granules, secretory sac containing volatile oil and prismatic crystal of calcium oxalate. The total ash, acid insoluble ash, loss on drying, moisture, ethanol–soluble extractive, water–soluble extractive and volatile oil contents were 4.49 ± 0.15, 0.83 ± 0.07, 12.23 ± 0.34, 13.15 ± 0.46, 7.32 ± 0.29, 9.53 ± 0.45 and 1.37 ± 0.11 % w/w respectively. TLC fingerprints of ethanolic extracts of A. calamus dried rhizomes were demonstrated using silica gel as stationary phase and toluene : ethyl acetate (9:1) as mobile phase. Detection under UV254 and spraying with anisaldehyde sulfuric acid reagent showed the dominant band of asarones. Determination of calamus oil by GC/MS using ZB-5 capillary column showed - and -asarone at 0.26 ± 0.04and 0.12 ± 0.02 mg/µl respectively.


The description of the empirical structure of interbank networks constitutes an important field of study since network theory can be used as a powerful tool to assess the resilience of financial systems and their robustness against failures. On the other hand, the development of reliable models of interbank market structure is relevant as they can be used to analyze systemic risk in the absence of transaction data or to test statistical hypotheses regarding network properties. Based on a detailed data-driven analysis of bank positions (assets and liabilities) taken from the Bankscope database, we here develop a minimal, stochastic, agent-based network model that accounts for the basic topology of interbank networks reported in the literature. The main assumption of our model is that loans between banks attempt to compensate assets and liabilities at each time step, and the model renders networks comparable with those observed in empirical studies. In particular, our model is able to qualitatively reproduce degree distributions, the distribution of the number of transactions, the distribution of exposures, the correlations with nearest-neighbor out-degree, and the clustering coefficient. As our simple model captures the overall structure of empirical networks, it can thus be used as a null model for testing hypotheses relative to other specific properties of interbank networks.


The success of Thermatech (R) technology to Colorbond (R) steel as roofing is undeniable. As discussed on a number of occasions in Building Connection, the incorporated technology improves thermal performance by reflecting more of the heat from the sun. Consequently, this means there is less heat absorption and the subsequent transfer of heat through to the roof space. This 'trapping' of heat in roof and wall spaces makes homes uncomfortable for the occupier and often leads to greater demand on air conditioning units and power bills.

These passages undoubtedly deepen Kant's account of freedom. However, they cannot show that Kant's doctrine of freedom "presents a quite remarkable unity" or is a "coherent and harmonious whole." Camois shows that Kant's position is free of some alleged incoherences: but the overall coherence of the doctrine is not shown. Is freedom Fact or Ideal? If it is only an ideal for the finite, then why must they have this ideal? To show why this ideal is not dispensable we would need to consider the whole critical enterprise, to understand whether and why freedom is a requirement of reason, and grasp how and how far we should expect to explicate the relations between nature and freedom. The claims of coherence remain unestablished so long as the crucial links between freedom and reason are traced back no further than the insistence that there is a fact of reason that is prior to knowing as well as to doing.


The Raman spectrum of yellow Hg2I2 contains features at 110 and 192 cm-l assignable to Hg-Hg stretching and Hg-1 stretching respectively. The spectrum of yellow HgI2 at c. 150o shows bands at 33 cm-1 (I-Hg-1 bending) and 133 cm-1 (Hg-I stretching). The Raman shifts for red HgI2 are 24, 111, and 137 cm-l, attributable to I-Hg-1 bending, symmetric and asymmetric Hg-1 stretching respectively. Assignments are made on the basis of factor group analyses on the Bravais unit cells. Some force constants are calculated.


This paper is mainly summarized the application of ultrasonic techniques of sonochemistry in food industry. Ultrasonic techniques are finding increasing use in food industry for both the analysis and modification of foods. low-intensity ultrasound is a non-destructive technique that provides information about physicochemical properties, such as composition, structure, physical state and rheology properties. High-intensity ultrasound is used to alter, either physically or chemically, the properties of foods, for example to generate emulsions, promote chemical reactions, inhibit enzymes, tenderize meat, modify crystallization processes and promote the extraction of soybean protein.


Inheritance of ear type, shelling habit, awns and grain color in fourteen intra- and inter-specific crosses of tetraploid wheats has been studied. Monogenic and digenic control of ear type and shelling habit was noted except for MACS-10 × 'Chandur', where three pairs of alleles were involved (57:7). In 'Bansi-20-7-3' × 'N-5-67-14', incomplete dominance of awned condition with 1:2:1 segregation was observed. Out of nine combinations, in six crosses there was monogenic control of red grain color. In three combinations the segregation suggested digenic control of this character. Comparison of the genetic behaviour of all these characters revealed constancy in the genetic constitutions of unit character, shifts in segregation ratios in intra- as also inter-specific combinations.


The invention discloses a substrate of a printed circuit board and the printed circuit board. The substrate comprises a metal layer arranged at the top layer and serving as a signal line, a low dielectric constant material layer and FR-4 level glass fiber epoxy resin, wherein the low dielectric constant material layer and the FR-4 level glass fiber epoxy resin are pressed below the metal layer in layers. According to the substrate, multiple different boards are pressed, the thickness of the substrate is reduced through the pressing mode, metal with a low price and FR-4 level boards with a low price are adopted so that the cost of the printed circuit board can be reduced, only one low dielectric constant material layer is arranged, the thickness of a medium is reduced, meanwhile, the capacitance is reduced, and therefore the purposes that the impedance is improved and the manufacturing cost of the printed circuit board is reduced at the same time are achieved. Further, the probability of adjacent layer hollowing is reduced.


Abstract : Plasma drift measured by SABRE in the E-region have been compared with those obtained from HILAT, at an altitude of 800 km. Results are not consistent with perfect mapping of the electric field between the two regions. Furthermore, no field-aligned current signature is observed by SABRE. A comparison of E-region plasma drifts measured by SABRE and F-region scintillations measured by the NNSS satellites suggests that the latter may be related to regions of reduced electric field in the F-region. This is consistent with the presence of field-aligned currents which produce kilometer-scale structure in the F-region plasma. Mean plasma convection patterns in the E-region have been derived as a function of the IMF components By and Bz and the magnetic index Kp. Convection flows are much stronger for southward Bz. The time of the evening convection reversal occurs at later local times for increasingly negative By. As Kp increases radar measurements occur during a higher proportion of the day and the evening convection reversal also moves to earlier local times. Keywords: Auroral backscatter; Irregularities; Convection; Aspect angle attenuation.


The use of renewable energy is causing changes in the energy field, among which wind and water energy power generation technologies have developed rapidly. In the new power system with new energy as the main character, energy storage will be needed to assume the role of peak shaving and valley filling, voltage regulation and frequency regulation in the power system. At present, most energy storage power stations operate in an exclusive manner, resulting in low energy storage utilization. Based on the concept of resource sharing, considering the economics and feasibility of shared energy storage system with new energy characteristics, first analyze the complementary and controllable capabilities of energy storage that promote new energy consumption, and then study the multiple energy storage sharing mechanism that promotes new energy consumption Finally, a coordinated regulation strategy for shared energy storage system that takes into account reducing wind curtailment and smoothing output is proposed to provide customers.


This study identified which combination of background factors, work practice, and psychosocial variables could discriminate most accurately between individuals with mild, moderate, or severe musculoskeletal discomfort in a population of 155 customer service representatives of a telecommunications company. These risk profiles were obtained for overall upper body musculoskeletal discomfort, as well as for each individual body part (neck, shoulder, elbow, wrist/hand, and back). Results of discriminant analyses suggested that risk profiles were different for each body part and could accurately classify from between 50 and 100% of the individuals into mild, moderate, or severe discomfort categories. These risk profiles were all highly significant ( < 0.01). This research identified the amount of social support, job variety, and skill utilization on the job as the psychosocial variables most often associated with musculoskeletal discomfort in this population.

[JDEM-Omega is one of the three concepts that contributed to the Wide-Field Infrared Survey Telescope (WFIRST) mission advocated by the Astro2010 Decadal Survey. It is the concept on which the recommended observatory configuration is based.] The Joint Dark Energy Mission (JDEM) is a space-based observatory designed to perform precision measurements of the nature of dark energy in the Universe. It will make an order of magnitude progress in measuring the equation of state parameters of the Universe of most importance for understanding dark energy. JDEM-Omega is a wide-field space telescope operating in the near infrared. Dark energy measurements will be made via large surveys of galaxies and supernova monitoring. These will be an order of magnitude larger surveys than currently available and will provide enormous catalogs of astrophysical objects for many communities ranging from solar system to galaxy to galaxies/clusters to cosmology. JDEM-Omega is a mission concept collaboratively developed by NASA and the Department of Energy, with substantial input from the JDEM Science Coordination Group and community at large.


Abstract In this study, an investigation was carried out in order to determine the effect of annealing temperature on the mechanical properties of H13 steel. Heat treatments were applied on samples at different temperatures in both, the as-received and as-quenched conditions. In order to indicate the effect of heat treatment temperature, hardness measurements and tensile tests were performed at all chosen temperatures. At relatively high temperatures the mechanical properties of the H13 steel have been diminished considerably.


Testicular cancer is the most common solid organ malignancy affecting males between 15 and 35 years of age with an annual incidence of approximately 9300 in the United States.1 Germ cell tumors (GCTs) are the most common type of testicular cancer and are broadly categorized as seminomatous (SGCTs) and nonseminomatous germ cell tumors (NSGCTs). Therapeutic advances and utmost sensitivity to cisplatinbased combination chemotherapy make it one of the most curable solid neoplasms, even in the presence of metastatic disease with a 5year survival rate of approximately 95%.1 The standard chemotherapy regimen of bleomycin, etoposide, and cisplatin (BEP) cures a significant proportion of patients. However, despite these advances, a subset of patients have refractory disease or develop disease recurrence requiring salvage chemotherapy. Salvage chemotherapy options include conventionaldose chemotherapy (CDCT) with cisplatin and ifosfamide plus paclitaxel (TIP) or vinblastine (VeIP) or etoposide (VIP), or highdose chemotherapy with autologous hematopoietic stem cell transplantation (HDCT/HSCT).2-4 HDCT with HSCT has been available as a therapeutic option since 1986 and has provided cure to selected patients even as a third line regimen.5 We provide data for and our approach to the utilization of HDCT with HSCT in advanced GCTs.

planning methods have been made but they don't have
 any significance. The point is that a office
 interior planning methods must be applied in
accordance with the characteristics of a organization
 which office building accomodates. In this study,
organizations of renters are classified into 4 kinds
 according to Bureaucray level and Interaction level.
 And 4 types of office interior planning methods are
listed. Organization live clerical work requires
large undivided space, so open planning type is
suitable, single room type is adequete for ekecutives
 and group space is good for research group, office
 landscape is appropriate for design team. Whether
any planning methods are used, commonly required
space must be furnished and merits of other methods
can be used for a better planning. As the society
 becomes more complex and various than before, new
concept of office interior space are being turned
out.


WHO AM I? Why am I here?" So went Vice Admiral James Stockdale's surprisingly exis tential outburst in his slightly more than fifteen minutes of fame as a vice presidential candidate. But the com ment could just as easily have issued from the entire nation, which was suffering last year from a collective identity crisis. With the Cold War over, the United States had become unsure of its place in the world. And its two major industrial ized partners, Europe and Japan, were both suffering from a loss of purpose as well. The result was a year of confusion and drift in the management of the international economy. The numbers were bad enough. Economic growth in the industrialized countries crept ahead at a sluggish 1.5 percent pace in 1992?not enough to keep unemployment from rising. The jobless rate in the countries of the Organization for Economic Cooperation and Development averaged 7.9 per cent over the year and was projected to creep up to 8.2 per cent in 1993. But the debilitating problem was less one of production than of psychology. In the United States, in particular, the mood was extraordinarily sour, as Americans developed a gloomy foreboding, not seen since World War II, that their nation was caught up in an inexorable process of economic decline and that their children's generation would not live as well as they had.


Circular dichroism (CD) is known to be a very sensitive probe of the conformation of molecules and biomolecules. It is therefore tempting to implement CD in a pump-probe experiment in order to measure ultrarapid conformational changes which occur in photochemical processes. We present two technical developments of such time-resolved CD experiments. The first one relies on the modulation of the probe polarization from left to right circular whereas the second one measures the pump-induced ellipticity of the probe with a Babinet-Soleil compensator. Some applications are described and extension of these techniques towards the study of elementary protein folding processes is discussed.


Considering the above, the construction of an optimal model structure for any experiment may include the representation of the model as a channel for transmitting information from the observed phenomenon to between the object of study and the developer (Menin, 2022). At the same time, in the modeling process (thinking act) it is assumed that the observed phenomenon is not subjected to external disturbances. Therefore, instead of the term "observer" or "experimentator", who studies the object through measuring instruments, in what follows we must use the term "thinker."

Latin American countries, especially those placed in the Pacific shore; have a good growth vector based in macroeconomic parameters like GDP, activity rates and foreign investment. At the same time, these elements evolve in parallel with the trade activity, both as for imports/exports amounts and for containership ports throughput (measured in TEUs).This paper shows the evolution of these parameters along the last decade, and also performs a multivariate analysis, based on panel data methodologies, in order to put all these variables into relation.The results show the relevance of this geographical area as a key growth vector with respect to all the Latin American aggregate, and also show the positive relation between activity rates and innovation, TEUs throughput, and a slightly negative contribution of foreign direct investment and employment in those countries.


In the age of globalization and international competitiveness, teacher education (TE) emerges as a national necessity in governments' attempts to promote "knowledge societies" (p. 1). The primary impetus behind International Research, Policy and Practice in Teacher Education: Insider Perspectives, edited by Jean Murray, Anja Swennen, and Clare Kosnik, is to deepen our understanding of how teacher educators' perspectives as insiders could make changes in policy, research, and practice. In addition to an Afterword chapter, the volume amalgamates 13 chapters written by twenty-five authors. In the Preface, A. Lin Goodwin brings into light the inconsistencies, quick sands, and anxieties that teacher educators (TEds) have to live by. For example, even after joining academia, TE is still regarded "as a field without a knowledge base" (p. v). Despite the close inspection over their job, TEds do not totally submit to the policy makers' directives. For Goodwin, this collection comes at an opportune moment when the world is witnessing a "global reform movement" (p. vi).


Thirty seven patients with resectable peritoneal dissemination that were curability B in colorectal cancer were analyzed clinically and assessed factors which influence the survival. The 5-year survival rate was 31.4% and according to the multivariate analysis, there were two prognosis regulating factors included the number of disseminations of 3 and fewer and lymph node metastasis of n2 and under. Patients possess above two factors have good prognosis (survival at 5 years=56.8%). Based on prior statistical analysis. P1 and P2 divided into two groups according to the number of disseminations of 3 and fewer or 4 and over respectively. There were no statistical difference in two groups in P1. But in P2, three and fewer group had a statistically superior survival than 4 and over. And there were no statistical difference between 3 and fewer group of P2 and all of P1. These results suggest that it is appropriate that disseminations to the remole peritoneum of 3 and fewer are included P1 and 4 and over are included P2.


Blocking conditions in the Gulf of Alaska region prevailed throughout  January 1957. The consequences of that aberration will be emphasized, but first. it will be shown how this tenacious feat'ure fitt'ed into the general circulation. Figure 1 is the 700-mb. 30-day mean chart for January 1957. The  hemispheric irculation consisted of three full-latitude troughs located along the east coasts of Asia and North America and near the Ural Mountains. The pattern would have been rather symmetrical had there been a fourth full-latitude trough in the eastern Pacific Ocean. Instead, the flow in that area was distorted by two low-latitude troughs with a short wavelengt'h, separated by a ridge of great amplit'ude. The southern portion of the eastern Pacific ridge was located in an area in which a ridge occurs on the normal map for January [13]. However, that portion of the ridge in the  Gulf of Alaska wa,s highly anomaIous.  On the normal 700-mb. chart  for  January, cyclonic curvature characterizes the latter region; but in January 1957 the curvature was markedly  anticyclonic,  and  the  contour heights were far above normal. The dotted lines in figure 1 represent the height departures  from normal  (hereinafter called DN). The large magnitude (+720 ft.) and extent of the height DN near Alaska overshadowed all ot'her centers in t,he Northern Hemisphere. This DN center apparently started in the eastern Pacific as a small positive height anomaly early in the month. Meanwhile,, the Siberian block of December 1956 investigated by Green [2] relaxed, and its associated positive height DN progressed to eastern Siberia. Thereafter, at least a portion of this DN appears to have amalgamated with and reinforced the mushrooming anomaly of the eastern Pacific. Another indication of the anomalous flow in the eastern Pacific is given by the monthly mean isotach chart (fig. 2). Not only were 700-mb. wind speeds in this area very weak, but also the belt of maximum westerlies was split int'o two


This paper presents statistical models that analyze crosssectional data related to student attainment in Eng lish and Maltese spelling. For each spelling test a random sa ple of 2040 students, whose age ranged from 6.5 to 16 y ears, was selected to examine the progression of spelling skills over time. The sample comprised equal numbers of m ale and female students attending state, church and pri vate schools to investigate gender and school bias in st udents' spelling abilities. This hierarchical nested data can be deemed as a type of two-level data, in which the st udents spelling scores are level-1 units and schools are t he level2 units. This multilevel approach provides an adeq uate framework for modelling hierarchical data at severa l levels of nesting. To inspect the effect of age on student performance in English and Maltese spelling in diff erent schools, a random coefficient model is fitted. This allows the school-specific coefficients describing individ ual trajectories to vary randomly when the spelling sco res are regressed against the student age. 1. DATA COLLECTION To examine the progression of spelling skills of Ma ltese students in primary and secondary schools, twenty a ge cohorts (61⁄2, 7, 71⁄2 ... 15, 151⁄2, 16) were identified. All students, who at the time of the test administratio n were two weeks younger or two weeks older than any of th e specified ages, were included in the study. Moreov er the selected students were also stratified by gender an d school type to guarantee a representative sample. T o ensure sufficiently large numbers of participants a nd proportionate allocations of students in each age g roup, it was decided that each cohort should include 60 pupi ls from state schools, 24 students from church schools and 18 pupils from private schools with an equal balanc e of boys and girls within each group. Maltese secondary state schools are classified as J unior Lyceums, which take in students who pass the 11+ ex ams and Area secondary schools, which take in students who fail these exams. To ensure a proportionate allocat i n of participants, 30 students from Junior Lyceums, 30 p upils from Area Secondary, 24 students from church school s and 18 pupils from private schools were selected wi th equal numbers of boys and girls within each cohort. Each of the twenty age groups comprised 102 students mak ing an overall total of 2040 participants for each test . The ages of all participants fell within a four week ti me window centred on the chronological age assessed. The Maltese and English spelling manual compiled by (Camilleri, Firman, Martinelli 2010) was used to me asure spelling skills of school children. To reduce disr uptions each test, which consists of a list of 87 words ran ked by order of difficulty, was administered to whole clas se rather than selecting the few students from each cl ass who fitted the 4-week age window. A sample of approximately 12,000 participants was collected for each test to get the required number of the 2040 student s that fall within the required age cohorts. This sample amounted to about 20% of the whole school populatio n in 2009 and guaranteed a maximum margin of error of around 2%. Schools were selected from all the six districts of the Maltese islands to ensure a good geographical representation. For both spelling test s the students were asked to provide the name of school, gender, age and date of birth. This information wa s essential to identify the students who would fall w ithin the four week time window of each specified age and the type of school s/he attended. After finalizing dat a collection the scripts were sorted by date of birth . All students who satisfied the stipulated 4-week window criterion were included in the survey sample. The selected scripts were then corrected and marked, wh ere spelling scores ranged from 0 to 87. Scripts that did not provide the required information were excluded. 2. PRELIMINARY ANALYSIS One of the aims of the study is to inspect and eval uate the progression of spelling attainment with age and com pare the spelling scores between male and female student s attending different school types. Figure 1 displays that females tend to attain highe r scores in English spelling compared to males. This differ ence becomes more conspicuous with age. Another interest ing fact is that English spelling scores increase more rapidly during primary than secondary school years. Figure 1: Mean English spelling scores categorized by age and gender Figure 2 displays a similar attainment in English s pelling of primary school children attending private and ch ur schools. However, achievement in English spelling of primary students attending state schools is poorer. At the age of 6 the disparity in the mean spelling scores is small; however, it becomes more evident with age. Figure 2: Mean English spelling scores of primary pupils categorized by age and school type Figure 3 shows that increments in English spelling scores of secondary pupils are linear and less steep than those of primary students. An obvious fact is that attainmen t of Area secondary students in English spelling is infe r or to their counterparts attending other schools. These s tudents failed the 11+ examinations. Figure 3: Mean English spelling scores of secondary students categorized by age and school type Figure 4 displays similar patterns as Figure 1. Gi rls tend to outperform boys in Maltese spelling at almost al l ages and discrepancies in spelling abilities increase wi th age. The stepwise, rather than linear, increase in the s pelling scores is explained by the fact that 71⁄2 year old st u ents are one year ahead academically than 7-year old pup ils. Figure 4: Mean Maltese spelling scores categorized by age and gender Figure 5 exhibits a contrasting pattern to Figure 2 . Pupils attending primary state schools perform better in M altese spelling but worse in English. This is partly attri buted to the fact that church/private schools assign more ti m for English than Maltese; moreover, pupils are encourag ed to speak in English during school hours. Figure 5: Mean Maltese spelling scores of primary pupils categorized by school type and gender Figure 6 shows similar trends as Figure 3. Increme nts in Maltese spelling scores of secondary students are l inear and less sharp than those of primary pupils. Differ ences in Maltese spelling attainment are conspicuous betw e n schools. Pupils attending Junior Lyceums tend to do best, followed by church, private and area secondary scho ols.

A MULTILEVEL MODEL Generalized linear mixed models are linear in the parameters and the predictors involve a mix of fixe d and random effects. Linear mixed models for Normal responses can be written in the form: = + + y Xβ Zη ε (1) y is a vector of responses; whereas, X, Z are design matrices. β are fixed effects, and η and ε are random effects both assumed to be independent and Normally distributed. ( ) ~ , N ε 0 Σ and ( ) ~ , N η 0 Ψ (2) Xβ is the fixed component and Zη is the random part of the model. Traditional linear regression models are special cases of linear mixed models with Z = 0 . One of the assumptions of linear regression models is that the responses i y are independent. This assumption is not realistic, particularly when observations are neste d within hierarchical structures or are repeated measurement s in a longitudinal study. Multilevel modeling is an alte rnative approach that facilitates the analysis of hierarchi cal data particularly when observations are nested within hi gher levels of classification. A two-level linear mixed model can be written in the form:


Recently, the researches of social robots and agents that smoothly communicate to human are paid to attention. The conventional researches seem to have aimed at the achievement of the society in the meaning of the wide sense. In a word, it is an approach where the designer embedded social competence like human. In this paper, we propose model-based multi user learning agent (M-MULA) to interact with various types of people effectively towards realization of social interaction. M-MULA is equipped with two functions for social learning. One is direct learning function by individualizing of user parameters, and another is indirect learning function based on past experience and the similarity between each users. We confirm proposed method in computer simulation to evaluate the effectiveness


Hypercholesterolemia is one of the major risk facto rs that precipitate coronary heart disease and atherosclerosis. abnorma l lipid metabolism is a main cause of dyslipidemia, which is a major risk f actor for cardiovascular disease, obesity, cholestasis, and overall mortalit y. It is well known that diet plays an important role in the control of cholester ol homeostasis . Many studies reported that flaxseed may have protective effect against diseases like cardiovascular diseases CVD, reducing the risk of cancers, reducing the incident and progress of diabetes .High omega-6/ome ga-3 ratio intake promotes development of many chronic diseases like cardiovascular disease, cancer, inflammatory and autoimoune disease, rheuma toid rthritis, asthma. Accordingly, the purpose of the present study was t o investigate the effect of flaxseed and flaxseed oil against high choleste rol diet induced hypercholesterolemia in rats by adjusting ω6 :ω3ratio(2.5:1),.

Imaging and signal processing technologies play a critical role in many medical diagnoses. However, these tools have not yet been utilized to aid in the clinical diagnosis or treatment of neurocognitive disorders such as Attention Deficit Hyperactivity Disorder (ADHD). This paper reviews research literature investigating the potential ADHD diagnosis and treatment efficacy of various imaging and signal processing modalities. The benefits and drawbacks of each modality are then summarized and compared by a decision matrix wherein the viability of a computer vision modality is highlighted. Finally, the paper suggests a general system design for a modality that uses computer vision and that can be used along with neuropsychological assessments for the diagnosis and treatment of ADHD.


In order to solve the beacon point detection and matching problem in unmanned aerial vehicle( UAV) probe and drogue refueling, a near-infrared beacon detection system was designed, and a robust beacon point matching algorithm was proposed. The near-infrared beacon detection system was constituted with eight 850 nm wavelength near-infrared Light-Emitting Diode( LED) lights arranged uniformly in outer ring of the refueling drogue, and 850 nm band-pass filter integrated with Logitech C310 camera. To solve the mismatch problem caused by interference points, a beacon point matching algorithm based on geometric feature constraint was presented, which can accomplish the far interference point exclusion, feature point sorting, near interference point exclusion and feature point marking. The algorithm performance was validated through experiments in various complex environments. The results show that the beacon detection system has the advantages of high detection accuracy and reliability, and the beacon point matching algorithm can realize exact matching of beacon points robustly in various complex environments. Experimental results of relative position calculation show that the calculation is of high accuracy.

Abstract The GERmanium Detector Array ( Gerda ) experimentattheGranSassoundergroundlaboratory(LNGS) of INFN is searching for neutrinoless double beta (0 νββ ) decay of 76 Ge. The signature of the signal is a monoenergetic peak at 2039 keV, the Q ββ value of the oped to describe the observed energy spectrum. The model contains several contributions, that are expected on the basis of material screening or that are established by the observation of characteristic structures in the energy spectrum. The model predicts a flat energy spectrum for the blinding window around Q ββ with a background index ranging from 17.6 to 23.8 × 10 − 3 cts/(keV kg yr). A part of the data not considered before has been used to test if the predictions of the background model are consistent. The observed number of events in this energy region is consistent with the background model. The background at Q ββ is dominated by close sources, mainly due to 42 K, 214 Bi, 228 Th, 60 Co and α emitting isotopes from the 226 Ra decay chain. The individual fractions depend on the assumed locations of the contaminants. It is shown, that after removal of the known γ peaks, the energy spectrum can be fitted in an energy range of 200 keV around Q ββ with a constant background. This gives a background index consistent with the full model and uncertainties of the same size.


What follows in these pages is an attempt on my par t to formulate some of the most important ideas that I have been slowly develo ping for myself, through all my reading and all my teaching. Quite possibly ther e is much here that will not seen valid to others. But it is all valid for me. I find in practice that no critical standards mean anything to me except those which I myself have worked out. I have no reason to suppose that I am singular in thi s. Therefore I plan to use this book, not at all to force my ideas upon others, but simply to make them aware that there is such a thing as critical theory in the wor ld, and if possible to set them to work constructing one for themselves. Whether this theory finally agrees with mine or not, is of very little importance. As Gamal iel Bradford has observed, what people think "is of little consequence, provided on e has taken even a little step in the enormous task of making them think at all."


Three main issues relating to the question of silent speech in reading are addressed: 1) How do Chinese speakers process Chinese ideographs in short-term memory? 2) How is Chinese students' learning of written English affected by the transition to an alphabetic language? 3) Are the strategies for encoding written words in short-term memory different for students of diverse language background? Chinese and Spanish bilingual students were tested for short-term memory encoding strategies on word-recognition tests. Chinese speakers were found to encode Chinese ideographs phonologically, but both Chinese and Spanish learners of English were found to encode English words visually. Implications for the acquisition of reading are discussed in terms of a two-stage model.

The recombination parameters of aluminium–oxygen complexes in silicon have been reassessed by applying lifetime spectroscopy on several n‐ and p‐type intentionally Al‐contaminated and control samples, using a single‐level defect model. The presence of the control samples has allowed greater accuracy for the extraction of the recombination lifetime. The uncertainty ranges of the parameters have been tightened significantly by simultaneously fitting the lifetime on several samples. The electron/hole capture cross section ratio k was reassessed to be 380, in the uncertainty range of 330–460. A direct comparison of the n‐ and p‐type samples has shown that those complexes are much more recombination‐active in p‐type silicon than in n‐type silicon at low and intermediate injection levels.

Setting and scope Student involvement in course direction, in a large, first-year Management Information Systems course, is the subject of this paper. Student involvement is in harmony with the student-centred ambitions of the course that had its genesis in the late 80's, motivated by a building disquiet with the atmosphere and outcomes of teaching/ learning in a traditional setting. This disquiet is now well recognized in the literature (Boud, 1988).


Abstract : Procedural semantics models have diminished the distinction between data structures and procedures in computer simulations of human intelligence. This development has theoretical consequences for models of cognition. One type of procedural semantics model, called schema theory, is presented, and a variety of cognitive processes are explained in terms of the theory. In schema theory, the flow of processing control is determined not by a central monitor, but by interactions among the conceptual entities (schemata) that make up the model. Intelligence is distributed in this model. Schemata interact by providing activation resources to each other. Instantiation is the special process whereby a partial copy of a strongly activated schema is created. In this copy, the variables of the schema are filled with particular values. Such copies make up specific or episodic memory. The schemata on which they are based comprise generic or semantic memory. Many of the phenomena of consciousness and of short- term and long-term memory are explained on the basis of the activation processes of schema theory. Unactivated schemata are equivalent to all the unconscious knowledge in a person's long-term memory. Three dimensions for distinguishing or comparing schemata are proposed; function, abstractness, and scope. The contrasts between multi-store models of cognition and schema theory are summarized.


The turtles skeleton plan is an evolutionary developmental novelty in connection with the formation of a tortoise-specific carapacial ridge, which induces the growth of ribs in the dorsal direction and the subsequent formation of several carapace plates. The bone plates of these reptiles have different histogenesis: the neural and costal plates develop according to the mechanism of indirect osteogenesis by perichondral ossification of the axial skeleton elements (vertebrae and ribs), the peripheral and plastron bones develop according to the mechanism of direct osteogenesis in the dermis of the skin - these are the so-called «skin bones», which are derived from individual osteogenic cells outside the axial skeleton and develop by intramembranous osteogenesis. An experiment was carried out to study the post-traumatic osteogenesis of the carapace bone plates on a freshwater turtles Trachemys scripta at the age of 3 months. Two defects of carapace costal plates with a diameter of 4 mm and a depth to the fascia were performed with further routine histological examination. It was found that already on the 90th day the turtles carapace bones were restored with the formation of a full-fledged bone regenerate by the mechanism of indirect osteogenesis.


In 3rd generation image intensifier, Al2O3 film on the input of MCP is a serious influence factor on device MTF due to its electron scattering process. There are no reportes about how to measure the MTF of Al2O3 film. In this paper a new Half-film comparssion test method is creatively established for determing the film MTF, which overcomes the difficulty of measuring super thin film less than a few nm. In this way, the MTF curves of 10nm Al2O3 film can be accurately obtained. The measurement results show that 10nm Al2O3 film obviously decay the MTF performance of the 3rd generation image intensifier and take an important role in the improvement work of 3rd generation image intensifier MTF and resolution performances.

It is proved that in a free nilpotent Lie algebra there are no nonabelian ideals which are free nilpotent as subalgebras. It is also shown that, for any proper ideal S of a free Lie algebra F, the quotient of the lower central terms Fm/Sm is not finitely generated when F = F2 + S. If F = F2 + S, F/S is finite-dimensional and S is finitely generated as an ideal in F, then Fn,/Sn, is finitely generated as an algebra for all mn > 1.

Background/Aims: National guidelines recommend that patients with bronchiectasis should be reviewed by specialist physiotherapists (Polverino et al , 2017) These appointments should involve teaching of individualised airway clearance techniques, promotion of exercise and education to optimise self-management During the covid pandemic, face to face appointments were cancelled Ways of conducting effective physiotherapy consultations remotely were required We used telephone and video respiratory physiotherapy consultations We assessed patient satisfaction with remote consultations and views on future modes of clinic delivery Methods: All patients contacted for a predetermined physiotherapy clinic between 21/4/20 and 29/6/20 were asked questions regarding their consultation and preferences (Table 1) Telephone and video calls were carried out by PM Data was collected via follow up phone calls using a pre-selected questionnaire or postal questionnaire Data was recorded and analysed using Excel plus thematic analysis for free text responses Results: Thirty telephone and 35 virtual consultations were offered 12 virtual consultations were converted to telephone due to lack of internet access Thirty-nine (60%) were new referrals, 26 (40%) were reviews Median age was 65 (range 21-91) Median telephone call duration was 29 minutes (range 15-40) Beyond covid-19 restrictions, twenty-four (37%) preferred a virtual appointment;twenty-two (34%) telephone, four (6%) face to face consultation and fifteen (23%) had no preference Conclusions: The majority of respondents (97%) were satisfied with remote consultation during covid restrictions Interestingly, only 6% preferred to return to face to face (Table presented) appointments Qualitative exploration of reasoning behind these decisions revealed two main themes: convenience and practicality and medical reasons and beliefs In our cohort, 71% of patients preferred to continue remote physiotherapy clinics Individual preferences on format and location of care are key components of NHS plans Our data show that patient satisfaction can be maintained with remote delivery of respiratory physiotherapy, yet more work is needed to standardise and improve remote physiotherapy interventions In addition to patient preference, ascertaining the comparative clinical effectiveness of appointment formats in the longer term will facilitate evidence-based provision of physiotherapy resources


Accurate determination of wall shear stress and heat and mass transfer rates under an impinging jet requires careful analysis of the boundary layer at the impingement surface due to the large pressure gradients near the stagnation point. Modeling the inviscid flow just outside the boundary layer provides the boundary conditions necessary for such an analysis. Previous inviscid models have considered only a small subset of possible jet velocity profiles and with limited spatial resolution. In the present work, analytical solutions to the stream-vorticity equation for two-dimensional and axisymmetric impingement flow with arbitrary velocity profile are found in terms of a surface integral involving the vorticity function, allowing an iterative determination of the stream function throughout the impingement region. Surface pressure distributions and streamline plots are calculated for various impinging jet configurations, including plane, round, and annular jet nozzles. The calculations show excellent agreement with previous experimental and numerical results, while requiring relatively short computation times. Flow predictions are also made for impinging jet configurations for which no previous data or calculations exist.


Recent guidelines for the management of asthma now emphasise the importance of anticipating what lies ahead. The concept of "future risk" has been introduced into our clinical terminology 1. While it may be argued that clinicians have always intuitively paid attention to ideas of future risk as well as future benefit, it is only recently that these have been articulated. Future risk refers to the risk of adverse outcomes such as exacerbations, poor asthma control, accelerated decline in lung function or side-effects of treatment in the near or distant future 2. Similarly, although anticipating future benefit may seem easy, it is not: the response to most asthma treatments is heterogeneous, and predicting those who are likely to benefit from a therapeutic intervention is possible in only a proportion of patients. This is particularly true for anti-inflammatory treatment 3, 4, and many clinicians prescribe empirically.

In asthma studies, the effect of an intervention on some future risks ( e.g. exacerbations) may be measured directly, or inferences may be drawn from measuring physiological variables or biomarkers. The latter are of increasing importance because the future benefits and risks associated with treatment intervention may be related to control of the underlying disease process, as reflected in biomarker levels. For asthma exacerbations, we can assess future risk in three ways. Firstly, we can identify epidemiological factors that characterise the "at risk" patient, e.g. male sex, ethnicity, smoking history 5. Second, there is the patient's individual history. The past is a good predictor of the future. …


A field experiment was conducted at farmer's field under on farm trial during 2011-12, in Jorhat district of Assam, to study the impact of post shooting application of urea and sulphate of potash on the improvement of bunch weight of banana cultivar Borjahaji. The denavelled distal stalk end of the bunch was fed with urea, sulphate of potash blended with fresh cowdung soon after the fruit set. The results showed that when the bunch was fed with urea (7.5g), sulphate of potash (7.5g) blended with 500 g fresh cowdung (T 4 ) all the yield attributing characters viz. , length of fingers, weight of fingers of first hand, weight of fingers of last hand, girth of fingers, weight of first hand, weight of last hand and bunch weight were maximum as compared to denavelling and application of cowdung only (T 2 ) and application of urea and cowdung at denavelled distal stalk end (T 3 ). The minimum of all these characters and bunch weight were obtained in control (T 1 ) where male bud was retained till harvest. The results revealed that the nutrients moved from the blend into the bunch and significantly enhanced the weight of fruits and bunch. When the bunch was fed with urea 7.5 g, sulphate of potash 7.5 g blended with cowdung 500 g (T 4 ) the response was 34.77 per cent, 11 per cent and 5.9 per cent increase in weight of bunch over the treatments T 1 , T 2 and T 3 , respectively.

Based on the man-made wetland systems simulated with Phragmites communis,Zizania caduciflora and Typha latifolia respectively,the comparison study on the effects from the hydrophytes in wetland is made herein.The study shows that(1)the simulated wetland system has a higher effect on de-nitrogen,however,the rate of de-nitrogen varies with the different hydrophytes;(2)the removal of ammonium nitrogen and nitrate nitrogen is an important factor to affect the rate of de-nitrogen,in which the removal of ammonium nitrogen places a dominant role;(3)the root structure of Phragmites communis can increase the content of dissolved oxygen and then improve the living environment of various animals and microbes in the water;(4)the hydrophyte absorption in the wetland is not the major way for the de-nitrogen,but it can directly or indirectly affect both the conversion of different nitrogen forms and the process of the microbial reactions of nitrification and de-nitrification.


Ground anchoring method is composed of anchor headed, tensioning part, and anchorage consist, which is one of retaining wall support method to settle on soil structure. Existed box-type anchor brackets can be wrecked easily because concentration force by eccentric load induced fixed loading plate of anchor brackets. In this study, new bracket system is proposed to overcome the weakness of conventional box type bracket. The new bracket subjected to eccentric load is analyzed with ANSYS Workbench program. As a result, it is shown that this bracket shows steady state with no sudden collapse under 20% eccentricity load in loading plate. Futhermore, the strength is increased about 14% than box-type bracket.


Background: There is a lack of consensus regarding the best option for the treatment of acute Achilles tendon rupture. Treatment can be broadly classified as operative (open or percutaneous) or nonoperative (casting or functional bracing). Postoperative splinting can be performed with a rigid cast (proximal or distal to the knee) or a more mobile functional brace. The aim of this meta-analysis was to identify and summarize the evidence from randomized, controlled trials on the effectiveness of different interventions for the treatment of acute Achilles tendon ruptures.


Equations of motion of large N quantum mechanics are solved for infinite N in the case of unbroken global O(N) symmetry. It is shown that the only correction to the action is a change in the potential. All characteristics of the motion (frequencies of oscillations, times of rolling, a phase portrait etc.) can be computed by means of a classical mechanics for the corrected potential. In particular, a tunneling in the system is absent.


Abstract South Africa Indians come from a variety of linguistic cind cultural backgrounds. Although most South African Indians have adopted English as their mother tongue, their variety of English tends to deviote from Standard English. In this paper a number of common errors of South African Indian secondary school pupils are presented and reasons for these errors are discussed.


By interacting with the environment through trial and error, a deep reinforcement learning (DRL) -based controller is able to learn the patterns underlying a highly dynamic environment, paving the way for self-optimized decision making. Leveraging this capability, we propose a Deep Q-learning (DQL) -based algorithm to perform joint service function chain (SFC) integration and routing tasks for service requests, each with specific stringent end-to-end delay and bandwidth constraints in a cloud-based distributed Network Function Virtualization (NFV).Our design goal is to maximize the number of dynamically provisioned service requests in the network over a time horizon, thus indirectly contributing to maximizing network throughput.Numerical results show that the trained DQL-based algorithm achieves over 95% of the average request acceptance rate and over 96% of the offered load. This performance result is comparable to that of a Resource-Constrained Shortest Path algorithm while achieving a much shorter execution time, approximately 10 times faster.


Introduction: Chronic obstructive pulmonary disease (COPD) patients are at higher risk for pulmonary embolism (PE) due to limited mobility, smoking, inflammation or comorbidities. High D-dimer levels have been detected in many diseases including COPD exacerbation, even in the absence of detectable PE. Aims and Objectives: To determine the optimal D-dimer cutoff value for the diagnosis of PE, in patients hospitalized for COPD exacerbation. Methods: We retrospectively analyzed 180 consecutive patients, admitted to "KAA" and 5 th Respiratory Clinic of Athens Chest Hospital "Sotiria" for COPD exacerbation, according to Anthonisen criteria, during 2014. Fifty from the above patients were found to have been investigated with computed tomography angiography despite a low probability for PE (Wells score). All 50 patients had D-Dimer levels measured as well. Receiver operating characteristic (ROC) curve analysis was used to determine the accuracy of D-dimer measurements in diagnosing PE. Results: Fifty patients (72.1±12.0 years old) were included in the analysis. PE was detected in 10 patients (20%). D-dimer levels of COPD patients with PE (median value: 7655 mcg/L) were significantly higher than those of the patients without PE (median value: 940 mcg/L)(p Conclusions: Patients hospitalized for COPD exacerbation with low clinical probability for PE present D-dimer levels higher than normal, even without PE. The D-dimer cutoff value used to exclude PE should be adjusted, thus reducing the unnecessary use of diagnostic procedures.


Tissue engineering is an enchanting way of producing living tissues for patients who have lost an important tissue or part of it. It forms an excellent and engrossing alternative for maxillofacial reconstruction in near future. The aim of tissue engineering is to regenerate new tissues within a specific environment with help of cells, scaffold, and the signaling molecules(growth factors). Even though MSCs along with bone grafts and BMPs like growth factors forms the ideal triad of TE, various sources were available for these triads. Recombinant protein therapy, cell based therapy and gene therapy are the different approaches used in tissue engineering. A lot of options like vascularized and non vascularized flaps are available for maxillofacial reconstruction. But its shortcomings enables the tissue engineered constructs to be used as a good alternative for reconstruction with improved functional and therapeutic outcome. Today, the field of tissue engineering has expanded tremendously. New technologies like recombinant gene transfer, bioreactors, rapid prototyping etc were on the way of development in the field of tissue engineering, which may help to find out a final solution for the challenges faced during the process of tissue regeneration.


An alternative to the lecture format for teaching junior and senior level material is outlined. The basis of this alternative is the widely used Keller plan which features self-pacing, personal attention for each student, and emphasis on mastery of specific learning objectives. To meet needs particular to upperclass students and to create a learning atmosphere more appropriate for "pre-professionals," we have added the following features: (1) student freedom in selecting his own procedure (textbook readings, exercises, etc.) for mastering the course material, and (2) some variety in topics studied by each individual student. Two successful trials of this adapted Keller plan in an atomic physics course at MIT are described, with emphasis on student performance and the administrative structure of the new format.

Previous work has indicated that two mechanisms of neutralization of the singly charged polonium ion exist. Charged Polonium-218 can be neutralized by reacting with oxygen to form a polonium oxide ion with a higher ionization potential than that of the polonium metal and then accepting an electron transferred from a lower ionization potential gas. In this present work, this mechanism has been verified by determining that the polonium oxide has an ionization potential in the range 10.35-10.53 eV. It was also previously reported that /sup 218/Po can be neutralized, in the absence of oxygen, by the scavenging of electrons by a trace gas such as water or nitrogen dioxide and their diffusion to the polonium ion. To verify this second neutralization mechanism, concentrations of nitrogen dioxide in nitrogen in the range of 50 ppb-1 ppm were examined for their ability to neutralize the polonium ion. Complete neutralization of /sup 218/Po was observed at nitrogen dioxide concentrations greater than 700 ppb. For concentrations below 700 ppb, the degree of neutralization was found to increase smoothly with the nitrogen dioxide concentration.

Novel liquid-crystal materials based on 1-alkyl-4-[5-(dodecylsulfanyl)-1,3,4-oxadiazol-2-yl]pyridinium bromide derivatives were synthesized. Their thermotropic polymorphism was investigated by polarizing optical microscopy and differential scanning calorimetry. The structures of their crystalline and smectic A phases were investigated by X-ray diffraction. The existence of thermochromic properties in the smectic phase as well as their UV−visible and fluorescence properties were also studied. The chemical structure of the compounds renders these materials suitable for optoelectronic applications.

Cylindrical compression experiments were performed on two different grades of optical glasses to measure their stress response to the applied strain at lens moulding temperatures. The temperature dependence of elastic (Young's) modulus of the two glasses was measured using the technique of Brillouin light-scattering, from ambient temperature to approximately 250 °C above the glass transition temperature. The measured high temperature material data were used as input to finite element method simulation of cylindrical compression as well as to the precision lens moulding process. Good agreement was obtained between stress relaxation patterns predicted from cylinder compression simulations and analytical models. The close agreement between predicted and experimental loads during lens moulding validates the viscoelastic material model.

High-cycle-fatigue (HCF) fracture mechanism of nickel-based superalloy IN 792 coated with Pt-modified aluminide outward-diffusion coating is studied with focus on the influence of coating cracks. It is found that cracking of the diffusion coating prior to HCF tests has little influence on the fatigue limit of specimens with thin coating (50 μm) but lowers the fatigue limit of specimens with thick coating (70 μm). By fractographic analysis, three types of fractural modes are established according to their crack initiations: internal, external and mixed. While external fractural mode is related to the propagation of existing cracks in the coating, internal facture initiates often at Ti-Ta-W-rich carbides and/or topological-close-packed (TCP) phases and grainboundaries in the superalloy. Increasing the thickness of diffusion coating or the amplitude stress promotes the fractural mode transition from internal/mixed to external. The influence of precracking of coatings on the HCF fracture mechanism can be qualitatively explained by its influence on the stress intensity factor.

Objective:To evaluate voiding dysfunction in cervical spondylotic myelopathy and improvement in the near future after surgery. Method: 51 patients with cervical spondylotic myelopathy were investigated about their voiding function, and they were all undergone uroflowmetry. The pre-operative and post-operative results were analyzed comparatively. Result:Before surgery,27 patients(52.9% ) had voiding dysfunction and 29 patients(56.9%) had abnormal flow rate. Patients with course more than 1 year, cervical OPLL, low spinal grades and patients whose symptoms arising from legs were found to be apt to have voiding dysfunction and abnormal flow rate. In the near future after surgery,symptoms of 19 (70.4%) of 27 patients with voiding dysfunction were improved and the maximum flow rate of the 29 patients with abnormal flow rate were improved significantly. Conclusion;Cervical spondylotic myelopathy may cause voiding dysfunction. Patients with course more than 1 year,cervical OPLL,low spinal grades and whose symptoms arising from legs are apt to have voiding dysfunction. Voiding function can be improved significantly in the near future after surgery.
