The present study was undertaken to analyse the performance of the dairy sector in India by using compound growth rate analysis and to determine the trends observed in the parameters. It was observed that the compound growth rate of the livestock population was 0.89 per cent, positive and significant from 1956 to 2019. Buffalo population has shown a positive and significant growth rate of 1.43 per cent and 0.31 per cent for cattle and 1.58 per cent for goats. In comparison to indigenous cows, exotic or crossbred cows showed a greater significant growth rate of 5.14 per cent against 1.71 per cent. There has been observed a positive and significant compound annual growth rate of 4.71 per cent to milk production and 3.26 per cent for per capita availability. Dairy cooperative societies, producer members, milk procurement and liquid milk marketing showed a positive and significant compound annual growth rate of 3.47, 2.31, 7.78 and 6.04 per cent respectively. The compound annual growth rate of exports in quantity showed a positive rate of 14.24 per cent and imports with a negative growth rate of 9.70 over the period which indicates that India is a net exporter of dairy products.


The recently deployed 4G access technology promises to satisfy the increasing demand of bandwidth consuming applications by providing high network capacity, low latency and seamless mobility. Towards this direction, concept solutions concerning the integration of wireless and optical networks have been proposed. However, the majority of these approaches assume the conventional fixed commitment of resources to the base stations, an inefficient and costly process, especially in case the Passive Optical Network (PON) belongs to a different operator. As a result, new, more dynamic backhaul resource allocation approaches are required. In this paper, the authors study the problem of committing resources of the backhaul network to a base station by employing evolutionary game theory in order to model the interactions between the subscribers and the base station. The asymptotic stability of the proposed scheme is proven under the replicator dynamics model. Finally, the impact of time delay in the proposed scheme is also investigated.


Context. There is a group of about twenty galaxies around the giant radio galaxy (GRG) DA 240 which we are studying to investigate the environment of the radio source. We have noted that 11 members are aligned with the radio emission (Peng et al. 2004, A&A, 415, 487). The alignment occurs within a small angle similar to the width of the GRG radio lobes, and there may be some physical causal relationship. After finishing observations of the four candidates not included in Paper I, we have completed our study of the brighter members of the sample of galaxies around DA 240.

Aims. We aim to see if more galaxies have similar redshifts to the host galaxy of DA 240, to confirm the galaxy grouping and further study their distribution.

Methods. Spectra of the four candidate galaxies were obtained with the 2.16 m spectroscopic telescope at XingLong observing station of the NAOC, and the galaxies' positions were established with respect to the radio emission. We have discovered two more members associated with the group of galaxies around DA 240. In addition, the work of other researchers provides one other new member.

Results. The number of confirmed galaxies associated with the DA 240 group has increased by almost a quarter to 20. There are now 14 galaxies (including the host) lying along the major axis of the radio source. We further consider the relationship of the group to adjacent galaxy associations, noting that it may form a binary pair with the slightly closer UGC 3957 group. They both lie on the periphery of the much more substantial cluster, Abell 576.


Baseband digital predistortion (DPD) techniques for linearizing
power amplifiers (PA) with memory effects are
investigated in this thesis. Firstly, the relevant elements
concerning PA linearization are introduced, such as PA
nonlinearity behavior, its influence on the communication
systems, its modeling and characterization... Then
some existing linearization techniques are presented,
such as power backoff, feedforward, feedback, linear
amplification with nonlinear components and DPD.
DPD is the most promising linearization technique. After
that, the implementation architecture and identification
algorithms of DPD are described. In this thesis,
four DPD methods are proposed. The first method
(MP/LUT DPD) is to combine a memory polynomial
(MP) model and a simple non-interpolated LUT. Both
the amplitude and phase of the predistorted signal are
calculated by LUT. The second method is to add linear
interpolation technique to MP/LUT DPD. The third
method improves the second one by using a quadratic
interpolation technique to MP/LUT DPD. The fourth
method is to combine MP DPD and feed forward neural
network. The principal innovation is that the training
samples of the neural networks are the predistorded
signal obtained by MP DPD. Finally, simulation results
and experimental results are given and analyzed. The
proposed methods provide different trade-off between
the linearization performance, time efficiency and complexity.

This research investigates the techno-economic assessment of a hybrid grid system of solar and wind power for a residual urban area in Khvaf town located in the eastern part of Iran. The temperature profiles of a 10-year period are gathered based on the existing solar and wind condition data. Simulation, economical and technical evaluations of this hybrid system are studied with the aid of HOMER software. To reach a proper independent structure from the total net present cost and energy cost viewpoints, thousands of cases were studied. Change of the factor investing on PV panels together with the amount of the sun radiance as well as change of the investment factor of wind turbines with the consideration of wind velocity and sun radiance on the system layout are studied and discussed. The initial investment is 440 thousand dollars and the contribution portion of the renewable energies is 84% for the case containing four wind turbines and a power grid system (optimal system). This optimal system returns the investment over a 4-year period which is very economically attractive. The optimal system for the case with a low mean wind speed of 3 m/s is preferred to involve 13-kW photovoltaic (PV) panels, one-wind turbine and a 10-kW converter with a power grid network. Results shown that when the cost of the PV panel is 0.6 times higher than the current cost, a system consisting 4-wind turbines connected to the grid network is still the optimal system. In addition, a sensitivity analysis is made on the load demand of the hybrid system and the renewable energy resource. As a result, the most influential variables on the performance of the system are identified in this research. Based on the economic and technical evaluation, establishing a hybrid grid system for a residential urban area is perfectly reasonable with the investment return during the fourth year of a 25-year project lifetime. Also, among the systems studied, a system with four wind turbines and a power grid system is chosen as an optimal system due to the fact that the region has favorable potential for wind energy.


William Butler Yeats was throughout his life determined to relate his words to music, and involved many writers and musicians in his search for the key. While in Rapallo staying near Ezra Pound, he met the young composer George Antheil, who became one of his converts. Others followed, with Yeats continuing to expound and clarify his ambition.


It is shown that the C-8 ethyl group of bacteriochlorophyll a(5) is formed by the addition of hydrogen to C-81 from the si-face of the corresponding double bond [4; Δ(81,82)]; this observation, when taken in conjunction with the previous finding regarding the stereochemistry of hydrogen addition to C-82, reveals that the overall saturation process occurs via the formal trans-addition.


[eng] Socioeconomic inequalities affect all areas of consumption. Disparities in food consumption have nutritional consequences that may contribute to social inequalities in health. Drawing on 40 years of representative data at the household level (1971-2010), this paper examines changes in the major food groups and nutritional quality in at-home consumption by income and education. In a global trend of improving nutritional quality over the period, the study provides evidence of a positive trend for all income quartiles and for four levels of education. Inequalities were significant at the beginning of the period but on the decline in the 2000s: they were very pronounced between education levels in the 1970s but appear to be on the verge of disappearing by 2010; according to income level, they were limited and on the decline until 2010, but still persist.


Ferroelectric memories experienced a revival in the last decade due to the discovery of ferroelectricity in HfO$_2$-based nanometer-thick thin films. These films exhibit exceptional silicon compatibility, overcoming the scaling and integration obstacles that impeded perovskite ferroelectrics' use in high-density integrated circuits. The exact phase responsible for ferroelectricity in hafnia films remains debated with no single factor identified that could stabilize the ferroelectric phase thermodynamically. Here, supported by density functional theory (DFT) high-throughput (HT) calculations that screen a broad range of epitaxial conditions, we demonstrate conclusively that specific epitaxial conditions achievable with common substrates such as yttria-stabilized zirconia (YSZ) and SrTiO$_3$ can favor the polar Pca2$_1$ phase thermodynamically over other polar phases such as R3m and Pmn2$_1$ and nonpolar P2$_1$/c phase. The substrate's symmetry constraint-induced shear strain is crucial for the preference of Pca2$_1$. The strain-stability phase diagrams resolve experiment-theory discrepancies and can guide the improvement of ferroelectric properties of epitaxial hafnia thin films.


Indian English Poetry before and after Independence are open to discuss and debate. And we can also divide Indian English Literature from 1930s to the end of 20th century into two phases: Modernism and Postmodernism. Modernism came along with Raja Rao"s "Kanthapura"(1938) and Postmodernism came with Salman Rushdie"s "Midnight"s Children"(1981). Actually literature after 1980 came to be known as Postmodern Literature. In case of poetry Nissim Ezekiel"s "Letter-Day Plasm"(1982) marked the beginning of postmodern Indian English Poetry. So many poets came after Ezekiel and wrote poetry bearing the tagline created by Ezekiel. Among them, Jayanta Mahapatra"s work can be said to embody the characteristics of Postmodernism in the last two decades of the twentieth century. In his paper, I have attempted to show Jayanta Mahapatra as a Postmodern Indian English Poet through some of his eternal verse. Keywords: Postmodernism, History, Rootedness, Indian woman, Love, Contemporary condition.


Induction Heated Friction Stir Welding (IH-FSW) was conducted using two varying parameters and two fixed parameters. The microstructure evaluation shows that the nugget zone's grain size is smaller while comparing with the parent metal. Due to dynamic recrystallization during the induction heated friction stir welding, well-equiaxed grains were found in the nugget zone. The microhardness test reveals that the welded region have improved hardness than the parent metal; the high hardness was attained in the heat-affected zone. The 3 h and 24 h of weight-loss corrosion test methods were conducted using the coefficient of 0.5 M H2SO4, showing that the stir zone's corrosion resistance is better than the parent material. The given parameter combinations obtain the best results, tool rotation of 1250 rpm, welding speed of 45 mm min−1, shoulder penetration of 0.50 mm and induction heat input of 441.8 °C at 50 W.


Possibility of incorporation of tritium-containing pump oils absorbed by thermally expanded graphite into unsaturated polyester resin matrix is considered. The rate of tritium leaching from the matrix is estimated. Influence of pump oil on the polymer burning is shown and the burning inhibitor is chosen. Tests of the polymer blocks' compressive strength are performed.


Male guniea-pigs, immunized with testicular antigens in Freund's incomplete adjuvant, were mated. The presence of antisperm antibodies in the sera of guinea-pig boars did not result in infertility, decreased fertility or diminished litter size, although γ-globulin persisted on the epididymal sperm of immunized animals for prolonged periods.


We study spontaneous symmetry breaking in phi^4_(1+1) using the light-front formulation of the field theory. Since the physical vacuum is always the same as the perturbative vacuum in light-front field theory the fields must develop a vacuum expectation value through the zero-mode components of the field. We solve the nonlinear operator equation for the zero-mode in the one-mode approximation. We find that spontaneous symmetry breaking occurs at lambda_critical = 4 pi(3+sqrt 3), which is consistent with the value lambda_critical = 54.27 obtained in the equal time theory. We calculate the value of the vacuum expectation value as a function of the coupling constant in the broken phase both numerically and analytically using the delta expansion. We find two equivalent broken phases. Finally we show that the energy levels of the system have the expected behavior within the broken phase.


Sustainability is an emerging area of investigation within the entrepreneurial leadership literature. Therefore, it is critical to understand more about how an entrepreneurial leadership style can influence the sustainable behaviour of employees. With the use of current literature and interviews with managers in Germany and the Netherlands, this study developed a model about the effect of entrepreneurial leadership on sustainable employee behaviour. The model explains how entrepreneurial leaders can influence employees' sustainable behaviour in several ways. Stimulation of sustainable behaviour can be done by correcting unsustainable behaviour, showing role model behaviour, giving autonomy, support, responsibility and ownership to employees as well as raising awareness and learning from competitors. Employees react in different ways to the stimulation of sustainable behaviour by the application of an entrepreneurial leadership style. Employees react with motivation, commitment, creativity and learning but also giving signals of being overtaxed. The study has shown a dependency on the contingency factors company perspective, as well as attitude and personality of employees and entrepreneurial leaders. Both, the entrepreneurial leadership style applied to stimulate sustainable behaviour and employees being confronted with this leadership style are influenced by these contingency factors. This research adds to existing literature by setting directions for leaders on how to use an entrepreneurial leadership style to stimulate employees' sustainable behaviour. In addition, there are not many models about the stimulation of employee's sustainable behaviour yet, so this model could be used as a basis for further research on this topic.


An improved banjo head is described which provides a deeper and more mellow sound to the banjo. The new head also allows for sound pick up and amplification from each string. The new banjo head comprises a thin flexible membrane having a hole positioned on the periphery of this membrane and a means to reinforce said hole.


Accompanying to the coming of western powers,nationalism which stresses the ultimate and exclusive political loyalty to the building of "nation-state" has prevailed in Asia since the turn of the twentieth century.Interestingly,Chinese who migrated to the British Malaya had developed a double national identity,not the exclusive national identity stressed by western countries in modern times.


In this paper we obtain some coincidence point results of a family of multivalued mappings with a singlevalued mapping in a complete metric space endowed with a partial order. We use δdistance in this paper. A generalized weak C-contraction inequality for multivalued functions and δ-compatibility for certain pairs of functions are assumed in the theorems. The corresponding singled valued cases are shown to extend a number of existing results. An example is constructed which shows that the extensions are actual improvements.


The common usage of flow cytometry (FCM) in research and clinical diagnostic is limited by the lack visualizing the fluorescence labelled cells. The Laser Scanning Cytometer (LSC) enables multicolor cytometric measurements on a slide featuring relocation of single cells for further investigation via brightfield and fluorescence microscopy. Additionally, it is possible to capture these images for documentation. In a FISH application, the LSC was successfully used for automated scoring techniqeus for evaluating the frequency of aneuploid sperm in humans and mice. In just 30 minutes, we were able to acquire more than 15,000 sperms, a task which normally takes more than a day. After relocation, genetic defects were identified and confirmed via fluorescence microscopy. In an on going study, we investigate via the LSC the remain of a new radiopaque material for high resolution echocardiography in the blood circulation. At first the result exhibited that the radiopaque material is endocysed by leukocytes just after application but is still detectable via echocardiography for up to 40 minutes. In conclusion, with the additional data acquisition by the LSC, it is possible to perform further detailed information from very small samples. Therefore, we are working up to now on developing new methods to introduce the LSC in our clinical diagnostic of neonates undergoing cardiac surgery.


Purpose
This research aims to explore the role of social capital and specifically networks in role, and career development for women within two very distinct gender-segregated contexts of the labour market, namely, investment management and human resource management (HRM).

Design/methodology/approach
This research is qualitative in nature, underpinned by an interpretivist philosophical stance. Thematic analysis is used to analyse the findings from 32 in-depth interviews with HR and investment management managers.

Findings
The findings advance our understanding of social capital and its development as a social process, which differs according to labour market contexts. The results indicate divergence among participants regarding how they access networks as well as the perceived role and benefits of networking and social capital accumulation in their career and personal development.

Practical implications
For human resource development (HRD) practitioners, there are implications in relation to the need to tailor development and support structures cognisant of the occupational context. Specifically, the findings of this study indicate the acute need to support network access for those "outsider" women in male-dominated spaces. A need to enhance awareness of the benefits of networks to both organisations and employees across the labour market is warranted. For organisations, networks underlie social capital accumulation, which in turn increases efficiency and generates business solutions. For the employee, networks are an important self-development and career advancement tool. Such connections need to be supported and developed. Within patriarchal spaces particularly, HRD professionals need to provide support to women in extending their networks both within and outside the organisation.

Originality/value
This research makes an essential contribution to the literature by examining the influence of context in the development of social capital within two polarized labour market locations. The findings highlight the difficulties women face when developing social capital in investment management in contrast to the relative ease, which HRM professionals experience. Such findings also bring to light the essential role of HRD professionals as advocates for change in such contexts.

1 Webster's Seventh New Collegiate Dictionary (Springfield: G. & C. Merriam Co., 1963), p. 656. 2 Ibid., p. 233. The question before us is this: How can we act wisely in management of the field course, how can we select a plan of action to guide present and future decisions, when we are confronted only with choices between equally unsatisfactory alternatives, problems seemingly incapable of satisfactory solutions? The one hopeful note here is the use of the word "seemingly": some of our dilemmas, if studied carefully enough, may be transformed into problems that will yield to rational solutions. Certain complaints about field instruction are repetitively3 and strongly expressed: It costs too much; it takes too long; it limits enrollment; there isn't enough time; students don't know enough when they com-


Abstract
As with previous transport innovations, the transition to 'smart mobility' will occur in different ways and at different speeds in different places. Innovations such as Uber and trials of autonomous vehicles are already being welcomed in some places but resisted in others or left to the market. While the technologies may have the potential to be deployed globally, how this happens is, in part, down to the institutional settings and approach to governance amongst all of the actors (public and private) involved. Deciding who should act, how, when and at what spatial scale is, we argue, critical in setting the conditions in which new mobility systems can flourish but in a way which promotes the goals of local, state and federal governments and meets the needs of citizens as well as the industries that promote them.

This chapter reports on an international scenarios exercise conducted in 2017 across nine countries. Key dimensions of uncertainty were the degree of governmental involvement in steering policy and the degree of social desirability for smart mobility innovation. Reflecting on the period up to 2035, the scenarios considered the implications for smart mobility transitions by asking which innovations are more likely to flourish and which falter. Strong state involvement is reported as a necessary condition for the most integrated and sustainable visions of smart mobility. Other pathways were suggested to favour some innovations over others but typically offer a smaller market and more atomized and less sustainable set of mobility options.


We investigate the optical counterparts of recently discovered Be/X-ray binaries in the Small Magellanic Cloud (SMC). In total four sources, SXP101, SXP700, SXP348 and SXP65.8 were detected during the Chandra survey of the wing of the SMC. SXP700 and SXP65.8 were previously unknown. Many optical ground-based telescopes have been utilized in the optical follow-up, providing coverage in both the red and blue bands. This has led to the classification of all of the counterparts as Be stars and confirms that three lie within the Galactic spectral distribution of known Be/X-ray binaries. SXP101 lies outside this distribution and is the latest spectral type known. Monitoring of the Ha emission line suggests that all the sources barring SXP700 have highly variable circumstellar discs, possibly a result of their comparatively short orbital periods. Phase-resolved X-ray spectroscopy has also been performed on SXP65.8, revealing that the emission is indeed harder during the passage of the X-ray beam through the line of sight.


The antiseptic, antibacterial, and antifungal properties of the essential oil of Melaleuca alternifolia, commonly called tea tree oil (TTO), are well-known. This mixture of monoterpenes, sesquiterpenes, and their alcohols is utilized in many therapeutic and cosmetic applications, directly as essential oil or in different kinds of formulations. The terpinen-4-ol, which is present in the commercial essential oil samples in the minimum amount of 30 wt %, is recognized as the main active agent of TTO. Considering the good performance of lipid-based liquid crystalline phases as drug delivery systems, the monoolein/water system has been assessed for both terpinen-4-ol and TTO formulations. The phase behavior of the ternary systems has been investigated by means of optical microscopy and 2H NMR quadrupolar splitting. 13C NMR spin−lattice relaxation times and self-diffusion coefficients (measured by 13C NMR PGSE technique) of the lipid matrix and the active agent have been determined to give insights on the dynam...

Case 1 A 33-year-old parous woman booked in her fourth pregnancy at 12 weeks' gestation. She had three normal vaginal deliveries prior to this pregnancy. Her booking visit was at 12 weeks' gestation at which time triplets were diagnosed. Serial fetal assessment scans were carried out at 18, 23, 25, 26 and 28 weeks' gestation. At 29 weeks' gestation she presented in labour with a history of spontaneous rupture of the membranes. On examination she was fully dilated and the ® rst triplet was crowning . The second baby was also cephalic in presentation and delivered vaginally, the third was delivered by breech extraction. The infants were all male and weighed 1 ́28 kg, 1 ́23 kg and 1 ́2 kg. They were transferred to the special care baby unit and all had an uneventful neonatal course.


Polymer representation of quantum mechanics is an effective approach to loop quantum gravity. In this paper we develop statistical mechanics in the polymer framework. While to obtain energies of microstates one needs usually to solve the polymer-modified Schr\"{o}dinger equation, we have not adopted this strategy here since it is not an easy task due to the complicated form of the Schr\"{o}dinger equation in the polymer picture. Instead, we formulate the ensemble theory in polymer framework in a semi-classical regime through deformed density of states. We show that our results are in good agreement with those arising from quantum mechanical considerations. Applying this method to thermodynamics of quantum Schwarzschild black hole, we obtain corrections to the Bekenstein-Hawking entropy due to loop quantum gravity effects.


We simulate the Kardar-Parisi-Zhang equation [Phys. Rev. Lett. 56, 889 (1986)] in 2+1 dimensions. It is a nonlinear stochastic differential equation that describes driven growing interfaces. The Hopf-Cole transformation is used in order to obtain a stable numerical scheme. The two relevant critical exponents are precisely measured.


The single temperature pulse technique, developed at the Cornell Aeronautical Laboratory, has been used to study the kinetics of the formation of nitric oxide in the temperature range from 2000° to 3000°K. It has been found that the kinetics of the reaction are consistent with the chain mechanism proposed by Zeldovich. The rate‐determining step in the chain is: O+N2→NO+N, with ΔH25000=75.8 kcal/mole. The activation energy for this step is found to be 74±5 kcal/mole. The collision cross‐section, as calculated from classical reaction rate theory, is 10—16 cm2, which corresponds to a steric factor of about 0.05, assuming σN2,O=5 A.


It is no doubt that the DSRC technology will play an important role in ITS. It equipped with seven channels that are designated for rich applications to improve the driving safety and support non-safety services. And there is a multi-channel coordination issue for the latter. This paper proposed a novel multi-channel scheduling algorithm for DSRC networks .The target of the multi-channel scheduling algorithm is to take full advantage of the DSRC frequency resource. The algorithm is suitable for the DSRC multi-channel architecture, and the performance evaluation shows the algorithm is feasible for DSRC.

Hawaii is located within a hurricane hazard region, where the governing extreme winds are produced by rare tropical cyclones and not by regular wind climatology. In Hawaii, wind may govern the structural design in many cases, while seismic effects may dominate in others. Topographic amplification of wind speed has been a significant contributing factor in the past hurricane loss experiences of Hawaii. In the Hawaiian islands, where the real terrain is often very complex or characterized by large shield mountain features, the actual magnitude and extent of speed-up can be quite different from the present ASCE/SEI 7 prescriptive calculations. New wind speed design mapping and technical provisions have been developed as local code amendments to the International Building Code (IBC), based on requirements of the ASCE/SEI 7-05 wind load standard. Customized wind design maps were developed from computational fluid dynamics mesoscale models, and site-specific wind-tunnel tests. The methodology accounts for: 1) specification of topographic effects factor Kzt, 2) directionality weighting, Kd, in consideration of the probability of critical windspeed, and 3) mapping of Exposure Categories for determination of Kz exposure coefficient. With the adoption of these new micro-zoned wind design maps defining customized values of ASCE/SEI 7 parameters within a Hawaii State Building Code, a uniform level of protection for hurricane hazard will be specified for the structural design of new buildings in Hawaii.


<italic>Geo-social group</italic> queries, which return a social cohesive user group with a spatial constraint, have receive significant research interests due to their promising applications for group-based activity planning and scheduling in location-based social networks (LBSNs). However, existing studies on geo-social group queries mostly assume the users are stationary whereas in realistic LBSN application scenarios all users may continuously move over time. Thus, in this paper, we investigate the problem of <italic><underline>c</underline>ontinuous <underline>g</underline>eo-<underline>s</underline>ocial <underline>g</underline>roups <underline>m</underline>onitoring</italic> (<italic>CGSGM</italic>) over moving users. A challenge in answering CGSGM queries over moving users is how to efficiently update geo-social groups when users are continuously moving. To address the CGSGM problem, we first propose a baseline algorithm, namely <italic>Baseline-BB</italic>, which recomputes the new geo-social groups from scratch at each time instance by utilizing a branch and bound (BB) strategy. To improve the inefficiency of BB, we explore a new strategy, called common neighbor or neighbor expanding (CNNE), which expands the common neighbors of edges or the neighbors of users in intermediate groups to quickly produce the valid group combinations. Accordingly, another baseline algorithm, namely <italic>Baseline-CNNE</italic>, is proposed. As these baseline algorithms do not maintain intermediate results to facilitate further query processing, we develop an incremental algorithm, called <italic>incremental monitoring algorithm (IMA)</italic>, which maintains the support, common neighbors and the neighbors of current users when exploring possible user groups for further updates and query processing. Since IMA requires many times of truss decomposition when processing mutiple-users updates, we propose an improved incremental algorithm, called <italic>improved incremental monitoring algorithm (IIMA)</italic>, which performs truss decompostion only once. Moreover, we design algorithms for handling the social changes that result in insertion/deletion of some edges in the social network. Owing to the challenge in setting, an appropriate monitoring distance, we further study the top <inline-formula><tex-math notation="LaTeX">$N$</tex-math><alternatives><mml:math><mml:mi>N</mml:mi></mml:math><inline-graphic xlink:href="zhu-ieq1-3218844.gif"/></alternatives></inline-formula> CGSGM problem, which finds top <inline-formula><tex-math notation="LaTeX">$N$</tex-math><alternatives><mml:math><mml:mi>N</mml:mi></mml:math><inline-graphic xlink:href="zhu-ieq2-3218844.gif"/></alternatives></inline-formula> result groups at each time instance. Finally, we conduct extensive experiments using four real datasets to validate our ideas and evaluate the proposed algorithms.


Relay protection device is important for the stable operation of power system and protected electrical equipment.It is very important for the reliable operation of power system protection devices to select reasonable protection way and correctly conduct setting calculation.In the component parts of power system,distribution lines running conditions is bad,and risk of accidents is much higher than the other equipment,so the relay protection device is more important.This paper mainly discusses protection configuration and the computation of 220Kv high voltage transmission line relay.


The practice of digital transformations is associated with the tasks of providing a mature digital enterprise infrastructure.

Interactions between supervisor and supervisee during consultation particularly in the postgraduate level are essential in the completion of a thesis or dissertation. In most interactions, both speakers; the supervisor and the supervisee assert their identities who they are. Such scenario has been an important phenomenon to examine how stance-taking and identity construction are portrayed. This research specifically examined 10 conversations between supervisors and supervisees during research consultations at the University of Malaya, Kuala Lumpur, Malaysia. The study combined the Stance Triangle and Model of Stance Marker as theoretical framework in analyzing the construction of identity between supervisors and supervisees. In addition, conversation analysis was used as an approach in analyzing the data. The findings of the study show that in supervisor-supervisee interaction certain stages are followed in the conversational structure. This study reveals that there are 6 stages in supervisor-supervisee interaction, such as, making follow-up, testing the knowledge of the supervisee, giving suggestion, seeking for clarification, giving recommendation and making conclusion. In every stage, it shows that different stance takings are used by both supervisors and supervisees. Furthermore, the study reveals that epistemic stance markers, textual stance markers, attitudinal stance markers and deontic stance markers are commonly used. In every stance that supervisors and supervisees take, they tend to position their identities. Such identities shift from one stage to another. Generally, the supervisors position themselves as mentor, expert, counselor, knowledgeable, controlling and responsible. On the other hand, supervisees position themselves as mentee, neophyte, counselee, learner, follower and grateful.


A higher habitat suitability resulting from a combination of basic site and temporary agricultural factors brings about an increase in the parameters cocoon number and cocoon biomass, whereas the parameter mean cocoon mass appears to be more resilient to temporary changes and may better reflects more stable site conditions. Choice of biological parameter, therefore, is important when applying the concept of bio-indication to environmental conditions, particularly with regard to long- and short-term fluctuations


This paper presents performances of two-phase cooling of a chip at very high heat flux with refrigerant R236fa in a silicon multimicrochannel heat sink. This heat sink was composed of 134 parallel channels, 67 mum wide, 680 mum high, and 20 mm long, with 92- mum -thick fins separating the channels. The base heat flux was varied from 3 to 255 W/cm2 , the volume flow rate from 0.18 to 0.67 I/min, and the exit vapor quality from 0 to 80%. The working pressure and saturation temperature were set at 273 kPa and 25 degC, respectively. The present database includes 1040 local heat transfer coefficients. The base temperature of the chip could be maintained below 52 degC while dissipating 255 W/cm2 with 10 degC of inlet subcooling and 90 kPa of pressure drop. A comparison of the respective performances with an extrapolation of the present results shows that two-phase cooling should be able to cool the chip 13 K lower than liquid cooling for the same pumping power at a base heat flux of 350 W/cm2.

The Jinchuan intrusion consists of pyroxene dunite,lherzolite,plagioclase lherzolite and olivine pyroxenite and hosts the third largest magmatic Ni-Cu-(PGE)sulfide deposit in the world.Petrography indicates that the crystallization sequence of the main rock-forming minerals of the Jinchuan intrusion was olivine → orthopyroxene → clinopyroxene → plagioclase.Based on rock textures and compositions of the dominant rock-forming minerals,the more precise composition of the parental magma of the Jinchuan intrusion have been obtained by using the thermodynamic code "MELTS":48.2% SiO2,1.00% TiO2,11.3% Al2O3,12.9% FeO,1.30% Fe2O3,12.6% MgO,10.1% CaO,1.51% Na2O,0.72% K2O,0.04% NiO.The thermodynamic simulation also indicated that the parental magma experienced two stages of fractional crystallization.In the first stage,crystallization of about 5% olivine and 4% orthopyroxene as well as sulfide liquid immiscibility occurred in a magma chamber at a depth of 10.9~12.5km(pressure is 3.3~3.8kbar).Stratigraphic zones from the base to the top of the deep staging magma chamber were formed due to gravity segregation,including olivine-orthopyroxene-sulfide-silicate liquid mush,olivine-orthopyroxene-silicate liquid mush,silicate magma.The silicate magma was squeezed out firstly to form some sulfide poor mafic intrusions or erupted to the surface elsewhere.The olivine-orthopyroxene-silicate liquid mush was squeezed to the shallower magma chamber at a depth of about 7.6~9.2km and formed the upper sequences of the Segment I and the upper pyroxene dunite in the Segment II of the Jinchuan intrusion.The olivine-orthopyroxene-sulfide-silicate liquid mush lastly intruded into the shallow magma chamber,where further crystallization of olivine,clinopyroxene,and plagioclase occurred and formed the main rocks and sulfide ore bodies of the Jinchuan intrusion.These results are consistent with the petrology and petrography of the Jinchuan intrusion,and also are consistent with the results of recent studies on the formation of the Ni-Cu sulfides.


Wavelength tuning of fiber Bragg gratings (FBGs) by virtue of a lateral or transverse load is attractive for a variety of applications in the field of optical sensing. The wavelength response characteristic of the FBG upon application of a transverse load is highly dependent on the pressurizing media and the contact conditions. In this paper, we evaluate the effect of contact friction and contact angle of the pressurizing media on the lateral pressure tuning of FBGs. Our results showed that pressurizing media with a lower value of stiffness is favorable for greater contact areas and for distributing the lateral load. Thus, the sensing load becomes more hydrostatic in nature, which enhances the lateral pressure sensitivity and tuning range while reducing birefringence. Also, a higher contact friction is favorable for effective transfer of the load through the contact area and improved sensitivities accordingly. The present study is thus useful in better utilization of lateral pressure tuning of FBGs for sensing applications.


to PPB, relatively little objective analysis has been reported of the limitations or effectiveness of such systems once in operation. In the words of Frederick Mosher, &dquo;there has been little objective and evaluative analysis of what PPBS has accomplished and failed to accomplish in any area-even the Defense Department.&dquo;1 To begin correcting such a situation, this study is concerned with identifying some of the major limitations encountered by PPB systems as instituted at the state and local level, and suggesting an explanation for some of these limitations. It draws on the author's own experience with program-budgeting at the state level, and corroborates resulting observations by referring to reports of others in the area.


The influence of two kinds of contamination on sequential confidence intervals for the mean of a normal population is studied when the contamination probability tends to zero with the length d of the confidence interval. It is shown that if ∊/d → a>0 the mean of the asymptotic distribution of the stopping variable (properly normalized) of eachprocedure considered is of special interest.In the case of contamination by a point mass, the asymptotic mean is closely related to the influence function of the measure of spread in the definition of the stopping rule. For the Chow Robbins procedure the influence function of the standard deviation appears and this is unbounded. If the standard deviation in this procedure is replaced by a fractile difference estimator, the influence function, and hence the asymptotic mean, remains bounded. Similar results are obtained for a gross errors contamination model. The asymptotic coverage probability of both procedures is biased under the nonsymmetric point mass contaminatio...


Christina Firpo's latest book is a lively social history of the black market sex industry in late French colonial northern Vietnam, known then as Tonkin (1920–45). Focusing on impoverished Vietnamese women, an understudied group in the historical scholarship, Firpo maintains that the booming underground sex industry thrived because of what she calls the "spaces of tension" (p. 3) brought about by the inequality and discord of colonial policies. The policies led to inconsistencies in law, culture, economics, geography and demography that incentivized historical actors—pimps, madams, kidnappers, traffickers, sex workers—to exploit loopholes to seek out more favourable economic opportunities. The portrait that the book paints is nevertheless a sobering one. For the female sex workers whose lives Firpo reconstructs, most of whom were rural migrants, the sex industry was often the last resort to survive. Working conditions, as Firpo demonstrates, were often poor with high risks of catching venereal diseases. Chapters 1 and 2 establish the geographical and legal contexts of Tonkin's illicit sex industry. Chapter 1 looks at the "geography of vice" (p. 20), surveying sex work's spatial dimensions. Firpo shows how each of the different geographic conditions—whether physical, political, economic or urban—shaped the migration and distribution of sex workers. Colonial policies that impoverished peasants forced


Numerical analyses considering the influence of the contact resistance and the type of material of the conductive elements in a closed low voltage distribution block are carried out for the electric and thermal field of the block. A 3D model of the block in the software product COMSOL has been used to conduct the analyses. Results, related to the distribution of the electric and thermal field at increased contact resistance and when using conductive elements made of copper or aluminum have been got.


Many solids remain elastic to strains of a few percent when subjected to uniaxial strain imposed by shock loading. Nonlinear contributions are enhanced by such large elastic strains and become accessible for relatively straightforward measurement and interpretation. Impact loading techniques have proven particularly effective for measurements of second‐, third‐ and fourth‐order longitudinal piezoelectric constants as well as third‐ and fourth‐order longitudinal elastic constants. Shock compression studies have provided independent measurements of constants, have uniquely determined certain constants and have extended ultrasonic measurements by several orders of magnitude in strain. Typical experimental investigations and their results will be summarized and compared to corresponding ultrasonic data.

Sociology of music as a not fully developed fi eld of study, especially in Poland seems to have strong 'personal' basis for scientifi c existence. Because we can fi nd in works of international classics of sociology musical plots. Herbert Spencer, Georg Simmel and Max Weber dealt with music sociologically. Also others (non-classics, but wellknown) scientists like Th eodor Adorno or Howard Backer were writing in this subject. In this text I will have a look on ideas about music shown in works of the classics of sociology and also I will note reception of those ideas in Polish sociology of music. K e y w o r d s : classics of sociology, reception of sociology in Poland, sociology of music, sociological sub-disciplines.


Solid lipid nanoparticles have been extensively investigated as drug delivery systems. These colloidal systems have major advantages compared to others more traditional. Reported advantages include sustained release, ability to solubilize lipophilic drugs, increased physical and chemical stability of labile molecules, decreased unwanted side-effects showing lower toxicity, and scale up facilities. This paper aims at reviewing the traditional methods of solid lipid nanoparticles production, such as fusion-emulsification (hot and cold), solvent evaporation-emulsification and microemulsion, dealing with the main technological parameters that influence the quality properties of solid lipid nanoparticles.


The accuracy of discrete models for the inverse dynamics is studied. The partial differential equation (PDE) modeling a flexible arm is referred to as a continuous model, and discretizations resulting in systems of ordinary differential equations (ODEs) are referred to as discrete models. The tracking order of the inverse dynamics for a single-link flexible arm is derived from a continuous model of the plant in the case where there is no tip mass. It is shown how discrete models may fail to identify this tracking order. Problems arising when discrete models are used are identified and solved in the frequency domain.<<ETX>>

Hip fractures are a major health concern among older persons with Alzheimer's disease, who usually use many concomitant drugs for several diseases. Evidence of the association between proton pump inhibitor use and risk of hip fracture is contradictory.


The Writer in the Quebec Novel, 1960-1995. The writer in this corpus faces two contradictory callings, that of social engagement and that of play. The dilemma does not move towards resolution, if the link between it and the vexed question of Quebec identity appear more clearly-but not more forcefully.


Abstract The hospitality industry in Tennessee employs 181,300 people as seasonal workers; fifty-three percent of those workers come from the school system. The loss of seasonal workers with the implementation of year-round schools will drastically increase the current labor shortage. An alternative labor pool needs to be identified and the issue of year-round schools must be addressed.


Sirs, Familial Mediterranean fever (FMF) is an autosomal recessive disease characterised by recurrent febrile inflammatory attacks of the serosal and synovial membranes (1). Secondary (AA) amyloidosis is the most common renal complication of FMF (2). Non-amyloid renal lesions have also been described. This is the first report of an FMF patient whose case was complicated by both secondary amyloidosis and necrotizing crescentic glomerulonephritis with granulomatous vasculitis. The patient was a 51-year old woman who suffered from attacks of fever and abdominal and pleural pain since the age of 20. She was diagnosed with FMF at the age of 46, and placed on colchicine treatment. However, she did not take this treatment regularly.A sister and a brother also had FMF. She was admitted to our hospital because of painless macroscopic haematuria which had begun two weeks earlier. Her history was unremarkable with regard to drug use. Her physical examination and laboratory studies were unremarkable except for ESR (75 mm/h) and CRP (17.7 mg/dL). In urinalysis, heavy proteinuria (6 g/24 h) was detected along with red blood cells, leukocytes and rare hyalen casts in the sediment. The glomerular filtration rate was 75 ml/min. The urine culture remained sterile for non-specific bacteria and mycobacteria. C3 and C4 levels were normal. Investigations for cryoglobulin and cryofibrinogen, HbsAg, anti-HCV, ANA and ANCA were negative. CT imaging of the thorax and paranasal sinuses were normal. Bilateral renal size and parenchymal echogenity were normal on ultrasound. Kidney biopsy revealed extensive glomerular sclerosis, abundant cellular crescent formation and evidence of granulomatous vasculitis (Fig. 1). Immunofluorescence studies were negative for immunoglobulins and complement components. Congo red stain was positive for amyloidosis which did not persist after potassium permanganate treatment; polarization microscopy revealed the typical green/yellow birefringence of amyloid. She has been treated with colchicine 2 mg/day and azathioprine 100 mg/day for two years. In her recent follow-up examination, she was asymptomatic; serum creatinine was 0.8 mg/dl, urinalysis showed 1 to 2 red cells and 0.5 g/day protein excretion. Renal involvement is an important feature of FMF and the first identified renal lesion was secondary (AA type) amyloidosis which usually presents with permanent proteinuria without a nephritic urine sediment (1,2). Long-term colchicine treatment can prevent the development of secondary amyloidosis (2). In our patient, the delay in the diagnosis of FMF and poor drug compliance may have contributed to the development of amyloidosis. Other renal lesions described in patients with FMF include mesangial proliferative glomerulonephritis, IgA nephropathy, IgM nephropathy, focal and diffuse proliferative glomerulonephritis, mesangiocapillary glomerulonephritis, membrano-proliferative glomerulonephritis and rapidly progressive glomerulonephritis (3-7). Also, some of the non-amyloid glomerular lesions described in patients with FMF were associated with vasculitis (3, 5, 8). Some forms of vasculitic disorders are known to be associated with FMF; these include polyarteritis nodosa, HenochSchönlein purpura, protracted febrile myalgia and Behçet's disease (1, 3 ,8). Necrotizing crescentic glomerulonephritis with granulomatous vasculitis associated with FMF has not been described before. Although renal biopsy findings were strongly suggestive of Wegener's granulomatosis (WG), no other clinical, serological and radiological findings of WG or other systemic vasculitides were observed. Our patient showed a favourable response to moderate immunosuppressant treatment consisting of colchicine and azathioprine, and developed no other findings suggestive of extrarenal involvement of a systemic vasculitis during the two-year follow-up. We therefore consider that the renal findings of the present case, which mimick pauci-immune ANCA-related glomerulonephritis, may be a unique form within the spectrum of FMF-associated vasculitides. The pathogenesis of non-amyloid glomerular diseases and vasculitis in FMF is still unknown. An immune complex mechanism may play an important role including type II rapidly progressive glomerulonephritis, IgM and IgA nephropathy (3, 4). But absence of immunoglobulins and complement in the biopsy specimens of our patient does not support this hypothesis. Another possible explanation is the entrapment of these substances as a result of mesangial dysfunction in clearing and processing of immunologically-irrelevant macro-molecular aggregates (7). In conclusion, non-amyloid glomerular diseases should also be considered in the differential diagnosis of patients with FMF and renal involvement, especially when hematuria accompanies proteinuria. T h e contribution of vasculitis to the renal involvement in patients with FMF and its pathogenetic mechanisms remain to be elucidated.

Background: Environmental tobacco smoke (ETS) or passive smoke exposure is one of the most common preventable health hazards in the community. The risk of disease and death as a result of smoking is not limited to smokers; non-smokers are also at risk from exposure to SHS. Passive smoking has recently been implicated in the development of several systemic diseases. Aims of the study: The purpose of this study was to evaluate the effects of passive smoking on periodontal health status and on the salivary levels of alkaline phosphatase (ALP), lactate dehydrogenase (LDH) and creatine kinase (CK). Materials and methods: The study comprised of 25 nonsmokers and 22 passive smokers. Unstimulated saliva sample was collected from each subject for biochemical analysis of salivary enzymes. Periodontal parameters including: plaque index, gingival index, bleeding on probing, probing pocket depth and clinical attachment level were recorded. Results: statistical analysis revealed that ALP in saliva was higher in smoker than the non smoker group and there was significant difference in the salivary LDH and CK levels between smokers and non-smokers groups. Probing pocket depth (PPD) and clinical attachment level (CAL) score 1 was higher in passive smokers compared with non smokers, while there was decrease in the number of bleeding sites. Conclusions: Passive smoking has negative impact on periodontal health and can consider as risk factor for periodontal disease although further studies are needed. Salivary enzymes (ALP, LDH and CK) are considered as good biochemical markers of periodontal tissue destruction and can be used to evaluate the effect of passive smoking on periodontal health status.


Common millet (Panicum miliaceum L.) and foxtail millet, also known as Italian millet (Setaria italica P. Beauv.), are among crop grasses that in the Antiquity and the early Byzantine period were grown on a relatively large scale. Yet although the sources indicate that they were among popular crops, they were neither as widespread not as highly regarded by consumers as wheat and barley. Views pertinent to the dietetic doctrine with regard to those to plants evolved before Galen's lifetime and were very consistent, considering that they did not change over the period from the 2nd to the 7th century. This doctrine pointed to the less beneficial qualities of both these crop plants in comparison to the most highly values grains used in bread-making, especially to wheat. Also, common and foxtail millet were constantly present in the cuisine of the period in question, both being used as food in the rural areas rather than in cities. They were usually put in boiled dishes, because millet bread was unpopular owing to its brittleness and disagreeable taste. Both common and foxtail millet were included among the farmaka used in the period between the 2nd and 7th century, although they certainly were not as favoured in medicine as wheat and barley. Common millet was more often mentioned in the healing role. Both grains were used in medical procedures as components of healing diets, especially foods helpful in alleviating gastric disorders. Flour ground from common millet was applied as powder, whereas the grain itself found use as a component of warming cataplasms and poultices which usually had a drying quality. In addition, millet to was considered to be an efficacious antidote against poisons.


We study the Kahler potential of charged matter fields, whose profiles have a peak on their matter curve — on an "intersection" of 7-branes, in an F-theory compactification. It is shown that the Kahler potential is exactly given by the integral over the matter curve, but not by the integral over the whole GUT surface of 7-branes. This talk is based on our paper "A Note on Kahler Potential of Charged Matter in F-theory," in collaboration with Yoichi Tsuchiya and Taizan Watari.


Abstract The current study aimed to select the strains of lactic acid bacteria (LAB) isolated from forage cactus plants and silage and assess their effects on silage fermentation and aerobic stability. Forty wild isolates from plant and cactus silage, classified as LAB, were evaluated for metabolite production and identified by 16S ribosomal DNA sequencing. These wild isolates were identified as Lactobacillus plantarum, Weissella cibaria, Weissella confusa and Weissella paramesenteroides and the LAB populations differed among the silage. The use of microbial inoculants did not influence gas or effluent losses in forage cactus silage. The silage inoculated with the microbial strain GP15 showed the highest number of LAB populations. The amounts of water-soluble carbohydrates (WSC) and ammonia nitrogen differed among the silage. The silage inoculated with the GP1 strain presented the highest WSC. Populations of enterobacteria and yeasts and moulds were below the minimum detection limit (<2.0 log cfu/g silage) in all the silage studied. The predominant action of inoculants was to maximize dry matter recovery of the silage, which could be the criterion adopted to select the strains of LAB for use as inoculants in Opuntia silage.


With error-free diffraction data from the protein cytochrome c550 from Paracoccus denitrificans, having molecular weight Mr ≃ 14 500, space group P212121, and a single PtCl2-4 derivative, estimates (0 or π) of the three-phase structure invariants are obtained by recently secured direct methods employing the six-magnitude first neighborhood [Hauptman (1982). Acta Cryst. A38, 289-294] and compared with the known values. The comparison shows that these methods are capable of estimating reliably several tens of thousands of those invariants having the extreme values 0 or π, approximately. It is therefore anticipated that direct methods will play an increasingly important role in the determination of macromolecular structures.


The global error at any point in the step by step numerical solution of an initial value problem is the sum of local errors introduced at every step, each multiplied by an amplification factor due to the stability or instability of the differential equation. If these factors were unity (as, for example, in a quadrature problem) it is possible to keep the global error e(t) over the interval [a, b] less than Δ by keeping the local error in a step of length h less than hΔ/(b-a). This is called error per unit step. Unfortunately, theory shows that the error strategy which minimizes the amount of work for a given global error Δ is to make the local error equal to g(Δ) where, for a pth order method, g(Δ) = q(t)Δ(p+1)/P+ higher terms, and q(t) depends on the differential equation.
 The talk will present experimental evidence of the increased efficiency of error per step versus the smoother dependence of the global error on the error control parameter for error per unit step. The existing theory will be summarized, and the question of how the local error estimate can be justified theoretically will be examined.

We investigate the possibility to implement low-energy consuming binary logic gates by means of charge sensing in electrostatically defined quantum dots (QDs) formed in single electron transistors (SETs). In the proposed logic devices, the input signals are represented by the voltage levels at the SET's gate electrodes, and the output is determined by the electrical current in the charge sensor (CS) circuit. In contrast to previous proposals of SET-based logic, the output signal does not depend on the electrical current through SET, but is defined by its charge configuration in the Coulomb blockade regime. Such a logic implementation suppresses the shot noise without increasing energy consumption.


In this paper, a waveguide fllter using miniaturized- element frequency selective surface (FSS) is presented. The proposed FSS is composed of periodic array of metallic patches separated by small gaps and metallic lines. The array of patches constitutes a capacitive surface and the lines a coupled inductive surface, which together act as a resonant structure. At about 5.0GHz, a narrow bandpass response is designed. Dimensions of the FSS element are much smaller than the operating wavelength, which is less than 1=13'. For this miniaturized element, grating lobes are restrained and do not appear event to 25GHz. Moreover, the FSS has stable performances for various incident angles. Design procedure and measurement results of the FSS are presented and discussed.


This Article starts out by explaining why robust civil-military relations matter. Without meaningful and reliable civilian control of the military, governments lose some measure of control over the destiny of their nation. In extreme circumstances it can even lead an overthrow of government. Part I discusses "A More Perfect Military: How the Constitution Can Make Our Military Stronger" by Diane Mazur, a new book that examines recent civil-military relations in the United States. Her carefully constructed work maintains that since the Vietnam era, the United States Supreme Court has hewn the armed forces from general society in order to create a separate — and more socially conservative — sphere. Part II discusses "The Decline and Fall of the American Republic" by Bruce Ackerman, a wise and wide-ranging book which argues that the nation's polity is in decline and that the increasingly politicized armed forces may ultimately lead to a coup. Part III asks where we go from here. The important books under discussion attribute a thinning of the civilian control over the military to legal and political decisions made over the past thirty years. They explain some of the most critical implications of this transformation. And they offer sensible proposals about how to improve that critical relationship for the sake of enhancing the effectiveness of our armed forces and the vitality of our republic. But, neither work examines the evolving nature of great power politics since the end of the Cold War, the effects new technologies have on long-standing distinctions and borders, or the relative rise of non-state actors including al Qaeda — three sets of exogenous factors that inevitably drive changes in the civil-military relationship. So in the end, they point to a more ambitious enterprise, reexamining the relationship between force and twenty-first century society.


The result of the civil environment suit,which is involved in public interest,should meet the justice requirement of the parties and the society,so the civil environmental suit should be subject to exclusive jurisdiction.According to the Civil Procedure Law in force,the civil environmental suit is not subject to exclusive jurisdiction,but actually it is.During amending the Civil Procedure Law,we should correctly stipulate the territorial jurisdiction of civil environmental suit.

Abstract In the industrially advanced societies of the West, economic development has invariably been accompanied by a structural shift of labor from the primary and secondary production Sectors to the tertiary or service sector. A systematic analysis of the service sector would show that the "commodity" on which this sector acts is "information." The increasing importance of "information" for control and management in an "advancing" society is the primary reason for the structural shift of labor to the service sector. In this paper the critical importance of the service sector to development is emphasized and it is argued that information technology that underpins activity in this sector is an appropriate technology for speeding‐up socioeconomic development in the third world countries.


An electric machine comprises a rotor, preferably having permanent magnets, although other field generation means are available, and a stator. The stator has coils wound on stator bars for interaction with the magnetic field of the rotor across an air gap defined between them. The rotor comprises a housing of a chamber containing refrigerant. The rotor housing has heat dissipating fins accessible by the open environment whereby air movement relative to the housing caused at least by rotation of the rotor absorbs heat from the fins. The machine may be an axial flux machine, the coils being wound on bars that are disposed circumferentially spaced around a fixed axle of the machine forming a rotational axis of the rotor. The machine may be a wheel motor for a vehicle, wherein the wheel is mounted directly on the rotor housing.

A series of randomized studies have revealed comparable long-term results for both laparosopic and open resections in the treatment of renal and colonic neoplasms. From a purely oncological perspective, the benefit-detriment debate regarding synchronous laparoscopic resections remains a hotly disputed issue and continues to face scrutiny in today's medical community. However, although this debate has become an important issue, there are few reports in mainstream literature discussing the simultaneous laparoscopic resection of renal and colorectal carcinomas. This report overviews two entirely laparoscopic procedures: a simultaneously performed right nephrectomy and left colectomy and a simultaneously performed left nephrectomy and left colectomy. The laparoscopic technique for simultaneous abdominal primary malignancy has proven to be safe, effective, and practicable. This paper will overview the authors' experience with such procedures, outlining technical setbacks in the course of surgery and discussing the overall results of the operations.


Unmanned surface vehicles (USVs) often execute missions in highly dangerous and complex environments, making it difficult to maintain once critical failure occurs. Therefore, this paper aims to propose a prognostics and health management (PHM) system framework for USVs to satisfy the requirements for real-time fault monitoring, health-state evaluation, and preventive maintenance. A functional structure framework is proposed on the basis of USVs PHM system requirement analysis. The method of implementing the real-time health-state evaluation of the USVs is summarized through the case study of navigation radar. Thereafter, the multi-method modeling is used to simulate the failure of key components of the USVs system, and the mission capability simulation model is constructed, which lays a foundation for the realization of the USVs PHM system.


To ascertain the existence of a・suPerlattice in the composition CuAu3, we carried out investigations with several al!oys of compositions rtear 75 at% Au by means of calorimetric, resistometric, dilatometric and X-ray methods. We have succeeded in showing clearly the presence of superstructure lines on the microphotometer curve of X-ray diffraction photographs of the annea!ed alloy. For the ordered alloy (74 at % Au), the specific heat-temperature curve shows a A-type peak at 2430C. Since the rate of ordering of CuAu3 alloy is very slow,the highly ordered state was obtainable oniy after the specimen had been annealed at about 1800C for 1 month. The transition energy was estimated to be 290 cal/mol, the accompanying entropy change being about O.32 R. Variation of electrical resistjvjty with temperature shows an anomalous behaviour, that is,`it rises at the onset of order. This result seems to be inconsistent with the usual concept of order-disorder transformations, but perhaps it may be explained by the lattice distortions in the highly ordered state due to the jnequality of the atomic radii between two component elements.


In this article we present a technique which helps students in understanding proofs in the context of automata theory. The main conclusion is that student understanding can be improved by using a collection of lemmas and trying to automate the proof in a mechanical theorem prover.


This paper presents a novel substitution matrix loader architecture for pairwise sequence alignment. The search for sequence homology using DP-based alignment matrix computation is an important tool in molecular biology. It can be implemented either by optimal or sub-optimal approaches. Both of these methods require frequent and rapid access to the amino acids probability scores for PE (Processing Element) configuration especially in a folded systolic array. Typical FPGA implementations configure look-up tables in the pipeline PEs either by using a serial configuration chain with different look-up tables or by run time reconfiguration of the same look-up table. In the former case, configuration time increases proportionally to the number of look-up tables, while the latter case suffers from the limited reconfiguration bandwidth. Therefore, in this paper, we propose a highly efficient parallel loader to optimize both time and space complexities of protein sequence alignment in folded systolic arrays, using only two configuration elements (CEs). In addition, the proposed loader enables PEs to be updated with substitution matrix scores concurrently, with the worst case configuration time of 2 × the depth of the PE's look-up table (in clock cycles). This allows for further optimization of the most time consuming alignment matrix computation through efficient scheduling of alignment matrix computation and PE configuration. Implementation results show that the proposed architecture achieves k.NPE speed-up in configuration time (where k is the folding factor and NPE is the number of PEs) compared to classical approaches, at virtually no area overhead.


Background subtraction plays an important role in intelligent video surveillance since it is one of the most used tools in motion detection. If scientific progress has enabled to develop sophisticated equipment for this task, algorithms used should be improved as well. For the past decade a background subtraction technique called ViBE is gaining the field. However, the original algorithm has two main drawbacks. The first one is ghost phenomenon which appears if the initial frame contains a moving object or in the case of a sudden change in the background situations. Secondly it fails to perform well in complicated background. This paper presents an efficient background subtraction approach based on ViBE to solve these two problems. It is based on an adaptive radius to deal with complex background, on cumulative mean and pixel counting mechanism to quickly eliminate the ghost phenomenon and to adapt to sudden change in the background model.


TV news is art of vision, it is limited by time, they must be true and press close to live. The report in 16th National Congress of CPC brings forward that the CPC hold high the banner of Marxism, Mao Zedong Thought and Deng Xiaoping Theory, it is the banner of "Three Representatives" , as the mouthpiece of the Party and the people, should shoulder political duty and historical mission. We must round closely the theme and objective that brings forward in 16th National Congress of CPC, develop with time, build a best atmosphere of public opinion, to carry out "Three Representatives


Recent survey of the epilithic diatoms in the running waters of Reunion Island led to the discovery of a new species of Achnanthidium . Achnanthidium palmeti sp. nov . belongs to the group of Achnanthidium taxa with terminal raphe fissures curved to the same side of the valve. The new species differs from other taxa in this group by a higher stria density and the areolae morphology along the axial area; moreover, apart from Achnanthidium latecephalum H. Kobayasi, A. palmeti sp. nov . is the only species having raphe vestiges. The new species was found in oligotrophic waters with very low conductivity and circumneutral pH.


An investigation has been conducted to determine the aerodynamic characteristics of a large-scale subsonic jet transport model with an externally blown triple-slotted flap. The lift of the model was augmented by the turbofan engine exhaust impingement on the flap surface. The model had a 25 deg swept wing of aspect ratio 7.28 and four turbofan engines. The model was tested with two flap extents. One extended from 0.11 to 1.00 of the wing semispan, and the other extended from 0.11 to 0.75 of the wing semispan with a single-slotted aileron from 0.75 to 1.00 of the wing semispan. The results were obtained for several flap deflections with and without the horizontal tail at gross thrust coefficients from 0 to 4.0. Longitudinal and lateral data are presented with three and four engines operating.


We show that thin accretion disks made of carbon or oxygen are subject to the same thermal ionization instability as hydrogen and helium disks. We argue that the instability applies to disks of any metal content. The relevance of the instability to supernova fallback disks probably means that their power-law evolution breaks down when they first become neutral. We construct simple analytical models for the viscous evolution of fallback disks to show that it is possible for these disks to become neutral when they are still young (ages of a few 103 to 104 yr), compact in size (a few 109 to 1011 cm) and generally accreting at sub-Eddington rates ( ~ a few 1014-1018 g s-1). Based on recent results on the nature of viscosity in the disks of close binaries, we argue that this time may also correspond to the end of the disk activity period. Indeed, in the absence of a significant source of viscosity in the neutral phase, the entire disk will likely turn to dust and become passive. We discuss various applications of the evolutionary model, including anomalous X-ray pulsars and young radio pulsars. Our analysis indicates that metal-rich fallback disks around newly born neutron stars and black holes become neutral generally inside the tidal truncation radius (Roche limit) for planets at ≈1011 cm. Consequently, the efficiency of the planetary formation process in this context will mostly depend on the ability of the resulting disk of rocks to spread via collisions beyond the Roche limit. It appears easier for the merger product of a doubly degenerate binary, whether it is a massive white dwarf or a neutron star, to harbor planets because its remnant disk has a rather large initial angular momentum, which allows it to spread beyond the Roche limit before becoming neutral. The early super-Eddington phase of accretion is a source of uncertainty for the disk evolution models presented here.


PURPOSE
Amateur singing is a universal, accessible, and enjoyable musical activity that may have positive impacts on human communication. However, evidence of an impact of singing on speech articulation is still scarce, yet understanding the effects of vocal training on speech production could provide a model for treating people with speech deficits. The aim of this study was to examine speech production in younger and older adults with or without amateur singing experience.

METHOD
Thirty-eight amateur singers (aged 20-87 years, 23 women and 15 men) and 40 nonmusician active controls (aged 23-88 years, 19 women and 21 men) were recruited. A set of tasks were used to evaluate the oral motor sphere: two voice production tasks, a passage reading task, and a modified diadochokinetic (DDK) rates task performed at a natural rhythm and as quickly as possible.

RESULTS
Our results show that older age was associated with lower reading rate, lower articulation rate, and articulation rate variability in the DDK task, as well as reduced accuracy for the phonologically complex stimuli. Most importantly, our results show an advantage for singers over cognitively active nonsingers in terms of articulatory accuracy in the most challenging situations.

CONCLUSION
This result suggests extended maximal performance capacities in amateur singers perhaps resulting from the articulatory efforts required during singing.

The data recorded by airborne high resolution imaging spectrograph are large and the accuracy of common compression method cannot fulfil the requirements of the post processing.For this reason the image will be analyzed into different frequency domains and by means of wavelet transform,then they will be coded and compressed according to multi spectral image,thus the compression can be carried out in a better way.Compared with the common compression method,this method will not appear fuzzy case and has a higher accuracy.


The effects of oral administration of Viscum album (Family Loranthaceae) and Nigella sativa (Family Ranunculaceae) extracts on some immune responses of Cyprinus carpio were studied. Four hundred and fifty fish weighing 108±11.4 g were divided into two groups for immune and non-immune treatments. For immune treatment the fish were injected with Aeromonas hydrophila bacterin and the non-immune treatment received sterile phosphate buffer saline. Each treated group was divided into three treatments: Fish in treatments 1 and 2 were fed a diet supplemented with 0.5% (w/w) V. album or N.sativa extracts respectively while in treatment 3 fish were fed a free extract diet. Fish in all treatments were fed for 30 days. Blood samples were taken every 10 days and hematoimmunological indices were compared among treatments. Results showed that oral administration of V. album and N. sativa extracts were able to enhance lysozyme activity, serum bactericidal activity, serum protein and serum globulin in immunised and nonimmunised groups (P<0.05) but complement activity showed no significant change among groups (P>0.05). Resistance to A. hydrophila infection was significantly higher in immunised fish treated with V. album. However, N. sativa did not reduce mortality following the challenge with bacteria. This study indicates that oral administration of V. album extract is a potential candidate for herbal based immunostimulants in common carp.

This PhD thesis is devoted to the engineering of quantum coherence in the integer quantum Hall effect regime (IQHE) at filling factor ν=2, obtained by applying a strong perpendicular magnetic field to a bidimensional electron gas formed at the interface of a GaAlAs/GaAs semiconducting heterostructure. Then unidimensional chiral conductors called edge states appear which can be used as electron beams to build the equivalent in condensed matter of a Mach-Zehnder interferometer (MZI) so as to study coherence in this regime. The unexpected periodic lobe structure of the visibility as function of the bias voltage suggests that interactions play an important role.In the first part, we explain how edge states emerge in the IQHE regime. We picture the state of the art on the edge states coherence. Then we present the MZI from the experimental point of view.Next we show our results, first concerning the visibility at finite bias: our measurements confirm a prediction about a quantum phase transition as function of the interfering edge state dilution. We don't see any significant manifestation of energy relaxation in the visibility. Finally, having identified the adjacent edge state as the noisy environment limitating coherence thanks to previous works, we have designed a new kind of sample to decrease the coupling of the system to this environment in a controlled manner. We thus decreased dephasing by half, in quantitative agreement with the theory developped previously in our group.


Abstract The three disaccharides, 4-O-β-D-glucopyranosyl-6-deoxy-D-glucose (Glc-6-deoxy-Glc), 4-O-β-D-glucopyranosyl D-mannosamine (Glc-ManN), 4-O-β-D-glucopyranosyl-D-mannose (Glc-Man), were synthesized from equimolar amounts of 6-deoxy-glucose and α-D-glucose-1-phosphate (G-1-P), D-mannosamine and α-D-glucose-1-phosphate (G-1-P), and D-mannose and α-D-glucose-1-phosphate (G-1-P), respectively, using cellobiose phosphorylase from Cellvibrio gilvus. The yields were 60%, 10% and 50% based on the initial amounts of 6-deoxy-D-glucose, D-mannosamine and D-mannose, respectively. The structures of disaccharides were confirmed by NMR and mass spectroscopy analysis.


Nanometrics' Pegasus digitizer is the basis for a scientific grade node and is the latest development in many years of designing and building reliable seismic instruments for the scientific and monitoring community. Coupled in a grab-and-go quick deploy package with a variety of sensors enables responses to many types of events and environmental measurements. These types of systems are not only for hazards, such as earthquakes and volcanoes, but can form the basis of better tools used for critical structure and microzonation studies using ambient noise.  Pegasus takes advantage of a complete ecosystem of software, making planning, deploying and data harvesting very simple and straightforward as well as providing a dataset that includes automatically generated metadata in the form of StationXML and standard miniSEED data files.  Pegasus design criteria was based on optimal SWaP (Size, Weight and Power) and makes it unique in short to long duration deployments without swapping of units in the field, while its broad sensor compatibility enables many types of measurements and is completely compatible with the advantages of Nanometrics smart sensors.


Uniform-sized carbon microspheres with diameters of several hundreds of microns and adjustable mesopore structure were obtained from poly(furfuryl alcohol)–silica (PFA–SiO2) microspheres. The PFA–SiO2 composite microspheres were synthesized via the phase transfer of FA and the subsequent polymerization in aqueous silica sol droplets formed in a simple microfluidic device, followed by carbonization and HF etching to remove the silica template. It was found that the resultant carbon microspheres were mesoporous, and their mesoporosity depended on the flow rate of the oil phase and the residence time of the microdroplet in the device during the preparation of PFA–SiO2 microspheres. The carbon microspheres exhibited heterogeneous structure with submicron-sized ball-like carbon particles embedded in the smooth carbon matrix. The highest mesoporous volume and mesoporosity of carbon microspheres reached 1.10 cm3 g−1 and 85%, respectively, and the mesopores were in the range of 2–20 nm. Mesoporous silica microspheres embedded with submicron-sized cavities could also be prepared by burning-off the carbon in the carbon–SiO2 microspheres.


Brookhaven National Laboratory is now in the process of expanding the capability of the AGS to include the acceleration of polarized protons. One of the requirements to accomplish this is to pulse twelve quadrupole magnets to rapidly cross depolarizing resonances. Having crossed the resonance, the field in the magnet must be maintained so as not to re-cross the resonance. The problem is addressed with two mirror image circuits, one to produce positive pulses, and the other negative. Each of these circuits are further divided into two sections, one to cause the rapid rise, and the other to maintain the slow fall.


Autonomy is one of the key concepts in transactional analysis. A six-year research project in the Netherlands offers new indications of what this concept really means. Factor analysis was used to look for confirmation of Berne's hypothesis—that autonomy is manifested in the person's capacity for awareness, spontaneity, and intimacy—as well as the suggestion by other authors who added a fourth capacity: responsibility. The results show a different and interesting outcome. The data provides a powerful indication that autonomy is nothing more (or less) than good contact.


Genetic Programming (GP) is an evolutionary technique that evolves computer programs to solve a problem. GP is commonly used for classification tasks where an input must be classified into a single category. The use of standard binary operators has proven effective for classification, but recent research has found that loop structures can generate notably better results. It is still unclear how characteristics of loop structures affect different classification tasks. This research proposes five novel loop structures with different characteristics and analyses their effectiveness and understandability against both image and nonimage classification tasks. Results find that the proposed loop structures can outperform GP with no loops and existing loop structures. Results are also simpler and more human understandable than GP with no loops and existing loop structures.


We describe several strategies for the molecular design of high-efficiency blue fluorescent emitters. Asymmetric donor–acceptor (D–A) and symmetric A–D–A-type fluorescent emitters were designed with spiroacridine donors and diphenyltriazine acceptors. Substituting a toluene or xylene moiety for the phenyl group connecting the donor and acceptor and replacing the diphenylsilane group with a fluorene moiety resulted in a deeper blue emission without any losses in luminescence efficiency. On the basis of these substitutions, deep blue organic light emitting diodes (OLEDs) with Commission Internationale de L'Eclairage (CIE) coordinates of (0.149, 0.082) and an external quantum efficiency (EQE) of 7.7% were fabricated using a D–A-type emitter. Symmetrizing the D–A structure to an A–D–A structure increased the proportion of horizontally oriented emission dipoles in the organic film from 70 to 90%. OLEDs incorporating symmetric A–D–A-type emitters had EQEs as high as 8.5% due to increased outcoupling efficiencie...
