Ultrasonic velocity (U), viscosity (h) and density (ρ) of lactose of (0.5m) in three aqueous electrolytic solutions of guanidine hydrochloride (GuHCl), barium chloride (BaCl2) and strontium chloride (Sr Cl2) have been measured at 298.15 K. The derived acoustical parameters namely adiabatic compressibility (b), apparent molal compressibility ( K j ), apparent molal volume ( V j ), limiting apparent molal compressibility ( 0 K j ), limiting apparent molal volume ( 0 V j ), and their constant (SK, SV), viscosity B–coefficient and hydration number (nH) have been computed from the experimental data. The variation of these parameters with respect the molality of solute has been discussed in terms of solute-solvent and solute-co-solute interactions


Cyber-trafficking is the illegal transport of humans, drugs, weapons, or goods by means of Internet-enabled electronic devices. Currently, there is a lack of surveillance and understanding of the rapidly growing social concern about cyber-trafficking (CT). This paper describes the Cyber-Trafficking Surveillance System (CyTraSS) and provides preliminary findings of using the system to monitor CT social media discussions. CyTraSS supports flexible collection, analysis, and visualization of social media content, user linkage, and temporal features. The CyTraSS database contains a focused collection of over 2,318,691 social media messages posted by over 740,070 users who discussed about trafficking crimes and issues. CyTraSS supports keyword search, sentiment analysis, message statistics summarization, and influential leader identification. Emotion expressed in social media messages is extracted and aggregated quantitatively to indicate community mood. We examined three use cases about a sex trafficker identified by a flight attendant, Federal use of private prisons, and trafficking cases related to Beijing. These time-sensitive incidents are highly-relevant to CT and were identified by using clues provided by CyTraSS. The results have strong implications for understanding CT concern on social media.

Calcined coal gangue was used as active addition of magnesium phosphate cement (MPC). Influence of calcined coal gangue addition on the setting time, mechanical property, mineral phase, and microstructure of MPC had been studied. The prescription was designed as following: the ratio of mono ammonium phosphate to magnesia was 0.25 in mass, additive amount of calcined coal gangue was 0%, 10%, 20%, 30%, 40% to the total mass of magnesia and mono ammonium phosphate respectively, borax additive amount was 0.06 to other raw materials. The result show that calcined coal gangue could extend the final setting time and improve the early strength of MPC. The MPC obtained its maximum compressive strength of 94.9 MPa and 95 MPa with the calcined coal guage content is 0% and 10% respectively. The particles of calcined coal gangue powder filled in the voids of cement matrix as framework and had effect on microstructure. Furthermore, calcined coal guage might participate the hydration reaction in a long age and form a cementing product which result in improvement of MPC's long time strength.


During a developmental critical period, juvenile male zebra finches learn to sing a highly stereotyped song from a tutor bird. Song learning in zebra finches shares many common behavioral, physiological, and neuroanatomical features with other nervous systems that exhibit critical periods. These include development of binocular vision in cat, formation of sensory maps in rodent, and acquisition of language in humans. One important regulatory principle summarized from the various systems is the experience-dependent structural remodeling within the associated brain areas. The brain area HVC, which is the vocal motor cortex analog in the zebra finch brain, plays a crucial role during song learning in juveniles and actively drives production of the learned song in adulthood. Similar to the structural remodeling that has been observed in primary visual cortex (V1) in cat and barrel cortex in rodents, dendritic spines in HVC undergo rapid remodeling in response to critical sensory experience. However, the mechanisms underlying the experience-dependent remodeling at the synaptic level are unclear. In particular, the HVC inhibitory circuit, which is shown to be crucial for song learning, has not been studied anatomically at the synaptic level yet. And the experience-dependent structural changes in HVC has not been carefully decoupled from developmental structural changes. Therefore, I set out to carefully study the structural synapse changes in HVC during song development. I propose two experimental approaches to investigate the open scientific questions described above. The first experiment was inspired by an in vivo imaging study, which reported initial sensory experience of the tutor song triggered spine stabilization and enhancement overnight in HVC in juvenile zebra finches (Roberts et al. 2010). I further investigated this experience-dependent structural remodeling in HVC in two ways. First, I further manipulated the song sensory experiences in juvenile zebra finches. In different groups of juveniles, I provided short, long, or no tutor exposure, and then harvested their HVCs for neurostructural analysis at the same age. I then examined HVC further with serial-section and block-face electron microscopy, which allowed me to directly and clearly identify, classify, and morphologically reconstruct HVC synapses. The results showed synaptic pruning, and suggested synaptic strengthening in HVC excitatory synapses in a song sensory experience-dependent manner, which was in agreement with previous findings. Surprisingly, the results also suggested a transient density increase of the inhibitory synapses in HVC, following one day of tutor song sensory exposure. Rapid experience-dependent remodeling of the inhibitory circuit in HVC has not been reported before, but similar has been observed in the mouse somatosensory cortex (Knott et al. 2002). Taken together, these results indicate that tutor song exposure


From the perspective of the sociology of professions, every professional activity should have its own clearly circumscribed and regulated sphere of action. Such an articulation facilitates the regulation of the production of a given profession as well as the way in which it is practiced. The purpose of the research reported here was to provide a comprehensive review and evaluation of the regulatory framework governing the advertising sector in Spain.

ABSTRACT The South China block (SCB), located in the convergence zones of the western Pacific subduction tectonic domain and Tethyan tectonic domain, has experienced complex tectonic processes, including the continent–continent collision caused by the closure of the Palaeo-Tethys Ocean, and the subduction of the Palaeo-Pacific plate. However, due to complex intracontinental deformation and abundant magmatism, there are serious divergences in the corresponding records of the tectonic transformation from Palaeo-Tethys to Palaeo-Pacific. We have analysed the map-scale superimposed fold system developed in central SCB and also inverted the palaeo-stress field based on the fault–slip vectors. On this basis, the deformation styles and superposition mechanism of two-stage folds were recovered to establish the tectonic stress field in early Mesozoic and tectono-magmatic events by combining the chronology of the accompanying syntectonic magma. The early E–W/WNW-trending folds and Triassic magmatic system were identified; these were controlled by the NE–SW-trending compressive stress field, to coordinate with the collisions between the SCB and the Indochina block in the southwest, and the North China block in the north. The late NE/NNE-trending folds superimposed on the early folds in an orthogonal way to form a large-scale dome-basin superimposed fold system, which were controlled by the WNW–ESE-trending compressive stress field. According to the strata relations involved in deformation and the chronology data of magmatic rocks, it could be determined that NE/ENE-trending folds would be formed during the Mid- to Late Jurassic, corresponding to the westward subduction events of the Palaeo-Pacific plate. The establishment of the large-scale superimposed fold styles and the identification of fold deformation in the Triassic and Jurassic are important for understanding the early Mesozoic tectonics of South China, and even for all East Asia continent. In particular, it can provide important temporal and spatial constraints to explain the complex deformation process and geodynamic settings of South China in the early Mesozoic.


In this paper, we describe the participation of the Advanced Data Analysis and Management (ADAM) group of the University of Feira de Santana in the Bots and Gender Profiling Task organized by PAN@CLEF 2019. We used Support Vector Machines (SVM) optimized through nested cross-validation. In bot detection, we used features related to behavior of the account, sentiment and variety of posts, in gender detection function words and emoticons. These features were evaluated both individually and in groups. Before starting the training phase, we preprocessed the data to better adjust it. For bot detection, our method reached approximately 0.9057 for English and 0.8767 for Spanish. For gender detection, 0.7696 for English and 0.7150 for Spanish. Although the results for Spanish are poorer than the ones for English, they are above the random baseline (50%).


The effects of light, temperature, and thyroxine on the proportions of two visual pigments (rhodopsin and porphyropsin) are compared for three species of fishes in which the pigment proportions change oppositely in response to light (rainbow and brook trout vs. common shiners). In rainbow trout and common shiners higher temperatures reduced the proportions of porphyropsin in the retina, independent of photic conditions. The greatest differences between the warm and cold treatment groups, however, were obtained with a photoperiod as contrasted with continuous light or darkness. Capping of one eye in brook trout reduced porphyropsin independently of the uncapped eye. Thyroxine, which favors porphyropsin in both species groups, acted effectively only in the presence of light. It is suggested that a photoperiod, which produces both bleaching and photomechanical movements within the retina, enhances the exchange of vitamin A1 and A2 aldehydes between the photoreceptor cells and the pigment epithelium. Apparent...

The objectives of the study are to reveal whether or not there is a significant correlation between students' interest in reading scientific essays, scientific vocabulary mastery and their achievement in reading comprehension.
 The writer stated the working hypothesis of the study as follows: "There is a significant correlation between students' interest in reading scientific essays, scientific vocabulary mastery and their achievement in reading comprehension." The hypothesis was changed into null hypothesis that is "There is no significant correlation between students' interest in reading scientific essays, scientific vocabulary mastery and their achievement in reading comprehension". The research methodology used was descriptive statistical study. To collect the data, the writer used a questionnaire and a set of tests.
 After getting the score of the students' interest and the scores of the vocabulary mastery and the score of their achievement in reading comprehension, the data were statistically computed to find out the correlation between three variables.
 The result, both the students' interest in reading scientific essays and scientific vocabulary mastery have significant correlation with their achievement in reading comprehension. The value of correlation coefficient R is 0.571 or 57.1%. It means that both the students' interest in reading scientific essays and scientific vocabulary mastery influence their achievement in reading comprehension.
 Based on the result of the experiment, the writer suggested that in teaching reading, the lecturers should train the students with a lot of practice in reading scientific essays and scientific vocabulary mastery. On the other hand, students should read scientific essays as much as possible to enrich their knowledge.


AbstractMeasurements of ionospheric absorption were carried out at Ahmedabad (latitude 23°0'N., longitude 72°6'E.) on 2·5 mc./s., using vertical pulsed transmission during the period August 1957 to July 1958. The strength of the transmitted signal was kept constant and the intensities of the vertically reflected pulses were cut down by the use of a passive attenuator so as to give a constant intensity of signal on the oscilloscope screen of the receiving circuit.It was found that the mean monthly values of the absorption plotted against cos χ for each month from August 1957 to July 1958 obeyed a relation of the type log ρ α cosnχ. The value of 'n' for individual months ranges from 0·64 to 0·89 and the mean value is 0·73. To eliminate the effects of the seasonal changes in the noon zenith distance of the sun, the values of absorption for cos χ = 1 were obtained by extrapolation. These extrapolated values show a fairly close correlation with the sunspot number.Generally the maximum absorption is reached som...


Joint application development (JAD) techniques are generally viewed as a way of improving the quality of applications and the efficiency of the development process. Yet the facilitated group approach that forms the basis of JAD methodology is useful for empowering employees and managing group work across a broad range of organizational decision-making and systems development tasks. Extending the benefits of JAD to these tasks increases the strategic competitiveness of both the IS department and the larger organization.


This paper presents a new method to monitor magnetic saturation level of a synchronous generator operating in an electric power system. The proposed method makes use of air-gap permeance distributions, which can be derived from air-gap flux distributions measured by a search coil wound around a stator tooth of a generator. Tests were conducted on a laboratory-model power system to verify the validity of the proposed monitoring method. Test results under various operating conditions are presented to show a wide range of change in saturation level inside the generator. Its effects on generator performance in the power system and the benefits of the monitoring method are also discussed. >

Based on the SEIR model, which takes into account prevention and control measures, prevention and control awareness, and economic level and medical level indicators, this paper proposes an infectious disease model of "susceptible-exposed-infected-removed-asymptomatic-isolated" (short for SEIR-AQ) to assess and predict the development of the COVID-19 pandemic with different prevention and control strategies. The kinetic parameters of the SEIR-AQ model were obtained by fitting, and the parameters of the SEIR-AQ model were solved through the Euler method. Furthermore, the effects of different countries' prevention and control strategies on the number of infections, the proportion of isolation, the number of deaths, and the number of recoveries were also simulated. The theoretical analysis showed that measures such as isolation for prevention and control and medical tracking isolation had a significant inhibitory effect on the development of the COVID-19 pandemic, among which stratified treatment and enhanced awareness played a key role in the rapid regression of the peak of COVID-19-infected patients. Conclusion of the Simulation. The SEIR-AQ model can be used to evaluate the development status of the COVID-19 epidemic and has some theoretical value for the prediction of COVID-19.


Abstract : Disc carving is an essential element of computer forensic analysis. However the high cost of commercial solutions coupled with the lack of availability of open source tools to perform disc analysis has become a hindrance to those performing analysis on UNIX computers. In addition even expensive commercial products offer only a fairly limited ability to "carve" for various files. In this thesis, an open source tool known as Foremost is modified in such a way as to address the need for such a carving tool in a UNIX environment. An implementation of various heuristics for recognizing file formats will be demonstrated as well as the ability to provide some file system specific support. As a result of these implementations a revision of Foremost will be provided that will be made available as an open source tool to aid analysts in their forensic investigations.


Photovoltaic thermal (PV/T) system was introduced to meet the thermal and electrical energy. The heat removal by air or water prevents the deterioration of the PV cell efficiency due to the overheating of cells. In this study, an air type single pass PV/T collector system was proposed where a number of thin rectangular fins were introduced for heat dissipation. The collector's performance was analyzed with a fin system that was integrated by a thin flat metallic sheet (TFMS). Then, the temperature parameters were measured and compared to several operating conditions and configurations. Analytical expression was derived from the energy balance equations for each component of the design. Average temperatures from the top/rear PV surfaces, the collector back wall surface and the collector inlet/outlet temperatures were experimentally recorded under different fin numbers (0–4), mass flow rates (0.02 kg/s–0.14 kg/s) and solar radiations (200 W/m2–700 W/m2). These readings were used in calculating the thermal and electrical efficiency of the proposed PV/T system. The maximum thermal efficiency and PV efficiency ooling fin were obtained about 56.19% and 13.75% respectively for four fins at 0.14 kg/s of mass flow rate and 700 W/m2 of solar radiation. Besides, the root mean square percentages of deviation (e) and coefficient of correlation (r) were used to validate the result while also discussing the uncertainty values. This research will be helpful to design thermal collectors and provide valuable information regarding performance improvement methods in PV/T systems. © 2016 Elsevier B.V. All rights reserved.


In this paper we propose SkyCell, a prototyping platform for 5G autonomous aerial base stations. While the majority of work on the topic focuses on theoretical and rarely implemented solutions, SkyCell practically demonstrates the feasibility of an aerial base station where wireless backhaul, autonomous mobility and 5G functionalities are integrated within a unified framework. We showcase the advantages of Unmanned Aerial Vehicles for 5G applications, discuss the design challenges, and ultimately propose a prototyping framework to develop aerial cellular base stations. Experimental results demonstrate that SkyCell not only supports heterogeneous data traffic demand and services, but also enables the implementation of autonomous flight control algorithms while improving metrics such as network throughput (up to 35%) and user fairness (up to 39%).

Universal primer( L1490,H2198) and specific primer( Pat,Jerry) were used for cloning the mitochondrial cytochrome C oxidase I( COⅠ) gene fragments of four common scarabs. The homologous sequences were compared and partial nucleotide sequences of COⅠ( 689 bp,775 bp) obtained. The genetic distances of these sequences were analysed and the sequences used to produce three kinds of phylogenetic trees. The results show that the stability and differentials of interspecific distance of the sequences amplified with specific primers are clearly higher than those of sequences amplified with a universal primer. The phylogenetic trees constructed from sequences amplified with the specific primer are more consistent with the current morphological taxonomy of these scarab species. We conclude that sequences amplified with specific primer are more accurate for scarab classification.


The active-filter is one of the most efficient methods to improve power factor. However, this method has problems such as increasing switching loss and switching noise.This paper describes a new power factor correction (PFC) converter called "Partial-switching PFC", which achieves power factor rate of 99% only by generating a single pulse in the power line cycle with high efficiency and low total harmonic distortion. Its application to our air-conditioners is described at the end.

The results of optimization are planned to be used for producing mesh filters by LIGA-technology developed in the Siberian Synchrotron Radiation Centre.


Abstract We give upper bounds for the order of the elements in a characteristic set of a regular differential ideal or a radical of a finitely generated differential ideal with respect to some specific orderings. We then show how to compute characteristic sets of these ideals using algebraic methods.


Increasing grain protein concentration in maize (Zea mays L.) has not been a major focus of most breeding programs, which mainly focus on yield, maturity, and resistance to stress. The objective of this study was to evaluate the effectiveness of three cycles of mass selection to improve simultaneously yield and grain protein in the maize population GR-OP-319, derived from the F 2 generation of the single-cross hybrid PX-95. The two-step selection procedure involved a stratified mass selection system that included check plants for environmental control. In the first step, plants having grain yield higher than 80% of the check-plant mean and protein concentration greater than the check-plant mean were selected. In the second step, the four plants within each selection grid having the highest protein concentration were selected, which resulted in a final selection intensity of 5%. Three cycles of selection were completed during 1991 to 1995. Response to selection was evaluated during the selection process and by direct field evaluation of the C 0 , C 1 , C 2 , and C 3 populations in 1995 and 1996. The average response during the selection was 5.1% cycle - 1 for yield, 0.8 g kg -1 cycle -1 for protein concentration, and 7.0% cycle -1 for protein yield. No measurable differences among cycles were observed in the direct field evaluation even though the trends in the means of the cycles followed the trends shown during selection. After three cycles, the mass selection system studied did not appear to be particularly effective.

Wheat stripe rust is caused by Puccinia striiformis f.sp. tritici. It adversely affects the yield and quality of wheat grain. Seeds produced from stripe rust damaged crop have low vigour and poor emergence following germination. Stripe rust pathogen can cause 100% yield losses in susceptible cultivars if stripe rust occurs at an early stage and the infection continues to develop during wheat's growth. Stripe rust has caused yield losses ranging from 10-70% in most areas of wheat production (Chen, 2005). The wide range of yield losses depend on the susceptibility of wheat cultivar grown, timing of the initial infection, rate with which stripe rust develops and duration of stripe rust infection (Chen, 2005). Wheat rusts can either be controlled by spraying chemical fungicides or by developing resistant varieties. Fungicides are expensive, environment non-friendly and need to be applied at a specific growth stage. On the other hand, development of resistant varieties is relatively inexpensive and environment friendly method of controlling rusts. This, however, requires identification of resistant sources to be used as parents in breeding programs. Identification of yellow rust resistance genes and breeding of stripe rust resistant wheat varieties is an efficient approach to minimize wheat yield losses due to stripe rust (Ma et al., 1999). Therefore, wheat breeders and pathologists emphasizes on the development of high yielding and stripe rust resistant wheat varieties in order to combat threats created by new stripe rust races through incorporation of durable rust resistance with the help of marker assisted breeding. Presently, 48 stripe rust resistance genes (designated as Yr1Yr48) and several undesignated genes have been identified (McIntosh et al., 2010; McIntosh et al., R. A. 2008). Most of the identified Yr genes confer resistance to specific stripe rust races at seedling stage. Race-specific Yr genes confer shortlived and non-durable resistance in the field due to the evolution of new virulent races of stripe rust (Kilpatrick, 1975). Deployment of multiple stripe rust resistance genes can broaden the genetic base of future wheat cultivars against stripe rust fungus. Marker assisted selection is a useful tool in combining multiple Yr genes in a single genotype and in the development of multi-line cultivars having durable rust resistance. Microsatellites or simple sequence repeats (SSRs) are DNA sequence repeats of 1-6 base pairs. They are abundant in eukaryotic genomes and have been commonly used to facilitate identification and incorporation of durable resistance genes of various diseases in wheat (Gupta et al., 1999). Bulos et al. (2006) screened 88 Argentinian wheat cultivars with marker Ventriup-LN2 for the presence of Lr37/Yr17/Sr38 gene complex. Wang et al. (2009) screened 226 wheat cultivars and advance lines from Hungary and Pak. J. Agri. Sci., Vol. 53(1), 143-150; 2016 ISSN (Print) 0552-9034, ISSN (Online) 2076-0906 DOI: 10.21162/PAKJAS/16.2503 http://www.pakjas.com.pk


The explicit, above-the-water-line paradigm of information science is well known and widely discussed. Every disciplinary paradigm, however, contains elements that are less conscious and explicit in the thinking of its practitioners. The purpose of this article is to elucidate key elements of the below-the-water-line portion of the information science paradigm. Particular emphasis is given to information science's role as a meta-science—conducting research and developing theory around the documentary products of other disciplines and activities. The mental activities of the professional practice of the field are seen to center around representation and organization of information rather than knowing information. It is argued that such representation engages fundamentally different talents and skills from those required in other professions and intellectual disciplines. Methodological approaches and values of information science are also considered.

In metal-matrix composites (MMCs), the metal matrix is exposed to plastic deformation and damage accumulation in the region close to the reinforcements, following mechanical or thermal stress. In this connection, Al-4 wt pct Cu-based MMCs reinforced with 20 vol pct Al{sub 2}O{sub 3} fibers were characterized by internal friction (IF) measurements. The IF measurements as a function of the vibration amplitude present a solid friction peak connected with the loosening of metal-fiber interfaces, while plastic deformation was associated with a high amplitude IF background. On this basis, IF measurement allowed the authors to identify the distribution of internal stresses and damage accumulation at matrix-fiber interfaces or plastic flow in the matrix in different thermomechanical conditions. Furthermore, IF measurements allowed damage accumulation consequent to mechanical fatigue to be followed.


The achievable contrast level for space-based detection of exo-planets will be limited by the stability of the optics. As a consequence, active amplitude and phase compensation will be needed. In order to mitigate these wavefront instabilities, we suggested, as an alternative to classical adaptive optics, the use of a Michelson interferometer equipped with two deformable mirrors. Simulations showed that this set up is able to create a symmetric "dark hole" in an appropriate area of the image plane. However, increasing the bandwidth of the incident light critically alters this nulling performance. A quantitative analysis of this effect will first be presented. An alternative to circumvent this problem is to introduce a dispersive element in one of the legs of the interferometer so that the path length difference does not exhibit the one over wavelength dependence. In the case of the insertion of a gaseous cell, the OPD could then be controlled by pressure variations. The last section of this paper will present a simulation-oriented proof of concept relying on the dispersive properties of nitrogen.


"IoT" or "Internet of things" has been absolutely essential to our society and its infrastructures. Devices are linked to networks from anywhere in the world and will be mutually controlled while information is being exchanged. A microcontroller is one of the important elements of IoT. The microcontroller designers are strongly urged to achieve both high performance computation and low power consumption, which is a hybrid technology with powerfulness of computing and friendliness to the environment. This thesis focuses on the development of efficient microcontroller architecture for IoT. The basis for the argument is the key of a low power processor architecture is how effective handle on chip memories. Furthermore, collaboration of software and hardware on multicore architecture can provide dependable and secure networks. To test our hypothesis, we introduced RX processor core which is suitable for IoT. The RX processor Instruction set architecture (ISA) and its microarchitecture can achieve lower power consumption and boost performance. We presented eight-core communication SoC with PCI Express interface. The multicore SoC can realize a high performance, power-aware, highly dependable network. We also demonstrated a secure multimedia system by using heterogeneous multicore SoC and software virtualization.


The twenty-five-year-old war2 between the banking and insurance industries over bank insurance powers has recently culminated in courtroom confrontations in the Fifth and the District of Columbia Circuit Courts of Appeals. These judicial battles, initiated by the insurance industry to fend off incursions by banks into insurance markets, draw into question two statutory provisions granting limited insurance powers to national banks: the small-town bank insurance powers provision3 and the incidental banking powers provision.4 These provisions have been interpreted broadly by the Office of the Comptroller of the Currency (OCC)5 in favor of greater bank involvement in the sale of insurance. The insurance industry challenges the OCC's position as violating the expressed intent of Congress. The banking industry counters with the claim that the statutes are ambiguous and thus subject to reasonable interpretation by the OCC, pursuant to guidelines established by the Supreme Court of the United States. In deciding whether the banking or insurance position should prevail, courts have had to determine whether Congress's intent is clear from the language of the provisions or whether it is sufficiently ambiguous to warrant deference to the findings of the OCC.6 The D.C. Circuit and the Fifth Circuit

One sometimes hears the remark, &dquo;Teachers are born, not nzade.&dquo; A more sophisticated version might be that teachers are &dquo;nzade&dquo; mainly by their parents during childhood and adolescence. The writer of this article has long been interested in dynamic psychology ; that is, a study of the inner forces that make personality what it is. He shows, in the accompanying report, how many of these inner forces, established in early life, reveal themselves in teaching.


Purpose: Utilizing air thermal energy during over-heated time in the greenhouse is a necessary component to save greenhouse heating costs for nighttime. However, there is no practical way to implement the related principles. Methods: In this study, a heating and cooling system which utilizes the surplus air thermal energy in a greenhouse was developed. Available air thermal energy and heating load for this experimental glasshouse were estimated based on temperature conditions of the plant growth and weather data. Results: Estimated values were 400 MJ/day for maximum surplus air thermal energy and 340 MJ/day for maximum heating energy which were target values of the design as well. The system consists of a heat pump, fan-coil units and heat storage tanks which are divided into low and high temperature tanks. Moreover, a new control logic was developed for surplus air thermal energy utilization. Conclusions: This paper explains the details of conceptual design process of the system. Results of test operations showed that the developed system performed the recovery and supply of the thermal energy according to design purposes.


A displacement gradient method for 2D anisotropic elasticity problems is presented, which effectively minimizes the boundary layer effect through a two-step procedure. First, the boundary integral equations are solved for the unknown boundary displacements and tractions. Second, a direct integral equation for displacement gradients is developed in terms of boundary tractions. Three methods based on different evaluation procedures and locations for determining the displacement gradients are proposed. In the first method the displacement gradients are averaged at nodes common to adjacent elements. The second method stores the gradients element-wise. In the third method, the gradients are evaluated at the nodes of discontinuous elements. The three methods are applied to near-isotropic plates with circular and elliptic cutouts. It is concluded that all three methods can yield accurate stress distributions.


Chile has faced significant student unrest, and accompanying political instability. The causes of this activism were mainly increased tuition in higher education that were imposed without any improvement in academic standards.


Spatio-economic interactions among different categories of people and communities are crucial to the promotion of regional development in different parts of the world. Indeed, spatio-economic interactions involve both the movement of people from one place to another in order to undertake specific socio-economic activities that are capable of generating wealth for the people and the organizations that are involved in such movements and activities. The main objective of the study was to evaluate the commodity marketing and services systems' relationship with the spacio-economic interactions in Akure city and its' inner towns and villages in Nigeria. A simple questionnaire was adopted for the study. The study utilized both primary and secondary data. A structured questionnaire as well as interview was used to obtain the relevant data from a sample of twenty respondents. The discussion of Findings show that the Agricultural Product Marketing System in Akure and its' Inner Towns and Villages involve all categories of human settlement in the region in our consideration of agricultural product marketing activities and analysis. The study also revealed that the general orientation of the industrial product marketing sub-system in the region is almost the complete reversal of the agricultural marketing sub-system. Conclusively. There is need to intensity the caution that hunters and poachers should exercise restraint in killing animals in the vegetations secondly. The federal and state governments should not abandon the cocoa farmers to their fate. The cocoa farmers should not be left perpetually in the hands of the private cocoa merchants. Rather, the government ought to be involved indirectly in cocoa production through the provision of subsidy on inputs such as pesticides and storage devices. Keywords: Marketing, services systems relationship, Economic interaction, city, village.

Numerous studies have investigated spatial patterns of trend in streamflow. However, there is no consensus on the best methods to detect streamflow trends and the spatial extent or field significance of those trends. This paper looks at two of the contentious issues in trend analysis and assessment of field significance: serial correlation and cross-correlation. Both serial and crosscorrelation are known to reduce the accuracy of trend detection. The Trend-Free Pre-Whitening method was found to effectively remove the influence of serial correlation from a time series, enabling a more accurate assessment of site significance. An additional bootstrap test was developed to preserve the existing cross-correlation and to allow for a more reliable assessment of field significance. These methods and several others were applied to the annual mean, maximum and minimum streamflow data for 213 stations in the Canadian Reference Hydrometric Basin Network. These analyses revealed relatively consistent results for upward and downward trends for the three streamflow regimes. Mapping the results of these trend analyses revealed several interesting patterns, including three wide bands of trend that stretch across the country. A three band of downward trend stretches from Pacific to Atlantic at latitudes between approximately 50° and 58°; this band is particularly noticeable for the mean and maximum flows. A band of upward trend lies to the north of the downward band and stretches from northern B.C. and the Yukon through the Northwest Territories and into Nunavut; this band is noticeable for mean, maximum and minimum flows. A second band of upward trend lies to the south of the downward band, at latitudes between 44° and 50°; this band is noticeable for the same three flow variables.


Until quite recently, multicomponent recording has been a minor part of the seismic market, and systems have required expensive and time consuming adaptation to facilitate 4-C recording (three component velocity plus a pressure transducer). The cost and inconvenience of these adaptations has lead to a cost premium in 4-C. As the value of 4-C is becoming apparent, from numerous experimental surveys, it is now time to rethink some of the basic system design concepts to address the practicalities of efficient 4-C recording.


Today, we live in the Big Data age. Social networks, online shopping, mobile data are main sources generating huge text data by users. This "text data" will provide companies with useful insight on how customers view their brand and encourage them to make business strategies actively in order to maintain their trade. Hence, it is essential for the enterprises to analyse the sentiments of social media big data to make predictions. Because of the variety and existence of data, the study of sentiment on broad data has become difficult. However, it includes open-source Big Data platforms and machine learning techniques to process large text information in real-time. The advancement in fields including Big Data and Deep Learning technology has influenced and overcome the traditional restrictions of distributed computing. The primary aim is to perform sentiment analysis on the pipelined architecture of Apache Spark ML to speed upward the computations and improve machine efficiency in different environments. Therefore, the Hybrid CNN-SVM model is designed and developed. Here, CNN is pipeline with SVM for sentiment feature extraction and classification in ML to improve the accuracy. It is more flexible, fast and scalable. In addition, Naive Bayes, Support Vector Machines (SVM), Random Forest, Logistic Regression classifiers have been used to measure the efficiency of the proposed system on multi-node environment. The experimental results demonstrate that in terms of different evaluation metrics, the hybrid sentiment analysis model outperforms the conventional models. The proposed method makes it convenient for effective handling of big sentiment datasets. It would be more beneficial for corporations, government and individuals to improve their great value.


Antibiotics' effect on Mycoplasma pneumoniae (MP) infection still remains controversial. A 11 prospective study of 257 children with MP pneumonia during a recent epidemic (2015-2016) was 12 conducted. All MP pneumonia patients were treated with corticosteroids within 24-36 h after 13 admission. Initially, oral prednisolone (1 mg/kg) or intravenous methylprednisolone (IVMP) (1-2 14 mg/kg) was administered for mild pneumonia patients, and IVMP (5 -10 mg/kg/day) for severe 15 pneumonia patients. If patients showed persistent fever for 36-48 hours or disease progression, 16 additive IVMP (5 mg/kg or 10 mg/kg) was given. Eighty-five patients received only a 17 broad-spectrum antibiotic without macrolide. The mean age and the male:female ratio were 5.6 ± 18 3.1 years, respectively. Seventy-four percent of patients (190/257) showed immediate defervescence 19 within 24 h, and 95.7% (246/257) of patients showed defervescence within 72 h with improvements 20 in clinical symptoms. Eight patients who received additive IVMP also showed clinical 21 improvement within 48 h without adverse reactions. There were no clinical or laboratory 22 differences between patients treated with a macrolide (n = 172) and without (n = 85). Early 23 corticosteroid therapy might reduce disease morbidity and prevent disease progression in MP 24 pneumonia patients without side effects, and antibiotics may have limited effects on MP infection. 25

Variational quantum algorithms, which consist of optimal parameterized quantum circuits, are promising for demonstrating quantum advantages in the noisy intermediate-scale quantum (NISQ) era. Apart from classical computational resources, different kinds of quantum resources have their contributions in the process of computing, such as information scrambling and entanglement. Characterizing the relation between complexity of specific problems and quantum resources consumed by solving these problems is helpful for us to understand the structure of VQAs in the context of quantum information processing. In this work, we focus on the quantum approximate optimization algorithm (QAOA), which aims to solve combinatorial optimization problems. We study information scrambling and entanglement in QAOA circuits respectively, and discover that for a harder problem, more quantum resource is required for the QAOA circuit to obtain the solution. We note that in the future, our results can be used to benchmark complexity of quantum many-body problems by information scrambling or entanglement accumulation in the computing process.


Molecular dynamics (MD) simulation holds great promise as a source of otherwise elusive information concerning ionic conduction mechanisms occurring in the amorphous phases of polymer electrolytes. However, most polymer/salt complexes have a multiphase character at temperatures of interest. Insights into crystalline phases may thus prove meaningful in the subsequent design of strategies to decrease the degree of crystallinity in these systems. We report here the full details of a molecular dynamics model (''md'' model) for the crystalline phase of the widely used host‐polymer poly(ethylene oxide) (PEO). Force‐field and computational parameters are optimized to give realistic behavior for crystalline PEO. Analyses of the structure and dynamics obtained from the MD simulations performed at 300 K include mean‐square displacements, x‐ray powder diffractograms, distributions of bond and torsion angles, and radial distribution functions. These are compared with experimental data, the static x‐ray determined PEO...

In this paper, the work is to demonstrate the performance of single stage gas turbine which is able to operate with hot air as a working fluid at specific boundary conditions. These boundary conditions were chosen to be compatible with a Brayton cycle. The evaluation is dependent on the turbine efficiency and output power. Firstly, preliminary design work was completed in order to figure out the turbines shapes and find initial information about the impact of various factors on their efficiency values and output powers. Factors considered were: inlet pressure, inlet temperature, rotational speed and the mass flow rate. The performance was predicted at a constant pressure of 3 bars by varying inlet temperature (400K & 600 K) at different rotational speeds. Subsequently, three-dimensional computational fluid dynamics (CFD) modelling was completed for a gas turbine to study the effect of other factors and have accurate results. The simulation results showed that an improvement in total turbine efficiency from 45 to 66% for a fixed cycle boundary conditions.


Studies on carboxypeptidase characteristics of extracted solution produced by Actinomucor elegans 3.2778 in solid state fermentation of wheat bran were conducted, with the synthetic substrate N-terminal blocked peptide N-CBZ-Phe-Leu and Cd-ninhydrin method. The results showed that maximum carboxypeptidase activity was observed at pH 6.6 and 40℃ respectively. The enzyme was activated between pH 5.0 and 9.5 and was found to be unstable above 45℃. It was activated by Mg2+ at 0.99 mM and 9.10 mM, however, partially inhibited by Ca2+, Zn2+, Ba2+, Mn2+at two concentrations. The carboxypeptidase activity was completely inhibited by 1,10- phenanthroline, as well as PMSF and DFP.

With the rapid development of the industrial Internet, the security of industrial control network has become a vital topic. The network intrusion detection system (NIDS), as an important security device in contemporary networks, is of vital importance in detecting network traffic and ensuring network security. In this paper, a two-stage training Deep Neural Network (DNN) based on cross-entropy and focal loss, called CE-FL-NIDS, is proposed to handle with the problems caused to NIDS due to the uneven data distribution in the traffic dataset. The effectiveness of the proposed model is verified by performing 10-class classification on the UNSW-NB15 dataset. The experimental results show that: i) compared with the two-stage training DNN based on cross-entropy (CE-CE-NIDS), the proposed CE-FL-NIDS has increased the detection rate and F1-score by 8.76% and 6.37% respectively; ii) compared with the two-stage training DNN based on focal loss (FL-FL-NIDS), CE-FL-NIDS has increased the accuracy, DR and F1-score by 3.10%, 2.77%, 2.62% respectively. As compared to its counterparts, CE-FL-NIDS maintains the representation learning ability of DNN and improves the performance of the class imbalance NIDS.


In this study laccase mediated decolourization of Amido black, an azo dye was attempted. Laccase was extracted from the solid state fermentation of the white rot fungi Rigidoporus ulmarius on rice bran (50%). The enzyme activity was assayed using guaiacol as substrate and was found to be 0.0145 U/ml. The crude enzyme extract was employed for decolourization experiments. Optimization of the effect of contributing variables; pH, temperature, dye concentration and enzyme volume on decolourization was primarily analysed using OFAT (One Factor At a Time) approach. The optimum operating conditions for maximum decolourization were further statistically optimized by applying the Response surface methodology using Box-Behnken approach. A four factor three level Box-Behnken design generating 29 experimental runs was performed. A quadratic model was fitted and was analyzed using ANOVA at the 95% confidence interval. The determination coefficient R 2 was found to be 0.9616 indicating the significant fit of the model. The optimum operating conditions predicted by the model was found to be at constant incubation time of 24hrs, pH of 4; temperature of 30°C; dye concentration of 150mg/l and enzyme volume of 1.25ml producing 83.39% decolourization which was in good agreement with that of the predicted value, 83.24%.

Abstract Background The ABR is useful for estimation of hearing thresholds and is considered an objective test since cooperation of the infant is not required. However, wave 5 identification and threshold determination are often based on the audiologist's subjective judgement. The aim of the present study is to describe the developmental changes in ABR wave 5 latency to different stimuli and intensities in infants of different ages. Materials and methods Data from the files of 294 normal hearing infants were used in a retrospective analysis. The latency of wave 5 brainstem component of the ABR to click and tonal stimuli at different intensities down to threshold were measured. Results The wave 5 latency to click was shorter than for tonal stimuli. Furthermore, the rate at which latency of wave 5 decreased as a function of stimulus intensity was more pronounced over the higher intensities. The shortening of wave 5 latency was also more rapid over the first few months in response to the higher frequencies. Discussion and conclusions Latency values obtained were similar to those described in the literature; wave 5 latency for different frequencies followed the tono-topic organization of the cochlea and the decrease in latency followed neural maturation. Further investigation is needed to determine if the latency values at threshold in infants with hearing loss are similar.


Cooperation between companies and universities facilitates the production of knowledge and its transformation into new productive technologies, contributing to business competitiveness and regional areas in a globalized world. Given the importance of the subject, this article was developed with the aim of identifying the practical relations between government, universities and companies from Ceará in relation to technological innovation. The research methodology is qualitative in nature, with character exploratory and qualitative. Data were collected through desk research and interviews with stakeholders of innovation state, selected by convenience and accessibility. The information was processed by content analysis, revealing that there are differences between universities and companies as to the reasons for the production of knowledge, time of execution of projects, knowledge of the purpose of research, but the potential gains associated with cooperation for the parties involved and State to create real opportunities for the development of the relationship between these agents. There is, however, for this, the need for the Government to exercise a more effective role in the articulation of these actors, clearly defi ne the strategic sectors for innovation, promote the Innovation Law in Ceará and take other specifi c measures identifi ed for promoting innovation.


Semiconductor moir\'e superlattices have been shown to host a wide array of interaction-driven ground states. However, twisted homobilayers have been difficult to study in the limit of large moir\'e wavelength, where interactions are most dominant, and despite numerous predictions of nontrivial topology in these homobilayers, experimental evidence has remained elusive. Here, we conduct local electronic compressibility measurements of twisted bilayer WSe$_2$ at small twist angles. We demonstrate multiple topological bands which host a series of Chern insulators at zero magnetic field near a 'magic angle' around $1.23^\circ$. Using a locally applied electric field, we induce a topological quantum phase transition at one hole per moir\'e unit cell. Furthermore, by measuring at a variety of local twist angles, we characterize how the interacting ground states of the underlying honeycomb superlattice depend on the size of the moir\'e unit cell. Our work establishes the topological phase diagram of a generalized Kane-Mele-Hubbard model in tWSe$_2$, demonstrating a tunable platform for strongly correlated topological phases.


We demonstrate efficient light extraction from the active region of bottom-emitting organic light emitting devices (OLEDs) using a high refractive index, nondiffractive hemispherical microlens array located between the transparent anode and embedded in the low refractive index glass substrate (n = 1.5). The subelectrode microlens array (SEMLA) results in a maximum external quantum efficiency of 70 ± 4% for green phosphorescent OLEDs (PHOLEDs). Furthermore, the wavelength- and viewing-angle-independent light extraction structure results in white PHOLED external efficiencies of 50 ± 3%. The SEMLA light extraction structure is nonintrusive; that is, it lies completely outside of the OLED structure. Since this design has no effect on the image resolution, it is compatible with applications for both displays and white light illumination, with no dependence on molecular transition dipole orientation and the active organic layers (and hence diode electrical characteristics) used in the PHOLED. Finally, due to th...


Buildings are responsible for a significant portion of energy consumption in the US, accounting for more than 40% of US primary energy consumption. Heating, ventilation and air-conditioning (HVAC) accounts for nearly 50% of that use. Conditioning buildings is important since people spend 87% of their time in the place they live (residential) and the place they work (commercial). Despite this massive expense, many users are dissatisfied with the thermal conditions in buildings. Savings made in HVAC systems, therefore, have a major impact on energy consumption and cost, together with the reduction of greenhouse emissions for the nation. Equally critical is to provide thermal quality of service to their users, so people are comfortable in the place they reside and work.In this paper, we explore the tradeoff between commercial building HVAC energy consumption and the quality of thermal conditioning provided to users. We argue that optimal HVAC control cannot be achieved due to lack of critical information, namely where the users are inside the building, what do they want with respect to thermal comfort and how each zone responds to thermal changes. In this work, we present OFFICE, a model predictive control (MPC) framework for smart building HVAC control. The framework has several components that help to address the current HVAC control systems shortcomings, including (a) occupancy sensing in real-time, (b) occupancy prediction models based on historical occupancy data, (c) human-in-the-loop comfort feedback, (d) data-driven thermodynamic building models, and (e) weather forecasting data. All these components provide the necessary input to our model predictive control optimization framework that minimizes monetary costs in energy use while maintaining quality comfort bounds for the building's users based on real-time user's feedback. We developed a large system that involves all the above components, replacing the Building Management System control algorithms, taking over full control of the HVAC system. We tested OFFICE in a real LEED Gold certified university building with over 20 workers performing their daily tasks for 4 weeks, and we showed that we could obtain monetary costs savings of more than 10% while at the same time reducing the users' dissatisfaction levels with thermal comfort from 25% to 0% dissatisfaction, significantly improving the quality of thermal service provided to the building's users.


In this paper, we present a behavioral SIMULINK model for the simulation of operational amplifiers (op-amp). The model includes most of the nonlinearities which affect the performance of these circuits, such parameters (noise, finite gain, finite bandwidth, and slew-rate).With the proposed models it is possible to accurately predict with fast simulations the linearity of sample and hold (Stll) circuit and Multiply digital-to-analog (MDAC) circuit that constructed the pipelined ADC.


To the Editor: Pathogenic recombination-activating gene 1 (RAG1) variants cause a phenotypic spectrum ranging from severe combined immunodeficiency (SCID) to combined immunodeficiency with granulomas and autoimmunity (CID-G/A), depending on residual recombinase activity.1–4 Our patient, a 12-year-old African American female with hypogammaglobulinemia and T-, B-cell lymphopenia, was diagnosed with CID at 5 years of age, with a history of recurrent herpes simplex virus (HSV) gingivostomatitis, bacterial pneumonia, and cutaneous abscess. She tolerated two doses of live measles– mumps–rubella (MMR) vaccine. She was referred to our facility for steroid-refractory sterile non-caseating cutaneous granulomas (Figure S1) affecting posterior thigh and midface, appearing at 9 years and with progressive lymphopenia (Figure 1A) concerning for a CID. Next-generation sequencing identified compound heterozygous pathogenic RAG1 variants, c.1187G>A, p.Arg396His and c.1566G>T, p.Trp522Cys (NM_000448.2). Residual recombinase activity is estimated at 40%–50% for RAG1-Trp522Cys and less than 5%–30% for RAG1-Arg396His.2,5,6 Immunofluorescent staining of granulomas identified rubella virus antigen in neutrophils in the necrotic region of deep dermis and a few CD206 M2 macrophages7 (Figure S2). Reverse transcriptionpolymerase chain reaction (RT-PCR) and sequencing detected vaccinederived rubella virus (VDRV) genomic RNA in nasopharyngeal secretions, while urine and peripheral blood (PB) were negative. PB markers of persistent rubella infection were detected: rubella-specific IgM antibody and elevated titers of rubella-neutralizing antibody (NT50 = 400). 7,8 T-cell phenotyping demonstrated reduced frequency of naïve T cells with relative expansion of CD45RO memory T cells (Figure 1B,C), and evidence of cellular exhaustion (PD1, data not shown). T-cell proliferation to Candida and tetanus toxoid was normal. Class-switched memory B cells were absent, while CD19+CD21dim B cells (anergic autoreactive subset with potential for altered homing, autoimmunity) were expanded. Autoantibodies to interleukin (IL)12, IFN-α, or IFN-ω previously reported in CID-G/A were absent.1,2 CD3Vα7.2CD161 mucosal-associated invariant T cells (MAITs) were undetectable (Figure 2A). Degree of loss of MAIT, a sensitive biomarker of TCR-Vα rearrangement defects, has been correlated with phenotypic severity in CID-G/A.1 CD4CD45RO memory T cells expressing CD162 and CCR9 (facilitating homing to skin, gastrointestinal mucosa), were significantly reduced (Figure 2B). TCR-Vβ spectratyping confirmed expansion of an oligoclonal T-cell repertoire. Frequency of CD127 innate lymphoid cells (ILCs) was increased, with relative expansion of ILC2 and ILC3 subsets (Figure 2C). The patient underwent a 10/10 matched-unrelated bone marrow hematopoietic cell transplantation (HCT) following busulfan/fludarabine/alemtuzumab conditioning with tacrolimus/methotrexate for graft-versus-host disease (GvHD) prophylaxis.9 Early post HCT, the granulomas regressed, though infections included HSV gingivostomatitis, BK hemorrhagic cystitis, and adenoviremia (responsive to pharmacotherapy). She achieved full (99%) donor chimerism (FDC) in the myeloid lineage by day (D) +30 and in CD3 T cells by D+59. At D+95, she showed persistent T-cell lymphopenia with absent naïve CD4 T cells (Figure 1A). There was evidence of B-cell recovery (CD19 B-cell lymphocytosis, presence of class-switched memory B cells), likely facilitated by the few memory and/or follicular T helper cells. On D+170, she developed warm autoimmune hemolytic anemia (AIHA) with reticulocytopenia and parvovirus reactivation. Bone marrow showed erythroid arrest. Following transient response to intravenous immunoglobulin and corticosteroids, she had multiple relapses of AIHA with emergence of cold agglutinin and Cartwright red-cell-antigen antibodies. Response to daratumumab and eculizumab lasted 4 weeks, with no response to subsequent therapies (rituximab, cyclosporine, abatacept). She had no thymic reconstitution with absent naïve T cells. On D+272, she remained at FDC in CD19 and CD56 fractions, ruling out expansion of autoreactive recipient clones. Thirteen months post HCT, she underwent a second HCT using CD34 selected PB stem cells (same donor) following therapeutic plasma exchange (TPE). She received fludarabine/alemtuzumab and total lymphocyte irradiation (200 cGy) with no GvHD prophylaxis. Infections at the time of second HCT included adenovirus (on cidofovir) and parvovirus DNAemia. Despite FDC status onD+30post secondHCT, she remained lymphopenicwith no naïve T cells. Themajority of lymphocytes (85%) were CD8 T cells, with no CD19 B cells (Figure 1A). Following a transient response, 2 months later she presented with hemoglobin 2.6 gm/dl secondary to AIHA. Despite TPE and bortezomib, she succumbed at D+50 post secondHCT to right ventricular failure.


A Frequency-to-Code Converter (FCC) is presented in which a counter clock automatically slows down its pace as the interval between the last pulse and the next one exceeds some prededetermined value. This technique ("frequency-grading") allows building a simple broad-band (10-65 000-Hz) FCC with a 1-percent accuracy for frequencies higher than 50 Hz.


Abstract A fundamental statistical test of serial independence developed by Ashley and Patterson (1986) to examine a possible form of serial dependence in daily stock returns is shown to be improperly constructed. As a consequence, the significance probabilities that they obtain are overstated. This paper presents a corrected version of their test. The test statistic obtained after correction is shown to possess the same limiting distribution as the Kolmogorov-Smirnov test statistic. Applying the corrected test procedure to data identical to that used by Ashley and Patterson, we find that their original null hypothesis can no longer be rejected at conventional significance levels.


We attempt to integrate previous partial explanations for the greater diversity and abundance of lizard species in arid Australia with new ideas concerning spinifex grasslands, the habitat with the most startling lizard diversity, in order to present a more comprehensive and testable theory than has hitherto been provided. Our synthesis focuses on the factors allowing diversification in local assemblages, not on between-habitat diversity. Our argument has four major components. 1. Spinifex grasses grow on unusually infertile soils, and spinifex is nutritionally very poor. Thus, herbivorous animals are relatively uncommon, whereas termites are exceedingly common and diverse. Acacia shrubs grow on firm soils that are only slightly more fertile than sands; and termites are probably even more abundant here than in the grasslands. Chenopod shrubs and tussock grasses, which grow on relatively fertile soils, probably have considerably fewer termites. 2. The diversity of lizards increases from fertile vegetational formations to infertile spinifex grasslands and acacia shrublands. We suggest that termites, being individually small but abundant, provide a food resource particularly suitable for lizards. Consequently, lizards have been able to diversify, especially where sandy soils allow subterranean activity. 3. Four contributory factors appear to have enhanced the abundance and diversity of Australian lizard species. Vegetational production in arid Australia is uncertain because the variability in rainfall is high and droughts may be lengthy; hence, ectothermic lizards are favored over birds and mammals. Nevertheless, aridity is mild and vegetational cover is usually high, thereby providing abundant food for termites. Because many termites forage nocturnally, abundant resources are available for exploitation by nocturnal lizards. Finally, arboreal lizards are prominent because climatic peculiarities allow trees to grow sparsely throughout arid Australia; the added structural complexity allows further diversification of termites and lizards. 4. Our interpretation is broadly consistent with available literature on lizard and termite faunas in arid Australia, North American deserts, and the Kalahari Desert, although important gaps remain. Our hypothesis consists of a web of forces rooted in the edaphic and climatic characteristics of arid Australia. It suggests that lizards are better suited than other vertebrates to infertile and arid environments because of their morphological and physiological characteristics; this phenomenon reaches its climax in Australia.


In this paper developing turbulent forced convection flow of a water–Al2 O3 nanofluid in a square channel submitted to a constant and uniform heat flux at the wall is numerically investigated. A single model and two-phase models (discrete particles model and mixture model) are employed with constant temperature properties. The investigation is accomplished for a size particles equal to 38 nm. The CFD commercial code Fluent is employed to solve the problem by means of finite volume method. Convective heat transfer coefficient for nanofluids is greater than that of the base liquid. Heat transfer enhancement is increasing with the particle volume concentration but it is accompanied by increasing wall shear stress values. The effect of Reynolds number is great for higher concentrations. The results obtained by tree different models are presented in terms of temperatures and velocity distributions, relative increasing of heat transfer coefficient, hr , and Nusselt number profile.Copyright © 2008 by ASME


Submitted for the MAR16 Meeting of The American Physical Society Kondo and Majorana doublet interactions in quantum dots YOUNGHYUN KIM, UC Santa Barbara, DONG E. LIU, Microsoft Research Station Q, ERIKAS GAIDAMAUSKAS, JENS PAASKE, KARSTEN FLENSBERG, Niels Bohr Institute, University of Copenhagen, ROMAN LUTCHYN, Microsoft Research Station Q — We study the properties of a quantum dot coupled to a normal lead and a time-reversal topological superconductor with Majorana Kramers pair at the end. We explore the phase diagram of the system as a function of Kondo and Majorana-induced coupling strengths using perturbative renormalization group study and slave-boson mean-field theory. We find that, in the presence of coupling between a quantum dot and a Majorana doublet, the system flows to a new fixed point controlled by the Majorana doublet, rather than the Kondo coupling, which is characterized by correlations between a localized spin and the fermion parity of each spin sector of the topological superconductor. We find that this fixed point is stable with respect to Gaussian fluctuations. We also investigate the effect of spin-spin interaction between a quantum dot and Majorana doublet and compare the result with a case where a normal lead is directly coupled to Majorana doublet.

Two stages of photoluminescence aging were observed which are connected with desorption and oxidation processes.


The higher education sector in Australia is under increasing pressure to prove quality and efficacy of education provision, including graduate outcomes. One of the central tasks of higher education has become to prepare nascent professionals as far as possible for initial employment and future working lives beyond this (Boden & Nedeva, 2010). Tertiary educators in the creative arts face significant and distinctive challenges in demonstrating graduate employability, and creative graduates consistently have the poorest outcomes of any subject grouping. In part, this is because the national graduate destinations survey (Graduate Careers Council of Australia, 2012) does not cater to the distinctive 'portfolio' nature of creative careers, or take account of the fact that creative careers can take concerted effort over several years to establish (e.g., McCowan & Wyganowska, 2010).

However, it is worth asking whether we as tertiary arts educators are doing enough to prepare creative arts students for the world of work, particularly given that the majority of them will be self-employed to some degree (Bureau of Labour Statistics, 2011, Throsby & Zednik, 2010), and will be challenged to build their own careers without recourse to the support of HR departments or intra-firm promotion schemes. It has been demonstrated empirically that career management and creative enterprise skills are among the most important graduate capabilities in determining early creative career success (Bridgstock, 2011), although these skills do not appear in the Learning and Teaching Academic Standards for the Creative and Performing Arts (2010).

This paper explores the nature and development of enterprise capabilities for creative arts students (as distinct from students of the business school), examines best practice in the field internationally, and proposes a theoretically-driven creative arts-specific enterprise curriculum model which commences in first year, for demonstrable impact on student enterprise behaviours (such as grant seeking, professional networking and intention to start an enterprise) and employability.


FIELD: physics. SUBSTANCE: lens having a field angle larger than 180 degrees and includes a front group, a reflection surface and a back group. The front group includes three negative lenses, the reflection surface changes the direction of the optical axis by an angle of 90 degrees and the back group includes four positive lenses. The front principle point is located between the second lens and the third lens in the front group. The focal length f of the lens and the distance d between the intersection of the reflection surface and the optical axis and the front principle point satisfy the condition 7.0<d/f<9.0. The imaging device includes two optical imaging systems, comprising a wide-angle lens and an imaging sensor and linked such that the lenses are located opposite each other, and images are synthesised to obtain an image in a solid angle of 4π radians. The distance d1 and d2 between the intersection of the reflection surface and the optical axis and the front principal point in the wide-angle lenses of the imaging system and the focal length f of the wide-angle lens satisfy the condition 16≤(d1+d2)/f<21. EFFECT: reduced image disparity and high image quality. 6 cl, 6 dwg


We fabricated a quantum dot infrared photodetector (QDIP) with 5-stacked self-organized InAs quantum dots embedded in a high electron mobility transistor-like modulation doped structure and utilize lateral electron transport. A peak response of the QDIP appeared at λ=10.5 µm at T=80 K. We also found that the device exhibits bias-dependent responsivity.


Under the disturbed and undisturbed conditions,the effects of six tobacco varieties and five different temperatures on perching and oviposition of Bemisia tabaci B-biotype were respectively studied.The results showed that there were significant effects of varieties and temperatures on perching and oviposition selectivity of B.tabaci B-biotype.Under the same temperature,the numbers of adults and eggs were the most on Honghuadajinyuan and the least on Yunyan 87 and Yunyan 85;on the same variety,the numbers of adults and eggs were the most at 26 ℃ and the least at 18 ℃ and 34 ℃.


Sustainability models should consider aspects of the economy-environment-population nexus, be dynamic, and acknowledge the disparity among actors/countries. Lastly, sustainability models should not be programmed either to reject sustainability (e.g., an essential, nonrenewable input) or to affirm it (e.g., costless, endogenous technical change). We develop a simulation model to assess sustainable development on three levels: economic (by determining production, consumption, investment, direct foreign investment, technology transfer, and international trade), social (by calculating population change, migration flows, and welfare), and environmental (by calculating the difference between environmental pollution and upgrading expenditures). The model follows "representative" countries that differ in their initial endowments (i.e., natural resource endowment, physical and human capital, technology, and population), and thus in their development levels and prospects. In addition, we model free substitution in production, flexible economic structures, the ability to upgrade input factors via investment, and optimizing agents who possess a high degree of mobility and information, and who interact through and in response to market equlibiria.


Objective. Coeliac disease (CD) susceptibility has been shown to be associated with the HLA alleles DQA1*0501 and DQB1*0201. This HLA-associated risk has been estimated to account for 29–40% of the genetic component of CD. Conflicting data have been published on the gene dose effect of these HLA alleles on the risk and severity of CD. In this study the aim was to investigate the association between the number of HLA risk alleles and the severity of CD. Material and methods. Fifty-four Finnish CD families, including 144 CD patients mainly diagnosed in adulthood (94.4%), were enrolled in the study. The association between the number of DQA1*0501 and DQB1*0201 alleles and villous atrophy, symptoms and laboratory parameters at the time of diagnosis, and the association with villous atrophy after one year of treatment on a gluten-free diet were studied. Results. The homozygosity for the DQB1*0201 allele was associated with a more severe form of CD assessed by more severe villous atrophy (p=0.011), younger age (p=0.036), more severe diarrhoea (p=0.048) and a lower level of blood haemoglobin at the time of diagnosis (p=0.010). Furthermore, the homozygosity for the DQB1*0201 allele was associated with a slower recovery of villous atrophy after a gluten-free diet (p=0.041). In contrast, the DQA1*0501 allele did not have a significant association with the severity of CD. Conclusions. Our results demonstrate a gene dose effect of the DQB1*0201 allele on the clinical heterogeneity of CD and on the rate of recovery from villous atrophy in patients on a gluten-free diet.


This paper presents a novel rotor structure of interior permanent magnet synchronous motor (IPMSM) using rare earth and ferrite magnets for some concerns about future supplies of materials. In this IPMSM, the total volume of Nd-Fe-B magnets can be reduced by 58 % compared with a basic IPMSM model. We analyzed motor characteristics such as the torque, efficiency, stress in the rotor, and demagnetization of permanent magnets by the three-dimensional finite element method (3D-FEM). According to simulation results, the torque and efficiency in the proposed IPMSM are better than those of the basic IPMSM model.


Sleep disturbances caused by noise exposure are the most relevant outcome measured in disability adjusted life years (DALYs). In analogy to the combined effects of noise from multiple sources on annoyance, these are also of interest for sleep disorders. The study "Overall Noise Assessment" Innsbruck examined data from 1031 personal interviews. Aircraft, rail and road noise were correlated. To choose participants combined exposures were clustered into small, medium and severely affected living situations. The effect of demographic features, noise sensitivity, access to a silent façade and other factors on self-reported sleep disturbances was investigated applying bivariate analyses. Exposure-response curves and their 95% confidence intervals with cut-off values of 72% for "highly disturbed sleep" were generated and the results were discussed in comparison to recently published curves. Using source-specific exposure-response relationships, an overall model for evaluating sleep disorders was developed based on the "annoyance equivalents model". The "total sleep disturbance response" shows an accumulative outcome for each source measured. A protective effect of road traffic noise as background noise for air and railroad sources could not be proven. Both the "Total Sleep Disruption Assessment Model" and the "Dominant Source Model" have a Spearman-Rho of 0.3 and are therefore suitable for use in noise assessment.


Thaumetopoea hellenicaand Thaumetopoea mediterraneawere recently described from Central Greece andPantelleria Island (Italy), respectively. In this paper, we reported some information on their morphology, biological cycleand ecology. T. hellenicaand T. mediterraneaare closely related to T. pityocampa differing mainly ingenetic characters.Morphologically, the three species resemble each other, and can be mainly differentiated by observing wing patterns, can-thus, and the male and female genitalia. Some data on egg batches, mature larvae, pupae, flight period, host plants andcolonized environments were reported.


Kropotkin's extensive writings on criminological issues have been almost totally neglected. Through critical historical and macro-structural analyses Kropotkin assessed institutional arrangements disclosing how they were or were not meeting human needs. Our exploration focuses on Kropotkin's theoretical contributions, his feelings-based criminology and his extremely insightful dualistic conceptualization of "human nature". His contributions to penology, and his assessment of social arrangements which would meet the complex and ever-changing needs of humankind are briefly examined. Kropotkin's analytic framework provides an insightful and provocative base from which to synthesize criminological thought and research and from which to take action to alter social arrangements which do not meet human needs. Although Peter Kropotkin wrote extensively on criminological issues, criminologists have neither acknowledged his insights nor adopted his analytical framework. Perhaps this has occurred because anarchist perspectives have been perceived as beyond the scope of acceptable criminological thought; or perhaps because feelings, which some feel have no place in scientific discourse, hold a central place in Kropotkin's analyses. Regardless of the reason for neglect, Kropotkin's ethical humanism and analyses of


Cloud based end to end digital project management platform with digital control tower, as fundamental technologies of the fourth industrial revolution, have enormous potential to improve real time visibility, productivity, collaboration, data sharing, efficiency, predictability, decision power and sustainability in the construction industry.
 Throughout the lifecycle of capital / mega projects, the engineering, construction, operations, and maintenance stakeholders face numerous issues, including the lack of trust and visibility, inefficiencies, and the fragmentation of the information value chain into fragile data silos. Digital control tower aimed to narrow down the time, budget and quality & safety challenges of a capital project by having overall / end to end control of project from initiation phase to handover and operations phase of the project.

 Digital control tower provides systematic, 360-degree view of project details along with real-time analytics spanning from design engineering, pre-construction planning, onsite execution, action tracker, construction services, equipment's, quality, budget and safety (leading and lagging indicators).
 Stakeholders involved throughout the project lifecycle (i.e.: owner, engineering team, pre-construction and planning team, construction management and site team), enables instantaneous connectivity from the top floor to the shop floor for seamless communication by reducing waste time.
 Digital control tower also enables bird's eye view for real time project performance monitoring and progress, it also enables week wise look ahead task for better monitoring and control, also narrows down the issues or concerns to an activity, area or person. The control tower can create the customizable necessary discipline/function dashboards available to all relevant roles and stakeholders without limitation.

 Digital Control Tower leverages Artificial intelligence, Machine learning and Blockchain technologies to seamlessly capture, maintain and process fragmented data set into intelligent predictive analytics which helps the project stakeholders to take right decision on right time, so as to avoid any kind of delays in project.

 Digital Control Tower is not a standard dashboard, it's an integrated digital ecosystem where stakeholders can drive projects with real time data for decision making.


The RDF-based dynamic semantic search algorithm is discussed, and on the basis a cluster-based RDF dynamic semantic search algorithm is proposed. Comparing the algorithm with original algorithm, the main virtue of the algorithm is, when the query condition matches with target resources, to restrict the search range to the attributive semantic clusters of super-peer and the presidial autonomic peer clusters of super-peer, i.e., it reduces the search range from all peers in semantic P2P network to those peers of the attributive semantic clusters of super-peer and the presidial autonomic peer clusters of super-peer, avoids requested flooding effectively, greatly shortens search time and raises search efficiency.


This study examined the dynamics and profile distribution of soil electrical conductivity(EC) in an aquic brown soil at the Shenyang Experimental Station of Ecology,Chinese Academy of Sciences under four land use patterns.They are paddy field(PF),maize field(MF),fallow field(FF),and woodland(WL) respectively,setting experiment over 14 years.In each pattern at the depth of 0150cm,soil samples were collected from ten layers.The results showed that soil EC was significantly different from each other under different land uses and at various depths.In the layer of 0-5cm,soil EC was significantly lower in MF than in the other three land uses.The average value of soil EC at the depth of 0-150cm was in the order of WLFFMFPF.The comparatively higher soil EC at the depth of 0-30 cm in PF was probably due to the eluviation of bases and the rebasification in soil during the process of rice-planting,while the higher soil EC at the deeper layers in WL was the consequence of tree root distribution.There were different relationships between soil EC and soil organic C,total and available N,P and S,pH,exchangeable Ca,Mg,K and Na,and DTPA extractable Fe,Mn,Cu and Zn under different land uses,reflecting the influences of the biogeochemical cycling of under different land uses on soil EC dynamics.It is suggested that soil EC,as an easy measured soil chemical parameter,is effective to indicate the influences of land use on soil physiochemical property variations.


ABSTRACT: This study measured Fc gamma receptor (FcR) expression on polymorphonuclear leukocytes (PMN) and monocytes from extremely premature infants. Flow cytometry was used to quantitate FcRIII [cluster of differention (CD) 16], FcRII (CD32), FcRI (CD64), CD14, and CD67 proteins on the PMN surface. Sixty-four premature infants with a mean gestational age ± SD of 26 ± 2 wk (birth weight = 847 ± 217 g), 12 infants born at term (gestational age = 38 ± 1 wk), and 37 adults were studied. Premature infants' PMN expressed less FcRIII, measured as mean log channel fluorescence (MCF), than did term infants or adults (MCF = 4.7 ± 1.4, 6.1 ± 1.0, and 8.8 ± 1.8, respectively, p < 0.050). Premature infants also had a lower proportion of FcRIII-positive PMN than term infants or adults (mean ± SEM = 0.83 ± 0.02 versus 0.92 ± 0.04 and 0.96 ± 0.01, respectively, p < 0.050). FcRIII expression on PMN was positively associated with cell isolation procedures (p = 0.004), birth weight (p = 0.004), and postnatal age (p = 0.032). Premature infants also had lower PMN expression of FcRII when compared with adults and term infants (MCF = 2.4 ± 0.6 versus 3.0 ± 0.7 and 3.1 ± 0.3, p < 0.050). Both premature and term infants had fewer FcRII positive PMN than did adults (mean ± SEM = 0.90 ± 0.09 and 0.89 ± 0.07 versus 0.99 ± 0.00, p < 0.050). Premature infants' monocytes also expressed significantly less FcRIII (MCF = 2.4 ± 0.6 versus 3.4 ± 0.9, p = 0.047) and FcRII (2.1 ± 0.5 versus 2.9 ± 0.6, p = 0.01) compared with adults. We conclude that extremely premature infants have decreased expression of FcRIII and FcRII on both their PMN and monocytes when compared with adults. The decrease in PMN FcRIII expression appears related to birth weight and chronologic age.


Limanda limanda is one of the important fish of U.K. and European market. It is a bottom feeder and usually caught together with plaice and flounders. In the present study, fecundity of Limanda limanda was determined. A regression line has been drawn between fecundity and fish length. A cur- vilinear relationship was obtained and it was found to be 0.0046 L 5.27. A logarithmic relationship between fecundity and weight of the fish is also plotted.


Objective To detect the expression of bcl-2 and bax gene in breast carcinoma and its pathological charac- teristics. Methods Immunohistochemical technique was used to detect the expression of bcl--2 and bax gene in 54 cases of breast carcinoma, 31 cases of para--carcinoma tissues and 8 cases of benign breast diseases. Results The positive rate of bcl-2 in breast carcinoma (BC) was 57. 4 %, and the positive rate of bax in breast carcinoma was 79. 6%. The positive rates of bcl-2 in BC grad Ⅰ,BC grade Ⅱand BC grade Ⅲ were 72. 2, 61. 5% and 30% respectively. There was no sig- nificant difference of bcl--2 expression in each grade of breast carcinoma. The positive rate of bax in BC grade Ⅰ,BC grade Ⅱ and BC grade Ⅲ were 100%, 88. 5%, 20% respectively. There were significant differences of bax expression in each grade of breast carcinoma. And there were significant differences of bcl-2 and bax positive rate among benign breast diseases, para-carcinoma tissues, in situ breast carcinoma and invasive breast carcinoma. Conclusion bcl-2 and bax gene plays an important role in breast carcinoma growth and development, and relates to regulation of cell apoptosis in breast carcinoma.


Up to now, 39 species of the family Anthribidae have been recorded from Korea. As a result of this study, we add two genus and four species of the family Anthribidae to the Korean fauna with brief descriptions and illustrations of diagnostic characters. The newly recorded genus Citacalus in the subfamily Choraginae, is very similar to the genus Choragus. Citacalus pygidialis Johraku has an unique character, pygidium strongly convex longitudinally sharply carinate on the apical half in male; in female, pygidium triangularly projecting laterally near the apex. The newly recorded species Euparius modicus yaeyamanus Morimoto in the genus Euparius of the subfamily Anthribinae, can be distinguished from the other two recorded species by the elytra with almost unicolor pubescence color except a pair of black spots behind middle. The newly recorded genus Unciferina is close to Uncifer Jordan, but easily distinguished from the latter by sharply angulate rostrum to head, transversely carinate base of rostrum on the underside, and the acute hind angles of pronotum. The two new species in the genus Unciferina are easily distinguished from the congeneric species with pubescence patches on pronotum and elytra, shape of eye, the ratio of the antennal segments and the shape of the hind angles of pronotum.


Sex determination from skeletons is an important research subject in forensic medicine. This study aimed to evaluate the sexual dimorphism in the Egyptian skulls based on foramen magnum and some cranial measurements. Methodology: The present study was performed on 100 adult Egyptian patients of both sexes. MultiSlice Computerized Tomography (MSCT) scan were obtained and reconstruction of 3D models for the cranium was performed. Various parameters related to the foramen magnum, the right condyle and the left condyle were measured on virtual skulls of adult patients. Results: The mean length, width and area of foramen magnum were significantly higher in males(35.3 ± 1.9mm, 30.0 ± 1.9mm and 833.50±72.52mmrespectively) than in females(32.8 ± 2.5mm, 27.1 ± 2.4 mm and 699.90±92.09mmrespectively). The mean lengths of the maximum bicondylar distance, minimum intercondylar distance and maximum medial intercondylar distance were significantly longer in males(48.8 ± 2.3 , 17.2 ± 1.7 and 25.1 ± 2.4mm respectively) than in females (46.1 ± 2.2, 16.2 ± 1.8 and 22.7 ± 1.7mm respectively ). A significant difference between males and females was elicited regarding the length (24.8± 1.7 and22.7±2.2mm respectively) and the width (14.4±1.3 and 13.5±1.3mm respectively) of the right condyle. The equation which determines sex with high accuracy was the one made from the length of the foramen magnum, length of the right condyle and length of the left condyle, the accuracy reached 87%. Conclusion: It can be concluded that measurements of the foramen magnum and the condyles obtained using 3D CT and the equations acquired from them are reliable tools in sex determination.

Introduction: In an Orthodontic and a Periodontal practice the most frequently missing teeth were the third molars followed by the mandibular M1 and the maxillary PM1.
Objective: To record the incidence of absent teeth/missing teeth amongst patients attending differing dental practices.
Materials and methods: Data recording age, gender and missing teeth (jaw and side) were drawn from the records of the initial consultations of patients attending five practice types: orthodontic (n 194), periodontal (n 202), prosthodontic (n 137), general dental practice (n 115) and Oral Hygiene Clinic (n 156). Excluded were patients under age 20 and those attending for oral medicine consultation (no dental charting).
Results: Mean ages (group, sd) ranged from 34.7y (orthodontic 9.8y) to 50y (prosthodontic 12.2y). Jaw side had no effect on missing teeth in any group (Z test). M3 were the most frequently missing teeth, followed by maxillary PM1, mandibular 1, PM1 and PM2. Age in decades effected the most dominant influence, followed by Practice Group, with gender having a weak effect on M3 data (linear logic analysis).
Conclusions: Molars and premolars were the most frequently absent teeth. Different dental patient populations experience differing patterns of tooth loss, although the reasons are not readily identified.
