OBJECTIVES
The influence of CD34⁺ cells on transplant outcomes following hematopoietic stem cell transplantation remains controversial. A minimum of 2.0 to 2.5 million CD34⁺ cells/kg of patient weight is requested for a rapid and durable engraftment. The aim of this study was to detect the ratio of CD34+ B-lymphoid progenitors (hematogones) in bone marrow grafts and investigate their effects on hematopoietic recovery after transplant.

MATERIALS AND METHODS
Our study included 41 patients who received a bone marrow graft from their HLA-matched donor from 2016 through 2019. The CD34⁺ cell numbers within the graft were detected using Stem-Kit (Beckman Coulter). The ratio of CD34⁺ hematogones was determined either by their light scatter characteristics or by the detection of CD34, CD19, or CD10 coexpressing cells in a separate tube.

RESULTS
The median number of CD34⁺ cells was 5.9 × 106/kg (0.8-14.3 × 106/kg). The CD34⁺ cells consisted of 71% (range, 35.7%-100%) and 29% (range, 5.7%-64.3%) myeloid and B-lymphoid progenitors, respectively. Percentage of CD34⁺ (P < .001) and total (P < .001) hematogones in correlation with donor age. Time of neutrophil engraftment was significantly longer (P = .039) when total infused CD34⁺ cell content was <3 × 106/kg.

CONCLUSIONS
A remarkable population of hematogones within the CD34⁺ cell pool was detected in bone marrow grafts. Detection of the ratio of hematogones and most primitive stem cells (CD34⁺CD90⁺CD38⁻) may overall provide more information to build a better correlation between CD34⁺ cell content and the recovery of bone marrow.


Tourism is in need of new technologies, such as Augmented Reality (AR) to provide enhanced tourist experiences; hence, much research focuses upon this potential. At the same time, sustainability is considered among the most important topics within the tourism domain and the use of information technologies for tourism sustainability has emerged as a research area within the last six years (Ali & Frew, 2010). However, currently few studies explore the use of AR technology in improving and increasing tourism sustainability. Sustainability plays a particularly important role for cultural heritage tourism attractions, which are dependent on their natural environment, cultural and social traditions (Barthel-Bouchier, 2012; Prentice, 1993). One example of such an attraction is Geevor Tin Mine Museum, a UNESCO world heritage site located in Cornwall. Therefore, the present study aims to use the case of Geevor Tin Mine Museum to identify a number of ways AR implementation could positively contribute to increased attraction sustainability.

In mid May,1996, a leak was developed in a 24 crude oil line which transfers the untreated crude oil from El-Morgan field at Gulf Of Suez to the onshore process facilities. The line was installed in April, 1993 from carbon steel, API-5L XS - 60, tubing with wall thickness 0.75 inch. A diving survey was carried out after oil spill using side scan sonar survey and an Remote Operating Vehicle ( R.O.V ) video inspection identified the leak to be due to internal corrosion in 8 joints located at depth 240 - 250 feet. After fixing the leaks, complete ultrasonic survey was performed using high resolution intelligent pig. The ultrasonic data with the sample analysis of the deposits accumulated a head of the pig confirmed the mode of corrosion as internal Microbial Influenced Corrosion ( MIC ) in 6 o'clock position. A comprehensive review of the corroded line history and the available corrosion monitoring data and the applied corrosion mitigation program refereed to the following: 1- Corrosion monitoring using weight loss coupons, electrochemical devices, and /or chemical methods installed in the two ends of the subsea pipelines does not shows any sign of high corrosion rate (average 3 MPY ). 2- Absence of frequent pigging process in the pipeline resulted in accumulation of sludg that caused under deposits corrosion. 3- Thermophilic SRB bacteria was not detected, however some non SRB's were detected. This paper reviews in details the pipeline history, corrosion mechanism,inspection outlines, reservoir souring modeling and presents action plan to prevent this leak to happen again in future, with a brief introductory for mitigation options strategies and economics


This article examines the course and ways through which racial, ethnic characteristics are produced and circulated in the forms of the images of "successful Korean Americans" and "recent immigrants" in the New York Korean community in the early 2000s. The Korean community discourses produce and circulate various and conflicting images of Korean American lawyers while the lawyers` talk creates the negative images of their immigrant clients. Despite the common understanding of the legal profession as a successful career, Korean ethnic lawyers are often negatively viewed as incapable compared to "American" lawyers. In fact, conflicting and contradictory images of Korean ethnic lawyers reflect the coexistence of two different community discourses: the strengthening of Korean ethnic solidarity and the achievement of Americanization as a way of social mobility. These community discourses reinscribe the racial, ethnic marking of Korean American lawyers by imposing two incompatible demands on them. In contrast, the lawyers` talk formulates the images of Korean immigrants as undermining Korean legal professionals` integrity and as cultural others to American society. The lawyers try to socially and psychologically distance themselves from coethnic immigrants to some degree. However, they cannot ignore the fact that their main clientele consist of coethnic immigrants. The diverse and disparate images of Korean ethnics show that the New York Korean community is an ethnic space restricted by structural barriers such as race, immigration and the stratified professional service market.


Abstract The effects of temperature, chloride content, and dissolved oxygen content on the susceptibility to stress corrosion cracking (SCC) of type 304 stainless steel in high-temperature water have been investigated. Both U-bend and slow strain rate stress corrosion tests were performed, complemented by electrochemical polarization curve measurements and extensive oxide film analyses by Auger electron spectroscopy (AES). The U-bend data showed decreasing susceptibility to cracking with increasing temperature, which correlated with thicker oxide films and greater enrichment of chromium in the films. In contrast, the slow strain rate tests (SSRTs) indicated maximum susceptibility to cracking at 250°C in the temperature range 200 to 300°C and the susceptibility to cracking increased with increasing oxide thickness. The extent of chromium and nickel enhancement in the oxide layers were different for the two specimen types tested in equivalent environments. Greater enhancement of nickel occurred in films for...


This proceedings, "Engineering Mechanics: Proceedings of the 10th Conference", contains papers presented at the Conference held in Boulder, Colorado, May 21-24, 1995. The purpose of the Conference was to examine current knowledge and recent advances in mechanics as applied to the various fields in civil engineering. With this in mind, papers covered diverse topics such as computational mechanics, dynamics, elasticity, experimental analysis and instrumentation, fluids, granular flows, inelastic behavior, probabilistic methods, and turbulence.


Residual value or yield analysis is an advanced method of real estate valuation, applicable in a limited number of cases only. Its biggest problem is the quality of the input data. Less than critical use of the input data may lead to a completely wrong assessment. Therefore, the purpose of the thesis is to analyse in detail the residual method as a residual values as well as residual yield method. The aim of the survey is to determine the adequacy of the method in evaluating the performance real estate investments in the Republic of Slovenia. The underlying hypothesis posited is: the residual method is more useful in assessing real estate investments in real estate compared to real estate valuation. Research issues related to this hypothesis are: (a) how to increase the usefulness of the residual method? (b) how to improve the volume (the perfection of covers) and the quality of the data in order to increase the reliability of the estimates, based on the residual method? (c) Which information bases would need to improve the quality of the results obtained on the basis of the residual method? Hypothesis and the question of the proper method are the basis of the work presented here. First, the existing research areas under consideration were analysed and a critical analysis of the residual method and the necessary data for it performed. The next step was an analysis of the relationship between the prices of housing and the land and the construction costs, on the basis of which we could prove that the method is less adequate in periods of unstable real estate market. The survey of the factors affecting the use of the methods of the balance was made by means of a questionnaire. The survey involved 89 respondents. The conclusion is that the residual method has in practice been rarely used for real estate valuation and proved more suitable when assessing the investor's value. Two detailed examples of the application of the residual method are included. Based on the past and current research we can conclude that the residual method is a better choice when assessing the yield of the real estate investment than when determining its value.


DOI: 10.46998/IJCMCR.2021.15.000359 Abstract Pregnancy can increase the incidence of diffuse intravascular coagulation during hemangioma. In the present case a diagnosis of an adult multiple cutaneous hemangioma during pregnancy was made. We were not able to identify a similar case in the very sparse literature on this disease with chronic diffuse intravascular coagulation delivered by vaginal. Here, we report a patient who experienced chronic diffuse intravascular coagulation during pregnancy. A 27-year-old female 37 weeks pregnant, presented with a chronic DIC demonstrated by pregnancy tests. She was delivered by vaginal at 39 weeks of gestation. Hormonal and vascular changes of pregnancy may exacerbate multiple hemangiomas. Patients with multiple cutaneous hemangioma should be closely monitored during and after pregnancy as increased incidence of DIC during pregnancy. Hemangioma with chronic DIC is not an absolute indication of cesarean section. And the choice of delivery method for such patients is still controversial.


Bolometric detectors based on epitaxial thin films of rare earth perovskite manganites have been proposed as total energy monitors for X-ray pulses at the Linac Coherent Light Source free electron laser. We demonstrate such a detector scheme based on epitaxial thin films of the perovskite manganese oxide material Nd{sub 0.67}Sr{sub x0.33}MnO{sub 3}, grown by pulsed laser deposition on buffered silicon substrates. The substrate and sensor materials are chosen to meet the conflicting requirements of radiation hardness, sensitivity, speed and linearity over a dynamic range of three orders of magnitude. The key challenge in the material development is the integration of the sensor material with Si. Si is required to withstand the free electron laser pulse impact and to achieve a readout speed three orders of magnitude faster than conventional cryoradiometers for compatibility with the Linac Coherent Light Source pulse rate. We discuss sensor material development and the photoresponse of prototype devices. This Linac Coherent Light Source total energy monitor represents the first practical application of manganite materials as bolometric sensors.


The usual practice in using a control chart to monitor a profile is to take samples from the process with fixed sampling intervals. This article considered the use of generalized likelihood ratio (GLR) chart with a variable sampling interval (VSI) to monitor simple linear profiles. The performance of the VSI GLR chart was compared with that of the GLR chart with a fixed sampling rate. The results indicated the superiority of the VSI GLR chart over all possible single step changes in the intercept, slope, and standard deviation. Also, an example was provided to explain the implementation of the VSI GLR chart.


Th e service centres have been playing an important role in the development of the rural areas by providing service facilities to the people of the neighbouring villages. It is a general perception that the service centres are acting as a liaison between the cities or large towns and the neighbouring rural areas. Th e y usually help to reduce the population pressure, congestion and other related problems in the city by controlling the rural-urban migration, besides providing employment opportunities, industrial products, market facilities and spreading new ideas. In this w ay the contribution of the service centers in the socio-econom ic upliftmant of the neighbouring areas cannot be overstated. In this part of the study, a brief analysis is offered on the role of service centers in the development of different secondary activities, agricultural practice and also on the life style in the neighbouring areas to carry out the analysis in a systamatic way. Eleven service centres with extensive influence zones are selected from different parts and their respective neighbouring areas are surveyed. Here, 'the neighbouring area' refers to the villages located around the centre up to 9Km from the boundary of the centre and it is the average size of influence zone in the study area. Again the neighbouring areas are divided into three zones viz, immediate (from centre boundary to 3Km), intermediate (3-6Km) and distant (6-9Km ) zone to study the variations in the pattern of the impact of different service centres on respective zones. From these zones, the necessary primary information has been collected through field survey and the secondary information has come from the Census of India and other official documents.

Anabolic androgenic steroids (AAS) are synthetic derivatives of testosterone. Testosterone and AAS are used clinically for the treatment of renal failure, anemia, growing deficiency in children, delayed puberty, and in case of some chronic weakness such as AIDS and cancer. According to surveys and media reports, the illegal use of these drugs to increase muscle size and strength is widespread. There is a growing body of evidence that AAS have positive anabolic actions on the musculoskeletal system, influencing lean body mass, muscle size, strength, protein metabolism, bone metabolism, and collagen synthesis. Skeletal muscle is a primary target tissue for the anabolic effects of AAS. Supraphysiological doses of testosterone administered to healthy young men over periods lasting 10-20 wk increase lean body mass, muscle size, and strength with or without exercise. The anabolic effect of testosterone is dose dependent, and significant increases in muscle size and strength only occur with doses of 300 mg and higher. The testosterone-induced increase in muscle size and strength is due to a dose-dependent hypertrophy that results from an increase in cross-sectional area of muscle fibers and an increase in myonuclear number. Evidence suggests that these morphometric effects are the result of a testosterone-induced increase in muscle protein synthesis. AAS also enhance collagen synthesis and increase bone mineral density. The anabolic effect of AAS is mediated primarily by androgen receptors in skeletal muscle. Testosterone has potent anabolic effects on the musculoskeletal system, including an increase in lean body mass, a dose-related hypertrophy of muscle fibers, and an increase in muscle strength. For Taekwondo athletes requiring speed and strength and men desiring a cosmetic muscle makeover, illegal steroids are a powerful lure, despite the risk of subjective side effects.


ABSTRACT Just as democratic politics changes, so does the perception about the parties out of which it is composed. This paper's main purpose is to provide a new and updated ideological classification of Brazilian political parties. To do so, we applied a survey to political scientists in 2018, asking them to position each party on a left-right continuum and, additionally, to indicate their major goal: to pursue votes, government offices, or policy issues. Our findings indicate a centrifugal force acting upon the party system, pushing most parties to the right. Furthermore, we show a prevalence of patronage and clientelistic parties, which emphasize votes and offices rather than policy.


The rapid progress of science and technology which has a serious impact on the community change is called as millennial era. The impact requires us to determine the right attitude and in accordance with the values of Islam by creating three balances; spirit, soul (ratio) and body. Surely it gives good impact for the children brains development. But in other sides the children tend to be lazy to study in the school and lazy to read a book which is the window of the world. While our school still use board marker, white board, table, and chair in which these are not so interesting for them in comparing with the many tools existing in the mobile full of colors. While studying in the school provides only two colors (black and white) whereas there are thousand colors in mobiles. Moreover, many apps on mobile are far from the educational character that is the main soul as Muslim.
A comprehensive and integrated learning method will be a solid foundation in straightening character in the millennial era, the need for teacher is to connect wisdom and blessings from God to students. The goal is that students have a good behavior in social life and fear of Allah S.W.T. Education is a help to awaken, arouse, grow, enable and empower students natural potential in having good character. Islamic education will give many stepping actions how to produce a good generation having good character gradually, from the education in pre-conception, post-conception, prenatal, and the post-natal education. There are five recommendations that Islam offer how to straighten the character i.e. knowing the good,  feeling and loving the good, acting the good, modelling and exemplary, the last is repentance or regret.


Introduction: One of the major concerns in laryngeal laser surgery is the risk of airway fire. The introduction ofwrapped tubes and metal tubes has reduced the fire hazards. However, these tubes are expensive and do not provide convenient access to the surgical field. There are few laboratory studies addressing the resistance of polyvinylchloride tubes against ignition in the given circumstances. Nevertheless, its safety should be approved in clinical practices. Materials and Methods: This retrospective studyevaluated the airway management on 1024 patients undergoing laryngeal laser surgery. The data collection included the information about the type of endotracheal tube (ETT), mode of ventilation, and airway hazards (e.g., tube ignition). Results: Polyvinylchloride tubes and conventional positive pressure ventilation was applied for most of the patients (84.1%). The tube cuff was pierced with laser beam in 22 cases (2.5%). However, there was no case of ETT ignition or airway fire. Conclusion: Polyvinylchloride tubes can be safely used in this subset of surgeries pending meticulous attention to the safety recommendations.


This paper proposes a conceptual model on the achieving of the manufacturing sustainability through an established performance measure so called Overall Equipment Effectiveness (OEE) based on literature study. It examines the measures of overall equipment effectiveness that consist of contributing factors, availability, performance, and quality; and the sustainable manufacturing components including environmental conservation, social efficiency, and economic vitality. The measures of the OEE are required some modification to enhance the accomplishment of the sustainability in manufacturing. Besides, the measures are nevertheless possible to improve productivity through the identification and elimination of manufacturing big loses. It can be used as an initial reference for manufacturers to consider overall equipment effectiveness to advance the goal of manufacturing sustainability.


The termination of a tedious labour by forceps is usually such a relief both to patient and attendant that it is not a matter of wonder if sometimes sufficient attention is not given to possible injury which may be inflicted on mother and child. Much has been, and is still being, written on this subject. No more excellent summary of the whole question is to be found than that in the American System of Obstetrics.1 Dr. J. G. Swayne, recently calling attention2 to some of these dangers, refers to the often overlooked risk of compressing the cord in cases where it is coiled round the neck, and advises the operator to be careful not to pass either blade of the forceps unnecessarily far. A new interest for English readers 3 is given to obstetric traumatisms by Dr. George H. Rohe, of Baltimore, who, in a


The invention discloses a communication safety protection method by means of a wireless public network. The method comprises the steps that a master station is isolated from a public network through a serial port power proprietary protocol; dispatch digital certificate authentication and transmission encryption are achieved on the master station and a substation; a safety gateway is additionally arranged; data received by the wireless public network are transmitted to an SCADA system through a communication interface. Meanwhile, a safety policy is adopted to limit the access range and resources. The TCP/IP network communication technology, the IPSEC safety tunnel technology and the USBKET encryption authentication technology are integrated, emergency recovery, temporary debugging and safety access with no power communication conditions are achieved on the condition that power system communication is abnormal, and a safe and reliable transmission channel is provided for power grid dispatch automation real-time data transmission. Safe running of a power system is ensured on the condition that existing application environment and software do not need to be changed. The communication safety protection method has the advantages that the step design is reasonable, safety protection measures are competent, working performance is stable and reliable, and the method is suitable for being popularized for industries.

Inspired by ideas presented in Pigou's 1927 book on Industrial Fluctuations, Pigou cycles refer to economic fluctuations that are driven by changes in firms' belief about the future profitability of current investment decisions. A recent literature has emerged exploring whether Pigou's ideas may offer a reasonable explanation to business cycle episodes (revival inspired in part by the episode of the tech boom-bust of the 1990s). This literature has many challenges: theoretical, conceptual, and empirical. For example, what is the source of the change in beliefs, what are the transmission mechanisms, and are such forces empirically relevant? One of the immediate and less obvious challenges of this literature is to identify environments in which such changes in beliefs can actually cause business cycles, that is, positive comovement between investment, consumption, and employment. Although such a possibility sounds very intuitive, it is nontrivial to build fully specified (and reasonable) dynamic stochastic general equilibrium models in which changes in fundamentals that affect the future profitability of current investment actually generate business cycle phenomena. In a recent paper, Den Haan and Kaltenbrunner (2009) have shown that news about future productivity growth can generate business cycle phenomena in an environment in which jobs are subject to matching frictions. However, their results are somewhat fragile since they depended on, among others things, assuming a high degree of intertemporal elasticity of substitution in consumption. In the current paper, Den Haan and Lozej examine whether extending the analysis of the earlier paper to an international setting allows Pigou cycles to emerge for more reasonable parameter values. The main result of the paper is to show that an

In this paper, we have described the derivation of the formula currently used in China for surface-wave magnitude determination at the Beijing Seismic Station. The following formula is used:Ms= log (A/T)max +σ(△).Taking the surface wave magnitude of the Pasadena Seismic station given by Gutenberg and Richter, as the standard magnitude, the calibrating function of the surface-wave magnitude σ(△) and formula for the Beijing Seismic Station has been derived by using the mean value of surface-wave magnitudes with the Pasadena standard from 6 well-known seismic stations in the world. The calibrating function σ(△) was determined empirically for distances A= 8°-130°as follows:σ(△) = (1. 66±0.09)log△°+ (3.50±0.14)In the epicentral distances △:=130°-180°, a modification is made for the absorption coefficient k, thus the formula of the calibrating function derived semi-empirically and semi-theoretically is expressed as follows:In order to improve the accuracy of the surface-wave magnitude determinations, the standard of the Beijing station is extended to be used in 12 basic seismic stations in China. The station correction of each seismic station has been calculated by using the data of 360 earthquakes, thus improving the consistency for determining the surface-wave magnitudes.


Journal Citation Reports, published by Thomson Scientific (http://scientific.thomson.com/isi/), has issued its first impact factor for Space Weather. The number is 1.610. I consider this to be very good, strongly validating the impact that Space Weather has already made in its short life within the community of Space Weather professionals. The impact factor for science and engineering publications is important for authors and readers of journals and related publications. The factor provides authors with a comparative measure of how many readers their papers can expect to attract and how their papers subsequently influence others' research. Readers of journals with high impact factors recognize that the papers they view likely represent high-quality, influential work. The impact rating for Space Weather is determined by the total number of citations in 2006 for articles published in 2005 and 2004 (when Thomson Scientific began monitoring Space Weather, 3 months after its launch) in the journal category of Space Weather divided by the total number of articles published in the category in 2004 and 2005. As readers know, Space Weather is an unusual journal in several respects and thus does not fit readily into the categories that Journal Citation Reports use. Space Weather is not a typical technical journal, but more of a technical magazine because it also includes features, news, opinions, and meeting reports as well as science papers. The magazine is also not purely a "geophysics" or an "astrophysics" or an "engineering" publication: The papers in Space Weather attempt to build bridges between the science of space research and the applications of this research. And, in addition to Space Weather being an online journal, a print digest (Space Weather Quarterly) is published each season with selected technical and news articles. The 2006 impact factor for Space Weather places it approximately in the median of impact factors for the three categories geochemistry and geophysics, astronomy and astrophysics, and meteorology and atmospheric sciences. As a relative measure, Space Weather's companion and preeminent geophysical publication, the Journal of Geophysical Research, has a 2006 impact factor of 2.800, and the factor for Geophysical Research Letters is 2.602. There are several technical publications with some overlaps with Space Weather's coverage and with which Space Weather might be considered to be competing. The 2006 impact factors for those publications that I have examined are a factor of 2–3 below the factor for Space Weather. The high regard for Space Weather by professionals is due to many things, not the least of which are you, the readers and contributors. Your contributions to the journal in terms of papers, commentaries, and suggestions have made Space Weather indispensable reading for professionals. Also important, the support and advice of the publication staff of the journal at AGU deserve special mention for Space Weather's success to date. Thank you to everyone who has helped make Space Weather a success.


Previous studies of the initial conditions of massive star formation have mainly targeted Infrared-Dark Clouds (IRDCs) toward the inner Galaxy. This is due to the fact that IRDCs were first detected in absorption against the bright mid-IR background, requiring a favourable location to be observed. By selection, IRDCs represent only a fraction of the Galactic clouds capable of forming massive stars and star clusters. Due to their low dust temperatures, IRDCs are bright in the far-IR and millimeter and thus, observations at these wavelengths have the potential to provide a complete sample of star-forming massive clouds across the Galaxy. Our aim is to identify the clouds at the initial conditions of massive star formation across the Galaxy and compare their physical properties as a function of their Galactic location. We have examined the physical properties of a homogeneous galactic cold core sample obtained with the Planck satellite across the Galactic Plane. With the use of Herschel Hi-GAL observations, we have characterized the internal structure of them. By using background-subtracted Herschel images, we have derived the H2 column density and dust temperature maps for 48 Planck clumps. Their basic physical parameters have been calculated and analyzed as a function of location within the Galaxy. These properties have also been compared with the empirical relation for massive star formation derived by Kauffmann & Pillai (2010). Most of the Planck clumps contain signs of star formation. About 25% of them are massive enough to form high mass stars. Planck clumps toward the Galactic center region show higher peak column densities and higher average dust temperatures than those of the clumps in the outer Galaxy. Although we only have seven clumps without associated YSOs, the Hi-GAL data show no apparent differences in the properties of Planck cold clumps with and without star formation.

Triangle counting is a graph algorithm that calculates the number of triangles involving each vertex in a graph. Briefly, a triangle encompasses three vertices from a graph, where every vertex possesses at least one incidental edge to the other two vertices from the triangle. Consequently, list intersection, which identifies the incidental edges, becomes the core algorithm for triangle counting. At the meantime, attracted by the enormous parallel computing potential of Graphics Processing Units (GPUs), numerous efforts have been devoted to deploy triangle counting algorithms on GPUs.While state-of-the-art intersection algorithms, such as merge-path and binary-search, perform well on traditional multi-core CPU systems, deploying them on massively parallel GPUs turns out to be challenging. In particular, merge-path based approach experiences the hardship of evenly distributing the workload across vast GPU threads and irregular memory accesses. Binary-search based approach often suffers from the potential problem of high time complexity. Furthermore, both approaches require sorted neighbor lists from the input graphs, which involves nontrivial preprocessing overhead. To this end, we introduce H-INDEX, a hash-indexing assisted triangle counting algorithm that overcomes all the aforementioned shortcomings. Notably, HINDEX achieves 141.399 billion TEPS computing rate on a Protein K-mer V2a graph with 64 GPUs. To the best of our knowledge, this is the first work that advances triangle counting beyond the 100 billion TEPS rate.


The optical properties of single Ag particles on an MgO thin film have been investigated with fluorescence spectroscopy performed in a scanning-tunneling-microscope setup. Depending on the point of excitation within the particle (top or side facet), two emission maxima are detected that are compatible with the in-plane and out-of-plane plasmons of the Ag deposits. The different excitation cross sections and spectral properties of the two modes give rise to characteristic intensity patterns in photon maps taken from individual particles.


Describes a self-contained CTD system to collect temperature and salinity profiles from vessels underway at speeds up to 20 knots. An internally recording CTD housed in a streamlined body is freely dropped on a tether line deployed at high speed. A prototype with 850 m of line has reached 370 m from a vessel travelling at 10 knots. A mathematical model predicts that with a suitable line, the following depths can be reached depending on the speed: 900 m at 14 knots, 600 m at 18 knots and 370 m at 22 knots. This system is suitable for operation with a minimum of human intervention even from vessels with very high freeboard. The ultimate goal is to develop a system in which the entire launch-deployment-recovery cycle will be initiated by a single signal from the bridge of the vessel.<<ETX>>

The invention relates to a method for controlling an automatic gearbox of a motor vehicle. An electronic gearbox control determines a transverse acceleration value (AQ) by means of signals that are proportional to the wheel speed (NRA3, NRA4). Said value is outputted to additional programme modules. The determined wheel speeds (NRA3, NRA4) which enter into the transversal acceleration value (AQ) are corrected by wheels of the vehicle in a tolerance balance module of the wheels (M1) when a dynamic tire radius (RDYN) at one of the wheels of the vehicle deviates from a tyre radius which is given at an optimum tyre geometry.

W e present results ofan extensive investigation ofthe physicalchanges taking place in the em ission regionsoftheLM XB X 1624-490 during strong aring in observationsm adeusing RXTE in 1997 and 1999.Based on the detailed light curve,we propose that the aring consists ofa superposition ofX-ray bursts.It is shown that m ajor changes take place in the blackbody em ission com ponent,the tem perature kTB B increasing to 2.2 keV in aring.Rem arkably,the blackbody area decreases by a factor of 5 in aring.D uring are evolution, theblackbody lum inosity rem ainsapproxim ately constant,constituting a previously unknown Eddington lim iting e ectwhich we propose isdue to radiation pressure ofthe blackbody askTB B increases a ecting the innerdisk or accretion ow resulting in a decreased em itting area on the star.W e argue that the large decrease in area cannotbeexplained in term sofm odi cation oftheblackbody spectrum by electron scattering in theatm osphere ofthe neutron star.The height ofthe em itting region on the nonaring neutron star is shown to agree with the heightofthe innerradiatively-supported accretion disk as found for sources in the ASCA survey ofLM XB ofChurch & Ba luci nska-Church (2001).The decrease in height during aring is discussed in term s ofpossible m odels,including radialaccretion ow onto the stellarsurface and the theory ofaccretion ow spreading on the neutron starsurface ofInogam ov & Sunyaev (1999).W e dem onstrate thatthe intensity ofthe broad iron line at 6.4 keV isstrongly correlated with the lum inosity ofthe blackbody em ission from the neutron star,and discuss the probable origin ofthisline in the AD C.Finally,possible reasonsfornon-detection ofa re ection com ponent in thissource,and LM XB in general,are discussed.


Parametric resonance spectra of radicals produced by 1.6-Mev electrons and the kinetics of their accumulation were investigated in order to determine the properties of radicals formed in the radiolysis of aromatic hydrocarbons. The spectra of benzene. diphenyl, n-terphenyl, and n-ditolyl were determined at -- 124 and --33DEC. (R.V.J.)


We have updated predictions for high energy neutrino and antineutrino charged current cross-sections within the conventional DGLAP formalism of NLO QCD using a modern PDF fit to HERA data, which also accounts in a systematic way for PDF uncertainties deriving from both model uncertainties and from the experimental uncertainties of the input data sets. Furthermore the PDFs are determined using an improved treatment of heavy quark thresholds. A measurement of the neutrino cross-section much below these predictions would signal the need for extension of the conventional formalism as in BFKL resummation, or even gluon recombination effects as in the colour glass condensate model.


We present a self-consistent, semi-analyticalCDM model of star formation and reioniza- tion. For the cosmological parameters favored by the WMAP data, our models consistently reproduce the electron scattering optical depth to reioniz ation, redshift of reionization and the observed luminosity functions (LF) and hence the star formation rate (SFR) density at 3 ≤ z ≤ 6 for a reasonable range of model parameters. While simple photoionization feed- back produces the correct shape of LF at z = 6, for z = 3 we need additional feedback that suppresses star formation activities in halos with 10 10 . (M/M⊙) . 10 11 . Models with prolonged continuous star formation activities are prefer red over those with short bursts as they are consistent with the existence of a Balmer break in considerable fraction of observed galaxies even at z ∼ 6. The halo number density evolution from the standardCDM structure formation model that fits LF up to z = 6 is consistent with the upper limits on z ≃ 7 LF and source counts at 8 ≤ z ≤ 12 obtained from the Hubble Ultra Deep Field (HUDF) observations without requiring any dramatic change in the nature of star formation. However, to reproduce the observed LF at 6 ≤ z ≤ 10, obtained from the near-IR observations around strong lensing clusters, we need a strong evolution in the initial mass func tion, reddening correction and the mode of star formation at z & 8. We show that low mass molecular cooled halos, which may be important for reionizing the universe, are not detectabl e in the present deep field obser- vations even if a considerable fraction of its baryonic mass goes through a star burst phase. However, their presence and contribution to reionization can be inferred indirectly from the redshift evolution of the luminosity function in the redshi ft range 6 ≤ z ≤ 12. In our model calculations, the contribution of low mass halos to global SFR density prior to reionization reveals itself in the form of second peak at z ≥ 6. However this peak will not be visible in the observed SFR density as a function of z as most of these galaxies have luminosity below the detection threshold of various ongoing deep field survey s. Accurately measuring the LF at high redshifts can be used to understand the nature of star formation in the dark ages and probe the history of reionization.


A comparison of ordinary membrane machines, understood as certain recursive families of deterministic P systems, with some other mathematical models of systems realizing massively parallel computations is discussed. These mathematical models are those which respect recursiveness of computational tasks of systems, i.e., the functions to be computed are recursive functions and the decision problems correspond to recursive sets. The comparison together with open problems is summarized in the enclosed tables, where open problems are indicated by question mark "?".


Bashar al-Assad`s ascent to power following the death of his father, Hafiz al-Assad, on June 10, 2000, surprised no one. President Assad decides to make Bashar his heir from mid-1990`s. Initially he was not thought of as his father, Hafez al-Assad`s successor. This was a role originally filled by his brother Basil who died in an accident in 1994. At his father`s request, Bashar returned to Syria to begin his political and military career. First, Bashar sought to build up his political supporter within the military and security apparatus. Second, he sought to build up his standing with the Syrian public and abroad. He began to involve in the diplomatic arena, especially Lebanon issues. When Hafiz al-Asad died on 10 June 2000, Bashar`s succession went smoothly on the surface. But the political and military elites of Asad`s generation still controls Syria. They had complaints about Bashar`s weak leadership and lack of experience. And their values and world view are obstacles of Bashar`s policies for political and economic reforms. During his first years in power, Bashar was anxious to maintain the political system which his father had established in Syria and not make substantive changes in it. Because his political base was not strong enough. However, by cabinet reshuffle on December 2001, Bashar appointed new political elites who carry his reform policies. Then he press retirement some of old elites. By gradually changing inherited political and military elites to his new elites, he succeeded to make his own regime not his father`s. And he started to carry his own policy toward political and economic reforms with his new elites. But Bashar`s reforms was not successful because his regime is not stable completely and international circumstance is unstable.


In this paper, we examine code-aided synchronization in the presence of carrier frequency uncertainties and phase noise. As code-aided synchronization can only achieve high estimation accuracy if the initial parameter offset is sufficiently small, we employ a data-aided coarse synchronization unit comprising a feed-forward frequency estimator and a LMMSE estimator for pre-compensating frequency offsets and phase noise. Furthermore, we make use of known iterative synchronization techniques for frequency and phase offsets. We here extend the concept of iterative synchronization to iterative phase noise compensation and we show analytically under which circumstances our approach can achieve a worthwhile improvement in terms of estimation accuracy.


In this paper, a Lagrangian-based dynamics is employed for a Twowheeled Inverted Pendulum with the consideration of unknown matched and unmatched uncertainties which are bounded by known nonlinear functions. The model is linearised and further transformed into a regular form to facilitate the analysis and design. A sliding surface is designed, and a set of conditions is developed such that the resulting sliding motion is uniformly ultimately bounded from a practical perspective. Further, a sliding mode control scheme is proposed such that the system is driven to the sliding surface in finite time and maintained on it thereafter. Finally, both simulation and experiment are presented using practical model parameters data to demonstrate the effectiveness and robustness of the regulation control.


The generation of macroscopic and spatially separated three-mode entangled light for triply coupled {chi}{sup (3)} Kerr coupler inside a pumped optical cavity is investigated. With the linearized analysis for small perturbation around the steady state of the pumped cavity modes, the linearized Hamiltonian and the corresponding master equation are obtained. It is found that the bright three-mode squeezing and full inseparable entanglement can be achieved both inside and outside the cavity.


Nanocomposites based on high impact polystyrene (HIPS) and silver nanoparticles (AgNPs) were synthesized via in situ bulk-suspension polymerization adding a colloidal suspension of AgNPs in styrene from the beginning of the reaction. The concentrations of AgNPs in the final nanocomposites were 0, 0.025, 0.10, and 1.0 wt%. The rate of polymerization and free radicals concentration were found to decrease with increasing AgNPs concentration. For nanocomposites with 0.025 and 0.10 wt% of AgNPs, the phenomenon of phase inversion (PI) during the mass polymerization occurred within the same range as that for the blank HIPS. Further, the impact strength of these nanocomposites did not present any changes as compared to the blank HIPS. However, there was no sign of the PI phenomenon in the case of 1.0 wt% of AgNPs, due to a decrease in the amount of free and graft polystyrene onto the rubber chain as the free radicals concentration diminishes with an increase in AgNPs. In this case the impact strength doubles the values of the blank HIPS due to the presence of a interpenetrated polymer network of crosslinked grafted rubber and polystyrene (PS) instead of the formation of a defined morphology.

The light spectra that reach plants change across different shading conditions, may alter the pattern of nitrogen (N) uptake and assimilation by understory regenerations that are also exposed to N deposition. We conducted a bioassay on Chinese cork oak (Quercus variabilis Blume) seedlings subjected to five-month N pulsing with 15NH4Cl (10.39 atom %) at 120 mg 15N plant-1 under the blue (48.5% blue, 33.7% green, and 17.8% red), red (14.6% blue, 71.7% red, 13.7% green), and green (17.4% blue, 26.2% red, 56.4% green) spectra provided by light-emitting diodes (LEDs). Half of the seedlings were fed twice a week using a 250 ppm N solution with added phosphorus, potassium, and micro-nutrients, while the other half received only distilled water. Neither treatment affected growth of height, diameter, or leaf area. Compared to the red light spectrum, the blue light treatment increased chlorophyll and soluble protein contents and glutamine synthetase (GS) activity, root N concentration, and N derived from the pulses. The green light spectrum induced more biomass to allocate to the roots and a higher percentage of N derived from internal reserves compared to the other two spectra. The 15N pulses demonstrated no interaction with spectra but weakened the reliance on N remobilization from acorns, strengthened biomass allocation to shoots, and induced higher chlorophyll content, GS activity, and N concentration. In conclusion, the red light spectrum should be avoided for Q. variabilis regenerations whose biomass allocation to underground organs are weakened under this condition.


Building on Dixit & Pindyck (1994) model for determining investment timing, this paper develops a real options framework to understand how and when Entrepeneurs seek for Venture Capital financing. The setting comprises an established start-up firm which is deciding between a small and a large expansion project. The Entrepeneur will be seeking Venture Capital financing to carry a larger expansion whether this outprofits the smaller expansion, even at the expense of a lower equity stake. An extension has been designed assuming that the expansion expenditures are divisible and that post-expansion profit is a function of the overall capital expenditure.

with revolution head-on. As cofounder of the Mosireen Collective, a media enterprise that archived and documented the Egyptian revolution, Hamilton played an integral role during the uprising of Tahrir Square, writing a series of pieces about his experiences for the Guardian and producing a trove of harrowing, vital mini-documentaries about the uprising that are still available online. The City Always Wins is set in Cairo in 2011, shortly after Hosni Mubarak has been ousted from power, and is divided into three sections— the first and third taking place in 2011 and 2012, respectively, the second taking place in 2013, before and after the overthrow of Mohamed Morsi, Egypt's first democratically elected president. Paced like a thriller and split into oneto five-page chapters, the story is narrated by a host of voices and freewheeling points of view that give it the feel of a frenetic communal diary from the front lines. The two voices that dominate the narrative belong to Mariam and Khalil—she the daughter of two well-known Egyptian doctors, he a Palestinian American fixer for Western journalists. The two meet while being chased by men in balaclavas, and soon thereafter form a start-up media company called "Chaos"—aptly titled, as Mubarak warned that Egypt would "sink into chaos" if he left his post early—that does activist work for the revolution, gathering content for a podcast, magazine, and website. They and a pack of others—some Ph.D. dropouts, some nurses, C R I T I C I S M


Introduction To date, there are no reports of widespread failures of pyrethroid insecticides to control the corn earworm, Helicoverpa zea (Boddie) (Lepidoptera, Noctuidae), in midwestern North America. However, observations of decreased effectiveness of pyrethroids in small-plot insecticide evaluations, lower-thanexpected mortality in adult bioassays using diagnostic doses of pyrethroid insecticides, and scattered control failures in commercial sweet corn fields lead to the inference that H. zea resistance to pyrethroids is a potential problem in the midwestern United States and southeastern Canada. Sweet corn, seed corn, tomatoes, and peppers are among the crops most often protected from H. zea by applications of pyrethroids. If resistance compromises pyrethroid effectiveness, adopting or developing alternative management practices will be essential. This paper summarizes the current status of management alternatives for H. zea, specifically in commercial production of sweet corn, seed corn, tomatoes, and peppers.


The deposits formed on filter elements designed to remove particles from the gas stream in coal-fired power systems can lead to catastrophic failure of the filter elements and damage to the system. These deposits are formed at temperatures between 350 and 900 C and, over time, densify and become difficult to remove. This decreases the permeability of the filter system and, in some cases, can lead to the fracturing of the filter membrane, exposing downstream components to hazardous particulate loadings. This paper presents data on the surface analysis of deposits formed in laboratory and full-scale tests of the durability of ceramic candle filter elements. Auger electron spectroscopy is used to determine the variations in surface chemistry of the deposits. The data present the possibility of surface segregation or fluxing of some chemical species on the surface of the ash particles. These data suggest possible mechanisms for the propensity of the ash to agglomerate at these temperatures.


Despite the similarities and possible existence of a common source, the B. N. Nouv. Acq. Fr. 15771 and the B. N. Fr. 9223 are two collective lyrical anthologies that have not been copied out one over the other. They offer us an aspect of what Breton poetry was like in the French language in the middle of the fifteenth century. The second part of the B. N. Fr. 9223 bears upon an important account of poetic activity in Jacques de Luxembourg-Richebourg's milieu. The first stage of our study, is the influence that had been practiced by Charles d'Orleans throughout poems known as "de concours". The thematic evolves around two axes: that of purely conventional love and that of disenchanted love which seems to have been more and more inspired by reality which, in turn, find their means of expression through the systematic use of "equivoquee" rhyme, "derivative" rhyme and through the use of accumulatory ("accumulation") and contrapuntal ("contradiction") elements. Love and despair are almost consubstantial. In these "livres d'amour" death appears to be but an accessory, like a commonplace ornament. The "Debat du jeune et du vieux" as well as the "Debat de Vie et de Mort " that encompasses short poetry have acquired a different approch. Blosseville, Vaillant, Antoine de Cuise and Jacques de Luxembourg-Richebourg are amongst the poets that are the most represented in the anthologies mentioned above.

Four vehicular crash tests conducted on metal beam guardrail envelopes called "bullnose barriers" are reported. Large size passenger cars weighing about 4,900 lbs (2,220 kg) impacted the barriers at speeds of 41 to 64 mph (18 to 29 m/sec). In three tests the vehicle impacted the nose of the barrier head-on, and in the last test it struck the nose in a 10 deg/18 in. off-center attitude. The barriers consisted of two flared sides of W-section guardrail joined at one end by a curved section with about a 5 foot (1.5 m) radius. The barriers were supported by wood posts and anchored with cables at the front and back of each flared side of the barrier. Some designs also included the following features: breakaway cable anchors, different post sizes, torsional post reinforcement, concrete footings, and a secondary cable restraint system. A bullnose design capable of stopping and containing a 60 mph (27 m/sec) head-on impact at low deceleration with no intrusion of barrrier or vehicle components into the passenger compartment and little barrier debris was developed. However, a high speed vehicle impacting off-center at an angle into a similar barrier rode down the front of the barrier without being stopped or contained. Recommendations for further testing and suggested design changes are included to improve the capability of the barrier for off-center angular impacts.


A study was conducted with one inorganic and two organic sources of nitrogen to assess their performance towards sustainability of upland agriculture in hills of Uttaranchal. For this, the nutrient sources were applied to the wheat crop and ragi (locally known as mandua) was taken on residual fertility. After three years of experimentation, it was found that all sources were equally effective in influencing yield of wheat; however, residual effect of organic sources was prominent in affecting the ragi yield. The soil properties also improved under organic nutrition.

Objective To investigate the expression of A-type potassium channel Kv4.1 in the CA1,CA3 and DG regions of the hippocampus in rats with pentylenetetrazol(PTZ)-induced epilepsy.Methods Forty SD rats were randomly divided into normal control and epilepsy groups(including 3 subgroups: 1,24 and 72 hrs after the epilepsy events).Epilepsy was induced by injecting PTZ.Kv4.1 protein was detected in the CA1,CA3 and DG regions of the hippocampus using immunohistochemical and Western Blot analysis.Results The Kv4.1 protein expression in the hippocampus in the epilepsy groups was significantly higher than in the control group(P0.05).There were no significant differences in the expression of Kv4.1 protein among the three epilepsy subgroups.Conclusions The expression of A-type potassium channel Kv4.1 protein in the hippocampus of epileptic rats increased,and the increased expression of Kv4.1 might play a role in the pathogenesis of epilepsy.


IoT devices are becoming ubiquitous, spreading in several technological fields. Because of their remote collocation, their usefulness profits of power supplies based on energy harvesting techniques, rather than batteries. Vibration Energy Harvesters (VEHs) based on magnetostrictive alloys are promising because of their excellent characteristics, but the available vibrations are such that the exploitable output voltages are lower than the standards 1.6, 3.3 and 5 V. Then, an electronic circuitry is necessary to increase the output DC voltage and improve their efficiency. Conversion methods have been presented over the years for other smart devices based on piezoelectrics. However, very few or none are specialized for magnetostrictive ones. A promising technique for the latters can be a direct AC-DC Boost conversion. This paper presents the design and control of such a circuit, driven with a real-time operating Arduino board, able to self-adapt with respect to the incoming time period. Several experimental tests are presented, showing the potentiality of the circuit.

We investigate whether smartphones can be used to distinguish different users based on their gait, the rhythmical body movements of human beings as they walk. To this end, we propose, describe, and experimentally evaluate a system that classifies peoples' gait patterns using the tri-axial accelerometer of the Motorola Droid phone. The system employs the wavelet transform to extract features from raw acceleration data and the k Nearest Neighbors (kNN) algorithm to perform the classification. Preliminary experimental results show that the system achieves high classification rates (i.e. above 90%) when users walk at approximately constant speeds regardless of variations in environment. Our results show promise toward using gait as a means of user recognition. A version of this paper appeared in M. Boyle, A. Klaustner, D. Starboinski, A. Trachtenberg, and H. Wu Poster: gait-based smartphone user identification, Proceedings of the 9th international conference on Mobile systems, applications, and services (MOBISYS '11), Bethesda, Maryland, USA, 2011, pp. 395-396.

Abstract : We showed that the G-protein activator lysophosphatidic acid (LPA) triggered actin reorganization followed by ACh release in nerve growth factor treated PC12 cells, and that BoNT/A blocked both events through degradation of RhoB by the proteasome. Overexpression of wild-type RhoB caused to overcome toxin s inhibitory effect on actin reorganization/exocytosis stimulated by LPA. A knockdown of the RhoB gene via targeted siRNA transfection resulted in total inhibition of both actin reorganization and ACh release induced by LPA. We conclude that the RhoB signaling pathway regulates ACh release via actin cytoskeletal reorganization, and that botulinum toxin inhibits neuroexocytosis by targeting RhoB pathway.

Purpose : This study was performed to analyze the frequencies of peripheral IFN- γ-producing cells at the single cell level, and to determine concentrations of circulating interferon- γ(IFN- γ) in the acute and subacute phases of Kawasaki disease(KD). Methods : Ten patients with KD were studied and seven healthy children were selected as control subjects. Using immunofluorescent detection of intracellular IFN- γ in CD4(+) and CD4(-) the cells, the frequencies of IFN- γ-producing cells in peripheral blood mononuclear cells(PBMC) were studied. Circulating IFN- γ levels were measured by enzyme-linked immunosorbent assay. Results : The frequencies of peripheral blood CD4(+) and CD4(-) IFN- γ-producing cells in acute phase KD patients were significantly lower than in subacute phase KD patients and control children(P<0.05). CD4(-) cells, thought to be mainly composed of CD8(+) cells, appeared to be more responsible for the reduced frequencies of total IFN- γ-producing cells than CD4(+) cells. There were, however, no differences in frequencies of IFN- γ-producing cells between KD patients in the subacute phase and control group children. In contrast, serum IFN- γ levels were higher in KD patients in the acute phase than in the subacute phase(P<0.05). Conclusion : The above results show an increased level of circulating interferon- γ and a decreased emergence of peripheral IFN- γ-producing cells in acute KD patients, suggesting transient infiltration of activated IFN- γ-producing cells into the inflammatory sites during acute KD. These findings also support the hypothesis that IFN- γ plays an important role in the pathogenesis of KD-related vasculitis. (J Korean Pediatr Soc 2000;43:1350-1355)

ten by Doug Carnine from the University of Oregon. It is a cliche to say that a prominent professional needs no introduction, but this is certainly the case with Dr. Carnine. His contributions to the field, particularly in instructional methodology, have been immeasurable. Numerous best practices in the field in direct instruction, curricular modifications, and content instruction for older students derive from his outstanding work. In this Perspective, he challenges us to accept the responsibility of moving education forward by doing more than paying lip service to the translation of research into practice .— EAP


In this paper,the model of YGG type steel wire rope shock-isolation system with single degree of freedom is introduced,and the energy response equations are derived.By solving the equations,the transfer,dissipation and distribution of the energy are obtained when the system is excited by shock loads.The principle of passive shock isolation of YGG type steel wire rope shock-isolation system is revealed from the viewpoint of energy.Based on the analysis of the results,the influence of input total energy,pre-compression,weight quota and axial force on the energy distribution and the energy dissipation characteristics of the steel wire rope shock-isolators is discussed.The axial and lateral energy-dissipation abilities of YGG-8kN steel wire rope shock-isolator are obtained.This work provides a reference for theoretical study on the entire shock isolation,efficiency evaluation,technique and design study in explosion and shock environment.


About 25 years ago, the analytic world witnessed a sharp debate provoked by Roy Schafer over the 'scientific' status of psychoanalysis. Schafer's case – argued with a formidable range of philosophical and literary equipment – was that analysts had forgotten the essence of their practice,


An experiment laid out in split plot design replicated four times consisted of 12 treatments, having two FYM levels i.e., FYM (10 t/ha), no FYM and six foliar nutrition (0.1% calcium chloride, 0.5% zinc sulphate, 2.0% potassium chloride, 20g/ha ethylene synthesis inhibiter 1- methyl cyclo propane (1-MCP) and water spray at post anthesis stage) along with control as no foliar spray. Soil Appication of 10 t FYM /ha resulted numerically higher value of soil moisture content at different growth stages, emergence count, dry matter, LAI, yield attributes and ultimately grain yield. Physiological response of wheat in terms of chlorophyll content (SPAD value), photosystem II efficiency (Fv/Fm), canopy temperature, leaf temperature and transpiration rate were also numerically superior with FYM application over no FYM application. However values of aforesaid parameters except canopy temperature at 90 and 110 days after sowing were statistically at par. All foliar spray treatments were numerically superior over no foliar spray. However foliar spray of Zinc sulphate (0.5%) at post anthesis resulted highest yield attributes and grain yield and significantly superior to no spray. Among all treatments, FYM+ZnSO4 gave highest cost of cultivation, gross return and net return. There was not significant interaction between FYM and foliar treatments with respect to all the aforesaid parameters.


The surfeit of generic and place-specific sounds that exist in the urban environment contribute to what has been referred to as the soundscape. Within the built environment sound has the potential to create thresholds and acoustic territories that define and colour the experience and social functioning of inhabited spaces. In this research, a robust critical examination of the literature by prominent sound artists and theorists is used to illustrate how sound contributes to the urban experience. This is reinforced by primary research undertaken in the city of Edinburgh where the analysis and synthesis of these secondary sources is tested using bespoke soundworks to determine the ways in which sound contributes to our perception, reading and understanding of our physical environment. This research concludes by illustrating the potential for the future, technological development of the soundscape.


Macroporous silicon membranes are fabricated whose pores are terminated with 60 nm thin silicon dioxide shells. The transmission of electrons with energies of 5 kV-25 kV through these membranes was investigated reaching a maximum of 22% for 25 kV. Furthermore, the transmission of electromagnetic radiation ranging from the far-infrared to the x-ray region was determined. The results suggest the application of the membrane as window material for electron optics and energy dispersive x-ray detectors.


The cultural politics perpetrated by Mussolini especially in musical field might appear as a janus bifrons: on one hand, a "revolutionary" character was shown not only in familiar-like relationships with some of the most prominent composers of the Italian musical panorama, ideally devoted to celebrate the imperial glories (Mascagni, Pizzetti, Malipiero, Casella) – but also in the exaltation of the instrumental music rather than the operatic one and in the controversial exchange with the futuristic avantgarde (Russolo, Petrella). On the other hand, a "conservative" character may be detected in submitting the artistic creativity to the censorship and setting the musician again at the service of a chief. Though divergent, such attitudes come to a synthesis, imposed by the centripetal force that attracted towards the leader, a sort of gravitational camp where most of the Italian musicians fell, as a true reflection of the society at that time. As H. Sachs wrote, "study of Italian music under fascism reveals a picture of workaday infighting and intrigue in abundance, much grotesque opportunism, occasional examples of naive good faith in the government, and very little real political opposition" (Sachs, 1987, p.10). By tracing the correspondence between Mussolini and the composers of the regime according to the fundamental study by Fiamma Nicolodi, this paper aims at illustrating how the regime was able to benefit from music as the main means of popular consensus.


Abstract. This research is exploratory descriptive which aims to explore knowledge for the introduction and understanding of a phenomenon whose information is still lacking. The subjects of this study were plants from the Solanaceae, Malvaceae and Asteraceae tribes which were considered cosmopolitan. Research activities carried out through three stages, namely the preparation phase, the implementation phase and the final stage. In the preparation stage, research tools and materials are provided. The implementation stage is the observation of trichomes in plant specimens using a digital monopod microscope. In the final stage, identification of the types of trichomes possessed by the research materials and the preparation of trichome practicum guides in dicotyledonous plants based on the work steps carried out during the study. Based on observations there are 12 types of plants from the Solanaceae, Malvaceae and Asteraceae tribes which can be recommended as ingredients for the practice of trichome in plant anatomy material.Keywords: guide, trichome, exploration, practicum.


Vegetation ecologists and soils scientists frequently use moving split-window analysis for partitioning transect data, and reveal boundaries. Few existing softwares supported this research activity, but non of them was equipped with statistical significance test. A new software was developed to mitigate this shortcoming. We offer a user-friendly tool with five distance/dissimilarity functions and two types of random reference. This paper is a short description of the program.


Subdwarf B (sdB) stars are core helium-burning stars with stratified atmospheres. Their atmospheres are dominated by hydrogen (H) while the helium (He) and metal abundances are shaped by an interplay of gravitational settling and radiative levitation. However, a small fraction of these show spectra dominated by He I absorption lines. In between these groups of He-deficient and extreme He-rich sdBs, some are found to have intermediate surface He abundances. These objects are proposed to be young "normal" (He-deficient) sdBs for which the dynamical stratification of the atmosphere is still ongoing. We present an analysis of the optical spectrum of such an intermediate He-rich sdB, namely CPD-20°1123, by means of non-local thermodynamic equilibrium (NLTE) stellar atmosphere models. It has a He-to-H number ratio of $\mathrm{He/H} = 0.13 \pm 0.05$ and its effective temperature of $T_\mathrm{eff} = 25\,500 \pm 1\,000$ together with a surface gravity of $\log\,(g\,/\,\mathrm{cm}/\mathrm{s}^2) = 5.3 \pm 0.3$ places the star close to the high-temperature edge until which it may be justified to use LTE model atmospheres. This work states a test of the Tubingen NLTE Model Atmosphere Package for this temperature regime. We present the first application of revised, elaborated model atoms of low ionization stages of light metals usable with this atmosphere code.

Record‐breaking temperatures attract attention from the media, so understanding how and why the rate of record breaking is changing may be useful in communicating the effects of climate change. A simple methodology designed for estimating the anthropogenic influence on rates of record breaking in a given time series is proposed here. The frequency of hot and cold record‐breaking temperature occurrences is shown to be changing due to the anthropogenic influence on the climate. Using ensembles of model simulations with and without human‐induced forcings, it is demonstrated that the effect of climate change on global record‐breaking temperatures can be detected as far back as the 1930s. On local scales, a climate change signal is detected more recently at most locations. The anthropogenic influence on the increased occurrence of hot record‐breaking temperatures is clearer than it is for the decreased occurrence of cold records. The approach proposed here could be applied in rapid attribution studies of record extremes to quantify the influence of climate change on the rate of record breaking in addition to the climate anomaly being studied. This application is demonstrated for the global temperature record of 2016 and the Central England temperature record in 2014.


Current rectification behavior has been proved to be essential in modern electronics. Here, a pseudo-diode is proposed based on protonic/electronic hybrid indium-gallium-zinc oxide electric-double-layer (EDL) transistor. The oxide EDL transistors are fabricated by using phosphorous silicate glass (PSG) based proton conducting electrolyte as gate dielectric. A diode operation mode is established on the transistor, originating from field configurable proton fluxes within the PSG electrolyte. Current rectification ratios have been modulated to values ranged between ∼4 and ∼50 000 with gate electrode biased at voltages ranged between −0.7 V and 0.1 V. Interestingly, the proposed pseudo-diode also exhibits field reconfigurable threshold voltages. When the gate is biased at −0.5 V and 0.3 V, threshold voltages are set to ∼−1.3 V and −0.55 V, respectively. The proposed pseudo-diode may find potential applications in brain-inspired platforms and low-power portable systems.


The Langmuir method for measurement of vapour pressures has been tested for use in studies of decomposition reactions. The isothermal weight loss in vacuum from cleavage (10text-decoration:overline11) planes of calcite (CaCO3) single crystals was measured continuously at temperatures from 934 to 1013 K. The rate was constant until approximately 80% of a 1 mm slice had decomposed. The apparent activation enthalpy was 205 kJ (49 kcal) mol–1. Micrographic examination showed an approximately 30 µm thick layer, probably a metastable form of calcium oxide, separating the calcite from the growing layer of oriented stable calcium oxide. The 30 µm layer yielded a single X-ray diffraction peak which was displaced slightly from the strongest (220) peak of the oriented normal calcium oxide. Lower apparent activation enthalpies measured in previous studies of calcite decomposition in inert atmospheres are suggested to result either from partial diffusion control of the process or from catalysis of the direct formation of normal calcium oxide by carbon dioxide or a component of the system atmosphere. The ratio of the measured decomposition rate in vacuum to the maximum rate, which can be calculated from the Hertz–Knudsen–Langmuir equation, is suggested to be a useful parameter in correlating and predicting decomposition reaction rates.


Diversity indices of double classification (considering the species' assignment and place of catching) were employed for the analyses of Ichneumoninaecommunities of Peucedano-and Leucobryo-Pinetumin three regions of Poland, with four successional stages included. The obtained values of indices allow evaluation of structural changes of Ichneumoninaecommunities of Scots pines crown canopies, in the course of succession and they reveal the regional differences of the process' development. In the climax phase of succession the similar structural pattern of the community for the three regions of Poland was observed. The process of optimal Ichneumoninaecommunity formation is connected with the rise-and-fall succession, with diversity and complexity growing in the earlier stages of the succession and then subject to slow decrease in the later stages. An assessment of 9 indices usability for analysing structural changes in the fauna associations has been completed. Out of them, particularly important for the studying the processes of mature community formation proved two indices: the mean niche width and the mean degree of habitats overlap.


This paper is, with the permission of Stepan Moskaliuk similar to what he will put in the conference proceedings of the summer teaching school and workshop for Ukrainian PhD physics students as given in Bratislava, as of summer 2015. With his permission, this paper will be in part reproduced here for this journal.First of all, we restate a proof of a highly localized special case of a metric tensor uncertainty principle first written up by Unruh. Unruh did not use the Roberson-Walker geometry which we do, and it so happens that the dominant metric tensor we will be examining, is variation in . The metric tensor variations given by , and are negligible, as compared to the variation . Afterwards, what is referred to by Barbour as emergent duration of time is from the Heisenberg Uncertainty principle(HUP) applied to in such a way as to give, in the Planckian space-time regime a nonzero minimum non zero lower ground to a massive graviton, . The lower bound to the massive graviton, is influenced by and kinetic energy which is in the Planckian emergent duration of time as . We find from version of the Heisenberg Uncertainty Principle (HUP), that the quantum value of the Heisenberg Uncertainty Principle (HUP) is likely not recoverable due to . I.e. is consistent with non-curved space, so no longer holds. This even if we take the stress energy tensor approximation where the fluid approximation is used. Our treatment of the inflaton is via Handley et al, where we consider the lower mass limits of the graviton as due to when the inflaton is many times larger than a Potential energy, with a kinetic energy (KE) proportional to , with initial degrees of freedom, and T initial temperature .Leading to non-zero initial entropy as stated in Appendix A. In addition we also examine a Ricci scalar value at the boundary between Pre Planckian to Planckian regime of space-time, setting the magnitude of k as approaching flat space conditions right after the Planck regime. Furthermore, we have an approximation as to initial entropy production. N ~ Finally, this entropy is N, and we get an initial version of the cosmological "constant" as Appendix D which is linked to initial value of a graviton mass. Appendix E, is for the Riemannian- Penrose inequality, which is either a nonzero NLED scale factor or quantum bounce as of LQG. Note that , Appendix F gives conditions so that a pre Planckian kinetic energy( inflaton) value greater than Potential energy occurs, which is foundational to the lower bound to Graviton mass. We will in the future add more structure to this calculation so as to confirm via a precise calculation that the lower bound to the graviton mass, is about 10^-70 grams. Our lower bound is a dimensional approximation so far. We will make it exact. We conclude in this document with Appendix G, which is comparing our Pre Planckian space-time metric Heisenberg Uncertainty Principle with the generalized uncertainty principle in quantum gravity. Our result is different from the one given by Ali, Khali and Vagenas in that our energy fluctuation, is not proportional to that of processes of energy connected to Black hole physics, and we also allow for the possibility of Pre Planckian time. Whereas their result, (and the generalized string theory Heisenberg Uncertainty principle) have a more limited regime of interpolation of final results. We do come up with equivalent bounds to recover and the deviation of fluctuations of energy, but with very specific bounds upon the parameters of Ali, Khali, and Vegenas, but this has to be more fully explored. Finally, we close with a comparison of what this new Metric tensor uncertainty principle presages as far as avoiding the Bicep 2 mistake, and the different theories of gravity, as reviewed in Appendix H


Herein, a multi‐component AlCrTaTiZrRu/(AlCrTaTiZrRu)N0.7 double‐layer structure is prepared by direct current (DC) magnetron sputtering as a diffusion barrier for Cu interconnection. To verify the diffusion‐barrier properties at high temperatures, the Cu/AlCrTaTiZrRu/(AlCrTaTiZrRu)N0.7/Si structures are annealed at 700–900 °C for 30 min in high vacuum. The barrier layer remains amorphous with few nanocrystalline structures after annealing at 800 °C. Cu particle agglomeration begins to appear on the surface, but no Cu‐silicide compound is found on the Si substrate, indicating that the layer can effectively defer the interdiffusion of Cu and Si. Under annealing at high temperature of 900 °C, Cu silicides and other intermetallic compounds are formed on the surface of the Cu film, with the film resistivity increasing significantly, indicating that the AlCrTaTiZrRu/(AlCrTaTiZrRu)N0.7 double‐layer structures have completely failed.


As the main agricultural area of Shaanxi Province, the Guanzhong Basin has a fragile ecology and frequent droughts. This study focuses on the intensity, duration, and frequency of meteorological droughts in Guanzhong Basin, from 1955 to 2015, and the temporal-spatial characteristics of meteorological drought were evaluated based on the standardized precipitation evapotranspiration index (SPEI). Our results show that the four SPEI values all show a decreasing trend with time, which indicates that the frequency of droughts is gradually increasing. Moreover, the frequency of meteorological droughts does not exceed 40%, with a decreasing order of light drought > moderate drought > heavy drought > extreme drought. The mild drought, moderate drought, severe drought, and extreme drought mainly occur in the eastern, west, south, and north parts of the Guanzhong Basin, respectively.


The family Paenibacillaceae has been created on the basis of the analysis of 16S rRNA gene sequences. It embraces the speciesrich type genera Paenibacillus, Ammoniphilus, Aneurinibacillus, Brevibacillus, Cohnella, Oxalophagus, and Thermobacillus and the recently described genera Fontibacillus and Saccharibacillus. Oval to ellipsoid spores are formed, most species are Gram staining positive, and some stain Gram negative. Other characteristics of taxonomic values are varying such as motility, relationship to oxygen, and catalase formation. The major menaquinone is either MK-7 or MK-6; anteiso-C15:0, iso-C15:0, iso-C16:0, and C16:0 are the major fatty acids; and the mol% G+C ranges between 36 and 59. Members of the family are frequently isolated from various soil habitats, compost, and various plant materials but also from freshwater, blood, and feces. The biology of the genus Cohnella is described here in greater detail.


An optical sensor and a deformation detection system in which the optical sensor is used. The optical sensor includes an optical fiber, an elongated hollow housing having an interior portion, and a material disposed on an inner surface of the housing that produces a persistent change in an optical signal transmission property of the optical fiber when the optical fiber contacts the material. The optical fiber elastically extends between opposing ends of the housing such that a bending deformation of the housing beyond a threshold radius of curvature causes a contact to occur between the material and the optical fiber. The contact results in persistent change in the optical signal transmission property of the optical fiber, which can be detected to determine whether deformation of the device occurred beyond a predetermined threshold value. The deformation detection system can use one or more of the optical sensors attached to the device.

The aim of our study was to establish the effects of carbonated drinks and fruits drinks on the onset and the level of dental erosions on the central incisors and the first permanent molars.
In order to objectify the existence of dental erosion among the population, research was made in different urban environments in the city of Shtip and its surrounding. The total sample consisted of 31 respondents (17 male and 14 female) with positive signs of dental erosion. In the methodology we used specially constructed questionnaires in which we input the data about the consumption of carbonated and fruits drinks and from a clinical standpoint we input data about the depth of the dental erosions according to teeth and surfaces.
The monitoring of the distribution of dental erosions that were diagnosed on the central incisors and the first permanent molars, in correlation to the gender of the examinees, did not show a significant difference (p>0.05). The results we got for the existence of dental erosions according to surfaces of the examined teeth, in correlation to the gender of the examinees, did not show a significant difference (p>0.05). The correlation between the use of carbonated drinks and dental erosions on the central incisors was with a medium strong negative insignificant correlation p>0.05. The data which represents the association of dental erosions, according to tooth surface, and the consumption of carbonated drinks during the whole week and of fruit drinks during the whole day,on the central incisors, showed, that there is no statistically significant difference p>0.05. In the examined correlation between the consumption of carbonated drinks and dental erosions of the first permanent molar, we can see that there is a medium strong negative significant correlation p 0.05). The correlation between the use of fruit drinks and dental erosions of the first permanent molar was with a medium strong negative significant correlation p<0,05, where the increase of the use of fruit drinks is followed by a decrease in the level of erosive changes. We can conclude that it is necessary to carry out a study, that would include the most influential etiological factors, which would help in the preparation of preventive strategies.


This paper addresses the problem of establishing upper bounds of the L2 gain of 2D mixed continuous-discrete-time systems. A novel linear matrix inequality condition is proposed based on the introduction of a complex linear fractional representation of the systems and on the use of complex Lyapunov functions depending rationally on a parameter. As shown by an illustrative example, the computational burden of the proposed condition may be rather smaller than existing conditions.

However, considering many traditional marketing practices, it is not difficult to see how this fundamental truth has been obscured. Too often pricing is used as a tactical lever that is pushed or pulled as needed to respond to competitors' actions. Price promotions are often used to gain short-term volume that has little positive impact over the long term. Ruthless price competition can destroy prodigious amounts of brand value. While consumers may enjoy the reduced prices that result from these actions, they may not be getting a bargain in the long term if brands are unable to invest in innovation or, worse, if they go out of business, leaving consumers bereft of choice.
