Heat treatment is the most popular processing technique in the dairy industry. Its main purpose is to destroy the pathogenic and spoilage bacteria in order to ensure that the milk is safe throughout its shelf life. The protease and lipase that are present in raw milk might reduce the quality of milk. Plasmin and protease, which are produced by psychrotrophic bacteria, are recognized as the main causes of the deterioration in milk flavor and taste during storage. The enzymes in raw milk can be inactivated by heat treatment. However, the temperature of inactivation varies according to the type of enzyme. For example, some Pseudomonas spp. produce heat-resistant proteolytic and lipolytic enzymes that may not be fully inactivated by the low temperature and long time (LTLT) treatment. These types of enzymes are inhibited only by the high temperature and short time (HTST) or ultra-high temperature (UHT) treatment of milk.


The relocation of the earthquake hypocentre is necessary in order to determine the position of the earthquake centre with higher accuracy. An accurate hypocentre position is important for earthquake-prone areas mapping, seismicity analysis, and fault zone identification. The double difference algorithm technique using the hypoDD program can be used for hypocentre relocation. This article reports the earthquake relocation of 23 earthquakes in the Yogyakarta region recorded at four observation stations. The result shows that the hypocentre shift spreads randomly with a shift distance of less than 20 km, with the most shifting direction of the epicentre to the northeast. The Earthquake's hypocentre after relocation in the land area is estimated to be triggered by a fault under the Gamping Wungkal Formation, while the earthquake around Mount Merapi is estimated to be triggered by volcanic activity. The Relocation result in the sea area show that the hypocentre leads to the subduction line.

ABSTRACT Scholars, educators, writers, and librarians have been calling for richer literary depictions of Black culture since the 1930s. Using a critical content analysis framework with the books Ada Twist, Scientist and Crown: An Ode to the Fresh Cut, I discuss how the concepts of fugitivity, fantasy, futurity, and freedom relate to contemporary depictions of Blackness in children's literature. Nearly a century after the movement for more diversity in children's literature began, we exist in an era when Black stories are imbued with dreams about an equitable future. In Ada Twist, Scientist, a little Black girl with boundless scientific curiosity defies limitations placed on her ability to inquire and discover. In Crown: An Ode to the Fresh Cut, a barbershop serves as the backdrop for a little Black boy's loving poem to his people. Using the aforementioned scholarly and literary works as a point of departure, I take the following questions to task: Why is children's literature with rich depictions of Black culture beneficial for Black children, their teachers, and their classmates? How can educators of Black children look for themes of fugitivity, fantasy, futurity, and freedom to critically analyze children's literature, and why is it important to do so?


This paper uses the data of 1338 rural households in the Northern Mountainous Region of Vietnam to examine the extent to which subsidised credit targets the poor and its impacts. Principal Component Analysis and Propensity Score Matching were used to evaluate the depth of outreach and the income impact of credit. To address the problem of model uncertainty, the approach of Bayesian Model Average applied to the probit model was used. Results showed that subsidised credit successfully targetedthe poor householdswith 24.10% and 69.20% of clients falling into the poorestgroupand the three bottomgroupsrespectively. Moreover,those who receivedsubsidised credit make up 83% of ethnic minority households. These results indicate that governmentalsubsidies are necessary to reach the poor and low income households, who need capital but are normally bypassed by commercial banks. Analyses also showed that ethnicity and age of householdheads, number of helpers, savings, as well as how affected households are by shocks were all factors that further explained the probability at which subsidised credit has been assessed. Furthermore, recipients obtained a 2.61% higher total income and a 5.93% higher farm income compared to non-recipients. However, these small magnitudes of effects are statistically insignificant at a 5% level. Although the subsidised credit is insufficient to significantly improve the income of the poor households, it possibly prevents these households of becoming even poorer.


We present a structural analysis of NGC 891, an edge-on galaxy that has long been considered to be an analogue of the Milky Way. Using star-counts derived from deep Hubble Space Telescope/Advanced Camera for Surveys (HST/ACS) images, we detect the presence of a thick disc component in this galaxy with vertical scaleheight h z = 1.44 ± 0.03 kpc and radial scalelength h R = 4.8 ± 0.1 kpc, only slightly longer than that of the thin disc. A stellar spheroid with a de Vaucouleurs-like profile is detected from a radial distance of r ∼ 0.5 kpc to the edge of the survey at r ∼ 25 kpc; the structure appears to become more flattened with distance, reaching q = 0.50 in the outermost halo region probed. The halo inside of r ∼ 15 kpc is moderately metal-rich (median [Fe/H] ∼ -1.1) and approximately uniform in median metallicity. Beyond that distance, a modest chemical gradient is detected, with the median reaching [Fe/H] ∼ -1.3 at r ∼ 20 kpc. We find evidence for subtle, but very significant, small-scale variations in the median colour and density over the halo survey area. We argue that the colour variations are unlikely to be due to internal extinction or foreground extinction, and reflect instead variations in the stellar metallicity. Their presence suggests a startling conclusion: that the halo of this galaxy is composed of a large number of incompletely mixed sub-populations, testifying to its origin in a deluge of small accretions.

To the Editor Nursing homes are required to provide personal care to a broad range of residential patients. While medications are an integral part of this care, medication risks may not recognised, particularly in vulnerable elderly patients. Pharmacist-led medication reconciliation has been shown to reduce the number of medications in nursing homes, and is part of USA health care (1–3). In Malaysia, few studies have examined this issue. We conducted a prospective exploratory study which involved medication review of 20 residents of a nursing home in a semi-urban setting, from 1 November 2013 to 31 January 2014. Medication review was undertaken by a year 4 pharmacy student with input from a clinical pharmacist, who together took a medical history, recorded details of all medication, and current medical problems. Medication-related problems were identified from this data. Potentially inappropriate medications with clear causal correlations or contribution to the principal reason were documented. Another clinical pharmacist independently classified each medicationrelated problem. Disagreement was resolved through discussion to arrive at a consensus classification. The Monash University Human Research Ethics Committee approved this study (CF13/2911-2013001564). The mean age of the 20 study subjects was 64 years (range 48–85). The total number of prescribed medications was 96 (mean: 4.8; median: 5; range: 1–12). Fifteen subjects had two or more documented comorbidities, including hypertension, diabetes and schizophrenia. We identified 122 medicationrelated problems in the 20 individuals, a mean of 6.1 problems per individual. The most common problems were drug–drug interactions, identified in the medications of 11 individuals (Table 1). Most of these interactions related to the use of antihypertensive agents and longterm use of non-steroidal anti-inflammatory drugs (NSAIDs). Two other significant issues were (i) a high prevalence of untreated indications and (ii) the number of seemingly inappropriate prescribing decisions. For example, seven individuals complained of nocturia which was had not been identified or treated. Similarly, another seven individuals were prescribed anticholinergic agents to treat the extrapyramidal effects of neuroleptics. Medication-related problems have important implications for morbidity, hospitalisation rates and quality of life (4). This exploratory study suggests that pharmacist-led medication review is of significant benefit for improving medication safety in a nursing home for older adults, many of whom have comorbidities and are on multiple medications. Clinical pharmacists' are well suited for this role due to their training (5) in pharmacotherapeutics, which enables them to identify medication-related problems. One significant example is the identification of prolonged, inappropriate NSAID use, which carries significant dose-related cardiovascular, renal and hematological risk (6). With regular medication review, this can help identify adverse events and ensures that NSAIDs are discontinued when no longer indicated. Indeed, this study suggests that pharmacist-led medication review can be a simple and low-cost intervention. It has the potential to significantly enhance medication safety in a vulnerable section of the elderly population. Medication review should be part of the routine collaborative care of such patients, and should involve physicians, nursing home carers and pharmacists.


Tennessee Williams is one of the most highly recognized and prolificAmerican dramatists of the twentieth century. Critics such as Roger Boxill, Lyle Leverich, and Donald Spoto maintain that Williams presents cases for the alienated, the dysfunctional, and other outcasts of society, and that his genius sparks concern for their suffering, which may account for his plays' enduring popularity. Williams' first three major plays The GlassMenagerie (1945), A Streetcar Named Desire (1947), and Summer and Smoke (1948); present the plight of sensitive, helpless women who are victims in Southern patriarchal society, either degraded or destroyed in their search for identity and security. Through these plays, Williams makes a critical plea for society to address the predicament of marginalized women in a cruel and insensitive world. This paper details, The GlassMenagerie as a representation of marginalised women and literature as a vehicle to make public awareness on patriarchy.


Stomata are microscopic pores that are critical for plant survival by regulating plant gas exchange and water regulation. They do this by moderating the aperture of the pore through the two flanking guard cells, which change shape in response to large changes in internal turgor pressure. The extent to which guard cells change shape is dependent on the anisotropic growth and deformation of the guard cell wall, and it is this shape change that is fundamental to the opening and closing of the stomata. Modellers of guard cell mechanics and function are increasingly realising that guard cell shape is crucial for understanding how guard cells can function under such conditions, yet there has been little detailed characterisation of guard cell shape change.

In this thesis, I present a novel method of imaging Arabidopsis guard cells using confocal microscopy and a way of processing these images to create 3D reconstructions of the guard cells. These reconstructions provide novel quantitative data on guard cell volume, surface area and other geometric parameters when the stomata are both open and closed. These data provide a novel insight into the type of shape changes that guard cells undergo to control pore aperture. I then report on a series of genes implicated in the control of guard cell shape, focussing on a subunit of the ARP2/3 complex, and a family of proteins implicated in regulating cell wall extensibility, the expansins. By a combination of mutant analysis and stomatal functional bioassays, as well as thermal imaging and gas exchange analysis, I provide evidence for a role of the ARP2/3 complex and expansins in guard cell function.


This paper presents space vector PWM algorithm for six- switch three-phase inverters (SSTPI) using Artificial Neural Networks (ANN) based on the ready-to-use field-programmable gate array (FPGA) technology. ANN is used to calculate ON-OFF time for six switches when given the angle and modulation index of required voltage space vector. This approach has the advantage of very fast implementation of an Space Vector PWM (SVPWM) algorithm that can increase the converter switching frequency, particularly when the field-programmable-gate-array (FPGA) technology is used in the modulator. This SVPWM is also validated experimentally using FPGA-XUP VIRTEX II PRO from Xilinx in SSTPI-IM system for under modulation mode and over modulation mode 1 and 2, extended to six-step mode, especially for 40khz-switching-frequency case.


Correspondence XintingGe,University of SouthernCalifornia, LosAngeles,CA,USA. Email: firstname.lastname@example.com Abstract Background: Tau tangles and amyloid plaques are specific biomarkers that define dementia of Alzheimer's disease (AD). However, behavioral changes or neuropsychiatric symptoms (NPS) are the natural course of AD, which impact the patients' quality of life and caregivers' burdens. Relationship between tau tangles or changes of cortical thickness and 'noncognitive' symptoms such as behavioral changeswere understudied. Method:497 subjectswere selected fromAlzheimer'sDiseaseNeuroimaging Initiative (ADNI) project. Participants underwent tau positron emission tomographic (PET) scanningwith 18FAV-1451, AβPET scanningwith florbetapir or florbetaben,magnetic resonance imaging, and cognitive and behavioral testing. A 4-group division approachwas proposed using both amyloid (A-/A+) and behavior (B-/B+) status: A-B-, A-B+, A+Band A+B+. Multivariable linear regression model was used to delineate the relationship of tauopathy/neurodegeneration and cognitive decline for each group. Result: The tau deposition increased significantly from the Agroup to the A+ group, and the associated regions spread into nearly the whole brain. No correlations of the cortical thickness with cognitive decline were found for both the Aand A+ groups. Considering the behavior status, no associations were found for both the A-Bgroup and the A+Bgroup. The association of cognitive decline with tau deposition was observed in the temporal lobe (entorhinal cortex, para-hippocampal gyrus, et., al) for the A-B+ group and spread into nearly the whole cerebrum for the A+B+ group. For cortical thickness, the associations with cognitive decline show similar spreading patterns of tau deposition for the A-B+ groupwhile nearly no difference of the associated regions for the A+B+ group. Conclusion: The association of cognitive decline with tauopathy/neurodegeneration were driven by the subjects with abnormal behavior status (B+ groups), while there were nearly no associations for Bgroups (Aand A+). NPS may have the ability to improve the differentiation sensitivity of Aβ on the severity of tauopathy/neurodegeneration. Several factors such as tau tangles, amyloid plaques, cortical atrophy, and behavior symptoms should be considered together for neuropsychiatric disorder diagnosis.


A commercial b-hemolytic Streptococcus vaccine for Japanese flounder was examined for the protective eficacy against Streptococcus iniae infection of threadsail filefish Stephanolepis cirhifer. In the artificial infection test a high mortality rate (90%) was obtained by intramuscular inoculation with S. iniae as low as 10 CFU/100 g body weight. In the vaccination test intraperitoneal inoculation with the vaccine at the usual and 1/10 dosages resulted in a high protective efect (RPS≧ 85%), and the high protective eficacy was kept for at least 7 months.


Polymer drugs are those in which a polymer agent has a direct therapeutic effect on the body. A major investigated area of polymer drugs is their use as binding agents, or sequestrants, which can neutralize or remove undesired components from the body. By taking advantage of the unique properties of crosslinked, insoluble polymers, new polymer drugs continue to be developed for oral use, acting in the gastrointestinal tract and excreted in the feces. Soluble polymer binders may be administered by a variety of routes and act at diverse sites of therapeutic action. This article reviews the properties of polymer drugs, particularly sequestrants, with an emphasis on recent advances in polymer properties which may enhance the utility of this class of drugs. © 2017 Wiley Periodicals, Inc.

ABSTRACT Using Turkish firm-level data for the period 2003–2010, we look at the relationship between foreign direct investment, absorptive capacity, and spillovers at a disaggregated level, and analyze whether firms operating in different quantiles of the productivity distribution respond differently to foreign presence and changes in absorptive capacity. The results reveal that, for a given level of foreign presence, it pays to increase the absorptive capacity of firms operating in lower quantiles. When it comes to inter-industry spillovers, it is counterproductive to increase the absorptive capacity of firms already operating in higher quantiles, as this diverts resources from other productive activities.


The volume of N2O absorbed by the lung can be measured during inspiration before the gas is taken up in significant amounts by the capillary blood flow by a plethysmographic technique. If the alveolar fraction of N2O and its solubility coefficient are known, the combined pulmonary tissue and capillary blood volume (Vt+c) can be calculated. Vt+c averaged 517 ml, sd 61 ml, in nine adult males, values in good agreement with those obtained by other methods. The pulmonary tissue volume alone, Vt, in six of these subjects was 438 ml, sd 58 ml. A modification of the technique, using CO2 as the test gas, permitted calculation of the CO2 dissociation slope of the lung tissue. In five subjects, the CO2 dissociation slope of the lung, without the buffering effect of pulmonary capillary blood, over a range of PaCOCO2 from 31 to 55 mm Hg, averaged 0.30 ml CO2 STPD/100 ml lung tissue per mm Hg, or including physically dissolved CO2, 0.38 ml CO2 STPD/100 ml lung tissue per mm Hg. Because Vt is about four times larger th...

ABSTRACT The immunoglobulin G (IgG) antibody is important for detecting and evaluating immune responses. Despite increasing opportunities for tigers to be exposed to emerging diseases due to global changes coupled with increasing interaction with humans, there is no available antibody specific to tigers. Aims of this study were to produce a rabbit anti-Bengal tiger (Panthera tigris tigris) IgG polyclonal antibody and to determine its specificity. The molecular weight of the purified Bengal tiger IgG was approximately 170 kDa. The cross-reactivity of rabbit anti-Bengal tiger IgG to IgG of other wild felid species and other domestic animals was analyzed by indirect enzyme-linked immunosorbent assay. The cross reactivity to other related wild animals ranged from 53.69% to 75.63%. There was high cross-reactivity with domestic cats (63.58%) and pigs (38.45%) and low cross-reactivity with domestic cows (10.46%), goats (8.60%), sheep (7.25%), and chickens (6.91%). To confirm cross-reactivity with domestic animals' IgG, western blotting was performed. These results indicated that the purified rabbit anti-Bengal tiger IgG polyclonal antibody strongly reacted with species in the family Felidae. The polyclonal antibody generated in this study has the potential to aid in the development of useful tools for further novel immunological investigations on tigers and related felid species.


High-speed wireless computing networks are now economically feasible for home users, via 802.11b wireless protocols and their associated hardware. Such centralized "point-to-multipoint" installations typically allow a range of about 100 meters from the central access point. It is possible to use the same network protocols and hardware to construct a "wireless mesh" or "multipoint-to-multipoint" network in which any connected node can communicate directly or indirectly with any other connected node. The research project described in this article applies wireless mesh networking to inter-vehicular communication. Three vehicles were connected as a wireless mesh network using laptop computers with 802.11b radio cards and mesh networking software. The vehicles were then driven on a highway in Northern California to collect data about network connectivity. The goal of the experiment was to prove that such a network could be quickly and easily constructed and that network connectivity could be maintained under normal driving conditions. Data was collected on network connectivity and time delay of network packet transmission.


We give two different approaches to classifying the simple modules of $0$-Yokonuma-Hecke algebras $Y_{r,n}(0)$ over an algebraically closed field of characteristic $p$ such that $p$ does not divide $r.$ Using the isomorphism between the $0$-Yokonuma-Hecke algebra and $0$-Ariki-Koike-Shoji algebra, we in fact give another way to obtain the simple modules of the latter, which was previously studied by Hivert, Novelli and Thibon (Adv. Math. $\bf{205}$ (2006) 504-548). In the appendix, we give the classification of simple modules of the nil Yokonuma-Hecke algebra.


In this paper, we compare welfare effects and the extent of sectoral adjustments of the member countries under alternative free trade agreement (FTA) sequencings in the Asia-Pacific region using a dynamic computable general equilibrium (CGE) model. If a Trans-Pacific Partnership (TPP) agreement under one sequencing and an East Asian FTA (EAFTA) under another sequencing will enter into force at the same time, followed by more enlarged FTAs, then a larger number of countries are expected to realize greater welfare gains under the Asia-track sequencing. However, given the uncertainty about the establishment of an Asia-wide FTA in the near future, the TPP-track sequencing appears to be an attractive option for most countries in the Asia-Pacific region. With respect to sectoral adjustments, there seem to be no significant differences among the alternative sequencings considered in this study.


We develop a theory for the current-direction dependence of the normal-zone propagation velocity observed in multifilamentary composite superconductors. Normal-zone propagation is known to be driven primarily by Joule heating in both the normal zone and the current-sharing zone, which lies between the normal (T>T c ) and superconducting (I c ) zones. We show, however, that the Peltier effect is an important secondary source of heating and cooling in the current-sharing zone and accounts for essentially all of the current-direction dependence of the normal-zone propagation velocity observed in a Nb 3 Sn/Cu composite conductor. For one current direction Peltier heat is deposited in the current-sharing zone, thereby adding to the Joule heat and increasing the normal-zone propagation velocity, while for the other current direction Peltier heat is absorbed, thereby cooling the current-sharing zone and thus decreasing the normal-zone propagation velocity. Contrary to the claim of Gurevich and Mints, we find that the Thomson effect is about an order of magnitude too small to account for the current-direction dependence observed in a Nb 3 Sn/Cu composite conductor.


In 1982, the AACSB liberalized the standards by which a faculty member can be judged as "terminally qualified" for purposes of AACSB accreditation. In specific, doctorates from non-business disciplines can gain "terminal status" if they demonstrate that they have mastered a busines discipline and are contributing to it. Deans, however, are often confused about what constitutes a legitimate transition and how the AACSB will probably evaluate a specific faculty member. This paper will explore the AACSB's criteria for evaluating outside Ph.D.'s so that Deans can make informed decisions when hiring outside Ph.D.'s and so that Deans can counsel these faculty to insure they will eventually earn terminal degree status.


Suzi notation records ancient Chinese music and,it is therefore,has special meaning in musicological study.According to the message left by Mr.Yang Yinliu,the authors discovered the Suzi notes of the Short lyric of Cudrania Twig(柘枝令)and the Vocal Introduction to the Short Lyric of Cudrania Twig(柘枝令歌头)from a Song(宋朝)book the notes from a Hermit of Mt.Mao(NFDA4峰真隐漫录)written by Shi Hao(史浩)and dating back to 1181 AD.Except tracing the book to different historical versions and estimating the value of finding the style of the Suzi notes,the possibility of conveying the notation into modern form,the modal system of the music and the way of performing the piece are also esplored in this article.


ABSTRACT This paper describes the responses of two different classes to small group-based instruction. A remedial algebra class, despite achievement gains, expressed displeasure and frustration in the small group format. An Elementary Education Mathematics Content course showed great enthusiasm and success to the instructional approach. Explanations are presented for the differences in the learning behaviors, including individual differences and changes in the overall instructional approach.


In this paper, a TSN test scheme of real-time edge computing platform framework is proposed, and a specific TSN test platform is built. By using the open structure of real-time edge computing platform, we can install the communication devices based on time-sensitive network. We can collect and supervise the status of TSN real-time communication flow with the help of the real-time data engine with timing database as its core. Based on the test, this paper has built a testing platform and carried out the performance test of clock synchronization and end-to-end delay.


Microorganisms are everywhere. They can be found in the air, in water, in soil, on animals and even on humans. Some are beneficial, such as those used to make fermented dairy and meat products. Others cause spoilage of various food products. Eating fruits is a healthy practice due to its nutritional composition but when it gets spoiled by microbes, it can be harmful for human consumption. Microorganisms have been reported to cause extensive deterioration of fruits. Some of these microorganisms cause rotting, discoloration or fermentation of the fruits which affect their preservation. The study was done to identify and analyse  microbial diversity that causes the spoilage. Pour plate method was used for the isolation of microbes from spoil fruit. A portion of the fruit was aseptically inoculated into the beaker; it was homogenized and then diluted. The colonies were identified by standard bacteriological procedures. Gram's staining was performed to determine if the organism is gram negative or gram positive. Further confirmatory biochemical tests were done such as catalase, coagulase and oxidase. The identification of the isolated fungi was done both macroscopically and microscopically. This study and experiments revealed that the rotten or spoiled fruit possess appreciable number of microbes. The Microorganisms isolated and observed were bacteria and fungi majorly. This is due to various processes taking place in the rotten fruit which favoured bacterial and fungal growth. It could also be as a result of the moisture content of the fruit as well as the difference in the nutritional composition of the fruits. This work finds that there are microorganisms that could be responsible for inducing spoilage in the fresh fruit. Fruits are a good source of nutrient and could be used for many applications. However to reduce the susceptibility of the fruit to microbial spoilage and to ensure its effectiveness in different applications and safety measures should be taken. Hence if you want to prevent spoilage of food by micro-organisms, you must remove the conditions which are appropriate for their growth and preserve them with the best possible techniques.


Marzanski et al ( Psychiatric Bulletin , September 2006, 30 , 327–329) highlight the shortcomings of the Hippocratic Oath in their survey of psychiatrists' attitudes. The Oath has become flawed for two main reasons.

First, it is outdated. It contains archaic, gender-specific language but, more


Histomonas meleagridis (H. meleagridis) is a protozoan parasite that may cause histomoniasis, a disease of special importance to the poultry industry and public health. The molecular characterization of H. meleagridis in China has not been established. The 5.8S and flanking ITS regions were amplified by polymerase chain reaction from 15 liver samples of chickens which were preliminarily diagnosed with H. meleagridis infection by observing clinical symptoms and macroscopic changes in the organs in Eastern China between 2012 and 2013. The obtained sequences were aligned and compared with other known sequences of H. meleagridis and related protozoan species based on ITS1-5.8S rRNA-ITS2 or 5.8S rRNA region alone. Out of the 15 obtained sequences, 8 sequences were identified as H. meleagridis and were grouped into five clades, suggesting the possibility of multiple genotypes within the samples. Among the remaining 7 sequences, 4 sequences were more related to Trichomonas and 3 sequences were more related to Tetratrichomonas, which suggests the possibility of misdiagnosis or coinfection with other protozoans. Therefore, there is obvious genetic diversity of H. meleagridis based on the 5.8S and flanking ITS regions, which suggests the presence of different genotypes in chickens from Eastern China.


We present theoretical estimations of the electrical conductivity of a warm expanded aluminium plasma (ρ = 0.3 g cm−3). Our calculations are carried out in the framework of density functional theory and the local density approximation. Ionic configurations were determined by ab initio molecular dynamics simulations, from which the conductivity was computed using the Kubo–Greenwood formula. Theoretical results were validated in the dense coupled regime (ρ = 2 g cm−3) against previously published experimental results. For the low-density regime, the result is compared to experiments obtained in our laboratory in an isochoric closed-vessel designed to confine electrical plasma discharges up to 1.5 GPa. In this regime we show that the usual Drude model is no longer relevant and that the electrical conductivity is driven by the optical properties.

reason for the above observations.


During optimally evaluating a design plan of gas-transmission pipeline,the effect of index weight on evaluation result should be taken into consideration because different indexes have different importance.However,in an actual calculation,the plan is evaluated by a definite weighted value based on the importance,and uncertainty of weighted value is not concerned.In this paper,the index weight with uncertainty is showed in a form of interval number in order to improve accuracy and credibility of plan.Meanwhile,an interval numerical model to optimally evaluate this plan is established.In addition,this model has been testified by some cases.


In this paper, ice shelf movements caused by ocean tides are measured by Interferometric synthetic aperture radar (InSAR) and an tidal constituent of an ice tongue in West Antarctica is estimated using ERS-1/2 tandem mission differential InSAR (DInSAR) observations. We assume that InSAR observed ocean tidal heights can be derived after correcting the InSAR data for the effect of atmospheric loading using the inverse barometric effect, solid earth tides, and ocean tide loading. Here, the dominant tidal constituent O1 underneath the Sulzberger ice shelf is estimated using 8 differential interferograms. The resulting tidal constituent is compared with a contemporary regional tide model (CATS2008a) and a global tide model (TPXO7.1). The InSAR estimated tidal amplitude agrees with both models with root-mean-square (RMS) differences of < 2.2 cm and the phase estimate corroborating both tide models to within 8˚. We conclude that fine spatial scale (∼200 m) Antarctic ice shelf ocean tide determination is feasible for dominant constituents using C-band ERS-1/2 tandem mission InSAR.


The usefulness of sonognaphy for guidance of percutaneous aspiration biopsies of solid masses on fluid collections is well established [1-6]. Visualization of the needle tip can, however, be difficult at times, especially if a narrow angle technique is used on the needle is inserted parallel to the ultrasound beam. We describe the use of color Doppler flow imaging for enhancement of needle tip and shaft visualization and its application during aspiration biopsies.


Women as bearers and nurturers of children provide the foundation for generating future citizens for the country and labourers for the economy. In addition to reproductive or care work, women also contribute as workers to the nation's gross national product. In the labour market, women's reproductive role constrains their full participation and also acts as a basis of gender discrimination. Maternity Benefit is a tool that mainly enables women to participate in the labour force even while pregnant and provides employment protection and compensation for loss of wages while on maternity leave. In India, poverty and vulnerability provide additional arguments for state provision of social security including maternity protection and childcare. The Indian state is bound to the provision of Maternity Benefit not only by the Constitution but also by being a signatory of the ILO Convention 1919. This report on women's work, maternity protection and policy in India aims to provide a critical overview and assessment of the adequacy and efficacy of existing arrangements for Maternity Benefit in India; to highlight the knowledge gaps, lessons and best practices; and give recommendations for legislative and operational improvement


The emerging awareness on sustainability issues among Malaysian listed companies has increased the voluntary disclosure on environmental, social and governance (ESG) in the annual report. This study examines the relationship of board diversity on firm's sustainability practices. Board diversity characteristics in terms of gender, age, board composition, board capabilities and board reputation are examined as to their influence towards firm's sustainability practice. The data includes the ESG Scores of 38 listed companies in Malaysia for the period in 2010–2016 which was obtained from the Thomson Reuters Eikon™ Datastream. The result showed that board diversity traits such as age, board capabilities and board reputation are positively associated with firm's sustainability practices. In contrast, women director and independent directors are negatively related with firm sustainability practice. Result of this study helps to provide another viewpoint on the roles played by board members, particularly their diversity representations as the determinant for corporate sustainability practice.


Abstract This paper discusses spatial sound movement in Xenakis's music from Pithoprakta (1955–56) to Alax (1985). Evolution of stochastic sound masses in Pithoprakta is linked to a rudimentary form of motion of sound on the stage. Eonta (1963–64) explores performer movement and the directional quality of brass instruments (e.g., change of timbre through axial rotations of the players). In Terretektorh (1965–66), for orchestra scattered among the audience, apparent sound motion is constructed by means of Archimedean, logarithmic and hyperbolical spirals. The climax of Persephassa (1969) consists of several superimposed layers of sound, rotating simultaneously in different directions. Alax (1985) for three identical ensembles, presents spatial canons, sound planes, etc. Xenakis's original use of spatial sound movement in music juxtaposes technical sophistication with an overwhelming forcefulness of expression.


This study was designed to determine a word problem difficulty classification in children with arithmetic learning disabilities (ALD; n = 104) in comparison with typically achieving students (n = 44). We tested variables such as (a) semantic structure (Change, Combine, Compare, and Equalize), (b) operation (subtraction and addition), and (c) position of the unknown quantity in the problem. Facet theory with multidimensional scaling techniques (MINISSA) was used to analyze the underlying dimensions in the responses of each group of participants. Our results indicate that although the word problem difficulty classifications for the 2 groups of children were different, the position of the unknown quantity had a greater influence on the level of difficulty of story problems than other variables. The noncanonical problems—specifically, those with the unknown term in the first place—although difficult for both groups of children, were the most difficult problems for children with ALD.


Let R and A be commutative rings with identity, and m and n be integers ≥3. Consider when and how an isomorphism E_m(R)E_n(A) can be lifted to an isomorphism between the corresponding Steinberg groups. It was proved that, if E_m(R) is isomorphic to E_n(A) then m=n (cf. Ref. [1]). When n≥4, every isomorphism E_n(R)E_n(A) is of the standard type, and it can be naturally and uniquely lifted to an isomorphism from St_n(R) to St_n(A) (cf. Refs. [1] and [2]). However, the case n=3 is different from that n≥4, since


Thank you for the clipping you sent me containing Mr. Ward's review (Journal qfGlaciology, Vo!. 3, No. 22, 1958, p . 146) of my first article on the crevasse detector. This review is correct in all essential respects and brings the subject approximately up to date. I am enclosing for your retention a copy of the latest publication (The design of a crevasse detector for polar exploration. Journal of the Franklin Institute, V o!. 264, No. 5, 1957, p. 361-77).* It is proposed that future development will take the form of simplification. We may have a third publication containing final test results in about two years. I was in New Zealand returning from a short sojourn in the Antarctic when the news of Dr. Fuchs's successful r eturn was published. Apparently he did not use crevasse detectors, yet he and Hillary were fairly successful in getting through by purely "mechanical cxploration". On the other hand, Albert Crary used a crevasse d e tector throughout his 1400 mile (2250 km.) traverse of the Ross Ice Shelf, and told me he considered it indispensable. It remains to be seen what the best compromise will be between the two extremes.


In this study, red, green, and blue light-emitting diodes (LED) are adopted as the light source to illuminate sequentially a two-dimensional soap film channel flow. Triple-exposure particle image is recorded on the same image frame by a 3-ccd color camera. Since the particles illuminated by the R, G, B LED will only be recorded on the R, G, B ccd-chip of the digital camera, three sequential exposure, R, G, B particle images can be obtained from separating the triple-exposure particle image. Two sequential velocity fields can be determined from the correlation analysis of the R-G and G-B sequential particle images. Time derivative of the velocity fields, and hence the evolution of the unsteady flow or the characteristics of turbulent flows can be analyzed from the two velocity fields determined. The color PIV method incorporated with the LED light has proven to be a cheap, safe, and powerful tool for the full-field flow measurements. Results of the flow past circular cylinder in the confined soap film channel flow are presented.Copyright © 2006 by ASME


This case report showed an AOT in a 12-year-old female patient referred for orthodontic-surgical of both impacted right mandibular canine and lateral incisor. Cone beam computed tomography revealed a well-defined mixed hyperdense/hypodense lesion, involving the crown of the mandibular lateral incisor. The surgery consisted in surgical exposure of the mandibular right canine and lateral incisor, bonding of the lateral incisor for orthodontic traction and curettage of the mandibular lesion. Histopathological examination revealed several columnar epithelial cells with minimal stromal connective tissue, lobular pattern and rosettes and duct-like structures, confirming the diagnosis of AOT. After, the patient was referred for orthodontic traction of the impacted teeth. At 1 and 3-year postoperatively, follow-ups examinations showed extensive bone repair, resolution of the tooth-retention and absence of recurrence. Although AOT is an uncommon lesion in the mandible, it should be considered in the differential diagnosis of the mixed profile lesions in this region.

Background: Mobile Personal Health Records (mPHRs) are mobile applications that allow organizing and saving the patients' health data in order to ease their management and access for both patients and doctors. Objective: This study aims to evaluate, based on ISO/IEC 25010 quality standard, the software quality of mPHRs for pregnancy monitoring. Method: An External quality evaluation was carried out on 17 pregnancy monitoring mPHRs for iOS and Android. The evaluation consisted of performing a set of tasks and filling in a quality assessment questionnaire that covers the four External quality characteristics: Functional suitability, Operability, Performance efficiency and Reliability. Moreover, 14 mPHRs for pregnancy monitoring were used to study the relationship between the External quality and the Quality in-use by means of four classification techniques: Iterative Dichotomiser 3 (ID3), C4.5, K-nearest neighbors (K-NN) and Naïve Bayes. Results: Functional suitability and Reliability are the most covered quality characteristics by the 17 apps compared to Operability and Performance efficiency. Furthermore, K-NN and C4.5 obtained the highest accuracy rates, as evaluating the accuracy rate of each classification technique can determine if a classifier can be designed to predict the Quality in-use from the External Quality for the apps used in this study. Conclusion: The need of studying the relationship between fulfilling the External quality and the Quality in-use for pregnancy monitoring mPHRs, is of great importance for the developers of these apps for future improvements.


Acid rain, with a pH below 5.6, is a significant global environmental concern with detrimental effects on ecosystems and human activities. It is the result of sulfur dioxide (SO2) and nitrogen oxides (NOx) reacting with water vapor, oxygen, and other compounds in the atmosphere, forming acids that eventually fall back to the ground. Central China has been identified as one of the most heavily impacted regions by acid rain. This paper summarizes the situation and causes of acid rain in Central China, assesses governmental controls, and points out remaining issues and potential solutions. In Central China, sulfuric acid rain forming from SO2 is the predominant form of acid rain, while nitric acid forming from NOx is a minor contributor. The main sources of acid rain that produce SO2 and NOx include the combustion of fossil fuels, certain industrial processes, vehicle exhausts, and agricultural activities. In addition, the pH value of acid rain in Central China also varies seasonally, with the highest pH value in spring and the lowest in autumn, due to different seasonal atmospheric circulation patterns and meteorological factors, which affect the chance of occurrence and the acidity of acid rain.


The dilution hypothesis was tested by adding different concentrations of ambient DOC obtained by solid phase extraction to deep seawater samples. Microbial growth and consumption of DOC were assessed by flow cytometry, HTCO measurements of DOC and oxygen consumption measurements in 14 experiments using water collected from deep water masses of the Atlantic and Pacific Oceans.There are two kinds of experiments 14 (A-N) where prokaryotic growth was evaluated under increasing concentrations of ambient DOC and 2 additional experiments (O and P) where DOC composition and the utilization of different compounds was evaluated by means of Fourier transform ion cyclotron resonance mass spectrometry (FT-ICR-MS). A utilization index for each compound was derived from the FT-ICR-MS fingerprints, showing whether the relative signal for each compound remained stable (refractory or not used), decreased (was consumed) or increased (was produced). Detailed information on conditions and procedures can be found in the article. Enquiries can be sent to Jesus M. Arrieta at txetxu[at]mail.com.


The combination of vision and natural language patterns has become an important topic in the field of computer vision and natural language processing. With the rapid growth of multimodal information, multimodal summarization has received unprecedented attention. In this paper, we propose MTCA which composed of a pre-trained feature extractor, a text encoder, an image encoder, a two-stream cross attention fusion module and a summary decoder to complete the multimodal summarization task. This framework integrates three sub tasks: extractive summarization, abstractive summarization and image selection. At the same time, we introduce a residual network to alleviate the problem of modality-bias. Experiments show that the model is better than the baseline model and the performance is better than the text summarization method which ignores visual modality.


The continuous and isothermal transformation kinetics of 30Cr2Ni4MoV rotor steel were studied in the process of its austenitization.The dilatometric curves with the heating rates from 0.008 to 20 K/s were firstly measured,and the austenitization kinetics analysis was then carried out using Kissinger method according to the non-isothermal Johnson-Mehl-Avrami(J-M-A) phase transformation model.The parameters in the model,including the activation energy for austenitization Q,the pre-exponential factor lnk0 and the J-M-A exponent n,are obtained,for which the values are 2.367×106 J/mol,0.2448 and 270.5,respectively.The isothermal austenitization kinetics curves can thus be determined.The results show that the non-isothermal transformation kinetics contains the information of isothermal transformation kinetics.For the isothermal transformation kinetics curves that are very difficult to be accurately measured due to extremely short incubation period,it can be a feasible and effective way to extract useful information directly from continuous transformation kinetics.


Men might benefit from opportunities specific to their needs in improving access to HIV care. This is a group vulnerable to higher morbidity and mortality than their female counterparts, due not only to poor or delayed health seeking behaviour and the culture of blame for the transmission of HIV, but probably due to neglect, inadequate or poor support by the current policies, by a gender biased research agenda, by the international research community and global health funders.


This paper proposes a framework for the specification of open environment properties.This framework enables convenient and formal specification of properties of asynchronous environments,including temporal properties which cannot be handled in the existing work.This framework also supports implementation of effective schemes for monitoring environment properties based on distributed predicate detection.A middleware infrastructure is designed and implemented,which supports efficient monitoring of environment properties for building high-confidence systems in open environments.This paper also evaluates design of the proposed infrastructure with a case study.


Extension educators have been challenged to be cost effective in their educational programming. The cost effectiveness ratio is a versatile evaluation indicator for Extension educators to compare the cost of achieving a unit of outcomes or educating a client in similar educational programs. This article describes the cost effectiveness ratio and its application in Extension. The major implications are 1) learning ways to reduce the cost of educational programming, 2) making Extension educators aware of the cost of educational programming and guiding ways to maximize the cost effectiveness, and 3) promoting pro-evaluation organizational culture.

In this paper, a non-destructive testing (NDT) method based on the real-time holographic interferometry (RTHI) is used to investigate the dynamic out-of-plane deformation of a commercial based Surface Mounted Assembly (SMT) during power cycling. RTHI provides a precise magnitude (to the order of half the illuminating laser wavelength) to observe the out-of-plane deformation of the leaded SMT assembly, the dynamic deformation history of the assembly, and the out-of-plane deformation of the gull-wing leads and solder joints. Two hard-disk driver boards of the same model, were tested to demonstrate that the RTHI can be used as an efficient quality control tool for reliability testing of solder joints in SMT.


Context. Geodetic very long baseline interferometry (VLBI) has been used to observe extragalactic radio sources for more than 40 yr. The absolute source positions derived from the VLBI measurements serve as a basis to define the International Celestial Reference Frame (ICRF). Despite being located at cosmological distances, an increasing number of these sources are found to show position instabilities, as revealed by the accumulation of VLBI data over the years.
Aims. We investigate how to characterize the astrometric source position variations, as measured with geodetic VLBI data, in order to determine whether these variations occur along random or preferential directions. The sample of sources used for this purpose is made up of the 215 most observed ICRF sources.
Methods. Based on the geodetic VLBI data set, we derived source coordinate time series to map the apparent trajectory drawn by the successively measured positions of each source in the plane of the sky. We then converted the coordinate time series into a set of vectors and used the direction of these vectors to calculate a probability density function (PDF) for the direction of variation of the source position. For each source, a model that matches the PDF and that comprises the smallest number of Gaussian components possible was further adjusted. The resulting components then identify the preferred directions of variation for the source position.
Results. We found that more than one-half of the sources (56%) in our sample may be characterized by at least one preferred direction. Among these, about three-quarters are characterized by a unique direction, while the remaining sources show multiple preferred directions. The analysis of the distribution of these directions reveals an excess along the declination axis that is attributed to a VLBI network effect. Whether single or multiple, the identified preferred directions are likely due to source-intrinsic physical phenomena.

Key to automatically generate natural scene images is to properly arrange amongst various spatial elements, especially in the depth cue. To this end, we introduce a novel depth structure preserving scene image generation network (DSP-GAN), which favors a hierarchical architecture, for the purpose of depth structure preserving scene image generation. The main trunk of the proposed infrastructure is built upon a Hawkes point process that models high-order spatial dependency between different depth layers. Within each layer generative adversarial sub-networks are trained collaboratively to generate realistic scene components, conditioned on the layer information produced by the point process. We experiment our model on annotated natural scene images collected from SUN dataset and demonstrate that our models are capable of generating depth-realistic natural scene image.


【Objective】To explore the relationship between the World Health Organization classification-based prognostic scoring system(WPSS) scores and the clinical manifestation and prognosis of the myelodysplastic syndromes(MDS) patients with or without autoimmune diseases.【Methods】Twenty-three MDS patients with autoimmune disease and fifty-two MDS patients without autoimmune disease were enrolled and followed up.The clinical manifestation,WPSS scores and prognosis were compared and analyzed retrospectively.【Results】Compared with the common MDS patients,the leukemic transformation rate of MDS with autoimmune disease patients did not increased,but the median survival time was shorter.According to WPSS score analysis,in MDS with autoimmune disease patients,the proportion of low/very low risk were relatively smaller,while the proportion of high/very high risk were larger.When WPSS score was the same,there was no significant difference of survival time between the two groups.【Conclusion】Comparing with common MDS patients,the relatively shorter median survival time of MDS with autoimmune disease patients was related to their higher risk proportion.Patients of MDS with autoimmune disease was a highly heterogeneous group.WPSS score might be a powerful predictor of prognosis for MDS with autoimmune disease patients.


The intergovernmental relationship in Germany assumes the cooperative modules involving interdependency.It formulation was the result from the interaction of multiple elements.In this module,state governments and local governments are involved in policy making,thus exerting influence upon the federal government.The federal government also utilizes financial means to control its membership units,and intervenes in the affairs of the state governments and local governments.The intergovernmental relationship in Germany is also embodied in the authoritative relationship between state governments and local governments as well as the horizontal relationship between state governments and local governments,showing the increasing tendency of the expansive power of the local governments.The coordinative mechanism in the intergovernmental relationship secures the communication and coordination between governments,avoid and resolving the intergovernmental conflicts,and guarantees the harmonious development of German society.The intergovernmental adjustment and reform will continue along with the political,economic and social development of Germany.


Using high-resolution spectra obtained with the Hamilton echelle spectrograph at Lick Observatory, we have constructed a catalog of emission lines observed in comets Swift-Tuttle and Brorsen-Metcalf. The spectra cover the range between 3800 A and 9900 A with a spectral resolution of λ/Δλ~42000. In the spectra, we catalog 2997 emission lines of which we identify 2438. We find cometary lines due to H, O, C_2, CN, NH_2, C_3, H_2O^+, CH, and CH^+. We list 559 unidentified lines compiled from the two spectra and comment on possibilities for their origins.


The essay is a kind of social science fiction meant to commemorate the 100th anniversary of Emile Durkheim's death in 1917. Durkheim's ghost, therefore, is used to imagine how his thinking would have dealt with the actual premodern and modern histories of France, Germany, and Turkey


There are more than 5,200 independent oil and gas producers operating in the US today (based on current IPAA membership figures). These companies are playing an increasingly important role in production of hydrocarbons in California and elsewhere in the US. Pacific Operators Offshore, Inc., in a historic collaboration with its government royalty owners, the California State Lands Commission and the Minerals Management Service of the US Department of Interior, is attempting to redevelop the Carpinteria Offshore Field after two-and-a-half decades of production and partial abandonment by a previous operator. This paper will describe a project which focuses on the distribution of advanced reservoir management technologies (geological, petrophysical, and engineering) to independent producers like Pacific Operators Offshore, Inc. The evolving information highway, specifically the World Wide Web (WWW), serves as the distribution medium. The project to be described in this paper is an example of the implementation of a reservoir management tool which is supported by distributed databases, incorporates a shared computing environment, and integrates stochastic, geological, and engineering modeling.


Dominant mutations in TPM3, encoding α-tropomyosinslow, cause a congenital myopathy characterized by generalized muscle weakness. Here, we used a multidisciplinary approach to investigate the mechanism of muscle dysfunction in 12 TPM3-myopathy patients. We confirm that slow myofibre hypotrophy is a diagnostic hallmark of TPM3-myopathy, and is commonly accompanied by skewing of fibre-type ratios (either slow or fast fibre predominance). Patient muscle contained normal ratios of the three tropomyosin isoforms and normal fibre-type expression of myosins and troponins. Using 2D-PAGE, we demonstrate that mutant α-tropomyosinslow was expressed, suggesting muscle dysfunction is due to a dominant-negative effect of mutant protein on muscle contraction. Molecular modelling suggested mutant α-tropomyosinslow likely impacts actintropomyosin interactions and, indeed, co-sedimentation assays showed reduced binding of mutant α-tropomyosinslow (R168C) to filamentous actin. Single fibre contractility studies of patient myofibres revealed marked slow myofibre specific abnormalities. At saturating [Ca(2+)] (pCa 4.5), patient slow fibres produced only 63% of the contractile force produced in control slow fibres and had reduced acto-myosin cross-bridge cycling kinetics. Importantly, due to reduced Ca(2+)sensitivity, at sub-saturating [Ca(2+)] (pCa 6, levels typically released during in vivo contraction) patient slow fibres produced only 26% of the force generated by control slow fibres. Thus, weakness in TPM3-myopathy patients can be directly attributed to reduced slow fibre force at physiological [Ca(2+)], and impaired acto-myosin cross-bridge cycling kinetics. Fast myofibres are spared; however, they appear to be unable to compensate for slow fibre dysfunction. Abnormal Ca(2+)-sensitivity in TPM3-myopathy patients suggests Ca(2+)-sensitizing drugs may represent a useful treatment for this condition. © The Author 2015. Published by Oxford University Press.

It is well-known that plate motions and the elevation of mountains belts have played a major role in palaeoclimate evolution. The present day monsoon in southeast Asia and northern Australia is associated with the Tibetan plateau. We investigate how the Miocene Climate Optimum (MCO) developed in response to altimetry changes in Eurasia and South America impacting changes in regional monsoon, wind stress and precipitation. We carried out a number of numerical experiments with alternative paleo-altimetries, using an updated NCAR coupled climate model, CCSM3, and CAM3.1 and CLM3 with slab ocean and ice models, validated with proxies. Our model results explore the sensitivities of regional climate change to plate motions and rising mountain belts as well as sea-level change. Especially, the model simulations ground-truth the monsoon evolution in the southeast Asia, northern Australia and South America.


The invention relates to a process for producing high-density spherical cobaltosic oxide by virtue of low temperature liquid phase precipitation oxidization. The process comprises the following steps of: firstly preparing a cobalt chloride solution with the cobalt content of 60-75g/l and a sodium hydroxide solution with the concentration of 100-120g/l, adding the two solutions into a reaction tank in a parallel flow mode, introducing the air to carry out a synthetic reaction, controlling the reaction temperature to be 35-50 DEG C and pH value to be 11.3-12.5, and reacting for 10-20 minutes; adding EDTA (ethylene diamine tetraacetic acid) into an ageing tank according to the ratio of cobalt to EDTA being 100: (1-5) while ageing, and then filtering, slurrying and washing after ageing so as to obtain a wet cobaltosic oxide solid, and finally calcining the wet cobaltosic oxide in a calcining furnace for 3-5 hours at the temperature of 300-500 DEG C, taking out the cobaltosic oxide, and sieving to obtain cobaltosic oxide powder. In the invention, the production process is controllable, the product has uniform particle size distribution, good uniformity, spherical appearance and good dispersity and stability, the recovery rate is high, the energy source and resource are saved, the production cost is low, the compaction specific gravity is high, and the reliable safety performance isobtained.


Proteolysis could not be detected, prior to the appearance of spoilage odours and surface slime, in beef allowed to spoil aerobically at 5° with its own natural flora or after inoculation with a reconstituted freeze-dried beef slime. Although the slime inoculum gave a final microbial flora similar to the naturally-attained one, it resulted in more rapid and extensive post-spoilage proteolysis. Pure culture experiments showed that proteolysis was probably due to the activities of Gram negative organisms.

ALTHOUGH CONE CROPS of loblolly pine fluctuate widely from year to year, they are more or less uniform over extensive territories in any one year. This uniformity gives rise to the familiar term '' eed year." If seed years could be pre dicted well in advance, the infor mation would be extremely useful in planning cone collections and regeneration measures. Prediction, however, requires an understand ing of the basic causes of cone crop fluctuation, which have re ceived little tudy becau e quanti tative data are difficult to obtain. Seed-trapping record in the Bigwoods Experimental Forest from 1946 to 1953 provided suffi cient data for tudying the e causes. Only the records from ma ture, undisturbed stands were used. because the e most clearly reflect the factor affecting size of seed crop<;. In immature stand , the year-to-year variation of seed crop is modified by the stand 's yearly prog-ress toward maturity; in par tially cut stands by the effect of release; and in isolated trees by the probability of inadequate pol lination. Stands must also be in stable and sympathetic ownership so that tbev can be withheld from cutting long enough to yield a suffi cient number of observations.


Abstract : The thesis develops analytic models for estimating the amount of memory interference in multiprocessor systems, in which n processors access m memories independently. The processors are characterized by a typical processing time per memory access and the memories by an access time and rewrite time. Processor behavior is simplified to an ordered sequence of a memory request followed by a certain amount of processing. The predominant technique used involves discrete time Markov chain models. Some simple exponential server models as well as several approximate models are also presented. Simulation is used to evaluate the accuracy of the approximate models. Some empirical measurements of the PDP-11/20 are used to estimate the parameters of a model, that is used to predict the performance of C.mmp, Carnegie-Mellon University's multiprocessor computer, which will include up to 16 PDP-11 processors.


The focus of the study was on sorbents with a grain size of 125-250 μm. Examinations of reactivity were conducted in a reaction furnace under conditions required for reactivity testing of calcium sorbents. The tests were performed according to standard calcium sorbent tests (FW). Computation of reactivity indices and capacity index were performed according to formulae contained in previous publications [1]. The process of simultaneous calcination and sulfation of calcium sorbents is controlled by the speed of chemical processes and diffusion. Therefore, surface properties of sorbents, including porosity, play an important role in the flue gas desulphurization process. Examinations of sorbent porosity were performed using a mercury porosimeter. Based on porosimetric analysis, open porosity, the total surface area of sorbents and mean diameter of pores were evaluated for the sorbents studied.

Finally, the article concludes with a discussion on the imperative to establish a Centre of Excellen...


Optically efficient europium activated alkaline earth metal tungstate nano phosphor (SrWO4) with different doping concentrations have been synthesized by mechanochemically assisted solid state metathesis reaction at room temperature for the first time. The XRD and Raman spectra results indicated that the prepared powders exhibit a scheelite-type tetragonal structure. FTIR spectra exhibited a high absorption band situated at around 854 cm−1, which was ascribed to the W–O antisymmetric stretching vibrations into the [WO4]2− tetrahedron groups. Analysis of the emission spectra with different Eu3+ concentrations revealed that the optimum dopant concentration for SrWO4: x Eu3+ phosphor is about 8 mol% of Eu3+.The red emission intensity of the SSM prepared SrWO4: 0.08Eu3+ phosphors are 2 times greater than that of the commercial Y2O2S: Eu3+ red phosphor prepared by the conventional solid state reaction method. All the results indicate that the phosphor is a promising red phosphor pumped by NUV InGaN chip for fa...


PURPOSE
beta-1,4-Galactosyltransferase (beta-1,4-GalT) I, II, and V are the enzymes responsible for the biosynthesis of N-acetyllactosamine on N-glycans by transferring UDP-galactose to the terminal N-acetylglucosamine (N-GlcNAc) residues with the formation of a beta-1,4-linkage. Neoplasms undergo various changes in the carbohydrate of their glycoconjugates, indicating the possible changes in glycosyltransferases themselves.

METHOD
Therefore, we compared the expression of beta-1,4-GalTs between astrocytoma and normal brain tissues.

RESULTS
Our reverse-transcription polymerase chain reaction (RT-PCR) results showed that beta-1,4-GalT I transcript was absent in normal adult brain but detectable in grade II, III, and IV astrocytomas; the level of beta-1,4-GalT II transcript was increased in grade II, III, and IV astrocytomas while only a trace amount was found in normal brain; beta-1,4-GalT V transcript existed in normal brain and increased in the process of astrocytoma progress, with the highest level in grade IV astrocytoma. By Ricinus communis agglutinin-1 (RCA-1) lectin blot assay, we also found the more extensive galactosylated bands in astrocytomas compared with normal brain. A major 61kD protein was galactosylated in astrocytoma but not in normal brain tissues.

CONCLUSION
These results indicate that the increase of galactosylation in astrocytomas may be caused by the alterations of gene expression of beta-1,4-GalT I, II, and V and that the malignant degree of astrocytoma is correlated with the expression of beta-1,4-GalT V.


Tunnel Boring Machine (TBM) tunneling projects are frequently hit with delays which can cause adverse effects, extending schedules and incurring additional costs. This paper outlines a case study to show how simulation can be effectively used to analyze productivity performance of a project with emphasis on delays from equipment breakdowns and unexpected conditions. Data collected from this project under a Method Productivity Delay Modelling study, completed by a consulting firm, was collected and prepared to model delays on a combined discrete event continuous tunneling simulation model. Calibration was done to the theoretical tunneling model to ensure the results would be reflective of the actual construction project and to measure the effectiveness of the delay modelling. Sensitivity analysis was conducted to distinguish the most unfavourable delays to a tunneling project, allowing further analysis into the results of the mitigation of these delays on project duration and hypothetical costs.


Objective:To observe the feasibility and safety of dexmedetomidine versus that of midazolam applied in auxiliary sedation during brachial plexus blockade.Methods:Eighty cases of selective surgery patients undergone brachial plexus anesthesia were divided randomly and double-blindly into groups A,B,C,and D,which were anaesthetized by midazolam,micro-pump dexmedetomidine, micro-pump dexmedetomidine combined with midazolam,and the load dose and micro-pump dexmedetomidine respectively.MAP,HR,and OAA/S score were recorded before anesthesia (T_0),10 min(T_1),20 min(T_2),30 min(T_3),60 min(T_4) during anesthesia,and at the end of operation(T_5).Results:Compared with that respectively at T_0,MAP,HR,and OAA/S score at T_1 decreased in group A(P0.05),during T_1-T_5 in group B were stable(P0.05),and during TVT,,in group C and group D decreased more apparently(P0.05).While compared with that respectively in group B,MAP,HR,and OAA/S score during anesthesia(T_1-T_4) decreased in group C and group D(all P0.05),and the decrease of these indices was much more significant in group D than in group C(all P0.05).Conclusion;During brachial plexus blockade, dexmedetomidine combined with midazolam shows satisfying sedative effect,reduces the side effects,and the vital signs of patients during anesthesia are stable.


Introduction: breast cancer is common in women living in developed countries. Cuba does not escape from this problem. Objective: to characterize breast cancer clinically and histologically at Abel Santamaria Cuadrado General Teaching Hospital in Pinar del Rio during the period 2009-2014. Method: a descriptive and retrospective study with a target group that included all women with histopathological diagnosis of breast cancer that were recorded on Pathological Anatomy Book of the above mentioned hospital (N = 604), and the sample included patients with breast cancer histologically confirmed (n = 352); age, tumor size and histological features were considered according to the degrees of Bloom-Richardson's classification system. Results: the largest tumor diameter was 2-4.9 cm, the majority of the cases histologically diagnosed presented duct carcinoma, and the greatest incidence of tumors occurs between 55-64 years old (21.9%). Conclusions: breast cancer is commonly detected in Pinar del Rio province among women between the fourth and seventh decades of life. Nodules measuring less than 5 cm. and the variety of duct carcinoma were the most frequent.


The spatial distribution of active accumulated temperature ≥10℃(AAT10) was simulated by using the multiple linear regression model(MLRM) and IDW, Kriging, Spline interpolation method based on the daily meteorological observation data from 111 meteorological stations in Southern China and surrounding areas during 1980 to 2011. The result shows that compared with the conventional methods such as IDW, Kriging and Spline, it solves the complexity of the spatial distribution of AAT10, and considers the elevation, longitude and latitude differences to AAT10. It shows higher simulation accuracy,and is suitable for a wide range of spatialization of accumulated temperature. At the same time, the AAT10 in South China was reduced with increasing altitude from 1980 to 2011; and reduced with increasing latitude. There is a large variation with longitude in the western Yunnan region affected by the impact of changes in topography, and a little variation with longitude in the eastern part of Guangxi,Guangdong, Fujian province.

For a long time it has been acknowledged that one of the principal determinants of Giotto's style was antique sculpture. The often-cited articles by A. Bush-Brown and Anne Markham Telpaz laid the foundations of this aspect of Giotto studies, but little has been added to their insights.1 Only Alastair Smart, in his book on the frescoes of the legend of Saint Francis at Assisi,2 has substantially extended the dis


Abstract Two similar molecular building blocks, which both contain a hydrogen‐bonded nitro group, have been prepared and crystallised. One structure has more flexibility with a butyl side chain which allows an open framework organic zeolite to form with large 10 Å diameter pores, whereas the other structure has less flexibility with an aryl side chain and is close packed. The pore size is comparable with those of the aluminophosphate VPI‐5 (12 Å). It is concluded that some flexibility in the design of the building block for porous organic molecular materials was beneficial.


The Florida State University (FSU) multimodel superensemble forecast is evaluated against several other operational weather models for the Southeast Asia region. The superensemble technique has demonstrated its exceptional skills in forecasting precipitation, motion and mass fields compared to either individual global operational or ensemble mean forecasts. The motion field investigation for the season of 2001 reveals that the superensemble forecasts are closer to the observed data compared to the other global member operational models through its low systematic errors at the 850 hPa level. The FSU multimodel superensemble forecasts exhibit the lowest root mean square errors (RSMEs), the highest correlation against the best observed data and the lowest systematic errors compared to the other operational model members. These forecasts have the potential to provide better daily weather predictions over the Southeast Asia region, particularly during the early northeast monsoon that often causes heavy rainfall in the equatorial part of the Southeast Asia region.


The short-term real and reactive power optimization of a large system is a non-linear programming problem and its solution requires a considerable amount of computational effort. In actual practice separate real and reactive power suboptimization techniques may be more suitable than a complete optimization(1). The results obtained by the suboptimal techniques under ideal conditions coincide with those from a real and reactive power optimization. In this paper, complete real and reactive optimization has been solved by suboptimization techniques. The proposed approach decomposes the complete problem into two halves, i. e. the optimum voltage evaluation and the real power optimization with optimally determined voltages. A theoretical treatment of the technique along with a qualitative and analytical discussion is provided. The method is applied to a small system and the results obtained are compared with a real and reactive power optimization.


Slide attack on MISTY1 variants is presented by analyzing the schedule of the subkeys.On the one hand,with ignoring the FL layers,there are related keys of MISTY1 for the slide attack,which requires 222 chosen plaintexts with the time complexity being 235.5 encryptions.On the other hand,by resetting the subkeys in the FL layers,the slide attack also can be used to attack on MISTY1 variant with the FL layers,which requires 242 chosen plaintexts with the time complexity being 251.3 encryptions.Performance analysis shows that the FL layers play an important role in MISTY1.


Abstract Although the emergent critical enterprise loosely termed "Whiteness Studies" has generated controversy among U.S. race scholars, few would disagree that one of its continuing contributions to contemporary discussions of race is the insistence that the racial category of whiteness be demystified-that its hegemonic contrivances be made visible.


In the history of Polish Catholic media a significant role falls to the Catholic Press Agency (KAP) which operated in the years 1927–1939. The author of the article presents the political context of the journalistic activity of KAP under the leadership of Fr. Zygmunt Kaczynski in the light of the research material collected in the Vatican archives. The case of Fr. Kaczynski offers a suitable starting point for more general reflections on the complex problem of the impact of the political views of the editor-in-chief over against the requirement of an objective description of reality. The agency's journalistic activity meant dealing with topics of a social and political nature, but the clearly declared political views of its director were perceived as a support of one political party and criticism of the government camp. From the relevant source material it follows that even within the Episcopate there was no unanimous opinion on Fr. Kaczynski, as evidenced by the extreme stances of Cardinal August Hlond and Cardinal Aleksander Kakowski.


This study reports the effect of bias on the Zone T structure of TiB_2 films deposited on steel substrates using magnetron sputtering technique.X-ray diffraction,scanning electron microscopy analysis have been used to characterize the films' properties.The(001) crystal orientation is characteristic of the films irrespective of the deposition process in our work.Using the nanoindentation testing,the hardness and ratio H~3/E~(*2) values of the films are 50GPa and 0.65GPa under-50V bias.With increasing the negative bias voltage,the grain size decreases,the hardness and resistance to plastic deformation(H~3/E~(*2)) decrease as well.The SEM analysis shows that the substrate temperature has a strong effect on Zone T structure.An increase in the substrate temperature promotes ''equiaxed'' grain structure in TiB_2 thin films as T_s/T_m is 0.18.


Many species of worm are parasitic and have humans as their hosts. In developing countries worm infestations are a major problem and can result in growth deficiencies in children, deformities and blindness, and organ damage. Fortunately the UK is not affected by species of worm that cause such problems but infestations by less harmful species exist. Parasitic worm (helminth) infestations are caused by three groups of worms: nematodes (roundworms), trematodes (flukes) and cestodes (tapeworms) — see Panel 1 for examples.The most common worm infestation in the UK is threadworm. Large roundworm (commonly simply referred to as roundworm), hookworm and whipworm infestations are endemic in tropical and subtropical countries and in the UK they are usually found in immigrants or travellers. The increasing popularity of travel to exotic destinations could lead to an increase in these types of infestation. Pharmacists should be aware that such travel could also expose people to the risk of other tropical worm infestations, such as schistosomiasis (see Panel 2, p344).


In this paper we study some parameters of domination, independence and irredundance in some edge-coloured graphs and their products. We present several general properties of independent, dominat- ing and irredundance sets in edge-coloured graphs and we give relation- ships between the independence, domination and irredundant numbers of an edge-coloured graph. We generalize some classical results concern- ing independence, domination and irredundance in graphs. Moreover we study G-join of edge-coloured graphs which preserves considered parame- ters with respect to related parameters in product factors.

The invention is directed to optical elements of calcium fluoride crystals with improved laser resistance, which can be used for transmission of electromagnetic radiation below 250 nanometers (nm). The optical elements consist of CaF 2 as the main constituent and Mg in an amount in the range of 13 ppm to 20 ppm, while Ce and Mn are less than 0.5 ppm. The doped crystal and the optical elements made therefrom have a ratio of transmission loss at 515/380 nm of less than 0.3 after exposure to gamma rays of more than 2.8 MRads. Furthermore, the doped crystal and the optical elements made therefrom show a significantly improved lifetime, as shown by an ALDT test with at least 1 billion pulses.


The influence of the viscosity of the medium on the rate and efficiency of a chemically initiated graft copolymerization with styrene and methylmethacrylate was studied. The increase in viscosity was reached partly by formation of the respective homopolymers, partly by the atactic polypropylene. The transfer constant to the atactic polypropylene from growing polystyrene macroradicals and the ratio of the rate constants of reaction of primary radicals with atactic polypropylene and with styrene were determined. It was found that the total efficiency of grafting styrene to atactic polypropylene increases with increasing concentration of polypropylene in the initial mixture and that the conversion of monomer is not a major influence in this case. On the contrary, for grafting of methyl methacrylate to atactic polypropylene a decrease of total efficiency with conversion of monomer was observed. This indicates that the gel effect is not only a function of viscosity of medium but also of the character of polymers in the reaction mixture.


The master graduation project is carried out to help the Dutch company Priva find out the market opportunities in China for her LWE (living and working environment) segment in the Chinese market. Figuring out if Chinese building automation market will be valuable for Priva to enter in now and what product and marketing strategy should be designed was the main objective of this project. Six research questions are designed to guide the research process, which will be answered in the six chapters in this report. Chapter one gives on overview of the building management system industry background knowledge. It is known that the building management system products have intimate relationship with the building market and is part of the intelligent building system which is very dependent on system integrators. In the building value chain in China, there are six stakeholders, four of which have certain influences on the decision making of building automation facilities—the project investor/building owner, Facility managers, designers, building end users. Chapter two introduces the current product portfolio and business strategy of Priva and analyzed the core competence of the company. Currently Priva is very dependent on partners which provide sales channels for the company and integrate product components into an entire building energy management system for the building owner. The core technology competence of Priva is the good quality of the hardware products and outstanding design and user experience of the software products. Chapter three describes the situation of Chinese building management system market, segments the building market as the future building management market, and selects the hospital vertical market for Priva as the niche market segment. A market entry decision is suggested and a new product design is required to meet the market demands. Chapter four shows the new product concept generation process. The hesitant customer group in the Chinese hospitals is selected as the target customer group of Priva. Product functions and working principles are designed according to the user needs research and previous results of company analysis and market analysis. The design is a combination of a software product and a set of simple physical modules. The product is independent on the system integrators and used to create the awareness of the connection between the comfort management and the energy management. Chapter five provides future recommendations on the business model of the new product and a licensee strategy is suggested. How to design the product details and user experiences and how to find a new partner in the Chinese market are the future research fields.

Banks now are facing strong competition from both technological giants and small fintech startups. Under these conditions, banks also have started to implement disruptive technologies in their day-to-day operations. However, in some cases huge investments in different technological systems do not lead to the increase in company performance due to the resistance of employees. In this chapter, we focus on both internal and external factors that may influence employees' labor productivity and performance of the whole company. The sample includes 148 employees with education in banking and finance. The model was estimated based on Partial Least Squares Structural Equation Modelling (PLS-SEM). We show that both motivation to use disruptive technologies and digital skills have a strong impact of labor productivity, while both labor productivity and organizational support positively contribute to the improvement of company performance that is based on the usage of new technologies.


Plasmonic superradiance originates from the plasmon mediated strong correlation that builds up between dipolar emitters coupled to a metal nanoparticle. This leads to a fast burst of emission so that plasmonic superradiance constitutes ultrafast and extremely bright optical nanosources of strong interest for integrated quantum nano-optics platforms. We elucidate the superradiance effect by establishing the dynamics of the system, including all features like the orientation of the dipoles, their distance to the particle and the number of active plasmon modes. We determine an optimal configuration for Purcell enhanced superradiance. We also show superradiance blockade at small distances. PACS numbers: Introduction. In a seminal work, Dicke discovered that a set of N e atoms radiate collectively when they occupy a subwavelength volume. Their emission is much faster (τ Ne = τ 1 /N e) and stronger (I Ne = N 2 e I 1) than for independent atoms. This so-called superradiance originates from spontaneous phase-locking of the atomic dipoles through a same mode and is very similar to the building of cooperative emission in a laser amplifier [1]. Superradiant emission produces original states of light with applications such as narrow linewidth lasers [2] or quantum memories [3, 4]. Single collective excitation of atoms in a nanofiber has been demonstrated [5] and superradiant-like behaviour was suggested in a plasmon-ics junction [6] or a nanocrystal [7], pushing further integration capabilities of quantum technologies. Putso-vits and Shahbazyan identifyed plasmon enhanced collective emission for dipoles coupled to a metal nanopar-ticle (MNP) [8], considering a classical approach which however cannot describe the Dicke cascade at the origin of the cooperative emission. In this communication, taking benefit from recent advances on quantum plasmonics and open quantum systems [9-17], we derive a quantum approach for plasmonic superradiance and discuss the dy
