ABSTRACT The new information age and the phenomena of digitalization and automation make investments in research and development (R&D) indispensable for economic and social progress. Meanwhile, increased inequality within countries and its effects on advanced countries is one of the consequences of the recent turbulences in the global economy. These two dynamics open debates around the still-unresolved nature of the relationship between innovation and inequality. This paper contrasts postulates from the existing theory and relevant empirical evidence to argue that the analysis of the positive and complex co-evolution of inequality reduction and technological progress in Europe implies a recombination of factors that highlights institutions as the backbone of the relationship. The results of this analysis based on time series / cross-section regressions with panel data from a sample of 20 European countries for the period 1995–2017 show the relevance of structural and institutional aspects within the region, while two sets of countries evince a dissimilar European behavior in the relationship under study. According to our findings, it is plausible to argue the existence of a virtuous circle defined by the combination of social protection contributions with innovation policies that certainly help settle the controversial relationship between innovation and inequality.

The RV Tauri stars are semiregular variables whose light curves are characterized by alternate deep and shallow minima. On the basis of light curve the RV Tauri stars are divided into the RVa group and the RVb group. The RVb group is characterized by a long-term light variation superposed on pulsation period. The RVa group do not show such a long-term variation. On the basis of spectroscopic characteristics in an optical region the RV Tauri stars are divided into the oxygen-rich group, the group A, and the carbon-rich group, the group B and the group C. We newly rnade the spectropolarimetric observations of 4 bright RV Tauri stars, SS Gem, U Mon, CT Ori, and RV Tau, usiRg 188cm reflector attached with the spectropolarimeter (1{BS) at the Okayama Astrophysical Observatory of the National Astronomical Observatory in Japan. We determined intrinsic polarizations for these stars by removing interstellar polarizations and we obtained the following results about the wavelength dependence of intrinsic polarization. 1) There are three types of wavelength dependence of intrinsic polarization of SS Gem observed with HBS. These dependences seem to be due to the difference in phase of the formal period. 2) There are four types of wavelength dependence of intrinsic polarization of U Mon observed with HBS. These wavelength dependences seem to be due to the difference in phase of long-term light variation. 3)The wavelength dependence of CT Ori observed with HBS is the same as that observed wi癒the multi-channel polarimeter (MCP) . Therfore, the intrinsic polarization of CT Ori seems to be constant with time. 4) There are four types of wavelength dependence of intrinsic polarization of RV Tau observed with HBS. These wavelength dependences seem to be due to the difference in phase of long-terin light variation, though this correlation between the wavelength dependence and the long-term phase observed with HBS is quite different from that observed with MCP. 要 旨 おうし座RV型星は、主極小と副極小を交互にくり返す光度変化に特徴がある半規則的な変光星である。この変光 星は、光度曲線をもとにRVa型とRVb型に細分類されており、RVb型が脈動周期に重なって長周期の光度変化を示す のに対して、RVa型はそのような長周期変化を示さない。またこの変光星は可視域のスペクトルをもとに、酸素過剰 なAグループと炭素過剰なB,Cグループに細分類されている。 われわれは、岡山天体物理観測所の188cm反射望遠鏡に偏光分光測光装置(HBS)を取り付けて、明るい4個のお うし座RV型星の偏光分光観測を行った。そして、それぞれの星に対して星間偏光を差し引いて固有偏光を求め、固 有偏光の波長依存性に関して次の結果を得た。 (1)H:BSで求めたふたご座SS星の固有偏光の波長依存性には3つのタイプがある。それらは脈動変光の位相の違い によると思われる。 (2)HBSで求めたいっかくじゅう座U星の固有偏光の波長依存性には4つのタイプがある。それらは長周期光度変化 の位相の違いによると思われる。 (3)HBSで求めたオリオン座CT星の固有偏光の波長依存性は、多色偏光測光装置(MCP)で求めた結果に等しい。 したがって、オリオン座CT星の固有偏光は時間的に一定と思われる。 1>放送大学教授(「自然と環境」コース)

Abstract Florence Nightingale, the 'lady with the lamp' became the image of 'heroic womanhood' (Bostridge 2004) when she returned from the Crimean War an iconic figure and ever since she has remained fated to wear the mantel of nursings' leading light. But she wasn't the only woman who made their mark or who undertook to risk their lives caring for the sick and injured, wounded and dying in the Crimea. Sadly, Nightingale's iconic status has also succeeded in overshadowing the existence and the achievements of the many others who nursed during the Crimean war. These women, nuns, ordinary nurses, lady volunteers and others, working in Nightingale's shadow, contributed much to the comforts of the wounded and dying and this article seeks to illuminate their presence and contribution. It also highlights other aspects of Nightingale's work and in doing so, allows us to look into the shadows and shed more light on the others who were also there. Key points • Florence Nightingale is the most famous nurse to have returned from the Crimean War, but many others contributed much and sadly Nightingale's iconic status has overshadowed others' contribution. • Although Florence Nightingale contributed much during her time in the Crimea, her greatest influence on nursing resulted from her writings in the last 40 years of her life. • Three groups of officially sanctioned nurses travelled to the Crimea, lady volunteers, nuns and ordinary, paid nurses. • Others nurses travelled to the Crimea as unofficial nurses, the most famous being Mary Seacole. • Their contribution and recognition is often overlooked because of the iconic status achieved by Florence Nightingale. • It is easy to loose sight of the many nurses at the bedside and on the frontline of care whose contribution to patient wellbeing is central, but often overshadowed by the glare of Government agendas, health service targets or financial burdens.


Background: Street vended foods contaminated with antibiotic resistant bacteria poses a great public health concern in developing countries like Bangladesh as foodborne diseases caused by such bacteria are difficult and sometimes impossible to treat. The aim of this review is to investigate the present scenario of the antibiotic resistance status of five selected Gram negative bacteria isolated from a variety of street vended foods of Bangladesh.
Methodology: A methodical literature search was performed to identify relevant studies on Google Scholar, Science Direct and Research Gate using suitable keywords arranged in different manners to produce a meaningful search string. Weighted mean resistance was calculated to evaluate the resistance status from 20 studies selected through the PRISMA procedure.
Results: Escherichia coli, Klebsiella spp., Salmonella spp., Pseudomonas spp. and Vibrio spp.  showed relatively low resistance towards imipenem and gentamicin, whereas the antibiotics of penicillins and macrolides classes listed in this review were mostly ineffective. Relatively high resistance was found against tetracycline, vancomycin, and rifampicin.
Conclusion: A considerable number of bacterial isolates present in the SVF are resistant to most of the commonly used antibiotics. Therefore, there is an urgent need for public awareness along with a robust national action plan to combat antibiotic resistance, before the situation worsens.

In the past few years, many high-throughput screening (HTS) technologies together with significant efforts to develop diagnostics tools such as biosensors have revolutionized the process of drug discovery to screen hundreds of thousands of compounds against disease targets to find novel drugs. Typically HTS studies are performed through a combination of modern robotics, data processing and control software, liquid handling devices, and sensitive detectors. However, robots and other equipment required for HTS studies are often expensive. Large volumes of cost-intensive chemicals are required to perform such tests. Another limitation is the time it takes to assay individual samples. In the end, even as these sets of facilities are fixed, the experimental data are not reliable for clinical application and, therefore, animal testing and clinical trials are required in order to get approval for the product (drug) after a very long processing time. The above problems are among the many limitations of current technologies using materials in many aspects of biological applications. Despite considerable effort at developing methods to enable testing of many conditions, it still takes a highly specialized and expensive screening lab to run a HTS operation, and these studies often are limited to large or moderately sized research institutions. The purpose of our study is to use microengineering, biomaterial sciences, and biological principles to develop 3D in vitro living organs with controlled microvasculature and tissue architecture. These 3D models will be useful for in vitro diagnostics and drug screening applications as well as for transplantation. Furthermore, 3D in vitro living organs contribute significantly to the development of microscale biosensors that will be more portable and scalable for pointof-care sample analysis and real time diagnosis. Modern biosensors based on microand nanoscale techniques have the potential to greatly enhance methods of detecting foreign and potentially dangerous toxins and may result in cheaper, faster, and easier to use analytical tools. Microscale technologies are potentially powerful tools for addressing some of the challenges in 3D in vitro models. MicroElectroMechanical Systems (MEMS), which are an extension of techniques used in the semiconductor and microelectronics industries, can be used to control features at length scales <1 μm to > 1 cm3. In the past few years, microfabrication has been used increasingly in biomedical and biological applications. This is partially due to the emergence of such techniques as soft lithography to fabricate microscale 3D In Vitro Living Systems for Biological Application


The National Commission on Writing for America's Families, Schools, and Colleges (2006) specifies that writing-across-the-curriculum programs (including post-secondary coursework) should be well supported. They also challenge teacher preparation programs to provide opportunities for "teachers already in the classroom to upgrade their writing skills and competence as writing teachers" (p. 65). Yet many classroom teachers do not feel comfortable teaching writing, nor do they feel knowledgeable about how to use writing with students (Murphy, 2003; Napoli, 2001; Street, 2003). This lack of confidence may be due to the fact that teachers are heavily influenced by their own histories as writers (Mathers, Kushner-Benson, & Newton, 2007; Street, 2003). From Lortie (1975) onwards, research has consistently reported on the powerful influence that teachers' preexisting attitudes about teaching exert on their learning (Clifford & Green, 1996; Florio-Ruane & Lensmire; Grossman et al., 2000; Schmidt & Kennedy, 1990; Shrofel, 1991). Since "teachers enter their professional education already trapped in their own relationship with the subject" (Kennedy, 1998, p. 14), the writing attitudes and experiences that they bring with them to the university may be difficult to change. The National Writing Project (NWP) is a group that understands this issue, believing that teachers must be comfortable and confident with writing before they can feel a sense of competence with the teaching of writing (Bratcher & Stroble, 1994). As suggested by the NWP, until teachers know as insiders what writing is like, they will never truly be able to teach their students to write well. With this consideration in mind, every attempt is made to immerse NWP teachers in the role of authors, asking them to experience writing from the inside out. As chronicled by Lieberman and Wood (2002), "Core activities during the summer institutes include sharing best lessons or strategies, participating in small writing groups, and receiving peer feedback" (p. 40) from their colleagues. A substantial body of research suggests that most teachers are not prepared to use writing with their students (National Commission on Writing, 2003, 2006; National Writing Project & Nagin, 2006). When teachers do experience professional development in this area, it is often a single workshop devoted to writing across the curriculum or is not specific to the individual needs of the teacher (Lieberman & Wood, 2003; National Writing Project & Nagin, 2006). This is unfortunate, since teachers serve as a crucial link in the continued move to improve the literacy skills of K-12 students (Allington & Johnston, 2000; Darling-Hammond, 1997; Joyce & Showers, 2002; Instersegmental Committee, 2000; National Commission on Writing, 2003, 2004, 2005, 2006; National Writing Project & Nagin, 2006). Though the need for professional development in writing is apparent, research on models of professional development in this area are sparse. However, the National Writing Project has emerged as one highly effective model of professional development, offering teachers the kind of support that research suggests that they require (Bratcher & Stroble, 1994; Lieberman & Wood, 2002, 2003; National Writing Project, & Nagin, 2006; Raymond, 1994; Street, 2003; Street & Stang, 2008). The NWP model of professional development addresses the issue of how to build teachers' self-confidence as writers in the context of offering them meaningful and sustained professional development. The NWP realizes that professional development needs to begin where the teachers are, acknowledging that the writing histories of teachers are a vital consideration when working with teachers. As is evidenced from research, the writing histories of teachers play an important role in their ability--or inability--to use writing with their students (Bratcher & Stroble, 1994; Chambless & Bass, 1995; Pajares, 1996; Pajares & Johnson, 1994; Street, 2003; Tschannen-Moran & Hoy, 2001). …

Lake Ohrid in southeastern part of Europe is one of the few ancient, long-lived lakes of the world. This is a transboundary lake shared by Macedonia and Albania, situated between mountain ranges to the east and west. It is a deep lake with a large surface area. In order to obtain information about its trophic state were carried out investigations on the basic trophic parameters. The investigative period of this study took place over the years 2001, 2002, 2003. The results obtained during these investigations indicated that Lake Ohrid is in an oligotrophic state without clearly visible signs of eutrophication. The pelagic zone remains immune to the anthropogenic pressures that threatened these waters in previous decades. In Lake Ohrid it was determined that there was a highly significant, strong inverse correlation between Secchi transparency and chlorophyll a; significant, strong correlation between total phosphorus and chlorophyll a and there was a significant inverse correlation between chlorophyll a and TN:TP ratio.


Mr. Osmond Fisher, in an article in the January number of this Magazine, entitled "Convection Currents in the Earth's Interior", speaks of my views in a way that may give a false conception of what they are on the subject of overthrusts. He appears (inadvertently, no doubt) to credit me with a disbelief in the thrust-planes occurring in the North-West Highlands. I may say at once that I am one of those who admire the way in which a band of enthusiastic geologists have worked out the structure of this most difficult tract of country, and thoroughly believe in the correctness of their conclusions. The principal object of my little paper in the November number of this Magazine (1908) was to caution geologists not to push their new-born views too far in trying to account for structural difficulties by overthrusts. It must be remembered that the Moine thrust-plane has been proved to no more than 10 miles overlap, but may, of course, be much more. Incidentally, I thought the paper likely to elicit a correspondence helping the interpretation of the phenomena of overthrusts.

A thrust control valve of a liquid rocket engine plays a role to increase or decrease the thrust of an LRE by modulating the flow rate of propellant into a gas-generator. This paper deals with a flow regulator that has functions of not only modulating thrust but also maintaining constant flow rate regardless of pressure change at inlet or outlet of the flow regulator. A direct acting flow regulator was fabricated and tested for the comparison of experimental and simulation results under steady-state conditions. The drawbacks and limitations of the flow regulator were analyzed. Also the new design of a flow regulator was proposed.


ABSTRACT Certain mutations in the C-terminal region of the Escherichia coli division inhibitor protein MinC cause loss of function of the division inhibitor by making MinC more sensitive to degradation by Lon protease, implying a possible role for the C-terminal region in regulating the stability and cellular concentration of MinC.


Measurement of the noise spectrum of high performance oxide, thin‐film longitudinal and perpendicular rigid recording media have been made in order to establish the frequency dependence of the noise, the intrinsic media signal‐to‐noise ratio, and the practical recording density limit set by error rate considerations. For the oxide media tested, the noise spectrum was flat with frequency at 0.7 μV rms/100 μV rms signal indicating it was close to the particle size determined noise limit. For plated Co‐P and sputtered Co‐Re thin‐film longitudinal media the noise spectrum increases with frequency. At D70 (18 KFCI) the noise was 1.25 and 1 μV per 100 μV rms signal, respectively. For the vertical media the noise contribution came from shouldering around the fundamental frequency and was 2.5 μV/10 μV rms signal at D70 (22 KFCI) and increased with frequency. The measurements were made with both inductive and magnetoresistive heads (improved sensitivity) at 900 TPI and over a 20‐MHz bandwidth. D70 for the oxide me...


Z-Scan technology, which has the advantages of simple experimental device, convenient operation and high sensitivity, is widely used in study of nonlinear optical properties of materials. However, Z-Scan experiment is influenced by experimental environment, equipment, optical parameters and other factors, which will result in large differences in measurement data, and affect the calculation of three-order nonlinear optical polarization coefficient. Based on introducing the basic principle of laser Z-Scan technology, the paper focuses on the laser Z-Scan experiments, analysis of the factors that influence the measurement accuracy of Z-Scan, and put forward the corresponding method to improve Z-Scan experiment precision.

Adomian decomposition method is used for solving the seventh order boundary value problems. The approximate solutions of the problems are calculated in the form of a rapid convergent series and not at grid points. Two numerical examples have been considered to illustrate the efficiency and implementation of the method.


The proper handling of temporal process constraints is crucial in many application domains. However, a sophisticated support of time-aware processes is still missing in contemporary information systems. As a particular challenge, temporal constraints must be also handled for modularized processes (i.e., processes comprising subprocesses), enabling the re-use of process knowledge as well as the modular design of complex processes. This paper focuses on the representation and support of time-aware modularized processes. In particular, we present a sound and complete method to derive the duration restrictions of a time-aware (sub-)process in such a way that its temporal properties are completely specified. We then show how this characterization of a process can be utilized when re-using it as a subprocess within a modularized process.


Dance, as a form of art and physical exercise, has a very significant role for humankind. Through performance of movements accompanied by music, man expresses his emotions, thereby "radiating" energy affecting both him and the world around him. Each nation has its own distinctive customs, which are priceless. By honoring and perpetuating the traditions of their ethnicity, men and women from Serbia have used dancing as a tool for seduction and expression of love for the opposite sex. In producing this work, we conducted a study using semantic differential, where we utilized a scale of assessment of aesthetic impression (Pejic, 2007). Research was conducted on a sample of 40 (20 female and 20 male) third year students of the Faculty of Sport and Physical Education in Belgrade. The aim of the research is to reveal relationships between the sexes, as well as the aesthetic assessment of folk dances from different ethnocoreologic areas in Serbia, according to aesthetic dimensions of harmony, semantic depth, evaluation, activity, and decoration. Regardless of the influence of the folk dances from different ethnocoreologic areas of Serbia, the results of the research indicate that female participants have a higher assessment of folk dances only on the basis of harmony and evaluation. Once we looked past the role of gender of the participants and focused on the assessment of folk dances from different ethnocoreologic areas in Serbia, we noticed differences between folk dances from different ethnocoreologic areas in dimensions of harmony, semantic depth, evaluation, and activity. The interaction between the participants' gender and the folk dances from different ethnocoreologic areas was spotted solely in the dimension of semantic depth.


Most often, the electrical properties of a material are described as either "conducting" or "insulating". Copper, everyone knows, is a good conductor. It is the foundation of the electrical infrastructure of the nation. Glass, on the other hand, is an excellent insulator. But do these two words describe all the possibilities? The answer is emphatically no, and the basic subject of the research funded by this grant is aimed at fleshing out a more complete description of the electrical properties of materials. Many people are aware that there are also special materials called superconductors. A superconductor (e.g. aluminum when cooled to very low temperatures) is like a regular conductor except that it conducts electricity with no energy loss at all. Ordinary metals get hot when current flows through them; witness the toaster in your kitchen. In a superconductor something very special is going on: The electrons in the metal don't behave individually as they do in an ordinary conductor. Instead they act collectively. It is this collective aspect that makes superconductors so interesting to physicists. So now we have metals, insulators and superconductors. Is there anything else? We now know the answer is yes. In this research we examine specialmore » conducting materials, ones in which the mobile electrons are confined to move on a plane surface (as opposed to motion in all three directions). Examples of such "2D" materials include electrons confined to the interface between two otherwise insulating materials (as in the so-called "semiconductor heterostructures" used here) and the single atomic layer of carbon atoms now known as "graphene". Materials like these are not just museum curiosities; each of the billions of transistors in every smart-phone has a 2D electron system in it. In the work supported by this grant, the focus is on both collective conducting states in semiconductor heterostructures and on the conducting properties of graphene and its few-layer cousins. In particular, the exotic collective (and deeply quantum mechanical) electronic phases which develop when a large magnetic field is applied have been a major focus of effort. Significant results have been obtained from both ordinary electrical measurements and from more sophisticated thermoelectric studies of such systems. Related studies of few-layer graphenes have elucidated the transition from the two- to three-dimensional electrical properties of carbon-based conductors. Investigations like these expand our understanding of electronic materials general. While there are certainly immediate fundamental scientific pay-offs, it is also true that research of this kind ultimately leads to technological breakthroughs in the long term. By way of example, superconductivity was undoubtedly regarded as a useless novelty when it was discovered in 1911. Who could have known then that it would become crucial to the medical revolution brought about by magnetic resonance imaging decades later?« less


To overcome the huge difficulties in constructing an accurately finite element model in health diagnosis of bridge, this paper presented an improved diagnosis method via exponential weighted moving average (EWMA) control chart. Firstly the characteristic of the live-load effect of main girder strain in a bridge was analyzed as a theoretical basis of the proposed strategy. Then wavelet analysis was employed to extract the live-load effect of strain from the total measurement as sensitive feature for structural health diagnosis. Finally the EWMA control chart was designed to complete the structural health diagnosis of bridge, in which the multi-stage control limits are estimated by reliability analysis. The results from application in a concrete cable-stayed bridge show significant effectiveness of the proposed method in health diagnosis of bridge.


INTRODUCTION Hypertension is a widespread public health problem and a major risk factor. 1 It may lead to damage of heart, kidney, brain, vasculature and other organs results in premature morbidity and death. 2 Cilnidipine is a novel and unique 1,4-dihydropyridine derivatives calcium antagonist with potent inhibitory action against not only L-type but also N-type voltage-dependent calcium channels. 3 The N type voltage-dependent calcium channel plays an important role in sympathetic neurotransmission and regulates the release of norepinephrine from sympathetic nerve ending. 4 It has been reported that once daily administration of Cilnidipine resulted in a safe and more effective BP decrease in essential hypertension without excessive BP reduction or reflex tachycardia than similar administration of other dihydropyridine calcium antagonist. 5 Akira Takara 6 showed that plasma norepinephrine concentration, a sensitive marker of sympathetic nerve activity, is a significant prognostic marker of mortality in congestive heart failure patients. De Champlain 7 showed a sustained rise in blood norepinephrine levels by more than 50% after chronic therapy of Amlodipine. The inhibitory effect on the N-type ca² + channel by Cilnidipine may bestow an additional clinical advantage for the treatment of hypertension, such as suppression of reflex tachycardia. ABSTRACT Background: Hypertension is a widespread public health problem and a major risk factor. Amlodipine, a calcium channel blocker is frequently used in the treatment of hypertension. Since Amlodipine primarily L-type calcium channel blocker (CCB) and thus reduces blood pressure, it stimulates sympathetic nerve activity leading to reflex increase in heart rate. Cilnidipine, a new type of CCB which can inhibit L-type calcium channels but also N-type calcium channels. We compare the clinical effectiveness of Amlodipine and Cilnidipine on blood pressure, heart rate, proteinuria and lipid profile in hypertensive patients. Methods: The study was a prospective, randomized, open label comparison, total ninety five patients were recruited for study in which 45 patients received 5-10mg Amlodipine and other 55 patients of same age groups received 10-20mg Cilnidipine. 15 patients in Amlodipine group and 18 patients in Cilnidipine group were diabetic, whereas 12 and 14 patients were proteinuric in Amlodipine and Cilnidipine group respectively. Results: Both the groups were well matched in term of age, weight, clinical findings and laboratory values. Both the drug significantly reduced both systolic (SBP) and diastolic blood pressure (DSP). In the Amlodipine group the pulse rate (PR) after treatment tended to be higher than those before treatment. In the Cilnidipine group …


We automated a two‐step kinetic procedure for determining serum CK‐MM isoform ratio using an immunoinhibition method. By measuring the total CK activity and the residual CK activity (serum CK‐MM isoform) remaining after the inhibition by tissue CK‐MM isoform specific monoclonal antibody reagent (CK‐M01) the CKMM isoform ratio is calculated using the difference between total CK and residual CK activities divided by the residual CK activity.

Sexual dysfunction in men has been found to be highly prevalent and have a negative effect on quality of life. Lower urinary tract symptoms (LUTS) are prevalent in men, and their prevalence and severity increase with age. Overactive bladder (OAB) is the symptoms complex that include urgency, with or without urgency urinary incontinence, usually with increased daytime frequency or nocturia. Voiding symptoms, e.g. weak or slow stream, intermittency, hesitancy, straining and terminal dribble, and postmicturition symptoms, e. g. incomplete emptying and post-micturition dribble, can also co-occur with OAB. Symptoms associated with OAB negatively affect the social, psychological, occupational, physical and sexual lives of both men and women.

The diagnostic machinery monitoring system presented in this paper coordinates the acquisition of vibration and speed estimates for an electric machine. It functions even when the machine is "off" or spinning down. This effectively turns the machine into its own mechanical network analyzer. Data from this system can be used to correlate electrical and mechanical data in order to distinguish a variety of pathologies in the machine and its mechanical mounts. The entire sensor system powers itself from surrounding magnetic fields, requiring no ohmic contact or special power wiring. The system presented in this paper presents a unique approach for fusing data from multiple sensors to create a coordinated picture of machine operation on a self-powered platform.

The assigned examination approach has been utilized in the exploration to dissect the advantages and disadvantages of AI and the result of the examination is certain. The chatbots can be reserved to test the utilization of information, aptitude advancement, and data maintenance in a basic, consistent, and non-meddlesome way. It can be utilized to gamify the learning experience by adopting dynamic levels and ceaselessly captivating workers with pioneer sheets and updates on their advancement. HR chatbots can likewise give quick criticism on the viability of preparing modules, along these lines, helping in ideal recognizing what's working and what isn't. This assists the managers with comprehension and examines the conduct of their representatives. Detailed applicable learning strategies are considered for better requirements.


The dynamic spectra are calculated for two possible mechanisms of formation of ''modulation lines'' in the dynamic spectrum of Jovian decameter radio emission: 1) the Cotton--Mouton effect in the Jovian ionosphere and magnetosphere and 2) frequency modulation of the intensity in the source; the characteristic signs distinguishing spectra with bands due to the Cotton--Mouton effect from spectra in which the bands appear as a result of the action of the second mechanism are indicated. The conditions for the development of the Cotton--Mouton effect and of modulation of the frequency spectrum in the source on Jupiter are discussed. Electron concentrations of 10/sup 3/--10/sup 4/ el/cm/sup 3/ are sufficient to explain the ''modulation lines'' by the Cotton--Mouton effect in the Jovian ionosphere or lower magnetosphere. The difficulties in explaining (by analogy with the zebra structure in solar radio emission) modulation of the frequency spectrum in the source by the intense excitation of plasma waves in layers where the condition for double plasma resonance at harmonics of the electron or ion gyrofrequency is satisfied are pointed out.


By definition, "chemical reactions" should involve the breaking and the forming of bonds between atoms and are not usually described by using molecular dynamics (MD) simulations employing classical force fields. Here, the major huddle is that the change in the chemical bonds can only be understood as a pure quantum-mechanical (QM) effect, leading to a change in the fundamental equation of motion for MD from one described by Newtonian mechanics to one described by quantum mechanics. In this article, we introduce recent approaches, reactive force field (ReaxFF) and electron force field (eFF), that were developed to overcome the limitations originating from the extremely heavy computational cost to numerically solve the timedependent QM equation. These new efforts allow largescale MD simulations by solving classical (or classical-like) equations of motions where QM effects are essentially approximated by introducing the concept of bond order (ReaxFF) or by describing the electrons with breathing Gaussian wavepackets (eFF). We then discuss how these new simulation methodologies can be applied to investigate the complicated dynamical problems in which chemical reactions and/or phase transitions induced by electronic excitations are strongly involved.


Semantic segmentation has been a fundamental task in interpreting remote sensing imagery (RSI) for various downstream applications. Due to the high intra-class variants and inter-class similarities, inflexibly transferring natural image-specific networks to RSI is inadvisable. To enhance the distinguishability of learnt representations, attention modules were developed and applied to RSI, resulting in satisfactory improvements. However, these designs capture contextual information by equally handling all the pixels regardless of whether they around edges. Therefore, blurry boundaries are generated, rising high uncertainties in classifying vast adjacent pixels. Hereby, we propose an edge distribution attention module (EDA) to highlight the edge distributions of leant feature maps in a self-attentive fashion. In this module, we first formulate and model column-wise and row-wise edge attention maps based on covariance matrix analysis. Furthermore, a hybrid attention module (HAM) that emphasizes the edge distributions and position-wise dependencies is devised combing with non-local block. Consequently, a conceptually end-to-end neural network, termed as EDENet, is proposed to integrate HAM hierarchically for the detailed strengthening of multi-level representations. EDENet implicitly learns representative and discriminative features, providing available and reasonable cues for dense prediction. The experimental results evaluated on ISPRS Vaihingen, Potsdam and DeepGlobe datasets show the efficacy and superiority to the state-of-the-art methods on overall accuracy (OA) and mean intersection over union (mIoU). In addition, the ablation study further validates the effects of EDA.


Objectives:  To audit past practice of intravenous (i.v.) fluid prescribing and electrolyte monitoring, prior to the publication of guidelines by the National Patient Safety Agency (NPSA, Ref. NPSA/2007/22) in March 2007, highlighting areas of discrepancy, in a specialist children's hospital.


The purpose of this paper is the exploration of students' preferred social media (SM) tools for receiving information about their academic library. The authors administered a questionnaire at their prospective institutions: the College of Staten Island (CSI), City University of New York, USA and the University of Western Ontario (UWO) in London, Ontario, Canada. The authors examine students' preferences for various SM tools, and analyzed the types of information students expect from the library's SM accounts. The authors argue that the library's SM postings should be curated based on market research that provides a better understanding of the target audience.,The authors explore the SM preferences of students at their prospective institutions. The authors examine the SM channels students visit and the types of SM content they wish to seek out. The authors ran the authors' study from September 1 through December 31, 2016. The authors used convenience sampling and a printed questionnaire to collect data from students in information literacy instruction sessions (n=633 at CSI, n=602 at UWO).,The authors found that more students (at both institutions) used Facebook and YouTube, as compared with other SM platforms. If they viewed their library's SM accounts, students from both institutions preferred to read about news and current events, followed by announcements about new library services.,The authors illustrate that conducting market research helps SM managers understand their target audience. Market research is the key to successful SM management. It also helps in the development of a marketing plan and provides insights on students' preferences regarding SM content.,This study compares students' SM preferences across two academic institutions from two countries, the USA and Canada. The authors wished to investigate the similarities and differences among these students' preferences.


The main objective of this thesis is to study the market which is currently served by "Bodega Estefania" to know the perception of customers about the brand, and also study the supermarket market to find opportunities that allow the business to have positive results to implement a plan to reposition the brand of the company and generate a differentiation based on the sale of semi-prepared foods. To analyze the feasibility of implementing this improvement plan, a comprehensive analysis of the company was conducted to find the current strengths and weaknesses. Then a macroeconomic study analyzing the national economy, industry, political, social, environmental and legal factors was performed. Later a market study including surveys, focus groups and interviews with experts was done; this helped identify strategies. Finally a financial analysis to demonstrate the profitability of this plan getting a NPV of $ 65,975.21 and an IRR of 56 % in the financed and expected scenario was developed. The idea of improving the business has been simmering for 5 years. The owners want to achieve the creation of a successful business model that is sustainable in the long term, taking into account the expansion of large supermarket chains.


Abstract A particle adhesion method for the determination of the isoelectric point (iep) of planar oxide surfaces in aqueous media is described. The experiment consists in measuring the rate of deposition of latex particles as a function of pH. We have measured the iep of fused silica, soda-lime silicate glass and thin films of different metal oxides: tin, aluminum, iridium and tungsten. We find our results in good agreement with data from the literature obtained with other experimental techniques.


MLP 00-III-5-1 is a distal end of a right tibiotarsus belonging to a fossil penguin. It comes from the Cerro Aguila Conglomerate (53°50'14.85"S, 67°47'29.78"W) near Rio Grande City, Tierra del Fuego, Argentina. These beds overly sediments referable to the Cabo Pena Formation, probably similar in age to that of the Middle Miocene Carmen Silva Formation. The fossil described here is the only fossil penguin from this unit and represents the southernmost record of a Neogene penguin in South America.


Objective: The cause of chronic critical lower limb ischemia is
often the combination of diabetic angiopathy and
atherosclerotic disease of crural arteries. Foot gangrene is
the terminal stage in this cases and the pedal bypass grafting
is often the only method of limb salvage. Methods: In 2000 to
2004, 64 pedal bypasses were performed in 63 patients with
chronic critical lower limb ischemia. Fifty-six (87.5 %)
patients had gangrene or ischemic ulcer, 44 (69.8 %) had
diabetes. In some of the patients (17.2 %), previous
percutaneous transluminal angioplasty of the crural arteries
had failed. Preoperative angiographic findings were
unsatisfactory in the majority of the patients; the pedal arch
was not visualized in 40 (62.5 %) limbs. The cumulative primary
and secondary graft patency rates and limb-salvage rate were
assessed by Kaplan-Meiers survival analysis. Fishers exact test
was used to investigate whether the absence of the pedal arch
on preoperative arteriograms was related to an increased risk
of graft occlusion. Results: During 60 months of follow-up, 14
grafts (22 %) failed. Early thrombectomy resulting in long-term
graft patency salvaged 8 limbs. One limb with graft occlusion,
occurring after foot ulcer had healed, was also salvaged.
However, one amputation had to be performed despite a patent
graft. The perioperative mortality rate was 3.2 %. Cumulative
primary and secondary graft patency rates and limb-salvage
rates at 60 months were 75 %, 79 % and 82 %, respectively. The
14 occluded grafts were recorded in nine limbs (22.5 %) that,
on preoperative arteriograms, had no visible pedal arch (n=40)
and in five limbs (20.8 %) with a visible pedal arch (n=24).
The difference in the risk of graft occlusion between these two
groups was not significant (Fishers exact test, P=1.000).
Conclusions: Pedal bypass grafting is a safe method with good
long-term outcomes. Since the absence of the pedal arch on
preoperative arteriograms does not increase the risk of graft
occlusion, unsatisfactory preoperative angiographic findings
need not be taken as a contraindication to pedal vascular
reconstruction.


The water environment of Lake Dianchi in Yunnan province is threatened by eutrophication, which leads to the decrease of dissolved oxygen in water. Meanwhile, as the index reflecting the pollution of organic and inorganic oxidizable substances in water, permanganate index is also affected. China has been developing the automatic monitoring system for a series of water quality factors, such as dissolved oxygen and permanganate index. Additionally, the monitoring and prediction of ammonia-nitrogen, one of the water eutrophication sources, are also important. This study analyzed the water quality factor data in Lake Dianchi from 2015 to 2018 and implemented the prediction based on the Long Short-Term Memory neural network algorithm. It is found that the water quality of Lake Dianchi will be in a relatively ideal state in the future, but it cannot be improved further by itself. The Kunming government should implement more targeted improvement measures according to the characteristics of water quality factors, such as the seasonality of Lake Dianchi. Those measures will improve the ecological service quality of Lake Dianchi effectively, ensure the daily water safety of people in Kunming, and bring more economic values to the city.


Nodular fasciitis (NF) is a benign, self‐limited, fibroblastic/myofibroblastic proliferation that is diagnostically challenging, often mimicking a malignant process due to its rapid growth clinically and its high cellularity, mitotic activity, and variable/nonspecific cytomorphologic findings. Herein, the authors report what to their knowledge is the largest and first multi‐institutional study of the cytomorphologic characteristics of NF by fine‐needle aspiration (FNA).


ABSTRACT Novel detrimental functions of senescent cells have been recently uncovered in the context of cancer development and progression, which they mainly exert through the secretion of several pro-tumorigenic factors. Here we discuss how cellular senescence and its secretory phenotype can be involved in the widely unexplored phenomenon of paracrine tumorigenesis.


Books which deal broadly with some historical age or epoch generally fall mto one of two categones There are, first of all, works of analysis and interpretation which advance some overarching thesis, some sweeping generalization, by which the discrete events of the period may be better understood. E.J. Hobsbawm's The Age of Revolution, 1789-1848 and The Age of Capital, 1848-1875 or Arno J. Mayer's The Persistence of the Old Regime are good examples. The danger in this approach is reductiomsm and one-sidedness; it tends to depreciate or ignore developments which do not fit into the grand design. Then there are the works which can best be described


This paper reports the findings of a comparative case-study project which evaluated the development of nursing research capacity in two academic schools in the United Kingdom. The research compared the approaches used, explored the experiences of staff during the implementation process, and identified the outcomes which were achieved. The methods employed were in-depth interviews, focus groups and documentary analysis. A literature review was undertaken to inform the design and conduct of the study (Segrott et al., 2006). The project's findings are divided into five sections. We begin by discussing the strategies implemented by the two schools, and their overall success. We then examine the wider development of a research culture, explore the problems and challenges experienced, and consider the management and organisation of capacity building. The final theme concerns the role played by the schools' wider institutional and political contexts. The paper explores the relative strengths of inclusive and exclusive approaches to staff development, and the importance of integrated academic leadership and effective management. The study highlights the need for academic schools to forge strong connections between experienced researchers and novices, as well as between teaching and research activities.


The relationships between the extent and quality of paved road infrastructure and national per capita income are investigated. A number of selected variables are incorporated in the relationship involving a study of 98 countries. The analyses include cross-sectional and time series methods, with data going back to 1950. Consistent and significant associations between economic development, in terms of per capita gross national product, and paved road infrastructure, on a per capita basis, are demonstrated. The data show that the per capita stock of paved road infrastructure in high-income national economies is dramatically greater than those in middle- and low-income economies. For example, the average density of paved roads (km/1 million people) varies from 170 in low-income economies to 1,660 in middle-income economies to 10,110 in high-income economies. In other words the average density of paved roads in high-income economies is nearly 60 times that in low-income economies. Although it is less definitive, road condition also appears to be associated with economic development. The average density of paved roads in good condition ranges from 40 km/1 million people in low-income economies to 470 in middle-income economies to 8,550 in high-income economies. The information and relationships presented can be used as indicators of weakness or strength in national road infrastructure stock or asset. An initial analysis of Canada's relative ranking is provided. Causality (that is, does an increase in road stock lead to growth, or vice versa?) is also briefly explored.


Research on rubber fatigue properties is of great significance for improving the durability of rubber products. Natural rubber is widely used in rubber products, it is very important to study the effect of temperature on its fatigue properties. Here, tensile fatigue tests of natural rubber have been carried out under different temperatures and strains for studying the influence of temperature and strain on the fatigue life. Results indicate that fatigue life decreases when test temperature increases, and it decreases obviously when temperature is higher than 75 °C; with increasement of temperature, tensile strength decreases, and the elongation at break increases; the fatigue life decreases with the increasement of strain, and the decreasement of fatigue life is more remarkable under small strain.


Abstract Conventional glued-laminated timber (glulam) was not permitted to use to a wooden building in the fire preventive district since the amendments of the Building Standards. We already developed a one-hour fire-proof glulam made of Japanese cedar. We also succeeded to give one-hour fire performance to cross laminated timber by the same concept. The both structures are composed of three parts which are load-bearing part, fire-die-out part and surface part. The fire-die-out part is made of lamina incised by CO2 laser and impregnated the fire retardant evenly. As the handling of CO2 laser is not so easy for glulam manufacturer, we felt a growing need for drill incising technology. Therefore, we made pinholes of some diameters up to 2.5 mm to lamina of Japanese cedar, by a drill and investigated differences of hole position on two sides of the lamina. The maximum off-center for length and width directions was 1.8 and 3.3 mm, respectively. These off-centers are 2.3% and 41% of distances between neighboring hole on incising patterns. As the results of impregnating performance and fire-resistive performance of lamina incised by drill, significant differences were not recognized between drill incising and laser incising.


This study investigated the issues and management of construction cost overruns in a public university in Ghana. Specifically, the study answered the following research questions: (1) What types of project experience construction cost overrun? (2) What are the causes of project construction cost overruns? (3) How are project construction cost overruns managed? The study used the qualitative research approach. Documentary reviews and participant observation were the research methods employed for the data collection. The study showed that all types of construction project irrespective of the source of funding (i.e., internally generated funded, Ghana Education Trust Funded and externally funded project) experienced cost overruns. Also, it was established that contractors, location of the project, project consultants and funders were responsible for construction cost overrun in the university. In terms of the management of projects with cost overrun, they were based on the circumstances surrounding each project.The study recommendsthat due diligence should be done before awarding construction project contracts to avoid contractual stalemates in the future. Also, the income statement of contractors should be thoroughly analyzed to ensure they are not concurrently executing numerous projects and have the financial capacity to execute the project. Other resources like human resources and machinery should also be thoroughly analyzed to ensure their adequacy. Additionally, project consultants should ensure that their roles in projects that have been awarded for construction are effectively and efficiently carried out.


Executive Information Systems (EIS) began to become popular in Spain in the 1990s. This chapter offers a primary descriptive study of EIS in Spain, bearing in mind two aims: to study the EIS usage in Spain and undertake a comparative analysis with reference to previous research. In this way, starting from the recognized EIS development framework of Watson, Rainer and Koh (1991), the authors focus on the structural perspective of the EIS elements and the development process. The study is based on a survey involving 70 organizations. The results show both parallelisms with preceding studies and new contributions to the current knowledge in the EIS field. Finally, the chapter identifies future trends in the executive information system concept. INTRODUCTION Ten years ago, Watson, Rainer, and Koh (1991) set a landmark in the study of executive information systems (EIS) practices. Their work described a useful framework for EIS development which encompasses three elements: a structural This chapter appears in the book, Decision Making Support System: Achievements, Trends and Challenges, edited by Manuel Mora, Guiseppi Forgionne and Jatinder Gupta.

CONSTITUTION: An apparatus for recycling lubricating oil includes a moisture absorbing cartridge(140). A superabsorbent polymer(SAP)(142) is installed at the boundary of a polyester mesh(143) in the cartridge. Moisture is extracted from the lubricating oil or other fluid and is absorbed in the SAP. The SAP with the moisture is gelated. A polypropylene absorbing layer(144) is installed at the external side of the polyester mesh and remains moisture at the external side of the absorbing layer.


The use of low friction wear resistant coatings for machine components is rapidly increasing. These components may operate in any lubrication regime, and less frequently even un lubricated. When run unlubricated it is easy to see the beneficial effect of a low friction coating. However, it has frequently been shown that the coating may also be very beneficial under boundary and mixed lubrication conditions. The present digest briefly presents a few interesting aspects of the use of low friction coatings in lubricated contact illustrated by selected experimental results.

Abstract The basic objective of the research is to determine whether the education that prospective teachers at different fields receive is related to their levels of problem solving skills and self-confidence. Within the mentioned framework, the prospective teachers' problem solving and self confidence levels have been examined under several variables. The research sampling has been formed by 162 students who are currently studying for their bachelor's degree in Marmara University, Ataturk Faculty of Education (n = 92 Music, n = 70 PCG). 70.7% of Music Teaching Department students are females, 29.3% are males and 69.6% is between 18-22 ages. 52.9% of Psychological Counseling and Guidance students are females, 47.1% is males and 97.1 % of them consist of the students within this age group. The Problem Solving Inventory developed by Heppner and Peterson (1982) and the Piers-Harris Self-Concept Scale adapted to Turkish by Catakli and Oner and Individual Information Form has been utilized in the research. The data of the research have been analyzed by, t-test, Kruskal Wallis-H, and Mann Whitney U tests. The findings have introduced that there are statistical differences in the aspect of some sub-dimensional values for both scales (Avoidance: t=-2.330; p Key Words Education, Problem Solving Skills, Self-Confidence. It is widely known that many factors affect learning. Some of those are interest, motivation, attitudes, problem-solving skills, self confidence, and self sufficiency. Since there is a positive relationship between successes, self-confidence and motivation, having a higher levels of mentioned capabilities increases success and having a lower levels of those diminishes success. This is because when individuals have selfconfidence, they feel better within the process of learning and higher level of learning is accomplished. The basic opinion is that individuals having higher levels of self-confidence are more successful in solving problems that they confront (Owens, 2001). This situation emphasizes the necessity for defining self-confidence which is assumed to have a great effect on learning. Self confidence is answering the question; "How the others are seeing me?" Our perception is always connecting with the others (Baltas, 2002). Nowadays, research studies show that self-confidence and success are related (Daniel, 2006). Particularly, Fitch (1970) pointed out the relationship between self-confidence and success. In addition, self-confidence is one of the most important factors for motivation and future success. In another research, Hair (2003) found that positive selfconfidence affects academic success positively. In order to maintain efficient teaching in all branches of education, there are several important factors such as teachers' attitudes, perceptions and behaviors, students' interests, talents and attitudes, and educational methods used. All these factors complete each other within the process of education. Besides, new approaches and the use of new methods are compulsory in educational process in order to maintain active participation of students and enrich the process of education. Problem-solving methods must take place among the methods used by the teachers in the classroom (Cakmak, 2003). Problem-solving is selecting and using the efficient and useful tools and actions among all facilities to reach the desired targets (Demirel, 2000). The purpose of the educator using this method is to direct students to scientific thinking and sufficient problem-solving skills. …


Several assays are available to measure human ghrelin (h-GHS), but the comparability of results among assays is unknown. As an addition to previous investigations concerning the stability of h-GHS (1), it was our objective to compare the two most commonly used commercial h-GHS RIAs, focusing on side-by-side determinations, recoveries, and assay imprecision.

The assays were purchased from Phoenix Pharmaceuticals (cat. no. RK-031-30) and Linco Research (cat. no. GHRT-89HK). Samples were stored at −80 °C and assayed as recommended by the manufacturers.

For side-by-side comparisons, we used anonymized surplus sera (n = 151) from clinical studies of lean and obese individuals [mean body mass index (BMI), 26 kg/m2; range, 17–39 kg/m2]. Separate side-by-side comparisons were performed with 68 samples from two individuals (34/profile; BMI, 19.5 kg/m2) taken at 20-min intervals to evaluate the suitability of the assays for determining intraindividual changes. All participants gave informed consent.

For recovery and imprecision studies, serum was collected from four males (27–33 years of age; no drug use; normal blood pressure; BMI, 22–24 kg/m2). Assay calibrators were added to achieve added concentrations of 100, 200, 400, or 800 ng/L. Each was measured 20 times. Recovery was calculated by subtracting the basal value of …


A numerical study was made of the confinement of a uniform magnetic field by a warm plasma with a net velocity parallel to the confined field. Parker's assumptions of a vanishing electric field and vanishing trapped-particle currents and pressures were adopted. For a given proton temperature equilibriums were found whenever the electron temperature exceeded a certain critical value. This result is in qualitative agreement with an estimate presented by Parker, but it is in direct conflict with Lerche's nonexistence proof. A crucial error in that proof is identified. The properties of the equilibrium solutions are discussed. Finally, the equilibrium confinement with the incident streaming plasma tangential to the magnetopause but perpendicular to the confined field is treated. It is concluded that in the geomagnetic equatorial plane equilibriums of Parker's type are possible on the morning side but not on the afternoon side of the magnetosphere.


The thermal degradation kinetics of poly(3-hydroxybutyrate) (PHB) and poly(3-hydroxybutyrate-co-3-hydroxyvalerate) [poly(HB–HV)] under nitrogen was studied by thermogravimetry (TG). The results show that the thermal degradation temperatures (To, Tp, and Tf) increased with an increasing heating rate (B). Poly(HB–HV) was thermally more stable than PHB because its thermal degradation temperatures, To(0), Tp(0), and Tf(0)—determined by extrapolation to B = 0°C/min—increased by 13°C–15°C over those of PHB. The thermal degradation mechanism of PHB and poly(HB–HV) under nitrogen were investigated with TG–FTIR and Py–GC/MS. The results show that the degradation products of PHB are mainly propene, 2-butenoic acid, propenyl-2-butenoate and butyric-2-butenoate; whereas, those of poly(HB–HV) are mainly propene, 2-butenoic acid, 2-pentenoic acid, propenyl-2-butenoate, propenyl-2-pentenoate, butyric-2-butenoate, pentanoic-2-pentenoate, and CO2. The degradation is probably initiated from the chain scission of the ester linkage. © 2003 Wiley Periodicals, Inc. J Appl Polym Sci 89: 1530–1536, 2003


Audit Delay or in some studies referred to as audit reporting lag is the time difference between the end of the fiscal year (date of closing the book) with the date of issuance of the audit report (independent auditor's report). This study aims to provide empirical evidence regarding the influence of company size, company age, number of audit committees and the proportion of public ownership on the number of audit delay days. The research sample was chosen based on the purposive sampling method in all companies except banks and insurance listed on the Indonesia stock exchange. With the observation period from 2014 to 2018. The samples obtained were 112 companies with 560 observations. The results indicate that company size does not significantly influence the number of audit delay days. This study also found that the age of the company has a significant effect on the number of days of audit delay. Meanwhile, this study found that the number of audit committees does not significantly influence the number of audit delay days.


A standard configuration composed of RC and operational amplifiers is used for the realization of any second-order voltage transfer function. The approach blends well into the hybrid microelectronics field and promises absolute stability and very low sensitivity.


High-grade glioblastoma (GBM) is a highly heterogeneous, malignant cancer with no cure to date. A sex-biased incidence and therapeutic response is reported (1) for GBM with a male to female incidence ratio of 1.6:1 and female patients having a 4-6 month survival advantage (2) compared to male patients. In our current work, we sought to determine the molecular basis for the sex-bias in incidence and therapeutic response using an isogenic murine model of GBM with dual loss of neurofibromin 1 (NF1) and P53 (DNP53) in astrocytes. Our model yielded GBM from the murine astrocytes in a sex-biased manner, with male GBM cells exhibiting a highly significant proliferative, migratory, in-vivo tumorigenicity, stem-cell enrichment rate and therapeutic resistance compared to female GBM cells. Using transposon calling cards, we mapped Brd4 enhancer usage across the genome in male, compared to female GBM cells and identified key transcription factors that differentially enriched at male-biased, compared to female-biased Brd4 bound enhancers. Interestingly, female-biased Brd4-bound enhancers were enriched for transcription factors with tumor suppressor roles including P53 and SMAD4, whereas male-biased Brd4-bound enhancers were enriched for transcription factors with oncogenic roles, including Oct4, MYC and KLF5. Genetic or chemical silencing of KLF5 reduced the tumorigenic potential in male GBM with rates of cellular proliferation, survival, migration and stem-cell frequency significantly reduced to levels that resemble female GBM. Using transposon calling cards, we mapped KLF5 genomic localization in male and female GBM cells and identified significant peaks that affiliated with differentially expressed genes between the sexes. Interestingly, genes induced by KLF5 in the male cells were affiliated with poor survival in patients with various cancers, whereas those induced by KLF5 in the female cells were affiliated with favorable prognosis. This signifies the need to explore molecular mechanisms by which KLF5 drives these sex differences in GBM.


Benzo[b]thiophen-3-carboxylic acid 1,1-dioxide is shown to undergo dimerization to a cyclobutane under the influence both of ultraviolet light and of heat, whereas the corresponding methyl ester is dimerized only by ultraviolet light. The dimer is shown to be of the 'head-to- head' type, with trans stereochemistry about the cyclobutane ring.


John Steigauf waS fighting a losing battle with type 2 diabetes. Diet, exercise, and medication: none of it was working, he felt exhausted all the time, and friends said he no longer looked like himself. Still, Steigauf put off what he really needed—insulin injections— for fear he would lose his job. when Steigauf, then 47, finally went on insulin in 2004, his health improved but his fear proved well founded: he was deemed unfit to keep his position of 14 years with united Parcel Service. it was more than a decade after the passage of the americans with Disabilities act, landmark civil rights legislation that was supposed to protect americans with disabilities, including those with chronic diseases, from workplace discrimination. But a string of Supreme Court decisions and lower court rulings had undermined the law's effectiveness, leaving Steigauf and others at the mercy of unsympathetic or uninformed employers. a broad disability rights coalition, including advocates from the american Diabetes association, knew only one strategy could restore what the courts had taken away: pushing a reform of the 1990 law through Congress and the


Expanding financing channels is important for dealing with the financing difficulty,the bottle-neck for the development of small and middle-sized enterprises. Joint guaranty loan(an innovative financing product),while helping small-sized enterprises financing,takes new legal risks. Based on the analysis of the current situation and characteristics of credit financing for small and middle-sized enterprises and the reasons for difficult financing,this paper exposes the connotation of joint guaranty loan and the value orientation and questions of the law,and proposes legal advice on innovative credit financing for small and middle-sized enterprises.


This research article has three objectives, namely: (1) to study the causes and effects of anger in Buddhism in general, (2) to study the methods of extinguishing anger inBuddhism, and (3) to study the benefi ts of extinguishing anger in Buddhism.During this research, it was found that there are many causes and effects of angeraccording to Buddhism. Concerning the causes of anger, it is mostly caused by unwholesome roots (akusala mūla), worldly conditions (lokadhamma), defi lements (kilesa), craving(taṇhā), etc. Moreover, concerning the effects of anger, anger directly affects one's selfand others.Furthermore, the researcher found that there are two benefi ts of extinguishing angerin Buddhism, those are benefi ts for oneself and benefi ts for others. In addition, there aresome more benefi ts, which are: one not destroys one's life, is shameful to do evil, knowsthe advantages of Dhamma, and experiences a cool mind all the time. On the other hand,the benefits of extinguishing anger for others are: one respects and is kind to all beings,lives together with others in peace and harmony.The paper also discusses the meaning and the problems of anger in Buddhism ingeneral and discusses the methods of extinguishing anger in Buddhism. In the research, itwas found that there are several methods of extinguishing anger in Buddhism. Particularlyimportant is the reflection method, which is the reflection on the Buddha's teachings, andreflection on many different objectives in order to extinguish anger.


WD repeat domain 3 (WDR3) is involved in tumor growth and proliferation, but its role in the pathological mechanism of prostate cancer (PCa) is still unclear.


The image of China in Hong Kong-Macau literature coheres the countrymen' love to China and interprets the particular culture identity of Hong Kong-Macau literature.As the two local literature which are intimate and also independent in Chinese-Language literature,Hong Kong literature and Macau literature obviously have their own tactics to imagine China and construct the image of China.This paper attempts to compare the images of China in Hong Kong literature and Macau literature from the aspects on politics,economics and ecololgy,in order to confirm the interdependent logical relationship among literary field and other social fields,and to exposit the discourse differences and potential factors of imaging China between the fields of Hong Kong and Macau literature.


In this issue is presented a study by KL Leung and colleagues,1 a post-hoc analysis of a dataset comprising the medication profiles of a cohort of community-dwelling older adults in Hong Kong collected during 2016, initially acquired during a study investigating the relationship between diet and the prevalence of atrial fibrillation.2 A total of 1665 Cantonese-speaking older adults (aged ≥65 years) attending recreational community centres in Hong Kong were recruited, excluding any with terminal health conditions or significant cognitive impairment. The authors described an association between the use of beta-blockers in their cohort (particularly atenolol) and the prevalence of obesity, evident in the hypertensive cohort (hypertension being the likely dominant reason for prescription of beta-blockers). It has been known for some time the use of beta-blockers is associated with mild-to-moderate weight gain, of the order of 1 to 2 kg, although the mechanisms have not been fully established.3 This has not been investigated in an elderly communitydwelling Chinese population in the past and this publication extends our knowledge. Being retrospective it can never, of course, prove cause and effect and hence we have a chicken and egg argument. As the authors rightly point out we cannot differentiate between beta-blockers causing obesity, versus obesity leading to a preferential use of beta-blockers, which might itself be through multiple mechanisms. In addition, obese individuals have larger arms and may, by conventional blood pressure (BP) measurement (if an extra-large arm cuff is not used), lead to falsely elevated BP levels, meaning more antihypertensive medication is prescribed. I have added an allusion to a farmer to the usual chicken and egg argument in the title, for there is also the possibility that the supervising physician specifically chose beta-blockers as the class of antihypertensive agent of first choice because the patient was overweight; the authors point this out, and some guidelines have recommended betablockers for obese hypertensive patients. Should these results concern us? As is so common in such matters, it is difficult to say for certain. One scenario is, of course, that the betablockers have been prescribed most likely in an Hong Kong Med J 2020;26:6–7 https://doi.org/10.12809/hkmj205093


While the morphology and specific genetic translocations vary among the different types of translocation sarcomas, translocation sarcomas are known to share one common feature: they often appear bland and monotonous, and this appearance may distract from their otherwise malignant nature. While this understanding is well established in many surgical pathology reports, the cytomorphological features have only been described in smaller case series and individual case reports. In this study, the authors describe the cytomorphological features of 147 translocation sarcomas as seen on fine needle aspiration at our institution over a 25-year period.


Extraskeletal osteosarcoma (EOO) is a rare malignant mesenchymal tumor that grows in soft tissue without attaching to skeleton. Extraskeletal osteosarcoma arising in the ureter is extremely rare and only 3 cases have been reported in detail to date. In our study, an 81-year-old man presented with a 1-month history of painless naked hematuria. Computed tomography (CT) scan revealed that there was a solid tumor in the left distal ureter. Subsequently, radical resection was performed. Immunohistochemical staining of specimens showed that the tumor cells were positive for vimentin and Ki-67, but negative for other specific markers. The findings favored the primary ureteral osteosarcoma. Adjuvant radiotherapy was recommended but was refused. Four months later, regular clinical follow-up revealed no evidence of recurrence. The aim of present study is to report an additional case of ureteral osteosarcoma, focusing on the characteristics, including pathogenesis, diagnosis, treatment and outcomes.

The view of normal distribution of examination performance is not always established,while the distribution of examination performance is negative skewness distribution in the most situations.Based on the current teaching requirements,a new standard distribution of examination performance was constructed with cubic Hermite splines and B-spline,and some practice cases were analyzed.Finally,some suggestions were provided.


Positron emission tomography (PET) combined with magnetic resonance (MR) is a rapidly expanding imaging modality. For this application, the availability of radiotracers labelled with positron emitters is a basic requirement. These short-lived neutron deficient positron emitters are produced at a cyclotron. In a cyclotron, charged particles are accelerated up to energies enabling to overcome Coulomb repulsion and induce nuclear reactions. The beam is extracted to target systems containing stable isotopes. Due to the bombardment, these stable isotopes are converted via nuclear reactions into radionuclides. The positron emitters are subsequently used for radiolabelling molecules to obtain radiotracers for various applications. Usually radiosyntheses are carried out in automated synthesis modules. The relatively short physical half-life of the positron emitters in use requires fast and efficient radiolabelling strategies that have been optimised for the most common radiopharmaceuticals in order to facilitate robust tracer production in sufficient activity amounts. Beside the PET alone approach, emerging methods deal with simultaneous PET-MR imaging to combine the high sensitivity of PET with the high resolution of MR. One possibility to exploit the synergy of both techniques is the combination of clinically established paramagnetic contrast agents and radiopharmaceuticals. This method was studied in several preclinical and clinical studies. A much more elegant possibility is the introduction of both modalities in one single, bimodal contrast and positron-emitting probe. Thus far, this technique was only tested in preclinical set-ups.


Dudgeon, Dan E., ATR Performance Modeling and Estimation, Digital Signal Processing10 (2000), 269?285.This paper provides an overview of approaches and issues in modeling the performance of automatic target recognition (ATR) systems. The need to understand ATR performance capability is important under circumstances in which significant testing is not possible, for example, because of the amount of data required to be collected to accurately assess performance and its associated cost or because of denied targets and ground environments. One would like to have a "theory" to extrapolate ATR performance from a well-characterized set of data to situations likely to be confronted in real military operations. Unfortunately no such theory exists, in part because of the difficulty of characterizing and representing in a computational model the inherent variability of target signatures and the backgrounds in which they are embedded.


First, we recall that geothermal heat melted basal ice of the thick Laurentide Ice Sheet to produce a warm-based glacier in places and sometimes abundant meltwater. As well, supraglacial meltwater probably reached the ice bed (Zwally et al. 2002). The meltwater so produced was under thick ice and high pressure and could have attained high velocities which enabled it to entrain sand to even the coarsest clasts in till to become a turbulent highly erosive subglacial flow when released, possibly when a seal to the ground in the marginal ice zone was breached.


The electrical power companies' load consists of several kinds of customers, for example, agricultural, building, industrial, etc. Agricultural and industrial energy consumption is based on highly inductive loads, and it leads to the electricity shutdown because of highly inductive loads effect large spikes to the power curve. These spikes show their irregular disturbance in the electric power system due to shutdown and start-up of these large loads. It is considered irregular as well as a tough job to forecast the load with the existence of such kinds of spikes. Further, the heterogeneous and multi-source load consumption characteristics necessitate the integration of evolutionary models and the ensemble techniques render better robustness and forecast accuracy. For this purpose, we proposed the novel deep regression and stump tree-based ensembles models (DRTSEM) for accurate load planning and management with the use of highly inductive load data, buildings loads, etc. The hyperparameters e.g., network weight decay, network learning rate, the total number of hidden layers and momentum of the DRTSEM is optimized by using the deep regression and stump tree-based algorithms. For forecasting analysis, two different climate zones and seven model's input model parameter selection (MPS) with new sets of the data samples are used. The forecasting performance is testified with the generalization network error and resubstituting loss, 10-fold cross-validated mean square error, four performance evaluation statistics and existing tree bagger (TB) model. The mean absolute percentage error is noted 47%, 64% and 41% better than the TB model at MPS-3 to MPS-5 respectively. The proposed DRTSEM can efficiently tackle the nonlinear characteristics of the heterogeneous and multi-source loads and moreover increase accuracy and reduce the error between actual and forecasted load demand. The modeling results proved that the use of DRTSEM renders more accurate utility energy planning and management compared with the existing ensemble approaches.


If environmental footprint attributable to various consumption patterns are evaluated, monetary transactions in the environmentally-extended input-output analysis need to be linked to household-specific expenditures. However, while the former are recorded in basic prices, the latter is typically recorded in purchaser's prices, adding a commodity tax and margins to basic prices. Product homogeneity assumption —inherent to input-output analysis — implies that two identical products sold to consumers with different retail trade margins are responsible for different footprints. In this paper we investigate how footprint attributable to Food and Goods is affected across household income classes if we relax the homogeneity assumption and assume different allocations of retail trade margins across the income classes. While different allocations affect footprints of the two Consumption groups significantly, in particular in the highest deciles, the effect on total footprint is very small, up to 10% even for two extreme cases of margins allocation.


To develop an accurate segmentation model for the prostate and lesion area to help clinicians diagnose diseases, we propose a multi-encoder and decoder segmentation network, denoted Muled-Net, which can concurrently segment the prostate and lesion regions in an image. The model performs parallel calculations for dual input. In two encoder branches of the model, a new transformer encoder is used to overcome the fact that only information from the neighborhood pixels can be captured, increasing the ability to capture global dependencies. Furthermore, given the usually small size of the lesion, ASPP and feature fusion are merged to expand the perceptual field and retain more contextual information of the shallow layer in decoder. To the best of our limited knowledge, there is no public dataset for the segmentation of the prostate and its lesion regions. So we made a publicly usable dataset. Muled-Net is compared with other deep learning methods, FCN, U-Net, U-Net++, and ResU-Net with four-fold cross-validation. Of all 218 subjects, 140 healthy individuals and 78 patients with prostate cancer were included in this work. Average Dice of 95%, Iou of 89%, sensitivity of 94%, 95HD of 9.56, and MSD of 0.66 are achieved for the prostate segmentation and average Dice of 89%, Iou of 82%, sensitivity of 92%, 95HD of 11.16, and MSD of 1.09 for the segmentation of the prostate lesion regions. The performance of the proposed model has made significant improvements to the segmentation of the lesion regions in particular, suggesting that the model could be considered as an auxiliary tool to ease the workload of physicians and help them in making treatment decisions.


For a successful hydraulic fracturing operation, shear recovery and thermal stability are critical in terms of successful fracture creation and proppant placement. Sodium thiosulfate is one of the most commonly used gel stabilizers in fracturing gel. This paper reported a well in sulfur-free gas reservoir produced hydrogen sulfide as much as 20000ppm after hydraulic fracturing operation.
 A series of experiments were carried out to reveal the mechanism of hydrogen sulfide production. Results showed that in solution with PH less than 6.5, when the temperature is higher than 119 degrees Celsius, sodium thiosulfate will react with hydrogen ions to generate hydrogen sulfide. In this complex reaction, there is also precipitation of elemental sulfur, which may block the pores of the reservoir and thence counteract the effect of hydraulic fracturing. The acidic solution in a fractured well is from (1) Spent acid left downhole due to pre-acid used to reduce fracturing pressure, and (2) Sulfuric acid produced by the decomposition of ammonium persulfate which is used as gel breaker at high temperature.
 This paper proposed two solutions to the problem of high-temperature fracturing fluids,one is to use a sulfur-free temperature stabilizer,and the other is to create a non-acid downhole environment. The opinions provided by this paper can help the operators reduce the risk of the damage of hydrogen sulfide and protect the integrity of the well of high temperature fracturing wells.

This paper presents an implementation of efficiency optimization of reluctance synchronous motor (RSM) using a neural network (NN) with a direct torque control (DTC). The equipment circuit considered with iron losses in RSM is analyzed theoretically, and the optimal current ratio between torque current and exiting current component are derived analytically. For the RSM driver, torque dynamic can be maintained with DTC using TMS320F2812 DSP Controller even with controlling the flux level because a torque is directly proportional to the stator current unlike induction motor. In order to drive RSM at maximum efficiency and good dynamics response, the Backpropagation Neural Network is adapted. The experimental results are presented to validate the applicability of the proposed method. The developed control system show high efficiency and good dynamic response features with 1.0 [kW] RSM having 2.57 inductance ratio of d/q.


Applications of glyphosate and nitrogen and sulfur fertilisers and oversowing with kikuyu (Pennisetum clandestinum) and white clover (Trifolium repens) were used to improve the productivity of degraded upland pastures in a grazed site in south-east Queensland. The naturalised pastures based on Rhodes grass (Chloris gayana), paspalum (Paspalum dilitatum), carpet grass (Axonopus sp.) and kikuyu have been invaded by inedible grass weeds, swamp foxtail (Pennisetum alopecuroides), blady grass (Imperata cylindrica) and fine-leafed tussock (Poa sieberina). Herbicide application substantially reduced the density of grass weeds. However over 4 years, weeds reinvaded treated areas and periodic retreatment with herbicide will be necessary for long term control. Fertiliser and increased stocking pressure without herbicide treatment increased the yield of all grasses and increased liveweight gain (LWG)/ha but did not control the spread of the inedible grasses. The frequency and yield of kikuyu increased over the 4-year study period but because dry springs were experienced, white clover made little contribution. Over a 3-year grazing period, nitrogen fertiliser costs had not been fully recovered by increased LWG but animal response increased each year.

: Educational platforms have become important tools for e-learning; nonetheless, finding the appropriate educational resources to use often represents a tedious task for learners. Opinions in the educational domain are important information for decision making; they allow teachers to improve the teaching process and enable students to decide on the best educational resources. The large amount of data that is daily generated on the Web makes it difficult, however, to analyze opinions manually. Multiple opinion mining approaches are being proposed as a solution to this problem; this research work introduces EduRP, an education platform that integrates opinion mining techniques and ontology-based user profiling techniques. We specifically propose an opinion mining approach for Spanish text which consists of three main steps: 1) collect opinions from the EduRP platform, 2) process the opinions to normalize the text, and 3) obtain the polarity of the opinions using a machine learning approach. We also propose a profile customization approach that uses Semantic Web technologies, specifically ontologies, to integrate socio-demographic data from different social networks and from the platform itself. Finally, we assess the performance of our system under precision, recall, and F-measure metrics, obtaining average values of 81.85%, 81.80% and 81.54, respectively.


This paper proposed an improved control strategy of load distribution in an autonomous microgrid with multiple distributed generation units.Load sharing in an autonomous microgrid based improved V/δ droop control,instead of commonly used V/f droop control method,was investigated in this paper.The P-δ droop function and Q-V droop function employs additional derivative terms with modified gain respectively,which guarantee stability and good transient response.A supplementary loop was proposed around the primary droop control loop of each distribution generator(DG) converter which can modulate the d-axis voltage reference of each converter as to stabilize the system despite having high gains that are required for better load sharing.The simulation results verify that the proposed control strategy is effective for load distribution in the autonomous microgrid.

Pathways from childhood trauma to non-suicidal self-injury (NSSI) include those high-lighting emotional regulation and attachment, which have been supported by research in-vestigating the functions of NSSI. This pilot study sought to explore this further into this by examining which specific dimensions of attachment style and alexithymia predict self-injurious behaviour. Twenty-six young adults [mean (± SD) age 21.08 (± 3.95)], with ex-perience of NSSI were compared to a matched control group. The Toronto Alexithymia Scale and the Attachment Style Interview (ASI) were used. Findings revealed significantly greater levels of alexithymia, particularly the "difficulty identifying feelings" factor, in those with NSSI compared to the control group, as well as higher rates of insecure attach-ment style, particularly fearful insecure style. Examination of specific dimensions revealed ASI scales of "constraints on closeness" and "fear of rejection" providing the best model of NSSI. These findings provide empirical support for the affect regulatory function of self-injury, but also highlight the importance of the interpersonal boundaries function, which may provide a useful focus for treatment or intervention.
