Intelligent identification method of indicator number of substation instrument based on deformable convolutional neural network there are many equipment in substation, and the value and scale of oil thermometer, oil level gauge, pressure gauge and other instrument equipment reflect the operation state of most instruments and meters, which is particularly important. Therefore, the research on value reading of instrument equipment in substation is particularly key. At present, for the instrument recognition of substation, most studies use traditional image processing and machine learning methods. However, in the recognition process, due to the influence of uneven illumination, complex background, rotation angle, image blur, shooting angle, proportion change and other factors, the recognition accuracy of pointer instrument is low and its usability is poor. In order to solve the above problems, this paper combines the traditional image processing technology with the deep learning method, and proposes an automatic recognition method of substation pointer instrument based on deformable convolutional neural network. The idea of deformable volume is introduced to enhance the modeling ability of convolutional neural network, so as to improve the accuracy of instrument recognition. The main idea is that firstly, the deformable convolution neural network method is used to detect the instrument image in the image, then the residual neural network is used to extract the key points of the instrument dial and pointer, then the detected key points are used to fit the dial circle and pointer, and finally the readout value is calculated according to the deflection angle of the pointer relative to the scale. The experimental results show that this method is very effective for the identification of pointer instruments, and has high accuracy and practicability, which is conducive to promoting the realization of intelligent operation and maintenance of substation.


It is well-known that the category of presheaf functors is complete and cocomplete, and that the Yoneda embedding into the presheaf category preserves products. However, the Yoneda embedding does not preserve coproducts. It is perhaps less well-known that if we restrict the codomain of the Yoneda embedding to the full subcategory of limit-preserving functors, then this embedding preserves colimits, while still enjoying most of the other useful properties of the Yoneda embedding. We call this modified embedding the Lambek embedding. The category of limit-preserving functors is known to be a reflective subcategory of the category of all functors, i.e., there is a left adjoint for the inclusion functor. In the literature, the existence of this left adjoint is often proved non-constructively, e.g., by an application of Freyd's adjoint functor theorem. In this paper, we provide an alternative, more constructive proof of this fact. We first explain the Lambek embedding and why it preserves coproducts. Then we review some concepts from multi-sorted algebras and observe that there is a one-to-one correspondence between product-preserving presheaves and certain multi-sorted term algebras. We provide a construction that freely turns any presheaf functor into a product-preserving one, hence giving an explicit definition of the left adjoint functor of the inclusion. Finally, we sketch how to extend our method to prove that the subcategory of limit-preserving functors is also reflective.


In this paper, the power line interference removal in electrocardiogram (ECG) measurement signal is studied. First the FIR notch filter design based on Bernstein polynomial approximation is presented. The design method is simple and has an analytic solution. Then, a design example is illustrated to show the designed notch filter has exactly zero gain at notch frequency. Finally, an experiment of the 60Hz power line interference removal in ECG signal is made to demonstrate the effectiveness of the proposed filtering method.


With rapid advancement in technologies used in solid-state electronics, nowadays, the conversion and control of electrical power has become easy due to inclusion of power electronics-based devices. With the help of these devices, accurate and smooth control of electrical power conversion can be consummated in three-phase voltage source inverters. But uses of power electronics devices also result in Total Harmonic Distortion (THD), which distorts overall system performance. Eliminating some selected harmonic in a system can quickly be done by using optimization techniques. This manuscript focuses on analysis of harmonics in a 3-phase voltage source inverter using Gravitational Search Algorithm (GSA) and Particle Swarm Optimization (PSO) technique.


Background: Studying medicine is quite challenging as medical students have to study hours and hours which leads to continuous psychological stress resulting in decrease in sleep duration and quality. This study aims to determine the prevalence as well as the relationship of academic stress and pattern of sleeping problems among medical students. Methodology: In this cross-sectional comparative study, 128 non-obese medical students (calculated via WHO software) from First Year to Final year (18 -23 years old, BMI=18.5-24.9) were included and divided into 2 groups, with equal distribution of male and female undergraduate students, as non-medical students. Kessler Psychological Distress Scale (K10), Pittsburgh Sleep Quality Index Scale (PSQI) and percentage of Professional Examination Result were used to assess stress, sleep quality and academic performance, respectively. The collected data was analyzed using IBM SPSS-26 for normality distribution via Shapiro-Wilk and Kolmogorov Smirnov tests. Results: PSQI scores were less in the stressed [8.5(3 ─ 17)] as compared to non-stressed [6(1 ─ 17)] subjects (p=0.000) while academic score (percentage) in stressed [70.9(59 ─ 77)] was lesser than that of non-stressed [76.7(57 ─ 86)] subjects (p=0.000).Within the non-stressed subjects, K10 scores were positively correlated to PSQI scores (rho=0.294, p=0.018) and negatively correlated to academic score (rho= -0.319, p=0.010). Similarly in the stressed subjects there was a positive correlation between K10 and PSQI scores (rho=0.435, p=0.000) and a negative correlation between K10 and academic scores (rho= -0.251, p=0.045). Conclusion: Both, sleep quality and academic performance, reduces with increase in stress among non-obese medical students.


Birth control pills are considered the basic method of contraception after pregnancy interruption. If the pill is contraindicated hormone capsules provide a good alternative. With 83% of patients the 1st menstrual period after pregnancy interruption os ovulatory. After childbirth this usually occurs 50-60 days following delivery providing the woman does not breast feed. Breast feeding delays ovulation by 6 weeks. Subcutaneous hormone capsules of levonorgestrel are considered very suitable for contraception after pregnancy and have the added benefit of offering increased protection against infections. In the Finnish sample 91.7% of subjects continued their use after 1 year while only 73.9% in the comparison group continued the use of an IUD. Spontaneous expulsion of IUDs is reported as a problem. IUDs are recommended for contraception after childbirth if the woman breast feeds. They can be inserted 6 weeks after delivery. Risk of perforation is less if the device is placed later and the physician is experienced. Use of combination pills decreases production of milk and slows down the babys growth. Breast gland enlargements have also been observed. Levonorgestrel capsules slow the babys growth 4-6 months after birth but this difference levels off in older age groups. Developing countries have obtained a lot of experience with depot- medroxy progesterone acetate which increases lactation and does not alter the growth rate of children. However the longterm effects of hormones on the baby are not yet known. Post-partum sterilization is becoming more common although it produces a greater possibility of psychological reactions.


Objective:To explore the value of Edaravone on spinal cord injury perioperative period.Methods:58 patients with spinal cord injury were randomly divided into treatment group(30 cases) and control group(28 cases).The treatment group used Edaravone in perioperative period,after the injury 6~8 hours for intravenous drip,each 30mg,twice a day,14 days of continuous use.The control group did not use the edaravone.Used electronic spin resonance(ESR) technology to detect cerebrospinal fluid content of free radical before the operation 30 min and after decompression 30 min;preoperative and postoperative 1 day,2 weeks,3 months,respectively used the JOA score to assess neurological function,compared two groups curative effect.Results:Cerebrospinal fluid content of free radical in preoperative had no difference between the two groups,but after decompression half an hour and 24 hours,the treatment group decreased obviously than that in control group;after operation 2 weeks,the JOA score of treatment group was better than control group.Conclusion:Spinal cord injury patients in peri-operation period using Edaravone can reduce free radical concentration in cerebrospinal fluid,reduce postoperative relapse,and improve the postoperative curative effect.


Exemestane (EXE), an irreversible aromatase inhibitor, is employed as a therapy for hormone-dependent breast cancer. Several studies have also established the budding effects of genistein (GEN) in various types of cancer such as breast, prostate, as well as skin due to its feeble estrogenic and anti-estrogenic properties. Considering the promising benefits of GEN, it was combined with EXE to accomplish superior therapeutic efficiency with fewer side effects. The quantification of the exact concentration of EXE and GEN when delivered as a combination would be required for which HPLC method was developed and validated. For this purpose, the C18 ODS column having dimensions of 150 × 4.6 mm, 5 μm, using mobile phase A as methanol:water (35:15, v/v), with formic acid (0.01%), and B as acetonitrile (in the ratio of A:B––30:70 v/v) at a flow rate of 1 mL/min was commonly used. The Box–Behnken design was chosen as our experimental model, and the interactions among the independent and dependent variables were analyzed. Parameters like linearity, system suitability, specificity, precision (intra- and interday), robustness, ruggedness, LOD (limit of detection), and LOQ (limit of quantification) were selected for the validation of our proposed method. EXE and GEN were eluted individually at 245 and 270.5 nm, respectively, while both of the agents were determined simultaneously at 256 nm, showing retention time as 2.10 and 1.67 min, respectively, and the calibration plot was observed to be linear in the range of 5–110 μg/mL. Hence, the method that we developed and validated was found to be suitable for the identification of both the drugs simultaneously in combination and in our in-house-developed nanoformulation.


Many researchers are partnering with non-governmental organizations (NGOs) in order to carry out research on health related issues. In many ways NGOs are not limited to the same types of restrictions as government institutions, and can have greater flexibility in collaborating with researchers and incorporating them into their projects. Increasingly, NGO administrations visualize anthropological research as a valuable mechanism for evaluating their goals, internal working mechanisms, and the impact of their work on recipient populations provided the research does not represent a strain on the organization's financial capacity or the staff's time. Some organizations have even established particular mechanisms to evaluate potential research proposals, make sure that the investigations go as planned, and protect the rights of the participants through all stages of the research process. Collaborating with NGOs can ensure the direct applicability of the results of our research and in some cases, the translatio...


Technological innovations result not just from advances in science, but also social system reorganization. Reorganization is problematic, as various organizations and constituents pursue their interests and causes. Expanding on previous work in the economics and sociology of innovation, three cases from the retail food industry (frozen meat, boxed beef, and scanners) illustrate the process described in a politicized-context model of innovation. Market context, political contingencies, and established social relations all influence innovations. Thus, including these factors in the politicized-context model provides better understanding of the particular paths of innovation. Well-developed literatures in both economics and organizational theory describe factors that foster development and implementation of innovation. Previous studies find that a variety of contextual factors, such as the size of the firm, market share, industry concentration and barriers to entry, and changes in the technical or demand environment, determine whether a firm innovates (Ettlie 1983; Baldwin and Scott 1987; Schumpeter 1942; Mansfield 1968). However, previous work underemphasizes the importance of politics or social choice in this process. As Granovetter (1985) points out, economic organizations are embedded in social relations. Adopting an innovation requires reorganizing a complex web of social relationships. This article develops a model of innovation that includes both economic and social factors and analyzes three retail food industry innovations: frozen meat, boxed beef, and checkout scanners. Findings show that a combination of market and social factors shapes the final form of each innovation, illustrating the utility of the politicized-context model, as well as making its processes more explicit. Figure 1 depicts the politicized-context theory of innovation. As economists claim, context variables-such as the invention's and product's characteristics, and environmental factors-determine innovation outcomes, either a process or a product change. How


This paper gives an historical review of techniques used to map cerebrospinal fluid (CSF) drainage and describes the use of a new contrast agent which allows for quantitative imaging of lymphatic drainage from the CNS to cervical lymph nodes i n vivo. The first clear evidence of a connection between the cranial subarachnoid space and the cervical lymphatic system came from Schwalbe in 1869, and has been reinforced by several workers since using different methodologies [ 31. The perineural lymphatic pathway (PLE') was thought to be the predominant drainage route of CSF when Schwalbe demonstrated that Berlin blue dye, injected into the canine subarachnoid space, collected in the cervical lymphatics. That concept persisted until 1914, when Weed [6] injected a solution of ferrous cyanide into the lateral ventricles of rabbits and cats. He then perfused the animals with acid, causing blue crystals to precipitate primarily in the arachnoid villi and venous sinuses. Although some of the crystals were found along the cranial nerves and cervical lymphatics, Weed emphasized that the major pathway for CSF emux was the arachnoid villi-venous pathway. Bradbury's work [2], employing radio-actively labelled albumin, showed that tracers injected into the subarachnoid space could be recovered from the cervical lymphatics by cannulation of the main jugular lymphatic duct. The absolute contribution of the PLP to the absorption of cranial CSF varied between species studied. with 14-30% of the injected dose being recovered from the cervical lymphatics [2]. The size and molecular weight of the agent employed is important as particles less than 10nm in diameter readily pass through the


1in the 1950s used the novel tool of coronary sinus catheterisation to study the energy sources of human heart muscle in patients with heart failure. He showed that for its energy sources the heart uses mostly fatty acids and to a lesser extent glucose. Circulating free-fatty acids (FFA) could inhibit myocardial glucose oxidation. 2 In 1962 Sodi-Pallares et al. 3 launched the concept of metabolic therapy using glucose-insulin-potassium (GIK) solutions that reduced acute electrocardiographic signs of ischaemic damage. The mechanism whereby GIK provides benefit is in part by reducing the toxic high FFA levels that are found in early acute myocardial infarction (AMI) as a result of major catecholamine stimulation with acute adipose tissue lipolysis (Fig. 1). 4,5 In heart failure (HF), beta-blockade and GIK also reduce circulating FFA, while the newer drugs trimetazidine and ranolazine act metabolically to improve the condition of patients with ischaemia or HF. 6


In industrial equipment and home appliance applications, the electromagnetic compatibility compliance directive (ECCD) demands that electromagnetic interference side effects be eliminated or marginally minimized. The equipment must not disturb radio and telecommunication as well as other appliances. Additionally the ECCD also governs the immunity of such equipment to interference and seeks to ensure that this equipment is not disturbed by radio emissions when used as intended. Many types of absorbing materials are commercially available. However, many are expensive and not environmentally friendly. It is in the light of the above that we studied the electromagnetic absorption properties of ZnO-PCL nanocomposites prepared from cheap and abundant resources which are environmentally friendly (zinc and polycaprolactone). The test was carried out using a microstrip, open ended coaxial probe, and vector network analyzer. Amongst other findings, result showed that the ZnO-PCL nanocomposite has the capability of attenuating microwave frequency up to −18.2 dB due to their very high specific surface areas attributed to the nanofillers at 12 GHz.


Significance
 Official figures give Turkey a case fatality rate of 2.7% or 49 deaths per million, well below Western European figures and by no means the catastrophe predicted by outside observers. President Recep Tayyip Erdogan is leaving his health minister to handle the crisis. He himself is showing no sign of changing course on foreign policy, although at home he is intensifying attacks on the opposition well ahead of elections due in 2023.

 The prospects for a currency shock are strong.

Let A be a commutative 0-algebra, fmite dimensional over 0. Let us consider a 0-involution on A, which we shall denote with an overbar. Let Λ be an order of A which is stable under this involution. All modules in this paper will be fmitely generated and reflexive — but not necessarily projective. To a reflexive Λ-module M we associate the hyperbolic ε-hermitian (where ε = 1 or -1) form H(M}, see Section l for the defmition. We shall say that a unimodular ε-hermitian form h : L χ L — » A is stably hyperbolic if the orthogonal sum of (L, h) with some hyperbolic ε-hermitian form is hyperbolic. The purpose of this paper is to study the following problem: are stably hyperbolic ε-hermitian forms hyperbolic? We prove that this is the case under suitable hypothesis, see Section 6.


Abstract Residual stress relaxation was investigated by subjecting specimens with various mean stress levels to strain controlled cyclic loading. The material studied was mild steel in three different conditions. The mean stress levels ranged from 100 to 200 MPa, and two strain amplitudes, 0·05 and 0·06%, were studied in detail. The residual stresses in the specimens were measured before and after mean stress relaxation experiments. It was found that experimental factors such as temperature variations and crack growth have a significant influence on the results. Based on the experimental results, it is proposed that the mean stress relaxation exponent should be divided into two parts: mean stress dependent and mean stress independent. The first includes the contribution of quasi-static relaxation, i.e. mean stress dependent plastic deformation. The second part includes the contribution of cycle dependent mean stress relaxation, which does not depend on the mean stress.


This article sets out to evaluate the dominant approaches that are used to explain democratic support with a particular interest in what can be learned from the case of post-communist Europe. The main argument is that the case of post-communist Europe illustrates the weakness of the dominant sociological and instrumental approaches. In post-communist Europe democratic support does not depend on a familiarity with democratic institutions and norms, a belief in the democratic form of government, the avoidance of economic deprivation or satisfaction with government performance. Instead it is suggested that an alternative, more nuanced understanding of the dominant instrumental approaches is suited to the case of post-communist Europe.


Phthisis.?During the past summer the subject of tuberculosis, its aetiology, prevention, and cure, has commanded a very large amount of attention. Amongst the many meetings and conferences at which this matter has been discussed we may mention the International Congress at Berlin, the meetings of the British Medical Association, Sanitary Institute, Royal Institute of Public Health, and the general meeting of the newlyformed Association for the Prevention of Consumption. Space will not permit of our dealing at length with the proceedings of the Berlin Congress,1 at which the study of sanatorium treatment was the prominent feature. In Germany every worker is insured against sickness, and for their own protection the assurance societies have founded sanatoria for the treatment of consumptives. Visits were paid to these sanatoria, which were found in excellent working order. The average cost per head is three marks a day. In the course of the


Using optical–optical and optical–NIR colors, we analyze the radial dependence of age and metallicity inside massive (M⋆ ≳ 1010.5 M☉), low-redshift (z < 0.1), early-type galaxies (ETGs), residing in both high-density group regions and the field. On average, internal color gradients of ETGs are mainly driven by metallicity, consistent with previous studies. However, we find that group galaxies feature positive age gradients, ∇t, i.e., a younger stellar population in the galaxy center, and steeper metallicity gradients, compared to the field sample, whose ∇t ranges from negative in lower mass galaxies to positive gradients at higher mass. These dependencies yield new constraints on models of galaxy formation and evolution. We speculate that age and metallicity gradients of group ETGs result from (either gas-rich or minor-dry) mergers and/or cold-gas accretion, while field ETGs exhibit the characteristic flatter gradients expected from younger, more metal-rich stars formed inside-out by later gas cooling.


AbstractAn aspect of the apparent independence of educational innovation and educational research was investigated. Thirty-four professors of educational psychology and fifty junior high school teachers ranked in importance eight kinds of information about an educational innovation and evaluated the credibility of eight sources of educational information. The correlation between the rankings by each faculty was insignificant, but the correlation between the credibility evaluation by each faculty was .84 and significant. Each faculty generally found its own colleagues and their activities more important and credible; an important finding was that teachers regarded standardized test research results as much less important than the professors who regarded it as most important.

Immersion tanks usage expediency is justified in primary poultry processing department. It is proved that this tanks usage with 0.07% peracetic content solutions of technologic aid means in poultry slaughtering department gives the possibility to decrease carcasses surface insemination after defeathering by 34.7% with 10 s exposition and solution temperature 35±2°C and to decrease insemination by 48.34% before cooling bath with 9 s exposition and solution temperature 9±1°C. Additional antimicrobial carcasses treatment doesn't change its sensory qualities except the surface weak bleaching.


A double-beam actuator (DBA) is designed in this study for attenuating the harmful vibration. Its finite element model including the folded beam, glue layers and piezoelectric laminar is developed in commercial software ANSYS. DBA's dynamic characters are analyzed by employing modal and transient analysis in ANSYS. The calculated results are used to develop an explicit state space model by using the observer/Kalman filter identification (OKID) technique and Eigen-system Realization Algorithm (ERA). The robust H2 controller is designed based on the identified state space model and it is then incorporated into the ANSYS finite element model to perform the close loop controlling simulation. The results of simulation show the settling time reduce to 0.06s with active control under impulse exciting and the response amplitude decrease 20 dB under sine exciting, which demonstrate the validity of DBA in application of active control.


bstract—Grip force modulation has a rich history of reearch, but the results remain to be integrated as a neuroomputational model and applied in a robotic system. Adapive grip force control as exhibited by humans would enable obots to handle objects with sufficient yet minimal force, hus minimizing the risk of crushing objects or inadvertently ropping them. We investigated the feasibility of grip force ontrol by means of a biological neural approach to ascertain he possibilities for future application in robotics. As the erebellum appears crucial for adequate grip force control, e tested a computational model of the olivo-cerebellar sysem. This model takes into account that the processing of ensory signals introduces a 100 ms delay, and because of his delay, the system needs to learn anticipatory rather than eedback control. For training, we considered three scenarios or feedback information: (1) grip force error estimation, (2) ensory input on deformation of the fingertips, and (3) as a ontrol, noise. The system was trained on a data set consistng of force and acceleration recordings from human test ubjects. Our results show that the cerebellar model is capale of learning and performing anticipatory grip force control losely resembling that of human test subjects despite the elay. The system performs best if the delayed feedback ignal carries an error estimation, but it can also perform well hen sensory data are used instead. Thus, these tests indiate that a cerebellar neural network can indeed serve well in nticipatory grip force control not only in a biological but also n an artificial system. © 2009 IBRO.

This paper critiques one assessment strategy of a level 9 academic writing module. The module supports masters students in a School of Business by utilising a number of innovative approaches to teaching and assessing of academic writing skills. The assessment instruments include a portfolio of evidence of improvement in writing skills and a series of online discussion postings; the module is 100% continuously assessed. The use of portfolio is critiqued based on both validity and reliability of the assessment instrument, and also on conformity with the concept of formative assessment. 1: Introduction The system for critique is an assessment strategy of a masters level, 5 credit, academic writing module. The module is designed to support taught masters students in a School of Business, and is 100% continuously assessed. It provides a novel approach to the teaching and assessment of writing skills, using a virtual learning environment (VLE) with assessed discussion postings and a portfolio. Investigation of this assessment strategy may add to the body of work on supporting student writing (Wingate, 2006; Dowling and Ryan, 2007; Cleary et al, 2009). The focus of this critique is a portfolio of evidence of improvement in writing skills. It includes: 1. Tutor and peer review of a draft assignment from another module, usually the dissertation proposal. 2. Final, re-drafted assignment based on feedback from peer and tutor review (Bharuthram and McKenna, 2006). 3. Reflective account of improvement in writing skills. 4. In-class reflections on current state of knowledge, explicitly linked to improvement in writing skills within the reflective account.


In this work, we propose the use of an electrically small dipole antenna arrays as a microwave sensor combined with a classification algorithm for near field microwave breast tumor detection. The proposed sensor has high sensitive to detect any changes or abnormality in the dielectric properties of the breast tissues. Detecting the existence of the breast tumors are expected by estimating the variations in the response of the reflection coefficient of the sensor. The Principle Component Analysis (PCA) feature extraction technique is applied to accentuate the variance in the sensor responses for both healthy and tumourous cases. We show that when a numerical realistic breast with and without tumor cells is placed in the near field of the sensor, the sensor is capable of detection tumorous with various sizes placed in single locations at two different stand off 5 mm and 10 mm respectively.


Small-world networks have become an important model for understanding many complex phenomena in science and in sociological contexts. One tool for exploring the critical and phase transitional behaviour in small-world systems is to simulate known models on grids and networks that have been re-wired using the small-world approach. A well known model for studying phase transitions is the Ising spin model. This system is usually studied using an artificial Monte Carlo dynamics scheme and for the study of large model systems fast update algorithms based on whole cluster updating are necessary. These algorithms can not be applied to arbitrarily re-wired models. In this paper we apply a special pair-wise re-wiring that conserves the number of connected neighbours of each spin site and to which fast cluster update algorithms can be applied. We describe the algorithm and its implementation and present some convergence results which are compared with those from more traditional Monte Carlo approaches.


A stationary principle for the Sturm‐Liouville system with inhomogeneous boundary conditions leads to an approximate solution in which nonorthogonal expansions are used. It is shown that if the nonorthogonal functions are chosen to be the eigenfunctions of a similar Sturm‐Liouville equation, then the numerical solution of the boundary value problem no longer involves an integration of a second derivative, but only the more simple integration of a function. As an illustration, formulas for calculating the nuclear phase shifts of a Schrodinger equation with a long‐range Coulomb potential are presented in the notation of R‐matrix theory. The numerical convergence of the method is investigated for α‐α nuclear scattering from real potentials that have a repulsive core followed by a short‐range attraction (Ali and Bodmer). Generalizations of the method have been applied in nuclear physics to coupled differential equations and to eigenvalue problems.


Objective. To investigate a nosocomial outbreak of infection with multidrug-resistant (MDR) Acinetobacter baumannii in the intensive care units at China Medical University Hospital in Taiwan. Design. Prospective outbreak investigation. Setting. Three intensive care units in a 2,000-bed university hospital in Taichung, Taiwan. Methods. Thirty-eight stable patients in 3 intensive care units, all of whom had undergone an invasive procedure, were enrolled in our study. Ninety-four A. baumannii strains were isolated from the patients or the environment in the 3 intensive care units, during the period from January 1 through December 31, 2006. We characterized A. baumannii isolates by use of repetitive extragenic palindromic–polymerase chain reaction (REP-PCR) and random amplified polymorphic DNA (RAPD) fingerprinting. The clinical characteristics of the source patients and the environment were noted. Results. All of the clinical isolates were determined to belong to the same epidemic strain of MDR A. baumannii by the use of antimicrobial susceptibility tests, REP-PCR, and RAPD fingerprinting. All patients involved in the infection outbreak had undergone an invasive procedure. The outbreak strain was also isolated from the environment and the equipment in the intensive care units. Moreover, an environmental survey of one of the intensive care units found that both the patients and the environment harbored the same outbreak strain. Conclusion. The outbreak strain of A. baumannii might have been transmitted among medical staff and administration equipment. Routine and aggressive environmental and equipment disinfection is essential for preventing recurrent outbreaks of nosocomial infection with MDR A. baumannii.


Objective To explore the effect of propofol-mild hypothermia on the apoptosis of neural cells in rat′s brain after traumatic brain injury by investigating the expression of Bax in this experiment.Methods By applying Feeney′s brain injury model, health male SD rats were divided randomly into five groups, eight rats for each group: sham-injured group (S), only treated with opening the skull without brain injury; model group (M), treated as Feeney′s brain injury model; mild hypothermia-treated group (H), 15min after brain injury, maintained the body temperature between 32-34℃(anal temperature) for 3h by physical hypothermia method;propofol-treated group (P), propofol (50mg/kg) injected intraperitoneally immediately after brain injury, then the same dose was administered after 1h;propofol-mild hypothermia-treated group (PH), propofol injected combined with mild-hypothermia. The rats were killed 1days after brain injury. The number of apoptotic neuron around the injured cerebral cortex was quantified by TUNEL method, the expression of Bax was observed by immunohistochemical staining.Results The quantity of TUNEL (+) neural cell was the highest in Group M, and Group H and P was higher, and in Group PH was the lowest in four groups. Compared with Group M, the expression of Bax protein in Group H and P was decreased markedly (P0.05, P0.01). The expression of Bax protein in Group PH was decreased significantly, compared with Group M (P0.01), and also with Group H and P (P0.05, P0.01).Conclusion After brain injury, the apoptosis of neural cells around the injured tissue increased significantly. Propofol-mild hypothermia could reduce the apoptosis of neural cells in the injured rat brain tissue, thus could protect the injured brain tissue through its anti-apoptic function by adjusting the expression of Bax.


Dielectric elastomer actuators (DEAs) are flexible and thin. They consume little electrical power but high voltage is required to drive DEAs. One research issue is to scale down high-voltage circuits (HVC) to construct untethered soft robots. In particular, circuits that can supply high voltage to multiple DEAs are critical for complex control of applications. In this study, we propose a design methodology for a HVC with four output ports. We develop the HVC in two steps and compare the sizes and weights of the different modifications (HVC ver.l, 2, and 3). The size and weight of the HVC ver.3 are 5024 mm2 (80-mm diameter) and 56.5 g, respectively, which are 112.33 g lighter and 1600 mm2 smaller than ver.l. Furthermore, the circuit weight required to build each output port was 14.13 g, the lightest among the previous studies. Because applying a voltage induces large current flows in the DEA, transients in the voltage waveform output from the HVC should be eliminated. Here, improving the transmitting command method from the microcontroller eliminates the transients in the high-voltage output waveform. We also compare the area strains of DEAs driven by HVC ver.3 and a desktop high-voltage equipment. The area strain of DEAs driven by HVC ver.3 does not return to 0% when the voltage is 0 V since the accumulated charge in the DEAs is not released immediately. However, the peak-to-peak area strain during the cycle is 4.6% for HVC ver.3 and 5.1% for the desktop high-voltage equipment, a difference of only 0.5%. This research should contribute to the realization of a system that simultaneously controls multiple DEAs or high-voltage actuators.

Empirical dependence of level of acoustic noise on transport loading for the winter and summer period is received.


This paper reviews the schemes of two beam accelerators proposed for electron-positron colliders in the TeV energy range. Attention is given to the different methods of generating and handling the high-charge drive beam.

A job analysis was conducted to develop specifications for the physical education assessment of The Praxis Series: Professional Assessments for Beginning Teachers and to support the content relevance of the assessment. An advisory committee consisting of physical education teachers, teacher educators, and administrators worked with measurement psychologists to describe a knowledge domain important for newly licensed/certified physical education teachers to perform their jobs competently. The knowledge areas were judged for importance by a national sample of 815 physical education teachers, administrators, and college faculty. As a result of this survey, 128 knowledge statements were judged as important for newly licensed/certified physical education teachers.


Guanine was identified by ultraviolet absorption, infrared spectra, and thin layer chromatography in the white pellet excreta of adults of 3 argasid and 6 ixodid species, and of each nymphal instar and the adult of Argas (Persicargas) arboreus Kaiser, Hoogstraal & Kohls. All argasid and ixodid samples contained guanine. Ixodid excreta also consisted of 4.2–15.1% of a 2nd purine compound which is more soluble in water than guanine and which has not previously been described or recorded.


Shalateen is considered one of the strategic areas for the security of Egypt from the south-eastern side which requires agricultural development. The objective of this study is to evaluate the soil quality using the integration of remote sensing and GIS. Thus, geopedological soil map was generated including the required soil characteristics. Twenty-six soil profiles were selected to represent the different mapping units. Assessment of soil quality is based on three main quality indices, chemical index (CI), physical index (PI), and fertility index (FI). The results revealed that chemical quality ranges from high to low quality, where most of the study area has a moderate quality. Physical quality varies from high to moderate, where most of the study area is classified as high quality. Fertility index in the study area fell into moderate and low classes. Finally, integration of the three indices showed that the study area is classified as a moderate soil quality. These results can be utilised to plan for the agriculture development taking into consideration the limiting factors and the potential use of the entire area.


We develop two methods for combining finite state line codes and error correcting codes, a state-splitting method for finite state encoders with variable rate and a Gray code like numbering of constrained sequences. The method can be used to prevent severe error propagation caused by using long code words.


Research work on the ergonomics of bicycle, reported in literature, mainly deals with sports and rehabilitation activities. However, the use of pedal power for occupational work such as stationary farm operations has got scant attention in the past. Keeping these points into consideration a study was conducted at CIAE, Bhopal to optimise the design parameters for a pedal operated rotary device (dynapod), which could be used as an interface between human worker and any rotary type process machine. The developed dynapod was interfaced with a hand operated rotary maize sheller and the performance of the machine and drudgery reduction while operated in pedalling mode was quantified and compared with those of hand cranking mode. The results indicated a significant increase in output capacity of the machine (282.7 kg/h versus 144.42 kg/h) with a significant reduction in work pulses (ΔHR) during the operation of the machine (35 beats/min versus 59.4 beats/min) in pedalling mode using dynapod. It was concluded that the rotary maize sheller should be popularised along with the dynapod for its better adoptability by the farmers.


Class Activation Map (CAM) is a commonly used solution for weakly supervised tasks. However, most of the existing CAM-based methods have one crucial problem, that is, only small object parts instead of full object regions can be located. In this paper, we find that the co-occurrence between the feature maps of different channels might provide more clues for object locations. Therefore, we propose a simple yet effective method, called Frequent Class Activation Map (FreqCAM), which exploits element-wise frequency information from the last convolutional layers as an attention filter to generate object regions. Our FreqCAM can filter the background noise and obtain more accurate fine-grained object localization information robustly. Furthermore, our approach is a post-hoc method of a trained classification model, and thus can be used to improve the performance of existing methods without modification. Experiments on the standard dataset CUB-200-2011 show that our proposed method achieves a significant increase in localization performance compared to the original existing state-of-the-art methods without any architectural changes or re-training.


We demonstrate the effects and role of anisotropy and particle size distributions upon the values of constitutive parameters determined from experimental M(H) loops of single domain nanoparticle systems. We employ experimental and magnetic material parameters as inputs to a numerical programme run from a graphical user interface (GUI) to permit modelling and interpretation of experimental data and assessment of the stability of the constitutive parameters so derived and characterisation of the departures observed from pure Langevin behaviour.


We study the effect of elastic anisotropic biaxial strain on the light emitted by neutral excitons confined in different kinds of semiconductor quantum dots (QDs). We find that the light polarization rotates by up to 80 degree and the excitonic fine structure splitting varies by several tens of $\mu$eVs as the strain is varied. By means of a continuum model we mainly ascribe the observed effects to substantial changes of the hole wave function. These results show that strain-fields of a few permill magnitude are suffcient to dramatically modify the electronic structure of QDs.


Designers in the era of big data not only use computers as modern design media, but more importantly, they must have the ability to grasp, control and use various information quickly and accurately. With the rapid development of digital technology and the construction market, the concept of BIM came into being. At present, BIM is gradually accepted by the construction industry. As a new technical concept, BIM is promoting the development of architectural design and other industries. At the same time, big data has become a hot topic and a starting point for solving problems. This article introduces the specific concept and development trend of the new computer information technology-building information model. This article focuses on analyzing the revolutionary changes brought about by the application of BIM in interior design, and further elaborates the advantages of building information modeling technology in interior design through two examples.


Investor Relations has become a good reason to keep a Home Page in the Web. Several companies with shares in the stock market already divulge their quarterly and annual reports online. To investigate how companies are using the Internet to communicate with investors, this article studies the case of Banco do Brasil, which searches to construct relations with shareholders, press, institutions of the stock market and financial analysts.

Objective: Defect classification is an essential part of software development process models as a means of early identification of patterns in defect inflow profiles. Such classification, however, may often be a tedious task requiring analysis work in addition to what is necessary to resolve the issue. To increase classification efficiency, adapted schemes are needed. In this paper a light-weight defect classification scheme adapted for minimal process footprint -- in terms of learning and classification effort -- is proposed and initially evaluated. Method: A case study was conducted at Volvo Car Corporation to adapt the IEEE Std. 1044 for automotive embedded software. An initial evaluation was conducted by applying the adapted scheme to defects from an existing software product with industry professionals as subjects. Results: The results showed that the classification scheme was quick to learn and understand -- required classification time stabilized around 5-10 minutes already after practicing on 3-5 defects. The results also showed that the patterns in the classified defects were interesting for the professionals, although in order to apply statistical methods more data was needed. Conclusions: We conclude that the adapted classification scheme captures what is currently tacit knowledge and has the potential of revealing patterns in the defects detected in different project phases. Furthermore, we were, in the initial evaluation, able to contribute with new information about the development process. As a result we are currently in the process of incorporating the classification scheme into the company's defect reporting system.

The 2016 MW 7.8 Kaikoura earthquake in New Zealand may have involved co-seismic slip on more than 10 distinct faults. We attempt to assess the sequence of rupture on the segments as well as the contribution of the different segments to the recorded ground motion in New Zealand. First, we approximate the segments as points sources to determine the temporal sequence of faulting and to determine the relative contribution to the seismic moment. We reduce the overall number of segments to 10 crustal faults. We invert strong motion, geodetic and teleseismic body and surface wave data to provide a spatio-temporal map of slip and rupture time.


Penstemon subgenus Dasanthera is a group of nine species distributed at high elevations in western North America. Hybridization is common in the subgenus when two or more species occur in sympatry. We examined evolutionary trends and the importance of hybridization to the evolution in the subgenus. Phylogenetic and biogeographic patterns among members of Penstemon subgenus Dasanthera were assessed using nuclear ribosomal ITS and chloroplast matK sequence data, and inter-simple sequence repeat (ISSR) markers. These data support previous hypotheses suggesting that the Cascade-Sierra Nevada lineage is derived from the northern Rocky Mountain lineage. Furthermore, there is a shift in growth form from suffructescent perennials to evergreen subshrubs concurrent with migration to the Cascade-Sierra Nevada mountains. Within the Cascade-Sierra lineage, P. newberryi and P. rupicola exhibit oral characters that may represent adaptations for hummingbird pollination. The ISSR data demonstrate the utility of dominant markers for reconstructing phylogenetic relationships at the interspeciŽc level. Reconstructing evolutionary relationships among closely related species using DNA sequence data is often complicated by insufŽcient data for adequate resolution. In plants, the nuclear ribosomal internal transcribed spacer (ITS) region, quickly-evolving chloroplast introns, and chloroplast intergenic spacers have been used to examine species-level relationships with considerable success (Soltis and Soltis 1998). However, these regions are sometimes insufŽcient for resolving relationships among closely related species (e.g., Small et al. 1998). Furthermore, lineage sorting, introgression, and gene paralogy may complicate phylogenetic reconstruction. Hypervariable dominant markers include randomly ampliŽed polymorphic DNA (RAPDs), ampliŽed fragment-length polymorphisms (AFLPs), and inter-simple sequence repeat (ISSR) markers. Recently, this class of markers have been used to examine genetic variation at the intraspeciŽc level (Rieseberg and Gerber 1995; Stewart and Porter 1995; Friar et al. 1996; Tsumura et al. 1996; Schierenbeck et al. 1997; Esselman et al. 1999), identify species-diagnostic markers (Arnold 1993; Dawson et al. 1996; Smith et al. 1996; Daehler and Strong 1997; Wolfe et al. 1998; Martin and Cruzan 1999; Bartish et al. 2000), identify genetic trait loci, (Rafalski and Tingey 1993; Zietkiewicz et al. 1994; Blair et al. 1999; Arcade et al. 2000; McGregor et al. 2000), and examine interspeciŽc relationships (Borowsky et al. 1995; Federici et al. 1998; McArthur et al. 1998; McArthur et al. 1998; Pacak et al. 1998; Nair et al. 1999; Zouhair et al. 2000; Wolfe and Randle 2001). However, evolutionary analysis of dominant markers can be complicated by unreliability (Williams et al. 1993; Smith et al. 1994) and questions of the homology of comigrating bands, especially as taxonomic distance increases (Rieseberg 1996; Adams and Rieseberg 1998). Furthermore, data analysis within a phylogenetic context is compromosed by the anonymous nature of bands, inability to evaluate heterozygosity, and potentially high levels of band polymorphism (Wolfe and Liston 1998). Although studies by Rieseberg (1996) and Adams and Rieseberg (1998) demonstrate that non-homology of comigrating bands does not have a great effect on the overall results or data interpretation based on ordination methods, no consensus exists on how dominant marker data should be analyzed. Ordination methods provide a metric of distinctiveness of groups or species, but do not address phylogenetic relationships among groups or species (Adams and Demeke 1993). Tree-based ordination methods, such as Neighbor-Joining (Saitou and Nei 1987) and UPGMA (Sneath and Sokal 1973), are often used to examine relative relationships among species, clusters of individuals or populations. However, these methods may force hierarchy onto non-hierarchical patterns such as those caused by hybridizing species lineages. Phylogenetic analyses have been used in some studies (Borowsky et al. 1995; Huang and Sun 2000; Wolfe and Randle 2001) but may be inappropriate in cases where individuals are considered OTUs and bands are polymorphic within species. Further, accounting for intraspeciŽc polymorphisms is rarely addressed (however, see


In this paper an attempt has been made to optimize ply stacking sequence of single piece E-Glass/Epoxy, HM Carbon/Epoxy and Boron/Epoxy composite drive shafts using particle swarm optimization (PSOA). PSOA programme is developed using MATLAB V 7 to optimize the ply stacking sequence with an objective of weight minimization. The weight savings of the E-Glass/Epoxy, HM Carbon/Epoxy and Boron/Epoxy shaft are 51%, 87% and 85% of the steel shaft respectively. The optimum results of PSOA obtained are compared with results of genetic algorithm (GA) and found that PSOA yields better results than GA.


Lack of investment in the railways in Ireland during the 1980s and 1990s led to safety problems. In 1998 a report by International Risk Management Services recommended a 15-year investment programme to address the problems. The Irish Government committed itself to an initial 5-year 550m Euro safety investment programme. A strategic rail review published in 2003 showed that the network needed expenditure of 4-5 billion Euros over 20 years. In 1998, EU funding was allocated to increase capacity in the Dublin area, through infrastructure work and the purchase of rolling stock, and for track upgrading. Investment in the inner-city network is planned. In 2004, the Minister for Transport agreed in principle to a 10-year financial package for transport investment, allowing a greater degree of strategic planning. The proposals for Dublin include a metro and improvements to the light rail lines in the city centre. The strategic plan for Cork recommends reopening the line to Midleton. Opening up the bus market is being considered, but there are no plans for railway privatisation. Public-private partnerships are being considered for metro and light rail.


In the famous last paragraph of On the Origin of Species, Darwin compared the "fixed law of gravity", which causes the Earth to orbit the Sun, with the evolution of species by natural selection. This may be the first recorded case in biology of "physics envy": the view that the proper task of the life sciences-in Darwin's case, evolutionary biology-is to emulate physics by establishing general laws and working out their consequences. Although we don't speak of "laws" in biology, we do have lawlike generalizations, including the near-universality of the genetic code and the mechanism for translating DNA and RNA into proteins.

In this paper the relation between the use of dual class shares and the risk of takeovers is explored. The results stress the need to control for the identity of the controlling owner in studies of corporate control and firm performance. For family controlled firms, it is found that both the hazard rate of takeover and firm market value decline with the wedge between the families' voting rights and cash flow rights. It is concluded that due to non-transferable private benefits of control in family firms, dual class shares reduce the likelihood that the family will accept the terms of value enhancing takeovers and this translates into lower firm value.


Summary

When meat or fish is cooked, a number of mutagenic pyrolysis products may be formed. The amounts produced depend on the type of food and the cooking conditions used. More mutagenic activity is associated with the cooking of muscle protein than with organ meat such as liver and kidney. Grilling and frying, because of the higher surface temperatures generated, produce more mutagenic activity in meat than do other methods of cooking. The quantities of mutagens formed, even by frying, are very small (about 20ug/kg), but they are, nevertheless, a cause for concern because these compounds are amongst some of the most potent mutagens known. Furthermore, they bind to DNA in vivo and, when fed to rats and mice, induce tumours in various organs, including liver and the intestine. However evidence is accumulating that other dietary components can influence the genotoxic activity of the 'cooked food mutagens'. For example, dietary fibre reduces the activity of the compounds in mice, whereas feeding quercetin, a flavonoid found in many vegetables, increases the mutagenic activity in vivo.


Angle's Class II malocclusion forms a major part of orthodontic practice. Over the past few years, non-extraction treatment and non-compliance therapies have become popular in the correction of dental Class II malocclusion. One of the methods to correct Class II malocclusion is to distalize upper molars.  This report describe the fabrication of an appliance to distalize maxillary molars using NiTi coil springs buccally as well palatally without the use of complicated piston assembly for the management of Class II, Division 1 malocclusion with minimal crowding in a 21 year old female patient.


Producing the "Ships and Aircraft of the U.S. N a w interactive mutti-media database display for the U.S. Navy Memorial Visitor Center raised Interesting design problems: How should over 3,000 historical photographs and accompanying data be classified? How should these classifications be developed to anticipate the needs of a very general public audience? How wll the classification system be executed in software? A careful audience analysis and a very flexible software approach ultimately yielded a successful design.


Wound care following lower limb arthroplasty has not been subject to in‐depth clinical research, primarily because such wounds usually heal without complication. However, when prosthetic implants are used, serious wound problems can be disastrous (Whitehouse et al. Infect Control Hosp Epidemiol 2002;23:183–9; Lindwell OM. Clin Orthop Relat Res 1986;211:91–103). We report the results of a prospective, randomised, controlled trial comparing a hydrofibre (Aquacel®) and central pad (Mepore®) dressing in the management of acute wounds following primary total hip or knee arthroplasty left to heal by primary intention. Dressing performance was measured in 61 patients receiving total hip or knee replacements. There was a significant reduction in the requirement for dressing changes before five postoperative days in the hydrofibre group (43% compared with 77% in the central pad group), and there were fewer blisters amongst patients in the hydrofibre group (13% compared with 26% in the central pad group). We conclude that there is a potential role for hydrofibre dressing in the management of arthroplasty wounds.


We propose a new scrambling approach for regions of interest in compressed H.264/AVC bit streams. By scrambling at bit stream level and applying drift reduction techniques, we reduce the processing time by up to 45% compared to full re-encoding. Depending on the input video quality, our approach induces an overhead between −0.5 and 1.5% (high resolution sequences) and −0.5 and 3% (low resolution sequences), respectively, to reduce the drift outside the regions of interest. The quality degradation in these regions remains small in most cases, and moderate in a worst-case scenario with a high number of small regions of interest.


Offshore industry assets are capital intensive and downtime can have severe financial consequences. Additive manufacturing (AM) based supply chains can potentially offer offshore industry stakeholders a strong value and a competitive advantage, from lower costs and lead times to greater flexibility and agility. However, the current adoption level of AM for the offshore industry is very limited, despite the consensus that such technology could have potential applications for spare parts, repair and even new builds. While adoption of additive manufacturing could be a source of positive change, inadequate understanding of requirements regarding approval, qualification and certification processes required by regulatory authorities could hinder the progress of AM adoption in the offshore industry.
 Currently, there are only a handful of additive manufacturing standards available for early adopters of AM technology. Hence, costly and time-consuming nonstandard testing to ensure the integrity of the 3D printed parts is deterring the wider applications of additive manufacturing in the offshore sector, underscoring the need to develop optimal practice guidelines and standards from design to part build to operation.
 This paper aims to highlight several key challenges that hinder the adoption of AM in the offshore sector and to propose various solutions that can help to overcome these. Due to its novel approach, the risk-based certification pathway discussed in this paper will help the offshore industry and its supply chain ecosystem to build trust and confidence in the adoption of this emerging technology, which otherwise might not be possible.


Calcium (Ca2+) is a major second messenger in the regulation of different forms of synaptic and intrinsic plasticity. Tightly organized in space and time, postsynaptic Ca2+ transients trigger the activation of many distinct Ca2+ signaling cascades, providing a means for a highly specific signal transduction and plasticity induction. High‐resolution two‐photon microscopy combined with highly sensitive synthetic Ca2+ indicators in brain slices allowed for the quantification and analysis of postsynaptic Ca2+ dynamics in great detail. Much of our current knowledge about postsynaptic Ca2+ mechanisms is derived from studying Ca2+ transients in the dendrites and spines of pyramidal neurons. However, postsynaptic Ca2+ dynamics differ considerably among different cell types. In particular, distinct rules of postsynaptic Ca2+ signaling and, accordingly, of Ca2+‐dependent plasticity operate in GABAergic interneurons. Here, I review recent progress in understanding the complex organization of postsynaptic Ca2+ signaling and its relevance to several forms of long‐term potentiation at excitatory synapses in cortical GABAergic interneurons.


We propose and experimentally realize a highly non-degenerate spontaneous parametric down-conversion (SPDC) source of narrowband photon pairs, with the signal photons near the zero-dispersion wavelength of SMF-28e and in the sub-THz bandwidth regime. Attempts are made to produce this source using periodically-poled potassium titanyl phosphate (PPKTP) in Type-II SPDC with 401 nm pump beam and Type-0 SPDC with 405 nm pump beam. The generated signal photons have temperature-tunable wavelength of 1307.5 nm and frequency bandwidth of less than 0.1 nm, limited by spectrometer resolution. The low jitter of the source has promising applications in quantum communication requiring high time resolution.


Although the importance of coronary functional abnormalities has been emerging, including epicardial coronary spasm (vasospastic angina, VSA) and coronary microvascular dysfunction (CMD), comprehensive evaluation of the abnormalities in the same population remains to be examined.

 We examined the significance of coronary functional abnormalities in a comprehensive manner for both epicardial and microvascular coronary arteries in patients with chest pain and unobstructive coronary artery disease (CAD) as well as their prognostic impacts.

 We prospectively enrolled 187 consecutive patients with suspected angina and unobstructive coronary arteries (M/F 113/74, 63.2±12.3 [SD] yrs.). We performed acetylcholine (ACh) provocation tests for coronary spasm, followed by functional tests for coronary microvascular function, including coronary flow reserve (CFR) and index of microcirculation resistance (IMR) during hyperemic state induced by intravenous adenosine. Among the 187 patients, ACh test identified 128 patients with VSA (68%). There was no significant difference in age, sex, or prevalence of traditional coronary risk factors between the non-VSA and the VSA groups. The median IMR value was significantly higher in the VSA group than in the non-VSA group [17.5 (12.0, 25.3) vs. 14.7 (10.7, 17.8), P=0.02], whereas CFR values were comparable between the 2 groups [2.51 (1.72, 3.35) vs. 2.66 (1.85, 3.64), P=0.34]. During the median follow-up period of 893 days, major adverse cardiac events (MACE), including cardiac death, non-fatal myocardial infarction, and hospitalization due to unstable angina pectoris, occurred in 10 patients (5.3%). Multivariable analysis revealed that IMR correlated with the incidence of MACE [hazard ratio (HR) (95% confidence interval), 1.05 (1.02–1.09), P=0.002] and receiver-operating characteristics curve analysis identified IMR of 18.0 as the optimal cut-off value for the incidence of cardiac events. When we divided the patients into the following 4 groups according to the cut-off value of IMR (>18) and the presence or absence of VSA; G1, IMR <18 without VSA (n=45); G2, IMR ≥18 without VSA (n=14); G3, IMR <18 with VSA (n=67); and G4, IMR ≥18 with VSA (n=61), the Kaplan-Meier survival analysis showed a significantly worse prognosis in G4 compared with other 3 groups (HR [95% CI] 6.23 [1.21–118.46], P=0.002) (Figure 1). Importantly, intracoronary administration of fasudil, a Rho-kinase inhibitor, significantly ameliorated IMR in G4 (P<0.0001) (Figure 2A), and %changes in IMR in response to intracoronary fasudil were more evident in G4 compared with other 3 groups (P<0.0001) (Figure 2B).

 These results provide the first evidence that in patients with chest pain and unobstructive CAD, epicardial coronary spasm and increased microvascular resistance are frequently coexisted with worse long-term prognosis, for which Rho-kinase activationmay be involved.


A new diagnostic system--heterodyne time sequential polychromator formeasuring electron temperature profiles in tokamak plasma is presented. Compared with the conventional heterodyne receiver using carcinotron local oscillator, the new system has higher scaning speed with much lower price.


The paper presents selected results of wider comparative experimental tests on masonry walls in full‐scale made of autoclaved aerated concrete masonry units. The walls were unreinforced and reinforced. The reinforcement in form of steel wire, glass, and basalt fiber meshes was applied in each masonry bed joint. The walls were subjected to simultaneous incrementing vertical loads and deflection of the structure which they are supported on. The carrying capacity of reinforced walls was up to 1.5 times higher than unreinforced walls. Test results of reinforced walls also showed lower values of deformation angles in relation to the walls without reinforcement for given load and deflection of support. In case of reinforced walls, much smaller widths of the cracks were obtained. The reinforcement allows to keep integrity of walls even after reaching the maximum load and deflection of supporting structure. The paper describes cracking and damaging mechanism of the walls as well.


The education you are getting is quite different from the training electrical and electronics engineers received 30 years ago. One reason is that technological advances have expanded the field to include many specialties. Engineers' training is much more specialized and theoretical than it was a generation ago. As the technology has grown in sophistication and business has become more complex, engineering teams have adapted by including not only more specialized EEs but also electrical/electronic technologists (EETs). With EETs to focus on practical problems, engineers can concentrate on analysis and design.


SiO_(2) colloidal solution were prepared, catalyzed by hydrolysis of Ethyl Silicate (Si(OC_(2)H_(5))_(4),TEOS), using NH_(3)·H_(2)O as catalyser, ethanol as solvent, the mixed liquor of ethanol and ditilled water was used to dilute the sol. The concentration of sol was 0.01g/mL, the particles of SiO_(2) in sol possesses negatives charge. Polyelectrolyte [Poly(diallyldimethylammonium chloride), PDDA] possessing positive charges and SiO_(2) complex films were fabricated on glass substrates via the electrostatic self-assembly multiplayer (ESAM) technique. SiO_(2) optic anti-reflective thin films were formed by heat-treating under different temperature less 520℃.The micro-structure, constitute, refractive index and thickness, anti-scratch intensity, laser damage threshold and light transmittance of the SiO_(2 ) films are characterized by thermal analyzer(DTA-TG), transmission electron microscopy(TEM), Fourier transform infrared(FT-IR), ellipsometry, Nd∶YAG laser damage facility 721spectrophotometer respectively. The experimental results show that the anti-scratch intensity, laser damage threshold, light transmittance are further improved after heat-treatment. PDDA /SiO_(2) complex thin film of 20 bilayers was heat-treated under 300℃ possesses the most high anti-scratch intensityand refractive index, under 400℃ possesses the most high light transmittance (99.2%)at wavelength 520nm, under 500℃ possesses the most high laser damage threshold(68J/cm~(2)).


Dramatic changes have transformed the landscape of nuclear medicine instrumentation over the last 50 y. Since the 1970s, diagnosing and treating diseases have evolved from a best-guess and treatment method to a more science-based test, prove-and-treat method. γ-cameras have evolved from stationary


A statistical model for austenitic stainless steels (SSs) for predicting the effect of boiling water reactor (BWR) environments on fatigue life for a range of temperatures and strain rates is developed based on the analysis of available material data from Europe, U.S., and Japan. Only fatigue data from polished specimens of wrought material tested under strain control were considered. Hollow specimens were not treated in the final calculations. The fatigue-life correction factors were defined as the ratio of life in water at 240 °C (464 °F) (reference conditions) to that in water at service conditions. The model is recommended for predicting fatigue lives that are 102–104 cycles.

The purpose of this research was to investigate the property of sensibility of silk fabrics by the linen-like finishing-used polyurethane resin. Subjective evaluations of preference and related sensory descriptors were estimated. Also, related physical and psychological variables were measured. And their correlations were investigated. The value of EM, WT, WC, MIU, and qmax of silk fabrics treated with polyurethane resin decreased and LT, B, 2HB, G, 2HG, 2HG5, and SMD increased. Physical variables which affected on the preference of summer fabrics are B, 2HB, G, 2HG5, qmax, MIU and LT. It was confirmed that silk fabrics treated with polyurethane resin were preferred as a summer fabric. Individual sensibilities that had effects on the preference of summer fabrics were softness including rough and cold. The intensities of weight value on sensory descriptors, which were related with the preference in summer environments, were in following orders: cold, rough, slippery, flexible, stiff and damp. There was no relationship between the subjective evaluation of preference and related sensory descriptors on the fabric and comfort sensation of fabric was derived from psychological variables


The invention discloses epoxy-modified water-based alkyd resin, water-based alkyd amino stoving varnish and a preparation method of the epoxy-modified water-based alkyd resin and the water-based alkyd amino stoving varnish, belonging to the technical field of high molecular materials. The preparation method comprises the following steps: mixing vegetable oil, bisphenol A glycidyl ether epoxy resin and polyhydric alcohols to synthesize an alcoholysate monoglyceride; then, carrying out esterification reaction with phthalic anhydride, then hydrating by using trimellitic anhydride, and finally neutralizing and dispersing to obtain the epoxy-modified water-based alkyd resin (as a component A); and then, mixing the component A with various types of amino resins (as a component B) and a certain amount of pigments and filler, cosolvent, neutralizer and deionized water to prepare the amino stoving varnish. By using vegetable oil as a main raw material, an extremely small amount of solvent is used, and the method hardly depends on petroleum and is low in cost and the production process is simple and easy to control. The prepared stoving varnish can be widely applied to the fields such as industrial corrosion prevention and belongs to the environment-friendly coating.


In the study, the author substantiates a sufficient number of degrees of freedom of the dynamic platform of the simulator of combat tracked vehicles in the Armed Forces of Ukraine. The analysis of perception by the mechanic-driver of dynamic characteristics is carried out. The types of spatial movements of the car body are determined. The direction of further development of the training system, which provides skills in driving, is determined
The analysis of the driver-driver's perception of the dynamic characteristics of a combat tracked vehicle showed that to ensure the formation of adequate basic driving skills at the initial stage of training and especially during further improvement or correction of previously acquired skills it is necessary to simulate all dynamic effects on the trainee. longitudinal and horizontal angular oscillations and movements of the machine; longitudinal and transverse linear accelerations that occur during acceleration, braking, skidding and turning of the machine
Thus, to ensure adequate simulation of the movement of the combat tracked vehicle, it is enough to supplement the existing two-stage dynamic platforms with a compact unit of simulation of movement in the turn, which will simulate the lateral sliding of the machine or its skidding. This will allow you to simulate the entire range of movements that are characteristic of the movements in the rotation of a real mobile object by reproducing two types of movements at the same time: linear longitudinal and radial in the plane of rotation. To simulate lateral sliding or skidding, it will be sufficient to use the drive of the transverse movement of the operator's cab. Accordingly, to develop basic driving skills at the initial stage of training and during their subsequent improvement or correction, it is enough to provide five degrees of freedom of a dynamic platform, which will take into account the perception of basic stimuli by a person in a confined space.
Keywords: combat tracked vehicle, mechanic-driver, dynamic platform, degrees of freedom, pitch, spatial displacements, simulator, training.


ne of the unchangeable processes in the education of our children is the need to move children between and among various programs. As children move from preschool programs to school-age programs, the expectations of teachers change. Children are expected to work more independently, follow group directions, and attend to their own needs. The transition from an early childhood environment to a school setting can be extremely stressful to families (Fowler, Chandler, Johnson, & Stella, 1988; Healy, Keesee, & Smith, 1989). In an effort to alleviate this stress, preparing the child and family for these changes


ABSTRACT: Despite significant clinical, histologic, immunopathologic and other differences between typical cases of dermatitis herpetiformis (DH) and bullous pemphigoid (BP), the differential diagnosis may be difficult.


The role of museum director is increasingly discussed and reported inside and outside the museum community. Turnover grows as museum missions expand and funding sources and amounts decrease. Finding a new director who will be effective when confronted by these pressures requires a realistic assessment by the searching institution of the job to be done. That realistic assessment requires recognition — not necessarily agreement — by both staff and trustees of what the problems and priorities are. There is no perfect director. But there are effective directors. This essay addresses some of the issues facing boards, staffs, search firms, and candidates — as seen from the limited perspective of one person.

Leduc K., Bourassa V., Asselin E., Leclerc P., Lafond J., and Reyes-Moreno C. It is well established that syncytium formation involves the fusion of mononucleated trophoblasts into a multinucleated structure and the secretion of hormonal factors such as the human chorionic gonadotrophin (hCG). These morphological and biochemical changes are regulated by a plethora of ligands which, upon binding to specific receptors, triggers the activation of many signaling pathways such as janus (...)

Abstract
Doing good toward human beings is something that must be done as social beings in order to create a peaceful life in society. Being a very important thing to do good to the wife, this is often neglected by husbands. Doing good to the wife is an absolute obligation for the husband by doing good will create peace in the family and raise peace-loving generations. In this study, we will discuss the study of takhrij hadith about doing good to the wife and others, which will examine partially, namely how the reliability of the narrators, the connection of sanad, whether or not the hadith is valid, converts (note whether or not) the hadith is valid and examines the hadith in detail. Simultaneously, this study uses the Gamee Al-Kaleem application version 4.5. an application designed for  Takhrij Al-Hadith.Based on the research's finding, it is concluded that first, the narrator Sufyan Al Tsauri is a Tsiqah narrator. Second, the hadiths studied are in the Shohihul Al-isnad category. Third, this hadith about doing good to family and others can be concluded to be in the Sahih al-Matan category. Fourth, the existence of this hadith and other hadiths are in one corridor to support each other. Fifth,  the hadith about doing good to family and other people under study does not contain illat which can make it rejected by the Aqli argument. Sixth, by partial research, this hadith is shohihul al-hadith/shohih lidzatihi. Seventh, the simultaneous research shows that this hadith is ahad ghorib.

Studies of apologia have typically focused on powerful individuals and institutions responding to charges from equally powerful opponents, the struggles between elites and counter‐elites. This essay argues that apologia may also be a tactic of resistance as subordinate groups answer the charges of superordinate groups. An examination of the American Nursing Association's response to research indicating many nurses had participated in assisted suicides suggests tactical apologias blend various postures of apologia and seek to confuse rather than dispel the accusatory situation.

Abstract This study employed data envelopment analysis with a two-stage bootstrapping technique to analyze cost efficiency in aquaculture using the case of intensive white-leg shrimp farming in Phu Yen province, Vietnam. By adopting the bootstrap procedure in the first stage, the bias-corrected point estimate of cost efficiency was 0.604 with the lower limit of 0.541 and the upper limit of 0.687 at the 95% confidence interval. Moreover, allocative inefficiency, implying the inappropriateness of input mixes—given their respective prices—was found to be the primary cause of cost inefficiency in this aquaculture. The result from bootstrap truncated regression in the second stage suggested that lower input levels of chemicals/drugs and fingerlings and higher input levels of feed used per ha may help to increase the cost-efficiency of shrimp farming. Policies for better access to formal credit are very important in improving cost efficiency in this aquaculture.


- Within the CERMISO INCDMTM Bucharest center, the study of drones requires, among other processing equipment, the use of a high-volume industrial plastic 3D printer. This is the reason why the center was equipped with a JCR 1000 Dual printer with a 1000 x 600 x 600 mm printing volume (insulated and heat-controlled), two printheads, closed enclosure and heat-controlled bed. In the period of about two years since the acquisition of this industrial equipment, we have performed tests, trials and research on this model of 3D printer, so we have reached a series of problems that can be solves for a more safe and precise operation. The problems and the related solutions found are presented in this paper. There are 5 sensitive areas that affect working with this equipment: Given our rich experience with such printers, the paper will present a number of viable solutions to these problems. These proposals are made in such a way as to require a minimum of investment and effort.


Focusing on the problems of target deformation, occlusion, background interference and rotation, a robust video tracking method is proposed in this paper, which is based on the superpixels and dynamic graph matching. Firstly, to make the superpixels edge fit better and structure tighter, the local gradient feature is fused into the simple linear iterative clustering (SLIC) method. Secondly, the candidate target superpixels set is generated by Graph Cuts and to obtain more accurate foreground superpixels set, the LASVM classification results are fused into the Graph Cuts energy function. Thirdly, in order to make the proposed tracker more robust, the color local entropy is fused into the diagonal elements of the affinity matrix. Experiment results show that the proposed algorithm has strong robustness and better tracking accuracy.


Properties of adenosine deaminase from thrombocytes of healthy persons and of patients with chronic myeloleukosis were studied in presence of various structural analogues of purines and metal ions as well as at various temperature. Catalytic properties of the enzyme in thrombocytes of patients with chronic myeloleukosis were distinct from those of thrombocytes of healthy donors. These differences in the enzymatic properties (contrary to standard estimation of the enzyme activity) might be used both as a criterion of adenosine deaminase anomalies and for detection of the initial steps of the disease.


Rats were fed on a diet containing cholesterol (Chol) at a level corresponding to the standard Chol intake in humans, and the influence of heat-moisture-treated high-amylose cornstarch (HHA) on their serum Chol level was investigated. HHA decreased the serum level of Chol in rats fed on the diet containing 0.1% Chol, which corresponds to a Chol intake in humans of 800 mg/d, although the liver levels of Chol increased in these rats. HHA did not influence the fecal excretion of Chol/bile acids. It is possible that the decrease in serum Chol level in the rats fed on the high-Chol diet can be attributed to the promotion of Chol uptake in the liver.

High efficiency CdTe solar cells typically use oxygenated CdS (CdS:O) window layers. We synthesize CdS:O window layers at room temperature (RT) and 270 °C using reactive sputtering. The band gaps of CdS:O layers deposited at RT increase when O2/(O2 + Ar) ratios in the deposition chamber increase. On the other hand, the band gaps of CdS:O layers deposited at 270 °C decrease as the O2/(O2 + Ar) ratios increase. Interestingly, however, our high temperature closed-space sublimation (CSS) processed CdTe solar cells using CdS:O window layers deposited at RT and 270 °C exhibit very similar cell performance, including similar short-circuit current densities. To understand the underlying reasons, CdS:O thin films deposited at RT and 270 °C are annealed at temperatures that simulate the CSS process of CdTe deposition. X-ray diffraction, atomic force microscopy, and UV-visible light absorption spectroscopy characterization of the annealed films reveals that the CdS:O films deposited at RT undergo grain regrowth and/or crystallization and exhibit reduced band gaps after the annealing. Our results suggest that CdS:O thin films deposited at RT and 270 °C should exhibit similar optical properties after the deposition of CdTe layers, explaining the similar cell performance.


Shadows of Ethics: Criticism and the Just Society Geoffrey Galt Harpham. Durham, North Carolina: Duke University Press, 1999. $49.95.Shadows of Ethics, Geoffrey Galt Harpham's examination of post-formalist literary theory and the ethical dimensions of these theories is by far the most accessible meta-theoretical work I have ever encountered. That being said, Harpham clearly expects his audience to be highly intelligent, educated, and familiar with both modern thinkers such as Kant, Freud, and Nietzsche, and post-formalist ones such as Derrida. Herpham has done vast amounts of research into both modern and more recent critics (philosophical and psychological as well as literary) and expects his readers to keep up not only with their ideas, but his own, which are dense, complex, and legion. Yet both his explanations of various critical theorists and their concepts, as well as his arguments about their theories, are not only well and intelligently written, but completely comprehensible. And Harpham does not bore his audience either. Despite the weighty subject matter, he finds room for both wit and humor.In Shadows of Ethics, Harpham ultimately argues that, as a reaction to formalism, post-modern and contemporary thinkers have tried to eliminate ethics from their theories, their discussions, and their analyses. Yet, as Harpham shows, these theorists have unwittingly included ethics even in their attempts to exclude it. These critics have, moreover, tripped themselves up in their own denials occasionally. Criticism, according to Harpham, has a double standard:One of the most remarkable facts to emerge from the history of literary criticism is that while critics in this century have, with almost no exceptions, been bent on a single project, the destruction of the Romantic notion that literature speaks a timeless truth-with some schools arguing against the timelessness and others against the truthfulness-virtually all schools of criticism have presumed and often explicitly claimed such truthfulness for themselves. (Harpham 44)Harpham discovers many such contradictions in the works of critics: Derrida's very ethical deconstructive analysis of de Man's anti-Semitic writings; the similarity in Foucault's work to Enlightenment thought despite his persistent resistance to Kant; and parallels between Foucault's ideas about power and Chomsky's. Finally, Harpham argues in his concluding chapter that literary critics and other thinkers really should stop arguing and criticizing ideas, institutions, and states of affairs without offering solutions. Rather, they should embrace what cannot be reduced to pure thought: real life, and real circumstances that do not have cleanly defined solutions (258).Despite the subtitle and the intention of Harpham's argument, however, ethics seems to get lost in the intelligent and entertaining chapters. …

Rejects generated in mining projects usually do not have associated economic value. Most of the ore beneficiation processes occur by wet process with a higher fraction of water and ultrafine granulometry, which makes it difficult to dispose of these wastes. In 2013, studies with new tailings treatment and filtering technologies were initiated with the objective of eliminating the disposal of the residue generated in the industrial process to wet in dams. In this context, we tried to evaluate an alternative for the dewatering of the sludge and the tailings, aiming at their disposal in piles. Essentially, we sought to consolidate the application of the high-pressure filtration technology for the effluent dewatering, in order to allow its transport and its disposal in a sustainable way. The studies performed in a pilot filter showed good performance and allowed the industrial implantation. The studies and geotechnical indications of composite tailings (flotation and sludge) make it possible to dispose of the tailings in piles due to their better values of humidity, which allows them to be safely stacked.
