Novel coronary Au@Bi nanospheres (NSs) are simply synthesized by sparkling gold nanoparticles (Au NPs) on the surface of bismuth (Bi) NSs and successfully used as highly impedance‐sensitive immunosensing platform to develop a new label‐free electrochemical immunosensor for the detection of carcinoembryonic antigen (CEA). Firstly, Bi NSs are prepared by one‐pot hydrothermal method, showing uniform sphere morphology with a dense oxide film formed outside Bi NSs due to the easy oxidation of Bi in the air. The oxide film significantly hinders the transmission of electrons and effectively improves the sensitivity of the proposed electrochemical impedance immunosensor. The surface functionalization of Bi NSs with Au NPs enhances the biocompatibility, stability, as well as active surface area of the produced Au@Bi NSs, preferable for the efficient loading of antibody molecules. The electrochemical impedance spectroscopy (EIS) is selected as the optical technique to measure CEA with the constructed immunosensor based on Au@Bi NSs. Because of the excellent impedance‐responsive performance, this new immunosensor displays highly sensitive detection toward CEA in a linear range of 50 fg mL−1–100 ng mL−1 with an extremely low detection limit of 9.83 fg mL−1 and could be potentially used in early clinical detection of cancer.


In conventional "flow control valve and travel switch" control strategy, relative height difference between multiple cylinders only reach accuracy of centimetre grade, which can't meet synchronous control accuracy requirements of many engineering. In order to improve multiple cylinders synchronous accuracy of the hydraulic lifting system, this paper takes a hydraulic lifting system as basis, which studies PID closed loop control system using electro-hydraulic proportional valve and high-precision displacement accuracy sensor, and the synchronous accuracy of 4 cylinders hydraulic lifting system is improved to millimetre grade.

Measurement of the anthropometric parameters, estimation of trochanter index (TI), definition of the organism constitutional type age-related evolution by V.G. Shtefko (1929) and S.G. Vasilchenko (1990) as well as the study of serum total cholesterol have been made on the men of a second adulthood. Investigation showed that 39% of men had trochanter index (TI) more than 2,04. Indicator of the body length slightly decreases with increasing TI. The body mass index does not depend on the value of TI and is within 75-90 percentiles. The body mass index value does not depend on the trochanter index. The trend of increasing the body fat mass and relative fat mass (%) has been revealed within the group of men with low (1,92-1,94) and high values of trochanter index (> 2,04). High levels of serum total cholesterol has been observed within the group of men with high values of trochanter index (more than 2,04) in comparison with men, that had the average trochanter index values. Negative correlation (r = -0,249) between indicators of the serum total cholesterol level and lean body mass is shown as the trend (p = 0,203).

Mantle cell lymphoma (MCL) rarely involves thyroid gland. Positron emission tomography–computed tomography (PET‐CT) may be critical in identifying thyroid involvement by MCL and pursuing further work up of the suspicious thyroid lesions, irrespective of the thyroid function tests.


Wireless Sensor Networks (WSN)s and Artificial Intelligence are the important emerging technologies of computer science. Wireless Sensor Networks keeps track of the dynamic environment that changes rapidly and artificial intelligence is making the machines intelligence. The wireless sensor networks are consisting of several sensor nodes which are designed with the little memory, smaller power and less strength of communication among neighbor nodes. The dynamic behavior of an environment is due to the external conditions or WSN system designers. To adjust to these varying conditions, sensor networks are implemented based on the artificial intelligence techniques. Artificial intelligence also incorporates the utilization of the available resources to the extent by minimizing the energy consumption of sensor nodes. In the present paper, it is involved with the address of common problems associated with the sensor nodes and how it is incorporated by applying Artificial Intelligence.


Abstract A new thermodynamic model was developed to calculate the onset of flocculation in crude oil systems similarly to the liquid-liquid equilibrium of polymer solutions. The key concept of the model is that asphaltene self-association leads to a polydisperse system of associates characterized by a size distribution function. Using continuous thermodynamics the mass action law is applied to the association equilibrium and an analytical expression for the size distribution function is derived. In contrast to polymer thermodynamics this distribution function depends on temperature, pressure, and concentration. For modeling the high pressure equilibrium the Sako-Wu-Prausnitz equation of state is applied. The model was tested on existing flocculation data for three systems of the type methane + i-octane + maltene + asphaltene with crude oils of different asphaltene contents. The amount of precipitant necessary to provoke flocculation was calculated in good agreement with the experimental data for all three systems up to a pressure of 15 MPa.


The purpose of this study was to investigate a mentor-teacher qualification standard to support professional development for beginning secondary science teachers. The participants were four mentee teachers and four mentor-teachers. The relationship between the development of beginning science teachers teaching practice and characteristics of the mentoring and interactions was investigated by analyzing conversations between mentor and mentee teachers during the collaborative mentoring. Three mentoring conversation records and transcripts during mentoring program were collected. An analytical framework of mentoring conversations was used in the analysis of mentoring conversations and RTOP was used for lesson analysis to determine the development of teaching practice. The results show that the types of interactions during mentoring varied according to the mentoring teams. Mentors who encouraged reflective thinking induced a higher level of teaching in their mentees. The mentor qualification standard was determined from the relationship between the characteristics of the interaction and the improvement in beginning teacher's teaching practice. To be an effective mentor, the mentor should be able to 1) lead the interaction in a manner that encourages the exchange of opinions, 2) induce reflective thinking and ability to achieve reflective practice following reflective thinking, 3) provide clear explanations and suggest detailed methods, 4) lead conversations that encourage reflective thinking with questions about teaching supported techniques.


It has been shown that changes of intracellular levels of S-adenosylmethionine (SAM) are related to the well beings of cells and organisms. The fluctuation of SAM level is cause by imbalance between SAM synthesis and metabolic pathways (methylation, transsulfuration and aminiopropylation) or degradation. S-adenosylmethionine biosynthesis is strictly and solely dependent on the activity of Methionine Adenosyltransferase (MAT, E.C.184.108.40.206), also known as S-adenosylmethionine synthetase. The methionine adenosyltransferase is encoded by two genes, MAT1A and MAT2A, encode for two homologous MAT catalytic subunits, α1 and α2. MAT1A is expressed in normal liver, and it encodes the α1 subunit found in two native MAT isozymes, which are either a dimer (MAT III) or tetramer (MAT I) of this single subunit. MAT2A encodes for a catalytic subunit (α2) found in a native MAT isozyme (MAT II), which is associated with a regulatory subunit (β) in encoded by MATA2B gene. MAT1A is expressed mostly in the adult normal hepatocytes, whereas MAT2A is widely distributed, of which mainly investigated are among highly proliferating liver cells, such as fetal liver and liver cancer cells. Except for parasites that rely on host for living, cells from all organisms have methionine adenyltransferase. MAT genes have been found to be exceptionally conserved throughout evolution.


A piano key weir (PKW), a new type of weir aiming to increase the discharge capacity of an existing dam, was recently designed. Despite a large body of research in this field, only a few studies were conducted on A-type triangular piano key weirs (TPKW) in straight channels. In this context, this present research sought to study the flow regime, stage–discharge relationship, and discharge coefficient. Experiments were carried out using nine TPKW models and three linear weirs (LW) as the control weirs. The results indicated that the triangular piano key weirs are capable of passing a higher discharge in similar laboratory conditions compared to linear key weirs due to their longer length. For a given h/P ratio (h is the water head over the weir crest, and P is the weir height) and constant length (Le), an increase in the weir height from 0.07 m to 0.15 m decreases the discharge coefficient by approximately 20%. From sensitivity analysis, the most influential parameters for the tested TPKW models are the h/Le dimensionless ratio, followed by the P/Le and Fr. Moreover, the discharge coefficient has a reverse trend when the dimensionless parameters h/P, h/Le, and Froude number are increased. However, with decreasing h/Le, the discharge coefficient of TPKW tends to that of a broad-crested weir because of local submergence. It is expected that the results obtained will be a reference for researchers who work in this field.


The objective of this study is to investigate the determinants on affective commitment in the Chinese hotel industry. This paper proposes a research model that consists of five antecedents (i.e., self-emotional appraisal, others" emotional appraisal, regulation of emotion, use of emotion, and followers' positive affect) leading to affective commitment in the context of Chinese hotels. Data were collected from 300 respondents working in the hotel industry in Shandong, China. This study used SmartPLS 2.0 (Ringle et al., 2005) and Anderson and Gerbing (1998)'s a two-step approach to test research hypotheses. The present study assessed convergent validity and discriminant validity of the measurement model in a preparatory step. Path analysis was used to test hypotheses in a second step. Results showed that three antecedent factors (i.e., self-emotional appraisal, regulation of emotion, and use of emotion), except for others" emotional appraisal, had significant impacts on followers' positive affect, which leads to affective commitment. From the research findings, useful practical implications for Chinese hotel managers and suggestions for future research are discussed in this study.


The study examines Germano-Anglo colonial towns in Cameroon to determine factors accounting for the scarcity of infrastructure as well as streets and places with Eurocentric names. Using primary and secondary data, it demonstrates that the lack of infrastructure in the polity is a function of negligence by colonial and post-colonial authorities. With few pieces of public infrastructure, the authorities have had few streets and places to attribute names from Eurocentric lexical dictionaries. These findings contribute to knowledge of the relative impact of endogenous and exogenous factors on toponymic traditions as well as inter-country differentials in African countries' development profiles.


How, as a sub-set of maritime security, can piracy studies contribute with conceptual insights of relevance to the field of international security governance and international politics more broadly? To answer this question the article examines, with reference to critical intervention studies, how responses to Somali piracy have had constitutive effects, notably 'back onto' the intervening actors themselves. More specifically, three themes are examined: regulation (law), structures (institutions) and practices (actors), each of which highlights a distinct sense of contingency, which both characterizes contemporary security governance at sea and makes 'the maritime' an interesting domain for the study of constitutive effects related to the making of intervention actors. In light of this, the article argues that studying 'the maritime' can offer conceptual insights to the constitutive effects of counter-piracy interventions that may prove relevant to broader debates about governance and security in a changing world order.


In this paper we have studied the existence and the nature of long-range relations between the main indices of three European stock markets: in Frankfurt, Vienna and Warsaw. The first two of them are developed markets, while the last one is seen as an emerging market. On the basis of daily data from the period 2003–2014 we analysed the I(1)/I(0) co-integration of market indices. The results of this commonly applied technique are compared with the results of the more flexible fractional co-integration analysis. keywords: cointegration; fractional cointegration; stock markets; emerging markets


Nonlinear mapping is an essential and common demand in online systems, such as sensor systems and mobile phones. Accelerating nonlinear mapping will directly speed up online systems. Previously the authors of this paper proposed a Dendrite Net (DD) with enormously lower time complexity than the existing nonlinear mapping algorithms; however, there still are redundant calculations in DD. This paper presents a DD with an acceleration module (AC) to accelerate nonlinear mapping further. We conduct three experiments to verify whether DD with AC has lower time complexity while retaining DD's nonlinear mapping properties and system identification properties: The first experiment is the precision and identification of unary nonlinear mapping, reflecting the calculation performance using DD with AC for basic functions in online systems. The second experiment is the mapping precision and identification of the multi-input nonlinear system, reflecting the performance for designing online systems via DD with AC. Finally, this paper compares the time complexity of DD and DD with AC and analyzes the theoretical reasons through repeated experiments. Results: DD with AC retains DD's excellent mapping and identification properties and has lower time complexity. Significance: DD with AC can be used for most engineering systems, such as sensor systems, and will speed up computation in these online systems.

Although rural female poverty is vital component of the China's poverty,
it doesn't receive enough attentions from government and scholar. In order to draw
a better interpretation of rural female poverty and gender inequality that allowing
more targeted poverty reduction policies and actions, this thesis examines the
gender inequality and within-group differences in female poverty from a wide range
of poverty, including income poverty, capability deprivation of health, mental
health, education, social relation, political participation, paid work and inequality
of domestic work. The result shows that there is a significant gender inequality in
income, education, political participation, paid work and domestic work. In addition,
among all the rural female, those who identified as ethnic minority, older than 65
years old and employed in agricultural sector are most like to suffer various
dimensions of poverty.


Electrokinetics (EK) is an emerging remediation technology for the in situ removal of heavy metals, volatile organic compounds, and radionuclides from soils and sediments. Naval Air Weapons Station Point Mugu, California will host an EK technology demonstration. The demonstration will consist of installing and operating an EK system, which is engineered to remove cadmium and chromium from former electroplating waste lagoons. The selected site is adjacent to and encroaches on an environmentally sensitive salt marsh are for a federally protected wildlife. The electrokinetic process will be used to mobilize and extract heavy metals from the metals‐contaminated soil by applying a low amperage direct current across an array of electrodes placed in the contaminated soil. The demonstration will focus on the effectiveness of the EK process for removing heavy metals from the tidal marsh area. The EK demonstration will be used to collect cost‐effective data necessary to address both the technical and economic feasibility of using this technology in areas where soils are porous, water is brackish, and the system is susceptible to tidal influences.


The mathematical model for analyzing the transmission dynamics of HIV/AIDS epidemic with treatment is studied by considering the three latent compartments for slow, medium and fast progresses of developing the AIDS. By constructing the system of differential equations for the different population groups namely susceptible, three types of latent individuals, symptomatic stage group and full blown AIDS individuals, the mathematical analysis is carried out in order to understand the dynamics of disease spread. By determining the basic reproduction number (R0), the model examines the two equilibrium points (i) the disease free equilibrium and (ii) the endemic equilibrium. It is established that if R0 <1, the disease free equilibrium is locally and globally asymptotically stable. The stability of endemic equilibrium has also been discussed.


A noisy index coding problem (ICP) over additive white Gaussian noise (AWGN) and Rayleigh fading channels is studied. First, a single-input single-output AWGN broadcast channel is considered. For a chosen index code and an arbitrary mapping (of broadcast vectors to phase-shift keying (PSK) signal points), a decision rule for the maximum-likelihood (ML) decoder is derived. The message error performance of a receiver at high signal-to-noise ratio (SNR) is characterized by a parameter called <italic>PSK-index coding gain (PSK-ICG)</italic>. The PSK-ICG of a receiver is determined by a metric called <italic>minimum inter-set distance</italic>. For a given ICP with an order of priority among the receivers, and a chosen <inline-formula><tex-math notation="LaTeX">$2^N$</tex-math> </inline-formula>-PSK constellation, an algorithm to find <italic>(index code, mapping)</italic> pairs, each of which gives the best performance in terms of PSK-ICG of the receivers, is proposed. No other pair of index code (of length <inline-formula><tex-math notation="LaTeX">$N$</tex-math></inline-formula> with <inline-formula> <tex-math notation="LaTeX">$2^N$</tex-math></inline-formula> broadcast vectors) and mapping can give a better PSK-ICG for the highest priority receiver. Also, given that the highest priority receiver achieves its best performance, the next highest priority receiver achieves its maximum gain possible and so on in the specified order of priority. Next, the noisy ICP over a multiple-input multiple-output (MIMO) Rayleigh fading channel is considered. The receivers are equipped with a single antenna and a server with two antennas. To obtain the diversity gain along with the coding gain, a MIMO scheme that employs space-time coding along with index coded PSK modulation is proposed. For a chosen index code, an arbitrary mapping (of broadcast vectors to PSK signal points), and a <inline-formula> <tex-math notation="LaTeX">$2 \times 1$</tex-math></inline-formula> MIMO system employing Alamouti code, we derive a decision rule for the ML decoding. We show that for the best coding gain at high SNR, the mapping must maximize the minimum inter-set distance.


To derive range to a moving vehicle for surveillance and navigation purposes, the phase delays in sets of sinusoidal tones may be measured using synchronous satellites for signal relay. Problems of rapid acquisition and measurement occur in multiple-access systems with large numbers of users. This paper describes the selection and processing of an orthogonal tone set which possesses several useful features, particularly the elimination of the requirement for separation of the tones by filtering before measurement. The technique is being used for the Position Location and Aircraft Communications Experiment (PLACE), to be conducted following the launch of the NASA ATS-F satellite. Preliminary experiments have already tested the methods. This paper also describes a simplified, digital technique which performs correlation against the hard-limited signal plus noise and which does not degrade the ranging accuracy. The results of digital simulation are presented. I. Introduction THIS paper describes a simple technique for measuring the range to a moving vehicle (e.g., aircraft or marine user) in a proposed navigation system using synchronous satellites as signal relays. In this particular application, which involves the surveillance of a moving vehicle, a measurement is made of the two way range to the vehicle via the satellite relay. The proposed measuring technique derives this range from the phase delays occurring in a set« of sinusoidal tones transmitted over the two-way path and received back at the originating station. For distance measuring accuracy a high tone frequency is required, and successively lower frequency tones are used to resolve the multiple wavelength ambiguities resulting from use of the high frequency tone. It may be shown that for a relay satellite in synchronous orbit, the tone frequency required to resolve the largest possible ambiguity is about 25 Hz. This will allow the determination of the maximum differential between the closest and farthest possible ranges of more than 3191 naut miles. In one concept of a practical system, the range tones are received continuously by all users but are transponded sequentially in short bursts following a predetermined sequence as shown in Fig. 1 (This shows one satellite of the two required for a position fix). To accommodate a large number of vehicles the length of each tone burst may be less than 0.5 sec, and phase measurements by the ground station must be made for each vehicle in this time.


A visit by the author the director of the Arizona Family Planning council to American Samoas Title X program confirmed the basic health benefits of family planning the universality of problems faced by family planning programs and the value of coordination in maximizing limited resources. American Samoa faces severe cultural obstacles to the use of birth control. The family is the basic unit of society and all 3 major religions on the island--Congressional Christian Church Roman Catholicism and the Church of Jesus Christ of Latter Day Saints-- have positions against contraceptive use. In the 1970s however public health officials became concerned with the harmful health effects to both women and infants of a lack of birth spacing. The challenge was to convince the public that family planning methods could be beneficial to families. An early public education and media campaign conducted by the Department of Health that compared birth spacing to the spacing of coconut palms to produce stronger healthier trees was particularly effective. The national family planning program is administered by a nurse practitioner and an average of 150 acceptors are served each month. American Samoans expressed a preference for the IUD but this device can no longer be obtained with Title X funds. At present the pill is the most common method. Health education outreach and home visiting by public health nurses are established components of the national family planning program.

This paper presents a variable admittance controller for eliminating instability in physical Human-Robot Interaction. In order to predict the instability, human hand stiffness is estimated in real time by modeling the level of muscle co-contraction of the human's arms. A modified time-domain vibration index is then proposed based on the forces applied by the operator on the robot. The virtual damping coefficient in admittance controller is adjusted according to the human hand stiffness and the vibration index to ensure both the performance and stability of the interaction system. The proposed system is evaluated on an experimental set-up using an UR10 robot and the results demonstrate significant improvement in stable and low-effort cooperation.

The resolution of remote sensing images has increased with the maturation of satellite technology. Ship detection technology based on remote sensing images makes it possible to monitor a large range and far sea area, which can greatly enrich the monitoring means of maritime departments. In this paper, we conducted research on small target detection and resistance to complex background interference. First, a ship dataset with four types of targets (aircraft carriers, warships, merchant ships and submarines) is constructed, and experiments are conducted on the dataset using the object detection algorithm YOLOv4. The Kmeans++ clustering algorithm is used for a priori frame selection, and the migration learning method is used to enhance the detection effect of the YOLOv4. Second, the model is improved to address the problems of missed detection of small ships and difficulty in resisting background interference: the RFB_s (Receptive Field Block) with dilated convolution is introduced instead of the SPP (Spatial Pyramid Pooling) to enlarge the receptive field and improve the detection of small targets; the attention mechanism CBAM (Convolutional Block Attention Module) is added to adjust the weights of different features to highlight salient features useful for ship detection task, which improve the detection performance of small ships and improve the model's ability to resist complex background. Compared to YOLOv4, our proposed model achieved a large improvement in mAP (mean Average Precision) from 77.66% to 91.40%.

The present paper intends to study the effect of progressive muscle relaxation on executives with coronary heart disease. The main objectives of the study were to compare the job stress level, coping strategies and personality type of public sector senior executives with and without CHD. The Sample for the study consisted of 70 senior executives from B.H.E.L, Bhopal. To have a comparative study of the variables, matched group design was opted. The findings reveal that there is significant difference in the stress levels, coping strategies and personality type among executives with and without CHD. Executives with CHD had more job stress, ineffective coping strategies and type A personality in comparison to the executives without CHD. Further, the practice of progressive muscle relaxation brings significant reduction in the stress levels of CHD patients.


The unexpected resistance reduction effect of double-trench SiC MOSFETs under repetitive avalanche stress is investigated in this work. After enduring repetitive avalanche stress, the ON-state drain-source resistance (Rdson) of the device decreases. With the help of TCAD simulations, the dominant mechanism is proved to be the injection of positive charges into the gate trench bottom oxide, which is almost irreversible under zero-voltage bias condition at room temperature. For the injected positive charges attract extra electrons just beneath the gate trench bottom, where the carriers pass through under ON state, the resistivity there is reduced, improving the conduction capability of the device. Moreover, an optimization method is proposed. Since the impact ionization rate (I.I.) and the vertical oxide electric field (E⊥) along the gate trench bottom oxide interface contribute to the injection of positive charges, it is recommended to make the bottom oxide thicker to suppress this effect.


European Romanticism gave rise to a powerful discourse equating genres to constrictive rules and forms that great art should transcend; and yet without the categories and intertextual references we hold in our minds, "music" would be meaningless noise. This book teases out that paradox, charting the workings and legacies of Romantic artistic values such as originality and anti-commercialism in relation to musical genre. Genre's persistent power was amplified by music's inevitably practical social, spatial, and institutional frames. Furthermore, starting in the nineteenth century, all music, even the most anti-commercial, was stamped by its relationship to the marketplace, entrenching associations between genres and target publics (whether based on ideas of nation, gender, class, or subtler aspects of identity). These newly strengthened correlations made genre, if anything, more potent rather than less, despite Romantic claims. In case studies from across nineteenth-century Europe engaging with canonical music by Bizet, Chopin, Verdi, Wagner, and Brahms, alongside representative genres such as opéra-comique and the piano ballade, Gelbart explores the processes through which composers, performers, critics, and listeners gave sounds, and themselves, a sense of belonging. He examines genre vocabulary and discourse, the force of generic titles, how avant-garde music is absorbed through and into familiar categories, and how interpretation can be bolstered or undercut by genre agreements. Even in a modern world where transcription and sound recording can take any music into an infinite array of new spatial and social situations, we are still locked in the Romantics' ambivalent tussle with genre.


The goal of this article is to train deep neural networks that accelerate useful adaptive learning rate optimization algorithms such as AdaGrad, RMSProp, Adam, and AMSGrad. To reach this goal, we devise an iterative algorithm combining the existing adaptive learning rate optimization algorithms with conjugate gradient-like methods, which are useful for constrained optimization. Convergence analyses show that the proposed algorithm with a small constant learning rate approximates a stationary point of a nonconvex optimization problem in deep learning. Furthermore, it is shown that the proposed algorithm with diminishing learning rates converges to a stationary point of the nonconvex optimization problem. The convergence and performance of the algorithm are demonstrated through numerical comparisons with the existing adaptive learning rate optimization algorithms for image and text classification. The numerical results show that the proposed algorithm with a constant learning rate is superior for training neural networks.


New techniques to generate and culture embryo-like structures from stem cells require a more fine-grained distinction of potential to define the moral status of these structures.


High resolution ultrasound exam was performed to measure the flow-mediated (endothelium-dependent)and glycerylnitrate-induced (endothelium-nondependent)brachial arterial dilation in impaired glucose tolerant patients. The endothelium-dependent arterial dilation in IGT group (n=28)was significantly lower than that in control (n=25)(P0.05), and endothelium-independent arterial dilation in both groups were not significantly different (P0.05).


In this work, polycrystalline silicon (poly‐Si) thin films were fabricated by aluminum induced crystallization (AIC) technique. SiNx, deposited as a function of NH3/SiH4 ratio, and AZO (Al‐doped ZnO) films on glass were used as a buffer layer between glass and Si film. The effect of buffer layer content on the crystallinity of poly‐Si thin films was studied by Raman analysis which shows that fully crystallization without stress was achieved for all samples. Moreover, the preferred crystalline orientation and crystallite size of films were deduced by X‐ray diffraction (XRD) analysis. The preferred orientation is <100> as independent from the buffer layer content while the crystallite sizes increase up to 48.5 nm by increasing the amount of SiH4. The electrical properties of the films were carried out by four point probe and current–voltage (I–V) analysis. Both techniques demonstrated that the resistivity of the SiNx‐based samples is around 0.1 Ωcm. The grain size analysis was accomplished by electron back scattering diffraction (EBSD) measurements. The grain size up to 25 µm was achieved as observed from EBSD images. The results show that the fabrication parameters of SiNx and AZO buffer layers have the great effects on the crystallography of poly‐Si films.


The role of teaching English as a second language will be related to a refugee community in Australia. Research demonstrates that second language acquisition has had major impacts on the traditional family, social, and cultural leadership structure of the Hmong, including first language attrition among second generation immigrants. The results of education will be considered within a social and ethnographic context, as well as situated within the troubling framework of language and power. Ultimately, it will be argued that although learning English does assist the integration of ethnic communities in Australia, there can be a destructive social and cultural price to pay for these communities.


To investigate the influence of boric anhydride (B2O3) on mechanical properties of nylon 6, tensile, hardness and impact test were carried out. Average tensile strength along with percentage elongation and modulus of elasticity has been calculated and plotted in this paper. Rockwell hardness and Izod impact tests were carried out to identify the hardness and toughness of materials. Boric anhydride used in this research was limited to less than 10 wt% of nylon 6 matrix material and was 2 wt%, 4 wt% and 8 wt%. Abrasion resistance of pure nylon 6 and composites was measured as weight loss due to abrasion. For the characterization of nylon 6 and its composites, Thermo-gravimetric analysis (TGA) and x-ray diffraction (XRD) were carried out. In results, it was found that the boric anhydride reinforcement increased the tensile strength and abrasion resistance when used up to 2 wt% in the nylon 6 matrix. Hardness found to be continually increased as the boric anhydride reinforcement percentage increased. The crystallinity of nylon 6 was little affected due to fillers and was found minimum for the 4 wt% boric anhydride reinforced nylon 6 composites. It was also found that the elastic modulus, Rockwell hardness and tensile strength, abrasion resistance show good correlations which are discussed in the discussion section.


Phalsa (Grewia subinaequalisD.C.) which is also known as star apple is a subtropical fruit of India. It is good crop for arid and semi arid regions because of hardy nature and capacity to tolerate high temperature. It bears small berry like fruits of deep redish brown colour in cluster in axil of leaves of the young shoots. Ripe fruits are subacidic and good source of vitamin A and C, and also fair source of phosphorus and iron. The fruits are used for making excellent juice and squash. The experiment was laid out during January to October 2003 at Main Experiment Station in Factorial Randomized Block Design having seven treatments including three levels of nitrogen (50, 75, 100 g plant -1), two levels of potash (25, 50g plant-1) and absolute control with three replication. The observat ion recorded on various growth, maturity and yield parameter. The significant higher number of shoot plant- 1 , number of fruiting nodes-1, yield plant-1, yield ha-1, was recorded with 75g N plant-1 and 50g K plant-1. The length of shoot and number of leaves shoot-1, fruit set and days taken to fruit maturity increased significantly up to 75g N plant -1 and 25g K plant-1 whereas, fruit drop was lower at 75g N plant-1 and 25g K plant-1. Finally it may be concluded that for better growth, fruit maturity and max imum fruit yield phalsa should be fertilized with 75g N plant -1 and 50g K plant-1.


After nearly 20 years of limited natural recovery following the Gulf War oil spill, surveys were conducted in 2009-2010 to identify where oil has persisted and ecological recovery has been slow along the Arabian Gulf coastline of Saudi Arabia. In 2011-2013, large-scale remediation projects were executed on 3 locations totaling 155 hectares of tidal flats and sand beaches to speed ecological recovery. Targeted remediation techniques were used as tools to meet the following goals: 1) increase suitable habitat for grazers and burrowing infauna; 2) reduce total petroleum hydrocarbon levels; and 3) improve physical processes (drainage) and reduce associated stressors such as ponding. Three principal techniques were developed and utilized along sheltered and moderately exposed tidal flats: 1) tilling of oiled sediments using tines (rake) or disc harrow attachment, followed by manual removal of remaining surface oil; 2) complete physical removal and disposal of the surface or cohesive subsurface oiling layers; and 3) tilling areas contained within berms while flooded to liberate liquid oil that was subsequently recovered by skimming/vacuuming. The first technique was considered appropriate when there was a well-defined gradient between hardened surface oiling and lightly oiled subsurface sediments, within sandy tidal flats, and where sediment conservation was a priority. This technique resulted in 20% additional oiled surface residue cover, which was removed manually. Resulting sediment loss was minimal. Goals 1, 2 and 3 were met. The second technique was preferred when there was a dry cohesive oiled layer either on the surface or beneath a layer of clean sand and where sediment conservation was not a priority. Excavation of oiled sediments resulted in high sediment loss by physical removal; however, goals 1 and 2 were clearly achieved. Additional re-grading including possible sediment replacement was required to achieve goal 3. The third technique was considered the optimal method when there was a high level of subsurface liquid oiling within tidal flats, and if sediment conservation was a priority. Goal 1 was achieved by breaking up surface barriers. To achieve goals 2 and 3, multiple tilling passes were required to liberate and remove liquid oil. Monitoring results show that while oil levels varied across remediated sites, a trend in reduction was common throughout. Short- and long-term ecological responses are being monitored.


In an increasingly competitive environment, it seems to be important to analyze risks in term of quality bound to the different strategies of outsourcing. Indeed, beyond the advantages of the outsourcing at the strategic, financial, organizational and operational level, the outsourcing hides significant dangers which greatly link to the quality of the service. The objective of our research is to analyze risks in term of quality that take the Tunisian firms, in the setting of their textile and clothing activity, when they embark on the outsourcing of one or more of their process, and to examine the effect of this act on the global firm performance.


Today's powertrain engineering is faced with growing customer expectations regarding noise and vibration (NVH) what requires the use of virtual development methods starting already in early phases of the development process. According to the design status progress the simulation model detailing is adapted and stepwise increased. Starting with comparative simple rigid body models in the concept phase decisions regarding engine global parameter like bore, stroke cylinder distance and positioning of balancer shafts take into account also NVH design aspects. In parallel to the ongoing fixation of design parameters the depth of simulation models is increased up to a virtual prototype allowing for NVH prediction of the complete powertrain. At FEV Motorentechnik a hybrid simulation approach based on Finite-Element (FE) and Multi-Body simulation (MBS) was developed. By loading the full powertrain FE model with the NVH relevant excitation forces out of MBS calculation the NVH response, i.e. noise and vibration behavior, is predicted. The powertrain airborne and structure-borne noise simulation can be combined with the individual vehicle NVH transfer paths for prediction of interior noise. This method – called Virtual Vehicle Interior Noise Simulation (V-VINS) allows for target-oriented powertrain development with focus on excellent vehicle noise and vibration behavior.

The transient effects of an 80-year climate change scenario on 56 tree species are evaluated within the regional forested landscape matrix of Wisconsin, Michigan, Illinois, Indiana, and Ohio. The JABOWA-II forest growth model was integrated with a GIS housing several federally-produced databases which were vital for input file development. A 4km{sup 2} resolution enabled high parameter specificity for each of the 54,345 representative 100m{sup 2} plots. Ten iterations of simulated growth response at each site followed model calibration. Changes in relative regional dominance and shifts in population centroids over two periods (1981-2020 and 2020-2060) indicated that most responses were species-specific. Notable among these were the substantial dominance increases of Populus tremuloides and Quercus alba from 1981-2020. Shared response patterns included conifers` centroid shifts to the northwest and overall dominance reductions.


The stratigraphic and structural habitats of many oil and gas pools in carbonate rocks indicate indigenous origin of their hydrocarbons.


PURPOSE: The purpose of this study was to investigate the effect of modified motor developmental intervention on the SCM muscle thickness and the range of motion (ROM) of neck in subjects with congenital muscular torticollis.
METHODS: Thirteen subjects who had congenital muscular torticollis were participated in this study and they were offered the modified motor developmental interventions for 8 weeks by pediatric physical therapist. SCM thickness of affected and non-affected side and ROM of neck rotation were collected between before and after intervention. SCM thickness was measured by using Ultrasound Unit (IU 22, Ultrasound system, Philips, Netherlands) and ROM of neck was measured by using the goniometer (Arthrodial protractor, North coast, USA). Data were represented as means ± SD. Paired t-test was used to determine the effect of interventions on the SCM muscle thickness and neck ROM.
RESULTS: SCM thickness of affected side was significantly decreased after the modified motor developmental interventions and that of non-affected side was generally increased but it was not significantly difference between pre and post interventions. ROM of neck rotation and lateral flexion was significantly increased after interventions.
CONCLUSION: These results suggested that the modified motor developmental interventions could improve the recovery of SCM muscle thickness and neck ROM.


At a time when "out of stock" is rapidly becoming a way of life there is merit in attempting to assess the cost to the business. This article suggests some of the areas which should be considered.


A multistage coevaporation process for the direct growth of Cu2ZnSnS4 (CZTS) thin films without additional atmospheric sulfurization was investigated. To obtain reproducible CZTS films, in situ process monitoring of the film growth was developed by measuring the apparent substrate temperature (Tpyro) using a pyrometer. After CZTS depositions terminated at various endpoints, ex situ characterization of the film properties was performed to clarify the growth mechanism of the films. The results provided clear evidence that CZTS phase formation was significantly delayed via re-evaporation of Sn–S-based compounds in the early part of the first stage, leading to the initial formation of a dominant (CuS + ZnS) structure that coexisted with a small amount of CZTS. CZTS phase formation was then facilitated by the (CuS + ZnS) precursor via a Cu-rich to Cu-poor sequence with an apparent variation in Tpyro during the second stage, and the slightly segregated CuS phase was nearly consumed under (Zn + Sn + S) fluxes. C...


Some of the main weaknesses of the current Computer Supported Collaborative Learning Environments (CSCLE) include using inadequate persistence mechanisms to keep track of the discussions. Moreover, CSCLE also neglect the importance of contextual information to provide the correct cues to interpret sentences. In this light, this paper proposes the creation of a Learning Interaction Memory (LIM) to store the learning interactions occurred in CSCLE. It will be modelled in a multidimensional structure so that interactions can be viewed from different perspectives and could be presented selectively, according to users' needs. The information contained in the LIM can be dynamically adapted to the current situation. This is done to provide better just-in-time feedback for students and teachers.


Abstract— A comparison of the transient absorption spectra from the photolysis of disulfides in solution suggests that C‐S bond breakage is a common primary photolytic process. This process becomes more important as the resulting carbon centered radical is stabilized by increasing alkyl substitution or resonance interaction with an aromatic system. The perthiyl radical product is characterized by λmax?380 nm,ε380?1700 M−1 cm−1 and decays by second order kinetics with k2?3.7×108M−1 s−1 in water.

A post-breakdown resistance of SiO/sub 2/ has been studied as a quantitative monitor to describe the dielectric breakdown characteristics. First, the usefulness of post-breakdown SiO/sub 2/ analysis is discussed on the basis of experimental results. Clear differences between dry and wet oxides or stress polarities are shown in terms of the post-breakdown resistance of SiO/sub 2/ as well as the charge-to-breakdown. Then, the soft- and hard- breakdowns typically observed in sub-10 nm SiO/sub 2/ are discussed qualitatively but statistically. A main point discussed is to consider a time constant in MOS closed circuit including a sample itself just at the dielectric breakdown. The results imply that the intrinsic parasitic effects become more important in modeling and assessment of scaled-down CMOS device reliability.


A descriptive study of 35 surgically treated patients by means of conventional and laparoscopic techniques who presented iatrogenic injuries of the biliary system, was carried out in the General Surgery Service of "Saturnino Lora Torres" Teaching Clinical Surgical Provincial Hospital in Santiago de Cuba, in a 8 year period (2007-2014), with the aim of characterizing them according to some variables of interest and of determining the associated mortality. Among the predominant results there were the female sex and the ages from 35 to 54 years, the produced lesions of the elective videolaparoscopic cholecystectomy for vesicular lithiasis, the clinical forms of presentation the intraabdominal abscess with peritonitis signs and jaundice, diagnosis confirmed by means of the echography. Also, injuries A and C, according to the classification of Strasberg, were those most reiterated and the most common restorative technical procedure was drainage and washing of the abdominal cavity; 88.6% of the patients were discharged alive and 4 female patients died (11.4%) whose cause of death was the septic shock. It could be concluded that the moment of diagnosis for these lesions took place late, and that in spite of the complexity of the surgical repair, there was low mortality.

Ba(Mg1/3Nb2/3)O3 ceramics with suitable microwave dielectric properties for application in wireless communications and information access technologies were studied by far-infrared spectroscopy. Samples with different B-site ordering degrees, obtained by hydrothermal synthesis followed by sintering at various temperatures, were employed in this investigation. The sixteen infrared modes predicted by factor-group analysis were observed and adjusted according to a four-parameter semiquantum model. The dispersion parameters were determined in order to calculate the real part of the dielectric permittivity and the quality factors associated with the dielectric losses in the microwave region. The materials exhibited increasing e0 and Q values up to 1100 °C, increasing more substantially when the temperature attained 1300 °C. The B-site ordering played an important role on this behavior along with the microstructural evolution above 1100 °C (grain growth), which also increased the phonon lifetime and contributed to the Q improvement. Kramers–Kronig analyses were carried out in all experimental data and the contributions of the main optical polar modes to the dielectric and microwave properties were carefully analyzed in order to identify and attribute the Ba–BO3 external mode, the inner modes related to the O–Mg–O and O–Nb–O bending vibrations, and the stretching modes of each MgO6 and NbO6 octahedron.Ba(Mg1/3Nb2/3)O3 ceramics with suitable microwave dielectric properties for application in wireless communications and information access technologies were studied by far-infrared spectroscopy.

The search for weakly interacting massive particles (WIMPs) by direct detection faces an encroaching background due to coherent neutrino-nucleus scattering. For a given WIMP mass the cross section at which neutrinos constitute a dominant background is dependent on the uncertainty on the flux of each neutrino source, principally from the Sun, supernovae or atmospheric cosmic ray collisions. However there are also considerable uncertainties with regard to the astrophysical ingredients of the predicted WIMP signal. Uncertainties in the velocity of the Sun with respect to the Milky Way dark matter halo, the local density of WIMPs, and the shape of the local WIMP speed distribution all have an effect on the expected event rate in direct detection experiments and hence will change the region of the WIMP parameter space for which neutrinos are a significant background. In this work we extend the neutrino floor calculation to account for the uncertainty in the astrophysics dependence of the WIMP signal. We show the effect of uncertainties on projected discovery limits with an emphasis on low WIMP masses (less than 10 GeV) when solar neutrino backgrounds are most important. We find that accounting for astrophysical uncertainties changes the shape of the neutrino floor as a function of WIMP mass but also causes it to appear at cross sections up to an order of magnitude larger, extremely close to existing experimental limits, indicating that neutrino backgrounds will become an issue sooner than previously thought. We also explore how neutrinos hinder the estimation of WIMP parameters and how astrophysical uncertainties impact the discrimination of WIMPs and neutrinos with the use of their respective time dependencies.


Power grid design and maintenance are conducted to solve the problems caused by load growth over time and to stay within the constraints of voltage drop, power factor, etc. Typically, solutions to these problems are optimised individually. Considering multiple problems simultaneously and applying different solutions require vast design space exploration. This exclusively needs advanced algorithms and complex global optimisation methods which are not easily-applicable in different scenarios. In the state-of-the-art methods, for solving multiple problems simultaneously, these individually optimised solutions are applied sequentially to the power grid. In this so-called uncoordinated method, the final solution may not be optimal solution considering all the variables, since it is considering the overlapping effect of the solutions on the power grid. To validate the compartmentalisation method, a detailed distribution grid has been modeled. After analysing the possible solutions and optimisation, power loss was reduced 45% and total cost decreased by 71%, compared to the uncoordinated method.


The Salerno "School" of Medicine was the most representative institution in medieval Salerno and for a long time historians have been involved in the complex task of reconstructing its origins and development. As far as its origins are concerned, research is objectively limited due to a lack of sources until the 11th century, while more information is available at a later date. However, medicine in Salerno appears to have been characterized since its origins by a strong multiculturalism, as a synthesis and expression of multiple cultural components. In this paper we propose a reconstruction of the "School"'s history and show how it is a reflection of the very history of the city. Therefore it is no coincidence that the heyday of the "School" corresponds to the period when Salerno reached the acme of its political prestige and economic development. The article then focuses on the history of the Jewish community, which reflects as well the general history of the city, and also that of the whole of Southern Italy in the late Middle Ages, much more than has previously been brought to light in historical studies. Moreover, the size and the wealth of the Jewish community – not unlike that of other similar communities in the South – was affected by the progressive crisis of Salerno especially in the 14th and 15th centuries, when the Jews gradually tended to move to places that could offer them greater possibilities. An interesting point of interconnection between the history of the "School" and that of the Jews of Salerno is the Cronica Elini, a text that narrates the legendary origins of the city and its "School", in which the Jewish component plays an important role. In the final part of the paper we propose an interpretation of the work, arguing for a relatively late date of composition, as the result of an attempt to enhance the prestigious history of medicine in Salerno and its multiculturalism, when the "School" – and all at once, the Jewish community – had consumed their crisis.


The normal procedure in acoustical designs usually emphasizes audience acceptance. This approach often results in unfavorable acoustical conditions for performing artists, both instrumental and vocal. The imbalance occurs form neglect of the musicians' need for mutual communication, and too great an emphasis on achieving ''optimum'' reverberation conditions. There have been notable examples of halls meeting accepted reverberation criteria which have nevertheless proved to be unsatisfactory, and many of these gave trouble because of performance difficulties as transmitted to the audience. Conversely, reverberation conditions can differ considerably from the norm, and still provide a satisfactory hall if the stage is properly designed. Study of a variety of halls strongly suggest that an essential requirement for music is that conditions should be suitable for performers. Architectural designs that provide ample sound reflecting and diffusing structures on stage to enable artists to hear each other well, bl...


Potato yield and quality are highly dependent on an adequate supply of water. Thermal Infrared (TIR) imagery data can be used for calculating the Crop Water Stress Index (CWSI), which may be used as a means for managing the dynamic demands of water in potato fields during the growth season. Field experiments were conducted in 2010, 2011 and 2012 in commercial potato fields (Solanum tuberosum L. cv. Desiree; drip irrigation) at Kibbutz Ruhama, Israel (31.38° N, 34.59° E). Two scenarios of water deficit were tested, a short term water deficit, induced by suppressing irrigation for a number of days before field campaign, and a long term cumulative water deficit induced by reduced seasonal application. TIR and RGB images were used for delineation of canopy temperature and calculation of CWSI throughout the season. Plant water status was evaluated by measuring leaf stomatal conductance (SC). Data from 2011 showed that there is a statistically significant effect (α = 0.05) of the cumulative irrigation treatments on tuber yield, and that tuber yield is highly correlated with CWSI ((0.62≤R2≤0.93). These findings may imply the potential of using CWSI values as a threshold for managing irrigation, and will be further examined with data from the 2012 spring season.


ID: 27 for Scars 2020 (Auto-Generated February 26, 2020 8:38 pm) Copyright 2020 Scars 2020 powered by WPAbstracts Pro Autologous Fat Transplantation for Depressed Linear Scleroderma en Coup de Sabre – Induced Facial Atrophic Scars on the Forehead: Improvement of Appearance and Control of Disease Activity? by JÜRGEN BAUERSCHMITZ | Hautklinik Universitätsklinikum Erlangen Abstract Id: 27 Submitted: December 1, 2019 Event: SCARS 2020 Topic: Dermatological ScarsId: 27 Submitted: December 1, 2019 Event: SCARS 2020 Topic: Dermatological Scars Introduction: Facial linear scleroderma results in depressed atrophic scars. Structural fatgrafting is suitable for the volumetric restoration. Methods: A 48-year-old female patient with linear scleroderma was treated for 25 years with Penicillin , Methotrexate , Mycophenolatmofetil, UV-A1, Tacrolimus. This decreased inflammation, but progression of depressed scars was not stopped. Two linear depressed atrophic scars were noted on the left mid-forehead with involvement of the glabellar nose and supraorbital eyebrow region, a third mould-like was nasolabial . Autologous fat transfer was performed according to the german guideline : Lipoaspiration under Tumescent-LokalAnaesthesia with a vacuum-syringe. After gentle filtration the lipoaspirate was injected. After two years a second grafting was conducted. Results: The disease-progression with deep grooves could be stopped. After a good primary success fronto-nasal and fronto-orbital and a moderate success nasolabial the depressions subsequent relapsed partially within one year. A second lipotransfer was conducted. Discussion: There is increasing experience in autologous fat-grafting to improve contour defects in the face associated with local scleroderma leading to depressed atrophic scars like "en coup de sabre".Our patient showed volumetric improvement on the medial forehead with the glabellar nose area and the lateral forehead with the supraorbital eyebrow area for one year but poor correction nasolabial. Therfore a second grafting was performed. In addition to the augmentation we observed a possible reduction of disease activity concerning the scar-development, which had progressed further despite multimodal immunomodulating therapy.

An effect in concern of limiting the progression of the disease and reversing the fibrosis und atrophy would be a favourable outlook. Autologous fat-grafting provides a rich source of cells: adipocytes, stem cells, endothelial cells and vascular smooth muscle cells potentially contribute to the effectiveness of this treatment. Studies are necessary to define the indications and points in time of fat-transplantation in linear scleroderma.


Eight insecticides were evaluated for control of grape phylloxera at Wooster, Ohio. Plots consisted of 3 Clinton vines with eight feet spacing in rows and nine feet separating rows, with 4 replications in randomized blocks. Insecticides were sprayed on the foliage at the rate of 2 gal per treatment (90 gal per acre) using a Hudson 6209, 2 gal. Favorite sprayer at 40 psi with the exception of Temik which was applied to soil in granular form. Temik granules were applied 1.5 feet on each side of the vineyard row. The granules were distributed uniformly in the bottom of a 1.5 inch furrow along the sides of each replicate and covered with soil as soon as applied. Soil was moist at time of application. All insecticides were applied on June 18, 1975 when grapes were the size of BB's. A second application was made with all compounds except PP 557 and Temik on June 30, 1975 when berries were ca. 9 mm in diameter. In sampling, 10 shoots were chosen at random from the center of each plot, half from each side of the row. The number of galls was recorded on the 10 apical leaves of each of these shoots. Two fungicide applications were made to entire experimental area: (1) May 22, 1975; 8 oz of Captan 50W plus 4 oz Benlate 50WP per 50 gal water: and (2) June 23, 1975; 1.5 lb Captan 50W plus 8 oz Benlate 50WP per 50 gal water.


This paper explores two related questions: 1) Does the institutional design of the governance arrangements of a city make a difference to the performance of place-based leadership? And 2) Does the leadership style of the individual exercising mayoral leadership in a given city make a difference to the way the city is governed? The paper, which is based on a five-year longitudinal study of place-based leadership in Bristol (known as the Bristol Civic Leadership Project), draws on surveys of citizens and civic leaders, on interviews and on participant observation. An introduction outlines the two central questions addressed by the paper. The next section explains the mayoral model of place-based leadership. It outlines the pros and cons of this model of urban governance and then describes how, in a referendum held in May 2012, the citizens of Bristol decided to introduce a directly elected mayor model of governance into their city. This is followed by a section providing data on citizen and civic leader 'before' and 'after' perceptions of the strengths and weaknesses of the directly elected mayor model. The results are striking and reveal important differences between different socio-economic groups in the city and between realms of leadership within the city. The following section turns to consider styles of mayoral leadership. The first two directly elected mayors in the history of Bristol - Mayor George Ferguson (2012-2016) and Mayor Marvin Rees (elected in May 2016) – have very different styles of leadership and these are compared. A final section discusses important themes relating to place-based leadership that flow from the analysis.


In light of recent debates regarding the scope and basis of inherent executive power, particularly with regard to foreign affairs and national security, this Essay examines different conceptions of executive power in five modern democracies. The Essay's study of British and German parliamentary systems, the semi-presidential French system, and the presidential Mexican and South Korean systems suggests that executive power is highly contingent and shaped by political context. The Essay identifies the common features of all these governmental structures, including the fluid line between executive and legislative power, and emphasizes that all of these nations have recognized the importance of placing limits on executive power, including in the spheres of foreign affairs and national security. These comparative examples thus provide a counterweight to recent arguments that executive power inherently requires unchecked authority in these spheres.


A one-dimensional mathematical model was developed to simulate pH control using an encapsulated phosphate buffer during denitrification in a sand column. The parameters required for the model were obtained from direct physical measurement, from a tracer study to characterize the dispersion coefficient in the column, and from batch experiments designed to obtain an empirical expression describing the variation of the first-order rate constant for the encapsulated buffer core release with pH. First-order kinetic constants describing the rates of denitrification and ethanol biodegradation were obtained by fitting the model to column runs without the encapsulated buffer. With these parameters, the model was subsequently used to predict the performance of column runs containing the encapsulated buffer. Since denitrification was essentially complete in the sand columns, an increase in the effluent pH was observed. This pH increase was counteracted by the controlled release of the acidic core of the encapsulated buffers added in the columns. The model reasonably predicted the release of the encapsulated buffer core and the performance of the encapsulated buffer for controlling pH in the column.


This article comments on the draft research guidelines prepared by Smith-Sebasto arising from the 1997 Annual Conference of the North American Association for Environmental Education (NAAEE). It critically reviews premises regarding: (a) the viability of one set of guidelines for all qualitative research approaches; (b) the viability of one set of guidelines for designing, conducting and reporting research; and (c) the uniqueness of EE research. It also reviews the workshop setting as a venue for addressing research training needs and for developing research guidelines. Then, it reviews the draft guidelines for organization,scope, inclusiveness, bias, and attention to evolving practice. It closes with a recommendation that these guidelines be more carefully reviewed and refined.

This course will focus on four aspects of international criminal law. First, we will begin the semester with a general introduction to the historical evolution of international criminal law over time. This will include a discussion of the development of the four primary crimes of "international concern" – war crimes, crimes of aggression, crimes against humanity, and genocide. This discussion will also include a description of the international tribunals established to prosecute these crimes of international concern, including the Nuremberg Tribunal and the International Criminal Court in The Hague. This introductory portion of the course will also focus on fundamental issues related to international criminal law, such as sources of international law, what crimes are international, and how is jurisdiction established over international crimes.

 Dr Frankenburg has raised a number of interesting points. Initially, he addresses concern about the use of "questionable" scores for individual sectors of the Denver Developmental Screening Test (DDST). Although we understand that the DDST should not be scored by individual sectors, to obtain a total test result each sector must be scored. On page 26 in the DDST manual/workbook currently distributed, a questionable score results with the following circumstances: "1 or more sectors with 1 delay and in that same sector no passes intersect the age line" (underline appears in manual).1


Immature gametocytes of Plasmodium falciparum ( P. falciparum ) are localized in the bone marrow and spleen for their development. Upon maturation, these immature gametocytes release to the peripheral circulation for sporogony and subsequent reproductive phases which leads to malaria transmission. Garnham (G) bodies are curious structures seen rarely inside immature gametocytes and never reported in malarial literature after their first identification by Garnham in 1933 from Kenya in a fatal malaria case. Here, a case of fatal malaria from India is reported for the first time, with the demonstration of peripheral microscopic localization of P. falciparum G body present inside an immature gametocyte. A 23-year-old male patient died of cerebral malaria and multi-organ dysfunction within 19 h of hospitalization to a tertiary care hospital. Examination of his peripheral blood on admission using Giemsa-stained light microscopy followed by differential interference contrast imaging in a confocal microscope revealed presence of a G body inside an immature, stage-III gametocyte of P. falciparum . The patient was diagnosed to have cerebral malaria along with jaundice and acute renal failure, and had received antimalarial artesunate along with other therapies and intensive care. Microscopic localization of P. falciparum G body inside immature gametocyte (stage-III) especially in peripheral human circulation, is an extremely rare observation in clinical malaria, only second to Garnham's discovery since 1933. It portrays a peculiar phenomenon in the malaria parasite's life cycle that may derive newer avenues for exploring the genetics underlying the "trade-offs" of immature and mature gametocytes, prospects for transmission-blocking drug discovery and vaccine design strategies.

At Copenhagen International School of Performing Arts, English is the Lingua Franca (ELF) of artistic exploration. With a non-conformist approach to the use of ELF, highlighting a body-mind insight into the language over correctness, a latent, expressive potential of ELF is explored through a psycho-physical training. The predominant technique is Movement Psychology (Laban/Malmgren), which examines the interdependence between, on the one hand, text, language, and narrative and, on the other, the embodiment of the Jungian unconscious. The paper analyses the process and the methods of staging the production entitled Re: ORESTES , based on Mee's play Orestes 2.0 , applying the described methodological exploration. The play was rewritten and remoulded by the performers throughout a rehearsal process, which focused on interlacing the performers' highly diverse cultural horizons (Gadamer) in a common mega-text, in an attempt to fuse the familiar with the alien, the personal with the collective, and to channel, shape and articulate the material within ELF. The paper details two different examples of this transformative remoulding process. One actor wrote a completely new text, which was performed in the heightened style of "the Queen's English". Another actor performed a part in a poly-glottal combination of Ancient and Modern Greek (her mother tongue) and ELF. In this process, both performers sought to transcend the preconceived limitations of their individual cultural horizons as well as of the English language.

A s our species evolved over the millennia, given the intense pressures for survival, we humans have focused on pathology. What is "wrong," "threatening," "problematic?" We attend to threat and consequent fear before heeding other concerns. It is no surprise then that social psychology with its domain of interpersonal interactions has heavily researched the "undesirable" and "negative" social behaviors of obedience (Milgram, 1963) and bullying and intimidation (Zimbardo, 2007). How refreshing it is then to have a spotlight turned onto a human interaction that is optimistic, altruistic, and socially productive. Surprisingly, there is little research on the nature of heroic action, nor money spent on investigating how to get people to follow their conscience, their moral compass. After decades of researching the "evil" behavior in prison life, the senior author of this video, Phil Zimbardo, a social psychology researcher, has turned his attentions toward more positive human interactions. And the junior author, Bill Roller, an accomplished group co-therapist (Roller & Nelson, 1991), was inspired by his previous in-depth DVD interview with Daniel Ellsberg and Phil Zimbardo (Brabender, 2014) to bring the knowledge and skills of group therapy to demonstrating the social underpinnings of heroic behavior. The authors' joint efforts bear fruit in this productive collaboration, with each providing separate yet overlapping knowledge of human interaction research (social psychology) International Journal of Group Psychotherapy, 68: 124–131, 2018 Copyright © The American Group Psychotherapy Association, Inc.

While companies engaged in building and repairing pipelines in rural environments seldom have to deal with enraged commuters and irate business owners like gas utilities that must maintain service in congested urban areas, the challenges of planning and carrying out long-distance projects are formidable. The main challenge is the very complexity of such projects and the fact that they must comply with an extensive list of federal and state regulations. This paper discusses several strategies that gas utilities have used on pipeline projects: partnering between the utility and its contractors, major repairs after ``100-year storms`` in California, research on public attitudes towards gas pipelines, and routing through wetlands.


The use of statistical modeling for the development of information and mathematical culture of schoolchildren is considered in the article. A comparative analysis of various statistical modeling tools: spreadsheets, programming languages, interactive mathematical environments is carried out. Examples of the simplest statistical models and their implementation using these tools are given: experiments with coins and cubes, random selection without returning, Bernoulli tests before the first success. The most interesting theoretical issues that arise during statistical experiments and are available for study in the school mathematics course are highlighted. Several games with probabilistic content are considered, demonstrating well-known statistical paradoxes. It is shown how the skills accumulated in the process of statistical modeling can be used to study real situations and perform independent research and design work on this basis.


Maintaining hardware cache coherence on future CMPs becomes increasingly important and difficult as the number of cores keeps accelerating in mainstream multicore chips. The simple snooping-bus coherence scheme is not suitable due to its limited scalability. The sparse coherence directory approach may incur extra cache invalidations due to a topological mismatch between the coherence directory and the directories of all cache modules. In this paper, we propose an innovative CMP coherence directory that has three important properties. First, the directory has a simple set-associative design with small associativity. The number of directory entries matches the total number of cache blocks. Second, an augmented Directory Lookaside Table (DLT) allows blocks to be displaced from their primary sets in the coherence directory for alleviating hot-set conflicts. Third, to avoid expensive presence bits, each copy of a block along with the located core ID occupies a separate directory entry. Performance evaluations based on multithreaded and multi-programmed workloads demonstrate significant advantages of the proposed CMP directory over directories with traditional set-associative or skewed associative designs.

Pain is characterized as a multidimensional expression,
involving quantitative, sensitive and emotional aspects.
Orofacial pain is classified in those kinds of pain resulting
from Temporomandibular Disorders (TMD), frequently
related to chronic sintomatology. Such conditions
are associated to various pathophysiological, psychological,
social and cultural aspects. The objective of
this literature review is to refer the main psychological
factors that affect patients with chronic TMD, emphasizing
the importance of the identification of emotional
factors. The diagnosis depends on a careful clinic examination,
aiming at an early diagnosis and the identification
of the patient's psychological factors with chronic
TMD which are contributing to the onset or perpetuation
of the disorder by increasing muscle activity, the
presence of cognitive and behavioral factors. The most
frequent psychological aspects in these individuals are
depression and anxiety that is why they need interdisciplinary
intervention because of their physical and psychological
nature and need psychology for optimizing
the dental treatment.


Acid-phase reactors in anaerobic digestion are widely used for treating solid waste such as kitchen waste and sludge. The purpose of this study was to find the optimum control parameters for corrosion behavior in-vessel .Various physical and chemical parameters were monitored to evaluate water soluble imidazoline inhibitor effect on the microbial communities in acid fermentation of sludge and corrosion inhibitors for steel alloy. The metal products pieces were tested by surface-active agents with corrosion inhibitors in low molecular weight organic acids, mixing with NH4Cl-NH4HSH2O to simulate the sludge and acid waste. Results show that water soluble imidazoline materials are a kind of excellent performance corrosion inhibitor, which can meet the requirements of environmental protection and has no adverse effect on metal containers and fermentation process. Inhibition of corrosion by adding an imidazoline ranging in 10–20 mg/L at temperature below 100°C is limited. The influence of temperature on inhibition is small.


This investigation deals with the equilibration of heat conduction simulation in a very thin film using molecular dynamics. Two parameters, the positional order parameter and the kinetic H‐function, are employed simultaneously to monitor the evolution to the equilibrium. With the different boundary conditions, material parameters, and molecular lattice configurations, the results of the simulation show that the combination of the two parameters can give a consistent prediction to the approach of the equilibrium. At the equilibrium state, the process of heat conduction in a thin film is studied to understand the macroscopic behaviour from the standpoint of molecular dynamic motions. The method used can be applied to solve other microscopic flow and heat transfer problems using molecular dynamic simulation.


Dc magnetization,ac susceptibility,magnetic relaxation and the aging effect of doped cobaltite Nd1-xSrxCo O3( 0. 10≤x≤0. 20) have been studied systematically. The samples were synthesized by conventional solid state reaction method. The dc magnetization,ac susceptibility,magnetic relaxation and aging effect of doped cobaltite Nd1-xSrxCo O3 were measured by using the physical properties measurement system of Quantum Design. The perfectly mirror symmetry of the aging effect curves shows the presence of frustrated phenomenon in materials. The magnetic relaxation fitted results show that this interaction in ferromagnetism magnetic clusters causes to spin glass state in Nd1-x SrxCo O3. Therefore,the aging effect and memory is the intrinsic magnetic properties of doped cobaltite indeed.

Since the 1990s, many dancers from Cuba have found work in North American and Western European ballet ensembles. This chapter describes how their international dance careers reflect high-skilled labor migration in the global economy, as well as the decentralizing expansion of ballet's labor market. Migrant Cuban dancers cite a depressed local economy and the artistic stagnation of the Ballet Nacional de Cuba as fundamental reasons for looking for work in international ensembles. Their exodus is also political—extending into the present practices and discourses associated with the Cold War concept of defection. The numerous departures constitute a detrimental form of brain drain for Cuban ballet, which loses precious human capital and is relegated to the subaltern role of labor supplier for the international ballet community. Yet, this diaspora could also fuel brain gain—a scenario in which émigrés such as Carlos Acosta return home to reinvest in local institutions the knowledge and resources acquired abroad.

The utility model discloses a magnetic-attraction type water pump, which comprises a casing, a motor component and a pump cover assembly. The motor component comprises a rotating shaft, a rotor tightly sheathed on the rotating shaft and a stator tightly sheathed on the rotor. The two ends of the rotating shaft are fixed inside the casing through a bearing assembly. The pump cover assembly comprises a pump cover chassis, an impeller and a pump cover with a water inlet and a water outlet. A first permanent magnet consisting of at least one N pole and at least one S pole is tightly sheathed at the top end of the rotating shaft, a second permanent magnet attracting with the first permanent magnet is arranged on the impeller, the number of poles of the second permanent magnet is the same as the number of poles of the first permanent magnet, and the corresponding poles of the two permanent magnets are opposite. An inverted L-shaped seal ring is arranged on the upper ring of the casing mounting surface at the upper part of the casing in a surrounding manner, and a screw cover presses the lower part of the seal ring. The impeller and the motor component of the water pump are separately mounted, instead of direct mounting, the impeller is tightly sucked on the pump cover chassis by virtue of the strong magnetic attraction force of the permanent magnets, and the motor component rotates to drive the impeller to rotate, so as to generate water flow.


The present report presents results obtained from an interlaboratory test. 28 participants, mainly from industry and research institutes, measured glass transition temperatures (Tg) by differential scanning calorimetry (DSC) on four different polymers. The materials used were poly(methyl methacrylate) (PMMA), polycarbonate (PC), polysulfone (PSU) and amorphous polyamide (PA 6I/6T). The measured data were collected by EMPA and were evaluated using a robust statistical method. Repeatability and reproducibility data were of special interest. The repeatability limit (r) of glass transition temperatures measured according to DIN 53765 was found in the region of 1–2°C, and the reproducibility limit (R) was around 3–4°C. In addition to the DIN standard, the set of interlaboratory test data was evaluated and considered according to some different approaches and was correlated with data from other EMPA interlaboratory tests performed previously. It was shown that the investigated statistical parameter was always in a similar dimension. The data of the PA sample were found to be an exception. Due to the hygroscopic character of polyamide, the r and R values increase sharply, to an almost three times higher reproducibility limit. Overall, the evaluated data can be used to estimate the results of own and external Tg measurements and their compatibility. The report should therefore support daily work in analytical laboratories where glass transition temperatures are measured by DSC.


In this work, we numerically and experimentally investigate topological rainbow trapping and energy amplification of acoustic waves in a gradient phononic crystal (PC) structure. Thanks to the acoustic valley Hall effect, topological interface states (TISs) are generated along the interface between two PCs with different topological phases. To achieve rainbow trapping, we introduce the gradient into a 3D-printed PC structure by varying the geometrical parameter of scatterers along the interface. The incident acoustic waves at different frequencies split, stop, and, hence, are significantly amplified at different positions. Notably, the rainbow trapping of TISs is immune to random structural disorders. The topological rainbow trapping is promising for the design of broadband energy harvesters with excellent robustness.


This paper describes a new methodology for the extraction of an extrinsic parasitic network suitable for scalable electron device models. The extraction procedure is based on the data obtained through Full-Wave Electro-Magnetic (FW-EM) analyses of the passive structure of a reference device. The new topology proposed proves to be scalable according to simple linear rules derived from geometric considerations. This new parasitic network is used together with a scalable intrinsic device model in order to predict the behavior of different 0.25 μm GaAs PHEMTs (total gate-widths between 300 and 900 μm) belonging to a standard process for millimeter-wave applications. Better accuracy with respect to conventional modeling approaches, is proved up to 80 GHz.


Reverse-impact method used to measure the high-pressure sound velocity in shock-compressed metals was described.Two reverse-impact set-ups,Ta/LY12 Al buffer/LiF window and Ta/LiF window,were used to measure the sound velocity in shock-compressed Ta over the range of 110~131 GPa.Measured longitudinal sound velocities in Ta are consistent with the data reported by Brown J M,et al.No significant effects of LY12 Al buffer on the measurement uncertainty of sound velocity were found because of little difference in impedance between LY12 Al and LiF.The longitudinal sound velocities of LY12 Al buffer were determined at 110 GPa and 131 GPa.The data combining with those reported by McQueen R G show that the longitudinal sound velocities in LY12 Al decrease gradually to bulk sound velocities with pressure over the range of 125~150 GPa.


In the US context Fluxus is understood as an advance of the '60s radicalism. The assumption that Fluxus was opposed to consumption culture, as that embodied by Pop art, is among the interpretations that renew such a view. Examining the example of Implosions Inc., a short-lived but nevertheless interesting commercial enterprise formed by Robert Watts, Herman Fine and George Maciunas in 1967, this essay focuses its attention on the complex relationship between Fluxus and commercial culture. Implosions Inc. was a project in which many Pop artists were asked to participate along with its Fluxus founders, and it was intended as another step forward in the transformation of the artist into a commodity mass-producer. In analyzing this phenomenon, this article questions assumed principles in the Neo-avantgarde theory like the distinction between art production and culture consumption. The essay, however, will try to establish another paradigm that draws the differences between Pop art and Fluxus as the kind of audiences both these tendencies tried to conform. As a conclusion, the article fleshes out some ideas on individualism that were developed by Maciunas, which shed light on the notions surrounding the idea of collectivism as developed in Fluxus.
