The application of thermal differential dieless forging technology in shaping shaft-disc type components was presented.And the effect of four parameters,initial forging temperature,friction coefficient,heating zone length and thermal strain,on the final deformation results of blank was analyzed.The analysis results indicate that increasing initial forging temperature and friction coefficient is helpful for getting a larger local deformation of blank but the heating zone length and thermal strain have no obvious effect on the final deformation results.


The objective of this project is to retrofit the previously developed High Efficiency Advanced Coal Combustor (HEACC) to a standard gas/oil designed industrial boiler to assess the technical and economic viability of displacing premium fuels with microfine coal. This report documents the technical aspects of this project during the fourteenth quarter (January `95 through March `95) of the program. The ABB project team met with cognizant DOE-PETC and Penn State personnel on February 15, 1995 at Penn State to discuss our ideas for a new burner (RSFC-based) to replace the HEACC burner prior to the long term ({approximately}1000 hrs) demonstration phase of this project. The main reasons for the proposed new burner were to improve combustion efficiencies and NO{sub x} reduction. Recent, experience at MIT with 5 million Btu/hr coal firing experiments on RSFC burner have shown remarkable performance. Results indicate that RSFC-based burner has the potential to produce lower NO{sub x} and higher carbon conversion efficiencies than the HEACC burner. M.I.T. developed the RSFC burner and obtained a patent for the concept. A decision was made to go with the new, RSFC-based burner during 1000 hr demonstration. ABB-CE will fund the costs ({approximately}$50K) for design/fabrication of the proposed new burner. Penn State plans to improve coal handling by installation of a gravimetric feeder and redesign/installation of a mass flow bottom on the surge bin.


The doctorate in science presupposes the highest level of academic training and guarantees first level human resources, hence the need to systematically monitor them. The objective of the study was to develop an index to measure doctoral self-development in academic areas, as a basis for evaluating the results of its corresponding training management. For its elaboration a mixed methodology was conceived that integrated qualitative and quantitative methods. As a result, it obtained the doctoral self-development index (DSI), which makes it possible to measure the main results of the management of the training of doctors in science in academic areas. It was concluded that the use of the proposed index provides universities with a novel tool to systematically monitor doctoral training in their areas.


The primary objective of this volume is to explore the possible interrelationships of biochemistry and function (or "cerebral excitability") within the nervous system. A considerable portion of this effort is devoted to the chemistry and physiological properties of membranes and their presumed relationship to the problem of ion transport and excitability. Among the topics discussed are the relationship of metabolism to excitation; the role of lipids, phosphoproteins, and enzymes in the maintenance of electrolyte balance and transport; and certain morphological characteristics relating to membrane structure and metabolism. Some effort is devoted to reviewing a few selected theories regarding the problems of ion transport in excitable tissues. Unfortunately much of the discussion of such theories as well as the material as a whole suffer from the bias of the author's views on the subject. This volume is of value in that it exemplifies the kind of thinking and methodology involved in


This paper briefly presents non-linear finite element models based on layered Mindlin plate element formulations. An eight-noded isoparametric plate element is used. The Mindlin thick plate theory is applied to account for transverse shear deformations. The layered technique is adopted in order to allow for the development of cracks through the thickness. Each layer is assumed to be in a state of plane stress. The reinforcing steel is treated as an equivalent layered material having uniaxial stiffness and is idealised using a bilinear stress-strain curve. The non-linear effects due to the cracking and crushing of concrete and the yielding of steel reinforcement are included, An incremental finite element computer program is developed which simulates the load-deflection behaviour of reinforced concrete structural slab systems. Some numerical examples are considered to study the effectiveness of the proposed model.


Nowadays, computer simulations and experiments are closely interlocked. However, the data and analysis workflows are often barred into "silos" of knowledge — even for routine simulations. Here, we show how a typical electronic laboratory notebook (ELN) environment can be seamlessly integrated with a computational modelling infrastructure. We developed a protocol to initiate advanced molecular or atomic simulations directly from an ELN. Such integration ensures that all the relevant sample and experimental data are transferred from the ELN to the modelling infrastructure, and — once the calculations have completed — back to the ELN. The presented protocol works similar to sending out a sample for external characterisation and enables experimentalists to routinely perform "routine" simulations to compare with their experiments while keeping track of the full experiment and simulation provenance. We illustrate our protocol with some examples of geometry optimisation followed by the calculation of adsorption isotherms, but the implementation can be readily generalised to other techniques such as optical absorption or X-ray photoelectron spectroscopy.


ABSTRACT This essay challenges conventional understandings of how research methods courses are taught in the social sciences and the humanities. Currently, students in American Universities are trained in techniques on how to conduct and disseminate research. While these skills are essential, we argue that, as educators, we need to teach students to recognize that the research process does not simply entail method, logic and reason. It begins with the self and with the assumption that emotions have a place in higher education. By using what we call Compassionate Research as a model, we contend that our humanity becomes the point of entry into the world of research. This pedagogical model relies on three interconnected principles, namely the abilities to question, self-question, and empathize. Its implementation in the classroom helps to foster culturally sensitive research and to promote self-awareness that translates into meaningful interactions with our communities.


Purpose: Coronary angiography can cause post-procedural pain, and limited flexibility in the hips and knees may contribute to this discomfort. This study was designed to assess the flexibility of the hip and knee and its relationship with pain after femoral angiography. Methods: This cross-sectional study was conducted on 42 participants (27 men and 15 women, aged 30-85 years) after non-emergency angiography at Dr. Shariati Hospital. Demographic data, employment status, and angiography history were collected through an individual data questionnaire. Muscle flexibility was assessed using a goniometer and tape measure, and visual analog scale (VAS) was applied to evaluate the score of pain. A Spearman correlation coefficient and Kruskal-Wallis tests were used to examine the relationship between variables and pain. Results: The analysis revealed no significant difference in mean pain scores between men and women (P=0.662), employment status (P=0.265), or history of angiography (P=0.262). We observed positive correlations between pain and the modified Thomas test for hip extension, active knee extension test, and forward bending test (rho=0.745, rho=0.594, and rho=0.433; P=0.00, P=0.00, and P=0.04, respectively). Conversely, the modified Thomas test for knee flexion showed a negative correlation with pain (rho=-0.591, P=0.00). No significant differences were found between the sit-and-reach test and pain (rho=0.337, P=0.29). Age demonstrated a positive correlation with pain (rho=0.312, P=0.04). However, weight did not show a significant correlation with pain (rho=-0.074, P=0.64). Conclusion: A relationship was observed between some flexibility tests and pain. Reduced hip and knee flexibility correlated with higher pain levels after femoral angiography. While age showed a positive relationship with pain, weight did not show any relationship with pain. These results emphasize the importance of considering flexibility in managing pain after femoral angiography.


In order to keep the pollution levels below permissible limits and also to forecast the final concentrations to be reached, current patterns and dispersion characteristics are required for water quality problems in lakes and coastal regions. In this case, it is necessary to solve the dispersion equations that include transport, diffusion and reaction processes to find the distribution and concentrations of pollutant. In this study, a numerical model was developed for simulating pollutant dispersion in well-mixed lakes and reservoirs. The model is based on solving dispersion equation using the Kewton-Raphson algorithm and results of hydrodynamic model. The developed model can be used for long-term distribution of conservative or non-conservative pollutants in lakes and reservoirs.


A laboratory study was performed on how young Atlantic cod (Gadus morhua) regulate their swimming speed according to available food. A circular tank 15 m in diameter was divided into six sectors, each containing two cod ranging in length from 29 to 42 cm. Live fish 5 cm long on average were used as prey. For the first 48 d food intake was changed every 1 or 2 wk equally for all six groups. During the last 31 d each group received different amounts of food. The mean swimming speed was highest (0.6 bl/s) when food intake was about half the maximum intake and lowest (0.2 bl/s) when food was unlimited or not available. Swimming metabolism was related to food intake in a similar way, but with a larger difference between the most active (50 mg O2∙kg−1∙h−1) and the least active group (10 mg O2∙kg−1∙h−1). Maximum sustained swimming metabolism was estimated to be about 0.6 times the standard metabolism. The estimated energetic cost of swimming as a percentage of energy obtained from the food decreased with food in...


This paper presents the design, fabrication, and characterization of a MEMS actuator with large static deflection as a waveguide-mounted variable millimeter-wave phase shifter. The actuator is composed of a pair of interdigitated microplates actuated by vertical comb-drives and suspended by SU-8 torsional springs. The SU-8 spring possesses a thin metallization top layer and a reverse-T-shaped cross-section enabling low torsional stiffness and high in-plane stability. A maximum mechanical deflection of 10.3° is obtained under a dc actuation voltage of 35 V. The dynamic characterization of the device shows that the resonance frequency of the torsional mode is well separated from the other three bending modes, confirming the designed low torsional stiffness and high in-plane stability. The torsional viscoelastic creeping is measured as a function of time at different loads and shows a maximum of 0.5° for an applied voltage of 27.5 V. A high operation cycle test is conducted and the metalized SU-8 spring withstands 800 million cycles without showing fatigue. RF measurements show that a variable mechanical deflection angle between 0° and 8.2° results in a variable transmission phase shift up to 58.0°. The measured insertion loss is always below 5.1 dB at 98 GHz, corresponding to a figure of merit of 11.5°/dB.


The FDA rejected drug-maker Pharmacia's bid to relax the gastrointestinal (GI) safety warnings on its label for the Cox-2 inhibitor celecoxib (Celebrex). This setback was made only slightly better by changes to the label's section on cardiovascular effects. In reacting to the news, Pharmacia presented a unified front of reassuring public relations professionals. But the bottom line is that the FDA said Celebrex is no safer than the much less-expensive generic nonsteroidal anti-inflammatory drugs (NSAIDs). "FDA agreed with its Advisory Committee recommendations of February 7, 2001 that CLASS [Celecoxib Long-term Arthritis Safety Study] did not show a safety advantage in upper gastrointestinal events for Celebrex compared to either ibuprofen or diclofenac," according to the FDA. (See FDA, 2002.) Reaction to the FDA's rejection of Pharmacia's bid was swift and merciless. "With the FDA action, there appears to be no good reason to prescribe Celebrex, given that it's many times more expensive than ibuprofen," Sharon Levine, executive vice president of Kaiser Permanente, told the Wall Street Journal. (See Harris, 2002.) The drug labeling for Celebrex will continue to carry the standard GI warnings about the not-insubstantial risks associated with all NSAIDs. As with the label carried by its competitor, rofecoxib (Vioxx, Merck), the Celebrex label contains several paragraphs warning against the possibilities of GI ulceration, bleeding, and perforation—all potentially occurring without warning. It also includes a precaution about couse of Celebrex with warfarin. "Bleeding events have been reported, predominantly in the elderly, in association with increases in prothrombin time in patients receiving Celebrex concurrently with warfarin," the label notes. The new Celebrex label includes a table that compares rates of complicated and symptomatic ulcers among Celebrex users according to age (patients over or under age 65) and aspirin use (those taking Celebrex alone or Celebrex with aspirin). The results show a sixfold difference between those in the lowest-risk group (0.47% in those under age 65 taking Celebrex alone) and those in the highest-risk group (3.06% for those over age 65 taking Celebrex with aspirin). The better news for Pharmacia was that the FDA will permit the addition of relatively favorable safety data from CLASS, suggesting that rates of hypertension, edema, and serious adverse cardiovascular events were no higher among patients taking Celebrex (at twice the highest approved dose) than in those taking ibuprofen and diclofenac. This is attributed to the fact that patients in the CLASS study were permitted to take aspirin—unlike those in the comparably large Vioxx trial known as VIGOR. Most observers agree that aspirin protects users of Cox-2 drugs from cardiovascular events, while largely negating the drugs' potential GI benefits. The Celebrex label notes that the drug "should be used with caution in patients with fluid retention, hypertension, or heart failure." By contrast, the new label for competitor Vioxx includes a separate section of vigorous warnings, including a note that the risk of developing a serious cardiovascular event was significantly higher in patients treated with Vioxx (n = 45) than in patients treated with naproxen (n = 19). All of which leaves physicians in the unenviable position of trying to determine whether either drug is safer in elderly patients who are simultaneously at risk for both ulcers and cardiovascular events. The current data appear to say they are not.


PurposeWith self-employment providing earning opportunities to many working poor in developing countries, the study examines its role in alleviating poverty.Design/methodology/approachA five-year average of 56 developing countries from 1995–2019 is used. The empirical analysis is based on the dynamic two-step system GMM approach. While poverty is measured in terms of incidence, depth and severity; self-employment is used in three forms – total, male and female.FindingsIn line with the theoretical prediction, evidence suggests that self-employment in developing countries reduces poverty, albeit smaller magnitude. However, the poverty-reducing effects of self-employment differed based on poverty measure and threshold. The poverty-reducing effects are more prominent in poverty severity than incidence and intensity, and the magnitude of the impact is largest when poverty is measured at $1.90 a day as against $3.20 and $5.50 a day. Finally, the poverty-reducing effects of female self-employment are lower than their counterparts.Practical implicationsFirst, poverty-mitigating strategies in developing countries are advised to recognise self-employment as an essential tool to alleviate poverty. Consequently, alongside supporting the existing self-employed, policy focus should be on creating more and better self-employment opportunities for the poor. Second, rather than using generic measures to mitigate poverty, interventions specific to poverty measures and thresholds might ensure the maximum impact of such interventions. Third, gender-specific rather than gender-neutral labour market policies in addressing poverty are advised.Originality/valueTo the best of the author's knowledge, this is the first study to examine the empirical relationship between self-employment and poverty. As such, it makes novel contributions to both labour and development economics.

Our world is becoming more and more interested in virtual city modeling. This trend coincides with the need to better understand the spatially related problems and issues visually. With the increase types of information that can be linked spatially, and also, the increase size of population and buildings, better city planning to manage the third dimension is becoming a necessity. Meanwhile, 3D virtual city models do not have to be accurate but well representing the reality. Thus the paper is presenting a simple procedure to follow for a study area to show the effectiveness of such approach in 3D modeling for Cadastral, real estate evaluation purposes.


The key of the blurred image blind restoration is the estimation of the point spread function and non-blind deconvolution algorithm.For the problem of the image blur which low SNR and small blur length caused by the camera shake,a fast robust algorithm is proposed to estimation the parameters of blur kernel function.Then the blurred images are restored by using a fast non-blind deconvolution method.Compared with R.Fergus' algorithm,the experiment results prove that the algorithm for motion blurred by the relative linear movement has faster speed and good recovery effect.


years. When the Institute of Family Therapy was set up independently of the Institute of Group Analysis in London a number of people felt that this reflected a lusty striving for autonomy on the part of the Institute of Family Therapy of the kind that accompanies healthy adolescent maturation. Others felt that the break first and foremost reflected a significant differentiation of theoretical frames of reference. My own impression of this evolutionary process, inevitable as it may be, is that some valuable conceptualizations are liable to be jettisoned en route, either because of the narrowed

A prototype shelter was designed to withstand a blast loading corresponding to a 10.0 psi (68.9 kPa) incident overpressure. The hardened shelter was then constructed, instrumented and subjected to a simulated nuclear blast loading. Test results demonstrated that a design featuring shear stiffened sandwich panels with aluminum face materials could withstand a nominal 10.0 psi incident shock loading.


The lack of an initial condition is one of the major challenges in full-wave-equation depth extrapolation. This initial condition is the vertical partial derivative of the surface wavefield and cannot be provided by the conventional seismic acquisition system. The traditional solution is to use the wavefield value of the surface to calculate the vertical partial derivative by assuming that the surface velocity is constant. However, for seismic exploration on land, the surface velocity is often not uniform. To solve this problem, we propose a new method for calculating the vertical partial derivative from the surface wavefield without making any assumptions about the surface conditions. Based on the calculated derivative, we implemented a depth-extrapolation-based full-wave-equation migration from topography using the direct downward continuation. We tested the imaging performance of our proposed method with several experiments. The results of the Marmousi model experiment show that our proposed method is superior to the conventional reverse time migration (RTM) algorithm in terms of imaging accuracy and amplitude-preserving performance at medium and deep depths. In the Canadian Foothills model experiment, we proved that our method can still accurately image complex structures and maintain amplitude under topographic scenario.

When parsing images with regular spatial layout, the location of a pixel (x,y) can provide important prior for its semantic label. This paper proposes a novel way to leverage both location and appearance information for pixel labeling. The proposed method utilizes the spatial layout of the image by building local pixel classifiers that are location constrained, i.e., trained with pixels from a local neighborhood region only. Albeit simple, our proposed local learning works surprisingly well in different challenging image parsing problems, such as pedestrian parsing and object segmentation, and outperforms state-of-the-art results using global classifiers. To better understand the behavior of our local classifier, we perform bias-variance analysis, and demonstrate that the proposed local classifier essentially performs spatial smoothness over the global classifier that uses appearance information and location, which explains why the local classifier is more discriminative but can still handle mis-alignment. Meanwhile, our theoretical and experimental studies suggest the importance of selecting an appropriate neighborhood size to perform location constrained learning, which can significantly influence the parsing results.

The Internet of Things (IoT) confronts several security threats due to the abundance of tiny computer devices. In this paper, we develop an intrusion detection system (IDS) based on selection and classification of features, two machine learning approaches to improve the security of the Internet of Things. Feature selection was successful thanks to the relatively low computational complexity of the filter-based method. Compare feature classification algorithms used in six machine learning algorithms and in those algorithms, we found the best approach for our system. The system ultimately settled on the Decision Tree (DT) algorithm because to its superior performance and accuracy of around 99 percent across various data sets.

This paper is aimed to evaluate the existence of wormholes in viable [Formula: see text] gravity models (where [Formula: see text] is the scalar curvature and [Formula: see text] is the trace of stress–energy tensor of matter). The exact solutions for energy–momentum tensor components depending on different shapes and redshift functions are calculated without some additional constraints. To investigate this, we consider static spherically symmetric geometry with matter contents as anisotropic fluid and formulate the Einstein field equations for three different [Formula: see text] models. For each model, we derive expression for weak and null energy conditions and graphically analyzed its violation near the throat. It is really interesting that wormhole solutions do not require the presence of exotic matter — like that in general relativity. Finally, the stability of the solutions for each model is presented using equilibrium condition.


The 3.1-3.0 Ga tonalite-trondhjemite-granodiorite rocks of the Middle Dnieper craton were exposed in the provenance of meta-terrigenous rocks of the Hleyuvatka Suite, which forms the upper part of the Krіvоi Rog-Kremenchuk structure. In addition, 3,2; 3,3-3,4 and 3,5-3,7 Ga gneisses were also present in the source area as well as the 2,87-2,85 Ga potassium-sodium granites. Among the Paleoproterozoic detrital zircons, five grains yielded an age of 2,14-2,09 Ga, which indicates the presence of Paleoproterozoic granites in the provenance. The maximum depositional age of the metamorphosed terrigenous rocks of the Hleyuvatka Suite is thus about 2,1 Ga. These data gives ground to distinquish the Hdantsivska and Hleyuvatka suites as a separate Series .


While a full discussion of nomograms requires the use of determinants and other ideas beyond the School Certificate stage, many practical needs can be met using two simple types. These can be understood and applied with only a knowledge of similar triangles; and, besides being of interest in themselves, produce as a by-product a working knowledge of logarithmic and other scales. Before considering the method of construction, use of one or two types should be made by the pupil. This will help him to appreciate their simplicity. Their practical value, too, becomes apparent by using types (e.g. the focal length of a lens) that tie up with his work in the laboratory. Construction on squared paper can be done quickly and with fair accuracy. One or two carefully done examples with subdivisions inserted should be attempted also.


The present paper reviews the available research on the effects of drug interventions with young hyperactive children. Following a brief discussion of hyperactivity in young children, several studies pertinent to the difficulties involved in the early identification of hyperactive behaviors and the drugs typically used in the management of such behaviors are summarized. It is concluded that the limited number of investigations does not justify the widespread utilization of stimulant drug treatment with young hyperactive children. Implications for future research and clinical practice are also discussed.


By using EAG instrument and "Y" pipe,this study examined the EAG responses of Anoplophora glabripennis adults to 12 kinds of plant volatiles,including cis-3-hexen-1-ol,β-myrcene,phellandrene,3-carene,S-α-pinene,camphene,R-α-pinene,S-β-pinene,D-limonene,ocimene,ethyl acetate,and hexane at 5 concentrations,and the behavioral responses of the adults to 9 kinds of the volatiles,aimed to provide basic information for the development of attractants and repellents to A.glabripennsis.The antennae of the female and male adults had obvious EAG responses to 12 kinds of the volatiles(except for the male adults to S-α-pinene),especially at the concentrations of 0.4 and 2 mol·L-1.There exited significant differences(P0.05 or P0.01) in the feeling strength of the antennae to the volatiles between female and male adults.The results of behavior test showed that higher concentrations ocimene and β-myrcene had obvious repellent effect(P0.01)(except myrcene to the female adults),S-α-pinene,S-β-pinene,ethyl acetate,R-α-pinene,phellandrene,and camphene had obvious attracting effect(P0.01)(except S-α-pinene to the male adults and camphene to the female adults),whereas D-limonene had no obvious repellent and attracting effect on the male and female adults.


This paper describes a GPS-based real-time remote safety monitoring system developed to address some of the critical safety issues related to commercial vehicles and buses, such as trucks, long-distance buses, expressway buses, and dangerous goods vehicles. The main idea behind the proposed system is to transform the conventional passive way of accidents management to an active way of eliminating the potential safety hazards arising in vehicle operations. Specifically, the proposed system involves equipping each fleet vehicle with an OBD (on-board device) to obtain real-time data on the vehicle's operating state, such as position, speed and direction. The collected data are sent to the fleet operations control center through wireless communication network, which can in turn send warnings or alerts to the driver had any incorrect maneuver or impending hazards been detected. This paper provides a detailed discussion about the architecture, components, and functionality of the system. The proposed safety monitoring system has been implemented and field tested in Chongqing, China, which has demonstrated its effectiveness in gathering valuable operational data and reducing vehicle road accidents.

Utilizing data from quinquennial industrial censuses for the period 1960-1975, this study examines economies of scale in a number of Mexico's manufacturing industries. A cross-sectional approach is used to estimate production functions by industry for each of four industrial censuses. In contrast to findings of relatively constant returns to scale for the United States, the Mexican data reveal substantial economies of scale at both the beginning and the end of the study period, suggesting that further opportunities for reduction in long-run costs exist. The resultant policy implications are that measures which promote larger scale manufacturing (incentives for expanded domestic production, export promotion, and selected tariff preferences) will speed up both short-term recovery and long-term growth of the Mexican economy. It is desirable, however, that these policies be harmonized with other designed to reduce the environmental contamination and congestion that has accompanied Mexico's industrial development.


Mental health conditions tend to go unrecognised and untreated in adolescence, and therefore it is crucial to improve the health and social outcomes for these individuals through age and culturally appropriate interventions. This paper aims firstly to describe the development and implementation of the HYPE project platform (a research and resource platform co-designed and co-produced with young people). The second aim is to describe the characteristics of participants who engaged with the platform and an embedded pilot online survey. A mixed methods design (including focus groups and repeated measures surveys) was used to address aims of the HYPE project. Data were analysed using thematic analysis and descriptive statistics to: (1) help improve access to health and social services, (2) guide provision of information of online resources and (3) deliver complementary community-based events/activities to promote mental health and to ultimately prevent mental health issues. Pilot and main phases of the HYPE project demonstrated the capacity and feasibility for such a platform to reach local, national, and international populations. Analyses demonstrated that the platform was particularly relevant for young females with pre-existing health difficulties. Some of the barriers to involving young people in research and help-seeking are discussed.


Most previous work in unsupervised semantic modeling in the presence of metadata has assumed that our goal is to make latent dimensions more correlated with metadata, but in practice the exact opposite is often true. Some users want topic models that highlight differences between, for example, authors, but others seek more subtle connections across authors. We introduce three metrics for identifying topics that are highly correlated with metadata, and demonstrate that this problem affects between 30 and 50% of the topics in models trained on two real-world collections, regardless of the size of the model. We find that we can predict which words cause this phenomenon and that by selectively subsampling these words we dramatically reduce topic-metadata correlation, improve topic stability, and maintain or even improve model quality.

The self-adhesive waterproof coiled material provided by the invention has excellent self-adhesive property.


This article envisions insurance through the ways in which it comes to inhabit the dailiness of people's lives. Insurance is usually constituted as a technology of risk. Rather than holding risk and insurance to the bare provisions of finance and financial forms, this article tangles with the affective attachments that grow out of insurance technologies. It investigates the place of these attachments (insurance fantasies) and the intimacies that effloresce from these attachments.


The purpose of this study was to describe the emotional distress of women (N = 300) and husbands (N = 265) prior to the women's breast biopsy and to identify factors related to their levels of distress. Standardized instruments were used to measure social support, uncertainty, marital satisfaction, family functioning, concurrent stress, hopelessness, and emotional distress. Women reported moderately high levels of emotional distress and significantly more distress than their husbands. Forty-two prevent of the variance in women's distress scores and 42% of the variance in husbands' distress scores were accounted for by the independent variables. Concurrent stress, lower education, hopelessness, and uncertainty explained the most variance in women's distress, while concurrent stress, hopelessness, and family functioning explained the most variance in husbands' distress.


In 2003 Kanehara Hitomi was awarded the Subaru Prize for her novel Hebi ni piasu I Snakes and Earrings. The same year the novel won Kanehara the well known Akutagawa Sho, making her and Wataya Risa the youngest writers ever to receive the prestigious prize. The following article is intended as an introduction into Kanehara's world of juvenile urban subculture, identity search and obsessive human relationships; it comments on her main motives (e.g. on the beautiful boy without mercy), her inclination for sadomasochistic constellations and on her recent ambitions as a "bad girl" who writes against the mechanisms of contemporary Japanese society.


Jiangsu is the earlier province into aging,the proportion of 60 and older elderly population has reached 17% in 2009.With the quick development of industrialization,urbanization and the aging process,the center of population aging will turn into cities from rural areas.The survey data of Jiangsu in 2009 indicated that the psychological status and spiritual life of urban elderly is good in general,but it does not adapt to the quick development of economy and society,the elderly requirements,the construction of harmonious society and the propulsion of healthy aging.It is very necessary to strengthen the recognition of the importance of elderly spiritual support and family care and then take various measures to further enhance the elderly spiritual cultural life and psychological health level.

In 4 (2.8%) of patients a peritonitis progress was noted after truncal vagotomy and ulcer excision conduction without the infection-toxical shock signs.


The Bureau of Mines conducted laboratory tests to investigate the ease of frictional ignition with frozen (nonrotating) conical bits cutting into sandstone. The number of strikes with a new bit to obtain ignition of a combustible methane-air environment was measured. Tests were made with bits tipped with both tungsten carbide and steel at several bit attack angles (angle between bit axis and sandstone surface) and initial tip angles (included angle at the tip of the new bit). Carbide-tipped bits required more strikes for ignition than steel-tipped bits by a factor of 7 to 10.


ABSTRACT
Two segments of breakfast cereal consumers, previously identified using conjoint analysis as "Healthy Choosey" and "Basic," were investigated using focus group methodology. The objective of this study was to investigate the attitudes, opinions and concerns of the two largest consumer segments of ready-to-eat (RTE) cereal.

Focus groups, consisting of four to seven participants each, were conducted in triplicate for each of the two segments. Participants met and discussed issues relating to RTE cereal and soy as an ingredient. The Healthy Choosey segment was more concerned with healthy ingredients and sensory acceptance, and was generally not negative to soy, whereas the Basic segment was more concerned about the basic nutrition, price and sensory acceptance, and was either neutral or negative toward soy. Our research indicated that RTE cereal manufacturers should focus on improving consumer acceptance to satisfy both segments of consumers. There is a need to promote the healthfulness of soy-based products without compromising the taste or the cost.

PRACTICAL APPLICATIONS
Our findings illustrated that conjoint analysis can be used in segmenting consumers who can then be recalled for further qualitative analysis. The concerns and needs among different segments of healthy breakfast cereal (HBC) consumers found in our study can be readily transferred to the commercial sector. Depending on the marketing strategy of the company, new or improved version of existing products can be made to satisfy one or more segments of consumers. Manufacturers of soy-based HBC are faced with less forgiving consumers who are reluctant to try soy products. Thus, new soy-based HBC should be introduced only when the products are rated at par with nonsoy-based HBC in terms of sensory acceptance. Hype marketing of soy products is a turnoff to consumers and soy-based HBC manufacturer should focus on promoting only basic, well-established health findings.

Three-dimensional Delaunay triangulation are the most common form of three-dimensional triangulation known, but they are not very suitable for tetrahedral finite element meshes because they tend to contain poorly shaped sliver tetrahedra. In this paper, we present an algorithm for constructing improved-quality triangulation with respect to a tetrahedron shape measure. This algorithm uses combination of two or more local transformations to improve a given triangulation toward an optimal triangulation. Experimental results on finite element meshes show that this algorithm is much more effective than previous methods at removing slivers from Delaunay triangulation and producing nearly optimal triangulation. A variation of this algorithm for improving a pseudo locally optimal non-Delaunay triangulationn toward a Delaunay triangulation is also presented.


A micropropagation protocol for parthenocarpic gynoecious cucumber reduces the burden of producing the seeds for each generation and their maintenance in-vivo. Thus an experiment was conducted in order to regenerate the plants in-vitro to check their performance after micropropagation. The micropropagation resulted in maximum shoot initiation (100%) from seedling excised cotyledonary explants with half strength MS medium supplemented with 0.5 mg/l IAA and 2 mg/l BAP along with half strength MS medium supplemented with 0.25 mg/l IAA for rooting and from stem nodal explants with Full MS + 1.5 mg/l IAA + 2 mg/l BAP media whereas half strength MS media without any hormones resulted in rooting and in both cases there were in-vitro flowers and change in their sex expression while grown in in-vivo conditions. On an average 61.11 and 48.15 percent survival was recorded from the plants regenerated through cotyledonary explants Original Research Article Bhardwaj et al.; CJAST, 39(4): 17-24, 2020; Article no.CJAST.55013 18 and stem nodal explants respectively. Out of five survived plants from regenerated parthenocarpic genotype CS 131 three showed monoecious sex expression and two exhibited gynoecious (parthenocarpic) sex expression. Mixed response of sex expression was evident in the regenerated parthenocarpic and gynoecious genotypes.


Abstract The root distribution of Commiphora pyracanthoides Engl., a potential encroaching woody species in the sweet bushveld areas of the Northern Province, South Africa, was studied at the Mara Agricultural Development Centre. The root system of ten C. pyracanthoides shrubs consisted of a taproot system supported by a well developed fleshy secondary root system. Minimum branching of secondary roots occurred, resulting in the absence of tertiary and feeder roots. Weak relationships existed between root distribution, plant height and canopy diameter, but subjectively estimated, secondary roots extended horizontally at an average depth of 15 ‐20 cm to a distance of more or less 1–1.5 times the canopy diameter and 1.5–2 times tree height. It is proposed that the correct placement of soil‐applied arboricides and/or absorption mechanisms may be critical for effective chemical control of C. pyracanthoides.


Through analyzing the SSTA in Nino3 sea area and the southern oscillation index (SOI) from 1948 to 2001, this paper determines the starting and ending years and months of the cold and warm events in the ENSO cycle.


Six pairs of Stokes-anti-Stokes lines of stimulated four photon mixing in a multimode fiber with GeO_2+P_2O_5 doped silica core are simultaneously recorded. A continuum band generated jointly by SFPM and stimulated Raman scattering is obtained in the spectral range 540-640 nm. On the basis of two different experiment results for 20 m and 200 m fiber, the mechanism of competition and transformation between SFPM and SRS are analyzed in some detail.


A hybrid Reynolds Averaged Navier-Stokes (RANS)/Large Eddy Simulation (LES) model based on the k equation is proposed with the quadratic stresses to stimulate the quick growth of resolved turbulence around the RANS/LES interface and remove the artificial buffer layer. The proposed hybrid model is applied to simulate the Taylor-Couette (TC) flow with different RANS/LES interface locations and Taylor numbers. The model is verified by comparing with the direct numerical simulation results and validated by experimental torques with different Taylor numbers. The model is insensitive to the interface location owing to the effect of the quadratic stress in adjusting the energy backscatter. By means of the proposed model, the shift of the mean velocity profile around the RANS/LES interface is diminished. It is revealed that the contribution of the Reynolds shear stress to transporting angular velocity in the annular gap center region rises from 20% to 50% as the radius ratio reduces from 0.909 to 0.5 in the TC fl...


Background: This in vitro study was conducted to compare the effect of universal bonding application strategy (i.e., self-etch and etch-and-rinse) on marginal adaptation of bulk-fill and conventional composite resins in Class II restorations. Materials and Methods: In this in vitro study sixty sound premolars extracted for orthodontic reasons were selected. The samples were allocated to four groups based on the universal bonding application strategy (self-etch and etch and rinse) and type of composite (bulk-fill and conventional). In each group, boxes were prepared with a depth of 4 mm on the mesial surfaces. Finally, the marginal adaptation of the samples was evaluated under a stereomicroscope. Two-way ANOVA was used to compare the marginal adaptation data in the study. Statistical significance was set at P < 0.05. Results: Considering the type of universal bonding application strategy, there was a statistically significant difference in marginal adaptation. Etch-and-rinse strategy showed better marginal adaptation compared to self-etch strategy (P < 0.001). However, there was no statistically significant difference in marginal adaptation between the two composite resins (P = 0.829). Furthermore, the interaction between the two factors (type of universal bonding application strategy and type of composite resin) was not statistically significant (P = 0.629). Conclusion: Etch-and-rinse bonding application strategy in both the bulk-fill and conventional composite resins exhibited better marginal adaptation compared to self-etch bonding application strategy. However, the difference of marginal adaptation between the two types of composite resins (bulk and conventional) was not significant.


Nano composite based on polyaniline (PANI)
nano fibers filler and chromic acid functionalized low
density polyethylene (LDPE) matrix with biocompatibility
and low percolation threshold value was prepared via twin
screw extrusion process. Density measurement, Fourier

reported. As low density polyethylene functionalization
renders LDPE more biocompatible, it also facilitates
conductivity due to carbon carbon double bonds, sulfonic,
and carbonyl group moieties. PANI nano fibers also assist
in charge transfer mechanism of resultant composite.
Overall results indicate the formation of highly stable
nanocomposite materials, with good physiochemical
properties and conductivity. The resultant blend may prove

Abstract This article focuses on the way Taiwanese activists used environmental justice (EJ) as a rhetorical tool to promote their campaigns and to fight against each other. In order to highlight the arguments from both sides, the anti-national-park movement is examined in depth. In this specific case, the concept of EJ has been advanced along two paths: for indigenous rights advocates, EJ is about protecting indigenous peoples' traditions and livelihoods; environmentalists however insist that EJ refers to protecting the environment for future generations or for its own sake. Since making compromises is seen as accommodating injustice/evils, the Taiwanese EJ movement ends in stalemate. It argues that unless activists break the present deadlock, the government may gradually take the initiative and redefine EJ to meet its own ends. For the further development of the Taiwanese EJ movement, that is undoubtedly something we should avoid.


The terrestrial laser scanning technology is increasingly applied in the deformation monitoring of tunnel structures. However, outliers and data gaps in the terrestrial laser scanning point cloud data have a deteriorating effect on the model reconstruction. A traditional remedy is to delete the outliers in advance of the approximation, which could be time- and labor-consuming for large-scale structures. This research focuses on an outlier-resistant and intelligent method for B-spline approximation with a rank (R)-based estimator, and applies to tunnel measurements. The control points of the B-spline model are estimated specifically by means of the R-estimator based on Wilcoxon scores. A comparative study is carried out on rank-based and ordinary least squares methods, where the Hausdorff distance is adopted to analyze quantitatively for the different settings of control point number of B-spline approximation. It is concluded that the proposed method for tunnel profile modeling is robust against outliers and data gaps, computationally convenient, and it does not need to determine extra tuning constants.

This paper describes the protection that Spanish law dispenses human life in the pre-birth, paying particular attention to constitutional protection and liability claims resulting from injuries to the conceived.


Background: A substantial body of experimental and epidemiological evidence has been accumulated suggesting that stressful events in early life including acute perinatal stress, maternal deprivation or separation, and variation in maternal care may lead to neuroendocrine perturbations thereby affecting reproductive performance, cognitive functions, and stress responses as well as the risk for infectious, cardio‐metabolic and psychiatric diseases in later life. Results: Findings from recent studies based on both genome‐wide and candidate gene approaches highlighted the importance of mechanisms that are involved in epigenetic regulation of gene expression, such as DNA methylation, histone modifications, and non‐coding RNAs, in the long‐term effects of exposure to stress in early life. Conclusions: This review is focused on the findings from human studies indicating the role of epigenetic mechanisms in the causal link between early‐life stress and later‐life health outcomes.

This study was done to determine if any significant correlation existed between students' entrance exam scores on the COMPASS-Reading test and their ensuing success in the general education English course, Written Communication, at Chippewa Valley Technical College (CVTC). Students were identified fiom the Written Communication course enrollment at CVTC, fall of 2003 through spring of 2006. To ensure the student data for correlation was relatively equal the selection of students was limited to a student's first time enrollment, and those enrolled in traditional delivery, semester long sections of Written Communication. The students also had to have an academic outcome in Written Communication and a COMPASS-Reading entrance exam predictor score. CVTC's IT Department identified 2,695 students during this timefiame that met the criteria for correlation. The data was provided to UW-Stout's Budget, Planning and Analysis office for correlation. Ultimately, of the 2,695 students 1,941 were identified for correlation as being enrolled in the course for the fist time, having a COMPASS-Reading Score, and having an academic outcome in Written Communication. The Pearson's-r two-tailed correlation outcome found a coefficient o f . 137, or a finding of no linear relationship between the COMPASS-Reading score and the academic success of a student in Written Communication. The finding proved the null hypothesis of no relationship of statistical significance, meaning the COMPASS-Reading score is not a good indicator for predicting student success in Written Communication.

The twenty-first century is teeming with larger-than-life threats to our larger-than-life existence, such as famine, war, natural disasters and climate change, viruses, incurable disease, etc. At stake is the future of the human species as a whole. But it is not just external threats that herald the prospective end of humanity. We also face the general exhaustion of many of our earlier and more comfortable modes of philosophy. This is arguably a much graver threat. It is this gloomy atmosphere that the philosophy of antinatalism taps into. Antinatalism is the philosophical view according to which human reproduction should be brought to a halt for any of a variety of reasons. It will be argued here, however, that we can only come to the antinatalist conclusion when we affirm that humankind (somehow) represents a very persistent anomaly in the universe at large. Otherwise, we could simply resort to (much) less radical steps than the ones advocated by antinatalism. Based on this, an important distinction will be made between reactionary (or activist) antinatalism and its more philosophical, so-called originary, counterpart. Ultimately, against recent attempts that push for a moderate embrace of antinatalism, the present work makes a strong case for it. It is argued that this is warranted by the very writings most usually associated with this radical philosophical position.

Ascorbate peroxidase (APX) plays an important role in the metabolism of hydrogen peroxide in higher plants. We studied the effect of over-expressing a Populus peroxisomal ascorbate peroxidase (PpAPX) gene under the control of the cauliflower mosaic virus 35S promoter or the rd29 promoter in transgenic tobacco. High levels of PpAPX gene expression were observed in 35S-PpAPX transgenic plants, with a 50% increase in APX activity. The constitutive expression of PpAPX in the tobacco exhibited no morphological abnormalities, while significantly increased root growth was observed in transgenic plants, when compared to control plants. Several independently transformed lines were propagated and evaluated for resistance to methyl viologen (MV), drought and salt stress. Visual assessment of transgenic and control lines exposed to MV (50 or 100 μmol) confirmed that over-expression of APX minimized leaf damage. APX activity was nearly 80% higher in the leaves of transgenic plants in response to drought or salt stresses. Moreover, the transgenic tobacco also showed significantly improved drought resistance and salt tolerance at the vegetative stage. RNA blot analysis indicated that the PpAPX transcript level was very low under normal growing conditions in rd29Ap-PpAPX plants, but clearly increased under drought stress. Our results show that PpAPX does not play a significant role under normal growing conditions, but did ameliorate oxidative injury under abiotic stress. The Ad29 promoter should be used as an inducible promoter in transgenic works.

Abstract. Hernawati, Zuhud EA, Prasetyo LB, Soekmadi R. 2022. Synopsis of Sumatran Nepenthes (Indonesia). Biodiversitas 23: 4243-4255. Taxonomic status is a fundamental component in determining the conservation status of a species. Inappropriate taxonomic entities can mislead efforts to protect species, especially endangered ones. Determining the taxonomic status of Sumatran Nepenthes is an essential step in conserving these unique species. This study aims to assess the taxonomic status and update the compilation of scientific names and taxon positions related to the Sumatran Nepenthes. The morphological characters were collected through observation of herbarium specimens and field research in several locations in Sumatra. The grouping of species is built based on the similarity of morphological characters for each selected species and follows a taxonomic revision process. The results showed that Sumatra had 39 species of Nepenthes, which were previously known to occur in only 29 species. The increase in the number of Sumatran Nepenthes came from (i) The publication of 9 new Nepenthes species from Sumatra. (ii) Restores N. pectinata and N. xiphiodes as independent species from their original position as synonyms for N. gymnamphora. (iii) Positioning N. gymnamphora as one of the Nepenthes species on the island of Java. (iv) Positioning N. angasanensis, N. longifolia, N. talangensis, and N. tenuis as independent species and not synonyms of N. mikei, N. beccariana, N. bongso, and N. dubia


Dynamic voltage scaling (DVS) has been widely adopted in multicore SoCs for reducing dynamic power consumption. Despite its benefits, the use of DVS increases test time because high product quality can only be ensured by testing every core at multiple supported voltage settings; hence the repetitive application of the same or different tests at multiple voltage settings becomes necessary. In addition, testing at lower supply voltage settings increases considerably the length of each test because lower scan frequencies must be used for shifting test data using scan chains. Standard scheduling techniques fail to reduce the test time for DVS-based SoCs since they do not model testing at multiple voltage settings. In addition, they do not consider the practical aspects of tester overhead and the dependencies between core voltage settings due to the use of voltage islands. To alleviate the detrimental impact of DVS on test application time, we propose a time-division multiplexing (TDM) method and an integer linear programming-based test scheduling technique, which exploit high automatic test equipment (ATE) frequencies even when low shift frequencies must be used at low voltage settings. Experimental results on two industrial SoCs highlight the effectiveness of TDM and the associated scheduling method.


PurposeThe boom in live streaming has intensified competition among streamers for viewers' gifts, which makes it meaningful to study the factors that affect the viewers' gifting behavior. Given the emotional attachment between streamers and viewers, the authors set out to elucidate a new driver on viewer gifting: expressions of the streamer. This research aims to explore the impact of streamer emotions on the viewer gifting behaviors, including free and paid gifting. The loyalty level of the viewers is also introduced as a moderating factor to investigate the heterogeneous effect of streamer emotions on gifting behavior.Design/methodology/approachThe dataset the authors collected consists of two parts, including 1809.69 h of live streaming videos and 358,002 gift giving records. Combined with deep learning methods and regression analysis, the authors performed empirical tests on the 81,110 valid samples. Several robustness checks were also conducted to ensure the reliability of main results.FindingsThe empirical results show that streamer emotions do have effects on viewers' free and paid gifting behavior. The authors' findings show that positive streamer expressions, such as happiness and surprise, have a positive influence on viewer gifting behavior. However, some negative expressions, like sadness, can also have a positive impact. Moreover, the authors discovered that higher viewer loyalty amplifies the positive effect of streamer emotions and reduces the negative effect.Originality/valueThis research contributes to the study about streamer emotions and viewers' consumption behavior, which extends the application of emotion as social information model (EASI model) in the live streaming setting. The authors carefully divide the gifting behavior into two types: free and paid, and study how these two types are affected by streamer emotions. Besides, these effects are analyzed within viewers of different loyalty levels. This study offers practical emotion management strategies for streamers and live streaming platforms to gain more economic profits.


Assessment of bone condition using ultrasound based on pulse echo (PE) technique is preferred because the usage of single transducer. The objective of this paper is to conduct an experiment using PE technique to examine the correlation of fast and slow wave attenuation with various porosities of polyurethane (PU) foam. The waves are decompose using bandlimited deconvolution methods. It observed that the fast wave required sufficient thickness of solid structure to interact well. Despite suffer interference with unwanted scattered wave, the reflected fast and slow wave which propagates twice through the bone models and have enough interaction with the internal structure may contribute to the moderate and constant correlation coefficient for every thickness (fast wave, $R_{\text{average}}^{2}=0.58$ and slow wave, $R_{\text{average}}^{2}=0.70)$.


ABSTRACT
Soluble solid leached out during soaking and cooking of food legumes generally decreases the overall quality of the final products. Solid loss behavior of whole chickpea during soaking and cooking in water was investigated at 20, 30, 50, 70, 85 and 100C. The amount of solid loss and its rate increased with increasing temperature, and the former was 2.3% at 20C and 10.2% at 100C at the end of the process. Carbohydrates and proteins composed of 80–91% of the solid lost. A zeroth-order kinetic model fit the solid loss data. The solid loss rate constant (kds) increased with temperature, and it was 4.7 × 10−5/s at 20C and 240.3 × 10−5/s at 100C. Effect of temperature on kds was determined using an Arrhenius-type equation. The Arrhenius plot exhibited two linear lines crossing at the gelatinization temperature (61C) of the whole chickpea. The activation energy was determined to be 59.5 and 22.6 kJ/g/mol above and below the gelatinization temperature, respectively.

PRACTICAL APPLICATIONS
Soaking and cooking are the two main steps during processing of chickpea. Soluble solid loss into the soaking or cooking water generally decreases the nutritional and economic value of the final product and it is one of the quality indicators of the dry, soaked and soaked/cooked legumes. In the current study, soluble solid loss from whole chickpea seeds during soaking and cooking in water were studied as a function of time and temperature. Results from the current study can be useful in designing the process parameters of soaking and cooking and for the evaluation of the quality of dry or processed whole chickpea.

An air fryer is a kitchen appliance that works by using high speed hot air circulation. When the fryer is working, it begins to produce hot air and a mechanical fan begins to circulate it very fast around the food, which fries the food and produces a crispy layer. Most hot air fryers come with adjustable temperature and timer knobs that allow for more precise cooking. Food is cooked in the cooking basket that sits on a drip tray. There are various brands of air fryers that claim to fry the food with 80% less oil in general. Air fryer technology is based on "Rapid air technology" that uses the hot air to fry and cook the food which causes the use of less oil frying food. Which food needs what amount of cooking time. Time is a business which has not been dealt with properly. In most of the cases the user is compelled with a restricted amount of control. Most of the people wouldn't have noticed (but can reason out very well) different type of food need different amount of cooking time which depends directly on the air temperature and fan speed etc.


The central scope of the present study is to investigate the inflows of the distinction between positive contractual interest and negative contractual interest on the delimitation of indemnity in the context of termination of the contract for culpable default. To this end, it is investigated, initially, the meaning that the word interest assumes in the dogmatic of the civil liability. From understanding the meaning of contractual interest, the study seeks to examine the meaning and scope of the distinction between its two modalities – positive and negative interest –, with particular focus on the controversy regarding the definition of the modality of contractual interest to be to guide the indemnity within the scope of the contractual resolution for breach. Other relevant controversies are also examined, notably those concerning the possibility or not of cumulation between the positive and negative interests, the possibility or not of the victim's free choice between one and the other species of contractual interest and, finally, the limitation or not of the negative interest by the positive interest.


introduces gallbladder carcinoma into the differential diagnosis—a rare disease best managed by an experienced oncologic surgeon. A 68-year-old Japanese gentleman presented with weight loss, anorexia, and abdominal discomfort. He had been on chronic opioid use for the last decade for back pain secondary to degenerative joint disease. His pain was not associated with meals, time of day, or any identifiable inciting factors. CT scan of the abdomen revealed a large stone in the neck of the gallbladder (small arrow) with marked irregularity along the superior portion of the organ suggesting a neoplasm (large arrow, panel A). A transabdominal ultrasound revealed a 3 cm echogenic stone in the lumen, a thickened gallbladder wall measuring up to 1.2 cm in maximum diameter, and focal irregular thickening of the wall adjacent to the liver read by the radiologist to be consistent with neoplasm. White blood cell count, liver function tests, CEA, and Ca19-9 were within normal limits. The patient was

By predicting from learned experiences and filtering current multi-resolutional data achieves optimal filtering control under dynamic uncertainty.


Models for bacterial and viral infections and intoxication were developed in rhesus macaques (Macaca mulatta). Manifestations of acute-phase illnesses, e.g., temperature, white blood cell (WBC) counts, blood cultures, etc., were monitored at regular intervals. Viral infection was established by inoculating subcutaneously 412 plaque-forming units of Trinidad strain, Venezuelan equine encephalomyelitis virus. A diphasic febrile response developed, with the first fever peak on days 1 to 2 and a second peak on days 3 to 5. Viremia occurred within 12 hours and persisted in some animals for as long as five days. WBC responses were typical of viral infection. Gram-positive infections were induced by intravenous (IV) inoculation of 108 Type I Diplococcus pneumoniae. Peak febrile response and bacteremia (102 to 106 pneumococci per milliliter) occurred within 48 hours. Gram-negative infections, obtained by IV inoculation with 109Salmonella typhimurium, induced maximal febrile responses within 24 to 48 hours. Leukopenia occurred in 75% of animals; all were bacteremic. Mortality was 40% at 72 hours. Manifestations of intoxication following IV administration of purified staphylococcal enterotoxin B (10 μg per kg body weight) consisted of vomiting, diarrhea, leukopenia, and fever within one to three hours and resembled nonlethal staphylococcal food poisoning of man. These studies indicate that the rhesus macaque has reproducible and characteristic responses to a variety of microbial stimuli and therefore is eminently suitable for studying pathophysiologic, metabolic, and immunologic parameters of infectious or toxic disease processes.

We propose a mixed formulation for non-isothermal Oldroyd-Stokes problem where the both extra stress and the heat flux's vector are considered. Based on such a formulation, a dual mixed finite element is constructed and analyzed. This finite element method enables us to obtain precise approximations of the dual variable which are, for the non-isothermal fluid flow problems, the viscous and polymeric components of the extra-stress tensor, as well as the heat flux. Furthermore, it has properties analogous to the finite volume methods, namely, the local conservation of the momentum and the mass.


A GENERAL THEORY IS PRESENTED FOR THE SAMPLING OF MATERIALS AND STATISTICAL POPULATIONS THAT ARE ENCOUNTERED IN THE FIELD OF ENGINEERING AND OTHER DISCIPLINES. THE BASIC CONCEPT OF THIS THEORY IS THAT THE VARIALBILITY OF A MATERIAL CONSIGMENT OR ANY OTHER POPULATION CAN BE EXPRESSED BY TWO VARIANCE COMPONETS THAT ARE CONSTANTS AND REFLECT STATISTICAL PROPERTIES OF THE MATERIAL IN THE SAME WAY THAT OTHER MATERIAL CONSTANTS REFLECT CERTAIN PHYSICAL AND CHEMICAL PROPERTIES OF MATERIALS. THESE VARIANCE COMPONENTS OR SAMPLING CONSTANTS ARE USED FOR DESIGNING SAMPLE EXPERIMENTS AND, MORE SPECIFICALLY, FOR DETERMINING IN ADVANCE THE PRECISION OF SAMPLING EXPERIMENTS AS A FUNCTION OF SAMPLE SIZE AND THE NUMBER OF INCREMENTS. APPLICATION OF THE METHOD IS ILLUSTRATED WITH 12 EXAMPLES THAT COVER A LARGE NUMBER OF MATERIALS AND CONDITIONS. CONDENSED INSTRUCTIONS ARE PRESENTED IN A TABLE. /AUTHOR/

In vitro spectral transmission measurements using excised human epidermis as the substrate were used to determine the photoprotection provided by physical and organic chemical sunscreens encompassing a wide range of sun protection factor (SPF). The measured SPFs were in good agreement with the quoted SPFs of the products. This in vitro technique using human epidermis could prove reliable for evaluating the SPF of high-protection sunscreens for which in vivo assay is problematic due to the impractically long irradiation times to achieve erythema on sunscreen-protected skin. We also compared our calculated SPFs, which assumed a natural sunlight spectrum, with those that would have been obtained assuming a xenon-arc solar simulator spectrum. We found that for products with relatively low UV-A absorption, the use of a solar simulator for in vivo testing overestimates the SPF that would be expected in sunlight.


The peel of the citrus grandis was extracted with alcohol at room temperature,and concentrated to dry. The crude extract was chromatographed on silica gel column eluted with Petroleum Ether,Ethyl acetate,N-Butanol,Methanol and H2O to gain bioactive components. The antioxidant activity of the extracts were studied by the DPPH system,the nitro blue tetrazolium(NBT) photo-reduction and Cyto(Ⅱ)-Cu2+ system. The results showed that all the extracts from the peel of citrus grandis have scavenging effect on DPPH free radical ,superoxide free radical and hydroxyl radical . The extract from the N-Butanol has the strongest effect on the DPPH free radical,and the extract from the methanol has the strongest effect on the superoxide free radical.


Novel communication platforms such as e-papers and e-textiles offer instant information and data handling access. These electronic platforms are based on smart materials that can recognize, process, and respond to external stimuli. They are also easy to manipulate and can be applied on surfaces of various types and shapes. Electroactive or intrinsically conducting polymers1 such as polyaniline, polythiophene, or polypyrrole that combine the electrical conductivity of a metal with the mechanical flexibility and processing properties of a polymer, hold great promise as smart materials for flexible plastic and wearable electronics.2 Unfortunately, degradation issues resulting from their low environmental, thermal, and electronic stability, as well as processing problems, affect their reliability and long-term operational functionality. To address these issues and improve their overall properties, novel nanoscale concepts aimed at adding functionality at the molecular level have generated significant interest. In this context, combining electroactive polymers with carbon nanotubes (CNTs) represents an attractive solution. These materials consist of tiny graphene cylinders of nanometer diameter and micrometer length with unique structural, mechanical, thermal, electronic and optical properties.3 However, simple mixing procedures usually fail to yield homogeneous and stable CNT dispersions, thus hindering effective interactions as well as further material processing. To overcome these problems, we used an in-situ approach in which the polymerization of the electroactive polymer was carried out in the presence of CNTs.4–6 The technique is based on the idea that the extended π-electron system of CNTs can serve as molecular templates to direct the growth of the polymer Figure 1. In-situ polymerization process for a polyaniline multi-walled carbon nanotude (MWNT) composite. Polyaniline is first obtained in the emeraldine salt form, which is conducting but not soluble. Subsequent deprotonation with ammonium hydroxide transforms the emeraldine salt into the emeraldine base form (which is not conducting but soluble).


Spatial information plays a very important role in image understanding. Fuzzy mathematical morphology provides an effective basis for extracting binary and ternary spatial relationships by creating a fuzzy landscape where the value at each point corresponds to the relationship degree according to its position with respect to the reference object(s). We improve existing morphological approaches in terms of flexibility and efficiency while also obtaining more intuitive results. Our morphological definitions are sensitive to relative visibility of areas based on partial occlusions, and can also cope with the cases where some objects extend significantly differently relative to others. We show the effectiveness of the proposed definitions using synthetic and real images.

Thermal-stress fatigue resistance of alloys Sel-1, B & B, forged Udimet 500, and Inconel 713 was studied at 1700 deg F in a J47 engine with an average of 11 hours at rated speed between starts. These data were compared with those of a previous investigation with an average of 1.4 hours of rated-speed operation between starts. The data include the number of starts to cause bucket cracking, the number of starts to crack 50 per cent of the buckets of each alloy group, and the mode and rate of crack progression to cause fracture of buckets.

The transport rate of liquid water, i.e., the water penetration rate, into paper is one of the important physical properties in the printing, coating, and gluing processes. However, some kinds of paper are too thin to permit the measurement of the penetration rate in the direction of the thickness accurately. Thus, a novel method for measurement of the penetration rate has been developed. The large difference in electrostatic capacitance between soaked and dry paper and that in penetration rate between filter and thin paper were utilized as the foundation for this method. The time required for penetration through the whole sheet of thin paper was calculated from the measured penetration curve on the basis of theoretical analysis. As a result of the measurements in a relative humidity range of 40 to 70% it was concluded that this method could be useful in the characterization of thin paper materials with respect to penetration.


Recently the geogrids are being used in some large projects such as Inchon International Airport construction, highway construction, and Korean High-Speed Railway construction with not only the merit of simple construction but also reinforcing efficiency for the soft ground. Main function of roadbed is to provide a stable foundation in terms of bearing capacity and settlement for the subballast and ballsat layers. Differential settlement of the railroad should be avoided. The cyclic laboratory model tests were performed to investigate the settlement behavior of geogrid reinforced railroadbed. The ratio of settlement of roadbed under cyclic loading with three layers of geogrid reinforced is less than 1/2 of the roadbed thickness without reinforcement.


In many application areas the power density of power electronic converter system is an important design criteria, which is often limited by the passive components and the cooling system. In order to decrease the size of the cooling system, a thermoelectric cooler (TEC) could be inserted between the semiconductor and the heat sink. With the TEC, the temperature drop across the heat sink could be increased so that the volume of the heat sink decreases. In case the ambient temperature is relatively close to the maximum admissible junction temperature, this volume reduction of the heat sink is larger than the additional volume required for the TEC and its power supply as will be shown in this paper. Furthermore, the influence of the TEC on the system efficiency is investigated and using the TEC for actively damping the junction temperature swing in systems with varying losses is discussed.

AIM
The purpose of this study was to compare muscle torque during isokinetic knee movements of patients after total knee arthroplasty (TKA) with a similar healthy group.

METHOD
43 patients were examined 3 years after primary total knee arthroplasty with an isokinetic dynamometer (Cybex 340). Torque measurements were evaluated for extension and flexion with 4 different velocities. The results were compared with a group of 43 people without knee disease. Bouth groups consist of 29 women and 14 men. The mean age was also comparable (66.4 vs. 65.8 years).

RESULTS
A mean peak torque of 65.9 Nm was measured during extension with low velocity (60 degrees /s) in the group of patients with TKA -- 84.3 % of the control group (p = 0.079). At the highest velocity the patients produced 30.2 Nm. This was 72.8 % of the control group (difference statistically significant, p = 0.006). No differences were found in the Extension/Flexion ratio between the two groups.

CONCLUSION
The deficites of knee strength in patients after TKA are more distinct in high velocities of motion.

In some large environments where humans and machines coexist, such as smart factories, restaurants, and hotels, multiple mobile robots system have certain advantages over single mobile robot in terms of task complexity, execution efficiency, and system robustness. However, path conflicts and blockages may occur among robots without effective global coordination method, especially in some special areas like narrow straight roads (N-S-R) and crossroads (C-R). To solve this problem, using the global topology map might be a good solution. Therefore, this paper proposes a method called Surplus Topology Generation Algorithm (STGA) for constructing a global topological map based on grid map representation. On the basis of grid maps, we designed Node-Filter to generate enough topological nodes, and simplified the node set by Node-Selection. In special areas such as N-S-R and C-R, which are prone to path conflicts and blocking scenarios, we extracted the Harris corner point and combined them to select the corner point combinations that characterize some special features like passage entrance, etc. Then, feature nodes that can characterize the special features were obtained by establishing mapping relationships between nodes and corner point combinations. Finally, the global topology map was obtained after establishing the reachability relationships between nodes. The simulation experiment results showed that the topological maps generated by STGA had obvious advantages in the richness of topological relationships. Besides, the topological maps also showed certain advantages compared to grid maps for the planning efficiency and security of global paths. Furthermore, the rich topological nodes on the global topological map were feasible in solving path conflicts of multiple robots. Note to Practitioners—Multi-robot system has better efficiency and system robustness, but how to solve the path conflicts among robots is a problem. We propose a method to solve multi-robot conflicts with global topological maps. This topological map is constructed by STGA. The grid map environment is discretized into a set of topological nodes, which have been used to maintain the spatial transitions of each robot in the environment. When robots encounter unavoidable path conflicts, they are scheduled with the help of topological nodes to achieve orderly and efficient collaboration.

HIGHER EDUCATION-CHOICE OF INTERNATIONAL STUDENTS AND ITS INTERACTION WITH UNIVERSITY SERVICES : Developing a guideline for universities by using the case of Sweden and Malardalen University


In order to obtain evidence of the security and privacy issues of products, services or an organization, systematic approaches to measuring security are needed. In this study we survey the emerging security metrics approaches from the academic, governmental and industrial perspectives. We aim to bridge the gaps between business management, information security management and ICT product security practices. If appropriate security metrics can be to offer a quantitative and objective basis for security assurance, it would be easier to make business and engineering decisions concerning information security. We believe that being able to express a high-level taxonomy of security metrics will help the actual process of developing feasible composite metrics even for complex situations. A welldefined taxonomy can be used to enhance the composition of feasible security metrics all the way from business management to the lowest level of technical detail. Information security management, business management and, on the other hand, software security and network security engineering have been handled as separate areas. Common metrics approaches can be used to bridge the gaps in between.


Emulsion polymerization is a polymerization process with different applications on the industrial and academic scale. It involves application of emulsifier to emulsify hydrophobic polymers through aqueous phase by amphipathic emulsifier, then generation of free radicals with either a water or oil soluble initiators. It characterized by reduction of bimolecular termination of free radicals due to segregation of free radicals among the discrete monomer-swollen polymer particles. The latex particles size ranged from 10 nm to 1000 nm in a diameter and are generally spherical. A typical of particle consist of 1–10,000 macromolecules, where macromolecule contains about 100–106 monomer units.


It is disclosed a device for transmitting shift movements in a motor vehicle manual gearbox, which (10) has a shift rail and disposed on the shift rail selector fork (12). The latter has a basic body (14) and possibly an output connected to the base carrier (16) for supporting the shift fork to the shift rail. According to the invention, the base body with the shift rail or the carrier is form-fitting and, if necessary, non-positively to a majority proportion of the forces and moments on the shift fork in the operation of the motor vehicle gearbox transmitting composite (18) is composed, which at least in the region of the connecting points (20) of base body, shift rail or carrier with a plastic (22) is molded, in order to fix the basic body, shift rail or carrier permanently in their positive and possibly frictional connection. As a result, a compact apparatus is provided which is capable of the forces and moments on the shift fork in operation without the risk of excessive deformations to be reliably transmitted, and is also easy and economical to manufacture.


One of the key problems confronting researchers in the field of microrobotics is designing and implementing reliable controllers for insect-scale micro air vehicles (FWMAVs), which are tiny flying robots typically inspired by insects. In fact, although these insect-size robots could have numerous useful applications, for instance, assisting humans in search and rescue missions or in agriculture, developing controllers that match their size and structure has so far proved to be difficult.


An in vivo clinical program investigated the relationship among oral microorganisms, bacterial plaque, and calculus formation. Benzethonium chloride, cetylpyridinium chloride, and Vancomycin provided a moderate reduction in bacterial plaque accumulation (30 to 35%). Hexachlorophene was relatively ineffective. One antibiotic, CC 10232, consistently furnished substantial reductions in plaque formation (70 to 77%) and calculus formation (75%). Only Vancomycin significantly reduced the gram-positive population. None of the antimicrobial agents caused changes in the staphylococcal or yeast populations.


In 2019 the University of Auckland (UoA) introduced compulsory capstone courses for all undergraduates in the Faculty of Science in recognition that students required more support to transition from being a student of a discipline to a practitioner. One requirement of the science capstone courses was to provide a vehicle for students to demonstrate the attributes of the graduate profile. Many universities have established graduate profiles to provide clarity to students, staff, and employers alike about the qualities graduates from their institution should possess. This research sought to establish whether UoA graduate profile attributes could be demonstrated and assessed in a statistics capstone course. A framework to evaluate the demonstration of graduate attributes was developed, which along with some preliminary results is presented and discussed.


Surveys are a vital tool in understanding public opinion and knowledge, but self-reported behavior in surveys generally leads to inaccurate estimations. We explore a popular and important behavior frequently estimated with surveys: news consumption. Previous studies have shown that television news consumption is consistently over-reported in surveys relative to passively collected behavioral data. We show that the bias also exists in estimates of online and social media–based news consumption, and in estimates of trends. Further, we show that behavioral data can address a wider range of research questions. Although behavioral data are not perfect ground-truth, they are more accurate and useful than survey data in this capacity. We outline a framework for using a mix of behavioral and survey-generated attitudinal data to accurately estimate consumption of news and related effects on public opinion and knowledge, conditional on actual media consumption.


This anatomic study suggests that an understanding of the thickness of the atrial septum should allow better visualization of most portions of the blade‐shaped atrial septum during cross‐sectional echocardiography, both in normal subjects and in patients with ostium secundum atrial septal defects. The thickness measurements also demonstrate that difficulties in imaging the atrial septum are a function of resolution limits of existing echocardiographic equipment.


Abstract A celebrated theorem of Shoda states that over any field (of characteristic ), every matrix with trace can be expressed as a commutator , or, equivalently, that the set of values of the polynomial on contains all matrices with trace . We generalize Shoda's theorem by showing that every non-zero multilinear polynomial of degree at most , with coefficients in , has this property. We further conjecture that this holds for every non-zero multilinear polynomial with coefficients in of degree , provided that .


The case of Germany is taken as an example of cyclical variation in higher education enrolment in the sciences. The article argues that the mechanism underpinning these fluctuations is the cobweb model. This model establishes a recursive loop between trends in enrolments in a discipline and trends in the labour market associated with this discipline. The analysis highlights two conditions that are required for the model to apply: the elasticity of higher education capacity and the segmentation of the labour market.


Many people attribute the invention of the printing press (with moveable metal type) to Johannes Gutenberg, a German, in the 1450s. The 42-line Gutenberg Bible bears his name in recognition of this feat. Was Gutenberg, however, really the first?
