Objective
Find abnormal changes of plasma lipid metabolism-related proteins before 20 weeks of gestation in patients with hypertensive disorder of pregnancy(HDP), and preliminarily investigate the role of plasma apolipoprotein C4 elevation in HDP.

Methods
A nested case-control study was used. The plasma were collected from pregnant women who underwent routine prenatal examination in Guangzhou Women and Children′s Medical Center from November 2014 to March 2017. Label-free mass spectrometry was used to detect the differences in plasma lipid metabolism-related proteins before 20 weeks of gestation between 12 pairs of HDP patients and normal controls, and different 48 pairs of samples were used for verification. The protein with the most significant difference multiples was screened to study its effects on monolayer permeability and nitric oxide secretion of endothelial cells. One-way ANOVA was used for comparison between groups, and P<0.05 was considered as statistically significant difference.

Results
Compared with the control, the lipid metabolism-related proteins, APOC4, Fatty acid-binding protein 4 (FABP4), Apolipoprotein E (APOE), Apolipoprotein C3 (APOC3) and Beta-2-glycoprotein 1(APOH) raised to 1.94, 1.82, 1.59, 1.55 and 1.38 times, phospholipid transfer protein (PLTP) decreased to 0.78 times in plasma before 20 weeks of pregnancy of patients with HDP (t value were 2.499, 2.497, 2.081, 2.098, 2.426 and 2.564, respectively, P<0.05). Cell experiments results showed that 50 ng/ml APOC4 significantly increased 20% HUVEC single layer cell permeability to FITC-labeled dextran (F=455.4, P<0.01), and significantly decreased the level of nitric oxide in the supernatant of HUVEC culture by 25% (F=61.92, P<0.01).

Conclusions
Before diagnosis, plasma protein levels involved in lipid metabolism in HDP patients have been changed, resulting in abnormal lipid metabolism. APOC4 can increase the permeability of vascular endothelial cells, inhibit endothelial source of NO secretion, cause endothelial dysfunction.

1. The question of quantum representation A fine-grained quantum state of the world is a questionable concept insofar as its details are not empirically verifiable. Since, however, setting any fixed boundary to the applicability of quantum description suffers from arbitrariness, and since some aspects of a supposed quantum state of the world may be partially testable, after a suitable clarification of the sense in which probability is being used in that context, it is perhaps not entirely absurd to consider the existence of a coarse-grained quantum state of the world. The quantum state, complemented by dynamical laws and other ingredients, is then supposed to provide a description of the world as a closed system – a system that contains also the observers and does not need to refer to anything external. Since the consistent-histories formulation of quantum mechanics 1,2,3 has been advocated by some of its proponents as a natural framework for dealing with closed systems, this language will be used as a basis. In this framework events are represented by projections. A family of consistent histories is specified by an initial state ρ(0), the Hamiltonian of the world H, and sequences of events. Each sequence is represented by a chain of Heisenberg-picture projectors:

The disruption era that initiated the 4.0 revolution has caused some types of jobs and professions in Indonesia disappear, replaced by machines/applications with artificial intelligence technology. These conditions force universities to change the orientation of producing ready-to-work human resources, to produce human resources ready to create jobs for themselves and others. Therefore, the urgent change is on the curriculum and its implementation through learning strategies. This paper is a development of entrepreneurship learning concept in university with system approach. The study used is explanatory, with the aim of inspiring the role of university management to provide a conducive academic atmosphere to develop the entrepreneurial spirit of students and lecturers. Entrepreneurship courses are made into compulsory subjects with learning achievements relevant to the profile of graduates in each course.

There are some studies that explored the effect of social media on marketing and consumer buying behavior and there is still a need to further understand this effect. However, this study aims to explore the use of social media sites and the effect of social media on the buying decision of the commercial banks' consumers in Jordan. The sample of this study conducted with 200 consumers to understand how consumers use social media and how it affects their buying behavior of different banking products and services. The findings show that social media affect consumer buying behavior by 69%. Also, consumers mostly used Facebook and it mostly affecting consumer buying behavior by 73% and the most influential factor that affects the relationship between social media and consumer buying behavior is interactivity by 63%. The implication of these findings suggests that commercial banks in Jordan should focus on their marketing strategy and they have the opportunities to seize the power of influence of social media.


In this article we explore forms of presence and absence in the framings and perception of the spectator based on scenes and frames from the film The Eclipse (1962) by Michelangelo Antonioni. We find in the director's intention in realizing this film what we call the "eclipse of visuality," that is, traces between the visible and the invisible in the montage of the cinematographic planes. The intrinsic time of the montage causes the frames to return in another manner, relate to other frames and above all, to leave traces in the landscape of images and sounds in movement. In this discussion about traces of the invisible and the memory of the visible, we deepen the specular concepts of traces and aura in Benjamin and contrast them with the concepts of time and memory in Bergson.


High‐pressure forming of metal sheets is an innovative forming technology for the production of complex components and offers high potentials to improve the properties and qualities of sheet metal parts. This report describes investigations of a newly developed active‐elastic tool system referred to as ACTEC system. Unlike the use of a comparable semi‐rigid tool system, the ACTEC system shows improvements with respect to the material flow in the flange area and reduced sheet thinning in critical corner regions of the workpiece. In addition, the clamping forces respectively sealing forces necessary to avoid leakage in the tool system during the forming process can be reduced. Moreover, the specific design of the ACTEC‐system as well as current experimental examinations are presented and discussed.


TO THE EDITOR: The recent paper by Wall et al.19 (Wall SA, Thomas GPL, Johnson D, et al: The preoperative incidence of raised intracranial pressure in nonsyndromic sagittal craniosynostosis is underestimated in the literature. J Neurosurg Pediatr 14:674–681, December 2014) on intracranial pressure (ICP) in a selected group of untreated children (mean age around 5 years) with sagittal synostosis ends with the recommendation that intraparenchymal ICP monitoring "should be considered and used routinely in all patients for whom a nonoperative course of management is proposed, no matter the nature or severity of the calvarial deformity." As this represents a radical departure from the clinical practice of many, if not most, craniofacial units and because we fear the recommendation could lead to an epidemic of invasive monitoring (with its small but never absent risk of brain injury), we suggest that the following factors be considered. Most importantly, their recommendation is associated with no identified benefit to the patients in their study. Not only do they state that "developmental delay was not significantly more common in patients with elevated ICP," but they also reveal that "patients who manifested symptoms suggestive of raised ICP but who were found to have normal ICP on monitoring experienced an improvement or resolution of their symptoms over time." There is no mention of what happened to those who did have abnormal ICP. In fact, the only support for their recommendation is their statement, "It remains reasonable to assume that continued chronically raised ICP in [sagittal craniosynostosis (SC)] is liable to curtail an individual's neurocognitive development, even if it does not reliably cause a marked developmental delay and is not responsible for many of the developmental abnormalities seen in SC." But is such an assumption in the absence of any supporting evidence "reasonable" enough to bear responsibility for one, possibly two, surgical interventions—one of which is a major cranial procedure? Then there is the problem of what childhood ICP should be considered abnormal. The "true" level of childhood ICP remains, for obvious reasons, unknown. As Dominique Renier and his colleagues wrote in their classic 1982 paper,13 "The definition of 'normal' and 'abnormal' ICP recordings in children raises an initial problem." Although the "Paris" range13 (< 10 mm Hg normal, 11–15 mm Hg borderline, and > 15 mm Hg raised) used here is most frequently accepted in craniofacial circles, a close reading of the 3 references5,9,17 used to support those values suggests the upper limit of their range could just as reasonably have been raised to 20 mm Hg. Indeed, in a previous paper8 from Wall and colleagues' unit (similar in its message but dealing with unicoronal synostosis), the authors state that "intracranial pressure was defined as elevated if the mean pressure was greater than or equal to 20 mm Hg." It would be interesting to know their reasons for a change which, as they state in their Discussion, would reduce the number with raised ICP in their 39 monitored patients from 17 (44%) to 6 (15%)—and that's without the 6 who were not monitored at all but were "well and asymptomatic when last reviewed." Their inclusion of "more than 3 B-type waves in a 24hour period during sleep" as part of their classification of abnormal ICP is not helpful in the absence of any accompanying definition. "B" waves have had a checkered history since Lundberg first identified them in a study dealing predominantly with intracranial tumors in adults. Eide et al. pointed out7 (in a paper referenced by Wall et al.) that "the identification of B waves is subjective" and for that reason did not consider them useful in the diagnosis of raised ICP. In Renier et al.'s 1982 study,13 waves superimposed on a non-elevated baseline ICP (their "third type") were dismissed as normal. In Wall et al.'s study,19 all 6 patients with 3 or more B-waves had baseline pressures of or below 15 mm Hg. Nevertheless, their presence was judged sufficiently abnormal to justify calvarial remodeling (surgical details not given despite some techniques producing a temporary rise in ICP). The waves of increased ICP superimposed on an elevated baseline observed in children with syndromic/complex forms of craniosynostosis occur particularly during REM sleep–associated episodes of airway compromise. Although children with single suture synostosis are unlikely to be so affected, it does raise the question of what effect a "normal" degree of childhood adenotonsillar hypertrophy may have on ICP. To take an extreme example, it could be argued that any child (with or without craniosynostosis) who snores at night runs an ICP that, according to the criteria quoted in the authors' study, would qualify them for cranial vault surgery. On a lighter note, the authors' observation that raised ICP was seen less frequently in children with obvious scaphocephaly than in those in whom it was minimal or absent altogether might reflect no more than a tendency for the former to sleep more comfortably on their sides than their backs (when a vulnerable airway may be compromised).

The 2008 Guidelines for Physical Activity for Americans and the National Physical Activity Plan are recently available tools for use by practitioners and scholars in developing and evaluating programs and interventions to increase physical activity across all populations. With the lowest rates of health-benefiting physical activity according to national statistics, targeted communities are often low-income and ethnic minority populations experiencing a chronic disease burden. The aims of this paper are to raise issues about the need for greater sociocultural critique of evidence-basis and other scientific parameters, to comment on the need for the inclusion of sociocultural analysis in physical activity assessment and intervention, and to raise some issues related to the need for kinesiology to deepen its relationship to the physical activity public health sector.


The use of information and communication technologies is increasing in the present scenario to a great extent for various purposes such as education, entertainment, business, e-governance, and so on. When ICT use expanded its origin, it has also predominantly taken a huge place in domestic activities. In the recent decade, the domestication of technologies in home has been expanding and its influence in family activities and family members must be a considerable area to study. Though many scholars from various countries attempted to understand the ICT influence in family life, this chapter adds a contribution to the field by analysing how the different activities in domestic life influences the family dynamics. This research collected the data from two different generation family members such as parents and children. This will help to understand how the ICT use influences the intergeneration family members. It is found that ICT has a desirable influence in family activities. Young adults are highly influenced by parents, and the regular monitoring is expected to avoid harmful effects.


The different combinations of genes active in different cells control the development and diversity of multicel-lular organisms. Yet the codes that control this process, written in both cis–regulatory and protein–coding DNA sequence, are poorly understood. This is despite the availability of imaging techniques that allow detection of gene activity at the resolution of single transcription units on chromosomes in individual interphase diploid nuclei[1]. While it has been shown that digital cell atlases are indeed possible[2], producing query-able models from imaging for Systems Biology[3] is far from commonplace for even the simplest of organisms. While much algorithmic work has been done on transforming pixels to meaningful objects (i.e. segmenting cell nuclei)[4], this necessary first step is far from a solved problem. Algorithm tuning remains a critical component and requires expertise in computer vision and image processing. This expertise is called upon repeatedly with new experimental data: when changes in the model organism, hybridization method, or the microscope result in changes to the generated images. We have successfully developed adaptive segmentation methods[5] that, while tuned for particular types of images, are tuned using machine learning methods. The advantage machine learning provides is rather than have the experimentalist tune the computer vision parameter(s) directly—this, again, requires an understanding of computer vision—the experimentalist instead tunes the system by providing direct feedback. The feedback mechanism is designed to be a of a natural form: given a collection of segmented pixels, the experimen-talist labels each collection as " a partial nucleus " , " a combination of two nuclei " , " a complete nucleus " , etc. From these these labeled collections we build classifiers that mimic the experimentalist's recognition of various segments. Using the human labeled examples as input, classifiers are built using JBoost[6], an open source, Java implementation of the Adaboost machine learning algorithm[7]. Adaboost generates a mapping from segments to scores, where high scores correspond to high confidence that the segment is correct (Figure 1a–g). Adaboost is a general-purpose learning algorithm which is particularly powerful when combining many weakly predictive features. The predictive features in this case are the values of the morphological features of the segments (Figure 1f). JBoost generates classifiers in a form of decision tree called Alternating Decision Trees (ADT)[8]. The ADT classifier (Figure 1g) acts a as proxy for the experimentalist, and we use these classifiers to guide the search for proper segmentations. As the experimental conditions change …

Background: Despite advances in surgery, radiotherapy and chemotherapy over the past three decades, no significant improvement in the prognosis for oral cancer has been observed. This could change if the cancer can be detected at an early stage. Aim: To evaluate the p53 and PCNA (Proliferative cell nuclear antigen) expression as an indicator for clinical aggressiveness in dysplasia and squamous cell carcinoma (SCC) in oropharyngolaryngeal (OPL) region. Materials and Methods: 50 histopathologically diagnosed patients were taken from the oral pathology department of our institute. It comprised of 15 dysplasia cases and 35 SCC cases of OPL region. Immunohistochemistry was done to investigate the expression of p53 and PCNA and scored based on percentage of positive tumor cells and the staining intensity. Results: The expression of p53 and PCNA was detected in 34(68%) and 50(100%) cases respectively. There was significant increase in staining intensity and percentage of tumor cells expressing p53 and PCNA from dysplasia to different grades of SCC. Conclusion: Present study concluded that p53 and PCNA expression can be used to assess the potential for malignant transformation in dysplasia and aggressiveness in different grades of SCC of OPL region.


The role of global geometry in data analysis is examined in a special case. If Y is a topological space, n > 1 is the sample size, and X = Y" is the sample space, a measure of location for Y is a map A:XY which is symmetric in its arguments and for any y E Y takes (y,...,y)EX to y. It is known that for 'most' spaces Y no continuous measure of location exists. In particular, if Y is a sphere (e.g. if the data is directional) there is no continuous A. In this case we can weaken the hypotheses by requiring, in addition to symmetry, only that every yE Y be within r/2 radians of Myy, ..., y). Then A must have a singularity, x EX, so bad that no neighborhood of x is mapped by A into any open hemisphere. (A 'singularity' of A is a data set at which A has no limit.) An analogous result holds for 'axial data'.


This article empirically examines the results of the 2020 Democratic Party's presidential nomination contests in the five states that adopted ranked choice voting rules. The findings shed light on how voters ranked candidates based on not only the need to nominate the strongest candidate to represent the party in the general election, but also to ensure representation of the diverse electorate at the national convention. The paper also considers how the 15 percent threshold of vote shares required to earn national delegates affected the results of RCV elections in 2020. Finally, it assesses the possibility of changes to the delegate allocation if this threshold is altered in the context of RCV rule adoptions in the future.

An architecture implemented for intermixed planning and execution of an observation mission for an UAV is described. The mission and its constraints are reported. The ProCoSA tool used to specify the UAV desired behaviour through Petri nets is presented. A planning sub-system optimises the 2D itinerary and the 3D associated trajectories while a guidance sub-system computes the controls sent to the modelled UAV. First simulation tests highlight the feasibility of the structure and the reactive capabilities of intermixed planning and execution architecture in nominal and degraded situation.

This MSc thesis presents the adaptive strategies for supply chain management. The objective is to build mechanisms and methods for a trading agent performing the role of personal computers manufacturer. Trading Agent Competition for Supply Chain Management (TACSCM) is an environment where the agent competes with other participants for procuring components and selling products. For the purpose the thesis the MasterBham agent was developed and joined TAC-SCM in 2007. This environment provides a benchmark as well as determines the agent architecture. This distinguishes the supply model and demand model in the agent architecture. Developed strategies aim to maximize the agent efficiency on the market by providing the mechanism for maximizing the profits. Component Procurement Problem was modeled with Multiple-Choice Knapsack Problem and solved with Genetic Algorithm. Feedback mechanism was proposed as the link between supply and demand model.

Pseudogenes are dysfunctional DNA sequences that share sequence similarities with functional genes. Accurate identification of pseudogenes is important to understand biological and evolutionary histories of genomes and genes. Most existing pseudogene identification tools rely on homology search between genomic sequences and annotated proteins of the same genome. However, when accurate annotations of the genome of interest are not available, these tools will not be able to provide reliable pseudogene identification. In this work, we introduce a new pseudogene identification tool named PseudoDomain, which is designed to accurately identify processed pseudogenes in genomes with or without gene annotations. PseudoDomain uses profile Hidden Markov Model-based homology search between genomic sequences and protein domain families, which are conserved in a large number of proteins. Experimental results show that our method is able to effectively identify processed pseudogenes with high sensitivity and low false positive rate. In addition, it can accurately predict the number and positions of frameshifts within putative pseudogenes. The source codes of PseudoDomain are available at http://sourceforge.net/projects/pseudodomain/.


How does one measure the productivity of an individual participating in a team sport? The purpose of this inquiry is to answer this question via an econometric model that links the player's statistics in the National Basketball Association (NBA) to team wins. This model will then be employed in the measurement of each player's marginal product. Such a measurement is useful in answering the question offered in the title, or a broader list of questions posed by both industry insiders and other interested observers.

The retinal thickness analyzer (RTA) is an ophthalmic imaging instrument for the measurement and mapping of the thickness of the retina. The RTA is based on the principle of optical triangulation. A laser beam, which is offset from the optical axis of the eye, is projected onto the retina so that it hits the retina at an angle relative to the optical axis. The light reflected back from this beam at the retina is imaged onto a CCD camera through an off-axis aperture opposite the offset of the incident beam. This cause the light reflected from different layers of the retina to be offset in the image. The size of the offset of light from a retina layer is a measure of the depth of the layer in the retina. Image processing algorithms, which is used to analyze the image for determination of the retinal thickness and structure. A curve fitting procedure based on a physical model of retinal light scattering is used. Thickness determination repeatability is 13 microns (1 sigma). For the registration of thickness measurements, conventional images of the retina are acquired in coincidence with the thickness measurements. Feature extraction algorithms are used to register these images relative to each other and to locate the thickness data on the retina.


The aim of my research is to reveal the predictive relationship among adolescents' social media usage, loneliness and life satisfaction. Relational scanning model, which is a sub-type of general scanning model, is used in the study. The study group of the research is selected, through the appropriate sampling method, from the adolescents who study at different grades and in two different Anatolian Highvschools in Basiskele district of Kocaeli in the 2017-2018 academic year. The study group consists of 348 female and 252 male students. 600students participated in the study. In this study "Life Satisfaction Scale", "Ucla Loneliness Inventory" and "Social Media Attitude Scale" are used as data collecting device.  Structural Equation Modeling Analysis is conducted in the study. In addition, percentage and frequency calculations of the collected data are implemented through "SPSS18"packed programme. When the predictive relationships between adolescents loneliness levels and social media usage are examined, it is indicated that there is a positive directional relationship. When the predictive relationships of adolescents between the level of loneliness and life satisfaction are examined, it is indicated that there is a negative directional relationship.

In order to analysis the relationship between the Gross National Product and the variables of the industrial economy. Based on the related data of China's GNP and Industrial Economy from 1978-2014, the relationship of between China's GNP and the variables of the industrial economy was analyzed by adopting the methods of econometric analysis of co-integration test, error correction model and Granger causality test method. The result showed that: 1) The Industrial Economy variables have positive on GNP except the primary industry; 2) When the short-term volatility deviated from the long-term equilibrium, the system would adjust the non-equilibrium state with intensity of 0.1050 back to the equilibrium. 3) Under the Granger causality, the GNP and primary industry, the secondary industry, the tertiary industry growth showed the individual Granger causality relationship. Finally, some advice was proposed to promote the GNP and to coordinate the growth of variables industrial economy together.


The paper considers in detail a calculation of a multispan continuous beam using two methods: work method and method of three-moment equations. As a result of comparison and detailed analysis of these methods it has been exhibited that the calculation using three-moment equations is non effective and awkward method. It is known that the method for calculation of continuous beam using three-moment equations is only artificial transformation of work method. Thus while calculating any statically indeterminate systems including continuous beams it is more expedient to apply a common calculative method, that is a work method.


Thin films of VO2 were synthesised by atmospheric pressure chemical vapour deposition (APCVD). The effect of deposition time on the thickness of the films was studied. The samples synthesised were the first time monoclinic VO2 has been demonstrated by the reaction between vanadium (IV) chloride and ethyl acetate under APCVD conditions. Multi-layer films of VO2/SiO2/TiO2 were also synthesised by APCVD and the effect on the thermochromism and visible light transmission were investigated. The multi-layered VO2/SiO2/TiO2 is the first such multi-layer to be demonstrated by APCVD. A specialised Fluidised Bed Chemical Vapour Deposition (FBCVD) reactor was designed and built specifically for the project, with this design being utilised to coat powder substrates with thin films of TiO2. A multi-shelled system of anatase on rutile on mica was deposited to demonstrate that the FBCVD system is capable of depositing core-shell and multi-shelled systems with fast and uniform growth rates. The different TiO2 samples were tested for their photocatalytic properties by measuring stearic acid destruction rates. VO2 nanoparticles were synthesised by Continuous Hydrothermal Flow Synthesis (CHFS), with the effect of temperature and residence time within the CHFS reactor on the phase produced and particle size distribution was evaluated. This is the first time that CHFS has been used to produce VO2 nanoparticles. Finally, CHFS was used to synthesise nanoparticles of Nb doped VO2. The effect of varying the concentration of Nb was investigated by evaluating the phase of vanadium oxide synthesised, the range of particle size and the thermochromic properties observed in the material.


Basic concepts of bedside ultrasound have been discussed in two previous articles. The focus of this article is the evaluation of the renal system with bedside ultrasound.


600 mg/d. We noticed an improvement after only a few days and within a month the camptocormia had disappeared. Treatment with biperiden and lorazepam was discontinued progressively. The improvement is not only reported in the camptocormia but also in his psychotic symptoms and aggressiveness; he is able to work, and his involvement in sports and the quality of his social life also increased. In the intervening 12 months of follow-up appointments, the patient's condition continues to improve.


Wireless communication technologies became the key integral part of modern systems, experiencing an explosive development during the last two decades and penetrating to enormous number of application areas, based especially on the concept of cellular phones. More recently, short-distance wireless communication has also been discussed as a way to connect embedded electronic systems in industrial applications, including. industrial robots and other real-time and safety-critical systems. As approaching into new areas, all such dependable systems, and in combination with advanced test- and error-correction technologies, have to meet new challenges. Existing technologies for error correction are either not capable of managing multiple faults, or they are too slow in terms of encoding and decoding to satisfy industrial timing constraints. The paper introduces a new concept of error detection and- correction as well as baseband path testing, which promises a combination of reasonable overhead and relatively fast encoding and decoding.


It is customary to derive the quantum‐mechanical theory of quasifree particles by means of Green‐function techniques, making use of the Green function of a free particle. It is pointed out here that similar techniques can be used in atomic and molecular calculations if use is made of the Green function of the hydrogen atom, rather than the Green function of a free particle. The Green function of the hydrogen atom is derived by means of contour integrations in the complex plane, following previous work by Meixner. We also derive a slightly modified Green function which is adapted to perturbation calculations of the ground state. Both of these Green functions are obtained as expansions in terms of spherical harmonics; the radial functions are expressed in terms of confluent hypergeometric functions.


Wonder is the first passion in all inquiry and our reason to know, yet a phenomenon that is largely neglected in organizational research. Taking a relational and process approach, we develop a theory for the role of wonder in organizational inquiry. We propose that wonder in inquiry unfolds as a twofold movement between receptive appreciation and self-transcendent search, and we chart wonder's course in four stages or "moments" of arousal, expansion, immersion, and explanation. Examples from generative experiences in qualitative research, hydrocarbon exploration, and feature journalism are used to illustrate and qualify this theory. At last, we emphasize main implications for organization studies in the importance of wondering together, of upholding the mysteries of wonder, and of keeping wonder alive in our conversations.


Obesity and overweight have become a global problem affecting not only high income countries but also developing countries. According to the World Health Organization (WHO) more than 1 billion adults are overweight and at least 300 million of them are obese. Experimental and clinical studies indicate that there is a relationship between iron metabolism and weight status. Iron deficiency is significantly more prevalent among obese individuals compared to non-obese ones. Adipose tissue produces many pro-inflammatory cytokines (interleukin-1, interleukin-6, tumor necrosis factor-α) and adipokines (leptin, adiponectin, resistin) that influence iron homeostasis. According to recent studies, hepcidin, the main regulator of iron metabolism, can also be synthesized by the adipocytes. Development of iron deficiency among obese and overweight children has potentially harmful effects, which can lead to behavioral and learning problems as well as lowered resistance to infections. For this reason, screening for iron status among children with elevated BMI should be recommended.


With the advent of web 4.0 and development of intelligent agents' application in this context, electronic commerce faces new capabilities and requirements. One of these requirements is the design of protocol and appropriate negotiation strategies. In the real world, negotiation is conducted with incomplete information about opponent, and achievements of participants depend on their ability to reveal information in such a way that facilitates reaching an agreement without risk of losing personal profit. In this paper, a buyer agent is designed, which has auto negotiation ability with opponent and obtains information on opponent in terms of a strategy by using a machine learning method. Knowing the opponent's strategy allows the agent to increase its profit. By using Bayesian learning, this agent learns opponent's strategy during negotiation. Experimental results show that Bayesian learning method increases the efficiency of negotiation which is measured and evaluated with parameters such as average buyer utility and average seller utility. Average buyer utility and average seller utility have increased from 90% to 94% and 27% to 31% respectively.


In this paper we describe a study exploring why users spend more time in email than originally intended, which we call getting lost in email. To study this phenomenon, we implemented an IMAP logger that also dispatched diary entries to collect data for twenty participants over a two week period. Most participants reported getting lost in email during both short and long sessions. Our analysis suggests two primary factors in getting lost: the number of emails awaiting a reply and whether or not the session caused an interruption. We conclude that much of the problem around getting lost in email is in managing the tension between promptly responding to messages while limiting engagement with email.


Experimental studies were carried out to assess the mixing performance of cavities in supersonic flows The co-flowing supersonic streams are of Mach numbers 1.6 and 1.2 issuing out from co-axial rectangular nozzles into a rectangular mixing duct which has wall mounted cavities. Nine cavities of different length to depth ratio (L/D) varying from 0.43 to 3.08 were tested in two configurations. Characterisation of the cavities was done by measuring the acoustic pressure oscillations produced by the cavities. Most of the cavities tested were found to be augmenting mixing to a less or more extent when the momentum flux at any cross section was compared. The mixing enhancement was more distinctively noticeable in the thermal mixing of non-isothermal streams. The shear layers, Mach waves and compression and expansion waves were clearly observed in the schlieren pictures. The planar Mie scattering visualisation gave qualitative indication of the mixing enhancement provided by the cavities. The maximum total pressure loss due to cavities on the wall of the mixing duct was found to be within tolerable limits.


In this paper, an optimization method for arranging a four-coil wireless power transfer (WPT) system is proposed to improve medium or long-distance power transfer efficiency. The system efficiency model with respect to the coil mutual inductance is established. Then the nonlinear constraints about power and distance are given, and the distance between adjacent coils is investigated with the optimal design. The system efficiency with identical coils and different coils is also compared based on the optimization. Finally, the simulation is carried out to show that the system efficiency can be improved from 56.42% under identical-coil-condition to 67.23% under different-coil conditions, where the distance between adjacent coils is optimized.


Expanded school-choice policies have weakened the traditional link between residence and school assignment. These policies have created new school options and new labor for families to manage and divide. Drawing on interviews with 90 mothers and 12 fathers of elementary-age children, I demonstrate that mothers across class, racial, and ethnic backgrounds absorb the labor of school decision-making. Working-class mothers emphasize self-sacrifice and search for schools that will keep their children safe. Middle-class mothers intensively research school information and seek niche school environments. Working-class and middle-class black and Latinx mothers engage in ongoing labor to monitor the racial climate within schools and to protect their children from experiences of marginalization. Partnered fathers and single primary-caregiver fathers invest less time and energy in the search for schools. These findings identify an important source of gender inequality stemming from modern educational policies and suggest new directions for research on school choice.


The Bcl-2 family proapoptotic protein, Bax, redistributes to the mitochondrion in response to varied stimuli, triggering loss of mitochondrial integrity and apoptosis. Suppression of MAPK kinase (MEK1) by the reagent UO126 in activated T cells main-tained in the cytokine IL-2 disrupts cytoplasmic localization of Bax and cell survival. UO126 triggers mitochondrial translocation of ectopically expressed Bax-GFP, and both UO126 and dominant negative MEK-1 (DN-MEK1) trigger increased apoptosis in Bax-GFP-expressing T cell lines. Because inhibition of PI3K or its target Akt also triggers mitochondrial translocation of Bax in T cells and apoptosis in Bax-transfected cell lines, we generated Bax deletion mutants to identify the region(s) that confers sensitivity to regulation by MEK1 and Akt. A deletion mutant (Bax 1–171 ) without the C terminus mitochondrial targeting sequence or an Akt target site (Ser 184 ) localizes to the cytoplasm and triggers low level apoptosis that is enhanced by DN-Akt or DN-MEK1. A construct that lacks the first 29 aa (Bax- (cid:1) 29) largely localizes to mitochondria, is highly apoptogenic, and is not inhibited by Akt or MEK1. Furthermore, Bax- (cid:1) 29 overcomes IL-2-dependent survival in a T cell line, whereas Bax triggers comparatively low levels of apoptosis in these cells. Cytoplasmic localization and regulation by MEK1 and Akt are restored in a mutant deleted of the first 13 aa (Bax- (cid:1) 13). Taken together, our results identify a region in the Bax N terminus that determines cellular localization regulated by MEK- and Akt-dependent signaling in T cells. The Journal or Bax-GFP, and after 15 h, the GFP-positive cells were scored for apoptotic nuclear damage, as described in Materials and Methods . The data are representative of four independent experiments. Inset , Expression of GFP or Bax-GFP in 2B4 ( lanes 1 and 2 , respectively) and Bax-GFP in Jurkat ( lane 3 ) using an Ab to GFP.

C , d11S cells were transfected with GFP or Bax-GFP, and after 18 h, the GFP-positive cells were scored for apoptotic nuclear damage, as described in Materials and Methods . The data are representative of five independent experiments. D , Lysates of 2B4, Jurkat, and d11S cells were assessed for the expression of the indicated proapoptotic proteins as indicated by Western blot analysis. p38MAPK was used to establish parity of loading.

Service robots want to achieve intelligent interaction, self-tracking is the foundation. At present, the tracking of indoor robots is mainly for human body tracking or object tracking with auxiliary markers, only one type of target can be tracked. In order to solve the above shortcomings, this paper designed an automatic omni-directional robot, using a common camera, according the different target using different strategies to achieve the tracking of any tracking, regardless of their status. The tracking strategy can be divided into two broad categories. One is tracking the human. Using based classifier face tracking and feature point tracking, Set the face tracking as a high priority of tracking, and the feature point tracking is added to ensure the tracking integrity when face blind spots appear. Another is the tracking of objects in any state. In this case, the feature points are used to track the target feature points, using Shi-Tomasi algorithm and Lucas-Kanade algorithm. The 2D coordinates of target sub-pixel level accuracy are obtained. Combined with laser range finder, build three-dimensional coordinate positioning. Finally, this paper verifies the feasibility of the system through experiments. The success rate of tracking is over 90%, which has high reliability.


The existing business process is evaluated by some quantitative metrics (such as time, cost, etc) in a process owner-focused way, which is neither compatible with the viewpoint of customer-focus in BPR, nor a reflection of relationship between business process corporate strategy. Based on the philosophy of balanced scorecard, considering the strategy influence and customer value improvement, this paper develops a balanced scorecard-based business process evaluation method, and presents the idea of the approximate linearization of metrics and the concept of Ideal Balanced State Deviation Degree. At last, a case study is performed. 


Among 143 women whose menarcheal age was documented during a longitudinal growth study, recall 39 years after the event gave the following results: menarche was recalled as 0.2 years earlier than the actual date (p<0.05), the standard deviation of recalled age was 0.3 years larger (p < 0.01), and the coefficient of correlation, r, between actual and recalled age was 0.60 ± s.e. 0.05. Accuracy of recalled age at menarche is of considerable clinical and scientific moment. There have been two reports to date of women whose ages at menarche were documented during the course of a longitudinal growth study, and who were queried some years thereafter. Livson and McNeill (1962) found, among 43 women questioned after 17 years, no differences in the means or variances of recalled and actual ages at menarche, which were correlated with an r of 0.75. Damon et al. (1969) obtained similar results for 60 women questioned some 19 years after menarche, with an r of 0.78. We report here the accuracy of recall for 143 white women whose menarcheal ages were documented during a growth study between 1922 and 1934, and who were queried, on the average, 39 years after menarche. Subjects and Methods In 1922, W. F. Dearborn of Harvard Graduate School of Education began a study of all children entering the first grade of three Boston suburbs.

Emergency battery lighting units (EBLs) in power plants provide lighting for personnel egress during loss of normal lighting as well as backup lighting for vital plant areas and equipment during a loss of power or other emergency situation. Failure of these units not only compromises personnel safety, but can also hamper safe plant shut down during an emergency. This guide provides concise, practical guidance relative to the use, application, and maintenance of emergency battery lighting units in power plants. It includes a description and evaluation of aging mechanisms, failure data, and life expectancy of typical EBLS, and focuses on root cause determination and preventive measures for limiting EBL failures. Appendices augment the guide by providing references, a glossary, and a discussion of relevant standards, codes, regulatory requirements and guidelines applicable to an EBL test and maintenance program. This guide can assist utilities in establishing maintenance programs that will provide a high level of lighting unit operability without excessive maintenance costs, and without compromising regulatory requirements.


Classification is a predictive modeling for a categorical target variable. Various classification ensemble methods, which predict with better accuracy by combining multiple classifiers, became a powerful machine learning and data mining paradigm. Well-known methodologies of classification ensemble are boosting, bagging and random forest. In this article, we assume that decision trees are used as classifiers in the ensemble. Further, we hypothesized that tree size affects classification accuracy. To study how the tree size in uences accuracy, we performed experiments using twenty-eight data sets. Then we compare the performances of ensemble algorithms; bagging, double-bagging, boosting and random forest, with different tree sizes in the experiment.

Technical University of Lodz Faculty of Organization and Management Department of Management Systems and Innovation ul. Piotrkowska 266, 90-924 Łodź, Poland E-mail: email@example.com Abstract The situation of many Polish textile producers is difficult. Lifting import quotas on textile products following Polish accession to the EU and the Schengen zone has resulted in a vast increase in the supply of apparel and textile products, mainly from Asian countries. According to the recommendation of the European Commission, one of the methods to remain competitive against low prices offered by China or India is to offer innovative products of considerably better quality. Unfortunately, it is estimated that only 25% of all textile enterprises innovate, most which occurring through imitation. While most Polish companies limit their expenses on R&D activities by adapting external ideas to local needs, some attempt to create competitive advantage has been made by introducing more advanced technologies. Nanotechnology is providing solutions that may help businesses gain technological advantage. This article presents financial aspects of the introduction of antibacterial and bacteriostatic fabrics.


Abstract On the Sacred Poetry of the Hebrews. Rereading Robert Lowth's Classic on Biblical Hermeneutics On the occasion of the 300th birthday of the Old Testament scholar Robert Lowth (1710-1783), this paper discusses sections of Lowth's Lectures on the sacred poetry of the Hebrews (Praelectiones de sacra poesi Hebraeorum, 1753) that are considered highly influential, especially in 18th-century Germany (Michaelis, Jerusalem, Mendelssohn, Herder et al.). It elucidates Lowth's theory of the origins and nature of poetry in general as well as his characterization of biblical poetry, in order to evaluate the hermeneutic legitimacy and relevance of his aesthetic approach to biblical exegesis. Contrary to the common objection from the perspective of secularization theory that the aestheticization of exegesis denotes its religious depletion, this paper argues that Lowth's project is to be understood as the attempt to use aesthetic means to render accessible the unique religious resonance of Old Testament poetry.


The quality-oriented education has promoted Chinese education and teaching reform. From non-utility view, the quality-oriented education of the university students focuses on cultivating the modern consciousness of university students. Among the modern consciousness, the consciousness of law is the fundamental symbol of the modern consciousness; the consciousness of green is the basic component;the consciousness of the globalization is the trend. As teaching staffs of universities, we should innovate the theory, activate our thinking and change our perspective. Only in this way, can we undertake the modern times' duty of education.


Public environmental awareness is extremely important on social environmental protection. In this study, through random sampling and relevant statistical analysis, Lin'an citizens were surveyed on their environmental awareness. As a result, education level and occupation type were screened out as two primary influencing factors. Based on this, three feasible measures were taken out. Meanwhile, this study is good to comprehensive understanding on nowadays small and mid-sized city residents' environmental awareness and could provide theory basis and scientific guidelines for future policy formulation and implementation.


A combination of a 32×32‐element silicon‐diode matrix and an Apple II computer is used to record and analyze Fabry–Perot interference ring patterns. The main advantage over conventional methods consists in the possibility of selecting the spectral resolution after registration and in the absence of alignment problems. Application of an image converter tube with VUV transmitting window in front of the matrix extends the applicability of the device to UV and VUV spectra.


cloud over counterintelligence disciplines there. At the core was the chief, James Angleton, and his trusted Soviet defector, Anatoliy Golitsyn; the trigger was the distrusted defection of another Soviet intelligence officer, Yuriy Nosenko. The saga was Homeric. It has been told many times-but never, I think, so well as in this meticulous logical and empirical exercise. The author has been one of CIA's finest intellects. He has published trenchantly in the open literature on theories of deception and counterdeception. Yet one must now acknowledge that cogent exoneration of Nosenko contributed to permanent rejection of Angleton, and eventually to years of reluctance to suspect even Aldrich Ames. So standards for vigilance remain disputable.

Abstract Pedagogic approaches to TVET offer a limited range of teaching strategies which make use of experimental learning. Thus experiments were developed for teachers of structural engineering and timber processing technologies and were subject to empirical evaluation by a researcher at the Otto-von-Guericke-University Magdeburg and Kassel University. This paper summarises the outcomes of the research and the empirical evaluation. The results of the study confirm that experimental training has a positive influence on learning achievement. In particular, it can be inferred that experimentally designed training is particularly supportive for the development of procedural knowledge.


In this research, a technique is developed to separate an additive fault from a multiplicative fault by using recursive update of predictor-based system identification. If additive fault occurs at the same moment of multiplicative fault in a system, the recursively updated system model can take away the effect of multiplicative fault from residual. Thus, purely additive fault affects on residual of which threshold is calculated based on Chi-squared distribution. In this research, the Chi-squared residual is computed as whitened-residual and its whitening covariance matrix is derived from residual itself in order to accommodate identification error. To detect multiplicative fault, the norm to measure the distance between the original system matrices and the changed is recursively checked with user-defined parameter. The benefit of this approach is illustrated with an adopted system.

Mexican art, dating back to 2500 BC, is enormously rich and stylistically varied, the product of the country's indigenous, 'mestizo' [mixed race] and Mexican cultures, which range from Olmec, Teotihuacan, Zapotec and Mixtec, to Mayan and Aztec. During the colonial period, the influence of European art was added, brought via Spain, and at the same time Catholicism prevailed over pre-Hispanic polytheism. Mexican culture as it is known today emerged at the end of the Spanish colonial period and its wealth is amply demonstrated in the content of the writings and other documents found in Mexican libraries today.


A preliminary investigations was carried out to study the antibacterial activity of the water soluble extracts of five and ten years old barks of Eugenia Jambolana Lam. (fam. Myrtaceae) on dysentery and diarrhoea forming micro organisms. It was observed that the barks of young plants have a better inhibitory effect on micro – organisms like Salmonella viballerup, Shigella dysenteriae 10, Shigella boydii 5, Sgigella dysenteriae 2.


Sperms adhere to oviduct isthmus for the presence of a heavily sialylated glycocalyx on the apical plasma membrane of isthmic epithelial cells, and form a sperm reservoir here. This kind of interaction between sperm and epithelial not only guarantees that there are appropriate number of spermatozoa at proper time arriving at the site of fertilization under proper condition and benifiting the viability of sperm in vivo and in vitro,but also modulates the velocity of capacitation. Hydrogen peroxide is the prime criminal of killing sperm in female reproductive tract, but mammalian oviduct can secrete catalase to survive the sperm in female reproductive tract. Studying on the effect of oviduct on the spermatoza is very important to making sure of modulation of fertilization, developing capacitation in vitro and healing some infertility theoretically and practically.


Conventional hierarchical organizations are inadequate in managing multi-dimensional artifacts such as publications. Much research has attempted at a more usable high dimensional information visualization and browsing experience, but has failed at the curse of dimensionality, exhibiting one or more of the following symptoms: (1) interface is unfamiliar, non-intuitive or cluttered; (2) dimensions viewable are limited or require to be in numeric domain; (3) update and/or browsing requires exponential time. This work proposes a hypercube artifact space model and an interactive browsing methodology, multi-dimension browse, which offers: (1) a familiar, intuitive and simple interface with summarization results; (2) browse against any and all dimensions; (3) update and browse costs linear in number of dimensions and artifacts respectively, and browse costs can be further reduced logarithmically on parallel platforms.

What unifies the accounts of history and progress presented by Adorno's Critical Theory and Metz's political theology? I show: (i) that both resist the 'magic spell' of an Enlightenment totality on whose strength the violent excesses of modernity have been built; (ii) that both accomplish this resistance by memory of victims or the 'losers of history'; and (iii) that both hold out hope for the possibility of progress in time. However, the two accounts differ in important ways. These differences stem from: (i) the transference of historical subjectivity from homo emancipator to the God of Jesus' passion; (ii) the role of the 'eschatological proviso' in guaranteeing theological futuricity; and (iii) the fullness of Metz's eschatological justice as compared to Adorno's conception of progress as the mere 'avoidance of catastrophe'. This project brings the work of one of the most influential social critics of the twentieth century into dialogue with that of a politically engaged theologian of the same historical-cultural context. In doing so, I hope to suggest the theological richness of Metz's approach but also the significant contributions of dialectical criticism to the practice of theology in the modern era.


In this article, we optimized the ohmic contact processing in InAlN/GaN high electron mobility transistors for the lower temperature of annealing by recessing of metalliza-tion to approach the 2DEG at the InAlN/GaN interface. The ohmic contacts which were recessed down to 5 nm depth and annealed at 700 °C 2 min. exhibited the contact resistance of 0,39 Ωmm while the channel sheet resistance was 210 Ω/square. These values are comparative to values of contacts processed at more conventional an-nealing conditions (800 °C, 2 min).

Moreover we applied the recessed ohmic contact technology to fabricate Schottky barrier (SB) HEMTs and MOSHEMTs with Al2O3 dielectric film. For MOSHEMTs, we measured the maximal reduction of the gate leakage current by about 6 orders of magnitude if compared with SB HEMTs. The maximal drain current of MOSHEMTs was about 750 mA/mm at VGS = 0 V and the maximal extrinsic transconductance (gme) reached 101 mS/mm. (© 2010 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim)


The technique of augmenting the repair of a torn anterior cruciate ligament (ACL) using the medial one-third of the patella ligament is well described. Questions concerning the viability of the augmentation tissue and the problems encountered with this method of repair are of importance in the evolution of a satisfactory, durable procedure. We report here a case of ACL repair with patella ligament augmentation. Subsequent problems with range of motion, methods of increasing the motion, and clinical observations of the augmentation at 10 months are discussed.


Objective To study the effect of postoperative irradiation of cancer of the rectum with stage Duke's B 2,C 1,C 2.Methods This paper analysed the treatment effect of 105 patients with stage Duke's B 2,C 1,C 2 treated in our hospital from January 1992 to March 1998.The patients were divided into two groups.Fifty five patients were treated by surgery alone and fifty patients by postoperative radiotherapy with cobalt in 1~2 months after operation at 50~55Gy/5~6 weeks.Results The five year survival rates of the 50 patients with stage B 2,C 1,C 2 were 81.8%,61.5%,38.7%,in the postoperative radiotherapy group and the 55 patients with stage B 2,C 1,C 2 were 60.0%,32.5%,11.7%,in the surgery alone group(P0.05) respectively.Five year recurrence rates of patients with stage B 2,C 1,C 2 were 33.3%,64.0%,66.7% in the surgery alone group and stage B 2,C 1,C 2 were 18.2%,17.4%,25.0%,in the postoperative radiotherapy group,respectively.Metastasis rates were 27.3%,10.0% in the surgery group and postoperative radiotherapy group respectively(P0.05).Conclusion Postoperative radiotherapy of rectal caner with stage B 2,C 1,C 2 decreases the recurrence rates and increase the long-term survival rates.


The threat of environmental degradation of the Martapura River as a result of an increase in built-up land has become a serious problem, so it is important to implement a new method using the integration of calculations of changes in built-up land and the sustainability of river area environmental management. This study aimed to cal - culate the change in built-up land directly integrated through Rap-RiverBuiltUp quantitative analysis on the envi - ronmental sustainability of the Martapura river area, Banjarmasin City. The research method used is the technique of spatial analysis of ETM/Landsat 8 OLI satellite landsat images and analysis of ecological, social and economic sustainability with Rap-RiverBuiltUP analysis. The results of the analysis of built-up land around the Martapura river, Banjarmasin City, have increased by 2.31% over the last 12 years, followed by a growth in population den - sity of ±1.5% annually. The implementation of sustainable environmental management needs to be prioritized with the efforts to periodically revise regional spatial planning regulations, especially the boundaries of built-up land to reduce the development of built-up land around the Martapura River. The sustainability status of the built-up area around the Martapura river is currently not sustainable. The ecological dimension indicates a less sustainable status, while the economic and social dimensions indicate a fairly sustainable status. Increasing the sustainability index value of the Martapura river from each dimension in the future is by making the lever factor an input for the management policy of the Martapura river, Banjarmasin City.


Charlie Chaplin made people laugh and he believed that "a day without laughter is a day wasted" for one who doesn't enjoy a good laugh with family and friends. Life gives us enough opportunities or reasons to laugh our heart out. Only we don't have enough time to embrace those chances. Due to stress, depression, lack of sleep, negative thoughts and feeling of isolation we aren't letting ourselves to smile at our own thoughts, leave alone laughing at something. Dr. Madan Kataria was the father of this Laughter therapy in India. He used this exercise to promote health through laughter around the world because he knew that laughter has some real health benefits. Laughter yoga is a unique style of yoga that involves laughing voluntarily. This new twist to the ancient practice of yoga is probably the only exercise routine that will leave you happier and healthier. It is an excellent cardio workout and what starts as a forced laughter becomes a real one and more contagious than a common cold. It combines yogic breathing and laughter exercise to make you healthy.


We present the results of a 10-day field experiment in which over 500 elite software developers were tasked with the challenge of developing a creative solution to a computational algorithmic problem from NASA. Participants were divided into two groups with identical skills distribution and exposed to the same competitive institutional setting. One group, however had self-selected and sorted itself into the competitive institution (as opposed to an outside option) and the other group was assigned to it. We find that the sorting effect, controlling for skills and formal incentives, nearly doubles the performance of the solutions developed as compared to the unsorted group. The sorting effect motivated more effort for individuals across the skills distribution and was of the same magnitude as the provision of formal incentives. Contrary to expectations of intrinsic crowding-out theory, high-powered incentives, independently motivated higher performance, especially at the higher skill levels.


Objective To observe the protective effect of edaraven on brain tissue and the therapeutic mechanism in rats following intracerebral hemorrhage(ICH).Methods In this series,96 Sprague-Dawley rats were divided into three groups at random(n=32 in each group):sham-operative group,ICH model group and edaraven therapy group.ICH model was induced by infusion of autologous whole blood into the caudate-putamen.Rats in sham-operative group were treated the same as above,but no blood injected.Rats in edaraven therapy group were treated with edaraven(3 mg/kg)by peritoneal injection 30 min before operation and once per 12 hours after operation.These rats were killed at 6,24,72,and 168 h after neurologic impairment test with Longa criteria.Brain water content was measured by dry-wet weight method.Malondialdehyde and TNF-alpha in the vicinity of the hematoma were measured by thio-barbituric acid method and ELISA respectively.Results Compared with sham operative group,neurologic impairment score,brain water content,malondialdehyde and TNF-alpha in brain tissues were obviously higher in ICH model group(P0.05).Compared with ICH model group,neurologic impairment score,brain water content,malondialdehyde and TNF-alpha in brain tissues were significantly decreased in edaraven therapy group(P0.05).Conclusion Edaraven has an evident protective effect on injured brain tissue through inhibiting malondialdehyde and TNF-alpha content in the vicinity of the hematoma.

I n January 1990, a distinguished group of 200 occupational therapists and occupational therapy assistants gathered in San Diego to contemplate and plan our future elireerions. These leaders, representing education, practice, ami official American Occupational Therapy Association (AOTA) bodies, considered future scenarios for occupational therapy and developed models for 2lstcentury occupational therapy euucation and practice. The Directions for the Future (OFF) Symposium was a milestone in a process undertaken by the profession. This process for gazing into the future was designed not only to identify future occupational therapy environments but also to plan anel act on models of education and practice that could lead service provision into the next century. Future gazing is an ongoing process but is productive only when actions are taken that invent rather than respond to future events or changes. The process will periodically culminate in actions taken by AOTA and by individuals willing to take leadership for creating change in both our education and practice environments. This article and subsequent Nationally Speaking columns will report information from the OFF Symposium. Additional information from the symposium is available from symposium participants and state association leaders, in articles in OT Week, in 1991 Annual Conference presentations, and from staff in the National Office. Responsibility for our future rests with each of us, whether we are currently in official positions influencing official Association actions Ann p, Grady

Many of the brazing alloys which were investigated were highly promising for sodium-to-air radiator service. Alloy systems of Ni-- Si-- B, Ni-- Cr-- Si-- B, and Ni-- Cr-- Si were especially favorable. Precious-metal alloys were, in general, severely attacked by sodium, as were many of the silicon-free, chromium- free, phosphorus-bearing alloys. Alloys containing manganese, tin, or copper exhibited poor resistance to oxidation at 1500 deg F. In most cases, oxidation was more pronounced at 1700 deg F. For fused-fluoride-tosodium heat exchanger service, the alloy systems Ni-- Cr-P, Ni-- Cr-- Si-- B, Ni-- Si-- B, and Ni-- Ge-- Cr-- Si show promising corrosion resistance. Although the Ni-- Cr-- Si alloy was compatible with sodium, it was severely attacked by the fluoride bath. The binary alloy 88 Ni-- 12 P (alloy A-10) was incompatible with sodium but possessed good resistance to fluoride attack. Tests seem to indicate that complex alloy systems containing varying percentages of silicon and phosphorus as minor constituents may be compatible with both sodium and the fused salts, whereas the binary alloys exhibited compatibility with only one of these testing media. The only brazing alloys found to be compatible with fused sodium hydroxide were precious-metal alloys such as 82more » Au-- 18 Ni. In evaluating the corrosion and the oxidation resistances of a brazing alloy for a specific application, emphasis was placed on the seesawcorrosion and cyclic-oxidation studies, since these tests more nearly simulate the expected operating conditions than do the static tests. It must be remembered, however, that before a brazing alloy is selected for a given operation it should be tested further under the conditions which would closely simulate service conditions.

Abstract The prosperity of new sectors within the aquaculture industry depends to a large extent on how and to what extent individual business firms are able to exploit new opportunities emerging from, e.g. breakthroughs in farming technology, favorable natural conditions, changing consumer preferences and so on. The farming of blue mussels is a new and emerging sector within the Norwegian aquaculture industry, where expectations are high both among politicians and practitioners. In this paper we explore the development of marketing strategies among newly established firms pursuing assumed opportunities within blue mussel farming in Norway. Based on an in‐depth study of eight firms and their management, we provide insight into how and to what extent these firms try to exploit assumed opportunities. Our study reveals several intriguing findings. For example, that new firms only to a limited degree focus on "the market" and also that the managers and their firms differ in their perceptions and utilization of opportunities. Findings are discussed and implications highlighted.


Abstract Multivariate analyses of seven meristic characters from 257 specimens of Aspidoscelis hyperythra from Baja California Peninsula, Mexico, revealed pan-peninsular patterns of morphological variation. We observed a significant morphological shift between southern and northern populations at the Isthmus of La Paz, the location of a Pliocene trans-peninsular seaway that could have separated the two groups for a substantial length of time. However, we did not observe fixed character states, such as number of pale dorsal stripes, diagnostic of southern and northern populations. The co-occurrence in local populations of variable numbers of individuals with five, six, or seven stripes makes peninsular A. hyperythra an unusual member of the A. deppii species-group, where number of stripes is consistent in local populations. Samples from the Cape Region were statistically homogeneous based on the characters analyzed, but samples from the latitudinally expansive northern area revealed a pattern of similarities and significant differences unrelated to distances between localities.


The National Park Service conducted archeological investigations at the Eureka Dunes archeological site (CA-INY-2489) within Death Valley National Park. Proposed developments to protect the unique Eureka Dunes ecosystem would affect less than 1⁄2 of 1 percent of the archeological site. However, the archeological work was designed to investigate the whole site. Archeological field work included mapping, intensive controlled surface collection, and subsurface testing. Over 26,000 artifacts were recovered, the overwhelming majority of which were flaked stone. Chronological data indicate the site was used from as early as 4500 B.C. to late prehistoric times. The Eureka Dunes Site is primarily a surface manifestation, but evidence suggests that different parts of the 4 km-long site correspond, in large part, to different time periods. Numerous fire-cracked rock features were identified at the site and seven of the features were excavated. Because of the large size of the site, even the 42,975 square meters of surface collection and 34 square meters of excavation units completed constitute a small sample, and inferences must be considered preliminary. Nevertheless the investigations yielded intriguing data on the use of Saline Valley obsidian and Last Chance green-grey chert, both available locally and widely traded. Some evidence suggests the fire-cracked rock features may be related to the heat-treatment of chert to make it easier to fashion into stone tools. Definitive interpretations await further research, but these investigations do indicate that the Eureka Dunes Site has the data and integrity necessary to address a number of significant research questions. The site therefore appears eligible for the National Register of Historic Places. Although the current work has mitigated the effects of the proposed developments, monitoring is recommended to ensure protection of the site, and additional research is recommended to realize the site's full information potential.


Recurrent Neural Networks (RNN) were historically successful architecture for Machine Reading comprehension. QANet was the first architecture to achieve higher performance with only convolutions and self-attention. In this paper, we dis-cuss our implementation of this architecture with an emphasis made on the encoder block and the choice of the optimization algorithm. We tested our implementation on Stanford Question Answering Dataset 2.0 [1].


Officially, the COVID-19 pandemic reached Ukraine in March 2020 and came to Ukraine at a time when the national economy was not in the best condition. In fact, the COVID-19 pandemic has transformed not only the structure of the national economy, but also the way of doing business. This is evidenced by indicators that reflect changes in the structure of gross domestic product, changes in the structure of employment and marketing tools.
The COVID-19 pandemic has already led to a financial crisis and a crisis in certain areas and sectors of the economy, but there are those who have benefited from quarantine measures. However, there are industries and areas of activity for which the COVID-19 pandemic has given a good start and revenue growth.
Timely response and targeted action will reduce the negative impact of the COVID-19 pandemic, prevent a decline in business activity, create conditions for the development of Ukrainian manufacturers and reduce the impact of the crisis caused by the COVID-19 pandemic.


NIR-II fluorescence imaging-guided photothermal therapy (PTT) has been widely investigated due to its great application potential in tumor theranostics. PTT is an effective and non-invasive tumor treatment method that can adapt to tumor hypoxia; nevertheless, simple and effective strategies are still desired to develop new materials with excellent PTT properties to meet the clinical requirements. In this work, we arise a bromine-substitution strategy to enhance the PTT of A-D-A'-D-A π-conjugated molecules. The experimental results reveal that bromine-substitution can notably enhance the absorptivity (ε) and photothermal conversion efficiency (PCE) of the π-conjugated molecules, resulting in the brominated molecules generating two-fold more heat (ε808 nm × PCE) compared with the non-substituted counterpart. We declare that the enhanced photothermal properties of bromine-substituted π-conjugated molecules are a combined outcome of the heavy-atom effect, enhanced ICT effect, and bromine-mediate more intense intermolecular π-π stacking. Finally, the NIR-II tumor imaging capability and efficient PTT tumor ablation of the brominated π-conjugated materials demonstrate that bromine-substitution will become a promising strategy for developing high-performance NIR-II imaging-guided PTT agents in the future.


E C.H.O. virus infections are generally regarded as benign self-limiting processes. Clinical illness has been estimated to occur in as many as 85 per cent of infections (Sanford & Sulkin, 1959) and usually consists of a febrile episode, often accompanied by a rash, or an aseptic meningitis with complete recovery. Other mild illnesses such as epidemic diarrhoea in infants and children have been ascribed to particular E.C.H.O. virus types (Sabin, 1960). The association of an E.C.H.O. virus infection with an unusual and rapidly fatal illness is therefore of great interest and is here reported.

These are difficult times for the German economy, like so many others. Germans pride themselves on how export-driven the German economy is. The term 'export world champion Germany' is popular in the German media. But Germany has been vulnerable to the changes in world economic conditions. Germany's economy is predicted to shrink by 5% to 6% over the coming year. Unemployment is over 3.5 million, and is expected to rise well above 4 million over the same period.

ABSTRACT This article examines the asymmetric effects of real exchange rate changes on the domestic output of selected Asian countries. To account for asymmetries, we separate currency appreciation from depreciation and utilize the nonlinear autoregressive distributed lag (NARDL) model. Employing annual data (1973 to 2018), we find evidence of short-run and long-run asymmetries in the effects of real exchange changes on the domestic output of all the countries. This means that currency appreciations have different effects from currency depreciations on the output of the countries. Overall, the results suggest that both currency appreciations and depreciations are contractionary in most cases.


A method was developed for concentrating fish pathogenic virus from sea water using membrane ultrafiltration system and centricon. The method consists of passing large volumes (Ca. 20 liter) of sea water through ultrafiltration (PAN) filter followed by cross-flow filtration method and centrifugation use the centricon (Plus-20). This procedure permitted the processing of 20 liter of sea water which resulted in a 20,000-fold reduction in the volume of water and greater than 90% recovery of the seeded MABV.


Combined with the geological survey information of one box culvert construction project and the design data of the running metro shield tunnel below the box culvert in Guangzhou, the MIDAS-GTS software is used to build 3D and 2D simulation models for analyzing the influence of box culvert construction on operating metro shield tunnel below. The research shows: during the period of soil excavation, structure construction and backfill, the maxi-mum of horizontal and vertical displacement of the running metro shield tunnel locates on the top of shield tunnel segment, which is just under the box culvert across. And the maximum total displacement value is 4.74 mm, which is much smaller than the controlling total displacement value for metro protection. Meanwhile, the maximum sagging moment is 11.8 kN·m, and the maximum hogging moment is-12.3 kN·m, which is also much smaller than the controlling bending moment value for metro protection. It can be concluded that the construction of the box culvert above will not endanger the metro shield tunnel below, and not affect the normal running of this metro line.


Introduction of railways in India was a revolutionary development which played an important part in the overall development of the country. The first railway line was opened to traffic in 1953 and railways remained the only mechanical mode of transport for more than seven decades. Railways were a monopoly on the one hand and on the other they had to carry heavy social responsibility of meeting the requirements of defence, public administration, trade and commerce, development of industry, movement of people for business, employment, education, pilgrimage, family gettogethers and other personal reasons. Railway lines were constructed and services were introduced to meet these requirements even though they were not justified on purely commercial considerations.


A grid consists of high-end computational, storage, and network resources that, while known a priori, are dynamic with respect to activity and availability. Efficient scheduling of requests to use grid resources must adapt to this dynamic environment while meeting administrative policies. This paper discusses the necessary requirements of such a scheduler and proposes a framework that can administrate grid policies and schedule complex and data intensive scientific applications. We present early experimental results for proposed a framework that effectively utilizes other grid infrastructure such as workflow management systems and execution systems. These results demonstrate that proposed a framework can effectively schedule work across a large number of distributed clusters that are owned by multiple units in a virtual organization.

In a three-phase distribution system, due to unequal distribution of single-phase loads, load diversities, the different consumption patterns, and growing penetration of renewable energy resources in smart grids, the problem of unbalanced power flow becomes more challenging. In this paper, we propose a new innovative phase imbalance mitigation (PIM) scheme performed by smart meters. With aid of the proposed optimal phase assignment for 3-phase power distribution input feeders known as phase rearrangement (PR), Electrical storages (ES), and the Renewable energy sources (RES), smart meter owners are inspired to assist the distribution system operator (DSO) in diminishing the phase imbalance. This is achieved by employing a proposed connection point assignment system which has the flexibility of selecting the power input among the three phases and management of ESs and RESs. We model this problem into a mixed integer linear program, where smart meter owners minimize their electricity bill. Simulation results confirm the proposed approach and show smart meter owners will save on their electricity bill and the DSO will get benefit by improving the power quality of the grid and significant decrements of the power flow imbalance. doi: 10.5829/ije.2020.33.12c.08
