Young children bring a variety of experiences to the classroom. A constructivist approach requires teachers to engage students in learning experiences that build upon prior knowledge. To connect new data with preexisting mental constructs, teachers need to be aware of students' prior experiences. Since conventional assessment techniques are often limited to standard readiness screenings in reading and arithmetic, broad areas of experience are neglected. Studies indicate that students who come from homes primed with experiences which parallel the school's curriculum function productively in school activities (Majoribanks, 1991; Midwinter, 1975). Previous studies suggest that experiential differences affect future learning outcomes in science (Harlen, 1985; Kahle, 1990). Therefore, it is necessary to define the factors that underlie extracurricular experiences in science to form the foundation of an experiential science checklist for the identification and remediation of specific deficits. The purpose of the present study is to describe the construction and analysis of the Elementary Science Experience Scale (ESES) (Farenga & Joyce, 1997a), an instrument designed to measure students' out-of-school science-related experience. Method Subjects The sample selected for the study consisted of 349 elementary school students. The students (173 males and 176 females) were from grades three to six. Test Construction Items for the ESES focused on three types of out-of-school science-related activities--science-related inquiry skills, life science-related, and physical science-related--that young students experience. Sources of material for the ESES items included observation of children at play in a learning center, informal interviews with parents and a review of the literature (Mason & Kahle, 1989). A total of 35 items was developed. Each item was evaluated using a four-point scale (ranging from never to about once a week) indicating the frequency with which a student participates in a particular activity. Once the items were constructed, they were reviewed by a panel of five science educators to identify ambiguities. Modifications were made based on their commentary. Procedures Before completing the ESES, the students were told that they were taking part in an experiment to see what science-related activities young people participated in outside of school. Students were instructed to place no identifying marks on the answer sheets and to answer the questions as accurately as possible. At all grade levels, the directions and questions for the ESES were read aloud while students read silently. The students were given time between questions to select their answers. In addition, students were instructed to raise their hands if they were having difficulty, required additional time, or needed any type of clarification. Students had an open amount of time (i.e., as much time as they needed) to complete the ESES. Statistical Analysis To identify the major factors of extracurricular science-related experiences, a principal-components factor analysis of the ESES data was used. Results A varimax rotation yielded three factors: science-related inquiry skills, life science-related experiences, and physical science-related experiences (Table 1). Using a factor loading cutoff of .40, 27 items remained in the solution. The Cronbach alpha reliability coefficient for the total scale was .86. The reliability coefficients were also established for the science-related inquiry skills (r = .79), life science (r = .74), and physical science (r = .78) subscales. These results were similar to those produced in an analysis of an earlier version of the scale (Farenga & Joyce, 1997b).

A hundred and fifty samples of stools were collected from patients suffering diarrhea. Hundred and thirty bacterial isolated (86.7%) were identified 84 (64.6%) belonged to Escherichia coli, 23(17.7%) to Klebsiella pneumoniae, 10 (7.7%) Enterobacter cloacae, 7 (5.4%) to Shigella dysenteriae, 4(3.1%) to Salmonella typhi and 2(1.5%) to Pseudomonas aeruginosa. The ability of E.coli isolates to produce alkaline phosphatase enzyme was tested on MM agar medium along with pNPP. ALP was extracted, the crude extract activity and specific activity was 1.86 unit/ml and 20.44 unit/mg protein respectively. The enzyme purified by precipitating with ammonium sulfate (50-75%) saturation then using ion-exchange chromatography in DEAE-Cellulose ionic exchange column and gel filtration chromatography by using sepharose-6B gel filtration column, to obtained pure ALP enzyme with specific activity 272.73unit/mg, with 13.34 fold purification and yield of enzyme 56.45%. The in vivo investigation for the effect of ALP enzyme on the infection with P. aeruginosa was done using BLBC mice. The results shows that ALP degreased the number of bacteria in liver, spleen and lung with significant differences (P<0.05). Also the results shows a significant differences (P<0.05) in elevated levels of cytokines (IL-6, IL-10 and IL-12) compering with control group.


The article presents the first attempt of a complete analysis of historic studies of Protestantism, published by the Kyiv Theological Academy professors and students in the journal "Trudy Kievskoi dukhovnoi academii" starting from the 1860s to the beginning of the 1900s. The author outlines the main directions of historical studies, including the history of the main religious protestant directions, trends, and movements; the history of theological problems; the history of the modern Protestant movements, aimed at union with Orthodoxy; the history of dogmatic and canonical Protestant principles; the history of the symbolic and liturgical books of religious denominations; research of prereform movements; and biographical studies. The article proves the effectiveness of comparative and hermeneutic methods used by Kyiv historians in determining the specifics of religious phenomena. It has established that a characteristic feature of their historical studies is the consideration of religious phenomena in the broad historical perspective by clarifying the historical preconditions of formation and development of these phenomena. The analysis of historical studies shows transformation in Kyiv historians understanding of the theoretical and methodological foundations of the study of religious traditions different from Orthodoxy. In the works on the history of Protestantism from the 1860s till the 1870s the use of dogmatic-theological approach is common, while in the studies from the 1880s to the beginning of the 1900s the use of church-historical approach is widespread. The first dogmatic-theological approach concentrates on researching only dogmatic principles of a certain religion, while the second church-historical approach pays attention to the definition of the religious phenomenon specificity. The Jjournal publications present the results of the Kyiv Theological Academy professors' and students' involvement in the solution of the actual Church life problems in the end of the 19th– beginning of the 20th century, such as the problem of Anglican and Orthodox Churches dialogue.

Objective
To explore the influence of Rosenthal effect on the psychological status of pregnant women at risk of miscarriage in early pregnancy.

Methods
From January 2014 to June 2015 151 cases of early pregnancy abortion risk women were set as the control group, and was given conventional psychological intervention. From July 2015 to December 2016 135 cases of early pregnancy abortion risk women were named as the observation group by convenient sampling selection, which was given interventionbased on Rosenthal effect on the basis of routine psychological intervention. The Self-rating Depression Scale (SDS) and the Self-rating Anxiety Scale (SAS) score, the introversion and extroversion scores and the satisfaction degree with intervention were compared between the two groups before and after the intervention.

Results
There was no significant difference in SDS and SAS scores, inotropic challenge and extroversion challenge between the two groups before treatment (P>0.05). The scores of SDS and SAS, the inotropic challenge and extroversion challenge scores were 41.45 ± 4.26, 40.34 ± 5.82, 4.76 ± 1.03, 5.55 ± 1.26 in the observation group after intervention, and 47.22 ± 3.93,47.18± 7.04,5.39 ± 1.12, 6.43 ± 1.86 respectively in the control group. There were significant difference in scores of SDS and SAS, the inotropic challenge and extroversion challenge (t=2.215-2.573, P<0.05). The satisfaction rates of the observation group and the control group were 93.32% (126/135) and 74.17% (112/151) respectively, the difference was statistically significant (χ2=5.921, P<0.05).

Abstract It is assumed that a control object is described by the system of non-linear stochastic equations dx= [f(x) + v(z)] dt+ σ(x) dW, t>0, x, zeRn, where Wis a vector of independent standard Wiener processes and vis the control vector. It is further assumed that the process Zis observed, described by dzt = xt dNt + yt (x) dB t i= 1,[tdot] n, x, zeFt n i, where B= col (B1 [tdot], Bn ) is a vector of independent standard Wiener processes and N= col (N1 [tdot], Nn ) is a vector of doubly stochastic Poisson processes with intensity process {(λ1(Zt ), [tdot], λ n (Zt <)), t 0}. It is then shown how the process Ncan be constructed, and for a given sampling process N, sufficient conditions are derived on optimal controls. In addition, the problem is dealt with of selecting an optimal sampling process Nfor a given admissible control law.


In the university education, acquirement of the proper judging ability of the adequate natural and social systems on the basis of the enough knowledge and philosophy is important. Artificial beach in the city is an adequate site for education to realize techniques to create artificial environment. A trial of field education for undergraduate students in multi-disciplinary sciences was conducted in Odaiba Park in Tokyo Port. Students carried out field observation and beach survey by themselves as well as analysis of beach materials. Conditions of this artificial beach were compared with that of natural beaches. Various issues associated with planning of the beach park were discussed through the young users' eyes.


A THz free electron laser is being built in Ariel University. Upon completion it is intended to become a user facility. The free electron laser is designed to emit radiation between 1 and 5 THz. It is planned to operate in the super radiance regime. The anticipated output of the free electron laser is in excess of 150 kW instantaneous power. An essential part of every free electron laser is a device generating a periodic magnetic eld denoting the wiggler. Here we describe a design of a classical Halbach type permanent magnetic wiggler for the THz free electron laser. The main novelty in this paper is the choice of wiggler parameters suitable for operation in the THz frequency range. Considerations such as radiation wave length, wiggler gain and electron optics are taken into account.


This paper presents an application of the canonical duality theory for box constrained nonconvex and nonsmooth optimization problems. By use of the canonical dual transformation method, which is developed recently, these very difficult constrained optimization problems in can be converted into the canonical dual problems, which can be solved by deterministic methods. The global and local extrema can be identified by the triality theory. Some examples are listed to illustrate the applications of the theory presented in the paper.


Labour Authority established in 2019, and the Commission's proposal for a minimum wage Directive of October 2020 are discussed. Furthermore, the new edition manages to add an overview chapter on competition law and labour law, and a chapter on General Data Protection Regulation, since the Data Protection Directive was missing from the previous edition. Considering the size of the volume, it is impossible to delve further content-wise. It can be stated, however, that the volume is true to its title, i.e., the author and his assistants have done a remarkable systematic exposition of European employment law. Although, as a systematic exposition, the book is mostly descriptive, in this reviewer's opinion, it is excellently written, not only linguistically, but sufficiently condensed and sticking to the essential necessary details, successfully avoiding an inflated information overkill. There are no noteworthy shortcomings of the book. The book is written in an understandable manner and is very informative. The relevant legal Acts and their intertwinement are clearly outlined, showing the historical development(s), various theoretical positions and the adopted case law. The individual chapters are logically laid out, with several sub-sections and points. The paragraphs are numerically marked and enable the ease of referencing. Moreover, the more important parts of the text are in bold, allowing the readers to pinpoint to a certain issue much more time-efficiently. Overall, the volume has an extraordinary amount of references, especially from scholarship (albeit predominantly in German). If one were to seek further information on a specific issue, it would be extremely difficult to find a body of work more detailed than the current volume, the same being true likewise for the referenced CJEU case law and its development. However, readers should not expect to find any didactic material in the volume, for instance, cases that students could try to solve. In this reviewer's opinion, the book is an indispensable tool and a must have and most definitely recommended for everyone who is dealing with European employment law (in practice) or is interested in it. This most likely relates to (advanced) students, academics or practitioners in particular, and applies not only to those who do not yet have the reviewed volume, but also to those who possess the previous (first) edition. The current volume is much larger and contains nearly a decade of added information developments. Due to the never-ending developments in EU law, where employment law is no exception, and considering that the content of the volume dates until March 2021, it is signalled in the series' preface that a third edition is foreseen. Hopefully, it will be welcomed slightly sooner than a decade from now. With this in mind, the present volume will prove to be most useful until then.


This study attempts to investigate the impact of supply chain management practices on supply chain management performance in Chinese manufacturing industries. A total of 112 respondents from manufacturing industries of Lanzhou the capital city of Gansu is selected and data is analyzed based on the questionnaires. Customer-supplier relationship, information systems and technology, quality management, corporate culture and material flow management are considered as practices and independent variables and only supply chain management performance is assigned as dependent variable. Descriptive analysis, Pearson correlation analysis and multiple regression analysis are utilized to analyze the data and satisfy the objectives of this research as well. The findings reveal that prediction of supply chain management performance is feasible by customer-supplier relationship in which possess highest correlation (r value is 0.809) and linear relationship (r value is 0.281) with supply chain management performance, whereas information systems and technology has lowest correlation (r value is 0.639) and linear relationship (r value is 0.091) with supply chain management performance.


In this paper, the use of the blended learning pedagogy as a teaching environment is studied. This pedagogy is based on a mixture of collaborative learning, problem-based learning and independent learning. Also, it is realized as a combination of a face-to-face environment and online learning, using a proprietary learning management system. More precisely, the methodological approach implemented by the Arab Open University is explored. The Arab Open University has twelve different branches distributed in eight different countries. In addition, the blended learning course design is described and the fulfillment of the corresponding learning outcomes is investigated. The study concludes that the technology provides with more learning choices. Among the choices is the blended learning that has several advantages and strength when compared to its counterpart, the classical learning. However, there are some challenges that need to be considered as well.


Patterns of global histone modifications have been suggested to be predictors of clinical outcome in many cancers. However, the role of global histone modification patterns in oral squamous cell carcinoma (OSCC) is unclear.

The oral administration of optimal amounts of certain aromatic polycyclic hydrocarbons to young adult female Sprague-Dawley rats resulted in the rapid selective and invariable production of mammary cancer. The earliest cancer was detected at 22 days and every rat had multiple mammary cancers within 60 days. This technique for the rapid induction of mammary cancer facilitates the study of the conditions involved in the formation of breast cancer; hormones are critically involved. Progesterone and related gestational steroids accelerated the onset and growth of mammary cancer incited by the carcinogenic phenanthrene derivatives. Large amounts of estradiol-17beta block the carcinogenesis. Small amounts of this steroid have a permissive effect in carcinogenesis but remarkably block the vast stimulatory effects of progesterone. There are 2 highly effective methods of preventing mammary cancer. Hypophysectomized rats developed no cancer in 8 months. Likewise a very effective method of preventing mammary cancer in rats treated with carcinogens is the simultaneous administration of large amounts of equine gonadotropin which evoke intense ovarian activity. The development of mammary cancer with oral carcinogens is conditioned by limiting amounts of hormones and it would appear that there are common binding sites for carcinogens and steroids in the mammary epithelium.

Mulhaüsler and Harré contend that pronoun systems set out fields of expression 'within which people can be . . . presented as agents of one kind or another'. Despite interest in pronominal forms by various discourse researchers, analysis of pronouns-in-use from this perspective remains underdeveloped. This article undertakes such an analysis, drawing on Rees's theories about the 'distance from the self ' encoded in different pronouns. Our data, from interviews analysed as talk-in-interaction, show participants shifting between pronominal registers as a way of presenting their social world and positioning themselves as agents within it. 'Fourth-person' pronouns allow the distancing of reports of lack of agency from the deictic centre of self and express a 'deontic modality' through which one can position oneself in relation to moral imperatives. Along with shifts into and out of the first-person register, this is notably used to maintain an agentive self-positioning in talk about situations of relative powerlessness.


Surgical management of breast cancer in pregnancy (BCP) requires balancing benefits of therapy with potential risks to the developing fetus. Minimal data describe outcomes after mastectomy with immediate breast reconstruction (IR) in pregnant patients.


Contemporary theory and research have suggested that the family and the school are major institutions that contribute significantly in the development of children and adolescents. The present study thus examined the relationships between dimensions of family and school social environments and various aspects of adolescents' self-concepts. A total of 1192 secondary school students participated in the study. Results indicated that perceived parental behaviors were associated with relation, with family, general school, physical appearance, emotional stability, relations with peers, health, and global self-concepts. Perceived teacher behaviors were associated with relations with family, general school, emotional stability, health, and global self-concepts. In comparison, it was found that the relationship with perceived parental behaviors was a stronger predictor of self-concept than that of perceived teacher behaviors.


Continued technology scaling has enabled the tremendous growth that semi-conductor industry has witnessed in last half century. However, as the technology scales in into the deep submicron era, variability in device parameters and operating conditions is emerging as a major threat to this continued growth. In the face of increasing variability, traditional design approaches that use typical or worst case values can lead to yield loss or increased cost and time to market, causing significant revenue loss in either case. State-of-the-art system-level analysis and design methodologies do not take the impact of variability into account and hence it is natural to question their effectiveness in the presence of variability. We believe that it is imperative that the impact of variability be considered during system level design. Analysis and design techniques that are cognizant of variability can help provide designers valuable feed- back about the impact of variations early on in the design cycle and hence, facilitate better design decisions at the system-level while preventing expensive design re-spins. The specific contributions on this thesis include: (i) system-level variability-aware power analysis methodology while considering the impact of manufacturing-induced variations in effective channel length and operation- induced variations in on-chip temperature, (ii) variation- aware system-level shutdown based power management techniques, (iii) variability-aware voltage level selection to improve the number of chips meeting power and performance targets, and (iv) a methodology for system- level performance analysis under variability, and various architecture level and application level techniques to enable performance recovery in systems affected by variations. Experiments conducted on various Systems-on- chip designs demonstrate that variation-aware design techniques enable significant improvements in overall energy dissipation and performance characteristics. In particular, the resulting distributions are more favorable in terms of reducing the revenue loss due to variations. We believe that the approaches outlined in this thesis are useful with the existing design show with the current technologies as well as in future systems by facilitating research and development in variation-aware application- level and architecture level techniques


Dental age is one of the most reliable methods to identify an individual's age. By using dental panoramic radiography (DPR) images, physicians and pathologists in forensic sciences try to establish the chronological age of individuals with no valid legal records or registered patients. The current methods in practice demand intensive labor, time, and qualified experts. The development of deep learning algorithms in the field of medical image processing has improved the sensitivity of predicting truth values while reducing the processing speed of imaging time. This study proposed an automated approach to estimate the forensic ages of individuals ranging in age from 8 to 68 using 1332 DPR images. Initially, experimental analyses were performed with the transfer learning-based models, including InceptionV3, DenseNet201, EfficientNetB4, MobileNetV2, VGG16, and ResNet50V2; and accordingly, the best-performing model, InceptionV3, was modified, and a new neural network model was developed. Reducing the number of the parameters already available in the developed model architecture resulted in a faster and more accurate dental age estimation. The performance metrics of the results attained were as follows: mean absolute error (MAE) was 3.13, root mean square error (RMSE) was 4.77, and correlation coefficient R2 was 87%. It is conceivable to propose the new model as potentially dependable and practical ancillary equipment in forensic sciences and dental medicine.


The Hamiltonian operator for an exchange antiferromagnet is expressed in terms of the deviations of the spins from the basic ordered antiparallel arrangement By a Fourier transformation the Hamiltonian may be approximately represented as a sum of harmonic oscillator terms, corresponding to spin waves. The role of anisotropy energy in fixing the domain axis is discussed, and the energy levels are calculated for the case of an external field parallel to this axis The ground-state energy includes the zero-point energy of the spin waves and is in good agreement with other theories Formulae are quoted for a Hamiltonian including dipole-dipole interaction between non-isotropic spins


With the diagnosis of IVC agenesis and extensive bilateral DVT, the case was treated with heparin and warfarin, but there was not a considerable response in ultrasound evaluation and symptoms. There is no evidence of pulmonary embolism, and the vital signs were stable. Then the treatment with streptokinase (250,000 IU within 30 min followed by 100,000 IU/h for 72 h, intravenous infusion) was started. After a few days, symptom resolved. At the final ultrasound examination, recanalized DVT was reported. Life‐long treatment with oral anticoagulant was recommended.


A number of methods have been attempted to suppress the shuttle effect in lithium-sulfur (Li-S) batteries to improve battery performance. Conventional methods, however, reduce the ionic conductivity, sacrifice the overall energy density and increase the cost of production. Here, we report a facile synthesis of an acrylate-based hierarchical electrolyte (AHE). This quasi-solid electrolyte is assembled by in-situ gelation of a pentaerythritol tetraacrylate (PETEA)-based gel polymer electrolyte (GPE) into a polymethyl methacrylate (PMMA)-based electrospun network. The structural similarity and synergetic compatibility between the electrospun network and GPE provide the AHE an ester-rich robust structure with a high ionic conductivity of 1.02 10 3 S cm 1 due to the strong uptake ability and the elimination of commercial separator. The S/AHE/Li polymer battery also renders a high rate capability of 645 mAh g 1 at 3C, while maintaining excellent retention at both high and low current densities (80.3% after 500 cycles at 0.3C and 91.9% after 500 cycles at 3C). First-principle calculations reveal that the reduced shuttle effect can be attributed to a strong polysulfide anchoring ability of ester functional groups, while cell modeling shows that the geometric design effectively suppresses polysulfide flux. This in-situ integrated method opens up an avenue for the future development of solid-state and polysulfide redox flow sulfur-based

This study demonstrates fast pulse train switching using a coherent polarization beam combiner with a phase difference detection (PDD) algorithm. Based on the highly stable feedback control obtained with the PDD algorithm, stable burst-mode extraction with an arbitrary duty cycle was achieved with a contrast ratio of 800:1 for a third-harmonic light (347 nm) of a 5 MHz pulsed Yb-doped fiber laser. The proposed method can be effectively used for high-speed switching in high-average-power pulsed laser systems.


In view of the problem that the estimation method of node influence in social network is not comprehen-sive and the Particle Swarm Optimization (PSO) algorithm is easy to fall into the local optimal and the lo-cal search ability is insufficient. In this paper, we proposed a Neighbor Cognitive Discrete Particle Swarm Optimization (NCDPSO) algorithm. Aiming at the problem of influence in social networks, a new node influence measure method is proposed, the three-degree theory is introduced to comprehensively estimate the influence of nodes. In order to improve the global search ability of the PSO, the "neighbor cognition" factor is proposed to enhance the breadth of learning; and the following bee strategy is introduced to pro-pose particle density and survivability to control the number of elite clones, so as to solve the problem of insufficient local search ability of the algorithm. Finally, the validity of the proposed algorithm is verified by testing on real data sets and comparing with other algorithms.

E.M.Forster is believed to be one of the most puzzling authors of the twentieth century.The themes in his novels can be clarified and familiarized when looked into from the perspective of the theories of intertextuality.A synchronic intertextual reading reveals that his Italian novels were meant to advocate the Jamesian sumum bonum ,and a diachronic intertextual reading discloses Forsters attempt in his England novels to devise the means by which the sumum bonum can be achieved.An intratextual reading of Maurice and A Passage to India sees the two extreme novels as explications of the intension and extension of Forsters thematic concerns.


ABSTRACT Heavy metals are among the most common environmental pollutants. Their long-term environmental chronic stress leads to negative impacts on the diversity and abundance of benthic invertebrates. The Luda River, a left tributary to the Struma River, flows through the north-western slopes of Pirin Mountain. An abandoned uranium mine is located in the upper parts of the watershed. The aim of this study was to assess the accumulation of heavy metals in the macrozoobenthos of the river. Four sites were sampled for river state assessment and from two of them additional macrozoobenthic samples were collected for heavy metal analysis in October 2011. In the lower reaches, the reduction of potential habitats, due to sand deposition, and the diversion of river waters showed stronger effect on the benthic communities than the abandoned mine. The benthic invertebrates bellow the mine were characterized with increased contents of Cr, Ni, Co, Zn, Cd, Pb and Cu. The results suggested that the metals accumulated in benthic organisms originate mostly from the water, whereas the accumulated Cd, Cu, Zn and Ni originate from the sediments. Supposedly, there is also biomagnification in the food web.

This study aims to analyze the effect of the implementation of corporate governance on the firm value of non-financial companies listed on the Indonesia Stock Exchange (IDX) during 2017-2019. The research data was obtained from the company's annual reports through the Indonesia Stock Exchange website, and the Diponegoro University Bloomberg Laboratory for the period 2017 to 2019. The final sample used in the study came from 85 companies with 126 data observations. The research sample was analyzed using multiple linear regression with SPSS version 25 and the method used was Ordinary Least Square (OLS). The results show that board size, board meetings, institutional ownership have a positive effect on firm value, audit committee meetings and managerial ownership have a negative effect on firm value, while public ownership and ownership concentration have no effect to value of a company.


Colcemid (COM) was tested for induction of increase of mitotic indices (MI) and c-mito-tic effects in bone marrow celis of male(101/E 1×C 3 H/E 1) F1 mice post single injection (i.p.). The doses of 1 mg/kg of COM were used and sampled at 2,6,10,14 and 18 hour. At 2 h post COM treatment, the MI and c-mitotic effect reached the highest, then decreased from 6 h to 18 h. At 18 h, the Mis decreased to (1 mg/kg) or significaatly below(3 mg/kg) the control level respectively; whereas, the corresponding frequencies of cells in class C-E were still significantly higher than in the controls. The possible mechanism by which COM induces increase of MI and the correalation between c-mitotic effects and induction of aneupoidy were discussed.


immediateearly nuclear antigenproductionand by conventional cell culture. No evidence of mycobacterial or fungal infection, Kaposi's sarcoma, or lymphoma was found. The patient was treated with Zidovudinealone. Because of weightloss and weakness, which are similar to those seen in adrenal insufficiency, endocrinologic tests were run and normal values were found for basal cortisol at 8 h, free urinarycortisol, and adrenocorticotropic hormone. Cortisol response to adrenocorticotrophin was normal. Abdominal CT revealed bilateral and diffuse adrenal gland enlargement, particularly the left one, without affectingmorphology and without localized mass (figure lA). Liver and spleen were normalandno adenopathywasfound.Treatmentwith intravenous phosphonoformate (Foscarnet; leI Pharmaceuticals, Northwich,UK)was started with clinical and radiologic improvementof pulmonary disease and retinitis. After 3 weeks of antiviral therapy, an abdominal CT scanshowedpartial improvement; the adrenalglandvolumewas decreased, the left by 20% and the right by 35%. No calcification or necrosis was seen (figure lB). Despite treatment with Foscarnet, the patient died in December 1988;autopsy revealed thepresenceofHCMVelementsin theadrenal glands.Cultureof adrenalbiopsiesperformeda fewhoursafter death remained negative for HCMV. In this case, despite the absence of adrenal insufficiency, radiologic adrenal features were consistent with an inflammatory reaction, probably due to HCMV as shownby the partial improvement afterFoscarnettherapyand histologic study. Enlargedadrenalglands on CT have been reported in blastomycosis, coccidioidomycosis, histoplasmosis, cryptococcosis, tuberculosis,and metastaticcancer [6-10]. The observations in our case clearly show that enlarged adrenal glandscan be associatedwith HCMV withoutadrenal insufficiency. Assessment by adrenal CT deserves further evaluation in patients with AIDS.

Power analysis is an essential procedure for researchers to use before conducting a main study. Researchers need to pay greater attention to statistical power analysis and have to take a serious risk when they design an interventional study with inadequate samples. In an underpowered study, the researcher may be testing a genuinely effective treatment but fail to recognize its efficacy. Researcher can avoid the likelihood of making an error is related to statistical consideration that are used to determine needed sample size for a study. Researchers are strongly encouraged to conduct power analyses when designing studies, and to avoid scattergun approaches to data analysis (i.e. Undertaking large numbers of tests in the hope of finding 'significant' results). when determining a sample size researchers need to consider the desired power, expected effect size and the acceptable significance level. Because reviewing effect sizes are essential for determining the clinical significance of study findings, researchers would better serve the field of medical and nursing studies if they reported and interpreted effect sizes. The present study is an evaluative study of video assisted teaching module on home care of schizophrenic patients developed for primary caregivers. In this present study, caregivers of schizophrenic patients are the samples. A population survey would be impractical for a low prevalence disorder such as schizophrenia by means of this limitation, sample size must be based on an estimate of effect size that is meaningful in this of the study. The aim of this article is to explain sequential steps in estimating sample size of true experimental randomized control trail.


One of the greatest scientific adventures of all time took place in 1979 when the two Voyager spacecraft encountered Jupiter, sending back detailed information and spectacular pictures of the planet, its satellites and the surrounding environment. The results from this mission were amazing.


Cultural ecology,like any other branches of ecology,follows its own specific developing rules.When a culture is perceived as an aesthetic one,it will not only bring pleasant feeling to people,but also showcase its most moving characteristics.Exploring these characteristics is of significance to developing and renovating advanced cultures and to constructing harmonious society.


. In this study, the effect of adding palm fiber rods to the polyester matrix for sound insulation purposes was investigated. The type of fiber used is short fibers with random orientation with the percentage difference in the amount of fiber in the composite as a comparison. Testing loss of voice transmission using impedance tube method is done to know the ability of material to reduce or prevent sound. The data obtained from the TL test results were analyzed and the STC (sound transmission class) values were calculated on each sample. The best results obtained are in the first and second samples with the percentage of fiber 0% and fiber 30%. The calculated results of the STC values in samples one and two each have 32.1 dB and 31.6 dB which indicates sufficient ability to defeat the loud noise. Based on these results, a composite with a 30% fiber content can be used as a sound insulation material and can reduce waste of palm oil that is underutilized.


Background: It has been reported that baclofen, a drug used in the treatment of spasticity, reduces the severity of withdrawal symptoms and substance use disorders (SUDs) for some psychoactive drugs. Aims and Methods: To evaluate the effectiveness and safety of baclofen in the treatment of withdrawal syndrome and/or SUDs, providing (1) an outline of its pharmacological features; (2) a summary of studies that have suggested its possible effectiveness in the treatment of SUDs, and (3) a review of randomized, controlled trials (RCTs) on baclofen and SUDs. Results: Baclofen tolerability is generally considered to be good. Eleven RCTs investigated its effectiveness in the treatment of SUDs. Of these, 5 RCTs found that baclofen is effective, 5 RCTs found that it is ineffective and the results of 1 RCT were not appreciable because it did not achieve the preplanned level of participation. Conclusions: The number of RCTs on baclofen and SUDs is still low, and their results are divergent. Further RCTs should be undertaken, particularly with higher doses of baclofen. Its administration may be suggested in patients who fail to respond to other approved drugs or who are affected by liver disease that prevents their administration, or in patients affected by SUDs for which no approved drugs are available. Treatment should be conducted under strict medical supervision.


If we think over how literal texts, written by Lee sang and Kim Yoo Jeong, were received the feminity and implemented them, we can find their modernistic identity and aesthetic consciousness. Through the characteristics and writer's consciousness of the Goo-In-Hoe(the nine writer's association) it is revealed that they are dandies of the 1930's. And therefore identity of the 1930's modernity will be guessed through their shaped love and sex. From a view point of that the Goo-In-Hoe members would support the individuality of the art, have a strong self-consciousness and hate material worship measure of the middle class people, members share universal sides of the modernism. And therefore the identity of the 1930's modernity can be guessed through love and sex described by them. Considering Goo-in-hoe members support the originality of arts, have a strong self-consciousness of description and hate materialistic worship of the middle classes, they share an universal sides of the modernity. They have a dandy tendency, especially, which have a strong abhorrence of snobbery, esteem the spirit, and contains a decorative aesthetics and tragic preference. At these points of view, it can be regarded as appropriate that two writers expressed dandyism which has anti-snobbery and aristocratic contradiction. In case of Lee Sang, his dandy love has self-deception and an understanding of technical love. And he looks his love with a little gap, but he suffer agony due to his thought whose making gap is impossible. Kim Yoo-Jeong makes a woman an idol and has defects of love due to mother complex. It seem to make a love an idol, however, his love has strong tendency of egoism. And therefore their love in not for some object but for love itself. When a woman, as their object of love, is implemented in a textual form she appears as a street girl. The woman in texts of two writers is regarded as economic value and her body is made her his private property by the man. The consumption of her body is related with exchange system of capitalism. Relation between the castrate man and the street girl appears paradoxical relation between modernistic dandy, originated from a paradoxial situation of colonial modernity, and the lover. The modernistic dandy of the 1930's situation have their modernistic identity and aesthetics and stand face to face however, they made a paradox of the ideal situation and the real situation.

In the manuscripts of Leonidas Lamborghini's novel, Trento, the comments on the spectator demonstrate the force that acquires the theatrical and narrative dimension in his  work, not only in borrowing the dramatic techniques but especially in considering genres and their) edges. The organization of the Lamborghini's manuscripts has allowed an exhaustive analysis of the aspects of his narrative works and Trento "dramatic texts" as for director's indications or scenic formats, and also the conception of spectator/reader in some of his works. A genetic edition based on the search of itineraries that go and come across the generic borders between novel and theatre presents aspects of interest to think not only this Leonidas Lamborghini's particular work but also to think all his poetical and narrative work, for the procedures and formal works of rewriting are persistent along his creation.


The subjective process associated with image qualit y evaluation is endorsed by human psychophysical and physiological measurements. In the human visual system (HVS), the visual attention (VA) is a crucial element, which q uickly identifies the notable regions of the images, subjectively linked to Regions of Inter est (ROI). These are represented by a binary mask, indicating whether a pixel in the corr esponding image belongs to the ROI. Subjective mechanisms dominate eye movements in the first two seconds of viewing and, due to the high relation between the eye actions an d the VA, eye-tracking tests are used to validate 2D attention models: eye movements are rec ord d and processed to generate a Fixation Density Map (FDM). In the 3D domain, an es s ntial factor for VA among the additional parameters of visual dimension is the sc ene depth. The main objective of this work was to study the im pact of a particular ROI on the subjective quality perception of 3D still images, c onsidering different types and level of noise (or distortion) in and out of the ROI. The 3D Gaze images and eye movement database, obtained from an eye tracking experiment d scribed in [1] and specifically created for performance evaluation of stereoscopic 3D attention models was used. Besides the full public availability, this database has ori ginal images in various HD sizes, all in PNG format and with natural content. Binary masks were generated for each FDM and differ ent types and intensities of noise was added to each corresponding image according to the ROIs. By using the generated binary masks and image pixels positions in the ROI, the noise was added in the image regions located inside or outside the ROI. Subjecti v esting with users observing the images and scoring their quality was done to verify the importance of these regions in the subjective quality evaluation. The images were clas sified according to whether the noise was added inside or outside the ROI, the noise type (Gaussian, Speckle), parameter values (intensity level) and the noisy image view (left or right). The results have shown that Gaussian noise has less impact on the quality than Speckle, with higher intensity level and also when the noise is added to the right view and inside the ROI. This is justified due to the fact that viewers fix their eyes over the ROI during more time, thus perceiving higher distortion. As the amo unt of different image content was small, the information about the dominant eye appea rs to be inconclusive. Changing some parameters is suggested for future works, in such a way that there is more certainty on the results without interferences between analyses. As this work was limited to data contained in the image (bottom-up visual interest), some conc epts related to the visualization context (top-down visual interest), such as rarity or surpr ise, may naturally be included in future works, as well as the characteristic of looking pri marily for human faces or humanoid things. Key-Words: Attention model, bottom-up, depth, eye tracking, FDM , ROI , still images, VA.

Prospective ascription of responsibility is hypothetical, commonly noting or setting conditions for critical judgment or liability if some event occurs or fails to occur, thus determining vulnerability to retrospective judgments. Prospective liabilities can be classified by source, by type or degree (if any) of accompanying control, and by structure or stages. But not all prospective responsibility can be understood in terms of liability. Actual or de facto control over X and/or responsibility for Y (persons, animals, inanimate things, etc.), though they may involve prospective liabilities, may not be responsibilities to any person in particular. Such responsibilities may be called responsibilities in rem and distinguished from those assignable to persons (responsibilities in personam). Though prospective responsibility judgments often provide the most important grounds for retrospective judgments, if the concern is with the meaning of responsibility judgments, retrospective responsibility judgments are more basic. For, while we can understand retrospective judgments even though we know nothing of prospective ones, the opposite is not true 1. Prospective and Retrospective Judgments esponsibility is sometimes ascribed before the fact by persons whose eyes are on the future, and sometimes after the fact by critics and judges looking to the past. Prospective ascriptions of responsibility are hypothetical pronouncements about the future, often to the effect that if some event occurs (or fails to occur), the person now judged responsible for it will then be the proper subject of certain other judgments-for example, those ascribing credit or blame, or liability to punishment or reward. Those further judgments will, of course, be made retrospectively, for they will be about an event that has already occurred or failed to occur. Thus, if George is the one who is responsible for seeing to it that X happens, and then X fails to happen,


The storm that opens Shakespeare's The Tempest is natural by all accounts until the start of the second scene. The Master, the Boatswain, and all the cast and crew aboard King Alonso's ship battle against what appear to be natural forces, real movements of the sky and the sea. As is revealed in the second scene, however, reality is not always what it seems. Shakespeare's cunning turn of natural to supernatural sets the stage for a play that will dive deep into the foaming, seething waves of England's seventeenth-century religious debate. The complexity of Prospero's character is at the heart of this play, and the magician's power, his humiliation and his redemption are the subjects of this article. The understanding of redemption that I will operate under has been drawn from Reformation theology, and while I draw from John Calvin and William Perkins at times, I take an especially close look at the writing of Martin Luther. Martin Luther's understanding of theology, his phraseology, his favourite metaphors, and his translation and accompanying interpretation of the gospel were accessible to the people of Shakespeare's England. While I do not seek to prove that Shakespeare is a Lutheran or that he has an affinity for Luther's doctrine, I am convinced that a careful study of The Tempest will reveal that Luther's "gospel for the masses", and particularly Luther's understanding of Christian redemption, are worked out within the conflict of the play.


A virtual prototype model of a new type of 6-PSS parallel structure was established.The stiffness,the precision,and the layout of the drive in the 6-PSS parallel structure,which was used in the supporting system of the secondary mirror in our 2-meter level astronomical telescope,were better than those in a 6-SPS parallel structure.There are seven parameters in the model to define the structure.The paper focuses on the analysis of the relation between stick force and elevation angle,which needs to be particularly and carefully considered in applications to telescopes.We also derived a method for setting the parameters,which allows the states of stick force to change rather weakly and limits the maximum stick force for the range of the elevation angle of 0° to 90°.


Digital human resource management can improve the organizational and operational efficiency of enterprises.In order to improve the efficiency of enterprise digital management and solve the problems of low security level and insufficient stability of 2D face recognition, we introduce 3D face recognition into the digital human resource management system. We propose a face recognition method based on a multistream convolutional neural network and local binary pattern and build a digital face recognition management system. We first build the system computer vision scene. Then a local binary mode facial expression feature extraction scheme is designed according to the depth camera image extraction method. Considering that face 3D features are easy to be missed, we build a multistream convolutional neural network to learn facial 3D features. Finally, we validate the effectiveness of the method in selecting a public face dataset. Experiments prove that our method can reach 98% face recognition accuracy, which is significantly better than other methods.


The analysis of $\gamma$-ray flux variability along with the parsec-scale jet kinematics suggests that the high-energy radiation in the BL Lac object S5 0716+714 has a significant correlation with the mm-VLBI core flux density and with the local orientation of the inner jet flow. For the first time in any blazar, we report a significant correlation between the $\gamma$-ray flux variations and the variations in the local orientation of the jet outflow (position angle). We find that the $\gamma$-ray flux variations lead the 7~mm VLBI core flux variations by 82$\pm$32~days, which suggests that the high-energy emission in S5 0716+714 is coming from a region located 3.8$\pm$1.9~parsecs closer to the central black hole than the "core" seen on the mm-VLBI images. The results imply a strong physical and casual connection between $\gamma$-ray emission and the inner jet morphology in the source.

The corrosion of the nitric acid multiple-boiler made of 304L SS was studied by optical microscope,SEM and other surface technique.The experimental results show that the non-sensitive intergranular corrosion takes place on the 304L SS of the nitric acid multiple-boiler at 89℃,55% nitric acid.The corrosive medium diffuses towards both the steel inner along grain boundary and both side of grain boundary.The P content in grain boundary is higher 2 order of magnitude than that in grain,which induces the potential difference between the grain and grain boundary in corrosive medium,and resultes in the corrosion on the non-sensitive steel.


Multi species turbulence in inhomogeneous magnetised plasmas is found to exhibit symmetry breaking in the dynamical alignment of a third species with the fluctuating electron density and vorticity with respect to the magnetic field direction and the species' relative background gradients. The possibility of truly chiral aggregation of charged molecules in magnetized space plasma turbulence is discussed.


In this paper, the tearing behavior of thin polymer sheets was studied experimentally and numerically. First, the specific essential work of fracture for thin biaxially oriented polyethylene terephthalate (Mylar) was measured experimentally. Double-edged notched tensile specimens of Mylar with three different thicknesses and varying ligament lengths were tested. Load-displacement graphs were formed, and the total internal energy was evaluated, from which the specific fracture energy was determined. Next, a finite element analysis was performed to predict the tearing response of polymer sheets. The finite element model incorporated a user-defined cohesive element to properly represent the structural behavior of a thin polymer sheet in the presence of damage, including the propensity of the sheet to wrinkle. The results indicated that the measured specific essential work-of-fracture values were nearly identical for the three separate thicknesses, which confirmed that it is indeed a material property of the ...

Scanning force microscopy (SFM) belongs to a class of real-space microscopic techniques, which combine high spatial resolution, 3-D imaging capabilities, and contrast mechanisms based on specific materials contrast. In particular, in the field of polymer science and technology, SFM quickly developed into an indispensable characterization technique and has found widespread use. In this article the application of SFM to polymers is discussed based on a selection of topics covering the whole breadth from topography imaging to mapping of surface properties and studies of dynamic processes in real time. The basic concepts and modes of SFM, as well as some rudimentary theory, are introduced as a self-supporting basis for the following sections. The visualization of the morphology and ordering of polymers at various hierarchical levels is reviewed starting from the visualization of single macromolecules, chain packing, and surface crystal structures. The imaging of lamellar crystals, hedrites, and spherulites by SFM approaches is discussed, followed by studies of the effects of deformation and processing, as well as studies on the morphology of latex particles and fibers. The mapping of surface properties and composition in the heterogeneous and surface-modified polymer systems via the spatially resolved measurement of adhesion and friction forces, as well as surface mechanical properties, are covered. The final section is focused on in situ studies of structure development and dynamic processes, including polymer crystallization, followed in real time by SFM.

The aim of this paper is to examine the impact of flexicurity upon Italian regional labour market performance in the employment of disabled people. For this purpose, we implement a two step analysis by using Italian regional data for the period 2006-2011. In the first step, we verify by means of three flexicurity indices that Northern and Central regions show a higher degree of flexicuritythan Southern regions. In the second phase of our analysis, we verify by estimating an augmented matching function that flexicurity increases the probability of finding employment for a disabled person. In particular, we test that the flexicurity indicator that gives more weight to the economicindependence of disabled people represents the in dicator that most favors the labour matching process.


We hope that you enjoyed reading Part I of Pitfalls and limitations of Radionuclide and Hybrid Imaging. In Part II, we continue to cover several other important and interesting topics. Radionuclide infection imaging is a common technique performed in nuclear medicine departments worldwide. New hybrid imaging systems and radiopharmaceuticals have been developed. Dr Glaudemans and coauthors have reviewed the Pitfalls and Limitations of Radionuclide andHybrid Imaging in Infection and Inflammation, and they focus on general pitfalls that may cause problems regarding the acquisition and interpretation of the scans performed in cases with suspected or known infectious and inflammatory processes. Additionally, they cover important pitfalls that can occur in specific clinical entities. Normal physiological and benign pathological variants of 18-fluoro-2-deoxyglucose positron-emission tomography scanning: potential for error in interpretation (1996) was one of the most popular seminars' article. Drs Corrigan and Cook have revisited this topic on Pitfalls and Limitations of PET/CT (18F-FDG and non-FDG tracers) extensively and reviewed elegantly to provide a broad perspective of common variants and artifacts encountered in PET/CT imaging with a large number of illustrative clinical cases. Radionuclide hepatobiliary and gastrointestinal system remains an important technique among radionuclide investigations. Dr Chen Low and coauthors elegantly provide a broad perspective of common variants and artifacts encountered while imaging the hepatobiliary and gastrointestinal system. PET brain imaging is an important technique for evaluating several neurologic and psychiatric conditions. However, the clinical utility of PET brain imaging relies on protocol and procedure performance, as improper techniques may lead to


A thin, board-to-board zero force insertion and withdrawal connector having a housing containing a plurality of contacts with a first end portion of the contacts secured therein. A pair of parallel rows of rib-like elements extend along the length of the housing and define a U-shaped slot into which the edge of a circuit board can be inserted. The ribs form grooves therebetween which are perpendicular to the rows of ribs. The other end portion of each of said contacts extends downwardly into a groove towards the inner sides of said rib-like elements defining a side of said U-shaped slot, and then further extends upwardly towards the outer side of said rib-like elements. A plate is positioned along the length of said housing and secured thereto by a flexible hinge which divides the plate longitudinally along its length into two sections. A first of these sections extends over the said other end portions of said contacts. The other section of said plate has inclined planes formed on the inner surfaces thereof. A flat strip of material, which also has inclined planes on one surface thereof, fits in-between said second section of said plate and said housing, with the inclined plane surfaces mated to each other. By moving the flat strip in a first direction the said plate is pivoted about its flexible hinge so that said first section thereof forces the said other end portions of said contacts down into said U-shaped slot and against the edge of a circuit board inserted therein.

This longitudinal study investigated the association between radiographically diagnosed deformed condyles (DCs) and craniofacial growth in orthodontic patients who were not selected for DC. The study started in 1970 with 135 children aged, on average, 12.5 years, of whom 21 were diagnosed with DC. Twenty years later, 56 of the 135 initial participants were investigated again. Their average age was 31.9 years, and 14 were diagnosed with DC. Of these 14, only 4 also had DC at the start of this study. Juveniles with DC had a shorter ramus, a shorter basion–sella dimension, and a vertically underdeveloped alveolar process in maxilla and mandible. Comparison with longitudinal growth data of normal subjects indicated that vertical deficits already existed before the age of 10.5 years. In adults, the vertical growth deficits had disappeared and were replaced with horizontal deficits, like a shorter mandibular diagonal. It looks like the mandible had been compensating its initial vertical growth deficit at the expense of a more retrognathic profile. It is concluded that DC emerged before the growth spurt had started and was associated with growth deficits that changed in the course of time from vertical to horizontal; these growth deficits involved the mandible as well as the maxilla. Finally, these data inevitably lead to reflections on the cause of DC, and whether it may have some relationship to the development of idiopathic condylar resorption. Spontaneous occurrences, as documented in this study, suggest that phenomena such as idiopathic condylar resorption also could arise without any obvious initiating cause.


Abstract: Nowadays, health is wealth as recently we all faced Covid-19 disease. If take into an account, maintaining our health was much important for that we must always do diet, mediation, and exercising, these are the most vital factors for measuring a healthy life. To be free from injuries and obtaining the foremost from our workout proper form of exercise is important. Doing an excessive amount of repetition and over training can cause muscle soreness. Unceasingly doing exercise incorrectly may eventually cause severe future injuries. The rest between the sets ought be optimum depending on the repetition of the exercise, what muscle group is being trained and the load that's being place within the muscle. Maximum Muscle hypertrophy is achieved with the proper type of exercise. The goal of the project is to build an exercise repetition counter and form corrector in a way so that the optimum growth is often achieved with the help of cutting-edge technology. We tend to the area units that are able to observe and notice errors in user's activity (pose) by effectively supporting some threshold deviation between the limb angles. If a person is doing exercises with the help of this system, the user\'s form is checked (corrections in form also will be given if any) repetition's status and count is displayed, beside this the AI dietitian calculates the performance, total workout, etc. and produces the detailed report of that user. This can increase muscle hypertrophy and scale back the injury


In this paper, the distributed state estimation problem is studied for a class of state-saturated power systems subject to Denial-of-Service (DoS) attacks. The randomly occurring DoS attacks is modeled by a series of Bernoulli distributed stochastic variables with known probability distributions. The aim of this paper is to design a distributed estimator ensure, in the presence of both cyber-attacks and state saturations, the desired estimation performance is satisfied. By virtue of some typical matrix inequalities, a tight upper bound of estimation error covariance is derived. The estimation parameters are obtained with the help of the solution of a set of Riccati-like difference equations. The developed recursive algorithm is independent of the global information and thus satisfies the requirements of scalability and online application. Finally, a practical example is developed to verify the validity of the designed estimator.


The standard microelectrode technique was used to analyse light and low-temperature induced transmembrane potential changes in mesophyll cells. Four different plant species (Conocephalum conicum, Vicia faba var minor, Helianthus annuus and Arabidopsis thaliana) were chosen for the experiments. Changes in their generator potentials (GPs), action potentials (APs) and voltage transients (VTs) were measured after the addition of different ion channel modulators. The following conclusions can be drawn from these sets of experiments: 1. The mesophyll cells of the liverwort Conocephalum conicum generate APs in response to illumination or drops in temperature. Its photosystems are engaged in light-perception-connected AP-induction. AP-generation can be a result of transient proton-pump inhibition as well as calcium channel activation. 2. The mesophyll cells of higher plants are unexcitable. A temperature drop elucidates transient voltage changes due to calcium influx. 3. The calcium-dependent membrane voltage changes show dose-dependent characteristics. They do not propagate and cannot be evoked by electrical stimuli, thus voltage-independent Ca 2+-channels must be involved in their ionic mechanism. 4. In Conocephalum conicum, low temperature can separate membrane processes occurring on the plasmalemma from those on the tonoplast. 5. Differently induced VTs in Conocephalum conicum use the same pool of calcium ions.


Effects of adding PVA,PMMA,PVP and their combinations in PVDF/DMAc system on phase inversion process and membrane structure parameters and performance were investigated according to the casting solution viscosity,gel point temperature and dynamic behavior of phase transformation and combined with SEM and AFM techniques,bubble point pressure and hydrophilic contact angle etc means.The results showed that the viscosity and gel point of the casting solution which blended PVA,PMMA and PVDF separately increased,resulting in delayed demixing and slowing down the phase separation and curing speed.The macropores and sponge-like structure in membrane internal were interfingering and hydrophilic of the films were better.The PVP and PMMA blending PVDF system produced instantaneous demixing,and liquid-liquid demixing and liquid-solid demixing coexisted,the macropores in membrane internal were transparent and the support layers were dense,showing excellent separation performance.PMMA can effectively improve the surface roughness of the ternary blend films.

Dongba characters are hieroglyphs still used by The Naxi nationality in Yunnan province, and have a long history which is called "living fossils" of characters. In view of the neglect of the influence of similar characters on the recognition accuracy and the absence of the construction and application of relevant models in the existing studies on Dongba characters, this paper proposes a multi-scale feature fusion based the character recognition model for Dongba characters. First of all, due to the lack of Dongba characters data set, two Dongba characters data sets (including DB1424, a common data set, and DBS20, a data set about similar characters) are constructed. Then, the design of this model mainly uses ResNet34 as the basic network model. While extracting the ResNet34 network features of the input image, the traditional feature extraction algorithm is used to extract the directional gradient histogram (HOG feature) of the image that can better reflect its structure and shape. The structural features of shallow layer and the semantic features of deep layer in the network are fused with HOG features to form a combined feature, and finally the Softmax classifier is used to output the results. The results of the experiments illustrate that the accuracy of the recognition model proposed in this paper on DB1424 and DBS20 are 89.712% and 94.729% respectively. Compared with other deep learning models, the model proposed in this paper has better learning ability, and the precision and recall rate are also higher.


Wood anisotropy is induced by the specific deposition of anatomical elements during the life of the tree. The anisotropy becomes evident when acoustical properties are measured in the different main symmetry directions.The first approach for the estimation of wood anisotropy was to calculate the ratios of longitudinal and shear velocities in natural symmetry directions. The modeling of wood structure is required in order to relate the anatomical structure to the acoustical behaviour of wood.The second approach for wood anisotropy interpretation was to compute acoustic invariants and to average them. Considering that those quantities are insensitive to the direction of propagation, they can act as references for anisotropy investigation. Combining the values of invariants in the three main symmetry planes yields a single global value that characterises each species.Values of invariants for 15 species (conifers and broadleaves) are given.


The chemical composition of terrestrial planetary atmospheres can be critically influenced by the presence of trace species, which in turn, can act in catalytic cycles, affecting the concentrations of major atmospheric gases, by providing alternative chemical reaction routes (i.e., chemical pathways). Since the number of chemical species and reactions in such complex systems can be very large (and hence, also the number of chemical pathways), it is, generally, a challenging task to identify the important chemical pathways that determine the abundance of major species. Therefore, effective methods for the investigation of such reaction networks are required. In order to analyze the CO2-dominated atmosphere of Mars, we use a new analysis tool (i.e., Pathway Analysis Program - PAP), which is capable of identifying and also quantifying all chemical reaction pathways in a reaction network. For this study, we apply PAP to the Caltech-JPL 1-D Mars photochemical model to identify and analyze the dominant chemical processes involved in CO2-production in Mars' atmosphere. Results of our analysis with respect to the dominant catalytic chemical cycles, governing Martian atmospheric CO2 will be discussed.


Abstract : Expert Systems (ES) are characterized by containing the knowledge of a single human expert. Most ES today operate in a 'standalone' basis, providing expertise in a specific domain. However, managers making strategic decisions on complex topics require the coordination assessment and evaluation of knowledge from multiple human experts. Standalone knowledge bases should be loosely or tightly coupled together to form a network of coordinated Distributed Expert Systems (DES). To facilitate this, a 'meta-ES' could be designed to access and control these distributed knowledge bases, thus providing users with a single entry point into a vast knowledge network. In the U.S. Navy submarine is constructed of compact, high energy systems, safety is paramount to prevent both personal injury and material damage during maintenance evolutions. The Ship's Duty Officer (SDO) is responsible for the safe and effective execution of all maintenance aboard ship. Thus, he needs to be knowledgeable of how maintenance on one system will affect the operation of other systems. Since the SDO requires many sources of expertise, automating a submarine maintenance process is an appropriate DES application. (RRH)


Objective To study the gastroesophageal pH changes in patients with hypertrophic pyloric stenosis by 24 hour pH monitoring before and after operation.Methods 28 patients with hypertrophic pyloric stenosis and 21 normal children were subject to 24 hour gastroesophageal pH monitoring.Results The acid reflux was observed on the pre operative group compared to that of the normal. 57.1% patients showed gastroesophageal reflux. Three to seven days post operatively, gastroesophageal acid reflux decreased dramatically while duodenogastric reflux increased. 64.2% patients presented with duodenogastric reflux or mixed gastroesophageal reflux after the operation. The gastroesophageal reflux decreased significantly one month postoperatively.Conclusions Children with hypertrophic pyloric stenosis mainly present with acid gastroesophageal reflux before operation, and present with duodenogastric reflux and mixed reflux after operation. With the improving in the function of the pyloric canal, refluxes should be alleviated.


We define free, covariant Euclidean Bose and Fermi fields and establish their relation with the corresponding relativistic free fields. Using this correspondence we prove a Feynman-Kac formula for boson-fermion models.


We consider the issue of stability for retarded delay equations with multiple delays. We show how a renorming of the energy state space can be used to obtain a dissipative inequality which implies exponential stability of the solution semigroup associated with the delay differential equation. We provide a detailed proof for the scalar case with two delays, then indicate how the proof extends to systems and multiple delays


The cumulative yields of 48 fission products in the mass range of 77--153 have been measured for the $^{232}\mathrm{Th}(n,f)$ reaction with the average neutron energies of 7.46, 13.4, and 18.0 MeV using an off-line \ensuremath{\gamma}-ray spectrometric technique. Fast neutron beams were generated using the $^{9}\mathrm{Be}(p,n)$ reaction with the proton energies of 25, 35, and 45 MeV from the MC-50 Cyclotron at the Korea Institute of Radiological and Medical Sciences. Post-neutron mass chain yields were obtained from the cumulative fission yields using the charge distribution correction of the medium energy. From the mass yield data, the peak-to-valley ratio, average light mass, and heavy mass, as well as the average neutron numbers were obtained. The fine structure of the mass yield distribution in the $^{232}\mathrm{Th}(n,f)$ reaction is explained by considering the nuclear structure effects such as the even--odd effect and shell closure proximity. The effect of deformed shells closure proximity arising due to the octupole deformation of fragments is discussed. The difference in the mass yield distribution between the $^{232}\mathrm{Th}(n,f)$ and $^{238}\mathrm{U}(n,f)$ reactions at various excitation energies is explained based on the different types of potential energy surfaces between the two fissioning systems. The role of excitation energy on the standard I and standard II asymmetric mode of fission is also discussed. In the $^{232}\mathrm{Th}(n,f)$ reaction with the excitation energies of 11--13 MeV, the onset of symmetric product yields, peak-to-valley ratio, average light mass, and heavy mass, as well as the average neutrons number have been observed, which are explained from the point of second chance fission.


Asimple, precise, accurate and rapid High Performance Thin Layer Chromatography (HPTLC) method was developed for the simultaneous estimation of Diclofenac Potassium and Tizanidine Hydrochloride in tablet dosage forms. A CAMAG Linomat IV Sample Applicator in Precoated silica gel Plate 60F 254 (Merck) and the mobile phase solvent system consisting of Toluene: Isopropyl alcohol:Ammonia (30:20:2.5)were used.The drugswere scanned for Rf values in the scanner at the wave length 280nm. The Rf value of Diclofenac Potassiumand Tizanidine were 0.62 - 0.69 and 0.85-0.92 respectively. The Linearity forDiclofenac PotassiumandTizanidineHCLwere in the range of 3000 to 7000 ig/ml and 120 to 260 ig/ml.Results of the analytical method were validated statically, and by recovery studies. The Proposed method can be successfully used to determine the drug contents ofmarketed formulation.


A LED street lamps design with nonsymmetrical light distribution along the road was proposed in this paper. With rectangular light distribution pattern, it reduces the intervals of the largest intensity to decrease the direct glare for drivers. Comparing with the symmetry design along the road, its threshold increment reduced 50% in the same condition.


Broadcasting is an efficient alternative to unicast for delivering popular on-demand media requests. Broadcasting schemes that are based on windows scheduling algorithms provide a way to satisfy all requests with both low bandwidth and low latency.
 Consider a system of n pages that need to be scheduled (transmitted) on identical channels an infinite number of times. Time is slotted, and it takes one time slot to transmit each page. In the windows scheduling problem (WS) each page i, 1 ≤ i ≤ n, is associated with a request window wi. In a feasible schedule for WS, page i must be scheduled at least once in any window of wi time slots. The objective function is to minimize the number of channels required to schedule all the pages.
 The main contribution of this paper is the design of a general buffer scheme for the windows scheduling problem such that any algorithm for WS follows this scheme. As a result, this scheme can serve as a tool to analyze and/or exhaust all possible WS-algorithms.
 The buffer scheme is based on modelling the system as a nondeterministic finite state machine in which any directed cycle corresponds to a legal schedule and vice-versa. Since WS is NP-hard, we present some heuristics and pruning-rules for cycle detection that ensure reasonable cycle-search time.
 By introducing various rules, the buffer scheme can be transformed into deterministic scheduling algorithms. We show that a simple page-selection rule for the buffer scheme provides an optimal schedule to WS for the case where all the wi's have divisible sizes, and other good schedules for some other general cases. By using an exhaustive-search, we prove impossibility results for other important instances.
 We also show how to extend the buffer scheme to more generalized environments in which (i) pages are arriving and departing on-line, (ii) the window constraint has some jitter, and (iii) different pages might have different lengths.


Proposes to demonstrate the construction of a political project having as central axis the figure of Manuel Gonzalez Prada in the framework of the intense cultural activity that developed this intellectual. It distinguishes two moments: the first, from 1886 to 1903; The second, from 1904 to 1909. It postulates that in the first stage it travels from the criticism of the political scenario of the postwar Pacific with the Constitution of the political project which aspires to the Presidency of the Republic, towards the second, which desists from that purpose and assumes an anarchist position.

Ethylene dehydrogenates Ir(H)2FL2 (L = PtBu2Ph) to give the metalated species 1 and 2. These metalated species catalyze the exchange of deuterium from C6D6 to ethylene, and to tBu and ortho phenyl sites of coordinated L. This exchange is proposed to benefit from π-donation from F to Ir.


Learning architecture has always been an arduous, multi-threaded process requiring high skills at entirely different areas of knowledge including objective issues like mathematics, geometry or physics as well as subjective ones like art & psychology. If the objective issues might be described & accordingly taught using known scientific & rational methods the subjective ones were difficult to put into some scientifically verifiable frames. One of the main subjective factors about architecture is its perception both from author's & visual recipient's point of view. There might be a total discrepancy between these two points of view; moreover, some architecture solutions might be approved among connoisseurs but thoroughly rejected by the unprofessional audience. De gustibus non disputandum est as famous Latin maxim says. On the other hand, we mustn't forget that architects don't create their projects for themselves only (as unfortunately it seems too many of them) but they should reckon with the opinion of their payers. Perhaps the perception of architect's work, methods of its creation, stimulation and in some cases manipulation is the most important knowledge for an architect if he wants effects of his toil to be appreciated. The article puts forward the methodology of teaching architectural perception in Szczecin ZUT Architecture Faculty. The methodology is based on three – model education system consisting of technological, humanistic and critical models and deriving from the three worlds theory of K.R.Popper.

There is a description of work being carried out by the authors through the TARDIS (Time and Resource Distribution in Schools) Project, financed by the Funding Agency for Schools. The need for proper analysis of learning needs and consultation with stakeholders before embarking on calendar change in schools is stressed.


In a recent article, Professor Michael Wells attacks what I had characterized as "the Hart and Wechsler paradigm" for analysis of Federal Courts issues.l To summarize crudely, Wells claims that the Hart & Wechsler paradigm, which we agree reflects the still dominant approach to Federal Courts scholarship, is descriptively impoverished and normatively inadequate, and he offers a "pragmatic" alternative. Wells's article raises important issues for those who teach and write about Federal Courts law. His essay also calls attention to questions about the notion of examining legal issues by reference to a "paradigm" that are equally pertinent to other subject matters. A brief response, addressed to some of these issues, therefore seems warranted.


This title offers a fascinating look at the efforts of the J. Paul Getty Museum to preserve and expose a stunning 16th century triptych. Maerten van Heemskerck (1498-1574) was one of the most active and inventive Dutch painters of the 16th century. Over the course of his long career, he created lively mythological scenes, dramatic altarpieces for guilds, and smaller works for wealthy individuals. Regrettably though, several of his religious paintings were destroyed by Protestant iconoclasts in 1566. One of his extant masterpieces, the "Ecce Homo" triptych of 1544, was brought from the National Museum in Warsaw, Poland, for treatment and study at the J. Paul Getty Museum as part of the Conservation Partnership program. Richly illustrated, this book documents the dramatic process of revealing the brilliance of a 16th-century masterpiece.
