Purpose: Vocational rehabilitation (VR) programs aim to facilitate work participation. However, there is no universal framework to describe the functioning of individuals who participate in VR. The objective of this paper is to report on the Core Set for VR based on the International Classification of Functioning, Disability and Health (ICF) by the World Health Organization (WHO). Methods: A formal decision-making and consensus-based process was conducted based on the evidence from four preparatory studies. Twenty-three international experts chosen by WHO Region and expertise in VR attended the consensus conference. Results: Ninety ICF categories were included in the comprehensive Core Set (activities and participation = 40, environmental factors = 33, body functions =  17), while the brief Core Set included 13 second-level categories (activities and participation = 6, environmental factors = 4, body functions =  3). Conclusions: The expert opinion and evidence-based Core Set could serve as an international standard for what to measure and report concerning functioning of individuals in VR. The Core Set could also provide a common language among clinicians, researchers, insurers, and policymakers in the implementation of successful VR. Further testing and validation studies are encouraged. Implications for Rehabilitation Vocational rehabilitation is a multidisciplinary and multi-stakeholder process, which aims to reduce or eliminate the burden of work disability and facilitate work participation. The International Classification of Functioning, Disability and Health (ICF) provides a framework to describe and measure the functioning of individuals who are in a vocational rehabilitation program. The ICF Core Set for vocational rehabilitation provides us with a list of functioning domains in our effort to examine vocational rehabilitation or return-to-work outcomes and the multiple factors associated with vocational rehabilitation. The ICF Core Set for vocational rehabilitation can be used in clinical rehabilitation setting and rehabilitation research, and further steps to ensure the robust measurement, documentation, and reporting of the Core Set in rehabilitation are being planned.


use of conventional investment appraisal techniques and the criteria used to assess management performance may discourage investment in AMT. The paper presents some of the most interesting results of two surveys of large manufactunrng companies in the Czech Republic that were carried out in 1998 and 2005. The results gave us the possibility to identify main changes happened during the period of seven years. Moreover, we are able to compare our findings with the results of similar surveys conducted earlier in the UK and the USA. We do believe that our results and recommendations can help engineers and AMT project promoters in general in their effort to get their projects financed and to put the technology in practice.


Tumefactive lesions represent a rare radiological manifestation of multiple sclerosis (MS) seen in only a few cases per one thousand patients [1]. Often, their pattern appears to be open ring-enhancing, with the incomplete portion abutting cortical gray matter or the basal ganglia [2]. As implied by the name, tume factive MS can be challenging to diagnose correctly prior to obtaining tissue samples [3]. Mistaking tumefactive MS for a brain tumour is a pitfall that should not be underestimated [3], as in these cases microsurgical resection carries unecessary risks for the patient. We present a case of an unusual closed ringenhancing appearance of tumefactive MS along with an outline of our patient management that accounted for this rare event.

AIM:To evaluate effects of landiolol on heart rate variability(HRV)and QTc interval during tracheal intubation in patients with type Ⅱ diabetes. METHODS:Forty patients with type Ⅱ diabetes were randomly allocated either to landiolol group(group L)or to control group(group C). A bolus of 0.1 mg·kg-1·min-1 landiolol was administered to the group L for one minute at two minutes before tracheal intubation and followed by a continuous infusion at a rate of 0.04 mg·kg-1·min-1;group C received the same volume of saline.The changes in HRV and QT interval were recorded and compared between the two groups at following time points:preinduction(T0),intubation(T1)and 1min(T2),3 min(T3),5 min(T4)after intubation.RESULTS:At T1 to T4,LF/HF were lower significantly in group L than those in group C.QT intervals were lengthened remarkably at T1 to T4 in the group C than those in the group L(P 0.05).CONCLUSION:Landiolol can inhibit effectively the sympathetic nervous system activity and improve the balance between the sympathetic and parasympathetic nervous system.Landiolol can also shorten the QT interval prolongation associated with tracheal intubation.


Breast cancer is one of the world's most frequent female malignant tumors,and its morbidity and mortality has a tendency to rise year by year and the trend of getting younger.Because of a breast cancer early signs and symptoms are not obvious,so more easy to be ignored.So the early detection and diagnosis is particularly important in improving survival.With the progress of science and technology in recent years,MRI techniques have also been described from pure anatomy to molecular biology,pathology,physiology and the direction of functional imaging.This article of MRI in the diagnosis and treatment of breast cancer and clinical value of the current state of research on are reviewed.


I sketch Mike Hopkins's proof of the Landweber exact functor theorem, and offer some related perspectives and notations. In 1966 Pierre Conner and Ed Floyd [3] proved the following remarkable theorem: Complex K-theory is algebraically determined by complex bordism. To be precise, there is a ring homomorphism Td : MU∗ → K∗ (the "Todd genus") and a natural isomorphism from the resulting tensor product: MU∗(X)⊗MU∗ K∗ → K∗(X) . Their proof required prior knowledge of the existence of the homology theory given by Bott periodicity. But it opened the possibility that other interesting homology theories might lie hidden inside complex bordism. Ten years later, Peter Landweber [6] provided a simple condition on an MU∗-module M guaranteeing that X 7→MU∗(X)⊗MU∗ M is a homology theory—and hence (according to George Whitehead and Ed Brown) is representable by a spectrum. This gives a construction of the Bott spectrum independent of Bott periodicity. It doesn't obviate the relevance of Bott periodicity, since it does not explain the relationship between the theory thus constructed and complex vector bundles. But Landweber's theorem opened the way to the wholesale construction of spectra, many of which have played dominant roles in algebraic topology throughout the intervening forty years. This note has several loosely connected aims, all modest and none very novel. The theory of formal groups and their occurence in topology has been expressed many times in quite sophisticated terms ([11, 5, 4, 8, 10] are some examples). We hope here to achieve the level of generality and naturality one finds in those sources, without requiring as much infrastructure. So for example we avoid the language of stacks. On the other hand, we offer a coordinate-free definition of "formal group" directly suggested by c ©0000 (copyright holder)


Purpose: To evaluate inherent MTF(f), NPS(f) and DQE(f) of a prototype x‐ray imagingsystem with photon counting microchannel plate (MCP) detector.Method and Materials: The MCP detector was used in edge illumination mode as a linear array x‐ray detector in scanning slit image acquisition geometry. The detector FOV was 60 mm. MCPs with 63 mm length, 25 μm channel diameter and 5 μm channel wall thickness were used. The slit width was 0.25 mm. Delay line position encodingelectronics was used. Images were acquired using an x‐ray tube with 0.4 mm nominal focal spot size at 40 and 90 kVp using an SID of 50 cm and a magnification 1.1. MTF was measured using edge spread function method. NPS was calculated using flat field corrected flood images. DQE was calculated from MTF, NPS and using both measured and Monte Carlo calculated QE. Results: For 25 μm channel MCP, 50% MTF was achieved at 6 lp/mm and 4 lp/mm for 40 and 90 kVp tube voltages, respectively. The highest visualized frequency was 11 lp/mm at 40 kVp. NPS was shown to be frequency independent. QE measured at 90 kVp was 56% and 70% for 25 μm and 5 μm channel MCPs, respectively. Calculated QE was 64%, 86% and 92% for 25, 5 and 2 μm channel MCPs, at 90 kVp. The above QE values represent the DQE(0). The MTF(f) curves normalized by QE represent DQE(f) due to frequency independent nature of the NPS. Conclusion: MCP detector has shown adequate MTF(f) and DQE(f) for potential application in medical imaging. This is in addition to its inherently high count rate and scatter rejection feature of the scanning slit system. Combination of these capabilities in the photon countingsystem would allow for significant decrease in patient dose.


Tata modeling has great significance in software development. To know the quality of data modeling, we need to begin with the data model which is the product of the data modeling. Our analysis shows that there are deficiencies in current financial data model. Today's business dada model only shows the assets amount the enterprise holds and the proprietorship of the stockholders, this framework had built on the traditional accounting system which is regarded as golden rule in the commerce. And it could not show the risks of enterprises' operating. With this problem in mind we have established a new data model in concept level to reconstruct the conceptual schema of business database aimed at forecasting and disclosing future information of enterprise's operating. We added a special information, namely risk information, into the present data model, thus we built up a novel data model we call it "risk-oriented financial data model" (ROFD). This paper gives out the implement of the ROFD model. In this part of work we firstly presents the new ROFD model structure; secondly we identify the risk category and its relationships with others; thirdly introduce the temporal analysis method in our modeling and finally we illustrate the implement of usage of the ROFD model from accounting view. The risk-oriented financial conceptual data model has an advantage of providing the information about the risk of an enterprise to the users.

PURPOSE
To determine the frequency and socio-demographic/clinical correlates of insomnia in patients with chronic hepatitis B, hepatitis B virus (HBV)-related liver failure, and cirrhosis.

DESIGN AND METHODS
Up to 120 patients with HBV-related diseases and 40 matched healthy controls were recruited. Depressive and anxiety symptoms, early, middle, and late insomnia were measured.

FINDINGS
The frequency of ≥1 type of insomnia was 64.2% in patients and 35.0% in controls; frequencies of early, middle, and late insomnia in patients were 39.2%, 42.5%, and 48.3%, respectively, compared to 22.5%, 10.0%, and 25.0% in controls. Urban residency was independently associated with less insomnia of any type, accounting for 22.6% of the variance.

PRACTICE IMPLICATIONS
A considerable proportion of patients with HBV-related diseases suffer from insomnia that warrants more attention in clinical practice.


Sweet potato (SP) curd prepared by co-fermenting boiled β -carotene rich SP puree, cow's milk with curd culture, was evaluated for consumer acceptability of sensory attributes. One hundred consumers from the Orissa State, India evaluated SP curd in terms of five major sensory attributes, i.e., sweetness, color, texture, aroma and general appearance on a 9-point hedonic scale. The responses were modeled through binary logistic regression to understand the sensory attributes, which govern the decision process. Color and texture were found to influence consumer acceptability. The β -carotene supplied by SP-enriched yellow color of the curd, and starch and dietary fiber enhanced the thickness of SP curd.

PRACTICAL APPLICATIONS

Vitamin A Deficiency (VAD) is a serious problem affecting bulk of the disadvantaged population living in the developing countries. Fortification of foods with β-carotene (precursor of vitamin A) is widely regarded as a strategy to combat VAD through natural means. Sweet potato (SP) is a secondary staple food for small and tribal farmers particularly during off-season when there is a scarcity of food grains. Curd is a popular fermented dairy product, consumed widely in the Indian subcontinent. Fortifying curd with β-carotene rich SP can enhance the nutrient content (β-carotene, minerals, etc.) as well as culinary qualities (color and texture). Besides, modeling consumer preferences help us to identify the attributes, which govern the acceptability of SP curd. Such model could be compared with the sensory panel results to understand the accuracy with which decisions are made at the laboratory level.


This study developed Islamic Sex Education (ISE) interactive courseware to help users particularly parents discover guidelines in guiding them for sex education in Islam. In fact, sex education in Islam provides guidelines in manners related to what is allowed and forbidden, and stresses the faith towards the religion. Islam believes that parents play the main role to educate their children about this matter. However, the deficiency of this 'taboo' learning material in conveying the information makes the situation more stressful. In consequence, this study proposed the courseware as an attempt to the problem. We have conducted two evaluations namely; learning and reaction evaluation towards the effectiveness of the prototype with 41 respondents, which are parents. Employing the pre and post test, learning evaluation that includes 15 similar questions about ISE was given before and after the respondents used the courseware prototype. Meanwhile, the reaction evaluation was given after the respondents used the courseware prototype in assessing the overall effectiveness of the prototype. After analyzing the data, we found that the correct answers of the learning evaluation were increased after the respondents used the prototype; and overall they agreed the effectiveness of the prototype in increasing their knowledge.


Series-connection of SiC mosfets is an attractive solution to build cost effective and high efficiency medium voltage converters, however, the unequal voltage sharing among the power devices and the induced high dv/dt problems should be considered carefully. In this article, an active clamping topology and corresponding dv/dt control method for series-connected SiC mosfets are proposed. With the proposed topology, the drain-source voltage of each SiC mosfet can be clamped by discrete clamping capacitor, resulting in high robust switching. Besides, the clamping capacitor voltages can be autobalanced during the topology operation, so the peak voltages of the series-connected SiC mosfets can be easily balanced. By simply adjusting the gate drive delay time, the proposed topology could reduce the equivalent dv/dt of the device string with very small increase in power loss, so the high dv/dt induced switching noise can be suppressed greatly. Finally, a 4.8 kV/10 A half-bridge prototype is established with six SiC mosfets connected in series within per bridge arm, experimental results are provided to show the effectiveness and advancement of the proposed method.


The research work of Japanese scientist So Kawaguchi at the Australian Antarctic Division on the life and habits of krill is discussed. So Kawaguchi and his team have significantly advanced scientific knowledge about krill biology and behaviour, and contributed to the practical and sustainable management of the Southern Ocean krill fishery through the Commission for the Conservation of Antarctic Marine Living Resources (CCAMLR). A recent success was to get wild Antarctic krill (Euphausia superba) to school in captivity - something that has never been achieved before.


Simply stated, the international children's rights movement asks individual governments to take children's interests seriously when enacting laws for them. In order to enact policies that take children's interests seriously, all laws must be evaluated and examined from the child's point of view. An examination of the current international children's rights movement from the child's point of view, however, reveals considerable schisms between international principles and the state of the world's children. Professor Van Bueren directly examines the complex issues involved in defining and understanding children's rights. Her analysis of formal international law relating to the rights of the child is invaluable and would stand on its own. The text, however, does more than meticulously detail the rights of children in international law as enshrined in U.N. documents. Van Bueren also explores how other international fora and different countries are struggling with children's rights, both in theory and in practice. The International Law on the Rights of the Child is a text of mammoth proportions, containing fourteen well researched chapters. The first three chapters are devoted to examining the international children's movement 1' and defining the place of children in international law, both in terms of legal definitions of children 2 and in terms of children's rights and their relation to the rights of other family members."i The middle chapters explore children's substantive rights. 4 The last chapter documents organizations and treaty implementing bodies that have taken it upon themselves to ensure children's rights. GERALDINE VAN BUEREN, THE INTERNATIONAL LAW ON THE RIGHTS OF THE CHILD Reviewed by Roger J.R. Levesque* A great deal of ambition and optimism characterizes the current international children's rights movement. The sentiments are well justified; nothing short of a revolution is taking place. A prominent sign of this revolution is the almost universal ratification of the United Nations Convention on the Rights of the Child.' This Convention recognizes and seeks to ensure a series of substantive and procedural rights, making it the most comprehensive United Nations human rights treaty in force.2 In addition to enumerating the entire range of civil, political, economic, psychological, social, and cultural rights of children, the Convention proposes a series of important, perhaps even radical, guiding principles. When nations design and implement policies affecting children and their families, they now must consider the children's best interests,' take into account individual children's evolving capacities,4 and respect and ensure the inherent dignity of all children.5 * Assistant Professor of Criminal Justice, Indiana University, J.D., Columbia School of Law, 1993; Ph.D., University of Chicago, 1990.

REv. 959, 997 (1994) [hereinafter Implementing Children's THE RIGHTS OF THE CHILD These developments are truly remarkable and momentous. They essentially make one demand. Simply stated, the international children's rights movement asks individual governments to take children's interests seriously when enacting laws for them. In order to enact policies that take children's interests seriously, all laws must be evaluated and examined from the child's point of view.6 An examination of the current international children's rights movement from the child's point of view, however, reveals considerable schisms between international principles and the state of the world's children.' Indeed, in several instances, children are in much greater peril than they were before the children's rights movement blossomed.' The gap between rhetoric and reality illustrates the need to move beyond examining broad legal mandates and lofty principles. This discrepancy forces each nation to examine their existing laws and to focus their energies on implementing children's rights in a manner that truly protects children's interests. If the proper standard to evaluate the international children's rights movement is the extent to which it encourages countries to take children's interests seriously and the extent to which it provides an adequate guide for reform, then a text examining international law should be evaluated by a similar stanHuman Rights].

More specifically, a text examining children's rights in international law should detail existing international principles, should document the disparity between current law and international standards, should address needed reforms, and should never lose sight of the reality of children's situations. While there are several texts examining children's rights,9 only Professor Van Bueren's The International Law on the Rights of the Child'° has attempted this complex task. Given the challenges facing such an endeavor, Professor Van Bueren's text is simply exceptional.

These notes have been compiled from teaching materials developed by John Hayes between 1980 and 1995. Since their goals are to introduce basic concepts and practices, they are not grossly outdated in spite of their antiquity. Where necessary or desirable, minimal revisions indicate more recent data and practices. The sections include: Practice and Principles of Isotopic Measurements in Organic Geochemistry. This review originally appeared as pp. 5-1 to 5-31 in W. G. Meinschein (ed.) Organic Geochemistry of Contemporaneous and Ancient Sediments, a volume published in 1983 by the Great Lakes Section of the Society of Economic Pale-ontologists and Mineralogists. That book was intended to provide the notes for a short course offered in connection with the 1983 National Meeting of the Geological Society of America, but the short course drew inadequate enrollment and was cancelled. The original document included the introduction and sections 1 and 2 reprinted here, as well as an earlier version of section 3. Primary Standards of Stable Isotopic Abundances. Presented here as section 3, this material was revised and expanded frequently in the years after 1983, notably for use in a short course sponsored by Finnigan MAT in Beijing in 1986 and for frequent use in subsequent classes at Indiana University. Limits on the Precision of Mass Spectrometric Measurements of Isotope Ratios. Originally prepared for class use some time in the 1980s, this text (Section 4) explains how shot noise, or " ion-beam noise, " or " ion statistics " fundamentally limit the precision that can be attained in any measurement based on integration of an electrical current. Uncertainties in Blank-Corrected Isotopic Analyses. These notes (Section 5) were prepared for use by workers in the Biogeochemical Laboratories at Indiana University during the 1980's (accordingly, their presentation is far from " publishable "). They deal with the common problem in which an analytical result reflects the composition of a sample and, in addition, the magnitude and isotopic composition of an analytical blank.

depression of freezing point 0,828°C and pH 7,5(n=75) Various types of the blood cell of normal crawfish were counted and the results obtained were compared with those of crawfish immunized with goat's serum. But no definitive relationship was observed between the hemogram of normal crawfish and that of immunized crawfish. Another approach seems to have been suggested to a further study of the immunological character of crawfish.


This study aims to analyze the characteristics of the combustion of a mixture of rubber seed oil with methanol using droplets. The observed characteristics are flame temperature, ignition delay time, combustion rate, and visualization (high heat and flame colour). The variation of the mixture used in this study was a mixture of rubber seed oil and methanol with mixed percentages of 0%, 10%, 20%, 30%, 40%, and 50%. The droplet tool used for research is a tool designed by the researcher. The results showed that the highest flame temperature value was found in the 0% mixture, 114oC, and the lowest was in the 50% mixture, namely 79.67ºC. The highest Ignition delay time value is in the 0% mixture, which is 3.33 s, and the lowest is at 50%, which is 2.21 s. The highest combustion rate value at 50% mixture is 0.517 mm2/s and the lowest at 0% is 0.317 mm2/s. The highest flame height in the 0% mixture was 42.6 mm, and the lowest at 50% was 23 mm

abstract:This article discusses the practice of "meditative walking" and the way in which it can form one's spirituality, particularly in terms of a deep interconnectedness between humanity and nature, such that it leads to specific ecological commitments and doctrines. To make this argument, this article explores first the practice of Christian pilgrimage, and then turns to reflection on the rock garden at Ryōanji in Kyoto, with the hope that the ways in which this rock garden, in particular, has been described and interpreted might suggest to Christians a fresh way of experiencing and reflected upon the practice of meditative walking.


Abstract About $450 billion were donated to U.S. nonprofits in 2019 according to the most recently available data (Giving USA Foundation 2020). However, despite the increases in charitable dollars, the share of households that donate has been declining: in 2000, 67 percent of American households donated to nonprofits, but in 2016, only 53 percent of American households donated (Indiana University Lilly Family School of Philanthropy 2019). This trend in decreasing share of U.S. households that donate to charitable causes pre-dates the passage of the 2017 Tax Cuts and Jobs Act (TCJA), but could be accelerated by the recent policy changes. TCJA significantly changed federal tax policy and these changes are expected to affect charitable giving (Brill and Choe 2018; Ricco 2018; Rooney et al. 2017). Nonprofit leaders, as well as policymakers, have been exploring additional policy proposals to offset the potential negative impact on charitable giving. This paper investigates the estimated effects of potential policy proposals on charitable giving, donor incidence rates, and Treasury revenue. This study used the Penn Wharton Budget Model (Penn 2019a, 2019b) to run microsimulations of the effects of five tax policy proposals on charitable giving dollars, the number of households that donate, and the forgone Treasury revenue. The five proposals included: a non-itemizer charitable deduction; a non-itemizer charitable deduction with a cap; a non-itemizer charitable deduction with a floor; an enhanced non-itemizer charitable deduction, which provides a higher value deduction for low- and middle-income households; and a non-itemizer non-refundable 25 percent charitable giving tax credit. Of the five policy options analyzed, providing a non-refundable 25% charitable giving tax credit to non-itemizers has the largest positive impact, increasing both the amount of charitable giving dollars ($37 billion in 2018 dollars) and the number of donor households (10.6 million) of the five policy options analyzed. However, it is also the most "expensive" proposal (measured in terms of forgone Treasury revenue) for United States (U.S.) Treasury revenue (−$33.0 billion). Four of the five policy proposals bring in more charitable dollars than are lost in Treasury revenue. Four of the five policy proposals bring in more charitable dollars than were projected to have been lost as a result of TCJA. All five proposals bring in more donor households that were expected to be lost as a result of TCJA. This paper is based on a published report written and researched by [school] in partnership with the Wharton School of Business at the University of Pennsylvania and commissioned by Independent Sector.

It is feasible when haematocrit is greater than 35% or when it can be increased with increased doses of r-HuEPO, suggesting a reasonable response to the drug. It may not be feasible in patients with haematocrit below 30%, due to previously documented r-HuEPO unresponsiveness. It can be considered for every potential kidney transplant recipient planning to have elective surgery, in an effort to eliminate alloimmunization caused by homologous blood transfusion.


Edge detecting is the most important pre-processing in image analysis, feature extraction and recognition. Gradient is a basilic measure of edge images, and we can calculate the values of magnitude and rotation of edges with it. We analyse the first-order difference detectors first, such as Robert, Prewitt and Sobel detectors, then we analyse the Laplacian detector, that is a second-order difference one. A generalize mask is found based on the relationship of the classical edge detectors, and different value of its parameter is correspond to the detectors. The experiment show that the edges detected with the generalize mask are same to those detected with classical detectors, so the mask is reasonable.


We conducted in-situ high-pressure synchrotron x-ray diffraction (XRD) and electrical transport measurements on Dirac-like semimetal PdSn4 in diamond anvil cells with quasi-hydrostatic pressure condition up to 44.5 GPa–52.0 GPa. The XRD data show that the ambient orthorhombic phase (Ccca) is stable with pressures to 44.5 GPa, and the lattice parameters and unit-cell volume decrease monotonously upon compression. The temperature dependence of the resistance exhibits a metallic conduction and follows a Fermi-liquid behavior below 50 K, both of which keep unchanged upon compression to 52.0 GPa. The magnetoresistance curve at 5 K maintains a linear feature in a magnetic field range of 2.5 T–7 T with increasing pressure to 20.0 GPa. Our results may provide pressure-transport constraints on the robustness of the Dirac fermions.

We report the discovery of a novel class of compounds that function as dual inhibitors of the enzymes neutral sphingomyelinase-2 (nSMase2) and acetylcholinesterase (AChE). Inhibition of these enzymes provides a unique strategy to suppress the propagation of tau pathology in the treatment of Alzheimer's disease (AD). We describe the key SAR elements that affect relative nSMase2 and/or AChE inhibitor effects and potency, in addition to the identification of two analogs that suppress the release of tau-bearing exosomes in vitro and in vivo. Identification of these novel dual nSMase2/AChE inhibitors represents a new therapeutic approach to AD and has the potential to lead to the development of truly disease-modifying therapeutics.

The utility model discloses a distributive optical fiber flow rate meter and a measuring method thereof. A plurality of flow field pipelines to be measured are connected by one sensing optical fiber, one obstacle is respectively arranged in each flow field, and two rows of regular parallel vortexes in opposite rotation directions are formed after the fluid meets the obstacles, and the vortexes are called as Karman vortex streets. The vortex frequency is in proportion to the flow rate. The demodulation of the product is based on the interference mechanism of a phi-optical time domain reflection meter, the sensor optical fiber is subjected to forced vibration under the vortex impact force effect, a backwards scattered optical signal phase generated in the sensing optical fiber is also modulated by the vibration, so the flow rate of the flow field can be worked out. The distributive optical fiber flow rate meter adopts non-electricity measurement, is safe and reliable and can realize real-time continuous distributive remote measurement, the flow rate of all fluid of the fluid field to be measured wound by the sensing optical fiber, i.e. the detectable optical sensor can be detected, and the distributive optical fiber flow rate meter has higher sensitivity and higher cost performance than other optical fiber flow rate meters.


The article analyzes David Albahari's editorial activities in literary magazines and focuses on his work in the journal Književna rec (The Literary Word), which has been published in Belgrade since 1972 as an organ of the Književna omladina Srbije (Literary Youth of Serbia). David Albahari was a member of the editorial board from the winter of 1977 to the summer of 1984. This is a time when the dominance of so-called reality prose in Serbian literature is coming to an end and a new generation of authors appear whose literature would later be called postmodern. Albahari was involved in the process as both a writer and an editor. In the Književna rec, in addition to the prose of young local authors, he also published translations of contemporary international prose and also devoted himself to rock'n'roll culture. The article outlines the context in which he pursued this activity and tries to reconstruct the poetic and cultural ideological picture of the epoch.


This paper has three related aims. First, it argues that there is a need for a carefully formulated and properly established body of field electron emission science. Second, it outlines what this body of science should include. Third, it reports on progress on putting this science into place.


In this work we study the use of a focus measure to improve the 3D reconstruction of low reflectivity microscopic samples using white light interference microscopy. Simulation and experimental results show the improved reconstruction.


: To recognize continued speech, it is necessary to segment the connected acoustic signal into phonetic units. In this paper, as a parameter to detect the steady state segments in continued speech, we propese a new magnitude distribution. The suggested parameter represents a change rate of the magnitude of speech signals. As comparing this distribution with the other in adjacent frame, the state of the frame can be distinguished between steady state and transient state.


A field experiment entitled "Effect of moisture conservation practices under limited irrigation on yield and economics of wheat (Triticum aestivum L.)" was conducted at Agronomy Farm, College of Agriculture, Nagpur during rabi season of 2019-20. The experiment was laid out in Factorial Randomized Block Design with 12 treatment combinations, replicated thrice. The treatments consisted of three irrigation levels [One irrigation at late jointing stage (I1), Two irrigations at crown root initiation (CRI) and flowering stages (I2) and Three irrigations at CRI, late jointing and flowering stages (I3)] combined with four moisture conservation practices [Control (M0), Mulching with wheat straw (M1), Mulching with weed biomass (M2) and Antitranspirant spray {Kaolin @ 5%} (M3)]. Application of three irrigations as well as wheat straw mulch at 30 DAS recorded significantly higher plant height, number of tillers hill-1, number of leaves plant-1, dry matter accumulation plant-1 and relative growth rate. Yield attributing character viz. length of earhead, number of grains earhead-1, grain weight plant-1 and test weight along with grain, straw and biological yield of wheat were significantly higher with application of three irrigations compared to its lower levels as well as with application of wheat straw mulch at 30 DAS over rest of the respective treatments. Gross monetary returns, net monetary returns and B:C ratio also recorded the same trend.

Extant research shows that CEO characteristics and moral preferences affect earnings management. This paper studies how investors infer CEOs' moral preferences from earnings management and how this perception – in conjunction with their own social and moral preferences – shapes their investment choices. We conduct two laboratory experiments simulating investment choices. Our results show that participants perceive a CEO to be more committed to honesty when they infer that the CEO engaged less in earnings management. For investment decisions, a one standard deviation increase in a CEO's perceived commitment to honesty compared to another CEO reduces the relevance of differences in the CEOs' claimed future returns by 40%. This effect is most prominent among investors with a proself value orientation. To prosocial investors, their own honesty values and those attributed to the CEO matter directly, while returns play a secondary role. Overall, perceived CEO honesty matters to different investors for distinct reasons.


This dissertation is divided into three chapters. In the first chapter the activation of hydrogen molecules by splitting between bifunctional sterical demanding Lewis acid and Lewis base compounds such as 1,6-bis(bis(perfluorophenyl)boryl) hexane and 1,3-bis (diphenylphosphino)propane was investigated. The low storage capacity using large substitution to improve sterical effect led us to explore the amine borane derivatives, which are explained in chapter two.
Due to the high storage capacity of hydrogen in aminoborane derivatives, the ionic liquid methylguanidinium borohydride (N3H8C)C+BH4- (m.p. -5 °C, ρ (20 °C) = 0.95 g/ml) is presented. Under both thermal and catalytic conditions it releases 9.0 wt % H2.
In the third section, ionic liquids based on methyl guanidinium cation with different anions such as tetrafluoroborate were developed. We replaced these anions with transition metal anions to investigate hydrogen bonding and catalytic activity of ionic liquids. The catalytic activity is investigated particularly with respect to the cyclization of CO2 and propylene oxide forming cyclic carbonates.


Electrical equipment and wiring methods appropriate for the environments found in dairy housing are
discussed. Proper grounding of systems and equipment and selection of overcurrent devices to facilitate fail-safe
electrical systems are presented. Methods to limit voltage drop to 5% from the facility power source to the end-use
equipment are offered. There are recommendations for locating equipment, wiring methods, and additional safety
switches for protection of equipment for facilitating service. Since many recommendations are general, there are
suggested references for further details on wiring and equipment selection.

The impact of particle size, size distribution, and silica loading influence film properties of UV-cured hybrid organic-inorganic thin coatings. Commercial silica organols of hexanediol diacrylate monomer (HDDA) containing different monodisperse silica nanospheres were mixed with a polyester tetraacrylate (PEA) to give coatings controlled particle size distribution and silica loading (O to 40%). Dynamic mechanical thermal analysis (DMTA) measurements showed that complex modulus (E * ) increased and loss tangent (tanδ) decreased with small particle size and high silica content, but the dynamic glass transition temperature (T q ) was unaffected by size and size distribution. In all cases, the properties of hybrid coatings were found superior to the pure organic coating.


Physical unclonable functions (PUFs) are security primitives that rely on random manufacturing variations. In comparison to secure non-volatile memory, PUFs offer the same functionality for storing a cryptographic key but with a lower cost. This makes them especially interesting for systems with limited resources. Deriving a reliable key from a noisy PUF requires an error correction code. In recent years, several works have suggested polar codes for PUFs pointing to security benefits of this code class. However, none of them provided a hardware implementation, which additionally has to match the low-cost nature of PUFs, i.e., very small area. Since polar decoders are more complex compared to other codes like algebraic codes used for PUFs, the practical applicability of polar codes remained uncertain. This work shows for the first time that polar code implementations are well suited for PUFs. Our polar decoder implementation, which is optimized for PUFs, shows a total area of only 4.2k µm2 in a 22nm technology.


This study attempted to identify and determine distribution of Leptospira spp. in environmental samples using 16S rRNA and rpoβ genes amplification. The samples were collected from high risk areas in Selangor, Malaysia. A total of 105 environmental samples consisting of soil and water were subjected to direct DNA extraction and PCR reaction. PCR products were analysed using gel electrophoresis and subjected to sequence analysis. Thirteen out of 105 (12.38%) samples were amplified for 16S rRNA with an expected amplicon size of 330 bp, while 50 out of 105 (47.62%) samples showed amplification using rpoβ primers, but were not of expected size. Of the 13 16S rRNA amplified samples, only 5 were identified as Leptospira in the gene sequence analysis and clustered under uncultured group via phylogenetic tree. This study showed the DNA-based approach using PCR and sequence analysis is able to detect the presence of Leptospira, although environmental samples may contain diverse microbial populations that may complicate the detection. Overall, the study suggested the importance of surveillance for Leptospira from environmental samples.


Today's electric distribution manager must deal with an array of fast-paced developments including newer and faster technologies, consolidations, and the emergence of the Internet as a powerful, wide-reaching resource. These changes make it vitally important that managers understand all of their options when establishing or expanding data networks.


The molecular structural features of several alumina supported molybdena and cobalt catalysts were studied by analysis of their Raman spectra. It was found that as the amount of cobalt added is increased, the external layer spectra show decreasing amounts of molybdenum which have not interacted with the cobalt, while the internal layer spectra show increasing amounts of cobalt which have not reacted with molybdenum (Co/sub 3/O/sub 4/). These spectral results show how Raman spectroscopy can be used to characterize supported molybdena catalysts. While additional research is necessary to more completely define the exact nature of these types of catalysts, certain aspects of the various structural theories for the catalysts are now supported by these Raman data. Since molybdena catalysts become sulfided while being used as hydrodesulfurization catalysts, the structural characterization of sulfided catalysts is, from a practical standpoint, more important. Studies of sulfided catalysts are now in progress.


The title azide-bridged dinuclear Schiff base zinc(II) complex [Zn2(C12H16N3O3)2- (μ1,1-N3)2] was prepared and characterized by elemental analysis, IR spectrum, and single-crystal X-ray diffraction. The crystal belongs to the monoclinic system, space group P21/n with a = 8.736(2), b = 14.850(3), c = 11.775(2) , β = 102.42(3)o, V = 1491.8(5) 3, Z = 2, Dc = 1.593 g/cm3, Mr = 715.36, λ(MoKα) = 0.71073 , μ = 1.669 mm-1, F(000) = 736, the final R = 0.0338 and wR = 0.0789. A total of 3411 unique reflections were collected, of which 2777 with I 2σ(I) were observed. The molecule of the complex is located on a crystallographic inversion centre. Each Zn atom in the complex is five-coordinated by one Schiff base ligand and two bridging azide groups, forming a trigonal bipyramidal configuration. The Zn···Zn distance is 3.328(2) . In the crystal structure, molecules are linked through intermolecular C–H···N hydrogen bonds, forming layers parallel to the bc plane. The complex shows low cytotoxic property to both normal and carcinoma cells.


Richard Ehrenborg conjectured that in a bipartite graph G with parts X and Y, the number of spanning trees is at most ∏ v∈V(G) deg(v) divided by |X | · |Y |. We make two main contributions. First, using techniques from spectral graph theory, we show that the conjecture holds for sufficiently dense graphs containing a cut vertex of degree 2. Second, using electrical network analysis, we show that the conjecture holds under the operation of removing an edge whose endpoints have sufficiently large degrees. Our other results are combinatorial proofs that the conjecture holds for graphs having |X | ≤ 2, for even cycles, and under the operation of connecting two graphs by a new edge. We also make two new conjectures based on empirical data, each of which is stronger than Ehrenborg's conjecture.


Factors that predicted the outcome of drug treatment (alprazolam or imipramine) of panic disorder were studied in a sample of 123 Scandinavian patients participating in a multicenter placebo‐controlled 8‐week trial. The attrition rate was 95% for alprazolam, 73% for imipramine and 46% for placebo. For the intention‐to‐treat and 3‐week‐completer samples, drugs and anxiety symptoms at baseline were the best predictors of improvement on the Global Improvement Scale and on symptom scales focusing on panic attacks, phobic behavior and anticipatory anxiety. For completers of the 8‐week trial, only baseline scores predicted outcome. Generally, more severe symptoms at baseline predicted a worse outcome. A subsample of patients had a marked placebo response. Avoidance, sex, age, childhood psychopathology and previous treatment experience had no or only a weak impact on the outcome. The relationship between panic disorder and mood disorder is presented elsewhere.


Regarding the importance of information, it is necessary to establish contingency plans to allow the organizations handle possible situations that attempt against the continuity of the business. In order to make it possible, it is necessary that the organizations identify the critical information for the development of their functions and activities and include specific policies and controls in order to handle this information. The study is framed within the type of exploratory investigation, using as instruments to collect information, field observation, observation to the facilities of the Central Archive and to the Center of Systems and Computers, the application of interviews, and attendance to the conferences given by the DPAE (Direction of Emergency Prevention and Attention in Bogota).


Current transients in radiation induced conductivity (RIC) of low-density polyethylene (LDPE) exposed to 17 ns bremsstrahlung pulses were studied. Three models of the RIC relaxation, to 30 /spl mu/s after the pulse, have been tested numerically. Strong influence of the measuring circuit on the experimental results was taken into consideration. Verification shows that the RIC relaxation immediately after the excitation consists of the combination of at least two exponential components with markedly different relaxation times. This supports our thesis, that the charge transport in LDPE during the 30 /spl mu/s period after the RIC excitation by means of bremsstrahlung is occurring in the conduction band as a shallow-trap-limited, nondispersive current.

The author's main interest is in folklore and the byways of history, and it is with these in view that he has hunted down many fascinating references to the days when the beaver, the wild boar, the wild cat and the wolf were living members of the fauna of England. Despite the title the book deals mainly with England, or rather Roman Britain north to the Antonine Wall, for the wild cat is still, of course, a most vigorous member of the fauna in the Scottish Highlands. The introduction deals also with some other creatures that are not lost beasts here, such as the reindeer and wild cattle, and even the great auk, which is not a beast. The author is also out of touch with modern Britain in not knowing that the pine marten still exists in England and the polecat in Wales he says it 'may be there still', but did not trouble to check with any modern book on British mammals. But if naturalists may have a few complaints, lovers of folklore and historical byways will have a most excellent read.

We examined the jaw size, age and sex distribution of 324 red deer constituting a comprehensive record of all recreational hunting kills made by a single hunter of the Tararua ranges of North Island New Zealand over a period 20 years (1976-1996). The proportion of stags shot at times other than the rut (March April) was not significantly different to that in a sample of deer obtained by commercial helicopter hunting and did not change significantly after the first three years of hunting regardless of any effect of helicopter hunting. Conversely, significantly greater numbers of males were shot during the months of the rut and this proportion increased significantly after the first three years of hunting presumably as a result of increased selectivity and or skill. The recreational hunter harvested significantly greater numbers of older animals than did helicopter hunters. The proportion of older animals shot during, and at times other than the rut, increased significantly after the first three years of hunting. Analysis of jaw length versus age showed a significant increase in the jaw size of age cohorts born after 1976 i. e. after an increase in culling effort and was indicative of a general decline in population density during the period of the study. __________________________________________________________________________________________________________________________________


Abstract Background: Nanoparticles have shown higher efficacy in delivering photosensitizers for photodynamic therapy (PDT). Here we reported the comparison of the killing effects of conventional photosensitizer Photosan-II and Photosan-II loaded hollow silica nanoparticles (HSNP) on Huh-7 human hepatoma cells. In addition, we explored the underlying mechanisms of the effects of Photosan-II loaded HSNP in the tumor microenvironment. Methods: Photosan-II was loaded into HSNP by one-step wet chemical-based synthetic route. The cellular viability was determined by MTT assay. Apoptotic and necrotic cells were measured by flow cytometry. Furthermore, Huh-7 xenograft model in nude mouse was established and PDT was administrated when tumor size was 2 mm3. Results: We found that Photosan-II loaded HSNP was more effective to inhibit the proliferation and induce the apoptosis of Huh-7 cells than free Photosan-II. In addition, Photosan-II loaded HSNP was more effective to inhibit the growth of Huh-7 xenograft in nude mice than free Photosan-II. Western blot analysis demonstrated that the expression levels of COX-2, NF-κB, ERK1 were significantly lower in the xenografts from mice treated with Photosan-II loaded HSNP than in those treated with free Photosan-II. Conclusions: Our data suggest that HSNP is a promising vehicle for photodynamic therapy that could increase the photodynamic efficacy of Photosan-II both in vivo and in vitro, and the downregulation of COX-2, NF-κB and ERK1 may account for the higher efficacy of Photosan-II loaded HSNP for hepatoma.


This paper examines the process of mergers and acquisitions from the combined perspectives of leadership and decision–making/moral hazards. In particular, we examine the roles and intentions of senior managers in M&A activities based on leadership theories, and then use this framework in evaluating the human resource impacts of mergers and acquisitions. Existing literature suggests disconnects between the espoused values and guiding principles of mergers and acquisitions with the actual impacts of these deals. More specifically, there are often clear gaps between pronouncements prior to M&A transactions and the subsequent reality in terms of financial returns, human resource impacts, market sh are effects, and industry realignment. This paper then applies this conceptual framework in reviewing two major M&A deals in differing industries. We also explore the moral hazard and decision traps of M&A transactions in regards to shareholder benefits, consumer benefits, and senior management compensation packages.


We describe a semi-analytical approach for modeling fibers which guide THz radiation in a porous core by the photonic bandgap effect due to a honeycomb cladding of air holes. These porous-core honeycomb bandgap THz fibers (PCHBTFs) are modeled as equivalent step-index fibers (SIFs). The effective core index of the SIFs can be solved analytically as that of the fundamental space-filling mode of the triangular lattice comprising the porous core. The cladding index is taken as that of the bandgap edge with the lower index and is computed numerically. The validity of the analogy between PCHBTFs with SIFs is established by comparing the mode profiles, mode number, mode indices, and the fraction of mode power in the core obtained for a 19-cell core multimode THz fiber by the semi-analytical theory with results by finite element method. The subtle difference in mode degeneracy of the PCHBTFs and SIFs is briefly discussed. The semi-analytical theory also predicts that a seven-cell core PCHBTF is effectively single mode with higher-order modes pushed close to the bandgap edge.


Abstract For premature babies, rapid and harmless early health status detection can both ensure survival and improve the quality of life. In this regard, the best method for detecting the health status is the least invasive process for the baby, using the principle of less contact, more observation. In the neonatal intensive care unit, the important factors in keeping neonates alive and reducing their sequelae are the preliminary diagnoses and follow-up systems that are created using development technology. Hyperspectral imaging is considered a powerful tool to determine the health status of neonates because it provides diagnostic information on the disease. In this study, deep convolutional neural network models using hyperspectral imaging in the visible and infrared regions (204 bands at 400–1000 nm) were used to detect the health status of neonates. Hyperspectral images were taken in a one-month period from different neonates at Selcuk University, Faculty of Medicine, neonatal intensive care unit (Konya, Turkey), and 6528 images (3264 unhealthy, 3264 healthy) in total. Data augmentation methods, such as rotation, flipping, shearing, zooming, shifting and brightness enhancement, were applied to the hyperspectral images for the training of the convolutional neural network model. By using all spectral bands, the number of 6528 images obtained from neonates in the neonatal intensive care unit was augmented to 65280 images. The final results were accuracy of 93.38%, kappa coefficient of 86.76%, specificity of 92.77% and sensitivity of 93.98% for the 65280 hyperspectral images employed. In this study, the objective was to determine the noninvasive health status of neonates with convolutional neural networks using visible and infrared spectral bands. The results show that hyperspectral imaging operating in the visible and infrared regions and the convolutional neural network are highly effective in detecting the health status of neonates.


The interrelation between fuzzy logic and cluster renewal approaches for heat transfer modeling in a circulating fluidized bed (CFB) has been established based on a local furnace data. The furnace data have been measured in a 1296 t/h CFB boiler with low level of flue gas recirculation. In the present study, the bed temperature and suspension density were treated as experimental variables along the furnace height. The measured bed temperature and suspension density were varied in the range of 1131–1156 K and 1.93–6.32 kg/m, respectively. Using the heat transfer coefficient for commercial CFB combustor, two empirical heat transfer correlation were developed in terms of important operating parameters including bed temperature and also suspension density. The fuzzy logic results were found to be in good agreement with the corresponding experimental heat transfer data obtained based on cluster renewal approach. The predicted bed-to-wall heat transfer coefficient covered a range of 109–241 W/(mK) and 111– 240 W/(mK), for fuzzy logic and cluster renewal approach respectively. The divergence in calculated heat flux recovery along the furnace height between fuzzy logic and cluster renewal approach did not exceeded ±2%. ∗Corresponding Author. E-mail: email@example.com 92 A.

Sickle cell disease (SCD) is among the most common inherited hematologic diseases in sub‐Saharan Africa (SSA). Historically, hydroxyurea administration in SSA has been restricted due to limited region‐specific evidence for safety and efficacy.


This randomized controlled trial was designed to determine the safety and efficacy of laparoscopic donor nephrectomy (LDN) in comparison with short‐incision open donor nephrectomy (ODN).


In this paper, the classical Schrodinger equation (CSE), which allows the study of classical dynamics in terms of wave functions, is analyzed theoretically and numerically. First, departing from classical (Newtonian) mechanics, and assuming an additional single-valued condition for the Hamilton's principal function, the CSE is obtained. This additional assumption implies inherent non-classical features on the description of the dynamics obtained from the CSE: the trajectories do not cross in the configuration space. Second, departing from Bohmian mechanics and invoking the quantum-to-classical transition, the CSE is obtained in a natural way for the center of mass of a quantum system with a large number of identical particles. This quantum development imposes the condition of dealing with a narrow wave packet, which implicitly avoids the non-classical features mentioned above. We illustrate all the above points with numerical simulations of the classical and quantum Schrodinger equations for different systems.


Discrete mathematics is an important course of computer science and its correlative specialties.This paper deals with how to improve the undergraduates' ability of mathematics thought and application in the teaching of discrete mathematics from different point of view,such as the content selected and the way of teaching.


This paper investigates a wireless-powered communication network (WPCN) setup with one multi- antenna access point (AP) and one single-antenna source. It is assumed that the AP is connected to an external power supply, while the source does not have an embedded energy supply. But the source could harvest energy from radio frequency (RF) signals sent by the AP and store it for future information transmission. We develop a discrete time-switching (DTS) protocol for the considered WPCN. In the proposed protocol, either energy harvesting (EH) or information transmission (IT) operation is performed during each transmission block. Specifically, based on the channel state information (CSI) between source and AP, the source can determine the minimum energy required for an outage-free IT operation. If the residual energy of the source is sufficient, the source will start the IT phase. Otherwise, EH phase is invoked and the source accumulates the harvested energy. To characterize the performance of the proposed protocol, we adopt a discrete Markov chain (MC) to model the energy accumulation process at the source battery. A closed-form expression for the average throughput of the DTS protocol is derived. Numerical results validate our theoretical analysis and show that the proposed DTS protocol considerably outperforms the existing harvest-then-transmit protocol when the battery capacity at the source is large.


The COVID-19 pandemic challenged the public health sector and has impacted various sectors such as politics, education, economy, and socio-culture. As of 24 July 2021, there have been 3,127,826 confirmed cases of COVID-19 in Indonesia. Large-scale social restrictions, stay at home, online learning, and work from home have led people to change their ways of life. These may increase the duration and the need to use the gadget and may lead to addiction. We conduct a webinar to increase public knowledge and awareness regarding gadget addiction during the COVID-19 pandemic as a means to maintain general well-being. This study examines webinar participants' knowledge before and after the webinar. The participants were asked to fill a pre-test and a post-test. Thus the results were statistically examined to determine the knowledge difference before and after the webinar. The demographic data shows the webinar participants were dominated by female participants, people aged 17-25 years old, and high school graduates. The participants that are included in this study are 265. There is an increase and significant difference (p<0.05) between pre and post-test scores evaluated by Wilcoxon signed-rank test. The number of participants with low-level knowledge is reduced from 52 to 42 after the webinar. In conclusion, there is an increase in knowledge about gadget addiction in the era of the COVID-19 pandemic after the webinar based on the pre-test and post-test data. Thus, education through a webinar can be applied to increase the knowledge regarding gadget addiction during the COVID-19 pandemic.

Introduction: Aging process is a natural phenomenon in which changes social and moral-spiritual life in elderly. Such changes may result in poor self-acceptance which ends in severe depression. This research analyzed how reminiscence therapy influence elderly's self-acceptance with the approach of gerotranscendence theory. Method: This study used quasy experiment with pretest-posttest non randomized control group design. The sampling technique was used purposive sampling. Twenty eight samples in Jombang UPT PSLU in Kediri divided into two groups, 14 samples in experiment group and 14 samples in control group, and samples from Elderly's Health Center of Puhjarak Public Health Center also. The independent variables in this study were elderly's self-acceptance and the dependent variable was the reminiscence therapy. Result: The results showed that the treatment group in UPT PSLU, there was an increasing acceptance of elderly during the pretest and posttest. The value of self-acceptance pretest between treatment and control group showed p=0,139, and posttest between treatment and control group showed that p=0,000. Treatment group in Elderly's Health Center, showed that elderly's self-acceptance increased during the pretest and posttest with p = 0.001. The value of self-acceptance pretest betwen treatment and control group showed p=0,226, and posttest between treatment and control group showed p= 0.000. The difference posttest values of inter-treatment group of UPT PSLU and Elderly's Health Center showed that p=0,854 and p=0,017 from inter-control group. Discussion: The reminiscence therapy has a great effect in increasing self-acceptance of elderly people. However, in addition to this therapy, age, the duration of living in convalescent and nursing home for the elderly, pleasant surroundings, and social supports were also contributing factors. Suggestions for further research are expected to perform strict control of observing respondents and locations of the research so as to maximize the result

Most of them had no proper methods of clean-keeping. The result of monitoring of 22524 dietetic utensils showed that 3307 of all were positive of coliformgrop, and the bad qualified rate was 85. 32 %. It was suggested that should be strengthemed the hygienic management of dietetic utensils sterilization.


Condition monitoring and fault diagnosis of rolling element bearings (REBs) are at present very important to ensure the reliability of rotating machinery. This paper presents a new pattern classification approach for bearings diagnostics, which combines Mathematical Morphology (MM) and Multi-output Adaptive Neuro Fuzzy Inference System (M-ANFIS) classifier. MM is used for filtering Vibration signals, which acquired through the accelerometers mounted on the bearing housing. In this regard, to have an effective morphological operator, the structure elements (SEs) are selected based on the Kurtosis value. Then, to design an automated fault diagnosis structure, the features of this filtered signal, are extracted and used in the M-ANFIS model to learn and classify the bearing condition. The MM method overcomes the drawbacks of other signal processing methods and the M-ANFIS model can handle variation conditions. The experimental results indicate that the proposed strategy not only reduces the error rate but also is robust to changes of load, speed and size of defects.


Redundant parallel manipulators have some advantages over the nonredundant parallel manipulators. It is important to determine how many additional branches should be introduced. This paper studies whether one or two additional branches should be added to a 3-DOF parallel manipulator by comparing the flexible deformation of a 3-DOF parallel manipulator with one additional branch and that with two additional branches. The kinematic and dynamic models of the redundant parallel manipulator are derived and the flexible deformation is investigated. The flexible deformation of the manipulators with one additional branch and two branches is simulated and compared. This paper is helpful for designers to design a redundantly actuated parallel manipulator.


Methodological aspects of the high-resolution dilatometry analysis of the reverse α→γ-transformation in cold-worked metastable austenitic steel Fe-0.07C-18.7Cr-9.2Ni-0.6Ti-1.1Mn-0.4Si (wt.%) were considered. It was shown that the reverse α→γ-transformation occurs in the temperature range from AS=520 °C to AF=920 °C. Two consecutive stages corresponding to shear and diffusion transformations were revealed. An abnormal increase in the sample length of the program steel during the reverse α→γ-transformation was found. The recrystallization process also developed during austenitization and was accompanied by a decrease in length of the specimen.


Objectives: We aim to investigate the involvement of the choroid and retinal nerve fiber layer (RNFL) in COVID-19 patients using spectral domain optical coherence tomography. Methods: This cross-sectional study was conducted between April and June 2020. 40 patients (23 female and 17 male) with COVID-19 and 42 healthy individuals (26 female and 16 male) were included in the study. The OCT scans were performed 4 weeks after the COVID-19 diagnosis. Results: In the COVID-19 group, in the right eyes, the mean nasal choroidal thickness was 295.70 ± 7,046 μm (p = 0.017), mean subfoveal choroidal thickness was 333.25 ± 6,353 μm (p = 0.003), mean temporal choroidal thickness was 296.63 ± 6,324 μm (p = 0.039), and mean RNFL was 89.23 ± 1.30 μm (p = 0.227). In the left eyes, mean nasal choroidal thickness was 287.88 ± 9,033 μm (p = 0.267), mean subfoveal choroidal thickness was 333.80 ± 9,457 μm (p = 0.013), mean temporal choroidal thickness was 298.50 ± 9,158 μm (p = 0.079), and mean RNFL was 89.48 ± 1,289 μm (p = 0.092). Compared with the control group, the patient group had significant thickening of the choroidal thickness in all quadrants of the right eyes, and significant thickening of the subfoveal choroidal thickness in the left eyes. There was no significant difference in the RNFL thickness between groups (p > 0.05). Conclusion: COVID-19 may cause a subclinical involvement in the choroidal layer.


Background. Enzymes that play a major role in folate metabolism are 5,10-methylenetetrahydrofolate reductase (MTHFR), thymidilate synthase (TS), methionine synthase (MS) and methionine synthase reductase (MTRR). Polymorphisms in their corresponding genes alter their enzymatic activity. The aim of this study was to determine the frequencies of polymorphic MTHFR and TS genotypes in healthy adults from Slovenian population in order to estimate the proportion of individuals that may be at risk for certain diseases or increased toxicity if treated with antifolate drugs. Methods. MTHFR and TS polymorphisms were studied by a genotyping technique, based on polymerase chain reaction (PCR) followed by restriction enzyme analysis. DNA samples from 122 unrelated adult healthy subjects were obtained from the Tissue Typing Center and University Children's Hospital in Ljubljana. Results. In the analyzed group 62.3% of individuals carried at least one polymorphic MTHFR 677T allele and 52.5% carried at least one polymorphic 1298C allele. Only 12% of individuals had no polymorphic MTHFR allele. The frequencies of MTHFR genotypes were influenced by the age of the subjects under investigation. The frequency of the TS 3R/3R genotype in Slovenian population was significantly lower than in some other populations. Conclusions. Genetic polymorphisms in folate metabolic pathway occur with high frequency in Slovenian population and modify cancer risk. Regarding the influence of these polymorphisms on the efficacy of treatment with antifolate drugs the introduced genotyping method could contribute to the individualization of treatment with methotrexate and 5-fluorouracil.


This paper explores the reasons for emergence and the features of
ambient media in an urban socio-cultural space. Global socio-cultural changes in
the contemporary world lead to informational oversaturation, trauma-generating
factors and, as a consequence, search for new adaptive mechanisms for an
individual to accept the social reality. Ambient media become an unobtrusive
advertising communication built into the environment and people's daily practices
in the contemporary society.
To analyze ambient media as a new form of communication, the authors applied
the method of structural and functional analysis and a systemic approach.
The paper argues that ambient media are a breakthrough, new and comparatively
young advertising communication disproving traditional views of advertisement
types, methods and forms. This is a communication offering innovative patterns of
interaction with the consumer and the environment and changing individuals' notions
of a socio-cultural space where they exist.
The authors identified the main features of ambient media, as well as the human
trauma symptoms that can be caused by communication processes in the
contemporary society:
It is demonstrated that ambient media as a new type of communication are in all
respects integrated into the urban space of European countries and the USA. For
contemporary Russia, however, ambient media as a type of communication are a
new trend in the socio-cultural space of Russian cities.


An ab intio two-body analytical potential function was constructed to describe Mn(II)-water interactions. Classical Monte Carlo (MC) and molecular dynamics (MD) simulations have been performed to study the hydration structure of Mn(II). The study was extended to a combined QM/MM-MD level in order to investigate the influence of higher (n-body) terms. The structure of the hydrated ion is discussed in terms of radial distribution functions, coordination numbers, and angular distributions. The results of the QM/MM-MD simulations have been found to be much closer to the experimental values, proving that many-body effects play an important role in the description of the hydrated Mn(II) ion.


Resistance training alongside proper protein intake is an important tool to mitigate the deleterious effects of the aging process on skeletal muscle tissue. However, it is not completely elucidated whether adding protein supplementation provides further improvements on body composition outcomes of older adults during resistance training programs. The present narrative review aimed to describe the most recent evidence regarding the effects of protein supplementation on both lean body mass and fat mass of older adults and to provide insight into how health professionals may use this information to properly design nutritional programs for this population. While individuals with previous training experience, not meeting daily protein requirement, or displaying frailty symptoms may experience some benefits, protein supplementation does not seem to provide further improvements in untrained and healthy subjects. Aspects such as the age of the individuals and the different characteristics of the supplementation protocols must be considered when making evidence-based decisions regarding this topic.


This article provides an outline of the basic organizational structure of the oil industry in south-eastern Poland in the years 1944–1989 from the perspective of national levels of management and the conditions of the Polish People's Republic. The paper begins with an exploration of the current state of research, describing the previous principles of functioning of the industry in Galician times and the period of the Second Republic of Poland. Particular attention is given to the transformation to the socialist model of oil industry management after WWII, its national and territorial organization, and the functioning of branches of central institutions in companies located in the territory of the contemporary Podkarpacie. The paper then examines changes to the organizational structure of local extraction plants and refineries. In conclusion, the article states that frequent and poorly justified (at least financially) structural changes demonstrate a lack of comprehensive and long-term of management of this branch of economy in the economic plans of People's Poland.


Objectives: Student assessment is one of the vital elements in educational process. It is essential to conserve the formative nature of the assessment so that assessment is more structured and meaningful. Hence, it is necessary to review the existing formative assessment practises. The study was undertaken with purpose to estimate and compare the student and faculty perception about formative assessment examination in the institution. Materials and Methods: Seventy students and four faculties were enrolled for study on the basis of voluntary participation. The study participants were subjected to open and close-ended questionnaire, focus group discussions and individual interviews to obtain the perception. The responses were analysed by descriptive and thematic analysis. Results: Overall, the participants found the formative assessment practises to be satisfactory with few exceptions as there should be uniform judging criteria, and the feedback mechanism be more structured. Faculty mentioned that higher cognitive domain should also be tested in formative assessment. Conclusion: The study has brought forward the need for the sensitization of students so that applicability of formative assessment is enhanced. The periodic feedback should be obtained from faculty and students; the input will aid to plan strategies to maximize the student learning.


Abstract Narciclasine (NCS), an Amaryllidaceae alkaloid from Narcissus tazetta bulbs, is a potent plant growth inhibitor. It shows a broad range of inhibitory effects on seed germination and seedling growth in wheat (Triticum aestivum). In this study, the chlorophyll content of light‐grown wheat seedlings was markedly reduced in the presence of NCS. In etiolated wheat leaf sections, the greening process initiated upon illumination was inhibited by NCS. The block of chlorophyll accumulation in the presence of NCS was most probably due to the block of the formation of 5‐aminolevulinic acid, an essential chlorophyll precursor. Western blot analysis showed that the formation of light harvesting chlorophyll a/b binding protein (LHCII) was also inhibited by NCS. Electron microscopy studies provided direct observation that the formation of chloroplast and internal membrane systems were blocked when etioplasts were illuminated in the presence of NCS. Thus, our study showed that NCS inhibited chlorophyll and chloroplast protein accumulation, concomitantly chloroplast formation.


Participatory democracy is a basic theory of the system of administrative hearings,which provides a new perspective of the representation and the scope of the system of administrative hearings that promotes its development and reform.The construction of China's system of administrative hearings enhances the openness and transparency in decision-making,but there are still some defects,such as lack of openness,the narrow scope of application,lack of representation,inequalities between the government and members of the public.The improvement of the system of administrative hearings depends on the adjustment of the relationship between state and society,the vitality of news media that should be motivated and expanding the scope of the system of administrative hearings.


Flames in heated tubular channels, with radii on the order of the flame thickness, are investigated experimentally and numerically to understand the various effects of flame / wall interfacial heat transfer. First, combustion is studied in a burner-stabilized configuration, with an imposed temperature profile along the tube wall, to isolate and understand the role of flame / wall heat loss, without heat recirculation. The flames are found to be influenced by competition between energy required to preheat the reactants, heat released by combustion, and heat lost to the wall. To model such flames, an extension to the standard 1 – D, volumetric formulation is proposed which uses detailed chemistry, mixture-averaged transport, and an interfacial heat transfer sub-model. The interfacial heat transfer sub-model uses a non-linear, radially-varying heat source to account for combustion and captures enhanced interfacial heat transfer inside the reaction zone. The degree of heat loss in the reaction zone is found to be sensitive to non-linear heat release. Heat release, from chemical reactions, acts as a local thermal discontinuity resulting in steep temperature gradients and high heat loss. This is absent in present volumetric formulations and in standard interfacial heat transfer correlations; which do not account for chemical reactions and treat the flow as thermally fully-developed. The model is, then, validated with experiments. In the experiments, strongly burning, axisymmetric methane / air flames, stabilized inside the wall temperature profile, are found to be "flat" for sufficiently small tube dimensions. The extended model is also found to be in agreement with experimental results and gives improved quantitative predictions for flame stabilization position, compared to the standard volumetric approach. Temperature and species profiles are also compared to those obtained from a detailed multi-dimensional formulation; which is assumed to predict the actual structure of the flame. Again, the extended volumetric model shows significant improvement compared to the standard formulation. Deviations between the extended model and the detailed model are also investigated to determine the nature of the unconsidered multi-dimensional effects. Finally, propagation and extinction in a participating channel is modeled to understand the combined effects of flame / wall heat transfer and heat recirculation on burning rate. These phenomena are deemed to be the leading-order effects for this case. The interfacial heat transfer sub-model is reformulated to use a non-linear heat source, for combustion, and radial convection, for flow redirection. The model is evaluated for stoichiometric flames over a range of channel inlet flow velocities and confirms the existence of regimes for fast and slow flame propagation, which have non-monotonic variation for burning rate. Peak heat loss is also found to coincide with peak heat release, rather than the maximum temperature location. The numerical model is, once again, found to give improved…


1,2,3,4,5 Dept of Computer Science and Engineering, Sahyadri College of Engineering and Management, India ---------------------------------------------------------------------***--------------------------------------------------------------------Abstract Face recognition is the process of identifying one or more faces in images or video clips by analysing and comparing known patterns. One of the ways to do this is by comparing selected facial features from the image and a facial database. Algorithms typically extract facial features and compare them to a database to find the best match. This has wide range of applications which includes Security, Criminal Identification, Payments, Healthcare, Marketing and so on. There are plenty of algorithms devised and used for face recognition, each having its own benefits and shortcomings. For any face recognition algorithm, the two key stages are extraction of features and their classification. In this paper we focus on comparison between the performances of PCA, KPCA, KFA and LDA algorithms against AT&T, Yale and UMIST datasets.


Background. Sphingolipids such as sphingosine-1-phosphate (S-1-P) are potent extracellular mediators released in response to vessel injury. S-1-P binds to G-protein-coupled receptors, which can be either G αi or G αq linked. This study examines the signaling pathways involved in vascular smooth muscle cell migration after stimulation by S-1-P. We hypothesized that S-1-P stimulates migration of smooth muscle cells that is dependent upon a G αi -coupled receptor, ras, phosphoinositol 3-kinase (PI3-K), and ERK 1/2. Methods. Vascular smooth muscle cells were cultured in vitro. A linear wound assay and Boyden chamber assay of migration were employed in the presence of S-1-P and inhibitors of G αι [pertussis toxin (PTx), 100 ng/ml], G αq (GP-2A, 10 μM), ras [manumycin A (MA), 10 μM], PI3-K [Wortmannin (Wn), 10 μM], and MEK1 [PD98059 (PD), 25 μM]. Western blotting was performed separately to examine p42/p44 MAP kinase (ERK 1/2) activation in response to S-1-P with these inhibitors. Results. S-1-P induced vascular smooth muscle cell migration. This response was decreased by preincubation with PTx, suggesting a receptor linked, G αi -mediated response. Application of a G αq inhibitor did not affect this response. S-1-P induced ERK 1/2 phosphorylation in a time-dependent manner. This S-1-P-induced cell migration was PD-sensitive in the Boyden chamber assay, confirming that it is MEK1- and ERK1/ 2-dependent. Inhibition of ras with MA and PI3-K with Wn also reduced ERK phosphorylation and smooth muscle cell migration in response to S-1-P. Conclusion. S-1-P induces smooth muscle cell migration through a G αi -linked, ras- and PI3-K-coupled, ERK 1/2-dependent process. Understanding signal transduction will allow targeted molecular interventions to treat the response of a vessel to injury.
