Meaning exists on various levels, among them what is based upon knowledge and bound by linguistic and social consensus. Creativity can be achieved by a departure from normal usage through one of the following means: transferring a word into a fresh context, e.g. metaphorical usage; transferring sentence structure into a fresh context, e.g. making an indicative sentence express an imperative; relaxing the rules of meaning – the rules of inflection, morphology, usage of particles, sentence order and structure. The article employs numerous verses of the Qur'an to explain how departure from normal usage achieves excellence in the language and style of the text of the Qur'an.

Students' differences in culture and language predispose them to different communication practices and even different test-taking skills. In a culturally responsive classroom, effective teaching and learning occur in a culturally supported, learner-centered context, whereby the strengths students bring to school are identified, nurtured, and utilized to promote student achievement. This creates an environment of acceptance and respect for the students' ethnic background and fosters development of ethnic identity. The purpose of education is to enable learners of all demographics to participate successfully in the modem economy and society. It is essential that children are given the best educational experience possible based on sound educational theory and practice. This paper seeks to provide a framework within which teachers and schools can choose and plan experiences that they think children should have.


Global climate change alters the relationship between temperature and light in aquatic ecosystems, which is expected to affect the success of different phytoplankton species. To examine this, the interactions between temperature, photoperiod and light exposure (LE) (integral daily light supply) on specific growth rates were analysed for Limnothrix redekei, Planktothrix agardhii (cyanobacteria), Nitzschia acicularis and Stephanodiscus minutulus (diatoms). A model of factor interactions was developed based on new (P. agardhii and St. minutulus) and previously published laboratory studies. It describes the measured data with high precision. Temperature and photoperiod affect the parameters of the light-growth response curve differently, but these effects are the same for all species. The link between functions for temperature and photoperiod is more species-specific. Using meteorological data, the model developed here was used to study the interplay of these factors during a spring bloom in Lake Muggelsee (Berlin). It was found that while all three factors influenced phytoplankton growth, temperature and photoperiod were more important than LE. Both the intensities of the factors and the interactions between them influenced each species to a different degree. The results may help improve our understanding and ability to predict shifts in phytoplankton communities caused by weather patterns and climate change.


A static electric field enables 1 + 2-photon coherent control of the photoexcited carrier population in semiconductors. A theory based on the Franz-Keldysh effect is compared to results of an experiment in (100) GaAs.


Little is known about the relationship between an entrepreneur and his business coach, as very few studies have examined this question, in Tunisia or internationally. The purpose of this paper is to develop a better understanding of the relationship that Tunisian entrepreneur has with his business coach, through the study of factors, which are decisive in the success of this relationship, especially trust, communication and commitment.,This study used a questionnaire to gather information about entrepreneurs who created their small businesses between 2015 and 2018. First, factor analysis was conducted on several variables to extract the underlying dimensions. Then, a bivariate analysis was performed to identify and analyse which factors are responsible for the success of the relationship between the entrepreneur and his business coach.,The findings of the study showed that the factors identified as being critical to the success of the relationship between Tunisian entrepreneur and his business coach, include know-how, the give-and-take strategy, meeting needs of the entrepreneur, sharing knowledge and the involvement of the coach in the project during the business creation process. However, limited trust, comprehensive listening and mutuality of relationships were not statistically significant.,Whilst study results are partially consistent with the literature, it is surprising that some factors as comprehensive listening, knowledge sharing and relationship mutuality do not really consolidate the entrepreneur's relationship with his coach. By harnessing this result, it is desirable that a more in-depth examination of success factors be carried out to allow more accurate inference to be drawn from the survey.,Whilst study results are partially consistent with findings from the literature, it is surprising that some factors, as comprehensive listening, knowledge sharing and relationship mutuality does not significantly contribute to the success of the relationship between Tunisian entrepreneur and his business coach. Taking this into account, it would be desirable that a more in-depth examination of success factors be carried out to allow more accurate inference to be drawn from the survey.,The paper contributes by analysing critical success factors of the relationship between an entrepreneur and his business coach in a less well-researched area since very few studies have examined this question, in Tunisia or internationally. Conceptually, it offers a better understanding of how the entrepreneur and his coach behave during the business creation process.


BACKGROUND
Over the last 25 years clinical trials have reported improvement in the management of leukaemia leading to improved survival. In this paper we present the population-based survival patterns of leukaemia over the last two decades from East Anglia.

METHODS
Data on leukaemia from the East Anglian cancer registry were analysed to study survival based on age and time period at diagnosis. Kaplan-Meier survival was calculated for children (ages 0-14) and for adults (ages 15+) separately, for the main leukaemia sub-types.

RESULTS
A total of 2044 males and 1524 females with leukaemia were registered between 1971 and 1990, of whom 158 (7.7 per cent) and 123 (8.1 per cent) were aged less than 15 years at diagnosis. In children, five-year survival was significantly better for females for all leukaemias (p = 0.02) and for acute lymphoid leukaemia (ALL) (p < 0.01). Infants and older children had the worst prognosis as compared with children aged 2-9 years. Analysis by quinquennium of diagnosis showed a highly significant improvement in survival (p < 0.00001) for children with ALL in the later decade (1981-1990). In adults, patients with lymphoid leukaemia survived better as compared with the myeloid subtypes (p < 0.0001). Analysis by year of diagnosis in five-year calendar period showed a significant improvement in survival for acute myeloid leukaemia (p < 0.01), chronic myeloid leukaemia (p < 0.05), chronic lymphoid leukaemia (p < 0.05) and for the four types together (p < 0.001). Survival decreased with age for each subtype.

CONCLUSIONS
Age is an important predictor of survival. There was a significant improvement in survival with time for all subtypes except ALL in adults.


Metamaterial emitters based on electromagnetic band-gap (EBG) structures have previously been studied for controlling the angle and polarization of near-IR emissivity from a surface. Here, we investigate PEC backed nematic nanoparticle arrays that can be tailored to have custom angle-selective emissivity in the near-IR. Compared with structures requiring top-down fabrication methods, nanoparticle arrays have the potential to offer low-cost fabrication for large area coatings. A genetic algorithm is employed to synthesize a Pd nanorod array in a dielectric host medium that possesses low emissivity normal to the surface and high emissivity at a targeted oblique angle.


The ocean is a natural link for economic, trade, and cultural exchanges between countries. The "21st Century Maritime Silk Road" is a new type of trade road proposed by China to connect the world under the changing situation of global politics and trade. Based on the AIS data of global dry bulk carriers in 2014, this paper selected and counted AIS data of 26 countries along the "21st Century Maritime Silk Road" to build a dry bulk shipping network with the number of routes and the number of trades. The two types of networks constructed are analyzed using primary flow analysis and multiple flow analysis, with a view to providing support and basis for the construction of the "21st Century Maritime Silk Road" and trade cooperation between countries. The results show that: Singapore is the most important node in both networks; the dry bulk shipping network hierarchy of the number of routes is more obvious; the multiple flow analysis results show that China is at the first level in the dry bulk shipping network with the number of routes.


contribute to the effective assimilation of the discipline "Latin language" in a rapidly changing and developing modern society. Specific techniques for the development of critical thinking technology and the organization of independent work of students are described in detail, namely: the "Basket of concepts, terms ..." technique, "Marginal notes", "Graphic diagrams", "Mental mapping" and the "Marathon" method. The authors examined the advantages of each of the above technologies, modeled the learning process with their application, and also provided the author's schematic tables that clearly show the use of a particular method. The conclusion was made that the use of the active learning methods discussed in the article contributes to the development of personal qualities, stimulates the need to move away from outdated patterns of behavior and to adjust according to the needs of society and modern reality, which, in turn, leads to the formation of completely new characteristic features, goals and objectives for the learning process itself.


In the present studies, the long term effects of IFNα on thyroid function and thyroid autoantibodies were evaluated in 42 patients with chronic viral hepatitis type C treated with IFNα for at least 4 months. Before IFN treatment, 41 patients tested were all euthyroid. Five (12%) out of 24 patients tested had positive tests for thyroid autoantibodies. MCHA/TPOAb was detected in all 5 and TGHA/TGAb in 3 out of these 5 patients. Six to 10×106 units (U) of recombinant or natural IFNα were given intramuscularly daily for the first 2 to 4 weeks, followed by 3 to 10×106 U thrice weekly for the subsequent 14 to 22 weeks. Thyroid dysfunction and/or rises in titers of thyroid autoantibodies were observed in 6 patients during IFNα treatment; clinically overt thyroid dysfunctions, destructive thyroiditis and thyrotoxicosis of unidentified etiology, developed in 2 patients 4 to 5 months after start of IFN treatment, subclinical hypothyroidism with a slight increase in serum TSH concentrations but no serum thyroid hormone alternations was observed in 2 patients, and increases in titers of thyroid autoantibodies without thyroid dysfunction were found in 2 patients. Thus, IFNα exacerbated thyroid autoimmunity exclusively in all patients with positive tests for thyroid autoantibodies prior to treatment, but did not induce thyroid autoimmunity in thyroid autoantibody-negative patients. These data suggest that the prolonged IFNα therapy can lead to exacerbation of thyroid autoimmunity in susceptible (thyroid autoantibody-positive) patients.


Objective: To investigate the effects of intravenous thrombolysis therapy with alteplase on neurological function, coagulation function and serum inflammatory factors in patients with acute cerebral infarction. Methods: A total of 96 patients with acute cerebral infarction admitted to our hospital from September 2017 to October 2019 were randomly divided into two groups, with 48 patients in each group. The control group (n=48) received routine treatment, and the observation group received intravenous thrombolysis therapy with alteplase on the basis of routine treatment. The neurological deficit score, prothrombin time(PT), activated partial thromboplastin time (APTT), tumor necrosis factor-a level (TNF-?), and high-sensitivity C-reactive protein (hs-CRP) were compared between the two groups after 15 days of treatment. Results: After treatment, NIHSS scores in both groups were lower than those before treatment; PT levels were increased, while APTT, TNF-? and hs-CRP levels were all decreased in both groups, and the changes in the observation group were greater than those in the control group, with statistically significant difference (P<0.05). Conclusions: Intravenous thrombolysis therapy with alteplase can improve the neurological function, coagulation function and serum levels of inflammatory factors in patients with acute cerebral infarction, which is worthy of clinical application.


We show that, given a bounded Reinhardt domain D in Cn, there exists a hyperconvex domain Ω such that Ω contains D and every holomorphic function on a neighborhood of D extends to a neighborhood of Ω. As a consequence of this result, we recover an earlier result stating that every bounded fat Reinhardt domain having a Stein neighbourhoods basis must be hyperconvex. We also study the connection between the Caratheodory hyperbolicity of a Reinhardt domain and that of its envelope of holomorphy. We give an example of a Caratheodory hyperbolic Reinhardt domain in C3, for which the envelope of holomorphy is not Caratheodory hyperbolic, and we show that no such example exists in C2.


The paper deals with the design of flux-weakening control for high-speed surface-mounted permanent-magnet machine (SM PMM) for aircraft starter/generator applications. The reported detailed analysis of a machine-converter system gives a good insight into the plant's dynamic properties and leads to a successful controller design. For both motoring and generating modes, the small-signal analysis has been performed, linearized system mathematical models have been developed and the equivalent transfer functions have been derived. Based on these, a control approach that guarantee a specified system performance is developed and reported. The results are verified by time domain simulations.


The cry for rights arises in most nations. Systems of communication and international organizations, both voluntary and intergovernmental, send those cries throughout the world. Champions of human rights have trouble finding effective ways to act. It was the triumph of the Enlightenment that it enunciated human rights with an unprecedented power and universality. The Declaration of Independence is a good example of the faith of the Enlightenment. The horizontal limitation usually defines an in-group, geographically and socially cohesive, affirming itself in relation to outsiders. The New Testament declaration of the coming Kingdom of God renewed the same double theme. Occasional movements beginning in the Middle Ages related the religious vision of a transformed future to the pains of the lower social classes. The history of the nineteenth and twentieth centuries is a commentary, both pathetic and sardonic, upon the high hopes of the Enlightenment.


Hemangioma of the ovary is reported in a 23-year-old woman. In a review of the literature, 18 such tumors were reported previously. The incidence appears higher in the group younger than 30 (62%). Cavernous hemangioma was the most common type. The size of the tumors ranged up to 12 cm in diameter. The one recorded here is the largest yet reported. Two of the reported ovarian hemangiomas were accompanied by ascites which disappeared after the tumor was removed surgically.


Although multicentre clinical trials do increase analytical complexity many of the problems of drug evaluation can be overcome by getting the organisation right, accepting that this includes the trial plan and case record forms (and the care with which all three are tested). For many the word 'organisation' conjures up a picture of dull plodding. A good deal of plodding is involved but it is only dull for those who are determined to repeat the past mistakes of themselves and others. Purists seek multicentre homogeneity and their wish to achieve this may blind them to the impossibility of doing so. Realists recognise the existence of heterogeneity and while acknowledging the difficulties, welcome the opportunities that it provides. The literature about multicentre trial organisation (Peart, 1973; Boissel & Klint, 1979; Cancer Research Campaign Working Party, 1980; IPPPSH Collaborative Group, 1984) means that any further attempt to describe needs will involve committing the sin of repetition, but an attempt is made on the following pages to emphasise some matters that are important and sometimes neglected. If we are considering multicentre trials we are talking about randomised controlled experiments. A multicentre trial usually involves several and sometimes many centres. All use the same trial plan and case record forms. The same methods of data verification must be applied for information from all centres. Information from each centre or from groups of centres should be examined separately but the results from all centres are pooled for the main analysis. The more centres, the more care is needed to make sure they all work in a uniform way and the difficulties of doing this increase in proportion to their geographical spread. When centres are in different countries, national differences in medical practice, including treatment, must be taken into account. If long term follow-up is needed, the difficulty of maintaining a stable and effective organisation throughout the trial must be anticipated. A multicentre trial may be necessary to get information about a large number of patients within a reasonable time, and if so it must be done. But a single centre trial, or several trials examining the same problem in different ways, may be more useful. So only organise multicentre trials when you must and when they are necessary. Temper enthusiasm with sufficient caution by testing all the procedures that will be involved before you start. And if it must be an international multicentre trial, the organisers should go on an outward bound survival course before it starts!


In this article, we propose a variational Bayesian inference-based Gaussian process metamodeling approach (VBGP) that is suitable for the design and analysis of stochastic simulation experiments. This approach enables statistically and computationally efficient approximations to the mean and variance response surfaces implied by a stochastic simulation, while taking into full account the uncertainty in the heteroscedastic variance; furthermore, it can accommodate the situation where either one or multiple simulation replications are available at every design point. We demonstrate the superior performance of VBGP compared with existing simulation metamodeling methods through two numerical examples.


Medicare's Quality Payment Program (QPP) is a little different in 2018 than it was in 2017. Here is a guide to this year's reporting requirements.


ABSTRACT Price informativeness is the amount of private information incorporated into stock prices and measured by from regressions of stock returns on systematic risk factors. While is closely related with idiosyncratic volatility, it is not interchangeable because magnitude of systematic volatility simultaneously changes. By controlling for the systematic volatility using the double-sorting portfolio approach, we suggest a potential involvement of price informativeness with the idiosyncratic volatility puzzle. Both cross-sectional evidence of monotonic and inverse relationship between idiosyncratic volatility and and time-series evidence of disappearing alphas of the low-minus-high idiosyncratic volatility portfolios during recessions support an explanation of the idiosyncratic volatility puzzle in association with price informativeness.


The mission of ETA –Belgian sheltered workshops – mainly consists in empowering disabled people, combining this social mission with the provision of goods and services, having to keep a balance between the social aspect and the economic aspect. ETA in the Walloon Region, while rightly diverse, are focused on the employment and the defense of the most underprivileged on the labour market. The strategy to meet this objective is analysed.


Ohno's relation is a well-known relation among multiple zeta values.In this paper, we prove Ohno-type relation for finite multiple zeta values, which is conjectured by Kaneko.As a corollary, we give an alternative proof of the sum formula for finite multiple zeta values, which was first proved by Saito and Wakabayashi.


Digital innovation is creating completely new ways to do business, unlocking a new generation of micro entrepreneurs who are progressively engaging with the sharing economy. One of the most pressing challenges tax authorities face is the tax compliance of these individuals that are new to business in the sharing economy. Kamleitner, Korunka and Kirchler (2012) developed a conceptual framework that depicts key aspects that distinguish small business owners' perceptions of their tax obligation. Using Kamleitner et al.'s framework as a basis and analysing evidence from the literature, this article aims to point out additional considerations in order to develop a revised and extended framework of the factors influencing tax compliance of individuals in business in the home-sharing economy. The results of the study propose a framework depicting the four main factors that influence the tax compliance decision, namely: (1) perceived opportunity; (2) tax knowledge; (3) decision-making, and (4) person.


The structure of infinite groups in which every (proper) normal subgroup is the only one of its cardinality is investigated in the universe of groups without infinite simple sections. The corrisponding problem for finite soluble groups was considered by M. Curzio (1958).


A simple classification of organic matter types is combined with models of sedimentary environments to predict generalized trends for the distribution of normal crudes, waxy crudes, and gas on passive margins. The sequence from continental rift to open-marine conditions produces an idealized vertical organic matter type profile that has abundant terrestrial organic matter deep and aquatic organic matter shallow. In contrast, the vertical organic matter type profile that develops in deltas prograding across continental margins is from aquatic organic matter deep to terrestrial organic matter shallow. These distributions of organic matter types exercise initial control on the location of gas, waxy crudes, and normal crudes. There may be subsequent modifications and edistributions due to migration, maturation and alteration.

Genetic diversity among 126 rice accessions, including 110 Thai landraces and 16 varieties used as subspecies reference, were evaluated by three types of DNA markers, InDel (Insertion/Deletion), inter-simple sequence repeat (ISSR) and simple sequence repeat (SSR) markers. Twelve InDel primer pairs, based on DNA sequence polymorphism between '93-11' ( indica ) and 'Nipponbare' ( japonica ), were used to identify subspecies of landraces. Most of the local rice samples had either '93-11' alleles or 'Nipponbare' alleles. The scatter plotting of the principal component analysis (PCA) and dendrogram results based on InDel data could clearly classify landraces into two groups, indica and japonica . InDel and SSR markers showed the average polymorphic information content (PIC) values of 0.3707 and 0.6367, respectively. The dendrogram, based on combining InDel, ISSR and SSR data, could classify rice samples into five clusters at a cut-off genetic similarity value of about 0.70. The genetic similarity within landraces was low, indicating that Thai local rice samples have a great genetic diversity. The results of this experiment provide helpful data for rice germplasm management in breeding program. Key word: Rice, genetic diversity, DNA markers, simple sequence repeat (SSR), inter-simple sequence repeat (ISSR), insertion/deletion (InDel).

This study was undertaken to determine whether skin sensitizing antibodies are responsible for the capacity of sera from untreated ragweed sensitive patients to agglutinate red cells sensitized with ragweed extract by bisdiazotized benzidine or in tanned cell antiglobulin tests. The procedures used were a) absorption tests employing sensitized red cells; b) inhibition tests with a highly concentrated ragweed extract dialysate; and c) comparison of the hemagglutinating and skin sensitizing titers of different sera.
 Absorption tests showed somewhat variable results (probably due in large part to the heterogeneity of the system), but in a number of instances complete absorption of hemagglutinating activity was accomplished with no change in skin sensitizing activity. Sera neutralized with a highly concentrated ragweed extract dialysate showed no change in BDB test titers but significant losses of passive transfer activity. No significant correlation was observed between BDB or TCAG hemagglutination test titers and skin sensitizing titers of different sera. Together with recent information from other laboratories, these results indicate that the hemagglutinating activity of sera from untreated ragweed sensitive patients in BDB and TCAG tests is not due solely, if at all, to skin sensitizing antibodies.


ions of language actually work in the world, work so well as to give us the illusion of realism, give us the concept of truth, give us not only the concept but also the faith to sustain truth? All this without actually smoking the word or image of a pipe. Nietzsche gives no answer, though in his crucial text, 'Truth and Falsity in an Ultramoral Sense' (written when he was twenty-eight), he poses the question in the most disquieting terms. And in doing so, he compels us to face the obvious and insupportable fact: namely, language is metaphor. Here is Nietzche in a famous passage: The different languages placed side by side show that with words truth . . . matters little: for otherwise there would not be so many languages. The 'Thing-in-itelf' . . . is also quite incomprehensible to the creator of language. . . . He designates only the relations of things to men and for their expression he calls to his help the most daring metaphors. A nerve stimulus, first transformed into a percept! First metaphor! The percept again copied into a sound! Second metaphor! And each time he leaps completely out of one sphere right into the midst of an entirely different one . . . What therefore is truth? A mobile army of metaphors, metonymies, anthropomorphisms: in short a sum of human relations which became poetically and rhetorically intensified, metamorphosed, adorned, and after long usage seems to a nation fixed, canonic, and binding; truths are illusions of which one has forgotten that they are illusions; worn-out metaphors which have become powerless to affect the senses . . .8 Wittgenstein, who often sounds like Nietzsche (as Erich Heller shows),9 could not agree more. Philosophy remains in the grip of metaphors. So what does philosophy tell us about realism? It tells us, in our time at least, to look to language, and language tells us to look to tropes. Il n'y a pas d'hors texte, Derrida, unregenerate graphomane, cries; but that is only a metaphor, I think, for the increasing textualisation, the growing semioticisation, of existence, which Marshall McLuhan presaged in his slogan, 'The Medium Is the Message'. Still, if large parts of reality now seem to us a kind of writing, waiting to be deciphered, then does not realism itself become just another hermeneutic, another type of reading or misreading, authorised by certain conventions? Thus modern philosophy understands realism not as a transparent lens or clear window on eternity but as a selective, verbal interpretation of reality. What banality!


Membrane electrolysis processes can be appealing alternatives to other mine water treatment processes, especially for the selective separation and recovery of pollutants. The RODOSAN® process was developed for the simultaneous separation of sulfate and heavy metals and generation of buffering capacity. The process has been tested on a pilot scale and currently allows for sulfate separation at efficiencies of 40% to 60% with quantitative elimination of heavy metals. Sulfate is converted to ammonium sulfate, which can be used as a fertilizer. The regeneration processes have been optimized to allow more highly mineralized water to be treated in industrial membrane electrolysis cells without any process disruptions. Separation of radionuclides and valuable chemical elements from mine water, deep geothermal water and formation water is also possible using this process platform.

This paper presents our implementation of the method of parallel conjugate gradients (CGs) on the Cell Broadband Engine®(Cell/B.E.®). The solution of linear systems of equations is one of the most central-processing-unit-intensive steps in oil reservoir simulation applications and can greatly benefit from the multitude of single-instruction-multiple-data-capable synergistic processor element (SPE) cores in the Cell/B.E. processor. We assume that the linear system of equations is of standard form Ax = B, where A is a square sparse coefficient matrix. Several solvers exist with distinct advantages and disadvantages. When dealing with 1-D, 2-D, and 3-D reservoirs, the resulting coefficient matrix can be formulated as a banded matrix. This paper reports the implementation of the serial CG on the Cell/B.E. PowerPC®processor element (PPE) and the parallelization and performance analysis of CG across 1, 8, and 16 SPEs for tridiagonal (1-D reservoir grid), pentadiagonal (2-D reservoir grid), and heptadiagonal (3-D reservoir grid) matrices. Our implementation is shown to scale well with data size, grid dimensionality, and number of cores.


A mixture containing methyldithiocarbamic acid sodium salt (Vapam) and ethylenebis (dithiocarbamic acid) disodium salt (Nabam) was evaluated for its ability to preserve sugar juices. Biocide test concentrations ranged from 5 to 20 mg/kg. Samples held at 30°C for 96 hours were analyzed at regular intervals for sucrose, glucose, fructose, dextran and glucose oligomers. Positive controls were sugar cane juices spiked with 500 ppm of sodium azide or 200 mg/kg of mercuric chloride. A negative control without biocide was similarly treated.


Recorded seismic reflection waveforms contain information as to the small‐scale variations of impedance and the large‐scale variations of velocity. This information can be retrieved by minimizing the misfit between the recorded waveforms and synthetic seismograms as a function of the model parameters. Because of the different physical characters of the velocity and the impedance, we update these parameters in an alternating fashion, which amounts to a relaxation approach to the minimization of the waveform misfit. As far as the impedance is concerned, this minimization can be performed efficiently using gradient algorithms. For the inversion for seismic velocities, gradient methods do not work nearly as well; therefore, we use different minimization methods for determining impedances and velocities. However, the determination of the impedance and the determination of the velocity are strongly coupled; relaxation is most effective when this coupling is as weak as possible. Weak coupling can be achieved par...

Environmental metals are potentially toxic and can interfere with the metal-binding motifs of various critical proteins. This unit describes an electrophoretic method that can be used to measure the ability of a xenobiotic metal to bind a zinc-finger motif. Information gained using this protocol can lead to the identification of protein targets of metals and shed better light on their mechanisms of action.


In this paper, the problems of stability and stabilization for switched linear systems with finite-time unstable subsystems are revisited. Differ from the previous work, switching signal are designed with mode-dependent average dwell time (MDADT) property. Sufficient conditions are given to guarantee the switched linear systems with subsystems that are finite-time unstable being finite-time stability. Then, based on the results obtained, stabilization conditions for switched linear systems are presented to guarantee the underlying systems to be finite-time stability. A numerical example is employed to verify the efficiency of the preceding method.


Background: Solvent abuse is a particularly serious issue affecting Aboriginal people. Here we examine the association between solvent use and socio-demographic variables, drug-related risk factors, and pathogen prevalence in Aboriginal injection drug users (IDU) in Manitoba, Canada. Methods: Data originated from a cross-sectional survey of IDU from December 2003 to September 2004. Associations between solvent use and variables of interest were assessed by multiple logistic regression.

An attitude control system design is presented which produces a time-optimal Euler axis rotation for generalized spacecraft. The algorithm described uses a simple feedback control law and an explicitly calculated switching curve to perform rest-to-rest reorientations of a spacecraft along the shortest angular path in the minimum time. Direction cosines are used to compute the quaternion and the Euler rotation axis for any combination of initial and Anal orientations. A technique is presented which ensures that the maximum possible accelerations and decelerations are applied at all times during the reorientation. The vehicle can have an unsymmetric inertia matrix and can utilize continuously variable or discrete on-off torquers. Simulation results confirm that the controller provides minimum time Euler axis reorientations.


This study is conducted in order to assess the attitude of school community towards the use of sign language for instructional purpose in Bahir Dar town in the case of Yekatit 23 and Donaber primary school. In order to attain the objectives of the study, related literatures about sign language and challenges related to the use of sign language was reviewed in detail. The study used descriptive survey as a research design to explain the current trends existing in the study area. As to the samples considered for the study, because there are only two schools it appeared manageable to take them as they are. In regards to participants of the study eighty seven participants, namely 4 from the school's principals, 7 from the professional teachers in special needs, 23 regular class teachers, 13 students with hearing impairments,and 44 students without hearing impairments were involved as sample participants. With regard to data gathering instrument, questionnaire, structured interview and observation were used to collect data from the participants. The finding shows that even though teachers have positive attitude to use sign language for media of instruction, they faced many challenges and the major barriers in teachings students with hearing impairments are lack of sign language skill, lack of appropriate training and lack knowledge and experience about teaching in integrated classes. Generally the researcher suggested that policy makers and official must give priority for child's primary language. This study also confirmed that students and teachers face challenges like mismatched teacher student ratio in the classroom and the shortage of material to teach sign language as a medium of instruction.


The tech is already complicated enough, and if the terminologies aren't understood or clarified, it will further compound the complexities in this nascent industry. Everyone needs to know about this revolutionary tech, and as participants of this beautiful ecosystem it is our responsibility to simplify things as best as we can to the masses. The blockchain, the underlying technology, is the biggest innovation in computer science—the idea of a distributed database where trust is established through mass collaboration and clever code rather than through a powerful institution that does the authentication and the settlement. The biggest problems, though, have to do with clear categorization. I propose a theory of cryptocurrency periodic table policy in Altcoin markets with focus on supply rigidities identified with aggregate supply in cryptocurrency markets. The distribution of Altcoin across markets affects aggregate demand and output, however, these effects are not internalized in private financial decisions.


The Collared Pratincole Glareola pratincola has a large and fragmented breeding distribution in the Palearctic. In Italy it is an uncommon migrant breeder and the breeding sites are very patchily distributed and irregularly used, with most frequent occurrences in the N Adriatic, N Apulia, Campania, Sardinia and Sicily. We report a new breeding site for the species along the northern Adriatic coastline in the Marano and Grado Lagoon (Friuli Venezia Giulia region, NE Italy), which represents the first breeding evidence for the Friuli Venezia Giulia region.


Objective: To investigate the new type of conserving the cervix at hysterectomy.Methods: There were 62 cases of myoma of uterus from 2003 Jan to 2003 May. The improving subfascial hysterectomy was acted on 32 cases, the subfascial total hysterectomy was acted on 30 cases . The time of hyterectomy and the amount of bleeding in the operation were observed, the satisfaction of sexuality was estimated after operation.Results: The improving subfascial hysterectomy not only removed the lesion of uterus and the place that cervical cancer easy occur but also could conserve the cervix. The operation time in the improving subfascial hysterectomy was no longer than that in the subfascial total hysterectomy. The amount of bleeding in operation in the improving subfascial hysterectomy was no more than that in the subfascial total hysterectomy. The sexual activity in the patients who had the improving subfascial hysterectomy was more satisfaction than the patients who had the subfascial total hysterectomy.Conclusion The improving subfascial hysterectomy can be used for the benign patients who ask for conserving cervix.


Lead widely distributed in nature.Lead and its compounds were majority of non-biodegradable pollutants.They flow into the environment,generate pollution and hazard health through wastewater,emissions and waste residue.With urbanization,accelerating the process of modernization,lead have become the most common chemical pollutants in our lives.In recent years,more and more people pay attention to the relationship between lead and bone disease.The relevant research on bone damage mechanism has been deeply studied.Current data indicated that the toxicity of lead may be due to endocrine organ injury,indirect effecting of hormone,impacting calcium and phosphorus metabolism or bone mineral metabolism because of hormone disturbance,and hinderring the development of bone.Through injuring the bone cells and affecting calcium messenger system,lead insteads the active site of calcium in calcium messenger system and directly interferes with the function of bone cells.Authors summarized the influences of lead on the metabolism of calcium,phosphorus,the ALP,osteocalcin and osteoblast apoptosis-related gene expression.This article provides reference materials for the practice and research.


A 30-year-old male with post-traumatic priapism for 7 days was treated successfully by metaraminol bitartrate injection into the corpus cavernosum. This result suggests that an alpha-adrenagic agent injection into the corpus cavernosum should be considered in post-traumatic priapism at first.


The lines have been drawn since 1982. The conflict embodied in the relationship between debtors and creditors was evident when it became difficult to cover the payment obligations. The main aim of this paper is to treat foreign indebtedness as a form of conflict. Conceiving of the Latin American foreign debt in this way calls for a different analytical approach to the topic. The many diverse approaches that view the foreign debt as a problem, and that propose a series of possible solutions, take as their frame of reference the way in which the financial markets operate. They appeal to market mechanisms to establish a series of conditions needed to improve the economic performance of the debtor countries and to re-establish credit flows under the condi-


Based on the premise of the first-order cumulated generating series with the character of exponential growth,the background value of grey model is improved by the predictor-correcting technique to enhance the prediction precision of grey model.The numerical experimental results show that the precision and adaptability of the grey model are improved effectively.Finally,energy demand is predicted up to 2015 using the improved model coupling with the equal dimension rolling mechanism.The forecasting result indicates that energy demand will reach up to 3.19 billion tons of coal equivalent(BTCE) in 2010 and 3.63 BTCE in 2015,respectively,and it will present the huge challenge in terms of the safety of energy supply.


BackgroundThe relation between the sympathetic nervous system and the immune system has not been fully defined. Recent investigations have suggested an adrenergically driven efflux of specific β2-receptorrich lymphocyte subsets into the circulation with either exercise or infusion of exogenous catecholamines. Methods and ResultsTo determine whether acute sympathetic stimulation mediates immunoregulatory cell trafflic and function via a β2-receptor mechanism, we exercised 20 healthy volunteers before and after 1 week of treatment with either the nonselective β-antagonist propranolol or the β1-selective antagonist metoprolol. Before treatment, exhaustive exercise according to the Bruce protocol led to a marked lymphocytosis. Tsuppressor/cytotoxic (Ts/c) and natural killer cells, subtypes with the largest density of β-receptors, showed the most pronounced increases after exercise, with less impressive elevations in Thelper and B cells. With respect to function, exhaustive exercise led to a decrease in concanavalin A-stimulated IL-2 receptor expression and [3H]thymidine incorporation while enhancing natural killer cell activity. One week of propranolol therapy blunted the exercise-induced increases in circulating Ts/c and natural killer subpopulations as well as the previously observed alterations in cellular immune function. Treatment with the β1-selective antagonist metoprolol, however, did not impair the influence of exercise on any of the above parameters. ConclusionsAcute sympathetic stimulation by exhaustive exercise leads to selective release of immunoregulatory cells into the circulation with subsequent alterations in cellular immune function, either secondary to subset changes or as a result of direct catecholamine effects on function. These changes are attenuated by propranolol but not metoprolol, suggesting a β2-mediated mechanism.


Traditional economic tool-life models assume a homogeneous cutting environment, where a tool's continued service is irrespective of its condition. It is wellknown that the quality of a machining process is significantly impacted by a tool's wear-and-tear. To ensure good machining quality, tool assignment should consider the wear level of the tool as well as the type of machining job to be performed. This paper presents a dynamic management model for cutting tools that emphasizes the cost of machining quality. The model describes a heterogeneous environment typical of computerized manufacturing systems, where a tool carries out variable machining assignments during its life. The formulation is a stochastic dynamic programme, which determines optimal preventive actions based on a periodic evaluation of the tool's operating conditions. Tool deterioration is described as movement to different operating states (increasing levels of tool wear) and job assignment of tools is state-dependent. A tool's optimal economic life is also determined within the context of variable machining. The cost of quality-deviation is assessed using Taguchi's quality-loss function.

structures containing particles of sizes between 1 and 100 nm (1 nm=10-9 m), in an unbound state or in the form of aggregates. Examples of natural nanomaterials include the capsid structures of viruses, some butterfly wing scale patterns and colloidal fluids, such as milk and blood. Synthetic nanomaterials, on the other hand, are engineered and manufactured to have well-defined mechanical, physical or chemical properties, which makes them suitable for technology and in industrial processes. In particular, metal nanomaterials and metal oxide nanocomposites have important applications in optoelectronics, sensing, drug delivery and catalysis. Bimetallic nanoparticles have for instance been shown to be promising catalysts for processes including the water-splitting reaction and the reduction of CO2, and they represent a highly promising path towards sustainable energy generation, storage, transmission and utilisation on a global scale. The enhanced activity of bimetallic nanoparticles has been attributed to synergistic effects between the metals and defect sites in nanocrystal structures.

OBJECTIVE To establish a fast and simple method for determining of Ornidazole tablets.METHODS Fluorescence spectrophotometry was adopted at λ_(ex) 355 nm and λ_(em) 412 nm.RESULTS The linear range was 1.0×10~(-6)-2.0×10~(-4) mol·L~(-1) with the RSD of 3.52%.CONCLUSION This method has been successfully applied to the determination of Ornidazole tablets with satisfactory results.


The fi rst vertebra of the spinal column is called Atlas. The name comes from a Hemitheos Atlas that symbolizes the heavy task of the fi rst cervical bone. When Atlas acted with Titans against Zeus in the war, Zeus punished him with holding the Heavens on his shoulders forever. Atlas supported the Heavens (the Earth, sphere) from the ranges now called the Atlas Mountains.


We have studied the photochemical reactions (λ= 365 nm) of nineteen vanadium(V) chelates of structure VOQ2OR where Q is the 8-quinolyloxo ligand and R is an alkyl group. In all cases photolysis proceeds in a first-order fashion to yield the vanadium(IV) chelate VOQ2 identified by u.v.-visible and e.s.r. spectroscopy. The VV chelates photoinitiate free-radical polymerization and the quantum yields of photoinitiation with methyl methacrylate as monomer have been determined and compared with the quantum yields of chelate photodecomposition. Each molecule of chelate decomposing gives rise to one initiating radical.The dependence of the quantum yield of photodecomposition ϕd on the nature of R is discussed. The inductive effect of R, which influences the natures of the VO and V—OR bonds, also affects ϕd and a correlation between the stretching frequency of VO and ϕd has been found.The photolytic products in benzene solution have been examined by spin-trapping and g.l.c. techniques; results are consistent with the primary formation, isomerization and β-scission of alkyloxy radicals.


Purpose: The study examined the virulence factors and antibiotic resistance patterns of Escherichia coli strains isolated from urine samples of UTI patients at the ObafemiAwolowo University Teaching Hospitals Complex, Ile-Ife. Methods: Virulence tests for haemolysin, biofilm formation encapsulation and toxin production as well standard antibiotic susceptibility tests and phenotypic tests for ESβL production were conducted on the isolates under study. A further search for genes encoding ESβL production was made at the molecular using the Polymerase Chain Reaction/Pulsed Field Gel Electrophoresis method. Results: Of the thirty-six strains evaluated, all isolates were found to be resistant to at least two classes of antibiotics used in this study, of which 28 strains (77.8%) were found to carry a CTX-M ESβL gene type of the two genes tested. Encapsulation was found to be the most commonly encountered virulence factor associated with these isolates (97.2%). Conclusion: Multiple antibiotic resistances (in this case ESβL) can be said to be critical to the survival of uropathogenic E. coli in this environment.


The EQ is a kind of index to measure one's emotion level,is the non-intelligence factor that can determine one's success.Because of all kinds of reasons from family,society,school and oneself,some problems exist in the EQ development of our country's undergraduates,so,we should make EQ education become a system engineering to train the modern students with both ability and moral integrity through the effect of whole society.


Does campus policing predominantly involve the enforcement of law or does it involve more traditional security functions such as plant protection, preventive maintenance, and the regulation of student conduct? In what ways is university policing, a form of private policing, similar to and different from the model of municipal policing? This fine study addresses these and other questions.


In the article the productivity of the prefix, reconstructed as *bhin a hypothetical Proto-Indo-European (PIE) language, using the lexical material of Latin, Ancient Greek, Germanic and Slavic languages, is explored. It is shown that the derivational values of the prefix under research allow its genetic link with prepositions having values of "near", "about", "around", with a PIE reconstruction *ambhi, according to S.A. Starostin.


According to China's 14th Five-Year Development Plan, China aims to peak its carbon emissions by 2030 and achieve carbon neutral by 2060, which will be a major strategy for China to implement in the coming period of time. All kinds of industries need to take the industry characteristics into account and gradually form relative carbon reduction targets according to the National Carbon Summit Action Program. Under the constraints of carbon emission reduction, enterprises face trade-off when making emission reduction decisions. How to systematically optimize the profitable and environmentally friendly decisions, under the consideration of carbon emission production, is gradually becoming a main concern of regulated enterprises. In this paper, a Cournot game model is constructed to explore optimal production carbon abatement decisions for two oligopolistic firms, under the governance of a cap-and-trade mechanism. Real case data collected from China's airlines is an example to test the validity of our model. The qualitative analysis shows that, through a reasonable output and emission reduction investment, companies are capable of efficiently minimizing the negative impact brought about by the carbon trading system. A numerical experiment indicates that the companies on one side can reach a decision equilibrium in some circumstances, but on the other side, there exists a lack of incentive to reduce their emissions. Additional government incentives or increased investment in technological improvements will be needed to encourage companies to further reduce carbon emissions. In this paper, while analyzing the choice of emission reduction strategy for enterprises under the carbon trading system, it also provides effective emission reduction approaches for the government and industry managers, hoping to provide some references for the establishment of emission reduction system and policy formulation.


A study was conducted during 2006–08 on the effect of pesticides (mancozeb, endosulfan and chlorpyrifos) on tomato (Solanum lycopersicon L.) cropped soil for total microbial population, symbiotic and asymbiotic nitrogen bacterial counts and microbial activities. The physico-chemical soil properties were not affected by pesticide applications, however, the viable microbial counts were reduced drastically even at lower concentrations of applied pesticides. All pesticides had moderate to high inhibitory effect on phosphatase and dehydrogenase activity, though the effect of chlorpyrifos was most persistent. Chlorpyrifos at 100 mg/kg inhibited more than 35 and 50% activity of dehydrogenase and phosphatase enzymes, respectively, even after 35 days of treatment. Mancozeb was highly toxic at the initial stage, inhibiting 90% dehydrogenase and 65% phosphatase activity within 7 days of treatment at 100 mg/kg. The microbial respiratory activity was also highly affected in the presence of all the pesticides at 50 and 100 mg/kg levels. After 1 day of pesticide treatment, CO2 evaluation was minimum (1 mg CO2/50 g soil) in mancozeb.


This presentation presents a study of approaches to foster open innovation, including the use of crowds and social media to leverage and utilize interdisciplinary sources. Crowds are inherently interdisciplinary, and they contain experts. Wisdom can be extracted from these sources. However, the peril of bias and "group think" could be detrimental if not carefully exposed. The process of innovation benefits from a diversity of skills and perspectives. There are technology and communication trends that enable unprecedented access to information, people and even group sentiment, offering new ways to collaborate, connect producers to consumers to investors, and ultimately to innovate. As an example, we will highlight the potential value of applying crowd-sourcing models to commercial and government environments


The article presents the analysis of problems connecting with the deepening of petroleum refining. It has been shown that the activation of crude oil due to putting additives polycyclic arenes can significantly increase the yield of light fractions with a straight distillation of crude oil at the cost of effect on supramolecular structures of petroleum fractions. On the basis of these studies have been ascertained that putting 1.5% wt additive polycyclic arenes allocated from coal tar into the oil, make it possible to increase the total yield of light fractions by 5-6% wt. Along with this change of boiling temperature distribution into allocated light fractions has been observed.


Adaptive IIR filters implemented in cascade-form are attractive due to the ease with which their stability may be monitored. Four cascade-form structures are compared for use in adaptive filtering with respect to complexity of implementation, error surface geometry, and adaptation speed. The four structures include a cascade of second order pole/zero sections, a cascade of second order all-pole sections followed by a tapped delay line, and two new structures. The latter pair includes a tapped cascade, which is a cascade of second order all-pole sections whose output is constructed as a weighted combination of signals tapped from the cascade. The second new structure is a modification of the tapped cascade that yields orthogonal signals at the taps of the cascade. It is shown that the tapped cascade provides the best overall performance in the respects noted above.


Abstract : A theoretical study of the use of a direct reception Nd: YAG laser radar for target detection is reported. This work builds from a mathematical system model which incorporates the statistical effects of propagation through atmospheric turbulence, target speckle and glint, and receiver noise; both photomultiplier and avalanche photodiode receivers are considered. Results are presented for the receiver signal-to-noise ratio which show, explicitly, the deleterious effects of atmospheric scintillation on system performance. The structure and performance of the optimum likelihood-ratio processor for single-pulse target detection are analyzed. (Author)


The urban landscape of traditional cites was the product of its culture representing its historical and sociocultural characteristics. These diverse urban landscapes of cities around the world have been transformed over the past four decades into what is referred to as an international style for economic purpose. While this transformation increases the potential of the city entering into the world market, promoting economic growth, social development and modernization, at the same time it causes social polarization, inequality and in most cases losing its traditional urban character. The critical questions arise in this realization are: what are the influences of this transformation on the urban identity of cities? And, what impacts that would have on social life? The paper discusses the above questions through the case study of Amman City. It explores factors contributed to the historical formation of the urban identity of Amman, its transformation since the Post-World War II, and finally, presents a critique on the rapid transformation over the last three decades and its impact on the socio-cultural environment of the city.


Bacteriology (Dr. L. P. Garrod). Films show numerous bacteria of three principal types, small Gram-positive cocci, short Gram-negative bacilli, and fusiform Gram-negative bacilli. Cultures yield a growth of Streptococcus salivarius and Pfeiffer's bacillus. Dr. Garrod concludes that the bacteriology of this material suggests infection from the mouth or pharynx. The child's paternal grandfather is said to have similar, though larger, depressions in the same position on both ears, but these have occasioned no inconvenience.


The pure lipopolysaccharide of Shigella sonnei phase II was submitted to acid hydrolysis (0.1 N H2SO4, 20 min, 100°), and from the hydrolyzate the specific fragment was isolated and purified. The analysis of the specific fragment showed that it contained about 70% sugar; the major constituents were glucose, galactose and heptose in the approximate proportion 3:2:2.2. 2-Keto-3-deoxyoctonate (3.2%), glucosamine (3.4%) and O-phosphorylethanolamine (6.0%) were also found. The molecular weight of the specific fragment estimated by gel filtration ranged between 4,500–5,000. Electrophoretic experiments indicated its acid character: the isoelectric point was near 2.9.


As a scientist, I have written and spoken about the topic of human embryology for many years, and I am continuously reminded of both the mystery surrounding human embryos and of the passionate feelings they evoke. The prenatal origin of human life has fascinated biologists, philosophers, and religious thinkers for a very long time.1 Yet in the modern age, thinking about the earliest stages of human life—and considering the value of life at its very beginning—has become entangled with some of the most emotionally compelling issues society and individuals face, including the bearing of children, the relief of human suffering, and the pursuit of scientific knowledge. For the vast majority of human history, prenatal development has been a profound mystery. A host of folklore, mythology, and religious beliefs have arisen surrounding the origin of human life, but until quite recently, we knew very little for certain beyond the basics that can be readily observed; that after a period of confinement lasting approximately nine months, a baby is brought forth from the mother's womb with much effort and with considerable risk to both mother and child. Over the last several decades, science has begun to unravel the mysteries of human development. Yet despite these advances in our understanding, in many ways, the true nature of our embryonic origin remains shrouded in darkness, mystery, and controversy. One of the challenges we face in thinking about the human embryo is that embryonic development falls outside every-day human experience. Typically, we formulate our opinions about the world based on what we observe, what we feel about our observations, and what we conclude from these observational and emotional events. We develop an intuitive sense of what things are and how they fit into our lives based on our experiences with them over time. This kind of intuitive understanding allows us to overcome our immediate reactions in favor of what we know to be true overall—even when appearances might beg to differ. For example, many of us, quite understandably, react to human toddlers as members of an alien species. They are louder, messier, and consider-


we might perhaps call a neutral zone among our Lord's sayings? Sayings, I mean, in which He takes up ideas and expressions current at the time, and uses, without really endorsing them.&dquo; 1 Of such sayings he selects, as an example, that very question which Christ addressed to the Pharisees, touching the 1 loth Psalm (Matt. xxii. 45); and &dquo; it was not criticism or exegesis,&dquo; he says of it, &dquo; that were at issue. The true methods of these might well be left for discovery much later. The Pharisees were taken upon their own ground; and the fallacy of their conclusion was shown on their own premises. All we need say is, that our Lord refrained from correcting these premises. They fell within His neutral zone.&dquo;

We give a recursive definition of generalized parking function that allows us to view them as a species. From there we compute a non-commutative characteristic of the generalized parking function module, and deduce some enumeration formulas of structures and isomorphism types. We give as well an interpretation in several bases of non-commutative symmetric functions. Finally, we investigate an inclusion-exclusion formula given by Kung and Yan.


According to distributed virtue reliabilism (Palermos, 2020b), epistemic collaborations—such as Transactive Memory Systems and Scientific Research Teams—can be held epistemically responsible at the collective level. This raises the question of whether participants of epistemic collaborations are exempt from being held individually responsible. In response, this paper explores two possible ways in which attributions of individual responsibility may still be appropriate within epistemic collaborations: (I) Individuals can be held epistemically responsible for their individual shortcomings, but no amount of individual epistemic responsibility can replace collective epistemic responsibility. (II) Even if it is denied that participants of epistemic collaborations can be held epistemically responsible at the individual level, they may be held structurally , perhaps morally , and even legally responsible at the individual level for breaking joint commitments necessary for the effective coordination of the epistemic collaboration.


We present "DiViMe", an open-source virtual machine aimed at packaging speech technology for real-life data, and developed in the context of the "Analyzing Children's Language Environments across the World" Project. This first release focuses on Speech Activity Detection, Speaker Diarization, and their evaluation. The present paper introduces the set of included tools and the current workflow, which is fo-cused on making minimal assumptions regarding users' technical skills. Additionally, we show how the current DiViMe tools fare against three sets of challenging data. In a first experiment, we look at performance with samples extracted from daylong recordings gathered using the LENA TM system from English-learning children. We find that the performance of the tools currently in DiViMe is not far from that achieved by the LENA TM proprietary software. In a second experiment, we gen-eralize to other samples of child-centered daylong files, gathered with non-LENA TM hardware from non-English-learning children, showing that performance does not degrade in this condition. Finally, we report on performance in the DiHARD 2018 Challenge Test Data. Originally conceived in the "Speech Recognition Virtual Kitchen", DiViMe is a promising platform for packaging speech technology tools for widespread re-use, with potential impact on both fundamental and applied speech and language research.


Over the past few decades, energy is the backbone of technology and economic development. In addition to men, machines and money, 'energy' is now the fourth factor of production. The objective of this paper is to design and study an environment friendly ammonia water vapour absorption refrigeration system of unit capacity using Ammonia (R717) as a refrigerant and water as a absorbent working fluids and run by exhaust water Solar Thermal Set Up. The system is designed and tested in Thermal Engineering lab of Agnos College of technology RKDF University Bhopal Madhya Pradesh for various operating conditions using hot water as heat source. In this paper, performance of the fabricated system is outlined with respect to various operating conditions related to heat source, condenser, absorber and evaporator temperatures. The solar heating unit remains idle in the summer months. Also the solar potential is at maximum in the summer other months of year.


Purpose: Apatite deposits within tendons are common conditions that may cause pain, loss of motion, and difficulty with function among active individuals. The modality known as Extracorporeal Shockwave Therapy (ESWT) has been utilized successfully in lithotripsy and has been investigated for its possible role in aiding calcification. This literature review aims to look at the state of evidence among previous randomized controlled trials examining the effects of ESWT on calcification within tendons in the upper extremities. Methodology: Extraction Systematic literature searches for randomized controlled trials between 2012-2022 were performed in the databases of PubMed, Academic Search Index, and Directory of Open access Journals, CINAHL, between November 3rd to November 11th, 2022. A total of four randomized controlled trials (full text available, PEDro score > 7, and conducted in the past 10 years) with a total of 238 subjects met methodological quality guidelines using the PEDro scale. Results: A total of 1,042 articles were screened, and 4 studies with a total population of n = 238 were included in the review. With trials using a variety of adjunct therapies and with differences in frequency, dosage, and treatment volume a meta-analysis was not conducted. There were statistically significant improvements reported in terms of pain and function in ESWT on calcific tendinopathy in 1 study (n= 42). On the other hand, non-ESWT clinically significant differences were found in the use of ESWT in 2 of the studies (n=144), and no effects in 0 of the studies (n= 0). A small majority of studies suggest that in the management of tendinopathies of the upper and lower limbs, ESWT has a clinically significant effect on pain and functional outcomes. Conclusion: A review of current randomized controlled trials presented limited evidence for the use of ESWT for upper and lower limb tendinopathies in humans. While the use of ESWT may improve pain and functional outcomes in humans, further studies on dosing, prescription, and risk of bias assessment are suggested.

This work describes the preparation of a selective receptor for the rapid, selective, and sensitive electrochemical flow injection analysis of zinc using air stable lipid films supported on a methacrylate polymer on a glass fibre filter with incorporated artificial receptor. The selective receptor was synthesised by transformation of the –OH groups of resorcin4arene receptor into phosphoryl groups. These lipid films were supported on a methylacrylate polymer (i.e. methacrylic acid was the functional monomer for the polymerisation, ethylene glycol dimethacrylate was used as the crosslinker and 2,2′-azobis-2-methylpropionitrile as an initiator). A minisensor device was constructed for the electrochemical flow injection analysis of zinc based on air stabilised lipid films supported on a polymer. The device can sense the analyte in a drop (75 µL) of sample. Zinc was injected into flowing streams of a carrier electrolyte solution. A complex formation between the calix4arene phosphoryl receptor and zinc takes place. This enhances the pre-concentration of zinc at the lipid membrane surface which in turn causes dynamic alterations of the electrostatic fields and phase structure of membranes; as a result ion current transients were obtained and the magnitude of these signals was correlated to the substrate concentration. The response times were ca 5 s and zinc was determined at concentration levels of nanomolar. The analytical curve was linear in the concentration range 1.00 × 10−7 − 1.20 × 10−6 M with detection limit of 5.00 × 10−8 M and a relative standard deviation lower than 4%. The effect of potent interferences included a wide range of other metals. As an analytical demonstration, trace concentrations of Zn(II) were successfully detected in real samples of waters without any laborious and time-consuming treatment.

We describe an empirical model to predict the 1-AU arrival of coronal mass ejections (CMEs). This model is based on an effective interplanetary (IP) acceleration described by Gopalswamy et al. [2000b] that the CMEs are subject to, as they propagate from the Sun to 1 AU. We have improved this model (1) by minimizing the projection effects (using data from spacecraft in quadrature) in determining the initial speed of CMEs, and (2) by allowing for the cessation of the interplanetary acceleration before 1 AU. The resulting effective IP acceleration was higher in magnitude than what was obtained from CME measurements from spacecraft along the Sun-Earth line. We evaluated the predictive capability of the CME arrival model using recent two-point measurements from the Solar and Heliospheric Observatory (SOHO), Wind, and ACE spacecraft. We found that an acceleration cessation distance of 0.76 AU is in reasonable agreement with the observations. The new prediction model reduces the average prediction error from 15.4 to 10.7 hours. The model is in good agreement with the observations for high-speed CMEs. For slow CMEs the model as well as observations show a flat arrival time of ∼4.3 days. Use of quadrature observations minimized the projection effects naturally without the need to assume the width of the CMEs. However, there is no simple way of estimating the projection effects based on the surface location of the Earth-directed CMEs observed by a spacecraft (such as SOHO) located along the Sun-Earth line because it is impossible to measure the width of these CMEs. The standard assumption that the CME is a rigid cone may not be correct. In fact, the predicted arrival times have a better agreement with the observed arrival times when no projection correction is applied to the SOHO CME measurements. The results presented in this work suggest that CMEs expand and accelerate near the Sun (inside 0.7 AU) more than our model supposes; these aspects will have to be included in future models.

The Faculty of Engineering at the University of Auckland recognizes the importance of information literacy (IL) to both the academic learning and the subsequent professional practice of its students. A collaboration between a Senior Lecturer and two Librarians explored ways of improving the IL skills of a post-graduate engineering class. The pilot comprised: a pre-test of students' IL skills, a one-hour hands-on-computer tutorial tailored to a course assignment, a post-test of the student's IL skills, the assignment results, and students' evaluations of both the tutorial and the course. In this paper we will discuss the aims, methods used, results achieved, lessons learnt, and proposals for future improvements.


Walker Rumble and Keith Bird are presenting a course in conjunction with the journalism department at the University of Bridgeport: "The Historian and the Newsreel." They would appreciate the suggestions of anyone with experience in teaching a similar course. Paul Vanderwood reports from San Diego State College that their "history through film" program just under way, is working out very well. He indicates that not only the students, but even some of the more skeptical teachers there have been stimulated by the project. The latest project of the British Universities Cortsortium on film is a film to teach some of the techniques of reading medieval handwriting.


Nearly every day, the Mental Health Center of Western Maryland gets calls from people who need care but have no insurance and cannot afford to pay out of pocket. The Hagerstown, Md., center cares for about 1,600 patients every month, but there are many in need that the center has no choice but to turn away.


This study discusses the issue of disposable and reusable medical devices in the context of the circular economy. Its objective is to analyze the opinions of physicians in gynecological practice on the use of disposable and reusable gynecological speculums (GS). A questionnaire survey was carried out in a sample of 206 healthcare facilities in the Czech Republic. In addition to this, the cost of both examination methods was calculated and compared using data provided by a gynecological department of a typical district hospital. The calculations and cost analysis were performed using the life-cycle costing (LCC) method. The economic comparison shows that the use of disposable gynecological speculums is less expensive, having, however, a greater negative impact on the environment. The cost of reusable speculums for 25 examinations per day for 15 years is EUR 51,579, while it is EUR 23,998 for disposable speculums for the same use and time horizon. The questionnaire survey shows that both physicians and patients are more likely to prefer disposable speculums for examination, although without a clear rationale.

Design curves have been prepared for prestressed rectangular beam section based on BS 8110, for determining area of steel for any given cross section, for stresses in concrete and steel and for the design moment. The design moment and the area of steel have been expressed in dimensionless form in terms of cross sectional dimensions and the characteristic strength of concrete. The choice and combination of design parameters result in considerably less number of curves as aid for design of rectangular prestressed beam sections, than those reported in CP 110 (Part 3).


This essay reviews Bourdieu's conceptions, emphasizing the notion of social fields as a result of unequal distribution of different types of capital (types of power), as a field of forces and struggles, according to the relative positions in a relational space. Follows a critical review of the institutional perspective and how the notion of field was incorporated. We believe that Bourdieu's conceptions may offer another look at the issue of social action and change. In this sense, some implications of using Bourdieu's conceptions in organizational studies are explored.


The periodic replacements criterion of rail is calculated on the basis of the research result of RTRI in Japan. It is suggested that the service life of the continuous welded rail(CWR) is estimated by the relationship between the rail surface irregularity according to the accumulated passing tonnage and bending fatigue of welded part in CWR. In order to establish the periodic replacements criterion of CWR, this study measured the rail surface irregularity according to the accumulated passing tonnage, the types of track system and welding. Therefore, it is analyzed that the gas pressure welding is the worst one of the others. In addition, it is analyzed that the rail surface irregularity growth rate in ballast track is about O.02~0.03㎜/100MGT and its in concrete track is about 0.005~0.02㎜/100MGT. Finally, the result of this study is able to use the basis data to establishing the periodic replacements criterion of CWR considering rail grinding.


cases, especially where constitutional factors do not obtrude and the pre-psychotic adjustment has been adequate. Schizophrenia is a common mental maladjustment and it occurs· in young folk in a mild and fleeting manner much more often than is generally suspected.. The more malignant types of schizophrenia are happily rare; and the acute cases, though alarming, may often be brought to a successful issue by the early application of treatment. They must not be overlooked or misdiagnosed. To temporize is dangerous and certification is generally unnecessary in the initial stages. Pessimism is no longer justifiable in the schizophrenic arena, for there is a remedy at hand which, if skilfully applied, will rehabilitate the maladjusted mind and put "delusion's dusky train to flight". .

The turbulent mixing noise of a supersonic jet is calculated for a round convergent-divergent nozzle at the design pressure ratio. Aerodynamic computations are performed using the PARC code with a k-c turbulence model. Lighthill's acoustic analogy combined with Ribner's assumption is adopted. The acoustics solution is based upon the methodology followed by GE in the MGB code. The source correlation function is expressed as a linear combination of second-order tensots. Assuming separable second-order correlations and incorporating Batchelor's isotropic turbulence model, the source term was calculated from the kinetic energy of turbulence. A Gaussian distribution for the time-delay of correlation was introduced. The CFD solution was used to obtain the source strength as well as the characteristic time-delay of correlation. The effect of sound/flow interaction was incorporated using the high frequency asymptotic solution to Lilley's equation for axisymmetric geometries. Acoustic results include sound pressure level directivity and spectra at different polar angles. The aerodynamic and acoustic results demonstrate favorable agreement with experimental data. Introduction Recent advances in the area of computational fluid dynamics have provided researchers with new tools for approaching aeroacoustic problems. Though the direct computation of the sound field and its propagation mechanism is the ultimate goal in an area which has been labeled as computational aeroacoustics, the extraordinary dimcult nature of these computations at the present time lead to a more practical approach, namely using the available computational resources. * Member, AIAA. Eugene A. Krejsa* and Chart M. Kira National Aeronautics and Space Administration Lewis Research Center Cleveland, Ohio 44135 Such an approach is taken here to study the high speed jet noise because of the current interest in High Speed Civil Transport (HSCT). Over a decade ago, a unified aerodynamic/acoustic prediction model was developed by GE for the Federal Aviation Administration [2]. The'aerodynamic predictions within this code are carried out by applying an extension of Reichardt's model. The three components of turbulent shearing stress are computed based upon contour integrals around the nozzle exit geometry and utilized in deriving an expression for the source strength. Though the closed form nature of Reichardt's solution has led to a versatile and relatively fast numerical scheme, the assumptions inherent in the derivations render inaccurate aerodynamic prediction for complex geometries. Reichardt's solution essentially assumes exhaust nozzle elements discharge axially. It neglects radial mean flow and swirl and does not take into account the effect of shock structure on mixing and turbulence. These assumptions, among others, could vitiate the aerodynamic predictions substantially. In the light of these assumptions the model proves insufficient for noise prediction of new lobed hypermix nozzles that are the present focus in HSCT research. To circumvent some of the pitfalls associated with Reichardt's model, a two-stage algorithm is considered in which the aerodynamic calculations are carried out independently and the resulting plume data are introduced for noise cornputation. The following computational advantages are associated with a two-stage algorithm: (1) the aerodynamic calculations can start from within the nozzle, giving a more realistic model of the exit conditions; (2) grid selection can be done independently for aerodynamic and acoustic purposes. The plume is treated as an integration of axial slices in acoustic computations; (3) proper prediction of shock-cell structure and intensity for off-design conditions improves shock noise assessment. The geometry considered in this paper is a round convergent-divergent nozzle. This particular nozzle has previously been tested aerodynamically and acoustically for NASA-Lewis by General Electric [1]. Test data has been especially helpful in assessing the CFD results before proceeding with noise computations. The flowpath is designed to obtain an isentropic, uniform and parallel flow at the nozzle exit for the design Math number of 1.4, thereby eliminating to a large degree, any shock induced noise. An axisymmetric version of PARC code with Chien's k-e turbulence model [3] has been used. The complete Reynolds-averaged Navier Stokes equations are solved in conservative law form. The viscus coefficients are det_ermined based on Sutherland's viscosity law, Stokes hypothesis and constant Prandtl number assumption. The jet plume flow field is compared with data as well as solution from Reichardt's model.


Abstract Graphene oxide (GO) is a carbon-based filler which possesses superior properties for the preparation of polypropylene (PP) nanocomposites. The homogeneous dispersion of nanofiller in a polymer matrix involves a compatibility between base and matrix. This research work analyzes the behavior of GO and its distribution in PP as well as the morphological, physical and mechanical properties of prepared nanocomposites. Since PP is non-polar and GO is polar, there may be a compatibility mismatch between filler and matrix, which may not lead to homogeneous distribution due to poor chemical interaction. Maleic-anhydride grafted polypropylene (MA-g-PP) was selected as a suitable compatibilizer in order to disperse filler into the matrix. X-ray diffraction (XRD) reveals an increase in intergallery spacing which confirms the formation of GO. Scanning electron microscopy (SEM) shows the improved distribution of GO sheets in the PP matrix for the compatibilized system. Tensile strength and modulus of elasticity are improved for the compatibilized PP nanocomposites when compared to the uncompatibilized and to the pure system. Moreover, an enhancement of storage modulus was evidenced for compatibilized nanocomposites. Polar-polar interaction between GO and compatibilizer leads to the homogeneous distribution of filler into the matrix which is clearly responsible for an improvement in the technical properties of polymer.
