Oxide films are generated using Gas-solid Reactions of CO2 within 24 hours,48 hours and 120 hours.The surface analysis by SEM and XPS indicates that all the films are compact but they have different compositions and properties, and the longer of the reaction-time,the steadier of productions.The XPS deep-scan results indicate that phosphor appears on the surface only,and does not penetrate into the interior of oxide films;however,the compositions of carbon and oxygen in the same depth are increased with the increase in reaction time,at the same time the oxide films deepens as well.The chemical analysis shows that the sample oxide films have good capability to resist corrosion.

Among the shapemaking techniques, slip casting is believed to be a method appropriate for prototypes, whereas injection molding is ideally suited for high-volume, cost-effective production of complex parts. For the last several years, GTE Laboratories Incorporated (GTE Labs) has been involved in developing injection-molding technology for ceramics and has applied this technology extensively for fabrication of silicon nitride components for heat-engine applications. Several components having a variety of cross sections and complexities have been fabricated and evaluated. The status of GTE Labs' injection-molding technology and the properties and reliability of some of the test parts are described in this paper.


The recent controversy over nanofossils in a Martian meteorite and reports of bacteria growing in basalt have once again brought the study of geomicrobiology into the headlines. Thus, Geomicrobiology: Interactions Between Microbes and Minerals, comes at a very opportune time. The book, a byproduct of a short course of the same title hosted by the Mineralogical Society of America last fall, provides an in depth look at a fascinating subject. Containing 13 chapters it begins with a review for non-specialists on microorganisms and biogeochemical cycles and concludes with the evolution of the carbon cycle. Sandwiched in between are chapters covering such diverse subjects as prebiotic chemistry, processes at mineral surfaces, biogenic magnetites, and weathering as well as chapters which focus on specific processes (i.e., microbial manganese oxidation, calcite and silica deposition by algae, sulfide mineral oxidation). The first two chapters provide background on basic microbiology, microbial diversity, and biogeochemical cycling. Emphasis has been given to the use of molecular techniques such as 16S rRNA sequence analysis. It is refreshing, however, to see the admission that although molecular approaches can be a powerful tool for getting a more accurate measure of microbial diversity, the identity and function of these newly described organisms known only by their 16S rRNA sequence, remain a mystery. For those less familiar with geochemistry the following three chapters provide background on mineral structure and chemistry as well as biological interactions with mineral surfaces. The inclusion of some basic minerology in the Banfield and Hamers chapter should be most helpful to the non-geologists. The subsequent chapters go into specific examples in more detail. A great deal has been learned in the past few years about the genetics and biochemistry of manganese oxidation and is exquisitely covered in the Tebo et al. contribution. It was surprising to see little discussion of the microbial respiration of metals and metalloids other than iron, manganese, and sulfur, that can lead to mineral deposits (i.e., uranium, selenate, arsenic). A major disappointment was the apparent lack of editing. Understandably, this volume was produced quite rapidly while one of the editors was on sabbatical. However, only a few chapters are devoid of typographical mistakes which in some case have resulted in factual errors. Nealson and Stahl state that freshwater environments typically contain 100 to 250 mM of sulfate while marine systems contain micromolar amounts (just the opposite is true). Bazylinski and Moskowitz have inadvertently created a new subgroup of Proteobacteria. The volume I received also included an insert correcting a figure in chapter 11, earlier versions did not. Suffice it to say reediting would greatly enhance the utility of this text. Despite its shortcomings, it is a good primer for the novice and an important volume for the seasoned veteran.


Two and three centuries ago, during the Spanish colonial period, the name Guatemala covered a large area stretching from the Isthmus of Tehuantepec to Costa Rica. Except from eastern Honduras southeast ward, the cultural area more or less comprised ancient Mayaland or the Mayab, as its original inhabitants called it. At the declaration of indepen dence in 1821, Guatemala lost Chiapas to Mexico, and the United Provinces of Central America then set up lasted less than two decades as a federal republic. Since that time the reduced State and later Republic of Guatemala has had a succession of autocratic governments and rulers, chielly because of the necessity of holding down the large native population. Few presi dents other than dictators like Rafael Carrera, the Conservative halfbreed who dominated politics during the middle of the past century, Estrada Cabrera at the beginning of the present one, or Jorge Ubico during the depression and Second World War, have lasted out their term of office.

The aerodynamic drag force is a crucial factor for passenger cars and trucks, where fuel economy is of utmost importance. While a lot of research has been performed to optimize the design of the upper-body of the vehicle, the flow over a rotating wheel that is enclosed by a wheelhouse is not understood to the same level. Estimates show that the addition of wheel and wheelhouse to a vehicle body, can increase its drag and lift coefficient by as much as 40 \%. With the major automobile manufacturers striving to improve the fuel economy of the vehicle, understanding the flow over a rotating wheel in a wheelhouse, offers a new dimension for the improvement of the drag coefficient of the vehicle. In the present research, the flow over a simplified car body with a wheel and a wheelhouse was studied using Large Eddy Simulation (LES). When performing an LES on a given numerical grid, it can be expected that the contributions from the subgrid viscosity model reduces on decreasing the Reynolds number of the flow. A study focusing on the dependence of the flow field on the Reynolds number was thus performed. Three Reynolds numbers based on the wheel diameter - 9 x $10^3$, 75 x $10^3$, 150 x $10^3$- were chosen for the dependence study. A comparison of the relative pressure distribution and the flow topology between the different Reynolds numbers showed that the flow over a rotating wheel in a wheelhouse was qualitatively independent of the Reynolds numbers considered in this work. Experimental results from Particle Image Velocimetry (PIV), performed on a similar vehicle model, were used to validate the numerical solution at a Reynolds number of 9 x $10^3$. The behaviour of the flow in the wheelhouse region was investigated and a new description of the flow field inside a wheelhouse, consisting of 11 vortex structures, was presented in this work. To determine the qualitative dependence between the flow field and the drag coefficient, a comparison of the flow between two geometric configurations, with different wheelhouse radius, was performed at a Reynolds number of 9 x $10^3$. It was found that the configuration with the larger wheelhouse radius had a higher wheelhouse drag coefficient and a lower wheel drag coefficient when compared to the configuration with lower wheelhouse radius. Based on a detailed flow field, four out of the eleven vortices were found to be crucial in determining differences in the drag coefficient of the wheel and wheelhouse. Based on this analysis, an alternate wheelhouse geometry, combining the advantages of the two geometric configurations considered in this work, was proposed, that could potentially lead to a reduction in the drag coefficient of the vehicle.


A military need Fifteen years ago RT Porter gave us an account of some simple pieces of card developed in 1915-16 to assist in giving more precise references on the new squared maps being issued on the Western Front.1 These pieces of card – then simply described as a 'Reference Cards' – and their use are described in detail in an army pamphlet of December 1916 which stated: "To facilitate the use of coordinates on the maps, special cards have been prepared and issued. ... the cards [are] for the 1:20,000 and 1:10,000, and for the 1:100,000 scales."2 The pamphlet illustrates two such cards: one which can be used for the two larger scales, and another for 1:100K scale. I have never seen one of these cards, but from the images and description it is clear that two separate cards were being issued. The next appearance of the cards, as pointed out by RT Porter, was in the 1929 War Office Manual of Map Reading, Photo Reading, and Field Sketching where the cards are now called Romers – though this is placed in inverted commas as if the name is a new technical and unfamiliar term: so the heading reads: ''Romers'' or Reference Cards.3 Now in addition to the diagram of a standard British Romer4 there was a diagram of a metric Romer (numbered in cm, lines 1 mm apart) for use on the metric grids of continental maps, and there is guidance on various gridlines found on Belgian, French, Swiss, and German maps. The second Romer diagram with two sets of numbers (0-5 and 6-10) on each edge; the second set (610) for use with grid lines spaced 5km apart (see figure 1).5


The analysis of heart rate variability is discussed in relation to examination of patients under mental stress. This is an objective method, because it does not require any feedback or communications with the patients. Therefore, it does not cause the additional stress resulting from the examination itself. Such systems have potential applications in industrial medicine tests.<<ETX>>


Selective oxidation of primary alcohols to the corresponding aldehydes by potassium dichromate at room temperature under solvent-free conditions are described. This new procedure can also oxidise secondary alcohols.


Chapter 5 explores building classroom management techniques through the use of restorative practices, including how students, teachers, and staff members share the responsibility of managing issues and behavioral concerns within a classroom. The topic of finding a balance between focusing on academic content and integrating restorative practices into a classroom are also discussed. Finding a balance can sometimes mean that teachers and students must learn to be flexible within the classroom as the day's activities may need to shift in order to address an issue within the school. As the school community members learn to share the responsibility of managing the classroom, a change in roles can occur in which the teacher acts as a counselor, a counselor acts as a teacher, and a student acts as a teacher.


A theory of medium-energy (∼ keV) electrons and heavy ions in Jupiter's magnetosphere is presented. Lower hybrid waves are generated by the combined effects of a ring instability of neutral wind pickup ions and the modified two-stream instability associated with transport of cool Iogenic plasma. The quasi-linear energy diffusion coefficient for lower hybrid wave-particle interactions is evaluated, and several solutions to the diffusion equation are given. Calculations based on measured wave properties show that the noise modifies substantially the particle distribution functions. The effects are to accelerate superthermal ions and electrons to keV energies and to thermalize the pickup ions on time scales comparable to the particle residence time. The [S2+]/[S+] ratio at medium energies is a measure of the relative contribution from Iogenic thermal plasma and neutral wind ions, and this important quantity should be determined from future measurements. The theory also predicts a preferential acceleration of heavy ions with an acceleration time that scales inversely with the root of the ion mass. Electrons accelerated by the process contribute to further reionization of the neutral wind by electron impact, thus providing a possible confirmation of Alfven's critical velocity effect in the Jovian magnetosphere.


The objective of this research work was to carry out phytochemical screening, and to evaluate the in vitro effect of the hydroetanolic extract of bulbs of Ismene amancaes (Amancay) against Candida albicans. The hydroethanolic extract was obtained by means of 30 g of bulbs from Ismene amancaes (amancay), the district of Otuzco, province of Otuzco, department of La Libertad. Preliminary phytochemical screening was performed using the Martinez and Cuellar method. The hydroethanolic extract was fractionated in the chloroform, ethanolic and aqueous extract, and in which the different phytochemical tests were carried out. Finally the antifungal effect of the hydroquinhanolic extract of Ismene amancaes "amancay" was determined by means of the diffusion method in nightclubs - Kirby & Bauer at a rate of 0.05 g / ml, 0.10 g / ml, 0.15 g / ml, 0.30 g / ml and 0.5 g / ml against candida albicans. In the chloroformic fraction of bulbs of Ismene amancaes, triterpene-steroids are qualitatively identified. Phenolic compounds, alkaloids, amino acids, flavonoids, catechins and resins were qualitatively identified, and in the proportion of Ismene amancaes, alkaloids and saponins were qualitatively identified. The hydroethanolic extract of bulbs of Ismene amancaes "amancay" presented at concentrations of 0.15 g / ml, 0.30 g / ml and 0.5 g / ml halos of inhibition, with average values of 14.67 mm ± 2.5, 25.42 mm ± 1.62, 28.75 mm ± 3.11 respectively. Being sensitive to Candida albicans. The minimum antifungal concentration of the hydroethanolic extract of Ismene amancaes bulbs was 0.5 g / ml, compared to Candida albicans


Introduction The 'Arthropathy of Down syndrome' was first described in 1984. Three decades on we still have limited literature on the clinical and radiological features of this arthritis, despite the fact that it is thought to be 3-6 times more common than JIA in the general paediatric population. Down's Arthropathy (DA) is rarely recognised at onset, and remains under-diagnosed and largely under-reported in this population group. Ireland has one of the highest Trisomy 21 birth rates in Europe (1/547), & therefore provides an ideal setting for such a study. Research Q's 1. What are the clinical & radiological features of DA? 2. Is DA missed, leading to a delay in dx?


Despite theoretical differences between item response theory (IRT) and classical test theory (CTT), there is a lack of empirical knowledge about how, and to what extent, the IRT- and CTT-based item and person statistics behave differently. This study empirically examined the behaviors of the item and person statistics derived from these two measurement frameworks. The study focused on two issues: (a) What are the empirical relationships between IRT- and CTT-based item and person statistics? and (b) To what extent are the item statistics from IRT and those from CIT invariant across different participant samples? A large-scale statewide assessment database was used in the study. The findings indicate that the person and item statistics derived from the two measurement frameworks are quite comparable. The degree of invariance of item statistics across samples, usually considered as the theoretical superiority IRT models, also appeared to be similar for the two measurement fireworks.


In the article, some bilinear evolution equations in Hilbert space driven by paths of low regularity are considered and solved explicitly. The driving paths are scalar-valued and continuous, and they are assumed to have a finite $p$-th variation along a given sequence of partitions in the sense given by Cont and Perkowski \cite{ConPer18} ($p$ being an even positive integer). Typical functions that satisfy this condition are trajectories of the fractional Brownian motion of the Hurst parameter $H=\sfrac{1}{p}$. A strong solution to the bilinear problem is shown to exist if there is a solution to a certain temporally inhomogeneous initial value problem. Subsequently, sufficient conditions for the existence of the solution to this initial value problem are given. The abstract results are applied to several stochastic partial differential equations with multiplicative fractional noise, both of the parabolic and hyperbolic type, that are solved explicitly in a pathwise sense.


Work in the measure algebra of the Lebesgue measure on N2 : for comeagre many [A] the set of points x such that the density of x in A is not defined is Σ30 ‐complete; for some compact K the set of points x such that the density of x in K exists and it is different from 0 or 1 is Π30 ‐complete; the set of all [K] with K compact is Π30 ‐complete. There is a set (which can be taken to be open or closed) in R such that the density of any point is either 0 or 1 , or else undefined. Conversely, if a subset of Rn is such that the density exists at every point, then the value 1/2 is always attained on comeagre many points of the measurable frontier. On the route to these results we show that the Cantor space can be embedded in a measured Polish space in a measure‐preserving fashion.

ABSTRACT Compagnie Nationale du Rhône (CNR) has operated the Rhône River since 1934 according to three core missions – hydropower generation, inland navigation and irrigation – using 19 run of-river multi-purpose hydropower schemes. To ensure hydraulic safety and optimise hydro power production and commercialisation, CNR developed a range of hydrometeorological forecasting tools, currently run every day in real time by CNR forecasters. The first is an hourly deterministic tool, giving forecasts up to the next 4 days. This tool does not allow quantification of uncertainties, which is a key issue to improve forecasts and take better operational decisions. At the same time, national meteorological centres provide ensemble meteorological forecasts, and thus information about uncertainty. Therefore, CNR is developing a chain of ensemble forecasting tools based on ensemble meteorological forecasts and various post-processing methods. These tools provide hourly/daily hydrological forecasts up to the next 4/12 days. The operational use of such a probabilistic forecasting chain is intended to facilitate decision-making processes. All these tools have been designed to leave large room for human expertise. This paper presents the tools described above, but also their interaction with human forecasters as well as the first attempts to link them together to add consistency between the different forecast types.


A TiCN cermet composite coating was fabricated on 45# steel substrate by reaction nitrogen arc welding cladding technique. The mixture powder of titanium and graphite was preplaced onto the 45# steel substrate after intensive mixing by star ball-mill and gluing with starch binder. The microstructures and phase of the coatings, interracial behavior between coatings and the substrate were investigated by scanning electronic microscope, X-ray diffractometer. The microhardness distribution of the coating section, frictional coefficient, abrasion loss and wearing surface morphology were investigated by microhardness tester, abrasion machine and scanning electronic microscope. The results show that an excellent bonding between the coatings and the 45# steel substrate is ensured by the strong metallurgical interface and phase of the coatings are mainly composed of TiCN. The highest microhardness of the coatings reaches HV 0.5 810, which is about 3 times more than that of the 45# steel substrate. The anti-abrasive test results show the coating has better anti-abrasive performance than the 45# steel substrate.


Human infection with Sars CoV-2 named COVID-19 by WHO causes micro and macro vascular thrombosis which is one of the major complications along with Acute Respiratory Distress Syndrome (ARDS). Although the mechanisms involved are poorly understood but appear to consist of a cascade of inflammation with involvement of many inflammatory cytokines, coagulation factors and platelets and results in some kind of immune-thrombosis. The thrombotic and thrombo-embolic events have caused major morbidities and mortalities and have been topic of extensive research in present pandemic. Timely recognition of these events and intervention with anticoagulation has been the key to successful management of critically ill COVID-19 patients.

Surface roughness is primary measure of pavement performance that has been associated with ride quality and vehicle operating costs. Of all the surface roughness indicators, the International Roughness Index (IRI) is the most widely used. However, it is costly to measure IRI, and for this reason, certain road classes are excluded from IRI measurements at a network level. Higher levels of distresses are generally associated with higher roughness. However, for a given roughness level, pavement data typically exhibits a great deal of variability in the distress types, density, and severity. It is hypothesized that it is feasible to estimate the IRI of a pavement section given its distress types and their respective densities and severities. To investigate this hypothesis, this paper uses data from in-service pavements and machine learning methods to ascertain the extent to which IRI can be predicted given a set of pavement attributes. The results suggest that machine learning can be used reliably to estimate IRI based on the measured distress types and their respective densities and severities. The analysis also showed that IRI estimated this way depends on the pavement type and functional class. The paper also includes an exploratory section that addresses the reverse situation, that is, estimating the probability of pavement distress type distribution and occurrence severity/extent based on a given roughness level.


Search strategies based on random walk processes with long-tailed jump length distributions (Levy walks) on the one hand and intermittent behavior switching between local search and ballistic relocation phases on the other, have been previously shown to be beneficial in stochastic target finding problems. We here study a combination of both mechanisms: an intermittent process with Levy distributed relocations. We demonstrate how Levy distributed relocations reduce oversampling and thus further optimize the intermittent search strategy in the critical situation of rare targets.

The fluidization characteristics of a prototype-fluidized bed laboratory reactor were understudied in order to investigate the suitable conditions at which the dehydrogenation reaction of butane could be carried out. To achieve this, a reactor with an effective volume of 1100ml was fabricated and coupled with temperature and pressure accessories. Zeolites were obtained from the market and clay obtained from different sources and pre-treated was used as catalyst. Airflow at high velocity between 3000-7000ml/hr was used as the fluidising medium to obtain the bed characteristics while butane gas was used to obtain the dehydrogenation kinetics. The temperature of the reactor system was varied between 353K and 413K while maintaining constant pressure of 1.5 10 5 N/m 2 through a manifold gauge and a constant catalyst weight. Various methods such as pressure fluctuations, visual observations, and bed expansion were used to determine the transition velocity at which fluidization begins. It was observed that this depends on factors such as mean particle size, particle size distribution, and column diameter. The minimum fluidizing velocity obtained for zeolite was 0.0133m/s and 0.0102m/s for treated clay materials both for a particle size of 250µm. The conversion of butane over the catalysts showed an increase in both cases with a maximum at 0.9813 at 413K. This decreases as the reaction progresses.

The initial point for building this Neoclassical in spirit model is the standard IFPRI model presented in Lofgren, Lee Harris, and Robinson (2002) which ultimately is the Computable General Equilibrium model applied at the Macroeconomic and Trade Division (TMD) at the IFPRI itself. It follows the neoclassicalstructuralist modelling tradition referable to Dervis et al. (1982). However, because these models are mainly applied for developing countries, the IFPRI researchers have added many features that characterize these economies, i.e. the presence of a fraction of total production which not enter the market but is self(home) consumed and an explicit treatment of marketing and transportation costs (transaction margins) both in the inner and in the foreign markets. To implement it a SAM is required. It should have the format of the one presented in appendix A. In this way the IFPRI model may summarize and explain each accounting relation. More generally, as Pyatt (1988) states: "A SAM is not a model" however "SAMs and models are intimately related and that making this relationship explicit is potentially useful for model construction and analysis". Here, we consider a countryspecific case of this model's application and we describe in details the Mozambican CGE with its main features, and then we present its implementation in GAMS/MPSGE. In fact, this class of models is mainly applied as NonLinear problems but in this context we present it as a Mixed Complementarity problem. Although we follow the standard framework, the application in MPSGE and some values restrictions modify the formal presentation of the model itself.


Neutron diffraction has been used to show that the magnetic moment vector in the antiferromagnet HoSb changes direction as a function of temperature below TN=5.7K. The experimental results are in qualitative agreement with a recent theoretical prediction by Jensen et al. (1980) which ascribe the changing directions to a competition between the crystal fields and the dipolar interactions.


I. Riemannian geometry of multidimensional Poisson brackets of hydrodynamic type. In [1] we developed the Hamiltonian formalism of general onedimensional systems of hydrodynamic type. Now suppose that a system of the type of an ideal fluid (possibly with internal degrees of freedom) is described by a set of field variables u = (u(x)), i = 1, . . . , N , in a space with coordinates x = (x), α = 1, . . . , n. The equations of motion of this system have the form of first order equations, linear in the derivatives:


This article is intended to examine the nature of urban expansion and development from a land speculation and urban sprawl perspective. Survey and case study approach were used to achieve this aim. As urban territory extends into adjacent periurban areas, speculators keep their land out of the current market so that developers of land and buildings must bypass it and home buyers should travel further distance to buy new lands and houses. This extra distance creates additional costs by increasing the cost of development, operation and travel. The finding of this article concludes that the speculators who held their land out off the market and received an average land value increase of about $230 per m2 each year generated extra social costs which they did not pay about $1,810 per m2 each year.


Learning practical skills especially in fields of medical science is significantly important. There are controversies over the effectiveness of teaching methods, though. It is believed that some of these teaching methods cause learning to speed up, facilitate, and cost less. Therefore, the present study is aimed at comparing the effects of traditional and combined teaching methods on freshman nursing students' learning skills of wound care in academic year of 2009-2010. Materials and Methods: The present experimental study was consisted of 42 nursing students admitted to university in 2009-2010. They were randomized (every other student) into two groups, firstand secondhalf year students, by the education head office. Combined and traditional teaching methods were respectively utilized to teach the experimental and control groups skills of wound care. Data collection was conducted through a questionnaire and a bandage skill checklist. Cognitive domain and psychomotor effects were statistically analyzed through a multiple-choice test and OSCE, respectively. Findings: Statistical results proved a significant difference between the experimental group and the control one regarding their cognitive skill (Chi-square with p<0.05 and t=3.14) and psychomotor skill (p<0.05 and t=5.23). Conclusion: Compared to traditional method, combined teaching method has greater effect on practical bandage skill especially in psychomotor domain. Therefore, it is highly recommended that this method of teaching should be used for other skills, in other majors, and at other universities of the country.

June 2, 2009 PARTICIPATION, DEMOCRACY AND HUMAN RIGHTS An approach based on the dilemmas facing Latin America José Thompson Director, Center for Electoral Promotion and Assistance Inter-American Institute of Human Rights San Jose, Costa Rica This paper will analyze the relationship between democracy and human rights, with an emphasis on the many faces of political participation. It will then take a look at recent conditions in Latin America in these areas in order to frame a modern-day approach to the implications of the complex nature of human rights and their potential as a tool to assess quality and strength of democracy. The connection between democracy and human rights Many attempts have been made to identify the ways in which respect for human rights is associated with a healthy democracy. Nevertheless, relationships that have been described between the two concepts and their applicability tend to be based mostly on assumption, without focusing on concrete cases taken from recent history. The relationship between the two concepts – human rights and democracy – can be seen from various perspectives. For the purposes of this paper, we maintain that the use of

Results
The prescriptions including Angelicae Sinensis Radix were commonly used to treat stomach-ache, arthralgia syndrome, irregular menstruation and other syndromes. The highest frequency used drugs were Radix Paeoniae Rubra, Radix Paeoniae Alba, Radix Salviae Miltiorrhizae, Pericarpium Citri Reticulatae, Rhizoma Cyperi, and so on. The most frequency drug combinations were "Angelicae Sinensis Radix, Radix Paeoniae Rubra", "Radix Paeoniae Alba, Angelicae Sinensis Radix", and "Radix Salviae Miltiorrhizae, Angelicae Sinensis Radix". The drug association rules that the confidence was more than 0.9 were "Fructus Jujubae-Angelicae Sinensis Radix", "Fructus Amomi Villosi-Angelicae Sinensis Radix", "Radix Codonopsis-Angelicae Sinensis Radix", and "Os Draconis-Concha Ostreae", and so on.

Conclusion
The drugs in the prescriptions containing Angelicae Sinensis Radix that built by Pro. Yan mostly had the effects of cooling blood, replenishing blood, and promoting blood circulation for removing blood stasis, which reflected the clear thought when making prescriptions.

- - The present investigation aims to analyze and compare the performance of a photovoltaic-powered submersible pump under three various climatic conditions in Egypt. The pump is employed to irrigate wheat and maize crops in a one-feddan farm by adopting the actual well depth and crop water requirement in the proposed locations. Furthermore, the total power of solar modules required to operate this pump is computed to reveal the auxiliary power needed for these crops at the proposed locations during their irrigation season. At the introduced weather conditions, an economic analysis is conducted to examine the feasibility of the solar powered pump versus that operated by traditional diesel generator. The results reveal that the net generated power via the PV panels to operate a pump used to irrigate wheat crop is 325, 495 and 17 kW and for maize crop is 1786, 1767 and 266 kW in Aswan, Alexandria and Giza cities, respectively. In Alexandria, Giza, and Aswan cities, utilizing solar PV panels as a power source for the pump used to irrigate wheat crop has proven its economic feasibility as it is expected to dramatically reduce the total cost by around 49, 46, and 76%, respectively and for maize crop cost is reduced by 47, 48 and 66% in the same locations compared to diesel generators.


Background: Parkinson's disease (PD) is a progressive neurodegenerative motor disorder. However, non-motor complications frequently alter the course of the disease. A particularly disabling non-motor symptom is dementia. Methods/Design: The study is designed as a multicentre prospective, observational cohort study of about 700 PD patients aged 45–80 years with or without dementia and PD-mild cognitive impairment (MCI). The patients will be recruited in eight specialized movement disorder clinics and will be followed for 36 months. Information about the patients' functional status will be assessed at baseline and 6-/12- month intervals. In addition, 120 patients with dementia with Lewy bodies (DLB) will be included. Well-established standardized questionnaires/tests will be applied for detailed neuropsychological assessment. In addition, patients will be asked to participate in modules including volumetric MRI, genetic parameters, and neuropsychology to detect risk factors, early diagnostic biomarkers and predictors for dementia in PD. Results: The study included 604 PD patients by March 2011; 56.3% were classified as having PD alone, with 30.6% of patients suffering from PD-MCI and 13.1% from PD with dementia. The mean age of the cohort was 68.6 ± 7.9 years, with a mean disease duration of 6.8 ± 5.4 years. There was a preponderance of patients in the earlier Hoehn and Yahr stages. Conclusion: The main aim of the study is to characterize the natural progression of cognitive impairment in PD and to identify factors which contribute to the evolution and/or progression of the cognitive impairment. To accomplish this aim we established a large cohort of PD patients without cognitive dysfunction, PD patients with MCI, and PD patients with dementia, to characterize these patients in a standardized manner, using imaging (serial structural MRI), genetic and proteomic methods in order to improve our understanding of the course of the PD process and the development of cognitive dysfunction and dementia in this disease. The inclusion of the DLB patients will start in the second quarter of 2011 in the BMBF-funded follow-up project LANDSCAPE.


Purpose
Employee engagement literature pertaining to professional salespeople has revealed several antecedents and consequences that lead to greater performance and turnover reduction. However, engagement literature in the field of human resource development (HRD) does not account for Generation Z (Gen Z), the latest in the workforce who has been noted to be vastly different from previous generations. This study aims to explore how to engage Gen Z in the context of professional selling by identifying the antecedents and consequences of employee engagement based on individual characteristics and organizational needs of this group.

Design/methodology/approach
A systematic literature review was conducted. In total, 21 papers relevant to employee engagement, professional selling and Gen Z were critically analyzed.

Findings
Findings indicate that Gen Z's organizational need for mentoring and their individual characteristic of wanting job control and ownership are vital antecedents that could increase employee engagement. In addition, competitive rewards are important consequences that could improve individual sales performance.

Practical implications
HRD practitioners and organizational leaders must understand the unique characteristics of Gen Z to effectively engage them in the workplace. For sales organizations, there is a critical need to offer mentoring opportunities and competitive rewards from the start of Gen Z salespeople's employment.

Originality/value
This research expands current engagement literature by addressing an emerging, under-explored issue – how to engage the newest workforce, Gen Z, in the context of professional selling.


During the winter crop season in 2016 a very high incidence of viruslike symptoms of mosaic, leaf curling and deformation, and plant dwarfing was reported by farmers in central areas of Brazil. Bean plants were collected in commercial farms in Luziânia, Cristalina and experimental plots in Goiânia and Brasilia.


In this article we attempt at providing evolution of the resource consumption (RC) which meets the needs of a modern society. In analyzing the impact of resources consumption and technologies to meets the needs, over the possibility of anticipating the future is necessary to establish patterns based on past information. On the those information, we can say that RC evolution between the ? and ? moments follows a logistic curve. Based on the graphic representation of the RC evolution, we can identify four different phases, with specific characteristics. Each phase will be the basis for building a pattern of RC evolution. For each of the four patterns we analytically present the risks of performing an exercise of future's anticipation. The analysis indicates that currently, the forecasts lose representativeness and becomes less important compared with the foresight. The foresight, through its features, answers much better the needs to anticipate the future evolution of the society, compared to the forecast. Foresight exercises are offensive compared to the defensive nature of forecast exercises. The foresight exercise specialist is not just a spectator to the evolution of the phenomenon, as in the forecast's case, but is involved in making and implementing decisions. Foresight exercises, although not able to generate accurate projections of the future, will help to correlate the current technologies with the future needs of society


The collection of Coccinellidae from Cuban Natural History National Museum was not organized and only three species were identified. With a work of curatoria 266 coccinelid specimens were quantified with a satisfactory conservation estate which arose from collets realized between 1928 and 2006. Another 18 species were possible identified, so scientific value of collection was incremented, while 16 specimens were groped in 11 morfo-species. Those species better represented were Brachiacantha decora Casey, Cycloneda sanguinea limbifer Casey and Arawana cubensis (Dimmock). The data base with the information of specimens stored in coccinelid collection hold 228 records with diverse information about genera, species, locality, province and collect date.


Despite the advancement in the mathematical models for solving and modeling marketing problems, there exists gap between model predictions and market reality. Fuzzy logic bridges this gap by providing marketers with the opportunity of combining robust human experts in the form of linguistic rules to formulate a knowledge-base. These rules are systematically developed into a marketing tool which provides intelligent pricing decision support for marketers in a dynamic and competitive environment. In this paper, these expert pricing systems which are designed and developed to help businesses in pricing decision-making are examined. Price-Strat, FuzzyPrice, and exPrice expert pricing systems are compared and discussed. These three expert pricing systems are explored along with their fuzzy development approach, effectiveness, and attributes in pricing products and services.


Objective To valuate the three-dimensional CT angiography(3DCTA) in diagnosing blood vessel diseases.Methods CTA findings of 284 patients confirmed with blood vessel diseases were retrospectively analyzed.They were divided into two groups:141 cases of head and neck and 143 cases of trunk and extremities.Scan was performed with the beam collimation of 0.625 ~ 3.0mm,increment of 0.3 ~ 1.4mm,pitch of 1.0 ~ 1.5,with the gross contrast medium of 1.5 ~ 2.0ml/kg.3D imaging methods included volume rendering(VR),multi-planar reformatting (MPR),curved planar reformatting(CPR),surface shade display(SSD),maximum intensity project(MIP) and virtual endoscopy(VE).The diagnostic results of CTA were compared with those of DSA and/or surgery.Results In this study,3D images of vasculature met the diagnostic criterion.The diagnostic sensitivity,specificity and accuracy of CTA was 97.28%,82.35% and 96.48%,respectively.The size of artery aneurysm shown with CTA and DSA had no significant difference( P >0.05 ),both smaller than that in surgery( P < 0.05 ).Conclusion 3DCTA could be used in diagnosing the cardiovascular diseases and compensate the limitation of conventional CT.It had the characteristics of non-invasion,high accuracy and could partly substitute DSA.

Continual or lifelong learning (CL) is one of the most challenging problems in machine learning. In this paradigm, a system must learn new tasks, contexts, or data without forgetting previously learned information. We present a scalable approach to multi-context continual learning (MCCL) in which we decouple how a system learns to solve new tasks (i.e., acquires skills) from how it stores them. Our approach leverages two types of artificial networks: (1) a set of reusable, \textit{task-specific networks} (TN) that can be trained as needed to learn new skills, and (2) a lifelong, \textit{autoencoder network} (EN) that stores all learned skills in a compact, latent space. To learn a new skill, we first train a TN using conventional backpropagation, thus placing no restrictions on the system's ability to encode the new task. We then incorporate the newly learned skill into the latent space by first recalling previously learned skills using our EN and then retraining it on both the new and recalled skills. Our approach can efficiently store an arbitrary number of skills without compromising previously learned information because each skill is stored as a separate latent vector. Whenever a particular skill is needed, we recall the necessary weights using our EN and then load them into the corresponding TN. Experiments on the MNIST and CIFAR datasets show that we can continually learn new skills without compromising the performance of existing skills. To the best of our knowledge, we are the first to demonstrate the feasibility of encoding entire networks in order to facilitate efficient continual learning.


The urethral protractor is a new device that helps push the urethral stump upwards together with the urogenital diaphragma. It facilitates suturing the anastomosis in radical prostatectomy and the intestino-urethral anastomosis after cystectomy. With the help of the urethral protractor, the urethral stump can be directed into various positions in order to simplify the localization and control of bleeding close to the urethra. By tilting the urethral protractor to one side, damage to the neurovascular bundles can be avoided when suturing. The urethral protractor consists of a rigid, reusable, suture guide made of stainless steel and a special, disposable balloon catheter.


This retrospective study shows a significant correlation between middle ear fluid and sinusitis in children. Sinus films were obtained on 70% of 166 consecutive patients receiving myringotomy and tubes. Antral irrigations were performed when radiographic findings of sinus disease were present. The need to evaluate sinus disease in children requiring indwelling ventilation tubes is stressed.

A general class of discrete, nonlinear renewal equations containing a real parameter is studied. Bifurcation theory methods are used to prove the existence of nontrivial periodic solutions and asymptotically periodic solutions. Fundamental to the approach is the "limit equation" whose periodic solutions are shown to be asymptotic limits of solutions of the renewal equation. An application is made to a model of age-structured population dynamics in which the bifurcation of nontrivial equilibria and 2-cycles is shown to occur with increasing inherent net reproductive value.


Psychoneuroendocrineimmunology (PNEI) brings together knowledge acquired since the 1930s from endocrinology, immunology, neuroscience, and psychology. With PNEI, a model of research and interpretation of health and disease is emerging, which sees the human body as a structured and interconnected unit, where the psychological and biological systems are mutually coordinated. In the PNEI view, many factors could influence mental health, with the endocrine system involved in mediating the effects of environmental stress on mental health and inflammation in the onset and course of psychiatric disorders as a result of individual and collective conditions and behaviors. Among these, nutrition is one way by which the environment impacts physiology: indeed, many pieces of research showed that several elements (e.g., probiotics, fish oil, zinc) have a positive effect on mental disorders thus being potentially augmentation agents in treatment. Still, physical activity can moderate depressive symptoms, while prolonged stress increases the risk of psychopathology. Taken together, the PNEI-based approach may inform prevention and treatment strategies, also in the field of mental health care.


In a May 3 memo, the GOP "Family Caucus" presented its legislative agenda for the remainder of the 104th Congress. Chaired by Representative Tom Coburn (R-OK), the anti-choice caucus promotes family and social issues, and emphasizes religious liberty and parental rights. It is seeking to eliminate funding for Title X of the Public Health Service Act, which provides grants to domestic family planning providers; repeal the Freedom of Access to Clinic Entrances Act (FACE); curtail fetal tissue research; restrict the production and sale of RU486; reduce funding for the US Agency for International Development (USAID); and hinder US representation at the UN Fourth World Conference on Women. On May 17, the Virginia-based Christian Coalition unveiled a ten-point "Contract with the American Family," which targets reproductive health care by restricting late-term abortions, reversing the Medicaid requirement that states cover abortions in cases of rape or incest, and eliminating funding for Title X and international family planning. Director Ralph Reed was joined at the group's press conference in the Capitol by Speaker of the House Newt Gingrich (R-GA) and Senator Phil Gramm (R-TX), both of whom are anti-abortion. Senate Majority Leader Robert Dole (R-KS), who is also anti-choice, met with Reed in his office later that day. Anti-choice representatives and senators met with some success in the last month in restricting US funding for family planning programs abroad, US participation in international meetings, and the performance of abortions at military facilities. Representative Charles Canady (R-FL) has introduced a bill banning modified dilation and evacuation abortions, and Representative Robert Dornan (R-CA) has introduced the "Family Planning Programs Repeal Act" (HR 1623).


The goal of this diploma thesis is to give an overview of data security in cloud systems. The first part covers basics of cloud and security. Additionally it identifies some risks arising from the use of cloud computing. The second part focuses on cryptography, especially on ciphers, as a tool for mitigation of those risks. We try to convey some recent ideas (especially those interesting in the context of cloud computing) from the cryptographic world to the reader in an easy manner. We conclude with some tips on how to ensure security of data.


Substituted nickel zinc ferrites have been prepared in the composition series Ni 0.5 Zn 0.5 Bi x Fe 2.0- x O 4 with x having values in the range 0.05–0.2. The electrical conductivity of the samples has been measured over the temperature range 150 to 300 K at frequencies ranging from 1 kHz to 1 MHz. The ac conductivity shows a variation of ω s where ω is the angular frequency and s is an exponent having values in the range 0.6 to 0.8. Correlated barrier hopping model is found to be satisfactory in explaining the conductivity which arises due to the presence of Fe 2+ ions. The latter are created because a substantial amount of Bi 3+ gets oxidized to the Bi 5+ state.


Students of work processes have increasingly debated the likely emergence of a flexible, "post-Fordist" pattern of work organization within advanced capitalist manufacturing industries. This paper uses qualitative methods to address the debate over post-Fordism, hoping to bring to light certain neglected aspects ofshopfloor relations that bear upon the transformation of work. The study focuses on the changes that have occurred at four manufacturing plants in the pulp and paper industry located in diverse regions of the United States. Despite abundant opportunities for the redesign of manual workers' jobs, these mills provide only partial support for post-Fordist theory: The skills demanded of manual workers have indeed risen, as post-Fordists expect, but we find little indication of any expansion of craft discretion, nor of any nascent synthesis of mental and manual labor. Instead, we find trends toward the increasing centrality of process engineers within the labor process, a heightening of the barrier between expert and non-expert labor, and the symbolic devaluation of craft knowledge — in short, strong indications that Fordist principles of work organization have remained quite prevalent. The paper concludes by discussing the social and organizational factors that explain the tenacity of Fordism and that seem likely to obstruct the pursuit of workplace flexibility within U.S. manufacturing.


ABSTRACT This paper presents numerical solutions for determining the uplift capacity of strip plate anchors embedded at different positions either from the toe or crest of cohesive-frictional soil slope. Finite element method based on lower bound theorem of limit analysis in combination with second-order cone programming has been used for obtaining the solutions. Dimensionless uplift factors are used for estimating the ultimate uplift resistance of anchors due to contribution of cohesion, unit weight and angle of internal friction of soil. For different edge-distance of anchor either from the crest or toe of the slope, computations are carried out for different combinations of internal friction angle of soil, angle and height of sloping surface, normalised strength of soil, and embedment ratio of anchors. The uplift capacity has been found to remain the same within a zone extending from the middle of the slope towards both toe and crest of sloping ground.

A significantly increased frequency of chromosomal aberrations was found among workers at a sulphite pulp factory in northern Sweden. This increase was found to be associated mainly with exposure to sulphur dioxide (boiling of sulphite pulp and handling of sulphuric acid), and not with exposure to chlorine and dust in other workplaces within the factory.


This ARI discusses the current crisis in US-Pakistan relations and analyses the interaction between Washington and Islamabad since the events of 9/11.

In the wake of Osama bin Laden's killing, relations between the US and Pakistan have deteriorated. Islamabad has reduced military and intelligence cooperation and demanded an end to drone attacks. In Washington, members of Congress have sharply criticised Pakistan's ambiguous stance towards terrorist groups. The Obama Administration has suspended the disbursement of US$800 million of military aid. Just before retiring as Defense Secretary, Robert Gates described US-Pakistan relations as a bad marriage. Does this mean that the two countries are headed for a messy divorce? I think not. The US and Pakistan need each other too much for that to happen. Relations are likely to continue to rock along as they have ever since Pakistan and the US became allies in 1954.


The aim of this study was to investigate the effect of cognitive?behavioral group therapy (CBGT) on social
anxiety disorder using latent growth model (LGM) to estimate average growth trajectories and individual
differences in longitudinal treatment outcomes. LGM is able to deal with missing data using full-information
maximum-likelihood (FIML) estimation. We analyzed piecewise latent growth for nonlinear growth functions
to examine changes during treatment and post-treatment. Our CBGT involved Korean culture-specific
variations in classical CBGT during weekly 2-hour sessions over the course of 8 weeks. We assessed 36
patients with social anxiety disorder using Liebowitz Social Anxiety Scale and a brief version of the Fear of
Negative Evaluation Scale on five occasions (baseline, 4 weeks, 8 weeks, 4-week follow up, and 8-week
follow up). As expected, social anxiety and avoidance decreased significantly during treatment periods.
Fear of negative evaluation decreased significantly both during treatment and post-treatment. We could
delicately explain individual differences in treatment effect with LGM. This study demonstrated the efficacy
of CBGT for social anxiety disorder and the feasibility of using LGM to analyze repeated measures of data
on clinical treatment, and longitudinal studies examining treatment effect could use LGM in the future.


1. Two cuts, the leg and the loin, were taken from the right sides of 102 pig carcasses. Their densities were determined by weighing in air and in water and the cuts were dissected into fat, muscle, bone, skin and connective tissue. Samples of the muscular and fatty tissues were taken to obtain a measure of the analytically determined fat content. The weights of each tissue were expressed as a percentage of the weight of each cut and related to density by the methods of correlation and regression. Correlation coefficients and regression equations were calculated separately for legs, loins and the composite leg plus loin for each pig and for legs and loins rogarded as 204 separate pieces of pig carcass. 2. Correlations and regressions were used to relate the composition of the loin cut to three measurements of backfat thickness taken over the eye muscle at the level of the last rib, and to eye muscle area. These allowed a comparison of density and backfat thickness as measures of the fat and lean content of the loin cuts. 3. There was evidence of a high degree of association between the fat or muscle contents of the cuts and the density or the reciprocal of density. In no case was the simple correlation coefficient between muscle and density or fat and density less than 0·84. The greatest standard error of estimate of any of the regressions of porcentage fat or percentage muscle on density was 3·3% fat, for the regression of percentage separable fat on the reciprocal of the density of the loin cuts. Density was found to be a better measure of the muscle or fat content of the loin cuts than eye muscle area or any of 3 measurements of backfat thickness taken over the eye muscle. 4. Dissection data from 25 whole sides supported these results showing a high correlation between density and percentage fat or percentage muscle. 5. There was a low correlation, r = 0·41, between percentage bone and density of 102 leg cuts. That between density and percentage bone of 25 whole sides was r = 0·47; suggesting that bone content has but a small influence on carcass density. 6. It is suggested that carcass density is a better measure of carcass fatness or leanness than measurements of backfat thickness or eye muscle area.


Diamond films have been synthesized by LCVD through combined effect of ultraviolet XeCl laser and infrared CO2 laser. The substrates are Si wafers. A special apparatus has been developed. The deposition conditions have been studied. Raman spectra of the films show a well-defined sharp peak at 1332cm-1 which is the characteristic of diamond. The morphology of diamond crystal of the films is very clear under SEM. It has been confirmed that the films are of high pure diamond. The threshod deposition temperature is 340t. The roles of each laser are discussed.


The paper considers alternative methods of activation of cement systems based on the use of internal properties of cement. Their peculiarity is the use of activated cement and changing the sequence of mixing of cement mortar. Mixing of the main volume of Portland cement with cement slurry and its prior curing for 15 minutes allowed increasing the strength characteristics of hardened cement paste. As shown by experimental studies, the strength of the samples increases by 10–30% depending on the method of preparation and curing time of the cement slurry. Further experiments will be aimed at researching "activated cement–activated water" system.


Ernest Gaines's A Gathering of Old Men (1983) takes place in the late 1970s on the land of the Marshall plantation, a remote, unreconstructed spot in rural Louisiana. The novel tells the story of a group of humble African American elders who, for the first time in their lives, have resolved to stand up to their white oppressors. What makes Gathering vivid and compelling is Gaines's use of a variety of theatrical conventions to dramatize a simple story of revenge against a backdrop of enduring racial oppression. The first part of this essay shows that Gathering, while organized according to standard dramatic conventions, is also a celebration of African American vernacular and rhetoric as tools for subverting authority. This emphasis on verbal performance, the systematic questioning of everyday reality, as well as the choric outlook of the group of old men, narrows the focus of this essay from theatricality to tragedy. As Gaines once acknowledged, "the sense of Greek tragedy ... keeps coming back in my writing" (qtd in Lowe 30), and the second part of this essay further explores the influence of Greek tragedy on Gaines's work. While this section brings into light the elements of Greek tragedy that characterize the novel, it also argues that the ethics of Greek tragedy are better suited than modern literary conventions and contemporary moral values to convey the idiosyncrasies of the black experience in the deep South. Ultimately, Gathering is anything but what a slapdash review once called "a Louisiana pageant of calamity" and a "morality play" (Price 15). The novel highlights the complexity of the social and racial equation in 1970s Louisiana, provides a more acute understanding of past and present realities, and challenges the widespread and complacent notion that change is impossible. Theatrical Characteristics in Gathering Tragedy is a crisis ... in the wake of which no one among the heroes is the same as before. --Pierre Vidal-Naquet, Le miroir Brise (1) The opening scene of Gathering is deceptively simple: Beau Boutan, a Cajun farmer, has been shot dead in front of the cabin of Mathu, a solitary, charismatic African American elder. The back story to this simple murder, however, is really what Gathering is all about: the murder of a white man by a black man immediately exacerbates the racial tensions that saturate the fragile social mosaic of this isolated southern locality that has remained unchanged by the reforms of the civil rights movement. Choosing not to "crawl under the bed like [they] used to" (28), the old men have gathered in Mathu's yard where they brace themselves for the showdown with Fix Boutan, the father of the victim. There is no doubt in the minds of the hoary old lot that Fix, notorious for his bigotry and cruelty against black people, will show up to avenge the murder of his son. Everything designates Mathu as the culprit, but each old man has come to Mathu's with a gun loaded with one empty number-five shell similar to the one that killed Beau. When Sheriff Mapes gets there to arrest Mathu, each and every man stands before Mapes and claims, "I did it." The originality of Gathering derives in part from its multiple-perspective narration, in which all kinds of individuals--white and black, male and female, old and young, and rich and poor--have something to say about the murder of Beau Boutan. Sometimes complementary, sometimes discordant, the voices in Gathering are often organized in dialogues that, along with other forms of communication (gazes, silences, and body language), contribute to make Gathering a theatrical novel. Gathering also resembles a play as it observes the three unities of time, place, and action. (2) The story takes place in one day, from the killing of Beau Boutan to the final shootout. Almost everything happens in one place: Mathu's yard. Finally, the story follows the standard formula whereby theatrical action is organized according to (1) exposition--the murder of Beau; (2) complication--the armed old men hope for a deadly showdown with Fix and his clan; (3) crisis--Fix won't show up; Big Charlie (the actual murderer) decides to surrender but xenophobic Luke Will shows up, and a shootout ensues; and (4) resolution--Luke Will and Big Charlie die. …


Two different determinations have been made of the atomic arrangement in crystals of (NHi)2CuCli • 2 H20. Both are in qualitative agreement with the available photographic data and it has seemed important to ascertain whether a series of quantitative spcctrometric measurements would lead to a satisfactory choice between them. The essential difference between the two arrangements lies in the position of the chlorine atoms. Both are developed from the holohedral tetragonal space group Z)^ and have atoms of their two molecule cells in the following special positions):


PGC‐1α expression is a tissue‐specific regulatory feature that is extremely relevant to diabetes. Several studies have shown that PGC‐1α activity is atypically activated in the liver of diabetic rodents and contributes to hepatic glucose production. PGC‐1α and Foxo1 can physically interact with one another and represent an important signal transduction pathway that governs the synthesis of glucose in the liver. However, the effect of physical activity on PGC‐1α/Foxo1 association is unknown. Here we investigate the expression of PGC‐1α and the association of PGC‐1α/Foxo1 in the liver of diet‐induced obese rats after acute exercise. Wistar rats swam for two 3 h‐long bouts, separated by a 45 min rest period. Eight hours after the acute exercise protocol, the rats were submitted to an insulin tolerance test (ITT) and biochemical and molecular analysis. Results demonstrate that acute exercise improved insulin signalling, increasing insulin‐stimulated Akt and Foxo1 phosphorylation and decreasing PGC‐1α expression and PGC‐1α/Foxo1 interaction in the liver of diet‐induced obesity rats under fasting conditions. These phenomena are accompanied by a reduction in the expression of gluconeogenesis genes, such as phosphoenolpyruvate carboxykinase (PEPCK) and glucose‐6‐phosphate (G6Pase). Thus, these results provide new insights into the mechanism by which exercise could improve fasting hyperglycaemia.

Objective To investigate the association between the miR-137 gene polymorphisms and the dose for warfarin individual maintenance.Methods Blood samples were collected from 128 patients with stable warfarin dose requirements.Polymorphisms of miR-137 rs1625579 and VKORC1-1639AG(rs9923231) were detected by direct sequencing.The warfarin maintenance doses were compared between patients with different genotypes.Results In total of 128 patients,the mutation frequency of miR-137 rs1625579 was AA 85.2% and AC 14.8%.The warfarin dose of group AA was slightly higher than that of group AC,but the difference of the warfarin doses among the two groups did not reach statistical significance(P0.05).There was no significant difference as well in the mean stable dosage between patients of miR-137 rs1625579 AA and AC group in the patients with the same VKORC1 genotype.Conclusion miR-137 rs1625579 polymorphism may be not a major genetic factor that influences the individual dose for warfarin maintenance.


The point‐input admittance to a structure governs the input power and the local response to a point force. The average value and variation of this power and response have been computed on the basis of a simple statistical model of the structure. This is done by calculating the average values and standard deviation of the real part and the square of the modulus of the admittance at a single frequency and over bands of noise. The results are applied to the estimation of power flow into and response of a flat plate. Confidence levels for the estimates are obtained by assuming a form for the distribution of the admittance function. The paper is concluded by a discussion of the adequacy of the statistical model and possible applications of the results. [This research has been sponsored by the U. S.

Hilary Perraton's review of distance education throughout the developing world is the subject of this book. Founding director of the International Research Foundation for Open Learning, Perraton presents us with a good discussion of the social, technological, political, and economic aspects of distance education in the last 30 years. His well-framed contextual evidence makes this mandatory reading for those interested in open and distance learning in the third world. This book clearly delineates the parameters under which the reader is expected to understand arguments made. For example, Perraton's explanations of efficiency and cost include comparisons and contrasts to enrollments and overall expenditure (parameter a). The concept of efficiency becomes more difficult to articulate when one looks at enrollments and investments in relation to the completion rate of students (parameter b). The work offers practical information for comparing and understanding distance education in specific contexts, thus making solid arguments based on available data. Many parts of this text illustrate this point, such as the concluding suggestion that, where available in the developing world, distance education has positioned itself better at the tertiary level than at the secondary.


The paper presents the results of a study of the process of additive surface shaping by an electric arc in a protective gas. An analysis was made of the errors in the shape of surfaces obtained with different filling of layers. It has been experimentally confirmed that such process parameters as the orientation of the layers, the coefficient of their overlap are significant and affect the numerical value of the error in the shape of the resulting surface. In this connection, they should be taken into account when designing algorithms for dividing into layers and filling them with additive shaping by an electric arc in a protective gas.

. The article provides a detailed account and elucidation of Karl Popper's solution to Hume's problem of induction. It is pointed out that the solution has two major aspects. The first, explicitly described by Popper as his solution to the problem of induction, is the replacement of the inductivist account of the development of empirical knowledge, according to which cogniti- on begins with observations of particular events and proceeds through inductive inferences to certainly true or highly probable theories-generalisations, with the hypothetico-deductivist account, according to which cognition begins with a problem and proceeds through conjecturing its possible solutions (advancing hypotheses) and attempts to falsify them by reproducible results of observati-ons/experiments. The second aspect has to do with the problem of justification of the hypothetico-deductivist account (which replaces Hume's problem of the justification of induction). This problem is shown to be dealt with within Popper's-Bartley's general solution to the problem of justification, usually described as «non-justificationism», which admits the impossibility of absolute definitive justification (for any position) and replaces the search for such justification with the evaluation of relative advantages/disadvantages of competi- ng approaches, which can provide us with reasons to prefer or tentatively accept one of them. The comparison is made between Popper's hypothetico- deductivist account and Charles Pierce's account based on abduction, or inference to the best explanation. It is shown that these accounts has similar logical structures, that with respect to empirical science they suggest mutual corrections and clarifications, and that inference to the best explanation can provide justification for the assumption of the existence of laws of nature, which is implicit in the hypothetico-deductivist account.


ABSTRACT Precipitation data for Macomb (Illinois) for the period 1912-1981 were the bases for developing classroom exercises that offered college studcnts experience in collecting such data. After students collected the data, they reduced them to manageable proportions, and then examined average longterm relations which may have emerged among yearly, monthly, and daily values. This approach makes the study of weather and climate more relevant to students by utilizing local sources of data that students may find appealing and informative. Examples of the many figures, questions, and discussion topics that can be used in exercises to help students reflect on how the climate and weather conditions influenced tie precipitation patterns are presented_ For example, to get a concise summary of the general precipitation pattern in their community, the students placed on a graph yearly precipitation values for the entire period of record. To examine possible precipitation trends, students calculated a 5-year running mean for theMacombdata. The resulting graph helped to smooth the yearly fluctuations evident in their initial graph of yearly precipitation values, making the interpretation of dry and wet periods easier. (RM)


The focus of this article is the role that Christian ethics can play through the curricula of higher education institutions to combat the moral decline of society. The author reasons that there can be no such thing as neutral ethics and that every ethical belief is influenced by for instance religion, culture and circumstances. Ethics in the framework of post-modernism are thus disapproved of. This article shows that by integrating ethics in the curriculum, students as prospective employees and employers are prepared to live ethical. Finally an agenda is proposed of how ethical questions can be reflected therein. Failure to perform, be a team player and avoid gross transgressions such as stealing, lying, or drinking on the job was hazardous. Poor performance was the surest way of earning discipline. In contrast, unethical behaviour was rarely mentioned … Ethics was a matter of exit, rather than loyalty or voice (Badaracco & Webb 1995:13).

FIELD: textiles, paper. SUBSTANCE: method comprises measuring the density of washing liquid in g/cm 3 with simultaneous measurement of the temperature of the test solution in the washing unit bath, followed by subsequent determination using triaxial nomogram on density in g/cm 3 , and temperatures in °C of dry residual of washing liquid in g/dm 3 . The method enables to increase the performance of the registration and control of dry residue of the washing liquid, as well as to reduce inter-control intervals and thereby increase the intensity and effectiveness of the process control of washing wool. The solid residual of washing liquid is determined using a developed triaxial nomogram configured from the family of parallel linear dependencies of density of washing liquids on their temperature in the washing unit baths for the fixed values of solid residual of washing liquids and diagram of dependency of solid residual of washing liquid on the density of washing liquid at a temperature of 40°C. EFFECT: increased efficiency of washing wool, speed of technological process control of machine washing wool, reduction of the amount of detergents. 2 cl, 1 dwg


All children 3 years of age on Jan 1, 1975 in Fuchu City, Tokyo, a total of 17,044 of a population of 182,000, were examined neurologically at the Health Center and the Dept of Genetics, Tokyo Metropolitan Institute for Neurosciences, Tokyo, Japan.


Health care technologies in education mean to create the conditions, the package and the system of activities that provide health care educational sphere, conditions to preserve and strengthen pupils' health, to form value of health and healthy way of life, that is the essential, harmonic part of the organization of the process of education and upbringing students of the gymnasium # 13 of Traktorosavodsky district of Volgograd city. Except traditional forms of activities, which contribute to the preservation and strengthening health, other approaches are used in the gymnasium. They are based on the idea that conditions of upbringing and education of kids and teenagers, which correspond to modern conceptions of health care technologies, contribute greatly not only to the process of forming of their health but is one of the ways to increase effectiveness of education and its quality. The members of the foreign languages' department use to conduct monitorings of the effectiveness of using health care technologies in the process of education. Monitoring consists of three stages: 1. Dynamic analysis of lessons by the original form "Registration of the use of health care technologies" (RUHT), hat consists of 14 points of evaluation of hygienic organization of a lesson, from the point of view of the pupils' health protection. 2. Exposure of the correlated dependence of the level of using health care technologies and students' level of knowledge. The percentage wise of the integral data of the form "RUHT" and the quality of knowledge are compared, i.e. the number of marks "4" and "5" that pupils get at the lesson are taken into consideration. 3. Correction of the process of education as a result. The work is lead individually with the teachers to improve their pedagogical activity aimed to develop using health care technologies. The effectiveness of the work is tested be the following inspections of the lessons. Comparative analysis of the lessons in different grades and different teachers allows to making the following conclusions: 1. There exists direct correlative dependence between the level of hygienic rationalization of a lesson and the level of students' knowledge – the more points the lesson is given for hygienic rationalization, the higher quality of knowledge is; 2. As a result teachers begin to think about the necessity of taking into account operation facts of hygienic rationalization of lessons and followed them; 3. Taking into account operation facts of hygienic rationalization of lessons helps teachers to improve the process of teaching and increases level of students' knowledge. The work was submitted to VII international scientific conference «Modern providing educational process», Mexico (Acapulco), 2-14, March 2009, came to the editorial office 12.02.2009.


In search engine advertising (SEA), besides intense competition among advertisers (e.g., many retailers), there is channel coordination between retailers and manufacturers. This research attempts to investigate cooperative advertising in the SEA context, by considering a decision scenario including one retailer and one manufacturer, where the manufacturer carries out her own campaigns, and in the meanwhile, shares a fixed percentage (i.e., the participation rate) of the retailer's spending. Our model incorporates the dynamic quality score to study its effect on cooperative SEA strategies. Moreover, we provide a feedback Stackelberg solution for optimal cooperative strategies for the retailer and the manufacturer. Furthermore, we conduct computational experiments to evaluate our model and make sensitivity analysis with respect to the quality score and the participation rate. Experimental results generate normative findings providing critical insights for cooperative advertising participants in SEA.


The purpose of the paper is to describe a method for the simulation of recently introduced fluid stochastic Petri nets. Since such nets result in a rather complex set of partial differential equations, numerical solution becomes a formidable task. Because of a mixed, discrete and continuous state space, simulative solution also poses some interesting challenges, which are addressed in the paper.


The aim of this study is to evaluate the use of information and communication technology by faculty members at Al-Zaytoonah University in Jordan. Data were obtained from 42 faculty members from the faculties of information technology. A standardized questionnaire was used to obtain data from the research participants. Descriptive statistics, confidence interval, one-sample t-test, two-sample t-test, and one-way ANOVA were used to analyze the obtained data. This made it easier to assess the differences in usage by the different departments and faculties of the university. The result of the study was that there were no differences in the use of information and communication technology with regard to the educational status of the participants, ages, gender, and marital status. However, a difference was found in the academic degree and there were no differences in the number of hours and academic rank.


Background: Diabetes Mellitus (DM) is a disease that threatens global public
health with their chronic complication, such as Diabetic Foot Ulcer (DFU). There
are more macrophage phenotype M1 than M2 on DFU, that contribute to proinflamatory
cytokines secretion, and there is an alteration of EPCs in DM that
should have the ability of angiogenesis and neovascularization, so the wound
healing process in DM patient is slower than non-DM patient.
Objective: To prove in vitro role of Bone marrow (BM) derived EPCs in
polarization change of macrophage phenotype M1 and M2 in DM mice model
Methods: Peritoneal macrophages were co-cultured with EPCs and examined the
M1 and M2 markers by FACScalibur and qRT-PCR. The result would be
compared with the examination co-culture without EPCs.
Result: By FACScalibur examination, the results after co-culture with EPCs was
the M1 surface marker in control group were significantly decreased, namely
CD11c (p<0,0001), while M2 surface marker proved significantly increased, that
were CD206 (p<0,0001) and MGL1 (p<0,0001). The same results happened in
DM mice model group, that were CD11c (p<0,0001), CD206 (p=0,0445) and
MGL1 (p=0,0220). By qRT-PCR examination, the results after co-culture with
EPCs were the M1 genetic expression in DM mice model were significantly
decreased, namely CD11c (p<0,0001), TNF alpha (p=0,0002), IRF5 (p<0,0001),
while the M2 genetic expression proved significantly increased that were CD206
(p<0,0001), MGL1 (p=0,0002), Ym1 (p=0,0057), Arg1 (p=0,0234) and IL10
(p=0,0020).

Radiation effects and annealing characteristics have been investigated for different types of bipolar operational amplifier with JFET differential pair input at five dose rates ranging from 1 to 6.4×10-5 Gy (Si)/s for the same total doses. The results show that the effects vary with the type of devices in the given dose rates, one of which only has the time dependent effects (TDE), two of which not only have the TDE, but also the enhanced low dose rate sensitivity (ELDRS), and the last one shows that there is no difference when the IC was irradiated at different dose rates, but there exists the effect of "post-radiation damage" as annealing at room temperture. Possible mechanisms for these effects are discussed.


In December 2019 a novel coronavirus disease COVID-19 outbreak was first reported in Wuhan, China. Since then the disease has mushroomed in more than 210 countries/territories affecting 13,53,361 people and resulted in 79,235 total deaths and has emerged as a major public health issue. In India till April 8, 2020, 5194 cases of coronavirus disease (COVID-19) and 149 deaths from various states and union territories are reported. For a disease that was earlier thought as of zoonotic origin, person to person transmission of SARS-CoV-2 infection has led to the extensive spread of disease. COVID-19 has become pandemic due to its high potential to transmit infection from one person to another person, virus shedding before the development of overt symptoms and the evidence for superspreading events. To control any pandemic, we need to control infectious cases, reduce transmission and protect the susceptible population. Asymptomatic carriers can unknowingly transmit the disease to cohabiting family members. Social distancing can help in reducing the transmission of disease to susceptible individuals especially the elderly. The proportion of asymptomatic infections carriers varies from 1.2% to 37.5% among infected persons. Till the development of a safe and effective treatment or vaccine to control this pandemic, we need to diagnose all asymptomatic cases by comprehensive epidemiological investigation and aggressive testing of the at-risk population with RNA studies and antibody tests and isolate them from the healthy population.


We applied Iateral release in 57 patients having patellofemoral problems with different causes in the Istanbul University Istanbul Faculty of Medicine, Department of Orthopaedics and Traumatology, between December 1983-March 1995. The procedures were applied subcutaneously with open mini-insicion in 11 patients and intraaticularly with arthroscopy in 46 patients. Mean follow-up was 3.5 years. Patients were evaluated according to modified Lysholm scoring system and 65% excellent, very good and good result were obtained. In different Iiteratures, 7 -17% complication rates were given, so Iateral release is not an innocent procedure. Lateral release applied for anterior knee pain of very carefully choosen cases shows very dramatic improvement.
