Western medicine by law requires that drugs be synthetic compounds which are mass produced in heavily controlled manufacturing environments. In recent years there has been increasing interest in complementary and alternative medicine (CAM) for treating disease in the United States (e.g., White et al., 2017). Natural, nonvitamin, non-mineral dietary supplements account for a sizeable share of these approaches (17.7% in Clarke, Black, Stussman, Barnes, & Nahin, 2015). Despite their potential efficacy, a very small proportion of patients in the United States use CAM methods as complete replacements for standard pharmaceutical treatment (Nahin, Dahlhamer, & Stussman, 2010). Most CAM users reported taking natural dietary supplements for general wellness and preventative healthcare rather than specific outcomes (Marinac, Buchinger, Godfrey, Wooten, Sun, & Willsie, 2007). One reason is that identifying the dosages required for medicinal plant-derived compounds to treat specific diseases has proven difficult.


An electrostatic quadrupole device capable of deflecting an ion beam at right angles is described. It is useful for overlapping an ion beam and a laser beam. Its aberrations are negligible in many applications where fine focusing is not required. The construction is simpler and less expensive than other similar devices.


1* Introduction* Let Tlf T2, and U be bounded linear operators on a Hubert space where Tx and T2 are normal. The well-known theorem of Fuglede [13] asserts that if TtU = UT, then T?U= UT?. Putnam's generalization [13] states that if TiZ7= UT2 then T?U= UT2*. With this in view Berberian [3] defined an .FT-ring to be a ring with an involution x —> x* such that x*y = yx* whenever x is normal and xy — yx. Likewise a PΓ-ring is one which gives x?y — yxf for all x19 x2 normal and xγy = yx2. The usual examples of Banach *-algebras A [14] are FT and PΓ-algebras since they have faithful ^representations as bounded linear operators on a Hubert space. For our purposes we must demand somewhat more of A. We suppose that A is a semisimple hermitian *-algebra whose maximal commutative *-subalgebras are Shilov algebras and where xx* e W, W a minimal closed two-sided ideal implies that x e W. These requirements may seem special, but are actually satisfied by all J3*-algebras, all iϊ*-algebras and all group algebras of compact groups. Suppose that b Φ 0 in A and ba = ab — 0 for some a Φ 0 in A. We show that there exist c φ 0, h Φ 0, h self-adjoint, with be = cb = 0 and ch = he = 0 provided that either A has two closed two-sided ideals I Φ (0), J Φ (0) with I n J = (0) or A has zero socle. Without such hypotheses the conclusion can fail, as it does for the algebra of all 2x2 matrices over the complex field. 2* Notation and preliminaries* As is customary, a Banach *-algebras A is called hermitian if the spectrum of each self-adjoint element is real. Suppose that A is hermitian and semisimple. Then so is the algebra obtained by adjoining an identity to A. Therefore, the theory expounded in [12] for hermitian Banach *-algebras with an identity applies here to show that A has a faithful *-representation as bounded linear operators on a Hubert space. In particular, if x e A and xx* = 0 then x = 0. Ptak's development [12] involves a pene

A novel method has been established for the rapid separation and determination of 3 antioxidants(TBHQ,BHA and BHT) in foods.The target analytes were extracted with hexane-saturated acetonitrile and the extract was purified by gel permeation chromatography(GPC).The analytes were separated on a TR-35ms column(30 m × 0.25 mm,0.25 μm) and detected by tandem mass spectrometry with EI under multiple reaction-monitoring(MRM) mode.An excellent linearity(r 0.99) was observed in the concentration range of 0.05 to 10 mg/L for each antioxidant.The recovery rates ranged from 77.6% to 95.4% at three levels of 0.5,1.0 mg/L and 2.0 mg/L,with relative standard deviations(RSDs) of 2.7%-8.5%.The limits of detection were 0.03-0.1 mg/kg(n = 3) for these analytes.The established method is rapid,precise,sensitive,efficient and applicable for the analysis of TBHQ,BHA and BHT in foods.


Introduction • The Centers for Disease Control and Prevention Advisory Committee on Immunization Practices recommends vaccination against influenza for pregnant women.1 • Live attenuated influenza vaccine (LAIV) is not recommended to be administered during pregnancy; rare inadvertent administration of LAIV to pregnant women does occur. • There are limited data regarding fetal or maternal outcomes after LAIV administration during pregnancy. • Fetal outcomes among 6 individuals <18 years of age who were exposed to LAIV during pregnancy have been described. Among these pregnancies, there were 5 fullterm healthy infants and 1 preterm delivery.2 • A Vaccine Adverse Events Reporting System (VAERS) analysis described 2 women exposed to LAIV while pregnant; neither experienced any known adverse consequences.3 Objective • To analyze clinical trial and case report data regarding maternal and fetal outcomes for women exposed to LAIV during pregnancy Methods • All reports of women exposed to LAIV during pregnancy were collected and reviewed using data collected from clinical trials (September 1997 through April 2008) and spontaneous postlicensure reports (August 2003 through April 2008). • All available information on maternal and fetal outcomes was analyzed. • Adverse event data were obtained from pregnancy narratives.

In recent years, there has been a significant increase in the popularity of water-based tourism in Manado, particularly in the form of water sports and diving activities. Manado is known for its stunning marine biodiversity, including coral reefs, a variety of fish species, and other sea creatures. This has attracted a growing number of tourists, both domestic and international, seeking to explore the underwater world and enjoy the natural beauty of the area. This study aimed to explore the effect of tourists' motivation on their revisit intention to Batu Angus National Park, a popular tourist destination in Indonesia. Using a quantitative research approach, data was collected through a survey questionnaire distributed to tourists who had previously visited the park around 100 sample. The study findings indicated that the variable push motivation and pull motivation are significanlty influenced the variable revisit intention to the park. The study provides useful insights for park management and policymakers to enhance visitors' experience by catering to their motivational needs, which in turn can increase their revisit intention and boost tourism development in the region. Additionally, improving facilities such as adding more benches, rest areas, and public restrooms would provide greater convenience and comfort to visitors. These enhancements would not only attract more tourists to the park but also increase their revisit intention, which could potentially boost tourism development in the region.

Last year's we can observe an enormous grow of surveillance systems in the public domain. In many countries surveillance systems are under discussion because of the privacy aspects of people. In the nineties many multimodal systems were developed for surveillance in Dutch trains. The use of camera systems was complicated because of bad lighting conditions, occlusion and posture. Only recently it is possible to use smart cameras to localize and track faces and displayed facial expressions by smart cameras installed in the public domain. Most systems are based on the Active Appearance model. In this paper we present a real version of a surveillance systems called Image Processing System developed in the vision lab of TUDelft. In an experiment we recorded the behavior of stand-up comedians in trains acting in several scenarios. The facial expressions in the video footage were analyzed.


An array of four water Cerenkov detectors of variable depth (maximum 3.4 radiation lengths) has been used to study extensive air showers of size 105 to 106 particles. The amount of Cerenkov light produced is a measure of the total electron track length in the detectors resulting from the incident spectrum of electrons and photons. The difference between the lateral structure function as measured by the Cerenkov detectors and the known particle density distribution function is therefore related to the presence of cascading or attenuation in the water. This was confirmed by observations with Geiger counters above and below a detector. These effects in the water are thus a measure of the energy of the electron-photon component. The energy carried by this component per shower electron was found to vary between 440 ± 60 MeV at a distance of 2 m from the shower axis and 195 ± 35 MeV at 12 m distance. The part of this energy which is carried by photons was found to be greater than that carried by electrons throughout most of the region examined.


We examine whether rival CEOs' overconfidence influences a focal firm's research and development (R&D) expenditure. We propose a stylized model based on an R&D competition game with CEOs having a keeping-up-with-the-Joneses preference. Our model predicts that the overconfidence level of rival CEOs has a positive effect on the focal firm's R&D expenditure. We find supportive evidence to the model implications. The effect is stronger when (i) the product market is more competitive, (ii) it is less costly to finance R&D, and (iii) the new technology is more valuable. We also find that firms with more overconfident rivals have higher subsequent volatility in their stock returns and a greater risk of a price crash, but their innovation output and firm values are higher. Overall, we show that firms invest aggressively to not fall behind once their overconfident rivals' investments pay off, consistent with the concept of strategic complements in innovation.


Microscopic plastic particles have been found in the fats and lungs of two-thirds of the marine mammals in a graduate student's study of ocean microplastics. The presence of polymer particles and fibers in these animals suggests that microplastics can travel out of the digestive tract and lodge in the tissues. The study,


This investigative and practical work arose as a need for the Angel Polibio Chaves Educational Unit in the canton of Guaranda, in the province of Bolivar, because the activities that are carried out with respect to the control and monitoring of the students' academic reports are developed in a manual way, liberating the use of new information and communication technologies in these processes.

The start of the technological proposal went through several phases such as analysis, design, product development, pilot testing, evaluation and improvement, all these stages involved activities of vital importance to obtain a comprehensive product and provide a solution to the problematic detected.

In the end a computer system was developed to control the academic reports through the web as a result of the educational technology proposal raised as a general objective, so the actors of the educational community have the efficient, effective and accurate application to inform their representatives of the academic performance of their students.


We employed the multiple angle incident ellipsometer to study the growth mechanism and optical properties of semi-insulating polycrystalline silicon (SIPOS) films deposited by the low-pressure chemical vapor deposition (LPCVD) technique. A significant difference of the imaginary part of the refractive index between film at the edge and those in the central region of the wafer was observed. Our analyses showed that it was consistent with the N20 depletion model. This N20 depletion phenomenon was confirmed by Auger analysis. Moreover, we found that spatial N20 depletion at the edge of the wafer was greatly influenced by the flow rate of Sill4 to N20 gases. Excessively high N20 flow rate suppressed the silicon microcrystal formation, resulting in a thinner SIPOS film.


The information of influence of solar activities in the data series is pickedup by using stepbystep filtering and analyzed.It is revealed that the interdecadal variability of the monsoon climate over the East China Sea is very clear and represented in the following aspects.(1) The abrupt change.The atmospheric temperature at the sea level pressure layer and in the troposphere in July(summer) over the East China Sea has undergone a sharp change in the past half century which occurred in July 1978.Since July 1978,a period of persistent high temperature has began after a period of more than 30 a with comparatively low temperature.It lasted until the end of the 20th century.The temperature rising was more than(0.4 ℃).The data analysis indicates that the atmosphere temperature at all levels in the troposphere over the East China Sea in summer has this interdecadal variability.(2) Persistent increasing of the air temperature at the upper levels of the atmosphere.The atmosphere temperature at the middle part of the stratosphere(10 hPa) over the East China Sea in July(summer) is a persistent process of temperature rising with a wave form.The temperature has increased over 4 ℃ in the recent more than 50 years.The yearly ratio of the temperature rising is more than 0.075 ℃/a.The temperature at the bottom of the stratosphere(100 hPa) over the East China Sea also has the characteristic of the persistent rising of the temperature,which has shown a tendency of slowly rising since 1948 and has increased by 1.9 ℃ in the recent 53 a.The yearly ratio of the temperature rising is 0.036 ℃/a.(3) The periodicity.The air temperatures at different atmosphere levels over the East China Sea have the interdecadal variability with a 22 a period in various degrees.The amplitudes of the 22 a components rapidly decrease from upper to lower atmosphere levels.This indicates that the 22 a period is clear at the upper air,but not clear at the lower levels.There are also obvious decadal variations with an 11 a period at the middle part of the troposphere and the bottom of the stratosphere over the East China Sea.Based on the analysis,it is known that the 22 a period is caused by the period magnetic variation of the magnetic field of the sunspots.The 11 a period corresponds to the 11 a period of the relative number of the sunspots,and both are the reflection of the solar activity in the atmospheric climate.


In this paper, we consider the scenario of two collocated users communicating over Free-Space Optical (FSO) channels. We propose a novel cooperation scheme where the users jointly communicate symbols from an augmented constellation where each one of these symbols comprises two uncoded symbols each belonging to one of the users. We propose the structure of this 4-ary augmented constellation in the case where the users are initially employing binary Pulse Position Modulation (PPM). A performance analysis is then conducted over gamma-gamma channels reflecting the capability of the proposed scheme in doubling the diversity order for all levels of background radiation.


SUMMARY Complete septation of a double inlet left ventricle with left anterior subaortic outlet chamber was carried out successfully as a staged procedure during the first two years of life in a patient with severe pulmonary hypertension and an abnormal left atrioventricular valve. In contrast with isolated pulmonary artery banding, which rarely has led to a satisfactory septation or modified Fontan operation, this technique achieved good initial palliation and uncomplicated intracardiac repair. It should be considered for infants with univentricular atrioventricular connection, two atrioventricular valves, and excessive pulmonary blood flow. Although theoretically attractive,' septation of the univentricular heart during infancy has been hindered by technical difficulties in securing the pros-thetic patch and frequent postoperative heart block. Ebert recently demonstrated in five infants with "common ventricle" that two Teflon patches without a pressure difference across them could be positioned accurately with a few sutures, and that over a period of 5-8 months they became firmly adherent to the endocardium.2 This avoided injury to the conduction system and created a stable base to which a third patch was attached, completing the prosthetic septum. The following case illustrates successful extension of this concept to a patient with double inlet left ventricle and subaortic outlet chamber. Case report A baby girl weighing 5-5 kg was first seen at six months of age during emergency hospital admission for a chest infection. She was said to have been normal at full term delivery in Iran but had failed to thrive. A heart condition was diagnosed when she was three months old. On examination, the infant was pyrexial, tachy-pnoeic, and mildly cyanosed with clubbing. Bounding pulses at a rate of 160 beats per minute were present throughout. Enlargement of the heart with a thrill along the left stemal edge was detected by pal-pation. In addition to a loud systolic mumur, auscul-tation disclosed a single, accentuated, second heart Requests for reprints to sound. The liver was enlarged, and both lungs had diffuse crepitations. Chest x ray showed cardio-megaly with plethoric lung fields. The electro-cardiogram had a vertical axis and dominant left ventricular forces. Cross sectional echocardiography showed a large chamber of left ventricular morphology that received both atrioventricular valves and gave off the pulmonary artery. The aorta arose from a left-sided outlet chamber. The left atrium was dilated and the left atrioventricular valve appeared to be thickened. The patient's heart failure responded to treatment with digoxin and diuretics, …


Background: Urgent Care Centers (UCC) and Retail Clinics (RC) have become popular as the need for convenient care continues to grow in light of long waits to be seen by Emergency Departments (ED). Objective: To analyze the impact of UCC on the ED census of nearby hospitals. Methods: This retrospective analysis examined census for the EDs located within 2 miles from UCC. The census was obtained for a period of January 2010 through December 2015 from four different hospitals in New York City. This period corresponds to the rapid expansion of UCC in the metropolitan area. Results: Although some variation was seen during certain years, there was an increase in ED census in the year 2015 as compared to that of 2010. About 100 UCCs operate among the various boroughs of New York City that are capable of addressing illnesses that are classified by ED as ESI Level 4 and 5. Insurance companies would prefer patients to be seen by these centers rather than in costly EDs. Also the overall healthcare cost could potentially benefit if roughly 20% of the ED visits were seen in UCC. Nonetheless, no impact on total ED census was observed. Conclusion: While UCCs are relatively new in New York City and the wait time is much shorter for simple illnesses, the presence of UCCs did not decrease the census of main EDs. It is anticipated that these alternative care centers will play a bigger role in the future.


The leader of the Pietist revival in Germany was Philipp Jacob Spener (1635-1705). In 1670 this Lutheran pastor began to hold the collegia pietatis (or cottage prayer-meetings) out of which the nickname 'Pietismus' arose. The movement, which reacted against the cold formalism that had by then infected the Lutheran Church, aimed at a deepening of personal religion. Spener set forth his desiderata for his co-religionists in his Pia desideria, which appeared in 1675. One of the many lasting achievements of Pietism was the hymnody that it inspired. Erik Routley, the author of many perceptive publications on hymnology, was 'something of a hostile witness' as far as Pietism was concemed, since he had not fully understood the movement in its Lutheran setting. 2 In Lutheranism there had always been a strong strand of mystical devotion;8 but Routley did not distinguish between this orthodox Lutheran piety and the devotional aspects of Pietism as a specific historical movement. 4 At all events, by the late seventeenth century the main body of the Lutheran Church stood in need of revival. Not all Lutherans welcomed the new movement. One of its eloquent and vehement opponents in the pulpit and in the press was the High Lutheran court preacher Erdmann Neumeister (1671-1756). The underlying motive for his opposition was 'doubtless to preserve the simplicity of the faith from the subjective novelties of the period'. The author of one of the earliest historico-critical works on German poetry, he was also a pioneer composer of church cantatas. Many of his over 650 hymns were


Five-level classification of credit is the basic means of credit risk management advocated by Basel's Capital Agreement. However, there are some problems for the rural credit cooperatives of China to be aware of the exact classification in implementing the five-level system. Therefore, the paper analyzes these problems with sufficient examples and puts forward some countermeasures.


Some results on the study of algebraic methods for the analysis and design of time-frequency signal processing algorithms are presented. A time-frequency signal is defined as a signal whose spectral characteristics vary with time. Time-frequency signal processing is the mathematical treatment of signals with the objective of extracting relevant information. The processing of time-frequency signals is accomplished through the development of suitable algorithms. Emphasis placed on the analysis, design, and modification of time-frequency algorithms for machine implementation, and on the development of an environment to assist on this implementation. This environment is termed a computational mathematics environment (CME).<<ETX>>


A high-efficient coded cooperative scheme based on bit-interleaved coded modulation is proposed.Encoded bits of the cooperative user are partitioned into two frames,bit interleaved,mapped and then transmitted on the allocated time slots respectively.Bit interleaver is utilized to satisfy the fading coefficients of the different bits of a same symbol cound be modeled as i.i.d variables.One hand,the pairwire error probability over various fading channels is derived,and an upper-bound on bit-error probability is presented.Both theory analysis and simulations show that the BICM CC with high-order constellations can also achieve the full diversity under quai-static Rayleigh fading channels,whereas no any cooperation diversity over fast fading channels.On the other hand,labeling maps and interleavers are studied.It can be concluded that GRAY labeling is still optimum for the cooperative users and different interleavers of two frames can improve the performance.


In four-transistor (4T) CMOS image sensors (CIS), incomplete charge transfer from the photodiode (PD) to the floating diffusion (FD) node can result in image lag, which is a serious problem affecting the imaging performance. In the paper a low image lag 4T pixel structure for CIS is proposed. Two techniques are adopted to promote complete charge transfer in a 4T pixel. Firstly, the threshold voltage of the reset transistor in the 4T pixel is adjusted to an appropriate negative value to realize a high potential in the FD, which is helpful for the charge (electron) to transfer into FD. Inevitably, a large negative threshold voltage make the source-drain leakage current of the reset transistor can not be ignored. In the design the threshold voltage is chosen to satisfy the requirements of a higher potential in FD and a lower source-drain leakage current of reset transistor simultaneously. Secondly, an additional p-type layer is adopted on the surface of the photodiode, with partially overlapped the channel of the transfer transistor. With an optimized overlap length, neither an apparent potential barrier nor a severe potential pocket can be formed on the route of charge transfer. So a potential distribution under transfer gate conducive to charge transfer is achieved. An identical photomask is used to manufacture the additional p-type layer and the p-type pinned layer of the photodiode, and the latter is formed in selfaligned way, which is economic in process and helpful to control the misalignment of the layer. The simulations are completed in Technology Computer-Aided Design (TCAD) tools. A test chip with 32×10 pixel array has been designed and fabricated in 0.18μm 1P4M CIS process. The experimental results demonstrate that the image lag is below the measurement threshold (using 12-bit ADC) with an additional reset operation adopted. Without the additional reset, the largest measured image lag is 0.18%.


Most teachers of physics who teach mechanics at all levels of education make use of the traditional blocks to teach the laws of statics and dynamics. More complex movements like the ones of human body in jumps, kicks or throws are left out of this analysis. We propose a simplified way to analyze these movements through some basic concepts taught in traditional mechanics courses, especially the center of mass. In this approach, we begin with the study of particles, proceed to rigid bodies (which include the blocks) and then to the basic movements of the human body in some sports. Thus, we expect that the study of mechanics becomes more pleasurable and contextualized, as we have seen in lectures and courses. Given the breadth of the subject, we prefer to divide the article into topics. In this first article, we clarify the theoretical analysis and treat jumps in some collective sports.

Field tests of two jointless bridges are presented, focusing on the magnitude and significance of earth pressure behind the abutments. The Haavistonjoki Bridge is a 56-m-long, continuous three-span bridge. Instrumentation was used to measure the horizontal displacement of an abutment, abutment rotation, abutment pile strains, earth pressures behind the abutments, superstructure displacements, frost depth, and air temperature. The measured earth pressures were compared with pressures that had been calculated on the basis of Nordic codes of practice and the Eurocodes pertaining to bridges. The bridge over the Leduan is a single-span composite bridge with a cast-in-place concrete deck on top of two steel beams. This bridge, spanning 40 m, is slender, with a 1.7-m-high superstructure. The bridge was fitted with strain and displacement gauges and short-term measurements were made using a loaded truck. The field test results for this bridge were verified with calculations based on an abutment rotation stiffness calculation model developed during the research presented in this paper.


Kuntowijoyo is one of the prominent Indonesian Muslim philosophers who discusses Islamic epistemology. However, unlike most philosophers who focus on the process of Islamization of knowledge, Kuntowijoyo actually formulated the concept of scientific which is an epistemological idea of integrating between Islam and the sciences. The idea of integrating science and religion needs to be re-echoed in the third decade of the 21st century, given that this long-term program has not produced much in the treasures of Islamic scholarship, especially in Indonesia.This study aims to review the idea of integrating science and religion in the work of Islam as Science compiled by Kuntowijoyo. The type of this research is library research with analytical descriptive method. The object of research is the book Islam as a science, by Kuntowijoyo. The results of this study, that Kuntowijoyo offers a process of integrating science and religion in a concept he named scientific Islam, where science is derived from the texts of the Qur'an and As-Sunnah into the context of scientific reality. Kuntowijoyo hopes that, with this idea of scientific Islam, the sciences that are built can stand on the basis of the integration of science and religion, without dominating one of them, so that it can be applied to all humans in general. included in the development of national law because the concept of scientific Islam that initiates the integration between science and religion is also in line with the formation of national law that integrates religion and the state.


The optical constants n and k of amorphous and crystalline films of silicon have been found from measurements of reflectance and transmittance at normal incidence over the wavelength range from 2500 to 500 nm, and extended to 300 nm by the method of measuring reflectances from the specimen itself and after depositing on it a thin layer of Ta2O5. This latter method has also been made of the effects of annealing on amorphous films. The measurements on single-crystal silicon have been compared with the results of others obtained by Kramers-Kronig analysis.


Mothers with postpartum depression typically have several disabling symptoms which can be quite negative for themselves and their infants. Common symptoms related to depression include a loss of interest in activities, always feeling tired, not sleeping well, a change in appetite, and suicidal thoughts. Symptoms specifically related to motherhood include extreme worry about the infant's wellbeing, little interest in the infant, feelings of lost independence, fear of being alone with the infant, and interfering too much with the infant (American Psychiatric Association, 2000). Infants whose mothers had postpartum depression have been found to also have attachment disorders, impaired cognitive development, emotional developmental delays, and behavioural issues (Beck, 2001; Dennis, 2004).


We study the spreading of elastoviscoplastic (EVP) droplets under surface tension effects. The non- Newtonian material flows like a viscoelastic liquid above the yield stress and behaves like a viscoelastic solid below it. Hence, the droplet initially flows under surface tension forces but eventually reaches a final equilibrium shape when the stress everywhere inside the droplet falls below the resisting rheological stresses. We use numerical simulations and combine Volume-of-Fluid (VOF) method and an EVP constitutive model to systematically study the dynamics of spreading and the final shape of the droplets. The spreading process examined in this study finds applications in coating, droplet-based inkjet printing, and 3D printing, where complex fluids such as paints, thermoplastic filaments, or bio-inks are deposited onto surfaces. Additionally, the computational framework enables the study of a wide range of multiphase interfacial phenomena, from elastocapillarity to plastocapillarity.


Cloud computing promises to provide computing resources to a large number of service applications in an on demand manner. Traditionally, cloud providers such as Amazon only provide guaranteed allocation for compute and storage resources, and fail to support bandwidth requirements and performance isolation among these applications. To address this limitation, recently, a number of proposals advocate providing both guaranteed server and network resources in the form of Virtual Data Centers (VDCs). This raises the problem of optimally allocating both servers and data center networks to multiple VDCs in order to maximize the total revenue, while minimizing the total energy consumption in the data center. However, despite recent studies on this problem, none of the existing solutions have considered the possibility of using VM migration to dynamically adjust the resource allocation, in order to meet the fluctuating resource demand of VDCs. In this paper, we propose VDC Planner, a migration-aware dynamic virtual data center embedding framework that aims at achieving high revenue while minimizing the total energy cost over-time. Our framework supports various usage scenarios, including VDC embedding, VDC scaling as well as dynamic VDC consolidation. Through experiments using realistic workload traces, we show our proposed approach achieves both higher revenue and lower average scheduling delay compared to existing migration-oblivious solutions.


Symmetry-based channel digital twin is a great technology which can reproduce the communication channel of real scenes for performance evaluation of the wireless sensor network (WSN) inside tower buildings, based on the ray tracing (RT) method and machine learning (ML) theories, a cluster-based channel model is proposed in this paper. Meanwhile, an improved k-means method, which considers the weight of different dimensions in the multipath component distance (MCD) is presented for clustering, which has better clustering performance over the sparsity-based algorithm and traditional k-means algorithm. Moreover, the channel parameters such as cluster delay and cluster power are also investigated. On this basis, the communication performance of WSN, i.e., bit error rate (BER) and channel capacity are derived and analyzed. The simulation and analysis results show that the cluster model based on the RT method can get approximately equivalent channel impulse response (CIR), and the BER of proposed model is consistent with the simulated one. These results can provide reference for the node layout and optimization of WSN inside tower buildings.


An algorithm of ramp width reduction based on the gray information of neighborhood pixels is proposed, which can sharpen the ramp edge effectively Then, a new gray-weighted gradient operator and the automatic method to determine its parameter are introduced when detecting the transition region of images. Gray-weighted gradient operator can not only make the correlation of gradient and gray information as big as possible, but also resist the noise in the images. Some experiments show that the algorithm in this paper can extract the transition regaon more effectively.

Recent research documents that the widely accepted generalized likelihood uncertainty estimation (GLUE) method for describing forecasting precision and the impact of parameter uncertainty in rainfall/runoff watershed models fails to achieve the intended purpose when used with an informal likelihood measure. In particular, GLUE generally fails to produce intervals that capture the precision of estimated parameters, and the difference between predictions and future observations. This paper illustrates these problems with GLUE using a simple linear rainfall/runoff model so that model calibration is a linear regression problem for which exact expressions for prediction precision and parameter uncertainty are well known and understood. The simple regression example enables us to clearly and simply illustrate GLUE deficiencies. Beven and others have suggested that the choice of the likelihood measure used in a GLUE computation is subjective and may be selected to reflect the goals of the modeler. If an arbitrary likelihood is adopted that does not reasonably reflect the sampling distribution of the model errors, then GLUE generates arbitrary results without statistical validity that should not be used in scientific work. The traditional subjective likelihood measures that have been used with GLUE also fail to reflect the nonnormality, heteroscedasticity, and serial correlation among the residual errors generally found in real problems, and hence are poor metrics for even simple sensitivity analyses and model calibration. Most previous applications of GLUE only produce uncertainty intervals for the average model prediction, which by construction should not be expected to include future observations with the prescribed probability. We show how the GLUE methodology when properly implemented with a statistically valid likelihood function can provide prediction intervals for future observations which will agree with widely accepted and statistically valid analyses.


A simple dot-immunobinding assay (Dot-Iba) in nitrocellulose paper was developed for the detection of specific IgG antibody to Mycobacterium tuberculosis antigen 5 and mycobacterial antigen in cerebrospinal fluid of patients with tuberculous meningitis (TBM). The assay gave 77.1% sensitivity for the detection of IgG antibody to M. tuberculosis antigen 5 and 48.6% sensitivity for the detection of mycobacterial antigen in patients with TBM.


Historically, in Albania, as in other European countries, Roma people have had very low levels of education. Nomadic traditions and distinctive ways of living,poverty and discrimination are some of the main factors that explain this situation. In the 1930s of the last century, describing the Roma nomadism, Hasluck noted that they sometimes "settle in a city for a few months", but then turned back again to "tent life". In these circumstances, the education of children was something difficult. In the life of Roma, Gypsy and pilgrims - everything is about the family. It is the basic unit of social structure that makes up family groups; it is an economic entity in which work is done and a solidarity environment related to work is found; as well as an educational unit that ensures the fact that society reproduces itself and provides security and protection for the individual. In a world of change and unpredictable situations, the family is a feature of sustainability, synonymous with stability. The family is not simply the gathering of individuals within it; is a whole with its rights,an organ composed of members of the family, in solidarity to other families and foreign. Through qualitative method this study will identify the importance of the Romani family in the life of Roma children. The aim of the study is to observe how the relationship within family affects the educational life of Roma children and all relationship within the community.


The invention discloses a process and device for producing methyl sulfate with low dimethyl ether content. The process and the device are used for solving the problems in the prior art that the methyl ether content is high, special requirements of manufacturers cannot be met, and the like. The process is characterized in that during the distillation of a crude dimethyl sulfate product, dimethyl sulfate steam from a distillation still is subjected to two-stage cooling, first-stage dimethyl sulfate condensing temperature is controlled to 95 DEG C to 105 DEG C, and the degree of vacuum of a distillate collecting kettle is controlled to be lower than -0.08MPa; second-stage dimethyl sulfate cooling temperature is 30 DEG C to 40 DEG C, and the degree of vacuum of a distillate collecting kettle is controlled to be lower than -0.09MPa. The content of methyl ether in first-stage-collected high-temperature dimethyl sulfate is lower than 0.5%, and the yield of the first-stage-collected high-temperature dimethyl sulfate accounts for about 70% the total yield. A negative pressure system of the collecting kettle is connected with a dimethyl sulfate synthesizing tower, methyl ether, obtained through reduced-pressure high-temperature desorption, serves as a raw material for absorption again in the synthesizing tower and reacts with sulfur trioxide so as to synthesize dimethyl sulfate, and thus, the raw material consumption is lowered. The process and the device have the advantages of advanced process, simplicity in operation, raw material saving, high quality, low price, and the like, and the needs of some manufacturers with special requirements can be met.


Examination of gaseous blood composition using Van Sloik's method and oxihemometry by the patients with plutonium pneumosclerosis of different degree of heaviness showed that even by strongly pronounced pathologic process (the first and the second degrees) the gaseous blood composition during rest and, in particular, saturation of arterial and venous blood by oxygen is within the normal range.


REASONS FOR PERFORMING STUDY
No endoscopic examination of the nasolacrimal duct has been described before. In contrast with other imaging techniques, endoscopy provides a direct inspection of the intralumen and ductal mucosa in standing sedation.

OBJECTIVES
To provide a reference against which the endoscopic and clinical features of obstructive nasolacrimal disease in the horse may be compared.

METHODS
Endoscopic examination of the nasolacrimal duct was performed in 10 French Thoroughbred bay mares with a 3 mm shaft diameter flexible fibrescope. The duct was divided into 3 zones (1, 2 and 3) from the nostril to the lacrimal sac.

RESULTS
Endoscopic examination of the nasolacrimal duct appeared to be quite easy to perform in Zones 1 and 2, while the ease or difficulty of examining Zone 3 depended on the weight and size of the horse for the position of the endoscope in the lacrimal canal.

CONCLUSIONS
Endoscopic inspection has provided the possibility of a novel diagnostic approach to conditions of the nasolacrimal duct in horses.

POTENTIAL RELEVANCE
Endoscopic examination of the nasolacrimal duct could help to diagnose and treat nasolacrimal diseases by performing sample withdrawal and duct irrigation.

: An investigation on urban change detection was undertaken in Can Tho City, Vietnam, situated on the southern bank of the Hau River in the Mekong Delta. By using multi-temporal satellite images from 1972 to 2007, spatial urban expansion in Can Tho City and temporal trends in its urban development were elucidated to comprehend the city's evolution during different periods. The Vegetation-Soil-Water ( VSW ) index was applied for calculating the built-up areas, while the Normalized Difference Vegetation Index ( NDVI ) was adopted for enhancing accuracy of land cover classes. Land cover classification based on the Support Vector Machine ( SVM ) was found to provide better results than the Decision Tree ( DT ) method that was used by previous researchers such as Huang et al . ( 2002 ) , and Shafri and Ramle ( 2009 ) . The study revealed that the main direction of urban expansion in Can Tho City was north-westerly during the last 10 years followed by the rapid enlargement of the city along South-East and South-West directions. The results suggest that the more recently urbanized regions may become economically important, and therefore require quick improvements in social, economic and environmental planning. It was further observed that central districts have a population density 7 to 19 times higher than rural districts. Planned urbanization in the western direction needs to be encouraged in order to provide more opportunities for international trade and tourism in Kien Giang province due to its closer proximity with Thailand, Cambodia and Malaysia. On the other hand, the central areas of Can Tho City witnessing a high rate of urbanization may face risk of flooding and environmental degradation especially during the rainy season. Measures for better flood management in the outskirts of Can Tho City, using high resolution satellite images also need to be evaluated, with some urgency.


Cardiac computed tomography (CT) to detect coronary calcification was performed on 161 patients undergoing coronary angiography for proven or suspected coronary artery disease. Among 108 patients in whom coronary calci fications was identified, 90% had significant coronary stenosis angiographically (>75% stenosis), and 80% of 121 patients with significant coronary stenosis showed calcification by CT. The relationship between the calcification site and the significance in stenosis of each vessel was determined. Calcification was present in 133 arteries among 205 stenotic coronary arteries (sensitivity = 65%) as compared with 59 of 439 entire arteries with normal coronary angiograms (specificity = 87%). In the younger age group the sensitivity of calcification for stenosis of each coronary artery was lower and the specificity and predictive value were generally higher than those in the elderly group. These results demonstrate that CT is a valuable procedure for detecting coronary arterial disease, since this examination is easy to conduct, noninvasive, and widely applicable for screeening a large population.


This paper proposes Enhanced Fuzzy C-means technique (EFCM) based infrared image segmentation and its broad application in Automatic detection systems. The EFCM based image segmentation is able to approximate the exact number of clusters present in the image. EFCM based segmentation is applied on various infrared images that can be used for automatic detection systems and compared with widely used clustering techniques such as K-means and EM. Clustering performance has been compared in terms of well-proven and widely accepted validation indices, Global Silhouette Index and Separation Index. The segments or clusters obtained from above mentioned clustering methods have been assessed visually. Automatic Detection Systems based on EFCM can help in reducing complexities present in conventional systems.

Abstract Cell-bound phosphomonoesterase (PMEase) activity in relation to cellular P was compared in six strains of blue-green algae. In all strains, cell-bound PMEase was detectable at a relatively constant concentration of cellular P (X = 0.74% dry weight; n = 24, SD = 0.09), a value well above the minimum (c. 0.2% dry weight) of cellular P found in cultures whose filaments still appeared healthy and rich in enzyme activity. The switch-on time of PMEase came after 102–148 h of growth for Calothrix strains and Lyngbya and after 54–78 h for Nostoc strains. The peak of PMEase activity (6–8 μmol pNP mg dry wt−1 h−1) came after a marked decrease in cellular P, suggesting the presence of a strong relationship between PMEase and cellular P. This was confirmed when addition of P (10g P m−3) to the cultures increased the cellular P level and decreased the enzyme activity.


Petroleos Mexicanos reports excellent results with the use of stable foam as a circulating fluid during well-servicing operations. The technique is most effective in workovers involving low-pressure zones, the type often encountered in the southern part of Mexico. The stable foams are excellent circulating fluids because of their extremely low densities, Bingham plastic behavior, viscosities of 0-14 cP, and other characteristics desirable for low-pressure zones.

An important group of drugs that is always in demand in cases of emergency is the class known as the cardiac stimulants. It is true that they form rather an indefinite group and include drugs that have no direct effect on either heart or blood vessels, their only possible influence on the circulation being an indirect one. Perhaps those which are mentioned most commonly in this connection as being useful in cases of circulatory failure in acute infections are strychnin, camphor, epinephrin, digitalis, pituitary preparations and caffein. In this group should probably be included also the various solutions that are used for intravenous injections, such as Ringer's solution, and acacia and glucose solutions. It is true that some of the drugs named have been to a greater or less extent discredited for this purpose, and not so much reliance is placed on them now as there was some years ago.


In 2005, PS: Political Science and Politics published myriad articles covering a vast range of topics. Symposia alone published in 2005 focused on reviewing the 2004 presidential election, the careers of political scientists who graduated during "separate but equal," the politics of same-sex marriage, strategizing for department chairs in an era of resource constraints, the nature and political significance of preemption, a guide to publishing your first book, and the changing citizenship theory and practice. Upcoming symposia will focus on Middle East research methods, the editorial cartoon in politics, and the politics of water. And remember, these are only the symposia. The journal's commitment to publishing articles on pedagogy and on the profession, as well as exemplary topical scholarship on a wide array of topics, calls for an equally broad stable of expert reviewers. PS cannot publish such diverse work without the outstanding work (and open-mindedness) of our peer reviewers. The peer review process relies on the professionalism and generosity of those who contribute their time to read and evaluate the work of others. The editors of PS thank the following scholars, who served as manuscript reviewers between January 1, 2005, and December 31, 2005.


Byline: Todd Clark In 2004, the U.S. Secretary of Energy announced a new science education initiative to reinvigorate the U.S. Department of Energy's (DOE) involvement in K-12 science education (Abraham 2004). Part of this new initiative is a revitalized professional development program for educators, called the Laboratory Science Teacher Professional Development (LSTPD) program. This program has received new attention as part of President Bush's American Competitive Initiative, and the expected budget for 2007 will allow the DOE to triple the number of teachers and more than double the number of National Laboratories involved in the LSTPD program. The Office of Science at the DOE designed the LSTPD program with teacher input and by using current research and standards for the best practices of teacher professional development. The program's objective is to help teachers become ambassadors for the science community to students and their parents, agents for positive change in science education, and the inspiration for the next generation of scientists, engineers, technicians, and mathematicians that support scientific research for the DOE and the United States. Teachers, scientists, and program managers designed the LSTPD program to: Use the facilities and research communities of the DOE. Establish a long-term commitment between the DOE and the teachers involved in the program. For teachers to really believe they can use DOE resources in their teaching, they need to feel connected to the DOE scientific community and that will not happen in a short-term program. Be flexible. Teachers need options of differing summer program commitments-four to eight weeks-depending on, for example, their science backgrounds, family obligations, and what they expect to get from the program. Some DOE labs may be able to provide independent research experiences for high school teachers and other labs may be able to run workshops that focus on a particular research topic for middle school teachers. Address content knowledge that teachers will use in their classrooms. Allow teachers to work in a collaborative manner. Teachers should be able to share ideas about how to translate their lab experiences into ways that will impact student learning. Treat teachers as professionals. Teachers should be paid for work that they do to improve their teaching ability, and they should have opportunities to attend conferences and workshops that will help them stay current with the latest research in science and science education. Be scalable so that it can reach as many science teachers as possible. LSTPD teachers make a three-year commitment to the program. The seven labs participating include Argonne National Lab near Chicago; Brookhaven National Lab on Long Island, New York; Lawrence Berkeley National Lab in the San Francisco Bay area; the National Renewable Energy Lab near Denver, Colorado; Oak Ridge National Lab in eastern Tennessee; the Pacific Northwest National Lab in Washington State; and the Thomas Jefferson National Accelerator Facility near Norfolk, Virginia (Figure 1). With the anticipated additional funding in 2007, the LSTPD program will grow to include up to 17 DOE National Laboratories. Teachers may participate in programs at the same lab for all three summers, or they may participate in programs at three different labs. …


Abstract Wadi Qusayr 173 is an extramural, cache-like site that produced only a few dozen tabular scraper components. Interestingly, around half of these were placed in a group beside a natural lava rise. There was no evidence for associated structural remains, or even a pit or any kind of cover. This paper argues that the finds represent lost property originating with pastoral nomads making a round trip between flint quarries in the Jafr Basin and sedentary communities to the west. The discovery of property 'lost' in the process of transportation provides a glimpse into the realities of the system through which tabular scrapers were produced and distributed, and thus a key to exploring the social dynamics of the Levant in the Chalcolithic and the Early Bronze Ages.


With many advantageous features such as softness and better biocompatibility, flexible electronic device is a promising technology that can enable many emerging applications. However, most of the existing applications with flexible devices are sensors and drivers, while there is nearly no utilization aiming at complex computation, because the flexible devices have lower electron mobility, simple structure, and large process variation. In this paper, we propose an innovative method that enabled flexible devices to implement real-time and energy-efficient Difference-of-Gaussian, which illustrate feasibility and potentials for the flexible devices to achieve complicated real-time computation in future generation products.


Despite the recognized benefits of bus nubs in some locations, the safety and effectiveness of bus nubs are questioned in dense urban locations where heavy vehicular volumes and long bus dwell times may result in increased congestion if a bus nub is installed. In many urban areas with heavy bus and vehicular volumes, curbside parking is eliminated upstream of a bus stop to allow buses an easier access to the bus stop. Installing a bus nub at these locations would decrease roadway capacity resulting in increased delays to all vehicles on the road including buses. This paper describes the development of criteria for identifying locations where bus nubs would be appropriate for installation. The criteria are intended to ensure that the nubs will be effective in improving operations for buses, without significantly affecting roadway operations or causing safety concerns to pedestrians and bus patrons. The research attempts to quantify trade-offs between improved bus operations and possible increases in roadway congestion due to bus nubs.


The board leaderships play very crucial role when it comes to plan for the corporate goals and term objectives.

Dhanshree Pandey1,2 Aparna Chakrabarti1,2 1Homi Bhabha National Institute, Training School Complex, Anushakti Nagar, Mumbai 400094, India 2Theory and Simulations Laboratory, HRDS, Raja Ramanna Centre for Advanced Technology, Indore 452013, India. firstname.lastname@example.com, firstname.lastname@example.com Detection of toxic gases (like CO, NO, H2S, etc) has become an important issue for environment as well as human safety [1]. Carbon-based nanostructures including graphene as well as transition metal dichalcogenides (TMDs) [1] are widely studied in the literature to explore the possibility for the same. Recently, theoretical prediction on the possibility of tungsten monosulphide (WS) in the buckled configuration [2] has been reported by our group. This system shows a semi-metallic nature. Thus, in this work, we explore the possibility of CO and NO gas adsorption on WS using density functional theory (DFT) with van der Waals corrections based calculations. Adsorption energy (Eads) calculations and charge transfer analysis have been performed to estimate the sensitivity towards the gas molecule. We observe that CO and NO, molecules prefer the perpendicular adsorption on 2D sheet with C and N atoms oriented towards the sheet with appreciable values of Eads. Density of states study reveals that WS monolayer becomes semiconductor transition upon CO adsorption. Charge transfer theory shows that the bonding of CO and NO on WS surface occur through the 2π orbital (LUMO). Thus, the study indicates that WS monochalcogenide is sensitive towards the studied gas adsorbates and may be a potential candidate for CO and NO gas adsorption. The results await experimental validation.


. Formulation of the problem. In the school course of physics, the limits of applying linear laws are not discussed, which leads to their overuse in problem-solving. In this regard, it is necessary to 1) develop and describe a methodology for analyzing the limits of the application of linear models in the course of higher education physics; 2) cover examples of the application of some of the most important nonlinear models in the world to describe certain physical processes and phenomena. Materials and methods. Generalization and systematic analysis of literary primary sources on selected topics; the methods of mathematical analysis, system approach, problem-solving. Results. The effects associated with the nonlinearity of physical systems and processes are very diverse and manifest in both the macro and micro worlds. Linear models are usually a limiting case of nonlinear models and apply to fairly narrow intervals of argument change. Quantitative analysis of the limits of the application of linear physical models, which can be carried out with students during lectures or practical classes, should contribute to the formation and development of their ideas about the use of models of boundary transition in physics. The described method of analysis is deductive and allows us to consider from a single point of view several linear physical models. Conclusions. The excessive use and absolutization of linear physical models by students necessitates a systematic coverage of the limits of the application of "linear" laws in a university physics course and the introduction of the most significant non-linear models of phenomena and systems into the educational process. Preliminary learning results confirm the effectiveness of the described approach for the development of student model ideas.

Abstract : An amperometric titration method was developed for the determination of trace amounts of vanadium in steels and cast irons. This method does not require chemical separations, except in the case when more than 3% chromium is present, and may be used on the solution remaining from a routine chromium determination by visual titration. The method is applicable down to the 0.0002% level.


This study was investigated on biodiversity and life forms of plants distributed in 28 wetlands on Jeju city, in order to apply wetlands to nature exploration sites for environmental education. The 131 kinds of the plants were found on 28 wetlands. The plant biodiversity was relatively high in Ban pond, Jeongmool, Mosanimool, Dolgaegi pond, Woot pond, and etc. The life forms of plants, relatively high in variousness to other wet lands, were distributed in Mosanimool, Dolgaegi pond, Woot pond, and Yeonhoa pond as well as Jeongmool and Yongsoo reservoir. The 71 kinds, which correspond to 54.2% of plants observed in this study, were identified as hydrophytes. The forms of hydrophytes were distributed on 23 wetlands, including Jeongmool, Mosanimool, Yongsoo reservoir, Ban pond, Dolgaegi pond, and etc. In conclusion, 5 wetlands such as Jeongmool, Yongsoo reservoir, Dolgaegi pond, Mosanimool and Woot pond were high in variousness of plant life forms as well as biodiversity of plants. These results suggest that 5 wetlands above could be applied as nature exploration sites. In addition, Korean rare and endangered plants such as Isoetes japonica, Nymphoides coreana, Utricularia japonica and Sparganium stoloniferum in this study need to be conserved.


Polyaniline polymers were prepared using ethanol as solution in this paper while a kind of copolymer was formed with o-toluidine. And then the products were characterized and analyzed by the tests of infrared, electron microscopy and so on. The results shows that the products have the structure of nanorod, and the thermal stability of the copolymer proved to be worse than Polyaniline (PANI) after vulcanization process. Besides, the conductivity of the copolymer increased first and then decreased with the adding of o-toluidine, which is mainly due to the addition of polar groups methyl that affects π electron transfer speed on the molecular chain.


In this paper we investigate how the interaction between the product and the emission permit markets may affect firms' propensity to adopt cleaner technologies. The adoption of a cleaner technology has the direct effect of reducing the compliance cost of the firm, but it also involves a strategic decision, if the industry is not perfectly competitive. We look at this problem from both a theoretical and an experimental point of view. We develop a model of duopoly, in which two firms engage in quantity competition in the output market and behave as price takers in the permit market. Firms have the possibility of investing in a cleaner production technology, which is available on the market at some cost. We set up a dynamic game over an infinite horizon in order to investigate firms' investment decisions: in each period, each firm decides whether to invest in the new technology or not. The stationary equilibria to this game crucially depend on both the cost of switching to the cleanest technology and the emission cap. Technology diffusion is one of the possible equilibria of the game. In order to test the predictions of the theory, we design and implement an "innovation experiment" that replicates the "innovation game". The results of our pilot experiment suggest that firms' behaviour will eventually lead to innovation diffusion.

Administering the completion of bribery offences has gained importance, especially with regard to the statute of limitations. This study therefore deals on the one hand with the question of whether the existing jurisprudence in this regard is consistent with its own premises and how it has to be adopted by other legal institutions, which are relevant with regard to the concept of completion in this context (i.e. sentencing for multiple offences, the subject matter of the ruling, qualifications, examples of delimitation as well as principal and secondary participants). On the other hand it sheds light on whether the premises of the existing jurisprudence are correct at all.


ABSTRACT A viable citizenship program is pivotal for state development, and to let official policy determine politics as taught by T. J. Lowi. National states based on national-state citizenship are weaker and weaker before the key challenges of our times. That is why citizenship programs are more and more focused on innovation policies to integrate ius sanguinis, ius soli, citizenship on investment and citizenship on performance. This paper provides a strategic innovation policy by linking development and global citizenship. Innovative law-making, citizenship policy innovation, and development are dramatically interconnected to evolve a scenario in which citizenship represents a key intangible asset to generate tangible wealth in open horizons where free circulation of tangibles or intangibles is strategic and linked to downsizing the bureaucratic burdens, the local power centers by evolving a much leaner and higher organizational standard of citizenship: legally, isotropically, and socially. This results in a new theory of social systems as a useful tool for the management of the complexity of social relations, breaking territorial boundaries, and making them cosmopolitan (Beck, 2006. The cosmopolitan vision. Cambridge: Polity Press). In order to achieve this, the present study will be approached and related with cosmopolitism and development, aiming to bring new contours of study to this subject.


National Tuberculosis Institute is conducting a nationwide tuberculin survey among children aged 1-9 years in order to assess the current epidemiological situation of TB throughout the country. For the purpose of survey the country has been stratified into four geographical zones. In west zone Junagadh (Gujarath) Kota (Rajasthan) Jhabua (M.P) and Nagpur Thane and Rathnagiri (Maharashtra) have been selected for the survey. I was posted to Junagadh and Kota districts to supervise the survey work carried out there. I would like to share my field experience in these two districts in brief. (excerpt)


The semantic meaning of Obama's president election victory speech—Change Has Come To American is clear and the speech itself is a masterpiece. This paper tries to study the textual features of it and get a general knowledge of political speech. The thesis makes an analysis of the speech from the perspective of metafunction,finding out that the speech has its unique properties of text in terms of experiential function(transitivity),interpersonal function(mood,modality and personal pronoun)and textual function(thematic structure and cohesion).


It is a common theoretical view that (low) birth weight is a correlate of adverse birth outcomes but is not on the causal pathway to infant mortality. On the other hand the United States national policy for reducing infant mortality is to reduce low birth weight. If the theoretical view is correct lowering the low birth weight rate may have little effect on infant mortality. The development of covariate density defined mixtures of logistic regression a non-linear structural equation like model allows a formal test of the casual relationship between birth weight and infant mortality. This paper determines if maternal age influences birth outcomes directly and/or indirectly through birth weight in four populations. The results indicate that a) the majority of maternal age effects on infant mortality are direct and do not operate through birth weight b) maternal age does influence the birth weight distribution but c) the effect of maternal age on the birth weight distribution has little or no effect on infant mortality because the birth weight specific mortality curve shifts to compensate for changes in the birth weight distribution. This is consistent with the theoretical view that birth weight may not be causal. (authors)


Aluminum matrix composites have attractive attention for scientists and manufacturers. In this study, fullerene (C60) nanoparticle reinforced aluminum matrix composite was fabricated via semi powder metallurgy method. Microstructure analyzes were completed by X-ray diffraction (XRD) and Scanning Electron Microscope (SEM). Hardness, compression and tensile properties of unreinforced aluminum and C60 reinforced composite were evaluated. Results show that nanoparticle was homogenously distributed in matrix and there were no cracks or macro defects. Hardness was significantly improved with the addition of fullerene and extrusion process. Al-C60 composite exhibited better compression and tensile performance than pure aluminum.


By D. B. Simmons, M. I).—Within the last two years several cases which will admit of this classification have come into the hos pital for treatment. The hot iron, nitric, chromic, and carbolic acids were all tried in turn, as well as " Ricord's born enemy of phagedenic," with what we believe to be the average rate of success. The last four cases, and one especially, which we shall refer to, were almost entirely treated, however, by, if not a new pro cess, one which was productive of such satisfactory results as to warrant us earnestly recommending its trial. This consists in the continuous immersion of the deceased part in hot or warm water.


Indicators explaining gender differences in personality and pain among older cancer patients have not been adequately addressed. This study examined gender differences in cancer-related pain severity, the Five Factor Model of personality, and affect among older cancer patients (86 women, 64 men). No significant differences were found in pain severity between the gender groups. Analyses indicated that women scored significantly higher for the personality trait of neuroticism than men (p < .05). Further analyses showed that different demographic, health, and personality variables predicted pain severity in women and men. Gender was found to be a significant moderator in the association between the personality trait of neuroticism and average pain. These findings suggest that both gender and different personality types may influence reported pain severity. Specifically, the results suggest that how patients experience and report pain severity may be gender-specific, and that it may be inappropriate to assume that women and men experience, report, and manage their pain in similar ways. Future studies focusing on the influence of personality and gender on health outcomes are needed to assist healthcare providers in tailoring treatment, thereby promoting optimal symptom management.


Two articles contribute to an understanding of Conrad von Hotzendorf s personal life. Johann Christoph Allmeyer-Beck publishes and examines seven letters written by Conrad to the industrialist Louis Philippe Friedmann between 1915 and 1918. Kurt Peball analyzes Conrad's letters to his friend Walburga von Sonnleithner between 1905 and 1918. Finally, Richard Blaas examines the response of Metternich and the Austrian government to Giuseppe Mazzini and the founding of Young Italy and Young Europe in the early 1830's. He emphasizes the completeness of information supplied by secret agents and diplomatic sources and relates Metternich's efforts to have Mazzini expelled from Marseilles.


Industrial production index is an extremely important statistical indicator, which should reflect as faithfully as possible the actual variations of the industrial production volume evolution, both at the national level and in each self-governing territorial unit.Considering the high number of mainly theoretical approaches to the study of these methodologically complex issues, this paper aims at describing the theoretical aspects in a logically structured manner, while referring in a consistent manner to the main practical steps that need to be taken. The final goal is to disseminate statistical indicators that satisfy the information needs of all categories of beneficiaries. At the same time, one should also bear in mind that the statistical information about the short-term evolution of this industrial indicator must be provided in a consistent manner for all the European Union member states. In our paper, special emphasis is laid on ensuring an adequate sample representativeness level, both from the viewpoint of the number, structure and value of the industrial products composing it, seen through the eyes of families (CAEN Rev. 2 and PROD1), and from the viewpoint of the reporting businesses, mainly as concerns their turnover percentage in the self-governing territorial unit under consideration, in the year used as reference reporting year.


To increase the efficiency of any heat transfer processes which involves heat recovery from hot fluid or removal of excess heat via processing of cold fluid, the loss in available energy due to various irreversibilities must be analyzed in terms of entropy generation. In the present study, hot or cold fluid is passed through the inclined tubes with a square cross section, and the entropy generation characteristics within the entrapped fluid in triangular space during natural convection is the subject of investigation. The tubes are surrounded by cold fluid while hot fluid is passed through the tubes and vice versa. Thus, hot inclined walls with cold horizontal walls (case 1) and cold inclined walls with hot horizontal walls (case 2) are considered as boundary conditions during convection (Ra = 103 to 105) for various fluids (Pr = 0.015, 0.7, and 1000) within/surrounded by the tubes. Entropy generation maps (Sθ and Sψ) with heat transfer characteristics (ψ and θ) are analyzed for both the cases. Minimum sp...


Let $f$ be a chain mixing continuous onto mapping from the Cantor set onto itself.Let $g$ be an aperiodic homeomorphism on the Cantor set. We show that homeomorphisms that are topologically conjugate to g approximate $f$ in the topology of uniform convergence if a trivial necessary condition on periodic points is satisfied.In particular, let $f$ be a chain mixing continuous onto mapping from the Cantor set onto itself with a fixed point and g, an aperiodic homeomorphism on the Cantor set. Then, homeomorphisms that are topologically conjugate to $g$ approximate $f$.


The concept of fuzzy regression model with fuzzy regression coefficients was first introduced in [4], [5] and [6]. A fuzzy number can be uniquely determined through its position and entropy as described in [9]. Hence, by using the concept of fuzzy entropy the estimators of the fuzzy regression coefficients may be estimated. In the present communication, we develop a newer fuzzy linear regression (FLR) model with some restrictions in the form of prior information. We have obtained the estimators of regression coefficients with the help of fuzzy entropy for the restricted FLR model. Applications on some hypothetical numerical examples are provided in order to illustrate the proposed model and the obtained estimators. Cross validation of the regression model has been done based on computation of R2 and using F-test. The proposed model may find applications in various areas of actuarial sciences, fuzzy time series analysis, management decision making etc.


Abstract
In this chapter, the author critically examines the relationship between sociology and the identities/experiences of disability and 'mental illness' (referred to throughout as distress). The author argues that despite sociology having an ethos of social justice and frequently producing critical accounts of inequalities – such as anti-racism and gender equality – it nonetheless uncritically reiterates the marginalisation of disability and distress. As such, sociology not only reflects the increasing 'medicalisation of everyday life' and shores up the essentialist discourses of genetics and neuroscience, but also consigns research and knowledge production about disability and distress to the medical sciences. The author challenges these sociological conventions and highlights the ways in which both disability and distress are socially structured, embodied experiences. The author argues that a sociological account of distress and disability are important not only in and of themselves, but also because they highlight the ways and means to challenge essentialism, inequality and the ever-narrowing definition of what is considered a normal or acceptable part of human experience. Furthermore, vibrant streams of user-led research, activism and practice-interventions – resulting in widespread social, legal and identity transformations – have emerged from the experiences of disability and distress. These user-led perspectives highlight the importance and potential of knowledge produced from the margins, not only for those experiencing disability and/or distress but also for the ways in which we perceive, theorise and research the social world more broadly.


A moving horizon estimation (MHE) technique was used to estimate thin film growth rate, thickness, and high temperature optical constants in situ from a normal reflectance measurement. The advantage of MHE over the virtual interface (VI) method is that it does not require the assumption of constant film growth rate and optical properties, and this allows in situ monitoring of more general dynamic film growth processes. MHE and VI methods were applied to a simulated film growth process in which film growth rate and extinction coefficient are changing with time. The result indicated that MHE gave a better estimate by capturing the change of film growth rate and extinction coefficient, while VI method only gave an averaged growth rate and extinction coefficient. The MHE and VI methods were also compared in an experimental CVD testbed where a polycrystalline yttria thin film was deposited on a silicon substrate by MOCVD. Although these two methods gave roughly the same estimate of film properties at the end point, MHE additionally estimated the dynamic change of film properties during the deposition. Finally the connection between the MHE and VI method was discussed and it was shown that a finite horizon implementation of VI is a special case of MHE when certain weighting matrices are discarded.


A technique enabling systematic observations of metallurgical features in the electron microscope is outlined. Such features of interest are suitably marked; and wet stripped plastic replicas are prepared in the normal manner. A simple apparatus, briefly described, allows one to position these replicas on electron microscope specimen grids as desired. This permits direct comparison of electron and photo micrographs of any surface detail. In addition, changes in surface detail or of a given feature in depth may be followed.


In this study, perceptual mapping was used to identify the collective and individual positions of 10 competing southern states. The perceived position of the ideal state also was captured by the study's findings. Industrial real estate executives who were surveyed indicated that some states have positioned themselves strategically in terms of quality of life, whereas others are recognized because of their resources or business environment. Some states appear better able to take advantage of their position, whereas others face development obstacles.


The dendrite model, which was derived based on phase field simulation result, was chosen to obtain a series of images of the dendrite's cross-section along the height direction. The images were then black–white–binary processed and reconstructed to reveal the 3D morphology of the dendrite. The relationship of permeability with height, temperature, and solid fraction was calculated based on Blake–Kozeny model, which is helpful for the comparison of classical theories and experiment results later. The mushy zone which contains the dendrite and liquid was chosen to research, the meshes for calculation were generated based on the 3D morphology of the dendrite. The flow field as well as the solute distribution in the mushy zone under ultrasonic treatment was calculated using ANSYS Fluent, it is found that the tortuosity of the streamlines in liquid is apparently larger than that in the dendrite, the promotion of solute diffusion caused by ultrasonic treatment in liquid is much more effective than that in the dendrite. The fluid flow could significantly boost the solute diffusion to the melt, fluid flow is a key factor which determines the solute distribution in the mushy zone during solidification.


A case of mucinous cystadenoma of the appendix accidentally found at an operation for a gastric cancer is reported. A 71-year-old man underwent a distal gastrectomy for an early gastric cancer. During abdominal exploration, mucous like geratinoid substance attached to the serosa of the appendix was identified, and a 1×1cm concomitant tumor was palpable at the root of the appendix. It was diagnosed as rupture of the appendiceal mucocele, and ileocecal resection was added. Histological examination showed that the lumen of the appendix was filled by mucous semisolid material, and that the cavity was lined by mucinsereting epithelium arranged in a papillary pattern. Microscopic diagnosis was reptured mucinous cystadenoma of the appendix. Twelve cases of mucinous cystadenoma of the appendix have been reported in Japan, including this case. The most common complaint was right lower abdominal mass (5 cases), followed abdominal pain (3 cases). Three out of the 12 cases were asymptomatic and accidentally detected like this case. The importance of the whole exploration at the abdomonal operation should be emphasized.


In acute liver failure (alf) there is a defect in synthesis of coagulation factors in addition there is a disseminated intravascular coagulation which is followed by an impairment of the microcirculation. With an early substitution of Antithrombin III (AT III) we tried to stop this situation. In 22 patients (10 female, 12 male, age 10-68) with alf presenting with hepatic coma (grade I-IV) we studied the time course of AT III plasma activity (the study started in December 1978 and is continued until now). AT III was measured with the chromogenic substrate method. When AT III activity fell below the level of 80% of normal, we started to substitute AT III and to give low dose heparin (125-500 U/hrs). In addition in case of bleeding or a decrease of coagulation factors or fibrinogen under the hemostatic active concentration, complexes of prothrombin and fibrinogen were administered. Besides the usual conservative treatment for alf, patients in coma (grade IV) were undergoing baboon liver perfusion. The rapid fall of the hepatic coagulation factors stopped. In patients, who still were able to synthesize coagulation factors a reincrease of these factors after administration of AT III was seen and there was a further fall in fibrinogen. The dosage of AT III in alf required to bring AT III to normal values depended on the degree of intravascular coagulation. The average dose in our study was 250 U/3 hrs. The clinical course of alf was prolonged in all patients and 7 patients with the prognostic deleterious colombindex (sum of factors II + V + VIII) < 75% eventually survived the alf. The coagulation disorders in alf can be treated with an early substitution of AT III; thus, there is more time for liver regeneration. Our results suggest an improved prognosis of the acute liver failure.


Purpose
This paper aims to provide an analysis of securities class action filings in 2017 along with related trends over time and a comprehensive current view of the securities class action landscape.

Design/methodology/approach
The paper details 2017 securities class actions and related trends by measures including the number and size of filings; market capitalization losses; litigation likelihood for US versus non-US exchange-listed companies; status and outcomes of filings (settled, dismissed, continuing); core versus merger and acquisition filings; individual versus institutional investors as lead plaintiffs; and concentration of class action activity by industry sector, stock exchange and court circuit.

The salvage process of surface defect of iron casting belongs to a welding-on process for repairing surface defect of iron casting and includes the following steps: cleaning surface defect; rapid-preheating the surface defect; jetting nickel-based alloy powder to form covering layer; rapid-heating the covering layer to make it into molten state; rapid jetting nickel-based alloy powder to fill defect to the required size; then cooling to room temp. so as to implement the welding-on process. Said invented process changes the traditional slow-heating and cooling welding-on theory and technological process, and can make the base metal tissue of the repaired metal casting basically retain its original tissue and property so as to can fully ensure its finishing and working properties.


As the new energy technology gradually matures, people are more and more enthusiastic about the use of new energy. The formerly tall new energy has gradually become common consumers, such as new energy vehicles, solar water heaters, roof photovoltaic power supply, etc.In fact, our elevators have unique conditions to use new energy, but elevator new energy technology is still rarely used. On the one hand, ordinary consumers pay little attention to elevators, and on the other hand, manufacturers' technological innovation often only focuses on cost reduction and profit maximization, or only to meet national mandatory standards.


Chiral-phase HPLC has been widely used as an essential means of separating and quantifying enantiomers in biological and synthetic samples. The methodology has been extended to the direct resolution of various synthetic and naturally occurring chiral glycerolipids, such as triacylglycerols and phospholipids, since the enantiomer resolution of synthetic monoand diacylglycerols as 3,5-dinitrophenylurethane derivatives was achieved by chiral-phase HPLC in the 1980s. This review describes recent advances and applications of chiral-phase HPLC in lipid research. In particular it is focused on the analysis of enantiomeric glycerolipids including triacylglycerols and phospholipids.


It has been widely reported that pre‐injury use of anticoagulant and antiplatelet agents can affect traumatic brain injury and the associated risk of mortality, however, the effect of these agents on non‐head injury site‐related blood loss remains unclear. Therefore, we investigated the effects of pre‐injury anticoagulant and antiplatelet agents on the transfusion amount and the need for massive transfusion in elderly patients with severe trauma.


21st century, a new period, is characterized by knowledge economy. With the opportunity and challenge of knowledge economy, medical education has to make its correspondent changes, that is, from biological medical science to the combination of biological, mental and social medical science, from examination-oriented education to quality-oriented education. How to effectively train medical talents is an urgent question for doctors to fall into deep and careful consideration.
