The origin of the isotopically anomalous oxygen components found in various meteorites is generally attributed to galactic nucleosyn thesis processes (Clayton et al., 1973, .1976, 1978). The oxygen anomalies can be explained alternatively as due to an intense irradiation of the solar system materials during the T-Tauri phase of the young Sun (Kuroda, 1975, 1982), which produced isotopic anomalies in a wide variety of substances including the light ele ments carbon and nitrogen (Kuroda, 1985), as well as the rare gas element xenon (Saebo and Kuroda, 1985). The purpose of this note is to point out the possibility that the existing data on oxygen anomalies may provide us with in formation concerning the locations where the high temperature mineral inclusions of the meteorites have originated. Recent observational and theoretical evi dences support the idea that the young Sun passed through a high-activity or T-Tauri phase (Worden et al., 1981; Feigelson, 1982; Strazzulla, 1985). It is not a simple matter, however, to secure the exact value of high energy proton fluence (Fr) received by the solar system material during the intense irradia tion period. According to Worden et al. (1981), the flux of high energy protons (E > 10MeV) may have been as large as 2 X 108cm-2s-1 at 1 AU. Feigelson (1982) has reported a proton flux of about 4 X 106 cm-2 s-1 at 1 AU for the young Sun. If it is assumed that the T-Tauri phase lasted for a period of 107 years (Fowler et al., 1962), the total high energy proton fluence (Fp) received by the solar system mate rial at 1 AU is calculated to be as high as

The second edition of Dr Swischuk's book provides a much-needed comprehensive overview of neonatal and infant radiology. The text has been revised and updated, and has been greatly expanded to include reviews of recent developments and concepts in the study of gastrointestinal, genitourinary, and neurological problems encountered in the neonate and young infant. Noteworthy areas of coverage that would be of interest to pediatricians and radiologists include topics such as the use of ultrasound in the detection of intracranial hemorrhage, urinary tract abnormalities, and infection, gastroesophageal reflux, and neonatal sepsis. Discussions about techniques of examination of these small patients including integration and illustration of the roles and uses of ultrasound and computed tomography, as well as pitfalls of interpretation and normal variants, make this a useful book for reference to over and over again. Numerous illustrations and diagrams accompany the text, and are clearly labeled and of good quality for


The study analyzed the adaptation to climate change among rubber farmers in Delta state, Nigeria. A multistage random sampling technique was used to select 50 rubber farmers. Data were analyzed using descriptive and inferential statistics. Results revealed that 40% of the respondents were 56 years of age and above. Majority were male and married and 46% had secondary school education. The result of the adaptation measures employed includes fire tracing (85%), mulching/cover cropping (80%) and off-farm activities (72.5%). Analysis of the relationships between some selected socio-economic variables and the use of climate change adaptation measures revealed that age, years spent in school, household size, extension visit and distance of farmers' residence to farm land had significant relationship with coping strategies employed. The main constraints to the use of climate change adaptation measures by farmers in the study area were poor financial resources (95%) and poor access to weather information (90%). The study concluded that there should be awareness creation of climate change and possible adaptation method to be used by rubber farmers. Also, extension service should be strengthened through organizing adult education programmes for rubber farmers to expose them to climate change coping strategies.


Waveguide switchable bandstop and bandpass filter designs are demonstrated in this paper. The designs are based on the design of rectangular waveguide that has switching planar bandstop resonators inserted on the sidewall. These switchable bandstop resonators consist of two identical metal patches separated by switching elements. The switching elements can be of RF MEMS or semiconductor transistor type. These resonators allow electrically switching of the waveguide while providing close to ideal on-state insertion loss and narrow stop band during off-state. These switches permit the switchable bandstop and bandpass filters design. The concept is demonstrated for a switchable five-pole bandstop filter and a switchable three-pole bandpass filter, both at the centre frequency of 14.25 GHz and for 500 MHz bandwidth.


Scholars have shown that individuals use candidate traits in different ways when evaluating those running for office. Much of this research deals with how sophistication conditions the use of traits, but less is known about how real world situations shape when an individual's use of certain traits in formulating opinions is activated. This paper inquires into how perceptions of real world conditions affect the desirability of certain traits (and as such, certain candidates) in a campaign setting. More specifically, the paper assesses (through an original survey experiment presenting subjects with differing political biographies) how individuals' sociotropic and pocketbook assessments of the economy drive their reactions to candidates with varying levels of experience in the fields of economics and business. The paper argues and tests the idea that individuals who perceive problems with their own economic situations and the national economy will evaluate candidates with economic-oriented educational backgrounds and experience running businesses more highly than candidates lacking these traits.


Along with the rapid development of cloud computing, researchers are getting more and more interested in this area. Since there is abundant of cloud data in cloud and a large number of users, cloud storage technology is becoming a key technology in cloud computing. The mainstream cloud platform and cloud storage technology are introduced in detail in this study. And the challenges under new situation and requirements are also discussed.


Objective: In Alzheimer's FDG PET research, the choice of reference region for normalization and use of partial volume correction are inconsistent and have not been studied in a large multi-center study. Herein, we identified which normalization region provided the highest degree of discrimination between subjects who were classified as normal aging, mild cognitive impairment, or Alzheimer's disease. The effects of partial volume correction using either a gray matter mask or cortical thickness and subcortical volume residuals were also examined. Methods: Stepwise logistic regression models were used to identify the optimal normalization region and partial volume correction method to discriminate between disease stages in over 400 subjects from research sites across North America. Normalization region candidates were the brainstem, precentral gyrus, postcentral gyrus, cerebellum, and thalamus. Partial volume correction methods tested were anatomically or statistically based. Results: Pre- and post- central gyri, and the thalamus showed AD-related changes in FDG PET and did not qualify for further testing. Normalizing to the cerebellum while using the gray matter mask for partial volume correction provided the highest indicator of discrimination. Conclusions: Normalization region and partial volume correction are critical to FDG PET analysis and candidate normalization regions should be tested for disease effects in the study sample prior to use. Cerebellar normalization and gray matter mask partial volume correction are recommended for use with the ADNI dataset.


This study examined linear viscoelasticity (LVE) of stereo-regular poly(1-butene) (PB) and its random copolymer with polyethylene, with number fraction of ethylene comonomer ≤10%, using a conventional shear rheometer combined with a quartz resonator. This combination resulted in the detection of LVE in a broad frequency range from Rouse region to terminal relaxation. LVE, thus, determined was fit to the double reptation model through utilizing inputting molecular weights determined by gel permeation chromatography equipped with refractive index and two-angle laser light scattering monitors, and the segmental time and entanglement molecular weight as the two fitting parameters. A quantitative prediction was finally achieved when the two fitting parameters changed systematically by the increase of ethylene content, a decrease of segmental time quantified a plasticizing effect, and a decrease of entanglement molecular weight reflected enhanced the chain flexibility. The entanglement molecular weight of the PB samples was found to be lower than those reported for stereo-irregular PB, suggesting the important effect of stereo-regularity on the chain flexibility.This study examined linear viscoelasticity (LVE) of stereo-regular poly(1-butene) (PB) and its random copolymer with polyethylene, with number fraction of ethylene comonomer ≤10%, using a conventional shear rheometer combined with a quartz resonator.

Si3N4 photonic integrated circuits have gain significant and rapid interest in different photonic applications thanks to its superior passive performance. Nevertheless, optical integration between Si3N4 and Ge-based optical components remains critically challenging especially for optical modulation. In this paper, via 3D-FDTD calculations we investigate the optical integration between Si3N4 and Ge-based waveguides using vertical coupling configuration employing amorphous Si ( $\alpha $ -Si) as an optical bridge showing efficient and robust coupling efficiency, which can be maintained according to the tolerant analysis with respect to the variations in optical wavelengths and critical parameters of the coupling structure. In addition, with respect to the recent theoretically-optimized SOI waveguide-integrated and also laterally-coupled Si3N4 waveguide-integrated Ge-based optical modulators, we found that the studied coupling structure could be employed to enable a low-voltage Si3N4 waveguide-integrated Ge-based optical modulator with a competitive extinction ratio/insertion loss performance, increasing the prospect of Si3N4-based photonic integrated circuits for low-energy optical interconnects.


Taking into account prior research suggesting a lack of student participation in online discussions, this study examines the influence of peer moderator (PM) role assignment on students' participation and that of their peers' participation in online discussions. Eighty-four participants operated in a moderator role, reciprocally. Moreover, the study examines the differences in the level of e-moderation supports enacted by PMs of high-and low-density online discussions. Online participation was assessed using log files of seven-week discussions and social network analysis techniques. Quantitative content analysis was applied with online interaction transcripts of PMs for two groups of online discussions. The results indicated that students in the PM role reached significantly higher level of participation quantity and patterns and their non-posting participation significantly influenced all indicators of group participation. Further, high-and low-density online discussions differed significantly with regards to frequency of PMs' e-moderation supports.


Policies that restrict the spaces in which alcohol can be consumed are now widely implemented around the world. Bans on the public consumption of alcohol are particularly common in Western countries, including North America, the United Kingdom, Nordic countries, Australia and New Zealand. In Australia, partial or complete bans on drinking in public operate to some degree in all major cities, as well as in many regional and rural towns (Webb 2004).


A breast tumour resembling the tall cell variant of a papillary thyroid carcinoma (BTPTC) was first reported in 2003 by Eusebi and colleagues.1 It was described as a breast carcinoma with histological features similar to the tall cell variant of a papillary thyroid carcinoma. These breast tumours are generally considered of indolent behaviour. There are however not enough data to predict prognosis in these rare variants of breast cancer. Since the original description of BTPTC in 2003, only a handful of additional reports of the same type of lesion have been described.2–5 These cases can be challenging, and the first differential diagnosis to take into consideration is a metastatic papillary thyroid carcinoma.

Here, we report a case of a BTPTC in a 55-year-old patient with Lynch syndrome (LS) who presented with asymmetric density within her right medial upper breast on a routine mammogram. Spot …


Efficient logistics management requires knowledge's possession and practical use of it. It is also necessary to manage knowledge in an effective way. Its goal and accomplished tasks can be considered in the context of logistics management. It can be said that logistics management can in fact be treated as logistics knowledge management. It includes not only the final use of knowledge as a factor enabling to obtain their goals, but also the realization of all processes associated with the movement of that knowledge. Knowledge is therefore also the subject of logistics management and optimization determinant of its effectiveness.


We explore the possibility of using ternary Si1?x?yGexCy grown on Si as the material for detection of infrared light of wavelengths 1.3 µm and 1.55 µm. By using an empirical expression for the absorption coefficient , it is ensured that the ternary alloy exhibits values of as high as 5000 cm?1 at these wavelengths. From the corresponding values of the band gap, the compositions of the alloy are then ascertained by using an existing theory of band gap and band offset of ternary SiGeC alloy grown on (001) oriented Si. The estimated compositions are displayed as plots of x versus y (0.03) with different values of as parameters.


MPI middleware glues together the components necessary for execution. Almost all implementations have a communication component also called a message progression layer that progresses outstanding messages and maintains their state. The goal of this work is to thin or eliminate this communication component by pushing the functionality down onto the standard IP stack in order to take advantage of potential advances in commodity networking. We introduce a TCP-based design that successfully eliminates the communication component. We discuss how this eliminated TCP-based design doesn't scale and show a more scalable design based on the stream control transmission protocol (SCTP) that has a thinned communication component. We compare the designs showing why SCTP one-to-many sockets in their current form can only thin the communication component. We show what additional features would be required of SCTP to enable a practical design with a fully eliminated communication component


The registration information system at the BLK Surakarta enables data redundancy. It will be analyzed to avoid this. The process of registering student services into the system is limited to the number of prospective students but input data is still unable to implement policies so that when data input still occurs or data from the same data or many data often occur.           This study uses Cobit 4.1 to audit the registration information system available at the BLK Surakarta. The selected subdomain is the Delivery Subdomain and Support DS 10 and DS11, the purpose of which is to determine the maturity level value in the IT process that has been applied in the BLK Surakarta and provide recommendations that need to be corrected. Based on the maturity level statement in the Maturity Management Guidelines Control Framework.  The resulting output is the study indicate that BLK Surakarta must conduct system performance evaluations that are routinely carried out with those responsible for identifying and tracking problems so that they are aware of the current system conditions. In Domain 10 of Delivery & Support, the results of the Current Maturity Level calculation are 3.27 with conditions Determining the Process. While Domain Deliver & Support 11, the result of calculation of Current Maturity Level is 3.31 with the Requirements for Determining the Process. The new student registration section has implemented a payment data management process but the lack of available tools makes data management less than optimal.Keywords: Student Registration Services, Registration Information System, COBIT 4.1, DS 10  and DS11 Domains, Defined Process


Creating space is the essence of architectural design. Architects actually work with three-dimensional (3-D) space, although twodimensional (2-D) drawings are perhaps the most commonly used design medium. It is thus valuable to help architects truly see 3-D space, while making drawings in 2-D. In addition, architects usually use symbols in their drawings to identify architectural concepts. By recognizing the symbols, it is possible to identify architectural configurations of the design. This paper introduces a symbol-based modeling tool—SpaceMaker—that allows architects to make freehand floor plans and apply symbols to identify different functional spaces. SpaceMaker then converts those floor plans into 3-D models according to the symbols.


The cumulative impacts of frequent moderate-magnitude eruptions on stratospheric aerosols were identified among the factors in recent decadal climate trends. Moderate volcanic eruptions are a recurrent source of sulfur dioxide (SO2) in the Upper Troposphere and Lower Stratosphere (UTLS) region and the resulting formation of sulfuric acid aerosol particles from the SO2 emitted provides sites for chemical reactions leading to enhancement of stratospheric optical depth (SAOD) and ozone depletion. Modelling properly the volcanic aerosol content and its evolution in this region is important for radiative impact issues. In this work, we explore the variability of the tropical UTLS aerosol content between 2013 and 2019, a period which was particularly impacted by moderate tropical and mid-latitude volcanic eruptions. For that purpose, space-borne observations from OMPS (version 2, datasets from GES DISC), and IASI, together with simulations by the Whole Atmosphere Community Climate Model (WACCM) coupled with the Community Aerosol and Radiation Model for Atmospheres (CARMA), are used. Different model sensitive experiments, particularly for the injection altitude and timing, have been conducted to evaluate how the model captures the aerosol plume in terms of content, optical and microphysical properties, transport and residence time. We find that the decay of the Calbuco and Kelud plumes observed by OMPS version 2 is well reproduced by the model. Comparisons with unique datasets in the tropical southern hemisphere from the NDACC Maïdo observatory (Reunion Island, France, 20.5°S, 55.5°E) show good agreement between the lidar SAOD observations and WACCM-CARMA SAOD simulations although we observe a difference in the altitude of the maximum aerosol concentration between the model and the in situ profile after Calbuco eruption in April 2015. A particular focus is also made on recent eruptions like Raikoke, Ambae and Ulawun. The plume of the Ambae volcano (15°S, 167°E) which erupted in July 2018 is shown to propagate to the northern hemisphere with some influence until summer 2019 in the Asian monsoon region. For the year 2019, we investigate how the Ulawun (5°S, 151°E; ~0.14 Tg of SO2) tropical eruption and the Raikoke mid-latitude eruption (48°N, 153°E; ~1.5Tg of SO2), have influenced the aerosol burden in the tropics.


Optically transparent chitin nanofiber composites were fabricated with 11 different types of (meth)acrylic resins. Chitin nanofibers significantly increased the Young's moduli and the tensile strengths, and decreased the thermal expansion of all (meth)acrylic resins due to the reinforcement effect of chitin nanofibers having an extended crystal structure.


A Reissner's mixed variational theorem (RMVT)-based finite rectangular prism method (FRPM) is developed for the three-dimensional (3D) analysis of sandwich functionally graded material (FGM) plates subjected to mechanical loads, in which the edge conditions of the plates are such that one pair of opposite edges is simply supported and the other pair may be combinations of free, clamped or simply supported edges. The sandwich FGM plate considered consists of two thin and stiff homogeneous material face sheets combined with an embedded thick and soft FGM core, the material properties of which are assumed to obey the powerlaw distributions of the volume fractions of the constituents. In this formulation, the plate is divided into a number of finite rectangular prisms, in which the trigonometric functions and Lagrange polynomials are used to interpolate the y-direction and x− ζ plane variations of the primary field variables of each individual prism, respectively. Because an h-refinement process is adopted to yield the convergent solutions in this analysis, the prism-wise either linear or quadratic function distribution through the x−ζ plane is assumed for the related field variables. A unified formulation of these FRPMs with freely-chosen orders for assorted field variables is presented. It is shown that these quadratic FRPM solutions of simply supported, multilayered composite plates and sandwich FGM ones are in excellent agreement with the exact 3D solutions available in the literature, and those of multilayered composite plates with various boundary conditions closely agree with the solutions obtained using the ANSYS commercial software.

Objective To investigate the effect of methyl cellulose sedimentation on the isolation efficiency of mononuclear cells(MNCs) from umbilical cord blood(UCB) by density gradient centrifugation. Methods Two umbilical cord blood samples with equal volume from the same donor were isolated by Ficoll one-step isolation and methyl cellulose-Ficoll two-step isolation,respectively. The total amount of MNCs was calculated by direct cell counting under inverted microscope,and the cell viability was assayed by trypan blue negative counting. Furthermore,the percentages of hematopoietic stem cells(HSCs) and natural killer(NK) cells in the UCB MNCs were determined by flow cytometry. Results There was no significant difference in either MNC separating efficiency or cell viability between Ficoll one-step isolation and methylcellulose-Ficoll two-step isolation. Compared with one-step isolation,the two-step method achieved a similar number of CD34+HSCs,while a higher percentage of CD56+,CD3-CD56dimand CD3-CD56bright NK cell subpopulations in the UCB MNCs. Conclusion Methylcellulose sedimentation has no influence on the yield,cell activity and HSC frequency of MNCs from UCB isolated by density gradient centrifugation method,and it is helpful in keeping CD56+NK cell subpopulations in the umbilical cord blood.


A research in "MF-3D" field under Pre Stack Depth Migration method for 3D seismic reflection data has been carried out. PSDM selected to describing to perfect subsurface structure that obtain. This research aimed to applying initial interval velocity model determination method in PSDM to obtain better imaging subsurface structure with lateral velocity variation. Initial interval velocity model determination method which used was Dix Transformation and Constrained Velocity Inversion (CVI). Velocity model is quite sufficient to determining interval velocity in shallow layer and inclined flat under Dix Transformation. However, Dix Transformation precisely obtains less sufficient and unstable interval velocity in deeper subsurface layer. CVI conducted to determining initial interval velocity model which required to obtaining better and stable interval velocity in deeper subsurface layer. Both models required to obtaining initial model of 3D seismic section in depth domain as PSDM result. That model will get correction by using Horizon Based Tomography Algorithm in further step. This research yields initial 3D interval velocity model as input for PSDM process. Key Word: Pre Stack Depth Migration (PSDM), Constrained Velocity Inversion (CVI), Horizon Based Tomography

Background: Coronary heart disease is a major cause of mortality in chronic obstructive lung disease (COPD). During exacerbation of COPD, significant elevation of troponin has repeatedly been reported; however, a clear causative attribution is still lacking. Aims: We took aim at correlating raised troponin I in patients with exacerbated COPD with coronary angiographic results. Methods: In this prospective study, we enrolled 59 patients (73.6±9.2 yrs, 57.6% male), hospitalized for exacerbation of COPD and simultaneously offering a raise in troponin I ≥0.05ng/ml at admission. Coronary angiography was performed within 72 hours after hospitalization, and was complemented by transthoracic echocardiography and pulmonary function testing. Results: Pulmonary function testing revealed moderate to severe airway obstruction with a mean FEV1 and RV of 44.5±12.9% and 195.4±68.8% predicted, respectively. 91.5% of patients were current or former smokers (mean: 41.7 pack-years). Mean serum troponin I level averaged 1.73±3.78ng/ml. Echocardiographically assessed mean left ventricular ejection fraction accounted for 51.4±12.7%; 20 patients offered regional wall motion abnormalities. Coronary heart disease was angiographically evidenced in 42 patients (71.2%), of whom 24 patients (40.7% of total study population) showed necessity for and underwent percutaneous coronary intervention. Conclusions: Raised troponin in acute exacerbation of COPD is indicative of concomitant coronary heart disease and occurs – in a considerable proportion of patient – in consequence of myocardial infarction, requiring coronary intervention.


Soil nutrients are important parameters for maintaining the plant growth. Conventional in-situ methods are usually labor-intensive, low efficiency and time-consuming. Conversely, spatial interpolation is an extremely efficient method to derive the spatial distribution trend from discrete ground truth data. In this study, a total of 402 sample data of soil nutrients was collected in the wheat fields of Tongzhou District, Beijing, China. Slowly available potassium (SAK) was used as the interpolation factor. Four methods were comparatively employed to evaluate the availability and accuracy, specifically including inverse distance weighted (IDW), ordinary kriging (OK), spline function (Spline) and Trend interpolation. There are three models of OK, spherical model, exponential model and Gaussian model. Cross-validation was performed to compare the interpolation accuracy using the mean error (ME) and root mean square error (RMSE). The results show that OK is superior to the other methods, in which the exponential model is the best. In comparison with spherical function and Gaussian function, exponential model has the best performance with the ME and RMSE of 176.7084 and -1.1283, respectively.

We examine the price dynamics in Indian cities using cointegration analysis. We identify and then calculate a common trend for prices in these 25 cities. We obtain the impulse response functions to calculate the rates of convergence to the prices, and find that the half-life of any shock is very small for Indian cities. Although a close to three-month half-life seems too fast, there are some indications in the literature that half-life can be much smaller. We also analyzed how shock can be transmitted from one city to another and found no systematic behavior of price convergence. JEL Classification Code: F15, E31, C23.


Acute ischemic stroke remains one of the leading causes of morbidity and disability worldwide. The underlying cause is arterial occlusion, which might be cardioembolic because of atrial fibrillation or valvular heart disease, or arterioembolic because of atherosclerosis in the carotid artery or cerebral artery. Currently, effective reperfusion treatment includes intravenous thrombolysis with recombinant tissue plasminogen activator (rtPA), which degrades fibrin within the thrombus, or endovascular mechanical thrombectomy, which involves the removal of thrombus with stentretriever devices with the help of advanced imaging techniques. Although both treatments provide standard care to patients with thromboembolic stroke, each of them has strengths and limitations. For example, the strength of intravenous thrombolysis is that it can be applied to a wide spectrum of stroke patients. Unfortunately, however, it exhibits only a modest effectiveness.1 Early arterial reocclusion and unsatisfactory longterm outcomes were observed in approximately 30% of stroke patients after rtPA administration.2 In addition, successful recanalization is less often achieved in patients with largevessel occlusion.3 Other limitations include increase risk of hemorrhagic transformation and the narrow therapeutic window of up to 4.5 h for starting tPA reperfusion from the stroke onset. Beyond this timeframe, most admitted stroke patients are not suitable for reperfusion therapy, which substantially limits the eligible population.4 On the other hand, although endovascular mechanical thrombectomy is much more efficacious, it can only be applied in a small subset of patients with a stroke caused by a largevessel occlusion.5 Nearly 50% of treated acute stroke patients with largevessel occlusion still experience neurological deficits after thrombectomy.6 Furthermore, some patients are not eligible for mechanical thrombectomy because of larger infarcts that cannot be salvaged.7 Another constraint is that mechanical thrombectomy requires skilled interventional neurologists, not immediately available at all the hospitals. These shortcomings of rtPA and mechanical thrombectomy call for a compelling requirement to develop novel therapeutic interventions that can protect the stroke penumbra, reduce the size of infarct core and may offer better neurological outcomes if administered as early as possible following stroke onset.


The author describes recent fertility trends in England and Wales.

There are surgical and conservative treatment options in Mallet Finger deformity in accordance with the shape, degree and place of the damage (3). Although there are various treatment options for Mallet Finger deformity, optimal treatment is still unclear. The first option for conservative treatment is splinting and exercise (3, 4). Surgical treatment options for primary bone fragment ruptures include open or closed reduction and K-wire fixation; if there is a long enough tendon part in the distal, tenorrhaphy or fixation of the tendon with pull-out techniques in avulsions close to the bone is also preferred. Secondary interventions are tendon plication or arthrodesis (5). Although primary treatment is satisfactory, secondary treatment approaches are not evenly successful in neglected cases (6).


In the past 35 years, over 300 studies have examined interrelationships between psychological factors and recurrent headache—a testament to the importance of the content area of this book. Directed toward a broad readership (ie, neurologists, family practitioners, internists, and social workers), this volume's 33 brief chapters provide an introduction to a variety of issues pertaining to psychological factors and headache. This edited volume is divided into five sections including conceptualizations of headache, assessment, psychiatric aspects of specific headache syndromes, psychobiology of stress and headache, and treatment. We agree with the editors in their acknowledgment that this work was an ambitious undertaking; despite their valiant effort and partial success, we found the book lacking in several important respects. Perhaps our most critical concern is the tendency for a number of the chapters to unnecessarily characterize the average headache patient in psychopathologic terms. Although the editors preface this volume with a disclaimer

Quick diagnosis of H5N1 infection in cats is important because of the zoonotic and pandemic potential of this virus. Human rapid influenza antigen tests are also sold commercially to veterinarians for use in cats. The point-of-care test actim(trade mark) Influenza A&B (Medix Biochemica, Kauniainen, Finland) was evaluated for the diagnosis of H5N1 infection in cats. The test showed a very low sensitivity and did not detect virus in samples of experimentally infected cats, so that its application cannot be recommended for the diagnosis of H5N1 infection in cats.

Congestion occurs when resource demands exceeds the capacity. At this moment, congestion are solved by the involvement of two controlling mechanism, they are flow control in the TCP source and active queue management (AQM) in the link. AQM will provide feedback to the source a kind of indication for the occurrence of the congestion in the link, whereas the source will adapt the sending rate appropriate with the feedback. The indication of the feedback congestion is influenced by the number of the sources, time delay, and its sending rate. Consequently, adaptation of the sending rate based on the feedback indirectly observes behavior of other sources. This control system structure is much known with distributed control system, because the control mechanism is distributed in each source. On this structure, the source mechanism is more important than the link. This paper will explain a new algorithm, which focus more on the link as an allocation capacity controller. Then the source will adapt the sending rate based on set point the link provides


lost before it could be identified antigenically. Acc. 270-38. On September 13, 1944, a sklewinder (C. cerastes) died. It was very poor, the rectum was congested, and the liver was studded with minute abscesses. It had been in this cage since September 1, 1943, and had not eaten for almost a year. Type 10 was recovered from the heart blood, lungs, liver, kidneys, and intestine. 270-46. On November 8, 1944, a male sidewinder rattlesnake (C. cerastes) died. It had been in this cage only a short time. It was poor, the heart was flabby, and there were numerous cysts in the abdominal cavity. No paracolon types were recovered. 270-53. In April, 1945, two feces samples were taken from this cage, which by then had only two survivors in it. Paracolon types were not recovered; Pseudmonas strains predominated in both specimens. A total of 15 snakes have been autopsied for the San Diego Zoo since 1942. Seven of the 15 were rattlesnakes from this cage (A-31). Paracolon type 10 was isolated from at least 4 of these. A paracolon strain isolated from a fifth snake was not identified antigenically; biochemically it was similar to the others. Feces from this cage, cultured in 1943, also yielded type 10 paracolon. There are several facts which show the relationship of the isolations from these snakes to paracolon type 10 infection of turkeys. This cage was always kept as an exhibit of snakes caught in San Diego County or adjoining territory. This is the only cage which suffered epidemic losses, and the only one from which this paracolon type was recovered. The losses caused by this type in turkey poults referred to above were also confined to this area, and rattlesnakes were present on at least two of the turkey ranches from which this type was isolated.

In 2012 two historical novels were published, one by Kinneret Zmora-Bitan Dvir publishing house in Israel and one by Penguin group in the USA. The one was written in Hebrew and the other in English. I doubt if one author knew of the other or shared her work and ideas with the other, but I identify in the two a literary and historical trend that unites in it the culmination of a long process within rabbinic studies which I would like to outline and characterize. The books are אביקע לש סדרפה by Yochi Brandes1 and Rav Hisda's Daughter by Maggie Anton.2 The authors I am interested in come from completely different backgrounds: Brandes was born in a haredi home in Israel, daughter of a Hassidic admor and while holding on to her Jewish identity, has worked hard on releasing herself from the authoritative environment in which she grew up.3 First she shed her religious garb and turned secular and leftist in her views. Then she went to university. In order to do this she underwent a complex psychological and intellectual transformation, where much of the conventional wisdom about women and their role in society, which she received at home, would have had to be discarded. Anton, on the other hand, grew up in a secularsocialist house in California, and was drawn to her Jewish roots at a later stage in life.4 She too, would have had to undergo a transformation in her understanding of her identity and heritage. She has become a synagogue going woman, and a practicing Jew. Both women share, however, in what can be defined as nothing less than a scholarly revolution which, at the end of the

EUV lithography is expected to be an important technology for manufacturing 22 nm node and beyond in the semiconductor industry. To achieve the desired resist RLS performance for such fine feature patterns, multilayer materials are almost certainly needed to define the overall lithography process. The resist modeling and experiment studies suggest high EUV absorbance of the film improves resolution, line width roughness and sensitivity. In this paper, we report the studies of new EUV underlayers (EBL) based on crosslinkable organic underlayer materials with high EUV photon absorption (EPA) unit. The lithography results for the new EUV underlayer materials have demonstrated advantages over conventional organic underlayer in terms of resist sensitivity, resolution, process window, pattern profile, collapse margin, and possibly line width roughness.


Intracluster light (ICL), coming from stars between the galaxies, has been found to be common in galaxy clusters (Feldmeier et al. 2004; Mihos et al. 2005; see Arnaboldi et al. 2009 for a recent review). However, the amount of intragroup light (IGL) is much less well known. Theoretical studies (Fig.1; Purcell et al. 2007) indicate a systematic rise in IGL fraction as systems increase in mass from individual galaxies, through galaxy groups up to galaxy clusters. Unfortunately, thus far observations of IGL in normal galaxy groups have been unsuccessful. The amount of IGL found in compact groups of galaxies, where the extreme galaxy density promotes many tidal interactions, is much larger, but there is considerable scatter in the observations thus far (Fig 2).


Sigma-1 receptor (Sig-1R) is a class of orphan receptors, the potential role of which in pancreatic islet cells remains poorly understood. The present study aimed to investigate the role of Sig-1R in islet β-cell proliferation and examine the effects of Sig-1R on islet β-cell injury under lipotoxic conditions. Sig-1R-overexpressing MIN6 cells were generated by lentiviral vector transfection. The effect of Sig-1R overexpression on cell proliferation detected by EdU staining, cell cycle progression by propidium iodide (PI), apoptosis by Annexin V-APC/PI, mitochondrial membrane potential by Mitolite Red and cytoplasmic Ca2+ levelsby Fura-2/AM in islet β-cells were measured by flow cytometry. Western blot analysis was used to measure protein expression levels of endoplasmic reticulum (ER) stress markers glucose-regulated protein 78 and C/EBP homologous protein, mitochondrial apoptotic proteins Bcl-2-associated X and Bcl-2 and cytochrome c. In addition, ATP levels and insulin secretion were separately measured using ATP Assay and mouse insulin ELISA. Mitochondria-associated ER membrane (MAM) structures in MIN6 cells were then detected using transmission electron microscopy. Protein disulfide isomerase expression and possible colocalization between inositol 1,4,5-trisphosphate receptor and voltage-dependent anion channel 1 were examined using immunofluorescence. Sig-1R overexpression was found to promote β-cell proliferation by accelerating cell cycle progression. Furthermore, Sig-1R overexpression ameliorated the apoptosis rate whilst impairing insulin secretion induced by palmitic acid by relieving ER stress and mitochondrial dysfunction in MIN6 cells. Sig-1R overexpression also promoted Ca2+ transport between mitochondria and ER by increasing the quantity of ER adjacent to mitochondria in the 50-nm range. It was concluded that Sig-1R overexpression conferred protective effects on β-cells against lipotoxicity as a result of the promotion of cell proliferation and inhibition of ER stress and oxidative stress, by regulating the structure of MAM.


Regeneration of a complex appendage structure such as limb requires hierarchical coordination of multiple types of tissues. Muscles, as one of the major cell masses in limbs, have been reported recently to be critical to guide other tissue regeneration in planaria, but its function and relationship to other cells in vertebrate complex regeneration have been unclear. Here, we use Pax7 mutant axolotls, in which the limb muscle is developmentally lost, to investigate limb regeneration in the absence of skeletal muscle. We find that the pattern of regenerated limbs is normal in Pax7 mutants compared to the controls. Lack of muscles do not affect the proliferation of fibroblasts, another major population in limbs. Furthermore, using single cell RNA-sequencing, we demonstrate that the cell type composition in completely regenerated limbs in Pax7 mutants is similar to that in the controls, except the lack of cell types in muscle lineage. Our study reveals skeletal muscle is not required for the guidance of complex tissue regeneration in axolotls, and provides new views of the tissue hierarchy in vertebrate appendage regeneration.


Long-term acceptance rates (LTAR) are used in specifying the area of the bottom of drainfield trenches required for onsite wastewater systems (OWSs). Our objective is to present • simple method for converting soil saturated hydraulic conductivity (Ks) to LTAR, given • number of assumptions about soil and biomat hydraulic properties. In this paper, we describe an Excel spreadsheet that uses a modified equation from Bouma (1975) to calculate the steady trench bottom flux in an OWS based on an input of soil K. The soil water retention parameters are also required, but they can be taken from a table in the spreadsheet that provides parameters for the 12 USDA soil textural classes on the basis of the Rosetta database. Biomat thickness and saturated hydraulic conductivity are also required, and values are suggested in the spreadsheet. Bottom flux as a percentage of K . varied widely from 52% in the silt loam class to 2% in the sand class. To convert steady bottom flux to LTAR, a safety factor should be used, and we suggest that LTAR should be one-half of the steady bottom flux. Using these assumptions we calculated LTAR for 12 USDA soil textural classes. The LTAR ranged from 1.48 cm d(0.36 gal d 1 ft2 ) for the sandy clay class to 5.40 cm d1 (1.32 gal d ft -2) for the silt class. D rainfield trenches in on-site wastewater systems (OWSs) are used to distribute septic tank effluent and allow it to infiltrate into the soil. Studies have shown that the wastewater infiltration rate in drainfield-trench interface that impedes infiltration and causes ponding in the trench. An estimate of the final steady wastewater infiltration rate is needed to specifying the area of the trench bottom required for onsite wastewater systems (OWSs). This rate is commonly referred to as the Long Term Acceptance Rate (LTAR). Although the rate is more properly called the Design Hydraulic Loading Rate (HLR0), which only considers hydraulic loading and does not consider biological and chemical treatment of pollutants, we will use the more common term of LTAR. Estimates of the LIAR are often made based on identification of the soil series or texture, structure, and/or mineralogy of the soil horizons. In some cases, measurements of soil K are made, especially if the soil is a borderline case for suitability. In this case, a method is needed for converting K to an estimate of LTAR. Radcliffe and West (2008) used the HYDRUS (imünek et al., 2006) two-dimensional computer model to determine the steady flux through the trench bottom for the 12 USDA soil textural classes with 5 cm of wastewater ponded in the trench as an estimate of the performance under normal operating conditions. We also tested how well a D.E. Radcliffe, Professor, Crop and Soil Sciences Dep., University of Georgia, Athens, GA (firstname.lastname@example.com ); L.T. West, National Program Leader—Soil Survey Investigations, USDA-NRCS, National Soil Survey Center, Lincoln, NE. Published in Soil Surv. Horiz. 50:20-24 (2009). simple equation developed by Bouma (1975) estimated the bottom flux To estimate the LTAR, we took 50% of the steady trench bottom flux as a safety factor. Despite the wide range in K of the soil textural classes (8.18-642.98 cm d 1 ), the steady flux through the bottom of the trench in these soils fell in a narrow range of 2.64 to 16.54 cm d 1 . With a modification to account for unsaturated flow within the biomat, the Bouma equation produced very similar estimates of trench bottom flux for all soil textural classes to those found using HYDRUS. Our objective here is to describe an Excel spreadsheet we developed based on the modified Bouma equation that can be used to convert soil K to an estimate of LTAR, given a number of assumptions about soil and biomat hydraulic properties. Methods In the approach developed by Bouma (1975), it is assumed that the flux at the trench bottom through the biomat will be equal to the flux through the soil just beneath the biomat at steady state: Qb = Kbs hohs+ZbK(h) Zb where Qb is the flux through the biomat (cm d) and Q is the flux through the soil just beneath the biomat. The flux through the biomat (0b) is described using a form of the Darcy equation (left-hand side of Eq. [2]: a 20 SOIL SURVEY HORIZONS tural class in the Rosetta database for all calculations. However, they can be easily changed in the spreadsheet (e.g., to have the same values [2] as the soil). Q Os h0 h3 + Z,, Kbs =K(h) __-Z that includes the saturated hydraulic conductivity of the biomat (Kb) (cm d -'), h0 is the height of water ponded in the trench (cm), fri is the negative pressure head in the soil just beneath the biomat (cm), and Z, is the thickness of the biomat (cm). The flux through the soil (right-hand side of Eq. [11) is equal to the unsaturated hydraulic conductivity of the soil [K(h1)] (cm d-) (right-hand side of Eq. [2]) because the approach assumes that there will be a unit gradient in pressure heads beneath the biomat. To solve Eq. [2], the value of h that makes both sides of the equation equal has to be found. Since h1 appears in two places and the equation cannot be solved explicitly for h, an iterative procedure has to be used. The modified Bouma equation developed in Radcliffe and West (2008) differs in the way the hydraulic conductivity term for the biomat is described: 1 ho_-hs+ZbK(h) 5 Zb 1/[5Kb(hj)] 1=1 To accurately represent the biomat hydraulic conductivity, the biomat is divided into five layers. The Kb(h) is the unsaturated hydraulic conductivity of the biomat in each of these layers at pressure heads h, with i= 1 t 5. The values for hare calculated using a parabolic equation with a value of h0 at the top of the biomat and a value of h at the bottom of the biomat: h1 = hh0 .[.(j_1))2 +h0 [4] The unsaturated hydraulic conductivity functions in Eq. [3] [K(h) and Kb(h)] are described by the van Genuchten (1980) equation: The other secondary input variables are the biomat thickness (Zb in cm), biomat saturated hydraulic conductivity ( Kbl in cm d'), and height of water ponded in the trench (h0 in cm). Estimates of biomat Z, and K1 are provided in the spreadsheet based on a study by Finch et al (2007) of seven OWSs in Georgia (K b, = 0.23 cm d' and Zb = 0.5 cm). The spreadsheet assumes the depth of ponding in the trench to be 5 cm. This value was chosen to simulate the shallow ponding one might expect under normal loading of the OWS, reserving most of the sidewall and trench volume for peak flows under abnormal loading as suggested by Siegrist (2007) To convert the trench bottom flux to an estimate of [TAR, a safety factor must be chosen. The suggested value for the safety factor in the spreadsheet is that estimated LTAR should be one-half of the steady trench bottom flow. As such, a user can specify the input soil 1(1, take the water retention parameters from the table for the appropriate textural class, and calculate LTAR if they are willing to accept the suggested values for biomat properties, safety factor, and depth of pending. Otherwise, users can specify their own values for water retention parameters, biomat properties, safety factor, and depth of ponding. To illustrate the use of the spreadsheet, we used an example in which <1 and the textural class were known and the spreadsheet was used to estimate LTAR. We also calculated steady trench bottom flux and LTAR for the 12 USDA soil textural classes in the Rosetta database. This database includes records from more than 2000 soils for water retention and more than 1000 soils for K1 . The values taken from the Rosetta database are shown in Table 1. We performed a sensitivity analysis where we varied the biomat properties and the height of ponding to see the effect on trench bottom flux.

Improving the energy densities of secondary batteries has always been the core goal of scientific research and engineering development. In this paper, by testing the energy densities of the test samples, the gravimetric energy density (GED) and volumetric energy density (VED) of Li-ion and Li-metal batteries are analyzed. By comparing with the development trend of batteries at home and abroad, we can see that Li-metal batteries are the development direction of high-energy-density batteries in the future. By comparing the test results of this paper with the energy densities data published at home and abroad, we can see that the GED and VED of Li-ion and Li-metal batteries in China have reached the international advanced level. The research results of this paper can basically reflect the development status and provide guidance for the development of high-energy-density batteries in China.


This is a case report of a 72-year-old woman under oral anticoagulation who presented in the emergency room with a subacute onset of left-accentuated lumboischialgia, a left-side foot drop, a foot plantar flexion palsy and an eversion weakness. Other clinical findings included an abscessing parotitis and an oligoarthritis of unknown aetiology. The neuroradiological evaluation with computer tomography and myeloradiculography did not show any adequate spinal or radicular affection. A complete left-leg palsy and increasing sensory deficits developed during the early course of the hospitalisation. A pelvic CT was performed and revealed a left-sided retroperitoneal mass lesion with compression of the sacral plexus and the ischiadic nerve. CT-guided puncture resulted in the diagnosis of a haematoma infected with Staphylococcus aureus. We considered this process to be induced by the anticoagulant treatment and secondary septic dissemination from the parotid abscess. Percutaneous drainage and antibiotic treatment resulted in fast clinical recovery of the motor deficits; however, mild sensory residues persisted. Our case report demonstrates the necessity to consider for possible extraspinal lesions also in patients presenting with the typical symptoms of radicular compression, particularly when the initial evaluations were not conclusive.


China's Yangtze River Delta region has banned the approval of new thermal power projects except for combined heat and power (CHP) generation and is promoting technological innovation in CHP. However, technological innovation of energy technology has been evidenced to be often affected by spatial elements. The role of spatial agglomeration in the energy industry on technological innovation has not been discussed in the context of CHP. Therefore, this article studied the spatial agglomeration and evolution characteristics of CHP technological innovation point elements through the Global Moran's index, kernel density analysis, and thermal map analysis and analyzed the influencing factors and changes by the spatial regression model. The results show that environmental regulation and high-tech park agglomeration are the key factors influencing CHP technological innovation. This indicates that future policy making needs to consider the economic factors of green development and the role of high-tech parks in innovation.


Background Changes in trunk angle as part of modifying the seated cable row exercise (MSCRE) are associated with trapezius muscle activity and ratio. Purpose This study aimed to determine the changes in muscle activity and ratio for the upper trapezius (UT), middle trapezius (MT), and lower trapezius (LT) muscles during the MSCRE in healthy participants without shoulder pain. Study design Cross-sectional study Methods We included participants who were 23 healthy individuals aged 23–39 years. The participants performed a pulling motion three times during the MSCRE at each of the following trunk angles: upright posture 0˚, forward lean 30˚, and backward lean 20˚. Surface electromyography was performed for the UT, MT, and LT muscles during the 5-s isometric contraction, with the participant in a preset position, while the muscle activity was normalized with the maximal voluntary isometric contraction using the manual muscle test. Results The UT and LT muscle activities showed significant differences in angle ( p <0.05); the highest muscle activity was observed for the UT at backward lean 20˚ and LT at forward lean 30˚. The UT/MT and UT/LT ratios showed significant differences in angle ( p <0.05), with the highest values observed at backward lean 20˚ for both the ratios. Conclusions These results suggest that the forward lean 30˚ trunk angle was most suitable for the MSCRE in the selective strengthening of the LT muscle, indicating that the trunk should be tilted forward during exercise for normal and balanced recovery of trapezius muscle activities in shoulder rehabilitation.

Features, technical implementation and future development are described in this positioning paper.


Managed care's promises of improved cost efficiency and continuity of care to the general population are being tested by the higher demands of Medicare and Medicaid populations, including many chronically ill individuals. By examining and comparing satisfaction among chronically ill and healthier enrollees and between Medicaid and non-Medicaid enrollees, the authors develop an understanding of how satisfaction among the chronically ill provides assessments that are important to all enrollees. The authors examine public policy initiatives in the context of the special needs of the chronically ill to determine whether the initiatives are likely to help generate improvements with respect to aspects of care and access that are most important to the chronically ill and ultimately to enrollees in general.


Purpose The investigation of the different plant waste parts for ecofriendly management of Fusarium sp. was carried out.
Method The disease associated fungus was isolated from the diseased specimen and purified. The twelve different aqueous plant extracts were prepared and evaluated against test pathogen in laboratory, pots and in filed conditions.
Results Among the tested aqueous plant extracts the neem seed, thorn apple, garlic, neem leaves and eucalyptus were found the most effective providing highest growth inhibition percent of test fungus. The lowest plant mortality and disease incidence percent, maximum plant biomass and minimum root infection percent were observed in plans treated with neem leaves, neem seed, garlic, thorn apple and eucalyptus extracts in pot experiment. In field experiment, the extracts of neem leaves, thorn apple and neem seed produced the lowest disease incidence and mortality percentage as compared to other extracts. The extract of garlic was noted as moderate effective among the treatments. The eucalyptus extract was found as less effective. The maximum height and weight of individual plant was observed in the treatment of neem leaves than in neem seed, garlic, eucalyptus, and thorn apple extracts. Significantly, the highest fruit yield was recorded in plant treated with neem leaves extracts followed by neem seed, garlic, eucalyptus, and thorn apple.
Conclusion The study showed that neem leaves, neem seed and garlic, eucalyptus and thorn apple extracts are potential aqueous extracts for ecofriendly management of tomato fusarium wilt disease.


Operating Systems is a discipline which handles abstract concepts and techniques. However, most of OS courses have been textbook-oriented theoretical classes. Theoretical classes lead to the decline in the understanding of a lecture, and hurt their concentration. Many instructors have tried to make use of educational tools to help students understand lectures and arouse interests. This paper describes the design and implementation of a CPU scheduling simulator which shows the operation of process scheduling algorithms visually. The academic achievement evaluation for 2010's students and 2011's and t-test results show that the differences of the correct answer ratio for the exam about CPU scheduling algorithms are meaningful. The survey shows that the simulator is useful as an educational tool which causes the interests and enhances the understanding of a lecture, this teaching method is effective to develop problem solving skills.

Introduction: Atrial fibrillation is the most common arrhythmia with significant morbidity and mortality. Radiofrequency (RF) ablation, despite its shortcomings, remain an acceptable and 'simple' technique. Methods: We reviewed 137 consecutive concomitant irrigated RF modified maze procedures, and compared the outcomes of 65 patients undergoing Unipolar-RF versus 72 patients using the combined Uni/Bipolar-RF approach. All patients were prospectively followed clinically, with serial electrocardiography and selective echocardiography. One hundred and twenty-two patients (89.1%) underwent mitral valve procedures, and eight coronary bypass, and seven adult congenital operations were performed. Results: The predominantly male (54.7%) patients had a mean age of 58.3±11.5 years (23–88 years). At median follow-up of 3.21 years (0.01–6.06 years), 15 (10.9%) patients were lost to follow-up. Freedom from AF in the Uni/Bipolar-RF group was higher at six months: 85.1% (57/67) versus 65% (39/60) in the Unipolar-RF group (P=0.012). This superior trend persisted at five years: 100% (5/5) in the Uni/Bipolar-RF group versus 79.5% (31/39) in the Unipolar-RF group, although this is not statistically significantly (P=0.566). Patients with left atrial dilatation beyond 7.6cm were more likely to remain in AF (OR 0.44, 95% CI, 0.19–1.00, P=0.049). Perioperative mortality was 2.9%. There was no collateral damage by the device and procedure. The mean survival for patients AF-free at last follow-up is 5.73 years (95% CI, 5.48–5.98), comparable to 5.58 years (95% CI, 5.07–6.10) in those remaining in AF. Thirty (22.6%) patients were completely off anti-arrhythmic medication while 36 (25.6%) were anticoagulant-free. Conclusion: The combined Uni/bipolar-RF modified bi-atrial Maze technique is simple, safe and superior to isolated Unipolar-RF ablation. Midterm results continue to support its use although long-term durability remains to be elucidated.


When x‐rays are scattered from a thin crystalline surface film overlying a crystalline base material, diffraction lines are observed from both materials. Equations are developed for the general case of (1) a flat sample and (2) a cylindrical sample expressing the ratio of line intensities from the two materials as a function of film thickness. A usable range of 10−6 cm to 5×10−2 cm is indicated. Experimental confirmation is found in the range 10−4 cm to 6×10−3 cm.


The purpose of this study was to explore the institutional protection scheme to identify the factors influence physician turnover of social workers. The main reference comes from the 2014 research on wages and work conditions of Korea Institute for Health and Social Affairs. The result of the analysis shows that 33.7% of the social workers intend to change jobs and that the possibilities of changing jobs have factors in gender, age, education levels, job satisfaction, wage, and contractual factors. This result shows that in order to enhance support of underprivileged, the treatment of social workers needs to be improved. This research proposes settings of switching job position system through facility M&A and institutional development.

Significance: Deuterium-labeled chiral compounds can be excellent tools for probing reaction mechanisms. Commonly used strategies for their synthesis include the use of chiral auxiliaries in stoichiometric quantities (J. Haesler et al. Nature 2007, 446, 526). The authors present an asymmetric zirconium-catalyzed carboalumination. Following ee upgrades by lipase treatment, deuterium was incorporated to generate cryptochiral molecules (G. Zhang et al. J. Am. Chem. Soc. 2006, 128, 6026). Comment: The products of the zirconium-catalyzed reaction were produced in modest ee's (80– 88%), which were then upgraded to >99% ee by lipase treatment. Introduction of deuterium was accomplished by treatment with LiAlD4 or via copper-catalyzed cross-coupling. The enantiomeric ratios were determined via Mosher's method (see recent Review below).


The article describes the factors, conditions, the principle of communicative activity (as a component of the principle of activity), signs, opportunities in creating conditions for the development of many areas of the student's personality, goals, objectives, content and forms of extracurricular activities. A systemically organized extracurricular lesson includes methods of teaching, upbringing and development that stimulate students to master knowledge and skills on their own, and also disposes to more informal interaction with teachers, which leads to the disappearance of the framework of the formal relationship and the disclosure of the internal potential of students.


Standard frequency converters (FCs) are evaluated in this work as a universal solution for photovoltaic (PV) water pumping systems. FCs can be connected directly to a PV generator to power centrifugal submersible pumps driven by three‐phase asynchronous induction motors. In comparison with dedicated products, the use of standard FCs and centrifugal motopumps encompasses several advantages: power range, broad range of products and technological independence. This paper describes the main rules to implement standard FCs in PV pumping systems, and presents a model to estimate its performance from standard pumps manufacturers' data. The experimental validation of the model is also presented. Copyright © 2003 John Wiley & Sons, Ltd.


A theoretical approach of an ultra lightweight sandwich composite structure with extreme rigidity is presented. The structure features two carbon/epoxy skins reinforced with twill weave fabric, and an expanded polystyrene (EPS) core. The structure is subjected to a biaxial field of normal loads combined with a shear load. An equivalent model of this structure is presented. It has been accomplished a comparison between this structure and a similar one with glass/epoxy skins reinforced with EWR-300 fabric. Sandwich structure's strains, stresses, skins plies' strains and a comparison between the rigidities of the structure's components are presented. A theoretical approach regarding the bending of the structure is also shown.

This article examines the interplay between distance and proximity through the maritime medium of the Mediterranean, today rendered immediate by the 'foreign' body of the migrant. What until recently was maintained at a physical and metaphysical distance: colonialism, racial hierarchies and historical amnesia, has suddenly acquired a dramatic presence with an alarming proximity. This postcolonial return operates a cut in the existing epistemological fabric. Understandings of space and time are radically reconfigured. Refused archives emerge. Other genealogies of the present enter the frame. The legal and political premises of Occidental modernity, together with the very idea of liberal democracy and rights, are violently exposed in their brutal limits. In this scenario distance and proximities are measured through mediations drawn from the area of contemporary art and visual culture; these evoke critical considerations on the limits of representation and the politics of registration.


SINCE 1977, when he shifted the focus of his earlier production, Allan McCollum has been involved in an investigation of the work of art with regard to its function within the social system. 'If one wants to understand art,' McCollum has stated, 'it seems to me, one should begin with the terms of the situation in which one actually encounters it'.1 To this end, the artist has developed a diverse series of works that reflect upon the status of art in contemporary culture. Although their paricular means and emphasis necessarily vary, the Surrogates, Perpetual Photos, Perfect Vehicles, and Individual Works, created by McCollum during the last twelve years, call attention to the place of art as an economic and psychological, not merely physical, presence within society.


Fatigue cracking in steel girder web penetration details is so dangerous that it can break steel girders. Since a number of highway bridges with such web penetration details may exist in Japan, it is of urgent importance to grasp these fatigue strength properties. The purpose of this study is to clarify fatigue behaviour of steel girder web penetration details with a slit through fatigue tests of specimens which have steel girder web penetration details with a slit.


Phosphonates are water treatment chemicals that are effectively utilized in many industrial processes as dispersants, bleaching agents, or scale and corrosion inhibitors. In many of these applications, the phosphonates are able to react with divalent cations such as calcium to form stable divalent cation−phosphonate precipitates. The focus of this paper is to define the conditions under which distinct calcium−phosphonate precipitates will form and to study how each of these precipitate's unique chemical and physical properties govern the release of phosphonate from porous media. The phosphonate used in this study was (1-hydroxyethylidene)-1,1-diphosphonic acid (HEDP). By variation of the pH and calcium/HEDP molar ratio in solution, two distinct precipitates were formed:  (1) a soluble, fibrous 1:1 calcium/HEDP precipitate; and (2) a less soluble, spherical 2:1 calcium/HEDP precipitate. Critical pH values that define the conditions under which each distinct precipitate forms were identified. Below the firs...


The minimum bow force Fmin necessary to establish Helmholtz motion on stringed instruments was widely believed to be proportional to the bow velocity vB, to the reciprocal of the bridge resistance R, and to the reciprocal of the relative bow-bridge distance s squared [J. Schelleng, J. Acoust. Soc. Am. 53, 26-41 (1973)]. More recently, a study reported independence from vB and an overproportional reciprocal effect of R while confirming the 1/s² proportionality [E. Schoonderwaldt, Acta Acustica United with Acustica 94 604-622 (2008)]. Here, a bowing pendulum is used which facilitates precise control and measurement of related parameters. The string excitation at the contact point is recorded to instantly classify Helmholtz motion (HM) versus non-Helmholtz motion with one (nHM-1) or more slips during the stick phase. Monitoring of the classification supports the control of bowing parameters during measurement. These are directed towards the regions of transition between HM and nHM-1 to reveal the parameters ...


A systematic method for implementing parasitic-insensitive (PI) switched capacitor filters (SCFs) and digital filters (DIGFs) using systolic array architecture (SAA) is introduced. A signal flow graph (SFG) method is used for a general treatment of first and second order filters. Systematic reduction of the SFGs leads to a number of SAA implementations which will require minimal hardware. Practical aspects of implementation are discussed. Simulation results are reported.<<ETX>>


This paper proposes a novel bacteria foraging reinforcement learning with knowledge transfer method for risk-based economic dispatch, in which the economic dispatch is integrated with risk assessment theory to represent the uncertainties of active power demand and contingencies during power system operations. Moreover, a multi-agent collaboration is employed to accelerate the convergence of knowledge matrix, which is decomposed into several lower dimension sub-matrices via a knowledge extension, thus the curse of dimension can be effectively avoided. Besides, the convergence rate of bacteria foraging reinforcement learning is increased dramatically through a knowledge transfer after obtaining the optimal knowledge matrices of source tasks in pre-learning. The performance of bacteria foraging reinforcement learning has been thoroughly evaluated on IEEE RTS-79 system. Simulation results demonstrate that it can outperform conventional artificial intelligence algorithms in terms of global convergence and convergence rate.


The article deals with the issues of the practical application of industrial information system, namely, Enterprise Resource Planning (ERP) in the management of the economy of a diversified agro-industrial complex in the risk farming area. Features of ERP system application are considered taking into account both multidirectional activity of the agricultural enterprise (crop production, animal husbandry, and industrial production), and the complex system of taxation: the presence of a common taxation system and taxation of various activities. Particular attention is paid to the mechanism of closing accounts, and the formation of the actual cost in terms of agricultural production, which is not so much complicated as a laborious and routine task. A huge number of transactions, multiple calculations of the costs distribution bases, the complex structure of the divisions of the very enterprise make the task of automating of process closing period extremely important. The article presents the experience of both the use of ERP system and the training method of specialists in the use of such industrial information systems for automated accounting and management accounting, payroll and personnel accounting, tested at St. Petersburg State University. In consequence of the implementation of the algorithms described in the article, one managed to achieve an increase in both quantitative economic indicators of the agricultural complex, and qualitative indicators, related to the training of specialists in the field of application of ERP systems in agro-industrial complexes


Review on BCL7B (B-cell CLL/lymphoma 7B), with data on DNA, on the protein encoded, and where the gene is implicated.


High frequency radiation patterns of aircraft wing mounted antennas are analyzed. Basic antenna types using ray optical techniques are studied. The aircraft is modelled in its most basic form so that this study is applicable to general type aircraft. The fuselage is modelled as a perfectly conducting finite elliptic cylinder. The wings and horizontal and vertical stabilizers are modelled as perfectly conducting "n" sided flat plates that can be arbitrarily attached to the fuselage or to themselves. The antenna locations are assumed to be on the surfaces of the wings at locations removed from engines and stores such that these effects are negligible. Volumetric patterns are calculated for several aircraft. The validity of the solution is shown by comparing the results against scale model measurements. The application of this solution to practical airborne antenna problems has shown its versatility in designing antennas and predicting their radiation patterns in an accurate and efficient manner.


Jose C Martines and colleagues give some of the reasons why many breastfeeding mothers in developing countries supplement their milk with water or teas from the first week of life. Another important reason is the belief that such fluids have "inner cleansing" effects on their babies. In some societies and cultures the babys first drink is plain water. This may be a few teaspoonfuls or even fingertip quantities in drops. This initial drink is a symbol of welcoming the baby. Subsequently plain water or sugar and water are fed to the baby while the colostrum is discarded as unclean; breastfeeding is started when the milk becomes clearer after a few days. Water and teas are not regarded as supplements to breastmilk in the real sense being given at the beginning of the feed between feeds or at the end of the feed. This practice has stood the test of time and it will not be easy for health professionals to persuade mothers against it. As one of the main reasons for discouraging the practice is diarrhea in the babies due to dirty water perhaps the emphasis should be on the importance of giving clean water to infants. Surely all pregnant women should be informed how and why they should breastfeed. They should be taught that the inside of the baby is not dirty and that the passage of meconium is normal. If health professionals persuade rather than effectively educate these mothers not to give water to their babies the mothers might resort to other methods of cleaning the babys inside with enemas suppositories and purges which could be more dangerous.

We give a self contained and elementary description of normal forms for symplectic matrices, based on geometrical considerations. The normal forms in question are expressed in terms of elementary Jordan matrices and integers with values in {-1, 0, 1} related to signatures of quadratic forms naturally associated to the symplectic matrix. © European Mathematical Society.


Ti O2 were fabricated on electrospun polyacrylonitrile( PAN) nanofibers via the coupling of electrospinning process and hydrothermal treatment,and the resulted nanofiber mat has visible light induced photocatalystical properties. The surface of as-formed fibers containing Tetrabutyl titanate,gadolinium nitrate, PAN and polyvinylpirrolidone was smooth and the average diameter was about320 nm. Then the as-formed fibers were transferred into Teflon-lined stainless steel autoclave for hydrothermal treatment. The surface of the resulted porous fibers( the diameter is about 350 nm) was uneven and the Brunauer-Emmett-Teller( BET) surface area was 17. 45 m2/ g. XPS and XRD results showed that PAN fiber mats loaded with anatase( Gd / N-Ti O2) crystals have been produced. Finally,the resulted polymer-inorganic hybrid nanofiber mats exhibited obvious photocatalytic activity to degrade rhodamine B dye under visible light.

In practical grazing incidence measurements using a commercial interferometer, repeatability and accuracy suffer from several effects related to part placement. In this paper, the authors analyzed three primary error resources in grazing incidence interferometry: incidence angle error, rotation angle error and included angle. The mathematical foundations of these errors as well as measurement results of several samples are presented showing the effects of each of these errors on. Using the test procedures described in the paper, the errors can be greatly reduced and the repeatability and accuracy increased by 20%.


Idiopathic hemifacial atrophy also known as Parry-Romberg syndrome (PRS) is a rare neurocutaneous syndrome. It is characterized by slowly progressive atrophy of one side of the face, usually involving the skin, fat and connective tissue. A rare case of Parry-Romberg syndrome in a 30 year-old female is presented because of its rarity. The diagnosis of Parry-Romberg syndrome as established mainly based on the clinical findings. Not much is reported about the efficacy of agents used in the treatment of this syndrome in the literature making treatment decisions very difficult.


A new type of optically encoded, optically readable, high-density information storage has been demonstrated in commercially available silicate glass. The effect is based on optically encoded second-harmonic generation (SHG) in glass. Information is stored in the form of wavelength selective, one dimensional χ(2) gratings within the glass and is read out by illuminating the encoded area with light at designated wavelengths. During the encoding process, the glass evolves in time to produce SHG with efficiencies greater than seven orders of magnitude above the initial values. It has been shown that the SHG occurs via a frozen-in χ2, which oscillates as cos(Δkz), where z is the beam propagation direction and Δk = k(2ω) - 2k(ω) is the wavevector mismatch between the fundamental and second-harmonic beams. For a sample encoded with ωo, ωo/2), the SHG as a function of readout frequency, ω, varies as:


Historically, NYSE rule 452 permitted broker discretionary voting in routine voting matters such as election of directors. Since broker discretionary voting typically follows managements' recommendation, managements' nominees receive more votes than would otherwise be the case. Thus, any expression of true shareholder sentiment about directors is muted. Rule 452 was amended in 2009 to eliminate discretionary broker voting in the election of directors. We employ this regulatory event as a natural experiment to examine whether there is indeed any evidence of links between shareholder value and corporate boards. We find that the elimination of discretionary broker voting is value enhancing, on average. Importantly, the effect is more pronounced for firms with weak corporate governance, which suggests that effective boards of directors, if elected, can influence firm value.

This paper explains a technique that integrates conservative garbage collection on top of general memory allocators. This is possible by using two data structures named malloc-tables and jump-tables that are computed at garbage collection time to map pointers to beginning of objects and their sizes. This paper describes malloc-tables and jump-tables, an implementation of a malloc/jump-table based conservative garbage collector for Doug Lea's memory allocator, and experimental results that compare this implementation with Boehm-Demers-Weiser GC, a state-of-the-art conservative garbage collector.
