The sertolioma is one of the tumors that most affect older dogs, more incidents in criptorquidas animals. Usually these tumors are extremely expansive and can compress and destroy adjacent tissues. For their identification is necessary to carry out histopathological examination. This study aimed to report the occurrence of gonadopatia right criptorquidica, accompanied by neoplastic process associated in a dog of 10 years old. After orchiectomy the testes were sent to the Animal Pathology Laboratory of the Federal Rural University of Amazonia, and histopathological analysis the material was processed routinely for paraffin embedding and staining with hematoxylin -eosin (HE) and Masson's Gomory. Histologically, there was albugíneo by thickening of connective tissue proliferation. In the testicular parenchyma the tubules had only Sertoli cells were decreased in number and spaced proliferated dense connective tissue. The neoplastic process was located in a more central and, morphologically, it was observed in the tubular configuration, cell showing cytoplasmic vacuolization and some places featuring in palisades, characteristic morphological aspects of sertolioma.


The VIISta 810 medium current ion implanter beam line has been designed to produce beam currents from 2 /spl mu/A to 5 mA with energies from 2 keV to 810 keV. The beam is 200 mm or 300 mm wide on wafer, uniform to better than 0.5% (1/spl sigma/ RMS) and parallel to better than 0.7/spl deg/. The system uses a novel beam line architecture to address the stringent limitations on particle, metal, energy and cross contamination for sub 180 nm line width device requirements. The beam line architecture and optics are presented and performance data reviewed.


In this paper we consider the order-preserving submatrix (OPSM) problem. This problem is known to be NP-hard. Although in recent years some heuristic methods have been presented to find OPSMs, they lack the guarantee of optimality. We present exact solution approaches based on linear mixed 0--1 programming formulations and develop algorithmic enhancements to aid in solvability. Encouraging computational results are reported both for synthetic and real biological data. In addition, we discuss theoretical computational complexity issues related to finding fixed patterns in matrices.


Background: Hepatitis B virus infection is one of the serious public health problems in the world particularly in a developing country. It is transmitted from person to person by anybody fluid commonly through sexual intercourse. Hepatitis B virus infection has serious effects on both pregnant women and infants. Objective: This study aims to assess the magnitude of Hepatitis B virus infection and associated factors among pregnant women attending antenatal care service in Bishoftu town. Methods: A cross-sectional study was conducted involving a total of 276 pregnant women attending antenatal care service at Bishoftu town from July 17 - August 17, 2019. A systematic random sampling technique was used to select the study subjects. A blood sample was drawn from each study subject to testing for Hepatitis B surface antigen and confirmation for positive results was done by an enzyme-linked immune sorbent assay. Completed data from questionnaires were entered into Epi info version 7 and, exported and analyzed by SPSS Version 21. Descriptive statistics were carried out to estimate the characteristics of the participants. Bivariate and multivariate logistic regression analyses were used to identify factors associated with Hepatitis B virus infection. Odds ratios at 95% confidence interval were calculated. P-value < 0.05 was considered as a significant. Result: The magnitude of Hepatitis B virus infection among pregnant women attending antenatal care services in Bishoftu town was 18 (6.5%). Study subject with the previous history of the dental procedure [AOR=4.79, 95%CI (1.41 -16.23)], body tattooing [AOR=3.18, 95%CI (1.01-10.03)] and those with a multi-sexual partner [AOR=5.19, 95%CI (1.09-24.60)] were known to have a significant association with Hepatitis B virus infection. Conclusion and Recommendation: This study indicates that Bishoftu town has intermediate endemicity of Hepatitis B virus infection among pregnant women. Regarding the risk factors, pregnant women with a dental procedure, body tattooing, and multi-sexual partner were found to be at risk of Hepatitis B virus infection. To minimize the higher risk exposure status of mothers, increasing awareness and public health education on the mode of Hepatitis B virus transmission, high-risk behaviors and methods of prevention are recommended.

Summary The effect of shrinkage of the mortar on the strength of a concrete specimen is demonstrated by means of a lattice analogy for concrete. The strains due to the thermal incomptability of the cement paste and the aggregate in a concrete heated to high temperatures are taken as a particular example and it is shown that the results deduced from the lattice agree closely with those obtained experimentally by other workers. The limitations of the lattice approach are discussed: it is emphasized that the method is qualitative and that any extension to give quantitative results would be most unlikely to be successful.


The effect of extreme climate events on expansive soil roadbed water-destroyed was analyzed.The effect of maximum value of daily rainfall in different return periods and the different drought durations to expansive soil roadbed water-destroyed were calculated quantitatively.The analysis results show that the maximum value of daily rainfall and drought duration are the extreme climate events which affects the expansive soil roadbed water-destroyed.


Several numerical methods for the solution of a second-order damped system of the form MU(t) + 2CU(t) + KU(t) = F(t) are compared in this study. Factors considered in the comparison are stability, difficulty and cost of implementation, and accuracy. The methods we consider are Compact Implicit schemes, Central Differences, 'Hilson' s emethod, Fade approximations on equivalent first-order systems, and methods based on rational approximations to the cosine matrix. Both conditionally stable and unconditionally stable methods are studied. Problems with high frequency components in the solution are considered. The Pad� schemes are evidenced to be particularly effective.


Swift J1818.0−1607 is a radio-emitting magnetar that was discovered in X-ray outburst in March 2020. Starting four days after this outburst, we began a nearly five month multi-frequency observing campaign at 2.2, 8.4, and 32 GHz using telescopes in the NASA Deep Space Network. Using a dual-frequency observing mode, we were able to observe Swift J1818.0−1607 simultaneously at either 2.2 and 8.4 GHz or 8.4 and 32 GHz. Over the course of the campaign, we find that the flux density increases substantially and the spectrum changes from uncharacteristically steep (α < −2.2) to the essentially flat (α ≈ 0) spectrum typical of radio-emitting magnetars. In addition to the expected profile evolution on timescales of days to months, we find that Swift J1818.0−1607 also exhibits mode switching where the pulse profile changes between two distinct shapes on timescales of seconds to minutes. For two of the radio observations, we also had accompanying X-ray observations using the Neutron Star Interior Composition Explorer (NICER) telescope that occurred on the same day. We find a near anti-alignment (0.40 phase cycles) between the peaks of the radio and X-ray pulse profiles, which is most likely explained by an intrinsic misalignment between the X-ray and radio emitting regions.

BACKGROUND
Children with molar incisor hypomineralisation (MIH) frequently seek aesthetic treatment for incisor opacities. Surprisingly few studies have evaluated the clinical success of such interventions.

AIM
To quantify the effectiveness of minimally invasive treatments in reducing enamel opacity visibility in children with MIH.

DESIGN
This in-vitro study used digital clinical images of 23 children aged 8-16 years with MIH who underwent microabrasion and/or resin infiltration for management of incisor opacities. Standard images were taken pre- and six-months post-treatment. Image software (Image-Pro Plus®V7) was employed to convert 24-bit RGB images to 16-bit grey-scale and 45% magnification. Measurement repeatability was assessed using Intra-class Correlation Coefficients (ICC). Post-treatment changes in visible opacity area (mm2 ) and brightness (greyscale value) were tested using Wilcoxon Signed Rank Test for Related-Samples.

RESULTS
Mean total opacity surface area significantly reduced from 14.3mm2 (SD=7.5) to 9.4mm2 (SD=9.0) post-treatment. The proportion of tooth surface affected by the opacity also significantly reduced from 22.5% (SD=10.5) to 14.7% (SD=12.7). Mean maximum opacity brightness significantly reduced from 53066 greyscale value (SD=4740) to 49040 (SD=3796). ICC was good/excellent (0.75-1.0).

CONCLUSION
Minimally invasive treatment is effective in reducing size and brightness of discrete incisor opacities. Future research should compare objective findings with patient-reported outcomes.


A modified Ewald method is described for calculating the potential and its gradient for systems with long-ranged interactions and periodic boundary conditions (PBC). Following the work of Natoli and Ceperley, the division between the direct- and reciprocal-space terms is optimized by minimizing the squared deviation of the approximate representation from the exact form. In simulations using this method most of the computational effort is required in performing the reciprocal-space summation. For comparable accuracy, this method requires between one half and one third of the number of reciprocal-space lattice vectors of the standard Ewald technique. In addition our technique requires the choice of only a single parameter which controls the accuracy achieved, rather than the three parameters required in the standard Ewald technique. We give formulae (for the face-centered cubic (fcc), body-centered cubic (bcc) and simple cubic (sc) lattices), which allow for efficient evaluation of the terms in the reciprocal-space summation.


The present context of public concern for the implications of technological advance brings special pressures to bear on the scientist. He may be called on in an advisory capacity on the basis of his technical expertise; or he may himself feel that the nature of his work obliges him to take a position on public issues. Involvement of scientists in political activity has long been a sensitive and divisive issue within the scientific community, and scientists have traditionally approached political issues with reluctance. 'Politics has been considered an alien element, essentially destructive of scientific endeavour.'3


Things that need to be considered in studying eating habits are food consumption (quantity and quality), preferences for certain foods, beliefs, taboos, or attitudes towards certain foods. Lack of knowledge of pregnant women about nutrition affects the behavior of mothers in terms of food selection in fulfilling nutrition, thus causing a lack of nutritious food during pregnancy which can cause Chronic Energy Lack (CEL) in pregnancy. The Chronic Energy Lack (CEL) caused by lack insufficient energy and protein were to pregnant women. Chronic Energy Lack (CEL) for pregnant women were arm circumference above <23.5 cm and low birth weight babies (LBW) able to the potential to die, growth disorders and child development disordes. Also it was an indirect cause of maternal death. The purpose of this study was to determine the relationship between culture and knowledge with the incidence of Chronic Energy Lack (CEL) in first trimester pregnant women in coastal areas. The type of research is analytic observational with a cross sectional design to 49 respondents by purposive sampling, the subject is pregnant women who meet the inclusion and exclusion criteria by using a questionnaire. analysis using Chi-Square Test, from 49 respondents it is known that pregnant women who have good knowledge are 61.2%, pregnant women who have culture in the supportive category are 73,5% The results of the ChiSquare analysis test obtained a p value of 0.046 <0.05 which means that there is a significant relationship between the relationship between knowledge and Chronic Energy Lack (CEL) in Bunder Village, Pesisir District, Pademawu District, Pamekasan Regency.


When metallic materials become worn, a nanocrystallized layer is often observed under the worn surface. This layer is called the wear-induced layer (WIL). In this study, the mechanism behind the formation of the WIL by sliding wear under high stress for pure Cu is investigated. The microstructure around the worn surface changes discontinuously between the WIL and the plastically deformed region (PDR). The grain size in the WIL is much smaller than that in the PDR, whereas grains in the PDR underneath the WIL are refined by huge strain due to wear. From the results of crystallographic texture analysis, the WIL has recrystallization texture, whereas deformation texture with a 〈110〉 fiber is observed in the PDR. Hence, in the WIL, frictional heat causes recrystallization, which induces further grain refinement. It is concluded that the WIL is formed by both severe plastic deformation (SPD) due to wear and the recrystallization due to frictional heat.


Abstract We observed that the O2 delignification pattern of aspen kraft pulps was distinctly different from that of pine pulps based on a reduction in the apparent pulp kappa number. Much of this phenomenon can be attributed to the variation of the residual extractives and hexeneuronic acid (HexA) unit content in the unbleached and O2‐delignified pulps, as they interfered with the conventional lignin determination methods. However, after a correction for contributions from these non‐lignin components, the hardwood kraft pulps still displayed a lower response to O2 delignification than the pine pulps. It appears that the relative reactivity of residual lignin in the hardwood and softwood pulps differs appreciably with the extent of kraft delignification, and is a significant factor affecting the overall O2 delignification reaction.


Midday meal programs at schools are prevalent in countries such as India. The Akshaya Patra Foundation, a not-for-profit organization, operates such a program in India for about 1.3 million children in more than 9,000 schools in nine states. The foundation faced a logistics problem in efficiently distributing food within the available time window. This paper discusses the challenges it faced, how we used OR modeling to overcome them, and how we designed, developed, and implemented a software solution. To address the logistics problem, we proposed a three-stage decomposition heuristic solution, which consists of clustering schools, assigning appropriate distribution vehicles to clusters, and routing vehicles within the clusters. We implemented our solution, AMRUTA, on a pilot basis in one location. Based on this pilot, the projected annual cost savings are US$75,000, which would enable the foundation to add 2,400 more children. When the program is fully implemented, we estimate that the annual cost savings will be about US$1.96 million. This project demonstrates how operations research can be useful for solving social sector problems in a developing country such as India.

TCP performance over wireless network has been extensively studied in the literature and many cross-layer optimization schemes are proposed. Nevertheless, new technologies such as WiMAX, based on IEEE 802.16, offer new dimensions for system optimization that limited research has explored. In this paper, we show that the flexible WiMAX MAC layer allows cross-layer optimization to be done at the fine granularity of each connection or each service class. We also highlight that in a WiMAX broadband wireless access network, aggregate system performance is more important than the performance of an individual application instance, particularly from a network operator point of view. To this end, we propose an asymmetric link adaptation strategy for TCP-based applications. Coupled with ARQ, the aggregate system performance is enhanced without significantly compromising the performance of individual TCP flow. In addition, we argue that schedulers should be designed specifically for different service classes. We propose a scheduler for TCP-based best-effort service class that achieves both good aggregate throughput and fairness. The proposed design concepts not only help to achieve a good end-to-end TCP performance along with enhanced spectral efficiency, but also open many possibilities for optimizing the performance of other applications with similar techniques in WiMAX


A brake temperature detection device: acquires a kinetic-energy based temperature rise, which is an increase in an amount of brake heat that occurs when kinetic energy generated in a running vehicle is converted into thermal energy by braking; acquires a braking-energy based temperature rise, which is an increase in an amount of brake heat that is calculated from an amount of work done when a brake's friction material is pressed against a friction target material; determines state of slope of a road surface on which the vehicle is running; and detects a brake temperature in accordance with an increase in an amount of brake heat generated in braking. The brake temperature detection device selects, based on the state of slope, either the kinetic-energy based temperature rise or the braking-energy based temperature rise as the increase in the amount of brake heat generated in braking and achieves brake temperature detection.


Abstract An enduring paradox of China's remarkable economic growth is the lack of a well-established legal system. By drawing on the credibility thesis, this paper proposes that legal and economic reforms give rise to, and reinforce, the other and the market is underpinned by evolving institutions that are shaped by the expectations of the actors in the economy. It is thus not the form of institutions but their function that is more important in assessing institutional performance. A comparative examination of the USA at a similar stage of legal-institutional development to China provides support for an evolutionary, endogenous process. This institutional analysis will focus on key issues of economic legislation, such as corporate law, patent law and securities. Analyzing the relationship as complementary processes can help explain the paradox of strong economic growth within an under-developed system of law with potential, critical implications for institutional development in other countries.


Abstract In order to improve our understanding of the glass transition we performed constant-energy molecular dynamics simulations on a soft-sphere system quenched from the liquid state to zero temperature. The temperature dependence of static (radial pair distribution function) and dynamic quantities (self-diffusion constant) has been investigated together with the temperature evolution of relevant structural properties deduced from the Delaunay-Voronoi tessellation of these samples. This study permits to shed new light on the structural freezing below the glass transition temperature and the evolution of the local structure through the transition.

In spite of the incredible advances in computing, battlefield information distribution and processing remains archaic because of the common pitfall of simply automating manual techniques. New technologies have been developed to thwart the propagation of this practice and provide automated information distribution between computers using the limited and constantly varying bandwidth of standard combat net radios. The new technologies are based on three major tenets, namely, exchange data (1) in its most general form, (2) only when truly necessary, and (3) in an efficient manner.<<ETX>>


The article argues the conclusion about the need to reform the education system in the field of economic theory. The reason for this is both the general problems known for many decades of reducing this field of teaching to courses in micro- and macroeconomics with some additions, and new circumstances — profound changes in economic life in the world in general and in Russia in particular. The authors show that the beginning of qualitative changes in technology, the aggravation of global problems and geopolitical confrontations necessitated transformations in the space of economic relations and institutions. The still dominant model of late capitalism is in crisis, which is recognized not only by critics, but also by adherents of this system (in particular, the leaders of the Davos Forum). In the Russian Federation, the changes in economic life are even more profound. In these conditions, fundamental economic education is necessary, which adequately reflects the changes taking place, preparing entrepreneurs, civil servants, households to make decisions in new conditions. Based on neoclassical postulates, micro- and macroeconomic theory, even if supplemented by developments in behavioral economics and new institutionalism, cannot fully reflect new phenomena. Meanwhile, at present, the teaching of economic theory is reduced to these courses, although there are important exceptions (courses, textbooks in China, Russia, the USA, Europe) that show the fruitfulness of a different model of teaching economic theory, which includes not only neoclassics. The article concludes with a system of concrete proposals for the restructuring of the education system in the field of economic theory in Russia.


Steeped in scholarship and exuding an air of dreamy tranquility Cambridge was an ideal setting for the recent BMA scientific meeting, which was held in Churchill College. Medical education was the theme of the opening address, which was delivered by Professor Sir John Butterfield, regius professor of physic at Cambridge University. Gone are the days, he said, when students can expect to leave medical school armed with enough knowledge to carry them through their professional lives. Postgraduate education was essential for all doctors and it was a process which should continue throughout their careers. He went on to say that senior staff should take more responsibility for guiding students and newly qualified doctors into those professional niches which were most suitable for them. On the controversial question of student numbers he suggested that medical schools should maintain their cuirent intake, but requirements for the future must take into account the working pattern of women in medicine. The programme covered a broad range of medical topics but continued the theme of medical education by bringing the audience up to date on recent developments in several specialties. The sessions offered a catholic choice-from in vitro fertilisation through day care surgery to lasers-but they succeeded in kindling much interest and enthusiasm, which were reflected in the lively discussions. While few doubted that Professor Butterfield's reference to the Hippocratic aphorism "life is short, but the art is long, the opportunities fleeting, the problems perilous, the judgments difficult" was apposite, spring was in the air and this meeting engendered a welcome spirit of optimism.


The authors describe an extremely high performance Si bipolar preamplifier, which has a 15.5-GHz bandwidth with a transimpedance gain of 52 dB Omega . To achieve such high performance, the optimization of feedback parameters in the circuit and the realization of the 46-GHz f/sub max/ (maximum frequency of oscillation) transistor were carried out simultaneously. The circuit consists of gain and buffer stages. Employing a dual-feedback configuration in the gain stage design, the preamplifier has broadband and low-noise characteristics. The measured frequency response of the preamplifier, using the optimized circuit and the improved transistors, is shown.<<ETX>>


Wilbur Smith Associates has developed a GIS based analysis tool in ArcGIS that can provide easy user access to the Georgia Department of Transportation(GDOT) Road Characteristics and other related traffic information. The tool can query and visually display the information at a county wide or road/segment level. The tool also has the option to generate a geographic information system (GIS) based straight-line-diagram (SLD). The strength of the SLD is that it presents information in a 1-D format that is easy to understand as compared to 2-D and 3-D formats that can be difficult to understand. The information is critical for providing the foundation for making sound decisions and setting policy and important to evaluating the critical issues facing the State of Georgia.


Granite is an igneous rock which is widely used as construction material in different forms. Granite industries produce lot of dust and waste materials. The wastes from the granite polishing units are being disposed to environment which cause health hazard. This granite powder waste can be utilized for the preparation of concrete as partial replacement of sand. In order to explore the possibility of utilizing the granite powder as partial replacement to sand, an experimental investigation has been carried out. The percentages of granite powder added by weight to replace sand by weight were (0%, 5%, 10%, 15%, 20% and 25%) and various tests such as compressive strength, Split tensile strength and Flexural strength are investigated and these values are compared with the conventional concrete without granite fines. Standard cube of 150X150X150mm will be cast and tested for obtaining 28-day compressive strength. Standard cylinder of 150mm diameter and 300mm height will be cast and tested for split tensile strength. Standard beam of 500X100X100 will be cast and tested for flexural strength. Then analyze all the result mathematically and graphically.


A new naphthalene, 8-methoxy-2,7-dihydroxyl-4-(1'-hydroxyl-isopropyl)-6-methyl-1-naphthaldehyde, together with twelve known compounds were isolated from the tubers of Kosteletzkya virginica. Their structures were elucidated by spectroscopic methods, including 1D-, 2D-nuclear magnetic resonance (NMR) and high-resolution time of flight electrospray ionization mass spectrometry (HRTOFESIMS). Some compounds were evaluated for their potential in scavenging diphenyl-picryl hydrazyl radical (DPPH•), inhibition of nitric oxide (NO) induced by lipopolysaccharide (LPS), and cytotoxic activity. The new compound showed activities against DPPH•, NO, human acute promyelocytic leukemia (HL-60) and human colorectal adenocarcinoma (LOVO), with IC50 of 34.6, 12.5, 40.5, 31.7 μmol L-1 respectively.


Soil and water conservation measures including terracing, afforestation, construction of sediment‐trapping dams, and the 'Grain for Green Program' have been extensively implemented in the Yanhe River watershed, of the Loess Plateau, China, over the last six decades, and have resulted in large‐scale land use and land cover changes. This study examined the trends and shifts in streamflow regime over the period of 1953–2010 and relates them to changes in land use and soil and water conservation and to the climatic factors of precipitation and air temperature. The non‐parametric Mann–Kendall test and the Pettitt test were used to identify trends and shifts in streamflow and base flow. A method based on precipitation and potential evaporation was used to evaluate the impacts of climate variability and changes in non‐climate factors changes on annual streamflow. A significant decrease (p = 0.01) in annual streamflow was observed related to a significant change point in 1996, mostly because of significant decreases in streamflow (p = 0.01) in the July to September periods in subsequent years. The annual base flow showed no significant trend from 1953 to 2010 and no change point year, mostly because there were no significant seasonal trends, except for significant decreases (p = 0.05) in the July to September periods. There was no significant trend for precipitation over the studied time period, and no change point was detected. The air temperature showed a significant increasing trend (p < 0.01), and 1986 (p < 0.01) was the change point year. The climate variability, as measured by precipitation and temperature, and non‐climate factors including land use changes and soil and water conservation were estimated to have contributed almost equally to the reduction in annual streamflow. Soil and water conservation practices, including biological measures (e.g. revegetation, planting trees and grass) and engineering measures (such as fish‐scale pits, horizontal trenches, and sediment‐trapping dams) play an important role in reduction of the conversion of rainfall to run‐off.

The aim of this work is to employ the artificial neural networks for modelling the magnetic properties of the amorphous alloys with the iron and cobalt matrix. The artificial neural networks implemented in StatSoft Statistica Neural Network PL 4.0F were used to determine the relationship between the chemical compositions of amorphous alloys, heat treatment parameters and magnetic properties. The attempt to use the artificial neural networks for predicting the effect of the chemical composition and heat treatment parameters on the magnetic flux density BS succeeded, as the level of the obtained results was acceptable, as the level of the obtained results was acceptable. For different magnetic properties of soft magnetic materials, further calculations are planned. The results of calculation makes it possible to design new advantageous combinations of concentrations of the particular elements to develop grades of the soft magnetic alloys. This paper employs the artificial neural networks for modelling chemical composition and heat treatment parameters of amorphous soft magnetic alloys to obtain the best magnetic properties.

who more than anybody else need protection from others and not vice versa. Those who are kept in prison-like conditions only for travelling undocumented or for being unwanted, like the Roma in France, are indeed likely to be subjects of abuse and deprivation of all basic human rights again, as the examples of immigration detention prove. Laura Zahra McDonald, through an extensive ethnographic investigation, instead, highlights the consequences of Islamophobia in the UK, where integration seems to conflate with a concept of assimilation that is disrespectful of individuals' freedoms and cultures. A discussion of the term "integration" would probably even strengthen her argument that points at criticizing this conceptual framework. Through her narratives, integration, as it is currently conceived in the UK, seems to leave only on "the Others" – the British Muslims – the burden and responsibility of the quality of social relationships in the country. The UK is also in the spotlight for the following case study, which concerns British-Somalis as subjects of particular surveillance due to their "visible" presence, being a community mostly composedof black, youngmales ofMuslim faith. The qualitative methodology of analysis permeates the rest of the book as well, first in the interesting description that Emanuele Toscano presents of the rise of Italian populism and then in the works that Lazaridis first coauthors with Konsta in a chapter on the different fashions of identitarian populisms in Greece and the UK and second writes together with Tsagkroni on the case study of the Scandinavian countries. This book overall represents a careful plot gathering both in-depth qualitative investigations of specific case studies and thorough analyses of a variety of practices involved in the process of securitization of migration. Therefore, it is timely in dealing with the topic. In particular, it illustrates, through different angles and with interdisciplinary lenses, how the most evident security issue that is connected to migration is the insecurity that migrants and minority communities experience in both their every day life and exceptional situations. In its well-structured wide range of issues debated, what is missing, perhaps, are some positive examples of how, instead, migration can be a channel through which diversity contributes to creating more inclusive and less populist societies, where the others are not socially constructed as security threats. There are plenty of examples across Europe of civil societies expressing solidarity to those who are forced to migrate, which also deserve to be studied as forms of counter-movements of the securitization of migration. And yet, all scholars and experts interested in the nexus between migration and security should read this compelling volume, as it shows the interconnectivity of three diverse components of the securitization of migration in terms of practices, consequences and outcomes, whose understanding is fundamental to help resolve insecurities in the European continent in this field.


OBJECTIVES
To analyze the survival rate of nasopharyngeal carcinoma (NPC) and to evaluate the effect of intervention in this high risk population of NPC.

METHODS
Based on the cancer and vital registry systems, the follow-up data of 1761 NPC cases were collected. The measures of survival include 5-year, 10-year survival rate and median survival duration. Cox model was used to screen the independent prognosis factors.

RESULTS
The 5-year and 10-year survival rates of NPC cases in Sihui were 50.62% and 37.01%, and the median survival duration was 5.05 years. The survival rate of NPC cases diagnosed after 1993 was 58.8%, which was higher than that of cases diagnosed before 1993 (43.3%). Other prognosis factors included gender, age, clinical stage and diagnostic hospital.

CONCLUSION
There is a significant improvement of NPC survival in Sihui. That is mainly related to the improvement of NPC treatment. However, it needs to a long time observation to see a mortality reduction of NPC.


Monthly means of UV erythemal dose at ground level from the Robertson-Berger (RB) sunburn meter (1976-1992) and the UV-Biometer model 501 MED meter (1993-1994) located at Belsk (21°E, 52°N), Poland, are examined. The monthly means are calculated from all-sky daily means of UV erythemal dose. Ancillary measurements of column ozone (by Dobson spectrophotometer), sunshine duration (by Campbell-Stokes heliograph), and total (sun and sky) radiation (by a pyranometer) are considered to explain variations in the UV data. A multiple regression model is proposed to study trends in the UV data. The model accounts for the UV erythemal dose changes induced by total ozone, sunshine duration (surrogate for cloud cover variations), or total solar radiation (surrogate for combined cloud cover and atmospheric turbidity impact on the UV radiation), trends due to instrument drift, step changes in the data, and serial correlations. A strong relationship between monthly all-sky UV erythemal dose changes and total ozone (and total solar radiation) is found. Calculations show that an erythemal radiative amplification factor (RAF) due to ozone under all skies is close to its clear-sky value (about 1). However, the model gives evidence that the RAF due to ozone is smaller for cloudier (and/or more turbid) atmospheres than long-term reference. Total solar radiation change of 1% is associated with a change of 0.7% in the UV erythemal dose. Modeled trends in the Belsk's UV data, inferred from the model using ozone and total solar radiation as the UV forcing factors, are 2.3% ± 0.4% (1σ) per decade in the period 1976-1994. The large increase in the UV erythemal dose, of the order of 4% per decade due to ozone depletion (-3.2% per decade), is partially compensated by a decreasing tendency (-2.8% per decade) in total solar radiation. The model estimates the trend in the UV data of the order of 0.1% per decade (not statistically significant) due to superposition of the instrument drift and long-term effects related to other UV influencing factors (not parameterized by the model).

In surgical training, it is very important to maintain the balance between providing training to young surgeons and maintaining surgical quality. In this study, we investigated the safety and efficacy of laparoscopic cholecystectomy (LC) performed by an attending doctor along with young surgeons. The patient background and intraoperative and postoperative factors were compared between 2 groups : the R group, in which LC was performed by an attending doctor and 2 young surgeons, and the S group, in which LC was performed by the same attending doctor with 1 young surgeon and an-other attending doctor. The operation time in the R group was longer than that in the S group, espe-cially in normal cases without cholecystitis. However, no significant intergroup differences were found in preoperative patient characteristics, intraoperative blood loss, and postoperative outcomes. Young surgeons can actively participate in LC, and it is more feasible for them to assist the attending doctor during the procedure.


ABSTRACT This review summarises the biology and ecology of the distinctive North Island New Zealand endemic tree Ixerba brexioides (A.Cunn.). The genus Ixerba is monotypic and belongs to the family Strasburgeriaceae found only in New Zealand and New Caledonia. Ixerba brexioides (tāwari) is a New Zealand tree restricted to rain forests north of 39°S latitude in areas of mature soil in mild, moist climates. With conspicuous white flowers displayed en masse between November and January each year and dark green, long and toothed leaves arranged in whorls, it has earned recognition as one of New Zealand's most attractive trees. Inflorescences are predominantly insect pollinated, with occasional bird visitation. Capsular fruit are produced in early autumn and dehisce to reveal dark black-purple seeds with an orange fleshy aril that are bird dispersed. Seeds germinate quickly, without a dormancy period, most commonly on soil, logs and mounds, but grow slowly (1.6–2.4 mm year diameter growth rate) in shade conditions until canopy gaps open. Chemicals associated with its leaves include ursolic acid and proanthocyanidins, but their significance is unknown. Agglomerative hierarchical cluster analysis defined four main forest types dominated by I. brexioides centred on Northland, Waikato, Coromandel and Urewera, the floristically richest occurring in Northland. The genus first appeared in the fossil record in New Zealand in the late Eocene. Flowers of I. brexioides (whākou) were historically used by Māori in garlands and necklaces, while peak flowering was a signal to harvest certain crops. Ixerba brexioides honey is popular and honey crops are sought after in areas where the trees are abundant and accessible to beekeepers. Though not currently threatened, the distinctive and geographically limited I. brexioides is one of the many New Zealand trees requiring additional research. Priorities include potential threats of climate change, susceptibility to inbreeding depression and the role of birds as dispersers.


A communication system is disclosed comprising a first base station operating a first cell and a second base station operating a second cell. The first base station determines that load should be offloaded from the first cell towards the second cell based on a comparison of respective measurement result of a first type obtained for the first and second cells. The first base station controls load balancing based on a second comparison of respective measurement result of a second type for each of the first and second cells, wherein a second condition, when met, indicates that the base station operating the second cell will not offload load to the first cell based on the respective measurement result of the second type for the first and second cells.

The invention discloses a color separation method of a spectrum of a printing system with multicolor printing. The color separation method comprises the following steps of splitting sub-models of the printing system with multicolor printing, and judging whether a spectrum for color separation is arranged in a color gamut of one sub-model one by one so as to form a sample set P; further splitting each sub-model in P to a plurality of super cells and mini cells, wherein the super cells are formed by a certain number of mini cells; judging whether the spectrum for color separation is arranged in one super type one by one so as to form a sample set C; taking an error of the spectrum as evaluation measurement, selecting P optimal cellule from all mini cells included in the super cells from C, carrying out color separation on the spectrum in each mini cell by taking phi as evaluation measurement, and taking a color separation ink quantity value with optimal phi precision as a final color separation ink quantity value so as to complete color separation. According to the color separation method, the color separation precision of the printing system with multicolor printing is guaranteed, the color separation efficiency and the measurement switchover flexibility are remarkably improved, and the color separation method is convenient for implementation and has higher applicability in the field of high-fidelity color copy.


1.IntroductionMost researchers believe that engaged readers approach reading with eagerness (see Pintrich & DeGroot, 1990; Schiefele & Rheinberg, 1997). Pursuing clear reading goals, readers focus their attention purposefully and demonstrate well-established habits of concentration. They take pleasure in using their skills to understand a text and invest special effort in what they care about most (Meyer and Rose, 2002). Students become deeply engaged in reading for many reasons: the subject or the author's handling of words fascinates them; they are challenged to just the right degree and feel themselves progressing and learning; they enjoy doing what they do well; or working hard at reading serves a broader goal of doing well in school (Chall & Onofrey, 2002).Engagement is essential to successful reading. Based on Meyer and Rose (2002), the students who are beginning to read must be engaged in the material they are trying to read and in the process of learning. Excellent readers learning advanced comprehension skills read more effectively if they are interested and confident of their ability to succeed. Every teacher knows that engaging students in reading includes building their confidence and arousing their interest, and desire. Successful teachers help students think of themselves as readers. How do we conclude if a reader is engaged or unengaged? Sabine & Sabine (1983, p. 29 as cited in M.O. Tunnell & J.S. Jacobs, 2009) argued that an engaged reader is not aware of the reading process, s/he even doesn't even see words after the first sentence or two. They are unaware of how many pages they have read or how long they have been reading. When engaged readers come to a word they can't pronounce or define, they skip right over it without hesitation. A real reader engaged in a book is not cognizant of reading skills (M.O. Tunnell & J.S. Jacobs, 2009).Some research indicate that the emotional competencies which affect reading include: stress management (stress tolerance and impulse control), adaptability (problem solving, reality testing, and flexibility), and general mood(happiness and optimism). To be a good reader, one must know how to cope with and manage stressful situations, how to define problems and generate potentially effective solutions, how to evaluate the correspondence between objective and subjective reality in a realistic and well-grounded fashion, and how to adjust emotions, thoughts, and behaviors to changing conditions. Being satisfied with life, enjoying being with others, and maintaining a positive attitude even in face of adversity is true requirements of successful reading.1.2.Rationale for the StudyA great deal of research on reading in particular has focused on the cognitive aspects of reading (see for example Adams, 1990; Mosenthal, & Pearson, 1991; Ruddell, & Singer, 1994, as cited in Robert Rueda, Laurie MacGillivray and Lilia Monzo, 2001). However, Robert Rueda, Laurie MacGillivray and Lilia Monzo (2001) argued that many researchers and theoreticians have begun to reconsider the balance between cognitive and affective (specifically motivational) aspects of reading (Guthrie & Wigfield, 2000; McCombs, 1989 as cited in Robert Rueda, Laurie MacGillivray and Lilia Monzo, 2001).No doubt that engaged reading is an affective procedure through which the reader is engaged in the process of reading. Engagement depends upon a complex mixture of intrinsic and extrinsic factors. Also, based on what Kathleen C. Perencevich (2004) mentioned, as students perceived their instruction to be motivating, their reading engagement would increase. Autonomy support and conceptual press are considered as the major components of reading engagement (Kathleen C. Perencevich, 2004). Reading engagement also includes cognitive, motivational and behavioral characteristics. The main purpose of the current, therefore, is to investigate the relationship between the engaged reading and emotional intelligence. …

The gross morphological development of the central nervous system of vertebrates has engaged the attention of investigators for many years with the result that our knowledge of the subject is now relatively complete. In contradistinction to this, the study of development of intrinsic structures in the nervous system has lagged behind. It is true that many isolated facts of intrinsic growth have appeared from time to time, especially in regard to late fetuses in which the organization of principal centers of activity had begun earlier. Much attention has been given to the myelinization of fiber tracts although their early fibrillization is quite obscure. Knowledge of phylogenetic development of the nervous system has advanced beyond that of ontogenetic. Our incomplete knowledge of intrinsic neuron formation can be attributed to failure to use suitable technical methods. Few attempts have been made to study early fiber-tract


The purpose of our article and its conclusions were not to "excuse" physicians from providing education and services to adolescents about sexuality and pregnancy. The purpose of our study was to educate physicians about the current effectiveness of school-based programs and to stimulate further involvement of the medical community in designing, implementing, and evaluating new, innovative, and potentially more effective approaches. We agree with Ms Senderowitz that a multifactorial approach is needed and that school-based programs are but one component of a broader effort.


In retranslating classics,the translator should aim at surpassing his predecessors.Sun Zhili borrowed reasonably from Zhang Guruo,but on the other hand,his understanding of the original is deeper than Zhang's and in the course of translation,he put into practice a new concept of translation.Therefore,Sun's version is different from Zhang's in many aspects.On the whole,Sun's version has surpassed Zhang's and can be justifiably considered a successful retranslation.


This paper presents the identification, development and simulation of a complex order, third generation CRONE controller for a new vertical-axis wind turbine prototype of the Darrieus type. The prototype was tested in a wind tunnel and the data used to develop an accurate model, validated experimentally. The CRONE control system design methodology was then used to develop a robust controller, which was then tested in simulation. Simulations allow for parameter uncertainty and different wind conditions, with and without the presence of turbulence. This control system can be easily implemented using an Arduino platform.


a questionnaire survey of 41 Liberal Studies (LS) teachers from 40 secondary schools and interviews with 12 of them, the researcher compared the teaching processes and strategies for nurturing students' higher-order thinking (HOT). The study seeks to find out whether the LS implementation process is aligning with the aims of the curriculum. Result show that teachers have a strong tendency towards examination-oriented learning while acknowledging the focus on knowledge-based learning as the main difference of LS and its public assessment component from those of the traditional disciplines, the emphasis of the subject on the mastery of basic concepts and thinking skills and the need for the nurturing of HOT. There was widespread agreement with the operation of the public assessment design in the subject. The more experienced ones further agree that examination-oriented strategies are compatible with the development of HOT.


We present a real time multistage interactive track algorithm for wide field of view staring infrared system. Algorithm contains three main stages: a simple track according correlation, a fine track base on content and a screener served for both. If track mission is easy, the first simple track runs. If it couldn't track effectively, the second fine track will take over. Screener judges which track stage run, saves all possible targets and information for more track. Algorithm adjusts operational flexibility according different track situation. Finally, algorithm was demonstrated via simulation of real infrared image sequences. Results show that the performance of the fine track is better than the simple track. This interactive algorithm can work effectively and be robust for more widely using.


ABSTRACT Since the mid-1990s, major cities in China have generated a boom in the production of urban spectacles. But existing literature cannot fully explain why these cities are willing and able to participate in these events. This paper documents this boom and argues that the enthusiasm for producing urban spectacles is driven by a strong developmental imperative and sustained by the soft budget constraints of the spectacle organizers – urban governments. These two factors are embedded in the transitional institutional environment of China in relation to power decentralization, central-local fiscal rearrangement and the top-down systems of official evaluation. Embedded in in such a political-economic environment, urban governments generally become ambitious and adventurous in launching pro-growth urban projects. Urban spectacles become one of the pretexts for achieving extraordinary development. This paper reveals this hidden political economy through the case of the 2010 Asian Games in Guangzhou.


A layer of a non‐Newtonian liquid, of which the constitutive equation is triply nonlinear, flows down an inclined plane under the action of gravity. The stability of the flow against wave formation is investigated. With M denoting a parameter involving the first and the second viscosities, the critical Reynolds number is given as a function of M and the slope of the plane, for small values of M. The theory presented here shows how free‐surface instability of non‐Newtonian fluids can be attacked, and provides a basis for stability experiments with non‐Newtonian fluids.


Atom transfer radical polymerization using activators generated by electron transfer (AGET ATRP) of acrylonitrile (AN) initiated by ethyl 2-bromoisobutyrate (EBiB) was approached for the first time in the absence of oxygen and in the presence of air, using a novel catalyst system based on SmBr3·6H2O/isophthalic acid complexes and using ascorbic acid (VC) as a reducing agent. Both the polymerization in the absence of oxygen and in the presence of air proceeded in a well-controlled manner as evidenced by kinetic studies. Compared with the polymerization in the absence of oxygen, the polymerization in the presence of air provided rather slow reaction rate and showed better control of molecular weight and its distribution under the same experimental conditions. The polymerization apparent activation energies in the absence of oxygen and in the presence of air were calculated to be 47.1 and 51.3 kJ·mol−1, respectively. A slow polymerization rate and a broad polydispersity index were observed using anisole and toluene instead of DMF as solvent. Polyacrylonitrile obtained was successfully used as a macroinitiator to proceed the chain extension polymerization of styrene via AGET ATRP in the presence of air.


This study was was carried out from 1963 to 1965 to find out which insects were currently or potentially important to North Dakota shelterbelts, and to determine if their distribution and abundance were influenced by climate and host age.


New records of parasitic hymenopterans are presented from Arkansas including 50 new state records and 14 significant range extensions into the state. Twenty-three parasitic wasp species were discovered in nine seeps/springs in the Ouachita National Forest while 21 parasitic species were found in eight springs in the Ozark National Forest. The findings from these Arkansas seeps and springs based on pan-trapping demonstrate the importance of these unique habitats.


The present work is on the stability of forced convection in a tightly coiled square duct of curvature ratio 0.5 in high Dean number region. Dynamic responses of multiple flows to finite random disturbances are examined by direct transient computation. It is found that physical realizable, fully developed flows evolve to chaotic oscillations at high values of Dean number. The power spectrum of these oscillating flows is constructed by empirical mode decomposition and Hilbert spectral analysis for the characteristics of chaotic oscillations. With increase of the Dean number, the temporal scale of chaotic oscillation becomes wider; high-frequency flows appear, and the energy contained in the bursts becomes stronger.


Airfoil buffet boundary is an important aerodynamic parameter which is second only to the liftdrag ratio.By using various steady aerodynamics parameters of the reversal in shock wave as the basic criteria,the buffet boundary of transonic airfoil RAE2822 in transonic flow conditions can be determined by solving steady Reynolds-averaged Navier-Stokes equation.Using the same method to find the buffet boundary of RAE2822 with Mini-TED and comparing it with the buffet boundary of the basic RAE2822 airfoil, the results show that the Mini-TED can significantly increase the lift coefficient near the buffet onset angle,stabilize the buffet onset angle,thereby achieving the purpose of expanding the buffet boundary. The buffet onset lift coefficient in this case can be increased by 9%~13%.

force is a natural force in many biological systems. It impinges on molecules, cells and tissues as well as on whole organisms. Such functional units respond differen-tially to sensitivity and natural environment biological function shape their Abstract Very few publications exist that address the influence of liquid handling induced shear stress on the integrity of functional units like cells, DNA, and proteins. In this study we examined the shear stress of different liquid handling systems in theory through computer simulation and in practice through laboratory experiments. Building an example under extreme conditions, we were, indeed, able to show that functional units experience shear stress through liquid handling. This shear stress stimulus has a very short duration as this occurs on the tip's orifice. In our cell culture test system, we determined that the number of pipetting steps was the most important influencing factor because with only one pipetting the shear stress effects on cell death and proliferation, even at maximum piston speed, were negligible for HEK 293 cells. With iPSCs we were able to define a more differentiated picture underlining the fact that the instrument and the tip constitute a system. It is neither the tip's orifice nor the instrument's piston speed alone that influences shear stress, but rather the system comprising both that influences flow velocity. We strongly recommend using electronic devices when pipetting functional units because they achieve a low flow velocity. This delivers results independent of the user, thus improving reproducibility.


We have investigated the charge-discharge mechanism in the first cycle and the origin of its high charge―discharge capacity for Li 1.2 Mn 0.4 Fe 0.4 O 2 (0.5Li 2 MnO 3 ·0.5LiFeO 2 ) positive electrode material of lithium ion batteries. Results reveal that oxygen loss occurs in the entire region of the Li 1.2 Mn 0.4 Fe 0.4 O 2 particles composed of Mn-rich (Fe-substituted Li 2 MnO 3 ) and Fe-rich (Mn-substituted LiFeO 2 ) nanodomains during the first charge. Nanodomains of Mn-Li ferrites with a spinel structure start to be formed along the particle surfaces. During the first discharge, the extracted oxygen is partially reinserted preferentially into the Fe-rich nanodomains as oxide ions rather than in the Mn-rich nanodomains, and the proportion of the spinel nanodomains decreases. The origin of the high charge―discharge capacity might be ascribed to the participation of the oxide ions and neutral oxygen species in charge compensation by incorporation of the LiFeO 2 component into Li 2 MnO 3 . Irreversible capacity at the first cycle can be caused by the irreversible loss of oxygen during the charge and irreversible structural changes throughout the cycle: the movements of transition metal ions inducing random cation-site occupation throughout the cycle, associated with the formation and incomplete disappearance of the spinel ferrite nanodomains which is almost electrochemically-inactive under the applied voltage range.

The koala, Phascolarctos cinereus, is an iconic Australian wildlife species, but faces rapid decline in South-East Queensland (SEQLD). For conservation planning, estimating koala populations is crucial. Systematic surveys are the most common approach to estimate koala populations, but such surveys are restricted to small geographic areas, they are costly and conducted infrequently. Public interest and participation in the collection of koala sightings is increasing in popularity, but such data is generally not used for population estimation. We used incidental sightings of koalas reported by members of the public from 1997-2013 in SEQLD to estimate the yearly spatio-temporal koala sightings density. For this, a spatio-temporal point process model was developed accounting for observed koala density, spatio-temporal detection bias and clustering. The density of koalas varied throughout the study period due to the heterogeneous nature of koala habitat in SEQLD, with density estimates ranging between 0.005 to 8.9 koalas per km2. The percentage of land areas with very low sightings densities (0-0.25 koalas per km2) remained similar throughout the study period representing in average (SD) 68.3% (0.06) of the total study area. However, land areas with more koalas per km2 showed larger annual variations, with koala mean (SD) densities of 0.25-0.5, 0.5-1, 1-2, 2-5 and > 5 koalas per km2 representing 16.8% (0.21), 13.8% (0.25), 0.7% (0.20), 0.3% (0.13), and 0.2% (0.1) of the study area in South-East Queensland, respectively.We did find that clustering of koala sightings was not prominently different between the mating and non-mating seasons of koalas. While acknowledging the limitations associated sightings data, we developed a statistical model that addressed the spatio-temporal bias associated with observed koala sightings and provided long-term relative koala density estimates for one of the largest koala populations of Australia.


Most image processing systems contain a set of predeened data structures which represent images, edges, regions etc. However, there is usually little support for user-deened data types or for extensions of existing types. Furthermore, it is often diicult to store customized data structures in les, or to send them between diierent processes. In this article, an object-oriented communication scheme based on persistent objects is presented. It will be demonstrated how such a mechanism can be incorporated into several existing image processing systems and what the advantages of the approach are. In this context, some general principles of object-oriented design and how they can be applied to so called computational networks will also be discussed.


At the beginning of the 20th century life expectancy in the western world was 47 years, and by the end of the century it had reached 76 years. Although there was an increase in life expectancy of only 22 years over a 1,000 year period from the beginning of the 10th century to the 20th, in the relatively short time between the 20th and 21st century life expectancy increased by 29 years. Thus, we are entering the 21st century with an aging population and a forecast that within another 50 years 20% of the world's population will be elderly. By the year 2020 every fourth person in Japan and Sweden will be at least 65 years old, with a substantial number of people over the age of 80 as well. It is predicted that by 2035, in countries such as Spain and Italy, people aged 65 and over will comprise more than 35% of the population. Among countries in the western world with aging populations, Israel is considered to be a relatively young country. A 20 year forecast indicates that the number of people aged 65 will not significantly increase, but this forecast is misleading in that there will be a significant increase in the population of people aged 75 and over. For some reason Geriatric Medicine has not become as respected a field for specialization as others, and changing this direction is an important mission for the leaders of geriatric medicine in Israel. Just as the difference between pediatric medicine and adult medicine has gained recognition, so must geriatric physicians promote the recognition that there is a difference between adult medicine and geriatric medicine. Changing this perception demands that we confront this issue on two levels: the education of medical students, and formulating policy with regard to community medicine. Because there are very few geriatric physicians practicing in Israel today, it is hard to imagine that there will be a substantial increase in the number of geriatric specialists in the community over the next decade. Therefore, courses aimed at preparing family physicians to deal with the problems of the elderly are of great importance. Physicians treating the elderly typically have to deal with polypharmacology and multipathology and, therefore, they require specialized training for this. The psychosocial issues are of even greater importance when treating the elderly patient. Depression, which is fast becoming a very serious problem in the western world, is very typical in most elderly people, although most will refer to it as loneliness and apathy rather than depression. As the population treated in internal medicine departments ages, and this number will grow over the next decades, consideration should be given to the question of whether there have been changes in the geriatric patient population. This difficult issue ± the interaction between traditional internal medicine and geriatric medicine ± mandates serious discussion.


The coronavirus pandemic significantly – and perhaps permanently – altered the ways by which we lead our personal and professional lives. Sports journalism is no exception – with the seasons of all kinds of sports modified, reduced or cancelled entirely in 2020, reporters on the sports beat had to quickly adapt to ever-changing circumstances. This exploratory study investigates the impact of the pandemic on the practices of sports beat writers during the 2020 season. Through in-depth, semi-structured interviews with 12 beat writers covering teams in all four major North American sports leagues, this study reveals that the journalists' experiences with the pandemic-imposed conditions underscored already-present trends within sports journalism: namely, a reduction of access to players and coaching due, in part, to increased team control through robust media relations divisions; journalists' overreliance on official team sources; and a move towards feature and data- and analytics-driven stories. This study contributes to literature on sports journalism beat reporting and offers an early insight into how the pandemic conditions might help shape the future of the industry.


Objective: To compare the results and complications of monocanalicular and bicanalicular Ritleng intubation under endoscopic guidance in patients with congenital nasolacrimal duct obstruction. Methods: This prospective study was performed on 24 patients with congenital NLD obstruction in the age between (2-5 years), divided into 2 groups. Group (A) underwent monocanalicular intubation, while group (B) underwent bicanalicular intubation. Results: 11 patients out of 12 were free of symptoms and signs in each group with equal success rate in each group (91.6%). However, more complications occurred with bicanalicular Ritleng intubation as stent displacement and punctual laceration. No unplanned silicon tube removal was needed. Corneal erosion and granuloma formation were not reported in either group. Conclusion: Monocanalicular Ritleng intubation seems to be as effective as bicanalicular intubation for treatment of congenital NLD obstruction, but monocanalicular intubation seems to be safer, easier, shorter procedure with less complications. Introduction Congenital nasolacrimal duct obstruction (CNLDO) is a common problem in children, occurring in 6% or more of all newborn infants [1,2]. The usual cause is failure of canalization of the epithelial cells that form the nasolacrimal duct as it enters the valve of Hasner [3]. Spontaneous resolution occurs in 80-96% of affected infants [1,34]. Within the first few months of life, standard management of CNLDO includes hydrostatic massage of the lacrimal sac and use of topical antibiotics. An equally satisfactory approach is conservative management up to 9-12 months of age awaiting spontaneous resolution [5], followed by hospitalbased probing for persistent obstruction. Although it is unclear whether probing is less successful when delayed either by choice or by late presentation, most studies have concluded that the success rate of probing decreases with age. Probing could be less successful in older children perhaps because of prolonged inflammation of nasolacrimal system resulting in scarring and more severe obstructions with time [5,6-7]. Silicone intubation is a simple procedure, and a variety of instruments and modifications of technique have been devised [8,9]. The Ritleng lacrimal intubation system provides a technique for mono and bicanalicular silicone intubation without the need for the retrieval of metal probes from the inferior meatus. Recent advances in technological progress in rigid endonasal probes have increased interest in endoscopically transnasal interventions for CNLDO. Endoscopically assisted procedures also allow further nasal interventions during the procedure, with decreased surgical time [10].

graphs and e-mailed them along with a brief history to a single e-mail address at a monitored server. The e-mails were then distributed to the on-call consulting dermatologists. More than 40 military dermatologists answered the consults on a rotating basis in a "team call" approach. The percentage of total consults and diagnostic agreement between primary care provider and dermatologist were calculated. In addition, the number of other comments by the call team was determined. For the cost calculation, intertheater transfer of a patient to be evaluated by a dermatologist in Iraq was estimated to be $4000, while the cost of evacuation to the United States was estimated to be $14 082 (including the cost of lost duty days, ground transportation, airlift via helicopters and other aircraft, extra personnel required for security and transportation crews, and housing of patients during their evaluation and treatment).


An accurate and selective method for the determination of copper with 2-(5-chlorine-2-pyridylazo)-5-diethylaminophenol (5-Cl-DEPAP)as an indicator of the complexometric titration is described in the medium of acetic acid-sodium acetate at pH 5.5. The end point for copper is sharp.The amounts of copper is directly proportional to EDTA solution consumed in the range of 0~25 mg. The method has been used for the determination of copper in chemical reagents and aluminium alloy.


Due to the patients with intracerebral hemorrhage usually present the risk factors for ischemic stroke, the survivors after intracerebral hemorrhage are usually facing a high risk of recurrent intracerebral hemorrhage or ischemic stroke at the same time. There is always controversy about whether these patients should be treated with antiplatelet therapy. This article introduces the different point of views of researchers.

This paper describes the development of a physically-based multi-sensor satellite rainfall monitoring methodology employing a conceptual cloud-development model. The LMODEL (Lagrangian Model) algorithm uses geostationary infra-red imagery to characterise processes influencing cloud growth and dispersal, with separate representations for convective and stratiform elements These data drive a high-resolution semi-Lagrangian cellular model of raincloud development that is further updated against rainfall estimates from available microwave (MW) sensor overpasses using a combination of dynamic calibration and Kalman Filter approaches. A multi-resolution cloud tracking algorithm enables cloud advection to be traced to near geostationary pixel resolution while a specially developed empirical methodology is used to co-locate the MW satellite data to the high resolution model cells.


. We present our final results for the SU(3) sextet model with the non-improved Wilson fermion discretization. We find evidence for several phases of the lattice model, including a bulk phase with broken chiral symmetry. We study the transition between the bulk and weak coupling phase which corresponds to a significant change in the qualitative behavior of spectral and scale setting observables. In particular the t 0 and w 0 observables seem to diverge in the chiral limit in the weak coupling phase. We then focus on the study of spectral observables in the chiral limit in the weak coupling phase at infinite volume. We consider the masses and decay constants for the pseudoscalar and vector mesons, the mass of the axial vector meson and the spin-1 / 2 baryon as a function of the quark mass, while controlling finite volume e ff ects. We then test our data against both the IR conformal and the chirally broken hypotheses.


As software is large and sophisticate, in order to increase the productivity and efficiency of programs in programming development environments, it is necessary to support the integrated system that offers user interface integrated editing, compiling, debugging, and running steps. The key tool in such environments is an incremental translation. In this paper, in order to increase the productivity and reusability of software, the goal is to construct the integrated incremental interpretation system that supports friendly user interface with editor, debugger, and incremental interpreter. We define the new object-oriented language, IMPLO(IMPerative Language with Object) using EBNF notation, and construct the integrated incremental interpretation system using incremental interpreter of the language. To do so, we extend attribute grammars for specifying static semantics and present new action equations to describe the dynamic semantics. We executed the incremental interpretation by using analyzing the dynamic semantics and then implemented integrated incremental interpretation system with editor and debugger in C, Lex and Yacc using X windows on SUN. We obtain about 50% speedups in case of incremental execution time for example programs.


Based on the three-dimensional endocrine neuron model, a four-dimensional endocrine neuron model was constructed by introducing the magnetic flux variable and induced current according to the law of electromagnetic induction. Firstly, the codimension-one bifurcation and Interspike Intervals (ISIs) analysis were applied to study the bifurcation structure with respect to external stimuli and parameter \begin{document}$ k_0 $\end{document} , and two dynamical behaviors were found: period-adding and period-doubling bifurcation leading to chaos. Besides, Hopf bifurcation was specially discussed corresponding to the transformation of the state. Secondly, the different firing patterns such as regular bursting, subthreshold oscillations, fast spiking, mixed-mode oscillations (MMOs) etc. can be observed by changing the external stimuli and the induced current. The neuron model presented more firing activities under strong coupling strength. Finally, the codimension-two bifurcation analysis shown more details of bifurcation. At the same time, the Bogdanov-Takens bifurcation point was also analyzed and three bifurcation curves were derived.


Background: COVID-19, which originated in China, became a pandemic affecting more than 180 countries. By April 2020, India had announced lockdown in an attempt to control the spread of the virus. Lack of social interaction and apprehension about the studies had created emotional disturbances among medical students. Methods: The study was done in a medical college situated in Central Travancore, Kerala, between 2020 April 20 to May 31. Depression Anxiety Stress Scale (DASS) and Impact Event Scale-Revised (IES-R) were administered in Google forms to the MBBS batch WhatsApp groups. Results: Out of 320 responses from medical students, 239 were females, and 82 were male students. 56% of male students and 54% of female students have mild to severe depressive symptoms, 58% of male students and 54% of female students have symptoms of anxiety, and 63% of male students and 50% of female students experienced mild to severe stress.68% of males and 62% of females have higher Impact events scale. Conclusion: There is a high prevalence of anxiety and depression among medical students during the COVID lockdown period. There is a significant difference between genders in scores of anxiety, stress and impact of events. This shows the need for resilience training among medical students.


The Allies' conduct of the Great War has frequently been castigated by historians as inept and amateurish. But it is perhaps the conduct of their diplomacy which most merits this description. Until the creation of the Supreme War Council at the end of 1917 there existed, apart from a number of liaison officers, no machinery to synchronise the strategy and diplomacy of Great Britain and France other than the periodic meetings of the politicans and generals of the two countries. Yet, as David Lloyd George came to realize, these were not really conferences at all, but rather meetings of men with pre-conceived ideas who desired only to find a formula which could obscure the underlying differences of opinion from the general view. They were really nothing but a 'tailoring' operation at which different plans were stitched together. What was required was the construction of an inter-Allied General Staff, designed to examine and give advice on the changing military situation. Obviously no government could abdicate its right to issue orders, but if the Central Powers were to be defeated the Allies needed to concede that there was far more to participation in a coalition than the mere lip-service to unity involved in the periodic gatherings of soldiers and statesmen. An examination of the Calais Conference of December 1915, called at a time when Allied operations on all fronts were showing a marked lack of success, will illustrate many of the failings and dangers of this primitive form of war diplomacy.

Let $G$ be a finite group and let $N$ be a normal subgroup of $G$. Suppose that ${rm{Irr}} (G | N)$ is the set of the irreducible characters of $G$ that contain $N$ in their kernels. In this paper, we classify solvable groups $G$ in which the set $mathcal{C} (G) = {{rm{Irr}} (G | N) | 1 ne N trianglelefteq G }$ has at most three elements. We also compute the set $mathcal{C}(G)$ for such groups.


Background: Clostridioides difficile infection (CDI) is a leading cause of healthcare-associated infection and is associated with increased morbidity and mortality. Multiple strategies have been implemented to optimize the diagnostic accuracy of CDI testing algorithms. However, overdiagnosis of C. difficile colonization remains a challenge especially in the era of highly sensitive Nucleic acid amplification testing (NAAT). We implemented 2 interventions to reduce the rates of inappropriate C. difficile orders and tests. Methods: We performed a quasi-experimental retrospective study to examine the rates of all inpatient C. difficile test orders and results relative to 2 interventions between January 2018 and February 2021. We defined 3 periods: preintervention, after the first intervention, and after the second intervention. The first intervention, implemented May 2019, was a clinical decision support system (CDSS) tool to guide clinicians to order testing only if CDI criteria were met. The second intervention, implemented July 2020, was the requirement of mandatory antimicrobial team approval of PCR reflex testing for indeterminate toxin or antigen test results. This intervention included a discussion between clinicians and members of stewardship team prior to approval. To evaluate the impact of interventions on ordering appropriateness, chart review was conducted on a random subsample of 100 orders from each period. Hospital-onset CDI (HO-CDI) was calculated using CDC criteria. Results: In total, 3,004 C. difficile test orders were placed during the study period. The rates of reportable HO-CDI were significantly reduced by 57.1% (P = .003). We detected a significant reduction in the number of tests ordered over time from 11.6 to 7.51 per 1,000 patient days. (p Conclusions: CDSS tools target patients at high pretest probability of CDI. The restriction of PCR-reflex testing to the antimicrobial stewardship team is a novel effective measure to minimize the misdiagnosis of CDI. The incorporation of multiple strategies is necessary to improve the diagnostic accuracy of C. difficile testing. Funding: None Disclosures: None

"From Fresh Air to Summer Camp: Social Work Enters the Picture" traces developments occurring from about 1900 to 1926. During this period the new profession of social work coalesced, incorporated the reform spirit of the Progressive Era, began to develop rationales for programs that could best benefit residents of congested urban environments, and established numerous social agency-sponsored summer camps. The purposes of these camps varied and included improved health and weight gain, play, Americanization, progressive informal education, skill-building, and group life as a milieu for growth and change. The chapter includes descriptions of four early social agency summer camp programs: Surprise Lake Camp, Lillian Home, Camp Wise, and the camps at Harriman State Park, Palisades Interstate Park Commission (PIPC).

Self-consistent relativistic bandstructure calculations for face centred cubic lanthanum, cerium and thorium have been performed using the linear muffin-tin orbital (LMTO) method and the local spin density (LSD) approximation for exchange and correlation. Results are given for equilibrium distance, bulk modulus, spin susceptibility and the electron-phonon matrix element in each case. A significant contribution of f partial waves to the crystal bonding for all three metals has been found. At the atomic volume corresponding to the gamma phase, cerium exhibits a ferromagnetic instability.


This paper aims to provide a framework that might be used to tackle the multifaceted challenges facing humanity, which are increasing in seriousness and complexity. The Millennium Project had identified such challenges, and over time periods until and including 2050, which pose the question, how would societies cope with these challenges averting any disastrous results? contemplating the suggested ethical principles, and the three central beliefs of "end-based", "rule-based" and "care-based". In some cases, individuals might not be blamed to think that "it is only a miracle" that might save humanity.,This paper, through the use of literature review, intends to provide an insight into these challenges, the suggested ethical principles and the three central beliefs, providing brief overview of the concept "miracle" leading to discussion on ethical mindsets, its components and their dimensions.,Concluding with framework for the way forward tackling these challenges.,The limitation of this paper might lie in the fact that it is only a conceptual paper, but it calls on researchers to conduct further research using the suggested framework.,This might seem to be forward thinking, but it is a call for researchers to conduct more research in this area, and for governments to fund such research, to allow for the establishment of a method to refine the mindsets of individuals around the world to change into "ethical", and thus, the world becomes better equipped to face and reduce the challenges and threats that are being faced by the world.


This paper deals with distributed algorithms for monitoring the topology of a dynamic group of mobile wireless sensor networks. We propose two major extensions of a distributed static group consensus algorithm and an experimental implementation. Group consensus algorithms are exploited to let each node obtain the knowledge of its connected com-ponents. The proposed extensions provide a more accurate information about the proximity of nodes and allow to deal with dynamic networks using a periodical reevaluation of the group detection. We validate these algorithms by implementing them in an original and challenging application scenario, in the context of a real bicycle race. The real traces thus obtained and analyzed show the effectiveness of our live group detection implementation.


BACKGROUND
Neglected tropical diseases (NTDs) are infectious diseases that mostly affect people living in tropical and subtropical regions, especially in impoverished areas. Ubiquitously found in plants, flavonoids are a group of compounds which have been reported to exhibit a wide range of biological activities against parasites (Leishmania sp., Trypanosoma cruzi, Trypanosoma brucei, Brugia malayi, etc.) that cause certain NTDs.

AIM OF THE STUDY
The present study aims to highlight and discuss our recent reports on the implication of flavonoids in drug development for NTDs, such as leishmaniasis, Chagas disease, African trypanosomiasis, filariasis, among others.

RESULTS
Today, studies show that flavonoids exhibit in vitro antileishmanial, anti-trypanosomiasis, antifilarial activities, among others. Furthermore, the molecular hybridization of flavonoids with the triazole groups has led to the development of compounds with improved biological activity. The incorporation of chemical groups, such as NO2, F, and Cl groups during the process of design and synthesis lead to the enhancement of the pharmacological activity.

CONCLUSION
Flavonoids are useful metabolites which can be prospected as potential leads for the development of new agents against certain NTDs. However, research opportunities, including cytotoxicity and in vivo studies, mechanisms of action, bioavailability of these compounds remain to be investigated in future.

Campaigning groups are challenging patent applications for the blockbuster hepatitis C drug sofosbuvir (Sovaldi) in Argentina, Brazil, China, Russia, and Ukraine to improve access to the drug.

I-MAK, a US based group that campaigns for increased access to affordable medicines, has claimed that Gilead Sciences, the US biotechnology company that makes Sovaldi, is seeking "illegitimate patents" for sofosbuvir and "blocking millions of people around the world from getting the treatment" for hepatitis C.1

The group alleged that the base compound in sofosbuvir is not new and is already covered by earlier patents. I-MAK, together with an Indian organisation, Delhi Network of Positive People, opposed the patent application for sofosbuvir in India on the grounds that no new evidence showed it to have enhanced efficacy over known forms of the compound. India's patent office rejected the application for sofosbuvir in January on the grounds that sofosbuvir …

The theoretical approach of the previous paper [J. Chem. Phys. 56, 3874 (1972)] is applied using the potential surface of Shavitt et al. [J. Chem. Phys. 48, 2700 (1968)]. Total reactive cross sections were found to be monotonically increasing functions of translational energy virtually independent of initial rotational state. Reactive angular distributions were forward and back peaked with peaks shifting with energy and product rotation. Nonreactive differential cross sections were back peaked. The rate constants agreed in order of magnitude with classical and transition state theory calculations and with experiment, but showed evidence of large amounts of tunneling. At low temperatures, they were dramatically influenced by the threshold form of the cross section assumed.
