This work was performed at the Center for Agricultural and Environmental Sciences at the State University of Paraiba and aimed to assess the influence of manipueira the germination process in seeds of lettuce (Lactuca sativa L.). Design was used entirely causualizado (DIC). Lettuce seeds were immersed in solutions manipueira 0, 5, 10 and 15%. We analyzed the germination speed index (GSI) and percentage germination. It was noted that with increasing concentration of manipueira occurs inhibition of the germination process, while immersed in water when the process is accelerated. We conclude that the imbibition of lettuce seeds in water is an effective alternative for the production of seedlings.


Abstract This article unravels the proliferation of 'fashion' with respect to clothing over the last half-century, putting the British perspective in the context of wider changes in European and American fashion production. Design innovation patterns evolved in the post-war world in response to growing markets and changes in social conditions. The concepts of 'design monopoly' and 'collective screening' are used to explain this phenomenon, with evidence from designer associations, trade exhibitions and international fashion shows to support this story. This article aims to offer a holistic account of interrelationships between haute couture and high street fashion and illustrates how the global fashion system has evolved.

The objective of this study is to develop statistical models to predict the depth limit stop of water drilling in crystalline and crystallophyllian rocks using physical parameters of drilling. The study was conducted using data from physical parameters (depth of drilling, depth of the first water supply significant, alteration thickness and thickness of base drilled) from geological units of Archean and Paleoproterozoical domains of Ivory Coast. The methodology consisted of first analyze the physical parameters from the simple statistical features and frequency class distribution of these parameters. Then, a normalized principal components analysis (NPCA) was applied for the identification of explanatory variables relevant and expressive of drilling depth limit. Finally, a calibration was performed with a sample of 1,605 wells representing two thirds of the total sample to determine the coefficients of the linear regressions and the associated standard errors. The analysis of the distribution of physical parameters of drilling shows that only the depth of drilling is homogeneous (24.50%) with an average of 68.17 m. The most relevant and expressive variables for predicting the depth limit stop of water drilling in crystalline and crystallophyllian rocks are the depth of the first significant water arrival and the thickness of alteration. The errors associated with the regression coefficients generally low (below 1%) reflect the close relationship between the dependent variables and the explanatory variables. Two models for predicting the depth limit stop of water drilling (PROLIFE models) in crystalline and crystallophyllian rocks were developed.


The Russian sinologist Wassiljew, in his 1856 book Buddhismus (1860, 119), quoted the opinion of Tschantscha Chutuktu: "The first five of twelve aṅgas form the Sūtras of Hīnayāna, the following four the part of Vinaya (...) and the last three belong to the Sūtras of Mahāyāna." This is almost the same as recorded in the Abhidharmasamuccaya (T 1605 686b25–c3). But in the Śrāvakabhūmisūtra, only the nidāna belongs to Vinaya-, upadeśa to the Abhidharma-, the other ten to the Sūtra-piṭaka. This is the same in the Abhidharmasamuccayabhāṣyam (T 1606 744a13–23), but avadāna etc. is treated as the appendix of the Vinaya.


ALTHOUGH BCG vaccine has been used widely as an immunizing agent for over 25 years, there remain many problems dealing with its preparation, preservation, and standardization. The differences in results obtained by various investigators, with special reference to dose of vaccine, character of the local reaction and incidence and persistence of the post-vaccinal tuberculin reaction, make it advisable to study more precisely the technique used in the preparation of BCG vaccine and to develop methods for evaluating its potency.


New Ni-based superalloys and methods for controlling their microstructures have recently received much investigation to further improve their high-temperature properties, sometimes via control of precipitates such as γ' (Ni3(Al,Ti,Nb,Ta)) and γ″ (Ni3Nb). In Ni-based superalloys, fine grains favor deformability and mechanical properties; therefore, control of grain size, achieved by recrystallization, is also important. Some new studies have reported the pinning effects of coarse γ'. However, few studies have investigated modeling methods for recrystallization behaviors. Difficulties in grain size and phase distribution control have hindered fabrication by open-die forging utilizing the pinning effect of the γ#x2019; phase. Therefore, this study examines the recrystallization behaviors of Ni-based superalloys containing coarse primary γ' precipitates and considers applicable modeling methods. The recrystallization behaviors at sub-solvus temperatures are investigated in a new Ni-based superalloy with abundant coarse γ' precipitates. Grain growth is limited by the pinning effect of coarse γ' and the recrystallized grain size corresponds to increasing applied strain. Dynamic and static recrystallization is promoted by high strains and high temperatures. The kinetics of the recrystallized area fraction and recrystallization grain growth influenced by the pinning effect of coarse γ' is modeled by Zurob's method.


The purpose of this work is to apply the new popularity-gaining optimization method of Cuckoo search for the problem of choosing the optimal location of static thyristor compensators and the volume of reactive power compensation in the radial power system and comparison with the proven method of optimizing the particle swarm.The most widespread among all FACTS-devices received static thyristor compensators (STC). The STC monitors the voltage on the bus to which it is connected by generating or consuming reactive power.The method of cuckoo search distinguishing feature is a small number of initial conditions affecting the operation of the algorithm, which makes it more versatile than many other algorithms. Calculation of the steady-state regime for real power systems is impossible without taking into account a number of regime constraints.Calculations of the operation modes of the electric network after carrying out typical activities and analysis of the obtained data show that often used in the enterprises of the BSC to compensate the reactive power do not always give the expected result.The performed calculations made it possible to obtain an estimate of the voltage levels on the tires of final consumers. The results of such studies can find application in the development of new information and computer systems for controlling the operation modes of an electrical network with actively-adaptive elements.

In this research, in order to study some physiological and molecular traits such as the expression level of Catalase (CAT1) and Ascorbate Peroxidase (APX1) genes in two, CHFalat and Rio Grande-S, varieties of tomato plant (Solanum lycopersicum L.), an experiment was designed in randomized complete block design. Salinity with the concentration of 0, 25, 50, 75 and 100 mM NaCl was applied in hydroponic culture. Plants RNA was extracted and cDNA was synthesized, then Real–Time PCR was carried out. The results showed that the relative expression of CAT1 has been increased in Rio Grande-S at all levels of salinity and in Falat-CH variety only up to 50 mM NaCl. The relative expression of APX1 has been decreased in Rio Grande-S up to 50 mM of salinity level and has been increased in 75 and 100 mM salinity levels. The relative expression of APX1 in Falat-CH variety has been increased up to 50 mM salinity level. Some physiological traits in salinity treatments were also studied and the results showed that in both varieties, by salinity increase from 0 to 100 mM NaCl, the amount of Na, Prolin, the soluble sugers were increased and the amount of K, and K/Na were decreased. The membrane stability index was decreased in salinity treatments comparing to control. The results of the molecular and physiological analysis showed that Rio Grande S variety in comparison to CH-Falat is more resistant under high level of salinity.


The Constant Bandwidth Server (CBS) is one of the most used algorithms for implementing resource reservation upon deadline-based schedulers. Although many CBS variants are available in the literature, no proper formalization has been proposed for the CBS in the context of hard reservations, where it is essential to guarantee a bounded-delay service across applications. Existing formulations are affected by a problem that can expose the system to dangerous deadline misses in the presence of blocking. This paper analyzes such a problem and presents a comprehensive and consistent formulation of the CBS for hard reservation scenarios. An overview of the contexts in which a hard CBS can be applied is also provided, focusing on the impact that previous formulations can have on schedulability, when used in conjunction with specific resource sharing protocols or other scheduling mechanisms that may cause a server to block.


Several types of differential pressure based flowmeters are currently being used in wet gas flow measurement. Differential pressure based flowmeters share many performance characteristics in wet gas applications. However, studies have also found that there can be significant differences in the correlations between meter over-reading and liquid content depending on the type of differential pressure meter being tested.


The current market practices for most capital equipment manufacturers provide them with some special difficulties in production management tasks. These are, mainly: 1. Design changes during the necessary overlapping of the production process. 2. Some degree of uncertainty with supplier's due dates and quality specifications accomplishments. 3. Sensibility of changes and other incidences in the current schedules that operates at the shop floor level. 4. Warnings of a chaotic behaviour in both due-dates and productivity originated by a delay between the coupling of the rescheduling of operations at the shop-floor level and the planning process at the office level. Advanced technology for facilitating integration, lay the concept of the MRP-3, a new production management system specially indicated for the "minibusiness" model of a factory, and which is probably going to give a leap in the next future to the organisational procedures in discrete manufacturing, and in particular in OKP. 1. OBJECTIVES Regarding all that issues, the objectives of the paper are: 1. To establish a reference-model for the utilisation of the MRP-3 system for one to twelve months of lead-time (intermediate lead-times) OKP facility. 2. To make a functional design approach of the MRP-3 in OKP. The reference model is used as an organizational issue leading the way in wich a particular OKP company must interact with the MRP-3 software. Key issues for that are:-The planning integration as a part of the Engineering department.-The "coordination technology" engineer who is going to set and facilitate information structure along the project.-Prompt definitions of the FAS (final-assembly-schedule) and BOP (bill of processes), with assignation of critical materials to each BOP's gantt bar. 2. INTRODUCTION MRP has been largely used in OKP eventually in conjunction with the PERT-CPM. When done, a common practice is performing the first order BOM calculation based on the critical path nodes of the PERT, and the second order BOM is coupled using due date tolerances around the first order calculated ones.This is mostly a tuned and relatively advanced practice, requiring one way (from PERT to MRP) software integration. But the inconvenients are the following ones:. The PERT (or GANTT-BAR correspondent deployment) is lost as a major way of communication along the company due to the breaking from "phases" into "bills of materials". The phases planning is the most natural way of communication at the shop floor level and with the planning-engineering department.. Plant capacity scheduling and rescheduling are not …

A petroleum company's operations are a function of many teams that cannot exist in isolation as roles and tasks integrate, especially within the planning, scheduling, and logistics team. The information that is supplied, and used, and the decisions made by these stakeholders are what make the business function. The problem that exists in the organisation's supply chain cycle is the lack of data transparency across the teams. The data is stored and managed by each individual division manually, resulting in a lack of integration causing a discontinuity in the process flows. This study analyses the importance of using a Value Stream Mapping (VSM) in planning, scheduling, and logistics processes at a petroleum company that is part of a joint venture refinery and its importance in an integrated digital system. The major findings from using Value Stream Mapping (VSM) are the value of time and costs in improving efficiencies, the appreciation of the existing technologies used in the petroleum industry, and the importance of using integrated digital technologies to improve systems. The study concludes that using an improved VSM to integrate the digital system is vital in the supply chain for both internal and external use in the organisation as the 4th Industrial Revolution (4IR) systems require rapid responses.

Abstract Radiosensitive neurogenic stem cells reside in the hippocampi, suggesting that avoidance of the hippocampi may be an important strategy to reduce potential radiation-related cognitive effects. Six patients treated for base of skull tumours were re-planned using co-planar helical fan beam arc therapy (tomotherapy) and co-planar and non-coplanar volumetric arc techniques (RapidArc). The hippocampi were contoured as avoidance structures with the specific goal of minimising the dose. Two gross target volume (GTV) to planning target volume (PTV) expansions (10 and 2 mm) were considered to evaluate the impact of margin selection on organ at risk (OAR) sparing. The dose prescription was 50 Gy to >95% of the PTV. Comparison of the hippocampus avoidance plans demonstrated the importance of non-coplanar delivery when the 10 mm margin was used. With the 2 mm margin, both co-planar and non-coplanar delivery provided similar degrees of sparing. A mean dose of 3–4 Gy and a V6Gy <5% to the hippocampi was realised with the hippocampus sparing techniques. Our comparisons suggest interventions to minimise GTV to PTV margins will have a more profound influence on multiple OAR sparing than the choice of intensity modulated arc delivery technique.


Examines the causality issue, in a Granger‐temporal causal sense, between price level and productivity in a bivariate and multivariate context in Greece over the period 1962‐1997. The empirical analysis employs various time‐series techniques such as unit‐root testing, bivariate and multivariate cointegration and procedures in vector error‐correction modeling (VECM). The empirical results suggest that a bivariate relationship between inflation and productivity is spurious, as the unit root pre‐tests that account for oil shock episodes show that inflation and productivity are integrated of a different order. When we control for fluctuations of overall economic activity and monetary policy on the bivariate relationship between price level and productivity, the evidence suggests that Granger‐causation must exist in at least one direction. VECM estimation showed that productivity growth and inflation are an econometrically endogenous variable and this suggests that bi‐directional causality from inflation to productivity growth and vice versa exists.

Epidemiology Thyroid nodules are approximately 4 times more common in women than in men. Palpable nodules increase in frequency throughout life, reaching a prevalence of approximately 5% in the United States population aged 50 years and older.1–3 Nodules are even more prevalent when the thyroid gland is examined at autopsy or surgery, or when using ultrasonography, and 50% of these have nodules, which are almost always benign.2,4 New nodules develop at a rate of approximately 0.1% per year beginning in early life, but at a much higher rate (~2% per year) after exposure to head and neck irradiation.5,6 By contrast, thyroid carcinoma is uncommon. For the United States population, the lifetime risk of NCCN

The article raises questions of a historical and cultural nature related to the activities of cultural and leisure institutions of the city of Izhevsk in the Udmurt Republic. One of the features of Udmurtia is its multi-ethnicity. More than 130 nationalities live in this republic. Modern trends connected with the construction of a common world space actualize the problem of preserving the ethno-cultural field, which is a unique example of folk culture. The main attention is paid to the history and main lines of activity of MBIC HC "Vostochny", which is the Center for cultural services for the population of the "Vostochny" microdistrict of the Industrial District of Izhevsk. The House of Culture has been in existence since 1949. By the moment the House of Culture has created all the conditions for the development of the creative abilities of people of different ages, and the audience has a wide choice of different kinds of performances. One of the main directions of the "Vostochny" House of Culture is work in the field of development and preservation of ethnic traditions and culture. For several years effective cooperation has continued with the Izhevsk city branch of the All-Udmurt Association "Udmurt Kenesh" Interregional Public Organization. Together with this organization the "Vostochny" House of Culture organizes and holds some national festivals and cultural events dedicated to various state dates and public holidays. In the House of Culture one of the leading Udmurt amateur art group of the city of Izhevsk is based - Laureate of the Kuzeby Gerd Prize Folk Ensemble of the Udmurt song "Invozho". Also within the walls of the "Vostochny" House of Culture another national group works - the Folk Ensemble of the Mari song "Osh Peledysh" ("White Flower"). This ensemble is an active participant in international events, where it acquaints the audience with their work filled with a special ethical flavor. Thus the activity to preserve ethnic traditions and popularization of folk culture is a very important area for many cultural and leisure institutions. Studying folklore and giving it different scenic forms makes it attractive to a wide audience of different ages. Despite many problems (primarily financial) folk groups search for new forms of studying ethnic material.


The purpose of this study is to propose a simple model based on organizational theory which can be used to discover the educational goals selected by teachers to guide their classroom behaviors. The major organizational characteristic examined is the age-grade structure of schooling. The educational goals of teachers are broadly classified as technical or moral goals. The technical goals reflect the cognitive goal emphasis of teachers (e.g., the development of competence by students to perform basic reading and arithmetic tasks), while the moral goals of teachers reflect affective educational objectives (e.g., the development of commitment by students to the broad of values society). The age-grade structure of schooling was examined as a possible organizational characteristic that may influence themoral and technical goals selected by teachers for emphasis in their classrooms. The focus of this study is on the ddscovery of the intended goals of teachers and the impact which the social organization of schooling has on these goals. This study is viewed as the first step in a more complete analysis of the role of goals in schools viewed as social organizations which would include an examination of the implemented goals as well as the goals internalized by the students. In order to provide a preliminary examination of ths proposed model, 70 elementary school teachers in public and Catholic schools in the metropolitan Chicago area were asked to indicate the degree of emphasis which they place on the learning of a set of moral and technical goals in their classrooms. There is some support for the idea that age-grade structure has an effect on teacher goals, however further research is needed on how teachers actually select and implement educational goals.


The outbreak of the new crown epidemic has had a serious impact on the social and economic development of China and Kazakhstan, and the power of digital technology has become prominent in the process of fighting against the pandemic and recovering the economy. The pandemic has created new opportunities for the development of the global digital economy, and also provides a new opportunity for China and Kazakhstan to jointly build the "Digital Silk Road". Meanwhile, under the background of the pandemic, China and Kazakhstan face many challenges to jointly build the "Digital Silk Road", including political risks, digital governance and security, third country interference and other obstacles. In the future, China and Kazakhstan can start cooperation by improving the risk assessment system, strengthening the level of digital governance, and strengthening China-Kazakhstan strategic mutual trust, so as to accelerate the construction of the "Digital Silk Road" between China and Kazakhstan.


The Y 2 O 3 :Eu films were prepared on sapphire substrates by radio frequency magnetron sputtering. The samples were post-annealed in an air ambient at different temperatures. The Y 2 O 3 :Eu films prior to annealing did not show photoluminescence (PL), however, after annealing, the films became capable of emitting photoluminescent light. The PL spectra were composed of several peaks originating from the transitions between 4 𝑓 energy levels of the Eu 3 + ion, from 5 𝐷 0 to 7 𝐹 𝐽 where 𝐽 = 0, 1, 2 ,3, and 4. The PL intensity increased upon annealing at higher temperatures, which was due to the higher degree of crystallinity. The PL intensity decreased above 1200 ○ C resulting from the formation of yttriumaluminatephases, suchasYAM(Y 4 Al 2 O 9 ), YAP(YAlO 3 ), andYAG(Y 3 A l5 O 12 ). TheunannealedY 2 O 3 :Eufilmsexhibitedahighoptical transmittance in the visible to near-infrared wavelength range. The transmittance of the films decreased as annealing temperature increased due to increase in crystallite sizes.


This thesis is an integrated and interdisciplinary study of 275 lead cloth seals dated from the mid-fourteenth to the early-nineteenth centuries. These recently discovered objects, recovered from a single submerged river-bed site located in the North-East of England, were once linked to the trade, industrial regulation and taxation of commercially produced cloth. They are presented here, catalogued and illustrated. These objects represent the largest assemblage of such material outside London and are of crucial significance for understanding the cloth trade in the late- and post-medieval period. Due to the unusual deposition conditions from which the objects were recovered, rare scraps of textiles have survived in many of the cloth seals. A range of scientific and analytical analyses was undertaken on three cloth seals containing textiles revealing important information. For the first time in the UK, ultra-high performance liquid chromatography (performed at The Centre for Textile Conservation and Technical Art History, Glasgow University) was successfully used to extract colourants related to dyes from textile fragments preserved in lead cloth seals. This significant new information provides new insights into textile availability, trade and the consumption of cloth, mordants and dyestuffs in the late-sixteenth to early-nineteenth century.

Evidence from the cloth seals is combined with other documentary, cartographic and archaeological sources of evidence to produce a synthesis providing new understanding of the cloth trade in Durham in the late- and post-medieval periods. The research generated by this thesis has demonstrated not just the scale and extent of textile production in the City of Durham, but has also revealed evidence of hitherto unknown English and European trade routes.


The first exploration in the Ruston field area that indicated the presence of a structural feature was a reconnaissance surface survey by the Arkansas‐Louisiana Gas Company in 1931. This paper, with maps, describes the surface work and the subsequent reflection seismograph surveys conducted by Arkansas‐Louisiana Gas Company in the area prior to the discovery of gas in the Cotton Valley formation. A comparison of the results of the surface and seismic work is made with the structure as revealed by present subsurface control.


To understand video games as learning envnironments, it is essential to look carefully at the qualitative descriptions of learning in video game environements and apply to it what we know from learning theory about how people think and learn. An ecological psychology view of learning from video games would highlight 9 principles focusing on the primacy of goals and intentions that guide perception-action within the constraints of the game design and user interface. From an ecological perspective, then, the task of game design becomes one of selecting goals and creating environments in which those goals can optimally be pursued, while taking into account those things that gamers tell us are keys to enjoyable, engaging experience.

Three inspirations are got about the reforming of land system,which are: first,criticizing 3 basic models' merits and demerits about the land system reforming(improvement model,privatization model and complete nationalized model),pointing out that a perfect balanced point must be sought between government's macro-economic control and marketing system when innovating land system,to make human beings and land develop integrated and harmoniously.Second,clear property rights are the basis of successfully reforming land use system.Third,establishing reasonable land earnings collocation system is the key to it.


The purpose of this study is to explore the practices of knowledge sharing in a Thai private hospital intensive care unit (ICU) nursing team. This study selected a constructing grounded theory strategy. Purposive sampling and theoretical sampling including grounded theory interviewing and an in-depth interview are used to collect data from the 29 participants who consisted of senior and novice nurses in the same Thai ICU until the theoretical categories were saturated. The findings were initially open codes and these were developed as concepts and categories. A total of seven main categories were identified as: (1) A Nurse's Necessary Knowledge; (2) Knowledge Resources; (3) Method of Knowledge Transformation; (4) Process of Knowledge Transformation; (5) Facilitating Knowledge Sharing in the ICU; (6) Obstacles to Knowledge Sharing; and (7) Feelings towards Knowledge Sharing. Moreover, this study provided a more detailed picture of the knowledge that a Thai ICU nursing team shared with one another. One unexpected finding was that some nurses did not disclose the information as much as they should have done, although it was the part of the hospital's plan to teach the nurses certain things when they joined a department. Administrators should create a culture of caring and sharing in order to contribute to the voluntary sharing of knowledge and the willingness of nurses to work in a hospital ICU.


Background: Indigenous women residing in remote communities experience a disproportionately higher prevalence of nutrition-related chronic diseases. The development of evidence-based programs and policies to minimize these health disparities necessitates a comprehensive understanding of Indigenous women's nutrition status and dietary intake patterns. However, a knowledge gap exists with respect to baseline maternal nutrition status and dietary intake information among First Nations women living on reserves. Objective: We aimed to systematically synthesize existing literature on maternal dietary information in Indigenous women residing on reserve lands and remote communities. Methodology: The articles that reported a singular nutrient status, multiple nutrients status, meal consumption pattern, and/ nutrition-related biomarkers in First Nations women during childbearing years, pregnancy, and lactation were synthesized for this review. Results: Major nutrient deficiencies identified were fiber, folate, vitamin A, D, and E, calcium, potassium, and magnesium; low consumption of vegetable and fruit, grain, and milk and alternative food groups was observed. A lack of information on maternal nutrient status in maternal, First Nations, on-reserve population obstructed nutrition status evidence appraisal. Conclusion: We recommend that a greater emphasis be placed on improved maternal nutrition surveillance systems, which are designed in partnership with the Indigenous organizations. Development of a sustainable community nutrition monitoring system will allow for the construction of the nutrition information capacity.


Powerful AC plasma torches are in demand for a number of advanced plasma chemical applications, they can provide high enthalpy of the working gas. IEE RAS specialists have developed a number of models of stationary thermal plasma torches for continuous operation on air with the power from 5 to 500 kW, and on mixture of H2O, CO2 and CH4 up to 150 kW. AC plasma torches were tested on the pilot plasmachemical installations. Powerful AC plasma torch with hollow electrodes and the gas vortex stabilization of arc in cylindrical channels and its operation characteristics are presented. Lifetime of its continuous operation on air is 2000 hours and thermal efficiency is about 92%, the electric arc length between two electrodes of the plasma torch exceeds 2 m.


With the advent of technological sensor devices and human interface machine technology, there has been extensive research done in lip segmentation methods by several researchers — some linguistic features required for interaction with the machine equipment. Therefore, research work has been done in the audio speech detection scheme for recognition of lip reading. Visual lip reading technology developed based on the extraction of features of the lip. Lip segmentation is an essential approach to recognize lip reading scheme. Meanwhile, it helps to improve parameters. Several methods studied to segment the lip area based on localized active contour method using twice contour finding and combined color-space method. Apply the illumination histogram equalization to real color images to reduce the distortion of uneven illumination. The proposed method implemented can get better accuracy rate and segmentation results and compare with the existing process using area or circle as the region to segment grayscale images and combined in the color-space image. Using SIFT and BPNN, the inner region of the lip found in the result. The experiment tool is used MATLAB 2016a and designs a PROJECT APPLICATION. Improve the success rate and reduce the segmented error and compared with the current metrics. The experimental analysis determines the accuracy rate with 94%; error rate reduces with Segmented Error % and Overlap Error rate value with 79.73%.


The Capgras syndrome, first described by Capgras and Rebould-Lachaux (1923), is the name applied to a peculiar delusional system in which the patients come to believe that persons well known to them—usually close relatives—are impostors who have assumed the exact appearances of those whom they have supplanted. The majority of examples of this condition have been observed in schizophrenic patients but, like most eponymous titles in medicine, the term was applied to a disease pattern that failed to fit conveniently into existing classification. Most branches of medicine, with the gradual accumulation of new information, pass through an 'identification' phase when new syndromes are being discovered. A further 'synthesizing' phase is eventually reached when researchers, equipped with greater knowledge regarding likely aetiology, pattern of symptoms and treatment, are able to appreciate the wider implications and ramifications of the problem, as well as uncertainties surrounding the initially identified disease pattern. In psychiatry, titles that emphasize specific patterns of symptomatology tend to be the rule rather than the exception, but advances in psychopathology, neuropsychology and neuropathology imply a need for reassessing the contribution of a purely phenomenological approach to the problem. Such an approach may well be overdue as far as the Capgras and other syndromes are concerned. The following case is presented in the hope that the condition, when it is recognized, will be evaluated in terms of its aetiology, and that attention will be paid to the more fundamental questions of psychopathology and related patterns of neuropsychological function.


The Hajj has become the epicenter of mass migration of millions of Muslims of enormous ethnic diversity. No other mass gathering can compare, either in scale or in regularity. Respiratory tract infection during Hajj (pilgrimage to Mecca) is a common illness, and it is responsible for most of the hospital admissions. Influenza virus is the leading cause of upper respiratory tract infection during Hajj, and pneumonia can be serious. Taking into account the close contacts among the pilgrims, as well as the crowding, the potential for transmission of M. tuberculosis is expected to be high. Although vaccination program for influenza is implemented, its efficacy is uncertain in this relus season. Future studies should concentrate on prevention and mitigation of these infections.


Sequence generation is one of the state-of-the-art topics in recent days, where given a sequence of inputs, the aim is to generate a similar sequence of outputs in a given context. The applications range from sentence autocompletion in mail bodies to text suggestions for automatic replies, etc. A similar idea can therefore be utilized to generate a sequence of musical notes using some LSTM/GRU based architecture, where we train our model based on given sequences of musical notes. If we look at music of a certain genre, it's simply a time series data where the data is in frequency domain. Fortunately for musicians these frequencies have a notation, which can serve as texts to train any given time series model. Hence, in this paper we propose a Char-RNN based model which can understand the patterns in each composition or a raga and generate new piece of music based on that. The model must not simply copy paste the sequence or generate any random note at a given instant of time but be capable enough to grasp the patterns in which the given piece of music is based upon and create a similar, new piece of music out of that.


We demonstrate pulse compression from 300 fs down to 17 fs up to 20 kHz using multidimensional solitary states in a hollow-core fiber filled with molecular gas in differential pressure to mitigate thermal effects.


The paper shows that the system "A Standard Omnidirectional Antenna - Metal Body of the Helicopter" becomes non-parametric system at rotation of main rotor. Under this condition the effective height of the antenna is the parametric factor. Distortions of the spectrum of radio signals on the input of the standard antenna are consequence of periodic changes of the effective antenna height. In the paper, the method of analysis of signal spectrum after parametrical distortions is developed, namely: quantitative estimation of attenuation of spectral components of useful signal and detection of combination frequencies of unwanted components-satellites. Spectral distortions of some types of modulated and manipulated signals on the output of parametrical antenna system are also considered.


Research on carbon storage is currently in the world spotlight along with the increasing greenhouse effect. Mangroves as one of the ecosystems play a role in blue carbon which can store more carbon than terrestrial forests. Mangroves absorb more carbon than any other forest ecosystem. This is because mangroves are included in wetlands that have the ability to store carbon when the land remains wet. An in-depth discussion was carried out by integrating various literatures on mangroves from 2011–2021 to enrich the information for this research. Mangrove area in West Kalimantan in the period 2011 - 2021 has an area of about 256,586.80 Ha which is dominated by species Brugueira spp., Rhizophora spp., Sonneratia alba, Avicennia spp. Nypa fruticans, Excoecaria agallocha, Xylocarpus moluccensis and Acrostichum speciosum. Human activities, abrasion and sedimentation have caused a decrease in the area of mangrove ecosystems in West Kalimantan. An increase in temperature has a global impact on life on the earth's surface and the environmental conditions of mangroves. The decrease in micropopulation and aboveground biomass causes a decrease in infauna species and biomass, affects nutrient cycles, destroys nurseries, and reduces mangrove ecosystem services. The results show that mangrove carbon storage in the period 2011 - 2021 is 628.10 tons C.ha-1 which has an economic valuation of 3,410.50 US$. Efforts to mitigate global warming and trade in mangroves can be carried out through community-based restoration, restoration of forest plantings, integrated coastal ecosystem rehabilitation, and economic approaches.

A large literature has developed on the electroretinogram (e.r.g.); for the most recent review see Crescitelli (1960). Structures generating the various components, however, are still not clearly identified. This problem must be solved before the significance of the e.r.g. in the visual process can be understood and before the e.r.g. can be accurately interpreted as a tool for visual research or clinical diagnosis. A number of investigators have now attacked this problem by using micropipette electrodes to record the intraretinal potentials of the frog retina (Tomita, 1950, 1959; Tomita, Funaishi & Shino, 1951; Tomita, Mizuno & Ida, 1952; Ottoson & Svaetichin, 1953; Brindley, 1956, 1958, 1960; Tomita & Torihama, 1956; Tomita, Murakami & Hashimoto, 1960). Agreement has not resulted from these studies, however, and results as well as interpretations have sometimes differed sharply. Brindley (1956) has shown that lack of agreement is due at least partly to difficulties of working with retinas which have been removed from the animal. The technique of using micropipette electrodes in the retina of the intact mammalian eye solves certain technical problems (Brown & Wiesel, 1959). This preparation can be maintained in normal physiological condition for one or two days. Methods have also been developed in this preparation for determining the location ofthe electrode tip by physiological criteria; these methods are at least as accurate as electrode staining procedures (Brown & Tasaki, 1961) and give immediate informatiGn about electrode depth. In a previous paper the dark-adapted cat e.r.g. has been analysed into four major components (Brown & Wiesel, 1961). In addition to the well known a-, b-, and c-waves, there is a d.c. component which is positive in polarity with conventional recording methods. All these components have also been identified in the local e.r.g. (designated the l.e.r.g.) recorded by an intraretinal electrode. Each component of the e.r.g. seems to be

In addition, the examples are also presented. As to the special requirements, the client application based on URL is stressed and JSSE debugging methods are introduced.


Her dad's unusual ability to keep playing like a child, as well as his choice to resist adults' rules, made him a memorable playmate. AsWalls andher siblings grewolder, her parents' refusal to accept rules andboundariesmade daily life very difficult. After strenuous effort, the children broken away from their parents and started lives of their own within more conventional boundaries. One spring day in New York City, while on her way to a party in a taxi,Walls saw her mother pulling trash out of a dumpster. Feeling embarrassed and sad, she asked the taxi driver to take her home to Park Avenue. Later, when she told her mother how uncomfortable she felt, her mother said, 'Your father and I are who we are. Accept it' (5). She also said that her daughter should tell the truth. Walls takes her mother's advice and tells the truth about her family's challenges and joys. She thanks her mother for believing in art and truth and her father for dreaming big dreams. Although she does not thank her parents for letting her play as freely as she wanted to, it is clear that this freedom was crucial. After playing with fire, creating 'nuclear fuel,' and fighting lettuce wars, she felt strong enough to handle whatever else might come up. Like Brian Sutton-Smith, she remembered her wild childhood play and made it part of her work. Her father, both a play companion and a giver of stars, gave her a kind of inspiration that is good to keep in mind as our new year moves forward.


Graphene has attracted the interest of many researchers due to various its advantages such as high mobility, high transparency, and strong mechanical strength. However, large-area graphene is grown at high temperatures of about 1,000 °C and must be transferred to various substrates for various applications. As a result, transferred graphene shows many defects such as wrinkles/ripples and cracks that happen during the transfer process. In this study, we address transfer-free, large-scale, and high-quality monolayer graphene. Monolayer graphene was grown at low temperatures on Ti (10nm)-buffered Si (001) and PET substrates via plasma-assisted thermal chemical vapor deposition (PATCVD). The graphene area is small at low mTorr range of operating pressure, while 4 × 4 cm2 scale graphene is grown at high working pressures from 1.5 to 1.8 Torr. Four-inch wafer scale graphene growth is achieved at growth conditions of 1.8 Torr working pressure and 150 °C growth temperature. The monolayer graphene that is grown directly on the Ti-buffer layer reveals a transparency of 97.4 % at a wavelength of 550 nm, a carrier mobility of about 7,000 cm2/V×s, and a sheet resistance of 98 W/□. Transfer-free, large-scale, high-quality monolayer graphene can be applied to flexible and stretchable electronic devices.

This research uses quantitative methods of data collection using a questionnaire that distributed to Civil Engineering students who are still actively using Google Classroom. Determination techniques for sample is using random sampling techniques. This results shows that the effectiveness of Google Classroom in Civil Engineering is considered very effective. This has been proved by the results of the data collected have been measured by six indicators, which are Receiver, Content, Media, Format, Source and Timing. The result is highly effective on a scale of 4.36, which means that Google Classroom is a very effective for used in providing information on the Civil Engineering University of Riau.


The demands of 21st-century skills are critical thinking skills and scientific literacy skills. In fact, from the results of observations and interviews conducted at MTsS Nurul Falah school, it was found that students critical thinking skills and scientific literacy skills were still low. The purpose of this study was to analyze students' critical thinking skills. students on vibration and wave material taught by the argumentation-based PBL model at MTsS Nurul Falah. This study uses a quasi-type quantitative approach experiment with the Non-Equivalent Control Group Design research design. The population used in this study were all students of class VIII. And the sample used purposive sampling techniques determined based on initial test scores when students first enter the school. Based on these considerations, class VIII-A with a total of 27 students was selected as the control class and class VIII-C with a total of 26 students was selected as the experimental class. The instrument used in this research is test questions in the form of essays. The research data were analyzed using the average test, N-gain, and independent sample t-test. The results showed that the average critical thinking value of the experimental class was in the high category and the control class was in the medium category. Based on the independent sample t-test, it was found that there was a significant difference in improving students' critical thinking skills and students' scientific literacy abilities on vibration and wave material taught using the argumentation-based PBL model at MTsS Nurul Falah.


Menorrhagia represents a major health burden to a large number of women in the UK. A range of medical and surgical treatments is now available for the condition, but each has its own advantages and limitations.


( dis ) placing neoliberalism Wendy B ROWN , Undoing the Demos. Neoliberalism's Stealth Revolution (New York, Zone Books, 2015) Undoing the Demos is a brilliant analysis and polemic, providing a lens on life as it is lived in the contemporary West that throws daily experience into stark and disturbing relief. As befits the best kind of social science, reading Undoing makes the familiar strange and freights ordinary decisions with often uncomfortable new forms of self- consciousness. The book's central argument explores the relationship of neoliberalism to the possibility of "democratic self-rule" [11]. Here I will reflect most centrally on Brown's discussion of the first term in her argument, the analysis of neoliberalism itself. Following on Foucault, the book argues that the evolution of "neoliberal reason" has remade both selves and society, turning workers into human capital and a democratic polity into a managed universe, its criteria for good governance reduced to economic calculation. This has a set of important consequences on both sides of the equation. For individuals, understood now as neither selves with interiority, laborers nor citizens, the modal relationship to self is one of investment: incurious, future oriented, individualized and, most fundamentally, calculating. On the other side, the "social" as we have known it has been disassembled. There is no community, but instead a set of self-interested individuals, purposely left to fend for themselves on the grounds of market efficiency and utility, organized by definition through competition rather than cooperation, the notion of "common good" now an oxymoron. This market structure is neither natural nor automatic. To the contrary, part of the job of the neoliberal state is to maintain sufficient inequality to support permanent competi- tion; hence rather being than a laissez-faire state, the neoliberal state is deeply involved in the market. All this undermines the logic of "solidar- ity" and so makes opposition more and more difficult and unlikely. One of the consequences of this overriding logic, Brown argues, is that it flattens substantive distinctions, creating a language that moves seamlessly across social sectors, subjecting all to the same language of "benchmarking" and "optimization" and "stakeholders." Terminology is never innocent. As the language of the economy becomes hegemonic, moving from business to university, studio and Leslie Salzinger, University of California, Berkeley [email@example.com] European Journal of Sociology, 57, 3 (2016), pp. 460–465—0003-9756/16/0000-900$07.50per art + $0.10 per page aEuropean Journal of Sociology 2016. doi: 10.1017/S0003975616000199 Downloaded from https:/www.cambridge.org/core.

Heaney has often been depicted as a writer struggling with the moral and ethical difficulties associated with his identity both as poet and as Nationalist Catholic brought up in Northern Ireland. By showing the limitations of Heaney's more self-consciously troubled and 'political' poetry (in 'North' and 'Station Island', for example), and the strengths of poems that speak more of imaginative convictions (in 'Field Work' and 'Seeing Things'), this essay argues that the poet is at his most convincing when quickened by inspirational intimations rather than tortured by perceived responsibilities


ASTRONOMYUTRECHT, THE NETHERLANDS-- Supernovas, gamma ray bursts, black holes, neutron stars, active galactic nuclei, and sites of massive matter-antimatter annihilation: The most turbulent and cataclysmic events of the universe should soon give up their secrets to Europe's International Gamma-Ray Astrophysics Laboratory, to be launched later this month. Anticipation is running so high that the first year of observing time is already oversubscribed--by a factor of 20.


Investigations were carried out in the European Russian Northeast (Komi Republic), -in the middle taiga subzone, in the (construction sand) quarry area. Formation of the soil profile within two decades after forest reclamation practices (Pinus sylvestris planting) was considered. Specifics of litter and humus horizons formation, processes of humus formation and accumulation on substrates of different granulometric composition were determined. It is shown that the rate of these processes is determined by the species composition and structure of the plant community. By the end of the second decade, up to 2.7 t·ha-1 of organic carbon accumulates in the humus-accumulative layer (0-20 cm) of sandy and sandy-loam soils, 6.3 t·ha-1 - in clay-loam soils, and 0.1 and 0.4 t·ha-1of nitrogen, respectively, accumulates there as well. The accumulation rate of Corg in the soil of the sandy and sandy-loam quarry reached 0.16, in the clay-loam quarry - 0.37 t·ha-1·year-1. The organic horizons of the forming soils demonstrate a decrease of the mass fraction of calcium, potassium, phosphorus and an increase in iron and aluminum down the profile.


Chemical grafting has been widely used to modify the surface properties of materials, especially surface energy for controlled wetting, because of the resilience of such coatings/modifications.


Plastic bottles are non-biodegradable material made up of Polyethylene Terephthalate (PET) and takes around 450 years to get decomposed. In Malaysia, near 13.2% of plastics contribute to municipal solid waste, where 2.5% is PET. To reduce the waste, interlocking bricks manufacture by waste plastic bottles are used to replace the conventional bricks that use cement and clay. The purpose of this research is to reuse plastic bottles comprised of Polyethylene Terephthalate and Polyurethane binder, by manufacturing interlocking brick that helps to reduce the waste on landfills and the pollution. The plastic bottles were shredded and grinded to a size of 0.75mm and mixed with the Polyurethane (PU) and polymer. The mixer later casted and compacted in the interlocking brick machine mould. The tests performed on the interlocking bricks were compressive strength, impact, flexural strength and thermal conductivity for obtaining the mechanical and thermal properties. The test values were then keyed into a Response Surface Modelling (RSM) to obtain the optimal PET and PU to verify reliability. Based on the results it is concluded that PET/PU of 60/40 ratio is suitable as non-load bearing masonry brick and recommended to be used as partition walls.


We consider the optimal proportional reinsurance problem for an insurer with two dependent classes of insurance business, where the two claim number processes are correlated through a common shock component. Using the technique of stochastic linear–quadratic control theory and the Hamilton–Jacobi–Bellman equation, we derive the explicit expressions for the optimal reinsurance strategies and value function, and present the verification theorem within the framework of the viscosity solution. Furthermore, we extend the results in the linear–quadratic setting to the mean–variance problem, and obtain an efficient strategy and frontier. Some numerical examples are given to show the impact of model parameters on the efficient frontier.


Introduction: Supracondylar fracture of the humerus is the most common fracture of the elbow in children and displacement is common. Main problem regarding management of early supracondylar fracture are obtaining and maintaining reduction as they commonly present in the emergency department with varying degrees of soft tissue swelling. Objective: To assess the Clinical and Radiological Outcome Type III Closed Supracondylar Fracture Of Humerus in Children treatment by percutaneous K-wires fixation. Methods: This study was carried out at the NITOR, over a period of 24 months between January 2015 to December 2016. The total number of patients were 30. All patients suffering from closed supracondylar fracture of humerus in children. Each Gartland type-III closed Supracondylar Fracture of humerus among supracondylar Fracture in children attended at emergency, outpatient department and admitted in NITOR. Results: A total number of 30 patients were enrolled in this study as per inclusion and exclusion criteria. Diagnosis of the supracondylar fracture of humerus was made by history, clinical examination and radiological evidence. The youngest patient in our series is 3 years old and the oldest is 12 years. Majority were in 5-8years. Among 30 patients mean age was 6.85 years with SD = ± 2.37 years. In the present series, maximum patients were male 22 (73.3%) and 8 (26.7%) patients were female. Male female ratio 2.75:1. Male patients were predominant in this study. The results are shown in table-I. In the present series, 19 (63.3%) with left sided supracondylar fracture of humerus and 11(36.7%) presented with right sided supacondylar fracture of humerus. The results are shown in Table-II. Out of 30 cases 15 (50%) cases gave history of fall from tree, 6(20%) cases gave history of fall from bed, 4(13.3%) cases gave history of fall during playing, 5(16.7%) cases gave history of RTA due to fall from bicycle. In the present series, postero-medial fracture was found in 18(60.0%) cases and postero-lateral fracture in 12 (40.0%) cases. Out of 30 patient's about 16 (53.3%) of the patient's was operated between (13-18) hours of receiving injury, 11 (36.7%) with in (7-12) hours and 1 (3.3%) within (0-6) hours of injury and 2(6.7%) with in (19-24) hours of injury, mean interval between injury and Operation was 8.06 ± 5.52 hours. Out of 30 patient's, 22 (73.3%) of the patients stayed in the hospital for 1 day and 8 (26.7%) of the patients stayed in the hospital for 2 days. The mean duration of hospital stay was 1.26 ± 0.45 days. In this series, among 30 Patients, 27(90.0%) had radiologically sufficient callus formation and 3(10.0%) patients had no sufficient callus formation. Functional outcome was satisfactory result (Excellent, Good and Fair) were 27(90.0%) and unsatisfactory result (poor) was 3 (10.0%). Conclusion: Finally, the result shows that in Gartland type-III closed supracondylar fracture of the humerus, closed reduction and stabilization by two lateral parallel percutaneous 'K'-wires is the good method for treatment.

24 preludes for solo piano in 4 books of 6 preludes, but published as two books (ie: books 1 and 2; books 3 and 4).

Duration: 71 minutes; pub: United Music Publishers, London
ISMN M 2244 05347.

These preludes were commissioned in 2003 by pianist, Philip Mead, through funding from the Ralph Vaughan Williams Trust, and completed in 2005. Each prelude is derived from a form of 'musical memory' of my favourite landscapes across the world but grouped under four homogeneous titles, 'Water', 'Earth', 'Air', 'Fire' based on the Four Elements. Further, the formal layout for the entire set is filtered through a working out in the cycle of major and minor keys, progressing by a 5th, starting in C major and closing in F minor.

By permission of the commissioner, Daniel Becker premiered Book 1 at a Purcell Room recital in December 2003. In 2006, Book 1 was the chosen set work for finalists in the British Contemporary Piano Competition held at the University of Surrey. Prior to that event, several of the competing pianists were given permission to give performances of it in the USA, Finland and Japan.


In the present paper, some possible parametric decay instabilities of fast magnetosonic waves (FMSW) near the second harmonic of ion cyclotron frequency have been considered in one‐ion species hydrogen plasmas. The decay channels of FMSW include an ion Bernstein wave as a high‐frequency decay wave and a low‐frequency decay wave either as an ion‐acoustic wave or kinetic Alfven wave. Applications have been pointed out to the ASDEX [Plasma Phys. Controlled Fusion 28, 235 (1986)] and ACT‐1 [Rev. Sci. Instrum. 53, 4 (1982)] toroidal devices where parametric decay instabilities of FMSW near the second harmonic of ion cyclotron frequency have been observed in the scrape‐off layer and near the edge plasma. It has been shown that the growth rate is sufficiently high at the edge and may thus contribute to the energy deposition to the edge plasma. A comparison between various decay processes has been discussed for different toroidal devices. Applications have also been pointed out to Earth's magnetospheric plasmas w...


Symmetry operations of layers periodic in two dimensions restrict the geometry the lattice according to the five two-dimensional Bravais types of lattices. In order-disorder (OD) structures, the operations relating equivalent layers generally leave invariant only a sublattice of the layers. The thus resulting restrictions can be expressed in terms of linear relations of the a2, b2 and a · b scalar products of the lattice basis vectors with rational coefficients. To characterize OD families and to check their validity, these lattice restrictions are expressed in the bases of different layers and combined. For a more familiar notation, they can be expressed in terms of the lattice parameters a, b and . Alternatively, the description of the lattice restrictions may be simplified by using centered lattices. The representation of the lattice restrictions in terms of scalar products is dependent on the chosen basis. A basis-independent classification of the lattice restrictions is outlined.


With CMOS technology scaling for miniaturization and performance improvement, analog and radio frequency integrated circuits (RFICs) are very much affected by process variations leading to performance degradation. A post-manufacturing healing mechanism with low overhead is desirable to compensate for these variations. A machine learning (ML)-assisted sensing mechanism has been proposed in this work for design of nonintrusive process variation sensor (PVS). Low-cost test signatures (TSs) extracted from these PVS are placed close to the circuit under test (CUT) and this does not load or couple to any nodes of CUT. As the TSs remain invariant with the shifts in control knobs (CKs), performance healing against process variations can be achieved with a single set of extracted TSs. A novel one-step healing approach is proposed in this work for selection of appropriate CK with the help of a neural regression model during the production test in automated test equipment (ATE). The proposed healing approach is illustrated on a current-starved voltage-controlled oscillator (CSVCO) circuit, to recover yield loss due to fabrication process variations.


Objective To investigate the antibacterial effect of room curing polymethylmethacrylate(PMMA) material adding nano-silver base inorganic antibacterial agent and to detect the changes of its mechanical property.Methods Nano-silver base inorganic antibacterial agent was added to the room curing PMMA material in the range of 0.5%-3.0% at an interval of 0.5% by ball milling to make specime.Antibacterial rates of the specimes were detected by film method.Bending strength,impact strength,and wear resistance of the specimes were respectively detected on electronic universal testing machine,impact test machine and friction and wear test machine.Results The antibacterial rates of Streptococcus mutans and Candida albicans were more than 50% when antibiotics content was 1.0%.The antibacterial rates of Streptococcus mutans and Candida albicans were more than 90% when the antibiotics content was 2.5%.The three mechanical properties were increased compared with control group when the antibacterial agents were in the range of 1.0%-1.5%.Then the three mechanical properties were decreased with the increasing of antimicrobial concentration.When the antibiotics content was 2.0%,the wear resistance had significant difference compared with control group(P0.05);when the antibiotics content was 2.5%,the bending strength and impact strength had significant difference compared with control group(P0.05).Conclusion The antibacterial effect of room curing PMMA adding nano-silver base inorganic antibacterial agent is ideal.The antibacterial rate is increased gradually with the increasing content of antibacterial agents.There is no significant effect on the mechanical properties of room curing PMMA material,but the antibacterial effects are satisfied when the content of antibacterial agents is 2.0%.


ABSTRACT High school students need more comprehensive scientific inquiry learning instruction through research ethics education. Yet, this topic is often overlooked in the science curriculum. To collect basic data to guide research ethics education for high school students, this study documents the kinds of research misconduct students commit, the contexts in which they do so, and the factors that influence such misconduct. Data were collected via questionnaires from 223 gifted high school students at science academies in Korea. The results showed that high school students engaged in the most research misconduct in experiment-based classes rather than in mentorship programmes and science fair competitions. The largest number of data fabrication and falsification instances were seen in experiment-based classes. A regression analysis on the effect of influencing factors on each research misconduct type showed that falsification and plagiarism can be reduced by increasing education and regulation and lowering desire and neglect, whereas duplicate publications can be reduced by decreasing desire and neglect levels.


A dual-polarized X-band solid-state 1-D electronic scanning "phase-tilt" weather radar (PTWR) and its scanning geometry are presented. In this architecture, the true elevation angle decreases from the nominal array tilt angle and the true azimuth angle increases from the requested azimuth as one scans off boresight. Additionally, this scanning geometry induces a canting angle effect, which can be significant especially at higher elevation tilts. The predictions of potential biases in selected polarimetric variables due to this effect are derived. For elevation angles below 10°, where polarimetric measurements are of most value, predicted biases are negligible. The PTWR was deployed in Arlington, TX, USA, for an eight-week period during Spring 2014 collecting data on a number of weather events. The direct proximity (250 m away) of a mechanically scanning magnetron-based radar, employing a dual-polarized parabolic antenna allowed for a qualitative and quantitative data comparison. We find the differences in the observations made by the two radar systems are not attributable to the aforementioned biases, but appear primarily due to differences in sampling volumes of the two radars. We also find that at high-elevation tilts, the coupling of the true elevation angle with the array-relative azimuth scan angle complicates the interpretation of features at a constant altitude such as the melting layer.

For motor fault forecast and early dignosis problems,the vibration values of the motor show the fault characteristics. The collection of a wide range of vibration frequency is realized by using the displacement sensor,velocity sensor and acceleration sensor. EIP-341 module transmits the signal to PC system or AB PLC for on-line fault detection via Ethernet network. The system has the functions of remote transmission and data storage,and the data is saved in U disk. The system can effectively prevent the happening of the motor fault and analyze the fault characteristics of motor.


Using fillers or other pigments has proved to have so much positive influence on paper making process that there has been a drastic move towards ash containing paper grades during the recent years. The advantages have to do with less expensive raw material or paper quality or both. Clay and talc are the most commonly used fillers for printing paper grades. Calcium carbonate, either natural or precipitated (PCC), is widely used in wood free fine papers. A certain amount of coating pigments come to the paper making process with coated broke. The influence of fillers on forming fabric wear on a paper machine is a complex process. The wear of a forming fabric occurs by abrading the fabric against the surface of a dewatering element. The way how the pigments take part in the abrading process depends on two factors : size distribution and form of the pigment particles and the porosity of the dewatering element surfaces. Laboratory test results concerning fabric wear under different circumstances will be presented. The tests have been performed with an Einlehner AT-1000 abrasion testing equipment. In the laboratory circumstances it is impossible to simulate the very complicated forming fabric wear process to the extent of 100%. It is, however, possible to learn the basics in the lab and utilize this information on paper machines. In practice, in addition to the properties of fillers and dewatering element materials, life time of a forming fabric depends also on other paper machine circumstances like speed former type, and number of drainage elements and their condition as well as paper machine chemistry. Possibilities to influence the filler distribution of a sheet of paper will be discussed in the latter part of the presentation. Fourdrinier-, hybridformer-, and gap former wire parts and both wood containing and wood free paper grades will be covered.


Abstract In this paper, we introduce a new spectral method based on ultraspherical polynomials for solving systems of initial value differential algebraic equations. Moreover, the suggested method is applicable for a wide range of differential equations. The method is based on a new investigation of the ultraspherical spectral differentiation matrix to approximate the differential expressions in equations. The produced equations lead to algebraic systems and are converted to nonlinear programming. Numerical examples illustrate the robustness, accuracy, and efficiency of the proposed method.


Congenital nasolacrimal duct obstruction (CNLDO) is the most common abnormality of infants' lacrimal apparatus, occurring in 2% to 6%.1 Although controversy continues to exist, most studies have shown spontaneous remittance in 80% to 90% of affected infants by 12 months of age.1 If symptoms of CNLDO persist to 13 months of age, most pediatric ophthalmologists would proceed to a probing procedure. If symptoms of CNLDO are not resolved after the first probing, then whether to repeat the probing procedure or proceed directly to a nasolacrimal intubation is determined by the pediatric ophthalmologist's previous training and experience. A second probing, if necessary, is often successful for many pediatric ophthalmologists and can be performed with minimal anesthesia. Intubation is a longer procedure and usually requires general intubation and anesthesia. The study by Napier et al. in this issue found that if initial probing is not successful, nasolacrimal intubation had a significantly higher success rate than repeat probing. However, there were several limitations pointed out by the authors: the numbers in the analysis of secondary surgeries were relatively small, surgery was performed by many pediatric ophthalmologists, and the data were collected retrospectively. Further prospective studies are necessary to resolve the issue of repeat procedures for CNLDO.

A murine line with a haploinsufficiency in SCN5A has been used to model human Brugada syndrome: a disease causing sudden cardiac death due to lethal ventricular arrhythmias. We explored the effects of cholinergic tone on electrophysiological parameters in wild type and genetically modified, heterozygous, Scn5a+/- knockout mice. Scn5a+/-, ventricular slices showed longer refractory periods than wild-type both at baseline (Scn5a+/- 79±4 vs WT 63±4 ms, p <0.001) and during isoprenaline challenge. Scn5a+/- hearts also showed lower conduction velocities than did WT at baseline (0.27±0.04 vs 0.47±0.11 m/s, p=0.01) and blunted responses to isoprenaline challenge. Carbachol exerted limited effects but reversed the effects of isoprenaline with co-application. Scn5a+/- mice showed a reduction in conduction reserve in that isoprenaline no longer increased conduction velocity and this was not antagonised by muscarinic agonists.


Treatment ofRu 11 (porp)L 2complexes with FIX acids in C6H yields the corresponding paramagnetic Ru"Qorp)X 2complexes, where porp = the 2, 3, 7, 8, 12, 13, 17, 18octaethylporphyrin dianion(OEP), L= pyridine(py), X Cl; and porp = the 5, 10, 15, 20tetramesitylporphynn dianion(TMP), L = CH 3N, X= Cl or Br. The 3 day reactions ( at room temperature) proceed via the paramagnetic Ru(porp)X(L) intermediates, as demonstrated by isolation of Ru(OEP)Cl(py) and Ru(TMP)Br(CH 3CN). The Ru(OEP)Cl(py) complex was also produced in situ by the reaction of Ru(OEP)C1 2with Ru(OEP)py 2.Reduction of the dihalo species with anhydrous ammonia yields the paramagnetic Ru(porp)X(NH 3species. Cyclic voltammograms of the Ru(porp)X 2complexes (where porp = OEP, X = Cl; porp = TPP (TPP 5, 10, 15, 20-tetraphenylporphyrin dianion), X = Cl; porp = TMP, X Br and Cl) show reversible Ru"(porp) /RuT(porp) couples in the range of 1.22 to 1.35 V, reversible Ru(IV)fRu(ffl) couples from 0.41 to 0.64 V, and a third irreversible response (tentatively assigned to the Ru(jorp)/Ru(porp) couples) in the range of -0. 82 to -0.56 V vs. Ag/AgCI. The reversible Ru"(porp)/Ru"(porp) couples of Ru(OEP)Cl(NH 3)and Ru(TMP)Cl(N11 3)were measured at 1.31 and 1.45 V vs. AgIAgC1, respectively, while the reversible Ru(IV)/Ru(ffl) couples were found at 0.74 and 0.85 V. Reversible signals (tentatively assigned as the Ru(ffl)/Ru(ll) couples) were also observed at -0.51 and -0.42 V vs. AgIAgC1 for the OEP and TIVIP complexes, respectively. The diamagnetic Ru(TMP)R 2complexes (R = Me, Ph) were isolated from the reaction


Background: Multiauthorship in scientific papers is now the norm. The oncology, as an extremely complex and interdiscipline science, is particularly prominent in this regard. In order to evaluate the prevalence of single- and multiauthored papers in national and international oncologic journals, a simple bibliometric analysis was undertaken. Materials and methods: Three scientific journals that publish articles from all fields of clinical and experimental oncology - Archive of Oncology (Arch Oncol), Journal of Balkan Union of Oncology (J BUOn), and Annals of Oncology (Ann Oncol) - were analyzed in regard to the number of original papers per issue, and the frequency of single- and multiauthorship in original papers. Results: The Arch Oncol, J BUOn and Ann Oncol had published 5.5, 10.2 and 7.8 articles per issue, respectively. The single-author articles make 10% of all original papers in Arch Oncol, 5% in J BUOn, and less than 1% in Ann Oncol. The high number of coauthors (~10) had signed 20.6% of articles published in Ann Oncol and 1.5% in J BUOn; no such article had appeared in Arch Oncol. The mean number of coauthors in average original paper published in Arch Oncol, J BUOn and Ann Oncol was 4.3, 4.7, and 8.3, respectively. Conclusion: The two first journals are similar in regard to most bibliometric parameters; they differ significantly from Ann Oncol in these aspects.


An affine real-valued algebraic curve is called an a ne M -curve if it has the maximum possible number of connected components allowed by the Harnack inequality. In particular, an affine M -sextic has 16 connected components, 10 of which are ovals and the remaining 6 can be obtained from the 11th projectivisation oval by removing infinitely distant points. In the present note we extend the isotopic classification of affine M -sextics initiated in [1]–[5] and present the details of a realization of the isotopy type A3(0,5,5) (see Fig. 1, where L is an infinitely distant straight line), which was erroneously declared prohibited in [3]. The result and the idea of the proof were announced in [5], §2.


Abstract This study documents the diet of Mexican free-tailed bats (Tadarida brasiliensis mexicana) at Carlsbad Cavern, Carlsbad Caverns National Park, Eddy County, New Mexico, and provides information on seasonal variation in food habits of this species throughout its summer residence. Diet was determined from 1,303 fecal samples. Eleven orders and 38 families of insects, unidentified insects, 2 orders of Arachnida (Araneae and Acari), bat hair, and mist net were consumed, with Lepidoptera (moths) and Coleoptera (beetles) occurring at greatest percentage volumes and percentage frequencies in the diet. Diet varied significantly throughout the season. Twenty-two food categories exhibited statistically significant variation among sampling sessions. Amounts of Coleoptera, Lepidoptera, Formicidae, Psyllidae, Hymenoptera, and Diptera consumed showed the greatest differences among sampling sessions.


Background: Indonesia faces serious challenges from a double burden disease caused by changes in people's lifestyles. Since 2010, Non-communicable diseases (NCDs) include hypertension, stroke, heart disease, and diabetes have taken up a growing share of health-care resources. The coronavirus disease epidemic of 2019 (COVID 19) caused by the new coronavirus SARS-CoV2 is the most serious global health issue. Patients with COVID-19 had more hypertension, diabetes, and other cardiovascular diseases, which all require routine health monitoring. Health monitoring will greatly develop along with the development of technology and information 4.0. This includes nursing services in the future that will take advantage of developments in information technology.

Since 1991 privatisation, contracting out and market testing have become central concerns as the process of reform in the civil service bas entered a new and more radical phase. Following the publication in 1991 of the Government's Citizen's Charter and the White Paper Competin& for Quality, the level of contracting out and market testing undertaken in central government departments and agencies bas increased dramatically. The publication in March 1994 of The Citizen's Charter Second Report: 1994, which outlines the progress of the Competing for Oualitv and Citizen's Charter initiatives, provides an appropriate time to evaluate the developments than have taken place so far. Given that publicly available information presented in this and other government reports is somewhat fragmentary in character, analysing recent developments is a far from simple task.


Background: The aim of the study was to evaluate the clinical efficacy of demineralised freeze dried bone allograft (DFDBA) and platelet rich fibrin (PRF) membrane in immediate implant placement into debrided infected mandibular molar sockets.

Methods: A clinical trial was conducted on 15 adult patients requiring tooth extraction and replacement with endosseous implants. Atraumatic tooth extraction was followed by thorough debridement of the socket prior to implant placement. Demineralized freeze dried bone allograft and PRF membranes were used for guided bone regeneration. Pain, signs of infection, vertical bone height measurements (IS-BIC) and stability of implants (torque values) were assessed using paired t test, analysis of variance (ANOVA) and Chi-square test.

Results: Statistically significant reduction in pain from immediate post-operative (post-op) day to 1st post-op day, 7th post-op day to 4 months post-op (p=0.006) was seen. Infection was present preoperatively and absent post-op 1st day, 7th day and 4 month in all the subjects. The mean IS-BIC was 2.30±2.27 mm post-op and 0.75±0.74 mm at 4 months. Average height gain on mesial and distal side was 1.55 mm (p=0.009).

Conclusions: With proper pre-op and post-op care, immediate implant placement along with DFDBA and PRF membrane in teeth exhibiting periapical pathology, is a cost effective, time saving and reliable treatment option.


E2F transcription factors are important elements in cell cycle regulatory network that regulate cell proliferation, differentiation and apoptosis, consequently involved in many physiological and pathological processes. The biological function of E2Fs has been widely investigated in mammals. The recent identified atypical E2F family members of E2F7 and E2F8 in mammals develop a new insight of cellular E2Fs function. Compared to the typical E2Fs, atypical E2F proteins have the duplication of DNA-binding domain and regulate gene expression independent of dimerization partner protein. Nuclear localized atypical E2F proteins act as transcription inhibitory factors on typical E2F-driven target genes and modulate cell cycle progression, and play a crucial role in cell size determination, polyploidization, cell proliferation, differentiation and apoptosis. The establishment and improvement of knockout mice model make it possible for us to study the physiological function of atypical E2Fs in specific tissues and organs. Atypical E2Fs function in regulating embryonic development, angiogenesis and hematopoiesis. In addition, change of the expression levels of typical E2Fs and atypical E2Fs correlates with tumorigenesis in humans. This review summarized the latest advances in the studies on expression, regulation and function of atypical E2F transcription factors in physiological and pathological processes.

Post traumatic posterior urethral strictures were managed by trans-symphyseal urethroplasty in 11 male patients of pediatric age group. The aim of the study was to evaluate the results of the technique in patients who underwent multiple unsuccessful procedures in the past. Two(18.2%) patients were 3-5 years old, 3 (27.3%) were between 6 and 8 years, 1 (9.1 %)was 10 years old whereas 5(45.5%) were 12-14 years of age. The length of the strictures varied from 1-3cm. Repair was performed after excising the stricture and anastomosing the spatulated urethral ends with interrupted sutures of 5/0 vicryl over a Foley`s catheter. Post operative follow up showed incontinence in 1(9.1%) case and prolonged urinary tract infection in 4(36.4%) cases. Postoperative stricture was not noted in only one of them at I year follow up. The authors recommend that trans-symphyseal urethroplasty is a satisfactory procedure for the treatment of posterior urethral strictures in children as it provides excellent approach and visualization with minimal post operative complications.


Introduction: Diabetes mellitus is a common pathological condition of the present times, with a higher prevalence rate in developing countries. It has a marked impact on the quality of life due to the acute and long-term complications secondary to the involvement of micro and macro vasculature with the progression of the natural history of disease. The Doppler ultrasound is non-invasive and can be used as a means of evaluating vascular complications in diabetics. Hence, the aim of the present study was to determine the frequency, level and flow patterns in lower limb arterial insufficiency among diabetic patients with the help of Doppler ultrasound study. Materials and Methods: The present prospective study was done in December 2011 to December 2012 on 100 patients admitted in the Krishna institute of medical sciences, Karad. Adult diabetic patients (aged 18 years or above) irrespective of type of diabetes and gender with suspected peripheral vascular insufficiency or complaints of numbness, discoloration of periphery or ulceration were taken in this study. Results: The most common artery involvement was found to be dorsapaedalis artery in 26% of the cases followed by proximal femoral and distal femoral in 18% of the cases whereas there were 12% cases with popliteal artery and distal artery branches involvement. The most common site of lesion involved was proximal femoral artery and dorsapaedalis artery seen in 26% of the cases (both) whereas distal femoral artery (DFA) was found in 10% of the cases, poplitial artery (PA) in 18% of the cases followed by posterior tibial artery (PTA) and anterior tibial artery (ATA) in 8% and 12% of the cases respectively. Conclusion: Peripheral vascular insufficiency was a significant finding in patients having diabetes for 1-10 years. The dorsalispaedis artery was the commonest site of involvement. The normal Doppler study virtually rules out a haemodynamically significant lesion and helps to prevent unnecessary intervention.
