This paper applies what is already known about the aspiration efficiency of blunt aerosol samplers at large angles to the interesting case of sampling under «orientation-averaged» conditions. This is particularly relevant to practical aerosol sampling in workplaces and the atmospheric environment. The resultant semiempirical model of aspiration efficiency contains a number of coefficients which are fitted by nonlinear regression to data sets for the human head and for two rotating-head inhalable aerosol samplers (a 3 L/min sampler intended for applications in workplaces and a 70 L/min sampler intended for particle sampling in the ambient atmosphere). Agreement for all three data sets (with 88, 64, and 37 records respectively) is generally good, with an overall R corr 2 of 68%. Such semiempirical models can be useful for predicting and interpreting sampler performance until practical versions of more rigorous mathematical and numerical models become available


Modulated by selective predation pressure, defensive behaviours exhibited by anurans can be: (1) passive (e.g. colouring, chemical and mechanical defences) or (2) active and postural (this category includes actions such as the choice of a site for reproductive activities to the execution of behaviours in the presence of a potential predator) (Duellman and Trueb, 1986; Sazima and Caramaschi, 1986; Wells, 2007). Thanatosis, crouching, and deimatic behaviour are some of the most common postural defences in many species of frogs (Duellman and Trueb, 1986; Toledo, Sazima and Haddad, 2010) which minimize the chances of attack by predators and increase the likelihood of not being attacked in the future (Gallup et al., 1971; Gerald, 2007). The direction of the stimulus, as well as extrinsic abiotic factors and intrinsic physiological factors, may be responsible for the expression or intensity of thanatosis (Gomes, Bevier and Navas, 2002). Despite the potential importance for adult survival and, ultimately, for maintaining the dynamics of an anuran population, there is still little information about the influences of extrinsic factors on the execution of death feigning behaviour, as well as its frequency and duration. In this study we describe thanatosis of Physalaemus kroyeri, a species which has a restricted geographical distribution within the states of Bahia, Minas Gerais, Piauí, and Paraiba, Brazil and is associated with open formations of the Cerrado and Caatinga (Nascimento, Caramaschi and Cruz, 2005; Frost, 2011). We also evaluated whether morphometric measurements (SVL) and abiotic conditions affected the onset of thanatosis.


South Korea's nitrogen (N) balance is the highest among OECD countries. However, this figure is likely to be overestimated. Besides, there is a lack of scientific logic to persuade stakeholders (i.e., fertilizer company, livestock farmer) when these numbers are used as a basis for the N reduction policy. N balance is the residual value after subtracting the amount of N flowing out of the specific boundary from the amount of N entering the boundary. The boundaries of N balance are divided into farm budget, soil budget, and land budget. OECD uses a land budget for N balance calculation. The N inputs consist of mineral fertilizers, organic fertilizers, livestock manure, crop residues, seed and planting materials, biological N fixation, and atmospheric deposition. The N content in the crops produced corresponds to the N output. The N balance method proposed by the OECD is based on a grazing farming system. This method derives from the agricultural environment in which livestock manure is directly deposited into farmland. However, most of the livestock manure in South Korea is not used directly in farmland but is converted to compost and liquid fertilizer. N loss occurs during composting and liquid fertilizer production, which means that the amount of N loaded on the actual soil can be significantly reduced. Another concern related to N from livestock manure is the source of the N content in the crop. N absorbed by crops is not distinguished from livestock manure N, chemical fertilizer N, or soil N. If policymakers intend to reduce N by limiting mineral fertilizers or livestock manure, the N use efficiency of crops based on N sources will play an important role. Therefore, this paper discusses two uncertainties (N loss rate and crop N uptake) related to N from livestock manure and suggests ways to improve N balance.

What determines product variety in vertically related markets? We study a model in which rival manufacturers bid for distribution at retailers who compete for final consumers. Product variety comes at the cost of fierce retail competition, because rival manufacturers are unable to internalize all contracting externalities. Non-inferior brands, therefore, might not get distribution in equilibrium even though consumers have a strict preference for variety. We illustrate how the problem of exclusion disappears under an industry-wide ban on slotting allowances or with an upstream horizontal merger.


In this paper it is discussed a new method to transform a closed and possibly unconnected polyline into a plane polygon represented as a BSP tree In particular it is shown that each such polygon can be expressed as the Boolean XOR of unbounded quadrilateral stripes bijectively associated to the polyline edges Such a representation has a space complexity of O n where n is the number of polygon edges A set of quasi disjoint convex cells which partitionate the polygon is then generated by traversing the BSP tree This method seems interesting since a it allows for independent processing of edges and it is hence easily parallelizable and b a generalization of the presented approach to n dimensional polyhedra is quite straightforward


Depleting natural resources and large amounts of waste increase the environmental pressure affecting the economy and humans. Emerging sustainability challenges require new behavioural patterns from both the business and consumers. Responding to these constraints, the circular economy is promoted as a new way towards a sustainable future. While the circular economy provides new principles for improving resource efficiency and reducing waste, most of companies run traditional business models with the perception that competitive advantages can be achieved by increasing production. Instead circular business models seek for increase of profitability and efficiency through adapting various business model innovations. However, their adoption process and results are unclear for many industries highlighting the topicality of this article. This research shows that milk processing companies lack an experience and understanding of benefits and challenges of circular business models. In milk processing, the whey is considered as problematic waste or the production leftover, which requires new treatment. The research provides analyses of the whey recycling circular business models that ensured new revenue streams, higher profitability, return on assets and competitive advantages for milk processing companies. The COVID19 pandemia increases the importance of this issue as the dairy industry due to livestock requirements shall ensure business continuity despite a crises or other risks that slowdown the business.


Nowadays, Internet of Things (IoT) devices and applications are largely and successfully used in almost every human activity. Together with smart cities and industrial IoT, one of the top three sectors with a notable estimated growth in the years to come is Health Internet of Things (HIoT). Due to obvious benefits as faster response and better functioning of medical devices, remote diagnosis and treatment, continuous monitoring of patients with implanted devices, better support for clinical decisions, and lower costs, IoT is becoming increasingly relevant in the context of health-care and medical applications. In order to provide these advantages, interconnected patient and hospital IoT devices collect, transmit and process significant amounts of sensitive data. Problems as the lack of transparency in the use of data and contextual metadata, weak security methods implemented in medical devices, probability of human errors and software or hardware malfunctions, autonomous, ambiguous and unpredictable behaviour of the interconnected things expose both the health institutions and their clients to significant risks, from harming the privacy of patients to actual health damage. In this spirit, the paper reviews the ethical and security-related concerns in health-IoT and suggests solutions to present and future challenges.


The mainstream Islamic community in Malaysia has already began to be exposed by the practice of sanad talaqqī in the context of quranic studies. Nowadays, many people struggled to obtain the Quranic sanad talaqqī. This system is a tradition that has been emphasized by the qurrā' and began to spread in Malaysia. It is widely known that the Quran has been inherited to and by every generation through reading method known as talaqqī mushāfaḥah. Among the sanad that are spread in Malaysia are the sanad talaqqī 30 juzu' and the sanad talaqqī al-Fātiḥah. However, society are still less known and understood about the concept of Quranic sanad talaqqī. Therefore, research needs to be done to introduce to the society the practice of the inheritance of Quranic sanad talaqqī in Malaysia. This study will focus on the graduation practice of sanad talaqqī al-Fātiḥah. Data of the study were collected through library documents and sanad talaqqī al-Fātiḥah certificates, while the data analysis method was descriptive. Findings show that there is activity in the graduation of sanad talaqqī al-Fātiḥah in Malaysia but it is not yet widespread. The criteria found on the sanad certificates were also analyzed as a research finding. The implications of this study are important to guide the society in order to build a proper perception towards the graduation of sanad talaqqī al-Fātiḥah. The society needs to be introduced to the practice of Quranic sanad talaqqī in order to produce many individuals who are able to read the Quran fluently and eloquently.


The performance of a scintillating ber (2mm diameter) position sensitive detector (4:8 4:8 cm 2 active area) for the single bremstrahlung luminosity monitor (LMPSD) at the VEPP-2M electron-positron collider at the Budker Institute of Nuclear Physics in Novosibirsk, Russia is described. Custom electronics is triggered by coincident hits in the X and Y planes of 24 bers each, and reduces the 64 channel photomultiplier signals (one for each 25 cm long ber) to a 10 bit (X,Y) address. Hits are accumulated (10 kHz) in memory and display (few Hz) the VEPP-2M collision vertex. Fitting the strongly peaked distribution (3-4 mm at 1.6m from the collision vertex of VEPP-2M) to the expected QED angular distribution yields a background in agreement with an independent determination of the VEPP-2M luminosity.


This edition of the book has been extensively revised with an additional 80 pages also having been added. The first edition received many favourable reviews and this edition will also become essential reading for anyone concerned with how Scotland's environment is managed. It is a modern and authoritative view of Scotland's countryside as a cultural landscape. The book consists of 14 chapters aggregated into five sections: the nature and control of the land; the pieces of the jigsaw; interactions and controversies; thinking and deciding about the environment; and conclusion. There are 55 pages of references dating from 1949 (Aldo Leopold's meditations on a land ethic in Sand County Almanac) to 2008 with many having been added since the first edition. While this comprehensive list of modern and important references is excellent, it would have been good to introduce readers to some of the older literature, for example Frank Fraser Darling's seminal West Highland Survey from 1955. Inevitably, there is insufficient space to fully develop arguments. From that point of view the individual chapters would be excellent starting points for a tutorial or other discussion. However, themes are often picked up in more than one chapter and, although the author has cross-referenced some of these links, the book really needs to be read as a whole to avoid missing important detail. Inevitably there are topics that have had to have been missed out. The author no doubt considered including the coastal and marine environment but recognised that the additional issues associated with the sea would require a book in its own right. Nevertheless, it is difficult to understand land in the north and west without considering the influence of the sea. The Central Scotland Forest Initiative is briefly referred to and it would have been informative to have included a wider discussion of urban and peri-urban environments. Although clearly not 'natural' these often now include healthy functioning ecosystems that play an important part in conserving habitats and wildlife, particularly now that many urban rivers have been returned to good ecological status. There are inevitably dangers of over-generalisation, and the ecological fallacy, where all members of a group are assumed to have the average characteristics of the group as a whole, always lurks in the background of discussions about land. Surveys have shown the richness of variation in farmers' motivations, profitability, productivity and environmental impact, some of which is hinted at here. Sometimes a little more detail or interpretation would be helpful. For example, although the 17% woodland cover of Scotland may appear relatively low, there are considerable areas of land inappropriate for planting due to altitude, exposure or the presence of blanket bog, and the proportion of potentially plantable land is much higher. There are also statements which, though true, are misleading. For example, the author correctly notes the increased fertiliser application since the 1950s but neglects to mention that phosphate applications have fallen by half since 1983 and that there is a continued decline in nitrogen applications.

This paper proposes a novel semi-supervised regression model with co-training algorithm based on support vector machines, which retrieves water quality variables from SPOT5 remote sensing data. Nonlinear relationship between water quality variables and SPOT5 spectrum are described by two support vector regression (SVR) models. Semi-supervised co-training algorithm for the two SVR models is established. The method is used for retrieving four representative water quality variables of the Weihe River in Shaanxi Province, China. The results show that the new method has better performance than the statistical regression method. Through integrating two SVR models and using unlabeled samples, an operational method when paired samples are limited is obtained. Combining techniques of machine learning and remote sensing, it provides an effective approach for remote sensing water quality retrieving.


Dear Editor, Pustulotic arthroosteitis (PAO) is a chronic and intractable complication of palmoplantar pustulosis (PPP).1 PAO patients are often treated by dermatologists or rheumatologists. Since standard methods for its treatment are not well established, treatment strategies may vary depending on the specialties of the physicians. Thus, we aimed to elucidate the differences in the management of PAO between dermatologists and rheumatologists as the first step of mutual understanding. This was a singlecenter, noninterventional, retrospective study analyzing medical records of patients with PAO who visited the Department of Dermatology or Rheumatology at Nihon University Itabashi Hospital between December 2017 and September 2018. The diagnosis of PPP and PAO was made by boardcertified dermatologists or rheumatologists. This study was approved by the institutional review board (RK20090812). Statistical analyses were performed using JMP version 12 software (SAS Institute). p < 0.05 was considered significant. Eighteen patients (83.3% female, 60.9 ± 10.7 years old) were enrolled from the dermatology clinic and seven patients (43.9% female, 57.1 ± 11.6 years old) from the rheumatology clinic (Table 1). Basic patients' backgrounds such as sex, disease duration, and type of arthropathy were comparable between the two groups. There were considerable differences in the treatment (Table 1). Although tumor necrosis factor inhibitors and methotrexate were similarly used in both departments, cyclosporin was solely used at the dermatology clinic (94.4% vs 0%; p < 0.001). In contrast, sulfasalazine was prescribed only by rheumatologists (0% vs 57.1%; p = 0.003). In addition, use of nonsteroidal antiinflammatory drugs was more commonly observed in patients visiting rheumatologists than those visiting dermatologists (50.0% vs 100.0%; p = 0.03). Irrespective of such treatment discrepancies, there were no significant differences in the clinical and radiological improvement between both arms (Table 1). Two patients visiting the rheumatology clinic experienced septic arthritis and lymphoproliferative disorder respectively, which resulted in treatment discontinuation (Table 1). Cyclosporin treatment for PAO was preferred by dermatologists rather than rheumatologists, whereas the opposite was true for sulfasalazine therapy. This difference may reflect experiences in the management of psoriasis and rheumatoid arthritis for dermatologists and rheumatologists, respectively. However, treatment variance was not significantly linked to patient outcome. Cyclosporin showed effectiveness for PAO in a small study.2 Although the effectiveness of sulfasalazine for PAO is still to be examined, our data might suggest the possibility of its usefulness for this condition. However, there were several limitations of this study including small sample size, short observation period, limited number of involved physicians, inconsistent methods of outcome evaluation, and insufficient assessment of focal infections and disease severity of PPP and PAO. These points may have influenced the results. Further studies are needed to determine the significance and positioning of "dermatologisttype" and "rheumatologisttype" treatment approaches in the management of PAO for the better collaboration among the departments.


The electronic sign at the Minneapolis-St. Paul airport was flashing "Orange Alert" as a dozen Buddhist monks arrived in their burnt orange robes from around the country for three days of dialogue on celibacy with a similar number of Catholic monastics come together from various monasteries at St. John's Abbey in Collegeville, Minnesota. As he opened the October 26-29, 2006, meeting, Rev. William Skudlarek, executive director of Monastic Interreligious Dialogue (MID), said, "You (Buddhists) have been at this for some five-to-seven hundred years longer than we have. We have something to learn." This was the second Monks in the West interreligious dialogue. The first took place in 2004 at the City of Ten Thousand Buddhas in northern California. On the Catholic side, the participants came from the Benedictine, Cistercian, and Camaldolese monasteries. On the Buddhist side, they came from the Theravada, Mahayana, and Tibetan traditions. Through the event, participants began the day with an hour of quiet sitting in meditation and joined the monastic community at St. John's for their rhythm of daily prayer. The first session dealt with theory, the "why" of celibacy. Buddhist participants explained that their teachings focus on seeing how suffering is created and cured. Attachments give rise to suffering, so advancement in the spiritual life requires letting go of one's attachments. Attachment to desires, among which are sexual desires, is a hindrance to spiritual progress. "Raging desire takes away choice, freedom," said Rev. Kusala Bhikshu, a Buddhist chaplain at UCLA, in his opening presentation. "The senses must be controlled in order to be free." Brother Gregory Perron from St. Procopius monastery in Indiana spoke of how monastic life demands a profound understanding and acceptance of solitude. "Celibacy is a tool," offered Perron, "a skillful means like intentional simplicity of life, by which our heart is burrowed out and the core of our being laid bare. By embracing it, the monk accepts the aloneness that characterizes every human being." In response to Buddhist reflections on the illusory nature of the body, Catholic participants pointed out Christianity's remarkably positive evaluation of the

This text reflects on the specificity of the young adult literary subsystem, problematizing the question of the elision of frontiers in relation to the adult literary system, from the analysis of a set of contemporary novels, aimed at different readers, published in Portugal between 2011 and 2013, that present adolescent narrators and deal with issues of identity construction. The selected novels, written by different contemporary novelists, Jose Eduardo Agualusa, Dulce Maria Cardoso and Manuel Jorge Marmelo, have in common, in addition to the narrative perspective centred on adolescence, the reflection on growing processes which take place in very challenging existential conditions, testing the narrators. Besides being coming-of-age stories, the selected novels also present a critical perspective on the adult world.


On the basis of available experimental data of the state diagram Li-Ga system, thermodynamic simulation of liquidus in the system Li-Ga has been carried out with using of the model of subregular solutions. From the results of calculations energy parameters of mixture of system components in a melt have been determined and the temperature dependences of constants of melting of chemical compounds in the system have been found out. The developed calculated liquidus line of the system corresponds to the available experimental data of the state diagram. The results of the research allow determining the dependence of activities of components in melt on atomic per cent and can be used while growing monocrystals of gallium nitride in lithium flux.


Abstract Massive information from the West flows freely into developing countries through a wide variety of media. This one-way flow of information is both to the advantage and disadvantage of the recipients. On one hand, the import of books and journals provides information in all fields. But on the other hand, they lead to the subjugation of Third World countries to Western cultural influences. Information and the media are tools used by the dominant information and technology centres of power to manufacture consent and shape the contours of public ideology for their own interests. As the flow of information across national and cultural boundaries intensifies, many Third World countries suffer political, economic, psychological, technological and cultural pressure exerted by this information imperialism. Theoretically, with technological advances that are fast becoming available and more affordable, developing countries can certainly become more advantageously integrated into the information highway. This is, however, not easy. Though they may have gained independence and though they may have shed many colonial practices and undergone tremendous changes, many countries in the Third World are still stuck with their former colonial masters, thanks to a cultural domination exercised through information flow.


We report the stability and solubility of the FeAlO3 component in bridgmanite based on phase relations in the system MgSiO3‐FeAlO3 at 27 GPa and 2000 K using a multi‐anvil apparatus combined with in situ synchrotron X‐ray diffraction measurements. The results demonstrate that the FeAlO3 component dominates Fe3+ and Al3+ substitution in bridgmanite, although trace amounts of oxygen‐ and Mg‐site vacancy components are also present. Bridgmanite with more than 40 mol% FeAlO3 transforms into the LiNbO3‐type phase upon decompression. The FeAlO3 end‐member decomposes into corundum and hematite and does not form single‐phase bridgmanite. We determined the maximum solubility of the FeAlO3 component in bridgmanite at 27 GPa and 2000 K to be 67 mol%, which is significantly higher than previously reported values (25–36 mol%). We determined the partial molar volume (27.9 mol/cm3) and bulk modulus (197 GPa) of hypothetical FeAlO3 bridgmanite, which are significantly higher and lower than those of AlAlO3 and FeSiO3 bridgmanite, respectively. The non‐ideality of MgSiO3‐FeAlO3 solid solution (W = 13 kJ/mol, where W is the interaction parameter) is significantly larger than that for MgSiO3‐AlAlO3 (5 kJ/mol) and MgSiO3‐FeSiO3 (3 kJ/mol) solid solutions. The rapid decrease in abundance of the MgAlO2.5 component in bridgmanite with increasing pressure is enhanced by the presence of the FeAlO3 component. The FeAlO3 content in pyrolite and mid‐ocean ridge basalt is far below its solubility limit in bridgmanite and provides new insight into the mineralogy of the lower mantle.


Purpose: This study was conducted to determine if phonological production proficiency in bilingual Spanish-English preschoolers could be predicted by their language environment, language ability, and phonological production proficiency in their other language. Method: Participants were 199 Latino children and their families. Children ranged in age from 36 – 77 months. Children"s phonological production ability in English and Spanish was assessed using the Bilingual Phonological Assessment (BiPA; Miccio & Hammer, 2006). Responses were transcribed and analyzed to determine Percentage of Consonants Correct-Revised (PCC-R; Shriberg, Austin, Lewis, McSweeney, & Wilson, 1997), Phonological Mean Length of Utterance (PMLU; Ingram, 2002) and Percent of Whole Word Proximity (PWP; Ingram, 2002). Language abilities were assessed using the Picture Vocabulary and Story Recall subtests of the WoodcockMun oz Language Survey-Revised (Woodcock, Mun oz-Sandoval, Ruef, & Alvaradeo, 2005). Information regarding the children"s exposure to and use of English and Spanish was collected by means of a parent survey. Hierarchical regression analyses were employed to determine the degree to which language abilities, exposure to and use of each language, and phonological production proficiency in the other language were able to predict children"s phonological production proficiency in English and Spanish. Results: A large portion of the variance in phonological production proficiency scores in English (R 2 = .62 -.69) was predicted by the language the mothers used when speaking to their children, children"s English vocabulary scores, and children"s


JPEG XS is a standardization activity conducted by the Joint Photographic Experts Group (JPEG), formally known as ISO/IEC SC29 WG1 group that aims at standardizing a low-latency, lightweight and visually lossless video compression scheme. This codec is intended to be used in applications where image sequences would otherwise be transmitted or stored in uncompressed form, such as in live production (through SDI or IP transport), display links, or frame buffers. Support for compression ratios ranging from 2:1 to 6:1 allows significant bandwidth and power reduction for signal propagation. This paper describes the objective quality assessment procedures conducted as part of the JPEG XS standardization activity. Firstly, this paper discusses the objective part of the experiments that led to the technology selection during the 73th WG1 meeting in late 2016. This assessment consists of PSNR measurements after a single and multiple compression decompression cycles at various compression ratios. After this assessment phase, two proposals among the six responses to the CfP were selected and merged to form the first JPEG XS test model (XSM). Later, this paper describes the core experiments (CEs) conducted so far on the XSM. These experiments are intended to evaluate its performance in more challenging scenarios, such as insertion of picture overlays, robustness to frame editing, assess the impact of the different algorithmic choices, and also to measure the XSM performance using the HDR VDP metric.


When allegations surfaced last year that American state secrets had been reaching China by various routes, the US Congress decided to expand the government's control of technology. An amendment that was passed without debate transferred control of certain research activities that had been regulated by the Department of Commerce to the State Department. That amendment has had serious repercussions for academics who rely on satellites for their research.


We have analyzed two polymorphic regions of the apo B gene (5{prime} (CA)n microsatellite and insertion/deletion polymorphisms) in a random control sample and coronary heart disease (CHD) patients from Moscow. For this purpose we have used PCR technique followed by high-resolution PAGE. In the control sample only 3 different allelic variants of the 5{prime} minisatellite existed with 14 (frequency 70,7%), 15 (26,8%) and 16 (2.5%) CA repeats. In the patient`s group, allelic variants were also found with 13 CA repeats, but the frequency was very low (2.5%). However, we did not reveal any significant differences in allele and genotype distributions of insertion/deletion polymorphisms in the control group and the group of CHD patients (insertion frequency 67.9% and 62.5%, respectively).

The paper reviews the current state and the development strategies of telecommunications in Hungary. Telephone systems are predominantly analog, with a relatively low main-line penetration ratio (14.5% by the end of 1993) and several years waiting time. Advanced telecommunications services are scarcely established. However, the significance of telecommunications has been recognized, therefore intensive development and modernization plans were formed, the legislative environment has been liberalized, the state-owned network operator has been partly privatized, and the full restructuring of the telecommunication sector is in process. Over the last several years, Hungary focused on the basic network infrastructure and fixed telephone service, but mobile telephony was also urgently required for the rapid satisfaction of business needs. The need to join Europe accelerates the pace of digitalization and the introduction of new telecommunication services, as well as the establishment of international cooperation to harmonize the expansion of international links. The paper summarizes the general features and development goals for this decade. >


Commercial vehicles play an important role in the movement of goods in urban areas. Although they account 10 – 15 percent of the total daily urban traffic (Hunt and Stefan, 2007), they have a higher impact on the performance of the transportation system. More specifically commercial vehicles on average have significantly larger gross vehicle weight (GVW), and as such contribute to the deterioration of pavement and air quality. The spatial distribution of commercial vehicles, as in the case of private vehicles, is a key determinant of the level of traffic volume that can be observed on the road network. To date, analysis to analyze the spatial location of commercial vehicles is limited. Most of the existing efforts have been focused on private vehicles instead. Identifying the factors that explain the prevalence of specific types of urban commercial vehicles at a given location in the city could help transportation modelers to devise effective travel demand models. In this paper the determinants which lead to the prevalence of a specific type of commercial vehicles (as derived from the GVW classes) in a given zone are investigated. A multinomial logit (MNL) model is formulated to test the influence of various zonal and vehicle characteristics on the prevalence of commercial vehicles in traffic analysis zones (TAZs). When considering a set of alternative TAZs, the MNL model predicts the probability of finding commercial vehicle type t in TAZ i. To our knowledge, no previous study has developed such model. The remainder of this paper is organized as follows. The next section highlights the data used in this analysis. It also discusses the specification of the MNL model. This will be followed by a section to present and discuss the statistical results. Finally, a conclusion to our study will be provided in the last section.


To the Editor:— Two months ago, in the January 20 issue ofThe Journal, you published an article by Drs. Rathmell and Smith to which I must take exception, particularly as it followed so soon after a paper by Dr. H. B. Williams in which also many experts doubt the diagnosis. In this article the child is supposed to have had acute lead poisoning due to only an infinitesimal quantity of lead obtained from orange juice put into an aluminum container. It seems to me unwise to give great publicity to a so-called established case of lead poisoning in a child who is said to have ingested less than 0.02 mg. of lead. Most persons ingest more than that every day in their drinking water, with absolutely no known deleterious effects. An analysis of the dishes was mentioned but no report on this was made, and it is obvious that


Objective To realize internal fixation failure reasons after femoral shaft fractures treatment and to suitable operative treatment.Methods Sixteen patients with internal fixation failures were followed up since 1997, there were two cases with common intramedullary nail bended and one case with plate bended and nine cases with plate fracture and three cases with screw broken or losing. One with plate fracture and screw losing. All patients accepted second surgery with auto-iliac grafting and eleven cases fixed by interlocking nail and three cases by compression plates and tow cases by external fixator.Results All fractures were healed. Knee functions recovered except two cases with the maximum flexion less than 90° . There were complications.Conclusion There were several reasons for internal fixation failures after femoral shaft fractures and surgeons should be very careful for each procedure. Interlocking nail is the first choice for the treatment of the internal fixation failure in femoral shaft fractures.


A disqualification is a message that says something "without really saying it"—one that is evasive, indirect, or effectively ambiguous in some other way. This article describes the rationale for, and development of, an objective method for measuring the degree of disqualification in brief written messages: nonexpert judges independently assess four basic elements of the message (sender, content, receiver, context) for ambiguity, by use of a physical scale of length. The raw scale values are standardized for each judge, and the reliability of these values is quite high. Research uses of the method, as well as its limitations and possible modifications, are discussed.


The morphology evolution of the continuous precipitate Mg_(17)Al_(12) in aging process was studied using KKS phase field model.In the model,the chemical free energy and chemical potential for the precipitate phase and matrix were obtained by using Thermo-Calc software and database.The effects of interfacial energy anisotropy were taken into account by introducing interface anisotropy function, and the effects of micro elastic strain energy were introduced based on the theory of micro elastic strain energy formulated by Khachaturya.It is demonstrated that the precipitate phase has a lath shape when only the interfacial energy anisotropy was considered regardless of the micro elastic strain energy. The precipitate phase grows into a diamond shape when only the micro elastic strain energy was taken into account regardless of the interfacial energy anisotropy.When both the effects of the interfacial energy anisotropy and the micro elastic strain energy were considered in the simulation,the precipitate phase has a lath shape with lozenge ends,which is in agreement with experimental observations.The interfacial energy anisotropy affects the overall morphology of the precipitate,and combining the interfacial energy anisotropy and the micro elastic strain energy results in the lath shape with lozenge ends.


This paper presents an improved adaptive Kalman filter algorithm for wind estimation with unmanned aerial vehicles (UAVs). The wind measurement values with UAVs always include large continuous outlier. At the same time, the noise statistical prior knowledge for wind is insufficient. Firstly, the wind state equation including mean wind and turbulence is established by accurate wind model. Then the three-dimensional measurement equation of wind is established based on the principle of the wind measurement by UAVs. Finally, the wind data measured by the UAVs is processed using improved adaptive Kalman filter. Simulation results demonstrate the feasibility of the approach. And compared with the traditional Kalman filter and the adaptive Kalman filter, the proposed algorithm can reduce the influence of large continuous outliers and ensure the accuracy of wind field estimation.

Seedling growth, described as early vigor, is one essential component of reliable crop establishment and has been reported in many crop species (Lopez-Castaneda et al., 1995 and 1996). Modern wheat varieties exhibit genetic variation in early vigor (Rebetzke and Richards, 1999; Richards and Lukacs, 2002; Maydup et al., 2012). Greater vigor cultivars shade the soil surface faster, thereby reducing evaporative losses from the soil and enhancing the population water-use efficiency (Gregory et al., 2000). It is recognized as a particularly important characteristic for increasing yield potential in dry environments (Siddique et al., 1990; Richards, 2000; Botwright et al., 2002; Richards and Lukacs, 2002). Moreover, rapid early development of leaf area and root system are also associated with increased nitrogen use efficiency (Liao et al., 2004), rates of light interception (Maydup et al., 2012), and weed competitiveness (Coleman et al., 2001; Lemerle et al., 2001). Selection for great early vigor wheat germplasm is favorable to yield improvement under the challenges of agricultural adaptation to global climate change and improving efficiency of inputs. Due to decades of repeated using of founder parents in breeding, the genetic base of modern bread wheat Triticum aestivum L. (2n=6x=42, AABBDD) is rather narrow in recent decades. However, its wild relatives constitute a potential rich source of genetic variation. Bultynck et al. (2004) and ter Steege et al. (2005) found that the common wheat D genome progenitor Aegilops tauschii Coss (2n=2x=14, DD). showed a very rapid leaf expansion rate at the seedling stage. With the help of molecular markers and marker-based genetic maps, genetic dissection for early vigor related traits has been reported in several germplasm under different growing conditions, and QTLs for early vigor related traits were distributed through almost whole genome of wheat (ter Steege et al., 2005; An et al., 2006; Sanguineti et al., 2007; Landjeva et al., 2008 and 2010; Ibrahim et al., 2010 and 2012; Guo et al., 2012; Ren et al., 2012a, b). 'Chuanmai 42' derived from synthetic hexaploid wheat (SHW, 2n=6x=42, AABBDD) carried elite genes from tetraploid wheat Triticum turgidum L. (2n=4x=28, AABB) Pak. J. Agri. Sci., Vol. 55(1), 33-45; 2017 ISSN (Print) 0552-9034, ISSN (Online) 2076-0906 DOI: 10.21162/PAKJAS/18.4488 http://www.pakjas.com.pk


Diffusion ability is an important indicator of shale gas reservoir quality. In this paper, the diffusion coefficient of the Longmaxi Formation is measured via the free hydrocarbon concentration method, and the diffusion ability, influencing factors, and seepage flow are discussed. Results show that the diffusion coefficient of the Longmaxi Formation is between 1.23 × 10−5 and 2.98 × 10−5 cm2 s−1 with an average value of 2.19 × 10−5 cm2 s−1 (confining pressure 3.0 MPa). The diffusion coefficient is calculated for various pressures using an empirical formula (D = 0.339K0.67/M0.5) and experimentally measured data. The estimated, temperature-corrected diffusion coefficient of the Longmaxi Formation is 3.94 × 10−6–7.24 × 10−6 cm2 s−1 with an average value of 5.28 × 10−6 cm2 s−1 for depths from 1000 to 3000 m (confining pressure 16.7–39.7 MPa). The diffusion coefficient increases with increasing depth of the reservoir due to the changes in pressure and temperature. Fitting parameters show that the porosity of the reservoir and clay minerals is positively correlated with the diffusion coefficient, and the diffusion coefficient is also related to factors such as total organic carbon and the maximum reflectance of vitrinite (Ro). The diffusion flow rate is 0.177–0.204 m3 d−1 with an average of 0.182 m3 d−1. Linear seepage flow is 4.95 × 10−4–14.29 × 10−4 m3 d−1 with an average of 8.87 × 10−4 m3 d−1, calculated from the diffusion coefficient and permeability per unit flow. These results indicate that the migration of shale gas in the deep region of the reservoir is mainly by diffusion. Therefore, diffusion is an important shale gas flow mechanism.

Nonexacting purineless mutants were isolated from an inosine-forming adenine auxotroph of Bacillus pumilus. Some of them accumulated Bratton-Marshall reaction-positive material in their culture fluid. The product was isolated in crystalline form and identified with 5(4)-amino-4(5)-imidazolecarboxamide riboside (AICA-Riboside).AICA-Riboside accumulated by the nonexacting purineless mutants was less than inosine accumulated by their parent adenine auxotroph.A number of mutants that require adenine specifically were isolated from AICA-Riboside-forming purineless mutants. More than half of them accumulated a large amount of AICA-Riboside as compared with their parents, nonexacting purine auxotrophs. The rest of adenine-requiring mutants from purineless mutants lost the ability to accumulate AICA-Riboside.The effect of hypoxanthine on the accumulation of ACIA-Riboside by these auxotrophs was also examined.

In this article, the two complex phenomena of poverty and conflict are problematised and linked to each other with the purpose of exploring possible causal relationships, which may have policy relevance for conflict resolution as well as for international development assistance. The complexity of the poverty-conflict relationship is multiplied by the inherent diffuseness of the two phenomena in question. The fact that a generalised connection between reducing poverty and enhancing security can be taken for granted - simply because of common sense reasons - does not tell us very much about what particular patterns of poverty would lead to particular varieties of social violence, and what specific development activities would have a positive role to play in conflict reduction. There is thus no alternative but to go further into the various meanings of the two concepts.


Edible electronic devices are orally deployable electrified medical devices that have great potential to diagnose and treat many types of diseases. Interest in edible electronic devices has accelerated in recent years for several reasons. First, the role of gut health on overall health is becoming apparent.


− The growth in demand for security in services accessible via portable devices, like Personal Digital Assistants and Cell-phones, that require wireless networks to connect to distributed servers, has prompted active research. Biometric verification methods such as voice recognition (VR) may prove very effective for these. The major hindrance for the popularity in implementation of VR in such systems has been achieving efficiency and coping with the requirements of very large databases and high processing power. For real time VR as required by these applications, the design architecture may require acceleration in processing power for any embedded electronic system. Thus, software algorithms must be implemented in embedded processors or FPGAs, to achieve high recognition rate. In this paper, novel idea for a simplified macro level model of hardware prototyping of VR to be used as a biometric security measure is presented. The heart of the engine proposed is a voice recognizer capable of distinguishing between speakers using text-dependent algorithms by extracting time-domain descriptors of the spoken word. As a case study, we also propose a possible secure mechanism using VR biometric as embedded hardware, which may help improve equipment and network security in 2G/3G wireless systems and similar applications.


The Taylor operational matrix of integration and the Taylor product operational matrix are introduced. These two operational matrices are applied to approximation of solutions of Fredholm and Volterra integral equations. The proposed method reduces solution of integral equations to the successive solution of a set of linear algebraic equations in matrix form. Owing to the simplicity of the operational matrix of integration, and the product operational matrix of the Taylor series, the algorithms derived possess considerable computational advantages over the orthogonal-polynomial approximation, provided that both input and output are analytic functions of t.


This paper presents a novel absorbing boundary condition (ABC) that can accurately simulate elastic wave absorption into unbounded exteriors that are often encountered in problems related to seismology and soil-structure interaction. By linking the material-damping ABCs (the perfectly matched layers) with differential-equation-based ABCs, the paper draws on their respective advantages and presents an ABC named the continued fraction ABC (CFABC). The CFABC is highly efficient and appears to be the first ABC applicable for polygonal computational domains. Representative numerical examples are presented to illustrate the effectiveness of the proposed ABCs.


This is a sweeping study of world cinema, illustrating how its creative peaks stem from the urge to reveal otherwise hidden political and social dimensions of reality. "World Cinema and the Ethics of Realism" is a highly original study. It breaks away from the binary divisions which underpin most of film theory, and challenges traditional views of cinematic realism, drawing instead on the filmmaker's commitment to truth and to film's material bond with the real. Nagib conducts comparative case studies drawn from a wide range of realist trends, including the Japanese New Wave, the nouvelle vague, the Cinema Novo, the New German Cinema, the Inuit Indigenous Cinema, the Taiwan New Cinema and the New Brazilian Cinema. She reveals that these creative peaks are animated by the desire to reveal concealed or unknown political, social, psychological or mystical dimensions of reality - as observed in the various cycles of new waves and new cinemas across film history and geography. "World Cinema and the Ethics of Realism" is groundbreaking scholarship that surveys and defines World Cinema not as the opposite of Hollywood, but in positive terms; and draws upon the work of Badiou and Ranciere to take film theory in a bold new direction.


Using microsimulation techniques to estimate the impact of welfare reform in New York, we find that 5 years after federal and state reforms child-care use and costs will rise substantially and families will bear most of these costs. When family incomes are adjusted for child-care costs, most single-mother families will continue to be poor even with greater earnings, the Earned Income Tax Credit, and food stamps. The distribution of child-care costs between government and families, and the implications for poverty, will depend on the extent to which government subsidizes the child-care costs of single mothers.

As developmental science continues to grow in scope as a field, new and innovative areas of scholarship continue to emerge. To highlight the nature, importance, and potential for theory-predicated and methodologically rigorous applications of developmental science for these new areas of developmental scholarship, Applied Developmental Science will publish an occasional series of "spotlight" articles focused on these emerging areas of work. These spotlight series will involve publishing one or two articles on the topic per issue across several issues. The hope for the spotlight series is that it will both synthesize existing work and provide a useful pathway for future research. The first set of spotlight articles will focus on cuttingedge research in human-animal interaction (HAI), specifically within the area of animal-assisted interventions (AAI) aimed at promoting health and well-being. HAI and AAI research has expanded significantly within the last decade, and a critical "tipping point" is being approached. There is intellectual momentum, funding, and research infrastructure that are coalescing to bring the field to a new level of scholarship, one extending beyond anecdotal evidence and pilot studies. We believe, therefore, that it is propitious to now assess the state of the field of animal-assisted intervention research, and to articulate an agenda for future work. Given the ubiquitous and diverse nature of humananimal relationships across the life span, and the myriad ways in which interaction with animals can be a part of the dynamic developmental process, this topic is of particular importance for developmental scientists. We look forward to sharing a series of five articles over the next two issues of Applied Developmental Science, all focused on various research and practice issues related to the implementation and study of animalassisted programs.


The singlet potential energy surface of Si 2 H 2 has been explored by using ab initio theoretical methods. Complete geometry optimizations and vibrational frequency analyses were performed for 11 different structural isomers at the self-consistent field (SCF) and single and double excitation configuration interaction (CISD) levels of theory using double-ζ plus polarization (DZP) and triple-ζ plus double polarization (TZ2P) basis sets. Several extended basis sets including diffuse and higher angular momentum functions were employed in determining the final energetics of this system. Our analysis of the potential energy surface confirms that the global minimum is a C 2υ dibridged structure and reveals two minima and three transition states in the range 10-15 kcal/mol above the dibridged


Bohai SZ36-1 Oilfield is currently the only one that has industrial application of association polymer flooding.There are complex conditions existing there such as limited space of offshore platform,sand control completion with wire wrapped screen and gravel pack,and high volume production in single layer.Viscosity loss in the injection allocation process was studied by laboratory and field tests.Results showed that mechanical shearing of operating system and solution water quality were important factors influencing viscosity loss.Polymer injection sections like injection pump and perforation hole can affect viscosity loss more than 60%.Also,it was found that with bivalent cation content increasing in solution water,the viscosity loss rate of association polymer stepped up.Additionally,fast dissolution way by micelle grinding can result in slight viscosity loss of associated polymer solution.The study provides a reference to improving the effective polymer viscosity and guaranteeing quality of polymer flooding.

Networks of the Theban Desert: social, economic, and religious interactions in Late Byzantine and Early Islamic Thebes This thesis examines the range of interactions which bound the Egyptian town of Jeme (Medinet Habu), and the nearby monasteries of the Theban necropolis, to each other and to other, more distant communities in the seventh and eighth centuries CE. In doing so, it also seeks to assess the importance of this west Theban community in the exchange networks that covered Egypt as a whole, and the Hermonthite and Koptite nomes in particular. The communities of western Thebes, and especially the town of Jeme, are ideal for this study since large amounts of documentary evidence in Coptic survive from multiple sites within well-defined chronological limits. While Jeme is the main focus, this thesis also concentrates on three of the many contemporary monastic communities in the area: the monastery of Apa Phoibammon, the monastery of Epiphanius, and the solitary monk Frange. These three communities are ideal since they have the largest bodies of documentary evidence attesting them, which makes network studies more viable, and since they are of different sizes and natures (monastery, laura, hermitage), making them a representative sample of the range of communities present on the Theban mountain. Where relevant, material from other sites, in particular the monastery of Apa Paul, is also taken into consideration. The relationship between Jeme and the larger monastic communities of western Thebes was close and interdependent, and it is argued that the presence of Jeme allowed the monasteries to flourish, and that their success in turn increased Jeme's own status. These close knit communities then formed a regional hub which, while not a site of the same importance as the nome capitals, was still of significant economic and religious importance to the communities of the Hermonthite and Koptite nomes. An understanding of the nature of the west Theban communities and how they fitted in to broader exchange networks not only demonstrates the symbiotic relationship between monastic and secular communities, but provides the groundwork for future sociological studies of the region, whose discussions can now be framed in the light of the regional importance of western Thebes.

New azomethine metal complexes were synthesized systematically and characterized. Beryllium, magnesium, or zinc ions were used as a central metal cation and aromatic azomethines ( L1-L4) were employed as a chelating anionic ligand. Emission peaks of the complexes in both solution and solid states were observed mostly at the region of 400-500 nm in the luminescence spectra, where blue light was emitted. Three of them (BeL1 (I ), ZnL2 (II ), and ZnL3 ( III )) were sublimable and thus were applied to the organic light-emitting devices (OLED) as an emitting layer, respectively. The device including the emitting layer of I exhibited white emission with the broad luminescence spectral range. The device with the emitting layer of II showed blue luminescence with the maximum emission peak at 460 nm. Their ionization potentials, electron affinities, and electrochemical band gaps were investigated with cyclic voltammetry. The electrochemical gaps of 2.98 for I , 2.70 for II , and 2.63 eV for III were found to be consistent with their respective optical band gaps of 3.01, 2.95 and 2.61 eV within an experimental error. The structure of OLED manufactured in this study reveals that these complexes can work as electron transporting materials as well.

This paper describes the design of a PLL-based and integer-N quotient frequency synthesizer (QFS) suitable for V, E and W multiband mm-wave applications. The complementary NMOS and PMOS dual-injection structure with independent gate bias and co-tuning technology are adopted to improve injection efficiency and extend frequency locking range of ILFD. The ameliorated pseudo-differential cascode structure is applied in buffer stages to enhance gain and stability performance. The frequency synthesizer, fabricated in low cost 0.13μm CMOS process, can provide over +1.5dBm output power at 50ohm load within a wide frequency range from 27.38 to 33.5GHz and the closed-loop phase noise of -111.25 to -110.2dBc/Hz at 10MHz offset from carrier frequency and -125dBc/Hz at 100MHz offset while drawing 70mA current (not including testing buffers) from 2.5V power supply.


Background: Ovarian tumors are a heterogeneous group of neoplasm that have become increasingly important now-a-days because of their large variety of neoplastic entities and gradually increased rate of mortality due to female genital cancers. Objectives: The aim of this study was to analyze the histopathological pattern and clinical presentation of malignant ovarian tumors according to the WHO classification of ovarian tumors [2003] in a tertiary care center of Dhaka, Bangladesh. Materials and Methods: This retrospective study included and studied a total of 54 cases of malignant ovarian tumors at the Department of Obstetrics and Gynecology, Popular Medical College Hospital, Dhaka, Bangladesh over a period of 3 years from Jan 2015 to Dec 2017. Results: The mean age was 47.44±14.24 years old (age ranged from 20-70 years). Of the 54 malignant ovarian tumors studied, the commonest histological pattern observed in the study was serous cyst adenocarcinoma constituting 26 cases (48.15%) followed by adenocarcinoma of ovary (25.9%), mucinous cyst adenocarcinoma (14.8%), endometriod adenocarcinoma (3.7%), dysgerminoma (3.7%) and ovarian choriocarcinoma (3.7%). High level of serum CA125 was found in most of the cases (n=48; 88.89%). The chief complaints were abdominal pain (n=38; 70.37%) and abdominal distension (n=29; 53.70%). Majority were admitted with less than one month duration of symptoms. The size of the tumor varied from 2.2 to 20 cm. All the patients were admitted in III and IV stage. Conclusions: Serous cyst adenocarcinoma was the common finding of this study. The prognosis and varying therapeutic strategies of malignant ovarian tumors necessitate an accurate histopathological evaluation.


The deficit of working memory is considered to be a central deficit in ADHD that is responsible for cognitive and behavioral problems. It is related to the defective function of the frontal cortex. The concurrent effect of working memory training is the impulsivity decrease in individuals suffering from ADHD. Patients with a diagnosed hyperkinetic disorder were first examined using IVA + Plus and Conners' Continuous Performance Test II. Then they underwent working memory training using COGMED program. Subsequently, IVA + Plus and Conners' Continuous Performance Test II were performed again. We managed to prove a statistically significant improvement especially in the visual part of the working memory.


In order to solve the problem that the ORB-SLAM2 algorithm will cause positioning failure in a scene with a relatively single texture, the line features in the environment are extracted and matched. The point and line feature constraints are used to ensure the positioning accuracy. Firstly, the acquired image was processed by gradient density filtering. Then the feature points in the image were extracted by the ORB algorithm, the linear features in the image were extracted by the LSD algorithm and the linear features in the image were described by the LBD algorithm. In the above process, a certain strategy was used to select the keyframes. Next the point and line reprojection error term was constructed and the weighting strategy was used to weight the reprojection error. Finally, the nonlinear optimization method was used to obtain accurate pose information. The experimental results on the EuRoC dataset prove that the accuracy of the positioning algorithm fusing point and line features is higher than that of the positioning algorithm using only point features.


PT PLN (Persero) is a state-owned electricity company of the Republic of Indonesia that has a long-term power plant project planning. In the electricity supply business plan 2018-2027 it is stated that in 2027 the number of PLN customers is estimated to reach 82.11 million in the household sector and 7 million in the business sector. With the increasing number of their customers, PLN is required to know about the amount of electricity that must be distributed. This study uses linear and quadratic regression models to predict the amount of electricity distributed by PLN in 2027, especially for the household and business sectors using available historical data. The data contains the number of PLN customers and the amount of electricity distributed from 1995 to 2015. This study shows that the linear and quadratic regression models have competitive results based on the coefficient of determination. Since the quadratic regression method has a higher R2 value, then this model can be used to predict electricity distributed in 2027. Using the quadratic model, the amount of electricity distributed in 2027 is estimated at 157,000.1 GWh in the household sector and 109,175.0 GWh in the business sector.


A monitoring study was carried out in 1998-1999 on a medium-sized (c. 4580 km2) watershed of the Dyle (or Dijle) river in central Belgium, composed of both rural and urbanized areas. This watershed may be considered as representative of a large part of the country. Samples were taken each month from seven sites along the course of the river, plus one from its major affluent the Demer. The eight molecules monitored were the main herbicides used on the major crops in the area, plus some used in nonagricultural sectors. The concentrations found were mostly in the 0-3 μg/L range, with some peaks between 3 and 14 μg/L. The averages over all spring and summer samples analyzed ranged from 0.14 (bentazone) to 1.54 μg/L (diuron). Time and space specific patterns could be observed.

Screw piles are considered as one of the solutions in different complications projects. Performance of circular screw piles group subjected to compressive load and embedded in two layers; soft clay and compacted sandy soils is investigated in this study. The thickness of two layers soft clay and sand soil is 250 mm and 350 mm respectively which are prepared after compacted to sub layers in the container. By choosing different slenderness ratios of L/ D 25, 32 and 39, many model tests were achieved on screw piles group. Single and double helix plates were used in screw piles with constant of helix spacing 60mm. A square pattern of screw piles group with different spacing between piles (1.5Dh, 3Dh, 4.5Dh), where Dh is diameter of helix is adopted in this study. The results of this study showed that the ultimate capacity of piles group was increased by increasing the spacing between the piles until reached spacing 3Dh then begin to decrease when piles extended in sandy soil, while in soft clay the ultimate capacity increase with decrease piles spacing in two cases single and double helix. The increasing percentages for pile spacing 3Dh and 4.5Dh are (55.3% and 39.4%) respectively for L/D ratio 32 and (27.2% and 23.8%) respectively for L/D ratio 39. Also, it is recommended to use screw piles group in case of deep layer of soft clay laying on sandy layer due to high increase in compressive resistance capacity of group when extended in sandy layer.


The main objective of this study is to estimate the economic value of Sheka forest, one of the natural forests located in Southern Nations, Nationalities, and Peoples (SNNP) Regional State of Ethiopia. It has a potential to contribute towards the economic development of the region. To estimate conservation value of Sheka forest, contingent valuation method (CVM) were employed by using double-bounded dichotomous choice format. To estimate mean willingness to pay and to identify determinants of household's willingness to pay probit model and seemingly unrelated bivariate probit model were employed. To measure household's maximum willingness to pay for forest conservation Tobit model were used. The result showed that 94.91% of households were willing to pay for the conservation of Sheka forest. As a result, the mean maximum willingness to pay was 47.97 ETB. The households mean willingness to pay for Sheka forest was found to be 39.07ETB from probit model, 39.65 and 58.51ETB from bivariate probit first and second equation respectively.

Let $\mathfrak{P}$ be the class of all finite posets. For $P, Q \in \mathfrak{P}$, let ${\cal H}(P,Q)$ and ${\cal S}(P,Q)$ be the sets of order homomorphisms and of strict order homomorphisms from $P$ to $Q$, respectively. From an earlier investigation we know, that for $R, S \in \mathfrak{P}$, the relation "$\# {\cal S}(P,R) \leq \# {\cal S}(P,S)$ for all $P \in \mathfrak{P}$" implies "$\# {\cal H}(P,R) \leq \# {\cal H}(P,S)$ for all $P \in \mathfrak{P}$". Now we ask for the inverse: For which posets $R, S \in \mathfrak{P}$ does the existence of a poset $P \in \mathfrak{P}$ with $\# {\cal S}(P,R) > \# {\cal S}(P,S)$ imply the existence of a poset $Q \in \mathfrak{P}$ with $\# {\cal H}(Q,R) > \# {\cal H}(Q,S)$? We prove that this is true for posets $P, R$, and $S$ belonging to certain classes. In particular, the implication holds for all flat posets $R$ and $S$.


electroniccounter measure the intervals. In addi tion,the accuracyofthe timingmarksonthe ECG recordingstrips was determined by comparison with the electronic counter's re suIts. Thirty-six studies were selected from 29 patients who had un dergone restingejection-fractionmeasurementsbetweenJanuary and October, 1978.Selectionwasbasedonthepresenceofa clearly legibleECG recordingshowingthe end-diastolicand end-systolic windows,presenceof normalsinusrhythm with lessthan 5%pre mature beats, and a high-quality, computer-generated, left-yen tricular time-activitycurve.All patients had a QRS duration less than 0.08 sec, except for one patient with right bundle-branch block and left anterior hemiblock. Many ofthc patients were taking propranolol. Twenty-three additional studies were selected from eight of the above patients, covering each stage of graded supine exercise to a symptom-limited maximum. Overall, there were 59 studies in whichthe timingofend-systole,as definedbythe ECGgate,could be compared withend-systoledefinedby the time-activitycurves. The ECG-gate time of end-systole,defined as the time from R wave to the mid-point of a 40-msec systolic window, was measured from the ECG tracing providedby the ECG gate. For both heart rate and time to end-systole,six to ten consecutivecycles were averaged. Left-ventriculartime-activitycurvesweregenerated usingthis laboratory's ECG-synchronized blood-poolimaging techniques as previouslydescribed (2). The framing rate used was 25/sec, resulting in 40-msec frames. To optimize the determination of the timing of end-systole, the six or seven minimum points of the time-activitycurvewerefittedwitha parabolausingtheleast mean-squares technique. The minimum point was then taken as thetimeof end-systole. A commercialECGgate testedto evaluateUsabilityto predictaccurately the time of end-systole.The predictedtimes followedthe manufacturer'sspecifI-cationsquitewell. Thesetimeswerecomparedwfththe actualtimesof end-aye tole as determinedby computer-derivedleft-ventriculartime-activitycurvesusing Tc49m-labeled red blood cells. Afthoughthere was moderate scafter, the predict ed times of end-systole correlated well wfth the actual times (n 59, r 0.829). If the left-ventricular ejection fraction was calculated using the predicted time of end-systole, the error would be 0.03, or less, for 95% of the subjects.


There are many reasons for which proficiency in foreign languages has become indispensible in today's world. Language schools and classes are enjoying ever growing popularity. The rich offer of language schools in Lublin advertises a wide spectrum of teaching methods with the aim of attracting new clients and enticing potential students. This abundance begs the question of how effective the methods employed by those schools really are in the process of foreign language teaching.


The EU expansion in 2004 will completely change the face of the European community of states. The structure of the power supply system, too, will undergo major changes. Both the expansion of the EU and the reliability of electricity supply are topical problems in need of perspectives of solutions. Nuclear power can and will contribute to these solutions. For Germany, it is imperative that an energy consensus be worked out and put into effect across all party lines in an effort to create reliable framework conditions for the next 20 or 30 years. The goal must be a balanced energy mix also ensuring the competitiveness of Germany as an industrialized country. The individual strengths of each of the energy sources must be pooled so as to result in an optimum. Foregoing the use of nuclear power in the future is wrong in respect of the national economy, power economy, and climate policy. Developments in the neighboring countries in Europe and worldwide document that the opting-out policy of the German federal government is an approach peculiar to Germany. The final storage of radioactive waste in Germany is a topic to be finalized speedily. The Konrad and Gorleben mines constitute a promising concept of final storage of all types of radioactive waste in Germany. This goal must be pursued further in a firm policy and must not be delayed by new site selection procedures. In the field of nuclear research, Germany must not be separated from international developments. Nuclear competence must be preserved and promoted. The future power supply situation in Europe is characterized by the need for a considerable addition of generating capacity. As is demonstrated by the project of the new nuclearpower plant to be built in Finland, nuclear power is going to play an important role in meeting this need.

The picture that most of us carry in our minds of how drugs block ion channels is taken from the classic studies of Hille1 involving local anesthetics and Armstrong2 involving tetraethylammonium (TEA) derivatives. This picture is elegant in its simplicity yet robust enough to have provided a conceptual framework for explaining a variety of experimental results and for developing a rigorous model of the drug-channel interaction.3 4 We see cationic drugs entering the channel from the cytoplasmic side, only after the channel has opened, and binding to a site 20% to 50% of the way into the membrane field. Neutral drugs are not restricted to the open pore but can also access and leave the blocking site via a separate hydrophobic pathway. The movement of drugs into and out of the channel is ultimately governed by membrane potential and channel gating, producing use-dependent changes in membrane current and electrophysiological activity. Larger and more hydrophilic drugs move slowly and have slower use-dependent kinetics. Smaller and more hydrophobic drugs show rapid use dependence.

Molecular biology techniques have greatly refined this picture over the past several years by providing new and important structural detail. For K+ channels, TEA binding has been localized to a critical threonine residue in the P region of the channel that is highly conserved among different K+ channel subtypes.5 Specific amino acid residues in the predicted transmembrane S6 segment of domain IV (IVS6) were found to be critical determinants of local anesthetic action in Na+ channels6 7 and to govern the block of Ca2+ channels …

Dust-ion-acoustic solitary waves in a multi-component unmagnetized dusty plasma containing negatively charged dust particles, nonisothermal electrons and nonthermal ions, have been investigated. The Sagdeev potential approach is applied to study the large amplitude solitary waves. The intermediate integral forms of Korteweg-de Vries (KdV) and modified Korteweg-de Vries (mKdV) equations are derived under different approximations to obtain the solutions of small amplitude solitary waves of different forms. Spiky and Explosive solitary waves as well as double layers are found to exist. The parameters , , , , an d M     , representing the population of nonthermal ions, ratio of free and trapped electron's temperatures, Mach number, temperature ratio of ion and free electrons, and the density ratio respectively, are found to play a very important role in the formation of solitary waves.


The popularity of community based Question Answering (cQA) portals gives rise to the fact that the quality of answer content usually range from very high to very low. In this paper, we exploit social features and topic based features to address a key issue in Chinese cQA portals: predicting the answer quality. Different from previous work, we first investigate and analyze the answers of Haidu Zhidao based on the social features extracted from different aspects. Thereafter, we build a predictive model through machine learning based on the proposed features to make prediction. Extensive experimental results demonstrate the distinguishing ability of social features to predict answer quality. Moreover, we make systematic comparison on different groups of features and find that answer statistic features play a key role in improving the overall performance. In addition, we also find that topic based features outperform word based features a lot.


Static, axisymmetric solutions form a large class of important black holes in classical GR. In four dimensions, the existence of their most general metric ansatz relies on the fact that two-dimensional subspaces of the tangent space at each point spanned by vectors orthogonal to the time-translation and rotation Killing fields are integrable. This was first proved by Wald via an application of Frobenius theorem. In this note, we furnish an elementary proof for this theorem by Wald in arbitrary dimensions which yields the metric ansatz for the most general solution of the D-dimensional vacuum Einstein equations that admits D-2 orthogonal and commuting Killing vector fields.


The POE/PP thermoplastic vulcanizate(TPV) was prepared by using twin-screw extruder,and the effects of screw rotation speed and curing temperature on the microstructure and properties of POE/PP TPV were investigated.The results showed that,the POE was the dispersed phase and the PP was the continuous phase in the POE/PP TPV;as the screw rotation speed was 400 r·min-1 and the curing temperature was 190~200 ℃,the better comprehensive physical properties of TPV were obtained.


Rock fracturing technique through fluid injection into the wellbore has been widely used to extract geothermal heat and to enhance oil and gas production. Single fracture formation is ideal for the production. However, it is very difficult to form single fracture formation. Instead, the formation of segmented fracture is a common phenomenon. Therefore, design parameters are expected to be different from those of single fracture because of mechanical interaction between segmented fractures. In this paper, design parameters such as length, aperture, and net pressure are evaluated by using model of segmented fracture in which numerical technique is incorporated to consider mechanical interaction between segments. Results show that the existence of fracture segmentation affects design parameters in fracturing treatment in rock by fluid injection.

At the end of each exposure the coupons were examined visually for rusting or no rusting. The outputs of ACM sensor and RH (relative humidity) sensor were measured by a data logger


We introduce a sketch-based 3D modeling system using Virtual Reality (VR) with a Head Mounted Display (HMD). The system enables users to sketch freely 3D objects in various colors, arrange and situate the objects in the environment and finally export the virtual objects into a 3D file for fabrication. We evaluated the system in a small workshop with users, and the system was found to have a possibility for rapid ideation and for spatially conceptualizing ideas.


The utility model discloses a device for drainage and seepage at the bottom of a filmed seepage-proofing phosphogypsum yard, comprising a phosphogypsum yard starter dam with an HDPE (High-Density Poly Ethylene) film paved on an upstream slope surface, wherein a reinforced concrete box culvert is arranged on the dame of the upstream face of the starter dam; a plastic blind drain is filled in the reinforced concrete box culvert; a stainless steel pipe capable of leading out seeping water to the outside of the reinforced concrete box culvert is arranged at the tail part of the reinforced concrete box culvert; and the stainless steel pipe is connected to an HDPE pipe embedded in the bottom of the starter dam. The drainage-seepage system of the device provided by the utility model leads out water contained in phosphogypsum stored in the storage basin under the elevation of the starter dame and water accumulated from rainfall and leads the water downstream from the bottom of the dam to a regulating water pool outside the yard; therefore, water in phosphogypsum can be drained as quickly as possible, drainage and solidification of phosphogypsum are sped up and the stability of the phosphogypsum yard is guaranteed.


n -Al 2 O 3 and f -Al 2 O 3 were used to remove selenite (SeO<$>_3^{2-}<$>) from aqueous solution. Various adsorption parameters studied are time, temperature, pH, concentration of adsorbent and adsorbate and in saline(0.1 v M KCl)/nonsaline medium. At pH h 8.1, adsorption is higher and thereafter it decreases and the percentage of adsorption decreases with the rise in temperature. Adsorption capacities ( X m ) of the samples calculated from the Langmuir equation was found to be 1.9 v mmol v Se v g m 1 in nonsaline medium, while it is 2.6 v mmol v Se v g m 1 in saline medium for n -Al 2 O 3 . Adsorption capacity of n -Al 2 O 3 is higher than f -Al 2 O 3 .


Applying the parabolic approximation to the wave equation results in a far simpler and more tractable model for ultrasound propagation. The approximate (Kuznetsov)model assumes that sound propagates predominantly in the axial direction and that the pressure amplitude is a slowly varying function of the axial coordinate. Since the terms "predominantly" and "slowly" ar far from quantitative descriptors, and since recent work shows excellent agreement between simulation and experiment at surprisingly low F-numbers, the presentwork seeks tomore firmly establish the region of validity of this approximation for focused ultrasound sources. To this end, the focused beam of a flat panel transducer is modeled using both the full wave equation and its parabolic approximation. The simulation results are compared as a function of focusing depth and beam steering angle.


Objectives:  Overexpression of FK506 binding protein 51 (FKBP51) in megakaryocytic progenitor cells generated from purified CD34+ cells in patients with idiopathic myelofibrosis (IMF) has been demonstrated. It has been suggested that FKBP51 is involved in the dysregulation of the apoptotic programme with consecutive prolongation of cell survival. The knowledge of FKBP51 and its expression in bone marrow cells and mature megakaryocytes in non‐neoplastic haematopoiesis and IMF is sparse.

International police development (IPD) has a poor record of success, due in large part to failures in assessing needs and planning interventions. Too often the more profound, yet complex, challenges of institutional and constitutional reform give way to the obvious and comparatively easy delivery of training and equipment. Police accountability, arguably the most important component of democratic policing, needs to be assessed in a consistent and rational manner if deployment of resources and effort on the part of donors are to result in more convincing outcomes. It is argued here that the provisions by which effective police accountability is brought about should be the first priority of IPD missions. Drawing on the academic and policy literature, this article presents a model of police accountability which can form the basis for needs assessment as an aid to IPD planning.


Two isoforms of ACC oxidase (ACO) (EC 1.4.3), expressed differentially during leaf ontogeny in white clover (Trifolium repens L.), have been identified and purified to homogeneity. One isoform, designated MGI, was purified from mature green leaf tissue while the second isoform, designated SEII, was purified from senescent leaf tissue. The isolation and purification of these isoforms were achieved using a combination of hydrophobic interaction chromatography, anion exchange chromatography, chromatofocusing and gel filtration column chromatography. The M r of both MGI and SEII was determined to be 37.5 kDa by gel filtration, and 37 kDa (MGI), 35 kDa (SEII) by SDS-PAGE, indicating that both isoforms are active as monomers. During purification, both isoforms were recognised by a polyclonal antibody directed against a recombinant polypeptide derived from a white clover ACO gene expressed in mature green leaf tissue, TR-AC02. In addition to molecular mass, differences between the two isoforms were observed in terms of pH optima, isoelectric point (pI), K m for ACC, optimal requirements for the co-substrate ascorbate, and NaHCO 3 and Fe 2+ as co-factors. The identification of distinct ACC oxidases from the same tissue at different developmental stages shows that the now widely observed transcriptional regulation of the ACO gene family in higher plants is also expressed in terms of differential regulation of enzyme isoforms.

SUMMARY

The growth of wheat seedlings which were already mycorrhizal when transplanted to a field deficient in phosphorus was improved compared with non-mycorrhizal controls, and grain yield was increased three-fold by the fungus, indicating that Endogone stimulated growth and increased yield. Differences between mycorrhizal and non-mycorrhizal wheat were eliminated by the application of phosphate fertilizer, indicating that the fungus does not enhance wheat growth in soils containing enough available phosphate. It is probable that the mycorrhizal effect is primarily to improve the supply of phosphate. There were clear relationships between spore number in the soil and mycorrhizal development and between the extent of root infection and increased growth. The extent of root infection was greatest in mycorrhizal plants in soil not supplemented with phosphate and it decreased in inoculated plants in the plot supplemented with superphosphate.

The non-centrospermous and non-zygophyllaceous weeds growing on the experimental field had typical vesicular arbuscular infection and indigenous Endogone spores in their rhizospheres. The centrospermous plants were non-mycorrhizal and had no Endogone spores in their rhizospheres.


A radar operator may encounter a situation in which a storm with a relatively weak radar appearance produces a significant amount of wind damage. One such case occurred during the early evening on 6 September 1999 when a broken line of strong to severe thunderstorms developed in the wake of Hurricane Dennis across western portions of the Warning Forecast Office (WFO) Wilmington North Carolina (ILM) County Warning Area (CWA). The convection began along a sub-synoptic trough during the afternoon, and interacted with outflow boundaries and a sea breeze front. Several warnings were issued during the event, particularly for the thunderstorms that depicted very high vertical integrated liquids (VIL), exhibited atypical storm motion, or attained an organized structure per base reflectivity displays.
