An NE213 liquid scintillator operating as a proton recoil spectrometer was utilised to determine the absolute fluence of monoenergetic neutrons in three quasi-monoenergetic fields. Events due to the neutrons of interest were selected by time-of-flight and a portion of the measured response function associated with protons, identified using pulse shape discrimination. Neutron fluence was evaluated by matching a theoretical detector response to the measured data in a region where only events from elastic scattering off hydrogen nuclei contribute to the pulse-height spectrum. The absolute fluence, normalised to unit beam charge, determined for neutrons of energies 25.5, 42.0 and 62.6 MeV was respectively 5.3 (±0.4), 5.4 (±0.4) and 5.9 (±0.5) cm -2 ,nC -1 . The results were corroborated by estimates obtained from measurements of induced activity produced via the 12 C(n,2n) 11 C reaction in the organic compound xylene.


Background:  Since the start of Long Term Nursing Insurance in Japan in April 2000, there has been much discussion about and emphasis on leading healthy and active twilight years, without ever being bedridden if possible. In an attempt to address some of these concerns, this comparative study examines the factors associated with dependence in the activities of daily living (ADL) in two samples of elderly people living in two different environments.


Many studies have been conducted around the problem of allusion in the world and have not yet ceased to be relevant. The allusion is very complex, diverse, and the ways of transmission in the artistic text are different. Closely related to history. That is, it is reflected in the artistic text by indirect references to historical data. This article discusses the category of historical discourse and features of allusion and interpretation of historical facts in an artistic text. By studying the allusion, researchers pay attention to its functions, typologies and types, and specific characteristics. If we consider history and allusion in a very close relationship, it is obvious that allusion has its own place in the transmission of historical discourse in the artistic text in a work of art. In this article, the historical inscriptions in the text of M.Magauin's work «Kyрshak beauty» is relatively analyzed within the framework of scientific-historical, socio-political, artistic-historical, and cultural discourses. The influence of a historical and artistic text on historical consciousness is studied. The article is guided by the works of such scientists as N.Fateeva, A.N. Pasco, J.Weixlmann, A. G. Mamaeva, A. A. Pelttari, A. S. Adilova on the topic of discourse. Attempts are made to identify the features of the relationship between allusion and historical discourse. In the course of the study, methods of comparison, comparison-analysis, interpretation, semantic, were used.

Denmark; Dunedin, New Zealand; Freiburg, Germany; Mexico City, Mexico; and Portland, Oregon. Wrapping up, it is a sad reflection of the state of the UK's governance, not to mention other nation states, that so much time has to be devoted to national and international politics rather than cities and communities. Not all readers will agree with Hambleton's detailed critique. However, if they are concerned about people and the planet, they are likely to agree with the book's trajectory. Significantly, the book contains a not-so-subliminal message, i.e., that after World War II, the UK rose to the challenge of the postwar recovery. It created the welfare state despite the prevailing austerity. The pandemic shock offers the opportunity for governments to do something similar once again, this time, he hopes, saving the planet as well as the people. Hambleton makes clear that there is no shortage of ideas. There are many models for governments and cities to draw on. Finally, I'm guilty of failing to highlight a frequent mantra in the book, i.e., Think Global, Act Local, a phrase first coined by Patrick Geddes, the father of British town planning, over a 100 years ago (Stephen, 2004). A good message to end on!

Critical Care Medicine www.ccmjournal.org e77 importance of each of these mechanisms likely varies depending on different disease phenotypes, and acuteness, extent, time course and type of gas exchange disorders (2). In particular, these data by Nori et al (1) show what we could only suggest in our recently published physiologic study (3) in Critical Care Medicine, that HFOT may reduce the rate of failure of NIV withdrawal. Worth remarking, they also confirm that around one third of COPD patients requires NIV resumption after attempting withdrawal. The potentials of HFOT in the management of patients with hypercapnic ARF are not limited to this specific condition. A recent pilot study indicates a role for HFOT in alternative to standard oxygen during breaks off NIV (4). In fact, compared with standard oxygen, HFOT was more comfortable and did not result in any increase in respiratory rate and dyspnea, as observed with standard oxygen. Finally, HFOT might play a role in the treatment of the mildest forms of hypercapnic ARF, in alternative to NIV (5). Dr. Pisani received funding from Chiesi and AIM ITALY SRL.

That Lewis Carroll's Alice in Wonderland and Through the Looking-Glass have inspired an ever-vibrant range of responses is perhaps not so very curious. These classic texts upset some of the central tenets of mainstream narrative conventions not to mention, of course, the tradition of morally didactic children's narratives to which they could be seen as a reaction. Carroll's disruption of the continuity and causality on which many fictional representations and philosophical conceptions of identity and reality have tended to rely has made his work the focus of much literary and philosophical inquiry. Around sixty adaptations, ranging from Cecil Hepworth's silent film version in 1903 through puppet versions, rap versions, and porn versions to the most recent Tim Burton film in 2010, bear witness to the continuing appreciation of Carroll's story also from the field of cultural production. In addition, intertextual references to the Alice books are ever present, far too numerous to count, and decidedly disparate including, to pick a couple of random but well appreciated examples, Jefferson Airplane's psychedelic 1967 rock song "White Rabbit" and the Wachowski brothers' postmodern The Matrix (the homage of which is returned in Burton's recent film). One could imagine a point of exhaustion with this trope and with the interpretative possibilities it can yield but this seems to be far from the case. Instead, the Alice phenomenon has reached


Abstract : The long-term goal of this research is to develop a systematic approach to understanding acoustic uncertainty as it pertains to the passive sonar system. The approach combines measurements and modeling, and has been broken into three stages: quantifying, predicting and exploiting uncertainty. This requires an understanding of the environmental drivers of acoustic uncertainty (oceanographic, geoacoustic and bathymetric variability). To this end OASIS has conducted and will continue to study the results of acoustic transmission and ambient noise measurements in the Southern East China Sea (SECS) during two joint field studies with Taiwanese and US collaborators. The first, a pilot study, was completed in September, 2008, and the second, an Intensive Observation Period (IOP), was just completed in August and September of 2009. The acoustic measurements focused primarily on quantifying the major physical mechanisms giving rise to uncertainty in the acoustic data. Candidates evaluated included ocean mesoscale effects due to the Kuroshio Intrusion and frontal structures such as the Cold Dome, effects due to internal waves and internal tides, and spatial variability in the sea-bed and the sea surface.

SVO is actually a derivation of the base- generated SOV,motivated by Checking Theory.In English the checking process is triggered by the uninterpreted features,while in Chinese the process is motivated by the functional T.When T is strong,the verb is absorbed to the to have its features checked and SVO is derived;while SOV survives as T is weak and not strong enough to absorb the verb to the position.T has to be lowered to merge with the verb and the appearance of a tense auxiliary is obligatory.

Its objective is to identify the principal obstacles children and young people face with regard to the realisation of their rights under the Convention on the Rights of the Child.


This study develops a ferrofluid-lubricated thrust bearing with an air cushion. The bearing comprises a rotor, a stator, and a ferrofluid ring formed between them due to absorption by an annular magnet under the stator. The design makes it possible for the air cushion (air sealed inside the ferrofluid ring) as well as the magnetized ferrofluid to supply supporting forces. A model of the bearing for a static supporting force is proposed and validated by experiments. As the gap between the rotor and stator was 0.25 mm, the maximum static supporting force of the bearing was 3.2 N, much higher than the support provided by the pure ferrofluid ring (without the air cushion, 1.7 N). The operating space of the bearing was detected by multicycle load–retract tests with remarkably high and repeatable accuracy. The results of dynamic experiments show that the speed of rotation of the rotor has a minor effect on the supporting force. Such a ferrofluid-lubricated bearing offers promise for use in precise positioning or low-friction systems.


ABSTRACT The purposes of this study were to determine the effects of Minicourse 18 on the development of 27 specific teacher behaviors related to teaching reading decoding skills by a grcup of inservice and preservice teachers of primary grade children, and to determine the effects of the teacher training upon pupil 1:erformance in reading. Minicourse 18 was designed by the Far West Laboratcry for Educational Research and Development to improve teacher effectiveness in aiding children in their acquisition of reading decoding skills. Fourteen inservice teachers and nineteen preservice teachers served as subjects. Seven inservice teachers and nine preservice teachers were trained with Minicourse 18, and the remaining seventeen subjects served as a control group. All of the subjects taught a twentyto thirty-minute lesson on reading decoding skills to three pupils one week before and two weeks after the training of treatment panel teachers. Some of the findings indicated that training with Minicourse 18 contributed significantly to the development and refinement of behaviors related to teaching reading decoding skills. Also, training with Minicourse 18 appeared to have provided teachers with a more systematic approach to teaching reading decoding skills.


We describe the Joint Effort-Topic (JET) model and the Author Joint Effort-Topic (aJET) model that estimate the effort required for users to contribute on different topics. We propose to learn word-level effort taking into account term preference over time and use it to set the priors of our models. Since there is no gold standard which can be easily built, we evaluate them by measuring their abilities to validate expected behaviours such as correlations between user contributions and the associated effort.


Bariatric surgery can be an effective therapy for weight loss in those who are obese. The American Diabetes Association (2015) reviewed the current available studies and recommendations regarding bariatric surgery and diabetes. For those with diabetes, an additional positive effect of bariatric surgery can be an improvement in blood sugar control. Seventy-two percent of patients achieve complete normalization of blood sugar 2 years following surgery. This compares to 16% of patients treated medically with lifestyle changes and medications. Characteristics that predict success include younger age, shorter duration of Type 2 diabetes, lower A1c, higher serum insulin levels, and nonuse of insulin. There are several types of bariatric surgery to understand (1) gastric bypass surgery, (2) laparoscopic gastric binding, and (3) sleeve gastrectomy. Gastric bypass surgery is a permanent change that shrinks the stomach and shortens the path that food takes as it travels through the small intestine. The number of calories absorbed is then limited. Laparoscopic gastric binding (lap-banding) consists of a belt wrapped around the stomach so the patient will feel full with less food. The banding can be adjusted or reversed. In sleeve gastrectomy, 80% of the stomach is removed. Sleeve gastrectomy has become the most popular weight loss surgery in the United States, accounting for 42.1% of the 179,000 procedures in the last year ("Remission rates," 2014). Disadvantages of the procedures include cost and risk. Although the 30-day mortality rates have decreased to 0.28%, outcomes vary based on the procedure, experience of the surgeon, and the center. Safety improvements are primarily


This paper analyzes the changes that have taken place in university management, based on a type of university that is complex, not for profit, with a public service vocation and an emphasis on research. The first part addresses the issue of university organization, particularly profit viewed as an element to be kept in mind in defining a management model. It then goes on to describe two processes that cut across any organization: strategic planning, which sets out the major lines for institutional development and the subject of university government, i.e. the structure that shapes the decision-making process and that makes it possible to define the proper course for the plan. The second part of the text analyzes the reactions of the university to the new trends and challenges which, essentially, determine management with a view to delivering adequate responses to the requirements posed by a diverse and changing environment.


This study investigates the detection problem of multiple moving targets using a multisite radar system with widely separated stations. Spatial mapping is presented to integrate the observation data of a moving target from different angles into a spatial resolution cell (SRC). However, data association errors occur in some SRCs in this way, which causes extra false alarm, called the "ghost target". Therefore, an interference discriminator-based detector is developed. In this way, the background interference is discriminated between "ghost target" and pure noise, and then the final decision is made based on the generalized likelihood ratio test. Statistical analyses are provided to discuss the achievable performance. Simulation results show that the proposed algorithm can accurately detect multiple moving targets while suppressing the "ghost target".


The history of humanity continues to be shaped by the innovations and changes, in addition to the legacy of the past. This situation also shows itself in old age, a stage of human life. Old age can be defined as a period that gains biological, psychological and sociological dimensions in parallel with the advancement of chronological age. Since the beginning of history, the aging process and struggles to overcome death have been involved in myths which is one of the most important combinations of people's oral history. This study discusses the implications of gerontology based on the imaginative horizons of ancient Greek mythology. In the study, the relationship between gerontology and mythology is examined through Greek mythology. Analyzes on mythological references, stories and gods about old age was made. These mythological narratives still shed light on understanding the phenomenon of old age.


I do problem-based research because it helps me answer the ''who cares'' question, generate novel theoretical insights, and provide a window for practical change. Of course, I am not alone in believing that the communication discipline could be enhanced through a focus on problems and in situ communication. I am thankful that my training at the University of Colorado included a problem-based approach, and fortunate to be surrounded with colleagues at Arizona State University who examine communication dilemmas and encourage innovative problem-based research approaches. Indeed, the need for our scholarship to make a difference is nothing new. More than a decade ago, Craig and Tracy (1995) encouraged scholars to theorize in ways that address ''actual problems and requirements of communicative praxis in particular settings'' (p. 249). In Making Social Science Matter, Flyvbjerg (2001) delineated a lucid explanation of ''phronetic research,'' the task of which is ''to clarify and deliberate about the problems and risks we face and to outline how things may be done differently, in full knowledge that we cannot find ultimate answers to these questions or even a single version of what the questions are'' (p. 140). In his presidential address at the 2002 National Communication Association convention, James Applegate urged communication scholars to engage in the kind of use-inspired basic research (Stokes, 1999) that would solve problems and improve lives. So, why do we continue to have forums like this? Perhaps a problem with fulfilling the call for theorizing communication problems is that people need more information about the challenges of doing problem-based research. In this forum I draw from my past qualitative organizational communication scholarship to discuss several methodological and epistemological issues that have been particularly


Hydrogen sulfide (H2S) has been known for decades as a toxic gas. However, this gas has been discovered to be synthesised enzymatically in human tissues and is regarded as a novel gasotransmitter. H2S is a signaling molecule that involves and governs many biological functions of the body. It has been shown that H2S is associated with various disease conditions such as acute pancreatitis, sepsis, inflammation and atherosclerosis development. Current therapeutic approach may not benefit all patients with atherosclerosis. Therefore, the role of H2S as an anti-atherosclerotic agent has been the spotlight of cardiovascular medicine. Moreover, its implications in other diseases have also been studied extensively in order to develop new therapeutic approaches.


This report considers combining information to improve retrieval. The vector space model has been extended so different classes of data are associated with distinct concept types and their respective subvectors. Two collections with multiple concept types are described, ISI-1460 and CACM-3204. Experiments indicate that regression methods can help predict relevance, given query-document similarity values for each concept type. After sampling and transformation of data, the coefficient of determination for the best model was .48 (.66) for ISI (CACM). Average precision for the two collections was 11% (31%) better for probabilistic feedback with all types versus with terms only. These findings may be of particular interest to designers of document retrieval or hypertext systems since the role of links is shown to be especially beneficial.


The study of literary texts is one of the earliest disciplines practiced around the globe. Poetry is artistic writing in which words are carefully chosen and arranged for their meaning, sound, and rhythm. Poetry usually has a broad and profound sense that makes it difficult to be interpreted even by humans. The essence of poetry is Rasa, which signifies mood or emotion. In this paper, we propose a poetry classification‐based approach to automatically extract similar poems from a repository. Specifically, we perform a novel Rasa‐based classification of Hindi poetry. For the task, we primarily used lexical features in a bag‐of‐words model trained using the support vector machine classifier. In the model, we employed Hindi WordNet, Latent Semantic Indexing, and Word2Vec‐based neural word embedding. To extract the rich feature vectors, we prepared a repository containing 37 717 poems collected from various sources. We evaluated the performance of the system on a manually constructed dataset containing 945 Hindi poems. Experimental results demonstrated that the proposed model attained satisfactory performance.


By 2004 according to the resuts of the international genome sequencing, about 20,000 protein-coding genes had been analyzed which correspond to more than 2% of the total genomic sequence. The vast majority of gene transcripts are actually characterized as non-coding RNA (ncRNA) and are a cluster of RNA that do not encode functional proteins. They can be small, approximately 20 nucleotides in length, known as microRNAs (miRNAs), or transcripts longer than 200 nucleotides, defined as long non-coding RNAs (lncRNAs). miRNAs are short ncRNAs that are involved in the post-transcriptional regulation of gene expression. Discovered over 15 years ago, these molecules have been recognized as one of the main regulatory molecules in the human genome. They play an important role in all biological processes being important modulators of the eukaryotic genes expression. Focusing on transcripts that encode proteins, miRNAs influence the cellular transcript, thereby helping to determine the outcome of the cell. Aberrant miRNA expression was observed in cancer patients. Tissue concentrations of specific miRNAs have been shown to be associated with tumor invasiveness, metastatic potential, and other clinical characteristics for many types of cancer. Compared to traditional biomarkers like proteins, miRNA has several advantages that will allow them to be considered as new potential biomarkers in cancer. This review looks at biogenesis, functions, technologies used to detect miRNA, and the association of miRNA with human cancer, in particular, colorectal cancer.


Kids Growing with Grains is a school-based agricultural education program that improves youths' conceptual understanding of how agriculture is linked to nutrition, the environment, and human health. University of Maryland Extension Educators developed the program's hands-on activities, which focus on grain science, grains and the environment, grains and animals, and grain nutrition. The program is traditionally implemented through a station-based field trip experience lasting 4 hours in length. The program has been evaluated using a mixed-methods approach that includes qualitative and quantitative data collected from both teachers and students. Evaluation results from the past 2 years indicate the program is achieving its learning objectives. The program is designed to be easily replicated by other Extension programs throughout the country in a variety of formal or non-formal settings.


Abstract In the current era of accelerated economic growth, project success – successful completion of the final product for which the project was initiated – is the ultimate goal of every organisation. It is essential for organisations to keep project-based employees motivated and focused on successfully accomplishing the project objectives. This research examined the association between psychological empowerment of project-based employees and project success. We explored the mediating role of knowledge sharing to explain the intervening mechanism between psychological empowerment and project success. We also tested the moderating role of employee creativity along with conditional indirect effects by performing a moderated mediation analysis. Using a time-lagged research design, multiple-source field data (N = 327) were collected from employees of project-based organisations in Pakistan. The findings of the study showed a positive association between psychological empowerment and project success and significant mediation of knowledge sharing. Project employees with high creativity are likely to achieve project success when they possess higher psychological empowerment too. Results concluded that psychological empowerment is positively associated with project success directly as well as indirectly through its impact on knowledge sharing. The study has its importance and implications for management specialists and project employees at all levels.

The Philippine sports culture is embedded in its communities as they are aggressively engaging in sports initiatives involving the youth from grade school to college levels capturing the passion of the sport's participants at the grassroots level. Varsity players were exposed to such passion which shaped their competence in sports and physical activity later in life. This research analyzed the motivation and attitudes of the varsity athletes in higher education who have been participating in community sports in their growing years. Ninety (n = 90) varsity players from three state universities and colleges in Zamboanga City, Philippines participated in a Likert-scale survey to determine their level of motivation and attitudes towards community sports initiatives in relation to their athletic participation in the university. Findings revealed that the level of motivation among varsity students for the benefits of sports was very high and their gender and years of being a varsity player. Attitude indicators also revealed that varsity players pursue sports because it develops their competence and social skills. Community sports initiatives promoted a competitive mindset, as well as boosted confidence as players were able to prepare for competitions. This study is important for government and universities to consider the role of community sports initiatives in developing their long-term grassroots sports programs.


[Objective] To evaluate in vitro the microtensile bond strength of four adhesives to enamel and dentine . [Method] A total of 40 intact young human premolars extracted for orthodontic reasons were randomly divided into 8 groups of 10 teeth. Four adhesives: two self-etching adhesives (A: Adper Prompt, B: Xeno Ⅲ) and two total-etching adhesives (C: Single Bond 2, D: Prime Bond: NT). The following experimental groups were then formed: enamel groups: AE, BE, CE, DE and dental groups: AD, BD, CD, DD. A block of composite resin was bonded respectively with four adhesive systems according to manufacture′ instructions. Each tooth yielded 2 sticks about 1.5 mm2 in cross-sectional area for microtensile testing. Specimens were loaded in tension at a crosshead speed of 1.0 mm/min, and bond strength at failure was calculated in mPa. ANOVA was applied to test for significantly of the groups. [Results] On group enamel, ANOVA demonstrated there were significant difference in the bond strength (P 0.05). The bond strength values of group BE was significantly higher than those of the test products. Date were analyzed using SNK method: there was significant difference between the bond strength of group BE and group DE (P 0.05) and there was no significant difference in the other groups (P 0.05). Among groups dentin: statistical analysis of the date showed no significant difference (P 0.05). [Conclusions] The microtensil bond strengths of four adhesives to normal enamel are different and the self-etching adhesive Xeno Ⅲ exhibited the greatest bond strength. Comparing the microtensil bond strengths to dentine, one-step self-etching adhesives are similar to that of the total-etching adhesives.

Tissue engineering has the potential for repairing large bone defects, which impose a heavy financial burden on the public health. However, difficulties with O2 delivery to the cells residing in the interior of tissue engineering scaffolds make it challenging to grow artificial tissues of clinically-relevant sizes. This study uses image-based simulation in order to provide insight into how to better optimize the scaffold manufacturing parameters, and the culturing conditions, in order to resolve the O2 bottleneck. To do this, high resolution 3D X-ray images of two common scaffold types (salt leached foam and non-woven fiber mesh) are fed into Lattice Boltzmann Method fluid dynamics and reactive Lagrangian Scalar Tracking mass transfer solvers. The obtained findings indicate that the scaffolds should have maximal surface area-to-solid volume ratios for higher chances of the molecular collisions with the cells. Furthermore, the cell culture media should be flown through the scaffold pores as fast as practically possible (without detaching or killing the cells). Finally, we have provided a parametric sweep that maps how the molecular transport within the scaffolds is affected by variations in rates of O2 consumption by the cells. Ultimately, the results of this study are expected to benefit the computer-assisted design of tissue engineering scaffolds and culturing experiments.


This paper describes a general model for the mechanical behavior studying of general wire rope strand. An exact solution of the deformation characteristics was given when the strands is under tensile and torsional loads. The theoretical results are useful in evaluating the extensional and torsional moduli of rigidity for the strands. Finally, a simple design criterion is established for the nonrotating ropes.


In this paper, a new correlation for prediction of the ratio of critical temperature to critical pressure has been developed in terms of heat capacity at 298.15 K, which is readily available for many compounds. The correlation has been applied for more than 100 low to medium size compounds. The results of these estimations validate the generalization of this correlation. The comparison between predicted and available experimental data shows an absolute relative error of 4.69 %. The results show that the accuracy of the proposed correlation is similar to the methods of Constantinou and Gani,(7) Ambrose,(2, 3) and Joback(5) for various types of compounds.


Visual communication can enhance understanding, recall, attention, and also collaboration by visualizing a group's discourse. The object of inquiry of this work is how teams communicate and collaborate with the help of (evolving) visual artefacts that act as versatile communication catalysts and that make knowledge explicit. Although several authors have described which characteristics should be enhanced to improve visual representations, there is as yet scarce understanding as to the optimal level of these characteristics for specific purposes. In this contribution we propose a framework based on the approach of so-called 'cognitive dimensions of notations'. We develop this approach further and propose a collaborative dimensions of visualization framework, which allows us to distinguish different traits of visual artefacts with regard to their effects on team communication and collaboration. The seven dimensions are described, and illustrative examples of application to group communication are provided.


In this paper, we examine the financial and real effects of macroprudential policies with a new identifying strategy that exploits borrower-specific provisioning levels for each bank. Locally, we compare similar firms just below and above regulatory thresholds established in Colombia during 2008--2018 for the corporate credit portfolio. Our results indicate that the scheme induces banks to increase the provisioning cost of downgraded loans. This implies that, for loans with similar risk but with a discontinuously lower rating, banks offer a lower amount of credit, demand higher quality guarantees, and impose a higher level of provision coverage through the loan-loss given default. To illustrate, a 1 percentage point (pp) increase in the provision-to-credit ratio leads to a reduction in credit growth of up to 15pp and lowers the probability of receiving new credit by up to 11pp. When mapping our results to the real sector, we find that downgraded firms are constrained in their investment decisions and experience a contraction in liabilities, equity, and total assets.

Mehedi Hasan Scaling of transistors (the building blocks of modern information age) provides faster computation at the expense of excessive power dissipation. Thus to address these challenges, high-k/metal gate stack has been introduced in commercially available microprocessors from 2007. Since then titanium nitride (TiN) metal gate's work function (Wf) tunability with its thickness (thickness increases, work function increases) is a well known phenomenon. Many hypotheses have been made over the years which include but not limited to: trap charge and metal gate nucleation, nitrogen concentration, microstructure agglomeration and global stress, metal oxide formation, and interfacial oxide thickness. However, clear contradictions exist in these assumptions. Also, nearly all these reports skipped a comprehensive approach to explain this complex paradigm. Therefore, in this work we first show a comprehensive physical investigation using transmission electron microcopy/electron energy loss spectroscopy (TEM/EELS), x-ray diffraction (XRD), x-ray photoelectron spectroscopy (XPS) and secondary ion mass spectroscopy (SIMS) to show replacement of oxygen by nitrogen in the metal/dielectric interface, formation of TiONx, reduction of Ti/N concentration and grain size increment happen with TiN thickness increment and thus may increase the work function. Then, using these finding, we experimentally show 100meV of work function modulation in

Objective To observe the effect of PMMA particles on the expression of RANK in rats macrophage cultured in vitro. Methods Peritoneal macrophages were obtained from the peritoneal of rats and cultured and purified in vitro.Cells purity were identified by immunocytochemistry techniques and treated with PMMA particles according to the experimental design. Semi-quantitative reverse transcription PCR method was used to detect the level of RANK mRNA. Results PMMA particles enhanced RANK mRNA expression of rats peritoneal macrophage in a time-and dose-dependent fashion.RANK mRNA expression in the peritoneal macrophage was elevated dose-dependently and time-dependently following PMMA particles treatment and reached its peak level at a concentration of 0.1‰~5‰(v/v)(P0.05),especially co-cultured for 24 h in vitro (P0.05). Conclusion By altering the relative expression of RANK mRNA,PMMA particles have the potential of facilitating macrophage transform into cells that acting as bone resorption ones.


Malaria infection is commonly associated with an increased proliferation of both blood stream and tissue phagocytes. These cells have been shown to be involved primarily in non specific defence mechanisms against parasite multiplication (Allison & Clark 1977). Secondarily they may also be involved in antibody dependent cellular cytotoxicity (Celada, Cruchard & Perrin 1983, Khusmith & Druilhe 1983). The role of spleen and liver macrophages was suggested as early as 1937 by Taliaferro and Mulligan (1937) on the basis of histopathological findings in humans and since then has been confirmed in experimental models (Shear, Nussenzweig & Bianco 1979, Brinkmann et al. 1984). More recently it has been demonstrated that the phagocytic cells may damage the intraerythrocytic parasites by their production of reactive oxygen species (ROS) which could directly act at the intraerythrocytic level on the parasite (Allison & Eugui 1982, 1983, Clark & Hunt 1983, Cox 1983, Dockrell & Playfair 1983, Ockkenhouse & Shear 1984, Wozencraft et al. 1984). Furthermore Brinkmann et al. (1984) have also shown in mice that the capacity of splenic macrophages to produce Oz-. metabolites could be related to the outcome of the disease. However most of these previous findings were obtained in experimental models in which parasite load was usually higher than that observed in human malaria. The aim of the present study was to investigate the levels of ROS production by human circulating phagocytic cells during acute and severe forms of malaria, in an attempt to determine: (1) whether these highly reactive molecules could be involved in the host defence mechanisms and (2) whether this determination could be useful in the evaluation of the severity of the disease and the observed pathological findings.


The nucleation of a lamellar phase from a supercooled homogeneous phase in a fluctuation driven first-order transition is studied, based on a phenomenological free energy due to Brazovskii. The absence of phase coexistence in the corresponding mean-field approximation makes application of the standard droplet theory of homogeneous nucleation problematic. A self-consistent coarse-graining procedure is introduced to overcome this difficulty, and the barrier height for nucleation of a critical droplet is estimated in the weak-coupling limit. Contrary to earlier estimates the critical droplet shape is shown to be anisotropic in general. Some effects of distortions and defects in the lamellar structure are considered and are shown to affect the critical droplet only very near coexistence where the probability of nucleation vanishes. The coarse-graining procedure introduced here follows from a novel application of the momentum-shell renormalization group method to systems in the Brazovskii class. Possible applications of the theory to the microphase separation transition in diblock copolymers and to Rayleigh-B´enard convection are briefly discussed.

The electron microscopic study of six cases of chronic radiodermatitis from sun‐exposed and unexposed skin, confirms the observation of elastosis previously described with light microscopy. The pathological findings are comparable with those found in actinic elastosis; increased width of the fibres, irregularity of their shape, increased density and granularity of the microfibrils and holes with many lobes in the matrix.


Aims: to evaluate the outcome following internal þxation of olecranon fractures using the techniques of tension band wiring and plating with a minimum follow up of two years. Methods:Design: retrospective evaluation and clinical review. Setting: regional trauma centre. Patients and participants: 48 consecutive patients with fractures of the olecranon were treated over a twenty month period (may 1993 to december 1994). 25 fractures were þxed using a tension band wiring technique and 23 underwent plating; the selection of method was based on agreed radiological fracture pattern criteria. Main outcome measurements: radiographic evaluation of the quality of reduction. Clinical outcome (broberg and morrey functional rating index). Results: clinical evaluation of 39 patients was carried out. In the tension band wiring group 17 (85 percent) patients had an excellent or good outcome and 11 (55 percent) patients underwent a second procedure for symptomatic metalwork. In the plating group 16 (84 percent) patients had an excellent or good outcome and 2 (11 percent) patients underwent a second procedure for symptomatic metalwork. The latter group had more complex and associated fractures and included the only poor result. Conclusion: internal þxation of fractures of the olecranon results in good functional outcome. Fixation with a plate is effective and produces good outcome even though selected for the more complex olecranon fractures. Patients who have tension band wiring more often require a second procedure for removal of symptomatic metalwork.


The more rapidly growing company in Indonesia makes a company competing on getting profits. In taking into account necessary accounting as the basis for the calculation of income and disbursements. Usually growing company working with banks, these banks function receives corporate earnings. After the company's revenue is transferred to a designated bank then deposits the company also recorded income of the company. To avoid mistakes in recording, periodically testing the truth needs to be done daily and monthly to reconcile cash records according to the company with cash records according to the bank. This process is called Reconciliation. Reconciliation was first performed in the commercial section of the match TUL V-04 with CN (credit note), aiming to ensure repayment of balance. Once reconciliation is done between the commercial with the financial section with a road match the balance TUL V-04 with newspaper accounts held by financial section. The next step is to perform reconciliation between the financial accounting section of the road match the bank's general ledger balances with bank account statements to prove the truth and book-keeping.

Background: Cardiac tamponade (CT) as the primary clinical manifestation of lymphomas is extremely rare. Angioimmunoblastic T-cell lymphoma (AILT) is characterised by systemic disease usually presenting with generalised peripheral lymphadenopathy, hepatosplenomegaly, and bone marrow infiltration. Case Report: We report on a 59-year-old male patient with CT as initial clinical manifestation of AILT. Coexistence with malignant pleural mesothelioma was additionally revealed. Cytologic examination of pericardial fluid presented diffuse lymphoid cells and sporadic malignant mesothelial cells. AILT diagnosis was confirmed by thoracoscopic mediastinal lymph node and bone marrow biopsy. Despite the presence of pleural effusion, the diagnosis of mesothelioma was initially established by cytologic ex-amination of pericardial fluid, due to the patient's critical cardiac condition requiring prompt subxiphoid pericardiocentesis. Conclusion: CT as primary clinical manifestation of AILT is very rare. This case reflects the differences in the underlying biology of AILT and consequently the vast spectrum of its clinical presentations. Coexistence of AILT with malignant pleural mesothelioma is also extremely rare.


This paper shows how it is possible to build a simple remote laboratory using just one application - Matlab. Matlab is a well-known tool in engineering education and praxis that together with Simulink serves for calculation and simulation of signal responses and system behaviors. Matlab/Simulink includes a rich set of commands and many libraries of useful blocks that allow its users to compute results from many engineering areas. The latest versions of Matlab/Simulink have also strong support for data communication. In this paper specific commands and blocks of a Matlab/Simulink library have been used to establish a connection between client and server applications both based on Matlab. Thus together with the real equipment connected to the server side it is possible to build a simple remote laboratory. Its main advantage is that it doesn't need any other technology except of Matlab/Simulink that is familiar for both students and teachers. The design of a simple remote laboratory is demonstrated on the example of a thermo-optical system.


Primary neoplasms of the facial nerve may develop at any location, from the cerebellopontine angle to the facial musculature. Histologically, these uncommon lesions are primarily classified as schwannomas, neurofibromas, or malignant schwannomas. The majority originate from Schwann cells. Rarely, neurofibromas may demonstrate a malignant potential; this is primarily seen in individuals with neurofibromatosis. Approximately 300 cases have been reported thus far in the literature as a result of significant advances in diagnosis. The purpose of this article is to review tumors arising on the facial nerve, proximal to the stylomastoid foramen, which were encountered in our neurotologic practice. We focus on current diagnostic and therapeutic problems and solutions relative to the topic.


This paper makes two contributions. First, we provide a review of the similarities and difference between Generalized Method of Moments and Indirect Inference, focusing particularly on issues of moment selection, identification failure and model misspecification. Secondly, we provide new results on the limiting behaviour of GMM and II estimators when first order identification fails but the parameters are second order identified.


The possibility of the direct current use in the enterprise intra shop power supply systems for the electric power loss reduction purpose, the power supply reliability and the electromagnetic compatibility problem solution is considered. The structural direct current micro network scheme on the basis of own need generators, equipping gas-distributing units for gas-compressor workshop electrical generating system, is suggested. The use of these generators at changeable shaft speed is analyzed, with a possibility of regulation of gas-distributing unit capacity for the transporting gas optimization mode. The own need generators combination in the micro network for the purpose of energy surplus use for the gas air coolers power supply is essential.

Abstract : Tests conducted since the first interim report have emphasized the characterization of the elements of the correlator/convolver, rather than the performance of the complete device. Prior work having vindicated the choice of the four transistor bridge configuration, the present interim period focused on the adequacy of the floating gate and source followers as designed. An extensive characterization of the floating-gate-output CCD test pattern was carried out. Maximum signal swing, linearity and noise level were measured with four different input techniques. All results were as good or better than expected. Accuracy of about one percent could be maintained over a signal range of about 4.25 volts. Surprisingly, the potential equilibration techniques gave linearity at least as good as that obtained with the diode-cutoff method. However, the potential equilibration input was up to 15 dB quieter. The signal to noise ratio referenced to the 1% nonlinearity signal level was approximately 80 dB, 10 dB better than the design goal. With the additional 6 dB enhancement of signal over noise of the bridge multiplier as compared to conventional multiplier designs, a net effective input signal to noise ratio of about 85 dB is expected in the complete correlator/convolver. Finally, the design of the deliverable 256-stage correlator was completed and entered into the maskmaking CAD system. The problem reported earlier with direct feedthrough of the drain inputs was found to be due to a difference in characteristics between transistors located under one and under two layers of polysilicon and will be corrected in this final design.


Based on the NCEP daily reanalysis data and the conventional surface observations in the middle and eastern part of Sichuan Province,an analysis of gravity waves and wet vorticity during the rainstorm on July 31,2009 was carried out.As the motion in the atmosphere without diabatic heating and frictional dissipation conserves moist potential vorticity,it is showed that the moist potential vorticity distribution and temporal change was closely related to the development of the heavy rainfall.The divergence fields and diagnostic results of the non-linear balance equation showed that the gravity wave characteristics had a very significant change during heavy rainfall.The atmospheric instability not only is the excitation source of heavy rain,but also generates gravity waves,so moist potential vorticity and gravity waves play a good role in the forecast of the heavy rainfall.


Rational Use of Diagnostic Procedures in Inflammatory Bowel Diseases The diagnostics of chronic inflammatory bowel diseases is based on patient's history, clinical findings, selected laboratory tests, and endoscopy plus histology. Making a diagnosis means to consider the results of various diagnostic procedures. Ileocolonoscopy is very important for establishing the initial diagnosis. The small bowel should be visualized as well (enteroclysis or MRI), in order to detect or to exclude Crohn's disease of the small bowel. During the follow-up, important information is provided by clinical examinations, laboratory tests and transabdominal ultrasound. Endoscopy is indicated when symptoms change, when complications occur or when important new therapeutic decisions have to be made (e.g. surgical resection). In patients with extensive ulcerative colitis, screening colonoscopies with multiple biopsies should be started after 8 years and performed every year. In Crohn's disease no guidelines for cancer screening exist.


OBJECTIVE: To assess the social support and household disaster evacuation readiness among flood-affected households in a rural village of Tamil Nadu. METHODS: We conducted this cross-sectional analytical study in the flood-affected Koonimedu village of Villupuram District, Tamil Nadu, 8 months after the flood. One adult member (age >18 years) from each of the flood-affected households was included and interviewed face to face at his/her house. Information on sociodemographic details, loss of property, and household evacuation readiness plan was obtained using a semistructured pretested questionnaire. Social support was measured using the Crisis Support Scale (CSS). RESULTS: Nearly 60% of the households were still waiting for government assistance for house repair. Less than a quarter of households reported adequate social support. Availability of people to listen to them, able to discuss their thoughts and feelings, and contact with people in similar situations showed improvement after 8 months of flood. CSS score on feeling letdown showed a significant increase 8 months after the flood. Although all the households were ready to evacuate if flood recurs, none have undergone training on disaster preparedness. Majority of the households reported to secure ration card first during evacuation. CONCLUSION: The level of adequate social support during flood as well as 8 months after the flood was low among the study population. Although all households have their own disaster evacuation plan, none have been given information and training on disaster preparedness.


In this brief, robust trajectory tracking control problem for quadrotors is investigated to improve the tracking performance of the closed-loop control system subject to parametric uncertainties, non-linearity and coupling, unmodelled dynamics, and external disturbances. The vertical, lateral, longitudinal and yaw motions of the vehicle are required to be controlled along desired trajectories simultaneously. The proposed linear-decentralised controller consists of three parts: an observer to estimate the linear velocities, which cannot be measured directly, a position controller to achieve the trajectory tracking and produce the desired references for the pitch and roll angles, and an attitude controller to stabilise the attitude angles. The robustness properties of the whole uncertain closed-loop control system are proven. Experimental results are given to demonstrate the effectiveness of the proposed closed-loop control system.

In the peak period of construction on busy roads, suggest transport dispersion scheme and submit the scheme to the proprietor; (2) keep the carriages carrying spoil earth and building materials complete. In loading, the carriage shouldn't be too full; (3) the construction process, maintenance of the equipment should be carried out frequently; (4) construct respectively the rainwater guidance canal and filtering and sedimentation basin within the construction scope; and (5) carry out recycle of solid waste resource.


This paper reports the Suzaku results on the northeast shell of RCW 86. With the spatial and spectral analysis, we separated the X-rays into three distinct components; low (kT_e~0.3keV) and high (kT_e~1.8keV) temperature plasmas and a non-thermal component, and discovered their spatial distributions are different from each other. The low temperature plasma is dominated at the east rim, whereas the non-thermal emission is the brightest at the northeast rim which is spatially connected from the east rim. The high temperature plasma, found to contain the ~6.42keV line (K alpha of low-ionized iron), is enhanced at the inward region with respect to the east rim and has no spatial correlation with the non-thermal X-ray (the northeast). The Fe-Kalpha line, therefore, is not related to the non-thermal emission but originates from Fe-rich ejecta heated to the high temperatures by the reverse shock. Since the metal abundances of the low temperature plasma are sub-solar, the most possible origin of this component is interstellar medium heated by a blast wave. The non-thermal X-ray, which has a power-law index of ~2.8, is likely to be synchrotron emission. A possible scenario to explain these morphologies and spectra is: A fast moving blast wave in a thin cavity of OB association collided with a dense interstellar medium or cloud at the east region very recently. As the result, the reverse shock in this interior decelerated, and arrived at the Fe-rich region of the ejecta and heated it. In the northeast rim, on the other hand, the blast wave is still moving fast, and accelerated high energy electrons to emit synchrotron X-rays.


Fast developing network puts forward more complex requirements for detecting traffic abnormal behavior, but many existing methods cannot effectively curb the harm of botnet. This paper proposed a botnet detection method based on multidimensional permutation entropy and clustering variance. According to the traffic characteristics in the propagation period of bots, we used multidimensional permutation entropy to calculate the complexity of time series of network traffic, and then used cluster variance to detect the self similarity of permutation entropy model, finally the results proved the validity of this method. This method is based on the general characteristics of botnet, so we can detect all known and unknown botnets.

A vehicle includes a power feeding inverter that converts at least one of power discharged by a storage apparatus and power generated by activating an engine into alternating current power. The vehicle detects the presence of a user within a predetermined range of the vehicle using at least one of a seat occupancy sensor, a camera provided on the exterior or in the interior of the vehicle, and a reception unit that receives ratio waves from a smart key. When a request for power feeding from the vehicle is issued but the user has not been detected within the predetermined range of the vehicle, power generation by activating the engine is prohibited.


Ultralow vibration environments are required for detectors that will form a worldwide array of gravitational observatories. At the University of Western Australia and in collaboration with BHP Engineering, we are developing high performance vibration isolators which utilise ultra sensitive microwave position transducers and active control systems to achieve vibration levels which must approach 10-20 ml[mega]Hz for frequencies above 100 Hz. In this paper we report developments in the following areas: 1. Sapphire microwave position transducers sensitive to displacements of 10-14 m at room temperature. 2. All metal, multimode vibration isolators capable of operation at low temperatures and in high vacuum. 3. Active control systems and passive magnetic damping systems capable of reducing the amplitudes of low damped metal isolator normal modes.


Special neural accelerators are an appealing hardware platform for machine learning systems because they provide both high performance and energy efficiency. Although various neural accelerators have recently been introduced, they are difficult to adapt to embedded platforms because current neural accelerators require high memory capacity and bandwidth for the fast preparation of synaptic weights. Embedded platforms are often unable to meet these memory requirements because of their limited resources. In FPGA-based IoT (internet of things) systems, the problem becomes even worse since computation units generated from logic blocks cannot be fully utilized due to the small size of block memory. In order to overcome this problem, we propose a novel dual-track quantization technique to reduce synaptic weight width based on the magnitude of the value while minimizing accuracy loss. In this value-adaptive technique, large and small value weights are quantized differently. In this paper, we present a fully automatic framework called NN Compactor that generates a compact neural accelerator by minimizing the memory requirements of synaptic weights through dual-track quantization and minimizing the logic requirements of PUs with minimum recognition accuracy loss. For the three widely used datasets of MNIST, CNAE-9, and Forest, experimental results demonstrate that our compact neural accelerator achieves an average performance improvement of 6.4χ over a baseline embedded system using minimal resources with minimal accuracy loss.


Because of funding shortages, the Georgia Department of Transportation (GDOT), like most of its counterparts, is actively searching for improved and innovative pavement preservation methods that can help stretch limited funding to preserve its deteriorating pavements. In 2007, GDOT developed a new pavement preservation method (using micro-milling in conjunction with a thin overly) that can cost-effectively replace only the deteriorated thin open-graded top surface layer (3/4" to 8/7") without removing the large sound underlying layer. GDOT, working with Georgia Tech, has developed processes, including a Ridge-to-Valley Depth (RVD) indicator (for characterizing the micro-milled surface texture) and quality control/acceptance process, to successfully implement the new method on two large-scale projects (80 lane-miles on I-75 near Perry and 96 lane-miles on I-95 near Savannah). The new RVD indicator and its measures on these two projects were presented in earlier papers; however, the total experience of implementing these two projects has not been comprehensively presented, especially the construction processes and their quality controls. This paper presents the development of the new method, including the challenges, the construction steps, the experiences learnt during the course of the projects, and the recommendations based on the projects' results and experiences. The new method has produced satisfactory pavement performance. According to the pavement condition evaluation performed by GDOT, the pavements on the I-75 and I-95 projects are still in good condition after 7 and 3 years, respectively. The average saving is approximately $59,000 per lane-mile, and the total savings on both projects is more than $10 million, which is significant when compared to traditional pavement resurfacing method. The long-term performance monitoring on these two projects is currently underway, and their long-term cost-effectiveness will be analyzed.

"comrade" (shen-tu . . . t'ung chih, see T'ai-p'ing T'ien-kuo shih-shih-k'ao [Peking, 1955], p. 5). Lo, however, says that he is not in full agreement with some earlier Russian writers, whom he quotes, on detailed interpretations. Their belief that a class struggle emerged within the Taiping leadership and that the killing of Yang Hsiu-ch'ing was a class attack by bourgeois-feudal elements against the main peasant leader of the movement is denied by Lo (pp. 306 ff.), but is also no longer the view presented in the later Soviet Encyclopedia articles mentioned above. Lo's "independence" is therefore not heretic. Lo also reports a discussion between him and a Russian Taiping scholar, Efimov, concerning the correct interpretation of the Taiping story (pp. 341 ff.). Efimov repeats the Soviet doctrine that the Taipings represented a peasant rebellion, anti-imperialist and anti-feudal in character; he declares that the Western bourgeois scholars, who allegedly regard the Taiping Rebellion only as a religious movement, are wrong. With this Lo agrees. The discussion takes up a comparison between the importation of opium and of religion—opium for the people—by the Western powers into China. The import of opium, regarded as the main economic aspect of imperialist attack, resulted in awakening the Chinese people against imperialism. The import of foreign religion also had the result of engendering an ideology that stood up against the attack of cultural imperialism. This formula of comparison is then used to indicate how culturally and economically the Taiping uprising represented a national reaction against foreign aggression. Lo adds to this discussion his own belief that the Taiping leaders remained true to their principles to the bitter end, that Hung Hsiu-ch'iian in fact was a highly moral person, and that, though the Taiping leaders perished, they established a nationalist tradition which was later to succeed.


Efficient and compact representation of images is a fundamental problem in computer vision. Principal Component Analysis (PCA) has been widely used for image representation and has been successfully applied to many computer vision algorithms. In this paper, we propose a method that uses Haar-like binary box functions to span a subspace which approximates the PCA subspace. The proposed method can perform vector dot product very efficiently using integral image. We also show that B-PCA base vectors are nearly orthogonal to each other. As a result, in the non-orthogonal vector decomposition process, the expensive pseudo-inverse projection operator can be approximated by the direct dot product without causing significant distance distortion. Experiments on real image datasets show that B-PCA has comparable performance to PCA in image reconstruction and recognition tasks with significant speed improvement.


A comparative study of data provided by coronaro-angiography and myocardial perfusion scintigraphy (resting and exercise tests), and clinical/electrocardiographic results of the exercise test in 102 chronic coronary patients demonstrated that non-invasive myocardial perfusion 201Tl scintigraphy combined with threshold bicycle-ergometric exercise adds considerably to the clinico-electrocardiographic assessment of the exercise test and thus helps to detect myocardial blood supply (perfusion) disorders in some of coronary patients with doubtful or negative test results. Reduced functional reserves of myocardial blood supply, as reflected in deficient perfusion at the peak of threshold exercise, are seen in all coronary patients with angiographically intact coronary arteries and in most patients with both the so-called "functionally-insignificant" and marked coronary arterial stenosis (94.7 and 88.3%, respectively).

In this study, various efforts and difficulties to enlarge the supply of Hanok was described, and especially the recent research trends in the field of structure was introduced. Though, the research on the new-styled Hanok is still in the early stage, researches in the field of structure are performed actively nowadays. In structural check of Hanok, checks on vertical loading can be without difficulties, but, checks on the lateral loading is not easy because the rotational stiffness of connections must be known in advance. Researches on the structure of Hanok needs much to be done, so it is needed that researchers on the field of structure to participate in these research fields.


In 2022, we are celebrating the 85th birthday of outstanding choreographer Ashot Asaturyan. The choreographer died as many as 23 years ago, but judging from the videos of his ballets, we can say that his creative mentality and methods of musical and literary interpretation are still progressive and timely. One more peculiarity of Asaturyan's method is visualization of polyphonic principles. While in Theme and Variation, a ballet created to the music of the Finale of Pyotr Tchaikovsky's 3rd Orchestral Suite, those principles have an immanently choreographic function, in some other ballets, they are of dramaturgical significance. The common feature of the three ballets analyzed in this article is the polyphonic nature of their scenarios. Those ballets are Maurice Ravel's Daphnis and Chloe, Igor Stravinsky's Orpheus and Sergei Rachmaninoff's Symphonic Dances.


A number of big intermittent aftershocks often follow a great earthquake. Even if a building could avoid collapse by the first main quake, there would be no guarantee that the building can survive from the aftershocks. However, if it is possible to monitor the condition of the building constantly using some faint random vibration caused by environmental noise such as wind, weak earthquakes, and traffic noise, the safety of the victims should be more secured. In a field of machinery diagnostics, although several diagnostic methods using vibration based on environmental noise have been proposed, those methods require that the characteristics of the noise are known since the resonance of the object is shadowed by the environmental noise spectrum. The author has proposed an emphasizing method of hidden resonances in a time-invariant transfer function and has also applied the method to structural health monitoring by analyzing faint random vibration caused by environmental noise. This report presents the resul...


Tomato chlorosis virus (ToCV) is a serious, emerging tomato pathogen that has a significant impact on the quality and quantity of tomato production worldwide. Detecting ToCV via means of spectral measurements in an early pre-symptomatic stage offers an alternative to the existing laboratory methods, leading to better disease management in the field. In this study, leaf spectra from healthy and diseased leaves were measured with a spectrometer. The diseased leaves were subjected to RT-qPCR for the detection and quantification of the titer of ToCV. Neighborhood component analysis (NCA) algorithm was employed for the feature selection of the effective wavelengths and the most important vegetation indices out of the 24 that were tested. Two machine learning methods, namely XY-fusion network (XY-F) and multilayer perceptron with automated relevance determination (MLP–ARD), were employed for the estimation of the disease existence and viral load in the tomato leaves. The results showed that before outlier elimination, the MLP–ARD classifier generally outperformed the XY-F network with an overall accuracy of 92.1% against 88.3% for the XY-F. Outlier elimination contributed to the performance of the classifiers as the overall accuracy for both XY-F and MLP–ARD reached 100%.


This report provides a brief outline of the existing literature on the engineering properties of tropical residual soils and has laid stress on certain areas of importance and mentioned the difficulties involved in studying their properties. Guided by the available literature in this area and the papers presented to this session, the following points are suggested for discussion: (1) means of improving the conventional laboratory tests which underestimate strength properties of soils in comparison to in-situ tests; (2) methods of undisturbed sampling to determine strength and compressibility characteristics; (3) development of effective stress concept for partly saturated tropical residual soils; (4) development of better analytical procedures of interpreting in-situ test data; (5) the role of micro and macrofabric in affecting the shear strength, consolidation and permeability; (6) improvement in laboratory techniques to test tropical residual soils including the saturation of undisturbed samples; (7) selection of sample size, preparation of sample for various field and laboratory tests in relation to the type of material to be tested; (8) development of improved index tests and the use of void ratio and specific gravity properties for preliminary estimation of strength and compressibility characteristics. Obviously, this should relate to a particular group or location or origin; (9) the role of bonds in affecting the engineering behaviour of fine grained highly weathered material; (10) collapse behaviour of partly saturated residual tropical soil on wetting - mechanisims involved, test procedures and predictions; and (11) the effect of wetting and drying on the engineering properties of soils.

The Upper Ordovician Winterhouse Formation of Western Newfoundland contains a, hitherto undescribed, well-preserved and diverse assemblage of trace fossils. This study provides the first systematic ichnological review of the area. 20 ichnotaxa are documented herein from the mudstone and sandstone storm deposits of the formation. A detailed morphologic three-dimensional reconstruction and analysis of a complex Parahaentzschelinia-like burrow system that is prolific throughout the formation is also undertaken. This analysis allows for a reconsideration of the trace-maker's ethology and paleobiology, and highlights a need for a systematic ichnotaxonomic review of Parahaentzschelinia. Additional reconstructions of natural mineral-filled fractures associated with Parahaentzschelinia-like burrows in the cemented silt-rich fine-grained sandstones illustrate that the burrows create planes of weakness within the cemented sandstone, along which natural fractures preferentially propagate. This suggests that these trace fossils create mechanical heterogeneities that can steer fracture development, and can potentially have a dramatic effect on reservoir charactertstics in bioturbated reservoirs where induced fracturing techniques may be employed.

Purpose
To examine the effect of a home visit-based visual rehabilitation intervention on: (1) self-reported visual function and (2) depression, wellbeing, loneliness, adjustment to visual loss, and generic health-related quality of life.

Methods
In an exploratory, assessor-masked, individually randomized, single-center controlled trial, 67 participants (age: 75.22 ± 16.21 years) with low vision were allocated either to receive the home visit-based visual rehabilitation intervention (n = 35) or to a waiting list control arm (n = 32). Outcome measures were collected by telephone interview at baseline and 6 months later. The primary outcome measure was the 48-item Veterans Affairs Low Vision Visual Functioning Questionnaire (VA LV VFQ-48). Secondary outcome measures were: the Patient Health Questionnaire; the Warwick-Edinburgh Mental Well-being Scale, the Adjustment to Age-related Visual Loss Scale, the standardized health-related quality of life questionnaire, and the University of California, Los Angeles Loneliness Scale. Questionnaire scores at follow-up were analyzed using analysis of covariance, controlling for the baseline score and the variables, age, number of comorbidities, visual acuity, and baseline wellbeing score.

Results
Visual function (VA LV VFQ-48) improved at follow-up in both groups, with a significantly greater improvement demonstrated by the intervention group (95% confidence interval, 0.33-0.68 logits, P = 0.031), with a moderate effect size (0.55). Secondary outcomes did not indicate any statistically significant differences between groups.

Conclusions
The study provides preliminary evidence that a home visit-based visual rehabilitation intervention has a positive influence on vision-related functional outcomes. A larger trial with an expanded intervention to include a mental health component and cost-effectiveness analysis is needed. (ISRCTN.com number, 44807874.).

"[...] Shortly before I left his land, probably for ever, he [the informant] came to see me and we had an outwardly cheerful drink together; presently, he grew quiet, then said: 'When your motor car sets out in the early morning do not expect to see me nearby. When somebody dies we Ndembu do not rejoice, we have a mourning ceremony" (i). Turner's moving description of his last meeting with one of his informants illuminates a situation fairly typical of the relationship between anthropologists and the members of the societies which they study *. Turner's interpretation of his informant's remark concentrates on other aspects, yet what dominates the situation is the fact that the white British anthropologist and his close informant from an African tribal society are likely to part for ever. It appears from this case that the deeper the understanding and sympathy established between the anthropologist and his hosts, the sharper becomes the perception about the inevitable eventual total separation. Neither the anthropologist nor his hosts are deceived during fieldwork by the anthropologist's apparent absorption in his host society, even when he fraternizes with a particular kinship group (2). He remains extremely different from his host society and little is known and comprehended about his social roots (3). He is as if a visitor from another planet to which he will return in due time (4). Such a situation enables the social anthropologist to sustain a remarkable degree of detachment and objectivity toward the subjects of his

In this study, we will discuss the engineering construction of a special sixth generation (6G) antenna, based on the fractal called Minkowski's loop. The antenna has the shape of this known fractal, set at four iterations, to obtain maximum performance. The frequency bands for which this 6G fractal antenna was designed in the current paper are 170 GHz to 260 GHz (WR-4) and 110 GHz to 170 GHz (WR-6), respectively. The three resonant frequencies, optimally used, are equal to 140 GHz (WR-6) for the first, 182 GHz (WR-4) for the second and 191 GHz (WR-4) for the third. For these frequencies the electromagnetic behaviors of fractal antennas and their graphical representations are highlighted.

The results show that the three energy supplies would be complementary for integrated power.


HIV-1 genetic variability and the potential association with modes of transmission exposure categories gender and distribution over time were investigated in 1993-96 in 131 HIV-infected individuals from Rio de Janeiro Brazil. The study group included 28 homosexual and 15 bisexual men 55 heterosexuals 24 injecting drug users and 1 blood transfusion recipient. HIV-1 env subtyping by heteroduplex mobility assay identified 106 infections (80.9%) with subtype B 20 (15.3%) with subtype F and 1 (0.8%)--the first reported in Brazil--with subtype D. According to restriction fragment length polymorphism with fok 1 restriction enzyme 39 (37%) of the 106 subtype B samples had the GWGR motif at the tip of the V3 loop typically found in subtype B in Brazil. A previous study conducted in Sao Paulo Brazil suggested that subtype F could be related specifically to injecting drug use. The present study however found no significant associations between HIV-1 subtypes and exposure categories gender or mode of transmission. The long-lasting nature of the AIDS epidemic in Brazil may have favored the dispersion of the HIV-1 subtypes among the various exposure categories.

The purpose of this study was to pretest the feasibility of standardizing the Cooperative Preschool Inventory (CPI) by Bettye Caldwell for use as a school readiness test in Korea.
 The Korean version of the CPI, renamed the School Readiness Test, was developed with 66 items for this study. The subjects of the study were 420 children, ages 3 to 6, attending nursery schools, day care centers, and kindergartens in Seoul area. The test was administered individually during the period of July 3 to August 10, 1978 by seven examiners who had received training in the administration of the test.
 The major findings were as follows:
 1. The increment of the average raw scores was sufficiently discriminable as age increased.
 2. There was no significant differences at the 5 percent level in average scores between
boys and girls.
 3. The average scores of Korean children were a little higher than the sample for standardization of the CPI in the United States.
 4. The split-half reliability coefficient was .94 with the correction by Spearman-Brown formula, and KR-20 reliability coefficient was .93.
 5. The correlation coefficient between the School Readiness Test and the Intelligence Test for Children was found .53 for 46 subjects.
 6. The average difficulty index for the items was 71, indicating that 'many items were relatively easy to answer; and there were 30 items showing low discriminating power with the discrimination index of .25 or below.
 7. The percentile ranks were prepared for each age group to provide a temporary norm.

semipassive bimorph flexible mirrors is one of the most widely used devices for correction of the given laser beam intensity. However, the key disadvantage of these kind of mirrors is their low spatial resolution of the corrected phase. In this work, we present two approaches for increasing spatial resolution of the deformable mirrors – one to use a multilayer bimorph mirrors and another to put higher density of control electrodes and use ultrasonic welding to make the wire connection to these electrodes.

An open architecture multimedia document publication system is described which integrates a number of different representation technologies to provide a medium offering a wide spectrum of usage, from emulation of current paper publication, through electronic document delivery, multimedia inclusion of video and sound, structured hypermedia linkage, and formal knowledge representation supporting simulation and inference. The research is targeted on exploring new forms of scholarly communication, and the publication system supports collaborative document development, the authentication of disseminated material, and the citation, annotation and reuse of such material. The document publication system provides a rich word processing and page makeup environment with all the facilities normally expected, and adds multimedia, hypermedia and computational facilities incrementally and naturally, with careful attention to the usability of the human-computer interface. The result is an interactive document in which knowledge is represented in a variety of ways, some targeted on human interaction, some targeted on computational analysis, simulation and inference, and such that the document can be printed as a conventional paper or book losing the dynamic aspects of the material but retaining the visual representation.
