Abstract Paravietnura gen. n. is described and established for two new species of Neanurini from the Caucasus. The new genus is characterized by an unusual combination of features: the fusion of all lateral tubercles on the head into a single mass, the strong reduction of chaetae on the head, the fusion of cephalic tubercles Af and Oc into a transverse band, the absence of labial chaetae f, the presence of microchaetae on furca rudimentary, and the penultimate abdominal tergum with two tubercles separated along the midline. Paravietnura gen. n. strongly resembles Vietnura Deharveng & Bedos, 2000, a monotypic genus up to date known only from Vietnam. The main characteristics of Paravietnura notabilis sp. n. include an ogival labrum, the absence of chaetae A on the head, relatively thick and widely sheathed long macrochaetae, and minute microchaetae without chaetopores on furca rudimentary. Paravietnura insolita sp. n. differs from the previous species in chaetotaxic details, the size of furcal microchaetae, and the shape of the labrum. Short comments on the generic diversity of the tribe in the Western Palaearctic are also provided.

Due to limited resources (e.g. human, financial, knowledge, etc.), Smalland Medium sized Enterprises run the risk to miss the Digital Transformation of its systems. Especially the manufacturing industry – a strategic industry within the European Union that employs millions of workers and provide tremendous Gross Domestic Product to the partner countries – faces technology changes and increased challenges for implementation. As reaction to the challenges of the manufacturing industry, the European Union launched the Factory of the Future programme and the European Digital Innovation Hub programme. Within this article at hand, the literately and empirically endeavours towards the design and development of the Digital Innovation Hub: Business Intelligence & Innovation within the region of Vorarlberg are presented. In doing so, a narrative literature review about the academic discipline of Service Science – the guiding theory to innovate service systems – and an empirical research about the motivation, status quo, vision and strategy towards the Digital Transformation and Industry 4.0 paradigm of the manufacturing industry within the region of the Federal State of Vorarlberg are presented.


The article highlights the analysis of approaches to formulating the concept of "development". Also, the main features were determined, and their regulatory and legal basis was investigated. The article outlines the problems of development projects in the form of public-private partnerships and ways to solve them.
Development as a form of public-private partnership has a long history, but the study of this phenomenon has become most relevant in recent decades.
The study of the development, its legal basis, problems, methods of solving them, and their main characteristics is now a priority task since the political, economic, legal, and social positions of bodies are being formed to achieve cooperation, to implement programs of social and economic development, investment and infrastructure projects.
Implemented state-legal partnership projects yield positive results. It is this experience that the state authorities can use to solve many problems of the economic complex in order to increase the level and efficiency of service provision.


This paper presents a novel circuit technique to improve the testability of NORA (NO RAce) CMOS circuits. It is based on the structure, properties and operations of NORA CMOS. The precharge and evaluation properties of NORA CMOS enable one to design simple testing circuit for output stuck-at-zero, stuck-at-one, stuck-open and stuck-on faults. Area and time considerations, as well as the applications of this testability enhancement technique are also discussed.


Khambati and colleagues report the first Canadian ser ies of laparo-endoscopic single site surgery (LESS) in the pediatric population.1 Laparoscopy on the pediat ric population is often challenging due to limited space and almost non-exiting ergonomic positioning. Nonetheless, one experienced laparoscopist is still pushing the limits. Khambati and colleagues report their experience with several frequent pediatric procedures, such as the simple Palomo varico celectomy to the more challenging pyeloplasty.1 Although the indications for surgery are heterogeneous, as are patients' size and age (range: 7.5-17.5 years), the authors demon strate that LESS is widely applicable to different procedures performed by pediatric urologists. LESS may be extremely challenging even for the most experienced laparoscopist as the triangulation of the instruments and the usual positioning of the camera w ill both differ. Dry training in the laboratory is probably the best way to acquire the adequate hand-eye coordination to achieve surgical times comparable to those obtained for standard laparoscopic procedures. LESS series are rapidly increasing in numbers in the litera ture. The reported procedures are becoming more complex with time, using different types of instruments and devices.2'4 It would be interesting to evaluate whether one specific access port is more suitable for pediatric cases. In the actual report, the authors used three different devices. Their report suggests that they preferred one specific access port as they used it in their latter cases. They typically used one straight and one articulated instrument of different lengths, in an attempt to prevent extracorporal clashing. This is combined with an articulated 5-mm camera that provided a 100° angu lation. This corroborates Sanchez-Margallo and colleagues' conclusion that using two articulated instruments impairs surgical easiness.5 Postoperative cosmetic appearance and limited puncture of the peritoneum are indisputable advantages of LESS. The barely visible um bilical scar w ill make it more d ifficu lt for physicians to recapitulate the patient surgical history from the physical examination, as it was previously pos sible. W hile the authors suggested that the requirement for narcotics and the length of the hospital stay w ill be lower with LESS, I doubt that this w ill be significant if analyzed in a prospective study as they both are already very low in the pediatric population. We know that our patients gen erally are more inconvenienced by the referred shoulder pain created by the peritoneal insufflation than by the pain secondary to each and single incisions. Khambati and col leagues clearly mentioned that their results are likely not reproducible by the standard pediatric urologist.1 This state ment follows the European Association of Urology grade A recommendations on Roboticand Single-site Surgery in Urology.3 Nevertheless, surgical time should be carefully monitored by beginners as neurotoxicity related to anes thesia is now widely reported.6 Complications should also be well-identified as some series suggest that they may be more prevalent when LESS is performed compared to stan dard laparoscopy.2,3 Finally, the present cohort demonstrates the safety and feasibility of transumbilical LESS in the pediatric urological population. Randomized studies are required to better define the usefulness of LESS as no demonstrated or documented benefits over standard laparoscopic approaches have been reported for the pediatric population.


As one speaker at the conference put it, "age has advanced but not the attitude towards age". The problem of aging concerns particularly people who have come to the end of their earning life and who have to subsist on pensions or other limited material resources. Unlike citizens with a fine record of achievement who can retire in comfort, retaining "honour, love, obedience, troops of friends", the drawer of water and hewer of wood who outlives his economic utility is apt to find himself forgotten if not rejected. The position is aggravated when the aging person has become an isolate through misfortune or by reason of temperament. Neglect of bodily, mental and spiritual needs ensues. As Andre Maurois· pointed out, "the true evil is not the weakening of the body but the indifference of the soul". Anything that can be done to teach people at any age to live for worthy purposes will render them more fit to meet not the least critical period of their lives, though it is not to be expected that -the average teenager will appreciate that how he conducts himself has an important bearing on the sort of person he will be in forty years' time. Much is being done to lighten the burdens of advancing years, but more attention might be directed to preventive measures. In addition to the ascertainment, correction and treatment of disabilities which conduce to reduced activity and isolation, much can be achieved through social and recreational centres to keep the aged in touch with the community. The time for remedy is past when the old have become "cold and withered and of intolerable entrails". The development of a community conscience and neighbourly interest in these matters is a necessary complement to visiting and other services. The conference rightly stressed the value of local community as against centrally controlled services and efforts. In this connexion it may be pointed out that there is a tendency to exaggerate the need for special facilities for the aging. To treat them as a special group fosters their feeling of isolation from the community. Social and recreational centres should as far as possible retain a family atmosphere in which all ages have the opportunity of meeting together. There is always room for better use of existing facilities, and in this respect information centres perform an important function. In his summary of the work of the conference Dr. Alan Stoller put much of what was most important in a nutshell, when he emphasized the need to avoid patronage, to discourage dependence and to preserve selfrespect in the aged. "Above all, they must have something to do, interests to maintain, companionship to enjoy and ideals to live for."


Objective: Coronary anomalies do not generate symptoms, it is incidental findings when performing a coronary angiography in a patient with ischemic heart disease or valvular heart disease. The anomalous origin of the circumflex (LCX) of the right coronary artery (RCA) is one of the common anomalies. We describe a case of CX orifice  arising from right coronary sinus in a ``shotgun`` manner with orifice of RCA and successful percutaneous coronary intervention (PCI).

Case Report: In this case, the anomalous incidental finding was the arising of the CX artery in "shotgun" shape with the RCA (separate ostium) in a clinic scenario of anterior ST-segment elevation myocardial infarction wherein the patient received fibrinolytic therapy with alteplase, presenting reperfusion criteria (&qt;50% ST-segment resolution at 60 minutes and relief angina) and then underwent to successful PCI.

Conclusion: The ectopic origin of the CX is a well-recognized variant, which is considered the most common coronary anomaly. Although this anomaly is classified as benign and asymptomatic, a few cases of sudden death, myocardial infarction, and angina pectoris in the absence of atherosclerotic lesion have been reported. We shared successful PCI in such coronary anomaly in a patients with ST elevation anterior myocardial infarction.  Such coronary anomalies should be considered as well in patients with STEMI undergoing PCI.


In this paper, a truly meshless method, the Meshless Local Petrov-Galerkin (MLPG) Method, is developed for three-dimensional elasto-statics. The two simplest members of MLPG family of methods, the MLPG type 5 and MLPG type 2, are combined, in order to reduce the computational requirements and to obtain high efficiency. The MLPG5 method is applied at the nodes inside the 3-D domain, so that any domain integration is eliminated altogether, if no body forces are involved. The MLPG 2 method is applied at the nodes that are on the boundaries, and on the interfaces of material discontinuities, so that the boundary conditions, and material discontinuities, are satisfied without any further tedious integration. Two classical three-dimensional elasto-statics problems, viz., the Boussinesq problem, and the Eshelby's inclusion problem, are analyzed with the current method. The MLPG results agree excellently with the analytical solutions, and demonstrate their superiority over the results obtained from the traditional displacement-finite-element method. The MLPG method is straightforward, easy to implement, efficient, and accurate; therefore it holds a great promise to replace the finite element method in three-dimensional analysis in the near future. keyword: meshless method, Meshless Local PetrovGalerkin (MLPG) methods, local symmetric weak form, Moving Least Squares (MLS) interpolation

In 2015, Veritas Technologies LLC coined the term databerg. Most companies have 86% of wasteful data, while only 14% of their total data is mission critical. No such information is available for the world wide web. Based on an analogy between organizational data and the internet, we expect the proportions to be much higher for the internet. Consequently, most of the internet can be classified as information waste, and should be detected as such by waste detectors. Waste detectors that use objective metrics achieve good performance. Subjective metrics, however, are still a big problem: what is waste for one, might not be waste for another person. This is due to the various interests one person might have. We call this bias of interests. Previous studies have built subjective models that indicate whether a website provides value, i.e., whether it is wasteful or not. Unfortunately, their accuracies are low; most likely, due to those interests. In this study, we outlay previous research in the field. Then, a measurement instrument is created that gathers test data. The instrument includes a correction mechanism to take into account the assumed bias of interests. Test results show intuitive improvement, but the assumed bias factor is not significant. Finally, a tool is developed that attempts to measure website waste subjectively. This tool will be usable for both waste detection and future research.


ObjectiveTo study the effects of simvastatin on the hypertrophy of cultured rat cardiac myocytes induced by serum and investigate the role of phosphoinositide 3-kinase(PI3K)/protein kinase B(PKB).MethodsImage analysis system was used to measure cell surface area.Protein synthesis of myocytes derived from cultured neonatal Sprague-Dawley(SD) was measured via -leucine incorporation.The expression level of mRNA of atrial natriuretic peptide(ANP)in myocytes was determined with reverse transcription polymerase chain reaction(RT-PCR).RT-PCR and Western blot were used to study the mRNA and protein expression level of PKB.Rlllesults(1)Cardiac myocytes surface area was lowered in serum-free group than in 15% serum group (538.04±118.60)μm~ 2 vs (1611.16±160.75)μm~ 2(P0.01).Simvastatin decreased cell surface area in a concentration dependent manner.Cell surface area in 10~ -5 and 10~ -6 mol/L simvastatin groups were (799.84±167.70)μm~ 2 and (1076.88±199.28)μm~ 2, which were both significantly lower than that in serum group(both P0.01).(2) Incorporation rate of serum-free group was (1305±92)cpm/well .It was much higher in serum group(2369±106)cpm/well than that in serum-free group(P0.01).Incorporation rate of -leucine in 10~ -5 and 10~ -6 mol/L simvastatin groups were (1 707±101)cpm/well and (1 962±125)cpm/well, respectively, which were both lower than that in serum group(P0.01).(3)With the increase of simvastatin concentrations, the ANP mRNA expression was decreased gradually compared with that of serum group(0.60±0.03).The level of ANP mRNA in 10~ -5 and 10~ -6 mol/L simvastatin groups were 0.29±0.03 and 0.40±0.03, which were both lower than that in serum group(P0.01).(4)Simvastatin inhibited the expression of PKB mRNA induced by serum in a concentration dependent manner.The PKB mRNA expression level in serum group was 0.51±0.03.The PKB mRNA level in 10~ -5 and 10~ -6 mol/L simvastatin groups were 0.28±0.02 and 0.36±0.03, respectively, which were both much lower than that of serum group(P0.01).Similarly, compared with serum group(60.80±3.49), the protein level of PKB in 10~ -5 and 10~ -6 mol/L simvastatin groups (42.41±2.83 and 45.68±3.43) were also both significantly decreased(P0.01).ConclusionSimvastatin inhibit the hypertrophy of cultured rat cardiac myocytes induced by serum.The mechanism might be related with the decrease of expression level of PKB.


Background:We first introduced this meta-analysis was to assess the accuracy of arterial spin labeling (ASL) in the differentiating high-grade gliomas (HGG) from brain solitary metastases (BSM). Methods:The PubMed,Web of Knowledge, and Cochrane Libraries and China National Knowledge Infrastructure databases were searched up to August 31, 2018. The pooled weighted sensitivity and specificity, summary receiver operating characteristic curve (SROC), sensitivity analysis, and threshold effect analysis were performed on Stata version 12.0 and Meta-Disc version 1.4. Deeks' funnel plot asymmetry test was performed to assess publication bias. Results:Of 5 eligible articles, of the 346 lesions from 346 patients, 274 were HGG, and 72 were BSM. The forest pooled sensitivity of 0.88 (95% confidence interval [CI]: 0.65, 0.96) and specificity of 0.85 (95% CI: 0.74, 0.92) of ASL were reported in this metaanalysis. The pooled area under the curve of SROC was 0.92 (95% CI: 0.89, 0.94). Sensitivity analysis demonstrated that the pooled estimates were reliable. No evident publication bias was obtained (P= .38). Conclusion: The parameters derived from ASL with high accuracy in differentiating HGG from BSM. However, results must be interpreted with caution due to the small sample size considered. Large sample prospective studies were necessary to assess and confirm its clinical value. Abbreviations: ASL = arterial spin labeling, AUC = area under the curve, BSM = brain solitary metastases, CNKI = China Knowledge Resource Integrated database, CI = confidence interval, DOR = diagnostic odds ratio, FN = false-negative, FP = falsepositive, HGG = high-grade gliomas, rCBF = related cerebral blood flow, SEN = sensitivity, SPE = specificity, SROC = summary receiver operating characteristic curve, TP = True-positive, TN = true-negative.


Objective:To investigate the expression of angiopoietin-2(Ang-2),vascular endothelial growth factor(VEGF) and their relationships with clinicopathologic characteristics and tumor angiogenesis in gastric carcinoma(GC).Methods:The expressions of Ang-2,VEGF and microvessel density(MVD)in 55 cases of gastric cancer(GC),12 cases of adjacent normal tissue and 12 cases normal gastric tissues were evaluated by immunohistochemistry.Results:The expressions of Ang-2,VEGF and MVD were significantly higher in GC than in adjacent normal tissues and normal gastric tissues(P0.05).Ang-2 and VEGF expressions were correlated with infiltration depth,lymph node metastasis,TNM stages and tumor's differentiation degrees(P0.05).A significant correlation was found between Ang-2 and VEGF expressions(P0.05).Conclusion:There are high expressions of Ang-2 and VEGF in GC,which indicate that Ang-2 and VEGF play important roles in promoting tumor angiogenesis and progression of GC.


A high molecular‐weight protein from Escherichia coli sharing structural ho mo logy at the protein level with a yeast heavy‐chain myosin encoded by the MYO1 gene is described. This 180kD protein (180‐HMP) can be enriched in cell fractions following the procedure normally utilized for the purification of non‐muscle myosins. In Western blots this protein cross‐reacts with a monoclonal antibody against yeast heavy‐chain myosin. Moreover, antibodies raised against the 180kD protein cross‐react with the yeast myosin and with a myosin heavy chain from chicken. Recognition by anti‐180‐HMP antibodies of an overexpressed fragment of yeast myosin encoded by MYO1 allows the localization of one of the shared epitopes to a specific region around the ATP binding site of the yeast myosin heavy chain. The existence of a high molecular‐weight protein with structural similarity to myosin in E. coli raises the possibility that such a protein might generate the force required for movement in processes such as nucleoid segregation and cell division.


Author(s): Luong, Mui Nhuc | Advisor(s): Cho, Ken WY | Abstract: Understanding the molecular mechanisms that govern animal development is one of the major challenges in developmental biology. The TGF-β members such as the bone morophogenetic proteins (BMP) play critical and diverse roles throughout embryonic development in both vertebrates and invertebrates and understanding the mechanisms by which they initiate specific cellular differentiation programs and control of gene expression is important. This dissertation will focus on the characterization of the BMP responsive element (BRE) identified in our lab. Additionally, I will demonstrate that the BRE functions as an activator in BRE-mediated BMP signaling and is responsible for modulating a subset of BMP target genes in mouse embryonic stem (ES) cells. To complement our in vitro studies, our lab also investigated the role of BMPs in early mouse embryonic development. Our studies reveal that BMP signaling may be active in the inner cell mass (ICM) during mouse embryogenesis and is playing a role in sustaining pluriopotency by interacting with the Oct4/Sox2/Nanog network.

Of the enormous amount of publication on Thomas Hardy, it is astonishing how relatively little has been produced on his poetry. To be sure. The Dynasts has had the benefit of some exceptionally diligent and perspicacious scholarship not only in the recent studies by Harold Orel and Walter F. Wright, but also in J. 0. Bailey's own work which appeared in 1956. Otherwise, however, significant book-length studies of Hardy's poetry are scant: Hickson's in 1931, Southworth's in 1947, Hynes· in I96I, and most recently, Kenneth Marsden's The Poems of Thomas Hardy in I969. One reason for this neglect is probably that Hardy's poetry is curiously resistant to the modes of critical discourse which have tended to predominate in the last forty years. Another, however, is that there is often an absence of the kinds of information about the background of Hardy's poems needed to make confident critical discussion possible. For Hardy's poetry, in spite of the apparent simplicity of so much of it, has been more desperately in need of a gloss than has been generally recognized. It is safe to say that the remark in The Later Years to the effect that "there is more autobiography in a hundred lines of Mr. Hardy's poetry than in all the novels" has been taken by most readers as one of those casual assertions which are not to be credited seriously. Professor Bailey's The Poetry of Thomas Hardy now amply demonstrates that the assertion is to be carefully heeded indeed. The importance of the kinds of information Professor Bailey provides is clearly evident if one compares the attempt of an excellent critic like J. Hillis Miller to provide a full reading of "Wessex Heights" (Critical Quarterly. X [Winter I968], 339-59) with Bailey's entry for the poem. Such comparisons will make clear, I think, that anyone who wishes to propose a careful reading of one of Hardy's poems cannot afford to overlook Bailey's book.

Henson, J. M., and Caesar-TonThat, T. C. 1995. Mitochondrial plasmids of the Gaeumannomyces-Phialophora complex and their detection by primed, in situ fluorescence labeling. Experimental Mycology 19, 263-274. Double-stranded, linear DNA mitochondrial plasmids were detected in most Gaeumannomyces graminis var. tritici and var. avenae isolates, but were infrequently detected in G. graminis var. graminis , and only detected once in other Gaeumannomyces or Magnaporthe species. Plasmids were 4-11 kb and were apparently blocked at their 5′ termini, as they were resistant to 5′ → 3′ exonuclease digestion. Two plasmids that shared homology were further characterized. Apparently they were not derived from the mitochondrial or nuclear genomes as they did not hybridize strongly to them. An internal fragment was cloned from one plasmid and used as a primer for primed, in situ labeling with cryosectioned hyphae. Plasmid-bearing strains had fluorescent signal in a pattern expected of a mitochondrial location for plasmids, whereas plasmid-less strains did not fluoresce. This is the first use of cryosectioned hyphae and mitochondrial probes with in situ fluorescence labeling in fungi.


Recently, Flexible Printed Circuit (FPC) is extensively used in portable electronic products because of its excellent flexibility and twistability. Compared with rigid boards, FPC usually experiences much larger deformation in its usages. However, most available packaging-components at the moment are rigid, FPC-contained products may cause failures under accidental mechanical conditions, such as drop, bending and twisting. Many literatures have been published on the reliability of rigid boards, while much less results were reported for the research of drop performance of FPCs [1,2,3]. In this paper, the mechanical reliability of a BGA mounted on FPC under drop impact has been studied by simulations. To make the model more close to the practical products, one plastic cuboid with the size of 89mm×69.5mm×8mm taken as the housing is involved in the simulation model. The FPC mounted with a BGA is fixed in the cuboid through four screw bars and dropped from 1.5 meters height to the concrete ground. Drop direction, BGA layout location and solder joint shape and size, as the three main factors are used in the reliability study. In practical drop reliability tests, six orthogonal drop tests are taken. As well as considered that the simulation sample is rectangle, the simulations of different drop directions are divided into two groups according to if the long housing edge or short housing edge impact with ground firstly. To simulate the different drop impact angle based on the orthogonal drop, several drop cases were built by setting the angle from 0º to 90º between the ground and model. In all of above drop cases, the single difference is the drop direction. To study the impaction of BGA location, simulation cases with the BGA moved from edge to center had been simulated also. The height and the diameter of solder joint is another important factor to the connection reliability. To predict its impaction, solder joint height varied from 0.15mm to 0.23mm and diameter varied from 0.25mm to 0.35mm were considered in the models. Through the corresponding simulations, analysis and comparison, it is found that the strain rate could be up to a peak of 105/s, but most of the time, the strain rate locates in the range of 102/s. The max stress decreases with the increasing of the solder joint height. Drop reliability can be improved by increasing the height of solder joints. The max stress increases when the diameter of the solder joint increased from 0.25mm to 0.3mm, while decreases when the diameter increased from 0.3mm to 0.35mm. Drop reliability can be only improved when the diameter is larger than 0.3mm.


1 Student (M.E.) Electrical Engineering Department, MSS'S COE, Jalna, Maharashtra, India 2 Assistant Professor, Electrical Engineering Department, MSS'S COE, Jalna, Maharashtra, India ---------------------------------------------------------------------***--------------------------------------------------------------------Abstract: It was always recognized that ac power transmission over long lines was primarily limited by the series reactive impedance of the line. Thyristor controlled series compensator (TCSC) device is a series compensator to govern the power flow by compensating the reactance of the transmission line. This paper presents a conceptual study to adopt an optimum value for the capacitor and inductor of a TCSC device. Degree of Series compensation (K) brings an idea of selecting the TCSC capacitor. The Reactance characteristic curve is analyzed with resonant point for different values of 'ω' which defines the square root of ratio between capacitive and inductive reactance. The study is helpful in selecting an appropriate value for TCSC inductor which has influence on multi resonance point in TCSC device.


This paper examines how pedagogical approaches in writing classrooms can better draw upon the whole of students' abilities--intellectual, affective, and creative. Many teachers know too well that students rarely respond well to writing prompts which monopolize their cognitive, linear capacities while ignoring creative strategies and affective approaches to writing and thinking. Allowing creativity to merge with pedagogical theories taps into the multifaceted resources inherent in each student. Creativity in writing instruction refers to thought processes, rhetorical approaches, and functional techniques used in writing. Functional techniques in fictional writing are matters of point of view, voice, tone, rhythm, grammar, and setting. Fictional techniques are also matters of scene, summary, and description. As instructors bring exercises into the classroom that utilize students' creative abilities, the likelihood is that their writing will become autotelic, or intrinsically motivated. They will no longer venture into a rhetorical purpose solely because the instructor tells them to do so, or because they want a good grade--they will instead dive into a writing task because it is exciting, challenging, or even fun. The more writers are able to utilize their creative capacities in producing texts, the more they will simply enjoy the task in and of itself. The more teachers encourage creative and affective approaches to writing, the more they will increase the autotelic factor in students' writing processes. (Contains eight references.)

As teachers, we so often foreground our students' intellectual abilities while at the same time either consciously ignoring (or unconsciously turning away from) their creative abilities. Many of us know all too well that students rarely respond well to writing prompts which monopolize their cognitive, linear capacities while ignoring creative strategies and affective approaches to writing and thinking. By allowing theories of creativity to merge with our pedagogical theories, we can better tap into the multifaceted resources inherent in each one of our students. First I will attempt to define creativity in terms of thought process, rhetorical strategy and writing technique. Then, after examining the role of habit in thinking and writing, I will briefly review Raffel's notion of awareness. Notions of Csikszentmihalyi's flow and autotelism will then be examined. Finally, I will conclude by making explicit connections between creative theory and writing


Few accounts of funeral ceremonies performed for the rulers of France before the early fifteenth century are now extant.* The rare eyewitness reports of such rites are generally terse and abbreviated, and there survive only fragments of the fiscal accounts listing expenses for the services, which inevitably provide a wealth of detail overlooked or ignored by observers. The want of information cannot be attributed solely to the disappearance of once abundant documentary remains, for even in the early fifteenth century such sources were not easily accessible. The author of an elaborate description of the funeral of Charles VI in 1422 confessed that he had written the account as an aide-memoire for future royal funerals, to prevent the disagreement and confusion which, in the absence of written records and living witnesses of earlier ceremonies, had arisen in connection with Charles's service.' For the history of royal funeral ritual in early fourteenth-century


In 1975 the five countries of ASEAN proposed to the communist countries of Indochina to join in the creation of a " zone of peace, liberty and neutrality " in South-East Asia. They then refused to accept the Cambodian regime resulting from Vietnam's armed intervention in Cambodia in 1979. ASEAN members are now working to maintain a Khmer Rouge representation in the UN and to isolate Vietnam internationally, but they are much more divided on substance when it cornes to a dialogue with Vietnam : Thailand and Singapore support China's policy against Vietnam, the ally of the USSR, but Malaysia and Indonesia continue to see Peking as the "principal danger" and consider it possible to cooperate with Vietnam, which has shown ils ability to resist China, for the purpose of set limes up a new regional order. These differences do not, however, appear likely to lead to a break. The key to the problem will be the evolution of Bangkok's and Hanoi's positions.


Over the last years, several stationarity tests have been proposed. One of these methods uses time-frequency representations and stationarized replicas of the signal (known as surrogates) for testing wide-sense stationarity. In this letter, we propose a procedure to improve the original surrogate test. The proposed methodology can be seen as a guideline on how the surrogate test can be improved. We show mathematically that the modified test should exhibit improved classification performance. Numerical simulations on synthetic and real-world signals are carried out to evaluate the modified test against competing ones.


Objective To know the status of knowledge, attitude and behavior of tuberculosis among the middle school students in Binhai newly developed area Hangu of Tianjin and to evaluate the effects of tuberculosis health education intervention. Methods A total of more than 800 students in 3 middle schools were performed the preinterventional questionnaires. Then the same questionnaires were conducted after implementing the health education intervention by various measures which students would like to get the knowledge of tuberculosis prevention and treatment, including health lecture, knowledge competition, class meeting, blackboard newspaper, billboard, propaganda panel, brochure. The results of the questionnaires before and after health education intervention were compared and analyzed. Result After tuberculosis health education intervention, the single awareness ratio of 5 key messages concerning infectivity, transmission routes, suspicious symptoms, preventive measures and free policy was significantly increased, from 60.20 %, 59.40 %,65.20 %, 16.10 %, 46.00 % to 95.40 %, 81.00 %, 84.50 %, 39.20 %, 73.40 % respectively(P0.01). The total awareness ratio of the key messages within survey respondents was increased from 49.40 % to 74.70 %(P0.01). The ratio of holding reasonable attitude concerning'the possibility of suffering from tuberculosis is in all likelihood','tuberculosis can be prevented and treated','tuberculosis patients should not be discriminated'and'would like to get health knowledge'was increased respectively from 44.1 %, 44.90 %, 42.00 %, 79.90 % before intervention to 63.70 %, 81.30 %,69.50 %, 96.30 % after intervention(P0.01).

Summary. Nine species of Poa are recognized in Ethiopia. Their variation and interrelationships are discussed and a key and descriptions are provided. The new Ethiopian endemic species P. hedbergii S. M. Phillips is described. Poa is one of the largest genera in the Gramineae, with about five hundred species in temperate and cold regions of the World. It extends to mountains in the tropics, including the uplands of Ethiopia at altitudes mainly above 2000 m. Poa is a genus of notorious taxonomic difficulty, the uniformity of structure of its spikelets being coupled with the great variability of those few characters on which the taxonomist could have hoped to rely, leading to difficulties almost unparalleled in the family in the delimitation of species. This variability arises largely through extensive introgression, polyploidy and sometimes subsequent apomixis (Nygren 1954). The necessity of writing an account of Poa for the 'Flora of Ethiopia' brought about the present study, and it immediately became apparent that the Ethiopian species are no exception to the problems which pervade the genus elsewhere in the world. These difficulties in Ethiopia are compounded by the fact that most species are still very poorly represented in herbaria, owing to the remoteness and inaccessibility of the high mountains where they grow. Indeed, of the nine species listed here, only P. leptoclada and P. schimperiana are at all well collected, these being the only two which occur widely at altitudes below 3500 m. In a genus where the assessment of infraspecific variability is so important for an understanding of which characters might be used for delimiting species, it is obvious that caution is required when only a few specimens are to hand. Recent studies of the genus, e.g. Tateoka on Japanese Poa (1985), Edgar on New Zealand Poa (1986) and Vickery on the Australian species (1970) have relied on extensive field work and the examination of large numbers of herbarium specimens. There is no doubt that such a broad approach, including cytogenetic studies, is the only way in which we can hope to understand the inherent variability of this genus. Unfortunately, such a combined approach is impracticable for the Ethiopian species as not only do they grow in remote areas, as already mentioned, but are of very little economic importance for the country, so would hardly justify at present the large expenditure of time and effort involved. However, taxonomic groundwork based on herbarium specimens still remains the basis for further studies, so the aim of this paper is to present as complete a taxonomic treatment as the few available specimens will allow. It should be regarded as a first approximation only, and it is confidently expected that the number of species present will rise as more material is collected. The wide range of infraspecific variability accepted here in characters such as ligule length and lemma hairiness and size, when compared with the many fine characters used to


We present a multiagent coordination technique to maintain throughput of a large-scale agent network system in the face of failures of agents. Failures do not just deteriorate throughput of the system but also create and change bottlenecks in the system. Since loss of bottleneck's capacity degrades the overall system performance, the system should identify bottlenecks dynamically and keep their utilization at a high level. In our system, CABS, information about an agent's urgency of jobs to fulfill demanded throughput and maintain its utilization is passed to upstream agents in the network. Upstream agents utilize this information to identify bottleneck agents and coordinate their actions to provide the bottlenecks with necessary and sufficient jobs for preventing their starvation and congestion. We empirically evaluate CABS using a benchmark problem of the semiconductor fabrication process, which is a good example of a large-scale network system, in comparison with a well-known traditional manufacturing control method.


virtual environments, image processing, image-based rendering We present a computationally simple and fully automatic method for creating virtual views of a scene by interpolating between three images obtained from different viewpoints. The technique is intended to give an immersive experience and a sense of viewing a real environment. The method uses correspondence points identified in the primary images. The matching of corresponding locations in the images is edge-based and relies on the automatic extraction of suitable epipolar geometries. The resulting edge correspondences are then interpolated and used in an efficient morphing algorithm that operates one scanline at a time to perform image synthesis.


Times Square in New York City was chosen for the new Reuters Headquarters Building for its significance as the crossroads of the world. The headquarters consists of a 30-story office tower with a foundation footprint of 30,000 square feet including two subsurface levels nearly 40 feet deep for retail shops, parking and access to the Times Square subway station. This paper describes the geotechnical challenges that were faced to minimize the effects of both the construction excavation, mainly in mica schist rock, and a new permanent structure on two adjacent landmark theatres, the subway structures, and the streets and utilities of Times Square. Additionally, there could be no interruption of theatre performances or subway service. Engineering solutions included:


Electroactive polymers (EAPs) have attracted a great deal of attention in the last decade due to their unique properties that are applicable to many advanced applications. The present work aims to study the materials–property relationship of this class of materials, and thus facilitate the implementation of EAPs in more applications. The present work investigated the feasibility of adapting cantilever and tubular configurations to the polymeric piezoelectric actuators. The polarization and displacement of samples (fabricated from Poly(Vinyldene fluoride-trifluroethylene) [P(VDF-TrFE)] thin film) were measured under both dynamic and static driving conditions. The polarization loops for all the samples exhibit little hysteresis under weak field and the polarization changes linearly with voltage for most samples. The frequency-dependent polarization behavior is consistent with the previous reported work. The displacements for both cantilever and tubular samples are also noted to be in agreement with the theoretical prediction. Significant displacement (1079 µm) was achieved for samples, even under weak field (60 MV/m). In summary, the results have suggested that the relationship between geometric variables and the performance is also applicable to polymeric materials. Thus, the constitutive relationship can also be applied as a guideline for designing and optimizing the polymeric actuators beyond P(VDF-TrFE) copolymer materials.

Routing is an impact factor for wireless sensor networks (WSN) longevity; in applications like precision agriculture is essential to preserve the sensor nodes lifetime because deployment field (hilly land) location usually does not allow to recharge their batteries. In this paper a genetic algorithm adaptation in order to generate routing trees for WSN in the context of precision agriculture is proposed. The adaptation consists of including in the algorithm parameters from such a context, and of determining by means of experimentation the selection method that is best suited to the solution according to the convergence time of the algorithm


Distant reverberation measurements in the surface/near‐surface and air–sea interaction experiment in the Gulf of Alaska (February/March 1992) were designed to assess the Doppler and spatial characters of primarily low grazing angle reverberation as functions of frequency environmental conditions, and source steering angle. Twenty‐two tests using cw and HFM pulses of 8‐ to 12‐s duration were conducted during a variety of sea conditions, at wind speeds ranging from 4 to 19 m/s. These data were collected simultaneously at two frequencies (usually 250 and 1000 Hz). The data illustrate the contrast in the spectral and temporal characteristics of long‐range reverberation (20 to 30 km) between low sea states where fish scattering is important and higher sea states where subsurface bubbles are important.


The load–deflection relationship of the uniformly loaded rectangular cross-section cantilever is analysed by a modified mechanical model, which exhibits its conformity to the physical situation by considering both the tangential and normal surface stresses. The analytical solution of the modelling equation is solved and presented in terms of the first and the second kinds of the Airy functions in association with Scorer's function. The resultant deflection profile contains an inflection point due to the restoring bending moment contributed by the critical surface loadings. The relationships of the tip deflection and the loading scenario are investigated, which reveal the fact that various loading scenarios can result in different deflection profiles, albeit with the same tip deflection. A numerical algorithm is given in the appendix to solve the loading scenario, by which the surface loadings can formally be determined for the designated applications for the devices utilizing the cantilever structure.

We present the results of a combined investigation of the spectral and kHz QPO evolution around the Z-track in GX 5-1 based on high-quality Rossi-XTE data. In spectral analysis, we find that the Extended ADC emission model provides very good fits to all of the spectra, and the results point clearly to a model for the nature of the Z-track in this source, in agreement with previous results for the similar source GX 340+0. In this model, at the soft apex of the Z-track, the mass accretion rate u M is at its minimum and the neutron star has its lowest temperature; but as the source moves along the normal branch, the luminosity of the Comptonized emission increases, indicating that u M increases and the neutron star gets hotter. The measured flux f of the neutron star emission increases by a factor of ten becoming super-Eddington, and we propose that this causes disruption of the inner disk and the formation of jets. In flaring, the luminosity of the dominant Comptonized emission from the accretion disk corona is constant, while the neutron star emission increases, and we propose for the first time that flaring consists of unstable nuclear burning on the neutron star, supported by the agreement between the measured mass accretion rate per unit area u m at the onset of flaring and the theoretical critical value at which burning becomes unstable. There is a striking correlation between the frequencies of the kHz QPO and the ratio of the flux to the Eddington value: f /fEdd, suggesting an explanation of the higher frequency QPO and of its variation along the Z-track. It is well known that a Keplerian orbit in the disk at this frequency corresponds to a position some distance from the neutron star; we propose that the oscillation always occurs at the inner disk edge, which moves radially outwards on the upper normal and horizontal branches as the measured increasing radiation pressure increasingly disrupts the inner disk.

A biomarker is a substance that is measured and evaluated objectively as an indicator of normal biologicprocesses, pathogenic processes, or pharmacologic responses to a therapeutic intervention. Tooth movementby orthodontic treatment is characterized by remodelling changes in the periodontal ligament, alveolar boneand gingiva. A reflection of these phenomenons can be found in the gingival crevicular fluid (GCF) of movingteeth, with significant elevations in the concentrations of its components like, cytokines, neurotransmitters,growth factors and arachidonic acid metabolites. Knowledge of biomarkers present in the GCF may be ofclinical use leading to proper choice of mechanical stress for betterorthodontic treatment and lesser sideeffects


Human C/EBPe is expressed as four isoforms (32, 30, 27, 14kD) through alternative promoter usage, RNA splicing, and translational start sites. We are studying the C/EBPe isoforms in vivo in cord blood (CB) CD34+ progenitors to define their roles in granulocyte differentiation and hematopoietic lineage specification. The C/EBPe 32/30 isoforms function as transcriptional activators. We reported that C/EBPe 27 interacts with and is a repressor of GATA-1 transactivation of eosinophil-specific genes (Du J et al. JBC2002; 277:43481). C/EBPe 14 , which contains DNA binding and bZIP domains but lacks a transactivation domain, may function as a dominant negative repressor of C/EBPe 32,30 or other C/EBPs through heterodimerization or competition for C/EBP binding sites. We assessed mRNA expression of the C/EBPe isoforms during eosinophil differentiation of CB CD34+ progenitors to determine their temporal patterns of expression. CD34+ progenitors (>95% pure) induced to differentiate into eosinophils by SCF, IL-3, and IL-5 showed differentiation to >90% eosinophils by 17–19 days. Semi-quantitative RT-PCR using C/EBPe isoform-specific primers showed that CD34+ progenitors initially express only the repressor C/EBPe 14 isoform, with induction of all isoforms by day 3 to different peak levels of expression by days 9–11 during the promyelocyte to myelocyte transition. These results define temporal changes in the expression ratios of the C/EBPe activator vs. repressor isoforms during eosinophil development that may differentially regulate gene transcription in this process. We subcloned the C/EBPe isoform cDNAs into an MSCV-based bicistronic retroviral vector (pGCDNsam IRES-EGFP) and ectopic expression was induced in CB CD34+ progenitors by retroviral transduction for 72hrs. The CD34+/GFP+ cells were sorted by FACS and plated in Collagen Cult™ media containing SCF, IL-3 and a lineage-specific cytokine (i.e. EPO, G-CSF, or IL-5), or in suspension culture containing SCF, IL-3 and IL-5 to drive eosinophil differentiation. Total and differential colony and cell counts were performed after 15–17 days based on colony morphology, histochemical and enzyme staining of the cells. The activator C/EBPe 32 isoform significantly altered myeloid development, favoring eosinophil over neutrophil or erythroid development. Even in cultures containing EPO, cells transduced with C/EBPe 32 failed to develop into erythroid colonies (BFU-E). C/EBPe 27 , a potent repressor of GATA-1 in vitro, inhibited erythroid colony growth by ~50%, and doubled the numbers of granulocyte-macrophage colonies compared to C/EBPe 14 or empty vector control. C/EBPe 32 strongly induced eosinophil colony formation at the expense of neutrophil other myeloid lineages regardless of the cytokines used, inducing ~90% eosinophil colonies. C/EBPe 27 reduced eosinophil colonies by >50%. Likewise, >90% of cells transduced with C/EBPe 32 and grown in suspension culture were eosinophils, whereas C/EBPe 27 and C/EBPe 14 inhibited eosinophil differentiation by ~50% and >98%, respectively. Thus, the C/EBPe isoforms: (1) are differentially expressed during eosinophil development, (2) have the capacity to reprogram stem cells to different myeloid lineages consistent with their predicted activator vs. repressor activities and interactions with hematopoietic transcription factors such as GATA-1 or other C/EBPs, and (3) may be useful in their ability to reprogram myeloid terminal differentiation for the development of novel approaches to treat myeloid or other leukemias.


Mental health is important for college students to be able to complete their academic assignments properly. In final year college students, Skripsi can be one of the causes of mental health problems. The purpose of this study was to describe emotional mental health in level 4 students of the Bachelor of Nursing Stikes Karya Husada, Kediri. This research is a quantitative research with descriptive analytic method. The population of this study were 4th level students of the Bachelor of Nursing Study Program Stikes Karya Husada Kediri, totaling 89 students. The sampling technique used was purposive sampling with 46 students as respondents. Data was collected using the SRQ 20 questionnaire which consisted of 20 question items for the detection of emotional mental health problems. Early detection of emotional mental health problems for students needs to be done to anticipate the occurrence of mental disorders due to the inability of students to cope with existing stressors.


Hiatus herniae are commonly seen at endoscopy. Many patients with a large hiatus hernia are endoscoped for symptoms associated with the hernia and many of these will progress to surgical treatment. However, little is known about the natural history of small to medium size hiatus herniae, and their risk of progressing to a larger hernia requiring surgery. This study aims to determine the need for subsequent surgery in these patients.


This paper presents a simple circuit for measuring differential resistance variations. The Wheatstone Gadget, or The Gadget, is able to measure the same parameters as the Wheatstone Bridge in combination with an emitter-coupled pair [1], but with fewer components and fewer supply voltages. The Gadget is a simple circuit with a lot of possibilities, as shown in this paper. It needs only one power supply and is especially designed for small resistor values, which makes it well suitable for micromechanical applications.


The purpose of this study was to investigate the most prevalent critical thinking skills among 10th grade students enrolled in the public schools in the kingdom of Bahrain. It involved investigating the relationship between critical thinking skills and level of academic achievement and gender. The sample of this study consisted of (337) quasi-randomly selected Bahraini high school students, (149) males and (188) females.

Despite the vast amount of research on morphemes and literacy, examination of how morphemic analysis affects secondary language learners is limited. Morphemic analysis is the process of using common Latin and Greek prefixes, roots and suffixes to hypothesize the meaning of unknown vocabulary. The primary purpose of the research is to determine how morphemic analysis affects English learners ability to determine the meaning of unknown academic vocabulary in their high school advanced placement geography class. The secondary purpose of the study is to provide secondary teachers a tool to do something about the vocabulary gap they observe between native speakers of English and English learners. Many English learners struggle to access academic texts in their secondary classes while many teachers focus on tier three high impact vocabulary words from their respective content areas. Despite the best efforts of secondary educators, students are left dependent on their teachers for accessing academic texts. This study explores the possibility of teaching students how to teach themselves academic vocabulary by using morphemic analysis. The methodology of the intervention period explicitly teaches a group of students the eight most common prefixes, roots and suffixes from their classroom textbook. Data from a pretest, post-test, and exit survey are used to analyze the effects of morphemic analysis. Results from the study indicate that morphemic analysis aids students ability to comprehend unknown academic vocabulary however, variation of data implies that some participants found the method more helpful than other participants.


The Texas LoanSTAR Monitoring and Analysis Program (MAP) is responsible for monitoring energy conservation retrofits at various sites throughout Texas. An important part of this task is gathering pertinent energy consumption and weather data for the site to determine the effectiveness of the retrofit projects. For this purpose, LoanSTAR researchers have installed dedicated data loggers at over 30 retrofit sites. These devices are designed specifically to collect energy and/or weather data from appropriate sensors, store them, and transmit them via a telephone modem when polled, a task they perform quite well. Although data loggers have proven effective in the data gathering process, it has been observed that many of their functions may be accomplished by Energy Management and Control Systems (EMCSs). While it is obvious that an EMCS should not be installed strictly for monitoring energy usage, an existing EMCS may provide an alternative monitoring solution to the installation of a dedicated data logger in sites so equipped. The purpose of this project is to determine the monitoring capabilities of various EMCSs, and to identify advantages and disadvantages of utilizing existing systems for energy monitoring at LoanSTAR sites.


The spectral performance of a demultiplexer is significantly affected by the phase and amplitude errors due to fabrication errors. We estimate the impact of fabrication errors on a flat-top grating-based planar waveguide demultiplexer using a design example. Simulation results show that the photomask resolution resulting in a phase error should be lower than 40 nm when a crosstalk criterion of -30 dB is given. The impact of amplitude errors is not distinct until the reduced amount of the facet width is greater than 0.5 µm and the grating side-wall angle offset from the vertical is larger than 1°.


In the same way as between humans, eye contact between humans and robots (especially androids) is an important element in nonverbal communication. To achieve eye contact in androids, we need to control the android's gaze to follow the planned trajectory. To do this, we have to estimate the relationship between the gaze direction and the input values of the actuator controller in an android's eyes. We call this estimation gaze calibration. In this paper, we propose a gaze calibration method for an android using a single camera as the gaze direction target in order to accurately adjust the android's gaze. First, we estimate the android's gaze direction from the orientation of its head and the camera, only using the relationships between each coordinate system. Second, we create datasets to estimate the parameters of the modeled relationship. We also propose a method to evaluate the effectiveness of the gaze calibration method. For the evaluation, we compare the subjects' perception of the calibrated android's gaze with a human gaze. Experimental results with this evaluation method show that the gaze calibration method makes the android's eye contact similar to a human gaze control for most of the test cases.


During electrolysis, to visually observe the conversion of a metal to its cation, either the cation or its complex ion should have a distinct color while the electrolyte solution must be colorless and transparent. A demonstration is described in which copper is used as the electrodes and sodium polyacrylate (a superabsorbent polymer) solution is used as the electrolyte in an electrolytic cell. Dissolution of copper ions from the copper electrode, migration of copper ions from the anode toward the cathode in the electrolyte solution, and deposition of copper metal on the cathode can be observed simultaneously. This demonstration is useful for teaching high school and first-year college students about electrolysis.


Background: Intensive care is a universal professional key competence for doctors of all specializations. Preventive care, early detection and timely correction of precursors, life-threatening symptoms and complications, are its structural components that must ensure capabilities and readiness to diagnose acute pathologies and to provide efficient treatment for patients in critical conditions. It requires complex professional skills, know-hows, attitude and working experience which must be created by professional educational systems, focused on both near- and long-term outcomes for patients. Purpose: To increase effectiveness of medical education by improving related technologies and methodologies. Materials and Methods: Contemporary interactive education in cardio-respiratory resuscitation and intensive care for medical interns of all specializations which was improved in line with recent development of intensive care technologies and devices for patients' monitoring and life support.

Cells are not created equal. The Human Cell Atlas (HCA) project aims to build atlas of all human cell types and cell states with their molecular signatures. It is a fundamental step toward the comprehensive understanding of the human body, the super-complex system composed of tens of trillions of cells that are all developed from a single cell. Single-cell sequencing especially single-cell RNA-sequencing (scRNAseq) is the key technology for obtaining the molecular signatures of a large amount of single cells at the whole transcriptome scale. Other single-cell omics technologies including single-cell ATAC-seq, single-cell methylation sequencing, single-cell Hi-C as well as in-situ technologies like single-cell spatial transcriptomics are also under rapid development. Such single-cell technologies convert each cell to a mathematical vector in the high-dimensional spaces of the gene expression and other omics features. Therefore, computational analyses become the key component of all HCA studies. This talk will give an overview on some major bioinformatics challenges in this field, and present examples of our on-going work on new methods for differential expression analysis and dimension reduction.

The article analyses anomalies in the Qumran tefillin corpus, the earliest archaeological evidence for the practice, in the light of which I argue that tefillin originated as 'length-of-days' amulets. These anomalies and other features of Qumran tefillin are also explained, with reference to this hypothesis, against the backdrop of comparative evidence for ancient amuletic ritual. A popular / private model for tefillin practice is highlighted, and I additionally argue that the etymology of the word 'tefillin' reflects the objects' function as a prayer in material form. 1 conclude that tefillin were indeed protective amulets, i.e. phylacteries, calling into question the implications of this finding for the Jewish encounter with Hellenistic religion. In an appendix 1 bring the Qumran mezuzot into the picture, suggesting that these may in fact have been tefillin, and that they are in any event support for my argument.

We analyze the effects of antitrust and leniency programs in a repeated oligopoly model outlined in Motta and Polo (2003). We extend their framework by including the possibility of Type I judicial errors and pre-trial settlements. Through comparison of our results to the earlier results we come to a number of novel conclusions. Firstly, antitrust enforcement in the presence of judicial errors is less effective and ex-ante deterrence is weaker than was predicted by Motta and Polo (2003). Secondly, adverse effects of leniency programs are underestimated by the traditional approach, which does not take Type I judicial errors into account.


This contemporary work unveils the usage of a new methodology to carry out an accurate hazard mapping of urban flood footprints. It is based on wetness transformation. It is a procedure of conversion of multi-spectral-bands into three dimensional feature space. The present study embraces conversion of thematic mapper (TM) imagery of Landsat to a three dimensional array; brightness, wetness and greenness, followed by the technique of change detection to locate inundated areas in urban regions. Efficient thresholding of the normalized difference image generated during change detection has shown promising results in identifying the flood extents which include standing water due to flood and mud surge caused by the flood. Prior to wetness transformations, dark object subtraction has been used in lower wavelengths to avoid errors due to scattering in urban areas. The study shows promising results in eliminating most of the problems associated with urban flooding like misclassification due to presence of asphalt, scattering in lower wavelengths and delineating mud surge. The methodology is implemented over Noida, business capital of state of Uttar Pradesh, India and tested on September 1980 flood event. The results are validated by satellite imageries on Google Earth to bolster the methodology of accurate extraction of urban flood footprint.

The layout of an efficient construction site to ensure a congenial working space and to store, transport and deliver material and equipment and to and in the best and safest manner and within the shortest time belongs to leading factors and requirements in a complex construction project. The parametric modelling involves benefits for automated generation of alternatives of production area layout to select suitable one. The methodology of interactive parametric modelling of construction site layout in 3D is presented and described in the paper. The methodology represents the foundation concept of 3D software tool for construction site layout designing through Information and Communication Technology. Moreover, the paper deals with a system of interactive parametric modelling of the construction site layout in 3D based on the study of the topological properties of construction site facilities. The creation of the proposed methodology has been conditioned by defining the mentioned system. Both, direct and indirect parameters, to be integrated into the interactive programming system of construction site layout, are specified and discussed.


Nodular regenerative hyperplasia of the liver is characterized grossly by diffusely nodular liver resembling micronodular cirrhosis. Viewed microscopically, the nodules consist of regenerative parenchyma without fibrosis, which are usually smaller than the hepatic lobule. Nodular regenerative hyperplasia is distinct from other nodular lesions of the liver such as cirrhosis, partial nodular transformation, focal nodular hyperplasia, and adenoma. Although nodular regenerative hyperplasia is seldom reported, it may occur more frequently than it is recognized.


By using Discrete Element simulations, we study the bulk properties of bidisperse granular mixtures. We focus on the role of the size ratio between components and show that the effective bulk modulus of a granular (base) assembly can be enhanced by up to 20% by substituting as little as 5% of its volume with smaller radius particles. Using particles of a similar size barely affects the average bulk properties of the assembly. On the other extreme, when a huge number of very small particles are included, most of them lie in the voids of the base material, acting as rattlers, leading to an overall weakening effect. In between the limits, for dense systems, an optimum size ratio that maximizes the bulk modulus of the mixture can be found. Conversely, loose systems always get weaker since more and more small particles become rattlers. Finally, we relate the mixture properties with the 'typical' pore size in a disordered structure as induced by the combined effect of operating volume fraction and size ratio.


Integer-programming formulations for the design of symmetric and balanced laminated plates under biaxial compression are presented. Both maximization of buckling load for a given total thickness and the minimization of total thickness subject to a buckling constraint are formulated. The design variables that define the stacking sequence of the laminate are zero-one integers. It is shown that the formulation results in a linear optimization problem that can be solved on readily available software. This is in contrast to the continuous case, where the design variables are the thicknesses of layers with specified ply orientations, and the optimization problem is nonlinear. Constraints on the stacking sequence such as a limit on the number of contiguous plies of the same orientation and limits on in-plane stiffnesses are easily accommodated. Examples are presented for graphite-epoxy plates under uniaxial and biaxial compression using a commercial software package based on the branch-and-bound algorithm.


Members of the (Li1.3-yCuy)V3O8 solid solution were synthesized for 0 < y < 1 by annealing, in evacuated sealed quartz ampules, stoichiometric mixtures of LiVO3, Cu2O, and V2O5, and their electrochemical performance in (Li1.3-yCuy)V3O8/Li cells was studied as a function of y. The rationale for carrying out such a synthesis in a vacuum rather than in air, as commonly practiced, is given, and the origin of the Cu solid solution limit is explained on the basis of structural considerations. With the exception of the rate capability, the electrochemical performances of the (Li1.3-yCuy)V3O8 samples both in terms of capacity and capacity retention decreased with increasing y. The decrease in reversibility of the Li insertion/deinsertion process with increasing y is shown, through in situ X-rays and HRTEM measurements, to be nested in the partial reversibility of the Cu extrusion/re-injection process on cycling.

Lack of complete distribution calls for stochastically robust models that, after exploiting available limited or partial information, offer risk-shielded solutions, or in other words, solutions that are insensitive to all possible distributions of random variables. We focus on the well-known newsvendor problem in this study, where the distribution of the random demand is only specified by its mean and one of the following: its standard deviation or its support. We propose a stochastically robust model for the newsvendor problem. More specifically, our model tries to minimize the regret that is defined as the ratio of the expected cost based on limited information to that based on complete information, called Relative Expected Value of Distribution (REVD). We show how to derive an optimal solution to the REVD model. Numerical examples are provided to compare our model with other similar approaches. The goal is to establish a confidence ratio that the decision from our model is not worse, relatively, too much than the decision based on the true distribution which would be never known exactly in real-world applications.


A walkthrough evaluation and worker interviews were carried out on August 7, 1985 at Champion DairyPak, Morristown, New Jersey. The evaluation was requested by UAW Local 260 to investigate health hazards at the facility. Approximately 135 workers are employed on three shifts printing and folding plastic impregnated cartons used for dairy products. The primary potential exposures at Champion DairyPak are considered to be noise, solvents and polyethylene dust. Fifteen workers on the first shift were questioned concerning respiratory symptoms that might be related to dust exposure; four reported symptoms associated with an irritant dust during sealing-machine clean-up procedures. The noise problem was evaluated by the company, and a hearing-conservation program is in place. The company had previously replaced the solvbent 2-ethoxyethanol with propylene-glycol-monomethyl-ether to reduce potential health risks of exposure. The authors concluded that minimal health hazards exist at Champion DairyPak due to exposure to dusts from the sealing machines and solvents in the printing process. Recommendations are made to reduce exposures to solvents and dusts, and to reduce noise levels in the facility.


The microchannel heat exchanger is one of the most compact and effective heat exchangers used for cooling devices in building air conditioning system, while application of nanofluids in microchannel further enhance its thermal performance due to its much higher thermal conductivity. Considering the continuous rapid increase in energy consumption in the building sector, especially in air conditioning systems, the heat transfer performance of a microchannel with nanofluids should be further enhanced to realize energy savings. This study analyzes the influence of combining nanofluid and flow disturbance structure on the heat transfer enhancement of a microchannel, which is also the noted novelty. A rectangular grooved microchannel (RGMC) is proposed, and its thermal performance using Al2O3/water nanofluids is investigated using the CFD method, with the mixture model to simulate the Al2O3/water nanofluids considering the slip velocity between the base fluid and nanoparticles. The results show that at 1.5 m/s, Nu of RGMC with 2 vol% nanofluids is 38.5% larger than that of smooth microchannel (SMC) with the same nanofluids, and 36.7% larger than that of RGMC with pure water, indicating the much better heat transfer performance of the novel designed RGMC structure. The maximum temperature for RGMC is 5 K lower than SMC with 2 vol% Al2O3/water nanofluid at inlet velocity of 1.5 m/s. Further analysis on the integrated effect between fluid flow and heat transfer shows that the synergy angle β near the center line of RGMC is much lower than that of SMC, representing that the better thermal performance is caused by the flow structured induced by the grooves. Moreover, at 1.5 m/s, βα of SMC with 2 vol% nanofluid is 89.4 Deg, which is 1.66 Deg higher than the βα value of RGMC, while at 0.25 m/s, the βα of two types of microchannel are close to each other. This indicates that the groove structure shows greater enhancement at higher inlet velocity. It is concluded that combining nanofluid and groove structure can significantly enhance heat transfer of the microchannel. The nanofluid enhances heat transfer at lower inlet velocity, while the groove structure enhances it at higher inlet velocity. This study will be helpful for the design of a high-efficiency microchannel heat exchanger that promotes building energy savings.

Submitted for the DFD11 Meeting of The American Physical Society Particle Impaction for Trace Contaminant Detection in a VeryHigh-Volume Airstream MATTHEW FULGHUM, MICHAEL HARGATHER, GARY SETTLES, Pennsylvania State University — An impactor with automated thermal desorption has been designed and tested for airborne trace contaminant detection in a veryhigh-volume airstream, up to one cubic meter per second. This airflow is scanned for contaminants using an ion mobility spectrometer, which is flow rate-limited to ∼ 10 cc s . As the chemicals of interest, once impacted, are capable of being thermally desorbed and interrogated as a vapor, a novel method of collecting these particles was devised. A 0.3m long linear-slot impactor is used to concentrate particles upon a periodically-heated notch of equal length in a rotating rod. After impaction, this rod is rotated into the interrogation position and is heated to thermally desorb the impacted particles into the carrier-gas flow as a vapor. This flow is several orders of magnitude smaller than the primary airstream being sampled and carries a heavy concentration of the desorbed vapor from the impacted particles to subsequent chemical analysis by the IMS, improving contaminant detection without overwhelming its flow rate capabilities.

The total number and length of new shoots of Leucothoe catesbaei Gray were significantly greater, and the plants were of better quality with NO3 nutrition than with NH4 or urea nutrition. Especially with the NH4-N sources, growth was as good as or significantly greater at pH 6 to 7 than at 4 to 5. The total number and length of new shoots of Rhododendron catawbiense Michx. cv. Roseum Elegans were not significantly affected by the N source or pH, although plant appearance was significantly better with NO3 nutrition than with NH4 or urea nutrition. The nitrification inhibitor, a substituted pyridine, had no significant effect on the growth and development of either leucothoe or rhododendron.
