In The Disinformation Age, editors W. Lance Bennett and Steven Livingston assemble a distinguished group of interdisciplinary researchers to examine the contemporary scourge of politically motivated disinformation in civil society. They sustain a novel, coherent argument throughout (which is, in itself, an unusual feat for an edited volume). That argument, in a nutshell, is that the foremost engineers of American "truth decay" are capitalists and capitalism. Bennett and Livingston summarize the case in chapter 1, describing how a network of libertarian ideologues bankrolled a systematic effort over several decades to dismantle public trust in informational authorities and other public institutions (e.g., peer-reviewed science, higher education, the mainstream media, and nonpartisan government agencies). Chapters 4 (by Naomi Oreskes, Erik M. Conway, and Charlie Tyson) and 5 (by Nancy MacLean) further this argument, homing in on the efforts of mid-century business interests (chapter 4) and the Koch family (chapter 5). This is important because, as various contributors to the volume point out, if there is no shared public trust in informational authorities, there can be no shared public truth either—which opens the door for propagandists to take advantage. Other chapters focus blame on the unfettered free market itself. They point to the deregulation of political communication in particular, which has produced an asymmetrical right-wing echo chamber of persistent, reinforcing deception (chapter 2, by Yochai Benkler) and a "flooded zone" of degraded digital information sources that distract, stupefy, overwhelm, and polarize the body politic (chapters 3, by Paul Starr, and 6, by Dave Karpf). Much of the volume is devoted to exploring potential remedies. In chapter 6, Dave Karpf calls on online media giants, political elites, and the legacy press to regulate/ monitor themselves, whereas in chapter 7, Heidi Tworek draws historical lessons from Germany's Weimar Republic to advocate reforms designed to fortify democracy. In chapter 8, Ben Epstein explains why regulating disinformation is so challenging and offers a set of standards for doing it judiciously. Chapters 9 (by Patricia Aufderheide) and 10 (by Victor Pickard) make the case for an expanded and redesigned model of public broadcasting as a bulwark against disinformation. Finally, in chapter 11, Bennett and Livingston call for tax reforms that would remove protections for faux-philanthropic organizations whose mission it is to undermine democratic institutions. The volume's pragmatic devotion to offering potential solutions is a real strength. Several of those proposed solutions—campaign finance reform, tax reform, other democratic reforms—are well worn in other contexts, but they are novel as applied to this context (at least as far as I have seen). The ideas for strengthening public broadcasting, in my view, were particularly compelling. The Disinformation Age also succeeds as history, providing rich narratives of how political communication has evolved over the past 50 years, and of how libertarian political mobilization emerged and matured. In so doing, the volume may find more of an enthusiastic audience among historians than political scientists, the latter of whom tend to prefer more data-driven accounts (such as that in chapter 2, by Yochai Benkler). The volume's interdisciplinary approach is another selling point. By bringing together scholars of communication, politics, history, sociology, international affairs, public policy, and even geology and literature(!), Bennett and Livingston have organized a remarkable collaboration of diverse intellectual perspectives. As I alreadymentioned, some readers will surely yearn for more social science, but the scholarly breadth of the volume's contributors is undeniably noteworthy and commendable. The best part of The Disinformation Age, though, is the argument itself. Criticism of the "Kochtopus" and others— and of the underlying laissez-faire system such libertarian ideologues protect—is not new. But I have not seen such a systematic critique applied to the "post-truth" crisis, specifically. In the wake of standard explanations emphasizing (1) the tools of disinformation (partisan media, online media, social media) and/or (2) the static psychology of motivated reasoning, the focus on political economy in this volume feels fresh. Rather than ignoring or dismissing the customary explanations, the authors incorporate them as elements of their broader thesis. Of course, this leftist critique is sure to encounter pushback from neoliberals at the American Enterprise Institute, the Cato Institute, the Wall Street Journal, the Chamber of Commerce, and others, not to mention the business community more generally. The free-market devotees, who have sought to distinguish their brand of ideological conservatism from its more recent populist/ Trumpist/insurrectionist manifestation—even locking arms with center-left groups in rhetorically rejecting the nativistic, nationalistic, nihilistic, and anti-intellectual tendencies of the New Right—must confront in these pages the possibility that they contributed to the problem. Such provocativeness on the part of Bennett, Livingston,


Abstract. The absorption and luminescence spectra of the R1 and R2 bands in a ruby Al2O3:Cr3+ (0,05%) single crystal at room temperature were studied. The luminescence bands have been obtained both by excitation of the crystal by the radiation of a halogen lamp and by selective excitation of the two upper levels of the 2T1 state using the radiation of a laser diode with a tunable wavelength (656-662 nm). In the spectra of selectively excited luminescence bands, four different displacements of the R1 and R2 bands and four different distances between these bands have been detected, the change of which is a multiple of ~ 0.52 cm-1. A detailed comparative analysis of the obtained spectra of the luminescence bands and their absorption allowed us to determine the combined structure of each of the R1 and R2 bands, formed by additional doublets of these bands of all four stable isotopes of ions 50Cr3+, 52Cr3+, 53Cr3+ and 54Cr3+. The splitting of the obtained doublets varies from 7.04 to 9.14 cm-1 depend on the mass of the isotope

This paper investigates the use of Facebook for out-of-class, informal language learning. 190 New Zealand university language students (Chinese, German, French, Japanese and Spanish) completed an anonymous online questionnaire on (1) their perceptions of Facebook as a multilingual environment, (2) their online writing practices and (3) their views on the educational value of their experiences. Findings indicate that language students are using a range of Facebook features to expose themselves to the languages they study (L2) and to communicate in their L2 with native speaker Facebook friends. The use of the social networking site varied according to proficiency-levels of the participants (beginner, intermediate and advanced levels), strength of social ties with native speaker Facebook friends and personal attitudes towards the site. Learning experiences on Facebook were not perceived as useful for the formal language learning context which suggests the need for bridging strategies between informal and formal learning environments.

Objective To study the safety of tilt table test (TTT) in elderly patients. Methods Among the 785 subjects examined for TTT, 110 were elders with an average age of( 65±4) years, ranging from 60 to 82. Out of the 110 elder subjects, 39 syncope patients were due to unknown reasons, 13 due to heart or brain diseases and 58 were non syncope subjects. We conducted base tilt table test (BTTT) in all patients and additional isoproterenol tilt table test (ITTT) in 18 patients. The BTTT protocol included 60~80 degrees upright tilt for 25 minutes and the ITTT protocol included isoproterenol infusion at 2-4 μg/min for 10 minutes. Results 13 out of 39 patients with unknown reasons had a positive BTTT and 6 out of 10 patients had a positive ITTT, respectively; Among the 31 out of 110 positive TTT patients, 17 (54.8%) showed a vasodepressor response, 4 (12.9%) a cardioinhibitory response and 10 (32.3%) mixed response. Serious abnormal responses were not observed. Conclusions (1) TTT is a safe and effective method for diagnosing the vasovagal syncope (VVS) in elderly patients; (2) Because of its safety, BTTT could be chosen for identifying the VVS in the elderly heart or brain disease patients complicated with syncope.


The article presents the results of a systematic analysis of the process of integration of Russian youth into the political sphere of society. The specificity of the situation of young people as an object and subject of state policy is justified and the conditions for stimulating their socio-political activity are revealed. The orientation of the participation of the younger generation in the political process of the country is influenced by an integrated system of political, socio-economic, historical and cultural factors. The conclusion is argued that the situation of the young generation, the formation and realization of its socio-political potential continue to remain controversial. The productive realization of its innovative potential is a significant factor in political progress.

ZnO powder nanoparticles were doped with iron (mixing produced by mechanical alloying). Their structure, microstructure and magnetic properties were investigated by X-ray diffraction (XRD), scanning electron microscopy (SEM) and vibrating sample magnetometry (VSM). ZnO starting pure powder exhibits a hexagonal crystal structure with space group P63mc. Otherwise, with the addition of 1% Fe in the ZnO milled powder, the hexagonal ZnO phase remained unchanged, whereas the microstructural parameters were subject to significant variations due to the introduction of Fe atoms into the ZnO hexagonal matrix to replace oxygen ones. The size of crystallites and microstrains were milling time-dependent.


A free-space optics mode-wavelength division multiplexing (MWDM) system using Laguerre-Gaussian (LG) modes is designed using decision feedback equalization for controlling mode coupling and combating inter symbol interference so as to increase channel diversity. In this paper, a data rate of 24 Gbps is achieved for a FSO MWDM channel of 2.6 km in length using feedback equalization. Simulation results show significant improvement in eye diagrams and bit-error rates before and after decision feedback equalization.


Deepwater fish populations are often characterized by their life-history as being highly susceptible to overexploitation. Moreover, dependent fisheries often develop rapidly, so overexploitation may occur before resource dynamics are quantified sufficiently to assess safe biological limits. It is therefore crucial to employ assessment methods that make the best use of limited data and management procedures that account for large uncertainties. This review provides a critical synthesis of assessment and management approaches for deepwater fisheries. Given limitations in the data, it is clear that assessments are likely to benefit from the application of derived relationships between life-history characteristics and the sharing of this and other information across stocks. It is important that uncertainty in assessment results is represented adequately, and management methods must in turn ensure that decision mechanisms are robust to an incomplete picture of resource dynamics. This requires construction and testing of harvest control rules within a simulation framework. Harvest control rules themselves, however, need not be complicated, and simple empirical approaches can be adequate for situations in which only relative changes in biomass can be discerned from the data. Development and testing of these control rules is likely to prove a productive area of future research.


To the many thousand colored teachers in our country this book is dedicated. During my experience of eleven years as a teacher, I have often felt that the children of the race ought to study some work that would give them a little information on the many brave deeds and noble characters of their own race. I have often observed the sin of omission and commission on the part of white authors, most of whom seem to have written exclusively for white children, and studiously left out the many creditable deeds of the Negro. The general tone of most of the histories taught in our schools has been that of the inferiority of the Negro, whether actually said in so many words, or left to be implied from the highest laudation of the deeds of one race to the complete exclusion of those of the other. It must, indeed, be a stimulus to any people to be able to refer to their ancestors as distinguished in deeds of valor, and peculiarly so to the colored people. But how must the little colored child feel when he has completed the assigned course of U. S. History and in it found not one word of credit, not one word of favorable comment for even one among the millions of his foreparents, who have lived through nearly three centuries of his country's history! The Negro is hardly given a passing notice in many of the histories taught in the schools; he is credited with no heritage of valor; he is mentioned only as a slave, while true historical records prove him to have been among the most patriotic of patriots, among the bravest of soldiers, and constantly a God-fearing, faithful producer of the nation's wealth. Though a slave to this government, his was the first blood shed in its defence in those days when a foreign foe threatened its destruction. In each of the American wars the Negro was faithful  yes,


In order to improve the effect of military propaganda to Taiwan, we should proceed from actual conditions of the situation between the two sides of the Strait and the actual conditions of propaganda audience. We should have a strong sense of principle and strengthen the propaganda aim on the military propaganda to Taiwan. Furthermore, we should also regard for its artistic quality to enhance the acceptability of the propaganda information.


: Medicinal plants play a predominant role in curing and preventing disease due to their antibacterial and antimicrobial activity against Human microorganism. The aim of present work is to formulate and evaluate antibacterial mouthwash and evaluate its effectiveness against microbes present in oral cavity. They act on mouth pathogens, microbes and reduces the pain and also has no more side effects. The various herbs and their extracts such as Tulsi, Green tea, Nagarmotha were selected for mouthwash and prepared formulation was further screened for antimicrobial activity against culture and further evaluated for physical properties. The presence mouthwash possesses a good antibacterial property. This solution can be used to reduce the microbial growth in the oral and may also be given for other reason like for analgesic action, gingivitis, anti-inflammatory activity.


Background:
 A systemic inflammatory state caused by comorbidities has been shown to play a key role in pathophysiology of heart failure with preserved ejection fraction (HFpEF). The inflammation-based prognostic score termed Glasgow prognostic score (GPS), combining C-reactive protein and albumin, has been reported to provide prognostic information in patients with cancer or heart failure. However, little is known about the usefulness of the GPS for the prediction of prognosis in patients with HFpEF who are admitted with acute decompensated heart failure (ADHF).

 Methods:
 Patients' data were extracted from The Prospective mUlticenteR obServational stUdy of patIenTs with Heart Failure with Preserved Ejection Fraction (PURSUIT-HFpEF) study, which is a prospective multicenter observational registry for ADHF patients with LVEF ≥50% in Osaka area. We studied 1017 patients who survived to discharge. The GSP was calculated at discharge as follows: patients with both elevated C-reactive protein (>1.0mg/dL) and hypoalbuminemia (<3.5g/dL) were allocated a score of 2, patients with one of these abnormalities were allocated a score of 1, and patients with neither of these were allocated a score of 0. The endpoint was all-cause death.

 Results:
 During a follow-up period of 1.5±1.2 years, 178 patients had all-cause death. At multivariate Cox analysis, GPS 1 (hazard ratio [HR] 1.71, 95% confidence interval [CI] 1.14-2.56, p=0.0090) and GPS 2 (HR 2.42, 95% CI 1.51-3.88, p=0.0003) were independently associated with all-cause death after the adjustment for major confounders. There was significant difference in the rate of all-cause death when the patients were stratified according to the GPS (Figure).

 Conclusions:
 In this multicenter study, the systemic inflammation-based GPS was shown to be useful for the prediction of prognosis in HFpEF patients admitted for ADHF.


It has been reported that the normal epithelium of the anterior nares is covered by a mucopolysaccharide layer with a depth of approximately 0.8μ1. In the present study, a patient with an allergy to the Japanese cedar was found to develop a very thin mucopolysaccharide layer (0.05μ in depth) when the mucosal tissue was taken off before provocation. Adhering pollen particles could have readily come in contact with the plasma membranes of the epithelial cells. The epithelium of the nonciliated cells exfoliated in a relatively short period of time after provocation. Ten minutes after provocation, a thick mucus layer covered the exfoliated epithelial mucosa. Pollen particles could no longer be brought into contact with mucosa due to the mucus layer. On the other hand, no difference from the normal condition was seen before provocation in the middle and posterior nares where ciliated cells were located. However, at ten minutes after provocation, a large number of goblet cells appeared in place of ciliated cells, and mucus production was very much activated. Many signs appeared at this stage which suggested the impairment of ciliary beating. Specifically, there was swelling and damage of plasma membranes of cilia, bending of cilia, existence of extra cytoplasm around the microtubules in the cilia, and intrusion of mucus fluid between cilia. In the regions where ciliated cells were replaced by goblet cells, the exfoliation of epithelium could be noted, but it is generally difficult to find that ciliated cells are exfoliated even when the ciliary beating is impaired. Taking into account the above-mentioned results, it can be assumed that pollen particles penetrate the submucosa not only through the posterior nares where ciliary beating is impaired, but also through the anterior nares where epithelial cells are exfoliated.

We address the problem of determining the parameters of a traffic shaper modeled as a single server queue with finite buffer size and deterministic service rate. In our scheme, the user wishes to gain access to the network with cell loss probability guarantees when the input traffic is self-similar. We assume that the mean rate, the variance and the degree of self-similarity are known. The network is able to provide a connection if the user voluntarily shapes the traffic and if sufficient resources are available to accommodate the shaped traffic stream. We formulate a minimization problem to determine the optimal parameters for the traffic shaper and use techniques of non-linear programming to obtain a solution.


Alzheimer's disease is a condition that leads to, progressive neurological brain disorder and destroys cells of the brain thereby causing an individual to lose their ability to continue daily activities and also hampers their mentality. Diagnostic symptoms are experienced by patients usually at later stages after irreversible neural damage occurs. Detection of AD is challenging because sometimes the signs that distinguish AD MRI data, can be found in MRI data of normal healthy brains of older people. Even though this disease is not completely curable, earlier detection can aid in promising treatment and prevent permanent damage to brain tissues. Age and genetics are the greatest risk factors for this disease. This paper presents the latest reports on AD detection based on different types of Neural Network Architectures.


To determine the evolutionary origin of GCRP and GCRPR and the relationship between their gene families, we analyzed the synteny of GCG-related peptide and receptor genes in the genomes of a variety of vertebrate species. In particular, we analyzed four tetrapod representatives (human, anole, chicken, and Xenopus) and four teleost representatives (zebrafish, medaka, tetraodon, and stickleback). Genome synteny analyses were performed by comparing Contig Views of the genomic regions containing the GCG-related peptide and receptor loci. Chromosomal localization of orthologs or paralogs of neighboring genes was obtained from the Ensembl Genome Browser. According to the method of Yegorov and Good (2012), chromosome fragments with reliable synteny were matched with the reconstructed protochromosome models by Nakatani et al. (2007) (herein referred to as the N-model). The origins of the fragments were traced from the gnathostome ancestor chromosome (GAC), which contained linkage groups for the hypothetical post-2R ancestor of jawed vertebrates (Nakatani et al., 2007). In the N-model, 40 reconstructed GACs (A0-J1) are derived from 10-13 vertebrate pre-2R ancestral chromosomes (VAC), the A-J linkage groups (Nakatani et al., 2007). The N-model provides conserved vertebrate linkage blocks that are displayed along individual human chromosomes, indicating the locations of human ohnologs and orthologs of medaka, chicken, and mouse (Nakatani et al. 2007). Thus, we were able to compare the chromosome fragments with linkage groups shown for each chromosome of the three taxa (human, chicken, and medaka) to resolve the positions of the gene blocks at consecutive stages of vertebrate genome evolution (e.g., pre-2R VAC and post-2R GAC).


A collection of some of Osborne's early plays, as well as his last, Dejavu, which features Jimmy Porter of Look Back in Anger, 35 years on, older and wiser, but no less indignantly eloquent."


Pitting potentials of zircaloy-2 in artificial seawater were measured as a function of chloride concentration or solution temperature with and without gamma-ray irradiation. The corrosion potentials of zircaloy-2 were also measured over 720 h. The pitting potential with gamma-ray irradiation was slightly greater than that without the irradiation. In both cases with and without the irradiation, the corrosion potentials of zircaloy-2 did not exceed the pitting potential. The pitting potential under irradiation was decreased with increasing chloride concentration and/or solution temperature.


The rate of combination of methyl radicals produced by the thermal decomposition of mercury dimethyl has been studied with a free radical mass spectrometer over a large range of temperature (161° to 814°C) and at one temperature (735°C) over a range of total pressure from 4.8 mm to 18.5 mm. The combination was found to be complex, consisting of a second‐order homogeneous reaction and a first‐order, presumably heterogeneous reaction. Only the second‐order reaction was studied in any detail. The rate constant or collision efficiency of this reaction was found to increase with decreasing temperature but showed no dependence on the carrier gas pressure. A negative temperature coefficient was found for the combination which, if expressed as an activation energy, was −2.2±0.5 kcal. It seems, however, more reasonable to regard this effect as a change in the effective collision diameter of the methyl radicals with temperature, the change being due to the van der Waals energy of attraction between the radicals.


Growing seed for profit is a possibility for private growers, and although returns can be good, it is a high risk venture. Growers are advised to partner with organisations that have specialised expertise, especially for the more complex seed orchards, but there are probably some good opportunities for seed production areas in the revegetation and direct seeding markets. The other benefits that come from having the trees are an important reason why many small growers establish stands for seed production.


As a thinker and a founder of the history of art in modern Japan,OKAKURA Tenshin( 1863—1913) traveled to China four times in his life and wrote a lot about China. In his unique and pioneering theory of the differences and similarities between northern and southern China,he compared China with Europe and considered that China is the integration of diverse political groups. Even today,his particular analyses of the diversity of China's geography and space will provide many important clues for us to rethink the historical and culture momentum that has molded "China".


The tools of molecular biology have rapidly expanded our knowledge of how β-cells regulate insulin gene expression. As this work has progressed in parallel in different laboratories, alternate nomenclature systems have been developed to describe the functionally important elements of the insulin gene. This jumble of names is confusing to those outside the field and intimidating to neophytes. Therefore, we have agreed to a simple, uniform set of names for the major insulin gene promoter elements.

It was found immunologically that the anti-SGP reacting protein, the designation for the whey protein which reacted with the antiserum to the soluble glycoprotein (SGP) isolated from bovine milk fat globule membrane, was mostly concentrated in the component-3 fraction of the proteose-peptone. Chemical characteristics such as amino acid and carbohydrate compositions of the component-3 fraction were markedly different from those of SGP. Disc electrophoretic properties were also dissimilar to each other. However, when the component-3 fraction was dissociated with sodium dodecyl sulfate (SDS) and its polypeptides were analyzed by SDS-polyacrylamide gel electrophoresis, a common glycopeptide having similar mobility was found in both the component-3 fraction and SGP. The results suggest that this common polypeptide has identical antigeneicity to both materials.

HS is a talented young footballer from one of the Gulf States who was used to playing football barefoot. As he progressed in the game and came into contention for membership of his country's National Squad difficulties were experienced because he had a supernumerary toe and was unable to get his foot into football boots. He therefore could not play in international or league games when other players were wearing boots.


Quantum field theory predicts that vacuum energy (or what is the same, cosmological constant) should be 50-100 orders of magnitude larger than the existing astronomical limit. A very brief review of possible solutions of this problem is presented. A mechanism of adjustment of vacuum energy down to (almost) zero by the back-reaction of massless vector or second rank tensor fields is discussed.


The composition and antimicrobial activity of the essential oil of Thymus daenensis Wild, an endemic species from Iran, was studied. The volatile oil obtained by hydrodistillation was characterized by the physico-chemical properties, gas chromatography (GC) and gas chromatography/mass spectrometry (GC/MS) techniques. Thirty compounds, accounting for 97.5% of the total oil, were identified. The main constituents were thymol (29.8%) and carvacrol (13.6%), p-cymene (11.3), borneol (6.8%) and 1, 8cineole (5.89%). The antimicrobial activity of essential oil of T. daenensis was tested against two Gramnegative and Gram-positive bacteria and three fungi by disc diffusion method. The results of the bioassays showed the interesting antimicrobial activity, in which the Gram-positive bacteria, Staphylococcus aureus, was the most sensitive to the oil, as well the oil exhibited a remarkable antifungal activity against all the tested fungi. These results confirm the possibility of using T. daenensis in food system, medicine and pharmacy.

In order to explore ways of strengthening clinical nursing through an organic combination of holistic nursing and humanitarian nursing,the basic concept of the holistic nursing was expounded. It was proposed that to combine the holistic nursing and humanitarian nursing was necessary by establishing new medical concepts,understanding medicine and society comprehensively,cultivating moral sentiments and human science ability,and regulating ethical behavior. The organic combination enhanced the quality of the nursing staff,standardizes the nursing behavior,and improved the quality of nursing by achieving the "three transformation" and,"six standardizations" ,which enhanced the quality of the nursing staff,standardized the nursing behavior,and improved the quality of nursing.


The invention discloses a deodorization method of tuna muscle and a special reagent thereof. The deodorization is realized by taking 0.3-0.75 part of NaCl, 2-10 parts of table vinegar, 4-10 parts of green agent and 200-300 parts of water as deodorization agents according to mass fraction. Under the condition of an optimized design, the optimal deodorization method is obtained by combining the tea and the water with the table vinegar to deodorize, and taking salt as a synergistic stabilizing agent. The nutritional ingredients of a fish product which is deodorized are not changed, the quality of the fish product is largely improved, and the overall development of aqueous products such as fish can be effectively promoted.

Blind and visually impaired persons face many challenges due to isolation, the most important is lacking education due to social immobility. Yet, since the development of the well-known white-red cane, only few advances have been made to increase the mobility of blind people. GPS systems are often used for pedestrian navigation but lack precision, foremost in rural areas where navigation is most often needed. The aim of the IMAGO project is therefore the development of an inexpensive and unobtrusive navigation method for blind and visually impaired persons. Navigation is performed using structure from motion and image-based localization techniques. Route models are created as 3D point clouds through several steps: (i) image acquisition along the routes; (ii) bulk-transfer of images to a server; (iii) feature extraction; (iv) feature matching between images; (v) creation of 3D point cloud with structure from motion. Similarly, the navigation chains seven steps: (a) image acquisition while walking a route; (b) immediate transfer of image to a server; (c) feature extraction; (d) feature matching between image and 3D route model; (e) localization/camera matrix calculation; (f) navigation/calculation of direction based on localization; (g) transfer of direction to user. Current smartphones are used as devices both for recording of routes as well as navigation. Thereby, a high level of dissemination without additional costs is possible, both, within blind people for navigation, as well as seeing people for route creation. Additionally, haptic feedback can be used via a smart cane to reduce auditive feedback. The proposed system yields a high positioning accuracy of 80% of samples being located within 1.6 m. Thus, the system is usable for pedestrian navigation, especially for visually impaired persons.


Community-based theatre is not only an integral part of contemporary theatre. This specific theatrical movement belongs to the wider field of such art practices, in which the participation of the community and community involvement into artistic process is considered to be the most important creative condition. Community-based theatre is an effective means for communities to share collective stories, get involved into social and political dialogue and break down the exclusion of marginalized groups. In recent decades, community-based theatre became such a widespread field that it encourages theatre researchers to rethink traditional criteria of performance analysis and to search for new analytical tools suitable for the analysis and interpretation of this phenomenon. This article aims to discuss the phenomenon of community-based theatre and to present such participatory and collaborative creative strategies which help artists create collective theatre narratives expressing problems, interests and beliefs of certain communities. Community-based theatre projects are not widespread in Lithuanian art context. However, there are some creative projects which promote community involvement, participation and collaboration between artists and community members to some extent. The article refers to theoretical issues of community-based theatre and focuses on two case studies: the production "Pro Memoria Sv. Stepono 7" ("Pro Memoria Saint Stephen's Street, Number 7"; theatre company Miraklis, directed by Vega Vaiciūnaitė in 1995 in collaboration with multicultural community of one quarter of Vilnius old town) and the performances by Kaunas dance theatre Aura "Tylus ėjimas" ("Silent walk", 1999) created in collaboration with elders, "Kelias" ("Road", 2001) created in collaboration with disabled, "re-gi-ne-re-gi" ("seedo-not-see", 2002) created in collaboration with blind people.


SUMMARY In this paper, we summarize the different formula proposed by different Spanish authors, and we try also to investigate which one were used to evaluate the magnitude of the events included in the regional and national Spanish Catalogue and Bulletins, since the first reliable instrumental data to day . The task is not easy, because in some cases we can't find complete information about how they were obtained. Besides, we compare the different formulas.


Treatment practices vary widely across hospitals, often with little connection to patients' medical needs. We assess impacts of these differences in delivery practices at childbirth. We find that infants quasi-randomly delivered at hospitals with higher C-section rates are born in better shape and are less likely to be readmitted, with suggestive evidence of improved survival. These benefits are driven by avoidance of prolonged labors that pose risks to infant health. In contrast, these infants are more likely to visit the emergency department for respiratory-related problems, consistent with a large observational literature linking C-section to chronic reductions in respiratory health.

This paper considers bidding automata programmed by experienced subjects in
sequential first price sealed bid auction experiments. These automata play against
each other in computer tournaments. The risk neutral subgame perfect Nash equilibrium
strategy of the independent private value model serves as a benchmark. The
equilibrium strategy does not describe any of the heterogeneous automata programs
submitted by subjects and does not always perform better than average in the tournament.


This paper describes a micro-optical three-axis tactile sensor capable of sensing not only normal force, but also shearing force. The normal force was detected from the integrated gray-scale values of bright pixels emitted from the contact area of conical feelers. The conical feelers were formed on a rubber sheet surface that maintains contact with an optical waveguide plate. The shearing force was detected from horizontal displacement of the conical feeler. In the experiments, a precise multi-axial loading machine was developed to measure sensing characteristics of the present sensor. Results show that the normal force was specified uniquely under combined force conditions and that the shearing force was specified by modifying the relationship between the shearing force and the horizontal displacement on the basis of normal force. We formulated a set of expressions to derive the normal force and the shearing force by taking into account this modification. Furthermore, calibration coefficients were identified for transforming the integration of gray-scale values into the normal force and for transforming the horizontal displacement into the shearing force. This result suggests that the expressions can estimate the normal force and the shearing force in wide-load regions.


Di8cussion.-Mr. R. C. ELMSLIE said that he had seen a c_ge-in a boy-in which a skiagram showed bone of a consistency similar to that in Mr. Brockman's case, the bones involved being the lower end of the fibula, the os calcis, and the outer two metatarsal bones. He regarded it as some form of architectural peculiarity in bone, such as occurred every now and again, and was associated with some defective growth. In his own case there had been such defective growth, leading to a bad valgus deformity. He believed the condition had not yet been recognized as an entity, but this might follow if several cases were carefully described.

Spermatogenesis is a complex differentiation process which is characterised, among other features, by conspicuous stage-specific nuclear events such as the pairing of homologous chromosomes coupled with the formation of synaptonemal complexes, the replacement of histones with sperm-specific proteins during spermiogenesis and, as a result, chromatin condensation and its inactivation in sperm cells. The chromatin of spermatogenic cells undergoes dramatic conformational changes upon differentiation from spermatogonia to mature spermatozoa. During the haploid stage of spermatogenesis, histones are gradually replaced, firstly by transition proteins and later by sperm-specific proteins. As a result of the high degree of condensation and inactivation of spermatid and sperm chromatin, Sertoli cells are responsible for the nourishment of germ cells with ribosomal RNA and nutritive substances.


Cu would be doped and form deep level centers easily in CdTe solar cells. The deep level centers in ZnTe back contact and graphite back contact CdTe solar cells were studied by deep level transient spectroscopy(DLTS). The electronic density of states on zinc blende CdTe, V Cd system and CdTe doping Cu were analyzed with density functional theory. The d-orbital splitting of Cu 2+ in C 3 v and T d fields was obtained. The results show that two deep centers E v +0206 eV and E v +0122 eV,respectively,are attributed to substitutional Cu,energy of CdTe is reduced after Cu doping,and Cu could replace Cd.


Simultaneous localization and mapping (SLAM) of unmanned systems has been proposed in last decade for global navigation satellite systems (GNSS) denied environments. In this reseach it is identified in details by detecting SLAM algorithms particularly in air vehicle platforms as a tool for application of an automation strategies from other domains to air transportation or surveillance and navigation applications of data science in aviation besides particle and particle flow filter based SLAM of aerial systems is first stated as well. Regarding to survey consequences the variety of SLAM applications span from parametric filters such as Unscented Kalman Filter, Extended Kalman Filter to nonparametric such as Particle Filter and concerning diversity of vision based approaches that aims up level control and variety of sensors that unmanned vehicles carry a taxonomy is a requirement of better comprehension SLAM performances. Although it is not aimed to compare performance of all SLAM methods for problem of Airborne-SLAM (A-SLAM) navigation the scan of indexed papers suggests that best SLAM algorithm can only be identified in reference to the scenario which differs in environment, platform, vehicle, sensor...etc. and can be used as an transportation tool by combining path planning and other navigation approaches.

Detailed evaluation of a proposed Engineering Change (EC) or its effects is a time-consuming process requiring considerable user expertise. Therefore, enterprises plan detailed evaluation of only those EC effects that might have a significant impact. Since similar ECs are likely to have similar effects and impacts, past EC knowledge can be utilized for determining whether the proposed EC effect has significant impact. Utilizing past ECs to predict the impact of proposed EC effect requires an approach for computing similarity between ECs. This paper presents an approach to compute similarity between ECs that are defined by a set of disparate attributes. Since the available information is probabilistic, the fundamental measures of information are utilized for defining measures to compute similarity between two attribute values or ECs. The semantics associated with attribute values are identified and utilized to compute similarity between attribute values. The similarities between attribute values are aggregated to compute the similarity between ECs in the context of overall goal. A case-study is presented to demonstrate the applicability of the proposed approach.


This study presents a new concept for full-capacity wind turbines (WTs) to emulate inertial response behaviour by optimising phase-locked loop (OPLL). The proposed OPLL-based concept can make full-capacity WT spontaneously respond to frequency events in grid with no more need for frequency measurement and calculations of its variation or differential, which are usually required to calculate the desired extra support power or chosen to trigger a predetermined active power shape etc., in common methods. Comprehensive analysis and comparisons are presented for full-capacity WT with two different generic control structures by establishing corresponding motion equations with regard to the active current dynamics. The established motion equations theoretically indicate that PLL dynamics and the related active power controls are in the equally important positions and greatly influence the frequency response behaviours of full-capacity WT, which constitutes the theoretical basis of the proposed OPLL-based methodologies. Simulated results demonstrate the feasibility and correctness of the OPLL-based methodologies. The influences of key parameters concerned corresponding to each proposed OPLL-based methodology are studied. Finally, the proposed methodologies for two generic control structures are also briefly compared and evaluated.


We provide additional natural image fitting results in Figs. 8 and 9. We also include the case of training "unfair" vanilla BACON in a staged fashion which, unlike the proposed fair variant, does not continue to update the linear output layer during the subsequent optimization stages of each scale. For the generalization task, we visualize the final reconstructions of SAPE [9], BACON [8], and our proposed method and compare it with ground truth as in Fig. 10


The impact of drainage water pollution on the genetic material of bioindicator Allium cepa L. was assessed by cytogenetic analysis. Allium cepa L. was germinated in three samples of drainage water in addition to the Nile water as a control. Waste water used in this study included agriculture drainage water and liquid industrial wastes resulted from chemical fertilizer industry. This study aimed to investigate the cytological effects of drainage water from different resources on root meristems cells of Allium cepa L. Exposure of onion roots to the waste water showed chromosomal abnormalities which was pollution–dependent. Drainage water induced a variety of chromosomal abnormalities which gradually increased in Kfr El – Sheikh drainage water, Menyet El – Nasr drainage water and industrial waste water, respectively. The drainage water discharged in Menyet El – Nasr center and that discharged from chemical fertilizer industry was effective in forming micronuclei, binucleated cell and disturbance of the spindle fibre apparatus due to high concentrations of chemicals present in these drainage wastes. The toxic chemicals present in drainage water were responsible for the observed genotoxic effects. Laggards, sticky chromosomes, anaphase bridge and fragmented chromosomes being the most frequently seen in all treatments with drainage water. Treatment with drainage water decreased mitotic index and increased the frequency of chromosomal abnormalities compared with the control. To conclude, the untreated drainage water mostly contain toxic chemicals leading to mutagenicity. Based on these findings, the bio monitoring investigation and treatment of drainage water before discharging into the environment are needed. Therefore, mutagenicity/ genotoxicity assays must be considered in water quality monitoring programs to avoid the mutagenic hazards of waste waters.


The dry development of sub‐0.25 μm silylated resist features patterned at 193 nm was optimized in an oxygen plasma using a high‐ion‐density plasma etcher. Low pressure and low wafer temperature eliminate lateral resist loss, resulting in vertical profiles, linewidth fidelity, and large process latitudes for 0.175 μm silylated resist features.


A series of novel 8-OMe ciprofloxacin (CPFX)-hydrazone/azole hybrids were designed, synthesized, and evaluated for their in vitro biological activities. Our results reveal that all of the hydrozone-containing hybrids (except for 7) show potency against Mycobacterium tuberculosis (MTB) H37Rv (minimum inhibitory concentration (MIC): <0.5 μM), which is better than the parent drug CPFX, and comparable to moxifloxacin and isoniazid, some of the tested Gram-positive strains (MIC: 0.06–4 μg/mL), and most Gram-negative strains (MIC: ≤0.03–4 μg/mL).


[Objectives]To study the change of radiation dose rate after taking different doses of 131I among patients with thyroid cancer and its significance.[Methods]The radiation dose rate of 32 patients with thyroid cancer who were given 131I with doses of 3.7~7.4 Bq(100~200 mCi)was measured at distance of 1m and 2m in different time for six days in a row.[Results]The radiation dose rates of different dose all reached the peak after taking 131I 1 hour,and descended subsequently,the descending speed increased with dose.The radiation dose rate at distance of 2 m was lower than that at distance of 1 m significantly(P0.01),and the descending curves were similar.There was no significant difference in radiation dose rate between at distance of 1 m on 6th day,at distance of 2 m on 5th day and background before treatment.[Conclusion]After taking different dose of 131I,the increasing and descending of the radiation dose rate among patients with thyroid cancer were related to dose obviously.The radiation dose rate decreased with time,and there was no difference between that on 5th and 6th day after treatment and background before treatment.


Accept Date 2020-04-03 ABSTRACT Background: This study assessed the awareness of occupational lead exposure risks, self-reported lead poisoning symptoms and work practices and using personal protective equipment among petrol station workers in Sana'a city, Yemen. Subjects and methods: A cross-sectional study was conducted among 172 petrol station workers in nine districts of Sana'a between January and May 2017. Data about demographic characteristics, awareness of the lead exposure risks, selfreported lead poisoning symptoms and work practices and use of personal protective equipment were collected. Inclusion criteria were workers who gave informed consent to participate, were aged 18-60 years and had been working for ≥6 months. The data were then analyzed using appropriate statistical tests. Results: The majority of workers were aware of the adverse health effects of leaded petrol (61.0%) and that lead is an environmental pollutant (60.5%). However, personal protective equipment was poorly used. Workers with secondary education and above had better practices than those with primary education. Approximately 76.2% of workers had poor knowledge of lead risks, and 13.4% of them had good practices. The most common self-reported symptoms were neurological, including fatigue (68.0%), concentration difficulties (61.6%), joint pain (58.1%) and headache (55.2%). Conclusions: Petrol station workers in Sana'a realize the exposure to lead risks because leaded petrol is the fuel type used in the country. Although the majority of workers perceived such adverse health effects, use of personal protective equipment was poor among most of them. The level of workers' education seems to influence their practices of using personal protective equipment.


Objective:  Approximately 50% of patients with depression report symptoms of pain, yet the clinical and biological mechanisms underlying this association remain unclear. Recent neuroimaging studies, however, support the contention that depression, as well as pain distress and rejection distress, share the same neurobiological circuits. In this study, we aimed to examine the hypothesis that perception of increased pain during depression is related to increased rejection sensitivity.


Idiopathic pulmonary hemosiderosis (IPH) usually presents with hemoptysis and iron deficiency anemia. In this report, an unusual presentation of IPH is described. 11-year-old boy presented with clinical features suggestive of hemolytic anemia. However, on detailed evaluation, he was diagnosed to have IPH and confirmed by the presence of hemosiderinladen macrophages in bronchoalveolar lavage fluid (BALF). The child was managed with oral corticosteroids, and he was doing well on follow-up.


In the supply-chain literature, an increasing body of work studies how suppliers can use incentive schemes such as quantity discounts to influence buyers' ordering behaviour, thus reducing the supplier's (and the total supply chain's) costs. Various functional forms for such incentive schemes have been proposed, but a critical assumption always made is that the supplier has full information about the buyer's cost structure. We derive the optimal quantity discount policy under asymmetric information and compare it to the situation where the supplier has full information.


On 6 January 2021, an angry mob of supporters of outgoing President Donald Trump stormed the Capitol building. Their intention was to 'stop the steal', preventing the nation's elected representatives from ratifying the votes of the Electoral College removing Trump from office. They had been egged on by the President, who promised falsely that he would join them in a march down Pennsylvania Avenue to undertake the action. Trump used stark quasi-Nietzschean or fascoid language, exhorting the crowds that only 'strength', not 'weakness', would allow them to keep their country. Longtime Trump ally and lawyer Rudy Giuliani called for a 'trial by combat' to overturn the electoral vote, which Trump and friends had been claiming for months – starting well before the election – had been 'rigged'. The spectacle of a ragtag collection of overwhelmingly white protesters storming the US Capitol, scaling the sides of ornamental stairs, smashing windows, spraying and being sprayed by tear-gas, and then occupying the offices and even the Senate Chamber itself was undoubtedly shocking. For many, it represented something impossible in the land of 1776, George Washington and Abraham Lincoln, the country whose intervention in the European theatre in the Second World War had all-but-ensured the final defeat of European fascism in 1945. For scholars of the Far Right, however, the events of 6 January will have been experienced differently. Unlike President-Elect Biden, who echoed the shock that 'this could ever happen here', many of these scholars were surprised only that it had taken so long. This, given the rise of the online Alt-Right preceding and surrounding Trump's election in 2016, and the growing number of citizen


The purpose of this study was to determine the degree to which Kouzes and Posner's Transformational Leadership Model is being practiced by school principals as perceived by their teachers in Jordanian schools. Means, standard deviations, t-tests, and one-way analysis of variance (ANOVA) were utilized in this study. Results indicated that transformational leadership is being moderately practiced and applied by Jordanian principals. Furthermore, statistical results indicated that gender and school type had an influence on teachers' perceptions in favor of female teachers and basic schools respectively. Finally, there were no significant differences among the three experience level groups of teachers (new hiring, middle career, and long experience) in their perceptions of each dimension of Kouzes and Posner's model.


Program PF provides a method for a 7600 user to copy his disk files to magnetic tape(s). When at a later time the user wishes to attach a disk file which has been purged, program PF will retrieve the file from an archive tape and catalog it on disk. A disk file called ARCHIVEDIRECTORY, which contains information about each file, is maintained by PF. The program CNDENSE, which purges specified files from user archive tapes and consolidates the remaining ones, is also briefly described. (RWR)


Given the non-existence of a standard quality index for ornamental slate, granite and marble blocks, classical classification methods such as Bieniawski's rock mass rating (RMR) and Barton's Q System are typically used, very much unquestioningly and indiscriminately. These methods, however, were originally designed for a different purpose, namely to identify and solve stability problems in underground excavations. Furthermore, they rely on pre-established parametric formulas that do not necessarily coincide in terms of criteria with rock quality experts. In fact, the fit between both perspectives has never been properly evaluated. In this article, we propose a quality index for ornamental rock constructed using machine learning techniques (support vector machines (SVMs)) to model the quality grade allocation procedure as applied by the expert. This quality index is composed of a set of logical rules consisting of mathematical inequalities in relevant ornamental quality variables. Nonetheless, the fact that the SVMs have the drawback of being difficult to interpret complicates the process of extracting the quality rules used by an expert. To overcome this drawback, we used classification and regression trees (CARTs) trained using SVM output.


Improving catalytic activity and durability are two major issues that must be addressed for fuel cells to become commercially viable. Surface modifications and doping of the catalyst support has been shown to effectively address both of these issues through significant improvements in the catalyst-support interactions [1, 2]. In this work we discuss the role of nitrogen doping via ion-implantation on the stability of a Pt-Ru nanoparticle catalyst phase supported on model highly-oriented pyrolytic graphite (HOPG) substrates.

Due to their unique combination of features such as large deformation, high compliance, lightweight, energy efficiency, and scalability, dielectric elastomer (DE) transducers appear as highly promising for many application fields, such as soft robotics, wearables, as well as micro electro-mechanical systems (MEMS). To generate a stroke, a membrane DE actuator (DEA) must be coupled with a mechanical biasing system. It is well known that nonlinear elements, such as negative-rate biasing springs (NBS), permit a remarkable increase in the DEA stroke in comparison to standard linear springs. Common types of NBS, however, are generally manufactured with rigid components (e.g., steel beams, permanent magnets), thus they appear as unsuitable for the development of compliant actuators for soft robots and wearables. At the same time, rigid NBSs are hard to miniaturize and integrate in DE-based MEMS devices. This work presents a novel type of soft DEA system, in which a large stroke is obtained by using a fully polymeric dome as the NBS element. More specifically, in this paper we propose a model-based design procedure for high-performance DEAs, in which the stroke is maximized by properly optimizing the geometry of the biasing dome. First, a finite element model of the biasing system is introduced, describing how the geometric parameters of the dome affect its mechanical response. After conducting experimental calibration and validation, the model is used to develop a numerical design algorithm which finds the optimal dome geometry for a given DE membrane characteristics. Based on the optimized dome design, a soft DEA prototype is finally assembled and experimentally tested.


The micropositioning problem of a flexible link manipulator system is considered in this dissertation. The flexible link is coupled to a dc-motor whose friction is compensated by a neural network controller. The controller's output resembles that of a Pulse Width Modulated controller, and a fuzzy logic scheme is employed to reduce the amplitude and the repetitions of the control switchings. Having compensated the motor dynamics, an adaptive supervisory robust controller is used to control the underlying dynamics of the flexible-link robotic system. This supervisory controller is based on the internal model control principle and attempts to progressively increase the bandwidth of the closed-loop system. Experimental and simulation studies on friction identification, compensation, and control of a single flexible link manipulator are offered to support the effectiveness of proposed control designs.


The objectives of this study were to inventory of plant species, determine rank taxonomy of species, and to give informationquantitative value of taxa for vegetation analysis. About 5 hectare of the Tahura region is belong to Inhutani IV Company, was chosen as research population of this study. Two and half of hectare (2,5 ha) of this region used as a observed area. The data was collected by transec and quadratic method. The observed area it was took 10 transec with 250 m of long for observed stations. Each observed station was put six quadratic sampels systematically. Each quadratic sampels has a 2,5 m2 of width. The parameter search is the total species. The result of this study indicated that there were 66 species of the plant including 29 family. Diversity index was between 2.3896-3.4696, an evenness index was between 1.7331 unto 211.5479. Based on this data, it can be conducted that every family of the plant has a few species. The important value is relatively low on all stations observed. So that there is no evident showing, any dominant species of the plant in observed area. Diversity index was categorized medium (> 2 - 4). Diversity index can be used as indicator were the vegetation succession. Evenness index of each station was relatively low, because sum of species were varied. Similarity index was below 50%. The differences might be the results of several factors including variety of physical environment, chemical content of soil, and interaction inter species in observed area.© 2003 Jurusan Biologi FMIPA UNS SurakartaKey words: vegetation, diversity index, Tahura Seulawah


Objective To study the regional cerebral blood flow (rCBF) in important brain functional areas and the metabolic levels of these brain functional areas in patients with primary hypothyroidism by using arterial spin labeling (ASL) and magnetic resonance spectroscopy (MRS) techniques to explain the possible causes of brain dysfunction in patients with primary hypothyroidism. Methods Twenty-five patients with primary hypothyroidism (newly diagnosed and not treated) who were treated in the endocrinology department of our hospital were selected as the research group, and 25 healthy patients with normal thyroid function who came to our hospital during the same period with matched gender and age were selected as the control group. ASL and MRS techniques were used to detect and calculate regional cerebral blood flow (rCBF) in the frontal lobe, hippocampus, and posterior cingulate gyrus, as well as N-acetylaspartate/creatine (NAA/Cr), choline/creatine (Cho) in the brain/Cr, and inositol/creatine (mI/Cr) ratio. The correlations between metabolite ratios measured by rCBF, MRS, and serum TSH, FT3, and FT4 levels were analyzed. Results Compared with the control group, the rCBF in the frontal lobe, hippocampus, and posterior cingulate gyrus of the dominant hemisphere of the hypothyroid patients in the study group decreased significantly (P < 0.05). The comparison of metabolite ratios showed that compared with the control group, the NAA/Cr ratio of the frontal lobe and posterior cingulate gyrus of the study group was significantly decreased, and the Cho/Cr ratio of the posterior cingulate gyrus of the study group was significantly increased. The MI/Cr ratio of the hippocampus was significantly decreased (all P values < 0.05). Correlation analysis showed that rCBF and NAA/Cr in posterior cingulate gyrus were significantly negatively correlated with serum TSH levels (P < 0.05). Conclusion The changes of rCBF and metabolite ratios in the frontal lobe, hippocampus, and posterior cingulate gyrus of patients with primary hypothyroidism can be detected using ASL and MRS techniques. The changes of rCBF and metabolite ratio and their negative correlation with serum TSH level are helpful to explain the causes of brain dysfunction in patients with primary hypothyroidism.

To the Editor.— The article by Stringfield et al (235:744, 1976) points out the difficulty of the differential diagnosis of pneumoperitoneum in a patient requiring ventilatory support and positive end-expiratory pressure (PEEP). All three cases demonstrated the pulmonary barotrauma (pneumothorax, pneumomediastinum, and subcutaneous emphysema) common after controlled ventilation with PEEP. Since pneumoperitoneum is also a sequela, its appearance soon after one of the aforementioned complications makes it extremely likely that it is a result of pulmonary barotrauma rather than ruptured viscus. We have seen this on three occasions recently in our own institution, all initially due to pulmonary causes. In addition, these problems are more likely with controlled ventilation than with intermittent mandatory ventilation (IMV). In fact, using the combination of low IMV rate or CPAP, our incidence of pulmonary barotrauma is no higher on PEEP greater than 20 mm Hg than when it is less than 20 mm Hg.


The purpose of this study was to examine the relationship between balancing ability during abrupt acceleration and the habitual physical activity level of elderly females. Thirty-one elderly females, aged 65-75 years, volunteered for this study. Changes in the center of foot pressure (CFP) were measured during postural sway following platform acceleration, and the response time and CFP displacement were evaluated. The scores of their daily physical activities (TS) -consisting of household activities (HS), leisure time activities (LS) and sports activities (SS)-were estimated by the modified Voorrips's questionaire method. Response time and CFP displacement correlated significantly with age (p<0.001). Response time also correlated significantly with the SS, LS and TS scores (p<0.05). CFP displacement also correlated significantly with the SS and TS scores (p<0.05). These results suggest that postural balancing ability during abrupt acceleration correlates significantly with the habitual physical activity levels, especially sports activities in elderly females.

We recommend using the West Cascades variant of the Forest Vegetation Simulator (WC-FVS) for developing yield tables for the current round of forest planning on the North Cascades unit. We recommend using the Flewelling taper system for estimating tree volume. Introduction Mason, Bruce and Girard, Inc., (MB&G) was hired by the Oregon Department of Forestry to help create yield tables for the current round of forest planning. The first task in the project was to evaluate and recommend a growth and yield model for this purpose. A related task was to recommend a tree volume estimation system to use for the project. In this particular report we present our recommendations for the North Cascades district. Background In previous reports and presentations to the ODF, we recommended using the Pacific Northwest Coast variant of the Forest Vegetation Simulator for developing yield tables for the current round of forest planning. That particular variant was recommended for both the Elliott State Forest and the northwest state forests (Tillamook, Forest Grove, and Astoria). The FVS-PN growth model was selected after comparing it with SPS, FPS, and Organon, and for the Elliott, RVMM. Comparisons considered the reasonableness of young stand projections, sensitivity to site index, the availability (or lack) of species-specific growth and mortality models, the ability to grow seedlings, the ability to represent the impact of disease (specifically, Swiss Needle Cast) on projections, the model's reliance on stand or tree age as a predictor variable, model documentation, user support, availability of the 1 Fairweather, S.E. 2003. Recommendation of Growth Model and Tree Volume Estimation System to the Elliott Core Team. 25 p. 2 "Growth Model Recommendation for the Northwest", PowerPoint presentation made 2/25/2004. ODF Yield Table Creation Project North Cascades Unit Model Recommendation June 1, 2005 4 20_Cascades_GrowthModel_Report.doc source code, and the ease with which the model could be incorporated into the current yield table generation system. Ultimately, the PN variant of FVS was chosen for each region. The recommendations were based on the model's excellent documentation, the availability of user support from the USFS (and from MB&G), reasonable projections for both young stands and older stands, the model's flexibility and adaptability, and fact that its projections are not agedependent. Coincident to MB&G's consideration of which growth model to use for the Elliott and Northwest forests, a report by Robinson and Monserud (2003) was published which considered criteria for growth model selection when the application of the model was going to be in populations or management scenarios for which none of the models might have originally been designed. The authors listed portability, extendibility, source code availability, and documentation as the important criteria, and in their look at Pacific Northwest individual-tree growth models, including CACTOS, FPS, FVS, ORGANON, and SPS, ultimately chose FVS. The PN variant of FVS has been working well in developing the yield curves for the Elliott and northwest forests. That experience, and the independent observations of Robinson and Monserud, suggest adopting the West Cascades variant of the FVS growth model (WC-FVS) for use in the North Cascades district. The remainder of this report describes our evaluation of the WC variant. The WC variant is described in detail by Donnelly and Johnson (1997). The applicable geographic extent for the model is shown in the accompanying figure from that publication. ODF Yield Table Creation Project North Cascades Unit Model Recommendation June 1, 2005 5 20_Cascades_GrowthModel_Report.doc Methods We asked the North Cascades district forestry staff to list a few typical stands from their inventory which we could grow in WC-FVS in order to evaluate the reasonableness of the model. Those stands are described in Table 1. The first three stands represent young, managed stands. The fourth stand (12662) is an older, natural stand. The vegetation label for stand 12126, 1D2H, is used for stands comprising approximately 25% of the acreage in the unit. Table 1. Example stands used to evaluate the WC-FVS growth model. We also asked for anecdotal data from the district to give us an idea of the range of observed basal areas and volumes at various stand ages. These observations came from the district's OSCUR inventory and cruise reports for timber sales, and are included in the Appendix. We grew each stand with the WC variant of FVS for 150 years, to check the reasonableness of the growth model. We knew from past experience with the PN variant of FVS that the default values for maximum SDI in the variant may be too high, so we also made projections using lower values for SDIMAX. The default value for all species 3 This is the site index at a base age of 50 years. The WC variant of FVS uses site index at a base age of 100.

The lnternct has become one of the most imporlant mediums of communication and information in modem society. For many, the rapid adoption of these technolo3ics in!o mainstream society has been combined with a reliance or> commercial software, most notably the Microsoft Corporation's Windows operating system. Question arise out of the c0mmercial dominance in a realm that until recently was characterised by the collective sharing of information and idet:~s. Although there is a lack of established sociological literature in this field, established literature on ownersf1ip, global capit<ll, politicul economy and social exclusion have been identified and drawn upon to fill this gap in research. The research process highlights both traditional theoretical concepts, mainly drawn from the work of Marx, and their implications in terms of the Internet, computers and other related


The fault detection time identified by relying on the over-voltage criterion of zero-sequence voltage often lags behind the actual occurrence time of ground faults, which may cause fault protection methods based on transient quantity principles to miss fault characteristics and lose their protection capability. To accurately estimate the time of occurrence of a single-phase-to-ground fault, this paper proposes a two-step dimensionality reduction algorithm for estimating the time of occurrence of a single-phase-to-ground fault in a distribution network. This algorithm constructs a filter based on Empirical Mode Decomposition (EMD) to establish a high-dimensional feature dataset based on the zero-sequence current of all feeders. After Principal Component Analysis and Hilbert Mapping Algorithm, the high-dimensional data are reduced to two dimensions to construct a two-dimensional feature dataset. The density-based clustering method is used to adaptively divide the data into two categories, fault data and non-fault data, so as to estimate the time of occurrence of the fault. The paper designs 11 sets of experiments including 7 common high-resistance grounding mediums to verify the accuracy of the fault time recognition of this algorithm. The accuracy of this algorithm is within 7.3 ms and it exhibits better detection performance compared to the threshold detection method.


PURPOSE: An optical amount controller of an optical device is provided to be capable of realizing an accurate brightness control by controlling the array angle of liquid crystal of an LCD panel using a digital signal, and to simplify the structure and save power consumption by simultaneously performing an iris function and an electron shutter function. CONSTITUTION: An LCD panel(100) comprises a first electrode for applying a common voltage, a second electrode for applying a first voltage, and liquid crystal between the first and second electrodes, and controls optical amount incident through the liquid crystal. Light passing through the LCD panel(100) is focused with a constant refraction rate by a lens part(200) A CCD part(300) converts an image focused by the lens part(200) into electrical signals. A control part(400) calculates an average brightness of incident light using signals output from the CCD part(300), and compares the average brightness with a preset brightness to output a control signal for performing an exposure correction process corresponding to the compared result. An exposure control part(500) outputs a digital signal for the first voltage corresponding to the control signal. A D/A converter(600) converts a digital signal output from the exposure control part(500) into the first analog voltage applied to the second electrode of the LCD panel.


This discussion of the use of a nasogastric tube covers the equipment needed, the method, rehydration and feeding, prolonged nasogastric feeding, and stopping nasogastric feeding. A nasogastric tube is useful when children are unable to drink safely and in sufficient amounts for any of the following reasons: severe dehydration; if intravenous (IV) therapy is unavailable; low birth weight infants; or the child is drowsy or vomiting. Severely malnourished children may be fed initially in this way if they are too weak or anorexic to eat or drink normally. The following equipment is needed: nasogastric tube; lubricating fluid; a syringe; blue litmus paper, if available; adhesive tape; stethoscope if available; and fluid to be given. Explain to the child's parents and the child, if old enough to understand, what will be done; lie infants flat; measure the approximate length from the child's nostril to the ear lobe and then to the top of the abdomen with the tube and mark the position; clean the nostrils to remove the mucus, and lubricate the tip of the tube and gently insert into the nostril; give the child a drink of water if he or she is conscious; continue to pass the tube down until the position marked reaches the nostril; use the syringe to suck up some fluid and test with blue litmus paper to check that the tube is in the stomach; and inject 5-10 ml of fluid (saline or oral rehydration solution, not milk formula) by syringe if satisfied the tube is in the correct position. Where possible, give a continuous drip of fluid. If this is not possible, give frequent small amounts using the syringe as a funnel. If feeding continues for more than 24 hours, clean the nostrils daily with warm water and change the tube to the other nostril every few days. Also keep the mouth very clean with a dilute solution of 8% sodium bicarbonate, if available, or citrus fruit juice. To remove the tube, remove the adhesive tape, take the tube out gently and smoothly, and offer the child a drink and gently cleanse the nostrils. After prolonged nasogastric feeding, a child may experience feeding problems or loss of appetite. Patient and encouragement are needed to establish feeding by mouth again.


The Hartree (mean-field) approximation to the description of the scattering of two heavy bound states is studied in a model consisting of bosons with attractive delta-function interactions. The approximation is derived from matrix elements of the Heisenberg equations of motion of the system and requires careful enumeration of all necessary approximations. The arguments made are verified by comparison of exact and approximate scattering amplitudes. The derivation also yields the physical significance of the amplitude which satisfies the Hartree approximation; it is a Fourier sum over amplitudes for different channels, which can in prinicple be recovered individually. The approach is not restricted to the model studied.


[Objective]To compare the effects between gasoline automobile exhaust gas and methanol automobile exhaust gas on the immune function of pulmonary macrophage,provide the basis for the selection of clean energy.[Methods]Based on the reaction that pulmonary macrophage receptor can present the rosettes combined with sensitized sheep erythrocytes with the different formation rate,the rabbit lung macrophages cultured for a certain period of time after lavage were exposed to gasoline and methanol exhaust gas extract according to the following concentration of 0.500 L / ml,0.250 L / ml,0.125 L / ml,0.062 L / ml and 0.031 L / ml,and were stored at 37 ℃ in 5% CO2 incubator for 3 hours.The sensitized sheep erythrocytes were added to the culture,placed in the refrigerator for 2 hours.The formation rate of rosettes was counted,and the antibody-dependent cell-mediated cytotoxicity test was conducted.[Results]Both gasoline and methanol exhaust gas can reduce the formation rate of macrophage rosettes,and the formation rate was 85.7% in non-exposure group.The formation rate of the gasoline group and methanol group in the minimum concentration of 0.031 L / ml was 47.0% and 70.0% respectively,which the formation rate of gasoline exhaust gas was significantly lower than that of methanol exhaust gas.The gasoline exhaust gas extract had obvious inhibitory effect on the antibody-dependent cell-mediated cytotoxicity,and the decrease range of this test by the gasoline exhaust gas was significantly larger than that by methanol exhaust gas.[Conclusion]The effect of methanol exhaust gas on the immune function of macrophages is significantly less than that of gasoline exhaust gas,so the methanol is more suitable for the clean energy.


Objective:To study the pathogenic role of pseudomonas aeruginosa(PA) in the pulmonary infection in aged patients. Methods: An experimental model of chronic lung infection caused by PA had been established in aged rabbits. Theses animals were divided into two groups, i.e. group A and group B. Group A inhaled saline suspension as the control and group B were challenged by PA suspension three times each week for four weeks. The body temperature and peripheral white blood cells(WBC) of these animals were measured, the bacteria in their bronchoalveolar lavage fluid(BALF) were incubated and the bacterial colonies were counted at the 3rd day, 15th, 30th and 60th day. At the same time, the pathological changes of the lung tissues were observed under microscope. Results: Compared with group A, the temperature and peripheral WBC and bacterial colonies in BALF were higher significantly in group B. In group B, severe hemorrhage and exudation, polymorphonuclears and macrophages infiltration were found, and many small abscesses could be seen under light microscope. Along with PA challenge continuing, the chronic lung pathological changes appeared gradually. Conclusion: The chronic lung infection model can be established by inhalation with PA suspension repeatedly in aged rabbits.


This paper examines the local government practice under the federal system of government in Nigeria. It highlights the performance of local government system in Nigeria as a federal entity. It accounts for the circumstances which underline the performance of the local government system in Nigeria and the impact on its efficiency and effectiveness. The secondary method of collecting data has been adopted in this paper and data collected were subjected to further documentary analysis. David Easton's systems theory is employed as the theoretical framework. The findings reveal that because the practice of federalism in Nigeria has failed to take into account the heterogeneous composition of its peoples, it adopted a uniform system of local government which has failed to make impact on the people within their localities. The paper recommends enthronement of genuine and practical democratic federal cultures across the country and a fundamental review of the laws that created the Nigerian local government system with a view to evolving fewer but stronger local governments that are relatively independent, functional and adapted to meet peculiar local needs.


Background: Clinical significance of J wave, one of early repolarization characteristics, in Brugada syndrome, remains to be elucidated. In this study, we examined the clinical significance of J wave in clinical symptoms and VF inducibility determined by electrophysiological study in patients with Brugada syndrome. Method and Results: We performed VF induction test in 30 consecutive patients who were suspected as Brugada syndrome with type 1 ECG appearance (male/female, 29/1; averaged age, 48±11 [SD] years old). Among the 30 patients, 24 were diagnosed as Brugada syndrome. In these 24 patients, 14 were symptomatic and the remaining 10 were asymptomatic. J wave was observed in 7 out of the 24 patients with Brugada syndrome (29% of Brugada syndrome). In contrast, none of the 6 patients with negative VF induction test had J wave. Moreover, among the 24 patients of Brugada syndrome, J wave was observed in only 1 case out of the asymptomatic 10 cases (10% of asymptomatic Brugada syndrome), whereas it was observed in 6 out of the 14 symptomatic patients (42% of symptomatic Brugada syndrome). Conclusions: These results indicate that J wave could have some clinical implications for both clinical symptoms and VF inducibility in patients with Brugada syndrome, suggesting that J wave reflects the arrhythmogenic substrates and the clinical phenotype in Brugada syndrome.

Classic game theory analyzes the interactions between individuals (Players) under assumptions of perfect rationality and homogeneity. Nevertheless, new theories have arisen; such as evolutionary game theory. The evolutionary game theory is not based upon assumptions of perfect rationality, but under processes of Darwinian natural selection. This work portrays the evolutionary process of neural networks (perceptron, a radial basis network) using genetic algorithms for the learning of decision making strategies in non-cooperative repetitive games, in which the parameters to set up the topology of the networks are obtained experimentally. Results obtained through the evolutionary process of neural networks are comparable to the ones obtained on literature using genetic algorithms and particle swarms for games such as: Prisoner's Dilemma, Chicken Games and Stag Hunt.

Subordinated debt is largely used by banks as a source of regulatory capital. However, due to new rules on «burden sharing» and «bail in», it has recently raised concerns in terms of consumer protection for retail investors. I provide some empirical data on subordinated bonds issued by European lenders, including securities addressed to small savers, and discuss how such bonds may be affected by new rules on recovery and resolution. I then turn to European regulations aimed at sheltering retail customers from mis-selling and mis-pricing, highlighting some possible weaknesses and discussing how they could be fixed by promoting better supervisory standards.
