Background and Objectives Insulin secretion entirely depends on Ca2+ influx and sequestration into endoplasmic reticulum (ER) of β-cells, performed by Sarco-ER Ca2+-ATPase 2b (SERCA2b). In diabetes, SERCA2b is decreased in the β-cells leading to impaired intracellular Ca2+ homeostasis and insulin secretion. Adipose mesenchymal stem cells (AMSCs) play a potential role in transplantation in animal models. The present study aimed at investigating and comparing the therapeutic effect of non-transfected AMSCs and SERCA2b gene transfected AMSCs on the pancreas of induced diabetes type 1 in rat. Methods and Results 58 adult male albino rats were divided into: Donor group: 22 rats, 2 for isolation, propagation and characterization of AMSCs and SERCA2b transfected AMSCs, in addition 20 for isolated islet calcium level assessment. Group I (Control Group): 6 rats, Group II (Diabetic Group): 10 rats, 50 mg streptozotocin (STZ) were injected intraperitoneal (IP), Group III (AMSCs Group): 10 rats, 1×106 AMSCs were injected intravenous and Group IV (SERCA2b transfected AMSCs Group): 10 rats, 1×106SERCA2b transfected AMSCs were injected as in group III. Groups I, II, III and IV were sacrified 3 weeks following confirmation of diabetes. Serological, histological, morphometric studies and quantitative polymerase chain reaction (qPCR) were performed. Nuclear, cytoplasmic degenerative and extensive fibrotic changes were detected in the islets of group II that regressed in groups III and IV. Isolated islet calcium, blood glucose, plasma insulin and qPCR were confirmative. Conclusions AMSCs and SERCA2b gene transfected AMSCs therapy proved definite therapeutic effect, more obvious in response to SERCA2b gene transfected AMSCs.


T present work aims to study the role of saffron in Ehrlich Ascites Carcinoma (EAC) in mice. Once the tumors were formed, the mice were divided into four groups (control, tumor, saffron and saffron & tumor). Each group contained eight mice. At the end of experimentation, the mice were dissected and a histological examination of both liver and kidney was performed on all groups. Also, the levels of alanine transaminase (ALT), aspartate transaminase (AST), urea, creatinine, malonyl dialdehyde (MDA), superoxide dismutase (SOD) and catalase (CAT) were measured in all tested groups. Saffron extract improved the histological structures of both liver and kidney bringing them close to normal structures. They also reduced the elevated values of ALT, AST, Urea, Creatinine, and MDA towards normal values in significant and non-significant changes, increased the reduced levels of SOD and CAT to near normal values and significantly reduced tumor volumes. Finally, saffron modulated the destructed genomic DNA to be in normal patterns.

Instructor is the main force to implement education policy,vocational quality education.Instructor's work is the key to setting up good school sprit,the guarantee of the improvement of student's quality.Therefore,strengthening the building of instructor team is an important part of the work of educating and managing students.After the uniting of colleges,some probes in assignment of instructor,education and management were made in the Department of Water Conservancy.


Inducing concept descriptions in first order logic is inherently a complex task; then, heuristics are needed to keep the problem to manageable size. In this paper we explore the effect of alternative search strategies, including the use of information gain and of a-priori knowledge, on the quality of the acquired relations, intended as the ability to reconstruct the rule used to generate the examples. To this aim, an artificial domain has been created, in which the experimental conditions can be kept under control, the "solution" of the learning problem is known and a perfect theory is available. Another investigated aspect is the impact of more complex description languages, such as, for instance, including numerical quantifiers. The results show that the information gain criterion is too greedy to be useful when the concepts have a complex internal structure; however, this drawback is more or less shared with any purely statistical evaluation criterion. The addition of parts of the available domain theory increases the obtained performance level. Similar results have been previously obtained on a number of real applications and of test-cases taken from standard machine learning data bases.


Timing data collection through memory compiler characterization is an integral part of memory compiler development. Simulations are run on an exhaustive instances list to cover the whole compiler range. Full characterization taxes resources immensely, both in terms of time and disk space. This paper focusses on on-the-fly donut creation methodology for the target memory compiler instance. In donut creation flow, nontiming critical bit cells are removed from the bit cell array while timing-critical bit cells are preserved. For an 80kB memory instance with close to 5 million transistors, RC extraction was not feasible using normal simulation machines. Comprehensive analysis, which earlier was impractical due to the difficulty of extracting the biggest (80kB) instance, was completed with the help of donut generation. Using on-the-fly donut formation flow, RC extracted net list was reduced by 75% and accuracy of timing simulations increased within 2%.


Forest carbon stocks—both in terms of the standing biomass and the soil organic carbon (OC)—were monitored in the mangrove plantation reforested from an abandoned shrimp pond for the 10 years following land excavation. Excavation to a level of 25 cm below the existing ground level increased the inundation time of tidal water from 463 to 7,597 hours per year, resulting in a significant increase of survival/growth rates for planted mangrove species, Rhizophora mucronata (RM) and Bruguiera cylindrica (BC), and of carbon stocks as well. RM showed high rates of standing biomass accumulation with 98.7 ton/ha while 28.8 ton/ha for BC was measured over 10 years in the excavated area. In contrast, the unexcavated area showed low rates of biomass accumulation, 1.04 ton/ha for RM and 0.53 ton/ha for BC in the same period. The excavated area recorded a twofold increase of soil OC in the upper 5 cm of the surface soil from 71.8 to 154.8 ton/ha in 10 years, however it decreased to 68.3 ton/ha in the unexcavated area where soil OC is susceptible to decomposition. These results imply that the potential of carbon sinks in reforested land from abandoned areas cannot be developed unless hydraulic conditions are properly recovered. The fast growing species Avicennia marina (AM) grew quickly for the first two years after colonization but its growth slowed down afterwards, showing a limited ability of carbon capture.


This article examines the ways in which depictions of race and racism in some prime-time historical dramas promote contemporary postracial ideologies. Focusing on the portrayals of overt racism and interracial relationships in Hell on Wheels (2011–2016) and The Knick (2014–2015), the author argues that the use of morally ambiguous white, male protagonists in contexts associated with morally unambiguous racism allows these shows to acknowledge the centrality of racism in American history while simultaneously presenting racism in interpersonal rather than systemic terms. This representational strategy differs from the politically correct depictions of race and racism in historical dramas like Mad Men (2007–2015). As such, Hell on Wheels and The Knick reflect the paradox of postracial popular culture whereby depictions of racial animus and violence support viewers' desires to forget about both race and racism. In contrast, the racial caste system in Deadwood (2004–2006) presents white supremacy and American history as inseparable. This article concludes by discussing some of the connections between these representational strategies and the shifting economic landscape of the post-network-era television. This article explores the relationship between moral ambiguity and postracial depictions of race and racism in several prime-time historical dramas. Specifically, this analysis argues that the juxtaposition of morally ambiguous, white, male protagonists with morally unambiguous, overtly racist white characters in Hell on Wheels (2011–2016) and The Knick (2014–2015) inscribes a contemporary postracial logic onto the American past. On one hand, the frequent use of racial epithets and graphic displays of racially motivated violence distinguish these shows from the long tradition of popular culture that denies the historical significance of race. On the other hand, positive interracial relationships between white protagonists and African-American characters allow viewers to historically situate racism as an individual-level phenomenon. As these depictions of race and racism create a veneer of historical authenticity, paradoxically, the power of such imagery is undone by narrative devices that deny any connection between the past and the contemporary realities of structural racism. This article begins with a discussion of postracial culture and a review of scholarship offering postracial readings of Mad Men (2007–2015). In contrast to representational strategies that rely on polite or politically correct depictions of racism, this article argues that Hell on Wheels uses its protagonist's identity as a former Confederate soldier and former slave owner to emphasise racial ambivalence and colour blindness as points of identification. This interpretation is then extended to the medical drama The Knick and its drug-addicted protagonist in New York City at the beginning of the twentieth century. If these depictions of race and racism can be understood as allowing white audiences to acknowledge the historicised existence of racial inequality while maintaining their ability to distance themselves from the systemic and historical perpetuation of racial inequality, then Deadwood (2004–2006) illustrates an alternative representational strategy. A brief consideration of this earlier show highlights the ways in which depictions of race and racism can complicate rather than simplify audiences' relationships to white protagonists in historical dramas. Considering these differing strategies, this article


In this paper,based on ANSYS7.0/LS-DYNA,an analysis is performed of the dynamic stress concentration at the edge of a hole(0.3 m×0.3 m) in a simplely-supported plate(3 m×3 m)subjected to triangularly-distributed explosive loads.The dynamic stress concentration factor is determined by using time-distributive function of energy density,and the emphasis is placed on discussing the effect of two parameters on the result :one is the time step used in the calculation and the other is the time intervel during which data are collected.


Sophie McCall. First Person Plural: Aboriginal Storytelling and the Ethics of Collaborative Authorship. Vancouver: UBC Press, 2011. 254 pp. Notes. Bibliography. Index. $32.95 sc. In the last few decades, there has been a growing dialogue about the appropriation of Indigenous "voice" in Canada and beyond. First Person Plural offers an important contribution to this discourse by examining collaborative work in various arenas: in literature and film, land claims, court cases, public inquiries, commissions, ethnographies and the making of history. How have Indigenous peoples been able to voice their truths and be heard? What has changed since Indigenous peoples began to challenge the colonial act of being spoken for? First Person Plural explores the successes and challenges of "multi-voiced" storytelling with Indigenous peoples. Literary scholar Sophie McCall invites us to consider moving beyond "parallel" voices where speaker and author represent binaries; to explore, rather, that in-between space where "voices-in-dialogue" can help to articulate evolving expressions of Indigenous sovereignty. McCall begins by connecting the call for Indigenous voice to the birth of modern Indigenous sovereignty in Canada in the early 1970s. She explores the efforts of Chief Justice Thomas Berger and anthropologist and filmmaker Hugh Brody to use Dene testimonial in work associated with the McKenzie Valley Pipeline hearings (1973-1975). McCall argues that these efforts were well intentioned and innovative at the time, but fell somewhat short of self-reflective analysis and translating Indigenous ways of knowing to the Canadian public. She then shifts to an examination of how Abenaki film-maker and Stodo writer Lee Maracle incorporated the multiple voices of Mohawk and other Indigenous people in storytelling about the resistance at "Oka" and, in Maracle's case, in telling Indigenous women's stories, including her own. In a later chapter, McCall examines how Inuit filmmakers use a multiplicity of Indigenous voices in their storytelling. She compares the collaborative and community based work on the film, Atanarjuat (2007) with the essentialist and static 1922 film, Nanook of the North, linking the timing and approaches of Atanarjuat to the birth of Nunavut (1999) as expressions of Inuit sovereignty. Other chapters invite us to consider the state's use of testimonial in comparison to how oral history is employed in exemplary Indigenous and non-Indigenous coauthored books. Chapter Four examines how the Royal Commission on Aboriginal Peoples (RCAP) missed the opportunity to "elicit the active participation of witnesses in the remaking of a shared history" (110). McCall contrasts this with the history presented in the 1997 book Night Spirits: The Story of the Relocation of the Sayisi Dene, co-authored by former Dene Chief Ila Bussidor and journalist Ustun Bilgen-Reinart and narrated by thirteen other Dene spokespeople. …


Appendicitis is one of the most common conditions encountered in emergency surgical practice. Fistulous communication of appendix into adjacent organs is rare. Appendicovaginal fistula is extremely rare.


It is possible to obtain a laminate having high adhesion strength between ceramic and a metal coating by providing the following: an insulating ceramic substrate (10); an intermediate layer (50) formed on the surface of the ceramic substrate (10) and having a metal-containing principal component metal layer (51) and an active ingredient layer (52) including metal, a metal oxide, or a metal hydride; and a metal coating (40) formed on the surface of the intermediate layer (50) by accelerating a metal-containing powder with gas, and depositing the same on the surface thereof by spraying while in a solid state.


Polyurethane (PU) coating degrades quickly under the irradiation of ultraviolet (UV). Thus, increasing the durability of the coating is necessary. In this study, porous CeO2-SiO2 nanocomposites (CS-NCs) were used to disperse into the PU matrix. The CS-NCs were prepared by a sol-gel combustion method using polyvinyl alcohol as precursors. Prepared nanocomposites were characterized by x-ray diffraction (XRD) analysis, Fourier transform infrared spectroscopy (FTIR), Scanning Electron Microscopy (SEM) as well as Energy dispersive x-ray (EDX) mapping analysis. Next, the prepared nanocomposites were employed for the preparation of PU coatings. The loading of nanoparticles was varied between 0.1% and 2.0%. These coating properties were investigated by using FTIR and UV–vis spectroscopy. As also in this study, these coatings were subjected to UV exposure with accelerated weather testing. The structural changes were characterized by applying FTIR analysis and measuring gloss and color deviation. The results indicate that incorporating nanocomposites into the polymer matrix improves the UV-durable properties of the PU matrix.


On Saturday, November 20, 2021, the Berklee Institute for Arts Education and Special Needs (BIAESN) hosted the first ABLE Conversation: Anti-Ableism, Representation, and Accessibility in Arts Education symposium. The event included keynote remarks from Rebecca Cokley and Gaelynn Lea, as well as discussions with attendees. Insights are shared from the event, focused on solidarity work; preparation, access, and opportunity; and the joy of disability culture. It concluded with a strong call to action for the arts education community to be revolutionary and throw out the playbook.


The concepts of Bayesian statistical decision theory have recently transformed research in perception by providing a rigorous mathematical framework for representing the statistical properties of the environment, for describing the tasks that perceivers perform, and for deriving computational theories of optimal performance on those tasks. Such computational theories (ideal observers) offer an appropriate benchmark for evaluating human performance, and, moreover, they can be modified to yield an excellent starting point for developing testable models. Unlike theories that focus on the role of invariant information for perceived events, the Bayesian approach treats information as probabilistic. The approach is illustrated for cases in which listeners learn to categorize artificial stimulus sets whose statistical properties (prior probabilities and stimulus likelihoods) are controlled by the experimenter. Prospects for extending the Bayesian framework to the analysis of speech perception are discussed in li...


virtue trembles, crushed within the arm which encircles the waist." Thompson points out that it "has also formed a basis for concert music and a vehicle for love songs" (57). In fact, one danza melody, "La borinqueña," became the anthem of the Commonwealth of Puerto Rico in 1952. In the aftermath of Spain's 1898 war with the United States, Puerto Rico came under the control of a new country and culture, an event that produced dramatic changes in its musical life. For one, the Americans had no intention of continuing European-style government subsidization of the arts. As a result, many institutions soon found themselves short of assistance. The era of the New Deal saw some improvement in this situation; moreover, the establishment of the Casals Festival in the 1950s attracted attention to the island and served as an enticement to industrial development and expanding tourism. Not everyone reacted with glee to this development, however. In 1972, years after its inception, Rafael Aponte-Ledée derided the Festival for "spreading a false image of Puerto Rico as a prosperous country, a model of progress and felicity thanks to its special condition as a protégé of the United States" (102–103). Thompson himself wrote an article on the subject in 1994 and took a much more benign view of the Festival, which he felt had invigorated the musical life and institutions of the island. Of course, classical music was not Puerto Rico's chief cultural export. The rise of urban and commercial music there, particularly the bomba, plena, and salsa, has transformed the way we view the country and its music. Many writers have focused on this phenomenon, in particular on the music of Rafael Hernández. Despite its obvious importance, the only study made to date of music criticism in Puerto Rico (and which is reprinted in this volume) is Sylvia Lamoutte de Iglesias's 1997 "La critica musical: origen y desarrollo," which contains an impassioned plea for a continuation of the tradition of musical criticism in the local press as a means of maintaining and expanding the musical public. By Thompson's own admission, his compendium of excerpts represents but a small fraction of what has been written about the musical life of Puerto Rico. Nonetheless, this book provides a necessary foundation and vital impetus for future investigations. Above and beyond that, it is simply a pleasurable and fascinating read.

Due to the increasing prevalence of local ordinances, sound energy radiated from transformers has become a factor of increasing importance to neighboring residential areas. It is therefore appropriate that a good understanding of sound power radiation and its measurement principles be developed for appropriately specifying sound levels in transformers. The authors argue that, in order to evaluate a sound source, one must understand the basic principles detailed in this paper and used for the quantification of sound energy.

Introduction: Recently, the risk of flood disasters due to concentrated heavy rains has been increasing in Japan. While some cases of hospital evacuation have been reported, standards for hospital evacuation have not been established and regional administrative evacuation plans do not include medical facilities. Aim: To clarify the timeline for in-hospital vertical evacuation during a flood disaster. Methods: A timeline was set for vertical evacuation as criteria of the hospital's emergency response based on the Arakawa River Downstream Timeline, which is an estimate of the time until river flooding based on the water level of the Arakawa River located near the facility. The timeline was calculated backward from 0 hours to when the river floods. A drill was held for verification. Results: The timeline was based on the water level of the Arakawa River and objective evidence of risky transfer of critical patients; therefore, the decision to evacuate was made when the water level reached a dangerous level (-3 hours). However, this did not provide enough time to evacuate patients in all hospital departments simultaneously, resulting in a shortage of human resources. There was a planned shutdown of the electronic clinical record system at 0 hours to avoid water damage and evacuation of its server, but three hours were not enough to prepare patient clinical summaries. Discussion: There is a need for greater and earlier preparation for evacuation to reduce or discharge patients who can leave the hospital when a flood disaster is predicted. Only in-hospital vertical evacuation was considered because it is very risky to transfer critical patients without an evacuation order from government or municipal officials. In fact, over 10,000 patients would need to be evacuated in the region if the Arakawa River floods. Therefore, a regional plan is indispensable for such large scale and simultaneous hospital evacuations.

Nonorthogonal multiple access technology has been proposed for use in 5G communications systems. In particular, the sparse code multiple access (SCMA) scheme is believed to be one of the most promising techniques among the various nonorthogonal approaches that have been investigated. In this letter, we focus on reducing the complexity of SCMA decoding and we propose a Monte Carlo Markov Chain (MCMC) based SCMA decoder. Benefiting from the linearly increasing complexity of the MCMC method, the proposed SCMA decoder has only 10% of the computational load compared to previous state-of-the-art methods when the codebook size is 64. Consequently, the MCMC SCMA decoder has great potential for use in practical system implementations.


THE notion that a characteristic price earnings multiple exists for each company is a frequent assumption of share-value analysis. Examination of the channel through which expected growth in earnings influences share value suggests, however, that a constant earnings multiple is warranted only in a very few, highly restrictive cases. The requisite conditions are plausible for certain firms whose earnings are small and growing at a nominal rate or for regulated firms that serve a constantly growing market, but they hardly characterize the vast number of firms whose earnings are large and exhibit occasional spurts of rapid growth. This article utilizes fundamental analysis to point out that, except in uncommon or artificial limiting cases, growth in share value does not equate to growth in earnings and price-earnings ratios should not be expected to remain constant over time.

CONSTITUTION: The positive red coloring photosensitive resin composition comprises 55-63 parts by weight of a dye; 10-30 parts by weight of a radiation-active compound; 10-25 parts by weight of a curing agent; a solvent; and optionally 1 parts by weight or less of an alkali-soluble resin based on the weight of solid part of the composition. Preferably the dye is a compound represented by D-(SO2NHR1)n or its salt, wherein D is a basic residue of a dye selected from the group consisting of a xanthene compound, an azo compound and an anthraquinone compound; n is an integer of 1-4; R1 is a C3-C20 aliphatic hydrocarbon group, a cyclohexyl group, a C1-C4 alkyl cyclohexyl group, a C3-C24 aliphatic alkoxyalkyl group substituted with a C1-C12 alkoxy group, a C3-C24 aliphatic ester group, or a C7-C20 arylalkyl group, preferably a C7-C20 arylalkyl group having an aryl group selected from phenyl and naphthyl groups capable of being substituted; and R1's are identical or different one another if n is an integer of 2-4.


An addition of cerium oxide to NiCrAiY coatings could boost the high temperature properties of the coatings in the actual service condition due to the purification of its microstructures. High temperature oxidation studies of D-Gun sprayed MCrAlY coatings with minor addition of CeO2 is inadequate in the literature. Therefore, the present work was focused to study the effect of cerium oxide on the high temperature oxidation behavior coatings on superalloys. Cyclic oxidation tests were carried out for 100 cycles at 900 °C to study the oxidation kinetics of un-coated and bare superalloys. The corroded products obtained during cyclic oxidation of coatings were subjected to XRD, FE-SEM/EDAX and X-ray mapping analysis to reveal the high temperature oxidation mechanisms.


A the heart of the old city of Warangal in southern India, which once served as the capital of the Kakatiya kingdom, there lies an open field strewn with five acres of broken architectural fragments: smashed columns, overturned slabs, and fractured beams (fig. 1). Truly, "a more vivid picture of willful destruction can hardly be imagined," as George Michell has observed, and it is perfectly fitting that a photograph of these ruins should grace the cover of the paperback Indian edition of Partha Chatterjee's The Nation and its Fragments (Michell, "City as Cosmogram"). My concern for the moment, however, is not with the metaphoric fragments of a nation, but rather, with the literal fragments of what was once a Hindu temple complex dedicated to the god Svayambhusiva. When standing, this temple would have been one among the marvels of medieval Deccani architecture. But, in the third decade of the fourteenth century, the temple was subjected to a thoroughgoing demolition when the Kakatiya capital was taken by the army of the Delhi Sultanate under the Tughluq prince Ulugh Khan. What is particularly enigmatic about this field of ruins is that it is bounded by four monumental stone portals, known as kirti-toranas, or "portals of glory," which were spared from the general destruction of the temple and still remain standing in almost pristine condition today (fig. 2).2 Towering over 30 feet high and 40 feet wide, these structures possess a monumentality that is only vaguely sensed through photographs. Why should these lofty portals have been spared, when everything else within the intervening space was razed? And even more puzzling, why is it that this unusual pattern of destruction and preservation has not even been commented upon by most scholars of Deccani art and architecture? Oddly, the problem remains ignored, and instead, Warangal's four kirti-toranas have simply been accepted as unproblematic vestiges of the Kakatiya past.3 Indeed, they have by now become emblematic icons of the Kakatiyas who built them, and by extension, of the Telugu Hindu identity that the Kakatiyas are often held to represent.


Blue-violet LEDs based on InGaN MQWs were grown by RF-plasma MBE on (0001) sapphire with GaN QDs incorporated in the nucleation layer as a mechanism of dislocation filtering. Devices with dimensions 800 μm x 800 μm were fabricated and evaluated at a bare die configuration by measuring their EL spectra and power output. At low injection current, the EL spectra peak at 440 nm. At high injection current a second peak at 385 nm becomes the dominant one and it is attributed to tunneling of injected electrons through the electron blocking layer. The dependence of the power output as a function of the injection current was studied systematically in order to evaluate the effects of heating. Power outputs up to 9 mW were measured at injection current of 1 A. (© 2008 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim)


Amyotrophic lateral sclerosis (ALS) is a rapidly progressive, degenerative disease of the voluntary motor system. Approximately 2% of cases arise in association with mutations in the gene encoding the protein Cu, Zn superoxide dismutase (SOD1). Transgenic mice that overexpress human SOD1 mutations develop a motor neuron disease resembling ALS. These mice provide a model to rapidly screen potential therapies for ALS. It was recently demonstrated, for example, that cerebroventricular administration of a different agent, zVAD-fmk, a caspase inhibitor, delays death in this model. We have used the ALS mice to test intracisternal delivery of bone morphogenetic protein-7 (BMP-7). BMP-7 stimulates the growth of spinal cord tissue, increases motor neuron size, and promotes the establishment of an extensive dendritic network in an intracellular transplantation model. In a rat model of stroke, 10 μg of BMP-7 administered intracisternally at either 1 and 3 or 3 and 5 days following focal cerebral infarction enhanced recovery of sensorimotor function. The half-life of BMP-7 is approximately 10–20 min in the cerebrospinal fluid but it can be observed throughout the CNS for at least 24 h after administration by intracisternal injection. When BMP-7 is labeled with either 125-I or 99-Tc, the protein distributes through the cranial vault and spinal column within a few minutes (Paul Kaplan, unpublished work). We tested the hypothesis that a single dose of BMP-7 at the time of disease onset might prolong survival in the G93A transgenic ALS mice. Forty-four ALS mice were divided into two equal treatment groups, BMP-7 and placebo. At the age of expected onset (80 days), the animals received a single intracisternal injection of BMP-7 or vehicle. The animals were anesthetized with a 1:1 xylazine/ ketamine mixture (0.01cc/kg). Using a Hamilton syringe (30 gauge), 10 μl of BMP-7 (10 μg) or vehicle was injected into the cisterna magna. The mice were monitored twice weekly after 60 days of age for disease onset and survival. Onset was determined as the first appearance of tremulousness in one limb, typically a hind limb, as detected by holding the mouse up briefly by the tail. After disease onset, study mice were observed daily to determine survival. Disease duration was defined as the age at death or euthanasia. Euthanasia was performed when a mouse was unable to roll over within 30 s after being placed on its back. Intracisternal injection of BMP-7 was safe; it produced no unusual behavior in the mice. There was no statistically significant difference in the mean survival time or the duration of disease between the BMP-7– and placebo-injected groups (Fig. 1). The mean disease onset for the placebotreated animals was 94.3 days (n = 22, sd 7.4) with a mean survival time of 134.4 days (n = 22, sd 7.4). For the BMP7–treated animals, the mean disease onset was 93.8 days (n = 22, sd 6.7) and the mean survival time was 135.9 days (n = 22, sd 12.1). It is conceivable that multiple injections or


Prime numbers are one of the most basic objects in mathematics and one of the most basic questions is to decide which numbers are prime (a clearly related problem is to find the prime factorisation of a number). Given a number n one would like a quick way to decide if n is prime, say using a computer. Quick can be given a precise meaning. First one measures the complexity by the number of digits, or what comes to the same thing d = ,log nl (we will work base 2, so that this is the same as the number of bits). The larger d the longer it will take to decide if n is prime, in general. We would like an algorithm that runs in polynomial time, that is, the algorithm is guaranteed to be over in a time given by a function that is polynomial in d; in essence we are looking for an upper bound for the running time of the form c · d, where c is some constant and m is an integer. This very famous problem was solved in 2002 by Manindra Agrawal, Neeraj Kayal and Nitin Saxena, the last two of whom were graduate students, in computer science from India The basis of their algorithm is the following simple idea. If n is a prime number then a n = a mod n, for every integer 1 ≤ a ≤ n − 1. This at least gives a way to test if a number is not prime.


The dynamics of the population resident in the Netherlands of Netherlands Antilles or Suriname origin are described for the period 1971-1986. This population represented about 1.6 percent of the total population of the Netherlands in 1986. Consideration is given to differences in fertility and mortality between this population and the Dutch population as a whole. (SUMMARY IN ENG)


By the fact of own spatial existence, the each object (process, phenomenon) forms a multilevel system, promoting differentiation and concentration. The necessity to study the territorial projection of international economic relations of various sizes is emphasized. The geography of foreign economic relations at three spatial levels is studied: 1) macrolevel (international trade), 2) mesolevel (foreign economic relations of Russia), 3) microlevel (foreign economic relations of the federal subject – the Republic of Bashkortostan). Combining these results allows us to establish interrelations, interdependencies between geographical levels that most fully reveal the basis of the functioning of the international division of labor. The application of territorial approach to studying foreign economic relations of countries and regions allows us to disclose the regularities of geographical division of labor, to reveal the cause-and-effect relationships of the functioning of international trade, the foreign trade of countries and individual administrative units of states, uniting them into a single system. Understanding the mechanisms of formation of this system gives rise to prospects to effectively manage it.


From December 2012 to May 2013, the Bureau of Labor Statistics (BLS) Producer Price Index (PPI) program conducted a user survey of its stakeholders in order to learn more about the program's data users and how they utilize PPI data. The survey was sent by email to more than 42,000 PPI contacts who had a preexisting relationship with the PPI, as either a survey respondent, a subscriber to a data product, or a user who had contacted the PPI program for technical information. To increase awareness, BLS highlighted the survey on the PPI website and announced it in the U.S. Federal Register. The survey resulted in a total of 3,790 responses.

Revising a misanalysis of a syntactic ambiguity elicits greater processing difficulty in some cases than in others. What factors contribute to processing difficulty at disambiguation when the dispreferred structure is required? Both serial and parallel syntactic processing theories have been proposed, which differ in how the parser responds to syntactic ambiguity. We define a serial parser as one that is committed to a single structure at each word position in an ambiguous sentence, even if multiple structural alternatives are considered initially. On the other hand, a parallel parser maintains multiple alternative structures of an ambiguity across several words.

The objective of this study was to observe the behavior of hypertensive patients along
with the factors affecting their self-care practice. The qualitative study was conducted during
the period July - December 2006 and involved 29 diagnosed hypertensive patients, the persons
who took care of them, the leaders of the health-care team in the community, and the healthcare staff of the local hypertensive clinic. Information was collected by personal interview,
group discussion, and observation. Data were analyzed and checked by using the content
analysis and triangulation techniques, respectively.
The results were as follows: most of the hypertensive patients pursued inappropriate
self-care behaviors, including food consumption behavior, cooking in familiar ways, consuming food together in companion groups, with the choice of the food being provided at the
discretion of the cooks. Among the factors affecting them were insufficient physical exercise
owing to fatigue or no extra time due to their overwhelming responsibility of providing family care. A minority group could not perform the physical activities due to senile frailness.
Most patients suffered stress from varying causes including debt. With regard to the factors
affecting tension, the most serious was the liability they faced. In the group discussion, the
patients and persons who took care of the patients criticized the health-care providers with
regard to patient behaviors on food consumption and regular exercise.


While I was confined to bed with the flu, my partner went to the local library to find me " something decent to read. " He returned with a kid's book! It's not often children's book makes it to the pages of a professional and academic journal, but Gael Jennings' humorous, yet informative, take on the gorier aspects of the history of medicine makes a fine exception. Jennings spent more than 10 years as a laboratory scientist, and she has a PhD in immunology. She then worked as a science journalist for the ABC (television and radio) for 13 years, and recently moved into freelance scientific journalism. Sick As, is her first book. Jennings presents a broad-brush view of the history of medicine through the eyes of a child aged about 10. " Mabel " receives a CD-ROM in the post, and as she navigates her way through the CD, she sees snapshots of medical history… Ambroise Pare discovering that oil of roses is a better balm for gunshot wounds than is boiling oil… Horace Wells painlessly removing his own tooth while under the influence of nitrous oxide (laughing gas)-the first case of operative anasthesia… Rene Laennec developing the stethoscope… Florence Nightingale nursing British soldiers in the Crimean War… Christiaan Barnard conducting the first heart transplant…. The choices presented to Mabel on her CD-ROM are also available to the reader, giving the book a " choose your own adventure " feel. Not just a recount of events, Jennings takes some literary licence to keep her work entertaining. A large breasted patient is said to have motivated Laennec to develop the stethoscope because her buxom physique prevented him from placing his ear directly onto her chest to listen to her heart, as was the usual practice for doctors of the day. Sir Almoth Wright, who determined how to prevent clotting in stored blood, is referred to as Sir Almost Right. Roland Harvey's comic illustrations further emphasise the lighter side of each situation, sometimes to the point of ridiculousness – Harvey's instructions on use of the stethoscope include a tip to not insert the ear-pieces into your nose. Blood, guts, gore and grime feature highly in this book. No offensive area of medical history escapes Jennings. Mabel is astounded by the paucity of women in medicine, the burning of female herbalists as witches, and the exclusion of women from medical schools until …


Introduction: The Hermansky-Pudlak syndrome is an autosomal recessive disease characterized by oculo cutaneous albinism, a bleeding diathesis and lysosomal accumulation of ceroid lipofuscin. Objectives: To do a comprehensive literature review of the clinicopathological findings in patients with the Hermasnky-Pudlak syndrome, its diagnosis, management, and treatment. Methods: A literature review of the Hermansky-Pudlak syndrome was done. Conclusion: Patients with the various genotypes leading to the Hermansky-Pudlak syndrome have multiple ocular and systemic manifestations with extensive genotypic and phenotypic variability. Co-management between Primary Physicians, Ophthalmologists, and other subspecialists is of outmost importance. Patients' co-management must be customized individually, taking into account patient's end goal, comorbidities, and bleeding diathesis. Genetic testing and counseling is of outmost importance in patients with the syndrome.


We propose a method for finding alternate features missing in the Lasso optimal solution. In ordinary Lasso problem, one global optimum is obtained and the resulting features are interpreted as task-relevant features. However, this can overlook possibly relevant features not selected by the Lasso. With the proposed method, we can provide not only the Lasso optimal solution but also possible alternate features to the Lasso solution. We show that such alternate features can be computed efficiently by avoiding redundant computations. We also demonstrate how the proposed method works in the 20 newsgroup data, which shows that reasonable features are found as alternate features.


The recent experiments in Tore Supra has focused on the optimisation of the RF heating systems (ICRH and LHCD) in order to achieve high power levels simultaneously over long durations. This leads to njected power levels n the range of 10 MW, which is representative of ITER operation in terms of average power density and heat exhaust capability. Successful operation has been achieved up to 9–10 MW for 20–30 s, using real‐time control of the antenna front face temperatures from nfrared measurements, and security on Cu and Fe brightness. The wave coupling was optimised for the two RF systems simultaneously, while at the same time minimising the hot spot formation due to RF sheath effects and interaction by fast particles (fast electrons accelerated n the near field of the LH wave and fast ions with large orbits created by ICRH). Local modification of the scrape‐off layer density around an ICRH antenna impacts on magnetcally connected LHCD antennas. The LH coupling either improves or deteriorates locally, dep...


The main condition for successful plants cultivation is their ability to adapt to a complex of environment factors. Climatic parameters (temperature, precipitation, humidity of air) takes a significant role in formation of soil processes, since water-air and thermal regimes of the soil, and, accordingly, the direction of biological processes are closely linked with them. In order to successfully grow sunflower Helianthus annuus L. it is necessary to know features of development most dangerous diseases – Phomopsis helianthi Munt , development of which depends on climatic conditions of the region and technology of growing this crop. In this regard, it is relevant to determine the optimal temperatures that contribute to development of Phomopsis helianthi Munt. on sunflower, annually in the Southern region ofUkraine. Under natural conditions, mushrooms are able to adapt to changes in environmental factors. Special effects on growth and development of the fungus are caused by temperature conditions that have a seasonal and daily fluctuation pattern. Therefore, there is a need to determine the most favorable and critical temperatures for development certain types of given pathogen in laboratory conditions in vitro . The aim of study was to determine the effect of temperature on growth and development of Diaporthe (Phomopsis) helianthi M. The isolation of Phomopsis helianthi M. in a pure culture and its identification was carried out at department of the Kherson regional phytosanitary laboratory. Potato glucose agar (PGA) was used in pure culture to isolate Phomopsis helianthi M. For inoculation of substrates, were used 2 weeks age cultures. The mycelium was sown in Petri dishes to the center surface of a dense nutrient agar with a small piece of the inoculum, about 5 ×5 mm in size, always of one density and age. Petri dishes were incubated in a thermostat with temperature of 0 °C; +5; +10; +15; +20; +25; +30 and +35 °C. It has been established that in culture vegetative growth of fungus Diaporthe (Phomopsis) helianthi M. occurs in a wide range of temperatures. Differences in the rate of mycelia growth are determined. The lower limit, which marked the growth of mycelium, is +5 °C, and the higher –  + 30 °C. The temperature of 0 and + 35 °C did not reveal a growth of mycelium. In vitro, the least intense growth of the fungus culture was detected under temperature conditions of +5 °C and +10 °C. The beginning of Phomopsis helianthi M. growth occurred at 5 and 4 days, respectively. More intense of mycelium growth was noted for temperature regimes of  +15 °C and + 20 °C. It has been shown that optimal temperature for isolates of Diaporthe (Phomopsis) helianthi growth is + 25 °C. Under these conditions, on the 8th day of incubation, complete colonization of the substrate in the Petri dish was recorded. After increasing temperature to + 30 °С, the intensity of growth of mycelium of the fungus decreased. Thus, the average monthly air temperature in the summer (20–23.8 °С) simultaneously with irrigation can contribute development of Diaporthe (Phomopsis) helianthi M. fungus on sunflower plants.

. Widely used in the practice of analysis and synthesis of automatic control systems of non-stationary dynamic systems, the method of "frozen coefficients" does not have a rigorous theoretical justification and does not always lead to the desired results. In this regard, to solve the problem of parametric synthesis of a non-stationary automatic control system of the course stability of the car, an algorithmic method is considered for choosing the variable parameters of the regulators of non-stationary objects, based on the direct calculation of the additive integral quadratic quality functional that reflects the set of requirements for the automatic regulator of a non-stationary object, followed by finding the values of the variable parameters a regulator delivering a minimum of quality functional, and the required values of the weight coefficients of the additive functional.

We have provided an overview on the profound impact of COVID‐19 upon older people with Alzheimer's disease and other dementias and the challenges encountered in our management of dementia in different health‐care settings, including hospital, out‐patient, care homes, and the community during the COVID‐19 pandemic. We have also proposed a conceptual framework and practical suggestions for health‐care providers in tackling these challenges, which can also apply to the care of older people in general, with or without other neurological diseases, such as stroke or parkinsonism. We believe this review will provide strategic directions and set standards for health‐care leaders in dementia, including governmental bodies around the world in coordinating emergency response plans for protecting and caring for older people with dementia amid the COIVD‐19 outbreak, which is likely to continue at varying severity in different regions around the world in the medium term.


Biochemical evidence has been collected which supports the proposition that the appearance of the staining reaction in tissue sections incubated in Fishman-Baker substrate solution is dependent on the activity of β-glucuronidase. It was first shown by quantitative analysis that the glucuronic acid is liberated into the medium simultaneously with the deposition of ferric-hydroxyquinoline as the hydrolysis of the substrate, 8-hydroxyquinoline glucosiduronic acid, proceeded. This demonstration was made both in a gel-β-glucuronidase model system and in incubation mixtures containing tissue sections. Next, it was established that the staining reaction was dependent on pH in a manner indistinguishable from the pH dependence of purified rat liver β-glucuronidase acting on 8-hydroxyquinoline glucosiduronic acid. Finally, the staining reaction was invariably prevented by adding to the Fishman-Baker substrate solution an appropriate amount of a second glucosiduronic acid beside that of 8-hydroxyquinoline. This inhibition was produced by naphthol AS-BI-β-glucosiduronic acid, a histochemical substrate for β-glucuronidase. Next, it was observed that the addition of p-nitrophenyl β-glucosiduronic acid to the digest prepared for each staining reaction inhibited the staining reactions of both. The use of the mixed substrate test suggests itself for application to the critical study of other enzymes.


The influence of amino acids on spore germination of Alternaria eassiae was investigated to develop a basis for improvement of mycoherbicide formulations. At a 1% concentration, the majority of amino acids exhibited little or no effect on spore germination in vitro. However, aspartic and glutamic acids stimulated germination, and serine, tryptophan, cysteine, and phenylalanine inhibited spore germination. Cysteine was the strongest inhibitor of germination and was active in the presence of potato dextrose broth, which is normally stimulatory. One percent cysteine reduced germination 96% after 4 h. Derivitization of the mercaptan or amino group but not the carboxylic acid group diminished the ability to inhibit spore germination. Cysteine also inhibited spore germination of Alternaria crassa and Alternaria macrospora. Application of cysteine reduced development of Alternaria leaf spot on cotton plants inoculated with A. macrospora. The results demonstrate diverse effects of amino acids on spore behavior an...


This paper offers a cognitive analysis of how visual representations can increase the chances of creativity, while also considering the ways in which they might hinder it. Specifically, it presents four cognitive mechanisms of creativity supported by visualisation: reinterpretation, abstraction, combination and mapping. Each process is described, analysed for potential benefits and pitfalls, and illustrated with examples. Although none of these processes guarantees creativity, together they can increase the odds of a creative moment. The paper concludes with a discussion of how to best prepare people to make use of visuals to support creative thought.


The role of the theatre lighting designer in the UK has traditionally been conceptualised using a model of 'designer' as someone who makes a prior imaginary act before the moment of performance, which is subsequently realised in performance through an essentially procedural, non-creative, process. In this paper I describe my recently completed PhD research in which I attempted a partial reinvention of theatre lighting as a professional arts practice, emphasising the live operation or 'performance' of lighting, rather than its design prior to the performance event, and combining the existing roles of the lighting desi ner and the lighting operator into what I term the lighting artist. The paper gives an overview of the aims and the conceptual and practical processes involved in the research, and discusses some of the methodological issues arising from this type of practice-research. I describe: a process of reading professional literature and first-person accounts 'archaeologically' (after Foucault); the conceptual basis on which I established a process of creative invention that was nevertheless rigorous in researchmethodological terms; some of the methodological issues of a research project in a collaborative performancemaking environment; and how I argued that a 'first-person' perspective fits within the established research practices of autoethnography and qualitative research.


Key management is an important issue in Wireless Sensor Networks (WSNs) for the secure communications among the nodes in the network. Based on the network settings and structure of the network, keys could be managed in various ways. Though there are quite a good number of key management schemes for WSNs, in this work, we present an enhanced heterogeneous tree based key management scheme for security of Wireless Sensor Networks (WSNs). Our scheme combines efficiently different key management techniques in each architecture level and also it has a dynamic key renewal process. Here, whenever a node is compromised, key renewal is done by one way hash functions and simple XOR operations. This combination gives the scheme good performance in terms of key storage overhead as well as resilience to the node capture attack. Our scheme shows relatively better performance compared to other existing heterogeneous schemes. Before presenting our scheme and its detailed analysis from multiple perspectives, we note down the related works to clarify this work's background and motivation.


Identifying patients early in their hospitalizations who need discharge planning to arrange special care dispositions is a difficult task. Failure to achieve early identification may result in unnecessarily prolonged hospital stays and a less orderly process of planning. In this study three brief rating instruments for identifying such patients were compared and found to have different performance characteristics when applied to a large population of patients admitted to a short–term, general medical and surgical hospital. Operational objectives for a discharge–planning screening program are specified and used as grounds for choosing among alternative screening instruments.


A 26-year-old man, the father of two children, was admitted on May 2, 1949, complaining of pain in the chest, coughing up blood, feverishness, and shortness of breath. His illness began four weeks before this date with a pleuritic pain in the left upper chest. Three days after first experiencing this pain he coughed up the first of daily half-cupfuls of blood-stained sputum. Intermittent fever had set in some three weeks before admission. Till then, but for these symptoms and signs, the patient had felt in fair general condition, and

Raccoons occur throughout the state of Texas. With the recent dispersal of raccoons in Castro County and increased interest in conservation of wetlands, there is a need for data on the importance of playa basins to raccoons as well as other wildlife in the area. This study was designed to evaluate the importance of playa basins to raccoons and document the significance of these basins with respect to; (1) home range and movements of raccoons and, (2) the den-site selection of raccoons. The study area selected was Castro County, Texas, and portions of Lamb and Hale Counties, Texas.

Raccoon home ranges varied from 795-3,845 ha. Adult males had the largest home range areas and juvenile females had the smallest. Adults and males moved significantly greater (P 0.10) between sex and age classes, indicating these characteristics acted independently of each other.

Sixty eight percent of the den sites were located on playa basins, 19% in croplands, 3% in pastures, and 10% in man-made structures All den sites located in vegetation were surrounded by cover 1.0 m or taller.

Playa basins were used significantly more (P<0.10) in proportion to their availability while croplands were used significantly less (P<0.10) in proportion to their availability. Pastures were used in proportion to their availability.

Playa basins were very important to raccoon use throughout the year, providing food, water, and cover; however, croplands, especially com fields were seasonally important to raccoon use.


In this study, an investigation is carried out to analyse the earthquake induced pounding between two insufficiently separated base isolated buildings considering the inelastic behaviour of the structures' response. The buildings are modelled as a four-storey and a three-storey system to simulate the structural behaviour. Moreover, non-linear viscoelastic impact elements are applied to model the collisions at different storey levels. The Duzce (1999) earthquake record is used to examine the seismic response of two buildings under the different ground motions in this study. A formulation of the equation of motion is presented in this study. Moreover, the dynamic response equations written for each building include effects of sliding and impact force on building. The resulting systems of second order constant coefficient equations are reformulated as a system of first order ordinary differential equations and solved using the ordinary differential equation solver of MATLAB. The parametric investigation has led to the conclusion that the peak displacement of the lighter and more flexible building is very sensitive to the structural parameters by varying gap size, storey mass, the friction coefficient for sliding and structural stiffness, whereas the effect on the behaviour of the heavier base isolated building was negligibly.


Purpose : The purpose of this study was to investigate the causal relationship between parenting styles and academic self-handicapping by mediating role of meta-cognitive and perfectionism skills. Methodology : The statistical population of the study consisted of all the second grade secondary school students in studying the academic year of 2017-18, in Bojnourd. A sample of 350 students was selected using multi-stage cluster sampling. To collect the data,(a) Alabama Parenting Questionnaire (APQ),(b) Metacognitive Skills Questionnaire(MCSQ)(Dowson,Mcinerney, 2004), (c) Perfectionism Scale (Hewitt, Flett (1991) and (d) Academic self-handicapping Scale (ASHS) (Schwinger, 2014) were used. Pearson correlation coefficient and Structure Equation Modeling were used to analyze the data. Findings : Findings showed that parenting styles directly to academic self-handicapping was not significant, But through the mediating role of meta-cognitive skills and perfectionism was significant. and the hypothetical model had good fit. Conclusion : teaching of the metacognitive skills to students will reduce the academic self-handicapping, and the increaseing of perfectionism will increase the likelihood of academic self-handicapping in the students.


The Serenitatis basin is prominent on the near side of the Moon, just east of Mare Imbrium. Originally thought to be one of the oldest lunar basins, re-interpretation of both geological relations and Apollo 17 isotopic data suggest instead that Serenitatis is one of the youngest basins, having formed in the Nectarian Period about 3.87 Ga ago. As part of our continuing effort to understand the geology of multi-ring basins on the Moon and to use basins as probes of the deep lunar crust, we here report results for the Serenitatis basin. Our examination of Serenitatis was stimulated in part by a new effort to re-examine the geology of the Apollo 17 landing site.


Avicenna Journal of Medicine / Jul-Sep 2012 / Vol 2 | Issue 3 Despite the apparent improved capacity of the health system, a number of challenges prevail which need to be addressed to reduce inequities in access to health care and to improve the quality of care; these include, addressing validity of the data, overall inequity, lack of transparency, inadequate utilization of capacity, inadequate coordination between providers of health services, uneven distribution of human resources, high turnover of skilled staff and leadership, inadequate number of qualified nurses and allied health professionals. More recently there has been an uncontrolled and largely unregulated expansion of private providers, resulting in uneven distribution of health and medical services among geographical regions. Standardized care and quality assurance and accreditation are major issues that need to be addressed; a recent study revealed that mortality rates among critically ill patients admitted to the intensive care units with severe 2009 H1N1 influenza A was 51% in Damascus compared to an APACHE II predicted mortality rate of 21% with a standardized mortality ratio of 2.4 (95% confidence interval: 1.7–3.2, P-value < 0.001).[4]

Abstract Recent investigations on the laser surface treatment of nickel-based alloys and austenitic stainless steels had shown that it is possible to increase additionally their pitting and erosion-corrosion resistance and also wear resistance as a result of laser surface alloying and laser surface melting. Austenitic stainless steel is one of the most widely used ferrous materials for structural applications in mild to very severe oxidizing environments due to its excellent corrosion resistance, mechanical strength and ductility. Therefore, an experimental investigation on ASTM 304 stainless steel was carried out to determine the influence of surface melting parameters, using a novel diode laser with rectangular and uniform energy distribution across the beam spot, on the shape, penetration depth, structure and microhardness of surface layers. The sample surface was treated using the continuous-wave high-power diode laser with a maximum output power of 2.5 kW. The surface of 304 stainless steel was melted in argon, nitrogen and air atmospheres using different laser output powers at a scanning speed of 500 mm/min. Surface layers after laser melting presented higher microhardness compared with the untreated material. In laser surface melting, a rapidly resolidified surface layer with refined grains of 300 μm thickness was obtained, and the penetration depth of surface layers was in the range 0.3-5.0 mm.


A diverse set of isoxazoles, with activity in three different disease categories, was reduced asymmetrically from pro-chiral ketones to chiral alcohols using the Corey-Bakshi-Shibata methodology at the α, β, and γ positions relative to the C-5-methyl of the isoxazole. The experiments described provide an easy route to hydroxylated isoxazoles that represent the common CYP-450 3A4 metabolic site.


Study on potency of Pemuda beach in Jimbaran, Southern Kuta District, Badung Regency. Pemuda beach is one of tourism destination located in Jimbaran which has a beautiful natural condition and also unique. Otherwise, only few people visit this place due to lack of information that tourists have such as hidden location of the beach and confusing boundaries of the beach from tourism properties. Therefore this research has a purpose to explore a potency that Pemuda beach has and also to investigate it potency and develop it using the 4A+1C concept. The method used was survey with several data collection techniques such as observation, interview, questionnaires and literature study. Then, data analyzed descriptively to explain the site potential which refers to the complete potential study process. Results indicated that the biophysical aspects (i.e. climate, soil, topography, visual description and also vegetation and animals) and socio-cultural aspects of the region have opportunity to be developed as tourist areas. This studi also illustrated that attractions, accessability, amenities, ancilliary and community involvement for Pemuda beach were potencially to be developed. Hence, by understanding the potentials and the possibility to develop the area, this study expected to give more knowledge to the visitor. Further, it is also recommended to local society together with the government to use this exploration study as an additional reference to develop the beach.


The near surface wind shear characteristics were analyzed in this article,using 10 m to 120 m gradient wind observation data from May to October in 2009,which came from China's wind power resources professional observation network.The results show that: 1) The wind shear near surface presents regular variation trend: with large wind shear index before sunrise and after sunset,and it is gradually dropping with the near surface temperature increasing,and with the lowest shear index when the near surface temperature comes to a peak value,and then,with the sunset and the ground temperature drop,the shear index rising up again,until the next sunrise/sunset period.2) With different distributions of local sea or lake and land and with different roughness of the underlying surface,the wind shear indexes can be reduced to the following several types: the typical land type,the sea land effect difference type,lake or river land effect difference type,the special differences terrain(canyon) type,shear index partial large type and the special type.3) It is much more obvious at low level,near 30 m,than the relative high level,between 50 m to 70 m from the wind shear characteristics of the different gradient.So it is instability near the 30 m height in China.In this study,the analysis data sequence is short,and this may become the negative factor reflecting the universality law of the near surface wind shears characteristics in China,but it still becomes an important reference reflecting the near surface different gradient wind shear distributions and variation characteristics of the wind power resources rich area in China.It is expected that this study can provide some technical reference in building wind farm and in using near ground wind power resources in China.


Objective
To evaluate the mean blood flow(MF) and pulsatility index(PI) of individual and sequential saphenous vein grafts in posterior descending artery(PDA) in the same patient undergone off-pump coronary artery bypass grafting(OPCABG).

Methods
140 patients with coronary artery disease were studied. Sequential surgical technique using single large saphenous vein was used in grafts of diagnostic artery(DIAG)(side-side), obtuse marginal artery(OM)(side-side), and PDA(end-side). Bulldog clamps were used to temporarily arrest the anastomoses of DIAG and OM near the large saphenous vein. Thus the sequential graft became to the single graft, the MF and PI of PDA were recorded in the simulating single graft by the transit-time flow measurement(TTFM), after that, bulldog clamps were removed and the MF and PI of PDA were recorded again in the real sequential graft. The data were compared. Six months later after surgery, coronary CTA were done in all patients in clinic.

Results
The MF of single graft and sequential graft was(22.5±13.1)ml/min and(22.2±12.9)ml/min(P>0.05). The PI of single graft and sequential graft was 2.43±0.94 and 2.38±0.88(P>0.05). The patency of all grafts is good in all patients after 6 months follows-up.

Conclusion
There ars no hemodynamic differences between individual and sequential grafts in PDA. It is reasonable that the short-term surgical result is the same in individual and sequential grafts in PDA.

Key words:
Coronary arteriosclerosis; Coronary artery bypass, off-pump; Instantaneous flow; Comparative study

Navigation and information retrieval on the Web are not easy tasks; the challenge is to extract information from the large amount of data available. Most of this data is unstructured, which makes the application of existing data mining techniques to the Web very difficult. However, new semantic structures that improve the results of Web Mining are currently being developed in the Web. This paper presents how one of these semantic structures XML topic maps can be exploited to help users find relevant information on the Web. This paper is organised as follows: first, we introduce XML topic maps in the context of Tim Berners-Lee's Semantic Web vision. Then, we show how topic maps allow to characterise and "clean" Web data through the definition of a profile; this is achieved by the analysis of a lattice generated by a classification algorithm called Galois algorithm. This profile may be used to evaluate the relevance of a web site with regard to a specific request on a traditional search engine. We finally explain how data on the Web can be clustered, organised and visualised in different ways so as to enhance users' navigation and understanding of these documents. Additional characterization of web data is provided by joint author David Dodds method for computing context and similarity. It uses OpenCYC DAML-OIL and Upper Ontology to leverage perception and development of the characterization. We present the results obtained with topic maps and compare and contrast our similarity measures and clusters, the ones obtained with the Galois lattice and the ones obtained with OpenCYC DAML-OIL.


Fault diagnosis and condition monitoring of rotating machinery has drawn considerable attention. The complex structure of rotating machinery and poor working conditions cause two challenges: weak signature detection (WSD) and weak compound fault separation (WCFS). A superior method should realize these two functions simultaneously. This paper proposed a multidimensional blind deconvolution method based on cross-sparse filtering (Cr-SF) for WSD and WCFS, which can enhance the weak signature and decompose the different components from compound fault adaptively without any preprocessing and priori knowledge. Cross kurtosis pursuit (CKP), a novel filter selection technology, is proposed for determining the final filters. The experimental and simulated signals verified the performance of the proposed algorithm. The robustness is also investigated using the success rate of repeated experiments. The results indicate that Cr-SF can handle different fault compounding modes under the strong noise environment and perform strong robustness and noise adaptability.

The morphological development of eggs of the grasshopper Chorthippus brunneus, laid during successive periods through a single season, was closely monitored in the field at a site in NW England. Eggs within the same clutch developed synchronously. However, there were significant differences between clutches laid at the same time, reflecting spatial variation in microclimate (and possibly maternal effects and/or genetic differences). Eggs laid early in the season entered diapause and hatched relatively synchronously in the following spring. Eggs laid later failed to reach the diapause-stage before winter, but hatched, albeit late and with greater variance. Diapause was averted in these eggs. Plasticity in the nature of diapause has been documented from laboratory studies of many insect species (including C. brunneus,) but this study directly relates the incidence of such developmental plasticity to oviposition date and seasonal temperature cycles in the field. The adaptive significance of diapause aversion and the evolutionary consequences for female reproductive behaviour are considered.


As the most prominent feature of interlanguage,fossilization is a complex and essential topic in the field of SLA research. Various causes,in spite quantity of them are only theories,have been studied by different researchers from multiple points of view. Daiwei Dong(1990) has pointed out that virtually every inaccurate cause leads to language fossilization. This paper tries to conclude update causes of fossilization.

At the cellular level, numerous nanocues guide the cells to adhere, interact, proliferate, differentiate, etc. Understanding and manipulating the cellular functions in vitro, necessitates the elucidation of these nanocues provided to the cells by the extracellular matrix (ECM), neighbouring cells or in the form of ligands. DNA nanotechnology is a biocompatible, flexible and a promising molecular level toolkit for mimicking cell‐cell and cell‐matrix interactions. In this review, we summarize various advances in cell‐matrix, cell‐cell and cell receptor‐ligand interactions using DNA nanotechnology as a tool. We also provide a brief outlook on the current challenges and the future potentials of these DNA‐based nanostructures so as to inspire novel innovations in the field.


Many studies related to the policy of street vendors relocation in various cities in Indonesia, even in the world. However, there is still limited research examining the cultural variability of government and street vendors. Culture is not the only variable that can influence the behavior of street vendors in responding to the policies, but omnipresent cultural existence becomes a major factor in communication of government policies. The research was carried out in a qualitative explanatory with the main focus on the implementation of street vendor policy relocation in Yogyakarta City, Indonesia. Data collection techniques were carried out through in-depth interviews with the actors or communicators in the communication of relocation policies to street vendors. The success or failure of public policy implementation has many determinants. From a system perspective, a policy is in the frame of the environment which requires the integration of all elements which can influence it. This research has found that culture is the main determinant which can be one of the determinants of successful communication, creating compliance, forming positive opinions, conformity, and building consensus on the policy of street vendors relocation in Yogyakarta City, Indonesia.


The article explores the application of artificial intelligence in the field of accounting. Although artificial intelligence technology can improve accounting efficiency and accuracy, there are also a series of issues such as data quality, data security and privacy, model interpretability and auditing, and the balance between artificial intelligence technology and human professional literacy. Therefore, in application, it is necessary to balance the relationship between technology and human professional literacy, establish data quality control, data security protection, model interpretability, and audit mechanisms, and enhance the skills and knowledge of accountants to adapt to the development of artificial intelligence technology.


Solar pumps are used on small farms, private homes, orchards, etc.  It is most economical to power the pump directly from the PV array, store water in a tank, and then distribute it. The test bench installed at the research unit of Ghardaia URAER is used to test and characterize different PV pumping systems and the results of this characterization are presented in this paper. A novel method of water consumption management through a Photovoltaic water pumping system, installed on real well has been studied. The method consists of controlling the water usage via the storage tank level and the consumption. The main purpose is to adapt the variation of the water consumption by an end user. The designed control system is based on the control of water supply from a submersible solar powered pump according to the variation of water demand. Taking into account the permanent solar energy supply and the availability of the water. The control design is satisfied by a Fuzzy Logic Controller (FLC), that senses the varying level of water in the storage tank and the end user requirement, so that the storage tank or a reserve tank is filled up, for its satisfactory performance. The Through different environmental condition recorded, the proposed system design has been simulated and validated by Matlab toolbox. The obtained results averred a very high controlling effectiveness of both the water management and the PV pumping system operation. Keywords : PV water pumping, water level, fuzzy logic, Storage


In this paper, we study and compare Si versus Ge pMOS FinFETs at advanced node dimensions using ensemble Monte Carlo simulations. It is found that due to large external resistance, lack of stressing methods, smaller bandgap, larger dielectric constant, and increased variability that in the absence of major innovation, Ge is not an ideal candidate for channel replacement material of pMOS in future CMOS technology generation FinFETs. In order for Ge to compete with Si, it would at a minimum require a stressing mechanism and improved contact resistance, but leakage and variability would still be a concern for low-power applications.


The study was conducted during Kharif 2010 in arid region of Rajasthan involving 108 legume growers to find out the association of socioeconomic attributes with economic motivation of legume growers. The independent variables, such as age, education, landholding, farmpower, social participation socioeconomic status and economic motivation were measured by the standard scale developed for this purpose. The study revealed that about half of respondents were middle aged with large landholding and educated up to middle standard. Majority of them belonged to medium (66.66%) and high (17.59%) socioeconomic status. It was observed that socioeconomic attributes such as age, land holding, farm power and socioeconomic status significantly associated with economic motivation whereas education and social participation were not associated with it. The information sources mostly utilized by farmers were the village level worker/agriculture supervisor/krishakmitra followed by radio, neighbours, input dealers and field demonstrations.


Abstract : This paper describes a new method for computing correlations which is particularly well suited for image processing. The method, called hierarchical discrete correlation, or HDC, is computationally efficient, typically requiring two or three orders of magnitude fewer computational steps than direct correlation or correlation computed in the spatial frequency domain using the Fast Fourier transform. In addition the method simultaneously generates correlations for kernels (operators) of many sizes. These kernels closely approximate the Gaussian probability distribution, so that the correlation is equivalent to low pass filtering. The operators commonly used in image processing can be readily obtained from sums and differences of Gaussian-like correlations at nearby image points.

We propose a scheme for realizing a quantum controlled phase gate via an unconventional geometric quantum computation with two nonresonant quantum dots trapped in a photonic crystal cavity. In this system, the quantum dots simultaneously interact with a large detuned cavity mode and strong driving classical light fields. During the gate operation, the quantum dots undergo no transitions, while the cavity mode is displaced along a closed path in the phase space. In this way, the system can acquire geometric phases conditional upon the states of the quantum dots and realize the controlled phase gate.


Until the recent release of a draft GST ruling, the only public document from the Australian Taxation Office which considered the GST consequences arising from transactions under a loyalty reward program was a media release issued by the Commissioner in 2000. There have, however, been a number of private rulings issued on the subject to particular taxpayers. In addition, a number of VAT cases dealing with loyalty programs which have been handed down in the United Kingdom recently have highlighted the lack of guidance in Australia. The Commissioner's recent draft ruling, GSTR 2011/D3, released on 24 August 2011, now provides the Australian Taxation Office's public view of how transactions under loyalty reward programs should be treated for GST purposes. This article analyses the draft ruling, the differences between this now public view of the Commissioner to prior private rulings, and examines the possible consequences of these differences for the loyalty program industry.

The clinical syndrome of subacute bacterial endocarditis occurs frequently and is today a well recognized entity. Little has been added to knowledge of the subject since Libman's publications. 1 It is now well known that while Streptococcus viridans is the most common cause of this disease, a large variety of other bacteria may produce a similar picture. Among these are Bacillus influenzae, Enterococcus, Meningococcus, Bacillus diphtheriae, Pneumococcus, Gonococcus and organisms of the Brucella group. However, the occurrence of a similar clinical picture caused by higher bacteria is rare. Only 1 case—that of Jervell, 2 in which the condition was caused by Leptothrix—is to be found in the literature. For this reason, the case to be described is of unusual interest, since the causative agent of the disease was found to be Actinomyces bovis. REPORT OF CASE History. —W. J., a 24 year old American-born Jew, a chiropodist, was admitted to


Software reliability allocation is a complicated multiple-criteria decision process which involves many factors such as cost, performance, functional complexity and testing. For medical devices, safety is an extremely critical factor that it must be emphasized in the system software development from the early stages. In this paper, we demonstrate an intuitive approach to incorporate safety into reliability allocation. This approach starts with allocating reliability to software modules associated with specific safety feature through functional decomposition and fault tree analysis, and finalizes the allocation for each software module by considering all safety features. This approach can provide a conservative and practical safety-related reliability allocation in an easy-to-use way at software planning and design stages. The proposed approach is shown in detail with a simplified real case.


Robotics is being studied in several fields due to the impact it has had on the media, the industry, and the academy. Besides the many undergraduate and graduate programs created around the world, robotics is also being used as a teaching tool. In these learning processes, it is required that students can build robotic prototypes to be used in a wide variety of topics like history, mathematics, language, geography, physics, etc. So, this generates the need that both, teachers and students, must have specific knowledge of robotics. In this sense, this work proposes a curriculum in the area of educational robotics for kids from 6 to 18 years old. This curriculum couple up to knowledge acquired in basic education. Also, it is proposed a set of skills of mastery taking into consideration the taxonomy of Bloom. This curriculum is being applied in the robotics club of the San Pablo Catholic University in Peru since 2014 and, as an example, in this paper we present a summary of our evaluation process using a rubric proposed previously by the robotics club. The results obtained (not only related to the rubric-based evaluation, but to the achievements in international competitions) show the relevance of our approach.


In the context of Publish/Subscribe systems (Pub/Sub), Peer-to-Peer (P2P) solutions based on Distributed Hash Tables (DHT) offer efficient functionalities such as event routing flexibility, scalability, load balancing and fault tolerance. For event routing, it uses event identifiers computed by event encryption. Likewise, Pub/Sub systems based on ontologies offers well adapted semantic expression capabilities allowing consumers and providers to easily describe services' requests and properties. Thanks to the ontologies, semantic reasoning allows to provide enhanced event discovering. Indeed, DHT-based systems are based on traditional matching algorithms while in ontology-based systems, users can use various literals semantically equivalent but syntactically different expressions in order to describe their requirements. However, both approaches present limitations in terms of: semantic expression restrictions for the first one and scalability issues for the second one. Our solution consists in combining the advantage of both of them, by taking advantage of the semantic capabilities of ontologies at local domain level and the scalable P2P-DHT solutions at inter-domains level. This paper proposes an approach based on a community-wide ontology in order to allow publishers and subscribers to use a common semantic space to characterize production and consumption of resources and services. Based on this ontology, a P2P network based on distributed reasoners (i.e. inference engines) will be able to evaluate if a specific content belongs to an ontology-based community topic. Thus, we use these topics to compute keys for routing events in a DHT.


Wireless sensor networks (WSN) also known as wireless sensor and actuator networks (WSAN). These are distributed autonomous sensors for monitoring environmental or physical conditions, like sound, temperature pressure, etc. and used for passing their data via the network to a main location. These are measurement tools which are equipped with transmitters for converting the signals into a radio transmission from process control instruments. Receiver interprets the radio signal after that converts the wireless signal to a desired or specific output, like a data or Analog current analysis via computer software.

Abstract Aim and objectives The present study was intended to assess the biocompatibility of newly formulated materials such as zinc oxide (ZO) admixed with ajwain oil (A) as well as ajwain eugenol (E) (1:1 ratio) against ZOE through an animal model as root canal obturating materials in deciduous teeth. Materials and methods The study involved randomly selected 24 albino rats, which were divided into three groups based on test materials. Two polyethylene tubes (PETT) (8 mm long × 1 mm internal diameter) were inserted into connective tissues of the dorsal side on either side of each rat viz empty tube (negative control) and another containing test material (test group). Animals were sacrificed at the end of the 7th and 21st days. PETT with surrounding connective tissues were excised. Histopathological evaluations of the material's biocompatibility were done by determining inflammatory tissue responses. Non-parametric tests such as Kruskal–Wallis and Mann–Whitney U were used for statistical analysis (p < 0.05). Results Histopathological examination on the 7th day showed increased polymorphonuclear cells for all test materials compared to the negative control (p = 0.92), suggesting acute inflammation. The inflammation subsided gradually after 21 days (p = 0.48). The lymphocytes increased after 21 days for all the materials indicating chronic inflammation (p = 0.79), as well as fibroblasts (p = 0.34) and capillaries (p = 0.35), indicating healing and repair. Conclusion The newly formulated obturating materials were found to be biocompatible compared to ZOE. How to cite this article Dahake PT, Joshi SS, Kale YJ, et al.
