Fetal Tendinous Connection Between the Tensor Tympani and Tensor Veli Palatini Muscles: A Single Digastric Muscle Acting for Morphogenesis of the Cranial Base.

Science.gov (United States)

Rodríguez-Vázquez, José Francisco; Sakiyama, Koji; Abe, Hiroshi; Amano, Osamu; Murakami, Gen

2016-04-01

Some researchers contend that in adults the tensor tympani muscle (TT) connects with the tensor veli palatini muscle (TVP) by an intermediate tendon, in disagreement with the other researchers. To resolve this controversy, we examined serial sections of 50 human embryos and fetuses at 6-17 weeks of development. At 6 weeks, in the first pharyngeal arch, a mesenchymal connection was found first to divide a single anlage into the TT and TVP. At and after 7 weeks, the TT was connected continuously with the TVP by a definite tendinous tissue mediolaterally crossing the pharyngotympanic tube. At 11 weeks another fascia was visible covering the cranial and lateral sides of the tube. This "gonial fascia" had two thickened borders: the superior one corresponded to a part of the connecting tendon between the TT and TVP; the inferior one was a fibrous band ending at the os goniale near the lateral end of the TVP. In association with the gonial fascia, the fetal TT and TVP seemed to provide a functional complex. The TT-TVP complex might first help elevate the palatal shelves in association with the developing tongue. Next, the tubal passage, maintained by contraction of the muscle complex, seems to facilitate the removal of loose mesenchymal tissues from the tympanic cavity. Third, the muscle complex most likely determined the final morphology of the pterygoid process. Consequently, despite the controversial morphologies in adults, the TT and TVP seemed to make a single digastric muscle acting for the morphogenesis of the cranial base. © 2016 Wiley Periodicals, Inc.

Full Text Available Bektaşilik, which was established in Sulucakarahöyük as the central and improved by Hacı Bektaş Veli after his coming from Central Asia to Anatolia and providing unity and integrity in Anatolia, has been a subject matter to the literary work in the context of intertextuality and in order to presented a representative type of Hacı Bektaş Veli. İsmet Kırdar’s comic book, is one of these works. In Hacı Bektaş Velî, character types, legendary life, historical aspect, nationalism, Bektaşilik, and collective memory are abundant. According to this, Hacı Bektaş Veli, conveys features of an exalted “veli type,” which is among idealized types. There are proximal connections between his legendary life and his life in the novel and between the official history and the history in the novel. In the novel Hacı Bektaş Velî, Hacı Bektaş Veli is portrayed as a figure that have Turkishİslamic consciousness. The novel, which includes various elements of Bektaşilik, also indicates Hacı Bektaş Veli’s position in the society in terms of collective memory. Therefore, the aim of this article is both to introduce a less known novel and to analyze elements of Bektaşilik with respect to literary appreciation

A ringed fascia lata graft without peritendinous areolar tissue encircling the levator veli palatini and superior pharyngeal constrictor muscles gradually shrinks to reduce velopharyngeal incompetence, functioning as an intravelar palatal lift.

Science.gov (United States)

Fujita, Kenya; Matsuo, Kiyoshi; Yuzuriha, Shunsuke

2013-01-01

We have previously reported that fascia lata grafts with peritendinous areolar tissue used to treat severe congenital blepharoptosis gradually shrink within 6 weeks postoperatively and maintain long-term shrinkage of 15.5% on average. Accordingly, it seemed possible that a fascia lata graft without peritendinous areolar tissue would shrink more than the one with peritendinous areolar tissue in a clinical setting. We evaluated this possibility in a patient with Klippel-Feil syndrome having postoperative deep atonic nasopharynx. In combination with intravelar veloplasty and palatal lengthening with modified bilateral buccinator sandwich pushback, a ringed fascia lata without peritendinous areolar tissue encircling the levator veli palatini and superior constrictor muscles was grafted to cure severe velopharyngeal incompetence. Obstructive sleep apnea did not occur following surgery. Pharyngoscopy, videofluoroscopy, and nasometry showed no amelioration of velopharyngeal incompetence at 1 month postoperatively, but marked velopharyngeal incompetence reduction was evident at 4 months and 2 years after surgery. The extended recovery period suggests that the anticipated postoperative shrinkage of the ringed fascia lata without peritendinous areolar tissue played a more prominent role than intravelar veloplasty and palatal lengthening, which posteroinferiorly elongated the atonic soft palate. Although the pharyngeal flap procedure is the most popular technique for treatment of velopharyngeal incompetence, it is sometimes accompanied by respiratory complications. Thus, the gradual postoperative shrinkage of a ringed fascia lata graft encircling the velopharyngeal muscles functions as an intravelar palatal lift and may be an additional surgical method with less respiratory complications to narrow atonic nasopharyngeal port.

Hierarchical micro-nano structured Ti6Al4V surface topography via two-step etching process for enhanced hydrophilicity and osteoblastic responses

Energy Technology Data Exchange (ETDEWEB)

Moon, Byeong-Seok; Kim, Sungwon; Kim, Hyoun-Ee; Jang, Tae-Sik, E-mail: cgamja@snu.ac.kr

Hierarchical micro-nano (HMN) surface structuring of dental implants is a fascinating strategy for achieving fast and mechanically stable fixation due to the synergetic effect of micro- and nano-scale surface roughness with surrounding tissues. However, the introduction of a well-defined nanostructure on a microstructure having complex surface geometry is still challenging. As a means of fabricating HMN surface on Ti6Al4V-ELI, target-ion induced plasma sputtering (TIPS) was used onto a sand-blasted, large-grit and acid-etched substrate. The HMN surface topography was simply controlled by adjusting the tantalum (Ta) target power of the TIPS technique, which is directly related to the Ta ion flux and the surface chemical composition of the substrate. Characterization using scanning electron microscopy (SEM), transmission electron microscopy (TEM), and laser scanning microscopy (LSM) verified that well-defined nano-patterned surface structures with a depth of ~ 300 to 400 nm and a width of ~ 60 to 70 nm were uniformly distributed and followed the complex micron-sized surface geometry. In vitro cellular responses of pre-osteoblast cells (MC3T3-E1) were assessed by attachment and proliferation of cells on flat, nano-roughened, micro-roughened, and an HMN surface structure of Ti6Al4V-ELI. Moreover, an in vivo dog mandible defect model study was used to investigate the biological effect of the HMN surface structure compared with the micro-roughened surface. The results showed that the surface nanostructure significantly increased the cellular activities of flat and micro-roughened Ti, and the bone-to-implant contact area and new bone volume were significantly improved on the HMN surface structured Ti. These results support the idea that an HMN surface structure on Ti6Al4V-ELI alloy has great potential for enhancing the biological performance of dental implants. - Highlights: • A micro-nano-hierarchical (MNH) surface structure on Ti6Al4V-ELI was fabricated via TIPS

Identification of hot spot area of sediment contamination in a lake system using texture characteristics.

Science.gov (United States)

Sheela, A M; Letha, J; Joseph, Sabu; Thomas, Jobin

2013-04-01

Texture plays an important role in the identification of polluted stretch in a lake system. The organic matter as well as toxic elements get accumulated in the finer sediments. The aim of the work is to show the spatio-temporal distribution of texture of the lake sediment (Akkulam-Veli lake, Kerala) and to identify the hot spot areas of contamination. Hot spot areas vary with seasons. During PRM, (premonsoon), the upstream portion of the Akkulam lake is the hot spot. During MON (monsoon), the downstream portion of the Akkulam lake and the upstream portion of the Veli lake are the hot spots. During POM (postmonsoon), hot spot area is the downstream portion of the Akkulam lake. This methodology can be used for the quick identification of hot spots in water bodies.

Full Text Available U radu je prikazano delovanje sile prednaprezanja na armiranobetonski ram (u daljem tekstu AB ram. Posmatrani sistem je statički neodređen sa dva ukleštenja. Na njega deluje opterećenje prednaprezanje kablom silom Nk=600 kN, kao i sopstveno opterećenje. Visina rama je 6.00 m, a osovinski razmak 20.00 m. Opterećenje od sopstvene težine elemenata je od rigle i stuba. Opterećenje konstrukcije usled prednaprezanja spada u unutrašnja opterećenja, koja zamenjujemo ekvivalentnim opterećenjem koje predstavlja spoljašnje opterećenje. Proračun je izvršen metodom sila i metodom deformacija, kao i u softverskom programu 'Tower'. Metodom sila se uklanja ukleštenje i preseku se omogućava obrtanje. Statički neodređena veličina tada je moment ukleštenja. Kod metode deformacije sve statičke i deformacijske veličine izražavaju se putem izvesnog broja međusobno nezavisnih deformacijskih veličina, koje su određene iz uslova ravnoteže sistema. Broj nezavisnih deformacijskih neodređenih veličina predstavlja deformacijsku neodređenost nosača. Sve deformacijski neodređene veličine mogu se svrstati u dve grupe: prvu grupu čine uglovi obrtanja na krajevima kruto vezanih štapova, a drugu grupu komponente pomeranja čvorova. / The effects of prestressing forces on a reinforced concrete frame are shown in the paper. The structure is a statically indeterminate frame with two fixed supports. The load is due to tendon prestressing with Nk = 600 kN and due to self-weight of columns and beam. The columns height is 6.00 m and the beam span is 20.00 m. Effects of prestressing can be replaced by an external equivalent load. Calculations are performed by the force method, by the direct stiffness method and using the 'Tower' software. The rotational restraints are released at fixed supports and the restraint moments are calculated by the force method. The direct stiffness method uses the members' stiffness relations for computing member forces and

Full Text Available This study is a part of a larger project aiming to produce new, healthy, and tasty food ingredients from oat. Germination and different heating processes can be used to improve the texture and flavour of cereals. In this study effects of germination and wet and dry heating on the microstructure, instrumental structure and sensory properties of two oat varieties were assessed. The microstructure of native, germinated, autoclaved and extruded grains of the hulled cv. Veli and hull-less cv. Lisbeth was examined by light microscopy, the texture was measured by determining the milling energy and hardness of the grains and sensory characteristics were evaluated with descriptive sensory profile analysis. In cv. Veli the cells of the starchy endosperm were smaller than in cv. Lisbeth and ß-glucan was concentrated in the subaleurone layer. In cv. Lisbeth ß-glucan was evenly distributed in the starchy endosperm. The grains of cv. Lisbeth were more extensively modified in the germination process than the grains of cv. Veli, otherwise the effects of processing on the grains of the two cultivars were similar. Germination caused cell wall degradation, autoclaving and extrusion cooking caused starch gelatinization. Autoclaving resulted in the hardest perceived texture in oat. Gelatinization of starch appeared to contribute more to the hardness of oat groats than the cell wall structure. Of the instrumental methods used in this study the milling energy measurement appeared to be the most useful method for the analysis of the effects of processing on grain structure.;

The development of glossopharyngeal breathing and palatal myoclonus in a 29 year old after scuba diving

Directory of Open Access Journals (Sweden)

Thomas AR

2011-02-01

Full Text Available Palatal myoclonus is a rare movement disorder characterized by brief, rhythmic involuntary movements of the soft palate. Palatal myoclonus is further subdivided into “essential palatal tremor” (EPT and “symptomatic palatal tremor” (SPT. EPT is characterized by involvement of the tensor veli palatini, myoclonus that might persist during sleep, as well as ear clicks, usually the patient’s presenting complaint. The MRI and neurological exam are normal in EPT. SPT is characterized by involvement of the levator veli palatini and myoclonus which consistently perseveres during sleep. The MRI shows olivary hypertrophy and clinical features may include ataxia, dysarthria and nystagmus, depending on the size of the lesion1. Glossopharyngeal breathing is a technique used by deep-sea divers to increase lung vital capacity, which is also useful in patients with ventilator dependence from poliomyelitis and Duchenne muscular dystrophy. To date there have been no reported cases of palatal myoclonus and glossopharyngeal breathing occurring simultaneously. We present the case of a 29 year-old female with palatal myoclonus and glossopharyngeal breathing after scuba-diving.

Piecing Together—A Methodological Bricolage

Directory of Open Access Journals (Sweden)

Ainslie Yardley

2008-05-01

Full Text Available The use of narrative, reflective, and creative processes as interpretive tools has been considered by many critics to be naïvely humanistic and even romantically impulsive. This contribution challenges those views by putting performative research methods into practice—using the method to test the methodology. The meta-text, in which embedded texts (visual, audio-visual and literary challenge, inform and enhance each other's meaning, has at its heart a digital mapping system that acts as a guiding link that provides alternative interpretive angles and mediating possibilities. The inclusion here of many kinds of text acknowledges that there are multiple ways in which human cognitive networks process information and make creative leaps. This contribution directly presents the case for multi-layered narrative inquiry as a paradigm of ethical activity. The researcher is seen here as a bricoleur, a maker of patchwork, a weaver of stories; one who assembles a theoretical montage through which meaning is constructed and conveyed according to a narrative ethic that is neither naïvely humanistic, nor romantically impulsive—but rather one that stimulates an inclusive and dynamic dialogue between the researcher and her audience.

Hierarchical micro-nano structured Ti6Al4V surface topography via two-step etching process for enhanced hydrophilicity and osteoblastic responses.

Science.gov (United States)

Moon, Byeong-Seok; Kim, Sungwon; Kim, Hyoun-Ee; Jang, Tae-Sik

2017-04-01

Hierarchical micro-nano (HMN) surface structuring of dental implants is a fascinating strategy for achieving fast and mechanically stable fixation due to the synergetic effect of micro- and nano-scale surface roughness with surrounding tissues. However, the introduction of a well-defined nanostructure on a microstructure having complex surface geometry is still challenging. As a means of fabricating HMN surface on Ti6Al4V-ELI, target-ion induced plasma sputtering (TIPS) was used onto a sand-blasted, large-grit and acid-etched substrate. The HMN surface topography was simply controlled by adjusting the tantalum (Ta) target power of the TIPS technique, which is directly related to the Ta ion flux and the surface chemical composition of the substrate. Characterization using scanning electron microscopy (SEM), transmission electron microscopy (TEM), and laser scanning microscopy (LSM) verified that well-defined nano-patterned surface structures with a depth of ~300 to 400nm and a width of ~60 to 70nm were uniformly distributed and followed the complex micron-sized surface geometry. In vitro cellular responses of pre-osteoblast cells (MC3T3-E1) were assessed by attachment and proliferation of cells on flat, nano-roughened, micro-roughened, and an HMN surface structure of Ti6Al4V-ELI. Moreover, an in vivo dog mandible defect model study was used to investigate the biological effect of the HMN surface structure compared with the micro-roughened surface. The results showed that the surface nanostructure significantly increased the cellular activities of flat and micro-roughened Ti, and the bone-to-implant contact area and new bone volume were significantly improved on the HMN surface structured Ti. These results support the idea that an HMN surface structure on Ti6Al4V-ELI alloy has great potential for enhancing the biological performance of dental implants. Copyright © 2016 Elsevier B.V.

We attempted to image the eustachian tube (ET) and its surrounding tissues by high-resolution computed tomography (HR-CT). Twenty-two normal subjects (44 ears) without middle ear problems were studied, and a patient with severe patulous ET was also studied as an abnormal case. In our device of multiplanar reconstruction technique, we were able to obtain the clear reconstructed images of the ET lumen as well as of its surrounding tissues (bone, ET cartilage, tensor veli palatini muscle, levator veli palatini muscle, Ostmann's fat tissue, tensor tympani muscle, internal carotid artery) at any desired portion, either parallel or perpendicular to the long axis of the ET. However, the exact borders between the ET cartilage and the muscles, Ostmann's fat tissue and the tubal gland were not clearly identified. In the severe case of patulous ET, the ET lumen was widely opened at each cross-sectional image from the pharyngeal orifice to the tympanic orifice, in contrast with its being closed at the cartilaginous portion in the normal cases. In addition, the fat tissue and glands around the ET lumen were not clearly identified in this case. We suggest that this method will lead to better understanding of the ET-related diseases such as patulous ET. (author)

TiO 2 nanotubes were grafted on the surface of cpTi, Ti6Al4V and Ti6Al4V-ELI with the aim to provide a new podium for human pre-osteoblast cell (MC3T3) adhesion and proliferation. The surface morphology and chemistry of these alloys were examined with scanning electron microscopy and energy dispersive x-ray spectroscopy. TiO 2 nanotubes were further characterized by cyclic potentiodynamic polarization tests and electrochemical impedance spectroscopy. The vertically aligned nanotubes were subjected to pre-osteoblast cell proliferation in order to better understand cell–material interaction. The study demonstrated that these cells interact differently with nanotubes of different titanium alloys. The significant acceleration in the growth rate of pre-osteoblast cell adhesion and proliferation is also witnessed. Additionally, the cytotoxicity of the leached metal ions was evaluated by using a tetrazolium-based bio-assay, MTS. Each group of data was operated for p < 0.05, concluded one way ANOVA to investigate the significance difference. - Highlights: • TiO 2 nanotubes were grafted on cpTi, Ti6Al4V and Ti6Al4V-ELI via anodization. • MC3T3 cells interact differently with nanotubes of different titanium alloys. • TiO 2 nanotubes have a positive impact on the osteoblast cell viability.

Repair of a submucous cleft palate by W-pushback and levator repositioning without incision to the nasal mucosa.

Science.gov (United States)

Hwang, Kun

2012-03-01

The author created an innovative method of W-pushback and levator repositioning without having to make an incision to the nasal mucosa for submucous cleft palate repair.The W-shaped mucoperiosteal flap is outlined where the 2 peaks of W are the alveolar processes of both canine teeth and the midpoint of W is the anterior limit of the cleft notch of the hard palate. A short incision, medial to and behind the maxillary tuberosity and curved forward onto the palate and extended forward just medial to the alveolar process, is joined by a second incision from the apex of the cleft to the region of the canine tooth. The W-shaped mucoperiosteal flap is raised until the midline notch of the hard palate is exposed. The nasal mucosa and abnormally inserted levator veli palatini muscle to the posterior border of the hard palate bone are detached. By leaving the nasal mucosa intact, the detached levator veli palatini muscle is approximated at the midline and so the zona pellucida is obliterated. The cleft uvulas are cut in half and closed. The approximated W-flap is joined to the small anterior flap by 1 or more sutures (the W-pushback).Three patients were operated on with this technique without serious complications.The author believes that this method can make the levator sling and increase the length of the soft palate without making an incision to the nasal mucosa.

This work quantitatively evaluates the effects induced by susceptibility characteristics of materials commonly used in dental practice on the quality of head MR images in a clinical 1.5T device. The proposed evaluation procedure measures the image artifacts induced by susceptibility in MR images by providing an index consistent with the global degradation as perceived by the experts. Susceptibility artifacts were evaluated in a near-clinical setup, using a phantom with susceptibility and geometric characteristics similar to that of a human head. We tested different dentist materials, called PAL Keramit, Ti6Al4V-ELI, Keramit NP, ILOR F, Zirconia and used different clinical MR acquisition sequences, such as "classical" SE and fast, gradient, and diffusion sequences. The evaluation is designed as a matching process between reference and artifacts affected images recording the same scene. The extent of the degradation induced by susceptibility is then measured in terms of similarity with the corresponding reference image. The matching process involves a multimodal registration task and the use an adequate similarity index psychophysically validated, based on correlation coefficient. The proposed analyses are integrated within a computer-supported procedure that interactively guides the users in the different phases of the evaluation method. 2-Dimensional and 3-dimensional indexes are used for each material and each acquisition sequence. From these, we drew a ranking of the materials, averaging the results obtained. Zirconia and ILOR F appear to be the best choice from the susceptibility artefacts point of view, followed, in order, by PAL Keramit, Ti6Al4V-ELI and Keramit NP.

1987-03-01

Magnetic resonance imaging (MRI) of the nasopharynx and the eustachian tube was performed in five patients with cleft palate and compared with the results of those without this anomaly. Various degrees of deformity of the eustachian tube cartilage were found in cleft palate patients. The levator veli palatini muscles were situated more laterally in cleft palate patients than in normal subjects. Also, changes in the position of these muscles after palatoplasty were clearly depicted by MRI. Besides several autopsy reports, this is the first demonstration of the characteristic anomaly around the eustachian tube by a non-invasive method.

Magnetic resonance imaging (MRI) of 16 cleft palate patients was undertaken after a palatoplasty to evaluate the postoperative status of the nasopharyngeal soft tissue, the soft palate, and a pharyngeal flap. As MRI revealed no abnormal findings in the nasopharyngeal muscle of all 16 patients, we concluded that the palatoplasty had normalized the positioning and volume of the levator veli muscle and the muscle sling of the palate. Further, although most of the pharyngeal flaps had an adequate inner muscle volume, some flaps had shrunk and 1 flap was found to have more mucous tissue than muscle. These pharyngeal flap deficits may have been due to rough flap handling during the surgical intervention. Therefore, gentle manipulation of such flaps during the course of surgery is emphasized.

Full Text Available In the history of poetry adventure from ancient times to date, thepoet’s invariable characteristic has been his creativity glorified all thetime. However, creativity criteria may vary in different periods. The firstdescription of Poetry and Poet go back to Poetics of Greek philosopherAristotle, who had an understanding close to modern literary theoryand performed the first systematic study on the literature principlesfunctioning and organization based on perceptible data. The mostimportant aspect of Poetics in terms of the subject of this study is thedescription of the poetry language as a specific area of language and theclassification of the functional elements of this structure. However,poetry elements, which have become a tradition in historical processwith changing sense and expectation of art due to many reasons, wereneeded to be reviewed again and caused the pursuit of novelty in 20thcentury. The opposition to the tradition and pursuit of novelty have ledus to find intersection point between Russian futurism and the “Garip”movement in Turkish poetry, although they are not followers of oraffected by each other. Shershenevich and Orhan Veli, explained theiropposition to the traditional and stereotype attitudes towards poetry foryears such as vocabulary, rhyme and meter and rhetorical devices intheir poetry as well as their poetic knowledge by giving justifications.While reviewing the characteristics of poetry, Russian futuristssupported the tendency to neologism, and Garip poets supported thetendency to simplified language of the people that new poetryconception is addressed to. When discussing the common and differentpoint of views of three different authors from different ages, in the poetictext we have studied by giving examples from 20th century Russian andTurkish poetries, it was found out that the idea welcomed for long thatthe poetry is valuable in proportion to its compliance with specific formshas not been accepted.

Re-rigging Othering: Subversive Infantilisation in Contemporary Bosnian-Herzegovinian Prose

Directory of Open Access Journals (Sweden)

Fedja Borčak

2014-12-01

Full Text Available In this article I put forward the concept of subversive infantilisation to designate a phenomenon in contemporary Bosnian literature, which by using a certain kind of childish outlook on the world undermines paternalistic and balkanist Western discourse on Bosnia and Herzegovina. By analysing primarily the portrayal of the role of mass media in a few literary texts, principally books by Nenad Veličkovié and Miljenko Jergovié, I highlight the way in which these texts 're-rig' and by means of irony and exaggeration illuminate the problematic logic inherent in the subject position from which one represents the other. Textual characteristics of subversive infantilisation are contextualised further and seen as a discursive continuation of experiences of the 1990s war in Bosnia and Herzegovina.

Location of the levator veli palatini insertion following levator retropositioning, palatal pushback, and pharyngeal flap procedures.

A long-term cineradiographic follow-up study of twenty patients with velo-pharyngeal incompetence fails to demonstrate predictable retrodisplacement of the levator insertion following combined levator retropositioning, pushback, and pharyngeal flap procedures. Simple levator retropositioning gave posterior displacement in the two patients evaluated. Patients with normal or posterior levator insertions pre-operatively all demonstrated post-operative anterior displacement following pharyngeal flap procedures, either alone or in combination with pushback. Anterior levator displacement may be the result of scar contraction or division of the levator sling (during insetting of a pharyngeal flap). Pre-operative and post-operative speech evaluation demonstrated substantial improvement in all except 3 patients; 2 of the poor speech results were patients with demonstrated levator retrodisplacement on post-operative cineradiography.

BACKGROUND: This study was carried out to analyze the relationship between clinical factors and velopharyngeal closure (VPC) in cleft palate patients. METHODS: Chi-square test was used to compare the postoperative velopharyngeal closure rate. Logistic regression model was used to analyze independent variables associated with velopharyngeal closure. RESULTS: Difference of postoperative VPC rate in different cleft types, operative ages and surgical techniques was significant (P=0.000). Results of logistic regression analysis suggested that when operative age was beyond deciduous dentition stage, or cleft palate type was complete, or just had undergone a simple palatoplasty without levator veli palatini retropositioning, patients would suffer a higher velopharyngeal insufficiency rate after primary palatal repair. CONCLUSIONS: Cleft type, operative age and surgical technique were the contributing factors influencing VPC rate after primary palatal repair of cleft palate patients. PMID:22279464

A group of villages in Kollam district of Kerala, southern part of India are exposed to a higher dose of natural radiation than global average. Yet no adverse health effects have been found in humans, animals and plants in these areas. The present study was carried out to understand whether radiation affects the quantity and quality of flavonoids in plants grown in this area of high radiation, and to assess the effect of feeding flavonoid rich fraction (FRF) of the two varieties of banana to rats on their biochemical parameters like lipids, lipid peroxides and antioxidant enzyme levels. A total of 42 albino rats were equally divided into 7 groups. Rats fed laboratory diet alone were grouped under group I (normal control). Groups II and V received flavonoid rich fraction (FRF) from the fruits of two varieties of Musa paradisiaca, Palayamkodan and Rasakadali respectively from normal background radiation area (Veli) and treated as controls. Rats of groups III and IV received FRF of Palayamkodan from high background radiation areas (HBRAs) - Neendakara and Karunagappally respectively while groups VI and VII received FRF of Rasakadali from HBRAs. At the end of the experimental period of 45 days, lipids, lipid peroxides and antioxidant enzymes from liver, heart and kidney were analyzed. FRF of Palayamkodan and Rasakadali varieties showed significant hypolipidaemic and antioxidant activities. But these activities were found to be lowered in plants grown in HBRAs, particularly in Karunagappally area. Of the two, Palayamkodan variety was more effective in reducing lipids and lipid peroxides. MDA and hydroperoxides were significantly diminished in rats given FRF of banana from Veli (control area) only. FRF from plants grown in HBRAs exerted inhibition in the activities of antioxidant enzymes in the liver of rats and this inhibitory effect was maximum in rats fed FRF from Karunagappally. Banana grown in HBRAs is of lower quality with less efficient antioxidant system

Smart variations: Functional substructures for part compatibility

KAUST Repository

Zheng, Youyi

2013-05-01

As collections of 3D models continue to grow, reusing model parts allows generation of novel model variations. Naïvely swapping parts across models, however, leads to implausible results, especially when mixing parts across different model families. Hence, the user has to manually ensure that the final model remains functionally valid. We claim that certain symmetric functional arrangements (sFarr-s), which are special arrangements among symmetrically related substructures, bear close relation to object functions. Hence, we propose a purely geometric approach based on such substructures to match, replace, and position triplets of parts to create non-trivial, yet functionally plausible, model variations. We demonstrate that starting even from a small set of models such a simple geometric approach can produce a diverse set of non-trivial and plausible model variations. © 2013 The Author(s) Computer Graphics Forum © 2013 The Eurographics Association and Blackwell Publishing Ltd.

Bicykl Jejího Veličenstva: O národním habitu a sociologické komparaci

Full Text Available Why are things different on the other side of national borders; and how can this be explained sociologically? This inaugural lecture tries to answer these questions, starting from the example of the bicycle in the Netherlands. It distinguishes four processes that have contributed to increasing similarity within nations: growing interdependence within nations; increasing density of networks and institutions; vertical diffusion of styles and standards; and the development of national we-feelings. Together, these processes have contributed to the development of national habitus: increasing similarities within nations, and increasing differences between people living in different countries. These processes have reached their apex in the second half of the twentieth century. Since then, they have diminished, leading to increasing variations within countries, and growing similarities between comparable groups in different countries. This analysis poses new questions and challenges for sociologists. First, it leads us to rethink comparative research: what are we comparing when we compare nations, and is this still a viable unit of analysis? Second, it leads us to consider how the transfer of styles and standards occurs in our informalized, globalized, and mediatized age. Third, sociologists should analyse the new forms of inequality resulting from these processes, such as the growing rift between ‘locals’ and (bike-loving cosmopolitans.

Microstructure and mechanical properties of a novel β titanium metallic composite by selective laser melting

International Nuclear Information System (INIS)

Vrancken, B.; Thijs, L.; Kruth, J.-P.; Van Humbeeck, J.

2014-01-01

Selective laser melting (SLM) is an additive manufacturing process in which functional, complex parts are produced by selectively melting consecutive layers of powder with a laser beam. This flexibility enables the exploration of a wide spectrum of possibilities in creating novel alloys or even metal–metal composites with unique microstructures. In this research, Ti6Al4V-ELI powder was mixed with 10 wt.% Mo powder. In contrast to the fully α′ microstructure of Ti6Al4V after SLM, the novel microstructure consists of a β titanium matrix with randomly dispersed pure Mo particles, as observed by light optical microscopy, scanning electron microscopy and X-ray diffraction. Most importantly, the solidification mechanism changes from planar to cellular mode. Microstructures after heat treatment indicate that the β phase is metastable and locate the β transus at ∼900 °C, and tensile properties are equal to or better than conventional β titanium alloys

Treatment of the cleft palate has evolved over a long period of time. Various techniques of cleft palate repair that are practiced today are the results of principles learned through many years of modifications. The challenge in the art of modern palatoplasty is no longer successful closure of the cleft palate but an optimal speech outcome without compromising maxillofacial growth. Throughout these periods of evolution in the treatment of cleft palate, the effectiveness of various treatment protocols has been challenged by controversies concerning speech and maxillofacial growth. In this article we have evaluated the results of Pinto's modification of Wardill-Kilner palatoplasty without radical dissection of the levator veli palitini muscle on speech and post-op fistula in two different age groups in 20 patients. Preoperative and 6-month postoperative speech assessment values indicated that two-layer palatoplasty (modified Wardill-Kilner V-Y pushback technique) without an intravelar veloplasty technique was good for speech.

The aim of this study was to assess diagnoses and outcomes of infants with 2 or more cranial neuropathies identified using orofacial electromyography (EMG). This retrospective study involved 90 patients. Diagnoses took into account clinical, radiological, and genetic data. EMG examined the orbicularis oculi, genioglossus, and levator veli palatini muscles, and blink responses. To evaluate outcome, neurological disability, respiratory complications, and feeding difficulties were recorded. The patients had malformation syndromes (59), encephalopathies (29), or no underlying disorders (2). Neurogenic EMG signs were detected in a mean of 4 muscles, reflecting a mean of 3 affected nerves. EMG identified a higher number of neuropathies than clinical examination alone (82 vs. 31, facial; 56 vs. 2, pharyngeal; 25 vs. 3, hypoglossal). Poor outcome and death were more frequent when EMG identified ≥4 affected nerves (P = 0.02). EMG highlights multiple cranial neuropathies that can be clinically silent in infants with malformation syndromes or encephalopathies. © 2015 Wiley Periodicals, Inc.

Atacama Large Millimetre Array observations show a non-detection of carbon monoxide around the four most luminous asymptotic giant branch (AGB) stars in the globular cluster 47 Tucanae. Stellar evolution models and star counts show that the mass-loss rates from these stars should be ˜1.2-3.5 × 10-7 M⊙ yr-1. We would naïvely expect such stars to be detectable at this distance (4.5 kpc). By modelling the ultraviolet radiation field from post-AGB stars and white dwarfs in 47 Tuc, we conclude that CO should be dissociated abnormally close to the stars. We estimate that the CO envelopes will be truncated at a few hundred stellar radii from their host stars and that the line intensities are about two orders of magnitude below our current detection limits. The truncation of CO envelopes should be important for AGB stars in dense clusters. Observing the CO (3-2) and higher transitions and targeting stars far from the centres of clusters should result in the detections needed to measure the outflow velocities from these stars.

Full Text Available Existi ng literature has not yet defi ned a clear-cut relati onship between ownership structure and capital structure. This study aims to contribute to this controversial argument by examining the impact of internal (managerial ownership and external ownership on fi nancing preferences using the case of non-fi nancial fi rms listed on Karachi stock exchange during the period of 2008-2012. Our results suggest that the external ownership has a signifi cant eff ect on capital structure in accordance with the presence of blockholders. In contrast, the internal ownership has a complicated eff ect; it shows signifi cant positi ve and negati ve relati onship to leverage at lower and certain higher proporti on of managerial shareholding respecti vely. Besides, the combined analyses suggest that the presence of blockholders negates the impact of managerial ownership on capital structure. This implies that the presence of large and dominant shareholders in Pakistani fi rms may have caused a bias for debt fi nancing to protect their voti ng power and returns.

Biodiversity of Three Backwaters in the South West Coast of India

2014-01-01

Full Text Available For the conservation of biodiversity, it is not sufficient to preserve the living organisms or their gametes alone, because keeping fishes in aquaria or their gametes in freezers cannot conserve the full range of biodiversity which is due to the loss of the ecological complexity in their original habitats. For promoting richer biodiversity in the future, more complexity in biological communities is essential in their natural environments. In order to prevent depletion of biodiversity due to environmental alterations or other ways, it is necessary to understand how the diversity of life particularly at the species level is maintained and it is equally necessary to know how the terminal extinction of species takes place under natural conditions. Moreover, a database on fishery resources of the concerned environment is essential to make decision about specific programmes on conservation of fish germplasm resources. Hence, the present study aims to quantify the fish and shellfish resources of the selected backwaters such as Kadinamkulam, Veli, and Poonthura to know the real stocks present in such environments.

The pterygoid venous plexus (PVP) is an important factor in the mechanism of eustachian tube (ET) closure under conditions that can cause increased venous pressure in the head, such as during neck compression and postural change from the sitting/standing to the recumbent position. The symptoms of patulous ET are usually improved by neck compression or postural change (from sitting/standing to recumbent position). Venous congestion around the ET and/or gravitational change may be involved in the changing degree of symptoms, but its mechanism is not understood. This study investigated whether the PVP is involved. The dimensions of soft tissues surrounding ET were measured on magnetic resonance images before and after neck compression. The lateral pterygoid muscle became enlarged after neck compression. Simultaneously, the volume of venous plexus observed between the medial pterygoid muscle and tensor veli palatini muscle was increased. Such enlargement was probably due to blood pooling in the PVP, resulting in protrusion of the ET anterior wall to the luminal side, and decreased ET patency.

Brain lesions in congenital nystagmus as detected by computed tomography

Lo, Chin-Ying

1982-01-01

Computed tomography (CT) was performed in a series of 60 cases with congenital nystagmus. The type of nystagmus was pendular in 20 and jerky in 40 cases. The age ranged from 3 months to 13 years. Abnormal CT findings of the central nervous system were detected in 31 cases (52%). There were 5 major CT findings: midline anomalies, cortical atrophy, ventricular dilatation, brain stem atrophy and low density area. The midline anomalies involved cavum septi pellucidi, cavum Vergae, cavum veli interpositi and partial agenesis of corpus callosum. The abnormal CT findings were more prominent in pendular type than in jerky type. The incidence of congenital nystagmus and positive CT findings were the same in the first and the second birth. There was a history of abnormalities during the prenatal or perinatal period in 28 out of the 60 cases (47%). This feature seemed to play a significant role in the occurrence of congenital nystagmus. The observed organic lesions in the central nervous system by CT would contribute to the elucidation of pathomechanism of congenital nystagmus. (author)

Full Text Available The Alevi are a religious minority in Turkey. It is a heterogeneous group including millions of Muslims who do not profess the major Sunni movement. During the time of the Ottoman Empire they were often persecuted as heretics. The Alevi and the Bektashi rise from the same origins which stretch back to the 13century to the theory of dervish Hadji Bektash Veli. In the first case it was concerned mainly rural inhabitants and in the second case it was concerned urban inhabitants – members and adherents of the dervish order Bektashi. Alevi Islam is called “Folk Islam”. It connects the elements of Shi’a Islam, Sufi movement, Christianity and pre- Islam systems of belief. The Alevi are despised by the major society because they do not stand aloof from drinking alcohol and they do not keep the Five Pillars of Islam which the orthodox Islam is based on. There was created a separate genre of anecdotes about the Alevi-Bektashi. This contribution introduces the main principles of their belief and ceremonies and brings also illustrations of some anecdotes.

2018-04-26

A fundamental and important challenge in modern datasets of ever increasing dimensionality is variable selection, which has taken on renewed interest recently due to the growth of biological and medical datasets with complex, non-i.i.d. structures. Naïvely applying classical variable selection methods such as the Lasso to such datasets may lead to a large number of false discoveries. Motivated by genome-wide association studies in genetics, we study the problem of variable selection for datasets arising from multiple subpopulations, when this underlying population structure is unknown to the researcher. We propose a unified framework for sparse variable selection that adaptively corrects for population structure via a low-rank linear mixed model. Most importantly, the proposed method does not require prior knowledge of sample structure in the data and adaptively selects a covariance structure of the correct complexity. Through extensive experiments, we illustrate the effectiveness of this framework over existing methods. Further, we test our method on three different genomic datasets from plants, mice, and human, and discuss the knowledge we discover with our method. Copyright © 2018. Published by Elsevier Inc.

A morphometric CT study of Down's syndrome showing small posterior fossa and calcification of basal ganglia

1984-01-01

We report characteristic and morphometric changes of cranial computed tomography (CT) with increasing age in 56 patients with Down's syndrome aged from 0 month to 37 years. Patients were compared with 142 normal controls aged 0 to 59 years. Width of ventricles, Sylvian fissures, posterior fossa, pons and cisterna magna were measured on CT. The incidences of the cavum septi pellucidi, cavum vergae and cavum veli interpositi and high density in the basal ganglia were examined. There was high incidence (10.7%) of bilateral calcification of basal ganglia in Down's syndrome, although that of pineal body and choroid plexus calcification was similar in Down's syndrome and controls. Basal ganglia calcification is more frequently seen in young Down's syndrome and may be related to the premature aging characteristic of Down's syndrome. The CT in Down's syndrome showed relatively small posterior fossa, small cerebellum, small brain stem and relatively large Sylvian fissures in those under one year of age. There was a high frequency of midline cava and large cisterna magna. There were no significant atrophic changes on CT except after the fifth decade comparing with controls. (orig.)

Treatment of Palatal Myoclonus with Botulinum Toxin Injection

Full Text Available Palatal myoclonus is a rare cause of pulsatile tinnitus in patients presenting to the otolaryngology office. Rhythmic involuntary contractions of the palatal muscles produce the pulsatile tinnitus in these patients. Treatment of this benign but distressing condition with anxiolytics, anticonvulsants, and surgery has been largely unsuccessful. A few investigators have obtained promising results with botulinum toxin injection into the palatal muscles. We present a patient with palatal myoclonus who failed conservative treatment with anxiolytics. Unilateral injection of botulinum toxin into her tensor veli palatini muscle under electromyographic guidance resolved pulsatile tinnitus in her ipsilateral ear and unmasked pulsatile tinnitus in the contralateral ear. A novel method of following transient postinjection symptoms using a diary is presented in this study. Botulinum toxin dose must be titrated to achieve optimal results in each individual patient, analogous to titrations done for spasmodic dysphonia. Knowledge of the temporal onset of postinjection side effects and symptomatic relief may aid physicians in dose titration and surveillance. We present suggestions on titrating the botulinum toxin dose to optimal levels. A review of the literature on the use of botulinum toxin for palatal myoclonus and some common complications are discussed.

The near-infrared radius-luminosity relationship for active galactic nuclei

2011-05-01

Black hole masses for samples of active galactic nuclei (AGNs) are currently estimated from single-epoch optical spectra. In particular, the size of the broad-line emitting region needed to compute the black hole mass is derived from the optical or ultraviolet continuum luminosity. Here we consider the relationship between the broad-line region size, R, and the near-infrared (near-IR) AGN continuum luminosity, L, as the near-IR continuum suffers less dust extinction than at shorter wavelengths and the prospects for separating the AGN continuum from host-galaxy starlight are better in the near-IR than in the optical. For a relationship of the form R∝Lα, we obtain for a sample of 14 reverberation-mapped AGN a best-fitting slope of α= 0.5 ± 0.1, which is consistent with the slope of the relationship in the optical band and with the value of 0.5 naïvely expected from photoionization theory. Black hole masses can then be estimated from the near-IR virial product, which is calculated using the strong and unblended Paschen broad emission lines (Paα or Paβ).

Purpose: To develop and evaluate a protocol for the anatomic depiction and functional testing of the auditory tube with the use of MR imaging. Methods: Eleven volunteers were included into this study. For the morphological assessment, the imaging protocol included axial and coronal T 2 -weighted turbo-spin echo sequences (T R /T E =3194/100 ms) and a T 1 -weighted gradient echo sequence (T R /T E =42/4.6 ms). For the functional test a dynamic turbo-gradient echo sequence (TFE) with spectral fat suppression (T R /T E =15/6,2 ms; 4 sec) was obtained using the single slice technique before and during the Valsalva manoeuvre. Results: With multi-slice sequences, the osseous part of the auditory tube, the tubal cartilage (middle and lateral lamina), the ciliated epithelium, Ostmann's adipose body and the levator and tensor veli palatini muscles were delineated in all cases. During the Valsalva test, opening of the auditory tube was demonstrated in 20 of the 22 investigated sides using the dynamic TFE single slice sequence. Conclusions: The introduced MRI protocol allow visualization of the opening of the auditory tube and provides detailed anatomical information of the nasopharynx. Comprehensive morphological and functional evaluation of the auditory tube becomes possible within a single examination. (orig.) [de

Reflex otalgia is a predictive and prognostic parameter for local control in patients with oropharynx carcinoma. Can a morphologic correlate of this important symptom be detected by MRI? Thirty-six patients were prospectively evaluated by MRI before radical radiotherapy. Sixteen patients had reflex otalgia; 20 did not. The oropharynx and adjacent regions were analyzed. Alteration was defined as effacement of anatomical structures, signal alteration or enhancement after contrast medium administration. The χ 2 -test was used to compare categorical parameters. In patients with reflex otalgia, alteration of the following structures innervated by the glossopharyngeal nerve were found significantly more often: nasopharynx, hard palate, superior constrictor pharyngis muscle, palatine tonsil, palatopharyngeus muscle, palatoglossus muscle, stylopharyngeus muscle, hyoglossus muscle and preepiglottic space. No difference was found for the muscles of mastication, levator and tensor veli palatini muscles, styloglossus muscle, genioglossus muscle, intrinsic muscles of the tongue, digastric muscles, mucosal surface of the lateral and posterior pharyngeal wall, uvula, valleculae, parapharyngeal space and larynx. An alteration of structures innervated by the glossopharyngeal nerve was visualized on MRI significantly more often when reflex otalgia was present. Involvement of structures innervated by other cranial nerves did not show the same association with ear pain. (orig.)

The Dentato-Rubro-Olivary Tract: Clinical Dimension of This Anatomical Pathway

Full Text Available Symptomatic palatal tremor is potentially the result of a lesion in the triangle of Guillain-Mollaret (1931 and is associated with hypertrophic olivary degeneration (HOD which has characteristic MR findings. The triangle is defined by dentate efferents ascending through the superior cerebellar peduncle and crossing in the decussation of the brachium conjunctivum inferior to the red nucleus, to finaliy reach the inferior olivary nucleus (ION via the central tegmental tract. The triangle is completed by ION decussating efferents terminating on the original dentate nucleus via the inferior cerebellar peduncle. We can demonstrate the anatomy of this anatomical triangle using a clinical case of palatal tremor presenting with bilateral subjective pulsatile tinnitus along with the pathognomonic MR findings previously described. The hyperintense T2 signal in these patients may be permanent, but the hypertrophied olive normally regresses after 4 years. The temporal relationship between the evolution of the histopathology and the development of the palatal tremor remains unknown as does the natural history of the tremor. Botox injection at the level of tensor and levator veli palatini insertion have been used to treat patients with disabling tremor synchronous tinnitus. A lesion involving the triangle can have a quite varied clinical expression.

Full Text Available I macrofagi sono cellule del sistema immunitario che svolgono un ruolo fondamentale nel meccanismo di difesa dell’ospite contro gli agenti patogeni. Attualmente è ancora poco chiara la dinamica del loro intervento e della risposta umorale nel favorire l’attività fagocitaria nei confronti di Mycoplasma mycoides subsp. mycoides small colony (Mmm-SC, agente eziologico della pleuropolmonite contagiosa bovina (PPCB. Questo studio è stato condotto al fine di valutare le modificazioni morfologiche della superficie macrofagica in seguito all’infezione in vitro con Mmm-SC in presenza di siero immune bovino. L’analisi morfologica dei macrofagi è stata condotta su colture, 6 ore dopo l’infezione, utilizzando l’analisi tridimensionale della microscopia elettronica a scansione. I macrofagi non infettati, in presenza di siero negativo o immune, e i macrofagi infettati con Mmm-SC, in assenza di siero, hanno mostrato solo lievi modificazioni della loro superficie. Al contrario, in colture di macrofagi infettati e in presenza di siero immune sono state osservate marcate modificazioni della superficie cellulare, come ampi veli e filopodi (indicatori di attivazione cellulare, e piccoli aggregati di micoplasmi in stretto contatto con le membrane macrofagiche. I risultati suggeriscono che la risposta umorale specifica per Mmm-SC può contribuire a innescare l’attività fagocitaria dei macrofagi.

Titanium alloys are playing a vital role in the field of biomaterials due to their excellent corrosion resistance and biocompatibility. These alloys enhance the quality and longevity of human life by replacing or treating various parts of the body. However, as these materials are in constant contact with the aggressive body fluids, corrosion of these alloys leads to metal ions release. These ions leach to the adjacent tissues and result in adverse biological reactions and mechanical failure of implant. Surface modifications are used to improve corrosion resistance and biological activity without changing their bulk properties. In this investigation, electropolishing and magnetoelectropolishing were carried out on commercially pure titanium, Ti6Al4V, and Ti6Al4V-ELI. These surface modifications are known to effect surface charge, chemistry, morphology; wettability, corrosion resistance, and biocompatibility of these materials. In vitro cyclic potentiodynamic polarization tests were conducted in phosphate buffer saline in compliance with ASTM standard F-2129-12. The surface morphology, roughness, and wettability of these alloys were studied using scanning electron microscope, atomic force microscope, and contact angle meter, respectively. Moreover, biocompatibility of titanium alloys was assessed by growing MC3T3 pre-osteoblast cells on them.

Analgesia is becoming increasingly important in veterinary medicine, and little research has been performed that examined pain control in avian species. Tramadol is a relatively new drug that provides analgesia by opioid (mu), serotonin, and norepinephrine pathways, with minimal adverse effects. To determine the pharmacokinetics of tramadol and its major metabolite O-desmethyltramadol (M1) in eagles, 6 bald eagles (Haliaeetus leucocephalus) were each dosed with tramadol administered intravenously (4 mg/kg) and orally (11 mg/kg) in a crossover study. Blood was collected at various time points between 0 and 600 minutes and then analyzed with high-performance liquid chromatography to determine levels of tramadol and M1, the predominate active metabolite. The terminal half-life of tramadol after intravenous dosing was 2.46 hours. The maximum plasma concentration, time of maximum plasma concentration, and terminal half life for tramadol after oral dosing were 2156.7 ng/ml, 3.75 hours, and 3.14 hours, respec vely. In addition, the oral bioavailability was 97.9%. Although plasma concentrations of ramadol and M1 associated with analgesia in any avian species is unknown, based on the obtained data and known therapeutic levels in humans, a dosage of 5 mg/kg PO q12h is recommended for bald eagles. Pharmacodynamic studies are needed to better determine plasma levels of tramadol and M1 associated with analgesia in birds.

Stardust (Sdt) and Discs-Large (Dlg) are membrane-associated guanylate kinases (MAGUKs) involved in the organization of supramolecular protein complexes at distinct epithelial membrane compartments in Drosophila. Loss of either Sdt or Dlg affects epithelial development with severe effects on apico-basal polarity. Moreover, Dlg is required for the structural and functional integrity of synaptic junctions. Recent biochemical and cell culture studies have revealed that various mammalian MAGUKs can interact with mLin-7/Veli/MALS, a small PDZ-domain protein. To substantiate these findings for their in vivo significance with regard to Sdt- and Dlg-based protein complexes, we analyzed the subcellular distribution of Drosophila Lin-7 (DLin-7) and performed genetic and biochemical assays to characterize its interaction with either of the two MAGUKs. In epithelia, Sdt mediates the recruitment of DLin-7 to the subapical region, while at larval neuromuscular junctions, a particular isoform of Dlg, Dlg-S97, is required for postsynaptic localization of DLin-7. Ectopic expression of Dlg-S97 in epithelia, however, was not sufficient to induce a redistribution of DLin-7. These results imply that the recruitment of DLin-7 to MAGUK-based protein complexes is defined by cell-type specific mechanisms and that DLin-7 acts downstream of Sdt in epithelia and downstream of Dlg at synapses.

What goes up must . . . Keep going up? Cultural differences in cognitive styles influence evaluations of dynamic performance.

Past research on dynamic workplace performance evaluation has taken as axiomatic that temporal performance trends produce naïve extrapolation effects on performance ratings. That is, we naïvely assume that an individual whose performance has trended upward over time will continue to improve, and rate that individual more positively than an individual whose performance has trended downward over time-even if, on average, the 2 individuals have performed at an equivalent level. However, we argue that such naïve extrapolation effects are more pronounced in Western countries than Eastern countries, owing to Eastern countries having a more holistic cognitive style. To test our hypotheses, we examined the effect of performance trend on expectations of future performance and ratings of past performance across 2 studies: Study 1 compares the magnitude of naïve extrapolation effects among Singaporeans primed with either a more or less holistic cognitive style, and Study 2 examines holistic cognitive style as a mediating mechanism accounting for differences in the magnitude of naïve extrapolation effects between American and Chinese raters. Across both studies, we found support for our predictions that dynamic performance trends have less impact on the ratings of more holistic thinkers. Implications for the dynamic performance and naïve extrapolation literatures are discussed. (PsycINFO Database Record (c) 2018 APA, all rights reserved).

Calcium channel-dependent molecular maturation of photoreceptor synapses.

Full Text Available Several studies have shown the importance of calcium channels in the development and/or maturation of synapses. The Ca(V1.4(α(1F knockout mouse is a unique model to study the role of calcium channels in photoreceptor synapse formation. It features abnormal ribbon synapses and aberrant cone morphology. We investigated the expression and targeting of several key elements of ribbon synapses and analyzed the cone morphology in the Ca(V1.4(α(1F knockout retina. Our data demonstrate that most abnormalities occur after eye opening. Indeed, scaffolding proteins such as Bassoon and RIM2 are properly targeted at first, but their expression and localization are not maintained in adulthood. This indicates that either calcium or the Ca(V1.4 channel, or both are necessary for the maintenance of their normal expression and distribution in photoreceptors. Other proteins, such as Veli3 and PSD-95, also display abnormal expression in rods prior to eye opening. Conversely, vesicle related proteins appear normal. Our data demonstrate that the Ca(V1.4 channel is important for maintaining scaffolding proteins in the ribbon synapse but less vital for proteins related to vesicular release. This study also confirms that in adult retinae, cones show developmental features such as sprouting and synaptogenesis. Overall we present evidence that in the absence of the Ca(V1.4 channel, photoreceptor synapses remain immature and are unable to stabilize.

Full Text Available The purpose of this study is to determine the effects on motivation and success within the application of blended learning environments in the foreign language class. The research sample is formed by third grade students studying in the tourism and hotel management programs of the faculty for tourism and the faculty of economics and administrative sciences at the Nevsehir Hacı Bektas Veli University (Turkey in fall semester of the 2012-2013 academic year. The research group consists of 62 students and there of 35 students belong to the experimental group and the other 27 persons belong to the control group. While the experimental group was subject to 14 hours online and 6 hours traditional face to face learning, the control group was subject to only 6 hours traditional face to face learning. The research has been completed after a 10 week application. The data on the research have been collected with German course achievement tests via the German Language Learning Motivation Scale. The results reveal that the experimental group of students attending the German classes in blended learning environments has more success and higher motivation compared to the control group attending German language classes in the traditional learning environment. Even if the learners achieve certain success and motivation findings in the classroom and face to face environments performed along with teaching-learning activities mainly in control of the instructor, the success and motivation effect of the blended learning environment could not be achieved.

Full Text Available This is a report on the capture, transport, and husbandry of Naucrates ductor, also known as pilot fish. Approximately 100 individuals were collected by Flying Sharks in the sequence of an order from multiple public aquaria. Because there is vely limited knowledge about the capture, husbandry and transport of this species, it became necessary to investigate how to achieve this while causing minimum mortality and ensuring animal welfare. Collection was done in the Azores Islands, approximately 20 nautical miles from Horta, using a standard fishing rod and hook, after attracting blue sharks with bait. The animals were transported to shore inside plastic vats and introduced to large 2,0 m wide holding tanks at the Porto Pim Aquarium, where they were held for 2 months. Multiple treatments for wounds, and parasite control, were used and are reported. Transport to mainland Portugal was done aboard a commercial vessel, inside 2,4 m wide polyethylene vats with mechanical and chemical filtration consisting of cartridge filters and protein skimmers, respectively. Once docked on shore the 40 ft. container was then moved to a truck, where it traveled to Spain and France over 6 days. The total transport time of those animals delivered last was therefore 11 days and no mortalities were sustained in transit. The remaining animals were kept in Peniche for 2 more months inside 2,4 m wide polyethylene vats, with filtration consisting of cartridge and protein skimmers, as well as daily water changes. Multiple challenges faced during the collection, holding and transport processes are presented in this presentation.

Fetal development of the pulley for muscle insertion tendons: A review and new findings related to the tensor tympani tendon.

The existence of hard tissue pulleys that act to change the direction of a muscle insertion tendon is well known in the human body. These include (1) the trochlea for the extraocular obliquus superior muscle, (2) the pterygoid hamulus for the tensor veli palatini muscle, (3) the deep sulcus on the plantar aspect of the cuboid bone for the peroneus longus tendon, (4) the lesser sciatic notch for the obturator internus muscle, and (5) the bony trochleariformis process for the tensor tympani muscle tendon. In addition, (6) the stapedius muscle tendon shows a lesser or greater angulation at the pyramidal eminence of the temporal bone. Our recent studies have shown that the development of pulleys Nos. 1 and 2 can be explained by a change in the topographical relationship between the pulley and the tendon, that of pulley No. 3 by the rapidly growing calcaneus pushing the tendon, and that of pulley No. 4 by migration of the insertion along the sciatic nerve and gluteus medius tendon. Therefore, in Nos. 1-4, an initially direct tendon curves secondarily and obtains an attachment to the pulley. In case No. 6, the terminal part of the stapedius tendon originates secondarily from the interzone mesenchymal tissue of the incudostapedial joint. In the case of pulley No. 5, we newly demonstrated that its initial phase of development was similar to No. 6, but the tensor tympani tendon achieved a right-angled turn under guidance by a specific fibrous tissue and it migrated along the growing malleus manubrium.

Full Text Available Indonesia as one of the big developing countries has been responding rapidly to the issue of Corporate Social Disclosure (CSD. This can be seen from the CSD section in the listed companies’ annual reports which keep increasing throughout the years. However, there are still inconclusive findings in factors that determine the extent of CSD. Based on a comprehensive research, therefore, this paper examines some selected factors in their relations to the extent of CSD, both quantitatively and qualitatively. Corporate annual reports for the year 2003 to 2006 were examined to verify the CSD practices by applying a content analysis method and multiple regression analysis. Then, firm’s characteristics (category, size, financial performances, age, and group influential (creditors, auditors, owners were analysed to seek their significant relationships to the extent of CSD. The findings show that (1 there was no significant influence of ‘company type’ to the extent of CSD; but ‘company status’ was significantl y influence CSD (2 ‘company size’, ‘financial performances’, ‘age’, and ‘auditors’ influences’ were found to have significant positi ve influences to the extent of CSD; (3 ‘Owners’ influence’ correlated positivel y rather than negati vely to CSD; and (4 Mixed results were provided by the ‘creditors’ influence’ throughout the years. The overall correlations between predictor and criterion variables are considered to be low to moderate, varied from 0.463 to 0.607 for correlation coefficients (R and 0.215 to 0.368 for determinant coefficients (R2 in the regression model.

Injuring the internal carotid artery (ICA) is a feared complication of endoscopic endonasal approaches. To introduce a comprehensive ICA classification scheme pertinent to safe endoscopic endonasal cranial base surgery. Anatomic dissections were performed in 33 cadaveric specimens (bilateral). Anatomic correlations were analyzed. Based on anatomic correlations, the ICA may be described as 6 distinct segments: (1) parapharyngeal (common carotid bifurcation to ICA foramen); (2) petrous (carotid canal to posterolateral aspect of foramen lacerum); (3) paraclival (posterolateral foramen lacerum to the superomedial aspect of the petrous apex); (4) parasellar (superomedial petrous apex to the proximal dural ring); (5) paraclinoid (from the proximal to the distal dural rings); and (6) intradural (distal ring to ICA bifurcation). Corresponding surgical landmarks included the Eustachian tube, the fossa of Rosenmüller, and levator veli palatini for the parapharyngeal segment; the vidian canal and V3 for the petrous segment; the fibrocartilage of foramen lacerum, foramen rotundum, maxillary strut, lingular process of the sphenoid bone, and paraclival protuberance for the paraclival segment; the sellar floor and petrous apex for the parasellar segment; and the medial and lateral opticocarotid and lateral tubercular recesses, as well as the distal osseous arch of the carotid sulcus for the paraclinoid segment. The proposed endoscopic classification outlines key anatomic reference points independent of the vessel's geometry or the sinonasal pneumatization, thus serving as (1) a practical guide to navigate the ventral cranial base while avoiding injury to the ICA and (2) further foundation for a modular access system.

2010-01-01

In preparation for the radio science experiment of the Lunar Reconnaissance Orbiter (LRO) mission, we analyzed the available radio tracking data of previous NASA lunar orbiters. Our goal was to use these historical observations in combination with the new low-altitude data to be obtained by LRO. We performed Precision Orbit Determination on trajectory arcs from Lunar Orbiter 1 in 1966 to Lunar Prospector in 1998, using the GEODYN II program developed at NASA Goddard Space Flight Center. We then created a set of normal equations and solved for the coefficients of a spherical harmonics expansion of the lunar gravity potential up to degree and order 150. The GLGM-3 solution obtained with a global Kaula constraint (2.5 x 10(exp -4)/sq l) shows good agreement with model LP150Q from the Jet Propulsion Laboratory, especially over the nearside. The levels of data fit with both gravity models are very similar (Doppler RMS of approx.0.2 and approx. 1-2 mm/s in the nominal and extended phases, respectiVely). Orbit overlaps and uncertainties estimated from the covariance matrix also agree well. GLGM-3 shows better correlation with lunar topography and admittance over the nearside at high degrees of expansion (l > 100), particularly near the poles. We also present three companion solutions, obtained with the same data set but using alternate inversion strategies that modify the power law constraint and expectation of the individual spherical harmonics coefficients. We give a detailed discussion of the performance of this family of gravity field solutions in terms of observation fit, orbit quality, and geophysical consistency.

We have analyzed new and previously published radial velocity (RV) observations of MARVELS-1, known to have an ostensibly substellar companion in a ∼6 day orbit. We find significant (∼100 m s –1 ) residuals to the best-fit model for the companion, and these residuals are naïvely consistent with an interior giant planet with a P = 1.965 days in a nearly perfect 3:1 period commensurability (|P b /P c – 3| –4 ). We have performed several tests for the reality of such a companion, including a dynamical analysis, a search for photometric variability, and a hunt for contaminating stellar spectra. We find many reasons to be critical of a planetary interpretation, including the fact that most of the three-body dynamical solutions are unstable. We find no evidence for transits, and no evidence of stellar photometric variability. We have discovered two apparent companions to MARVELS-1 with adaptive optics imaging at Keck; both are M dwarfs, one is likely bound, and the other is likely a foreground object. We explore false-alarm scenarios inspired by various curiosities in the data. Ultimately, a line profile and bisector analysis lead us to conclude that the ∼100 m s –1 residuals are an artifact of spectral contamination from a stellar companion contributing ∼15%-30% of the optical light in the system. We conclude that origin of this contamination is the previously detected RV companion to MARVELS-1, which is not, as previously reported, a brown dwarf, but in fact a G dwarf in a face-on orbit.

Full Text Available Die Gefühle bzw. Emotionen der Lernenden beim Fremdsprachenlehr- und Lernprozess spielen eine wichtige Rolle. Mit der Verknüpfung der Emotion und Kognition beim Lernprozess, haben die positiven Gefühle eine große Bedeutung für den Lernerfolg. Als eine produktive Fertigkeit hat das Sprechen eine wesentlich intensive Beziehung mit den Emotionen, weil es in der realen Zeit fließend laufen muss. Der Lernende soll bei der Sprechproduktion spontan die richtigen Wörter auf die richtige Art und Weise anwenden und sie auch noch verständlich aussprechen. Leider erreicht die Sprechfertigkeit meistens eine niedrigere Niveaustufe als die anderen drei (Schreiben, Lesen und Hören Fertigkeiten im Fremdsprachenunterrichtprozess. Diese qualitative Untersuchung konzentriert sich auf die Daten (Tonaufnahme, die anhand eines Interviews während einer Sprechproduktionsübung im universitären Fremdsprachenunterricht gesammelt wurden. Um die emotionale Dimension der Lernenden während der Sprechproduktion zu identifizieren, wurden im Einzelinterview die Frage „Wie fühlst du dich während du eine Fremdsprache (Englisch sprichst?“ gestellt. Die Teilnehmer dieser Untersuchung waren 29 Studenten, die im WS 2016 - 2017 an Universität Nevşehir Hacı Bektaş Veli (Türkei immatrikuliert waren. Die Auswertung des Interviews folgte mit einer Transkription und einer Interpretation der Tonaufnahmen. Die Meinungen zu der emotionalen Dimension während der Sprechproduktion der Studenten wurden kategorisiert. Die Resultate dieser qualitativen Untersuchung zeigen, dass die emotionale Dimension der Lernenden im universitären Kontext sich in drei Kategorien (positiv, negativ und frühere Ausbildung verteilen.

Strategic biopharmaceutical portfolio development: an analysis of constraint-induced implications.

Optimizing the structure and development pathway of biopharmaceutical drug portfolios are core concerns to the developer that come with several attached complexities. These include strategic decisions for the choice of drugs, the scheduling of critical activities, and the possible involvement of third parties for development and manufacturing at various stages for each drug. Additional complexities that must be considered include the impact of making such decisions in an uncertain environment. Presented here is the development of a stochastic multi-objective optimization framework designed to address these issues. The framework harnesses the ability of Bayesian networks to characterize the probabilistic structure of superior decisions via machine learning and evolve them to multi-objective optimality. Case studies that entailed three- and five-drug portfolios alongside a range of cash flow constraints were constructed to derive insight from the framework where results demonstrate that a variety of options exist for formulating nondominated strategies in the objective space considered, giving the manufacturer a range of pursuable options. In all cases limitations on cash flow reduce the potential for generating profits for a given probability of success. For the sizes of portfolio considered, results suggest that naïvely applying strategies optimal for a particular size of portfolio to a portfolio of another size is inappropriate. For the five-drug portfolio the most preferred means for development across the set of optimized strategies is to fully integrate development and commercial activities in-house. For the three-drug portfolio, the preferred means of development involves a mixture of in-house, outsourced, and partnered activities. Also, the size of the portfolio appears to have a larger impact on strategy and the quality of objectives than the magnitude of cash flow constraint.

Clarifying the Hubble constant tension with a Bayesian hierarchical model of the local distance ladder

Estimates of the Hubble constant, H0, from the local distance ladder and from the cosmic microwave background (CMB) are discrepant at the ˜3σ level, indicating a potential issue with the standard Λ cold dark matter (ΛCDM) cosmology. A probabilistic (i.e. Bayesian) interpretation of this tension requires a model comparison calculation, which in turn depends strongly on the tails of the H0 likelihoods. Evaluating the tails of the local H0 likelihood requires the use of non-Gaussian distributions to faithfully represent anchor likelihoods and outliers, and simultaneous fitting of the complete distance-ladder data set to ensure correct uncertainty propagation. We have hence developed a Bayesian hierarchical model of the full distance ladder that does not rely on Gaussian distributions and allows outliers to be modelled without arbitrary data cuts. Marginalizing over the full ˜3000-parameter joint posterior distribution, we find H0 = (72.72 ± 1.67) km s-1 Mpc-1 when applied to the outlier-cleaned Riess et al. data, and (73.15 ± 1.78) km s-1 Mpc-1 with supernova outliers reintroduced (the pre-cut Cepheid data set is not available). Using our precise evaluation of the tails of the H0 likelihood, we apply Bayesian model comparison to assess the evidence for deviation from ΛCDM given the distance-ladder and CMB data. The odds against ΛCDM are at worst ˜10:1 when considering the Planck 2015 XIII data, regardless of outlier treatment, considerably less dramatic than naïvely implied by the 2.8σ discrepancy. These odds become ˜60:1 when an approximation to the more-discrepant Planck Intermediate XLVI likelihood is included.

Parapharyngeal space can be defined as a potential space surrounded by deglutitional and masticator muscles and their covering, superficial and middle layer of deep cervical fascia. Parapharyngeal space has traditionally been divided by styloid process and fascia of tensor veli palatini muscle (nasopharyngeal level) or fascia of stylopharyngeus muscle (oropharyngeal level) into two compartments, prestyloid and poststyloid spaces. The latter is often called as carotid space. Prestyloid portion exclusively contains fat tissue, which yields hypoabsorption area in CT films and high density area in MRI. In most of papers in radiological journals, the term of parapharyngeal space is regarded as its prestyloid portion which is clearly identified. Axial CT images of 144 patients without any naso- or oropharyngeal lesions were analyzed. Two reference levels of nasopharynx were adopted for the study. The upper level passes through the plane of fossa of Rosenmuller, and the lower reference level transects soft palate. The following parameters of the space were measured; Length and width of the whole space, length and width of prestyloid fatty space, and furthermore, width of pre- and poststyloid space, that were divided by a imaginary line pararell to the axis of the whole space (the upper level); Length and width of the whole space, length of base and height of a triangle of the prestyloid part (the lower level). While parapharyngeal space was symmmetrical in the upper level, the rate of asymmetry amounted to a fourth in the lower level. Prestyloid space was broader than poststyloid one in the upper level. Men were dominant in length of the space in both the upper and the lower level and in length of the base of fatty space in the lower level. There was no difference between any age groups other than in fatty area in the lower level. Teens tended to be narrow, while 60's and older were wide. (author)

Titanium (Ti) is an excellent implantable biomaterial that can be further enhanced by surface topography optimization. Despite numerous data from orthopedics and dentistry, the effect of Ti surface topography on ocular cells is still poorly understood. In light of the recent adaptation of Ti in the Boston Keratoprosthesis artificial cornea, we attempted to perform an extended evaluation of the effect of Ti surface topography on corneal cell adhesion, proliferation, cytotoxicity, transformation, and matrix deposition. Different surface topographies were generated on medical grade Ti-6Al-4V-ELI (extra-low interstitial), with linearly increased roughness (polished to grit blasted). Biological response was evaluated in vitro using human corneal limbal epithelial (HCLE) cells, stromal fibroblasts (HCF), and endothelial cells (HCEnC). None of the Ti surface topographies caused cytotoxicity to any of the three corneal cell types. However, rough Ti surface inhibited HCLE and HCF cell adhesion and proliferation, while HCEnC proliferation was unaffected. Long-term experiments with HCF revealed that rough Ti surface with R(a) (the arithmetic average of the profile height from the mean line) ≥ 1.15 μm suppressed HCF focal adhesion kinase phosphorylation, changed fibroblast morphology, and caused less aligned and reduced deposition of collagen matrix as compared to smooth Ti (R(a) ≤ 0.08 μm). In the presence of transforming growth factor β1 (TGFβ1) stimulation, rough Ti inhibited alpha-smooth muscle actin (α-SMA) expression and collagen deposition, leading to decreased myofibroblast transformation and disorganization of the collagen fibrils as compared to smooth Ti. This study suggests that Ti surface topography regulates corneal cell behavior in a tissue-dependent manner that varies across the corneal strata. Contrary to the accepted paradigm, smooth surface topography can enhance cell adhesion and proliferation and increase matrix deposition by corneal cells.

Ex situ conservation strategies for threatened species often require long-term commitment and financial investment to achieve management objectives. We present a framework that considers the decision to adopt ex situ management for a target species as the end point of several linked decisions. We used a decision tree to intuitively represent the logical sequence of decision making. The first decision is to identify the specific management actions most likely to achieve the fundamental objectives of the recovery plan, with or without the use of ex-situ populations. Once this decision has been made, one decides whether to establish an ex situ population, accounting for the probability of success in the initial phase of the recovery plan, for example, the probability of successful breeding in captivity. Approaching these decisions in the reverse order (attempting to establish an ex situ population before its purpose is clearly defined) can lead to a poor allocation of resources, because it may restrict the range of available decisions in the second stage. We applied our decision framework to the recovery program for the threatened spotted tree frog (Litoria spenceri) of southeastern Australia. Across a range of possible management actions, only those including ex situ management were expected to provide >50% probability of the species’ persistence, but these actions cost more than use of in situ alternatives only. The expected benefits of ex situ actions were predicted to be offset by additional uncertainty and stochasticity associated with establishing and maintaining ex situ populations. Naïvely implementing ex situ conservation strategies can lead to inefficient management. Our framework may help managers explicitly evaluate objectives, management options, and the probability of success prior to establishing a captive colony of any given species.

Purpose: To examine the usefulness of MR imaging for predicting local control of nasopharyngeal carcinoma (NPC) and the value of MR imaging in the newly published fifth edition of the TNM classification. Methods and Materials: We studied 29 patients with NPC with MR imaging and CT before and after treatment. Staging was done according to the fourth and newly published fifth editions of the International Union Against Cancer (UICC) staging system. The radiotherapy protocol was designed to deliver 66 to 68 Gy to the primary tumor and clinically involved nodes. Results: MR proved better than CT at identifying obliteration of the pharyngobasilar fascia, invasion of the sinus of Morgagni, through which the cartilaginous portion of the eustachian tube and the levator veli palatini muscle pass, invasion of the skull base, and metastases to lymph nodes in the carotid and retropharyngeal spaces. All seven patients without invasion of the pharyngobasilar fascia had local control. The local control rates of patients with invasion of the skull base were not good (60 to 73%). There was no apparent relationship between tumor volume determined by T1-weighted MR images and local control when the tumor volume was more than 20 cc. The newly published N staging system appears to successfully identify the high-risk group for distant metastasis as N3. In our series, four of five patients with N3 disease developed distant metastases. Conclusion: Deep infiltration of the tumor is a more important prognostic factor in NPC than tumor volume. Since the newly published T staging system requires a search for tumor invasion into soft tissue such as parapharyngeal space and bony structures, MR imaging may be indispensable for the newly published NPC staging system

In the past decade, there has been increased utilization of magnetic resonance imaging (MRI) in evaluating and understanding velopharyngeal insufficiency (VPI). To our knowledge, none of the prior studies with MRI has simultaneously linked the audio recordings of speech during cine MRI acquisition with the corresponding images and created a video for evaluating VPI. To develop an MRI protocol with static and cine sequences during phonation to evaluate for VPI in children and compare the findings to nasopharyngoscopy and videofluoroscopy. Five children, ages 8-16 years, with known VPI, who had previously undergone nasopharyngoscopy and videofluoroscopy, were included. MRI examination was performed on a 3-T Siemens scanner. Anatomical data was obtained using an isotropic T2-weighted 3-D SPACE sequence with multiplanar reformation capability. Dynamic data was obtained using 2-D FLASH cine sequences of the airway in three imaging planes during phonation. Audio recordings were captured by a MRI compatible optical microphone. All five cases had MRI and nasopharyngoscopy and four had videofluoroscopy performed. VPI was identified by MRI in all five patients. The location and severity of the velopharyngeal gap, closure pattern, velar size and shape and levator veli palatini (LVP) muscle were identified in all patients. MRI was superior in visualizing the integrity of the LVP muscle. MRI was unable to identify hemipalatal weakness in one case. In a case of stress-induced VPI, occurring only during clarinet playing, cine MRI demonstrated discordant findings of a velopharyngeal gap during phonatory tasks but not with instrument playing. Overall, there was satisfactory correlation among MRI, nasopharyngoscopy and videofluoroscopy findings. Cine MRI of the airway during speech is a noninvasive, well-tolerated diagnostic imaging tool that has the potential to serve as a guide prior to and after surgical correction of VPI. MRI provided superior anatomical detail of the levator

Data on hospitalizations were obtained from the Finnish Hospital Discharge Register.Results: In the early stages of T1DM, the majority of the use of hospitalizations was due to the treatment of T1DM without complications. Enormous increases were found for complications when diabetes lasted longer (from 9.5 to 16.5 years. For women, the yearly number of bed-days for renal complications increased 4.8-fold, for peripheral vascular disease 4.3-fold, and for ophthalmic complications 2.5-fold. For men, the corresponding increases were as follows: 5-fold, 6.9-fold, and 2.5-fold. The yearly number of bed-days for nephropathy increased 7-fold. Bed-days for T1DM without complications dropped dramatically. The length of stay in hospitalizations decreased notably, but hospital visits increased when the duration of T1DM increased.Conclusions: Hospitalizations due to complications substantially increase with aging of T1DM patients. Prevention of T1DM is strongly needed. Keywords: T1DM, inpatient care, hospitalizations, complications

The deviation of the observed frequency of a word w from its expected frequency in a given sequence x is used to determine whether or not the word is avoided . This concept is particularly useful in DNA linguistic analysis. The value of the deviation of w , denoted by [Formula: see text], effectively characterises the extent of a word by its edge contrast in the context in which it occurs. A word w of length [Formula: see text] is a [Formula: see text]-avoided word in x if [Formula: see text], for a given threshold [Formula: see text]. Notice that such a word may be completely absent from x . Hence, computing all such words naïvely can be a very time-consuming procedure, in particular for large k . In this article, we propose an [Formula: see text]-time and [Formula: see text]-space algorithm to compute all [Formula: see text]-avoided words of length k in a given sequence of length n over a fixed-sized alphabet. We also present a time-optimal [Formula: see text]-time algorithm to compute all [Formula: see text]-avoided words (of any length) in a sequence of length n over an integer alphabet of size [Formula: see text]. In addition, we provide a tight asymptotic upper bound for the number of [Formula: see text]-avoided words over an integer alphabet and the expected length of the longest one. We make available an implementation of our algorithm. Experimental results, using both real and synthetic data, show the efficiency and applicability of our implementation in biological sequence analysis. The systematic search for avoided words is particularly useful for biological sequence analysis. We present a linear-time and linear-space algorithm for the computation of avoided words of length k in a given sequence x . We suggest a modification to this algorithm so that it computes all avoided words of x , irrespective of their length, within the same time complexity. We also present combinatorial results with regards to avoided words and absent words.

Scaling Big Data Cleansing

KAUST Repository

Khayyat, Zuhair

Data cleansing approaches have usually focused on detecting and fixing errors with little attention to big data scaling. This presents a serious impediment since identify- ing and repairing dirty data often involves processing huge input datasets, handling sophisticated error discovery approaches and managing huge arbitrary errors. With large datasets, error detection becomes overly expensive and complicated especially when considering user-defined functions. Furthermore, a distinctive algorithm is de- sired to optimize inequality joins in sophisticated error discovery rather than na ̈ıvely parallelizing them. Also, when repairing large errors, their skewed distribution may obstruct effective error repairs. In this dissertation, I present solutions to overcome the above three problems in scaling data cleansing. First, I present BigDansing as a general system to tackle efficiency, scalability, and ease-of-use issues in data cleansing for Big Data. It automatically parallelizes the user’s code on top of general-purpose distributed platforms. Its programming inter- face allows users to express data quality rules independently from the requirements of parallel and distributed environments. Without sacrificing their quality, BigDans- ing also enables parallel execution of serial repair algorithms by exploiting the graph representation of discovered errors. The experimental results show that BigDansing outperforms existing baselines up to more than two orders of magnitude. Although BigDansing scales cleansing jobs, it still lacks the ability to handle sophisticated error discovery requiring inequality joins. Therefore, I developed IEJoin as an algorithm for fast inequality joins. It is based on sorted arrays and space efficient bit-arrays to reduce the problem’s search space. By comparing IEJoin against well- known optimizations, I show that it is more scalable, and several orders of magnitude faster. BigDansing depends on vertex-centric graph systems, i.e., Pregel

To study the inhibitory effect of Sommerlad technique on the growth of the maxilla by comparing the wound healing between Sommerlad and Von Langenbeck techniques in repair of isolated cleft palate. A retrospective cohort study was conducted on 54 patients with isolated cleft palate who received palatoplasty with levator veli palatini retropositioning according to Sommerlad between June 2005 and August 2011 as trial group; 89 cleft patients received Von Langenbeck technique repair between June 2003 and September 2006 as control group. There was no significant difference in gender and age between 2 groups (P > 0.05). The operation time, intraoperative blood loss, body temperature, and fever were recorded and compared; the wound healing was observed, and the palatal mucosa was graded according to Karsten standard. The operation time of trial group [(72.2 ± 5.5) minutes] was significantly longer than that of control group [(58.1 ± 6.8) minutes] (t = 4.494, P = 0.000); the intraoperative blood loss of trial group [(18.6 ± 6.5) mL] was significantly less than that of control group [(34.2 ± 10.2) mL] (t = 2.447, P = 0.000). Within postoperative 48 hours, the highest body temperature was 36.6-37.6°C (mean, 36.9°C) in trial group, and was 36.8-38.2°C (mean, 37.3°C) in control group; fever occurred in 5 patients (9.3%) of trial group and 21 patients (23.6%) of control group, showing significant difference (χ2 = 4.640, P = 0.030).

Full Text Available Sheikh Pir Havend had established a dervish lodge in the village of Şeyh attached to the sub-district of Komanat in the district of Tokat probably in the second half of the twelfth century or at the beginnings of the thirteenth century. He made over the malikâne income of three villages and one arable land [mezra] in the sub-districts of Komanat and Kafirni in the district of Tokat to this dervish lodge. Some documents exist in our national archives and the Religious Court Registers of Tokat on the waqf of the dervish lodge. However, there is not enough information on the identity of Sheikh Pir Havend in the written sources. In his book Seyahatname [The Book of Travel], Evliya Çelebi identified the dervish lodge of Sheikh Pir Havend among the dervish lodges of the Bektashi order in Tokat. In the light of this information, we can consider that Sheikh Pir Havend was one of the followers of Hacı Bektash Veli and his descendants were also followers of the Bektashi order. Arts historians have made some evaluations on the Tomb of Sheikh Pir Havend which exists in the village of Çöreğibüyük in Tokat. In an article related to Bektashi dervish lodges and shrines in the Seyahatname of Evliya Çelebi, a short information on the dervish lodge of Sheikh Pir Havend was provided. Investigating this dervish lodge and the nearby tomb in every aspect will be useful for our cultural history. In addition, the article will contribute to the religious, social and cultural history of Tokat. This article provides an in-depth investigation of the dervish lodge of Sheikh Pir Havend which was an important dervish lodge of Bektashi order in the past and the tomb of Çöreğibüyük with the help of new documents. It was found that the dervish lodge of Sheikh Pir Havend does not have waqf revenues at the present and that the Bektashi religious culture still exists in the village of Çöreğibüyük or Şeyh where the dervish lodge of Sheikh Pir Havend was

The Late Holocene in the northern Adriatic is characterized by the eustatic peak of the sea-level rise, followed by the equilibrium between the regional tectonic subsidence and hydro-isostatic emergence and relatively stable sea level for a few thousand years. During this period the area experienced changes in sedimentation rate, food/oxygen availability in the benthic ecosystem and eutrophication with seasonal hypoxic and anoxic events. In order to reconstruct the marine paleoecology in the Brijuni Islands area during this period, a multidisciplinary study was carried out, including geochemical (TOC, trace metals, carbonate content), micropaleontological analyses (benthic foraminifera) and dating of sediments and mollusc shells. The principal aim of this study is to observe the effects of ecological shifts on foraminiferal assemblages during the Late Holocene. One core of 1.5 m length was taken at a sampling station south of Veli Brijuni Island, located within a marine protected area with no fishing/dredging pressure (Croatian national park). The core was sliced into smaller subsamples, and four sediment fractions of each subsample (63, 125, 250 and 500 µm) were analyzed for standard properties of the foraminiferal community (species richness, faunal composition, biodiversity indices), in comparison with relevant physical and geochemical properties of the sediment. The results concerning changes in foraminiferal species composition and abundance point to differences within the core: surface sediments are dominated by suspension feeders (Planorbulina mediterranensis, Lobatula lobatula, Cibicides variabilis, Cibicides refulgens), whereas deposit feeders (genera Textularia, Siphonaperta, Adelosina, Trioculina) appear in higher abundances at approximately 30 cm of the sediment depth and dominate down-core. Species richness in the first 30 cm is lower (10 to 34 species per sample) in comparison to the middle part of the core (39 to 53 species), and decreases again at

Full Text Available Location and length of hamulus process plays a very important role in the efficiency of muscles such as tensor veli palatine, palato pharyngeal, upper part of upper throat muscle and so on. Given the importance of information on the morphology of the hamular process and capabilities and usefulness of CBCT in the diagnosis of its structure, this study takes place with the goal of investigating the morphologic indices (indicators of hamulus pterygoid process using CBCT. This study investigates the CBCT images of 201 patients with the average age of 37 years, 102 males and 99 females. The length and width of the hamulus process on the left and right was measured. Also, the slope of this process in the sagittal and coronal planes were studied. Then variables in question were measured by a CBCT viewer. Average length of hamulus pterygoid process on the right was found to be 6.4 mm and on the left it was 6.5 mm. Average width of hamulus pterygoid process on the right was found to be 1.34 mm and on the left it was 1.35 mm. The average slope of the hamulus pterygoid process in the sagittal plane on the right was found to be 55.9 ° and on the left it was 56.7° The average slope of the hamulus pterygoid process in the coronal plane on the right was found to be 65.7 ° and on the left it was 66.5°. Average length and width of the hamulus process on the two sides did not make a statistically significant difference. But the average slope in the sagittal and coronal plane on the left was significantly higher than the one on the right. Average length of hamulus pterygoid process on the two sides was significantly higher in men than women. Average width of hamulus pterygoid process and the slope in the sagittal and coronal planes did not make any difference on both sides in both genders. Average length, width and slope of hamulus pterygoid process in the sagittal plan reduces on both sides with increase in age. But the slope of the hamulus pterygoid process

Treating inertia in passive microbead rheology.

The dynamic modulus G(*) of a viscoelastic medium is often measured by following the trajectory of a small bead subject to Brownian motion in a method called "passive microbead rheology." This equivalence between the positional autocorrelation function of the tracer bead and G(*) is assumed via the generalized Stokes-Einstein relation (GSER). However, inertia of both bead and medium are neglected in the GSER so that the analysis based on the GSER is not valid at high frequency where inertia is important. In this paper we show how to treat both contributions to inertia properly in one-bead passive microrheological analysis. A Maxwell fluid is studied as the simplest example of a viscoelastic fluid to resolve some apparent paradoxes of eliminating inertia. In the original GSER, the mean-square displacement (MSD) of the tracer bead does not satisfy the correct initial condition. If bead inertia is considered, the proper initial condition is realized, thereby indicating an importance of including inertia, but the MSD oscillates at a time regime smaller than the relaxation time of the fluid. This behavior is rather different from the original result of the GSER and what is observed. What is more, the discrepancy from the GSER result becomes worse with decreasing bead mass, and there is an anomalous gap between the MSD derived by naïvely taking the zero-mass limit in the equation of motion and the MSD for finite bead mass as indicated by McKinley et al. [J. Rheol. 53, 1487 (2009)]. In this paper we show what is necessary to take the zero-mass limit of the bead safely and correctly without causing either the inertial oscillation or the anomalous gap, while obtaining the proper initial condition. The presence of a very small purely viscous element can be used to eliminate bead inertia safely once included in the GSER. We also show that if the medium contains relaxation times outside the window where the single-mode Maxwell behavior is observed, the oscillation can be

The 'Byzantinisms' of king Stefan Radoslav

Full Text Available The life-style and politics of Stefan Radoslav bear the mark of activities that indicated his special attachment to the Byzantine world. These activities were prompted by a combination of ideological ambitions and political reality, but they were not in keeping with the modest achievements of Radoslav's reign. Moreover, most of these activities belong to the time when Radoslav was heir to the throne. There is no doubt that Stefan Nemanjić the Grand Zhupan and subsequently the first crowned king, had exclusive connections with the Byzantine dynasty of the Angeloi, especially with the emperor Alexios III (1195-1203. In that context, the donor's inscription in the basic ring of the dome in the Church of the Mother of God in Studenica (1208, in which his father Stefan Nemanja, is mentioned as (former 'veleslavni gospodin vse srbske zemlje veli(ki župan i svat cara grčkog kir Alesija', is quite indicative. This ideological construction would acquire a contour in reality by means of a political marriage with one of the female offspring of Angeloi lineage, which would represent an alternative solution to Stefan's failed marriage with Eudocia, daughter of the emperor Alexios. Instead, several years elapsed in waging war with the Latins, the Bulgarians and the State of Epiros. However, efforts to create firmer, more tangible ties with the Angeloi dynasty from Epiros were not forgotten. Therefore, the Serbian monarch brought his eldest son Radoslav into play, intending to have him act as a link with the Angeloi bloodline. As a result of all this, the final attempt to have Radoslav become the husband of a princess from the Angelos dynasty is not surprising. At the end of 1219 or the beginning of 1220, he married Anna Doukaina, the daughter of the epirotic ruler Theodore I Angelos Doukas Komnenos, which at that point represented a marriage connection of the highest possible level between two ruling houses. Stefan's insistence on Serbia acquiring a stake

�CHODISKA: Existuje několik faktorů (počáteční poloha skokana na lyžích a její změny v průběhu přechodové fáze letu, velikost a směr vektoru rychlosti pohybu těžiště skokana, velikost aerodynamické odporové a vztlakové síly apod., které určují trajektorii soustavy skokan + lyže a tím i dosaženou délku skoku. CÍLE: Cílem studie je představit metodu řešení úlohy optimálního řízení letové fáze skoku na lyžích se třemi omezenými řídicími proměnnými – úhel náběhu (a, úhel trup vs. lyže (b, úhel levá lyže vs. pravá lyže (V – na základě Pontrjaginova principu maxima. METODIKA: Kritériem optimality byla zvolena délka skoku. Jako zdroj informací o závislosti veličin L (lift area a D (drag area na řídicích proměnných byla použita převzatá regresní funkce s tabelovanými regresními koeficienty. Srovnány byly trajektorie referenčního a optimalizovaného skoku s profilem můstku K = 125 m ve Frenštátě pod Radhoštěm a stanoveny odpovídající délky skoku, aerodynamické odporové a vztlakové síly, velikosti rychlosti pohybu těžiště soustavy skokan + lyže, její vertikální a horizontální složky. Aby byly respektovány reálné polohy v letové fázi skoku, přípustné hodnoty řídicích proměnných náležely v každém okamžiku ohraničené množině. VÝSLEDKY: Bylo zjištěno, že skokan by měl na ohraničené množině přípustných hodnot řídicích proměnných minimalizovat úhly (a a (b, úhel (V naopak maximalizovat. Prodloužení skoku vlivem optimalizace je 17 %. ZÁVĚRY: Pro možnost dalšího výzkumu je nezbytné využití regresní analýzy pro experimentální data při určení závislosti aerodynamických sil působících během letu na soustavu skokan + lyže. To platí také pro aplikaci kontrolních proměnných vztahujících se k základním fyzickým a psychickým vlastnostem skokanů na lyžích.

onlara doğru yolu göstermeye çalışmıştır. Seksen beş yıllık ömründe kendinden önceki geleneği başarılı bir şekilde devam ettirmiş ve Anadolu toplumu içerisinde kardeşlik bağı oluşturmaya çalışmıştır. Fedâî Baba was born in 1855 in Yassıçal, one of the central villages of Amasya, and he passed away in 1940. It is rumored that this Aşık who had a different personality stayed in tombs in his childhood. He studied madrasa in Amasya for a while. According to a widespread rumour, he left madrasa before he completed his education. In Erbaa, a town in Tokat province, he received the Sufi knowledge from Deruni Baba descended from entombed Sheikh Mahmut Veli. There are two hundred and fifty two known poems belonging to this Aşık whose miracles have been told. Fedâî Baba, known for his ingenuity in his dreams in accordance with the tradition of loveliest poetry, can not play the saz, but has the ability to sing poetic poem. He is a kind traveler as he frequently visits Amasya as a folk Aşık. He sang poems in accordance with both Ottoman and folk poetry styles. The poems which he composedin ottoman poetry style are more complex than his poems in folk poetry in terms of language. Fedâî Baba who seems to have the ability towards poetry has a lyrical style. It is seen that his poems reflect this tradition as he is a member of the Alevi Bektashi tradition, which expresses the essence of the Sufi tradition such as “İlmi ledün, mürşit, zikir, dört kapı, ilahi aşk, tevhit”. He masterfully blended the basic features of Sufism and Bektashi cultures in his poems. Amasya has an important place in Alevi Bektashi culture. Fedâî Baba has not been investigated much even though he had a strong influence in this area. In this work, his biography has been focused and in line with his poems his prominence and mysticism in Alevi Bektashi culture has been put forward. This Aşık, who should be considered as a value of Amasya, tried to educate

Therefore, the newly discovered statues produced by Giuseppe are a significant contribution to his personal 174 Damir Tulić: Nepoznati anđeli Giuseppea Groppellija u Zadru... Ars Adriatica 6/2016. (155-174 oeuvre. It is difficult to distinguish between his statues and those by his brother, but it is generally believed that Paolo was a better artist. It is therefore important to compare the two sculptures, as they are believed to have been made independently. Paolo’s statue of Our Lady of the Rosary (1708 was originally located in the former Benedictine church of Santa Croce at Giudecca in Venice, and acquired early in the 19th century for the parish church of Veli Lošinj. If one compares the phisiognomy of the Christ Child by Paolo to that of Giuseppe’s signed sculpture of angel-putto in Zadar, one can observe considerable similarities (Figs. 5 and 6. However, Paolo’s sculptures are somewhat subtler and softer than Giuseppe’s. The workshop of Giuseppe and Paolo Gropelli has also been credited with two large marble angels on the main altar of the parish church in Concadirame near Treviso, as they show great similarity in style to the angels in Ljubljana’s cathedral, made around 1710 (Figs. 7, 8, 9, and 10. The oeuvre of Giuseppe and Paolo Gropelli can also be extended to two kneeling marble angels at the altar of the Holy Sacrament in the Venetian church of Santa Maria Formosa, with their marble surface somewhat damaged (Figs. 11 and 12. Coming back to the former main altar in Zadar’s church of St Donatus, it should be emphasized that it was erected following the last will of Archbishop Vettore Priuli (1688-1712, that contains a clearly expressed desire that the altar should be decorated as lavishly as possible. As the construction contract has been lost and the appearance of the altar remains unknown, it can only be supposed what

Рост производственных объемов порошковых изделий, изготовленных методом ультразвукового распылительного пиролиза способствовал успешному внедрению данного метода для синтеза порошка серебра из раствора серебра нитрата. / Nanotehnologija pripada ključnim inovativnim tehnologijama za proizvodnju prahova. Raspršivanje prahova ultrazvučnom pirolizom višestruko je korišćeno za formiranje čestica nanoprahova metala, oksida i kompozita. Ovaj rad odnosi se na nanočestice srebra, bakra i zlata, formiranih ultrazvučnom pirolizom korišćenjem horizontalnog i vertikalnog reaktora. Direktna sinteza nanočestica na bazi Ru-TiO2 i RuO2-TiO2 sa strukturom sastavljenom od jezgra i ljuske dalje je ispitivana. Molarni udeli prekursora, tip rastvarača i procesna temperatura imaju odlučujuću ulogu u formiranju čestica sa ovom kombinovanom strukturom. Zatim, ispitivan je uticaj reakcionih parametara (temperatura, vreme zadržavanja, koncentracija rastvora i frekvencija ultrazvuka na morfološke karakteristike pripremanih nanočestica. Uvećanje temperature od 150°C do 1000°C vodi od jednog nepravilnog oblika do proizvodnje sfernih čestica. Nakon toga, bio je predložen model formiranja metalnih nanočestica od kapi aerosola. Korišćenjem procesa raspršivanja preko ultrazvučne pirolize idealno sferne čestice dobijene su na temperaturi ispod tačke topljenja. Uređaj za određivanje raspodele veličine čestica korišćenjem različite pokretljivosti čestica u elektrostatičkom polju korišćen je za on-line analizu tokom proizvodnje čestica.

. Negativan uticaj tih kretanja, odnosno dinamičkih opterećenja koje ona izazivaju i prenose na noseći sistem vozila, može se smanjiti pravilnim izborom položaja i karakteristika oslonaca pogonske grupe. U praksi se usaglašavanje karakteristika oslonaca pogonske grupe, najčešće, vrši iz uslova minimalne buke i vibracija vozila, pri čemu se, uglavnom, zanemaruju toplotna opterećenja kojima su oni izloženi u eksploataciji, a zna se da ona neminovno dovode do oštećenja samih oslonaca i narušavanja njihovih karakteristika. Treba napomenuti da elasto-prigušne sile u osloncima vrše mehanički rad koji se pretvara u toplotnu energiju. Analiza toplotnih opterećenja oslonaca može se vršiti korišćenjem teoretskih, eksperimentalnih i kombinovanih metoda. U ovom radu istraživanja su vršena primenom teorijskih metoda uz korišćenje uprošćenog mehaničkog modela pogonske grupe. Pri tome su posmatrane vibracije pogonske grupe teretnog motornog vozila srednje klase iz proizvodnog programa FAP 1314. Imajući u vidu zastupljenost klasičnih (gumeno-metalnih i hidrauličkih oslonaca pogonske grupe kod savremenih teretnih motornih vozila, u radu su izvršene analize toplotnih opterećenja pomenutog vozila, uz korišćenje matematičkog modela. Realizovana istraživanja imala su za cilj da se utvrdi odnos toplotnih opterećenja klasičnih i hidrauličkih oslonaca, uz pomoć modela, pa se dobijeni rezultati mogu usvojiti kao orijentacioni, što je neophodno u fazi izrade idejnog projekta teretnog motornog vozila. Analiza je pokazala da je razvijena količina toplote kod hidrauličkih oslonaca višestruko veća nego u slučaju korišćenja klasičnih oslonaca. Pored toga, izračunate parcijalne funkcije koherenci toplotnog fluksa su pokazale da su njihove vrednosti u intervalu 0,216 do 1, što ukazuje na to da postoji veza između ulaznih veličina i toplotnog fluksa. Pri tome, veći uticaj na toplotna opterećenja oslonaca pogonske grupe imaju inercijalna sila i obrtni
